Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, specifically to a seated hip-lifting training machine. Background Technology

[0002] A hip lift machine is a fitness device specifically designed to exercise the gluteal muscles. It typically includes a movable backboard, a seat in front of the backboard, and an abdominal bar. During exercise, the user's back is pressed against the backboard, while the abdominal bar gently presses against the user's abdomen. The abdominal bar helps the user maintain a neutral spine position during exercise, reducing compensatory movements in the lower back and thus enhancing the effectiveness of the hip lift.

[0003] Chinese patent document (CN223009732U) discloses a glute bridge trainer. A back support is rotatably connected to the machine body. A support and seat are set in front of the back support, and an abdominal pressure device is rotatably connected to the support. The end of the abdominal pressure device is engaged with the positioning post on the support through multiple positioning holes on the mating part to achieve position adjustment of the abdominal pressure device. A barbell plate is suspended on the first crossbar on the support to provide training resistance when the support is raised with the back support. At the same time, a handle on the support is rotatably engaged with one side of the support and a switch is provided between the handle and the other side of the support, so that the abdominal pressure device and the handle can be flipped open around one side of the support, which facilitates the user to enter and exit the seat and adjust the position of the abdominal pressure device according to body shape.

[0004] However, this type of hip-lifting training machine has the following drawbacks: First, fitness enthusiasts of different body types need to pull out the positioning column and re-align and reconnect it when adjusting the position. If the adjustment is not in place, the above actions must be repeated. Furthermore, entering and exiting require flipping the handle, the abdominal pressure device, and the operating switch, which is inconvenient. Second, the position adjustment of the abdominal pressure device relies solely on the positioning column and multiple positioning holes on the mating parts, which limits the adjustment range. Summary of the Invention

[0005] The purpose of this invention is to provide a seated hip-lifting training machine that allows for easy adjustment of the relative position of the abdominal compression device and the abdomen, with a wide adjustment range, and also facilitates easy entry and exit from the seat.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The seated hip lift training machine includes the machine body, resistance mechanism, abdominal compression mechanism, pedals, seat cushion, and shoulder pads; The pedals, seat cushion, and shoulder pads are arranged sequentially at the front and back of the machine body. The abdominal compression mechanism includes an abdominal compression roller and a first mounting base, a second mounting base, and a counterweight arm located on one side of the machine body. The first mounting base and the counterweight arm are both hinged to the machine body and are connected together by a spring pin and a vertically arranged positioning hole plate. A gas spring for swinging the front part of the first mounting base upward is also connected between the first mounting base and the counterweight arm. The second mounting base is provided with a first mounting shaft and a second mounting shaft. The first mounting shaft is rotatably engaged with the first mounting base, and a limiting component is provided between the first mounting shaft and the first mounting base to limit the swing range of the two. The abdominal pressure roller is rotatably sleeved outside the second mounting shaft and rotates around the first mounting shaft. A handrail is also fixedly provided on the second mounting shaft, and an operating component for pulling out the elastic pin is provided between the handrail and the elastic pin. The counterweight arm is connected to the resistance mechanism.

[0007] Preferably, the front part of the first mounting base has a cylindrical mounting cavity, and the limiting component includes a limiting pin fixedly mounted on the first mounting shaft and extending radially along the first mounting shaft, and a limiting arc hole opened on the cylindrical mounting cavity and arranged circumferentially along the cylindrical mounting cavity, wherein the limiting pin is slidably fitted in the limiting arc hole.

[0008] Preferably, the central angle of the limiting arc hole is 70°-120°.

[0009] Preferably, the elastic pin is installed at the front of the first mounting base, and the elastic pin swings up and down with the first mounting base, corresponding to a plurality of insertion holes arranged at height intervals on the positioning hole plate, and the positioning hole plate is fixedly installed on the counterweight arm.

