Description

Fence grid

The present invention relates to a fence grid, as well as a gate comprising a frame on which the fence grid is mounted.

A fence grid conventionally comprises at least one smooth and several bars fixed to the smooth. In general, once the fence grid is up, the rail extends horizontally and the bars extend vertically.

In this context, systems are known which make it possible to block vertical bars in a horizontal rail. The document US 4610109 discloses for example a grid comprising a horizontal smooth and vertical bars crossing the horizontal smooth. Each vertical bar includes a through hole extending into a portion intended to be housed in the horizontal rail. The grid further comprises a rod or a cable passing through the bars through the through holes and fixed on either side of the rail to the end bars.

The solution proposed by this document is not completely satisfactory, in particular for very long grids. Although the vertical bars are fixed in the horizontal rail thanks to the rod or the cable, these can move slightly, or even deform in the vertical plane over time.

The present invention aims to solve at least one of the aforementioned drawbacks by proposing a grid whose immobilization of the bars relative to the smooth is improved.

The invention relates to a fence grid comprising at least one rail and bars mounted in said at least one rail, each bar comprising a through hole extending in a mounting portion of the bar housed in said at least one rail.

According to the invention, the grid further comprises two rods and an assembly accessory, each rod passing through a subset of said bars through the through holes and being fixed at a first end to said assembly accessory.

The proposed solution thus makes it possible to simply block the movement of the bars in the rail. In such an assembly, the assembly accessory is advantageously found between two bars, which further improves the immobilization of the bars.

Thanks to the assembly accessory, it is also possible to build very long grilles while avoiding the movement and deformation of the bars.

In addition, the use of two rods facilitates the assembly of the grid. Indeed, each rod passing through a subset of bars and not all the bars, it is easier to introduce the rod into the through holes of the bars during assembly. In this regard, each rod can be sized or cut at the time of assembly so as to have the appropriate length to be introduced without difficulty into a subset of bars.

Moreover, the grid thus formed is modular. During assembly, the bars are housed successively in part in the rail and each bar subassembly is immobilized by means of the rod. It is thus possible to easily modify the aesthetic aspect of the grid according to the desire, for example by putting bars of different colors.

Finally, the modularity of the assembly is also given by the possibility of shortening the length of the grid easily at the time of assembly. In particular, the rods and the stringer can be cut to the desired length.

According to one feature, the assembly accessory extends along the length of said at least one rail, the assembly accessory having a length substantially equal to the length of the space between two bars.

The assembly accessory thus dimensioned can be wedged between two bars so as to block its movement and in particular its translation inside the rail.

According to one characteristic, said at least one rail is a hollow profile defining a cavity in which is housed the mounting portion of the bars, the cavity being filled with an insulating foam extending between the bars.

The insulation foam thus arranged makes it possible to further block the movement of the bars. Indeed, it fills the void or play in the rail and in which the bar could move.

In addition to the advantage of structural strength, this avoids sound vibrations due to the movement of the bars in the arm under the effect of the wind, for example.

Finally, the insulation foam makes it possible to ensure the tightness of the grid and thus protect it from the infiltration of rain, for example.

According to one characteristic, the grid has two end bars between which the other bars extend, each rod being fixed at a second end to a fixing piece coming into contact against one of the two end bars.

The maintenance of the immobile bars is thus also ensured on either side of the arm.

According to one characteristic, each fixing piece comprises an opening configured to allow the introduction of an insulation foam into said at least one rail.

The opening thus allows the introduction of the insulation foam once the assembly of the bars in the rail is finished. The insulation foam can be an expanding foam.

According to one characteristic, one end of said bars is housed in said at least one smooth.

In other words, the rungs do not cross the rail. This avoids the risk of injury and accident, especially when the fence grid is used to delimit a children's play area.

According to one characteristic, the grid comprises two smooth, the bars being mounted at each end in the two smooth.

According to one feature, the grid comprises four rods and two assembly accessories, each bar comprising two through-holes each extending into a mounting portion housed in one of said two smooths, each rod passing through a set of bars through the through-holes and being fixed at a first end to one of said two assembly accessories.

According to one characteristic, the rod is fixed by screwing into a tapped hole of the assembly accessory.

This makes it easier to attach the rod to the assembly accessory and the fastener. The rungs are held fixed in each of the two rails.

