Operation of the mechanical linkage causes the operating mechanism to operate.
Description




TECHNICAL FIELD




This invention relates to handles used on vehicles and structures. More particularly this invention relates to a paddle handle assembly that has an offset operating mechanism to effect a slim profile in order to conserve space in or on the object to which the paddle handle assembly is attached.




BACKGROUND




Handle assemblies utilizing paddle handles are well known in industry for use on vehicle doors or compartments. Additionally, paddle handles are commonly used in homes or businesses in a variety of applications. Typically, the paddle handle includes a tray which has a recess. The paddle handle is disposed inside of this tray and is pivotal with respect to this tray. The tray is mounted flush with the surface of the door being latched. This flush mounting provides aerodynamic benefits, and is attractive in style and appearance.




Connected to the paddle handle, in back of the tray, is a linkage or an operating arm which actuates once the paddle handle is rotated by a person or a machine. Such linkages or operating arms are then connected to a cable, rod, or other such mechanism, which in turn is connected to a door latch. Upon actuation of the linkage, the door is unlatched and may be opened. Alternatively, the linkages or operating arms are sometimes themselves equipped with a latch bar which is fit into an opening in a door jamb or contacts another surface. Actuation of the operating arm causes the latch bar to move out of the door jamb or away from the other surface, hence allowing the door to be opened.




Different configurations of operating arms and paddle handles in general are well known in the prior art. Various configurations of operating arms and paddle handles are described in U.S. Pat. Nos. 4,420,954; 4,892,338; and 4,951,486. In addition, another such paddle handle that represents the prior art is a rotary combination compartment lock sold by Hansen International of Columbia, S.C.




While the prior art teaches various configurations of operating arms for paddle handles, the prior art does not teach a way of configuring a paddle handle such that the width of the paddle handle assembly is minimized. The prior art places the operating arm or linkage directly behind the recess formed in the tray. This placement causes the paddle handle assembly to have a significant depth. In applications such as in vehicle doors, space is at a premium, and it may not be possible to fit a paddle handle into a door that is thin or has other components. Therefore, there is a need for an offset handle assembly which has a slim profile thereby minimizing the depth of the paddle handle and allowing the paddle handle to be used in applications which require a paddle handle assembly of small depth.




SUMMARY




Objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.




One aspect of the present invention provides an improved paddle handle assembly having an offset operating mechanism. The paddle handle assembly consists of a tray which has a front side and a back side. The tray also has a recess and a paddle handle is disposed in this recess on the front side of the tray. The paddle handle can be pivoted with respect to the tray. Also, the paddle handle assembly has a base member that extends to the back side of the tray. This base member has a flange on one end. The base flange extends laterally adjacent the recess. Further, a drive member is included in the paddle handle assembly. The drive member has a drive portion that is disposed on the back side of the tray. The drive member is mounted for pivotal movement with the paddle handle. At least one linkage member is operatively connected to the drive member. The linkage member is disposed on the back side of the tray. Also, an operating mechanism is present in the paddle handle assembly. This operating mechanism is secured to the base member flange. The operating mechanism is operatively connected to the linkage member. Pivoting of the paddle handle with respect to the tray causes the drive member and the linkage member to effect operation of the operating mechanism.




Also, according to another aspect of the invention, an offset handle assembly is provided. This assembly has a tray which has both a front side and a back side, and also defines a recess. A handle which is pivotal with respect to the tray is provided. This handle is substantially located within the recess on the front side of the tray. A mechanical linkage is operatively connected to this handle, and the mechanical linkage operates when the handle is turned. An operating mechanism is operatively connected to this mechanical linkage. The operating mechanism is disposed on the back side of the tray and is adjacent to the recess so as to be laterally offset from the handle. Operation of the mechanical linkage causes the operating mechanism to operate.




Optionally, the operating mechanism of the assembly may include a pin and a first operating mechanism member rotatably mounted to the pin. A second operating mechanism member may be rotatably mounted to the pin. The second operating mechanism member is pivotable with respect to the first operating mechanism member. An operating mechanism bolt may extend through the first and second operating mechanism members for pivoting the first operating mechanism member relative to the second operating mechanism member.




Alternatively, the paddle handle assembly may have a first rod that could pivotally connect to one end of the operating mechanism for connection to a first latch. A second rod could pivotally connect to another end of the operating mechanism in order to connect to a second latch.




Another aspect of the present invention may have the linkage member move substantially forward and backward in one direction. The assembly may further include a first rod that is pivotally connected to one end of the operating mechanism. The first rod may move in a direction substantially perpendicular to that of the linkage member. A second rod may be pivotally connected to one end of the operating mechanism. The second rod may move in a direction substantially perpendicular to that of the linkage member.

