DE102016009648A1 - Device for securing building interiors from water, mud from flood events, heavy rain with unexpected flood events, hail damage, burglary and vandalism - Google Patents

Abstract

In order to secure building interiors from penetrating water and sludge through building openings, a device is proposed which sealingly closes the building opening with an inflatable flat body in the inflated state. The inflatable body is formed by a mat with a gas- and waterproof outer shell and a reinforced foam filling. The building opening is provided with a guide profile for receiving the mat at its outer edges. The mat is in the inflated state in the guide profile movable and is added at least largely watertight closing the building opening in the inflated state at its outer edges in the guide profile by conditioning its outer shell to the inner surfaces of the guide profile.

Description

The invention relates to a device for securing building interiors in front of window and / or door openings penetrating water and mud by flood events, heavy rainfall with unexpected flood events, hail damage and burglary, vandalism, according to the preamble of claim 1.

Large floods of recent times have shown that water and sludge penetrate into rooms through window and roller shutter ventilation and in the interior of buildings can at least partially destroy the inventory or render it useless. So far, attempts have been made to counteract penetration by sandbags, walls or lintels, which was only partially accomplished. In particular, the penetrating mud is particularly destructive. Due to the changed climatic situation, regional, short-term heavy rainfall or hail / heavy hail events occur frequently, which require an additional security option.

A device for securing of building interiors against such events is already out of the DE 102 44 271 A1 known. In this device, the flat opening closing the building opening in the inflated state is formed by a roller shutter curtain consisting of individual horizontal, inflatable segments. The segments are in the inflated state closely nestled against each other and should seal laterally at the soffit of the building opening. In the non-inflated state, the roller shutter curtain is wound in a conventional manner on the roller shutter shaft.

In this device, the individual segments must seal in the inflated state by close contact with each other. The plurality of segments result in a corresponding number of sealing zones, each with the possibility of imperfect sealing.

The present invention, as set out in claim 1, enables a perfected sealing of the building opening by means of a continuous inflatable mat which, when inflated, forms a rigid, flat body. By means of this device windows and / or door openings of buildings can be easily and safely made hermetically sealed. It is a system that can be activated quickly in the event of a disaster and reused as often as desired, and that can be used with refillable, waterproof foam mats as a roller shutter replacement or roller shutter accessory or roller shutter / window attachment. The invention is intended to be used in a complete window system or component or as an additional protection system to be installed or as a retrofit system.

Advantageous developments of the device are specified in the subclaims.

An advantageous embodiment of the invention will now be described in more detail with reference to the accompanying drawings. In the drawings show:

1 a schematic perspective view of the device in the activated state;

2 a schematic perspective view of an inflated mat;

3 a sectional view of the mat;

4 a top view of the mat;

5 a schematic side view of the mat in the inflated (activated) state.

The exemplified embodiment is a roller shutter system which replaces a conventional system and is installed in the soffit of a building opening.

In a largely conventional trained shutter box 10 is a motorized wave 12 rotatably mounted for winding a Rollladenbehangs. As a roller shutter curtain, the system has an inflatable mat 14 which is described in more detail below; in the 1 illustrated state is the mat 14 inflated and completely off the shaft 12 settled.

At the shutter box 10 closes down a guide profile 16 for the roller shutter curtain (the mat 14 ) at. The cross-sectionally U-shaped guide profile 16 is generally of the shape of a rectangular frame, with two vertical segments at the bottom by a ground segment 16a and above by two parallel profile plates 16b and 16c are connected. The leadership profile 16 is thus open from above and allows entry of the mat 14 through the between the profile plates 16b . 16c formed entrance opening, but at the same time of the ground segment 16a closed down.

In addition, the mat is 14 with a circumferential edge strip 14a equipped, which is a foil strip. Here, a higher protection against abrasion should be achieved. Likewise, the inner surfaces of the guide profile 16 covered with a sealing strip.

When inflated, the mat forms 14 a rigid body, with its edge trim 14a close to the inner surfaces of the guide profile 16 is applied. In the non-inflated state, however, the mat can 14 like an ordinary shutter hanging on the shaft 12 wound up and handled by this.

For controlled inflation of the mat 14 is an air pump (in 1 not shown) arranged in the shutter box. This pump is controlled by a sensor that completely reduces the mat 14 reports.

In a preferred embodiment, the roller shutter system is centrally controlled directly or by radio, in particular via an electronic control system that responds to external threats, either by flooding or another type of danger message.

With reference to FIG. 1:

The mat 14 On the one hand, when not inflated, it must be easy on the shaft 12 wound up and can be handled by this, but on the other hand, it must form a rigid, continuous flat body in the inflated state, which is waterproof, does not bend significantly under the load of water pressure and at its outer edge pressure watertight on the profile 16 is applied. A mat meeting these requirements 14 will now be with reference to the 2 to 5 described in more detail.

2 shows a schematic perspective view of an inflated mat 14 in the unrolled state in a frontal view. Dashed lines show the metal rods introduced as a reinforcement in the foam filling 18 , which ensure a regulated winding and unwinding of the mat. Furthermore, these ensure that the mat 14 forms a rigid, continuous, watertight, flat body in the inflated state, which bends only slightly under the load of water pressure and at its outer edge pressure watertight on the profile 16 is applied. At the circumferential edge strip 14a it is a foil strip that protects the mat against abrasion from the guide profile 16 protects.

3 shows the mat 14 in a longitudinal section. You can see hatched drawn the foam body with the spaced introduced, serving for reinforcing metal rods 18 , On the top of the mat are on the one hand the connection 20 for ventilation of the mat and the textile fastener to the roller shutter roller 22 ,

4 shows a plan view of the mat 14 with the connection for ventilation 20 , as well as the textile fastener to the roller shutter roller 22 ,

5 shows a schematic side view of the mat 14 in the activated state. The sensor control ensures that the mat can not be inflated until it reaches the bottom segment of the guide profile 16 abuts and thus has reached the full reduction. By the pressure of the mat 14 put into its maximum expansion state, in conjunction with the two oppositely arranged sealing lips 24 achieved a leak, the ingress of water or mud into the roller shutter box 10 prevented.
