a) Field of the Invention
The present invention relates to a box for emplacing a combinatorial billiard cue, and more particularly to a bag which facilitates emplacing and removing cue segments of a combinatorial billiard cue.
b) Description of the Prior Art
The billiard ball game is a noble and interesting sport; therefore, it is quite popular. To play the billiard ball game, a user will need a billiard cue in a shape of a long rod to hit balls, in addition to having a pool table. On the other hand, to facilitate carrying the billiard cue in the shape of the long rod, the billiard cue is sometimes designed as a combinatorial billiard cue.
The combinatorial billiard cue can be disassembled into many cue segments and there is already a box (or bag) designed specifically for this kind of billiard cue. For example, the US Patent Publication No. 2007/0125670 A1, “Box (Bag) Structure for Emplacing Billiard Cues,” has disclosed such box.
In this prior art, a top part of the box is provided with a movable protecting block and when the billiard cue is to be taken out, the protecting block should be moved away first to expose a top end of the billiard cue, thereby facilitating the user to take out the billiard cue.
However, this design requires moving the protecting block and thus is very inconvenient in operation. Besides, sometimes the user may forget to assemble the protecting block, causing the protecting block to be lost. Thus, these shortcomings require to be improved.
Accordingly, the present invention provides a bag for emplacing a combinatorial billiard cue to emplace the disassembled combinatorial billiard cue.
The bag of the present invention includes a bag unit, which is a long body and above which is provided with a top lid that can be covered or opened; a billiard cue bottom seat, which is provided at a bottom of the bag unit and is vertically opened with plural dents, an inner bottom of each dent being provided with an extension mechanism that will be 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 provided with plural through-holes corresponding to the dents.
Each cue segment of the combinatorial billiard cue that is disassembled is emplaced from a through-hole of the billiard cue upper rack, allowing a bottom of the cue segment to be emplaced in a dent of the billiard cue bottom seat and located above the extension mechanism in the dent. On the other hand, a top 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 will be extended vertically, allowing the top end of the cue segment to protrude out of the billiard cue upper rack.
The primary object of the present invention is to provide the bag for emplacing a combinatorial billiard cue, wherein due to an effect that the extension mechanism is contracted vertically when being pressed at a first time while being extended vertically when being pressed at a second time is able to be achieved, apparently, as the dent of the billiard cue bottom seat is provided with the extension mechanism, when the user is to take out each cue segment of the combinatorial billiard cue, he or she only needs to press the cue segment again that the top end of the cue segment can exceed the top surface of the billiard cue upper rack, thereby facilitating the user to take out the cue segment.
Furthermore, the extension mechanism of the bag for emplacing a combinatorial billiard cue, according to the present invention, includes 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 upward extended with a shaft; a rotation element, which is pivoted at a top end of the shaft and is able to rotate 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, a bottom of the barrel of the largest diameter being fixed above the bottom seat, each barrel being completely accommodated in the barrel of a larger diameter when being contracted and being protruded on an opening above the barrel of the larger diameter when being extended, whereas a bottom rim of the barrel being smaller than the opening above the barrel of the larger diameter to keep inside the opening above the barrel of the larger diameter; a press element, which is a barrel unit of a diameter smaller than the 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 a bottom rim of which is provided with a collar of a diameter larger than the opening above the barrel of the smallest diameter and in an interior of which, close to the bottom rim, is provided with plural V-shaped blocks equally spaced apart by a same angle, the V-shaped blocks corresponding to the bumps of the rotation element and the bumps being snapped above the V-shaped blocks when being contracted while the bump slipping between two V-shaped blocks to remove 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 automatically in a vertical direction after the bumps have released the snapping to the V-shaped blocks.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
Referring to
The bag unit 11 is a long body and above which is provided with an upper lid 111 that can be covered or opened. The billiard cue bottom seat 12 is located at a bottom of the bag unit 11 and is opened vertically with plural dents 121; whereas, an inner bottom of each dent 121 is provided with an extension mechanism 122. As shown in
The billiard cue upper rack 13 is provided above the billiard cue bottom seat 12 in the bag unit 11 and is opened with plural through-holes 131 corresponding to the dents 121.
Referring to
Moreover, referring to
The bottom seat 31 of the extension mechanism 122 is fixedly connected on a bottom surface of the dent 121 of the billiard cue bottom seat 12 and a central position is extended upward with a shaft 311.
The rotation element 32 is pivoted at a top of the shaft 311 and can rotate freely. Furthermore, an outer surface of the rotation element 32 is provided with plural bumps 321 equally spaced apart by a same angle. The screw 36 is locked above the shaft 311 of the bottom seat 31 from top of the rotation element 32.
The set of extension barrel 33 is formed by sheathing orderly plural barrels 331, 332, 333 of diameters that become smaller gradually, wherein, a bottom of the barrel 331 of the largest diameter is fixed above the bottom seat 31. When being contracted, as shown in
The press element 34 is a barrel unit 341 of a diameter smaller than the opening above the barrel 333 of the smallest diameter and an upper end of the press element 34 is provided with an upper disc 342 of a diameter larger than the opening above the barrel 333 of the smallest diameter. A collar 343, a diameter of which is larger than the opening above the barrel 333 of the smallest diameter, is provided close to the bottom rim; whereas, an upper side of the upper disc 342 is fixedly connected with the soft pad 37. On the other hand, as shown in
On the other hand, the elastic element 35 can be a spring as shown in the drawings or can be formed by plural spring leaves. The elastic element 35 is provided between the collar 343 and the bottom seat 31 of the press element 34. After the bumps 321 have released the snapping to the V-shaped blocks 344, the elastic element 35 will provide an elastic force, allowing the set of extension barrel 33 to be extended upward automatically in a vertical direction, thereby extending the height.
By this extension mechanism, an effect that the extension mechanism will be contracted vertically when being pressed at a first time and extended vertically when being pressed at a second time is achieved.
Apparently, for the bag for emplacing a combinatorial billiard cue of the present invention, as the interior of the dent 121 at the billiard cue bottom seat 12 is provided with the extension mechanism 122, such that when each cue segment 2 of the combinatorial billiard cue is to be taken out, a user only needs to push the cue segment 2 again that the top of the cue segment 2 can exceed the top surface of the billiard cue upper rack, thereby facilitating the user to take out the cue segment 2.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
