Abstract
A mechanism for secure engagement of slideable elements in dovetail or similar tracks. The mechanism comprises a pair of plate-like clamping elements adapted to be received within a slide track. The plates are disposed in non-engaging face-to-face relation having a spacer element positioned therebetween adjacent lower edges of the plates. The lower edges project outwardly in relation to the spacer at an angle to engage interior sidewalls of a slide track. A lever element is adapted to converge the upper portions of the plates in a direction towards the spacer and thereby force the lower edges securely against the slide track. The spacer element can be rotatably mounted and can have a non-circular cross section to facilitate installation and removal of the mechanism.
Claims10
A clamping mechanism for securing a slideable member to a slide track, wherein the slide track has a channel with spaced apart side walls, a bottom and an open top, and having a width at the bottom greater than a width at the top to form a restricted entrance opening, which comprises
- (a) a pair of opposed clamping elements adapted to be received through said restricted entrance and having inner end portions thereof engageable with portions of said side walls spaced farther apart than at said entrance,
- (b) a support body for movably supporting said clamping elements with said inner end portions thereof exposed for reception in said slide track channel,
- (c) a fulcrum element positioned between and engaging said opposed clamping elements closely adjacent the inner end portions thereof,
- (d) outer portions of said clamping elements extending outward from said fulcrum element for a predetermined distance, and
- (e) means for applying closing pressure to the outer portions of said clamping elements to forcibly urge the inner portions thereof to pivot outwardly against side wall portions of said slide track channel to lock said mechanism against sliding movement in said channel.
2-5. (canceled)
A mechanism for secure engagement of slideable elements in a slide track having sidewalls with inner portions thereof spaced farther apart than outer portions thereof comprising
- (a) a pair of clamping plate elements disposed in face-to-face relation and having upper and lower portions and a pivot between said upper and lower portions;
- (b) said clamping plate elements having lower edges adapted to project outwardly at a predetermined angle to engage inner portions of said sidewalls of said slide track;
- and
- (c) a means adapted to forcibly converge upper portions of said clamping plate elements towards one another to forcibly urge said lower edges securely outward against the inner portions of said sidewalls.
A clamping mechanism for securing a slideable member to a slide track, wherein the slide track has a channel with a restricted entrance opening and spaced apart side walls, which comprises
- (a) a pair of opposed clamping elements adapted to be received through said restricted entrance and having inner end portions engageable with said sidewalls,
- (b) a support body for movably supporting said clamping elements with said inner end portions thereof exposed for reception in said slide track channel,
- (c) a fulcrum element positioned between and engaging said opposed clamping elements closely adjacent the inner end portions thereof,
- (d) outer portions of said clamping elements extending outward from said fulcrum element for a predetermined distance, and
- (e) means for applying closing pressure to the outer portions of said clamping elements to forcibly urge the inner portions thereof outwardly against sidewall portions of said slide track channel,
- (f) said fulcrum element including first portions engaging said clamping elements and second portions supported in said support body,
- (g) said first portions being of non-circular shape and said second portions being of generally circular shape.
A clamping mechanism for securing a slideable member to a slide track, wherein the slide track has a channel with a restricted entrance opening and spaced apart side walls, which comprises
- (a) a pair of opposed clamping elements adapted to be received through said restricted entrance and having inner end portions engageable with said sidewalls,
- (b) a support body for movably supporting said clamping elements with said inner end portions thereof exposed for reception in said slide track channel,
- (c) a fulcrum element positioned between and engaging said opposed clamping elements closely adjacent the inner end portions thereof,
- (d) outer portions of said clamping elements extending outward from said fulcrum element for a predetermined distance, and
- (e) means for applying closing pressure to the outer portions of said clamping elements to forcibly urge the inner portions thereof outwardly against side wall portions of said slide track channel,
- (f) said fulcrum element comprising a wider portion and a narrower portion, and
- (g) said fulcrum element being rotatably mounted in said support body for selectively positioning said wider or narrower portions between said clamping elements.
