Description

Technical Field

[0001] This invention belongs to the field of fitness assistive equipment technology, specifically relating to a resistance-assisted multi-strength fitness bench. Background Technology

[0002] With the improvement of living standards, the concept of exercise and health has become deeply rooted in people's hearts. Furthermore, with the accelerated pace of life and work, exercising at home is becoming increasingly popular. Fitness benches, as a type of fitness aid, are often used to assist dumbbells in performing necessary fitness exercises, such as incline dumbbell bench presses, decline dumbbell bench presses, and flat dumbbell flyes. They can also be used for bodyweight exercises like sit-ups. These exercises not only strengthen the arms and abdomen but also improve cardiovascular function, achieving the effect of strengthening the body. However, existing fitness benches cannot directly provide resistance, requiring the use of dumbbells and other auxiliary equipment for lifting exercises. This results in a relatively limited range of motion and a limited number of muscle groups that can be trained. Moreover, dumbbells themselves are bulky, inconvenient to move, and take up a lot of extra space. While frame-type fitness equipment like cable crossover machines can satisfy the need for strength training in various parts of the body in various directions, these machines are large and typically use iron blocks as counterweights, making them cumbersome to use and inconvenient to store when not in use. Summary of the Invention

[0003] The purpose of this invention is to provide a resistance-based multi-strength fitness bench, which solves the problems of the current fitness bench products having relatively limited fitness options and being inconvenient to move and store due to their bulky size.

[0004] The technical solution adopted in this invention is:

[0005] The resistance-equipped multi-strength fitness bench includes a main frame assembly, a seat assembly, a resistance source, omnidirectional pulley locks, and mounting rings. The seat assembly is located above the main frame assembly, and the resistance source is located on the main frame assembly. Mounting rings are installed at several positions on the main frame assembly. Two training ropes extend from the resistance source, and each training rope is connected to a training handle. The omnidirectional pulley locks are used to flexibly mount the training ropes to the mounting rings. The main frame assembly also has display and adjustment components corresponding to the resistance source.

[0006] The invention is further characterized by;

[0007] The main frame assembly includes a front support, a middle support, and a rear support that are hinged together in sequence. The middle support is equipped with the seat cushion of the seat assembly, and the rear support is hinged with the backrest of the seat assembly. An adjustment support assembly for the seat assembly is provided between the backrest and the rear support. The main frame assembly is supported on the ground by the front support and the rear support, and the front support is equipped with a resistance source.

[0008] The rear support includes a rear diagonal brace that is hinged to the middle support at one end, and a rear horizontal bar that is connected to the other end of the rear diagonal brace; a mounting ring is provided on the rear diagonal brace near one end and on the rear horizontal bar near both ends.

[0009] The front support includes a front vertical support rod, from top to bottom, a Roman chair backrest, a leg bending training bar, and a front horizontal bar. The resistance source is located on the front vertical support rod. The front horizontal bar has a pedal and a hanging ring near its two ends, respectively. One end of the leg bending training bar is detachably hinged to the front vertical support rod, and the leg bending training bar has a hanging ring near its middle.

[0010] The Roman chair backrest includes a telescopic vertical bar, a backrest cushion, and a bench press crossbar. The front vertical support bar has a hollow structure, and the telescopic vertical bar can be detachably inserted into the front vertical support bar. Several positioning holes are opened on the side wall of the telescopic vertical bar, and telescopic limit holes are opened on the side wall of the front vertical support bar corresponding to the positioning holes. The telescopic limit holes are equipped with telescopic limit pins. Both ends of the bench press crossbar are equipped with hanging rings.

[0011] The universal pulley lock includes a pulley body, a pulley seat, and a ring lock. The pulley body is rotatably mounted on the pulley seat, and the pulley seat is rotatably connected to the ring lock at a position away from the pulley body. The ring lock has an elastic locking rod at the locking position.

[0012] The resistance source is equipped with a spring-loaded resistance device and a controller. The spring-loaded resistance device includes a rotating shaft and multiple springs that are sequentially sleeved on the rotating shaft along its axial direction. Each spring is also fitted with a storage tray. One end of the training rope is wound around the rotating shaft, and the other end extends outward through a universal pulley installed on the resistance source housing. Each storage tray has a locking switch on its side wall, and the locking switch is electrically connected to the controller.

