However, the conventional replaceable button has the following problems.
In the combination button disclosed in Japanese Patent Application Laid-Open No. 10-113204 of Patent Document 1, it is necessary to form the outer periphery of the decorative portion 2 provided with the button top with a metal plate that can be easily bent by hand. There is a problem that it is limited to a very narrow thing. Specifically, it is a technique suitable for a button top such as a so-called gold button used for a blazer or the like, and is a technique that is difficult to apply to a general-purpose plastic button.

  Next, the combination button disclosed in Japanese Patent Application Laid-Open No. 2005-334093 of Patent Document 2 has a problem that the decorative member 10 having a button top is also limited. The decorative member 10 having a button top has a so-called bag shape, and a button insertion portion 20 corresponding to the mouth of the bag is made of a material that can be expanded and contracted. is there. In other words, the button top must be bag-shaped, and the back side of the button top must be made of a stretchable material. The button top on the front side is made of a hard plastic material, and the back side is made of a stretchable material, such as cloth. In general, it is difficult to manufacture a button using such a combination of different materials, and it is difficult to manufacture the button itself, and the supply of the button is limited.

  Next, in the button and its fastener that do not use the thread disclosed in Japanese Patent Application Laid-Open No. 2000-356606 of Patent Document 3, although the button top itself can be easily replaced, the structure is complicated because it has four members. Furthermore, since the button top is attached by the clip-shaped lock spring 12, the button top is idle and, for example, the button top is attached in a facing direction. There is a problem that it cannot be maintained.

  In view of the above problems, the present invention can easily replace the button top and does not come off easily, and as a material for the button, a general-purpose plastic button or metal button can be used. It is an object of the present invention to provide a replaceable button that can be easily manufactured in any case and that can be attached while maintaining the button in a beautifully facing direction in the mounting position of the button.

  In order to solve the above-mentioned problems, a replaceable button of the present invention includes a base, a base structure provided on the base, a threading hole or a shank, and the threading hole or the shank by a thread. A button base that can be sewn to a predetermined button attachment position via a shank; a button top portion provided with a button top on the surface; and a button body structure provided at a lower portion of the button top portion; A button main body supported by being combined with the base; combining the button main body with the button base; fitting the base structure and the button main body structure; The button base is removable and replaceable.

There are several types of replaceable buttons of the present invention.
In the first type, the base structure on the button base side includes a so-called “male” structure, and the button main body structure on the button body side includes a so-called “female” structure. The structure and the female button body structure can be fitted together and combined.
In the second type, the base structure on the button base side includes a so-called “female” structure, and the button main body structure on the button body side includes a so-called “male” structure. The structure and the male button body structure can be fitted together and combined.

A configuration example of the first type is given below.
In the first type of configuration example, the base structure is a locking rod having a long side and a short side provided on the base, and the button main body structure is provided on the lower part of the button top portion. A stop receiving portion, a hole portion having a long side and a short side corresponding to the lock hook of the button base provided on the back surface of the lock receiving portion, and a lock receiving portion corresponding to the short side of the hole portion Provided with a slit having a gap corresponding to the thickness of the locking rod. After inserting these so that the long sides and short sides of each other cover the hole of the button body structure with respect to the locking rod of the base structure, rotate the button body, The button body can be attached to and detached from the button base by fitting the distal end portion of the long side into the slit portion.
With the above configuration, the replaceable button of the present invention according to the first type can be obtained by sewing the button base with a thread through a threading hole or a shank like a normal button to a predetermined position of the clothes. After that, simply by covering the button base with the hole on the button base structure and turning the button base, it can be held by fitting the hook into the slit. The body can be easily attached to the button base.

In addition, as an example of the shape of the latch receiving portion, there is one in which a part of the cylinder is formed in the long side portion, and the locus passing through the outermost periphery in the rotation of the latch rod is the inner diameter of the cylinder.
In addition, as an example of the shape of the locking rod, there is a shape in which a part of the disk is formed in the long side portion and the disk is cut off in the short side portion. The shape of the base located under the locking rod may be a rectangle or a rectangle with rounded corners.
Here, it is preferable to devise a device for controlling the rotation of the button body.
For example, the button body is provided with a contact structure that contacts a part of the button base when the button body is rotated with a predetermined angle by rotating the button body with the button base covered with the button base. There is a device that stops the rotation of the button body relative to the base. This device determines the position where the button body rotates and stops, and can provide a steady state.
For example, the button base has a substantially rectangular cross section, and of the two corners on the diagonal line, one corner is rounded to a short distance angle close to the rotation axis, and one corner is rounded. In the rotational movement of the lock receiving portion of the button main body, the rotational trajectory of the structure having the innermost rotational trajectory is the short distance angle. A contact structure can be obtained by adjusting to contact the long distance angle without contacting.

Next, a configuration example of the second type is given below.
In the configuration example of the second type, the base structure includes a hole provided in the base and a notch structure adjacent to the hole, and the button main body structure is provided in the hole. A protrusion structure that can be inserted, and includes a pillar part and a protrusion part that is provided at the tip of the pillar part and fits into the notch structure body. By inserting the protrusion structure of the button body structure into the hole of the base structure and rotating the button body, the protrusion structure and the notch structure can be fitted and attached.
With the above configuration, the replaceable button of the present invention can be obtained by sewing the button base with a thread through a threading hole or a shank at a predetermined position of the clothing like a normal button. Just by inserting the projecting structure into the hole of the button base and turning it, it can be held by fitting and holding the notch structure, and the button body can be easily attached to the button base. .

