Description

Technical Field

[0001] This invention relates to the field of training equipment technology, specifically a multifunctional fitness instrument. Background Technology

[0002] With societal progress and increased health awareness, fitness is no longer exclusive to a specific group but is gradually becoming integrated into the daily lives of the general public. In recent years, with the economic recovery and the restoration of people's spending power, the scale of China's fitness market has continued to expand.

[0003] Among home fitness equipment, dumbbells, kettlebells, ab wheels, and resistance bands are commonly used because they are convenient to use and easy to store. However, because these types of fitness equipment have limited functions, users who want to practice multiple fitness exercises need to purchase each one separately, and a large number of them will take up a lot of space at home.

[0004] Existing technologies have also proposed integrating some fitness equipment. For example, Chinese patent document CN221732243U discloses a multi-functional fitness equipment that can be used in different combinations to perform kettlebell, dumbbell and barbell exercises. However, its functionality is still very limited and the fitness programs are not rich enough.

[0005] To address the current market gap, the inventor designed a new type of multifunctional fitness device. Summary of the Invention

[0006] To address the technical problems existing in the background art described above, the present invention provides a multifunctional fitness instrument.

[0007] The technical solution of this invention is as follows: A multifunctional fitness device includes a housing, which includes a detachably connected left housing and a right housing, and a coaxial connecting tube is provided on the opposite side of the left housing and the right housing. The upper part of the outer shell is open, and a lifting assembly is provided between the opening and the connecting tube. The lifting assembly includes a tension rope wrapped around the outside of the connecting tube and an outer ring frame on the outside of the upper opening of the outer shell. The lower side of the outer ring frame is connected to the tension rope through an inner arc frame, and the upper side is connected to a handle through a movable connector. When the handle moves upward to the maximum stroke of the movable connector, it can drive the outer ring frame and the inner arc frame to move upward.

[0008] The first counterweight component is detachably connected to each side of the outer shell.

[0009] A side grip assembly is connected inside the connecting tube, with both ends of the side grip assembly extending outside the first counterweight assembly.

[0010] A rotating wheel assembly is detachably connected to the bottom of the outer casing.

[0011] This invention achieves two functions through a detachable first counterweight component: firstly, it allows for the replacement of different weights based on individual physical conditions; secondly, it ensures that the fitness equipment has sufficient weight to maintain stability when performing lifting movements using the lifting component.

[0012] The lifting component of this invention, in conjunction with the added weight of the instrument, allows for repeated upward pulling movements to train the upper limbs. In this mode, the rotating wheel assembly at the bottom of the outer casing needs to be removed.

[0013] With the side grip assembly and the rotating wheel assembly, this device can be placed on the ground, and the user can hold the side grip assembly with both hands to perform rolling exercises, using it as an ab wheel.

[0014] Thus, by combining different modules, different fitness individuals can engage in various fitness training programs.

[0015] In one embodiment, the outer shell is spherical, and an annular groove is provided on the upper part of the opposite surfaces of the left and right shells for placing the outer ring frame.

[0016] The bottom surfaces of the left and right shells are flat, making it easy to place on the ground for use.

[0017] In one embodiment, the outer ring frame is shaped to match the annular groove on the mating surface of the left and right shells, and a horizontal connecting piece is fixed between the two ends of the two arc-shaped sides, with an upwardly arched inner arc frame fixed between the two horizontal connecting pieces.

[0018] The movable connector consists of multiple short rods that are hinged at both ends. One end of the movable connector is hinged to the cross connector, and the other end is hinged to the lower part of the handle.

[0019] In one embodiment, the outer ring of the connecting pipe is provided with a sleeve, one end of the tension rope is wrapped around the outside of the sleeve, and the other end is connected to the inner arc frame. An elastic reset member is provided inside the sleeve for reversing the winding of the tension rope.

[0020] In one embodiment, the side grip assembly includes a first bearing, a support rod, and a side handle. The first bearing is sleeved on the outside of the support rod, and its exterior is fitted onto the inner wall of a connecting tube. The two ends of the support rod are connected to the side handles. The side handle extends beyond the first counterweight assembly to a length sufficient for a person to hold it.

[0021] As another implementation method, in addition to a fixed type, the support rod can also adopt a telescopic structure, with both ends of the support rod able to extend inward, and the inward-facing end of the side handle able to extend into the connecting tube. This can further reduce the space occupied when the instrument is stored.

