Description

[0001] The present invention relates to a drainage system for horizontally sliding doors or windows.

[0002] In the sector of sliding doors and windows there is a strongly felt problem of draining water, whether it is rain water or from condensation, from the lower transverse element of the fixed frame, on which transverse element the rails or guides for the support and sliding of the door or window leaves are obtained. In fact, the aim is to prevent water penetrating into the environment closed by the door or window and stagnating in the door or window itself, as well as limiting the inlet of air from the outside towards the inside of the environment closed by the door or window.

[0003] There are numerous drainage systems for sliding doors or windows currently known.

[0004] Known drainage systems are schematically shown in figures 12 to 15 appended to the present description.

[0005] Generally, the lower transverse element comprises one or more rails or guides for the support and sliding of respective door or window leaves. Alongside such rails or guides a longitudinal channel runs, which is open at the top.

[0006] With reference to the appended figures showing the prior art, they show a transverse element T provided with a pair of rails R between which a sealing dowel U is interposed, which separates the "outer side" which is turned towards the environment AE external to the compartment closed by the door or window, from the "inner side", which is turned towards the environment AI internal to such compartment.

[0007] Known drainage systems (Figures 12, 12A and 12B and 13, 13A and 13B) consist of the provision in the transverse element T of a plurality of openings that are in fluid communication with one another and that form a drainage path P that discharges into the external environment. The opening that opens directly into the external environment is generally covered with a cap C that is open at the bottom for discharging the drained water. The cap C is inserted with a snap fitting into the respective opening obtained in the transverse element and is generally provided with a movable doors adapted to prevent the entry of air from the outside to the inside.

[0008] As it can be immediately understood by a person skilled in the art, Figures 12, 12A and 12B show an "outer side" drainage system and Figures 13, 13A and 13B show an "inner side" drainage system, such systems being able to be combined with one another.

[0009] Some known drainage systems, schematically illustrated in Figures 14, 14A and 14B, imply the use of drainage bushings B with valves that allow the outflow of water from the inside towards the outside until the thrust exercised by the water is such as to overcome the external pressure. When the external pressure exceeds a determined threshold value, the valve closes preventing the inlet of water into the door or window and infiltrations of air.

[0010] These known systems have some drawbacks.

[0011] In fact, their drainage capacity is limited to the dimensions of the slots and of any bushings and valves.

[0012] Furthermore, the water that cannot flow outside stagnates in the tubular ducts internal to the transverse element.

[0013] These drawbacks have in part been overcome by another known drainage system (Figures 15, 15A, 15B) which entails the use of a drainage tray V which is inserted slidingly in relevant slots obtained in the transverse element T and into which at least one drainage opening opens, which drainage opening is obtained on the bottom of the channel that runs parallel to the rails and into which an outflow bushing B is inserted. The drainage tray V is provided with a front wall crossed by at least one discharge opening protected by a covering cap. Such a known drainage system is generally used for "outer side" drainage and, with respect to the known drainage systems as described above, it has greater drainage capacity and allows stagnation in the tubular ducts internal to the transverse element to be prevented. However, its use is limited by the fact that as the conformation and dimensions of the lower transverse element vary, a drainage tray with a different conformation and dimensions must be used, with consequent high design, production and storage costs. Furthermore, the adoption of a drainage tray of the known type for the drainage both of the "inner side" and of the "outer side" has the disadvantage of infiltrations of air and dirt from the external environment towards the environment internal to the compartment closed by the door or window.

[0014] The aim of the present invention is that of providing a drainage system for horizontally sliding doors or windows that has a high drainage capacity and prevents the diffusion of the drained water into the tubular duct internal to the transverse element and consequent stagnation thereof.

[0015] Another aim of the present invention is that of providing a drainage system for horizontally sliding doors or windows that can be easily adopted on transverse elements with a different configuration and dimensions for draining both of the "inner side" and of the "outer side", eliminating infiltrations of air into the environment closed by the door or window.

[0016] Still another aim of the present invention is that of providing a drainage system for horizontally sliding doors or windows that can be easily mounted and dismounted with a limited number of operations.

[0017] It is another aim of the present invention to provide a drainage system for horizontally sliding doors or windows, which is particularly simple and functional, with reduced costs.

