DETAILED DESCRIPTION

(17) The present invention will be described below by means of well-defined embodiments and with reference to certain drawings, but the invention is not limited thereto and is only defined by the claims. The drawings illustrated here are only diagrammatic representations and are non-limiting.

(18) FIG. 1 shows a front view of a simplified representation of a door device 1 according to an embodiment of the present invention. The illustrated door device 1 comprises a door leaf 3 which is pivotably suspended in a door opening 2 by means of a first pivot hinge 4 and a second pivot hinge 4. The first pivot hinge 4 and the second pivot hinge 4 define the hinge pin S about which the door leaf 3 is pivotably suspended.

(19) FIG. 2 shows a cross section through the door device 1 shown in FIG. 1, viewed from the door leaf 3. In this case, the cross section runs through the pivot hinge 4 along the length direction of the pivot hinge 4, as is also indicated by line II in FIG. 1. The pivot hinge 4 comprises a hinge foot 20, at least one insert 30 and screws 40, here also referred to as attachment means 40.

(20) The hinge foot 20 is provided with a first recessed opening 21 and a second recessed opening 21 which extend in a length direction L of the hinge foot 20. The length direction L also determines the orientation of the door leaf 3 connected with the hinge foot 20 in a closed position of the door device 1 with respect to the width direction B of the door opening 2. Each recessed opening 21 is formed by a groove with a width W and an opening situated in the groove.

(21) Each insert 30 (see FIG. 4) is provided with a sleeve 31 with a facetted periphery which has at least one first pair of parallel faces 32′, 32″ and a second pair of parallel faces 33′, 33″. In this case, the distance WAF between the faces in a pair 32′, 32″; 33′, 33″ equals the width W of the recessed opening 21. Furthermore, the sleeve 31 is designed so as to be rotationally symmetrical about a central axis M. Each insert 30 is furthermore provided with a central opening 34. The central opening 34 is eccentric with respect to the central axis M.

(22) The faces 32′, 32″; 33′, 33″ preferably have a width of at least 3 mm, more preferably at least 5 mm, and preferably a height of at least 3 mm, more preferably at least 5 mm. The recessed opening 21 preferably has a depth of at least 3 mm, more preferably at least 5 mm. The height of the faces of the insert is preferably virtually equal to the depth of the recessed opening 21.

(23) The screws 40 attach the hinge foot 20 to the hardening around the door opening 2. The screws 40 extend through the central opening 34 of the insert 30 and through the recessed opening 21 of the hinge foot. A distal part 41 of the screw 40 is situated in the hardening and is preferably provided with screw thread. A proximal part 42, also referred to as screw head 42, is accommodated in the central opening 34 of the insert 30 which is accommodated in the recessed opening 21 of the hinge foot 20. The shape and size of the screw head 42 correspond to the shape and size of the central opening 34. Both are preferably cylindrical, with a height and depth, respectively, of preferably at least 2 mm, more preferably at least 4 mm.

(24) As a result of the reorientation of the insert 30, wherein a different pair of parallel faces bears against the hinge foot, the position of the hinge foot 20 with respect to the screws 40 will change. In this way, the alignment of the hinge foot 20 and the orientation of the hinge foot 20 can be corrected without having to reposition the screws 40.

(25) FIG. 3 shows a cut-away view of a pivot hinge 4 of a door device 1 according to an embodiment of the present invention. The pivot hinge 4 comprises a hinge foot 20 with recessed openings 21, and an insert 30 and a screw 40 for each recessed opening. FIG. 4 shows a top view of the insert 30 of the pivot hinge 40 shown in FIGS. 2-3.

(26) FIG. 5 shows a front view of a simplified representation of the door device shown in FIG. 1 and provided with a magnet assembly 50. FIGS. 6A and 6B show diagrammatic views of magnet assemblies of the door device shown in FIG. 5. FIGS. 7A and 7B show perspective views of parts of the magnet assemblies shown in the preceding FIGS. 6A-6C. FIG. 8 shows a perspective view of a first part 51 of the door device shown in FIG. 5.

(27) For the greatest part, the illustrated magnet assemblies 50 have the same shape and are assembled in the same way. The illustrated magnet assemblies 50 comprise a first part 51 provided on an outer periphery 3′ of the door leaf 3 and a second part 52 provided on an inner periphery 2′ of the door opening 2. The first part 51 is provided with a permanent magnet 53 and the second part 52 is configured to magnetically cooperate therewith, or vice versa. Both parts 51, 52 may be provided with a permanent magnet 53.

(28) The illustrated magnet assemblies 50 differ in the way in which they can be rotated open and/or the way in which they are configured to be attached to an outer periphery 3′ of a door leaf 3.

