NEW Trampoline
A new trampoline, belonging to the field of manufacture technique for trampolines, has an advantage design. An outside frame has short pole 3 fixed under its lower part. A bounce surface 9 connecting with spring components 8 is located in the outside frame. Foot support 5 connects with connection pole 4 which is under the short pole 3. Fence protect stem 7 fastens with the short pole 3 and foot supporter 5 tightly. The outside frame is composed by sleeve joining of 3 to 8 pieces of long or short frame segments 1, 2 alternately. The short pole 3 is fixed at the point near the ends of long segment 1. The length ration between the long frame segment 1 and shot frame segment 2 can be 1.1 to 2:1. The distant L between the fixing point H at which the short poles 3 is fixed to the long frame segment 1 and the connecting point A of the end of long frame segment 1 can be 5-30 cm. The short pole 3, foot supporter 5 and fence protect stems 7 can be held together by an embrace clamp 6 with hinge. Thereby, the design for outside frame is reasonable, makes the foot supporters as equilateral location, intensifies the structure strength of the outside frame, prevents collapse of the outside frame and avoids the structure weakness at the connecting points, makes shape beauty and convenience in assembly and effectiveness in manufacture.
This application claims the priority benefit of the Chinese patent application No. 200520013344.2 filed on Jul. 14, 2005.
FIELD OF THE INVENTIONThis invention involves a kind of new trampoline, belonging to the field of manufacture technique for trampolines.
BACKGROUND OF THE INVENTIONThe trampoline has a circular frame, a bounce surface connected with many spring components is located in the circular frame, a safe ring fence that is higher than the bounce surface is established on the outer circle of the bounce surface. The frame structure of trampoline usually comprises an outside frame, short poles, connection poles, foot supporters and fence protect stems, etc. Usually the circle frame structure is divided into several segment frames for the sake of the convenience in manufacture and carriage, the several segments can be assembled together by “sleeve coupling way.”
Refer to
The purpose of the present invention is to provide a new trampoline having reasonable design, strong strength to anti-impact for the outside frame and whole frames, even distribution of the safe ring fence, shape beauty, convenience in assembly and effective in manufacture.
The new trampoline of present invention comprises an outside frame with short poles fixed under its lower part, a bounce surface connected many spring components is located in the outside frame, foot supports located under the short poles, fence protection stems fastened with the short pole and foot supporter tightly, characterized in that the outside frame is composed by sleeve jointing of 3 to 8 pieces of long or short frame segments alternately, the short pole is fixed at the position near the ends of long segment.
The length ration between the long segment frame and shot segment frame can be 1.1 to 2:1.
The distant between the fixing point H at which the short poles is fixed to the long segment frame and the ends of long frame segment can be 5-30 cm.
The short pole, foot supporter and ring fence protect stem can be hold together by an embrace clamps with hinge.
A connection pole is located between said short pole and said foot supporter and connected therein.
The long segment frame, short segment frame, shot pole, connection pole, foot supporter and fence protect stem are hollow tube with a presetting diameter.
The foot supporter can be a U shape tube or W shape tube or V shape tube (see
The outside frame is composed by sleeve coupling of 3-6 pieces of long and short segment frames alternately. The short pole is located near the ends of long segment frame. Thereby, the design for outside frame is reasonable, makes the foot supporters as equilateral location, intensifies the structure strength of the outside frame, prevents collapse of the outside frame and structure weakness at the connecting points, and avoids to use screw etc. complex manufacture processes. The new structure for holding the fence protect stem with the shot pole and the foot supporter can prevent collapse of the combination of the short pole, connection pole, and foot supporter. Thereby, the frame structures in the new trampoline are joined as a whole of body.
BRIEF DESCRIPTION OF THE DRAWINGS
As shown in the Figs, long segment frame 1, short segment frame 2, short pole 3, connection pole 4, foot supporter 5, embrace clamp with hinge 6, fence protect stem 7, spring component 8, bounce surface 9, equal divided segment frame of the prior art 10.
DETAIL DESCRIPTION OF THE INVENTIONThe new trampoline of present invention has following structure. An outside frame has short pole 3 fixed under its lower part. A bounce surface 9 connecting with spring components 8 is located in the outside frame. A Foot support 5 connects with the short pole 3 through a connection pole 4. A Fence protect stem 7 fastens the short pole 3 and the foot supporter 5 tightly. The outside frame is composed by 3 to 8 pieces of long or short frame segments 1, 2 alternately through sleeve joining way. The short pole 3 is fixed at the point near the ends of long segment 1. The length ration between the long frame segment 1 and shot frame segment 2 can be 1.1 to 2:1. The distant L between the fixing point H at which the short poles 3 is fixed to the long frame segment 1 and the connecting point A of the end of long frame segment 1 can be 5-30 cm. The short pole 3, foot supporter 5 and fence protect stems 7 can be held together by an embrace clamp 6 with hinge.
