SOUND EMITTING DEVICE Filed Jan. 25, 1961 8 INVENTOR. |6 2O f 46 32 CHARLES R. LUCHSINGER *i ATTORNEYS United States Patent O York Filed Jan. 23, 1961, Ser. No. 84,300 9 Claims. (Cl. 46-34) This invention relates to a greeting card, display device or greeting folder in general and more particularly relates to a sound producing Igreeting card, display device or greeting folder which when folded lies flat and when opened emits sounds of a predetermined characteristic.
Various attempts have been -made to provide display devices, greeting cards or folders emitting sounds and noises in conjunction with the visual presentation normally provided. Heretofore, clickers, snappers and whistlers have been used with such devices to make noise or sound when actuated in some manner, such as when compressed. However, these types of noisemakers are not satisfactory when used in -greeting cards or devices intended to be sent via mail, since they are bulky, and ordinarily prevent the greeting card, device or folder from lying at when folded, and also require a heavier paperboard to be used to prevent the individual sheets from ltearing when the noisemaker is operated. Further, these noisemakers are relatively expensive and not ordinarily self-actuating, but require a separate actuating movement of the user for operation such as compressing the noisemaker. Additionally, the characteristics of `the sound obtained from these noisemakers are limited by the type of device and are difficult to incorporate in the card or device.
Therefore, it is an object `of the present invention to provide a greeting card, display device or greeting folder which will emit a sound of a predetermined characteristic automatically when the lgreeting card is opened.
It is a further object of the present invention to provide a greeting card or greeting folder made from a single sheet of material, such as paper, cardboard or the like, which lies flat when folded and may be inserted in an ordinary mailing envelope and which provides sound when the card is opened without a separate actuating effort by the user.
Still another object of the present invention is to provide a display device which emits sounds of various pitches or characteristics upon opening the device.
A still further object of the present invention is to provide a greeting card which emits a sound whenever opened or closed and which characteristic of the sound can be easily varied.
A still further object of this invention is to provide a greeting card, greeting folder or other type display device producing sounds of predetermined characteristic requiring no special sound producing devices or special means of mounting such devices.
A still further object of the present invention is to provide a greeting card which accomplishes all of the above and which is inexpensive, simple and economical to manufacture, positive in operation and durable in use.
Other and more detailed objects of the invention will be more apparent when the following description is considered in connection with the annexed drawings in which:
FEGURE l is a perspective, elevational view of a greeting card in accordance with the present invention showing the panels of the card separated slightly;
FIGURE 2 is a perspective view with the card in semiextended position;

FIGURE 5 is a cross-sectional view similar to that shown in FIGURE 4 showing the card in its fully extended position.
Referring now to the drawings, a greeting card is shown embodying the features of this invention, which is made from a single sheet of paper, cardboard or the like 12. Sheet 12 is advantageously scored twice transversely at 14 yand 16 intermediate of its side edges to divide sheet 12 into three integral panels or sections 18, and 22. As shown, panel 22 forms the front face and panels 26 and 1S form the inner surfaces of card 10 and abut when card 10 is folded. The upper and lower edges of panel 1S are cut or notched adjacent fold-line 14, such as by grooves or cuts 24 and 26 on the upper edge and 28 and 39 on the lower edge. Grooves on the upper and lower edge receive the sound or noise-making element, which in the embodiment illustrated is a rubber band 32. The depths of these cuts and their longitudinal double thickness with a continuous front face.
positioning may vary as will be discussed hereinbelow.
Panels 18 and 2G have a pair of spaced apart, longi- -tudinally extending slits or cuts therein 34 and 36, which intercept fold line 14 and are shown parallel. Disposed between corresponding ends of slits 34 and 36 are transverse score `or fold lines 38 and 40. As shown, score line 3S is in panel 20 and score line 40 is in panel 18. Slits 34 and 36 and fold lines 38 and 40 define an area or flap 41. Flap 41 is divided by a score or fold line 46 into a pair `of panels 42 and 44. Fold line 46 is contained within a vertical plane passing through fold line 14 and is parallel therewith.
The Card is formed by folding sheet 12 about fold line 16 so that 4the rear faces of panels 20 and 22 abut and the front of card 1i? is the forward face of panel 22. The rear faces of panels 20 and 22 are secured together in some convenient manner, such as by placing adhesive therebetween or stapling. When panels 20 and 22 are folded las shown in FIGURE 2, the left hand panel is of This is desirable since the front of the card can be fully utilized for printing thereon a message or design or other indicia. While a double thickness as yshown is desirable, it is not essential to the present invention.
Sheet 12 is further folded transversely on fold line 14 so that panels 18 and 20 abut as shown in FIGUREl. Panels -42 and 44 are lfolded outwardly, in an opposite direction along fold lines 38, 40 and 46. Fold line 46 is directed toward the outer transverse edges of panels 1S Iand 20. Rubber band 32 is placed in a notch in the upper and lower edges of panel 18 and as shown in FIG- URE 2 is positioned in notches 26 and 30 and stretches over panel 44.
By folding card, 10, along fold lines 14 and 16, as shown in FIGURE l, card 1G can be conveniently mailed in a convention-al envelope. r[The rear surface of panel 42 is juxtaposed against the rear surface of panel 44, so that card 10 li, relatively iiat in its closed position, as partly illustrated in FIGURES 1 and 3. In this folded position, rubber band 32 is urged into position along fold line 40 and is maintained therebetween panel 44 and panel 1S, as indicated in FIGURES l and 3 and by dashedv line 32a in FIGURE 2. In this position rubber band 32 is in tension or sn'etched.
