Abstract

A pull-out guide for a microwave cooking appliance or an industrial oven includes a body rail and a running rail, that is able to move relative thereto, for depositing a carrier, and a microwave shield for shielding the pull-out guide from microwaves. The running rail is only partially shielded.

Claims

1-15. -15. (canceled)

16. A pull-out guide for a microwave cooking appliance or an industrial furnace, the pull-out guide comprising:

a body rail;

a running rail configured to be movable relative to the body rail, wherein the running rail is further configured for depositing a support; and

a microwave shield configured to shield the pull-out guide against microwaves, wherein the running rail is only partially shielded.

17. The pull-out guide of claim 16, wherein the microwave shield is formed in at least two parts, wherein a first part is attached to the body rail and a second part is attached to the running rail.

18. The pull-out guide of claim 17, wherein the first part of the microwave shield is a first U-shaped profile rail with lateral legs and the second part of the microwave shield is a second U-shaped profile rail with lateral legs, wherein the first and second U-shaped profile rails engage in one another and, at least in some sections, overlap one another laterally with their lateral legs.

19. The pull-out guide of claim 18, wherein the first U-shaped profile rail and the second U-shaped profile rail are tapered in a longitudinal direction of the pull-out guide.

20. The pull-out guide of claim 17, wherein the first part of the microwave shield is at least a first strip-shaped shielding plate and the second part of the microwave shield is at least a second strip-shaped shielding plate, wherein the first and second strip-shaped shielding plates are arranged laterally on the pull-out guide and, at least in a retracted state of the pull-out guide, overlap one another or bear against one another along a respective longitudinal edge.

21. The pull-out guide of claim 20, wherein the longitudinal edges of the first and second strip-shaped shielding plates run in a sloping manner with respect to a pull-out direction.

22. The pull-out guide of claim 17, wherein the first part of the microwave shield is a U-shaped profile rail with lateral legs and the second part of the microwave shield comprises a plurality of contact elements contacting the U-shaped profile rail in a contact area.

23. The pull-out guide of claim 22, wherein the plurality of contact elements are attached to the body rail and/or to the U-shaped profile rail.

24. The pull-out guide of claim 22, wherein the contact area comprises a channel, into which the plurality of contact elements protrude.

25. The pull-out guide of claim 16, wherein the microwave shield is formed in one piece and is attached to the running rail.

26. The pull-out guide of claim 25, wherein the microwave shield is a U-shaped profile rail with lateral legs having a plurality of contact elements contacting the body rail.

27. The pull-out guide of claim 26, wherein the plurality of contact elements each have a latching head, which is inserted in latching openings of the U-shaped profile rail, and contact springs connected thereto.

28. The pull-out guide of claim 26, wherein the lateral legs of the U-shaped profile rail are inclined relative to one another.

29. The pull-out guide of claim 25, wherein the microwave shield is a rectangular profile rail surrounding the body rail and the running rail and the rectangular profile rail has a slot along one longitudinal side.

30. A microwave cooking appliance or industrial furnace, comprising:

at least one pull-out guide, comprising

a body rail;

a running rail configured to be movable relative to the body rail, wherein the running rail is further configured for depositing a support; and

a microwave shield configured to shield the pull-out guide against microwaves, wherein the running rail is only partially shielded.
