A bracket (1) for mounting an object to a profiled beam (10), which includes a clamp (2) and a support (3) for adjustably securing the object relative to the profiled beam (10). The clamp (2) includes a pair of opposed clamp members (20, 21), a sprung hinge (4) connecting the clamp members (20, 21) together on a first of their sides and a fastener (5) for fastening the clamp members (20, 21) together on a second of their sides. Each clamp member (20, 21) describes a beam receiving recess (22) and includes a retaining lip (25) on the first side for engaging a profiled beam (10). The fastener (5) is operable to fasten the clamp members (20, 21) on the second side of the beam (10), while the retaining lips (25) engage the first side of the beam (10).

An attachment assembly for use with furniture and other articles. The attachment assembly includes a connector assembly that is configured to engage with a rail. The connector assembly includes a first, fixed protrusion, a lever, a second protrusion extending from the lever, and a third protrusion positioned between the first protrusion and the second protrusion. The rail includes a lip and a cutout in the lip that is sized to receive the third protrusion. The rail is configured to retain the connector assembly. Pivoting the lever when the connector assembly is positioned within the rail is configured to cause the second protrusion to bear against a bottom surface of the rail, such that the first protrusion and the second protrusion frictionally engage the bottom surface of the rail and the third protrusion frictionally engages the lip to fixedly hold the connector assembly.

A seat configured for removably securing to a track includes a quick-release fitting for operation by hand to releasably secure a bottom end of a seat leg to a floor-mounted track for facile adjustment and removal of the seat. A threaded stud includes a shaft portion arranged through an opening in an end of the seat leg and a radially extending base. A pivot mechanism has a through-hole arranged around the shaft portion of the threaded stud. A first transverse member and a second transverse member each extend transversely from the pivot mechanism in opposite directions along a pivot axis. A lever is configured to pivot about the pivot axis causing the threaded stud to move up or down via the pivot mechanism, which raises and lowers the radially extending base for alternately securing the seat leg to the track and releasing the seat leg from the track.

A rotary dryer can include a screen that is divided into different portions joined together to form the screen structure. The screen portions can be joined together using one or more quick release latches. Each latch can provide a locking connection between the different screen portions. The latch can be unlocked, e.g., using hand pressure, to disconnect one screen portion from an adjacent screen portion. This can allow quick replacement of one or both screen portions with replacement screen portion(s). The latch may include a latch body and a latch rod. The latch rod may be rotatably connected to the latch body. The latch rod can be connected to one screen portion and the latch body connected to another screen portion. The latch body can rotate around the rotatable connection, causing the screen portions to be pulled together for subsequent use of the screen structure.

An attachment mechanism including a first clamp member having a V-shaped first clamping end and a second clamp member having a V-shaped second clamping end and an adjustment mechanism configured to adjust a relative position of the first clamp member and the second clamp member. The first and second clamp members are configured to translate toward and away from each other via force exerted by the adjustment mechanism such that the first and second clamping ends translate between an engaged and a disengaged position.

A device holder includes a body portion, the body portion having a surface, a first gripping plate and a second gripping plate, each of the first and second gripping plates including a holding surface approximately perpendicular to the surface, a first lever and a second lever, each first and second lever coupled to the body portion at a pivot point via a spring and rotationally movable at the pivot points, and further includes a first sliding bracket coupled to the first gripping plate and a second sliding bracket coupled to the second gripping plate. The first lever is coupled to the first sliding bracket via a first aperture above the pivot point and a second aperture below the pivot point. The second lever is coupled to the second sliding bracket via a third aperture above the pivot point and a fourth aperture below the pivot point.

A clamping device for securely engaging one or more objects through an application of pressure. The clamping device includes a primary member having opposed interior and exterior surfaces. The primary member has a generally cylindrical shape such that the interior surface defines a generally circular space about a center point of the primary member. The clamping device can receive an elongated member through the generally circular space circumscribed by the primary member. The primary member is adapted for clamping and releasing such that the clamping device may releasably engage the elongated member. The elongated member is securely retained by the clamping device through the application of pressure.

A directional lock or a headgear or interface assembly has one or more directional locks that include a catch arrangement for initiating or assisting in movement of a lock member of the direction lock. In some configurations, the catch arrangement assists movement of the lock member in only a portion of a range of travel of the lock member. In some configurations, the directional lock has a housing and a sleeve and the catch arrangement has a catch arm carried by the sleeve. The catch arm includes a catch end that contacts the lock member, which can be a lock washer in some configurations.
