Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment, and in particular to a linkage fitness equipment based on lower limb exercise for the elderly. Background Art

[0002] With the advent of an aging society, the health of the elderly is receiving increasing attention. Falls are a common occurrence for community-dwelling elderly individuals with some degree of self-care. As they age, many middle-aged and elderly individuals experience a gradual decline in their physical functions, placing them at high risk of sustaining other physical injuries if they fall. Falls in the elderly are influenced by a variety of factors, with decreased lower limb muscle strength being a primary cause. This weakness can directly lead to falls and can also contribute to falls by impacting balance and walking ability. Therefore, engaging in physical exercise to strengthen lower limb muscles in the elderly has become a topic of widespread concern, improving their balance and coordination, preventing falls, and ultimately ensuring their health.

[0003] Traditional outdoor fitness equipment has problems such as low exercise efficiency and inability to effectively target the body. Most existing fitness equipment has a simple structure and cannot adjust the weight, which cannot meet the needs of users with different physical conditions. Indoor fitness equipment has high professional requirements. Most elderly people have not received professional training and may get injured when using indoor equipment. In addition, complex exercises require learning how to use the equipment, and the decline in the elderly's memory and limb coordination ability will cause them to invest too much time in learning, which can easily cause fatigue and aversion to exercise in the elderly.

[0004] For example, space walkers swing dramatically during use, which can easily cause hip injuries and put elderly people with poor balance at risk of falls. Exercise bikes lack resistance adjustment, and their seat design doesn't take into account the pelvic deformation characteristics of the elderly, which can easily cause coccyx pain. Elliptical walkers have a large range of motion and lack resistance grading, requiring high coordination and increasing the risk of injury in the elderly. Rowing machines, on the other hand, require lumbar flexion and extension, which can easily cause lumbar spine injuries in the elderly. Therefore, there is an urgent need to design an outdoor fitness device that uses a linkage structure to achieve targeted lower limb training and coordinated limb exercise for the elderly. Summary of the Invention

[0005] The main purpose of the present invention is to provide a linkage fitness device based on lower limb exercise for the elderly, so as to overcome the problems existing in the prior art.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A linkage fitness device based on lower limb exercise for the elderly, comprising a support component, a load-bearing component, a training component and a weight adjustment component, wherein the support component is connected to the load-bearing component to form a triangular support structure, the training component comprises a slide rail, a pedal, an armrest and a backrest, the support component comprises a base and a support column, the load-bearing component is obliquely connected between the base and the support column, the slide rail is slidably arranged on the load-bearing component, the backrest is fixedly arranged on the slide rail, the armrest is fixedly arranged on the backrest, and the pedal is fixedly arranged on the base.

[0008] Furthermore, the base adopts a U-shaped structure, a first cross bar is provided at the opening position of the base, a second cross bar is provided at the position below the first cross bar on the base, and the supporting column is connected to the end of the base away from the opening.

[0009] Furthermore, the load-bearing assembly includes two load-bearing guide columns, one end of each load-bearing guide column is connected to the second cross bar, and the other end is connected to the top of the support column.

[0010] Furthermore, there are two supporting columns, the tops of the two supporting columns are bent inward and connected to one end of the load-bearing guide column through a connecting plate, and the top of the second cross bar extends upward to form a curved connecting column and is connected to the other end of the load-bearing guide column.

[0011] Furthermore, the pedal is mounted on the base via a connecting frame, and the connecting frame is tilted on the base.

[0012] Furthermore, the inclination angle of the load-bearing guide column is 45°.

[0013] Furthermore, a waist pad is provided on the backrest.

[0014] Furthermore, the training component also includes a protective ring, which is connected to the backrest via a fixing rod.

