Description

    The present invention relates to a folding guitar provided with a position locking mechanism.

    Manufacture of musical instruments that produce sound began as a search for the possibility of mechanically producing the same thing as a human voice. This was in fact the standard throughout the Middle Ages and until the Renaissance and modern times.

  Stringed instruments have been known since ancient times. These include instruments such as guitar-like instruments with a lute, resonant drum and fingerboard. The bronze of the New Dynasty (Ancient Egypt, 1380BC) of the Metropolitan Museum of Art depicts a Nubian who bends one knee and stands on toes, the left hand is busy moving on the fingerboard, and the right hand is dancing with strings The pose seems to depict a modern rock musician.

  However, the lute has a much older history, probably originating from the non-residents of West Sem who brought instruments to Mesopotamia, and the mid-dynasty Hyxos dynasty (XV-XVII dynasty, 1730-1580B. It was reported to the Egyptians at the end of C.). Mesopotamian archaeological records have depictions dating back to the Akkadian period (2350-2170 BC).

  In a closer era, lute-like stringed instruments continue to be the most popular instruments. Folk artists throughout the United States use a wide range of musical genres, including blues and bluegrass, sometimes using handmade guitars.

  In contrast to percussion instrumentation, the need to amplify the relatively weak sounds of strings, reeds, and vibrating human lips has been a challenge for early instrument manufacturers. These issues were mainly addressed by the resonance system. A resonance system mechanically collects, concentrates, and outputs musical sounds. When producing high sound quality, there are strict standards for instrument stability.

  In addition, over the years, artists playing acoustic stringed instruments have incorporated a wide range of playing techniques into the music surrounding these instruments. Perhaps the ancients only got a musical tone by flipping the lute strings, but the musical tone gradually faded, while more recent artists used bows to produce a relatively constant and somewhat controllable amplitude sound. Produced. Modern artists use a variety of techniques when performing. Acoustic blues players may tap the instrument with their fingertips, palms or finger joints. Some violin tunes that are generally played by sliding a bunch of horse hair on a string also require that the string be repelled. This further increases the demand for mechanical stability of the instrument.

  Given the popularity of stringed instruments, especially guitars, there are many people who bring their instruments when traveling. However, stringed instruments are bulky and not very suitable for easy transportation. Stringed instruments will not fit under the airplane's luggage space or under the airplane's seat. In response to this demand, a guitar with a folding neck has been proposed. For example, US design patent No. 516,114 of the applicant's earlier application and US patent application No. 11 / 640,095 (filed on December 15, 2006) of the applicant's earlier application are pending. See While this instrument is effective, it is difficult to make the necessary important handwork and fine adjustments.

    Thus, stringed instruments such as guitars and violins that are easy to perform during performance should be consistent, accurate and easily transportable when converting artistic interpretations to acoustic or other performances. . The structure disclosed herein is considered to be the most effective solution to provide a highly mobile instrument that can be accepted in a variety of user performances.

  The present invention also relates to hinges and, in particular, to what is commonly known as a hidden hinge used in connection with doors and other swinging articles, the invention described herein is a hinge. The surface available for the mechanism is very narrow and the hinge is an improvement over conventional designs for special applications that need to be able to support a relatively long vertical surface. Important to the present invention is the method used to place and mount the hinge.

  In this type of hinge, the hinge portions are connected by a rotary linkage. The linkage is hinged to a hinge pin, slides over the slide pin, and is in a pocket or compartment in the hinge portion that is a hinge plate or butt plate. An early version of such a hinge is the hinge design produced by Joseph Soss and named after him. In particular, U.S. Pat. Nos. 1,030,936, 1,484,093, 1,688,996, 1,984,092, and Illustrated in several patents, including 2,178,271. This type of hinge is also used in the aforementioned design patent.

