A method and a device for locking up of two doors

Abstract

This invention is related to the field of mechanics. The two door enchaining lock consists of a locking mechanism (1), deflection insert (2) fixed on to one door (3). A door connection cylinder (4) with hooks (5) is screwed into the deflection insert (2). The bearing part with inner thread (6) is fixed to other doors (7). In the inner part of the door connection cylinder (4) hooks (5) for fastening there is a regulation insert (8) with grooves (9) and its loops are screwed into a bearing part (6). The check-nut (10) is used for the suitable engagement of a cylinder-insert adjustment and fastening depending on the distance between the doors (3) and (7). When the doors (7) and (3) are closed, the door connection cylinder (4) engages with a regulation insert (8), the cylinder (4) hooks (5) move over the grooves (9) of the regulating insert (8), and, after turning the cylinder (4), its hooks (5), fix in the loops of the regulation insert (8) grooves (9). Two doors are chained by 1-5 devices (locks) not to the casing, but to each other.

The invention relates to the field of mechanics, namely door locks.

A known lock is comprised of an outer cylinder block having an outer cylinder. The outer cylinder has an upper surface and a housing with a concealed opening for the fastener. The outer cylinder enters the opening of the outer anvil. The lock also consists of an inner cylindrical block connected by a fastening element to an outer cylindrical block and an inner cylinder with an upper flange part and a housing. The housing has a groove for the fastener. The sleeve is fitted on the inner cylinder. The inner sleeve has an opening that includes the sleeve and the inner cylinder. The cap closes the upper part of the inner cylinder with fastener. (see U.S. Patent No. 535I5I3, TPK E 05 B 9/10).

The known lock consists of a housing, I and 2 locking mechanism. The locking mechanism I which moves the latch in the closed position is locked by the locking mechanism 2 located in the housing. Both locking mechanisms are controlled by a single key. The locking mechanism I has a rotating D-shaped disc with a flat edge, which interacts with the first moving plate. 2 the locking mechanism prevents the movable plate from moving away from the disk, and thus the locking mechanism I is held in the locked position, (see US Patent No. 5339659, TPK S C5 B 63/14) »

Known locks are only suitable for single door locking. Their construction is complicated.

The object of the invention is to simplify the construction and extend the functional possibilities.

It is an object of the present invention that a two-door locking device (lock) consisting of a cylindrical part and a locking mechanism consists of a guide sleeve on which a door connecting cylinder is screwed, mounted and secured on one door, a threaded part mounted on another door, adjustable sleeves with grooves and their eyelets on the inside for locking the cylinder hooks and counter-nuts on the sleeve for continuous support and locking of the cylinder-adjusting sleeve coupling distance, and the door connecting cylinder has openings for locking elements of the locking mechanism.

It is also an essence of the invention that in a two-door locking method using double locking and locking with two elements, when the door is closed, the door connecting cylinder engages with the adjusting sleeve, and the hooks of the cylinder loops.

The essence of the invention is also that in a two-door locking method, two doors are locked by 1-5 devices (locks) not with the frame but with each other.

The invention is illustrated in the drawings.

Pig.I - two door locking device (lock). Fig. 2 is a sectional view of the adjusting sleeve. Fig. 3 is a sectional view of the door connecting cylinder and adjusting sleeve.

The two-door locking device (lock) consists of a locking mechanism I, the guide sleeve 2 secured in one door 3. The door sleeve cylinder 4 with hooks 5 is screwed into the guide sleeve 2. bushing 8 with grooves 9 and their eyelets on the inside for locking the hooks 5 of the door connecting cylinder 4. A lock nut 10 is provided for adjusting and locking the proper cylinder-adjusting sleeve engagement distance, which is determined by the distance between the doors 3 and 7.

Before locking the key locking mechanism I closes the door 3, 7. The door connecting cylinder 4 moves horizontally when the door 3 is closed and enters the adjusting sleeve 8, whose grooves 9 slide through the hooks 5 of the door connecting cylinder 4. 8 grooves in 9 loops, and locking meLT 4589 B

turning the cylinder 4 in any direction is impossible when the door is locked with the I key of the chanism. The locking elements of the locking mechanism I, the latch, the tongue (not shown in the drawing), enter the openings in the cylinder 4. With the key unlocking the locking mechanism I and the door at the same time, the door connecting cylinder 4 is turned so that the hooks 5 come out of the slots 9 of the grooves 9 of the regulating sleeve 8. When opening the door 3 the hooks 5 of the cylinder 4 exit the grooves of the adjusting sleeve 8 · This disengages the cylinder 4 from the adjusting sleeve 8. When the door is fitted with a locking device, locks the cylinder-adjusting sleeve in a steady position. 3 and 7. This position is adjusted by lock nut 10 and provides stability in the adjusted position.

The claimed invention has a simple construction. The parts of the device are simple and made by stamping or molding metal. The unit comes with a small amount of parts. By means of the present invention, two doors are locked into one another at the same time, rather than in the frame. That is, they are combined into a single, solid structure, which reduces the risk of breaking the door and enhances their safety.
