EP1948893B1 - Lifting device for a two-wing folding flap - Google Patents

Abstract

The lift device comprises a double-armed lever (34) and a hinge arm (31) connecting the two flap parts (12,14). The hinge arm is mounted in hinge sockets (28,29) mounted in the flaps. The hinge arm is designed to move relative to a hinge socket about a first eccentric in one direction and about a second eccentric in the other direction which is perpendicular to the first direction. The hinge arm is held with play by a pin on an intermediate plate so that it can be displaced through the first eccentric which is mounted rotatable in the intermediate plate.

Description

The invention relates to a lifting device for a two-leaf folding flap according to the preamble of claim 1.

From the DE 201 00 662 U is a lifting device for a two-winged jaw known whose upper wing is hinged about a horizontal first axis on a cover or partition of a cabinet and the lower wing is pivotally connected about a second axis parallel to the first axis pivotally connected to the upper wing. The lifting device consists of at least one two-armed lever, which is pivotally mounted about a horizontal pivot axis on a side body part and whose longer arm is pivotally connected to the lower wing. Furthermore, a compression spring element is present, one end of which is pivotally connected to the body part and the other end pivotally connected to the shorter lever arm.

The known folding flap is opened by a person grasping a handle, not shown but required, connected to the lower wing, which must have a certain distance from the lower edge of the lower wing.

There is a need to provide lifting devices of the aforementioned type, which allows the opening of the folding flap by simply pulling the lower edge of the lower wing, without the need for a handle must be provided.

Such a lever device for a two-leaf folding flap is from the German utility model DE 20 2005 016 405 according to the features mentioned in the preamble of claim 1 known. Here, a lifting device for a double-leaf folding flap is described, which has a hinge provided with a hinged pot which can be used on one of the wings and a hinge arm which can be fixed on the other wing for connecting the two wings. In one of the embodiments shown in this utility model of the hinge arm is connected in both wings with pins in the respective existing in the wings hinge cups, so that the two leaves are pivotally connected to each other in a very squat and space-saving form. In another embodiment, the hinge arm is connected on the one hand in a hinge cup with one of the wings and on the other hand in the form of a conventional Viergelenkschamiers with the other wing. Due to the use of the usual four-bar hinge an adjustability in the three coordinate directions is possible here, so that the wings are adjustable by appropriate adjustment in the three spatial coordinates against each other and the furniture body. Such adjustability in the various coordinate directions is not possible in the embodiment in which the hinge arm is mounted with each end in a hinge cup.

Object of the present invention is therefore to develop a lifting device according to the preamble of claim 1 to the effect that hinges, which are mounted with each end in a hinge cup, can be provided with adjustment means in two coordinate directions, on the one hand the lateral alignment of the wings and the Allow adjustment of the distance from each other.

This object is achieved by the combination of the features of claim 1. Accordingly, the hinge arm is adjustable relative to one of the hinge cups via a first eccentric in one direction and via a second eccentric in another direction perpendicular to the first direction.

Particular embodiments of the invention will become apparent from the subsequent claims to the main claim.

Accordingly, the hinge arm can be supported on at least one pin on an intermediate plate with play so that it is adjustable over the rotatably received in the intermediate plate first eccentric. Between the hinge arm and the hinge cup to which it is attached, an intermediate plate is present, which is guided displaceably on the hinge cup perpendicular to the hinge axis and on which the hinge arm is displaceable parallel to the pivot axis, wherein the corresponding relative positions by the eccentric or other fastening means found, d. H. can be fixed.

The hinge arm can be adjusted relative to the hinge cup together with the intermediate plate via a second eccentric passing through this.

The intermediate plate can be guided longitudinally displaceable on a support plate in which the second eccentric is rotatably supported. This allows a separate insertion of the support plate in an otherwise standard executed hinge cup.

Alternatively, the intermediate plate can also be guided longitudinally displaceable in the hinge cup, in which the second eccentric is rotatably supported. In this embodiment, the support plate is saved.

According to a further preferred embodiment, the intermediate plate may have a narrow web portion which is overlapped by the partially cut U-shaped hinge arm.

In the web part, at least one pin can be held in such a way that it projects beyond the web part on both sides and can thereby receive the cross-sectional hinge arm so as to be displaceable transversely to the web part.

For ease of assembly of the at least one pin may be provided in its central region with a corrugation. Thus, the pin can be used with its corrugation in the web portion of the intermediate plate frictionally.

From the FIG. 1 is a side view of the furniture body, ie, for example, a cabinet or a dresser element apparent, the opening is closed by a two hingedly interconnected wings 12, 14 folding flap 16. The front side wall is removed in this illustration to visualize the folder folding elevator 18. On the top wall 20 of the body, the upper wing 12 of the folding flap 16 is articulated in the usual way by two double linker hinge 22, so that it is pivotable about a joint axis defined by the hinges 20.

With the upper wing 12, a lower wing 14 is pivotally connected via a further hinge 26. In the lower wing 14, a hinge cup 28 of the joint 26 is inserted. In the upper wing 12, a hinge cup 29 of the joint 26 is inserted. The hinge 26 defines a pivot axis about which the two wings 12 and 14 of the folding flap are mutually pivotable.

The lifting device 18 already has in FIG DE 201 00 662 U known manner a two-armed lever 34. The lever 34 forms with a fitting part 36 a pivot point 38. The fitting is as out FIG. 1 seen, connected to the lower wing 14. The articulation point 38 also forms a horizontal pivot axis, which is also designated by 38 for the sake of simplicity. Another pivot axis 40 is formed by the upper pivot point of the lever 34. At the shorter lever of the lever arm 34 engages a gas spring 42, which is in turn articulated with its free end on the body.

In the FIG. 2 the folding flap 16 is shown in the open position. The wings 12 and 14 are pivoted upward so that the body is freely accessible.

Based on FIGS. 3 to 6 The structure and function of the hinge 26 will now be described in detail.

The hinge arm 31 is connected to the first hinge cup 28 by a pin 32 (see. Fig. 4 ) pivotally connected. In the opposite end area is the hinge arm 31 via two pins 44 with an intermediate plate 45 transversely connected. The pins 44 are mounted with their central region, which is provided with a corrugation in bores 46 of a narrow web portion 47 of the intermediate plate 45 such that their lateral ends protrude as a pin out of these. The lateral displacement of the hinge arm 31 on the intermediate plate 45 is effected by an eccentric 48, which passes through a bore 49 in the web portion 47 and riveted thereto.

In the illustrated embodiment, the intermediate plate 45 is guided over a separately provided support plate 51 which is fixed in the hinge cup 29 by two pins 52, 53. It is intended to produce the hinge cup 29 made of steel in the usual way. An immediate attachment of the eccentric 50 in the hinge cup 29 would have made a more expensive design of the pot of tin die casting required.

The eccentric 50 is held in a bore 54 of the support plate 51 and riveted in this. The intermediate plate 45 has lateral legs 55 such that it covers the support plate 51 U-shaped: The legs have slots 56 through which the intermediate plate 45 is held on the pins 52, 53 in the hinge cup 29 and guided longitudinally displaceable, wherein the guide is formed by the same pins 52, 53 and by a lower groove 59 which partially surrounds the upper side of the support plate 51 (cf. Fig. 5 ).

The hinge arm 31 and the intermediate plate 45 have in the usual way depending slot-shaped recesses 57, 58 for the heads of the eccentric 48 and 50, respectively.
