DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an entrance device according to the preamble of claim 1.
2. Description of the Prior Art
Such an entrance device is known from European patent application 0 296 134. This document discloses the application of a revolving door having at its output and input sections sliding doors designed to move in cooperation with the movement of the revolving door. The movement or position of the revolving door and the respective sliding doors can also be switched to independent operation whereby the revolving door is put in a stationary position in parallel with the passage through the revolving door assembly. The sliding doors may or may not move to and fro in their path in order to either provide a full and restricted passage or to provide a pure sliding door operation. In normal use, the entrance device of EP 0 296 134 requires a rather complicated cooperation of said sliding doors and the revolving door assembly.
SUMMARY OF THE INVENTION
It is the object of the invention to provide an entrance device according to the preamble of claim 1, having simpler operation and allowing for automatic switch over from one type of operation to the other depending on environmental conditions. In this way, high energy saving and optimal draft exclusion can be obtained in a first way of operation, whereas large capacity can be provided in a second type of operation.
The objectives of the invention can be obtained with the entrance device according to the preamble of claim 1, which is characterized in that the entrance device comprises two revolving doors and that the sliding door is arranged in the pathway between said two revolving doors.
In a certain aspect of the invention, the entrance device has a programmable control system including sensors for measuring environmental parameters, such as temperature, air humidity, wind speed or the like, to determine, on the basis thereof, the most convenient way of using the entrance means.
It is acknowledged that EP 0 296 134 discloses the use of a detector or similar sensing means to initiate a starting pulse for the drive motors that are used to operate the revolving door assembly and the sliding doors as disclosed in said publication. Such detector is, however, merely used to detect a person that is approaching the entrance device. It does not provide any means to identify the most convenient way of using the entrance means based on environmental conditions, such as temperature, air humidity and other weather conditions.
In a favourable embodiment of the entrance device according to the invention it also comprises an air treatment device and/or an air curtain. Such apparatus are known in the art but support the objective of the invention to provide energy saving and yet a high capacity entrance device depending on circumstances at hand.
According to the invention the entrance device can be adapted to environmental circumstances providing optimal comfort, a low energy use and a desired capacity, throughout the year. Preferably, the control system automatically switches to the most convenient manner of operation of the entrance device based on the measurements of the said environmental conditions. As an alternative the control system may be switched to semi-automatic operation whereby advice is given on the basis of the parameters measured by the sensors with regard to the most convenient operation under the measured circumstances.
