摘要:
Block seals of pile weatherstripping (6), which may be inserted in doorjambs or window sash and are sometimes called dust plugs (15), are provided by hinged segments (16-21) of a continuous length of pile weatherstripping folded against each other. The pile may have an infiltration barrier providing a fin (4) which extends along a continuous serpentine path having loops (8) bridging the hinges (3). The hinged sections are connected by an adhesive-backed sheet (5). The block seals are adapted to be manufactured by a continuous process where the backing or base strip (7) of a continuous length of pile weatherstripping (1) is slit or notched from opposite spaced edges, leaving sufficient material in the backing to provide the hinges (3). The continuous serpentine barrier fin (4) allows the dust plug (15) to be installed oriented either with the ends or sides of the pile facing the moving member of the door or window to be sealed, while maintaining the fin infiltration barrier.

Dust plugs provide seals for openings in door frames and window frames to seal against air or water infiltration. The dust plugs are made continuously and automatically by feeding several weatherstrips having piles extending from rigid backing through a tool having side by side slots there through which extend from an anvil surface thereof. The backing strips rest on the surface in edge-to-edge relationship. An adhesive tape having a contact adhesive on one side thereof is fed synchronously with the pile weatherstripping in juxtaposition with the weatherstrips and in contact with the exposed sides of the backing strips. The dust plug material consists of the tape in contact with the weatherstrips and provides an assembly of the weatherstrips and the tape. Counter rotating puller belts engage dust plug material which may then be wound on a reel. For installation of the dust plug, the dust plug material is unwound from the reel and cut into dust plugs of desired length. Guides on upstream and downstream ends of the tool bring the tape into contacting relationship with the weatherstrips to provide the assembled dust plug material.

A cushioning member is located between each support frame and the corresponding side of the shutter. The cushioning member includes a pair of belt-shaped base members and pile yarns bridging between the base members. Some of the pile yarns are cut at intermediate portion between the base members, which forms opposing first and second cut pile yarns with a cut in between. One of the base members is attached to each support frame, and the other base member contacts the shutter. The cut permits the cushioning member to flexibly respond to movements of the shutter and satisfactorily exerts a cushioning function to suppress swaying of the shutter.

An adjustment mechanism for use in a mounting system comprising a first mounting portion configured to operatively connect to the audio/visual device and a second mounting portion configured to attach to the first mounting portion and to a mounting surface. The adjustment mechanism operatively connects the first mounting portion to the second mounting portion. The adjustment mechanism includes a housing with a bore formed therein, a clutch positioned within the housing, and a rotatable shaft positioned within the housing and being operatively connected to the first mounting portion. The shaft is configured to rotate within the bore relative to the housing. The shaft is rotatable within the bore in a first rotational direction through the clutch with a first torque, and the shaft is also rotatable within the bore in a second rotational direction through the clutch with a second torque.

A pile article is provided having a band of textile material, and a plurality of fiber loops defining a pile having sides from ends extending longitudinally along the band. The band is ultrasonically welded to the ends and a portion of the sides of the pile, and is sufficiently wide to support the sides of the pile substantially upright. An interior textile strip may optionally extend longitudinally within the pile at the ends of the pile and within a portion of the pile sides.

Weatherseals are provided by a pair of base members (21c, 21d) which may be attached to a pile (22) formed by winding fibers (yam) around a band (51) as the band travels along an endless path. A section of the pile (22) on one side of the endless band (51) is cut to provide cut pile section (23) and a continuous pile section (22a). The continuous pile section (22a) forms the bow, arch or loop (22e) by disposing the base members (21c, 21d) in side-by-side, back-to-back, or perpendicular relationship. The cut pile section (23) may be removed at the base members (21c, 21d) or halves of the cut pile section (22b, 22c) maybe left in place. The remaining cut pile section halves (22b, 22c) form one or more brushes along the outside or inside of the bow, arch, or loop (22e) formed by the continuous pile section (22a). The outside surface (22d) of the bow, arch, or loop (22e) may be provided by a sheet or fin (80) of thin material which controls the imperviousness to moisture or air infiltration and the frictional characteristics of the outside surface. The fin material (110a, 110b) may also be disposed on the outside of the brushes formed by the cut pile section halves (22b, 22c). The fin material (80) may be applied on the endless band (51), or fin material (110) may be applied over the pile (22) wound thereon, and attached together with the pile (22) to the base members (21c, 21d). The cut pile section halves (22b, 22c) and the outside surface (22d) of the bow, arch, or loop (22e) may be attached by base members (21c, 21d) to a member, such as by adhesive or via one or more T-shaped slots, that is in sealing relationship with another member and engagable therewith to provide a resilient seal.
