Abstract
A safety release handle assembly for a trunk of a vehicle is positionable within the trunk or compartment space of the vehicle to allow for opening of the trunk or compartment lid from within the trunk or compartment. The safety release assembly comprises a housing and a handle positioned within a recess of the housing. The handle is connectable to a release mechanism of the trunk lid and is movable to actuate the release mechanism to open the trunk lid from within the trunk space. The handle provides a mechanical advantage such that the release mechanism may be actuated upon exertion of less than or equal to approximately 20 Newtons at the handle. The safety release assembly may further include an illumination source, whereby the handle may be illuminated to assist viewing of the handle when the trunk lid is closed.
Description




BACKGROUND OF THE INVENTION




This invention relates generally to a handle for opening a door to a compartment, and more particularly, a handle for opening a deck lid of a vehicle from inside the space enclosed by the deck lid.




Typically, the deck lid or door to trunk spaces are opened by a key being inserted and turned in a lock cylinder from a position exteriorly of the deck lid or by a button or lever that is positioned within the passenger compartment of the vehicle. While it has been suggested that a handle be placed in the interior of the trunk space, because of numerous difficulties, to date, vehicle manufacturers have not included a device specifically for opening the trunk from the inside of the trunk space. Even fold down rear seats, which are common in many vehicles today, cannot be folded down from within the trunk space. Although placement of a release mechanism in the trunk space has been suggested in the prior art, no commercially acceptable mechanism or device has been developed. Therefore, if a person is within the trunk space when the deck lid is closed, there is no way for a person to open the deck lid and get out of the trunk.




When the deck lid is closed, the space within the trunk is typically small and very dark. Although a light source is typically provided in a trunk to provide light to the trunk space when the trunk space is open, these lights are deactivated when the trunk is closed, in order to prevent excessive drain on the battery of the vehicle. Therefore, when a person is trapped within a trunk, it is nearly impossible to see anything within the trunk, such that even if a release mechanism were operable within the trunk, a person would not be able to find the mechanism after the deck lid had been closed. Furthermore, due to the cramped and tight space within a trunk, a person's movements to reach and operate a release mechanism are extremely restricted.




This inability to open a trunk of a vehicle from inside the trunk space has unfortunately lead to many injuries and even deaths over the years. When the deck lid is closed, the interior space of the trunk may reach extreme temperatures during the summer time, such that a person can only survive therein for a short period of time. Typically, these injuries and deaths occur to children, who enter the trunk to either play or hide and then trap themselves within the trunk by closing the deck lid.




Therefore, there is a need in the art for an interior trunk release mechanism which is highly visible under minimal lighting conditions such as when the deck lid of the trunk is closed. Furthermore, the release mechanism should be easily recognizable and operable even by children, and should avoid damage or deterioration of existing vehicle systems such as the battery or electrical system while remaining operable.




SUMMARY OF THE INVENTION




The present invention is intended to provide a mechanical apparatus for activating a release mechanism for a deck lid of a trunk of a vehicle from within the interior space of the trunk.




According to a first aspect of the present invention, an apparatus is adapted for use in opening a deck lid of a vehicle and is positionable within a compartment substantially enclosed by the deck lid. The apparatus comprises a handle for activating a release mechanism for opening the compartment which is of a bright color and in contrast to a background upon which it is installed. Preferably, the color is selected to convey a safe and friendly image to a child, such as a yellow or bright green color.




Preferably, the apparatus includes at least one illumination source which is at least occasionally activated to provide illumination of the handle, and a control circuit for at least temporarily activating the at least one illumination source when the deck lid is closed. The control circuit activates the at least one illumination source in response to an occurrence of an activating event.




In one form, the illumination source is at least one light emitting diode which provides either direct or indirect illumination to the handle of the present invention. The illumination source is temporarily activated upon closure of the deck lid and may be further activated upon a second activating event, such as movement of the handle or detection of a person or animal within the trunk space by a motion detector or temperature sensor or the like.




