[0002] The bench press is a common piece of fitness equipment, mainly consisting of a bench press plate, a rack and a safety frame, and is used to exercise the upper body muscles.

[0003] In the prior art, bench presses are typically flat, covered with a soft material to enhance comfort. However, because the human body is not completely symmetrical, flat bench presses are unable to adapt to or correct body asymmetries when performed on them. This asymmetry can lead to uneven distribution of upper body muscle strength during bench press training, which can cause one side of the body to become more developed than the other over time, leading to upper body muscle imbalance. Furthermore, this uneven strength can cause muscles, joints, or ligaments on one side to bear greater stress than those on the other, increasing the risk of injury.

[0004] Therefore, the existing technology has defects and deficiencies and needs further improvement and development. Utility Model Content

[0039] Please refer to Figures 1 to 2In a first embodiment of the present application, a bench press 10 is provided. The bench press 10 includes a headrest section 11, a hip support section 12, a backrest section 13, and a bench body 14. The headrest section 11 is disposed at one end of the bench body 14 to provide comfortable head support and reduce neck pressure during training. The headrest section 11 is disposed at the end of the bench body 14 facing away from the headrest section 11 and is used to support the user's hips, increase stability, and reduce pressure on the lower back. The backrest section 13 is disposed between the headrest section 11 and the hip support section 12 and is the main support area during bench press training. The backrest section 13 is provided with a balancing portion 131 and a lifting mechanism 132. The lifting mechanism 132 is connected to the balancing portion 131 and is located below the balancing portion 131. Specifically, the balancing portion 131 is located above the backrest section 13, directly contacting the user's shoulder blades and ribs between the spine. The balancing part 131 is an adjustable structure that can be adjusted according to the user's body shape and strength distribution to adapt to the width of the user's shoulders and strength output. The lifting mechanism 132 is located below the balancing part 131 and is driven mechanically or electrically, allowing the balancing part 131 to be adjusted in height according to the asymmetric strength distribution of the user when performing the bench press. The control of the lifting mechanism 132 can be manual or automatic. If it is automatic, it can sense the user's strength output through a sensor and automatically adjust it. The bench press board 10 uses the lifting mechanism 132 to adjust and compensate for the asymmetry of the spinal joint muscles of the body, helping the user to achieve a uniform distribution of muscle strength during training, thereby reducing the risk of muscle imbalance. Long-term use can promote the balanced development of muscles on both sides of the body, prevent potential injuries caused by improper posture, and reduce unnecessary pressure on joints and ligaments. Not only does it improve the comfort and efficiency of use, but it also increases the safety and effectiveness of training.

[0040] Specifically, in order to better illustrate the function of the bench press plate 10 of the present application, it is taken as an example that when the right balance block rises, the user's center of gravity shifts to the left to balance the user's body asymmetry.

[0041] When you shift your center of gravity to the left with a counterweight during exercise, more weight is carried on your left leg. This increases intra-abdominal pressure on the left side because your core muscles (including your abdominal muscles) need to work harder to maintain stability and balance. Because of the increased intra-abdominal pressure, the diaphragm on the left side doesn't need to descend as much to facilitate deep breathing. Because the support of intra-abdominal pressure reduces the need for the diaphragm to descend, this helps maintain a more stable breathing pattern.

[0042] Because the diaphragm doesn't sink as much, the left ribs are more free to evert (expand outward). This eversion helps expand the rib cage, allowing the left lung to expand more fully during breathing. The expansion of the left rib cage affects the right rib cage through a cascade of muscular and skeletal effects. As the left rib cage expands, intrapleural pressure (the pressure around the lungs) and intra-abdominal pressure on the right side decrease as the entire rib cage adjusts to the changes on the left side.

[0043] Due to the reduction in right-sided intrapleural and intra-abdominal pressure, the right diaphragm can descend more freely, facilitating deeper inhalations from the right side. This adjustment improves overall respiratory efficiency. With this dynamic adjustment of the left and right rib cages, the rotation and mobility of the entire rib cage improve. This not only impacts breathing but also upper body flexibility and range of motion.

