Abstract: A tire/wheel structure includes a body, such as an automobile tire, and guide blocks mounted to two sidewalls of the body in a circumferentially arranged cascade series. Each guide block has a side facing a forward rotation direction of the body and forming at least one inclined guide face in such a way that the inclined guide face and an adjacent one of the guide blocks define therebetween a wind-assisting groove, whereby when the body is in a forward rotating condition, the inclined guide faces of the guide blocks and the wind-assisting grooves help enhance airflow guiding, reduce wind resistance, and generating an assistive driving force and when the inclined guide faces of the guide blocks and the wind-assisting grooves are moved to a position in a lower half of the circumference of the body, a follow-the-trend driving assisting force and a moving stabilizing effect are achieved.

Abstract: A wall mounted mixer valve with pressure balance to automatically suspend the supply of hot water once the pressure of cold water drops to prevent accidental burning by hot water is essentially comprised of a body, a pressure balance device, a ball assembly, a washer, a packing cover, a cylinder, a bonnet, a rose, and a handle; within, an accommodation slot and a water outlet are provided in a base inside the body, an water inlet is each provided respectively to one edge of two shallow grooves in the middle section of said slot and a water outlet is each provided to the external side of said two grooves; a shutoff valve is protruded from the bottom of said slot with the inner edge of said shutoff valve internally threaded; the pressure balance device is comprised of an outer sleeve, an inner sleeve and a lid with the center and both RH and LH ends of said outer sleeve each provided with a packing retainer ring, one perforated spacer slot is each provided on the wall among said three packing retainer ring, a h

Abstract: An improved pressure balance valve has a valve embodiment, a sleeve , a balance valve and a sealing cap. The balance valve is housed in the tubular sleeve which is further removably secured to the sealing cap. The sealing cap is detachably fixed to an opening of the valve embodiment so that both the balance valve and the sleeve are taken out with ease for cleansing purpose. The sleeve is provided with 3 ring grooves for housing sealing rings therein so as to effectively prevent hot and cold water from intermixing due to leakage. The balance valve is opened at both ends so as to permit water to be discharged in a better manner. Between every two ring grooves of the sleeve is defined a cold or hot water section and each water section is provided with 4 spaced cold water outer inlets or 4 spaced hot water outer inlets. The balance valve is also provided with 4 cold water inner inlets or 4 hot water inner inlets in each section divided by the partition board.

Abstract: A folding golf bag stand mounting hardware includes two legs pivoted to a top mounting frame on the bag body of a golf bag and having a respective locating frame, a spring supported between the legs, an adjustable fastening belt inserted through the loop on the locating frame on either leg and having two opposite ends fastened to the bag body, a bottom mounting frame fastened to the bag body near the bottom thereof, a constraint member fastened to the bag body and aligned between the top and bottom mounting frames, a connecting rod having a bend in the middle hung on the bottom mounting frame and two opposite ends inserted through a hole on the constraint member and then respectively hung on a respective hanging hole on either locating frame, wherein the bottom mounting frame consists of a vertical mounting plate fastened to the bag body, a curved supporting plate pivoted to the vertical mounting plate in the middle, the curved supporting plate having a stop bar at one end, which stops at the vertical mountin
