Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a foldable support leg for use in exercise bikes. Background Technology

[0002] As living standards continue to improve, people are paying more and more attention to physical exercise. Therefore, they use various types of exercise to achieve fitness goals. Among these, exercise bikes are commonly used fitness equipment, and with the rapid development of the exercise bike market, the types of exercise bikes have gradually become more diverse. Since exercise bikes are indoor fitness equipment, considering storage space, more and more people are choosing to use folding exercise bikes. After exercising, the exercise bike can be folded and stored away, reducing the space it occupies.

[0003] For exercise bikes, the support legs have the biggest impact on their size, so folding them up for storage is the best option. However, the entire bike and the user have relatively strict requirements for the support legs' load-bearing capacity and extremely high safety standards. Therefore, the stability of the locking structure when the support legs are unfolded and the ease of unlocking when storing them both need to be carefully considered in the design, ensuring safety while improving the user experience. Utility Model Content

[0004] This invention provides a foldable support leg for exercise bikes, which achieves both safety and convenient folding and storage. The specific technical solution is as follows:

[0005] A foldable support leg for an exercise bike includes multiple leg assemblies. Multiple pivots are fixedly connected to the bottom of the exercise bike body. Each leg assembly is hinged to one pivot at the bottom of the exercise bike body. The leg assembly can rotate relative to the exercise bike body to switch between a folded state and an unfolded state. A limiting sheet metal is fixedly provided on the pivot. A pivot pin is inserted into the leg assembly near the pivot. The end of the pivot pin corresponds to the limiting sheet metal. Rotating the pivot pin can cause the end of the pivot pin to engage with or slide against the limiting sheet metal to lock or unlock the leg assembly in the unfolded state.

[0006] Furthermore, the limiting sheet metal is provided with a sliding cross-section coaxial with the axis of rotation. The two ends of the sliding cross-section are connected to the storage groove and the unfolding groove. When the support leg assembly is in the storage state, the end of the pivot pin is inserted into the storage groove; when the support leg assembly is in the unfolding state, the end of the pivot pin is inserted into the unfolding groove. The end of the pivot pin is provided with a pivot pin cross-section and a locking arc surface. Rotating the pivot pin can switch the pivot pin between the locked state and the unlocked state. When it is locked, the locking arc surface is engaged with the sliding cross-section; when it is unlocked, the pivot pin cross-section can slide relative to the sliding cross-section.

[0007] Furthermore, the pivot pin is connected to an elastic component, which provides a force to rotate the pivot pin toward the locked state.

[0008] Furthermore, when the support leg assembly rotates from the retracted state to the unfolded state, the end of the sliding face near the retracted slot can abut against the face of the pivot pin and drive the pivot pin to rotate to the unlocked state.

[0009] Furthermore, a fixing post is fixedly installed below the pivot cover, and the elastic component is a torsion spring. The torsion spring is sleeved on the pivot, with one end of the torsion spring abutting against the fixing post and the other end fixed to the support leg assembly. The torsion spring can continuously provide the pivot with a force to rotate in the direction of locking the support leg assembly.

[0010] Furthermore, the two ends of the limiting sheet metal are symmetrically provided with sliding surfaces, storage grooves and unfolding grooves, and the limiting sheet metal can be connected to two rotating shafts.

[0011] Furthermore, the pivot includes a pivot cover, which is positioned above the support leg assembly and has locking and unlocking markings.

[0012] Furthermore, the outrigger assembly includes an outrigger main beam, with a pivot sleeve and a pivot pin sleeve connected to the end of the outrigger main beam. The pivot sleeve is connected to the pivot shaft, and the pivot pin is inserted into the pivot pin sleeve. The lower end is secured by a snap ring.

[0013] Furthermore, a fixing post is fixedly installed below the pivot pin cover, and a limiting groove is provided on the main beam of the support leg near the pivot pin sleeve. The end of the fixing post below the pivot pin is inserted into the limiting groove to limit the rotation angle of the pivot pin.

