[0001] The invention relates to a peripheral supporting framework for doors of inhabited
buildings, made with such constructive characteristics as to allow each door to be
supported on a condition aligned with the same framework.
[0002] At the present time, the doors of inhabited buildings are assembled on to a peripheral
framework secured into the openings of the walls of the same buildings, to which the
hinges for supporting the doors are fixed, which hinges permit the doors to be opened
and closed. Such peripheral framework is constituted by a front vertical edge covering
plate, a back vertical edge covering plate and an upper horizontal front edge covering
plate and an upper horizontal back edge covering plate, which are joined together
by a central case in which the door is mounted, and between the case and the vertical
and horizontal edge covering plates there are delimited a front and a back peripheral
edge, which are re-entering with respect to the relative peripheral edge covering
plates.
[0003] With this structural configuration of the door and framework, therefore, the framework
is surrounded from both sides by such peripheral edge, which cannot be eliminated
and is always visible in any position in which the door is displaced, while the side
opposite to the side in which the door is supported is shaped with a discontinuous
surface, and in this way the assembly framework-door hasn't an uniform aesthetical
appearance.
[0004] The object of the present invention is to overcome these drawbacks, by eliminating
the presence of said peripheral edges and the discontinuous surface, and by providing
a peripheral supporting framework for doors which is so shaped as to cover the peripheral
edge on both sides of the framework and to obtain a continuous surface on the side
opposite to that in which the door is supported, thereby conferring an uniform and
agreeable aesthetical appearance to these component parts. This peripheral framework
is made with the structural characteristics which will be described, with particular
reference to the attached claims of the present patent.
[0005] The invention will be better understood from the following description, given by
way of not limitative example and with reference to the accompanying drawings in which

[0006] The above mentioned Figures schematically represent a peripheral supporting framework
5 for doors of inhabited buildings, which is secured into the openings of the walls
of the same buildings, for supporting the door 6 and allowing the same to be opened
and closed.
[0007] As visible from the Figs. 1-3, the peripheral framework 5 is formed by a set of component
parts, which will be described in detail, and are shaped in a manner to determine
two plane vertical side edge covering plates 7 and 8, parallel and spaced away from
each other of an extent slightly larger than the wall thickness, and constituted respectively
by a front vertical edge covering plate 7 and a back vertical edge covering plate
8, by a central case 9 for joining the edge covering plates 7 and 8 and by two upper
horizontal plane edge covering plates 10 and 11, parallel and spaced away from each
other like the preceding edge covering plates and also constituted by a front horizontal
edge covering plate 10 and a back horizontal edge covering plate 11, joined to each
other always by a central case 9, of which the front side edge covering plates 7 are
extended around the door vertical sides for a height greater than that of the same
door and have almost the same width, while the front upper edge covering plate 10
and the back upper edge covering plate 11 are extended horizontally around the door
upper side and have a height equal to the width of the side edge covering plates 7
and 8, and the assembly upper edge covering plates 10, 11 - case 9 is joined at the
upper side to the assembly side edge covering plates 7, 8 - case 9. In turn, the door
6 is supported by hinges (not indicated) fixed to the case 9, in such a manner that
the door outer surface is perfectly aligned for the entire extent thereof with the
outer surface of both the front side edge covering plate 7 and the corresponding upper
front edge covering plate 10, while on the opposite side of the framework 5 such door
be re-entering with respect to the outer surface of the back side edge covering plate
8 and the corresponding upper back edge covering plate 11 of the same framework.
[0008] Turning now to the Fig. 4, in which the framework 5 is shown, and to the Figs. 7-9
in which several component elements of the same are shown, it is noted that the front
side edge covering plate 7 where the door is mounted is shaped with a rectilinear
portion 12 having a determinate length and a limited thickness, the inner side of
which is provided with a longitudinal hollow 13 adaptable along one of the side edges
of the opening of the wall of the building and a blind hole 14, in which a dowel 15
or other suitable fixing means is insertable for coupling with the central case 9
as it will be described. Moreover, the back side edge covering plate 8 is shaped with
a rectilinear portion 16 parallel to the rectilinear portion 12 of the previous edge
covering plate 7, having a determinate length and a limited thickness, the inner side
of which is also provided with a hollow 17 adaptable along the other edge of the opening
of the wall of the building, said rectilinear portion being in turn joined to a projection
18 bent orthogonally with respect thereto and adapted to be coupled as it will be
described with the central case 9 of the framework 5 (see also Fig. 7).
[0009] Finally, the central case 9 is shaped, on the side in which the door 6 is mounted,
with a plane peripheral recess 19 having parallelepiped form, and a vertical gasket
20 is fixed against this side for the entire height of the door, by means of a dowel
21 inserted into a corresponding blind hole 22 of such recess, in order to allow the
abutment of the relative inner surface of the door displaced in the closed position
thereof. In particular, this recess 19 is so dimensioned that when the door 6 is displaced
on the closed position thereof its outer surface is aligned with the outer surface
of the front side edge covering plate 7, and the door side is arranged close with
respect to the opposite side of the recess 19 and the side edge covering plate 7,
thereby defining a side slit 23 with reduced thickness, under the condition in which
also an almost continuous outer surface is defined, which is formed by the side edge
covering plate 7 and the closed door, which confers an agreeable aesthetical appearance
to these component parts. This side of the central case 9 is further shaped with a
side hollow 24 for inserting the dowel 15 therein and into the blind hole 14 of the
front edge covering plate 7, with consequent coupling of this latter with the same
central case.
[0010] On the side opposite to the side in which the door 6 is mounted, the central case
9 is also shaped with a hollow 25 for inserting the projection 18 of the back side
edge covering plate 8 (see Fig. 9), with consequent coupling of these two component
parts. Such projection may be inserted with different depths into the hollow 25, thereby
changing of a certain extent the distance between the two edge covering plates 7 and
8, and permitting in this way the adaptation of the framework to walls having different
sizes, without the need to use a specific framework for each wall having a determinate
size. The back side edge covering plate 8 is made with an outer surface having rectilinear
form, and its outer profile is always aligned with the outer profile of the central
case 9, for any adjustment position of the distance between the two edge covering
plates 7 and 8, thereby determining again a continuous outer surface with the framework,
even in the passage port, without the presence of steps or edges. Finally, in the
Fig. 6 there are shown the sole back upper edge covering plate 11 and the side vertical
edge covering plates 7 and 8 and the relative case 9, which are always identical to
the corresponding preceding component parts, except the back upper edge covering plate
11, the projection 18 of which is made longer than its rectilinear portion 16, in
a manner that its end portions are protruded with respect to the same rectilinear
portion, and that during the joining of these horizontal component parts with the
vertical component parts such protruded end portions may be arranged on to the corresponding
projections 18 of the vertical component parts, without determining any gap between
the so joined parts.
