  • Patent number: 10709035
    Abstract: A rail clamp latch holder is provided. The rail clamp latch holder includes a grippable portion and a rail portion disposed at a forward side of the grippable portion. The rail portion includes first and second pairs of opposed latches which are configured to latch onto a rail and which are disposed at first and second longitudinal ends of the rail portion, respectively, a tab, a locking pin and an elastic member. The tab is insertable into a rail latch. The elastic member extends along a longitudinal axis of the rail portion and elastically couples the locking pin and the tab.

  • Patent number: 10314219
    Abstract: A device comprises a rail configured to span and detachably couple to a housing. The device includes a plate that engages the housing and a mechanism securing the tool to the housing. The housing contains a printed circuit board configured with at least one row of slots, each slot configured with a retainer mechanism. A jaw assembly slides along the rail over more than one card positioned in the row of slots. The assembly includes a pair of inserts that perform either seating or extracting more than one card positioned in more than one slot. The device includes a lever for biasing the jaw assembly, where the inserts engage a selected one of more than one card positioned in more than one slot and the retainer mechanism for performing either simultaneously seating more than one card into or simultaneously extracting more than one card from more than slot.
