Abstract
A locking astragal for attaching to an inactive leaf of a double doorway. In the illustrated embodiment, an elongated astragal casing has a channel and bolt-slide assemblies mounted slidably within the channel. Each bolt-slide assembly includes a latching member and bolt. By depressing the latching member, the latching member can slide through the channel to extend and lock the bolts into indentations in the upper and lower surfaces of the door frame. The bolts may also be retracted back into the astragal to open the inactive leaf. In the illustrated embodiment, each latching member has an integral spring which simplifies fabrication and assembly.
Claims18
An astragal, comprising:
- an elongated casing having opposing ends and a casing aperture arranged between the opposing ends;
- at least one locking bolt slidably positioned near at least one of the ends of the elongated casing, each locking bolt sliding between a first and second position;
- at least one bolt latching member for selectively latching an associated locking bolt in the first and second positions, the latching member being pivotable between a latched position substantially within the caging aperture such that the locking bolt is latched and a released position substantially outside the casing aperture such that the locking bolt is unlatched, the latching member having an integral spring portion for biasing the latching member in the latched position.
An astragal, comprising:
- an elongated casing having opposing ends;
- at least one locking bolt slidably positioned near at least one of the ends of the elongated casing, each locking bolt sliding between a first position and a second position;
- at least one bolt latching member for selectively latching an associated locking bolt in the first and second positions, the latching member including integral trunnions and being pivotable about the integral trunnions between a latched position in which the locking bolt is latched and a released position in which the locking bolt is unlatched, the latching member further including an integral spring portion for biasing the latching member in the latched position.
An astragal assembly for sealing a spacing between an active leaf and an inactive leaf of a double doorway within a door frame, the astragal being fastened to the inactive door and adapted to be received by indentations in the door frame, the astragal comprising:
- an elongated casing provided with upper and lower channels at opposing ends of the casing;
- upper and lower locking bolts slidably positioned within the upper and lower channels, respectively, of the elongated casing, the bolts engaging the indentations in the door frame, each bolt sliding between a first extended position and a second retracted position;
- upper and lower bolt actuating means slidably disposed within the upper and lower channels, respectively, for selectively latching the locking bolts in the first and second positions, the actuating means comprising
- a rectangular pull block provided with trunnion bearings, and
- an elongated latching member having trunnions pivotally mounted in the trunnion bearings of the pull block and having a manually actuable lever arm, a latching dog and an integral spring tail extending from the latching member for biasing the latching member in a latched position, the latching member being pivotable between the latched position in which the lever arm is released and an unlatched position in which the lever arm is depressed, wherein the latching member flexes at a crease when the lever arm is depressed;
- upper and lower slide plates adapted to be slidably coupled to the bolt actuating means, each slide plate having at least a retracted position locking aperture and an extended position locking aperture, the apertures for receiving the latching dog of the latching member when the lever arm of the latching member is released and in the latched position, wherein
- when the latching member is depressed, the latching member flexes at the crease and disengages the latching dog from one of the apertures, enabling the bolt actuating means to slide over the associated slide plate to engage another aperture.
An astragal assembly, comprising:
- an elongated casing having opposing ends and opposing sides;
- and
- at least one bolt-slide assembly coupled to at least one of the ends of the casing, the at least one bolt-slide assembly comprising
- a locking bolt, and
- a latching member coupled to the locking bolt, the latching member having an edge portion and a spring portion, the spring portion contacting one side of the casing to bias the edge portion against the other side of the casing to selectively latch the locking bolt;
- wherein the latching member may be depressed by an operator when the astragal is in an assembled state to disengage the edge portion from the casing so that the latching member may be slid within the casing.
An astragal assembly for sealing a spacing between an active leaf and an inactive leaf of a double doorway within a door frame, the astragal being fastened to the inactive leaf and adapted to be received by indentations in the door frame, the astragal comprising:
- an elongated casing provided with upper and lower channels at opposing ends of the casing, the channels having a bottom surface;
- and
- at least one bolt-slide assembly coupled to the channels at the ends of the casing, the bolt-slide assembly comprising
- upper and lower locking bolts slidably positioned within the upper and lower channels, respectively, of the elongated casing, the bolts locking into the indentations in the door frame, and
- upper and lower latching members coupled to the upper and lower locking bolts, each latching member having an elongated body and a downwardly angled spring arm, the elongated body and spring arm together defining an integral spring portion for frictionally engaging the latching member to the associated channel to selectively latch the associated locking bolt, wherein
- when the elongated body is depressed, the spring arm flattens outwardly adjacent the bottom surface of the channel such that the latching member can slide through the associated channel in the casing, and when the elongated body is released the latching member is frictionally engaged in the channel.
In an improved astragal assembly comprising an elongated casing provided with a channel positioned axially through the casing, upper and lower locking bolts slidable within the channel, and upper and lower actuating means coupled to the respective locking bolts, the improvement comprising:
- upper and lower latching members mounted within the upper and lower actuating means, respectively, for selectively latching an associated locking bolt, each latching member being pivotable between a latched position in which the locking bolt is latched and a released position in which the locking bolt is unlatched when the astragal is in an assembled state, the latching member having an integral spring portion for biasing the latching member in the latched position.
