Abstract: Infinitely adjustable shelving including a vertically elongated standard having a vertically elongated outwardly facing slot therein, a U-shaped bracket positionably mounted on the standard and being horizontally elongated with the proximal end (nearer the standard) being equipped with upper and lower connection means which are arranged to provide a locking force on the standard in conjunction with an intermediate protuberance on the bracket.

Abstract: A latch incorporates a latch member in the form of a leaf spring which is connected by an overcenter operating lever mechanism to a case mounted to a door for latching engagement with a strike mounted to another door or frame member. The strike incorporates guide rails for guiding the latch member into engagement with the strike, and the case includes an upstanding part for receiving a part of a lock with another part of the lock extending through an opening in the lever mechanism.

Abstract: A hanger bracket for the split rail of a horizontal sliding door assembly is provided with an aperture into which a dependent tab on a flashing support bracket extends, and a resilient tongue on the flashing support bracket fits under the hanger bracket to removably attach the flashing support bracket to the hanger bracket.

Abstract: The present invention relates in general to combination padlocks of the type which permit the user to reset the combination, and it relates in particular to a new and improved mechanism for preventing spurious or unintentional changing of the combination.

Abstract: The lock button on a door latch is slidable in a horizontal direction between a retracted unlocking position and an extended locking position wherein it blocks a latch hook release member from unlatching the latch, prevents inadvertent locking of the door and extends alongside a strike shoulder on the associated door jamb to provide a secondary latch.

Abstract: A trolley assembly for a pocket door system comprises a central carrier having a plurality of rollers journaled for rotation thereon. A hanger member having a bolt portion which is threadedly received by the carrier includes a laterally extending pintle. The pintle is received within an aperture of a bracket member secured to an upper edge surface of a door. A locking member is insertable into the aperture after the pintle is received therein and includes an abutment portion selectively positionable in proximity to the hanger member. When inserted into the aperture, the locking member blocks relative movement between the bracket member and hanger member thereby preventing removal of the pintle from the bracket aperture. The door height is conveniently adjusted by removal of the locking member and dissociation of the bracket member from the pintle whereupon the hanger member can be selectively threaded inwardly or outwardly of the carrier.

Abstract: A pocket-door assembly includes a pair of trolley assemblies fixed to an upper edge of a vertically disposed door. A header member is positioned generally horizontally over the door and comprises a central plate portion with a pair of integrally formed downwardly extending tracks for receiving rollers of the trolley assemblies. The header member is attachable to a standard dimension lumber member of the wood frame structure within which the pocket-door assembly is intended to be inserted, and is preferably a unitary extruded metal structure. A plurality of vertical stud members are fixed at their upper ends to the header member on opposite sides thereof defining a pocket within which the door is receivable. The stud members each comprise a metal channel member having a generally C-shaped cross section into which a standard dimension lumber piece is inserted.

Abstract: A coil spring has elliptical openings in the end turns for non-rotatably receiving elliptically shaped studs which are press-fitted into the spring, the ends being respectively attached to a pair of mounting brackets.

Abstract: A trolley assembly including a channel shaped body and a pair of frictionless bearing assemblies which include a split tubular spring liner constituting the outer race of the bearing and the wheel axle extends through the space between a plurality of roller bearings positioned between the axle and the outer race. End spacers are secured between the trolley wheels and the body for controlling the end play of the roller bearings and of the trolley wheels.

Abstract: A latch for use with a gate includes a latch body having a planar mounting surface on a rearward side thereof with a pair of space apart flanges which receive a bolt in openings thereto. The bolt is positioned parallel to the surface of the gauge and is slidably and rotatably disposed within the flange openings. An enlargement on one side of the bolt will allow the bolt to pass through one of the flanges when in a predetermined angular position for removal. However an offturned end of the bolt extends rearwardly of the mounting surface, and the bolt enlargement is so oriented such that the bolt is not removable from the latch body when the body is normally attached to the gate.

Abstract: A door frame is fabricated of rolled sheet metal vertical frame pieces each including a first channel for receiving the end portions of wood or metal horizontal crosspieces and a second channel for receiving the end portions of corrugated or other panel members, the latter channel being formed by rolling a portion of the sheet metal back on itself to provide a double walled strength portion.

Abstract: A door closer includes a spring-loaded piston forming part of a conventional pneumatic dashpot, which retards the speed of a door during closing, and an elastomeric sleeve which is longitudinally compressed during opening of the door to retard the speed of the door during opening and to apply substantial resistance to further opening movement as the door approaches its fully open position. Closing speed of the door is also initially retarded by the compressed sleeve.

Abstract: Door speed is controlled by a pneumatic dashpot including a spring-loaded piston having a piston rod which extends through an elastomeric silicone rubber braking sleeve which is longitudinally compressed as the door opens to increase the friction between the piston rod and the sleeve. One or more enlargements on the piston rod provide increased friction as the rod moves through the braking sleeve to control closing speed and to provide greater wind resistance.

Abstract: A jamb latch for a sliding door utilizes a pivotally mounted operating arm which in one position is used to pull the door in tightly against the jamb and to latch the door in place and which in a second position extends across the edge of the door to hold it in an open position.

Abstract: A sliding door is suspended from a top rail for movement across a doorway and is guided at the bottom by a J-shaped rail mounted to the side of the building adjacent the doorway and extending upwardly into a downwardly opening channel provided along the bottom of the door.
