Description

Technical Field

[0001] This invention relates to the field of fitness machinery technology, and in particular to a fitness device suitable for training the gluteus maximus. Background Technology

[0002] Fitness equipment refers to sports equipment used for physical training. Based on function, it can be divided into two main categories: single-function equipment and multi-functional equipment. The former, such as treadmills, rowing machines, and elliptical trainers, focuses on strength or cardiovascular training for specific muscle groups, while the latter integrates multiple functions such as chest expanders and bench presses. Over the years, the fitness equipment industry has made considerable progress in improving the efficiency, safety, and effectiveness of exercise, especially in the development of fitness equipment designed for specific muscle groups.

[0003] One related technology includes fitness equipment for training the gluteus maximus, comprising a frame with a seat and backrest positioned at an angle. A rotating arm and a barbell arm rotate on the frame, their axes of rotation perpendicular to the plane (sagittal plane) where the angle between the seat and backrest is formed. The rotating arm has a connecting arm for aligning the hamstrings and knees, while the barbell arm has a loading arm for holding the barbell. The rotating arm is connected to the barbell arm via a connecting rod, and both the rotating arm and barbell arm are rotatably connected to the connecting rod. The user aligns the connecting arm with the hamstrings and knees, and pushes the connecting arm around the axis of rotation of the rotating arm by using the hips. Simultaneously, the rotating arm rotates the barbell arm via the connecting rod, achieving vertical or sagittal hip extension. However, this method is relatively ineffective for training the gluteus maximus. Summary of the Invention

These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0038] This specification provides an example of fitness equipment suitable for gluteus maximus training, such as... Figure 1 , Figure 2 as well as Figure 3 As shown, the device includes a support 1; the support 1 is equipped with a seat cushion 2 that contacts the user's buttocks and a backrest 3 that contacts the user's back, and the seat cushion 2 and the backrest 3 are set at an angle, with the plane where the seat cushion 2 and the backrest 3 form the angle being the sagittal plane; rotating arms 4 are rotatably connected to both sides of the support 1 on the sagittal plane, and the distance between the rotating surfaces formed by the rotation directions of the two rotating arms 4 gradually increases from top to bottom; the rotating arms 4 are equipped with a connecting piece 5 that facilitates the user's buttocks to drive in the opposite direction, the connecting piece 5 is used to connect with the user's lower limbs, so that the user can drive the connecting piece 5 by using the buttocks to push the rotating arm 4 to rotate from top to bottom, and the distance between the two connecting pieces 5 gradually increases, thereby realizing the user's hip joint extension and abduction.

[0039] The distance between the plane containing the rotation direction of the rotating arm and the sagittal plane gradually increases from top to bottom, forming a folded angle. Two rotating arms are symmetrically arranged on both sides of the sagittal plane. The connecting piece 5 is located in front of the user; it can be a pedal or a footrest. The initial position is when the connecting piece 5 is at the top, and the final position is when it is at the bottom. The connecting piece 5 extends from above the seat cushion 2 to below it from the initial position to the final position. The distance between the connecting pieces 5 is the horizontal distance between them. The axis of rotation of the rotating arm 4 is not parallel but at an angle. The plane formed by the front-back direction and the up-down direction is parallel to the sagittal plane.

[0040] In one embodiment, a rotating shaft 6 is fixed to the outside of the support 1, and a rotating arm 4 is rotatably connected to the support 1 on the rotating shaft 6. The axial direction of the rotating shaft 6 is such that the fixed point of the rotating shaft 6 on the support 1 is the deflection center, and the rotating shaft 6 is tilted upward in a direction perpendicular to the sagittal plane. The deflection angle is greater than 0 degrees and less than 30 degrees, preferably 5 degrees.

[0041] In one embodiment, the connecting member 5 includes a pedal for stepping; the rotating arm 4 includes a first arm 401, a connecting arm 402, and a second arm 403. The first arm 401 is rotatably connected to a rotating shaft 6. The connecting arm 402 extends from the first arm 401 towards the second arm 403, and the extended end of the connecting arm 402 is connected to the second arm 403. The pedal is mounted on the second arm 403. The user pushes the pedal by applying force with their buttocks and assisting with force with their feet. The pedal is positioned opposite to the second arm 403. The angle between the first arm 401 and the connecting arm 402 is greater than 90 degrees, and the angle between the second arm 403 and the connecting arm 402 is greater than 90 degrees. Preferably, the angles at both points are 120 degrees. The first arm 401, the connecting arm 402, and the second arm 403 are in the same plane.

