Description

Plate-shaped foldable mouse

The present invention relates to a plate-shaped folding mouse, and more specifically, to a plate-shaped folding mouse having a thin plate shape, which is easy to store and carry when used with a laptop or pad.

Laptops and pads are easy to carry, making them very useful for people who go on business trips or work while on the move. Recently, as the number of people using them in schools, government offices, and coffee shops that have wireless communication facilities has increased, their distribution rate is increasing compared to desktop computers.

In particular, pads are rapidly increasing in use among people from children to the elderly due to their thinness and light weight. Pads are equipped with touchpads, so information is input by touching the screen, but in some cases, a mouse may need to be used.

However, since the mouse is much thicker than the pad or laptop, the mouse does not fit in the pad storage bag, so you have to store the mouse separately or buy a storage bag larger than the pad and store it together, which is inconvenient. In this case, the mouse also sticks out of the surface, which has the disadvantage of ruining the aesthetics.

Fig. 1 is a perspective view showing a state of storage of a plate-shaped folding mouse (100) according to the present invention, Fig. 2 is a perspective view showing a state folded during use, and Fig. 3 is an example view showing a state in which a user holds it with his or her hand for use.

The plate-shaped folding mouse (100) according to the present invention is provided with a mouse body (110) and a grip folding part (120) that are rotatably connected to each other. Accordingly, when not in use or when storing or carrying, the mouse body (110) and the grip folding part (120) are spread out horizontally and kept flat as shown in Fig. 1, and when used by connecting to a notebook or pad, the mouse body (110) and the grip folding part (120) are folded slanted by rotating them at a certain angle as shown in Fig. 2.

At this time, as shown in Fig. 3, the user can hold the folding part (120) with the hand (H) and operate the scroll wheel (130) using the thumb or operate the right button (113b) and the left button (113a).

To this end, it is preferable that the overall length (L) of the plate-shaped folding mouse (100) be smaller than the length of a typical adult's hand, so that it can be wrapped around an adult's hand when folded, as shown in Fig. 2.

The plate-shaped folding mouse (100) of the present invention is formed into a thin plate shape by unfolding the mouse body (110) and the grip folding part (120) when not in use. Accordingly, the user has the advantage of being able to store or carry it easily together with a pad or laptop, and when in use, it is folded so that the user can easily hold and operate it with their hand.

Figure 4 is an exploded perspective view showing the configuration of a plate-shaped folding mouse (100). As shown, the plate-shaped folding mouse (100) includes a mouse body (110), a grip folding part (120) rotatably connected to the mouse body (110), and a scroll wheel (130) provided on the mouse body (110) to move the screen by the user's rotation operation.

Here, the plate-shaped folding mouse (100) of the present invention may be equipped with a battery (140) and a communication means (not shown) for communication with a laptop or pad if it is wireless. The communication means (not shown) may be Bluetooth or communication using USB.

The mouse body (110) and the grip folding part (120) are each provided with a plate-like structure having a certain thickness (d) as illustrated in Fig. 1. At this time, the thickness (d) of the mouse body (110) and the grip folding part (120) is provided as a thin thickness in the range of 1 cm to 1.5 cm, so that they do not protrude to the outside even when stored together in a pad or notebook storage bag.

The mouse body (110) is provided with a configuration for implementing the functions of the mouse, and the grip folding part (120) is folded from the mouse body (110) to improve the grip feeling that allows the user to grip it with their hand.

The mouse body (110) includes a body base (111) with an open top, a body cover (113) covering the top of the body base (111), a main board (115) provided inside the body base (111), a light-emitting element (116) provided on a front ground contact slope (111b) of the body base (111), a reflective lens (117) provided on the lower part of the body cover (113), a light sensor (118) that receives light reflected from the reflective lens (117), and a left button sensor (119a) and a right button sensor (119b) that are operated by a left button (113a) and a right button (113b) of the body cover (113).

The main body base (111) is provided in a plate shape that is placed horizontally on the ground. A side wall (111a) of a certain height is formed in the border area of the main body base (111). The side wall (111a) determines the thickness of the mouse main body (110) at 1 to 1.5 cm.

At this time, a front ground contact slope (111b) is provided at the tip of the main body base (111) to be connected to the side wall (111a). As shown in (b) of Fig. 6, the front ground contact slope (111b) comes into contact with the ground or the mouse pad (G) when the mouse main body (110) and the grip folding part (120) are folded, and the light emitted from the light emitting element (116) is reflected, allowing the control unit (not shown) to recognize the position of the plate-shaped folding mouse (100).

