Door hinge or window hinge

Abstract

A door hinge (1) or window hinge (1) having two hinge parts (2,4) which are operatively connected to one another so as to be rotatable about a common hinge axis (2), wherein at least one door-or-window-side first hinge part (3) has a plate-like portion (8) which interacts in a fixedly and releasably connectable manner with a holding piece (9) which can be inserted into a groove in the end side of the door or window, wherein the plate-like portion (8) is oriented in an imaginary plane running parallel to the hinge axis (2) and is adjustable with respect to the holding piece (9) in an imaginary plane running at a right angle to the plane of the plate-like portion (8), and wherein an adjustment screw (11) can be screwed into at least one thread (1) of the holding piece (9). Provision is made for a head (12) of the adjustment screw (11) to be arranged between an intermediate piece (14) and the plate-like portion (8) by a clamping device (5) which applies to force to the plate-like portion (8) and the intermediate piece from opposite side and thus hold them together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) In the following description of the drawings, the same reference numerals designate identical or comparable components.

(10) FIG. 1 shows a perspective view of a hinge 1 according to the invention. FIG. 2 shows a plan view, perpendicular to the hinge axis 2, of the first hinge part 3 of a hinge 1 according to the invention. FIG. 3 shows a partially cut side view of a hinge 1 according to the invention. FIG. 4 shows a partial perspective view of the first hinge part 3. The door or window hinge 1 shown comprises a first hinge part 3 and a second hinge part 4. The first hinge part 3 and the second hinge part 4 are connected together via a connection plate 23. The second hinge part 4, which is normally mounted on a door or window frame using the mounting pins 24, has two lateral bearings 25, 26 and a central bearing 27. The bearings 25, 26, 27 are arranged on an adjusting pin 22, the longitudinal extension of which defines the hinge axis 2. The central bearing 27 is rigidly connected to the adjustment bolt 22 via a grub screw 28, while the adjustment bolt 22 can rotate relative to the lateral bearings 25, 26 when the door or the window is pivoted.

(11) The first hinge part 3 comprises a retaining piece 9 with which it can be inserted into a groove of a door or a window. Furthermore, the first hinge part 3 comprises a plate-like portion 8, an intermediate piece 14 and a plurality of mounting and adjusting elements. The structure of the first hinge part 3 can be easily identified on the basis of FIG. 3. The plate-like portion 8 and the intermediate piece 14 are held together by means of clamping bolt 13, onto which a sleeve 18 is mounted. The clamping bolt 13 and the sleeve 18 together form a clampinig device 5. The intermediate piece and the plate-like 14 portion 8 are designed so as to hold a head 12 of an adjustment screw 11, wherein this head 12 is received by the intermediate piece 14 and the plate-like portion 8 with as little play as possible, or with no play at all. The plate-like portion 8 has longitudinal hole-like adjustment holes 20, through which the head 12 of the adjustment bolt 11 is accessible using a tool, in this example using an Allen key. The arrangement of plate-like portion 8, intermediate piece 14 and adjusting screws 11, held together thus by the clamping bolt 13 and sleeves 18, is connected to the retaining piece 9 by the fact that the adjusting screw 11 is screwed into a thread 10 of the retaining piece 9. This attachment of the arrangement consisting of the plate-like portion 8, intermediate piece 14 and adjusting screws 11 with the retaining piece 9 is not impeded by the clamping bolt 13 or the sleeves 18 placed thereon, because the sleeves 18 are displaceable in drilled holes 19 of the retaining piece 9 provided for this purpose and thereby provide an additional guide. The whole arrangement described is then also secured by means of a fixing screw 6. The fixing screw 6 rests with its screw head on the plate-like portion, it passes through openings in the plate-like portion 8 and the intermediate piece 14, wherein the hole in the plate-like portion 8 is designed as a longitudinal slot 7 and it is screwed into a thread of the retaining piece 9. Since in the plan view of FIG. 2 the longitudinal slot 7 is hidden by the screw head of the fixing screw 6, this is shown here by a broken line.

