Description

The invention relates to the field of construction, and in particular to locking devices, for example, for windows or doors containing a fixed frame and a leaf movable relative to the frame and providing the function of forced ventilation of the room.

Known locking and ventilation device for windows and doors [patent RU 2159395]. The device is positioned to be biased between the sash frame and the separate frame by sealing strips that are located on all sides of the frame between the frame beams and independently with the help of the actuator can be pushed in and out in the plane of the window or frame and at the same time open the air gap between beams of frames. To make such ventilation devices more convenient in use, it is provided that each actuator of each sealing lining or strip is connected through a valve with all other actuators with the possibility of a drive, as well as the possibility of opening or closing an air gap using a common valve drive. Actuators have several, however, at least three switching positions.

However, the proposed device is laborious in manufacturing and installation, contains many parts.

Also known is a fitting for slightly opening and turning the sash of a window, door, etc. [patent EP 0070922], providing forced ventilation of the room and allowing to fix the window in several positions: closed, ventilation position and open position. When the sash moves from one position to another, a certain position of the roller in the fixing bar is selected.

However, this fitting is a device that provides only the forced ventilation function; it is installed separately, which complicates the assembly of the window.

Closest to the claimed solution is the reciprocal of the roller locking device of the company Roto FRANK AG [Advertising product catalog of the company Roto FRANK AG. Swivel and tilt fittings. Assembly instruction. Windows and balcony doors made of PVC, 2003], used to fix the window in the closed position. The bar is made in the form of a volumetric profiled part with a hole for fixing to a fixed frame. The front and rear surfaces of the part are made flat, while the rear surface is associated with two curvilinear sections symmetrically located relative to the transverse axis of the part in the form of recesses for the shutter roller. One of the side surfaces is provided with a longitudinal protrusion for placement in the groove of the profile of the fixed frame.

This device performs the function of a locking device, but does not provide forced ventilation of air in the room.

The objective of the invention is to provide an easy-to-manufacture locking device, which makes it possible to force the room to be ventilated when opening and closing a window that is rotated with respect to the vertical axis.

The essence of the invention lies in the fact that in the strike plate of the roller locking device for window or door blocks, including a fixed frame and a movable leaf, made in the form of a volumetric profiled part with a hole for fixing to the fixed frame, the front and rear surfaces of the part have flat sections, with this rear surface is associated with two curved sections symmetrically located relative to the transverse axis of the part under the roller of the locking device, one of the side surfaces is provided a longitudinal protrusion for placement in a fixed frame, according to the invention, the strip has a protruding part mating with the front surface and having recesses for the locking device roller symmetrically located relative to the transverse axis of the part, while the dimensions of the protruding part are selected from the condition of its placement between the fixed frame and the movable sash in the closed position of the latter and ensuring a ventilation gap in the "forced ventilation" position.

In addition, the depth of the recess in the protruding part of the strap is made corresponding to the magnitude of the approach roller of the locking device.

In addition, the movable sash in the area of interaction with the protruding part of the strike plate is provided with a groove for accommodating the latter. The protruding part of the reciprocal strips from the side of the roller at the ends can be equipped with chamfers or fillets.

The bar is made in the form of an integral part by milling or casting.

The technical result of the proposed solution is the creation of a device that provides, along with reliable fixation of the roller of the locking device in its reciprocal level, forced ventilation of the room. Ventilation is carried out through the gap between the fixed frame and the movable sash, created by the claimed device.

The device is illustrated by drawings, where FIG. 1 is a top view of the inventive device, FIG. 2 is a side view of the device from the side of the fixed frame, FIG. 3 is a rear view, FIG. 4 is a side view from the side of the movable door. Positions 1-8 in the drawings indicated:

The strike plate is part of a roller locking device intended for use in window or door blocks, mainly made of PVC profile. As a rule, window and door blocks include a fixed frame and a movable leaf, while the reciprocal strip of the roller locking device is fixed to the fixed frame, and the roller mechanism of the locking device is placed on the movable leaf. The reciprocal level represents the volume pro-thinned-out detail. The lateral surface of the part 1 on the side of the movable sash is made flat. The flat rear surface 6 is associated with two curved sections 4 under the roller of the locking device symmetrically located relative to the transverse axis of the part. The lateral surface in contact with the fixed frame is provided with a longitudinal protrusion 7 for positioning the bar in the profile groove of the fixed frame. The longitudinal protrusion 7 is made with dimensions equal in width to the width of the groove profile of the fixed frame, in depth not exceeding the depth of the groove. The geometry of the longitudinal protrusion 7 provides additional fixation of the strap on a fixed frame. Thus, the strip has a protruding part 2, conjugated with the front surface of the strip. In the protruding part 2 symmetrically with respect to the horizontal axis, curved sections 4 are made, forming together with the flat sections of the front surface of the recess 3 under the roller of the locking device. The width of the recesses is determined by the diameter of the roller, the depth of the recesses is selected taking into account the full entry of the roller into the reciprocal bar. The width of the protruding part 2 is determined by the gap between the front surface of the fixed frame and the overlapping part of the movable sash when the latter is closed. The overlapping part of the movable PVC casement is a hollow box-shaped profile, in the wall of which a groove is made on the side of the strike plate for the protruding part 2 of the strip to enter when the window or door is closed. The strap has a through hole 5 located on its transverse axis for attachment to a fixed frame. The perimeter hole 5 is made by “countersinking”, determined by the size of the head of the screw securing the bar. The bar on the inlet side of the roller at the ends is equipped with chamfers or roundings 8. The reciprocal bar is symmetrical about the transverse axis of the part passing through the center of the hole 5. This design solution allows you to install the inventive part on a fixed frame as on the right side of the window when opening the movable shutter to the left side, and on the left side of the fixed frame when opening the movable sash to the right side. The bar can be made by milling from a single piece or by casting.

The claimed invention works as follows.

The device is fixed on a fixed frame by placing a longitudinal protrusion 7 in the profile groove, and fixed with a screw. The plank provides two possible fixed positions of the movable leaf: the “closed” position and the “forced ventilation”. With the “closed” position of the window, the roller of the locking mechanism is located in a recess from the rear surface of the reciprocal plate. In the "forced ventilation" position, the roller is placed in the recess 3 of the protruding part 2 of the reciprocal strip, providing a gap between the fixed frame and the movable sash. These provisions provide reliable fixation of the locking device roller in the strike plate and, accordingly, reliable fixation of the movable sash. If necessary, change the position of the movable leaf by turning the handle of the locking device, the roller is disengaged from the reciprocal bar.

Example.

A reciprocal plate for the locking mechanism of the roller type, mounted on the window and door blocks from PVC, was made. The reciprocal level was made by milling a single piece of stainless steel. The workpiece was selected with the following overall dimensions: 55 × 25 × 11 mm (length, width, thickness). The width of the recess of the protruding part of the strap under the roller corresponded to the diameter of the roller and amounted to 11.5 mm, the depth of the recesses was 20 mm. The width of the longitudinal protrusion was 4 mm, the depth was 3 mm. The width of the protruding part of the strap was 14 mm, the thickness was 5 mm, the diameter of the mounting hole was 4 mm. The manufactured device provides a gap between the fixed frame and the movable sash for forced ventilation of a room of 14 mm. The device provides rigid fixation of the movable sash relatively motionless both during forced ventilation and in the closed position. One of the additional advantages of the claimed reciprocal strip is its versatility and interchangeability with the standard strip, which is currently used in locking devices located on window and door blocks, such as PVC.
