Description

Technical Field

[0001] This utility model relates to a fitness equipment, and more particularly to a foldable support structure for a fitness equipment. Background Technology

[0002] With the fast pace of life, people's time is becoming increasingly fragmented, making it difficult to find time for outdoor exercise. To maintain a certain level of physical activity and ensure good health, most people choose to exercise at home or go to the gym. Common fitness equipment includes stationary bikes, treadmills, elliptical trainers, stair climbers, exercise bikes, or rowing machines. Fitness equipment is generally installed indoors, and to ensure the stability of the equipment during use, a bottom support is usually installed at the bottom.

[0003] For example, patent CN220307059U discloses a self-generating system for fitness equipment, which includes a base and a frame body. The frame body is set on the base, and the base is used to contact and support the ground. The frame body of traditional fitness equipment is generally designed to be foldable, while the base is generally fixed and cannot be folded. When folding for storage or packing, the width of the base when unfolded is relatively wide, so the fitness equipment still has a large size in the width direction after being folded due to the influence of the base, so the folded fitness equipment still needs to occupy a large area.

[0004] To address the issue of the base support legs not being foldable, fitness equipment with rotatable and foldable support legs has emerged on the market. For example, patent CN219879036U discloses a foldable exercise bike, which includes a bottom crossbeam and two support structures. The two support structures are respectively located at both ends of the bottom crossbeam and are arranged opposite each other. Each support structure includes a connector and two support legs. The connector is located at the end of the bottom crossbeam and has a reinforcing column. The two support legs are arranged opposite each other, and one end of each support leg is rotatably connected to the connector. The rotatable angle of the support legs is greater than 90° and less than 180°.

[0005] The existing support structure has the following problems: The two support legs of the support structure rotate independently. When folding or unfolding, the user needs to rotate and adjust one support leg first, and then rotate and adjust the other support leg after adjusting it. The adjustment efficiency is low. In addition, when the support legs are rotated and unfolded, the operator needs to judge the unfolding angle by his own feeling, which will cause a large deviation in the unfolding angle of the two sides, making the fitness equipment unstable at the bottom due to the imbalance between the two sides. Utility Model Content

[0006] Based on the fact that the two support legs of the above-mentioned support structure rotate independently, the user needs to rotate and adjust one support leg first when folding or unfolding, and then rotate and adjust the other support leg after adjusting it. The adjustment efficiency is low. In addition, when the support legs are rotated and unfolded, the operator needs to judge the unfolding angle by his own feeling, which will cause a large deviation in the unfolding angle of the two sides. This will cause the fitness equipment to be unstable at the bottom due to the imbalance of the two sides. This utility model provides a foldable support structure for fitness equipment.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a foldable support structure for fitness equipment is set on the main support of the fitness equipment, including two foot tubes for support and a locking mechanism. The two foot tubes are symmetrically arranged and both foot tubes are rotatably connected to the main support. One end of the two foot tubes is opposite to each other, and at least one arc-shaped tooth is provided on the opposite end of the two foot tubes. The teeth on the two foot tubes mesh, so that when one foot tube rotates, it drives the other foot tube to rotate synchronously to unfold or fold. The locking mechanism is used to lock the two foot tubes in the unfolded state.

[0008] A further preferred embodiment of this utility model is as follows: the locking mechanism includes a locking tongue that rotates around a fulcrum in the middle and a spring that applies elastic force to the locking tongue. One end of the teeth is provided with a straight edge for limiting the maximum rotation angle of the leg tubes. When the two leg tubes rotate and unfold synchronously to the position where the straight edges at one end of the two teeth abut each other, the two leg tubes are in an unfolded state. The head of the locking tongue simultaneously blocks one side of the opposite end of the two leg tubes to restrict the rotation and folding of the two leg tubes. Pressing the tail of the locking tongue causes the head of the locking tongue to lift up to release the locking of the two leg tubes, and the two leg tubes can rotate and fold synchronously.

