Title: Lever action floor latch actuation mechanism with cinching mechanism
Inventor: NICOLA KIRK M
IPC: E05C9/18
Filed: 1999-05-13
Granted: 2007-09-25
Abstract: A lever action floor latch actuation mechanism for removably securing a seat to a pair of front and rear strikers on the floor of a vehicle. A riser having a forward leg and a rearward leg supports the seat above the vehicle floor. Front and rear latches are pivotally connected to the forward and rearward legs, respectively, for releasably securing the seat to the strikers. A longitudinal links pivotally interconnects the front and rear latches and an actuation member coupled to the link simultaneously moves the latches between a latched position engaging the strikers and an unlatched position disengaging the strikers. Each latch includes a cinch cam pivotally connecting the latch to the riser. The cinch cam has a cylindrical outer surface terminating at a flattened cam surface. A spacer plate is fixedly secured between the latch and the riser and includes a center aperture for rotatably receiving the cinch cam. The aperture forms a circular section and a tangential slot for seating a flexible plate. The cylindrical surface of the cam engages and flexes the plate when the latch is pivoted to the latched position providing an anti-rattle biasing force between the latch and striker and the flattened surface release the flex in the plate when the latch is pivoted to the unlatched position disengaged from the striker.

Abstract: In a partially grouted concrete masonry wall, the bed joint reinforcement is provided by a set of rings spaced along the mortar between two adjacent courses of blocks and wire strands on opposite sides of the rings. Each of the grouted cells of the wall is surrounded by reinforcing rings embedded in the mortar. The rings support the columns of grouting in the wall and more effectively transfer loads to the bed joint reinforcement than does conventional truss or ladder style bed joint reinforcement. Between courses where bed joint reinforcement is not used, independent rings may be employed to support the grouting columns.
