ES2851623A1 - MULTIPOINT SECURITY LOCK FOR SECTIONAL DOORS (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Multi-point security lock for sectional doors, which consists of placing joints in the different bars that transmit linear movement, between the main cylinder and the different anchoring points and between the latter. The joint consists of making a straight cut and an angular cut to the bar that transmits the linear movement. These cuts allow the bar to have traction when it is completely straight, which coincides when the door is fully open or closed, and at the same time, it allows the door to articulate when it is moving from the open position to the closed position, and vice versa.

Description

DESCRIPTION

Multi-point security lock for sectional doors

Technical sector

The main sector in which our invention is framed is that of security locks with two or more anchor points, to mount or install on garage doors, community doors and other doors, regardless of whether they are sectional.

Background of the invention

The current multipoint security locks (figure 1) can only be installed on rigid doors (figures 2 and 3), whether the mechanism is inserted inside the door (figure 2) or if it is placed outside the door. (figure 3). This is due to the fact that the bar (a) that transmits the movement (figure 1), which starts from where the key cylinder (b) (figure 1) is to the adjacent anchor points and the one that joins two anchor points consecutive, it is a rigid steel bar and cannot be bent, regardless of the section (rectangular, square, round, hexagonal, etc ...) it has.

These bars are responsible for ensuring that at each turn of the key in the main lock, there is a linear movement, which is transmitted to the rest of the anchoring points, so that the cylinders or anchor plates come out of these.

Therefore, there is a problem when sectional doors are installed, and that is that, as their construction is based on hinged panels (figures 5 and 6), we cannot install multipoint security locks, what is done is to install so many individual locks As panels the door has, to give it some security, or not to install anything and the door is at the mercy of the mechanical rigidity of the panels.

Explanation of the invention

To solve the aforementioned problem in sectional doors, the present invention consists in placing joints (c) (figure 4 and 4A) to the bars that transmit linear movement. A straight cut and an angular cut are made to the bar (Figures 13 and 14), in which the angular cut has a radius, with center, the center of rotation or hinge of the adjacent panels and length; the distance from the center of the hinge of the panels, to the middle of the thickness of the linear slide bar. The angular cut has a height (h) (figure 13), such that the distance (i) (figure 13), from the axis of symmetry of the bar to the end of the angular cut, is several millimeters, sufficient to create a small hook, with mechanical rigidity so that it does not break at this point and in this way when the door is in a vertical position (figure 13), the bar can transmit the linear back and forth movement, that is, with a turn of the key the bar moves in one direction and when we turn the key in the opposite direction, the bar moves in the opposite direction to the previous one. Therefore, even when cut, it has linear motor skills, which coincide when the door is fully open or closed, and at the same time, it allows the door to articulate when it is moving from the open to closed position, and vice versa.

Sectional doors can:

- have a pedestrian door (figure 5),

- or not have it (figure 6).

Sectional doors have two types of construction:

- with the panels hinged on the outside (d), (figure 7),

- with the panels hinged at the center of their thickness (g), (figure 10).

In both types of construction we can install the multipoint security lock, inside the panels, the same as in figure 2, (figures 8 and 11) or on the outside, the same as in figure 3, (figures 9 and 12).

In all possible combinations of assemblies, (figures 8, 911 and 12) depending on the type of construction and the type of installation of the security lock, the joints are not in the same center of rotation as that of the adjacent panels, distances (e) and (f), (figures 8, 9 and 12), except for the assembly of (figure 11) and therefore, when the door opens and / or closes, different trajectories are described. The articulation of this invention, by its design, is capable of overcoming this difficulty.

The same happens, if the door opens and / or closes and the security lock is unlocked, it is locked having turned the key once, it is locked having turned the key twice and / or it is locked having turned the key other times, if applicable. that the lock allows it. In each of the above cases, the linear scroll bar has a different position and therefore the joint as well. Therefore, the trajectories in the turns are different and the joint must be able to overcome this problem. The articulation of this invention, by its design, is capable of overcoming this difficulty.

In figure 13 we show a section of the sectional door, in the closed position, that is to say, totally vertical. The width of a sectional door that is currently marketed and the dimensions of a bar, of a security lock, which is also marketed today, have been taken. The bar that transmits the linear movement to the different anchor points, remains as a rigid bar, despite being articulated, due to the cut at an angle that we have made. Position [0] shows the position of this joint with the lock open, that is, there is no anchor removed. Position [1] shows the bar moved with respect to the previous point, which is when we have turned the lock key one turn. Position [2] shows the bar moved, a little more than the previous position and that corresponds to the linear movement of two turns of the lock key. The bars are guided and fixed, by guides (j), (figures 13 and 14). These ensure that the bars do not fall to either side and maintain the pre-set alignment.

In figure 14 we show a section of the sectional door, when it is opening or closing. To go from the vertical position to the horizontal position, or vice versa, the panels that make up the door have to take a curve with a certain radius, which is why the panels are hinged to each other. Position [0] shows the inclination of the panels, when we are doing this opening and / or closing maneuver and the security lock is open, that is, the key has not been turned. Position [1] shows the same situation as above, but in which, prior to the maneuver, we have turned the key one turn and the bar has a different position than the previous one. Position [2] shows the same situation as above, but in which, prior to the maneuver, we have turned the key two turns and the position of the bar is different from the previous one.

In all the previous states it is shown that the bar can be articulated, without hindering the rotation of the panels that make up the door, regardless of the turns that we have previously given to the key, in the lock. This can be extrapolated to other situations, taking into account the type of construction of the door and the type of assembly of the lock.

Currently, there are no multi-point security locks with articulated bars for this type of door.

The advantage of our invention is to be able to mount a multipoint security lock on a sectional door, and therefore, to be able to anchor each of the panels that make up the sectional door, giving it a high degree of security.

Preferred embodiment of the invention

The embodiment of the present invention consists in making the rigid bar that the multipoint security locks have, have a series of joints. These hinges must be placed at the same height as the hinges of the adjacent panels, in order to be able to rotate them. The joints consist of practicing a straight cut and an angular cut, in which the angular cut has a radius, with center, the center of rotation or hinge of the adjacent panels and length; the distance from the center of the hinge of the panels, to the middle of the thickness of the linear slide bar. This will allow all the turns to be made, without hindering the panel walls and blocking said movement at any time. The different positions [0], [1] and [2] of figure 14 can be observed.

This type of multipoint security lock, with articulations in its linear sliding bars, is applicable to all sectional doors on the market, regardless of its use.