Here, the combination of the notch structure of the button base and the protrusion of the button body in the second type may have the following first pattern and second pattern.
In the first pattern, the notch structure of the button base is provided outwardly on the back side of the button base out of the hole edge, and the outline is an arc-shaped notch, When the button body's protrusion is a rod-shaped body and the button body is rotated around the pillar, the protrusion's rod-shaped body is rotatable within the notch of the button base's notch structure. is there.
Here, the height of the column portion is equivalent to the thickness of the plate portion of the cutout structure of the button base, and when the button body is rotated around the column portion, the protrusion of the button body If the thickness of the plate portion is sandwiched between the edge and the back surface of the button body, the button body can be stably attached to the button base.
In addition, a notch is provided between the pillar and the protrusion, and the height of the notch is a height corresponding to the thickness of the plate part of the notch structure of the button base. When the button body is rotated to the center, the button body can be stably attached to the button base even if the thickness of the plate portion is sandwiched by the notch portion of the button body.

Here, when the button body is rotated and attached to the button base, a contact body having a contact body structure with a thick wall is formed at the notch edge of the notch structure so that the mounting posture is easily stabilized. It is preferable that when the button body is rotated with respect to the button base, the rotation stops when a part of the protruding structure abuts against the abutment structure.
In this way, by providing a contact body that forms a contact body structure, when the protrusion structure is inserted into the hole and the button body is rotated, the protrusion rotates in the cutout structure. Eventually, the contact with the contact body structure stops the rotation, and the mounting posture is stabilized.

Next, as for the 2nd pattern, the notch structure of a button base is provided toward the outer side in the back surface side of a button base among hole edge, and the outline has a plurality of circular arc shape Repetition of concave and convex parts, when the button body and button base are combined, the height of the button body protrusion matches the height of the cutout structure of the button base Is. Here, when the protrusion structure is rotated in a state where it is inserted into the hole of the button base, the arc locus drawn by the tip of the protrusion is outside the arc connecting the convex portions of the contour line of the notch structure. And the button body is locked to the button base by rotating the button body and fitting the protrusion into one of the recesses in the cutout structure. It can be done.
Here, a plurality of projections of the button main body are provided at positions facing each other across the column part, and the recesses of the notch structure of the button base are located at positions facing each other on the circumference in pairs. In the state where the protrusion is fitted to the cutout structure, the two portions are simultaneously fitted at positions facing each other with the pillar portion interposed therebetween. Therefore, it can be firmly fastened on both sides across the central column, and the locked state is maintained in a stable form.

  As seen above, the replaceable buttons according to the present invention include the first type, the second type, the first pattern in the second type, the second pattern, etc. In any case, the button body can be integrally formed of, for example, plastic, and can be manufactured by a conventional button molding technique. Therefore, variations of the button body can be various. In addition, the button can be attached to the button base with respect to the button base, and if the button base is correctly attached to the clothes, the button main body can be attached in the correct posture.

Here, the replaceable button according to the present invention is simple so that the stability of the button body attached to the button base is increased regardless of whether the button is the first type or the second type. It is preferable to devise the structure so as not to reversely rotate.
For example, the part for fitting the base structure of the button base is provided with a spiral inclination around the central axis of the button base, or the part for fitting the main body structure of the button body By providing a spiral inclination around the central axis of the main body structure, when the button main body is rotated, the button main body is tightened in a direction approaching the button base. If a spiral inclination is provided in this way, the button body will be screwed when rotated, and the button body will be tightened in the direction approaching the button base, causing strong friction at the fitting location, Stability increases in the mounting posture of the main body to the button base, and it can be easily fixed so as not to reversely rotate. It cannot be easily removed in daily operations.

According to the replaceable button of the present invention, the replaceable button of the present invention can be obtained by sewing the button base into a predetermined position on the garment with a thread like a normal button. By simply inserting the structure into the base structure of the button base and turning it, they can be fitted together and the button body can be easily attached to the button base.
In addition, according to the replaceable button of the present invention, the button body can be made of plastic and can be integrally molded, and can be manufactured by the conventional button molding technology. be able to.
Furthermore, according to the replaceable button of the present invention, the button can be attached to the button base with respect to the button base, and if the button base is correctly attached to the clothes, the button main body is in the correct posture. It can be attached with.

Hereinafter, embodiments of replaceable buttons according to the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to those shown in the following examples.
As a configuration example of the replaceable button 100 of the present invention, the combination of the base structure of the button base and the main body structure of the button main body is the first type in which the former is a so-called male and the latter is a so-called female. Is a so-called female and the latter is a so-called male second type. Further, even in the second type, there can be a first pattern and a second pattern.
Hereinafter, a first type will be described as Example 1, a second type of first pattern will be described as Example 2, and a second type of second pattern will be described as Example 3.

A configuration example of the replaceable button 100 according to the first embodiment of the present invention will be described.
In the first embodiment, the base structure of the button base 110 is a so-called male and the main body structure of the button main body 120 is a so-called female combination.
The replaceable button 100 according to the present invention has a basic structure including, for example, a button base 110 and a button body 120 as shown in FIGS. 1 and 2. These are examples of the basic structure of the first type. Even if the structure and function of these components are improved and different, they can be replaced with other components different from these components. Even a button is included in the technical scope as long as it has the basic structure of the replaceable button of the present invention.

