SOLUTION: A trampoline cloth is fixed to a frame equally divided into four parts via a spring, a folding hinge is provided between the corresponding frames at a center line, and the axis of the folding hinge is the axis of the trampoline cloth. Vertical hinges are provided between the remaining frames, the axes of the flat hinges are parallel to the axes of the trampoline cloth, and after folding the hinges first, further flatten under the action of the spring. The hinge is automatically folded flat, and this structure allows storage,
It is a folding trampoline that saves driving space, reduces transportation costs, can be folded quickly and easily, and can be used widely for exercise or play.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of health promotion device, and more particularly to a folding trampoline.

[0002]

[Prior art]

 Trampolines are a type of health-enhancing device that can be used by jumping over them, but they are generally relatively large in area and volume and can be used safely. However, if the area and volume were large, private space for storage and transportation was large, and the fare was high.

[0003]

[Problems to be solved by the invention]

 It is an object of the present invention to provide a kind of folding trampoline which is quick and easy when folded, and can be automatically folded flat after folding to save storage and transportation space.

[0004]

[Means for Solving the Problems]

 According to the invention of claim 1, the trampoline cloth 1 is fixed to the frames 3a, 3b, 3c, 3d equally divided into four parts via the spring 2, and the corresponding frames 3a and 3d and 3b and 3c at the center lines. Hinges 5 are provided between them, the axis 7 of which is perpendicular to the axis of the trampoline cloth 1 and the flat hinges 4 between the remaining frames 3a and 3b, 3c and 3d. Is provided, and the axis 6 of the flat hinge 4 is made parallel to the axis of the trampoline cloth 1 to provide a folding trampoline. The invention of claim 2 is characterized in that the ends of the hinge arm 8 of the flat hinge 4 and the hinge arm 9 of the folding hinge 5 are mounted in the inner hole 10 of the frame 3. 1 is a folding trampoline.

[0005]

[Embodiment of the invention]

 In the present invention, the trampoline cloth is fixed to a frame equally divided into four parts via a spring, and a folding hinge is provided between the frames corresponding to the center line, and the axis of the folding hinge is the axis of the trampoline cloth. A flat hinge is provided between the remaining frames, and the axis of the flat hinge is parallel to the axis of the trampoline cloth.

[0006] According to the above structure, after the folding hinge is first folded, the flat hinge can be further automatically folded under the action of the spring. With this structure, the space for storage and operation can be saved, and the transportation cost can be reduced. The foldable trampoline can be folded quickly and easily, and can be used widely for exercise or play.

【Example】

 As shown in FIGS. 1, 2, and 3, the trampoline cloth 1 is fixed to frames 3a, 3b, 3c, and 3d equally divided by a spring 2 and the frames 3a and 3d corresponding to the center line. And a folding hinge 5 is provided between 3b and 3c, the axis 7 of said folding hinge 5 being perpendicular to the axis of the trampoline cloth 1 and the remaining frames, ie between the frames 3a and 3b, 3c and 3d. A flat folding hinge 4 is provided, the axis 6 of the flat folding hinge 4 is made parallel to the axis of the trampoline cloth 1, and the axis of the trampoline cloth 1 is immediately set to the axis passing through the center of the circle of the trampoline cloth 1. Is perpendicular to the plane of the trampoline cloth 1. The ends of the hinge arm 8 of the flat folding hinge 4 and the hinge arm 9 of the folding hinge 5 are mounted in the inner hole 10 of the frame 3. Of course, the hinge arm can also be attached to the outer wall of the frame 3, except that the axis 7 of the folding hinge 5 is perpendicular to the axis of the trampoline cloth 1 and the axis 6 of the flat hinge 4 is the axis of the trampoline cloth 1. It must be guaranteed that they are parallel to the axis. This guarantees automatic flat folding after folding.

As shown in FIGS. 1, 4, and 5, when the frames 3a and 3d and 3b and 3c are folded using force, the frames 3a and 3d and 3b and 3c move the shaft 7 of the folding hinge 5 together. Folded as center. This is possible because there is a soft trampoline cloth 1 between the frames. After the folding, the frames 3a and 3b, 3c and 3d are further automatically folded about the shaft 6 of the flat hinge 4 by the elastic action toward the center of the spring 2. This is as shown in FIG.

[0009]

[Effect of the invention]

 With the above structure, the present invention allows the folding hinge to be folded automatically under the action of the spring after folding the folding hinge first.This structure saves space for storage and operation. It is a folding trampoline that can be folded quickly and easily, reducing transportation costs and widely used for exercise or play.