It is preferable that the angle of inclination (θ) formed by the front ground contact slope (111b) and the main body base (111) correspond to the rotation angle (α) at which the mouse main body (110) and the grip folding part (120) are folded.

A pair of folding joint axes (112) are provided on both sides at the rear of the main body base (111), i.e., in the direction opposite to the front ground contact slope (111b). The folding joint axes (112) are coupled with the central rotation axis (125) of the grip folding part (120) to support the mouse main body (110) and the grip folding part (120) so that they rotate and fold with each other.

The folding joint shaft (112) is provided in a cylindrical shape and protrudes from the inner side of the side wall (111a) to a certain thickness. The outer diameter of the folding joint shaft (112) is provided to correspond to the thickness of the side wall (111a). A central rotation shaft (125) is coaxially coupled between a pair of folding joint shafts (112) to support each other so as to rotate. At this time, the folding joint shaft (112) and the central rotation shaft (125) are provided with a rotation angle limiting structure that limits the rotation angle of the mouse body (110) and the grip folding part (120).

As shown in an enlarged view in Fig. 4, a side rotation axis (112a) is provided to protrude in the central area of the inner wall surface of the folding joint shaft (112), and an angle limiting protrusion (112b) is provided to protrude in the edge area of the inner wall surface of the folding joint shaft (112) and spaced apart from the side rotation axis (112a).

In addition, on both sides of the central rotation axis (125), a rotation axis insertion hole (125a) into which a side rotation axis (112a) is inserted is provided in a sunken manner in the central region, and an angle adjustment slit (125b) into which an angle limiting projection (112b) is inserted is provided on the outer periphery of the rotation axis insertion hole (125a).

A side rotation shaft (112a) is inserted into the rotation shaft insertion hole (125a) to support the folding part (120) so that it can rotate and fold around the mouse body (110). The angle adjustment slit (125b) is formed in a recessed shape with an arc angle of 50 to 70°.

The angle adjustment slit (125b) limits the rotation angle so that the grip folding part (120) can be horizontally unfolded with respect to the mouse body (110) as shown in FIG. 1, or folded at a set angle as shown in FIG. 2. When the grip folding part (120) is unfolded horizontally as shown in FIG. 1, the angle limiting protrusion (112b) is supported by contact with the upper end of the angle adjustment slit (125b) to limit the grip folding part (120) from rotating any further.

In addition, as shown in Fig. 2, when the grip folding part (120) is folded for use, the angle limiting protrusion (112b) is supported by contact with the lower end of the angle adjustment slit (125b) to support the grip folding part (120) so that it does not rotate any further.

Even if the user holds and uses the plate-shaped folding mouse (100) in a folded state as shown in Fig. 3, the grip folding part (120) can be prevented from being arbitrarily unfolded or rotated to a larger angle by the structure of the angle adjustment slit (125b) and the angle limiting protrusion (112b).

In some cases, the outer wall surface of the side wall (111a) on which the folding joint axis (112) is formed may further be provided with a hook (not shown) or a catch (not shown) for fixing the angle in the folded state.

The main body cover (113) covers the upper part of the main body base (111) with an open upper part to prevent foreign substances from entering the interior. The main body cover (113) may be forcibly fitted between the side walls (111a) or may be fixed using a separate fastening member (not shown).

A left button (113a) and a right button (113b) are provided on both sides of the main body cover (113). The left button (113a) applies a signal to a left button sensor (119a) provided on the main board (115), and the right button (113b) applies a signal to a right button sensor (119b) provided on the main board (115).

Between the left button (113a) and the right button (113b), a wheel exposure hole (113c) is provided in the form of a long hole having a certain length along the longitudinal direction. The scroll wheel (130) is exposed to the outside through the wheel exposure hole (113c), so that the user can adjust the position of the screen by pushing or pulling the scroll wheel (130) with a finger.

The main board (115) is provided on the upper surface of the main body base (111). The main board (115) transmits input signals from the user through the left button (113a), right button (113b) and scroll wheel (130) and input signals by the movement of the plate-type folding mouse (100) to a notebook or pad. Although not shown in the drawing, the main board (115) is provided with a control unit (not shown) that determines the input signal and transmits it to the notebook or pad.

The main board (115) is supplied with power by a battery (140) in the case of wireless, and is supplied with power through a power supply line in the case of wired. The main board (115) is provided with a left button sensor (119a) and a right button sensor (119b) connected to a left button (113a) and a right button (113b).

