Description

Technical Field

[0001] This utility model relates to the technical field of fitness equipment, and in particular to a stepper. Background Technology

[0002] As people's living standards improve, the demand for home fitness equipment is increasing. Traditional home walking machines and treadmills can no longer meet people's diverse fitness needs.

[0003] As a result, a stepper machine appeared on the market. Stepper machines have the advantage of not hurting the knees and can specifically target the muscles on the inner thighs, preventing fat accumulation on the inner thighs. They are popular among fitness enthusiasts and those looking to lose weight, and have a broad market prospect. However, the sliding pedals of existing stepper machines usually require the use of elastic ropes to achieve reciprocating movement and resistance adjustment. Elastic ropes are prone to aging, which can cause the sliding pedals to jam when sliding, resulting in uneven use, short lifespan, and poor reliability of the stepper machine. Furthermore, elastic ropes also have the drawback of difficulty in adjusting resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a stepper that has the advantages of improving product lifespan, ensuring smooth gliding, and enhancing fitness training effects.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A stepper includes a frame, two slide seats, and two resistance mechanisms;

[0007] Two sliding plates are slidably mounted on the frame and can reciprocate. Two resistance mechanisms are mounted on the frame to provide resistance to the sliding of the sliding plates.

[0008] The resistance mechanism includes a telescopic cylinder, a movable pulley, and a rigid pull rope. The telescopic piston rod of the telescopic cylinder is connected to the movable pulley, and the movable pulley slides on the frame in the same direction as the slide plate seat. One end of the rigid pull rope is fixed to the frame, and the other end passes around the movable pulley and is connected to the slide plate seat.

[0009] Furthermore, the telescopic cylinder is a pneumatic cylinder or a hydraulic cylinder; the rigid pull rope is a steel wire rope.

[0010] Furthermore, the frame includes a frame body, and the top surface of the frame body is provided with two side-by-side sliding grooves, in which the sliding plate seats are slidably connected respectively; two resistance mechanisms are disposed between the two sliding grooves.

[0011] Furthermore, the left and right sides of the slide are respectively provided with guide rails spaced apart vertically; the left and right ends of the slide block are respectively provided with two pulleys spaced apart front and back, and the pulleys slide between the upper and lower guide rails.

[0012] Furthermore, the guide rail is a round tube, square tube, or elliptical tube; the pulley is recessed with an annular groove that matches the guide rail.

[0013] Furthermore, a fixed seat is provided between the two sliding grooves of the frame body, and the top surface of the fixed seat has two mounting grooves for accommodating telescopic cylinders.

[0014] The end of the telescopic piston rod is provided with a slider, the movable pulley is rotatably installed in the middle opening of the slider, and the left and right side walls of the mounting groove are provided with sliding grooves, and the left and right ends of the slider are slidably connected in the sliding grooves.

[0015] One end of the rigid pull rope is fixed to the center of the bottom surface of the mounting groove, and the other end of the rigid pull rope is connected to the connecting piece on the slide block facing the middle of the frame body.

[0016] Furthermore, the frame also includes a support bracket; the support bracket is foldable and unfoldable and is located below the frame body; the support bracket can be hinged to the rear end of the frame body at a preset angle so that the rear end of the frame body can be tilted upwards; the slide seat is provided with a pedal, which is higher in the front and lower in the back and is inclined to the top surface of the frame body.

[0017] Furthermore, the frame also includes an armrest support; the armrest support is foldable and unfoldable and is located above the frame body; the armrest support can be hinged to the rear end of the frame body at a preset angle for users to hold onto.

[0018] Furthermore, a resistance regulating valve assembly is also installed on the frame; the resistance regulating valve assembly has a connected regulating valve and a regulating knob; the regulating valve is connected to two telescopic cylinders, and the regulating knob is used to adjust the resistance of the telescopic cylinders.

[0019] Furthermore, the telescopic cylinder is either a pneumatic cylinder or a hydraulic cylinder; and the air chambers or oil chambers of the two telescopic cylinders are connected.

[0020] With the above technical solution, when users exercise on this stepper, the two sliding plates are slid back and forth, and the two telescopic cylinders provide resistance to achieve resistance training. The resistance is stable and reliable, resulting in good training effects. Since one end of the rigid rope is fixed, the reciprocating movement of the sliding plate simultaneously drives the other end of the rigid rope to move back and forth, which in turn drives the movable pulley to slide back and forth, thereby compressing or stretching the telescopic piston rod of the telescopic cylinder to obtain the corresponding resistance. Moreover, through the cooperation of the telescopic cylinder, the movable pulley, and the rigid rope, the reciprocating movement of the sliding plate can be achieved smoothly, reliably, and without jamming. Furthermore, the telescopic cylinder is more reliable and has a longer product lifespan, unlike elastic ropes which are prone to aging. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] like Figures 1 to 3 As shown, a stepper 10 of this embodiment includes a frame 1, two slide seats 2 and two resistance mechanisms 3.

[0031] Two sliding bases 2 are slidably connected to the frame 1, and two resistance mechanisms 3 are installed on the frame 1 to provide resistance for the sliding of the sliding bases 2.

[0032] See Figure 4 and Figure 5The resistance mechanism 3 includes a telescopic cylinder 31, a movable pulley 32, and a rigid pull rope 33. The telescopic piston rod 311 of the telescopic cylinder 31 is connected to the movable pulley 32, and the movable pulley 32 slides on the frame 1 in the same direction as the slide plate seat 2. One end of the rigid pull rope 33 is fixed to the frame 1, and the other end passes around the movable pulley 32 and is connected to the slide plate seat 2.

