BACKGROUND OF THE INVENTION The present invention relates to an additional, mechanically-operated door-locking device, which is suitable for preventing the breaking of doors and windows of doors and windows, in particular of prefabricated concrete-walled flats.

It is well-known that the number of violent intrusions is increasing when an unauthorized intruder does not (using a "professional" dummy key) enter the apartment by simply tensioning the one-point lock tongue. Optionally secured locking devices which multiply the single locking of the locking devices can provide adequate protection against these stresses.

Nowadays, the fulfillment of the two main functions of burglary protection has clearly split in modern security developments. The purpose of burglary protection is, on the one hand, the solution of individual operation (inaccessible to unauthorized persons) and, on the other hand, the provision of resistance to mechanical (violent) stresses. Robust latches (including the enormous keys) of earlier eras, which tried to fulfill the two functions in a single construction, have now been replaced by precision mechanics. or solutions that can be decoded by magnetic or even electronically encoded controls and by high-strength mechanical shielding devices operated by them.

Among the solutions used to prevent the unauthorized opening of the door and window structures by a combination of various solutions for actuation and mechanical function. nowadays they are countless. which may be additionally fitted to or supplement the existing, previously developed solution.

Patent application HU 183 965 is incorporated herein by reference. advantageously simple, relatively inexpensive fabrication, but also sufficiently secure against unauthorized entry, can be mounted on the door and can be slidably embedded in the full width of the brace which can be attached to the wall by means of an articulated link and locked in the end position. The user reluctance to apply the above (and similar, commonly known as webbing) solution is primarily due to aesthetic reasons, since the appearance of the fitted locking mechanism gives the viewer a sense of a prison cell door. In addition, the operation of the locking mechanism, although not complicated, usually requires a separate opening-closing or possibly locking operation.

Even more striking is the independent insertion of the mechanical insurance function in the Hungarian patent application H / 3272. In this embodiment, the optional tongue of the coded actuated lock, which is not part of the construction, is used to lock a mechanical rack which is movable on a gear rack principle. The solution, e.g. at the front doors of cash registers, warehouses, shops, where the double operation (the locking mechanism and the security hardware separately) is less distracting in the act of closing, it is elegantly simple and adequate, but at the front doors of apartments this double operation may be uncomfortable. At the same time, the aesthetic camouflage of the door reinforcing hardware could only be achieved by dismantling and costly remodeling the door.

They are closest to, and nearly identical in appearance to, the embodiments of the invention, as found in French Patent No. FR 86 430 031.4 and Hungarian Patent Application Publication No. H / 3407. An idea underlying the three inventions is that the locking tongue of a locking device previously installed on the door can be used to operate the safety locking tongues, which can be removed from the aesthetically fixed hardware of the door, forming reinforced cover protection. In the French construction, the locking latches can be moved by means of an articulated linkage and in the Hungarian construction by means of parallel-operated two-lever lifts, the movement of which is effected by the operation of the locking latches of a coded locking device mounted on the door.

In addition to the safety cover that can be fitted to apartment doors and windows, it is now a general requirement to provide static safety after installation and maintenance free, and last but not least, the solution is inexpensive, easy to operate and aesthetically pleasing.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a door and door security device that can be mass-produced, low-cost, in-house fitted with simple DIY tools, in particular, , it builds on the existing protection barely noticeably, and is managed in the same way as before and does not replace or replace the previous solution, but acts as a serially connected system.

The object of the present invention is to provide an additional mechanically operated door-locking device having locking tongues at several points on the longitudinal inner side of the door-opposed hinge, extending over the entire height of the door, acting as guardians, or to the concrete wall.

A feature of the door and door locking device according to the invention is that the door lock is equipped with two double-lever lifts which can be swiveled around a bolt operated by a locking tongue, each having a locking tongue movable behind the inner side of the door. at the other end of the lifts, and when they are connected to the locking latch of the intended door -

EN 211 723 Β on site - an eccentric fixed on a position-adjustable stud bolt.

