Abstract

A drawer device includes a drawer body, a drawer movable linearly therein, and a cover movable relative to the drawer and relative to the drawer body in a lifting direction by a lifting element. A controlled relative movement of the cover can be carried out in the lifting direction by the lifting element and a controller to allow evacuation and/or dehumidification of the drawer interior. The lifting element is arranged to run along two lateral edges of the cover, and each lifting element has a motor, a spindle, and a linear carriage connected to the spindle and linearly movable. A profiled lifting section is operatively connected to a securing element on the drawer body, and can be moved by the lifting element in the lifting direction relative to the cover in a controlled manner by a controller.

First claim

The invention claimed is:

1. A drawer device comprising
a drawer body,
a lifting element,
a drawer movable linearly in the drawer body,
a cover configured to be moved relative to the drawer and relative to the drawer body in a lifting direction by the lifting element to allow a controlled relative movement of the cover to be carried out in the lifting direction by the lifting element and a controller, and to allow the drawer interior to be evacuated and/or dehumidified after the cover is brought into a closed position, and
a lifting profile operatively connected to a fastening element on the drawer body,
wherein the lifting element is arranged to run along two lateral edges of the cover, the lifting element including:
a motor,
a spindle, and
a linear carriage connected to the spindle to thereby be movable linearly, in a fixed manner to the cover,

wherein the lifting profile is configured to be moved by the lifting element in the lifting direction relative to the cover in a controlled manner by the controller relative to a remainder of the lifting element and the cover, to thereby lower the cover onto the drawer and distance the cover from the drawer.

2. The drawer device according to claim 1 , wherein a slit is arranged in at least one side surface of the lifting profile, the slit being operatively connected to an engagement limb on a side surface of the linear carriage.

3. The drawer device according to claim 2 , wherein an angle of the extending direction of the slit on the lifting profile relative to a longitudinal axis of the lifting element and an angle of the engagement limb on the linear carriage relative to a longitudinal axis of the lifting element are between 20° and 60° and are chosen correspondingly identical.

4. The drawer device according to claim 1 , wherein slits are recessed on both sides of the lifting profile on opposing side surfaces.

5. The drawer device according to claim 1 , wherein two linear carriages are linearly displaceably supported on the spindle.

6. The drawer device according to claim 1 , wherein the linear carriage is arranged on a plurality of guides, the guides extending parallel to the spindle.

7. The drawer device according to claim 1 , wherein the spindle is fixed to the cover, the spindle extending through an entire construction of the lifting element between an end block and the motor or a shaft coupling.

8. The drawer device according to claim 1 , further comprising a slide potentiometer fixed to the spindle via a guide and/or fixed to the guide so as to detect a position of the linear carriage.

9. The drawer device according to claim 1 , wherein the lifting profile is operatively connected to a mounting bracket as the fastening element on the drawer body.

10. The drawer device according to claim 1 , wherein the lifting profile has a longitudinal slit configured to receive the fastening element.

11. The drawer device according to claim 1 , wherein the lifting element is one of a pair of lifting elements each arranged on a respective one of the two lateral edges of the cover.

12. A cover of a drawer device with a drawer in a drawer body, the cover being configured to allow an evacuation and/or dehumidification of a drawer interior when the cover is closed, and lifting element being arranged on or within the cover, the lifting element being arranged to run along two lateral edges of the cover in a fixed manner, the lifting element including a motor, a spindle, and a linear carriage fixed to the cover and movable linearly, and the lifting element being operatively connectable to a lifting profile on the drawer body.

13. The cover according to claim 12 , wherein the lifting element is arranged in a recess in the cover.
