Abstract
Description
- The present invention generally finds application in the field of heat and sound insulating devices for doors and windows, and particularly relates to an anti-water seepage system for a door or window with no raised threshold.
- Systems have been long known to be installed in the door or window leaves, to prevent water seepage between outside and inside environments.
- These systems are provided in different forms depending on how the doors/windows are to be closed and the position thereof with respect to the outside environment.
- Generally, these systems include seals that are fitted into seats formed in the side and bottom edges of the leaf and are adapted to abut the uprights of the frame and a raised threshold installed at the floor or ground, respectively.
- For proper operation, the seals must be as long as the edges of the door/window and must have a high sealing capability under water pressure.
- Nevertheless, these seals cannot prevent massive water seepage and are not easy to install, especially at the corners of the leaf.
- A further drawback is that the raised threshold is a critical element in such systems, but also constitutes an architectural barrier for handicapped people who shall access the inside environment to through the opening of the door/window.
- In order to at least partially obviate these drawbacks, sealing systems have been developed, which comprise draught-excluder devices secured to the bottom edge of the leaf and acting in combination with seals installed on the uprights of the door/window frame.
-
WO2008152664 discloses an anti-water seepage system comprising an automatic draught-excluder device with a seal that can be automatically lowered to block the space between the leaf and the threshold. - In addition, the system comprises a pair of seals installed on the uprights of the frame and acting on the leaf and the draught-excluder to block the space between the jamb and the leaf when the latter is closed.
- A first drawback of this arrangement is that the pair of seals only partially acts on the draught-excluder device by creating a barrier against water seepage whose height is equivalent to that of the device.
- Therefore, this system can only block water columns against the door/window, that have a small height.
- A second drawback of this arrangement is that the seal in the draught-excluder device has an geometry that can only partially prevent water seepage toward the interior of the device.
- Another common drawback of this arrangements is that the seal does not entirely conform the profile of the threshold in case of uneven flooring, which will affect the sealing effect on the entire system.
- In light of the prior art, the technical problem addressed by the present invention is to provide a system for a door or window with no raised threshold that can effectively block water seepage and ensure a stable sealing effect over time.
- The object of the present invention is to obviate the above drawback, by providing an anti-water seepage system for a door or window having no raised threshold that is highly efficient and relatively cost-effective.
- A particular object of the present invention is to provide a device as described hereinbefore that can prevent massive water seepage.
- A further object of the present invention is to provide a system as described hereinbefore that can block seepage caused by water columns having different heights and in any case greater than the height of the draught-excluder device.
- Another object of the present invention is to provide a system as described hereinbefore that can block seepage without using raised thresholds.
- A further object of the present invention is to provide a system as described hereinbefore that can be installed in doors and windows of different types.
- Another object of the present invention is to provide a system as described hereinbefore that can be simply manufactured and maintained.
- Yet another object of the present invention is to provide a system as described hereinbefore that does not alter the exterior appearance of the door or window on which it is installed.
- The above mentioned purposes, as well as others that will be more clearly explained hereinafter, are fulfilled by an anti-water seepage system for a door or window with no raised threshold, as defined to in
claim 1, wherein the shutter comprises a leaf with a substantially horizontal bottom edge and a pair of substantially vertical side edges and a frame with a pair of substantially vertical uprights. - The system includes a draught-excluder device mounted along the bottom edge of the leaf and having a box-shaped body defining a longitudinal axis and a first seal associated with the box-shaped body and adapted to vertically move from an idle lifted position to an operating lowered position in contact with the ground.
- In addition, the system comprises a pair of substantially vertical extension elements which are adapted to be mounted to the side edges of the leaf and a pair of second substantially vertical seals adapted to be mounted to the uprights of the frame. The box-shaped body, the first seal in the lowered position and the extension elements have respective abutment surfaces for the second seals when the leaf (L) is in the closed position and its side edges face the uprights.
- According to a peculiar aspect of the invention, the extension elements are placed on top of the box-shaped body and the first seal and form an assembly therewith, whose total height is greater than the height of the draught-excluder device and substantially equal to the height of the second seals to form a raised threshold therewith and prevent water seepage.
- Advantageous embodiments of the invention are obtained in accordance with the dependent claims.

