[Solution] The tip of the walking stick has a main body portion 20 that is attached to the lower end of the walking stick and a cup-shaped portion 30 that has a cup shape. The main body portion and the cup-shaped portion are integrally formed, and the cup-shaped portion has a bulge portion 35 that is configured to protrude downward inside.

Description

Technical Field

[0001] The present invention relates to a cane tip for a cane used by patients with injuries or disorders in the lower body such as the feet, or the elderly with reduced walking ability, particularly a cane tip attached to the tip of a pine cone cane or a telescopic cane.

Background Art

[0002] Conventionally, when a patient with a disorder in the lower body moves, it is common to place the body weight on a cane and walk while adjusting the balance. However, since conventional canes are made of rigid materials such as wood like oak, aluminum alloy, and hard synthetic resin, the impact at the time of grounding is large, and vibrations are transmitted to the user's hands, arms, sides, and even the head, causing pain and injuries.

[0003] In order to solve these problems, Japanese Utility Model Laid-Open No. 1-87732 discloses a device that stabilizes the grounding surface and alleviates the impact by making the stone tip swing freely via a ball joint.

[0004] However, in these conventional stone tips, particularly in the type having a cup-shaped recess on the bottom surface, the space in the recess may be extremely compressed by the load at the time of grounding, and a negative pressure may occur inside. Due to this negative pressure, a so-called adsorption phenomenon occurs where the stone tip is adsorbed to the ground like a suction cup, and resistance occurs when separating the cane from the ground, so there is a risk that the user may lose their balance and fall.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The present invention has been made paying attention to the above points, and the problem is to provide a cane tip that can reduce the so-called adsorption phenomenon. [Means for solving the problem]

[0007] To solve the aforementioned problems, the first aspect of the cane tip comprises a main body portion attached to the lower end of the cane and a cup-shaped portion, the main body portion and the cup-shaped portion being integrally constructed, and the cup-shaped portion having a bulge portion that protrudes downward inside.

[0008] To solve the aforementioned problems, the second aspect of the cane tip comprises a main body portion attached to the lower end of the cane and a cup-shaped portion, the main body portion and the cup-shaped portion being integrally constructed, the cup-shaped portion having a bulge portion configured to protrude downward inside, the inside of the cup-shaped portion being a recessed space formed by the bulge portion, and the bulge portion restricts the change in volume within the recessed space when the cup-shaped portion makes contact with the ground and the recessed space is compressed.

[0009] To solve the aforementioned problems, the third aspect of the cane tip comprises a main body portion attached to the lower end of the cane and a cup-shaped portion, the main body portion and the cup-shaped portion being integrally constructed, the cup-shaped portion having a bulge portion configured to protrude downward inside, the inside of the cup-shaped portion forming a recessed space which is an empty space due to the bulge portion, the bulge portion which limits the volume change in the recessed space when the cup-shaped portion makes contact with the ground and the recessed space is compressed, and can also suppress the generation of negative pressure in the recessed space by contacting the ground. [Effects of the Invention]

[0010] As the present invention is configured and operates as described above, it is possible to provide a walking stick tip that can reduce the so-called adsorption phenomenon. [Brief explanation of the drawing]

[0011] [Figure 1] This is a front view of the tip of the walking stick in this embodiment. [Figure 2]This is a plan view of the cane tip of this embodiment. [Figure 3] This is a bottom view of the cane tip of this embodiment. [Figure 4] This is a perspective view of the cane tip of this embodiment. [Figure 5] This is a cross-sectional view along line AA in Figure 1. [Modes for carrying out the invention]

[0012] The cane tip 10 of this embodiment will now be described in detail with reference to the drawings. As shown in the drawings, the cane tip 10 of this embodiment comprises a main body portion 20 attached to the lower end of a cane (not shown) and a cup-shaped portion 30. The cane tip 10 of this embodiment also has a bulging portion 35, which will be described later. The cane tip 10, having the main body portion 20 and the cup-shaped portion 30, is integrally molded from an elastic material such as rubber. In the cross-sectional view, the cup-shaped portion 30 has an inverted cup shape that widens towards the bottom.

[0013] The main body 20 is attached to the lower end of a cane (not shown). The main body 20 is a substantially cylindrical shape that tapers upward and has a hole 21 inside for inserting the lower end of the cane. This hole 21 constitutes a cylindrical cavity 22.

[0014] In cross-sectional view, the interior 31 of the cup-shaped portion 30 has a bulge 35 at its ceiling portion 31a that protrudes downward. This bulge 35 forms a recessed space 32 within the interior 31, which is a concave void. Preferably, the bulge 35 is curved such that its central portion, when viewed from the bottom, is positioned at the lowest point in cross-sectional view. In Figure 5, the recessed space 32 is preferably the space inside the interior 31, formed by the interior 31 and the bulge 35. Furthermore, "downward" may refer to the direction from the main body portion 20 to the cup-shaped portion 30.

[0015] In conventional cane tips, the top portion was flat, so when a load was applied, the inside of the cup would easily collapse, creating negative pressure and causing it to adhere to the ground. In contrast, the bulging portion 35 of the cane tip 10 of this embodiment is configured such that the top portion 31a of the interior 31 has a dome shape and protrudes downward. Therefore, when weight is applied to the cane tip 10 of this embodiment and the cup-shaped portion 30 is compressed, the bulging portion 35 makes contact with the ground first. As a result, the bulging portion 35 functions as a stopper, preventing the recessed space 32 from being excessively compressed.

[0016] Furthermore, the bulging portion 35, by contacting the ground, prevents the recessed space 32 from being divided into multiple spaces, or makes it difficult for a completely sealed state to form, thus limiting the volume change of the recessed space 32. Therefore, the generation of negative pressure from the cup-shaped portion 30 is suppressed, and even on wet tiles or smooth ground, the tip 10 can be smoothly removed from the ground without sticking. In this way, the dome-shaped bulging portion 35 in the recessed space 32 prevents the recessed space 32 in the cup-shaped portion 30 from being reduced more than necessary, and by contacting the ground, it can suppress the generation of negative pressure within the recessed space 32. Thus, the tip 10 for the walking stick of this embodiment can eliminate the suction phenomenon that was a problem with conventional cup-shaped tips. [Explanation of Symbols]
