Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a forearm support for people with walking disabilities. More specifically, the present invention relates to a forearm support part that can freely adjust and fix the inclination angle of the forearm support part with respect to the nine gripping hands.

Prior Art> Fig. 3 shows a conventionally known forearm support. This forearm support part is a cane used by people who have a walking disability due to stroke or the like to walk while having their forearms supported. As shown in FIG. 3, this forearm support part is composed of a column 10, a forearm support part 20, and a clenching hand 30, which are fixed to each other at a connecting part, and the varus relationship of each part is fixed constant. ing. That is, normally, the support column 10 and the grip hand 30 are fixed at a right angle, and the forearm support part 30 is fixed at an angle of 15 degrees with respect to the extension line of the support column 1O, that is, 105 degrees with respect to the grip hand 20.

This known forearm support allows a disabled person to walk freely on a flat road by resting his or her forearm on the 15° inclined forearm support 20 and grasping the hand grip 30. Helpful. However, this known forearm support
This has the disadvantage that it places a great burden on the disabled person when he or she climbs a slope or stairs, or when the stool stands up from a sitting position. In other words, with known forearm supports, people with disabilities have to lift their shoulders and elbow joints more than necessary when climbing slopes or stairs, while with stools, when standing up from a sitting position, they have to lift their shoulders and elbows more than necessary when climbing slopes or stairs. It is necessary to lift the elbow joint, and the person with a disability is required to use more strength than normal because he or she cannot effectively exert force to support the cane and raise the body.

These can cause great suffering to disabled people, and require great care and skill for disabled people to act under these conditions.

In addition, even in the conventionally known forearm support part, as shown in FIG.
25 are provided. These length adjustment +1A purchase 15,
25 is provided to match the height and forearm length of a disabled person when the forearm support part is used on flat ground, and is always kept constant for the disabled person. And the length adjustment S iso register 15.25 is usually a mechanism that is adjusted with both hands, so it is not something that can be easily adjusted on the spot while in use, for example when trying to go up the stairs, but it corresponds to the above-mentioned conditions. It's not possible.

The inventors of the present invention have conducted extensive research on the structure of the forearm support that is suitable for all types of movements in the daily lives of disabled people, and have determined that the angle of the forearm support with respect to the extension line of the support is 15° when walking on flat ground. If the hill of a slope or staircase is 45 degrees, and the length of the armrest is 900 degrees when standing up from a sitting position, it is possible to exert the power of walking most efficiently, and the forearm support is the easiest for disabled people to use. The present invention was achieved by discovering that this is the case.

OBJECTS OF THE INVENTION The object of the present invention is to provide a forearm support 8' that overcomes the drawbacks of conventionally known forearm supports and can be adapted to all movements of the daily life of a disabled person.

<Structure of the Invention> The object of the present invention is to connect a WD hand, a support column connected substantially perpendicularly to the gripping hand below a connecting portion provided at the end of the gripping hand, and a support in the front connecting portion. and a forearm support part, one end of which is rotatable with respect to the grasping hand, and a forearm support member is provided at the other end, through a bearing mechanism provided in the bearing mechanism. is provided with a locking mechanism that locks the inclination angle of the forearm support portion with respect to the gripping hand at a plurality of predetermined angles, and the gripping hand is provided with locking and releasing means that releases the locking mechanism. This is achieved by a forearm support featuring:

The plurality of predetermined angles are 105°, 135° and 180°.
° (1 if expressed as the angle of the forearm support to the extension line of the column)
(equivalent to 5°, 45°, and 90°) is suitable for all activities of daily life for disabled people, such as climbing on flat surfaces, slopes and stairs, and standing up from a sitting position. A fjl jli support cane is obtained.

If the connection between the connecting part of the father's front arm and the support is configured by a removable connecting rock groove, the combination of the forearm support part, Mp hand, and support can be combined with other body holding members such as an R-shaped grip. Can be changed to a combination of struts. By configuring the forearm support part in this way, the degree of disability of the disabled person will be reduced, and when the person becomes able to walk on one hand, the support can be shared, which is convenient for the disabled person and also economical. This can reduce the burden on employees.

