The core may include wall portions defining the recess and the spaces between the wall portion and the cover may be filled with polyurethane foam. The cover may be moulded in plastics material and the core may be metal. The controls may be provided in a module which fits in a further cavity formed in the core.
The neck portion may also comprise a metal casting and is preferably such a casting having a wooden fretboard secured thereto. The strings are preferably secured at one end to a bridge carried by the neck portion and at their other ends to machine heads by means of which the strings may be tuned in known manner.
The releasable interengaging means preferably comprises a pair of opposed keyways formed in one of the recess in the body portion and the engageable end of the neck portion and a corresponding pair of keys provided on the other of said recess and end. A spring loaded catch may be provided for retaining the body portion and neck portion in assembled relation.
A preferred embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings in which: Figure 1 is a plan view of a guitar according to the invention;
Figure 2 is an exploded view similar to Figure 1;
Figure 3 is a plan view of a component of the neck portion of the guitar in Figure 1;
Figure 4 is an exploded elevation view of the neck portion;
Figure 5 is a plan view of a core component of the body portion of the guitar of Figure 1;
Figure 6 is a section through the body portion showing the component of Figure 5 assembled with other component 3; Figure 7 is a plan view similar to Figure 5 and showing a modified core component of the body portion, and
Figure 8 is a plan view of a cover component of the body portion.
Referring first to Figures 1 and 2, an electric guitar generally indicated by 10 consists of two main parts, a body portion 11 and a neck portion 12.
The body portion 11, which will be described in more detail below, carries all the usual controls for an electric guitar as indicated at 13. These controls may include a volume control, a tone control, a switch for selecting the various pickups of the guitar, an overdrive preamplifier and its control, an echo delay control, an echo feedback control and appropriate on/off controls. The body portion also includes an elongate recess 1 5 of rectangular cross-section which has keys 1 7 projecting from its side walls (see Figure 3).
The neck portion 1 2 has one end portion 1 8 shaped to be a close sliding fit in the recess 1 5 and includes keyways 1 9 which engage the keys 1 7 to align the neck portion in the recess 1 5 when it is slid into place and to retain the neck portion in aligned reiationship with the body portion.
The end portion 1 8 of the neck portion 12 has mounted on its upper surface a bridge 21 (which includes a tremolo device 22) and three electromagnetic pickups 23. The other end portion 24 of the neck portion 12 is shaped in conventional manner and includes a number of machine heads 26 equal to the number of strings to be fitted to the neck portion. A fretboard 27 of conventional design and made of rosewood, maple or any other suitable wood is fixed to the neck portion 12 between the two end portions 1 8 and 24. Guitar strings 28 extend along the length of the neck portion 12 and are fixed at one end to the bridge 21 and at their other ends to respective machine heads 26. The machine heads are used to tighten and tune the strings in known manner.
It will be appreciated that because the neck portion 12 carries the bridge 21, electro-magnetic pickups 23, machine heads 26 and the strings 28 of the guitar, the strings may be tuned before the neck portion 12 is inserted into the body portion
11 of the guitar. Thus, it will be seen that a user of the guitar may have a single body portion 11 and a number of neck portions 12, each neck portion having a number of strings 28 and being tuned in a particular way for a different purpose. For example, the user may have neck portions with six strings in standard or open tuning, with twelve strings in standard or open tuning or with four strings as a bass guitar.
The details and construction of the neck portion 1 2 of the guitar will now be described in more detail with reference to Figures 3 and 4.-The basic component of the neck portion 12 is a metal casting 30 which has the shape shown in Figure 4 and may be of magnesium alloy, aluminium or other suitable metal. Magnesium alloy is the preferred material.
The end portion 1 8 of the casting includes recesses 31, 33 arranged and shaped to accommodate the bridge 21 and pickups 23 of the guitar. The end portion 24 includes holes 36 which are provided to accommodate the machine heads 26. The central portion 37 of the casting between the two end portions includes two channels 38 running down the length of the central portion to reduce the weight of the casting. The fretboard 27 corresponds in shape to the central portion 27 of the casting 30 (Figure 3) and is secured to the casting 30 by suitable means such as glueing and screwing. The keyways 19 are machined into the end portion 1 8 of the casting and may be treated to reduce wear, for example, by chrome plating.
The construction of a first embodiment of the body portion 11 of the guitar will now be described in more detail with reference to Figures 2,5 and 6. The body portion 11 comprises a core 60 (Figure 5) surrounded by a cover 61 (Figure 6).
The core 60 is a metal casting which is preferably of magnesium alloy but may be of other suitable metals, for example, aluminium.