[0022] In one embodiment, the first counterweight assembly includes a first counterweight block and an outer fixing member connected by an outer ring. The inner side of the first counterweight block is flush with the left end face of the left shell or the right end face of the right shell. A snap-fit ​​member is elastically connected between the first counterweight block and the outer fixing member.

[0023] One end of the snap-fit ​​component is snapped onto the outside of the first counterweight, and the other end can pass through the left end face of the left shell or the right end face of the right shell and snap into the inside of the left shell or the right shell.

[0024] Furthermore, the external fastener includes an inner sleeve and an outer baffle connected to its outer side, with the central space between the inner sleeve and the outer baffle capable of accommodating the passage of a side grip.

[0025] The first counterweight is a conical block with multiple through holes to allow the snap-fit ​​parts to pass through.

[0026] The snap-fit ​​component has a U-shaped longitudinal section, with the open end clamping the first counterweight, and the back is connected to the outer wall of the inner sleeve via a cylindrical spring.

[0027] Preferably, a second counterweight assembly is also connected to the bottom end of both the left and right housings. This further increases the selection options for the counterweight and enhances bottom stability.

[0028] In one embodiment, the rotating wheel assembly includes a rotating wheel that is detachably connected to the bottom surfaces of the left and right housings, and rotating sleeves are provided inside the left and right housings at the position of the rotating wheel.

[0029] In addition, it includes dust covers, which are fitted onto the bottom surfaces of the left and right housings after the rotating wheels are removed.

[0030] Through the above design, the present invention provides a multifunctional fitness instrument that achieves two functions through a detachable first counterweight component. On the one hand, different weights of counterweight can be changed according to the different physical conditions of each person. On the other hand, the fitness instrument has sufficient weight to maintain its stability when using the lifting component to perform lifting movements.

[0031] The lifting component of this invention, in conjunction with the added weight of the instrument, allows for repeated upward pulling movements, thus providing upper limb training. The side grip component, in conjunction with the rotating wheel component, allows the instrument to be placed on the ground, and the user can use the side grip component for rolling training, effectively functioning as an ab wheel. Therefore, through different combinations of the modules, various fitness training methods can be implemented for different individuals. Attached Figure Description

[0033] See Figures 1-4 This embodiment provides a multifunctional fitness instrument with an overall spherical structure, specifically including a shell 1, a lifting assembly 2, a side grip assembly 3, and a rotating wheel assembly 6.

[0034] The outer casing 1 includes a detachably connected left casing 11 and a right casing 12, with coaxial connecting pipes 13 arranged on opposite sides of the left casing 11 and the right casing 12.

[0035] The upper part of the outer casing 1 has an opening, and a lifting assembly 2 is provided between the opening and the connecting tube 13. The lifting assembly 2 includes a tension rope 21 wrapped around the outside of the connecting tube 13 and an outer ring frame 23 on the outside of the upper opening of the outer casing 1. The lower side of the outer ring frame 23 is connected to the tension rope 21 through an inner arc frame 24, and the upper side is connected to a handle 27 through a movable connector 26. When the handle 27 moves upward to the maximum stroke of the movable connector 26, it can drive the outer ring frame 23 and the inner arc frame 24 upward. See Figure 9 As shown.

[0036] In this embodiment, the inner arc frame 24 can be made of aluminum alloy to bear the tension of the tension rope 21, and the outer side of the handle 27 is wrapped with leather material to improve grip comfort and stability.

[0037] The outer casing 1 has a first counterweight component 4 that can be detachably connected to both sides.

[0038] A side grip assembly 3 is connected inside the connecting tube 13, and both ends of the side grip assembly 3 extend out of the first counterweight assembly 4.

[0039] The bottom of the outer casing 1 is detachably connected to a rotating wheel assembly 6.

[0040] The present invention achieves two functions through the detachable first counterweight component 4: on the one hand, different weights can be replaced according to the different physical conditions of each person; on the other hand, the fitness equipment has sufficient weight to maintain its stability when using the lifting component 2 to perform lifting movements.

[0041] The lifting component 2 of this invention, in conjunction with the added weight of the instrument, can perform repeated upward pulling movements for upper limb training. In this mode, the rotating wheel assembly 6 at the bottom of the outer casing 1 needs to be removed.

[0042] The side grip assembly 3, in conjunction with the rotating wheel assembly 6, allows the device to be placed on the ground. By holding the side grip assembly 3 with both hands, the device can be rolled for training and used as an ab wheel.

[0043] Thus, by combining different modules, different fitness individuals can engage in various fitness training programs.