[0010] Preferably, the operating component includes a pull rope, a swing arm, and an operating lever. The middle part of the swing arm is hinged to the handrail near the second mounting base. One end of the pull rope is movably connected to the bottom end of the swing arm, and the other end of the pull rope is connected to a spring pin. One end of the operating lever is movably connected to the top end of the swing arm, and the other end of the operating lever extends into the handrail and is exposed. The operating lever is located inside the handrail near the second mounting base, and a return spring is sleeved on the outside of the operating lever.

[0011] Preferably, the second mounting base has a through hole at the position corresponding to the swing arm, the bottom end of the swing arm extends into the interior of the second mounting base through the through hole, and the pull rope passes out of the second mounting base.

[0012] Preferably, the handrail includes a first handrail and a second handrail, which are respectively located on the second mounting shaft on both sides of the axial direction of the pressure roller, and the first handrail is close to the second mounting seat.

[0013] Preferably, an angle adjustment mechanism is connected between the pedal and the body.

[0014] Preferably, a height adjustment mechanism is connected between the seat cushion and the body.

[0015] Preferably, the resistance mechanism is a barbell plate or an electric resistance mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The abdominal compression mechanism of this invention includes a first mounting base, a second mounting base, and a counterweight arm. The first mounting base and the counterweight arm are connected as one unit by a positioning plate and a spring pin, and each has a pivot point that allows it to rotate up and down. The height of the first mounting base can be adjusted by the positioning plate and the spring pin, thereby adjusting the height and front-back position of the abdominal compression roller. At the same time, the second mounting base adopts a dual-axis swing shaft structure with a limited swing range. The first mounting shaft rotates in conjunction with the mounting base as the swing fulcrum of the swing base. It can swing freely within the limited swing range due to the limitation of the positioning component. The combination of the positioning plate and the spring pin greatly improves the adjustment range and adjustment accuracy of the abdominal compression roller.

[0017] The abdominal roller of the present invention is rotated and sleeved on the second mounting shaft. During the abdominal training process, it will rub and roll against the abdomen, which will play a certain massage and kneading function. At the same time, since the second mounting seat swings freely, it can reduce the pressure on the abdomen of the exerciser. Attached Figure Description

[0027] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0028] like Figures 1-8 As shown, this embodiment provides a seated hip-lifting training machine, including a body 100, a resistance mechanism 200, an abdominal compression mechanism, a pedal 101, a seat cushion 102, and a shoulder pad 103. The pedal 101, seat cushion 102, and shoulder pad 103 are arranged sequentially on the body 100. An angle adjustment mechanism connects the pedal 101 to the body 100, and a height adjustment mechanism connects the seat cushion 102 to the body 100. The mounting position and angle of the shoulder pad 103 to the body 100 are fixed and cannot be adjusted. The angle adjustment mechanism can refer to the pedal and base adjustment structure in CN223009732U. The height adjustment mechanism adopts a socket-spring pin combination structure, which is a conventional structure.

[0029] The abdominal compression mechanism includes an abdominal compression roller 40 and a first mounting base 10, a second mounting base 20 and a counterweight arm 30 located on one side of the machine body 100. The first mounting base 10 and the counterweight arm 30 are both hinged on the machine body 100 and are connected together by a spring pin 60 and a vertically arranged positioning hole plate 50.

[0030] In this embodiment, the rear of the first mounting base 10 has a pivot point around which it can swing up and down. This pivot point is a horizontally arranged hinge axis that is movably connected to the body of the buttock-lifting training machine. A counterweight arm 30 is also hinged to the body of the buttock-lifting training machine, and the counterweight arm 30 is arranged adjacent to the first mounting base 10. Preferably, the hinge center lines of the counterweight arm 30 and the first mounting base 10 are coaxial.

[0031] The positioning plate 50 is fixedly installed on the counterweight arm 30 by conventional methods such as welding and extends vertically upward. The positioning plate 50 has multiple insertion holes 51 spaced apart in the height direction. The elastic pin 60 is installed on the front of the first mounting base 10 by a pin seat 14 welded to the first mounting base 10. The elastic pin 60 swings up and down with the first mounting base 10 and corresponds to the multiple insertion holes 51 spaced apart in height on the positioning plate 50. When the elastic pin 60 is inserted into one of the insertion holes 51, the counterweight arm 30 is connected to the first mounting base 10. Thus, the up and down swing of the first mounting base 10 will drive the counterweight arm 30 to swing up and down, and the counterweight arm 30 is connected to the counterweight system to provide training resistance.

