GR1009647B - Protection accessory for security door bolts - Google Patents

Abstract

Novelty: a protection accessory practicable for security door bolts is disclosed. Constitution: the rectangular planar surface 2, the rectangular recess 3 bearing at one side three large and eight narrower flexible blades (1,13) and at the other side a two-face self-adhesive tape 7 assisting its fitting to the casement 5 of the door 4, around the hole-recess 12 of the bolt 6. When the door closes, the blades (1,13) bend, not leaving any void space around the bolt 6. When projecting screw heads exist around the hole - recess 12 of the bolt 6, the surface 2 should be potentially furnished with the projection 11 having two longitudinal holes 8. Advantages: protection of the bolt of knob-free security doors being in locked position; stopping flexible cards from reaching the bolt of the security door and open it.

SECURITY DOOR TONGUE PROTECTION COMPONENT

The invention refers to a security door tongue protection component consisting of a rectangular flat surface (of sufficient thickness) with a rectangular notch and on one side of it carries two or three rectangular wide and eight narrower flexible inclined wings (at an angle) and on the other side of It has double-sided adhesive tape. And the notch around the hole-receptacle of the tongue (of the lock) in the door frame is adjusted.

Security door tongue guards of this type, which fit around the lock tongue socket in the door frame, to protect it from being opened by a card, when it is not locked and has no knob, is not known. The breaking flexible card as it enters the gap (empty space) between the door and the door jamb, at the location of the lock, penetrates due to its thin thickness, elasticity and lack of obstruction and approaches the tongue, pushes it and opens it violating it.

By using this Security Door Tongue Protection Accessory when the door is not locked and when an attempt is made to break it open with the help of a burglary card. As the card attempts to enter the gap between the door and the door jamb, the card is then prevented by the flaps of the fitting from reaching the tongue of the lock, as the tongue is protected peripherally by the flaps of the fitting, and fails to open it.

An advantage of this invention is that it protects the security door tongue when it is not locked, and does not have a doorknob from opening-burglary, by using a tamper card, preventing it from reaching the lock tongue.

The safety door tongue protection component according to the present invention has the characteristic that it consists of a flat rectangular surface (with sufficient thickness) with a rectangular notch (of the same dimensions as the hole-receptacle of the tongue) and on one surface it has two o three wide and eight narrower flexible fins, under a call of about 45 degrees, when not in use. It has a double-sided adhesive tape attached to its second surface, and with the help of which it is attached around the hole-receptacle of the tongue, to the door frame. When the door closes, the flaps bend tangentially around the tongue and leave no gap (gap).

A simple way of showing the security door tongue protection device made in accordance with the present invention is that by placing flexible flaps around the lock tongue the tamper card impinges on the flaps of the device and prevents it from reaching the lock tongue to push it. opening it. And as evidenced by its use, the door becomes impregnable when it is not locked with the help of a card or other suitable breaching means. In case there are protruding screw heads around the tongue, the flat surface has a flat elongated projection with two elongated holes.

In accordance with the invention it would be desirable for the security door tongue guard to have more or less flexible flaps than three wide and eight narrow. And instead of the double-sided adhesive tape, as a means of gluing the component to the door frame. Other adhesives can be used, such as glue or screws.

The two figures numbered 1 show a simple security door tongue guard in front-section and top view.

The two figures numbered 2 show a security door tongue protection part with a projection with two holes in front-section and plan view.

The two figures numbered 3 show a safety door tongue protection part fitted to its casement

of the door when it is open.

Figure number 4 shows a security door tongue guard fitted to the door frame with a tamper card when the door is closed.

An embodiment of the invention is described with reference to the drawings. The safety door tongue protection part consists of a flat rectangular-shaped surface (of sufficient thickness) (2), with a rectangular notch (3), which on one surface has two or three wide ones (1), and eight narrower ones- (13) , (under dial 45 degrees) (10), flexible fins. While on the other side of the flat surface (2), it has a double-sided adhesive tape (7) attached to its entire length. In special cases, the surface (2) has a flat elongated projection (11), with two elongated holes (8). The security door tongue protection part is connected around the socket-hole (12), the tongue (6), the frame (5), with the help of the double-sided adhesive tape (7). And when the door (4) closes, the flaps (1,13) bend and leave no empty space (gap) around the tongue (6) for the card (9) to pass through.

In the designs shown here, three wide and eight inclined flexible fins of the same height have been used, but the use of more or fewer flexible fins of different heights is not precluded.

Claims (3)

A X I O S E I S 1. The security door tongue protection component consists of a rectangular flat (sufficient thickness) surface (2), with a rectangular notch (3), which on one side has two or three wide ones (1), and eight narrower ones (13), flexible inclined (at an angle of 45 degrees) (10), flaps and on the other side of it is attached a double-sided adhesive tape (7), which is adjusted with it around the socket-hole (12), the tongue (6), (the lock ) on the casement frame (5), of the safety door (4). 2. The security door tongue protection part according to claim 1 is characterized in that all the flexible flaps (1,13) are under 45 degree call (10), (out of operation) while when the door (4) is closed they are bent - tangents around the tongue (6), preventing the card (9) from passing - opening it. The fins (1,13) may have the same or different height and width, but at equal or different distances between them. 3. The security door tongue protection component according to claim 1,2 is characterized in that the flat surface (2), in special cases is extended by a long narrow rectangular flat surface of the same thickness (11), which has two elongated holes (8) , to adapt the accessory in cases where there are in the space around the receiving hole (12), the tongue (6), protruding screw heads.
