## Abstract

A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided by a support system of independent poles. Variable placement net fasteners also are detailed.

## Claims

### Claim 1

A trampoline having a safety enclosure, comprising:
a trampoline comprising a frame and a rebounding mat coupled to the frame via plural spring members;
a safety enclosure comprising plural independent poles extending above the rebounding mat and a flexible material coupled to the poles; and
a resilient mechanism connected between the poles and the frame (a) to store energy upon an impact to the enclosure which causes at least one entire pole to move downwardly and (b) to release energy to return the at least one pole upwardly once the impact force is removed.

### Claim 2

A trampoline having a safety enclosure, comprising:
a trampoline comprising a frame and a rebounding mat coupled to the frame via plural spring members; and
a safety enclosure comprising plural poles, with at least the lower halves of the poles extending upwardly at more than a 60 degree angle from horizontal, and a flexible material coupled to the poles; and
a resilient mechanism connected between the poles and the frame (a) to store energy upon an impact to the enclosure which causes at least one entire pole to move downwardly and (b) to release energy to return the at least one pole upwardly once the impact force is removed.

### Claim 3 (depends on 1)

The trampoline having a safety enclosure of claim 1 further comprising a plurality of base plates that are supported by the rebounding mat and that support at least some of the poles.

### Claim 4 (depends on 1)

The trampoline having a safety enclosure of claim 1 wherein the resilient mechanism comprises at least some of the springs such that downward motion of a connected pole moves one or more springs downwardly.

### Claim 5 (depends on 2)

The trampoline having a safety enclosure of claim 2 further comprising a plurality of base plates that are supported by the rebounding mat and that support at least some of the poles.

### Claim 6 (depends on 2)

The trampoline having a safety enclosure of claim 2 wherein the resilient mechanism comprises at least some of the springs such that downward motion of a connected pole moves one or more springs downwardly.

### Claim 7 (depends on 1)

The trampoline having a safety enclosure of claim 1 wherein:
the resilient mechanism comprises the rebounding mat; and
at least some of the poles are supported poles, which supported poles are supported by the rebounding mat with the supported poles positioned such that downward motion of a supported pole forces the rebounding mat to move downwardly and such that upward motion of the rebounding mat forces the supported pole upwardly.

### Claim 8 (depends on 1)

The trampoline having a safety enclosure of claim 1 wherein:
the resilient mechanism comprises at least some of the spring members that couple the rebounding mat to the frame; and
at least some of the poles are spring-connected poles, which spring-connected poles are connected to the spring members such that downward motion of a spring-connected pole forces a spring member to move downwardly and such that upward motion of the spring member forces the spring-connected pole upwardly.

### Claim 9 (depends on 2)

The trampoline having a safety enclosure of claim 2 wherein:
the resilient mechanism comprises the rebounding mat; and
at least some of the poles are supported poles, which supported poles are supported by the rebounding mat with the supported poles positioned such that downward motion of a supported pole forces the rebounding mat to move downwardly and such that upward motion of the rebounding mat forces the supported pole upwardly.

### Claim 10 (depends on 2)

The trampoline having a safety enclosure of claim 2 wherein:
the resilient mechanism comprises at least some of the spring members that couple the rebounding mat to the frame; and
at least some of the poles are spring-connected poles, which spring-connected poles are connected to the spring members such that downward motion of a spring-connected pole forces a spring member to move downwardly and such that upward motion of the spring member forces the spring-connected pole upwardly.
