Abstract

A worktop or furniture unit, made up of at least one glass ceramic sheet and elements for its operation, at least one of said elements being positioned on a two-dimensional or three-dimensional mobile support coupled to a circuit breaker, so that, when the support is in a first position, said element lies facing one face of the sheet at a distance from the sheet and can be activated, and, when the support is in a second position, obtained by a movement thereof, in which position at least one of the ends of the support is moved by, or lies at, a distance with respect to the sheet and perpendicular thereto and is moved by, or lies at, a distance with respect to its first position, said element is deactivated.

First claim

The invention claimed is:

1. An item for domestic and/or furnishing use, made up of at least one glass ceramic sheet and elements for its operation, at least one of said elements being positioned on a two-dimensional or three-dimensional mobile support coupled to a safely device, so that, when the support is in a first position, said element lies facing one face of the sheet at a distance of at most 10 cm from the sheet and can be activated, and, when the support is in a second position, obtained by a movement thereof, in which position at least one end of the support is moved by, or lies at, a distance of at least 2 mm with respect to the sheet and perpendicular thereto and is moved by, or lies at, a distance of at least 5 cm with respect to its first position, said element is deactivated.

2. The item as claimed in claim 1 , wherein at least some of the elements, or even all the elements, of use in the operation of the sheet or of the item are positioned on the mobile support, said elements lying facing one face of the sheet, at a distance, perpendicular to said face and between said face and the nearest end of each of said elements, of at most 10 cm from the sheet when the support is in said first position, and in that at least some of said elements are deactivated when the support is in said second position, advantageously through the action of the safety device.

3. The item as claimed in claim 1 , wherein the mobile support takes the form of a plate or of a casing or housing, preferably situated beneath the sheet, the support being capable of translational and/or rotational movement, horizontally and/or vertically, so as to move it at least partially away from the sheet in the second position.

4. The item as claimed in claim 1 , wherein, when the support is in the first position, the element(s) situated on the support lie facing the lower face of the sheet at a distance of at most 4 cm, from the sheet and, when the support is in the second position, at least one of the ends of the support, or even the entirety of the support, lies at a distance of at least 5 cm in relation to its first position, in particular lies vertically at a distance of at least 10 cm from its first position, and/or lies vertically at a distance of at least 2 mm from the sheet and horizontally at a distance of at least 5 cm from its first position.

5. The item as claimed in claim 1 , wherein the safety device is formed of at least one manual or automatic circuit breaker, triggered in particular by the movement of the plate and/or by a short circuit and/or of a contactor and/or of a breaker switch.

6. The item as claimed in claim 1 , wherein the movement of the support is about an axis of rotation, situated, for example, along an opposite edge to the edge intended to be moved away from the sheet, with an angle of at least 2.5° with respect to the first position of the support, or along guide rails or slides, where appropriate allowing a movement that is vertical and horizontal, for example approximately S-shaped.

7. The item as claimed in claim 1 , wherein the item it comprises, or in that the sheet is coupled to, a safety device, such as a brake, to prevent the operator from becoming trapped or prevent excessively sharp movement of the support as it is actuated, or such as one or more end stops or one or more latches or one or more devices for immobilizing the support in at least one of its positions of use.

8. The item as claimed in claim 1 , wherein the glass ceramic sheet occupies more than 50% of the surface area of one face of said item, said sheet in particular resting on at least one casing or one or more support legs, without a seal in between.

9. The item as claimed in claim 1 , wherein the sheet is a monolithic sheet having a thickness of less than 15 mm an expansion coefficient of less than 30×10-7 K-1 between 20° C. and 400° C, and a surface area of greater than or equal to 0.7 m2.

10. The item as claimed in claim 1 , wherein the item is a table or a worktop or a furniture unit.

11. The item as claimed in claim 1 , wherein the item is a worktop or furniture unit.

12. The item as claimed in claim 1 , wherein, when the support is in the first position, the element(s) situated on the support lie facing the lower face of the sheet at a distance of under 1 cm from the sheet and, when the support is in the second position, at least one of the ends of the support, or even the entirety of the support, lies at a distance of at least 10 cm.

13. The item as claimed in claim 1 , wherein, when the support is in the first position, the element(s) situated on the support lie facing the lower face of the sheet at a distance of less than 5 mm from the sheet and, when the support is in the second position, at least one of the ends of the support, or even the entirety of the support, lies at a distance of at least 15 cm.

14. The item as claimed in claim 1 , wherein, when the support is in the second position, at least one of the ends of the support, or even the entirety of the support, lies at a distance of at least 50 cm.

15. The item as claimed in claim 1 , wherein the movement of the support is about an axis of rotation, situated along an opposite edge to the edge intended to be moved away from the sheet, with an angle of at least at least 10° with respect to the first position of the support, or along guide rails or slides, where appropriate allowing a movement that is vertical and horizontal, for example approximately S-shaped.

16. The item as claimed in claim 1 , wherein the movement of the support is about an axis of rotation, situated along an opposite edge to the edge intended to be moved away from the sheet, with an angle of at least at least 30° with respect to the first position of the support, or along guide rails or slides, Where appropriate :allowing a movement that is vertical and horizontal, for example approximately S-shaped.

17. The item as claimed in claim 1 , wherein the movement of the support is about an axis of rotation, situated along an opposite edge to the edge intended to be moved away from the sheet, with an angle of at least at least 60°, with respect to the first position of the support, or along guide rails or slides, where appropriate allowing a movement that is vertical and horizontal, for example approximately S-shaped.

18. The item as claimed in claim 1 , wherein the glass ceramic sheet occupies more than 80% of the surface area of one face of said item, said sheet in particular resting on at least one casing or one or more support legs, without a seal in. between.

19. The item as claimed in claim 1 , wherein the glass ceramic sheet occupies more than 90% of the surface area of one face of said item, said sheet in particular resting on at least one casing or one or more support legs, without a seal in between.
