Abstract

A touch-latch device used in furniture especially for initial opening of an opening furniture component, comprising a housing with an axially arranged groove, in which a push element is slidingly arranged, said element being actuated by a helical spring and controllable by a dual-position guide mechanism comprising a cam groove guide and an S-pin, wherein the device comprises a push element controlled by two dual-position guide mechanisms, wherein each cam groove guide of a dual-position guide mechanism is arranged on a lateral side of the push element and the S-pin is pivoted in the lateral wall of the groove of the housing, and that the push element is provided at its free end with a regulation plug arranged by means of a bolted joint, said plug being displaceable in axial direction, wherein the axial displacement of the regulation plug is limited by an arrester arranged therein.

Claims

1. A touch-latch device used in furniture especially for initial opening of an opening furniture component, such as drawers or doors, without handles and also for holding such component in a closed position, comprising a housing with an axially arranged groove, in which a push element is slidingly arranged, said element being actuated by a helical spring and controllable by a dual-position guide mechanism comprising a cam groove guide and an S-pin, characterized in that the device (1) comprises a push element (4) controlled by more than one, preferably two dual-position guide mechanisms, wherein each cam groove guide (8) of a dual-position guide mechanism is arranged on a lateral side (10) of the push element (4) and the S-pin (9) is pivoted in the lateral wall of the groove (11) of the housing (2), and that the push element (4) is provided at its free end with a regulation plug (13) arranged by means of a bolted joint (14, 15), said plug (13) being displaceable in axial direction, wherein the axial displacement of the regulation plug (13) is limited by an arrester (16) arranged therein.

2. Touch-latch device according to claim 1, characterized in that the arrester (16) is a double-sided riveted bolt of a predetermined length arranged in a through hole (18) of a threaded extension (14) and the regulation plug (13)

3. Touch-latch device according to claim 1, characterized in that each lateral wall of the groove (11) is provided with a recess (12) with a hole (19) for a pivotable reception of a leg of the S-pin (9), wherein the second leg of the S-pin (9) projects into the interior of the groove (11) of the housing (2) and extends into the cam groove guide (8) of the push element (4).

4. Touch-latch device according to claim 1, characterized in that each S-pin (9) is arranged within the hole (19) in a way that the webs and the rectangular legs of both S-pins (9) perpendicular thereto lie in the same plane that coincides with the axial plane of the device in idle mode.

5. Touch-latch device according to claim 1, characterized in that an additional elements (17) are arranged at the free end of the regulation plug (13).

6. Touch-latch device according to claim 5, characterized in that an additional element (17) is a rubber plug.

7. Touch-latch device according to claim 5, characterized in that an additional element (17) is a magnet plug.

8. Touch-latch device according to claim 3, characterized in that each S-pin (9) is arranged within the hole (19) in a way that the webs and the rectangular legs of both S-pins (9) perpendicular thereto lie in the same plane that coincides with the axial plane of the device in idle mode.
