Description

Technical Field

[0001] The utility model relates to the field of stepper structures, in particular to a waist-twisting stepper capable of adjusting a fitness mode by locking with a latch. Background Art

[0002] To meet the needs of modern people for moderate exercise despite their busy lives, fitness equipment industry professionals have developed a variety of fitness equipment, such as steppers, that are easy to use and closely simulate outdoor exercise. When using a stepper, the user places their feet on two pedals, applying downward force with each foot in turn, causing the pedals to move up and down alternately, thereby achieving the desired effect of simulating walking and achieving a fitness routine.

[0003] Current steppers are already capable of achieving a variety of exercise modes such as stepping and twisting the waist, such as a rotating waist-twisting stepper disclosed in application number 201620711043.5 and a waist-twisting stepper disclosed in application number 202221651724.9. Taking the prior patent with application number 201620711043.5 as an example, this type of stepper connects the swing arm connecting the pedals (equivalent to the upper and lower rocker arms 9) to the rotating seat (equivalent to the rotating disk 5 and the rotating fixed seat 6). When the pedal is stepped down, the swing of the swing arm causes the two pedals to move up and down alternately, and the rotation of the rotating seat is driven by the pedal to achieve the waist-twisting exercise mode.

[0004] However, when only stepping is required, the rotating seat will inevitably rotate, making it impossible to achieve stable stepping. Moreover, when only twisting the waist is required, the swing arm cannot be fixed, and the two pedals for standing are not stable enough to achieve a smooth twisting of the waist. Therefore, this type of waist-twisting stepper cannot lock the swing arm and the rotating seat, so it has certain drawbacks when used for fitness exercise. Utility Model Content

[0005] In view of the deficiencies in the above background technology, the present invention provides a waist-twisting stepper that can adjust the fitness mode by locking with a latch.

[0006] The utility model adopts the following technical solutions:

[0007] A waist-twisting stepper with a locking mechanism for adjusting a fitness mode by means of a latch, the waist-twisting stepper comprising:

[0008] a base, on which a rotating shaft is fixed;

[0009] A rotating seat, wherein the rotating seat sleeve rotates on the rotating shaft;

[0010] An upper swing frame, wherein the middle of the upper swing frame is pivotally connected to the middle of the rotating seat, so that both ends of the upper swing frame swing relative to the base and the rotating seat;

[0011] A lower swing frame, wherein the rotating seat is pivotally connected to the lower swing frame on both sides below the upper swing frame, so that the two lower swing frames can swing relative to the base and the rotating seat;

[0012] A pedal, both ends of the upper swing frame and the two lower swing frames are connected to the pedal, a pivot member is fixed to the bottom of the pedal, and the upper and lower ends of the pivot member are pivotally connected to the end of the upper swing frame and the end of the lower swing frame respectively;

[0013] A latch having two rods;

[0014] A first limiting hole is provided in the middle of the upper swing frame, and a second limiting hole is provided on the rotating seat. When the upper swing frame rotates until the two pedals are parallel, the two insertion rods of the latch can be respectively inserted into the first limiting hole and the second limiting hole.

[0015] A positioning plate is fixed on one side of the rotating seat, and the positioning plate has a third limiting hole. A connecting plate is fixed on one side of the base, and the connecting plate has a fourth limiting hole. When the rotating seat is rotated until the upper swing frame and the base are flush, the insertion rod of the pin can be inserted into the third limiting hole and the fourth limiting hole in sequence.

[0016] In a possible implementation, the upper swing frame includes an upper swing arm and a reinforcement member, the reinforcement member is a triangular structure, the first limiting hole is arranged in the middle of the reinforcement member, and the symmetrical two side inclined surfaces of the reinforcement member respectively fix the two upper swing arms.

[0017] In one possible implementation, the upper swing frame also includes an upper sleeve, and the two upper swing arms are simultaneously fixed to the upper sleeve at a position below the reinforcement. An upper rotating shaft is fixed above the rotating seat, and the upper sleeve is adapted to be fitted outside the upper rotating shaft, so that the upper swing frame swings around the upper rotating shaft as the axis.

