Definitions

  • the present invention relates to the technical field of trampolines, and in particular, to a safety trampoline.
  • the existing trampoline mainly includes a trampoline frame, a jumping mat, a spring, a trampoline pad and the like, wherein the jumping mat is connected to the trampoline frame through the spring, and the trampoline pad is sleeved at the periphery of the trampoline frame and is used to cover the spring for protection.
  • the spring stretches and contracts so as to provide a jumping force.
  • the trampoline pad and the jumping mat are still mutually separated and do not form a whole body; therefore, when a user jumps, there will be a gap between the trampoline pad and the jumping mat due to the deformation of the spring, the user's feet or body will easily slip into the gap between the trampoline pad and the jumping mat to be sprained, scratched or be pinched by the spring, thereby having a certain potential safety hazard.
  • the present invention with the publication number CN206526441U discloses a protective structure between the trampoline pad and the jumping mat.
  • the enclosure and the jumping mat are sewed and connected by the perforated fabric belt and the rope, thereby preventing the user's feet or body from slipping into the gap of the trampoline.
  • the trampoline with this structure has a complicated production process and high production cost, and is tedious to mount.
  • a main objective of the present invention is to overcome the defects in the prior art and provide a safety trampoline, thereby preventing a user's feet or body from slipping into a gap at the periphery of a jumping mat when the user jumps and avoiding injury to the user.
  • the safety trampoline is safer to use, simple in structure, simple and convenient to mount, and low in production cost.
  • a safety trampoline includes a trampoline frame, trampoline supporting legs, a jumping mat, several springs and an elastic protective sleeve, wherein the trampoline supporting legs are supported at the bottom of the trampoline frame, the jumping mat is connected to the trampoline frame through several springs distributed at the periphery of the jumping mat, the periphery of the jumping mat is connected to several connecting rings for connecting the springs, the elastic protective sleeve is ring-shaped, several net holes for being connected to the several connecting rings in a matched manner are formed at one end of the elastic protective sleeve, the connecting rings pass through the net holes, so that the elastic protective sleeve is clamped between the springs and the jumping mat, the other end of the elastic protective sleeve is turned to the bottom of the trampoline frame, and the edge is tied tightly and clamped at the bottom of the trampoline frame to cover the upper parts of the springs.
  • the safety trampoline further includes a trampoline pad, wherein the trampoline pad is sleeved at the periphery of the trampoline frame and is used to cover the springs, and the elastic protective sleeve wraps the trampoline pad.
  • the elastic protective sleeve is elastic meshed fabric with net holes throughout.
  • connecting rings are triangular rings.
  • edge of one end of the elastic protective sleeve located at the bottom of the trampoline frame is tied tightly through a pulling rope movably penetrating through the periphery of the elastic protective sleeve.
  • edge of one end of the elastic protective sleeve located at the bottom of the trampoline frame is tied tightly through an elastic belt connected to the periphery of the elastic protective sleeve.
  • hooks are formed at two ends of the spring respectively, a hanging hole for connecting the spring is formed in the trampoline frame, the hook at one end of the spring is connected to the hanging hole, and the hook at the other end of the spring is connected to the connecting ring.
  • connecting ring is connected to the jumping mat through a connecting fabric sleeve passing around the connecting ring.
  • trampoline supporting legs are detachably connected to the bottom of the trampoline frame, and an avoidance channel for the trampoline supporting legs to pass through is formed in the elastic protective sleeve and/or the trampoline pad.
  • trampoline frame is movably embedded on the trampoline supporting legs.
  • the present invention compared with the prior art, the present invention has the following beneficial effects:
  • the jumping mat and the trampoline pad are integrally connected, so that when a user jumps on the trampoline, his/her feet or body can be blocked on the trampoline by the elastic protective sleeve and will not slip into the gap around the jumping mat, thereby avoiding damage to the user and achieving use safety;
  • one end of the elastic protective sleeve is matched with and connected to the connecting ring on the edge of the jumping mat through the net hole, and the other end of the elastic protective sleeve is tied tightly through the pulling rope or the elastic belt, so the safety trampoline is simple in structure and simple and convenient to mount; furthermore, compared with the structure in which the trampoline pad and the jumping mat are sewed and connected, the production can be greatly reduced.
  • FIG. 1 is a top view of an overall structure of a safety trampoline according to an embodiment 1 of the present invention
  • FIG. 2 is a three-dimensional diagram of a partial structure of a safety trampoline according to an embodiment 1 of the present invention, and shows a mounting structure of a trampoline pad;
  • FIG. 3 is a three-dimensional diagram of a partial structure of a safety trampoline according to an embodiment 1 of the present invention, and shows a connection structure of a jumping mat, a spring and a trampoline frame;
  • FIG. 4 is a three-dimensional diagram of a partial structure of a safety trampoline according to an embodiment 1 of the present invention, and shows a mounting structure of an elastic protective sleeve.
  • a safety trampoline according to the present invention includes a trampoline frame 1 , trampoline supporting legs 2 , a jumping mat 3 , several springs 4 , a trampoline pad 5 and an elastic protective sleeve 6 .
  • the jumping mat 3 is connected to the trampoline frame 1 though several springs 4 distributed at the periphery of the jumping mat.
  • the trampoline frame 1 is a round frame spliced by several steel pipes.
  • the periphery of the jumping mat 3 is connected to several connecting rings 7 for connecting the springs 4 , each connecting ring 7 is a triangular ring, and the connecting ring 7 is connected to the jumping mat 3 through a connecting fabric sleeve 9 passing around the connecting ring 7 .
  • Hooks 41 are formed at two ends of each of the springs 4 respectively, the trampoline frame 1 is provided with a hanging hole 11 for connecting the spring 4 , the hook 41 at one end of the spring 4 is connected to the hanging hole 11 , and the hook 41 at the other end of the spring 4 is connected to the connecting ring 7 .
  • the trampoline pad 5 is sleeved at the periphery of the trampoline frame 1 and is used to cover the spring 4 .
  • the elastic protective sleeve 6 is elastic meshed fabric with net holes throughout and is ring-shaped, several net holes 61 for being matched and connected with several connecting rings 7 are formed at one end of the elastic protective sleeve 6 , the connecting ring 7 pass through the net hole 61 , so that the elastic protective sleeve 6 is clamped between the spring 4 and the jumping mat 3 , the other end of the elastic protective sleeve 6 is turned to the bottom of the trampoline frame 1 , and the edge is tied tightly and clamped at the bottom of the trampoline frame 1 through a pulling rope which movably passes through the periphery of the elastic protective sleeve 8 to cover the upper part of the spring 4 .
  • the elastic protective sleeve 6 wraps the trampoline pad 5 .
  • the trampoline supporting legs 2 are supported at the bottom of the trampoline frame 1 .
  • the trampoline supporting legs 2 are detachably connected to the bottom of the trampoline frame 1 , and avoidance channels for the trampoline supporting legs 2 to pass through are formed on both the elastic protective sleeve 6 and the trampoline pad 5 .
  • This embodiment is different from the embodiment 1 in that: the edge of one end of the elastic protective sleeve 6 located at the bottom of the trampoline frame 1 is tied tightly through an elastic belt connected to the periphery of the elastic protective sleeve 6 .
  • the trampoline frame 1 is square.
