Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to door-activated switches and to doorstop assemblies for vehicles. More particularly, the present invention relates to a door-activated electrical switch and a door stop or motion damper for a vehicle door, combined into a single assembly.




2. Description of the Background Art




Door-activated switches, for activating an interior light, a dashboard or console indicator light, and/or an audible buzzer, are well-known and are used in substantially all vehicles. Typically, the switches are secured along a side portion of a vehicle door frame, adjacent a door hinge, and are operated by the opening and closing action of the vehicle door, alternately releasing and depressing a pushbutton activator as the vehicle door is opened and closed.




Many vehicles also conventionally use a door stop or damper, for damping or preventing further inward movement of a closing vehicle door, when it approaches or reaches a fully closed orientation thereof. Typically, such stop members are constructed of semi-rigid rubber or the like, and are either secured to the door frame, or to a free edge of a vehicle door, in a location remote from the hinge, where an edge of the door contacts the frame.




When using the previously known components, a complication could arise if an adjustment was made to set the proper extension of a stop member from a vehicle body panel, that might require separate adjustment of a door-activated switch, to compensate for the first adjustment made to the stop member.




One type of known door bumper, specifically designed for use with a sliding door on a vehicle such as a van or the like, is disclosed in U.S. Pat. No. 5,791,723 to Bell et al.




Additionally, there are known devices for providing a weather-resistant seal around a conventional door-activated switch.




U.S. Pat. No. 4,665,285 to Shiraishi, issued May 12, 1987, discloses a rubber bumper device which attaches on to an edge portion of a vehicle door, using specially designed mounting pins. The rubber bumper device of Shiraishi is adapted to be placed on an edge of a vehicle door, in a location which lines up adjacent to a conventional door switch on a vehicle body panel when the door is fully closed.




The bumper device of Shiraishi does not include a switch, but instead, pushes against a push rod of the conventional door-activated switch, when the door is closed, to switch off an interior light in the vehicle. The conventional switch, which is activated by the device of Shiraishi, is located on the vehicle body such that the switch push rod is operatively engaged by a central portion of the bumper.




A peripheral wall of the bumper which extends around an outer edge thereof, is formed of soft rubber or the like, and surrounds the conventional switch as a weather seal, when the vehicle door is closed thereagainst.




Although the known devices are effective for their intended uses, a need still exists in the art to simplify and reduce costs by combining functions of several components into fewer components, and where possible, to combine the functions of multiple components into a single assembly.




SUMMARY OF THE INVENTION




The present invention provides a combined doorstop and switch assembly for a vehicle, which may be attached to the vehicle as a single integral unit, and which may advantageously be adjusted in a single operation. In the preferred design of the assembly hereof, the switch is continuously protected against the entry of water, dirt, and other foreign matter thereinto, regardless of whether the door is open or closed.




The primary components of the combined doorstop and switch assembly, in accordance with the present invention, are a bumper body for attachment to a vehicle body panel, a switch assembly which is housed inside and secured to the bumper body for being supported thereby, and optionally, a weather-resistant cap for sealingly and protectively covering the switch.




Preferably, the bumper body is formed of a flexibly resilient and semi-rigid material appropriate for the door-stopping function thereof, such as, e.g., rubber or a suitable elastomer. A preferred material for the bumper body is an EPDM (ethylene propylene diene monomer) elastomer.




The bumper body has a hollow chamber or recess formed centrally therein, for receiving and securely holding the switch.




In a first preferred embodiment of the invention, the bumper body is formed in a barrel shape, and has a helical, external groove formed around the exterior surface thereof, for positioning the assembly in a vehicle body panel. Also in the first preferred embodiment, the bumper body has an annular interior groove formed in the interior surface thereof in communication with the hollow chamber, for retentively receiving a portion of the switch, and a peripheral external edge of the cap therein, with the cap disposed in covering relation to the switch.




In a second, alternate embodiment of the invention, the bumper body and cap are formed as an integral unit, and the switch is slidably placed thereinto from an end opposite the cap.




The switch is preferably housed within the hollow chamber of the bumper body and includes multiple components, including a case and an actuator portion housed in the case and being extensible and retractable therein. The actuator portion is preferably provided by a push rod member slidably disposed in the case for movement therein, with a spring, or other means for biasing an outer end of the push rod member outwardly from the case, also making up part of the switch. The switch also includes a first contact disposed in the case, a second contact disposed in the case and spaced apart from the first contact, means for electrically connecting the first and second contacts, and an electrical coupling in electrical communication with the first and second contacts.




