Patent ID: 7338023

Claim:
A keyboard carrier, comprising a base for fixedly connecting to an underside of a desk, a slide seat slidably mounted between two sliding rails formed below two lateral edges of said base, a bracket mount connected to an underside of said slide seat, a pair of links and an elevating member pivotally connected at respective rear ends to two front ends of said bracket mount to form an elevation adjusting mechanism for adjusting a height of front ends of said links and said elevating member relative to the desk, and an inclining member pivotally connected at two rear ends to two front ends of said elevating member via a locating mechanism to slide in two curved slots formed at the front ends of said elevating member for adjusting an inclination of said inclining member relative to the desk; and said locating mechanism including: an outer sleeve disposed between said two curved slots formed at two front ends of said elevating member; a braking block having a length slightly smaller than that of said outer sleeve and therefore being axially movable in said outer sleeve, and said braking block being provided at a predetermined position with a round hole, one side of an inner wall of said round hole being provided with a threaded section; a screw rod being pivotally connected at an end to an underside of said elevating member to perpendicularly extend an opposite end through said outer sleeve and said round hole of said braking block; a handle being located at one outer side of said elevating member to be manually operated and pivotally turned; a pivoting mechanism being located between said handle and said braking block, and operable by pivotally turning said handle to axially move said braking block in said outer sleeve; and an elastically movable end shaft being located at one outer side of said elevating member opposite to said handle, and screwed to an end of said braking block; whereby when said handle is pivotally turned from a first position to a second position, said braking block is axially moved in said outer sleeve to tightly press an end against said pivoting mechanism, and said elevation adjusting mechanism and said inclination adjusting mechanism are immovably clamped between said braking block and said washer without the risk of turning, and said screw rod extended through said round hole on said braking block is engaged with said threaded section of said round hole to provide an enhanced supporting force to said keyboard carrier.
