Description

SPECIFICATION Flap Holder The invention relates to a flap holder which comprises two scissors guides which are pivotally connected one to the other and the respective end of the one is pivotally connected to the flap and the respective end of the other is pivotally connected to the body of the article of furniture.
The disadvantage of these known flap fittings resides in that they do not possess a braking device. Admittedly flap fittings are known in which a guide for a slide brake is attached to the body of the article of furniture, wherein a connecting guide member pivotally connected to the brake body is pivotally connected to the flap.
These fittings possess a very limited range of movement, for which reason the connecting guide member must be pivotally connected to the flap close to the pivot axis of the latter. Such fittings are not suitable for large heavy flaps.
The invention has the purpose to improve a flap holder of the kind referred to above by the fact that it is equipped with a brake. In this way the flap holder according to the invention comprises the advantages of both kinds of construction, that is to say satisfactory braking properties and a large range of movement, so that the flap is held by the fitting remote from the pivot axis of the former. This is attained according to the invention in that one of the scissors guides (control guide) is provided with a guide for a sliding brake body which is connected by means of a connecting guide member to the other scissors guide (lever guide) operating as a lever.
The invention is concerned furthermore with elaborations of this flap fitting.
The drawing illustrates the subject of the invention with reference to a constructional form given by way of example. There are shown in: Fig. 1 the novel fitting, in side view, Figs. 2 and 3 a section through the braking device, during the effective and the ineffective position thereof, and Fig. 4 a detail.
A control guide 3 is pivotally mounted by means of a bearing 2 in the interior of the body of an article of furniture, and is connected to a lever guide 5 by means of a pivot joint 4; the lever guide 5, in turn, is pivotally attached to a flap 7 by means of a bearing 6. The lever guide 5 comprises an extension 8 which projects beyond the pivot joint 4 and the end of which is connected by means of a connecting guide member 9 to the braking device which is generally denoted by 10. The pivot joint 4 is provided with a rotation spring 11, as in Fig. 1, the limbs of which are moved against one another when the flap is open, so that it is then under bias tension. It endeavours to rotate the lever guide 5 in a clockwise direction, according to Fig. 1, about the pivot joint 4.This spring 11 does not only facilitate the folding together of the guides 3 and 5 during the closing of the flap 7, but also constitutes a brake for the fitting, shortly before the guides 3 and 5 attain their extended position and the slide brake 10 is no longer effective.
As may be seen from Fig. 1. the lever guide 5 is mounted at a relatively large distance from the pivot axis 12 of the flap 7, so that a good support of the plate 7 results therefrom.
The slide brake generally denoted by 10 is illustrated on a larger scale in Figs. 2 and 4. the brake body is divided along an inclined plane 1 3.
The active portion 14 which is connected to the connecting guide member 9 in a rotatable member is displaceable relatively to the passive portion 1 5 along the wedge surface 1 3. During opening and closing the flap 7, the active portion 14 is displaced within the control guide 3 by the connecting guide member 9 and drives the passive portion 1 5 by means of abutments. The control guide 3 consists of a slit tube of rectangular crosssection. The connecting guide member 9 moves in the slit of the tube.The abutments which limit the relative movement between the active and the passive portion consist of a projection 1 6 of the passive portion 1 5 which extends into a pocket 1 7 of the active portion 14, and of a screw 1 8 the point of which co-operates with an inclined surface 1 9 of the passive portion 1 5. The screw 1 8 extends through the slit of the tube of the control guide 3 and is directed perpendicular to the brake movement.
The arrangement is made so that the braking force can be adjusted by means of the screw 18, screwing out increasing the brak.ing effect. In this way the effect is obtained by way of prevention that the braking effect is lost by the screw being released.
In order to ensure a relative movement between the active and the passive portion, the passive portion 1 5 which is illustrated in elevation in Fig. 4 comprises projections 20 by which it rests under bias tension on the side walls of the slit tube which forms the control guide 3.
In order to increase the freedom of movement, it is advantageous to crank the lever guide 5 in the vicinity of the pivot joint 4.
The invention is not limited to the constructional example illustrated; in place of the brake shown, another brake body may be provided which may also embrace the control guide 3. It is also possible to construct the lever guide 5 in the form of a one-armed lever and to connect the connecting guide member pivotally to the lever guide 5 between the joint 4 and the bearing 6.
