[0001] The present invention relates to a front post assembly for in-wall frames of retractable
sliding doors.
[0002] Nowadays it is known to provide door frames which involve the use of a casing, positioned
inside a wall, in which a door or a panel is slideably associated and which is also
known as a "retractable door".
[0003] Such solution makes it possible to reduce the encumbrances of the door in a room
thanks to the possibility of sliding it into the casing: thus one can use the space
adjacent to the door, which would otherwise be occupied by doors of the type that
are hinged laterally to a casement.
[0004] In the known art, the frame embedded in the wall is usually constituted by a framework
which comprises a plurality of vertical profiled elements, a front post and a rear
post, which are connected by horizontal crossmembers which define a containment casing
of the panel or of the door.
[0005] Protruding above the case, along an axis that is longitudinal with respect to the
case proper and that extends from the side opposite to that of the containment case,
is a rail which is hidden by a jamb.
[0006] Trolleys coupled to the upper edge of the door are slideably integrated in the rail
in order to enable the sliding of the door into and out of the in-wall casing.
[0007] Usually associated with the end of the rail which is not associated with the vertical
post locators is an additional post that acts as a terminal for the abutment of the
front edge of the door.
[0008] Such conventional door frames thus use metallic profiles that can be mounted together
and are sold for example in kit form for assembly.
[0009] To this end, this applicant is holder of Italian application no.
TV2010A000011 in which an in-wall casing is disclosed for retractable sliding doors, which is characterized
in that at least the crossbeam, the rail, the cross-members, and the spacer can be
cut to measure because reference pre-cuts are provided, and also in which the jambs
comprise at least the crossbeam jamb which can be cut to measure so that the in-wall
casing can be modified at installation time, in order to obtain various different
possibilities for the passage opening, further provided with an adjustable infill
jamb with integrated architraves and a door track that can be adjusted for multiple
door panel thicknesses.
[0010] Although such solution is valid, it suffers a drawback in that the user has to carry
out the centering of the various different components, without which malfunctions
may arise in the sliding of the sliding door.
[0011] This requires time and the use of tools that require, furthermore, a certain level
of skill in the use thereof.
[0012] EP 0 751 275 A2 discloses a wall structure with a sliding door, comprising a perimetral frame consisting
of a plurality of perimetral elements joined together, to the opposite faces of which
there being fixed the wall panels of the structure, between the panels there being
defined a compartment into which the door can slide to be totally contained therein.
Elongate modular elements are associated with the perimetral elements, the modular
elements being in the form of section bars with substantially omega shape and comprising
a central part raised relative to flat lateral portions, the central part comprising
opposing slots to act as means for their fixing to the perimetral element.
[0013] The aim of the present invention is therefore to resolve the above mentioned technical
problems, by eliminating the drawbacks in the cited known art and hence providing
an invention that enables the user to mount components of an in-wall casing of retractable
sliding doors so that they are centered relative to each other, with ease and without
using special tools.
[0014] Within this aim, an object of the invention is to provide a component of an in-wall
casing of retractable sliding doors in which the centering of the various components
can be achieved rapidly.
[0015] Another object is to obtain a solution for centering the elements of an in-wall casing
which can be stable over time, thus keeping the sliding of the door always optimal.
[0016] Another object is to provide an invention that is structurally simple, can be provided
with conventional systems and machines, and is low cost.
[0017] In accordance with the invention, there is provided a front post assemble for in-wall
frames for retractable sliding doors as defined in the appended claims.
[0018] Further characteristics and advantages of the invention will become better apparent
from the detailed description of a particular, but not exclusive, embodiment, illustrated
by way of non-limiting example in the accompanying drawings wherein:
Figure 1 is a perspective view of the front post coupled to the centering element;
Figure 2 shows the front post decoupled from the centering element;
Figure 3 shows the front post placed against the centering element before its coupling.
[0019] In the embodiments illustrated, individual characteristics shown in relation to specific
examples may in reality be interchanged with other, different characteristics, existing
in other embodiments.
[0020] With reference to the figures, the reference numeral 1a, 1b generally designates
a front post for in-wall frames of retractable sliding doors, which is substantially
C-shaped so as to define a first base 2a, 2b, which is preferably but not exclusively
flat, and a first pair of lateral wings 3a, 3b.
[0021] Each front post 1a, 1b has, proximate to a lower end 4a, 4b of the respective first
base 2a, 2b, at least one hole 5a, 5b for coupling, by way of temporary locking means
constituted by a screw 6a, 6b, with a second pair of lateral wings 7a, 7b of a centering
element 8 constituted by a C-shaped cross-member.
[0022] Each one of the second lateral wings 7a, 7b has an end 9a, 9b that arranges itself
against the first base 2a, 2b and is provided with, at least along part of its length,
a substantially V shape, at the vertex 10a, 10b of which there is a seat 11a, 11b
for the threaded shank of the screws 6a, 6b.
[0023] Each one of the seats 11a, 11b is arranged at a height corresponding to the placement
of the axis of the holes 5a, 5b once the edges 12a, 12b of the lower end 4a, 4b of
the first pair of lateral wings 3a, 3b of the front post 1a, 1b are resting on the
second base 13 (which is preferably but not exclusively flat) of the centering element
8.
[0024] The coupling of the front post 1a, 1b with the centering element 8 occurs by way
of the screws 6a, 6b.
[0025] On the second base 13 of the centering element 8 there are guiding means for the
front post 1a, 1b, the means being constituted by L-shaped locators 14a, 14b, a wing
15a, 15b of which protrudes from the second base 13 substantially parallel to the
second pair of lateral wings 7a, 7b and at a distance from the latter substantially
equal to the thickness of the lateral wings 3b.
[0026] This arrangement makes it possible to place the lateral wings 3b against the vertices
10a, 10b of the second pair of lateral wings 7a, 7b of the centering element 8.
[0027] Thus it has been found that the invention fully achieves the intended aim and objects,
a front post being devised for in-wall frames of retractable sliding doors which can
be mounted by the user with ease and without using special tools while performing
a correct, precise and stable centering of the various components.
[0028] The invention is susceptible of numerous modifications and variations, within the
scope of the appended claims.
[0029] The materials used as well as the dimensions of the individual components of the
invention may be more pertinent according to specific requirements.
[0030] The various means of achieving certain different functions certainly need not coexist
only in the embodiment shown, but may be present in many embodiments, even if they
are not shown. The characteristics indicated above as advantageous, convenient or
the like, may also be missing or be substituted by equivalent characteristics.
[0031] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly, such reference signs do not have any limiting effect
on the interpretation of each element identified by way of example by such reference
signs.
