Definitions

  • the present invention relates generally to auxiliary exercise equipment which assists a user to stretch user's leg muscles with an aid of external forces.
  • auxiliary exercise equipments which assist a user to stretch user's muscles without effort but with an aid of external forces being applied to the user in order to give an exercise effect.
  • These equipments are known to be configured to apply a force of bending a joint of the user for stretching the muscles associated with the joint (for example, see Japanese Patent Application Laid-Open No. 2007-37850 ).
  • This auxiliary exercise equipment assists a user to contract the muscles of the user's femoral area almost without bending the user's knee. It is possible to strengthen the muscles of the femoral area even if the user has knee pain.
  • a volume of the femoral area's muscles is large, sugar metabolism associated with muscles contraction is efficiently enhanced. Therefore, it's expected to contribute to the improvement of lifestyle diseases such as diabetes.
  • Another auxiliary exercise equipment comprises a foot support platform for supporting the user's foot, and a seat.
  • the equipment assists the user to strain and relax the muscles of the user's femoral area by moving the seat almost without bending the user's knee while supporting the user's buttocks on a contact surface of the seat (for example, see Japanese Patent Application Laid-Open No. 2007-181731 ).
  • This equipment moves a position of the seat and changes a rate of a weight supported by the seat to the user's body weight. This allows a weight acting on the user's leg to change. When the weight acting on the user's leg increases, a mounting surface of the foot support platform descends. Thus, a bending angle of the user's knee is kept at almost a constant angle.
  • the above equipment can reduce a load by such operation. And even if the user is, for example, a diabetic patient and has knee pain, it becomes possible for the user to strengthen the muscles of the femoral area by contracting said muscles almost without bending the user's knee. In addition, because a volume of said muscles is large, it is also expected that sugar metabolism associated with muscles contraction contributes to improvement of lifestyle diseases. Furthermore, the user can exercise passively without effort by using a driving source and moving the seat. Thus, coupled with a light load, it becomes possible for the user to use the above equipment even if the user has a poor exercise capacity or no interest in exercise.
  • a mounting surface of the foot support platform (that is, a top surface) slants downward so that a toe side of the user descends (in a downward direction along a direction from a heel toward a toe), and thereby a load is applied to the toe side larger while a foot joint of the user is plantarflexed.
  • triceps surae muscles a gastronemius muscle and a soleus muscle
  • hamstrings being coordination muscles can also be contracted.
  • muscles around the knee can be contracted simultaneously.
  • the mounting surface of the foot support platform only slants downward along the direction from the heel toward the toe.
  • the prior art has a problem that a load is rarely applied to a heel side of the user according to how the user rides on the seat or an individual difference of a physique, when the seat is moved and the weight acting on the user's leg increases.
  • the load is applied to the heel side larger than the toe side, there is a possibility that too much load may be applied to the knee joint of the user. Therefore, it's expected to prevent too much load from being applied to the knee joint and to strengthen the muscles around the knee.
  • An auxiliary exercise equipment of the present invention comprises a footrest 21 for supporting a foot of a user (M).
  • the footrest 21 is configured so that a part of the footrest 21 relatively retreats from a remaining part of the footrest 21 and thereby is made apart from the foot while the remaining part of the footrest 21 supports the foot.
  • a first configuration when the foot of the user (M) is rested on the footrest 21, the part of the footrest 21 on which the foot is rested is made apart from the foot and the remaining part of the footrest 21 supports the foot.
  • the user (M) has to support almost the user (M)'s full body weight with the remaining part of the footrest 21, and thus a particular muscle can be strengthened.
  • the footrest 21 comprises a plurality of members.
  • the footrest, 21 is configured so that at least one of the plurality of members is bent with respect to a remaining member(s) of the plurality of members and thereby is made apart from the foot of the user (M). In this configuration, the part of the footrest 21 can be relatively moved with respect to the remaining of the footrest by a simple configuration.
  • the plurality of members of the footrest 21 are separately arranged back and forth.
  • the user (M) supports user (M)'s body weight with a back side of the foot and thereby a particular muscle can be strengthened.
  • a back member 21B of the footrest 21 is bent downward, the user (M) supports user (M)'s body weight with a front side of the foot and thereby a particular muscle can be strengthened.
  • the plurality of members of the footrest 21 are a front half 21F and a back half 21B.
  • the footrest 21 is configured so that the front half 21F is bent downward with respect to the back half 21B.
  • mainly an anterior tibial muscle and muscles of a toe can be strengthened.
  • the plurality of members of the footrest 21 are a front half 21F and a back half 21B.
  • the footrest 21 is configured so that the back half 21B is bent downward with respect to the front half 2F.