[0013] The locking switch includes a micro motor, which has an output rod with two smooth rods at both ends and a screw in the middle. A locking block is sleeved on the output rod. A first spring is set between the micro motor and the locking block on the output rod, and a second spring is set on the output rod at a position away from the micro motor from the locking block.

[0014] The resistance source contains a controller and a resistance motor electrically connected to the controller.

[0015] The display adjustment assembly includes an adjustment knob and a display, which are located on the main frame assembly.

[0016] The beneficial effects of this invention are as follows: This invention is a resistance-equipped multi-strength fitness bench with a resistance source that can directly provide fitness resistance, reducing the space occupation and purchase cost of auxiliary equipment such as dumbbells. More importantly, it cleverly utilizes the cooperation of universal pulley locks and hanging rings. Multiple hanging rings are set at different positions on the fitness bench, and the quick-release universal pulley locks are hung on different hanging rings, which can realize the rope pulling exercise in different positions and directions, satisfying people's rope pulling exercises in different parts and directions. The device has a simple structure, is easy to operate, and has good practicality and versatility. Attached Figure Description

[0039] The following detailed description of the resistance-assisted multi-strength fitness bench of the present invention, with reference to the accompanying drawings and specific embodiments, will be provided in further detail.

[0040] The present invention relates to a resistance-assisted multi-strength fitness bench, the main frame assembly of which includes a front support 4, a middle support 5, and a rear support 6. One end of the front support 4 is rotatably hinged to one end of the middle support 5, and the other end of the middle support 5 is rotatably hinged to one end of the rear support 6. A seat cushion 7 of the seat assembly is provided above the middle support 5, and a backrest 8 of the seat assembly is hinged above the rear support 6. The main frame assembly is supported on the ground by the front support 4 and the rear support 6. The adjustable support component between the backrest 8 and the rear support 6 includes a support rod 32 and a limiting groove 33. A fixed frame is provided at the bottom of the backrest 8. One end of the fixed frame is hinged to a rear diagonal support rod 601. The limiting groove 33 is provided at the position of the rear diagonal support rod 601 near the rear horizontal support rod 602. One end of the support rod 32 is movably disposed in the limiting groove 33, and the other end is hinged to the fixed frame.

[0041] The resistance source 1 is fixed on the front support 4. There are multiple hanging rings, two in a group, which are set at different positions on the front support 4 and the rear support 6. The universal pulley lock 3 can be hung on different hanging rings and is detachable. One end of the training rope 2 is connected to the resistance source 1, and the other end passes through the universal pulley lock 3 and is connected to the training handle 9. By cooperating with different hanging rings through the universal pulley lock 3, the training rope 2 can be pulled in different positions and directions.

[0042] Please see Figure 1 The front support 4 of the resistance-assisted multi-strength fitness bench of the present invention includes a front vertical support bar 401, a front horizontal support bar 402 and a Roman chair back 403, and the rear support 6 includes a rear diagonal support bar 601 and a rear horizontal support bar 602.

[0043] Please see Figure 2 The front vertical support rod 401 of the resistance-type comprehensive strength fitness bench of the present invention is provided with a telescopic limiting hole 10, a first hinge seat 11, a second hinge seat 12 and a third hinge seat 13. The telescopic limiting hole 10 is provided with a telescopic limiting pin 101. The first hinge seat 11 is provided with a first unfolding limiting hole 111 and a first folding limiting hole 112, and is provided with a first limiting pin 113. The second hinge seat 12 is provided with a second hinge hole 121 and a second limiting hole 122, and is provided with a second hinge pin 123 and a second limiting pin 124. The third hinge seat 13 is provided with a third hinge hole 131 and a third limiting hole 132.