FIG. 1 is a diagram illustrating the basic structure of the button base 110 of the replaceable buttons 100 of the present invention very simply. The top view, the bottom view, the front view, the right side view, the AA line sectional view, the BB line sectional view, and the CC line sectional view are shown.
FIG. 2 is a diagram showing the basic structure of the button body 120 of the replaceable button 100 of the present invention very simply. The top view, bottom view, front view, right side view, DD line sectional view, and EE line sectional view are shown. The button top itself is not shown.

  The replaceable button 100 according to the present invention has a basic structure including, for example, a button base 110 and a button body 120 as shown in FIGS. 1 and 2. These are examples of the basic structure of the first type. Even if the structure and function of these components are improved and different, they can be replaced with other components different from these components. Even a button is included in the technical scope as long as it has the basic structure of the replaceable button of the present invention.

  The button base 110 is a member that is previously sewn to a predetermined button attachment position via a thread. As shown in FIG. 1, a base 111, a threading hole 112, a threading hole groove 113, a locking rod 114, a long side 114-1 of the locking rod, and a short side 114-2 of the locking rod are provided. It becomes the composition.

In the example of FIG. 1, the base 111 is rectangular and has rounded corners. However, the outer size of the base 111 is not limited as long as it can be received by the hole 123 of the button body described later. The basic shape may be a disk shape or a rectangular shape.
In this configuration example, the button base 111 has a substantially rectangular cross section. Of the two corners on the diagonal line, one corner is rounded to shorten the distance from the rotation axis. And one corner is a long-range angle with a large distance from the rotation axis without rounding. As will be described later, this device has a contact structure for braking the rotational movement of the button body 120 with the button body 120 attached to the button base 110. In the rotational movement of the lock receiving portion 122 of the button main body 120, the rotation trajectory of the structure whose rotation trajectory is on the innermost side (the short side 122-2 of the lock receiving portion described later in this example) is the short-range angle. A contact structure is obtained by adjusting the long distance angle so as not to contact. This contact will be described later.

  The threading hole 112 is a through hole provided in the base 111. In this configuration example, the threading hole 112 is a hole that penetrates the base 111 and the locking rod 114. In this configuration example, four holes are provided. It is a configuration example. The arrangement of the threading holes 112 is not particularly limited, but it is preferable to arrange the threading holes 112 on the base 111 in a balanced manner in order to support the base 111 evenly. A shank may be used as long as the base 111 is securely attached to the clothes 300, but here, a threading hole is used.

  The threading hole groove 113 is a groove provided so as to connect between the threading holes 112 as shown in the sectional view taken along the line B-B in FIG. 1, and the thread bundle passed through the threading hole 112 It is a groove that enters when it passes through the surface side of the button base, so that the thread does not rise on the surface but fits under the surface of the button base. As will be described later, when the button base 110 and the button main body 120 are fitted to each other, the gap between the two can be prevented from floating due to the yarn bundle.

  The locking rod 114 is a base structure provided on the base 111, and is a hook-like structure having a long side 114-1 and a short side 114-2. At least the long side 114-1 is longer than the diameter of the base 111 and protrudes outward from the base 111. In this configuration example, the locking bar 114 is an example provided on the upper surface of the base 111, but it need not necessarily be the upper surface of the base 111 and may be a side surface of the base 111. The height at which the locking rod 114 is provided is not limited, but is a height corresponding to a slit portion 124 described later.

As will be described later, the shape of the locking rod 114 is fitted to the slit portion 124, so that it can be fitted to the slit portion 124. In this configuration example, the upper and lower sides of the disk are cut off. That is, in the configuration example of FIG. 1, the left and right portions that are not cut off in the disc form the long side 114-1, and the up and down portion that is cut off in the disc forms the short side 114-2. It has become a thing. Note that the center of the locking rod 114 substantially coincides with a rotation axis when the button body 120 described later rotates.
The material of the button base 110 having these configurations is not limited, but it may be integrally molded with a plastic material.

Next, the button body 120 will be described.
The button main body 120 is provided with a button top on the surface, includes a button main body structure for fitting with the button base 110, and is supported by being combined with the button base 110. By replacing the button body 120, the button top can be easily and freely replaced.
As shown in FIG. 2, the button main body 120 has a configuration including a lock receiving portion 122, a hole portion 123, and a slit portion 124, which become a button main body structure, in addition to the button top base 121.

  The button top base 121 is a portion to which a button top that is a decoration of the button 100 is attached. Although the button top is not shown in FIG. 2, the button top is provided on the button top base 121. The button top may have various shapes, patterns, colors, and the like, and is a portion that can be seen on the front surface when the button 100 is attached to the clothing 300. It may be planar or a three-dimensional shape. That is, the button top to be attached to the button top 121 can have various shapes depending on the design, and various patterns and designs are drawn depending on the design.

