Description

Technical Field

[0001] The utility model relates to a stepper. Background Art

[0002] Chinese patent document CN218572747U discloses an electric elliptical machine, which includes a base, a support frame detachably arranged on the base, a crankshaft rotatably arranged on the support frame, a driving structure for driving the crankshaft to rotate, and a pair of main machine shells covering the driving structure and the support frame. A through hole for the crankshaft is provided at the corresponding position of the pair of main machine shells with respect to the crankshaft. Cranks are provided on both sides of the crankshaft, and rotatable pedals are connected to the outer ends of the cranks. A roller that can roll is provided at the bottom of the pedal and is arranged at one end close to the pedal. The roller and the crank constitute the support for the pedal; a pair of main machine shells are provided with inwardly concave hand-holding grooves at the end where the crankshaft is located. In the utility model, the support frame is detachably arranged on the base, and a pair of main machine shells cover the support frame and the driving structure, which is convenient for disassembling and overhauling the elliptical machine. A pair of main machine shells are provided with inwardly concave hand-holding grooves at the end where the crankshaft is located, which is convenient for moving the elliptical machine from the hand-holding grooves without increasing the external structure of the elliptical machine.

[0003] It can be seen from the specification drawings of the above solution that a controller is provided on the shell, but the controller is flush with the outer surface of the shell, which is not conducive to observing the data of the controller. And usually a remote control for controlling the controller is provided, and the fact that the controller is flush with the outer surface of the shell is not conducive to the alignment control of the remote control. Content of the Utility Model

[0004] The purpose of the utility model is to provide a stepper that is flexible to use and convenient to store.

[0005] The purpose of the utility model is achieved through the following technical means:

[0006] A stepper includes a main machine shell and a controller, and is characterized in that: the controller is arranged on the main machine shell so as to be able to move up and down between a rising position and a falling position. When the controller is in the rising position, the controller protrudes outside the main machine shell. When the controller is in the falling position, the controller sinks into the main machine shell. In this way, when the controller is in the rising position, it is convenient for the user to observe and operate the controller. After use, the controller can also be set back to the falling position, making the operation more flexible and convenient for storage.

[0007] When the controller is in the rising position, the controller can be used as a handle to facilitate the movement of the stepper.

[0008] The controller includes a lifting rod and a control box. The lifting rod is arranged in the main machine shell so as to be able to move up and down, and the control box is arranged at the upper end of the lifting rod. The lifting rod can drive the control box to move up and down.

[0009] When the controller is in the lowered position, the top surface of the control box smoothly transitions with the outer surface of the main body housing. In this way, when the user exercises on the stepper, by setting the controller in the lowered position, the control box will not protrude and affect the user's exercise.

[0010] The top surface of the control box is provided with a control panel for the user to operate and control the working state of the stepper and observe data.

[0011] The control box is rotatably arranged at the upper end of the lifting rod through a pivot shaft. In this way, when the controller is in the raised position, the control box can be rotated to adjust the angle, so as to adapt to different viewing angles of the user, and after adjusting the angle, the remote control can be better aligned for control.

[0012] It further includes a control mechanism for keeping the controller in the lowered position or the raised position. The main body housing includes a mounting seat for mounting the controller. The control mechanism includes a first elastic member, a second elastic member, a locking member, an unlocking member and a locking tongue. The first elastic member is used to drive the controller to move to the raised position. The locking tongue is horizontally movably arranged on the lifting rod between a locking position and a release position. The locking member is arranged on the mounting seat and has a hook portion that cooperates with the locking tongue. When the locking tongue in the locking position abuts below the hook portion, the upward movement of the lifting rod can be restricted. The second elastic member is used to drive the locking tongue to move to the locking position. The unlocking member moves up and down between an unlocking position and a standby position. The unlocking member has a lifting portion that cooperates with the locking tongue. The cooperation between the locking tongue and the lifting portion can drive the unlocking member to move to the unlocking position where it abuts against the hook portion. The unlocking member in the standby position is away from the hook portion. In this way, the controller can be kept in the raised position or the lowered position through the control mechanism, which is convenient to operate, and the structure of the control mechanism is simple, with low manufacturing cost and convenient assembly.

