Eb 9/08; E05c 21/00 U.S. Cl. 292-1 1 Claim ABSTRACT OF THE DISCLOSURE A lock mounting to receive a lock set in a door stile having parallel usually upright side surfaces and a usually upright end surface merging with the side surfaces, the mounting including surfaces that can be characterized by the movement of a generatrix such as a right line always moving parallel to itself and normal to said side surfaces and travelling through said end surface to afford break-out edges, all of said surfaces together defining a socket to receive at least part of a lock set.
My invention relates to the environment of lock units, usually a door panel or door stile mounted to swing about the vertical axis of hinges which hold the-'door panel in a door frame with the meeting portions or door stile and door jamb slightly spaced apart. Lock units are mounted in the door panel in a number of different ways, yet there is always a need for improving the mounting of the door lock unit. In some instances a bore is provided through the material of the door panel from one side to the other at a distance spaced from the door edge face and another opening is bored from the edge face to intersect the first bore. A lock unit is then assembled within the two bores and interconnected for use. A certain precision is required for this operation.
It is therefore an object of my invention to provide a lock mounting in which the door panel is prepared in an improved fashion to receive a lock unit, especially a lock unit assembled prior to mounting on the door panel.
Another object of the invention is to provide a lock mounting in which the door panel is adapted to receive the lock mounting with little or no chance for error in configuration of the lock receiving portion and in which the amounts of skill and labor required are small.
Another object of the invention is in general to provide an improved lock mounting.
Other objects together with the foregoing are attained in the embodiments of the invention described in the accompanying description and illustrated in the accompanying drawings, in which:

A lock mounting of a somewhat related character is disclosed in my copending application entitled Lock Mounting filed Feb. 23, 1967 with Ser. No. 618,055 and assigned to the assignee hereof.
In this instance the lock mounting is particularly for use in a door panel 6 herein diagrammatically represented simply by a rectangular block. This is intended to show the immediate environment of a lock unit which is normally mounted on a door designed to swing about hinges with a vertical axis. The door or block has a pair of parallel, generally planar side faces 7 and 8 extending parallel to the hinge axis. The side faces merge with a planar edge face 9 extending vertically or parallel to the hinge axis and is approximately or exactly normal or perpendicular to the side faces 7 and 8. In some instances the edge face 9 is not exactly perpendicular to the side faces 7 and 8, being given a bevel or curvature, but it is nearly enough to a perpendicular relationship so that it is characterized herein as being substantially perpendicular.
Pursuant to the invention, the mounting in this instance is provided by removing material from the panel 6 (or in initially forming the panel 6 in the event it is molded or cast or is made up of deformable material) to provide a lock socket 11 defined by a surface 12 characterized by the movement of a generatrix always travelling parallel to itself and normal to the side surfaces 7 and 8. The movement of the generatrix can be considered as beginning at the edge face 9, travelling into and through the door panel 6 in a curved or arcuate path and then emerging or terminating at the edge surface 9. The path is such that the curved surface 12 breaks out or merges with the planar edge surface 9 to define break-out edges 13 and 14 parallel to each other. This configuration thus affords a mounting for a lock unit occupying the socket 11 with parts projecting therefrom on opposite sides of the surfaces 7 and 8 and with a projecting latch bolt merging between the break-out edges 13 and 14 to project in a direction normal to the edge surface 9. The mounting is characterized by a single defining surface extending from one side 7 to the other side 8 and breaking through the edge face 9.
In a somewhat related way the surface 7 in the mount of FIGURE 2 is interrupted by a channel 16 defined by generally parallel walls 17 and 18 generated by the movement of two generatrixes normal to the surface 7. Both of the surfaces or walls 17 and 18 emerge through the end face 19 of the material in break-out edges 21 and 22 as well as break-out edges 23 and 24. While the channel 16 is in some instances useful as it stands, it is normally altered by removal of material on the inside of the surface 18 so that the final result is very much like the socket of FIGURE 1 except that it does not extend entirely through the block but rather stops at a planar surface 26 parallel to the surface 7.
