The invention which is herewith defended consists of a do-it-yourself mounting grille conceived for assembly on windows, fences and the like.
The object of the invention is a grille configured by various mounting elements, consisting of thick flat bars and tubes or bars placed perpendicularly arranged, of equal thickness, as well as additionally including threaded rods or profiles as stiffening and joining means between tubes and flat bars, considering the possibility of using break head nuts.
Likewise, an object of the invention is that the grilles include means of attachment to the strengthening element of the building to be applied on windows, the flat bars also being used on fences as right hand feet.
Grilles constituted by standardised elements in modulated dimensions are previously known.
Specifically, Utility Model ES-U-1034506 entitled "Profiles for the construction of grilles and other door and window closures" belong to the same applicant, which describes elements which constitute the grille, said dimensioning being stepped to preset measures, in such a manner that the user may construct his own grille, after selecting the parts with appropriate length, the next and nearest length, so that he may cut the excess ends with a saw and next, integrally assemble the same.
The development of a modular grille for application on windows, fences and the like, by using a series of constructive elements with easily assembled joining means makes the invention which is herewith described, feasible.
It is known the way for joining horizontal bars and vertical ones as the ones disclosed in US 5609002, FR 2496153, GB 1155090, DE U9102356, US 2877989 patents. Basically the way for fastening horizontal and vertical bars is based either in the use of nuts and screws which pass through both bars or based on the used of vertical bars whose ends are recessed being threaded for being used in collaboration with nuts. In our invention we propose a different way for fastening both horizontal and vertical bars where the vertical bars do not pass through the horizontal ones so both horizontal and vertical bars are provided with cooperative means for joining both bars. Using a through stem or spherical head screw both joined to the horizontal bar by means of welding, or by means of insertion of the vertical bar into the horizontal one, having this last one perforations with confronted wings.
The present invention as defined in claim 1 refers to do-it-yourself mounting grille for assembly on windows, fences and the like, which is very easily transported and presents simplicity of the means necessary for its assembly in situ.
The claimed grille is provided with longitudinal components and transversal components with standard measures, ready for forming the grille by the simple integral joining of said groups, using in a possible embodiment, break head nuts.
The object of this invention is constituted by the indistinctly horizontal or vertical arrangement of the elements which make up the grille, as well as its construction by means of flat bars and tubes or bars, in a possible embodiment including in one of said tubes, a threaded rod which crosses at its ends, various flat bars to which it is joined by means of break head nuts.
The tubes may be assembled according to different embodiments, considering in one possible embodiment, inserting the screw heads inside the tube ends, and that their threaded bodies project and insert through an orifice of the flat bar to which the tube is joined with the help of a break head nut.
Another solution consists in that the tubes be provided with screws fixed to their ends, which are joined to the flat bars in the same manner.
Another possibility consists in the use of solid bars instead of tubes, contemplating that the bar may be perforated on its intermediate zone so that attachment parts may couple to the flat bars.
If bars are used, inserting them by their ends on orifices performed in the flat bars and subsequently joining them by means of profiles, may be resorted to.
Likewise, it must be pointed out, that the grille includes wall coupling means, which consists of an angle iron screwed to one of the flat bars and to the wall, which may or may not finish off with a ripped end, open towards its sides, or else may consist of a small coupling plate on the flat bar which ends at a ripped end, open towards its sides.
In the application of grilles for fences, the flat bars of the grilles shall be placed as right hand feet of the construction, advantageously anchored to the ground, contemplating that a part of the tubes configure horizontal fence spars joined to the flat bar by means of attachment nuts, providing, that the adjacent flat bars be joined by means of a bushing which covers said attachment nuts between colinear horizontal tubes.
In the case of being used as a fence, it is provided that the grille include defence means placed on the upper horizontal tube to which it is screwed.
It is known in the state of the art different ways for conforming a mounting grille for windows and fences such the ones described in the US 4667935, EP 494387 and US 5609002. The ways described in such patents present a common feature, the vertical bars pass through holes done in the horizontal bars, which additionally could employ some screw for a better fastening. Now we propose different ways for fastening vertical and horizontal bars where the vertical bars do not pass through any hole or perforation done in the horizontal bars, so it has been necessary to develop ways for fastening where the ends of the vertical bars are attach to the flat bars without passing through any hole, as the vertical bars finish in the flat bars.
So the objective of the present invention is to develop ways of fastening between the ends of the vertical bars and the horizontal ones, without passing through any hole.
In order to complement the description which is being carried out, and with the object of facilitating a better and easier understanding of the characteristics of the invention, the present Specification is enclosed, forming integral part of the same, with a set of drawings in which, with illustrative and never limitative character, the following has been represented:
In view of the described figures, a preferred embodiment of the do-it-yourself mounting grille is herewith described, which is mainly found constituted by flat bars (2) and tubes (3), (4), or bars (12), (18), (33), (34), (35) perpendicularly coupled by corresponding joining means and which is applicable for assembly on windows or fences.
In one possible embodiment, the tube (3) internally includes a through rod (4) which projects by its ends and crosses the flat bars (2), against which they fit by means of break head nuts (1) until the torque applied on the same breaks its hexagonal head.
The rods (4) may be included in the tubes (3) of the end side of the grille, as well as in other intermediate tubes (3) of the grille when advised by the length of the grille.
Detail A of figure 1 shows the attachment between tube (3) and flat bar (2) by means of a break head nut (1) whilst detail B shows two variants of tube (3) attachment to the flat bars (2), either by means of a pivot (7) or through screw, joined to the flat bar (2) by means of welding or else by means of a spherical head screw (7') inserted in a spherical slot (2') of the flat bar (2) to which it is joined by welding.
In another embodiment, which does not form part of the invention it is contemplated, that the tubes (3) be provided at their ends with various inserted head screws (13).
On the other hand, in order to adapt the length of the profiles to the grille dimensions, it is considered including another type of tube (14) which is equipped with a screw (15) at one of its ends, capable of being cut at the other end to adjust its length; before inserting it in lugs (16) defined on the flat bars (2), as well as being provided with perforations (17) through which the reinforcement bars may be inserted.
Other bars (18) have perforations (19). for the insertion of joining means with attachment parts (20) which immobilise the flat bars (2).

It is contemplated, that the orifices (27) of the flat bar (2) be through orifices and that they coincide in their shape, with the section of the bars (33).
The grilles may likewise include bars (34) which are provided with a perimetral recess (28) near their ends to house the ends of confronted wings (29) of the union profile (26).
In another possible embodiment, a bar (35) is available which is provided at its ends with a blind boss (30), adapted for inserting a screw (32) with break head which previously crosses the orifices (27) of the flat bar (2).
The different attachment means of the grille to the wall of figure 2 which do not form part of the embodiment of the invention consist of an angle iron (5) which includes a hole (21) with threaded nut (22) inside for insertion of a torque screw which ties down on the flat bar (2), and which is provided with perforations (6) on the previous orthogonal area for screwing to the wall.
The angle iron (5) may include a free end (5'), ripped and open like claws.
Other attachment means may consist of a small plate (23) which includes, a hole (24) with an internal threaded nut (25) for insertion of a torque screw which ties down on the flat bar (2), and an end (23'), equally ripped and open as attachment claws.
In the application of grilles for fences, the flat bars (2) are arranged anchored to the ground and are to be found in pairs with the help of bushings (9) covering the joining nuts (1) between the flat bars (2) and the tubes (3).
The grille contemplates the inclusion of defences (10) screwed to one of the tubes (3) which constitute an upper fence spar.