  The lock receiving portion 122 forming a part of the button body structure is a cylindrical member erected on the back surface of the button top 121 and has a cross-sectional shape that can receive the lock rod 114 of the button base 110. Is. In this configuration example, the shape of the latch receiving portion 122 is such that the top and bottom of the cylinder are cut off corresponding to the latch rod 114. That is, in the configuration example of FIG. 1, the left-right portion that is not cut off in the cylinder forms the long side portion 122-1, and the up-down portion that is cut off in the cylinder forms the short side portion 122-2. It has become a thing.

Here, the long side portion 122-1 forms a part of a cylinder. In this cylinder, the trajectory passing through the outermost periphery when the locking rod 114 rotates is the inner diameter of the cylinder. That is, as shown in FIG. 2, the trajectory of rotation of the corner portion of the locking rod 114 is a trajectory passing through the outermost periphery, but is a part of a cylinder having an inner diameter along the trajectory.
On the other hand, the short side portion 122-2 is shorter to be closer to the center than the long side portion 122-1, and is a straight line in the configuration example of FIG. A slit portion 124 is provided on the side surface of the latch receiving portion 122 of the short side portion 122-2, and the slit portion 124 receives the long side 114-1 of the latch rod 114. On the other hand, the short side portion 122-2 is a structure that comes into contact with the base 111 of the button base 110. As will be described later, in the rotational movement of the lock receiving portion, the short side portion 122-2, which is the structure having the innermost rotation locus, rounds the corner portion of the base 111 to reduce the distance from the rotation axis. It does not come into contact with the short-range angle, but does not round the corner portion, but comes into contact with the long-range angle obtained by taking a large distance from the rotation axis.

The hole 123 is a recess provided in the center of the latch receiving portion 122. In this configuration example, it is a space for receiving the locking rod 114, and has a circular shape that is cut off in the vertical direction corresponding to the shape of the locking rod 114.
The long side portion 123-1 of the hole corresponds to the long side portion 114-1 of the locking rod, and even when the locking rod 114 rotates, the outermost rotation locus (that is, the long side portion 114- of the locking rod). 1 rotation trajectory).
The short side portion 123-2 of the hole portion is shortened corresponding to the short side portion 114-2 of the locking rod, but the short side portion 123-2 of the hole portion is directly connected to the slit portion 124, It can be said that the short side portion 123-2 of the hole is opened outward through the slit portion 124.

  The slit portion 124 is a slit provided on the side surface of the short side portion 114-2 of the latch receiving portion 114, and is directly connected to the short side portion 123-2 of the hole portion. The width of the slit 124 is a width that can accept the thickness of the locking rod 114, and as will be described later, the long side portion 114 of the locking rod of the button base 110 that is not moved by the rotation of the button body 120. When -1 protrudes from the short side portion 122-2 of the locking receiving portion, the slit portion 124 provides a space for receiving the locking rod 114. Due to the presence of the slit portion 124, even if the button base locking rod 114 is stationary and the button main body 120 rotates, the locking receiving portion 122 can rotate along the locking rod 114.

FIG. 3A shows the button main body 120 in a horizontal end view cut at a height where the slit portion 124 is provided so that the internal structure can be easily understood. FIG. 3B is a diagram showing the bottom surface portion of the latch receiving portion 124 as an end surface.
In FIG. 3, the cut end face is hatched. A hatched portion is a portion where the latch receiving portion 122 exists, and a non-hatched portion is a slit portion 124. That is, the long side portion 122-1 on the left and right sides of the latch receiving portion 122 is an end face, but the area where the slit portion 124 is provided is a space and is not hatched. On the other hand, as can be seen from the hatching of the bottom surface portion of the locking receiving portion 124 in FIG. 3B, the locking receiving portion 124 itself is provided to circulate.
The material of the button body 120 having the above-described configuration is not limited, but may be integrally molded with a plastic material.

Next, an example of attaching the button body 120 to the button base 110 will be described with reference to FIGS.
FIG. 4 is a diagram showing how the button body 120 is inserted into the button base 110.
On the left side of FIG. 4, a plan view is depicted as seen from above. The button body 120 does not show the lower structure when viewed from the top, but here, the button body 120 is drawn in a state in which the lower structure is transparent so that the internal structure of the button body 120 and the position of the slit can be easily understood. . Further, the button body 120 is shown in an end view cut at the height of the slit 124. A hatched portion is a portion where the latch receiving portion 122 exists, and a non-hatched portion is a slit portion 124.
Further, on the right side of FIG. 4, a bottom view is drawn as seen from the bottom surface. In order to make the state of contact easy to understand, the right side of FIG. 4 is hatched with the bottom surface portion of the latch receiving portion 122 as an end surface, as in FIG.
FIG. 5 is a diagram illustrating a state in which the button main body 120 inserted into the button base 110 is rotated. The illustrated method is the same as in FIG.

First, as shown in FIG. 4A to FIG. 4B, while the locking receiving portion 122 of the button main body 120 is applied to the locking rod 114 of the button base 110, The locking rod 114 is inserted into the space of the hole 123 of the button body 120. The inner edge of the latch receiving portion 122, that is, the shape of the hole portion 123 corresponds to the shape of the latch rod 114 and is smoothly inserted.
FIG. 4B shows an initial state before the rotation with the button body 120 inserted into the button base 110. After obtaining the state of FIG. 4 (b), it is rotated.

