DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a stringed musical stringed toy embodying the principles and concepts of the present invention and generally designated by the reference numeral 2 will be described.
As best illustrated in FIGS. 1 through 6, the stringed musical toy 2 comprises a housing 4 that is preferably a tapered box having a hollow interior 35. The housing 4 has two ends comprising a wide end 6 and a narrow end 8, with the width of the housing 4 gradually lessening as it traverses from the wide end 6 to the narrow end 8. The housing also has a front panel 19 and a back panel 30. The back panel 30 has a plurality of screw mounts 62 and removably attaches to the front panel 19 via a plurality of screws 64 engaging the screw mounts 62. On the wide end 6, the front panel 19 and the back panel 30 comprise a pair of first ears 37 and second ears 39, respectively, extending outwardly perpendicular to the strings. The pair of first ears 37 and the pair of second ears 39 are vertically aligned. A first pivot slot 22 continuously runs through one of the pair of first ears 37 and one of the pair of second ears 39. A second pivot slot 24 continuously runs through an opposite one of the pair of first ears 37 and the opposite one of the pair of second ears 39. The first pivot slot 22 and the second pivot slot 24 removably receive a bolt 60 to create a pivot point. The dimensions of the housing 4 are preferably a wide end 6 width of about 91⁄2 inches, a narrow end 8 width of about 31⁄2 inches, a length of about 23 inches, and a depth of about 3 inches. The dimensions allow a user to squeeze a pair of levers 26, 28 which pivot from the first and second ears 37, 39.
On either side of the housing 4 are located a pair of levers 26 and 28. Lever 26 is pivotally attached to a first pivot slot 22 between one of the pair of first ears 37 and one of the pair of second ears 39, while lever 28 is pivotally attached to second pivot slot 24 between an opposite one of the pair of first ears 37 and the opposite one of the pair of second ears 39. Each lever 26, 28 provides an arm end 50, 51 respectively and a string bar end 20, 21 respectively, each string bar end 20, 21 having pivot apertures 54, 55 respectively, therein. Each pivot aperture 54, 55 selectively aligns with the first pivot slot 22 and the second pivot slot 24. A bolt 60 removably engages the first pivot slot 22 and the pivot aperture 54 of lever 26, while another bolt 60 removably engages the second pivot slot 22 and the pivot aperture 55 of lever 28. Each arm end 50, 51 terminates in an outwardly turned curve 56 to conform to a user's hand. Normally, the “default” position of each of the levers 26 and 28 are almost parallel to the length-wise dimension of the housing 4. Squeezing either or both of the levers 26, 28 causes the corresponding string bar end 20, 21 to move slightly away from the narrow end 8 thereby increasing tension on the selected strings.
The stringed musical toy 2 has four internal strings 13, 14, 15, and 16 located within the housing 4. The strings are accessible through an opening 18 located on the front panel 19. Each string 13-16 has two ends comprising a first end and a second end. The first end of each string is removably attached to a tuning peg 9-12, respectively. The tuning pegs are associated with the narrow end 8 of the housing 4. A bridge 40 runs continuously across the width of the housing 4 hollow interior 35 near the narrow end 8 between the tuning pegs and the opening 18. The strings 13-16 run continuously from the first end to the second end, crossing over the bridge 40 therebetween.
The second end of each string 13-16 is connected to a string bar end 20, 21 by stringing the string through holes in the string bar end. In use the string bar ends 20, 21 are internally located within the housing 4. A string bar stop 25 limits the movement of the string bar ends 20, 21 towards the narrow end 8 of the housing 4.
Squeezing lever 26 changes the pitch of strings 15 and 16, while squeezing lever 28 changes the pitch of strings 13 and 14. In effect, each of the levers 26, 28 serves as a partial tremolo bar for the two strings that are attached to it, allowing an individual to modify the pitch at will for the attached strings.
The housing 4 also has a back panel 30 that can be removed allowing an individual to access all components within the housing 4.
The stringed musical toy 2 also has an acoustic output jack 32 that is attached to the wide end 6 of the housing 4. The acoustic output jack 32 can be used to connect the stringed musical toy 2 to an external device 34 as needed. The external device 34 can be any one of a wide variety of items, including but not limited to an amplifier, signal processing unit, recorder, or other related items.
Operation:
To use the present string musical toy 2, strings 13-16 must be attached. To attach the strings, a user removes each lever 26, 28 from the wide end 6 of the housing 4. The user then attaches the second end of each string 13-16 with the second end of strings 15 and 16 removably attached to the appropriate string bar end through the string holes. Each lever 26, 28 is then removably reattached to the wide end 6 of the housing. Then, the first end of each string 13-16 is pulled over the bridge 40 and attached to a tuning peg 9-12, respectively. The excess string exits the narrow end 8 of the housing 4. To play the toy 2, a user plucks the strings 13-16 to create notes while squeezing on the levers 26, 28 to selectively change the pitch of the notes played on the strings 13-16.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
