This invention pertains 'to a novel display device and to a method of making the same.
The term display device as used herein refers to devices of the character described hereinafter in greater detail, these devices being adapted for use as display cards or holders for various articles such as coins, stamps, combs,.belts and other articles. Moreover, the devices of this invention may be used not only for display purposes but may also be employed as ameans of maintaining collections of articles in an attractive, orderly and permanent manner. For example, the display devices of this invention may be used to great Aadvantage as pages of collectors albums.
Although as stated hereinbefore the invention has many adaptations, in order to facilitate understanding Ythe description given hereinafter` will be particularly directed to the use of the invention in connection with philately. y
`Heretofore stamp collectors have placed stamps in albums' by using so-call'ed adhesive hinges. This method of mounting stamps in albums is not satisfactorysince hinges occupy considerable space, thereby rendering the albums unnecessarily bulky, make it almost impossible to arrange stamps Without having them askew, and often cause injuries to the stamps when it is necessary or desirable to move stamps from one page to another or for other transfer purposes.
i The'display device of this invention, when used in a stamp album, comprises a double-faced sheet of-suilicient strength and rigidity to remain flat in actual use and be free from warping or curling due to changes in temperature or humidity.
Each face of the display device is provided with a series of display areas covered by strips ofv transparent material such as cellulose acetate, Cellophane or similar transparent or translucent material. This strip material emerges from the body of the display device through very narrow slits which delineate each display area. Preferably three slits delineate each display area, the transparent strip being unattached to the face of the board along one edge so that stamps or other thin articles (negatives, snap-shots, cards or the like) may be inserted under the transparent strip. The method of forming the display cards of thepresent invention causes the transparent strips to be maintained under tension and to be deformed in areas contiguous to the slits through which the strip emerges so that objects placed beneath the transparent strip are firmly held thereby but are Vreadily accessible and visible to the observer or user.
- namely, the upper sheet 28 Other objects, uses,A advantages and adaptations of the invention'will become apparent to those skilled in the art from the following detailed description of certain exemplary forms of the present invention. Reference will be had tov the appended drawing, in which:
Fig. 1 is a plan View of a displaydevice made Y in accordance with the present invention.
Fig. 2 is an enlarged plan View of one portion of the display device.
- Fig. 3 is an enlarged transverse section taken along the plane III-III of Fig. 2, the lower portion of Fig. 3 being flared to more clearly show the various members employed.
Fig. 4 is a planview of a portion of a modied form of display device. Fig. 5 is an enlarged transverse section taken along the plane V-V of Fig. 4, a coin held by the display device being shown in end elevation, the lower portion of this section showing the component parts separated in order to facilitate understanding.
As shown in Fig. l, the display device, generally indicated at I0, comprises a plurality of display areasjII, I2, I3, I4 and I5, delineated iby the narrow marginal slits, such as the slits I6, I 'I and I8 of the area II. Each display area iscov-Y ered by a strip of transparent material, the upper edge of the transparent material at 2|, 22, 23, etc. When used .as a page of a stamp album, stamps may be inserted between the face of the device and the transparent strips, the transparent strips then holding the stamps in position as indicated in the two examples Vgiven at 25 and 2S.
Although Fig. l is a plan view of one face oi a displaydevice, the reverse side may be of identical structure.
The enlarged planview shown in Fig. 2 more clearly illustrates the arrangement of the parts, the transparent strip being indicated at 21.
The transverse section of Fig. 3 shows the reverse side of the display device in a partially torn away'positlon for the `purpose of emphasizing the construction. 1
It will be noted that the device III comprises two sheets of material of appreciable thickness, and the lower sheet 29. When the display devices are made -of cardboard, vit has been found desirable to employ aV being indicated multi-ply board, and preferably a board of a thickness not thinner than a two-ply board. In ordinary practice, a four-ply board has been found eminently suitable. Each of these sheets of material, such as the sheet 28, is then die cut to provide narrow slits delineating display areas. The slits should dene not less than two margins of the display area and as shown in Fig. 1, three slits I6, I1 and I8 delineate the display area II. The narrow slit I1 is shown in Fig. 3. In making the display device, a strip of trans parent material is passed through the slits I6, I1
and I8, each strip extending over the display area and having its ends overlying thev rear sur.- face of the sheet adjacent the slits. For example, in Fig. 3 the upper edge of the strip 21 is indicated at 2I but the lower portion of the transparent strip 21 extends througlr the slit I1 and extends through the rear surface of sheetli!y adjacent the slit, as at 21. By referring to transparent strips, reference is m'ade to translucent materials as well. Strips of Celluloid or Cellophane (either transparent and uncolored or colored, frosted or translucent) may be employed. Certain synthetic materials in thin sheet form may be used to good advantage.
