Description

Technical Field

[0001] This application relates to the field of sports equipment technology, and more particularly to a fitness equipment. Background Technology

[0002] Fitness equipment is a tool or device used for physical exercise, increasing muscle strength, improving flexibility, endurance, and cardiovascular function. Strength training equipment, in particular, stimulates muscle growth and increases strength by working against gravity. Fitness equipment is typically available in various weights, measured in kilograms. During weight training, different weights are used depending on an individual's muscle level, and the weight is adjusted based on the degree of muscle fatigue.

[0003] To facilitate home workouts, an adjustable-weight fitness device has been developed. This device includes a handle and various weight blocks of different sizes. Adjusting the weight involves first removing the nuts on both sides of the handle to detach the original weight blocks, then installing the new weight blocks, and finally tightening the nuts to prevent them from shifting during exercise. The entire weight adjustment process is quite cumbersome. Utility Model Content

[0004] In view of this, this application provides a fitness device that can improve the problem of users having trouble adjusting the weight of the fitness device.

[0005] One embodiment of this application provides a fitness device, which includes a weight base and a weight assembly. The weight base has multiple mounting positions spaced apart, and also has a handle. The weight assembly includes multiple weight blocks, each weight block being detachably connected to a corresponding mounting position.

[0006] In the above embodiment, each weight block is detachably connected to a mounting position on the weight base. During use, the user holds the handle and places the weight base next to the weight assembly, then selects which weight block to install in the mounting position without needing to remove the weight using nuts or other methods. This adjustment method allows the user to quickly adjust the weight of the entire fitness equipment, making the entire process quick and convenient.

[0007] In at least one embodiment, multiple mounting positions are arranged along the direction of gravity, and the counterweight base is provided with multiple first mounting holes corresponding to the mounting positions at intervals along the direction of gravity. Multiple counterweights are stacked layer by layer along the direction of gravity, and each counterweight is provided with a second mounting hole. The fitness equipment also includes a connecting rod, which passes through the first mounting hole located at the same mounting position and the second mounting hole corresponding to the first mounting hole.

[0008] The weights are installed using the first and second mounting holes in a corresponding configuration. During use, the user holds the handle and places the weight base next to the weight assembly, aligning the first and second mounting holes. The connecting rod is then passed through both holes to attach the weights to the weight base. Since multiple weights are stacked in the direction of gravity, when connecting the weights to the weight base, connecting the topmost weight will only connect one weight. Connecting a weight other than the topmost weight will allow that weight to support the weights stacked above it, thus adjusting the weight distribution of the fitness equipment. This adjustment method eliminates the need for users to move or select weights; simply changing the position of the connecting rod quickly and easily adjusts the weight of the entire fitness equipment.

[0009] In at least one embodiment, the counterweight base includes a mounting plate, a plurality of first mounting holes are spaced apart from the mounting plate along the direction of gravity, the counterweight block is provided with a mounting groove, and a second mounting hole penetrates the groove wall of the mounting groove. When the counterweight block is connected to the counterweight base, the mounting plate is partially accommodated in the mounting groove.

[0010] By using the mounting groove and mounting plate, the connecting rod restricts five degrees of freedom of the counterweight when it passes through the first and second mounting holes. The groove wall abuts against the side of the mounting plate, further restricting the counterweight's degree of freedom of movement along the connecting rod. This restricts all six degrees of freedom of the counterweight, making the connection between the counterweight and the counterweight base more stable.

[0011] In at least one embodiment, the counterweight base includes a top plate and side plates. The top plate is arranged parallel to the counterweight. The side plates are connected to the top plate and enclose multiple mounting positions. A handle is connected to either the side plate or the top plate, and a mounting plate is connected to both the top plate and the side plates.

[0012] The structural design of the top and side plates allows for the insertion of counterweight components from top to bottom. When the user needs to increase the weight, the mounting plate of the counterweight base can be inserted into the mounting slots of multiple counterweight blocks. Then, the corresponding number of counterweight blocks can be selected from top to bottom. The connecting rod is then inserted into the first and second mounting holes of the corresponding mounting position, connecting the counterweight block at that position to the mounting plate. Simultaneously, the counterweight block at that position supports the counterweight blocks above it, thereby adjusting the weight of the fitness equipment. When the user begins exercising, they hold the handles and pull the counterweight base upwards, causing the mounting plate to leave the mounting slots, while any excess counterweight blocks remain in place.

