Abstract: The present invention is directed to a rainwater gutter for collecting rainwater which runs off the roof of a building. The rainwater gutter is formed by connecting two or more gutter sections, such as the outer surface of the gutter is continuous with no visible connectors. The gutter sections comprise one or more keyways running along the length of the gutter section. The keyways receive an elongated keyway for connecting gutter sections end to end.

Abstract: Embodiments of the present invention include a drainage channel comprising a first barrier for containment and a second barrier for containment. In one embodiment, the second barrier comprises a liner and a support. In a further embodiment, the support substantially secures at least a portion of the second barrier in the first barrier.

Abstract: A downspout drain collar for connecting a rain gutter downspout to a downspout attachment is provided. The collar includes a collar flange adapted to removably engage the downspout attachment. The collar includes a collar body having a top portion, a bottom portion, a transition portion connecting the top portion to the bottom portion, and an axis extending through an opening defined by the body. The collar includes at least one armature extending from the collar toward the axis when the downspout drain collar is not secured to the rain gutter downspout, with each armature configured to be moved to removably secure the downspout drain collar to the rain gutter downspout.

Abstract: A system and method are disclosed for converting channels manufactured for connection together to produce a straight conduit into channels that may be connected together to produce an effectively curved conduit. A link is described that permits the connection between two channels to be connected with an axial offset, which cumulatively allows a plurality of channels to produce a curved conduit.

Abstract: A modular fluid containment system formed of a plurality of fluid containment units and interconnecting channels. The containment units and channels may be comprised of panel units made of flexible non-porous material. The system includes brace members along selected edges of the containment units and panel units which are operative between an operative position in which the edges of the flexible material forming the containment units and panel units are held in an upright position forming side walls defining a containment or channel area and an inoperative position in which the flexible material is allowed to lie along a single plane in flat or folded condition. Connectors are provided along selected edges of the panel units to interconnect the panel units into desired configurations forming the containment system of desired shape and size.

Abstract: A cover for a drainage device, in particular a drainage channel with a channel body such that the cover can be set on an upper edge of the channel body, which comprises detent ridges that extend into the channel body and which has at least one fixing element to attach the cover to the channel body or to a frame disposed on the channel body to reinforce its upper edge, such that in a locked state the fixing element engages a recess in the channel body or frame. In order to achieve durable fixation of the cover on the channel body, while enabling the fixing element to be simple to manufacture and install, and the channel cross-section to remain free, the detent ridges comprise at least one aperture to guide the fixing element, which projects out of that aperture.

Abstract: A channel system for forming a trench is disclosed that includes a number of precast drainage channel sections and one or more alignment keys for aligning and interlocking adjacent channel sections. Each alignment key includes a base shaped for laterally bridging across a predetermined exterior portion of adjacent bottom walls of the adjacent channel sections. The alignment key also includes first and second opposed, inwardly facing jaw members shaped for longitudinally bridging across a predetermined exterior portion of adjacent first and second sidewalls, respectively, of the adjacent channel sections. Each pair of the jaw members can be carried by a respective base, and can be positioned in a lateral and longitudinal direction relative to the respective base to thereby substantially align and interlock the adjacent channel sections.

Abstract: The invention relates to a drainage device for surface drainage, in particular to drainage channels with a channel body and a frame which fits on an upper edge of the channel body, comprising an outer arm and an inner arm between which the upper edge of the channel body sits, for housing a cover. According to the invention, simple economic production and assembly of the frame on the channel body may be guaranteed whereby the frame is embodied such as to be able to be cast within the body of the channel body on the casting thereof, or alternatively, may be fixed to the channel body by means of continuous jointing to a pre-fabricated channel body.

Abstract: An eaves troughing assembly includes elongated eaves troughing members of resilient material with generally U-shaped section having a rear portion, base portion and front portion, the front portion of each eaves troughing member having a longitudinally extending recess in a front face at least adjacent an end of the member. Elongated connectors of resilient material with generally U-shaped section have a rear connector portion having an inwardly extending upper free end portion forming a recess between the free end portion and an adjacent part of the rear connector to receive an upper end of the rear portion of an eaves troughing member. The front portion of each connector member has a longitudinally extending projection in a rear face shaped for snapping engagement in the recess of an eaves troughing member.

Abstract: A portable amusement device wherein flotation of participants occurs on a continuous basis within flotation devices comprises a plurality of trough defining segments each being formed with double side walls and end walls with the double side walls defining a hollow section to permit nesting of the individual segments for shipment and storage. The trough segments are joined to one another to form a continous trough with a pump in at least one hollow section to continuously move a flotation medium throughout the trough and thus propel participants therethrough.
