No. 801,048 7 Claims. (Cl. 292-357) contact with the face of a door without increasing the diameter beyond that now commonly employed.
Another object of this invention is to provide the lock mounting plate with a series of raised peripheral lugs for the purpose of engaging with and securing the rose, thereby eliminating the necessity for spring wire clips or similar devices normally used for this purpose.
Another object of this invention is to provide a lock mounting plate to which a rose escutcheon can be applied and secured without regard to its rotative or circular orientation.
A further object of this invention is to provide a mounting plate having a series of spaced apart lugs with which the rose escutcheon interlocks and which secure the rose escutcheon from removal and having other means to limit rotation of the rose escutcheon.
The invention is shown by way of illustration in th accompanying drawings in which FIG. 1 is a horizontal section of a door showing the position of the mounting plate and the snap-on type rose escutcheon when a lock set is applied to a door.
FIG. 2 is a similar section showing a common type of clamping plate in which one edge has been forced into the bored hole.
FIG. 3 is a face view of the clamping plate forming the subject matter of the present invention.
FIG. 4 is a cross section taken on line IV-IV FIG. 3.
FIG. 5 is a cross section of the snap-on type rose plate.
FIG. 6 is a rear view thereof looking in the direction of arrows a.
FIG. 7 is an enlarged section on line 77 FIG. 5 of one of the detents.
FIG; 8 is a diagrammatic view of the two holes bored inaccurately in a door, and
FIG. 9 is a face view of the common type of clamping plate shown in FIG. 2.
Several types of latch sets and lock sets, especially of the cylindrical and tubular types require a mounting plate A on one or both faces of a door, see FIG. 1, and two screws BB to secure the mounting plate and latch set in place when installed in a door, and in addition thereto a rose escutcheon C is provided to cover the mounting plate and the screws.
. In preparing a door for installation of a latch set of the type referred to, two holes are bored in the door, one large hole D through the opposite faces of the door and the other and smaller hole E through the edge of the door: the smaller hole receives the latch bolt unit F and the larger hole the latch bolt actuating unit G. In boring the smaller hole, its center line should intersect and be perpendicular to the center line of the larger hole, and correct alignment is insured if a boring jig is used, but in many instances an ordinary brace and bit is employed, without a jig or other installation aid, and in that case, if the carpenter or other mechanic employed is not careful, the center line of the smaller hole may be a sixteenth of an "ice inch or more either above or below the center line of the larger hole, or the large hole may be bored too close to or too far away from the edge of the door. Thus, when the latch bolt unit and latch bolt actuating unit are installed and interlocked, the latch bolt actuating unit must assume a position slightly eccentric to the large hole in order to align with the latch bolt unit and to function properly. Under these conditions the clamping plate must also assume a slightly eccentric position with relation to the large hole as the screws passing through the clamping plate must align with threaded lugs or posts forming part of the latch bolt actuating unit.
FIGS. 2 and 9 show an ordinary or common form of mounting plate. It consists of a flat circular plate 2 having a central bearing hub 3 and an upraised peripheral annular flange 4 which is provided for the purpose of engaging with and securing the snap-on rose escutcheon. A mounting plate so constructed does not permit much shifting one way or another to conform to the eccentric position which the latch bolt actuating un-it assumes with relation to the hole bored through the face of the door, if the bored holes have been improperly drilled, as the upraised outer edge or flange of the mounting plate forms a shoulder 5 which is forced into or drops into the larger hole as shown in FIG. 2 when the screws are tightened, thus assuming an angle with relation to the face of the door and making it diflicult to align the clamping screws, and furthermore making it almost impossible to apply the snap-on rose escutcheon inasmuch as a portion of the annular flange no longer is upraised to receive the rose escutcheon.
The subject matter of the present invention is a mounting plate and a snap-on rose escutcheon which has none of the faults or disadvantages heretofore referred to. The clamping plate is best shown in FIGS. 1, 3 and 4. The mounting plate is circular in form and presents a flat surface with the exception of a central bearing hub 10 and an annular raised portion 6 which is formed to stifien. the plate and to prevent bending or dishing when the screws passing through the holes 6 and 6 are tightened. The outer marginal portion 8 and the surface 9 in which the bearing hub 10 is formed are the flat portions of the plate, and 6 the raised portion or strengthening rib. Formed in the outer margin 8 of the plate or disc is a plurality of uniformly spaced lugs 11. The lugs are raised with relation to the flat surfaces 8 and 9 and extend slightly beyond the peripheral edge of the plate. They are formed to engage with and secure the snap-on rose escutcheon.
. 14 formed therein.
The rose is best shown in FIGS. 5, 6 and 7. The rose escutcheon may have any shape or contour desired, but it must have an annular flange 12 formed at its peripheral edge. This flange has a plurality of latch-shaped detents The detents shown in FIG. 6 are uniformly spaced, and the spacing between them is approximately one half of the spacing between the lugs 11. There may be as many detents as desired, but in this instance three detents are formed in the flange at one side thereof and diametrically opposite are formed four detents. This is sufficient as no matter how the rose escutcheon is turned when it is to be applied, one of the three detents will align and snap over one of the lugs 11, and two of the four detents will snap over other lugs, thus securely retaining the rose escutcheon when snapped on. Although the lugs and detents have been shown uniformly spaced, the same result can be obtained by properly spacing them in a non-uniform manner. It should also be noted, see FIG. 7, that each detent is provided with a lead-in edge 15 to facilitate the start of the snap-on action.
To accommodate certain types of locks the larger hole or bore through the opposite faces of the door is two and one-eighth inches in diameter and the mounting plate is two and onehalf inches in diameter. This makes it possible to shift the mounting plate as much as three-sixteenths of an inch in any direction with relation to the center of the larger hole Without uncovering any portion thereof. Provision is made on the mounting plate to accommodate this shift because the flat surfaces 8 in FIG. 3 are extended outwardly between the lugs 11 to overlie the hole bored in the door face. It should be noted that the extensions of the flat surfaces 8 which are extended between the lugs 11 present a diameter very slightly less than the outside diameter of the lugs 11. This clearance is important as the flat surfaces 8 would otherwise interfere with the proper snap-on action of the rose detents, particularly if a portion of a detent overlies the extended flat surface 8 between the lugs. If the smaller hole bored through the edge of the door is incorrectly bored, such a shift of the mounting plate can be made without any portion thereof entering the larger hole and assuming a cocked or angular position such as shown in FIG. 2. Furthermore, the lugs 11 are raised with relation to the surface of the mounting plate and are the only part of the plate engaged by the detents of the rose escutcheon. Thus there will always be suflicient space between the face of the door and the lugs to receive and secure the detents in the rose escutcheon. By referring to FIG. 5, it will be noted that a slot 16 is formed in the edge of the flange 12 between the four detents 14. This slot is employed to receive the blade of a screwdriver by means of which the rose escutcheon can be readily pried ofl.