[0014] Furthermore, the outrigger assembly includes an outrigger cover, which is fitted onto the outside of the outrigger main beam.

[0015] This utility model has a simple structure and ingenious design. Through the cooperation of the limiting sheet metal and the pivot pin, the support leg assembly can be rotated within a certain range and limited at a specific angle, so that the support leg assembly can be completely stored under the office exercise bike, greatly reducing the space occupied and facilitating the packaging and transportation of the equipment. Furthermore, the support strength can be ensured when the support leg assembly is unfolded. In addition, by setting the pivot pin cover, it is convenient for users to unlock the support leg assembly, reducing the difficulty of operation and improving the user experience.

[0031] To better understand the purpose, function, and specific design of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of the foldable support leg of this utility model applied to an exercise bike.

[0032] like Figure 1-13 As shown, the foldable support leg of this utility model for exercise bikes includes multiple support leg components 1. Multiple pivots 2 are fixedly connected around the bottom of the exercise bike body. Each support leg component 1 is hinged to a pivot 2 at the bottom of the exercise bike body. The support leg component 1 can rotate relative to the exercise bike body to switch between a folded state and an unfolded state. A limiting sheet metal 3 is fixedly provided on the pivot 2. A pivot pin 4 is inserted into the support leg component 1 near the pivot 2. The end of the pivot pin 4 corresponds to the limiting sheet metal 3. Rotating the pivot pin 4 can make the end of the pivot pin 4 engage with or slide with the limiting sheet metal 3 to lock or unlock the support leg component 1 in the unfolded state.

[0033] Specifically, such as Figure 5 As shown, the limiting sheet metal 3 is provided with a sliding cross-section 31 coaxial with the axis of the rotating shaft 2. The two ends of the sliding cross-section 31 are connected to the storage groove 32 and the unfolding groove 31. When the support leg assembly 1 is in the storage state, the support leg assembly 1 is hidden and stored in parallel under the body of the exercise bike. At this time, the end of the pivot pin 4 is inserted into the storage groove 32. When the support leg assembly 1 is in the unfolding state, the support leg assembly 1 extends away from the body of the exercise bike and two adjacent support leg assemblies 1 form an angle to play a role in stable support. At this time, the end of the pivot pin 4 is inserted into the unfolding groove 31.

[0034] The end of the pivot pin 4 is provided with a snap-fit ​​arc surface 41 and a pivot pin tangential surface 42. Rotating the pivot pin 4 allows it to switch between a locked state and an unlocked state; for example Figure 8 As shown, when in the locked position, the engaging arc surface 41 corresponds to the sliding surface 31. When the support leg assembly 1 rotates relative to the exercise bike body, the engaging arc surface 41 engages with the sliding surface 31, thus preventing the support leg assembly 1 from rotating relative to the exercise bike body and thus allowing it to be stored. Figure 9 As shown, when in the unlocked state, the pivot pin section 42 corresponds to the sliding section 31. During the rotation of the extended leg assembly 1 towards the retracted state, the pivot pin section 42 can slide relative to the sliding section 31. The leg assembly 1 can drive the pivot pin 4 to switch from the extended slot 31 to the retracted slot 32. That is, at this time, the leg assembly 1 can rotate relative to the exercise bike body and be retracted. It can be understood that by changing the size of the sliding section 31, the rotation angle of the leg assembly 1 from the extended state to the retracted state can be changed, so that the design can be adjusted according to the actual product definition of the extended angle.

[0035] like Figure 5-6As shown, to facilitate user rotation of the pivot pin 4, the pivot pin 4 includes a pivot pin cover 43, which is positioned above the support leg assembly 1, and the limiting sheet metal 3 is positioned below the support leg assembly 1. In this embodiment, the pivot pin cover 43 is provided with locking and unlocking indicators to guide user operation.

