Description

Self-aligning folding guitar {A SELF ALIGNING FOLDING GUITAR}

The present invention relates to a folding guitar having a position fixing mechanism.

The production of sound producing instruments began with the study of the closest mechanically to the human voice. In fact, it was the Middle Age, the Renaissance, and the Near East.

Stringed instruments have been known since ancient times. This included a lute, a resonance part, and other instruments with a fingerboard. The bronze artwork of the New Kingdom (Ancient Egypt, 1380 BC) of art collection bends one knee in one posture, the left hand manipulates the high fingerboard, and the right hand pushes the string and lifts the toe and dances Describes Vian, which can be an example of a modern rock musician.

However, the lute, which was derived from the western Semtion nomadic people who preached the instrument to Mesopotamia, has a much longer history, and the archaeological record dates back to the Acadian era (2350-2170 BC), possibly the Medieval Hyksos dynasty Dynasty, 1730 ~ 1580 BC) was told to the Egyptians at the end of.

In recent years, lute-stringed instruments have become one of the most popular instruments. Folk artists throughout the United States have sometimes used handmade guitars in a wide range of musical genres, including blues and bluegrass.

Unlike percussion, the need for amplification of strings, reeds, and the relatively weak sound source of trembling human lips has been a challenge for early musical instrument manufacturers. This challenge was largely solved by a resonance system that mechanically collects, concentrates, and outputs sound sources. If a sound source of high quality can be generated, a stringent criterion for the stability of the musical instrument is required.

Also, over the years, acoustic string players have introduced a wide variety of state laws to their music using these stringed instruments. If the ancients had just bounced the lute 's strings to get a decaying even sound, the later artists used the bow to produce a relatively constant and somewhat controllably amplified sound. Modern artists use a variety of techniques to play. Acoustic blues players can tap instruments with fingertips, palms or fingers. It is possible to bounce the strings even in the violin composition, which is usually played while the hairs are slipping across the strings. For this reason, a greater mechanical stability of the musical instrument is required.

Because of the popularity of stringed instruments, especially guitars, people often take guitars when traveling. However, string instruments are bulky and not suitable for convenient transport. String instruments are not easy to place in the stowaway space or under the seat. In response to this problem, a guitar having a folding neck has been proposed. In this regard, reference is made, for example, to US Design Registration No. 516,114, and pending U.S. Patent Application Serial No. 11 / 640,095, filed December 15, 2006. The musical instrument is effective, but it is extremely difficult to make handwriting and fine adjustment.

Therefore, we need string instruments such as guitar, violin, etc., which can consistently and accurately change the artistic expression to sounds or other activities, are easy to use, and easily transportable. It is believed that the structures disclosed herein are the most effective means of providing a musical instrument with a high degree of mobility that can be adjusted according to the user's preference.

The present invention also relates to a hinge, commonly known as an "invisible hinge " used in connection with doors and other shaking things, and the invention described herein relates to a hinge having a very narrow surface, In comparison with conventional designs for certain applications in which the hinge must be able to support a much longer vertical surface in proportion to this. Also, an important aspect of the present invention is the method used to locate and install the hinge.

In this type of hinge, the hinge component is connected by an axially rotated interlocking member which hinges by the hinge pin, slides by the sliding pin, and is inserted into the pocket or compartment inside the hinge component, Or inside the hinge piece. The initial model of this hinge is a hinged design by Joseph Soss, named after him. In this regard, it is particularly described in U.S. Patent Nos. 1,030,936, 1,484,093, 1,688,996, 1,984,092 and 2,178,271. This type of hinge is used in the design patent.

These hinges are designed to be invisible when in the closed position and extend below the surface so that the center of the hinge is located below the surface when in the closed position and then fully open at 180 degrees. Two basic models of hinges are common, the first model having a long and narrow body with two attachment screws, the attachment screws being located at each end. The shape of which is of the shape necessary for multi-layer mortise cutting for installation and the second model is of a cylindrical shape with a face, with screws as attachment means and requiring holes drilled for installation, Barrel type hinge.

