United States Patent 2,782,539 Patented Feb. 26, 1957 free ROTATABLE CALENDAR STAND Giles A. Baker, Scarsdale, N. Y., assignor, by mesne assignments, to Pyro Plastics Corporation, Union,
Application March 29, 1955, Serial No. 497,690
4 Claims. (Cl. 40-111) The present invention is directed to stands, more particularly to a stand of relatively small size which is adapted to be placed upon a desk or the like and to contain a rotatable cylinder employing a calendar or other printed matter.
Calendar stands or holders have been known and used. Some of them have certain disadvantages in that it is difficult to change the calendar without removing some elements in order to make the change. Others are complicated in construction and are relatively costly. Still others are unsightly in appearance or bulk.
The present invention is intended and adapted to provide a combination holder or stand and rotatable cylinder for calendars and the like, which combination is relatively small, is of simple construction, has but few parts and is inexpensive to manufacture.
It is also among the objects of the present invention to provide a stand which is attractive in appearance, the cylinder of which is refillable or replaceable, which is easy to assemble and in which the calendar or other data is given protection against outside influences such as dirt, water or the like.
It is further among the objects of the present invention to provide a stand which is stable and has no tendency to be overturned even when accidentally moved, and which may have advertising or other matter on the rear face thereof, with a calendar or the like on the front face.
In practicing the present invention there is provided a hollow body which is triangular in cross-section and is elongated so that it may rest on one of its faces on a desk or the like. The front face, which slopes rearwardly, has a substantially rectangular opening across the face thereof. A hollow cylinder of transparent material, such as a synthetic resinous composition, may itself be printed or lithographed or may carry on the inner face thereof a body or sheet containing printed or like matter such as a calendar, baseball schedule, technical information, pictorial matter, decimal equivalents, and others. The cylinder is mounted within the stand in such a manner that a small portion thereof, usually about one-fourth, extends outwardly beyond the face of the stand so as to expose to ready view the calendar or other material, which becomes readily visible. The ends of the cylinder are supported within the body of the holder so that it may be rotated by pressure of a finger on the exposed portion of the cylinder, thus progressively exposing the remaining three-fourths of the cylinder and the printed material thereon or therein.
In the accompanying drawing constituting a part hereof and in which like reference characters indicate like parts,
Fig. l is a perspective view of a calendar stand or holder made in accordance with the present invention;
Fig. 2 is a transverse cross-sectional view thereof taken along line 2-2 of Fig. 1;
Fig. 3 is a horizontal cross-sectional view of the device;
Fig. 4 is a view similar to Fig. 2, showing the several elements in detached positions;
Fig. 5 is a bottom elevational view thereof, and
Fig. 6 is a longitudinal cross-sectional view taken along lines 6-6 of Fig. 2.
The triangular hollow body or stand has a front face 1, through which the data such as a calendar can be viewed and on which face advertising or other matter may be placed, and a rear face 2 on which advertising or other matter may also be placed. The triangular body rests upon its bottom 3. Ends 4 and 5 complete the structure, which is generally molded integrally as a single unit having an open bottom. In the front face 1 is a longitudinal opening 6 having flanges 7 and 8 along the upper and lower edges of said opening. At the ends of the opening are extensions 9 and 10 which are arcuate in shape to conform with the shape of the cylinder. Similarly, flanges 7 and 8 are arcuate.
Cylinder 11, made of transparent material, has ends 12 and 13 which may be held therein by'friction, or permanently by cementing. Within the cylinder is a sheet of paper or the like 14 containing, for example, on its outer face a twelve-month calendar, as shown in Fig. 1, wherein three months are shown in alinement, or having thereon other data, as above mentioned.
Extending downwardly from within the apex of the stand are stop members 15 and 16, near the ends 4 and 5, respectively; the lower edges of which are curved to conform with the shape of cylinder 11. Slightly above the bottom of faces 1 and 2 adjacent to the ends thereof are pairs of ledges or seats 18 and 19 slightly raised above bottom 3, and having an upstanding stop 17. Two flat springs 20, one at each end of the stand, have central arcuate portions 21 adapted to conform with the shape of cylinder 11. One end 22 thereof is adapted to fit over seat 18 and against stop 17, and the other end 23 thereof is adapted to fit over seat 19 and against its stop 17 at each end of the stand. Below seats 18 and 19 are a pair of lateral projections 25 and 26 having a recess therebetween. A bottom plate 24 is inserted in the recess between projections 25 and 26 and snapped into place and held in position by the inherent resiliency of plate 24, which may be printed or embellished.
In assembling the stand, cylinder 11 with its associated parts is pushed up into place against stop members 15 and 16 and into opening 6. Then each of springs 20 is pressed against cylinder 11 and deformed so that it rides over seats 18 and 19.
Upon release of the springs, cylinder 11 is held firmly in position against flanges 7 and 8, extensions 9 and 10, stops 15 and 16 and arcuate portion 21 of spring 20.
With the calendar in position as shown in Fig. 1, when it is desired to change the month, the thumb or finger is pressed down upon the exposed face of cylinder 11 and by movement upwardly or downwardly, the cylinder is rotated and the new portion having three months in alinement is exposed to view. When it is desired to change the sheet 14 containing the calendar, bottom 24 is re moved, springs 20 are slipped out of place, causing cylinder 11 to drop out. Then, as the case may be, one of ends 12 and 13 of the cylinder may be removed, sheet 14 slipped out and a new sheet introduced therein. Or, in the alternative, a new cylinder may replace the one which has been removed. Such a cylinder may be lithographed or printed or may have a sheet inserted therein.
There are a number of advantages inherent in the present invention in that the device is small and compact, is of unusual shape and is attractive in appearance. The construction is simple and it is easy to change the calendar or other materials or to insert other data which may be referred to by the user. When sheets 14 are used, the calendar or other data is protected from outside influences since it is behind the plastic protective cylinder. The stand itself is sturdy, and is stable since it has a wide base. It lends itself to various uses and replaceable cylin ders or data may be inserted "according to the needs of the user.
Although the invention has been described setting forth a single specific embodiment thereof, the invention is not to be limited thereto as various changes in the details may be made within the principles herein set forth. For instance, the stand need not be triangular in end view, corners may be rounded and sizes and shapes of the several elements may be varied to suit conditions. The cylinder may be altered so that one or both ends are omitted and other means provided for protecting sheet 14. If the interior of the cylinder carries the printed matter, no ends are necessary. More or less than one-fourth of the cylinder may be exposed through opening 6. While it is preferred that the stand and certain of the associated elements be integrally formed, they may be assembled from various parts, and'any suitable materials may be used.
These and other changes in the details may be made without departing from the spirit of the invention, which is to be broadly construed, and to be limited only by the character of the claims appended hereon.
