[0001] The present invention relates to a shelf system composed of horizontal shelf members
in the form of plate members of wood or a similar material and vertical partition
and support members.
[0002] Conventional, unsupported racks and shelf systems most often comprise bottom, top
and end members which are permanently joined in a fixed frame structure, in which
the horizontal shelf members are placed in normally detachable shelf carriers secured
to the end members or to vertical partition walls in the frame structure. Such racks
or shelf systems are therefore i.a. comparatively space-demanding during transportation
and storing.
[0003] In conventional wall or suspension shelf systems the horizontal shelf members are
most often secured in movable positions to a structural member usually composed of
vertical rail members secured to a wall, which does, to a considerable degree, make
the erecting difficult.
[0004] The object of the invention is to provide a shelf system which may be erected as
a freestanding, self-supporting structure consisting of simple construction elements,
which require very little space, and having very simple joints, whereby the erection
becomes considerably easier than in case of conventional wall or suspension shelves,
the structure having at the same time a rigidity and stability which allows the erecting
of comparatively big shelf systems.
[0005] To meet this object, the shelf system according to the invention is characterized
in that the vertical partition and support members are designed as L-shaped angular
members comprising a partition member having upper and lower edges for abutting adjacent
shelf members and a backside member perpendicular to the partition member and having
upper and lower edges projecting a predetermined distance beyond the upper and lower
edges of the partition members for connection with said adjacent shelf members by
fitting the upper and lower edges of the backside member into grooves extending in
the shelf members parallel to front and/or rear edge surfaces thereof and having substantially
the same depth as said predetermined distance.
[0006] Shelf systems according to the invention may thus be supplied as knock-down systems
consisting of the horizontal shelf members and the vertical partition and support
members, from which shelf systems in various embodiments may be erected solely by
joining the shelf members and the vertical partition and support members by said fitting
of the upper and lower edges of the backside members of the L-shaped partition and
support members into the grooves extending along the rear edges of the shelf members.
It has turned out that a satisfactory rigidity and stability may be obtained without
the use of adhesive joints or the like, a fact which gives flexible possibilities
of rebuilding the shelf system according to demand.
[0007] The shelf members may be manufactured and delivered in varying lengths for the erection
of shelf systems of differing size, just as the partition and support members may
be supplied in different heights in order to make varying spacing of the shelves possible.
[0008] Advantageous embodiments and features of the shelf system according to the invention
are defined in dependent claims 2-12.
[0009] In a preferred embodiment the shelf members and the partition members are designed
with the same cross-sectional profile with grooves at both sides of the plate.
[0010] This provides an advantageous and rational production by a manufacturing method which
according to the invention is characterized in that shelf members and partition members
are cut in lengths from elongate plate pieces having said cross-sectional profile,
following which the partition members are joined with backside members.
[0011] The invention will now be explained in detail in the following with reference to
the drawing, in which
Fig. 1 illustrates a non-limiting example of a shelf system according to the invention,
Fig. 2 shows an embodiment of a horizontal shelf member,
Figs 3 and 4 two alternative embodiments of the vertical partition and support members,
Fig. 5 illustrates the joining of a shelf member as shown in Fig. 2 with a vertical
partition and support member as shown in Fig. 2,
Fig. 6 shows a modification of a partition and support member as shown i Fig. 3, and
Fig. 7 shows a shelf system according to the invention designed as a book tower.
[0012] The detached, self-supporting shelf system of Fig. 1 is generally composed of through-going
horizontal shelf members 1 and vertical partition and support members 2 placed between
superjacent shelf members. The shelf system may at the top be provided with a special
top plate member 3, just as the vertical support members at the ends of the shelf
system may be designed as special end members 4. The shelf system may be erected on
a conventional base member 5, which does not form part of the present invention.
[0013] In the embodiment shown in Fig. 2, the shelf member 1 is made from wood or a similar
material, for instance a hard fibre plate product, of a conventional oblong, rectangular
shape with a front edge 6 and a rear edge 7. Parallel with and at a short distance
from the rear edge 6, the shelf member 1 is throughout its length provided with a
groove 8 of rectangular or square cross-section for receiving a backside member of
the partition and support member 2 shown in Fig. 3.
