Definitions

• Self-closing door provided with a self-closing hinge mechanism, and a self-closing hinge mechanism of this type
• the present invention relates to a self-closing door provided with a self-closing hinge mechanism, the hinge axis of which is inclined with respect to the vertical.
• a self-closing door of this type and a self-closing hinge mechanism intended for this door are known from US-A-4,233,708.
• the self-closing door known from this document or more accurately the self-closing gate known from this document, adopts a vertical position in the closed state.
• the axis of rotation of the hinge mechanism used in this case runs along the inside of the rectangular post which supports the gate. In this case, in the closed state the hinge axis intersects the plane which is covered by the gate.
• the gate When the gate is opened, it adopts an inclined position, as a result of which it can close automatically under the influence of the force of gravity when it is released.
• the self-closing hinge mechanism from US-A- 4,233,708 has a number of drawbacks.
• One of the drawbacks is that if the hinge mechanism which is known from this document is used for a gate or door which, in a closed state, has to lie inside a frame, a relatively great lateral clearance is required between the gate/door and the vertical frame part which is remote from the hinge mechanism. This clearance has to be large in particular at the bottom of the gate/door. This is because that longitudinal edge of the gate/door which is remote from the hinge mechanism, when the gate/door is swinging closed, moves not only towards the plane enclosed by the door frame but also towards the vertical jamb to which the hinge mechanism is attached.
• a further drawback of the hinge mechanism which is known from US-A-4,233,708 is that it requires a relatively great frame depth (the dimension perpendicular to the plane enclosed by the frame) or that it is necessary to accept the hinge mechanism projecting forwards out of the frame. This problem will occur in particular in the case of a door, since a door will easily be two to three times as high as a gate.
• a third drawback is that a gate/the door with a hinge mechanism as described in US-A-4,233,708, when the hinge mechanism is completely inside the door frame, can only be opened to an angle of 90°, since in this position the gate/door will come into contact with the inner surface of the vertical jamb.
• the hinge axis of the hinge mechanism described in US- A-4,233,708 can therefore be considered to be composed of a principal vertical component and a single inclination component which is transverse with respect to the plane covered by the closed door.
• German laid-open specification 2,239,419 likewise discloses a hinge mechanism according to the preamble of Claim 1, which hinge mechanism differs from the hinge mechanism from US-A-4,233,708 in that the so-called inclination component is composed of two inclination subcomponents, namely a first inclination sub-component which, as seen when the door is closed, is perpendicular to the plane covered by the door, and a second inclination sub-component which, as seen when the door is closed, runs parallel to the plane covered by the door.
• the hinge described in DE-2,239,419 is obtained by taking two hinges as shown in Fig. 1 and bending them through opposite, different angles.
• the first inclination sub-component is in this case attributable to the oppositely directed bending distances Y, each of different magnitude, and the second inclination sub- component is attributable to the bending distances X, the bending distance X in
• Fig. 7 being different from the bending distance X in Fig. 8, as can also be seen from DE-2,239,419, page 9, last two lines and page 10, top two lines.
• the drawbacks associated with the hinge mechanism described in US-A-4,233,708 also apply to the hinge mechanism described in German laid-open specification 2,239,419.
• the object of the present invention is to provide a self-closing door provided with a self-closing hinge mechanism and to provide a self-closing hinge mechanism, which can be used to overcome the above drawbacks.
• this object is achieved by the fact that, as seen in the closed state of the hinge mechanism, the hinge axis runs substantially parallel to the plane defined by the door and, as seen from the bottom upwards, slopes towards the door. When the door is in the closed position, the hinge axis then has substantially no inclination component in the direction of the plane defined by the door. It thus becomes possible to position the door frame, in particular the vertical jamb thereof which is remote from the hinge mechanism, with little or no clearance, or at least with a clearance which is customary in conventional inside doors, indoor and outdoor doors.
• the final phase of the closing movement of the doors according to the invention namely that of moving into the frame opening, in the door according to the invention takes place virtually identically to with a conventional door.
