## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a divisional application co-pending U.S. Provisional Patent Application Ser. No. 61/288,279, filed on Dec. 19, 2009, which is incorporated herein in its entirety.


FIELD OF THE INVENTION
The present invention relates to a vehicle security system, and more particularly, a door management system comprising a deadbolt door locking system and a roll up door automated door mechanism, each comprising an external emergency release allowing release of the lock should a failure occur in either mechanism.
BACKGROUND OF THE INVENTION
The invention pertains to a cargo vehicle security system comprising a deadbolt door locking system for each of a single door and a double door. The cargo vehicle security system further comprising an automated door opening system for opening a roll up door.
An overhead door opening system for use in conjunction with a roll up cargo door is known. The implementation has a variety of configurations. Each of the systems are limited should the overhead door opening system fail. The configuration of most cargo vehicles provides a single access to the cargo area, that being the roll up cargo door. Should the overhead door opening system fail, the system locks the user from accessing the cargo area.
The overhead door opening system allows the door to move vertically while the vehicle is traveling and passes across bumps or other vibration introducing features along the path of travel. The play in the overhead door opening system allows the cargo door to jump up and down, allowing smaller items to slide under the door, cause potential damage to the door or door opening system, and the like. The noise can be distracting to the driver or other occupants of the vehicle.
Several door locking deadbolt systems are known. Each of the deadbolt configurations secures the door to a vehicle frame member. The deadbolt and actuator can be secured to the door, with the deadbolt pin being moveably configured to engage with the frame member. Alternately, the deadbolt and actuator can be secured to the frame member, with the deadbolt pin being moveably configured to engage with the vehicle door. Should the locking system fail, leaving the deadbolt engaged and the door locked in a closed position. A failure would keep a driver from accessing the interior of the vehicle. A failure during an accident would keep rescue workers from accessing the occupants of the vehicle via the doors.
Accordingly, there remains a need in the art for a device that secures a vehicle, while allowing access to the secured compartments should the securing system fail.

Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
The present invention integrates an automated door opening assembly 120 into a cargo vehicle 100. The cargo vehicle 100 includes commonly known features, such as a vehicle cab 102 and a cargo trailer 110 as presented in the exemplary illustration of FIGS. 1 and 2. The vehicle cab 102 is accessible via a vehicle door 104. A door window 106 is integrated into the vehicle door 104 providing visibility for the occupants. Contrarily, the door window 106 provides an easy access point for a criminal to obtain unauthorized entry into the vehicle cab 102. The cargo trailer 110 is accessible via a trailer access door 112; the trailer access door 112 commonly being a roll up door comprising a plurality of trailer roll up door panels 114. The plurality of trailer roll up door panels 114 is assembled via a series of door panel hinges 115. The trailer access door 112 comprises a series of door wheels 116 engaged in a roll up door track 118. The automated door opening assembly 120 maintains the trailer access door 112 at a fixed position, preferably either closed (as shown) or open (as understood). The automated door opening assembly 120 comprises an automated opener or drive motor 122 in communication with an opener track and drive assembly 124 (the drive assembly may alternately be referred to as a linear motion control assembly) for moveably positioning a linkage arm to door opening carriage or track engaging assembly 128. The drive assembly can be a screw drive, a chain drive, a cable drive, and the like, including the interface provided between the opener motor 122 and a linear motion means. An opener linkage arm 126 extends between and couples the linkage arm to track engaging assembly 128 and the trailer access door 112 for opening/closing the trailer access door 112, as well as maintaining the trailer access door 112 at a position. The automated opener motor 122 drives the opener track and drive assembly 124. The linkage arm to track engaging assembly 128 is engaged with the drive components of the opener track and drive assembly 124. The linkage arm to track engaging assembly 128 is connected to the trailer access door 112 via the opener linkage arm 126. The automated opener motor 122 operates and moves the drive components of the opener track and drive assembly 124, which drives the position of the linkage arm to track engaging assembly 128. The resulting motion opens or closes the trailer access door 112 accordingly. When the automated door opening assembly 120 is not in operation, the automated opener motor 122 remains stationary, thus maintaining the trailer access door 112 in position. The opener track and drive assembly 124 can utilize a chain drive, a cable dive, a screw drive, and the like. The automated opener motor 122 can operate via AC or DC current. The preferred embodiment utilizes DC current, thus avoiding the need for an inverter.