[0009] A further preferred technical solution of this utility model is as follows: the foot tube includes a tube body, a rotating connecting part and an arc-shaped block. The rotating connecting part is used to rotately connect with the main support. The arc-shaped block and the tube body are connected to the outer wall of the rotating connecting part, and the arc-shaped block and the tube body are arranged in opposite directions. The toothed part and the straight edge part are arranged on the outer edge of the arc-shaped block. When the two foot tubes are in the unfolded state, the head of the locking tongue blocks the end of the arc-shaped block on both sides near the straight edge part.

[0010] A further preferred embodiment of this utility model is as follows: the locking mechanism includes a mounting base, the mounting base includes a lower locking seat and an upper locking seat, the lower locking seat and the upper locking seat are detachably connected, a mounting cavity is formed between the upper locking seat and the lower locking seat, the latch and the spring are both installed in the mounting cavity, the middle part of the latch can rotate relative to the mounting base around a fulcrum, the head and tail of the latch extend from both sides of the mounting base respectively, and the latch, the spring, the lower locking seat and the upper locking seat are combined into a whole.

[0011] A further preferred embodiment of this utility model is as follows: the middle part of the latch is provided with a downwardly extending support leg, and the lower end of the support leg is provided with a rotating shaft that rotatably cooperates with the mounting cavity. The rotating shaft serves as the fulcrum of the latch, and the latch rotates around the rotating shaft.

[0012] A further preferred technical solution of this utility model is as follows: the tail of the locking tongue is provided with a pressing plate, and the front end of the locking tongue is provided with a slot. The slot has a top surface and an inner side wall. When the two legs are rotated to the unfolded state, the spring drives the locking tongue to rotate so that the top surface of the slot is pressed against the upper part of the opposite end of the two legs, and the inner side wall of the slot simultaneously blocks one side of the opposite end of the two legs to lock the rotation of the two legs.

[0013] A further preferred technical solution of this utility model is that the two legs are in a figure-eight shape when unfolded.

[0014] A further preferred embodiment of this utility model is that the tube body is a square tube.

[0015] A further preferred embodiment of this utility model is as follows: the rotating connecting part is a cylinder, and the arc-shaped block and the tube are both fixedly connected to the outer circumferential surface of the cylinder.

[0016] A further preferred technical solution of this utility model is as follows: after the upper and lower locking seats are assembled, they are connected and fixed by screws. The locating protrusion is provided on the assembly surface of the upper locking seat. When the upper and lower locking seats are assembled, the locating protrusion is inserted into the lower locking seat for positioning.

[0017] Compared with the prior art, the advantages of this utility model are that both leg tubes are rotatably connected to the main support, with one end of each leg tube facing each other and at least one arc-shaped tooth on the facing end. The teeth on the two leg tubes mesh, so that when one leg tube rotates, it drives the other leg tube to rotate synchronously to unfold or fold. When adjusting, the user only needs to adjust one side of the leg tube, while the other side of the leg tube can be simultaneously unfolded or folded through the linkage between the teeth. The adjustment efficiency is high, and the consistency of the rotation of the two leg tubes can be maintained. This maintains the balance of the support of the two leg tubes on both sides of the fitness equipment in the unfolded state, thereby achieving a more stable support effect for the fitness equipment.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0032] Figures 1-8As shown, the foldable support structure of the fitness equipment is set on the main support frame 1 of the fitness equipment. It includes two support legs 2 and a locking mechanism 3. The two support legs 2 are symmetrically arranged and can be rotatably connected to the main support frame 1. One end of the two support legs 2 is opposite to each other. At least one arc-shaped tooth 11 is provided on the opposite end of the two support legs 2. The teeth 11 on the two support legs 2 mesh with each other, so that when one support leg 2 rotates, the other support leg 2 is driven to rotate synchronously to unfold or fold through the cooperation between the teeth 11. The locking mechanism 3 is used to lock the two support legs 2 in the unfolded state.