[0013] The lifting portion has a first guiding inclined surface for guiding the locking tongue to move to the release position to cross over the hook portion, and the hook portion has a second guiding inclined surface for guiding the locking tongue to move below the hook portion.

[0014] The locking member comprises a rod body and a hook portion, the rod body is fixedly arranged on the mounting seat, the unlocking member is a tubular structure movably sleeved on the rod body, the lifting portion is a first annular structure arranged on the outer circumferential surface of the upper end of the unlocking member, and the hook portion is a second annular structure arranged on the outer circumferential surface of the upper end of the rod body, the outer circumference of the first annular structure is inclined upward and outward to form the first guiding inclined surface, and the outer circumference of the second annular structure is inclined downward and outward to form the second guiding inclined surface. During operation, if the locking tongue is located above the locking member, only the controller needs to be pressed down, and the locking tongue can cooperate with the second guiding inclined surface to move to the bottom of the hook portion, so that the controller remains in the lowered position. When the controller needs to be switched back to the raised position, since the unlocking member is movably arranged, only the controller needs to be pressed down further, the locking tongue passes over the lifting portion, and the downward pressing force is released. Under the elastic member of the first elastic member, the locking tongue drives the unlocking member to rise, and finally passes over the unlocking member and the locking member through the first guiding inclined surface, and the controller can be driven to the raised position by the first elastic member.

[0015] The first elastic member is a compression spring compressed between the lifting rod and the mounting seat. The mounting seat is provided with a spring mounting rod for sleeve-mounting the compression spring. The lifting rod is formed with a clearance gap for avoiding the spring mounting rod. The clearance gap is larger than the diameter of the spring mounting rod and smaller than the diameter of the compression spring. In this way, the compression spring can be well compressed between the lifting rod and the mounting seat and will not pass through the clearance gap. The lifting rod can pass through the clearance gap, so that the lifting rod can move up and down smoothly.

[0016] The mounting seat comprises a guide hole for guiding the lifting and lowering of the lifting rod.

[0017] The lower end of the lifting rod is formed with a tube body for the rod body to be inserted, and the lifting rod is formed with a wire passing channel, which is located on the outside of the tube body. One end of the wire passing channel is connected to the control box, and the other end passes through the lower end of the lifting rod. The tube body can be inserted into the rod body so that the lock tongue can cooperate smoothly with the locking piece and the unlocking piece, and the wire passing channel can enable the controller to be well wired.

[0027] Referring to Figures 1 to 9 As shown, a stepper includes a main machine housing 1 and a controller 2. The controller 2 is disposed on the main machine housing 1 so as to be liftable between a raised position and a lowered position. When the controller 2 is in the raised position, the controller 2 protrudes outside the main machine housing 1. When the controller 2 is in the lowered position, the controller 2 sinks into the main machine housing 1. In this way, when the controller 2 is in the raised position, it is convenient for the user to observe and operate the controller 2. After use, the controller 2 can also be set back to the lowered position, making the operation more flexible, facilitating storage, improving space utilization rate, and saving packaging and transportation costs. The above-described sinking means that the controller 2 descends to be completely flush with the main machine housing 1 or mostly sinks into the main machine housing 1 with only a part outside. When the controller 2 is in the raised position, the controller 2 can serve as a handle to facilitate the movement of the stepper. The controller 2 includes a lifting rod 22 and a control box 21. The lifting rod 22 is disposed in the main machine housing 1 so as to be liftable and movable. The control box 21 is disposed at the upper end of the lifting rod 22. A control circuit is disposed in the control box 21. A control panel 211 for the user to operate and set the stepper is disposed on the top surface of the control box 21. Buttons and a display screen are disposed on the control panel 211 for controlling and observing the working state of the stepper. When the controller 2 is in the lowered position, the top surface of the control box 21 is smoothly transitioned with the outer surface of the main machine housing 1. In this way, when the user exercises on the stepper, setting the controller 2 in the lowered position, the control box 21 will not protrude to affect the user's exercise and can also be convenient for storage, improving space utilization rate.

