Patented Jan. 12, 1954 UNITED STATES ATENT OFFICE LOCKABLE LATCH STRUCTURE FOR VERTI- CALLY SLIDABLE DOORS Application November 3, 1950, Serial No. 193,960
3' Claims. (01. 292-177) This invention relates to improvements in lockable latch structure for vertically slidable doors.
The principal objects of this invention are:
First, to provide a simple and inexpensive yet effective latch and lock structure for doors of the vertically slidably opening type.
Second, to provide a latch structure which is easily assembled and installed on a door.
Third, to provide a lockable latch structure which is spring biased to unlocked position so as to automatically unlatch the door when the lock mechanism is unlocked.
Fourth, to provide a door latch structure adapted to cooperate with a standard key operated lock and bolt so that the latch structure may be locked by the lock bolt.
Fifth, to provide a latch structure for a vertically slidable door which maybe employed as a simple non-lockable latch and later converted to a lockable latch by the addition of a key operated lock bolt.
Other objects and advantages relating to details and economies of my invention will be apparent from a consideration of the following description and claims. The drawings, of which there is one sheet, illustrate a preferred form of my latch and lock structure.
Fig. l is a fragmentary front or outside elevational view of a door with my latch and lock structure in place thereon.
Fig. 2 is a fragmentary inside elevational view of the latch and lock structure installed on a door.
Fig. 3 is an enlarged fragmentary inside elevational view of the latch and lock with the cover for the latch partially broken away in vertical section.
Fig. 4 is a fragmentary cross sectional view through the latch structure taken along the plane of the line 4-4 of Fig. 3.
In the drawings I have illustrated a doorll of the vertically slidable type mounted within a door opening formed in part by the side frame member 2. Doors of this type are commonly made up of several horizontally elongated sections 3 joined together by hinge structures 4. The hinge structures are provided with guide rollers 5, which are arranged to travel in a guide rail 6 mounted on the side frame 2 along the inner side of the door opening.
My latch structure includes a housing I mounted along one edge of the inner surface of the door and provided with a latch bolt 8 adapted to be extended into locking engagement'with a keeper surface desirably formed in the side of the guide rail 5. An inner handle 9 is provided for operating the latch structure, and a key operated lock It is positioned above the housing 1 to cooperate with the latch structure, as will be described in detail presently. A manually operable knob l l is provided on the lock for operation from the inner side of the door, as is common in locks of this type. The lock is provided with a lock cylinder and key hole I2 opening to the outer surface of the door, and an outer latch handle is is provided for operating the latch from the outside of the door.
As is most clearly illustrated in Figs. 3 and 4, the latch structure consists of an inwardly opening channel shaped base member l4 having its web portion. secured to the inner surface of the door as by the screws IS with its channel flanges 16 disposed vertically of the door. The web of the base l4 defines an opening I? for the door handle shaft I8, which extends through the door.
and latch housing as illustrated. At least the middle portion of the handle shaft it within the latch housing and preferably the entire shaft is of non-circular cross section.
A latch operating arm It has a non-circular hole formed in one end thereof and is non-rotatably received over the handle shaft [8 within the housing I. The arm l9 has a slot 20 formed therein and extending radially from the handle,
and the slot slidably receives a pin 2| secured to the latch bolt 8 so that rotation or oscillation of the handle shaft and latch arm will reciprocate the latch bolt between door latching and unlatching positions.
The latch bolt 8 is guidingly supported in inwardly opening notches 22 formed in the side flanges It of the base. The latch bolt is retained in the notches by the cover 23 of the housing 7. The cover is also of channel shaped cross section and fits telescopically over the base member M. The side flanges of the cover are notched from their forward or outer edges as at 24 to cooperate with the notches 22 in the base in forming guide openings for the latch bolt 8. Laterally outwardly turned ears 25 on the cover permit its easy attachment to the door by the screws 26.
The outer door handle it and the inner door handle 9 are non-rotatably secured to the handle shaft I 8 in any of several convenient methods.
i3 to bias the handles and shaft inwardly of the door and prevent rattling.
The latch structure thus far described is obviously operative to latch the door and can be operated from either the inside or outside of the door. In order that the latch structure can be immediately or later converted to a spring biased lockablelatch the upper end ofthelatchoperating arm 19 is provided with an arcuate bolt blocking edge 29 with a bolt receiving notch 30 formed therein. The notch 36 is angularly arranged on the arm [9 so as to face outwardly and upwardly of the housing when the latch: bolt 8 is in latched position as shown in Fig; 3. The bolt blocking edge 29 terminates in a spring. anchor hook or notch 35. The side; flanges; L6. of the base are provided with inwardly struck anchor ears 32 on each side of theshaft L8 In converting the latch to a spring biased latch, the cover 23, latch bolt- 8 and latch operating arm 13 are removed inwardly of the handle shaft l8, and a double coil spring, 33 is placed sidewise overthe latchoperating arm- 19 with half of the coilsof the spring on each side of the arm, as is best illustrated in Fig. 4. The adjacent turns of J the two sections of the spring 33 are connected by a U-shaped integral extension 35- of the spring wire which engages the anchor notch- 3-iofthe latch operating arm, as shown in Fig. 3. The outer ends'of: thespring- 33 are extended in fixed anchors 35-, and the ends of these anchors 35 are engaged with one of thelocking ears 32 in the base member as the spring and latch operatingarmare-reassembled-axially over the handle shaft i8; It will be noted that the lower end of the latch: operatingv arm i9 is axially offset as at 36 sothat the latch: bolt, operating arm and spring canbe assembled in either right or left hand posi-- tionrelative to the base member for operation along the right or left hand sides of a door. After the latch bolt and spring. are assembled on thebasewith: the bolt in unlatched position and the spring. 33 in substantially unstressed.
condition, the: inner cover: 23: and; handle 27s are.
installed as previously described.
The. lock housing I ll can thexrbe. easily mounted on. the inner surface of the door immediately. above the housing. I. and with the lock bolt 3.2; directed downwardly toward the. latch structure.
Notethat in the unlatched position. of the.op.erat-- ing arm, L9,. the; lock; bolt. 3] will engage and, be.
held. in. retracted. position. by the. blocking edge: 29; on the; end of. the. latch. operating. arrm. As: the: latch bolt andoperating. arnrare: rotated to. door latching position by either of the. door bane dles,,the.-locking notch 30 will come into-registry with the lock bolt 3.1. and the bolt: will extend into lockingjengagement therewith. Preferably thelock I is of the self-closing, spring pressed type which. automatically engages the; bolt with.
the latchv arm. Concurrently the. spring 33 willv have been tensioned. so that later retraction of the lock bolt, either by use. of a key fromthe out.- side of the. door or by operation of the knob H,
willresult in the latch operating arm. and latch.
bolt being automatically retracted.
Having thus described my invention, what I.
claim as new and desire to. secure by. Letters Patent is:
