Abstract

Device for assembling surfaces by the alternate double insertion of pins, bars or cables in housings or channels which already exist or which are made in the said surfaces.

Description

DISISSITY of AS LIFLADE from SUAFALES by INSERTICK from AXES in LUGE @@ NTS
Preliminary presentation.De@inition of accommodation, canoux, etc. A surface can include cbd channels for housings, which can be made in the same thickness of said surface, and capable of receiving exes, bars, cables, etc.

If it is a fabric, possibly three-dimensional, the canies can be obtained during the same weaving, without welding, neither sewing, nor collageextrusion.etc.If it is another kind of surface: non-woven, plastic, or other, the methods for obtaining the above-mentioned channels can be used (see lines 7 and @.) The dimensions of the channels and their spacing are chosen according to the solutions sought. instead of mentioning these hollow edges (fig 4)
The reaction of a surface with housings can between described as follows: if a rigid bar is introduced into a housing, at the ends of which a traction perpendicular to the axis of the housing, the axis is wedged at the edge of said housing, in the direction of traction.

 The invention consists in using this blocking effect flush with a housing, it being specified that 12 tensile force is thus exerted over the entire portion of the surface in contact with the bar.

In the case of a fabric, all the threads tangent to the axis undergo the tensile force and therefore work. This is not the case when the connection is made by sewing, rivets, etc.

The main use envisaged is the reading of two surfaces A and B comprising housings, preferably identical and superimposable, and located along or in the vicinity of the line of approximation. We thus have two housings, generally parallel, and uses for each D @ them the effect of blocking by traction, being specified that the bars or axes exert their action simultaneously and alternately in the two housings - (Figure 1) a first system of establishment, not exclusive, consists in defining on each housing successive, identical and superposable segments.

The segmentation can in particular be identified by tracing, or by the introduction of a fine point which maps the threads without breaking, therefore without any resistance. In the case of nonwoven, plastic or other surfaces, the location of these rep @ res, see through holes, can be defined by any process.

Or by cutting, total or partial, areas of separation between segments. This done we superbly place the housings and to make the connection we introduce an element (axis, cable bar etc from the first segment of A. See fig
S- (1) the cable is shown in white.

then at Point P @ we cross the tangent faces of A and B. The cable shown in white arrives in the PO / PI segment of B which it follows up to point P1.

This white axis crosses the two tangent faces at point PI and arrives in segment P1 / P2 of A.

It follows it up to point P2 and goes back into segment P2 / P3 of B and so on until the last segments.

Then, or simultaneously, we thread, symmetrically a second axis or cable, shown in black. If we tend to move the surfaces A and
B. cables, axes, bars, etc. are drawn towards the inside edge of the housing located on the side of
The other wall, where they get blocked.

FIG. 1 represents the alternating penetration of the connecting elements in the channels or housings of surfaces A and B. FIG. 2 represents the connection when the two surfaces are intended to follow one another in the same plane. (Conveyor belts, geotemetic surfaces, tarpaulins, boat sails, runways or landing strips, etc.
FIG. 2 represents the momentary superposition on the same side of the line of the ison of surfaces intended to be perpendicular to one another or oblique (volumes, containers, gabions, tarpaulin angles, tanks, etc.

Figure 4 shows the special case of lai son by joining hollow edges.

EFFICIENCY and EFFICIENCY of the process. Once the connection is made and the exes, bars, cables, definitively
MENT blocked, we see that there is practically no loss of linear resistance, as indicated in lines 22 to 29. In addition we can see in the figures, and in particular in Figure I that no element of lisison is only visible on the surface.

These elements are therefore protected from any external attack such as friction, UV radiation (which allows the use of aramid halyards without special protection.)
This, taking into account the loss of linear resistance generally resulting from conventional assembly means, makes it possible to lighten the textures which are generally calculated as a function of the final resistance sought, in particular in the approximation zones.

MODES OF USE

Ex 1. WALLS INCLUDING CROSS-HOUSING HOUSING; the nearest housing is used on each side of the connection line, unless a covering effect is sought (conveyor belts, geotextiles, etc.)
Ex 2 Walls have longitudinal housings, in particular hollow edges. The assembly is done according to Figure 4.If you want to be able to fold in an accorion, facilitating transport, use the device 3.If the longitudinal channels are relatively distant from the edge of the surfaces -cases of the longitudinal housings made at a certain distance from the edges on looms without shuttle, devices 2 or 3 are used
Ex. 3. Wall simultaneously comprising transverse housings, longitudinal housings and hollow edges (or only two of these elements) all combinations are possible. Hollow edges or longitudinal housings can be used for lateral connections. for various purposes, the transverse housings: Longitudinal connections insertion of load-bearing devices (slats, etc.) for raceways, raceways, and also external maintenance cables.

Likewise in windbreak jobs, etc.
OTHER DEVICES. Apart from the axes, bars, and:, it is recalled that the invention consisted in the use of the blocking effect which occurs, during a perpendicular pull, along one of the edges of the housing or canals.

Another method of using this blocking effect consists in introducing into each of the two housings concerned a set (flat bar and accessories) comprising connecting devices between bars placed at a suitable distance, and such as cable passages , housing hooks, rings etc, or combinations of elements, connected to the bar but outside the housing, and likely to be connected together. We thus obtain the log of each housing a series of external devices hanging, with an additional overlap if necessary.

SIMPLIFIED DEVICE. We insert an axis, bar, been in each of the interested homes, we superimpose them and we make one or two pledges. Therefore, as indicated in lines 22 3 29 all of the interested areas work.

Walls with very high resistance. For surfaces, in particular in aramid, which reach resistances of more than 100 T per linear miter, the device described above is particularly advantageous. As cables we can use a halyard in KhVLAR (brand registered DUPONT de NEMOURS)
