[0043] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0044] As shown in the attached Figure 1 to the attached Figure 6 As shown, the embodiment of the present utility model provides a multifunctional abdominal exercise board, which includes a bottom plate, a sliding device 50 and push-up handles 20. During training, the bottom plate 10 is placed on a plane and serves as the load-bearing structure of the entire trainer. Both the sliding device 50 and the push-up handles 20 are detachably connected to the bottom plate 10, enabling the trainer to not only perform extended abdominal exercises but also push-up exercises.

[0045] The bottom plate 10 of this embodiment has a straight plate structure, with a larger contact area with the plane, more stable placement, and improved stability and safety for the trainer during exercise. On both sides of the upper surface of the bottom plate 10 in the width direction, a set of tracks 18 are respectively provided. The tracks 18 extend along the length direction of the bottom plate 10 and are parallel to each other. The sliding device 50 is movably connected to the bottom plate 10 and can slide along the tracks 18. The sliding device 50 is mainly used for the trainer to perform extended abdominal exercises.

[0046] As shown in the attached Figure 1 and the attached Figure 5As shown in the figure, on the bottom plate 10, each group of tracks 18 includes a sliding track 181 and two rolling tracks 182. The sliding track 181 is located between the two rolling tracks 182. Correspondingly, the sliding device 50 includes a sliding member 51 and a rolling member 52 at the bottom. The sliding member 51 cooperates with the sliding track 181 for sliding. The sliding track 181 is a structure that penetrates up and down. The sliding member 51 passes through the sliding track 181 and is provided with a limiting block at the bottom, which cooperates with and is clamped to the bottom of the sliding track 181 to prevent the sliding device 50 from detaching from the sliding track 181. The rolling member 52 can be one of a roller, a bearing, or a ball, and rolls in cooperation with the rolling track 182.

[0047] In this embodiment, since the tracks 18 provided on the bottom plate 10 will reduce the structural strength of the bottom plate 10, when the trainer applies force to the bottom plate 10 and the sliding device 50 thereon, the corresponding positions of the tracks 18 are prone to deformation and the force application effect is not good. Therefore, as shown in the appendix Figure 2 As shown in the figure, a number of reinforcing ribs 118 at the bottom of the bottom plate 10 of this embodiment correspond to the two rolling tracks 182. That is, on the first bottom plate 11 and the second bottom plate 12, a number of reinforcing ribs 118 are provided below the two rolling tracks 182 on each side, and the bottom surface of the reinforcing ribs 118 is flush with the bottom surface of the bottom plate 10. Thus, the force of the trainer can be transmitted to the plane through the reinforcing ribs 118 to provide a supporting force for the sliding device 50 during sliding and prevent the bottom plate 10 and the tracks 18 from deforming and affecting the sliding effect.

[0048] As shown in the appendix Figure 1 As shown in the figure, a number of handle fixing holes 13 are provided on the bottom plate 10. The handle fixing holes 13 are located between the two groups of tracks 18, and the push-up handle 20 is detachably connected to the handle fixing holes 13. As shown in the appendix Figure 7 As shown in the figure, when push-up training is required, the trainer can rotate the appropriate handle fixing holes 13 by himself and insert the push-up handle 20 into the handle fixing holes 13 to fix the push-up handle 20 on the bottom plate 10.

[0049] In order to reduce the storage volume of the trainer, the bottom plate 10 of this embodiment is a foldable structure. Specifically, the bottom plate has a folding line 16 that divides the bottom plate 10 into a first bottom plate 11 and a second bottom plate 12. The first bottom plate 11 and the second bottom plate 12 can be folded relative to the folding line 16, and after folding, the bottoms of the first bottom plate 11 and the second bottom plate 12 are attached, making the volume of the folded bottom plate 10 smaller.

