OBJECT OF THE INVENTION
[0001] The present invention, as the heading of this specification sets forth, is relate to a device for fastening lamellar bodies to structures or frames, for example billboards or any other similar application.
[0002] There are clearly advantages, especially when mounting and dismounting, which is much faster by avoiding the use of additional hooks, being more environmentally friendly since it is recyclable plastic.
BACKGROUND OF THE INVENTION
[0003] Currently, there are devices for fastening lamellar bodies to structures or frames with beams or strings passing through the buttonholes fixed in the respective lamellar body.
DESCRIPTION OF THE INVENTION
[0004] The device for fastening lamellar bodies is determined from several characteristic buttonholes in principle attached to a lamellar body in proximity to its edges, the buttonholes incorporating radial elongated extensions as flanges to be able to couple and anchor to a billboard structure or other support wherein the respective lamellar body is pretended to be fasten, so that by means of the various elongated extensions of the buttonholes, the lamellar body is anchored to the respective support structure.
[0005] The elongated extensions radially start from the buttonhole allowing its fastening to the structure or frame wherein the corresponding lamellar body is mounted.
[0006] Each radial extension as a flange incorporates in its terminal section a small passageway through which the beginning of this flange is introduced in order to configure a closed ring structure by embracing the bars of the billboard structure and the like, thus securing the anchoring of the lamellar body.
[0007] Other features of the invention are that the radial extension can form an integral part of the buttonhole itself or constitutes an independent element with means to be fixed to the buttonhole body.
[0008] On the other hand, fixing means immovable from the buttonhole to the lamellar body are included wherein a perimeter widening of the buttonholes which is in contact to one of the faces of the lamellar body and a riveting which is in contact to the other partner face of the lamellar body participate, said riveting forming part of a tubular body which joints the perimeter widening and the riveting of such buttonholes.
[0009] In turn, fixing means of the buttonholes to the lamellar body are tightly secured by at least one characteristic jagged which is in contact with at least one of the faces of the lamellar body.
[0010] Next, to facilitate a better understanding of this specification, and being an integral part thereof, figures in which the object of the invention has been represented with an illustrative and not limitative manner are attached.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] Considering the numbering adopted in the figures, the device for fastening lamellar bodies comprises several buttonholes (1) fixed in proximity to the edges of a lamellar body (2), these buttonholes incorporating several radial elongated extensions characteristics as flanges (3) including a smooth terminal section (4) with an narrow passageway (5) by which the beginning of the flange (3) is introduced conforming a close loop structure embracing the bars (6) of a billboard structure (7) or the like, in order to secure the anchoring of this lamellar body (2) to the billboard structure.
[0013] The flange (3) has a jagged (8) to be anchored in a complementary hooking tab (9) located in the mentioned passageway (6) of the smooth initial section (4) of the flange (3), thus securing the anchoring of the lamellar body (2) to the billboard structure (7).
[0014] In a first embodiment (figure 2) the flange (3) forms an integral part of the buttonhole (1), while in a second embodiment (figure 3) the flange (3) comprises an annular termination (10) to be correspondently coupled to a tubular body (11) of the buttonhole (1) before being definitively fixed to the lamellar body (2), the buttonhole (1) which is immovably attached to the lamellar body (2) by the riveting (12) from one end of that tubular body (11), as the other end incorporates in its beginning a perimeter widening (13) as an edge terminal wing.
[0015] On the other hand, the immovable fixing of the buttonholes (1) to the lamellar body (2) is reinforced by a jagged end (14) established in the riveting (12).
[0016] There is also the possibility of incorporating other jagged (15) established in a washer (16) attached to the perimeter widening (13), in such a way that both this jagged (15) and the other jagged (14) will be in contact to the respective faces of the lamellar body (2), thus attaining a more secure and solid fixing between this one and the buttonholes (1).
1. DEVICE FOR FASTENING LAMELLAR BODIES, which is designed to fasten a lamellar body to the billboard structure or the like,
