Abstract
A wedge bar locking mechanism is provided including a locking pin, a bracket and a wedge bar. In operation, the locking pin and wedge bar are mechanically coupled such that rotation of the locking pin results in translational motion of the wedge bar. The wedge bar and locking pin are received in the bracket which prevents rotational motion of the wedge bar and translational motion of the locking pin. In a preferred embodiment, the bracket has retaining tabs permanently attached or integral thereto, and extending radially inward of a longitudinal cylindrical pathway for accommodating the locking pin therein. The tabs are received within a reduced diameter portion of the locking pin to prevent translation thereof.
Claims18
A wedge bar locking mechanism comprising a locking pin, a wedge bar and a bracket,
- said locking pin comprising a reduced diameter portion and a threaded portion, said threaded portion having a continuous helical groove disposed circumferentially about and extending longitudinally of said threaded portion,
- said wedge bar comprising first and second longitudinally extending portions at a proximal end thereof, said first and second longitudinally extending portions defining a locking pin receiving space therebetween, at least one of said first and second longitudinally extending portions having at least one tooth extending into said pin receiving space, said tooth being dimensioned to extend into and be accommodated within said helical groove when said threaded portion is received in said pin receiving space,
- said bracket defining a longitudinally extending slot adapted to accommodate said wedge bar therein, and a longitudinally extending cylindrical portion defining a longitudinal cylindrical pathway adapted to accommodate said locking pin therein,
- wherein said slot is effective to prevent said wedge bar from rotating as a result of torque supplied to said locking pin when said locking pin and said wedge bar are received, respectively, in said longitudinal cylindrical pathway and said slot.
A wedge bar locking mechanism comprising a locking pin, a wedge bar and a bracket,
- said locking pin comprising a reduced diameter portion and a threaded portion, said threaded portion having a continuous helical groove disposed circumferentially about and extending longitudinally of said threaded portion,
- said wedge bar comprising a longitudinally extending portion at a proximal end thereof, said longitudinally extending portion having at least one tooth dimensioned to extend into and be accommodated within said helical groove disposed in said threaded portion of said locking pin,
- said bracket defining a longitudinally extending slot adapted to accommodate said wedge bar therein, and a longitudinally extending cylindrical portion defining a longitudinal cylindrical pathway adapted to accommodate said locking pin therein.
