BAR FOR LOCKING DOUBLE-LEAF SHUTTERS IN THE CLOSED POSITION

Abstract

The invention relates to a device for locking both shutter leaves in the closed position. It comprises, firstly, two elements 1 and 2 that guide and hold the security bar 3 under the shutter leaves while facilitating its movement beneath them, and secondly, gripping means 4 and 5 located on said bar that facilitate its operation. Element 1 also allows the bar 3 to remain under the left-hand leaf when it is open, thus preventing the user from having to insert or remove said bar each time the shutters are opened or closed. The device is particularly intended for the secure locking of double-leaf shutters of any size.

Description

French patent no. 86 15251, to which this certificate of addition is attached, relates to a U-shaped bar that allows window and door shutters to be locked in the closed position by securing them, using a suitably shaped bolt, to a stop located on the window and door opening. According to an initial version of this bar, it is necessary to place or remove the bar under the left-hand shutter panel each time the shutters are opened or closed, taking care not to drop it outside the room. Furthermore, it appears that the movement of the bar is often hindered by the warping of the shutter panels. To remedy these drawbacks, the present invention proposes a second version of the bar which is characterized in that it contains means allowing its retention under the left leaf when it is open and easy to move under the left and right doors when they are closed These means include - on the one hand, a bar movement guide composed of two elements positioned outside the shutters, one on the left leaf to hold the bar under it and the other on the right leaf to facilitate the movement of the bar under both closed leaves - on the other hand, gripping devices located on the bar itself to facilitate its operation This second version aims to offer users a permanent security lock on the shutters, which eliminates the need to insert and remove the bar under the left-hand sash each time the shutters are opened or closed, as well as its storage. The bar remains in the guide element of the left-hand sash when it is in the open position, preventing it from falling outside the opening. The bar is held in the guide element of the left-hand sash with a maximum movement of 50% of its length, facilitating the movement of the bar under the shutters. The bar slides within the two smooth guide elements, eliminating or preventing warping of the shutter ends.The bar guide that holds the shutters straight - reinforces the end of the shutters. The elements of the bar guide, providing significant reinforcement across the entire width of the leaves, deter burglars. The elements of the bar guide, by positioning themselves at the most vulnerable points of the shutters and by being very resistant, act as a deterrent. The assembly consisting of the locking bar and its guide can obviously be used for the bottom and / or top of shutter leaves. The present invention will now be described in more detail, but without limitation, with reference to the attached drawing, in which Figure I is a perspective view of the guide element of the locking bar intended for the left leaf Figure 2 is a perspective view of the locking bar on the side opposite its latch. Figure 3 is a perspective view of the locking bar on the side of its target. Figure 4 is a perspective view of one of the elements of the locking bar guide mounted on a door leaf. Figure 5 is a cross-sectional view of a shutter leaf on which the locking bar and its guide are mounted. Figure 6 is an exterior front view of door leaves fitted with a locking bar and its guide Figure 7 is a perspective view of a variant of the locking bar guide Figure 8 is a perspective view of a locking bar intended for the top of shutter leaves. Figure I shows, at point I, the guide element receiving the locking bar 3, located under the left leaf, and featuring a lateral longitudinal opening 11, aligned with the template of the trunnion 7 of said bar, guiding the movement of said trunnion; at point 6, a counter-plate preventing or eliminating warping of the leaves; at point I7, a shoulder forming a housing for a template allowing it to receive said bar Figure 2 shows in 3 the locking bar comprising a sliding dowel 7 in the opening II of element I of the guide and limiting the horizontal displacement of said bar to 50% of its length Figure 3 shows the locking bar and its latch at point 3. 9 comprising gripping means in the form of handles 4 and 5 facilitating, on the one hand, the movement of said bar under the leaves and On the other hand, the operation of said bolt, in 8, stopping said bolt limiting its opening to allow the passage of the counter plate 6 in its concave part 10 during the movement of said bar under the leaves, in I8 clip allowing the locking of said bolt to said rod Figure 4 shows at point I an element of the guide for bar 3 and its counterplate 6 mounted on a leaf I2 Figure 5 shows the same elements as Figure 4, with the locking bar positioned in element I of its guide at point 3. Figure 6 shows in I and 2 the two elements constituting the guide of the bar 3 for locking leaves I4 and I2, with, in II, the opening, located only on element I of the guide, receiving the trunnion 7 of said bar, in I3, the cover strip of said leaves. Figure 7 shows in IA a variant of the guide for the blocking bar 3 having a wall 15 improving the movement of said bar. It should be noted that in this embodiment the trunnion 7 is not fixed to the said bar but is assembled to the latter after its insertion into the element of the said guide Figure 8 shows, at 3A, a locking bar equipped with an inverted bolt 9A, allowing the bar to be used at the top of the leaves for bottom and / or top locking, and at I6, rods / handles allowing the bar to be moved from the ground. Elements I and 2 of the guide for the locking bar 3 are fixed to the lower and upper ends of the leaves / shutters, using the existing space generally between the leaves and the shutter opening, or if necessary by reducing the length of the leaves. Element I of the guide being fixed on the left leaf I2 while the trunnion 7 of the bar 3 is already inserted into its opening Il and element 2 of the guide fixed correspondingly on the right leaf I4. With leaves 12 and then I4 closed, the bar 3, along with its latch 9, is moved to the open position using handles 4 and 5. It is then moved from an open position under the left leaf I2 to a closed position under the right leaf I4. The latch is then folded down onto the stop of the leaves and locked onto the bar using clip I8, and finally the latch is closed. This second version of the bar, in addition to its ease of use, has the advantage of reinforcing the ends of the leaves thanks to its guide and of being a safety closure thanks to its locking mechanism which makes it integral to the stop of the leaves. According to an alternative embodiment, the opening II of element I of the guide for bar 3 and the trunnion 7 of said bar are located respectively under said element and under said bar