[0013] In at least one embodiment, there are two mounting plates, which are spaced apart, and a first mounting hole penetrates through the two mounting plates; the counterweight has two mounting slots, and a second mounting hole penetrates through the walls of the two mounting slots, with the two mounting slots of each counterweight corresponding to the two mounting plates.

[0014] By using two mounting plates and two mounting slots, the connecting rod passes through the two first mounting holes to secure the counterweight and counterweight base, giving the counterweight two points of support. Understandably, to facilitate the installation and removal of the counterweight, the mounting slots and mounting plates are fitted with a clearance fit, allowing the counterweight some room to move when connected to the counterweight base. If there were only one mounting plate, meaning the counterweight had only one point of support, the counterweight would easily wobble with the user's movements during strength training, affecting the training experience. Two mounting plates provide two points of support for the counterweight, making it more stable when the user uses the fitness equipment.

[0015] In at least one embodiment, the mounting plate is provided with a groove that extends along the direction of gravity, and a slider is provided on the groove wall of the mounting groove, the slider being slidably connected to the groove.

[0016] The sliding groove and slider allow the counterweight to slide along the direction of gravity against the mounting plate. Understandably, when the user passes the mounting plate of the counterweight base through the mounting groove, the slider and groove act as guides, ensuring that the second mounting hole on the slider aligns with the first mounting hole in the sliding groove. This improves the situation where, when the user places the counterweight base on the counterweight assembly, the first and second mounting holes are horizontally misaligned, preventing the connecting rod from simultaneously passing through both holes.

[0017] In at least one embodiment, a positioning protrusion is provided on one side of the counterweight, and a positioning groove is provided on the other side of the counterweight facing away from the positioning protrusion. When multiple counterweights are stacked in layers along the direction of gravity, the positioning protrusion of one counterweight abuts against the positioning groove of another adjacent counterweight.

[0018] By using the positioning groove and positioning protrusion, the counterweights are locked in place when multiple counterweights are stacked, preventing them from moving left or right. This improves the problem of the mounting plate being unable to be inserted into the mounting slot due to misalignment of the counterweights, and also reduces the possibility of counterweights falling and injuring users.

[0019] In at least one embodiment, the connecting rod includes an elastic body and a rod body. One end of the elastic body is connected to a counterweight. One end of the rod body is connected to the end of the elastic body away from the rod body.

[0020] By setting an elastic connecting rod, the connecting rod will not leave the counterweight seat, thus improving the situation where the connecting rod is lost or far away from the user, making it impossible for the user to adjust the counterweight.

[0021] In at least one embodiment, the top plate has a first connecting hole, the side plate has a second connecting hole, one end of the handle is detachably connected to the first connecting hole, and the other end of the handle is detachably connected to the second connecting hole. The side plate has a second connecting hole, and there are two sets of counterweights. One end of the handle is detachably connected to the second connecting hole of one counterweight, and the other end of the handle is detachably connected to the second connecting hole of the other counterweight.

[0022] The first and second connecting holes allow the counterweight base to be assembled into different types of fitness equipment based on different types of grips.

[0023] In at least one embodiment, the fitness equipment also includes a base, and two sets of counterweight components are provided, with the two sets of counterweight components placed at intervals on the base, and the two sets of counterweight seats corresponding to the two sets of counterweight components located on the base.

[0024] The base provides a place to store the counterweight components and makes it convenient for users to assemble the counterweight base and components. Attached Figure Description

[0034] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and embodiments, is provided. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0037] Please see Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a fitness device, which includes a weight base 1 and a weight assembly 20. The weight base 1 is provided with a plurality of mounting positions 10 spaced apart. The weight assembly 20 includes a plurality of weight blocks 2, each weight block 2 being detachably connected to a corresponding mounting position 10.

[0038] The weight seat 1 is also equipped with a handle 3. The weight seat 1 and the handle 3 can be used as a kettlebell, dumbbell or barbell. The weight of both the weight seat 1 and the weight block 2 can be set to the common weight of fitness equipment, so that the weight seat 1 can also be used without the weight assembly 20.

