Description

Trampoline and safety buckle structure thereof

Technical Field

The invention relates to the technical field of trampolines, in particular to a trampoline and a safety buckle structure thereof.

Background

Trampoline sports is a healthy and interesting recreational activity. Research shows that trampoline sports not only can exercise body and strengthen muscle strength, but also can help people develop balance and improve motor skills. Chinese invention patent CN1607807A filed by international company for wood boards and battens discloses a soft-edge trampoline comprising a flexible mat (1) supported in a base frame (3) by a plurality of resiliently flexible rods (2). Each rod (2) has an enlarged upper end (3). A plurality of fittings (6) are joined to the mat (1) around the periphery of the mat, each fitting (6) having a socket cavity (10), the socket cavity (10) receiving an enlarged upper end (12) of a flexible rod so that the upper ends of the flexible rods are pivotally connected to the periphery of the mat. This patent provides a series of advantages in connecting the major ends of the rods to the periphery of the mat by means of a socket having a cavity on the underside of the socket and an enlarged upper end of the rod (and vice versa). The ends of the rods are encased which significantly reduces the likelihood of injury to a user falling at the edge of the trampoline. A more secure engagement can be achieved between the ends of the rods and the mat so that the rods remain more securely connected when the trampoline is in use. And this connection allows easy assembly and disassembly of the rod-spring with the edge of the mattress. Trampolines are usually shipped to the purchaser in disassembled form and it is important that the purchaser be able to assemble the trampoline from the discrete components without difficulty.

However, in order to support the mat and the person moving on the mat, the flexible rods must have a certain bending stiffness. For example, in another Chinese patent CN101102821B, plank & Batten International discloses that the flexural rigidity of a flexible rod is 1200N/m to 3000N/m. In fact, this bending stiffness is a common bending stiffness for trampoline common flexible rods. It is difficult in practice for the purchaser to pull the enlarged upper end (3) of the flexible rod into the socket cavity (10) of the connector (6) with the bottom end of the flexible rod secured in the base frame (3), requiring a great deal of effort.

On the other hand, the enlarged upper end (3) of the flexible rod is mounted in the socket cavity (10) of the connector (6) and when the pressure carried by the flexible rod exceeds a certain range, the flexible rod bends to a certain extent, and the upper end (3) may fall out of the socket cavity (10), thereby damaging the trampoline and causing accidents to the trampoline sporter.

Furthermore, the engagement of a plurality of fittings (6) at the periphery of the mat (1) also adds to the components of the trampoline and increases the production costs.

Therefore, there is a need for an improved combination of a trampoline flexible rod and a trampoline mat that provides a more secure combination of a flexible rod and a mat that is easy and convenient to install.

Referring to fig. 1 and 2, a plurality of safety snap structures 70 are arranged on the periphery of the mat 10, the safety snap structures 70 correspond to the flexible rods 30 one by one, and the top 31 of the flexible member 30 is detachably mounted at a predetermined position at the bottom of the periphery of the mat 10, so that the mounting manner is labor-saving and convenient. Referring to fig. 3, the safety catch structure 70 includes a mounting member 71, a flexible band 72, and at least one catch 73 fixedly provided on the flexible band 72. The flexible belt 72 is fixedly arranged at the bottom of the cushion 10, the mounting member 71 is provided with a through hole 723, the retainer 73 and the belt 72 can pass through the through hole 723, after passing through, the retainer 73 is rotated to be fixedly retained at the opening of the through hole 723, and the belt 72 is prevented from being pulled back from the through hole 723 under the action of a pulling force; the top of the flexible rods 30 are received in the mounting member 71 to mount the top 31 of the flexible member 30 to the mat 10 at a predetermined position.

Preferably, referring to fig. 3, in one embodiment of the present invention, the mounting member 72 is provided at a bottom thereof with a receiving groove (not shown) in which the top 31 of the flexible rod 30 is fixedly disposed. Preferably, the receiving groove is provided in the extending direction of the top 31 of the flexible rod, so as to facilitate the insertion and matching of the top 31 of the flexible rod 31. In the embodiment shown in fig. 3, the mounting member 72 is cube-like in shape. It should be understood that the profile of the mounting member 72 is not limited to the shape shown in the figure, and may be spherical, polyhedral or any other shape. The present invention does not specifically limit the external shape of the mounting member 72, and any variation in the external shape of the mounting member 72 without departing from the basic concept of the present invention should be considered as falling within the scope and spirit of the present invention.

Preferably, referring to fig. 4, 5 and 7, the mounting member 72 has a narrow tube portion 721 and an enlarged head portion 722 disposed at the tip of the narrow tube portion 721. The tip 31 of the flexible rod 30 is inserted into the narrow tube part 721 and fixedly connected thereto. The narrow tube part 721 is provided in the extending direction of the tip part 31 of the flexible rod so as to facilitate the insertion and matching of the tip part 31 of the flexible rod 31. The head 722 is provided with the through hole 723 in a lateral direction.

Referring to fig. 4, the head portion 722 has a larger lateral diameter than the narrow tube portion 721, so that the contact area of the mounting member 71 with the mat 10 is increased, and the mat 10 is more stably supported.

Preferably, an abutment plate 724 projects from the head 722 at the outlet of the through hole 723. The blocking piece 724 can block the retainer 73, so as to prevent the retainer 73 from sliding and retracting into the through hole 723.

