Elastic power-assisted fingerstall for assisting typewriting

Abstract

The invention discloses an elastic power-assisted fingerstall for assisting typewriting. The elastic power-assisted fingerstall comprises a near knuckle sleeve arranged on a near knuckle of an index finger in a sleeving mode and a wrist sleeve arranged on a wrist in a sleeving mode. The near knuckle sleeve is connected with the wrist sleeve through an elastic strip, and the elastic strip is distributed along the back of the index finger and the back of the palm; the elastic strip is provided with a tension degree adjusting mechanism so that the elastic strip can be in an elastic stretching state in the pre-typewriting state. After a user wears the elastic power-assisted fingerstall, the tension degree of the elastic strip is adjusted through the tension degree adjusting mechanism, so that the elastic strip is in an elastic stretching state in a pre-typewriting state. When the keyboard or the mouse is knocked and the index finger is lifted, the elastic strip elastically contracts along the finger back to provide backward and upward pulling assisting force; the working mode that the index finger completely depends on active contraction is changed into the working mode that active contraction and passive contraction are mixed, the index finger extensor contraction strength is reduced through assistance, the tension degree of the index finger extensor and auxiliary muscle groups of the index finger extensor is effectively relieved, and therefore the morbidity probability of chronic strain is reduced.

Description

Technical Field

[0001] The present invention relates to an auxiliary finger sleeve that provides elastic assistance during typing. Background Art

[0002] The index finger is divided into three sections in total. The first section near the palm is called the proximal phalanx; the second section between the first and third sections is called the middle phalanx; the third section away from the palm is called the distal phalanx. When typing, the workload of the index finger is the heaviest. Typing on the keyboard can be divided into two actions: lifting the finger and dropping the finger. Among them, the action of lifting the finger belongs to the dorsal flexion of the finger joint, and the action of dropping the finger belongs to the palmar flexion of the finger joint. From a physiological point of view, the palmar flexion of the finger joint is usually easier to perform for the following reasons:

[0003] Natural posture: Fingers are usually slightly flexed in a relaxed state, and this posture is more in line with the natural shape of the fingers. The palmar flexion action is closer to the natural resting state of the fingers, so it is easier to complete. Dorsal flexion requires the finger to extend from the natural bent state in the opposite direction, which requires more muscle strength and joint flexibility.

[0004] Muscle strength: The flexor digitorum (responsible for palmar flexion) is usually stronger than the extensor digitorum (responsible for dorsal flexion). This is because the flexion actions of the fingers (such as grasping and pinching) are more frequent in daily life, and the flexor digitorum has been exercised more. The extensor digitorum is relatively less used, so it may be slightly weaker in strength and endurance.

[0005] Joint structure: The joint structure of the fingers is more adapted to flexion movement. The shape of the joint surface and the ligament structure of the metacarpophalangeal joint and the interphalangeal joint make the palmar flexion action smoother. Dorsal flexion needs to overcome more joint resistance, especially when the fingers are already in a slightly flexed state during typing.

[0006] When lifting the index finger, it mainly relies on the contraction of the extensor digitorum on the dorsal side of the index finger; although the extensor digitorum is also connected to the index finger, it mainly controls the straightening or extension of the middle finger, ring finger, and little finger, and plays a certain role in assisting the straightening of the index finger during the typing action. The lumbrical muscle on the palmar side of the index finger participates in the precise control and coordination of the index finger action during typing on the keyboard. In addition, when continuously typing for a long time, in order to maintain the stability of the wrist and provide certain force support, the extensor muscles (such as the extensor carpi radialis brevis, extensor carpi radialis longus, extensor carpi ulnaris) and flexor muscles of the wrist, as well as some muscles of the shoulder (such as the upper trapezius muscle) will also participate and cooperate to varying degrees.

[0007] During long-term typing, lifting the index finger when typing on the keyboard causes the muscle group mainly composed of the extensor digitorum of the index finger to be tense, which is likely to cause chronic strain. Typical symptoms include chronic aseptic inflammatory changes in the muscle tendon sheath mentioned above. Summary of the Invention

[0008] To solve the above drawbacks, the technical problem to be solved by the present invention is to provide an auxiliary finger cot that provides elastic assistance during typing and effectively reduces the tension of the muscle groups related to the index finger. To solve the above technical problem, the technical solution adopted by the present invention is an elastic assistance finger cot for auxiliary typing, which is characterized by including a proximal phalanx sleeve sleeved on the proximal phalanx of the index finger and a wrist sleeve sleeved on the wrist; the proximal phalanx sleeve is connected to the wrist sleeve through an elastic strip, and the elastic strip is distributed along the dorsal side and palmar side of the index finger; the elastic strip is provided with a tension adjustment mechanism so that the elastic strip is in an elastically stretched state in the preparatory typing state.

[0009] The beneficial effect of the present invention is that after wearing the elastic assistance finger cot of the present invention, the tension of the elastic strip is adjusted through the tension adjustment mechanism so that the elastic strip is in an elastically stretched state in the preparatory typing state. When hitting the keyboard or mouse, when the index finger is lifted, the elastic strip elastically contracts along the dorsal side of the finger to provide a backward and upward assisting pulling force; the working mode of the index finger changes from completely relying on active contraction to a mixed working mode of active contraction and passive contraction, which not only reduces the contraction strength of the extensor muscle of the index finger through assistance, but also effectively relieves the tension of the extensor muscle of the index finger and its auxiliary muscle groups, thereby reducing the incidence of chronic strain.

[0010] Preferably, the length of the proximal phalanx sleeve corresponds to the proximal phalanx, and the connection part of the elastic strip and the proximal phalanx sleeve is close to the middle phalanx. The assisting pulling performance is better and the comfort is better.

