Description

CLOSED DEVICE FOR DOOR SLIDING AND PIVOT TECHNICAL FIELD

This invention belongs to the technical field of sliding panel enclosures systems made of glass.

BACKGROUND

Enclosure systems that use glass panels or materials of similar mechanical characteristics are usually formed mainly by a set of panels supported and guided by upper and lower rails that are mounted on the roof and the floor of the passenger compartment on which it is desired to perform the enclosure

In the market there are systems of enclosures with panels that are collected by sliding on the rails, and end up all stored at one end or divided at both ends of said rails. In these systems there is a panel called a door, which can be opened and closed by turning on a virtual fixed axis that joins the upper and lower rails, and therefore, it is not possible to slide along the section. Therefore, in these systems the door is always relegated to one of the ends of the sections, since, not being able to slide along the rails, if it was not located at one of these ends, they would hinder the passage of the panels and not They could be collected conveniently.

In patent application ES2324273 A1 one of these enclosure systems is described with independent panels that are guided by an upper and lower rail. The weight of each of the panels is distributed uniformly and longitudinally along the lower rail, so the upper rail only serves as a guide. Each panel can move individually. The enclosure system in addition to the independent panels has a door, which is the last panel and does not move longitudinally from the collection position. Otherwise, said door has a similar configuration to the rest of the panels, although it includes a closing system.

The utility model ES1149237 U describes in detail how these doors work.

The patent application ES2365575 A1 and WO 2012/175754 A1 show improvements for this type of enclosure systems with independent panels.

These systems are very common in terraces of restaurants and shops in which, due To these limitations, the exit of the clients is at one end or side of the enclosure, which is neither comfortable nor convenient from the point of view of security.

SUMMARY OF THE INVENTION

This problem is solved by a closing device according to claim 1. The dependent claims define preferred embodiments of the invention.

In a first inventive aspect, the invention relates to a closing device comprising:

a lower lane;

a lower pivot, fixed to the lower rail, the lower pivot in turn comprising a selective retaining element and a lower guide element comprising a longitudinal groove of lower passage with a width and a lower turning space with a circular shape pierced by the longitudinal underpass groove, the lower turning space having a diameter;

a fixed door; Y

a sliding door;

where the sliding door in turn comprises a lower fitting, which in turn comprises a lower projection suitable for being retained by the selective retaining element,

wherein the selective retaining element of the lower pivot comprises a surface and a cavity comprised on said surface, said cavity being open so that it is accessible in a sliding direction, thus being suitable to allow the entry of the lower projection, and comprising said cavity suitable retention means for retaining the lower projection when it is located in said cavity; Y

where the cavity has a dimension equal to or less than the width of the longitudinal passage groove.

Advantageously, this closing device allows both panels and doors, fixed and sliding, to exist in the same device, all of them sliding along the lower rail, except the fixed door, but so that only the desired sliding door is retained by the selective retention element, while the rest of the panels can pass over the lower pivot without being retained. The fixing caused by the selective retention element allows to define exactly the axis of rotation of the sliding door.

In a particular embodiment, the lower fitting further comprises a pivot piece whose width is less than the width of the longitudinal groove of the underpass and whose section in plan is circumscribed in a circle whose diameter is the diameter of the lower turning space.

This pivot piece allows the lower fitting of the sliding door to maintain contact with the lower pivot during the turning path of the sliding door, reinforcing the exact positioning of the pivot axis.

In a particular embodiment, the closing device additionally comprises an intermediate separation element, slidable by the lower rail, the intermediate separation element comprising

a support piece intended to slide down the bottom rail; Y

a separation piece suitable for separating two elements that are in the lower rail. This element can work perfectly without doors or panels, since its operation consists in separating any two elements that are being guided in the lower lane. In this particular example, it serves to separate the lower fitting of the sliding door from the lower fitting of a panel. This function is useful when collecting and turning the panels, that is, when the device is to be opened and the panels removed. In this case, the panels slide to one end of the lower rail, and once in that position they can exit the lower and upper rails by turning, as if they were doors. When the sliding door reaches that end, because the rigid sheet finish may contain protrusions or bevels, it is desirable to leave a certain distance between the sliding door and the panels that are already collected. Therefore, an intermediate separation element is inserted between the sliding door and the adjacent panel on the side on which the lower hardware is located.

