ATTORNEYJ United States Patent 3,251,151 PORTABLE DISPLAY DEVICE Walter H. Sherrill, P.O. Box 74, Gastonia, N.C. Filed July 9, 1963, Ser. No. 293,767 Claims. (Cl. 40-152) This invention relates to display devices and more particularly to portable displays for sheet material such as placards and photographs.
Professional persons such as hairdressers, artists, photographers, cosmeticians, opticians, restauranteurs and the like have found benefit from displaying at their places of business and elsewhere, photographs or other likenesses and representations of the appearance of their product or the result of their services. It has been found that these displays are more effective when they are attractively framed and when they are changed often enough to maintain the attention of regular passers-by. Displays of this nature are also useful to other professional persons such as teachers, lecturers, instructors and the like who desire to hold the attention of their audience while illustrating their dissertation with visual material placed on placards, diagrams, photographs, blueprints or the like.
It is a primary object of the present invention to provide a display device for interchangeable placard-like displays which includes a frame that is carried by the display device and can be easily changed for another without disturbing the remainder of the display.
It is another object of the invention'to provide a display device adapted to hold a plurality of displays, one behind the other in spaced relation, in which one or more of the displays can be withdrawn from the display to expose others of the displays to view.
Yet another object of this invention is to provide a display device simulating a framed portrait, in which either the frame or the portrait portions of the display can be changed for other frames or portraits without disturbing the remaining portions of the display device.
' Still another object of the present invention is the provisionof a display device of the character described, that is portable, can be hung on a wall or supported on a table, and can accommodate displays of varying sizes.
A further object of the invention is to provide a display device of the character described having means to space the placard-like displays from one anotherand reinforcing means on the edges of the displays to cooperate with the spacing means and prevent undue wear on the displays as they are interchanged.
These and other objects of the invention will appear and be more fully set forth in the following detailed explanation having specific reference to the attached drawing wherein embodiments of the invention are shown, not to limit the scope thereof in any respect, but in order that the principles thereof might be more easily under stood.
In the drawings:
FIGURE 1 is an exploded embodiment of the novel display device;
FIGURE 2 is a side elevation view of a first modifica: tion of the device;
FIGURE 3 is a front elevation view of the device of FIGURE 2 having the displays and frame removed;
FIGURE 4 is a fragmentary side elevation view similar to FIGURE 2 showing a second modification of the device with parts in section; and
FIGURE 5 is a fragmentary perspective view of a display having a preferred form of reinforcement thereon.
A display device embodying the principles of this invention is illustrated at in FIGURE 2. As shown, the device 10 includes a backing plate 12 which may conveniently be formed from relatively stiff sheet material,
perspective view of an- 3,251,151 Patented May 17, 1966 such as metal, plastic, composition board, cardboard or the like, depending on the desired durability. Secured to the front face 14 of the backing plate 12 is an L-shaped support 16 which extends generally perpendicularly from the plate. The support, as illustrated, comprises a sheet of bendable material such as metal having generally triangular braces 18 formed by bending the sheet downwardly at the sides thereof. The leading edge of the support 16 is preferably bent upwardly to form a flange 20 extending in a plane generally parallel to the backing plate 12. It should be realized that the support 16 could be formed by alternative methods, such as injection molding from plastic material. The support 16 is preferably fixedly secured to the backing plate 12 as by riveting, spot welding, bolting or any other conventional technique, although in the interest of greater portability, the support 16 may be removably mounted as by a tongue and groove arrangement, pin and slot, or bolt and wing nut.
A second support 22 is preferably removably and adjustably mounted adjacent the upper edge of the backing plate 12 as by wing nuts 24, bolts 26 extending through elongated vertically extending slots 23 in the support 22. The support 22 is most conveniently formed similarly to the support 16 including triangular braces 28 having an L-shaped configuration with one leg 30 thereof projecting substantially perpendicularly from the outer surface of the backing plate so that its lower surface is generally parallel to the upper surface of the support 16. A flange 32 is preferably formed at the outer extent of the support 22 as to have a portion 33 extending downwardly toward the support 16 and a second portion 34 extending upwardly from the leg 30.
