Certain types of vehicles commonly have storage compartments for baggage, equipment, and supplies. For example, recreational vehicles (RVs) typically have numerous compartments with doors hinged at the top, bottom, or side, with a cam lock or a handle on the door for opening and closing the door. Typically, handles for such storage compartment doors have a plunger which resides within the door, between the inner and outer door skins. Currently in the RV industry, lower end baggage doors use manually locking cam locks (lowest cost) and/or non-locking finger twist cam locks to secure the small doors. These low end manual locks generally are not capable of having power locking abilities with a slam action plunger. Higher end baggage handles may be power lock capable. Higher end baggage doors typically use a two-point application and not the direct drive slam action plunger seen in lower end baggage doors. Lowest cost cam locks are not desirable for the RV compartment door which may be dropped from a raised position and fall by gravity so as to slam shut. Such slam action is detrimental to the life of lowest cost locks as they are not slam capable and if rotated to a locked position and then closed, can cause paint damage. Also, lowest cost cam locks or current high cost handle assemblies typically do not allow for remote or power actuation by a key fob or key pad.
Recent door designs are becoming much thinner than in the past, so as to reduce weight and cost. Such thin doors make it more difficult for mounting conventional door handles. For example, on doors less than 1.26 inch, the inside skin must be cut to fit the plunger of the conventional handle.
Accordingly, a primary objective of the present invention is the provision of an improved handle assembly for a storage compartment door of a vehicle.

A further objective of the present invention is the provision of a handle assembly for a compartment door on a vehicle which is economical to manufacture and durable and safe in use.
The handle assembly of the present invention is intended for use on compartment doors on vehicles such as RVs and utility vehicles. The handle assembly is designed for use on a top-hinged door, but can also be used on doors hinged on either side edge or along the bottom edge. The handle assembly includes an inner housing which resides on the inner skin of the compartment door and an outer housing recessed within a cut-out in the outer skin of the compartment door. A handle is pivotally mounted on the outer housing. A plunger is slidably mounted on the inner housing, but does not reside between the inner and outer skins of the door. The plunger can be moved between an extended latched position to retain the door closed and a retracted unlatched position to open the door. When the handle assembly is mounted in a top-hinged door, the handle can be gripped from the top with the palm down or from the bottom with the palm up and pulled from a neutral or rest position wherein the plunger is extended and latched behind the door frame and an outwardly pulled position wherein the plunger is retracted from the frame to allow the door to be opened. The plunger is centrally mounted on the inner housing so that the handle assembly is non-handed for mounting on any edge of the door. An optional egress knob is rotatably mounted on the inner housing so as to retract the plunger from inside the compartment, whether the handle assembly is locked or unlocked so as to provide a safety override in case of a person inadvertently getting locked inside a compartment. The handle assembly may include a key lock for locking and unlocking the assembly. An optional power lock actuator may also be operatively connected to the handle assembly for remotely locking and unlocking the assembly. The design and inter-relation between the inner and outer housings allows for application on doors having a thickness of 0.79-1.25 inch, without the use of spaces. On thinner doors, spacers may be used between the inner and outer housings to achieve a minimum thickness of at least approximately 0.79 inch.
The handle assembly of the present invention is generally designated in the drawings by the reference numeral 10. The assembly 10 includes an inner housing 12 and an outer housing 14. The inner housing 12 resides against the inner skin 13 of the door, without any cut-outs in the interior skin 13. The outer housing 14 resides on the outer door skin 15, which includes a cut-out for the components associated with the outer housing 14. Thus, the compartment door is sandwiched between the inner and outer housings 12, 14.
The inner housing includes a plunger 16 which is slidably mounted within a channel 18 formed on the inner housing 12. Movement of the plunger 16 between extended and retracted positions is accomplished with a rod 20 and a pivot arm 22. More particularly, the rod 20 has a bent or turned outer end 24 which is received within a slot 26 in the plunger 16, as best seen in
The inner and outer housings 12, 14 are secured together by a plurality of screws (not shown). Preferably, the screws are recessed in the back of the inner housing 12 and extend into mounting posts 17 on the back of the outer housing 14.
