Description
The present invention relates generally to cascade shelving of the
general type which is employed in such establishments as stationary
stores, drug stores, book stores, and discount stores and also in
similar places where magazines, children's books, paper backs,
periodicals, and the like are displayed and sold. More
particularly, the invention is concerned with knockdown display
shelving of the cascade type wherein different cascade arrangements
may be selectively erected at a given sales location or
establishment in order to accommodate different floor areas, the
erection being manually performed without the use of fastening
devices such as nails or screws, and without the aid of ordinary or
special tools.
Cascade shelving of the type under consideration is usually
prefabricated in its entirety in various sizes, i.e., length, so as
to accommodate the requirements of various stores, the proper size
then being sold on order. This requires that the manufacturer of
the shelving either maintain a large inventory of varying size
shelving or correlate the shelving manufacturing or assembling
operations with the requirements of the market or, in other words,
that the manufacturer manufacture to order the shelving to be sold.
It occasionally happens that where a particularly large shelving
unit is required by a given establishment, entrance space dictates
that the shelving must be finally assembled on the premises,
thereby necessitating the services of a skilled workman to perform
the assembly work.
The present invention is designed to overcome the above-noted
limitation that is attendant upon the manufacture and sale of
conventional cascade shelving and, toward this end, the invention
contemplates the provision of a novel form of knockdown cascade
shelving assembly embodying the usual cascade units, end pieces and
medial dividers, the various parts being separately pre-formed and
having interlocking facilities so that they may be assembled in
various ways to provide unit shelving lengths which are arranged in
end-to-end fashion, thus establishing a cascade shelving assembly,
the over-all length of which is a multiple of such unit length.
According to the invention, it is contemplated that each unit of
shelving length (for example, 4 feet) shall embody a set of cascade
units, preferably a two or three tier set as is commonly the
practice with such display shelving, although a greater number of
such tiers in a single set may be employed if desired. Regardless
of the number of cascade units in each set, shelving of one unit
length will embody two end pieces and a set of cascade units with
no medial divider. Shelving of two unit lengths will embody two end
pieces, two sets of cascade units, and one medial divider. Each
additional unit length of shelving will employ an additional set of
cascade units and an additional divider unit. The aforementioned
interlocking facilities enable the shelving assembly to be quickly
and easily erected directly at the display or sales location
without the use of tools, it being necessary merely to hook the
cascade units in place on the adjacent end pieces or dividers, as
the case may be, and upon release of the thus hooked parts, the
force of gravity causes the parts to lock rigidly together to form
an assembly, the stability of which is increased as each unit of
display load is applied thereto. If, at any time, it is decided
that an additional unit length of cascade shelving shall be added
to an existing shelving assembly, it is merely necessary to
uncouple one end piece from its associated cascade units,
substitute a medial divider therefor, attach an additional set of
cascade units to the medial divider, and replace the uncoupled end
piece to the added cascade units.
An additional and equally important limitation that is attendant
upon the construction and marketing of conventional cascade type
shelving resides in the relatively large packaging volume which is
involved for each shelving assembly, thus greatly limiting the
number of paperboard cartons which can be transported in a truck or
railway car for shipment purposes. According to the present
invention, because the shelving assembly is possessed of knockdown
features, and also because all of the components which comprise the
same are relatively flat, i.e., possessed of small transverse
width, it is possible to stack the components together in a
relatively small space and enclose the stacked components in a
relatively small paperboard carton, the dimensional characteristics
of any given packaged shelving assembly being such that the stacked
components thereof consume something less than one-quarter of the
space which is required in packaging a conventional shelving
assembly having the same capacity but without the particular
knockdown feature of the present invention.
The provision of knockdown cascade type shelving such as is briefly
outlined above and possessing the stated advantages, constitutes
the principal object of the present invention.
Other ancillary advantages of the invention are the provision of a
shelving assembly which is of lightweight construction, is capable
of being manufactured at a low cost, is rugged and durable and,
therefore, will withstand rough usage without becoming damaged, is
extremely stable when erected despite the absence of nails and
other fastening devices, and is attractive in its general or
over-all appearance and pleasing in its design.
Other objects and advantages of the invention, not at this time
enumerated, will readily suggest themselves as the nature of the
invention is better understood from a consideration of the
following detailed description.
The invention consists in the several novel features which are
hereinafter described and are more particularly defined by the
claims at the conclusion hereof.
