DE10301045A1 - External shutters for window have a thermally insulating construction and are operated by remote control via integral motors powered by solar cell changed batteries - Google Patents

Abstract

The invention comprises external shutters (1) for windows with a thermally insulating construction. The shutters are driven by electric motors powered from batteries (7) charged by solar cells (8) on the shutters. The operation of the shutters is by remote control and/or by light level monitors (9) on the top edge of the shutters. The electric motors operate on the shutter hinges via a hexagonal drive.

Description

The invention relates to a shutter the preamble of claim 1.

Such a shutter is on the outer wall attached to a house and is used to open a window Outside to close. Such shutters often exist made of wood, being common are designed as a lamella construction. Generally offer they only provide protection against incidence of light when closed, do not contribute or only very little to the thermal insulation. Furthermore, in Generally to close a conventional one The window open, so that the user can unlock the shutter and swing it into the window opening. This means that indoor air is exchanged, especially in winter the cold outside air instead, causing a lot of warmth get lost.

The object of the invention is therefore the thermal insulation properties to improve a shutter and design it in such a way that heat loss when used is largely avoided.

This task is solved with a shutter that has the features specified in claim 1.

According to the invention, the shutter consists of a highly heat-insulating Material, so that when closed, the heat flow from the window to the outside largely blocked. It has a motor drive, so it by means of a remote control or a brightness control installed in it can be closed without opening the window got to.

In the shutter is still that Energy supply, for example a battery, added for the motor drive, so that no connection cable to the power grid of the house is required is. The motor control has a limit switch for the opening and the closed position of the store. This limit switch is preferably switched off in such a way that the movement of the store depending on the load is stopped when the movement is interrupted by an obstacle.

It preferably has one Shop on the in the open State to the outside facing surface a solar cell module with which the one serving as energy supply Battery is being charged.

The invention is described below of the embodiment shown in the figures and closer explained.

Show it:

1 a window with two shutters according to the invention in the open state;

2 the shutters in the closed state;

3 a schematic representation of the integrated units in the shutter.

1 shows a window 2 with two shutters open, on hinges 3a . 3b are pivoted to the right and left of the window opening. Each shutter consists of a blackboard 1 made of heat-insulating material, e.g. polyurethane foam. It is with a lower and an upper hinge 3a . 3b pivotally attached to the window frame. The surfaces of the board 1 can be coated with a layer of impact and scratch resistant plastic. The narrow sides of the panels are covered by a metal sheet 4 protected. An electric motor serves as the drive unit. It is attached to the window frame and acts on the part of the lower hinge attached to the shutter via a hexagon connection 3a , Alternatively, the engine 5 also on the board 1 be attached and to the part of the hinge attached to the window frame 3a Act. Inside the board 1 are a control 6 and an accumulator 7 arranged for energy supply. There are two solar cell modules on the side of the shutter that points outwards when open 8th attached to the accumulator 7 charge. A brightness sensor 9 is arranged, for example, in the wall of the house and via a flexible cable with the control located in the permanent store 6 connected. The brightness sensor is preferably 9 ' however attached to the upper edge of the shutter. A separate brightness sensor is provided for each shutter.

The electric motors 5 the shutters are each provided with a limit switch for the completely open and the completely closed state in order to avoid damage. This limit switch can be implemented, for example, by a counter that records the revolutions of the motor 5 counts in one and in the other direction. With a 3-channel remote control, not shown in the figures, the shutters can be opened, closed or moved under brightness control. The motor 5 is equipped with a sensor for measuring the load torque, so that when the shutter is blocked by an obstacle, the motor is stopped.

2 shows the window with shutters closed.

Corresponding 3 the current that the solar module supplies to the accumulator is controlled by a charge controller. The control unit reacts to signals from the brightness sensor and the radio reception module and emits a corresponding signal to the drive motor, which is also supplied by the accumulator.
