A household appliance for treating items comprising:
- a treating chamber comprising a top wall, a bottom wall, a rear wall, lateral walls, and an aperture for a closing door;
- a container slidingly arranged in the treating chamber and comprising a container section facing one of the lateral walls;
- and
- a supporting device arranged between the container section and the lateral wall and comprising at least a pair of rolling members including
- a first rolling member and a second rolling member both connected to the one lateral wall or to the container section and a rail connected to the container section or to the lateral wall, wherein the rail is configured to be received between the first and second rolling members and comprises
- a first rolling surface contacting the first rolling member,
- a second rolling surface contacting the second rolling member, and
- a central section comprised between the first rolling surface and the second rolling surface,
- wherein the supporting device allows reciprocal movement of the rail with respect to the first and second rolling members along a first direction (d1) and a reciprocal movement of the rail with respect to the first and second rolling members along a second direction (d2) that is opposite the first direction (d1), wherein the supporting device comprises a stop device arranged at the rail to define an end of stroke of the reciprocal movement of the rail along the first direction (d1),
- wherein the first direction (d1) is:
- the extraction direction of the rail with respect to the first and second rolling members when the first and second rolling members are both connected to the lateral wall and the rail is connected to the container section (22);
- or
- the extraction direction of the first and second rolling members with respect to the rail when the rail is connected to the lateral wall and the first and second rolling members are both connected to the container section;
- wherein the stop device comprises a stopping portion and an elastic portion, wherein the elastic portion enables the stopping portion to be moved to a stopping position and to a releasing position, wherein, in the stopping position, the stopping portion protrudes from the first rolling surface and abuts the first rolling member to define the end of stroke of the reciprocal movement of the rail with respect to the rolling members along the first direction (d1), and wherein, in the releasing position, the elastic portion collapses under the action of the first rolling member pushing the stopping portion towards the central section of the rail so that the first rolling member moves beyond the stopping portion when the reciprocal movement of the rail with respect to the rolling members is carried out along the second direction (d2).
