Description

  The present invention relates to a mouse used in a personal computer, and more particularly to a mouse held by a protrusion.

  Recently, the number of people who use personal computers increases day by day, and for those who use a so-called mouse for a long time, the fit of the mouse is important for reducing fatigue or obtaining a natural feeling of operation. However, the size of the hand, the length of the fingers, and the flesh are each person, and it is difficult to deal with everything in detail.

  For example, Japanese Patent Laid-Open No. 2002-287898 proposes a thin mouse operation aid so that the proper position of the thumb and ring finger can be determined, and in a sense, improves the fit, but improves the structure of the mouse. It is not something that is going to be solved. Japanese Patent Application Laid-Open No. 2009-3914 can be said to improve the fit by considering the structure of the mouse, such as allowing the grip portion to be tilted, but it cannot be said to correspond finely. Furthermore, although the thing of Unexamined-Japanese-Patent No. 2009-15831 cannot be called a mouse | mouth, it considers the whole form and arrangement | positioning of a signal input part, and has proposed the user friendly input device.

  By the way, the mouse is mainly operated with the index finger and the middle finger, and the mouse is held with the thumb, the ring finger, the little finger, and the palm. In general, it is considered that the larger the contact area of the hand with the mouse, the easier it is to hold the current mouse as one smooth mass. However, there are cases where it is better not to touch the palm from an ergonomic point of view or depending on the usage scene. In addition, due to recent technological advances, the internal mechanism has been rapidly miniaturized, and most of its previously required volume is no longer necessary. In the case of a general industrial product, if the internal mechanism becomes small, the volume of the product becomes small or thin. However, the mouse was designed based on the size of the hand from an ergonomic point of view, and a product that is simply reduced in size and thickness cannot obtain a sufficient fit, is easily fatigued, and is not easy to use. It becomes a thing.

  As described above, small and thin mice have been distributed in the market due to the evolution of technology, but with the current state of being simply small and thin, users cannot get a good fit, Because it puts a burden on the hand, it is not suitable for long-time use.

  The present invention seeks to solve the disadvantages of inconvenience associated with downsizing and thinning of a mouse from the viewpoint of ergonomics, and provides a small and thin mouse with a fit that can withstand long-term use. For the purpose.

In order to achieve the above object, the present invention forms a mouse with a main body including a key operated by the index finger and the middle finger, and protrusions that can be adjusted in several positions and postures provided on the main body. The adjustable position and orientation of the protrusions allow for a variety of hand sizes and user preferences, and this mouse fits the palm, thumb, ring finger, and little finger for a long time. There is little that a user feels stress even when using it.
Note that “position adjustment” is based on displacement in the plane (xy coordinate plane), and “posture adjustment” is in a space in which vertical displacement is added (xy coordinates). This is due to the displacement at. For convenience of explanation, terms such as left and right, front and rear, and top and bottom are used, but they are relative and vary depending on the use state of the mouse.

  A unique structure that holds the mouse with a protrusion that can be adjusted in position and orientation, making the main body with the substrate smaller and thinner, making it smaller and lighter than conventional mouse products with a solid fit. It becomes possible to make it.

  The fine adjustment function that can be obtained by moving or displacing the protrusions is the difference in hand size, finger length, and flesh that each user has, which was impossible with conventional mouse products. It can meet the detailed requirements due to differences. In addition, since the desk height is constant, it is possible to cope with individual differences in the approach angle to the mouse that changes depending on the height and the posture used.

  A mouse is provided with a main body, an arm, a right plate, a left plate, and a center plate. The main body includes two keys for input and an internal mechanism for transmitting key operations to the computer. One end of the arm part is attached to the main body part so as to be able to be rotated and positioned, and the center plate and the left plate are attached to the other end so that the position and posture can be adjusted. The right plate is attached coaxially with one end of the arm part so as to be rotatable to the main body part and to be adjustable in the left-right direction. The central plate is attached to the other end of the arm portion so that its posture can be adjusted by movement combining vertical swing and horizontal rotation by a shaft different from the left plate. The right plate is provided with a ring finger / little finger hook as a protrusion, the left plate is provided with a thumb hook as a protrusion, and the center plate is formed as a protrusion with a curved surface as a palm rest. The arm portion may be configured integrally with the main body portion.

