Abstract: A wood flooring adjustment and assembly tool includes a stationary flat bar having a distal end provided with a downwardly oriented lip, a guide statically attached to a top surface of the flat bar and located proximally of the downwardly oriented lip, a dynamic bar slidably positioned through the guide and linearly reciprocated along the stationary flat bar wherein the dynamic bar has a plate affixed to a distal end thereof, and a lever having a bottom end pivotally positioned at a proximal end of the stationary flat bar and directly abutted against a proximal end of the dynamic bar. Such a lever is pivotal about a fulcrum axis registered orthogonal to the proximal end of the stationary flat bar. The downwardly oriented lip is registered orthogonal to a longitudinal length of the dynamic bar and parallel to the flat bar.

Abstract: A tile leveling system includes an anchor member arranged to be positioned in a setting bed below adjacent tiles. A tensioning member extends upwardly from the anchor member and is arranged to pass between the adjacent tiles. The tensioning member is made of a metallic material and frangibly connected to the anchor member via a breakage point. A loading system is arranged to be positioned on top of the adjacent tiles and includes a drive mechanism. The drive mechanism is connected to the tensioning member and is selectively operable to secure and level the adjacent tiles between the anchor member and the loading system.

Abstract: Disclosed is an auxiliary device (1) for alignment of floor boards (2) when laying plank flooring. The auxiliary device is a tensioning unit (10) with two floor-side, protruding, lower contact jaws (12, 14) for resting against board side edges. The contact jaws are joined together via a displacement guide (16) for changing of their mutual internal distance (X1, X2), and with an upper lever mechanism (18) positioned opposite the lower, floor-side contact jaws (12, 14). The lever mechanism (18) is designed according to the toggle principle and is connected to the contact jaws (12, 14) such that by pivoting of the lever mechanism (18) the contact jaws (12, 14) can be moved from a starting position with a larger distance (X1) into a tensioned position with a smaller, defined distance (X2).

Abstract: A flooring installation tool includes a base having a bottom surface configured to engage a top surface of a flooring material, and a shoe having a connection portion and a vertical surface engaging portion. The connection portion is movably connected to a gear housing supported by the base, and the vertical surface engaging portion is configured to engage a vertical surface of the flooring material. An adjuster is configured to selectively hold the shoe relative to the base in a first position or in a second position that is different from the first position.

Abstract: Jack-type tools for moving elements such as flooring elements by pulling and, alternatively, by pushing are shown and described. In an embodiment, the jack includes a base, a puller pivotably attached to the base, a ram extendable from the base, and a ram-drive mechanism in power-transmission relationship with the ram which is operative to extend the ram. The pivotably attached puller contacts a flooring element side portion during a pulling mode of operation and pivots out of the way so that the jack can push a flooring element during a pushing mode of operation. The ram extends from the base against a fixed surface such as a wall or cabinet to apply a force which pulls the flooring element with the puller to move the puller and flooring element away from the fixed surface and, alternatively, a force which pushes the flooring element by extension of the ram with the tool secured with respect to a subfloor or other support.

Abstract: Described are powders for use in the production of three-dimensional structures or molded bodies by means of layered manufacturing methods, and methods for the economical production thereof. The powders have the particularity that they have a good flow behavior, on the one hand, and that they are simultaneously configured such that the molded body produced with the powder in rapid prototyping has substantially improved mechanical and/or thermal characteristics. In accordance with a particularly advantageous embodiment, the powder comprises a first fraction that is present in the form of substantially spherical powder particles and that is formed by a matrix material, and at least one further fraction in the form of strengthening and/or reinforcing fibers that are preferably embedded into the matrix material.

Abstract: An improved method and apparatus for urging a flooring strip into close or tight engagement with the adjacent flooring strip, which has already been fixed into position, and holding the flooring strip securely in position for nailing or otherwise fixing the flooring strip. The invented device has a base plate with having holes therein for attachment to a floor (subfloor), a rack and pinion gear arrangement where the rack has an angle iron style pusher-puller ram pusher at the end of the rack, the end of the base plate having a removable shoe, and a rack housing situated on the base plate with an associated pinion gear engaging the rack and operated by a levering handle for urging the flooring strip into position for installation.

Abstract: A tree pusher for safely felling trees. The tree pusher controls and determines the direction in which the tree falls, using a base, a frame, a detachable head which engages the tree trunk, and an extendable screw-type trailer jack that is repairable/replaceable during operation and capable of bearing the weight of a large tree, for urging the frame and the head against the trunk of the tree. For use on uneven ground, the tree pusher is provided with a base extension. A chain is used to connect the base of the tree pusher to the trunk of the tree, to prevent movement of the base when the jack is activated. The tree pusher can be readily moved to the job site, and can be used on any type of terrain, including hard surfaces, and for any type of tree, including trees with rotten wood.

Abstract: The device comprises fixation members to be fixed onto the batten, a rod selectively driven in translation with respect to the fixation members, parallely to the batten, a push member which is fixed onto one end of the rod, and driving members that are rigidly connected with said fixation members for driving the rod according to a longitudinal axis of the rod in an advance direction for which the push member is arranged before the rod. The fixation members comprise a cramp forming stirrup which is fitted with a screwable block for adapting a transverse size of the stirrup to the width of the batten, and a knuckle member for selectively fixing the stirrup on the batten.

Abstract: A telescoping support has at its actuating head at which a roller engages a bar which emerges from the outer tube, a sleeve-like extension provided with a pawl which can engage the bar in a sleeve-locking manner under load to prevent spontaneous contraction of the support upon rupture of the roller.
