Description

Metal grid element in particular for fence, and grid, leaf of

  Gate or gate comprising such a grid element The present invention relates to a metal grid element, in particular for fencing, comprising parallel bars connected in the vicinity of their two ends by at least two crosspieces

high and low respectively.

  The present invention also relates to a section for a grid or for a movable leaf of a gate or gate comprising such a grid element, a movable leaf of a gate or a gate or a grid.

  comprising at least one such section.

  Many elements of metal grids of the aforementioned type are known. For example, a grid element is known, the bars of which consist of tubes or solid bars, and the cross members of which consist of plates suitable for being arranged substantially horizontally, these plates being drilled for each bar with a hole allowing the passage of said bar. The bars are fixed in the sleepers in any known manner, for example

by welding.

  The choice of a grid is always the subject of a compromise between the rigidity and the resistance sought, on the one hand, the weight and therefore the final cost for the supply and installation on the site of the grid in question. , which we are always looking for

minimize, on the other hand.

  The object of the present invention is to provide a grid element of the aforementioned type which exhibits quite remarkable rigidity and resistance for a weight and a cost price as limited as possible, without neglecting the aesthetic appearance of such a device. grid element and its ability to form fences

  complicated contours in terrain with relief

may be injured.

  According to the present invention, the grid element of the aforementioned type is characterized in that each cross member is constituted by two transverse elements made of bent or curved sheet metal of substantially C-shaped section, each transverse element having a concavity turned towards said bars and being welded to each of the bars at the ends of the C section in contact with said bars, the bars being preferably tubes in particular of

circular section.

  The two transverse elements in folded or curved sheet are thus arranged on either side of the row of bars and communicate to the grid an inertia, and therefore a rigidity and a resistance, particularly high compared to the weight of

the grid element.

  The preferred bars in the form of tubes, in particular of circular section, also impart good inertia to the grid element, and therefore good

  rigidity and good resistance for a reduced weight.

  Furthermore, the costs of assembling such a

  grid element are relatively limited.

  The simplicity of the elements constituting the grid element according to the present invention, and the very favorable ratio between the resistance and the weight of this grid element make it possible to prepare prefabricated grid elements of large dimensions, for example having a width up to 3 to 4 meters, such grid elements remaining easily transportable and manipulated by hand and can therefore be installed very easily.

economical on site.

  FIG. 1 shows a section for a grid or for a mobile gate leaf according to an embodiment of the present invention. This section 1 mainly comprises a metal grid element 2 comprising parallel bars 3, adapted to be placed in particular in a substantially vertical position,

2791756

  connected in the vicinity of their two ends by at

  minus two crosspieces 4 respectively high and low.

  According to the present invention, the grid element 2 is characterized in that each cross member 4 is constituted, as shown in detail in FIG. 2, by two transverse elements 5 made of folded or curved sheet metal of section substantially in the form of C. Each transverse element 5 has a concavity facing the bars 3 and is welded to each of the bars 3, according to weld points shown diagrammatically at 6, at the ends of the C section in contact with said bar 3, very easily accessible. The bars 3 are preferably tubes

in particular of circular section.

  In the embodiment shown, the transverse elements 5 constituting the crosspieces 4 are

all identical.

  In the example of FIG. 2, each transverse element 5 has in cross section a shape comprising a central section 7 and two top and bottom side sections 8 and 9 each making an angle with

the central section 7.

  In this example, the two lateral sections 8, 9 form with the central section 7 two angles

  substantially equal and have substantially the same length.

  They are therefore symmetrical with respect to the mediator plane of the central section 7, this section being in the vertical position when the grid is vertical (see figures

2 and 4).

  It will be understood that the folded shape shown in FIG. 2 gives the grid element 2 a rigidity greater than that obtained with a transverse element made of simply bent sheet metal, due to the presence of the edges 11. In the section 1 for grid Figure 1,

6 2791756

  the grid element 2 is fixed to each of its

  transverse ends to a grid post 12.

  In the embodiment shown in detail in Figures 3 to 5, each post 12 carries, at each cross member 4 of the grid element 1, an adaptation part 13 arranged so as to fit between the two elements transverse 5 of said cross 4,

  preferably without the possibility of rotation.

