The present invention describes a locking system for sliding-pivoting doors/panels systems which are independent between them. These systems normally are made of aluminium and glass, and are used for delimitation, enclosurements, or isolation of spaces, either in houses (balconies, patios, porches . . . ) or in businesses (restaurants, offices . . . ).
This invention can be included into the technical sector of building systems or materials, in particular, in the sliding-pivoting doors/panels systems which are independent between them.
Documents PCT/ES2010/000187 and PCT/ES/2011/00210 describe sliding-pivoting doors/panels systems which are independent between them. All these systems have in common that the pivoting movement is made at one of the sides, wherein a panel works as a normal door. Documents WO2004/011752 A1 and ES2241534T3 show different locking systems. In these systems, when the first panel, normally called door, is blocked, the whole system is blocked too as the rest of the panels fold or pivot at the position of this first panel/door. Else more, the pivoting movement can be done by means of two leverage points, one of them is the top pivot axis and the other one is normally placed at the opposite upper corner of the former point. This second leverage action is done using a part that is perpendicular to the sliding system plane. Documents DE 10333612 (A1) and ES 2262013T3 show systems that include a perpendicular arm as a leverage point.
Each system has its own locking system with a moving opening part and another one that is fixed. The opening part is always placed in the first panel or door. The fix part is always positioned on the top sliding track. There are solutions, as described in document ES 2241534T3, wherein the opening part is based on a cable that enables a top and bottom locker placed on the opposite side to the axis one in the first panel or door. The fix leverage part is perpendicular to the sliding system plane and can be done with different shapes and sizes.
The invention describes a locking system wherein the door locking points are close to the pivoting axis, as a difference with the present ones, whose points are in the opposite side of the pivoting axis. Elsemore, this locking system shifts the upper leverage point, placed in the top corner of each panel, opposite to the top axis, to a point contiguous to the top axis and, moreover, eliminates the top part perpendicular to the sliding system plane that works as a leverage part to enable the pivoting movement for every panel.
The locking system described in this document offers an improvement in the present state of the art as it makes all the panels of the system look the same way and eliminates all vertical opening elements in the first panel or door. Moreover, this locking system is much more resistant to impacts, savotages and extreme weather conditions as strong winds. Finally, improves dramatically the hermeticity of these locking systems as a all the panels are pushed together in a longitudinal way, so there is no gap in between the panels, stopping the water and air coming in.
The leverage system for the pivoting operation of all the panels has some improvements over the state of the art. First of all, eliminates the leverage part that is perpendicular to the sliding system plane and it is made of plastic normally, as shown in document PTC/ES2010/000187. Second, allows the installation of solar protection systems in the indoor side of the system, placed on top of the first panel or door, where the folding or pivoting movement takes place. It is that way, because these solar protection systems are roll operated or just foldable, being fixed onto the ceiling, being its opening movement parallel to the system plane. The existence of the fixed perpendicular part mentioned before, blocks the operation of this rolling or foldable systems as they hit it.
The locking system is made of a two set mechanisms described as follows.
The first locking system set works in such a way that a “U” shape aluminium profile is inserted into another “U” shape aluminium profile and has an internal mechanism to operate it. It is possible to modify the distance between the two bases of the “U” shape profiles by means of an external handle. One of the “U” shape profiles is fixed to the wall and the other can move from the other. By means of this movement it is possible to lock or unlock the systems based on independent, sliding and pivoting panels.
The two “U” shape profiles, both fitted and one of them can move inside the other, are placed at the same panel/door side where the pivoting parts are positioned in each panel/door, and they go from the top to the bottom track. All the panels have a unique pivoting axis that is provided and defined by parts, with a half-moon shape, placed inside the top track and are all aligned. Therefore, each pivoting panel has a pivot part on its top corner with a rounded head that enables the pivoting movement as this head matches its predefined half-moon shape part mentioned before. Each panel has a defined position to do its pivoting movement. There are many possible implementations or solutions to achieve this pivoting movement, but the basic mechanics of it are described before. Documents PCT/ES2010/000187 and PCT/ES/2011/000210 show two technical solutions for the pivoting movement.
