Abstract: A locking ring includes an annular split ring portion with a U-shaped cross section and resiliently separable end portions, with each end formed into an L-shaped wall portion terminating in a serration. When the ends of the locking ring are brought together, the serrations intermesh, and the wall portions form a rectangular enclosure. Substantially solid front and rear housings portions, each containing a hole for receiving a barrel lock and an external groove, fit into the enclosure. The rear housing portion is attached to one wall portion, with its external groove fitting over the rear lip of the U-shaped cross section of the enclosure. The front housing portion is attached to the other wall portion, with its groove fitting over the front lip. When the locking ring is closed, the front housing portion slides over the rear housing portion until the lock receiving holes align. The locking ring also includes a replaceable seal retainer.

Abstract: A weatherproof sliding closure such as a window, door or hatch, especially suitable for closing openings in a marine environment, is disclosed. The closure is mounted top and bottom on bearing assemblies via camshafts extending through the closure and rotatably mounted in the assemblies. The bearing assemblies travel along fixed top and bottom guideways to move the closure between open and closed positions with respect to the closure opening. Cam portions of the shafts act against internal portions of the closure itself, serving as cam followers, when the camshafts are rotated in unison in the same direction through operation of a closure handle and drive train interconnecting the camshafts internally of the closure. This causes the closure to shift laterally on its bearing assemblies into sealing engagement with a closure frame defining the closure opening.

Abstract: A flush-closing multi-pane window assembly for a motor vehicle is provided, comprising a frame for mounting in a window recess in the vehicle body, one or more fixed-position panes mounted to the frame and at least one sliding pane mounted to the frame for sliding between an open position and a closed position. In its open position, the sliding pane overlaps a fixed-position pane, but in its closed position is substantially flush therewith. Guide means are provided for guiding the sliding pane as it moves laterally between its open and closed position. The guide means includes fixed members extending from the sliding panes substantially perpendicular to its direction of travel and kick-out means provided by the frame for engaging the fixed members at least during initial lateral movement of the sliding pane from its closed position to its open position.

Abstract: A method of increasing the range of controlled movement of a door opened by a treadle operated door opening assembly is described, along with a treadle operated door opening assembly constructed in accordance with the teachings of the method. The method includes the step of mounting a contact member which projects from the first face of the door adjacent to the hinge edge and the bottom edge. With this modification when a person treads upon a radially extending pedal a shaft rotates causing a point of contact between the arm and the door to move sequentially from a first position substantially parallel to the first face of the door to a second position engaging the contact member substantially perpendicular to the first face of the door.

Abstract: A pressure-fit barrier such as a gate has a first panel member coupled to a partially overlapping second panel member so that the panels are slidable laterally relative to each other, thus changing the overall width of the gate. A carriage member is slidably mounted on the second panel for lateral movement relative to the second panel and a displacing mechanism is coupled with the carriage member and the second panel and is selectively operable to laterally displace the carriage relative to the second panel. An engagement mechanism is connected to the carriage for selectively engaging with and non-engaging with the first panel. When the engaging mechanism is non-engaged lateral movement of the carriage member with respect to the second panel does not cause relative lateral movement between the first panel and the second panel, and when the engaging mechanism is engaged lateral movement of the carriage member causes corresponding relative lateral movement between the first panel and the second panel.

Abstract: A window operator and lock structure for controlling a window sash relative to a window frame, including a drive input securable to a frame and engaging both an operator linkage securable to a window sash to effectuate motion of a secured sash relative to a frame, and a lock linkage securable to a lock structure for locking a secured sash to a frame. A link in the lock linkage moves in a generally longitudinal direction when operating the lock structure and includes a substantially transverse slot. A cam is pivotable about a cam axis fixed relative to the frame and includes a member receivable in the link slot to block operation of the lock linkage. The sash when closed against the frame includes a member engaging the cam to pivot the cam in a first direction moving the cam member clear of the link slot. The cam is blocked from pivoting when the sash is closed by engagement of the cam member with a side surface of the lock linkage link.

Abstract: A high impact resistant rotationally molded door and process for molding the door is disclosed in which a hinge member is integrally molded to the door along one edge only. This hinge member forms to the hollow door edge without door warpage during curing and shrinking of rotationally molded plastic door body. Door warpage is avoided by delaying full integral attachment of the hinge member to the door until curing of the injected foam interior which both bonds to the interior of the door and the hinge member. An improved seal and hinge seal is disclosed together with a placed window construction that can include both placement and shaping to meet the special order needs.

Abstract: A gate has a first panel member coupled to a partially overlapping second panel member so that the panels are slidable laterally relative to each other, thus changing the overall width of the gate. An over-center type toggle linkage has a pivot link and a handle link and is operable to laterally expand and contract the lateral distance between the ends. One end of the pivot link is pivotally connected to the first panel and the other end is connected to a medial portion of the handle link. One end of the handle link is pivotally connected to a sliding carriage that slides relative to the second panel and the carriage and handle link end are selectively engagable with the second panel by a releasable engagement mechanism. When the engagement mechanism is disengaged, the panels are free to slide laterally to change the width of the gate. When the engagement mechanism is engaged, operation of the toggle linkage expands or contracts the overall width of the gate.

Abstract: An automotive vehicle door 10 having a window panel 22 movable to close and partially open a window opening 18 is stabilized against lateral movement when in a partially open position by a lower channel 28, mounted substantially below a beltline section 32 of the window opening 18, which has a narrowed width section 64 with sides 46 inwardly crimped along a longitudinal axis thereof for cooperating with a deformable glass run 66 mounted within the lower channel 28 to restrict inboard and outboard movement of the window panel 22. A sleeve 52 between the lower channel 28 and a middle channel 26 limits relative lateral movement therebetween, and a reinforced window seal 36 along the beltline section 32 of the door 10 provides further lateral support for the window panel 22 in the partially opened position.

Abstract: An automatically-actuated sealing device is disclosed which seals a gap between a door bottom (or edge) and a surface defining part of an opening through which weather, dust, insects, etc. may otherwise pass. The sealing device includes a support element attachable to the door bottom, a seal actuating element movably supported by the support element, a sealing element moved by the seal actuating element into a sealing position, and a plurality of metal, plastic or metal and plastic spring elements which couple the seal actuating element to the support element and urge the seal actuating element to seal the gap. The sealing devices operate by coupling the device to the opening defining surface so that opening and closing of the door generates movement of the seal actuating element. A projection on the seal actuating element is engaged by the door jamb or a bearing element attached to the jamb, and is laterally moved in response to opening and closing the door.