  In the preferred embodiment shown in detail in Figures 3 to 5, each post 12 has a cylindrical shape and is a tube of circular cross section which comprises, for each cross member 4, a connecting member 14 adapted to be fixed to the post 12 and having a

adaptation part 13.

  Each connecting member 14 comprises a body 15 provided with an opening 16 of shape complementary to that of the post 12, of slightly circular section

  greater than that of the pole 12 in the present example.

  Thus, each connecting member 14 can be threaded onto a post 12 and fixed thereon at a predetermined height. It is thus possible to have two grid elements 2 located on either side of the same post 12 at two different heights, in steps, to follow the slope of the ground on which must be

  installed the grid according to the present invention.

  Similarly, the circular section of the posts 12 and of the opening 16 makes it possible to give two adjacent grid elements located on either side of the same post 12 different orientations to follow the

outline of the land to be fenced.

  Once placed at the desired height and in the desired direction, the connecting member 14 is fixed in position by a screw, not shown, screwed into the hole

threaded 17 of the body 15.

  The pole 12 located to the right of Figure 1 is shown separated from the grid element 2 for good

  illustrate the fitting of the adaptation part 13 between the two transverse elements 5 of the cross-member 4

  and the position of the connecting members 14.

  As shown diagrammatically in FIGS. 2 to 5, the adaptation part 13 comprises a front part 18 having in cross section a peripheral contour 23 corresponding, with the clearance necessary for easy assembly of the grid, to the internal contour 24 of the free end of a cross 4, an irregular octagonal contour in the present example. Such a polygonal contour ensures a very precise connection between the adaptation part 13 and the corresponding crossing 4,

  without any possibility of rotation.

  The front part 18 ends in the direction of the body 15 by a shoulder 19 having a height substantially equal to the thickness of the folded sheet forming the transverse elements 5, so as to extend towards the body 15 by a rear part 20 having a polygonal outer contour substantially in

  the alignment of that of the cross 4.

  Although this is not necessary, the grid element 2 can be fixed to the adaptation part 13 by a bolt or a rivet passing through the two elements.

  transverse 5 and the front part 18.

  As shown in detail in Figure 4, the body 15 of each connecting member 14 is offset relative to the adaptation part 13 in the direction corresponding to the axis 21 of a post 12, preferably of a length sufficient for two connecting members 14 arranged head to tail against each other on the same post 12 allow the establishment on either side of said post 12 of two crosspieces 4 having their axes 22 in the same plane 10 perpendicular at axis 21

post 12.

  In the embodiment shown in Figures 6 and 7, the gate 31 has two leaves

8 2791756

  pivoting, a first leaf 32 carrying a lock 33, represented on the right of FIG. 6, and a second leaf

  34 carrying a lock 35 which will be described later.

  Each leaf 32, 34 comprises a grid element 2 of the aforementioned type fixed at each of its transverse ends to a leaf amount, namely a load-bearing amount 36 carrying pins 37 for the articulation of the leaf and a non-load-bearing amount

  38 carrying the lock 33 or the lock 35.

  In the preferred example shown in FIGS. 8A, 8B, 8C, 9 and 10, each upright 36, 38 carries at the level of each crosspiece 4 of the grid element 2 an adaptation part 39 arranged so as to fit together between the two transverse elements 5 of said

  crosspiece 4, without possibility of rotation.

  In the example shown in FIGS. 9 and 10, the adaptation part 39 consists of two elements 40 of folded sheet metal fixed to the upright 36, 38 and having an external contour 41 complementary to the internal contour 24 of each transverse element 5, with a normal clearance allowing the assembly of these

elements between them.

  In the example shown, the uprights 36 and 38 are constituted by tubes of square section each carrying two adaptation parts 39 respectively high

  and bass welded on one side.

  To give each leaf 32, 34 the desired strength and rigidity, the grid element 2 is fixed, at the level of each cross member 4, to each of the uprights 36, 38, by means of a stirrup 42 passing around of the first adjacent bar 3 and urged towards the upright 36, 38 by a screw 43 screwed into a corresponding tapped hole of a support plate 44 to press the grid element against said upright

36, 38.

9 2791756

  As shown diagrammatically in FIGS. 8C, 18 and 19, the latch 35 slides inside the non-supporting upright 38 in which it is guided by a stirrup, shown diagrammatically at 46. The latch 35 is controlled by a handle 47 having a threaded end which penetrates through the opening 48 of the upright 38 to be screwed into the tapped hole 49 of the

lock 35.