According to another aspect of the present invention, the apparatus includes a handle, an illumination source and a control circuit. The handle is interconnected to a release mechanism of the compartment and at least partially provides a mechanical advantage such that the release mechanism may be activated upon exertion of less than 20 Newtons in a predetermined direction on the handle. The illumination source provides illumination to the handle and is activated by the control circuit upon an occurrence of an activating event.




According to yet another aspect of the present invention, an apparatus is adapted for use in opening a compartment of a vehicle and is positionable within the compartment and substantially enclosed by a lid. The lid is openable by an electrically controlled latch. The apparatus is adapted to activate the latch in response to an activation of the apparatus.




In one form, the apparatus includes an electromechanical device which activates the latch when at least a portion of the device is moved. Preferably, the electromechanical device is a button and the activation is a pressing of the button.




Therefore, the present invention provides a trunk release apparatus which is easily recognizable and operable by a child, as children are the ones typically harmed by being trapped in a trunk. The release apparatus is easy to activate and is preferably a bright friendly color so as not to frighten or confuse a child who may be trapped within the trunk. Furthermore, an illumination source is preferably provided to increase the visibility of the release mechanism. The illumination source should only be activated for a limited period of time in order to prevent excessive drain on the battery of the vehicle.




These and other objects, advantages, purposes and features of this invention will become apparent upon review of the following specification in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now specifically to the drawings and the illustrative embodiments depicted therein, there is shown in

FIG. 1

a safety release apparatus or assembly


10


, which includes a handle


12


which is interconnected to a release mechanism


14


for opening a deck lid or trunk lid or door


16


of a trunk or storage compartment or space


18


of a vehicle


20


. The vehicle


20


may be a sedan, coupe or even a hatchback or the like, which includes a trunk storage compartment space


18


substantially enclosed by a deck lid or door


16


, such as a trunk or the like. Handle


12


of safety release apparatus


10


is interconnected with release mechanism


14


of deck lid


16


such that release mechanism


14


is activated, and deck lid


16


subsequently opened, in response to a movement of handle


12


. Safety release apparatus


10


is mounted on an interior surface


16




a


of either the deck lid


16


or elsewhere within trunk space


18


, so as to allow an operator of safety apparatus


10


to open the trunk from within trunk space


18


. Most preferably, safety release apparatus


10


is mounted on a downward extending portion or waterfall


16




b


of deck lid


16


, as shown in FIG.


1


. However, clearly safety release apparatus


10


may be mounted elsewhere within trunk space


18


of vehicle


20


, such as on a side wall of the trunk space or the like, without affecting the scope of the present invention.




Handle


12


of the present invention is preferably injection molded from a resinous polymeric material such as polycarbonate/PBT or polycarbonate/ABS or the like and includes a long handle portion


12




a


and a shaft portion


12




b


(

FIG. 4



a


), which provides for a pivot axis


22


of handle


12


. However, handle


12


may alternatively be a switch, push button or any other electromechanical device which may be electronically interconnected to an electronic latch mechanism, such that movement of at least a portion of the device releases the release mechanism in order to open the trunk. Handle


12


is designed and formed so as to be easily recognizable as an opening device for a door or the like, and further is formed with rounded edges along the handle portion


12




a


so as to make it a comfortable handle for a child or other occupant within the trunk to grasp and operate. Handle


12


may further include text or a picture on a facing surface


12




c


to convey to an operator of handle


12


that handle


12


is for opening the trunk. Furthermore, the color of handle


12


is selected to be a “friendly” color for children, so that any small child which may become trapped within trunk space


18


will not fear the handle as being something that is hot or otherwise harmful to touch. Preferably, the color selected is a bright green or yellow, which has been shown to convey a bright yet “friendly” or cool to touch appearance to the handle. It is important that the handle be child friendly so that even the smallest and youngest children who may be trapped within the trunk will not be afraid to operate the handle


12


.




