Definitions

  • the present invention relates to a load generator for effectively producing exercise load by controlling the flow direction and amount of working fluid and a waist exercise appliance for strengthening and rehabilitating the waist using the load generator.
  • the pelvis In general, around the waist region, the pelvis is connected to the vertebrae and two hip joints are connected to the pelvis.
  • Various lumbar muscles are connected to both pelvis and vertebrae, so that the pelvis can conduct movement relative to the vertebrae.
  • U.S. Pat. Nos. 4,902,009 and 5,928,112 disclose conventional appliances that are used to strengthen or rehabilitate the lumber muscles.
  • a user conducts only extension exercises in which the user repeatedly sits up from a position where the upper part of his body is bent while the lower part of his body is firmly held, so the following problems occur due to its structural characteristics.
  • the loading device employed for the conventional appliances is a combination of various weights and accompanied by related accessories, so the entire device occupies an excessive space and is complicated.
  • the conventional appliances are constructed to allow users to conduct only extension exercises for the upper part of the body, so only a part of lumber muscles are strengthened. As a result, the conventional appliances are insufficient for the uniform strengthening and rehabilitating of the entire body.
  • the lower body is tightly held by regions such as the thighs, legs or feet and the pelvis region is moved during the waist exercises, thereby producing deteriorated effects. That is, a method in which the lower body is tightly held by a belt so as to bring the knee into tight contact with a knee holding bar and bring the thigh into tight contact with a seat is to downwardly fix the tight-side of the hip joint. Accordingly, the pelvis-side of the hip joint is nearly free, so the pelvic region can be removed. As a result, the rotational center of waist exercises is removed from the lumbar vertebrae to the hip joint, so the rotational center is not stable, thereby being ineffective for the strengthening of lumbar muscles connecting the pelvis and the vertebrae.
  • US patent no. 5,070,863 discloses a back exercise apparatus with a seat and a foot rest.
  • User can perform exercises under use of a back frame, which can be operated in conjunction with a load generator connected with a gearbox.
  • the foot rest is connected with a knee pad, which can be adjusted relative to the foot rest.
  • the foot rest and the knee pad serve as a lower body holding unit constructed to fix the lower body in front of the seat.
  • US patent no. 4,725,055 discloses a training apparatus, which allows training of a person by a rotation about a vertical axis, which means by turning the upper body around the lumbar vertebrae.
  • the apparatus has a seat on which a person sits.
  • a seat back which bears against the lower back of the person may be moved forward or backward in order to align the natural anatomical axis below the waist of the person with the axis of rotation of the rotation assembly.
  • a lap belt secured into a lap belt buckle holds the person against the seat back and also down against the seat.
  • Two side cushions bear against the pelvis to prevent lateral movement of the pelvis.
  • Two knee pads of a knee pad assembly bear against the inside of the legs between the knees and thighs.
  • Leg straps of the knee pad assembly looped around the outside of the thighs are secured to leg strap buckles on top of the knee pad assembly above the thighs.
  • the knee pads and the leg straps prevent pelvic rotation and thigh movement. Tilting the pelvis or the legs about a horizontal axis cannot be prevented.
  • US 5,549,534 discloses a spine rehabilitation apparatus including a frame having a vertical part and an inclined part.
  • the apparatus comprises a seat and a back rest formed by a convex member connected with the inclined part.
  • the pelvis of a user is only fixed by the seat and the inclined part.
  • US 6,015,372 discloses an apparatus for exercising the abdominal muscles.
  • the apparatus comprises a seat, a movement arm having a resistant pad engageable by the chest of the exerciser and a leg holding unit, for holding the user's legs spread apart.
  • the apparatus does not comprise any foot rests or elements for holding and fixing the pelvis.
  • an object of the present invention is to provide a waist exercise appliance, in which the lumbar muscles can be strengthened using the upper and lower bodies, the lower body and the pelvis are tightly held by the lower body holding unit during waist exercises using the upper body, and the upper and lower portions and the rear portion are distinguished from one another and tightly held in diagonal directions differently from a conventional exercise appliance.
  • Another object of the present invention is to provide a waist exercise appliance, in which while the waist region is exercised using the upper and lower bodies, the degrees of the bending and extension of the knee joint can be adjusted by the adjustment of the height, tilt angle and horizontal position of the foot support, and the quantity and range of the strengthening and rehabilitating of related muscles can be adjusted by the conjunctive movement of the knee holding bar and foot support.
  • a further object of the present invention is to provide a waist exercise appliance, in which the force of the arms is not transmitted to a back frame by a removal prevention unit during extension exercises so as to perform waist exercises only using the upper body, the central axis of the exercise is constructed to coincide with the lumbar vertebrae or hip joint so as to allow the human body and the exercise appliance to harmonize with and be moved in conjunction with each other, the angle range of exercises can be adjusted by an exercise range adjustment unit, and external effects can be excluded from the pure exercise load force by a counter exercise unit.
  • a further object of the present invention is to provide a load generator, which is capable of easily controlling the quantity and direction of load, being simply constructed, being widely used, and being easily installed and utilised.
  • the present invention provides a waist exercise appliance for exercising, strengthening or rehabilitating the waist, in which a chair unit is constructed by assembling all or some of a seat, two legs, a handle and related frames, and exercises are conducted using the back frame or a knee holding bar operated in conjunction with a load generator, further comprising; a lower body holding unit constructed to fix the lower body in front of the chair unit or to be moved along with the lower body, the foot support of the lower body holding unit being constructed to allow its vertical position to be adjusted.