As previously noted, in the preferred embodiment of the present invention, the assembly includes a flexibly resilient weather-resistant cap or cover means for protectively covering the switch. The cap is provided for resisting the entry of water, dirt and other impurities into the switch. The outer peripheral edge of the cap may fit sealingly into the interior annular groove of the bumper body. Alternatively, the cap and bumper body may be made as a single integral switch housing member.




Accordingly, it is an object of the present invention to provide an apparatus for attaching to a vehicle body to provide both a doorstop and a switch in a single assembly.




It is a further object of the present invention to provide a combined switch and door stop which is protected from water, dirt and other foreign matter.




It is yet a further object of the present invention to provide a combined switch and door stop which is adjustably attachable to a vehicle body panel.




It is an advantage of the present invention that during the process of assembling a vehicle, the single component accessory hereof can be installed more quickly, and less expensively, than the two components which it replaces.




It is another advantage of the present invention that the depth of the door stopper, and the operative position of the door-activated switch, may be adjusted together in a single operation, and when the door stopper is set to the correct depth with respect to the body, the switch is also automatically placed at the correct extension thereof.




For a more complete understanding of the present invention, the reader is referred to the following detailed description section, which should be read in conjunction with the accompanying drawings. Throughout the following detailed description and in the drawings, like numbers refer to like parts.

of the drawings, a door frame portion


10


of a vehicle body


12


is shown with a closed door


11


in place therein. A combined doorstop and switch assembly


14


, according to the present invention, is shown in phantom behind the door


11


, mounted in the door frame


10


. The vehicle door

according to the invention.




Overview of the First Preferred Embodiment




A combined doorstop and switch assembly


14


, in accordance with a first embodiment of the present invention, includes a bumper body


16


(

FIG. 2

) for attaching to a vehicle body panel


10


, and a switch


18


which is housed inside, and is integrally secured to the bumper body


16


. A protective cap or cover member


15


is optionally provided secured to the bumper body


16


and covering the switch


18


. Each of these components of the assembly


14


will be discussed in further detail below.




The Bumper Body




The bumper body


16


is formed of a resilient yet semi-rigid material, which may be rubber or a durable elastomer. A preferred material for the bumper body is an EPDM (ethylene propylene diene monomer) elastomer. The bumper body


16


is of a strength and thickness sufficient to make it durable enough to serve as a door stop, or energy absorbing damper, when in place in a vehicle.




The door stop function of the bumper body


16


provides a shock absorbing effect, to soften a closing movement of a door


11


and to minimize vibration traveling through the frame


10


from the mechanical contact of the door therewith.




For convenience in discussing the assembly hereof, the part of the bumper body shown on the left in the illustration of

FIG. 2

, will be referred to as the inner part thereof, since that portion will be installed inside a vehicle body. Correspondingly, the right part of the bumper body, as shown in

FIG. 2

of the drawings, will be referred to throughout the present specification as the outer part, since this part faces outwardly in the installed configuration of the assembly


14


.




Preferably, the bumper body


16


is formed in a substantially cylindrical or barrel shape, and may have an external helical groove


22


formed as a spiral around the exterior surface thereof, as shown. Where used, the groove


22


is provided to allow the assembly


14


to be threadably and rotatably installed into a circular hole in a vehicle body panel, such as the door frame or jamb


10


. The provision of the external helical groove


22


, on the exterior surface of the bumper body


16


, also provides the further advantage of allowing for easy depth adjustment of the assembly


14


in the door jamb


10


after installation, and also, advantageously, allows for simultaneous adjustment of the door stop and switch functions of the assembly


14


.




The bumper body


16


has a recess or hollow chamber


20


formed centrally therein for receiving and holding the switch


18


. In the embodiment of

FIG. 2

, the hollow chamber


20


passes entirely through the bumper body to form a substantially cylindrical passage therethrough.




An internal annular groove


21


may, optionally, also be provided inside the interior of the bumper body, as shown, to receive and retentively hold the switch


18


therein, and to also receive an outer peripheral edge of the cover member therein, allowing it to protectively and sealingly cover the switch. In a particularly preferred embodiment of the invention, the bumper body


16


includes a retaining bead


23


which extends inwardly into the annular groove


21


, as shown.




