Mousepad device for preventing musculoskeletal system {A Mouse-pad Device Of Slope Control Possible Structure}

The present invention relates to a pair of mouse pad structure consisting of a hinge coupling structure in which one mouse pad is rotatable with respect to the other, and more particularly, provides a toothed shaft joint shape on one side of the hinge coupling structure and the tooth shaft joint The present invention relates to an ergonomic mouse pad device having a structure in which coil springs are embedded on the other side to force the coupling state, and spaced for compressing the coil springs and thus releasing the coupling state.

In general, as the concept of a graphical user interface (GUI) is introduced into a computer, a keyboard has a limitation as an input device, and thus a mouse is widely used as a separate input device.

The mouse has a structure in which a spherical rubber ball is rolled in the axial direction on the same plane to change the position of the cursor in the monitor, designating an icon or a menu bar to be selected, and having two or three buttons to select it. The structure which becomes is also used.

In the case of using such a mouse, it is common to place a square mouse pad on a horizontal desk at the bottom thereof and roll the ball on the horizontal desk. This is because when the ball is used in a curved or uneven surface during rolling, the position of the cursor cannot be used, and as the foreign material flows along the surface of the ball, the ball is slowed down and interposed therein.

The same applies to a mouse employing the optical sensor. The conventional mouse pad is usually made of a plastic sheet in the form of a thin sheet or using rubber having a predetermined thickness and elasticity. It is a structure in which the plane forms a plane parallel to the ground.

However, when working with a computer for a long time, and in the case of a clerical worker who needs to perform this work repeatedly every day, even if a small mouse is used, the deformed posture deforms the musculoskeletal system such as the shoulder ligament. The crowd is due to follow.

In addition, the conventional mouse pad has a structure having a horizontal surface, so that the palm is always facing the bottom surface when using the mouse. By the way, the body of the human body (particularly the upper body) is upright in the vertical direction during work, and the vertically upright shoulder and the palm facing the horizontal plane are connected by the angle of the shoulder joint, heel joint, wrist joint. At this time, as the working time becomes longer and the movements of muscles and joints become finer, pain in the related musculoskeletal system begins to occur.

Nevertheless, the conventional mouse pad has a horizontal structure that allows the palm to face the floor as mentioned above, so that the palm is pressed for a long time to give a strain to the wrist, shoulder and ligament, which is a human skeleton The problem arises from the problem of the horizontal plane structure of the conventional mouse pad which does not consider the structure of the.

In addition, the ligaments are unlikely to be trained when constant stress is applied, unlike muscles, which are likely to cause musculoskeletal disorders. Therefore, in view of the increasing work pattern using a mouse, the conventional mouse pad structure as described above Use should be improved. Accordingly, there is an urgent need to develop an ergonomic mouse pad that can maintain the shape of the human body without placing stress on the ligaments of the shoulders at a predetermined inclination angle so that the palms do not have a posture facing directly to the floor (or the ground). I do.

Therefore, the present invention was devised in view of the above-described conventional problems, and the first object of the present invention is to have a structure in which two mouse pads are hinged so as to be folded, so that one mouse pad is connected to the other. It is to provide a mouse pad device for preventing the musculoskeletal system of the structure fixed inclined relative to.

The second object of the present invention is to provide a musculoskeletal prevention mouse pad device having a structure in which a toothed shaft joint structure is formed at one side of the hinge coupling portion so that the inclination angle can be easily adjusted step by step according to the user's circumstances.

In addition, the third object of the present invention, by having two mouse pads having a structure in which one is folded relative to the other, it is possible to use a mouse pad in parallel with the ground in addition to the use of the inclined mouse pad It is to provide a mouse pad device for preventing the musculoskeletal system structure.

The second hinge portion comprises a first hinge tube and a second hinge tube which are formed on the same axis and spaced apart from each other on the side of the second pad so as to allow the respective fitting rods to be rotatably fitted.

The first tooth shape and the second tooth shape protrude along the axial direction, respectively, on one end edge of the hinge rod and the other end edge of the first hinge tube facing each other so as to allow the stepwise folding of the second pad to the first pad. It is achieved by a musculoskeletal prevention mouse pad device characterized in that it has a toothed axial joint structure.

Here, the coil spring for pressing the first fitting rod toward the first hinge tube is inserted along the axial direction on the outer periphery of the second fitting rod so that the first tooth is tooth-coupled based on the elastic force with respect to the second tooth.

Next, with reference to the accompanying drawings with respect to the mouse pad device for preventing musculoskeletal system inclination adjustment according to the present invention will be described in detail.

