JPH03292956A - Stick for handicapped person - Google Patents

Abstract

PURPOSE:To allow a handicapped person to easily take an easy posture when he sits down and to also easily apply force to a stick when he stands up from a chair or goes up the stairs by integrally revolving a grip lever and a forearm support lever with respect to a main lever. CONSTITUTION:At the time of walking, a stick 1 is set to a walking state and the forearm is passed through the space of a forearm support device 30 from above and the grip 34 of a grip lever 4 is gripped by the hand. since the forearm support lever 5 is fixed to the forearm, the stick is not shaken to permit safe walking. When a handicapped person sits down on a chair or bench, he brings down the forearm support lever 5 rearwardly while pulling operation lever 26 to bring the same to a sitting-down state. The lever 26 can be easily drawn near by hooking a forefinger with the lever 26. Since the forearm support lever 5 and the grip lever 4 are mutually fixed at an almost right angle and integrated, the grip lever 4 becomes a rising state. Therefore, the grip lever 4 can be gripped as it is at the time of sitting down and force is easily applied to the stick in a downward slightly oblique rear direction at the time of the standing-up from a chair and standing-up operation is easy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cane suitable for use by a physically handicapped person who has difficulty walking.

[Prior art] Especially when a walking disabled person with limb impairment due to a stroke or the like uses an auxiliary cane, it is better to fix the cane to the forearm than to simply hold the cane in the hand to prevent the cane from wobbling. It is easy and safe to walk.

For this reason, canes for physically disabled people are used that are provided with a grip lever for gripping with the hand and a forearm support rod for supporting the forearm. Note that this type of cane is generally equipped with a forearm fixing device for fixing the forearm to the forearm support rod.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional cane, the main rod, grip rod, and forearm support rod were fixed to each other, and the mutual angle of each rod was always constant, so it was difficult to walk on flat ground. This was fine, but it was very inconvenient because my elbows were unnaturally raised when I went up the stairs or when I sat on a chair.

In order to solve this problem, as proposed in Japanese Patent Publication No. 63-29548, the main rod (also referred to as ``post'' in the publication) and the grip rod (also referred to as ``grip hand'') should be replaced with a forearm support rod (also referred to as ``hand grip''). A cane with a forearm support part that can be tilted backwards has been considered, but since the grip of this cane is fixed to the main rod, if you keep holding the grip while sitting on a chair, your wrist will fall. There was also the problem that the forearm was twisted, causing pain, and that the user was unable to apply sufficient force to the cane when standing up from the chair.

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration.

That is, 1. the cane for physically disabled persons according to the present invention includes a grip rod to be gripped by hand, a forearm support rod for supporting the forearm, and a main rod whose lower end is brought into contact with the ground, and the grip rod and the forearm support rod are are fixed approximately at right angles to each other.

The joint between the grip rod and the forearm support rod changes from a state in which the grip rod protrudes forward and the forearm support rod protrudes upward relative to the main rod in an upright state, to a state in which the grip rod protrudes upward and the forearm support rod protrudes backward. It is characterized by being connected to the upper end of the main rod so as to be rotatable within the range of .

[Function] The grip rod and forearm support rod are designed to rotate integrally with respect to the main rod, so when the forearm support rod is tilted backwards when sitting on a chair, the grip rod stands up. becomes.

For this reason, the user can take a natural posture while sitting on the chair without twisting the wrists or forearms, and since the gripping rod and the main rod are located almost on the same line, it is easy to put pressure on the cane when getting up from the chair.

Also, when the grip rod is rotated to the upper limit position, in other words, when the forearm support rod is tilted backward, the angle between the forearm support rod and the main rod should be slightly smaller than 90 degrees. When you sit on a chair, etc., the lower end of the main rod is located further back than the upper end, and you can stand up with the main rod slightly tilted forward, so when you stand up, you can apply a sufficiently large force downward. It can be added to the position, making it easier to stand up.

Furthermore, when the pin for fixing the angle between the main rod and the grip lever is fitted into the recess, the pin is inserted deeper into the recess than the center of rotation of the main rod and the grip rod. There is no rattling between the rod and the grip, resulting in an excellent feeling of use.

Furthermore, if the pin is moved forward and backward using an operating lever that protrudes downward from the tip of the gripping rod, it is easy to fix and release the main rod and the gripping rod.

[Example] The embodiments shown in the drawings will be described below.

1 to 5 show an example of a cane according to the present invention. This cane 1 has a main rod 3 made of a light alloy pipe extending radially around a pivot portion 2. It includes a grip rod 4 and a forearm support rod 5.

The pivot portion 2 includes a first pivot member 7 fixed to the upper end of the main rod 3 and having a concave shape in front view, and a second pivot member 8 that is a common base of the grip lever 4 and the forearm support rod 5. They are mated. The grip rod 4 and the forearm support rod 5 are fixedly integrated with each other, and the angle θ between them is 1! is slightly larger than the right angle.