In a particular embodiment, the retention means of the cavity of the selective retaining element of the lower pivot are clipping retention means, where the selective retention element comprises flexible ends that admit elastic deformation to receive an element and regain their shape after deformation, to retain said element.

The means of retaining the cavity of the selective retention element have the mission of retaining the lower projection in a reversible manner. The clipping can only be overcome by applying a sufficient force in the sliding direction, which only occurs when the panels are to be collected, since, if the pivot piece is not aligned with the longitudinal groove of rotation, said pivot piece abuts against said groove, and the lower hardware could not move.

In a particular embodiment, the lower guide element of the lower pivot comprises two facing pieces, so that the separation between them constitutes the longitudinal groove of the lower passage and the lower turning space.

In a particular embodiment, each piece of the lower guide element comprises two straight sections joined by a circular section, said pieces being arranged so that the straight sections of both pieces are parallel or oblique and the circular sections of both pieces correspond to sections of Same circumference.

In a particular embodiment, the lower pivot additionally contains a chamfer in each of the parts of the lower guide element, intended to facilitate the insertion, removal and maneuverability of said lower pivot in the lower rail.

In a particular embodiment, the closing device further comprises:

an upper lane;

an upper pivot, fixed to the upper rail, the upper pivot in turn comprising an upper guide member comprising a longitudinal upper passage groove and an upper turning gap with a circular shape opened by the longitudinal upper passage groove;

and where the sliding door additionally comprises

an upper fitting, which in turn comprises an upper plate attached to an upper profile; Y

a rigid sheet attached to the upper profile and the lower profile.

In a particular embodiment, the upper guide element of the upper pivot comprises two facing pieces, so that the gap between them constitutes the longitudinal upper passage groove and the upper turning space.

In a particular embodiment, the upper pivot additionally contains a chamfer in each of the pieces of the guide element, intended to facilitate the insertion, removal and maneuverability of said upper pivot in the upper rail. In a particular embodiment, the rigid sheet is a glass sheet. In a particular embodiment, the upper profile comprises an upper guide projection. In a particular embodiment, the upper rail comprises an upper recess whose width is greater than or equal to the length of the upper guiding projection, such that the distance between the center of the lower turning space and the upper recess is equal to the distance between the center of the lower circular boss and the upper guide boss.

In a particular embodiment, the closing device additionally comprises a stop attached to the upper rail and intended to limit the movement of the upper profile when it exits the upper rail. BRIEF DESCRIPTION OF THE DRAWINGS

In figure 1 a perspective view of a closing device (100) according to the invention can be seen, in which some elements have been displaced from their original place to allow the vision of all the elements. This closing device (100) comprises the following elements:

an upper lane (11);

a lower rail (12);

a lower pivot (1);

a lower hardware (2);

an intermediate separation element (3), slidable on the lower rail (12); a lower guiding element (4);

an upper pivot (5);

a top hardware (6);

a stop (7);

an upper guiding element (8);

a plurality of panels (51);

a fixed door (58);

a sliding door (52) comprising a lower profile (55), an upper profile (56) and a rigid sheet (57);

a lower pocket (53); Y

a top recess (54).

The upper rail (11) and the lower rail (12) are displaced from their original place, so that the lower pivot (1), the lower fitting (2), the intermediate separation element (3), the upper pivot ( 5), the upper fitting (6) and the upper guiding element (8) can be seen. The lower guide element (4) is seen in a detail of the figure.

In this figure three directions have also been represented, for better definition of the elements involved in the present description.

The sliding direction (X) is considered the longitudinal direction along which the upper and lower rails extend. The vertical direction (Z) is considered to be the direction perpendicular to the sliding direction (X) that is contained in the plane of the sliding door. Direction of width (Y) is considered to be the direction perpendicular to the direction of sliding and the vertical direction (Z).

