Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a training running machine, and more particularly, to a training running machine in which a handrail can be folded and contracted to reduce a storage space.

[0002]

[Prior art]

 As shown in FIG. 1, a conventional running machine 10 for training mainly attaches an endless rotating belt 12 to the end frames with tube rolls around the machine frame 11 which has a substantially rectangular shape when viewed from above, and attaches the center frame of the machine frame 11 to the front edge. The instrument panel support frame 13 is vertically and pivotally connected to the upper part of the handrail, and the central portion of the front end of the handle portion 21 of the handrail 20 having a substantially U shape is screwed to the upper end of the instrument panel support frame 13 by a bolt 14 to fix the handrail 20 to the handrail 20. Both ends are pivotally attached to both sides of the machine frame 11. In use, the user grips the handle portion 21 of the handrail 20 with both hands and walks or runs the endless rotation belt 12 backwards with his legs. The running machine 10 for training is stored. However, the handrail 20 and the instrument panel support frame 13, which are upright and convex from the machine body frame 11, are voluminous and take a considerable amount of space, and when the training running machine 10 is folded and stored, the current layout is small. When I live in a house, I'm worried about the storage space. That is, as shown in FIG. 2, first, the bolt 14 is loosened and removed, and then the handrail 20 and the instrument panel support frame 13 are separated from each other, and the handrail 20 is tilted and folded to face the front end of the handrail 20. After it is laid flat on the machine body frame 11 so that it extends out of the machine body, the instrument panel support frame 13 is further folded in the opposite direction along the surface of the machine body frame 11, so that the entire folded machine can handle the handrail 20. Since it takes longer to squeeze out, and it also requires a considerable height to lean against the wall, there is a problem that the space required for storage cannot be reduced.

[0003]

[Problems to be solved by the device]

 In view of the above problems in the conventional training running machine, it is an object of the present invention to provide a training running machine that can be reduced in height when folded to reduce the storage space.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, the instrument panel column is tilted and erected vertically at the center of the front end of the machine frame to which the endless rotary belt is attached, and the both ends of the opening are opened at the upper end of the instrument panel column. A training running machine in which the center of the front end of a handrail that extends rearward and has a substantially U-shape is pivotally attached, and both ends of the opening of the handrail are pivotally mounted at appropriate positions on both sides of the machine frame. The upper pipe is formed by a handle portion having a substantially U-shaped rearward facing opening, both upper pipes integrally connected to both ends of the opening of the handle portion, and both lower pipes pivotally connected to the both upper pipes. And the lower pipe and the pivot axis of the lower pipe, the handle of the handrail and the instrument panel support, and the lower pipe and the pivot of the side of the fuselage frame. Pivots of the two upper pipes and the lower pipe Configured axis form isosceles triangle in which the vertex.

Then, a U-shaped pivoting ear that is fitted to the lower half of the lower pipe and is open at both ends is provided at the front end of the lower pipe, and is vertically fixed to the outer peripheral surface of the rear end of the upper pipe. The two pivoted connecting pieces are extended and pivoted between the pivoting ears, and a pair of fixing holes corresponding to each other are formed at appropriate places near the lower ends of the pivoting ears of the lower pipe to form a rear end outer peripheral surface of the upper pipe. A circular hole corresponding to the fixing hole is formed in the inner side of the circular hole, and the locking projections provided at both ends of the substantially V-shaped elastic piece are fitted and locked in the inner hole of the circular hole. The upper pipe is exposed to the outer peripheral surface of the fixing hole of the lower pipe which is connected to the upper pipe through each of the fitted and locked circular holes, and the upper pipe is curved in a gentle upward curve and the lower pipe is gently curved. When the upper and lower pipes are folded on the machine frame, they are formed in the shape of a curve that drops in the middle. It is even more preferable to exhibit parallel curving in the same direction so as to overlap each other.

According to the present invention configured as described above, the pivotal axis of the upper pipe and the lower pipe, the pivotal axis of the handrail handle and the instrument panel support, and the lower pipe and the body frame side The relative position of the pivot axis with respect to the side forms an isosceles triangle with the pivot axis of the upper pipe and the lower pipe, which is approximately one in side view, as the apex, so when folding, the handrail has a By loosening the pivotal connection between the handle and the upper end of the instrument panel strut, and pressing both locking projections of the elastic piece at the same time to move it out of the fixing hole of the lower pipe, the fixing locking relationship between the upper pipe and the lower pipe. Is released, and the handle, the upper pipe, and the lower pipe are pivotally rotatable, and at this time, the upper end of the instrument panel support is pushed downward and rearward of the machine frame to move the instrument panel support to its lower end. On the fuselage frame centering around the axis of tangency with the ear of the fuselage frame When it is pushed down so that it overlaps with the surface, the handrail is simultaneously displaced and pressed, and the handpiece part interlocks with the upper pipe while rotating around the axis insertion point with the upper end of the instrument panel strut, and the upper pipe While tilting and pivoting rearward about the pivot axis of the lower pipe (that is, the apex of the above-mentioned isosceles triangle), the pivot axes of the upper pipe and the lower pipe move toward the front end of the fuselage frame. Then, the lower pipe falls and overlaps on the upper surface of the body frame around the pivotal contact point of the rear end with the side edge of the body frame, and when the upper pipe and the lower pipe are completely rotated and overlapped, Since it has a curved shape, it can be easily and easily folded without protruding from the front and rear ends of the machine frame without interfering with the lower pipe, upper pipe, instrument panel support and handle part. Eating It is possible only to reduction of the collection space let not minute.
