Trampoline system

Abstract

A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided in the preferred embodiment by a support system of independent poles, linked at their tops by a flexible strap or line. The trampoline may include a tubular frame supported by a plurality of legs with brackets securing the legs to the frame tube without welds. The trampoline may also include an electronic accessory that is activated or that produces an electrical signal as a result of jumping on the trampoline.

(The same principles can similarly be adapted to provide fencing around above-ground pools, thereby keeping pool toys within the pool, and providing...

Benefits of technology

[0006]One novel aspect of the preferred embodiment is the provision of a safety fence support employing poles whose tops are linked by a resilient, rather than a rigid, member. Such an arrangement permits constrained movement of each pole, better absorbing impact to or near the pole. Moreover, the resilient linking of poles allows a neighborhood of plural poles (commonly all of the poles) to absorb energy from a jumper's impact anywhere against the safety fence. The subsequent release of this energy from the flexed poles helps propel the jumper back onto the trampoline surface. (A cushioning foam sheath can be provided around each of the uprights to enhance the foregoing effects.)

[0008]Another novel aspect of the preferred embodiment is the fastening of fence netting material to the support structure by continuous lengths of elastic cording. This arrangement is simple and inexpensive to implement, while enhancing the flexible response of the fence. In a particular embodiment, the elastic cording is threaded in and out of openings in fence netting. This embodiment further includes a flexible member (e.g. nylon webbing) helically wrapped around an adjacent upright support member to couple the cord thereto at plural intermediate points therealong.

[0010]The foregoing aspects, and others described below, are equally applicable to embodiments in which the safety fence is provided as an integral component of the trampoline, and also when it is provided as an add-on accessory. By providing the safety fence as an integral part of the trampoline structure, the cost, complexity, and weight of the combined structure can be reduced.

[0011]Another novel aspect of the preferred embodiment is a mounting arrangement that permits a fence readily to be attached to trampolines of different designs.

Problems solved by technology

However, injuries have sometimes resulted when a person jumping on a trampoline would land too near the boundary of the rebounding surface and strike the trampoline frame or fall from the trampoline to the ground.

However, these devices suffer from various drawbacks, in some cases introducing their own safety concerns.

If a jumper collides with one of the rigid uprights, the support frame provides little resilience and thus poses its own risk of injury.

But these, too, suffer from various drawbacks, including complexity, difficulty of installation, and expense.