<Example> The present invention will be described in detail below with reference to accompanying drawings showing an example of the forearm support part according to the present invention.

FIG. 1 shows a longitudinal cross-sectional view of the main parts of an embodiment of the forearm support according to the present invention. As shown in FIG. 1, the forearm support section according to the present invention is composed of a support column 1o, a forearm support member, and a hand grip. Although not shown in FIG. 1, a column main body 13 and a QfJ arm support member 23 are provided below the column 1o and above the forearm support part 20, as shown in FIG.

Ru.

The main bodies of the forearm support column, the forearm support part 2, and the gripping hand 30 are usually made of light alloy pigs in order to reduce the weight of the forearm support part. A connecting portion 31 is provided at the end of the gripping hand 30, and a male screw 33 is connected below the connecting portion 31. On the other hand, a norag 12 having a female thread is fitted above the light alloy pie f11 of the support 10, and by screwing the male thread 33 of the connecting portion 31 into the female thread of the support 10, the support 10 and the handle 30 are connected. Detachably connected.

A joint 24 is fitted into the light alloy motherboard 22 of the forearm support portion 20. - B11 of connecting part 31 of Manzu 9 hands 30
A shaft 32 extending substantially perpendicular to a plane including the axis of the column 10 and the axis of the gripping hand 30 is fixed to the 1 wall.
A joint 24 of the forearm support portion 2o is pivotally connected to the forearm support portion 2o.

Therefore, the forearm support 6' can be rotated about the axis 32 within the plane. The outline of the end of the joint 24 on the side pivoted to the shaft 32 is made into a semi-cylindrical shape, and the surface 25 of this semi-cylindrical outline has a diameter of 30 mm with respect to the axis of the shaft 32.
Three truncated conical recesses 26m, 26b and 26c of the same shape are provided at angular intervals of 45° and 45°.

On the outer periphery of the gripper 32 of the gripping hand 30 made of metal resin, a gripping outer cover is provided which is shaped to be easy for handicapped people to grasp, while on the inside of the gripper 32, the forearm support part is set at a predetermined angle of inclination. A locking device 4 and a locking/releasing means are provided for locking at and completely releasing the lock when changing the inclination angle. That is, as shown in FIG. 1, the first locking par 33 and the second locking
35 is a bearing 38 fixed to the inside of the arm 32,
39, and the first locking groove 33 and the second
The locking bar 35 is connected by a push/pull link mechanism 40.

The right end of the first locking member 33 in FIG. c.
A truncated conical engagement end 34 is formed in a shape that can be easily engaged with the second locking par 35. At the left end of the second locking par 35 in FIG. A compressed sedge ring 37 is provided between the fixed, locking and actuating methane 36 and the bearing 39. Therefore, normally the second locking bar 35 is biased +1 to the left in FIG. In Figure 1, it will be biased to the right. Therefore, as shown in FIG. 1, the forearm support section 20 located at the position indicated by A (hereinafter, the forearm support section located at position A is indicated by 21m) is securely fixed at that position. In this embodiment, the inclination angle α between the forearm support part 21a and the gripping hand 30 is 105° (the forearm support part 21
The angle between a and the extension of the support lO is 15°).

As shown in FIG. 1, the push-pull link mechanism (Tomoe) in this embodiment includes a fixed shaft 41 fixed perpendicularly to the longitudinal axis of the grip hand 30 at approximately the center of the grip hand 30; Two links 42° 43 are rotatably arranged to cross each other around 41, and two links 42, 43.
The opposite end of the fixed shaft 41 of the first locking par 33 is connected to the left end of the first locking par 33 in FIG. -35 1st
It is constituted by four links (44m, 44b, 45a, 45b) that rotatably connect the right end in the figure. Therefore, when the second locking pawl 35 is slid to the right in FIG. , 44b, 45a, 45b) expands in the vertical direction in FIG.
3 will slide to the left in FIG. As a result, the first
When the engagement end 34 at the tip of the locking bar 33 is disengaged from the recess 26a of the joint 24 of the forearm support 20, the forearm support 20 can be freely rotated with respect to the column 10 and the gripping hand 30. be able to move.