[0033] In this patent, the user only needs to adjust one side of the leg tube 2 during adjustment, while the other side of the leg tube 2 can be folded or unfolded synchronously through the linkage between the teeth 11. The adjustment efficiency is high. The two leg tubes 2 can be unfolded to support the ground when the fitness equipment is in use, and the two leg tubes 2 can also be folded to reduce the overall volume of the fitness equipment when it is not in use. The linkage between the two leg tubes 2 through the teeth 11 can maintain the consistency of the rotation of the two leg tubes 2, and maintain the balance of the support of the two leg tubes 2 on both sides of the fitness equipment in the unfolded state, thereby achieving a more stable support effect for the fitness equipment.

[0034] Figures 2-4 As shown, preferably, when unfolded, the two leg tubes 2 are arranged in a V-shape, which can provide more stable support for the fitness equipment.

[0035] Figure 4 , Figure 10 As shown, one end of the toothed part 11 is provided with a straight edge 15 for limiting the maximum rotation angle of the leg tube 2. When the two leg tubes 2 rotate and unfold synchronously to the position where the straight edges 15 at one end of the two toothed parts 11 abut, the two leg tubes 2 are in the unfolded state. For example, when the right leg tube 2 is rotated and unfolded from the folded position in the counterclockwise direction, during the rotation of the right leg tube 2, the toothed part 11 at the end of the right leg tube 2 cooperates with the toothed part 11 at the end of the left leg tube 2 to drive the left leg tube 2 to rotate and unfold from the folded position in the clockwise direction until the straight edge 15 at the end of the right leg tube 2 abuts with the straight edge 15 at the end of the left leg tube 2. The two straight edges 15 abut against and limit the right leg tube 2 from continuing to rotate in the counterclockwise direction. At this time, the two leg tubes 2 are in the unfolded state in a figure-eight shape.

[0036] Figure 4 , Figure 5 , Figure 8As shown, the locking mechanism 3 includes a locking tongue 25 that rotates around a fulcrum in the middle and a spring 21 that applies elastic force to the locking tongue 25. When the left and right legs 2 rotate to the unfolded state, the head 12 of the locking tongue 25 simultaneously blocks one side of the opposite end of the two legs 2, restricting the two legs 2 from rotating and folding, thereby locking the two legs 2 in the unfolded state. Pressing the tail of the locking tongue 25 causes the head 12 of the locking tongue 25, which is blocking one side of the opposite end of the two legs 2, to lift up and release the lock on the two legs 2. At this time, the two legs 2 can be driven by external force to rotate and fold. This structural arrangement allows the locking tongue 25 to rotate driven by the spring 21 when the two legs 2 rotate from the folded state to the unfolded state, causing the head 12 to automatically move down and lock one side of the opposite end of the two legs 2, forming a lock. The press-to-unlock method is convenient for user operation.

[0037] Figure 8 As shown, the locking mechanism 3 includes a mounting base 5, which includes a lower locking seat 23 and an upper locking seat 19. The lower locking seat 23 and the upper locking seat 19 are detachably connected, and a mounting cavity 18 is formed between the upper locking seat 19 and the lower locking seat 23. The locking tongue 25 and the spring 21 are both installed in the mounting cavity 18. The middle part of the locking tongue 25 can rotate relative to the mounting base 5 around a fulcrum. The head 12 and tail of the locking tongue 25 extend from both sides of the mounting base 5, respectively. The locking tongue 25, the spring 21, the lower locking seat 23 and the upper locking seat 19 are combined into a whole. This structure allows the locking mechanism 3 to be pre-assembled. First, the locking tongue 25, the spring 21, the upper locking seat 19 and the lower locking seat 23 are combined into a whole, and then the whole is installed on the main support 1, so that the locking tongue 25 locks the two foot tubes 2. The assembly is convenient.