Meanwhile, the mouse body (110) is equipped with a light-emitting element (116), a reflective lens (117), and a light sensor (118) for determining the positional movement of the plate-shaped folding mouse (100). Since the plate-shaped folding mouse (100) of the present invention is operated in a folded state, the light-emitting element (116) is positioned on the front ground contact slope (111b) that is positioned perpendicular to the ground.

As shown in an enlarged view in (b) of Fig. 6, the light emitting element (116) irradiates light (L) to the mouse pad (G) when the mouse body (110) and the gripping part (120) rotate and fold so that the front ground contact slope (111b) of the mouse body (110) touches the mouse pad (G). The light (L) irradiated to the mouse pad (G) is reflected from the surface of the mouse pad (G), then reflected by the reflective lens (117) and received by the light sensor (118).

A reflective lens (117) is provided on the inner wall surface of the main body cover (113) positioned vertically with the mouse pad (G), and a light sensor (118) is provided on one side of the scroll wheel (130). The positions of the reflective lens (117) and the light sensor (118) can be adjusted in consideration of the reflection path of the light (L).

The grip folding part (120) is rotatably connected to the rear end of the mouse body (110) and folds at a certain angle with the mouse body (110) to help the user easily grip it with his or her hand. It is preferable that the folding angle of the grip folding part (120) and the mouse body (110) be provided at an angle that allows the user to operate the scroll wheel (130) and the left button (113a) and the right button (113b) with the index finger while comfortably resting his or her hand. Accordingly, the folding angle (α) is preferably formed in the range of 50 to 70°.

In the present invention, the folding angle of the phage folding part (120) is limited to one angle by the angle limiting protrusion (112b) and the angle adjustment slit (125b), but may be adjusted to an angle that the user finds comfortable depending on the case.

The folding part (120) includes a folding base (121), a folding cover (123) covering the upper part of the folding base (121), and a central rotation shaft (125) provided at the front of the folding base (121) and rotatably connected to the mouse body (110) and the folding part coupling shaft (112).

The folding base (121) is provided in a plate shape having the same thickness as the main body base (111). The rear end of the folding base (121) is provided with a rear ground contact slope (121a) having the same inclination angle as the front ground contact slope (111b) described above. The rear ground contact slope (121a) comes into contact with the mouse pad (G) as shown in (b) of Fig. 6 and supports the plate-shaped folding mouse (100) to move along the ground.

The central rotation axis (125) is provided in a cylindrical shape protruding from the front of the folding base (121) and is connected to the folding joint axis (112) as described above.

If the plate-type folding mouse (100) is wireless, a holding plate (127) is provided inside the folding base (121), and a battery (140) can be detachably attached to the holding plate (127).

The scroll wheel (130) is provided on the mouse body (110) and is rotated by the user to adjust the position of the screen displayed on the notebook or pad. Here, the scroll wheel (130) of the present invention is provided in the form of an endless wheel to have a thickness corresponding to the thin thickness of the mouse body (110).

The scroll wheel of a conventional mouse is provided as a circular wheel. If such a circular scroll wheel is applied to the mouse body (110) of the present invention, it will protrude from the upper part of the mouse body (110), thus eliminating the meaning of providing the mouse body (110) in a plate shape.

Accordingly, a scroll wheel (130) in the form of an infinite track wheel is provided, so that it has a height almost corresponding to the mouse body (110) as shown in Fig. 1, so as not to affect the storage and carrying of the plate-type folding mouse (100).

Fig. 5 is a perspective view illustrating the configuration of a scroll wheel (130). As illustrated, the scroll wheel (130) includes a center wheel (131), front auxiliary wheels (133) and rear auxiliary wheels (134) provided in front and behind the center wheel (131), respectively, and an infinite track wheel (135) provided to surround the center wheel (131), the front auxiliary wheels (133), and the rear auxiliary wheels (134). The length of the infinite track wheel (135) is provided to correspond to the length of the wheel exposure hole (113c) of the main body cover (113), and the front auxiliary wheels (133) and the rear auxiliary wheels (134) are arranged in front and behind the wheel exposure hole (113c), and the center wheel (131) is provided in a rotatably central area.

As shown in (a) of Figure 6, the outer diameter of the center wheel (131), the front auxiliary wheel (133), and the rear auxiliary wheel (134) is formed to be 2 to 3 mm larger than the thickness of the mouse body (110), so that only the caterpillar wheel (135) is exposed through the wheel exposure hole (113c).

