English Abstract


The present invention is an improvement of trampoline net structure
including a frame in circular ring form provided with multiply downward foot
trusses and a sheet unit within the frame. The sheet unit includes a net
element and a skirt element that both are connected by a connecting unit while

the net element is connected with the frame by multiply elastic units. The
improvement further includes multiply bar units that each of them as
positioned at the frame with a top end connected with a top surface of the
skirt
element. Because the net element and the frame are thoroughly segregated
by the skirt element, a user will not fall into a clearance between the net
element and the frame when jumping on the net element so as to prevent the
accident and injury.

I CLAIM:
1. An improvement of trampoline net structure comprising:
a frame in a circular ring form provided with a plurality of foot
truss extended downward;
a sheet unit provided with a bed element and a skirt element that
the net element, as peripherally provided with a plurality of elastic
unit for a connection with said frame, connected with the skirt
element by a connecting unit; and
a plurality of bar unit positioned at said frame with a top end of
each bar unit connected with a surface end of the skirt element.
2. The improvement of trampoline net structure of claim 1, wherein the
connecting unit further includes a first connector and a second
connector that the first connector is peripherally positioned at a top
surface of the net element and the second connector is positioned at a
bottom surface of the skirt element.
3. The improvement of trampoline net structure of claim 1, wherein the
connecting unit is a zip.
4. The improvement of trampoline net structure of claim 1, wherein a
circumference of the net element is peripherally provided with a
plurality of attaching element that both ends of each elastic unit are

8

respectively connected to said frame and the plurality of attaching
element.

TITLE: IMPROVEMENT OF TRAMPOLINE NET STRUCTURE
(a) Technical Field of the Invention
The present invention is related to an improvement of trampoline net
structure, particularly an improvement of trampoline that is able to
thoroughly
segregate a frame and a sheet unit of a trampoline so as to prevent an user
from injury because of falling off the trampoline.
(b) Description of the Prior Art
A trampoline of the prior art basically consists of a frame in circular or
rectangle form, which is peripherally provided with multiply foot trusses at
its
bottom circumference in order to stand on a floor, and a net unit positioned
at a
center of the trampoline that an outer circumference of the net unit is
connected to an inner circumference of the frame through multiply sets of
spring or elastic unit. When a force is applied onto the net unit, it will
deform along a normal axis with respect to its surface at a downward
displacement. When the force disappears, the multiply sets of spring or
elastic unit will provide a recovery recoil because of the deformation caused
by the downward displacement for restoring the net unit upward till its
original
position. Therefore the user can keep jumping up and down repeatedly on
the net unit in order to achieve the exercise effect. However, the trampoline

CA 02849327 2014-04-08

of the prior art is not provided with a safety device and the user will
possibly
be injured from falling into a clearance between the frame and the net unit
when the user has not acquired a mature skill or an accident takes place.
Thus the trampoline of the prior art is not sufficiently safe in operation.
Further the trampoline of the prior art can be provided with a security net
at an outer periphery in order to prevent the user from falling out. However
such security net is only positioned at the outer periphery of the trampoline
of
the prior art that cannot resolve the above-mentioned deficiency and thus does

not have adequate protection. Resolving the above-mentioned deficiency is
the objective of the present invention.

SUMMARY OF THE INVENTION
The present invention is to provide an improvement of trampoline net
structure including a frame in circular ring form provided with multiply
downward foot trusses and a sheet unit within the frame. The sheet unit
includes a net element and a skirt element that both are connected by a
connecting unit while the net element is connected with the frame by multiply
elastic units. The improvement of trampoline net structure of the present
invention further includes multiply bar units that each of them as positioned
at
the frame with a top end connected with a top surface of the skirt element.
Because the net element and the frame are thoroughly segregated by the skirt
element, a user will not fall into a clearance between the net element and the

frame when jumping on the net element so as to prevent the accident and
injury.
An objective of the present invention an improvement of trampoline net
structure is to enhance the protection of the skirt element with a multiply
directional absorbing function in order to prevent the user from injury and
falling out. The other objective of the present invention an improvement of
trampoline net structure is to resolve the frequent damage due to the stress
concentration at the connection joint of net structure of the trampoline of
the
prior art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Firstly please refer Fig. 1 through Fig. 3 illustrating a preferred
embodiment of an improvement of trampoline net structure 1 that includes a
frame 10 in circular ring form, a sheet unit 20, a connecting unit 30, an
elastic
5 unit 40 and a plurality of bar unit 50.
The frame 10 is provided with a plurality of foot truss 11 extended
downward.
The sheet unit 20 is provided with a net element 21 with a circumference
provided with a plurality of attaching element 211 and a skirt element 22.
The connecting unit 30 further includes a first connector 31 and a second
connector 32 that the first connector 31 is peripherally positioned at a top
surface of the net element 21 and the second connector 32 is positioned at a
bottom surface of the skirt element 22. The net element 21 connected with
the skirt element 22 by the connecting unit 30, which is a zip in this
preferred
embodiment.
Each elastic unit 40 has one end connected with each of the plurality of
attaching element 211, which is peripherally positioned at a circumference of
the net element 21, and the other end connected with the frame 10. Namely
both ends of the elastic unit 40 is respectively connected with the frame 10
and
the attaching element 211.

Each bar unit 50 is positioned at the frame 10 and a top end of each bar
unit 50 is connected with a top surface of the skirt element 22.
Thereby the sheet unit 20 of the embodiment of the improvement of
trampoline net structure 1 can thoroughly segregate the net element 21 and the
frame 10 so that an user will not be injured from accident of falling into a
clearance between the net element 21 and the frame 10 when exercises on the
net element 21. The safety of trampoline exercise is therefore enhanced and
then the improved trampoline is more suitable for young children playing.
