Abstract:
1. An assembly comprising: an elongated rigid cane bolt engageable with a movable barrier to selectively hold the movable barrier stationary with respect to a fixed barrier, the cane bolt defining a long axis and a pin extending away from the long axis, the cane bolt defining a top end and a bottom end, the pin being disposed on the cane bolt distanced from the bottom end intermediate the top end and bottom end; a spring coupled to the cane bolt to bias the cane bolt to a raised position in which a bottom end of the cane bolt is above the ground; a stop engageable with the movable barrier and defining a central opening through which the cane bolt moves but through which the pin cannot move, the stop also defining at least one slot through which the pin can move when aligned with the slot, wherein the cane bolt is manually movable against the spring to a lowered position, in which the bottom end of the cane bolt is received in a strike hole in the ground below the movable barrier, the cane bolt being rotatable to assume an angular orientation about the long axis in which the pin is below the stop and is not aligned with the slot to thereby cause the pin to abut a bottom surface of the stop under the influence of the spring while preventing the spring from raising the cane bolt from the lowered position, the cane bolt being rotatable to assume an angular orientation about the long axis in which the pin is aligned with the slot to thereby permit the pin to pass through the slot to in turn permit moving the cane bolt between the raised and lowered positions; a spring support engageable with the movable barrier below the stop; and a spring trap coupled to the cane bolt above the spring support and below the stop, the spring being disposed in compression between the spring support and the spring trap when the assembly is engaged with the movable barrier; the stop being engageable with the movable barrier at an upper location above the spring trap relative to the bottom end of the cane bolt when the cane bolt is in the lowered position in which the spring is compressed between the spring trap and the spring support, the spring trap contacting the stop when the cane bolt is in the raised position in which the spring is expanded relative to the lowered position such that the spring expands and contracts between the stop and the spring trap, the stop being engaged at the upper location by welding or by a bracket, the pin being longitudinally distanced on the cane bolt from the spring trap.
