The claims defining the invention are as follows:-
1. Kick type training equipment comprising:
a body;
a saddle which is fitted to the body and on which a user is to be seated; and load generating means for, when the user's both legs act thereon, giving a load to both legs, wherein
the load generating means comprises:
a pair of stepping means on which the user's both feet are placed and which are moved in an identical direction by backward alternate kick motion of the user's both legs; and
load means for imparting a load to backward movement of the stepping means and for, upon cancellation of stepping force on the stepping means, automatically returning the stepping means forward.
2. The training equipment according to claim 1, wherein the load generating means further comprises first guide means for guiding the stepping means so that the kick motions of the user's legs are performed while an angle formed by the trunk portion and a femoral region falls within a range of 100° to 220° with the user seated on the saddle.
3. The training equipment according to claim 2, wherein the first guide means guides the stepping means backward substantially along a line.
4. The training equipment according to claim 2, wherein the first guide means guides the stepping means along a circular are.
5. The training equipment according to claim 4, wherein the first guide means comprises a swing arm, and wherein an upper end of the swing arm is pivotally fitted to the saddle or at a substantially saddle level of the body and the stepping means is pivotally fitted to a lower end of the swing arm.
6. The training equipment according to claim 5, wherein a balance weight is coupled to the upper end of the swing arm.
7. The training equipment according to claim 1, wherein the load generating means comprises guide means for guiding the stepping means so that a bending angle of knees is kept substantially constant during a step on the stepping means.
8, The training equipment according to claim 1, further comprising handgrip which is gripped by the user at both hands to stably support the user's trunk portion.
9. The training equipment according to claim 8, wherein the handgrip means comprises a grip 5d to be gripped directly by hand, and arms for supporting the grip in such a way that the grip is adjustable in height position and back-and-forth position.
10. The training equipment according to claim 1, further comprising adjustment means for adjusting the position of the saddle.
11. The training equipment according to claim 1, further comprising belly support means for supporting the user's trunk portion in a forward tilted posture, wherein the belly support means comprises a belly support pad and forward tilt angle adjusting means for adjusting a forward tilt angle of the pad.
12. The training equipment according to claim 1, further comprising an elbow pad for supporting the user's elbow.
13. The training equipment according to claim 1, wherein the saddle comprises a saddle body, a saddle support base for supporting the saddle body upward, and swing means which is placed between the saddle body and the saddle support base and which swings right and left in subordination to right-and-left swinging motion of a waist portion that occurs during the alternate kick motions of the user's legs.
14. The training equipment of claim 1, wherein the saddle comprises a saddle body and a saddle support base for supporting the saddle body upward, the saddle body being formed from a flexible material which can be moved in subordination to the right-and-left swinging motion of the waist portion that occurs during the alternate kick motions of the user's legs.
15. The training equipment according to claim 1, further comprising backrest means for stably supporting back portion of the user seated on the saddle.
16. The training equipment of claim 15, wherein the backrest means comprises a backrest pad and an arm for supporting the backrest pad in such a way that the backrest pad is adjustable in height position.
17. The training equipment of claim 1, wherein the load generating means further comprises control means for making the load during a step on the stepping means substantially constant, and for, upon a cancellation of the pedal stepping force, automatically returning the piston rod to an up position along with the stepping means.
18. The training equipment of claim 17, wherein the control means includes step load increasing and decreasing means for controlling the load during a step on the stepping means so that the load is generally increased and afterwards gradually decreased between initial stage and final stage of the step within a substantially fixed range, where a step initial load and a step final load are given as small ones.
.19. The training equipment of claim 1, wherein the load generating means comprises:
a pair of swing arms which have the stepping means fitted at their lower ends, respectively, and upper ends of which are pivotally fitted to the saddle or at a substantially saddle level of the body; and
a belt which is driven by swinging motion of the swing arms and an end portion of -which is connected to the load means.
20. The training equipment according to claim 19, further comprising plate cam means which is rotated along with rotation of the upper ends of the swing arms, where an end of the belt is fixed to the plate cam means and set along a cam peripheral surface while the other end of the belt is led to the load means by the plate cam means;
wherein the cam peripheral surface of the plate am means has such a configuration as to control the load during a step on the stepping means so that the load is gradually increased and afterwards gradually decreased between initial stage and final stage of the step within a substantially fixed range, where a step initial load and a step final load are given as small ones.
21. The training equipment according to claim 17, wherein the control means further comprises means for adjusting the step lead on the stepping means.
22. The training equipment according to claim 1, wherein the load means is an air cylinder.
23. The training equipment according to claim 22, wherein the stepping means is a pedal, the pedal being fitted to a fore end of the piston rod of the air cylinder.
24. The training equipment according to claim 22, wherein the air cylinder comprises a cylinder body, a piston and a piston rod,
the cylinder body comprising:
an inner cylinder for housing therein the piston and the piston rod so as to allow them to reciprocatingly slide;
an outer cylinder which constitutes a double cylinder in combination with the inner cylinder;
an upper plate which closes upper ends of inner and outer cylinders and through which the piston rod passes;
a bottom plate which seals lower ends of the inner and outer cylinders and which has a freeing port for freeing a bottom portion of an inner cylinder space; and first communicating means for communicating the inner-and-outer cylinder space and the inner cylinder space with each other at their upper portions.
25. The training equipment according to claim 24, wherein the first communicating means is a through hole formed in an upper portion of the inner 26. The training equipment according to claim 24, further comprising pressure adjusting means for adjusting initial pressures of the inner-and-outer cylinder space and the inner cylinder space.
27. The training equipment according to claim 26, wherein the pressure adjusting means comprises:
second communicating means for communicating the inner-and-outer cylinder space with outside;
valve means which connects with the second communicating means;
an air compressor which connects with the valve means; and
pressure control means for controlling the valve means and the air compressor. 28. Kick type training equipment substantially as described herein with reference to Figs. 1 to 4; Fig. 5; or Figs. 6 to 15 of the accompanying drawings.