[0018] These aims according to the present invention are achieved by providing a drainage system for horizontally sliding doors or windows as set out in claim 1.

[0019] These aims according to the present invention are also achieved with a drainage tray for a drainage system for horizontally sliding doors or windows as set out in claim 13.

[0020] Further features are comprised in the dependent claims.

[0022] With reference to Figures 1 to 11E, a drainage system 10 for horizontally sliding doors or windows according to the present invention is shown.

[0023] Sliding doors or windows are known to a person skilled in the art and are described and illustrated herein by way of example only with reference to the components useful for the understanding of the present invention, without thereby constituting any limitation.

[0024] Such doors or windows comprise a fixed frame on which one or more leaves of a window or a door are mounted, at least one of which is supported in a horizontally sliding way.

[0025] The fixed frame comprises a lower transverse element 100 which is generally constituted by one or more extruded profiles coupled to one another and/or provided with sealing and/or thermally insulating gaskets and that are not described in detail being they known to a person skilled in the art.

[0026] The transverse element 100 comprises at least one rail 101 or guide adapted to support at least one leaf 200 of a door or window.

[0027] Generally, the transverse element 100 comprises at least two rails 101 or guides parallel to one another, on each of which a respective leaf 200 is mounted, wherein one of the two leaves 200 is mounted slidably onto the respective rail 101 or guide.

[0028] The transverse element 100 can also be provided with more rails or guides each supporting a respective fixed or sliding leaf according to configurations known to a person skilled in the art.

[0029] At least one channel 102 runs parallel to the rails 101. The channel 102 is generally open at the top and is delimited along at least one side by a rail 101.

[0030] The transverse element 100 then comprises at least one tubular duct 103 that extends along the longitudinal extension of the transverse element itself and internally thereto. The tubular duct 103 has an outer lateral wall 104 and an upper wall 105 that defines the bottom of the channel 102.

[0031] Outer lateral wall 104 means the wall that longitudinally delimits the tubular duct 103 and which, in the mounting configuration of the door or window, faces the environment external to the compartment closed by the door or window itself.

[0032] In the appended figures, AE schematically indicates the external environment and AI the internal environment to the compartment closed by the door or window.

[0033] It is specified that the tubular duct 103 may be of the type with one or more internal chambers separated from one another by intermediate walls 130 according to the configuration of the transverse element 100.

[0034] The upper wall 105 is crossed by at least one drainage opening 106 and the outer lateral wall 104 is crossed by at least one slot 107.

[0035] The drainage opening 106 and the slot 107 are obtained at the same longitudinal portion of the transverse element 100.

[0036] When the tubular duct 103 comprises various internal chambers separated from one another by intermediate walls 130, each intermediate wall 130 interposed between the outer lateral wall 104 and the drainage opening 106 is crossed by at least one respective slot that matches and is aligned with the slot 107.

[0037] The drainage system 10 comprises at least one drainage tray 11 (indicated for simplicity purposes below as tray 11) which can be inserted transversally into the tubular duct 103 through the slot 107 and that is adapted to extend below the drainage opening 106.

[0038] The tray 11 has a front wall 12 and a rear wall 13 opposite one another along the longitudinal extension of the tray 11.

[0039] The front wall 12 is adapted to cover the slot 107 and is provided with at least one discharge opening 14 that leads into the external environment AE for discharging the drained water therein.

[0040] The rear wall 13 is adapted to be housed in the tubular duct 103, generally beyond the edge of the drainage opening 106 further from the outer lateral wall 104.

[0041] According to the present invention, the tray 11 comprises:

• a first tray-shaped body 15 that is provided with the front wall 12 and that is open at the top and at the rear, and
• a second tray-shaped body 16 that is provided with the rear wall 13 and that is open at the top and at the front.

[0042] The first tray-shaped body 15 and the second tray-shaped body 16 can be coupled to one another in one of a plurality of different relative positions along a direction D perpendicular to the front wall 12 and to the rear wall 13 for regulating the length of the tray 11 as a function of the distance H between the slot 107 and the drainage opening 106, a distance that is measured on a plane perpendicular to the longitudinal extension of the tubular duct 103.

