Description

Technical Field

[0001] This invention relates to the field of cane base technology, and more specifically, to a cane base for use on rough terrain. Background Technology

[0002] As people age, many physiological functions decline. The sense of touch may become drastically dulled after the age of 55. The decline in the structure that manages balance leads to instability in posture and gait, which increases the likelihood of falls. Although the canes currently used by the elderly are convenient to use.

[0003] A cane is a simple device to assist walking, usually a wooden or metal stick. Canes are an important medical rehabilitation aid, including hand canes, elbow canes, and armpit canes, with hand canes mainly used for mild needs.

[0004] Canes are generally suitable for use on relatively flat surfaces. If the road is uneven, the force applied to the cane changes, shifting the user's center of gravity and making them more prone to falls and injuries. In the event of sharp objects on the road, it could even be life-threatening. Existing canes, in an attempt to address these issues, incorporate a base. However, the cane and base are integrated, resulting in poor flexibility for different cane models. Furthermore, these canes are expensive and have low economic value. Summary of the Invention

[0005] The technical problem to be solved by this invention is:

[0006] To address the issue that canes can easily cause users to fall and endanger their health on uneven roads, existing canes are designed with the base as a single unit, which makes them unsuitable for changing between different cane models and results in poor flexibility.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0008] This invention provides a cane base for rough terrain, comprising a balance frame, a set of circumferentially arranged anti-slip shaped pieces, a cane holder, a brake ring, and a brake body. The upper end of the cane holder has a cane mounting groove, and the lower end of the cane holder is open and has an anti-slip cavity. Each anti-slip shaped piece has a sliding groove in its center. The balance frame has a structure for each anti-slip shaped piece to pass through and move up and down along the balance frame. The upper part of each anti-slip shaped piece is located within the anti-slip cavity. The upper end of the balance frame has a brake ring, which includes an integrally formed friction plate and a base. The friction plate is... The device includes a brake opening, and a base is located at the lower end of the friction pad opposite to the brake opening. The center of the inner wall of the top of the anti-slip cavity is connected to the center of the upper end of the balance frame by an elastic element. It also includes a brake body, one end of which is connected to the inner wall of the top of the anti-slip cavity. The position of the brake body is opposite to the position of the brake opening. When the cane base leaves the ground, the end of the brake body is located above the brake opening; when the cane is pressed down, the end of the brake body is located at the brake opening, so that the anti-slip shaping plate applies a radial expansion force to the side wall of the anti-slip cavity to fix the cane base and prevent the cane placement seat from tilting.

[0009] Furthermore, the anti-slip cavity has a circular cross-section, and the balance frame is a circular balance frame, with the outer diameter of the circular balance frame being larger than the inner diameter of the anti-slip cavity.

[0010] Furthermore, the structure on the balance frame through which each anti-slip shaping piece passes and can move up and down along the balance frame includes shaping piece mounting slots and sliding pieces. Both sides of the sliding piece have shaping piece mounting slots. A group of anti-slip shaping pieces are sequentially mounted on the sliding piece along its extension direction. The sliding piece sequentially passes through the sliding slots of several anti-slip shaping pieces. The shaping piece mounting slot is an arc-shaped slot. Two sets of arc-shaped slots are radially arranged on the circular balance frame. Each set of arc-shaped slots includes two oppositely arranged arc-shaped slots with the same center position; or each set of arc-shaped slots includes one oppositely arranged arc-shaped slot; or the structure on the balance frame through which each anti-slip shaping piece passes and can move up and down along the balance frame includes several anti-slip shaping piece mounting openings, with the side walls of the sliding slots of the anti-slip shaping pieces respectively passing through two adjacent mounting openings.

[0011] Furthermore, the brake ring is connected to the balance frame via a rotating shaft, the brake ring is located between two sets of arc-shaped grooves, and the distance between the free end of the friction plate and the balance frame matches the height of the base.

