Description

FIELD OF THE INVENTION

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

BACKGROUND ART

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.
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.
The shelves are generally each formed by a metal plate which is configured to be loaded with many articles.
Most of shelves are arranged on the shelving device such that they are easily accessible for a user that stocks up again said shelves.
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.
The position of the user is therefore particularly uncomfortable.
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, see for example EP 0709049A . 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

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.
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, wherein 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, wherein said moving system comprises a plurality of wheels fixedly attached to said at least one carrier and configured to roll on a floor for displacing said carrier, characterised in that said base comprises at least one foot member having a receiving U-shaped portion and wherein said at least one mounting interface has a generally C-shaped comprising a main portion, a first and a second auxiliary portions and a first edge portion extending from said first auxiliary portion and configured to be introduced into said receiving U-shaped portion. 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.
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.
According to features preferred as being very simple, convenient and economical for embodying the shelving device according to the invention:

said at least one slide element comprises a first part fixedly attached to said at least one carrier and a second part slidable relative to said first part, attached to said at least one mounting interface and configured to be at least slightly vertically moveable relative to said at least one mounting interface and said at least one mounting interface is fixedly attached to said base; by virtue of which said at least one carrier on which rests said support plate is able to compensate the gradient of said floor on which said wheels are configured to roll;
said at least one mounting interface has a generally C-shaped comprising a main portion, a first and a second auxiliary portions and at least one vertical opening having for instance an oblong shape and being formed in said main portion;
said base comprises at least one slot formed in said receiving U-shaped portion and said at least one mounting interface comprises at least one tongue formed in said first edge portion, said at least one tongue being configured to be folded with respect to said first edge portion and introduced into said at least one slot;
said base comprises at least one foot member having a main body and said at least one mounting interface has a generally C-shaped comprising a main portion, a first and a second auxiliary portions and a second edge portion extending from said second auxiliary portion and configured to come into abutment against said main body;
said at least one carrier has a U-shaped comprising a bottom portion, a first and a second lateral portions and at least one bearing portion extending from at least one of said first and second lateral portions, and said support plate rests on said at least one bearing portion;
said support plate is welded to said at least one bearing portion;
said at least one moveable shelf comprises at least one bearing member distinct to said support plate, said at least one bearing member is attached to said at least one carrier and said support plate rests on said at least one bearing member;
said at least one moveable shelf comprises at least one rigid element fixedly attached to said support plate and said carrier comprises at least one cut-out in which said at least one rigid element is configured to be inserted;
said base comprises two foot members spaced apart and said moving system comprises two carriers, two mounting interfaces each fixedly attached to a respective foot member and two slide elements each attached to both a respective carrier and a respective mounting interface;
the shelving device comprises a plinth and said at least one carrier comprises a front wall on which said plinth is configured to be fastened;
the shelving device comprises at least one fixed shelf which is mounted on said back frame and which overhangs said base and said at least one moveable bottom shelf at least in its inserted position; and/or
said back frame comprises at least two vertical columns extending from said base and a back panel also extending from said base and disposed between said at least two vertical columns, said at least one fixed shelf being fixed to said at least two vertical columns.

The fixed shelves 6 are thus configured to be hung to the two vertical columns 4 thanks to the hooks of the consoles 24, hooks which are configured to be introduced into the respective first openings 16 formed in the front face 14 of the vertical columns 4.
The fixed shelves 6 are thus mounted on the back frame 3 so that they overhang the base 2.
The shelving device 1 further comprises the bottom moveable shelf 7 which is here located at the bottom of the shelving device 1. The fixed shelves 6 further overhang the moveable shelf 7.
The bottom moveable shelf 7 is configured to admit an inserted position in which the bottom moveable shelf 7 is close to the back frame 3 (Figures 1 and 3 to 5) and a deployed position in which the bottom moveable shelf 7 is remote to the back frame 3 (Figures 2 and 6).
