SI20483A - Safety shield of building cylinder plug with movable cover - Google Patents

Abstract

A safety shield of a building cylinder plug with a movable cover prevents a direct access by force to the building cylinder plug or other locking mechanisms in the building lock assembly. The access to the cylinder is possible only by pushing away the movable cover (2) above the cylinder plug. All that matters is to insert the system (3) from the side of the movable cover (2) and a base plate (1) in the direction parallel or at an angle to the front plane of the movable cover (2). The shift of the system of hollow cylinders and pins in the axial direction enables the key ridges to press against the available surface of hollow cylinders and pins. The hollow cylinders and pins then move to the position which releases the guided movable cover in such a manner that it slides in its free direction.

Description

The invention relates to the field of mechanical protection of the locking mechanism of building cylindrical inserts and building locks.

A technical problem solved by the invention is the construction of a guard mounted on the outside of the door above the building lock or some other locking mechanism. The safety shield prevents mechanical damage to the building lock and the cylinder block insert, which covers the insert from the outside, thus protecting it from violent fracturing and drilling in the area where plugs are inserted to prevent the cylinder from rotating with the wrong key.

The hitch protection cap known so far is designed to be moved by pressing a special key on the hollow cylinder system and the stud on the front of the sliding cover. The disadvantage of this embodiment is the easy access to the hollow cylinder and plug system.

The object of the invention is the position of the hollow cylinder system and the studs (3), which are inserted into the safety shield, in parallel, Fig. 1 or obliquely with the face of the movable cover (2), Fig. 2.

The invention is described in the embodiment and in the drawings showing:

FIG. Fig. 1 shows a safety cover with a sliding cover and the position of a hollow cylinder and plug system, which are inserted parallel to the face of the sliding cover FIG. 2 shows a system of hollow cylinders and studs (3) inserted into the safety guard obliquely on the front face of the sliding cover (2) FIG. 3 shows a wrench shape with ridges which, by pressing them, move in the axial direction Fig. 4 a system of hollow cylinders and studs with the desired position.

The safety shield consists of a base plate (1), a sliding cover (2) that protects the building cylinder liner and hollow cylinders and studs (3) that are radially sectioned. They are pushed into the upper position by pressure-biased springs. For different combinations of wrenches on the wrench, the hollow cylinder (4) and the stud (5) are important, which can be altered or altered by the hollow cylinder (9) and the stud (10), Figure 2, and thus the height of the wrenches on the wrench, to move the front surfaces of the hollow cylinders and studs in the height of the sliding surface between the base (1) and the sliding cover (2), thereby allowing the sliding cover to move in the direction of the sliding surface.

The other elements in the system remain dimensionally unchanged. The notch (6) is used to guide and position the key. The threaded plug (7) limits the displacement of the lid (2) and prevents it from being dismantled when the safety guard is installed above the building lock.

It is only important that the system (3) is inserted from the side of the sliding cover (2) and the base plate (1) parallel to its face, Figure 1, or that the system (3) is inserted obliquely from the face of the sliding cover (2) ), Figure 2. One or more systems (3) may be on the left or right side of the security guard.

v

The studs (8) with an internal thread are intended for fixing the safety guard above the building lock so that it is not damaged and therefore it is possible to mount it on any type of building or other lock.

It is also important that the same key can be used to activate the displacement of the lid (2) as for the rotation of the cylinder in the building cylindrical insert, provided that it has further designed ridges for this purpose that allow the axial movement of the hollow cylinders and studs of the system (3), Fig. 3, or a special wrench with a ridge made, Fig. 4.