The trailer access door 112 is generally an assembly comprising a plurality of trailer roll-up door panels 114, as best illustrated in FIG. 2. Each of the trailer roll up door panel 114 utilizes a pair of door wheels 116 located on each of the outer edges of the trailer roll up door panel 114, preferably proximate the corners. A keypad remote 170 or a remote operation transmitter 172 can be used for operating the automated door opening assembly 120. The user can enter a code and any required instructions into the keypad remote 170. Upon verification of the entered information, the keypad remote 170 transmits an activation signal to a receiver in the automated opener motor 122. The automated opener motor 122 acts accordingly. Similarly, the user simply depresses an actuation button on the remote operation transmitter 172 to transmit a signal to the receiver in the automated opener motor 122. The remote operation transmitter 172 allows the driver to retrieve items from inside the cargo trailer 110, begin walking away and automatically lower the trailer access door 112. As the driver approaches the cargo vehicle 100, the user can utilize the remote operation transmitter 172 to open the trailer access door 112 such that the trailer access door 112 is opened when the driver arrives. An opener release handle 140 allows the driver to release the linkage arm to track engaging assembly 128 from the opener track and drive assembly 124, providing access to the cargo trailer 110 should the automated door opening assembly 120 fail. An automated locking assembly 160 can be provided to limit the motion of the trailer access door 112 as desired. Alternately, the remote operation transmitter 172 can be a proximity type device, whereby the system automatically detects when the remote operation transmitter 172 is within range and subsequently opens the door. When the system detects the remote operation transmitter 172 is out of range, the system begins a delay process to ensure the remote operation transmitter 172 is out of range. Upon verification that the remote operation transmitter 172 is out of range, the system closes the door.
Details of an exemplary emergency release system are presented in FIGS. 3 through 6 and 14. An engagement release lever 130 is used to engage and release the linkage arm to track engaging assembly 128 with the opener track and drive assembly 124. The linkage arm to track engaging assembly 128 includes a drive member mating component 132 operated by the engagement release lever 130. The engagement release lever 130 includes a mating component cam 131 that repositions the drive member mating component 132 in accordance with a drive member mating component engaging motion 136. In an engaged configuration (shown in solid lines), the mating component cam 131 engages drive member mating component teeth 134 of the drive member mating component 132 with a drive member 138 located within the opener track and drive assembly 124. In a disengaged configuration, (shown in broken lines), the mating component cam 131 disengages drive member mating component teeth 134 from the drive member 138. The linkage arm to track engaging assembly 128 comprises the components providing a removably engaging coupling, including the drive member mating component 132 in operational communication with the engagement release lever 130. The exemplary embodiment illustrates a commonly known screw drive configuration. It is understood that the system can be adapted to any drive configuration. The opener release handle 140 engages with the engagement release lever 130 via a release cable 144. The release cable 144 can be a cable, a linkage, or any other form of intermediary means, generally referred to as a release control element. The release cable 144 can be actuated via a cam such as a release operable arm 142 attached to the opener release handle 140. When the driver rotates the opener release handle 140 into a release position opener release handle 140′ (FIGS. 4 and 6), the release operable arm 142 is rotated into a release position release operable arm 142′, pulling the release cable 144′. The release cable 144′ (released configuration) positions the engagement release lever 130′ in the respective released configuration. The opener release handle 140 can include a lock 146 to ensure against disengagement of the linkage arm to track engaging assembly 128 by an unauthorized party. It is understood that any form factor for a release mechanism that is operable from the exterior of the cargo trailer 110 is desirable. Other exemplary means includes a simple pull ring. The pull ring can be provided positioning a locking bar through the ring.
