Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cane.

[0002]

[Problems to be solved by conventional techniques and devices]

 Various types of canes used for assisting walking and movement of humans are known, such as crutches and other bifurcated ones, and sticks and other stick-shaped ones. In this specification, similar parts are collectively referred to as stone sticks.) And a main body part as a bifurcated or stick-shaped cane, and a crutch for supporting the body in addition to these. Arm support and rungs are provided on the cane side.

[0003] By the way, the stick of the cane is often a member having a shape in which the tip side, that is, the side protruding from the ground, is thinned. However, such a tapered shape increases the installation area on the ground that the ground contact state is not stabilized. Many things have been proposed.

[0004] That is, with a cane having a tapered stone foot, if the user puts his weight on the ground during walking, the user can easily slip due to the small installation area and easily fall. In other words, since the ground touches at a point, depending on how the ground is touched, the reaction force received at the time of landing may be transmitted to the wand without being buffered, causing an unpleasant impact on the user's hands, sides and shoulders. Prone.

[0005] On the other hand, a cane having a stiletto with an increased installation area can solve the above-described problems such as the tapered stiletto, but the angle between the lower surface of the stilt and the axis of the cane body is constant. Physically, there is a problem caused by the fact that it is fixed at a right angle. In other words, it is most stable to ground the bottom of the ram with the cane body straight on the ground, but this tends to be a very unnatural operation, and therefore, the cane body is inclined with respect to the ground. And lower the stone at an appropriate angle, gradually bringing the entire surface into contact with the edge of the lower surface of the ram. However, such a method of grounding was extremely unstable until the entire lower surface of the sill was grounded, and the edge of the lower surface of the sill was easily worn or damaged.

[0006] Furthermore, both a cane having a tapered tip and a cane having an enlarged footprint have the disadvantage that they easily slip and fall when leaning against a wall, chair, desk or the like. In other words, the former is slippery because the installation area is originally small. Also, the latter cannot be leaned straight, so it is inclined at an angle, and only the edge of the lower surface of the sill is grounded, so it is easy to slip and fall.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a cane that is hard to slip, has a small impact when touching the ground, and is hard to fall down when leaned up.

[0008]

[Means for Solving the Problems]

 The cane according to claim 1 of the present invention is a cane for supporting a body in order to achieve the above-mentioned object, wherein a sword is a flat-shaped grounding member, and the grounding member is moved upward from the center of the grounding member. A protruding shaft portion, and the upper end of the shank and the lower end of the cane body are swingably connected by a universal joint, and the shank portion of the hob and the lower end of the cane body. Surrounding the vicinity and the outer periphery of the universal joint with a coil spring capable of allowing the rocking shaft and the cane to swing, and positioning the coil spring on the outer periphery of the enclosed portion. It is characterized by.

According to a second aspect of the present invention, a non-slip rubber material is attached to a lower surface of the ground member of the ram.

[0010]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial sectional side view of an embodiment of the stick according to the present invention, and FIG. 2 is an enlarged partial sectional side view of a main part. The staff shown is a crutch, the upper ends of the bifurcated struts 1, 1 are connected by means of an arm 2, and a grip 3 is arranged in the middle of the struts 1, 1, and the struts 1, 1 The footpiece 4 is fixed to the lower end side, and a stone foot 7 is connected to the lower end of the footpiece 4 via a universal joint 5 and a coil spring 6. In the figure, 8 is a long screw for fixing the grip 3 between the columns 1 and 1, 9 is a thumb screw, 10 is a cap, and the cap 10 is placed on the lower end of the columns 1 and 1, and the center part is a footpiece. 4 penetrates. The footpiece 4 is a double tube, and the side to be attached to the column 1 is fixed, and the part protruding downward from the cap 10 is protruded and retracted from the side to be attached to the column 1. Thus, the height of the arm rest 2 can be changed according to the height and the like of the user. However, since such a structure for changing the height is well known, detailed illustration and description are omitted.

The shingle 7 is made of a flat plate material 11 such as a metal plate or the like having a certain degree of rigidity, a cushioning non-slip member 12 made of rubber or the like adhered to the lower surface thereof, and an upward direction from the center of the flat plate material 11. The shaft member 13 is formed so as to protrude. The flat plate 11 has an appropriate area larger than the cross-sectional area of the footpiece 4. It should be noted that various materials can be adopted as the material of the members forming the ram 7 and are not limited to the combination of the metal material and the rubber material of the present embodiment.

