Description

Technical Field

[0001] This utility model belongs to the technical field of climbing machine structure for fitness, and specifically refers to a climbing machine with adjustable resistance. Background Technology

[0002] A stair climber, also known as a step stool, is used by a user who steps on the pedals and alternates pressure with both feet, causing the pedals to move up and down along a track. A linkage mechanism between the two pedals ensures simultaneous movement. Some existing exercise equipment with similar structures often incorporate elastic cords between the pedals and the lower part of the frame to increase resistance and achieve higher exercise intensity. However, this structure only generates resistance when the pedals are rising from the middle. As the pedals move downwards, the distance between the pedals and the lower part of the frame decreases, and the elastic cords not only fail to stretch and generate resistance but also sag, posing a safety hazard.

[0003] For example, Chinese patent CN202420547618.9 describes a stepper, including a frame with two slide rails arranged at intervals. Each slide rail has a slidably mounted pedal assembly. The device also includes a linkage mechanism for linking the two pedal assemblies, which drives them to move synchronously in opposite directions. Furthermore, it includes a damping mechanism for providing resistance to the pedal assemblies. This damping mechanism includes a linear elastic element straddling the two slide rails, with its two ends connected to a pedal assembly. The linear elastic element expands and contracts with the synchronous counter-movement of the pedal assemblies, creating a changing elastic force that acts on the pedal assemblies, forming resistance to their movement. While this product provides good fitness results, it also has some drawbacks: the resistance is fixed by the factory-installed elastic cord and cannot be adjusted, preventing users from customizing the resistance to their needs. Summary of the Invention

[0004] The purpose of this invention is to provide a climbing machine with adjustable resistance.

[0005] The purpose of this utility model is achieved as follows:

[0006] An adjustable resistance climbing machine includes a frame, a handhold on the frame, left and right slide rails on the frame, and pedals on the slide rails; the frame is equipped with a resistance adjustment device, and a connecting member is movably mounted on the resistance adjustment device. The connecting member is connected to two pedals respectively, and under the action of the connecting member, the two pedals move in opposite directions synchronously.

[0007] The resistance adjustment device includes a turntable and a resistance element. A connecting element is attached to the turntable and can drive the turntable to rotate. The resistance of rotating the turntable is adjusted by adjusting the distance between the resistance element and the turntable or the contact surface between the resistance element and the turntable.

[0008] Furthermore, a crossbar is provided between the two slide rails, and a fixed pulley or a synchronous pulley is hidden inside the crossbar, so that the connecting piece can move by relying on the fixed pulley or the synchronous pulley.

[0009] Furthermore, the turntable is fixed or integrally formed with gears, and the connecting part is a synchronous belt or the part of the connecting part that meshes with the gear is provided with teeth, so that the connecting part can drive the turntable to rotate in an orderly manner.

[0010] Furthermore, the turntable is an iron disc or an iron ring is fixed to the outside of the turntable, and a magnet is fixed on the resistance component. The resistance to the rotation of the turntable is controlled by adjusting the distance between the magnet and the turntable.

[0011] Furthermore, the resistance element includes a friction plate, and the resistance to the rotation of the turntable is controlled by the contact surface or abutment pressure between the friction plate and the turntable.

[0012] Furthermore, one end of the resistance element is hinged to the frame, and the other end is connected to the drive element, allowing the resistance element to rotate around one end as the drive element moves.

[0013] Furthermore, the driving component is a knob or toggle switch, which is connected to a resistance component.

[0014] Furthermore, the resistance element is a flexible element, and the surface of the flexible element is provided with friction pads. The resistance element can be deformed by the turntable so that the friction pads can be attached to the turntable.

[0015] Furthermore, the slide rail is provided with a groove, the pedal is provided with a bracket, and a pulley is rotatably mounted on the bracket; the groove has a built-in cavity, the bracket can extend into the built-in cavity, and the pulley on the bracket is located in the built-in cavity and moves along the inner wall of the built-in cavity; the groove is located on the side wall or lower wall of the slide rail; the slide rail is a one-piece molded metal profile.

[0016] Furthermore, the pedals are located on the side of the slide rails, with two pedals positioned between the two slide rails. The pedals are connected to the slide rails via brackets and are suspended on the side of the slide rails.

[0017] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0018] 1. This utility model incorporates a resistance adjustment device within the support frame, allowing users to adjust the resistance of the two pedals for enhanced workout results. Furthermore, the resistance adjustment device transmits resistance via a flexible connector, ensuring uniform resistance on both pedals, which then move in opposite directions synchronously.

[0019] 2. The resistance adjustment device of this utility model adopts at least the following two methods: Method 1, using magnetic resistance, where a magnet is provided on the resistance element, and the turntable is an iron disc or an iron ring is fixed to the outside of the turntable. The resistance to the rotation of the turntable is controlled by adjusting the distance between the magnet and the turntable. Method 2, using friction, where the resistance element includes a friction plate. The resistance to the rotation of the turntable is controlled by the contact surface or abutment pressure between the friction plate and the turntable. Both methods are acceptable, and both methods are achieved by adjusting the gap between the resistance element and the turntable; the larger the gap, the smaller the resistance.

[0020] 3. The crossbar of this utility model is provided with a fixed pulley or a synchronous pulley. The connecting part can move by relying on the fixed pulley or the synchronous pulley. It is preferred to use a synchronous pulley. The surface of the connecting part is provided with teeth that mesh with the synchronous pulley.