[0050] As shown in the appendix Figure 2As shown, the first bottom plate 11 and the second bottom plate 12 are connected by a rotating connecting member 30. Specifically, connecting portions 111 are provided at opposite ends of the first bottom plate 11 and the second bottom plate 12. The connecting portion 111 includes two spaced positioning plates 112, a positioning groove 113 located on the positioning plate 112, and a receiving groove 114 between the two positioning plates 112. Four connecting portions 111 are provided on the first bottom plate 11, and four corresponding connecting portions 111 are also provided on the second bottom plate 12. A rotating connecting member 30 is rotatably connected to the connecting portions 111 of the first bottom plate 11 and the second bottom plate 12 respectively. Specifically, for the connecting portions 111 at corresponding positions on the first bottom plate 11 and the second bottom plate 12, the receiving grooves 114 thereof communicate with each other. The rotating columns 31 at both ends of the rotating connecting member 30 are rotatably connected to the positioning grooves 113 of the positioning plates 112 on both sides of the receiving groove 114. The plate-like structure 32 of the rotating connecting member 30 is partially located in the receiving groove 114 of the first bottom plate 11, and the other part of the structure is located in the receiving groove 114 of the second bottom plate 12, so that the first bottom plate 11 and the second bottom plate 12 are connected and can be folded relative to each other. The width of the plate-like structure 32 of the rotating connecting portion 111 is basically the same as the total thickness when the first bottom plate 11 and the second bottom plate 12 are in contact at the bottom, so that the folded first bottom plate 11 and second bottom plate 12 are basically rectangular parallelepipeds.

[0051] The positioning groove 113 includes an arc-shaped groove 1131 and a straight opening 1132, and the diameter of the arc-shaped groove 1131 is larger than the width of the straight opening 1132. Correspondingly, rotating columns 31 are provided at both ends of the rotating connecting member 30, and the size is adapted to the arc surface of the positioning groove 113. After the rotating column 31 is snapped into the arc-shaped groove 1131, restricted by the smaller-sized straight opening 1132, the rotating column 31 is not easily disengaged from the positioning groove 113 and can rotate normally in the arc-shaped groove 1131.

[0052] As shown in the appendix Figure 1 and the appendix Figure 5As shown, in order to meet the requirements of different forms of abdominal exercises, the sliding devices 50 of this embodiment slide correspondingly with a group of tracks, and there are two groups of sliding devices 50. When the multifunctional abdominal exercise board of this embodiment is in use, each group of sliding devices 50 corresponds to one hand or one leg of the trainer; a detachable connection component 53 is provided between the two groups of sliding devices 50. The connection component 53 includes an extension tube 531, a connecting rod 532, a spring 533 and a locking member 534. The extension tube 531 is located on the opposite surfaces of the two sliding devices 50. The two ends of the connecting rod 532 are inserted into the two extension tubes 531 to connect the two extension tubes 531; the spring 533 is located in one of the extension tubes 531, with one end abutting against one end of the connecting rod 532 and the other end abutting against the inner wall of the extension tube 531. Two locking grooves 535 arranged at intervals and a moving groove 536 communicating the two locking grooves 535 are provided on the side surface of this extension tube 531. The locking member 534 is fixed at one end of the connecting rod 532. The connecting rod 532 can rotate and move in the extension tube 531. The locking member 534 is a locking rod. When it is necessary to connect the two sliding devices 50, hold the locking rod and rotate the connecting rod 532 so that the locking rod moves from one locking groove 535 far from the other extension tube 531 to the moving groove 536. At this time, the spring 533 is in a compressed state, applying a thrust to the connecting rod 532, so that the connecting rod 532 moves towards the other extension tube 531 and is inserted. At the same time, the locking rod moves in the moving groove 536. When the locking rod corresponds to the position of the locking groove 535 close to the other extension tube 531, hold the locking rod again and rotate the connecting rod 532 so that the locking rod is snapped into this locking groove 535. The two groups of sliding devices 50 are in a connected state and can move uniformly when the trainer exercises.