[0043] The distance H, in particular, is defined between the outer lateral wall 104 and the edge of the drainage opening 106 which, on a plane transverse to the longitudinal extension of the tubular duct 103, is more distant therefrom. The length of the tray 11 is thus regulated as a function of the maximum distance between the slot 107 and the drainage opening 106, so that the first is greater than or equal to the second one so that the tray 11 extends in length below the entire drainage opening 106 to collect the water that flows out therefrom.

[0044] As it can be immediately understood by a person skilled in the art, the useful width of the tray 11 - and, therefore, of the first tray-shaped body 15 and of the second tray-shaped body 16 that constitute it - is greater than or equal to the maximum size that the drainage opening 106 has parallel to the longitudinal extension of the tubular duct 103, so that the tray 11 extends, not only in length, but also in width below the entire drainage opening 106.

[0045] In other words, in plan view, considering the drainage system 10 in the mounting configuration, the drainage opening 16 is contained in the useful dimensions of the tray 11.

[0046] The first tray-shaped body 15 comprises a bottom 15a connected with the front wall 12 extending along a plane substantially perpendicular to the same and a pair of lateral sides boards 15b joining the bottom 15a with the front wall 12. The bottom 15a and the lateral sides boards 15b extend from the face of the front wall 12 which, in the mounting configuration, faces the rear wall 13.

[0047] The second tray-shaped body 16 comprises a bottom 16a connected with the rear wall 13 extending on a plane substantially perpendicular thereto and a pair of lateral sides boards 16b that join the bottom 16a to the rear wall 13. The bottom 16a and the lateral sides boards 16b extend from the face of the rear wall 13 which, in the mounting configuration, faces the front wall 12.

[0048] The volume delimited by the first tray-shaped body 15 is adapted to contain at least one portion of the second tray-shaped body 16, advantageously the entire second tray-shaped body 16 possibly with the exclusion of the rear wall 13.

[0049] The coupling of the first tray-shaped body 15 and of the second tray-shaped body 16 in one of a plurality of different relative positions along the direction D can be obtained by means of a plurality of coupling seats 17, which are obtained in one of the first tray-shaped body 15 and the second tray-shaped body 16 and are arranged in succession one after the other along the direction D defining said plurality of positions, the other one of the first tray-shaped body 15 and of the second tray-shaped body 16 comprising at least a coupling element 18 for the coupling with at least one of the coupling seats 17.

[0050] The coupling of the first tray-shaped body 15 and of the second tray-shaped body 16 can take place along a coupling direction F that is substantially perpendicular to a plane parallel to the bottom of the tray 11. Furthermore, advantageously, when the first tray-shaped body 15 and the second tray-shaped body 16 are coupled to one another, the relative sliding with respect to one another along parallel directions to such plane and, in particular, along transverse directions to the direction D, is prevented, for example, by a form-fitting.

[0051] In a possible embodiment, one of the first tray-shaped body 15 and of the second tray-shaped body 16 comprises a plurality of teeth 19 that are arranged in succession one after the other along the direction D, wherein the spaces between the teeth 19 define said plurality of coupling seats 17 or positions. The other one of the first tray-shaped body 15 and of the second tray-shaped body 16 comprises at least one respective tooth substantially complementary to one of said spaces and defining said at least one coupling element 18.

[0052] With reference to the embodiment shown in the appended figures, the first tray-shaped body 15 comprises two rows of teeth 19 that extend perpendicular to the bottom 15a at the lateral sides 15b so as to leave a central channel free.

[0053] The teeth 19 are parallel to the front wall 12 and are in succession one after the other equally spaced along the direction D. The spaces between the teeth 19 define the coupling seats 17.

[0054] The second tray-shaped body 16 comprises a pair of teeth defining respective coupling elements 18 complementary to the coupling seats 17.

[0055] The coupling elements 18 extend from the lower face of the bottom 16a (i.e. the face opposite the one which in the mounting configuration is turned towards the drainage opening 106) in a direction substantially perpendicular thereto. Each coupling element 18 is inserted in a corresponding coupling seat 17.

[0056] The coupling of the first tray-shaped body 15 and of the second tray-shaped body 16 takes place by inserting the second tray-shaped body 16 into the first tray-shaped body 15 along a direction F substantially perpendicular to the bottom 15a of the latter, so that the coupling elements 18 are engaged in respective coupling seats 17 defining a desired relative position of the first tray-shaped body 15 and of the second tray-shaped body 16 corresponding to the desired length of the tray 11.

