Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a multifunctional fitness equipment. Background Technology

[0002] Fitness equipment is a type of equipment used to assist users in exercising. Common fitness equipment includes treadmills, stair climbers, and waist trimmers.

[0003] Existing fitness equipment has limited functionality, only enabling single-function fitness exercises and failing to meet the diverse fitness needs of users. Utility Model Content

[0004] This utility model provides a multifunctional fitness equipment, which aims to solve the problem of the single function of existing fitness equipment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A multifunctional fitness equipment includes a sliding support and a handrail assembly. One end of the sliding support is disposed on the handrail assembly. The sliding support is provided with a mounting base for mounting the pedal. The mounting base is slidably connected to the sliding support. The mounting base is provided with a pedal. The pedal is detachably connected to the mounting base. The mounting base is provided with a knee support.

[0007] The multi-functional fitness equipment includes a stair-climbing mode and a waist-slimming mode;

[0008] In the stair-climbing mode, the step is mounted on the sliding bracket;

[0009] In the waist-slimming mode, the pedal is removed.

[0010] Further improvement: The multi-functional fitness equipment also includes a walking mode;

[0011] In the walking mode, the pedal is mounted on the mounting base, and the angle between the sliding bracket and the ground is within a first angle range;

[0012] In the stair-climbing mode, the step is mounted on the mounting base, and the angle between the sliding bracket and the ground is within a second angle range, wherein the minimum angle of the second angle range is not less than the maximum angle of the first angle range.

[0013] Based on the above technical solution, the walking mode further enhances the functionality of multi-functional fitness equipment. In walking mode, the angle between the sliding support and the ground is within a first angle range. This relatively small angle design simulates the environment of walking on flat ground. When the angle is small, the pedals experience less undulation during movement, more closely resembling the vertical movement of the feet when walking on real flat ground. At this time, the user's leg muscles exert force similar to walking on flat ground, primarily with the soleus and gastrocnemius muscles on the back of the calf playing a role in the push-off and lift of the foot. Simultaneously, the quadriceps femoris on the front of the thigh and the hamstrings on the back also moderately participate to maintain leg stability and movement rhythm. This exercise mode places relatively less pressure on the joints, making it suitable for beginners, the elderly, or those in rehabilitation for low-intensity aerobic exercise. It helps improve cardiopulmonary function, enhance leg muscle strength and endurance, and reduce the risk of sports injuries. Because the walking mode simulates the movements of daily walking, it can comprehensively exercise all muscle groups in the legs. During exercise, the ankle joint needs to perform small-amplitude flexion, extension, and inversion / extension movements, which can exercise the muscles and ligaments around the ankle, improving its flexibility and stability. Simultaneously, the gluteal muscles also participate to some extent, especially during the push-off phase of walking, where the gluteus maximus propels the body forward, thus receiving a workout. Consistently practicing this walking pattern can make the leg and gluteal muscles firmer and more defined.

[0014] A further improvement: In the waist-shaping mode, the pedal is removed to expose the knee support to the outside.

[0015] Based on the above technical solution: After removing the pedals and exposing the knee support, users can place their knees on the knee support in waist-shaping mode. This design allows the body to focus more on the rotation and twisting of the waist during exercise. Users can use their waist strength to rotate their upper body left and right, similar to belly dancing or performing specific waist exercises. At this time, the knee support provides stable support for the knees, limiting unnecessary leg movement and allowing users to more precisely concentrate their strength on the waist, thus more effectively exercising the waist muscles, including the rectus abdominis, external oblique, internal oblique, and psoas major. Through continuous rotation and twisting movements, the strength and flexibility of the waist muscles can be enhanced, improving the waist's mobility. The exposure of the knee support provides users with a clear postural reference point. During exercise, users will naturally place their knees on the support, thus helping the body maintain a relatively stable and correct posture. This correct posture helps reduce the risk of lower back injury caused by improper posture during exercise.

[0016] A further improved solution: one end of the sliding bracket is slidably connected to the handrail assembly, and a locking component is provided between the sliding bracket and the handrail assembly to lock the sliding bracket onto the handrail assembly. The locking component adjusts the angle of the sliding bracket relative to the ground by locking the sliding bracket onto the handrail assembly at different positions.

[0017] In the walking mode, the pedal is mounted on the mounting base, and the sliding bracket is locked to the handrail assembly using the locking assembly, with the angle between the sliding bracket and the ground within a first angle range;

[0018] In the stair-climbing mode, the step is installed on the mounting base, and the sliding bracket is locked to the handrail assembly using the locking assembly. The angle between the sliding bracket and the ground is within a second angle range, and the maximum angle of the second angle range is not less than the maximum angle of the first angle range.

