[0020] like Figure 1 As shown in Figure 6, according to an embodiment of this application, a dumbbell bench is provided, which includes a first base 1, a second base 2, and a main frame 3. The first base 1 is fixedly connected to the main frame 3 via a first connecting piece 11 and a fixing bolt 12. The second base 2 is fixedly connected to the main frame 3 via a second connecting piece 21 and a fixing bolt 22. By adding the first connecting piece 11 and the second connecting piece 21, the overall stability and safety of the device are improved, ensuring that the main frame 3 will not slide or tilt between the first base 1 and the second base 2 during high-intensity training. A seat cushion 4 and a back cushion 5 are connected above the main frame 3 to provide a comfortable training platform suitable for various training postures. A right elbow pad assembly 8 for assisting dumbbell training is connected to the left side of the back cushion 5; a left elbow pad assembly 9 for assisting dumbbell training is connected to the right side of the back cushion 5. The design of the right elbow pad assembly 8 and the left elbow pad assembly 9 takes into account the user's need to adjust the hand position during dumbbell training, providing a more flexible and diverse training method. The front end of the first base 1 is also provided with a handle 10 for users to hold when moving the dumbbell rack, so as to improve the convenience of movement.
[0021] The right elbow pad assembly 8 includes a right elbow pad 81 and a right elbow pad bracket 82 fixedly connected to the bottom of the right elbow pad 81, wherein the right elbow pad bracket 82 is fixedly connected to the main frame 3. The left elbow pad assembly 9 includes a left elbow pad 91 and a left elbow pad bracket 92 fixedly connected to the bottom of the left elbow pad 91, wherein the left elbow pad bracket 92 is fixedly connected to the main frame 3. This structure not only increases the overall structural rigidity but also allows users to obtain additional hand or forearm support when performing supine, sit-up, or dumbbell exercises, thereby improving training efficiency and comfort. The right elbow pad 81 and left elbow pad 91 are symmetrically arranged on the left and right sides of the pad body to provide hand or forearm support when the user performs supine, sit-up, or dumbbell exercises. This layout ensures balanced force on both sides, helps maintain body balance, and provides even support during training, enhancing training effects.
[0022] In some embodiments, such as Figure 1 ~ Figure 4As shown, the main body of the right elbow pad 81 and the left elbow pad 91 is semi-cylindrical, with its arc-shaped outer surface facing outwards to improve comfort and anti-slip performance when the forearm contacts the body. The semi-cylindrical structure can better conform to the natural curvature of the human forearm, increase the contact area, and reduce local pressure, thereby effectively improving the comfort when supporting the body. At the same time, the arc-shaped surface helps guide the forearm to fit stably, preventing the hand from slipping during training, which could lead to deformation of the movement or accidental slippage, significantly improving the safety and stability of training.
[0023] In some embodiments, such as Figure 1 , Figure 5 As shown in Figure 6, the seat cushion 4 and back cushion 5 are each equipped with a reinforced structure. Specifically, the bottom of the seat cushion 4 is connected to a seat frame 41, while the bottom of the back cushion 5 is connected to a back cushion frame 51. These two metal reinforcing plates not only constitute the load-bearing skeleton of the seat cushion 4 and back cushion 5 respectively, but also significantly enhance the overall structural strength of the seat cushion 4 and back cushion 5, and effectively transfer the load to the main frame 3, ensuring the stability and durability of the entire dumbbell bench during use.
[0024] Furthermore, the seat frame 41 and backrest frame 51 are rotatably connected via a pivot 7, allowing the seat 4 and backrest 5 to rotate relative to each other around the pivot 7. This construction enhances the user's relative flexibility in adjusting the angle of the seat 4 and backrest 5, enabling them to adjust to the most suitable training position according to their individual needs, whether performing sit-ups or dumbbell exercises. This design greatly enhances the functionality and adaptability of the dumbbell bench, allowing users of different body types and training goals to obtain the best training experience. At the same time, this also increases the versatility of the equipment, extending its functionality beyond a single training method to support a variety of different exercise modes.
