detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 1 and FIG. 2, the exercise machine (also called the spine and its muscle fitness machine) mainly comprises two parts, and the first part is used for supporting and arranging the body part of the person, that is, the bench 16 or the long board 18, The second part is the resistance and recovery device 14.

The body part device of the person to be placed includes a main bracket, a bench 16 disposed on the main bracket, a long board 18 hinged to one end of the bench 16, and a double hinge 20 connecting the bench 16 and the long board 18. The long plate 18 is in contact with a resisting and returning device that, under the active action of the exerciser's body or leg, causes the resisting and returning device 14 to generate a passive force, and the long plate 18 acts in these roles. The force swings up and down around its hinge end.

The main function of the fitness device is to fix and support the exercise machine, and keep the bench 16 in a balanced state. The main support can be composed of a bracket or a hollow structure surrounded by a flat plate. In the preferred embodiment, as shown in FIG. 1, the main bracket includes a first bracket 22, a second bracket 23, and a fourth bracket 50. When the fitness device is in use, the fourth bracket 50 is placed on the ground, and the first bracket 22 and the top of the second bracket 23 are fixed to the bottom ends of the bench 16 to support the bench 16, the first bracket 22, The bottom ends of the second brackets 23 are respectively fixed to both ends of the fourth bracket 50.

In this embodiment, the bottom of one end of the bench 16 and the bottom of one end of the longboard 18 are movably connected by a double hinge 20 (as shown in FIGS. 7 and 8-1), and the fixed blades 20C and 20D of the double hinge 20 are provided. They are respectively fixedly connected to the bottom of the second end of the bench 16 and the bottom of the first end of the long plate 18. The second end of the long plate 18 is a free end and is rotatable around the first end. In addition to the double hinge 20 in this embodiment, it is also possible to use a commonly used hinge structure such as an articulated shaft, and is not limited to the illustrated double hinge structure with fixed blades.

As shown in FIG. 1 and FIG. 7, the extension ring 20E at the two ends of the double hinge 20 is respectively provided with an extension hole 20F. The first bracket 22 is provided with two rings 20B, and the ring 20B is positioned inside the two extension holes 20F. When the iron 20A passes through the two extending holes 20F and the ring 20B, the double hinge 20 is fixed on the first bracket 22, and the exercise machine is in a usable state; when the iron 20A is pulled out, the long plate 18 can be rotated. To the top of the bench 16, it overlaps with the bench 16, and the exercise machine is in a stowed state and is not used.

In order to increase the comfort of use, in order to prevent the user's body from being caught by the gap between the bench 16 and the long board 18, a mat 24 is placed over the joint of the bench 16 and the long board 18, as shown in FIG.

In a specific embodiment, the resisting and returning device 14 is fixed to the main bracket, and includes a force transmitting device and a force balancing device. The force transmitting device includes a curved rod 42 fixed to the rotating shaft 41 at one end. Up, and synchronously rotating with the rotary shaft 41 relative to the main bracket, the other end of the curved rod 42 is slidably coupled with the bottom of the long plate 18; the force balance device includes a weight rod 46 and one end fixed to the weight rod 46 The weight 46C, the other end of the weight bar 46 is fixed to the rotary shaft 41 and rotates in synchronization therewith.

Therefore, the second part, the resistance and recovery device 14, can be said to be composed of the rotary shaft 41, the third bracket 40, the curved rod 42, the weight rod 46, the starting angle adjusting device (the first sector plate 44 in this embodiment), and The maximum angle adjusting device (the second sector plate 48 in this embodiment) is composed of components.

A third bracket 40 is disposed beside the main bracket. In the specific embodiment of FIG. 4, the third bracket 40 is further divided into a vertical rod 40A and a vertical rod 40B, and the rotary shaft 41 is disposed at the top end of the vertical rod 40A and the vertical rod 40B, and It is perpendicular to the vertical rod 40A and the vertical rod 40B to ensure the support force of the rotary shaft 41 and the smoothness of the rotation. The rotary shaft 41 is disposed on the third bracket 40, and one end of the curved rod 42 is indirectly fixed to the rotary shaft 41, and rotates synchronously with the rotary shaft 41, and the other end, that is, the free end is slidably connected to the bottom of the long plate 18; The weight bar 46 is directly fixed to the rotary shaft 41 and rotates in synchronization with 41. The other end of the weight bar 46 can be placed with a weight 46C, such as a discus.