[0019] In the waist-slimming mode, the pedal is removed, and the sliding bracket is locked to the armrest assembly using the locking assembly.

[0020] Based on the above technical solution, through the sliding connection between the sliding bracket and the handrail assembly, and the setting of the locking component, users can easily switch between walking mode, stair climbing mode, and waist-shaping mode. When a user wants to switch from walking mode to stair climbing mode, they only need to loosen the locking component, adjust the position of the sliding bracket on the handrail assembly to achieve a suitable angle range for stair climbing mode, and then lock the locking component. The entire process does not require complicated operations or additional tools, greatly saving time and energy and improving fitness efficiency. This convenient mode switching function allows users to flexibly choose different exercise modes according to their physical condition, exercise goals, and time arrangements, realizing personalized fitness plans. In different scenarios, users' needs for fitness equipment also vary. In a home environment, space may be relatively limited, and users may want to complete multiple exercises on one piece of equipment. The design of this multi-functional fitness equipment perfectly meets this need, allowing users to easily switch between different exercise modes in a limited space for comprehensive physical exercise. In public places such as gyms, this multi-functional design can also improve the utilization rate of equipment, meet the diverse fitness needs of different members, and reduce the equipment's footprint and purchase cost. The locking mechanism secures the sliding support to different positions on the handrail assembly, allowing for precise adjustment of the angle between the sliding support and the ground. In walking mode, the angle can be adjusted to a first range to simulate walking on flat ground; in stair climbing mode, it can be adjusted to a second range to simulate climbing stairs; and in waist-slimming mode, the angle can be adjusted to suit the user's needs. This precise angle adjustment enables each exercise mode to more realistically simulate the corresponding exercise scenario, providing users with a more scientific and effective workout.

[0021] A further improved solution: one end of the pedal is rotatably connected to the mounting base, and the other end of the pedal is fixed to the mounting base via an angle adjuster.

[0022] Based on the above technical solution: one end of the pedal is rotatably connected to the mounting base, while the other end is fixed via an angle adjuster. This design allows the pedal angle to be flexibly adjusted. When simulating walking on flat ground, the pedal angle can be adjusted to a near-horizontal position, allowing the user to experience a similar force exertion and rhythm as walking on flat ground. For rehabilitation patients or those wanting to engage in light aerobic exercise, this gentle angle allows them to comfortably complete the exercise, reducing joint stress. When simulating uphill exercise, the angle between the pedal and the mounting base is increased via the angle adjuster, raising the front end of the pedal. At this time, the user needs to overcome greater gravitational force, resulting in stronger stimulation of the leg muscles, especially the quadriceps and gluteal muscles, just like walking uphill, effectively enhancing leg strength and endurance.

[0023] A further improved solution: The angle adjuster includes a pin, the mounting base is provided with a first pin hole that mates with the pin, the pedal is provided with a second pin hole that mates with the pin, there are multiple second pin holes, and the pin adjusts the angle of the pedal by mates with different second pin holes;

[0024] The pedal is rotatably connected to the mounting base via a pin. In the waist-shaping mode, the pedal can be removed by removing the pin and the pin.

[0025] Based on the above technical solution: a first pin hole is provided on the mounting base, and multiple second pin holes are provided on the pedal. A pin engages with these pin holes to adjust the pedal angle. Multiple second pin holes allow for various combinations, enabling users to precisely adjust the pedal to the appropriate angle according to their needs. For low-intensity rehabilitation training, a smaller angle can be selected by inserting the pin into the corresponding second pin hole closer to the horizontal position; while for high-intensity leg strength training, a larger angle can be selected by inserting the pin into the higher second pin hole, thus meeting the diverse requirements of different exercise scenarios and training goals for pedal angle. This pin-type angle adjuster is very simple to operate. Users simply pull out the pin, rotate the pedal to the desired angle corresponding to the second pin hole, and then insert the pin to complete the angle adjustment. The entire process requires no complex tools or professional technical knowledge, and even first-time users can quickly get started. During exercise, if a user wants to change the intensity, they only need to spend a few seconds adjusting the pedal angle without interrupting the continuity of the exercise, improving convenience and efficiency. The engagement of the pin with the first and second pin holes forms a stable connection. Once the pin is inserted into the pin hole, it effectively restricts the rotation of the pedal relative to the mounting base, ensuring that the pedal does not wobble or change angle during exercise. During rapid pedaling, the stable connection ensures the pedal remains at the set angle, preventing falls or injuries caused by a loose pedal and providing a safe and reliable exercise environment. The pedal is rotatably connected to the mounting base via a pin, a design that ensures structural stability while also providing a degree of flexibility. The pin, as the center of rotation, allows for smooth angle adjustment of the pedal. During angle adjustment, the pedal can rotate freely around the pin, reducing resistance and allowing users to easily change the pedal angle. Furthermore, this rotatable connection can withstand a certain load, ensuring that the connection between the pedal and the mounting base will not be damaged by stress during exercise.

