Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a multifunctional walking wheel mechanism for a walker for the elderly. Background Art

[0002] Currently, most walkers for the elderly on the market have wheels or cushions underneath their uprights. If they have wheels, they are prone to moving when the patient stops walking, causing the walker to slide and making it inconvenient to rest in place. If they have cushions, the patient needs to move the walker, which is also inconvenient. The present invention combines both, allowing patients to choose the method of use according to their needs. Utility Model Content

[0003] The main purpose of the utility model is to provide a multifunctional walking wheel mechanism for an elderly walker, so as to effectively solve the problems raised in the background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a multifunctional elderly walker wheel mechanism, comprising a column circular tube, a horizontal spring hanging rod is provided at the bottom of the column circular tube and is inserted into the side wall of the column circular tube, a vertical long groove is provided on each side of the column circular tube corresponding to the upper side of the spring hanging rod, a wheel axle is fitted in the vertical long groove, a hanging hole is provided in the middle of the wheel axle, the upper end of a spring is hung in the hanging hole, the lower end of the spring is hung on the spring hanging rod, a wheel is installed at each end of the wheel axle, and a wheel is fitted in the lower end of the column circular tube. A tubular sleeve is provided with an upper and lower small hole penetrating the column circular tube in the direction perpendicular to the vertical long slot. The small hole on the lower side is a limit card hole, and the small hole on the upper side is a spare hole. There is also a limit card, which is a section of Ω-shaped tubular structure. A square notch is provided on each side of the upper part, and a card shaft is fixed in the middle. The card shaft can be inserted into the limit card hole and the spare hole respectively. At this time, the Ω-shaped tubular structure is clamped on the outside of the column circular tube, the limit card hole is located within the length of the vertical long slot, and the spare hole is located on the upper side of the vertical long slot.

[0005] Preferably, when the elderly use the walker in wheel mode to walk, the axis of the limit clip is inserted into the spare hole, and the wheel can move up and down to play a buffering role. When the elderly sit on the walker, the gravity is greater than the spring tension. At this time, the pad touches the ground, increasing the friction and making the walker less likely to slide.

[0006] Preferably, when the elderly walker uses the sleeve pad mode, the clamping shaft of the limiting clamp is inserted into the limiting clamp hole, so that the wheel axle is located above the clamping shaft, the wheel is off the ground, the sleeve pad touches the ground, and the wheel axle is located in the gap above the limiting clamp.

[0007] Preferably, the sleeve pad is made of rubber.

[0008] Preferably, when the clamp shaft of the limiting clamp is inserted into the spare hole, the lowest point of the limiting clamp is higher than the highest point of the vertical long slot.

[0009] When using the walker for the elderly, if you use the wheel mode, insert the limit clip into the spare hole. If you use the cushion mode, insert the limit clip into the limit card hole. The two modes can be switched at will.

[0010] The beneficial effects of the utility model include: the wheel mode and the cushion mode can be switched at will, which is convenient for the elderly to use; and when using the wheel mode, if the elderly sit on the walker, the cushion touches the ground, increasing the friction between the walker and the ground, making the walker less likely to slide; or during movement, when the downward force is greater than the spring tension, the cushion touches the ground, increasing the friction between the walker and the ground, making it less likely for the user to slip.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Example 1

[0019] Attachment Figure 1As shown in FIG5 , a multifunctional elderly walker wheel mechanism comprises a column circular tube 1, a horizontal spring hanging rod 8 is provided at the bottom of the column circular tube 1 and is inserted into the side wall of the column circular tube, the column circular tube 1 is provided with a vertical long groove 7 on both sides corresponding to the spring hanging rod 8, a wheel axle 3 is sleeved in the vertical long groove 7, a hanging hole 6 is provided in the middle of the wheel axle 3, the upper end of a spring 5 is hung in the hanging hole 6, and the lower end of the spring 5 is hung on the spring hanging rod 8, a wheel 2 is installed at each end of the wheel axle 3, a tubular sleeve 4 is sleeved at the lower end of the column circular tube 1, and a wheel 2 is installed at each end of the wheel axle 3. Two small holes, one on the upper side and one on the lower side, are provided perpendicular to the vertical slot 7 and penetrate the column tube 1. The small hole on the lower side is a limit clamping hole 9, and the small hole on the upper side is a spare hole 11. There is also a limit clamp 10. The limit clamp 10 is a section of Ω-shaped tubular structure. Each of the upper side surfaces is provided with a square notch, and a clamping shaft 12 is fixedly provided in the middle. The clamping shaft 12 can be inserted into the limit clamping hole 9 and the spare hole 11 respectively. At this time, the Ω-shaped tubular structure is clamped to the outside of the column tube 1. The limit clamping hole 9 is located within the length of the vertical slot 7, and the spare hole 11 is located on the upper side of the vertical slot 7.

[0020] When the elderly use the walker in wheel mode, the card shaft 12 of the limit clip 10 is inserted into the spare hole 11, and the wheel 2 can move up and down to play a buffering role. When the elderly sit on the walker, the gravity is greater than the tension of the spring 5. At this time, the cushion 4 touches the ground, increasing the friction, and the walker is not easy to slide.

[0021] When the elderly walker uses the cushion mode, the clamping shaft 12 of the limiting clip 10 is inserted into the limiting clamping hole 9, so that the wheel axle 3 is located above the clamping shaft 12, the wheel 2 is off the ground, the cushion 4 touches the ground, and the wheel axle 3 is located in the gap above the limiting clip 10.

[0022] The sleeve pad 4 is made of rubber.

[0023] When the clamping shaft 12 of the limiting clamp 10 is inserted into the spare hole 11 , the lowest point of the limiting clamp 10 is higher than the highest point of the vertical long slot 7 .

[0024] When using the walker for the elderly, if the wheel mode is used, the limiting clip 10 is inserted into the spare hole 11, and if the cushion mode is used, the limiting clip 10 is inserted into the limiting clip hole 9. The two modes can be switched at will.

[0025] The beneficial effects of the utility model include: the wheel mode and the cushion mode can be switched at will, which is convenient for the elderly to use; and when using the wheel mode, if the elderly sit on the walker, the cushion touches the ground, increasing the friction between the walker and the ground, making the walker less likely to slide; or during movement, when the downward force is greater than the spring tension, the cushion touches the ground, increasing the friction between the walker and the ground, making it less likely for the user to slip.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