[0044] Please see Figure 2 The front support 4 of the resistance-type comprehensive strength fitness bench of the present invention is rotatably hinged to one end of the middle support 5 through the first hinge seat 11. When the fitness bench is unfolded, the first limiting pin 113 is inserted into the first unfolding limiting hole 111 for limiting and fixing. When the fitness bench is folded, the first limiting pin 113 is inserted into the first folding limiting hole 112 for limiting and fixing. The pin method can ensure the structural stability of the fitness bench in the unfolded or folded state. It is also simple and convenient to operate and quite practical.

[0045] Please see Figure 2 The resistance-assisted multi-strength fitness bench of the present invention also includes a leg-bending training bar 17. The leg-bending training bar 17 is detachably hinged to the second hinge seat 12 and the third hinge seat 13. It is hinged by inserting the second hinge pin 123 into the second hinge hole 121 or the third hinge hole 131, and limited by inserting the second limiting pin 124 into the second limiting hole 122 or the third limiting hole 132. This allows the leg-bending training bar 17 to rotate around the second hinge pin 123, while ensuring that the leg-bending training bar 17 has a certain initial tilt angle, which is convenient for the operator to use.

[0046] Please see Figure 1 and Figure 2The Roman chair back 403 of the resistance-assisted multi-strength fitness bench of the present invention includes a telescopic vertical rod 19, a backrest 20, and a bench press horizontal bar 21. The front vertical support rod 401 has a hollow structure. The telescopic vertical rod 19 of the Roman chair back 403 is detachably installed in the hollow structure. The telescopic vertical rod has multiple positioning holes, and the front vertical support rod 401 has a telescopic limiting hole 10. The height of the Roman chair back 403 can be adjusted and limited by inserting a telescopic limiting pin 101 into the telescopic limiting hole 10 and the positioning hole, thereby meeting the height adjustment needs of the Roman chair back 403 for different heights or different fitness movements.

[0047] Please see Figure 2 The rear inclined support rod 601 of the resistance-type comprehensive strength fitness bench of the present invention is provided with a fourth hinge seat 14 at one end. The fourth hinge seat 14 is rotatably hinged to the other end of the middle support 5. The middle support 5 is provided with a fourth unfolding limiting hole 141 and a fourth folding limiting hole 142 at one end near the fourth hinge seat 14, and is also provided with a fourth limiting pin 143. When the fitness bench needs to be unfolded, the fourth limiting pin 143 is inserted into the fourth unfolding limiting hole 141 for limiting and fixing. When the fitness bench needs to be folded, the fourth limiting pin 143 is inserted into the fourth folding limiting hole 142 for limiting and fixing. The pin can ensure the structural stability of the fitness bench in the unfolded or folded state, and the operation is simple and convenient.

[0048] Please see Figure 3 The present invention relates to the arrangement of the hanging rings in the resistance-assisted comprehensive strength training bench. The front horizontal bar 402 is provided with a pedal 15 and a first hanging ring 16 near both ends, with the first hanging ring 16 on the outside of the pedal 15. The leg bending training bar 17 is provided with a second hanging ring 18. The two ends of the bench press bar 21 are provided with a third hanging ring 22. The rear inclined support bar 601 is provided with a fourth hanging ring 23 near the fourth hinge seat 14. The two ends of the rear horizontal bar 602 are provided with a fifth hanging ring 24.

[0049] Please see Figure 4 , Figure 5 and Figure 6 The universal pulley lock 3 of the resistance-type multi-strength fitness bench of the present invention includes a pulley body 301, a pulley seat 302 and an annular lock 303. The pulley body 301 is rotatably mounted on the pulley seat 302, and the pulley seat 302 is rotatably connected to the annular lock 303. As an embodiment, the annular lock 303 can refer to the design of a carabiner used in daily life, and is provided with an opening. An elastic locking rod 304 is provided at the position of the opening.

[0050] The resistance source 1 of the resistance-assisted multi-strength fitness bench of the present invention can be equipped with a motor to provide resistance. When rope pulling exercise is required, the operator pulls the training rope 2, which gives the motor shaft a clockwise (or counterclockwise) rotational force. The power supply drives the motor to give the shaft a counterclockwise (or clockwise) force, thus creating a force resistance with the operator, allowing the operator to perform rope pulling exercise. The magnitude of the resistance can be controlled by the controller 34 to control the voltage and / or current of the power supply.

