Sept. 10, 1963 w. E. ATKINSON 3,103,114 Y LATCH AND- Loox MEQHANISM Filed July 31, 1962 ATTORNEYS United States Patent O 3,103,114 LATCH AND LOCK MECHANISM Wallace E. Atkinson, Petersburg, Va., assignor to Long Manufacturing Company, Inc., Petersburg, Va., a corporation of Virginia Filed .luly 31, 1962, Ser. No. 213,810 6 Claims. (Cl. 70-71) rIfhe present invention relates to a combined latch and lock structure especially adapted for application to containers or receptacles comprising separable parts to be releasably secured in closed relation.

An object of the present invention is the provision of a combined latch and lock structure which is extremely simple and compact in construction, attractive in appearance, reliable in operation, and capable of manufacture in an economical manner.

Another object of the present invention is the provision of a latch and lock structure having key lock facilities therein which is adapted to be afxed to one of the separable parts of a receptacle and includes a laterally rectilinearly movable external latching member disposed in covering relation to la stationary base plate member aixed to one of the separable parts of the receptacle to` be moved into and out of latching relation with a keeper aiiixed to the other separable part of the receptacle.

Other objects, 'advantages and capabilities of the present invention will 'become apparent from the following detailed description, taken in conjunction with the accompanying drawing, illustrating a preferred embodiment ot the invention.

In the drawing:

FIGURE l is a front elevation view of a combined latch and lock stnucture constructed in accordance with the present invention, shown in latching condition of a portion of a receptacle;

FIGURE 2 is a vertical transverse section view thereof, taken along the line 2-2 of FIGURE 1;

FIGURE 3 is -a vertical longitudinal section view of the combined latch and lock structure taken along the plane indicated by the line 3-3 of FIGURE 2 and showing the parts in .unlatched position;

FIGURE 4 is a section view taken along the same plane as FIGURE 3 but illustrating the parts in latched position; and

FIGURE 5 is a horizontal longitudinal section view taken along the line 5--5 of FIGURE 4.

Referring to the drawing, wherein like lreference characters designate corresponding parts throughout the several figures, the combined latch and lock lstructure of the present invention is indicated generally by the reference character lt) and comp-rises two Igeneral subassemblies or sections, the latching section 11 and the keeper section 12. The latching section 11 is mounted on the front wall of a lower receptacle lbody or tray portion 13 and the keeper section 12 is mounted on the front wall of 'a separable receptacle cover 14, which isjusually hinged to the body portion 13. The plane of separation between the receptacle body and cover is indicated by the reference character l5. The latching section 11 comprises a stationary base plate member 16 which `may be conveniently stamped from sheet metal having a front wall 17, upper yand lower horizontal llanges 18, 19 forming top and bottom horizontal wall members thereof and vertical flanges 2t) and 21 forming vertical end wall members, the latter having rearwardly projecting clinching lugs 22 projecting therefrom adapted to pierce the front wall of the receptacle body portion 13 :and be clinched over against the inner face of the latter to aiiix the base plate member 16 to the receptacle body. An external latching member 2S is mounted upon and encloses the stationary base plate member 16 for Vlaterally reciprocative sliding 31,1031 14 Patented Sept. 10, 1963 ICC movement relative thereto yand forms, in effect, a cover for the stationary base plate member 16 within which the latter is nested. The external latching member 25 is stamped from sheet metal to provide a `fro-nt cover portion 26 in the -form of an inwardly opening hollow shell, having a substantially rectangular, lateral elongated `front wall 27 bound-ed at the top and bottom by a shallow top flange 28 and a deeper bottom flange 29, and at the ends thereof by vertical llanges 3G, 31 Aforming end walls.V Nested Within this front cover portion 26 is a backing member 32 of sheet metal 1dimensioned to be received in nested relation within the front cover portion 26, having a rear wall 33 `disposed to lie in parallelism with the iront wall 27 of the front cover portion 26I in alignment With the rear edge of the top ange 23, the backing member 32- having forwardly projecting top and bottom flanges 34 and 35 to maintain the proper spacing between the rear wall 33 and the front wall 27 of the `front cover portion 26. Rearwai'dly projecting stops y36 extend a short `distance from the lateral margins of the rear wall 33 about which retaining lugs 37 on the end wall lianges 30, 31 of the front cover portion 26 are bent to retain the backing member and front cover portion :in assembled relation.

The external latching member 25 is assembled with the 'base plate member 16 for latenal rectilinear sliding movement relative to the stationary base plate member, the rear wall 33 of the backing member 32 having a pair of rearwardly projecting guide lugs 3S, which extend through laterally elongated and aligned slots 17a in 'the front wall 17 of the base plate member 16. The upper 'and lower edges of the slots 17a are spaced Jtrom each other substantially in conformity to the vertical width of the guide lugs 38 to guide the external latching member 25 in a rectilinear path sidewise or laterally of the external latch member 25. A leaf spring retainer 39 lies against the back of the fro-nt wall 17 between the guide 'lugs 38` and is retained in this position to hold the members 25 and 16 in relatively slidable assembled condition by the ends of the lugs 38 which are Ibent against the retainer. The retainer spring 39 in the preferred embodiment herein illustrated is of greater height than the slots 17a to lap bounding portions of the front wall 17 and has recesses 39a at the opposite ends to receive the :lugs 38 and raised formations 39b bounding the bases of the recesses 39a against which the lugs 38 are ibent. Additionally, the Ibottom flange 19 of the base plate member 16 slidably bears 'against the bottom flange 29 or" the front cover portion 26 of the external latching member 2S and the front wall 17 has a pair of laterally aligned forwardly bent lock tongues 40 which project into a rectilinear slot 41 in the rear wall 33 of the backing member 32, al1

cooperating to guide the external latching member 25 in the preselected rectilinear path of lateral movement.