Both the panels (51) and the sliding door (52) are elements intended to slide on the lower rail (12), and comprise a lower fitting, a lower profile, a rigid sheet, preferably of glass, an upper profile and a fitting lower. The difference is that the elements of the sliding door (52) are such that, in combination with elements of the closing device (100), they allow the sliding door (52) to open, leaving the plane defined by the sliding directions ( X) and vertical (Z), while the elements of the panels (51) do not allow it in a position other than that of the fixed door, when the collection of said panels occurs. In this particular example, these elements of the sliding door (52) are: a lower fitting (2), a lower guiding element (4) and an upper fitting (6) and an upper guiding element (8). On the other hand, in this particular example, the elements of the closing device (100) that collaborate with these elements of the sliding door are: a lower pivot (1), an upper pivot (5) and a separation element (3) , together with the lower (53) and upper (54) recesses.

Figure 2 shows a detail of the lower pivot (1) separated from the lower rail (12), although its position within the closing device (100) is fixed to said lower rail (12). This lower pivot (1) comprises the following parts:

a selective retention element (104)

a lower guide element (103) comprising a longitudinal groove of lower passage (105) and a lower turning space (106) with a circular shape pierced by the longitudinal groove of lower passage (105), and

a plurality of through holes (101, 102).

The selective retention element (104) comprises a flat surface (107) and a circular cavity (108) comprised in said flat surface (107). This circular cavity (108) is open, that is, the circular cavity (108) can be accessed both from the flat surface (107), from where the circular cavity (108) is in the shape of a circumference section, and from the sliding direction (X). The fact that this circular cavity (108) is open and accessible from the sliding direction (X) allows the lower circular projection (204) of the lower fitting (2) to access the circular cavity (108) . Said circular cavity (108) also comprises retention means (109) suitable for retaining an element that is located in said circular cavity (108). In this case, these retention means (109) are the flexible ends of the circular cavity (108). These flexible ends (109) allow elastic deformation to receive an element and they recover their shape after deformation, to retain said element. Therefore, in this particular case, the circular cavity (108) has to be larger than a semicircle, since in a semicircle the ends are not able to retain the element that enters the circular cavity. As can be seen in the figure, the circular cavity (108) reproduces a circular sector, that is, part of what would be a complete or closed circular cavity. If it is considered that the complete or closed circular cavity would be 360 °, in this particular example the open circular cavity of the invention runs approximately between 240 ° and 300 °. However, other retention means are possible and compatible with this invention, such as leaving a circular cavity of just 180 ° and providing retention means other than the circular cavity, such as auxiliary pins, a magnet, a ramp to two levels or any other means of retention that can reversibly retain an element within said circular cavity. In any case, although the circular cavity does not complete an entire circumference, the circumference defined by said circular cavity can be known, and this circumference has a diameter that can be calculated.

The lower guide element (103) comprises a longitudinal lower passage groove (105) and a lower turning space (106) having a circular shape pierced by the longitudinal lower passage groove (105). In this particular example, the longitudinal underpass groove (105) and the lower turning space (106) are defined by the space between two pieces (103a, 103b). Each of these pieces (103a, 103b) comprises two straight sections joined by a circular section, and are arranged so that the straight sections of both pieces are parallel and the circular sections of both pieces correspond to sections of the same circumference. Thus, the space between the straight sections of both pieces configures the longitudinal groove of the underpass (105) and the space between the circular sections, which are part of the same circumference, constitute the lower turning space (106), which is shaped circular, but which is crossed by the longitudinal underpass groove (105), since the circular sections do not form a complete circumference, because it is necessary that the longitudinal underpass groove (105) pass through said lower turning space ( 106). In any case, although the circular sections do not form a complete circumference, the circumference defined by the circular sections can be known, and this circumference has a diameter that can be calculated.

In other embodiments, the straight sections are not arranged in parallel, but obliquely. In these embodiments, the space between the oblique straight sections remains the longitudinal groove of the underpass (105).

In this embodiment, the width, measured on the axis of width (Y), between the straight sections of the pieces (103a, 103b) is constant, so that it can be said that the width of the longitudinal underpass groove (105) is a constant amount, which is the distance between said straight sections of the pieces (103a, 103b) . In embodiments in which the straight sections are oblique, the width of the longitudinal underpass groove (105) is considered to be the minimum distance between the straight sections. This distance, therefore, corresponds in both cases to the width, measured on the width axis (Y) of the largest piece that can cross the longitudinal groove of the underpass (105).

