Description

Exercise assistance device

The present invention relates to an exercise assisting device that allows a user to perform other dynamic exercises by moving a footrest.

Conventionally, various types of training machines have been developed for the purpose of maintaining health, and a device mainly composed of a stepping exercise is generally known as a training device for strengthening the body, particularly leg strength.

Further, in Japanese Patent Application Laid-Open No. 2005-58733, an operation in which a user places his / her foot on a footrest and sits on the seat and swings the seat in this state to cause the user to step on the footrest. What gives exercise to a lower limb by making it perform is known. This exercise assisting device is attracting attention in terms of imparting exercise to the lower limbs of a user who has a disease in the knee and cannot bend the knee. However, in conventional exercise equipment that performs stepping, there is an extreme burden on the knees and lower back, which is desired to be used without difficulty for people who have a disease in the knees.

The present invention has been invented in view of the above-described conventional problems, and an object of the present invention is to provide an exercise assisting device capable of adjusting a sinking stroke of a footrest according to a user's physical strength and preference. There is to do.

The exercise assisting device according to the present invention makes it possible to sink the footrest 2 on which a person's foot is placed, and stroke adjusting means 3 for making the stroke L of the footrest 2 sinkable according to the stepping action of the person. It is characterized by comprising.

With such a configuration, a load acts on the user's leg force through the footrest 2 and this acts as a stroke L that sinks. By changing the stroke L of the footrest 2 sinking according to the user by considering the load on the knee of the user by the stroke adjusting means 3, for example, the elderly person can use it with a weak reaction force without difficulty. Can be considered. Furthermore, there is an advantage that leg strength training can be performed in an optimum environment according to each case, such as when there is a disease in the knee or in a healthy person.

The stroke adjusting means 3 is preferably one that makes the vertical movement stroke L of the footrest 2 freely movable up and down. In this case, the footrest 2 moves up and down. Leg strength training by stepping-in exercise can be performed without bending or imposing a heavy burden on the knee joint.

The stroke adjusting means 3 is preferably one that makes the rotation stroke L of the footrest 2 whose tip is rotatable about the base end variable. In this case, for example, when the foot is depressed, If the footrest 2 is rotated so that the toes are lower than the heels, the ankle joint can be dorsiflexed in combination with the stepping movements. If the footrest 2 is rotated so as to be higher, the ankle joint dorsiflexion can be performed in combination with the stepping motion. Further, by adjusting the rotation stroke L of the rotatable footrest 2, there is an advantage that the leg strength training by the sole dorsiflexion of the ankle joint can be performed with the strength adapted to the individual.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

FIG. 1 shows an embodiment of a sitting-type exercise assisting apparatus 1 including a seat 4 on which a person sits and a footrest 2 on which a person's feet are placed.

First, from a mechanical point of view, the exercise assisting device 1 shown in FIG. 1 includes a seat 4 on which a user sits and a rising portion that rises from the rear portion of the base portion 5, which is a seat portion provided with a backrest 20. A main body 1A disposed at the upper end of the base 21, a support 22 rising from the front end of the base portion 5 of the main body 1A, an operation panel 23 disposed at the upper end of the support 22, and left and right upper portions of the support 22

Handles

24, 24, a pair of left and right footrests 2 that can be placed on the upper surface of the base portion 5 so that the left and right feet of the user sitting on the seat 4 can be individually placed, and the rising portion 21. A drive unit (not shown) for swinging and driving the seat 4 is housed in the rising portion 21 of the main body 1A. In addition, the bar 25 arranged on the rising portion 21 of the main body 1A is a bar-shaped one here so that left and right feet can be put on both left and right ends thereof. However, the heel 25 shown in FIG. 1 is in a state in which a user sitting on the seat 4 has retracted his / her foot to a position that does not interfere with the pedestal 2 and when the heel 25 is used, 25 is moved upward. In addition, the support body 22 is attached so as to be rotatable back and forth within a predetermined angle range. Of course, the support body 22 may be set at a predetermined angular position. Further, the left and right footrests 2 are arranged so as to be positioned in front of the rising portion 21 on the upper surface of the base portion 5 and in front of the support 22. The left and right footrests 2 can be moved up and down by a motor (not shown) as a drive source provided in the main body 1A. In addition, in order to accurately perform the alternate stepping motion of the left and right feet, interlocking means for raising the other footrest 2 by lowering one footrest 2 by stepping on the left and right footrest 2 (not shown) Z)).

In the main body 1A having a grounding part on the lower surface of the base part 5, a stroke adjusting means 3 for making the stroke L of the footrest 2 sinkable is provided.

In the example shown in FIG. 2, the footrest 2 is movable up and down, and the vertical movement stroke L in one direction of the footrest 2 can be adjusted with a screw 3 </ b> A that is the stroke adjusting means 3. By changing the protruding direction of the rod-shaped screw 3A in the direction of arrow A, the stroke lower limit position of the footrest 2 can be shifted to the height position P1 or P2 indicated by the broken line in FIG. The vertical movement stroke L [mm] can be lengthened or shortened within the range, and as a result, it can be made longer as indicated by the broken line d with respect to the solid line D shown in FIG.

