Description

APPLICATION FIELD

This invention belongs to the technical field of glass pivoting panel enclosure systems.

BACKGROUND

The enclosure systems that use panels made of glass or materials with similar mechanical characteristics mainly tend to be formed by a set of panels that are supported and guided by upper and lower rails that are mounted on the ceiling and the floor of the space in which the enclosure is to be carried out.
There are several panel enclosure systems on the market that are folded by sliding on rails and are all stored at one end or divided at both ends of said rails after a pivoting operation in the area where the door panel is located. In these systems there is a panel that is referred to as door, which can be opened and closed by rotating on a fixed virtual axis that joins the upper and lower rails.
There are sliding and pivoting panel enclosure systems on the market that are folded at one of the ends and operate either by sliding ( PCT/ES2010/000187 PCT/ES/2011/000210 ) or by means of rollers ( DE 10333612 (A1 ) and ES 2262013T3 ). These systems currently require a support point, referred to as arm, to prevent the panels from becoming unhooked when said panels are opened. Said support takes up a space in the transverse direction of the glazing system, this projecting element prevents the installation of elements such as roman or rolling blinds and floor to ceiling curtains, since it is an obstacle to the normal operation thereof.
The present invention eliminates the need for the closure device to incorporate this projecting arm. It also relieves the upper guide element of its function as a support element for the pivoting at the time the panels are folded at one of the ends.
Removing the projecting arms also entails a new closure/locking system of the system in the panel referred to as door. This new closure system is also described in the present invention.

DESCRIPTION OF THE INVENTION

This problem is resolved by means of a closure device according to claim 1. The dependent claims define preferred embodiments of the invention.
The invention relates to a closure device for a pivoting door, the closure device being characterised in that it comprises:

an upper rail;
a lower rail;
a pivoting fixed door, arranged between the upper rail and the lower rail, the pivoting fixed door comprising an upper profile and a lower profile, the pivoting fixed door being adapted to
a cover fixed to the upper rail, the cover comprising a slot;
a closure element fixed to the upper profile of the pivoting fixed door, the closure element comprising a first mobile stop, such that, in an opening position of the first mobile stop, the closure element can pass through the slot of the cover and in a second locking position of the first mobile stop, said first mobile stop represents an obstacle to the closure element passing through the cover.