[0025] In some embodiments, such as Figure 2 and Figure 5As shown, the outer side plates on both sides of the back pad frame 51 are provided with multiple pairs of first fixing holes 511 spaced apart along their length. This design allows the right elbow pad frame 82 and the left elbow pad frame 92 to be selectively connected to a pair of first fixing holes 511 at corresponding positions on the left and right sides via fixing bolts. In this way, users can flexibly adjust the lateral mounting positions of the right elbow pad assembly 8 and the left elbow pad assembly 9 according to their individual needs or training type, thereby changing their horizontal positions relative to the back pad 5. This structure not only increases the flexibility and adaptability of the equipment, allowing users of different body types or with different training needs to find the most suitable dumbbell assist device position, but also improves training effectiveness and comfort to a certain extent. For example, when performing specific arm or chest muscle exercises, appropriately adjusting the positions of the corresponding right elbow pad assembly 8 and left elbow pad assembly 9 can help users better target the muscle groups while reducing discomfort or potential risks during exercise. In addition, this adjustable design also extends the service life of the equipment because it can adapt to more diverse usage scenarios and needs, meeting the long-term usage requirements of a wider range of users.
[0026] In some embodiments, such as Figures 1-2 , Figure 5 As shown, a first angle locking structure 42 is installed below the seat cushion frame 41. The first angle locking structure 42 includes an arc-shaped adjustment ruler 421, one end of which is fixedly connected to the seat cushion frame 41. Eight adjustment holes 4211 are distributed along the arc of the arc-shaped adjustment ruler, corresponding to angles of 30°, 20°, 10°, 0°, -10°, -20°, -30°, and -37.5° respectively. These eight adjustment holes 4211 at different angles allow the user to select different angles for locking as needed. A first spring pin 422 is provided on the main frame 3. When the seat cushion frame 41 rotates around the pivot 7 to a preset angle, such as 0°, locking can be achieved by passing the first spring pin 422 through the adjustment hole 4211 corresponding to the 0° position on the main frame 3, thereby securely holding the seat cushion frame 41 at the 0° angle position. This design offers users great flexibility, allowing them to adjust the mat's angle according to personal preferences or specific training needs. Whether performing sit-ups or other types of training, users can find the most suitable position. Furthermore, locking the angle in this way ensures the stability and safety of the entire structure during use, preventing accidents caused by angle changes and providing users with a safe and comfortable training environment.
[0027] In some embodiments, such as Figure 1 , Figure 2 , Figure 5As shown, a second angle locking mechanism 52 is installed below the backrest frame 51. The second angle locking mechanism 52 includes an arc-shaped adjustment ruler 521, one end of which is fixedly connected to the backrest frame 51. On the surface of the arc-shaped adjustment ruler 521, multiple adjustment holes 5211 are distributed along its arc. These adjustment holes 5211 correspond to different preset angle values, specifically 0°, 10°, 20°, 30°, -10°, -37.5°, 45°, 52.5°, 60°, 67.5°, 75°, and 85°. This design allows users to precisely adjust the angle of the backrest 5 according to their personal needs. A second spring pin 522 is provided on the main frame 3. When the backrest frame 51 rotates around the pivot 7 to a preset angle (e.g., 30°), the second spring pin 522 on the main frame 3 can pass through the main frame 3 and the adjustment hole 5211 corresponding to the 30° position, thereby firmly locking the backrest frame 51 at the 30° position. In this way, users can flexibly adjust and lock the angle of the back pad 5 according to their training requirements or comfort preferences to achieve the best user experience and training effect. This design not only enhances the functionality and adaptability of the equipment, but also ensures the safety and stability of use, allowing users with different needs to obtain a satisfactory training experience.