A slip linkage bracket assembly 150 can be integrated into the automated door opening assembly 120. The slip linkage bracket assembly 150 allows the opener linkage arm 126 to move between a lockdown position referenced as 126′ and a door lift position referenced as 126. The slip linkage bracket assembly 150 is fabricated having a linkage arm bracket 152 with a vertical slot 154 arranged vertically therethrough. A linkage pin 156 is disposed through the engaging end of the opener linkage arm 126. The linkage pin 156 is slideably positioned through the vertical slot 154 of the linkage arm bracket 152. A linkage biasing member 158 (the upper and lower portions being illustrated with the center removed for presentation purposes) can be assembled maintaining the opener linkage arm 126 in a raised position. The slideable engagement between the opener linkage arm 126 and the linkage arm bracket 152 allows the automated door opening assembly 120 to partially move independently of the trailer access door 112. This difference in movement can allow for a variety of operations. A first option would be the inclusion of an automated locking assembly 160. The automated locking assembly 160 provides a deadbolt lock by automatically engaging a deadbolt locking bar 162 with a receiving aperture within the roll up door track 118 to create a mechanical lock between the trailer access door 112 and the roll up door track 118. A locking bar bracket 164 guides and maintains the orientation of the deadbolt locking bar 162. A locking bar biasing member 166 ensures the locking assembly control cable 168 remains in a tensile state. As the opener linkage arm 126 moves to an opening position, referenced as 126′, the opener linkage arm 126 pulls the locking assembly control cable 168 upwards placing the linkage pin 156 in a position against an upper edge of the vertical slot 154, referenced as 156′. The applied tension to the locking assembly control cable 168 causes the deadbolt locking bar 162 to disengage from the roll up door track 118. A cable expansion assembly 169 can be provided along the locking assembly control cable 168 to compensate for tolerances, shock, and the like. The exemplary cable expansion assembly 169 is a biased expansion assembly. When the trailer access door 112 is lowered, the opener linkage arm 126 removes the tension from the locking assembly control cable 168, thus the locking bar biasing member 166 biases the deadbolt locking bar 162 to engage with the aperture of the roll up door track 118. An emergency release handle (similar to the opener release handle 140) can be integrated with the locking assembly control cable 168 should the automated door opening assembly 120 or other operable element fail. It is understood that the sliding engaging design (as shown) can alternately be operable via a pivotal motion to engage and disengage the locking bar from the track. The locking bar would pivot between a locked and an unlocked orientation.
A remote deadbolt assembly 180, as illustrated in FIGS. 9 and 10, can be integrated as an alternative to the automated locking assembly 160. The remote deadbolt assembly 180 includes a deadbolt actuator 182 for operating a deadbolt pin 184. The deadbolt pin 184 is slideably assembled through a deadbolt bracket 185, wherein the deadbolt bracket 185 provides support and registration of the deadbolt pin 184 to a deadbolt receiving aperture 186 through the roll up door track 118. The deadbolt actuator 182 moves an actuating arm 183. A linkage arm 188 provides connectivity between the actuating arm 183 and the deadbolt pin 184. The deadbolt pin 184 is inserted above a contacting surface of the door wheels 116 at a distance identified as gap “G”. The gap “G” allows an unauthorized party to move the trailer access door 112 upwards allowing a proximity alarm sensor 198 to change state. An emergency release cable 190 is included, as a component of the remote deadbolt assembly 180 allowing a party to disengage the deadbolt pin 184 from the deadbolt receiving aperture 186 should the deadbolt actuator 182 or another component fail. A release ring 192 can be provided at a distal end of the emergency release cable 190, aiding the party in pulling the emergency release cable 190. At least one redirecting element 194 can be utilised to redirect the emergency release cable 190 as desired to properly disengage the deadbolt pin 184 from the deadbolt receiving aperture 186. The release ring 192 can be secured via a locking bar to ensure against unauthorized disengagement.
