Abstract
A wheeled luggage with a third wheel control mechanism in which release button is disposed within the bezel for controlling the extension of third wheel by actuating a connecting rod attached between release button and third wheel control lever in particularly, the extension of the third wheel is actuated simply by pressing the release button provided within the bezel and the retraction of the same is only to push to third wheel bracket plate into the back plate of luggage and to have it locked thereto. The location of the connecting rod is preferable near the retractable handle. By utilizing this, connecting rod is enhanced in mechanical strength for preventing from being deformed by the weight of luggage during transportation, and an easy assembling and a simplified controlling mechanism are obtained.
Claims17
A wheeled luggage with a third wheel control mechanism comprising:
- a luggage;
- a bezel provided on a top of the luggage;
- a retractable handle provided within a rear portion of the luggage;
- a third wheel control mechanism provided below the bezel comprising:
- a release button with the bezel;
- a vertically disposed connecting rod actuated by said release button;
- a pivotal lever actuated by said connecting rod;
- a spring means for keeping said pivotal lever in a horizontal position normally;
- a third wheel bracket plate having a third wheel at a lower portion and a resilient hinge means at an upper portion to have said third wheel bracket plate pivotally attached to a back plate of said luggage;
- and
- a hooking means for locking said third wheel bracket plate onto said back plate of said luggage by engaging with said pivotal lever when retracted;
- whereas when said release button is pressed by user to actuate said connecting rod to force said pivotal lever means to be pivoted about its pivot point, said hooking member releases said pivotal lever means so as to enable said third wheel bracket plate to be extended outwardly by the action of said resilient hinge means thus resulting the third wheel automatically extended to an operating position ready for use.
A wheeled luggage including a main body having a recess in one end thereof, a bezel, and a retractable handle, comprising:
- a third wheel control mechanism provided below the bezel including
- a release button disposed within a portion of the bezel;
- a vertically disposed connecting rod having a top actuated by said release button;
- a pivotal lever actuated by said connecting rod;
- an anchored spring means provided below and urged against the bottom of said pivotal lever in a horizontal position normally;
- and
- a third wheel bracket plate received in the recess of said main body in a first position having a third wheel in a lower end, a first hinge means at an upper end to have the third wheel bracket plate pivotally attached to a back plate of the main body, and a hook means provided at an inner surface of the third wheel bracket plate being locked in the mating pivotal lever;
- wherein the connecting rod is actuated by pressing the release button which in turn compresses the anchored spring means downward to force said pivotal lever to be pivoted about its pivot point, and then in turn makes said hook means disengaging from the mating pivotal lever so as to enable the third wheel bracket plate to be extended outwardly to a second position by the action of said first hinge means, and the third wheel bracket plate is collapsed into the main body by pushing the third wheel bracket plate toward the main body unit said hook means snaps over and catches the mating pivotal lever.