Locking and unlocking the system is achieved by a slight longitudinal movement of the first panel or door, in such a way that the top pivoting part of the panel doesn't match its corresponding half-moon, it is slightly shifted, resulting in a blocked position for the top rounded head part as it can't rotate or pivot inside its half-moon shape part. As one “U” shape aluminium profile moves inside the other a distance that equals the shift mentioned before, the pivoting movement of the panel is allowed as the top pivot part matches perfectly its corresponding half-moon shape part. Therefore, the system has an open position and a closed position. The closed position implies that the base of the “U” shape profiles are at their furthest possible distance, in the reverse, the open position implies they are at this closest possible distance. The system in the closed position makes the first panel or door to be tightly close to the next panel, and so on with the rest of the panels. The system in the open position generates a gap in between the base of the “U” shape profile furthest from the wall and the glass edge of the first panel or door. This gap is right the shift distance mentioned before that allows the perfect matching of the top pivot part, with a rounded head and fixed inside the top aluminium profile, and the half-moon shape part, fixed inside the top track. By sliding slightly the first panel or door in such a way that this gap disappears, the pivoting movement is allowed, and therefore the panel can be folded. Next panels will work exactly the same way as the distance in between axes for every panel is kept constant and equals the gap distance mentioned before. The first panel/door sliding movement is done with the help of a small knob placed on the surface of its glass.
The approaching and moving away movement in between the two “U” shape profiles is achieved by means of a handle that turns on its axis, as it turns, a vertical movement of two internal long flat plates happens, this vertical movement is parallel to the base of the two “U” shape profiles. Those internal long flat plates are placed along the inside of the interior rectangular hole defined by the two “U” shape profiles, and are both connected in one of their ends to a small plate each, which are part of the internal face of the handle. This vertical movement is converted into a horizontal movement using a 90 degree part, elbow shape, placed on top and bottom of the internal rectangular hole of the locking system. This elbow shape parts are one piece components, with an internal plate with two ends, both out of the elbow shape structure. As the internal plate moves inside, one end goes up-down and the other goes right-left at the same time. The vertical ends of the elbow shape part connect to the internal plates mentioned before by means of a connector, and the horizontal ends connect to two cubic shape parts by means of a connector too. The cubic shape part is fixed to the internal face of the base of the moving “U” profile, so when the cubic part moves it pushes or pulls the moving “U” profile. This way the turning movement of the handle is converted into a horizontal movement of the “U” shape profile and then the first panel or door slides.
The closed position forces the first panel or door to be perfectly matched side by side to the next panel, and so on, this way there is no gap in between the panels and therefore the system is more hermetic against the water and wind. It is frequent that this kind of sliding systems has some disadjustments with the past of the time and the use, so the gap in between the panels can be bigger at some panel joints, this unwanted situation is avoided by this locking system.
The second set of components of this locking system is made of some rectangular shape parts placed inside the top profile of every panel, side by side to each top pivot part. Elsemore, there is an array of slots attached parallel to the top track, in its inner side, in such a way that every rectangular shape part mentioned before passes through a slot, in fact, its corresponding slot, as every panel has a defined position in that array of slots. These slots allow the transversal movement of the panels when the rectangular parts pass through them, but not the longitudinal movement, and therefore, the panel can only move in a transversal way instead of a longitudinal one when doing the pivoting movement. So, there is no need to use a perpendicular part to the sliding system plane as mentioned before to provide a leverage point for every panel when pivoting.
The rectangular shape part that is placed side to side to the top pivot part is designed in such a way that it protrudes from the top profile of the panel. The slot array part does the same from the top track. Both components are placed in such a way that the top protusion of the panel passes through a defined slot when doing the pivoting movement, and by doing so, it avoids any possible longitudinal movement of the panel in relation to the vertical line defined by the top and bottom axis, being possible only the transversal/turning movement in relation to that vertical line. In fact, one part holds the other while the panel is pivoting, as the side of both components are complementary in their shape. By avoiding the longitudinal movement, the panel can not fall during the pivoting operation. This leverage action is achieved at present in these systems using a protruding part perpendicular to the sliding system plane. The result of this improvement is that this perpendicular part can be removed.
The distance in between pivoting axes of every panel is always the same, so every protruding part in the panel and every slot in the top track are predefined and a panel can not be folded passing by the wrong slot.
