[0004] The purpose of the utility model is to provide a fitness device with strong stability and high functionality.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] A fitness device, characterized in that it includes a plate-like base, a support component and a power-assisting mechanism, wherein the support component can be slidably arranged on the plate-like base forward and backward, and the power-assisting mechanism includes an elastic member, which is connected to the support component and is configured so that when the support component slides forward, the elastic member deforms and stores force, and when the support component slides backward, the elastic member provides power-assisting assistance, so that when exercising, the user can support the upper limbs on the support component and drive the support component to slide forward and backward on the plate-like base to perform abdominal exercises, and can also support the lower limbs on the support component to slide forward and backward to achieve a multifunctional exercise effect. Because the support component is arranged on the plate-like base, the sliding trajectory is relatively fixed, so the exercise stability is higher.

[0007] The support component includes two support parts spaced apart on the left and right sides, and the plate-shaped base is provided with two slide rails extending forward and backward. The two support parts can better achieve the support effect, and the two support parts are respectively slidably matched with the two slide rails. The two slide rails can limit the two support parts from moving laterally, thereby further increasing the stability of exercise.

[0008] The slide rail is a groove structure extending forward and backward, and a sliding pad is laid at the bottom of the groove. The bottom of the support part slides with the sliding pad. The provision of the sliding pad can reduce the friction between the support part and the slide rail, making the exercise smoother, and improve the wear resistance of the support part and the slide rail, and extend the service life.

[0009] Rollers that roll with the groove wall of the groove are respectively arranged on both sides of the support part. The rollers can prevent the two ends of the support part from having too much friction with the groove wall of the groove, making the support part slide more smoothly and extending its service life.

[0010] The sliding pad comprises a flexible polymer layer, and the bottom of the support portion is slidably matched with the flexible polymer layer.

[0011] The two support parts are detachably connected to each other through a connecting structure, so that the two support parts can slide forward and backward at the same time through the connecting structure, or the two support parts can slide forward and backward alternately after detachment, or only one support part can be used to slide forward and backward, which can be switched according to the user's needs.

[0012] The connecting structure includes a connecting pipe and two plug-in pipes arranged on the two supporting parts. The connecting pipe is plugged between the two plug-in pipes. An elastic button that can float up and down is arranged at the end of the connecting pipe. A connecting hole that cooperates with the elastic button is opened on the groove wall of the plug-in pipe. After the connecting pipe is inserted into the plug-in pipe, the elastic button cooperates with the connecting hole to limit the connection pipe from being separated from the plug-in pipe, so that it can be quickly plugged in or disassembled, which is convenient to use.

[0013] The plate-like base includes two plates connected to each other in a rotatable manner. The two plates can be rotated between an unfolded state in which the front and back are laid flat and a folded state in which they overlap each other. When needed, the two plates only need to be rotated to the unfolded state. After use, the two plates can be rotated to the folded state for storage.

[0014] The power-assisting mechanism includes the elastic member and a plurality of guide wheels, wherein the elastic member is an elastic rope connected between the two support parts, and the plurality of guide wheels are rotatably arranged on the plate-like base, and the elastic rope is tensioned between the plurality of guide wheels, and the end of the elastic rope used for guiding can be pulled by the support part along the length direction of the slide rail, so that the elastic rope can be well guided into the slide rail without friction with the slide rail, and the use is smoother and the service life is extended, and the two support parts will also be subjected to the mutual force due to the elastic rope.

[0015] The multiple guide wheels include two first guide wheels, two second guide wheels and two third guide wheels, the two first guide wheels are located between the two slide rails and are arranged at intervals on the left and right, the two second guide wheels are respectively arranged opposite to the rear ends of the two slide rails, the two third guide wheels are located between the two second guide wheels and are arranged at intervals on the left and right, the two first guide wheels are supported on the inner side of the elastic rope, the two third guide wheels and the two second guide wheels are supported on the outer side of the elastic rope, the two first guide wheels, the two third guide wheels and the two second guide wheels can cooperate to tension the elastic rope on the plate-like base, and because the two first guide wheels are supported on the inner side of the elastic rope, the two third guide wheels and the two second guide wheels are supported on the outer side of the elastic rope, the elastic rope can be effectively prevented from detaching.

[0016] The two support parts are provided with cushioning pads, and the front ends of the two support parts are provided with armrests.