While these conventional designs have similar characteristics, they do not have the necessary clearance, so they have an unsuitable or unrealistic attachment method for guitars with folding necks and also require complicated procedures for forming the openings for hinges or cylinders.

In addition, although the application of conventional design models has proven to be somewhat supported by US Design Registration No. 516,114, deficiencies have been found in many areas for effective production beyond the capabilities of small scale assemblers.

First, a hinge known as a "barrel-shaped hinge " requires, for example, a final outer surface corresponding to a fretboard of a musical instrument to be attached without going through a normal production procedure, and a hole, which is very close to the surface of the fretboard, Lt; RTI ID = 0.0 > fretboard < / RTI >

Secondly, these hinges are very difficult to set accurately for depth and alignment. Other models of the Soss hinge include better fixation means and better position and depth control means. However, the design allows only one hinge to be fastened to a portion where structural integrity is lacking in this application and the ability to precisely align the two hinges is insufficient. In addition, the position of the setscrew is very close to the outer edge of the member, and in this case, a problem arises due to the lack of material for properly fixing the screws themselves. Finally, the means necessary to cut mortals is very long and is difficult to cut consistently.

According to the present invention, a stringed instrument comprises a neck extension main portion having a neck extending fixed end, a tuning assembly support head end, an extension upper portion, and an elongated portion extending between the ends. The neck extension lumen forms a neck cutaway volume adapted to receive the hinge piece. The neck extension cutaway volume is extended to open at the top of the neck extension fixed end and the neck extension mains. The neck base member includes a neck base fixed end, a base base, and an opposite end thereof. The neck base housings can form a neck base cutaway volume adapted to receive the hinge pieces. The neck base cut away volume is extended to open at the top of the neck base fixed end and the neck base main member. The hinge includes a first hinge piece located within the neck extension cutaway volume and a second hinge piece located within the neck base cutaway volume. The neck fret board portion is fixed on the open top of the neck extension cut away volume and is supported on the first hinge piece. The base cover is fixed on the open top of the neck base cut away volume and is supported on the second hinge piece. The string main body is fixed to the neck base main part.

The two or more Soss link assemblies are connected to a pair of hinge pieces, each hinge piece having a pair of Soss hinge links receiving the races to form a pair of spaced apart Soss hinge assemblies formed on the pair of hinge pieces.

Each of the hinge pieces forms a setscrew receiving bore oriented to extend the length of the stringed neck.

The neck extension main body is provided with a use mounting base, and the neck base main body forms a hole for receiving the screw. This allows the neck base main part and the neck extension main part to be fixed in the use position.

The hinge of the present invention includes a first hinge piece that forms a first pair of races and a second pair of races for receiving a first soss sliding hinge pin. The second hinge piece forms a pair of third and fourth races for receiving the second soss sliding hinge pin. A first Soss link assembly is installed in and between the first and third races. A second Soss link assembly is installed within and between the second and fourth races and the second Soss link assembly is positioned adjacent and spaced apart from the first Soss link assembly, And extends in the same direction.

According to a preferred embodiment, the first hinge piece forms an opening between the first and second races. The second hinge piece forms a hole between the third race and the fourth race. The hole is adapted to receive the attachment member for securing and attaching the hinge to a member to be hingedly mounted.

The hinge piece may be a rectangle having a flat side portion and a rounded corner portion or a flat side portion indicating, for example, a corner portion of 90 degrees.

The holes between the first and second races may be aligned in substantially the same direction as these races.

According to the invention, the alignment provided by the improved hinge can be further improved by the self-aligning locking mechanism according to the invention. Such a device may be a screw or a bayonet type fastener.

According to the present invention, the self-aligning foldable guitar includes a neck portion and a trunk portion. And a hinge is provided on the neck portion and the body portion. A first alignment member is fixed to the neck portion. A second alignment member is fixed to the body portion, and the second alignment member meets the first alignment member at a substantially fixed position. And a fixing member fixes the first alignment member to the second alignment member.