[0012] Furthermore, the length of the brake body is less than the length of the spring in its initial state. The brake body includes a connecting rod and a teardrop-shaped brake element. One end of the connecting rod is connected to the inner wall of the top of the anti-slip cavity, and the other end of the connecting rod is connected to the teardrop-shaped brake element. The end of the teardrop-shaped brake body is flush with the bottom of the cane holder.

[0013] Furthermore, the upper diameter of the teardrop-shaped brake component is greater than the length of the brake opening.

[0014] Furthermore, the upper diameter of the teardrop-shaped brake component is 1.5 to 3 times the length of the brake opening.

[0015] Furthermore, the teardrop-shaped brake component is an elastic teardrop-shaped brake component.

[0016] Furthermore, the bottom of the anti-slip forming piece is provided with an anti-slip base.

[0017] Furthermore, the elastic element is a spring, the elastic teardrop-shaped brake element is a rubber teardrop-shaped brake element, and the anti-slip bottom is a rubber anti-slip bottom.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention discloses a cane base for rough terrain. A balance frame is fitted with several anti-slip shaped pieces, and a sliding piece passes sequentially through the sliding grooves of the anti-slip shaped pieces. The balance frame has friction plates. The cane holder is connected to the balance frame via a central elastic element. The friction plates have brake openings. The upper wall of the anti-slip cavity of the cane holder has a brake body located at the brake opening. When the cane base leaves the road surface, the brake body is positioned above the brake opening, and the anti-slip shaped pieces are suspended from the sliding pieces by the upper wall of the sliding grooves. When the cane base contacts the road surface, whether on a smooth or rough surface, the upper wall of the anti-slip cavity contacts the upper surface of the higher anti-slip shaped pieces. The balance frame is located at the bottom of the sliding groove of the higher anti-slip shaped pieces. The cane holder applies a pushing force from the brake body to the friction plates, causing the friction plates to deform and compress the surrounding anti-slip shaped pieces, thereby compressing the inner wall of the anti-slip cavity. This prevents the cane holder and the balance frame from shifting and maintains a horizontal position relative to the road surface.

[0020] This invention is applicable to both smooth and rugged roads. The entire base of the cane can change shape at will according to the terrain. The cane base always remains horizontal with the road surface, providing stable and balanced support for the cane. It can maintain balance even on uneven roads, preventing slipping or tilting, thus improving the safety of the cane.

[0021] Since the base of the cane is easily worn and is a consumable, this base can be modified to change the inner diameter of the cane mounting slot, making it suitable for most canes on the market. It is convenient and flexible. Compared to a cane and cane base that are set up as a whole, only the base needs to be replaced, which can reduce the cost of use and is economical.