[0038] Preferably, the upper locking seat 19 and the lower locking seat 23 are connected and fixed by screws after being assembled. The locating protrusion 22 is provided on the assembly surface of the upper locking seat 19. When the upper locking seat 19 and the lower locking seat 23 are assembled, the locating protrusion 22 is inserted into the lower locking seat 23 for positioning, which facilitates the installation of the upper locking seat 19 and the lower locking seat 23.

[0039] The upper locking seat 19 is provided with an upper groove 20, and the lower locking seat 23 is provided with a lower groove 24 opposite to the upper groove 20. The upper groove 20 passes through the front and rear sides of the upper locking seat 19, and the lower groove 24 passes through the front and rear sides of the lower locking seat 23. When the upper locking seat 19 and the lower locking seat 23 are assembled, the upper groove 20 and the lower groove 24 combine to form the aforementioned mounting cavity 18. The front and rear sides of the mounting seat 5 form two openings of the mounting cavity 18, and the head 12 and tail of the locking tongue 25 extend out from the two openings respectively.

[0040] The middle part of the latch 25 is provided with a downwardly extending support leg 26. The lower end of the support leg 26 is provided with a rotating shaft 27 that rotates with the mounting cavity 18. The rotating shaft 27 serves as the fulcrum of the latch 25, and the latch 25 rotates around the rotating shaft 27.

[0041] Preferably, a rotating connecting groove that mates with the rotating shaft 27 can be provided at the bottom of the mounting cavity 18. The rotating shaft 27 is rotatably accommodated in the rotating connecting groove. One end of the spring 21 abuts against the mounting base 5, and the other end of the spring 21 presses against the top of the latch 25, applying a spring force to the latch 25 to rotate and reset it. That is, the spring force acts on the latch 25, causing the head 12 of the latch 25 to tend to move downward. In addition, the downward pressing of the spring 21 on the latch 25 can also limit the overall movement of the latch 25 up and down in the mounting cavity 18.

[0042] Figure 9 As shown, preferably, the tail of the latch 25 is provided with a pressing plate 6, and the tail of the latch 25 extends out of the mounting base 5 for the user to press to unlock. The front end of the head 12 of the latch 25 is provided with a slot 16, which has a top surface 28 and an inner side wall 17. When the two legs 2 are rotated to the unfolded state, the spring 21 drives the latch 25 to rotate, causing the head 12 of the latch 25 to move down. During the downward movement of the head 12 of the latch 25, the opposite ends of the two legs 2 enter the slot 16, and the latch 25 locks the rotation of the two legs 2. At this time, the top surface 28 of the latch 25 is pressed down against the opposite ends of the two legs 2 by the action of the spring 21, and the inner side wall 17 of the slot 16 blocks one side of the opposite ends of the two legs 2.

[0043] Preferably, the foot tube 2 includes a tube body 7, a rotating connecting part 8, and an arc-shaped block 10. The rotating connecting part 8 is used to rotatably connect with the main support 1. The arc-shaped block 10 and the tube body 7 are connected to the outer side wall of the rotating connecting part 8, and the arc-shaped block 10 and the tube body 7 are arranged in opposite directions. The aforementioned toothed part 11 and straight edge part 15 are provided on the outer edge of the arc-shaped block 10. When the two foot tubes 2 are in the unfolded state, the head 12 of the locking tongue 25 blocks the ends of the arc-shaped blocks 10 on both sides near the straight edge part 15.

[0044] The arc-shaped block 10 is a sheet structure, and the center of the arc-shaped block 10 coincides with the rotation center of the locking tongue 25.

[0045] The tube body 7 is a square tube. Square tubes have good support strength and stability. Support blocks 4 can be fixed at the bottom of the square tube to contact the ground.

[0046] The rotating connection part 8 is a cylinder. The arc block 10 and the tube 7 are both fixedly connected to the outer circumference of the cylinder. The cylinder has a connection hole 9 at the center, which is rotatably connected to the support body through the connection hole 9.