FIG. 5 is a diagram for explaining the relationship between the slit portion 124 and the locking rod 114 and the contact between the base 111 and the locking receiving portion 122 during rotation.
As shown in FIG. 5 (a), the locking rod 114 is inserted in alignment with the long side portion 123-1 of the hole 123 with the long side portion 114-1 in the horizontal direction as a state before rotation. In this state, there is no part where it abuts anywhere.
From the state of FIG. 5A, the button body 120 is rotated as shown in FIGS. 5B and 5C. In this example, it is turned in the direction of the right screw, that is, clockwise. Since the left side is a view from the top, clockwise rotation is drawn as a clockwise rotation, and since the left side is a view from the bottom, clockwise rotation is drawn as a counterclockwise rotation. ing.

Here, the inner diameter R <b> 2 of the latch receiving portion 122 is slightly larger than the diameter R <b> 1 of the long side portion 114-1 of the latch rod 114, and the latch rod 114 is inserted into the latch receiver 122. In this state, the entire button body 120 rotates.
As shown in FIG. 5B, when the button body 120 is rotated clockwise, the locking rod 114 of the button base 110 does not move, but the button body 120 changes its angle. The long side portion 114-1 of the locking rod 114 protrudes outward beyond the locking receiving portion 122. However, since the slit portion 124 exists, the long side portion 114-1 of the locking rod 114 protrudes outward as it is. it can. That is, in this state, there is no part that is in contact with anything. On the other hand, the base 111 rotates and comes close to the edge of the short side 122-2 of the latch receiving portion. Of the corners of the base 111, the corner immediately in the rotation direction is the short side 122 of the latch receiving portion. Since it is rounded so as not to collide with -2, there is no problem in rotation.

Next, as shown in FIG. 5C, when the button main body 120 is further rotated clockwise to approximately 90 degrees, all the long side portions 114-1 of the locking rod enter the slit portion 124. On the other hand, the base 111 is in a state in which the corner portion whose corner is not rounded is in contact with the short side 122-2 of the lock receiving portion. Here, the button body 120 is further rotated clockwise (counterclockwise in the bottom view). ) Will not rotate. In this way, when the contact state shown in FIG. 5C is reached, the rotational movement of the button main body 120 is braked by the base 111 of the button base 110 and the short side 122-2 of the locking receiving portion of the button main body 120. This is the end of the rotational movement.
The state shown in FIG. 5C is a steady state in which the button body 120 is attached to the button base 110.

  The above is the procedure for attaching the button body 120 to the button base 110. The user simply attaches the lock receiving portion 112, which is the button main body structure of the button main body 120, and the hole portion 123 to the locking rod 114, which is the base structure of the button base, and rotates the button main body 120. Can be supported stably. Moreover, about the removal procedure, it can carry out in the reverse procedure of the attachment procedure.

A configuration example of the replaceable button 200 according to the second embodiment of the present invention will be described.
The configuration of the replaceable button 200 according to the second embodiment is a configuration including a button base 210 and a button main body 220 as shown in FIGS. 6 and 7 as a basic structure. These are examples of the basic structure of the second type, and even if the structure and function of the components are improved and different, and can be replaced with other components different from these components. Even a button is included in the technical scope as long as it has the basic structure of the replaceable button of the present invention.

FIG. 6 is a diagram showing the basic structure of the button base 210 in the second type replaceable button 200 very simply.
FIG. 7 is a diagram showing the basic structure of the button body 220 of the second type replaceable button 200 very simply.

The button base 210 according to the second embodiment is a member that is previously sewn to a predetermined button attachment position via a thread. As shown in FIG. 6, the base 211, the threading hole 212, the groove 213, the hole 214, the edge of the hole 214, and the notch structure 215 that forms the notch around the edge and the notch structure 215 The contact body 216 raised up is provided.
Since the base 211, the threading hole 212, and the groove 213 may be the same as those in the first embodiment, description thereof is omitted here.

  The hole 214 is a hole provided in the base 211 and receives the column part 222 and the protrusion 223 of the protrusion structure of the button body 220. In this configuration example, the hole has a rectangular cross section. Although the arrangement of the hole 214 is not particularly limited, in order to attach the button main body 220 in a well-balanced manner, it is arranged near the center in this configuration example.

  The notch structure 215 is a member that forms the edge of the hole 214. In this configuration example, as shown in the bottom perspective view, the AA line cross-sectional view, and the CC line cross-sectional view of FIG. 6, the plate material surrounds the hole 214 near the center of the base 211. A hole 214 is provided in the center of the plate material, and a peripheral portion is a cutout structure 215.

  In this configuration example, the notch structure 215 of the button base 210 has a fan-like notch structure provided around the hole 214. The center of the fan is in the hole 214, and as will be described later, when the button body 220 rotates around the column part 222, the rotation locus of the protrusion 223 becomes a fan shape, but the notch structure 215 follows the rotation locus. It is equivalent. Therefore, as will be described later, after the protrusion structure of the button body 220 is inserted into the hole 214 of the button base 210, the protrusion 223 is cut through the notch structure 215 when the button body 220 rotates. It starts to rotate.

  As will be described later, the thickness D1 of the plate portion covering the notch surface of the notch structure 215 corresponds to the height D2 of the column portion 222 of the protrusion structure of the button body 220, and is slightly The height D2 of the column part is larger than the thickness D1 of the plate part of the cutout structure 215. Therefore, when the button main body 220 rotates, the plate portion of the notch structure 215 is adjusted so as to enter and be held in the gap between the protrusion 223 and the back surface of the button main body 220.