• a hinge mechanism of this type does not require any additional depth for the door frame.
• the angle ⁇ of the hinge axis with respect to the vertical will be greater than 0°.
• the angle of the hinge axis with respect to the vertical, according to the invention need not be more than 5°, and will preferably be less than 3°.
• An angle of the hinge axis with respect to the vertical of approximately 2° or even smaller has proven to be more than adequate for the self-closing action. It has been found that even an angle of the hinge axis with respect to the vertical of approximately 1° or even less can suffice.
• the door has a front surface, which faces towards the opening direction of the door, if, as seen in the closed state of the hinge mechanism, the hinge axis has an orthogonal projection onto the plane in which the front surface of the door lies, and if the said orthogonal projection touches the front surface at most in its top comer which is on the side of the hinge mechanism.
• the hinge axis In order to ensure that the door is pushed to slightly in the closed position, according to the invention it is advantageous if, as seen in the closed state of the hinge mechanism, the hinge axis, as seen in the opening direction of the door, runs through or along the front of the plane in which the front surface of the door lies. Assuming that the door will be entirely recessed inside the door frame in the closed position, this in practice will mean that the hinge axis runs through or even in front of the plane which is covered by the visible surface of the door frame.
• the hinge mechanism comprises one or more hinge assemblies, in which each hinge assembly comprises a door leaf which is attached to the door and a frame leaf which is or can be attached to a door frame, and in which door leaf and frame leaf are connected to one another in such a manner that they can rotate about the hinge axis, it is advantageous if the door leaf is a leaf which is bent substantially at right angles, the second door-leaf part, which is remote from the hinge axis, being intended to be attached to a longitudinal edge surface of the door and the first door-leaf part of which, which adjoins the hinge axis, is intended to run parallel to the visible surface of the door frame when the door is in the closed position.
• the hinge mechanism comprises one or more hinge assemblies, in which each hinge assembly comprises a door leaf which is attached to the door and a frame leaf which is or can be attached to the door frame, and in which door leaf and frame leaf are connected to one another in such a manner that they can rotate about the hinge axis
• the frame leaf has a first frame-leaf part, which adjoins the hinge axis and is provided, at a distance from the hinge axis, with a second frame-leaf part which is substantially at right angles to the said first frame-leaf part, the frame-leaf part preferably being a leaf which is bent substantially at right angles.
• the second frame-leaf part will bear as a stop against the inner surface of the door frame which is at right angles to the visible surface of the door frame.
• the invention also relates to a self-closing hinge mechanism which is intended for a self-closing door according to the invention.
• the invention relates in particular to a self-closing hinge mechanism for a door which is to be hung in a door frame and of the type in which the hinge axis is inclined with respect to the vertical, comprising one or more hinge assemblies each having a door leaf, which it to be attached to the door, and a frame leaf, which is to be attached to the door frame, the door leaf and the frame leaf being connected or connectable to one another in such a manner that they can rotate about the hinge axis, characterized in that the frame leaf is provided with a first frame-leaf part, which is intended to be positioned against, or at least along, the visible surface of the frame and adjoins the hinge axis, and in that the door leaf is provided with a first door-leaf part, which adjoins the hinge axis, in that in the closed state of the hinge assembly the first door-leaf part runs parallel to the first frame-leaf part and covers this first frame-leaf part on the side thereof which is remote from the frame.
• the frame leaf has a second jamb-leaf part which is bent at right angles along a fold line and is intended to be positioned against or at least along that section of the door frame which lies inside the door passage.
• the door leaf is provided with a second door-leaf part which is bent at right angles and is intended to be attached to a longitudinal edge surface of the door.
• Fig. 1 shows a diagrammatic front view of a self-closing door according to the invention, in the closed position
• Fig. 2 shows a front view of the door shown in Fig. 1, but now in the open position
• FIG. 3 shows a perspective view of a top hinge according to the invention, specifically the top hinge for the door shown in Fig. 1 and 2;
• Fig. 4 shows a perspective view of a bottom hinge according to the invention, specifically the bottom hinge of the door shown in Figures 1 and 2; and
• Fig. 5 shows an enlarged view of detail N from Fig. 1.
