Description

Technical Field

[0001] This invention belongs to the field of fitness equipment technology, and in particular relates to a combination training device. Background Technology

[0002] Trampolines, as a type of exercise equipment that effectively improves cardiovascular function, promotes metabolism, and enhances physical coordination, are popular among consumers. Existing trampoline training equipment, such as the multifunctional trampoline disclosed in Chinese utility model patent CN222841468U, enriches training functions to some extent, for example by adding elastic resistance bar handrails and stretching auxiliary handles to the main frame of the trampoline to provide simple limb exercises.

[0003] However, when performing stretching exercises, users need to stand directly on the elastic trampoline cloth. Because the trampoline cloth itself is elastic and soft, it is unstable when standing, which can easily lead to falls or sprains due to instability, posing a significant safety hazard. Secondly, when performing stretching exercises, the trampoline cloth connecting frame can only be placed horizontally or fixed to a single angle with the main frame. It cannot flexibly adjust the angle of the training platform according to the user's height, flexibility, or the needs of different stretching exercises, thus limiting its functionality and applicability for stretching training. Summary of the Invention

[0004] The purpose of this invention is to provide a combined training device to solve the technical problems of existing trampoline training devices having safety hazards and being unable to adjust the training angle when performing stretching and extension training.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a combined training device, including a support frame and a handrail unit detachably disposed on one side of the support frame. A flipping platform assembly is installed on the support frame. The flipping platform assembly includes an outer frame and an inner frame movably connected to the outer frame. Trampoline units and stretching units are respectively provided on opposite sides of the inner frame. By flipping the inner frame, a first training mode with the trampoline units facing upward or a second training mode with the stretching units facing upward can be switched.

[0006] Preferably, the outer frame has an adjustment slot, and the inner frame is movably disposed in the adjustment slot. The adjustment slot has a first position for fixing the inner frame and a second position for flipping the inner frame. A movable groove is provided between the first position and the second position, and the two sides of the inner frame have protrusions that slide in cooperation with the movable groove.

[0007] Preferably, the front side of the inner frame is provided with a plurality of positioning parts, and the side wall opposite to the positioning parts of the adjustment slot is provided with positioning openings corresponding to the number of positioning parts. When the inner frame is in the first position, the positioning parts extend into the positioning openings.

[0008] Preferably, a fixing plate is hinged to the side of the inner frame away from the positioning part, and a locking mechanism is provided between the fixing plate and the inner frame. The fixing plate has an unfolded state and a folded state. In the first training mode, the fixing plate is locked in the folded state by the locking mechanism. In the second training mode, the fixing plate is locked in the unfolded state by the locking mechanism.

[0009] Preferably, the supporting frame has a clearance groove at the entrance of the adjustment slot, and a slot is provided on the bottom wall of the clearance groove. The fixing plate is provided with a plug that matches the slot. When the inner frame is in the first position, the fixing plate is in a folded state and the plug is inserted into the slot.

[0010] Preferably, a rod receiving groove is provided on one side of the fixing plate, and a rod is rotatably disposed in the rod receiving groove.

[0011] Preferably, the inner frame has a hollow structure to form an interval space between the trampoline unit and the bracing unit, allowing the trampoline unit to bounce.

[0012] Preferably, the handrail unit includes a handrail base and a handrail frame mounted on the handrail base. A limiting plate is provided on the upper surface of the handrail base near the supporting frame. The limiting plate has a plurality of support grooves sequentially extended along its lateral direction. When the fixing plate is in the unfolded state, the abutment rod can rotate downward and cooperate with the support groove to limit the position, so as to support the inner frame adjusted to the required angle.

[0013] Preferably, it further includes at least two sets of support units, each support unit including a support base plate detachably connected to the bearing frame, and a support frame fixed to the upper surface of the support base plate, the support frame being provided with a handrail and a tension rope unit for performing stretching movements.

[0014] Preferably, the trampoline unit includes a trampoline frame mounted on the inner frame and a trampoline cloth disposed within the trampoline frame by an elastic element. The bracing unit includes a plate disposed on the side of the inner frame away from the trampoline frame, and the surface of the plate is provided with anti-slip texture.

