Structure of a side rail of an advertising panel

Abstract

An improved structure of a side rail of an advertising panel includes a framework having four liftable side rails and four corner pedestals for connecting with these four side rails, and the corner pedestal is hollow and the L-shaped side of the corner pedestal is an opening. With this arrangements, these corner pedestals of the advertising panel are possible simply by lifting these side rails easily to change an advertising board fast and the latter is therefore more convenient for use to lift.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a design of a corner pedestal for an advertising panel, and more particularly to a design of a corner pedestal that enables a fast changing of simply with easy open and close side rails of an advertising panel.

[0002] In the rapidly developed industrial and commercial society, the traders have to decorate their product or put an advertisement in an advertising medium in order to sell their product smoothly. Although there are many kinds of advertising media, the best way to catch people's attention in t he darkness is the advertising panel. The structure of advertising panel and its translucent board used to be very heavy. Now they have improved to be a light and thin structure. In order to replace the conventional structure of the advertising panel, the translucent board of the advertising panel in various models are to some extent made light. Further, for the varied development of society, the traders have to change a new advertisement in time for receiving of full attention. Therefore, the advertisement board of the advertising panel should be easy to change and be pleasing to the eye. The advertising panel is popular because of changeability. However, the conventional structure of the advertising panel has a lot of trouble to change its advertisement board.

[0003] Taiwan Patent Publication No.356275 discloses a conventional structure of an advertising panel. FIG. 3 is sectional view illustrating the conventional structure of the advertising panel.

[0004] FIG. 4 is a partial enlarges view illustrating the conventional structure of the advertising panel. As shown in FIGS. 3 and 4, the advertising panel includes a framework 10 arranged a plate at both the front and rear end of the framework 10, and a light-guided board of a luminous body is installed between the front plate and the rear plate. The framework 10 is composed of several side rails 101 and a corner pedestal 102. The side rails 101 are further composed of a front side rail 1011 and a rear side rail 1012. A slot plate 10111 is formed on one side of the front side rail 1011. Several through holes 10112 are arranged in the slot plate 10111. A groove 10113 is formed on another side of the front side rail 1011. A front end of the groove 10113 is extending to the plate surface. A batten 103 having an inserted portion is tightly inserted into the groove 10113. An internal plate 10121 is formed on one side of the rear side rail 1012. A row of groove 10122 is fully arranged in the internal plate 10121. A fixed groove 10123 is formed on a flange of the internal plate 10121. The front side rail 1011 is connected with the rear side rail 1012 and the slot plate 10111 is inserted into the fixed groove 10123 of the rear side rail 1012. The groove 10122 of the rear side rail 1012 is screwed to lock into the through hole 10112 of the front side rail 1011 by using a screw 104. A joint flange portion 10124 is formed in the inner side of the internal plate 10121 of the rear side rail 1012. A connecting pipe 1021 is formed at both side of a right angle framework 102. A positional groove 1022 formed in the connecting pipe 1021 is then tightly inserted into the joint flange portion 10124.

[0005] In the above described prior art, a screw 104 needed to be unloaded before dismounting or mounting the board, and then separate the front side rail 1011 and the rear side rail 1012 for implementing the change of the board. After the change of the board is completed, the batten 103 is stuffed into the groove 10113 of the front side rail 1011 again for fixing the board tightly. The change of the board wastes a lot of time. If there are numbers of the required change of the board, it goes without saying that the cost of operation will be increased.

[0006] Moreover, please refer to FIGS. 5 and 6 illustrating another embodiment of the conventional advertising side rail. As shown in FIGS. 5 and 6, the advertising panel includes a framework 20 which can be lifted. A deforming elastic segment, not shown, is installed between a side rail 20 and a cover plate 201 to control the opening and closing of the cover plate 201. However, because the two end portions of the cover plate 201 is assumed a dip angle to connect with each other, the dip angle of the end portions will get stuck and against each other when the cover plate is opened for changing the advertising board. Therefore, the angle of opening the cover plate 201 will be reduced substantially and it will be inconvenient for workers to exchange and draw out the advertising board.

[0007] In brief, the conventional advertising panel does not solve the problem of changing an advertising board conveniently. It is therefore desirable to develop a design of a corner pedestal for an advertising panel which is capable of opening and closing its side rail easily.

SUMMARY OF THE INVENTION

[0008] A primary object of the present invention is to provide an improved structure of a corner pedestal that enables a fast changing of simply with an easy open and close side rail of an advertising panel.

[0009] To achieve the above and other objects, an advertising panel of the present invention mainly includes a framework having four liftable side rails and four corner pedestals. These side rails can be lifted easily and be connected to these corner pedestals. The corner pedestal is hollow in its internal part and the L-shaped side of the corner pedestal is an opening which is used for connecting to these corner pedestals. With the above arrangements, a corner pedestal of an advertising panel is possible simply by lifting these side rails easily to change an advertising board fast.

DETAIL DESCRIPTION OF THE REFERRED EMBODIMENTS

[0017] Please refer to FIG. 1 and FIG. 2 that shows a corner pedestal of an advertising panel in an assembled state and a preferred embodiment of the present invention respectively. As shown, an advertising panel includes a framework having four side rails 1 and four corner pedestals 2, which is use for connecting to the corner pedestal 2.

[0018] The side rail 1 is connected to a cover plate 12 from an outer side of a U-shaped base 11. A deforming elastic segment 13 is installed between the base 11 and the cover plate 12 to control for opening and closing the cover plate 12. The two inner side of the side rail respectively extending to lean against the plate surface may be used to clip various required board from both sides. Two lock holes 121 are provided on the two side of the base 11.

[0019] The corner pedestal 2 like a rectangular figure is hollow in its internal part and the L-shaped side of the corner pedestal is an opening 21. A lock plate 22 is formed from the two adjacent ends of the extending of the opening 21. A lock hole 221 is provided on the lock plate 22 corresponding to the lock hole 121 of the base 11 and a screw 3 is locked the side rail 1 and the corner pedestal 2 to connect the end of the two side rails 1. A block slice 23 correspondingly formed from the two adjacent tops of the opening 21 is provided to make the cover plate 12 to stride against it.

[0020] In this manner, when the cover plate 12 is lifted upward, the end portions of the side rails will not get stuck and against each other. In the meantime, the advertising board will be also clipped and buckled by the inward right angle of corner pedestal 2 and the clipping power of the cover plate 12. This is showed a great effect for fixing the advertising board. With the above-described arrangements, a corner pedestal of an advertising panel is possible simply by lifting these side rails easily to change an advertising board fast and the latter is therefore more convenient for use.