[0039] The connection methods between the counterweight base 1 and the counterweight 2 include loading, insertion, and snap-fit. A placement platform can be provided on the counterweight base 1, with the placement surface of the platform divided into different mounting positions 10. Each counterweight 2 can be placed on a mounting position 10 like a weight. Similarly, each counterweight 2 can be stacked, thus dividing the vertical space of the placement platform into different mounting positions 10. Alternatively, slots can be provided on the counterweight base 1, with one slot corresponding to one mounting position 10, allowing the counterweight 2 to be inserted into the slots of the counterweight base 1. Additional fasteners or connectors can also be provided at different positions on the counterweight base 1 as mounting positions 10, enabling the counterweight 2 to be fastened or connected to the mounting positions 10.

[0040] Each weight block 2 is detachably connected to a mounting position 10 via multiple mounting positions 10 on the weight base 1. In use, the user holds the handle 3 and places the weight base 1 next to the weight assembly 20, then selects which weight block 2 to install in the mounting position 10, without needing to remove the weight using nuts or other methods. This adjustment method allows users to quickly adjust the weight of the entire fitness equipment without removing or installing nuts, making the entire process quick and easy.

[0041] Please see Figure 2 and Figure 3 Multiple mounting positions 10 are arranged along the direction of gravity. A counterweight base 1 is provided with multiple first mounting holes 131 corresponding to the mounting positions 10 at intervals along the direction of gravity. Multiple counterweight blocks 2 are stacked layer by layer along the direction of gravity, and each counterweight block 2 is provided with a second mounting hole 211. The fitness equipment also includes a connecting rod 14, which passes through the first mounting holes 131 located in the same mounting position 10 and the corresponding second mounting holes 211.

[0042] The first mounting hole 131 of the mounting plate 13 is located at mounting position 10. The diameter of the first mounting hole 131 is less than or equal to the diameter of the second mounting hole 211, so that even if the counterweight 2 deviates slightly from mounting position 10 due to processing errors, the connecting rod 14 can still pass through the second mounting hole 211 and be inserted into the first mounting hole 131. Similarly, the edges of the first mounting hole 131 and the second mounting hole 211 are chamfered, and the insertion section of the connecting rod 14 is also chamfered, so that the chamfer can guide the connecting rod 14 into the first mounting hole 131 and the second mounting hole 211, while also preventing the edge of the connecting rod 14 from accidentally injuring the user.

[0043] When the counterweights 2 are stacked together, the second mounting holes 211 of the multiple counterweights 2 are also arranged in a row in the direction of gravity, and the interval between the multiple second mounting holes 211 is consistent with the interval between the multiple first mounting holes 131 set along the direction of gravity on the counterweight base 1. This ensures that when the connecting rod 14 changes position, the multiple first mounting holes 131 correspond one-to-one with the multiple second mounting holes 211, so that any counterweight 2 can be connected to the corresponding position on the counterweight base 1 without moving the position of the counterweights 2.

[0044] The first mounting hole 131 passes through the counterweight seat 1, and the second mounting hole 211 passes through the counterweight block 2. The length of the connecting rod 14 is equal to the length of each segment of the first mounting hole 131 plus the length of each segment of the second mounting hole 211, so that the force-bearing area of ​​the connecting rod 14 is larger and the weight of the counterweight block 2 is more evenly distributed.

[0045] The weights are installed in a corresponding configuration via the first and second connecting holes. The weight base 1 has a first mounting hole 131, and each weight block 2 has a second mounting hole 211. Multiple weight blocks 2 are stacked in the direction of gravity to form a weight assembly 20. In use, the user holds the handle 3 and places the weight base 1 next to the weight assembly 20, aligning the first mounting hole 131 and the second mounting hole 211. Then, the connecting rod 14 is passed through the first mounting hole 131 and the second mounting hole 211 to attach the weight blocks 2 to the weight base 1. Because multiple weight blocks 2 are stacked in the direction of gravity, when connecting the weight blocks 2 and the weight base 1, if the topmost weight block 2 is connected, only one weight block 2 will be connected. If a weight block 2 that is not the topmost is connected, it will support the weight blocks 2 stacked above it and be connected to the weight base 1, thus achieving the effect of adjusting the weight specifications of the fitness equipment. This adjustment method eliminates the need for users to move or select counterweight 2 during adjustment. They can simply change the position of connecting rod 14 to quickly adjust the weight of the entire fitness equipment, making the whole process quick and easy.