[0015] Compared with existing technologies, the present invention has the following advantages through the above technical solution: By setting a switchable flipping platform component, which includes an inner frame that can slide and flip along an adjustment slot, and trampoline units and stretching units are respectively set on opposite sides of the inner frame. In actual use, users can, according to their own training needs, use simple pushing, pulling and flipping operations to make the trampoline unit face upwards for trampoline exercise, or make the stretching unit face upwards for stretching training. The two modes are independent and easy to switch. The stretching unit uses a rigid plate with anti-slip texture on its surface. When users perform stretching training, they stand on a stable, flat, rigid surface, rather than on an elastic trampoline cloth, thus solving the safety hazards caused by standing on an elastic cloth surface for stretching in existing technologies, and ensuring stability and safety during training.

[0016] Meanwhile, by installing a rotatable abutment rod on the fixed plate and a limiting plate with multiple support slots on the handrail base, the engagement between the abutment rod and the support slots adopts a multi-level adjustable structure. In actual use, when the user switches the flip platform assembly to the second training mode with the stretching unit facing upwards, the fixed plate can be unfolded, and the abutment rod can be inserted into different support slots according to the user's waist flexibility, height, and the specific stretching areas required, thereby achieving multi-level adjustment of the stretching unit's tilt angle. This adjustment method is simple to operate, reliable in positioning, and improves the targeting and effectiveness of stretching training, solving the technical problem of existing trampoline trainers being unable to adjust the training angle. Finally, by installing detachable support units on the support frame, in actual use, users can assemble the support units to both sides of the support frame as needed, using the tension rope units for various upper limb strength training exercises such as rowing, chest expansion, and bicep curls, while the handrails provide additional grip support. This structure further integrates strength training functions into the trainer, building upon its trampoline and stretching capabilities. Attached Figure Description

Detailed Implementation

[0019] The following will refer to the appendices in the embodiments of the present invention. Figure 1-11 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0021] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0022] like Figure 1-11 As shown: A combined training device includes a support frame 1 and a detachable handrail unit 3 mounted on one side of the support frame 1. The support frame 1 is a square frame structure made of welded metal tubing and is used to support the main body of the entire training device. The handrail unit 3 is used to provide auxiliary support when the user performs stretching exercises. A flipping platform assembly 2 is installed on the support frame 1. The flipping platform assembly 2 includes an outer frame 201 and an inner frame 200 movably connected to the outer frame 201. Trampoline units 202 and stretching units 203 are respectively provided on opposite sides of the inner frame 200. By flipping the inner frame 200, the user can switch between a first training mode (trampoline mode) with the trampoline unit 202 facing upwards, or a second training mode (stretching mode) with the stretching unit 203 facing upwards. This structural design integrates two training functions on the same platform, allowing the user to switch freely according to their training needs.

[0023] like Figure 7As shown: An adjustment slot 204 is provided on the outer frame 201. The adjustment slot 204 has a U-shaped or rectangular opening structure. The inner frame 200 is movably disposed within the adjustment slot 204 to achieve smooth movement and reliable flipping of the inner frame 200 within the outer frame 201. Specifically, the adjustment slot 204 has a first position for fixing the inner frame 200 and a second position for flipping the inner frame 200. The first position is located at the front end of the adjustment slot 204, near the handrail unit 3, and the second position is located at the rear end of the adjustment slot 204, away from the handrail unit 3. A movable groove 205 is provided between the first and second positions, extending along the length of the adjustment slot 204. The inner frame 200 has protrusions, such as cylindrical sliders or rollers, on both sides that slide in conjunction with the movable groove 205. The cooperation between the protrusions and the movable groove 205 forms a guide structure, ensuring that the inner frame 200 maintains a straight line during forward and backward movement, preventing skewing or jamming. Meanwhile, the length of the movable slot 205 limits the travel of the inner frame 200, ensuring it can accurately reach the first or second position. This sliding guide structure makes mode switching operations smoother and less strenuous, and improves the positioning accuracy of the inner frame 200 during movement. During use, the inner frame 200 must be pulled out before it can be rotated, i.e., moved from the first position to the second position, ensuring the stability and safety of the inner frame 200 when in the first position.

