Abstract: An assembled wheel structure is constructed of a base, a main body, and-an outwardly protrudent plate. The base is fixed on bottom edges of a traveling bag. The base comprises a first main plate and a reception bracket, wherein the reception bracket has a first reception trench. A first insertion plate and a first fastening device are mounted on both ends of the first main plate, respectively. The main body comprises a second main plate and a wheel bracket, wherein a second insertion plate and a second fastening device are mounted on both ends of the second main plate, respectively. The second insertion plate is inserted into the second reception trench formed between the outwardly protrudent plate and the first main plate. The first and second main plates can be fastened together or detached from one another without the use of any tool.

Abstract: A thermos bag for a baseball bat comprises a bag body and a heater. The inside of the bag body is divided into an inner pocket and an outer pocket by a lining. By unzipping a zipped opening formed on the upper portion of the bag body, the baseball bat can be held inside the outer pocket. A lateral pocket having a cover is mounted on the outside of the bag body. An electric power device and a control apparatus of the heater are held inside the lateral pocket. A power switch is electrically connected to the control apparatus to turn on or turn off a heating device such that the temperature inside the bag body can be maintained to ensure that the crystal structure of the aluminum baseball bat is stable and that the original tenacity and the malleability is maintained to prevent the baseball bat from crack.

Abstract: A bag dedicated for carrying baseball, soft baseball or lacrosse equipment essentially comprised of a bag and two detachable partitioning boards. An inner bag and a bottom pocket provided inside the bag. The inner bag has three zippers connected flap covers and two U-shape guide tracks to respectively receive the insertion of the partitioning board for segregating three compartments. Felt tapes are provided at both internal sides of the inner bag at where corresponding to positioning felt tapes provided at, the bottom of each partitioning board to reinforce the supporting strength of the partitioning board. The bottom pocket has a zipped opening at its front end. The bag allows respective accommodation of baseball, soft baseball or lacrosse equipment depending on the size and quantity of the object to achieve effective arrangement of accommodation space with improved lateral supporting strength from the partitioning boards and permits one-time carriage or transportation.

Abstract: A sucking structure attachable to any bottle or container generally available in the market that is incorporated to a bottle by an external straw provided with a sucker to sip water or other potable liquid contained in the bottle; both of said straw and a water inlet hose inside the bottle are connected to a bottle cap and a connector penetrating said bottle cap with its portion exposed above the cap indicating a barb for the straw to press firmly against the connector when the straw is inserted into the connector while the portion of the connector inside the bottle reduces downwardly as its outer diameter becomes larger upwardly to hold it in position when inserted into the bottle cap; and the sucking structure allows the use of any recyclable bottle or container and thus contributes to environmental purpose.
