Description

FIELD OF INVENTION

The present invention relates generally to guitars and guitar accessories. The present invention is more particularly, though not exclusively, related to electric guitar accessories.

BACKGROUND OF THE INVENTION

Since their invention in the 1930s, the electric guitar has been a mainstay in music and has been instrumental in the development of rock and roil and many other genres of music due to its ability to create a variety of sounds and styles. The unique combination of parts coupled with electronic amplification allows the electric guitar to produce their unique sounds and styles. Generally, the electric guitar comprises a body, a neck, headstock, tuning pegs, fret board, frets, pickups, bridge, tailpiece, guitar strings, and strap button screws. The head stock is connected to the neck which is connected to the body, creating the general shape and structure of the guitar. The guitar strings are strung from the headstock, down the neck across the fret board towards the body, passing over the pickups and bridge as they terminate at the tailpiece. At the headstock, the tension of the guitar strings can be adjusted by turning the tuning pegs. The pickups detect the movement of the strings and converts and transmit the string movements into electric signals which is then amplified and turned into sound by an electronic amplifier. Each pluck of a guitar string representing a musical note.

Achieving a vibrato effect, a change in pitch of a musical note, has always been desirable in guitars ever since its invention. Before the invention of vibrato devices for guitars, guitarist achieved the vibrato effect by using their fingers and pressing down on the string against a fret on the fret board and wobbling their fingers back and forth. To produce a wider vibrato effect, instead of wobbling their fingers in one location, guitarist slid their fingers up and down the neck while simultaneously pressing down on the string against the frets on the fret board. Using these methods, guitarists were able to achieve the vibrato effect on only the strings they were able to hold down with their fingers. The introduction of vibrato devices allowed guitarist to create a vibrato effect on all of the strings simultaneously. The vibrato device produces a vibrato effect by changing the tension of all the guitar strings simultaneously using a single control lever, also known as a whammy or a vibrato bar.

An exemplary example of a vibrato device is the Bigsby® B3 vibrato device comprising of only a single string bar serving as a tension and hold bar. The Vibrato device includes a spring loaded control lever (whammy/vibrato bar) fixedly attached to a string hold bar, housed in a solid body for attachment to a guitar. The vibrato device is attached towards the rear, top surface of the guitar by replacing the bridge, the tailpiece, or both. The guitar strings are then attached to the string hold bar of the vibrato device instead of the original tailpiece of the guitar. When the control lever is pushed downwards, the string bar rotates towards the direction of the guitar strings, relieving tension and creating a low pitch. When the control lever is pulled upwards, the string bar rotates away creating additional tension in the guitar strings resulting in a higher pitch. Releasing the control lever to its natural position returns the strings back to its normal tension resulting in the guitars normal pitch.

However, secure attachment of a Bigsby® B3 vibrato device or similar type vibrato devices to a guitar requires permanent physical modifications to the guitar. The attachment of vibrato devices to guitars requires the removal of the tailpiece, possible removal of the bridge and tapping a plurality of holes into the guitar body, ruining the finish and altering the guitars status as an original piece. Additionally, the tone of the instrument and the structural integrity of the guitar may also be compromised.

Therefore, it is desirable and advantageous to provide an apparatus which enables the attachment of a Bigsby® B3 vibrato device or similar type vibrato devices to a guitar without permanent physical modifications while preserving the original guitar string dynamics by allowing perfect spacing and alignment of the guitar strings. It is further advantageous to provide a device that will not impede the original location of the tailpiece mounting holes for instances where additional accessories may be attached utilizing the tailpiece mounting points such as the Vibrato Retrofit String Tension Kit described in U.S. Pat. No. 7,973,226.

SUMMARY OF THE INVENTION

The Vibrato Block of the present invention achieves perfect spacing and alignment of the guitar strings to provide tuning stability and perfect intonation by positioning the vibrato device in the optimal location on the guitar body without any permanent physical modifications to the guitar body. The Vibrato Block is dimensioned and shaped according to the footprint of the attachment plate of the vibrato device and is made with a predetermined thickness. The overall footprint of the Vibrator Block is equal to the footprint of the vibrato device's mounting plate to provide a large surface area for the vibrato device to mount. The similar shape and dimension allows the Vibrato Block to blend in with the mounting plate of the vibrato device, making the Vibrato Block and mounting plate combination aesthetically pleasing. The Vibrato Block thickness spaces the vibrato device a distance away from the guitar body to achieve optimal spacing for the guitar strings and to keep the tailpiece mounting holes free from obstruction to allow other accessories to be used which utilize the tailpiece mounting points.