  The contact body 216 is a contact body structure having a thick wall provided in a part of the notch structure 215. In the example shown in FIG. 6, the thickness of the end portion of the cutout structure 215 is thick, and the protruding portion 223 of the button main body 220 comes into contact with and stops.

  The material of the button base 210 having these configurations is not limited, but may be integrally molded with a plastic material.

Next, the button body 220 will be described.
The button main body 220 is provided with a button top on the front surface and a protruding structure on the back surface, and is supported by being combined with the button base 210. By replacing the button body 220, the button top can be easily and freely replaced.
As shown in FIG. 7, the button main body 220 is configured to include a button top 221, a column part 222 serving as a protruding structure, and a protruding part 223.

  Since the button top 221 may be the same as that of the first embodiment, a description thereof is omitted here.

  A part of the column part 222 of the protruding structure is a member erected on the back surface of the button top 221 and has a cross-sectional shape that can be inserted into the hole 214 of the button base 210. In this configuration example, the shape is rectangular, and the size thereof can be inserted into the hole 214 of the button base 210.

  The protrusion 223 is a protrusion provided on a part of the column part 222. In this configuration example, the protruding portion 223 has a rod-like shape and is provided on both sides of the column portion 222. The shape of the protrusion 223 and the rotation trajectory around the pillar 222 correspond to the cutout structure 215 of the button base 210, and the protrusion structure of the button body 220 is a button as will be described later. Rotation is possible in the hole 214 of the base 210.

  It is preferable that the height D4 of the protrusion 223 corresponds to the notch depth D3 of the notch structure 215. If D4 ≦ D3, the button body 220 may be the column portion with the protruding portion 223 inserted into the cutout structure 215 while the column portion 222 that is the protruding structure is inserted into the hole 214. It is possible to rotate around 222. Further, in a state where the button base 210 and the button main body 220 are fitted, the height D4 of the protrusion 223 does not match, and the fitted parts do not float.

  The material of the button body 220 having the above-described configuration is not limited, but may be integrally molded with a plastic material.

Next, an example of attaching the button body 220 to the button base 210 will be described with reference to FIGS.
FIG. 8 is a perspective view showing how the button body 220 is inserted into the button base 210.
FIG. 9 is a diagram illustrating a state in which the button main body 220 inserted into the button base 210 is rotated. On the left side of FIG. 9 (a) to FIG. 9 (c), a longitudinal sectional view corresponding to the cross section along the line DD shown in FIG. 8 is shown so that the internal structure of the button base 210 can be easily understood. Further, the button body 220 is shown in a side view so that the protruding structure can be easily understood. On the other hand, on the right side, a cross-sectional view taken along line E-E shown in FIG. 9A is shown so that it can be easily understood that the button main body 220 rotates while being combined with the button base 210.

  First, as shown in FIG. 8A to FIG. 8C, the column part 222 and the protrusion part 223, which are protrusion structures of the button body 220, are inserted into the hole part 214 of the button base 210. go. The shape of the hole 214 is a rectangle, and the shapes of the pillar 222 and the protrusion 223 are also corresponding to the rectangle. The pillar 222 and the protrusion 223 are smaller, so that they can be inserted smoothly.

  Here, the state of FIG. 9A is a state in which the button main body 220 is inserted into the button base 210 as shown in FIG. 8C.

From the state of FIG. 4A, the button body 220 is rotated as shown in FIGS. 9B and 9C. In this example, it is turned in the direction of the right screw, that is, clockwise.
Here, the height D2 of the column portion is slightly larger than the thickness D1 of the plate portion of the notch structure 215, and the protruding structure is inserted into the button base 210 in the entire button body 220. Rotates. At this time, the protrusion 223 rotates while being smoothly received in the notch structure 215.

  As shown on the right side of FIG. 9B, the protrusion 223 rotates clockwise (clockwise). Note that, as shown on the left side of FIG. 9B, the plate portion of the notch structure 215 is fitted by a gap between the protrusion 223 and the back surface of the button main body 220.

Next, as shown on the right side of FIG. 9C, when the protruding portion 223 of the protruding button body protruding structure comes into contact with the contact body 216, the rotation stops. In this example, the protrusion 223 contacts the contact body 216 in a state rotated 90 degrees.
As shown on the left side of FIG. 9C, the plate portion of the notch structure 215 is fitted by a gap between the protrusion 223 and the back surface of the button body 220, and both are stable. Stay in the state.

  The above is the procedure for attaching the button body 220 to the button base 210. The user can simply attach the column 222 and the protrusion 223, which are the protrusion structures of the button body 220, to the hole 214 of the button base 210 and rotate them, and can support them stably. Moreover, about the removal procedure, it can carry out in the reverse procedure of the attachment procedure.

As the replaceable button 200a of the present invention according to the third embodiment, the fitting portion is spiraled so as not to be easily reversely rotated so as to increase the stability in the mounting posture of the button body 220a to the button base 210a. An example of a configuration with is shown.
This device can be applied to either the first type shown in the first embodiment or the second type shown in the second embodiment. Here, application in the configuration example of the second type of the second embodiment is taken as an example. A configuration in which the fitting portion is provided with a spiral is also possible in the type of the first embodiment.

