Description

The present invention relates to fence elements and, in particular, those constituting barriers, gates, gates etc ...

 The assembly and installation of the fence elements generally require specialized tools and on-site welding operations with the intervention of a person skilled in the art, then an expensive periodic painting maintenance, in particular with c the painted wooden and ferrous metal parts.

 In the case of barriers and fences made of heddles in P.V.C. plastic, which dispenses paint, this results in a very rapid viealissement of the fragile material which quickly becomes brittle.

 The aim of the present invention is to provide a solution to all these drawbacks by producing more reliable barriers and fences with the use of materials having an unlimited duration, dispensing with any maintenance and allowing the assembly of the constituent elements, then installation, without the need to have recourse to a person skilled in the art and to specialized tools.

 The present improvements are also intended to improve the operation of the gates and gates by an automatic locking device, forming a stop, in the open and closed position.

 The invention is explained in more detail by the drawings listed below: FIG. 1 is a perspective view of a double gate according to the invention.

FIG. 2 is a perspective view of a portion of the fence.

-Figures 3, 4 & 5 represent, in perspective, the assembly of the various elements together and their attachment to the small walls and fence post.

-Figures 6,7,8,9 & 10 represent examples of forms of bars and heddles for covering the gates and other parts of the fence.

-Figures 11,12 & 13 show the automatic locking device, with its unlocking, of a stop located at the base of each gate or gate in the open or closed position.

FIG. 14 represents a detail of the manual control of the device for unlocking the automatic locking.

FIG. 15 represents a manual floor lock device.

 In order to eliminate all maintenance and, in particular, periodic painting, the constituent elements of the structure of gates and fences are made of square or rectangular metal tubes or profiles, etc.

either in aluminum or treated alloy: anodized, galvanized iron, or other materials treated against oxidation.

 The frame elements of the gates and fences can be assembled and welded together then, if necessary, treated against oxidation in the workshop, or composed of interlocking elements assembled by screws, bolts, rivets, clips, etc. , sold and delivered in separate parts with the bars, cover rails and all accessories for assembly and installation by the user.

 To make all of these gates and fences maintenance free of paint and give them perfect mechanical resistance with great durability, the bars and heddles are made of good quality non-aging materials such as laminated polyester, aluminum anodized, sheet of galvanized metal or prepainted in the oven, etc .. resistant to atmospheric agents.

 In Figure 1 we see that the components of a portal are smooth 1 & 2 forming a frame with the uprights 3 & 4 and possibly an oblique reinforcement crosspiece 5.All these elements can be welded together and then treated against oxidation (case of ferrous metals pargalva- nization).

 Figure 2 gives an example of a portion of the fence on a sideboard wall. The frame is formed of the beams 11 & 12 and the uprights 13 & 14.The upright 13 carries fixing lugs 13A & 13B bolting respectively on recipes 13C & 13D sealed in the post 8.Front of the lower end of the intermediate upright 15, a lug 15A is bolted to a recipe 15B sealed with the sideboard hutch 16.

 If the various elements making up the frames of the gates and fences can be welded together and treated against oxidation in the workshop and delivered thus constituted, they can, also, be delivered in spare parts and assembled on the site of use without recourse to Those skilled in the art. Their design and preparation mean that they can also be made of pre-treated metal, for example, galvanized iron, stainless steel, or anodized aluminum.

They are assembled using screws, rivet bolts, clips, etc.

 FIGS. 3,4 & 5 are intended to represent the assembly details. The healds 11 & 12 and the uprights 13 & 14 are in square or rectangular tube and are assembled by interlocking on corner pieces 17A, 17B, 17C, 17D, 17E, 17F etc ... of metal or similar or different material on which they are fixed according to the means described above.

 Same thing, for the intermediate uprights16 figure 4. Some of these parts can, moreover, include any organ or conformation proper to its position or function as a portal pivot, above 17G, or below 17H, sealing lugs 15A on 17E (fig. 5) etc ...

In Figure 10 the vertical post 40 carries a horizontal rail
40B of corrugated section with single or multiple corrugations similar to those
10 A bars lining gates and fences; but the conformation of this
element, bar or smooth, can take various indicative forms and not limited
tatives, like those shown in Figures 1,2,6,7 * 9 & 10.

 Depending on the materials and various materials used, these ribbed shapes, in order to obtain good rigidity combined with the decoration, can be obtained by stretching, molding, pressing, stamping, etc.