[0057] The sliding of the second tray-shaped body 16 with respect to the first tray-shaped body 15 along parallel directions to their bottoms is prevented on one hand by the engagement of the coupling elements 18 with the coupling seats 17 and, on the other hand, by the form-fitting or however the constraint by obstacle formed by the lateral sides 15b, 16b.

[0058] Advantageously, at least one of the first tray-shaped body 15 and of the second tray-shaped body 16 comprises at least one drain chute 20 toward the discharge opening 14.

[0059] The drain chute 20 can be constituted of one or more inclined planes convergent to one another.

[0060] In the embodiment shown in the appended figures, the drain chute 20 is obtained in the second tray-shaped body 16 (i.e. the one that receives water directly from the drainage opening 106) and comprises a plurality of inclined planes that converge towards the centre of the bottom 16a.

[0061] The drainage system 10 further comprises at least one bushing 21 that can be inserted into the drainage opening 106.

[0062] The bushing 21 can be engaged in the drainage opening 106 with a form-fitting, by interference or jointing.

[0063] The bushing 21 has a grille 22 at the end thereof that surfaces on the bottom of the channel 102.

[0064] It is to be noted that the ribs that form the grille 22 are interrupted at the perimeter edge thereof so that the upper end of the bushing 21 is substantially level with the bottom of the channel 102, promoting the outflow of the water into the drainage tray 11 preventing stagnation near the edges of the bushing itself.

[0065] The bushing 21 conveys the water from the channel 102 directly into the drainage tray 11.

[0066] The drainage system 10 further comprises at least one stop adapted to lock the drainage tray 11 into the tubular duct 103.

[0067] Advantageously, such stop is constituted by the same bushing 21 that is adapted to be engaged in the drainage tray 11 locking it by obstacle into a fixed position with respect to the tubular duct 103.

[0068] In that case the bushing 21 has:

• a first tubular portion 21a that is inserted into the drainage tray 11 and, in the case in question, into the second tray-shaped body 16 thereof, forming a constraint by obstacle adapted to prevent the drainage tray 11 from sliding out of the tubular duct 103, and
• a second portion 21b, advantageously flange shaped, which defines the upper end of the bushing itself and at which the possible grille 22 is obtained in a projecting manner; this second portion 21b is the one that is engaged in the drainage opening 106 coupling with a form-fitting, by engagement or interference therewith.

[0069] In a possible embodiment, the first tray-shaped body 15 comprises a cap 23 which projects from the face of the front wall 12 opposite the one facing towards the second tray-shaped body 16 (i.e. the face which in use is turned towards the external environment AE) and that overhangs the discharge opening 14.

[0070] The cap 23 is open at the bottom forming a passage for the water leaving from the discharge opening 14.

[0071] In a further possible embodiment, the first tray-shaped body 15 comprises at least one tab or door 24 which is supported at the front wall 12 in a movable way for opening or closing the discharge opening 14. The door 24 is supported in a movable way - for example by rotation about an axis of rotation A parallel to the bottom of the drainage tray and perpendicular to the direction D - between a first position, in which it is distanced from the discharge opening 14 leaving the passage of water free from the inside to the outside of the tray 11, and a second position, in which it is overlapped with the discharge opening 14, preventing the flow of air from the outside towards the inside of the tray 11.

[0072] The door 24 is normally in its second portion in which, overlapping with the discharge opening 14, it prevents the inlet of environmental air and protects the discharge opening 14 itself from the accumulation of dust and dirt.

[0073] More in detail, the tray 11, or better the first tray-shaped body 15 thereof, comprises a main support 25 that is formed at the front wall 12 and that is adapted to support the door 24 rotatably about an axis of rotation A transverse to the tray 11 between:

• a first position, in which the door 24 is lifted away from the front wall 12 on the opposite side with respect to the rear wall 13 for at least partially uncovering the discharge opening 14, and
• a second position, in which the door 24 is substantially overlapped with the front wall 12 closing the discharge opening 14, the rotation of the door 24 away from the front wall 12 towards the rear wall 13 being prevented.

[0074] The door 24 is normally in its second position.