Hereinafter, the first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows a mouse 1 according to the present invention, which includes a main body 2, an arm 3, a right plate 4, a left plate 5, and a central plate 6. All are molded parts such as ABS resin except for the shaft.
The main body 2 (FIG. 2) includes two input keys 8 and an internal mechanism 9 for transmitting the operation of the keys to the computer at the front part on the substrate 7. The internal mechanism 9 has the same structure as the conventional one, but is photoelectric and small, and is disposed between the substrate 7 and the input key 8. The main body 2 has a thin and small configuration including the input key 8. In addition, although the mouse | mouth of an Example shows the thing of a wireless system, it can utilize also as a code system. The code drawing position in the case of the code method is shown by a chain line in FIG. The rear end of the substrate 7 is a bearing portion 10.

The arm portion 3 (FIG. 2) has a front end as a receiving screw portion 11 and a rear end as a circular and horizontal support portion 12.
The right plate 4 is formed as a ring finger / little finger hook 13 by folding the right side (bottom side) of a plate body based on a triangle upward to form a protrusion. An annular bearing portion 14 is formed so as to protrude from the apex portion facing the bottom side of the triangular plate body. The arm portion 3 and the right plate 4 are inserted into the bearing portion 10 of the main body portion 2 from below, with the receiving screw portion 11 of the arm portion 3 overlapped with the upper surface of the bearing portion 10 and the bearing portion 14 of the right plate 4 overlapped with the lower surface. It is attached coaxially by the male screw pin 15 (FIG. 2, first stage assembly). By screwing the upper end of the screw pin 15 into the receiving screw portion 11 of the arm portion 3, the arm portion 3 and the right plate 4 are fixed to the main body portion 2, but when the screw pin 15 is loosened, the arm portion 3 with respect to the main body portion 2 is fixed. And the right plate 4 can be rotated in a horizontal plane to adjust the position.

  In this embodiment, the left plate 5 (FIG. 3) has a shape in which the left half of a flat spatula-like plate body is folded upward with a fold line that is skewed with respect to the longitudinal direction. A thumb hook 17 is provided as a folded protrusion. The horizontal portion 16 is formed by an annular wall from which a bearing portion 18 having a long hole extending in the left-right direction protrudes, and the thumb hook portion 17 is arranged so as to protrude forward and upward from the horizontal portion 16.

The left plate 5 is attached to the circular support portion 12 of the arm portion 3 using an arm lower component 19 (FIG. 3) and an arm upper component 20.
The arm lower component 19 is formed by integrally forming a washer portion 21 and a support reinforcing portion 22, and the washer portion 21 includes a bearing portion 24 in the center. The bearing portion 24 has an annular shape that penetrates the through hole 23 provided in the support portion 12 and protrudes upward.
The arm upper component 20 is formed by integrally forming a washer portion 25 and a spherical bearing portion 26, and has a structure in which each portion overlaps a corresponding portion of the arm lower component 19.

  The washer portion 25 has a through hole 28 into which a bolt pin 27 (FIG. 3) is inserted at the center, and a through hole 30 into which a screw pin 29 (FIG. 4) is inserted at the center of the spherical bearing portion 26. Has been. The upper surface of the spherical bearing portion 26 is a spherical surface that is recessed downward and inclined rearward. A screw hole 31 into which the tip of the screw pin 29 is screwed is formed corresponding to the through hole 30 in the center of the support reinforcing portion 22 of the arm lower part 19 that corresponds to the spherical support portion 26.

The left plate 5 is attached to the support portion 12 of the arm portion 3 as follows.
First, the support part 12 is sandwiched between the washer part 21 of the arm lower part 19 and the washer part 25 of the arm upper part 20, and the arm lower part 19, the arm upper part 20 and the support part 12 are properly overlapped. Next, the bearing portion 18 of the left plate 5 is applied to the lower surface of the washer portion 21 of the arm lower component 19, and in this state, the bolt pin 27 is inserted into the through hole 28 of the arm upper component 20 from above, and the horizontal portion 16 of the left plate 5. Penetrate to the bottom. And the nut 32 is screwed into the front-end | tip of the penetrated bolt pin 27 (FIG. 3, the 2nd step assembly | attachment).

