Description

  The present invention relates to a cane that supports a load of the body and assists walking, and more particularly to an improvement of a cane that can stand on its own.

  As is well known, walking sticks are used by the elderly and the disabled. And this cane is generally a simple shape with a grip on the upper part of the rod-shaped cane main body and the lower end is a grounding part, so when the user releases his hand from the cane The cane falls to the ground, road surface, or floor surface. In other words, the shape is not self-supporting. Therefore, in such a case, it is difficult for the user to raise and pick up the cane. Also, when spending time sitting in a chair in a waiting room or the like, the cane cannot stand on its own, and often leans diagonally.

Therefore, a device for a cane that can stand on its own has been proposed.
No. 1 is provided with a stand means that enables a switching operation between a laterally projecting posture and a storage posture along the main body frame at the distal end of the elongated main body frame, and the stand means projects laterally. This is a cane that supports the main body frame in an upright state when it is in a posture, and stores a stand in the slit of the main body frame when using the cane. (Patent Document 1)
No. 2 is a cane having a handle at the upper end of the cane shaft and a grounding part at the lower end, and has three or more rectangular slits in the axial direction on the lower side surface of the hollow cane shaft, and a movable part and a fixed part in the slit. Provided so that the end of the auxiliary leg can be rotated to the movable part and the intermediate part of the auxiliary leg can be rotated to the fixed part via the connecting member, and between the movable part and the fixed part, the coil spring, the movable part and the cane There has also been proposed a self-supporting cane configured by attaching a wire between a locking portion provided on an upper portion of the shaft. (Patent Document 2)
The third is that the grounding part is connected to the base of the cane body via a flexible joint such as an anti-vibration rubber, and the grounding part has such a size that the cane body can be held in a vertical state. There has also been proposed a cane whose relative angle can be changed by the flexible joint. (Patent Document 3)
FIG. 4 is a diagram for explaining this prior art. In FIG. 4, A is a cane body, B is a part having a grounding portion, C is a flexible joint such as a vibration-proof rubber, and D and E are each a cane body. A screw for connecting the flexible joint C to A, and E a screw for connecting the grounding portion B and the flexible joint C to each other.

Although these conventional technologies can stand the wand even if the hand is released from the cane, in the case of the conventional technologies 1 and 2 above, the stand or the auxiliary leg is configured to be able to go in and out of the slit, so the number of parts is large. Because there are many assembly steps, or there are many failure factors because it moves by opening and closing, there is room for improvement in these points, especially when walking with a cane, the cane body can be moved freely with respect to the stand or auxiliary leg Since it cannot be used, the stand or auxiliary leg cannot be used with the stand extended, and the stand or auxiliary leg had to be accommodated in the slit. In other words, it took time and effort to open and close the stand or auxiliary leg when walking with the cane and when walking with the cane.
In addition, since the slit is formed in the cane body, the strength of the cane, which takes a lot of weight, is weakened and there is a difficulty in safety.

In this respect, the third prior art allows the cane to stand on its own and allows the cane body A to move freely with respect to the grounding part B as it is. Therefore, when walking with the cane, the cane body A is slanted according to the walking step. It has the advantage of being easy to use. However, the tip of the wand body A is not grounded, and only a flexible joint C such as a vibration-proof rubber is interposed between the grounded portion B and the grounded portion B. It is dangerous to buckle. That is, the flexible joint C is inherently flexible because its function is to move the cane body A freely.
For this reason, the original function and safety of the cane such as the flexible joint C buckling when the load greater than the setting is applied or the load is applied in the wrong direction, and the cane body bends at the flexible joint C. May be disturbed.

  The present invention has been made in view of the above points. The object of the present invention is to provide a cane that can stand on its own even if the hand is released from the cane, and has few movable parts and parts. To provide a cane that can be self-supported with few points and assembly man-hours and with few failure factors. Especially when walking with a cane, it can be freely moved according to the walking step of the person without opening or closing anything. In addition to providing an easy-to-use cane that can move the body diagonally with respect to the grounding leg, the cane body is less likely to bend depending on how the weight is hung, and can stand on its own. To provide a cane.

