Description:
Revolving door

The invention relates to a revolving door com ¬ prising an at least partly cylindrical shell wall, which is embodied with an entrance and an exit, and two rotating door wings, which during normal operation are placed in each other's extended direction inside the shell wall. The ends of the door wings are movable near and along the shell wall.

WO02/10543 discloses such a revolving door, wherein between the shell wall and an end of at least one door wing, a sliding door is provided which is suitable for closing off the entrance or exit respectively, and wherein during normal operation an end of the door wing is constantly positioned near the sliding door and between its lateral edges. In this way the sliding door is able to provide a draught preventing closure between the entrance and the exit, while the door wings pass the entrance and exit to maintain the traffic of persons between entrance and exit of the revolving door.

In order to meet legal requirements it is necessary to implement this known revolving door with an emergency exit provision, which is provided in this known revolving door by the feature that the two door wings can swivel towards each other with the central post or axis of the revolving door as a turning point.

JP 2010 001735 teaches a revolving door comprising an at least partly cylindrical shell wall, which is embodied with an entrance and an exit, and two rotatable door wings, which during normal operation are placed in each other's extended direction inside the shell wall, wherein between the shell wall and an end of at least one door wing, a sliding door is provided which is suitable for closing off the entrance or exit respectively, and wherein the sliding door comprises two adjacent separable sliding door parts. In this teaching each of the door wings is separable into an inner peripheral portion and an outer peripheral portion that may be separated from each other in case an obstruction occurs of the door wing. Furthermore during normal operation the outer peripheral portions of the door wings are connected with a hinge to the sliding doors.

It is an object of the invention to provide a revolving door in accordance with the preamble, with an emergency exit provision which does not require that the two door wings are swivelled towards each other with the central post or axis of the revolving door as a turning point.

To this end, the revolving door according to the invention is characterized in that the end of the at least one door wing is movable closely adjacent to and along the shell wall leaving sufficient room for the sliding door to move between the shell wall and the end of the at least one door wing, and that during normal operation the two adjacent separable sliding door parts of the sliding door are connected to each other, whereas simultaneously during normal operation the end of the door wing is constantly positioned adjacent to the sliding door and between its lateral edges without being connected to the sliding door, and that said two adjacent separable sliding door parts are movable away from each other in an emergency situation to provide a free and unobstructed passage way through the entrance or exit, respectively.

The door of the invention has the advantage of a relatively simple design which is cost-efficient in its manufacture, and that the emergency provision is reliable and operative without the complexities and inertia disad- vantages of the door of WO02/10543. The door of JP 2010 001735 not even provides for an emergency situation.

The advantage of providing users of the revolving door with a quickly and reliably available emergency exit can be further promoted in an embodiment wherein each ro- tatable door wing comprises slidable door wing parts that are slidable to be placed in at least two positions, a first position corresponding to normal operation wherein at least one of the edges of said door wing parts is adja- cent to the sliding door and between its lateral edges, and wherein said door wing parts extend radially away from said sliding door towards a true or imaginary central vertical axis of the revolving door, and a second position corresponding to an emergency situation wherein said door wing parts are at least in part adjacent or next to each other and wherein said edges of said door wing parts are distant from said sliding door to provide a free and unobstructed passage way through the entrance or exit, respec- tively.

The revolving door of the invention of this latter embodiment also makes possible to provide that in an emergency situation, the two adjacent separable sliding door parts are jointly and in a connected condition moved away from the entrance and exit concurrently while the slidable door wing parts are moved from the first position to the second position wherein said door wing parts are at least in part adj cent or next to each other and wherein said edges of said door wing parts are distant from said sliding door to provide a free and unobstructed passage way through the entrance or exit, respectively.

The invention will now be further elucidated with reference to the drawing, which shows:

in figure 1A and figure IB a schematic top view of a first embodiment of the revolving door according to the invention with in figure 1A the door shown in a normal operational situation and in figure IB the door shown when used in an emergency situation;

in figure 2A and figure 2B a schematic top view of a second embodiment of the revolving door according to the invention with in figure 2A the door shown in a normal operational situation and in figure 2B the door shown when used in a first emergency situation; and

in figure 3A and figure 3B a schematic top view of the second embodiment of the revolving door according to the invention with in figure 3A the door shown in a normal operational situation and in figure 3B the door shown when used in a second way that answers to an emergency situation.

Identical parts in the figures carry the same reference numbers.

