Description

Technical Field

[0001] The present invention relates to the technical field of trampolines, in particular to a trampoline frame and a trampoline having the trampoline frame. Background Art

[0002] Trampoline exercise is a healthy and interesting recreational activity. Studies have shown that trampoline exercise can not only exercise the body and enhance muscle strength, but also help people develop a sense of balance and improve sports skills. With the development of technology, trampolines are increasingly entering people's lives. The basic structure of a trampoline includes a jumping mat, a frame, a plurality of flexible rods, support legs, a protective net and a support rod. The top end of the flexible rod is installed around the jumping mat, and the bottom end of the flexible rod is installed on the frame, so that the jumping mat is erected above the frame. The frame is supported by the support legs and is erected above the ground. The protective net is arranged around the jumping mat and extends above the jumping mat to form a closed or semi-closed jumping space. The protective net protects people exercising on the jumping mat and prevents them from falling off the jumping mat. The support rod is arranged around the jumping mat to open the protective net.

[0003] Most of the existing trampoline frames are made of multiple straight tubes and / or arc-shaped tubes, and the connection between the two tubes is welded, screwed or connected by a connector. For example, Chinese utility model patent CN201721278304.X discloses a trampoline frame connector, and the trampoline frame has a frame connector connected to a first horizontal member. The frame connector is also connected to a second horizontal member. A trampoline leg includes a vertical leg member connected to a horizontal leg member. The trampoline leg is connected to the frame connector. A frame connector large tube extends downward to a frame connector small tube. The frame connector large tube is transformed into a frame connector small tube at the contraction of the frame connector.

[0004] The existing trampoline frame has the following defects:

[0005] 1. The trampoline frame cannot be adjusted in size and cannot meet the requirements of different users at the same time.

[0006] 2. It requires professional installation and is difficult to install;

[0007] 3. It is not convenient to install flexible rods on the trampoline frame connector, and the flexible rods are unevenly distributed, which affects the elasticity of the trampoline mat.

[0008] 4. During the jumping process, the trampoline tubes will rotate relative to each other, producing a harsh friction sound. Summary of the invention

[0009] The present invention provides a trampoline frame and a trampoline having the same, which overcome the above-mentioned defects of the existing trampoline frame, are convenient to disassemble and assemble, and can flexibly adjust the size of the trampoline.

[0010] The technical solution of the present invention is as follows: a trampoline frame, which is formed by connecting and enclosing a plurality of frame tubes, and adjacent frame tubes are connected by a frame connector; the frame connector is a T-shaped tube composed of a horizontal tube and a vertical tube; the outer diameter of the horizontal tube is slightly smaller than the inner diameter of the frame tube; the two ends of the horizontal tube are inserted into the adjacent frame tubes, thereby connecting to form a closed trampoline frame; a plurality of upper frame holes and lower frame holes are arranged in pairs at equal intervals on the top and bottom of the frame tube, and the paired upper frame holes and the lower frame holes are staggered; a plurality of upper plug holes and lower plug holes are arranged in pairs at equal intervals on the top and bottom of the horizontal tube, and the paired upper plug holes and the lower plug holes are staggered; after the two ends of the horizontal tube are inserted into the adjacent frame tubes, each of the upper plug holes coincides with a corresponding upper frame hole, and each of the lower plug holes coincides with a corresponding lower frame hole.

[0011] One end of the frame connector is fixedly connected to the frame tube.

[0012] A connecting pipe is fixedly connected between two adjacent vertical pipes.

[0013] The horizontal tube and the vertical tube are integrally formed, or connected by welding, riveting or screwing.

[0014] The trampoline frame is circular or approximately circular, and is formed by connecting and enclosing a plurality of arc-shaped frame tubes.

[0015] The trampoline frame is approximately oriented or rectangular, and is formed by connecting and enclosing a plurality of straight frame tubes and four arc-shaped frame tubes.

[0016] A notch is provided on the bottom surface of the pipe opening of the frame pipe, and the vertical pipe passes through the notch.

