Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, specifically a four-legged support crutch designed for people with limited knee joint mobility, namely a four-legged walking assistive crutch with a footrest platform and a 90-degree rotation mechanism. Background Technology

[0002] Compared to traditional canes, four-legged canes offer numerous benefits for outdoor activities, such as improved walking stability and reduced leg strain. Using four-legged canes while walking reduces the strain on muscles and joints like the legs and knees, making walking more comfortable. They also offer height adjustment and stable four-legged support. However, current four-legged canes have the following drawbacks:

[0003] The four-legged base has a single function, and its standard dimensions are generally 30cm in length and 20.5cm in width. It is only used for ground support and cannot meet the need for stepping up or down stairs. Directional adjustment is limited: the support rod often uses a double-ball structure, supporting only vertical height and left / right hand grip adjustment, which is unsuitable for the grip method when the base is used for stepping. Lack of flexibility: when walking on the ground, the length direction is generally consistent with the direction of movement, making it easy to use the cane for walking. However, when going up or down stairs, such as... Figure 1 The walking direction dimension of the ordinary four-legged base 1 shown is often wider than the width dimension of the stair step 2. It is necessary to change the direction of the four-legged base to climb the ladder. The change of direction will also cause the handle to change direction, which will reduce the comfort and stability of the cane.

[0004] To this end, the inventors conducted beneficial explorations and attempts, and found a solution to the above problems. The solution to be introduced below was developed under this background. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a four-legged walking aid with a footrest platform and a 90-degree rotation mechanism to address the shortcomings and defects of the existing technology.

[0006] The technical problem solved by this utility model can be achieved by the following technical solution:

[0007] A four-legged walking aid with a footrest platform and a 90-degree rotation mechanism includes a four-legged base and a walking stick body. The walking stick body includes a handle at the top and a support rod that is telescopically connected to the handle. The other end of the support rod is connected to the four-legged base, and a grip is connected to the top of the handle. The four-legged base has a footrest platform welded to its upper surface. Multiple circular holes are formed along the length of the handle. A limiting single-headed pressing ball is set inside the support rod and perpendicular to the rotation axis of the support rod. When the limiting single-headed ball engages with the circular holes, the handle rotates 90 degrees.

[0008] In a preferred embodiment of this utility model, a stainless steel U-shaped frame is welded to the upper surface of the four-legged base to form a foot platform.

[0009] In a preferred embodiment of this utility model, a thin steel plate is welded to the upper surface of the four-legged base to form a foot platform.

[0010] In a preferred embodiment of this utility model, a limiting double-headed pressing ball is also provided inside the support rod. The limiting double-headed pressing ball is located above the limiting single-headed pressing ball, and the limiting double-headed pressing ball and the limiting single-headed pressing ball have their ball-shaped outward orientations perpendicular to each other. When the limiting double-headed pressing ball engages with the round hole, the support rod is fixed at a certain height position.

[0011] In a preferred embodiment of this utility model, a locking nut is provided at the telescopic connection between the grip rod and the support rod, and a fastening ring is provided inside the locking nut, which is sleeved on the outer surface of the grip rod and the support rod.

[0012] In a preferred embodiment of this utility model, the outer surface of the stainless steel U-shaped frame is provided with anti-slip texture.