 The preferred, but nonlimiting, materials, such as molded laminated polyester and pre-coated and corrugated aluminum sheet, are particularly suitable for making beams or bars of the shapes indicated above.

They are fixed to the frame of gates and fences by screws, bolts or rivets.

 The bar # 0A, waved longitudinally and shown in FIG. 6 can receive, at one or both ends, a finishing end piece LOB which can be fixed by the same means as that for fixing the bar itself to the frame. of the closing item concerned.

 The variant shown in FIG. 7 has one or more hollow parts in its central longitudinal axis so as to ensure its rigidity and its contact at the points of its attachment to the beams il & 12.

 Figure 9 shows another example of profile and possible undulation for such a horizontal bar or beam.

they
All these examples are only indicative, should not constitute a limit to the possibilities of forms of bars or heddles entering the spirit of the invention which relates to the realization and the conformation of these parts obtained from suitable materials in single thickness but dispensing paint maintenance hollows and whose undulations, grooves, or bosses have, not only the purpose of ensuring their stiffening, but also an aesthetic decorative aspect and fixing points on the frames or structures of the elements of fences.

 In order to make the operation of the gates, object of the invention, easier, a new type of latch sealed on the ground allows automatic blocking in the open or closed position, for each leaf.

 According to Figures 1,11,12 & 13, this floor latch consists of a sole 20 #, preferably metallic, bearing ground sealing lugs 20A, 20B and a stop 20C limiting the movement of the leaf of a gate. considered.

 The sole 20 has on both sides a vertical edge 20D & 20E between and on which is articulated a lever 21 forming a latch by the fact that the part 21A opposite the stop 20C is lighter than the part 21 B opposite by relative to its hinge pin 22, so that at rest said latch occupies the position shown in Figure 11 in solid lines or the weight of part 21B does not hold the lever in this position. Note that a spring can help that the latch 21 is ensured to take this position at rest.

We see that thus the gate 30 is trapped between the latch 21 and the stop 20C.

If a push F1 is printed towards #as, on the lever at 21A it pivots and lowers; the gate 30 is then released and can be released according to F3
Figures 1 & 13 show a floor latch Ai or A2 intended for blocking in the closed position of each leaf of a portal considered. The leaf A being held by the latch Ai and the leaf B by the latch A2.

Towards the end of the respective closing movement of each leaf, its lower part engages on part 21B of the latch 21 which automatically lowers its part 21A until the leaf comes into abutment with 20C, then 21A is released, the latch switches and 21A rises while holding captive the leaf between it and the stop 20C.

 Each leaf can be fitted with a set of 2 latches, one for closing it and another for keeping it in the open position. However, a single latch can satisfy a set of 2 A & B leaves from the same gate, to ensure the closing; in this case, the single latch will be placed at the junction of the said leaves so that when the first closes, the latch lowers and blocks it, then, when the second leaf closes, let it lower again and finally lock the 2-wing in turn, so the two together.

 Figures 13 & 14 shows # t the detail of the operating principle and key locking of the two leaves A & B and unlocking the floor latch from the outside of a property as well as an additional device for gate lock.

 According to Figure 13, the leaf A has a lock 30; The handles 31A & 31B are connected together through this lock by the shaft in square section 31C integral in its rotational movement with a hoe 32 forming control lever d 'a vertical rod 33 articulated at 32A on said. hoe and sliding, parallel, to the upright Al, in guides 33A & 33B integral with the latter. The lower end of the rod 33 presses on the part 21A of the floor latch, when the handles 31A or 31B are actuated along X and this latch which releases the leaf concerned / can then open lowered the latch which releases the leaf concerned p can then open.

 The link 32 has an appropriate conformation such that a lug 32B is blocked, in its movement, when the bolt 30A of the lock is in the "locked gate" position so that it is then impossible to actuate the latch of ground and open the gate from the outside.

 FIG. 15 represents a vertical manual floor lock housed inside the vertical upright B of a gate leaf. It consists of a rod 40 with at least 2 concentric cylindrical rings or part 40A & 40B of an appropriate diameter allowing them to slide with the necessary clearance inside the hollow profile constituting the amount of the gate. A perpendicular handle 40C to the lock rod 40 and, preferably secured to it by screwing, is used for the operation of said lock. This handle evolves and is guided in a 40D light, with locking notch in the "bolt removed" position, open on the B-pillar of the gate and acce.ssible, on the interior side of the property, on it. A 40E ring comes in abutment under the bolt of the lock to then condemn any operation of the lock.
