(9) FIG. 8 shows schematically a top view of the handpull musical instrument according to FIG. 7.

(10) As shown in FIG. 1 and FIG. 2, the invention relates to a handpull musical instrument, in particular an accordion, with housing parts for treble, the treble housing 2, and bass, the bass housing 3, connected by a bellows 1. Moreover, the handpull musical instrument comprises the associated sound and/or signal producing equipment and mechanical parts (not shown). A treble keyboard 4 is installed in the treble housing 2 and a bass keyboard 5 is installed in the bass housing 3.

(11) The treble housing 2 is configured as an columnar hollow body 6 in angular design, which is open on the bellows side and opposite thereto comprises an opening 7 for receiving a treble cover 8. The treble cover 8 is arranged so as to be aligned at an acute angle to an instrument central plane M between the two housing parts 2, 3, such that the treble housing 2 is tapered towards the instrument front face V and, thereby, the treble cover 8 is displaced towards the front. The treble cover 8 forms the treble keyboard 4. The treble keyboard 4 thus preferably closes the opening 7 of the columnar hollow body 6 in angular design and is thus integrated within the spatial shape of the treble housing 2. The treble housing 2 delimits, via the columnar hollow body 6 in angular design, a space 9 (see FIG. 4) which is suitable for accommodating the sound and/or signal producing equipment, valves, key mechanisms, etc.

(12) The treble keyboard 4 is preferably arranged at such a distance from the bellows 1 that an arrangement plane D of the treble cover 8 passes through the instrument central plane M outside the instrument's base area. The treble keyboard 4 is preferably arranged in an angular range of 30 to 80 relative to the instrument central plane M.

(13) The columnar hollow body 6 in angular design preferably has a cross section of a triangle or convex quadrilateral or pentagon, whereby the treble keyboard 4 displaced towards the front is orientable relative to the instrument central plane M at angles which take account of human anatomy and at the same time provide a hollow body 6 with sufficient dimensions for accommodating the sound and/or signal producing equipment. In the first exemplary embodiment shown in FIG. 1 and FIG. 2, the cross section of the columnar hollow body 6 in angular design of the treble housing 2 is substantially triangular with one side toward the bellows 1, one side toward the rear face 12 of the handpull musical instrument and one side toward the treble keyboard 4. The side surface 14 and the remaining side surfaces of the columnar hollow body 6 in angular design may be configured to be planar, curved and/or cornered.

(14) The treble keyboard 4 and the bass keyboard 5 may be configured as a piano keyboard or a button keyboard. FIG. 1 and FIG. 2 show the treble keyboard 4 as a piano keyboard according to a first exemplary embodiment. The treble keyboard 4 in this case preferably has a vertical keyboard axis. As FIG. 1 and FIG. 2 also show, the bass keyboard 5, for example, has a button keyboard.

(15) The treble housing 2 may be provided for delimiting a space 9 for accommodating reed blocks 10 bearing bellows-actuated reeds (see FIG. 7). In a preferably mechanical acoustic accordion the keys 11 of the treble keyboard 4 are connected to treble valves (not shown) which, actuated by bellows, control in a manner known per se the air flow through reed blocks 10 bearing the different reeds. Alternatively or additionally, the keys 11 may be provided individually with switches and/or contacts, etc. which serve for the individual control of electrical sound signal sources. These switches and/or signal producing equipment are known per se and are not shown.

(16) A polyphonic electrical sound and/or signal producing equipment, which is known per se, together with the associated electronic components may be accommodated in the treble housing 2 according to the invention.

(17) In the second exemplary embodiment shown in FIG. 3 to FIG. 5, the above applies accordingly. As in particular FIG. 4 shows, the columnar hollow body 6 in angular design is configured in cross section according to a convex quadrilateral and the width of the front side surface 14 is selected such that together with the tapering of the hollow body 6 and thus the angular alignment of the treble keyboard 4 relative to the instrument central plane M a spatial depth for the treble housing 2 is achieved which accommodates the sound and/or signal producing equipment and associated components, in particular when electronic sound and/or signal producing equipment is installed at the same time. The treble keyboard 4, however, is to be played in the same manner as in the first exemplary embodiment since the angular position relative to the instrument central plane M is selectable in the same manner.

(18) As FIG. 4 in combination with FIG. 5 shows, the treble keyboard 4 is insertable into the opening 7, wherein the treble keyboard 4 has a number of sound outlet openings 15 for the air flowing through bellows-actuated reeds (not shown) for the production of sound. The sound outlet openings 15 may be configured in a region around the treble keyboard 4. When the treble keyboard 4 is configured as a piano keyboard as shown in FIG. 5, each key 11 is preferably configured with a sound outlet opening 15 along the edge 16 of the hollow body 6. The edge 16 is preferably arranged on the front side surface 14 of the hollow body 6. The keys 11 may have, for example, an extension portion as shown in FIG. 5, the respective sound outlet opening 15 being formed therein. As a result, a bar consisting of a plurality of sound outlet openings 15 can be provided. The width of the respective sound outlet opening 15 in this case may follow the width of the respective key 11 of the piano keyboard. The bass keyboard 5 may be configured in the same manner with a number of sound outlet openings (not shown).

(19) FIG. 6 shows a third exemplary embodiment which differs from that shown in FIG. 3, by the treble keyboard 4 being configured as a button keyboard. Otherwise, the above-described applies accordingly.

(20) As shown in FIG. 7, for example, the bass housing may have a fingerboard 20 for bass buttons 21, the handle level thereof being at an angle relative to the instrument central plane M. According to an exemplary embodiment, not shown, the handle level B of the bass buttons 21 may be arranged mirror-symmetrically to the treble keyboard 4. Moreover, FIG. 7 shows, via a cut-out, partial regions of a mechanical sound producing equipment in the treble housing 2.

(21) FIG. 8 illustrates by means of a via top view of the handpull musical instrument according to the invention, in particular the accordion, the orientation of the treble keyboard 4 on the treble housing 2 relative to the front face V and rear face 12 of the instrument relative to the instrument central plane M.

(22) According to an exemplary embodiment, not shown further, the treble cover 8 may be of roof-shaped configuration, wherein the treble keyboard 4 is preferably arranged on the roof side, that is directed towards the front face V of the instrument.

(23) The treble cover 8 forms the treble keyboard 4 according to the invention, wherein the sound and/or signal producing equipment as part of the inner mechanical structure of the instrument is positioned physically close behind the treble keyboard 4, as shown in particular in FIG. 7 in conjunction with FIG. 8. The treble keyboard 4 thus forms an upper shed having an overlap with a subjacent lower shed in the form of the space 9, in which the sound and/or signal producing equipment, as in particular the reed blocks 10 according to FIG. 7, are arranged. The overlap is a lateral overlap with respect to an instrument central plane M (FIG. 8), wherein the overlap may be chosen to have a partial or full overlap range. The upper and lower sheds are then preferably aligned in relation to the bellows 1 of the handpull musical instrument. The shed height of the lower shed, or space 9, may be determined by a width of the front side surface 14 of the columnar hollow body 6 in angular design (FIG. 4).

(24) Finally, according to the invention, the use of the above-described handpull musical instruments, as an accordion or other accordion type, chromatic or diatonic, is intended.

(25) All publications and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.

(26) The invention now being fully described, it will be apparent to one of ordinary skill in the art that many changes and modifications can be made thereto without departing from the spirit or scope of the appended claims.