As shown in Fig. 3, in one of the methods of use of this embodiment, when the user lies flat on the bench 16, the legs are placed on the long board 18 (Fig. 14). When the leg presses the long plate 18 downward, the bottom end of the long plate 18 bends the free end of the rod 42, the curved rod 42 drives the rotary shaft 41 to rotate; and the rotation of the rotary shaft 41 drives the fixed weight rod 46 to rotate. The weight 46C (the present embodiment is a discus) at the other end of the weight bar 46 is lifted to a certain height; under the weight of the weight 46C, the weight bar 46 exerts a certain resistance to the rotary shaft 41. When the long board 18 is lowered to the downward tilting state, the angle of intersection of the bench 16 and the long board 18 is greater than 180 degrees, which serves two purposes: first, since the long board 18 is inclined, the person's leg or body is on the board. The upper side is also tilted downwards, when the human spine is stretched and the intervertebral disc is enlarged. The second function is that the resistance and recovery device provides a resistance to the long plate 18 at this time, and this resistance makes the human body have to exert force to resist it. At this time, the muscles and leg muscles around the human spine are exercised. When the leg or body stops moving down and the person's leg or body is consciously lifted up, under the action of the weight 46C, the longboard 18 will automatically return to the initial or near initial position; at this time, the longboard 18 rises. At this time, it also has two functions: first, the human spine returns from the stretched state to the normal (ie, compressed) state. Second, the weight 46C drives the rotary shaft 41 to rotate under the action of gravity, and the rotary shaft 41 drives the rotary shaft 41 again. The curved rod 42 rotates, and the curved rod 42 gives a restoring force to the long plate 18 at this time. This restoring force can help the person's leg or body to lift up, thereby achieving the muscles and leg muscles around the spine, and avoiding the damage of the lumbar spine. . This reciprocating effect can achieve the effect of exercise.

The resistance and recovery device is slidably connected to the bottom of the long plate 18, mainly when the long cymbal 18 is rotated downward, the friction at the contact end of the resistance and recovery device can be reduced to ensure the smoothness of the exercise and the exercise machine. The service life; its structure can adopt common sliding or rolling connection structures such as rollers and balls.

In order to adjust the starting angle of the long plate 18, the position adjustment means can be used to define the starting position of the long plate 18. Therefore, the resistance and recovery device further includes a starting angle adjusting device fixed to the rotating shaft 41, and at least two starting angle positioning devices are disposed thereon; the curved rod 42 passes The different starting angle positioning devices are fixed at different positions on the starting angle adjusting device, and the other end of the curved rod 42 is slidably coupled to the long plate 18. The starting angle positioning device may be a common position adjusting device of a common positioning card slot, a positioning cam, a positioning hole and a positioning pin.

The starting point positioning hole is provided with a connecting hole, and the curved rod 42 is fixed in the starting angle positioning hole through the connecting hole through the positioning pin 42E. The first sector plate 44 is fixed to the rotary shaft 41 and is rotatable about the fixed point with the rotary shaft 41. When the connecting holes on the curved rod 42 are fixed in different starting angle positioning holes, the curved rod 42 is located at different positions of the first sector flat plate 44, due to the long plate 18, the curved rod 42 and the rotary shaft 41, and the weight 46C For the connection and balancing, the long plates 18 will be at different starting angles.

As shown in FIG. 2, FIG. 3 and FIG. 4, the two ends of the curved rod 42 are perpendicular to each other, but not in the same plane. One end of the curved rod 42 is sleeved on the rotary shaft 41 and can be rotated on 41, and the curved rod 42 is rotated. The fixing pin 42E is fixedly connected with the starting angle positioning adjusting device (ie, the first sector plate 44), so that the curved rod 42 can be rotated simultaneously with the rotating shaft 41, and the other end of the curved rod 42 is a free end, and the sliding device is mounted thereon. , can slide at the bottom of the long board 18.

