FR2806120A3 - Door reinforcing strut comprises elongated triangular frame which is rotated through 90 degrees and has bolt to engage with floor plate - Google Patents

Abstract

The strut consists of an elongated triangular iron frame (1) mounted on pivots (3) on the inside of the door (2) so it can be rotated through 90 degrees. The bottom corner of the strut has a tube containing a spring-loaded bolt (9) which engages with a hole in a floor plate (12) when the strut is deployed. The strut can be deployed from outside the door by a bevel gear mechanism (4, 5) and a spindle passing through the door, operated by a key.

Description

The present invention relates to a security device for door and against any break-ins.

The door security system is traditionally made using multi-point locks that act as a point of force on the fixed amounts of a door and floor: the locks also have a certain resistance, despite this the break-ins exist especially during a external thrust made with force.

The device according to the invention overcomes these strong outbreaks, which paralyzes the disadvantage. It has indeed according to a first characteristic, a ferrous skeleton triangular form called strut, the latter is extensible in height and partly base The skeleton is placed parallel to the door from the inside: its action position is set up by a rotation due to a key positioned outside when the skeleton has rotated 90 degrees it is placed in the safety position; Then comes to lodge on the ground on a plate 'a projection receives a rod placed vertically in relaxation by a spring and sliding ended by a rounded to marry the uneven ground and get a smooth passage.

According to particular embodiments: the triangular skeleton can be partially filled or actuated from an already existing lock.

The accompanying drawings illustrate the invention.

Figure 1 shows the device of the invention in the safety position. Figure 2 shows the device of the invention in the non-actuated position.

Figure 3 shows the device of the invention which allows rotation at 90 degrees. FIG. 4 represents the device of the invention which consolidates its stopper.

Figure 5 shows in section the device of the invention which allows the base piece to marry the inequalities of the ground with the help of the spring stop in the projection plate.

With reference to these drawings, the device comprises a skeleton (1) of triangular shape fixed parallel to the door (2) by hinges (3). A set of pinions (4) (5) of return. One of the pinions (5) of return is in a horizontal position and secured to the parallel portion 'the door (2) of the skeleton (1). The other idler gear which drives the pinion (5) is vertical and in rotation action by a horizontal axis (6) housed in the door thickness (2) which will allow the device (1) to deploy on a 90-degree angle The device deployed at 90 degrees is therefore in the safety position will have at the end of its base a hollow rod (7) which houses a spring (8) which caps another rounded rod (9) rounded shape (10) which is positioned in the projection (11) the plate (12) fixed to the ground.

According to variant not illustrated, the skeleton (1) may be partially full and of variable dimensions.

The device according to the invention is particularly intended to prevent tampering opening doors or any access, openings, passages that require a full closure or openwork <B>: </ B> and delimits, protects, prohibits a place.

Claims (4)

1) Safety device having a skeleton (1) of triangular and articulated shape, called Force Leg. 2) Device according to claim 1 characterized in that the pinions (5) (4) of references operate the skeleton (1) at 90 degrees by rotation. 3) Device according to claim 1 characterized in that the skeleton (1) comprises a hollow stem base which houses a spring (8) and fits another rod (9) with a round end all serves as a stop. 4) Device according to claim 3 in that the rod (9) is housed in a projection (11) comprises the plate (12) placed on the ground.