The circular cavity (108) of the selective retaining element (104) has a diameter equal to or less than said width of the longitudinal underpass groove (105).

What is achieved with this configuration is a piece that allows the passage of elements whose height is sufficient to impact the lower guide element (103), but is not sufficient to impact the selective retention element (104); and that does not allow the passage of elements whose height is sufficient to impact the selective retention element (104). Furthermore, if said elements have a particular configuration, they are retained by said selective retention element (104), as will be seen later. This lower pivot (1) additionally contains a chamfer (110) in each of the pieces (103a, 103b) of the lower guide element (103), intended to facilitate its insertion, removal and maneuverability once it is introduced into the lower rail ( 12). In this embodiment, the chamfer is in the upper half of one piece (103a) and in the lower half of the other (103b). The through holes (101, 102) serve to connect the lower pivot (1) with the lower rail (12) by means of screws. In other embodiments, the lower pivot (1) is attached to the lower rail (12) by means of gluing or by means of any other fixing means that allows to keep the lower pivot (1) fixed in the lower rail (12) supporting lateral displacement loads.

Figure 3 shows a lower fitting (2) of the sliding door (52). This lower hardware (2) comprises

a lower plate (202) attached to a rigid sheet (57), for example of glass, and to slide along the lower rail (12);

a pivot piece (203);

a lower circular projection (204) suitable for being retained by the selective retaining element (104) of the lower pivot (1), attached to the pivot piece (203); Y a lateral support (206).

The circular projection (204) has a diameter substantially identical to the diameter of the circumference defined by the circular cavity (108) of the selective retaining element (104), or may be even slightly larger, since in this case, when the circular cavity (108) by flexible ends (109), said circular cavity (108) admits a lower circular projection (204) of somewhat larger diameter. This circular projection (204) is intended to be fitted in said selective retaining element (104), in a manner that will be described later.

In turn, the pivot piece (203) has two main dimensions: width and length. The length is the dimension measured in the sliding direction (X), and the width in the width direction (Y), which determines whether the pivot piece (203) can pass through the longitudinal passage groove (105). The width of the pivot piece (203) is smaller than the width of the longitudinal passage groove (105). The length and width of the pivot piece (203) are such that its plan section, which is the section seen from the vertical direction (Z), is circumscribed in a circumference whose diameter is the diameter of the turning space (106 ). This ensures that the pivot piece (203) has the appropriate dimensions that allow it to rotate without play in the turning space (106), once the circular projection (204) is retained by the selective retention element (104) .

The mode of operation is as follows: when the lower fitting (2) of a sliding door (52) slides down the lower rail (12), it reaches the area of the lower rail (12) where the lower pivot is fixed ( one). At this time, the circular projection (204) of the lower fitting (2) reaches the lower pivot (1) and when the circular projection (204) reaches the selective retaining element (104) it is retained by it. Since both the circular projection (204) and the circular cavity (108) have a circular shape, the only movement that allows this coupling is the circular movement.

Once the circular projection (204) is retained by the selective retaining element (104), the pivot piece (203) is located in the turning space (106). As the dimensions of the pivot piece (203) are such that said pivot piece (203) is inscribed in the circumference of the turning space (106), said pivot piece (203) has the ability to guide the fitting lower (2) and, therefore, to the sliding door (52), so that it can rotate with respect to a fixed axis that passes through the center of the circular cavity (108) and which is parallel to the vertical direction (Z) . In this and in other particular examples, the lower plate (202) is a monobloc piece, made in a single piece, and has a cross-section in the form of a cross, with a main surface parallel to the plane defined by the sliding directions (X ) and width (Y) and two ribs, one of them on each side of the main surface, to give greater stability in the path of the plate (202) along the lower rail (12).

The lateral support (206) is an element of the lower fitting (2) adjacent to the pivot piece (203). Its mission is to separate the lower hardware (2) from the sliding door (52) from the lower hardware of the panels (51), providing said lower hardware (2) an additional length to the length of the pivot piece (203) . In order not to interfere in the passage of the pivot piece (203) through the lower pivot (1), the lateral support (206) has a height, measured in the vertical direction (Z) less than the height of the pivot piece ( 203).