[0075] In a possible alternative embodiment of the tray 11 shown in Figures 16A and 16B, the tray 11 comprises at least one intermediate support 26 that is formed at an at least one respective position defined between the front wall 12 and the rear wall 13 at a non-null distance therefrom and that is adapted to support at least one respective door 24 rotatably about an axis of rotation B transverse to the tray 11 between:

• a first position, in which the door 24 is lifted toward the front wall 12 away from the rear wall 13, and
• a second position, in which the door 24 is substantially parallel with respect to the front wall 12 forming a septum dividing the tray 11 into respective longitudinal compartments, wherein the respective drainage opening 106 opens into the compartment downstream, with respect to the insertion direction of the tray 11 into the tubular duct 103, of the septum itself.

[0076] The intermediate support 26 is obtained in a respective position spaced by a non-null distance both from the front wall 12 and from the rear wall 13, so that the door 24 supported thereby, when it is in the second position thereof, is not against any of such walls and in particular the front wall 12. In this way, when the door 24 is in its second position, it forms a septum that extends substantially continuously transversally to the tray 11 dividing it into respective longitudinal compartments: a first compartment delimited by the front wall 12, the septum and the side boards 15b, 16b and a second compartment delimited by the septum, the rear wall 13 and the side boards 15b, 16b.

[0077] Advantageously, the coupling between the at least one intermediate support 26 and the door 24 prevents the rotation of the latter away from the front wall 12 towards the rear wall 13.

[0078] With reference to the embodiment shown in the appended figures, the at least one intermediate support 26 is obtained in the second tray-shaped body 16.

[0079] The at least one intermediate support 26 comprises two seats 27 that are obtained in the side boards 16b and aligned with one another so as to define the axis of rotation A and that rotatably support corresponding pins 28 obtained at the opposite ends of the door 24.

[0080] At the seats 27 tabs 29 are obtained which extend parallel to the front wall 12 and prevent by obstacle the rotation of the door 24 towards the rear wall 13 away from the front wall 12.

[0081] The door 24 is constituted by a plate-shaped body that has pins 28 at the opposite ends.

[0082] However, alternative embodiments of the intermediate support 26 and of the door 24 are not excluded.

[0083] The tray 11 can comprise a plurality of intermediate supports 26 obtained at a plurality of respective positions, each of which is defined between the front wall 12 and the rear wall 13 at a non-null distance therefrom, wherein the intermediate supports 26 are in succession, distanced from one another, along the longitudinal extension of the tray 11, and each of which is adapted to support a respective door 24 as described above. As it will appear more clearly below, such an embodiment is particularly useful for drainage systems of transverse elements 100 whose rails delimit a plurality of longitudinal channels.

[0084] The mounting of a drainage system 10 according to the present invention is immediately comprehensible to a person skilled in the art in light of the description provided above and the appended figures.

[0085] Such mounting comprises the following steps:

• providing at least one drainage opening 106 on the upper wall 105 of the tubular duct 103,
• providing at least one slot 107 in the outer lateral wall 104 of the tubular duct 103 (and in any intermediate wall 130 interposed between the outer lateral wall 104 and the drainage opening 106) substantially at the drainage opening 106,
• coupling the first tray-shaped body 15 and the second tray-shaped body 16 in one of the pluralities of possible relative positions that allows the tray 11 to be obtained with a total length such as to extend completely below the drainage opening 106,
• inserting the tray 11 thus obtained into the tubular channel 103 through the slot 107, and
• locking the drainage tray 11 thus inserted by means of at least one stop.

[0086] Such locking can take place by means of the bushing 21 that is subsequently engaged in the drainage opening 106 and which, being inserted for at least one portion of the tray 11, forms a constraint by obstacle that prevents any sliding of the tray 11 with respect to the tubular duct 103.

[0087] The dismounting of the drainage system 10 takes place with inverse operations to those described above.

[0088] Figures 9 and 9A show a drainage system 10 according to the present invention with a transverse element 100 provided with two rails 101 on each of which a respective leaf 200 is mounted. The "outer side" and the "inner side" are separated by a sealing dowel 300. In that case, the drainage system 10 is configured to drain the "outer side" of the door or window, as it is easily understood by a person skilled in the art. Figure 9B schematically shows the processes performed on the transverse element 100 for obtaining the drainage opening 106 and the slot 107.

