Trampoline {omitted}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kind of trampoline, and relates to an improved trampoline belonging to the field of athletic apparatus according to International Patent Classification (IPC) classification

The trampoline is usually provided with a tight jumping surface between the frames, and the frame and the jumping surface are connected using an elastic member so that the user can perform various jumping operations on the jumping surface.

Conventional trampoline adopts a method of connecting a jumping surface and a frame with a spring. For example, a Chinese trampoline trampoline filed in 2013.11.08 is an open publication with a public notice number CN203565690U, Trampoline was released. However, such a trampoline is very complicated to install before use and takes a long time to install.

As shown in Fig. 1, the above-mentioned spring is replaced with a single elastic rope A, which is a method of mainly bonding one elastic, elastic, elastic sheet C to the frame B. The above structure is disadvantageous in that the installation is cumbersome and takes a lot of time. According to the experiment, it takes 2 hours and 30 minutes when two adult men construct the trampoline of the above structure. In addition, The intervals between the frames are not the same and the elastic sheet can be displaced from the center.

2, another trampoline is obtained by replacing one spring with an elastic rope E provided with one positioning ball D and positioning the periphery of the elastic sheet C on the positioning ball D, Wherein the elastic rope E is provided with a tool and is wound around the elastic sheet C and the frame B so that the positioning rods E and D are fixed to the frame B via the plurality of elastic ropes E, So that the operation is difficult and cumbersome, and the elastic sheet may deviate from the center.

Therefore, the present inventor has invented the present invention considering improvement of the conventional trampoline structure.

With respect to the disadvantages of the prior art, the present invention relates to an elastic rope fixing sheet, which uses an elastic rope structure, fixes the elastic rope through the elastic rope fixing sheet, realizes simple and quick fixing of the elastic rope, and further achieves a simple and quick installation purpose of the trampoline I want to.

In order to achieve the above object, the present invention is implemented through the following technical solutions:

In the trampoline of the kind, the trampoline includes a jumping sheet connected to the frame and the elastic rope through the frame, a support leg is provided at the lower end of the frame, and the trampoline further includes one or more elastic rope fixing sheets, Each elastic rope fixing sheet is fixed at any position on the support leg or frame.

In addition, two fastening grooves or two or more fastening grooves are formed in the respective elastic rope fixing sheets, and the fastening grooves are engaged with the elastic rope, thereby realizing the fixing of the elastic rope.

Further, a fixing belt is provided on the circumference of the jumping seat, and the position and quantity of the fixing belt correspond to the number of the supporting legs or the number of the supporting legs.

The fastening belt is also overlaid or tied to a support leg or frame to form a positioning structure of the jumping sheet.

Further, a plurality of fabric belts, which are aligned with the elastic rope on the side of the jumping sheet, are distributed; A positioning mark is provided on the elastic rope, and the number of the positioning marks and the number of the fabric belts coincide with each other so that one or more positioning marks correspond to one fabric belt, thereby realizing positioning in the process of installing the elastic rope .

Further, the trampoline further includes a position restricting clamp for clamping the elastic rope using a fabric belt and a positioning mark.

In addition, there is no particular requirement for the contour of the position limiting clamp, which uses a positioning mark on the fabric belt and the elastic rope to allow the elastic rope to maintain a constant length between the fabric belt and the frame, It is necessary to provide a predetermined resistance capable of fixing the elastic rope so that the rope does not become loose.

The trampoline further includes a decorative cover which is provided on the elastic rope fixing sheet and covers a joint portion between the fixing sheet and the elastic rope.

In addition, the user can adjust the length of the elastic rope according to the degree of elasticity required to form a knot, and the purpose of elasticity control is achieved by fixing the rope knot to the fixing sheet.

Compared to the prior art, the advantages of the present invention are as follows:

1. The present invention uses a resilient rope structure and fixes the resilient rope through the resilient rope fixing sheet to realize a simple and quick fixation of the resilient rope, thereby achieving a simple and quick installation purpose.

2. In the present invention, when the fixing belt is provided on the jumping sheet and the fixing belt is inserted in the position of the corresponding supporting leg in the process of installing the jumping sheet, positioning of the jumping sheet can be realized, Do.

3. In the present invention, the positioning marks are provided on the elastic ropes, and each of the positioning marks can be associated with one of the fabric belts. In the process of installing the elastic ropes, the corresponding positioning marks are passed through the fabric belts, It is possible to effectively prevent the jumping sheet from being biased to one side, and at the same time, the speed of installation is also increased.

4. The present invention adds a design of a position limiting clamp for positioning the elastic rope in the process of installing the elastic rope so that there is no possibility of occurrence of a phenomenon that the elastic rope can not be adjusted due to the increase in the firing resistance due to its elastic restoring force, The installation of the rope can be surely guaranteed.