[0024] like Figure 7 and Figure 9 As shown: The front side of the inner frame 200 is provided with several positioning parts 206. Each positioning part 206 is a cylindrical positioning post, and its front end can be set to a hemispherical or conical shape to facilitate insertion. On the side wall opposite to the positioning parts 206, the adjusting slot 204 has positioning openings 207 corresponding to the number of positioning parts 206. The positioning openings 207 are circular or elliptical holes matching the shape of the positioning parts 206. When the inner frame 200 is in the first position, the positioning parts 206 extend into the positioning openings 207, forming a plug-in fit, thereby reliably locking the inner frame 200 in the horizontal direction and preventing it from sliding backward or accidentally flipping during training due to force. This positioning and locking structure adopts a mechanical plug-in method, featuring simple structure, reliable locking, and convenient unlocking. When switching modes is required, simply pushing the inner frame 200 backward will disengage the positioning parts 206 from the positioning openings 207, achieving quick unlocking without the need for any tools.

[0025] like Figure 6-11As shown: A fixed plate 208 is hinged to the side of the inner frame 200 away from the positioning part 206, i.e., the rear side of the inner frame 200, via a hinge structure. A locking mechanism is provided between the fixed plate 208 and the inner frame 200. In this embodiment, the locking mechanism is a rotary lock. Specifically, the locking mechanism may include a latch on the fixed plate and a lock hole on the inner frame. The latch is extended or retracted by pressing a button to lock and unlock the fixed plate and the inner frame in either the unfolded or folded state. The fixed plate 208 has two working states: unfolded and folded. In the first training mode, i.e., when the trampoline unit 202 faces upwards and downwards... Figure 5 As shown, the fixing plate 208 is locked in a folded state by a locking mechanism. At this time, the fixing plate 208 is flush against the bottom surface of the inner frame 200, completely avoiding the jumping space below the trampoline unit 202, ensuring that the user will not interfere with the fixing plate 208 when jumping. In the second training mode, the stretching unit 203 faces upwards and downwards... Figure 11 As shown, the fixed plate 208 is locked in the unfolded state by a locking mechanism. At this time, the fixed plate 208 extends outward from the rear side of the inner frame 200, providing a structural basis for subsequent angle adjustment and support. This hinge and locking structure allows the fixed plate 208 to quickly switch forms according to the needs of the training mode.

[0026] like Figure 2 and Figure 9 As shown: To further enhance the stability of the inner frame 200 in the first training mode, a clearance groove 101 is provided at the entrance of the adjustment slot 204 on the support frame 1. This clearance groove 101 is used to accommodate the fixed plate 208 in the folded state. A slot 102 is provided on the bottom wall of the clearance groove 101, and the fixed plate 208 is provided with a plug-in component 209, such as a pin or hook, that matches the slot 102. When the inner frame 200 is in the first position and the fixed plate 208 is in the folded state, the plug-in component 209 is inserted into the slot 102 to form an auxiliary lock. This structure allows the fixed plate 208 to form a plug-in engagement with the support frame 1 in the folded state, effectively preventing the inner frame 200 from undergoing slight displacement or loosening due to severe vibration during trampoline training, further enhancing the rigidity and stability of the overall structure and ensuring the safety of the user when jumping.

[0027] like Figure 7 and Figure 9 As shown: A support rod storage groove 210 is provided on one side of the fixed plate 208. The shape of the storage groove matches the support rod 211. The support rod 211 is rotatably mounted in the support rod storage groove 210 via a pin. The support rod 211 can rotate from 0° to 90° in the storage groove. When not in use, it is completely stored in the support rod storage groove 210, keeping the overall appearance neat and avoiding accidental scratches. The above structure enables multi-level adjustment of the platform angle during stretching training.

[0028] like Figure 1-2as well as Figure 4 As shown: Handrail unit 3 includes handrail base 301 and handrail frame 302 mounted on handrail base 301. Handrail base 301 and supporting frame 1 are detachably fixed by plug-in or bolt connection. A limiting plate 303 is fixedly provided on the upper surface of handrail base 301 near the supporting frame 1. The limiting plate 303 has a plurality of support grooves 304 sequentially formed along its lateral extension direction, i.e., left and right direction. The groove openings of these support grooves 304 face upward and the bottom of the groove is arc-shaped to form a stable fit with the abutment rod 211. There are more than three support grooves 304, each corresponding to a different tilt angle.