[0032] The elastic pin 60 is a common mechanical component in the prior art. It includes a pin rod and a spring-loaded component. When the pin rod is not subjected to a pulling force, the spring-loaded component pushes the pin rod toward the insertion hole 51. Under the pulling force, the spring-loaded component will overcome the resistance and displace the pin rod away from the insertion hole 51.

[0033] In this embodiment, the second mounting base 20 is installed at the front of the first mounting base 10. The second mounting base 20 includes a base body, a first mounting shaft 21 located at the lower end of the base body, and a second mounting shaft 22 located at the upper end of the base body. The first mounting shaft 21 and the second mounting shaft 22 are parallel to each other and arranged horizontally. The first mounting shaft 21 and the second mounting shaft 22 can be round shafts and welded to the base body. The base body is a hollow structure.

[0034] The first mounting shaft 21 is rotatably engaged with the first mounting base 10. Specifically, the front part of the first mounting base 10 has a cylindrical mounting cavity, which is used to rotatably mount the first mounting shaft 21. The cylindrical mounting cavity can be designed by welding a mounting cylinder 11 to the front part of the first mounting base 10, and the mounting cylinder 11 is a hollow cylindrical structure. A rolling bearing 211 is press-fitted between the first mounting shaft 21 and the mounting cylinder 11 of the first mounting base to achieve rotatable engagement. The base body and the second mounting shaft 22 both swing back and forth relative to the first mounting base 10 around the first mounting shaft 21.

[0035] The abdominal pressure roller 40 is rotatably sleeved outside the second mounting shaft 22 and rotates around the first mounting shaft 21. The abdominal pressure roller 40 is located above the seat cushion 102. To limit the range of back-and-forth swing of the abdominal pressure roller 40, a limiting component is provided between the first mounting shaft 21 and the first mounting base 10 to limit the swing range of both. Specifically, the limiting component includes a limiting pin 212 fixedly mounted on the first mounting shaft 21 and extending radially along the first mounting shaft 21, and a limiting arc hole 12 opened on the mounting cylinder 11 and arranged circumferentially along the mounting cylinder 11. The central angle of the limiting arc hole 12 is [missing information]. The limiting pin 212 slides within the limiting arc hole 12, between 70° and 120°. Limited by the limiting component, it can swing freely within a defined range. Users do not need to pull the positioning pin or adjust the alignment; they only need to swing the abdominal roller to the appropriate position. When the limiting pin 212 slides to the bottom limit position of the limiting arc hole 12, the second mounting shaft 22 and the abdominal roller 40 on it move away from the seat. When the limiting pin 212 slides to the top limit position of the limiting arc hole 12, the second mounting shaft 22 and the abdominal roller 40 on it move closer to the seat. The seat is a component of the hip-lifting training machine, for the user to sit on, located in front of the back support.

[0036] To reduce noise or mechanical damage caused by the limit pin 212 impacting the first mounting base 10 at its upper and lower extreme positions, a buffer sleeve 213 is fixedly fitted on the outside of the limit pin 212. The buffer sleeve 213 contacts the mounting cylinder 11 instead of the limit pin 212 directly contacting the mounting cylinder 11. The limit pin 212 is a metal bolt while the buffer sleeve 213 is made of rubber and plastic material.

