One of the cutout sections includes a slot communicated with the compartment of the lock core housing. A lateral inner wall that defines a portion of the compartment of the lock core housing includes a protruded edge. A lug retainer is mounted in the cutout section having the slot. The lug retainer includes a first end retained in the cutout section having the slot.

Abstract: A key ring assembly containing a laser indication and various cutters includes a body, an upper cover, a metal plate, and a base. The upper cover is disposed on the body, and a battery unit, a press button, a laser generator, and a replaceable lens frame are disposed in a space defined between the upper cover and the body, whereby laser beams conveying different meanings are emitted. One side of the base is provided with a plurality of insert grooves adapted to receive a plurality of different lens frames. Four elastic curved arms, a file, a pen blade, and scissors are pivotally provided on the metal plate. Each of the file, the pen blade, and scissors is provided with a retaining slot at a rear end thereof to be positioned and retained on the elastic curved arms.

Abstract: A handle assembly (10) for a floor maintenance machine (12) includes a hollow handle pole (26), a handle (84) formed of a foamed polymer, and a device (36) for adjustably locking the handle pole (26) relative to the housing (14) of the floor maintenance machine (12). The locking device (36) includes a foot-operated lever (44) of a stamped, generally U-shape. The handle (84) is formed of a top section (90) and a bottom section (92), with hand grips (156) being integrally formed solely with the top section (90). Pivotable triggers (120) are pivotally mounted to cylindrical pivot bosses (118) formed in the handle (84), with unintentional pivoting of the triggers (120) being prevented by a slideably mounted, lock-out device (164). Trapezoid-shaped extensions (106) are formed on the bottom section (92) and include edges (108) for abutting with the floor when the handle assembly (10) is tipped to reduce the risk of the handle (84) cracking at the upper end of the handle pole (26).

Abstract: A rotary and rocking toy device has four bottom seats, four roller wheels, four support frames, and four carriers. The support frames are connected together to form a cross shape. Each roller wheel is disposed on the respective bottom seat. Each support frame is connected to the respective roller wheel pivotally. Each carrier is connected to the respective support frame stably.

Abstract: Roofing kettle apparatus for heating asphalt includes a wheeled chassis mounting a vat and a heating system for heating the vat. The heating system includes a solenoid operated valve for controlling the flow of fuel gas from a fuel gas source to each of a pair of burner nozzles and a igniter assembly having an outlet adjacent the outlet of a first combustion chamber. An igniter generates a spark to ignite gas discharging from the igniter assembly outlet. A flame sensor adjacent to the first combustion chamber outlet end senses the burning of fuel gas. The igniter assembly has a second outlet adjacent the second combustion chamber outlet end. The ignition of fuel gas discharging from the igniter assembly ignites the gas discharging through the combustion chamber outlets. The burners extend into the combustion chambers.

Abstract: A golf exercise stand has a main body, two lateral plates, a sensing device, and a flagpole. The main body has a recess hole, a display screen, a groove, two lateral notches, and a rift. The flagpole has a tube inserted in the recess hole, a joint having an L-shaped block and a shaft supporting the L-shaped block, a post receiving an upper portion of the shaft, and the tube having a center hole receiving a lower portion of the shaft. A U-shaped clamp device is disposed on the L-shaped block. The U-shaped clamp device has an inner periphery groove receiving a light-emitting device and a through hole receiving a bolt. A switch is disposed on the light-emitting device. A nut engages with the bolt. Each lateral plate has a clip end engaging with the respective lateral notch, and a positioning device disposed on the lateral plate.

Abstract: A lock assembly includes a lock body having a first end portion with a lock member mounted therein, a mediate portion containing a lock hole therein, and a second end portion containing a receiving channel having a closed side and an open side, a cable detachably extending through the receiving channel and having a first end portion formed with an eye, and a second end portion formed with a snapper slidably inserted into the lock hole and detachably locked by the lock member, and a tubular retaining sleeve slidably mounted on the lock body to restrain the cable and containing two radially opposite openings defined in the bottom thereof each for receiving the elongated cable therein.

Abstract: A suitcase handle device has a positioning seat disposed in a top portion of the suitcase, a grip seat disposed on the positioning seat, a grip disposed on the grip seat, and a press plate disposed in the grip seat. The positioning seat has a first square recess and a second square recess.
