The relief (4) is in the form of a fold at right angles or substantially at right angles or a segment of a cylinder. An apron made using this type of sheet can be used either way round without any risk of injury for the wearer.

Description

PROTECTIVE BODY CONSISTING OF PLATES ASSEMBLED BY RINGS AND APRONS OBTAINED WITH THIS TYPE OF BABY

The present invention relates to an improvement to the plies consisting of plates assembled by rings; it also relates to protective aprons made with this type of ply.

Aprons made with current tablecloths, of the type described in document EP-A-0 284 696, that is to say tablecloths made up of simple round metal plates, square or rec angular, or of similar shape, do not offer total security. For this type of article, the plates are partially superimposed, always in the same direction, in rows.

This arrangement of the plates implies a very precise sense of use of the apron.

These protective aprons are sometimes doubled front and back by a plastic or other fabric which protects the user against dirt due to friction on metal plates. The user can inadvertently position the apron upside down and thereby run the risk of injuring themselves with a sharp point which could pass between the pads.

The present invention provides an improvement to this type of sheet to avoid this type of drawback.

The sheet according to the invention consists of plates which are shaped with a relief generating, alone or in cooperation with an adjacent plate, a kind of obstacle or abutment for the tip of a sharp member capable of sliding and to be introduced between two plates.

According to a first embodiment, the relief consists of a fold in the square or substantially in the square formed at an edge of the plate, which fold is oriented towards the adjacent plate and gives said plate a section in L.

According to a second embodiment, the relief consists of two folds at right angles or substantially at right angles, formed on one side and on the other of the plate, at the level of two opposite edges; these folds are oriented towards the adjacent plates which overlap them and give said plate a Z-section.

According to another embodiment, the relief consists of two folds at right angles or substantially at right angles formed on the same face of the plate, at the level of two opposite edges; these folds are oriented towards the adjacent plates which overlap them and give said plate a U-shaped section.

According to another embodiment, the relief is in the form of a vault giving the wafer the appearance of a cylinder segment whose section is in an arc of a circle.

For these last two embodiments, the plates overlap in the manner of channel type tiles having the same U shape or in an arc, constituting a roof.

According to another embodiment, the relief consists of folds at right angles or substantially at right angles, arranged at all the edges of the wafer.

The invention also relates to the protective apron made by means of a sheet using this type of plate. The reversibility of this apron allows in particular the addition of a single protective sleeve, in chain mail for example, for the protection of the shoulder in the case of cutting work at height.

The invention is detailed with the aid of the following description and the appended drawings, given by way of indication, and in which: FIG. 1 illustrates, seen in profile, a sheet according to a first embodiment;

FIG. 10 represents the chain mail panel grafted onto the apron of FIG. 9.

Figure 1 shows, in a section AA of Figure 8, the assembly of plates 1 constituting a sheet. These plates have a generally rectangular shape; they are assembled by means of junction rings 2, via passage holes 3 arranged for example in the corners, as shown in Figures 4a and 4b.

Note, Figure 1, a sharp point _A disposed on one side of the web and another tip 13 disposed on the other side of the web.

On conventional tablecloths, in accordance with the state of the art, when it moves up and down, the tip _A slides on the pads without the possibility of penetration between two adjacent pads. On the other hand, the tip 15, when it moves up and down, can, by sliding on the plates, penetrate between two adjacent plates.

To stop the progression of the point B_ between the adjacent plates, the invention proposes to have an obstacle at the level of the overlapping parts of the plates, by producing a relief on each of them.

In the case of FIG. 1, this relief consists of a simple fold 4 at right angles, positioned at the level of the lower edge 5 of each plate 1, thus conferring an L-shaped section. This fold 4 has a height, or width, between 1 and 2 millimeters, for example. It is sufficient to stop the progression of the tip jî between the two plates 1 by constituting an obstacle or a stop.

The fold 4 is oriented towards the adjacent plate. This fold has a length slightly less than the length of the plate, as shown in Figure 4a. It can also be fragmented or crenellated as shown in fig. 4b.

The type of sheet made up of a juxtaposition of plates, of metallic nature for example, can be used to make protective aprons. These aprons retain a preferential direction of use but, in the event of an error, that is to say if the user positions it upside down, the presence of the fold 4 will avoid any risk of untimely injury.

FIG. 2 represents, still in section along AA, a second embodiment which offers increased security compared to the first embodiment.

Each plate 1 has two folds 4 formed on one face and on the other of the plate, at the level of the two edges 5 and 5 ′ which are opposite. These folds have a height of 1 to 2 mm and a length less than that of the plate. They are oriented towards the adjacent plates and are in one piece or fragmented as shown in fig. 4a and 4b.

It is noted that the folds 4, at a junction of two adjacent plates, are located on either side of the plane of the junction ring 2.

The section of these plates is similar to a very stretched Z or S.

Figure 3 -represented, still in section along AA, a third embodiment of the invention. The plates 1 have two folds 4 formed on the same face; these folds are oriented towards the adjacent plates. The plates have a U-shaped section or bowl. They are preferably arranged opposite one another; they overlap like canal-type tiles constituting a roof. The height of the folds is always 1 to 2 mm for example and their length slightly less than the length of the plates, and these folds are either in one piece, or fragmented or crenellated as shown in fig. 4a and 4b.

We notice, fig. 4b, that the fold 4 consists of two portions 4 'on the edge 5 of the plate and a 4 "portion on the edge 5'. When the plates are assembled, the portion 4" closes the space located between the two 4 'portions. In fact the folds of the opposite edges are complementary.