  By screwing the nut 32, the three parts, that is, the arm upper part 20, the arm lower part 19 and the left plate 5 are fixed to the arm part 3. When the nut 32 is loosened, each part is centered on the bolt pin 27. It can be rotated on a horizontal plane. The arm upper part 20 and the lower part 19 are rotated with respect to the support part 12 of the arm part 3 in an integrated state.

  The central plate 6 (FIG. 4) is a spherical surface that is smooth in the front-rear and right-and-left directions so that the upper surface of the plate has a liver shape as a whole. The curvature of the spherical surface corresponds to the curved surface of the inner surface of the palm that is seen when the right palm is turned up and lightly rolled up to receive water, and is a kind of protrusion. Since the mouse of this embodiment is used with the right hand, the outline of the liver shape has a shape in which the right side protrudes and the left side is recessed in plan view. The curve on the left corresponds to the so-called fate line on the inside of the palm.

A spherical portion 33 that sinks downward is formed in the approximate center of the central plate 6, and the central portion is a through-hole 34 having a large diameter.
The central plate 6 uses a washer 35 and an annular spacer 36 on the spherical bearing portion 26 of the arm upper part 20 attached to the arm portion 3, and the spacer 36 is placed on the spherical bearing portion 26. 6 is overlapped at the location of the spherical surface portion 33, a washer 35 is further overlapped, a screw pin 29 is inserted from above, and the tip thereof is screwed into the screw hole 31 provided in the support reinforcing portion 22 of the arm lower component 19. Install (FIG. 4, third stage assembly).

When the screw pin 29 is tightened, each component is fixedly attached. However, when the screw pin 29 is loosened, the central plate 6 moves along the spherical surface of the spherical surface portion 33 and moves in a combined manner (spherical surface). Slide), and the position and orientation can be adjusted.
The spacer 36 is a spherical surface having a concave upper surface and a spherical surface having a convex lower surface, and corresponds to the spherical surfaces of the spherical surface portion 33 and the spherical bearing portion 26, respectively. The spacer 36 may not be used.

FIG. 5 is a plan view of this embodiment having the above-described configuration and the assembly is completed, and FIG. 6 is a bottom view thereof. This arrangement is the standard arrangement.
When the main body 2 is taken as the center, directions in which the positions of the arm 3, the right plate 4, the left plate 5, and the center plate 6 can be adjusted are as indicated by the respective arrows. As described above, the center plate 6 can be swung up and down as described above, and the posture can be adjusted (FIGS. 8 and 9 described later).

  The arm portion 3 can be horizontally adjusted as indicated by an arrow A around the screw pin 15 to be adjusted in position. Accordingly, the position of the entire group of the left plate 5 and the central plate 6 attached to the rear end of the arm portion 3 by the bolt pin 27 and the screw pin 29 can be adjusted with respect to the main body portion 2. This adjustment affects the rotation angle of the wrist when operating the mouse 1 (approach angle in plan view), and affects the feeling of fit at the wrist location.

The position of the right plate 4 can also be adjusted by rotating horizontally as indicated by the arrow B around the screw pin 15. This adjustment changes the tilt angle of the ring finger / little finger hooking portion 13 and affects the fit of the ring finger / little finger to the mouse 1 when the mouse is used.
The left plate 5 can be horizontally rotated around the bolt pin 27 as indicated by an arrow C, and can also be moved in the horizontal direction in the D direction by the long hole of the bearing portion 18. Thereby, the inclination angle of the thumb hook 17 and the interval of the thumb hook 17 with respect to the ring finger / little finger hook 13 are adjusted, and a feeling of fit when the mouse 1 is gripped by hand (usually by thumb, ring finger, little finger) is adjusted. It depends on you.

  The center plate 6 can be horizontally rotated around the screw pin 29 as indicated by the arrow E, and as shown by the arrow F in FIGS. 8 and 9, the spherical portion 33 and the spacer 36 of the center plate 6 or the upper part of the arm. The spherical support structure with the 20 spherical support portions 26 enables swinging by a spherical slide back and forth and left and right. For this reason, the center plate 6 can adjust the posture of the palm portion (projection portion with a curved surface) which is the upper surface thereof. This posture adjustment affects the operation of the mouse 1, particularly the feeling of fit between the mouse and the hand (approach angle in side view) that is felt when the mouse 1 is pushed and moved by the inner surface of the hand.