1 is a perspective view of a mouse pad device according to the present invention. As shown in FIG. 1, the mouse pad device 1000 according to the present invention has a hinged structure in which two pads are relatively rotatable. In this case, the toothed shaft joint structure is formed on one side of the hinge connection structure, so that the second pad 300 forms a predetermined slope according to rotation while selectively releasing the tooth coupling with respect to the first pad 100.

To this end, the mouse pad device 1000 has a structure in which adjacent sides are hinged, and the first pad 100 and the second pad 300 made of a plastic resin material and a hinge connection structure of the pads 100 and 300. It comprises a first hinge portion 200 and the second hinge portion 400 formed integrally with each side portion.

Here, the first pad 100 has a rectangular shape, and a first sheet 110 of a fabric material is attached to an upper surface thereof, and a first hinge portion 200 is provided along a side of a hinge connection portion.

The first hinge portion 200 is a hinge rod 210 integrally formed at the center of the side portion, and the first fitting rod 210a and the second fitting rod 210b protruding to both sides of the hinge rod 210. Is done. The fitting rods 210a and 210b are relatively smaller in diameter than the hinge rods 210, and at one end of the hinge rods 210 around the protruding origin of the first fitting rods 210a. Protruding in the axial direction to the first tooth 210c.

The first tooth (210c) is a plurality of protruding in a triangular shape along the rim toward one side axial direction, the tooth coupling by engaging corresponding to the second tooth (430) provided in the second hinge portion (400) To achieve this (see FIG. 2).

In addition, the second pad 300 having the second hinge portion 400 has the same size and shape as the first pad 100 and has a relatively small area on the top surface of the second sheet 310. It is bonded together.

In this case, two hinge pipes 410 and 420 forming the second hinge portion 400 are integrally formed at the adjacent edges so as to be connected to the first pad 100 among the relatively long edges of the second pad 300. It is formed. The first fitting rod 210a is fitted into the first hinge tube 410 located on one side of the hinge tubes 410 and 420, and the second hinge tube 420 is attached to the second hinge tube 420 on the other side. Is fitted. Accordingly, the second pad 300 may be folded along the hinge connection structure with respect to the first pad 100.

The range of rotation angles of the second pad 300 that is possible according to the folding is about 180 ° from the top surface of the second pad 300 being in close contact with the top surface of the first pad 100 to be fully extended to form the same plane. It is possible to the extent. Therefore, the second pad 300 may form an inclined surface with respect to the first pad 100 within the rotation angle range.

In addition, the first hinge tube 410 is engaged with the first tooth (210c) formed on one end of the hinge rod 210, as described above, the first fitting rod (210a) is fitted into the toothed coupling. To this end, the second tooth 430 of the corresponding shape is formed to protrude. Therefore, a toothed shaft joint structure in which the respective teeth 210c and 430 are engaged as the first fitting rod 210a enters and is inserted into the inlet is possible.

In this case, the total length of each of the fitting rods 210a and 210b is relatively smaller than the total depth of each of the hinge tubes 410 and 420. Accordingly, the tooth coupling state of each of the teeth 210c and 430 is connected to the fitting rod. It can be released by pulling to the other side. However, in addition to the release, the tooth coupling state needs to be constantly maintained for this purpose. To this end, a coil spring 500 is embedded in the second hinge pipe 420, so that the second hinge pipe 420 is formed. The coil spring 500 is fitted to the outer circumference while the two fitting rods 210b are inserted.

Therefore, each of the teeth 210c and 430 is coupled to the teeth while the entire hinge rod 210 and the fitting rods 210a and 210b are pressed against the one hinge tube 410 by the elastic force of the coil spring 500. This can be announced. In order to release, it is possible to reduce the spacing caused by the difference in length (or depth) between the fitting rods 210a and 210b and the hinge tubes 410 and 420. That is, when holding the first pad 100 and pulling the rods and each fitting rod (210a, 210b) toward the second hinge tube 420, the spacing is reduced, each tooth (210c, 430) is relatively apart from each other, the tooth coupling In this release and release state can be rotated by holding the second pad 300 free to rotate it is possible to adjust the inclination angle of the inclined surface.

By the way, as shown in Figure 3, the lower portion of the first pad 100, the support 120 is formed by repeatedly bending the wire (or plastic material) to the lower edge of the first pad 100. The support 120 has both sides facing the same direction and is bent vertically between the two sides to form a long support structure, and the frictional packing 120a of rubber material is fixed to this part. Each side portion is fitted along the lower rim of the first pad 100 so that the friction packing 120a can be pushed or pulled to hold the fitted portion, and some of the fitted portions are visually checked for the degree of fitting. The lower portion of the first pad 100 is dug and exposed.

