Description

[Technical field]

[0001] The invention relates to the field of sports goods, in particular to a foldable trampoline. [Background technology]

[0002] As we all know, a trampoline is an object that takes up a large space. Therefore, if it is assembled before transportation, it will cause great difficulties in transportation. If it is not assembled but the parts are transported to the customer directly, although the transportation difficulty is reduced, it increases the assembly difficulty for the customer. Therefore, in order to reduce both the assembly difficulty and the transportation difficulty for the customer, the industry has come up with a foldable trampoline.

[0003] Please refer to Chinese Patent No. 201822043842.1, which discloses a foldable trampoline in the prior art. The defect of this foldable trampoline is that only the supporting leg tubes can be folded, but the frame parts cannot be folded. Therefore, the space it occupies is still very large and it is still very inconvenient to transport.

[0004] Please refer to Chinese Patent No. 201620756118.1, which discloses another folding trampoline in the prior art, which can fold the entire frame for multiple times, thereby greatly reducing the difficulty of transportation and the difficulty of assembly for operators. After receiving the goods, customers only need to open the folded frame. However, we found in the actual production process that this type of folding trampoline has safety hazards. When the frame changes from a folded state to an open state, the elastic cloth is stretched. When the frame changes from an open state to a folded state again, the force of the stretched elastic cloth may accidentally act on the operator, causing injury to the operator. In addition, if the trampoline of this structure is slightly larger in size, one operator cannot fold or open the frame, and multiple people are required to operate at the same time. In addition, the tightness of the elastic cloth of the trampoline of this structure cannot be adjusted according to the actual users.

[0005] Therefore, it is necessary to provide a foldable trampoline that solves the above-mentioned technical problems. [Summary of the invention]

[0006] In order to solve the above problems, the object of the present invention is to provide a foldable trampoline with simple structure and convenient installation.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a foldable trampoline, comprising: a frame member, a leg tube, a trampoline and a connecting member, the edge of the trampoline is installed on the frame member through a plurality of connecting members, the leg tube is installed under the frame member, at least one of the trampoline and the connecting member is an elastic member, the frame member comprises a plurality of frame tube sections, and a foldable connection is formed between every two adjacent frame tube sections, the connecting member and the frame member are connected by a plurality of locking mechanisms, the frame member is provided with a plurality of through holes for accommodating the locking mechanisms, each locking mechanism comprises a locking nut and a locking bolt, one of the locking nut and the locking bolt is connected to the connecting member, and the other is abutted against the frame member.

[0008] A foldable trampoline in the present invention is further configured as follows: the connecting piece is an elastic rope, a plurality of buckles are provided on the edge of the jumping cloth, and a through-hole is provided on the locking bolt. The elastic rope passes through the buckles on the edge of the jumping cloth and the through-holes on the locking bolt in sequence to form a serpentine shape between the jumping cloth and the frame.

[0009] A foldable trampoline in the present invention is further configured as follows: the connecting piece is a spring, a plurality of buckles are provided on the edge of the trampoline cloth, a through hole is provided on the locking bolt, one end of the spring is connected to the buckle, and the other end of the spring is connected to the through hole on the locking bolt.

[0011] A foldable trampoline in the present invention is further configured as follows: the perforations are arranged in a circular shape.

[0012] A foldable trampoline in the present invention is further configured as follows: in every two adjacent frame tube sections, one frame tube section is provided with a first connecting member, and the other frame tube section is provided with a second connecting member, and the first connecting member and the second connecting member are connected by a pin or a bolt so that the two frame tube sections form a foldable connection.

[0013] A foldable trampoline in the present invention is further configured as follows: the trampoline cloth and the frame member are both arranged in a circular shape.

[0014] A foldable trampoline in the present invention is further configured as follows: the number of the frame pipe segments is four.

[0015] A foldable trampoline in the present invention is further configured as follows: the leg tubes are threadedly connected to the frame member.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the foldable trampoline of the present invention has an additional locking mechanism compared with the trampoline of the prior art, so that the elastic member in the trampoline is in a taut state only when the trampoline frame is fully opened. During the operation of folding and opening the trampoline, the elastic member is in a relatively loose state, thereby avoiding accidental injury to the operator caused by the elastic member during the folding and opening operation. The tightness of the elastic member of the trampoline of the present invention can be adjusted according to different specific users, and the replacement of the elastic member is also quite convenient.

[Specific implementation method]

[0025] The foldable trampoline of the present invention is further described in detail below through specific embodiments.