[0044] The following is combined with Figures 5-10 The specific structure of the multifunctional fitness instrument in this embodiment will be introduced.

[0045] First see Figure 6 In this embodiment, the outer shell 1 is spherical in shape, and an annular groove is provided on the upper part of the opposite surfaces of the left shell 11 and the right shell 12 for placing the outer ring frame 23.

[0046] The bottom surfaces of the left housing 11 and the right housing 12 are flat, making it easy to place the wheel assembly 6 on the ground for use after disassembly.

[0047] In this embodiment, the outer ring frame 23 is shaped to match the annular grooves on the mating surfaces of the left and right housings 12. In the front view, it is a U-shape with the opening facing upwards, and in the side view, it is an arc shape with the opening facing downwards. A horizontal connecting member 25 is fixed between the two ends of the two arc-shaped sides of the outer ring frame 23, and an upwardly arched inner arc frame 24 is fixed between the two horizontal connecting members 25. To increase the contact area for gripping the inner arc frame 24, the horizontal connecting members 25 are positioned as close as possible to the lower end of the outer ring frame 23. (See [reference]). Figure 4 .

[0048] The movable connector 26 includes multiple short rods that are hinged at both ends. One end of the movable connector 26 is hinged to the cross connector 25, and the other end is hinged to the lower part of the handle 27.

[0049] In this embodiment, the movable connector 26 includes two short rods, see [link to previous embodiment]. Figure 5 As shown. When this fitness equipment is not in use, the outer ring frame 23 is folded up to abut against the annular groove on the mating surface of the left and right shells 12, and the handle 27 covers the outside of the horizontal connecting member 25, thus maintaining minimal space occupation. In use, pulling the handle 27 upward will first extend the movable connecting member 26 to its longest length, and then move the outer ring frame 23 and the inner arc frame 24 upward together. The function of the movable connecting member 26 here is to use its extension to leave a gripping space between the handle 27 and the inner arc frame 24, making it convenient for the user to train.

[0050] Preferably, two movable connectors 26 are provided on each cross connector 25, symmetrically arranged on both sides of the inner arc frame 24.

[0051] See Figure 6 The connecting tube 13 is located between the left housing 11 and the right housing 12. A sleeve 22 is provided around the outer ring of the connecting tube 13. One end of the tension rope 21 is wrapped around the sleeve 22, and the other end is connected to the inner arc frame 24. An elastic reset member is provided inside the sleeve 22 for reversing the winding of the tension rope 21.

[0052] Specifically, see Figure 7 As shown, the sleeve 22 includes an outer tube 221 and an inner tube 222. A second bearing 223 is provided between the two tubes, and coil springs 224 are connected between the two ends. The inner tube 222 and the connecting tube 13 are interference-fitted. The tension rope 21 is wrapped around the outside of the outer tube 221. When the lifting assembly 2 is lifted, the tension rope 21 is pulled upward, causing the outer tube 221 to rotate relative to the inner tube 222. The coil spring 224 is gradually tightened. When the force is released by hand and the lifting assembly 2 moves downward, the elastic force of the coil spring 224 causes the outer tube 221 to rotate in the opposite direction, wrapping the tension rope 21 around the outer tube 221.

[0053] The following is combined with Figure 6 and Figure 7 Let's introduce the side grip assembly 3. The side grip assembly 3 includes a first bearing 31, a support rod 32, and a side grip 33. There are one or more first bearings 31, which are sleeved on the outside of the support rod 32 and externally fitted onto the inner wall of the connecting tube 13. The two ends of the support rod 32 are connected to the side grips 33. The side grips 33 extend beyond the first counterweight assembly 4 to accommodate a person's hand.

[0054] In one embodiment, the support rod 32 is a hollow tube with a larger outer diameter in the middle section than in the outer diameters of the two sides. Multiple first bearing arrays are fitted onto the middle section of the support rod 32, and sealing sleeves 34 are provided between the two sides of the support rod 32 and the side grips 33. Preferably, the side grips 33 are made of silicone material for easy hand gripping.

[0055] See Figure 8 As another implementation method, in addition to being fixed, the support rod 32 can also be telescopic, with both ends of the support rod 32 able to extend inward, and the inward-facing end of the side handle 33 able to extend into the connecting tube 13. This can further reduce the space occupied when the instrument is stored.

