The second elastical cloth is included, connecting rod, four end to end formation of connecting rod are provided between two support legs of arbitrary neighborhood
The edge of frame, second elastical cloth is fixed on frame.In this way, the people light to weight, main when bouncing on trampoline
The first elastical cloth is relied on, for the people of heavier-weight, when spring, since inertia is larger, the first elastical cloth is sunk to and second
At elastical cloth, at this time, the coefficient of elasticity of the first elastical cloth and the second elastical cloth is added the coefficient of elasticity for being just equal to trampoline, therefore
The sinking tendency that the big people of weight can be slowed down rapidly, allows him to spring back as early as possible, avoids and ground face contact.Therefore the present invention can fit
The people of different weight is answered to use.
In above-mentioned technical proposal, it is preferred that four bars for forming the frame are in same plane, and the frame and institute
Frame is stated to be arranged in parallel.It is the same that the distance that may insure that hostage's signature is sunk is arranged in parallel, the rebound that trampoline obtains at various locations
Effect is the same.
In above-mentioned technical proposal, it is preferred that it further include rod, the rod is arranged in the outside of the frame, and described
One elastical cloth is fixed on the rod after bypassing the frame, and push rod is slidably connected in the support leg, the push rod
One end is connected with rod, and the other end of the push rod passes through the support leg, is provided with spring on the push rod, the spring
Both ends of the surface are located on the rod and the support leg.Under normal condition, the first elastical cloth under the action of the spring, the position at both ends
It sets relatively far apart, then for people when trampoline is in the stage pressed down, the first elastical cloth increases the pulling force of rod, and rod overcomes
The thrust of spring is moved toward force direction, and spring is compressed, and when being in ascent stage on trampoline, spring restores people, bullet
Spring can be converted into the thrust to people to the pulling force of rod, can be jumped with power-assisted people higher.
In above-mentioned technical proposal, it is preferred that passing through for the rod is provided with gear on the position stretched out after the support leg
Circle, the diameter of the retaining ring are greater than the diameter in the support leg with the through-hole of rod cooperation.
In above-mentioned technical proposal, it is preferred that be fixed with baffle at the top of the frame, first elastical cloth passes through described
It is connected behind gap between baffle and the frame with the rod.
This beneficial effect is: the people light to weight relies primarily on the first elastical cloth, for body when bouncing on trampoline
The heavier people of weight, when spring, since inertia is larger, the first elastical cloth sink to at the second elastical cloth, at this time, the first elasticity
The coefficient of elasticity of cloth and the second elastical cloth is added the coefficient of elasticity for being just equal to trampoline, therefore can slow down the big people's of weight rapidly
Sinking tendency allows him to spring back as early as possible, avoids and ground face contact.Therefore the people that the present invention is adapted to different weight uses.
Detailed description of the invention
With reference to the accompanying drawings and examples to this further explanation.
Fig. 1 is top view of the invention.
Fig. 2 is the partial schematic diagram of side
Fig. 3 is schematic diagram when Fig. 2 is in use state.
Specific embodiment
In fig. 1-3, with the trampoline of multilayer elastic cloth, including frame 1, the first elastical cloth 21,22 and of the second elastical cloth
