Abstract

An arrangement for tipping over prevention of a chest of drawers may include a drawer locking arrangement and an anchoring bracket. The drawer locking arrangement may include at least two locking members each configured to selectively engage an associated drawer, a guiding rail adapted to be mounted to a wall of the chest of drawers, a stop member configured to restrict movement of the at least two locking members such that only one drawer at a time is openable, and a driver connected to the guiding rail and/or the stop member and configured to indirectly interact with the at least two locking members. The anchoring bracket may include a first bracket member adapted to be mounted to the wall of the chest of drawers and a second bracket member including a guiding slot structured and arranged to receive a protrusion of the driver, thereby providing a cam mechanism.

First claim

The invention claimed is:

1. An arrangement for tipping over prevention of a chest of drawers, the arrangement comprising a drawer locking arrangement and an anchoring bracket, wherein:
the drawer locking arrangement includes:
at least two locking members configured to selectively allow only one drawer at a time to be opened, each locking member of the at least two locking members configured to selectively engage an associated drawer;
a guiding rail adapted to be mounted to a wall of the chest of drawers;
a stop member configured to restrict movement of the at least two locking members whereby only one drawer at a time is openable; and
a driver connected to the guiding rail and/or the stop member, the driver configured to indirectly interact with the at least two locking members;

the anchoring bracket includes:
a first bracket member adapted to be mounted to the wall of the chest of drawers; and
a second bracket member including a guiding slot structured and arranged to receive a protrusion of the driver, thereby providing a cam mechanism;

the second bracket member is movable in relation to the first bracket member to a first position and to a second position, and in the second position the second bracket member is adapted to be fixedly anchored to a structure separate from the chest of drawers;
when the second bracket member is in the first position, the driver is set to a first driver position in which the at least two locking members are adapted to allow opening of one drawer only; and
when the second bracket member is in the second position, the driver is set to a second driver position in which the stop member and/or the drawer locking arrangement is in a position adapted to allow all drawers to be selectively opened.

2. The arrangement according to claim 1 , wherein the guiding slot includes a first slot portion coinciding with a moving direction of the second bracket member, and a second slot portion forming an angle α to the first slot portion.

3. The arrangement according to claim 1 , wherein the second bracket member, when set to the second position, is moved in a direction extending transverse to a longitudinal extension of the guiding rail.

4. The arrangement according to claim 1 , wherein the second bracket member is biased in a direction towards the first bracket member.

5. The arrangement according to claim 1 , wherein:
the second bracket member further includes a guiding portion and a mounting portion; and
the mounting portion is pivotable in relative to the guiding portion.

6. The arrangement according to claim 1 , wherein the guiding rail is adapted to be movable relative to the wall of the chest of drawers.

7. A chest of drawers, comprising an arrangement for tipping over prevention according to claim 1 .

8. The chest of drawers according to claim 7 , further comprising a plurality of drawers, a plurality of guiding and support rails, and a plurality of walls including the wall, wherein:
each drawer of the plurality of drawers is supported by associated guiding and support rails which are arranged in opposing walls of the plurality of walls; and
at least one of the plurality of guiding and support rails is arranged on top of and across the guiding rail of the drawer locking arrangement.

9. An arrangement for tipping over prevention of a chest of drawers, the arrangement comprising a drawer locking arrangement and an anchoring bracket, wherein:
the drawer locking arrangement includes:
at least two locking members configured to selectively allow only one drawer at a time to be opened, each locking member of the at least two locking members configured to selectively engage an associated drawer;
a guiding rail adapted to be mounted to a wall of the chest of drawers;
a stop member configured to restrict movement of the at least two locking members whereby only one drawer at a time is openable; and
a driver connected to the guiding rail and/or the stop member, the driver configured to indirectly interact with the at least two locking members;

the anchoring bracket includes:
a first bracket member adapted to be mounted to the wall of the chest of drawers; and
a second bracket member including a guiding slot structured and arranged to receive a protrusion of the driver, thereby providing a cam mechanism;

the second bracket member is movable in relation to the first bracket member to a first position and to a second position, and in the second position the second bracket member is adapted to be fixedly anchored to a structure separate from the chest of drawers;
when the second bracket member is in the first position, the driver is set to a first driver position in which the at least two locking members are adapted to allow opening of one drawer only;
when the second bracket member is in the second position, the driver is set to a second driver position in which the stop member and/or the drawer locking arrangement is in a position adapted to allow all drawers to be selectively opened;
the guiding slot includes (i) a first slot portion coinciding with a moving direction of the second bracket member and (ii) a second slot portion forming an angle α to the first slot portion; and
the second bracket member is biased in a direction towards the first bracket member.

10. The arrangement according to claim 9 , wherein the second bracket member, when set to the second position, is moved in a direction extending transverse to a longitudinal extension of the guiding rail.

11. The arrangement according to claim 9 , wherein:
the second bracket member further includes a guiding portion and a mounting portion; and
the mounting portion is pivotable in relative to the guiding portion.

12. The arrangement according to claim 9 , wherein the guiding rail is adapted to be movable relative to the wall of the chest of drawers.

13. A chest of drawers, comprising an arrangement for tipping over prevention according to claim 9 .

14. The chest of drawers according to claim 13 , further comprising a plurality of drawers, a plurality of guiding and support rails, and a plurality of walls including the wall, wherein:
each drawer of the plurality of drawers is supported by associated guiding and support rails which are arranged in opposing walls of the plurality of walls; and
at least one of the plurality of guiding and support rails is arranged on top of and across the guiding rail of the drawer locking arrangement.

15. An arrangement for tipping over prevention of a chest of drawers, the arrangement comprising a drawer locking arrangement and an anchoring bracket, wherein:
the drawer locking arrangement includes:
at least two locking members configured to selectively allow only one drawer at a time to be opened, each locking member of the at least two locking members configured to selectively engage an associated drawer;
a guiding rail adapted to be mounted to a wall of the chest of drawers;
a stop member configured to restrict movement of the at least two locking members whereby only one drawer at a time is openable; and
a driver connected to the guiding rail and/or the stop member, the driver configured to indirectly interact with the at least two locking members;

the anchoring bracket includes:
a first bracket member adapted to be mounted to the wall of the chest of drawers; and
a second bracket member including a guiding slot structured and arranged to receive a protrusion of the driver, thereby providing a cam mechanism;

the second bracket member is movable in relation to the first bracket member to a first position and to a second position, and in the second position th
