Device for providing access to a space

摘要

The present invention relates to a device for providing access to a space, wherein the space is provided with an access element, such as for instance a door or window, wherein the device is provided with pressing elements for exerting an impact force on one or more parts of the access element, such as for instance a door frame, comprising:
an elongate housing,an elongate impact element for exerting the impact force on the access element which is adjustably movable between a starting position and an end position by a first drive,the first drive adapted to produce the impact force,the impact element is comprised in a first guide extending along the impact element,the impact element is provided from close to the first outer end up to at least an exit opening with a narrowed portion,the first drive comprises a first fluid reservoir provided with a first fluid suitable for high-pressure application, wherein in the starting position of the impact element the first fluid is arranged compressed in the first fluid reservoir and the first fluid reservoir is in fluid communication with a first side of the first outer end of the impact element,and activating elements for activating the device.