[0051] The resistance source 1 in the resistance-assisted multi-strength fitness bench of the present invention can also be provided externally by a spring-loaded device;

[0052] As one implementation method for generating resistance in resistance source 1, when using a spring-loaded device to provide resistance externally, please refer to... Figure 7 The spring mechanism includes a rotating shaft 25, and multiple sets of springs 26 and storage trays 27 arranged side by side around the rotating shaft 25. The inner end of the spring 26 is fixedly connected to the rotating shaft 25, and the outer end of the spring 26 is fixedly connected to the inner wall of the storage tray 27. The outer circumference of the storage tray 27 is evenly provided with multiple teeth. A locking switch 29 is provided for each storage tray 27. The locking switch 29 is located inside the housing of the resistance source 1. One end of the training rope 2 is wound around the rotating shaft 25, and the other end extends outward through the universal pulley 28 on the housing of the resistance source 1 to provide rope resistance.

[0053] Please see Figure 8 , Figure 9 , Figure 10 and Figure 11 Each locking switch 29 includes a micro motor 291. The micro motor 291 is provided with an output rod with two smooth rods at both ends and a screw in the middle. A locking block 292 is sleeved on the output rod. The locking block 292 is provided with a screw hole. A first spring 293 is provided between the micro motor 291 and the locking block 292. A second spring 294 is provided on the output rod at a position away from the micro motor 291 from the locking block 292.

[0054] The operating principle of the locking switch 29 in the resistance-assisted multi-strength fitness bench of this invention is as follows:

[0055] It is pre-set that when the micro motor 291 drives the output rod to rotate clockwise, the screw can push the locking block 292 to move to the left; when the micro motor 291 drives the output rod to rotate counterclockwise, the screw can push the locking block 292 to move to the right.

[0056] Please see Figure 8 and Figure 9When the screw hole of locking block 292 is on the left side of the output rod, if the micro motor 291 drives the output rod to continue rotating clockwise, since the screw hole of locking block 292 is on the left side of the output rod, it loses the leftward thrust generated by the screw rotation. At this time, locking block 292 cannot continue to move to the left, and the first spring 293 on the left is in a compressed state, thereby pushing the right end of the screw hole of locking block 292 to abut against the left end of the screw of the output rod, and locking block 292 remains in its current position. If the micro motor 291 changes its rotation direction (from clockwise to counterclockwise), under the thrust of the first spring 293 on the left, the screw hole of locking block 292 will engage with the screw of the output rod, and locking block 292 will move to the right under the rightward thrust generated by the screw rotation until the screw hole of locking block 292 disengages from the screw of the output rod, and the screw hole of locking block 292 is on the right side of the output rod.

[0057] Please see Figure 10 and Figure 11 At this point, the screw hole of locking block 292 is on the right side of the output rod, losing the rightward thrust generated by the rotation of the screw. Locking block 292 cannot move further to the right, and the second spring 294 on the right is compressed, thus pushing the left end of the screw hole of locking block 292 to abut against the right end of the screw of the output rod, and locking block 292 remains in its current position. If the micro motor 291 changes direction again (from counterclockwise to clockwise), under the thrust of the second spring 294 on the right, the screw hole of locking block 292 will engage with the screw of the output rod again, and the locking block will move to the left under the leftward thrust generated by the rotation of the screw until the screw hole of locking block 292 disengages from the screw of the output rod again, and the screw hole of locking block 292 returns to the left side of the output rod.

[0058] Therefore, by simply controlling the rotation direction of the micro motor 291, the moving direction and stopping position of the locking block 292 can be controlled.

[0059] The principle behind the resistance adjustment mechanism of the spring-loaded device in the resistance-bearing multi-strength fitness bench of this invention is as follows:

[0060] When the micro motor 291 controls the locking block 292 to move to the left position, the locking block 292 engages with the teeth of the outer ring of the storage tray 27, thereby restricting the rotation of the storage tray 27. Because the outer ring end of the spring 26 is fixed to the inner wall of the storage tray 27 and the inner ring end is fixed to the rotating shaft 25, when the external force pulls the training rope 2, the training rope 2 pulls the rotating shaft 25 to rotate, thereby causing the spring 26 to coil and deform. During this process, in order to resist the coiling deformation, the spring 26 will apply a reverse torque to the rotating shaft 25, ultimately forming a resistance against the tension of the training rope 2.