In one feature, each rod is a full-length threaded rod.

The rod can thus be shortened at any place without worrying about the need during cutting, to keep an area comprising a thread.

The invention also relates to a gate comprising a frame on which is mounted a fence grid having the preceding characteristics.

Other particularities and advantages of the invention will appear further in the description below with reference to the appended drawings, given by way of non-limiting examples:

Figure 5 is a perspective view of the grille mounted to a frame of the gate of Figure 4;

Figure 6 is a detail view of an assembly system between the frame of a gate and the grid;

Figure 7 illustrates the assembly system of Figure 6 in cross section; And

Figure 8 is a perspective view of a grid according to another type of embodiment mounted on the frame of a gate.

Figure 1 shows a fence gate 1 according to an embodiment according to the invention. Grid 1 comprises at least one smooth 2 and bars 3 mounted in said at least one smooth 2. In the example shown, grid 1 comprises two smooth 2; an upper rail and a lower rail.

The bars 3 extend here substantially perpendicular to the smooth 2. As visible in the figure, each smooth 2 is generally adapted to extend horizontally once the grid 1 is mounted and the bars 3 to extend vertically.

In the rest of the document, length means the dimension in a direction parallel to the horizontal direction or to the direction of extension of the arm.

The heddles 2, and likewise for the bars 3, being here all similar, the description is made for each element individually, namely for a heddle 2 and a bar 3.

Smooth 2, as seen in Figures 2 and 3, is here a hollow profile having faces and a cavity 21 delimited by said faces. Smooth 2 here has a rectangular cross-section and therefore cavity 21 is also rectangular.

The heddle 2 comprises orifices 22 opening onto a mounting face 23. Each orifice 22 has a section substantially equal and similar to the cross section of the bars 3. Each orifice 22 thus allows the introduction of a bar 3 into the heddle 2 The orifices 22 of the rail 2 are in this example non-through, so that the bar 3 does not pass through the rail 2.

The bar 3 is here tubular.

A mounting portion 30 of the bar 3 is housed in each smooth 2. In particular, a mounting portion 30 of the bar 3 is housed in the cavity 21 of each smooth 2.

The bar 3 comprises two ends 31.

Each end 31 of the bar 3 is here housed in one of the two smooth 2. In other words, the assembly portion 30 of the bar 3 housed in each smooth 2 comprises the end 31 of the bar 3.

In another embodiment, the bar 3 can pass through the heald(s) 2, and the bar 3 can be fixed in the heald 2 at a level other than its ends 31.

The bar 3 comprises at least one through hole 32, clearly visible in Figures 2 and 3. The through hole 32 here has a substantially circular section. The through hole 32 extends into the mounting portion 30 of the bar housed in the rail 2.

In this example, the rung 3 comprises two through-holes 32. A through-hole 32 extends into each mounting portion 30 of the rung 32. A through-hole 32 thus extends through each heddle 2.

Grid 1 further comprises at least two rods 4 and at least one assembly accessory 5. Grid 1 also comprises at least two fixing parts 6.

In the example illustrated, and as seen in Figure 1, the grid 1 comprises four rods 4. Each rod 4 passes through a subset of bars through the through holes 32. Two rods 4 pass through the bars 3 in the top rail and two rods 4 pass through the bars 3 in the bottom rail. Each rod 4 is thus housed in one of the two smooth 2.

The elements and their assembly being all similar, the description is made below initially for a rod 4 fixed on the one hand to an assembly accessory 5 and on the other hand to a fixing part 6.

The rod 4 comprises a first end 41 and a second end 42. The first end 41 of the rod 4 is fixed to the assembly accessory 5. The second end 42 of the rod 4 is fixed to the fixing part 6.

The rod 4 is thus configured to hold the bars 3 of the subset of bars that it crosses, immobile in the smooth 2.

By rod is meant a thin and elongated element which can be introduced into the through holes 32 of the bars 3.

Rod 4 is preferably a full length threaded rod.

Of course, the rod 4 can be threaded only on one part. In particular, the rod 4 can be threaded only at one end intended to be screwed.

Assembly accessory 5 extends along the length of beam 2.

The assembly accessory 5 here comprises two transverse walls 51 and two longitudinal walls 52 extending perpendicularly to the transverse walls 51.

