Field of application
[0001] The present invention refers to a tie rod for straightening a door/panel/shutter
and to a method for mounting said tie rod on a door/panel/shutter, according to the
preamble of the respective main independent claims.
[0002] The present tie rod is intended to be employed in the field of production of doors/windows
and in particular of production of wooden doors and similar materials (such as hollow-core
panels or multilayer sandwich of different materials) or even in the field of interior
decoration for producing doors/panels/shutters of furniture pieces, for the purpose
of flattening the profile of the doors/panels/shutters if it no longer has the condition
of planarity, given that it has been warped in an aesthetically and/or functionally
undesired manner.
[0003] The tie rod, according to the present invention, is susceptible of being employed
with doors/panels/shutters of any type, both slidable and shutter, and of any size
in order to correct undesired deformations; in particular, it is advantageously intended
to be mounted on large-size doors/panels/shutters i.e. on doors/panels/shutters produced
with materials and production processes that are inexpensive or in any case unsuitable
for ensuring the non-deformability thereof over time.
[0004] The tie rod, object of the present invention, is therefore generally inserted in
the industrial field of production of doors/windows and in the field of production
of interior decoration articles, i.e. also in the field of production of metal accessories
for doors or furniture pieces.
State of the art
[0005] As is known, in the field of production of doors/windows or of furniture pieces,
the doors/panels/shutters can be warped or deformed over time, assuming a concave
form on an internal or external face of the door/panel/shutter; for example a door
can assume a convexity towards the interior of a room or towards the outside thereof.
[0006] Such deformation, in addition to being aesthetically unacceptable, may compromise
the perfect functionality of the door/panel/shutter, for example preventing a perfect
closure or a perfect sealing on a provided seal of the fixed frame.
[0007] Generally, in the case of hinged doors/panels/shutters, the deformation mainly takes
place at the free edge opposite that constrained, at which the hinges are associated
for connection to the door frame or to the upright of the door/panel/shutter of the
furniture piece, since the hinges oblige at least a partial alignment with such constrained
edge.
[0008] The causes of such deformation are first of all ascribable to the production process
of the door/panel/shutter and to the tensions that start in particular following the
gluing steps, especially if attained with hot pressing and/or with quick production
cycles.
[0009] As is known, for example, the doors for interiors are generally constituted by a
hollow-core panel or by a sandwich composed of: two more external panels, e.g. made
of chipboard, MDF or plywood, by a perimeter frame, e.g. made of solid wood (e.g.
fir, but otherwise also of derivative wood-based materials such as chip) and by a
light honeycomb-shaped structure which is inserted within the frame, e.g. made of
cardboard, as spacer of the two external reinforcement panels of the door. The two
external panels are usually glued on the frame with cold or hot pressing.
[0010] The sandwich thus made is a raw manufactured product which is then covered with very
thin wood sheets or with laminated sheets for making doors of wood or laminate. Otherwise,
the sandwich is directly painted in the various finishes in order to make, for example,
lacquered doors.
[0011] The gluing of the panels to the frame, especially if made with hot pressing, can
involve the generation of internal pressures between the different glued fibers, which
over time lead to the warping of the door/panel/shutter.
[0012] A further cause of deformation of the door/panel/shutter can be traced to the presence
of temperature and/or humidity differences existing between the two sides of the door/panel/shutter.
For example, in the case of an internal door of a home, the internal face of the door
directed for example towards a room can be subjected to environmental conditions different
from that of the external face directed for example towards a hallway or kitchen.
[0013] Such different environmental conditions can involve a different response of the two
faces of the door/panel/shutter, thus with the generation of the above-described undesired
deformation.
[0014] The aforesaid deformation is also encountered quite often in the case of large-size
doors/panels/shutters, in which a small angle of the panel can lead to a large-size
deformation at the center of the door/panel/shutter. Deformations are more easily
encountered also in the case of inexpensive products, i.e. in the case of use of light
materials with low mechanical strength, as in the case of wood seasoned poorly or
for a short time period.
[0015] In order to overcome this drawback, tie rods for straightening the doors/panels/shutters
are widespread on the market; such tie rods are associated in a non-centered manner
with respect to the middle plane or with an internal face or with an external face
of the door/panel/shutter and in a visible position or embedded within the thickness
of the door/panel/shutter.
