Description
BACKGROUND OF THE INVENTION
The use of various types of display fixtures in retail stores is
well known. Most of these fixtures are portable and consist of
stands or tables provided with racks or shelves. Examples of
various types of display racks and shelves are shown in U.S. Pat.
Nos. 2,230,374 and 3,127,020. In another type of adjustable shelf
bracket assembly illustrated in U.S. Pat. No. 3,080,980, upright
members are supported between a floor and ceiling and are adapted
to receive a plurality of shelf brackets for supporting
shelves.
Many present day stores cover a large area on a single floor. In
many cases ceilings are fairly high and floor to ceiling uprights
to support shelves would be impractical. Portable stands and tables
are commonly used but often leave much to be desired.
OBJECTS OF THE INVENTION
One of the objects of the present invention is to provide display
fixture units which are secured directly to the floor.
Another object of the invention is to provide floor display
fixtures which can be adapted for use on floors that are somewhat
uneven.
Another object of the invention is to provide floor display
fixtures which can be used in a long line in a relatively large
store area and are adapted to support shelves, dividers, drawers
and other display devices.

DESCRIPTION OF THE INVENTION
The invention in its broader aspects provides a floor display
fixture unit comprising one or more tubular upright members having
means for attaching display fixtures, one or more tubular floor
plugs disposed within a floor with the upper ends at floor level,
and means securing said upright members to said floor plugs.
Shelves, dividers, structures containing drawers and other display
devices are attached to said upright members.
In order to provide for attachment of various types of display
fixtures to the tubular upright members, the latter comprise slots
which are spaced vertically. Usually, the upright members are
either circular in cross section or rectangular and in either case
it is preferable to have the slots spaced not only vertically but
also laterally approximately 90.degree. apart.
In order to provide rigidity, the floor plugs are internally
tapered and the upright members are tapered at one end and inserted
into the tapered tubular floor plugs or they are secured to a
tapered tubular adapter which is inserted into a tapered tubular
floor plug. In either case, it is essential that there be a snug
fit between the internal surface of the floor plugs and the
external surface of the upright member or adapter which is inserted
into the floor plug.
Since most floors in large stores are made of concrete and the
surfaces are not always uniform or even, it is desirable to provide
means for securing the upright members to the floor plugs which is
adjustable to different heights. This can be accomplished by
providing external threads on the lower ends of the upright
members, placing an internally threaded lock nut on the threaded
portion of the upright member whereby the internal threads of the
locknut engage the external threads of the upright member and
providing internal threads in the floor plug or the adapter so that
the height of the upright member can be adjusted by turning said
member until the desired level has been attained, and then locking
it at this level by turning the locknut until it engages the top of
the internally threaded member which supports the upright
member.
It is also desirable that the floor plugs be adapted to receive a
cover at their upper ends. This can be provided by offsetting the
their end of the floor plug laterally and forming screw threads on
the vertical part of the inner surface of the vertical part of the
offset portion. The cover or floor plate can then be formed with
screw threads on its outer surface which are adapted to engage the
screw threads on the inner surface of the floor plug. A recess can
be provided in the top of the cover to permit the insertion of a
tool so that the cover can be turned and removed from the floor
plug.
According to one form of floor display fixture provided by the
invention, there is only one tubular upright member on which a
plurality of vertically spaced shelves are mounted, each of said
shelves having a center hole large enough to receive the upright
member and each being mounted on the upright member at the center
hole so that each shelf surrounds the upright member. In this
embodiment of the invention the shelves can also be made rotatable
in the manner hereinafter described.
In another embodiment of the invention the floor display fixture
comprises two units connected in the upper and lower portions by
parallel bar members and having panel members vertically disposed
between and connected to said bar members. This type of floor
display fixture is especially useful as a divider between two sales
areas.
In most cases the floor display fixtures will be employed in the
form of two or more tubular upright members supporting horizontally
disposed shelves, vertically disposed panels and horizontally
disposed structures containing drawers.
Referring to the drawings, in FIG. 1 the floor display fixture unit
shown comprises a tubular upright member 1 provided with slots 2
which are spaced vertically and are also spaced transversely from
other slots 3. Preferably there are four slots at each level spaced
laterally approximately 90.degree. apart. In the embodiment of the
invention shown in FIG. 1 the upright member 1 is round in cross
section but it can also have a square cross section in which case
there is preferably a series of slots spaced vertically on each
side of the square.
