Abstract:
A locking paddle handle assembly for closures has a housing with a paddle handle pivotally mounted therein, a latch which latches and unlatches the closure upon rotation of the paddle handle, and an exterior key lock with a movable member that shifts between locked and unlocked positions. A deadbolt lock selectively engages the closure frame in the locked position to positively retain the closure closed. The deadbolt lock is operably connected with the movable key lock member, such that movement of the latter between the latched and unlatched positions contemporaneously shifts the deadbolt lock between the locked and unlocked positions. A remotely operable controller may be mounted either horizontally or vertically relative the handle assembly and is operably connected to a multi-armed lock cam to power shift the deadbolt lock between the locked and unlocked positions from a remote location.

     BACKGROUND OF THE INVENTION 
     The present invention relates to latches for movable closures and the like, and, in particular, to a remotely operated locking paddle handle latch assembly. 
     Paddle handles are generally well known in the art, and are typically flush mounted on an associated closure or door to facilitate selectively shifting the closure between an open unlatched position and closed latched position. Paddle handle assemblies are used widely on entry doors for recreational vehicles, motor homes and the like, and in such applications, require that the latch mechanism be accessible and operable from both the inside and the outside of the vehicle, and that they include a deadbolt lock for maximum security. 
     Heretofore, paddle handle assemblies have proven generally effective, although they experience certain drawbacks. For example, such prior art paddle handle assemblies are not particularly adapted for use with remotely operated power actuators, which have become quite popular in the recreational vehicle industry. Hence, a paddle handle assembly which overcomes such drawbacks would be advantageous. 
     SUMMARY OF THE INVENTION 
     One aspect of the present invention is a remotely operated locking paddle handle assembly for closures and the like having a housing adapted for mounting in or adjacent an associated closure of the type that can be shifted between an open position and a closed position. A paddle handle is pivotally mounted in an interior portion of the housing for rotation between a retracted position and an extended position. A latch is operably connected with the paddle handle, and configured such that when the paddle handle is in the retracted position, the latch is in the latched position, wherein the closure cannot be unintentionally shifted from the closed position, and when the paddle handle is in the extended position, the latch is in an unlatched position, wherein the closure is free to be shifted from the closed position to the open position. A key lock is mounted on an exterior portion of the housing, and includes a movable key lock member that is selectively moveable between a locked position and an unlocked position. A deadbolt lock is movably mounted in the housing for shifting between a locked position, wherein the closure is positively retained in the closed position, and an unlocked position, wherein the closure is free to be shifted between the open position and closed position. The deadbolt lock is operably connected with the movable key lock member, whereby movement of the movable key lock member between the locked and unlocked positions shifts the deadbolt lock between the locked and unlocked positions. A remotely operated controller is operably connected with the deadbolt lock through a multi-arm lock cam having a first crank arm operably connected with the deadbolt lock and second and third crank arms. The multi-arm lock cam is rotatably mounted in the housing and operably connected with the key lock member for rotation therewith. The remotely operable controller, which may be mounted horizontally or vertically via either of the second or third crank arms relative and proximate the remotely operated locking paddle handle latch assembly, shifts the deadbolt lock between the locked and unlocked positions from a remote location when activated. 
     Another aspect of the present invention is a remotely operated paddle handle assembly that has an uncomplicated design which is efficient in use, economical to manufacture, capable of a long operating life, and particularly well adapted for the proposed use. 
     A further aspect of the present invention is a remotely operated locking paddle handle latch assembly that is adapted for a variety of mounting configurations and applications. 
     These and other advantages of the invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims, and appended drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in  FIG. 1 . However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
     The reference numeral  1  ( FIGS. 1-4 ) generally designates a remotely operated locking paddle handle latch assembly embodying the present invention. Locking paddle handle latch assembly  1  includes a housing  2  adapted for mounting in or adjacent to an associated closure of the type that can be shifted between an open position and a closed position. A paddle handle  4  is pivotally mounted in an interior portion of housing  2  for rotation between a retracted position and an extended position. A latch  5  is operably connected with paddle handle  4 , and configured such that when paddle handle  4  is in the retracted position, latch  5  is in a latched position, wherein the closure cannot be unintentionally shifted from the closed position, and such that when paddle handle  4  is in the extended position, latch  5  is in an unlatched position, wherein the closure is free to be shifted from the closed position to the open position. A key lock  6  is mounted on an exterior portion of housing  2 , and includes a movable key lock member  7  that is selectively movable between a locked position and an unlocked position. A deadbolt lock  9  is mounted in housing  2  for shifting between a locked position, wherein the closure is positively retained in the closed position, and an unlocked position, wherein the closure is free to be shifted between the open and closed positions. Deadbolt lock  9  is operably connected with movable key lock member  7 , such that movement of the movable key lock member  7  between the locked and unlocked positions shifts the deadbolt lock  9  between the locked and unlocked positions. A remotely operated controller  11  ( FIGS. 11 and 12 ) reciprocates between locked and unlocked positions, and is operably connected with deadbolt lock  9  to shift the same between the locked and unlocked positions from a remote location. 
     As best illustrated in  FIGS. 1-5 , the illustrated housing  2  has a two-part construction, comprising an exterior plate  22  in which paddle handle  4  is pivotally mounted, and an interior plate  23  which mounts on the interior of the closure and is attached to exterior plate  22  by fasteners. The illustrated exterior plate  22  includes a centrally disposed, bowl-shaped recess  24  located directly behind paddle handle  4  which provides finger access to facilitate rotation of paddle handle  4  between the retracted and extended positions. The bottom wall of recess  24  includes an actuator window through which an actuator tab on paddle handle  4  extends to operate latch  5 . The marginal portion of exterior plate  22  includes a lock aperture  27  in which key lock  6  is mounted. 
