Description

  The present invention relates to a cane diversion technique.

  Conventionally, there have been crutches and canes as separate tools, but none have been combined.

Therefore, there are the following problems.
(I) The condition of the foot worsens with age, such as the elderly, and the necessary equipment changes from the cane to crutches and wheelchairs. Similarly, injuries such as broken bones will turn into wheelchairs, crutches and canes as they recover. In this way, a cane and a crutch were prepared separately according to the degree and progress of injury. All these items were wasted in cost and storage location.
(B) There is a problem in convenience to perform other actions using the hand while using a tool such as a cane, and there is no useful strap even if it is diverted to either a cane or a crutch to solve this It was.
The present invention has been made to solve these problems.

  In order to solve the above-mentioned problem (a), the support column is composed of two cylinders having different diameters or one round bar and a cylinder having a diameter larger than that of the round bar. A telescopic cane having a mechanism for inserting a round bar and sliding and locking both, and having a grip portion having a mechanism for similarly sliding and locking the outside of the inner cylinder or the round bar, and A cane characterized in that a side pad provided with a locking mechanism that can be easily detached from the support column is provided at the upper end of the inner cylinder or round bar, and can be easily diverted to any use of crutches or canes. It is. In addition, in order to solve the above-mentioned problem (b), it is possible to secure and adjust the length of the cane so that it can be hung on the opposite shoulder of the hand holding the cane and does not interfere with walking using the cane. A cane comprising a strap provided at both ends of a hook that can be attached to and detached from a retaining ring, and a retaining ring for locking a hook of a shoulder strap at both front and rear ends of a side pad and an end of a gripping part. It is.

  By using the tool of the present invention, it is not necessary to prepare a cane or a crutch separately according to the degree or progress of injury or illness. By adjusting the length, it can be diverted from cane to crutch or from crutch to cane. In addition, the shoulder straps can be easily attached to and removed from the armrests and grips in response to diversion, and the user's hands and wrists can be freely released without removing the tools from the user's body, thereby expanding the range of daily activities. Can do.

Embodiments of the present invention will be described below.
(A) The support column is composed of two cylinders (2) (3) having different diameters or one round bar (1) and an outer cylinder (2) having a diameter larger than that of the round bar. ) Is inserted into the inner cylinder (3) or the round bar (1) having a small diameter, and the telescopic cane having a mechanism for sliding and locking both of the inner cylinder (3) or the round bar (1) Similarly, there is a gripping part (4) having a mechanism for sliding and locking, and a side pad part (5) having a locking mechanism at the upper end of the inner cylinder (3) or the round bar (1). Each of the armrest part (5) and the grip part (4) has a mechanism that can be detached from the support column.
(B) The outer peripheral surface of the round bar (1) or the inner cylinder (3) has a locking hole row (6) parallel to the longitudinal direction. Further, a pin that is inserted into and locked by the force of the springs (9) and (10) into the locking holes of the locking hole row (6) as locking mechanisms on the side pad (5) and grip part (4). (7) Lever (11) (12) which cancels locking by pulling back (8) and spring (9) (10) is provided. Therefore, the latching pin (7) of the side pad portion (5) is inserted into the locking hole (6a) at the upper end of the round bar (1) or the inner cylinder (3). Made possible by. Similarly, the locking pin (8) of the grip portion (4) can be arbitrarily selected by the user in the locking hole (6b) of either the round bar (1) or the locking hole row (6) of the inner cylinder (3). Select and lock.
(C) The round pin (1) or the inner cylinder (3) and the outer cylinder (2) are arranged so that the locking pin (13) attached to the column locking ring (15) is a locking hole of the outer cylinder (2). (14) penetrates and is locked by being inserted into an arbitrary locking hole (6c) of the round bar (1) or the inner cylinder (3). The strut locking ring (15) is divided into two hinges so that it can be easily detached from the strut. The wings are pivoted on one axis (26), and the other wings are snap-type fasteners (16) and fastener catches (16a). Is provided.
(D) When the armpit part (5) is removed, the exposed upper end of the column is covered with a removable cap (17) in consideration of safety and appearance.
For mounting the cap (17), a screw (27) embedded in the cap is provided with a female screw (29) provided on the upper end surface of the round bar (1) or a round plate provided inside the upper end of the inner cylinder (3). It is mounted by screwing into the female screw (29) of (28).
(E) Since the armrest part (5) can be removed, the upper arm support (18) having a locking mechanism equivalent to the grip part (4) can be mounted.
(F) A retaining ring (19) is provided at both the front and rear ends of the side pad portion (5) and the grip portion (4). A strap (21) provided with detachable hooks (20) from both ends of the retaining ring (19) is attached. Even if the strap (21) is hung on the shoulder on the opposite side of the hand holding the cane, the strap (21) can be secured and adjusted to a sufficient length so as not to interfere with walking using the cane.