This closure device enables the opening and closing of the mobile door by means of an innovative closure system that takes up less space and can be more simply and directly actuated. The fact that the cover is fixed to the rail and that the closure element is fixed on the door constitutes a compact and reliable system.
In a particular embodiment, the first mobile stop comprises an inclined surface, such that it can change from the locking position to the opening position by means of pressure carried out on said inclined surface, as a result, for example, of forcing the first mobile stop against a fixed surface that forms a certain angle with respect to said inclined surface. Furthermore, in particular embodiments, the closure element comprises recovery means that enable the first mobile stop to change from the opening position to the locking position. These recovery means can be springs or similar, but can also be elements that are activated by remote control, locks, etc.
This closure device enables the door to be closed without the need to actuate the mobile stop from the outside, but rather by simply pushing the pivoting fixed door towards the closed position thereof.
In a particular embodiment, the first mobile stop can be activated such that it changes from the locking position to the opening position by means of a handle, or by means of a cable or by means of a remote device or any other suitable device.
This closure device facilitates the opening of the door, acting externally on the mobile stop by means of elements that facilitate this action.
In a particular embodiment,
the closure element comprises a second mobile stop, which is integral to the first mobile stop, such that when the first mobile stop is in the opening position, the second mobile stop is also in the opening position, and when the first mobile stop is in the locking position, the second mobile stop is in the locking position; and
that the cover comprises a housing suitable to receive and retain at least a portion of the second mobile stop.
This closure device enables the pivoting fixed door to be located in several positions with respect to the upper and lower rails, due to the fact that the second mobile stop can be inserted into the housing of the cover, the door thus being locked in a slightly open position, which is suitable for ventilation, but with the security that the door will not move until the second mobile stop inserted into the housing is released.
In a particular embodiment, the closure element further comprises a handle adapted to change the position of the first mobile stop and/or the second mobile stop between the opening position and the locking position.
The handle enables easy actuation of the first and second mobile stops.
In a particular embodiment, the closure device further comprises
at least one sliding and pivoting panel, each one comprising an upper profile;
a first support piece fixed to the upper rail; and
a second support piece fixed to the upper profile of the at least one pivoting and sliding panel;
wherein the first support piece comprises a first portion intended to project from the upper rail, this first portion of the first support piece comprising at least two converging edges and two stop edges, that form between 80° and 100° with respect to the converging edges;
wherein the second support piece comprises a first portion intended to project from each one of the upper profiles of the at least one sliding and pivoting panel; this first portion of the second support piece comprising at least two converging edges, at least one of the converging edges of the first portion of the second support piece being intended to be supported on one of the converging edges of the first portion of the first support piece; the first portion of the second support piece further comprising two stop edges, which form between 80° and 100° with respect to the converging edges, these stop edges being parallel to the main direction of the upper profile of the pivoting fixed door.
This closure device advantageously enables the opening and closing of the pivoting fixed door and of the sliding and pivoting panels without having to use an arm that perpendicularly projects from the upper rail. The position of the first support piece, in collaboration with the second support piece placed on the pivoting fixed door, enables the door to be guided during the first pivoting phase, when the likelihood of unhooking is greater. The absence of an arm that projects prevents the inconveniences that this entails when using sun control elements (such as blinds, curtains, etc.), since the arm prevented the normal operation of said sun control elements.
In a particular embodiment, the first support piece comprises a second portion intended to be inserted into the upper rail, such that this second portion is isolated from any first portion of any other first support piece.
This second portion, which is isolated, enables the first support piece to be an individual piece, not a rack, as described in other documents of the state of the art. Having an individual piece provides a number of advantages, since it takes up less space of the insulation mat that tends to be placed between the pivoting fixed door and the upper rail.
In a particular embodiment, the second support piece comprises a second portion, joined to the first portion of the second support piece by means of a slot, this second portion of the second support piece being intended to be inserted inside the upper profile of the at least one sliding and pivoting panel, such that the plan cross section of the first portion of the second support piece is larger than the plan cross section of the second portion of the second support piece.
The fact that the cross section of the first portion is larger than the cross section of the second portion enables a better support of the second coupling piece on the first, ensuring to an even greater extent the opening and closing operation of the pivoting fixed door.
In a particular embodiment, the pivoting fixed door and the at least one sliding and pivoting panel has a thickness, and the closure device comprises a plurality of first support pieces such that the distance between the first portions of the two first adjacent support pieces is four times larger than the thickness of the pivoting fixed door and of the at least one sliding and pivoting panel.
