Abstract

The comfort device (10) includes a table (12) including a plate (22) and attachment unit (14, 16) including: a lateral fixed support (46), attached to a vertical wall (20), including a first connecting portion by sliding, an attachment member (52) secured to the plate (22), including a second connecting portion by sliding, mating the first, and unit retractable unit for blocking the attachment member on the lateral fixed support, active at the end of a predefined travel of the first connecting portion on the second connecting portion. These blocking units are movable between a blocking position in which the first and second connecting portions are secured to each other, and a release position in which the first and second connecting portions are free to move relatively to each other.

Claims

1. A comfort device, including a table comprising a plate and attachment elements for attaching the table to a structural portion of a compartment, wherein the attachment elements include:

a lateral fixed support, intended to be attached to a vertical wall of the structural portion of the compartment, comprising a first connecting portion by sliding,

an attachment member secured to the plate of the table, comprising a second connecting portion by sliding, mating the first connecting portion by sliding,

retractable blocking elements for blocking the attachment member on the lateral fixed support, the retractable blocking elements being active when the attachment member is added onto the lateral fixed support at the end of a predefined travel from the first connecting portion by sliding relatively to the second connecting portion by sliding, these retractable blocking elements being movable between a blocking position in which the first connecting portion by sliding and the second connecting portion by sliding are secured to each other, and a release position in which the first connecting portion by sliding and the second connecting portion by sliding are free to move relatively to each other,

and in that one of the first connecting portion by sliding and the second connecting portion by sliding is formed by a rail, extending in a vertical direction, having a trapezoidal section in a horizontal plane, and the other one of the first connecting portion by sliding and second connecting portion by sliding is formed by an elongated housing mating said rail, wherein the rail may slide in the vertical direction.

2. The comfort device according to claim 1, wherein:

the rail extends in the vertical direction between a first end, intended to be presented first upon inserting the rail into the housing, as far as a second end, and has a width, in a transverse direction perpendicular to the vertical direction, which increases from the first end as far as the second end, and

the housing extends in the vertical direction from a lower mouth, and has a width, in the transverse direction, which decreases from this lower mouth.

3. The comfort device according to claim 1, wherein the table comprises a central leg secured to the plate, the attachment elements including a fixed support on the floor, intended to be attached to a floor wall of the structural portion of the compartment, intended to be connected to the central leg of the table, and comprising a maintaining element for maintaining this central leg.

4. The comfort device according to claim 3, wherein the fixed support on the floor includes a vertically protruding shape, having a peripheral edge comprising an upper rim extending from a portion of the peripheral edge, and the table leg includes a hollow lower area having an inner edge with a shape mating that of the peripheral edge, and having an inner abutment extending inwards, said inner abutment being intended to be inserted under the upper rim, this inner abutment being thus intended to cooperate with the upper rim for limiting vertical displacement upwards of the table leg.

5. The comfort device according to claim 4, wherein the upper rim extends horizontally from the peripheral edge by moving away from the lateral fixed support.

6. The comfort device according to claim 1, wherein the blocking elements include:

at least one male element borne by one from among the attachment member and the lateral fixed support, movable between a deployed position and a retracted position, and at least one first elastic member for returning the male element towards its deployed position,

at least one fixed female element, mating the male element, borne by the other one from among the attachment member and the lateral fixed support, each male element being found facing the corresponding female element when the attachment member is added onto the lateral fixed support at the end of the predefined travel of the first connecting portion by sliding with respect to the second connecting portion by sliding.

7. The comfort device according to claim 6, wherein the male element is able to cooperate with said other one from among the attachment member and the lateral fixed support, in order to be pushed towards its retracted position as long as the first connecting portion by sliding and second connecting portion by sliding cooperate with each other without being at the end of their travel.

8. The comfort device according to claim 6, including a displacement member for displacing the male element towards its retracted position, which may be actuated by an operator.

9. The comfort device according to claim 6, wherein each male element is formed by a hook borne by a rotating axis.

10. The comfort device according to claim 6, including a second elastic member laid out between the attachment member and the lateral fixed support, applying a separation force between the attachment member and the lateral fixed support in the vertical direction.

11. The comfort device according to claim 6, wherein each male element extends above its rotating axis in a vertical direction, and includes an elongated body connected to the rotating axis, and an extension extending and protruding therefrom and from the body, the extension being intended to cooperate with the corresponding female element, and the body being tilted with respect to the vertical direction, towards the female element.