[0046] Please see Figure 2 and Figure 3 The counterweight base 1 includes a mounting plate 13, and a plurality of first mounting holes 131 are spaced apart along the direction of gravity on the mounting plate 13. The counterweight block 2 is provided with a mounting groove 21, and a second mounting hole 211 penetrates the groove wall of the mounting groove 21. When the counterweight block 2 is connected to the counterweight base 1, the mounting plate 13 is partially accommodated in the mounting groove 21.

[0047] The first mounting hole 131 penetrates the mounting plate 13, forming the first mounting hole 131 on both sides of the mounting plate 13. The counterweight 2 has a flat block structure, and the mounting groove 21 in the middle of the counterweight 2 extends to the edge of the counterweight 2, forming a notch at the edge of the counterweight 2. The second mounting hole 211 also penetrates the counterweight 2 and the mounting groove 21, forming the second mounting hole 211 on both outer sides of the counterweight 2 and both sides of the groove wall of the mounting groove 21. During installation, the mounting plate 13 of the counterweight base 1 can be inserted into the counterweight 2 through the notch, and the positions of the first mounting hole 131 and the second mounting hole 211 correspond.

[0048] By configuring the mounting groove 21 and the mounting plate 13, when the connecting rod 14 passes through the first mounting hole 131 and the second mounting hole 211, the connecting rod 14 restricts five degrees of freedom of the counterweight 2. Meanwhile, the groove wall of the mounting groove 21 abuts against the side of the mounting plate 13, thereby restricting the degree of freedom of the counterweight 2 to move along the direction of the connecting rod 14. This restricts all six degrees of freedom of the counterweight 2, making the connection between the counterweight 2 and the counterweight base 1 more stable.

[0049] Please see Figure 3 and Figure 4 The counterweight base 1 includes a top plate 11 and a side plate 12. The top plate 11 is arranged parallel to the counterweight block 2. The side plate 12 is connected to the top plate 11 and encloses multiple mounting positions 10. The handle 3 is connected to the side plate 12 or the top plate 11. The mounting plate 13 is connected to the top plate 11 and the side plate 12.

[0050] The top plate 11 has the same shape as the counterweight 2. A side plate 12 is connected to one side of the top plate 11, and the side plate 12 and the top plate 11 are perpendicular to each other. Two adjacent sides of the mounting plate 13 are connected to the top plate 11 on one side and to the side plate 12 on the other. The mounting plate 13 is also perpendicular to both the top plate 11 and the side plate 12. The top plate 11 covers the top of the mounting plate 13, while the bottom of the mounting plate 13 is unobstructed. Multiple mounting plates 13 are arranged so that they can be inserted into the mounting slots 21 of the counterweight 2 along the direction of gravity. Understandably, the mounting slots 21 of the multiple counterweights 2 are aligned so that when the multiple counterweights 2 are stacked layer by layer along the direction of gravity, the multiple mounting slots 21 form a mounting slot 21 channel. The depth of this mounting slot 21 channel corresponds to the height of the mounting plate 13. When the inner side of the top plate 11 abuts against the top of the counterweight assembly 20, the bottom surface of the mounting plate 13 is coplanar with the bottom surface of the counterweight assembly 20. Furthermore, the first mounting hole 131 and the second mounting hole 211 correspond one-to-one.

[0051] The structural shape of the top plate 11 and side plate 12 allows the counterweight seat 1 to be inserted into the counterweight assembly 20 from top to bottom. When the user needs to increase the weight, the mounting plate 13 of the counterweight seat 1 can be inserted into the mounting slots 21 of multiple counterweight blocks 2. Then, the corresponding number of counterweight blocks 2 can be selected from top to bottom. The connecting rod 14 is then inserted into the first mounting hole 131 and the second mounting hole 211 of the corresponding mounting position 10, so that the counterweight block 2 at that position is connected to the mounting plate 13. At the same time, the counterweight block 2 at that position supports the counterweight block 2 above it, thereby adjusting the weight of the fitness equipment. When the user starts exercising, he holds the handle 3 and pulls the counterweight seat 1 and the counterweight blocks 2 from bottom to top. The mounting plate 13 leaves the mounting slot 21, while the excess counterweight blocks 2 remain in place.

