The device for closing the front opening consists of a fixing frame 1, a movable shutter 2, a supporting lower guide 3 and a holding upper guide 4 (Fig. 15, 16). Frame 1 is made of steel and is rigidly fixed in a lockable opening. In the closed position, the frame 1 holds the shutter 2 by means of a latch bolt lock 5 mounted on the shutter 2, and a slot 6 made in the frame 1 (Fig. 13). The guides 3, 4 are attached to the wall with the help of corners of the required size and strength. When the shutter rests on the lower support rail 3, the upper guide 4 is not bearing, it only supports the shutter 2, ensuring its movement along the path defined by the lower guide 3 (Fig. 16).

The shutter 2 is mounted on the supporting rotary levers 7, · pivotally mounted at one end in the shutter 2, and the other - the support carriage 8, moving along the groove in the lower guide 3 (Fig. 1, 2, 11, 15, 16). The levers 7 are mounted on the support carriage 8 using the supporting metal bolts 9 (Fig. 4, 5). At the front end of the pivoting arms 7, a support sleeve 22 is installed with the possibility of entering the cutout guide plates 16, which are attached to the guides 3 or 4, as well as to the fixing frame 1 (Fig. 11) installed inside the closable facade opening. At the bottom of the groove in the lower guide 3, as well as in its upper part, is a tape 10 made of plastic with a low coefficient of friction, for example, fluoroplastic, high molecular weight polyethylene, etc. (Fig. 4), while the carriage is equipped with metal knives (Fig. 3, 4, 6 '). The carriage 8 may be provided with bearing rollers 11, moving along the ribs of the guide 3 (Fig. 5, 6), the tape 10 in this case is not needed (Fig.5-6). Rollers 11 in the amount of 4 pieces are installed in pairs on both sides of the carriage 8 (Fig. 6 '). The carriage 8 can be equipped with curly plates 28 made of a material with a low coefficient of friction (fluoroplastic, low-pressure polyethylene, etc.), allowing the carriage to slide along the edges of the guide 3 or 4 (Fig. 6 '). The ribs installed on the bottom of the guide profile prevents the carriage of the supporting ribs from coming off.

When the shutter is supported on the lower support rail 3 from above, the shutter 2 is held by pivoting arms 13 pivotally mounted at one end in the shutter 2 and the other through the bracket 14 on the guide sleeve 15 moving along horizontal (Fig. 7-8) or vertical (Fig. 8). 7-10) a groove in the upper guide 4, while on the upper side of the pivot arm 7, a carrier plate 27 (FIG. 5) can be mounted to support the shutter 2 on it. The shutter 2 contains support pins 21, mounted with the possibility of entry into the grooves 6, made in the fixing frame 1 (Fig. 12, 13).

In the grooves 6 of the fixing frame 1 can be installed spring-loaded latches 5 (Fig. 13).

An additional movable carriage 23 can be mounted on the upper guide 4, having a bracket 24, which can be hooked up to the bracket 25 of the protective shutter 2 (Fig. 11).

On the protective shutter 2 can be fixed bolt lock 19, the bolts 18 of which are able to enter the holes 20 of the locking frame 1 (Fig. 5, 14).

The fixing frame 2 can be structurally combined with a window frame located in the facade opening.

The shutter may be single or composite. In the case of a composite shutter, the second part is attached to the sliding shutter 2 on the hinges, the third part is similarly attached to the second, etc. A composite shutter allows you to block a large opening (for example, terrace windows), while reducing the size of its constituent elements.

The proposed device operates as follows. In the open position (Fig. 1), the shutter is located along the wall, being fixed through the pivoting levers 7 and the movable carriages 8 (Fig. 3, Fig. 4) on the guides 3 or 4, which are mounted on the wall above and below the facade opening. When closing the front opening (Fig. 2), the shutter moves together with the pivoting levers and pivotally connected to them movable carriages in the direction of the closed facade opening.

After the protective shutter approaches the opening, by applying force to the rear ends of the levers 7, the support sleeves 22, mounted on the front end of the rotary levers 7, enter the cutout of the guide plate 28. The guide plates are fixed on the guides 3 or 4 and on the locking frame 1.

