Abstract

PROBLEM TO BE SOLVED: To make a stick act in the vertical direction even if the main body is used angled against a road face to prevent inconvenience such as sliding, etc., by fixing a slip-proof body to the lower end of the main body via a universal joint. SOLUTION: A rod main body of this stick is equipped with a handle and a slip-proof body is fixed on the lower end of the main body. The slip-proof body has a universal joint 4 on the upper end and a slip-proof part 6 with a suction mechanism 5 such as a dent part on the lower face, i.e., the face to be in touch with the ground face. A support axis 7 is fixed to a ball 8 of the universal joint 4, the ball 8 is stored in a storage part 9, and the upper face periphery is locked in a cut-off spherical arc part 10. Further, the universal joint 4 has a cylinder part 12 which is connected with the cut-off spherical arc part 10 and adjustably engaged by friction force with a storage periphery wall part 11 by pushing operation. The storage part 9 is equipped on the top of the slip-proof body and the support axis 7 is inserted and fixed to the tip end of the stick main body.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
It relates to a cane suitable for the disabled.

[0002]

2. Description of the Related Art Various types of canes of this type are known. In each case, a non-slip body made of rubber or the like is fixed to the lower end of the cane body so that the lower end of the cane body can be used when used. Is prevented from slipping on the road surface to ensure safe use.

[0003]

However, in such a cane with a non-slip body, the intended purpose can be achieved by always using the cane body so as to be perpendicular to the road surface.
During normal walking, it is difficult to maintain a vertical state when using the road diagonally or on slopes and stairs, and it is often used diagonally. However, there is an inconvenience that sliding often does not provide a sufficient anti-slip effect. In short, there is a problem that a highly safe anti-slip effect cannot be expected even if the anti-slip function is provided.

The present invention has been made by paying attention to the points described above. Even when the cane body is used obliquely, it always acts on the road surface in the vertical direction and does not cause any trouble such as slipping. To provide a safe cane for excellent use.

[0005]

The present invention can solve the above-mentioned problems by providing the following constitution.

(1) A cane characterized in that a non-slip body is fixed to a lower end of a cane body via a universal joint.

(2) The universal joint has a ball provided with a support shaft, a storage portion for storing the ball, a cutout spherical arc surface portion capable of holding the periphery of the upper surface of the ball, and a continuous notch spherical arc surface portion; The storage portion peripheral wall and a tubular portion that can be locked in an adjustable manner, the spindle is fixed to the lower end of the cane main body, and the storage portion is provided on the top of a disc-shaped elastic non-slip body having a non-slip function. The wand according to the above (1), which is provided.

(3) The cane according to the above (2), wherein a hard plate is interposed at a place where the ball comes into contact with the storage portion for storing the ball.

[0009]

Embodiments of the present invention will be described with reference to the drawings.

In each of the drawings, reference numeral 1 denotes a stick-shaped wand body provided with a handle 2, and 3 denotes a non-slip body fixed to a lower end of the wand body 1. The non-slip body 3 has a universal joint 4 at an upper portion, and a non-slip portion 6 having a suction mechanism 5 such as a concave portion formed on a lower surface, that is, a surface in contact with the ground surface.

The universal joint 4 includes a ball 8 to which a support shaft 7 is fixed, a storage portion 9 for storing the ball 8, and a notched spherical arc surface portion 10 capable of holding the periphery of the upper surface of the ball 8.
And a cylindrical portion 12 which is connected to the notched spherical arc surface portion 10 and which can be adjusted and locked by frictional force by a pushing operation with the storage portion peripheral wall 11. The support shaft 7 is fitted and fixed to the tip of the cane main body 1.

The anti-slip body 3 is made of a hard rubber material and can be obtained as a disk-shaped elastic structure.

Further, a hard plate 13 made of hard plastic or the like, which can abut against the lower surface of the ball 8 and can hold the ball 8 without loosening, can be provided in the receiving portion 9 in the receiving case 14.

The distance L between the lower end 12a of the cylindrical portion 12 connected to the notched spherical arc surface portion 10 supporting the ball 8 and the opening end of the storage portion 9 is sufficiently long to support the ball 8 It is preferable that the height M of the hard plate 13 in the container 14 be sufficiently large so that the lower end 12a of the cylindrical portion 12 can be pushed in as necessary.

Since the above-described configuration is used, even if the gripped cane body 1 is inclined, the non-slip body 3 at the tip can be
As shown in FIGS. 5A and 5B, the universal joint 4 always acts vertically on the road surface in any state irrespective of the inclination or fluctuation of the cane main body 1, and the entire lower surface of the non-slip body 3. As a result, the stick can be kept in contact with the road surface without shifting, so that the effect of the cane can be exhibited safely and securely without taking an unstable state.

Further, in this embodiment, when the ball 8 provided with the support shaft 7 is loosened in the storage portion 9 when the pressing of the notched spherical arc surface portion 10 is loosened and the connection state with the non-slip body 3 is loosened, the notch is formed. Lightly pressing the spherical arc surface portion 10 to move the lower end 12a of the cylindrical portion 12 of the cutout spherical arc surface portion 10 downward in the peripheral wall 11 of the storage portion 9 and lock it to eliminate looseness and return to the current state Can be.

Therefore, even in the case of long-term use, the universal joint 4 can be used while maintaining an appropriate connected state without loosening.

In the above embodiment, the receiving case 14 and the hard plate 13
And a ball receiver 13a having one concave arc surface
FIG. 6 shows an embodiment provided with. In this case, the same operation as in the above-described embodiment is exhibited.

As another embodiment of the present invention, a universal joint 4a shown in FIG. 7 can be used.

In this embodiment, a ball 8 provided with a support shaft 7 is held by a cylindrical portion having a cutout spherical arc surface portion 10 for holding the ball 8 and a flange 15 connected to the cut surface. A hard non-slip body 17 made of rubber or the like and the flange 15 are brought into contact with each other and fixed integrally with a tightening tool 18 such as a bolt and a nut. The looseness of the ball 8 can be reduced by interposing the resilient body 19.

The universal joint 4a in this case also exhibits the same operation as that of the above-described embodiment, and can provide a highly safe wand having a reliable anti-slip effect.

Although two examples including the universal joint have been described above, any structure having a universal joint having a ball or the like can be easily implemented.

[0023]

According to the present invention, since the universal joint is used, the anti-slip body always abuts perpendicularly to the road surface and can be reliably supported over the entire lower surface, no matter how the inclined cane is used. Therefore, there is no inconvenience such as inadvertent slipping or incomplete contact, etc., it can always exert a safe and reliable cane function, and it is suitable for the elderly, disabled people with walking difficulties and rehabilitation, and the ball of the universal joint is It is very convenient because the loosening of the ball can be easily adjusted by pressing the notched spherical arc surface portion provided in the storage portion of the non-slip body made of a hard elastic material and always holding the ball.