Accordingly, the user sits on the seat 4 of the exercise assisting device 1 configured as described above, holds the handle 24 provided on the support 22, and the left and right footrests 2 having the stroke adjusting means 3 are placed on the left and right footrests 2. Each one is placed, and an active stepping-in exercise is performed. At this time, in the case of a user who has a disease in the knee and is painful in bending and stretching the knee, the screw 3A constituting the stroke adjusting means 3 is manually operated to reduce the protruding height, thereby allowing the footrest to be lowered. The stroke minimum lower limit position 2 can be made lower than usual, thereby increasing the vertical movement stroke L of the footrest 2 and reducing the load on the knee, which can be used without any problem. In addition, when a healthy person wants to perform an aggressive exercise, the stroke minimum limit position of the footrest 2 can be made higher than usual by increasing the protruding height of the screw 3A, thereby increasing the vertical movement stroke L of the footrest 2. You will be able to do exercises that shorten your thigh strength. In this way, it is possible to perform leg training in an optimum environment according to the user's physical strength and preference.

Further, in this example, since the footrest 2 moves up and down, it is possible to perform leg strength training by stepping motion without bending the knee joint or forcing a heavy burden on the knee joint, and the screw that is the stroke adjusting means 3 There is also an advantage that the stroke lower limit position of the footrest 2 can be easily changed only by changing the protruding height of 3A.

In place of the screw 3A, an airbag (not shown) that is inflated and contracted by supplying and discharging air may be interposed between the footrest 2 and the base. Furthermore, as another example, a mechanism (not shown) for engaging a rack hanging from the footrest 2 side and a rack rising from the base portion side via a pinion may be used. In short, the footrest is movable up and down. Any structure can be used as long as the vertical movement stroke L can be lengthened or shortened within the range of L ′ by adjusting the stroke lower limit position 2.

In the embodiment, the case where the vertical movement stroke L in one direction is changed by the screw 3A is illustrated. However, in addition to the screw 3A, for example, as shown in FIG. You may use the stick | rod 3B. In other words, by placing the tapered surface 6 of the insertion rod 3B on the lower surface side of the footrest 2 and sliding the insertion rod 3B in the direction of the horizontal arrow B, the height of the tapered surface 6 changes, It is good also as a structure which adjusts the stroke minimum minimum position of the mounting base 2 in the range of L 'shown by P1 to P2 of FIG. As another example, as shown in FIG. 5, it is possible to insert the insertion rod 3B into the guide member 7 extending in the vertical direction and adjust the height of the insertion rod 3B and then fix it with the screw 7a. is there.

FIG. 6 shows still another embodiment. The tip 2b of the footrest 2 is rotatable up and down around the base end 2a, and the one-way rotation stroke L of the footrest 2 is variable by the stroke adjusting means 3. An example is shown. The stroke adjusting means 3 of this example is composed of a screw 3A having the same function as that in FIG. 2, and by changing the protruding height of the screw 3A, the broken line d ′ ′ with respect to the solid line D shown in FIG. Thus, the rotation stroke L can be lengthened. Thus, in this example, the rotation stroke L of the footrest 2 can be adjusted, so that the stepping motion that does not impose a burden on the knee can be performed with the strength adapted to the individual, and the distal end 2b of the footrest 2 is centered on the proximal end 2a. When the foot is stepped on, the toe of the foot becomes lower than the heel, so that there is an advantage that the sole dorsiflexion motion of the ankle joint can be effectively performed in combination with the stepping motion. An air bag may be provided instead of the screw 3A, or a rack and pinion mechanism may be provided. As still another modification, as shown in FIGS. 8 and 9, an insertion rod 3B having the same function as that of FIG. 4 or a guide member 7 may be used.

FIG. 10 shows still another embodiment and shows an example in which the vertical movement stroke L of the footrest 2 that can move up and down is adjusted in two directions. In this example, the footrest 2A is moved up and down with respect to the base 2B, and

stroke restricting portions

3a and 3b are provided at both upper and lower ends of the pantograph 3D constituting the stroke adjusting means 3, respectively. Thus, the vertical movement stroke L (L ′, L ″) of the footrest 2A is limited. As a result, it can be adjusted to the broken line d1, d2 in two directions with respect to the solid line D shown in FIG. Thus, as a result of further widening the adjustment range of the vertical movement stroke L of the footrest 2A, it is possible to perform either a stepping exercise with a smaller load or a stepping exercise with a higher load on the legs. .

FIG. 11 shows still another embodiment and shows an example in which the rotation stroke L of the rotatable footrest 2 is adjusted in two directions. In this example, the distal end 2b of the footrest 2 with the base end 2a rotatably supported is inserted between the

stroke limiting portions

3a, 3b provided at the upper and lower ends of the pantograph 3E constituting the stroke adjusting means 3, and the upper and lower The two strokes L (L ′, L ″) of the tip 2b of the footrest 2 are restricted by the

stroke restricting portions

3a, 3b. Thereby, the solid line D shown in FIG. As a result of being able to adjust to the broken lines d1 'and d2' in two directions, respectively, the adjustment range of the rotation stroke L of the footrest 2 is further widened, so that either the rotational motion with a smaller load or the rotational motion with a higher load is performed. Can be performed on the legs.

In the embodiment, the sitting-type exercise assisting device 1 including the seat 4 on which a person sits is illustrated, but the seat 4 is not necessarily required, and can be similarly applied to a standing type that does not include the seat 4. is there.
