Primary Examiner- Lawrence Charles Assistant E.raminer- Wenceslao J. Contreras Attorney-Howard C. Miskin ABSTRACT: A display device has a pair of panels foldable along a fold line. Portions of each panel adjoining a common section of the fold line are moveable outwardly from the panel during folding. These portions are defined by cuts in the panels which intersect the fold line with other fold lines connecting corresponding ends of these cuts. One of the panels has a layer beneath its corresponding moveable portion. A flexible arm mounted on one portion of the moveable panel slideably rubs the facing surface of the lower layer during opening movement of the panels, thereby emitting a sound.

PATENTEDJULZIIQ?! INVENTUR. CHARLES RLUCHSINGER AT'RDRNIZ Y SOUND-EMITTING DEVICE This invention relates to display devices in general, and more particularly relates to a sound-producing greeting card or greetingcard folder which when folded lies flat and when opened emits a sound ofa predetermined characteristic.

Various attempts have been made to provide display devices, greeting cards or folders which emit sounds and noises in conjunction with the visual presentation normally provided. Heretofore, clickers, Snappers, whistlers and rubberbands had been used with such devices to make noise or sound when actuated in some manner, such as when compressed. However, most of these types of noisemakers are not satisfactory, when used in greeting cards or devices intended to be sent by mail, since they are bulky and ordinarily prevent the greeting card, device or folder from lyingflat when folded,

and also require a heavier paperboard to be'used to prevent the individual sheets from tearing when the noisemakers are operated. Additionally, 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 is limited by the type Of device used and are difficult to incorporate in the card or device. Q

According to the present invention, a greeting card or display device is provided which emits a sound of a predetermined characteristic automatically when the greeting card is opened. The sound emitted is normally of a low pitch and can continue for substantially the duration of the opening operation.

It is an object of the present invention to provide a greeting card made of conventional paper which lies flat when folded and may be inserted in an ordinary mailing envelope and which provides sound when opened without a separate actuating effort by the user.

Another object of the present invention is to provide a greeting card which emits the sound whenever opened or closed and which characteristic of the sound can be easily varied to achieve the desired effect.

Still another object of the present invention is to provide a greeting card or other type of display device which produces sounds of a predetermined characteristic when the device is opened, and which requires no special sound-producing device or special means of mounting the device.

. Yet another 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 and storage.

Other and more detailed objects of the invention will be apparent when the following description is considered in connection with the annexed drawings in which:

' HO. 1 is a perspective, elevational view of a display device in the form of a greeting card containing oneembodiment of the present invention in semiextended position;

FIG. 2 is a fragmentary plan view of the flap construction with a portion broken away to show part of the sound emitting structure;

HO. 3 is a cross-sectional view taken along line 33 of FIG. 2 during the opening ofthe card; 1

FIG. 4 is a view similar to FIG. 3, showing the card in its open position relative to the sound-emitting structure;

FIG. 5 is a plan view of the flap construction similar to FIG. 2 ofa further embodiment; and

FIG. 6 is a cross-sectional view taken along line 6-6 of FIG. 5.

Similar reference numerals in the different views refer to similar elements.

Referring now to the drawings, a device in the form of a greeting card 10 is shown embodying the features of this invention, which is made advantageously from a single sheet 12 of paper, cardboard or the like. Sheet 12 isadvantageously scored, at 14 and 16, so as to divide sheet l2 into four integral panels or sections, 18, 20,22 and 24. As shown, panels 18 and 'are folded about a central fold line 16. If desired, sheet 12 need only have one panel or section of a double thickness. Ordinarily, the top surface of front panel 18 bears various indicia or designs. I I

As shown, panels 20 and 22 have a pair of spaced-apart, longitudinally extending slits or cuts therein, 26 and 28, which intercept a fold 'line 16 and are shown parallel. Disposed between corresponding ends of slits 26 and 28 are transverse scored or fold lines 30 and 32. As shown, score line 30 is in panel 20, and score line 32 is in panel 22. Slits 26 and 28 and fold lines 30 and 32 define an area or flap 34. Flap 34 is divided by a score or fold line 36 into a pair of panels 38 and 40. Fold line 36 is contained within a plane passing through fold line 16 and bisecting the angle formed by panels 20 and 22, and'is parallel therewith.

Mounted on the'inner surface of panel 40 of flap 34 is the sound or noise-making element 42, which is preferably a thin, flexible plastic strip. Asshown, noisemaker 42 has a pair of pointed ends 46 and 48, which extend beyond fold line 32 and engage or touch the inner surface of panel 24.