  FIGS. 7A to 7F show this adjustment in a plan view. (A) shows the standard position, (b) shows the position where the left plate 5 has moved in the direction of arrow D, (c) shows the position where the left plate 5 has moved in the direction of arrow C, and right plate 4 has moved in the direction of B. Indicates the position. Further, (d) to (f) show displacements related to the arm portion 3, (d) shows a standard position, (e) shows a position where the arm portion 3 has moved in the direction of arrow A, and (f) Indicates the position where the upper arm part 20 (along with the lower arm part 19) has moved in the C direction from the standard position.

Because of the above structure and function, the mouse 1 first adjusts the position of the arm unit 3, the right plate 4, the left plate 5, and the posture of the center plate 6 according to the user's preference. Adjustment is performed with the screw pin 15, bolt pin 27, and screw pin 29 loosened. As a method, all the pins are loosened, the right hand is placed on the mouse 1, and the position and posture of each part are determined in such a manner that each part is familiar with the hand while simulating the mouse operation. Then, the position and posture determined by tightening the screw pin or the bolt pin may be fixed, or the position or posture may be determined and fixed sequentially for each part.
In this way, it is possible to pursue a fine fit.

  8 and 9 show an example in which the posture of the central plate 6 is adjusted according to the size of the right hand that operates the mouse 1, and the relatively small hand of FIG. 9 is compared to the large hand of FIG. In this case, it can be seen that the swing angle of the central plate 6 is lower and the inclination is stronger. In the case of a large hand, the height of the entire central plate 6 is adjusted by using a spacer 36 between the central plate 6 and the upper arm part 20.

  Conventional products that pursue a high fit feel to hold the main body, so the area where the thumb, ring finger, and little finger fit is required on both sides of the operation key part. Was impossible. However, as in this embodiment, in the present invention, since the operation key portion can be created considering only the thickness of the contents, it can be created with a small thickness as shown in the figure. On the other hand, when the mouse is operated, the hand has a natural arch shape, which is ideal for reducing the fatigue of the mouse operation.

FIG. 10 shows another embodiment. The difference from the first embodiment is that the movable arm portion 3 is not provided, and the left plate 5, the arm lower component 19, and the arm upper component 20 are formed on the substrate 7 of the main body 2. It is attached directly to the rear end. For this reason, the position of the left plate 5 and the center plate 6 cannot be adjusted with respect to the main body 2 by horizontal rotation with the left plate 5 and the central plate 6 as a group.
However, other configurations are the same as those in the first embodiment, and the position and posture of each part of the mouse can be adjusted until the mouse 1 can be operated with a sufficient fit even within a limited range. . In addition, since there are fewer parts, there is an advantage that it can be produced at low cost.

The above description is a preferred embodiment of the present invention and does not limit the scope of the present invention. Therefore, all equivalent changes or corrections completed within the scope not departing from the spirit disclosed in the present invention shall be included in the scope of patent application in this proposal.
That is, although the configuration of using the right hand is shown, the configuration can be similarly applied to the left hand.
The central plate 6 has a structure that is supported by the support portion of the main body 2 or the arm portion 3 so that the posture can be adjusted. However, the support structure is not limited to a spherical slide, but is a rotation of inclined surfaces. May be.
The spacers 36 shown in the embodiments may not be used, and conversely, a plurality of spacers may be used or those having different thicknesses may be prepared.

  The main body 2, the arm 3, the ring finger / little finger hanging part 13, the thumb hanging part 17, and the central plate 6 forming the palm rest part are fit for the design including the respective dimensions and the design including the overall dimensions. Is free as long as it is not damaged. It is also conceivable to prepare various dimensions (including adjustment widths) and designs and to use them in combination or interchangeably.

The central plate 6 that forms the arm portion 3, the ring finger / little finger hanging portion 13, the thumb hanging portion 17, and the palm rest portion is formed of a material that allows the user to freely shape the shape by applying heat to obtain a further fit. It is also possible.
The right plate 4 may be provided with the same configuration as that of the bearing portion 18 having the long hole of the left plate 5 so that the right plate 4 can also be moved horizontally and horizontally.

  It can be used as an easy input device for computers. In addition, the wide adjustment range by the unique configuration is effective for people with some handicap.