[0029] Reference Figures 1 to 12 As shown, a fitness device includes a plate-shaped base 1, a supporting component and a power-assisting mechanism. The plate-shaped base 1 includes a first plate body 11 and a second plate body 12 that are rotatably connected to each other. The first plate body 11 and the second plate body 12 are rotatably connected to each other by a hinge. The first plate body 11 and the second plate body 12 can be rotated between an unfolded state in which the plate bodies are laid flat front and back and a folded state in which the plate bodies overlap each other. When the two plates are needed, they only need to be rotated to the unfolded state. After use, the first plate body 11 and the second plate body 12 can be rotated to the folded state for storage. The first plate body 11 includes a first upper shell 111 and a first lower shell 112 that can be buckled together. The second plate body 12 includes a second upper shell 121 and a second lower shell 122 that can be buckled together. The power-assisting mechanism is arranged between the first upper shell 111 and the second lower shell 122. Two grooves that are symmetrical and extend front and back are formed at both ends of the plate-shaped base 1. The two grooves are slide rails 13. A sliding pad 131 is laid at the bottom of the groove, and the sliding pad 131 is a flexible polymer layer. The flexible polymer layer can be made of polytetrafluoroethylene, polyethylene, polypropylene, polycarbonate or a combination of these materials. The specific details are not limited here. The products made of the above materials have the advantage of a small friction coefficient. The supporting component includes two supporting parts 2 arranged at intervals on the left and right. The two supporting parts 2 are arranged on a plate-like base 1, and the two supporting parts 2 can be arranged on the slide rail 13 to slide back and forth. The two grooves include two groove walls and a bottom wall. The groove walls can limit the two supporting parts 2 from moving laterally, which can increase the stability of exercise, and the bottom of the two supporting parts 2 is provided with a wear-resistant layer 27 that slides with the sliding pad 131. The wear-resistant layer 27 can cooperate with the sliding pad 131 to further reduce the friction coefficient between the supporting part 2 and the slide rail 13, making the exercise smoother, and improving the wear resistance of the supporting part 2 and the slide rail 13, and extending the service life.

[0030] The power-assisting mechanism includes an elastic member and a plurality of guide wheels. The elastic member is an elastic rope 3. Both ends of the elastic rope 3 are connected to the two support parts 2. When the support part slides forward, the elastic rope 3 is stretched and deformed to store force, and when the support part slides backward, the elastic rope 3 provides power assistance. In this way, the user can do abdominal exercises or other exercises on the plate-like base 1 through the support part during exercise. Because the support part is arranged on the plate-like base 1, the exercise has high stability. The plurality of guide wheels are rotatably arranged on the plate-like base 1. The elastic rope 3 is tensioned between the plurality of guide wheels to guide the ends of the elastic rope 3. The support part 2 can be pulled along the length direction of the slide rail 13, so that the elastic rope 3 can be well guided into the slide rail 13 without rubbing against the slide rail 13, which makes it smoother to use and extends the service life. The guide wheel is arranged between the first upper shell 111 and the first lower shell 112. During installation, the guide wheel is first fixed to the first lower shell 112, and then the elastic rope 3 is passed through multiple guide wheels in turn to connect with the two support parts 2, and finally the first upper shell 111 is covered. In this way, the guide wheel and the elastic rope 3 can be hidden between the first upper shell 111 and the first lower shell 112, making them less likely to be damaged.

[0031] The plurality of guide wheels include two first guide wheels 41, two second guide wheels 42 and two third guide wheels 43. The two first guide wheels 41 are located between the two slide rails 13 and are arranged at intervals on the left and right. The two second guide wheels 42 are arranged opposite to the rear ends of the two slide rails 13 respectively. The two third guide wheels 43 are located between the two second guide wheels 42 and are arranged at intervals on the left and right. The two first guide wheels 41 are supported on the inner side of the elastic rope 3, and the two third guide wheels 43 and the two second guide wheels 42 are supported on the outer side of the elastic rope 3. Figures 6 to 8 As shown, the two first guide wheels 41 and the two third guide wheels 43 are arranged in a parallelogram, so that the two first guide wheels 41, the two third guide wheels 43 and the two second guide wheels 42 can cooperate to tension the elastic rope 3 on the plate-like base, and because the two first guide wheels 41 are supported on the inner side of the elastic rope 3, and the two third guide wheels 43 and the two second guide wheels 42 are supported on the outer side of the elastic rope 3, the elastic rope 3 can be effectively prevented from detaching from the two first guide wheels 41, the two second guide wheels 42 and the two third guide wheels 43.

