RU87741U1 - WINDOW LATCH BLOCKER WITH EMERGENCY OPENING MECHANISM FOR EVACUATION - Google Patents

Abstract

1. Window lattice blocker with an emergency opening mechanism for evacuation, comprising a lock case with a movable element, characterized in that a hole is made in the movable element, into which the movable crossbar is able to enter, and the length of the bolt exceeds the distance between the frame and the lock case. ! 2. The device according to claim 1, characterized in that a heel is fixed at the opposite end of the crossbar. ! 3. The device according to claim 2, characterized in that the bolt is spring-loaded.

Description

The proposed solution relates to construction equipment, in particular to the design of safety and locking devices and can be used to protect window openings from unauthorized entry into the room from the outside.

One of the problems of creating such safety and fixing devices is, on the one hand, the requirement of increased reliability of their functioning and the reduction of the likelihood of unauthorized entry from the outside, and on the other hand, the possibility of their quick, trouble-free opening during extreme situations (for example, fire) in order to emergency evacuation of people in the premises, and possibly material assets.

There is a device for protecting window or door openings (see RF patent for utility model No. 33388, IPC EV 06/09 of July 9, 2003) containing an opening guard with locks made in the form of anchors with support pins.

There is a fire protection device for window and door openings with an emergency opening mechanism for evacuation (see RF patent for utility model No. 68049, IPC EV 9/02 of July 10, 2007).

A disadvantage of the known devices is their complexity and, as a consequence, a decrease in the reliability of operation.

The technical solution “BK-1 Blocker” is known, which is a locking mechanism mounted on the grill of a window opening and providing locking of the grill by moving elements driven by a lever (see .80 / block.php for a prototype).

A disadvantage of the known technical solution is also complexity and, as a consequence, a decrease in the reliability of its operation.

The aim of the proposed device is to eliminate this drawback, namely, simplifying the design and improving the reliability of its operation.

This goal is achieved by the fact that in the known window grill lock with emergency opening mechanism for evacuation comprising a window frame, grill, lock case with a movable element in which, according to a utility model, an opening is made in the movable element into which the movable bolt located in a sleeve mounted on the case of constipation, and the length of the bolt exceeds the distance between the frame and the case of constipation, and at the opposite end of the bolt is fixed a heel that abuts the window frame. In addition, the bolt is spring-loaded relative to the sleeve and, consequently, the housing.

This set of features exhibits new properties consisting in the fact that thanks to just such a set, the design of the emergency opening mechanism is simplified and the reliability of its functioning is increased.

Schematic diagram of the device shown in figure 1, where:

1 - window frame;

2 - lattice;

3 - case of constipation;

4 - movable element;

5 - hole;

6 - movable crossbar;

7 - guide sleeve;

8 - heels;

9 - spring.

The window guard lock with the emergency opening mechanism for evacuation includes a window frame 1, a guard 2, on which the closure body 3 is rigidly fixed, with a movable member 4 serving to lock the guard 2. An opening 5 is made in the movable member 4, into which the movable the bolt 6 located in the guide sleeve 7. In the closed state, the length of the bolt 6 exceeds the distance between the frame 1 and the closure body 3. At the opposite end of the bolt 6 there is a heel 8, which abuts the window frame 1 in the closed state I'm into her. The crossbar 6 is spring-loaded relative to the sleeve 7 by a spring 9.

The device operates as follows.

In the closed position of the window frame 1 and the grating 2, the movable element 4 enters into the locking engagement (not shown in FIG. 1) and securely fastens the grating 2 from unauthorized opening.

When this bolt 6 under the action of the spring 9 penetrates into the hole 5 of the movable element 4, preventing the opening of the lattice of the window frame 2 from the outside. The second end of the crossbar 6, equipped with a fifth 8, abuts against the window frame 1, which is locked in the usual way, and, thus, is fixed in this position.

In the event of an emergency, such as a fire, when it becomes necessary to urgently open windows to evacuate people, and possibly valuable property, window frame 1 opens. In this case, by means of the spring 9, the crossbar 6 leaves the hole 5 of the movable element 4 thereby freeing its free travel. The movable element 4 is removed from the locking engagement and the lattice of the window frame 2 is opened, freeing the opening for evacuation.

Thus, the use of the proposed technical solution will simplify the design and increase the reliability of the operation of the device.