In the accompanying two sheets of drawings forming a part of this
specification, one illustrative embodiment of the invention is
shown.
In these drawings:
FIG. 1 is a diagonal front perspective view of a two-unit length of
cascade shelving embodying the invention and in which each unit
length embodies a three-tier set of cascade units;
FIG. 2 is a side elevational view of the shelving of FIG. 2 with
certain parts broken away in order more clearly to reveal the
nature of the invention;
FIG. 3 is an enlarged exploded view of certain parts of the
shelving of FIGS. 1 and 2;
FIG. 3a is an enlarged fragmentary sectional view taken on the
vertical line 3a--3a of FIG. 3;
FIG. 4 is an enlarged fragmentary sectional view taken on the line
4--4 of FIG. 1;
FIG. 5 is an enlarged sectional view taken on the line 5--5 of FIG.
2; and
FIG. 6 is a front perspective view of a single unit length of
shelving embodying the invention.
Referring now to the drawings in detail and in particular to FIG.
1, an exemplary all-wood cascade shelving assembly embodying the
principles of the present invention is designated in its entirety
by the reference numeral 10. The assembly which has been selected
for illustration herein is considered to be of two-unit length
wherein each unit length is comprised of two wall-forming side
pieces with an intervening set of cascade units or trays which are
arranged in three tiers. The term "side pieces" as employed herein
is a relative term in that it relates to the intervening cascade
units, but since the disclosure of FIG. 1 is concerned with a
two-unit length of cascade shelving, the outside wall-forming "side
pieces" actually are end pieces, while the medial wall-forming
piece is a divider. Accordingly, the end pieces are designated by
the reference numerals 12 and 14, while the divider is designated
by the reference numeral 16. The three cascade units or trays of
each unit length are designated by the reference numerals 18, 20,
and 22, 18 being the upper cascade tier, 20 being the intermediate
cascade tier, and 22 being the lower cascade tier. The term "tier"
may be defined alternatively as either a row or set of objects, or
one object of such a set. Accordingly, for purposes of description
herein, it will be understood that the latter definition is
employed, there being two sets of cascade units with the units of
each set including upper, intermediate, and lower tiers, each tier
consisting of one individual cascade unit.
The shelving assembly 10 further includes two backboards, namely,
an upper backboard 24 and a lower but intermediately disposed
backboard 26. The lower back region of the shelving assembly 10 is
preferably open.
The three cascade units 18, 20, and 22 are substantially identical
in construction and design and, therefore, a description of one of
them will suffice for all. The cascade unit 22, as is conventional
with similar cascade constuctions, includes, in general, a series
of substantially vertical but slightly backward leaning slot-like
partitions or partition walls (see FIGS. 2 and 3) which are
supported on a zig-zag or stairlike bottom wall. Such a general
arrangement is preserved in the present shelving assembly, but in a
specific manner and for purposes that will be made clear
presently.
The details of the various cascase units are best illustrated in
FIGS. 2, 3 and 4, each unit consisting of a pair of side walls 32
and 34, between which there extends a relatively wide and thick
rear wall 35 and a relatively narrow and thick front wall 36.
Considering the cascade unit 22 in the positional relationship
which it assumes when operatively installed in the shelving
assembly 10, the rear wall extends vertically, while the front wall
36 leans backwards, which is to say it assumes an angle on the
order of approximately 10.degree. with respect to the vertical.
Also extending between the side walls 32 and 34 is a series of four
equally spaced partition walls 40. These partition walls are
parallel to one another and also to the front wall 36 so that they
also lean backwards at a small angle. Although four such partition
walls 40 are disclosed or illustrated herein, it will be understood
that a greater or a lesser number thereof may be employed if so
desired. Also unequal spacing between the partition walls 40 may be
resorted to in order to accommodate the grouping of magazines or
books of different thicknesses. Irrespective, however, of the
number and spacing of the partition walls 40, the essential
features of the invention are at all times preserved.
Still referring to FIGS. 2, 3 and 4 of the drawings, the various
partition walls 40, the back wall 35 and the front walls 36 of the
cascade unit 22 are disposed in progressively offset relationship
so as to provide an ascending series of walls, the lower edge of
each wall projecting forwardly from a bottom wall 42 which extends
at a right angle with respect to the partition wall or walls to
which it is attached, such bottom walls thus being inclined
rearwardly and downwardly at a small angle from a horizontal plane.