  In order to achieve the above object, the present invention has the following means. That is, using the reference numerals in the examples shown in the best mode for carrying out the invention, the invention of claim 1 is provided with a grip portion 3 on the upper portion of the cane body portion 2 and a tip portion. 4 is provided with a grounding leg 5 so that the cane body 2 can be tilted while the grounding leg 5 is grounded. The grounding leg 5 is grounded to the lower part of the body 6. An end surface 8 is formed and a through hole 7 is formed in the top surface 10. The cane body portion 2 is tilted through the through hole 7 and the tip portion 4 is ungrounded. In this manner, the grounding leg 5 is always urged by the spring 13 held by the spring receiver 14 attached to the distal end portion 4 in a non-grounding manner, and the stopper 11 whose top surface 10 is always provided on the cane body 2. To hold it against Is a self-sustainable cane to butterflies.

  According to the second aspect of the present invention, the grip portion 3 is provided on the upper portion of the cane body portion 2 and the ground leg 5 is provided on the tip portion 4, and the cane body portion 2 is tilted while the ground leg 5 is grounded. In the cane that can stand by itself, the grounding leg 5 has a grounding end surface 8 formed in the lower part of the main body 6 and a through hole 7 formed in the top surface 10. The cane body 2 is tilted through the hole 7 so that the tip 4 can be ungrounded, and the receiver 14 is attached to the cane body 2 from the back surface 16 side of the grounding leg 5 in an ungrounded manner. A spring 13 is mounted between the stopper 11 provided on the cane body 2 and the top surface 10 of the grounding leg 5 in such a state that the grounding leg 5 is attached to the grounding leg 5 in a tiltable manner. This is a self-supporting cane characterized in that it is pressed against and held.

According to the first and second aspects of the present invention, when the hand is released from the cane 1, the cane body 2 is independent by the grounding leg 5. It is held vertically by a spring 13. Therefore, the cane does not fall on the ground.
When walking with the cane 1, if the cane body 2 is tilted with the grip 3, the cane body 2 can be freely tilted with respect to the ground leg 5, and the spring 13 returns to the vertical position. Since the force is given, the cane body part 2 cannot fall carelessly even if the external force is released. Accordingly, when the grounding leg 5 is grounded and walking forward, the cane is tilted to start the next operation, but the walking step is easy to take.
In particular, the cane body 2 is supported by the grounding leg 5 with the stopper 11 interposed therebetween, that is, the cane body 2 is held by the rigid grounding leg 5. Since it is not only done, the cane body part 2 will not be bent inadvertently regardless of how the load is applied. Therefore, it is safe.

Next, a first embodiment of the present invention will be described in detail with reference to FIGS.
In the figure, reference numeral 1 denotes a cane, and a grip portion 3 is formed on the upper portion of the rod-shaped cane body portion 2, and a grounding leg 5 is provided on the lower portion.
The cane body 2 is shown as a single unit in this embodiment, but two or more cane bodies may be connected to be stretchable.

Now, the grounding leg 5 has a main body 6 having a cup-like shape, and the lower part thereof is formed as a grounding end face 8 with a flat and flange-like shape projecting outward.
In this example, an anti-slip rubber 9 is attached.
A through hole 7 is formed in the center of the top surface 10 of the cup-shaped main body 6, and the tip 4 of the cane main body 2 is passed therethrough. That is, the diameter of the through hole 7 is set to be slightly larger than the outer diameter of the distal end portion 4 of the cane body 2 so that the cane body 2 can be freely tilted with respect to the grounding leg 5.

