Abstract

The device (10) for laterally centring a drawer (13) or the like on a pull-out guide (11) comprises a first and a second coupling part (26, 27) respectively connectable to a hooking device (12) for fastening the drawer (13) and to the pull-out guide (11); at least one of the coupling parts (26, 27) is conformed with elastically yieldable means in a lateral direction for causing a forced engagement and/or a shape engagement between the coupling parts (26, 27) such as to compensate for any lateral play between the hooking device (12) and the pull-out guide (11).

Claims

1. Centring device for laterally centring a drawer, the centring device comprising:

a pull out guide pre-mountable to a body of a piece of furniture, the pull out guide including an extractable part having a hole; and

a hooking device fixable to a drawer, where the drawer is fixable to the pull out guide by the hooking device, the hooking device having a hooking member insertable in a mounting position in the hole of the extractable part and a lever for the manual actuation of the hooking member between a hooking position in which the hooking member can engage in the hole of the extractable part and a release position in which the hooking member is disengaged from the hole of the extractable part; and

a first and a second coupling part respectively connectable to the hooking device and to the pull-out guide, wherein at least one of the first and the second coupling parts is conformed with an elastic yieldable device, the elastic yieldable device providing yieldability in lateral direction to allow a forced or a shaped engagement between the first and the second coupling parts, the forced or shaped engagement compensating for any lateral play between the hooking device and the pull-out guide.

2. The centring device of claim 1, wherein the elastic yieldable device of the first and the second coupling parts includes a wedge-shaped centring element connectable to one of the hooking device and the pull-out guide, and an engagement seat for receiving the wedge-shaped centring element on the other of the hooking device and the pull-out guide.

3. The centring device of claim 2, wherein the centring element is fork-shaped having two longitudinal arms spaced apart by a central longitudinal slit, the two longitudinal arms being elastically yieldable in lateral direction.

4. The centring device of claim 2, wherein the wedge-shaped centring element extends from the hooking device according to a longitudinal pull-out axis of the pull out guide.

5. The centring device of claim 2, wherein the engagement seat has slanted side surfaces diverging towards a front end of the pull out guide which cooperate with slanted side surfaces of the wedge-shaped centring element to cause the lateral elastic yieldability.

6. The centring device of claim 5, wherein the slanted side surfaces of the wedge-shaped centring element extend only on a part at an end of the centring element, converging towards the same end, with an angle greater than that of the slanted side surfaces of the engagement seat in reference to a respective longitudinal axis.

7. The centring device of claim 2, wherein the centring element and the engagement seat are conformed and arranged to be oriented substantially axially aligned relative to each other in a mounting condition of the drawer.

8. The centring device of claim 2, wherein the second coupling part is provided in an added part fixable to a front end of the pull-out guide.

9. The centring device of claim 2, wherein the first coupling part is connectable to the hooking device by a lateral adjustment device.

10. The centring device of claim 9, wherein the lateral adjustment device includes a threaded pin integral with the first coupling part and a drive female thread supported in a rotatable, but not axially movable, way by a body of the hooking device.

11. Hooking device for fixing a drawer to a longitudinal pull out guide pre-mountable to a body of a piece of furniture, the hooking device comprising:

a body fixable to a drawer;

a hooking member insertable in a hole provided in the pull out guide;

a lever for the manual actuation of the hooking member between a hooking position in which the hooking member can engage in the hole provided in the pull out guide and a release position in which the hooking member is disengaged from the hole provided in the pull out guide; and

a first coupling part having a wedge-shaped centring element connectable thereto, where the centring element is fork-shaped having two longitudinal arms spaced apart by a central longitudinal slit, the two longitudinal arms being elastically yieldable in lateral direction to allow a forced or a shaped engagement between the first coupling part and the pull out guide, the forced or shaped engagement compensating for any lateral play between the hooking device and the pullout guide.

12. A method for laterally centring a drawer on a pull out guide, the method comprising the steps of:

pre-mounting a pull out guide on a body of a piece of furniture, the pull out guide comprising a hole; and

connecting a drawer to the pull-out guide by a hooking device comprising a hooking member and a lever, the lever configured for providing manual actuation of the hooking member between a hooking position in which the hooking member can engage in the hole of the pull out guide and a release position in which the hooking member is disengaged from the hole of the pull out guide, wherein the step of connecting comprises the steps of;

attaching a first coupling part to the hooking device;

attaching a second coupling part to the pull out guide; and

causing a forced or shaped engagement between the first and the second coupling parts by subjecting at least one of the first and the second coupling parts to an elastic deformation in a lateral direction so as to compensate any lateral play between the hooking device and the pull out guide.
