Abstract

A device for connecting a movable push element of a piece of furniture or a household appliance to a guide rail. According to the present invention, the device comprises a locking arm with a locking member, wherein in the mounted condition of the device the locking member is designed to be coupled with a locking element, wherein the elongated locking arm is connected by two spaced-apart elastic attachment members to the remainder of the device, which attachment members engage with the locking arm transversely to a longitudinal extension of the locking arm, so that the locking arm is movable in the region of the locking member in a direction transverse to the longitudinal extension of the locking arm and in the direction of the attachment members.

First claim

The invention claimed is:

1. A device for connecting a movable push element of a piece of furniture or a household appliance to a guide rail of a guidance system for the piece of furniture or the household appliance, the device being adapted to be mounted on the movable push element, wherein the device comprises:
a locking arm with a locking member adapted to be coupled with a corresponding locking part,
wherein the locking arm is an elongated element,
wherein the locking arm is connected by precisely two spaced-apart, curved attachment members to a remainder of the device,
wherein the two spaced apart, curved attachment members engage with the locking arm transversely with respect to a longitudinal extension of the locking arm,
wherein the two spaced apart, curved attachment members each have a curved shape, extending along a respective length of each of the two spaced apart, curved attachment members whereby the two curved attachment members each extend from respective first ends thereof proximate the remainder of the device along a curved shape toward respective second ends thereof proximate the locking arm, and
wherein the curved shapes of the two spaced apart, curved attachment members are curved in opposite directions from one another, and
wherein the two space apart, curved attachment members are elastic so that the locking arm is movable in a region of the locking member in a direction transverse with respect to the longitudinal extension of the locking arm and in a direction of the two attachment members.

2. The device according to claim 1 , wherein the locking arm comprises a control element, which is angled relative to a remaining elongated portion of the locking arm, so that the locking arm is movable by the control element.

3. The device according to claim 1 , wherein during a positioning of the locking arm, the locking arm performs a movement transversely with respect to the longitudinal extension of the locking arm and/or along the longitudinal extension of the locking arm, and wherein during the positioning, a movement path transverse with respect to the longitudinal extension of the locking arm is comparatively larger than a movement path lengthwise with respect to the longitudinal extension of the locking arm.

4. The device according to claim 1 , wherein the locking member is a single locking tooth.

5. The device according to claim 1 , wherein the two space apart, curved attachment members are substantially cuboidal wall elements.

6. The device according to claim 1 , wherein a thickness of at least one of the two space apart, curved attachment members decreases from a first end thereof proximate the remainder of the device toward a second end thereof proximate the locking arm.

7. The device according to claim 1 , wherein a thickness of a first one of the two space apart, curved attachment members is larger than a thickness of a second one of the two space apart, curved attachment members.

8. The device according to claim 1 , further comprising a device locking element, which is present as a single structural part separate from the remainder of the device,
wherein the device locking element comprises a mounting element, the mounting element adapted to mount the device locking element on an end face of a guide rail, and
wherein the device locking element is adapted to interlock with the locking member of the device in a mounted condition of the device.

9. The device according to claim 1 , further comprising a spring that pretensions the coupling of the locking member to the locking part in a direction along the longitudinal extension of the locking arm.

10. A guidance system comprising the device according to claim 1 .

11. A piece of furniture or a household appliance including the guidance system according to claim 10 .

12. The device according to claim 3 , wherein the locking arm performs a movement parallel to the longitudinal extension of the locking arm during the positioning of the locking arm.
