Detailed Description

The present invention is described in detail and technical content with reference to the accompanying drawings, wherein:

referring to fig. 1 to 4, the present invention provides a trampoline support 100, the trampoline support 100 is implemented by matching at least one elastic member 50 and a trampoline fabric 60 to form a trampoline 70, and the trampoline fabric 60 is disposed in the trampoline support 100 through the elastic members 50. Specifically, the trampoline support 100 includes a frame 10 and a plurality of support legs 20, the frame 10 includes a plurality of support tubes 11 assembled in sequence and a plurality of connection posts 12 respectively disposed on one of the support tubes 11, the support tubes 11 are assembled to form a ring or polygonal shape, and the shape of the frame 10 is not limited to the drawing. Moreover, the support tubes 11 may be identical, and each of the connecting columns 12 is disposed on one of the support tubes 11, and further, at least one connecting column 12 may be disposed on each of the support tubes 11, which is not limited to a single one. When the support pipes 11 are not assembled, the connecting columns 12 are already disposed on the support pipes 11, that is, each support pipe 11 and at least one connecting column 12 can form a part. Furthermore, when the support pipes 11 are assembled, a frame space 13 is defined, and the jumping bed cloth 60 is disposed in the frame space 13. In addition, the connecting columns 12 are spaced apart, and the distance between two adjacent connecting columns 12 can be equal.

Referring to fig. 1 to 9, each of the support legs 20 is respectively assembled with one of the connecting columns 12, and further, in order to enable the support legs 20 to perform a pivoting stroke 80 with respect to the frame 10, each of the connecting columns 12 is provided with an installation gap 121 for providing one of the support legs 20, and each of the support legs 20 has a bridging member 21 disposed in the installation gap 121 and pivotally connected to the connecting column 12, an operating sleeve 22 sleeved on the bridging member 21, a spring 23 disposed in the operating sleeve 22, and a column foot 24 penetrating into the operating sleeve 22 and assembled with the bridging member 21. More specifically, the bridge 21 includes a mounting piece 211 disposed in the mounting gap 121 and a supporting block 212 connected to the mounting piece 211, the mounting piece 211 is configured to correspond to the mounting gap 121, and the bridge 21 is pivotally connected to the connecting column 12 via the mounting piece 211. Also, the inner diameter of the operation sleeve 22 is set to be identical to or slightly larger than the column base 24. Further, the operating sleeve 22 has a limiting ring 221 disposed inside the operating sleeve 22, and one end of the spring 23 is pressed against the limiting ring 221 when assembled. In addition, the column foot 24 of the present invention is assembled with the bridge member 21, in one embodiment, the bridge member 21 has a first screw thread 213 disposed on a side of the support block 212 away from the mounting plate 211, and the column foot 24 has a mounting opening 241 allowing the support block 212 to be inserted therein and a second screw thread 242 disposed on the mounting opening 241 and assembled with the first screw thread 213. Furthermore, in order to limit the spring 23, the pillar 24 further has a stopping portion 243, the stopping portion 243 is provided to support the spring 23 thereon, the stopping portion 243 can be formed by a change in the caliber of the pillar 24, for example, the pillar 24 and the bridge 21 are implemented by a caliber, the rest of the pillar 24 is implemented by another caliber larger than the caliber, and the stopping portion 243 is formed at the caliber change. In addition, the stopping portion 243 can also be formed by a convex ring or a bump on the column base 24.