[0035] In the description of this invention, it should be noted that the terms used in the various embodiments, such as "upper," "lower," "front," "rear," "left," and "right," which indicate orientation, are only used to simplify the description of the positional relationships based on the accompanying drawings and do not mean that the components and devices referred to must be operated in accordance with the specific orientations and defined operations, methods, and structures in the specification. Such directional terms do not constitute a limitation of this invention.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Specific Implementation Plan 1: Combining Figures 1 to 11 As shown, the present invention provides a cane base for rough roads, including a balance frame 2, a set of anti-slip shaped pieces 1 arranged in a circle, a cane holder 5, a brake ring 4, and a brake body 3. The upper end of the cane holder 5 is provided with a cane mounting groove 5-1, and the lower end of the cane holder 5 is open and provided with an anti-slip cavity 5-2. The anti-slip shaped pieces 1 have a sliding groove 1-2 in the middle. The balance frame (2) is provided with a structure for each anti-slip shaped piece (1) to pass through and to move up and down along the balance frame (2). The upper part of the anti-slip shaped piece 1 The anti-slip shaping pieces 1 are located within the anti-slip cavity 5-2, meaning that a portion of the anti-slip shaping piece 1 is located within the anti-slip cavity 5-2 when the anti-slip shaping piece 1 moves up and down. The upper end of the balance frame 2 is provided with a brake ring 4, which includes an integrally formed friction piece 4-1 and a base 4-3. The friction piece 4-1 has a brake opening 4-4, and the lower end of the friction piece 4-1, opposite to the brake opening 4-4, is provided with the base 4-3. The center of the inner wall at the top of the anti-slip cavity 5-2 is connected to the center of the upper end of the balance frame 2 by an elastic element. The system also includes a brake body. 3. One end of the brake body 3 is connected to the inner wall of the top of the anti-slip cavity 5-2, and the other end of the brake body 3 is opposite to the position of the brake opening 4-4. When the cane base leaves the road surface, the brake body 3 is located above the brake opening 4-4, and the anti-slip shaping piece 1 is suspended on the sliding piece 2-2 through the upper wall of the sliding groove 1-2. At this time, the spring 6 is not subjected to the pressure of the cane. When the cane base contacts the road surface, under the condition of a smooth road surface or a rough road surface, the cane placement seat 5 and the balance frame 2 fall. During this process, the spring 6 is not subjected to the compressive force. When the cane is subjected to the pressure of the cane placement seat 5 by the cane, the spring 6 is not subjected to the compressive force. When pressure is applied, the upper wall of the anti-slip cavity 5-2 contacts the upper end face of the highest anti-slip shaping piece 1, and the balance frame 2 is located at the bottom of the sliding groove 1-2 of the highest anti-slip shaping piece 1. At this time, the bottom end of the cane placement seat 5 contacts the balance frame 2, compressing the spring 6. The brake body 3 moves down and applies a pushing force to the friction plate 4 through the cane placement seat 5, causing the friction plate 4 to deform and squeeze the surrounding anti-slip shaping pieces 1, thereby squeezing the inner wall of the anti-slip cavity 5-2, so that the cane placement seat 5 and the balance frame 2 do not shift and remain horizontal with the road surface.

[0038] in, Figure 2 This is the state when the base of the cane is off the ground. Figure 3 This refers to the state of the cane when it is on a flat surface. Figure 4 This refers to the state of the cane when it is on a rough surface.

[0039] Suitable for both smooth and rough roads 7, the entire base of the cane changes shape at will according to the terrain, the cane holder 5 always remains horizontal with the rough road 7, providing stable and balanced support for the cane, and can maintain balance on uneven roads, without slipping or tilting, thus improving the safety of the cane.

[0040] Since the cane base is easily worn and is a consumable, the inner diameter of the cane mounting slot 5-2 of the cane holder 5 can be changed, which is suitable for most canes on the market. It is convenient and flexible. Compared with the cane and cane base set as one piece, only the base needs to be replaced, which can reduce the cost of use and has economic benefits.

[0041] Specific Implementation Plan Two: Combining Figures 1 to 11 As shown, the anti-slip cavity 5-2 has a circular cross-section, and the balance frame 2 is either a circular balance frame 2 or an elliptical balance frame 2. The shape of the cross-section of the anti-slip cavity 5-2 matches the cross-section of the balance frame 2, and the outer diameter of the circular balance frame 2 is larger than the inner diameter of the anti-slip cavity 5-2. Other combinations and connections in this embodiment are the same as in specific embodiment one.

[0042] Specific Implementation Plan Three: Combining Figures 1 to 11 As shown, the structure on the balance frame 2 that allows each anti-slip shaping piece 1 to pass through and move up and down along the balance frame 2 includes a shaping piece mounting groove 2-1 and a sliding piece 2-2. Both sides of the sliding piece 2-2 are shaping piece mounting grooves 2-1. A group of anti-slip shaping pieces 1 are sequentially mounted on the sliding piece 2-2 along the extension direction of the sliding piece 2-2. The sliding piece 2-2 sequentially passes through the sliding grooves 1-2 of several anti-slip shaping pieces 1. The shaping piece mounting groove 2-1 is an arc-shaped groove. Two sets of arc-shaped grooves are radially arranged on the circular balance frame 2. Each set of arc-shaped grooves includes two oppositely arranged arc-shaped grooves with the same center position; or each set of arc-shaped grooves includes one oppositely arranged arc-shaped groove; or the structure on the balance frame 2 that allows each anti-slip shaping piece 1 to pass through and move up and down along the balance frame 2 includes several anti-slip shaping piece 1 mounting openings. The side walls of the sliding grooves 1-2 of the anti-slip shaping piece 1 pass through two adjacent mounting openings respectively. The other combinations and connections in this implementation scheme are the same as in Specific Implementation Scheme Two.