As shown in the lower part of FIG. 1 in order to construct the
floor display fixture unit and provide a suitable means for holding
said unit, a hole 4 is drilled in a concrete floor 5 or other
suitable supporting surface. The hole 4 preferably has a laterally
offset portion 6 adjacent the floor level. A floor plug 7 is
inserted into the hole 4. The inner wall 8 of the hole 4 is tapered
and the outer wall 9 of the floor plug 7 is also tapered so as to
provide a snug fit between the floor plug 7 and the wall 8 of the
hole 4. The upper end 10 of the floor plug 7 is flanged and is
adapted to fit into the space 6 in the floor 5 thereby providing a
fixed relationship between the floor plug 7 and the floor 5.
As shown in FIG. 4 the floor plug 7 is preferably threaded
internally near the upper part thereof at 11 so that a cover 12
having external threads 13 can be secured into the floor plug at
floor level. A recess 14 is provided in the upper part of the cover
12 to permit insertion of a screwdriver or other suitable tool for
the purpose of removing the cover when it is desired to construct a
floor display fixture unit.
According to a preferred form of the invention, a tubular adapter
15 is provided to secure the tubular upright member 1 to the floor
plug 7. The upper part 16 of the tubular adapter 15 is circular and
of uniform internal diameter. The lower part 17 is tapered and is
adapted to fit snugly against the inner wall of floor plug 7 when
the lower part 17 of adapter 15 is inserted into the floor plug.
The resultant pressfit or frictionfit affords rigidity but at the
same time makes it possible to remove the entire assembly by
pulling it upwardly.
As shown in FIGS. 1 and 3, the lower portion 18 of the upright
member 1 is threaded at 19 and the inner surface of the upper part
16 of adapter 15 is internally threaded at 20 so that the threads
19 can be engaged with the threads 20 thereby screwing the upright
member 1 to the adapter 15 which in turn is secured to the floor
plug 7 by inserting the lower portion 17 of adapter 15 into the
tapered tubular space 21. The height of the tubular upright member
1 can be adjusted by rotating said member. When the desired height
is attained the locknut 22 is rotated until it contacts the upper
surface 23 of the adapter member 15. The assembled relationship is
illustrated in FIG. 2.
In the form of the invention illustrated in FIG. 6 the upright
member 1 supports a series of shelves 24, 25 and 26 and a top shelf
27. These shelves can be made of wood, metal, plastic or any other
suitable self-supporting rigid material. One method of supporting
the shelves on the upright member 1 is shown in FIG. 9. Each shelf
in this case is supported by a plate 28 which is secured beneath
the shelf by screws or other suitable means, not shown, inserted
through holes 29. Each plate 28 has a central opening 30 which is
large enough so that it will receive the upright member 1. Each
shelf also has a collar 31 with an opening therethrough
corresponding to the opening 30. The upright member 1 is provided
with holes 32 on four sides with the opposite holes being aligned
so that a bar 33 can be inserted through said holes and is long
enough to project beyond the opposite sides of upright member 1.
Each of the shelves also has a central opening corresponding to the
opening 30 so that the shelves and their associated plate 28 and
collar 31 can be mounted on the upright member 1 at the desired
level and then held in place by inserting the bar 33 through the
holes 32 on said level. The top walls of recesses 33a and 33b
engage the bottom walls of openings 32, 32 thereby holding bar 33
in place. Alternatively, brackets 32a and 32b can be inserted into
openings 32 so that the bottom of collar 31 will rest on the top of
said brackets. In this type of structure, the shelves are also
capable of being rotated so long as there is sufficient clearance
between the outer walls of the tubular upright member 1 and the
sidewalls of the opening 30.
In FIG. 7 the upright members 1 are used to support a divider 34
and shelves 35 and 36 as well as a structure 37 having a drawer 38.
The shelves, divider and drawer structure can be mounted in any
suitable manner in the slots 2 provided in the tubular upright
member, e.g., by means of brackets 35a having hooklike members 2a
and 2b adapted to be inserted into slots 2.
In FIG. 8 the tubular upright members 1 are connected by parallel
bars 39 and 40 which are rectangular in cross section. This
connection can be made in the manner illustrated in FIG. 10 wherein
a bracket 41 is inserted in opening 2 in tubular upright member 1.
The external surface of the bracket 41 is of such size as to fit
snugly within the internal surface of the bar 39 and the bar and
bracket are secured together by screw 42. In the modification shown
in FIG. 10, the bracket 41a has transversely extending holes
adapted to receive bolt 42a which is inserted through the holes in
bar 39 and bracket 41a and held in place by nut 42b. Panels 43, 44
and 45 are secured between the bars 39 and 40 in any suitable
manner. These panels can be used for advertising purposes and the
entire structure can be used as an area divider.
The invention is useful especially in large stores having an
extensive unobstructed floor space. It will be recognized that some
modifications and variations may be made in the structures
described without departing from the invention.