On the other hand, the panels (51) also have lower hardware, but these lower hardware of the panels (51) are different from the lower hardware (2) of the sliding door (52), since they have no circular projection. When these lower hardware of the panels (51) pass through the lower pivot (1), since they do not comprise any circular projection, they are not retained by the selective retaining element (104), but are free to continue sliding down the lower rail. (12).

Figure 4 shows another element included in a closing device (100) according to the invention. It is an intermediate separation element (3). In this embodiment, this intermediate separation element (3) is placed in the lower rail (12), being slidable thereon. This intermediate separation element (3) comprises a support piece (301) and a separation part (303).

The support piece (301) is the part of the intermediate separation element (3) that is intended to slide on the lower rail (12), thus allowing the intermediate separation element (3) to slide on the lower rail (12) ). On the other hand, the separation piece (303) is intended to separate any two elements that are in the lower rail (12), so it does not require that said elements be in particular doors or panels, but serves to separate elements any.

In this particular case, it has a shape and size on its sides that would cause it to collide with the adjacent panels when the panels (51) and the door are collected. sliding (52). For this reason, the intermediate separation element (3) is introduced into the lower rail (12), so that the separation piece (303) separates the pivot part (203) from the lower fitting (2) of the sliding door (52) of a piece contained in the lower hardware of a panel (51).

Figure 5 shows a lower guiding element (4) suitable to be placed in the lower profile (55) of the sliding door (52), serving as a guide for the sliding of the sliding door (52) through the lower rail (12). ). This guide element (4) comprises holes (401) for joining the lower guide element (4) to the lower profile (55) of the sliding door (52) and a guide flange (403). The mission of this guide flange (403) is twofold: on the one hand, it has a width, measured in the width direction (Y), which is substantially equal to the width of the bottom rail (12), so it serves as guide in the movement of the lower profile (55) along said rail. On the other hand, its length, measured in the sliding direction (X), is less than the length of the guide flanges of the lower guide elements located in the panels (51). The lower rail (12) comprises a lower recess (53) whose width, measured in the sliding direction (X), is substantially equal to the length of the guide flange (403) of the guide element (4) of the sliding door (52). Thus, the sliding door (52) has the capacity to cross the lower rail (12) through said lower recess (53). As the guide flanges of the lower guiding elements located in the panels (51) have a longer length, said guide flanges cannot pass through the lower rail (12) through said lower recess (53).

Figure 6 shows a detail of the upper pivot (5) separated from the upper rail (1 1), although its position within the closing device (100) is fixed to said upper rail (11). This upper pivot (5) comprises the following parts:

an upper guide element (503) comprising a longitudinal upper passage slot (505) and an upper turning space (506) with a circular shape crossed by the longitudinal upper passage slot (505);

an upper stop element (504); Y

a plurality of through holes (501, 502).

The upper guide element (503) comprises a longitudinal upper passage groove (505) and an upper turning space (506) with a circular shape crossed by the longitudinal upper passage groove (505). In this particular example, the longitudinal upper passage groove (505) and the upper turning space (506) are defined by the space between two pieces (503a, 503b). Each of these pieces (503a, 503b) comprises two straight sections joined by a circular section, and are arranged so that the straight sections of both pieces are Parallel and the circular sections of both pieces correspond to sections of the same circumference. Thus, the space between the straight sections of both pieces configures the longitudinal upper passage groove (505) and the space between the circular sections, which are part of the same circumference, constitute the upper turning space (506), which is shaped circular, but which is crossed by the longitudinal upper passage groove (505), since the circular sections do not form a complete circumference, because it is necessary for the longitudinal upper passage groove (505) to cross said turning space. In any case, although the circular sections do not form a complete circumference, the circumference defined by the circular sections can be known, and this circumference has a diameter that can be calculated.

In other embodiments, the straight sections are not arranged in parallel, but obliquely. In these embodiments, the space between the oblique straight sections remains the longitudinal overpass slot (505).