The function of the sliding device 42A is mainly to reduce the friction at the contact end of the curved rod 42 during the contact between the long plate 18 and the curved rod 42, so as to ensure the smooth and smooth movement of the long plate 18 and the service life of the exercise device, and the structure can be adopted. A commonly used sliding or rolling connection structure such as a roller or a ball is selected as a sliding device in this embodiment. The first rod 42D is provided with the connecting hole, and the positioning pin 42E is fixed in the starting angle positioning hole through the connecting hole. When the positioning pin 42E is fixed into the different starting angle positioning holes through the connecting holes of the first rod 42D, the sliding device 42A causes the long plates 18 to be at different starting angles.

The resistance and recovery device further includes a maximum drop angle adjustment device fixed to the main bracket, the maximum drop angle adjustment device being provided with a maximum drop angle positioning device that can intersect the weight rod 46, When the weight bar 46 touches the maximum drop angle positioning device during rotation, the rotation is stopped and the rotary shaft 41 is stopped to stop the rotation, and the long plate 18 reaches the maximum depression angle.

In this embodiment, as shown in FIGS. 2 to 3, the resisting and returning device includes a weight bar 46 and a weight 46C fixed to one end of the weight bar 46, and the other end of the weight bar 46 is fixed to the The rotary shaft 41 is rotated and rotated in synchronization therewith. The maximum drop angle position adjusting device is provided with a maximum drop angle positioning device that can prevent the weight bar 46 from continuing to swing. When the weight bar 46 touches the maximum drop angle positioning device during rotation, the rotation stops and drives The rotary shaft 41 stops rotating, and the curved lever 42 fixed to the rotary shaft 41 stops rotating and abuts against the long plate 18, so that the long plate 18 cannot continue to rotate downward, so that the long plate 18 reaches the maximum depression angle. This structure is advantageous for preventing excessive bending of the spine and causing spinal damage.

In this embodiment, the maximum falling angle adjusting device is a second fan-shaped flat plate 48, and the maximum falling angle positioning device is a positioning rod 48A, and the second fan-shaped flat plate 48 is provided with a maximum falling angle positioning uniformly distributed around the center of the circle. The hole, the positioning rod 48A is inserted into the plane of the second sector plate 48 through the maximum drop angle positioning hole (shown in FIG. 4-2). When the positioning rod 48A is inserted in the different maximum drop angle positioning holes, the weight rod 46 can be blocked at different heights, so that the long plate 18 reaches the maximum depression angle. The structure of the maximum drop angle adjusting device and the maximum drop angle positioning device may be set to be various, as long as the maximum swing angle of the control weight bar 46 or the weight 46C or the rotation angle of the rotary shaft 41 can be controlled. The maximum downforce angle of the control long plate 18 is reached.

The weight bar 46 includes a fourth rod 46A and a fifth rod 46B. The first end of the fourth rod 46A is vertically fixed on the rotary shaft 41 and rotates synchronously with the rotary shaft 41. The middle portion of the fifth rod 46B is vertically fixedly connected, and the fifth rod 46B is parallel to the rotary shaft 41; the weight 46C is placed on the fifth rod 46B and swings in synchronization therewith.

A spring piece 46D may be disposed at a position where the fourth rod 46A is in contact with the positioning rod 48A to buffer the collision of the two rods. In order to make the positioning rod 48A not easily loose when inserted into the through hole 48K, a small spring piece (see FIG. 4-2 in this embodiment) or a small marble may be disposed on the positioning rod 48A, or may be at the end of the positioning rod 48A. Set a small through hole and insert a pin at the small through hole.

The weight 46C can be various weights, such as iron balls, iron blocks, etc. In the present embodiment, the iron cake is selected as the weight 46C, and the iron cake is placed on the fifth rod 46B. The two ends of the fifth rod 46B are respectively provided with through holes. After the iron cake is placed and pushed into the fifth rod 46B, the bolt 46B-1 can be inserted into the through hole to prevent the disc from sliding off the fifth rod 46B.

In order to define the lowest point position of the discus during the movement, while avoiding the collision of the discus with the ground during the movement, the third bracket 40 is further provided with a vertical rod 40G, which is in the same shape as the fourth rod 46A. The plane is located at the lower portion of the fourth rod 46A. When the fourth rod 46A is swung to a certain extent, the top end of the vertical rod 40G will abut against the fourth rod 46A to prevent it from continuing the hem.
