Full handle for a truck

Claim 1

A handle for a trunk comprising: a main pull link having opposing ends each provided with a square groove; an adjusting bar having opposed ends each of which includes a vertically extending, square hole; a pair of laterally spaced outer tubes each constituting a hollow, square post having a plurality of inner sides with one of said inner sides defining a slideway; a pair of hollow, square extension tubes each having first and second open ends, each of said extension tubes extending through the square hole in a respective end of said adjusting bar with the first open end of each of said extension tubes being received in a respective said square groove and the second open end of each of said extension tubes being slidably received in a respective said outer tube, each of said extension tubes including a section between said first and second open ends that includes a longitudinally extending slot; a pair of ratchet racks each secured within a respective said outer tube; a linking bar extending through said adjusting bar, said linking bar including opposing ends each of which extends through the slot formed in a respective said extension tube; first and second control assemblies each including a fixing seat fitted to the second open end of a respective said extension tube, an engagement tooth member laterally slidably supported by said fixing seat for movement between a fixing position in which said engagement tooth member is interlocked with a respective said ratchet rack and a release position wherein said engagement tooth member may slide along said slideway, and a control plate vertically slidably received within said fixing seat, said control plate being adapted to engage and shift said engagement tooth member to said fixing position when in a first position and permitting said engagement tooth member to assume said release position when in a second position; link means interconnecting said linking bar and the control plate of a respective one of said first and second controller assemblies within each of said extension tubes; and means for biasing each of said control plates towards said first position, wherein manually lifting of said adjusting bar relative to said main pull link causes each of said control plates to shift to said second position through said link means, thereby placing each of said engagement tooth members in said release position and permitting said extension tubes to shift relative to said outer tubes to selectively control the extension of said handle and wherein release of said adjusting bar forces said control plates to assume said first position due to the presence of said biasing means thereby placing said engagement tooth members in said fixing position.