[0042] In one embodiment, the first arm 401 and the second arm 403 are arranged in parallel, and multiple pedals are provided along the length of the second arm 403. Preferably, there are two pedals, which allows the user to choose which pedal to use based on their habits, comfort, and height, and also provides greater stability when multiple pedals are pressed simultaneously.

[0043] In one embodiment, a support column 8 is provided on the rotating arm 4, and a support pad 9 is provided on the support column 8 to abut against the knee area and / or the area around the knee on the outer side of the leg. The support column 8 is T-shaped, and the vertical rod of the support column 8 is on the same plane as the second arm 403, and the angle between the second arm 403 and the vertical rod is less than 90 degrees, with the angle facing the rear of the fitness equipment. Preferably, it is 75 degrees. The user drives the connecting piece 5 with force through the buttocks, pushing the rotating arm 4 to rotate from top to bottom. The distance between the two connecting pieces 5 gradually increases, which on the one hand further extends and abducts the user's hip joint, and on the other hand, assists in guiding the gluteus maximus muscle training.

[0044] In one embodiment, the distance between the support pads 9 gradually increases from front to back.

[0045] In one embodiment, the fitness equipment further includes a weight-bearing mechanism 10 connected to the rotating arm, the weight-bearing mechanism 10 being used to provide training resistance for pushing the rotating arm 4 from top to bottom and to perform a return motion for pulling the rotating arm 4 from bottom to top.

[0046] The load-bearing mechanism 10 includes a first lever arm 1001, a connecting rod 1002, a second lever arm 1003, and a third lever arm 1004. The first lever arm 1001 is located at the end of the rotating arm 4, and its position at the end of the rotating arm 4 is on the side away from the overlapping member 5 during the rotation of the rotating arm 4. The first lever arm 1001 is movably connected to one end of the connecting rod 1002 via a ball joint. The other end of the connecting rod 1002 is movably connected to the second lever arm 1003 via a ball joint. The second lever arm 1003 is rotatably connected to the bracket 1. The second lever arm 1003 is connected to the third lever arm 1004. The third lever arm 1004 is provided with a loading arm 1005 for mounting a barbell and / or a first loading post 1006 for mounting one end of an elastic band. The bracket 1 is provided with a second loading post. The first loading column 1006 and the second loading column have two limiting rings 11 that restrict the position of the elastic band. The elastic band is located between the limiting rings 11 to prevent it from falling off and to maintain the rotational stability of the rotating arm 4. The third lever arm 1004 is connected to each other by a fixed lever arm 12.

[0047] Regarding the loading arm 1005, which houses the counterweight plate, we have set two loading points at different heights relative to the axis of rotation, allowing for changes or different resistance distributions. This means that the load can be adjusted based on the position of the plate as the machine becomes heavier or lighter within its range of motion.

[0048] In one embodiment, such as Figure 1 , Figure 2 as well as Figure 6As shown, the third lever arms 1004 are connected by a fixed lever arm 12; the fixed lever arm 12 includes a first fixed rod 1201, a second fixed rod 1202, and a sliding connecting rod 1203; one end of the first fixed rod 1201 is fixed to one of the third lever arms 1004, and one end of the second fixed rod 1202 is fixed to another third lever arm 1004; the other ends of the first fixed rod 1201 and the other ends of the second fixed rod 1202 are arranged opposite to each other, and the sliding connecting rod 1203 is arranged along the length of the second fixed rod 1202 in a first sliding connecting groove at the other end of the second fixed rod 1202; the other end of the first fixed rod 1201 is provided with a groove for connecting the sliding connecting rod 1203. 03. A second sliding connecting groove for sliding insertion; the second fixed rod 1202 is provided with a connecting hole communicating with the first sliding connecting groove, and a connecting wrench 1204 fixedly connected to the sliding connecting rod 1203 slides in the connecting hole. The connecting hole communicates with a first locking hole 1205 and a second locking hole 1206; the first locking hole 1205 and the second locking hole 1206 are distributed along the sliding direction of the sliding connecting rod 1203, and the first locking hole 1205 and the second locking hole 1206 are opened in a direction perpendicular to the sliding direction of the sliding connecting rod 1203, so that when the connecting wrench 1204 is turned from the connecting hole into the first locking hole 1205 or the second locking hole 1206, the sliding connecting rod 1203 is locked. When in the position of the first locking hole 1205, the sliding connecting rod 1203 is inserted into the second sliding connecting groove; when in the position of the second locking hole 1206, the sliding connecting rod 1203 is separated from the second sliding connecting groove.

