Abstract: A side rail assembly useful for securing a deck of a scaffold comprises a side rail configured to be supported between two ladder frames in first and second orientations. The side rail includes first and second support surfaces for supporting the deck in the first and second orientations, respectively. First and second vertically aligned slots are formed in respective opposing surfaces of the side rail. The side rail assembly further comprises a locking pin assembly comprising a shaft, a locking tab, and a biasing member to bias the locking tab into engagement with the deck and secure the deck against one of the support surfaces of the side rail depending on the orientation. The locking pin assembly is configured to be removably engaged with the first and second slots of the side rail in both the first and second orientations.

Abstract: A coupling pin clip for a coupling piece for the connection of two components that are inserted between them. To affix the insertable coupling at the ends of the coupling piece, a pin is insertable both through a hole of the component and through a hole of the coupling piece. The coupling pin clip is U-shaped, the legs of which have a distance from each other that corresponds to the distance of the two holes in the coupling piece. Furthermore, the coupling pin clip comprises a tipping finger articulated at one end of the coupling pin clip.

Abstract: A cufflink including a head portion with a bearing surface for bearing against a garment, a pin portion to be inserted through a hole or a slot of the garment, and a clasp portion with at least one pivotable tab for locking the cufflink onto the garment. The cufflink includes an actuator with a shaft slidably mounted in a housing and including a push button at one end and an actuation arm at the other end which is inserted into an actuation portion of the tab (so as to pivot the tab from an unlocked position into a locked position when the push button is pressed. The cufflink further includes a locking-unlocking mechanism with push buttons arranged on either side of the shaft of the actuator, wherein the push buttons can be accessed from the opposite sides of the side wall.

Abstract: An item of jewelry such as a cuff link which is provided with a self-locking holder in order to provide absolute security and assurance that the holder will not permit the item of jewelry to come loose and fall. The self-locking holder for an item of jewelry comprising: a U-shaped stem for holding the item of jewelry; a pin extending across the opening between the side members of the stem; a slidably and rotatably locking member mounted on the pin; and a spring for biasing the locking member toward one side member for locking the locking member in place.

Abstract: Mounting means for removably securing a circuit board in a fixed spaced relationship to a base plate. The mounting means includes one or more fasteners, each comprised of a spacer member and a latch member. The spacer member includes a disk-like portion having a first flat surface for securement against the base plate and a second flat surface on which the circuit board is supported. A post extends from the disk-like portion second flat surface through an opening in the circuit board. The latch member is mounted for movement on the post between a first position which allows it to pass through the circuit board opening and a second position in which it is locked against one surface of the circuit board forcing the opposite circuit board surface against the disk-like portion second flat surface.