The top flange 18 of the base plate member 16 has a pair of upwardly projecting alignment tongues 42 adapted to project into complementary slots 43 in the lower wall of ilange 44 of the keeper section`12, the keeper section being in the -form of a laterally elongated keeper bar having a length corresponding substantially :to the length of the front cover portion 26 of the external latching member 25 and being designed to be secured to the front Wall of the upper part or cover y14 of the receptacle. In the preferred embodiment, the keeper section 12 is formed of sheet metal 'and includes a -front Wall 45, a top ilange 46 paralleling and corresponding in depth to the bottom flange 44, and end ilanges 47 of similar depth at the llongitudinal ends of the keeper bar.. `A hook or catch tongue 48 having a catch shoulder 49 is bent rearwardly from the rear wall 33 of the backing member 32 of the external latching member assembly 25, the catch tongue 48 having a working hook portion disposed in rearwardly oifset parallel relation to the rear Wall 33 which .is designed to be received within an interlocking slot 50 formed in the lower ange 44 of the keeper section 12. When the external latching member 215 is shifted laterally to its unlocking limit position illustrated in FIGURE 3 wherein the rnernber 25 is laterally 0E- set relative lto the keeper `12, the catch tongue 48 is aligned vertically with 4the interlocking slot 50 in the keeper 12 and the `alignment tongues 42 on the base plate member 16 are aligned with the associated slots 43 in the keeper 12. In this condition, the keeper 12 and the receptacle cover 14 on which the keeper is mounted can be shifted vertically relative to each other to withdraw the catch tongue 48 from the interlocking slot 50, thus permitting opening of the receptacle cover 14. When the receptacle cover is in closed condition and the alignment tongues 42 and catch tongue 48 are projected fully through the associated slots 43 and 50 of the keeper 12, the external latching member 25 may be shifted laterally into alignment with the keeper 12 to the locking limit position illustrated in FIGURE 4, during which the working hook shaped part of the catch tongue 48 is shifted Ilatera'lly within the keeper section v12 relative to the keeper to locate the catch shoulder 49 over the bordering portions of the lower flange 44 of the keeper 12 adjacent the interlock slot 50 and thereby interlock Ithe keeper and latching sections against separation.

To eiect key locking of the external latching member 25 in this locking limit position, a simple locking mechanism in the #form of a disc-like bolt 51 is supported tor rotation about its central axis in the circular way 52 pressed in the rear vv-all 33 of the backing member 32 and shaped to complement the bolt 51. The bolt 51 is in the shape of a truncated disc cut along a chord so that the at 53 lies flush 'with the upper edge of the slot 41 in the rear wall 33 of the backing member 32 when the bolt 51 is in unlocking position. The bolt 51 has one or more indentations or sockets 54 lin the rear face thereof to register with a restraining detent or detents 55 in the rear -wall 33 at the unlocking position and at a locking position spaced 180 from the unlocking position wherein a segment of the bolt 51 projects below the upper edge of the slot 41. The spaced lock tongues which project through the slot 41 from the front wall 17 of the base plate member 16 are spaced apart a distance corresponding substantially to the chordal length of that portion of the bolt 511 which registers with the slot 41,

the -lock tongues 40 being located to ank the bolt 51 when the external latching member 25 is in the locking limit position. The usual key barrel 56 is disposed forwardly of the bolt 51 .and projects through a suitable circular opening in the front wall 27 of the front cover portion 26.

It will be apparent that when a key is inserted into the key barrel 56 and bolt 51 and rotated to align the flat 53 of the bolt with the slot 41, the lock tongues 40l are then freed for movement along the slot 41. The external latching member 2S may `then be' shifted laterally to the position illustrated in FIGURE 3, which brings the catch tongue 48 into alignment with `the interlock slot 50 of thel keeper so that the catch tongue 48 may freely pass through the catch slot and be withdrawn therefrom upon opening movement of the receptacle cover 14.

When the receptacle cover 14 is lowered to closed condition relative to `the receptacle body portion 13, the external latching member 25 may lthen be shifted laterally to the locking limit position illustrated in FIG- URE 4, which effects interlocking of the catch tongue 48 and the keeper 12 to prevent relative opening movement of the -tWo receptacle parts. Rotation of the bolt 5`1 by the key to bring an uninterrupted portion of the bolt into registry with hte slot 41 between the lock tongues 40` of the base plate member 16 locks the latching member 25 against displacement from the locking limit position.

While but one preferred example of the present invention has been particularly shown and described, it is apparent that various modifications may be made therein the invention as .are imposed by the prior art and set forth in the appended claims.