A handle 40 is pivotally mounted to the outer housing 14. The handle 40 includes a pair of spaced apart legs 42,43 which extend through slots 44 on opposite sides of the outer housing 14 and are pinned to support arms 46 on the back of the outer housing 14 via pins 48. A pair of sealing gaskets 45 extend around each leg 42, 43 to seal out moisture, dust, and other contaminants from passing through the slots 44 into the interior of the handle assembly 10. Thus, the handle 40 can pivot about the axis of the pins 48 when the grip portion 50 of the handle 40 is pulled by a person. The grip portion 50 extends above and across a well 52 formed in the outer housing, and preferably is centrally mounted so that a person can grasp the grip portion 50 from either side of the well 52. Thus, when the handle assembly 10 is mounted in the door with the handle 40 extending horizontally, a person can reach their fingers into the top of the well 52 with the palm down to pull the handle 40, or alternatively can reach their fingers into the lower part of the well 52 with their palm up to pull the handle 40.
The free or terminal end of the leg 42 of the handle 40 is spaced closely to or engages the pivot arm 22. Therefore, when the handle 40 is pulled, the legs 42, 43 pivot about the pins 48, so that the leg 42 rotates the pivot arm 22 so as to move the plunger 16 from the extended latched position to the retracted unlatched position. A torsion spring 54 biases the handle 40 to the rest or neutral position, such that when the handle 40 is released, the force of the leg 42 on the pivot arm 22 is released and the pivot arm returns to the rest position by the force of the extension spring 36, so that the plunger 16 automatically returns to the extended latched position. When the compartment door is shut, either by manual force or by the force of gravity, the beveled edge of the plunger 16 will move across the door frame to push the plunger 16 back into the channel 18 to the retracted position. When the plunger 16 moves past the door frame, the bias of extension spring 36 will push the plunger 16 out of the channel 18 to the extended latched position to retain the door closed.
A lock cylinder 56 may be provided on the assembly 10 to prevent unauthorized or accidental opening of the compartment door. The key cylinder 56 is mounted in a boss 58 in the outer housing 14. An O-ring seal 60 is provided on the inner end of the cylinder 56. A rotatable actuator 62 is mounted to the inner end of the cylinder 56. A lock cam 64 is mounted on the actuator 62 for rotation therewith between a lock position and an unlock position. A spring 66 biases the lock cam 64 to the unlock position. The lock cam 64 includes a first arm 68 which extends through a slot in a guide 70. A second arm 72 of the lock cam 64 is attached to a lock arm 74 which is slidably mounted on the back side of the well 52 of the outer housing 14. A screw 76 extends through a slot on the lock arm 74 to mount the lock arm to the outer housing 14 for guiding the sliding movement of the lock arm 74. When a key is used in the cylinder 56 to lock the handle assembly 10, the cylinder 56 rotates the actuator 62, which in turns rotates the cam 64 so as to slide the lock arm 74 laterally such that a leg 78 on the lock arm 74 extends beneath the leg 43 of the handle 40 to preclude the handle 40 from being pulled from the neutral or rest position. The key can be turned in the key cylinder 56 in the opposite direction to unlock the handle assembly 10, by rotating the actuator 62 and the lock cam 64 so as to pull the lock arm 74 out of blocking engagement with the leg 43. The egress knob 32 functions independently of the lock cylinder 56, and can be operated regardless of whether the handle 40 is locked or unlocked.
The centered position of the plunger 16 allows the handle assembly 10 to be non-handed for use on any edge of a compartment door. The centered position of the handle 40 over the housing well 52 allows the handle to be grasped from either side, regardless of the horizontal or vertical orientation of the handle 40. The structure of the inner housing 12 and the plunger 16 allows the handle assembly 10 to be mounted on thin compartment doors, even less than one inch thick, without positioning the plunger 16 inside the door between the inner and outer skins.
The structure and components of the handle assembly provides several advantages over conventional compartment door handles, both in installation and in use. The construction of the handle assembly 10 allows the assembly to be used on a solid foam door with a single extruded cut-out extending through the door. Also, the depth of the pivot arm 22 and the height of the handles legs 42, 43 allow the handle assembly 10 to be used on a variety of doors having varying thickness. A spacer can be used between the inner and outer housings 12, 14 for use of the assembly on extremely thin doors. The extension spring 36 on the pivot arm 22 eliminates the need for a spring on the plunger 16, which allows a smaller plunger design without sacrificing plunger strength. The lock arm 74 locks the outside handle 40, while allowing the egress knob or handle 32 to work independently, even when the door is locked. Thus, the egress handle 32 is a safety feature in the event that the door accidentally closes on a person inside a large storage compartment. The torsion spring 54 on the handle 40 assures that the door will remain securely closed without requiring or depending on a mating configuration between the components of the inner and outer housings 12, 14. Also, the position of the key cylinder 56 on the outer housing 14, rather than on the handle 40, allows the assembly 10 to accommodate power actuation by a remote key fob, if desired. The low profile of the egress handle 32 also avoids accidental opening of the door by cargo behind the door.
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.
