Description

Technical Field

[0001] This utility model relates to the field of wheelchair equipment, and in particular to a wheelchair leg exercise device. Background Technology

[0002] Wheelchairs are an important tool for rehabilitation, enabling people with disabilities to live independently. However, many patients experience a decline in bodily functions due to prolonged wheelchair use, which can even worsen their condition. Traditional wheelchairs generally have limited functionality and insufficient rehabilitation assistance, especially for patients who are bedridden or have limited mobility. Their leg functions gradually deteriorate, and their muscles atrophy. Each time they exercise, they need to move to the exercise device via wheelchair, which is very inconvenient and prevents them from exercising anytime and anywhere. Utility Model Content

[0003] The purpose of this invention is to provide a wheelchair leg exercise device to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A wheelchair leg exercise device includes a crossbar, a movable part, and a pedal. One end of the movable part is slidably mounted with a long shaft, and the other end is connected to the crossbar. The lower end of the long shaft is fixedly connected to a fixing head, and the pedal is fixedly mounted on the fixing head. The lower end of the crossbar is hinged to an impedance slide cylinder, and an impedance slide column is hinged to the movable part. The impedance slide column is slidably connected in the impedance slide cylinder.

[0006] Preferably, a damping head is fixedly installed on the impedance slide, and the outer side of the damping head is in frictional contact with the inner cavity sidewall of the impedance slide.

[0007] Preferably, a connecting part is fixedly installed on the long shaft portion, and the connecting part is slidably embedded in the inner cavity of the movable portion.

[0008] Preferably, an adjustable retractable belt is installed between the fixing head and the pedal.

[0009] Preferably, the upper surface of the pedal is provided with elongated protrusions.

[0010] The advantages and positive effects of this utility model are:

[0011] This invention utilizes an innovative leg exercise device to actively train calf muscles, simulating walking motions to enhance patient mobility. Utilizing the frictional resistance design of the damping head and impedance slide, it provides adjustable impedance training, significantly improving muscle training effectiveness. Simultaneously, it can adapt to different leg lengths and fixation requirements, enhancing safety and comfort. The simple and reliable structure achieves efficient rehabilitation training without the need for a complex power system, catering to both home care and medical institution needs.

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of front, back, left, right, up, and down in the view are consistent.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:

[0025] Please see Figure 1-7 This utility model provides an embodiment of a wheelchair, including a wheel assembly 1 at the bottom, two leg exercise devices 2, a seat device 3 for easy care, and a foldable and adjustable backrest device 4. The foldable and adjustable backrest device 4 is mounted on the bracket of the wheel assembly 1, and the seat device 3 for easy care is mounted between the crossbars 201 of the two leg exercise devices 2. This allows the patient to exercise their legs through the leg exercise devices 2 when sitting in the wheelchair, thereby avoiding the weakening of leg functions caused by prolonged sitting and enhancing rehabilitation.

[0026] The leg exercise device 2 can be configured to perform a leg flexion exercise around the knee joint, simulating a walking motion pattern, thereby strengthening the mobility of sedentary patients. (See below for reference.) Figures 1-6 The following will describe in detail the leg flexion exercise performed by the leg exercise device 2 on the lower leg around the knee joint;

[0027] The leg exercise device 2 includes a crossbar 201, a movable part 202, and a pedal 207. One end of the movable part 202 is hinged to the crossbar 201, and the other end is connected to a long shaft 205. A fixing head 206 is fixedly connected to the lower end of the long shaft 205, and the pedal 207 is fixedly mounted on the fixing head 206. An impedance slide cylinder 203 is hinged to the lower end of the crossbar 201, and an impedance slide column 204 is hinged to the movable part 202. The impedance slide column 204 is slidably connected in the impedance slide cylinder 203, fixing the patient's foot on the pedal 207 and using a forward kick of the lower leg. To enhance leg training, and to make the training more effective, the telescopic sliding of the impedance slide column 204 and the impedance slide cylinder 203 can be configured to have a certain frictional resistance. This allows the application of resistance when the patient kicks forward with their lower leg, thereby further improving the training effect. Specifically, a damping head 209 is fixedly installed on the impedance slide column 204. The outer surface of the damping head 209 is in frictional contact with the inner wall of the impedance slide cylinder 203. The damping of the damping head 209 allows the patient to apply a certain resistance when kicking forward with their lower leg and when returning to the starting position, thereby further improving the training effect.

[0028] A connecting part 210 is fixedly installed on the long shaft portion 205. The connecting part 210 is slidably embedded in the inner cavity of the movable part 202, so that the long shaft portion 205 can be extended and retracted to adapt to the leg length of different people.

[0029] Meanwhile, an adjustable retractable strap 208 is installed between the fixing head 206 and the pedal 207. The adjustable retractable strap 208 can effectively fix the foot position. At the same time, the long strip protrusions distributed on the upper surface of the pedal 207 greatly improve the stability of the foot position, making it safer for patients to perform leg exercises.

[0030] In practice, the patient sits on the convenient seat 3 with both feet on the corresponding pedals 207. By adjusting the adjustable retractable band 208 to tighten the feet, the patient can kick forward and raise their lower leg. This causes the movable part 202 to swing forward. Simultaneously, as the impedance slide column 204 slides within the inner cavity of the impedance slide cylinder 203, the outer surface of the damping head 209 rubs against the inner wall of the impedance slide cylinder 203. The damping of the damping head 209 allows the patient to apply a certain resistance during the forward kick and return to the starting position, thereby increasing resistance training during exercise, which is more conducive to muscle growth and greatly improves the training effect.

[0031] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