This angle θ is preferably about 93 to 100 degrees, more preferably about 97 degrees.
Each company is screwed to the first and second pivot members 7, 8, respectively, by screw members 3a, 4a, 5a fixed at an angle of 4.5°. Further, a round rod-shaped retaining member 11 having a recess lO opening in the grip lever 4 is attached to both vertical parts 7a, 7a of the first pivot member 7 while horizontally penetrating the second pivot member 8. and is fixed with stud bolts 12.12. The second pivot member 8 is provided with a through hole 15 that connects the hollow portion of the grip lever 4 and the retaining member through hole 14 of the first pivot member 7. 16 is inserted. The retaining pin 16 is slidably fitted into a split bush 18 fixed to the screw member 4a, and is urged toward the pivot portion by a spring 19.

The head of the retaining pin 16 has a convex portion 20 that fits into the concave portion 10.
It becomes. When the concave portion lO and the convex portion 2o are engaged, the convex portion 20 is deeper than the center O of the engaging member 11 in the concave portion 10.
It will be inserted inside.

At the foot of the retaining pin 16, there is a rod 2 disposed inside the gripping rod 4.
One end of 2 is screwed. The other end of the rod 22 is a hook portion 22a bent in a U shape, and a lever 26 is rotatably attached to a groove-shaped notch 23 formed at the lower end of the grip lever 4 with a stop pin 24. The upper end portion of the hook portion 22a is engaged and connected to the hook portion 22a. Lever 2
6 is normally in a state of protruding downward from the lower end of the grip rod 4.

When the lever 26 is facing downward.

Since the convex portion 20 of the retaining pin is inserted into the concave portion 10 of the retaining member by the action of the spring 19, the fourth pivot member 7 and the second pivot member 8 are integrated, and are attached to the main rod 2. The grip rod 4 and the forearm support rod 5 are non-rotatable. When the lever 26 is pulled in the A direction, the engagement pin 16 moves in the B direction via the rod 22, and the convex part 20 comes out of the concave part lO, so that the first pivot member 7 and the second pivot member 8 are mutually attached. The grip rod 4 and the forearm support rod 5 can be rotated relative to the main rod 3 within the range of the walking state shown by the solid line in FIG. 3 and the seat state shown by the chain line in FIG. In the sitting state, the angle θ2 between the main rod 3 and the forearm support rod 5 is smaller than 90 degrees, preferably around 85 degrees.

A forearm fixture 30 is attached to the front side of the upper end of the forearm support rod 5 in an upright state. This forearm fixture 30 is
It is made of an elastic material such as Plasti-2, has a space 31 through which the forearm passes, and has an opening 32 formed in the front. In addition, the lower end of the main rod 3 has an anti-slip carrier,
A grip 33 is attached, and a grip 4 is covered with a grip 34. Furthermore, the main rod 3 and the forearm support rod 5 may be provided with a length adjustment mechanism.

When walking, the cane I is placed in the walking state shown in FIG. 1, the forearm is passed through the space 31 of the forearm support 30 from above, and the grip 34 of the gripping rod 4 is grasped with the hand. Since the forearm support rod 5 is fixed to the forearm, the cane does not wobble and the user can walk safely. In an emergency, the forearm can be removed from the forearm support 30 by pushing open the opening 33.

When sitting on a chair, bench, etc., the forearm support rod 5 is tilted backward while pulling the lever 26, so that the seat is in the sitting position as shown in FIG. The lever 26 can be easily pulled by hooking it with the index finger.

Since the forearm support rod 5 and the grip rod 4 are integrated, the grip rod 4 is in an upright state. For this reason, the seater can keep his/her grip on the grip rod 4 even at times, and the cane will not fall down or shift unexpectedly.Furthermore, when standing up from the chair, a downward and slightly diagonal backward force is applied to the cane 1. Easy to put in,
Stand-up operation is easy. In particular, in the seat position, the angle θ2 between the main rod 3 and the forearm support rod 5 changes from 80 degrees to 9 degrees.
If it is set between 0 degrees, preferably about 85 degrees, the direction of the main rod 3 will be almost the same as the direction in which force is applied, making the rising operation easier. Furthermore, if θ2 is smaller than 90 degrees, the lower end of the main rod 3 of the seat will sometimes be located rearward than the upper end, and will not obstruct the forward passage.

[Effects of the Invention] As is clear from the above description, the cane for physically disabled persons according to the present invention has the following advantages: The chair allows the user to take a comfortable posture at times, and it also makes it easier to put pressure on the cane when standing up from a chair or climbing stairs, making standing up and climbing movements safer and easier.
