Abstract: A wave-generating watercraft includes a craft body having an installation space. A telescopic drive is mounted within the installation space. A pivot seat is mounted on the craft body within the installation space. A wave-forming block is driven by the telescopic drive to move between extended and retracted positions, and has an outside block face and an inside block face. When the wave-forming block moves to the retracted position, the inside block face is pulled by the telescopic drive, and the outside block face moves to the installation space. When the wave-forming block moves to the extended position, the inside block face rotates away from the telescopic drive, and the outside block face protrudes from the installation space.

Abstract: A wave-generating watercraft includes a craft body having an installation space receiving a wave-generating unit. A telescopic drive is mounted within the installation space and is connected to a driven unit. A wave-forming fin is connected to the driven unit and is driven by the telescopic drive to move between extended and retracted positions. The telescopic drive is aligned with a front-rear direction of the craft body and is stretchable and retractable along the front-rear direction. The wave-forming fin protrudes from the installation space when the wave-forming fin moves to the extended position and is received in the installation space when the wave-forming fin retracts.

Abstract: A waterproof container includes a bag unit, a seat unit and a cover unit. The seat unit includes a receiving seat that is disposed on the bag unit and that defines an opening. The cover unit removably and sealingly covers the opening, and includes a cover and a zipper. The zipper divides the cover into a fixed portion that is connected fixedly to the receiving seat, and a flip portion that corresponds in position to the opening. The cover is operable between a flipped state, where the zipper is unzipped and the flip portion is flipped open for exposing the opening, and a non-flipped state, where the zipper is zipped for covering the opening with the flip portion.

Abstract: A waterproof container includes a bag unit, a seat unit, a cover unit and a lock unit. The seat unit is disposed on the bag unit and defines an opening. The cover unit includes a cover, and two zippers dividing the cover into a fixed portion and a flip portion. The lock unit includes a first lock seat disposed on the fixed portion, a second lock seat disposed on the flip portion, and a locking mechanism operable between a locking state, where the locking mechanism engages the first and second lock seats so as to prevent the flip portion from being flipped open, and a releasing state, where the locking mechanism does not engage the first and second lock seats so as to allow the flip portion to be flipped open when the zippers are unzipped.

Abstract: A grill includes upper and lower plates and heat conducting members. The upper plate includes alternating ridge and furrow portions, and is formed with alternating receiving spaces and first connecting surfaces. The heat conducting members are disposed in the receiving spaces, respectively. The first connecting surfaces are provided at the respective furrow portions. The lower plate includes alternating and interconnected first and second plate portions. The first plate portions respectively correspond to the ridge portions . The second plate portions have second connecting surfaces and second holes registered with first holes formed in the furrow portions. The furrow portions are welded to the second plate portions with the first and second connecting surfaces being in intimate contact.

Abstract: An auto/manual gas inflator incorporating a gas cylinder and an auto cap. A first indication mechanism is provided for indicating the status of the gas cylinder which is visible through a first window in the inflator housing and a second indication mechanism is provided for indicating the status of the auto cap through a second window in the inflator housing. The auto cap in one embodiment uses a dissolvable pill for automatic inflation. A manual activator, such as a lanyard assembly can be used for manual inflation. In either activation method, a pierce pin is moved upward to break the cylinder's seal and release the gas contained within the cylinder.

Abstract: A manual gas inflator incorporating a cylinder status indication mechanism that is independent from the cylinder piercer. Prior to detonation, an indicator post abuts a sensor protrusion which positions a green surface of the indicator within the inflator window to indicate that the attached cartridge is ready for use. The jerking of a lanyard assembly causes the piercer to break the cylinder seal to allow gas to escape out of the cylinder and into a manifold secured to the inflator and also causes the indicator post to break the sensor protrusion from the cylinder. As the protrusion is broken, a second red surface of the indicator is viewable through the inflator window to indicate that the cylinder has been used and unavailable for inflation purposes.

Abstract: A grill apparatus includes: a housing; a grid disposed in the housing; a heating unit disposed below the grid within the housing for generating heat; a grease-collecting tray disposed below the heating unit; a grease-guiding tray disposed between the heating unit and the grease-collecting tray and formed with a central hole for passage of grease therethrough and into the grease-collecting tray; and a cover connected to the grease-guiding tray, covering the central hole in the grease-guiding tray, and cooperating with the grease-guiding tray to define a gap therebetween. The gap is in spatial communication with the central hole.

Abstract: A water pipe connector includes a pipe coupling portion surrounding an axis and adapted to be sleeved on one end of a water pipe, a clamping component having resilient arms that extend between the pipe coupling portion and the water pipe and that have engaging members projecting through radial holes in the pipe coupling portion, and a locking collar. The locking collar is sleeved on the pipe coupling portion, has an internal collar surface formed with a plurality of first grooves, and is rotatable about the axis between an unlocking position, where the engaging members are received respectively in the first grooves, and a locking position, where the internal collar surface abuts against the engaging members and urges the resilient arms to abut tightly against the water pipe so as to arrest removal of the water pipe from the pipe coupling portion.

Abstract: A fishing rod includes a hollow butt section and a solid tip section. The butt section has an inner surface that defines an inner space. The tip section has an inner segment that extends into the inner space and that is bonded adhesively to the inner surface of the butt section, and an outer segment that extends from the inner segment and that is disposed outwardly of the inner space.

Abstract: An athletic protective gear includes a protective structural member, a protective pad, and a retainer unit. The structural member is formed to overlie a body part to be protected. The protective pad of depressible material is formed to be disposed between the protective structural member and the body part and has two openings formed therethrough. The retainer unit includes a fastener strap secured on an inner surface of the protective structural member and has two opposed end portions which respectively extend through the openings of the structural member, and two hook-and-loop elements which are secured to the end portions respectively and which engage each other in such a manner that the protective structural member abuts against an outer side surface of the protective pad, thereby retaining the end portions of the strap on an inner side surface of the protective pad. Thus, the protective pad is confined between the structural member and the body part.

Abstract: A protective pad for an athlete includes an improved securing means to releaseably secure a structural member and a pad, wherein the securing means includes a headed stud and a narrow elongate fastening opening to engage with the stud. The fastening opening has an enlarged portion for easy access by the head of the stud and an angled remaining portion for positioning the stud.