The card is formed by folding sheet 12 about fold line 14 so that the rear faces of panels 18 and 24 abut the rear faces of panels 20 and 22, respectively. The corresponding rear faces are secured together normally in some convenient manner, such as by placing adhesive therebetween or stapling. When panels 18 and 20, and 22 and 24 are folded as shown in FIG. 1, the panels are of double thickness with a continuous front and rear face. This is desirable since the front face of the card can be fully utilized for printing a message or design or other indicia. While panels 22 and 24 are shown both with a double thickness in view'of the sound emitter 42 being mounted on panel 40, panel 20 need have only a single thickness. If the sound emitter 42 is mounted on panel 38 and engages the rear surface or face of panel 18, then panel 22 need be only single thickness.

Sheet 12 is further folded transversely on fold line 16 so that panels 20 and 22 abut when in the closed position. Panels 38 and 40 are folded outwardly along fold lines 30, 36 and 32, with fold line 36 moving in a direction opposite to fold line 16. When card 10 is folded closed it can be conveniently mailed in a conventional envelope. The rear surface of panel 38 is juxtaposed against the rear surface of panel 40 so that card 10 lies relatively flat in its closed position. In this folded position noisemaker 42 is out of engagement with the inner surface of panel 24. I

When card or folder 10 is unfolded to the position shown in FIG. 1, panels 38 and 40 of flap 34 are drawn inwardly toward panels 20 and 22 respectively. With panel 40 being moved toward panel 22 the tooth edges 46 and 48 are flexed and moved along the inner surface of panel 24 away from fold line 16, in the direction of arrow 50, as illustrated in FIGS. 3 and 4. The rubbing movement of teeth 46 and 48 of element 40 across the surface of panel 24, during the normal card unfolding process provide a relatively low-pitched, intermittent sound much like the squeaking of an unoiled door. The sound has characteristics which can be determined in part by the size and material of strip 42. and the type of materiaLwhich it engages. The sound is continuously emitted during the movement of strip 42 until the teeth no longer engage the surface of panel 24 somewhere where the card is substantially open.

In refolding card 10, panels 38 and 40 move outwardly and teeth 46 and 48 of strip 42 move in a direction opposite to that shown by arrow 50, and the panels and strip 42 assume the position of the originally closed position. Teeth 46 and 48 in moving along the surface of panel 24 again emit a sound or noise and the card is again in condition for emitting a sound automatically when the card is opened.

In the embodiments shown in material, which 5 and 6 a serrated, grooved or notched strip 54 is attached to the rear surface of panel 24, so as to be engaged by the free edge of sound emitter 56 mounted on the rear surface of panel 40. As shown in FIG. 5, strip 56 has a single pointed edge 58 which engages the serrated or groovedstrip 54. With the use of a grooved strip 54, a different, more intermittent sound is obtained.

While sound emitter strips 42 and 56 were indicated as made of plastic they may be made of other materials including cardboard, paper or the like. They may be fastened or attached to panel 40 in any convenient manner, and have various shapes and forms. While pointed edges are'shown, flat edges may be used.

While panels 38 and 40 of flap 34 were shown cut from panels and 22 respectively, a separate sheet of material can be mounted on panels 20 and 22 to fold in a similar manner as panels 38 and 40. With this construction only a single thickness of panels 20 and 22 need be used. With the flap formed of a separate strip, the flap could be folded inwardly when the card is closed and move outwardly when the card is opened to emit sound. Also, the sound emitter member 42 and 56 were shown mounted on rear panel 22, but it could be easily mounted on front panel 20. A strip 54 could be made of plastic, cardboard paper or the like.

While the embodiments disclosed in the drawings show the slits being parallel and transverse to the fold line 16, the slits in panels 20 and 22 can be at varying angles to each other and to fold line 16, and which intersect at fold line 16. Similarly, the lower slits in each panel, indicated at 28, could be at different angles with respect to the upper slits, as well as to the slits in panels 20 and 22, whereby flap 34 can take varying shapes. Further, flap 34 can have various fold lines so as to assume different shapes during the opening and closing of panels 20 and 22.

There is thus shown a greeting card or display devicewith an outside face provided with a 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 folded position in an ordinary and conventional type of envelope. The. sound-producing member is inexpensive, and durable in storage, easily mounted during the fabrication of the card, and requires no special further acts of the receiver to actuate.

' It has been found that if the panel against which the sound actuator acts is glued to its facing panel, different pitch sounds are produced depending on the degree of attachment. The combined panels act as a larger sounding board and produce a deeper sound. If the panels are not joined, i.e., panels 22 and 24, the sound pitch emitted during opening and closing the card will vary depending on how the card is held during openmg. I

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.
