Abstract

This invention refers to a folded trampoline which can be installed easily. It is equipped with tubes aimed at supporting bed surface as well as feet outside the bottom of the tubes. There are folding devices between the tubes and the feet, which consist of exterior folding units, interior folding units, handle, plug pin and reset spring. The exterior folding units which are furnished with locating holes, plus the interior folding units, are connected with tubes, and the feet linked with the inner side of the exterior folding units are articulated with the interior folding units and armed with through-holes which plug pin can go through. This invention has several elastic cords corresponding to fixed units. During installation, one end of the elastic cord will be inserted into the fixed unit, and the other end will go through the ring and the tube successively. After passing through all the rings of elastic cord between two legs, the other end shall be inserted into the fixed unit of the first neighboring elastic cord to assure quick installation.

Description

TECHNICAL FIELD

This invention refers to an easily installed folded trampoline in the technical field of trampoline.

TECHNICAL BACKGROUND

Bedjump has become increasingly popular among ordinary families in daily life as a sport and recreational activity. Today, the trampoline in the market is made of iron tube, which leads to heavy product and gives rise to rust easily. This product will take up much space when not used, and it is not convenient to install since the jumping sheet is connected with only one elastic cord.

CONTENTS OF INVENTION

To address problems above, this invention proposes one folded trampoline which can be easily installed and stored.
To achieve the aim above, this invention puts forward a scheme as follows:
The folded trampoline is equipped with tubes aimed at supporting bed surface as well as feet outside the bottom of the tubes. There are folding devices between the tubes and the feet, which consist of exterior folding units, interior folding units, handles, plug pins and reset springs. The exterior folding units which are furnished with locating holes, plus the interior folding units, are connected with tubes, and the feet linked with the inner side of the exterior folding units are articulated with the interior folding units and armed with through-holes which plug pin can go through. The upper part of the handle is linked with the inner wall of the feet, and the other end is upturned outwards. The plug pin is linked with the upper part of the handle through locating hole and through-hole.
The two ends of the plug pin differ in diameter and there is a step surface between these two ends.
One side of the through-hole near the handle is equipped with spring stop.

- There is a reset spring between the step surface of the plug pin and the spring stop.

The tube is characterized by round shape or polygon.
Beneficial results of this invention are as follows: this invention has several elastic cords corresponding to fixed units. During installation, one end of the elastic cord will be inserted into the fixed unit, and the other end will go through the ring and the tube successively. After passing through all the rings of elastic cord between two legs, the other end shall be inserted into the fixed unit of the first neighboring elastic cord to assure quick installation.

SPECIFIC IMPLEMENTATION MODE

Description on the specific implementation mode of this invention will be made in combination with examples for the sake of better understanding of this invention.

EXAMPLE

As shown by FIGS. 1-3, the folded trampoline which can be easily installed is equipped with tubes 1 aimed at supporting bed surface as well as feet 2 outside the bottom of the tubes 1. There are folding devices 3 between the tubes 1 and the feet 2, which consist of exterior folding units 3-1, interior folding units 3-2, handles 3-3, plug pins 4 and reset springs 7. The exterior folding units 3-1 which are furnished with locating holes 6, plus the interior folding units 3-2, are connected with tubes 1, and the feet 2 linked with the inner side of the exterior folding units 3-1 are articulated with the interior folding units 3-2 and armed with through-holes 5 which plug pin 4 can go through. The upper part of the handle 3-3 is linked with the inner wall of the feet 2, and the other end is upturned outwards. The plug pin 4 is linked with the upper part of the handle 3-3 through locating hole 6 and through-hole 5. The two ends of the plug pin 4 differ in diameter and there is a step surface 4-1 between these two ends. One side of the through-hole 5 near the handle 3-3 is equipped with spring stop 5-1. There is a reset spring 7 between the step surface 4-1 of the plug pin 4 and the spring stop 5-1. Every interior folded unit 3-2 is connected with fixed unit 9 of the elastic cord.
When this invention is used, the handle 3-3 shall compress the spring with plug pin for the sake of inward compression. The feet can be folded inwardly as the plug pin 4 moves away from locating hole 6 of the exterior folding unit 3-1. During installation, the plug pin 4 shall be aligned with locating hole 6 and reset by reset spring 7 so that the feet 2 will stand firmly after plug pin 4 passes through locating hole 6. In this invention, the tube characterized by round shape or polygon is easy to use and occupy little space after being folded.
All above are preferential examples of this invention. It is worth noticing that on the premise of following the principle of this invention, ordinary technicians in this technical field are allowed to make improvements and modifications that shall also fall within the protective scope of this invention.
