Изобретение относитс к устройству, в частности к замку, который может быть использован, дл запирани дверей в помещени х.The invention relates to a device, in particular to a lock that can be used to lock doors in rooms.

Известен замок, содержащий корпус, ригель с установленной на нем подпружиненной цугальтой, ключевой запирающий механизм и ручку с поводком, имеющим запорные кулачки и 4нксирующие высту 1 1Данный замок вл етс наиболее блиэким к изобретению по технической сущности и достигаемому результату.A lock is known, comprising a housing, a bolt with spring-loaded zugalta installed on it, a key locking mechanism and a handle with a leash having locking cams and 4 openings 1 1 This lock is the closest to the invention according to its technical essence and the achieved result.

Недостатком известного замка вл етс неудобство в пользовании им, заключа щеес в том, что при защ тван1га замка снаружи ключом до упора невозможно открыть его изнутри, так как фиксирующий выступ упираетс в выступ ригел , что не дает возможностн поводку войти в зацепление с ригелем.A disadvantage of the known lock is the inconvenience of using it, which is that when the lock is secured with the key from the outside, it is impossible to open it from the inside all the way, because the locking protrusion rests against the bolt protrusion, which does not allow the leash to engage with the transom.

Целью изобретени вл етс повышение удобства пользовани замком.The aim of the invention is to improve the usability of the lock.

Дл того в предлагаемом замке ригель имеет подпружиненную пластину, установленную на его торце с возможностью взаимодействи с фиксируюшими выступами поводка ручки.In addition, in the proposed lock, the bolt has a spring-loaded plate mounted on its end face with the possibility of interacting with the locking protrusions of the leash of the handle.

На фиг. 1 изображен общий вид замка , разрез (открытое положение); на фиг. 2 - разрез по Б-Б на Фиг. 1; на фиг. 3 - замок в положении, закрытом ручкой; на фиг. 4 - то же, в положении закрытом ключом.FIG. 1 shows a general view of the lock, a section (open position); in fig. 2 is a section along BB in FIG. one; in fig. 3 - lock in the position closed by the handle; in fig. 4 - the same, in the closed key position.

Замок содержит корпус 1 с крышксй 2, в котором установлен ключевой запирающий механизм 3, имекший поводок 4 дл запирани замка снаружи посредством ключа и соосно расположенную ручку 5 с поводком 6 дл запирани замка изнутри помещени . Поводок 6 имеет два запорных кулачка 7 и два фиксирующих выступа В, а ригель 9 имеет штифт 1О, на котором расположена подпружиненна цугальта 11, при :-,этом в нижней части ригел выполнены пазы 12 со скошенными поверхност ми.The lock includes a housing 1 with a lid 2, in which a key locking mechanism 3 is installed, having a leash 4 for locking the lock from the outside with a key and a coaxially positioned handle 5 with a leash 6 for locking the lock from inside the room. The leash 6 has two locking cams 7 and two locking projections B, and the bolt 9 has a pin 1O on which spring-loaded zugalt 11 is located, with: -, this has grooves 12 with beveled surfaces in the lower part of the bolt.

Claims

The bolt 9 has a spring-loaded plate 13 mounted on its end with the ability to vidamodeystvii (ixory protrusions 8 of the leash 6 handles 5. The locking protrusions 8 of the leash 6 are displaced at the same angle relative to his cams 7. The lock follows in the same way. When closing the lock from the inside, put the handle 5 turn the associated leash 6 clockwise, which, by hooking the cams 7 to the dead bolt 9, pushes etx) to the extreme locked position. In this position, one of the locking protrusions 8 of the pivot 6 abuts against the protruding spring plate 13, limiting the handle rotation and preventing the driver from coming out of engagement with the bolt, and the flat surface of the transom is located tangentially to the rounded portion of the driver 6, the center of curvature of which is on the axis rotation of the leash. When attempting to release a lock with a key: outside, the leash 4 tends to move the bolt into position. The latter acts on the leash 6 of the handle with some force, but in this position the normal reaction is directed to the center of curvature of the rounded portion of the cam lying on its axis of rotation and does not create a torque that turns the driving leash 6 of the handle. In this position, the handle of the handle excludes its turn with a key. Unlocking the lock from the inside of the room when the lock is closed with a key, follows the dial. When the knob 5 is rotated counterclockwise, the leash b rests against the protruding spring plate 13 with one locking protrusion 8 and bends it at a certain angle. When the driver turns further, the locking protrusion 8 slides off, the spring plate returns to its original position, and the leash 6 engages with the bolt and opens the lock. The presence of a protruding spring-loaded plate on the crossbar, improves the consumer qualities of the lock in use. Claims of Invention A lock comprising a body, a bolt with a spring-loaded zugalta installed on it, a key locking mechanism and a handle with a leash having locking cams and "{spread out the protrusions, which is free from the fact that the bolt has a spring-loaded a plate mounted on its face with the ability to interact with the locking protrusions of the leash of the handle.