Preferably, the bumper body


16


has a thickened center section


25


adjacent the internal groove, to provide added strength and stability thereto.




The Switch




As previously indicated, the switch


18


fits inside the hollow chamber


20


of the bumper body


16


. The switch


18


is shaped to conform to the shape of the chamber


20


, and includes a hollow case


24


, which acts as a housing for other parts of the switch. The case


24


is formed of a non-conductive plastic, and is housed within the hollow chamber


20


of the bumper body


16


, as shown. The case


24


is preferred to include a centrally located, integrally cast anchor pin


40


on the floor thereof, as shown.




The switch


18


has a first contact


26


disposed in the case


24


, which is affixed thereto by gluing, by a rivet, or by any other suitable fixed connection. In the preferred embodiment, the first contact


26


is provided by a metal bracket


28


. In the depicted embodiment, the metal bracket


28


includes a first flat section


30


, a transverse flange


32


which is integrally formed with the first flat section and which extends therefrom at substantially a right angle, and an inwardly projecting collar


34


attached to the top of the first flat section. However, the inwardly projecting collar need not be electrically conductive, and may be formed as a separate piece from the bracket, out of a separate material, so long as it is fixedly attached thereto. The transverse flange


32


of the metal bracket


28


fits into the internal annular groove, as shown, and helps to retain the switch


18


in place inside the bumper body


16


. As an equivalent alternative to the use of the transverse flange


32


on the bracket, instead, the case


24


may include an integrally formed right-angle collar (not shown).




The switch also includes a second contact


27


disposed in the case


24


and spaced apart from the first contact


26


. It is necessary that the second contact


27


be situated farther inside the bumper body


16


than the first contact


26


, so that the contacts stay out of communication with one another until a bridge spring


50


is at the outer extension of its travel in the case


24


.




The switch


18


also includes at least one, and preferably two connectors


57


,


58


in the plug end


54


of the case


24


, for connecting to an electrical circuit. Suitable wires, metal tape, or other conventional electrical connection means are provided attached to the first and second contacts


26


,


27


, respectively, and the respective electrical connectors are also connected to the respective connectors


57


,


58


at the plug end


54


of the case


24


.




The switch


18


also includes an actuator portion for extending outwardly from the outer end of the bumper body


16


and for operatively engaging an edge of a vehicle door


11


. The actuator portion may be provided by an outer end of a push rod member


36


, which is slidably centrally disposed in the case


24


for movement therein. The push rod member


36


is preferably formed from a strong plastic material. In the depicted embodiment, the push rod member


36


includes a center post


38


extending inwardly into the case, opposite the central anchor pin


40


in the case


24


. The push rod member


36


also includes a hollow sleeve


42


which surrounds the center post


38


and which is spaced apart therefrom.




The sleeve


42


and the center post


38


define a substantially cylindrical hollow space


46


therebetween. A coil spring


48


is placed inside the switch


18


, between the push rod member


36


and the anchor pin


40


. Opposed ends of the coil spring


48


surround the center post


38


and the anchor pin


40


, respectively, and accordingly, the coil spring


48


, when compressed in the housing, exerts an outward biasing force on the push rod member


36


.




The innermost part of the sleeve


42


flares outwardly to form an expanded diameter portion


44


. The expanded diameter portion


44


of the push rod member


36


acts as a stop member to retain the push rod member below the inwardly projecting collar


34


of the metal bracket


28


, since the collar


34


substantially surrounds the push rod member


36


, and since the expanded diameter portion of the push rod member is too large to pass therethrough.




The switch


18


also includes a metallic bridge spring


50


which is disposed within the substantially cylindrical hollow space


46


, external to the coil spring


48


. The metallic bridge spring


50


acts to bridge the distance between the first contact


26


and the second contact


27


, when the push rod member


36


is at the outermost extent of its travel, in the position shown in FIG.


2


. When the bridge spring interconnects the first and second contacts


26


,


27


, electrical continuity is provided therebetween.




When the assembly


18


is plugged into an electrical circuit, and the door


11


is opened, the coil spring


48


pushes the push rod member


36


outwardly from the case until the bridge spring interconnects the first and second contacts


26


,


27


. At that point, the circuit is completed and electrical power flows therethrough to perform work, such as, for example, to light an interior dome lamp and illuminate the passenger compartment of a vehicle.