[0056] See below. Figure 7 The specific structure of the first counterweight assembly 4 is illustrated by the diagram showing its separation from the left housing 11. The first counterweight assembly 4 includes a first counterweight block 41 and an outer fixing member 42 connected by an outer ring. The inner side of the first counterweight block 41 is flush with the left end face of the left housing 11 or the right end face of the right housing 12. A snap-fit ​​member 43 is elastically connected between the first counterweight block 41 and the outer fixing member 42.

[0057] One end of the snap-fit ​​component 43 is snapped onto the outside of the first counterweight 41, and the other end can pass through the left end face of the left housing 11 or the right end face of the right housing 12 and snap into the inside of the left housing 11 or the right housing 12.

[0058] Furthermore, the outer fixing member 42 includes an inner sleeve 422 and an outer baffle 421 connected to its outer side, the central axis of which coincides with the axis of the support rod 32.

[0059] The outer baffle 421 is an annular baffle, and its inner diameter is the same as that of the inner sleeve 422. The central space between the inner sleeve 422 and the outer baffle 421 can accommodate the side handle 33 passing through.

[0060] In this embodiment, the first counterweight 41 is a conical block with two through holes perpendicular to its thickness, allowing the snap-fit ​​component 43 to pass through. The outer ring of the outer baffle 421 is bolted to the first counterweight 41.

[0061] The snap-fit ​​component 43 has a rectangular structure in the side view and a U-shaped longitudinal section. The open end clamps the first counterweight 41, and the back is connected to the outer wall of the inner sleeve 422 through a cylindrical spring 44.

[0062] Furthermore, the snap-fit ​​component 43 can be further divided into a long baffle, a short baffle, and a spring baffle connected at the bottom of the two. The outer end face of the long baffle is flush with the inner wall of the outer baffle 421 and extends to the outside of the first counterweight 41 in a direction perpendicular to the axis of the inner sleeve 422, so as to facilitate manual pressing operation.

[0063] The length of the spring baffle is the sum of the thickness of the first counterweight 41 and the thickness of either the left shell 11 or the right shell 12.

[0064] The left and right shells are symmetrical structures. The following describes the position of the short baffle and the usage of the snap-fit ​​part 43, taking the left shell 11 as an example. The left end face of the left shell 11 is a closed surface to fit against the right end of the first counterweight 41. Two rectangular holes are opened on the left end face of the left shell 11. The size of the rectangular holes is the same as the size of the through holes on the first counterweight 41, and both are slightly larger than the size of the short baffle.

[0065] When installing the first counterweight assembly 4, press down the long baffle, causing the locking piece 43 to compress the cylindrical spring 44 inward and move towards the inner sleeve 422 as a whole until the short baffle is below the rectangular hole on the left housing 11. Then push it inward until the short baffle extends into the left housing 11. Release the long baffle; the short baffle, under the elastic force of the cylindrical spring 44, will lock into the inner side of the left housing 11, thus completing the installation of the first counterweight assembly 4. For disassembly, press down the long baffle again and pull it out in the opposite direction to replace the first counterweight block 41. The first counterweight block 41 can be made of different materials and comes in various weight specifications for use in different fitness programs.

[0066] In a preferred embodiment, the inner end face of the first counterweight 41 is non-planar, specifically, it can be a structure in which the middle part protrudes away from the outer baffle 421. Correspondingly, the outer end faces of the left shell 11 and the right shell 12 are concave to enclose the first counterweight 41. This design can further increase the volume of the first counterweight 41 and increase the adjustable range of the counterweight.

[0067] See Figure 5 A second counterweight assembly 5 is bolted to one end of the left shell 11 and the right shell 12 near the bottom. This further increases the selection space for counterweights and enhances bottom stability.

[0068] See Figure 5 In this embodiment, the rotating wheel assembly 6 includes two rotating wheels 61, which are detachably connected to the bottom surfaces of the left housing 11 and the right housing 12 by a snap-fit ​​method. When performing a lifting action, the rotating wheels 61 are removed, and the device is placed on the ground for use. When performing ground rolling training, the rotating wheels 61 are snapped into the reserved holes on the bottom surfaces of the left housing 11 and the right housing 12.

[0069] To prevent dust from entering the interior of the housing from the bottom when the rotating wheel is not in use, a rotating sleeve 62 is provided inside the left housing 11 and the right housing 12 at the position of the rotating wheel 61.

[0070] In addition, a dust cover 63 is provided, see [link / reference] Figure 10 As shown, after the rotating wheel 61 is disassembled, it is assembled on the bottom surface of the left housing 11 and the right housing 12 to seal the hole.