By providing a light color which does not convey an image of heat or otherwise harmful material, the handle


12


of the present invention is more likely to be grasped and operated by small children than a handle which may otherwise be of a “harmful” color, such as red or orange, which a child may believe is hot to touch. In order to make handle


12


more visible in minimum lighting conditions, handle


12


is also preferably mounted adjacent to a background


24


that is of a substantially darker color than handle


12


, so as to provide a stark contrast between the handle and its background for better visibility of the handle in minimal lighting conditions. The background


24


may be a surface of a housing


28


for safety release assembly


10


or may be an interior surface of the trunk space


18


or deck lid


16


itself.




Safety release apparatus


10


preferably is installed within a housing


28


, which is secured within trunk space


18


such that handle


12


is positioned within a recess


30


of housing


28


. Housing


28


is preferably injection molded from a resinous polymeric material such as polycarbonate/PBT or polycarbonate/ABS or the like and may be black or another dark color. Housing


28


functions to protect handle


12


from being bumped or damaged by items which may be stored within trunk space


18


of vehicle


20


. Not only does this prevent damage to handle


12


or other components of safety release apparatus


10


, but housing


28


also substantially precludes the possibility of handle


12


being accidentally contacted and moved by the stored items so as to prevent unintentional opening of trunk space


18


.




As best shown in

FIGS. 2-4



a


, housing


28


includes a substantially flat and outward extending flange


32


along its rearward end and a raised, perimeter or front surface


33


. Flange


32


allows for easy installation of the present invention, as fasteners or adhesive or the like may be inserted through or applied to flange


32


and then secured to an interior surface of either deck lid


16


or other interior surface of the trunk space


18


of the vehicle


20


. Clearly, the safety release mechanism


10


may be installed on a vehicle during the assembly of the vehicle by the manufacturer, or may be installed later as an after market unit, without affecting the scope of the present invention.




Handle


12


is preferably positioned within recess


30


of housing


28


below or behind the plane of perimeter surface


33


such that the handle may pivot about its axis


22


within recess


30


. Perimeter surface


33


helps protect handle


12


from stored items within trunk or compartment


18


, and helps prevent accidental activation of handle


12


. Recess


30


may also include at least one stop


30




a


, which limits rotational travel of handle


12


within a predetermined range. Preferably, as shown in

FIGS. 4



a


and


4




b


, handle


12


includes a cylindrical bearing or barrel section


35


which has longitudinally extending sections


35




a


separated by slots which are generally parallel to the pivot axis


22


of handle


12


. The slots allow the longitudinal sections


35




a


to flex inward as shaft


12




b


is inserted into opening


28




a


in housing


28


. Barrel section


35


may also include a plurality of resilient, angled flange or tabs


35




b


formed at a free end


35




c


of longitudinal sections


35




a


and extending radially outwardly therefrom. Tabs


35




b


each have an inclined outer edge or surface


35




d


and a substantially flat, planar edge


35




e


extending generally perpendicular to axis


22


when handle


12


is mounted in opening


28




a


. As shaft


12




b


is inserted into opening


28




a


, the inclined surfaces


35




d


of tabs


35




b


engage the opening


28




a


and cam the sections


35




a


inwardly and guide insertion of barrel section


35


through opening


28




a


. As tabs


35




b


protrude through opening


28




a


, flat edges


35




e


engage an interior surface


28




e


of housing


28


adjacent opening


28




a


so as to snap fit handle


12


into housing


28


. This allows handle


12


to be easily rotated within opening


28




a


, yet substantially precludes handle


12


from being pulled outward from opening


28




a.






Additionally, a biasing member


34


such as a torisional spring or the like (FIG.


5


), may be provided about shaft


12




b


of handle


12


in order to bias handle


12


in an initial position. Biasing member


34


preferably is positioned around a lower end


37


of handle shaft


12




b


, such that one end


34




a


of biasing member


34


engages a stop tab


34




b


on housing


28


and another end


34




c


engages a slot


37




a


along lower portion


37


of shaft


12




b


. This substantially fixes both ends


34




a


and


34




c


of biasing member


34


so that rotational movement of handle


12


about axis


22


winds the torisional spring, which then provides a rotational force on shaft


12




b


to return handle


12


to its initial position.




Preferably, handle


12


is interconnected to release mechanism


14


by a lever


36


and a cable


38


, as best shown in FIG.


