Dimensional adjusting device for computer keyboards racks
First Claim
1. A dimensional adjusting device for enabling adjustment of a computer keyboard rack, said dimensional adjusting device being adapted to be disposed at an underside of a desk surface of a computer desk and to be connected to the computer keyboard rack, comprising:
- a displacement device, said displacement device comprising two slide track units and two opposed track mounts, said slide track units each comprising a fixed track having a track groove, and a movable track being accommodated and slidable in said track groove of said fixed track, said fixed tracks of said two slide track units being disposed between said track mounts, said track mounts having respective upper sides adapted to be connected to the underside of the desk surface, the track mount at a front end of said slide track units having a pair of baffle ends at a front side thereof, and the track mount at a rear end of said slide track units having a pair of baffle ends at a rear end thereof;
a rotary device, having a fixed plate connected to said movable tracks, a rotary support in the shape of an inverted-U disposed beneath said fixed plate, and a spindle passing through and joining said fixed plate and said rotary support such that said rotary support may rotate relative to said fixed plate, said rotary support having two support wings, said support wings each having a center hole and an upper curved slot;
a connecting plate, disposed between said support wings of said rotary support, and having upper pivot holes and upper swing holes at either side of an upper portion thereof for matching said center holes and said upper curved slots of said support wings, said connecting plate further having lower pivot holes and lower swing holes at either side of a lower portion thereof;
an elevating device, said elevating device being passed through said rotary support and said connecting plate for adjustment of upward and downward displacement of said connecting plate; and
an elevation device, said elevation device being passed through two oppositely disposed rack members and said connecting plate that is disposed between said rack members such that said elevation device may allow adjustment of the angle of elevation of said rack members, said rack members having respective upper sides adapted to be connected to the computer keyboard rack, whereina relay plate is disposed between said fixed track and said movable track of each of said slide track units, said relay plate being connected to said movable track and having two plate wings, said plate wings passing through corresponding track holes in said movable track to be further connected to a plate flap at either side of said fixed plate; and
wherein said fixed plate has a positioning device disposed therein, said positioning device comprising a bottom cover disposed over a front portion of said fixed plate, and two trigger pieces, said bottom cover having a partition rib defining a clearance with a front wall of said bottom cover for receiving two oppositely disposed rods with a spring sandwiched therebetween, said rods each having a projection and a stop portion, said bottom cover further having two cover posts positioned behind said partition rib;
said trigger pieces having respective pins, notches and end notches, said pins of said trigger pieces passing through corresponding through slots at a front edge of said fixed plate such that said notches engage said projections of said rods and said end notches engage said cover posts of said bottom cover; and
said positioning device further comprising a top cover for sealing an upper side of said bottom cover so that said rods may advance along said fixed tracks and are positioned in place when said rods pass over said fixed tracks to extend outwardly.

Abstract
A dimensional adjusting device for computer keyboard racks includes a displacement device, a rotary device, a connecting plate, an elevating device, an elevation device, and a positioning device. A relay plate is disposed between a fixed track and movable track of one of two slide track units, the relay plate being connected to the movable track and having two plate wings at both sides thereof. The plate wings pass through corresponding track holes in the movable track to be further connected to a plate flap at either side of a fixed plate. In addition is further characterized in that the fixed plate has a positioning device disposed therein. The positioning device includes of a bottom cover disposed over a front portion of the fixed plate, and two trigger pieces. The bottom cover has a partition rib defining a clearance with a front wall of the bottom cover for receiving two oppositely disposed rods with a spring sandwiched therebetween. The rods each have a projection at an upper side and a stop portion at the other side. The bottom cover further has two cover posts at both sides behind the partition rib. The trigger pieces have respective pins, notches and end notches. The pins of the trigger pieces pass through corresponding slots at a front edge of the fixed plate such that the notches engage the projections of the rods and the end notches engage the cover posts of the bottom cover. The positioning device further includes a top cover for sealing the bottom cover so that the rods may advance along the fixed tracks during displacement, and are positioned in place when the rods pass over the fixed tracks to extend outwardly.