[0014] As shown in Fig. 2, grooves 8 may be provided in both sides of the shelf, but in
particular in case of a top plate member 3, as shown in Fig. 1, it may for aesthetic
reasons be preferred only to provide grooves in the bottom side.
[0015] As shown in Fig. 3, the partition and support member 2 is designed as an L-shaped
angular member composed of a partition member 9 with upper and lower edge surfaces
10 and 11 for abutment against adjacent shelf members 1 and a backside member 12 perpendicular
to the partition member 9 and having upper and lower edge surfaces 13 and 14 projecting
beyond the upper and lower edge surfaces 10 and 11 of the partition member by a predetermined
distance corresponding to the depth of the groove 8 in the shelf member 1. The backside
member 12 has a thickness which corresponds to the width of the groove 8 in the shelf
member 1, such that the partition and support member 2, as shown in Fig. 5, may be
connected with the shelf member 1 by fitting the upper or lower edge 13 or 14 of the
backside member 12 into the groove 8 on the upper side or the bottom side of the adjacent
shelf member 1.
[0016] When the backside member 12 has a thickness of 3 mm, suitable dimensions of the groove
8 may be 3 x 3 mm, just as the distance of the groove 8 from the rear edge surface
7 of the shelf member 1 may conveniently be 3 mm.
[0017] In the embodiment shown in Fig. 3, the partition and support member 2 is, like the
shelf member 1, made from wood or a similar material, and the backside member 12 is
permanently connected with the partition member 9 by a side edge 16 thereof being
glued into a vertical groove 17 parallel to the rear edge surface 18 of the partition
member 9.
[0018] The vertical grooves 17 are preferably provided in both sides of the partition member
9, which, from a manufacturing and mounting point of view, has the considerable advantage
that shelf members 1 and partition members 9 may be manufactured with the same cross-sectional
profile. Thereby, a shelf system may according to the invention be manufactured from
only two components, namely a plate member provided with a groove in both sides, from
which shelf members 1 and partition members 9 may be cut in variable lengths, and
a thinner plate member for the manufacture of the backside members 12.
[0019] The very simple construction of the shelf system with the shelf members 1, as shown
in Fig. 2, and the particular L-shaped partition and support members 2, as shown in
Fig. 3, has turned out to impart a particularly good rigidity and stability to the
shelf structure, in which there is no need for glued joints between the shelf members
and the partition and support members.
[0020] If an improved safety as to positioning is desired in respect of the partition and
support members 2 relative to the shelf members 1, an engaging joint may be provided
for instance in the vicinity of the front edge surface 19 of the partition member
9, for instance a mortise or dowel joint as shown by a pin or a dowel hole 20 in Fig.
3.
[0021] By the alternative embodiment shown in Fig. 4, a partition and support member 15
may be manufactured in one piece as an angled metal sheet member 21, for instance
with a thickness of 1.25 mm. Of course, the dimensions of the groove 8 in the shelf
members 1 have to be adapted accordingly. Corresponding to the upwards and downwards
projecting upper and lower edges 13, 14 of the backside member 12 in Fig. 3, the backside
member 22 of the metal sheet member 21 in Fig. 4 is provided with upwards and downwards
extending edge protrusions 22a at the upper edge and the bottom edge, whereas at its
front edge the partition member 23 is reinforced by e.g. a square bracing profile
23a.
[0022] Fig. 6 shows an alternative embodiment of the partition and support member, in which
the backside member 12a is permanently connected with the partition member 9a by glueing
in a rebate 24 at the rear edge 18a of the plate member 9a.
[0023] In Fig. 7 the shelf system according to the invention is shown in a particular embodiment
as a book tower with a substantially square base. The shelf members 25 have a square
outer outline and a groove 26, which extends circumferentially in a substantially
square form and has groove sections 26a extending in parallel with exterior edges
27 of the shelf member 25' in a distance corresponding to the width of the partition
members 9 of the partition and support members 2, which may be manufactured as shown
in Fig. 3, or alternatively as shown in Fig. 4.
