Description

Technical Field

[0001] This utility model belongs to the field of training equipment technology, and in particular relates to a non-powered treadmill. Background Technology

[0002] A non-motorized treadmill is a treadmill that relies on the user's feet to drive the treadmill belt. It does not have a motor inside, aiming to enhance workout intensity. As training intensity increases, users often incorporate weight training on non-motorized treadmills, such as running or walking with dumbbells, to improve the strength of joints and muscles in various parts of the body and to exercise the smaller muscle groups surrounding the target muscle groups. However, this method not only makes it difficult to achieve effective weight training but also poses certain safety hazards. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a non-powered treadmill that enables effective and stable weight training while ensuring safe training.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A non-powered treadmill includes: a treadmill body, including a belt assembly and a support assembly, the support assembly being disposed on the belt assembly; and a load-bearing mechanism, including a support arm, a counterweight, and a grip, one end of the support arm being rotatably connected to the support assembly, the counterweight and the grip being spaced apart on the support arm, and the grip being for a user to hold.

[0006] Furthermore, the load-bearing mechanism also includes a limiting seat, which is disposed on the bracket assembly and located below the support arm, and is used to limit the movement of the support arm.

[0007] Furthermore, the support arm includes a first support section and a second support section connected to the first support section. The first support section is rotatably connected to the bracket assembly. The counterweight and the gripping member are spaced apart on the second support section. The second support section is bent relative to the first support section toward the outside of the track assembly. The second support section is limited and engaged with the limiting seat.

[0008] Furthermore, the limiting seat includes a limiting beam and a connecting member. The connecting member and the limiting beam are connected at an angle. Both the connecting member and the limiting beam are disposed on the bracket assembly and are spaced apart along the height direction of the bracket assembly. The limiting beam is located above the connecting member and cooperates with the supporting arm for limiting.

[0009] Furthermore, the load-bearing mechanism also includes a rotating shaft, one end of the support arm is provided with a shaft hole, the rotating shaft is disposed on the bracket assembly and inserted into the shaft hole.

[0010] Furthermore, the load-bearing mechanism also includes a mounting shaft, which is disposed on the support arm, and the counterweight is detachably fitted onto the mounting shaft.

[0011] Furthermore, the gripping component includes a hand-held part, a connecting rod, and a fixing part. The hand-held part is located at one end of the connecting rod, and the fixing part is located at the other end of the connecting rod. The fixing part is detachably connected to the support arm.

[0012] Furthermore, the connecting rod includes a first rod segment, a second rod segment, and a third rod segment connected in sequence. The first rod segment is connected to the fixing part, and the third rod segment is connected to the hand-held part. The first rod segment extends along the width direction of the track assembly and toward the inside of the track assembly. The second rod segment extends upward along the height direction of the track assembly. The third rod segment extends along the width direction of the track assembly and away from the support assembly.

[0013] Furthermore, the number of load-bearing mechanisms is two, and the support assembly includes two support rods. The two support rods are respectively disposed on both sides of the track assembly along its own width direction, and the two load-bearing mechanisms are respectively disposed on the two support rods.

[0014] Furthermore, the non-powered treadmill also includes a storage tube, which is disposed on the support assembly.

[0015] This utility model has the following beneficial effects:

[0016] (1) A support arm is rotatably connected to the support assembly, and counterweights and grips are spaced apart on the support arm. Therefore, during training, the user can stand on the track assembly, hold the grips, and rotate the support arm as a pivot point to raise the counterweights, thus placing the user under load and achieving the purpose of weight training. Since the counterweights are always connected to the support assembly through the support arm, they will not slip during training. At the same time, the user can also pull on the support arm for effective support, preventing falls from the track assembly due to insufficient strength, thereby ensuring the user's safety during training. In addition, the support arm is rotatable, so the grips can be positioned at different heights by rotation, making it convenient for users of different heights to use, thereby achieving effective and stable weight training.

[0017] (2) A limiting seat is installed below the support arm to limit the swing amplitude of the support arm and prevent it from swinging too much and hitting the user's legs, thereby improving safety during training. At the same time, when not in use, the support arm can be supported on the limiting seat, making it convenient for the user to hold the grip.

[0018] (3) The support arm is designed as a first support section and a second support section with a bend. The second support section bends relative to the first support section along the outer side towards the track assembly. This not only makes it easier for the second support section to abut against the limit seat, but also makes the second support section face outward, reducing the space occupied by the second support section on the inner side, avoiding the second support section from easily hitting the user during training, and improving the user experience of the non-powered treadmill.

