A movable support structure is provided with a first component including a movable supporting portion and a retaining/restricting portion, and a second component including a supported portion and a receiving portion. The movable supporting portion restricts a movement toward a back side in a sliding direction of the supported portion slid toward the movable supporting portion along a first direction. The slid supported portion is supported movably along the first direction and a second direction orthogonal to the first direction. The retaining/restricting portion extends in such a posture as to gradually approach the receiving portion from a position separated from the receiving portion on a side opposite to the second component toward a sliding side of the supported portion.

The present disclosure provides descriptions of configurations for bonding washers used to facilitate the electrical bonding of metal structures. The bonding washer includes an electrically conductive body and at least one piercing member extending from a bottom surface of the body. An extended member extends from the electrically conductive body in a direction away from the bottom surface of the body.

A retention device for supporting a component relative to a wall of a home appliance is provided. The retention device includes a backing nut and a core piece that can be installed from a single side of the wall. The backing nut defines a central bore and includes a threaded surface. The core piece includes a body having a threaded portion configured to mate with the threaded surface of the backing nut and at least one flange projecting outwardly from a body of the core piece. The core piece is configured to be inserted into an aperture in the wall and rotated to engage the at least one flange with the wall.

A connector includes a body having gear teeth. A first sleeve is rotatably coupled to the body. A moveable member is positioned in a hole of the first sleeve. A second sleeve is movable with respect to the first sleeve between a locked and unlocked positions. A releasable locking member is positioned between the moveable member and the gear teeth. In the unlocked position of the second sleeve, a recess formed in the second sleeve is aligned with the opening. Upon rotation of the first sleeve, the moveable member is translated into the recess as the releasable locking member travels along the gear teeth. In the locked position of the second sleeve, the recess is rotationally spaced from the opening, and, the releasable locking member is sandwiched between the gear teeth and the moveable member to prevent rotation of the first sleeve with respect to the connector body.

A bistable device including a fixed baseplate, at least two levers, a tappet rigidly secured to between each lever and the baseplate and aligned in a first direction, where a lever is capable of displacement relative to the baseplate so as to displace the associated tappet substantially in translation in the first direction, and a member that is able to take two positions, the device additionally including a rocker associated with each lever, arranged between the baseplate and the associated tappet, including two V-shapes facing the associated tappet, where the associated tappet in the first V-shape tends to turn the associated rocker in a first direction and the associated tappet in the second V-shape tends to turn the associated rocker in a second direction opposite to the first direction, the rockers being synchronized in rotation and the rockers being synchronized with the member.

A connection arrangement for tubular members may include a latch arrangement having a latch hook attached to a first tubular member and a striker arrangement attached to a second tubular member. The striker arrangement may include a transverse member extending transverse to the length of the second tubular member. The transverse member may be positioned proximate to the latch hook when an end of the first tubular member is positioned adjacent to an end of the second tubular member such that rotation of the latch hook engages the transverse member and effects a clamping force between the first tubular member and the second tubular member in a direction transverse to the rotational axis of the latch hook.

A fastening structure includes a fastening member including a bolt and a plurality of fastened members that are fastened and fixed to the fastening member. Further, the bolt contains pure aluminum or an aluminum alloy. At least one fastened member of the plurality of fastened members contains pure aluminum or an aluminum alloy. Pure aluminum or an aluminum alloy of a screw portion of the bolt is brought into direct contact with pure aluminum or an aluminum alloy of at least one fastened member.

Conductively coated fastening systems are disclosed herein. An apparatus includes a fastening system and a structural assembly. The structural assembly comprises a first structural element made of an electrically conductive fiber reinforced plastic and a second structural element. The first structural element comprises a first hole and the second structural element comprises a second hole. The first and second holes are separately pre-formed prior to assembly of the structural assembly. The structural assembly further comprises an electrically conductive gap filler applied to a first structural element sidewall of the first hole of the first structural element. The fastening system comprises a fastener comprising a head and a shank extending from the head. The shank is configured to be inserted into the first hole and the second hole.

Method of manufacturing a ground apparatus and ground apparatus comprising an aluminum nut (16) having an internal thread and adapted to clamp an eyelet (28) of an electrical conductor on a corresponding contact area of the stud (12), wherein the nut (16) has at least one coating (30) which contains at least zinc, characterized in that the coating further comprises tin, in that the coating consists of an acid tin-zinc electroplating on the aluminum nut (16) and is such that the tin is between 60 and 80% by weight of the coating and the tin-zinc coating forms a layer with an average thickness of from about 5 to 16 microns

Provided is an invention relating to a bolt having a crushed portion of a ridge formed on a regular threaded portion of the bolt. The crushed portion of the ridge is set to have a height at which no screwing torque is generated when the bolt is screwed into an internal thread, and the crushed portion of the ridge is formed on an entire half-circumference or a partial half-circumference of the regular threaded portion so as to form a spiral shape that advances toward a shaft tip in a direction opposite to the ridge of the regular threaded portion when viewed from a head. The bolt of the present invention is used as a locking bolt or an earth bolt.
