Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to fitness benches. Background Technology

[0002] Currently, most fitness benches on the market typically include components such as a base, backrest, and seat. Some benches feature a rotatable connection between one end of the backrest and / or seat and the base, allowing users to adjust the tilt angle of the backrest and / or seat relative to the base according to their training needs. This design enables users to maintain the desired tilt angle by changing the contact position between the support components (such as support bars) and the base or backrest / seat, thus allowing for various fitness exercises of different angles and intensities, such as bench presses and sit-ups, improving the functionality and applicability of the fitness bench.

[0003] However, in existing technologies, these types of exercise benches typically lack an effective locking structure between the backrest and / or seat cushion and the base to secure the position of the backrest and / or seat cushion relative to the base during transport or movement. Therefore, during transport, the backrest and / or seat cushion are prone to unexpected rotation due to gravity or external forces, making it difficult to maintain a zero-angle of inclination with the base throughout the process. This could lead to collisions or pinching of the user during transport, posing a potential safety hazard. Furthermore, this unexpected rotation can also make it difficult for the exercise bench to maintain a stable posture during transport, increasing the difficulty of handling. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fitness stool with a self-locking function.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a fitness bench, comprising: Base; A contact pad, one end of which is rotatably connected to the base; The locking mechanism includes a locking pin and a locking seat that cooperate with each other. The locking seat includes a fixed seat, a stop block, and an elastic element. The fixed seat has a receiving opening and a stop portion. Stop blocks are rotatably connected to opposite sides of the receiving opening. The end of the stop block is provided with a guide arc surface for contacting the locking pin to guide the stop block to rotate away from the receiving opening. The elastic element connects the stop block and the fixed seat to drive the stop block to abut against the stop portion. The fixed seat and the two stop blocks together form a receiving cavity that limits the locking pin. One of the locking pin and the locking seat is located on the base, and the other is located on the contact pad.

[0006] Furthermore, the distance between the guide arc surfaces of the two opposing stop portions is less than the diameter of the locking pin.

[0007] Furthermore, the guide arc surface is an arc surface, and the locking pin is cylindrical. When the locking pin is located outside the receiving cavity and tangent to the guide arc surface, the angle between the line connecting the point of tangency between the locking pin and the guide arc surface to the center of the locking pin and the horizontal line passing through the center of the locking pin is α, where α < 45°.

[0008] Furthermore, the stop block has a contact arc surface, which contacts the lock pin when the lock pin is in the receiving cavity.

[0009] Furthermore, the bottom surface of the stop block is provided with a mounting groove, and a rotating shaft is provided in the mounting groove. A portion of the fixed seat extends into the mounting groove and is rotatably connected to the stop block through the rotating shaft.

[0010] Furthermore, the top of the fixing seat is the stop portion, and a portion of the inner top surface of the mounting groove is the contact area that contacts the stop portion.

[0011] Furthermore, the locking mechanism also includes mounting plates, with the mounting plates perpendicularly connected to both ends of the locking pin, and the mounting plates at both ends of the locking pin being arranged opposite to each other.

[0012] Furthermore, it also includes a support member, one end of which is rotatably connected to the contact pad, and the other end of which is provided with a locking post. The base is provided with a plurality of slots that cooperate with the locking post.

[0013] Furthermore, the support member is provided with a handle.

[0014] Furthermore, the contact pad is a seat cushion or a back cushion.

[0015] The beneficial effects of this utility model are as follows: This exercise bench has a locking mechanism. When the contact pad is laid flat, the locking pin and the locking seat cooperate to form a lock, thereby preventing the contact pad from rotating unexpectedly. This facilitates the handling and storage of the exercise bench and improves its safety. The locking mechanism in this exercise bench is easy to operate. During the process of laying the contact pad flat, due to the presence of the guide arc surface, the locking pin can automatically open the stop block and enter the receiving cavity. The elastic element can drive the stop block to return to its original position, thereby closing the opening of the receiving cavity. Only when the force driving the contact pad to rotate exceeds a preset threshold can the locking pin open the stop block again and disengage from the receiving cavity. During the entire operation, the user only needs to rotate the contact pad without any additional operation of the locking mechanism, which greatly facilitates the user's use and enhances the user experience.

