A self drilling toggle anchor including an anchor member having a head portion at a proximal end, a locking portion at a distal end and a central portion for securely anchoring hardware to a wall, where the central portion defines and borders a channel between the head portion and locking portion. The toggle anchor also includes a drilling member positioned at a distal end of the toggle anchor for drilling through the wall and a toggle member. The toggle member includes a body disposed within the channel of the anchor member, a fitting portion disposed between the body and the drilling member, and upper and lower pairs of shoulders supporting the body within the channel. The body is slidably mounted to the anchor member within the channel and the fitting portion is adapted to releasably engage the locking portion allowing the toggle member to be movable from a releasably locked and fixed first position parallel with a longitudinal axis of the channel to a second position orthogonal to the channel.

The present invention relates to a repair clamp providing an improved pipe repair clamp. The clamp according to the invention could be used in some cases as a coupling to join two pipe ends.The clamp comprises;a) a metal clamping band to surround 3600 of a pipe. The band being extended at both ends to form a hollow shape including a flat base, a wedge-shaped section and a convex rounded section, elongated apertures being provided to allow passage for screw fasteners through the hollow shape, narrow edges of the wedge-shaped sections being in contact with each other to form a substantially triangularly shaped space between the formed ends; and a flexible inner sealing sleeve disposed inside the clamping band and a pair of profile strips each having a major face for contacting the outer surface of the convex rounded section, and an opposite seating face for shoulder support of a plurality of screw fasteners, the strips having apertures to allow passage of the fasteners, and a plurality of screw fasteners inserted into the apertures wherein the tightening of said screw fasteners reduces the size of the triangularly shaped space and tightens the metal clamping band to compress the flexible inner sleeve sealingly against the outer diameter of the pipes.

The invention specifically relates to a front and back overturning apparatus, and belongs to the technical field of sports apparatuses and instruments. The apparatus comprises a rolling frame, a seat and a shoulder supporting device; the seat and the shoulder supporting device are arranged in the rolling frame; the shoulder supporting device is positioned right above the seat; the rolling frame comprises two steel wheels, and a connecting cross bar between the two steel wheels; the seat comprises a backrest, a seat board and supporting legs. According to the apparatus, the rolling frame rolls to drive a practicer in the seat to practice overturning front and back; in addition, the shoulders are fixed through the shoulder supporting device, so that the neck does not bear any pressure from the body during overturning front and back, and as a result, the neck can be effectively protected; the apparatus has a good front and back overturning effect and free of the phenomena of inaccurate direction and failure of overturning.

A portable, user shoulder supported spreader / blower unit includes an ergonomically configured housing which includes a section defining a storage bin for holding a quantity of salt or like chemical particulate material for spreading onto ground surfaces to prevent icing thereon in winter. A centrifugal distributor disk is located in a housing space section below the bin and, a bin discharge aperture aligns over a peripheral area of the distributor disk. A user controllable closure member selectively alters bin discharge aperture size and, hence, outflow quantity from the bin onto the distributor disk, the distributor disk rotating at high speed propelling particulate material out of the housing through a discharge nozzle thereon at a high speed. e.g., 60 m / sec when the unit is user in a spreader mode. To further enhance carry of the particulate material from the housing, a fan impeller mounted in the housing in the common space wherein the distributor disk operates, is rotated at high speed to produce air flow supplementing energy imparted to the particulate material. When the unit is used in a blower mode such as in a leaf collection operation, high pressure air from an outside source can be introduced into the unit so the airstream discharge from the unit is optimized to that required for leaf blowing.