The first alignment member may include a conical surface.

The first and second alignment members may have mutually coinciding surfaces.

The fixing member is a threaded member.

The fixing member may be a bolt or a Bayer net.

Preferably, the first alignment member may form a rectangular bore for receiving the fixing member.

The first alignment member includes a tubular member having internal threads, and a frustroconical stud screwed into the tubular member.

The second alignment member may include a solid body having a receptacle that cooperates with the cone-shaped stud, further forming a threaded bore for receiving the anchoring member.

According to the present invention, there is provided a case capable of accommodating a folding guitar in a folded position or in a deployed use position.

The other case of the present invention includes a guitar body case portion, a guitar body cover, and a neck portion case upper portion. A neck portion case lower portion and a neck portion case side wall are also formed. And the upper neck fastener secures the upper portion of the neck case to the side wall of the neck portion.

Referring to Fig. 1, the neck 12 of the folding guitar 10 is provided with a male alignment 15. The adjusting member (15) includes a docking member (17) screwed into the threaded bore (19). The docking member 17 includes a head 21 and a threaded integral threaded member 23.

In addition, the adjusting member 15 includes a rectangular tube 25 including an upper flange 27. The upper flange 27 forms a rectangular hole 29. As will be described in greater detail below, the rectangular hole 29 receives a bolt 31 (FIG. 3) including a frictionally engaged retainer washer 33.

4, a pair of arm members 35 are provided in the other body 14, which extends beyond the bout 26 to support the support block 50 of the bout 26 It goes. The bolt 37 passes through the support block 50 and is engaged with the arm member 35. [ The arm member 35 includes a receiving cone 39 which receives the head 21 to secure the neck 12 against the other body 14, Lt; / RTI >

As shown in FIG. 5, the neck 12 is mounted on the other body 14 by a hinge 48. In use, the neck 12 is rotated toward the body 14 at the position shown in Fig. 5 and at the position shown in Fig. Due to wear or normal tolerances of the hinge 48, there is some inconsistency, as shown in FIG. This discrepancy is relieved by the coupling between the surface 41 and the surface 43 during the progression of the neck 12 from the position shown in Fig. 5 to the position shown in Fig. 6 and to the position shown in Fig.

The discrepancy does not affect that the bolt 31 can be screwed into the bore 49 because the rectangular hole 29 properly aligns the bolt 31 and the bore 49. [

Once the guitar is arranged as shown in Fig. 7, the bolt 31 can be tightened to take the position shown in Fig.

9, a bayonet 131 including a retainer washer 133 and an arm 134 may be used instead of the bolt 31. As shown in Fig. A ramp 136 is engaged by the arm 138 of the Bayer net 131, as shown in Figs. The lamp 136 is comprised of a shallow side 140 and a high side 142. In use, the arm 138 engages the shallow side 140 after passing through the notch 144, and is rotated to the high side 142 to be securely in place, as shown in Figure 12 .

Referring to Fig. 13, a musical instrument constructed in accordance with the present invention in which the self-adjusting structure of the present invention is used is shown. The acoustic guitar 10 is described for illustrative purposes, although the invention may be used in connection with acoustic or electric guitars, violins, violas, bass, banjo or other stringed instruments.

In general, the guitar 10 includes a large hollow body 12 secured to the neck 14 of the present invention. In a conventional manner, the neck 14 includes a head 16, which includes a tuning screw 18.

The body (12) includes a top plate (20) formed with a bell hole (22). The bottom plate 24 is fixed to the top plate 20 by bows 26 and 28 and all of the bows 26 and 28 are connected to the other sound box sidewalls 20, The center curved bout 30 and the center curved bout 32 (not shown) form the waist of the musical instrument.

The neck 14 supports a neck fretboard 34, and the neck fret board is attached to the neck 14. The neck fret board 34 supports a plurality of frets 36. The neck base 38 supports the neck base fret board 40, and the neck base fret board is attached to the neck base 38. The neck base fretboard 40 supports a plurality of frets 42, and the string 44 is operated by leaning against the frets. For purposes of clarity, the strings 44 supported by the bridge 46 are shown partially in phantom. The other neck 14 can be folded by rotating in the direction of the arrow 47.

