Abstract: Disclosed herein is a stock bar and T-bar coupling structure for mounting a sprinkler. In the present invention, a locking bracket is easily securely coupled to a T-bar using an elastic locking unit and a wing bolt. Furthermore, a stock bar made of standard rectangular pipe is coupled to the locking bracket by a first locking unit such that the stock bar crosses over the T-bar. Because this locking bracket is manufactured as a separate component from the stock bar, the present invention can be used without limiting the distance between the T-bars. Furthermore, the present invention has an advantage in that a standard rectangular pipe can be easily used as a stock bar merely by cutting the pipe to a desired length.

Abstract: An improved crossarm support bracket for preventing excessive bending and breakage at the midsection of crossarms caused by conventional horizontal brackets and supporting heavier crossarms. The improvement comprises a base portion for attaching the bracket to a utility pole, a pair of spaced apart flanges for supporting a crossarm, and a pair of arcuate mounting seats providing contact surfaces with outer edges of the crossarm to minimize deformation of the crossarm. By assuming a bowed position along the curvature of the seats, the arcuate shaped seats eliminate point pressure exerted by outer ends of conventional horizontal brackets which act as wedges against a crossarm receiving the combined weight of the distal ends of the crossarm. Mounting seats further minimize deformation of the crossarm by contacting the crossarm at its outer edge rather than the entire surface area.
Abstract: A connector for a main tee of a suspended ceiling grid that has improved self-aligning and connection force properties. The connector has an end tab with a forward portion bent at a lead angle and a receiving pocket with an outwardly flared entrance that, with an opposed identical connector, cooperate to provide smooth horizontal alignment. The end portion, additionally, includes an edge profile that vertically aligns itself with the receiving pocket of the opposed connector. The receiving pocket includes a spring-like resilient wall that limits the assembly force to overcome interference with projecting lock lances even when the connectors are nearly out of dimensional tolerance. The spring-like pocket wall, shape of the lock lance, and reinforcing beads contribute to an improved audible click signaling that a connection has been completed. The lock lance works with a relief groove to augment self-alignment of the connectors.

Abstract: Skeletal railing systems are usually formed of metal tubing welded together and/or interconnected by metal T-connectors, cross connectors and elbows. The assembling of such railing systems is often time consuming and expensive. A simple alternative includes tubular plastic, preferably polyvinyl chloride posts and rails interconnected by short lengths of metal tubing which extend through openings in the plastic tubes. A bolt perpendicular to one section of metal tubing extends into a plate or plug on the end of the other section of metal tubing, and a nut is tightened onto the bolt to hold the sections together.
Abstract: In an interlocking beam construction in which hollow beams are notched and interlocked to define a completely rigid joint without fasteners, reinforcement inserts are slid into the beam to the notched area. The inserts are notched to conform to the notches in the respective beams so that the interlocking function of the beams is accommodated, but the weakness that would otherwise be produced at the joint due to the notching of the otherwise hollow beams is eliminated.
Abstract: A unit of child's furniture such as a chair or sofa is constructed of intersecting panels provided with a unique interlocking joint which provides strength, rigidity and long life to such furniture. In one form, each panel is made of a pair of triple wall corrugated cardboard sheets which are individually slotted and channeled to provide different portions of its joint, and which thereafter have their sides cemented together to form a double thickness corrugated panel. The furniture is preferably made so it can be transported and stored in flat, knockdown condition and assembled when needed.
Abstract: An end connector structure for suspension ceiling grid systems provides a connector to connector lock on each side of the web of a through runner. The lock includes a lateral tear drop shaped protrusion providing a rearwardly facing exposed edge in combination with a lateral strap on an associated identical connector which also provides a rearwardly facing exposed edge. When tensile stresses are applied between the two connectors, the connector to connector lock is subjected to forces causing the associated rearwardly facing edges to engage and resist connector separation. The protrusion joins the adjacent portion of the connector material with bends having relatively large radius of curvature to reduce the weakening of the structure of the protrusion resulting from notch sensitivity. These large radius of curvatures result in substantially improved ultimate strength in the connector to connector lock when compared with protrusions formed with relatively sharp bends.
Abstract: A suspended ceiling support system is formed of a grid having main runners (12) interconnected by cross runners (16) extending at right angles to the main runners and abutting the main runners at runner intersections. The cross runners are firmly and fixedly interconnected to one another and to the interposed main runner by means of a single connector clip (20) of uniform height throughout its length. The connector clip has end plates (120,124) that connect to opposite sides of the webs (34,144) of respective cross runners and an integral angulated intermediate section (140) extending through a vertical slot (110) in the main runner web (106). The cross runners are formed with opposing channels (40,52,42,54) that slidably receive upper and lower edges of the connector clip and each cross runner web has a hole (99) to receive a locking tongue (126,128) on the clip. Thus a single connector clip firmly and fixedly connects ends of two cross runners to each other and to the interposed main runner.
Abstract: Pipe fittings that allow pipes to intersect each other without communication, and without extending one pipe over and around the second one. The use of these fittings allow installation of intersecting pipes in two dimensions. The angle of intersection can be varied up to 90 degrees, or perpendicular. The use of these fittings save material expense, labor expense, time and space, and improve pressure loss compared to current methods of piping.
