## Background
This application claims the benefit of U.S. Patent Application No. 62/180,952, filed on Jun. 17, 2015, which is herein incorporated by reference.


FIELD OF THE INVENTION
This invention relates in general to vehicle storage devices.
BACKGROUND OF THE INVENTION
Pickup trucks comprise a cab and a bed. The bed may comprise raised sides with an open top. It is known to provide tool boxes for use in a bed of a pickup truck.
Many tool boxes for use in the bed of a pickup truck require the user to bend down to reach down in the tool box to retrieve items from the tool box. While the storage of tools within the tool box in the bed of a pickup truck may be convenient for transport, tools may not be conveniently located for easy removal from or storage within the tool box.
U.S. Pat. No. 5,303,969 (the '969 patent) and U.S. Pat. No. 7,182,177 (the '177 patent) disclose a tool box for locating over a wheel well of a truck bed. A jack is provided to move the tool box between a raised and a lowered position. However, the devices of the '969 patent and the '177 patent do not provide a housing that protects the jack from the environment and from materials that may be loaded into the bed of the truck.
U.S. Pat. No. 6,626,479 (the '479 patent) discloses a tool box that extends across the bed of a truck. A jack is provided to move the tool box from a lowered position to a raised position. However, the device of the '479 patent does not provide a housing that protects the jack components from the environment and from materials that may be loaded into the bed of the truck. Further, the device of the '479 patent provides long tubes for housing a portion of the lift mechanism and the tubes interrupt long vertical spaces of the container.
U.S. Patent App. Pub. No. 2011/0284602 (the '602 publication) discloses a tool box for a bed of a truck. Jacks raise and lower the tool box. However, the device of the '602 publication does not provide a housing that protects the jack components from the environment and from materials that may be loaded into the bed of the truck.
The devices of U.S. Pat. Nos. 8,636,182 and 6,929,303 do not provide a housing that protects the jack components from the environment and from materials that may be loaded into the bed of the truck.
U.S. Patent App. Pub. 2010/0051662 and U.S. Pat. No. 4,936,624 disclose truck tool boxes having a raisable portion. However, the raisable portions do not raise completely out of the tool box nor do they raise in a level manner. Each of these devices comprise a tilting lift mechanism, which has the disadvantage of causing the contents to slide to the back of the raisable portion away from the user. This makes it hard to maintain organization within the raisable portion and more difficult for the user to reach the desired items in the raisable portion.
The present inventor recognized the need for an improved lifting container for a vehicle.
The present inventor recognized the need for a lifting container that allows the user to deposit and remove items from a position more convenient for the user. The present inventor recognized the need for a lifting container that provides a housing for the lift mechanism to protect the mechanism from the environment and contents that may be loaded into the bed of the truck. The present inventor recognized the need for a lifting container that lifts vertically from an exterior housing so that the contents in the lifting container are not shuffled by tilting.
SUMMARY OF THE INVENTION
A lift storage device for a truck bed is disclosed. In one embodiment, the device comprises an exterior housing, an interior container, and a scissor lift mechanism.
The exterior housing comprises sidewalls, a lid, a left wing, and a right wing. The left wing is configured to rest on a left side rail of the truck bed and the right wing is configured to rest on the right side rail of the truck bed so that the exterior housing extends across the truck bed.
The scissor lift mechanism is located within the exterior housing and is operatively connected to the interior container. The scissor lift mechanism comprises a raised position and a lowered position. The interior container is within the exterior housing when the scissor lift mechanism is in the lowered position. The interior container is at least partially located outside the exterior housing when the scissor lift mechanism is in the raised position. The scissor lift mechanism maintains the interior container in the same orientation when the scissor lift mechanism is in the raised position and when the scissor lift mechanism is in the lowered position.
A drive mechanism is operatively connected to the scissor lift mechanism to drive the scissor lift mechanism between the lowered position and the raised position.
In some embodiments, the interior container comprises a plurality of drawers located on a left side, a right side, and/or a front face of the interior container.

DETAILED DESCRIPTION
The following description is presented to enable any person skilled in the art to make and use the invention. For the purposes of explanation, specific nomenclature is set forth to provide a plural understanding of the present invention. While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.
FIG. 1 shows a storage device 20 for a truck. The storage device 20 mounted in the bed 10 of the truck. The storage device 20 is mounted so the length of the storage device extends across the bed of the pickup truck between a first side rail 13 and a second side rail 14 of the bed 10 adjacent the front boundary of the bed 10 and adjacent the cab 17 of the truck.