[0026] A further improved solution: There are two mounting seats, left and right, and both mounting seats are slidably connected to the sliding bracket. The pedal corresponds to each mounting seat, and the knee support corresponds to each mounting seat. An elastic rope is provided between the two mounting seats, and a first guide wheel is provided on each of the two mounting seats. The two ends of the elastic rope pass around the first guide wheel and are fixed to the mounting seat.

[0027] A pull rope is also provided between the two mounting seats on the left and right. The upper end of the sliding bracket is provided with two second guide wheels for guiding the pull rope. The pull rope passes around the second guide wheels and is fixed to the mounting seat. There are two second guide wheels.

[0028] Based on the above technical solution, the sliding function of the mounting base enables diverse exercise modes. These modes can be used in various exercise scenarios, such as simulated running, mountain climbing, or rehabilitation training. In simulated mountain climbing, the greater stride and strength required by the legs during uphill movement can be simulated, enhancing the training effect on leg muscles. In rehabilitation training, gentler, low-intensity exercises can be performed to help patients gradually recover their physical functions. An elastic cord is installed between the two mounting bases, with its ends looping around the first guide wheel and fixed to the mounting base. When the user exercises, such as stepping on the pedal or moving their body, the mounting base slides relative to each other, stretching the elastic cord and generating resistance. This resistance increases the difficulty of the exercise, requiring the user's muscles to overcome greater force to complete the movement, thus more effectively training the muscles in the legs, buttocks, and other areas, improving muscle strength and endurance.

[0029] A further improved solution: A connecting rod is provided between the left and right mounting seats to keep the left and right mounting seats moving synchronously. The two ends of the connecting rod are respectively fixed to the left and right mounting seats by detachable connection. In the waist-shaping mode, the pedal is removed by removing the pin and the pin shaft, and the connecting rod is fixed to the left and right mounting seats.

[0030] Based on the above technical solution: the two ends of the connecting rod are detachably fixed to the left and right mounting seats, allowing the left and right mounting seats to move synchronously during exercise. The synchronously moving mounting seats provide more stable support for the entire exercise device. During exercise, the connecting rod plays a connecting and stabilizing role, reducing relative swaying between the mounting seats. Because the connecting rod ensures the synchronous movement of the mounting seats, in waist-shaping mode, users do not need to control the left and right mounting seats separately; they only need to focus on the overall movement. This simplifies the exercise control process, reduces the difficulty of exercise, and makes it easier for beginners or those with weaker athletic abilities to grasp the key points of the exercise, increasing its feasibility and participation.

[0031] A further improvement: The pedal is also equipped with a foot pad, which is fixed to the pedal by screws.

[0032] Based on the above technical solution: Foot pads are generally made of materials with a high coefficient of friction, such as rubber. When the foot pad is fixed to the pedal with screws, the friction between the foot and the foot pad increases significantly when the user steps on the pedal, preventing the foot from slipping.

[0033] A further improved solution: The locking assembly includes a slide block mounted on the sliding bracket, the slide block having a sliding hole that mates with the handrail assembly, the handrail assembly having a first locking hole (multiple first locking holes), the slide block having a second locking hole, and the locking assembly further including a locking shaft that mates with the first locking hole and the second locking hole, the angle of the sliding bracket being adjusted by having the locking shaft mate with different first locking holes.

[0034] Based on the above technical solution: the armrest assembly has multiple first locking holes, and the slide block has second locking holes. By engaging different first locking holes with the locking shaft, multiple precise adjustments to the angle of the sliding bracket can be achieved. The multiple first locking holes act like multiple precise adjustment scales. Users can insert the locking shaft into different first locking holes according to their needs, thereby adjusting the sliding bracket to the most suitable angle, greatly improving the personalization of use. This adjustment method is simple to operate; simply pull out the locking shaft and insert it into another suitable locking hole to complete the angle adjustment. Compared to some complex adjustment mechanisms, such as designs that require tools to tighten screws or adjust multiple components to change the angle, the adjustment process of this locking assembly is much faster and more convenient.

[0035] A further improved solution: The slide is provided with a connecting seat, and the sliding bracket is provided with a connecting body, which is mounted on the connecting seat via a connecting shaft.

[0036] Based on the above technical solution: when the sliding bracket is subjected to external force, the connecting shaft can play a role in dispersing stress. It evenly transmits the external force to the connecting seat and the connecting body, avoiding excessive stress concentration at a certain local location.