[0061] When the micro motor 291 controls the locking block 292 to move to the right position, the locking block 292 separates from the meshing teeth of the outer ring of the storage tray 27. At this time, the storage tray 27 can rotate because the outer ring end of the spring 26 is fixed to the inner wall of the storage tray 27, and the inner ring end is fixed to the rotating shaft 25. When the external force pulls the training rope 2, the training rope 2 pulls the rotating shaft 25 to rotate, which is transmitted to the storage tray 27 through the spring 26, thereby driving the storage tray 27 to rotate. Therefore, the spring 26 will not be coiled or deformed, that is, it will not apply a reverse torque to the rotating shaft 25.

[0062] Therefore, by controlling the rotation direction of the micro motor 291 through the controller 34, the stopping position of the locking block 292 can be controlled, and finally the spring spring 26 can be controlled to coil and deform to generate reverse resistance, thereby adjusting the resistance of the resistance source 1.

[0063] In this embodiment, five sets of spring-loaded springs 26, storage trays 27, and locking switches 29 can be pre-configured. The spring force of the spring-loaded springs 26 is one unit, two units, four units, eight units, and sixteen units, respectively. Then, the controller 34 controls the engagement or disengagement of the locking switches 29 and the outer ring teeth of the storage trays 27 in each set. This allows for the combined output of spring force in one-unit increments, ranging from zero to thirty-one units. It should be noted that the above-mentioned pre-configured number of sets and spring force relationship is only one scenario and does not constitute a limitation on other pre-configurations or scenarios.

[0064] Please see Figure 3 In this embodiment, the front bracket 4 is also provided with an adjustment knob 30 and a display 31, which are electrically connected to the resistance source 1.

[0065] Please see Figure 15 In this embodiment, a support rod 32 is rotatably hinged to the lower part of the backrest 8, and a serrated limiting groove 33 is provided on the rear bracket 6. The end of the support rod 32 away from the backrest 8 cooperates with the limiting groove 33. At this time, the angle of the backrest 8 can be adjusted simply by adjusting the support rod 32 to fall into different grooves of the limiting groove 33.

[0066] In this embodiment, the resistance source 1 can be directly powered by an external power source or by a built-in rechargeable battery. When no external power source is connected, it is powered by the built-in rechargeable battery. When an external power source is connected, it powers the rechargeable battery while simultaneously charging it.

[0067] In summary, the resistance-assisted multi-strength fitness bench of the present invention has many different application scenarios, some of which are listed below.

[0068] Scenario 1: The universal pulley lock 3 is attached to the mounting ring 22;

[0069] Please see Figure 12 In this scenario, the universal pulley lock 3 is attached to the mounting ring 22, turning the training rope 2 to a relatively horizontal position. The user can sit facing the training rope and pull the rope, exercising the arm, shoulder, and back muscles by straight pulling or chest expansion. The user can also sit with their back to the training rope and pull the rope, increasing the exercise of the chest muscles by straight pushing or parallel rope chest clamping.

[0070] Scenario 2: The universal pulley lock 3 is attached to the mounting ring 24;

[0071] Please see Figure 13 In this scenario, the universal pulley lock 3 is attached to the mounting ring 24, which turns the training rope 2 to a relatively vertical direction. The user can perform rope pulling exercises in a supine position. By pushing upwards or supine flyes, the user can exercise the muscle groups of the arms and chest. The user can also perform rope pulling exercises in a prone position. By prone flyes, the user can exercise the muscle groups of the arms and back.

[0072] Scenario 3: The universal pulley lock 3 is attached to the mounting ring 24;

[0073] Please see Figure 14 and Figure 15 In this scenario, the universal pulley lock 3 is attached to the mounting ring 24, and the backrest 8 is adjusted to a certain angle. The training rope 2 is then switched to a relatively vertical direction. The user can lean against the backrest 8 and exercise the muscle groups of the arms, chest, and shoulders by pushing at an angle and lifting upwards.