[0053] As shown in the attached Figure 1 and attached Figure 3 As shown, each group of sliding devices 50 includes a support portion 54 and a handle 55. The handle 55 is detachably connected to the support portion 54. When the trainer is used for abdominal exercises dominated by the legs, the handle 55 is not connected to the support portion 54; when the trainer is used for abdominal exercises dominated by the hands, the handle 55 is connected to the handle mounting hole 545 and fixed on the support portion 54 for the trainer to hold. The support portion 54 in this embodiment includes a first placement portion 541 and a second placement portion 542, and the two are of an integral structure. The surface of the first placement portion 541 has a ring of convex edges 543, and an accommodation groove is formed inside the convex edges 543. A contact pad 544 is installed in the accommodation groove; when the trainer is used for abdominal exercises dominated by the legs, the trainer can kneel on the contact pad 544 with the knees, thereby protecting the knees. At the same time, place the calves on the second placement portion 542 to play a supporting role and facilitate the trainer's force application action; when the trainer is used for abdominal exercises dominated by the hands, the trainer can place the elbows on the contact pad 544, place the forearms on the second placement portion 542, and hold the handle 55. While performing abdominal exercises, it is also convenient for the elbow joint to apply force and reduce the burden on the forearms.

[0054] The acting surface of the first placing part 541 is not lower than the highest surface of the second placing part 542, that is, the upper surface of the contact pad 544 is higher than or flush with the upper surface of the second placing part 542, so that when doing sit-up exercises, the forearm or calf is inclined relative to the first placing part 541 when it fits with the second placing part 542, making the elbow joint or knee the main force-bearing point and facilitating the application of force during sit-up exercises.

[0055] Preferably, in this embodiment, the end of the second placing part 542 connected to the first placing part 541 is the large end part, and the end far from the first placing part 541 is the small end part. The width of the second placing part 542 gradually decreases from the large end part to the small end part; the width of the first placing part 541 is greater than or equal to the width of the large end part; this makes the bearing area of the supporting part 54 larger, improves the stability of the forearm or calf or buttocks or back on the sliding device 50. Both the first placing part 541 and the second placing part 542 can include soft materials laid on their surfaces to improve comfort. In addition, various matching patterns can be set on the upper surfaces of the first placing part 541 and the second placing part 542 to play an indicating role.

[0056] In some other embodiments, an arc-shaped depression is provided on the upper surface of the second placing part 542. The arc-shaped depression extends along the length direction of the bottom plate 10 and is adapted to the shape of the forearm or calf to further improve the stability of the forearm or calf on the sliding device 50.

[0057] As shown in the appendix Figure 4 In this embodiment, as shown, the handle 55 includes a rigid column body 551 inside and a soft coating layer 552 sleeved on the rigid column body 551, so that the handle 55 has both supportiveness and a good touch. A limit protrusion 553 is provided at the bottom of the handle. A limit port 546 and a limit wall 547 are provided in the handle mounting hole 545. The limit port 546 is adapted to the limit protrusion 553, so that the bottom of the handle 55 can be inserted into the handle mounting hole 545 and rotate relative to the handle mounting hole 545. After rotation, the limit protrusion 553 is located below the limit wall 547, so that the handle 55 is clamped with the handle mounting hole 545.

[0058] Two handle mounting holes 545 are provided on the second placing part 542, and the two handle mounting holes 545 are spaced apart along the length direction of the bottom plate 10. The user can install the handle in the corresponding handle mounting hole 545 according to his own arm length. It should be noted that in this embodiment, the connection angle between the handle 55 and the handle mounting hole 545 can be 90°; in other embodiments, the connection angle between the handle 55 and the handle mounting hole 545 can be less than 90°, so that the handle 55 is inclined relative to the supporting part 54, and the range of the connection angle is 60° - 90°.

