Description

  The present invention relates to a multi-axis hinge.

  Conventionally, a hinge is used to suspend a door from a frame so that it can rotate freely. An axis and a shaft insertion part are provided at the ends of two plate-like blades, and the axis of one blade is provided. Through the shaft insertion part of the other blade, and both are rotatably connected, and by fixing both blades separately to the door and the frame, the door can be opened and closed with respect to the frame. . The hinge frame is attached to the door and the door is characterized in that the shaft portion including the shaft center and the shaft insertion portion is taken out from the door surface and protrudes. It is possible to rotate it.

  However, since the shaft portion is taken out, the shaft portion protrudes from a relatively flat surface, and the protruding portion of the shaft portion is very undesirable in terms of design. Furthermore, the hinges are usually placed at two locations above and below the door, so the lower hinge's shaft part position is inevitably placed at the height of the head of an infant, etc. There is also a risk of hitting. Therefore, a hinge in which the shaft portion does not protrude from the door surface is desired.

  Therefore, a hidden hinge having a plurality of axial centers that can be opened up to 180 degrees without taking out the shaft portion is arranged in a state where it is dug into both the inner surface of the vertical frame and the door bottom surface of the door. Yes, a plurality of substantially triangular connecting plates are stacked and assembled with a plurality of pins, and the pins are folded while being slid along a predetermined groove. Hidden hinges having this basic structure are already known, and many improvements are disclosed in Japanese Patent Laid-Open Nos. 06-185252, 06-288139, 2002-121955, and the like.

  As another configuration, the hinge blades are connected in advance so as to be freely rotatable with two shaft centers, and one of the two shaft centers becomes the center of rotation while changing with a rule. As shown in FIG. 11, by the inventor of the present invention shown in FIG. 11, the rotation trajectory of the door is divided by 180 degrees, and first rotates around the first axis on the vertical frame side, and then switches. According to the rules, there is no malfunction by changing the axis that becomes the center of rotation from the closed state to the position near the predetermined angle and after that. A configuration for obtaining an opening / closing operation has been reported.

  In each of the above configurations, the door-side case and the frame-side case are always connected by blades. The frame-side case is dug in the vertical frame, and the door-side case is dug in the thickness direction of the door suspension side. It is built in and arranged. Therefore, one of the plurality of shaft centers is characterized in that it is always disposed in the vertical frame digging together with the frame side case. A part of the blade is also inserted into the frame side case when the door is completely closed. As a result, the thickness dimension of the vertical frame exceeding a certain level remains as a necessary condition. Furthermore, in the above configuration, the door bottom corner of the door inevitably becomes a trajectory approaching the vertical frame in the initial stage of opening the door, so it is still unsuitable for a large step between the vertical frame front and the door front. It is assumed that there is room for improvement.

However, in recent doors with an emphasis on design, a slim appearance with a very thin vertical frame is preferred, and the above-mentioned multi-axis concealed hinge needs to be compatible with a thin frame, and when opened, There is a demand for a configuration having an opening / closing locus that largely encircles the vertical frame without the door and the vertical frame approaching each other.
JP 06-185252 A JP 06-288139 A JP 2002-121955 A JP2007-211577

  The present invention has been made to solve the above-mentioned problems, and is a two-axis type hinge that hardly requires digging of the vertical frame, and can be opened up to 180 degrees by a regular opening / closing operation. When the door is closed, the entire hinge including the shaft center does not protrude from the door surface at all, and a hinge having a locus that can open and close the door while largely bypassing the front corner of the vertical frame is provided. Objective.

  In the present invention, the following technical means are provided to solve the above problems. First, a substantially box-shaped frame side case and a door side case are provided. The hinge blade is substantially U-shaped or curved when viewed from above, and is provided with a first axial insertion hole and a second axial insertion hole on the upper and lower surfaces of both ends, and a rotating cam shaft insertion hole between them. Arrange it. Then, a rotating cam having a fulcrum is provided near the center, and the engaging pin is mounted in a protruding state at both tip portions sandwiching the fulcrum. And it arrange | positions so that a rotation cam may be covered on each of the upper and lower sides of a blade | wing, and it assembles | attaches with a rotation cam shaft.