The storage device 20 comprises an exterior container 22, an interior container 41, and a lift mechanism 131. The lift mechanism 131 is configured to raise and lower the interior container 41 relative to the exterior container 22.
The exterior container 22 comprises a base 24, a top portion 26, and a lid 40. The base 24 comprises a front wall 106, a left side wall 112, a right side wall 110, and a back wall 108. The top portion 26 extends from the base.
The top portion 26 comprises a left wing 28 and a right wing 30. The left-wing 28 is configured to be located over the left side rail 13 of the bed 10. The right wing 30 is configured to be located over the right side rail 14 of the bed 10. The left and right wings support the exterior container on the respective side rails of the bed above the bed floor 9. In some embodiments, the exterior container may rest on the bed floor as well.
Left clamp 29 and right clamp 31 extend from the respective left wing and right wing and under the respective left rail 13 and right rail 14 to secure the exterior container 22 to the bed rails by clamping force about the rails 13 and 14. The clamping force prevents the movement of the exterior container relative to the truck bed.
As shown in FIG. 5, the top portion 26 comprises a front wall 114, a back wall 116, a left side wall 118, and a right side wall 120. In some embodiments, such as the embodiment shown in FIG. 1, the top portion is wider than the base in all horizontal directions. Therefore, the front wall 114 is positioned rearward of the front wall 106. The back wall 116 is positioned forward relative to the back wall 108. The left side wall 118 is spaced leftward relative to the left side wall 112. The right side wall 120 is spaced rightward relative to the right side wall 110. Therefore the horizontal area in the top portion 26 is greater than the horizontal area in the base 24. In some embodiments, the top portion is wider only in the right and left horizontal directions, but not in the front and rear horizontal directions.
As shown in FIG. 1, a vertical depth of the base 24 is greater than the vertical depth of the top portion 26. Therefore, more of the exterior container 22 is located below the top of the side rails 13 and 14 than is located above.
The lid 40 is attached to the base by a hinge. The hinge connects to a first side of the lid. The hinge also connects to an exterior surface of the back wall 116 of the top portion 26. The hinge allows the lid to pivot between an open position as shown in FIGS. 1 and 5 and a closed position (not shown) where the lid rests on or adjacent the top edge 27 of the top portion 26. When the lid is in the closed position, the exterior housing provides an enclosed space containing the interior container 41 and the lift mechanism 131.
When the lid is in the closed position, the male elements 36, 38 engage with the female latches 32, 34 to releasably secure the lid in the closed position. The female latches 32, 34 comprise handles which when pulled upward released the latch mechanism and allow the male elements 36, 38 to withdraw from the female latches.
As shown in FIGS. 2 and 3, the lid may comprise a perimeter skirt 62, 63, 64, 65, which extends away from the main portion 67. The right and left sides of the lid comprise a right cylinder mount 66a and a left cylinder mount 66b, respectively. The mounts 66a, 66b may be plates extending from the main portion 67 and comprising an aperture for receiving a pivotable attachment to a right lift cylinder 68 and a left lift cylinder 75, respectively. At an end 73a (right side not shown) opposite the attachment to the lid, the lift cylinder 75 pivotal attaches to a mounting tab 69 (right side not shown) of the top portion 26 which extends from the back wall 116.

The drive gear is meshed with the transfer gear and drives the transfer gear. The transfer gear is a meshed with a driven gear. The driven gear is fixed to one end of the threaded shaft 257. Therefore the motor, via the gearing, drives the threaded shaft 257 to rotate. In some embodiments, the motor as a first function to the drive output shaft to rotate in a first direction and a second function to drive the output shaft to rotate in an opposite second direction. In some embodiments, the first direction causes the scissor lift to rise and the second direction causes the scissor lift to lower. In some embodiments, the motor is an electric motor. In some embodiments, the motor directly drives the threaded shaft.
The motor can be connected to a power source, such as a vehicle battery, by a cable 219. In some embodiments, the vehicle battery or other power source is a 12 volt power source and the motor is adapted to operate from a 12 volt power source. In some embodiments, the vehicle or other power source is adapted to provide 110 volt power and the motor is adapted to operate from a 110 volt power source. The cable 219 may comprise a control switch 60. The control switch provides three positions, a raise position, a lower position and a neutral position. When in the raise position the switch causes power to be provided to the motor to cause the motor to rotate in the first direction. When in the lower position, the switch causes the power to be provided to the motor to cause the motor to rotate in a second direction opposite the first direction. In the neutral position the power switch provides no power to the motor so that the motor does not turn and the lift mechanism does not raise or lower.
