INVENTOR DON F. PASCHAL ATTORNEYS DISPLAY MOUNTS FOR CALENDAR PADS OR THE LlKE Don F. Paschal, St. Charles, 111., assignor to Chronicle firllillrllishing Company, St. Charles, 111., a corporation of Filed Feb. 8, 1960, Ser. No. 7,203
3 Claims. (Cl. 40-120) This invention relates to display mounts for supporting calendars, memo pads and the like on a desk and more particularly to such mounts of the type having an easel leg which is folded flat for shipment and swung into supporting position when the mount is set up for use.
Such display mounts are generally distributed in large numbers to the public without charge as a part of advertising or promotion campaigns. According, they must be inexpensive, ornamental and easy to use.
It is the principal purpose and object of the present invention to provide improved display mounts which satisfy these requirements to a unique degree.
In accordance with the present invention the display mount is fabricated from a single piece of stitf cardboard or like sheet material called board which is cut and scored in a single operation and folded to form the finished mount. The folded mount includes a main body portion for supporting a calendar or the like and a lower inclined base body portion which usually carries advertising. When the mount is erected it rests on the lower edge of said base portion and on a leg carried by the main body portion. The lower base portion is provided with an integral locking tongue, the tongue and the leg being arranged in a novel manner and having unique cooperating locking formations by virtue of which the mount may be erected for use by inclining or tilting one of the body portions with respect to the other. When the body portions are relatively inclined, the leg is smoothly cammed into supporting position and at the conclusion of this movement the leg and the locking tongue are automatically locked in mount supporting position.
Additional objects and advantages will become apparent as the description proceeds in connection with the accompanying drawings in which:
Figure 1 is a plan view of the unfolded blank from which the mount is formed, the figure showing the blank after it has been cut and scored;
Figure 2 is a front view of the mount after it has been folded into final position and as it appears ready for shipment;
Figure 3 is a side view of the mount erected for use; and
Figures 4 and 5 are fragmentary rear views of the mount illustrating respectively an intermediate and final position of the locking formations on the leg and the tongue.
Withcontinued reference to the drawings, the blank from which the mount is formed is a sheet of relatively stiff paper board or like sheet material preferably covered on one side with a thin decorative paper sheet which may be imprinted with advertising. The blank 10 is provided with body panels 12, 14, 16 and 18. The panel 12- is separated from panel 14 by a score line 20 extending completely across the blank parallel to the ends 22 and 24 of the blank. The panel 18 is similarly separated from the panel 16 by a score line 26 parallel to the score line 20.
Projecting from the lower end of the main portion 2,976,631 Patented Mar. 28, 1961 of the panel 18 is a locking tongue 28 having inclined side edges 36 and 32 and an end edge 34 from which extensions 36 and 38 project. An opening 40 is provided in the tongue 28 and is positioned so that edge 34 is in alignment with its inner edge and the edge of extension edge 36 substantially bisects the opening. A leg 42 is cut from the panels 14 and 16, the leg being completely severed from the panel except for two scored lines 44 and 46 which form a hinge about which the leg 42 may be swung. Since the portion of the leg 42 which extends into the panel 16 is completely severed from the panel, the scored lines 48 and 50 connecting the panels 14 and 16 extend inwardly from the edges of the blank only to the adjacent edges of the leg 42. A portion of the leg 42 is cut away to form an opening 52 having an integral projection 54 extending from its inner edge and a recess 56 cut from its opposite edge.
All portions of the blank are carefully dimensioned to permit the blank to be folded to the position of Figure 2 and to be erected automatically in the position ,of Figure 3. For example, when the panel 12 is folded about score line 21) the edge 22 is disposed closely adjacent the'score lines 48 and 50. Similarly, when the panel 18 is folded about the score line 26, the edges 58 and 66 of the main body portion of the panel are also disposed closely adjacent the score lines 48 and 50 and the leg 28 lies substantially entirely beneath the panel 12.
It will be noted that the panels 12 and 18 are of less width than the panel 12 to expose the edge of the latter. The panel 12 is preferably covered with a decorative paper of contrasting color which is thus exposed for decorative purposes.
When the panel has been folded into the position of Figure 2, it is retained in folded position by fastening the panel 12 to the panel 14 as by staples 62. This automatically retains the panel 18 in the desired folded position. The panel is completed by stapling a calendar or like article to the front face of the folded panel 12.
The display mount may be erected for use by simply grasping the upper edge of the folded panels12 and 14, placing the lower edge of the folded unit on the desk,
and pushing downwardly on the top of the panel while tilting it slightly to the rear so as to cause the panel to bend along the single thickness score lines 48 and 50. This action causes the locking tongue 28- to swing outwardly thus smoothly camming the main leg 42 to the rear out of the plane of the panel 14 about the upper hinge formed by the score lines 44 and 46. This movement is continued until the outer edge of the projection 38 on the tongue 28 passes the edge of the projection 54 on the easel leg 42. Because of the natural resiliency of the hinge formed by the score lines 44 and 46, the leg 42 will then move slightly back toward the plane of the panel 14. The projection 38 will then enter the recess 56 until the end of the projection 36 engages the surface of the leg 42 beyond the ends of the recess 56 as shown in Figure 4. If the mount is now released the tongue 28 will snap upwardly to position the projection 54 on the leg 42 in the opening 411 thus locking the leg securely into position as shown in Figures 3 and 5. The assembly tends to remain securely in erected position since the natural resiliency of the material at the hinge lines 48 and 5t and 44 and 46 maintain the projection 54 firmly in the opening 40. Further, in erected position the engagement of the surface of projection 36 with the lower edge of the recess 52 effectively prevents accidental disengagement of the parts.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims'rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
What is claimed and desired to be secured by United States Letters Patent is:
1. A display mount for a calendar or the like comprising a single piece of stiff board having first, second, third and fourth body panels, each panel being joined to the adjacent panel by a scored hinge line, said first panel being folded on a hinge line to lie in surface contact with said second panel and said fourth panel being folded on a hinge line to lie in surface contact with said third panel, the edge portions of said first panel and said fourth panel being disposed closely adjacent the hinge line between said second and third panels, said fourth panel having a locking tongue projecting therefrom beneath said first panel, a leg connected to said second panel by a hinge parallel to the score line joining said first and second panels and between the score line joining said first and second panels and the end of said tongue and having a portion opposite said tongue whereby when said third and fourth panels are swung about the hinge line joining said third panel to said second panel, said tongue will move said leg into mount supporting position, and cooperating locking formations on said leg and said tongue engageable to retain said leg is said supporting position.
2. The combination according to claim 1 wherein said locking formations comprise openings formed in said leg and said locking tongue and respective projections are provided on said leg and said tongue extending through the opening in the other member.
3. A mount for supporting a calendar or the like comprising a panel having a main body portion for carrying said calendar and a base portion, said main body portion and said base portion being joined by a hinge construction, a leg connected to the rearward side of said main body panel by a hinge parallel and adjacent to the edge of said main body portion remote from said hinge construction, a locking tongue formed integrally with said base portion and disposed beneath said leg when said main body portion and said base portion are coplanar and adapted to extend rearwardly of said main body portion when said base portion is tilted with respect to said main body portion, said locking tongue and said leg each having openings therein and said locking tongue and said leg each having projections extending into the opening in the other member to lock the parts in predetermined position.