[0059] During the abdominal exercise, the sliding device 50 requires some resilience so that the sliding device 50 can automatically reset, or the trainer needs to apply more force to move the sliding device 50, thereby increasing the training difficulty. Therefore, as shown in Figure 2 and Figure 6 shown, elastic ropes 56 and two elastic rope fixing members 57 are provided at the bottom of the bottom plate 10. The two elastic rope fixing members 57 are respectively connected to both ends of the elastic rope 56. One of the elastic rope fixing members 57 is detachably connected to the sliding device 50, and the other elastic rope fixing member 57 is detachably connected to the bottom plate 10. The initial position of the sliding device 50 is close to one end of the bottom plate 10. The trainer moves the sliding device 50 towards the middle of the bottom plate 10, thereby stretching the elastic rope 56. The elastic rope 56 exerts a resilience on the sliding device 50. After the trainer withdraws the applied force, the sliding device 50 drives the trainer to reset. If the trainer needs to increase the training difficulty, the tightness of the screws at both ends of the elastic rope fixing member can be adjusted. By changing the pressure of the elastic rope fixing member on the elastic rope and changing the aperture inside the elastic rope 56, when the thread is tightened more, the tensile force of the elastic rope 56 is greater, and the force applied by the trainer during training is also greater. Or the elastic rope fixing member can be disassembled, and the resilience can be changed by replacing the elastic rope with other apertures or adjusting the actual acting length of the elastic rope.

[0060] A fixed pulley 58 is also provided at the bottom of the bottom plate 10 of this embodiment. One end of the elastic rope 56 is connected to the bottom plate 10 through an elastic rope fixing member, and the other end passes around the fixed pulley 58 and is connected to the sliding device 50 through another elastic rope fixing member. Thus, without changing the length of the bottom plate 10, the length of the elastic rope 56 can be longer, thereby providing a larger adjustment space to meet the training requirements at different stages.

[0061] Corresponding to the push-up function of the multi-functional abdominal board, there are numerous handle fixing holes 13 on the bottom plate 10 and they are distributed in groups. Specifically, as shown in Figure 7As shown in the figure, a number of handle fixing holes 13 on the first bottom plate 11 and the second bottom plate 12 are symmetrically arranged with the folding line 16 as the axis of symmetry. The number of handle fixing holes 13 includes several groups of mounting positions perpendicular to the length direction of the bottom plate, at least one group of mounting positions parallel to the length direction of the bottom plate 10, and at least one group of mounting positions distributed in a triangular shape; the distance between the handle fixing holes 13 in each group of mounting positions is adapted to the distance of the positioning protrusions 23 of the push-up handle 20. In this embodiment, there are three groups of mounting positions perpendicular to the length direction of the bottom plate 10, and each mounting position includes two handle fixing holes 13 whose distances are adapted to the distance of the positioning protrusions 23 of the push-up handle 20; one group of mounting positions parallel to the length direction of the bottom plate 10, that is, two handle fixing holes 13 whose distances are adapted to the distance of the positioning protrusions 23 of the push-up handle 20 are arranged along the length direction of the bottom plate 10; one group of mounting positions distributed in a triangular shape, including three handle fixing holes 13, which are distributed in an equilateral triangle, and the side length is equal to the distance of the positioning protrusions 23 of the push-up handle 20. The handle fixing holes 13 in each group of mounting positions are marked with the same color, and the colors of the handle fixing holes 13 in different groups are different, so as to guide the trainer to insert the push-up handle 20 into the corresponding handle fixing holes 13.

[0062] Since when doing push-ups, the force exerted by the trainer on the push-up handle 20 and the bottom plate 10 always remains downward, the handle fixing holes 13 can be round holes, as shown in the appendix Figure 2 As shown, the corresponding positioning protrusions 23 of the push-up handle 20 can be cylinders, and the cylinders are adaptively inserted into the round holes. Generally, the push-up handle 20 has two positioning protrusions 23, which respectively correspond to two handle fixing holes 13. Therefore, after the push-up handle 20 is fixed on the bottom plate 10, it is not easy to shake, which is beneficial to keeping the push-up handle 20 stable during training.

[0063] Of course, in other embodiments, the push-up handle 20 and the handle fixing holes 13 can also be magnetically attracted; or other conventional plug-in and unplug settings.

[0064] As shown in the appendix Figure 2 As shown, in order to facilitate the storage of the push-up handle 20, the bottom of the bottom plate 10 has a concave structure 14. The concave structure 14 has a convex structure 15 corresponding to the handle fixing holes 13. The concave structure 14 has a placement area 141 for accommodating the push-up handle 20. There is a convex structure 15 in the placement area 141. The push-up handle 20 has a hollow part 22. The outer diameter of the convex structure 15 is less than or equal to the size of the hollow part 22 of the push-up handle 20, so that when the push-up handle 20 is placed in the placement area 141, the convex structure 15 passes through the hollow part 22.

