Abstract
Abstract A concealed cam lock and keeper both of which can be mounted within cavities in the check rails of the respective lower and upper sash of a double hung window.
The concealed cam lock has only an exposed handle with a raised section of the housing closing off a notch required for assembly of the housing with the check rail. The handle of the check rail lock has an offset to cover any wood splintering that may have occurred in the check rail of the lower sash in forming the check rail for receiving the housing of the check rail lock. The keeper is mountable in a cavity in the check rail of the upper sash at a location to permit mounting of weather stripping therebeneath and generally at the level of the lower edge of the window glazing and has downwardly inclined openings to receive fasteners for attaching the keeper to the check rail and which can extend into the check rail without interference with the glazing.

CONCEAIED CH~CK RAIL LOCK P.ND KEEPER
Background of the Inventlon This ~nvention pertai.ns to a check rail lock and keeper w~ich except for the ~perating handle can be 5 completely concealed within the check rail~ ~ the upper and lower sash ~f a d~ubl~ hung window. Each of the check rails : is p.rovided wlth a cavity with the cavity ln the check rall of the lower ~ash receiving and enclosing a check rail lock h~usin~ having an ~laxposed ~ace and which rc)tatably m~unts a 10 lockin~ ca~ ~perable by a rotatable shaft extending upwardly from the h~using and having a handle at a level above the check rail a~sociated with the rotatable ~haft. A keeper is positioned in and ~nclosed in a cavity in the check rail of the upper ~ash at a location ~o pennit tlle mounting of 15 weather 6tripping and has downwardly inclilled openings extendi~g fxom the front face there~f enabling the insertion of fastening member~ into the check rail without inter~ering with window glazing. O~her improvemen~s and refinements are described h~rei~after.
The concealea check rail lock has a number of components known in prior art structures and particularly as shown in my copending application Serial No. 521,960 filed October 31, 1986. The prior check rail lock has a housing mountable to the top of check rail and which mounts a 25 rotatable shaft having a locking cam disposed internally :~ of the housing and a handle secured to the shaft 33LO~ Case 85 ~xternally of the housing. A locking c:am i~ rotatable between locked ~nd unlocked po~itions as determined by limit ~;tops within the hou~ing and a ~;pring detent washer detents the lo~king s;:a~ in either of thesP position~. A coacting keeper interengages wi~h ~he locking cam iII a locked position .

Summary of the Invention A primary ~eature of the invention is to ~?rovide a new and impro~ed concealed check rail locX and keeper ha~ing comp~nents in~ertable in c~vities in the check rails of the upper and lower sa~h of a double hung window with one oompon~nt being a houslng having a rotatable locking cam dispDs~d internally thereof and with a rotatable ~haft mounting the l~cking cam and having only a handl~ ~ecured to the shaft which is exposed to ~i~w. Another camponent is a keeper which is mountable in a cavity in the check rail ~f the upper 6ash with only an exp~sed front face and with dow~wardly lnclined ~peninqs ~r receiving fas~eners which . can exte~d d~wnwardly into the upper sash check rail with~ut : 20 inter~erence with window glazing. The keeper can be at tbe : level of the lower edge ~f the window glazing while still being located at a distance ~rom the lower edge of the upper sash check rail to permit the mounting o~ weather stripping.
~ore particul~rly, the concealed check rail lock ; 25 has a housing with a rotata~le ~haft extending upwardly therefrom and a locking cam within the hou6ing 6ecured to the shaft. A handle i~ ~cured to the upper end of the sha~t at a di~tance from the hou~ing. The housing can be ~ount~d in ~ cavity of the check rail of the lower ~a~h of a double hung window and have an exposed face. The check rail has a notch above the cavity to permit assembly with the part of the shaft above the housing positioned in the notch and a raised sec-tion of the housing its within the remainder of the notch to CQact with the upper surface of the check rail to form a smooth continuous surface. The keeper fits within a cavity in the check rail of the upper sash of the double hung window to have only an exposed face. The keeper is at the level of the lower part of the window ylazing and above the lower edge of the check rail to permit mounting of weather stripping mat~rial. The keeper has at least a pair of openings extending to the face of the keeper which are downwardly inclined to permit the insertion of fasteners into the check rail without interfering with the glazing.
Additionally, the handle has a generally frusto-conical section at the upper end of the sha~t and with an offset which overlies the notch and a portion of the check rail of the upper sash when the handle is in locked position and which moves to a position ou-t of overlapped relation with the upper sash check rail when the lock is in an opened positlon.
Accordingly the invention seeks to provide a new and improved concealed check rail lock and keeper having a housing and a keeper which can both be enclosed within cavities formed in the check rails of the sash of a double hung window with only an operating handle exposed.
The invention in one broad aspect provides a check rail lock arranged for concealed mounting in a double hung window lower sash check rail defining a front face and a top face and having a cavity opening through the-front face and ' ~, 8~
top face thereof. The check rail lock comprises a housing defining a top wall, a front face, and a raised portion adjacent the front face and defining a top surface, with a shaft rotatably mounted in the housing and extendin~
outwardly from the top wall thereof. A locking cam in the housing is ~ixed to the shaft, and a handle is fixed to said outer end of the shaft to be disposed at a greater distance from the top wall than -Erom the top surface of the raised portion and only partially overlying the raised portion in one position thereof. Thus the housing, shaftl and raised portion can be inserted through the check rail front face into the cavity thereof, with the raised portion top surface flush with the top face of the check rail. The check rail lock is arran~ed so that the handle is the only element of the check rail lock which is disposed above the top surface of the check rail when the check rail lock is mounted in the check rail cavity.
Preferably a keeper is adapted to be mounted in a cavity in the upper sash check, and inclined openings in the keeper are provided for directing fasteners extended therethrough downwardly as a result of mounting the keeper to the upper sash check rail.
Another aspect of the invention provides a window sash structure comprising a lower sash having a check rail defining a front face and a top face and having a cavity opening continuously through the front face and top face thereof, and a check rail lock comprising a housing having a top wall and a front portion provided with an upstanding closure wall. A shaft is rotatably mounted in the housing and extends upwardly thererom rearwardly of the closure "
wall, the shaft defining an upper end disposed above the top face of the check rail. A locking cam in the housing is fixed to the shaft, and a handle is fixed to the upper end of the shaft and partially overlies the closure wall in one position thereof whereby the housing, shaft and closure wall can be inserted through the sash front face into the cavity, the closure wall defining a top surEace flush with the top face of the check rail and fully closing the cavity outwardly of the handle at said top face of the check rail.
Preferably the window sash structure includes an upper sash having a check rail and defining a rear face confronting the front face of the lower sash check rail when the check rails are juxtaposed, the upper sash check rail having a cavity opening through the rear face. A ]ceeper is in the cavity of the upper check rail and downardly inclined fasteners ex-tend through the keeper into the upper check rail.
Other aspects and features of the invention will become apparent from the following detailed description of a preferred embodiment of the invention.
