No. 209,098, filed Dec. 17, 1971, now abandoned.

The present application relates to a novel latch and lock assembly including a housing adapted to be mounted in an opening in a cabinet door, drawer or other closure, and a spring-biased combination handle and latch bolt, both formed or molded of a plastic composition which snap together in a positive and secure assembly.

Another important object of the present construction is the provision of a novel flush mounted latch assembly and locking means designed and constructed primarily for use in recreational vehicles and the like.

A further object of the present assembly is the provision of a novel two-part flush mounted latch assembly comprising a cylindrical housing received and frictionally mounted in a conforming opening in a closure such as a door or front panel of a drawer, and a novel combination handle and latch bolt mounted in the housing, the latch bolt having a flexible tab for spring-biasing the latch bolt to latching engagement for positive latching of the closure.

Further objects are to provide a construction of maximum simplicity, efficiency, economy and ease of assembly and operation, and such further objects, advantages, and capabilities as will later more fully appear and are inherently possessed thereby.

Referring to the novel illustrative embodiment of the latch bolt handle and housing assembly of FIGS. 1 to 12, inclusive, the assembly includes a flush mounted housing 10 of cylindrical form conformably received and retained in an opening 11 of a cabinet door or closure 12, or adapted tobe mounted in the front panel of a drawer, such as for use in a recreational vehicle or the like although not limited thereto. In the. housing is mounted a latch bolt 13 having a plate-like handle 14 for releasably actuating the latch bolt whereby its hook end or latching projection 15 is readily released from engagement with a strike, latching shoulder or abutment 16 for retaining the door or drawer closed.

The handle 14 covers approximately one-half the from opening 17 of the housing leaving adequatespace for the operator to insert one or more fingers in the open space 18 to grasp the upper edge 19 of the handle 14 (see FIG. 5) and withdraw and pivot the upper edge 19 of the handle about lateral projections 21,21 received in open recesses 20,20 in spaced embossments or shoulders 22,22 on the interior of the housing 10,

and about which the integral combined handle 14 and latch bolt 13 are pivotally mounted.

The rear wall 23 of the housing 10 has a vertical slot 24 aligned with a slot 25 between the embossments or shoulders 22,22 receiving in the slot 25 the forward end 26 of the latch bolt 13 formed integral with the handle M, with the rearwardly projecting portion of the leg 27 of the latch bolt 13 extending through and to the rear of the slot 24 in the rear wall 23 of the housing. The hook end or latching projection 15 of the latch bolt is spring-biased to latching position when the door or drawer is moved to closed position and the hook end engages the shoulder or strike 16, and this end is inclined to facilitate its being elevated when moved toward latching engagement.

To spring-bias the latch bolt 13 to closed position, the bolt is provided with an integral flexible tab 28 abutting the edge 29 of the slot 24 in the rear wall 23 of the housing 10 and as the tab and the bolt 13 are formed of a suitable plastic composition and the tab is flexible, this tab spring-biases the latch bolt to latching engagement about the pivot or projections 21. The tab 28 has a projection 30 on the free end to limit movement thereof.

The housing 10 forming one part and the combined handle and latch bolt 13 with its tab 28 forming the other part of the assembly, are molded or formed of a suitable plastic composition such as nylon with the tab 28 having sufficient inherent resiliency for springbiasing the latch bolt toward latching position, and the housing 10 frictionally retained in the opening 11, the housing having a limiting external flange 29 for locating the housing in the opening of the closure.

In this assembly the components consist of two parts which snap together; namely, the housing-10 and the combined handle and latch bolt consisting of the bandle 14 and latch bolt '13 having the spaced projections 21,21 snapping into the open end of the recesses of the spaced shoulders 22,22.

In the alternate embodiment of FIGS. 13 to 23, inclusive, the housing 31 is similar to.the housing 10 except for the location and mounting of a pin 32 in the shoulders 33,33 about which pin the latch bolt 34 and integral handle 35 are adapted to pivot. The plate-like handle 35 substantially conforms to the handle 14 except for the contour of its upper edge 36, but the latch bolt 34 has a leg 37 with its forward or outer end 38 integral or affixed to the handle 35 whereby the handle and latch bolt pivot about the pin 32 in the slot 39 formed between the shoulders 33,33 in the housing 31, the outer end of the latch bolt having an open recess 40 receiving the pin 32 as shown in FIG. 23.

The latch bolt projects through the slot 41 in the rear wall 42 of the housing 31 and its rear or inner hook end 43 has a forwardly projecting flexible tab 44 maintained in contact with the edge 45 of the slot 41 with the movement of the latch bolt 34 limited by a projection 46 on the free end of the tab, the latter springbiasing the latchbolt toward latching position. In this embodiment the pin 32 is projected through the aligned openings in the spaced shoulders 33,33 with the two component parts; namely, the housing 31 and the combined latch bolt-34 and handle 35, snapped in position with the pin 32 received in the recess 40 adjacent the forward or outer end of the latch bolt 34.

To securely mount and retain either housing 10 or 31 in the opening of a door, closure or in a drawer, the outer circumference of the housing is provided with equally spaced plural tapered ribs 47.

FIGS. 24 to 28, inclusive, disclose the handle, latch bolt and housing assembly of the embodiment of FIGS. 1 to 13, inclusive, provided with a key-operated cabinet or cylinder lock 48 in which insertion and rotation of the proper key moves a swing bolt or cam 49 to and out of locking position relative to the latch bolt 13. When the swing bolt or cam 49 is rotated andits free end moved downwardly over and in aligned position with the latch bolt 13, the latter is retained against release until the key 50 is inserted and rotated to swing the bolt of its adjusted positions which are 90 apart, the swing bolt or cam is retained locked in either position.

Although the cylinder lock with its swing bolt or cam are shown in the embodiment of FIGS. 1 to 13, inclusive, it is clearly evident such may also be embodied in the alternate form of FIGS. 14 to 23, inclusive.