[0044] Scapular mobility depends on the stability and freedom of the ribcage. Improving the rib cage directly increases freedom of movement in the shoulder area, enabling more efficient movement of the scapula and supporting arm and upper body movements. The body's spiral chain is a functional connection of muscles, bones, and joints that works together during rotation and lateral bending. Improving the ribcage and scapula described above allows the spiral chain to function more effectively, enhancing overall coordination and power output.

[0045] It can be seen that after the user's body asymmetry is balanced by the balance block, the structure and function of the entire body are optimized during training, thereby improving various problems caused by asymmetry and enhancing the overall exercise efficiency and health status.

[0046] Please refer to Figure 3 In some specific embodiments, the backrest section 13 is further provided with a longitudinal beam 133, which is arranged along the longitudinal axis of the bench press body 14. Specifically, the longitudinal beam 133 is arranged inside the backrest section 13 along the longitudinal axis of the bench press body 14. The longitudinal beam 133 is located along the longitudinal axis of the bench press body 14 and runs through the center of the backrest section 13, providing structural support and stability. The provision of the longitudinal beam 133 enhances the load-bearing capacity of the backrest section 13, ensuring that the backrest section 13 remains stable and resists deformation during heavy weight training. There are multiple balancing sections 131, each of which is arranged on either side of the longitudinal beam 133. Specifically, multiple balancing sections 131 are arranged on both sides of the longitudinal beam 133. These balancing sections 131 are arranged on both sides of the longitudinal beam 133 and can be independently adjusted to accommodate different user's body structures and power output. Each balancing part 131 can be independently raised or lowered, and can be automatically or manually controlled by the lifting mechanism 132 to accurately adjust to achieve optimal power balance and body symmetry.

[0047] In some specific embodiments, the backrest section 13 is provided with a plurality of balancing grooves 134, which are used to accommodate and guide the movement of the balancing portion 131. Each of the balancing grooves 134 is connected to the longitudinal beam 133. Each balancing groove 134 has a specific depth and width, tightly integrated with the structure of the longitudinal beam 133, ensuring the stability of the overall structure and smooth adjustment of the balancing portion 131. The balancing portions 131 are arranged in a one-to-one correspondence within the balancing grooves 134. Each balancing portion 131 can move up and down within its corresponding balancing groove 134, precisely controlled by the lifting mechanism 132. This one-to-one correspondence allows each balancing portion 131 to be independently adjusted to best suit the user's body shape and strength distribution.

[0048] In some specific embodiments, the balancing part 131 can be raised and lowered on both sides independently, or on both sides simultaneously, thereby allowing each balancing part 131 to be adjusted independently to maximize adaptation to the user's body shape and strength distribution, further improving the practicality and safety of the bench press 10.

[0049] Please refer to Figures 3 and 4 By setting the balancing part 131 in the balancing groove 134, not only can the position and movement of the balancing part 131 be better fixed and guided, but the overall stability and durability of the bench press plate 10 can also be enhanced through the structure of the balancing groove 134. The provision of the balancing groove 134 allows the balancing part 131 to adjust its position more accurately, providing more refined adaptability to the user's body shape and training needs. Through precise adjustment of the balancing part 131, it is possible to more effectively help the user correct the imbalance of force output, promote balanced muscle development, and reduce the risk of injury during training. At the same time, the combination of the balancing groove 134 and the balancing part 131 also makes adjustment more convenient and quick, thereby improving the efficiency of training.

[0050] Please refer to Figures 3 and 4 In some specific embodiments, there are two balancing parts 131, and the two balancing parts 131 are both arranged along the width direction of the bench press body 14, and the two balancing parts 131 are respectively arranged on both sides of the width direction of the bench press body 14. Specifically, the two balancing parts 131 are both arranged along the width direction of the bench press body 14. Each balancing part 131 is located on both sides of the width direction of the bench press body 14, that is, one balancing part 131 is located on the left and the other balancing part 131 is located on the right. By arranging a balancing part 131 on both sides in the width direction, the body asymmetry of the user when performing the bench press can be more effectively adjusted. This symmetrical arrangement helps to balance the power output of the left and right muscle groups, thereby improving the balance and effect of the training.