A preferred embodiment of the hinge 448 for use with the self-adjusting mechanism of the present invention is shown in Figures 14-16. The hinge 448 includes a Soss link assembly 449 that includes a hinge link 468, a hinge pin 470, a hinge pin 472, and a pin 478. The operation of these hinges is similar to other Soss hinges. However, an advantage is provided by the placement of the threaded holes 476, by virtue of this being that since the threaded holes are located in the vicinity of the side portions 477 of the hinges 448, For example, a screw into a neck, thereby providing excellent support. At the same time, the thickness 481 of the sidewall 479 is relatively small, which can increase the thickness for the Soss link assembly 449. The tilted track 474 serves to provide the necessary configuration so that the hinge can be used in a guitar with a hinge neck.

Further, by the thin receiving recess 481 capable of accommodating a relatively large head of the rigid pin 470, it becomes compact and durable.

According to a particularly preferred embodiment of the present invention, as shown in Figs. 17 and 18, it has been found that a modification of the short hinge is relatively preferable. Otherwise, the hinge 548 is similar to the configuration of the hinge 448. Part of the advantage of this arrangement can be seen from FIG. 19 where the short lever arm is actuated through the screw 583 as the hinge piece is lowered to ensure the integrity of the hole 585 in which the screw 583 is mounted Thereby promoting long-term stability of the guitar body 512 and the other neck 514.

According to a preferred embodiment, the hinge 548 includes a side wall 579 having a thickness of approximately 0.25 cm. The thickness 587 of the hinge link 568 is also 0.25 cm. The side wall 579 has a height 589 and a length 591 of 2 cm. The side wall 579 has a length 593 of 2 cm. Also, according to a preferred embodiment, the hinge 548 has a width 595 of 4 cm.

Referring to FIGS. 24 to 31, the other case 810 of the present invention includes a main body upper cover 812. The main body lower portion 814 can be coupled to the upper cowper 812 by a zipper 816. And the handle 18 is fixed to the lower portion 814.

Further, the neck top cover 820 is fixed by the zipper 816. [ The neck bottom cover 822 is fixed by the zipper 824. In addition, the other case 810 includes a neck side portion 826.

If the case of the present invention is to be opened, the neck top cover 820 is opened by holding the zipper pull 828 to the point 830. Zipper pool 832 continues to point 834. As a result, the other case of the present invention is placed at a position where the upper cover 812 is opened as shown in Fig.

If desired, the zipper pool 832 may be moved from the position shown by the phantom lines in Fig. 26 to a point 834. Likewise, zipper pool 828 can be placed at point 830. This causes the neck top cover 820 to be lifted up, as shown in Fig. The upper cover 820 can then be folded in the direction of the arrow 836 so that the upper cover 820 is disposed on the upper surface of the other case and the Velcro type hook connector 840, Is in contact with and engages with the Velcro type loop connector 842. [

According to a preferred embodiment, zipper pulls 828 and 832 can be moved in both directions. Likewise, the hook connector 844 is configured to contact the loop connector 846 after the zipper 824 is opened, such that the neck side portion 826 is laid flat, . 29, when the hook material 848 and the loop material 850 are engaged with each other, the neck bottom cover 822 is in a state shown in Fig. 29 Location. In addition, hook material 852 may be configured to engage loop material 854.

By providing individual zippers to the neck top cover 820, the other case 810 of the present invention can be configured as shown in Fig.

Subsequently, another modification of the other case of the present invention is shown in Figs. 32 to 37. Fig. In this embodiment, the other case 910 has a central zipper or a combination of a zipper 924 and a zipper 926, which can accommodate many components in the other case of the present invention. For example, the other case is completely sealed and can accommodate a conventional guitar or foldable guitar at the use position, as shown in FIGS. 32 and 33.