[0028] The control box 21 is rotatably disposed at the upper end of the lifting rod 22 through a pivot shaft 23. The pivot shaft 23 is perpendicular to the length direction of the control box 21. In this way, when the controller 2 is in the raised position, the control box 21 can be tilted forward and backward to adjust the angle, so as to adapt to different use angles of the user.

[0029] It further includes a control mechanism for keeping the controller 2 in the lowered position or the raised position. The main body housing 1 includes a mounting seat 11 for mounting the controller 2. The control mechanism includes a first elastic member 33, a second elastic member 34, a locking member 31, an unlocking member 35, and a locking tongue 32. The first elastic member 33 is used to drive the controller 2 to move to the raised position. The locking member 31 is arranged on the mounting seat 11. The locking member 31 includes a rod body 313 and a hook portion 311. The rod body 313 is fixedly arranged on the mounting seat 11. The unlocking member 35 is a tubular structure movably sleeved on the rod body 313. A first annular structure is formed on the outer peripheral surface of the upper end of the tubular structure. The first annular structure is inclined upward and outward to form a first guiding slope 351. The hook portion 311 is a second annular structure arranged on the outer peripheral surface of the upper end of the rod body 313. The locking tongue 32 is arranged on the lifting rod 22 so as to be laterally movable between a locking position and a release position. Two convex and hollow mounting portions 221 are formed on the left and right sides of the lifting rod 22. The locking tongue 32 is arranged in the mounting portion 221, and the front and rear ends of the mounting portion 221 are open. The opening at the rear end allows the rear end of the locking tongue 32 to extend out. In this way, when the locking tongue 32 is squeezed, the opening at the rear end of the mounting portion 221 can play a role of making way. The opening at the front end of the mounting portion 221 allows the locking tongue 32 to extend out and cooperate with the locking member 31. The locking tongue 32 includes an integrally formed main body and an abutting portion. The abutting portion is located at the front end of the main body and is larger than the main body. The second elastic member 34 is a second compression spring. The second compression spring is sleeved on the main body and compressed between the abutting portion and the mounting portion 221. When the locking tongue 32 in the locking position is located below the hook portion 311 and abuts against the hook portion 311, it can limit the upward movement of the lifting rod 22. The second elastic member 34 is used to drive the locking tongue 32 to move to the locking position. The unlocking member 35 moves up and down between an unlocking position and a standby position. The unlocking member 35 can be driven by the locking tongue 32 to move to the unlocking position where it abuts against the hook portion 311. The unlocking member 35 in the standby position is away from the hook portion 311. The unlocking member 35 has a lifting portion 352 that cooperates with the locking tongue 32. The lifting portion 352 has a first guiding slope 351 for guiding the locking tongue 32 to cross over the hook portion 311. The first guiding slope 351 extends upward and outward. The locking tongue 32 can cooperate with the lifting portion 352 to drive the unlocking member 35 to move to the unlocking position. In this way, the controller 2 can be kept in the raised position or the lowered position through the control mechanism, which is convenient to operate. Moreover, the structure of the control mechanism is simple, the manufacturing cost is low, and the assembly is convenient.

[0030] The hook portion 311 has a second guiding inclined surface 312 that guides the locking tongue 32 to move below the hook portion 311. Specifically, this inclined surface extends downward and outward. The locking tongue 32 has a third guiding inclined surface 321 that extends downward, backward, and downward. During operation, if the locking tongue 32 is located above the locking member 31, only by pressing down the controller 2, the locking tongue 32 moves into contact with the locking member 31. The locking tongue 32 is squeezed by the locking member 31, and the rear end of the locking tongue 32 extends outward. And the cooperation of the third guiding inclined surface 321 and the second guiding inclined surface 312 enables the locking tongue 32 to cross over the hook portion 311. Under the elastic action of the second elastic member 34, the locking tongue 32 moves to the locking position, located below the hook portion 311 and abuts against the hook portion 311, keeping the controller 2 in the lowered position. When it is necessary to switch the controller 2 back to the raised position, since the unlocking member 35 is movably arranged, only by continuing to press down the controller 2, the third guiding inclined surface 321 is squeezed by the upper end of the lifting portion 352, causing the locking tongue 32 to move to the release position. The locking tongue 32 can then cross over the upper end of the unlocking member 35. At this time, release the pressing force. Under the elastic action of the first elastic member 33, the locking tongue 32 drives the unlocking member 35 to rise. Finally, through the first guiding inclined surface 351, the locking tongue 32 crosses over the unlocking member 35 and the locking member 31. Without any obstruction, the controller 2 can be driven by the first elastic member 33 to the raised position.

