JP5966163B2 - Wheelchair footrest that can move your foot - Google Patents

Description

  For those who cannot walk and live in wheelchairs, feet placed on footrests while riding so that the means of transportation can continue to ride on the main purpose wheelchair for a long time It is about the footrest of the wheelchair which thought that it can move.

  Those who have difficulty walking not only live on the bed but also enjoy life in a wheelchair for a long time, especially in nursing homes, etc. Many people get together at the same place and enjoy various entertainment while riding in a wheelchair for a long time.

  Although the current wheelchair is devised in various ways, such as riding comfort and foot placement, the footrest plate of the footrest has only the function of placing the foot on any wheelchair, and the foot that has been on for a long time is moved There is nothing.

  If it is difficult to move your foot on your own, you will need assistance such as getting a massage of your foot, moving it, or helping you get on and off the wheelchair.

The following patent documents disclose a footrest angle adjusting mechanism and a footrest turning and opening / closing device.
JP2008-279240 JP2007-252859

  In addition to the angle adjustment and turning / opening and closing devices described above, the published patent literature relating to wheelchair footrests includes many functions such as footrest detachment function, height adjustment, footrest position change, prevention of pinching of footsteps, and devices capable of passing through step areas. However, there is no function to move the foot placed on the footrest.

  For those who have difficulty walking, the weakness of the foot is occurring and the degree of disability is different, so you can select the stimulus according to your degree of disability without giving a stimulus that puts an excessive burden on the foot Thus, there is a need for a device having a structure that is different from the way of giving a stimulus instead of a single structure.

  If you are riding on a wheelchair for a long time, you will not move your foot at all during that time, so your foot will remain stationary for a long time, poor circulation, swelling of the foot, ankle contracture, orthostaticity In addition to the drawbacks of promoting symptoms such as hypotension and economy syndrome, there are many problems such as feeling pain because the entire lower body does not move in the same posture.

  In order to solve many of the above problems while riding in a wheelchair, it is necessary to move the muscles of the legs (especially the gastrocnemius and soleus muscles) and the ankles with power.

  If a person in a wheelchair pushes the switch on the spot to move the power and the movement is not transmitted to the foot, an assistant for moving the foot with the power is required.

  In order to prevent the cuspid contractures feared by wheelchair consumers, it is necessary to convey the movement in the direction opposite to the heel direction to the feet.

  In order to enjoy life while riding a wheelchair for as long as possible, it is necessary to add a new function to the wheelchair that improves blood circulation of the legs that are stationary while riding and enables muscle activity.

  In the foot, it is the sole that feels and is most effective when it receives a moving stimulus, so there is a stimulus that moves the foot using a footrest plate that is in contact with the sole while riding in a wheelchair. To be given.

  If the entire footrest plate is moved, the entire foot that is placed will move, so there is a risk that the foot will fall off the footrest plate, and there is a risk that the foot with the obstacle will be overburdened. Avoid moving the entire footrest.

    Therefore, while keeping the foot resting on the wheelchair, the foot is currently placed so that it can convey the moving stimulus to the muscles and joints of the foot by stimulating part of the sole with power. A "moving footrest board" that has a function that can be moved by power is newly attached to the fingertip part on the extension line of the stationary footrest board or the position of the heel part with a joint tool. It is possible to make a “combination footrest plate” and to move only the “movable footrest plate” upward and downward from the extension line of the “stationary footrest plate”, and to move this up and down movement in a variable cycle. A wheelchair footrest characterized by:

  The moving footrest plate can be attached to either the position where the fingertips touch or the position where the heel hits, or the person who is riding on both the fingertips and heels can select and move Three kinds of things that can be.

  The device that moves the moving footrest plate can be installed on the wheelchair itself so that you can receive a stimulus to move your foot when you switch on your own while you are in the wheelchair, without the help of an assistant. take in.

  Because it receives stimulation that moves at the sole of the foot, it can move the muscles and joints and get a stretch effect while feeling the comfortable foot feel like a massage with a small burden on the foot You can change your mind and feel free from the pain of riding in a wheelchair for a long time.

  Because you can loosen your feet at any time without help from a helper while in a wheelchair for a long time, you can continue to enjoy entertainment while riding in a wheelchair for a longer time than before, and a wheelchair by an assistant The number of times of getting on and off will also decrease.

  The new “combination footrest plate” is a combination of a “stationary footrest plate” and a “moving footrest plate”. Just being stimulated, no excessive pressure is applied to the muscles and joints, and slipping of the foot can be kept to a minimum.

  When the moving footrest plate attached to the fingertip part is moved, the fingertip part is lifted in the opposite direction to the apex direction, which prevents the cuspid contracture that is solidified with the ankle stretched. It has the effect of efficiently moving the muscles (especially gastrocnemius and soleus).

  On the other hand, moving the footrest plate attached to the position of the heel part gives the same natural movement as a healthy person sitting and poorly shaking, and the feet are rhythmically relaxed comfortably, with heels A sense of rhythm is transmitted to the brain and life in a wheelchair becomes comfortable.

  Up until now, wheelchair consumers have only been able to move the upper body, but now it is possible to move the lower body, and the pressure between the thigh and the wheelchair seat changes, reducing pressure ulcer and preventing pressure ulcers. Can be planned.

  A wheelchair is originally a care product that is used as a means for moving, but adding a function of moving a foot while riding on the wheelchair increases the value of using the wheelchair as a means of enjoying life.

  Even in a wheelchair that is already in use, the function of the wheelchair in use can be improved by replacing only the footrest part with a combination footrest.

Conventional footrest Attaching a support post and a rotating ring to place a moving footrest Position to attach the moving footrest to the stationary footrest The moving footrest is moving

BEST MODE FOR CARRYING OUT THE INVENTION

  A stationary footrest is attached by attaching a "combined footrest plate" that is a combination of a "movable footrest plate" that can be moved by power to the "stationary footrest plate" of a footrest that only has the function of placing a foot. An example of a footrest in which the entire sole is placed on both the board and the moving footrest board is shown below.

  As shown in FIG. 1, the conventional footrest is simply a stationary footrest plate 2 attached to a footrest plate attachment pipe 1, but as shown in FIG. 2, the footrest plate attachment pipe 1 is extended, A support column 3 for mounting a moving footrest plate 5 is attached to the pipe.

  A rotating ring 4 having a protrusion with a rotating ball or the like attached to the tip is attached to the central portion of the attached support column 3.

  As shown in FIG. 3, the newly moving footrest plate 5 is placed on the surface extension line of the stationary footrest plate 2 on the support column with the rotating ring, and is not attached to the footrest plate mounting pipe 1. The stationary footrest plate 2 fixed to the attachment pipe is connected with a joint 6 such as a hinge so that the entire sole is placed on the surfaces of the connected footrest plates.

  The mounting position of the moving footrest plate can be selected and moved by either the position where the heel hits or the position where the fingertip hits, or the person riding on both the fingertip and heel Three types of things that can be done.

  As shown in FIG. 4, when the rotating ring 4 is rotated by power, the moving footrest plate 5 uses the joint with the stationary footrest plate 2 as a fulcrum, and the side opposite the fulcrum is pushed up by the length of the projection. It moves diagonally up and down.

  Wheelchair footrest with a structure that moves the moving footrest plate when the person on the wheelchair pushes the switch at any time. And