  These hinges are designed to be hidden when in the closed position, with the central portion of the hinge below the surface when in the closed position, and extend from the surface so that it can be fully opened 180 degrees. The two basic versions of the hinge are common. The first has an elongated body with two mounting screws, one at each end. This type is a shape that requires multi-level mortise cuts for mounting. The second is a cylinder hinge or barrel hinge with a screw attached to the side as an attachment part, and it is necessary to make a hole for mounting.

  These previous designs are of similar nature, but they lack the necessary clearance, are either inadequate or impractical for a guitar with a foldable neck, and are also hinged A complicated process is required to make an opening in the butt plate or cylinder.

  Furthermore, although it has been found that conventional design versions can support this application of the above-mentioned US design patent D516,114 to some extent, in some areas it is less efficient than a small shop that is hand-assembled. Has been found to be lacking in production.

  First, these hinges, known as “barrel hinges”, require a final outer surface (eg, instrument fretboard) to be mounted out of the normal sequence of production procedures, and on the surface of the fretboard. It is necessary to make a hole that weakens this important structural member in order to get very close.

  Second, these hinges are very difficult to set accurately with respect to depth and alignment. Other versions of Soss hinges have better securing means and better placement and depth control. However, the design can only fit a single hinge in the desired area, lacks structural integrity in this application, and does not have sufficient ability to properly align the two hinge portions. Moreover, the location of the fixing screw is very close to the outer edge of the member, which causes problems in this application because the screw materials themselves are not properly fixed. Currently available versions also lack the opening clearance required for guitar hinge applications. Finally, the means required to cut the mortise is very time consuming and difficult to achieve stably.

    According to the present invention, a stringed instrument includes a neck extension primary member having a neck extension fixed end and a tuning assembly support head end, an extension upper part, and a full length part extending between the ends. Is provided. The neck extension primary member defines a neck extension cut-off volume, which is configured to receive a hinge butt.

The neck base primary member includes a neck base fixed end, a base upper portion and an opposing end. The neck base primary member is fabricated to define a neck base cut-off volume, which is configured to receive a hinge bat. The neck base truncation volume extends so as to open at the neck base fixed end and open at the top of the neck base primary member. The hinge has a first hinge butt positioned in the neck extension cut volume and a second hinge butt positioned in the neck base cut volume. A neck fretboard portion is fixed to the open upper portion of the neck extension portion cut-off volume portion, and supports the first hinge bat. A base cover is fixed to the open upper portion of the neck base cutout volume, and supports the second hinge butt. The main body of the stringed instrument is fixed to the neck base primary member.

  Two or more Soss link assemblies are connected to a single pair of hinge bats, each bat defining a pair of Soss hinge link receiving races, and a pair of spaced Soss formed on a single pair of hinge bats. A hinge assembly is formed.

  Each hinge bat defines a fixed screw receiving hole that is oriented to extend the entire length of the stringed instrument neck.

  As shown in FIG. 5, the neck 12 is attached to the guitar body 14 by a hinge 48. In use, the neck 12 is pivoted toward the body 14 from the position shown in FIG. 5 to the position shown in FIG. Due to wear or normal tolerance of the hinge 48, some deviation may occur as shown in FIG. Such misalignment is addressed by engaging surface 41 with surface 43 while moving neck 12 from the position shown in FIG. 5 to the position shown in FIG. 6 and to the position shown in FIG. .

  The function of screwing the bolt 31 into the hole 49 is not affected by the deviation. This is because appropriate alignment between the bolt 31 and the hole 49 is possible by the elongated hole 29.

  If the guitar is configured as shown in FIG. 7, the bolt 31 may be tightened to the position shown in FIG.

  Referring to FIG. 9, instead of the bolt 31, an insertion fitting portion 131 including a retainer washer 133 and an arm 134 may be used. As shown in FIGS. 10 to 11, the arm 136 of the plug fitting 131 is engaged with the lamp 136. The lamp 136 has a shallow side 140 and a high side 142. In use, after passing through the notch 144, the arm 138 engages the shallow side 140 and is rotated to the high side 142 and is securely locked in place as shown in FIG.