  • muscles of a toe, a sole and a calf can be strengthened.
  • the plurality of members of the footrest 21 are separately arranged to right and left.
  • the user (M) supports user (M)'s body weight with an inside of the foot of the user (M) and thereby a particular muscle can be strengthened.
  • the user (M) supports the body weight with an outside of the foot and thereby a particular muscle can be strengthened.
  • the plurality of members of the footrest 21 are an inside half and an outside half.
  • the footrest 21 is configured so that the inside half is bent downward with respect to the outside half. In this configuration, when an inside member of the footrest 21 is bent downward, outside muscles of the foot of the user (M) can be strengthened and thereby knock-knee can be corrected.
  • the plurality of members of the footrest 21 are an inside half and an outside half.
  • the footrest 21 is configured so that the outside half is bent downward with respect to the inside half. In this configuration, when an outside member of the footrest 21 is bent downward, inside muscles of the foot of user (M) can be strengthened and thereby bow-legs can be corrected.
  • the footrest, 21 is configured so as to support the foot of the user (M) in the standing position. In this configuration, a full body weight of the user (M) can be applied to the foot of the user (M) and thereby highly-loaded and high-efficient training can be achieved.
  • the auxiliary exercise equipment further comprises a foot support platform 2 for supporting the footrest 21, a seat 51 for supporting buttocks of the user (M) while a sole of the user (M) is rested on a rest-surface 21A of the footrest 21, and a seat driving unit 52 being configured to displace the seat by using a driving source so as to change a weight acting on a leg of the user (M) by the user (M)'s body weight.
  • the foot support platform 2 comprises a supporting base 1a located in a fixed position, and a supporting mechanical part 210 configured to support the footrest 21 with respect to the supporting base 1a while biasing the footrest upward so that the footrest 21 can reciprocate in the vertical direction.
  • the rest-surface 21A of the footrest 21 is formed so as to slant downward along the direction from a heel of the user (M) toward a toe of the user (M), and the supporting mechanical part 210 is configured to relatively move a part back 21B of the footrest 21 larger than a front part 21F of the footrest 21 when the weight acting on the leg increases.
  • the supporting mechanical part 210 is configured to relatively move the back part 21B larger than the front part 21F when the weight acting on the leg increases.
  • a load can be applied to the toe side larger than the heel side, regardless of how the user (M) rides on the seat 51 or an individual difference of a physique.
  • the auxiliary exercise equipment may comprises a detector 61 for detecting a muscle activity of the user (M)'s leg, and a controller 62 being configured to control a movement distance of the footrest 21 moved by the supporting mechanical part 210 according to a result of the muscle activity detected by the detector 61.
  • the movement distance of the footrest 21 is controlled according to the degree of the muscle activity of the user (M)'s leg, and thereby an appropriate load can be applied to the muscles around the knee.
  • the detector 61 may be configured to detect a muscle activity of either hamstrings or triceps surae muscles of a user (M).
  • the hamstrings include a biceps femoris muscle, a semimembranosus muscle and a semitendinosus muscle.
  • the triceps surae muscles include a gastrocnemius muscle and a soleus muscle.
  • the equipment comprises a base 10 located on a fixed position, such as a floor.
  • a handle post (HP) is arranged on the base 10, and comprises a handle (HD), which a user (M) in standing position grips with a hand if needed, at the top.
  • the base 10 is provided with a foot support platform 2 (a left foot support platform 2a and a right foot support platform 2b), a guide section 4 for restricting a travel path of each of the left and right support platforms 2a and 2b, and a drive unit 3 for driving the foot support platform 2.
  • a top surface of the foot support platform 2 is called a rest-surface, and left and right feet of the user (M) are rested on the rest-surface, respectively.
  • the handle (HD) and the handle post (HP) are not indispensable.
  • the base 10 comprises a housing 1 which is composed of a supporting base 1a and an upper plate 1b.

Also, each of the footrest frames 22 is formed with the flange 22b extending around an open face (upper face) over the entire periphery of the main section 22a. In addition, each of the footrest frames 22 has an integrally formed attachment plate 22c at a lower end within the main section 22a.
  • the main section 22a has a longitudinal dimension as well as a width dimension respectively less than those of the openings 11a and 11b, while the flange 22b has such dimensions larger than those of the openings 11a and 11b. Further, a distance between opposed bottoms of the slide grooves 12 is larger than a distance between opposite edges of the flange 22b. Thus, each of the footrest frames 22 is allowed to move within the confines of the slide groove 12 with respect to a width direction as well as a longitudinal direction.
  • Each of footrests 21 is formed into a rectangular plate slightly smaller than an inner periphery of the main section 22a to have such dimensions as to rest a entire foot of the user (M).
