A ride-on floor machine, including: a frame including a lower frame portion; a drive system carried by the frame; and a blade control system carried by the lower frame portion, the blade control system including: a blade holder pivotably attached proximate a front end of the lower frame portion; and a linear actuator coupled to the blade holder at a first end and coupled to the lower frame portion at a second end, wherein the actuator extends along a center line parallel to the lower frame portion and is operative to move between an extended position where the blade holder is in an up position and a retracted position where the blade holder is in a down position.

A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A tool that attaches to an underside of a rotating floor stripper machine that includes a plurality of bracket assemblies that each contain a blade assembly. The blades are equally spaced around segments of the underside of the plate. The cutting angle of each blade is selected to have a specific angle of incidence and each blade is configured askew from the radial line of the plate. Each blade assembly further includes a suspension to absorb imbalance caused by interaction with irregular surfaces during operation to greatly smooth out the machine and improve control. Alternate forms of cutting blades are provided to remove different materials and cause smoother or coarser cuts.

Demolition tools are presented including: a handle having a proximal end and a distal end, where the handle includes a reinforcing gusset mechanically coupled with the prying head, and where the handle further includes at least three bends along a handle length; a prying head disposed along the distal end of the handle, the prying head including at least two tines mechanically coupled with a cross frame; and a striking head mechanically coupled with and disposed along at least one end of the cross frame.

A tool for removing carpet from a floor. The carpet removal tool includes a panel having an elongated opening thereon. Opposing ends of the panel include handles pivotally affixed thereto to be grasped by one or more users, wherein the handles can be positioned parallel to or perpendicular to the panel. In operation, the user cuts a portion of the carpet to be removed and secures the end of the carpet within the elongated opening on the panel. The user then pulls using the handle so that the carpet wraps around the panel as it is removed from the floor. The carpet can be manually wrapped around the panel by the user.

A removable scraper device is described herein. The removable scraper device includes an attachment element and a socket defined by the attachment element, wherein the socket is configured to receive a post of a scraper element therein. The removable scraper device further includes a slot defined by the attachment element, wherein the slot is configured to receive a portion of a bucket of a wheeled-machine therein. The removable scraper device further includes an aperture defined by the attachment element and a bolt sized to be received within the aperture. In some embodiments of the removable scraper device, the bolt and aperture are configured to selectively press the attachment element against the bucket to removably secure the removable scraper device thereto.

Carpet pad removal tools may include a handle and a headplate coupled to the handle. The headplate may include a plurality of teeth along an edge of the headplate that is angled relative to the rest of the headplate. Other aspects, embodiments, and features are also included.

A floor scraper hand tool includes an elongated handle, a concave scraper blade, and a guard. The elongated handle is at least two feet long and defines first and second distal ends. The concave scraper blade is coupled proximate the first distal end and includes first and second scraping edges having different forms. A guard at least partially covers one of the first scraping edge or the second scraping edge. The concave scraper blade is coupleable to the elongated handle in a first position in which the first scraping edge is opposite the second distal end of the elongated handle and in a second position in which the second scraping edge is opposite the second distal end of the elongated handle. The guard at least partially covers the first scraping edge in the second position and at least partially covers the second scraping edge in the first position.

A raised floor panel removal tool includes a J-shaped body having a first vertical bar, a second vertical bar and a horizontal bar that is connected to the vertical bars along the respective bottom ends. A handle is positioned along the top of the first vertical bar and is positioned perpendicular to the horizontal bar. The tool components are constructed from steel tubing and an electrically insulative material is provided along the handle. A pair of wheels are attached to the bottom end of the first vertical bar by a bracket, and the second vertical bar can be constructed to include an adjustable height.

An uncoupling mat includes a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side. The annular cavities on the bottom side each define a recess on the first side. The indentations have a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations. A plurality of weakening zones each extends between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones.
