' Int. Cl. Ec 1/12 US. 'Cl. 292-173 1 Claim ABSTRACT OF THE DISCLOSURE V A recessed or flush mounted paddle-type look, either key or non-key, 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 locking mechanism consists of a spring projected sliding bolt Operated by a pivoted lever. The lever is mounted in a substantially rectangular depression having one arcuate side wall and disposed in a circular plate.

The present invention relates to lock devices and more particularly to paddle-type recessed or flush-mounted locks, either key or non-key locking, intended primarily for use with doors of utility boxes or compartments, such as commonly employed on utility trucks and the like.

One of the principal objects of the invention is the provision of a new and improved paddle-type recessed door lock of the character referred to which is ofdurable construction, reliable in operation and comprises a relatively small number of parts adapted to be economically produced and assembled, and which can be quickly and easily installed in either rightor 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 paddle-type handle for retracting a slide bolt, spring-biased 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 reference 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 3-3 of FIG. 1; and

FIG. 4 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 the like, and more particularly on the doors of tool compartments of utility trucks.

Referring to the drawings the preferred embodiment of the invention shown therein is designated generally by the reference character A. The lock A is shown installed in a circular opening or recess B in a door C of a tool compartment or the like of a utility truck. The compartment closed by the door C comprises a door frame D to which a striker plate E is engaged when the ice door is closed by a slide bolt F spring-biased to locking position.

The lock A comprises a sheet metal mounting or body member G, die-formed so as to provide the member with a forwardly facing opening or recess 11 surrounded by a flange 12, the circumference of which is circular. The recess 11 is generally rectangular in shape having two opposite parallel

straight walls

15 and 16 connected at their left-hand ends, as viewed in FIGS. 1 and 2 of the drawings, by a straight end wall 17. The right-hand ends of the

walls

15 and 16 are connected by an arcuate wall 18 which extends over an arc of approximately to The wall 18 and the corners formed by the junction of the

walls

15 and 17 and the

walls

16 and 17 lie in the circumference of a circle, the center of which is the center of a key device H mounted in a paddle-type handle I.

The bolt F is slidably supported in a sheet metal channel-shaped bolt housing K fixedly secured to the rear side of the bottom wall 20 of the recess 11 in the mounting member G, by having flanges 21 and 22 along opposite sides of the channel-portion thereof spot welded to the 'wall 20. The

opposite sides

23 and 24 of the bolt housing K are parallel with and equally spaced from the

sides

15 and 16, respectively, of the mounting member with the result that the bolt F reciprocates in a path which is normal to the wall 17 and is symmetrical about the section line 22. The paddle-type handle I, also made of sheet metal or plate, is received in the recess 11 of the mounting member G and the shape thereof conforms generally to the shape of the recess with the exception of the right-hand end thereof which is spaced from the arcuate wall 18 of the recess and has a slightly upturned edge or portion 25 so that the fingers of an operator can be readily inserted thereunder.

The handle I, with the exception of the right-hand side, is provided with downwardly extending

flanges

26, 27 and 28 along the straight sides thereof adjacent to the

sides

15, 16 and 17, respectively, of the recess and is pivotally connected to the mounting member adjacent to its left-hand end of the recess 11 by a pivot pin 30 extending through the

side walls

15 and 16 of the mounting member and the

flanges

26 and 27 of the handle adjacent thereto. The flange 28 of the handle I adjacent to the wall 17 of the mounting member is relatively short compared to the

other flanges

26 and 27.

