[0001] The present invention relates to a bookcase which can be expanded in the longitudinal
direction.
[0002] It is known in the technical sector relating to the manufacture of furniture and
the like that there exists the need to adapt said furniture so that it is able to
occupy a larger or smaller amount of space depending on the actual use made of it
and depending on the space which is available for its positioning, which space may
vary over time.
[0003] An example of this need is provided by bookcases which are normally designed with
dimensions for the specific width which is available at the time of assembly and which
pose a problem should their overall dimensions need to be subsequently varied in order
to make them longer or shorter.
[0004] The technical problem which is posed, therefore, is that of providing a bookcase
which is able to vary its lengthwise dimensions in a simple and easy manner also so
that the end user is not obliged to call upon the assistance of specialized personnel.
[0005] Within the scope of this problem a further requirement is that the bookcase should
consist of modular elements which can be joined together and that the aesthetic appearance
of the bookcase should retain its unified nature also after lengthening thereof, so
as not to have unaesthetic additions which differ substantially from the design of
furniture.
[0006] These technical problems are solved according to the present invention by a bookcase
comprising a fixed body consisting of two shoulders, two cross-pieces, i.e. an upper
one and lower one, and at least one shelf arranged between said shoulders, there being
provided a sliding body formed by a shoulder, which has fixed to its opposite ends
a transverse surface provided with longitudinal guide means which are designed to
co-operate with corresponding rails which are fixed to the cross-pieces of the fixed
body, and by at least one shelf which is designed to perform a translatory movement
in both directions guided by said at least one shelf of the fixed body.
[0007] Further details may be obtained from the following description of a non-limiting

[0008] A bookcase according to the invention comprises essentially a fixed body 10 consisting
of two side shoulders 11 and two cross-pieces, i.e. an upper cross-piece 12 and lower
cross-piece 13, and a movable body 20 able to perform a sliding translatory movement
inside the fixed body 10, as will emerge in greater detail below.
[0009] The side shoulders 11 of the fixed body are in turn formed by two uprights 11a and
by a plurality of tubular cross-pieces 11b which connect the uprights together.
[0010] The upper cross-piece 12 and the lower cross-piece 13 have, fastened to them, two
guides in the form of an overturned "U" 12a which are arranged in the longitudinal
direction and which slidably support two slides connected to the movable body and
described below.
[0011] The fixed body 10 has, fitted to it, at least one shelf 14 with longitudinal side
edges 14a which are folded inwards so as to form a guide 14b for the shelves 30 connected
to the sliding body 20.
[0012] The sliding body 20 is in turn formed by a shoulder 21 which has connected, at its
opposite ends, two surfaces forming respectively an upper cross-piece 22 and a lower
cross-piece 23, forming as a whole a "C", the horizontal arms of which slide longitudinally
inside the fixed body 10.
[0013] The respective external surfaces of the two movable cross-pieces 22 and 23 have two
pairs of longitudinal projections 24 which have, fixed onto one of their surfaces,
a longitudinal slide 25 which travels on the guides 12a in the form of an overturned
"U" which are fixed to the body 10 of the bookcase.
[0014] Each shoulder 21 (Fig. 7) has, mounted on it, two metal strips 26 which are provided
with threaded holes 26a into which special fork members 27 are fixed, said members
being designed to receive the transverse edge of each shelf 30 so as to support it
and keep it perpendicular to the shoulder 21, while making the structure rigid.
[0015] All the shelves 14 (Fig. 6) have a transverse edge shaped with projecting frets 14c
which form brackets for resting on the tubular cross-pieces 11b, said frets defining
corresponding seats 14d.
[0016] The particular fretted shape allows two consecutive and coplanar shelves 30 to be
joined together in the longitudinal direction without interrupting the continuity
of the surface.
[0017] The upper front part of the bookcase (Fig. 9) also has, fitted to it, linear illuminating
bodies 50 which may be extended in the longitudinal direction by means of suitable
joining and support elements in the form of a "T", 51, or "L" ,52, thus allowing the
extension of the illuminating part to be adapted to the extension of the bookcase
without unaesthetic interruptions.
[0018] It is also envisaged that the external surface of said sliding body is provided with
a concealed handle for gripping and pulling out the body itself.
[0019] It is therefore obvious how the bookcase according to the invention may be lengthened
laterally so as to adapt the bookcase to the specific requirements and how the modularity
of the structure allows the overall extension to be multiplied retaining in this case
the possibility of extension for only one or both the opposite end modules.
