Fold down trampoline
View Patent ↗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.
1. A trampoline with a folding frame comprising: a frame supporting a bed tensioned by springs across the frame, a horizontal frame, and multiple support rod bases; the 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 and second frame rods extend horizontally and the first frame rod has a first end and a second end and the second frame rod has a first end and a second end, wherein the first frame rod connects to the second frame rod such that the first end of the first frame rod is pivotally connected to the first end of the second frame rod through a first joint and the second end of the first frame rod is pivotally connected to the second end of the second frame rod through a second joint; wherein each of the first and second joints comprise a retaining plate, two clamping grooves, two pivot connection grooves, a first stop groove, a second stop groove, two pivots, a locating hole and a locating assembly, wherein the retaining plate is mounted to the first frame rod at a respective end of the first and second ends, 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 has an end face formed toward the respective end of the first and second ends of the first frame rod, each of the two clamping grooves are formed on a respective pair of plate sides of the retaining plate, the two pivot connection grooves extend upwardly into a pair of undersurfaces, wherein each of the pair of undersurfaces are formed on a respective lower surface of the pair of plate sides of the retaining plate, the first stop groove extending laterally from a first pivot connection groove of the two pivot connection grooves formed in one of the pair of plate sides of the retaining plate, and a second stop groove extending laterally from a second pivot connection groove of the two pivot connection grooves formed in another of the pair of plate sides of the retaining plate, the two pivots mounted on the second frame rod and configured to respectively engage the first and second stop grooves; and the locating hole formed on the second frame rod at a side of the second frame rod, wherein the locating hole k configured to receive the locating assembly that engages the two clamping grooves.
2. The trampoline with the folding frame of claim 1 , wherein each of the retaining plates of the first and second joints have stop block formed on each of the lower surfaces of the pair of plate sides, wherein each of the stop hocks define a portion of a respective stop groove of the first and second stop grooves of the retaining plates and, wherein each of the first and second stop grooves has an upper groove wall, wherein a lower groove wall is set opposite to the upper groove wall and wherein a groove sidewall is configured between the upper groove wall and the lower groove wall, wherein each of the stop blocks is Formed below the lower groove wall, and wherein each of the upper groove wall, the lower groove wall, and the groove sidewall are load bearing.
3. The trampoline with the folding frame of claim 2 , wherein the second frame rod further includes two auxiliary supports, wherein the two auxiliary supports are connected to corresponding auxiliary support bottom edge and auxiliary support pivots and wherein each of the two auxiliary supports is connected to a respective end of the first and second end of the second frame rod.
4. The trampoline with the folding frame of claim 3 , wherein each of the pair plate sides of the retaining plates of the First and second joints are parallel to each other.
5. The trampoline with the folding frame of claim 4 , wherein each of the first and second ends of the second frame rod further include a threading slot connected to the locating hole, wherein each of the locating assemblies comprise a rod and a fixture block that protrudes and extend towards an outer periphery of the rod, wherein the rod and the fixture block are configured to be inserted into the threading slot.
6. The trampoline with the folding frame of claim 5 , wherein each of the locating assemblies of the first and second joints further comprise a bumper in an arc shape, wherein an end of the bumper is connected to a first side end of the rod, while the other end of the bumper is detachably nested in a second side end of the rod.
7. The trampoline with the folding frame of claim 6 , wherein a cross-section of each of the retaining plates of the first and second joints are an inverted U-shape.
8. The trampoline with the folding frame of claim 7 , wherein the multiple support rod bases each have a pair joint pipes connected to an outer periphery of the first frame rod and the second frame rod and a leg connected to each of the pair of joint pipes.
9. The trampoline with the folding frame of claim 8 wherein the pair of joint pipes are welded to the first frame rod and the second frame rod.