In this embodiment, the spring 23 may be a compression spring. After the assembly of the spring 23, it is restrained by the pedestal 24 and abuts against the operating sleeve 22. That is, the spring 23 of the present invention has a first end 231 pressed by the restraining ring 221 and a second end 232 restrained by the column foot 24. Furthermore, the spring 23 is compressed by the displacement of the restraining ring 221 when the operating sleeve 22 is forced to displace along the column foot 24, and when the operating sleeve 22 is not forced, the spring 23 returns to its original shape so that the operating sleeve 22 is pushed toward the connecting column 12. Accordingly, the operating sleeve 22 of the present invention has a first state supported by the spring 23 and abutting against the connecting column 12 and a second state forced to compress the spring 23 and disengage from the connecting column 12. Referring to fig. 7 and 8, the first state refers to the operating sleeve 22 being unstressed, and the second state refers to the operating sleeve 22 being stressed. Further, when the operating sleeve 22 is in the first state, the operating sleeve 22 is pushed by the spring 23, and a part of the structure is sleeved on the connecting column 12, so that the supporting leg 20 cannot pivot relative to the connecting column 12 by the bridging member 21. That is, when the operating sleeve 22 is in the first state, the supporting foot 20 is restricted from rotating. On the other hand, when the operating sleeve 22 is in the second state, the operating sleeve 22 has been displaced, and the limitation on the bridge 21 is released, so that the bridge 21 can perform the pivot stroke 80 with respect to the connecting column 12, i.e., the supporting foot 20 can rotate with respect to the frame 10. In view of the above, the operating sleeve 22 is pushed by the spring 23, so that when the operating sleeve 22 enters the second state, once the operating sleeve 22 is not continuously subjected to the force of displacing toward the column foot 24, the operating sleeve 22 loses the force of compressing the spring 23, the spring 23 returns to its original shape, and the spring 23 drives the operating sleeve 22 to displace toward the connecting column 12 when returning.

Referring to fig. 1 to 3, the use of the trampoline support 100 is described herein, and it should be noted that the trampoline 70 is formed by the trampoline support 100, the trampoline cloth 60 and the elastic members 50, and the supporting legs 20 are used for supporting as an initial state. In the initial situation, the trampoline 70 can be used normally. The operating sleeve 22 of each of the support legs 20 is not stressed and is in the first state for a long time, and each of the support legs 20 cannot be bent. When the user finishes using the trampoline 70, the user can operate the supporting legs 20 one by one, so that the operating sleeve 22 on each supporting leg 20 is firstly switched from the first state to the second state, and then the supporting leg 20 is made to perform the pivoting stroke 80, so that the supporting leg 20 is bent towards the frame space 13, and the continuous state is as shown in fig. 2 and 3. Furthermore, after the supporting foot 20 is bent, the user can stop applying force to the operating sleeve 22, and when the operating sleeve 22 stops applying force, the spring 23 pushes the operating sleeve 22 to move toward the connecting column 12, so that the operating sleeve 22 pushes against the side edge of the connecting column 12 to limit the supporting foot 20 to rotate. That is, after the bending of each of the supporting legs 20 is completed, the supporting legs cannot move freely. In this way, the trampoline 70 can be stored in a small volume. Furthermore, when the user wants to use the stored trampoline 70, the user only needs to operate the supporting legs 20 one by one again to apply a force to the operating sleeve 22 on the supporting legs 20 away from the connecting column 12, so that the operating sleeve 22 enters the second state, and then the supporting legs 20 can move through the pivoting stroke 80 until the supporting legs 20 return to the state capable of supporting the trampoline 70. Thereafter, once the operating sleeve 22 stops being stressed, the operating sleeve 22 will return to the first state, and the support foot 20 is prohibited from bending.

In view of the above, the trampoline 70 of the present invention can be stored in a small volume by the aforementioned components. In addition, the spring 23 of the present invention is configured differently from the conventional structure, in which an elastic component is conventionally disposed in a leg, one end of the elastic component is disposed on the trampoline frame, and the other end of the elastic component is disposed at the bottom of the space in the leg, and when the storage is performed, the leg needs to be pulled apart by a significant distance from the trampoline frame to perform the storage operation. Conversely, the operating sleeve 22 is matched with the spring 23 for use, and the spring 23 does not need to bear severe deformation in the using process, so that the service life of the spring 23 is further ensured, and the phenomenon that the spring 23 is failed too fast to damage the reputation of developers is avoided. Furthermore, the conventional structure requires a user to apply a large force to deform the elastic member to a degree that the leg can be bent, but the present invention can be completed only by switching the state of the operating sleeve 22, so that the user can easily perform the operation.