The forward edge of each bottom wall 42 is secured in edge-to-face
relationship to the medial region of the next adjacent forward
partition wall 40, while the rear edge of such bottom wall is
secured in edge-to-edge relationship to the lower edge of the next
adjacent rearward partition wall 40. The foremost bottom wall 42
which is designated with the suffix a is somewhat wider than the
other bottom walls 42 and is attached to the lower edge of the
front wall 36 in edge-to-edge relationship. The additional width of
the bottom wall 42a is provided so as to accommodate the
positioning of wider books or other literature at the front of the
cascade shelving assembly. As shown in FIG. 4, the rearmost
partition wall 40 has its upper horizontal edge bevelled at a sharp
angle and adhesively secured to the front face of the back wall 35
as indicated at 43.
As best shown in FIG. 4 of the drawings, the two side walls 32 and
34 of the cascade unit 22 are identical in size and configuration,
each such wall being in the form of a relatively narrow elongated
strip of wood of irregular contour having upturned front and rear
end portions 44 and 46 respectively. The side edges of the various
partition walls 40 and bottom walls 42 are secured in edge-to-face
relationship to the inside faces of the two side walls 32 and 34 in
the medial regions of the latter so that the lower edge regions of
such side walls project a slight distance below the various bottom
walls 42 exclusive of the bottom wall 42a. For a purpose that will
be set forth in detail presently, the lower edge of each side wall
32 and 34 is formed with a right angle notch or cut-out 48 adjacent
to the forward end thereof and immediately behind or rearwards of
the upturned end portion 44. Additionally, the upper horizontal
edge of the rear wall 35 is formed with a coextensive groove 50
(see FIG. 4) therealong, while the lower edge of such wall is
similarly formed with a coextensive groove 52. The function of
these two grooves 50 and 52 will be made clear subsequently.
Considering now the nature of the end pieces 12 and 14 of the
shelving assembly 10, and referring particularly to FIG. 1, these
two pieces are identical in outline but they are complementary to
each other in that the end piece 12 serves to support the left-hand
sides of one set of cascade units, while the end piece 14 serves to
support the right-hand sides of a second set of cascade units.
Where a single or unit length of shelving is concerned, it is
obvious that the medial divider 16 will be omitted and the two end
pieces 12 and 14 will support therebetween a single set of the
cascade units as shown in FIG. 2 and as will be described in
greater detail subsequently. Accordingly, each end piece 12 or 14,
as the case may be, is generally of flat E-shape configuration,
which is to say that it is provided with a vertical stem portion 54
from which there projects forwards a vertical series of three
generally horizontal webs 56. Preferably, but not necessarily, the
vertical distance between the lowermost and intermediate webs is
slightly greater than the vertical distance between the
intermediate web and the uppermost web, thus resulting in a similar
unequal vertical spacing between the corresponding cascade units
18, 20 and 22.
Fastened in any suitable manner to the inside face of each end
piece 12 or 14 is a series of three vertically spaced, ledge
forming, cascade unit supporting strips 60, (FIG. 3) each strip
being generally of divergent L-shape. Each strip 60 is provided
with a long forwardly and downwardly inclined leg 62 and a short
forwardly and upwardly inclined foot portion 64, thus imparting to
the strip the general outline or configuration of a hockey stick.
The strips 60 extend from points adjacent to the rear vertical
edges of the end pieces 12 and 14 and project forwardly into the
various horizontal webs 56 as clearly shown in FIG. 4. As shown in
FIG. 3a, each strip 60 is generally rectangular in transverse cross
section and is secured in face-to-face relationship with respect to
the end piece with which it is associated. The upper side edge of
each strip 60 is formed with a coextensive corner relief 66 (FIG.
3a) which, in combination with the inside face of the adjacent side
piece, establishes a seating channel for removable reception
therein of the lower edge region of one of the side walls 32 or 34
of an adjacent cascade unit 18, 20 or 22. It has previously been
stated that the lower edge of each side wall 32 and 34 projects
below the level of both the partition walls 40 and the bottom walls
42 and, thus, as clearly shown in FIG. 4, each side wall presents a
downwardly directed edge portion which is conformably shaped to the
contour of the sealing channel which is established by the relief
area 66, this downwardly directed edge portion being capable of
entering the channel in hook-like fashion, thus providing a tongue
and groove connection so that one side of the associated cascade
unit may be supported on the bottom wall of the channel.