And the attachment of the grounding leg 5 and the cane main body 2 is made as follows.
First, the cane body portion 2 passed through the through hole 7 of the grounding leg 5 is inserted until the stopper 11 attached to the cane body portion 2 comes into contact with the top surface 10 of the grounding leg 5. In this state, the spring 13 is mounted around the cane body 2 from the distal end 4 side. A spring receiver 14 is attached to the distal end portion 4, and the spring 13 is interposed between the receiving surface 17 of the spring receiver 14 and the back surface 16 of the top surface 10 of the grounding leg 5. The spring 13 keeps the cane body 2 vertical even when the top surface 10 of the grounding leg 5 is pressed against the stopper 11.

  Both the stopper 11 and the spring receiver 14 are firmly coupled to the cane body 2 by the caulking portions 12 and 15 without loosening.

Thus, the spring receiver 14 is attached to the distal end portion 4 of the cane body portion 2 with a slight gap S with respect to the road surface so that the bottom surface 18 is not grounded.
Reference symbol S indicates a gap between the bottom surface 18 and the ground contact end surface 8 (anti-slip rubber 9).

According to the above, even if a person releases the hand from the cane 1, the cane 1 is self-supporting as shown in FIG. That is, since the spring 13 presses the top surface 10 of the grounding leg 5 against the stopper 11, the stopper 11 maintains an upright posture as shown in FIG. Of course, since the spring receiver 14 also maintains the upright posture as shown in FIG. 1 by the spring 13, the cane body 2 is held in a vertical posture. As a result, the cane is self-supported by the ground leg 5.
Therefore, even if the hand is released from the cane, the cane does not fall on the road surface or the like. This makes it possible for the wand to stand on its knees when sitting on a chair in a waiting room or the like and not causing injury to other people.

In order to make this self-supporting possible, the stand or the like does not open and close unlike the prior art, so there is no part that moves greatly, so the failure factor is small and durable.
Particularly, since the grounding leg 5 is formed in a cup shape, the rigidity is high. And since it is cup-shaped, the flat grounding end surface 8 looks like a circular ring, has a large grounding area compared to a frame-like stand or the like, and has good stability when grounded.

In particular, when walking with a cane, the grounding leg 5 remains in contact with the ground in an oblique manner toward the walking direction, starting with the cane (as shown by the solid line from the dotted line in FIG. 2), and then walking. It can move freely and diagonally forward (as shown by the dashed line in FIG. 2) toward the walking direction. This is because the cane body 2 is attached to the ground leg 5 so as to freely tilt.
Therefore, it is easy to walk.
Since the spring 13 tries to hold the cane body 2 in a vertical posture, when the cane is tilted, it does not incline unexpectedly, and it tilts according to the movement of the hand and releases the load on the cane. Returns to its original vertical position without falling down. Therefore, it is easy to handle and safe.

  In the above case, the cane body 2 is not held only by the spring 13. Basically, the cane body 2 is supported by a rigid cup-shaped ground leg 5. Therefore, even if the load applied to the cane is mistaken or a large load is applied to the cane, the cane body 2 is not buckled or bent.

Next, the second embodiment of FIG. 3 will be described in detail. In this embodiment, the spring receiver 14 is simply the receiver 14, and the spring 13 is interposed between the stopper 11 and the top surface 10 of the cup-shaped ground leg 5, and the back surface 16 of the ground leg 5 is secured by the spring 13. It is configured to always press against the receiving surface 17 of the receiver 14, and the other parts are the same as those in the first embodiment.
Also in this embodiment, the cane can stand on its own, and the cane body 2 can be tilted with respect to the ground leg 5 during walking.
The cane body 2 is held on the rigid grounding leg 5 sitting on the receiver 14 and is not held only by the spring. They do not buckle or bend.

  In both the above-described Examples 1 and 2, slits are not formed in the existing cane, or a flexible joint is attached by cutting in the middle, but the stopper 11 is passed from the tip 4 in the state of the existing cane, Since it can be made as a cane that can stand on its own by simply caulking and passing the grounding leg 5 and the spring 13 from the tip part 4 and the spring receiver 14 on the tip part 4, there is an advantage that it can be easily applied to existing canes.