5


. The lever


36


is attached to lower portion


37


of shaft


12




b


, which extends downward from handle


12




a


through barrel section


35


and is of a lesser diameter than barrel section


35


. Lower portion


37


is substantially non-circular at its free end and includes slot


37




a


extending longitudinally along its axis


22


. Slot


37




a


allows lower portion


37


to flex inward for attachment of lever


36


thereto and further provides for the end


34




c


of biasing member


34


, as discussed above. An annular groove


37




b


may also be included around lower portion


37


for securing lever


36


thereto.




As best shown in

FIGS. 4



a


and


4




b


, lever


36


is preferably a substantially straight lever arm, which includes an opening


40


at one end


36




a


through which lower portion


37


of shaft


12




b


is inserted, such that lever


36


is fixedly secured to shaft


12




b


of handle


12


. Lever


36


may include angled tabs


40




a


protruding inwardly at opening


40


to engage a corresponding lip


37




c


along groove


37




b


of shaft


12




b


, thereby snapping lever


36


onto lower portion


37


to prevent lever


36


from being removed from shaft


12




b


. Tabs


40




a


of lever


36


function similarly to tabs


35




b


of barrel section


35


as they engage lip


37




c


and prevent lever


36


from being removed from shaft


12




b


. As lower portion


37


of shaft


12




b


is inserted through opening


40


in lever


36


, tabs


40




a


cam lower portion


37


inward, as slot


37




a


allows lower portion


37


to flex inwardly, until tabs


40




a


snap into groove


37




b.






Preferably, both opening


40


and lower end


37


of shaft


12




b


are correspondingly substantially non-circular, such that lever


36


cannot rotate relative to shaft


12




b


. More preferably, opening


40


and lower shaft end


37


are substantially square as shown in FIG.


5


. At a second end


36




b


of lever


36


, there is located an attaching slot


42


or the like, which may be secured to cable


38


. As shown in

FIGS. 4 and 5

, an underside of housing


28


provides for a cavity in which lever


36


is also substantially encased, again to prevent damage to the lever and to further prevent accidental activation of the release mechanism


14


.




Cable


38


preferably comprises an inner cable


38




a


and an outer sheath


38




b


through which inner cable


38




a


may travel. At each end


38




c


and


38




d


of inner cable


38




a


is a pin


44


for engaging a corresponding slot or other attaching means. Pin


44


on a first end


38




c


of inner cable


38




a


is secured to slot


42


on lever


36


while pin


44


on a second end


38




d


of inner cable


38




a


is likewise secured to a slot (not shown) on release mechanism


14


. Outer sheath


38




b


of cable


38


is secured to housing


28


through a cable opening


28




b


in one side and to a bracket (not shown) substantially adjacent release mechanism


14


. Movement of first end


38




c


of inner cable


38




a


therefore results in a substantially similar amount of travel of second end


38




d


of inner cable


38




a


, while cable


38


is maintained by sheath


38




b


in a predetermined path between housing


28


and release mechanism


14


.




When handle


12




a


is grasped and pivoted about its pivot axis


22


, lever


36


is correspondingly pivoted about the same axis


22


. As shown in

FIG. 5

, this results in second end


36




b


of lever


36


traveling along an arcuate path which causes a linear travel of substantially the same distance to occur to first end


38




c


of inner cable


38




a


. As first end


38




c


travels along the arcuate path, second end


38




d


of inner cable likewise is moved a linear distance substantially equal to the linear travel of first end


38




c


. Safety release assembly


10


is designed such that pivoting handle


12




a


until handle


12




a


is approximately at stop


30




a


in recess


30


results in a predetermined amount of cable travel in cable


38


so as to activate release mechanism


14


, thereby opening deck lid


16


of vehicle


20


. Preferably, this pivot requirement is less than approximately a 15 degree rotation of handle


12


. Although shown and described as including a lever and cable to activate release mechanism


14


, clearly the present invention may incorporate other mechanical means for interconnecting the handle


12


to the release mechanism


14


, without affecting the scope of the present invention. For example, second end


36




b


of lever


36


may be directly connected to release mechanism


14


or to another form of linkage, such as an additional lever arm or the like.