[0016] Such tie rods consist of a rod which is associated at the ends with two bodies for
engaging the panel of the door/panel/shutter. By acting on a screw/nut screw mechanism
interposed on the rod or associated with the connection between rod and engagement
bodies, it is thus possible to force - by moving apart or approaching - the two engagement
bodies so as to move apart or approach the upper and lower ends of the door/panel/shutter
and consequently act on the position of the plane with which the tie rod is associated,
respectively in order to compensate for a concavity or convexity.
[0017] More in detail, in accordance with a first embodiment of known type, the tie rod
comprises a rod composed of two segments, each associated at a first end with an intermediate
screw / nut screw mechanism and at the other second end with a respective engagement
body embedded in a seat of the panel of the door/panel/shutter. Each segment is axially
engaged with the respective engagement body and is free to rotate with respect to
its axial extension axis. At least one rod segment continues beyond the engagement
body, being accessible with its second free end at the upper and/or lower thickness
of the door/panel/shutter for an easy adjustment. Such second end has for such purpose
an impression for receiving a tool such as a wrench or Allen wrench or a screwdriver
with which it is possible to rotate the rod segment and consequently determine the
screwing or unscrewing of its first end with respect to the screw / nut screw mechanism.
In this manner, the length of the rod subtended between the two engagement bodies
is thus varied, and such bodies consequently exert a thrust or draw action on the
two upper and lower ends of the door/panel/shutter, allowing a return to planarity
thereof.
[0018] In accordance with a second embodiment of known type, the tie rod comprises a rod
made of a single body, which terminates at the two ends with nut screws, each adjustably
engaged by screws whose head is rotatably housed in a seat made of a corresponding
engagement body integral with the panel of the door/panel/shutter. The heads of the
screws are accessible by a milling made in the upper or lower thickness of the door/panel/shutter.
[0019] In this manner, by rotating the head of the screw with a suitable tool, it is possible
to push or pull the two engagement bodies through the rod, such bodies approaching
or moving away from each other.
[0020] Finally, in accordance with a third embodiment, generally employed in association
with doors/panels/shutters of furniture pieces, the tie rod comprises two engagement
bodies embedded in seats made on an internal face, not visible, of the door/panel/shutter
and joined together by a rod which runs on the surface of the of the door/panel/shutter
and is divided into two segments by a screw / nut screw mechanism. The latter comprises
a bush, which is engaged at its two ends to the threaded ends of the two rod segments
and is externally accessible with a wrench in order to be rotated so as to pull or
push the two engagement bodies close to or away from each other.
EP 0 225 312 A2 describes a tie rod according to the preamble of claim 1.
[0021] The tie rods per doors/panels/shutters of known type described briefly above have
in practice shown that they do not lack drawbacks.
[0022] A considerable drawback derives from the fact that the doors/panels/shutters, for
example the doors/panels/shutters for the interior doors, are available on the market
in various models with different sizes, i.e. with length that generally can vary between
about 2 meters and about 3 meters. Therefore, such different sizes of doors require
tie rods with height corresponding to the door model.
[0023] Such circumstance involves the drawback of increasing the production costs and the
storage costs.
[0024] It is known to modify the tie rods by cutting to size - to the desired length - the
rods which join the engagement bodies, in order to adapt them to the specific door
size. Nevertheless, such circumstance involves difficult operations of measuring and
cutting the rod as a function of the length of the door/panel/shutter and depending
on the screw/nut screw mechanism it may be necessary to modify the terminals of the
rod so that it can be associated with the engagement bodies.
Presentation of the invention
[0025] Therefore, in this situation, the problem underlying the present invention is to
overcome the drawbacks of the abovementioned prior art, by providing a tie rod for
straightening a door/panel/shutter which is easily adaptable to the different sizes
of doors/panels/shutters existing on the market, without requiring complex adaptation
operations.
[0026] A further object of the present invention is to provide a tie rod for straightening
a door/panel/shutter, which is simple and inexpensive to attain.
[0027] A further object of the present invention is to provide a method for mounting a tie
rod on a door/panel/shutter which does not require complex and costly adaptations
in order to be mounted on doors/panels/shutters of different size.