Specifically, referring to fig. 4, the head portion 721 is shaped like a rectangular parallelepiped, and the bottom surface of the head portion is integrally formed with the narrow tube portion 721, and the side of the narrow tube portion provided with the through hole 723 is arranged with a large end and a small end, and is tapered from the large end to the small end. The through-hole 723 is provided in a flat hole. The strap 72 and the retainer 73 are both in a sheet shape so as to be capable of passing through the through hole 723 in cooperation with the through hole. After passing through the through hole 723, the retainer 73 is rotated at a certain angle to be retained at the orifice of the through hole 723.

The retainer 73 can pass through one side of the through hole 713 and be retained at the other side opening of the through hole 713. In the embodiment of the present invention, the retainer 73 has a smaller short side and a longer long side. The short side of the retainer 73 is slightly smaller than the hole width of the through hole 713, and the long side of the retainer 73 is slightly larger than the hole width of the through hole 713. Such a structural arrangement enables the retainer 73 to pass from one side to the other side of the through hole 713, and rotates the retainer 73 after passing through to retain it at the orifice of the through hole 713.

It should be understood that the catch 73 matches the shape of the through hole 713. For example, when the retainer 73 is provided in an elongated cylindrical shape, the through hole 713 should also be provided in an elongated cylindrical shape; when the retainer 73 is formed in a long cube shape, the through hole 713 must be correspondingly formed in a long cube shape. Referring to fig. 3 and 4, in the preferred embodiment of the present invention, the retainer 73 is provided as a long cubic thin metal card. The through hole 713 is also provided as an elongated cuboid flat. Preferably, the holding member 73 of the present invention is formed in a shape of a Chinese character 'ri'. Preferentially, the tail part of the clamping piece in the shape of the Chinese character 'ri' is provided with a hook.

After the retainer 73 passes through the through hole 713, the retainer 73 is retained at the other side hole of the through hole 713 in the long diameter direction, so that the strap 72 is fixed, and the strap 72 is prevented from retracting under the pulling force, so that the top end of the flexible rod 30 is retained at the predetermined position of the bottom of the periphery of the cushion 10.

It will be appreciated that the position of the retaining members 73 on the straps 72 must be sufficient for the purpose of "mounting the top ends of the flexible rods 30 at predetermined locations around the perimeter of the mat 10". Therefore, it is appropriate that the retainer 73 is mounted on the belt 72. The catch 73 is too far from or too close to the mat 10 to accomplish this design objective.

The straps 72 are fixedly disposed on the mat 10. It should be understood that the flexible straps 72 may be secured to the bottom of the mat 10 in a variety of ways, such as by conventional strap securing means, such as welding, snapping, clasping, and the like. In the preferred embodiment of the present invention, the flexible straps 72 are stitched to the bottom of the mat.

The mounting member 72 may be disposed directly on top of the flexible rod 30. During the installation process, the bottom ends 32 of the flexible rods 30 are fixed on the supporting seat tube 20, the straps 72 are threaded through the through holes 723, the top portions 31 of the flexible rods 30 and the mounting members 72 are pushed to the predetermined positions of the periphery of the cushion 10, the retainers 73 are pulled out of the through holes 723, and the retainers 73 are rotated to be retained at the through holes 723, so that the top portions 31 of the flexible rods 30 and the head portions 722 are installed at the bottom of the periphery of the cushion 10.

The mounting member 72 may be directly threaded on the strap 71. In the installation process, the bottom ends 32 of the flexible rods 30 are firstly fixed on the supporting seat tube 20, the mounting member 72 is adjusted to the proper position of the strap 71, the top parts 31 of the flexible rods 30 are inserted into the mounting grooves or the thin tube parts of the mounting member 72, the top parts 31 of the flexible rods 30 and the mounting member 72 are pushed to the preset position of the periphery of the cushion 10, the holding members 73 are pulled out from the through holes 723, and the holding members 73 are rotated to be held at the through holes 723, so that the purpose of installing the top parts 31 and the head parts 722 of the flexible rods 30 at the bottom of the periphery of the cushion 10 is achieved.

In the trampoline structure, a plurality of the flexible rods 30 are uniformly distributed at the bottom of the circumference of the saddle pipe 20 and the mat 10, and support the mat 10 such that the force is uniformly applied to the mat 10 in all directions. In the installation process of the trampoline, by adopting the method of sequentially installing the plurality of flexible rods 30, the stress on the mat on one side without the flexible rods 30 is unbalanced, so that the installation difficulty of the flexible rods on the side is increased, and even the forming structure of the final product is affected. To avoid this, referring to fig. 6 and 7, the two catches 73 are provided on the strap 72 of the present invention, with the first catch 73 enabling the top of the flexible rod 30 and the head 722 to be mounted in a pre-installed position, e.g., near the perimeter of the mattress 10. The second catch 73 enables the top of the flexible rod 30 and the head 722 to be mounted in an installed position, i.e., around the perimeter of the mat 10. In the mounting process, the bottom end of the flexible rod 30 is fixed to the seat tube 20, the strap 72 is pulled so that the first retainer 73 passes through the through hole 713 of the head, and the retainer 73 is retained at the through hole 713 in the long-diameter direction. At this point, the flexible rod 30 top and the head are mounted in a pre-mounted position, such as: the periphery of the mat. After all the tops of the flexible rods 30 are mounted at the pre-installation position, the straps 72 are sequentially pulled such that the second catches 73 pass through the through holes 723 and are caught at the through holes 723 in the major-diameter direction, the flexible rods 30 are further bent, and the tops of the flexible rods 30 are mounted at the installation position, i.e., the periphery of the mat 10.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the present invention pertains, the architecture form can be flexible and varied without departing from the concept of the present invention, and a series of products can be derived. But rather a number of simple derivations or substitutions are made which are to be considered as falling within the scope of the invention as defined by the appended claims.