At this time, the support 120 is fitted so as to be movable toward the hinged second pad 300, which is, if the second pad 300 is inclined within about 90 ° ~ 180 ° When the first pad 100 is separated from the ground by the weight of the second pad 300, that is, when the posture becomes unstable, the second pad 300 is pulled toward the second pad 300 to further extend the support structure for the second pad 300. To operate.

Figure 2 is an exploded perspective view of the mouse pad device shown in Figure 1, Figure 3 is a perspective view showing a support according to the present invention. As shown in FIGS. 2 and 3, the second hinge portion 400 of the second pad 300 is hinged to the first hinge portion 200 of the first pad 100, thereby horizontally laying on the ground. Rotation of the second pad 300 is possible within about 180 ° with respect to the first pad.

Particularly, the first tooth shape 210c formed at one end of the hinge rod 210 in the first hinge part 200 is the second tooth shape formed at the inlet edge of the first hinge pipe 410 in the second hinge part 400. With the implementation of the toothed shaft coupling structure engaged with 430, the second pad 300 can be maintained at its current rotational tilt angle.

At this time, if adjusting the inclination angle of the second pad 300, holding the first pad 100 in the fixed state of the second pad 300, and pulls to the other side, each fitting rod for each hinge pipe (410, 420) The tooth coupling structure of each tooth 210c and 430 that is engaged with the first pad 100 is pushed back by the length difference of 210a and 210b is released.

And while holding and rotating the second pad 300, the inclination angle can be adjusted, and when the first pad 100 is released after rotation, when the second pad pulls the first pad 100 in the second hinge tube 420 As the coil spring 500, which was compressed by the fitting tube, expands, the hinge rod 210 and the fitting rods 210a and 210b are pushed to one side to engage the teeth 210c and 430 again. Therefore, the rotation tilt angle of the second pad 300 may be maintained in an adjusted state.

At this time, in order to prevent the entire mouse pad device 1000 from tilting in accordance with the rotational inclination angle, the support 120 is pulled out from the first pad 100 by an appropriate length. As a result, the unstable support posture according to the inclination can be corrected, and the pad device 1000 can be fixed without wobble or the like.

4 is a first use state diagram of the mouse pad device according to the present invention, Figure 5 is a second use state diagram of the mouse pad device according to the present invention. As shown in FIGS. 4 and 5, the second pad 300 is rotated at a rotational inclination angle suitable for its body shape, and the teeth 2000c and 430 are engaged with each other, and then the mouse 2000 is moved to the second pad 300. It can be placed on the top of the board and work on the computer.

At this time, the support 120 may be pulled out from the first pad 100 in a proper length in accordance with the rotational inclination angle to stabilize the overall position of the mouse pad apparatus 1000.

The inclination angle can be arbitrarily adjusted according to the body shape, in this case by pulling the first pad 100 to the other side as mentioned above by integrally forming the hinge tube and each fitting rod (210a, 210b) to push back The tooth coupling state of each tooth 210c or 430 is released.

Then, when the second pad 300 is rotated by a desired angle and the first pad 100 is released, the teeth 210c and 430 are engaged again by the elastic force of the coil spring 500, which is compressed, and the tooth coupling is made. The inclination angle of both pads can be maintained.

In addition, the support 120 of the lower portion of the first pad 100 may be pulled out to realize a stable support structure such that the first pad 100 forms a horizontal plane with the ground at the inclination angle.

In addition, the pads 100 and 300 maintain a predetermined inclination angle, and the mouse 2000 may be used on the second pad 300 as well as the first pad 100 in a horizontal state as shown in FIG. 5. You can also use the mouse (2000) over the ().

In the mouse pad device 1000 capable of tilt adjustment according to the present invention as described above, the pads 100 and 300 are hinged in a relatively short length, in addition to the structure in which the relatively long side is hinged. The use of structures is also possible.

In addition, each tooth (210c, 430) is made of a triangular, in addition to the shape of each tooth (210c, 430) that teeth generally have, such as square, trapezoid can be selected. Since the rotation unit of the rotation angle is determined according to the number or pitch of the teeth, the design can be appropriately selected within the level range of those skilled in the art. In addition, in addition to the coil spring 500 as a pressing means for tooth coupling of the teeth (210c, 430), it can be replaced by any type of spring.

And the support 120 may be used in addition to the form of repeated bending of the wire, in the form of a plate inserted into the structure that can be sliding in the lower portion of the first pad 100, in addition, a plurality of hook-type connection structure of the first It is also possible to use a structure provided along the side of the pad 100 to support it as needed.