[0049] In one embodiment, the angle between the second bar arm 1003 and the third bar arm 1004 is greater than 120 degrees, and the angle between the second bar arm 1003 and the third bar arm 1004 faces upwards on the fitness equipment.

[0050] In one embodiment, multiple loading arms 1005 are configured along the length direction of the third arm 1004.

[0051] In one embodiment, a support post 13 is provided on the third lever arm 1004, and the support post 13 overlaps the bracket 1 to limit the highest position of the steering arm rotation. For example, the support post 13 overlaps the silicone protective block 14 on the bracket 1.

[0052] In one embodiment, the second arm 1003 and the third arm 1004 are arranged at an angle, and a reinforcing plate 15 is provided at the angle between the second arm 1003 and the third arm 1004. The reinforcing plate 15 forms a concave arc surface on the side facing away from the second arm 1003 and the third arm 1004. The angle between the second arm 403 and the third arm is greater than 120 degrees, preferably 150 degrees. The surface of the reinforcing plate 15 lies in the plane containing the angle between the second arm 403 and the third arm.

[0053] In one embodiment, the fitness equipment further includes a support mechanism 16, which includes a support handle 1601, a first support link 1602, a second support link 1603, a third support link 1604, and a support block 1605.

[0054] The end of the support handle 1601 is rotatably connected to the bracket 1. The support handle 1601 is movably connected to one end of the first support link 1602 via a ball joint. The other end of the first support link 1602 is movably connected to one end of the second support link 1603 via a ball joint. The other end of the second support link 1603 is fixedly connected to one end of the third support link 1604. The other end of the third support link 1604 is fixedly connected to the support block 1605. The support block 1605 is used to support the erected column 13. The third support link 1604 is rotatably connected to the bracket 1. The support block 1605 is located away from the support column 13. The surface where the column 13 is placed abuts against the bracket 1, causing the support handle 1601 to rotate. This, in turn, drives the third support link 1604 to rotate via the first support link 1602 and the second support link 1603. The third support link 1604 then causes the support block 1605 to detach from the bracket 1, ensuring that the support block 1605 does not obstruct the rotation of the third support link 1604 with the column 13 attached. On the other hand, the support handle 1601 rotates back, causing the surface of the support block 1605 facing away from the column 13 to abut against the bracket 1, allowing the column 13 to be stably attached to the support block 1605. For example, the surface of the support block 1605 facing away from the column abuts against the silicone protective block 14 of the bracket 1. The silicone protective blocks 14 are all fixed to the bracket 1 by bolts, and the support block 1605 is provided with a silicone pad that abuts against the column 13.

[0055] In one embodiment, the bracket 1 is provided with a limiting rod 17 to prevent the second top connecting rod 1603 from rotating excessively, and the second top connecting rod 1603 is located above the limiting rod 17.

[0056] In one embodiment, the third top connecting rod 1604 is bent, and the rotation position of the third top connecting rod 1604 is at the bend. The rotation axis 6 of the third top connecting rod 1604 is perpendicular to the bending surface of the third top connecting rod 1604, and the bending angle is 90 degrees. The bending direction of the third top connecting rod faces upwards towards the fitness equipment.

[0057] In one embodiment, the third support rod 1604 and the support block 1605 are arranged corresponding to the erection column 13, and the two third support rods 1604 are connected by a crossbar 18.

Two connecting pieces 19 are also provided on the crossbar 18, and an auxiliary rod 20 parallel to the crossbar 18 is provided between the two connecting pieces 19.

[0058] In one embodiment, such as Figure 1 , Figure 4 as well as Figure 5 As shown, the angle between the backrest 3 and the seat cushion 2 is adjustable, and the backrest 3 is rotatably mounted on the bracket 1. A fixing member 21 is provided at the rear of the backrest 3, and a rotating rod 22 is fixed at the bottom of the fixing member 21. Rotating pieces 23 are formed at both ends of the rotating rod 22, and the rotating pieces 23 are rotatably connected to the rotating shaft 24 of the backrest 3.

