Abstract: A support mechanism for a part of a circuit card includes a support member (slide) which forms a fixed part. The support member defines a guide. It also includes a slideable member for engaging the circuit card. The slideable member (slider) is slideable along the guide to a position for engaging the card. The slider defines a jaw for engaging the circuit card. The jaw can be provided with a protrusion for engaging with a hole in the corner of a circuit card, for example a PCI card. The mechanism enables the supporting of cards of different lengths due to the slideability of the slide along the guide. The guide and the slider can be formed with inter-engaging structures of appropriate shapes, for example, co-operating dovetail shapes.

Abstract: A mounting bracket forms a rack mount for a rack-mountable unit. The mounting bracket includes a planar body portion and a latching pivot for insertion into an aperture in a side wall of the rack-mountable unit. A head on the latching pivot is arranged to be insertable into a correspondingly shaped aperture, with securing of the mounting bracket to the rack-mountable unit being achieved by rotating the rack mount with respect to the rack-mountable unit with the latching pivot fully inserted into the aperture. On rotation, the head of the latching pivot is arranged to engage behind the side wall of the rack-mountable unit to secure the mounting bracket to the rack-mountable unit. Detent flanges on the mounting bracket prevent over-rotation of the bracket. A flange is provided for attaching the mounting bracket to the rack.