[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1 to 5 The exercise bench includes a base 1, a contact pad 2, and a locking mechanism 4. One end of the contact pad 2 is rotatably connected to the base 1. The locking mechanism 4 includes a cooperating locking pin 41 and a locking seat 42. The locking seat 42 includes a fixed seat 421, a stop block 422, and an elastic element 423. The fixed seat 421 has a receiving opening 4211 and a stop portion 4212. The stop blocks 422 are rotatably connected to opposite sides of the receiving opening 4211. The ends of the stop blocks 422 are... A guide arc surface 4221 is provided for contacting the locking pin 41 to guide the stop block 422 to rotate away from the receiving opening 4211. An elastic member 423 connects the stop block 422 and the fixed seat 421 to drive the stop block 422 to abut against the stop part 4212. The fixed seat 421 and the two stop blocks 422 together form a receiving cavity 424 that limits the locking pin 41. One of the locking pin 41 and the locking seat 42 is provided on the base 1, and the other is provided on the contact pad 2.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: This fitness stool has a locking mechanism 4. When the contact pad 2 is laid flat, the locking pin 41 and the locking seat 42 cooperate to form a lock, thereby preventing the contact pad 2 from rotating unexpectedly, facilitating the handling and storage of the fitness stool, and improving the safety of the fitness stool. The locking mechanism 4 in this fitness stool is easy to operate. During the process of laying the contact pad 2 flat, due to the presence of the guide arc surface 4221, the locking pin 41 can automatically open the stop block 422 and enter the receiving cavity 424. The elastic element 423 can drive the stop block 422 to reset, thereby closing the opening of the receiving cavity. Only when the force driving the contact pad 2 to rotate exceeds the preset threshold can the locking pin 41 open the stop block 422 again and disengage from the receiving cavity 424. During the entire operation, the user only needs to rotate the contact pad 2 without any additional operation of the locking mechanism 4, which greatly facilitates the user's use and enhances the user experience.

[0021] Please refer to Figures 3 to 5 Furthermore, the distance between the guide arc surfaces 4221 of the two oppositely arranged stop portions 4212 is less than the diameter of the locking pin 41.

[0022] Please refer to Figure 5 Furthermore, the guide arc surface 4221 is an arc surface, and the locking pin 41 is cylindrical. When the locking pin 41 is located outside the receiving cavity 424 and is tangent to the guide arc surface 4221, the angle between the line connecting the point of tangency between the locking pin 41 and the guide arc surface 4221 to the center of the locking pin 41 and the horizontal line passing through the center of the locking pin 41 is α, where α < 45°.

[0023] As can be seen from the above description, α < 45° can ensure that the locking pin 41 can smoothly open the stop block 422 and enter the receiving cavity 424, thus ensuring the working stability of the locking mechanism 4.

[0024] Please refer to Figure 3 and Figure 4 Furthermore, the stop block 422 has a contact arc surface 4222, which contacts the lock pin 41 when the lock pin 41 is in the receiving cavity 424.

[0025] As can be seen from the above description, the setting of the contact arc surface 4222 allows the stop block 422 to better stop the locking post 41 in the receiving cavity 424, thereby improving the small-angle shaking phenomenon of the contact pad 2 and reducing the noise generated by the exercise bench during transportation.

[0026] Please refer to Figure 3 and Figure 4Furthermore, the bottom surface of the stop block 422 is provided with a mounting groove 4223, and a rotating shaft 425 is provided in the mounting groove 4223. A portion of the fixed seat 421 extends into the mounting groove 4223 and is rotatably connected to the stop block 422 through the rotating shaft 425.

[0027] As can be seen from the above description, the connection between the fixed base 421 and the stop block 422 is simple, reliable, and easy to install.

[0028] Please refer to Figure 3 Furthermore, the top of the fixing seat 421 is the stop part 4212, and a portion of the inner top surface of the mounting groove 4223 is a contact area that contacts the surface of the stop part 4212.

[0029] As can be seen from the above description, using the top of the fixed seat 421 as the stop part 4212 can simplify the structural design of the fixed seat 421. At the same time, the stop part 4212 is in surface contact with the stop block 422, which can improve the damage phenomenon of the stop part 4212 and help extend the service life of the fixed seat 421.

[0030] Please refer to Figure 3 Furthermore, the locking mechanism 4 also includes a mounting plate 411, with the mounting plate 411 vertically connected to both ends of the locking pin 41, and the mounting plates 411 at both ends of the locking pin 41 being arranged opposite to each other.

[0031] As can be seen from the above description, there is a sufficient distance between the locking pin 41 and the contact pad 2 / base 1 on which it is installed to allow the stop block 422 to be avoided.

[0032] Please refer to Figure 1 Furthermore, it also includes a support member 5, one end of which is rotatably connected to the contact pad 2, and the other end of which is provided with a locking post 51. The base 1 is provided with a plurality of locking slots 11 that cooperate with the locking post 51.

[0033] As described above, the tilt angle of the contact pad 2 is adjustable, making it convenient for users to perform a variety of different fitness exercises.

[0034] Please refer to Figure 1 Furthermore, the support member 5 is provided with a handle 52.

[0035] As can be seen from the above description, the presence of handle 52 makes it convenient for users to operate support component 5.

[0036] Furthermore, the contact pad 2 is a seat cushion or a back cushion.

[0037] The first embodiment of this utility model is a fitness bench, which is used to assist users in completing various training movements in a limited space, such as bench press, sit-ups, and bent-over flyes. It is particularly suitable for various scenarios such as home, gym, physical training center, and rehabilitation therapy institution, and can meet the usage requirements of different user groups in strength training, core activation, stretching and relaxation, and functional rehabilitation.