In the center of the block is an internal slot sized to accommodate a guitar's rear strap button screw. The Vibrato Block is attached to the guitar body by screwing the guitar's rear button strap screw through the Vibrato Block's internal slot. Loosening the guitar's rear button strap screw allows the Vibrato Block to traverse along the internal slot, however when tightened the screw will create frictional forces between the rear strap button screw, the Vibrato Block, and the guitar to keep the assembly in place. A non-marring, high-friction pad used to prevent damage to the guitar and increase the stability of the Vibrato Block is placed between the guitar body and the Vibrato Block. The ability of the Vibrato Bock to traverse along the internal slot and adjust the height of the attached vibrato device allows the vibrato device and Vibrato Block to be used on various types of different guitar bodies. The vibrato device is attached to the guitar by mounting itself to the Vibrato Block by utilizing the mounting plate's mounting holes and the corresponding threaded mounting points on the Vibrato Block, removing the need for permanent physical modification to the guitar to attach the vibrato device.

The Vibrato Block of the present invention provides a guitar with a secure mounting point for a vibrato device without the need for permanent physical modifications. Additionally, the Vibrato Block provides adjustability to allow the vibrato device to be used with various types of guitars and achieve the desired tuning and intonation. Leaving the tailpiece mounting points unobstructed, other devices such as the Vibrato Retrofit String Tension Kit described in U.S. Pat. No. 7,973226 may be used in conjunction with the vibrato device. Additionally, by avoiding the use of the tailpiece mounting points, it is easier and faster to revert the guitar back to its original form.

DETAILED DESCRIPTION OF DRAWINGS

Referring initially to FIG. 1, a perspective view of the Vibrato Block 100 of the present invention is shown and includes the main body 110 having a front mounting plate surface 114, a rear guitar contact surface 116 having a slight curvature 118, an internal slot 102, a plurality of mounting holes 104, a footprint 106, a thickness 108, and a non-marring, high-friction pad 112. In approximately the center of body 110 is internal slot 102, formed by removal of a portion of the body 110 material extending from the front mounting plate contact surface 114 to the rear guitar contact surface 116. The plurality of mounting holes 104 are formed on the front mounting plate surface 114 of body 110 and are spaced in predetermined locations. In the preferred embodiment, there are four mounting holes 104 with each mounting hole threaded to receive a corresponding screw. The non-marring, high-friction pad 112 is located on the rear guitar contact surface 116 of the body 110 and can be a floating pad, an attached pad, or a material directly coated onto the rear guitar contact surface 116. The use of the non-marring, high friction pad 112 is optional and the Vibrato Block 100 may be used without it.

Referring now to FIG. 2, a front view of the Vibrato Block 100 of the present invention is shown. The internal slot 102 is placed approximately in the middle of the body 110 and extends all the way through, from the front mounting plate surface 114 to the rear guitar contract surface 116. The mounting holes 104 are placed in the body 110 on the front mounting plate surface 114. The body 110 has a footprint 106 defined by the front mounting plate surface 114.

Referring now to FIG. 3, a top view of the Vibrato Block 100 of the present invention is shown. The non-marring, high-friction pad 112 is located on the rear guitar contact surface 116 of the body 110. At approximately the center of the body 110 is internal slot 102. The mounting holes 104 are located towards the edge of the body. The thickness 108 of the Vibrato Block 100 is predetermined based on the spacing needed to position the attached vibrato device 200 for perfect alignment and spacing. The curvature 118 may have a radius 119 that corresponds to the curvature of the guitar body in which the Vibrato Block 100 is being attached to. Alternatively, non-uniform curvatures may be incorporated to cooperate with guitars having different body shapes. The curvature 118 ensures the maximum amount of contact area with the guitar body to provide greater stability and strength to the Vibrato Block 100 and attached vibrato device 200. In certain guitar types, a curvature 118 may not be needed and a flat rear guitar contact surface area 116 may be preferred. The non-marring, high-friction pad 112 increases the stability and strength of the Vibrato Block 100 by providing additional friction between the surfaces and deforming to fill any gaps between the Vibrato Block 100 and the guitar. The use of the non-marring, high friction pad 112 is optional and the Vibrato Block 100 may be used without it. Differing thicknesses 108 and curvatures 118 for the Vibrato Block 100 to accommodate different types of vibrato devices and guitars are fully contemplated without departing from the scope and spirit of the invention.