The operation of the door-locking device according to the invention takes place almost simultaneously with the opening and closing of the door-mounted locking mechanism in the same operation, almost unnoticed by the user.

Illustrating the apparatus and the operation thereof according to the invention is shown in the drawings: a

Figure 1 illustrates the positioning of a door and door locking device according to the invention on a front door casing,

Figure 2 is a sectional view taken along line Π-II in Figure 1,

Figure 3 (viewed from the perspective of Figure 1) is a sectional view of the device from the plane of the door,

And Figure 4 is a sectional view of the device viewed from the door frame in a perspective view to Figure 3.

Figure 1 illustrates the door and door protection device according to the invention as a cover protection fixed to the frame of a home door, its mounted components and its working principle.

The device includes two two lever arms 3 with a locking tab 1 fixed at one end (opposed to one another), which is operable in the housing 2 of the device by means of screws 2 secured to the door frame by screws 8 on the door. At the other end of the two-arm lifts 3 (when they are connected to each other), a locking bolt 10 and an eccentric 5 are mounted on the locking bolt 8 of the door and are provided with a spring 4 retracting the locking bolts 1 when opened.

From the closed position shown in Fig. 1, when the locking tongue 8 of the actuating locking device 7 moves in the open direction (i. E. Arrowed in the figure), the eccentric 5 is unlocked and the locking tongues 1 firmly secured to the two lever arms 3 to the 2 guardians.

The locking movement of the locking tongue 8 of the actuating locking device 7 moves against the spring 4 the two-arm lifts 3 attached to the eccentric 5 as a jointly operating point, which push the locking tongues 1 firmly fixed to them from the guard.

Fig. 2 is a sectional view taken along line Π-II in Fig. 1, showing the locking latches 1 in a position in which they protrude from the inside of the door from a frame 2 secured to the door frame by a hinge screw 9.

As shown in Figures 3 and 4, it is possible to fit its eccentric 5 as an actuation point in three orthogonal directions, e.g. for locks previously fitted to a door:

Height alignment (i.e., alignment of the eccentric 5 as the actuation point with the locking tab 8 of the actuating locking mechanism 7) is possible by vertical displacement of the entire locking mechanism relative to the door.

Subsequently, by adjusting the stud bolt 10 and rotating the eccentric 5 in both directions (on the one hand, and perpendicular to the tongue 8 of the actuating locking device 7), it is possible to mount the eccentric 5 as the actuating point on the door to the 8 tongues of the previously installed latch 7.

After adjusting the exact fit and trial operation, the contoured locking plates 11 prevent further unwanted rotation of the parts moved during the fit.

Examination of a prototype of a door and door locking device according to the invention has proved the achievement of the intended objects.

It offers a solution for the most convenient and usually the most costly part of securing a door and window, tripling the single closing point. The user does not even see the triple end of the closing point in operation, he still has to do the usual closing / opening operation.

The locking device according to the invention is particularly advantageous for securing the entrance door of flats, because it can be mass-produced at low cost and can be fitted to the door locks without any special expertise, can be fitted with simple DIY tools, and provides the required protection against unwanted violent insertions. , while its appearance is aesthetic, and the appearance of the home door, which is additionally provided with a security structure, does not create the feeling of a prison lattice.

Compared to the French version of FR / 86 430 031.4, which is mentioned in the introduction, there are several advantages.

By moving the locking latches moving by the two-arm lifting mechanism of the present invention, their near-linear displacement is more robust, requiring a smaller (less weakening of the guard) bore than the locking latches pivoting from the guard.

In the construction according to the invention, the actuator lock tongue (due to the larger lever arms of the two-arm hoist) is only subjected to very low frictional forces and does not require greasing and maintenance over its long service life.

The advantage of the present invention over the version of the Hungarian Patent Application Publication No. H / 3407 cited above is that, in addition to its simplicity of manufacture, it can be installed and operated in a homemade design without requiring the modification of the door frame or the engraving of the doorbell. forming the nests of the enclosed closures. Thus, it also provides users with more limited resources with greater protection for their property. (Those who are forced to give up more expensive or higher-priced products.)