[0019] (4) The mounting shaft facilitates the installation of counterweights on the support arm. Since the installation between the counterweights and the mounting shaft is detachable, the specifications and quantity of the counterweights can be changed according to the user's load requirements to meet the needs of different load training and improve the applicability of the non-powered treadmill.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, in this utility model, descriptions involving "first," "second," etc., are 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 utility model.

[0030] In one embodiment, please combine Figures 1 to 3This application provides a non-powered treadmill 100, which includes: a treadmill body, including a belt assembly 10 and a support assembly 20, the support assembly 20 being disposed on the belt assembly 10; and a load-bearing mechanism 30, including a support arm 32, a counterweight 31, and a grip 33, one end of the support arm 32 being rotatably connected to the support assembly 20, the counterweight 31 and the grip 33 being spaced apart on the support arm 32, and the grip 33 being used for the user to hold.

[0031] The aforementioned non-powered treadmill 100 has a support arm 32 rotatably connected to the support assembly 20. A counterweight 31 and a grip 33 are spaced apart on the support arm 32. Therefore, during training, the user can stand on the belt assembly 10 and hold the grip 33, using one end of the support arm 32 as a pivot point to rotate and raise the counterweight 31, thus placing the user under load and achieving the purpose of weight training. Since the counterweight 31 is always connected to the support assembly 20 through the support arm 32, it will not slip during training. Simultaneously, the user can pull on the support arm 32 for effective support, preventing falls from the belt assembly 10 due to insufficient strength, thereby ensuring user safety during training. Furthermore, the support arm 32 is rotatable, allowing the grip 33 to be positioned at different heights, facilitating use by users of different heights and achieving effective and stable weight training.

[0032] It should be explained that users can rotate the track assembly 10 by walking or running, and the track assembly 10 may include structures such as rollers and tracks. When training on the track assembly 10, users can hold the grip 33 and rotate it to lift the counterweight 31 to achieve the purpose of weight training. The number or specifications of the counterweight 31 can be adjusted according to user needs. Furthermore, the relative positions of the counterweight 31 and the grip 33 on the support arm 32 can be in two ways: for example, the counterweight 31 can be positioned between the grip 33 and the support assembly 20; or, the grip 33 can be positioned between the counterweight 31 and the support assembly 20.

[0033] For details, please refer to Figure 1 One end of the support arm 32 is rotatably connected to the bracket assembly 20, the counterweight 31 is located at the other end of the support arm 32, and the grip 33 is located at approximately the middle position of the support arm 32.

[0034] Furthermore, the weight-bearing mechanism 30 also includes a limiting seat 34, which is disposed on the support assembly 20 and located below the support arm 32. The limiting seat 34 is used to limit the movement of the support arm 32. It is understood that the limiting seat 34 located below the support arm 32 restricts the swing amplitude of the support arm 32, preventing excessive amplitude from easily impacting the user's legs and further improving safety during training. Simultaneously, when not in use, the support arm 32 can rest on the limiting seat 34, making it convenient for the user to grip the handle 33.

[0035] Optionally, the limiting seat 34 can be connected to the bracket assembly 20 in various ways, such as bolt connection, snap-fit, riveting, welding, pin connection, etc.

[0036] Furthermore, please refer to Figure 3 The support arm 32 includes a first support section 321 and a second support section 322 connected to the first support section 321. The first support section 321 is rotatably connected to the support assembly 20. The counterweight 31 and the grip 33 are spaced apart on the second support section 322. The second support section 322 is bent outward relative to the first support section 321 toward the outside of the track assembly 10. The second support section 322 is limited and engaged with the limiting seat 34. It can be seen that by designing the support arm 32 with the first support section 321 and the second support section 322 bent outward relative to the first support section 321 toward the outside of the track assembly 10, the second support section 322 not only makes it easier for the second support section 322 to rest against the limiting seat 34, but also makes the second support section 322 face outward, reducing the space occupied by the second support section 322 on the inner side, avoiding the second support section 322 from easily hitting the user during training, and improving the user experience of the non-powered treadmill 100.

[0037] It should be explained that the first support section 321 and the second support section 322 can be connected by bolts, snap-fit, riveting, welding, etc., or they can be designed as an integral structure. When there are two load-bearing mechanisms 30, the distance between the two first support sections 321 in the two load-bearing mechanisms 30 should be smaller than the distance between the two second support sections 322.

