Abstract: A pipe coupling may include a body that is tubular and formed from a polymer. The body may include a main bore with a main axis and at least first and second female receptacles on each end of the main bore. Each receptacle may be configured to receive a male end of a pipe. A first brace may be coupled to and extend between, for example, a first female receptacle and a third female receptacle. A second brace may be coupled to extend between, for example, a second female receptacle and the third female receptacle. The pipe coupling can be a single, integral, injection molded monolithic structure.

Abstract: A pipe may include a pipe body having an axis, an axial bore and a pipe body outer diameter. A male end may be formed on the pipe body. The male end can have an outer diameter consistent with the pipe body outer diameter, and an axial end face. A female end may be formed as an integral bell on the pipe body opposite the male end. The female end may have an inner diameter that is larger than the outer diameter of the male end, a seal recess on an interior thereof, and an interior feature in the interior of the female end that is complementary to the axial end face of the male end. The female end of a first pipe may be configured to receive the male end of a second pipe, such that the interior feature of the first pipe engages and restrains the axial end face of the second pipe. A coupling may be used to join two of the pipes.

Abstract: A system for a basement concrete form and drainage are disclosed. The system may include a lineal that is a horizontal concrete form for a footer for a wall and a basement floor. The lineal may include a rectilinear tubular structure having a cavity, an outer wall, and drain perforations in the outer wall to permit fluid transmission from the cavity to an exterior of the lineal. In addition, a retainer may be mounted to a stake for the basement concrete form when the stake is embedded in a formation underlying the lineal. The retainer may be selectively vertically positioned along the stake to adjust a height of the lineal relative to the underlying formation.

Abstract: A juvenile product includes a frame, a hub assembly mounted on the frame and including first and second hubs, and first and second seat supports coupled to the first and second hubs, respectively, for pivotal movement between an in-use orientation and a folded orientation. The first hub includes a cam to release the first and second seat supports for the pivotable movement toward the folded orientation in response to rotation of the first seat support.

Abstract: A stroller assembly has a frame assembly with a front and a back. The stroller assembly also has a handle coupled to the frame assembly and positioned near the back of the frame assembly. The handle has a central section between a pair of side sections and the side sections extending further rearward than the central section relative to the back of the frame assembly.