This structure makes the movement position connection more stable. The foot pedal is located between two slide rails and suspended on the inner side of the two slide rails. The purpose of this structure is to provide the user with a suspended movement experience, while ensuring sufficient strength, thus giving the user a more novel user experience.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-7 As shown:

[0031] An adjustable-resistance climbing machine includes a frame 1 with a handhold 19. The specific shape of the frame 1 is determined by the manufacturer, as long as it allows the user to slide using the pedals after unfolding. The frame 1 has left and right slide rails 11, with pedals 2 mounted on the slide rails 11. A resistance adjustment device is installed inside the frame 1, with a connecting member 32 movably mounted on the device. The connecting member 32 is a non-extensible flexible component, connecting two pedals 2 respectively. Under the action of the connecting member 32, the two pedals 2 move synchronously in opposite directions. The resistance adjustment device includes a turntable 33 and a resistance element 34. The connecting member 32 is connected to the turntable 33 and can drive the turntable 33 to rotate. The resistance of rotating the turntable is adjusted by adjusting the distance between the resistance element and the turntable, or the contact surface between the resistance element and the turntable. The connecting member can be a single piece, with one end fixed to one pedal and the other end fixed to the other pedal, and the middle part movably mounted on the turntable. The connector can also be two strands, one end of which is fixed to one of its pedals and the other end is fixed to the turntable; the other strand is fixed to one of its pedals and the other end is fixed to the turntable; during the rotation of the turntable, one strand is wound around the turntable to achieve contraction, and the other strand is released from the turntable to achieve extension.

[0032] A crossbar 12 is provided between the two slide rails 11. A fixed pulley or a timing pulley 13 is hidden inside the crossbar 12, and the connecting member 32 can move by relying on the fixed pulley or timing pulley 13. If the surface of the connecting member is smooth, then a fixed pulley is provided inside the crossbar; if the surface of the connecting member has teeth, then a timing pulley is provided inside the crossbar, and the connecting member meshes with the timing pulley. The specific scheme is determined by the manufacturer. The attached figure shows the scheme of timing pulley and timing belt.

[0033] The turntable 33 is fixed or integrally formed with a gear 331. The connecting member is a synchronous belt or the part of the connecting member that meshes with the gear is provided with teeth. The connecting member 32 can drive the turntable 33 to rotate in an orderly manner.

[0034] At least the following methods can be used to provide resistance to the turntable: Method 1: The turntable is an iron disc or has an iron ring fixed to its outer side. A magnet is fixed to the resistance component. The resistance to the turntable's rotation is controlled by adjusting the distance between the magnet and the turntable; the closer the magnet is to the turntable, the greater the rotational resistance. Method 2: The resistance component includes a friction plate 35. The resistance to the turntable's rotation is controlled by adjusting the contact surface or abutment pressure between the friction plate 35 and the turntable 33; the greater the force of the friction plate against the turntable or the larger the contact surface, the greater the rotational resistance. Preferably, the resistance component is a flexible component with a friction plate on its surface. The resistance component can deform with the turntable to allow the friction plate to adhere to the turntable.

[0035] At least the following methods can be used to move the resistance component: Method 1: One end of the resistance component is hinged to the frame, and the other end is connected to the drive component. Moving the drive component causes the resistance component to rotate around one end. The drive component has a knob 31; rotating the knob 31 allows the resistance component to move closer to the turntable. A torsion spring can be installed at the hinge position of the resistance component to move the resistance component away from the turntable, or the resistance component can have a certain elasticity, allowing its own elasticity to move it away from the turntable. The attached diagram shows a soft rope between the knob and the resistance component. Rotating the knob causes the soft rope to wrap around the knob shaft, thereby pulling the resistance component. The knob can have protrusions and grooves on the end face that contacts the frame. Rotating the knob allows the protrusions to remain in different grooves, thus keeping the knob at the desired angle. Of course, other methods can also be used to keep the knob in a designated position. Method 2: One end of the resistance component is hinged to the frame, and the other end is connected to the drive component. Moving the drive component causes the resistance component to rotate around one end. The driving component is a toggle switch. Pushing the toggle switch causes the driving component to swing around its axis. The frame has slots with several notches on the sides for the toggle switch to stop. By stopping the toggle switch at different notches, the distance between the resistance component and the turntable can be controlled. Either a toggle switch or a knob can be used, as long as it controls the swing of the resistance component. Limiting structures can also be added to the toggle switch or knob to keep them in the desired position. Various limiting structures are available for manufacturers to choose from, such as a protruding limiter corresponding to a groove.

[0036] The slide rail 11 is provided with a groove 111, and the pedal 2 is provided with a bracket 21, on which a pulley 212 is rotatably mounted. The groove 111 has a built-in cavity, into which the pulley frame 211 of the bracket can extend. The pulley 212 on the pulley frame 211 is located within the built-in cavity and moves along the inner wall of the cavity. The groove 111 is located on the side wall or bottom wall of the slide rail 11. Preferably, the groove 111 is located at the bottom of the slide rail 11, so the connection position is not visible to the user during use, and the surface of the slide rail is smooth and aesthetically pleasing. The built-in sliding connection structure makes the connection position less susceptible to contact with external objects and damage. This sliding part of the structure is more stable, and the user's clothing and miscellaneous items are less likely to get tangled on the pulley position. The slide rail 11 is a one-piece molded metal profile. Preferably, both ends of the metal profile slide rail need to be sealed with a crossbar or plug below.

[0037] The pedals 2 are located on the side of the slide rail 11, with two pedals 2 respectively between the two slide rails 11. The pedals are connected to the slide rail grooves only through brackets, and the pedals are suspended on the side of the slide rails. The pedals 2 suspended on the side can reduce the transport height of the climbing machine, thereby reducing transportation costs; moreover, they give users a feeling of suspended movement, providing them with a more novel user experience.

[0038] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