[0038] In one embodiment, please refer to Figure 1 The limiting seat 34 includes a limiting beam 341 and a connector 342. The connector 342 is connected to the limiting beam 341 at an angle. Both the connector 342 and the limiting beam 341 are located on the support assembly 20 and are spaced apart along the height direction H of the support assembly 20. The limiting beam 341 is located above the connector 342 and engages with the support arm 32 for limiting. It can be seen that by designing the limiting beam 341 and the connector 342 at an angle, the connector 342 can provide reinforcement, ensuring that the limiting beam 341 stably abuts against the support arm 32.

[0039] Optionally, the limiting beam 341 and the connecting piece 342 can be an integral structure, or they can be combined by bolt connection, welding, snap-fit, etc.

[0040] Further, please refer to Figure 3 The weight-bearing mechanism 30 also includes a rotating shaft 35. One end of the support arm 32 is provided with a shaft hole 323. The rotating shaft 35 is mounted on the bracket assembly 20 and inserted into the shaft hole 323. This facilitates the rotation of the support arm 32 on the bracket assembly 20, making weight-bearing training more convenient.

[0041] In one embodiment, please refer to Figure 3 The weight-bearing mechanism 30 also includes a mounting shaft 36, which is mounted on the support arm 32. The counterweight 31 is detachably fitted onto the mounting shaft 36. Thus, the mounting shaft 36 facilitates the installation of the counterweight 31 onto the support arm 32. Since the installation between the counterweight 31 and the mounting shaft 36 is detachable, the specifications and quantity of the counterweight 31 can be changed according to the user's weight requirements to meet the needs of different weight training exercises, thereby improving the applicability of the non-powered treadmill 100.

[0042] It should be explained that when the counterweight 31 is fitted onto the mounting shaft 36, a pin can be inserted into one end of the mounting shaft 36 to prevent the counterweight 31 from slipping off the mounting shaft 36. Of course, components such as nuts can also be screwed on.

[0043] In one embodiment, please refer to Figure 3 The grip 33 includes a handhold 331, a connecting rod 332, and a fixing part 333. The handhold 331 is located at one end of the connecting rod 332, and the fixing part 333 is located at the other end of the connecting rod 332. The fixing part 333 is detachably connected to the support arm 32. Thus, the fixing part 333 stably fixes the grip 33 to the support arm 32; simultaneously, the handhold 331 allows the user to easily hold the grip 33 for weight training.

[0044] Optionally, the connection between the fixing part 333 and the support arm 32 can be a bolt connection, a snap-fit ​​connection, a pin connection, etc.

[0045] Further, please refer to Figure 3The connecting rod 332 includes a first rod segment 33a, a second rod segment 33b, and a third rod segment 33c connected in sequence. The first rod segment 33a is connected to the fixing part 333, and the third rod segment 33c is connected to the handheld part 331. The first rod segment 33a extends along the width direction W of the track assembly 10 and toward the inside of the track assembly 10. The second rod segment 33b extends upward along the height direction H of the track assembly 10. The third rod segment 33c extends along the width direction W of the track assembly 10 and away from the support assembly 20. It can be seen that the connecting rod 332 is designed with a three-section bending structure in different directions, allowing the handheld part 331 to be in a more suitable position, thus making it easier for the user to grip.

[0046] Specifically, the first segment 33a, the second segment 33b, and the third segment 33c are integral structures, for example, they are manufactured by integral molding through a bending process.

[0047] In one embodiment, please refer to Figure 3 The load-bearing mechanism 30 consists of two components. The support assembly 20 includes two support rods 21, which are respectively located on both sides of the track assembly 10 along its width direction W. The two load-bearing mechanisms 30 are respectively located on the two support rods 21. This allows the user to bear weight with both hands, increasing training intensity.

[0048] It is easy to understand that, for ease of use, the two load-bearing mechanisms 30 should be at the same height on the support rod 21. Additionally, for user convenience, the support assembly 20 may also include two handrails 22, each correspondingly positioned on the support rod 21.

[0049] In one embodiment, please refer to Figure 3 The non-motorized treadmill 100 also includes a storage tube 40, which is mounted on the support assembly 20. This allows users to conveniently place their belongings into the storage tube 40, improving ease of use.

[0050] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