[0018] In one possible implementation, a reduced diameter portion is provided above the rotating shaft, a bearing is provided on the outer sleeve of the reduced diameter portion, and a spiral connection screw is adapted for the top of the reduced diameter portion. A rotating sleeve is fixed below the rotating seat, the bearing is embedded in the rotating sleeve with an interference fit, and the screw passes downward through the rotating sleeve until the screw and the rotating shaft are spirally connected.

[0019] In a possible implementation, the base fixes a buffer pad below the corresponding pivot member, and when the pedal swings downward to under the base, it presses against the buffer pad.

[0020] In one possible implementation, the waist-twisting stepper also includes a damper, which is connected under both pedals. The damper has a piston rod, and the end of the damper that is telescoped away from the piston rod is pivotally connected to the rotating seat, and the piston rod end of the damper is pivotally connected to the pivot member.

[0021] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: In the structure of the present invention, if the rotating seat needs to be fixed relative to the base and cannot rotate, the plug rod of the latch can be inserted into the third limiting hole of the rotating seat and the fourth limiting hole of the base to lock the rotating seat and prevent it from rotating, so that the fitness exercise of stepping left and right can be performed stably. If the upper swing frame needs to remain balanced and motionless relative to the base, the two plug rods of the latch can be inserted into the first limiting hole of the reinforcement and the second limiting hole of the rotating seat respectively, thereby preventing the upper swing frame from swinging relative to the rotating seat, thereby keeping the two pedals parallel and fixed. At this time, the fitness exerciser can stand steadily on the two pedals and drive the rotating seat to rotate relative to the base, so as to stably perform the fitness exercise of twisting the waist. As can be seen from this, the present invention can overcome the defect of the upper swing frame and rotating seat of the stepper that cannot be locked by inserting the latch, and can safely and stably perform various exercise modes such as stepping left and right and twisting the waist.

[0033] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0034] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0035] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0036] The utility model provides a waist twisting stepper that can adjust the fitness mode by locking the latch 6. Figures 1 to 4 As shown, the waist-twisting stepper includes a base 1, a rotating base 2, an upper swing frame 3, and a lower swing frame 4. A rotating shaft 11 is fixed to the base 1, and the rotating base 2 is sleeved on the rotating shaft 11 and rotates. The middle of the upper swing frame 3 is pivotally connected to the middle of the rotating base 2, so that both ends of the upper swing frame 3 swing relative to the base 1 and the rotating base 2. The rotating base 2 is pivotally connected to the lower swing frames 4 on both sides below the upper swing frame 3, so that both lower swing frames 4 swing relative to the base 1 and the rotating base 2. Both ends of the upper swing frame 3 and the two lower swing frames 4 are connected to the pedals 5. Specifically, the upper and lower ends of the pivot member 51 fixed at the bottom of the pedal 5 are pivotally connected to the end of the upper swing frame 3 and the end of the lower swing frame 4, respectively. The pivot structure in this embodiment can be that the pivot bolt 22 passes through the two pivoted parts and is connected to the nut, so that the two pivoted parts rotate relative to each other with the pivot bolt 22 as the axis.

[0037] Please refer to the attached Figure 9The pivotal member 51, one side of the upper swing frame 3, the lower swing frame 4, and the rotating base 2 in the above structure are connected to form a quadrilateral connecting rod structure, so that when the exerciser stands on the two pedals 5 and alternately steps on the pedals 5 on the left and right sides of the base 1, the pedals 5 can move smoothly downward and upward. Specifically, when the exerciser steps on the left pedal 5, the left side of the upper swing frame 3 and the lower swing frame 4 swing downward, while the right side of the upper swing frame 3 is lifted upward. Then, the exerciser steps on the right pedal 5, causing the right side of the upper swing frame 3 and the other lower swing frame 4 to swing downward, while the left side of the upper swing frame 3 is lifted upward. This reciprocating movement forms a stepping motion.

[0038] Continue to refer to the attached Figure 2 and 3 The base 1 is fixed with a buffer pad 12 below the corresponding pivot member 51. When the pedal 5 swings downward to under the base 1, it presses against the buffer pad 12. In this structure, the buffer pad 12 can play a role of buffering when the fitness person steps on the pedal 5 to approach the base 1, preventing the pivot member 51 at the bottom of the pedal 5 from directly hitting the base 1 and generating a large impact force, causing the base 1 to be displaced, and at the same time, it can also prevent the pivot member 51 from damaging the base 1.