In this embodiment, the width, measured on the axis of width (Y), between the straight sections of the pieces (503a, 503b) is constant, so that it can be said that the width of the longitudinal overpass slot (505 ) is a constant quantity, equal to the distance between the straight sections of the pieces (503a, 503b). In embodiments in which the straight sections are oblique, the width of the longitudinal passage groove (505) is considered to be the minimum distance between the straight sections. This distance, therefore, corresponds in both cases to the width, measured on the axis of width (Y) of the largest piece that can cross the longitudinal groove of overpass (505). This upper pivot (5) additionally contains a chamfer (510) in each of the pieces (503a, 503b) of the guide element (503), intended to facilitate its insertion, removal and maneuverability once introduced in the upper rail (11 ). In this embodiment, the chamfer is in the upper half of one piece (503a) and in the lower half of the other (503b). The upper stop element (504) is located between the parts (503a, 503b) of the upper guide element (503), and has the function of preventing the passage of the elements whose dimensions are sufficient to impact against it, and of allow the passage of elements whose dimensions are not sufficient to impact it. The through holes (501, 502) serve to connect the upper pivot (5) with the upper rail (11) by means of screws. In other embodiments, the upper pivot (5) is attached to the upper rail (1 1) by means of gluing or by any other fixing means that allow to keep the upper pivot (5) fixed in the upper rail (1 1) supporting lateral displacement loads.

Figure 7 shows an upper fitting (6) of a sliding door (52). This upper hardware (6) comprises

an upper plate (602) attached to the rigid sheet (57), suitable for being guided by the upper rail (11);

a pivot piece (603);

a guide piece (605); Y

a hole (601) for joining the upper fitting to the upper profile (56) and a hole (604) for joining the pivot piece (603) to the rest of the upper fitting (6)

The pivot piece (603) has two main dimensions: width and length. The length is the dimension measured in the sliding direction (X), and the width in the width direction (Y), which determines whether the pivot piece (603) can pass through the longitudinal passage groove (505) of the upper pivot (5). The width of the pivot piece (603) is smaller than the width of the longitudinal passage groove (505). The length and width of the pivot piece (603) are such that its section in plan, which is the section seen from the vertical direction (Z), is circumscribed in a circumference whose diameter is the diameter of the turning space (506 ) of the upper pivot (5). This ensures that the pivot piece (603) has the appropriate dimensions that allow it to rotate without play in the turning space (506) once it has butted against the upper stop element (504). The mode of operation is as follows: when the lower fitting (6) of the sliding door (52), guided by the upper rail (11), reaches the area of the upper rail (11) where the upper pivot is fixed (5). At this time, the pivoting part (603) of the upper fitting (6) reaches the upper pivot (5) and stops at the upper stop element (504).

Once the pivot piece (603) is stopped by the upper stop member (504), said pivot piece (603) is located in the turning space (506). As the dimensions of the pivot piece (603) are such that said pivot piece (603) is inscribed in the circumference of the turning space (506), said pivot piece (603) has the ability to guide the fitting upper (6) and, therefore, to the sliding door (52), so that it can rotate with respect to a fixed axis that passes through the center of the turning space (506) and which is parallel to the vertical direction (Z) . On the other hand, the panels (51) also have upper fittings, but these upper fittings of the panels (51) are different from the upper fittings (6) of the sliding door (52), since its pivoting part has a dimension lower in the vertical dimension (Z) than the pivot part (603) of the lower fitting (6) of the sliding door (52). When these lower hardware of the panels (51) pass through the upper pivot (5), they do not stop at the upper stop element (504), but are free to continue advancing along the upper rail (1 1). Figure 8 shows a stop a stop (7), intended to be attached to the upper rail (11). The function of this stop (7) is to limit the movement of the upper profile (56) when it exits the upper rail (11) when the sliding door (52) opens. This stop comprises two holes (702) for connection with the upper rail (11) and a stopper element (701), intended to limit the movement of the upper profile (56) when it leaves the upper rail (1 1) when it occurs the opening of the sliding door (52).

Additionally, both the sliding door (52) and the panels (51) comprise upper guide elements (8) located in the upper profile (56). The upper rail (11) comprises an upper recess (54) whose width measured in the direction of travel (X) is greater than or equal to the length of the upper guide element (8) measured in said direction of travel (X). Thus, when the sliding door (52) is opened, the upper guide element (8) can pass through the upper rail (11) by means of said upper recess (54). Reference List