     The inside surface of exterior plate  22  includes a cylindrically-shaped lock boss  34  ( FIG. 4 ), the interior of which defines lock aperture  27 . The interior plate  23  of housing  2  includes a marginal portion  40  ( FIG. 2 ) which engages the interior surface of the closure, as well as fastener bosses  41  ( FIG. 2 ) and a lock boss  42  ( FIG. 5 ). The rearwardmost or interior side edge  48  of interior plate  23  is contoured to define a stationary interior handle  49 , which facilitates opening and closing the closure from the interior portion of the vehicle. A release lever  50  is pivotally mounted on the interior surface of interior plate  23 . Release lever  50  includes a forwardly protruding actuator tab which extends through to the latch  5  to selectively shift the same to the unlatched position. An interior lock knob  52  is pivotally received in lock boss  42  on the interior plate  23 , and is operably connected with the deadbolt lock  9  as described below. 
     In the illustrated example, the moveable key lock member  7  is in the form of a cylindrical lock plug which is received in the lock aperture  27  on the exterior housing plate  22 , and is rotatably mounted in lock boss  34  for rotation between locked and unlocked positions. A multi-arm deadbolt lock cam  74  is pivotally mounted in the interior end of lock boss  34 , and is operably connected with key lock member  7  for rotation therewith. The illustrated deadbolt lock cam  74  has a first crank arm  76  that is operably connected with deadbolt lock  9 . As best illustrated in  FIGS. 7-10 , deadbolt lock cam  74  has a cylindrically-shaped base  77  with a recessed end oriented toward exterior housing plate  22  and a faced shaft  78  oriented toward interior housing plate  23 . The shaft  78  on deadbolt lock cam  74  extends through the lock boss  42  in the interior housing plate  23 , and the lock knob  52  is mounted on the interior end thereof, such that rotation of lock knob  52  from the interior of the vehicle rotates deadbolt lock cam  74  between the locked and unlocked positions, and simultaneously shifts the deadbolt lock  9  between the locked and unlocked positions. 
     The illustrated deadbolt lock  9  includes a deadbolt  80  ( FIG. 12 ) slidably mounted in the exterior housing plate  22 , and includes an outer end which extends exterior of housing  2  for engagement with an associated strike bolt assembly, and an inner end which extends interior of housing  2 . A link  83  has a first end  84  thereof pivotally connected with the inner end  82  of deadbolt  80 , and a second end  85  thereof pivotally connected with the first crank arm  76  of lock cam  74 , such that rotation of key lock member  7  between the locked and unlocked positions longitudinally shifts the deadbolt  80  between the locked and unlocked positions. 
     The multi-arm lock cam  74  also includes a second crank arm  130 , which is adapted for operable connection with remotely operable controller  11 , which rotates lock cam  74 , and shifts the deadbolt lock  80  between the locked and unlocked positions. More specifically, crank arm  130  includes an aperture  131  adjacent its outer end into which an actuator rod  133  is received, which is operably connected with remotely operable controller  11 , which is typically mounted in the vehicle door. In the illustrated example, remotely operated controller  11  includes a linear actuating device in the form of a solenoid  15  or the like, which has a plunger portion  13  that shifts or reciprocates longitudinally between locked and unlocked positions in response to a remotely generated signal. The illustrated remotely operable controller  11  also includes a signal receiver portion  12  which actuates the motor upon detection of an appropriate radio frequency signal or the like. Remote actuation of the controller  11  longitudinally shifts the actuator rod  133 , which in turn rotates deadbolt lock cam  74  and shifts deadbolt  80  between the locked and unlocked positions. 
     The reference numeral  74   a  generally designates an alternative embodiment of the deadbolt lock cam having a third crank arm to accommodate both vertical and horizontal actuation. Since deadbolt lock cam  74   a  is similar to the previously described deadbolt lock cam  74 , similar parts appearing in  FIGS. 1-12  and  13 - 22  are represented by the same, corresponding reference numerals, except for the suffix “a” in the numerals of the latter. With reference to  FIG. 12 , the panel handle latch assembly  1  is designed to be used for only horizontal actuation, and includes only two crank arms  76  and  130  respectively. In contrast, the multi-arm deadbolt lock cam  74   a  ( FIGS. 13-21 ) includes a third crank arm  160  which facilitates both horizontal and vertical actuation of the associated panel handle latch assembly, as shown in  FIG. 22 . More specifically, with reference to  FIGS. 13-22 , the third crank arm  160  is also adapted for operable connection with the remotely operable controller  11   a , which rotates lock cam  74   a , and shifts the deadbolt lock  80   a  between the locked and unlocked positions. 
     Crank arm  160  includes an aperture  161  adjacent its outer end into which an actuator rod  133   a  is received, which is operably connected with remotely operable controller  11   a , which is typically mounted in the vehicle door. Crank arm  160  is located circumferentially between the first and second crank arms  76   a  and  130   a , and permits the remotely operated controller  11   a  to be oriented in a generally vertical direction, as best illustrated in the lower portion of  FIG. 22 . The lock cam  74   a  also permits the remotely operated controller  11   a  to be oriented in a generally horizontal direction, as best illustrated in the upper portion of  FIG. 22 , by using crank arm  130   a  in the manner described above. In the illustrated example, the third crank arm  160  is disposed approximately 120 to 130 degrees from the first crank arm  76   a  and approximately 60 degrees from the second crank arm  130   a . Remote actuation of the controller  11   a  longitudinally shifts the actuator rod  133   a , which in turn rotates deadbolt lock cam  74   a  and shifts deadbolt  80   a  between the locked and unlocked positions. 
     In the foregoing description, it will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concepts disclosed herein. Such modifications are to be considered as included in the following claims, unless these claims by their language expressly state otherwise.