(12) The clamping device 5, which comprises a bolt-type shaft 17 and an sleeve 18 connected to it, has as a further special feature, on the end facing away from the sleeve 18, an eccentric 16. The entire clamping device 5 with eccentric 16 in this example therefore comprises two cylindrical sections, i.e. the bolt-like shaft 17 and the eccentric 16, whose axes run parallel and are offset with respect to each other, and also the sleeve 18 which is arranged on the side of the clamping device facing away from the eccentric. The eccentric 16 rests with a collar on the plate-like portion, and it is guided by means of a longitudinal slot 29 in the plate-like portion. The bolt-like shaft 17 adjoining the latter passes through an opening in the intermediate piece 14. The collar of the eccentric 16 and the sleeve 18 of the clamping device 5 generate the opposing force components which hold the plate-like portion 8 and the intermediate piece 14 together.

(13) An adjustment of the hinge perpendicular to the plane of the plate-like portion 8 and perpendicular to the hinge axis 2 is effected in accordance with the above described assembly of the first hinge part 3. A tool is passed through the adjustment opening 20 into the head 12 of the adjustment screw 11. By the adjusting screws 11 being screwed into the thread 10 of the retaining piece to a greater or lesser extent, the desired position of the hinge is obtained. The sleeves 18 slide in the holes 19 provided in the retaining piece 9 as guides.

(14) If an adjustment of the hinge parallel to the plane of the plate-like portion 8 and perpendicular to the hinge axis 2 is to be made, then the eccentrics 16 are used. The eccentrics 16 in FIG. 2 and FIG. 3 are in their central position. If by means of a rotary device 15 of the eccentric 16 the latter is turned in the + or direction, the plate-like portion 8 moves relative to the intermediate piece and the retaining piece 9, allowing an adjustment of the hinge in the above-mentioned direction to be performed. Before this adjustment operation the fixing screw 6 is preferably released, thereby reducing the friction between the plate-like portion 8 and the intermediate piece 14. After the adjustment operation the fixing screw 6 can be re-tightened.

(15) FIG. 5 shows a partially cut side view of a hinge 1 according to the invention. FIG. 6 shows a partially cut top plan in the direction of the hinge axis 2 of a hinge 1 according to the invention. The second hinge part 4 comprises a adjusting bolt 22 already mentioned, which acts as the axis for the two lateral bearings 25, 26 and a central bearing 27 and defines the hinge axis 2. The adjusting bolt 22 is connected to the central bearing 27 via a grub screw 28 (see FIG. 1). For this purpose the adjusting bolt 22 comprises a constriction 30. The central bearing 27, which is connected via the connection plate 23 to the first hinge part 3 and turns together with the door, is fitted with sockets 31, 32, 33, 34, which can be displaced relative to steel rings 35, 36 of the lateral bearing 25, 26. The steel rings 35, 36 of the lateral bearings 25, 26 are displaceable relative to the lateral bearings 25, 26. In order to prevent the steel rings 35, 36 from turning in the lateral bearings 25, 26, these rings are not designed completely round, rather they have one or more flattened regions 37.

(16) Since the adjusting bolt 22 is thus axially displaceable relatively to the lateral bearings 25, 26, this can be fixed in its axial position. This is effected via an axially acting screw 38, preferably a grub screw, which is screwed into the end of the lateral bearing 26 and via which the hinge can be adjusted in the direction of the hinge axis 2. It is possible to unscrew the axially acting screw 38 out of the lateral bearing 26 completely, to arrange the adjustment bolt 22 the other way around than shown in FIG. 5 and then to screw the grub screw 38 into the other lateral bearing 25. In this way it is possible to produce a left-hand hinge from a right-hand hinge and vice versa.

(17) The features of the invention disclosed in the description, the claims and the drawings can be essential to the implementation of the invention both individually and in any desired combination.
