Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, in particular to a multifunctional fitness equipment integrating a high-position pull-down mechanism, a butterfly machine structure, a thigh stretching machine and a sit-up chair, and is characterized in that a multi-stage spring-adjustable adaptive weight is adopted. Background Art

[0002] The four types of fitness equipment on the market today, namely, the high pull-down machine, butterfly machine, thigh extension machine and sit-up chair, are not integrated into one, which increases the equipment cost and occupies a larger area. In addition, many fitness equipment, including the high pull-down machine, butterfly machine and thigh extension machine, usually use weight blocks to provide resistance. The user overcomes the gravity of the weight block to do work, and the force during the exercise is the same. The equipment is easily impacted by inertia and is very noisy, which poses a risk of sports injuries.

[0003] A multifunctional fitness equipment with application number 202322207592.1, which connects the weight part through a pulley and rope system, has the disadvantage that the weight part is designed to be stacked with multiple weight blocks, and the weight of these weight blocks is generally between 2.5-5 kg. When adjusting the weight, it is often necessary to increase or decrease the entire weight block unit, which makes it difficult for the trainer to accurately find the ideal load weight that suits him. For fitness enthusiasts who pursue small span training, this design will cause inconvenience, because they will face the problem of too much weight due to too many weight blocks, or too little weight due to too few weight blocks. Summary of the invention

[0004] In view of the shortcomings of existing fitness equipment such as single function and large floor space, the present invention designs a multifunctional fitness equipment. The fitness equipment integrates a high-position pull-down machine, a butterfly machine, a thigh extension machine and a sit-up chair. The present invention uses a multi-stage spring-adjustable adaptive counterweight instead of a counterweight block to provide the user with the resistance required for exercise, and the lifting platform is pulled up by a pulley and a rope for use.

[0005] The present invention is achieved through the following technical solutions:

[0006] The gravity system includes a housing, a spring, a lifting platform, a slide plate and an adjustment plate, wherein:

[0007] The outer shell of the gravity system is a box, and two symmetrical grooves are arranged on the inner side walls. The spring is fixedly installed on the top of the outer shell. There are four levels of springs in total. A first-level spring is installed in the center of the outer shell, and the second to fourth-level springs are symmetrically distributed on both sides of the first-level spring, with two springs on each side, for a total of 13 springs. The length of the springs at each level is different, and thus the resistance provided is different.

[0008] The lifting platform in the gravity system is provided with 4-level tracks on its side, wherein the first and second level tracks are vertical, and the third and fourth level tracks are horizontal, which correspond to 4-level springs for installing the slide plate and adjusting the required counterweight combination. Two bosses are provided at both ends of the bottom of the lifting platform, which cooperate with the grooves on the side wall of the shell, and the rope is passed through the top of the shell and connected to the bottom ring of the lifting platform to realize the up and down movement of the lifting platform.

[0009] There are 7 slides installed in the gravity system, slide 1 corresponds to the first-stage spring, slides 2 and 3 correspond to the second-stage spring, slides 4 and 5 correspond to the third-stage spring, and slides 6 and 7 correspond to the fourth-stage spring. The tracks of slides 1, 2, and 3 are vertical, and an adjustment plate is needed to select whether the first-stage or second-stage spring is deformed, that is, whether to select the first-stage or second-stage spring for counterweighting. Slides 4 to 7 can move on their respective horizontal tracks, and the knobs on the tops of slides 4 to 7 can be used to select whether the third-stage or fourth-stage spring is deformed, and then the positions of slides 1 to 7 are adjusted to select the counterweight assistance required by the user.

[0010] There are three adjustment plates installed in the gravity system, which are matched with the slide plate 1, the slide plate 2 and the slide plate 3 respectively.

[0011] The lat pull-down machine, butterfly machine and thigh extension machine are connected to the lifting platform in the gravity system through ropes and pulleys. The lat pull-down machine is through the first cableway, the butterfly machine is through the second cableway, and the thigh extension machine is through the third cableway to the gravity system, and then the slide board is adjusted to combine the resistance required by the user to achieve the purpose of counterweight.

