ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a device for operating linked and guided closure installations such as windows, doors, flaps, screens or sliding panels.
2. Description of the Related Art
Closure devices already exist, operating by means of a sliding arm, one end of which is connected to the door by a swiveling link, while the other end is free to slide vertically in a guide rail on the door frame. Such door closure devices close the door when the force used to open it is withdrawn, for example, if the person opening the door releases it. This occurs immediately. No delay is envisaged between the withdrawal of the force and the closure of the door. The closure device consists of several parts, and is of a complicated construction.
Devices powered by an electric motor are also used for closing doors and windows. Time switches installed in the current/voltage circuit of the electric motor can be used to set the time at which the window or door should be opened or closed. One disadvantage of such closure devices is that they are expensive to buy, and also that they require a considerable amount of electricity, and thus have a high energy consumption.
SUMMARY OF THE INVENTION
The present invention provides a device which overcomes these drawbacks. Specifically, a device according to the present invention has the advantage that the closure device is connected by way of a traction mechanism to the frame of the closure device set in the wall, and that the traction mechanism can be coiled around a shaft, which operates on the closure device by means of a spring. An adjusting device on the shaft is used to adjust the force exerted by the spring on the traction mechanism. When the closed position has been reached, the closure device is locked onto the frame by means of a bar. Utilizing the force exerted, and the proportional relationship, it is possible to adjust the acceleration of the closing device during closing that is produced by the traction mechanism. The smaller the force, the less the acceleration, thus producing, the speed of closure accordingly. Consequently, the force of the spring, transmitted to the closing device by the traction mechanism, can be used to adjust the speed of closure.
One advantage of the device is its relatively simple construction, consisting of only a few parts. This means that its manufacture and installation are simple and inexpensive to perform. The device is of a purely mechanical construction, requiring no electrical power whatsoever. The closure device has many applications. For example, it can be installed on various types of closure installations such as windows, doors, flaps, screens or sliding panels. The closure device is also simple to operate.
A further advantage of the invention is realized when the closure installation consists of a swiveling window, turning on a horizontal axis in one position, for example, a window in a toilet, bathroom, living room, bedroom or office, or a swiveling skylight. When the window is opened, this causes the spring attached to the shaft to be released. The ensuing force of the spring ensures that the window automatically closes again, within the time selected on the adjustment device. This eliminates the risk of a previously opened window remaining inadvertently open over a longer period, which could allow access to burglars, or, during bad weather, penetration by cold air, rain or snow. In the case of heated rooms in particular, a window left inadvertently open for an extended period of time allows cold air to flow in, causing the heating system controlled by a thermostat inside the room to turn up the heat. The advantage of the closing device represented by this invention is that the window is automatically closed after a predetermined time, thus minimizing the amount of energy consumed by the heating system. This in turn reduces heating costs and helps to protect the environment.
A further advantage of the invention is that the traction mechanism preferably consists of a pull rope.
Other advantages and advantageous design features of the invention can be seen from the following description, the drawing, and the claims.
