Abstract: A modularly designed cleaning tool such as a pool is provided with a reinforced neck area to substantially reduce breakage during use. The cleaning tool includes a brush head, a stem assembly, and a reinforcement fitting positioned at the joint area between the brush head and the stem assembly. The cleaning tool is adapted to mate with an elongated tubular pole or handle in a manner such that the pole or handle extends into the annular space defined by the reinforcement fitting and the stem assembly. The cleaning tool also includes a brush having an elongated frame and removable corner bristles extending therefrom. In some implementations, magnetic attachments are disposed on the brush frame and are adapted to pick up magnetic debris along a surface during cleaning.

Abstract: A coupling system for securing an elongated wood member having a surface to a second body comprises a stitching body having a first end and a second end defining a length, and a first side and a second side. A first plurality of angled fastener bores is positioned generally on the first side of the stitching body, each configured to position a first side fastener element resting therein at least a first angle with respect to the surface of the elongated wood member. A second plurality of angled fastener bores positioned generally on the second side of the stitching body, each configured to position a second side fastener element resting therein at least a second angle with respect to the surface of the elongated wood member, such that ones of said second side fasteners and said first side fasteners form an intersection when viewed along the length of the stitching body. In one aspect, the coupling system is a hold-down securing a column having a surface to a foundation.

Abstract: An improved joint for a bicycle frame has a first sleeve for receiving a head tube and a second sleeve projecting laterally from the first sleeve, for receiving a top tube or a downtube, wherein the second sleeve includes an inner tube and an outer tube, which coaxially project from the first sleeve and which are spaced from each other with a circumferential clearance which is slightly larger than the thickness of the top tube or the downtube so that the top tube or downtube may be snap fit into this clearance.

Abstract: A wall bar comprising a length of tubular material the ends of which said length extend at an angle to the adjacent portions. The ends have integral flattened portions lying in a plane intersected by the inclined portions and defining an obtuse angle with the axis of the inclined portions. The flattened portions are adapted to engage a wall and be attached thereto. A cover plate is provided for each end and has an elongated opening such that the cover plate may be telescoped over the flattened portion to mount the plate on the bar after the flattened portion has been formed and the plate can be placed in position over the flattened portion after the flattened portion has been attached to a wall.

Abstract: A lock device for vehicles such as bicycles and motorcycles having tubular frames which comprises a cable or chain threaded into an opening in a frame member with a stop to prevent full extraction from the frame, and a loop or other means to receive a padlock shackle to lock the vehicle to a post or to lock the wheel of a vehicle to prevent rotation.

Abstract: A leg is coupled to one half of the connecting structure, e.g. a detachable seat, via screw engagement and the latter is coupled, via wedge engagement to be established by projections formed thereon, to the other half of the connecting structure, e.g. a fixed seat, mounted to the bottom of a massive body such as a keyboard musical instrument, a larger sized television set and a heavy table. Registration of the leg at the correct position and the above-described wedge engagement are carried out simply by sliding the one seat against the other seat with alleviated trouble in the collimation work, reduced damage on the thread construction and stabilized support for the massive body.

Abstract: A beam-type pile such as a double-T beam is secured to a sheet piling after driving a pile into the ground in a usually slanted position. The pile is secured to the sheet piling by welding a pull bar to the web of the pile so as to protrude from the head thereof. The protruding pull bar portion is partly inserted into a cutout of the sheet piling. This protruding pull bar portion is secured in the sheet piling by a support plate including a slot through which the pull bar portion is extended. The support plate is welded to the inside wall surface. The pull bar portion protruding into the sheet piling is further fastened by a reinforcing plate disposed upright relative to the protruding pull bar position and welded thereto and the support plate.