Although safety release assembly


10


is shown and described as including a handle, lever and cable system, it is envisioned that other means of activating a release latch or mechanism may be implemented. For example, for a vehicle including an electronically operated latch, the safety release assembly may include an electromechanical device for signaling or activating the latch and thus opening the deck lid. The electromechanical device may be a push button, handle or switch positioned within the trunk space and electronically interconnected with the latch mechanism, such that activation or movement of the device energizes a solenoid within the latch mechanism or otherwise causes the latch mechanism to release, thereby opening the trunk. The device may be a bright color and may be easily recognized and operated by a small child in accordance with the present invention as discussed above.




Preferably, safety release assembly


10


further includes at least one illumination source


46


for providing illumination to handle


12


, and an electronic control circuit


48


for at least temporarily activating the illumination source


46


in response to at least one activating event, as discussed below. The illumination provided by illumination source


46


allows a person who may be trapped within trunk space


18


to see handle


12


so as to grasp the handle and open the trunk, as the trunk space would otherwise be too dark for a person to see where the handle is located. This is especially critical when a child is trapped in the trunk, as a child would not even know to look for such a handle, much less know where the handle may be positioned within the trunk. Most preferably, the light emitted by illumination source


46


will be of low intensity and a “friendly” color to avoid frightening a child, who may believe that the handle is hot if it is illuminated by a bright light or the like.




Illumination source


46


is thus provided to illuminate handle


12


when the deck lid


16


of vehicle


20


is closed, as the trunk space


18


becomes very dark when fully enclosed. Preferably, illumination source


46


is at least one light emitting diode (LED) or other non-incandescent illumination source (such as organic or inorganic electroluminescent sources, phosphorescent sources, etc.), as these types of illumination sources minimize the drain on the vehicle battery when they are activated, as well as being highly durable and long-lasting. The LEDs may be selected to provide illumination in a preferred color, such as green or yellow, and may be selected to draw a minimal amount of current from the vehicle battery or the like. Preferably, an LED is selected which draws less than about 45 milliamps when activated, and more preferably, the LED draws less than or equal to about 30 milliamps when activated. Such LEDs are commercially available, examples being a Hyper-Bright LED manufactured by Siemens or other LEDs manufactured by Hewlett-Packard. Most preferably, illumination source


46


is at least two LEDs, so that if one fails for some unforeseen reason, there is still at least one additional LED providing illumination to handle


12


. Although illumination source


46


is shown and described as an LED or the like, clearly other illumination sources may be provided in varying locations within the trunk without affecting the scope of the present invention. For example, illumination source


46


may be within handle portion


12




a


of handle


12


itself, to provide direct illumination of handle


12


. Furthermore, illumination source


46


may be provided by handle


12


being made out of a highly visible and glowing phosphorus material or the like. Alternatively, illumination source


46


may be an incandescent source, such as a filament lamp, a halogen lamp, a neon lamp, or the like. Preferably, illumination source


46


may also serve as the standard trunk light, which is normally activated when the trunk or deck lid is opened, thereby providing light to the entire trunk space when the trunk is closed.




As shown in

FIGS. 4



a


and


5


, illumination source


46


is most preferably located on a circuit board or chip


50


containing control circuit


48


, and is substantially encased along with control circuit


48


within housing


28


in order to prevent damage to illumination source


46


or control circuit


48


by items stored within the trunk. Illumination source


46


may project light through at least one slot or opening


52


in a side wall


30




b


of recess


30


such that illumination source


46


is directed toward handle portion


12




a


of handle


12


. Handle portion


12




a


may also be twisted or angled such that the facing surface


12




c


of handle portion


12




a


is angled toward illumination source


46


in order to receive and reflect illumination from illumination source


46


over a greater surface area. A removable access panel


28




c


(

FIG. 2

) may also be included on housing


28


to provide for easy access for installation and maintenance of both control circuit


48


and illumination source


46


within a cavity


28




d


formed by housing


28


. Preferably, control circuit


48


is snap fit onto an interior side


30




c


of side wall


30




b


such that illumination source


46


is aligned with slot


52


. Control circuit


48


further includes a wiring harness and connector


60


for connecting control circuit


46


to a power source located on vehicle


20


, such as the vehicle battery or the like.