[0059] A rotating sleeve 25 is rotatably connected to the outside of the fixing member 21. A support rod 26 slides along the straight line of the rotating sleeve 25 away from the fixing member 21, and the support rod 26 is rotatably connected to the bracket 1. A locking pin 27 is provided on the outside of the rotating sleeve 25 near the support rod 26. The support rod 26 has multiple locking pin holes 41 along the extension direction that interlock with the locking pin 27.

[0060] A rotary wrench 28 is rotatably mounted on the rotary sleeve 25, and the rotating position of the rotary wrench 28 is fixed to the connecting support rod 29 at the end of the rotary connecting lock pin 27.

[0061] The support rod 26 is rotatably connected to the bracket 1 and the fixing member 21 by a first telescopic guide rod 30 that can be extended and retracted.

[0062] In one embodiment, shoulder pads 31 are provided on both sides of the backrest 3 corresponding to the user's shoulders, and the height of the shoulder pads 31 is adjustable along the length of the backrest 3. The shoulder pads 31 at the backrest 3 can increase stability and fix the user in place when the user raises their arms.

[0063] like Figure 4 , Figure 5 as well as Figure 6 As shown, the fixing member 21 includes a fixing sleeve 2101. A sliding rod 2102 is telescopically arranged in the fixing sleeve 2101 along the length direction of the backrest 3. An mounting member 32 is fixed to the end of the sliding rod 2102 that protrudes from the fixing sleeve 2101. Two shoulder pads 31 are mounted on the extension rods of the mounting member 32. The extension rods of the mounting member 32 are connected through the fixing part of the mounting member 32. The mounting member 32 is U-shaped, and the fixing part of the mounting member 32 is fixedly connected to the sliding rod 2102. A locking rod 33 is inserted through the outer side of the fixing sleeve 2101 near the protruding part of the sliding rod 2102. The sliding rod 2102 has multiple locking rod holes 40 along the telescopic direction to facilitate the insertion of the locking rod 33.

[0064] The mounting member 32 is also provided with handles 34 on both sides. The handles 34 are located on the extension rod of the mounting member 32. A U-shaped tie rod 39 is formed on the fixing part of the mounting member 32.

[0065] The fixing rod of the mounting component 32 is rotatably connected to the rotating rod 22 by a second telescopic guide rod 35, which is retractable and guideable. The first telescopic guide rod and the second telescopic guide rod 35 are structures in which a sliding rod slides in the sleeve.

[0066] In one embodiment, auxiliary grips 36 are also provided on both sides of the seat cushion 2 on the support 1. The auxiliary grips 36 are connected to the rotating plate 23.

[0067] In one embodiment, the fitness equipment also includes a safety harness for securing the user's waist. One end of the safety harness is mounted on one side of the seat cushion 2, and the other end of the safety harness and one location on the other side of the seat cushion 2 are provided with a pin 37, while another location is provided with a detachable insertion hole that engages with a buckle. The mating structure of the pin 37 and the insertion hole can refer to the structure of a seatbelt pin 37 in a vehicle. The pin 37 or the insertion hole can be located on a rotating plate 23 on the other side of the seat cushion 2, and the safety harness can be mounted on the rotating plate 23 on one side of the seat cushion 2.

[0068] In one embodiment, the included angle between the rotational surfaces formed by the rotational directions of the two rotating arms 4 is greater than 0 degrees and less than 40 degrees. Preferably, it is 10 degrees.

[0069] In one embodiment, the support 1 is also provided with a placement plate 7 for easy stepping by the user. The rear of the support 1 is also provided with a placement arm 38 for placing barbell plates.

[0070] The user pushes with their feet and provides foot support, as well as through the knee pads. The knee pads are provided because the movement is not 100% straight down, but at an angle. This can be done at the beginning and end; at the beginning, the knee pads are noticeably closer together, but at the end, the horizontal knee pads are noticeably more separated. Although the abduction machine has knee pads and foot support, almost all the force and resistance comes from the side due to the rotational position and direction of the axis relative to the moving arm. The movement in this application combines hip extension (up and down) and hip abduction (pushing outwards), which has a better effect on the gluteus maximus.
