In the regard, there is ample room between the pivot point and the shaft 560 of the stand 550 to provide clearance for the extension 620 as the leg 600 is rotated relative to the base to a storage position.
(76) Legs 630, 640 and 650 are similar to leg 600.
(77) Turning now to
(78) The upper cradle 370 has a holder 380. The holder 380 has a top piece 381 and a bottom piece 382. A central hole 383 passes through the top piece 381 and bottom piece 382 and is centrally aligned therewith. The top piece 381 is separated from the bottom piece 382 with two side walls 384. One sidewall 384 has a threaded sidewall hole 385 formed there through. The sidewall hole 384 is preferably generally parallel to the central hole 383. Two end holes 386 are also provided. The holder has a general box shape with openings on two sides and faces on four sides.
(79) A lock 390 having a turning element 391 and a threaded element 392 is further provided. The threaded element 392 can be turned into and out of (i.e. translated) within sidewall hole 384 under operation of the turning element 391.
(80) A cradle element 400 is further provided having a collar 401, a first side piece 402 and a second side piece 403. The cradle element 400 is preferably formed of a single rigid piece of material. The collar preferably has an elongated and closed loop shaped structure with parallel side walls having a width less than a width of the holder between sidewalls 384. The first and second side pieces 402 and 403 are divergent from each other, preferably generally at a right angle. Yet, it is appreciated that other angles of divergence could be used without departing from the broad aspects of the present invention.
(81) In use, the collar 400 is inserted into an end hole 386 of the holder 380. Then the holder is placed upon the shaft by receiving the shaft 360 through the central hole 383. The shaft 360 also passes through the collar 401 of the cradle element 400. The threaded element 392 of the lock 390 is then received within hole 385 of the holder.
(82) The top cradle is adjustable with at least three adjustments relative to the shaft 360. First, the cradle element 400 can move perpendicularly (in and out) relative to the shaft. The perpendicular adjustment is bound in both directions when the shaft engages one of the ends of the collar, respectively. In this regard, the shaft engaging the ends of the collar also prevents over travel and removal of the cradle element from the holder 380. Second, the holder 380 is vertically movable relative to the shaft via hole 383. Third, the holder can revolve about the shaft axis within hole 383 allowing for radial or rotatable adjustability. The lock 390 can fix the top cradle 370 in position relative to the shaft 360 by being turned into the holder until an end of the threaded element 392 abuts the collar 401 with sufficient force to make the collar likewise abut the shaft 360. These three adjustments allow for infinite adjustability within the travel limits of the cradle.
(83) Looking now at
(84) Turning now to
(85) The holder 480 is preferably formed of a block 481 that is generally box shaped having six sides. A central hole 483, a side hole 485 and end holes 486 are formed in or through the block 481. The central hole 483 passes through the block and has a central hole diameter. The side hole 485 is threaded, and is open to both an outside of the block and to the central hole 483. The central hole 483 is aligned generally perpendicularly relative to the side hole 485. There are preferably two end holes 486 that extend all the way through the block 481 in directions generally perpendicular to both the central hole 483 and the side hole 485. The end holes 486 are preferably generally slot shaped, wherein they are wider than they are tall. One end hole 486 is open to both the central hole 483 and to the side hole 485. As an alternative, the holes 486 can be oversized relative the objects passing through the holes.
(86) The lock 490 has a turning element 491 and a threaded element 492. The turning element 491 and threaded element 492 are preferably generally perpendicular to each other. The threaded element 492 is received within the side hole 485 and can be selectively turned into and out of the threaded side hole 485 under operation of the turning element 491.
(87) The cradle element 500 is comprised of a fork 501. The fork 501 has a first side piece 502 having a first end and a divergent second end 503. The fork 501 further has a second side piece 504 having a first end and a divergent second end 505. The divergent ends 503 and 505 are generally oriented approximately 45 degrees from their respective first ends, and accordingly form a cradle opening approximately 90 degrees. The first and second side pieces are preferably formed of an integral piece of material and the connection between the sides can accomplished with a semi-circle shaped segment of the material, two right angle turns or other suitable manners of connection.
(88) In use, the member forming the fork 501 is first inserted into end holes 486 of the holder 480. The fork 501 is then formed or bent to its divergent shape. Then the holder is placed upon the shaft by receiving the shaft through the central hole 483. The shaft also passes between the first and second side pieces 502 and 504, respectively, of the cradle element 500. The threaded element 492 of the lock 490 is then received within hole 485 of the holder.
(89) The top cradle is adjustable with at least three adjustments relative to the shaft. First, the cradle element 500 can move perpendicularly relative to the holder 480. The perpendicular adjustment is bound in both directions (in one direction by the segment of material joining the first and second side pieces 402 and 404, and in the other direction by the divergent ends 403 and 405). In this regard, both over travel and removal of the cradle element from the holder 480 is prevented when the shaft is in place. Second, the holder 480 is vertically movable relative to the shaft via hole 483. Third, the holder can have rotatable adjustment as the holder revolves about the shaft axis within hole 383. The lock 490 can fix the top cradle 470 in position relative to the shaft by being turned into the holder until an end of the threaded element 492 abuts a side piece of the cradle element 400 with sufficient force to make the cradle element shift relative to the block 481 within holes 486 until it abuts the shaft. These three adjustments allow for infinite adjustability within the travel limits of the cradle.
(90) Thus it is apparent that there has been provided, in accordance with the invention, a stand for holding an item in a vertical manner that fully satisfies the objects, aims and advantages as set forth above. While the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations as fall within the spirit and broad scope of the appended claims.