[0032] The support part 2 is a hollow structure, and a connecting notch 21 is formed at the rear end of the support part 2. The connecting notch 21 includes a guide section 211, a limit section 212 and a connecting section 213 connected in sequence from top to bottom. Both ends of the guide section 211 extend outward in an arc shape, and the limit section 212 is connected between the guide section 211 and the connecting section 213. The connecting section 213 is a circle with a diameter equivalent to the diameter of the elastic rope 3. The elastic rope 3 is tubular, and both ends of the elastic rope 3 are sleeved with anti-slipping parts 31. The anti-slipping parts 31 are spherical, specifically wooden plugs. The diameter of the anti-slipping parts 31 is larger than the diameter of the elastic rope 3 and larger than the limit section 2. 12 and the diameter of the connecting section 213. During installation, the elastic cord 3 is pressed downward from the guide section 211 of the connecting notch 21 into the limiting section 212. At this time, the elastic cord 3 is squeezed by the two ends of the limiting section 212 and continues to be pressed down until the elastic cord 3 is embedded in the connecting section 213. The squeezed elastic cord 3 is elastically reset. In this way, the limiting section 212 can block the elastic cord 3 from moving upward and prevent the elastic cord 3 from escaping from the limiting notch from the upper end, and the anti-slip component 31 can be blocked by the connecting section 213. When the user uses the support part 2 to slide back and forth, stretching the elastic cord 3 will not cause the elastic cord 3 to slip out of the rear end of the support part 2.

[0033] Rollers 23 are respectively arranged on both sides of the two support parts 2 to roll with the groove wall of the groove. The rollers 23 can prevent the two ends of the support part 2 from having too much friction with the groove wall of the groove, making the support part 2 slide more smoothly and extending the service life.

[0034] The two support parts 2 are detachably connected to each other through a connecting structure, so that the two support parts 2 can slide forward and backward at the same time, or the two support parts 2 can slide forward and backward alternately after being disassembled, or only one support part 2 can slide forward and backward, which can be switched according to the needs of the user. The connecting structure includes a connecting pipe 25 and two plug-in pipes 22 arranged on the two support parts 2. The connecting pipe 25 is plugged between the two plug-in pipes 22. The right end of the connecting pipe 25 is provided with an elastic button 251 that can float up and down. The groove wall of the plug-in pipe 22 on the right side is provided with a spring that can float up and down. The elastic button 251 cooperates with the connecting hole 221. After the connecting tube 25 is inserted into the plug-in tube 22, the elastic button 251 cooperates with the connecting hole 221 to limit the connection tube 25 from being separated from the plug-in tube 22, and the plug-in tube 22 on the left can accommodate the connection tube 25 to continue to be inserted inward. When disassembly is required, just press the elastic button 251, and then continue to insert the left end of the connecting tube 25 into the plug-in tube 22 on the left, the right end of the connecting tube 25 can be separated from the plug-in tube 22 on the right, and the two supporting parts 2 can be separated, so that it can be quickly plugged in or disassembled, which is convenient to use.

[0035] The bottom of the plate-like base 1 is paved with an anti-skid pad 14, which can increase the friction between the plate-like base 1 and the bottom plate to prevent the plate-like base 1 from sliding relative to the ground when the user operates the support part 2 to slide back and forth. The top surface of the support part 2 is paved with a buffer pad 26, which can allow the user's elbows to be supported on the support part 2 during exercise, which is more comfortable. An armrest 24 is provided at the front end of the support part 2 for the user to grasp, making the movement more stable. The armrest 24 is rotatably connected to the support part 2. After the plate-like base 1 is rotated to a folded state, the armrest 24 can also be rotated to an easily retractable state.

[0036] The utility model can realize a variety of different exercise methods: the user kneels, bends over and places the elbow on the support part 2, holds the armrest 24, operates the two support parts 2 to slide forward and backward at the same time, performs abdominal exercises, or slides the two support parts 2 back and forth alternately, and exercises the side abdominal muscles; the user lies prone with his back to the plate-like base, places the feet on the support part 2, operates the two support parts 2 to slide forward and backward at the same time, or slides back and forth alternately, to exercise the abdominal muscles; one hand is placed on one support part 2, and the other leg kneels on one knee, with one hand and one foot as support points, and the other hand and leg are stretched out to maintain balance, so as to exercise the hand and leg muscles. A variety of different exercise effects can be achieved according to the needs of the user.

[0037] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
