Description

Technical Field

[0001] This utility model relates to the field of cane technology, and in particular to a roly-poly cane. Background Technology

[0002] A walking stick is a simple device to assist walking and is a common item for the elderly when going out. The walking sticks currently available on the market can only be uprighted by human intervention and cannot be uprighted automatically. Moreover, if the walking stick falls over, it is very difficult for people with mobility difficulties to pick it up.

[0003] Patent No. CN203182182U discloses a novel self-righting cane, including a cane handle, a handle at the top of the cane handle, a support pad at the bottom of the cane handle, and a connecting block on the support pad. The connecting block and the support pad form a self-righting structure, which can keep the cane handle upright, reduce the need to bend over to pick up the cane during use, and make it easier for people to use.

[0004] However, the existing roly-poly cane bases are all arc-shaped structures, with a small contact point between the cane base and the ground. The small contact area results in a small support area for the cane, making the cane less stable during use. Users may feel that the cane is easy to tilt or lose balance when walking, increasing the risk of falling. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a roly-poly cane to solve the problem of poor stability in the use of canes due to small contact area.

[0006] To achieve the above objectives, this utility model provides a self-righting walking stick, comprising a walking stick body and a self-righting sphere. The walking stick body includes a first walking stick and a second walking stick, with the second walking stick slidably connected inside the first walking stick. The lower end of the first walking stick is connected to the self-righting sphere. A locking mechanism for adjusting the size of the walking stick body is provided between the first and second walking sticks. The self-righting sphere is made of elastic rubber and has a hollow structure. A counterweight is installed at the bottom of the self-righting sphere. A support mechanism is provided on the outside of the self-righting sphere to provide stable support for the walking stick body.

[0007] A further improvement is that the locking mechanism includes multiple positioning holes on the side of the first staff, and an installation hole on the side of the second staff. A positioning pin is installed in the installation hole, the positioning pin is adapted to the positioning hole, and a pressing spring is connected between the positioning pin and the inner wall of the installation hole.

[0008] A further improvement is that the support mechanism includes a support shell and support rings. The upper end of the support shell is fixedly sleeved on the outer side of the lower end of the first rod, and the lower end of the support shell is sleeved on the outer side of the upper end of the roly-poly ball. Multiple support rings are provided, and the support rings are installed on the lower outer side of the roly-poly ball.

[0009] A further improvement is that the support ring is a plurality of concentrically arranged circular rings, with the diameter of the support rings increasing sequentially from bottom to top, and the diameter of the uppermost support ring being smaller than the diameter of the opening at the lower end of the support shell.

[0010] A further improvement is that both the support shell and the support ring have an anti-slip layer on their surfaces.

[0011] A further improvement is that an elastic support bar is provided inside the roly-poly ball; and a buffer spring is connected between the lower end of the first rod and the counterweight.

[0012] The beneficial effects of this utility model are as follows: By adopting a hollow roly-poly structure, the bottom of the cane will be deformed under pressure during use, thereby increasing the contact area with the ground and improving the stability of use; the support mechanism, with support rings and support shells providing rigid support, ensures that the lower end of the cane remains stable in contact with the ground, and the support rings limit the contraction of the lower end of the roly-poly sphere, so that after the roly-poly sphere is compressed and contracted, the multiple support rings increase the friction with the ground, thereby improving the stability of the cane in use.

[0013] The roly-poly ball is equipped with elastic support bars, which support the inside of the roly-poly ball to ensure its stability when placed and keep the roly-poly cane upright. The buffer spring cushions the cane, reducing the force transmitted to the hand during use and improving comfort. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figure 1-4As shown, a self-righting walking stick includes a walking stick body 1 and a self-righting sphere 2. The walking stick body 1 includes a first walking stick 3 and a second walking stick 4. The walking stick body 1 is made of lightweight materials, such as aluminum alloy or carbon fiber, and both the first walking stick 3 and the second walking stick 4 have hollow internal structures to reduce the overall weight of the walking stick. The second walking stick 4 is slidably connected inside the first walking stick 3. The lower end of the first walking stick 3 is connected to the self-righting sphere 2, and a handle is installed on the upper end of the second walking stick 4. A locking mechanism for adjusting the size of the walking stick body 1 is provided between the first walking stick 3 and the second walking stick 4. The locking mechanism includes multiple positioning holes 6 opened on the side of the first walking stick 3. The second rod 4 has a mounting hole 7 on its side, and a positioning pin 8 is installed in the mounting hole 7. The outer end of the positioning pin 8 has a spherical structure and is adapted to the positioning hole 6. A pressing spring 9 is connected between the positioning pin 8 and the inner wall of the mounting hole 7. By pressing the positioning pin 8, the pressing spring 9 is contracted, and the positioning pin 8 moves into the mounting hole 7 and disengages from the mounting hole 7. This pulls the second rod 4 and adjusts its position within the first rod 3. After adjustment, the positioning pin 8 is released, and the pressing spring 9 pushes the positioning pin 8 into the positioning hole 6 for positioning, thereby locking the first rod 3 and the second rod 4 to ensure stability in subsequent use.