[0051] The presence of a balancing portion 131 on each side of the width allows the bench press 10 to better adapt to users of varying body shapes and strengths. For users with significant left-right strength imbalances or larger users, more personalized support and adjustments can be provided, helping them to more effectively perform strength balance training.

[0052] In some embodiments, a neck support section 16 is provided between the headrest section and the backrest section. The neck support section 16 is used to increase the user's cervical curvature. The height of the neck support section 16 can be adjusted up and down, and can also be swung left and right, thereby protecting users of different body shapes from adjusting the cervical curvature during bench press, avoiding injuries to users during bench press training, and further increasing the practicality and convenience of the bench press board 10.

[0053] In some embodiments, the transverse cross-section of the neck support section 16 is semicircular, and the cross-sectional radius is 7 cm to 10 cm, thereby increasing the user's cervical curvature according to user needs, further increasing the practicality and convenience of the bench press 10.

[0054] In some embodiments, the headrest section 11 is provided with a lifting knob, and the user can adjust the height of the headrest section as needed, and can also synchronously drive the neck support section 16 to rise and fall. During use, the headrest section 11 can swing left and right with the user's head, thereby enhancing the protection of the user's head and cervical spine, and further increasing the practicality and safety of the bench press 10.

[0055] In some specific embodiments, the balancing parts 131 are hinged to the longitudinal beam 133. Specifically, the hinge allows each balancing part 131 to rotate relative to the longitudinal beam 133 at the connection point, so that each balancing part 131 can adapt to different angle requirements. By hinged connection, the balancing part 131 can adjust the angle according to the user's body shape and specific posture requirements during bench press, so as to better match the shape of the user's shoulders and back, and provide the user with support that is more in line with personal characteristics. The hinged connection not only makes the adjustment process more convenient and quick, but also can make real-time adjustments according to the dynamic changes of the user during training. It is conducive to maintaining the correct posture during long-term or high-intensity training, and reducing stress and potential injuries caused by improper posture.

[0056] Please refer to Figures 3 and 4In some specific embodiments, a limiting step 1341 is provided in the balancing groove 134, and the limiting step 1341 is located below the balancing part 131. Specifically, a limiting step 1341 is provided in each balancing groove 134, and these limiting steps 1341 are located below the balancing part 131. The main function of the limiting step 1341 is to provide a physical stopping point or limiting point for the balancing part 131 to prevent the balancing part 131 from excessively falling, thereby ensuring the safety of use and the stability of the equipment. The provision of the limiting step 1341 ensures that the balancing part 131 does not exceed the range of motion when being adjusted and not in use, prevents the balancing part 131 from deviating from the predetermined track or position, thereby avoiding potential damage to the equipment or injury to the user, and also helps to maintain the long-term stability and durability of the equipment.

[0057] Please refer to Figures 4 and 5 In some specific embodiments, the lifting mechanism 132 includes a power assembly 1321 and a lifting assembly 1322. The lifting assembly 1322 includes a screw rod 1323 and a nut 1324. A lifting hole 1311 is provided on the side of the balancing portion 131 facing the balancing portion 131. The nut 1324 is fixedly mounted in the fixing hole. The screw rod 1323 extends into the lifting hole 1311. The power assembly 1321 is connected to the screw rod 1323. Specifically, the rotation of the screw rod 1323 is driven by the power assembly 1321. The nut 1324 is fixed to the balancing portion 131, and moves with the rotation of the screw rod 1323 to achieve the lifting function. The installation of the lifting mechanism 132 not only improves the technical performance of the bench press 10, making the equipment more precise and convenient to adjust, but also increases safety and comfort during use. Users can easily adjust the height of the balancing portion 131 according to their personal physical condition and training needs, ensuring correct posture and force distribution during training.