A feature of the walking stick according to the present embodiment is that a stone peg 7 is connected to a lower end of the footpiece 4 via a universal joint 5 and a coil spring 6. The universal joint 5 connects the lower end of the footpiece 4 and the upper end of the shaft member 13 of the ram 7 in a swingable manner. In the illustrated example, a simple hook type is used, but of course, the present invention is not limited to this, and various types can be used. The coil spring 6 is a compression spring having a diameter larger than that of the lower end of the footpiece 4 and the shaft member 13 of the butt 7, and a stop pin provided near the upper surface of the flat plate 11 of the butt 7 and the lower end of the footpiece 4. 14 and surrounds the lower end of the footpiece 4, the upper end of the shaft member 13 of the ram 7, and the outer periphery of the universal joint 5. The coil spring 6 can be bent in accordance with the swinging rotation of the foot piece 4 or the shingle 7, and in the bent state, the foot piece 4 and the shaft member 13 of the shingle 7 are aligned in a straight line. Energize to return.

A use state of the walking stick according to the present embodiment will be described. When the non-slip member 12 of the ram 7 is not grounded, the foot piece 4 and the shaft member 13 of the ram 7 are aligned in a straight line by the urging force of the coil spring 6 as shown in FIG. From this state, when the edge of the non-slip member 12 of the shingle 7 lands in a state in which the support 1 is slanted by swinging forward (to the left in FIG. 3), the force applied from the support 1 is not perpendicular to the ground contact surface. Also, by the action of the universal joint 5, the shingle 7 quickly pivots downward, and the whole of the non-slip member 12 comes into contact with the ground, thereby creating a stable landing state as shown in FIG. In this landing state, the upper portion of the coil spring 6 bends in response to the swinging rotation of the footpiece 4 (or the shingle 7), and returns to a state in which the footpiece 4 and the shaft member 13 of the shingle 7 are aligned. Energize to do. When the user moves forward from this state by walking or the like, the portion above the footpiece 4 swings forward around the connecting portion of the universal joint 5, and the bending state of the coil spring 6 is also interlocked with this. However, due to the presence of the universal joint 5, the non-slip member 12 of the ram 7 keeps a stable state in which the whole surface is grounded.

As shown in FIG. 4 which is a partial cross-sectional front view showing another use state of the present embodiment, the cane according to the present embodiment is configured such that the portion above the footpiece 4 is also laterally moved by the universal joint 5. It can swing and rotate, and can maintain a stable ground contact state. Therefore, when leaning the cane on a desk or the like, as shown in FIG. 5, the cane is tilted in the same manner as shown in FIGS. Leaning against 5 mag will keep you stable without falling down unless external force is applied.

In addition, in general, in this type of cane, the lower component is made heavy to lower the center of gravity, thereby trying to create stability. In addition to this, the properties such as the urging force of the coil spring 6 and the flexibility. By appropriately selecting, the non-slip member 12 of the stone foot 7 can be made to be self-supporting in a state of being entirely grounded on a flat surface.

FIG. 6 is a partial sectional side view of another embodiment of the cane according to the present invention, and FIGS. 7 and 8 are partial sectional side views and partial sectional front views corresponding to FIGS. The wand of this embodiment is a so-called walking stick, one thin rod-shaped wand part 20, a grip 21 at the upper end thereof, and a shingle 7 having the same configuration as that of the previous embodiment. And a coil spring 6. Since the configuration and operation are almost the same as those of the previous embodiment, the description is omitted.

[0017]

[Effect of the invention]

 As described above, the cane according to the present invention is configured such that the upper end of the sword end having a flat grounding member and the lower end of the cane body are swingably connected by a universal joint, and the stub end of the stake end Around the lower end of the cane body and the outer periphery of the universal joint with a coil spring, and are positioned on the outer periphery of the surrounding part to allow the rocking shaft and the cane body to swing. As a result, the ground contact member of the stilt quickly grounds to the ground or the floor surface in the same way as the sword of the tapered cane, and the large installation area stabilizes the grounding condition, making it very easy for the elderly and injured to use. This has the effect. In addition, there is also an effect that the entire surface of the grounding member can be leaned against a wall, a desk, or the like in a very stable state with the whole surface being grounded.

In the wand according to the second aspect, since the anti-slip rubber material is attached to the lower surface of the ground member of the stone foot, in addition to the above-mentioned common effect, a more reliable landing state can be realized. It has the effect of enabling very high stability when leaned.
