Patent number: 8697969Abstract: A bridge assembly having a saddle plate, a tremolo block, and a bushing extending through the saddle plate and tremolo block. The bushing has an internal bore, and an engagement member extends through the bushing and is partially disposed in the internal bore. A tremolo arm has an engagement section with a flat engagement surface that defines a plane substantially parallel to a longitudinal axis of the engagement section. The engagement member is perpendicular to and laterally disposed from the internal bore's longitudinal axis. The engagement member frictionally engages the flat engagement surface when the engagement section is disposed in the internal bore. The tremolo arm's engagement section rotates with the busing as a unit relative to the tremolo block.Type: GrantFiled: November 30, 2011Date of Patent: April 15, 2014Assignee: GDK Technologies, Inc.Inventor: Gordon van Ekstrom

Publication number: 20120137851Abstract: A bridge assembly having a saddle plate with a first aperture, and a tremolo block with a second aperture aligned with the first aperture. A bushing extends through the first and second apertures and is rotatable relative to the tremolo block. The bushing has an internal bore with a longitudinal axis and being substantially concentric with the tremolo block's second aperture. An engagement member extends through the bushing and is partially disposed in the internal bore. A tremolo arm has an engagement section with a partially cylindrical shape and a flat engagement surface that defines a plane substantially parallel to a longitudinal axis of the engagement section. The engagement member is perpendicular to and laterally disposed from the internal bore's longitudinal axis. The engagement member is in frictional engagement with the flat engagement surface when the engagement section is disposed in the internal bore.Type: ApplicationFiled: November 30, 2011Publication date: June 7, 2012Applicant: GDK Enterprises, Inc.

Publication number: 20110113946Abstract: A module for removable insertion into a stringed instrument body, the body having a transverse cavity extending from a lateral edge. A first fixation device is attached to the body in the cavity and having electrically conductive contact members. The module includes a base configured to engage the cavity as the module travels along an axis of movement into the cavity. The pickup module assembly having a base slidably inserted into the cavity along an axis from the lateral edge between removed and inserted positions. A plurality of pickups are carried by the base in operative proximity to the strings. A second fixation device is attached to the base and positioned to slideably engage the first fixation device when the base is in the inserted position. First and second electrical connectors are electrically coupled to the plurality of pickups and connected to the second fixation device.Type: ApplicationFiled: November 22, 2010Publication date: May 19, 2011Applicant: GDK Technologies, IncInventor: Gordon Van Ekstrom

Patent number: 7838758Abstract: A module for removable insertion into a body of an instrument having longitudinal strings, the body defining a transverse cavity extending from a lateral edge. The module includes a base configured to engage the cavity as the module travels along an axis of movement into the cavity. A first ball plunger contact is configured to conductively engage a corresponding first contact plate affixed to the body when the module reaches at a first point in movement along the axis and to remain engaged as the module moves into cavity along the axis of movement. A second ball plunger is configured to conductively engage a corresponding second contact plate affixed to the body when the module reaches a second point displaced inwardly from the first point in movement along the axis and to remain engaged as the module continues to move into cavity along the axis of movement.Type: GrantFiled: July 23, 2009Date of Patent: November 23, 2010Assignee: GDK Technologies, Inc.Inventor: Gordon Van Ekstrom
