Luggage

Abstract

A luggage includes a suitcase body, a plurality of wheels rotatably disposed under the suitcase body, and a pivotable telescopic pull handle unit disposed on the suitcase body. The pivotable telescopic pull handle unit includes a pair of fixation seats, a pair of pivoting seats, a pair of pivotable engaging units, a pair of telescopic rod units, a pair of telescopic engaging units, and an operating unit. Since rotation of said pivoting seats is driven by the pivotable engaging units, and since rotation of the telescopic rod units is driven by the telescopic engaging units, the luggage can be conveniently operated.

What is claimed is: 
     
         1 . A luggage comprising:
 a suitcase body that has a bottom portion and a top portion opposite to said bottom portion;   a plurality of wheels that are respectively and rotatably disposed under said bottom portion of said suitcase body; and   a pivotable telescopic pull handle unit that is disposed on said top portion of said suitcase body and that includes:
 a pair of fixation seats that are respectively secured on said top portion of said suitcase body; 
 a pair of pivoting seats that are respectively and pivotably disposed in said fixation seats; 
 a pair of pivotable engaging units that are respectively disposed in said pivoting seats, each of said pivotable engaging units including a bottom driving member that is disposed pivotably in the corresponding one of said pivoting seats, a bottom engaging member that is disposed in the corresponding one of said pivoting seats and that is drivable by said bottom driving member so as to move between an engaged position and a disengaged position relative to the corresponding one of said fixation seats, and a bottom biasing member that is disposed between said bottom engaging member and the corresponding one of said pivoting seats for biasing said bottom engaging member toward the engaged position; 
 a pair of telescopic rod units that are respectively disposed on said pivoting seats, each of said telescopic rod units having an outer rod that is secured on the corresponding one of said pivoting seats, and an inner rod that extends through said outer rod and that is movable telescopically along said outer rod; 
 a pair of telescopic engaging units, each of which is disposed in said inner rod of a corresponding one of said telescopic rod units and has a carrier seat that is secured at a bottom portion of said inner rod, a top driving member that is pivotably disposed in said carrier seat, a top engaging member that is disposed in said carrier seat and that is movable by said top driving member between an engaged position and a disengaged position relative to said outer rod of the corresponding one of the telescopic rod units, and a top biasing member that is disposed between said top engaging member and said carrier seat for biasing said top engaging member toward the engaged position; and 
 an operating unit that includes an operating block and a pair of push rods, each of which extends through said inner rod of a corresponding one of said telescopic rod units so as to push said top driving member of a corresponding one of said telescopic engaging units and to be connected to said operating block, 
   wherein, when said pivotable telescopic pull handle unit is disposed in a pull-out state for use, said top engaging members are disposed in the engaged position and said bottom engaging members are disposed in the engaged position; when said operating block is pushed to drive rotation of said top engaging members through said push rods, said top engaging members are driven to move to the disengaged position by said top driving members; and when said operating unit is pushed so that said telescopic engaging units are respectively driven to move toward said bottom portion of said suitcase body by said inner rods, said top driving members urge said bottom driving members to rotate to drive said bottom engaging members to move to the disengaged position, thereby allowing said pivoting seats to rotate and thus position said pivotable telescopic pull handle unit in a storage state.   
     
     
         2 . The luggage of  claim 1 , wherein said bottom driving member of each of said pivotable engaging units includes a pivoting block that is disposed on the corresponding one of said pivoting seats through a pivot shaft, and a pair of driven blocks and a driving block that extend radially from said pivoting block in opposite directions, said bottom engaging member of each of the pivotable engaging units including a pair of engaging blocks that extend through the corresponding one of said pivoting seats and that are movable between the engaged position and the disengaged position relative to the corresponding one of said fixation seats, and a connecting block that connects said engaging blocks and that is drivable by said driving block. 
     
     
         3 . The luggage of  claim 2 , wherein each of said fixation seats further includes a stopper that is formed on a top surface thereof, said engaging blocks of said bottom engaging members being respectively blocked by said stoppers when said pivotable telescopic pull hand unit is in the pull-out state for use. 
     
     
         4 . The luggage of  claim 3 , wherein said stopper of each of said fixation seats is disposed at a junction between a front high portion and a rear low portion of said top surface. 
     
     
         5 . The luggage of  claim 3 , wherein each of said fixation seats is formed with a pair of engaging holes, said engaging blocks of the corresponding one of said bottom engaging members respectively extending through said engaging holes when said pivotable telescopic pull handle unit is positioned in the storage state. 
     
     
         6 . The luggage of  claim 5 , wherein each of said pivoting seats includes a first housing and a second housing that are correspondingly coupled with each other, said first housing having a guide rail, and each of said bottom engaging members further including a guide block that is disposed on said connecting block of the corresponding one of said pivotable engaging units and that is matched with said guide rail of the corresponding one of said pivoting seats. 
     
     
         7 . The luggage of  claim 1 , wherein said carrier seat of each of said telescopic engaging units includes a carrier frame that is disposed in said inner rod of the corresponding one of said telescopic rod units and a pivoting groove disposed in said carrier frame, said top driving member of each of said telescopic engaging units including a pivot shaft that is pivotally disposed in said pivoting groove, a compression plate that is formed radially from said pivot shaft and that is disposed in said carrier frame, a pair of outer driving arms that are bent and extend from said compression plate so as to drive the corresponding one of said bottom driving members, and an inner driving arm that is disposed beneath said compression plate and extends therefrom so as to drive the corresponding one of said top driving engaging members. 
     
     
         8 . The luggage of  claim 7 , wherein each of said top engaging members includes a member body that is movable between said outer driving arms of said top driving member of the corresponding one of said telescopic engaging units, a receiving slot for receiving said inner driving arm of said top driving member of the corresponding one of said telescopic engaging units, and an engaging block that extends from said member body and that is inserted between said inner rod and said outer rod of the corresponding one of said telescopic rod units. 
     
     
         9 . The luggage of  claim 1 , wherein said luggage has an overall height that ranges from 34 inches to 40 inches when said pivotable telescopic pull handle unit is positioned in the pull-out state. 
     
     
         10 . The luggage of  claim 1 , further comprising a lift handle that is mounted between said fixation seats.