[0058] In some specific embodiments, the rotation of the spiral rod 1323 is driven by the user shaking the lifting handle, and the upper wall and side wall of the lifting handle are provided with scale lines, so that the user can accurately adjust the height of the balance part 131 according to personal physical conditions and training needs to ensure that the correct posture and force distribution are maintained during training.

[0059] Please refer to Figure 6In some specific embodiments, the lifting mechanism 132 includes a hydraulic cylinder 1325 and a connecting rod 1326, one end of the connecting rod 1326 is connected to the hydraulic cylinder 1325, and the other end of the connecting rod 1326 is connected to the balancing part 131. Specifically, the lifting mechanism 132 is composed of a hydraulic cylinder 1325 and a connecting rod 1326, wherein the hydraulic cylinder 1325 is used to generate a driving force, and the connecting rod 1326 is used to transmit the power to the balancing part 131. The hydraulic cylinder 1325 serves as the main power source of the lifting mechanism 132. The hydraulic cylinder 1325 pushes or pulls the connecting rod 1326 through changes in liquid pressure to achieve precise power output. One end of the connecting rod 1326 is connected to the hydraulic cylinder 1325, and the other end is connected to the balancing part 131. The connecting rod 1326 ensures the efficiency of force transmission and the precise adjustment of the balancing part 131, allowing the balancing part 131 to move vertically according to training needs.

[0060] Please refer to Figures 4 to 6 The second embodiment of the present application provides a bench press 20, which includes the bench press plate 10 as described above. It can be seen that the bench press 20 provided in this embodiment has the advantage of using the lifting mechanism 132 to adjust and compensate for the asymmetry of the spinal joint muscles of the body.

[0061] Please refer to Figures 4 to 6 In some specific embodiments, the bench press 10 further includes a support frame 21, with the bench press 10 disposed on the upper end of the support frame 21; specifically, the bench press 10 is disposed on the upper end of the support frame 21. The design of the support frame 21 not only provides the necessary structural support, but also ensures the stability and safety of the bench press 10 during use. The hydraulic cylinder 1325 is disposed on the support frame 21. The support frame 21 not only enhances the overall structural stability of the bench press 10, but also enables the hydraulic cylinder 1325 and other mechanical components to operate in a more rational and safe environment. The hydraulic cylinder 1325 is disposed on the support frame 21. This arrangement facilitates the stable fixation and protection of the hydraulic cylinder 1325, while also making the connection between the hydraulic cylinder 1325 and the connecting rod 1326 more convenient and effective. By mounting the hydraulic cylinder 1325 on the support frame 21, the mechanical strength and operational response speed of the entire lifting mechanism 132 are improved, while also facilitating maintenance and repair. The design of the support frame 21 ensures the stability of the bench press 10 when bearing heavy loads, reduces shaking or tilting during movement of the equipment, and provides a safer and more reliable training environment.

[0062] In summary, the present application provides a bench press and a bench press machine. A bench press comprises: a bench body; a headrest section disposed at one end of the bench body; a hip support section disposed at the end of the bench body facing away from the headrest section; and a backrest section disposed between the headrest and hip support sections. The backrest section is provided with a balancing portion and a lifting mechanism, the lifting mechanism being connected to the balancing portion and located below the balancing portion. The bench press comprises a headrest section, a hip support section, a backrest section, and a bench body. By providing the balancing portion and the lifting mechanism on the backrest section, the balancing portion abuts against the ribs between the shoulder blades and the spine, and the lifting mechanism is used to adjust and compensate for asymmetry in the spinal joint muscles. This helps to evenly develop muscles on both sides of the body, reducing muscle imbalance caused by unilateral weight gain, thereby promoting overall harmonious development of the body during long-term training. It can prevent potential injuries caused by improper posture and reduce unnecessary stress on joints and ligaments during training.