In addition, the other case may be opened, as shown in Fig. 36, when the guitar 956 is housed in the case and has a configuration suitable for the guitar opened and folded as shown in Figs. 34 and 35. The zipper pools 958, 960, and 962 can be opened so that the case 110 is in a state shown in Fig. 37, that is, a state in which the guitar can be put into or taken out of the case.

38, the foldable guitar 1010 may have a neck 1014 folded upward as indicated by the arrow 1018, as indicated by phantom lines. This movement can continue until the neck comes to the position of reference numeral 1014a shown in Figure 38 and the wedge neck 1014a and the guitar body 1012 overlap.

According to the present invention, the guitar in the state shown by the solid line in Fig. 38 can be housed in the other case 810 in the state shown in Fig. Likewise, when in the use position, the guitar will also be housed in the other case 910 of the present invention shown in Figs.

When the other neck is completely folded to the position indicated by reference numeral 1014a, the folded guitar is received in the other case 810 in the state shown in Fig. Similarly, this folded guitar is shown in FIGS. 32 to 37, which are secured through hook fasteners and loop fasteners by opening the neck fastener and folding the neck upper and lower protective devices and neck side walls to a position similar to the position shown in FIG. Can be housed in the case.

In accordance with the present invention, for added functionality, the zipper in all embodiments can be a zipper moving in two directions.

Figure 20 shows a mounting hinge in a folded position in which the butt plates 61 and 63 of the hinge 48 are hidden in the pockets 50 and 52 and in the final assembly according to the invention the fixing screws 56 And pockets 50,52 show how the neck 14 and block 50 are located within the guitar body 12 before the fretboards 34,40 are properly positioned. . The neck 14, the neck base 38, the neck fret board 34 and the main body fret board 40 are shown as storage positions or movement positions of the musical instrument neck. The hinges of the present invention may be suitable even if a very narrow surface can be used in the hinge mechanism and thus be able to support much larger vertical surfaces.

Referring to Fig. 13, when the neck 14 is positioned at the open or in the use position with respect to the guitar body 12, the state shown in Fig. 19 is moved from the fully folded position of Fig. 5 to the state shown in Fig. And then the guitar can be conveniently used after the fixing bolt 31 is fastened.

21, a modification of the present invention will be understood. The guitar 510, including the guitar body 512, successively includes a sidewall bout that defines a notch 584 that receives the hinge 548. Thus, a portion 582 of the side wall 515 is interposed between the heel block 538 and the neck 514. The screw 531 fixes the neck 514 to the use position, e.g., as in the embodiment of FIGS. 1-8.

Part of the heel block 538 may extend through the sidewall 515, which is cut out to form the portion 584, particularly if a secure fixation of the neck is desired. As a result, the heel block comes into contact with the side wall.

Subsequently, another variation of the guitar 610 of the present invention including the guitar body 612 and the other neck 614 is shown in Fig. 22 as a folded or moved position. In this embodiment, the neck 614 is folded at a breakpoint 690, which corresponds to a breakpoint where the two hinge bolts 661, 663 are against each other, and as shown in Figure 22, Sidewalls 615, respectively. As a result, the neck 614 is additionally supported by the side wall 692.

Referring to Figure 23, as mentioned above, the protruding heel block 738 of the guitar 710 is embodied.

According to the present invention, as the other neck is tilted, the other string will be inserted through the hole and into the other body. Further, the structure of the present invention may be used as a solid body or the like of an electric guitar or the like. In this case, the acoustic guitar is not provided with a hole for guiding it into the body of the acoustic guitar. Thus, there is a spatial limitation on the prefecture. According to the present invention, grooves or troth, i.e., cylindrical or spherical holes, are made in the solid guitar to provide space for displacement of the strings. Also, in the guitar, for example, a hole having a diameter of 5 cm may be formed. The other strings may pass through the holes and be raised flat against the rear of the guitar.

Although an exemplary embodiment of the present invention has 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, and the invention is only described and defined by the appended claims.