The switch 60 may be located at the front of the exterior container as shown in FIGS. 1 and 5. In some embodiments, the switch 60 may be located at either the left or right side of the exterior container so that it is readily available adjacent the doors of the truck cab. In some embodiments, the switch can be located at 126 in FIG. 5 and at the same location on the opposite side. In some embodiments, two switches for controlling the motor and the lift mechanism are provided, one at each of the left and right sides of the exterior container.
While the figures show the switch is in wired communication with the battery and motor, in some embodiments the switch is within a wireless handheld device that is wireless communication with a receiver or transceiver, which is in wired control communication with the motor. Communication between the handheld device and the receiver or transceiver may comprise an authentication function on the handheld device and the receiver or transceiver for ensuring the handheld device is authorized to instruct the receiver or transceiver. Communication between the handheld device and/or the receiver or transceiver may comprise an encryption function on the handheld device and/or the receiver or transceiver for providing encrypted communication between the handheld device and the receiver or transceiver.
In one embodiment, the power is available to the switch only when the vehicle's ignition switch is in the on condition/position. Therefore the lift mechanism can only be operated when the vehicle's ignition switch is in the on condition/position.
The second pivot bracket 272 comprises a cylindrical sleeve 273. The cylindrical sleeve 273 does not have threads that engage the threaded shaft 257. Therefore the threaded shaft rotates freely within the sleeve 273.
When the motor 216 drives the output shaft to rotate in the first direction, the threaded shaft is rotated in the first direction. When the threaded shaft is driven in the first direction the threaded engagement between the threaded shaft 257 and the first pivot bracket 241 causes the first pivot bracket to be drawn towards the second pivot bracket 272. This draws the first upper scissor arm 252 towards the second upper scissor arm 256 and it also draws the first lower scissor arm 258 towards the second lower scissor arm 260. This movement causes the upper support bracket 254 to move away from the lower support bracket 262. As the upper support bracket 254 moves away from the lower support bracket 262 the scissor lift 163 is raised.
When the threaded shaft is not rotated, the lift mechanism will maintain its position and will not raise or lower. This is due to the threaded engagement with the first pivot bracket 241 and the connection to the second pivot bracket.
The lower support bracket 262 is fixed to the pivot bar 222. The pivot bar 222 is operatively connected to the lower frame 144. When the lower frame 144 is supported on the ground or against the floor 104 of the exterior container 22, operating the motor in the first direction will cause the upper support bracket 254 to rise. Since the upper support bracket 254 is operably attached to the scissor mechanism 162, operating the motor in the first direction will cause the scissor mechanism to rise in the direction A of FIG. 9. The upper support bracket 254 will cause the plates 242, 244 to draw upward the scissor mechanism via the plates 242, 244 attachment to the first and second cross plate portions 232, 234 and the first and second cross plate portions attachment to scissor bars 184, 176.
The upper ends of the scissor bars 184, 176 will rise driving upward the bars 180, 186, which raises the platform 140, which raises the upper frame 74. As bars 184, 176 raise upward, the bottom ends of bars 174, 182 are drawn forward in the direction E of FIGS. 8 and 9 within the slide tracks 203, 205. As the bottom ends of the bars 174, 182 are drawn forward in direction E, each of the bars 174, 182 pivot about the respective pivot locations 190, 187. The pivoting drives the upper ends of each of the bars 174, 182 which forces through the pivot locations 204, 202 the bars 188 and 178 upward. As bars 188, 178 or driven upward they drive the platform 140 upward and thereby drive the upper frame 74 upward in the direction A.
When the scissoring mechanism is rising, bar 182 will be rotating and sliding in the direction E within the slide track 205, bar 182 will be pivoting at pivot location 187, and will be moving in an arcing path at pivot location 204 to enable the scissoring mechanism to rise. Similarly, bar 188 will be moving in an arcing path at pivot location 204, will be pivoting at pivot location 189, and will be rotating and sliding in slide track 217 in the direction E.
When the scissoring mechanism is rising, bar 174 will be rotating and sliding within the slide track 203 in the direction E, bar 174 will be pivoting at pivot location 190, and will be moving in an arcing path at top end pivot location 200 to enable the scissoring mechanism to rise. Similarly bar 180 will be moving in an arcing path at pivot location 200, will be pivoting at pivot location 192, and will be rotating and sliding in slide track 215 in the direction E.
