Abstract

A trampoline includes a trampoline frame including a trampoline frame ring supported by a trampoline frame. A trampoline bed is supported across the trampoline frame. The trampoline frame is foldable. Enclosure poles are oriented in a vertical orientation when the enclosure poles are in a deployed position. One or more hinge joints connect the enclosure poles to the trampoline frame. The enclosure poles are mounted to the trampoline frame ring at the hinge joints. The enclosure poles fold inward to a horizontal position when the enclosure poles fold to a folded position. The enclosure poles may overlap each other when folding to the folded position.

First claim

1 . A trampoline with a folding frame comprising:
a) a frame supporting a bed tensioned by springs across the frame, wherein the frame has horizontal frame members; b) a horizontal frame member formed as a frame unit, wherein the frame unit has a first frame rod and a second frame rod, wherein the first frame rod connects to the second frame rod; c) two locating assemblies which pass the joint of the first and the second frame rods and multiple support rod bases where the first and the second frame rods extend downwardly, wherein the first frame rod extends and includes two first ends; d) a retaining plate mounted to the first frame rod, wherein the retaining plate has a pair of plate sides, wherein the pair of plate sides extend downwardly from the retaining plate, wherein the retaining plate is mounted on the first ends of the first frame rod, wherein each retaining plate has an end face formed toward a front of the two first ends; e) two clamping grooves indented at a pair of end faces, wherein the pair of end faces is formed on the pair of plate sides; f) two pivot connection grooves that extend upwardly into a pair of undersurfaces, wherein the pair of undersurfaces are formed on the lower surface of the pair of plate sides; g) two stop grooves that extend laterally from the two pivot connection grooves; h) two pivots mounted on the second frame rod and configured to engage the two stop grooves; and i) a locating hole formed on the second frame rod at a side of the second frame rod, wherein the locating hole is configured to receive a locating assembly that engages the two clamping grooves.

2 . The trampoline with folding frame of claim 1 , wherein each retaining plate has stop blocks on the lower surface, wherein each stop groove has an upper groove wall, wherein a lower groove wall is set opposite to an upper groove wall and wherein a groove sidewall is configured between the upper groove wall and the lower groove wall, wherein each upper groove wall, lower groove wall and groove sidewall is load bearing.

3 . The trampoline with folding frame of claim 2 , wherein the second frame rod also includes two auxiliary supports, wherein the two auxiliary supports are connected to their corresponding auxiliary support bottom edges and auxiliary support pivots.

4 . The trampoline with folding frame of claim 3 , wherein the retaining plate has plate sides that are parallel to each other.

5 . The trampoline with folding frame of claim 4 , wherein the second frame rod also includes threading slots connected to corresponding locating holes, wherein the two locating assemblies each comprise a rod and multiple fixture blocks that protrude and extend towards the outer periphery of the rod, wherein each rod and its corresponding fixture block respectively respond to their respective threading slot.

6 . The trampoline with folding frame of claim 5 , wherein each locating assembly also includes a bumper in an arc shape, wherein an end of each bumper is connected to a first side end of the corresponding rod, while the other end of each bumper is detachably nested in a second side end of the corresponding rod.

7 . The trampoline with folding frame of claim 6 , wherein a cross-section of each retaining plate is in an inverted U-shape.

8 . The trampoline with folding frame of claim 7 , wherein the support rod bases have joint pipes connected to an outer periphery of the first frame rod and the second frame rod and legs connected to the joint pipes.

9 . The trampoline with folding frame of claim 8 wherein the joint pipes are welded to the first frame rod and the second frame rod.

10 . The trampoline with folding frame of claim 8 , further comprising: a trampoline frame including a trampoline frame ring supported by a trampoline frame; a trampoline bed supported across the trampoline frame; enclosure poles oriented in a vertical orientation when the enclosure poles are in a deployed position; and hinge joints connecting the enclosure poles to the trampoline frame, wherein the enclosure poles are mounted to the trampoline frame ring at the hinge joints, wherein the enclosure poles fold inward to a horizontal position when the enclosure poles fold to a folded position.

11 . The trampoline with folding frame of claim 10 , wherein the enclosure poles overlap each other when folding to the folded position.
