A seal cover for closing an annular opening portion having locking projections provided on an outer peripheral surface includes a fitting portion having a seal ring (example of a sealing member) fit on an outer peripheral surface and locking portions configured to be pushed and resiliently deformed by the locking projections and move over the locking projections to be locked to the locking projections when the fitting portion is fit into the opening portion. Tapered surfaces for delaying a time point when the locking portions are maximally resiliently deformed from a time point when the seal ring is maximally compressed when the fitting portion is fit and inserted into the opening portion are formed on front end parts of the locking portions in a connecting direction.

A spacer assembly for spaceably coupling a first and second component with a threaded connection bolt, each one of the first and second component provided with one or more fitting apertures. The spacer assembly includes a support member, a base member, and a spacer member having resilient friction elements configured to provide an interference fit engagement with a predetermined friction force with a threaded connection bolt, during use.

A mounting device includes a panel portion, and a fastener receiving structure provided within a perimeter of the panel portion. The fastener receiving structure can include a flexure mechanism to enable at least a portion of the fastener receiving structure to flex with insertion of a fastener into the flexure mechanism that attaches the panel portion against an underlying surface.

The present invention provides a fastener alignment guide comprising a generally planar body and an angled element arranged at an acute angle θ to the body, a first aperture arranged through the angled element and a second aperture arranged through the body, wherein the first aperture and the second apertures are aligned such that a fastener may be inserted progressively through the first and second apertures in use. The present invention also provides a slip-resisting fastener alignment guide comprising a body at least partially arranged in a first plane, the body comprising a first aperture for receiving, in use, at least a portion of a shank of a fastener; and a guidewall extending out of the first plane for guiding the fastener, in use, into the first aperture at an acute angle α to the first plane, wherein the guidewall comprises a first bearing edge or surface upon which an underside of a head of the fastener can bear in use, the body further comprises a second bearing edge or surface upon which the underside of the head of the fastener can bear in use, and the first bearing edge or surface and the second bearing edge or surface are each configured/arranged to resist movement, in use, of the fastener alignment guide relative to the fastener in a first direction parallel to the first plane.

The present invention also provides a method of forming the fastener alignment guide and slip-resisting fastener alignment guide.

A transmission wheel assembled of at least two segments (1) on a shaft (12), the inner arc surface (3) of which and the shaft (12) have essentially the same radius (R), and which segments' (1) outer surfaces (9) have profiled surfaces that transmit the power of the transmission wheel. Between the segments' (1) welded-together end faces (4) there are gaps on those sections of the end faces (4) that are not welded, which creates a press fit between the shaft (12) and the inner arc surface (3) of the transmission wheel. The weld connecting the transmission wheel segments' (1) end faces (4) may be incomplete, meaning that it does not reach the shaft (12).

A mounting bracket assembly for securement of elongate items, such as wires, cables, or other bundles items to a support structure. The mounting bracket assembly may include a clamp member defining a first clamp member and a second clamp member joined to the first clamp member by a hinge mechanism. The mounting bracket assembly may also include a locking mechanism, a wedge-shaped pawl having a plurality of teeth disposed within the slotted opening, and a mounting member defining a mounting aperture configured to receive an attachment feature therethrough.

An assembly-ready joint for an aircraft assembly is disclosed. The joint includes a first joint part having a spigot. The joint also has a second joint part with a housing. A floating socket is in an interior of the housing. The second joint part receives the spigot in the floating socket. The joint is arranged to receive a curable medium, such as curable resin, in the interior to contract between the housing and the floating socket.

A mounting assembly for use in mid-grab and/or edge-grab applications may include a clamp secured to a stanchion by a clamping fastener. The mounting assembly may also include a mounting plate which may be secured to a mounting device by the stanchion. The mounting assembly may be used, for example, to secure photovoltaic modules (or other devices or structures) of varying heights to a roof or other building surface.

A system and method including a fastener clip including a top portion and a bottom portion. The bottom portion includes a platform, a pair of locking arms and a pair of feet. The pair of locking arms is coupled to the platform via a pair of hinges. The pair of feet is coupled to the locking arms and is being configured to rotate with the locking arms. The feet are configured to be partially inserted into a slot in a doghouse and, based at least on the locking arms being rotated, the feet are configured to rotate into the slot in the doghouse and to couple the bottom portion to the doghouse. The locking arms are configured to be coupled to the platform at the end of the rotation.