Referring now to FIG. 4, a perspective view of a generic type electric guitar is shown and generally designated 300. The electric guitar 300 comprises, inter alia, a main body 304 having a front surface 324, an edge surface 326 and a back surface 328, a neck 312, a headstock 314, a fret board 318, a plurality of frets 320, tuning pegs 316, guitar strings 322, a pickup assembly 310, a bridge 308, a tailpiece 306, corresponding tailpiece mounting holes 330 (shown in FIG. 5), rear strap button screw 302, and corresponding rear strap button screw mount 303. The head stock 314 is connected to the neck 318 which is connected to the body 304, creating the general shape and structure of the guitar 300. The guitar strings 322, located on the front surface 324 of the guitar body 304, are strung from the headstock 314 down the neck 312 across the fret board 318 and towards the body 304, passing over the pickups 310, bridge 308, and terminating at the tailpiece 306. The tailpiece 306 and headstock 314 hold the guitar strings 322 securely in place. The pickups 310 detect the movement of the strings 322 and converts and transmit the movement into electric signals which are then amplified and turned into sound by an electronic amplifier.

Referring now to FIG. 5, the Vibrato Block 100 is shown attached to guitar 300 and a vibrato device 200 is attached to the Vibrato Block 100 thereby attaching the vibrato device 200 to the guitar 300 without any permanent physical modifications. In the preferred embodiment, the vibrato device 200 is a Bigsby® B3 or any similar type of vibrato device which includes a mounting plate 202, a main plate 204, a string hold bar 206 and a control lever 208. The mounting plate 202 is further formed with a plurality of mounting holes 212 (shown in FIG. 6) and rear strap button screw pass through 214 (shown in FIG. 6). The guitar strings 322 are removed from the tailpiece 306 and attached to the string hold bar 206 of the vibrato device 200. The tailpiece 306 is removed completely, leaving the tailpiece mounting holes 330 exposed and available for use.

The Vibrato Block 100 is attached to guitar 300 and vibrato device 200 is attached to the Vibrato Block 100. The non-marring, high-friction pad 112 of the Vibrato Block 100 is in contact with the guitar's edge surface 326, providing protection to the guitars surface from damage from the Vibrato Block 100. The non-marring, high-friction pad 112 also increases the stability of the Vibrato Block 100 and attached vibrato device 200. The radius of the curvature 119 of surface 118 of the Vibrato Block 100 is substantially similar to the curvature of the guitar's edge surface 326 to provide maximum contact surface area for maximum stability.

The internal slot 102 of the Vibrato Block 100 is sized to form a clearance fit with the threaded portion of the guitar's rear strap button screw 302 which allows the Vibrato Block 100 to be adjusted along the internal slot 102 when the rear strap button screw 302 is threaded loosely into the corresponding rear strap button screw mount 303 (not shown) on the guitar body 304. The tightening of the rear strap button screw 302 will force the head of the rear strap button screw 302 to come into contact with the mounting plate 202, which in turn presses on the front mounting plate surface 114 of Vibrato Block 100, thereby pressing the non-marring, high friction pad 112 against the guitar edge surface 326 with adequate force to securely hold the Vibrato Block 100 in place. The rear strap button screw 302 may be stock or may be an extended version with an extended threaded portion to accommodate the thickness 108 of the Vibrato Block 100. Alternatively, a screw with a similar thread pattern to rear strap button screw 302 may be used instead of the rear strap button screw 302 in instances where a rear strap button screw 302 is not desired or the use of a rear strap button screw 302 is not plausible.