Due to the fact that the rear shoulders of the levers 7 are connected by a rod 17, the length of which is equal to the distance between the attachment points of the front shoulders, a trapezoid is formed and the front shoulder of the rear lever repeats the trajectory of the front shoulder of the front lever. In this case, the rear lever sleeve 22 enters the cutout of the guide plate 16. The movement of the front ends of the levers along the cutouts of the guide plates leads to the shutter 2 moving into the front opening with the shutter 2 being fixed in the frame 1. An additional movable carriage 23 ensures the safety of the protective shutter on the supporting profile behind the engagement of the brackets 24 and 25, taking on the weight of the shutter (Fig.

I I).

If the front shoulders of the levers 7 are directed counterclockwise, then the shutter 2 moves so (figure 2, sequential positions I, II,

III): after the shutter 2 occupies a position opposite the opening, due to the pressure on the rear shoulders of the levers 7 towards each other, they begin to turn, and their front shoulders and the shutter 2 fixed to them slide into the opening. The front shoulders of the levers 7 move along the stoppers 16, which ensures that the shutter 2 enters the frame 1. The attachment point of both levers 7 on the shutter 2 is separated from the edge by a distance sufficient to when moving into the opening, the side of the levers 7 did not abut the corners of the opening. This distance is determined by the depth of movement of the shutter 2 and the distance from the guide 3 to the wall (Fig. 1, 2).

After moving the shutter 2 into the frame 1, the support pins 21 of the shutter enter the grooves 6 of the frame with the fixing of the support pins in the shutter 1 using spring-loaded latches 5.

The shutter 2 is locked in the fixing frame 1 by entering the bolts 18 of the lock 19, mounted on the protective shutter 2 in the holes 20 of the fixing frame 1 (Fig. 14, 16). In the closed position, the load of the weight of the protective shutter 1 is fully carried by the fixing frame 7.

EMBODIMENTS FOR CARRYING OUT THE INVENTION.

In the manufacture of the proposed device, it is preferable to use the following main parts.

Shutter 2 - the size and material are determined by the size of the opening to be closed and the customer's requirements for strength and appearance.

Guides 3, 4 - galvanized steel profile C-shaped with a longitudinal groove along the entire length of the upper side. The profile can also be made of stainless steel. With an increase in the weight of the shutter 2, the section of the profile and the thickness of its wall increase.

Brackets for fastening guides 3, 4 - a corner from galvanized steel. The length of the upper shelf of the corner is determined by the distance by which the guide should be carried away from the wall; an elongated adjustment hole is made in it. With increasing weight, shutters 2 can be increased the side shelf of the corner and / or its thickness, but the best solution would be to use a corner with an internal stiffener.

The carriage 8 is a three-dimensional metal part made by casting of an aluminum alloy (Fig. 6 '). On the axes of the carriage are attached two knives 8 '. Rollers 11 can also be mounted on the axes. On the sides of the carriage 8, guides to the ribs of the guides can be fixed, shaped overlays made of a material with a low coefficient of friction (PTFE, low-pressure polyethylene, etc.).

The rotary lever 7 is installed in the carriage 8 due to the threaded connection with its bolt 9 (Fig. 3, 4, 5, 6, 6 ").

The tape 10 is fixed on the bottom (or in the upper part) of the guide 3, is removable and is replaced in case of wear. The tape 10 can be mounted on an easily removable metal strip.

The metal rod 17, connecting the levers 7 and ensuring the synchronization of their rotation, can be made of a metal strip with a stiffener.

The upper swivel-sliding mechanism is a carriage with wheels or bushings made of plastic with a low coefficient that slide freely along the vertical or horizontal groove of the guide 4. To them, through the brackets 14, levers 13 are pivotally mounted, the second end freely attached to the upper side of the shutter 2.

The locking mechanism of the shutter 2 in the frame 1 is a lock in the form of a spring-loaded latch 5 locking pin 21 of the shutter 2. The locking mechanism of the shutter 2 in the frame 1 - crossbars 18 of the bolt lock 19 installed in the shutter 2 included in the reciprocal slot 20 in the form of an opening in the frame 1.

INDUSTRIAL APPLICABILITY

Due to the design described, in the proposed device, the unit that provides the movement of the shutter 2 along the guide 3 does not bear additional load (except for the weight of the shutter 2 itself), and from the moment the shutter 2 is fixed in the frame 1, the whole load is borne by the frame 1, the pins in the frame slots are fixed spring-loaded latches 5 and bolts 18 of the lock 19, i.e. according to load distribution, the proposed device is similar to the door leaf in the door frame at the time of its locking. Due to this, the proposed device provides the highest protection for a window, door or other facade opening similar to the protection that the front door provides.