When the scissoring mechanism is rising, bar 184 will be rotating at the first end 167, bar 184 will be pivoting at pivot location 187, and will be moving in an arcing path at pivot location 206 to enable the scissoring mechanism to rise. Similarly bar 186 will be moving in an arcing path at point location 206, will be pivoting at pivot location 189, and will be rotating at the first end 213.
When the scissoring mechanism is rising, bar 176 will be rotating at the first end 198, bar 176 will be pivoting at pivot location 190, and will be moving in an arcing path at pivot location 202 to enable the scissoring mechanism to rise. Similarly bar 178 will be moving in an arcing path at pivot location 202, will be pivoting at pivot location 192, and will be rotating at the top end 214.
As the scissor lift rises, it will rotate at the pivot bar 222 in the direction C shown in FIG. 9. The pivot bar 222 will rotate within the sleeves 170, 172. As the scissor lift rises, the plates 242, 244 pivot about the pin 253 in the direction C.
As the scissor mechanism raises, bars 174, 182 will rotate and slide in the direction E within the respective slide tracks 203, 205. Bars 180, 188 will rotate and slide in the direction E within the respective slide tracks 215, 217. Therefore the lower ends of bars 174, 182 will move toward the bottom ends of bars 176, 178 respectively. The upper ends of bars 180, 188 will move toward the upper ends of bars 178, 186. As the scissoring mechanism raises, pivot locations 200, 202 will move toward each other and pivot location 204, 206 will also move toward each other.
When the motor is caused to be driven in the second direction, the threaded shaft 257 will rotate in the second direction. When the threaded shaft is driven in the second direction, the threaded engagement between the threaded shaft 257 and the first pivot bracket 241 causes the first pivot bracket to be moved away from the second pivot bracket 272. This moves the first upper scissor arm 252 away from the second upper scissor arm 256 and it also moves the first lower scissor arm 258 away from the second lower scissor arm 260. This movement causes the upper support bracket 254 to move toward the lower support bracket 262. As the upper support bracket 254 moves toward the lower support bracket 262 the scissor lift 163 is lowered.
When the lower frame 144 is supported on the ground or against the floor 104 of the exterior container 22, driving the motor in the second direction will cause the upper support bracket 254 to lower. Since the upper support bracket 254 is operably attached to the scissor mechanism 162, driving the motor in the second direction will cause the scissor mechanism to lower in the direction B of FIG. 9. The upper support bracket 254 will cause the plates 242, 244 to withdraw downward by the attachment of the plates 242, 244 to the first and second cross plate portions 232, 234 and the first and second cross plate portions attachment to scissor bars 184, 176. As the scissor lift lowers, it will rotate at the pivot bar 222 in the direction D shown in FIG. 9.
As the scissor mechanism lowers, bars 174, 182 will rotate and slide in the direction F within the respective slide tracks 203, 205. Likewise bars 180, 188 will rotate and slide in the direction F within the respective slide tracks 215, 217. Therefore the lower ends of bars 174, 182 will move away from the bottom ends of bars 176, 178 respectively. Likewise the upper ends of bars 180, 188 will move away from the upper ends of bars 178, 186. As the scissoring mechanism lowers, pivot locations 200, 202 will move away from each other and pivot location 204, 206 will also move away from each other.
The gap 236 between the first cross plate portion 232 and second cross plate portion 234 allows the scissor lift 163 including the threaded shaft 257 to move between the first and second cross plate portions 232, 234. This also allows the scissor lift 163 to be located between the first and second cross plate portions 232, 234 and between the first and second tower support plates 242, 244 when the scissor lift 163 and the scissor mechanism 162 are in or about the lowered position. FIG. 12 shows that the scissor lift 163 is partially located between the first and second cross plate portions 232, 234 where the scissor mechanism 162 is in a partially raised or partially lowered state.
A central notch 165 may be located along the crossbar 168 as shown in FIG. 9 to accommodate the position of the threaded rod 157 when the scissoring mechanism and the scissor lift are in a raised position.
FIG. 11 shows the lift mechanism in a collapsed or a lowered state. In the lowered state the bars 130, 132 cover or substantially cover the bars 148, 154. Therefore the bars 148, 154 are received within bars 130, 132. This allows the lift mechanism to take up less space when in the lowered state.
In some embodiments, a bottom edge 133 of bar 132 contacts a horizontal stop bar 149 of bar 148 to prevent further collapsing of the lift mechanism when in the lowered state. Similarly, a bottom edge 133a of bar 130 contacts a horizontal stop bar 151 of bar 154 to prevent further collapsing of the lift mechanism when in the lowered state.
