HINGE FOR A DOOR OR WINDOW

Abstract

A hinge for a door or window, including frame and wing parts. The frame part is connected via a joint to a hinge strap extending normally to the rabbet into a receptacle in the wing part to a penetration depth that corresponds to a multiple of the thickness thereof. A clamping part, displaceable in the insertion direction, fixes the hinge strap in position, is pretensioned towards the rabbet by a spring, is arranged under the receptacle and has a guiding section and a clamping section protruding upwards towards the hinge strap into the receptacle. When inserted, the free end of the hinge strap moves the clamping section counter to the spring force. After the hinge strap has been fully inserted and the wing part has been lowered, the clamping part returns to the starting position and the clamping section bears against a lower end face section of the hinge strap.

Way(S) OF IMPLEMENTING THE INVENTION

[0022] FIGS. 1 to 3 illustrate a hinge according to the invention, which has a frame part 1 and a leaf/casement part 2. The frame part 1 comprises a fastening portion 3, which is connected via a joint 4 to a hinge flap 8. The leaf/casement part 2 comprises a housing 7, which, as in the exemplary embodiment shown, can be embodied in multiple parts and can also have different adjusting devices for the fine adjustment of the hinge. Located in the housing 7. on the side that faces the rabbet 5, is a receptacle 6 for the hinge flap 8. Arranged beneath this receptacle 6 is a clamping part 10 consisting of a guide portion 11 and a clamping portion 12, wherein the clamping part 10 is displaceable counter to the force of a spring 9 in the insertion direction of the hinge flap 8. The clamping portion 12 of the clamping part 10 in this case projects upward into the receptacle 6 for the hinge flap 8. Located on that side of the housing 7 of the leaf/casement part 2 that faces the rabbet is, furthermore, an opening 19, through which an actuating portion 18 of the clamping part 10 can be reached by a user. Via the actuating portion 18, the clamping part 10 can be displaced into its release position, when the hinge flap 8 needs to be removed from the leaf/casement part. The hinge flap 8 furthermore has a retaining recess 26, into which, following insertion Into the leaf/casement part, a retaining protrusion 25 in the leaf/casement part engages while the leaf/casement is being lowered. The retaining protrusion 25 can be displaced via an adjusting screw 27 in the insertion direction of the hinge flap 8 in order to adjust the width of the rabbet 5.

[0023] In FIG. 2, the hinge from FIG. 1 is illustrated in a position in which the hinge flap 8 is just being inserted into the receptacle 6 in the leaf/casement part 2. In the process, the free end 13 of the hinge flap 8 presses the clamping portion 12 and thus the entire clamping part 10 backward counter to the force of the spring 9. The hinge flap 8 is inserted until, as a result of the leaf/casement being lowered, the retaining protrusion 25 can engage in the corresponding retaining recess 26 in the hinge flap 8.

[0024] After the leaf/casement part has been lowered, the hinge reaches the position according to FIG. 3, wherein the clamping part 10 returns into its starting position again on account of the force of the spring 9 and the clamping portion 12 now comes to bear against a lower end-face portion 14 of the hinge flap 8. The clearly audible snapping-in of the clamping part 10 signals to the user that the hinge flap 8 has reached its intended end position and is secured within the leaf/casement part 2.

[0025] Finally, as illustrated in FIG. 4, a covering element 20 can also be inserted into the opening 19 in the leaf/casement part 2 and into the lower region of the receptacle 6, with the result that the openings are concealed and also, as a result of the covering element 20. an additional clamping portion 21 for the hinge flap 8 is provided.

[0026] FIG. 5 illustrates one possible embodiment of a clamping part 10. The guide portion 11 has in this case a substantially circular cross section. Provided at the free end of the guide portion 11 is an actuating portion 18. Provided on the underside of the guide portion 11 is a receptacle 17 for mounting the spring 9. Located next to the receptacle 17, at that end of the guide portion 11 that is remote from the rabbet, is a groove 15, in which a housing protrusion 16 (see FIG. 3) is guided. One end of the spring 9 is supported, in the mounted state of the clamping part 10, against the end face of the receptacle 17, while the other end of the spring 9 is supported against the housing protrusion 16.

[0027] FIGS. 6 and 7 illustrate the release position of the clamping part 10 for one possible embodiment of the invention. To release the clamping part 10, the latter, following the removal of the covering element 20 (see FIG. 4), is displaced backward through the opening 19 (see FIG. 3), counter to the force of the spring 9, by pressure on the actuating portion 18. Once the clamping part 10 has been fully displaced, it is pivoted slightly (see FIG. 7), wherein the axis of rotation corresponds to the axis of the circular cross section of the guide portion 11 of the clamping part 10. As a result, the clamping portion 12 is inclined, now bearing against the leaf/casement part 2 at a housing edge 22 and thus securing the clamping part 10 in its release position.

[0028] In FIG. 7, the leaf/casement part 2 is shown from Its rear side, such that the inclined clamping part 10 secured in its release position is readily visible.

[0029] FIGS. 8 and 9 illustrate an alternative embodiment of the clamping part 10. When the hinge flap is released, in this case too, the clamping part 10 is first of all displaced backward by pressing the actuating portion 18 in the leaf/casement part 2 (FIG. 8) and subsequently the clamping part 10 is pivoted slightly upward via the actuating portion 18. As a result, a securing edge 23 on the guide portion 11 of the clamping part 10 comes into engagement with a stop edge 24 in the housing 7 of the leaf/casement part 2, and the clamping part 10 is secured in its release position (FIG. 9).

[0030] Both variants of the damping part can be configured such that, when the hinge flap 8 is reinserted, as a result of the free end 13 of the hinge flap 8 abutting the clamping portion 12 of the clamping part 10, the securing of the release position is undone and the clamping part 10 returns by itself into its starting position as soon as the hinge flap 8 has been inserted fully and the leaf/casement part 2 has been lowered.