  Next, the frame side guide member and the door side guide member are attached to the frame side case and the door side case, respectively. At the shaft center, the door side case and the blade are connected by the second shaft center. Then, an opening / closing mechanism portion of a multi-axis hinge that opens and closes with a certain regularity is formed. In the present invention, the entire opening / closing mechanism portion is arranged in the thickness direction of the door on the door end side from the inner surface of the vertical frame. In other words, the frame-side case is mounted on the inner surface of the vertical frame in a substantially imposition manner, and the door bottom side thickness direction surface of the door is dug so that the entire opening / closing mechanism portion can be arranged inside the door as much as possible.

  However, since the opening / closing mechanism portion and the door surface must not come into contact with each other in the opening / closing operation of the door, it is necessary to partially cut out the front surface of the door. In terms of design, it is naturally better to have fewer notches on the front of the door. Therefore, the cut-out shape on the front of the door is the smallest so that the door-side case can be inserted with the door surfaces on both sides left in the deeply drilled position on the door. The door contact surface side is left, and only the front side is dug in a shape cut out in the vertical direction, and the frame side case is formed in this shallow portion. Then, when the door is closed, only the front of the frame side case is exposed in a state flush with the front of the door, and when a flat decorative cover is attached to this exposed part, the door is closed when the door is closed. A vertically long thin decorative cover with a certain width can be seen in the state of being flush with the door surface in the vicinity of the upper and lower ends of the front of the door.

  And by setting the opening / closing mechanism part in this arrangement, the door opening operation is first performed around the first axis, and the door front corner of the door passes through the inner surface of the vertical frame. Later, after approaching the 90 ° open position, the trajectory opens around the second axis, and at this stage, the door has already been opened by the distance between the first axis and the second axis. As a result, a trajectory that moves largely around the front corner of the vertical frame is obtained. As a result, even if the gap between the front of the door and the front of the vertical frame is large, the doors can be sufficiently opened and closed without interfering with each other.

  Further, in this configuration, a state in which the frame side case is exposed from the dug portion of the door when the door is opened about 90 degrees can be obtained. Therefore, using this state, the vertical adjustment screw is provided on either the upper or lower surface of the frame side case in a substantially vertical direction, and the groove that is wider than the diameter of the vertical adjustment screw and narrower than the diameter of the head is attached to the frame side mounting plate. The frame side mounting plate is previously mounted on the vertical frame. Then, the entire opening / closing mechanism portion including the frame side case provided with the vertical adjustment screw is attached to the door. Then, it is possible to simply configure a door hanging mechanism by an operation of hooking the vertical adjustment screw on the groove of the frame side mounting plate and an vertical adjustment mechanism by an operation of turning the vertical adjustment screw.

  By digging deep in the thickness direction surface of the door bottom side of the door so that the hinge opening and closing mechanism part can be inserted into the door as much as possible, the opening and closing mechanism part almost needs to be dug into the vertical frame It can be paid with the imposition without doing. As a result, it is possible to attach to a very thin vertical frame.

  The door side case is set so that it can be inserted in a state where both door surfaces are left at a deep position where the door is dug. The door contact surface side of the door at the shallow position is left, and only the front is cut out in the vertical direction. By digging in the shape, when the door is closed, only the front surface of the frame side case can be exposed so as to be flush with the front surface of the door. And by attaching a decorative cover to this exposed part, when the door is closed, it is possible to make the appearance excellent in design so that only a vertically long thin decorative cover with a certain width can be seen above and below the front end of the suspension side. it can.

  By disposing the opening / closing mechanism part in a substantially impositioned manner on the vertical frame, the door opening operation that opens first about the first axis is obtained, and then the center is opened about the second axis. At this stage, the door has already been taken out by a distance corresponding to the distance between the first axis and the second axis, and a trajectory is obtained in which the door surface largely moves around the front side of the vertical frame. Therefore, even if the level difference between the front of the door and the front of the vertical frame is large, an opening / closing operation with a margin can be obtained without contact between the two.

  Since the frame-side case is exposed from the digging portion of the door with the door opened slightly less than 90 degrees, vertical adjustment screws are provided on the upper and lower surfaces of the frame-side case in a substantially vertical direction to the frame-side mounting plate. With a simple configuration that only has a groove wider than the diameter of the vertical adjustment screw and narrower than the diameter of the head of the vertical adjustment screw, a suspension mechanism that moves the vertical adjustment screw in the groove and an operation to turn the vertical adjustment screw It is possible to implement an up-and-down adjustment mechanism.

