Description

The present invention provides continuous support for people whose range of motion in their finger joints has become narrowed due to age or illness, making it difficult for them to move or work using their fingers. It relates to mittens as an auxiliary tool that enables work.

Conventionally, there have been dedicated auxiliary tools for each task, but it is necessary to replace the auxiliary tools each time the task changes in a series of tasks, and this is done with assistance or support.

In the prior art, there are specialized auxiliary devices equipped with a mechanism for transmitting gripping force, specialized mittens that are used over the hands, and tools intended to compensate for lacking functions.

In other words, it is possible to work by preparing special aids for each task and changing them while working, but it takes time to change them, and it is necessary to receive assistance and support for aids that are difficult to change by oneself. There is.

The present invention provides mittens that make it possible to perform continuous work using everyday tools while changing hands.

The mittens of the present invention are small enough to fit inside the palm of the hand, and can perform pinching motions instead of fingers and grasping motions instead of hands, and can be used with common everyday tools and utensils while changing hands. Allows continuous work to be done.

The mitten according to the present invention is an auxiliary tool made of a soft and elastic material, and is equipped with a two-pronged gripping part for gripping objects, and after holding and fixing a cap or lid in the center of the gripping part, the mitten can be used to hold a bottle or bottle. By turning it, you can tighten and loosen it, and then use the two-pronged grip to grasp the cap or lid, allowing you to lift it up and remove it in succession.

An embodiment of the present invention will be described based on the accompanying drawings.

Figure 1 is a front view of the mitten (1) worn on the hand with the gripping surface (3) closed, Figure 2 is a side view of Figure 1 seen from the gripping side, and Figure 3 is the mitten (1). 4 is a front view of the state in which the grip surface (3) is opened when worn on the hand, and FIG. 4 is a side view of FIG. 3 viewed from the grip surface side.

FIG. 5 is a front view of the mitten (1), FIG. 6 is a side view of FIG. 5 viewed from the mounting surface side, and FIG. 7 is a side view of FIG. 5 viewed from the gripping surface side.

The mitten (1) of the present invention is an auxiliary tool that is sized to fit inside the palm and is made of soft and elastic resin material such as rubber such as fluororesin or foamed material such as urethane resin. This is an auxiliary tool that can be raised and folded in half from the center, allowing you to pinch and grasp objects with less finger movement.

Furthermore, the gripping action of the mitten (1) is performed by bending the metacarpophalangeal joint of the hand on which it is attached, and the symmetrical, opposing slopes, which are thinnest at the center of the bend and thicken toward both ends, form a double-crested shape. An auxiliary tool with a fixed grip.

Furthermore, the mounting surface (2) of the mitten (1) that comes into contact with the palm side has the thenar relief surface (7) and the little foot relief surface (8) diagonally so that the carpus relief surface (6) can be used for positioning. An auxiliary tool with a three-dimensional shape with a relief cut.

Furthermore, the mounting surface (2) of the mitten (1) that contacts the finger side has a release surface on the index finger side so that the tip of the middle finger can be caught on the fingertip hooking surface (9) and pressed with the tips of the index finger and ring finger to position and fix. (10) and ring finger side relief surface (11) are shaved obliquely to provide an auxiliary tool with a three-dimensional shape.

Furthermore, the shapes of the carpal relief surface (6) and the fingertip hooking surface (9) are made symmetrical with respect to the bending position, and the shapes of the palm-side attachment (4) and the finger-side attachment (4) are also made symmetrical. By making it symmetrical with respect to the bending position, there is no directionality to insert it, making it an auxiliary tool that can be used for both left and right hands.

Furthermore, in order to ensure that the gripping surfaces (3) are in close contact with each other when the mitten (1) is bent, a gripping relief groove is provided in the center of the gripping surface (3) as a space to release the portion that bulges and deforms due to the bending operation. (5) Auxiliary equipment equipped with.

Furthermore, in order to securely fix and grip objects, the gripping surface (3) has multiple small cavities inside, and when an object is grabbed and applied to the gripping surface (3), the cavities deform and the gripping surface (3) is an auxiliary tool for gripping that has a double peak shape that follows the shape of the object.

Furthermore, for storage when the mittens (1) are removed, prepare a stand with a triangular prism in the shape of a mountain that matches the shape of the grip and place it on its side, and place the grip of the mitten (1) together. The mounting surface (2) is positioned in a horizontal position, and is an auxiliary tool that can be easily inserted into and removed from the ring-shaped mounting tool (4).

The usage and function of the mitten (1) in one embodiment will be explained.

Figure 8 shows a posture in which the mitten (1) is used to hold the eating utensil facing inward towards the thumb side. You can enjoy eating by holding the functional parts of your fork, knife, etc. with your thumbs facing toward you, and switching to the appropriate utensil for the dish.

Figure 9 shows a posture in which a writing utensil is held outward toward the little finger side using a mitten (1).In office work, the posture is mainly directed towards office supplies, such as a ballpoint pen (22), etc. You can hold the functional parts of correction fluid, pencils, erasers, etc. with your little finger facing towards you, and continue working with less strain while switching to the necessary tools.

Figure 10 shows how the cap (23) is tightened and loosened using the mitten (1), and Figure 11 shows how the cap (23) is gripped and lifted to attach and detach. After holding and fixing the cap (23) from above in the center of the grip, the bottle (24) can be tightened and loosened by rotating, and then the cap (23) can be tightened and loosened using the grip surface (3) of the mitten (1). It can be gripped and lifted to attach and detach.

In the actions that people perform, there are two postures: one in which the tool is used toward oneself, and the other in which the tool is used toward an object.If there is a degree of freedom in the posture in which the tool is held, it is possible to respond to a variety of movements. Furthermore, using common everyday tools and tools, it becomes possible to perform continuous tasks by combining movements while changing hands.

By using the mittens of the present invention, people who have quit their jobs due to difficulty in using their fingertips will be able to do office work and light work, increasing their opportunities to work in jobs that are less physically demanding, and increasing their chances of working in society. This can contribute to the problem of labor shortage.