FIG. 12 shows the scissor lift and the scissor mechanism in a partially lowered or a partially raised state. The state shown in FIG. 12 provides the upper frame 74 in a position between the position shown in FIG. 9 and the position shown in FIG. 11. The scissor mechanism can be stopped and therefore positioned anywhere between a fully raised position and a fully collapsed position. The configuration of the scissoring mechanism in FIG. 12 shows that the bottom end of bars 182 is located in the slide track of longitudinal base bars 166 further in the direction E as compared to the position shown in FIG. 9. Similarly, the top end of the bar 188 is positioned further in the direction E along the second upper slide track 217 of the upper platform 140 as compared to the position shown in FIG. 9.
Arms 256, 260 are located closer together in the position shown in FIG. 12 as compared to the position shown in FIG. 9. As the scissoring mechanism is in more of a collapsed position, more of the threaded rod is located between the second pivot bracket 272 and the first pivot bracket 241. The first pivot bracket 241 is therefore located further along the length of the threaded shaft 257 away from the second pivot bracket in the position shown in FIG. 12 as compared to the position shown in FIG. 9. Both the scissor lift 163 and the scissor mechanism 162 occupy a shorter and longitudinally wider area when moving from a fully raised position downward toward a lowered position.
The lift mechanism maintains the interior container in the same orientation in the raised position, in the lowered position, and when moving between the raised position and a lowered position. Therefore the interior container does not rotate clockwise or counter-clockwise from the position shown in FIG. 1, but instead is moved vertically relative to the exterior container 22 and the truck.
The lift mechanism is configured to maintain interior container in a horizontal orientation when the scissor lift mechanism is in the raised position and when the scissor lift mechanism is in the lowered position. The lift mechanism maintains the interior container in the horizontal orientation when moving between the raised position and a lowered position.
In some embodiments, the bottom of the interior container is parallel or substantially parallel to the floor 104 of the exterior container or the bed floor 9 of the truck. The lift mechanism maintains the interior container parallel or substantially parallel to the floor 104 of the exterior container or the bed floor 9 of the truck when moving between the raised position and a lowered position
In some embodiments, the lift mechanism is connected to the interior container only at the bottom of the interior container. The lift mechanism is located under the interior container to support the weight of the interior container and the contents loaded in the interior container.
FIG. 13 shows one embodiment where the arm 258 comprises teeth 278, 280 that mesh with teeth 286, 288 of arm 260 at lower support bracket 262. Arms 252 and 256 have identical teeth at the upper support bracket 254 but are not shown. The teeth 278, 280, 286, 288 form gears at the lower ends of arms 256, 260. Arm 258 has a first side wall 274 and a second sidewall 276. The teeth 278 extend from sidewall 274. The teeth 280 extend from sidewall 276. Arm 260 has a first sidewall 282 and a second sidewall 284. The teeth 286 extend from sidewall 282. Teeth 288 extend from sidewall 284. The teeth extend around the lower ends of each of the arms. The meshing of the teeth adds strength to the scissor lift. The pins 268 maintain the teeth of each adjacent arm at a predefined distance from the other so that the teeth of one arm properly mesh with the teeth of the other. The teeth of one arm engage the recesses between the teeth of the other arm. The teeth of one arm walk through the recesses between the teeth of the other arm as the scissor lift raises or lowers.
FIG. 14 shows a second embodiment lift mechanism comprising lift cylinders 290, 292. The rear side of the scissor mechanism 162 also comprises lift cylinders in a mirror image identical fashion about the longitudinal midplane of the scissoring mechanism arrangement located between bars 148, 158, so only the front side lift cylinders of FIG. 14 will be described.
Each lift cylinder comprises a cylinder 294, 296 and a shaft 298, 300. The shaft is movable in directions A and B of FIG. 14 relative to the cylinders 294, 296. The cylinders 294, 296 are not shown to scale. The bottom ends 302, 304 of each of the shafts 298, 300 are attached to the horizontal stop bar 149. The shafts 298, 300 are received in an opening on the bottom ends 306, 308 of the cylinders 294, 296. The opening on the bottom ends is sized to tightly seal the interface between the cylinders 294, 296 and the shafts 298, 300. The bottom ends 306, 308 are attached to the top of the bar 132. Shaft apertures (not shown) are provided in the upper surface of the bar 132 to allow the shafts 298, 300 to extend through toward the horizontal stop bar 149.