This particular arrangement of the folds, shown in fig. 4b, with indentations, makes it possible to reduce the weight of the platelets.

The plies shown in Figures 2 and 3 have the advantage of offering the same protection characteristics regardless of their direction of use. We can thus make aprons that can be used in one direction or the other, that is to say front or back and / or head to tail, without distinction, thus offering greater security for the user.

FIG. 4a represents a portion of ply made up with plates according to the third embodiment shown in FIG. 3. These plates 1 have a generally rectangular shape; they can be made of a metallic material, aluminum type, or plastic or fibrous material, of a suitable nature. The ends of the inserts are straight or slightly rounded; they may include a cutaway in the corners 6 or, as shown in fig. 4b, a small cutout 6 'leaving a tab at each end short sides of the wafer. This tab extends approximately from axis to axis.

These plates are adapted, in particular by their holes 3 and the rings 2, to allow a slight overlap between them.

The plates have two folds 4 oriented on the same face. These folds have a height of the order of 1 to 2 millimeters and a length which is slightly less than the length of the plate. The fold stops for example at the right of the inside edge of the hole 3.

The diameter of the holes 3 is of the order of half the diameter of the junction rings 2.

As an indication, the length of the plates can be of the order of five centimeters and their width three times less than said length. The space between two rings of the vertical border is such that it does not allow the point of a knife to pass through.

Longitudinal ribs improve the resistance to bending. There is a rib 7 in the central part, projecting from the same side as the folds 4 and two ribs 8 disposed between the holes 3, projecting from the other side.

FIG. 5 represents, still in section along AA, a fourth embodiment of the plates, in which these plates 1 are highlighted in the form of cylinder segments. The adjacent plates are arranged opposite one another; they overlap there too, like channel tiles used for building roofs.

A sheet made up of these plates according to the fourth embodiment, shown in FIG. 5, has the same advantages as a sheet made up of sheets according to the other embodiments and in particular according to the third embodiment shown in Figure 3.

Indeed, an apron made with this type of tablecloth can be used in both directions, front or back, and / or head to tail, offering the same protection to 1 user.

In this fourth embodiment, the plates have a section in the form of an arc of a circle, the arrow of which corresponds substantially to a quarter of the height, or width, of the plate.

FIG. 6 shows another type of plate which makes it possible to obtain the fifth embodiment of the ply, shown in FIG. 7.

This plate 1 has a generally rectangular shape. Its longitudinal edges 5 and 5 ′ have folds 4 oriented on the same face; its small edges 9 and 9 ′ have folds 10 oriented on the same face as the folds 4. The folds 4 and 10 have a height of the order of 1 to 2 millimeters; they extend over a length slightly less than that of the edges 5, 5 'and 9, 9' corresponding, to release each angle 6. These angles 6 are cut to increase the flexibility of the sheet.

We also note the presence of holes 3 for the passage of the junction rings. Two holes 3 are arranged along the long sides and a single hole in the center, on each of the short sides of the wafer.

To make a sheet, FIG. 7, these plates are juxtaposed by lines and by columns; they overlap each other horizontally and vertically. The adjacent plates 1 are arranged opposite one another on each line and on each column. Thus on the made-up tablecloth, each plate 1 is oriented in the opposite direction with respect to the four plates which surround it and to which it is attached.

The junction rings 2 assemble the plates 1 together; we note that on each column the plates are assembled by rings 2 'arranged vertically; on each line, they are assembled by 2 "rings arranged horizontally.

The overlapping of the plates allows folds 4 and 10 to be on the other side of the plane of the rings junction relative to the body of the corresponding plate; each fold 4, 10 is therefore located in the size of the adjacent plate.

There is shown, Figure 8, schematically, a protective apron made with a sheet of pads as shown in the previous figures.

The folds 4 of these plates are preferably positioned horizontally on the apron, when the latter is worn by the user, as are the generatrices of the segments constituting the fourth embodiment shown in FIG. 5.

An apron made with a ply using plates according to the first embodiment, shown in Figure 1, will consist of plates 1 whose folds 4 will be positioned preferably at the bottom of the plates.

The structure of the plates according to the invention makes it possible to increase their dimension for the preparation of an apron, while increasing protection. This reduces the number of platelets and the number of useful rings; is thus reduced ^{'significantly} the weight of this type of apron.

Fig. 9 shows an apron made from wafers but which also has a sleeve 11 made of chain mail made up of metal rings of small diameter, entangled in each other. This sleeve 11 is produced from a chain mail panel shown in FIG. 10. This panel is assembled on the pads 1 so as to cover the shoulder of the user and in particular the front part, the top, the rear part and most of the arm.

This chainmail is fixed by means of rings on the plates 1. It is noted that the upper part of the deck has an addition of plates 1 to allow the hanging of the chainmail and guide its descent in the back. The sleeve 11 is formed by means of a junction of the angles 13 and 14 of the panel shown in FIG. That is, a junction of the ends of the outer edge of the chain mail panel.

The apron is provided with straps 15 and 16. These straps are crossed on the back of the user.

To this end, the strap 16 comprises, just above its anchoring on the apron, that is to say at the top of the part of the chain mail panels, a loop 17 into which the strap 15 can be introduced.

These straps are adjustable by appropriate conventional means and each have hooks or carabiners at their ends. These carabiners 18 are intended to cooperate with fasteners in the form of rings or the like, 19 positioned on the edges of the deck. Several fixings 19 can be placed on the rim to allow an adjustment of the apron according to the size of the user.