  The opening 48 has at its upper part two lateral extensions 48a, 48b adapted to receive the handle 47 to maintain it in its high position while allowing the operation of the corresponding leaf, whatever the direction of opening of said leaf. The lock 35 is advantageously extended upwards by a cremone bolt 50 carrying at its upper part a washer 51 adapted to be locked, in the low position of the lock, by a dead bolt, not

shown, of lock 33.

  As shown diagrammatically in FIGS. 7, 12 and 13, in the case where the gate 31 is adjacent to a grid section 1 according to the present invention, the support upright 36 advantageously comprises pins 37 which pivot in supports 53 fixed to spacers 54

arranged between two posts 12.

  In the example shown in FIGS. 8A, 16 and 17, the pins 37 are advantageously mounted on a body 55 adapted to penetrate inside the corresponding supporting upright 36 and to be fixed at each end of this upright in any way , for example by screwing or welding, so that the pins 37 are placed in the axis of said upright 36 projecting from said upright, without closing this end to allow subsequent galvanization

said amount.

  In this example, each pin 37 is adapted to be pivotally received in the opening 56

2791756

  of a support 53 integral with a threaded rod 57 adapted to be received and fixed in a hole 58 of the corresponding spacer 54. In the example of FIGS. 12 and 13, each spacer 54 is formed of two transverse elements 59 having an internal polygonal contour 60 complementary to the external polygonal contour 23 of the adaptation part 13 of a connecting member 14 carried

by each post 12.

  The two transverse elements 59 are kept at a distance from each other by at least one section of tube 61 whose internal opening 58 is adapted to

  receiving the threaded rod 57 from a support 53.

  The spacer 54 is fixed at each end to a corresponding adaptation part 13 by a screw or

a rivet passing through hole 62.

  In the embodiment of FIG. 20, the grid comprises a gate 65 having a structure comparable to that of a leaf 32, 34 of the aforementioned type, but of appropriate reduced width, comprising a grid element 2 between a supporting upright 36 and a non-carrying upright 38 carrying a lock fitted to the

less than a latch bolt 66.

  In this example, gate 65 is installed

between two posts 12.

  The post 12 located on the right of the figure, carries the supports 53 of the pins 37 by means of screw collars 67 making it possible to clamp against the post 12 a support piece 68 receiving between two nuts 69 the

threaded rod 57 of the support 53.

  The non-supporting upright 38 of the gate 65 is received in a folded sheet metal structure acting as a frame 70 fixed to the other post 12 by a screw collar 67 and comprising an element 71 forming a keeper for

retain the bolt 66.

  It has thus been described a standardized grid element of simple and economical structure, which can be easily produced by welding bars and transverse elements of ordinary steel and which can be galvanized after assembly. Such a standardized element can then be simply and quickly assembled to posts which can be arranged relative to each other at varying distances and levels and in varying directions to follow the outline and the possible slopes of '' eventful terrain, to form a grid adapted to said terrain. The assembly of the grid elements 2 on the posts 12 is then done by means of identical connecting members 14 which can be, for example

  example, light alloy molded parts.

  The same grid elements can be used to form a leaf or gate leaves and / or a gate which may or may not be

associated with a grid.

  It is also possible to bend the transverse elements 5 before assembling the bars 3 to

  make curved grid elements 2.

  All these sub-assemblies have both a satisfactory level of rigidity and resistance and a relatively limited weight, all associated with simplicity of assembly and assembly on any site. By way of nonlimiting examples, it is possible to use, for the bars, tubes with an outside diameter of about 28 mm and a thickness of about 1.25 mm, for the transverse elements 5, folded sheet elements of thickness 1, 5 mm and a total height of about 50 mm, for posts 12 of tubes with an outside diameter of about 70 mm and a thickness of about 2 mm, for uprights 36, 38 of tubes with a square section of

mm side.

  Of course, the present invention is not limited to the embodiments described and shown, and may have brought many changes to these.

  and modifications without departing from the scope of the invention.

  It is thus possible, for example, to replace the C-shaped section of the transverse elements with a section of different shape giving these transverse elements the desired strength and rigidity. It is then easy to adapt the connecting members and the adaptation parts to the profile adopted for said transverse elements.
