Description

FIELD OF THE INVENTION

[0001] The invention relates to shelving devices, also named gondola, comprising at least one moveable bottom shelf for displaying articles.

BACKGROUND ART

[0002] Shelving devices, also named gondola, comprising a plurality of shelves for displaying articles are well known. Said shelving devices generally comprise a base, a plurality of vertical columns which extend from the base and a plurality of shelves, also named sales shelves, each mounted on two successive vertical columns.

[0003] Many articles are resting on the shelves so that the latter have to bear the weight of these articles, which weight can be heavy. The shelves have thus to be substantially rigid and must tolerate a shear stress which is high.

[0004] The shelves are generally each formed by a metal plate which is configured to be loaded with many articles.

[0005] Most of shelves are arranged on the shelving device such that they are easily accessible for a user that stocks up again said shelves.

[0006] However, some shelves, in particular the lowermost shelf mounted on the shelving device, are not so easy to access and the user has to bend down or to crouch for facing such a shelf and then to stretch out its arm to reach the rear of said shelf in order to put or to catch articles.

[0007] The position of the user is therefore particularly uncomfortable.

[0008] Others shelving devices have already known, which comprise moveable bottom shelves having generally an inserted position for displaying articles placed thereon and a deployed position for restocking.

[0009] Said moveable shelves are arranged like conventional drawers. Namely, they comprise a casing having slide elements which cooperate with guiding rails fixed on the base or on lateral panels that comprises the shelving device.

SUMMARY OF THE INVENTION

[0010] The invention is directed to a shelving device for displaying articles, comprising at least a moveable bottom shelf, which shelf is configured to be convenient and easily accessible for a user to restock and which is also simple, economic and easy to manufacture.

[0011] The invention accordingly provides a shelving device for displaying articles, comprising a base, at least one moveable bottom shelf which is mounted on said base and a back frame extending from said base and configured to receive at least one fixed shelf overhanging said base, said at least one moveable bottom shelf having an inserted position in which said at least one moveable bottom shelf is introduced into a receiving space defined at least by said base and a deployed position in which said at least one moveable bottom shelf is at least partially remote to said receiving space, characterized in that said at least one moveable bottom shelf comprises a support plate configured to display articles and a moving system configured to displace said support plate between said inserted and deployed positions, said moving system comprising at least one carrier on which said support plate rests, at least one mounting interface mounted on said base and at least one slide element sandwiched between and attached to both said at least one carrier and said at least one mounting interface; said at least one carrier, said at least one mounting interface and said at least one slide element being configured to allow the displacement of said at least one carrier and of said support plate which rests on said at least one carrier relative to said at least one mounting interface and to said base on which said at least one mounting interface is mounted.

[0012] The shelving device according to the invention is very convenient in that the at least one slide element has only the functions of guiding and sliding of the moveable bottom shelf and in that the at least one carrier has the function of carrying the heavy weight of the articles resting on the support plate. In other words, the at least one slide element does not carry the weight of the support plate.

[0013] The moving system of the moveable bottom shelf of the shelving device according to the invention thus allows the displacement of the moveable bottom shelf between the inserted and deployed positions in order for instance to restock the support plate in a safe manner, while being particularly simple, economic and easy to manufacture.
