Abstract

The invention relates to a laboratory cabinet device for storing laboratory samples with a magnetic closure for the door. It in particular relates to a tempering cabinet for tempering laboratory samples, in particular, an incubator for the growth of cell cultures.

Claims (14)

1. Laboratory cabinet device ( 1 ) for storing laboratory samples, comprising a chamber housing ( 2 ) with a front side ( 3 ) and a chamber opening ( 4 ) of the front side through which the chamber interior ( 5 ) is accessible, a chamber door ( 6 ) for closing the chamber opening in a closed position of the chamber door,

closure device ( 10 , 7 a , 7 b ) for holding the chamber door at the front side in the closed position by a magnetic holding force, wherein the closure device comprises an actuating element ( 10 ), a first holding element ( 7 a ) and a second holding element ( 7 b ),

wherein the first holding element ( 7 a ) is fixed to the actuating element ( 10 ) and the second holding element ( 7 b ) is fixed to the front side ( 3 ), and the actuating element ( 10 ) is pivotally mounted to the chamber door ( 6 ) so that the actuating element ( 10 ) is pivotally movable between a first open pivoted position (P 1 ), in which the first and second holding elements cannot exert magnetic holding force on each other, and a second, closed pivoted position (P 2 ), in which the first and second holding elements can exert the magnetic holding force on each other,

wherein the actuating element ( 10 ) extends parallel to the main plane ( 6 a ) of the chamber door ( 6 ) and has an end which is formed as a grip tab portion ( 11 ) which in the second pivoted position projects beyond the edge ( 6 b ) of the chamber door ( 6 ) so that in the closed position of the chamber door and in the second pivoted position (P 2 ) of the actuating element ( 10 ) the magnetic holding force of the closure device ( 10 , 7 a , 7 b ) can be overcome by the user both by rotating the actuating element ( 10 ) from the second pivot position (P 2 ) to the first pivot position (P 1 ) and by pulling the chamber door by means of the grip tab portion ( 11 ) in a direction (A) perpendicular to the main plane ( 6 a ) of the chamber door ( 6 ).

2. A laboratory cabinet device according to claim 1 , wherein the first and/or the second holding element comprise or consist of a permanent magnet.

3. A laboratory cabinet device according to claim 1 , wherein the actuating element is a plate-shaped component ( 10 ), whose main plane runs parallel to a pivoting plane and to the main plane ( 6 b ) of the chamber door ( 6 ).

4. Laboratory cabinet device according to claim 1 , wherein the actuating element comprises a hole or recess through which a pivot member oriented parallel to the pivot axis of the actuating element is disposed and pivotally connects the actuating element to the chamber door.

5. Laboratory cabinet device according to claim 1 , wherein the first holding element is arranged on the lower side of the grip tab section ( 11 ), which faces towards the chamber door in the first pivoted position (P 1 ).

6. Laboratory cabinet device according to claim 1 , wherein the grip tab portion comprises at least one tab portion which, in the second pivoted position (P 2 ), projects beyond the edge ( 6 b ) of the chamber door in a pivoting plane of the actuating element.

7. Laboratory cabinet device according to claim 6 , wherein the at least one tap portion includes a first wing portion ( 11 a ) and a second wing portion ( 11 b ) protruding laterally from the actuating element perpendicular to the longitudinal direction (L) of the actuating element, which corresponds to the radial direction of the pivoting movement.

8. Laboratory cabinet device according to claim 1 , wherein the closure device comprises a position latching device ( 21 , 25 ) by means of which the actuating element engages at least in the second pivoted position and/or at least also engages in a first pivoted position.

9. Laboratory cabinet device according to claim 8 , wherein the position latching device comprises at least one latching element ( 21 a ) and at least one latching portion ( 25 a ), which latch together at least in the first and/or in the second pivoted position.

10. Laboratory cabinet device according to claim 1 , which is a tempering cabinet for tempering laboratory samples.

11. Laboratory cabinet device according to claim 10 , which is an incubator for cell culture.