In FIGURE 3 the arrangement is comparable to that in FIGURE 1 in that the generatrix affords a curved surface 31 normal to the side surface 32 and having break-out edges 33 and 34. This form of device or mounting is usable as it stands for many forms of lock unit and the surface 31 is readily formed by various different sorts of tools.
FIGURE 4 is an arrangement comparable to FIGURE 3 in many regards and is also provided with a curved surface 36 generated by a line moving in a circular path always parallel to itself and normal to the side surface 37. In this instance the surface 36 does not extend entirely through the block, but rather terminates in a planar surface 38 parallel to the side surface 37, thus affording three break-out edges 39, 41 and 42. The curved surface 36 can be approximately a half circle in extent or even something more than that to afford a re-entrant pocket if desired.
In FIGURE the block is provided with surfaces 43 and 44 generated by movement of a right line parallel to itself and normal to the side surface 46 and is one which can be fabricated in a number of different ways. If a rotary tool is used, turning about its own axis parallel to the generatrix, and the diameter of the tool is quite small, the result approximates closely the surfaces indicated.
In FIGURE 6 the path of the generatrix is compound in that a first curved surface 51 affords a break-out edge 52 adjacent the end surface 53 of the block, and a second curved surface 54 affords a break-out edge 56 parallel to the break-out edge 52. The surfaces can be generated by a single generatrix moving in a compound circular path and afford an apex edge 57 where they merge.
In FIGURE 7 a similar arrangement is had in that curved opposite surfaces 61 and 62 are generated by the same generatrix operating in a circular path normal to the side surface 63 of the figure. This affords two breakout edges 64 and 66. Intersecting the arcuate surfaces 61 and 62 is a curved surface 67 which may be circular in configuration and is generated by a generatrix moving normal to the surface 63 but about another, parallel axis, so that two ridges 68 and 69 are afforded at the surface intersections.
In FIGURE 8 a configuration similar to that of FIG- URE 7 is afforded except that the opposite surfaces 71 and 72, as well as the surface 73 which intersects them, do not extend entirely through the block, but rather end at a planar surface 74 parallel to the side surface 76.
In FIGURE 9 there is disclosed an arrangement in which a circular cylindrical surface 81 extends entirely through the block 82 from one side face 83 to the parallel side face 84 thereof. The axis of the surface 81 is substantially normal to the surface 83. An intersecting surface 86 and an opposite intersecting surface 87 can be generated by the same generatrix normal to the surface 83 and moving about an axis spaced from the axis of the opening 81. The surfaces 86 and 87 do not extend through either side surface of the block, although they do intersect the edge face 88 thereof to provide break-out edges 89, 91, 92 and 93. In addition, where the various surfaces intersect, ridges 94 and 96 result.
In FIGURE there is disclosed an arrangement in which a'block 97 having side faces 98 and 99 is contoured by means of a rotary cutter 101 moving about an axis at the center of a shaft 102 and advancing in the direction of the arrow 103. There results a surface 104 which can be described by the rectilinear movement of a generatrix into the material 98 from one edge face 106 thereof for a sufficient distance to determine not only break-out edges 107 and 108, but also generally parallel side edges 109 and 111 and a curved end surface 112.
In FIGURE 11 there is disclosed an arrangement very much as in the'preceding figures in which a block 116 such as the stile of a door and having parallel opposite faces 117 and 118 is characterized by a surface 121 as generated by a generatrix moving normal to the side face 117, for example, and moving inwardly from the edge face 122 to leave a breakout edge 123 and emerging to leave another break-out edge 124 parallel to the first edge 123 and normal to the plane of the surface 117. As an illustration, a lock mechanism 126 is mounted in the stile and occupies the space which has been provided for it and meets the material of the stile along the surface 121 between the break-out edges 123 and 124, for example.