[0074] Scenario 4: The universal pulley lock 3 is attached to the mounting ring 23;

[0075] Please see Figure 16 In this scenario, the universal pulley lock 3 is attached to the mounting ring 23, which turns the training rope 2 to a relatively vertical direction. The user can perform one-handed rope pulling exercise by kneeling on the fitness bench, achieving a training similar to dumbbell bent-over bicep, which can exercise muscle groups such as arms, back and shoulders.

[0076] Scenario 5: The universal pulley lock 3 is mounted on the mounting ring 16;

[0077] Please see Figure 17In this scenario, the universal pulley lock 3 is attached to the mounting ring 16, turning the training rope 2 to a relatively vertical direction. At the same time, the Roman chair back 403 is removed to leave more room for movement. At this time, the user can stand on the pedal 15 to perform rope pulling exercises. By pushing, lifting, raising, or bending the arms, the user can exercise the muscle groups of the arms and shoulders. Alternatively, the training handle 9 can be replaced with a straight bar to perform training movements such as deadlifts and squats, which can exercise the muscle groups of the legs and waist.

[0078] Scene 6: Training rope 2 is attached to the mounting ring 18;

[0079] Please see Figure 18 In this scenario, the training rope 2 is directly attached to the mounting ring 18, connecting the training rope 2 to the leg bending training bar 17. The leg bending training bar 17 is inserted into the second hinge hole 121 via the second hinge pin 123 and rotated to hinge onto the second hinge seat 12. Then, the second limit pin 124 is inserted into the second limit hole 122 to limit the leg bending training bar 17, ensuring that the leg bending training bar 17 has a certain initial tilt angle. The user can sit on the fitness bench with the insteps of both feet placed under the leg bending training bar 17 to achieve seated leg flexion and extension training, which can exercise the leg muscles, especially the front thigh muscles.

[0080] Scene 7: Training rope 2 is attached to the mounting ring 18;

[0081] Please see Figure 19 In this scenario, the training rope 2 is directly attached to the mounting ring 18, connecting the training rope 2 to the leg bending training bar 17. The leg bending training bar 17 is inserted into the third hinge hole 131 through the second hinge pin 123 and rotated to hinge onto the third hinge seat 13. Then, the second limit pin 124 is inserted into the third limit hole 132 to limit the leg bending training bar 17, ensuring that the leg bending training bar 17 has a certain initial tilt angle. The user lies prone on the fitness bench with the heels of both feet placed under the leg bending training bar 17 to perform prone leg bending and extension training, which can exercise the leg muscles, especially the hamstring muscles.

[0082] The above are just a few examples of the application scenarios of the resistance-assisted multi-strength fitness bench of this invention. They do not represent a limitation on the application scenarios. In actual use, various changes can be made according to the user's needs. Users can also freely conceive and implement these changes. For example, the training handles can be replaced with other auxiliary equipment to achieve more and richer training movements, thereby satisfying the user's needs for exercising different parts of their body.

[0083] Please see Figure 2 , Figure 20 and Figure 21The resistance-assisted multi-strength fitness bench of the present invention can also be folded. When the fitness bench is folded, the first limiting pin 113 is inserted into the first folding limiting hole 112 for limiting and fixing, and the fourth limiting pin 143 is inserted into the fourth folding limiting hole 142 for limiting and fixing. The pins can ensure the structural stability of the fitness bench after folding, making the operation convenient and simple, and reducing the space occupied by the fitness to a certain extent, making it convenient for home use.

[0084] This invention relates to a resistance-based multi-strength fitness bench. In addition to the functions and uses of a traditional fitness bench, it can directly provide resistance, reducing the space occupation and purchase cost of auxiliary equipment such as dumbbells. More importantly, it cleverly utilizes the combination of universal pulley locks and hanging rings. Multiple hanging rings are set at different positions on the fitness bench, and the quick-release universal pulley locks are hung on different hanging rings, which can realize the rope pulling exercise in different positions and directions. It meets the needs of people to pull ropes to exercise different parts of their bodies in different directions. The structure is simple, easy to operate, and has strong practicality and versatility.
