  • Latch 10 comprises a guitar body base plate 12 which is secured to the body 14 of a guitar ( Figure 5) by screws 19, which are secured in holes in guitar body 14.
  • Base plate 12 includes integral upstanding walls 16. Walls 16 include holes 18 which support short pivot pins or screws 20. Screws 20 screw into the threaded holes 18, and fit into holes 24.
  • Latch arm 22 rotates on the end of screws 20.
  • latch arm 22 (which includes holes 24 which receive screws 20) is rotatably mounted on pivot pin 20.
  • a hitch arm 26 comprises a base 28 which defines a hole 30.
  • a pin 32 is mounted in hole 30 in hitch arm 26 and hole 34 in latch arm 22. This allows for rotational movement between hitch arm 26 and latch arm 22.
  • the distance by which the ball 36 is positioned with respect to the end of base 28 is adjusted by screw arm 38, by rotation of screw arm 38 which is screwed into a tapped hole 40 in base or hitch body 28.
  • the rotary position of screw arm 38 may be locked by rotation of nut 42.
  • Nut 42 rotates on threads 43. It is noted that threads 43 also mate with tapped hole 40.
  • Ball 36 engages a socket 44 in heel catch plate 46 at an arc shaped engagement surface 48.
  • the structure of the hinge is completed by a spring 50 which is mounted in tension between a hook 52 on hitch arm 26, and a hook 54 on guitar body base plate 12.
  • latch 10 takes the position illustrated in the solid lines, with heel catch plate 46 mounted in folding guitar neck 56 by screws 57. If it is desired to put the guitar in the travel position, it is folded about hinge 58 in the direction of arrow 60. In order to do this, it is necessary to release latch 10. This is done by pulling latch arm 22 to the position illustrated in phantom lines in Figure 5. This is facilitated by tapered surface 62 which allows the user to insert a fingernail to pull latch arm 22 out in the direction of arrow 64. This also allows ball 36 to be moved in the direction of arrow 64 and exit heel catch plate 46.
  • latch 10 is much like a Visegrips brand locking pliers. More particularly, in the position illustrated in broken lines in Figure 5, pin 32 is relatively far from arc-shaped engagement surface 48. When the center of pin 32 passes over the center line 66 of screw 20, pin 32 is closer to engagement surface 48. It is then so close to engagement surface 48 that significant pressure is exerted between ball 36 and engagement surface 48. As pin 32 continues to the position shown in solid lines in Figure 5, this pressure is somewhat reduced as the distance between pin 32 becomes somewhat larger again. Thus, the latch securely joins neck 56 to body 14, and is held in that position because the tension acting on screw arm 38 tends to pull neck 56 toward body 14.
  • FIGS. 6- 21 another embodiment of the hinge is illustrated. This embodiment operates much the same way as the embodiment of Figures 1-5, and analogous or corresponding parts are labeled with numbers 100 higher than the numbers of the corresponding or analogous parts in the embodiment of Figures 1-5.
  • latch 110 comprises a latch arm 122 mounted for rotation on screws 120 which pass through tapped holes 118 in latch plate 112. The ends of screws 120 extend into holes 124 in latch arm 122 to support latch arm 122 for rotation with respect to latch plate 112.
  • Pin 132 is jam fitted into hole 130. The ends of pin 132 extend into and are loosely fitted to holes 134 in latch arm 122. A pair of balls 168 are received within hole 170 at opposite ends of hole 170. A coil spring 172 is held in compression between balls 168. In the position where latch arm 122 is parallel to latch plate 112 and flush with latch plate 112, balls 168 are driven toward holes 124, thus positively locking latch arm 122 in place.
  • a leaf spring 150 is secured to hitch body 128 by a bolt 152, which screws into hole 174 in hitch body 128.
  • leaf spring 150 urges ball 136 away from latch arm 122, facilitating folding of the guitar neck.
  • Hitch arm 138 passes through hole 177 in hitch body 128. Rubber washer 145, washer 143 and locking nut 142 are mounted on the end 176 of hitch arm 138. When latch arm 122 is flush with latch plate 112, latch arm 122 pulls the end 176 of hitch arm 138 together with rubber washer 145, washer 143 and locking nut 142 toward heel catch plate 146.
  • Rubber washer 144 acts like a spring to apply a locking force. This results in an exertion of force without applying that force to the wood surrounding the screws which are used to secure the latch to the guitar body and neck. More particularly, screws, not illustrated, pass through holes 178 in heel catch plate 146, and holes 180 in latch plate 112.
  • hitch arm 138 Excess movement of hitch arm 138 is limited by skirt 182. The movement of hitch arm 138 is limited by locking cap nut 142, which when the latch is opened, is caused to bear against spring pin 184, which is mounted in holes 186 in perpendicular extensions 188 of latch plate 112.
  • a guide 191 includes a guide surface 192 which guides the exit of hitch arm 138 from heel catch plate 146 during folding of the guitar neck. Holes 193 receive the same screws as holes 180 illustrated in Figure 6. If desired, guide 191 and heel catch plate 146 may be cast as a single part.
  • Latch 210 comprises a latch arm 222 mounted in a latch plate 212.
  • a ball 236 mounts in a heel catch plate 246.
  • a sliding latch lock 294 is mounted in a slot 295, within which it slides. In the position illustrated in Figure 22, latch lock 294 overlies latch arm 222, thus positively retaining latch arm 222 in the locked position.
  • Rivet 296 is secured to lock 294 and maintained in slot 295 by a washer 297.
  • the manufacture of a guitar 310 in accordance with the inventive process may comprise the separate manufacture of a body 312 and a neck 314. While the method is illustrated in connection with an acoustic guitar, the process steps involved may be employed in the manufacture of an electric guitar.
  • the traveling guitar 310 may be reduced in size for travel by hingedly advancing neck 314 in the direction indicated by arrow 316, as shown in Figure 26. The result is for neck 314 to overlie body 312 as illustrated in Figure 27.

  • the neck 314 of the guitar is manufactured as a single piece, pocket 318 is then cut into the neck and a hole for a reattachment device is drilled through the heel of the neck.
  • Pocket 18 is preferably routed before a fingerboard is attached and before a neck separation cut is performed.
  • the position of the separation cut may be marked by a line, for example line 322 drawn in pencil as illustrated in Figure 28.

  • a circular saw is used to make the separation cut along line 322 to cut away an amount of wood which results in a tight fit between hinge 320 and pocket 318. Cutting of the separation cut is done along the line 322, with the saw positioned in a plane which is, for example, perpendicular to the central axis of fingerboard 326.

Abstract

L'invention porte sur une guitare pliable, qui comprend un corps et un manche. Une articulation relie le corps au manche, et est disposée sur un côté du corps et du manche. Une plaque de verrouillage est fixée sur un côté et un loquet est fixé sur l'autre côté. Le loquet définit une surface d'encliquetage. Un bras de verrouillage est monté de façon à pouvoir pivoter sur la plaque de verrouillage. Un bras d'accrochage est monté de façon à pouvoir pivoter sur le bras de verrouillage. Un élément de fixation monté sur le bras d'accrochage est configuré de façon à venir en prise avec la surface d'encliquetage du loquet. Le bras de verrouillage, le bras d'accrochage et la plaque de verrouillage font varier la distance entre l'élément de fixation et la surface d'encliquetage du loquet. Une poche de réception d'articulation est découpée dans le manche. Un premier trou est percé dans la base du manche de guitare pour une fixation du manche et un second trou est percé pour recevoir un mécanisme d'alignement. La poche, le premier trou et le second trou sont divisés après fixation d''un clavier.