DETAILED DESCRIPTION




Reference will now be made to the presently preferred embodiment of the present invention, an example of which is illustrated in the drawings. The example is provided by way of explanation of the invention and is not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment can be used on another embodiment to yield yet a third embodiment. Accordingly, it is intended that the present invention include such modifications and variations.




Referring now to the drawings,

FIG. 1

shows one example of an offset handle assembly


10


in accordance with certain aspects of the present invention. Offset handle assembly


10


has an operating mechanism


26


laterally offset from a tray


11


. Laterally offsetting operating mechanism


26


from tray


11


allows the offset handle assembly


10


to have a slim profile.





FIG. 2

shows a front isometric view of offset handle assembly


10


. Tray


11


has a tray flange


13


extending about its perimeter. Tray


11


also has a recess


12


located substantially in the center of tray


11


. Recess


12


has a paddle handle


14


disposed therein. Paddle handle


14


is pivotal with respect to tray


11


about a pin


38


. Tray


11


has a front side


42


and a back side


41


. Offset handle assembly


10


has a base member


16


attached to the back side


41


of tray


11


. This attachment is effectuated by tray bolts


36


and tray nuts


37


, however, it is to be understood that the attachment of base member


16


to tray


11


can be accomplished by various means known in the prior art such as, pinning, riveting, or welding. Alternately, it is possible that base member


16


be formed integral with tray


11


.




As shown, base member


16


has a base flange


17


extending from one end. Preferably base member


16


and base flange


17


are formed from one piece. However, it is also possible to weld or otherwise attach base flange


17


to base member


16


.




Pin


38


pivotally connects a drive member


19


to tray


11


. A clip


52


engages pin


38


. Drive member


19


has a drive portion


43


attached to the back side


41


of tray


11


. A first spring


20


is contiguous with drive portion


43


and is also in contact with drive member


19


. First spring


20


is an axially mounted coil spring that acts against drive member


19


and urges drive member


19


to the position shown in FIG.


4


A. Due to the connection between drive member


19


and paddle handle


14


by pin


38


, first spring


20


also acts to keep paddle handle


14


disposed within the recess


12


of tray


11


. An appropriate amount of force must be applied to paddle handle


14


to overcome the resistance provided by first spring


20


. Additionally, the biasing action of first spring


20


acts to maintain rattle-free engagement between paddle handle


14


and tray


11


.




A linkage member


21


is located proximate to base member


16


. Linkage member


21


has a first linkage end connection


22


located on one end. The first linkage end connection


22


allows for a pivotal connection between linkage member


21


and drive member


19


. The kinematical components such as drive member


19


and linkage member


21


located between handle


14


and operating mechanism


26


are referred to herein generally as mechanical linkage


44


.




At the other end of linkage member


21


is the second linkage end connection


23


. Second linkage end connection


23


is pivotally connected to operating mechanism


26


. Operating mechanism


26


is connected to base flange


17


by the operating arm pin


39


. Operating mechanism


26


is free to rotate partially about flange


17


via operating arm pin


39


. The operating mechanism


26


is composed primarily of two plates


30


and


31


. However, it is to be understood that various configurations of an operating mechanism


26


such as, for example, hooks, rotaries, sliders, etc. are possible, and all are to be included within the scope of the present invention. Use of these two plates


30


and


31


allows the offset handle assembly


10


to be used in either a lockable or an non-lockable configuration.

FIGS. 1-4B

show a non-lockable configuration and

FIGS. 5A-5D

shown a lockable configuration.




In the lockable configuration, a lock cylinder


46


having a flange


47


is provided. A flange connection end


50


of lock member


48


pivotally engages flange


47


. One way to provide the pivot action would be to shape the flange connection end


50


as a hook extending through a hole in flange


47


, although various other configurations are possible. The first operating mechanism member


30


has a first operating mechanism slot


33


roughly in the shape of a “v” located along a portion of its length. The second operating mechanism member


31


has a second operating mechanism slot


32


. The two slots


32


and


33


partially overlap one another. A lock member connection


52


is provided on one end of lock member


48


. An operating arm bolt


34


extends therefrom and through both slots


32


and


33


.




Turning of lock cylinder


46


results in linear movement of operating arm bolt


34


.

FIG. 5C

shows the offset handle assembly


10


in a locked configuration. Actuation of paddle handle


14


results in linkage member


21


urging the first operating mechanism member


30


to rotate. The second operating mechanism member


31


will not rotate, consequently causing the first and second rods


24


and


25


to remain stationary. This is because the operating arm bolt


34


will have the first operating mechanism slot


33


passed around it when the first operating mechanism member


30


rotates. The operating arm bolt


34


will not be urged against the second operating mechanism member


31


and no movement will be imparted to the second operating mechanism member


31


.