system 1 comprises a draught-excluder device 2 mounted along the bottom edge E1 of the leaf L and having a box-shaped body 3 which defines a longitudinal axis X. - The box-
shaped body 3 can be mounted by means of gluing or screwing means within a longitudinal groove H formed along the bottom edge E1 of the leaf L. - Furthermore, the box-
shaped body 3 has a substantially U-shape with a pair ofvertical side walls 4 and ahorizontal top wall 5, which are adapted to be secured to the inner walls of the groove H of the leaf L. - As is well known, the length of the box-
shaped body 3 is selected to engage the longitudinal groove H of the leaf L substantially all along its extent. - The
system 1 comprises at least onefirst seal 6 associated with the box-shaped body 3 and adapted to vertically move from an idle lifted position, spaced apart from the threshold F to an operating lowered position contacting the ground and the threshold F. - Advantageously, the
seal 6 may be made of a flexible material selected from the group comprising elastomers or polymeric materials. - The idle position of the
seal 6 corresponds to the open state of the leaf L and the operating position of theseal 6 corresponds to the closed state of the leaf L. - Furthermore, the vertical translation of the
first seal 6 may be caused by a control mechanism, not shown, such as an actuator, which is adapted to contact a respective upright M when the leaf L is closed. - As shown in
FIGS. 6A to 6C , thefirst seal 6 may comprise a pair ofcentral appendages 7, which are adapted to contact the ground F in the lowered position and a substantially verticallateral branch 8 which is partially accommodated in the box-like body 3 and has an outer surface 9 that faces one of theside walls 4 of the box-shaped body 3. - The
first seal 6 may be mounted to appropriate vertically moving actuator means 10, which are accommodated in the box-shaped body 3 to cause vertical movement thereof relative to the threshold F. In addition, the actuator means 10 may be operably connected to the above described control mechanism. - In the idle state, the
seal 6 may have a predetermined width l1 and will be configured to deform transversely to an increased width l2 and submit an increased width l2 with respect to the predetermined width as it contacts the ground F due to the thrust exerted by the actuator means 10 as they slide vertically. - Thus, as the ground F contacts the
first seal 6, a gap of a predetermined size p exists between the outer surface 9 of the latter and the outer surface 11 of theside wall 4 of the box-shaped body 3. - The transversal deformation allows the
first seal 6 to fill the gap p such that its outer surface 9, and particularly the outer surface of one of theappendages 7, will be coplanar with the outer surface 11 of the box-shaped body 3. - In a first embodiment as shown in
FIGS. 6A to 6C , the actuator means 10 may comprise athrust track 12 with a pair of L-shapedlower projections 13', 13", which are joined together by a horizontal connectingportion 14 and a substantially horizontalupper projection 15. - Particularly, the
thrust track 12 may have a substantially U-shapedupper portion 16 which is susceptible to interact with the control mechanism, and a C-shapedlower portion 17. - Advantageously, the
upper portion 16 of thetrack 12 may comprise theupper projection 15 and anadditional projection 18 located below theupper projection 15 and having a horizontal section and a vertical section adapted to delimit arecess 19, whose function will be explained below. Furthermore, the lower C-shapedportion 17 comprises the L-shapedlower projections 13', 13". - The actuator means 10 also comprise a pair of at least partially rigid specially shaped
elements central appendages 7 and thelateral branch 8 of thefirst seal 6 respectively and thetrack 12 is adapted to slide vertically relative to the specially shapedelements first seal 6 contacts the ground F. - As shown in
FIGS. 6A to 6C , the specially shapedelement 20 coupled to thecentral appendages 7 may comprise ahousing 22 delimited by a respectiveinclined wall 23 and a T-shapedformation 24 with a surface 24' fitting into the lower C-shapedportion 17 of thetrack 12. - Advantageously, the
housing 22 will be adapted to receive one of the lower projections 13' of thetrack 12 as the latter slides relative to the specially shapedelements - The sliding movement of the lower projection 13' along the
inclined wall 23 of thehousing 22 causes the above describedfirst seal 6, as shown inFIG. 6C . - In addition, the specially shaped
element 21 coupled thelateral branch 8 of thefirst seal 6 has a folded profile, which is adapted to be housed in therecess 19 of thethrust track 12 when thefirst seal 6 is in the idle position. - In the illustrated embodiment, as the
track 12 slides relative to the specially shapedelements element 21 coupled thelateral branch 8 may define a limit stop for theupper projection 15 of thetrack 12 and the specially shapedelement 20 coupled to theappendages 7 may define a limit stop for the connectingportion 14. - In the operating configuration as shown in
FIG. 6C , theupper projection 15 abuts the specially shapedelement 21 coupled thelateral branch 8, the connectingportion 14 abuts the surface 24' of the other specially shapedelement 20, one of the two lower projections 13' is fully seated in thehousing 22 and pushes on theinclined wall 23 thereof, and thefirst seal 6 is transversely deformed. - In an alternative embodiment of the invention, as shown in
FIGS. 7A and 7B , thefirst seal 6 may comprise a pair offlexible elements 6', 6", each having arespective appendage 7', 7" and a respectivelateral branch 8', 8". - Each of the
appendages 7', 7" and each of thelateral branches 8', 8" has a specially shaped respective connecting portion 7'" and 8'". - In this embodiment, the
thrust track 12 only comprises the U-shapedupper portion 16 with respective interlocking seats 16' for insertion of the connecting portions of theflexible elements 6', 6". - As the
