Horizontally retractable handle of wheeled luggage

Abstract

A horizontally retractable handle of wheeled luggage is introduced. The handle is retracted to the top of the luggage when it is not in use. When the handle is in use, the user simply pulls out the handle horizontally, transits the handle from its horizontal position to a vertical position, locks the handle in the vertical position, and then pulls the handle out to its maximum length. When the handle is not in use, the user pushes the handle down and rotates the handle in a reverse direction to transit it from the vertical position to a horizontal position; thereby, pushing the handle horizontally into its preserving recess on the top of the luggage body.

What is claimed is:  
     
         1 . A retractable handle device of wheeled luggage provided on a top of the luggage slidable and extendable from a rear top to a front top of the luggage, the retractable handle device comprising: 
 a handle grip;    a pair of sliding tubes slidable on the top of the luggage, a front end of the sliding tubes connected to the handle grip; and    a pair of locking devices provided at a front portion of the luggage;    wherein by horizontally extending the luggage handle to a front-most extent, performing a rotation of a rear end of each of the pair of sliding tubes causing the locking device to move downward, the luggage handle changes its orientation from a horizontal position to a vertical position, upon changing an orientation of the luggage handle at a predetermined position, the pair of locking devices lock the pair of sliding tubes in place to thereby secure the luggage handle into a position readied for the user's towing operation.    
     
     
         2 . The retractable handle device of    claim 1   , wherein the locking device comprises a solid locking block, a first spring biased against the solid locking block, a hollow locking block, a second spring biased against the hollow locking block, and a casement.  
     
     
         3 . The retractable handle device of    claim 1   , wherein a pair of sleeving members are further sleeved on the sliding tubes of the luggage handle.  
     
     
         4 . The retractable handle device of    claim 3   , wherein the sleeving member comprises a pivotal block and a center block.  
     
     
         5 . The retractable handle device of    claim 1   , wherein each of the said pair of sliding tubes comprises an inner sliding tube and an outer sliding tube.  
     
     
         6 . The retractable handle device of    claim 1   , further comprising a pair of horizontal grooves on the top of the luggage.  
     
     
         7 . The retractable handle device of    claim 6   , wherein a guiding means is further provided in the horizontal grooves.  
     
     
         8 . The retractable handle device of    claim 7   , wherein the guiding means comprises an arcuate guide groove, a first dent, and a second dent.  
     
     
         9 . A retractable handle device of wheeled luggage slidable along two horizontal grooves on the top of the luggage, the retractable handle device comprising: 
 a luggage handle including a handle grip, two outer sliding tubes, and two inner sliding tubes;    a pair of locking devices each provided in the front portion of the luggage handle;    a pair of spring biased members each provided in the rear end of the outer sliding tube; and    a pair of L-shaped guide grooves each provided along the inner wall of a horizontal groove;    wherein by extending the luggage handle, the spring biased members are protruded to be locked in the locking devices when the luggage handle is fully pulled out horizontally; to change the handle's orientation from its horizontal position to a vertical position, the spring biased members are locked in their vertical positions by the activation of the locking devices, thereby holding the luggage handle in place in an operating position.