The location of the first support pieces every four doors achieves a very clean installation, and enables great flexibility in the installation since the support pieces are distributed throughout the upper rail, thus enabling a greater compensation when the ground is uneven.
In a particular embodiment, the closure device comprises a number of first support pieces that is the fourth part of the number of sliding and pivoting panels, rounding to the next natural number if the fourth part is not a natural number.
This closure device is compatible with the presence of several sliding panels, which complement the closure of a space.
In a particular embodiment, in which each one of the upper profiles of the at least one sliding and pivoting panel comprises a first edge, and which in each one of the sliding panels, the second support piece is at an increasingly small distance from the first edge of the upper profile of the corresponding panel, such that for each pair of consecutive panels, the difference between the distance of the second support piece to the first edge of the upper profile of a panel and the distance of the second support piece to the first edge of the upper profile of the other panel is constant. In particular embodiments, this constant difference is equal to the value of the thickness of the pivoting fixed door and of the at least one sliding and pivoting panel.
The fact that the second support pieces have this arrangement enables the same first support piece to be used for four sliding and pivoting panels, such that the first support pieces take up even less space in the upper rail. This results in a simpler, inexpensive and insulated installation.
In some particular embodiments, the first support piece further comprises height-adjustable stops intended to be supported on the upper rail, such that the distance between the converging edges and the upper rail can be adjusted by regulating said adjustable stops.
These height-adjustable stops enable the installation of the first support piece even when the clearance between the upper rail and the panel is not that which is initially planned, therefore enabling a greater tolerance in the installation process.
In some particular embodiments, the height-adjustable stops comprise at least one screw adjustable by means of screwing, configured to project an adjustable distance with respect to the second portion.
These are simple embodiments of the adjustable stops, the screw is accessible from the outside and enables the operator to adjust the height even though the support piece is already inside the upper rail.
In a particular embodiment, the first support piece and/or second support piece and/or the cover and/or the closure element comprise fixing means by screwing or by an alternative fixing means.
The fixing means are those suitable in order for the pieces to withstand the operation requirements to which they are subjected.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1A shows a first embodiment of a first support piece 1 that belongs to a closure device according to the invention.
This first support piece 1 comprises a first portion 101 intended to project from an upper rail, this first portion 101 of the first support piece 1 comprising at least two converging edges 102 and two stop edges 103, 103' that form between 80° and 100° with respect to the converging edges 102. Due to the fact that the converging edges 102 are not parallel, one of the stop edges 103' is larger than the other 103.
The first support piece 1 comprises a second portion 104 intended to be inserted into the upper rail from which the first portion 101 projects, such that this second portion 104 is isolated from any first portion of any other first support piece 1.
Figure 1B shows a second embodiment of a first support piece that belongs to a closure device according to the invention.
This second embodiment contains the elements of the first embodiment shown in figure 1A, but additionally contains height-adjustable stops 105, in the form of screws that are adjustable by means of screwing. These adjustable stops are intended to be supported on an upper rail, such that the distance between the first portion 101 and said upper rail on which the first support piece is installed can be adjusted by screwing and unscrewing said screws.
These height-adjustable stops enable the installation of the first support piece even when the clearance between the upper rail and the panel is not that which is initially planned, therefore enabling a greater tolerance in the installation process, by simply placing the first support piece in the rail and adjusting the distance that the adjustable stops 105 project by screwing. The screws are accessible from the outside even with the support piece already placed on the rail. Once this distance has been adjusted, the first support piece can be fixed to the rail by means of the central screw intended for this purpose.
Figure 2 shows a second support piece 2 that belongs to a closure device according to the invention.
This second support piece 2 comprises a first portion 201 intended to project from an upper profile of a sliding and pivoting panel. This first portion 201 of the second support piece 2 comprises at least two converging edges 202, at least one of the converging edges 202 of the first portion 201 of the second support piece 2 being intended to be supported on one of the converging edges 102 of the first portion 101 of a first support piece 1, as shown in figure 1. Moreover, this first portion 201 of the second support piece 2 comprises two stop edges 203, 203' that form between 80° and 100° with respect to the converging edges 202. Due to the fact that the converging edges 202 are not parallel, one of the stop edges 203' is larger than the other 203.
The second support piece 2 comprises a second portion 204, joined to the first portion of the second support piece 2 by means of a slot 205, this second portion 204 of the second support piece 2 being intended to be inserted inside the upper profile of a sliding and pivoting panel, such that the plan cross section of the first portion 201 of the second support piece 2 is larger than the plan cross section of the second portion 204 of the second support piece 2.
Figure 3 shows some elements of a closure device 10 according to the invention:

an upper rail 11;
a lower rail 12;
a pivoting fixed door 3, arranged between the upper rail 11 and the lower rail 12, the pivoting fixed door 3 comprising an upper profile 31 and a lower profile 32;
a plurality of sliding and pivoting panels 33, 34, 35, each one comprising an upper profile 331, 341, 351 and a lower profile 332, 342, 352;
a first support piece 1 fixed to the upper rail 11;
a second support piece 2 fixed to the upper profile 331, 341, 351 of each one of the sliding and pivoting panels 33, 34, 35.

Although in this figure there three sliding and pivoting panels 33, 34, 35, the invention comprises all the embodiments in which this number of panels is different, since the number can vary greatly depending on the surface area to cover. The invention also works in all these cases.
The second support piece 2 is arranged in the upper profile 331, 341, 351 of each one of the sliding and pivoting panels 33, 34, 35, the stop edges 203, 203' of the first portion 201 of the second support piece 2 being parallel to the main direction of said upper profiles 331, 341, 351, the smaller stop edge 203 specifically being oriented towards the inside of the upper rail 11 and the larger stop edge 203' closest to the side towards which the sliding and pivoting panel 33, 34, 35 is adapted to pivot, therefore being oriented towards the outside of the upper rail 11.
The first support piece 1 is arranged in the upper rail 11, such that the first portion 101 projects from the upper rail 11, and is located to receive the support of the second support pieces 2 of the sliding and pivoting panels 33, 34, 35 when they pivot. Likewise, the second support piece 2 is arranged in the upper profile 331, 341, 351 of each sliding and pivoting panel 33, 34, 35 such that the first portion 201 of the second support piece 2 projects from said upper profile 331, 341, 351. In the detail view of this figure 3, part of the upper rail 11 has been eliminated in order to make it clearer, which means that it seems as if the entire first support piece 1 is visible. However, the first portion 101 projects from said upper rail 11, while the second portion 104 is inserted into said upper rail 11.
In this figure it can be seen how at least one of the converging edges 202 of the first portion 201 of the second support piece 2 is intended to be supported on one of the converging edges 102 of the first portion 101 of the first support piece 1. Therefore, the larger stop edge 103' of the first portion 101 of the first support piece 1 is located on the side on the upper rail 11 towards the inside of the first sliding and pivoting panel 33, therefore oriented towards the inside of the upper rail 11, and the smaller stop edge 103 closest to the side towards which the sliding and pivoting panels 33, 34, 35 are adapted to be open, therefore oriented towards the outside of the upper rail 11. In this way, the converging configurations of the first and second support pieces are complementary, so that one converging side 102 of the first support piece 1 is supported on a converging side 202 of the second support piece 2.
The first support piece 1 is fixed to the upper rail 11 by means of fixing means by screwing. In other embodiments, it alternatively comprises other suitable fixing means.
The second support piece 2 is fixed to the upper profile 331 of the sliding and pivoting panel 33 by means of fixing means by screwing. In other embodiments, it alternatively comprises other suitable fixing means.
In figure 4 it can be seen how the pivoting fixed door 3 and each sliding and pivoting panel 33, 34, 35 have a thickness h, the thickness h being measured in the transverse cross section thereof at the height of the upper profile 31, 331, 341, 351.
Returning to figure 3, the closure device 10 comprises a plurality of first support pieces 1 such that the distance between the first portions 101 of two first adjacent support pieces 1 is four times the thickness h of the pivoting fixed door 3 and the sliding and pivoting panels 33, 34, 35.
In this figure it can be seen how each one of the sliding doors comprises an upper profile with a first edge, and each one of the sliding panels comprises a second support piece arranged in the upper profile. In each one of the sliding panels, as the sliding panel is further from the pivoting fixed door, the second support piece is at an increasingly smaller distance from the first edge of the upper profile of said sliding panel. Due to the way the panels fold, this distance decreases by a fixed amount equal to the thickness h of the pivoting fixed door and the sliding and pivoting panels, such that for each pair of consecutive panels, the difference between the distance of the second support piece to the first edge of the upper profile of a panel and the distance of the second support piece to the first edge of the upper profile of the other panel is constant and equal to this thickness h. It can be seen how for the first sliding panel 33, the distance of the second support piece to the first edge of the upper profile is x, and for the following sliding panel 34 it is x-h. Therefore, the difference between these distances for consecutive panels is h. The same occurs if the second 34 and third 35 panels are taken as a reference. The difference is still h.
Figures 5a, 5b and 5c show a closure element 5 that belongs to a closure device 10 according to the invention.
