Description

The present invention relates to a wrist supporter, and more particularly to a wrist supporter having a simple structure and enhanced wearing feeling and wearing strength.

Traditionally, wrist supporters have been used as a device to fix and stabilize the wrist, from the purpose of fixing and stabilizing the wrist during sports, to resting the wrist that is overworked in daily life, and in the recovery process of wrist treatment. Is also widespread. Since there is a great need for such wrist supporters, various types of improved wrist supporters are being developed one after another.

As a conventional wrist supporter, there is one that tries to increase the support strength by using an external member. For example, as an external member for fixing the wrist, for example, a splint made of a cushion material may be used in combination to reduce the burden of impact or the like together with the splint.

For example, in a wrist supporter having a thumb insertion hole in a band-shaped body and attached to the wrist using a hook-and-loop fastener as a hook-and-loop fastener, a covering portion that covers the back or palm of the hand and a winding portion that winds the wrist approximately once. A hook-and-loop fastener is provided on the surface of the strip-shaped body, the thumb insertion hole is provided at one end on the lining portion side, and the surface fastener faces the back surface of the strip-shaped body at the other end on the winding portion side. There is a wrist supporter to which a splint (for example, one formed of soft urethane foam) is fixed on the back surface of the wound portion (see Patent Document 1).

In addition to this, for example, as a conventional wrist supporter, there is also one specialized for various sports applications that require wrist fixation. For example, as a practice for learning or improving volleyball spike technique, the pad is placed on the pad that covers the surface on the back side of the wrist that extends from the back of the hand to the back of the wrist to the tip of the forearm. A finger strap to fasten the pad and a strap belt to fasten the pad to the tip of the forearm are attached, and the rigidity that prevents the dorsiflexion of the wrist is prevented between the outer outer material of the pad and the lining on the skin side. There is a wrist supporter that includes a rigid core material made of a flexible plate (see Patent Document 2).

However, in the conventional wrist supporter, for example, as in Patent Document 1 described above, the back of the hand is fixed by twisting upward or downward with the thumb inserted through the thumb insertion hole as a fulcrum. Since the twisted direction force acts to fix it, it also covers the back of the hand, but the back of the hand is not naturally fixed upward as it is, and such fixing of the back of the hand causes unnatural movement and discomfort for the wearer. There is a problem that it is difficult to obtain a natural wearing feeling.

Further, in Patent Document 1 described above, it is necessary to prepare an external member separate from the supporter main body by using an external member such as a splint for fixing the wrist, which complicates the manufacturing process. There is also the problem that the manufacturing cost increases. In addition, maintenance such as repair when the external member comes off from the main body is also complicated.

Further, for example, in Patent Document 2 described above, the wrist is merely fixed, and the purpose is to hit a sharp and intense spike in volleyball to prevent only the dorsiflexion of the wrist. It is not supposed to be used for other daily purposes, and is limited to limited use.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wrist supporter that can firmly fix the wrist and also fix the back of the hand in a natural state with a simple configuration.

The wrist supporter according to the present invention is a wrist supporter that is stretchably formed and is formed of a tubular body into which four fingers from the index finger to the little finger can be inserted, and the vicinity of the base of the inserted four fingers is formed. A finger accommodating portion for accommodating, a winding portion which is formed in a long shape extending from a tubular base end portion on the little finger side of the finger accommodating portion and which can be engaged and fixed while being wound around the wrist, and the above-mentioned The finger accommodating portion is formed so as to extend from the back side of the hand, and includes a back portion of the hand that engages with the winding portion located on the back side of the hand to fix the winding portion.

In this way, the finger accommodating portion accommodates and fixes the vicinity of the bases of the inserted four fingers so that the wound portion can be engaged and fixed in a state of being wound around the wrist, and the back portion of the hand can be engaged and fixed. Since the winding portion is fixed by engaging with the winding portion located on the back side of the hand, the back portion of the hand engages with the winding portion wound around the wrist on the back side of the hand. It is fixed to the winding part, and by this fixing, a tensile force that pulls the back part of the hand toward the wrist side acts, and this tensile force causes the vicinity of the bases of the four fingers housed in the finger storage part to face upward (the back side of the hand). The pulling force acts to maintain the horizontal state of the back of the hand, and the pulling force acts to keep the back of the wearer's hand in its natural state without twisting force, that is, in the horizontal state. The four fingers of the wearer are firmly fixed, and not only the wrist is fixed, but also the back of the hand extends from the wrist to the four fingers. It can be firmly fixed while maintaining its natural state.

Further, in the wrist supporter according to the present invention, the winding portion is parallel to the wrist cross section while orbiting the thumb ball from the tubular base end portion on the little finger side of the finger accommodating portion, if necessary. It is curved and extends to the end, and is formed in a substantially straight long shape from a position parallel to the wrist cross section.

As described above, in the wrist supporter according to the present invention, the winding portion is curved from the tubular base end portion on the small finger side of the finger accommodating portion while orbiting the thumb thumb ball until it is parallel to the wrist cross section. Since it extends and is formed in a substantially straight long shape from a position parallel to the wrist cross section, the wound portion circulates around the wearer's thumb and thumb ball, as described above. When a tensile force that pulls the back of the hand toward the wrist acts, it acts as an anchor that firmly supports this tensile force, and since the wound portion avoids the wearer's thumb, the anchoring action is performed. Without putting a burden on the thumb, a force to pull the finger accommodating portion upward (in the direction from the palm side to the back side of the hand) is exerted, and this anchoring action and the tensile force act in an overlapping manner to move upward. Due to the pulling force generated, the wearer's four fingers are also firmly fixed by receiving the upward pulling force, and not only the wrist is fixed without using an external member, but also the four fingers are pulled upward. The four fingers can also be firmly fixed.

Further, in the wrist supporter according to the present invention, the tubular body that accommodates the four fingers of the finger accommodating portion becomes higher as necessary from the little finger side toward the index finger side. As described above, in the wrist supporter according to the present invention, since the tubular body accommodating the four fingers of the finger accommodating portion becomes higher from the little finger side toward the index finger side, the wrist is not only fixed but also described above. The four fingers housed in the finger housing fit the size of the wearer, and the back of the hand keeps the back of the wearer's hand in its natural, or horizontal state, without any twisting force. However, it will be pulled straight up without shaking, and it can be fixed while maintaining the natural state of the back of the wearer's hand according to the size and range of movement of the wearer's four fingers, and the wearer. The wrist can be firmly fixed.

Further, in the wrist supporter according to the present invention, if necessary, at least a part of the back of the hand facing the winding portion and at least a part of the winding portion are male and female surfaces. It is formed as one of the fasteners. As described above, in the wrist supporter according to the present invention, at least a part of the back portion of the hand facing the winding portion and at least a part of the winding portion are either male or female hook-and-loop fasteners. Since it is formed as a hook, it can be easily attached and detached while maintaining a natural supporter shape when attaching and detaching the wrist supporter regardless of the size of the wearer's wrist, which enhances the convenience of attachment and detachment and makes the wearer's wrist easier to attach and detach. Can be firmly fixed.
