NEW Trampoline
Abstract
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.

Description
CROSS REFERENCE TO THE RELATED PATENT APPLICATION
[0001] This application claims the priority benefit of the Chinese
patent application No. 200520013344.2 filed on Jul. 14, 2005.
FIELD OF THE INVENTION
[0002] This invention involves a kind of new trampoline, belonging
to the field of manufacture technique for trampolines.
BACKGROUND OF THE INVENTION
[0003] The 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."
[0004] Refer to FIGS. 1 and 2, the frame structure of a common
trampoline mainly is composed by an outer frame including several
equal divided pipe pieces 10, a short pole 3 is fixed at the center
of the equal divided pipe piece 10, a foot support 5 is connected
with the short pole 3 by a connection pole 4, a fence protect stems
7 is fastened with the connection pole 4 tightly. Therefore, the
weakest point for stress in this kind of frame structure is at the
coupling point A between the two equal divided pipe pieces 10. When
this coupling point A is subjected to certain external force, the
stability of outside frame will be affected seriously and the frame
would be folded easily. For increasing the strength of the outer
frame, take screw to fix at the coupling point A. However, this
measure increases the difficulty and cost of manufacture.
SUMMEARY OF THE INVENTION
[0005] 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.
[0006] 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.
[0007] The length ration between the long segment frame and shot
segment frame can be 1.1 to 2:1.
[0008] 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.
[0009] The short pole, foot supporter and ring fence protect stem
can be hold together by an embrace clamps with hinge.
[0010] A connection pole is located between said short pole and
said foot supporter and connected therein.
[0011] The long segment frame, short segment frame, shot pole,
connection pole, foot supporter and fence protect stem are hollow
tube with a presetting diameter.
[0012] The foot supporter can be a U shape tube or W shape tube or
V shape tube (see FIG. 5).
[0013] 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.

DETAIL DESCRIPTION OF THE INVENTION
[0021] The 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.
[0022] The FIGS. 3 and 4 show a best embodiment of the present
invention. Several pieces of long segment frame 1 and short segment
frame 2 are connected alternately to compose a outside frame by
sleeve joining; it means that each segment frame has a out-diameter
reduced end, which is inserted into the inner hole of the end of
other segment frame (see FIG. 6). Two short poles 3 are welded at
the position near by the connecting point A of the ends of the long
segment frame 1 respectively. The foot supporter 5 is connected
with the bottom end of the short pole 3 through the connection pole
4 by sleeve joining. The fence protect stem 7 is tightly fixed with
the short pole 3 and foot supporter 5 by the embrace clamps 6 with
hinge. The outside circle frame of the trampoline is therefore
completed. Thereafter, using the spring components 8 attaches the
bounce surface 9 on the outside circle frame. Put protection pad on
the bounce surface 9. A trampoline having the bounce surface with
presetting high position is constructed. People can use the
trampoline after wrapping a ring safe fence according to the high
of ring fence protect stem 7.
