A fastening rail for embedding into a concrete element has one rail back, two rail lips and two rail longitudinal sides disposed opposite one another. The rail lips delimit a slot between them. The fastening rail is realized in an anchorless manner and forms at least one undercut from the rail back in the direction of the outside of the rail lips. To improve anchoring in the concrete, the rail back has profiling on its outside which is remote from the rail lips. The fastening rail is advantageously embedded into a concrete element such that the outside of the rail lips lies flush with the surface of the concrete element. A method for making a fastening rail provides that a profiling is produced in at least top one center region a metal plate and the metal plate is re-shaped to form the rail back, rail longitudinal sides and rail lips.

A vehicle seat includes: a first member; a second member; an insertion fastening structure configured to apply an axial tension to an opposed surface portion of the first member and an opposed surface portions of the second member so as to be pressed against each other; and an adjustment member. The opposed surface portion of the second member includes different surface shape portions facing respective surfaces toward directions different from an application direction of the axial tension, and the adjustment member plastically deforms the opposed surface portion of the second member such that the opposed surface portion of the second member, including the different surface shape portions, is pressed and sandwiched between the adjustment member and the opposed surface portion of the first member by the application of the axial tension.

A fitting for channel framing includes a first clip arm configured to extend into a first external fitting groove of the channel framing and clip onto the channel framing, and a second clip arm configured to extend into a second external fitting groove of the channel framing and clip onto the channel framing. An outer portion connected to and extending between the first and second clip arms is configured to span across the continuous slot when the first and second clip arms extend into the respective first and second external fitting grooves and are clipped onto the channel framing.

A fitting for hanging a piece of channel framing includes a coupling component having opposite longitudinal ends, a length extending between the opposite longitudinal ends, a coupling longitudinal portion configured to be secured in the external fitting groove of the channel framing body, and an exposed longitudinal portion configured to extend outward from one of the open groove ends of an external fitting groove for connection to a rod to hang the piece of channel framing from an elevated structure when the coupling longitudinal portion of the coupling component is received in the external fitting groove.

A fastening device includes an insert and an extension bar, where the insert is configured to have a coupling engagement with a bolt so that when coupled together they form a fastener. The insert may include a bolt aperture and an extension aperture. An extension bar may be inserted within the extension aperture to assist with placing and holding the insert into position while the bolt is inserted into the bolt aperture. The bolt and insert may be used to generate a mating engagement between two ancillary structures and fasten them together. While connected to the insert, the extension may be used to assist with maneuvering, positioning, stabilizing and angling the insert to facilitate alignment between the bolt and the bolt aperture. The extension bar may be removed from the extension aperture after the mating engagement is formed.

A device for attaching an object on a rail of a support is provided. The device includes a base designed to bear on the rail, and a device for tightening the base on the rail. The tightening device includes a threaded rod and a nut. A first end of the tightening device includes a tightening heel designed to be placed below the rail to tighten the rail between the heel and the base. A second end of the tightening device includes an element for maneuvering by an operator to tighten/loosen the device. The device can further include a detachable non-return device to prevent any involuntary loosening of the device.

A threaded rod hanger has quick lock plunger mechanism that includes plunger pieces within a tapered hole in a housing. The plunger pieces have tapered outer surfaces. A spring within the housing presses the plunger pieces toward the narrow end of the bore, with the spring located between the plunger pieces and a back plate that closes off part of a wide end of the tapered bore. The plunger pieces have internally threaded surfaces that engage threads on a threaded rod that is inserted into the bore, between the plunger pieces. Once the threaded rod has been inserted between the plunger pieces and released, the plunger pieces are pushed toward the narrow bore end. This causes the plunger pieces to press inward, automatically causing the internal plunger half threads to engage the external threads on the threaded rod.

An aircraft comprises a plurality of spanner bars. Each spanner bar has a pattern of mounting holes separated by lands. A plurality of nut plates engage the spanner bars. Each nut plate includes a body having a mounting surface against one of the spanner bars; and first and second posts extending from the mounting surface and through respective holes in the corresponding spanner bar. Each post has an undercut portion that abuts against one of the lands. Each nut plate further includes a locking member occupying a space between one of the posts and the lands to prevent the nut plate from disengaging the corresponding spanner bar.

The invention relates to an engagement member that is adapted to be fixed in a groove of a component and to a method for interconnecting two components via an engagement member. In order to provide an engagement member and a method, which provide for an easy assembly of the engagement member in the groove, while still providing sufficient forces for interconnecting the two components, the invention provides that the engagement member comprises a fastening pin that can be pushed into a cavity of one of the two components.

A fastener nut for securing a part to channel framing defining at least one internal, generally T-shaped track extending lengthwise of the channel framing. The fastener nut includes a nut body, and first and second wings extending longitudinally outward from respective first and second longitudinal ends of the body. The first and second wings having respective terminal ends defining an effective wing span therebetween that is greater than the length of the body such that at least a portion of the fastener nut has a generally T-shaped side profile. The fastener nut is insertable in the generally T-shaped track of the channel framing to allow the fastener nut to slide along the length of the channel framing and to restrict transverse movement of the fastener nut in the interior, relative to length of the framing, for use in positioning the fastener nut along the channel framing.
