Claims
What I claim is:
1. A device for supporting and segregating articles for storage and
for handling comprising a relatively rigid sheet crenelated to
sawtooth wavular form to define a plurality of straight channels
and alternately interposed upstanding ridges arranged parallel to
each other and parallel to a flat zero axis plane lying midway
between the tops and bottoms of said ridges and channels and having
flat sidewalls uniformly inclined at approximately 90.degree. to
each other in such manner that a section taken through the sheet on
any plane perpendicular to the channels and to said zero axis plane
defines a configuration of like and uniform sawtooth wavelike form,
a flat uninterrupted perimetric flange integral with said sheet and
extending entirely around the same on said zero axis plane, and
integral walls joining the sidewalls to each other and to said
flange and closing the ends of said channels and said ridges above
and below the flange.
2. A device as defined in claim 1 including a plurality of narrow
straight-sided indentations defined by a plurality of pairs of
parallel flat walls extending downwardly from the crests of each
wavelike portion parallel to said section plane and each connecting
the sidewalls of one of the channels, corresponding walls of the
several indentations being coplanar and adapted to receive
removable partitions for bridging and dividing the channels.
Description
BACKGROUND OF THE INVENTION
In the storage and handling of unpackaged articles it is frequently
desirable to prevent unwanted relative motion and contact between
the articles and it is of course desirable that the articles be
compactly held to provide the greatest practical storage capacity,
and that a number of layers of the articles can be stacked in an
interkeyed relationship which prevents unwanted displacement during
transport and handling.
The primary objects of the present invention can be summarized as
the provision of an improved traylike receptacle-pallet which
accomplishes the objectives above indicated in a convenient and
economical manner, which provides effective protection for and
accommodates a wide variety of differently shaped articles, which
occupies a minimum of space when in use, and which when not in use
can be stacked and stored in a small space. Additional objects are
to provide such a device which is light in weight, readily
cleanable, does not absorb oil, water or dirt, does not damage fine
surfaces, and which is readily adapted to be handled in stacks on
standard loading pallets, mounted in racks or stood on a floor or
other support.
Other objects and advantages will become apparent upon
consideration of the present disclosure in its entirety.
BRIEF DESCRIPTION OF THE FIGURES OF DRAWING
FIG. 1 is a perspective view of a receptacle-pallet constructed in
accordance with the present invention;
FIG. 2 is an elevational view showing a plurality of the
receptacle-pallets in use and supported on a conventional pallet;
and
FIGS. 3 and 4 are sectional detailed views on a larger scale taken
respectively as indicated by the lines and arrows III-III and IV-IV
of FIG. 1.
DETAILED DESCRIPTION OF PREFERRED FORM OF THE INVENTION
Referring now to the drawing, my preferred receptacle-pallet is
constructed of a single rectangular sheet of rigid plastic such as
linear polyethylene, contoured, as by the vacuum forming process,
to provide a flat coplanar rim section 10 bounding a
work-supporting section consisting of wavular walls 14 and 15
defining a plurality of work-receiving channels 12 lying parallel
to each other in a transverse series along the rectangular plane
defined by the rim 10. The walls 14 and 15 converge upwardly and
downwardly to crests 16 located above the rim 10 and troughs 17
located below the rim. The upper surfaces of the troughs define the
receptacle portions, while the undersides of the crests of an
overlying unit act to position and isolate articles as W positioned
in the troughs of the subjacent unit.
The ends of the upwardly projecting wavular portions are closed by
wall sections 20 integral with the sheet and similar integral end
wall portions 21 close the ends of the troughs in the areas lying
below the rim 10.
Each crest portion is provided with a plurality of transverse
flat-walled indentations 22, the walls 24 defining such
indentations extending perpendicularly both to the channels and to
the generally flat plane of arrangement or zero axis plane of the
channels. The depression sidewalls 24 provide rigid connections
between the sidewalls 14, 15 for a substantial distance downwardly
from the crests, and such depressions are preferably aligned
longitudinally, so that when desired partitioning elements 26 can
be placed in the slots defined by such indentations, bridging the
trough area, to isolate articles located in the bridged trough, or
to support articles which are short axially.
Articles located in and projecting upwardly from the troughs to
positions above the crests are adapted to extend into the spaces
beneath and between the corresponding walls 14, 15 of a similar
unit placed over the stored articles and displaced laterally
one-half wavelength, as shown in FIG. 2. As also shown in the
latter view, a bottom unit A shown resting upon a conventional
pallet 25, contains articles W which project upwardly in the manner
indicated into the spaces between the wavular walls of the
superposed unit B, which similarly carries workpieces which support
a third unit C laterally displaced to the right from the unit B so
as to directly overlie the Unit A. Of course, any number of such
units may be stacked in this manner which the workpieces can
properly support.
This Detailed Description of Preferred Form of the Invention, and
the accompanying drawings, have been furnished in compliance with
the statutory requirement to set forth the best mode contemplated
by the inventor of carrying out the invention. The prior portions
consisting of the Abstract of the Disclosure and the Background of
the Invention are furnished without prejudice in an effort to
comply with administrative requirements of the Patent Office.
