Filed Aug. 13, 1962, Ser. No. 216,414 14 Claims. (CL' 7-100) This invention relates to lock and handle means for main objects of this invention vertically acting doors. The
are, Y i.
First, to provide `a door lock and door manipulating handle means which includes means yfor locking the door, preventing opening thereof from the outer side of the door. While permitting opening lfrom the inner side of the door when said -outer side means is locked.
Second, to provide a door locking and manipulating means having the stated advantages which is easily manipulated for opening the locked door from the inner side thereof.
type, the door and the track beingrshown mainly in `conventional form. y
FIG. 2 is a fragmentary inside .view -With the bolts in Vprojected position.
PEG. 3 is a fragmentary View corresponding t-o that of i F16. Z'With the bolts in retracted position, their` projected position being indicated by dotted lines.
FIG. 4 is an enlarged fragmentary View on a line corresponding to `line 4-4 of FIG. 3. Y
FIG. 5 is a fragmentary'sectional view corre-spending to that of FIG. 4 lwith the'inner bolt actuating member,
retracted or disengaged from the spindle coupling mernber to prevent operation of the bolts from the outside of the door when the door is locked, but one in which the Y bolts can be disengaged 4from their keepers lfrom the inside of the door. i
FIG. 6 is .ayfragmentary v iew in section on a line corresponding to line 6--6 of FIG. 2.
in the accompanying drawing, I illustrate my invention .i
in connection with an upwardly act-ing door, designated generally by the numeral =1, and comprising four section-s 2 hingedly connected by hing-es y3. The door frame, designated `generally by the numeral 4, is provided with tracks 5 engaged by rollers d mounted on the .door desirably on the hinges. This feat-ure, however, 'forms no part of the present invention and therefore the details are not illustrated. The tracks include horizontal portions to' Isupportedly receive the door when in its open position, but these are not illustrated as such tracks are well known and in extensive commercial use, I
The lock means of the embodiment of my invention illustrated comprise a pair of elongated bar-like bolts 7 Which are slidably mounted at their outer ends on the supporting bracket-like Way members 8 of angled cross section and having holes 9 therein slidably receiving the 3,187,526 Patented June 8, 19165 ice bolts. `Desirably these way members 8 have vertical slots 10 with which the screws 11 are clampingly engaged to align the outer ends of the bolts with the slet-like keeper openings 12 provided therefor in the rails 5. The bolts when in retracted position as shown in FIG. 3 clear Othe `rails and they lie entirely on the inner side of the door.
The bolt actuating `and locking means comprise -the spindle 13 rotatablymounted on the bracket 14 which is secured to the outer side of the door by the screws 15. The handle 16 which is lan integral part of the lock uni-t 17 is mounted on the outer end of t-he spindle 13 and -is connected to and disengaged from the outside of the door by means of the key 18 shown by dotted lines in FIG. 5. The details of 'the key controlled lock means are not illustrated, as lock means for handles of the type illustrated are widely -used commercially. It will be understood that the lock means is designedto detachably connect the han- 4die to the spindle, that is, when the lock means is adjusted side of the bracket is a coupling member 22 having an ,opening 23 therein adapted to receive the lug or detent 24 .on .the inner bolt actuating member 25, which is provided with a handle 26 at its upper end land has an opening 27 therein through Which 'the spindle projects and dimen- ,sioned topermit tilting of the bolt actuating member 25 relative to the-spindle, see FIGS. 4 and 5.
1 `One of the bolts 7 is connected 'to the member 25 by the pivot 28 disposed above the spindle 13 and` the other -by the pivot 29 disposed below the spindle. The bolts are simultaneously projected and retracted by manipulation of the handle 16 from the outside of the door when the handle is operatively connected to the spindle. and the 4bolts may be manipulated from the inside of the door by means ofthe handle 26 with the handle 16 in locked or unlocked position by disengaging the lug 24 from the keeper porti-on 23 on the coupling member 22, `as is illus- `trated in FIG. 5. The spring 37 on the spindle automati- .Gally engages the lug 24 of the coupling member when the bolts are in projected position. To insure complete actuation of the bolts 7 to and from their locking and their unlockingpositions, I provide the rod-like spring support "member 30 having 'an eye 31 at its upper end which engages the pin or stud 29 connecting .one of the bolt members 7 to the lower end of the bolt actuating and coupling member 25.
The coiled spring 32 is mounted on this member 3.0 which is reciprocatingly supported and guided by the :forwWardly projecting lug 33 on the lower end of the bracket r19, the rod 30 -being slidably and guidingly disposed `through a hole 34 provided `therefor in the bracket 33. .The member 30 is provided with a spring thrust collar 35 Afor the upper end of the spring. :As illustrated in FIG. 3 by full lines and dotted lines, lthe connection to the bolt actuating member is such that the spring acts to hold the `bolt actuating member in bolt retracting position as illusy tratedby full lines in FIG. 3 and in its actuated position bydotted lines in FIG. 3.
Vare in retracted position, 4see FIG. 3. The handle 26, in
the embodiment illustrated, serves as a sto-p to engage the other lbolt 7 when the parts are adjusted to bolt projecting position, `see FIG. 2. With the par-ts thus arranged, upwardly acting or vertically acting doors of substantial Width may be elf-ectively locked in closed position and at the same time when locked against any lmanipulation from outside the bolts may be retracted from the inner side of the door yand the door may be closed and manipulated from the inner side of the door without unlocking the lock unit 17 of the handle 16.
I have illustrated and described my invention in a highl1y practical-commercial embodiment thereof. I have not attemptedto illustrate and describe other modifications or embodiments, as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired. t
