Definitions

• the invention relates to a space-saving or disabled door according to the preamble of claim l.
• a door according to the preamble of claim 1 is already known.
• the door resulting from this publication has a door leaf which is articulated on a lower and upper horizontal arm.
• the brackets are mounted on a rotary guide arranged on the side of the door leaf and can be pivoted about a vertical swivel axis.
• a guide member in the form of a pivot pin is provided in the upper area of the door leaf, which is guided laterally but not vertically on a horizontal guide rail.
• the kinematics of the door which is predetermined by the extension arm, the rotary guide and the guide rail, is such that the door leaf is not pivoted about a lateral pivot axis as in a conventional door, but rather moves through the combination of a pivoting and translatory movement around the operator. Therefore, the door can be operated by a person with reduced mobility or a wheelchair user without difficulty.
• the rotary guide additionally required for this type of door for the boom has a gallows which is articulated on one side of the door frame.
• a special frame required to hold the gallows can be placed on an existing door frame of a door leaf to be replaced. The exact attachment of the gallows to the door frame or the additional special frame can not be found in detail in this document.
• Doors of a similar design which differ from CH-PS-593 411 only in their lock mechanism, are known from DE 41 12 851 C2 and EP 0 446 558 A2.
• Standardized steel frames for interior doors are known from the German standard DIN 18101.
• the invention is therefore based on the object of specifying a space-saving or handicapped-accessible door according to the preamble of claim 1, in which an assembly on conventional standard door frames and thus a conversion of a conventional door to a handicapped-friendly special door is possible without changing the door frame.
• the object is achieved by the characterizing features of claim 1 in conjunction with the generic features.
• the invention is based on the knowledge that the mounting slots provided on standard door frames for receiving the hinges of conventional doors can also be used for fastening the rotary guide of the door according to the invention.
• the rotary guide has a fixed fastening element, on which projections are provided which extend substantially perpendicular to the pivot axis and which can be inserted into the mounting slots provided on the door frame and clamped to the door frame.
• the brackets are connected to this fastener via a swivel bearing.
• the assembly effort is then very low: only the protrusions already prefabricated on the fastening element are to be inserted into the corresponding mounting slots of the door frame and clamped to the door frame. This takes place in a manner similar to how the hinges of the door are inserted into these mounting slots in a conventional door and are jammed there.
• the elements of the door according to the invention in particular the door leaf, the extension arm and the fastening element, can be preassembled. It is only necessary to attach the guide rail to the door frame and, if necessary, to mount a stop profile strip on the side of the door frame opposite the fastening element.
• the conversion of a conventional door to the space-saving or disabled-friendly door according to the invention in particular does not require the removal of existing door frames and, if appropriate, the insertion or fitting of a special frame.
• the fastening element can be designed as a one-piece tube according to claim 2. It is always in the End area of the one-piece tube, a flat projection is provided, which can be inserted into an upper or a lower mounting slot of the door frame.
• the one-piece, tubular design of the fastening element has the advantage of a special stiffening of the rotary guide.
• the fastening element can also consist in two parts of an upper tube section for receiving the upper pivot bearing for the upper boom and a lower tube section for receiving the lower pivot bearing for the lower boom. Each tube section then has a flat projection, which can be inserted into an associated mounting slot of the door frame. Material is saved because the two pipe sections are not connected to one another.
• both the upper and the lower arm have a door leaf section which lies in the closed plane of the door leaf and fills a recess in the door leaf, the length of which is substantially the same as the length of the door leaf Door leaf section matches.
• the booms are arranged in the closed state of the door in front of the level of the door panel and the door panel is raised to such an extent that a gap remains between the door panel and the floor which causes the lower boom to swing through allowed
• the boom is largely integrated into the door leaf and hides a corresponding recess in the door leaf.
• the door leaf extends outside of this recess to the floor. There is no gap between the door leaf and the floor.
• the fact that the arms are integrated into the door leaf when the door is closed and do not protrude from the door leaf results in a more pleasing appearance. Furthermore, a risk of an accident is counteracted.
• Each bracket for connection to the fastening element can have an angled mounting section and a connection for connection to the door leaf, the mounting section for connection to the fastening element and the projection for connection to the door leaf lying diagonally opposite on the door leaf - Section of each boom are molded.
• the boom is prevented from swinging into the door leaf at the edge of the recess when the door is opened, as would be the case if the axes were arranged on the same side of the door leaf.
• the door leaf can extend down to the floor outside the extension arm and up to the guide rail.
• the mounting section of the boom can claim accordingly
• the guide rail preferably has one or more running surfaces for vertical support of the door leaf.
• this has the advantage that the weight support of the door leaf is at least partially carried out via the guide rail and thus the arms of the rotary guide can be designed to be weaker.
• the guide member provided on the door leaf according to claim 9 has a carriage with at least one impeller on the Rolls running surface of the guide rail and thus enables smooth operation.