FIG. 10 is a diagram showing the basic structure of the button base 210a out of the replaceable buttons 200a according to the third embodiment in a very simple manner. Of the replaceable buttons 200a of the third embodiment, the button body 220a may have the same configuration as that of the second embodiment, and is not shown here.
Note that these are examples of the basic structure, and even if the mechanisms and functions of these components are improved and different, they are replaceable buttons to which other components different from these components are added. May be.

  As shown in FIG. 10, the button base 210a includes a base 211a, a threading hole 212a, a groove 213a, a hole 214a, a notch structure 215a, and a contact body 216a, as in the second embodiment. However, in the configuration of the second embodiment, as clearly illustrated in the cross-sectional view taken along the line H-H in FIG. 10, the plate portion serving as the cut-out surface of the cut-out structure 215 a is the button base. In this structure, a spiral is provided around the central axis of 210a. The method of winding the spiral is not limited, but in this example, the spiral is wound in a clockwise manner.

  As described above, since the plate portion of the notch structure 215a has a spiral inclination, the gap between the protrusion 223a of the button body 220a and the back surface of the button body 220a sandwiches the plate portion of the notch structure 215a. However, when rotating along the surface of the plate portion of the notch structure 215a, the screwing proceeds slightly, and the button main body 220a rotates while being tightened in the direction approaching the button base 210a.

  Next, as in the first embodiment, the button main body 220a is configured to include a button top 221a, a pillar 222a serving as a protrusion structure, and a protrusion 223a provided on a part of the pillar 222. The same configuration as in Example 1 may be used.

FIG. 11 is a diagram illustrating a state in which the button main body 220a inserted into the button base 210a is rotated. It is shown in a direction rotated by 90 degrees compared to FIG.
On the left side of FIGS. 11 (a) to 11 (c), a vertical cross-sectional view corresponding to the cross section taken along line HH in FIG. 10 is shown so that the internal structure of the button base 210a can be easily understood. 220a is a side view for easy understanding of the protruding structure. On the other hand, on the right side, a cross-sectional view taken along the line I-I shown in FIG. 11A is shown so that it can be easily understood that the button main body 220a rotates while being combined with the button base 210a.

  As shown in FIG. 11A to FIG. 11B, in the procedure for attaching the button main body 220a to the button base 210a of the second embodiment, the protrusion 223a of the button main body 220a and the back surface of the button main body 220a When the plate portion of the cutout structure 215a is sandwiched by the gap and rotates along the surface of the plate portion, the plate portion has a slight spiral, so that the screwing proceeds, and the button body 220a is moved to the button. It is tightened in a direction approaching the base 210a. When the projection body 223a advances while being screwed by the rotation of the button body 220, it eventually comes into contact with the contact body 216a.

  As described above, if a spiral inclination is provided in the plate portion of the cutout structure 215a, the projection 223a of the button main body 220a and the button main body 220a as shown in FIGS. 11 (b) to 11 (c). If the plate portion of the notch structure 215a is rotated while being pinched by a gap with the back surface of the button body 220a, the button body 220a is tightened in a direction approaching the button base 210a, and the plate portion of the notch structure 215a is slightly inclined. On the other hand, since the edge of the protrusion 223a remains horizontal and is pressed and pressed toward the surface of the plate portion of the cutout structure 215a, the inner surface of the protrusion 223a, particularly, as shown in FIG. As described above, a strong frictional force is generated at the portion in direct contact with the notch structure 215a, and the button body 220a is attached to the button base 210a. Stability increases in attached position, the easier it can be fixed so as not to reverse rotation. It cannot be easily removed in daily operations.

  In this way, if the plate portion that becomes the notch surface of the notch structure 215a has a structure in which a spiral is provided around the central axis of the button base 210a, a frictional force is generated. Stability increases when the button body 220a is attached to the button base 210a.

A configuration example of the replaceable button 200c according to the fourth embodiment of the present invention will be described.
FIG. 12 is a diagram showing the basic structure of the button base 210c very simply among the replaceable buttons 200c according to the fourth embodiment of the present invention.
FIG. 13 is a diagram showing the basic structure of the button main body 220c of the replaceable button 200c of the present invention according to the fourth embodiment very simply.

  As shown in FIGS. 12 and 13, the replaceable button 200c according to the fourth embodiment of the present invention has a basic structure including a button base 210c and a button main body 220c. These are examples of the basic structure of the second type of the replaceable buttons according to the present invention as described at the beginning of [Best Mode for Carrying Out the Invention]. Even if it is improved and different, or even if it is a replaceable button to which other components different from these components are added, the basic configuration of the replaceable button of the present invention is required. It is included in the technical scope.

As shown in FIG. 12, the button base 210c has a shape of the hole 214c and a notch that forms the edge of the hole 214c and a notch around the edge as compared to the button base 210 shown in the second embodiment. The shape of the structure 215c is different. The base 211c, the threading hole 212c, the groove 213c, and the like have substantially the same shape as each configuration of the button base 210 shown in the first embodiment.
Here, the hole 214c and the cutout structure 215c will be described, and descriptions of the base 211c, the threading hole 212c, the groove 213c, and the like similar to those of the first embodiment will be omitted as appropriate.
In FIG. 12, a plan view, a rear view, and a right side view are shown. Further, a cross-sectional view taken along line OO and a cross-sectional view taken along line NN in the plan view are also shown.