[0039] In addition, the waist twisting stepper also includes a damper 7. The damper 7 is connected to the bottom of both pedals 5. The damper 7 has a piston rod 71. Preferably, the damper 7 can be a hydraulic damper 7 or a spring damper 7. The end of the damper 7 that is away from the piston rod 71 is pivotally connected to the rotating seat 2. The end of the piston rod 71 of the damper 7 is pivotally connected to the upper swing member. When the fitness person steps on the pedal 5 and drives one side of the upper swing frame 3 downward, the piston rod 71 of the damper 7 can be driven to retract inward. During this process, the damper 7 can form resistance to the downward swing of the lower swing arm, thereby forming resistance to the feet pressing down on the pedals 5 during exercise, thereby increasing the intensity of fitness training. In addition, refer to the attached Figure 6 The lower swing frame 4 includes two plates 41 and a lower sleeve 42 arranged between the two plates 41. Specifically, when the two ends of the lower swing frame 4 are respectively connected to the pivot member 51 and the rotating seat 2, the lower sleeve 42 is respectively arranged at the two ends between the two plates 41, and the pivot bolt 22 is then passed through the two plates 41 and the lower sleeve 42 and the pivot member 51 or the side of the rotating seat 2 to form the overall structure of the lower swing member, and a gap is formed between the two plates 41 for setting the damper 7. This structure allows the piston rod 71 of the damper 7 to be connected to the upper swing frame 3 through the giving way of the lower swing frame 4. Compared with the way in which the piston rod 71 of the damper 7 is connected to the lower swing frame 4, it is beneficial to reduce the overall height of the utility model and facilitate storage and transportation.

[0040] As attached Figure 4 and 5As shown, the upper swing frame 3 includes an upper swing arm 31, a reinforcement 32, and an upper sleeve 33. The front of the reinforcement 32 is an isosceles triangle structure, with a first limiting hole 301 located in the middle of the reinforcement 32. The symmetrical inclined surfaces of the reinforcement 32 are fixedly connected to the two upper swing arms 31, respectively. The upper sleeve 33 is fixed below the reinforcement 32, and both upper swing arms 31 are fixed to the upper sleeve 33 below the reinforcement 32. This creates a structure in which the upper swing frame 3 has symmetrically inclined upper swing arms 31 on both sides of the upper sleeve 33. When the exerciser steps on the pedal 5, the upper swing arm 31 on one side of the upper swing frame 3 and the lower swing frame 4 located below it swing downward, while the upper swing arm 31 on the other side and the lower swing frame 4 located below it swing upward. In addition, the upper rotating shaft 21 is fixed above the rotating seat 2, and the upper sleeve 33 is adapted to fit outside the upper rotating shaft 21, so that the upper swing frame 3 swings around the upper rotating shaft 21 as the axis. This can form the above-mentioned structure in which the fitness user steps on the pedal 5 to cause the upper swing frame 3 to swing relative to the base 1 and the rotating seat 2.

[0041] As attached Figure 2 and 7 As shown, the rotating seat 2 is provided with a second limiting hole 201 on the side surface above the rotating sleeve 23. The latch 6 has two insertion rods 61. Specifically, as shown in the accompanying drawings, the latch 6 is C-shaped as a whole, with two insertion rods 61 at both ends.

[0042] When the upper swing arm 31 rotates until the two pedals 5 are parallel, Figure 1 、 4 As shown in Figure 5, the two insertion rods 61 of the latch 6 can be inserted into the first limiting hole 301 and the second limiting hole 201 respectively, thereby restricting the upper swing frame 3 so that the upper swing frame 3 cannot swing relative to the rotating base 2, thereby keeping the two pedals 5 in a parallel and fixed state. At this time, the fitness user standing on the two pedals 5 cannot move the pedals 5 up or down, forming a locking effect of the pedals 5 relative to the base 1 through the latch 6. In addition, since the rotating base 2 can rotate relative to the base 1, when the fitness user stands on the two pedals 5, they can apply force to the pedals 5 with their feet to drive the rotating base 2 to rotate relative to the base 1, thereby performing a waist twisting exercise.