[0047] Figures 3-7As shown, the working principle is as follows: One end of the arc-shaped block 10 near the straight edge 15 is designated as the first end 14, and the other end as the second end 13. When the two legs 2 are fully retracted, they are parallel or nearly parallel. The second ends 13 of the arc-shaped blocks 10 on both sides are connected, and the two legs 2 are retracted to the bottom of the main support 1. At this time, the head 12 of the latch 25 is raised, and the spring 21 is compressed. The elastic force of the spring 21 acts on the latch 25, causing the head 12 of the latch 25 to press downwards onto the arc-shaped block. On the top of block 10, when it is necessary to support the main support 1 via the leg tube 2, one side of the leg tube 2 is bent outward, causing the leg tube 2 to rotate out from under the main support body. During the rotation of one side of the leg tube 2, the other side of the leg tube 2 unfolds simultaneously. The leg tube 2 is driven by external force to rotate to the position where the straight edges 15 on the outer edges of the two arc blocks 10 abut each other, so that the arc blocks 10 at the ends of the two leg tubes 2 become the first ends 14 connected. At this time, the leg tube 2 is fully unfolded and in the unfolded state. When it rotates to the fully unfolded position, the two arc blocks 10 The first end 14 of the latch 25 is aligned with the slot 16 on the head 12 of the latch 25, causing the area below the head 12 of the latch 25 to fall. The spring 21 drives the latch 25 to rotate, causing the head 12 of the latch 25 to fall. During the fall of the head 12 of the latch 25, the first end 14 of the two arc-shaped blocks 10 enters the slot 16, causing the top surface 28 of the slot 16 to press down on the top of the two arc-shaped blocks 10. At this time, the inner wall 17 of the slot 16 simultaneously blocks one side of the first end 14 of the arc-shaped blocks 10 on both sides, restricting the rotation and folding of the legs 2 on both sides. This fixes the two legs 2 in a fixed state. When the legs 2 need to be folded again after use, first press down on the pressing plate 6 at the tail of the locking tongue 25 and do not release it, so that the head 12 of the locking tongue 25 is raised. The head 12 of the locking tongue 25 is raised, so that the inner wall 17 of the slot 16 moves upward from the side of the first end 14 where the two arc blocks 10 meet, thus releasing the lock on the two legs 2. When the legs 2 are rotated to any angle, the hand pressing the pressing plate 6 can be released. At this time, the head 12 of the locking tongue 25 presses on the top of the arc block 10 without affecting the rotation of the arc block 10.

[0048] The locking mechanism 3 described above can also be implemented using other structures, and is not limited to the methods described above, for example:

[0049] The first option involves setting a retractable locking pin on the main support 1, and setting a corresponding locking hole on the arc-shaped block 10 on one side. When the two legs 2 are rotated to the unfolded state, the locking pin is opposite to the locking hole, and the locking pin pops out and locks into the locking hole to stop the rotation of the two legs 2. When it is necessary to fold the legs 2 back, the locking pin is pushed up to disengage from the locking hole and complete the unlocking.

[0050] In another embodiment, the arc-shaped blocks 10 on both sides are spaced apart from the ground. The arc-shaped blocks 10 are provided with threaded holes that pass through the upper and lower sides. Hexagonal bolts are screwed into the threaded holes. When the hexagonal bolts rotate relative to the arc-shaped blocks 10, they can move up and down along the bolts in the threaded holes. The main support 1 is provided with locking holes corresponding to the hexagonal bolts. When the leg tubes 2 on both sides are rotated to the unfolded state, the locking holes are opposite to the hexagonal bolts. The hexagonal bolts are rotated by the wrench on the plate to move the hexagonal bolts up and insert them into the locking holes, thereby locking the rotation of the two leg tubes 2. When it is necessary to fold the leg tubes 2 back, the hexagonal bolts are rotated in the opposite direction by the wrench on the plate to move the hexagonal bolts down and disengage them from the locking holes.

[0051] The foldable support structure for the fitness equipment provided by this utility model has been described above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