[0011] Preferably, the front end of the wrist sleeve is provided with a support pad for supporting the root of the palm. Further relieve the tension of the extensor muscle of the index finger and its related auxiliary muscle groups.

[0012] Preferably, the support pad is a salt pack. The salt pack composed of coarse salt or sea salt is convenient for arbitrarily adjusting its thickness and shape to adapt to the individual needs of the typist.

[0013] Preferably, the support pad and / or the proximal phalanx sleeve, the wrist sleeve are provided with electric heating elements.

[0014] Preferably, the support pad, the proximal phalanx sleeve, the wrist sleeve and their elastic strips are arranged at the corresponding parts on the glove. The glove can be a full-finger glove or a fingerless glove. It can also be a five-finger glove or a glove with less than five fingers. Preferably, one end of the elastic strip is fixed to the proximal phalanx sleeve, and the other end of the elastic strip is connected to the wrist sleeve through a tension adjustment mechanism, and the glove is provided with an inner cavity for accommodating the elastic strip.

[0015] Preferably, the cross-section of the end of the elastic strip close to the wrist sleeve is smaller.

[0016] Preferably, the tension adjustment structure includes positioning holes provided on the proximal phalanx sleeve and / or the wrist sleeve, and also includes a Velcro connection component provided on the elastic strip. The convenience is better.

[0029] Figure 6 It is a schematic structural diagram of Example 2 (palm of the glove). DETAILED DESCRIPTION OF THE INVENTION

[0030] Example 1: Refer to the attached Figure 1-4 , which reflects a specific structure of the present invention. The elastic assisting typing finger sleeve includes a proximal phalanx sleeve 1 sleeved on the proximal phalanx of the index finger and a wrist sleeve 2 sleeved on the wrist; the proximal phalanx sleeve 1 and the wrist sleeve 2 are connected by an elastic strip 3, and the elastic strip 3 is distributed along the back of the index finger and the back of the palm; the elastic strip 3 is provided with a tension adjustment mechanism.

[0031] In the example, the tension adjustment structure includes positioning holes 4 provided on the near finger joint sleeve 1 and the wrist sleeve 2, and further includes a Velcro connection component 5 provided on the elastic strip 1. In other embodiments, it may also be other mechanisms for adjusting the length of the belt body (such as a leather belt, a shoulder strap, etc.).

[0032] In the example, the length of the near finger joint sleeve 1 is set corresponding to the length of the near finger joint to improve the working stability and the comfort of pulling. The connecting part of the elastic strip 3 and the near finger joint sleeve 2 - the positioning hole 4 is close to the middle finger joint of the index finger. The assisting pulling performance is good and the comfort is good.

[0033] In the example, a support pad 6 for supporting the root of the palm is provided at the front end of the wrist sleeve 2. The position of the wrist is raised by about 1 - 1.5 cm. When used in cooperation with the near finger joint sleeve 1, the wrist sleeve 2 and the elastic strip 3, the comfort is further improved, the pressure on the hand muscles including the extensor digitorum can be reduced, and the tension of the extensor indicis proprius and its related auxiliary muscle groups can be further relieved.

[0034] After wearing the elastic assisting finger sleeve of the present invention, the tension of the elastic strip 3 is adjusted through the tension adjustment mechanism, so that the elastic strip 3 is in an elastic stretching state in the preparatory typing state. Specifically, in the example device, one end of the elastic strip 1 can be gently pulled to gradually stretch the elastic strip 1 to a degree that is comfortable but can still feel the pulling. During the initial use, it can be adjusted repeatedly during typing to adapt to the individual needs of the typist. When hitting the keyboard or mouse, first actively lift the index finger, and the elastic strip elastically contracts along the back of the finger to provide a backward and upward assisting pulling force; the working mode of the index finger changes from completely relying on active contraction to a mixed mode of active contraction and passive contraction. Not only can the contraction force of the extensor indicis proprius be reduced through the assistance, but also after the related muscle groups adapt to the passive assistance, the tension of the extensor indicis proprius and its auxiliary muscle groups can be effectively relieved, thereby reducing the incidence of chronic strain.

[0035] Example 2: Refer to the appendix Figure 5 、 6 , which reflects another specific structure of the present invention. The difference from Example 1 is that the support pad 6, the near finger joint sleeve 1, the wrist sleeve 2 and their elastic strip 3 are arranged at the corresponding positions in the glove 9. In the example, the glove 9 is a full finger glove, a five - finger glove. In other embodiments, it may also be a fingerless glove or a glove with less than five fingers (such as a glove with only the index finger). An inner cavity for accommodating the elastic strip 3 is provided in the glove to facilitate its free expansion and contraction.

[0036] In the example, one end of the elastic strip 3 is fixed to the near finger joint sleeve 1. The other end of the elastic strip 3 is connected to the wrist sleeve 2 through a tension adjustment mechanism. Specifically, the elastic strip 3 passes through a through - hole on the glove 9, and a number of positioning holes (not shown in the figure) are distributed along the length direction of the elastic strip 3 and are fixed on the positioning hooks (not shown in the figure) inside the wrist sleeve 2, similar to the structure of a leather belt.

[0037] In the example, the cross-section of one end of the elastic strip 3 close to the wristband 2 is smaller, making its elastic tension more in line with the need for typing assistance.

[0038] In the example, the support pad 6 is a sea salt pack attached to the palm root of the glove 9. The salt pack composed of sea salt particles is convenient for arbitrarily adjusting its thickness and shape to adapt to the individual needs of the typist. In the example, the support pad 6, the proximal phalanx sleeve 1, and the wristband 2 are provided with electric heating elements, and each electric heating element is electrically connected to the power supply 7 through a wire. The power supply 7 is provided with an electric switch 8. By heating, the blood circulation of the relevant muscle groups is promoted, and the tension is further relieved.