[0037] A further improved solution: The connector includes two connecting pieces, forming a connecting cavity between them. A portion of the connector is located within the connecting cavity. Both the connector and the connecting pieces are provided with connecting holes that mate with the connecting shaft. There are multiple connecting holes on the connecting pieces. The angle between the connector and the connector is adjusted by mates of the connecting shaft with different connecting holes on the connecting pieces.

[0038] Based on the above technical solution: the connecting plate is equipped with multiple connecting holes that mate with the connecting shaft, allowing for precise adjustment of the angle between the connecting body and the connecting seat in multiple positions. This adjustment method is simple to operate; simply pull out the connecting shaft and insert it into another suitable connecting hole to adjust the angle between the connecting body and the connecting seat. When angle adjustment is needed during movement, no complicated procedures or tools are required; angle switching can be completed quickly without interrupting the movement rhythm due to excessive adjustment time, ensuring the continuity and smoothness of the movement.

[0039] A further improved solution: The armrest assembly is provided with an elbow support, the elbow support includes two support rollers, the armrest assembly is located between the two support rollers, and the knee support includes two roller bodies, with a cavity for accommodating the knee formed between the two roller bodies.

[0040] Based on the above technical solution: the elbow support has two support rollers with the armrest assembly located between them, and the knee support consists of two rollers forming a concave cavity to accommodate the knee. In the waist-slimming mode, this structure achieves a precise fit when the user places their elbow and knee on the corresponding support. Taking the elbow as an example, the two support rollers provide support from both sides, adapting well to the curvature of the elbow joint and avoiding discomfort caused by uneven support, allowing the user to relax more during exercise and improving overall comfort. The design of two support rollers and two roller bodies evenly distributes the pressure applied to the elbow and knee. During waist-slimming exercises, the body constantly changes posture, and the elbow and knee, as important support points, bear significant pressure. Without a reasonable pressure distribution structure, excessive local pressure may cause pain or even injury. This support design ensures that the pressure is evenly distributed on the support rollers and roller bodies, reducing the burden on specific areas of the body.

[0041] A further improved solution: The handrail assembly includes an inner rod and an outer rod. The inner rod is inserted into the outer rod. A pin is provided between the inner rod and the outer rod to lock the position of the inner rod relative to the outer rod. Both the inner rod and the outer rod are provided with mating holes that cooperate with the pin. The overall length of the handrail assembly can be adjusted by adjusting the position of the inner rod relative to the outer rod.

[0042] Based on the above technical solution: the inner rod is inserted into the outer rod, and both are equipped with mating holes for engaging with the pin. This provides multiple adjustment options for the length of the handrail assembly. Users can insert the pin into different mating holes according to their needs to achieve fine adjustment of the handrail assembly length. During exercise, people of different heights have different comfort requirements for handrail height. Taller people may need to lengthen the handrail assembly for more suitable support, while shorter people are more suited to a shorter handrail length. The multiple mating holes can meet the personalized needs of people of different heights, allowing everyone to find the most suitable handrail length. This adjustment method is very simple to operate. When a user wants to change the length of the handrail assembly, they only need to pull out the pin, move the inner rod relative to the outer rod to the appropriate position, and then insert the pin into the corresponding mating hole to complete the adjustment. The whole process does not require complicated tools or cumbersome steps and can be completed in a short time. For example, if a user feels that the current handrail length is not suitable during exercise and wants to adjust it, the operation can be completed quickly without affecting the continuity of exercise and the experience due to excessive adjustment time.

[0043] The beneficial effects of this utility model are as follows:

[0044] This invention allows for switching between stair-climbing and waist-slimming modes through the disassembly and installation of pedals. One piece of equipment can meet two different fitness needs, greatly enhancing its usability. This multi-functional fitness equipment only occupies the space of a single piece of equipment, offering a significant advantage for spaces with limited availability, such as homes or small gyms.

[0045] In stair-climbing mode, the up-and-down movement of the pedals simulates the action of climbing stairs. During this process, the quadriceps muscles on the front of the thighs continuously exert force to lift the legs, just like overcoming gravity to step upwards when actually climbing stairs. The hamstrings on the back of the thighs control speed and stabilize the joints during the leg descent, preventing injury from falling too quickly. The calf muscles are also fully exercised with each push-off and lift of the foot, enhancing calf strength and endurance. Simultaneously, the up-and-down movement engages the core muscles of the abdomen and back, which need to maintain stability and balance, just like maintaining posture during real stair climbing. Long-term training in stair-climbing mode can develop leg muscles, resulting in more defined lines, while also improving core strength and stability.

[0046] After removing the pedals in waist-slimming mode, the user kneels on the knee supports, causing them to slide synchronously along the sliding bracket. This exercise specifically targets and strengthens the waist muscles, enhancing flexibility and agility, reducing fat accumulation in the waist area, and sculpting a slender waistline.
