Abstract
An adjustable length astragal having a housing with an upper shoot bolt and a lower shoot bolt positioned adjacent opposite ends of the housing. An actuator is attached to the housing, connected to and configured to simultaneously extend or retract the upper and lower shoot bolts. An adjustable connection assembly is provided between the actuator and at least one of the shoot bolts. The connection assembly adjusts the distance between the actuator and the respective shoot bolt in each of the shoot bolt's extended and retracted positions.
Claims21
At least two links capable of interlocking with one another for removable use in an adjustable length astragal, each of the at least two links comprising:
- a body having a front side, a back side, a first end surface, a second end surface, and a rotational axis passing through each of the end surfaces;
- a pair of tabs extending from the first end surface, offset from the rotational axis;
- a front clamping pocket formed on the front side;
- a back clamping pocket formed on the back side;
- a wing extending from the body on each side of the rotational axis, the wings extending perpendicular to the rotational axis;
- wherein at least one of the wings connects at least one of the at least two links to a slide bar within an astragal;
- and
- wherein rotation of the body of a first link of the at least two links, about the rotational axis, relative to the body of a second link of the at least two links, interlocks the first link with the second link such that each tab of the pair of tabs of the first link engages a respective one of the front and back clamping pockets of the second link.
An adjustable length astragal, comprising:
- a housing;
- an upper shoot bolt and a lower shoot bolt positioned adjacent opposite ends of the housing;
- an actuator attached to the housing, connected to and configured to simultaneously extend or retract the upper and lower shoot bolts;
- and
- an adjustable connection assembly provided between the actuator and at least one of the shoot bolts, where the connection assembly adjusts the distance between the actuator and the respective shoot bolt in each of the respective shoot bolt's extended and retracted positions,
- wherein the adjustable connection assembly comprises:
- a linkage between the actuator and at least one of the shoot bolts, the linkage comprising:
- at least two selectively removable interlocking links, wherein the at least two links can be selectively added or removed to adjust the distance between the actuator and the respective shoot bolt,
- wherein the at least two links interlock by rotational motion relative to one another.
