Description
Background of the Invention
1. Field of the Invention
This invention relates generally to a display stand, and more particularly to a paperboard display stand having a base of tubular construction which is formed from one-piece blank of foldable sheet material such as paperboard.
Summary of the Invention
It is the object of the invention to provide a paperboard display stand having a tubular base which may be formed on conventional box-making equipment and which is completely collapsible and can be quickly erected.
A more specific object of the invention is the provision of a paperboard display stand having a tubular base with upper and lower portions separated from each other, whereby certain sections of the upper portion can be folded in face-to-face with other sections of the upper portion to provide a reinforced area capable of supporting one or more shelves.
These and other objects of the invention will be apparent from an examination of the following description and drawings:
Brief Description of the Drawings
FIG. 1 is a fragmentary perspective view of a display stand embodying features of the invention;
FIG. 2 is a fragmentary vertical sectional view of a portion of the structure illustrated in FIG. 1;
FIGS. 3 and 4 are perspective views similar to that of FIG. 1, but illustrate the manner in which the base portion of the display stand is assembled;
FIG. 5 is a perspective view of the tray of the display stand;
FIG. 6 is a perspective view of the tray supporting structure for the display stand;
FIG. 7 is a perspective view of one of the shelves of the display stand;
FIG. 8 is a perspective view of the header of the display stand; and
FIGS. 9, 10, 11, 12 and 13 are plan views of blanks of foldable sheet material from which the structures illustrated in FIGS. 4, 5, 6, 7, and 8, respectively, may be formed.
It will be understood that, for purposes of clarity, certain elements may have been intentionally omitted from certain views where they are believed to be illustrated to better advantage in other views.
Description of the Preferred Embodiment
Referring now to the drawings for a better understanding of the invention, and particularly to FIG. 1, it will be seen that the novel display stand DS embodying features of the invention includes a generally tubular base member, indicated generally at B, together with a tray T, a tray support TS, one or more shelves S, and an advertising header or display panel H.
The primary novelty of the invention resides essentially in the design and construction of the base B which, as best seen in FIGS. 3 and 4, is formed from a conventional tubular structure which may be assembled on ordinary box-making equipment and which is collapsible and can be readily assembled.
Base B may be formed from a unitary blank BF of foldable paperboard illustrated in FIG. 9.
Referring to FIG. 9 it will be seen that blank BF includes from left to right a rear side wall panel 10, a first end wall panel 12, a front side wall panel 14, a second end wall panel 16, and a connecting flap 18, all of which are foldably jointed to each other along parallel fold lines 13, 15, 17, and 19, respectively.
By securing the connecting flap 18 to rear side wall panel 10 in any desired manner, such as by gluing or stapling, a tubular structure is formed, as best seen in FIG. 3. Still referring to FIG. 9, it will be seen that front side wall panel 14 and the front portions of end wall panels 12 and 16 are divided into upper and lower areas by means of cut lines 21b and 21a, respectively. The remaining portions of end wall panel 12 and 16 and rear side wall panel 10 may be divided into upper and lower portions by fold lines 23b and 23a, respectively in order to fold the blank or glued tube in half for convenience of shipping or storing.
It will be seen that the upper portions of panels 10, 12, 14, and 16 and connecting flap 18 have been designated as 10a, 12b and 12a, 14a, 16a and 16b and 18a, respectively, and are foldably joined to each other on fold lines 13a, 15a, 17a, and 19a, respectively. Also the upper portions of panels 12 and 16 are divided by fold lines 11a into panels 12a and 12b and 16a and 16b, respectively.
As best seen in FIG. 4, cut lines 21a and 21b permit the upper portion 14a of front side wall panel 14 and the front sections 12a and 16a of the upper portions of end wall panels 12 and 16 to be pushed rearwardly so as to lie against the inner faces of upper portions of rear side wall panel 10 and rear sections 12b and 16b of upper portions of end wall panels 12 and 16, respectively.
Thus, the upper portion of the tubular base is double ply, so that it is strong and capable of supporting shelves as described later in the specification.
It will be seen that the upper portions of end wall panels 12 and 16 are provided with openings 25 for receiving end portions of shelves in a manner hereinafter described. Also the upper portions of front and rear side wall panels 10 and 14 are provided with slots 27 which also receive portions of shelves as described hereinafter.
Referring now to FIGS. 5 and 10 of the drawings. it will be seen that the tray indicated generally at T in FIG. 5 may be formed from a unitary blank BT of foldable paperboard illustrated in FIG. 10.
Tray T includes a central panel 30 having a pair of opposed front and rear flanges 32 and 34 foldably joined to the front and rear edges thereof on fold lines 33 and 35, respectively, and disposed to extend upwardly therefrom. Tray T also includes a pair of opposed end flanges 36 which are foldably joined to opposite end edges of panel 30 on fold lines 37. End flanges 36 are also disposed to extend upwardly from panel 30 to provide a tray structure which can be inserted within base B, as shown in FIG. 1.
In order to support the tray T and maintain it in proper position, there may be provided a tray support structure, indicated generally at TS and illustrated in FIG. 6, which may be formed from a pair of blanks BTS of the type illustrated in FIG. 11.
It will be seen that each of the blanks BTS include a main panel 40 having a slot 41 adapted to mate with a related portion of another panel to provide a cross-shaped structure, as shown in FIG. 6, for supporting the tray.
As previously mentioned, the base may be provided with one or more pairs of opposed slots 25 adapted to receive one or more shelves S, of the type illustrated in FIG. 7, which may each be formed from the unitary blank BS illustrated in FIG. 12. Each of the shelves S includes an upper panel 50 a front panel 52 a sloping rear panel 54 and a lower panel 56 which are foldably joined to each other on fold lines 53, 55, and 57, respectively. Each of the upper and lower panels 50 and 56 may be provided with an integral, rearwardly projecting, generally T-shaped lock tab 58a adapted to be received within complimentary slots 27 of front and rear side wall panel upper sections 10a and 14a.
Still referring to FIGS. 7 and 11 it will be seen that each of the shelves also includes side projections or extensions 58b which define, with the central portions of the shelves, slots 59 adapted to mate with slots 25 in the portion of the base, as best seen in FIG. 1, to provide a means of attaching and maintaining the shelves in position on the base. The triangular structural arrangement afforded by the front and rear narrow panels 52 and 54 of each shelf serves to provide added strength and rigidity for each shelf.
In order to have a place for a display or advertising material there may be provided a header indicated generally at H and illustrated in FIG. 8, which may be formed from blank BH of paperboard illustrated in FIG. 13. Header H includes a main panel 60 having corners recessed at 61 to provide a central downwardly projecting portion or extension 63 adapted to be received between the upper portions of the front and rear side wall panels, as best shown in FIG. 1.
Thus, it will be seen that the novel display stand DS includes many features and particularly the unique base structure, as previously described, which may be formed from a one-piece blank of foldable paperboard and may be pre-glued on conventional equipment, so that it can be readily erected and assembled.
