Description

The utility model relates to the equipment of special-purpose doors, namely, cameras of sensitive objects for holding suspects or convicts.

Known window for the transmission of food, made in the chamber door, equipped with a hinge hinged to the chamber door with a locking device, http://images.yandex.ru/search?p=20&text=%... (copy of the link attached).

The disadvantage of this design is its unreliability due to the possibility of unlocking the locking device from the inside of the camera using a thin sharp object, pushed into the gap between the flap and the window frame.

There is also known a window for food transmission, made in the chamber door, provided with a sash pivotally attached to the chamber door with an overhead locking device with one or more locking elements, http://bulat-dveri.narod.ru/spezprod1.html (a copy of the link is attached) .

This technical solution was adopted as a prototype of this utility model.

Its disadvantage, as well as the above analogue, is unreliability due to the possibility of opening the flap from the inside of the chamber; in addition, it is impossible to quickly lock the window sash in an emergency, since for this you need to not only block the window opening with the sash, but also turn the key in the locking device (lock); there is no possibility of fixing the flap in a horizontal position during food transfer.

The objective of this utility model is to increase the reliability of closing the window for food transmission, providing the ability to quickly lock the flap during emergency closure of the window opening, as well as providing the possibility of fixing the sash in a horizontal position during food transfer.

According to a utility model, a food delivery window is provided in a chamber door provided with a hinge pivotally attached thereto with a locking device with one or more locking elements, new is that a rigid box-shaped element is fixed on the flap on the side of the window, the dimensions of which correspond to the dimensions the window opening, the locking device is placed in a hollow body mounted on the flap on the opposite side to the box element, the locking device is provided with an additional recording The connecting element, made in the form of an unequal lever balancer, coupled to the body by means of a hinge located in it, the axis of rotation of which is perpendicular to the flap, has a window in the side wall of the body in which the short arm of the lever balancer is placed, a counterweight is fixed on the long arm of the lever balancer, on the surface of the chamber door is fixed emphasis with a beveled edge and a recess, while the emphasis is fixed on the surface of the door with the possibility of placing a short arm of the lever balancer in the recess emphasis; the flap of the window is equipped with a telescopic mechanism made with the possibility of fixing the flap in a horizontal position.

The applicant has not identified sources containing information about technical solutions identical to this utility model, which allows us to conclude that it meets the criterion of "Novelty."

The essence of the utility model is illustrated by drawings, which depict:

figure 1 - window in the open position, the flap is in a horizontal position (axonometry);

figure 2 is a view along arrow "A" in figure 1;

figure 3 - window in the closed position (axonometry);

figure 4 is a view along arrow "B" in figure 3;

figure 5 is a section bb in figure 4;

in Fig.6 - node G in Fig.5 on an enlarged scale.

The window for food transfer is made in the chamber door 1 and is equipped with a sash 2 pivotally attached to it with a locking device; in this example, the locking device has two locking elements 3, which are retractable crossbars. A rigid box-shaped element 4 is fixed on the flap 2 from the side of the window; its dimensions correspond to the dimensions of the opening 5 of the window. The locking device is placed in a hollow body 6, mounted on a flap 2 from the opposite side relative to the box element 4. The locking device is equipped with an additional locking element 3, made in the form of unequal lever balancer 9, coupled with the housing 6 by means of the hinge 10 placed therein. The axis of rotation of the hinge 10 is perpendicular to the flap 2. A hole 12 is made in the side wall 11 of the housing 6, in which a short shoulder of the lever balancer 9. On the long shoulder of the lever balancer 9, a counterweight 13 is strengthened; an emphasis 14 is made on the surface of the chamber door 1, made with a beveled face 15 and a recess 16 with the possibility of placing a short arm of the lever balance 9 in the recess 16 of the stop 14. The flap 2 is equipped with a telescopic mechanism - a telescopic rod 17, which is capable of fixing the 2-fold flap horizontal position. One end of the telescopic rod 17 is pivotally attached to the flap 2, and its other end is pivotally attached to the chamber door 1.

On the chamber door 1, on both sides of the window opening 5, tubular elements 7 are placed for introducing the locking elements 3. The reciprocating movement of the locking elements 3 is carried out by means of a drive comprising a disk 8, rigidly connected to an axis 18 mounted for rotation in the housing 6. The end of the axis 18 is made curly, for example, hexagonal; the axis 18 and the disk 8 are rotated using a socket wrench of the corresponding shape. The end of the axis 18 is closed by a protective casing 19 to prevent unauthorized mechanical impact on the axis 18.

The device operates as follows. In the open position (FIGS. 1, 2), the flap 2 is in a horizontal position, the telescopic rod 17 is folded and fixes the flap 2. On the surface of the rigid box-shaped element 4 put dishes with food that can be taken out of the camera through the opening 5 of the window. In this case, direct contact of persons in the cell with personnel involved in the transfer of food is excluded. To close the window, the flap 2 is lifted with one hand (the second hand is free) and pressed against the window opening 5. The box-shaped element 4 enters with a small gap in the opening 5 of the window. In this case, the short (outer) end of the unequal lever balancer 9 interacts with the beveled face 15 of the stop 14 and, under the action of the counterweight 13, enters the recess 16, fixing the hinge 2 in the closed position. Thus, the preliminary fixation of the flap 2 in the closed position can be carried out quickly, with one movement of the hand, without using a locking device with locking elements 3, which is very important in an emergency. After that, with the help of a key, the axis 18 is rotated with the disk 8, the locking elements 3 are extended, and they are inserted into the tubular elements 7, making the final reliable closing of the window. Opening the window is carried out in the reverse order, while the end of the lever balancer 9 is removed from the recess 16 of the stop 14 by pressing it with a hand.

Due to the presence on the inner (from the camera side) side of the sash 2 of the rigid box-like element 4 and the locking device on the opposite side of the sash 2, it is not possible for objects to act on it from the camera side through the gap between the sash 2 and the lining of the window opening 5.

For the manufacture of the device used conventional structural materials and factory equipment. This circumstance, according to the applicant, allows us to conclude that this utility model meets the criterion of "Industrial applicability".