[0024] like Figure 3 As shown, the roly-poly sphere 2 is made of elastic rubber and has a hollow structure. Elastic support bars 12 are installed inside the roly-poly sphere 2, with the elastic support bars 12 arranged alternately horizontally and vertically. A buffer spring 13 connects the lower end of the first cane to the counterweight 5. A through hole is opened in the middle of the horizontally arranged elastic support bars 12, through which the buffer spring 13 passes. When the cane is placed, the elastic support bars 12 and the buffer spring 13 support the interior of the roly-poly sphere 2, keeping it stable and preventing it from tipping over. The roly-poly sphere 2 deforms, allowing it to be placed stably. This stable placement keeps the cane body 1 upright, facilitating its use. During use, the buffer spring 13 and elastic support bar 12 provide a cushioning force to the cane body 1, reducing the impact force between the cane body 1 and the ground, making the cane more comfortable to use. Furthermore, the buffer spring 13 and elastic support bar 12 provide a force acting on the support ring 11, causing the support ring 11 to conform to the ground, increasing the friction between the support ring 11 and the ground, and improving stability.

[0025] A counterweight 5 is installed at the bottom of the roly-poly ball 2 to stabilize the center and prevent the cane from falling over. A support mechanism is provided on the outside of the roly-poly ball 2 to provide stable support for the main body of the cane. The support mechanism includes a support shell 10 and a support ring 11. The upper end of the support shell 10 is fixedly sleeved on the outside of the lower end of the first cane 3, and the lower end of the support shell 10 is sleeved on the outside of the upper end of the roly-poly ball 2. Multiple support rings 11 are provided and are installed on the lower outside of the roly-poly ball 2. The support ring 11 consists of multiple concentrically arranged circular rings, with the diameter of the support ring 11 increasing sequentially from bottom to top. The diameter of the uppermost support ring 11 is smaller than the diameter of the opening at the lower end of the support shell 10. When the cane is in use, the downward force applied to the cane and the force from the ground cause the lower end of the roly-poly sphere 2 to deform and contract inward. The support rings 11 contract inward one by one, forming a concentric circular structure with the support shell 10. The support shell 10 supports the cane body 1 from the outside, providing stable support force. The support rings 11 provide support force from the inside while increasing the contact area with the ground, making the cane more stable to use.

[0026] Both the support shell 10 and the support ring 11 are provided with an anti-slip layer. The anti-slip layer increases the friction of the support shell 10 and the support ring 11, making the support shell 10 and the support ring 11 more slip-resistant when in contact with the ground, thus improving the stability of use.

[0027] When placed, the roly-poly ball 2 is supported by the elastic support bar 12 and the buffer spring 13 to maintain its spherical state. The weight is determined by the counterweight 5, thus creating an effect that prevents it from tipping over, allowing the cane to be placed vertically. When in use, the user holds the cane body 1 and applies downward pressure. The roly-poly ball 2 is squeezed inward by the ground and contracts. The support ring 11 gradually folds to the same plane through the contraction. When the support ring 11 is folded to be horizontal with the lower end of the support shell 10, the support shell 10 contacts the ground and supports the cane body 1, providing stable support force. In addition, the inner support ring 11 moves in the opposite direction due to the force of the elastic support bar 12 and the buffer spring 13, so that the support ring 11 can stably fit on the ground, increasing the contact area with the ground and providing more stable support force, making the cane more stable to use.