[0052] Please see Figure 5 and Figure 6 There are two mounting plates 13, which are spaced apart. The first mounting hole 131 penetrates the two mounting plates 13. The counterweight 2 has two mounting grooves 21, and the second mounting hole 211 penetrates the groove wall of the two mounting grooves 21. The two mounting grooves 21 of each counterweight 2 correspond to the two mounting plates 13.

[0053] The two mounting plates 13 and the side plate 12 form a "Π" shape, while the counterweights 2 of the two mounting slots 21 form a "mountain" shape.

[0054] By setting two mounting plates 13 and two mounting slots 21, the connecting rod 14 passes through the two first mounting holes 131 to fix the counterweight 2 and the counterweight base 1, giving the counterweight 2 two support points. Understandably, to facilitate the installation and removal of the counterweight 2, the fit between the mounting slots 21 and the mounting plates 13 is a clearance fit, allowing the counterweight 2 to still have some room to move when connected to the counterweight base 1. If there were only one mounting plate 13, meaning the counterweight 2 had only one support point, the counterweight 2 would easily wobble with the user's movements during strength training, affecting the user's training experience. Two mounting plates 13 provide the counterweight 2 with two support points, making the exercise more stable for the user.

[0055] Please see Figure 5 and Figure 6 The mounting plate 13 is provided with a sliding groove 132, which extends along the direction of gravity. The groove wall of the mounting groove 21 is provided with a slider 212, which is slidably connected to the sliding groove 132.

[0056] The slide groove 132 is located on both inward-facing sides of the two mounting plates 13 along the direction of gravity, and the first mounting hole 131 passes through the groove wall of the slide groove 132. Slider blocks 212 are located on the inner sides of the two mounting slots 21, and second mounting holes 211 pass through the sliders 212. When the sliders 212 slide within the slide groove 132, the second mounting holes 211 on the sliders 212 pass through different mounting positions 10 along the direction of gravity, so that the second mounting holes 211 can correspond to the first mounting holes 131. The sliding groove 132 and the slider 212 allow the counterweight 2 to slide along the direction of gravity against the mounting plate 13. Understandably, when using dumbbells, users typically lift them up and down. When they want to rest or adjust the weight, they place the weight base 1 or the weight base with the counterweight 2 from top to bottom. When the user passes the mounting plate 13 of the weight base 1 through the mounting groove 21 from top to bottom, the slider 212 and the sliding groove 132 act as guides, ensuring that the second mounting hole 211 on the slider 212 aligns with the first mounting hole 131 of the sliding groove 132. This prevents the first mounting hole 131 and the second mounting hole 211 from being misaligned horizontally when the user places the weight base 1 on the weight assembly 20, which would prevent the connecting rod 14 from simultaneously passing through both the first mounting hole 131 and the second mounting hole 211.

[0057] The counterweight 2 has a positioning protrusion 22 on one side and a positioning groove 23 on the other side of the counterweight 2 facing away from the positioning protrusion 22. When multiple counterweights 2 are stacked in layers along the direction of gravity, the positioning protrusion 22 of one counterweight 2 abuts against the positioning groove 23 of another adjacent counterweight 2.

[0058] Three positioning protrusions 22 are provided on the top surface of the counterweight 2, and three positioning grooves 23 are provided on the bottom surface of the counterweight 2. The positions of the positioning protrusions 22 and the positioning grooves 23 correspond. When multiple counterweights 2 are stacked together, the three positioning protrusions 22 of the counterweight 2 at the mounting position 10 are inserted into the three positioning grooves 23 of the counterweight 2 at the upper mounting position 10. Conversely, the three positioning grooves 23 of the counterweight 2 at the mounting position 10 are inserted into the three positioning protrusions 22 of the counterweight 2 at the lower mounting position 10. An anti-slip layer can be provided on the outer side of the counterweight 2.