The assembly accessory 5 advantageously has the same cross section as the cross section of the heddle 2. Thus, the assembly accessory 5 here has a rectangular cross section. In other words, the transverse walls 51 have a rectangular shape.

The transverse walls 51 have dimensions slightly smaller than the dimensions of the cavity 21 of the smooth 2. Or more generally, the assembly accessory 5 has a rectangular cross section slightly smaller than the cross section of the smooth 2. In this way, the rotation of the assembly accessory 5 in the smooth 2 is blocked.

The assembly accessory 5 comprises two tapped holes 53 on either side. The tapped holes 53 are formed at the level of the walls configured to receive the rods 4. In the embodiment described, each transverse wall 51 comprises a tapped hole 53.

The assembly accessory 5 is thus configured to allow the fixing of two respective first ends 41 of two rods 4 by screwing into the tapped holes 53 of the transverse walls 51.

Advantageously, the assembly accessory 5 has a length substantially equal to the length of the space between two bars 3. In this way, the assembly accessory 5 is blocked in translation once the grid is mounted, as explained more far.

The assembly accessory 5 thus forms in this embodiment a spacer between two bars 3.

The fixing piece 6, clearly visible in Figure 3, is placed against an end bar of the grid 1. By end bars is meant the two bars 3 of the grid 1 between which the other bars extend.

The fixing part 6 comprises a hole 61 configured to receive the rod 4. The second end 42 of the rod 4 is fixed to the fixing part 6 for example by means of a nut 62.

The fixing part 6 can be a rectangular part, for example a wedge.

The fixing part 6 comprises an opening 63. The opening 63 of the fixing part 6 is configured to allow the introduction or injection of an insulating foam (not shown) into the rail 2.

The insulation foam is preferably an expanding foam.

The insulation foam makes it possible to block the movement of the bars in the arm 2. This prevents the vibration of the bars 3 which can generate a noise nuisance.

The insulation foam also makes it possible to seal the grille 1.

The insulation foam is for example polyurethane foam.

Advantageously, the fixing part 6 extends inside the smooth 2. The immobilization of the bars 3 in the smooth 2 by means of the rod 4 is thus carried out while maintaining the fixing means, here the parts of fixing and the assembly accessory, hidden inside the beam.

When fitting the grid 1, an assembly accessory 5 is placed beforehand in each rail 2.

Each bar 3 of a first subset of bars 3 is introduced by one end 31 into one of the two heddles 2. In the example shown, each subset of bars has ten bars 3.

Once the bars 3 of the first subset of bars have been introduced into one of the two healds 2, a first rod 4 is introduced into the heald 2. The first rod 4 crosses the bars 3 through the through holes 32 then the tapped hole 53 of assembly accessory 5.

The first rod 4 is then screwed at the first end 41 into the tapped hole 53 of the assembly accessory 5.

Finally, the first rod 4 is fixed at the level of the second end 42 to the fixing part 6 coming into contact against an end bar.

The same assembly steps are repeated for the other subset of rungs or second subset of rungs in the same rail 2.

Once the rungs have been fitted in the rail 2, the assembly accessory 5 is fixed on either side to the two rods 4.

In the example illustrated, the length of the assembly accessory 5 being substantially equal to the length of the space between two bars 3, the assembly accessory 5 is thus wedged between two bars 3. In particular, the assembly accessory 5 is wedged between the tenth and the eleventh rung. The assembly accessory 5 is thus locked in translation.

Furthermore, each rod 4 is fixed to a fixing part 6. The bars 3 are thus kept perfectly immobile.

Once the mounting of the rods in the rail 2 has been completed, that is to say that the rod 4 is fixed at its two ends 41, 42, the insulation foam can be injected through the opening 63 of each part fixing 6. The insulation foam being expansive, it then extends between the bars 3.

The assembly of the bars 3 and the rods 4 in the second smooth 2 is similar and is therefore not described.

FIG. 4 represents a gate 7 comprising two frames 8 to which are mounted two grids 1 such as the grid described above. The grids represented in this figure are of shorter length than that of FIGS. 1 to 3, but have a structure similar to the latter.

