Lighting unit for a large electrical device
View Patent ↗A lighting unit for a large electrical household appliance includes a base part configured to receive a luminous element and having positive engagement elements, and a top part configured for attachment to the base part through displacement of the top part longitudinally in a connection plane relative to the base part. The top part has in displacement direction a front region which is provided with two gripping hooks for engagement with the positive engagement elements of the base part, with the gripping hooks engaging below the positive engagement elements.
1. A lighting unit for a housing wall of a large electrical household appliance, comprising:
a base part configured to receive a luminous element and having positive engagement elements; and
a top part configured to attach to the base part by a displacement of the top part relative to the base part in a connection plane, said top part having a front region provided with two gripping hooks for engagement with the positive engagement elements of the base part after the displacement, with the gripping hooks engaging below the positive engagement elements,
wherein the connection plane is parallel to the housing wall and the displacement is towards the two gripping hooks.
2. The lighting unit of claim 1 , constructed for a household refrigeration appliance.
3. The lighting unit of claim 1 , wherein the gripping hooks releasably engage with the positive engagement elements in a non-destructive manner.
4. The lighting unit of claim 1 , wherein the base part has gripping hooks for engagement in at least one recess provided in the top part.
5. The lighting unit of claim 1 , further comprising at least one latching mechanism, which acts between the top part and the base part for fixing the top part relative to the base part.
6. The lighting unit of claim 1 , wherein the top part and the base part are secured in their engagement position with a force fit in opposition to an engagement direction.
7. The lighting unit of claim 6 , wherein the force fit is realized by spring force.
8. The lighting unit of claim 6 , further comprising at least one latching mechanism, which acts between the top part and the base part for fixing the top part relative to the base part, said latching mechanism having a stiff latching projection on the base part and a stiff latching segment on the top part, wherein the latching projection of the top part and the latching segment of the base part slide onto one another when the top part is displaced longitudinally relative to the base part to thereby initially cause an elastic deflection of the top part to establish the force fit to secure the engagement position, until the latching segment is able to engage behind the latching projection.
9. The lighting unit of claim 1 , wherein the top part is a flat and smooth cover with a surface configured to be parallel to the housing wall.
10. The lighting unit of claim 1 , wherein the base part is a backing piece.
11. A refrigeration appliance, comprising:
a housing wall;
at least one lighting unit attached to the housing wall and including
a base part configured to receive a luminous element and having positive engagement elements, and
a top part configured to attach to the base part by a displacement of the top part relative to the base part in a connection plane, said top part having a front region formed with two gripping hooks for engagement with the positive engagement elements of the base part after the displacement, with the gripping hooks engaging below the positive engagement elements,
wherein the connection plane is parallel to the housing wall and the displacement is towards the two gripping hooks.
12. A refrigeration appliance of claim 11 , constructed in the form of a household refrigerator or freezer.
13. The refrigeration appliance of claim 11 , wherein the gripping hooks releasably engage with the positive engagement elements in a non-destructive manner.
14. The refrigeration appliance of claim 11 , wherein the base part has gripping hooks for engagement in at least one recess provided in the top part.
15. The refrigeration appliance of claim 11 , wherein the lighting unit includes at least one latching mechanism, which acts between the top part and the base part for fixing the top part relative to the base part.
16. The refrigeration appliance of claim 11 , wherein the top part and the base part are secured in their engagement position with a force fit in opposition to an engagement direction.
17. The refrigeration appliance of claim 16 , wherein the force fit is realized by spring force.
18. The refrigeration appliance of claim 16 , wherein the lighting unit includes at least one latching mechanism, which acts between the top part and the base part for fixing the top part relative to the base part, said latching mechanism having a stiff latching projection on the base part and a stiff latching segment on the top part, wherein the latching projection of the top part and the latching segment of the base part slide onto one another when the top part is displaced longitudinally relative to the base part to thereby initially cause an elastic deflection of the top part to establish the force fit to secure the engagement position, until the latching segment is able to engage behind the latching projection.
19. The refrigeration appliance of claim 11 , wherein the top part is a flat and smooth cover with a surface parallel to the housing wall.
20. The refrigeration appliance of claim 11 , wherein the base part is a backing piece.