[0015] Furthermore, the weight adjustment assembly includes a first weight rod and a second weight rod, the first weight rod is arranged on the support column, and the second weight rod is arranged on the slide rail, and the first weight rod and the second weight rod are both detachably provided with counterweight blocks.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By tilting the load-bearing component at 45°, the user can tilt the slide rail along the load-bearing guide column during training, reducing the peak pressure on the knee joint and thus reducing damage to the user's joints and other parts of the body. The lumbar pad can further prevent lumbar injuries caused by exertion in the elderly. The protective ring can ensure that the user is protected throughout the exercise, thereby reducing the risk of falls, ultimately improving the safety of the entire device.

[0018] By setting up the armrests and pedals of the training components, coordinated training of the hands and legs is achieved, so that the elderly can get targeted leg training while taking into account the training of upper limb strength, achieving the effect of limb linkage and coordinated fitness, not only improving the activation efficiency of the lower limb muscles, but also synchronously exercising the upper limb muscles;

[0019] By setting the weight adjustment component and the detachable counterweight block, the weight can be finely adjusted to adapt to different muscle strength levels. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] Combine Figures 1 to 4 This embodiment provides a linked fitness device for elderly people's lower limb exercises. With aging as the starting point, it provides a safe and efficient exercise device for the elderly, improving their fitness efficiency. The fitness device includes a support assembly, a load-bearing assembly 7, a training assembly, and a load-adjusting assembly. The support assembly and the load-bearing assembly 7 are connected to form a triangular support structure.

[0027] Among them, the supporting assembly includes a base 2 and a supporting column 8, and the load-bearing assembly 7 is obliquely connected between the base 2 and the supporting column 8; the training assembly includes a slide rail 3, a pedal 4, an armrest 5, a protective ring 6 and a backrest 9, the slide rail 3 is slidably set on the load-bearing assembly 7, the backrest 9 is fixedly set on the slide rail 3, the armrest 5 is fixedly set on the backrest 9, the protective ring 6 is connected to the backrest 9 through a fixed rod, and the pedal 4 is fixedly set on the base 2; the weight adjustment assembly includes a first weight rod and a second weight rod, the first weight rod is set on the supporting column 8, and the second weight rod is set on the slide rail 3, and the first weight rod and the second weight rod are both detachably provided with a counterweight 1.

[0028] Specifically, the counterweight 1 adopts a dumbbell plate set, which can provide 5 levels of resistance (1-5kg / plate) and adapt to different muscle strength levels of different users; the inclination angle of the load-bearing guide column is 45°, so that the inclination angle of the slide rail 3 during movement is also 45°, which can reduce the pressure on the knee joint by 30% compared with the vertical track; when in use, the legs step on the pedal 4 to drive the backrest 9 to move with the slide rail 3, and simultaneously realize the hand lifting assistance through the armrest 5, forming a "leg-based, hand and leg coordinated" force mode; the protective ring 6 moves synchronously with the backrest, and the protection radius is 500mm.

[0029] In this embodiment, the base 2 has a U-shaped structure. A first crossbar 21 is provided at the opening of the base 2. A second crossbar 22 is provided below the first crossbar 21. The support column 8 is connected to the end of the base 2 away from the opening. Specifically, the bottom width of the base 2 is 816 mm, which increases the ground contact area by 40%.

[0030] In a further embodiment, the load-bearing assembly 7 includes two load-bearing guide columns, one end of which is connected to the second crossbar 22, and the other end is connected to the top of the support column 8. Specifically, there are two support columns 8, the tops of the two support columns 8 are bent inward and connected to one end of the load-bearing guide column via a connecting plate 81, and the top of the second crossbar 22 extends upward to form a curved connecting column 24, which is connected to the other end of the load-bearing guide column.

[0031] In a further embodiment, the pedals 4 are mounted on the base 2 via a connecting bracket 23, which is tilted relative to the base 2. Specifically, the pedals 4 are made of PU with an anti-slip coefficient of 0.8. The pedals are designed with an appropriate width based on the foot characteristics of the elderly and have a certain inclination. This helps the elderly better understand the force exerted by their leg muscles during use, assisting them in exercising more effectively.

[0032] In a further embodiment, a lumbar pad 10 is provided on the backrest 9. Specifically, the lumbar pad can fit the lumbar curve, and its height is adjustable, specifically 190-280 mm.

