Description

  The present invention relates to a cane, and more particularly to a cane for a person with a disability in a foot to walk under an armpit.

  The armrest that supports the side of the user who has a foot disorder is provided at the top, and the gripping part for the user to grip is provided midway. The armpit is placed under the armpit of the user and the weight is supported by the cane. In addition, a cane for supporting walking by holding a gripping part and swinging the cane around the side pad part as an axis is known as a so-called crutch.

And as said crutch, a cane body is composed of two members before and after converging downward, and a side pad portion is provided at the upper end of the two members, and it is bridged over them in the middle of the member. A double type with a gripping part (Patent Document 1) and a single type with a side support part at the upper end of one cane body and a gripping part protruding in the middle of the cane body (patent Documents 2 and 3) are known.
JP-A-62-127052 Microfilm of Japanese Utility Model No. 57-127847 (Japanese Utility Model Publication No. 59-33416) Microfilm of Japanese Utility Model No. 46-12712 (Japanese Utility Model Publication No. 47-11595)

  In the above-mentioned prior art cane, the double-type cane has a tip of the cane body positioned just under the side pad portion, which is in contact with the ground. Moreover, the thing of patent document 2 by which the side pad part of the upper end of the cane body protruded toward the back among 1 type | formulas has the front-end | tip of a cane body located just under the front part of a side pad part, Similarly, in the case of the device described in Patent Document 3 in which the side pad portion at the upper end of the cane body protrudes forward and backward, the tip end of the cane body is positioned directly below the arm pad portion, and this is in contact with the ground.

  The inventor of the present invention examined the above-mentioned conventional cane, and when the user tries to walk forward relying on the cane, the user tries to move the weight forward using the cane. Since the load of the previous user is applied directly under the side, if the tip of the cane is located directly under or in front of the side in the same direction as the load, it is located at the same position or behind the position where the load is applied. I found out that it meant to do and was not suitable for the current situation.

  In addition, when the tip of the cane is positioned directly below or in front of the side, the tip of the cane that has been swung out, for example, when there is a step or an obstacle on the road, first collides with them. I also discovered that there was a phenomenon that had to be shrunk.

  This device was created in view of the above-described current state of the cane, and in a cane having a side pad portion for supporting the user's side and a grip portion for the user to grip, The armrest and gripping part protrude from the inner periphery of the rod-shaped cane body that is curved in an arc, and the lower end of the cane body is curved so that it is located behind the vertical line descending from the armpit part. Characterized by setting the degree

  In addition, here, in a cane having a side abutting part for supporting the user's side and a gripping part for the user to hold, the arm is placed on the inner peripheral side of a rod-shaped cane body curved in an arc shape toward the rear. Abutment and gripping part project, and the degree of curvature is set so that the lower end of the cane body is located behind the vertical line descending from the above-mentioned side rest part, and further swings up and down with respect to the cane body A second device is also disclosed as a cane characterized in that a means for pivotally supporting one end of the side pad portion on the cane body and fixing at a predetermined angle is provided.

  Further, in a cane having a side support part for supporting the user's side and a grip part for the user to hold, a side support part on the inner peripheral side of a rod-like cane body curved in an arc shape toward the rear, The gripping part is projected, and the degree of curvature is set so that the lower end of the cane body is located behind the vertical line descending from the side pad part, and the cane body can be swung up and down with respect to the cane body. As described above, one end of the side pad part is pivotally supported on the cane body, and the movement of the side pad part is regulated by an urging force so that the side pad part stops at one point of the swing locus below a predetermined load. A cane is also disclosed as the third device.

  Further, in a cane having a side support part for supporting the user's side and a grip part for the user to hold, a side support part on the inner peripheral side of a rod-like cane body curved in an arc shape toward the rear, The gripping part is projected, and the degree of curvature is set so that the lower end of the cane body is located behind the vertical line descending from the side pad part, and the cane body can be swung up and down with respect to the cane body. In this way, one end of the side pad part is pivotally supported on the cane body, and the movement of the side pad part is regulated by an urging force so that the side pad part stops at one point of the swing path below a predetermined load. Also disclosed as the fourth device is a cane characterized in that the angle at which one point exists can be set to a desired angle in advance.

  According to the cane of the present invention having the above-described configuration, as shown in FIG. 7, the cane body 1 is bent as an arc toward the rear, and the vertical line S where the lower end of the cane body descends from the side pad portion 3. Since the degree of curvature is set so as to be located further rearward, the user's load applied to the contact point P1 directly below the side, that is, the perpendicular S to the ground G is applied to the ground G at the tip of the cane body. It will be located in front of the contact point P, and it will be easy for the user to move in front of the body weight, making it easy to walk with a cane. Furthermore, in this case, since the cane body is curved, the elastic deformation caused by the bending reduces the impact given to the user when the cane body suddenly lands on the ground, or hard ground such as concrete. It can also be expected to reduce the impact from the walking stick when walking.

  Further, as shown in FIG. 6, the lower end of the cane body 1 of the present invention is in contact with the rear side of the cane according to the present invention, as compared with the conventional cane in which the lower end of the cane body T is in contact with the ground G directly under the user. Therefore, the reach distance A1 of the tip of the cane body when the cane body 1 descends forward with the side center X as an axis for walking is shorter than B1 of the cane body T of the prior art. Even if there is an obstacle, there is an effect that it is not necessary to shorten the stride like a conventional cane.

  In addition, as shown in FIG. 6, the height A2 of the tip of the cane body with respect to the ground G when the cane body 1 is lowered forward is B2 of the cane body T of the prior art when the same angle is swung out. Compared to the above, the difference in ground height between the start and end of swinging is small, and a stable landing of the cane is obtained.

  Next, in the case of the second device in which one end of the side pad portion 3 is pivotally supported on the cane body and can be fixed at a predetermined angle so as to be swingable in the vertical direction with respect to the cane body 1, FIG. For example, when the angle α1 between the side pad portion and the cane body (state (A)) is changed to an angle α2 larger than this (state (B)), The position P at which the tip abuts against the ground G is closer to the perpendicular S descending from the side pad part, and is farther in the opposite case. Therefore, according to this device, the position of the user's load with respect to the cane body can be adjusted by changing the angle of the side pad 3 with respect to the cane body 1, and thus it is possible to obtain a cane having the optimum comfort for the user. The effect which becomes.

  Next, one end of the abutting part is pivotally supported on the cane body so that it can swing vertically with respect to the cane body, and the abutting part stops at one point of the swinging locus under a predetermined load. In the case of the third device, in which the movement of the side pad portion is regulated by the urging force, the impact given to the user when there is a sudden landing on the ground of the cane body can be mitigated, and the hard ground such as concrete It is also possible to alleviate the impact from the cane body at the time of walking, and it is possible to obtain a cane with less burden on the user.

  As described above, according to the present invention, a cane that is easy to walk and has a low burden on the user is realized, and a cane that is easy to use is realized in combination with a single cane body and light weight. It becomes.

  Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. 1 to 7 are views showing an embodiment of the fourth device.