[0037] In this embodiment, the connection between the limiting pin 212 and the first mounting shaft 21 is as follows: The first mounting shaft 21 has a mounting hole, and a pin seat 214 is fixedly installed inside the mounting hole. The pin seat 214 has a threaded hole, and the limiting pin 212 is threaded into the pin seat 214. After assembly, both the limiting pin 212 and the buffer sleeve 213 are within the limiting arc hole 12 and will not protrude outwards from the limiting arc hole 12. A decorative piece 13 covering the limiting arc hole 12 is also provided on the outer wall of the mounting cylinder 11, which serves both decorative and aesthetic purposes and prevents accidental injury to people or objects when the limiting pin 212 rotates. Both ends of the decorative piece 13 are fixed to the mounting cylinder 11 by screws.

[0038] In this embodiment, a handrail 23 is also installed on the second mounting base 20. The handrail 23 includes a first handrail and a second handrail. The first handrail and the second handrail are respectively located on the second mounting shaft 22 on both axial sides of the pressure roller 40, and the first handrail is close to the second mounting base 20. The first handrail and the second handrail each include a connecting plate 231 and a handle 232. The connecting plate 231 is fixedly installed on the second mounting shaft 22 and extends radially. The handle 232 is fixedly installed on the radial end of the connecting plate 231 and is arranged slightly inclined relative to the second mounting shaft 22.

[0039] The operating component is used to pull the elastic pin 60 so that the elastic pin 60 is disengaged from the socket 51. The operating component includes a pull rope 73, a swing rod 72, and an operating lever 71. The middle part of the swing rod 72 is hinged to the side of the connecting plate 231 of the first handrail near the second mounting base 20 through a hinge seat and a hinge shaft. The second mounting base 20 has a through hole at the position corresponding to the swing rod 72 so that the bottom end of the swing rod 72 extends into the second mounting base 20. One end of the pull rope 73 is movably connected to the bottom end of the swing rod 72, and the other end of the pull rope 73 passes through the second mounting base 20 and extends to connect to the elastic pin 60. One end of the operating lever 71 is movably connected to the top end of the swing rod 72, and the other end of the operating lever 71 extends into the handle 232 of the first handrail and is exposed. The operating lever 71 is located inside the handle 232 of the first handrail, and a return spring 74 is sleeved on the outside of the operating lever 71. The end of the operating component connected to the spring pin 60 serves as the pull end of the operating component, and the end of the operating component exposed from the handle 232 of the first handrail serves as the operating end of the operating component. The operating end and the pull end are connected by a swing rod 72 and a pull rope 73. The second mounting base 20 has a hole corresponding to the position of the pull rope 73 and a fine-adjustment nut is provided at the hole. The tension of the pull rope 73 can be finely adjusted by the fine-adjustment nut.

[0040] Before training, adjust the angle of the pedal 101 and the height of the seat 102. During training, the user sits on the seat 102, steps on the pedal 101, supports the shoulder pad 103, holds the handle 232, and swings the second mounting seat 20 and the abdominal roller 40 toward the abdomen so that the abdominal roller 40 is close to the abdomen. The hip-lifting exercise raises the abdominal roller 40 upward, which in turn drives the first mounting seat 10 and the counterweight arm 30 to swing upward. The resistance mechanism 200 connected to the counterweight arm 30 provides training resistance. The resistance mechanism 200 can be a barbell plate hanging on the counterweight arm 30, or a servo electric resistance mechanism connected to the counterweight arm 30 by a steel wire rope. Before or after training, the user applies pressure to the operating end of the first armrest to overcome the elasticity of the return spring 74 and cause the swing arm 72 to rotate and tighten the pull rope 73, thereby pulling the elastic pin 60 outward and away from the insertion hole 51. At this time, the height of the first mounting seat 10, the second mounting seat 20 and the abdominal pressure roller 40 can be adjusted. A gas spring 80 is also connected between the first mounting seat 10 and the counterweight arm 30 to make the front part of the first mounting seat 10 swing upward. The gas spring 80 can help lift the first mounting seat 10 upward easily and effortlessly. After reaching the appropriate height, release the hand, the operating end resets, and the elastic pin 60 resets to maintain the height.

[0041] For aesthetic purposes, a protective cover 233 is snapped between the top of the second mounting base 20 and the side of the connecting plate 231, and the swing rod 72 is covered by the protective cover 233.
