Bag for emplacing a combinatorial billiard cue

Abstract

A bag for emplacing a combinatorial billiard cue is used to emplace a disassembled combinatorial billiard cue, including a bag unit which contains a billiard cue bottom seat and a billiard cue upper rack. A dent at a bottom of the billiard cue bottom seat to emplace a cue segment includes an extension mechanism contracted vertically when being pressed at a first time and extended vertically when being pressed at a second time. Each cue segment of the combinatorial billiard cue is emplaced from a through-hole of the billiard cue upper rack, putting a bottom of the cue segment in a dent of the billiard cue bottom seat and above the extension mechanism. After the cue segment is pushed down to press the extension mechanism, the extension mechanism is extended vertically, protruding the top of the cue segment out of the billiard cue upper rack to facilitate removal.

1 . A bag for emplacing a combinatorial billiard cue, for emplacing a disassembled combinatorial billiard cue and comprising:
 a bag unit, which is a long body and above which is provided with an upper lid capable of covered and opened;   a billiard cue bottom seat, which is provided at a bottom of the bag unit and is opened vertically with plural dents, an inner bottom of each dent being provided with an extension mechanism that is contracted vertically when being pressed at a first time and extended vertically when being pressed at a second time; and   a billiard cue upper rack, which is provided above the billiard cue bottom seat in the bag unit and is opened with plural through-holes corresponding to the dents;   wherein each cue segment of the disassembled combinatorial billiard cue is emplaced from one through-hole of the billiard cue upper rack, such that a bottom of the cue segment is emplaced in one dent of the billiard cue bottom seat and located above the extension mechanism in the dent, whereas a top end of the cue segment is located close to a top surface of the billiard cue upper rack; after the cue segment is pushed down to press the extension mechanism, the extension mechanism being extended vertically, allowing the top end of the cue segment to protrude out of the billiard cue upper rack.   
     
     
         2 . The bag for emplacing a combinatorial billiard cue, according to  claim 1 , wherein the extension mechanism comprising:
 a bottom seat, which is fixedly connected on a bottom surface of the dent of the billiard cue bottom seat and a central position of which is extended upward with a shaft;   a rotation element, which is pivoted at a top end of the shaft and rotates freely, and an outer surface of which is provided with plural bumps equally spaced apart by a same angle;   a set of extension barrel, which is formed by sheathing orderly plural barrels of diameters that become smaller gradually, with that a bottom of the barrel of the largest diameter is fixed above the bottom seat, each barrel is completely accommodated in the barrel of a larger diameter when being contracted and is protruded on an opening above the barrel of the larger diameter when being extended, whereas a bottom rim is smaller than the opening above the barrel of the larger diameter and keeps inside the opening above the barrel of the larger diameter;   a press element, which is a barrel unit of a diameter smaller than an opening above the barrel of the smallest diameter, an upper end of which is provided with an upper disc of a diameter larger than the opening above the barrel of the smallest diameter, a location close to the bottom rim of which is provided with a collar of a diameter larger than the opening above the barrel of the smallest diameter, and an interior of which, close to the bottom rim, is provided with plural V-shaped blocks equally spaced apart at a same angle, with that the V-shaped blocks correspond to the bumps of the rotation element, the bumps are snapped above the V-shaped blocks when being contracted and the bump slips from a gap between two V-shaped blocks to release the snapping when being extended; and   an elastic element, which is provided between the collar and the bottom seat of the press element and provides an elastic force, allowing the set of extension barrel to be extended upward automatically after the bumps have released the snapping to the V-shaped blocks.   
     
     
         3 . The bag for emplacing a combinatorial billiard cue, according to  claim 2 , wherein the rotation element of the extension mechanism is locked above the shaft of the bottom seat from top by a screw. 
     
     
         4 . The bag for emplacing a combinatorial billiard cue, according to  claim 2 , wherein the elastic element of the extension mechanism is a spring. 
     
     
         5 . The bag for emplacing a combinatorial billiard cue, according to  claim 2 , wherein the elastic element of the extension mechanism is formed by plural spring leaves. 
     
     
         6 . The bag for emplacing a combinatorial billiard cue, according to  claim 2 , wherein an upper side of the upper piece of the press element of the extension mechanism is fixedly connected with a soft pad.