[0043] The structure of the rotating seat 2 connected to the base 1 can be as shown in the attached Figure 7 and 8As shown, a reduced diameter portion 111 is positioned above the rotating shaft 11. A screw 25 fits on the top of this portion, and a bearing 24 is positioned around the outside of this portion. A rotating sleeve 23 is secured to the bottom of the rotating base 2. Bearing 24 is inserted into this sleeve with an interference fit. Screw 25 passes downward through a connection hole on the top surface of the sleeve 23 and is screwed onto the rotating shaft 11, securing it securely. A clearance exists between the screw head and the top surface of the sleeve 23. This mounting arrangement creates a structure that constrains the rotating base 2 to rotate on the base 1 about the rotating shaft 11.

[0044] Please refer to the attached Figures 2 to 4 A positioning plate 26 is also fixed on one side of the rotating seat 2, and the positioning plate 26 has a third limiting hole 202. A connecting plate 13 is fixed on one side of the base 1, and the connecting plate 13 is provided with a fourth limiting hole 101. When the rotating seat 2 rotates until the upper swing frame 3 and the base 1 are flush, the insertion rod 61 of the latch 6 can be inserted into the third limiting hole 202 and the fourth limiting hole 101 in sequence, thereby jamming the rotating seat 2, making the rotating seat 2 unable to rotate relative to the base 1, thereby locking the rotation direction of the pedal 5 relative to the base 1 through the latch 6.

[0045] In addition, as attached Figure 1 and 3 As shown, fillet bars 8 can be provided on both sides of the front of the base 1. During exercise, two bars 8 can be held by both hands to help stabilize the body. The structure in which the fillet bars 8 are provided on the front of the base 1 can be that sleeves 14 are provided on both sides of the front of the base 1. One end of the fillet bar 8 is directly inserted downward into the sleeve 14, and a fixing bolt 141 can be screwed onto one side of the sleeve 14. By screwing the fixing bolt 141 into the sleeve 14 and pressing it against the fillet bar 8, the end of the fillet bar 8 can be fixed in the sleeve 14. When the fillet bar 8 needs to be used alone, the fixing bolt 141 is unscrewed from the sleeve 14, and the fillet bar 8 can be pulled out for use.

[0046] In summary, in the structure of the present invention, the upper swing frame 3 swings relative to the rotating base 2 so that the pedals 5 on both sides thereof can form an alternating up-and-down movement as the upper swing frame 3 swings, so that the fitness person standing on the two pedals 5 can do the following Figure 9 The fitness action of stepping left and right as shown in the figure, and combined with the rotation of the rotating seat 2 relative to the base 1, the fitness person standing on the two pedals 5 can drive the rotating seat 2 to rotate to form the fitness action as shown in the figure. Figure 10The front and rear pedals 5 are shown as fitness exercises. If the rotating seat 2 needs to be fixed relative to the base 1 and cannot rotate, the plug rod 61 of the latch 6 is inserted into the third limiting hole 202 of the rotating seat 2 and the fourth limiting hole 101 of the base 1, so that the rotating seat 2 can be stuck and cannot rotate. At this time, the fitness exercise of stepping left and right can be performed. If the upper swing frame 3 needs to remain balanced and motionless relative to the base 1, the two plug rods 61 of the latch 6 can be inserted into the first limiting hole 301 of the reinforcement 32 and the second limiting hole 201 of the rotating seat 2 respectively, so that the upper swing frame 3 cannot swing relative to the rotating seat 2, thereby keeping the two pedals 5 in a parallel and fixed state. At this time, as shown in the attached figure, Figure 11 As shown, the exerciser can stand on the two pedals 5 with both feet stable to drive the rotating seat 2 to rotate relative to the base 1 to perform waist twisting exercise. As can be seen, the utility model can prevent the pedals 5 from moving up or down by inserting the latch 6, so that the pedals 5 can be locked in the lifting direction and the rotation direction relative to the base 1 by inserting the latch 6. This locking method is relatively reliable and very convenient to operate.

[0047] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