[0028] A further object of the present invention is to provide a tie rod for straightening
a door/panel/shutter and a method for the mounting thereof, which are safe and entirely
reliable in operation. Such objects are achieved with a tie rod according to claim
1 and a method according to claim 10.

Detailed description
[0030] With reference to the enclosed drawings, reference number 1 overall indicates a tie
rod for straightening a door/panel/shutter, object of the present invention.
[0031] The tie rod 1 according to the invention is intended to be employed for bringing
back to planarity the panels of doors/panels/shutters of doors or furniture pieces
which - due to environmental or production causes - may have lost the perfect planarity
of their position after their production or even after years.
[0032] Hereinbelow, reference will mainly be made to the preferred application of the present
invention, i.e. in association with a door/panel/shutter 2 of a door, whether it is
of slidable or hinged type, it being intended however that the tie rod according to
the invention can be applied on doors/panels/shutters and walls of different type
such as of cupboards/cabinets, partitions etc.
[0033] The tie rod 1 according to the present invention is therefore generally susceptible
of being employed with doors/panels/shutters of any type, whether slidable or hinged,
in order to correct undesired deformations and in particular it is advantageously
intended to be mounted on large-size doors/panels/shutters or on doors/panels/shutters
produced with materials and production processes unsuitable for ensuring the non-deformability
over time, as can occur for example in the case of hollow-core panels for doors obtained
with multilayer sandwich of different materials.
[0034] The door/panel/shutter of a door 2 (but sometimes also of a furniture piece) generally
comprises a panel 3, for example constituted by a multilayer sandwich, which defines
an internal face 4 and an external face 5, that are parallel to each other and separated
by a thickness S which delimits an upper edge 7, a lower edge 8 as well as two lateral
edges 9, 10, including a first constrained edge 9 connected to the frame of the door/panel/shutter
(or to the upright of the furniture piece) by means of hinges, and a second free edge
10, which is parallel to and opposite the first constrained edge 9 (see figure 12).
[0035] The panel 3 is substantially extended in a mirrored manner with respect to a middle
longitudinal plane P with its two flat and parallel faces equidistant from such plane
(in figure 12 the plane P is indicated with a dash/dot line and its projection on
the thickness S of the panel is indicated with a dotted line).
[0036] The tie rod 1 also comprises, in a
per se known manner, at least two engagement bodies 11, intended to be mechanically embedded
in the panel 3 of the door/panel/shutter 2 in a non-centered manner with respect to
the middle plane P of the same panel 3, i.e. arranged closer to one of the two internal
or external faces of the door/panel/shutter 2.
[0037] In addition, two tie rods 1 are usually provided for each door/panel/shutter arranged
at its two lateral edges 9 and 10.
[0038] The tie rod 1 also has at least one rod 12, provided with a main extension that is
substantially axial Y, which is axially mechanically connected at its first ends 13
to the two engagement bodies 11.
[0039] Screw / nut screw means 14 are then provided for lengthening and shortening the length
of the rod 12 subtended between the two engagement bodies 11, in order to adjust the
tension of the tie rod and consequently straighten the door/panel/shutter.
[0040] According to the idea underlying the present invention, the rod 12 comprises at least
one first and one second rod segment 12A, 12B, which are provided, for the length
of corresponding first and second sections 15A, 15B of their axial extension, with
respective first and second shaped profiles 16A, 16B, which are mechanically couplable
with each other with shape coupling for a variable shared section 17.
[0041] Then, by varying the length of the shared section 17 which couples the shaped profiles
16A and 16B of the two rods 12, it is easily possible to adjust the overall axial
length of the entire rod 12.
[0042] This allows making rod segments 12A, 12B equivalent to each other (for example about
1.30-1.50 m), which can then be differently connected to each other in order to obtain
tie rods susceptible of being employed for all door sizes.
[0043] This particular technical feature is extremely advantageous, allowing the production
of a single component, i.e. of a single rod segment still capable of satisfying the
different application requirements of the clientele, and consequently also allowing
storing only such component since in fact the two rod segments are advantageously
fully identical to each other. Consequently, the tie rod, object of the present invention,
allows a considerable reduction of the production and storage management costs of
its components.