The push/pull link mechanism 40 is not limited to the configuration shown in FIG. It is sufficient to provide a mechanism 41' that can disengage the engagement end 34 of the locking par 33 from the recess of the joint 24.

Next, a method of using the forearm support portion according to the present example will be explained. Unless the locking bar actuating button 36 is pressed as described above, the engaging end 34 of the first locking bar 33 will slide into the recess 26 of the joint 24.
The forearm support portion 21a is reliably rectangular at the position A since the forearm support portion 21a is engaged in a state in which it is pushed into the portion a by the compression ring 37. The forearm support part in this state is used when walking on flat ground. When a person with a disability climbs a slope or stairs, the engaging end portion 34 is disengaged from the recess 26g by pushing the locking/guiding a7Ip button 36 with a fingertip. As a result, the forearm support 20 becomes rotatable, so that the forearm support 20 can be placed in the position indicated by B in FIG. 1 by moving the forearm. A recess 26b is provided in the portion of the joint 24 of the forearm support portion 21b placed in position B that faces the first locking par 33.
is provided, so press the correct bar operation button 3 at that position.
6, the locking end 34 engages with the recess 26b and fixes the forearm support 21b in that position. At this time, even if the inclination angle movement of the forearm support part 20 by the disabled person is more or less than iB, since the locking end part 34 and the recess 26b are made in the shape of a truncated cone, it will not be guided by the tapered part. It will be fixed at a predetermined position B.

Since the concave portion 26b is arranged 35 degrees off from the concave portion 26a, the position of the forearm support portion 21b is 135 degrees from the gripping hand 30.
45 degrees from the extension line of the strut 10. This is a per-piece design that allows people with disabilities to lock the stool in the same way when standing up from a sitting position.
J? The forearm support portion 21c is in position C when the tongue 36 is activated.
The person with a disability is able to effectively use the strength of his or her arms to stand up. The recess 26c is further 45 mm from the recess 26b.
Since they are arranged at different degrees, the forearm support part 21c is positioned opposite to the gripping hand 30 -11111, and is straight from the support 10. ■■------It will be in the position of 1st corner. As described above, the forearm support part according to the present invention can freely change the position of the forearm support part with respect to the gripping hand by the touch operation of moving the forearm while pressing the locking part activation button 36f. Since the forearm support part 21c is only pushed downward when the forearm support part 21c stands up from the ground, there is virtually no need to provide the recess 26e for locking.

Considering that the means for activating the locking R-activation detent 36 after the disabled person stands up is omitted, it is more preferable to configure the locking mechanism so that it does not operate on the forearm support portion 21c. Therefore, the forearm support arm according to the present invention is
Two recesses 26 a F 26 b are formed at an angular interval of 30° on the forearm so that the inclination angle (α) relative to the grasping arm of 0 can be locked at 105° and 135°. Forearm support 20 is provided on the surface of the cylindrical contour 25, and in the case of an inclination angle of 180°, the forearm support 20
The positioning may be performed by bringing the lower surface of the support column 10 into contact with the upper end portion of the support column 10.

If the degree of disability in mobility of a person with a disability has been reduced and he or she is able to walk through T School, the third
As shown in the figure, connect the male screw 51 of the T'f-grip 50 to the support 10! By screwing into the female thread of the lug 12, the strut 10 can be used in common with a forearm support.

Since it is possible to switch between the T school and the forearm support part at any time according to the activities of the disabled person in daily life, it is convenient for the disabled person and also helps to lighten the economic burden.

<Effects of the Invention> Since the forearm support part according to the present invention has 14 parts as described above, the inclination angle of the forearm support part with respect to the grip υ part can be adjusted so that it can be adapted to all movements of the daily life of a disabled person. can be freely changed with a single touch, and the forearm support is reliably fixed at each position. Therefore, by using the forearm support according to the present invention, a disabled person can safely and easily cope with all activities of daily life.
