Description

DRAWER LOCKING DEVICE, FIXED HANDLE

  MANEUVER, DRAWER AND DRAWER FURNITURE INCLUDING SUCH

DEVICE

  The invention relates to a device for locking a drawer with a fixed operating handle integral with the

front of the drawer.

  Drawer locking devices are already known comprising at least one latch bolt mounted on the drawer, movable in longitudinal translation perpendicular to the direction of movement of the drawer and extending projecting outside the template of the drawer to cooperate with a shoulder or a strike from the frame

  cabinet or chassis on which the drawer is mounted.

  Also, such a device generally comprises means for returning the bolt to the extreme locking position and unlocking control means accessible from

the front of the drawer.

  These devices make it possible to automatically lock the drawer when it comes into the closed position. Such locking devices are for example used to keep locked drawers of movable furniture with drawers of great length capable of containing heavy loads such as they are encountered. for example in the field of tool or accessory storage drawers used in machine shops or the like Indeed, this avoids a knock-on effect in the event of the untimely start of tilting of the piece of furniture which appears when or more drawers are deployed in the open position and the load it supports

  causes the furniture to tilt forwards.

  Thus, European patent application O 154 605 describes a locking device whose bolt movable in longitudinal translation perpendicular to the direction of movement of the drawer is controlled by a button which protrudes from the front face of the drawer. In such a device, the unlocking is obtained by pushing the button towards the rear of the drawer. Such an action is therefore carried out in the opposite direction to the pulling movement which then allows the drawer to be opened. It is therefore understood that the unlocking and the opening of the drawer require opposite directions and in practice require the use of both hands In addition, a specific housing must be provided in the front side corner of the drawer for

  guide and support the knob and the sliding bolt.

  We also know of drawers -

  in particular storage units for tools or machine shop accessories, the drawers of which comprise a fixed operating handle which comprises a pulling face of the drawer generally oriented towards the rear of the drawer and delimited by at least one edge extending parallel to the front face of the drawer, a hollow space extending at least behind the traction face for the passage of the hand In a particular embodiment, the handle is formed from a profile attached to the front face of each drawer and which therefore extends projecting relative to this front face and to the front face of the cabinet. These projecting handles thus constitute a risk for users who may bump or

  hang on or more simply be bothered by these handles.

  The invention therefore aims to remedy these drawbacks of locking devices, drawers and furniture

with drawers of the prior art.

  Thus, the subject of the invention is a locking device for a drawer which allows the drawer to be unlocked and opened with one hand thanks to simple maneuvers carried out in non-contradictory directions. More particularly, the object of the invention is to propose a locking device which can be actuated in a simple manner during unlocking and which

  is better suited to the subsequent opening of the drawer.

  Also, the object of the invention is to provide such a simple and inexpensive locking device, in particular which does not require specific housing provided for this purpose in the drawer and can be manufactured with a number

  minimum parts, each part being simple to manufacture.