A spring such as a leaf spring 36 is mounted on the backing plate intermediate the supports 16 and 22 as by riveting, spot welding and the like, for purposes more fully described hereinafter.
As best shown in FIGURES 2 and 3, alternate means, such as a key-hole slot 38 and a standard 40 removably engageable with slotted straps 42, may be provided to support the display device 10 in an upright manner, as by hanging on a wall or standing on a table.
Additionally, a light 44 may be provided for the display device, as by securing its bracket 46 to the securing means 24, 26 of the upper support member 22.
In the preferred form shown in FIGURES 2 and 3, a plurality of pairs of oppositely disposed channels 48 are provided in the form of generally U-shaped member extending parallel to one another on the lower surface of the upper support 22 and the upper surface of the lower support 16.
In use, a plurality of placard-like displays 50 are slidably received between the upper and lower supports in the cooperating channels 48 mounted thereon. The channels serve to isolate the displays from one another so that the rear surface of one display does not damage the front of the display behind it. A picture frame 52 having hanging means, such as a ledge or hook'54 on the back surface of one edge thereof, is then hung on the upwardly-directed flange 34 so that the display when viewed from the front has all the appearance of a framed 3 out disturbing the displays and that the displays can be changed without disturbing the frame.
The forms of the display device shown in FIGURES 1 and 4 are especially adapted to receive wooden picture frames. In these embodiments the upwardly-directed flange portion has been replaced by a plurality of upwardly-directed sharp end pins 56 which slightly penetrate a wooden picture frame 58 removably supported thereon to give the displays the effect of being framed by a wooden frame.
As illustrated in FIGURES 1 and 4, the-channels 48 can be removed or omitted to reduce the cost of the display device, and, in that case, the leaf spring 36 acts on the rear of the rearmost display to urge the displays toward the front of the device so that the frontmost display is retained by the flanges 20 and 32.
Various identifying means, such as tabs 60, may be secured to the displays so that the display changer can be sure of which display he desires to use without the necessity of withdrawing each. display to look at it. The tabs 60 are preferably of a size and placement so as to be observable from the side of the display but hidden from viewers in front of the device by the frame.
Referring again to FIGURES 2 and'3, the upper support 22 is movable vertically to accommodate displays that differ somewhat in height, as by loosening the wing nuts 24, moving the support and again fastening the nuts. In the modified form shown in FIGURE 4 a coil spring S in tension is mounted between the support 22 and the backing plate 12 so that the support will be biased downwardly into engagement with the displays carried between the support 16 and the support 22.
,If it is contemplated that the displays will be changed often, and it is desired to protect the edges and corners of the same, suitable reinforcing means, such as the frictionally-engaging member 62, shown in FIGURE 5, may be mounted thereon. These members 62 can conveniently be formed from metal or other materials, such as self-lubricating thermoplastic, to also aid the displays in sliding with respect to supports 16 and 22 and 1 display device of the present invention provides a notably superior means for interchangeably displaying a plurality this invention might quite profitably be employed by persons, such as professional photographers, in order to show patrons how their picture would look framed with various frames, or to show the patrons how various types of portraits are complemented by a particular frame. As noted above, the displays of the invention are usable to a distinct advantage not only by photographers but also by other artisans, educators, professional persons and purveyors of goods and services.
Although the embodiments shown in the drawings and discussed above constitute preferred forms of the display device of the invention, their purpose is .to illustrate the principles of this invention and not to limit the scope of the invention in any manner. It should be apparent that many modifications may be made on the modifications shown without departing from the principles as taught herein and, therefore, the compass of this invention should be limited only by the spirit and scope of the claims appended hereto.