As shown in FIGS. 3 and 5, the medial divider 16 is identical in
contour or outline to the end pieces 12 and 14, but since it is
obliged to support both sets of cascade units 18, 20, and 22 of the
two-unit lengths of the shelving assembly 10, it is provided with
cascade unit supporting strips 60 on opposite sides thereof, these
strips being symmetrically positioned in conformity with the
positioning of the corresponding cascade unit supporting strips 60
on the end pieces 12 and 14. The medial divider 16 cooperates with
the end piece 12 in supporting one three-tier set of cascade units
18, 20, and 22, and it cooperates with the end piece 14 in
supporting the other three-tier set of such cascade units. The
manner in which the side wall 34 of the cascade unit 20 of the
left-hand set of cascade units hooks into the channel 66 of its
associated cascade suuporting strip 60 on the medial divider 16,
and in which the side wall 32 of the cascade unit 20 of the
right-hand set of cascade units hooks into the adjacent supporting
strip 60 on the other side of the medial divider 16 is clearly
shown in FIG. 5 of the drawings.
From the above description, it will be apparent that when a given
cascade unit 18, 20, or 22 is seated on a pair of associated
supporting strips 60, the normal tendency for the cascade unit is
to slide forwardly and downwardly on the inclined portions of the
bottom walls of the channels 66. However, such sliding movement is
limited by reason of the upturned, inclined foot portions 64 which
register with the right angle notches or cut-outs 48 in the front
portions of the side walls 32 and 34. Thus, in effect, each side
wall of any one cascade unit rests in the crotch of a V-shaped
support where it possesses stable equilibrium under the influence
of the gravitational weight of the cascade unit and its load
considered as a whole.
Considering now the backboard structure for the shelving assembly
10, each unit length of shelving includes a five-piece composite
backboard assembly which is made up of the three rear walls 35 of
the three tiers of cascade units 18, 20, and 22, together with the
aforementioned upper and lower backboards 24 and 26. In the absence
of the two backboards 24 and 26, each unit length of the shelving
assembly would be quite stable, but there would be a see-through
void between the upper cascade unit 18 and the intermediate cascade
unit 20, as well as between the latter unit and the lower cascade
unit 22. The two backboards 24 and 26 of each unit length of the
shelving assembly 10 are provided solely for the purpose of closing
these voids or gaps and imparting a closed shelving effect to the
assembly as a whole. A modicum of rigidity may be offered to the
shelving by reason of these two backboards, but their primary
function is one of preventing a direct line of vision through the
shelving assembly as a whole.
Except for size, the two backboards 24 and 26 are substantially
identical and each backboard is of rectangular configuration and
assumes the form of a relatively thin panel, the vertical side
edges of which are reinforced by stiffener strips 70 (see FIGS. 3
and 4). The length of the stiffener strips 70 is slightly less than
the vertical height of the backboards to which they are applied,
thus allowing the upper and lower edges of the backboards to fit
into the various grooves 52 and 50 in the lower and upper edges of
the rear walls 35 of the cascade units as shown in FIG. 4. Since
the slanting lower cascade unit 22 has its front wall 36 in close
proximity to the floor or other foundation surface, no vision can
be had through the lower region of the shelving and, therefore, no
backboard is necessary between the lower edge of the rear wall 35
of such cascade unit and the floor.
From the above description, it will be apparent that the backboard
structure for each unit length of the shelving assembly 10 consists
of five pieces, namely, the rear wall 35 of the lower cascade unit
22, the backboard 26, the rear wall 35 of the intermediate cascade
unit 20, the backboard 24, and the rear wall 35 of theuppermost
cascade unit 18, successively and in the order named. All of these
pieces lie in the same vertical plane and are disposed in
edge-to-edge contiguity.
The foregoing description sets forth the essential features of the
present invention when applied to a cascade shelving assembly of
the two-unit length, three-unit type wherein the principal
components of the shelving assembly are formed of wood, and the
manufacture thereof is largely a matter of carpentry work. It will
be understood that the aforementioned hook-in feature whereby the
shelving assembly is erected by the simple expedient of setting up
the two end pieces 12 and 14 and the medial divider 16 in their
approximate spaced positions and, thereafter, causing the depending
lower edge regions of the various side walls 32 and 34 of the
various cascade units to hook into and seat within the channels
which are formed by the corner reliefs 66 (see FIG. 3a) of the
supporting strips 60 will produce a stable shelving arrangement
without further fastening means. Usually, erection of such shelving
assembly is made by first causing the lower cascade units 22 to be
hooked in place, after which the assembly may progressively be
built up by applying the backboards 26, the intermediate cascade
units 20, the backboards 24, and finally the upper cascade units
18.