As may be seen in figures 5a and 5c, this closure element 5 comprises a main body 500 and a first mobile stop 501, which may be configured in a locking position, wherein said first mobile stop 501 projects from the main body of the closure element, and an opening position, wherein said first mobile stop 501 is hidden inside the main body 500. The closure element 5 further comprises a handle 502 adapted to change the position of the first mobile stop 501 between the opening position and the locking position.
In other embodiments, shown in figures 5b, the closure element 5 further comprises a second mobile stop 503, integral to the first mobile stop 501, which may be configured in a locking position, wherein said second mobile stop 503 projects from the main body of the closure element, and an opening position, wherein said second mobile stop 503 is hidden inside the main body 500. The second mobile stop 503 projects, in the locking position thereof, at a height somewhat greater than what the first mobile stop 501 projects in the locking position thereof.
The closure element 5 further comprises a handle 502 adapted to change the position of the first mobile stop 501 and the second mobile stop 503 between the opening position and the locking position.
The first mobile stop 501 and the second mobile stop 503 comprise inclined surfaces 504 that enable the locking position to be changed to the opening position by means of pressure carried out on said inclined surface 504, as a result, for example, of forcing the first mobile stop 501 against a fixed surface that forms a certain angle with respect to said inclined surface.
The closure element 5 comprises fixing means by screwing. In other embodiments, it alternatively comprises other suitable fixing means.
Figures 6a, 6b, 6c, 6d, 6e and 6f show different embodiments of a cover 4 that belongs to a closure device 10 according to the invention. In the embodiment of figure 6a, this cover 4 comprises a main body 400 and a slot 401.
The cover 4 comprises fixing means by screwing, which enable the cover 4 to be fixed to the upper rail 11 of the closure device 10. In other embodiments, it alternatively comprises other suitable fixing means.
The slot 401 is designed such that in an opening position of the first mobile stop 501, the closure element 5 can pass through said slot 401, and in a locking position of the first mobile stop 501, said first mobile stop 501 represents an obstacle to the closure element 5 passing through the cover 4, since it would touch the main body 400 of the cover 4. However, when the door is open, and the mobile stops are on the other side of the slot 401, the inclined surface 504 of the first and second mobile stops enables them to change from the locking position to the opening position, by means of a pressure against the main body 400 of the cover 4. These means that a pivoting fixed door can be closed without the need to act on the mobile stops by means of the handle 502 for safety reasons. Due to the fact that the inclined surface 504 is only in one direction, it is not possible for the door to open without actuating the handle 502. In other embodiments, this handle 502 can be substituted for any means that carries out the same function of activating the mobile stops 501, 503 in order to change from the locking position to the opening position. Furthermore, in particular embodiments, the closure element comprises a spring that enables the first mobile stop 501 to change from the opening position to the locking position. In other embodiments, instead of a spring, the closure element includes elements activated by remote control, locks, etc.
Furthermore, in other particular embodiments, illustrated by figures 6b, 6c, 6d and 6e, it can be seen that the cover 4 further comprises a housing 402 suitable for receiving and retaining at least one portion of the second mobile stop 503 of the closure element 5. This enables the closure element 5 to be fixed with respect to the cover 4 in three different positions, which can be seen in figures 7a, 7b, 7c: a first position, when the pivoting fixed door 3 is closed, wherein both the first mobile stop and the second mobile stop are on one side of the slot, retained by the same; a second ventilation position wherein the second mobile stop is at least partially inserted into the housing 402; a third position wherein the door is open and none of the mobile stops 501, 503 are retained by the slot 401 or the housing 402. Therefore, the second mobile stop 503 enables an opening position referred to as ventilation position, wherein the pivoting fixed door is slightly open and locked, thus enabling the passage of air and therefore the ventilation of the room or space enclosed with the system.
Figure 8 shows some elements of a closure device 10 according to the invention:

an upper rail 11;
a lower rail 12;
a pivoting fixed door 3 located between the upper rail 11 and the lower rail 12, the pivoting fixed door 3 comprising an upper profile 31 and a lower profile 32;
a cover 4 joined in a fixed manner to the upper rail 11,
a closure element 5 joined to the upper profile 31 of the pivoting fixed door 3.

This figure shows the relative position between these elements: the closure element 5 is suitable for enabling the complete opening or partial ventilation position or closure of the pivoting fixed door 3 with respect to the upper 11 and lower 12 rail.