When the card or folder is unfolded to the position shown in FIGURE 2, panels 42 and 44 are drawn inwardly towards panels 20 and 18 respectively. With panel 44 being drawn inwardly towards panel 18, the natural pull of tensioned rubber band 32 causes rubber band 32 lto move along the surface of panel 44 towards fold line 46 in the direction of arrow 50 as illustrated in FIGURE 4. The positions of rubber band 32 illustrated by dashed line 32a and solid lines 32 in FIGURES 2, 4 and 5 are illustrative of three positions through which the rubber lbandi-moves during the normal `card unfolding process. The movement of the rubber Kband across the surface of panel 44 provides sound havin-g charac- .teristics which are determined in part by the size and tension of the rubber band and the dimensions of panel 44. This sound is continuously emitted during the movement of the rubber band. lIn producing sound, panel 44 acts asa sounding board when the card is opened and the at surfaces of Vthe rubber band, which is preferably square shaped, acts as the sound inducer as the rubber band rolls across panel 44. l Y I In the cards normally open or unfolded position as seen in FIGURE 5, rubber band 32 comes to rest on surface 4'4 adjacent fold-line 46 and panels 42 and 44 remain spaced from panels 20 and 18 respectively. Thus, rubber band 32 is maintained on panel 44 and fiap 41 is folded in the proper direction when card is refolded. In refolding card 10, panels 42 and 44 move outwardly and band 32 moves in a direction opposite to that shown by arrow 50 and panels and band assume the positions as seen'in FIGURE 3. Rubber -band 32 in moving along the surface of panel 44 again emits sound or noise. In its closed position rubber band 32 is at rest along foldline 40 between panel 18 and panel 44.
'Ilhe characteristic of the sound emitted by the movement of rubber band 32 can be varied depending upon the tension and thickness of band 32 or the dimensions of panel 44'. An easy manner of varying the tension is to provide a series of notches along the upper and lower edges of panel 18 between fold-lines 14 and a plane con- 4 member was shown mounted on the rear panel 18, since this has been found to be the most advantageous in allowing fuller use of the front panel. However, the sound producing element may be mounted on panel 20. Further, a sound panel may be provided for actuating the sound emitting member by moving away Ifrom the card panels when the card is opened.
There is thus shown a greeting card or greeting folder with anl outside Iface provided with design, illustrative material or printed matter of some type and having some type of sound, emitted automatically upon the opening and closing of the card, yet which card can be formed inexpensively of paperboard or paper and mailed in its n folded position in an ordinary and conventional type envelope. The sound producing member is inexpensive and requires no special further acts of the receiver to actuate. Y
Since many apparently differing structures may be readily devised by those skilled in the art without departing from the scope of the invention, it is understood that the foregoing description is illustrative only, the scope of the invention being defined solely by the claims granted Y to me.
Y said first and second panels intersecting said fold-line,
taining fold-line 40. Thus, if the rubber band 32 was l between parallel planes passing respectively through foldline and notches 24 and 28. While only two notches along the upper and lower edges off panel 18 are shown, more can be provided to provide further versatility. Additionally, the distance of the notch from fold-line 40 will determine the duration of the sound emitted. Thus, notches closest to fold-line 14 provide the longest roll and notches closest to fold-line 40 provide the shortest; however, if the notches are too close to fold 40 the rubber band may fail to move at all.
A further manner of varying the tension of rubber band 32 and hence the characteristic of the sound emitted is to vary the length or depth of the notches along these edges. a greater depth than notches 24 and 28. Still another mannerof varying the tension of rubber band 32 is tor make panels 42 and 44 larger soY that fold-line 40 is Ycloser Ito the outer transverse edge of panel 18. However, ifA
panels 42 and 44 are made too large, stiffer material must be Iused -to'pr'event them from collapsing under the inwardl entire rubber band. Notches or cuts were shown for maintaining the rubber band in position during operation. Other means .fori maintaining the band-in position may be'used, such -as fastening therband to the rear surface of panel 18. Also, if Ithe rubber band is not placed in great tension, no specific holding means may be necessary, except possibly roughening the upper and lower edges of the panel, or using varied ridges on the edges.
Whilesound panels 42 and 44 were shown cut fromA panels 20 and 18 respectively, separate sheets of material can be mounted on panels 18 and 20 to fold in a similar manner as panels 42 and Y44.V Also, the sound emitting As shown in FIGURE 2, notches 26 and 30 haveV second and third transverse fold-lines in said first and second panelsV respectively between corresponding ends of said slits, first and second areas in said first and second panels respectively defined by said slits and said foldlines, said first'and second areas foldable away from saidV first and second panels respectively when said card is closed, said first panel having a notch in its upper and lower edges adjacent said first fold-line, and elastic means received in each of said notches and overlying and abutting said first area when the card is in its open position, said elastic means being adapted to be stretched and being juxtaposed along said second fold-line in said first panel when said card is closed, and being adapted to be urged along the surface of said rst area and returning to overlie said first area in response to the opening of said card, whereby said elastic means is vibrated while moving along the surface of said first area in response to the opening and closing of said card and thereby emits sound.