[0036] Preferably, to ensure the reliability of the outrigger assembly 1 when locked, the pivot pin 4 is connected to an elastic component. The elastic component provides a force to rotate the pivot pin 4 towards the locked state, so that the outrigger assembly 1 remains locked without external force. In this embodiment, a fixing post 44 is fixedly provided below the pivot pin cover 43, and the elastic component is a torsion spring 45. The torsion spring 45 is sleeved on the pivot pin 4, with one end of the torsion spring 45 abutting against the fixing post 44 and the other end fixed to the outrigger assembly 1. The torsion spring 45 can continuously provide a force to rotate the pivot pin 4 towards the locked state.

[0037] It is worth noting that, such as Figure 12 As shown, when the leg assembly 1 of this embodiment rotates from the retracted state to the unfolded state, the end of the sliding surface 31 near the retracted groove 32 can abut against the pivot pin surface 42 and drive the pivot pin 4 to rotate to the unlocked state. During this process, the torsion spring 45 is compressed, so the torsion spring 45 continuously stores force. Then the pivot pin surface 42 fits against the sliding surface 31 and slides on the sliding surface 31. However, due to the limiting relationship of the sliding surface 31, the pivot pin cover 43 cannot rotate relative to the leg assembly 1. But when the end of the pivot pin 4 reaches the unfolded groove 31, the torsion spring 45 will be released, thereby driving the pivot pin 4 to rotate quickly and lock the leg assembly 1. Thus, when the leg assembly 1 is unfolded, it can be unfolded manually without turning the pivot pin 4. And when the leg assembly 1 is unfolded, the leg assembly 1 can immediately and automatically enter the locking state, which greatly improves the convenience of user operation.

[0038] In this example, four pivots 2 are fixedly connected around the bottom of the exercise bike body. Two pivots 2 are respectively set at the front and rear ends of the exercise bike body. In order to simplify the number of parts and improve assembly efficiency, the limiting sheet metal 3 in this embodiment is connected to two pivots 2 at the same time. The two ends of the limiting sheet metal 3 are symmetrically provided with sliding cut surface 31, storage groove 32 and unfolding groove 31.

[0039] like Figure 6As shown, the outrigger assembly 1 includes a main outrigger beam 11. To ensure the strength of the outrigger assembly 1, the main outrigger beam 11 in this embodiment is made of square steel tubing. A rotating shaft sleeve 12 and a pivot pin sleeve 13 are connected to the end of the main outrigger beam 11. The rotating shaft sleeve 12 is connected to the rotating shaft 2, and the pivot pin 4 is inserted into the pivot pin sleeve 13, with a retaining spring 5 at the lower end. It is worth noting that a limiting groove 14 is provided on the main outrigger beam 11 near the pivot pin sleeve 13. The end of the fixing post 44 below the pivot pin 4 is inserted into the limiting groove 14 to limit the rotation angle of the pivot pin 4, thereby ensuring that the pivot pin 4 can accurately switch between locked and unlocked states. Additionally, as... Figure 7 As shown, in this embodiment, one end of the torsion spring 45 abuts against the fixed post 44, and the other end can also abut against the rotating shaft sleeve 12.

[0040] Preferably, to improve the aesthetics of the outrigger assembly 1, the outrigger assembly 1 in this embodiment further includes an outrigger cover 15, which is fitted onto the outer side of the outrigger main beam 11. Additionally, to prevent the outrigger assembly 1 from directly contacting the ground and scratching the outrigger cover 15, thus affecting its appearance, and also to reduce the noise from friction between the outrigger assembly 1 and the ground, foot pads 6 are provided below the outrigger assembly 1. Preferably, one foot pad 6 is provided at each end of the outrigger assembly 1 to improve its stability.

[0041] This utility model has a simple structure and ingenious design. Through the cooperation of the limiting sheet metal and the pivot pin, the support leg assembly can be rotated within a certain range and limited at a specific angle, so that the support leg assembly can be completely stored under the office exercise bike, greatly reducing the space occupied and facilitating the packaging and transportation of the equipment. Furthermore, the support strength can be ensured when the support leg assembly is unfolded. In addition, by setting the pivot pin cover, it is convenient for users to unlock the support leg assembly, reducing the difficulty of operation and improving the user experience.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
