  • preloading of the actuating spring 16 is effective to bias the actuating lever 20 inwardly toward the web 12a of the stile 12, and with the bolt in the projected position as illustrated in FIGS. 5 and 6, the pivot of the spring 16 will be over center with reference to the pivot of the lever 20 on the mounting bracket 22 preventing forcing of the bolt member 15 when the door is bolted.
  • the bolt member 15 is mounted for sliding movement within an edge channel of the door stile l2 and serves the combination function of the bolt assembly and a stile cap. No further stile cap is required over the bolt assembly.
  • the bolt assembly 10 may be used with a door 13 having very narrow stiles 12, as more fully described in my above-mentioned copending application.
  • the bolt assembly 10 is mounted wholly within the edge channel 120, flush with the edge of the door to prevent interference with mating doors,
  • FIGS. 1 through 7 may readily be adapted for double acting operation by mounting opposing levers onto a single mounting bracket with the bolt members projecting upwardly and downwardly therefrom.
  • a bolt assembly could be placed in various positions on the door stile, and advantageously could be operated from the center position of the door. Not only would such mechanism be in a convenient location to operate, but would require less parts to do the same job as two of the. assemblies of the separate mounting brackets.
  • Such a double acting flush bolt is illustrated in the embodiments of FIGS. 8, 9, and 10.
  • the lock stile 12' is of the type formed of an extruded element, such as of aluminum, and provided with relatively heavy face portions interconnected by the transverse web 120. The face portions and web together form the glazing pocket 12b, FIGS. 9 and 10, and an opposed edge channel 120.

  • the edge channel 12c is of somewhat T-shape having undercut portions 12d.
  • the bolt assembly includes a pair of combination stile cap and bolt members 54, hereinafter referred to individually as bolt member, of somewhat T-shaped cross section, so as to be slidably received within the T- shaped edge channel 120 of the door stile 12.
  • the confronting end of one of the bolt members, here shown as member 54 is coped along the web 12a so as to receive a tongue portion 56a of a preloaded actuating leaf spring 56, having the end 56a thereof rigidly secured to the bolt member 54 in any suitable manner, as by screws 57.
  • the other end 56b is pivotally mounted to an actuating lever intermediate its ends by a suitable pin 61.
  • One end of the actuating lever 60 is pivotally mounted to the other one of the bolt members 56 by suitable pin 63.
  • the bolt members 54 and 55 are movable between a retracted position illustrated in FIGS. 8 and 9, with the actuating lever 60 thereof projected down, and a projected position, as illustrated in FIG. 10, with the actuating lever 60 thereof positioned upwardly.
  • the lower end of the leaf spring 56 is bifurcated by a slot 160, FIG. 8, and in addition a slot 55a is formed in the bolt member 55 securing the actuating lever 60.
  • the free end of the actuating lever 60 is provided with and enlarged gripping portion 60a to provide for the manual gripping of the actuating lever. Gripping clearance is'provided in both the leaf spring 56 and the bolt member 55, as shown at 56d and 55b.
  • an arcuate clearance is provided in the bolt member 55 and 55c for the end 56b of the leaf spring 56 and pin 61 when the bolt assembly is in the retracted position.
  • the preloading bias of the leaf spring tends to push the pin 61 and end 56b of the leaf spring inwardly toward the web 12a in both the projected and retracted positions of the bolt assembly 50. Travel of the actuating lever inwardly is arrested by the engagement of the enlarged gripping portion 60a thereof against the leaf spring 56 when the bolt assembly 50 is in the projected position, and by the seating of the lever 60 in the groove 55a in the retracted position.
  • lower end 56b of the leaf spring is over center with reference to the pivot of the lever 60 on the bolt member 55, and accordingly in this locked position it is impossible to force the bolt members 54 and 55 inwardly to release the door.
  • the bolt members 54 and 55 are guided and limited in their movement by suitable pins defining stops, and specifically there is provided a pair of pins 78, 79 each threaded through the transverse web 12a of the lock stile 12 and projecting into guide grooves 54e, 55e
  • the pins 78 and 79 define stops to insure operation of both of the bolt members 54 and 55. Specifically when the bolt assembly is actuated by raising the lever 60 to its upright position, the bolt with the least friction will move first. Once either of the bolts reaches its projected position so as to be limited from further movement by bottoming of its respective pin in its guide groove, the opposite bolt is forced to complete its travel. The same manner of operation occurs when the bolts are retracted. The bolt member with the least friction will move first, until it reaches the limit of its travel as defined by its respective pin and guide slot, and thereafter the other one of the bolt members will be retracted.
  • a projecting bolt assembly for a door comprising:
  • a bolt member adapted to be slidably mounted for projection into a locked position and withdrawal into an unlocked position