Referring now first to Figures 1A, 2A and 3A different embodiments of the revolving door 1 of the invention are shown, which are all embodied with an at least partly cylindrical shell wall 2, which is provided with an entrance 3 and an exit 4. Such a revolving door 1 may be provided, for example, in the facade of a building or inside a building for the separation of different rooms that are in communication via the revolving door. Inside the shell wall 2, the revolving door 1 further comprises two rotating door wings 5 and 6, which during normal operation are placed in each other's extended direction. Normal operation as shown in Figures 1A, 2A and 3A entails that the door wings 5 and 6 in said position where the door wings 5 and 6 lie in each other's extended direction, are able to stand still or to rotate about a central column or axis 7. The column or axis 7 may be real or imaginary.

The revolving door 1 is further embodied with a sliding door 10,11 which is provided between the shell wall 2 and an end 8 or 9, respectively, of at least one door wing 5 or 6, respectively. This sliding door 10,11 is dimensioned such that it is suitable to completely close off the entrance 3 or the exit 4, respectively. Preferably the end 8,9 of the door wing 5,6 is constantly near the sliding door 10,11 and between its lateral edges 12,13. In fact the end 8, 9 of the at least one door wing 5, 6 is movable closely adjacent to and along the shell wall 2 leaving sufficient room for the sliding door 10, 11 to move between the shell wall 2 and the end 8, 9 of the at least one door wing 5, 6. A first embodiment of the revolving door of the invention with these features is shown in Figure 1A, a second embodiment is shown in figure 2A, and a third embodiment is shown in figure 3A, wherein said embodiments all have in common that the end 8,9 of the door wing 5,6, as shown in the figures, is normally locat- ed in a permanent position near the sliding door 10,11 and between its lateral edges 12,13 such that the door wings 5,6 and the sliding door 10,11 synchronously move or stand still. It is remarked though that the ends 8,9 of the door wings 5,6 are not connected to the sliding doors 10,11. Anyway, when the door wings 5,6 are rotating, the situation will never arise that a free passage is formed between the entrance 3 and the exit 4 which is accompanied by draught. Draught is therefore effectively prevented.

To accommodate emergency situations in the prior art solution each of the door wings 5, 6 as shown in figure 1A is foldably coupled with the rotatable central column 7, erected centrally inside the shell wall 2. Due to the door wings 5 and 6 being attached to the central column 7 their being folded away causes the ends 8 and 9 of the door wings 5 and 6 to move inward, so that they loose contact with the sliding doors 10 and 11. In the situation where the door wings 5 and 6 are completely folded away, a suitable emergency exit is created providing a roomy pas- sage for large numbers of people that may be on foot or in a wheelchair. Reference is made to WO02/10543 which provides elucidating figures regarding this prior art solution .

The revolving door of the invention has in the manner as shown in figure IB and figure 2B the provision that the sliding door 10,11 comprises two adjacent separable sliding door parts 10', 11' and 10' ',11'' which in normal operation are connected to each other -as is depicted in figure 1A and figure 2A- and that are movable away from each other as shown in figure IB and figure 2B to accommodate an emergency situation in order to provide a free and unobstructed passage way through the entrance 3 or exit 4, respectively.

Figure 1A and figure IB obviously relate to the standard situation that the two wing parts 5, 6 can be fixed into each other's extended direction.

In figure 2A and figure 2B the situation is depicted that each rotatable door wing 5, 6 comprises slida- ble door wing parts 5', 5'' and 6', 6'' that are slidable to be placed in at least two positions, a first position cor ¬ responding to normal operation wherein at least one of the edges 8, 9 of said door wing parts 5', 5'' and 6', 6'' is adjacent to the sliding door 10, 11 and between its lateral edges 12, 13, and wherein said door wing parts 5', 5'' and 6',6" extend radially away from said sliding door 10, 11 towards a true or imaginary central vertical axis 7 of the revolving door, and a second position corresponding to an emergency situation wherein said door wing parts 5' ,5'' and 6 r , 6 ' ' are at least in part adjacent or next to each other and wherein said edges 8, 9 of said door wing parts 5', 5'' and 6', 6'' are distant from said sliding door 10, 11 to provide a free and unobstructed passage way through the entrance 3 or exit 4, respectively.

The embodiment of figure 2A and 2B is also more versatile in that it enables another type of operation to accommodate an emergency situation, which is depicted in figure 3A and 3B . Figure 3A is identical to figure 2A and relates to the normal operation of the sliding door according to this second embodiment. In figure 3B it is shown that it is also possible to accommodate an emergency situation in that the two adjacent separable sliding door parts 10, 11 are jointly and in a connected condition moved away from the entrance 3 and exit 4 concurrently with the slidable door wing parts 5', 5'' and 6' , 6 r ' being moved from the first position to the second position wherein said door wing parts 5', 5'' and 6 ' , 6' ' are at least in part adjacent or next to each other, and wherein said edges 8, 9 of said door wing parts 5', 5'' and 6' , 6' ' are distant from said sliding door 10, 11 to provide a free and unobstructed passage way through the entrance 3 or exit 4, respectively.