The first set of components can be removed, using an alternative blocking mechanism made of a rod parallel to the sliding system plane and a blocking pin added to the second set of components. The rod drives a blocking pin in one of the ends of a seesaw which is placed inside the top profile of the first panel or door, when the system is closed, the blocking pin is inside the top track, blocking the opening movement of the panel, as it hits the internal walls of the top track that has a “U” shape. To open the door the rod must be pulled down, so the blocking pin goes down and gets bellow the top track bottom level.
The locking system for sliding and pivoting panels (18 and 19) is composed of two different mechanisms:
Locking and unlocking mechanism (7) for the sliding of the panels (18 and 19). This mechanism (7) is composed of a set of components placed close to the wall:
Guiding mechanism of the panels (18 and 19), placed in the sliding top track (21) and composed of:
A cap (8) to the exit hole of the sliding top track (21)
An array of slots (9) complementary to the inverted “T” shape part (10)
Inverted “T” shape part (10) that protrudes from the top profile (16).
The locking and unlocking mechanism (7) for the sliding of the panels (18 and 19) is shown in
This longitudinal-horizontal movement is transmitted to the moving “U” shape profile (4) by means of two fixing blocks (5). Each block (5),
As shown in
In the open position their bases (22 and 23) are at the closest possible distance.
In the closed position their bases (22 and 23) are at the furthest possible distance.
The distance difference is the size of the gap in between the base (22) of the “U” profile (4) and the vertical line defined by the pivoting axis of the first panel or door (18). This gap equals the distance of the top pivot part of the first panel (18) to its pivoting axis, and as the distance in between axes is constant, is the same distance for the rest of the panels (19) in relation to its corresponding pivoting axis.
Therefore, with the help of the flat plates (6), elbows (2) and fixing blocks (5), the handle (3) can slide longitudinally the door or first panel (18) between the top track (20) and the bottom track (21) and, by doing so, locking and unlocking the system of sliding and pivoting panels (18 and 19).
As shown in
The pivoting movement of the panels (18 and 19) is achieved by means of a half-moon shape parts, not shown in the figures, which are placed in the interior of the top track (21) at the position of the part (9).
The guiding mechanism of the panels (18 and 19) is depicted in
An inverted “T” shape part (10). The base (30) of the T has a bigger section and thickness than the vertical one. The base (30) of the inverted “T” shape (10) in inserted into the top aluminium profile (16) of each panel (18 and 19) and is positioned just side by side to the top pivot element (15) in such a way that the base (30) is completely introduced into the aluminium profile (16). The end part (31) of the vertical part of the T protrudes over the top profile (16) and has a trapezoidal shape with two sides (32) that pass trough its corresponding slot in the array of slots (9). At the top there is a hole for the fixing of the inverted “T” part (10) to the aluminium profile (16).
An array of slots (9) which are complementary to the inverted “T” part (10). As the panel (18 and 19) starts pivoting the upper part (31) of the component (10) passes trough its corresponding slot of the array of slots (9) that is placed in the inner side of the bottom of the top track (21). By doing so, only a transversal movement is allowed to the inverted “T” part (10) that protrudes over the aluminium profile (16). The longitudinal movement of the panels (18 and 19) in relation to the vertical line defined by the pivoting axis is not possible, and they can only move in a circular way around that axis and in a transversal way in relation to the array of slots (9). One of the inner sides of the array of slots (9) becomes a leverage point for every panel (18 and 19) and replaces other state of the art solutions as shown for example in documents PCT/ES2010/000187 and PCT/ES/2011/000210 wherein a protruding part, perpendicular to the sliding system plane, is placed at the same position as the cap (8) in the exit for the panels (18 and 19) of the top track (21). The inner walls (33) of every slot of the array (9), as well as the exterior walls (32) of the end of the vertical part of the inverted “T” (10), are not parallel, this way the same parts (9 and 10) can be used independently of the direction of the opening of the door (18), to the right or to the left.
A cap (8) for covering the exit hole of the top track (21), through this hole pass all the top guiding elements for the panels (18 and 19). Those guiding elements are not shown in the figures. The guiding elements touch the perpendicular leverage part mentioned before to avoid the panel falling when pivoting.
An alternative configuration for the top pivot element (15) is shown in
An alternative way of the locking system, as shown in