The slide bolt F has a longitudinally extending groove 35 in the left-hand end thereof and opening into the side thereof adjacent to the bottom wall 20 of the recess 11 of the mounting member G, the right-hand end wall 36 of which is normal to the bottom 20 of the mounting member and is engaged by an abutment face 37 on a projecting end 38 of a member 40 welded to the underside of a flat portion 41 of the handle I. The projection 38 of the member 40 extends through a slot 42 in the bottom 20 of the mounting member G. The pivot pin 30 extends through the member 40 and the construction is such that rotation of the handle I in a crosswise direction, as viewed in FIG. 2, about the pivot pin 30 causes the abutment face 37 of the member 40 to cooperate with the right-hand wall 36 of the slot 35- in the bolt F to retract the bolt against the bias of a spring 44 interposed between the right-hand end of the bolt F and a member 45 located in the right-hand end of the bolt housing K and retained therein by intumed flanges on

opposite side walls

23 and 24 of the bolt housing. Theslot 35 in the bolt F is of suflicient length to allow the bolt to retract into the bolt housing upon the closing of the door C without causing movement of the handle I, which handle is normally retained in the recess 11 of the mounting member in the position shown in FIGS. 1 and 2 by the bias of the spring 44. The left-hand end of the slot 42 is such as to limit the movement of the handle I in a counterclockwise direction, as viewed in FIG. 2, if the lock mechanism H is not employed, as hereinafter mentioned.

As previously mentioned, the lock of the present invention may be of the non-key-locking type or the key-locking type. The preferred embodiment shown, however, is of the key-locking type and the lock device H includes a key-actuated lock cylinder 45 of conventional construction mounted in a circular aperture in the handle member I and secured therein by a lock nut '47. Since the lock cylinder is of commercial construction it will not be described in detail. Suflice it to say that the lower or rear end of the key-actuated rotatable component of the lock cylinder is provided with a locking member 50 connected thereto by a screw 54. Opposite ends of the locking member 50 are depressed and lie flat again-st the bottom wall 20 of the recess 11 in the mounting member G. The rotatable component and the locking member 50 are adapted to be rotated 90 from the position shown in the drawings with the opposite ends of the lock member 50 underneath lugs 52 and 53, welded to the bottom wall 20 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 I about its pivot pin 30 and retraction of the slide bolt F from the keeper E when the door C is closed. When the cylinder component of the lock device H and the locking member 50 are rotated 90 from the position shown in the drawings the handle I, which normally rests flush or substantially flush with the flange 12 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 rightor left-hand doors by mere provision of a circular opening therein, and which can be either key-locking or non-keylocking.

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.

What I claim is:

1. A lock device of the character described comprising a plate-like die formed sheet metal mounting member having a front opening recess generally rectangular in plan except for one side which is arcuate and of a curvature such that the opposite corners of the recess lie or substantially lie on a continuation thereof, said recess being surrounded by a flange the periphery of which is circular and having a planar rear or bottom wall connected to said flange by a continuous wide wall and having a slot therein parallel with the two side wall portions of said recess in said mounting member adjacent to the arcuate portion thereof, a sheet metal bolt housing secured to the rear side of said bottom wall of said recess in said mounting member, said bolt housing being generally channel-shaped in cross section, a slide bolt slidably supported in said bolt housing and having an end portion thereof normally projecting from said bolt housing and an abutment surface facing in the direction of said end portion, spring means biasing said slide bolt to a projected position with respect to said bolt housing, a sheet metal padd1e-type handle having a relatively flat front body portion normally lying substantially in the plane of said flange of said mounting member and conforming generally with the shape of said recess in said mounting member except for a portion adjacent to said arcuate side of said recess which portion is curved slightly outwardly of said recess and is spaced from the adjacent arcuate side of said recess and concave with respect to the surface of said arcuate side wall portion of said recess for the projection of the fingers of an operator to a position underneath the adjacent rear side of said handle, said body portion of said handle having rearwardly extending flanges along opposite parallel sides and a sheet metal member fixed thereto and extending through said slot in said bottom Wall of said mounting member normally engaging said abutment surface on said slide bolt formed by said slot therein, and means including a pintle pin extending through aligned apertures in said two side wall portions of said recess adjacent to said arcuate portion and said rearwardly extending flanges on said handle member.