[0043] Preferably, the shape of the side wall of the anti-slip shaping piece 1 near the shaping piece mounting groove 2-1 matches the shape of the side wall of the shaping piece mounting groove 2-1 or the side wall of the mounting opening.

[0044] Preferably, the sliding groove 1-2 has an opening at the bottom of the anti-slip forming piece 1. During assembly, the anti-slip forming piece 1 can be assembled onto the sliding piece 2-2 or the partition between two adjacent mounting openings through the opening at the bottom of the sliding groove 1-2. Since the height of the anti-slip cavity 5-2 is less than the height of the anti-slip forming piece 1, it cannot be dislodged from the anti-slip cavity 5-2 when the anti-slip forming piece 1 moves upward.

[0045] Furthermore, each anti-slip forming piece 1 has a removable end cap at its bottom.

[0046] Specific Implementation Plan Four: Combining Figures 1 to 11 As shown, the brake ring 4 and the balance frame 2 are connected by a rotating shaft 4-2, which is located between two arc-shaped grooves on the periphery. The distance between the free end of the friction plate 4-1 and the balance frame 2 is less than or equal to the height of the base 4-3, providing space for the brake body 3 to enter the brake opening 4-4. When the brake body 3 enters the brake opening 4-4 ​​to its maximum distance, the end of the brake body 3 contacts the upper surface of the balance frame 2. Other combinations and connections in this embodiment are the same as in specific embodiment three.

[0047] Preferably, the arc length of the base 4-3 is 1 / 9 to 1 / 8 of the arc length of the friction plate 4-1.

[0048] Specific Implementation Plan Five: Combining Figures 1 to 11 As shown, the length of the brake body 3 is less than the initial length of the spring 6. When the cane base leaves the ground, since the length of the spring 6 is greater than the length of the brake body 3, the brake body 3 is located above the friction plate 4-1 and does not generate a radial expansion force on the friction plate 4-1. When the cane base is on the ground, the brake body 3 enters the brake opening 4-4 ​​by squeezing the spring 6, generating a radial expansion force on the friction plate 4-1. The brake body 3 includes a connecting rod 3-2 and a teardrop-shaped brake element 3-1. One end of the connecting rod 3-2 is connected to the inner wall of the top of the anti-slip cavity 5-2, and the other end of the connecting rod 3-2 is connected to the teardrop-shaped brake element 3-1. The upper diameter of the teardrop-shaped brake element 3-1 is greater than the length of the brake opening 4-4. The teardrop-shaped brake element 3-1 is an elastic teardrop-shaped brake element. Other combinations and connections in this embodiment are the same as in specific embodiment four.

[0049] Preferably, the upper diameter of the teardrop-shaped brake element 3-1 is 1.5 to 3 times the length of the brake opening 4-4.

[0050] Specific Implementation Plan Six: Combining Figures 1 to 11 As shown, the bottom of the anti-slip forming piece 1 is provided with an anti-slip base 1-1, which is used to increase the friction with the road surface and prevent falls due to the slippery road surface. Other combinations and connections in this embodiment are the same as in specific embodiment five.

[0051] Specific Implementation Plan Seven: Combining Figures 1 to 11 As shown, the elastic element is spring 6, the elastic teardrop-shaped brake element is rubber teardrop-shaped brake element, and the anti-slip bottom 1-1 is rubber anti-slip bottom. Other combinations and connections in this embodiment are the same as in specific embodiment six.

[0052] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