[0065] Since the base plate 10 of the present embodiment is formed by connecting the first base plate 11 and the second base plate 12, when the base plate 10 is folded, the recessed structure 14 forms a space for accommodating the push-up handles 20 and other accessories. Therefore, the depth of the recessed structure 14 is greater than or equal to one half of the push-up handles 20. Therefore, when the bottoms of the first base plate 11 and the second base plate 12 are closed, the push-up handles 20 can be completely stored, and due to the cooperation of the placement area 141 and the protruding structure 15, the push-up handles 20 will not shake between the first base plate 11 and the second base plate 12.

[0066] Specifically, the edge of the placement area 141 has a convex strip 142 that matches the shape of the push-up handle 20. The height of the convex strip 142 is less than the depth of the recessed structure 14, which can play a role in limiting the push-up handle 20 and also play an indicating role.

[0067] Furthermore, a receiving plate 143 corresponding to the gripping portion 21 of the push-up handle 20 is provided in the placement area 141, and an arc-shaped groove 144 is provided on the receiving plate 143, and the gripping portion 21 is placed thereon. When the first bottom plate 11 and the second bottom plate 12 are closed, the two receiving portions clamp the gripping portion 21 of the push-up handle 20, further fixing the push-up handle 20 and preventing the push-up handle 20 from shaking.

[0068] In this embodiment, as shown in the attached Figure 2 As shown, the bottom surface of the raised structure 15 is flush with the bottom surface of the base plate 10, that is, when the base plate 10 is unfolded for use, the bottom surface of the raised structure 15 is also in contact with the plane. Therefore, the bottom surface of the raised structure 15 is provided with an anti-skid pad 151, which plays an anti-skid role and prevents the base plate 10 from sliding during training, and has better stability. The anti-skid pad 151 is set on the raised structure 15, and the raised structure 15 corresponds to the handle fixing hole 13. The inner wall of the handle fixing hole 13 itself also needs to extend to the bottom of the base plate 10. Therefore, the combination of the two simplifies the structure of the base plate 10, and there is no need to set an additional fixing structure, which reduces the difficulty of processing and reduces the material used, saving costs. The anti-skid pad 151 can be a conventional setting, using anti-skid protrusions and anti-skid materials, such as rubber.

[0069] In this embodiment, as shown in the attached Figure 1 As shown, a timer 40 or a counter can be embedded in the first bottom plate 11 and the second bottom plate 12 respectively.

When the timer 40 or the counter is not needed, the locking hole 115 can be covered with a cover plate 41, which fully takes into account the production and manufacturing and the personalized needs of consumers.

[0070] As shown in the attached Figure 1 figure, in this embodiment, through grooves 116 are provided at the ends of the first bottom plate 11 and the second bottom plate 12 that are relatively far away from each other. When the first bottom plate 11 and the second bottom plate 12 are folded relative to each other, the two through grooves 116 are opposite and communicate with each other to form a carrying opening. The carrying opening and the rotating connecting member 30 are respectively located at both ends of the folded bottom plate, so that a stable accommodating space is formed inside the folded bottom plate to accommodate the push-up handle 20 and other accessories and is not easily detached; the carrying opening facilitates the trainer to pick up or carry the folded trainer.

[0071] As shown in the attached Figure 1 figure, a mobile phone holder 17 is further provided on both sides of the through hole respectively. The mobile phone holder 17 is rotatably connected to the bottom plate 10. The mobile phone holder 17 can be used to place display devices such as tablets or mobile phones, so that the trainer can train along with the video, improving the training effect. Since the mobile phone holders 17 are provided at both ends of the bottom plate 10 in the length direction, the trainer can set a sliding device 50 at one end of the bottom plate 10 and place a mobile phone on the mobile phone holder 17 at the other end.

[0072] As shown in the attached Figure 8 and attached Figure 9 figure, the multi-functional abdominal exercise board according to another embodiment of the present invention further includes a Pilates structure.
