A mouse device with inclined side grip

Abstract

An obliquely holding type mouse device comprises a tail portion and a head portion of a pointing part, wherein the head portion is controlled by fingers, and the tail portion allowing hand holding supports the head portion. The head portion comprises a front surface, an operation bottom surface and a rear surface, the front surface contacts with an index finger and a middle finger, the inner surface contacts with a thumb, the operation bottom surface contacts with the horizontal plane, and the rear surface is connected with the tail portion. The tail portion comprises a holding portion and a base, the holding portion contacts with a ring finger and a little finger, the base supports the device, and one end, away from the base, of the holding portion is connected with the head portion. The obliquely holding type mouse device can be obliquely held with a hand to enable each finger of the hand to be in a naturally bent state, unnatural distortion of an arm and a wrist can be avoided to protect hand sensitive areas from compression, and accordingly holding comfort is improved.

Description

technical field [0001] The invention belongs to the field of computers and relates to a pointing device, in particular to a computer mouse pointing device Background technique [0002] Computer mouse pointing devices are usually used to control the movement of the cursor on the computer screen. When using this type of pointing device, the forearm, wrist and hand often have to maintain a fixed posture for a long time. If this posture is not for the forearm, wrist The posture in which the head and hands are naturally placed on the table will inevitably make the muscles continue to be tense, which will cause fatigue and discomfort after a long time. This requires that the pointing device has an appropriate structure to provide a suitable position and angle for the hand to hold, preventing fatigue and discomfort, and changes to the traditional structure will not cause other problems in use. [0003] The patent part of the existing pointing device has considered the requirements...

AI Technical Summary

Problems solved by technology

This design fully considers the posture of the hand when holding the mouse, the support surface fits naturally with the hand, and the design of the key angle can avoid accidental rotation and offset of the mouse, but this design has defects. First, the design The left button is located on the upper part, and the part extending outward from the top provides little finger placement. Different people have different hand widths, so this design cannot guarantee that the index finger of hands of different widths can be placed above the normal direction of the left button while the little finger can be placed on the left button. On the lower extension part, under the premise of ensuring the proper position of the index finger, if the hand is wider, there will be nowhere to put the lower finger. If the hand is narrower, there will be no support surface on the outside of the hand for upward support. Keeping the arm or wrist lifted up will cause tension and discomfort in the arm or wrist after a long time; second, because the curvature radius of the lower part of the design is the largest, it gradually decreases from bottom to top, while the length of the middle finger is the longest, and the ring finger is the longest. Shorter, the little finger is the shortest, so when the mouse is held by the hand, the lower ring finger and little finger cannot fully surround the lower edge of the mouse. Aggravate the fatigue of the forearm; third, because the support surface where the four fingers are located is always inclined outwards and downwards from top to bottom, when the hand is placed on the mouse, it will inevitably cause the ring finger and little finger located below to be placed relatively outward, and the little finger outside This is different from the state where the little fingertip is the closest to the palm when the hand is naturally placed on the bottom surface of the work and the four fingers are naturally bent. Keeping this hand shape for a long time will cause fatigue on the outer muscles of the hand.

[0008] Xiao Xiangmao's patent 201320488207.9 discloses a mouse. The mouse shell is a vertical structure, which is characterized in that it guides the palm side to hold the mouse to operate. The keys controlled by the index finger are located above the keys controlled by the middle finger. The design fully considers the natural curvature of the four fingers when the hand is placed on the bottom surface of the work. The direction of the buttons is backward to prevent accidental rotation and offset of the mouse. It is at a vertical angle. When holding the mouse sideways, the forearm needs to be twisted from the natural position to a certain angle. Similar to the traditional mouse, it will inevitably make the muscles tense continuously, and will cause fatigue and discomfort after a long time

In addition, the design places the pulley at the most inflexible thumb position control, and the sliding direction is perpendicular to the bending direction of the thumb joint, which is very inconvenient to operate