[0044] More clearly, by coupling the two segments together, for example arranging a very
short shared section, a tie rod is obtained that is very long for very high doors,
for example up to 3 meters; by coupling two tie rods, arranging a very long shared
section, a tie rod is thus obtained that is very short for very low doors, for example
with 2 meters height.
[0045] After having associated the tie rod 1 with the panel of the door/panel/shutter 2,
in a manner
per se known as better specified hereinbelow, it will be possible to actuate the screw /
nut screw means 14 for adjusting the length of the rod 12 subtended between the two
engagement bodies 11 and hence cause a moving-apart thrust action between the engagement
bodies 11, aimed to eliminate a concavity on the face of the panel 3 carrying the
engagement bodies 11 associated therewith, or for determining an approaching pull
action of the engagement bodies 11, aimed to eliminating a convexity on the face of
the panel 3 carrying the engagement bodies 11 associated therewith.
[0046] The first and the second shaped profiles 16A, 16B advantageously alternate the shape
of a male element 16' with the shape of a female seat 16", along the axial extension
Y of their respective first and second sections 15A, 15B.
[0047] The male elements 16' of the two shaped profiles 16A, 16B are inserted in the female
seats 16" of the other facing shaped profile 16A, 16B in order to render the two segments
12A, 12B of rod 12 (see figures 1 and 2) axially integral.
[0048] For example, the pitch R between the male elements 16' or between the female seats
16" can be 10 mm such that the length of the rod can vary at intervals of 10 mm and
be able to form, with two rod segments 12A, 12B of about a meter and a half each,
tie rods for doors with height comprised between 2 meters and 3 meters.
[0049] The form of the shaped profiles 16A, 16B - i.e. of the male elements 16' and of the
female seats 16" - can be quite varied, able to provide for sawtooth or lobe solutions
as in the case illustrated in the enclosed figures.
[0050] In accordance with a preferred embodiment of the present invention, the two shaped
profiles 16A, 16B define, in the shared section 17 in which they are coupled, a cross
section which is substantially unchanged with respect to that of the parts of rod
segments 12A, 12B in which the shaped profiles 16A, 16B are not present.
[0051] In this manner, the provided milling made in the panel 3 (described hereinbelow),
which serves to maintain - assembled and guided - the two rod segments 12A, 12B with
the shaped profiles 16A, 16B coupled together for the shared section 17, can be made
with regular shape for the entire distance that separates the seats in the panel of
the door/panel/shutter for the two engagement bodies 11.
[0052] Advantageously, for this purpose, the rod segments 12A, 12B have the form of elongated
plates with the sections bearing the first and the second profile 16A, 16B with reduced
width. In this manner, such elongated plates of the two rod segments 12A, 12B define
in the shared section 17, in which the two shaped profiles 16A, 16B are coupled, substantially
the same cross section that the elongated plates of the rod segments 12A, 12B define
in the sections lacking the corresponding shaped profile 16A, 16B.
[0053] Consequently, the lateral edges of the rod 12 are substantially parallel for their
entire axial extension such that the milling on the panel is correspondingly constituted
by a groove with width and depth equal to the width and thickness of the rod 12.
[0054] In this manner, the first and the second shaped profile 16A, 16B of the rod segments
12A, 12B are susceptible of being retained coupled with their shared section 17 which
actually constrains them, within the groove obtained flush on the panel 3 of the door/panel/shutter
2.
[0055] The screw / nut screw means 14, mentioned above, comprise at least one screw 19 (see
figures 3 and 4) provided with a shank 19', engaged in a nut screw 20 constrained
to at least one first end 13 of a rod segment 12A, 12B, and with a head 19" rotatably
housed in a seat 21 made in a corresponding engagement body 11.
[0056] Advantageously the engagement bodies 11 are obtained in a pressure die-cast body
made of zamak with the seat 21 for the head 19" of the screw which is continued with
a neck 22. Within the latter, the initial part of the shank 19' of the screw 19 is
housed. Preferably, the body made of zamak of the engagement body 11 also comprises
a semi-annular seat 22' side-by-side the seat 21 in order to support the shank of
the screw 19 in a rotatable and axially centered manner.