[0017] The adjacent frame connectors are connected through a support frame; the support frame comprises two bent pipes and a horizontal connecting pipe connecting the two bent pipes; the tops of the two bent pipes are inserted into the vertical pipe.

[0018] The frame tube is also provided with a support rod tube, in which a support rod is inserted; and reinforcing ribs are provided between the frame tube and the support rod tube.

[0019] A trampoline comprises the above-mentioned trampoline frame.

[0020] The beneficial effects of the present invention are as follows: the trampoline frame described in the present invention is formed by connecting and enclosing a plurality of frame tubes, and adjacent frame tubes are connected by a frame connector; the frame connector is a T-shaped tube composed of a horizontal tube and a vertical tube; the outer diameter of the horizontal tube is slightly smaller than the inner diameter of the frame tube; the two ends of the horizontal tube are inserted into the adjacent frame tubes to connect into a trampoline frame; a plurality of upper frame holes and lower frame holes are arranged in pairs at equal intervals on the top and bottom of the frame tube, and the paired upper frame holes and the lower frame holes are staggered; a plurality of upper plug holes and lower plug holes are arranged in pairs at equal intervals on the top and bottom of the horizontal tube, and the paired upper plug holes and the lower plug holes are staggered; after the two ends of the horizontal tube are inserted into the adjacent frame tubes, each of the upper plug holes coincides with a corresponding upper frame hole, and each of the lower plug holes coincides with a corresponding lower frame hole. After the flexible rod of the trampoline is inserted into the upper frame hole and the lower frame hole, and the corresponding upper plug hole and the lower plug hole, adjacent frame tubes cannot rotate relative to each other, thereby increasing the stability of the trampoline. When a person jumps on the trampoline, no friction sound caused by the relative rotation of the steel tubes is generated. The trampoline is a silent trampoline that is easy to disassemble and assemble, and the size of the trampoline can be flexibly adjusted, which is worthy of promotion and application.

[0025] In order to make the purpose of the invention, the technical scheme and the technical effect of the present invention more clear, the present invention is further described below in conjunction with specific implementation methods. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The trampoline frame provided by the present invention is formed by connecting and enclosing a plurality of frame tubes 10, and the adjacent frame tubes 10 are connected by a frame connector 20; the frame connector 20 is a T-shaped tube composed of a horizontal tube 21 and a vertical tube 22. The horizontal tube 21 and the vertical tube 22 are integrally formed, or connected by welding, riveting, threaded connection, etc. The outer diameter of the horizontal tube 21 is slightly smaller than the inner diameter of the frame tube 10. The two ends of the horizontal tube 21 are inserted into the adjacent frame tubes 10, thereby connecting to form a closed trampoline frame. When assembling and disassembling the trampoline frame of this structure, it is only necessary to insert or pull out the two ends of the horizontal tube into or out of the adjacent frame tubes 10. The disassembly and assembly are very simple and convenient, and no additional tools and installation skills are required.

[0027] Reference Figure 4 Preferably, the top and bottom of the frame tube 10 are respectively provided with a plurality of upper frame holes 11 and a plurality of lower frame holes 11a in pairs at equal intervals, and each pair of the upper frame holes 11 and the lower frame holes 11a are arranged alternately. Such an arrangement is for the convenience of installing the flexible rod 30 of the trampoline. The flexible rod 30 of the trampoline is inserted obliquely relative to the frame tube 10 into a pair of the staggered upper frame holes 11 and the lower frame holes 11a. Referring to FIG. Figure 3 and Figure 4 , the top and bottom of the horizontal tube 21 are respectively provided with a plurality of upper plug holes 25 and a plurality of lower plug holes 25a in pairs at equal intervals, and each pair of the plug holes 25 and the lower plug holes 25a are staggered; after the two ends of the horizontal tube 21 are inserted into the adjacent frame tubes 10, each of the upper frame holes 11 is overlapped with one of the upper plug holes 25 in a one-to-one correspondence, and each of the lower frame holes 11a is overlapped with one of the lower plug holes 25a in a one-to-one correspondence. At the frame connector 20, the flexible rod 30 is obliquely inserted into a pair of staggered upper frame holes 11 and lower frame holes 11a, and at the same time, the upper plug holes 25 and the lower plug holes 25a that overlap with the pair of upper frame holes 11 and lower frame holes 11a are inserted. This structure fixes the frame connector 20 and the frame tube 10 to prevent the two from rotating relative to each other, thereby increasing the stability of the trampoline.

