Abstract: The invention relates to a telescopic staircase to be installed on construction sites for providing a safe staircase for workers during building construction. The telescopic staircase comprising at least one lateral guard comprising a top rail, a bottom rail and at least two newels, the bottom rail having a plurality of connecting holes, and a plurality of tread assembly comprising a tread plate, at least two stringer portions and at least two pairs of support members, each support member having at least one connecting hole, in which the at least one lateral guard includes a first portion being retractable into and extensible from a second portion, in which each support member substantially forms a 45° angle with the tread plate, and in which the support members are to be attached to the top surface of the bottom rail via attachment means through the connecting holes.

Abstract: A drilling hole correction tool having an internal push rod; an external guide cylinder, a shear pin: an internal locking pin; and a foot. A method for correcting drill hole comprises: raising the rods to 3.0 m above the bottom; removing inner tube from drill string: deploying adhesive into the bottom below drill bit; lowering hole correction tool down drill string until landing ring readies landing shoulder and the latches are deployed: setting the desired orientation; lowering the drill string to press the external guide cylinder into the adhesive until the external guide cylinder reaches the bottom of the hole, shearing the shear pin; further lowering the drill string 6 to 8 inches until the drill string is loaded: clamping external guide cylinder in place; allowing adhesive to cure; retrieving back end and internal guide rod from drill hole; and lowering original standard inner tube down drill string.

Abstract: A multipurpose cleaning device is disclosed which is designed to achieve a high degree of surface coverage in any direction with each brush sweep so that cleaning surfaces, such as vehicles, may be performed fast and easy. The shape of the brush head provides maximum area coverage on each sweep and minimizes the tendency of the brush head from tipping during a sweep when connected to a main handle and a pivoting head feature minimizes the need of bending. Embodiments includes versions optimized for both washing that including channels for the introduction of water and liquid soap as well as to received drying members.

Abstract: A portable pet excrement collector for use in association with a disposable bag is disclosed to manage pet excrement. The collector includes a collapsible reach extending body with a pair of bag supporting pivoting arms at a distal end of the body. A rotational stop is provided and is associated with each of said pivoting arms. At least one pivot element pivotally attaches each arm to said body, and said pivot element is sized and shaped to permit the bag supporting pivoting arms to pivot between a first lower open position in which the pivoting arms extend out from said body and a second raised position in which the pivoting arms are generally parallel to the body and adjacent to one another. The rotational stop supports the pivot arms in the lowered position, wherein a bag supported on said pivot arms is placed in an open position when said arms are lowered and a closed position when said arms are raised.