[0012] The multifunctional fitness equipment integrating a high-position pull-down machine, a butterfly machine, a thigh extension machine and a sit-up chair is equipped with a total of 15 pulleys, among which pulleys 1 to 6 are fixedly installed on the top bracket, pulleys 9 and 10 are fixedly installed on the column, pulleys 13, 14 and 15 are fixedly installed on the bracket of the base, pulleys 7 and 8 are connected by connecting rods and bolts to form a pulley system 1, and pulleys 11 and 12 are connected by conversion plates and bolts to form a pulley system 2.

[0013] Furthermore, the first cableway is composed of a rope passing around pulley 1, pulley 2, pulley 3, pulley 7, pulley 4, pulley 5 and pulley 6 in sequence; the second cableway is composed of a rope passing around pulley 9 and pulley 10, then passing around pulley 11 in pulley system 2, passing through pulley 12, passing around pulley 13, pulley 8 in pulley system 1, passing through pulley 7, passing around pulley 4, pulley 5, and pulley 6; the third cableway is composed of a rope passing around pulley 15, pulley 14, pulley 12 in pulley system 2, pulley 13, pulley 8 in the pulley system, passing through pulley 7, passing around pulley 4, pulley 5, and pulley 6 in sequence.

[0014] Furthermore, the pulley system 1 is composed of pulley 7 and pulley 8 through a connecting plate and bolts, and the two pulleys rotate in the same plane; the pulley system 2 is composed of pulley 11 and pulley 12 connected by a conversion plate and bolts, and the two pulleys can rotate in different planes, which is more adaptable to various installation positions and space restrictions.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0027] See also Figure 1-Figure 7 A multifunctional adaptive weight-bearing fitness equipment designed in an embodiment of the present invention integrates a high-position pull-down mechanism, a butterfly machine structure, a thigh extension machine and a sit-up chair, and is characterized in that it adopts an adaptive weight-bearing system adjusted by a multi-stage spring, namely, a gravity system c.

[0028] The gravity system described above includes a housing (c40), springs (c50), a lifting platform (c30), a slide plate and an adjustment plate. The characteristic part of the housing is that there is a through hole (c401) on the top and grooves (c402) on both side walls; the springs are divided into four levels, and the length of each level is different. There is one first-level spring (c501), four second-level springs (c502), four third-level springs (c503), and four fourth-level springs (c504). These four levels of springs are all installed on the top of the housing, and their distribution is as follows: Figure 2 It can be seen that the remaining three levels of springs are symmetrically distributed on both sides of the first level spring; the characteristic part of the lifting platform is that there are bosses (c301) at both ends of its bottom, and four levels of tracks are set on the side wall, the first level track (c303), the second level track (c304), the third level track (c305), and the fourth level track (c306); there are a total of 7 slides, and there are 3 styles, slide 1 (c01), slide 2 (c2), slide 3 (c3), slide 4 (c4), slide 5 (c5), slide 6 (c6) and slide 7 (c7). Among them, the first style includes slide 1, which has a through hole (c21) at the center of its top and a groove (c22) at the bottom, as shown in FIG. Figure 4The second style includes a slide plate 2 and a slide plate 3, which differ from the first style in that there is no through hole at the top center; the third style includes a slide plate 4, a slide plate 5, a slide plate 6 and a slide plate 7, and the end surface of the slide plate has a cylindrical knob such as Figure 3 As shown, the bottom is flat, with raised platforms at both ends. Figure 4 As shown, there are three adjustment plates (c8) installed, one each for slide plate 1, slide plate 2 and slide plate 3. The adjustment plates and slide plates are matched as shown in FIG. Figure 7 shown.

[0029] Furthermore, the adjustment plate is embedded in the grooves of the slide plates 1, 2 and 3, and can slide back and forth in the grooves without falling off. The slide plate 1 moves on the first-level track, and the slide plates 2 and 3 move on the second-level track. To select the counterweight resistance of the first-level spring, the slide plate 1 needs to be moved to the upper part of the first-level track and then the adjustment plate needs to be fixed on the lifting platform; the selection of the second-level spring counterweight resistance is achieved through the slide plates 2 and 3, and the slide plates 2 or 3 can be selected separately to achieve half of the counterweight resistance of the second-level spring; the selection of the third-level spring counterweight resistance is achieved through the slide plates 4 and 5, and the slide plates 4 and 5 move on the third-level track, and the knobs at their ends are pulled to move them left and right on the third-level track. When the slide plate 4 moves to the leftmost end and the slide plate 5 moves to the rightmost end, the third-level spring counterweight resistance is selected; the selection of the fourth-level spring counterweight resistance is achieved through the slide plates 6 and 7, and the slide plates 6 and 7 move on the fourth-level track, which is the same as the selection of the third-level spring counterweight resistance.

