RU2268980C2 - Venting acoustic protection device - Google Patents

Abstract

FIELD: building, particularly acoustic protection devices used in window units.

SUBSTANCE: acoustic protection device comprises hollow body with orifices and valve arranged in the body. The valve is provided with drive for valve displacement. The valve comprises at least two orifices arranged from each valve side. Device has at least one valve pair with common drive made as differential mechanism including support secured to the body, control shaft arranged in support groove to provide control shaft rotation and movement along the groove and double-armed lever. The double-armed lever has ends connected to corresponding valves through ties and hinges so that the valves may be moved into the body towards above orifices to seal vent channels made in window leaf sides.

EFFECT: increased heat and noise insulation and improved transparency.

Description

The invention relates to the field of construction, and in particular to soundproofing devices used as part of window blocks installed in building apertures, and is intended to ensure the supply of outdoor air to ventilated rooms of public and residential buildings in cases where the required mode of ventilation through windows, transoms or narrow casement windows cannot be used due to the need to comply with regulatory requirements for penetrating noise.

From the prior art it is known ventilation soundproofing device containing a hollow body, on the opposite walls of which are made ventilation holes. A valve is installed inside the housing with a actuator for moving it to lock the ventilation holes (see RU 2189426 C2, IPC 7 E 06 B 7/02, publication September 20, 2002).

Known soundproofing device has improved performance by reducing the likelihood of condensation of water vapor on the inner surface of the device.

However, the known device is configured to overlap holes made only in single-leaf windows, and cannot be used in windows consisting of two separate leafs. In addition, the known device reduces the light transmission of windows.

The objective of the invention is to provide a ventilation soundproofing device with enhanced heat and sound insulation and light transmission characteristics, intended for installation in windows with separate shutters.

The problem is solved due to the fact that in the ventilation soundproofing device containing a hollow body with holes and a valve located in it with a drive for moving it, the body has at least one hole on two opposite sides, and the device contains at least , one pair of valves with a common actuator in the form of a differential mechanism, made with the possibility of simultaneous movement of the valves inside the body and in the direction of these holes to seal the ventilation ducts in the frames tvorok.

The valve may have a layer of insulating material.

A seal is installed around the opening on the outside of the cabinet, and the other side of the cabinet is designed to be fixed to the inner casement window.

The differential mechanism includes a support mounted on the housing, a control shaft located in the support groove with the possibility of rotation and movement along the groove, a two-arm lever fixed to the shaft, the ends of which are connected by means of rods and hinges to the corresponding valves.

The differential mechanism used in the proposed device contains rotational and translational pairs and converts the movement of one incoming link to the movement of two output links.

The invention is illustrated by the drawing, which shows a cross section of a noise insulation device integrated in the window unit.

Ventilation soundproofing device is designed primarily for horizontal placement at the top of the window block between the inner casement 8 with double-glazed window 11 and the outer casement 9 with glass 12.

Soundproofing device consists of a hollow body 6, in the opposite walls of which is made at least one hole. These holes are connected to their corresponding holes 10, made in the outer 9 and inner 8 sashes, forming a ventilation channel that provides external air into the room and passes through the sash 9, the housing 6 and the sash 8.

Inside the housing 6 there is a pair of valves 1 with a layer of heat-insulating material, designed to block these holes 10. The movement of the valves 1 is carried out using a differential mechanism, which consists of a control shaft for the position of the valves 2, placed in the groove of the support 4 and made with the possibility of rotation and longitudinal movement along the groove, two shoulders of the lever 3, mounted on the control shaft 2, and a pair of rods 5, each of which is pivotally connected to the lever 3 by one of its ends and connected to the other end and with the corresponding valve 1. The support 4, in a slot which also performs control shaft 2 is placed as a guide valve 1.

On one side of the casing 1, a seal 7 is installed around the outer hole, and the opposite side of the casing is designed to be fixed on the inner casement of the window.

The operation of the ventilation soundproofing device is carried out in two operating modes: the tight closing mode and the ventilation mode.

In the hermetic closing mode, each of the valves 1 is pressed tightly against the shutters 8 and 9 with a layer of heat-insulating material, hermetically blocking the openings 10. The ventilation soundproofing device does not let air from the street into the room.

When the shaft 2 is rotated (counterclockwise in the drawing), the two shoulders of the lever 3 fixed on it rotate, which causes translational movement in the opposite directions of the rods 5 and the associated valves 1, as a result of which the openings 10 open simultaneously. The device starts to work in the mode airing. Outside air enters through the opening of the outer casement 9, passes through the hollow body and then enters the ventilated room through the opening 10 made in the inner casement 8.

The proposed ventilation soundproofing device installed between the outer and inner wings does not reduce the light transmission of the window unit. In addition, it does not require the installation of an additional impost in the window, as it is mounted on existing window elements - sashes.