Referring to fig. 4 to 6, fig. 6 is a schematic cross-sectional view taken along line a-a of fig. 5. To increase the structural stability of the operating sleeve 22 against the connecting column 12, in one embodiment, each connecting column 12 has a first portion 122 connected to one of the support tubes 11 and a second portion 123 extending from the first portion 122 in a direction away from the support tube 11. Further, each connecting column 12 further has a first width 124 corresponding to the first portion 122 and a second width 125 corresponding to the second portion 123, and the second width 125 is smaller than the first width 124, i.e. the connecting column 12 is formed in a step-like shape in the present embodiment. The second width 125 is at least equal to the inner diameter of the operating sleeve 22, i.e. the second portion 122 of the connecting rod 12 is located in the operating sleeve 22 when the operating sleeve 22 is in the first state, and the top edge of the operating sleeve 22 is against the connection between the first portion 122 and the second portion 123. In addition, to increase the area of the operating sleeve 22 that can be pressed against the connecting column 12, in one embodiment, the connecting column 12 has a collar 126 disposed between the first portion 122 and the second portion 123.

Referring to fig. 4 to 7, in one embodiment, each connecting column 12 may be formed by two mounting walls 127 spaced apart from each other to define the mounting gap 121 and a connecting block 128 connecting the two mounting walls 127. Further, the two mounting walls 127 may be identical in configuration to avoid the problem of different structures on the left and right sides. Furthermore, each connecting column 12 of the present embodiment can be integrally formed or assembled by multiple components to form the aforementioned structure according to the implementation requirement.

Referring to fig. 4-7, in one embodiment, the connecting column 12 has a first surface 129 facing the bridge 21, and the first surface 129 can refer to a surface of the connecting column 12 on a side away from the support tube 11. The mounting piece 211 of each bridge 21 is only disposed on the portion of the supporting block 212, and the portion of the supporting block 212 not connected to the mounting piece 211 is formed with a second surface 214. When the operating sleeve 22 is in the first state, the second surface 214 faces the first surface 129, and even more the second surface 214 can contact the first surface 129. Moreover, the first surface 129 and the second surface 214 can be an arc surface respectively, and when the first surface 129 is a convex arc surface, the second surface 214 is a concave arc surface, that is, the first surface 129 and the second surface 214 correspond to each other. Referring back to fig. 7, in order to increase the stability of the pivotal movement 80 of the supporting legs 20 driven by each of the bridging members 21, in another embodiment, the mounting plate 211 has a pivot portion 215 originally assembled with the two mounting walls 127, and further has a structural reinforcing portion 216 extending from the pivot portion 215, so that the contact area between the mounting plate 211 and each of the mounting walls 127 is changed to the area of the pivot portion 215 contacting the mounting wall 127 plus the area of the structural reinforcing portion 216 contacting the mounting wall 127.

In one embodiment, each connecting column 12 is composed of a housing 130 and an inner container 131 disposed in the housing 130, the housing 130 and the inner container 131 can be made of different materials, for example, the housing 130 and the supporting tube 11 can be made of metal, and the inner container 131 can be made of plastic. Accordingly, the outer shell 130 can be welded to the support tube 11, and the inner container 131 can be inserted into the outer shell 130. Also, the housing 130 has an opening 132 corresponding to the mounting gap 121, and further, the housing 130 may be formed in a U-shape, and the cut-away portion is the opening 132. Furthermore, the connecting column 12 has at least one first connection hole 133 connected to the mounting gap 121, the bridge 21 has a second connection hole 217 corresponding to the first connection hole 133, the housing 130 has a third connection hole 134 corresponding to the first connection hole 133, the second connection hole 217 and the third connection hole 134 are identical in shape, and a connecting member 90 is allowed to pass through the third connection hole 134, the first connection hole 133 and the second connection hole 217 sequentially to generate a pivot connection during assembly.