[0030] Furthermore, the user selects the required weight resistance, and on the multifunctional fitness equipment which integrates a butterfly machine, a high pull-down machine, a thigh extension machine and a sit-up chair, moves the lifting platform up and down to achieve the purpose of exercise. The up and down movement of the lifting platform is achieved by ropes and pulleys. The rope passes through the through hole (c401) at the top of the shell and the central through hole (c011) at the top of the skateboard 1, and is fixed to the grommet (c302) at the bottom of the lifting platform.

[0031] Furthermore, when the user uses the high-position pull-down mechanism of the multifunctional fitness equipment, the user sits on the seat and maintains a correct posture, holds the pull bar (a1) with both hands in a wide or narrow grip, and uses the strength of the back muscles to pull the pull bar down to the chest, such as Figure 1 As shown, the pull rod is connected to the rope, and the rope passes through pulley 1, pulley 2, pulley 3, pulley 7, pulley 4, pulley 5 and pulley 6 in the pulley system 1, that is, the first ropeway, and then connected to the lifting platform. The user pulls the pull rod downward to make the lifting platform move upward, and the spring deforms to provide the counterweight resistance required by the user. The resistance generated is variable. When it is pulled to the lowest point, pause slightly, and then slowly let the pull rod return to the starting position, thus completing one action.

[0032] Furthermore, when the user uses the butterfly mechanism in the multifunctional fitness equipment, he sits on the seat and maintains a correct posture, holds the right handle (a5) with his right hand, holds the left handle (a6) with his left hand, and pushes the handle forward with the strength of his chest to drive the movable arm (a4). At the same time, the rope driven by pushing the right handle passes around the pulley 9 and the rope driven by pushing the left handle passes around the pulley 10 and is connected to the pulley 11 in the pulley system 2. At this time, the pulley 11 is driven to move upward, and the pulley system 2 moves upward as a whole. The pulley system 2 is as shown in FIG. Figure 6 As shown, the pulley 11 and the pulley 12 rotate in different planes through the conversion plate (b103), which better adapts to various installation positions and space restrictions, and then the pulley system 1 is pulled downward by the pulley 13, and then the lifting platform is pulled upward by the pulley 4, the pulley 5 and the pulley 6, and the spring is deformed to provide the counterweight resistance required by the user. When the handle contacts the front end, it pauses slightly, and then slowly returns to the initial position, thus completing one action.

[0033] Furthermore, when the user uses the thigh stretching mechanism in the multifunctional fitness equipment, the user flips the baffle plate (a10) upwards, holds the handle on the baffle plate, and flips the rotating plate so that the arc-shaped side faces upwards. The arc-shaped flip plate is more suitable for bending the thigh joint. The user places the leg joint on the flip plate, and the pressure plate presses on the instep of the user. The front side of the thigh exerts force to drive the pressure plate to move upward, thereby pulling the rope. The rope passes around the pulley 15, the pulley 14, the pulley 12 and the pulley 13 in the pulley system 2 to pull the pulley system 1 downward. The pulley system 1 is as shown in FIG. Figure 5 As shown, pulley 7 and pulley 8 are connected by a connecting plate (b73) and a bolt (b72), and the two pulleys rotate in the same plane. The lifting platform is pulled upward by pulleys 4, 5 and 6, and the spring is deformed to provide the user with the required weight resistance. When the instep lifts the pressure plate until the thigh and calf are almost straight, but the joints are not locked, pause slightly, and then slowly return the handle to the initial position, thus completing one action.

[0034] Furthermore, when using the sit-up chair in the multifunctional fitness equipment, the user should adjust the slope and seat height of the chair according to personal height and body shape to ensure a suitable starting posture. Sit on the chair with your buttocks close to the chair and your back straight but not stiff. Cross your hands in front of your chest or behind your head, but do not use the strength of your arms to help your upper body rise. Slowly tilt your upper body forward and try to use the strength of your abdominal muscles to control the descent and rise of your upper body.