[0089] Figures 10, 10A and 10B are analogous to Figures 9, 9A and 9B and show the drainage system 10 in the "inner side" drainage configuration of the door or window, as it can be easily understood by a person skilled in the art.

[0090] It is clear that the configurations shown in Figures 9 and 10 can be coupled in a same door or window. In the latter case, adopting a tray 11 as shown in Figures 16a and 16B, it is possible to adjust the position of the door 24 as a function of the drainage arrangement of the tray 11.

[0091] The tray 11 used for the "outer side" drainage will be provided with an "end" door 24 which is supported by the main support 25 at the front wall 12.

[0092] The tray 11 used, in combination with the first, for the "inner side" drainage, will be provided with an "intermediate" door 24 which is supported by the at least one intermediate support 26 in a position upstream, with respect to the insertion direction of the tray 11 into the tubular duct 103, of the respective drainage opening 106 forming a septum that separates the tray 11 into two compartments: a first (front) compartment defined between the front wall 12 and the septum itself and a second (rear) compartment defined between the septum itself and the rear wall 13 and into which the respective drainage opening 106 opens.

[0093] In this combined drainage system (i.e. with trays 11 used for the drainage both of the "outer side" and of the "inner side"), the "intermediate" door 24 of the drainage tray 11 of the "inner side" is arranged downstream, with respect to the insertion direction of the tray 11 into the tubular duct 103, of the drainage opening 106 pertaining to the "outer side" drainage tank 11.

[0094] The presence of one or more intermediate supports 26 for the door 24 allows the position of the latter to be adjusted as a function of the drainage arrangement of the tray 11.

[0095] The drainage system 10 can comprise a plurality of drainage trays 11 and, therefore, a respective plurality of drainage openings 106 and slots 107. It is also possible that a plurality of drainage openings 106 lead into a common drainage tray 11.

[0096] Figures 11A - 11E show a drainage system 10 according to the present invention with transverse elements 100 that differ from one another in terms of conformation and in particular depth (i.e. width). It is to be noted that as the depth increases the length of the drainage tray 11 varies, a variation that is obtained by coupling the first tray-shaped body 15 and the second tray-shaped body 16 in different possible relative positions.

[0097] The drainage system 10 according to the present invention can be combined with other known systems such as for examples valves for inner side drainage or the like.

[0098] Alternative embodiments of the drainage system 10 are not excluded in which, for example:

• the first tray-shaped body 15 and the second tray-shaped body 16 are coupled to one another telescopically along the direction D and the regulation of their relative position (and, therefore, of the total length of the drainage tank 11) takes place by the sliding of one with respect to the other along the direction D,
• the at least one stop could consist of a bayonet mount of the drainage tray 11 into the slot 107 or other equivalent systems;
• the shape of the main support 25, of the intermediate support 26 and of the door 24 could be different.

[0099] The subject matter of the present invention is also only the drainage tray 11 for a drainage system as described above.

[0100] The drainage system according to the present invention has the advantage of allowing the drainage of the water from any position of the transverse element, either on the "outer side" or on the "inner side", with the use of a same drainage tray that can be configured so as to have the necessary length for the specific application.

[0101] Furthermore, it can be adopted in a plurality of transverse elements (profiles) that are different from one another in terms of conformation and dimensions, in particular having different depths (widths). The drainage tray of the system according to the present invention can in fact be adapted to different conformations and dimensions of the transverse elements, in which it is sufficient to perform the drainage openings and slots in the desired positions.

[0102] The drainage system according to the present invention further guarantees a high drainage capacity and prevents stagnation in the tubular ducts internal to the transverse elements.

[0103] The drainage system according to the present invention can be configured for the combined "outer side" and "inner side" drainage with a respective drainage tray, the adjustment of the position of the respective sealing door allowing infiltrations of air to be prevented while guaranteeing the discharge of the drained water.

[0104] The presence of the drain chute further facilitates the outflow of the water collected in the drainage tray.

[0105] The drainage system and drainage tray thus conceived are susceptible to many modifications and variations, all falling within the invention; furthermore, all the details are replaceable by technically equivalent elements. In practice, the materials used, as well as the dimensions, can be of any type according to the technical requirements.