It is an opening-and-closing locus | trajectory figure of the conventional hidden hinge.

  Embodiments of a multi-axis hinge relating to the present invention will be described below with reference to the drawings. The multi-axis hinge of the present invention is mounted at two places on the upper and lower sides of the door in the same way as a normal hinge and holds the door 29 on the vertical frame 28. Since it is substantially the same, it demonstrates in the structure of one side. FIG. 1 is a front view of the lower position of the door in a closed state, to which the multi-shaft hinge of the present invention is attached, and FIG. 2 is a top view of the same. FIG. 3 is an exploded perspective view showing the opening / closing mechanism portion a in a state of being disposed between the vertical frame 28 and the door 29.

  The opening / closing mechanism part a has substantially the same configuration as the hidden hinge shown in FIG. 11, and the frame side case 1, the door side case 2, the blade 3 and the rotating cam 4 are the main members as shown in FIG. The frame side case 1 is provided with a frame side guide member 5 having an arc-shaped elongated hole 9 composed of an arc portion 7 centering on the first axial insertion hole 6 shown in FIG. . The door-side case 2 is also provided with a door-side guide member 10 having an arc-shaped elongated hole 9 composed of an arc portion 7 centered on the second axial insertion hole 11 shown in FIG. deep. Further, a rotating cam 4 having tip portions on both sides with a rotating cam shaft insertion hole 12 serving as a fulcrum of the rotation operation as shown in FIG.

  Then, as shown in FIG. 3, the rotating cam shaft insertion hole 12 of the rotating cam 4 is rotatably mounted in a state of being inserted into the rotating cam shaft 14 of the blade 3. Therefore, the rotating cam 4 can rotate in the horizontal direction with respect to the blade 3. Next, the blade 3 fitted with the rotating cam 4 is assembled to the frame side case 1 and the door side case 2 by the first axis 15 and the second axis 16. The engaging pin 13 of the rotating cam 4 to be attached is in the arc-shaped elongated hole 9 of the frame side guide member 5 and the engaging pin 13 to be assembled to the door-side case 2 side is also the arc-shaped length of the door-side guide member 10. It is configured in a state of being inserted into the hole 9. Accordingly, in the vertical arrangement, the upper and lower surfaces of the rotating cam 4 are face-to-face with the frame-side guide member 5 and the door-side guide member 10 arranged on the upper and lower inner surfaces of the frame-side case 1 and the door-side case 2. Are arranged, and both the engaging pins 13 of the rotating cam 4 and both arc-shaped elongated holes 9 are arranged on the same horizontal plane, and the opening / closing mechanism portion a is configured as described above.

  Here, in order to clarify the shape, position, and direction of the digging into the door 29, the lateral digging of the door 29 in FIG. 2 is described as a deep position shallow position, and the surface of the door 29 is the back side. The door contact side 24 located at the front and the door front 23 located on the near side are described. Further, the thickness direction surface on the suspending side of the door 29 is referred to as a door bottom surface 21. Then, as shown in FIG. 2, the entire opening / closing mechanism part a is formed on the inner surface of the vertical frame in a state where a digging is formed from the door bottom surface 21 of the door 29 and the frame side case 1 is mounted on the inner surface 22 of the vertical frame. 22 in the thickness direction of the door 29 on the door end side. That is, it is preferable that only the door 29 is dug so that the entire opening / closing mechanism portion a can be arranged inside the door 29 as much as possible. However, since the door 29 and the opening / closing mechanism part a must not come into contact with each other in the opening / closing operation of the door 29, it is necessary to cut out the front part 23 of the door. In terms of design, it is naturally assumed that the door front 23 should have as few cutouts as possible.

  Therefore, as the cutout shape of the least door front surface 23, as shown in FIGS. 2 and 7, the door surfaces on both sides have a certain thickness at the deepest position of the digging formed from the door bottom surface 21 of the door 29. The door-side case 2 is formed so that it can be fitted and attached in the state of being left, and in the shallow position close to the door bottom surface 21, all the door-contacting side surfaces 24 of the door 29 are left, and only the front surface 23 is cut out in the vertical direction. The dug shape is optimal. And it forms so that the frame side case 1 may be arrange | positioned in this shallow position. Then, when the door 29 is closed, only the front surface of the frame side case 1 is exposed in a state flush with the door front surface 23, and a flat decorative cover 17 may be attached to the exposed portion.

  In addition, since the opening / closing mechanism portion a is configured such that the blade 3 that is long in the vertical direction enters and exits from the frame side case 1 and the door side case 2, the exposed portion of the frame side case 1 is a vertically long rectangle as shown in FIG. As a result, when the door 29 is closed, the appearance is such that the decorative cover 17 having a narrow width is visible above and below the front end of the suspension side. Further, there is no particular limitation on the vertical position of the dug, and the upper and lower ends of the door 29 are dug out as shown in FIG. 1 and FIG. A shape to be arranged and a shape to be arranged leaving the upper and lower ends of the door 29 as shown in FIG. 7B are possible. Then, the appearance of the door front 23 as a whole in the vertical direction on the suspending side changes considerably, and the design at the time of closing changes considerably, and the digging shape of FIG. 7 (b), but depending on the length of the upper and lower ends of the door 29, the image of a hinge without protruding parts is shown in FIG. 8 (b). New design shapes can be proposed for each. In addition, if it is important to be able to use the door 29 for both left and right, the door contact side surface 24 of the door 29 may be cut out as shown in FIG.

  Next, FIG. 9 shows the opening / closing locus of the door 29 from the closed state of the multiaxial hinge of the present invention. What is important here is the effect on the trajectory of the door 29 by arranging the opening / closing mechanism part a substantially impositioned so as to correspond to the thin vertical frame 28. Therefore, a comparison will be made with FIG. 11 which shows the locus of the door 29 in a conventional hidden hinge in which the frame-side case 1 is placed in the vertical frame 28 by digging a large amount into the vertical frame 28.

  9 and 11, the operation itself of the opening / closing mechanism part a is substantially the same. First, FIG. 9 (a) shows the closed state of the door 29, and the arcuate length of the frame side guide member 5 of the frame side case 1 is shown. An engagement pin 13 on one side of the rotating cam 4 is disposed at the end of the arc portion 7 of the hole 9, and the other engagement pin 13 is a bent portion of the arc-shaped elongated hole 9 of the door side guide member 10 of the door side case 2. 8 at the end. Accordingly, in the state of FIG. 9A, the door 29 is in a state in which it cannot rotate about the second axis 16. However, the blade 3 is rotatable with respect to the first axis 15 by the movement of the engaging pin 13 along the arcuate portion 7 of the frame side guide member 5. The center axis is opened around the first axis 15 until the vicinity of the predetermined angular position shown in FIG. 9C through FIG. 9B. 9C, the engaging pin 13 on the frame side case 1 side has moved to the intersection position side of the arc portion 7 and the bent portion 8. In FIG. Further, the engagement pin 13 on the door side case 2 side is also slightly moved from the end of the bent portion 8 to the intersecting position side.

  Further, when the door 29 is further opened from the state of FIG. 9C, the bent portion 8 on the door side case 2 side rotates the rotating cam 4 while pushing the engaging pin 13. Then, as shown in FIG. 9 (d), the interlocking pin 13 on the door-side case 2 side is pushed by the inclination of the bent portion 8 in conjunction with the operation of further releasing from the vicinity of the predetermined angular position, and the rotation cam 4 rotates. The movement to the crossing position with the arc portion 7 is performed simultaneously with the operation, and at the same time, the engagement pin 13 on the frame side case 1 side is inserted into the bent portion 8. That is, the switching mechanism as described above becomes possible by the rotation of the rotating cam 4 interlocked with the further opening operation of the door 29 from the vicinity of the predetermined angular position.