  The hole 214c penetrates from the top surface to the back surface of the button base 210c as in the second embodiment. However, the hole portion 214c does not necessarily penetrate to the back surface, and may be in a state where a so-called lid is provided on the back surface.

  The shape of the hole 214c is long in the up-down direction and short in the left-right direction in FIG. As will be described later, when the protrusion 223c of the button main body 220c is inserted into the hole 214c of the button base 210c from the upper surface, the long portion of the protrusion 223c can pass through in the vertical direction, otherwise If the button main body 220c is rotated and the protrusion 223c is rotated as will be described later, the longer portion of the protrusion 223c is changed. As long as the button body 220c is not positioned in the up-down direction, the effect that the button body 220c does not come out of the button base 210c is exhibited.

As shown in FIG. 12, the notch structure 215c is provided outwardly on the back surface side of the button base 210c among the edges of the hole 214c, and its contour line has a plurality of recesses in a circular arc shape. And the convex part is repeated. The notch structure 215c is not provided on the upper surface side of the button base 210c so that the notch structure 215c can be easily seen in the rear view and the OO line cross-sectional view. Once the protruding portion 223c is fitted into the cutout structure 215c, it does not come out to the upper surface side.
In the example of FIG. 12, the edges of the cutout structure 215 c are provided on the left and right sides and are wavy, but are contours that are point-symmetric with respect to the center point.

Next, the button body 220c will be described.
As shown in FIG. 13, the button main body 220c has a structure including a button top 221c, a column portion 222c, and a protrusion 223c.

  The button top 221c is a decorative plate for the button 200c as in the first embodiment, and may have various shapes, patterns, colors, and the like.

  The column part 222c is a member erected on the back surface of the button top 221c, and has a cross-sectional shape that can be inserted into the hole part 214c of the button base 210c. In this configuration example, the shape is rectangular, and the size thereof can be inserted into the hole 214c of the button base 210c. As will be described later, even if the button main body 220c is rotated with respect to the button base 210c, the column portion 222c does not collide with the hole 214c or the notch structure 215c.

The protrusion 223c is a protrusion provided on a part of the pillar 222c. The diameter of the protruding portion 223c is larger than the diameter of the column portion 222c.
In the configuration example of FIG. 13, the contour line of the shape of the protrusion 223 c is a curve, and in the state illustrated in the plan view of FIG. 13, the vertical direction is the longest and the diameter is small in the horizontal direction. Therefore, only when the shape of the protrusion 223c of the button body 220c is vertically long as shown in the rear view of FIG. 13, as shown in the rear view of FIG. 215c can be inserted into the button base 210c which is long in the vertical direction.

FIG. 14 is a diagram illustrating a state in which the button main body 220c is inserted into the button base 210c from the upper surface and a state in which the button main body 220c is rotated after the insertion.
As described above, the hole 214c and the notch structure 215c are long in the vertical direction only when the shape of the protrusion 223c of the button main body 220c is in a position that is long in the vertical direction as shown in the rear view of FIG. The button base 210c can be inserted.

  The height of the protrusion 223c corresponds to the depth of the notch structure 215c. As shown in FIG. 14B, the protrusion 223c is inserted in the state where the pillar 222c is inserted into the hole 214c. Enters the cutout structure 215c, and the button body 220 can be rotated around the column portion 222.

Here, a mechanism in which the protrusion 223c can be fitted in the cutout structure 215c in the fourth embodiment will be described.
Since the projecting portion 223 has a part of the tip that is long in the outward direction, the tip of the projection 223 fits into the recess of the cutout structure 215c. Here, if the arc locus drawn by the tip of the projecting portion 223c is outside the arc connecting the convex portions of the outline of the notch structure 215c and inside the arc connecting the concave portions, Since the tip fits into one of the recesses of the notch structure 215c and the protrusions of the notch structure 215c exist on both sides thereof, the rotational position of the button body 220c is stabilized.

  FIG. 15 is a diagram showing from the back side how the protruding structure 223c is fitted in the notch structure 215c when rotated in a state where the protruding structure 223c is inserted into the hole 214c of the button base 210c. In FIG. 15, the protruding structure 223 c is hatched so that the movement of the protruding structure 223 c can be easily understood.

  When the button main body 220c is rotated from the position shown in FIG. 15B, the tip of the projection 223c fits into the recess of the notch structure 215c in any of the states shown in FIGS. 15C, 15D, and 15E. It stabilizes at. The button main body 220c can be locked to the button base 210c by repeatedly fitting while the tip of the protrusion 223c moves from the concave portion of the notch structure 215c to the next concave portion, so-called “click”. .

  In this example, the tip of the protrusion 223c of the button body 220c is provided at two positions facing each other across the column 222c, while the recess of the notch structure 215c of the button base 210c also rotates. Since they are arranged symmetrically with respect to the center point and located on the circumference, the tip of the protrusion 223c is located at two locations on the left and right as shown in any of FIGS. 15 (c), 15 (d) and 15 (e). Since they are simultaneously fitted, the holding posture is further stabilized.

  Although the preferred embodiment of the replaceable button configuration example of the present invention has been illustrated and described above, it should be understood that various modifications can be made without departing from the technical scope of the present invention. Let's go.
