Description
The partitions forming the object of this invention comprise
substantially a strengthening structure consisting of an assembly
of uprights and crosspieces made of extruded box-like sections of
metal or a light alloy. The spaces defined by said assembly are
provided with opaque, translucent or transparent panels in any
suitable material.
This invention relates to the whole partition as described
hereafter. It relates also to the particular elements. These
particular elements are namely the device for assembling the
uprights and the crosspieces as well as each of the elements making
part of the said assembly and characterized, for each of the
latter, by an upright, a cross-piece, the engaging lock device with
its resilient element and its blocking stop together with all the
complementary elements such as butt straps, inserts and sound and
thermal insulating means.
The object of this invention is to provide such double-walled
partitions having a very high stability which are rapidly and
conveniently mounted and dismantled.
Another object of this invention is to provide, for assembling the
uprights and the crosspieces, strong elements which are very
readily and economically manufactured at the industrial scale.
Another object of this invention is to provide such assemblies in
which the various constituting parts are prevented from being
accidentally dislocated or separated.
These various objects are obtained by the fact that a double
partition according to the invention comprises a strengthening
structure formed with uprights and crosspieces consisting of
extruded box-like sections generally divided into three
compartments, the two extreme compartments being longitudinally
opened, while the uprights and the crosspieces are connected
through a lock having a perforated body and forming a housing for a
V-shaped spring blade and a rotating and removable stop on which
bears one of the legs of the said spring blade, the said stop
bearing itself on the section which it engages, the partition being
completed by filling panels maintained in their positions by butt
straps made integral with the said strengthening structure through
inserts of a material forming a thermal and sound insulation.
It should be namely pointed out that all the main parts such as the
box-like sections of the uprights and the crosspieces, the lock,
the butt straps and the inserts may be made by rapid and economical
industrial extruding means.
More particularly, it should be noted that the lock having a
relatively intricated shape is made by extrusion from an extruded
section which is subsequently severed at intervals determined in
accordance with the width.
Of course, these various constituting elements may be made under
varying shapes and sizes generally determined by the nature of the
partitions and walls being made.
Thus, an embodiment will be described hereafter with more details
only by way of example and without any limitation, reference being
made to the enclosed drawings in which:
FIG. 1 shows an exploded view of the constituting elements of an
assembly of uprights and crosspieces;
FIG. 2 shows a perspective view of the elements of FIG. 1 after
assembly;
FIGS. 3 and 4 are sections on the lines III--III and IV--IV of FIG.
2, respectively;
FIG. 5 shows a perspective view of a portion of the partition
according to the invention;
FIGS. 6 and 7 are sections on the lines VI--VI and VII--VII of FIG.
5, respectively.
In this embodiment, the uprights and crosspieces are elements
having the same profile and the same transverse dimensions. These
uprights and crosspieces 1 and 2 respectively consist of box-like
sections divided namely into three compartments 3-4-5, the central
compartment 3 being completely closed, while the compartments 4-5
are opened, the outer face thereof comprising two flanges 6-7 the
longitudinal free edges of which are parallel and separated by a
distance D.
Upon each of said two solid faces, the said sections have outwardly
and inwardly a pair of ribs 8-9, 10-11, 12-13 and 14-15
respectively. The outer ribs 8-9 and 10-11 have outlining free
edges profiled to form catching elements.
A lock 16 comprises a part having a uniform thickness D1 which is
slightly smaller than the distance D of the sections 1-2 as well as
smaller than the distance D2 separating the pairs of inner ribs
12-13 and 14-15 respectively. The said part has a body 17 under the
form of a frame extended, on one side, by a head 18 the front face
of which has a central cross rib 19. The said head 18 is bonded
with the said body 17 so that two deep notches 20-21 remain between
the said two constituting parts of the lock, the thickness D3
separating the bottoms of the said notches being smaller than the
said distance D. The back faces of the head 18 have each a shoulder
22-23 respectively, the width of which is substantially equal to
the thickness of the flanges 6-7 of the sections 1.
The uprights of frame 17 are preferably bevelled as shown in FIGS.
1, 3 and 6.
At the level of the crosspieces, in the bottoms of the extreme
compartments 4-5, the uprights 1 have a hole 24 the diameter of
which is slightly greater than the thickness D1 of lock 16 and more
particularly greater than the width of the front rib 19 of the said
lock.
The spring element 25 comprises namely a U-shaped steel blade the
side legs of which have different lengths. The width D4 is greater
than the thickness D1 of lock 16 which is slightly smaller than the
width D5 of the central compartment 3 of the section 2. The overall
height D6 is equal to or very slightly lower than the height D7 of
the space 26 of the frame 17, whereas the overall width D8 of the
said spring 25 is equal to or greater than the width D9 of the said
space 26 defined by the frame 17.
The rotating and removable stop 27 comprises namely a length of a
cylindrical bar having a large flat portion 28.
The length D10 is slightly smaller than the width D11 of the
crosspiece.
The said crosspieces have, at suitable locations in the bottoms of
the two extreme compartments 4-5 and opposite to the longitudinal
openings, holes 29 the diameter of which is very slightly greater
than the diameter of the said stop 27.
In order to assemble the uprights 1 and the crosspieces 2, the
following steps will be sufficient: engaging the spring 25 with the
frame 17 of the lock 16, engaging the rear portion of the lock 16,
with the central compartment 3 of the corresponding end of a
crosspiece, engaging the stop 27 with the corresponding hole 29 so
that the smallest transverse dimension thereof is interposed
between the shortest leg of the spring 25 and the adjoining wall of
the lock frame 17, bringing the crosspieces at the level of the
corresponding hole 24 of the upright by introducing the head 18 of
the lock between the flanges 6-7 of the upright, the head rib 19
engaging the said hole 24, rotating the crosspiece with its lock on
90.degree. and finally rotating the entire stop 27 about the axis
thereof, which may be made through a simple tubular wrench the
cavity of which fits to the shape and the transverse dimensions of
the said stop.
The partition is completed by the suitable panels or panes 30
maintained with butt straps 31 which in turn are fastened to the
uprights and crosspieces through inserts 32 of a material having a
small thermal and acoustical conductibility.
The invention relates as well to the partitions as to the
characteristical elements forming them.