[0026] Example 1

[0027] Ginseng Figures 1 to 5As shown, a foldable trampoline includes: a frame member 1, a leg tube 2, a jumping cloth 3 and a connecting member 4, the edge of the jumping cloth 3 is installed on the frame member 1 through the connecting member 4, and the leg tube 2 is installed below the frame member 1. In this embodiment, the jumping cloth 3 and the frame member 1 are both arranged in a circular shape, the jumping cloth is not elastic, the connecting member 4 is an elastic rope, and the leg tube 2 and the frame member 1 are foldably connected. Of course, in other embodiments, the jumping cloth 3 and the frame member 1 can also be other shapes, the jumping cloth 3 is an elastic member, the connecting member 4 is not elastic, or the jumping cloth 3 and the connecting member 4 are both elastic members, all of which can realize the present invention. In other embodiments, the leg tube 2 and the frame member 1 can also be threadedly connected, which can also realize the present invention.

[0028] The frame member 1 includes four frame tube segments 10, and a foldable connection is formed between every two adjacent frame tube segments 10. In the present embodiment, among every two adjacent frame tube segments 10, one of the frame tube segments 10 is provided with a first connecting member 5, and the other frame tube segment 10 is provided with a second connecting member 6. In the present embodiment, the first connecting member 5 and the second connecting member 6 are connected by a pin shaft 7 so that the two frame tube segments 10 form a foldable connection. Of course, in other embodiments, the first connecting member 5 and the second connecting member 6 can also be connected by bolts, which can also realize the present invention.

[0029] The elastic rope is connected to the frame member 1 via a plurality of locking mechanisms 8. The frame member 1 is provided with a plurality of through holes 11 for accommodating the locking mechanisms 8. Each locking mechanism 8 includes a locking nut 80 and a locking bolt 81. One of the locking nut 80 and the locking bolt 81 is connected to the elastic rope, and the other is in contact with the frame member 1. In the present embodiment, a plurality of buckles 30 are provided at the edge of the jump cloth 3, and a circular through-hole 810 is provided on the locking bolt 81. The elastic rope sequentially passes through the buckles 30 at the edge of the jump cloth 3 and the circular through-hole 810 on the locking bolt 81, thereby forming a serpentine shape between the jump cloth 3 and the frame member 1. The locking nut 80 abuts against the outer wall 12 of the frame member 1 or the hole wall of the through-hole of the frame member 1 (not shown). Of course, in other embodiments, circular through-holes may also be provided on the locking nut 80, so that the elastic rope sequentially passes through the buckles 30 at the edge of the jump cloth 3 and the circular through-hole on the locking nut 80, and the locking bolt 81 abuts against the outer wall 12 of the frame member 1 or the hole wall of the through-hole of the frame member 1, thereby realizing the present invention in the same manner.

[0030] The operation process of the foldable trampoline from the folded state to the opened state in the present invention is as follows: first, the trampoline with four frame tube sections 10 folded is opened in the first step. After opening, every two frame tube sections 10 form a semicircular shape, and the entire frame member 1 forms two semicircular shapes. Then, the trampoline opened in the first step is opened in the second step, that is, the two semicircular shapes are opened into a circular shape. During this process, the elastic rope is always in a relatively loose state (that is, the elastic rope is not tightened). After the entire trampoline is fully opened, an L-shaped wrench is inserted into the locking nut 80, and the L-shaped wrench is rotated to rotate the locking nut 80, so that the locking bolt 81 moves toward the end of the locking nut 80. After the operation of several locking mechanisms 8 is completed, the elastic rope is in a tightened state.

[0031] The operation process of the foldable trampoline from the open state to the folded state in the present invention is: first, insert an L-shaped wrench into the locking nut 80, rotate the L-shaped wrench, and the locking nut 80 rotates, so that the locking bolt 81 moves away from the locking nut 80. After the operation of several locking mechanisms 8 is completed, the elastic rope is in a relatively loose state, and then the frame member is folded.

[0032] In summary, the foldable trampoline of the present invention has a locking mechanism added compared to the trampoline in the prior art, so that the elastic member in the trampoline is in a taut state only when the trampoline frame is fully opened. During the folding and opening operation of the trampoline, the elastic rope is in a relatively loose state, thereby avoiding accidental injuries to the operator caused by the elastic rope during the folding and opening operation. The tightness of the elastic rope of the trampoline of the present invention can be adjusted according to the specific users, and the replacement of the elastic rope is also quite convenient.