[0028] In some embodiments, such as Figure 1 , Figures 5-7 As shown, the dumbbell bench also includes a foot hook 6, which is located at one end of the backrest 5. The foot hook 6 is connected to the support frame 31 via a length-adjustable first length locking structure 61, thereby facilitating the adjustment of the extension length of the foot hook 6 in the front-back direction. Specifically, the first length locking structure 61 includes a first outer tube 611, the outer wall of which is connected to the support frame 31; a second fixing hole 6110 is provided on the tube wall of the first outer tube 611. A first inner tube 612 is slidably inserted inside the first outer tube 611, and has multiple spaced adjustment holes 6120 along its length. The outer end of the first inner tube 612 is fixedly connected to the foot hook 6. This design allows the first inner tube 612 to extend and retract relative to the first outer tube 611 to adjust the front-back extension length of the foot hook 6. When the user selects the target extension length, the first spring knob 613 can be passed through the second fixing hole 6110 of the first outer tube 611 and aligned with the corresponding adjustment hole on the first inner tube 612 to lock the relative positions of the two. This design allows the hook stand 6 to be precisely adjusted according to the user's individual needs or training objectives, enhancing the flexibility and adaptability of the equipment. Furthermore, this first length adjustment structure 61 not only facilitates personalized settings based on the user's body size or training preferences but also ensures safety and stability, providing a comfortable and efficient training environment.
[0029] In one embodiment, such as Figure 4 , Figure 6B As shown, the hook bracket 6 includes a hook rod 6a and a knee bend support rod 6b. The hook rod 6a and the knee bend support rod 6b are connected by a connecting rod 6c, one end of which has a fixing hole. The hook rod 6a is connected to the knee bend support rod 6b through a third angle locking structure 64 to adjust and lock the rotation angle of the hook rod 6a relative to the knee bend support rod 6b. The third angle locking structure 64 includes an arc adjustment plate 601 and a fixing bolt. The arc adjustment plate 601 is fixedly connected to the knee bend support rod 6b. The arc adjustment plate 601 is rotatably mounted on the hook rod 6a. The surface of the arc adjustment plate 601 has multiple spaced adjustment holes 602 along its preset arc angle direction. When the hook rod 6a rotates to the target angle, the fixing bolt 603 passes through the fixing hole on the connecting rod 6c and engages with the corresponding adjustment hole 602 on the arc adjustment plate 601 to lock the hook rod 6a at the corresponding angle position. The outer wall surface of the curvature adjustment plate 601 is also connected to a carrying tube 20, which makes it easy to hold and apply force when moving the dumbbell bench.
[0030] The foot hook rod 6a is connected to the knee bend support rod 6b via a third angle locking structure 64, enabling adjustable rotation angle adjustment and position locking of the foot hook rod 6a relative to the knee bend support rod 6b. Specifically, the third angle locking structure 64 includes an arc adjustment plate 601 and a fixing bolt 603. The arc adjustment plate 601 is fixedly connected to the knee bend support rod 6b and rotatably mounted on the foot hook rod 6a, allowing it to adjust the angle of the knee bend support rod 6b relative to the foot hook rod 6a. The arc adjustment plate 601 has multiple spaced adjustment holes 602 along its preset rotation angle direction. These adjustment holes are arranged according to the required arc angle, corresponding to different tilt angle positions. When the user rotates the foot hook bar 6a to the target angle according to their leg length, training posture, or comfort needs, the fixing bolt 603 passes through the fixing hole on the connecting rod 6c and engages with the corresponding adjustment hole 602 on the arc adjustment plate 601 to lock it in place, thereby fixing the relative angle between the foot hook bar 6a and the knee bend support bar 6b. This structure enables multi-angle adaptation of the footrest area, meeting the personalized needs of users of different heights or training habits for foot support angles, and improving the fit and stability during exercise.
[0031] In some embodiments, the second length locking structure 62 is directly or indirectly connected to the support frame 31. In one embodiment, such as Figure 4 As shown in Figure 6, the hook tripod 6 is fixedly connected to the first inner sleeve 612 of the first length locking structure 61 via an adjustable second length locking structure 62. The second length locking structure 62 is used to adjust the extension length of the hook tripod 6 in the vertical direction. This design allows users to adjust the height of the hook tripod 6 according to their individual height or training needs, thereby obtaining the best user experience.
