Abstract
A double chambered bassboard housing for electronic M.I.D.I. accordion incorporating a folding control panel and a retractable keyboard. In a fully open position the instrument, because of its light weight and curved contour, is ideal to play and to perform with. Furthermore, all the push buttons on the folding control panel (in a fully open position) are readily identifiable because well within the view field of the accordionist. In a fully closed position the instrument becomes even more compact and therefore extremely portable for any mode of transportation.
Claims1
A double chambered bassboard housing for electronic M.I.D.I. accordion with retractable keyboard housing and with a folding control panel;
- said retractable keyboard housing consisting of a standard electronic M.I.D.I. accordion keyboard having a longitudinal outer edge and a longitudinal inner edge;
- said keyboard extending, lengthwise, from said longitudinal inner edge into a short rectangular housing comprising a top and a bottom narrow surface and a front and a back surface;
- said back surface having a leftmost and a rightmost longitudinal edge;
- said short rectangular housing containing in mid section a double-sided front-lateral semicircular access hole large enough to allow a coiled wire to move freely within said semicircular access hole, and said retractable keyboard housing also incorporating a top and a bottom tee-nut imbedded in a far left portion of said top and bottom narrow surface, and said rightmost edge of said back surface containing right above mid point one of two attachments supporting a single back strap;
- said double chambered bassboard housing consisting of a rear chamber and a front chamber internally separated by a solid rectangular partition containing a circular perforation large enough to allow a coiled wire to extend and retract freely within a circumference of said circular perforation and a second smaller cavity accommodating a central wiring of said double chambered bassboard housing;
- said solid rectangular partition having a longitudinal rightmost edge, a longitudinal leftmost edge and a shorter top and bottom edge;
- said double chambered bassboard housing comprising a top and a bottom surface, a rear surface, a left side panel, an outwardly slanted rectangular left front panel having a left and a right longitudinal edge, said right longitudinal edge merging, lengthwise, with one of the two longitudinal edges of a half inch wide surface facing laterally and the second longitudinal edge of said half inch surface merging with one of the two longitudinal edges of a recessed narrower, inwardly slanted rectangular right front panel;
- said right front panel's second longitudinal edge merging with said solid rectangular partition's rightmost longitudinal edge;
- said solid rectangular partition's leftmost longitudinal edge joining, lengthwise, the mid section of said left side panel's inner surface of said double chambered housing and the remaining shorter top and bottom edge of said solid rectangular partition joining with a mid section of the inner surface of said top and bottom surface of said double chambered housing;
- said double chambered housing consisting of a left front chamber, a narrower right front recessed, inwardly slanted surface containing said folding control panel, and a larger rear chamber;
- said left front chamber containing a electronic bassboard mechanism and said narrower inwardly slanted recessed right front panel providing a right amount of recessed area for said folding control panel to rest on and swing out from by means of hinges connecting one of the two longitudinal edges of said folding control panel to said half inch wide surface;
- said hinged longitudinal edge of said control panel and said half inch wide surface both containing, about mid section, one small perforation facilitating the electronic connection of said folding control panel to both said bassboard mechanism and said keyboard housing by means of small wires;
- said folding control panel incorporating a machine screw-like locking apparatus interlocking with a matching tee-nut imbedded directly below in said narrower, inwardly slanted right front panel's surface;
- said rear chamber comprising a rectangular back surface containing the main plug in the lower left corner and containing the second one of the two attachments supporting said single back strap, in the top right corner, a left side surface consisting of the rear longitudinal half portion of said left side panel of said double chambered bassboard housing and a front panel consisting of said solid rectangular partition, a top and a bottom panel consisting of the rear half portion of said top and bottom surface of said double chambered bassboard housing, and a fully open rectangular right side;
- the far left portion of said top surface of said rear chamber containing a regulator of the bass strap, and said open rectangular right side functioning as a receiving conduit within which said rectangular keyboard housing retracts and extends;
- said top and bottom surface of said rear chamber each incorporating a straight cut in the form of a carved-out narrow linear guiding track;
- said rectangular keyboard housing's degree of mobility within the limits imposed by said rear chamber's top and bottom linear guiding track being governed by a top and a bottom flat round knob with machine screw stem passing through said top and bottom linear guiding track and interacting with the respective top and bottom tee-nut imbedded in the far left portion of said top and bottom narrow surface of said rectangular keyboard housing's brief extension;
- by means of a coiled wire passing through said solid rectangular partition's circular perforation and through said rectangular keyboard housing's double-sided front-lateral semicircular access hole, constant electronic contact is maintained between said rectangular keyboard housing and said double chambered bassboard housing.