[0013] In a preferred embodiment of this utility model, the four-legged base is 30cm long and 20.5cm wide, the U-shaped frame is 24cm long, 16cm wide, and 2mm thick.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] This invention relates to a four-legged support cane designed for people with limited knee joint mobility. It features a 90-degree rotating adjustment mechanism: a single-headed pressing ball is added below the horizontal position of the double-headed pressing ball. By pressing this ball, the hand grip is rotated around the support rod axis until it locks in place, achieving a lateral grip posture. This provides stability, ease of use, and comfort when descending stairs. A stainless steel U-shaped frame welded to the four-legged base provides a stepping platform. In summary, this invention solves the problems of difficulty in gaining leverage and awkward grip direction when going up and down stairs, possessing high stability and practicality.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0023] See Figure 2-5 As shown, this utility model discloses a four-legged walking aid with a footrest platform and a 90-degree rotation mechanism. It includes a four-legged base 10 and a walking stick body 20. The walking stick body 20 includes a handle 30 located above the walking stick body and a support rod 40 that is retractably connected to the handle 30. The other end, or bottom end, of the support rod 40 is welded or threaded to the four-legged base 10. The top of the handle 30 is connected to a grip 32. In this embodiment, the support rod 40 can extend into the handle 30. Specifically, this embodiment includes a limiting double-headed pressing ball 80 inside the support rod 40, comprising pressing balls 80a and 80b. When the limiting double-headed pressing ball 80 engages with the circular hole 31, the support rod 40 is fixed at a certain height. The orientation of the grip lever 30 and handle 32 can be controlled by pressing a ball bearing. In this embodiment, rotating the grip lever 30 to press the ball bearing 80b is suitable for holding the cane with the right hand; rotating the grip lever 30 to press the ball bearing 80a is suitable for holding the cane with the left hand. The components related to the ball bearing are precision stamped and pre-lubricated during assembly to reduce friction.

[0024] To further enhance the stability of the cane, a rotary fixing valve or a locking nut 50 is provided at the telescopic connection between the grip bar 30 and the support bar 40. The locking nut 50 has a fastening ring (not shown in the figure) inside, which is fitted onto the outer surface of the support bar 40. Since the rotary fixing valve and locking nut are existing designs, they will not be described in detail here.

[0025] To overcome the deficiency of existing four-legged cane bases in not being able to provide foot support for climbing stairs, in this embodiment of the invention, a foot platform 60 is welded to the upper surface of the four-legged base 40. The foot platform 60 is formed by welding a stainless steel U-shaped frame 61 to the upper surface of the four-legged base 40, or by welding a thin steel plate to the upper surface of the four-legged base 40. In this embodiment, the four-legged base 40 is 30cm long and 20.5cm wide, and the stainless steel U-shaped frame 61 is 24cm long, 16cm wide, and 2mm thick. The outer surface of the stainless steel U-shaped frame 61 has anti-slip textures. Argon arc welding is used to ensure a seamless connection between the stainless steel U-shaped frame and the four-legged base.

[0026] To allow patients to use the product of this embodiment to step up stairs with assistance while flexibly adjusting the position of the handgrip 30 and handle 32, this embodiment features at least one limiting single-headed pressing ball 70 located 3-5 cm below the limiting double-headed pressing ball 80, preferably 3.3 cm below. The limiting double-headed pressing ball 80 and the limiting single-headed pressing ball 70 are perpendicular to each other, and the limiting single-headed pressing ball 70 is positioned perpendicular to the rotation axis of the support rod 40. When the limiting single-headed pressing ball 70 is engaged and fixed with the circular hole 31, the handgrip 30 and handle 32 rotate 90 degrees. The limiting double-headed pressing ball 80 is primarily used for walking on the ground, while the limiting single-headed pressing ball 70 is mainly used for stepping up and down stairs. When going up and down stairs, the body generally leans forward, so the height of the cane needs to be slightly lower than when walking, making it more suitable for patients to step up stairs with assistance while comfortably gripping the handle.

[0027] In this embodiment of the invention, the cane body is made of aluminum alloy, and the handle surface is fitted with a sponge ring for comfortable use. The limiting double-headed pressing ball 80 and the limiting single-headed pressing ball 70 work in conjunction with the handgrip 30 in different scenarios, solving the problem of grip direction. It is not only convenient for walking on the ground but also suitable for going up and down stairs, possessing excellent stability and easy adjustment. A stainless steel U-shaped frame 61 welded to the four-legged base 10 provides a stepping platform, solving the problem of difficulty in gaining leverage when going up and down stairs, providing stability and versatility.