The companion sheet 23 is similarly provided with narrow slits delineating various display areas and similar strips of transparent material are positioned over the display areas as, for example, the strip 30. The two sheets 28 and 29 are then placed in back to back relation with a sheet of pressure bonding material 3l positioned therebetween. Preferably the pressure bonding material 3| is coextensive in area with the entire area of the sheets 28 and 29. The material 3I may comprise a thin sheet of thermoplastic material or a cellulosic web coated or impregnated with a pressure bonding substance, resin or oomposition. Thin sheets of paper saturated with shellac, plasticizers and other resins may be employed to good advantage. The entire assembly, including sheets 28 and 29, the transparent strips carried thereby and the intervening layer of pressure bonded material 3|, is then subjected to pressure and in somev instances to heat as well as pressure. The amount of heat employed depends upon the character of the pressure bonded material used between the two sheets 28 and 29.
Materials requiring temperatures sufficiently high t0 discolor the transparent materialsl21 and 30 should not be employed.
After the pressure has been removed, it will `be found that the intervening layer 3l is substantially indistinguishable as a separate layer and has rmly bonded the sheets 28 and 29 together. Moreover, the pressure (and heat) has now caused the transparent stripsY 21 and 30 to become deformed in areas contiguous to the slits defining the display areas. For example, the strip 21 has now been deformed so as to form a corner 32 where such strip entersrthe slit I1. The application of pressure during the bonding and assembly has moreover placed the strip 21 under tension so that it lies closely adjacent the outer surface of the sheet 28 and will not stretch or distort during prolonged use.
It will be noted that in the event a card, snapshot or stamp is inserted beneath the strip 21, l
the lower part of the stamp will abut the deformed portion of the strip at the corner 32 and inasmuch as the strip 21 is under tension, the stamp, card or snap-shot will be firmly held between the sheet 28 and the strip 21 so as not to be dislodged from its position. Moreover, since the sheet 28 is of appreciable thickness and is an inherent structural portion of the finished display device, there are no loose or insecure surfacing elements which may peal from the working surface of the display device.
The modification shown in Figs. 4 and 5 is particularly adapted for use with objects of appreciable thickness, such for example, coins, metals,`buckles, straps, belts, articles of jewelry, and the like. Whereas the display device of Figs. 1, 2 and 3 had display areas delineated by three narrow slits dening the boundaries of each display area, such slits being in intercommunica tion, each` display area of the device shown in Figs. 4 and 5 is delineated by only two slits, one at each end, a narrow slit 4I! being indicated in Fig. 4, such slit constituting one end of a display areaA covered by the transparent strip 4I. The deviceitself is formed of two sheets of material 42 and 43, the slits delineating the margins of the display areas carried by each of such sheets being substantially superimposed when the two sheets are placed in back to back relation.
In addition, each display area may contain one or more cut-out portions or apertures. Ifyfor example, the display area is to receive a plurality of coins or metals, the sheet 42. within the boundaries of the display area 4I may be provided with circular apertures 44, 45, and the like.
Sheet 43 is provided with identical apertures,'as
Ysuch as end slit V4l), so as to extend onto the rear or back side of the sheet 42, as indicated at 4I A similar strip of transparent material 41 is caused to extend over the display area of sheet 43 and the end portions of strip 41 pass through slits delineating the ends of such display area.
The two sheets 42 and 43 are then bound together by means of an intermediate layer or strip of pressure bonding material 48. The transparent strips 4I and 41 are placed under tension during this cementing process and are firmly held over the display areas.
'In actual use, suitable coins may be placed beneath the free edges of the transparent strips, such as strip 4I, and slid into the pocket formed by the registering apertures of sheets 42 and 43 such as, forexample, the apertures 44 and 46 shown in Fig. 5. When so mounted, the coin, metal or other object is retained in position within the display device but is clearly visible to ob- 'servers so that both the front and reverse sides of a coin or metal may be examined without removing it from the display device. When the display devices of this invention are employed in book form, 'as in collections of coins, stamps, or other objects, they may be provided with a hinged end portion, such as the portion 50 provided vwith perforations 5I, 52, and the like, adapted to fit into a loose leaf binder or other binding means. The portion 50 may be attached to the display device by means of a flexible Webbing 53 cemented to the strip 50 and to the display device, thereby permitting the display device to be freely moved and turned while held within a suitable binder, standard or the like.
Numerous modications and changes may be made in the form of the invention as will be readily apparent to those skilled in the art. All changes and modications coming within the scope of the appended claims are embraced thereby.
