Hinge for door or window

Abstract

A hinge for a panel or window has a frame subassembly having a frame leaf mountable on a fixed frame and a substantially cylindrical bushing fixed to the leaf and centered on an axis, a panel subassembly having a leaf mountable on the panel of the door and a flange fixed to the leaf, and a hinge-pin assembly pivotally interconnecting the frame and panel subassemblies and having a hinge pin rotatable in the bushing and a part fixed to an end of the hinge pin and having a seat slidably receiving the flange. An adjuster moves the flange in the seat in the hinge-pin subassembly in a transverse direction normal to the axis of the hinge-pin subassembly. A clamping block is slidable in the transverse direction in the part of the hinge-pin assembly. A connecting element secures the clamping block to the hinge-pin subassembly and can slide in the flange.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will now be described in greater detail with reference to an example and with the aid of the accompanying figures. Therein:

(2) FIG. 1 is a schematic perspective view of the essential components of a hinge according to the invention,

(3) FIG. 2 is a partially sectioned view of the hinge of FIG. 1 in the assembled state,

(4) FIG. 3 is a further schematic longitudinal sectional view of a hinge according to the invention,

(5) FIGS. 4 to 6 are each a cross-sectional view of a hinge according to the invention in the different setting positions.

WAY(S) TO CARRY OUT THE INVENTION

(6) FIG. 1 schematically shows the main elements of a hinge according to the invention. A frame subassembly 1 and a panel subassembly 4 are shown one above the other. A hinge-pin subassembly 7 is shown separately next to it for a better view. The frame subassembly 1 comprises a leaf 2 that can be mounted on the frame in a mortise and a bushing 3 held in a corresponding cylindrical part for a hinge pin 8 of the subassembly 7. The panel subassembly 4 likewise has a leaf 5 that can be mounted on the door or window panel in a mortise, as well as a flange 6 that can be inserted in a seat 10 in the upper part 9 of the hinge-pin subassembly 7. In this case, the flange 6 is designed to be thinner by an adjustment distance than the seat 10 in the hinge-pin subassembly 7.

(7) When installed, the flange 6 can be displaced normal to the longitudinal axis of the hinge-pin subassembly 7 by an adjuster 11. Furthermore, T-section clamping blocks 12 are provided that fit with complementary grooves 14. They are aligned parallel to the displacement direction of the adjuster 11. The clamping blocks 12 are connected to the hinge-pin subassembly 7 by connecting elements 13, here in the form of screws.

(8) The longitudinal axes of the screws, the displacement direction of the adjuster 11 and the longitudinal axis of the subassembly 7 are perpendicular to one another.

(9) In FIG. 2, a partially sectional view shows the assembled state. The clamping blocks 12 are held in the seat 10 in the hinge-pin subassembly 7 via the connecting elements 13. The clamping blocks 12 can be moved between a freeing position and a clamping position by loosening or tightening the connecting elements 13. In the clamping position, an end face of the flange 6 comes into surface contact with a face facing it on or in the seat 10 in the hinge-pin subassembly 7. In the view shown, this is one surface each at the top and bottom of the flange that abuts surface at the upper and lower edges adjacent the seat 10. In the freeing position, the position of the hinge can be adjusted via the adjuster 11. After the fasteners 13 have been tightened, the flange 6 is secured without play within the seat 10 and the adjuster 11 is thus relieved with respect to the transmission of forces in the hinge.

(10) In FIG. 3, a further sectional view of a hinge according to the invention is shown schematically. The frame subassembly 1 holds the bushing 3 for the hinge pin 8 for axial adjustment of the hinge-pin subassembly 7. Adjustment is effected by an adjusting screw 15 accessible from below so that vertical spacing between frame subassembly 1 and panel subassembly 4 can be adjusted. To ensure that the adjusting screw 15 is also secured against undesirable rotation, a lower cover cap 16 is provided that can be connected to the bushing 3 via a fixing screw 17. The fixing screw 17 serves as a counter screw to the adjusting screw 15, since it presses the bushing 3 axially against the adjusting screw 15 and secures it in the set position. It would also be possible for the fixing screw 17 to directly counter the adjusting screw 15.

(11) FIGS. 4 to 6 show different settings of the frame subassembly 1 with respect to the panel subassembly 4 in a schematic cross-sectional view. As can be seen, the seat 10 for the flange 6 is wider than the projecting edge of the flange 6 by the possible adjustment distance. In FIG. 4, a position is shown in which the flange 6 is shifted all the way to the left in the seat 10 via the adjuster 11. In FIG. 5, the flange 6 is located exactly in the center within the seat 10, and in FIG. 6, it is located all the way to the right. In addition to the movement by the adjuster 11 that is effected here by a worm screw extending across the seat 10, the clamping blocks 12 located in the freeing position also serve as guides for the hinge flange 6 so that it can be displaced linearly within the seat. The clamping blocks 12 are located above and below the adjuster 11, and the T-shapes of the clamping blocks as well as the T-section grooves 14 run parallel to the direction of adjustment of the adjuster 11.

(12) A cover 18 in the form of a part-cylindrical tubular jacket is slipped over the outside of the hinge-pin subassembly 7 to cover both the adjuster 11 and the connecting elements 13 of the clamping blocks 12. Depending on the position of the flange 6, the cover 18 can be rotated accordingly to allow the passage of the flange 6.