The Cover Member




Also in the preferred embodiment of the present invention, a flexible, water-resistant cap or cover member


15


is provided to cover and protect the switch


18


. The cover member


15


, where used, may be made of rubber or a suitable elastomer which may be the same as, or different than, the material used for the bumper body


16


. The cover member


15


, according to the most preferred embodiment of the invention, has a raised peripheral ridge


53


extending continuously around the outer edge thereof, for sealing placement behind the retaining bead


23


of the bumper body. The tip end


55


of the cover member


15


is made thicker than the remainder thereof, to provide an extended wear surface for contacting an edge of the vehicle door


11


.




Overview of the Second Preferred Embodiment




Referring now to

FIG. 3

, a combined doorstop and switch assembly


114


, in accordance with a second preferred embodiment of the present invention, includes a housing member


116


for attaching to a vehicle body panel


10


, and a switch


118


which is housed within, and integrally secured to the housing member


116


. The housing member


116


, in this embodiment, combines the functions of the previously discussed bumper body


16


and protective cap or cover member


15


into a single, integrally molded part. Each of these components of the assembly


114


will be discussed in further detail below.




The Housing Member




The housing member


116


is formed of a resilient yet semi-rigid material, which may be rubber or a durable elastomer. A preferred material for the housing member is an EPDM (ethylene propylene diene monomer) elastomer. The housing member


116


is of a strength and thickness sufficient to make it durable enough to serve as a door stop, or energy absorbing damper, when in place in a vehicle. Preferably, the housing member


116


has a thickened center section


125


below the internal groove, to provide added strength and stability thereto.




Preferably, the main body of the housing member


116


is formed in a substantially cylindrical or barrel shape, and may have an external helical groove


122


formed as a spiral formed around the exterior surface thereof, as shown. Where used, the groove


122


is provided to allow the assembly


114


to be threadably and rotatably installed into a circular hole in a vehicle body panel, such as the door frame or jamb


10


. The provision of the external helical groove


122


, on the exterior surface of the housing member


116


, also provides the further advantage of allowing for easy depth adjustment of the assembly


114


in the doorjamb


10


after installation.




The housing member


116


has a recess or hollow chamber


120


formed centrally therein, for receiving and holding the switch


118


. In the embodiment of

FIG. 3

, the hollow chamber


120


passes only part of the way through the housing member to form a substantially cylindrical recess therein.




The switch


118


is pressed into the chamber


120


from the interior side of the housing member


116


. The housing preferably has a raised ridge


121


formed on the interior thereof to retain the switch


118


within the chamber


120


.




In the embodiment of

FIG. 3

, the housing member


116


further includes a flexible, water-resistant cap or cover member


115


to cover and protect the switch


118


. The cover member


115


is integrally formed with the main body of the housing member


116


. The cover member


115


is made of rubber or a suitable elastomer which may be the same as, or different than, the material used for the housing member


116


. The tip end


155


of the cover member


115


is made thicker than the remainder thereof, to provide an extended wear surface for contacting an edge of the vehicle door


11


.




The Switch




As previously indicated, the switch


118


fits inside the hollow chamber


120


of the housing member


116


. The switch


118


functions substantially similarly to the previously described switch


18


. The switch


118


is shaped to conform to the shape of the chamber


120


, and includes a hollow case


124


, which houses other parts of the switch. The case


124


is formed of a non-conductive plastic. The case


124


is preferred to include a centrally located, integrally cast anchor pin


140


on the floor thereof, as shown.




The switch


118


has a first contact


126


disposed in the case


124


, which is affixed thereto by gluing, by a rivet, or by any other suitable fixed connection. In the preferred embodiment, the first contact


126


is provided by a metal bracket


128


. In the embodiment of

FIG. 3

, the metal bracket


128


includes a first flat section


130


and an inwardly projecting collar


134


attached to the top of the first flat section. However, the inwardly projecting collar


134


need not be electrically conductive, and may be formed as a separate piece from the bracket


128


, out of a separate material, so long as it is fixedly attached thereto.




The switch also includes a second contact


127


disposed in the case


124


and spaced apart from the first contact


126


. It is necessary that the second contact


127


be situated farther inside the housing member


116


than the first contact


126


, so that the contacts stay out of communication with one another until a bridge spring


150


is at the outer extension of its travel in the case


124


.




