Detailed Description In the installation of locksets in door panels for cooperation with strikes in related door frames, it is often necessary to provide any one of several difrerent backsets.
The backset is usually understood tG be the horizontal dis-tance between the edge of the door panel and the axis of rota-tion of the knob or other actuating devicev For various reasons, some mechanical, some architectural, and some simplv matters of choi~e, it is customary to afford a backset of any one of several differen~ amounts at the initial installation.
This custom involves tne manufacture and stocking o locksets;
2articularly, latch bolts, having different dimensions to acco~modate the ~arious desirable backset choices.
It is there ore an object of the inYention to provide a sim?lified arrange~ent in which a lockset can be manufactured easily as one backset dimension or another backset dimensionO
Another obje~t of the invention is to provide an arrange-ment for a bolt construction that can easily be changed in the field to afford any one of several different backset lengths.
A further object of the invention is to provide an inter-changea~le length of bolt unit, easily manufactured and eco~
no~ical to stock and that can readily be assembled in an appro2riate fashion for the desired installation.
Another object of the invention is to provide a bolt con-struction that can be changed in length by an ordinary workmanand without requiring any but the most elementary tools.
A further object of the invention is to provide a bolt unit that can be assembled with any of several chosen lengths and when assembled operates as reliably and satisfactorily as a non-variable unit.
A further object i5 in general to afford an improved latch bolt unit.
Inasmuch as the general environment and operation of the lock unit are completely standard, they are not disclosed in detail herein, the disclosure being on that portion of the -~ ~3~
structure t'nat can readily be varied to provide any one of several different backset lengths or dimensions. Under these circumstances, there is normally provided a circular, cylin-drical housin~ 6 to be mounted in a recess in a door panel.
The housing is interrelated with a mounting plate 7 and a housing plate 8 normally joined together to receive fasteners for holding the unit in the door panel. The housing 6 is preferab~y a one-piece, flanged construction that has a circular, cylindrical side wall 9 and also has a planar or `10 flat end wall 11 with an aperture 12 therein.
~ ounted to reciprocate in the housing 6 is a standard bolt 13. In this case, the bolt is a latch bolt having an engaging strap 14 thereon and provided with spring means (not shown) for urgins the latch bolt into normally projected posi-1~ ~ion. The openlng 12 is particularly of a rectangular con-figuration having side walls 16 and 17 that are parallel to each other.
In accordance with the invention there is provided a pair of side plates 18 and 19 r particularly to interengage with the housing 6. The side plates are preferably identical (bearing different reference numerals herein only for conveni-ence), and each is preferably formed from an originally planar metal plate. Each side plate has an angle hook 21 at one end of a dimension to pass readily through the opening 12 and then to be shifted laterally until the outside surface of the side plate abuts the adjacent edge 16 or 17 of the aperture with the angle hook 21 overlapping and lying immediately against the inside surface of the end wall 11.
Each side ~late within i_s width has one or more s~acers 2 75~
and 23 extending transversely therefrom and of substantially the same length. The spacer ends lie in abutment with the other side plate and maintain a set minimum distance between the~. Fur.hermore, each of the side plates at one end has a lug 26 disposed on one side of the centerline of the side plate and has an aperture 27 therein. A tab 28 on another lug on the other side of the centerline, and bent at a right angle ~rom the side plate, has a shoulder thereon at the same distance from the side plate as the spacers 22 and 23.
The net result of this construction is that the tabs 28 are offset vertically sufficiently so that the tab on one side plate enters into the aperture in the lug 26 of the other side plate and maintains the parallelism of the plates just as the spacers 22 and 23 do. After the tabs have been inserted in _heir respective lug apertures, the tabs 28 are twisted slightly by a tool such as a pair of pliers so that the lugs are held against shoulders on the tabs, and the entire side plate assembly is permanently and rigidly secured with respect to ,he housing 6.
The side plates 18 and 19 serve as a mounting for actuat~
ing structure. Rach of the side plates has an embossment 31 therein surrounding an aperture 32 therethrou~h designed to receive a cross-shaft 33 or other actuator for the latch bolt.
Preferably connected to the actuator 33 by appropriate inter-~5 vening mechanism (not shown in detail), there is a hook 34 moving in a longitudinal direction upon rotation of the shaft 33. The hook is releasably engaged with the cross-shaft 33 and is also engaged with a lug 36 projecting laterally from the bolt 13. When the shaft 33 is rotated in either direction, the hoo~ 34 is retracted and correspondinglv retracts the 5~
l~tc'l bol t 13 .
Since it is particularly desired to af~ord different bac~:set dimensions, ~he side plates lB and 19, as sho~m in Figures 4 and 5, have a predetermined minim~n dimension for t..e length and a corresponding minimum di~ension _or the dis.ance between the angle hook 21 used therewith and the center of the aperture 32 or the embossment 31.
A different len~th side plate 41, as shown in Figures 6 all~ 7, i~ ~ovided. The construction is identical with that of the side plate 19, except that the length is greater and the location of the embossment 31 around the aperture 32 like-ise is ~artller fxom the angle hook 21. The associatecl hool~ 34 is correspondin~ly longer. Upon initial assembly, the as e~bler can elect to utilize either a short side plate 1~ c- a lon~ side plate 41 in order to afford a finis~ed latch unit having the desired backset.
.r~n ir.iti-l~ ].~7 asse~nb]ed latch unit; ~or example, with a short side plat:e 19, can be disassembled by releasing the holers 2~, unhooking the side plates from the housing 6 and reassembli~g the structure with longer side plates 41, m~king the necessary rotation of the tab ends. During the course of such side pl~te change, the initial short hook s replaced with a lcnger hook hav~ng the proper dimension for the longer side plates. The net result is to provide a different backset
