DE3717364A1 - Closing mechanism controlled by sound pulses for ventilation vanes - Google Patents

Abstract

TECHNICAL PROBLEM OF THE INVENTION: To eliminate sound emissions (disturbing noises, for example vehicle noise), in that an automatic closing of the ventilation aperture takes place when sound levels which become critical are reached. SOLUTION: When the critical loudness level is reached, a listening microphone transmits the closing pulse to a relay which effects the closing by means of known commercially available mechanisms (fittings). After the noise level falls again, the same mechanism opens the aperture again. POSSIBLE USES: Rooms with a need for natural ventilation which are sensitive to disturbance, are still unprotected from the point of view of construction or can be protected only at a very high cost.

Description

GENUS

The invention relates to a novel Selbsttä termed opening and / or closing controlled by sound impulses operation of windows, ventilation windows or other ventilation openings.

STATE OF THE ART

The soundproofing of windows is based on knowledge of construction physics and development of construction technology to a remarkable Maturity. With soundproof windows of protection classes I-V it is now possible to adapt to almost any interference level. Soundproof windows are already common in residential construction my application. There are also sound insulation fans (e.g. make Siegenia) on the market, both in the window and in the egg can be installed properly next to it, with good success. Finally, the sound insulation of windows is greatly improved effective by using fixed glazing where the sound side paths (rebates and joints) are switched off.

PRIORITY CRITICISM

In practice, the soundproofing of windows unfortunately finds one severe limitation due to the need for ventilation. See one once from buildings with air conditioning systems, which because of the high Construction and operating costs only in comparatively rare cases Find application, so the user has one look no matter how good the soundproof windows are almost always spoiled for choice between Noise and fresh air. During the day, the temporary opening of the Windows for ventilation purposes in residential and office use mostly in The ventilation process is more annoying in conference rooms and bedrooms.

Existing common soundproofing ventilation fittings or So-called "continuous fans" are either not suitable for installation in highly effective soundproof windows, insofar as they have their high sound do not achieve the degree of protection and make it ineffective, or are only applicable for new buildings. The latter also applies to others Systems outside window ventilation too, such as the Arrangement of ventilation ducts in parapets or wall pillars retrofitting involves great costs and disruptions is. So you can rightly assume that in almost all Old buildings and in the majority of all new buildings ("old" and "new" in referenced at the time of knowing the need noise protection in general and the ability to resolve noise protection for windows) a noise-protected ventilation option does not currently exist.  

TASK

The invention aims to close and reopen the movable Automate window and ventilation components, it from the sound Make the level (noise level) of the noise dependent and by Use of standard window fittings, locking mechanisms, Electric motors and switching relays also existing components (old building a wide range of applications with relatively little resources capture (market gap!).

SOLUTION

The object is to be achieved in that the noise, traffic noise in the vast majority of all cases and therefore of increasing and decreasing characteristics when approaching source of interference by means of sound impulses on a listening microphone the outer wall of the building a downstream relay Closing order is issued at the moment when (the Noise) a freely selectable and adjustable on the device Sound level threatens to be exceeded.

The subsequent closing process, which after exceeding this Sound level automatically uses, each by known pre directions, such as

Window scissors,
Worm shoots
Hydraulic pistons
Rope waves or others

take place, the opening process, which falls below the kri table sound intensity automatically, the other way round. However, to simplify the system, a return spring, Cable by weight or by the weight of the opening leaf be closed yourself.

In general, as in special incidents, the selective Selection of a critical interference frequency, even in the already inaudible Frequency range to be considered where this is advantageous appears imprisoned.

ACHIEVABLE BENEFITS

• 1. In contrast to other mechanically operated ventilation devices, the system only ever needs to be switched on when the malfunction occurs. From this result
  • 1.1. lower power consumption
  • 1.2. less wear and tear on wear parts and consequently longer service life with lower maintenance costs
  • 1.3. a lower, due to the time-limited disturbance due to the running noise of the system
• 2. In all cases where the outside noise level is exposed City locations and noise-sensitive objects (office or crane kenhaus) otherwise for the installation of expensive air conditioning or at least Ventilation systems, is now an essential econom more economical alternative available.
• 3. The same applies where the retrofitting of a Buildings with other types of air conditioning or ventilation systems would be relatively expensive.
• 4. The invention also allows a mostly neglected difference Degree of protection of rooms in the same building or component by adding only noise sensitive rooms or space groups (executive offices, conference rooms, bedrooms, sick rooms and others) can be equipped or retrofitted, what is special there appears economical where not all rooms increase the need noise protection.
• 5. By selecting special critical frequencies, the Possibility of adapting to certain prevailing or only significant background noise.
• 6. By lowering the noise level at night or impairment of sufficient oxygen supply the innovation makes a significant contribution to both Public health as well as reducing noise protection costs in the sense of the Emission Protection Act, the public sector concerning.

FURTHER DESIGN

In the sense of the latter advantage (lines 143-145) can the invention after testing and launch anywhere gain special importance where the strong lately principles of sound that have come into public focus protection in urban development currently use relatively high, often as have felt that investment capital is too high and still he request so. B. for sound insulation walls, sound insulation and Similar, often sensitive to the location and landscape intervening measures.

In addition to their advantages of often very effective sound insulation these structures sometimes also accompanying measures of a negative kind in the Ge follow, like impairment of the view and distant view, disruptive view of the system itself u. a.

In typical disturbance situations (residential building on a traffic road) in many cases, the protection against noise was time-differentiated can be tet. One during the night or during the lunch break there is increased sensitivity to noise, it will be different day give times where you, maybe behind the closed (noise protective windows) possibly even the sight of passing Car would like to perceive again.

This creates a very remarkable possibility of interaction passive protection measures on the standardized legal basis the soundproofing was recognizable, u. It may even appear one Reduction, if not general loosening of our currently high, also in the cost impact of high, urban noise protection demands debatable.

Adequate noise control through less complex measures of the "Passive noise protection" thus gains a new perspective.  

EXAMPLE EXAMPLE (see diagram)

A window with a tilt fitting is shown, ie the fulcrum ( 1 ) lies at the base of the window above the windowsill.

Is used for the opening operation and for locking the window sash in the open position (2) an opener scissor (3), as it is commercially available, for example in the upper fold concealed.

An electric motor-operated opener ( 4 ) causes the upper part of the window (optionally the skylight, ventilation flap or similar) to move, triggered by a relay that can either be installed in the opener ( 4 ) or arranged as a separate component ( 5 ).

A eavesdropping microphone ( 6 ) perceives the noise and converts the sound impulses into signal currents which are sent to the relay ( 5 ), which has the property of triggering the closing process in the electric opener at a certain volume that can be set.

Leaves the level of noise when the source of the noise is removed, such as after that, the noise level falls below the critical sound level height, the relay gives the electric opener the impulse to reopen the Window.

If the automatic closing and reopening is also to be carried out in manual mode, it is advisable to install the relay at reach height ( 5 a) , optionally also integration into the high and / or low current line system, for example in the window sill channel ( 7 ).