The core 60 comprises a base portion 66
including a plurality of holes 62 and, upstanding from the base portion, wall portions 63, 64 which together define the recess 1 5. Keyways are machined into the wall portions 63 after casting and the keys 17 are fixed into those keyways. Two further wall portions 65 extend from the free ends of wall portions 63 to define the front edge shape of the body portion 11.
The cover 61 is a moulded shell of plastics material which is shaped to provide the finished shape of the body portion 11 (Figures 2 and 6).
The cover 61 fits around the core 60 and edge portions of the cover are secured to the upper edge of wall portions 63, 64, 65 of the core 60.
The cover 61 includes a cavity 67 for the controls 13.
When the core 60 and cover 61 are assembled together as shown in Figure 6, the spaces between the cover and core are then filled with polyurethane foam 68 which is injected into the spaces.
Located within the recess 1 5 in end wall portion 64 of the core is one part 48 of a multipin-connector.
The other corresponding part 49 of the connector is provided in the end of the portion 1 8 so that when the neck portion 12 is engaged with the body portion 11 of the guitar the two parts of the connector 48, 49 interengage
The controls 13 and their corresponding circuit components are provided in a module 51 which fits into the recess 67 and has connections from the controls 1 3 to the connector 48.
The other connector part 49 is connected to the pickups 23 so that when the neck portion 12 and body portion 11 are interengaged, the pickups 23 are connected to the controls 13. An outlet socket is also provided on the module 51 for connecting the guitar to an amplifier in known way.
As described above, the neck portion 12 is a close sliding fit in the recess 1 5 and the body portion 11 but to ensure that the neck and body portions do not move relative to each other, a locking catch 70 (Figure 2) is provided. The locking catch 70 comprises a catch 71 pivoted on a support 72 fixed to the outside of the wall portion 64 of the core. A housing 73 fixed to the inside of the wall portion 64 contains a spring (not shown) urging the catch into its locking portion. A recess 75 in the end of the body portion 11 allows access to the free end of catch 71 for manual operation. A hook 76 fixed to the end of portion 1 8 of the neck portion of the guitar engages the catch 71 when the neck portion is slid into the recess 1 5 to lock the neck and body portions together.When the neck portion is to be released, the catch is operated manually by moving the free end to the left as illustrated in
Figure 2.
Referring now to Figures 7 and 8, a second embodiment of the body portion 11 is illustrated, which comprises a core 40 (Figure 2) and a cover 41 (Figure 8).
The core 40 (Figure 7) is an aluminium casting having the shape shown in Figure 7 and includes the recess 1 5 which is machined to size so that the end portion 18 of the neck portion 12 of the guitar is a good sliding fit in the recess. Two keyways are also machined into the sides of the recess 1 5 and the keys 17 are fixed into these keyways. The core 40 also includes an elongate cavity 42 and a number of cavities 43. Edge portions 44 of the core 40 extending along the sides of the recess 1 5 project from the remainder of the core and are polished to provide fingerplates.
The cover 41 (Figure 8) is a shell of polyester resin impregnated fibreglass which fits over the core 40 as shown in Figure 9. The cover 41 is shaped to provide an aperture 46 edges of which engage the core 40 under the edge portions 44 around the recess 1 5 and an aperture 47 which corresponds in shape to the cavity 42 in the core.
When the core 40 and cover 41 are assembled together the cavities 43 are then filled with polyurethane foam which is injected through holes in the core which are subsequently plugged.
Located within the recess 1 5 at its end, is one part 48 of the multi-pin connector which connects with the other part 49 as described above.
To lock the body portion 11 to the neck portion 12, a locking pin 52 of the spring loaded zeus type is provided which is located through a hole 53 in the core 40 and locks into a recess (not shown) in the neck portion 12.
It will be appreciated that the invention is not limited to the preferred embodiments described above and various modifications may be made within the scope of the invention. For example, the neck portion 12 may be shaped and include appropriate stringing to provide a variety of stringed musical instruments in addition to the range of guitars described above. These may include a mandolin, banjo, lute or other strung fretted instruments.
The guitar 10 described above has a number of advantages over conventional guitars constructed from a wooden body an an integral wooden neck.
First, as described above, the provision of the neck portion 1 2 carrying the strings and the necessary means to tune the strings means that a numer of pretuned neck portions may be provided which may be readily and rapidly interchanged with the body portion. Second, the construction of the neck portion from metal and the body portion from a metal core with injected polyurethane foam and a fibreglass or plastics cover improves the "sustain" of the guitar, that is to say the tonal quality of the notes produced is improved.
