Cam locking type sliding and swiveling device

A sliding and swiveling device, comprising:

• a sliding plate which includes a surface for supporting an attachment unit and two laterally spaced sliding portions;
• a holder which includes a pair of laterally spaced sliding sections which are in a sliding relationship with respect to the two sliding portions of said sliding plate, said holder further comprising a sleeve portion which is dimensioned for receiving a sleeve member in a swivel relationship;
• first locking means for releasably locking said sliding plate and holder against rotation with respect to the sleeve member;
• second locking means for releasably locking said sliding plate and holder against relative longitudinal sliding;
• a handle member;
• means for triggering a release of said first locking means upon adjustment of said handle member in a first direction and for triggering a release of said second locking means upon adjustment of said handle member in a second direction, and wherein said second locking means includes a push plate rotatably supported by said sliding plate and having a series of engagement protrusions and recesses formed along a free longitudinally extending edge thereof, and said second locking means further comprising one or more protuberances which are designed for reception within said recesses of said push plate and are supported by said sleeve portion,
• and said first locking means including a shaft supported by said sleeve portion and a thrust plate is slideably supported by said shaft such that the thrust plate is shiftable into and out of a slot formed in the sleeve member,
• and said means for triggering including a cam plate rotatably supported by said sliding plate and positioned adjacent said push plate such that upon rotation of said handle member in the first direction said cam plate contacts said thrust plate so as to shift said thrust plate along said shaft so as to unlock said first locking means and upon rotation of said cam plate in said second direction said push plate is rotated out of engagement with said protrusions so as to unlock said second locking means.

A sliding and swiveling device, comprising:

• a sliding plate which includes two laterally spaced sliding portions and two longitudinally extending reception slots positioned between said laterally spaced sliding portions;
• a cam plate rotatably supported in a first of said reception slots;
• a push plate rotatably supported in a second of said reception slots and said cam plate being position so as to come in contact with said push plate upon rotation of said cam plate;
• a holder which includes a pair of laterally spaced sliding sections which are in a sliding relationship with respect to the two sliding portions of said sliding plate, said holder having a first end which includes an engagement member which is engageable with said push plate so as to longitudinally lock said holder and sliding plate;
• a thrust member radially slideably supported by said holder and positioned such that said cam plate, upon rotation, contacts and shifts said thrust member, and said thrust member having a locking portion designed to extend into and out of engagement with respect to a sleeve member which is in a swivel relationship with said holder.

A method of manufacturing a sliding and swiveling device, comprising:

• positioning a sliding plate which includes a surface for supporting an attachment unit, two laterally spaced sliding portions and two longitudinally extending reception slots positioned between said sliding portions;
• positioning a holder which includes a pair of laterally spaced sliding sections that include flange sections, said holder further comprising a sleeve portion which is dimensioned for receiving a sleeve member in a swivel relationship;
• inserting a cam plate within a first of said reception slots so that it is rotatable therein;
• inserting a push plate in a second of said reception slots so that it is rotatable therein and such that it comes in contact with said cam plate upon rotation of said cam plate in a first direction;
• inserting said flange sections of said holder into said two laterally spaced sliding portions;
• securing a thrust plate to said holder so that it is radially adjustable with respect to said holder for locking engagement with the sleeve member supporting said holder in a swivel relationship;
• securing a first biasing device to said push plate to bias said push plate into a longitudinal shift lock engagement with said holder;
• and
• positioning a second biasing device in contact with said thrust plate so as to bias said thrust plate into a swivel lock engagement with the sleeve member.

A sliding and swiveling device, comprising:

• a sliding plate which includes a surface for supporting an attachment unit and two laterally spaced sliding portions;
• a holder which includes a pair of laterally spaced sliding sections which are in a sliding relationship with respect to the two sliding portions of said sliding plate, said holder further comprising a sleeve portion which is dimensioned for receiving a sleeve member in a swivel relationship;
• first locking means for releasably locking said sliding plate and holder against rotation with respect to the sleeve member;
• second locking means for releasably locking said sliding plate and holder against relative longitudinal sliding;
• a handle member;
• means for triggering a release of said first locking means upon adjustment of said handle member in a first direction and for triggering a release of said second locking means upon adjustment of said handle member in a second direction, and wherein said handle member is pivotably supported by said triggering means and pivots about an axis that extends longitudinally in a common direction with longitudinal sliding of said plate upon release of said second locking means.