Control circuit


48


functions to activate illumination source


46


upon an occurrence of an activating event. The activating event may be the closing of deck lid


16


and/or the closing or folding back of any fold-down rear seats which may be present in vehicle


20


. For example, as shown in

FIG. 6

, vehicle


20


may include a trunk closure sensor


54


and/or a seat sensor


56


to provide a signal to control circuit


48


when the trunk is closed or the seats are folded to their upright position, thereby enclosing trunk space


18


. Preferably, control circuit


48


also functions to deactivate illumination source


46


after a period of time following the activating event. For example, control circuit


48


may include a timer or other timing mechanism


58


which triggers deactivation of illumination source


46


after a predetermined period of time, such as thirty minutes or an hour, has elapsed following the initial activation of illumination source


46


. Control circuit


48


continues to reset and reactivate illumination source


46


upon subsequent occurrences of one or more activating events, following deactivation of illumination source


46


after the predetermined period of time has elapsed.




Referring to

FIG. 6

, control circuit


48


may also activate illumination source


46


in response to additional activating events, such as an ignition switch


62


of vehicle


20


being activated, a door sensor


64


signaling that a door of vehicle


20


is being opened or closed or other functions of vehicle


20


which pertain to the entering or leaving of vehicle


20


or movement of the vehicle. Safety release assembly


10


may further include a motion detector or sensor


66


(such as a pyro detector, preferably a low current pyro detector) and/or a temperature sensor


68


such as a bolometer within trunk space


18


, so as to provide a signal to control circuit


48


when a movement or predetermined temperature of an object in trunk space


18


is detected. The present invention may also include a handle sensor


70


which detects movement of handle


12


to provide an additional signal to control circuit


48


. Control circuit


48


may then, in response to a signal from the motion detector


66


, the temperature sensor


68

An alternate embodiment of the present invention provides for a module, which includes a handle, illumination source, control circuit, and housing similar to those discussed above, and further includes a license plate holder and lock cylinder for the deck lid which are positioned on an exterior surface of the deck lid. This embodiment may also include an exterior handle such that the trunk may be opened from outside without having to insert a key within the lock cylinder or otherwise enter the vehicle to release the trunk release lever from within the vehicle. The module is installed through an opening in the trunk lid and preferably includes a lock cylinder and release mechanism for opening the trunk.




Therefore, the present invention provides a safety release apparatus for opening a deck lid or trunk of a vehicle from inside the trunk space. The apparatus of the present invention is easy to install in the vehicle, and is easily recognized and operated by a small child that may become trapped within the trunk of the vehicle. The color and intensity of the handles and illumination are selected to convey a friendly, non-hot appearance to the handle, such that a child will easily see the handle and not be afraid to grasp the handle in order to open the trunk. Furthermore, the control circuit of the present invention activates the illumination source or other auxiliary signal in response to an activating event and deactivates the illumination source after a period of time in order to minimize the overall drain on the vehicle battery. The illumination source is also selected to be a non-incandescent device, such as an LED or the like, which is highly durable and long lasting, yet requires a minimal amount of energy from the battery of the vehicle, even while it is activated. Although the illumination source and control circuit of the present invention require connection to an electrical power source in order to provide illumination to the handle of the present invention, no electrical power is required to operate the handle and thus release the release mechanism in order to open the trunk of the vehicle. The handle, lever, cable and release mechanism are all mechanical devices, such that the trunk may be opened even when there is a power loss to the vehicle itself. Furthermore, even if power is lost to the vehicle, the color of the handle is preferably selected to be a light bright color, and starkly contrasts the background on which the handle is installed so as to remain visible in very low light conditions.




Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the invention, which is intended to be limited only by the scope of the pending claims, as interpreted to the principles of patent law.