thrust track 12 is lowered, it causes simultaneous transverse deformation of bothflexible elements 6', 6" of thefirst seal 6 in two opposite transverse directions. - In a peculiar aspect of the invention, the
system 1 comprises a pair of substantiallyvertical extension elements 25 which are adapted to be mounted to the side edges E2 of the leaf L and a pair of second substantiallyvertical seals 26 adapted to be mounted to the uprights M of the frame T. - For convenience, the figures only show one
extension element 25 and asecond seal 26 of corresponding pairs at one end of the leaf L. - The
extension elements 25 and thesecond seals 26 have a predetermined height to act as a raised threshold and block water seepage. - The box-shaped
body 3, thefirst seal 6 in the lowered position and theextension elements 25 have respective abutment surfaces 27, 27', 27" for thesecond seals 26 when the leaf L is in the closed position and its side edges E2 face the uprights M. - These parts together will be able to form a kind of barrier, which is rigidly joined to the leaf L and is able to block a water column as high as the
extension elements 25. - For example, if the characteristics of the door/window S so permit, the
system 1 may withstand a wave as high as 7,5cm, considering that thetop end 28 of eachextension element 25 is raised to 8cm from the floor, thereby guaranteeing a seal class "E+" for the door/window S. - Furthermore, it may be appreciated from the figures that the height h of the second seals 26 corresponds at least to the sum of the heights h1, h2, h3 of the
first seal 6 in the lowered position, the box-shapedbody 3 and thecorresponding extension element 25. - Therefore, the
extension elements 25, the box-shapedelement 3 and thefirst seal 6 form together an assembly whose total height h1 + h2 + h3 is greater than the height h1 + h2 of the draught-excluder device 2 and substantially equal to the height h of thesecond seals 26 to form a raised threshold therewith and prevent water seepage. - As shown in the figures, the
extension elements 25 may substantially have a T shape, with a firstvertical portion 29 adapted to be secured in a recess R of the side edge E2 of the leaf L and a secondelongated portion 30 comprising theabutment surface 27". - In an alternative embodiment of the invention, not shown, the section of the
extension elements 25 may have a U shape, or an L shape, with a cavity complementary to a projection of the side edge E2 of the leaf L and at least a straight appendage comprising theabutment surface 27". - Conveniently, the abutment surfaces 27, 27' of the
first seal 6 and the box-shapedbody 3 correspond to the above described outer surfaces 9, 11 and face outwards with respect to the leaf L. - Particularly, the outer surface 9 of the
seal 6 will be adapted to abut the correspondingsecond seal 26, to define therespective abutment surface 27, after its transverse deformation caused by the pressure of the ground F and of the actuator means 10. - Therefore, after the transverse deformation, the
first seal 6 fills the gap p and abuts the respectivesecond seal 26. In the alternative embodiment as shown inFIGS. 7A and 7B , only one of the flexible elements 6' of thefirst seal 6 abuts the respectivesecond seal 26 after transverse deformation. - Furthermore, the
extension elements 25 are placed on top of the box-shapedbody 3 and thefirst seal 6. - Particularly, the
lower end 31 of each of theextension elements 25 may rest, be welded or glued to thetop surface 5 of the box-shapedbody 3 at its longitudinal ends 32 upon application to the side edges E2 of the leaf L. - In this embodiment, the
abutment surface 27" of arespective extension element 25 is oriented outwards with respect to the leaf L and is coplanar with the outer surfaces 9, 11 of thefirst seal 6 and the box-shapedbody 3 along a substantially vertical plane π. - It will be appreciated that the positions of the pair of
extension elements 25 and the pair ofsecond seals 26 is essential to provide a waterproof abutment surface. - Each
extension element 25 may be made of a rigid material, allowing thebottom end 31 to contact the entiretop surface 5 of the box-shapedbody 3 and may be selected from the group comprising low-resilience, high-surface friction coefficient rubbers. - The
system 1 may comprise a pair ofsupports 33 adapted to be mounted to the uprights M of the door/window S and to support each a respectivesecond seal 26. - As shown in
FIGS. 1 to 5 , each of thesupports 33 may be selected from metal sections and may comprise anelongated seat 34 which is adapted to stably retain a respectivesecond seal 26 by friction. - Namely, the
second seal 26 may have a lip portion 26' which projects out of itsrespective support 33 to interact both with the draught-excluder device 2 and with arespective extension element 25, as well as an interlockingportion 26" for stably interacting with theelongate seat 34 of itsrespective support 33. - As shown in the figures, the projecting lip 26' of each
second seal 26 may interact with theabutment surface 27 of thefirst seal 6 upon its transverse deformation in the lowered position and with the above described abutment surfaces 27', 27" of the box-shapedbody 3 and theextension element 25 along the continuous vertical plane π. - In an alternative embodiment, the
second seal 26 may be formed by co-extrusion of silicone having hardness of 60sh at the interlockingportion 26" and silicone foam at the end 26'" of the projecting lip 26', as shown inFIG. 8 . - By this arrangement, the silicone foam end 26'" may ensure a better contact during interaction with the draught-
excluder device 2 and with theextension element 25 even in case of heat distortion, mechanical deformation, or imperfect installation. - The above disclosure clearly shows that the system of the invention fulfills the intended objects and can particularly effectively prevent water seepage, while avoiding the use of raised thresholds.
- The present invention may find application in industry, because it can be produced on an industrial scale in factories for production of sealing elements for doors and windows and may be used for various applications, e.g. for commercial, industrial and private purposes.
