Wheel assembly for trampolines |
摘要 |
A wheel assembly for attachment to the leg of a trampoline has means for moving the wheel from a first raised position where the wheel is not supporting the trampoline leg above the ground, to a second position where the wheel is supporting the trampoline leg above the ground. In that way the trampoline can be rolled on wheels without having to subsequently remove the wheel assemblies for storage.
