INVENTOR JOHN V. PASTVA JR.

ATTORNEYS United States Patent 3,389,932 D0012 LOCK John V. Pastva, Jr., Parma Heights, Ohio, assignor to The Eastern Company, Cleveland, Ohio, a. corporation of Connecticut Filed Sept. 2, 1966, Ser. No. 576,931 4 Claims. (Cl. 292173) ABSTRACT 015 THE DISCLOSURE A recessed or flush mounted paddle-type lock, either key or nonkey, having a limited number of parts adapted to be economically produced by dieing operation and mountable in a circular opening in a closure member.

The present invention relates to lock devices and more particularly to recessed or flush-mounted paddle-type lock devices, for either key or nonkey locking, mountable in a circular opening in a closure member and intended primarily for use with doors of utility boxes or compartments including doors of utility trucks and the like.

One of the principal objects of the invention is the provision of a new and improved flush-type locking device of the character referred to which is of rugged and durable construction, comprises a relatively small number of parts adapted to be economically produced and assembled, and which can be quickly and easily installed in either right or left-hand doors or the like by the mere provision of a circular opening.

Another provision of the invention is a new and improved lock of the character referred to which includes a flush paddle handle for retracting a slide bolt, springbiased to operating position, and wherein the handle and bolt are operatively connected by a lost-motion means permitting retractive movement of the bolt, as upon the closing of a door in which the lock is installed, without movement of the handle.

The invention resides in certain constructions and arrangements of parts and further objects and advantages of the invention will be apparent from the following description of the preferred embodiment described with references to the accompanying drawings forming a part of this specification in which similar reference characters designate corresponding parts, and in which FIG. 1 is a fragmentary front elevational view of a door and an adjacent door frame having a lock embodying the present invention installed therein;

FIG. 2 is a sectional view with parts in elevation approximately on the line 2-2 of FIG. 1;

FIG. 3 is a sectional view with parts in elevation approximately on the line 33 of FlG. 1;

FIG. 4 is a sectional view with parts in section approximately on the line 44 of FIG. 1; and

FIG. 5 is a fragmentary perspective view of the rear side of the door in which the lock is installed.

The lock of the present invention can be used in different locations and for various purposes, but is especially suitable for use on doors of tool compartments and more particularly on the doors of tool compartments or the like of utility trucks.

Referring to the drawings the preferred embodiment shown therein is designated generally by the reference character A and is installed in a circular opening or recess B in a door C of a tool compartment or the like of a utility vehicle. The door C in its closed position cooperates with adjacent structure such as the post or door frame D to which a striker plate E is attached for latching or locking cooperation with a slide bolt F springbiased to locking position.

The lock A comprises a circular mounting or body 3,389,932 Patented June 25, 1968 ing rearwardly extending portions or members 20 and 21 projecting through slots 22 and 23, respectively, in the bottom 24 of the recess in the body member G for engagement with external abutment surfaces 26 and 26 on the slide bolt F formed by reductions in the width of the sides of the bolt, which is generally channelshaped in cross section with the bottom 27 of the channel lying against the rear side of the bottom wall 24 of the mounting member. Movement of the handle H in a clockwise direction, as viewed in FIG. 2, about the axis of the pin 15 causes the projections 20 and 21 thereof to retract the slide bolt F into its housing member I and withdraw the slide bolt F from the aperture 30 in the keeper plate and the door frame.

The slide bolt F is slidably supported in the bolt housing I which includes flanges welded to the rear side of the bottom 24 of the body member 10 as clearly indicated in FIGS. 2 and 5. The bolt is spring-biased to latching position by a spring 31 interposed in the slide bolt housing between the right-hand end 32 of the bolt, as viewed in FIG. 2, and the right-hand end wall 33 of the bolt housing.

The handle recess 11 in the body member G of the lock is generally semi-circular or cup-shaped for about 220 to 230. The circular part 34 of the recess terminates in a flat side formed of two like spaced aligned portions 35 and 36 having a radially extending aperture or projection 37 which overlies the slide bolt F and within which the extension 17 of the handle H extends and is pivotally connected to the pin 15. In other words, the body member G in addition to the flat bottom 24, previously referred to, has a circular wall 40 throughout the greater portion of its sides, two aligned spaced flat walls 41 and 42 connected by three similar walls 43, 44 and 45 forming the U-shaped aperture or extension 37, previously referred to. The walls mentioned are all normal to the plane of the front part of the body member G which is in the form of a flange 46, the circumference of which is circular. The lock device is symmetrical about the plane on which the sectional view shown in FIG. 2 is taken.

The main or body portion 16 of the handle H is generally flat and is of a configuration which conforms substantially to that of the recess 11 of the body member G except for the right-hand portion 47, as viewed in the drawings, which is cut away or spaced from the side of the recess 11 adjacent thereto and raised slightly to facilitate engagement of the handle member by the fingers of an operator. The rearwardly extending flange 18 about the periphery of the handle conforms generally to the side walls of the recess 11 in the body member G but stops short of the cut away upturned portion of the handle as clearly shown in FIGS. 1 and 2. The portions 48 of the flange 18 adjacent to the wall 44 of the mounting member is shorter than the other portions of thereof, as viewed in FIGS. 1 and 2, of reduced width forming the abutment surfaces 25, 26 against which the projections 21, 22 of the handle H abut to withdraw the bolt upon movement of the handle H in a clockwise direction, as viewed in FIG. 2. The right-hand end of the slide bolt F is slidably supported without undue looseness in the bolt housing I and the right-hand end 32 against which the left-hand end of the spring 31 abuts is formed by an inturned portion of the bottom side 27 of the bolt F. The member 33 against which the opposite or right-hand end of the spring 31 abuts is formed by an inturned portion of one of the sides of the bolt housing 1.

As previously mentioned, the lock of the present invention may be of the nonkey-locking type or the keylocking type. The preferred embodiment shown, however, is of the key-locking type and includes a key-actuated lock cylinder of conventional construction, designated generally as K, mounted in a circular aperture 50 in the handle member H and secured therein by a lock nut 51. Since the lock cylinder K is of commercial con struction it will not be described in detail. Suifice it to say that the lower or rear end of the key-actuated rotatable component of the lock K is provided with a locking member 53 connected thereto by a screw 54. Opposite ends of the locking member 53 are depressed and lie flat against the bottom 24 of the recess 11 in the mounting member G. The rotatable component and the locking member 53 are adapted to be rotated 90 from the position shown in the drawings with the opposite ends of the lock member 53 underneath lugs 57, 58, welded to the bottom 24 of the recess 11 in the mounting plate to a position where they are clear of these lugs. In the position shown, the lugs prevent movement of the handle H about its pivot pin and retraction of the slide bolt F from the keeper E when the door C is closed. When the cylinder component of the lock K and the locking member 53 are rotated 90 from the position shown in the drawings the handle H, which normally rests flush or substantially flush with the flange 46 of the mounting member G, can be rotated to retract the slide bolt F and open the door C.

From the foregoing it will be apparent that the objects of the invention heretofore mentioned and others have been accomplished and that there has been provided a novel and improved paddle-type recessed lock which has a minimum number of parts, is readily manufactured and assembled, can be quickly installed in either right or left-hand doors by mere provision of a cir cular opening therein, and which can be either key-locking or nonkey locking.

While the preferred embodiment of the invention has been illustrated and described in considerable detail, the invention is not limited to the particular construction shown, and it is the intention to cover hereby all adaptations, modifications and arrangements thereof which come within the practice of those skilled in the art to which the invention relates.