  When the door 29 is further opened, as shown in FIG. 9 (e), the engagement pin 13 on the door side case 2 side moves in the arc portion 7 of the door side guide member 10, and the rotation cam 4 The rotation operation is restricted again, and the engagement pin 13 on the frame side case 1 side can prevent the blade 3 from rotating in the returning direction around the first axis 15, thereby reliably avoiding the reverse folding phenomenon. It becomes possible to do. And the door 29 can be opened to the 180 degree | times open position shown in FIG.9 (f). In the operation of closing from the largely opened stage shown in FIG. 9 (f), what is the opening time when the engagement pin 13 on the door side case 2 side is pushed into the bent portion 8 from the arc portion 7 immediately before the vicinity of the predetermined angle position? The operation is reversed, the rotating cam 4 rotates in the returning direction, the engagement pin 13 on the frame side case 1 side moves from the bent portion 8 to the arc portion 7, and the first axis 15 of the blade 3 is centered. Therefore, the door 29 can be completely closed as it is.

  The basic operation of the opening / closing mechanism portion a is as described above. Here, in the conventional hidden hinge shown in FIG. 11, the first axis 15 is arranged at a deeply digging position of the vertical frame 28. 11B is a trajectory in which the door-side front corner 26 is extremely close to the vertical frame front corner 27. Accordingly, the step between the vertical frame front face 25 and the door front face 23 can only be used to fit in a very small step as shown in FIG. 11, and this point has been regarded as the biggest drawback of the hidden hinge having the above-described configuration. . However, in the locus in the arrangement of the present invention, as shown in FIG. 9, the first axis 15 is located closer to the door tip side than the inner surface 22 of the vertical frame, so that the door bottom front corner 26 is at the angle shown in FIG. In the vicinity, the vertical frame front face 25 is not approached at all, and after the approach to the 90 ° opening position shown in FIG. First, the operation of approaching the vertical frame front surface 25 is performed at the position in FIG.

  That is, in FIG. 9C and thereafter, the door 29 is opened around the second axis 16 after the door 29 is taken out by a distance corresponding to the distance between the first axis 15 and the second axis 16. Therefore, a trajectory that moves largely around the vertical frame front corner 27 is obtained. As a result, even if the level difference between the door front 23 and the vertical frame front 25 as shown in FIG. 9 is very large, the doors can be opened and closed with sufficient margin without interference. Furthermore, by arbitrarily setting the distance between the first axis 15 and the second axis 16, it is possible to cope with various steps between the door front surface 23 and the vertical frame front surface 25.

  Further, it is assumed that the multi-axis hinge of the present invention also requires a left / right / front / rear / up / down / up / down adjustment mechanism as in the prior art. Here, the multi-axis hinge of the present invention, the hidden hinge having the configuration shown in FIG. 11, and other configurations in which the frame-side case 1 and the door-side case 2 are built in the vertical frame 28 and the door 29 are also left and right. For the front-rear adjustment, a mechanism using an eccentric cam or a mechanism for pushing and pulling with an adjusting screw with the door 29 opened at about 90 degrees can be incorporated into both cases relatively easily. However, in the vertical adjustment, both cases are almost built-in with the conventional hidden hinge opened about 90 degrees, so a member with multiple inclined surfaces is incorporated inside the digging, and the horizontal direction of the adjustment screw etc. In many cases, it is necessary to have a configuration in which the movement in the horizontal direction is converted into the vertical direction by the operation from, and the cost remains high as an improvement.

  However, in the multi-axis hinge of the present invention, the frame side case 1 is exposed from the door 29 in the vicinity of the open position shown in FIG. Therefore, using this state, as shown in FIG. 10, the vertical adjustment screw 18 is screwed into the frame side case 1 in a substantially vertical direction, and is wider than the diameter of the vertical adjustment screw 18 and larger than the diameter of the head. A frame side mounting plate 19 having a narrow groove 20 may be provided and attached to the vertical frame 28 in advance. Then, the entire opening / closing mechanism portion a including the frame side case 1 provided with the vertical adjustment screw 18 is mounted on the door 29 in advance.

  Then, the door 29 is lifted at the time of construction of the door, and the hanging work by the operation of hooking the head of the vertical adjustment screw 18 on the groove 20 of the frame side mounting plate 19 becomes possible. Further, it is possible to easily carry out vertical adjustment by an operation of turning the vertical adjustment screw 18 thereafter. This configuration enables a direct vertical movement operation by the vertical adjustment screw 18, and as a result, it is a very simple component configuration with only the frame side mounting plate 19 and the vertical adjustment screw 18, so that it is very effective in terms of cost. It is done.
