RU37737U1 - SHAPED PROFILE FOR VENTILATION GRILLES - Google Patents

Description

Shaped profile for ventilation grilles

A useful model for civil housing, in particular for supply and exhaust ventilation and its device.

The profile profile containing shelves selected by the applicant as the closest analogue (prototype) is already known (see RF patent No. 2136407, publ. 09/10/1999)

A disadvantage of the known profile is the high cost and material consumption, as well as low reliability.

The objective of the claimed utility model is aimed at improving reliability and simplifying the design.

The objective of the claimed utility model is achieved due to the fact that the shaped profile for ventilation grills containing the first shelf with two L-shaped perpendicular longitudinal protrusions, conjugate their racks to the inner surface of the first shelf, the second shelf, perpendicular to the first shelf and the connecting shelf, conjugated by its ends with the ends of the first shelf and the second shelf, and the connecting shelf is placed at an angle to the first and second shelves, at the junctions of the ends of the connecting shelf with the ends of the first and Ora shelves are made rounded projections for welding, the free end of the first profile flange folded inwardly, free L-shaped shelves perpendicular longitudinal protrusions facing each other, and as a profile producing material used aluminum or aluminum alloys.

IPC E04B1 / 70, F24F13 / 08

in the cross section of the profile, the connecting shelf can be placed at an angle of 45 ° to the first and second shelves, the distance A between the edge of the end of the bent free end of the first shelf and the outer surface of the second shelf can be in the range 73 mm ± 5.0 mm, distance B - between the free end of the second shelf and the outer surface of the first shelf can be in the range of 53 mm ± 5.0 mm, distance C - between the edge of the end of the bent free end and the end of the first shelf mated to the end of the connecting shelf, can be in the interval le 35 mm ± 5.0 mm, and the distance D between the inner surfaces of the uprights of the L-shaped perpendicular longitudinal protrusions may be in the range of 12.5 mm ± 5.0

In FIG. 1 shows a profile for ventilation grilles.

The shaped profile for ventilation grilles contains a first shelf 1 with two F-shaped perpendicular longitudinal protrusions 2, conjugated by their posts 3 with the inner surface 4 of the first shelf 1, a second shelf 5, perpendicular to the first shelf 1 and a connecting shelf 6, conjugated by its ends with the ends of the first shelf 1 and the second shelf 5. The connecting shelf 6 is placed at an angle to the first and second shelves 1 and 5. In the places of mating the ends of the connecting shelf 6 with the ends of the first and second shelves 1 and 5, rounded projections 7 for welding are made. The free end 8 of the first shelf 1 is bent into the profile, and the free shelves 9 of the L-shaped perpendicular longitudinal protrusions 2 are facing each other. As the material for manufacturing the profile, aluminum or aluminum alloys are used. In the cross section of the profile, the connecting shelf 6 can be placed at an angle of 45 ° to the first and second shelves 1 and 5, the distance A between the edge of the end of the bent free end 8 of the first shelf 1 and the outer surface of the second shelf 5 can be in the range of 73 mm ± 5.0 mm, distance B - between the free end of the second shelf 5 and the outer surface of the first

flange 1 may be in the range of 53 mm ± 5.0 mm, the distance C between the edge of the end face of the bent free end 8 and the end face of the first shelf 1, conjugated with the end face of the connecting shelf 6, may be in the range of 35 mm ± 5.0 mm, and the distance D between the inner surfaces of the uprights 3 of the L-shaped perpendicular longitudinal protrusions 2 may be in the range of 12.5 mm + 5.0 mm.

The manufacture of the shaped profile is carried out on standard equipment by pressing. From the shaped profile, a frame is made, which is part of the ventilation grilles.