Each frame 8 of the gate 7 comprises two uprights 81 and two beams 82 extend perpendicular to the uprights 81. In general, when the gate 7 is mounted, the beams 82 are horizontal and the uprights 81 are vertical.

The gate 7 also comprises two posts 9 extending parallel to each other and on either side of the two frames. The posts 9 are parallel to the uprights 81, here vertical. Each frame 8 is for example pivotally mounted with respect to one of the posts 9.

The structure and assembly of Portal 7 are classic and do not need to be described in more detail.

FIG. 5 shows, with certain elements placed in transparency, the grid 1 mounted on a frame 8 of the gate 7. In particular, the upper rail of the grid is removed.

Each smooth 2 is mounted on a longitudinal face to a beam 82, and on its ends to the two uprights 81 of the frame 8.

Each grid 1 is mounted here having turned each rail 2 by a quarter turn relative to the mounting of the grid 1 in the example illustrated in Figures 1 to 3.

An assembly system 10 of the rail 2 to the beams 82 of the grid 1 is shown in Figures 6 and 7.

The assembly system 10 comprises a first assembly element 101 and a second assembly element 102 configured to cooperate together. The first assembly element 101 can be mounted or formed in each heald 2. The second assembly element 102 is mounted or formed in each beam 82.

In the example illustrated, each rail 2 comprises at least one insert projecting from the longitudinal face. The insert forms the first assembly element 101. The insert is for example a threaded insert.

Each beam 82 of the gate 7 also includes at least one through perforation 83 and opening onto a mounting face configured to be fixed to the longitudinal face of one of the two healds.

A wedge 84 is placed against an internal face of the beam 82. In other words, the wedge 84 extends inside the section of the beam 82. The wedge 84 has a substantially rectangular shape and includes a hole. The hole has substantially the same dimensions as the perforation 83. The wedge 84 is thus configured to surround the perforation 83 and forms an internal rim around the perforation 83.

The perforation 83 of each beam 82 is formed so as to face the insert of each rail.

In order to fix each beam 82 to one of the heddles, a screw 102 is introduced and then screwed into the insert of the heddle. The screw here forms the second assembly element 102

The fastening system further comprises a masking element 103. The masking element 103 is configured to mask the fastening or the assembly between the beam 82 and the smooth 2, and in particular between the first assembly element 101 and the second assembly element 102.

The assembly element 103 is here a cap. The plug is introduced into the perforation 83 of each beam 82. The plug thus makes it possible to prevent access to the screw.

The wedge 84 forming an internal rim around the perforation 83 makes it possible to block the stopper 103 in the beam 82.

Advantageously, the plug is flush, that is to say it is pushed into the perforation 83 and does not project from the beam 82. The plug can thus no longer be removed without being destroyed.

Several assembly systems can be used to attach each rail to the gate frame. In particular, two fixing systems can be used to assemble each rail to each beam, thus allowing a solid mounting of the grid to the frame.

The fixing system as constituted makes it possible to obtain an assembly without fixing or visible hole. This improves the aesthetic appearance of the gate and the grille.

The mounting of a gate on a gate by means of the fastening system described applies for a gate as described in relation to figures 1 to 3 but also for a gate of different structure as illustrated in figure 8.

FIG. 8 represents a fence grid 11 comprising two healds 12 and bars 13 mounted in the two healds 12. Each bar 13 comprises two through-holes 132. Each through-hole 132 extending in a mounting portion 120 of the bar 12 housed in one of the two healds 12.

The grid 11 comprises two rods 14. Each rod 14 passes through the set of bars 13 through the through holes 133. A rod 14 thus extends into each smooth 12. Each rod 14 is fixed at its ends 141 to parts fixing 15 coming into contact with the end bars.

It will be noted that the heddles 12, the bars 13 and the fixing piece 15 are identical to those described above with reference to Figures 1 to 3.

Grille 11 is mounted to a frame 8. The top rail has been removed from the figure to illustrate the inside of rail 2.

Of course, the present invention is not limited to the embodiments described and illustrated.

The assembly accessory may have a different shape and dimensions. The assembly accessory can for example comprise two transverse walls and a longitudinal wall, thus having a U or C shape.

The length of the assembly accessory can be smaller than the length of the space between two bars.

The present invention thus proposes a fence grid whose immobilization of the bars relative to the smooth is improved, and whose structure is modular.