[0033] Therefore, when using the stepper 10, the user can utilize the two telescopic cylinders 31 to provide resistance while sliding back and forth on the two slide seats 2, thus achieving resistance training. Specifically, since one end of the rigid pull rope 33 is fixed, when the slide seat 2 slides back and forth, it can simultaneously drive the other end of the rigid pull rope 33 to move back and forth, which in turn drives the movable pulley 32 to slide back and forth, thereby compressing or stretching the telescopic piston rod 311 of the telescopic cylinder 31 to obtain the corresponding resistance. Moreover, through the cooperation of the telescopic cylinder 31, the movable pulley 32, and the rigid pull rope 33, the reciprocating sliding of the slide seat 2 can be achieved smoothly, reliably, and without jamming. Furthermore, the telescopic cylinder 31 is more reliable in use and is not prone to aging like elastic ropes.

[0034] In this embodiment, the telescopic cylinder 31 can be a common air cylinder or oil cylinder, and the air chamber or oil chamber of the two telescopic cylinders 31 can be connected. Thus, when one telescopic cylinder 31 of the two resistance mechanisms 3 is compressed, the other telescopic cylinder 31 can be lifted up, thereby meeting the user's need for the left and right feet to perform cross-stepping movements.

[0035] In this embodiment, the rigid tension rope 33 can be a steel wire rope or other ropes.

[0036] like Figures 1 to 4 As shown, the frame 1 in this embodiment includes a frame body 11, a support bracket 12, and a handrail bracket 13.

[0037] like Figure 3 As shown, the main frame 11 may include a rear support 111 and a front support 112 arranged at intervals.

[0038] In this embodiment, a resistance regulating valve assembly 4 can also be installed on the rear support 111 of the frame 1. The resistance regulating valve assembly 4 has a connected regulating valve 41 and a regulating knob 42. The regulating valve 41 is connected to two telescopic cylinders 31, and the resistance of the telescopic cylinders 31 can be adjusted by using the regulating knob 42. In this way, the corresponding sliding resistance can be easily adjusted according to the user's needs.

[0039] like Figure 4The top surface of the frame body 11 is provided with two parallel sliding grooves 113, in which the slide plate seat 2 is slidably connected; the left and right sides of the sliding groove 113 are respectively provided with guide rails 114 spaced vertically; the left and right ends of the slide plate seat 2 are respectively provided with two pulleys 21 spaced vertically, which slide between the upper and lower guide rails 114 to provide smooth sliding engagement.

[0040] The skateboard seat 2 in this embodiment is provided with four pulleys 21. Of course, it can also be provided with two or six, etc.

[0041] In this embodiment, the guide rail 114 is a round tube; the pulley 21 is recessed with an annular groove 211 that matches the guide rail 114. This allows the pulley 21 to fit into the guide rail 114, preventing the reciprocating sliding of the slide block 2 from deviating.

[0042] Of course, the guide rail 114 can also be a square tube, an oval tube, or an aluminum profile structure, etc.

[0043] Two slides 113 are formed between the front support 112 and the rear support 111. The front and rear ends of each guide rail 114 are respectively connected to the rear support 111 and the front support 112. A lower cover 115 can also be provided between the left and right guide rails 114 of each slide 113. The front and rear ends of the lower cover 115 can be connected to the front support 112 and the rear support 111 respectively. The lower cover 115 is used to cover the bottom surface of the slide seat 2, and has the functions of safety protection and aesthetics.

[0044] See also Figures 5 to 7 In this embodiment, the two resistance mechanisms 3 are disposed between the two slides 113.

[0045] Specifically, a fixing seat 116 may be provided between the two sliding grooves 113 of the frame body 11. The front and rear ends of the fixing seat 116 can be connected to the front support 112 and the rear support 111, respectively. The top surface of the fixing seat 116 has two mounting grooves 117 for mounting and accommodating the telescopic cylinder 31.

[0046] The end of the telescopic piston rod 311 may be provided with a slider 34, and the movable pulley 32 is rotatably installed in the middle opening of the slider 34. The left and right side walls of the mounting groove 117 are provided with sliding grooves 118, and the left and right ends of the slider 34 are slidably connected in the sliding grooves 118. This allows the movable pulley 32 to cooperate with the slider 34 to slide back and forth in the sliding grooves 118 under the pull of the rigid pull rope 33, and to compress or stretch the telescopic piston rod 311 back and forth.

[0047] In this embodiment, one end of the rigid pull rope 33 can be connected and fixed to the center of the bottom surface of the mounting groove 117 of the fixing seat 116 of the frame body 11, and the other end of the rigid pull rope 33 can be connected to the "L"-shaped connecting piece 22 on the slide plate 2 facing the middle of the frame body 11. Since the slide groove 113 has upper and lower spaced guide rails 114 on both sides, the connecting piece 22 can move back and forth through the upper and lower guide rails 114.

[0048] The support bracket 12 is foldable and expandable and is located below the main frame 11. The support bracket 12 can be hinged to the rear end of the main frame 11 at a preset angle, allowing the rear end of the main frame 11 to be tilted upwards. This allows the main frame 11 to be tilted to improve the exercise effect. Correspondingly, the slide seat 2 can be equipped with a pedal 23, which is tilted at the front and lower at the back, so that the pedal 23 remains approximately horizontal when the main frame 11 is tilted, making it convenient for the user to use.

[0049] The handrail support 13 is foldable and expandable and is located above the main frame 11; the handrail support 13 can be hinged to the rear end of the main frame 11 at a preset angle for the user to hold onto, thereby improving safety during exercise.

[0050] In this embodiment, the hinges between the support bracket 12 and the handrail bracket 13 and the frame body 11 are all adjustable in angle. The specific hinge structure can be referred to the prior art. This part is not the focus of this case, so it will not be described in detail.
