Abstract
Abstract A handle of a telescopic handle assembly for a baggage cart includes at least a handle seat fixedly connected to an inner tube of the telescopic handle assembly, an actuator rotatably received within a mounting hole of the handle seat, a grip portion formed by an assembly of two grip members with semi-circular peripheries and being fixedly connected to the actuator so that a rotation of the grip portion can rotate the actuator, and an operating block which has at least a portion being forcedly in contact with a portion of the actuator so that a rotation of the actuator can cause a lifting movement of the operating block from a position to a selected position. The operating block is fixedly connected to a locking means for locking the inner tube with an outer tube of the telescopic handle assembly. Once the operating block is lifted to the selected position, the locking of the locking means for locking the inner tube with the outer tube is unlocked.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
255 words
A handle of a telescopic handle assembly for a baggage cart, the handle assembly having at least one inner tube telescopically received within at least one outer tube and a locking means for locking the inner tube with the outer tube, the locking means being fixedly attached to the inner tube and being able to be shifted between a locking mode and a released mode, the handle comprising; a handle seat fixedly connected to the inner tube and being provided with a mounting hole; an actuator rotatably received within the mounting hole of the handle seat, said actuator being provided with an actuating surface and being rotatable between a first position and a second position; a grip portion fixedly connected to the actuator and being rotatable to rotate the actuator relative to the handle seat; an operating block provided with an actuated surface forcedly in contact with the actuating surface of the actuator and movable to a third position following the rotation of the actuator to the first position, and to a fourth position following the rotation of the actuator to the second position; and a connecting means fixedly connecting the operating block and the locking means; whereby, when the operating block is moved to the third position, the locking means is shifted to the locking mode to lock the inner tube with the outer tube, and, when the operating block is moved to the fourth position, the locking means is shifted to the released mode to unlock the inner tube from the outer tube.
Claim 2
Dependent Claim
255 words
A handle of a telescopic handle assembly for a baggage cart, the handle assembly having at least one inner tube telescopically received within at least one outer tube and a locking means for locking the inner tube with the outer tube, the locking means being fixedly attached to the inner tube and being able to be shifted between a locking mode and a released mode, the handle comprising; a handle seat fixedly connected to the inner tube and being provided with a mounting hole; an actuator rotatably received within the mounting hole of the handle seat, said actuator being provided with an actuating surface and being rotatable between a first position and a second position; a grip portion fixedly connected to the actuator and being rotatable to rotate the actuator relative to the handle seat; an operating block provided with an actuated surface forcedly in contact with the actuating surface of the actuator and movable to a third position following the rotation of the actuator to the first position, and to a fourth position following the rotation of the actuator to the second position; and a connecting means fixedly connecting the operating block and the locking means; whereby, when the operating block is moved to the third position, the locking means is shifted to the locking mode to lock the inner tube with the outer tube, and, when the operating block is moved to the fourth position, the locking means is shifted to the released mode to unlock the inner tube from the outer tube.
Claim 3
Dependent Claim
37 words
A handle according to claim 1, wherein the grip portion is formed by the assembly of two grip members respectively configurated to have a semi-circular periphery, thereby to form the grip portion to have a circular periphery.
Claim 4
Dependent Claim
121 words
A handle according to claim 1, wherein the grip portion is formed by the assembly of a first grip member and a second grip member, each grip member having a semi-circular periphery, the first grip member having at least one hole formed therethrough and the second grip member having at least one threaded hole formed thereon, the actuator being integrated with a rod with at least one hole formed therethrough, the actuator fixedly connected to the two grip members by passing at least one threaded bolt through the hole of the first grip member and then the hole of the rod, and, finally threadedly engaging the threaded portion of the threaded bolt with the threaded hole of the second grip member.
