a) Field of the Disclosure
The invention relates to a structure for quickly clipping an advertising curtain, and more particularly, to a concept of combination of a first frame and a second frame for forming a guide-groove space and a clipping space, wherein a fastener includes a compressible portion with two ends abutting against sidewalls of the guide-groove space formed by the first and second frames such that the first and second frames can firmly join due to the guide-groove space being pushed to expand.
b) Brief Description of the Related Art
With regards to a medium or large type of advertising curtains, huge, shock and eye-catching makers in a long distance can be provided, and moreover, advertisement can be impressed particularly in a playground, in an exhibition hall, on a building curtain or on an external wall of a huge building. The advertising curtains are the enterprise and the consortium's most favorite way to advertise, and can be focused on by consumers. Currently, the medium or large type of advertising curtains have been developing well and become key business advertising practitioners focus on developing. However, referring to
With regards to the medium or large type of advertising curtains, the process to pull, expand or fasten the advertising curtain C using the ropes C1 to tie the advertising curtain C on the frame groove B in the frame A is time-consuming. The way to tie the ropes C1 is concerned with the durability of the tying between the advertising curtain C and the ropes C1. However, when the advertising curtain C is impacted by wind forces in different directions, the whole sheet of the advertising curtain C bears relatively high wind resistance. The instant reaction stress due to the shock or movement of the advertising curtain C causes the ropes C1 and the eye-shaped holes C2 at the periphery of the advertising curtain C to bear high instant stress of wind resistance. The high instant destructive tension or stress would lead the rope C1 or the eye-shaped holes C2 at the periphery of the advertising curtain C to be broken. However, the problems cannot be only solved by the tying fashion of the rope C1. Aerial works are required for follow-up maintenance. This causes the maintenance to be difficult, dangerous and cost-consuming.
In practice, the whole frames A could be bent or deformed and the medium or large type of the advertising curtain could have the skeleton to be damaged or collapsed because the advertising curtain C hardly bears the high instant destructive tension of wind resistance, that is, the wind resistance impacted on a surface of the advertising curtain C, which directly passes to the whole frames A.
In accordance with the present invention, a structure for quickly clipping an advertising curtain includes a first frame, a second frame secured to the first frame so as to form a guide-groove space and a clipping space and at least a fastener arranged in the guide-groove space formed by the first and second frames, wherein the fastener includes a first connecting part and a second connecting part pivoted with the first connecting part, wherein the second connecting part includes a compressible portion laterally extending from two sides thereof at an end of the second connecting part, wherein the compressible portion of the second connecting part has two ends abutting against sidewalls of the guide-groove space formed by the first and second frames such that the first and second frames can be quickly assembled or disassembled due to the guide-groove space being pushed to expand. At the same time, the clipping space formed by the first and second frames can be reduced to firmly clip a sidebar of a predetermined object, such as a sidebar of an advertising curtain, such that the predetermined object can be prevented from dropping from the clipping space.
In accordance with the above structure for quickly clipping the advertising curtain, the combination of the first and second frames and fastener can lead the traditional medium or large type of advertising curtain not to bear point-wise wind resistance, due to the tying of the ropes C1 and the eye-shaped holes C2 at the periphery of the advertising curtain, but to bear linear or planar wind resistance. Thereby, the bearing of the stress of wind resistance can be dispersed and thus the assembly, flatness, construction efficiency, maintenance and the stress of wind resistance can be significantly improved.

The first frame 1 is provided with a first guide groove 12 at a side of the joining groove 11 and a first recessed groove 13 at another side of the joining groove 11. A connecting groove 14 is arranged at another side of the first frame 1.
The second frame 2 is secured to the first frame 1. The second frame 2 includes a joining portion 21 at a side of the second frame 2, wherein the joining portion 21 is correspondent to the joining groove 11 at the first frame 1 and configured to be secured to the first frame 1. The joining portion 21 includes at least a second locking hook 211 configured to be engaged with the first locking hook 111. The second frame 2 is provided with a second guide groove 22 at a side of the joining portion 21 and a second recessed groove 23 at another side of the joining portion 21. The second guide groove 22 at the second frame 2 is correspondent to the first guide groove 12 at the first frame 1 and both form a guide-groove space 10. The second recessed groove 23 at the second frame 2 is correspondent to the first guide groove 13 at the first frame 1 and both form a clipping space 20.
The fastener 2 is embedded in the guide-groove space 10 formed by the first and second frames 1 and 2. The fastener 3 includes a first connecting part 31 and a second connecting part 32. The first connecting part 31 includes a first connecting portion 312 at an end of the first connecting part 31 and a triggering portion 313 at another end of the first connecting part 31. The first connecting part 31 is provided with a securing groove 311 between the first connecting portion 312 and the triggering portion 313. A -shaped elastic element 33 can be embedded in and fixed with the securing groove 311. The triggering portion 313 has a slopped surface 3131 facing the guide-groove space 10. The second connecting part 32 includes a second connecting portion 321 at an end of the second connecting part 32 and a compressible portion 322 laterally or horizontally extending from two sides thereof at an end of the second connecting part 32 far away from the second connecting portion 321. Thereby, the compressible portion 322 and the second connecting part 32 construct a T-shaped structure. The compressible portion 322 includes elastomer 34 at two ends of the compressible portion 322. The second connecting part 32 includes at least a bump 323 protruding from a surface of the second connecting part 32 far away from a surface of the guide-groove space 10.

Besides, the fastener 3 is secured in the guide-groove space 10 formed by the first and second frames 1 and 2. The compressible portion 322 of the second connecting part 32 of the fastener 3 can be previously arranged in the guide-groove space 10. The elastomer 34 at two ends of the compressible portion 322 can be compressed to be elastically deformed such that the two ends, i.e. elastomer 34, of the compressible portion 322 of the fastener 3 can abut against sidewalls of the guide-groove space 10 formed by the first and second frames 1 and 2 such that the guide-groove space 10 formed by the first and second frames 1 and 2 can be pushed to expand and the joining portion 21 can be tightly secured to the joining groove 11, as shown in -shaped elastic element 33 can serve as a stop mechanism to stop the first connecting part 31 freely dropping from the guide-groove space 10, as shown in
When the guide-groove space 10 formed by the first and second frames 1 and 2 is pushed to expand, the clipping space 20 formed by the first and second frames 1 and 2 is reduced to firmly clip a predetermined object 4, such as an advertising curtain, as shown in
When the first and second frames 2 are being detached, the triggering portion 313 of the first connecting part 31 of the fastener 3 can be moved such that the first connecting part 31 can be moved from the guide-groove space 10 and then the compressible portion 322 of the second connecting part 32 of the fastener 3 can be released from the sidewalls of the guide-groove space 10 formed by the first and second frames 1 and 2. Thereby, the second connecting part 32 can be moved from the guide-groove space 10 and the joining portion 21 can be released from the joining groove 11. Accordingly, the first and second frames 1 and 2 can be quickly assembled and disassembled.
When the compressible portion 322 of the second connecting part 32 of the fastener 3 is arranged in the guide-groove space 10, the blocking of the bump 323 can lead the fastener 3 to bend in only one direction. Accordingly, a foolproof way for the assembly or disassembly can be achieved. The slopped surface 3131 of the triggering portion 313 of the fastener 3 can be ensured to get far away from a surface of the guide-groove space 10. Thereby, a user can easily move or lift the triggering portion 313, as shown in