• the figures show a door 1 with a front surface 31 which faces towards the opening direction and a door frame 2 with a vertical jamb 3 which bears the top hinge 4 and a bottom hinge 5.
• the hinges 4 and 5 have a common axis of rotation 7 which is at an angle ⁇ with respect to the vertical. This angle ⁇ is approximately 1 °.
• the hinge axis 7 runs parallel to the plane which is covered by the door and, when referring to Fig. 1 , runs parallel to the plane of the drawing. Referring to Figure 1 and 2, the hinge axis 7 therefore runs parallel to the plane of the drawing, at an angle ⁇ with respect to the vertical.
• Figures 3 and 4 show a perspective view of the top hinge and the bottom hinge according to the invention, in the partially open state.
• 8 denotes the visible surface of the vertical jamb 3
• 9 denotes the surface which faces into the door opening, at right angles to the visible surface.
• the bearing surface against which the back panel of the door comes to bear when the door is closed and which is substantially at right angles to the inner surface 9 of the frame is denoted by 33.
• the detail N from Fig. 1 which is shown in Fig.
• the hinge axis 7 touches the inside comer of the outer surface of the door frame. It should be noted that if appropriate it is possible for the hinge axis 7, or at least the orthogonal projection thereof onto the plane in which the front surface 31 lies, touches the comer 32 of the front surface 31.
• Positioning the hinge axis 7 in such a way that at least its orthogonal projection onto a plane in which the front surface 31 of the door lies does not intersect this front surface (in which case the said orthogonal projection would have two intersections with the peripheral contour of the front surface 31) ensures that the final phase of closing the door, namely the door moving into the frame, is virtually identical, down to the smallest detail, to a conventional door moving into the frame.
• this embodiment not only is it possible to use conventional frames (i.e. frames of conventional dimensions), but also it is not necessary to adapt the shape of the conventional frame locally.
• a hinge mechanism according to the invention with a hinge axis 7 whose orthogonal projection onto the plane in which the front surface of the door will lie in the closed position at most touches the outer contour of the front surface 31 and does not intersect this outer contour is for this reason eminently suitable for the so-called replacement market.
• the top hinge 4 comprises a frame leaf 11, 13, also referred to as jamb leaf 11, 13, which is attached or at least intended to be attached to the vertical jamb 3.
• the top hinge also comprises a door leaf 14, 16 which is rotatably attached to the frame leaf 11, 13 along the hinge axis 7 and, moreover, is intended to be attached to the door 1.
• the frame leaf comprises a first frame-leaf part 13 which adjoins the hinge axis 7 and in the fitted state runs parallel to the visible surface 8 of the vertical jamb 3, preferably will bear against this surface, and a second frame-leaf part 11, which in the fitted state will bear against the inner surface 9 of the vertical jamb 3.
• the first frame-leaf part 13 and second frame-leaf part 11 are connected to one another via a right-angled fold 12.

In the closed position of the door, the second door-leaf part 16 will bear against the second frame-leaf part 11.
• the first door-leaf part 14 is intended to lie along or against the frame-leaf part 13 in the closed position of the door.
• the bottom hinge 5 comprises a frame leaf 21, 23, also referred to as the jamb leaf 21 , 23, which is attached or at least intended to be attached to the vertical jamb 3.
• the bottom hinge 5 also comprises a door leaf 24, 26 which is rotatably attached to the frame leaf 21, 23 along the hinge axis 7 and moreover is intended to be attached to the door 1.
• the frame leaf comprises a first frame-leaf part 23, which adjoins the hinge axis 7 and in the fitted position runs parallel to the visible surface 8 of the vertical jamb 3, preferably will bear against this surface, and a second frame-leaf part 21, which in the fitted position will bear against the inner surface 9 of the vertical jamb 3.