The cylinders 294, 296 comprise compressed air, gas, or liquid which causes the shafts to be biased to the extended position in the direction B. As the bottom ends 306, 308 are fixed to the top of the bar 132 and the shafts 298, 300 are attached to the horizontal stop bar 149, the compressed air, gas, or liquid will provide a lifting force which causes the cylinders and the bar 132 to rise in the direction A. This lifting force can assist the scissor lift 163 to handle greater loads, to speed lift rate, and/or to stead lifting.
When the scissoring mechanism and scissor lift is moved to the lowered position in the direction B, the shafts 298, 300 will be correspondingly received in the cylinders 294, 296 and the air, gas, or liquid in the cylinders will be compressed.
FIGS. 15 and 16 show a second embodiment scissoring mechanism 310. The scissoring mechanism 310 is identical to scissoring mechanism 216, except as described below and shown in FIGS. 15 and 16. The scissor lift 163 is replaced by a linear actuator 312. The linear actuator comprises a cylinder 314 and a rod 316. The rod is fixed to a sliding crossbar 318.
In some embodiments, the linear actuator 312 is a screw type linear actuators, where a screw (not shown) is driven by a motor, such as an electric motor 313. The screw pushes and pulls the rod 316 depending on the direction of rotation of the screw by the motor. In some embodiments, the linear actuator 312 is a hydraulic cylinder driven and withdrawn by hydraulic pressure created by a hydraulic pump (not shown) acting on hydraulic fluid.
The first rear scissor bar 320 is connected at a bottom to the sliding crossbar 318. The second front scissor bar 322 is connected at a bottom to the sliding crossbar 318. The first cross plate portion 232 and the second cross plate portion 234 are replaced with a continuous cross plate 324.
In operation, when the linear actuator causes the rod 316 to extend in the direction E, the scissoring mechanism rises. The bottom end of the second front scissor bar 322 is moved in the direction E toward the bottom 328 of a first front scissor bar 326. This causes connection points 340, 342 to pivot, move toward each other, and rise. This causes the top end of a fourth front scissor bar 344 to slide in the direction E toward a third front scissor bar 345. This causes the platform 140 to rise. The platform 140 is connected to bars 130, 132 as described regarding scissoring mechanism 216. Therefore as the platform rises, the upper frame 74 rises.
When the linear actuator causes the rod 316 to retract in the direction F, the scissoring mechanism lowers. The bottom end of the second front scissor bar 322 is moved in the direction F away from the bottom 328 of a first front scissor bar 326. This causes connection points 340, 342 to pivot, move away from each other, and lower. This causes the top end of a fourth front scissor bar 344 to slide in the direction F away from a third front scissor bar 345. This causes the platform 140 to lower. The upper frame 74 lowers and the platform lowers.
The linear actuator 312 is attached to a cross-member support bar 348. Cross-member support bar 348 is attached at opposite ends to bars 148, 154. Bar 348 provides stationary support for the linear actuator. The linear actuator 312 may be a screw type, wheel and axle type, a cam type, hydraulic, pneumatic, or other linear actuator.
FIG. 17 shows a third embodiment lift mechanism 350. The lift mechanism 350 comprises the upper frame 72 and the lower frame 144 of scissor mechanism 162. However, instead of providing the centrally located scissor mechanism 162, scissor lift 163, and drive mechanism 218, two scissor mechanisms 162, two scissor lifts 163, and two drive mechanisms 218 are provided, one at each longitudinal end of the upper frame 72 and the lower frame 144. The drive mechanisms are operated in sync from a central switch, such as switch 60, or controller so that the two scissor mechanisms 162 and the two scissor lifts 163 move up and down in sync.
In another embodiment, linear actuators, such as described regarding FIGS. 15 and 16, are provided at each of the two scissor mechanisms 162 of FIG. 17.
In a fourth embodiment, the interior container 41 may comprise multiple separate interior containers, such as a left side interior container 352 and a right side interior container 354 shown in FIG. 18. In some embodiments, each container 352, 354 may comprise left and right side drawers, such as those shown with interior container 41. In some embodiments, each container 352, 354 comprises front sliding drawers, such as those shown with interior container 51. In some embodiments, each container comprises a combination of front sliding and right and/or left side sliding drawers, such as shown with interior container 61. In some embodiments, the containers 352, 354 do not have drawers but instead have a top lid that opens to provide access to the internal space of the containers.
In some embodiments, the exterior container 22 is any conventional pickup truck bed toolbox.
In some embodiments, the lift mechanism 131 and interior container 41 are provided separate from the exterior container so that it may be installed in a conventional truck bed toolbox.
From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