[0028] Preferably, in one embodiment of the present invention, one end of the frame connector 20 is fixedly connected to the frame tube 10, preferably by welding. This structure prevents the frame connector 20 from rotating relative to the frame tube 10 connected thereto, making the trampoline more stable and avoiding the adjacent tubes from rotating relative to each other and generating friction noise. On the other hand, when installing the trampoline frame, it is only necessary to insert the other end of the frame connector 20 into another adjacent frame tube 10, which simplifies the operation and is convenient.

[0029] In one embodiment of the present invention, the trampoline frame is circular or approximately circular, and is formed by connecting and enclosing a plurality of arc-shaped frame tubes. The outer diameter of the horizontal tube 21 is slightly smaller than the inner diameter of the arc-shaped tube. Both ends of the horizontal tube 21 are inserted into the adjacent arc-shaped tubes, thereby forming a circular or approximately circular frame.

[0030] In one embodiment of the present invention, the trampoline frame is approximately oriented or rectangular, and is formed by connecting and enclosing a plurality of straight frame tubes 10 and four curved frame tubes 10. The inner diameters of the straight frame tubes 10 and the curved frame tubes 10 are the same. The two ends of the horizontal tube 21 are inserted into the adjacent straight frame tubes 10 and the curved frame tubes 10, or the two ends of the horizontal tube 21 are inserted into the adjacent two straight frame tubes 10. Figure 1 The trampoline frame is shown as being approximately square, and the frame tubes 10 at the four corners are all arc-shaped, and each side has a straight frame tube 10. In a trampoline frame approximately in the shape of a rectangular parallelepiped, the frame tubes 10 at the four corners are all arc-shaped, and the two opposite sides have a straight frame tube 10, and the other two opposite sides have at least two pairs of straight frame tubes 10. All the straight frame tubes 10 are of the same specification, thereby reducing mold costs and facilitating production, transportation and assembly. In the trampoline frame, the number of straight frame tubes 10 can be adjusted according to actual needs, thereby adjusting the size of the trampoline to meet the needs of different users.

[0031] A notch 13 is provided on the bottom surface of the pipe opening of the frame pipe 10 , and the vertical pipe 22 passes through the notch 13 , so as to facilitate the installation and removal of the frame connector 20 .

[0032] Adjacent frame connectors 20 are connected by a support frame 40. The support frame 40 includes two curved pipes 41 and a horizontal connecting pipe 42 connecting the two curved pipes 41; the tops of the two curved pipes 41 are inserted into the vertical pipes 22, and the horizontal connecting pipe 42 is placed on the ground, thereby supporting the trampoline frame above the ground.

[0033] A straight connecting pipe 26 is fixedly connected between two adjacent vertical pipes 22. The connecting pipe 26 has the function of strengthening the stability of the connection, thereby making the trampoline frame more stable.

[0034] The frame tube 10 is also provided with a support rod tube 15, and a support rod 50 is inserted into the support rod tube 15. A reinforcing rib 16 is provided between the frame tube 10 and the support rod tube 15 to strengthen the stability of the connection between the two.

[0035] The present invention also provides a trampoline having the above trampoline frame. Since the structure of the trampoline is well known in the prior art and is a well-known technology that should be known to those skilled in the art, this application will not elaborate on it.

[0036] The above content is a further detailed description of the present invention in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, without departing from the concept of the present invention, its architecture can be flexible and can derive a series of products. Just making a few simple deductions or substitutions should be regarded as belonging to the scope of patent protection of the present invention determined by the submitted claims.
