JP5570039B1 - Sleep ankle stretch device - Google Patents

Abstract

[Objective] Bedridden severely handicapped and disabled people tend to harden muscles and joints, and family and caregivers need to perform ankle massage or stretch exercise frequently and can support it There were no tools or equipment.
SOLUTION: Even if the user himself / herself is sleeping on the back for reasons that make it difficult to move, a family or caregiver other than the user can easily obtain a safe and stable stretch effect only by operating the handle. It can reduce the fatigue of family members and caregivers.

Description

  The present invention relates to an apparatus for stretching an Achilles tendon or an ankle while lying on its back.

  Conventional tools and devices for stretching the Achilles tendon have been sufficient to stretch by themselves using their own weight from the sitting state, or by stretching their Achilles tendon or ankle by themselves.

  The problem to be solved is that a person who is difficult to maintain a standing state or a sitting position because of physical inconvenience, bedridden, or an elderly person cannot easily perform the exercise of extending the Achilles tendon.

In order to solve the above-mentioned problems, the first invention facilitates a stretching exercise that pushes the sole of the foot using a device installed on the foot while the stiff Achilles tendon and ankle joint are lying on their back Stretch device characterized by being safe and stable.
Further, the second invention is a stretch device characterized in that an angle adjusting function for determining an angle at the time of stretching is provided at a portion where the sole contacts.

According to the first invention, the structure can be made compact in size, so that it can be installed at a narrow foot, and since the expansion / contraction stroke for pressing the sole is long, there is an advantage that the stretch effect is great. A user in a posture lying on his / her back can easily perform a stable Achilles tendon stretching exercise without moving.
Alternatively, according to the second invention, there is an advantage of more effectively softening and preventing the stiffness of the Achilles tendon and the ankle joint by the stretch effect by adjusting the angle of the portion in contact with the sole.

It is the top view and side view which showed one Embodiment of this invention.

One embodiment of the present invention is shown in FIG.
The material of the stretch device is made of metal, and the rectangular installation surface B1 is fixed and used in the gap between the sole of the user lying on his back on the bed and the bed. When a caregiver or the like other than the user rotates the disk-shaped handle A1, the connected male screw A2 rotates, and C1, which also serves as a female screw combined with the male screw A2, is changed according to the number of rotations of the handle A1. Move the range straight. The arm D connected to C1 expands and contracts with the axis E as a fulcrum, pushes and moves the B2 portion and the C2 portion, and pushes the sole with the movable plate F constituting the sole angle adjusting mechanism.

"Effect of the embodiment"
According to this embodiment, the surface F with which the sole touches while lying down can freely adjust the angle of the sole placement surface by fixing the hole H2 provided for adjusting the angle with the axis G as a fulcrum. Can be adjusted. It can be stretched according to the user's Achilles tendon, ankle joint and body condition, so it is safe and secure.

Claims (2)

It is a stretch device that can easily and safely perform a stretching exercise that pushes the sole of the foot using the device installed at the foot while keeping the Achilles tendon and ankle joint that have become stiff on the back ,
In order to install the device, a fixed part (B1) for fixing to the rising part of the end of the bed and a position inside the bed of the fixed part (B1) are arranged on the sole with an angle of stretch. A movable plate (F) in contact with the movable portion (F1), and an expansion / contraction mechanism that expands and contracts with a stroke to linearly move the movable plate (F) with respect to the fixed portion (B1) to fill a gap with the sole. And
The expansion / contraction mechanism is provided at a portion inside the bed of the fixed portion (B1) for rotating the male screw shaft (A2) held parallel to the rising portion and the male screw shaft (A2) about the axis. And an X-shaped link mechanism in which two arms (D) having the same length are linked to each other so as to be rotatable around a central axis (E) in order to perform expansion and contraction by the rotation. Of the four end portions of the X-shaped link mechanism, one end portion on the rising portion side is pivotally linked to the holding portion (H) and the first end shaft (S1). The second end shaft (S2), the other end of which is on the side of the rising portion, is rotatably coupled to the female screw portion (C1) that is screwed into the male screw shaft (A2) and moves linearly with the rotation. ) And one end of the inside of the bed A third end shaft (S3) that is rotatably linked to the movable plate (F) at a position facing the end shaft (S1), and the other end inside the bed are the second end shaft. A fourth end shaft (S4) that is pivotably linked to a moving part (C2) that similarly moves linearly in a similar manner to the female part (C1) that moves linearly at a position facing (S2); A stretch device characterized by comprising:   The stretch device according to claim 1, wherein the stretch device is provided with an angle adjusting function for determining an angle at the time of stretching at a portion where the sole touches.