  Referring to FIG. 13, a musical instrument constructed in accordance with the present invention is shown, which uses the self-aligned structure of the present invention. Although the present invention is used in connection with acoustic guitars, electric guitars, violins, violas, basses, banjos or other stringed instruments, an acoustic guitar 10 is shown for purposes of illustration.

  Generally, the guitar 10 includes a large hollow body 12 that is secured to the neck 14 of the present invention. Neck 14 includes a head 16 that houses a spool 18 in a conventional manner.

  The main body 12 includes a front plate 20, which defines a sound hole 22.

  According to the present invention, it is intended that the guitar at the position shown by the solid line in FIG. 38 can be put into the guitar case 810 of the present invention when the guitar case is at the position shown in FIG. Similarly, when in the playing position, the guitar fits in the guitar case 910 of the present invention shown in FIGS.

  When the guitar is completely folded with the neck shown in 1014a, the guitar fits into the guitar case when the guitar case 810 is in the position shown in FIG. Similarly, to place such a folded guitar in the case shown in FIGS. 32-37, the neck zipper is opened and the neck top and bottom protectors and neck sidewalls are folded to a position similar to that shown in FIG. It may be fixed using a face tape.

  In accordance with the present invention, it is contemplated that in all embodiments the zipper may be a zipper that operates in two directions to add functionality.

  FIG. 20 shows the hinge in the folded position as installed according to the present invention, and fitting the butt plates 61 and 63 of the hinge 48 into the pockets 50 and 52 and attaching them to the final assembled structure. A method of positioning screws 56 and 58 is shown. According to the present invention, this structure is intended to be formed by bonding the fretboards 34 and 40 in place after the pockets 50 and 52 are cut and formed in the net 14 and block 50 of the guitar body 12. . The neck 14, neck base 38, neck fretboard 34 and main body fretboard 40 are shown in the stored or moved position of the neck of the instrument. The hinge of the present invention is also suitable for other applications where the surface available for the hinge mechanism is very narrow and needs to be able to support a relatively long vertical surface.

It may be convenient to play the guitar after fixing the bolt 31.

  Referring to FIG. 21, an alternative embodiment of the present invention will be understood. The guitar 510 with the guitar body 512 has a continuous side plate continuation that defines a notch 584 that houses a hinge 548. Therefore, the portion 582 of the side plate 515 is sandwiched between the heel block 538 and the neck 514. For example, the neck 514 is fixed to the performance position by the screw 531 by the method of the embodiment of FIGS.

  If it is desired to secure the neck particularly tightly, the portion 584 of the heel block 538 may extend by cutting the side plate 515 to fit the portion 584. As a result, the heel block is flush with the side plate.

  FIG. 22 shows yet another alternative embodiment of the guitar 610 of the present invention comprising a guitar body 612 and a guitar neck 614 in a folded or moved position. In this embodiment, the neck 614 is folded at a folding point 690, and the folding point 690 is coincident with the folding point to which the hinge bolts 661 and 663 are connected, and is inside the side plate 615 as shown in FIG. As a result, the neck 614 is further supported by the side wall 692.

  Referring to FIG. 23, guitar 710 incorporates a protruding heel block 738, as suggested above.

  According to the present invention, it is intended to fold the guitar neck while inserting the guitar string through the hole into the guitar body. It is also contemplated that the structure of the present invention may be applied to solid body guitars such as electric guitars. In this case, there is no hole (in an acoustic guitar, the hole reaches the body of the acoustic guitar). Therefore, the space for strings is limited. In accordance with the present invention, it is contemplated that a slot or troth, or cylindrical or spherical volume may be cut into a solid guitar to create a place to place the strings. Alternatively, a hole having a diameter of, for example, 5 centimeters may be cut out of the guitar. The string of the guitar is passed through this hole so that it can be placed flat against the back of the guitar.

  While exemplary embodiments of the present invention have been described, it should be understood that various modifications will be apparent to those skilled in the art. Such variations are within the spirit and scope of the invention as illustrated and defined only by the appended claims.
