Multiple strips doors

A door composed of multiple strip of the type comprising a support with hooks and strips provided with means for hooking to said support, wherein the support takes the form of a channel whose transverse section is in the form of an inverted C, in the base of which are arranged hooks known per se whose ends constitute a guide with the corresponding edge of the channel with a view to receiving a panel which closes the hooks.

The present invention relates to improvements in doors composed of multiple 
strips and more particularly to the fixing of the strips with respect to 
the cross bar from which they are suspended. 
Certain of the strips of the doors in question may be deteriorated upon 
passage of handling vehicles or gear, and should be able to be replaced 
without having to dismantle all the strips. Due to the conventional 
constitution of these types of doors, it is generally not a rapid nor an 
easy operation to dismantle and re-assemble separate strips. 
Furthermore, it is often required to remove all or part of the strips of a 
door when the weather is very hot, in order to improve ventilation of the 
premises closed by this door. This operation is difficult to carry out 
with the conventional assembly of the strips. 
It is an object of the improvements forming the subject matter of the 
present invention to remedy these drawbacks and to enable a door composed 
of multiple strips to be produced of which each strip comprises means for 
dismantling it easily without this being prejudicial to its pivoting.

Referring now to the drawings, FIG. 1 shows the upper part 1a of one of the 
strips 1 of a door comprising the improvements according to the invention. 
This part of each strip is provided with perforations 1b disposed parallel 
to its upper edge. 
To each strip 1 there corresponds a plate 2 provided with loops 2a which 
project outwardly perpendicularly from one of its vertical faces and whose 
shape is such that they may engage in the perforations 1b of the strip 1. 
The height of the loops is such that once the strip is applied against the 
face of the plate from which these loops extend, it is possible to engage 
a pin 3 therein. All the pins are connected by a bar 4 so as to constitute 
a sort of comb. It will be observed that the pins 3 are bent so that they 
have a certain elasticity allowing an excellent fastening of each strip 1 
with respect to its plate 2 as they are tightened against each other. 
Each of these plates 2 is provided with perforations 2b in which are 
engaged hooks 5 arranged in a channel 6 intended for supporting the strips 
whilst facilitating their pendular motion. 
The transverse section of the channel 6 is generally in the form of an 
inverted C (FIG. 2) whose base is in the form of parallel hooks 5 which 
are spaced apart from one another by a sufficient distance for the plates 
2 not to be too perforated in order to conserve a good mechanical 
strength. The origin of each hook forms part of the vertical face 6a of 
the channel whilst its useful part which engages in the corresponding 
perforation 2b of the plate 2 is deformed outwardly in order to constitute 
a leg 5a which is bent at an obtuse angle. The free end of each hook is 
folded so as to constitute an edge 5b divergent with respect to the 
opening 6b of the channel. The edge 6c of the latter which runs along said 
opening 6b is turned upwardly to constitute, with the edge 5b of each 
hook, a dovetail guide. Fixing holes 6d, 6e are provided, intended to 
enable the door according to the invention to be suspended below or on the 
side of the lintel of an opening or passageway. 
As shown in FIG. 2, once the plates have been associated with the strips 1 
due to the use of the bar 4, the hooks 5 are engaged in the perforations 
2b of said plates with the result that the strips are suspended from the 
channel 6 so that they may easily make a pendular motion as the upper edge 
of each of these perforations 26 rests in the angle of the bent leg 5a of 
the corresponding hook 5. 
To avoid the plates 2 being disengaged from the hooks 5 as a result of too 
great a displacement of certain strips 1, the guide constituted by the 
edges 5b of the hooks 5 and the edge 6c of the channel 6 are provided to 
cooperate with a panel 7 of which the longitudinal sides 7a, 7b are 
suitably folded down. This panel moves axially with respect to the guide 
to allow a plate 2 to be disengaged with a view for example to replacing a 
strip 1. It may be designed to fit by the elasticity of the elements. 
A door is thus produced whose strips are rapidly and easily mounted on the 
suspension system which, furthermore, offers each strip an excellent 
amplitude whilst preventing it from becoming unhooked.