[0038] Please refer to Figure 1 The exercise bench includes a base 1 with a rotatable contact pad 2 on it. One end of the contact pad 2 is rotatably connected to the base 1 via a hinge or shaft 3, allowing the contact pad 2 to rotate relative to the base 1 to accommodate different exercise movements. To prevent the contact pad 2 from rotating unexpectedly relative to the base 1 during transport, the exercise bench also includes a locking mechanism 4, which consists of a locking pin 41 and a locking seat 42. One of the locking pin 41 and the locking seat 42 is located on the base 1, and the other is located on the contact pad 2.

[0039] The contact pad 2 can be a seat cushion, back cushion, headrest, etc.; the elastic element 423 includes, but is not limited to, springs, torsion springs, etc.

[0040] Please refer to Figures 2 to 5 The lock base 42 includes a fixed base 421, a stop block 422, and an elastic element 423. The fixed base 421 has a receiving opening 4211 and a stop portion 4212. The stop blocks 422 are rotatably connected to opposite sides of the receiving opening 4211. The end of the stop block 422 has a guide arc surface 4221 for contacting the lock pin 41 to guide the stop block 422 to rotate away from the receiving opening 4211. The elastic element 423 connects the stop block 422 and the fixed base 421 to drive the stop block 422 to abut against the stop portion 4212. The fixed base 421 and the two stop blocks 422 together form a receiving cavity 424 that limits the locking pin 41.

[0041] The distance between the guide arc surfaces 4221 of the two opposing stop blocks 422 is less than the diameter of the locking pin 41, ensuring that the locking pin 41 must overcome the preload of the elastic element 423 to be squeezed into the receiving cavity 424. In this embodiment, the guide arc surface 4221 is an arc surface, and the locking pin 41 is cylindrical. When the locking pin 41 is located outside the receiving cavity 424 and tangent to the guide arc surface 4221, that is, when the locking pin 41 has not yet opened the stop block 422, the angle between the line connecting the tangent point of the locking pin 41 and the guide arc surface 4221 to the center of the locking pin 41 and the horizontal line passing through the center of the locking pin 41 is α, where α < 45°, thereby ensuring that the locking pin 41 can slide in smoothly and lock automatically. At this time, the angle between the line connecting the center of the guide arc surface 4221 to the center of the locking pin 41 and the horizontal line passing through the center of the locking pin 41 is β, where β < α.

[0042] Please refer to Figure 3 and Figure 4 The stop block 422 also has a contact arc surface 4222. When the locking pin 41 is in the receiving cavity 424, the contact arc surface 4222 contacts the locking pin 41 to form a stable clamp and prevent shaking.

[0043] In one or more embodiments, the bottom surface of the stop block 422 is provided with a mounting groove 4223, and a rotating shaft 425 is provided in the mounting groove 4223. A portion of the fixed seat 421 extends into the mounting groove 4223 and is rotatably connected to the stop block 422 through the rotating shaft 425. In this embodiment, the top end of the fixed seat 421 is a stop portion 4212, and a portion of the inner top surface of the mounting groove 4223 is a contact area that contacts the surface of the stop portion 4212. When the stop block 422 returns to its original position under the action of the elastic member 423, the contact area contacts the surface of the stop portion 4212, thereby achieving rigid limiting.

[0044] Optionally, the locking mechanism 4 also includes mounting plates 411, with mounting plates 411 vertically connected to both ends of the locking pin 41. The two mounting plates 411 are arranged opposite to each other. In some embodiments, the mounting plates 411 are fastened to the frame of the contact pad 2 by bolts, so that the locking pin 41 is suspended and kept horizontal.

[0045] Please refer to Figure 1 The exercise bench also includes a support member 5, one end of which is rotatably connected to the contact pad 2, and the other end has a locking post 51. The base 1 has multiple slots 11 that mate with the locking posts 51. By inserting the locking posts 51 into different slots 11, the tilt angle of the contact pad 2 can be adjusted and fixed. Preferably, the support member 5 has a handle 52, which makes it easy for users to lift the support member 5 to adjust the angle or fold it for storage.

[0046] Please refer to Figures 1 to 5 When moving the exercise bench, first fold the contact pad 2 downwards. The locking pin 41 automatically pushes open the stop block 422 along the guide arc surface 4221 and enters the receiving cavity 424. After the elastic element 423 returns to its original position, the stop block 422 clamps the locking pin 41, and the contact pad 2 and the base 1 are locked together to prevent unexpected rotation. When it needs to be unfolded for use, simply lift the contact pad 2 upwards. The locking pin 41 pushes against the guide arc surface 4221 in the opposite direction, the stop block 422 opens again, the locking pin 41 smoothly disengages, and the lock is automatically released. Then, the support element 5 can be used to select the desired angle and lock it in place to enter the training state.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