The trailer access door 112 is one of several potential access means to the cargo vehicle 100. Security is required at all access means to properly secure the cargo vehicle 100. A two-door security configuration is presented in FIG. 11, with exemplary detailed embodiments being presented in FIGS. 12 and 13. An exemplary vehicle door assembly 200 demonstrates several potential locking means for securing a primary door 202 and a secondary door 204. Each door 202, 204 generally includes a door window 206, which unfortunately, provides an access means for an unauthorized party. The unauthorized party could break the door window 206, allowing the party to unlock the door and simply open the primary door 202 via a door handle 208. The primary door 202 overlaps a mating edge of the secondary door 204, thus only requiring a means for securing the primary door 202.
The vehicle door assembly 200 can be secured via either a door-to-door deadbolt assembly 220 or a door to frame deadbolt assembly 230. The door-to-door deadbolt assembly 220 comprises a configuration similar to the remote deadbolt assembly 180 (FIGS. 9 and 10). The door-to-door deadbolt assembly 220 includes a deadbolt actuator 222 for operating a deadbolt pin 224. The deadbolt pin 224 is slideably assembled through a deadbolt bracket 225, wherein the deadbolt bracket 225 provides support and registration of the deadbolt pin 224 to an aperture provided in the adjacent door (or doorframe for a single door). The deadbolt actuator 222 moves an actuating arm 223. A linkage arm 228 provides connectivity between the actuating arm 223 and the deadbolt pin 224.
In an alternate embodiment, the door to frame deadbolt assembly 230 engages the primary door 202 with a doorframe 210, securing the door in a closed position. The door to frame deadbolt assembly 230 includes a deadbolt actuator 232 and a deadbolt pin 234. The deadbolt actuator 232 adjusts the deadbolt pin 234 to engage and disengage with a deadbolt receiving aperture 238 through the doorframe 210. The door to frame deadbolt assembly 230 can include a deadbolt assembly mounting bracket 231 for attaching the deadbolt actuator 232 to the primary door 202. Power is provided to the deadbolt actuator 232 via a power source 260. Power is transferred between the various components via a series of electrical cables 266. The components can be connected to a ground connection 264, such as the chassis of the cargo vehicle 100, which is commonly used. An optional time delay 262 can be provided between the power source 260 and the deadbolt actuator 232, allowing the user time to exit the vehicle prior to actuation of the deadbolt actuator 232. The door to frame deadbolt assembly 230 can be operated via a keypad remote 170 or remote operation transmitter 172 as previously described. Should a component fail in the door to frame deadbolt assembly 230, the operator would be denied access to the cargo vehicle 100. An emergency release cable 240 is secured directly or indirectly (such as via a release arm 236) to the deadbolt pin 234 allowing the user the ability to disengage the deadbolt pin 234 from the deadbolt receiving aperture 238 as needed. A release ring 242 can be provided at a distal end of the emergency release cable 240 for aiding a party in disengaging the deadbolt pin 234 from the deadbolt receiving aperture 238. The emergency release cable 240 can be guided through at least one redirecting element 244 to provide proper operative flow. Although a cable is illustrated, it is understood that any mechanical configuration can be utilized, such as a cantilever, a series of linkages, and the like. The release ring 242 can be secured via a locking bar to ensure against unauthorized disengagement.
An inertial release mechanism 250 can be integrated with the door to frame deadbolt assembly 230 as illustrated in FIG. 13. The inertial release mechanism 250 disengages the deadbolt pin 234 by driving the release arm 236 to a position referenced as 236′. The inertial release mechanism 250 utilizes an inertial release actuator 256 positioned on or within a supporting surface (not shown). An inertial release cable 252 is attached between the inertial release actuator 256 and the release arm 236. The inertial release cable 252 can be routed through one or more inertial release cable controls 254 as needed to adequately route the inertial release cable 252. The inertial release actuator 256 moves from a set position to an inertial releasing position referenced as 256′. During an abrupt change in motion, the inertial release actuator 256 is repositioned. The inertial release actuator 256 would be of a sufficient mass to apply a tension to the inertial release cable 252, thus moving the release arm 236. The inertial release mechanism 250 can be combined with the emergency release cable 240. It is understood that an emergency release system can be integrated with an airbag activation sensor.
The above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the invention. Many variations, combinations, modifications or equivalents may be substituted for elements thereof without departing from the scope of the invention. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all the embodiments falling within the scope of the appended claims.
