[0001] The present invention relates to a backing wall structure mainly for sales or exhibition
halls for active electrical or electronic appliances, in particular for sound or picture
reproduction. Such apparatuses may require certain cable connections for current and
signal supply, and whenever a plurality of such apparatuses is placed in front of
a backing wall it is a natural desire that these required cables can be drawn as hidden
as possible behind the wall structure.
[0002] This requirement already has resulted in the development of special wall structures
which comprise both vertical carrier posts for intermediate carrier shelves for the
apparatuses and intermediate wall panels, which allow for a cable connection just
behind the single apparatus units, but otherwise conceal the cables, see in particular
WO 95/26150.
[0003] However, in the wall systems known so far there are still some drawbacks, partly
in that the wall panels filling out the space between the posts should be designed
and fixed so as to be strong enough to resist local pressure impacts, and partly in
that they should be provided with throughlet holes or slots for the cables in such
a manner that these holes or slots will be visible at places in which they are not
visually covered by an apparatus unit right in front thereof. The requirement as to
a good fixation is not too compatible with another desired property, viz. that the
panel plates should preferably be easily de- and remountable for enabling reorganizations
of the cable connections and the cable arrangement behind the panel wall.
[0004] With the present invention it has been realized that it is possible to widely improve
these systems in a very simple manner, namely in that the panel plates, at their top
edges, are suspended in a pivotable manner and extend downwardly therefrom to a bottom
edge area located behind the top edge of the underlying panel plate. Hereby, more
of the said drawbacks are countered at the same time, in that
1) the panel plates will not need to be fixed otherwise than by a simple suspension
at their top edge, e.g. by a simple hooking up of a rearwardly bent over top edge
area onto a carrier rod or only onto two opposed, lateral projections on the adjacent
carrier posts;
2) the panel plates should not be designed with any particular strength, since by
a local impression they can pivot freely rearwardly, i.e. without having to resist
the impression;
3) the throughlet slots for the cables can be established according to requirements
just by a slight rearward pivoting of the relevant panel plates, whereby the slots
will be formed behind the top edges of the underlying panel plates and thus be invisible
from the front side;
4) throughlet slots or holes will not appear at such places where an apparatus unit
is not present in front thereof; and
5) the panel plates according to item 1) may be readily detachable from their support,
such that at any place they can easily be removed and remounted in connection with
desired rearrangements of the cables and the connections behind the panel wall.
[0005] As the strength requirements of the panel plates are very modest, these plates may
be designed as simple and inexpensive units of any suitable material, and they may
in a realistic manner be produced and stocked in many different variants, e.g. with
respect to structure or colour.
[0006] In the following the invention is desctibed in more detail with reference to the
drawing, in which:
Fig. 1 is a perspective fractional view of a backing wall structure according to the
invention;
Fig. 2 is and end view thereof;
Fig. 3 is an end view of a corresponding, free standing wall structure; and
Fig. 4 is a perspective view of a modified panel plate.
[0007] The structure shown in Fig 1 comprises a row of vertical post beams 2 with holes
4 usable in a conventional manner for the mounting of carrier brackets for shelves
6 in desired levels. According to the invention, there is at either side of the posts
2 welded a number of interflushing, horizontal carrier pins 8. The posts 2 are fixed
to a stable wall by means of length adjustable fixtures 10.
[0008] Between the posts 2 a number of filler plates 12 is provided, freely suspended on
the respective pins 8, e.g. in that the plates as made in metal or plastic having
an upper rearwardly bent-over edge portion 14 to be hooked onto the pins 8. The filler
or panel plates 12 have a height which is slightly bigger than the vertical distance
between the pins 8, whereby the plates, as shown, may extend obliquely downwardly
and inwardly to a bottom edge area right behind the top of the underlying plate. Thus,
each individual plate 12 will be free to pivot rearwardly about its top edge, and
for avoiding rattling, small shock absorbing elements 16 are mounted at the overlapping
areas. The presence of these elements may give rise to a narrow, vertically open slot
between the lower end of a plate 12 and the rear of the bent-over top portion 14 of
the underlying plate, but in general this slot will not be visible from outside.
[0009] The same will apply if this slot is made somewhat still broader, viz. if one or more
cables 18 as shown in Fig. 2 are let out from the space behind the wall to an apparatus
unit standing on a shelf 6 in front of this plate wall. It will be appreciated that
such cables may be lead out anywhere in the wall system without the associated, slightly
broader slot opening being visible from outside.
[0010] The plates 12 are readily unhooked from the pins 8, such that whenever and whereever
it is desired, larger area portions of the wall may be uncovered, thus making the
areas freely accessible for reorganization of the rear cables and connectors. The
complete wall structure is easily reestablished by simple rehooking of the plates
12.
[0011] Fig. 3 shows a structure, in which the carrier posts have a depth dimension large
enough to enable a free standing mounting for presentation of shelf carried apparatus
units at both sides, supported by floor engaging foot portions 20. The resulting wall
thickness is large enough to make space for the inwardly pivotable panel plates 12.
[0012] For the invention it is not a condition that the plates 12 should be uniform, as
they may vary with respect to both look and size. In that connection it may be desirable,
optionally, to use carrier posts having holes 4 also in the lateral sides, as the
pins 8 may then be mounted on carrier brackets for engaging the holes for adaptation
to different modular heights of the plates 12. Another possibility, though little
attractive from an aestethical point of view, will be to use pin carrying brackets
for mounting in the holes 4 in the front side of the posts.
[0013] As shown in Fig. 4, it may be a preferred possibility that the plates 12 are made
with a rear recess 22 along their bent-over top edges, either - as shown - by way
of cutting or by a sharper bending over than at the side portions cooperating with
the pins 8. Hereby permanent slots will be formed which, however, will not generally
be visible, and which enable at least thinner cables to be drawn through without the
cables holding the overlying plate swung rearwardly.
[0014] Even though it is most advantageous to arrange for the plates to be inwardly pivotable
at their lower end, the invention will nevertheless comprise a construction in which
the plates are outwardly pivotable. If the plates are arrestable or resiliently biased
they may even be hinged at their lower edges, thus pointing upwardly from the pins
8 or from other suitable hinge means.
[0015] The pivot plates 12 themselves may be used for independent purposes at desired places
of the wall, inasfar as they are easily workable for special purposes, e.g. with mounting
holes for instruments or lighting units or with holding means for CD cassettes.