On the front mounting plate surface 114 of body 110 of the Vibrato Block 100 are mounting holes 104. In the preferred embodiment, there are four mounting holes 104 corresponding to the mounting holes 212 (shown in FIG. 6) of mounting plate 202 of vibrato device 200. Alternative numbers of mounting holes and patterns are fully contemplated without departing from the scope and spirit of the invention as different vibrato devices have different mounting patterns and number of mounting holes. The mounting holes 104 are threaded to accept the stock screws of the vibrato device 200. Alternatively, the mounting holes 104 may be threaded to accept a custom set of screws. The mounting plate 202 of the vibrato device 200 is mounted directly to the body 110 of the Vibrato Block 100 using the stock securing hardware, eliminating the need to directly attach the vibrato device to the guitar body 304.

The footprint 106 of the Vibrato Block 100 is similar to the footprint of the mounting plate 202 of the vibrato device 200. The large surface area of the body 110 allows greater friction between the mounting plate 202 and the front mounting plate surface 114 of body 110 creating a more secure mount. The similar footprints create the appearance of a single continuous piece, creating a sleek and aesthetically pleasing look. The thickness 108 of the Vibrato Block 100 spaces the vibrato block 100 away from the guitar body 304 and the tailpiece mounting holes 330, leaving the tailpiece mounting holes 330 unobstructed and readily available for use. Differing thicknesses 108 and footprints 106 of the Vibrato Block 100 are fully contemplated without departing from the spirit of the invention as similar vibrato devices have different shaped mounting plates and dimensions.

By adjusting the dimensions of the Vibrato Block 100, a variety of different vibrato devices may be attached to any guitar having a rear strap button screw without the need for permanent physical modifications. The ability to adjust the Vibrato Block 100 allows a user to adjust the position of the vibrato device 200 to achieve the tuning and intonation desired. The availability of the tailpiece mounting holes 330 allows the use of additional accessories requiring the use of the tailpiece mounting holes 330,

Referring now to FIG. 6, a rear view of guitar 300 is shown with the Vibrato Block 100 and vibrato device 200 attached. The Vibrato Block 100 is attached to the guitar 300, without permanent physical modification, by using the stock rear strap button screw 302 present on the guitar 300. The footprint 106 of the Vibrato Block 100 is substantially similar to the footprint of the mounting plate 200 and therefore is concealed by the mounting plate 200 making the use of the Vibrato Block 100 aesthetically pleasing. The internal slot 102 allows the Vibrato Block 100 to traverse along the internal slot 102, parallel to the guitar's edge surface 326 in the direction 210. The rear strap button screw pass through 214 allows the rear strap button screw 302 to pass through the mounting plate 202 and contact the front mounting plate surface 114. Alternatively, the vibrato device 200 may not have a rear strap button screw pass through 214 and therefore a screw instead of a rear button strap screw 302 will be used in conjunction with the vibrato device 200. The internal slot 102 will then be formed with a counterbore to allow the screw to sit below the front mounting plate surface 114 to allow the vibrato device 200 to sit flush with the front mounting plate surface 114 of the Vibrato Block 100.

The vibrato device 200 is attached to the Vibrato Block 100 using the vibrato device's 200 stock mounting screws. The screws are placed through the mounting holes 212 of the mounting plate 202 and threaded into the corresponding mounting holes 104 (not shown) of the vibrato block 100. By screwing the screws into the Vibrato Block 100 instead of the guitar 300, no permanent physical modifications are made. By avoiding the physical alteration the original status, the aesthetics, the original tone, and the structural integrity of the guitar are maintained.

Referring now to FIG. 7, a plan view of the guitar 300 is shown with the Vibrato Block 100 and the vibrato device 200 attached. The footprint 106 of the Vibrato Block 100 is substantially similar to the footprint of the mounting plate 200 and therefore is concealed by the mounting plate 202 and the main plate 204. The thickness 108 of the Vibrato Block 100 spaces the vibrato device 200 a distance 312 away from the tailpiece mounting holes 330. The distance 312 allows the tailpiece mounting holes 330 to be unobstructed by the vibrato device 200 and readily available for use. Accordingly, the thickness 108 of the Vibrato Block 100 and the distance 312 may vary depending on the type of guitar 300 and vibrato device 200 used. A person of ordinary skills in the art will appreciate that the thickness 108 and corresponding distance 312 can be modified to accommodate different types of guitars 300 and vibrato devices 200 in order to achieve the optimal placement of the vibrato device 200 for the desired tuning and guitar string intonation.

