United States Patent O 3,525,170 CALENDAR Solomon Greenberg, 301 Tryon St, Greensboro, N.C. 27403 Filed Sept. 6, 1968, Ser. No. 758,011 Int. Cl. G09d 3/04 U.S. Cl. 40-120 5 Claims ABSTRACT OF THE DISCLOSURE A Wall calendar of the type using a pad of individually removable daily indicia sheets is provided with spring-loaded collapsible supports for the pad and a clamping cover member or cap maintained in Continous contact with the uppermost sheet as successive sheets are removed.
BACKGROUND THE INVENTION The familiar daily wall calendar configuration incorporates a pair of screws that support the calendar pad through corresponding holes in each sheet adjacent to the upper corners. The screws are retained by nuts located at the rear surface of the mount. The disadvantage of this configuration is that the heads and Shanks of the screws project progressively outward with respect to the surface of the pad as the daily sheets are removed, thereby presenting an unsightly appearance.
In accordance with the present invention a novel arrangement is provided whereby a neat and attractive appearance is maintained at the exposed surface of 'the calendar throughout the calendar year. This desirable objective is achieved by the novel arrangement hereinafter described zwhereby the dimensional relationship among the exposed parts including the upper surface of the calendar pad is automatically and constantly maintained, notwithstanding the decrease in thickness of the pad by successive removal of individual sheets.
DETAILED DESCRIPTION OF EMBODIMENT The novel features of the invention and the advantages thereof will be appreciated from the detailed description which follows read in connection with the accompanying drawings illustrating an operative embodiment. In said drawings.
FIG. 1 is a plan view of the calendar assembly in a vertical plane as it would be viewed by the user;
FIG. 2 is a side elevation of the calendar assembly;
FIG. 3 is a cross-section of a portion taken along the line 3--3 of FIG. 1 and enlarged to show the details of the supporting mechanism for the calendar pad;
FIG. 4 depicts the shape of one of the mounting holes in each disposable sheet of the calendar pad in accordance with a preferred embodiment.
The calendar pad 1 is composed in known manner of a plurality of individual printed date sheets preferably in daily sequence. The pad is held fast against a permanent base 2 by a clamping member in the form of a cap or edge cover 3 at the upper edge thereof and is suspended from the base by a spaced pair of spring-loaded collapsible posts 4 passing through suitable holes provided in the pad near the upper edge thereof and communicating with corresponding holes in the base.
The posts 4 are made up of tubular telescoping memlbers housing helical extension springs 5. While each post is illustrated in the drawings as composed of a single pair of telescoping sections, it will be understood that three or more of such intertting sections may be employed, if desired.
The inward ends of the springs are retained in the base 3,525,170 Patented Aug. 25, 1970 ICC 2 by a continuous strip 6 which is bonded or other-wise firmly attached to the base. The opposite end of each spring is anchored by a screw or bolt 7 which passes through a hole provided in the cap 3 and is retained thereon by a nut 8 screwed on to contact the outer surface of the cap 3 directly or through an intermediate washer. By this arrangement the cap 3 is constantly urged inwardly toward the base 2, exerting pressure on the uppermost exposed sheet of the calendar pad. To enhance appearance the nut 8 may be of the acorn type or other aesthetic design.
The rearmost telescoping section of each post 4 is flanged outwardly to form a lip 9 that can contact the inner surface of the forward Wall of the base 2 at the periphery of the hole through which the post passes. 'The lip 9 prevents said section from escaping in a for-ward direction from the forward wall of the base 2, during assembly operation, thereby maintaining support of the pad 1. Each rearmost telescoping section can float rearwardly as the calendar sheets are removed. The forward section of each .post 4 is provided with an inwardly turned end forming a flange 10 pressed against the inner wall surface of cap 3.
The intermediate ends 11, 12, of each of the telescoping sections of the post 4 within each hole 13 of the pad are formed to mate in overlapping relation with the next adjacent section and to provide a limiting stop against separation of the sections by outward movement but permitting free inward movement between sections as the spring contracts.
Each individual sheet of the daily calendar pad can be removed by pulling it in a plane that is approximately parallel to the surface of the pad so that the sheet will not be torn. The sheet being removed slips out from between the succeeding sheet and cap 3. The springs 5 then pull the cap 3 into contact with the freshly exposed sheet while collapsing the posts 4 by the thickness of the sheet that -was removed. The cap 3 rests upon the last sheet of the pad 1 at the end of the calendar year. A neat appearance is thus maintained throughout the year since the exposed cap 3 and the exposed nuts 8 automatically maintain their position with respect to the surface of each calendar sheet as it is uncovered. It will be understood that the springs 5 are sized in length with relation to the maximum thickness of a `fresh pad so that the pad is maintained under slight clamping pressure of cap 3 as the spring tends to contract.
As shown in FIG. 4 and in accordance with a preferred embodiment, the hole 13 in each sheet of the calendar pad may be provided at the top thereof with a cutout portion or notch 14 communicating with the hole and extending to the upper edge of the sheet. Such arrangement permits removal of each sheet in one piece and there'by minimizes the formation of unsightly pieces of torn paper. Instead of the notches 14 slits may be provided in each sheet extending from each hole to the upper edge of the sheet. The possibility of tearing the sheets in the process of removing them is further minimized by the light pressure that the springs 5 maintain between the cap 3 and pad 1. This light pressure facilitates removal -by minimizing friction between the sheet being removed and the cap 3.
Suitable hooks 15 or other attaching means are provided at the rear face of the device to enable hanging or mounting the calendar assembly on a wall or other vertical supporting surface in well known manner.
When the last sheet has been removed, as at the end of the year, a new pad may be inserted simply by unscrewing the nuts 8 and removing cap 3, then inserting the protruding ends of the posts 4 through the holes in the pad at the bottom face thereof. From the rear of the base the posts are then pushed outwardly to extended position thereby expanding the springs. While held in this expanded position the cap 3 is replaced with screws 7 being passed through the holes provided in the cap and the nuts 8 being screwed on to maintain the pad in assembled condition on the posts.
It will be understood that the present invention is not limited to the specific construction or arrangement of the parts as shown, as other modifications may be embraced therein within the scope of the claims set out below.
What is claimed is:
1. A vertically suspendible supporting structure for a calendar pad composed of individually removable date sheets; said structure comprising a base, hollow collapsible post members extending transversely from said base approximate the upper edge of the base, each of said post members 'being formed of mating telescoping sections; the rearmost section of each post member being provided with means contacting said base member and adapted to limit forward movement of said section; biasing means associated with said post members and attached to said base tending to contract said post members by relative movement between said sections; a cap member overlying the forwardmost section of the post member, said cap member being adapted to press against the upper face of a pad when such pad is operatively mounted on said post members; fastening means passing through holes in saidcap member and arranged to fasten said cap member to the post members at the extremities of the forwardmost sections of the post members, whereby said cap member is maintained constantly in fixed position to the forwardmost post sections notwithstanding longitudinal sliding movement between the telescoping sections thereof.
2.
