Described herein is a ceiling system in one embodiment includes a grid support member, ceiling panel, and grid hanger configured to support the grid support member in a suspended manner from an overhead structural support. The grid hanger includes a mounting bracket configured for attachment to the structural support and a hanger member. The hanger member is adjustable in a plurality of selectable mounting positions relative to the mounting bracket, thereby allowing the mounted height of the grid support member to be adjusted in the field. In some embodiment, the hanger member is further angularly adjustable relative to the mounting bracket to avoid installation obstacles. Locking elements are provided to secure the hanger member in the selected mounting position. In one embodiment, the grid support member may have a T-shaped cross section.

The vertical leg is integral with the catch-side wing and has a top end and a bottom end. A plurality of inwardly facing corrugations are disposed at the bottom end of the vertical leg. The solar panel mounting assembly further includes a base that includes a secure-side support surface, a tilted spring support ledge on a catch-side, and a plurality of outwardly-facing corrugations disposed on an upper horizontal portion of the base. An inwardly-facing corrugation of the vertical leg contacts and engages an outwardly-facing corrugation on the upper horizontal portion of the base, and the base is vertically adjustable with respect to the cap.

A system including means for reducing or prohibiting a loosening of a threaded fastener, in which the threaded fastener comprises at least one or more nuts and a threaded bolt.

A female connection bracket includes a catch in the first end portion of the body. A male bracket includes a first end portion of the male bracket, and, the first end portion includes a pivot opening and a latching opening. A clip includes a latch portion and a gripping portion, the gripping portion includes a barb residing in the pivot opening of the male bracket rotatably affixing the clip to the male bracket. The latch portion of the clip releasably resides in the latch opening of the male bracket. The male bracket resides in an open channel formed by first and second guides of the female connection bracket. The latch of the clip releasably interengages the catch in the body of the female connection bracket, alternately, retaining and securing, or, releasing, the male bracket with respect to the female connection bracket.

A pedal assembly comprises a pedal arm; a pedal plate provided on a second end of an elongated lever structure of the pedal arm; a vehicle mounting bracket; and a retainer. The retainer is installed on the pedal arm and is configured to operatively connect the pedal arm and an end portion of an operating member so as to transmit the movement of the pedal arm between a first and a second arm position to a functional system. The retainer is in an open position for insertion of the end portion of the operating member therein. The retainer is configured to move or to be movable from the open position to a closed position in which the retainer retains the end portion of the operating member received therein. The retainer is movable from the open position to the closed position by insertion of the operating member therein.

A splice having a main body and one or more protrusions extending from the main body. The one or more protrusions can be operable to interfere with a rail when the main body is installed into an opening of the rail. The one or more protrusions may be operable to cut into a coating of the rail and form an electrical connection between the rail and the main body.

A conceal buckle apparatus includes a box, a buckle, an axle and a locking element. The box includes a rim, a back plate and a connective plate formed between the rim and the back plate. An opening includes a portion in the connective plate and another portion in the back plate. The buckle includes two lateral portions extending out of the recess via the opening and a middle portion extending perpendicular to the lateral portions. The axle is connected to the lateral portions of the buckle and formed with two terminal sections each of which comprises at least three faces. The locking element is connected to the box and formed with five contact portions. Two of the contact portions are in contact with two of the faces of the axle when the lateral portions of the buckle extend perpendicular or parallel to the back plate.

A tolerance ring having a first axial end, a second axial end, and a central axis, the tolerance ring including an annular band; a plurality of protrusions, all of the plurality of protrusions extending from the annular band; and a guide portion extending from the annular band towards the first axial end of the tolerance ring, where the guide portion includes a guide surface that is curved in an axial section.

A window clamp system and method are to secure a window pane to a window frame of a vehicle. The window clamp system includes a mounting bracket configured to be secured to the window frame, one or more ratchets coupled to the mounting bracket, and a spring clip configured to move in relation to the mounting bracket and the one or more ratchets. The spring clip is configured to engage a seal positioned around the window pane.

A tolerance ring has a hollow band with outwardly extending corrugated protrusions forming waves that engage an inner surface of a bore of a housing. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to assist the insertion of a shaft into the hollow band during assembly of the ring into the bore of the housing.