Referring now to FIG. 8, a perspective view of the guitar 300 is shown with the Vibrato Block 100, the vibrato device 200, and a Vibrato Retrofit String Tension Kit 380. The Vibrato Retrofit String Tension Kit 380 is fully described in U.S. Pat. No. 7,973,226 and is fully incorporated herein. The thickness 108 of the Vibrato Block 100 spaces the vibrato device 200 a distance 312 away from the tailpiece mounting holes 330. The distance 312 allows the tailpiece mounting holes 330 to be unobstructed and available to mount the Vibrato Retrofit String Tension Kit 400. The Vibrato Retrofit String Tension Kit 400 utilizes the tailpiece mounting holes 330 as its own mounting holes thereby avoiding permanent physical modifications to the guitar 300. By attaching the Vibrato Retrofit String Tension Kit 400, an extra degree of adjustment is available for the user to tune their guitar.

Referring to FIG. 9, a perspective view of an alternative embodiment of the Vibrato Block of the present invention is shown and generally designated 400. Vibrato Block 400 includes a main body 410 having a front mounting plate surface 414, a rear guitar contact surface 416 having a slight curvature 418, a mounting hole 402 formed with a counter-sink extending between the front mounting plate surface 414 and rear guitar contact surface 416. Block 400 is formed with a plurality of mounting holes 404, has a footprint 406, a thickness 408, and a non-marring, high-friction pad 412. In approximately the center of body 410 is mounting bore 402. The plurality of mounting holes 404 are formed on the front mounting plate surface 414 of body 410 and are spaced in predetermined locations. In the preferred embodiment, there are four mounting holes 404 with each mounting hole threaded to receive a corresponding screw. The non-marring, high-friction pad 412 is located on the rear guitar contact surface 416 of the body 410 and can be a floating pad, an attached pad, or a material directly coated onto the rear guitar contact surface 416. The use of the non-marring, high friction pad 412 is optional and the Vibrato Block 400 may be used without it.

Referring now to FIG. 10, a front view of the Vibrato Block 400 of the present invention is shown. The bore 402 is placed approximately in the middle of the body 410 and extends all the way through, from the front mounting plate surface 414 to the rear guitar contract surface 416. The position of the mounting bore 402 may vary in direction 420 as determined in order to align with the placement of the Vibrato Device on the side of the guitar body 326. The mounting holes 404 are placed in the body 410 on the front mounting plate surface 414. The body 410 has a footprint 106 defined by the front mounting plate surface 414.

Referring now to FIG. 11, a top view of the Vibrato Block 400 of the present invention is shown. The non-marring, high-friction pad 412 is located on the rear guitar contact surface 416 of the body 410. At approximately the center of the body 410 is mounting bore 402. The mounting holes 404 are located towards the edge of the body. The thickness 408 of the vibrato device 200 (shown this Figure) is predetermined based on the spacing needed to position the attached vibrato device 200 for perfect alignment and spacing.

The curvature 418 corresponds to the curvature of the guitar body in which the Vibrato Block 400 is being attached to. The curvature 418 ensures the maximum amount of contact area with the guitar body to provide greater stability and strength to the Vibrato Block 400 and attached vibrato device 200. In certain guitar types, a curvature 418 may not be needed and a flat rear guitar contact surface area may be preferred. The non-marring, high-friction pad 412 increases the stability and strength of the Vibrato Block 400 by providing additional friction between the surfaces and deforming to fill any gaps between the Vibrato Block 400 and the guitar. The use of the non-marring, high friction pad 412 is optional and the Vibrato Block 100 may be used without it. Differing thicknesses 408 and curvatures 418 for the Vibrato Block 400 to accommodate different types of vibrato devices and guitars are fully contemplated without departing from the scope and spirit of the invention.

While there have been shown what are presently considered to be preferred embodiments of the present invention, it will be apparent to those skilled in the art that various changes and modifications can be made herein without departing from the scope and spirit of the invention.