[0033] The solution of this embodiment has the following advantages:

[0034] Safety: The setting of the protective ring 6 can achieve dynamic protection and reduce the risk of falling by 90% (laboratory simulation data); the setting of the waist pad 10 can reduce the probability of waist injury by 70%.

[0035] Age-suitability: The load-bearing guide column has an inclination angle of 45°, so that the inclination angle of the slide rail 3 during movement is also 45°, which can reduce the peak pressure of the knee joint by 35% (mechanical sensor test).

[0036] Training efficiency: The training components include armrests and pedals, which are used in conjunction to increase the activation efficiency of the lower limb muscles by 50% (EMG data) and simultaneously exercise the upper limb muscles.

[0037] Social benefits: It meets the lower limb training needs of 400 million elderly people and reduces community installation costs by 40% (compared with imported rehabilitation equipment).

[0038] In this embodiment, the refined counterweight 1 can meet the diverse exercise needs of elderly people with different physical fitness; the base 2 is U-shaped as a whole, which keeps the device stable and effectively prevents rollover, providing a safer fitness experience; the slide rail 3 is made of aluminum alloy to increase service life, improve the overall texture, and reduce wear on the slide rail; the pedal 4 supports the user's lower limbs, and the leg flexion and extension are achieved by stepping on the pedal, which drives the backrest 9 to move back and forth along the slide rail 3, thereby exercising the leg muscles and ensuring the stability of the overall structure during exercise; by setting the armrest 5, holding it tightly during use can not only tighten the core, but also maintain The body is stable and strain caused by excessive force is prevented. The arms can also be used to leverage strength to achieve a hand-to-leg exercise method. The protective ring 6 adopts a circular shape, which can protect the user to the greatest extent while retaining sufficient exercise space, protecting the user throughout the exercise. The setting of the load-bearing component 7 provides the slide rail 3 with a movement trajectory with a certain inclination angle, which can reduce the wear and tear on the user's knee joint during exercise, and at the same time help the elderly reduce their own weight load, so that they can exercise more easily. The support column 8, the base 2 and the load-bearing component 7 form a triangular structure, which mainly plays the role of bearing counterweights and maintaining overall stability.

[0039] According to ergonomics research, the height and width of the two armrests 5 should meet the user's comfort needs. The height and width of the armrests 5 should be designed based on users of different heights, weights, and genders. Based on the physiological dimensions of the elderly, the height of the armrests 5 should be set to 750-900mm and the width should be set to 500mm. Both the width and height of the armrests should be adjustable.

[0040] Working principle:

[0041] When exercising, the elderly step on the inclination pedals 4 with both feet, hold the armrests 5 on both sides with both hands, keep their waists close to the backrest 9 and the waist pad 10, and use the force of their legs to drive the backrest 9 to move obliquely upward along the slide rail 3, while simultaneously assisting with hand lifting. The resistance is adjusted by adding or removing dumbbell plates (1-5kg / plate), and the resistance can be adjusted by a certain amount of body weight or adding counterweights to achieve training.

[0042] The waist pad 10 provides a certain amount of support, which can also effectively prevent the elderly from injuring their waist due to excessive movement; the protective ring 6 connected to the backrest 9 can effectively prevent the elderly from falling during exercise and play a protective role throughout the exercise process; the effect of linked fitness is achieved by flexing and extending the legs and pulling the armrests with the hands, which improves the efficiency of leg muscle exercise for the elderly and plays a positive role in promoting the physical health development of the elderly and maintaining their mental health.

[0043] The overall structure of the fitness equipment is designed to make it easy for seniors to understand and use safely. A specific tilt angle is used to reduce damage to joints and other parts of the body. The seat and waist pads effectively prevent injuries caused by exerting force. The linkage structure designed for both hands and legs allows seniors to receive targeted leg training while also strengthening their upper limbs, achieving a coordinated fitness effect.

[0044] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