The center wheel (131) rotates around the wheel axle (131a), and a wheel encoder (136) that detects the rotational speed of the wheel axle (131a) is provided at one end of the wheel axle (131a), and a search sensor (137) is provided at the other end of the wheel axle (131a). The wheel axle (131a) is rotatably supported on a wheel axle support bracket (131b).

The front auxiliary wheel shaft (131a) of the front auxiliary wheel (133) and the rear auxiliary wheel shaft (131a) of the rear auxiliary wheel (134) are rotatably supported by the front wheel bracket (133b) and the rear wheel bracket (134b), respectively.

Since this scroll wheel (130) is provided in the form of an endless track wheel, it has the advantage of being able to accommodate the user's rotation operation while corresponding to the thin thickness of the mouse body (110).

The usage process of the plate-shaped folding mouse (100) of the present invention having such a configuration is explained with reference to FIGS. 1 to 6.

When the plate-type folding mouse (100) is not used, the mouse body (110) and the grip folding part (120) are stored horizontally unfolded as shown in FIG. 1. At this time, as shown in an enlarged view in FIG. 1, the side rotation axis (112a) of the folding part coupling shaft (112) is inserted into the rotation axis insertion hole (125a) of the central rotation axis (125), so that the grip folding part (120) is provided to be rotatable relative to the mouse body (110). In addition, the angle limiting protrusion (112b) is supported by contacting the top of the angle adjustment slit (125b), so that the grip folding part (120) can no longer rotate and can be maintained in the unfolded state.

This flat plate-shaped folding mouse (100) has a thickness of 1 to 1.5 cm and is a thin plate shape, so it can be stored together in a laptop bag or pad storage bag, and even when stored, it does not protrude convexly, so it does not spoil the aesthetics.

Meanwhile, when using a plate-type folding mouse (100) for use with a notebook or pad, the user holds the mouse body (110) and the grip folding part (120) with both hands respectively and presses the grip folding part (120) downward to rotate the grip folding part (120). When the grip folding part (120) rotates, the angle limiting protrusion (112b) moves along the angle adjustment slit (125b), and when the angle limiting protrusion (112b) comes into contact with the bottom of the angle adjustment slit (125b), it no longer rotates.

As shown in Fig. 2 and Fig. 6 (b), the user positions the front ground contact slope (111b) and the rear ground contact slope (121a) of the folded plate-shaped folding mouse (100) so that they are in contact with the ground or the mouse pad (G), respectively. At this time, the mouse body (110) and the grip folding part (120) form symmetrical slopes on both sides with the folding part joining axis (112) and the central rotation axis (125) of the central area as the center.

As shown in Fig. 3, the user places the palm on the area of the centrally protruding folding joint shaft (112) and the central rotation axis (125), the thumb contacts and supports the side wall of the grip folding part (120), and the index finger contacts the scroll wheel (130) to use the mouse. With the mouse body (110) and the grip folding part (120) folded in this manner, the user presses or pulls the scroll wheel (130) forward and backward to move the screen, and uses it by clicking the left button (113a) or the right button (113b).

When the notebook or pad is finished being used, the folding part (120) and the mouse body (110) are rotated in opposite directions again to unfold the plate-shaped folding mouse (100) into a plate shape as shown in Fig. 1. The unfolded plate-shaped folding mouse (100) is stored together with the notebook or pad.

As seen above, the plate-shaped folding mouse according to the present invention has the advantage of being provided in a thin plate shape, so that it does not take up space and does not protrude externally even when stored together with a laptop or pad, allowing for neat storage.

In addition, when using it, the mouse body and the grip part can be folded at a certain angle and transformed into a form that the user can easily grip with their hands.

At this time, the scroll wheel is also equipped with an infinite track wheel shape with a thickness corresponding to a thin plate-type folding mouse, so that both the function and aesthetics of the scroll wheel can be satisfied.

In addition, the folding angle of the plate-shaped folding mouse can be limited by the angle limiting protrusion so that the angles in the unfolded and folded states can be stably maintained.

The embodiments of the plate-shaped folding mouse of the present invention described above are merely exemplary, and those skilled in the art to which the present invention pertains will readily appreciate that various modifications and equivalent other embodiments are possible. Therefore, it will be readily understood that the present invention is not limited to the forms mentioned in the detailed description above. Accordingly, the true technical protection scope of the present invention should be determined by the technical idea of the appended claims. In addition, the present invention should be understood to include all modifications, equivalents, and substitutes within the spirit of the present invention defined by the appended claims and the scope thereof.