In addition to the structure as described above, further
rigidification or strengthening of any or all of the seven wooden
pieces which constitute each unit length of the shelving assembly
10 may be resorted to by various means. For example, as shown in
FIG. 4, the rearmost partition walls 40 of the cascade units may be
braced against the adjacent back walls 35 by inserting wedge-like
filler pieces 72 between such partition walls and back walls. Also,
if desired, stiffener strips 74 may be applied to the end pieces 12
and 14 and the medial divider 16 along the lower edges thereof as
shown in FIG. 3. Other similar reinforcing devices may be employed
wherever desired.
In FIG. 6 of the drawings, a single unit length of cascade shelving
assembly of the three-tier or unit type is illustrated and
designated in its entirety by the reference numeral 80. Except for
the elimination of the medial divider 16 and one set of cascade
units, no new components are required for the erection of such
shelving assembly. Since the same components are employed in
constructing the shelving assembly 80 of FIG. 6 as are used in
constructing the shelving assembly 10, the same reference numerals
are employed in describing the single unit shelving assembly. The
shelving assembly 80 is erected by setting up the two end pieces 12
and 14 in their approximate vertical and spaced apart positions and
then causing the various cascade units 18, 20 and 22 to be hooked
into the channels which are formed by the corner reliefs 66 of the
supporting strips 60 on he inner faces of the two end pieces 12 and
14 in the manner previously described in connection with either end
piece and the divider 16, it being understood that the backboards
24 and 26 will be applied to the grooves 50 and 52 in a manner
similar to the disclosure of FIG. 4 at the appropriate times during
erection of the shelving assembly 80.
It will be understood that an additional unit length of shelving
may readily be added to any existing shelving assembly by the
simple expedient of unhooking the adjacent set of cascade units 18,
20 and 22 fron either end piece 12 or 14 and substituting therefor
an additional medial divider 16, after which an additional set of
cascade units may be applied to the outer side of such divider
strip and the previously removed end wall finally applied to the
added set of cascade units.
The invention is not to be limited to the exact arrangement of
parts shown in the accompanying drawings or described in this
specification since various changes in the details of construction
may be resorted to without departing from the spirit or scope of
the invention. For example, although in the all-wood embodiment of
the invention illustrated and described herein, no specific means
have been described whereby the component parts of the cascade
units 18, 20 and 22, the end pieces 12 and 14, the medial divider
16, and the backboards 24 and 26, are fastened together, it will be
understood that such component parts may be secured together by
adhesive means such as glue, accompanied, if desired, by the use of
small nails or brads. However, no fastening devices are required
for maintaining in their assembled relationship the various wooden
pieces which cooperate to make up the shelving assembly 10 or 80.
Additionally, although the invention has been described in
connection with shelving which is constructed substantially
entirely of wood, it will be understood that, if desired, other
materials may be used as, for example, sheet metal, molded plastic
material, fiberglas or the like. Where molded plastic material is
employed, it is obvious that many of the parts which have been
disclosed herein as being separately fashioned and fastened
together may be integrally formed, the supporting strips 60, for
example, being integral with the end pieces with which they are
associated. Although the invention has been described in connection
with cascade shelving of the three-unit or tier type, it will be
understood that a greater or lesser number of cascade units or
tiers may be employed if desired. Whereas in the illustrated
three-unit arrangement, the various end pieces 12 and 14 and the
medial divider 16 are generally of E-sape configuration, it is
obvious that in constructing two-unit cascade arrangements, these
end pieces and medial divider will have only two forwardly and
horizontally extending webs 56 and will, thus, be generally of
C-shape configuration. Finally, although the herein described
shelving has been stated as being used principally for the display
of magazines, books, and the like, and the individual cascade units
18, 20 and 22 are illustrated as being provided with partition
walls 40 and bottom walls 42 for supporting and holding such
articles in an appropriately displayed condition, it is
contemplated that by suitable modification of the units 18, 20 and
22, they may be adapted for use in supporting other articles such
as cosmetic items. For this purpose, the various partition walls 40
may be dispensed with and, in their place, there may be substituted
two or more cascade tiers of flat horizontal shelf supports.
Therefore, only insofar as the invention is particularly pointed
out in the accompanying claims is the same to be limited.
