The hollow pipes have receiving holes each housing a clamping bead, and the bead can be pushed outward. The two link connectors each has a plurality of clamping hole; and the two hollow pipes are pivotally arranged on the two link connectors such that the main body can be rotationally adjusted and the bead can be moved outward and fixed on the clamping hole to clamp the main body.

Abstract: A skating scooter includes a deck with a rear wheel and a handlebar assembly pivotally connected to two protrusions on the deck. A front wheel is connected to a lower end of the handlebar assembly and a handlebar is connected to a top of the handlebar assembly. The handlebar has two pivotably grip portions. A bolt and a pin respectively extend through the two protrusions and are engaged with a groove in the handlebar assembly. The handlebar assembly can be pivoted toward the deck by respectively removing the bolt and the pin from the groove in the handlebar assembly.

Abstract: A handle device includes a tube, a seat secured to the tube and having a channel for slidably receiving one end of one or more hand grips. The hand grips each has a slot for slidably receiving a fastener which is engaged through the hand grips and for allowing the hand grips to be folded to a compact folding position. The fastener has a neck engageable into the hand grip for solidly securing the hand grips to the seat. A bar is engaged onto the hand grip, and a quick release fastener is engaged through the bar and secured to the seat for clamping the bar to the hand grip.

Abstract: A portable carrying case for a laptop computer is disclosed which may be readily converted into a rolling case. This conversion is accomplished with minimal additional weight or bulk, by a retractable handle which extends into, and through, the interior of the case, and while not in use, may be disconnected from the case. A narrow elongated roller is mounted along the bottom edge of the laptop carrying case for transporting the case along the ground surface. The narrow elongated roller may also be removed from the case when it is desired to utilize the case in a non-rolling mode of operation.

Abstract: A scooter includes a handlebar having a lower portion slidably and pivotally secured to a board with a shaft. A rod is secured to the handlebar and biased to engage with either of two depressions of the board for securing the handlebar to the board at either an upright working position or a downward folding position. A lock device may selectively engage with the board and the handlebar to for lock the handlebar to the board at either the upright working position or the downward folding position, for preventing the handlebar from being folded relative to the board inadvertently.

Abstract: Disclosed is an automatic semiconductor wafer applying apparatus capable of lightly easily stacking and loading ring frames onto a frame supply section. This apparatus has the following construction. An adhesive tape unwound from a tape roll is applied to a lower surface of the ring frame supplied to a tape applying position. The applied adhesive tape is cut out along the ring frame. The ring frame having the adhesive tape applied thereto is transported to a wafer applying position. A semiconductor wafer is applied onto the adhesive tape of the ring frame. In this apparatus, a frame supply truck movable with the ring frames stacked and held thereon is arranged so that it can be pushed/transported into and pulled out/transported from the frame supply section. A lift unit for receiving, lifting and supplying a group of ring frames stacked on the pushed and transported frame supply truck is installed in the frame supply section.

Abstract: An improvement of the pop-up mechanism for an extendable handle of wheeled luggage is disclosed. The popup mechanism comprises an additional elastic device in the overlaying section of the sliding tube and the support tube for cooperating with a first elastic device and a fastening device. Once the push button is pressed by a hand the sliding tube locked by the pin of the push button is unlocked and thus the sliding tube moves downward a predetermined distance. In this manner, the hand pressing the push button previously will be able to leave the push button unattended. Then use the same hand to push down the sliding tube to its lowest locked position. As a result, the purpose of retracting the handle by a single hand is fulfilled.

Abstract: A skate cart includes a board with a front wheel and a rear wheel. A handlebar stem is pivotally connected to a connection port extending from a front end of the board and the front wheel is connected to the handlebar stem. The connection port has two lugs and a lower end of the handlebar stem is engaged between the two lugs. A rod is movably inserted through one of the lugs and a passage in the handlebar stem. When pulling the rod out from the passage in the handlebar stem, the handlebar stem is pivotable relative to the board.

Abstract: A luggage handle structure includes a handle, two inner tubes, two linking rods, two inner locking tubes, and two outer tubes. The handle includes an upper cap having a mediate portion defining a hollow recess and two sides each defining a cut slot, the hollow recess having two sides each formed with a hollow lower lug; a press plate having a mediate portion defining a chamber and two sides each formed with a protruding wing received in the cut slot of the upper cap, the protruding wing defining a through hole for receiving the lower lug of the upper cap, a spring received in the chamber; and a base having two sides each formed with an insertion block received in the cut slot of the upper cap and a hollow upper lug formed on an inner side of the insertion block, the upper lug aligning with the lower lug, a bolt extending through the upper lug and screwed into the lower lug to form a retaining column, a stub formed on the mediate portion of the base and attached to the spring.

Abstract: A folding front support for a skateboard, in which the front support has a longitudinal groove at two sides near the bottom end including an expansion ring at the top and middle positions. Two pivoting ears each with a throughhole are fitted on the connection part between the frame and the front support. A turning pin with an oval member is inserted into the throughholes of the pivoting ears, and a fixing effect will then be created by means of a fixing ring. A deep groove is disposed between the pivoting ears so that the front support whose outer diameter is smaller than the inner diameter of the deep groove can be plugged into the deep groove in a telescopic state for adjusting the upright height of the front support. Furthermore, the front support can be folded in direction toward the rear side of the frame.

Abstract: A combined handrail-and-frame structure of a baby stroller includes an assembly and an engaging seat wherein the assembly 8 includes an inner seat, a first fastener, a second fastener, a spring, and a housing. A hook with a lead inclined surface is provided in each of the first and second fasteners, and a convex push button is provided at the top of the second fastener. Moreover, a positioning head having an engaging fork is provided at an end of the assembly, and a spring installed in between the first and the second fasteners is also provided. In addition, a slit for clipping the engaging fork and an opening having a first and a second edge is provided in the engaging seat to be hooked up by the hooks for positioning the engaging fork in horizontal and vertical directions. When it comes to detaching, the push button is press to compress the spring, and the two hooks will be unlocked such that the assembly can be separated from the engaging seat.