[0032] Specifically, the second length locking structure 62 includes a second outer sleeve 621 and a second inner sleeve 622. The outer wall of the second outer sleeve 621 is connected to the first inner sleeve 612 of the first length locking structure 61. A fixing hole is provided on the wall of the second outer sleeve 621. The second inner sleeve 622 is slidably inserted inside the second outer sleeve 621 and has multiple spaced first adjustment holes 6221 along its length. The outer end of the second inner sleeve 622 is fixedly connected to the hook bracket 6. This design allows the second inner sleeve 622 to extend and retract relative to the second outer sleeve 621 to adjust the vertical extension length of the hook bracket 6. After the user selects the target extension length, the second spring knob 623 can be passed through the fixing hole of the second outer sleeve 621 and aligned with the corresponding first adjustment hole 6221 on the second inner sleeve 622 before locking, thus fixing their relative positions. This mechanism not only provides the user with flexibility in height adjustment but also ensures the stability and safety of the hook bracket 6 during use. In this way, users can easily adjust the height of the device according to their needs, finding the most suitable position for themselves whether doing sit-ups or other forms of exercise, and enjoying a more comfortable and efficient fitness experience. In some embodiments, the second length locking structure 62 also includes a crossbar, which is directly connected to the support frame 31.
[0033] In one embodiment, such as Figures 2-6B As shown, the hook bracket 6 includes a hook rod 6a and a knee bend support rod 6b. The hook rod 6a and the knee bend support rod 6b are connected by a third length locking structure 63 so as to adjust the relative distance between the hook rod 6a and the knee bend support rod 6b to meet the needs of different users.
[0034] Specifically, the third length locking structure 63 includes a connecting rod 6c, which comprises a third outer sleeve 631 and a third inner sleeve 632. The outer wall of the third outer sleeve 631 is fixedly connected to the foot hook rod 6a. A fixing hole is provided on the wall of the third outer sleeve 631. The third inner sleeve 632 is slidably inserted inside the third outer sleeve 631 and has multiple spaced second adjustment holes 6321 along its length. The outer end of the third inner sleeve 632 is fixedly connected to the knee bend support rod 6b. This design allows the third inner sleeve 632 to extend or retract relative to the third outer sleeve 631 to adjust the distance between the two sets of foot pedals. After the user selects the target distance, the third spring knob 633 can be passed through the fixing hole of the third outer sleeve 631 and aligned with the corresponding second adjustment hole 6321 on the third inner sleeve 632 to lock the relative positions of the two pedals. This design not only provides high flexibility and personalized settings, allowing users of different body sizes to find the most suitable foot position, but also ensures stability and safety during use. In this way, users can easily adjust the distance of the foot pedals according to their body size or training needs, so as to get the best support and comfort whether doing sit-ups or other forms of exercise, thereby improving the overall training effect.
[0035] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: First, the dumbbell bench involved in this application integrates a seat cushion 4, a back cushion 5, a right elbow pad assembly 8, a left elbow pad assembly 9, and a foot hook 6, making the dumbbell bench not only suitable for regular supine and sit-up training, but also effectively assisting in various dumbbell training, with multiple functions to meet the diverse fitness needs of users.
[0036] Secondly, this application connects the first base 1 and the second base 2 to the main frame 3 via the first connecting piece 11, the second connecting piece 21 and the fixing bolts 12 and 22 respectively, and sets the seat frame 41 and the back frame 51 at the bottom of the seat cushion 4 and the back cushion 5 respectively as load-bearing skeletons, which significantly enhances the strength and stability of the overall structure, effectively prevents sliding, tilting or deformation during training, and ensures the safety of the user.
[0037] Third, the hook stand 6 of this application, through the first length locking structure 61 and the second length locking structure 62, achieves adjustable position in the front-back direction and the up-down direction, which can adapt to the usage needs of users with different heights and body types, and improve the comfort and effectiveness of training.