The switch


118


also includes at least one, and preferably two connector plugs


157


,


158


in the plug end


154


of the case


124


, for connecting to an electrical circuit. Suitable wires, metal tape, or other conventional electrical connection means are provided attached to the first and second contacts


126


,


127


, respectively, and the respective electrical connection means are also connected to the respective connector plugs


157


,


158


at the plug end


154


of the case


124


.




The switch


118


also includes an actuator portion for extending outwardly from the outer end of the housing member


116


and for operatively pressing an outermost tip


155


of the cover


115


against an edge of a vehicle door


11


. The actuator portion may be provided by an outer end of a push rod member


136


, which is slidably centrally disposed in the case


124


for movement therein. The push rod member


136


is preferably formed from a strong plastic material. In the embodiment, the push rod member


136


includes a center post


138


extending inwardly into the case, opposite the central anchor pin


140


in the case


124


. The push rod member


136


also includes a hollow sleeve


142


which surrounds the center post


138


and which is spaced apart therefrom.




The sleeve


142


and the center post


138


define a hollow space


146


therebetween. A coil spring


148


is placed inside the switch


118


, between the push rod member


136


and the anchor pin


140


. Opposed ends of the coil spring


148


surround the center post


138


and the anchor pin


140


, respectively, and accordingly, the coil spring


148


, when compressed in the housing, exerts an outward biasing force on the push rod member


136


.




The innermost part of the sleeve


142


flares outwardly to form an expanded diameter portion


144


. The expanded diameter portion


144


of the push rod member


136


acts as a stop member to retain the push rod member below the inwardly projecting collar


134


of the metal bracket


128


, since the collar


134


substantially surrounds the push rod member


136


, and since the expanded diameter portion


144


of the push rod sleeve


142


is too large to pass therethrough.




The switch


118


also includes a metallic bridge spring


150


which is disposed within the hollow space


146


, external to the coil spring


148


. The metallic bridge spring


150


acts to bridge the distance between the first contact


126


and the second contact


127


, when the push rod member


136


is at the outermost extent of its travel, in the position shown in FIG.


3


.




When the bridge spring


150


interconnects the first and second contacts


126


,


127


, electrical continuity is provided therebetween.




When the switch


118


is plugged into an electrical circuit, and the door


11


is opened, the coil spring


148


pushes the push rod member


136


outwardly from the case


124


until the bridge spring


150


interconnects the first and second contacts


126


,


127


. At that point, the circuit is completed and electrical power flows therethrough to perform work, such as, for example, to light an interior dome lamp and illuminate the passenger compartment of a vehicle.




Use of the Assembly




The use of the assembly will be described in relation to the embodiment of FIG.


2


. When the apparatus


14


according to the invention is installed in a vehicle, and a vehicle door (not shown) is closed thereagainst, two things happen. First, the door presses the push rod member


18


inwardly into the case against the force of the spring


48


. This moves the bridge spring


50


away from the first contact


26


to open the circuit, most preferably to shut off the vehicle interior lamp (not shown).




Secondly, when the outer end of the push rod member


18


is pressed into the case


24


beyond a certain point, the leading edge of the door comes in contact with the outer edge


56


of the bumper body


16


. The bumper body


16


compresses somewhat to absorb and dampen the force of the closing door.




The combined assembly


14


according to the present invention provides the added advantage that the depth of the door stopper bumper body


16


, and the operative position of the door-activated switch


18


, may be simultaneously adjusted in a single operation, by spinning the assembly


14


in place in a vehicle body panel until the bumper body


16


is correctly oriented to function as a door motion damper. When the bumper body is adjusted to the correct depth in the body panel, the switch is advantageously set to the correct orientation thereof, without requiring a separate adjustment as was previously necessary with separate doorstop and switch devices. Using the embodiment of

FIG. 3

is substantially identical to using the first embodiment as herein described.




Although the present invention has been described herein with respect to a preferred embodiment thereof, the foregoing description is intended to be illustrative, and not restrictive. Those skilled in the art will realize that many modifications of the preferred embodiment could be made which would be operable.




One possible modification is that the cover member


15


could be deleted and instead, a large resilient rubber button (not shown) could be attached directly to the outermost end of the push rod member, to further combine the functions of the assembly. Another possible modification is to make the bumper body box-shaped, instead of cylindrical.




All such modifications, which are within the scope of the appended claims, are intended to be within the scope and spirit of the present invention.
