Abstract

A closure device for connecting two parts comprises a first closure part, a second closure part which for closing the closure device is attachable to the first closure part in a closing direction, is held at the first closure part in a closed position, for opening the closure device is movable relative to the first closure part in an opening direction different from the closing direction, and after opening of the closure device is removable from the first closure part against the closing direction for separating the closure parts, and magnetic means which act between the first closure part and the second closure part, in order to support the closing of the closure device by providing a force of magnetic attraction. Blocking means ( 25, 253; 32, 332; 27 ) are formed and provided to block a return movement of the second closure part ( 3 ) against the opening direction (O) relative to the first closure part ( 2 ) on separation of the closure parts ( 2, 3 ). In this way, a closure device is provided, in which opening can be effected in a haptically pleasant way and in particular snapping shut immediately after opening is not easily possible.

First claim

1 . A closure device for connecting two parts, comprising
a first closure part, a second closure part, which for closing the closure device is attachable to the first closure part in a closing direction, is held at the first closure part in a closed position, for opening the closure device is movable relative to the first closure part in an opening direction different from the closing direction, and after opening of the closure device is removable from the first closure part against the closing direction for separating the closure parts, magnetic means, which act between the first closure part and the second closure part, in order to support closing of the closure device by providing a force of magnetic attraction, and blocking means which are formed to block a return movement of the second closure part against the opening direction relative to the first closure part on separation of the closure parts.

2 . The closure device according to claim 1 , wherein on opening the force of magnetic attraction at least is attenuated.

3 . The closure device according to claim 1 , wherein after the second closure part has been moved in the opening direction relative to the first closure part, the magnetic means have a magnetically repelling effect.

4 . The closure device according to claim 1 , wherein means are provided which magnetically or by a spring mechanism support the separation of the closure parts after opening of the closure device.

5 . The closure device according to claim 1 , wherein means are provided, which effect a return movement of the closure parts against the opening direction into a position in which the second closure part can be attached to the first closure part in the closing direction for closing the closure device, after the second closure part has been moved against the closing direction relative to the first closure part along a predetermined path for separating the closure parts.

6 . The closure device according to claim 1 , wherein in the closed position the first closure part and the second closure part are mechanically latched with each other such that the second closure part is not movable against the closing direction from the closed position relative to the first closure part.

7 . The closure device according to claim 1 , wherein one of the closure parts includes a detent spring element and the other of the closure parts includes at least one latching protrusion, and wherein in the closed position the detent spring element and the at least one latching protrusion latchingly are in engagement with each other.

8 . The closure device according to claim 1 , wherein the blocking means are formed by a connecting link guideway for at least sectionally guiding the second closure part on opening of the closure device and/or on separation of the closure parts, and wherein the connecting link guideway includes at least one abutment portion which on separation of the closure parts blocks a return movement of the second closure part against the opening direction relative to the first closure part.

9 . The closure device according to claim 8 , wherein the connecting link guideway includes a first connecting link portion for guiding the second closure part relative to the first closure part in the closing direction on closing and a second connecting link guide portion for guiding the second closure part relative to the first closure part in the opening direction on opening.

10 . The closure device according to claim 9 , wherein the connecting link guideway includes a third connecting link portion for guiding the second closure part relative to the first closure part against the closing direction on separation after opening of the closure device.

11 . The closure device according to claim 1 , wherein the blocking means are formed by a snap-in guide which on opening produces a mechanical latching connection of the closure parts for blocking a return movement of the second closure part against the opening direction relative to the first closure part, and wherein on separation the snap-in guide guides the second closure part against the closing direction relative to the first closure part.

12 . The closure device according to claim 1 , wherein the second closure part is connected with an actuating element and guided on the actuating element such that for opening the closure device the actuating element is to be moved relative to the second closure part in an actuating direction different from the opening direction and the movement of the actuating element is converted into a movement of the second closure part in the opening direction.

13 . The closure device according to claim 12 , wherein for opening the closure device the actuating element is to be moved in the or against the closing direction relative to the second closure part.

14 . The closure device according to claim 12 , wherein the second closure part is forcibly guided on the actuating element via a guiding device such that during a movement of the actuating element in the actuating direction the second closure part is moved in the opening direction elative to the first closure part.

15 . The closure device according to claim 14 , wherein the guiding device is formed as oblique guide with at least one oblique guideway or as threaded guide with at least one thread groove.

16 . The closure device according to claim 12 , wherein damping means are formed and provided between the actuating element and the second closure part, in order to attenuate a power transmission from the actuating element to the second closure part during a movement of the actuating element in the actuating direction.

17 . A closure device for connecting two parts, comprising
a first closure part, a second closure part, which for closing the closure device is attachable to the first closure part in a closing direction, is held at the first closure part in a closed position, for opening the closure device is movable relative to the first closure part in an opening direction different from the closing direction, and after opening of the closure device is removable from the first closure part against the closing direction for separating the closure parts, and magnetic means, which act between the first closure part and the second closure part, in order to support closing of the closure device by providing a force of magnetic attraction, wherein the second closure part is connected with an actuating element and guided on the actuating element such that for opening the closure device the actuating element is to be moved relative to the second closure part in an actuating direction different from the opening direction and the movement of the actuating element is converted into a movement of the second closure part in the opening direction.

18 . A furniture element, in particular a sliding door unit or drawer unit, comprising a closure device according to claim 1 .