Turning the lock cylinder


46


so that the operating arm bolt


34


is moved to an opposite end of the second operating mechanism slot


32


from that shown in

FIG. 5C

results in an unlocked configuration of the handle assembly


10


. Rotation of the first operating mechanism member


30


causes the operating arm bolt


34


to be urged against the second operating mechanism member


31


, and hence resulting in movement of both the first and second rods


24


and


25


.




A nut


35


may be used to fixedly attach the operating mechanism bolt


34


onto the first and second operating mechanism members


30


and


31


.

FIGS. 1 and 2

show such an embodiment. In this case, the offset handle assembly


10


is in an unlocked configuration.




A second spring


29


is located between base flange


17


and first operating mechanism member


31


. Second spring


29


acts to bias the operating mechanism


26


to the position shown in FIG.


4


A. Biasing of operating mechanism


26


acts to keep the door


51


, shown in

FIG. 3B

, properly and securely latched, and also ensures that only a proper amount of force applied to paddle handle


14


will rotate operating mechanism


26


. Additionally, biasing action by second spring


29


acts to maintain rattle-free engagement between operating mechanism


26


and first rod


24


and second rod


25


. Also, rattle-free engagement with base flange


17


is maintained. Base flange


17


has a back base flange tab


40


extending therefrom proximate to operating mechanism


26


. Back base flange tab


40


is used to hold second spring


29


against first operating mechanism member


30


and therefore bias operating mechanism


26


to the position shown in FIG.


4


A.




Second operating mechanism member


31


has a first cable connection


27


pivotally attached to one end and a second cable connection


28


pivotally attached to an opposite end. First rod


24


is connected on one end to first cable connection


27


, and second rod


25


is connected on one end to second cable connection


28


. First rod


24


and second rod


25


are attached on opposite ends to latching mechanisms (not shown). Typically, first rod


24


and second rod


25


provide for a flexible connection between the latching mechanisms and operating mechanism


26


.




Upon actuation of the offset handle assembly


10


, these two latching mechanisms will actuate and cause an opening of the door that is being latched. Turning of paddle handle


14


results in paddle handle


14


being moved from the position shown in

FIG. 2

to the position shown in FIG.


3


B. This movement is indicated as arrow A—A. Rotation of paddle handle


14


causes drive member


19


to move as indicated by arrow B—B in

FIGS. 1 and 3B

.




The pivotal connection of linkage member


21


to drive member


19


results in linkage member


21


being moved along line C—C upon actuation of paddle handle


14


. This movement is substantially linear and is directed along the length of and behind the base member


16


. The connection of linkage member


21


to operating mechanism


26


results in a rotation of operating mechanism


26


as indicated by the arrows D—D in

FIGS. 1 and 2

. Rotation of operating mechanism


26


therefore results in a movement of first rod


24


and second rod


25


. This movement is indicated as arrow E—E concerning first rod


24


and arrow F—F concerning second rod


25


.





FIG. 4A

shows the offset handle assembly


10


in an unactuated position and

FIG. 4B

shows the offset handle assembly


10


in an actuated position. Actuation of offset handle assembly


10


can be prevented by a locking mechanism (not shown). Such locking mechanisms are commonly known in the prior art. A typical prior art locking mechanism could be housed within cylindrical lock recess


15


. Such a lock would selectively prevent rotation of drive member


19


, and consequently prevent unlatching of the door.




As demonstrated by the description of one preferred embodiment of the present invention, the offset handle assembly


10


is a relatively thin, compact unit, moving operating mechanism


26


to the side of tray


11


, as opposed to behind tray


11


as in the prior art, and allows for improved space savings. These space savings can result in increased applications for paddle handles, along with improved aerodynamic and economic benefits.




An alternative lockable embodiment of an offset handle assembly


10


is illustrated in

FIGS. 5A through 5D

. This embodiment possesses a similar offset mechanism


26


as described above with only minor design modifications, for instance a spacer


54


is present proximate to the first operating member


30


. Additionally, the rest of the offset handle assembly


10


is for the most part identical to the previously described embodiment. However, a lock cylinder


46


is shown inserted into the cylindrical lock recess


15


in

FIG. 5A. A

lock member


48


is incorporated into this design. The lock member


48


has a flange connection end


50


located on one end and connected to a flange


47


at the lock cylinder


46


. A lock member connection


53


is on an opposite end, which connects the lock member


48


onto operating mechanism


26


. Operation of such a configuration of the offset handle assembly


10


is as described above.




It will be appreciated that various modifications and changes may be made to the above described preferred embodiment of an offset handle assembly for use in a vehicle or structure without departing from the scope of the following claims.
