Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a body training device for training a body by alternately moving left and right legs on a circulating endless belt.

[Prior art]

In the past, most of this type of body training apparatus was of a running machine type in which an endless belt was circulated while running while running.

[Problems to be solved by the device]

However, this is simply running, and although the legs can be lightly exercised, the spine, abdominal muscles, arms, shoulders, etc. cannot be exercised. An object of the present invention is to provide a new body training device that can train the legs strongly by using the endless belt and also train the back muscles, abdominal muscles, arms, shoulders and the like.

[Means for Solving the Problems]

As shown in FIG. 1, the body training apparatus according to the first aspect of the present invention stretches an endless belt 6 between front and rear belt supporting rollers 4 supported by a hollow main body frame 1, and A brake device 8 capable of adjusting pressure is connected to the belt supporting roller 4, an extension frame 13 is attached to the front side of the main body frame 1 so that the extension frame 13 can be stored, and an extendable handle frame 26 is foldable at the front end of the extension frame 13. A brace 29 is pivotally attached and a brace 29 is stretched between the handle frame 26 and the main body frame 1. Further, in the body training apparatus according to the second aspect of the present invention, as illustrated in FIG. 4, the endless belt 6 is stretched between the front and rear belt support rollers 4 supported by the hollow main body frame 1.
A brake device 8 capable of adjusting pressure is connected to at least one of the belt supporting rollers 4, an extension frame 13 is mounted on the front side of the main body frame 1 so as to be stored, and a handle frame 26 is freely foldable at the front end of the main body frame 1. The pivot frame 21 is pivotally attached, and the expandable / contractible rotary frame 21 is pivotally attached to the front end of the extension frame 13 so as to be vertically rotatable, and the free end portion of the rotary frame 21 and the free end portion of the handle frame 26 are connected to each other. It is a thing.

[Action]

In the case of the body training apparatus of both the first and second modes, in order to train, the rider rides on the endless belt 6 and leans forward to grasp the handle frame 26 to adjust the pressure. Thus, while applying an arbitrary load to the endless belt 6, the left and right legs are alternately moved greatly on the endless belt 6 while pushing the handle frame 26 forward, and the endless belt 6 is circulated as if kicked backward. At this time, in the case of the first aspect,
Since the handle frame 26 has the brace 29, and in the case of the second mode, the rotating arm 21 supports it from the lower side so that it cannot fall forward. The extension frame 13 can be stored in the main body frame 1, and the handle frame 26 can be folded on the main body frame 1.

13 is installed. In this extension frame 13, the front ends 15 of the two left and right long handles 14 made of pipe material are bent downward at a right angle, and their lower ends are connected by a connecting pipe 16, and the extension frame 13 is placed in the connecting pipe 16. The left and right extension rods 17 are mounted so as to be slidable left and right in order to improve the stability of the.
The left and right long handles 14 of the extension frame 13 are fitted in the upper pipes 2a of the left and right frame portions 2 of the body frame 1 so as to be slidable back and forth, and can be stored in the body frame 1. Further, the left and right upper pipes 2a are provided with a fixing screw 18, and the left and right long handles 14 are provided with a plurality of adjusting holes 19 through which the fixing screw 18 is penetrated, and the extension frame 13 is gradually extended from the main body frame 1 to an arbitrary length. It can be extended and fixed to the main body frame 1. The left and right bearing fittings 20 are fixed to the front ends of the left and right long handles 14 of the extension frame 13, and the lower ends of the left and right vertical pipes 22 of the H-shaped turning frame 21 are pivotally supported by these bearing fittings 20. Is rotatable at its front end with respect to the extension frame 13. The left and right vertical pipes 22 are connected by a horizontal rod 23. A handle frame 26, in which the left and right arm rods 25 made of pipe material are fixed to the handle rod 24, is attached to the rotating frame 21.
25 is fitted in the left and right vertical pipes 22 of the rotating frame 21 so as to be slidable in the vertical direction, and is mounted so that the height can be adjusted. The height adjustment is the same as the adjustment of the extension frame 13, the handle frame
This is done by inserting a fixing screw 28 provided on the rotating frame 21 through a plurality of adjustment holes 27 provided on the left and right arm rods 25 of 26.
The left and right ends of the handle rod 24 are grips 24a. In order to prevent the handle frame 26 from falling forward more than an arbitrary angle, wires 29 serving as left and right braces are stretched between the left and right arm rods 25 of the handle frame 26 and the left and right upper pipes 2a of the body frame 1. To be hung. The wire 29 is fixed to the upper pipe 2a, but for the arm rod 25, the length between the wire 29 and the upper pipe 2a can be adjusted as follows. That is, as shown in FIG. 3, the wire 29 is provided with stop balls 30 at predetermined intervals, and the upper end of the vertical pipe 25 has a hole through which the stop ball 30 and the wire 29 can pass. 31 and a slit 32 for penetrating only the wire 29 are continuously provided. The body training apparatus having the above structure is used as follows. The gripping force of the brake shoe 10 of the brake device 8 is adjusted so that an arbitrary load is applied to the endless belt 6, and the body is leaned forward on the endless belt 6 and the right and left grips of the handle frame 26 are gripped. Hold the part 24a, and brake device 8
While pushing an arbitrary load on the endless belt 6, the left and right legs are alternately moved greatly on the endless belt 6 while pushing the handle frame 26 forward, and the endless belt 6 is forcedly circulated by being kicked backward. . The height of the handle frame 26 can be adjusted stepwise by the adjusting hole 27, the inclination by the wire 29, and the distance between the handle frame 26 and the endless belt 6 by the extension frame 13. To put it in the stored state, after removing the wire 29 from the handle frame 26, the left and right arm rods 25 of the handle frame 26 are stored in the left and right vertical pipes 22 of the rotating frame 21, and the left and right extension rods 17 are also stored. It is stored in the connecting pipe 16 and also an extension frame