[0029] When the fixed plate 208 is in the unfolded state and the tension angle needs to be adjusted, the user lifts the front end of the inner frame 200 upwards, causing the fixed plate 208 to rise to the desired angle. Then, the abutment rod 211 is rotated out of the abutment rod storage slot 210, and its end abuts against the corresponding support slot 304 on the limiting plate 303. The cooperation between the abutment rod 211 and the support slot 304 forms a triangular support structure, stably supporting the inner frame 200 and the tension unit 203 at the desired tilt angle. This multi-position adjustment structure allows users to flexibly choose the most suitable training angle according to their own flexibility, height, and different needs of the stretching parts, improving the pertinence and effectiveness of stretching training.

[0030] The inner frame 200 has a hollow structure to create a space between the trampoline unit 202 and the tensioning unit 203, allowing the trampoline unit 202 to bounce. This hollow structure not only reduces the overall weight of the inner frame 200 and facilitates flipping, but more importantly, it provides sufficient downward deformation space for the trampoline fabric when impacted, ensuring that the trampoline unit 202 can generate sufficient elasticity and guarantee a good jumping experience. At the same time, the hollow structure also provides the inner frame 200 with sufficient structural strength to withstand the impact loads generated by the user during trampoline exercise.

[0031] like Figure 1-2As shown, the system also includes at least two sets of support units 4. Each support unit 4 includes a support base plate 401 detachably connected to the support frame 1, and a support frame 402 fixed to the upper surface of the support base plate 401. The support base plate 401 is installed on the left and right sides of the support frame 1 by bolts, quick-release pins, or magnetic structures, and can be flexibly assembled or disassembled as needed. The support frame 402 is equipped with handrails 403 and resistance rope units 5 for stretching exercises. The resistance rope unit 5 includes an elastic rope and handles. Users can hold the handles with both hands to perform various upper limb resistance training exercises such as rowing, chest expansion, and bicep curls. The handrails 403 provide additional gripping support points to help users stabilize their bodies during strength training. It can also be used as a support for push-ups. The modular design of this support unit 4 allows the trainer to integrate strength training functions in addition to trampoline and stretching functions, expanding the applicability of the equipment.

[0032] The trampoline unit 202 includes a trampoline frame mounted on an inner frame 200 and a trampoline cloth disposed within the trampoline frame via elastic elements such as elastic ropes or metal springs. The trampoline frame is bolted to one side of the inner frame 200, forming a rigid support frame; the trampoline cloth is connected to the trampoline frame around its perimeter via elastic elements, allowing the trampoline cloth to elastically deform under downward pressure, providing an upward rebound force. The stretching unit 203 includes a plate disposed on the side of the inner frame 200 opposite to the trampoline frame. This plate is a rigid plane capable of supporting the weight of the user and will not deform during use. The surface of the plate is provided with anti-slip textures such as diamond embossing, raised dot arrays, or a rubber anti-slip layer to increase friction with the soles of shoes or the body, preventing the user from slipping during stretching and ensuring the safety and stability of stretching movements. This rigid plate structure solves the safety hazards existing in the prior art where users stand on elastic trampoline cloth for stretching training, providing users with a stable and safe stretching platform.

[0033] The invention is used as follows: When used as a trampoline, first ensure that the inner frame 200 is in the first position, the positioning part 206 is inserted into the positioning port 207, and the fixing plate 208 is in a folded state with its connector 209 inserted into the slot 102. At this time, the user can stand on the trampoline unit 202 to perform jumping exercises, and the handrail frame 302 can provide balance assistance.

[0034] When used as a bracing board, pull the positioning part 206 of the inner frame 200 out of the positioning port 207, pull the inner frame 200 outward to the second position, and then flip the inner frame 200 so that the bracing unit 203 faces upward. Then, unfold the fixing plate 208 and lock it through the locking mechanism. Rotate the abutment rod 211 downward from the abutment rod storage slot 210, and insert the abutment rod 211 into the support slot 304 at a suitable position on the handrail unit 3 as needed, thereby supporting the inner frame 200 at the required tilt angle. The user can then stand on the board of the bracing unit 203 to perform leg and waist stretching exercises.

[0035] When other training is required, the support unit 4 is installed onto the load-bearing frame 1. Users can use the handrail 403 to perform bodyweight training such as push-ups, or use the resistance band unit 5 to perform various resistance training exercises to strengthen the upper limbs, back, etc.

[0036] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