(29) In the magnet assembly 50 shown in FIG. 6A, the first part 51 is provided on an outer periphery 3′ of the door leaf 3 by means of a screw connection and the second part 52 is provided on an inner periphery 2′ of the door opening 2 by means of a screw connection. The magnet assembly 50 is shown in a closed position of the door device 1, in which the first part 51 and the second part 52 coaxially coincide. As a result thereof, deviations with respect to the optimum alignment can be corrected by correctly positioning the magnet assembly 50. In addition, it is possible with this embodiment to open the door device 1 in two directions.

(30) FIG. 7A shows a perspective view of a part 51; 52 of the magnet assembly 50 shown in FIG. 6A. The part 51; 52 comprises a magnet 53 with an attachment opening, through which screws may extend in order to attach the magnet 53 on the outer periphery 3′ of the door leaf 3 or on the inner periphery 2′ of the door opening 2.

(31) Compared to the magnet assembly 50 shown in FIG. 6A, the magnet assembly 50 shown in FIG. 6B is further provided with stopper means 54. The stopper means 54 prevent the first part 51 and the second part 52 from being able to move over one another and further apart. As a result thereof, the direction of rotation of the door device is limited to a single direction and it is not possible, with this embodiment, to open the door device 1 in two directions.

(32) Compared to the part 51; 52 shown in FIG. 7A, the first part 51 or second 52 shown in FIG. 6B is furthermore provided with a stopper means 54. FIG. 7B shows a perspective view of the stopper means 54 shown in FIG. 6B. The stopper means 54 is formed by a magnet holder 55 for receiving the permanent magnet 53 and a stopper element 56.

(33) The permanent magnet 53 or an element magnetically cooperating therewith is provided in the magnet holder 55. In use, the stopper element 56 extends above the magnet holder 55 in order to prevent another part 51, 52 from being able to move past the permanent magnet 53 into the magnet holder 55. This other part 51, 52 may be an identical part with a stopper means 54 or the part 51; 52 shown in FIG. 7A formed by a permanent magnet 53 or an element magnetically cooperating therewith.

(34) FIG. 8 shows a perspective view of a first part 51 of the magnet assembly 50 shown in FIG. 5. The first part 51 is configured as a magnet holder 55 with spring means and is configured to be provided on an outer periphery 3′ of the door leaf 3 by means of a spring connection. By using a spring connection, it is possible to use the illustrated magnet assembly in combination with a relatively thin door leaf 3, such as for example a glass door leaf. In an embodiment (not shown), the first part 51 may furthermore be provided with stopper elements 56, as shown in the embodiment from FIG. 7B.

(35) In use, the illustrated first part 51 may cooperate with a second part 52 according to FIG. 7A or according to FIG. 7B.

(36) FIG. 9 shows a front view of a simplified representation of the door device shown in FIG. 1 provided with a sealing 60. The sealing 60 is provided between the outer periphery 3′ of the door leaf 3 and the hardening. The sealing 60 comprises a base 61 attached to the outer periphery 3′ and two flexible wing parts 62 which extend from the base 62 along the length direction of the base 61 in a direction at right angles to the outer periphery 3′.

(37) In the closed position of the door device 1, the flexible wing parts 62 seal the space between the outer periphery 3′ of the door leaf 3 and the hardening. To this end, the flexible wing parts 62 are bent when the door device 1 is pivoted into the closed position. These flexible wing parts 62 can gradually seal an opening which varies along the length direction by plastically collapsing upon contact with the hardening.

(38) FIGS. 10A and 11A show cross sections of the sealing 60 shown in FIG. 8. The illustrated sealings 60 differ in the way in which they hinge and/or where on the wing part 62 the hinge point is situated. FIGS. 9 and 10B show these respective sealings 60 with a flexible wing part in a minimal position and a flexible wing part in a rest position.

(39) Two flexible wing parts 62 are provided on either side of the base 62. The wing parts 62 extend inwards. At the free end of each wing part, a projection 63 projecting towards the base is provided. In a rest position of both flexible wing parts, there is an opening 64 between the projections 63 of the two flexible wing parts 62. Upon contact with the hardening of the door opening, a flexible wing part 62 will plastically hinge about a hinge point 65. As a result thereof, the flexible wing 62 will, in the rest position, be deformed in the direction of the base. In the minimal position, the flexible wing 62 will be deformed/collapsed to the greatest extent and will be situated at a minimal distance from the base 61. As a result thereof, the sealing can seal an opening between the door leaf 3 and the hardening over a distance between the minimal distance and the rest position and along the entire length of the sealing 60.