[0031] The first elastic member 33 is a first compression spring compressed between the lifting rod 22 and the mounting base 11. The mounting base 11 is provided with a spring mounting rod 111 for sleeving the first compression spring. A relief notch 222 for avoiding the spring mounting rod 111 is formed on the lifting rod 22. The relief notch 222 is larger than the diameter of the spring mounting rod 111 and smaller than the diameter of the first compression spring. In this way, the first compression spring can be well compressed between the lifting rod 22 and the mounting base 11 and will not pass through the relief notch 222, while the lifting rod 22 can pass through the relief notch 222, enabling the lifting rod 22 to move smoothly up and down. The mounting base 11 further includes a base 13 provided at the lower end. A connecting column 131 for positioning the spring mounting rod 111 and the first compression spring is formed on the base 13. During installation, the first compression spring is sleeved on the spring mounting rod 111, and then the spring mounting rod 111 is connected to the connecting column 131. And an installation hole 132 is formed on the base 13. A plugging portion 314 that cooperates with the installation hole 132 is formed at the bottom of the rod body 313. The plugging portion 314 is inserted into the installation hole 132 to achieve the fixed connection between the rod body 313 and the mounting base 11. The mounting base 11 is formed with a guiding hole 112 for guiding the lifting of the lifting rod 22 to ensure the accurate lifting of the lifting rod 22.

[0032] A tube body into which the lower end of the lifting rod 22 is formed for inserting the rod body 313 is formed with a jack 223. The lifting rod 22 is formed with a wire passing channel 224 which is located outside the tube body. One end of the wire passing channel 224 communicates with the control box 21, and the other end penetrates through the lower end of the lifting rod 22. The rod body 313 can be inserted into the jack 223 to enable the locking tongue 32 to cooperate smoothly with the locking member 31 and the unlocking member 35, and the wire passing channel 224 can enable the controller 2 to achieve wiring well.

[0033] It also includes a stepper body, a stepper base and a footrest part, all of which are publicly known prior arts and will not be described in detail here.

[0034] When the controller 2 is in the lowered position, referring to Figures 1 to 3 as shown, at this time the controller 2 is lowered until its top surface is flush with the outer surface of the main body housing 1. The locking tongue 32 pops out under the action of the second elastic member 34 and abuts against the bottom of the hook portion 311 so that the lifting rod 22 cannot rise. At this time, the second elastic member 34 is compressed, and the unlocking member 35 descends to the standby position under its own gravity; when it is necessary to switch the controller 2 to the raised position, press down the control box 21 to make the locking tongue 32 descend to cross over the lifting portion 352 and be located below the lifting portion 352, and then release the control box 21 to make the controller 2 rise under the action of the first elastic member 33. During the rising process, the lifting portion 352 and the locking tongue 32 cooperate to drive the unlocking member 35 to move to the unlocking position against the lower part of the hook portion 311. At this time, the unlocking member 35 cannot continue to rise. Under the action of the first elastic member 33, the locking tongue 32 continues to rise with the lifting rod 22 and moves to the release position under the guidance of the first guiding inclined surface 351 and crosses over the lifting portion 352 and the hook portion 311, and then makes the controller 2 rise to the raised position, as Figures 4 to 6 shown; when it is necessary to switch the controller 2 in the raised position to the lowered position, press down the control box 21, and the locking tongue 32 descends to be guided to the release position by the second guiding inclined surface 312, and then crosses over the hook portion 311. Under the action of the second elastic member 34, the locking tongue 32 switches to the locking position and is located below the hook portion 311 and abuts against the lower part of the hook portion 311, and the lifting rod 22 is restricted from rising, and the control box 21 can be in the lowered position flush with the outer peripheral surface of the main body housing 1.

[0035] The above is only the preferred embodiment of the present invention, and thus cannot limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the specification should still fall within the scope covered by the patent of the present invention.
