Abstract: An improved opening lock for use in a sunshade or a parasol which is housed in a cavity defined on the shaft of the sunshade. The present opening lock has a stop block having a smoothly curved guide bottom at the front end and a bias spring disposed behind the stop block and a fixing element for mounting the spring, and a cover plate which confines the stop block and the spring and the fixing element inside the cavity so that the runner of the sunshade slidably disposed on the shaft is able to move against the lock, pushing the lock into the cavity when the runner traveling upward to make the sunshade open, and the stop block is able to pop out when the runner passing the same and to support the runner in place, keeping the sunshade opened. To close the sunshade, the stop lock must be pushed into the cavity to permit the runner slide downward.
Abstract: A unique platform performs several functions in the installation of planar flooring. The platform has a planar top face and a pair of wheel sets on an underface. In a first function the platforms are used in groups of two, and positioned with the wheels extending upwardly and spaced from each other such that the axis of rotations of the sets of wheels on the two platforms are generally parallel and aligned. A coil of planar flooring material is placed on the spaced platforms, such that the planar flooring material may be removed from the coil with the wheels turning to aid in the removal and protect the surface of the flooring. After the planar material is removed and has been adhesively applied to a floor, the platforms perform a second function. They are reversed and a force is applied to the platform such that the wheels roll along the planar flooring and cause the adhesive to wet and firmly secure the planar flooring to the underlying floor.
Abstract: A multi-layer shingle is provided, comprising three shingle layers; specifically, a base layer, a secondary layer and a top layer. The base layer and the secondary layer each have butt portions and tab portions. The secondary layer has tab portions that are preferably somewhat shorter than the tab portions of the base layer, showing portions of the tab portions of the base layer beneath the tab portioins of the secondary layer. The top, or third layer is comprised of individual strips that are preferably narrower than the tab portions of the secondary layer, and which preferably extend up into the butt portion of the secondary layer, in overlying relationship therewith. The base layer and secondary layer are secured together by preferably horizontal adhesive stripes. Adhesive also secures the top or third layer strips to the secondary layer, preferably by means of vertical adhesive stripes. Different granule applications are provided for desired aesthetic effects.

Abstract: A climatic heat aircraft protective (CHAP) screen that has been designed to protect various types of aircraft, and especially helicopters, from the adverse effects of direct exposure to sunlight while being relatively insensitive to wind conditions. The CHAP screen is specifically designed for various aircraft types to facilitate easy and rapid deployment and removal of the CHAP screen utilizing only the flight crew of the aircraft. The CHAP screen includes a porous screen canopy having overhanging portions and flap portions that are operative to reflect direct sunlight while allowing air to pass therethrough. The CHAP screen also includes a containment bag affixed to the underside of the porous screen canopy that is used to compactly stow the porous screen canopy prior to deployment and to secure the CHAP screen to the rotor head assembly of a helicopter during deployment.
Abstract: A multi-level parking lot made from prefabricated reinforced concrete modular elements is disclosed. The modular elements include plural parking compartments with defined paths for passage between the compartments and approach routes for entering the parking lot. The parking compartments include connecting plates and integral units with four columns, each integral unit including a slab integral with and resting on the four columns. A steel pipe protrudes from an upper surface of the column for interfitting engagement with a corresponding hole in the connecting plate. The individual units bear against themselves in a stable manner by virtue of their weight without the need for any linking connections therebetween.
Abstract: A rain water collecting device for an umbrella includes a reservoir (6) with a closed end and an open end. A diaphragm (10) is mounted in the reservoir (6) adjacent to the open end to separate the reservoir (6) into a first compartment (62) and a second compartment (64). A receiving member (5) is mounted in the center of the diaphragm (10) and extends into the first compartment (62) for removably receiving a tip of the umbrella. A first coil tube (8) mounted in the first compartment (62) has a inlet (3) located at the diaphragm (5) and an outlet (4) in the first compartment (62). A second coil tube (9) mounted in the second compartment (64) has an inlet (1) located at the diaphragm (5) and an outlet (2) in the second compartment (64). When the umbrella is folded after use, the rain water is guided into the first compartment (62) via the first coil tube (8).