[0057] In accordance with the preferred embodiment of the present invention, the screw/nut
screw means 14 also comprise a bush 23, which is fixed to the first end 13 of the
rod segment 12A, 12B and bears, obtained at a termination axially directed towards
the engagement body 11, the aforesaid nut screw 20.
[0058] The bush 23 is advantageously made of metal and is fixed for example by means of
a weld to the first end 13 of the relative segment 12A, 12B of rod 12 with the axis
of the bush 23, i.e. the axis of the nut screw 20, parallel to the axial extension
Y of the rod 12.
[0059] The milling 32 on the panel is extended up to reaching the upper and/or lower edge
7, 8 of the panel 3 of the door/panel/shutter 2 in order to allow the access with
a tool U to the head 19" of the screw 19 and hence to be able to rotate and thus cause
the tightening of the panel 3, bringing it back to planarity if an undesired deformation
thereof has occurred.
[0060] Also forming the object of the present invention is a method for mounting the above-described
tie rod on a door/panel/shutter 2, regarding which the same nomenclature introduced
up to now will be maintained hereinbelow for the sake of description simplicity.
[0061] The method provides for an initial step of arranging a panel 3 of a door/panel/shutter
2 composed of a sandwich formed by at least two external parallel laminar layers 30
(e.g. made of MDF) with a perimeter frame 31 (e.g. made of solid wood, such as fir)
interposed therebetween.
[0062] Within the frame 31, a honeycomb-like filler material 35 could for example be inserted,
which is very light and susceptible of giving structure to the door/panel/shutter
2.
[0063] Initially, at least one of the two external laminar layers 30 is separated from the
remaining sandwich structure part of the panel 3, i.e. it is separated from the frame
31.
[0064] More in detail, the perimeter frame 31 of the panel 3 is provided with two parallel
uprights 31A and with two parallel crosspieces 31B which are joined to the uprights
at the respective ends in order to form the frame 31 in the shape of a quadrangular
frame, in particular rectangular frame.
[0065] On the faces directed towards the outside of the two lateral uprights 31A, two corresponding
shaped millings 32 (see figure 9) are made, which have, in vicinity to the upper and
lower ends of the uprights 31A (i.e. in vicinity to the upper and lower edges 7, 8
of the panels 30), two seats 33 for housing the engagement bodies 11. Such seats 33
are separated from each other by a first distance D1 (figure 9) and are connected
together by a groove 34 that continues beyond at least one of the two seats 33 (and
preferably beyond both seats 33) up to a corresponding upper or lower edge 7, 8 of
the panel 3, in order to render the seat 33 of the engagement body 11 accessible from
the edge of the same panel 3 (hence through a terminal milling) for example by means
of a screwdriver, a wrench of another tool. The groove can have different depths in
order to house the flat sections of the rod segments 12A, 12B and the sections at
the first ends 13 in which the bushes 23 are fixed below.
[0066] At this point, it is possible to couple together the two segments 12A, 12B of rod,
adjusting the length of the shared section 17 of the shaped profiles 16A, 16B, in
a manner such to space the engagement bodies 11 by a second distance D2 equal to the
first distance D1 between the seats 33 on the frame 31 of the panel 3 of the door/panel/shutter
2.
[0067] Subsequently, the tie rod 1 thus assembled is inserted in the milling 32 with the
rod 12 composed of the two coupled segments 12A, 12B (and of the two bushes) which
is flush-inserted in the groove 34 of the frame 31 of the panel 3 and with the engagement
bodies 11, axially mechanically connected to the first ends 13 of the rod 12, which
are flush-inserted in the seats 33 of the milling 32 of the frame 21.
[0068] It is therefore possible to fix the laminar layer 30, which was separated from the
panel 3, to the frame 31 in order to thus form the sandwich and close the milling
32 with the tie rod 1 therein and in particular with the rod 12 guided and closed
within the groove 34.
[0069] As indicated in the enclosed figures, two tie rods 1 are provided for each door/panel/shutter
2; nevertheless, even only one tie rod could be employed, or more than two tie rods
could be employed, such as three tie rods, including two placed at the lateral edges
9, 10 of the door/panel/shutter 2 and one placed at the center of the door/panel/shutter
2.
