Paddle-type door handles are well known for opening a door latch mechanism in various types of vehicles, including automobiles, industrial vehicles, utility vehicles, commercial vehicles and recreational vehicles. Typically, the paddle handle is mounted on the outside of the door, which may be a passenger door or a compartment door. The handle is connected to the latch mechanism through one or more linkages so as to release the latch and open the door. Many handles are provided with a lock to preclude unauthorized entry into the vehicle or the compartment. Normally, when the door is locked, the paddle handle does not move. However, some users mistakenly believe that the locked handle is merely stuck, and pull harder on the paddle in an attempt to open the door, which may lead to breakage of one or more components of the paddle handle.
Therefore, a primary objective of the present invention is the provision of an improved paddle handle assembly for a vehicle which is free floating when the door is locked.
Another objective of the present invention is the provision of a free floating paddle handle assembly having a drive plate and a driven plate which operate independently when the door is locked and which operate in unison when the door is unlocked.
A further objective of the present invention is the provision of an improved paddle handle assembly wherein a lock arm moves between locked and unlocked positions so as to disengage and engage actuation plates operatively interconnecting the paddle with the latch mechanism.
Another objective of the present invention is the provision of an exterior paddle handle assembly which can be operatively coupled to an interior handle assembly, with both handle assemblies being linked to the door latch mechanism.
Yet another objective of the present invention is the provision of a paddle handle assembly which is economical to manufacture and durable and safe in use.
These and other objectives will become apparent from the following description of the invention.
An improved paddle handle assembly is provided for a vehicle door having a latch mechanism movable between open and closed positions. The handle assembly includes a housing with interior and exterior sides, and a paddle pivotally mounted on the exterior of the housing for movement between open and closed positions. A logic assembly is mounted on the interior side of the housing. The logic assembly includes a drive plate and a driven plate, both of which are pivotally mounted on the housing. The driven plate is connected to the latch mechanism by linkage arms. A lock arm is also pivotally mounted on the interior of the housing for movement between locked and unlocked positions. The drive plate is disengaged from the driven plate when the lock arm is in a locked position, such that the latch mechanism remains closed when the paddle is moved to the open position. Thus, when the lock arm is locked, the paddle free floats. The drive plate is engaged with the driven plate when the lock arm is in the unlocked position, so as to open the latch mechanism when the paddle is moved to the open position. Thus, the drive plate operates independently of the driven plate when the lock arm is in the locked position so as to preclude opening of the latch mechanism, and the drive and driven plates operate in unison when the lock arm is in the unlocked position so as to open the latch mechanism.
The free floating paddle handle assembly of the present invention is generally designated in the drawings by the reference numeral 10. The handle assembly 10 includes a housing 12, a paddle 14 pivotally mounted to the housing for movement between open and closed positions, and a logic assembly 16 mounted on the rear or interior side of the housing 12. The handle assembly 10 is intended for, but not limited to, use on the outside or exterior of a vehicle door to provide access to the interior of the vehicle or a vehicle compartment. As described below, the handle assembly 10 is operatively connected to the latch mechanisms of the vehicle which allow the door to be opened and closed.
The paddle 14 is mounted to the front or exterior side of the housing 12 with an elongated pin or axle 18, and appropriate bushings 20. The housing 12 also includes a lock cylinder 22, with a seal 24 and an actuator 26, as best seen in
The logic assembly 16 has three primary components: a drive plate 28, a driven plate 30, and a lock arm 32. The drive plate 28 and driven plate 30 are pivotally mounted to the housing 12 via a rivet 34 which defines a pivot axis 36. The lock arm 32 includes a slot 38 through which the rivet 34 extends. A retaining washer 40 is retained by a stake or swedging on the rivet 34 so as to retain the lock arm 32, while allowing the lock arm 32 to slide or move relative to the rivet 34 via the slot 38.
The drive plate 28 includes an L-shaped slot 42 having a float leg 44 and a drive leg 46. As seen in
A drive arm 60 is mounted on an end of the pin or axle 18 of the paddle 14, and resides on the exterior of the housing 12. The free end of the drive arm 60 engages a tab 62 on the drive plate 28.
A spring 64 has a first end connected to the housing 12 and a second end connected to the drive plate 28. A second spring 66 has a first end connected to the housing 12 and a second end connected to the driven plate 30. The springs 64, 66 bias the drive plate 28 and driven plate 30, respectively, to a neutral or de-actuated position when the paddle 14 is in the closed position.
A pair of brackets 65 are secured with the bolts 67 to the housing 12 with the door skin sandwiched between the brackets 65 and the perimeter flange 69 of the housing 12, so as to mount the handle assembly 10 to the door.
An over center spring 71 has opposite ends secured to the lock cylinder sleeve 73 on the back of the housing 12 and to the lock arm 32. The actuator 26 of the lock cylinder 22 extends through a butterfly drive slot 75 on the lock arm with a washer 77 staked or swedged to the end of the actuator 26. The spring 71 biases the lock arm 32 to the fully locked or fully unlocked positions, the lock arm 32 has lost motion via the butterfly slot 75, such that it allows the lock cylinder 22 to return to its home position for key removal, while the lock arm 32 remains biased in the locked or unlocked position, as is conventional in the art.
The handle assembly 10 has two operating modes: locked and unlocked. When the lock cylinder 22 is rotated to the locked position and back to the home position, and the paddle 14 is in the closed position, the components of the logic assembly 16 are positioned, as shown in
When the lock cylinder 22 is rotated to the unlocked position and back to the home position, the actuator 26 pivots the lock arm 32 to the position shown in
Thus, when the lock cylinder 22 is rotated to the lock position and back to the home position, the lock arm 32 is in the lock position and the drive plate 28 moves independently of the driven plate 30 when the paddle 14 is pulled to the open position. When the lock cylinder 22 is rotated to the unlock position and back home, the lock arm 32 is in the unlocked position, and the drive plate 28 and drive plate 30 move in unison upon actuation of the paddle to the open position. When the vehicle door is locked, the paddle 14 free floats with no effect. When the door is unlocked, the paddle 14 will open the latch when pulled open.
The lock arm 32 has a range of motion of approximately 15° between the locked and unlocked positions. The drive plate 28 and the driven plate 32 have a range of motion of approximately 20°.
The inside handle assembly 70 includes a paddle 88 which is movable between closed and opened positions. When the lock arm 32 of the outside handle assembly 10 is locked, a person inside the vehicle can move the paddle 88 from the closed to the open position, which causes the fourth link arm 84 to pivot the lock arm 32 to the unlocked position, while the third linkage arm 80 pivots the driven plate 30 so that the linkage arms 76, 78 open the upper and lower latches 72, 74. When the interior paddle 88 is pulled, the plate 82 rotates to push a pin 90 attached to the lock arm 32 of the logic assembly 16 so as to pivot the lock arm 32 from the locked to the unlocked position. Thus, the inside handle assembly 70 overrides the outside handle assembly 10 when a person inside the vehicle wants to open the vehicle door.
It is understood that the inside paddle 88 is normally biased to the closed position. Similarly, the inside actuation plate 82 is normally biased to a neutral position. Also, it is understood that the handle assemblies 10, 70 can be used in a vehicle having only one upper or lower latch, and does not require both an upper and lower latch. Also, an inside handle assembly is not used on non-passenger vehicle compartments.
The invention has been shown and described above with the preferred embodiments, and it is understood that many modifications, substitutions, and additions may be made which are within the intended spirit and scope of the invention. From the foregoing, it can be seen that the present invention accomplishes at least all of its stated objectives.