[0059] By using the positioning groove 23 and the positioning protrusion 22 together, when multiple counterweights 2 are stacked, the counterweights 2 are stuck and will not move left or right, thus avoiding the problem that the mounting plate 13 cannot be inserted into the mounting slot 21 due to misalignment of the counterweights 2, and also preventing the counterweights 2 from falling and injuring the user.

[0060] Please see Figure 7 The connecting rod 14 includes an elastic body 141 and a rod body 142. One end of the elastic body 141 is connected to the counterweight 1. One end of the rod body 142 is connected to the end of the elastic body 141 away from the rod body 142.

[0061] The elastic body 141 is an elastic rope. The top of the counterweight 1 is provided with a hanging ring. One end of the elastic body 141 is connected to the hanging ring on the top of the counterweight 1, and the other end is connected to the rod 142. The rod 142 can be inserted into the first mounting hole 131 and the second mounting hole 211. The rod 142 is provided with a grip end. The grip section is larger than the second mounting hole 211. The grip section is provided with anti-slip texture. The user can grip the grip section to control the movement of the rod 142.

[0062] By setting the elastic body 141 to connect the rod body 142, the connecting rod 14 will not leave the counterweight seat 1, thus avoiding the situation where the connecting rod 14 is lost or far away from the user, making it impossible for the user to adjust the counterweight 2.

[0063] Please see Figure 3 The top plate 11 is provided with a first connecting hole 133, and the side plate 12 is provided with a second connecting hole 134. One end of the handle 3 is detachably connected to the first connecting hole 133, and the other end of the handle 3 is detachably connected to the second connecting hole 134. The side plate 12 is provided with a second connecting hole 134. There are two sets of counterweights 1. One end of the handle 3 is detachably connected to the second connecting hole 134 of one counterweight 1, and the other end of the handle 3 is detachably connected to the second connecting hole 134 of the other counterweight 1.

[0064] When the handle 3 is bent, with one end connected to the first connecting hole 133 and the other end connected to the second mounting hole 211, the handle 3, the counterweight seat 1, and the counterweight assembly 20 form a kettlebell. A short handle 3 with both ends connected to a counterweight seat 1 and a counterweight assembly 20 forms a dumbbell. A long handle 3 with both ends connected to a counterweight seat 1 and a counterweight assembly 20 forms a barbell. The outer layer of the handle 3 has an anti-slip layer, and a long handle 3 can be composed of multiple short handle segments.

[0065] By setting the first connecting hole 133 and the second connecting hole 134, the counterweight seat 1 can be assembled into different types of fitness equipment according to different types of grips 3.

[0066] Please see Figure 1 The fitness equipment also includes a base 4, and two sets of counterweight components 20 are provided. The two sets of counterweight components 20 are placed at intervals on the base 4, and the two sets of counterweight seats 1 correspond to the two sets of counterweight components 20 located on the base 4.

[0067] The base 4 has positioning protrusions 22 to prevent the counterweight 2 from shifting when placed on the base 4. When the handle 3, counterweight seat 1, and counterweight assembly 20 form a dumbbell, two sets of counterweight assembly 20 can be placed on the base 4. The spacing between the two sets of counterweight assembly 20 is just right so that the counterweight seats 1 at both ends of the short handle 3 can be connected to the two sets of counterweight assembly 20 one by one. The floor has threaded holes, and the base 4 has through holes, allowing the base 4 to be installed on the floor using screws.

[0068] The base 4 provides a place to house the counterweight assembly 20 and facilitates the user's assembly of the counterweight base 1 and the counterweight assembly 20.

[0069] Please see Figure 8 The fitness equipment also includes a support 5 and two bases 4, which are detachably connected to the support 5.

[0070] The support frame 5 is composed of square tubing, and two bases 4 are installed on the support frame 5. Each base 4 can hold one set of dumbbells, meaning that one support frame 5 can hold two sets of dumbbells. The support frame 5 also includes a shelf 51 for placing items such as towels, water bottles, and mobile phones.

[0071] The support 5 and two bases 4 allow the user to exercise both their left and right arms simultaneously.
