## Background
CROSS REFERENCE TO RELATED APPLICATION[S]
This application claims priority to U.S. Provisional Patent Application to Bates entitled “TRUCK BED DOOR WITH OPTIONAL EXTENSION AND ACCESSORIES,” Ser. No. 61/585,108, filed Jan. 10, 2012, the disclosure of which is hereby incorporated entirely herein by reference.


BACKGROUND
1. Technical Field
The following relates generally to a utility vehicle such as a pickup truck, and in particular to a pickup truck bed for use therein which has one or more access doors mounted in the side thereof.
2. State of the Art
A utility vehicle, such as a pickup truck, can have an open bed in the back thereof. The open bed is usually oriented horizontally, such that the pickup truck user can place items thereon. The bed is surrounded, or otherwise defined at its perimeter edges, by vertically oriented walls, such that the items placed on the bed are prevented from slipping off or falling out of the bed by the walls on the perimeter thereof.
A tailgate, or pivoting door, is often placed in the vertical wall, or is the vertical wall itself, at the rear of the utility vehicle to provide access to the bed. The tailgate can pivot between a vertical position and a horizontal position about a hinge between the tailgate and the truck bed. Lowering the tailgate from its vertical position to its horizontal position oftentimes provides better access to the bed and facilitates the loading and unloading of objects into and out of the bed.
The bed and surrounding walls function together to define and serve as a cargo storage area and a means of transporting various items and objects placed in the bed. Indeed, since the inception of the pickup truck, the bed of the pickup truck has been used to transport a myriad of items and objects from place to place, as desired by the user. It follows that the item, or items, the user transports can be of any shape, size, dimension, profile, and configuration that fits within the bed. But, depending on the unique configuration of the object to be placed in the bed, the user may wish to place the object at a particular spot within the bed.
Factors that contribute to the selection of the object's placement include, for example, accessibility, convenience and safety. Many times the user will place lighter items that could possibly blow out of the bed in the front of the bed. Other times, the user will place items in the front of the bed so as to prevent the item from sliding in the bed during the process of applying the brakes to stop the truck. Sometimes, it isn't the user that decides where items ultimately end up in the bed, but is instead the object itself that moves in the bed during transport.
To reach items in the bed, the user must either climb over the walls of the bed or operate the tailgate and climb onto the bed from the rear of the truck. This can be a cumbersome process, and at the very least, inconvenient. What's more, the user could be towing a fifth wheel trailer or a bumper hitch trailer that makes it impossible to lower the tailgate to gain entry into the truck bed. Further, the item the user wishes to reach may be buried, or otherwise surrounded, by other items in the truck bed, forcing the user to climb over all of the items in the bed just to reach the desired item. This is especially true when the buried, desired item is near the front of the truck bed, away from the tailgate.
Additionally, the truck user may wish to transport passengers in the truck bed. However, to safely transport such passengers, the truck bed must provide required safety conditions. Also, to gain entrance into the truck bed, the passenger must necessarily climb over the vertical walls of the truck bed. Alternatively, the passengers can access the bed via the tailgate, but must nevertheless climb into the bed, and perhaps climb over any objects in the truck bed to reach any provided seating accommodations.
In view of the foregoing, there is a great necessity for a truck bed that addresses the problems presented above and makes pickup trucks more adept for today's growing needs and versatility of the user's preferences. Truck bed accessories and attachments are a huge market for adding different varieties of uses of a truck bed. The present disclosure addresses the aforementioned issues.

The transparent material within the access door 30 may be as wide as the width of the access door 30, but may alternatively be any width not larger than the width of the access door 30. The transparent material may function as a window when in the deployed position.
As depicted in FIG. 4, embodiments of the truck 10 may further comprise the truck bed 20 being configured to receive a roll bar 80, removable seating 84, or both. The roll bar 80 may be configured to be repeatedly and releasably coupled to the truck bed 20, such as on the sidewalls 21 or the bed surface 12, by fasteners, such as bolts, pins, releasable clips, latches, clasps, or other user-operated fastening means that rigidly secure the roll bar 80 to the truck bed 20 during use and also permit the user to remove the roll bar 80 from the truck bed 20, as needed, when not in use. The removable seating 84 may be configured to be repeatedly and releasably coupled to the truck bed 20, such as on the sidewalls 21 or the bed surface 12, such that the removable seating 84 is positioned within the truck bed 20 so as to permit a user to sit on the removable seating 84 and have ample leg room between the removable seating 84 and the front end 22 of the truck bed 20. With the removable seating 84 coupled to the truck bed 20, a user may enter the truck bed 20 via the access door 30. Specifically, the user may operate the handle 36 to open the access door 30 to expose the opening 30a through which the user may gain easy access to the interior of the truck bed 20 to sit on the removable seating 84. Embodiments of the truck 10 may further comprise the roll bar 80 being coupled to the truck bed 20 and being configured so as to functionally protect the removable seating 84 and any user that may be seated therein. In other words, the roll bar 80 may be structured to protect the occupants of the removable seating 84 in the event the truck 10 rolls or tips over. With the roll bar 80 and the removable seating 84 in place within the truck bed 20, the user may operate the handle 36 to open the access door 30 to expose the opening 30a through which the user may gain easy access to the interior of the truck bed 20 to sit on the removable seating 84 under the protection of the roll bar 80. Embodiments of the truck 10 may further comprise the access door 30 being positioned in the truck bed 20 in one or more sidewalls 21.
As further depicted in FIG. 4, the truck bed 20 may further comprise one or more vents 19 that place the interior space of the truck bed 20 in fluidic communication with the air conditioning system 17 and the heating system 18 of the truck 10. The vents 19 may be further configured to direct the treated air from the air conditioning or heating systems, 17 and 18, of the truck 10 into the interior space of the truck bed 20 to control the temperature of the interior space of the truck bed 20. The vent 19 may be configured in the front end 22 of the truck bed 20, the sidewalls 21 of the truck bed, the access door 30, or in any combination of these.
Referring now to FIGS. 5 and 6, embodiments of the truck 10 may further comprise a truck bed cover 70. The cover 70 may be a full-size tonneau cover that covers the entire truck bed 20 from sidewall 21 to sidewall 21, as well as from front end 22 to back end 23. Embodiments of the truck 10 may further comprise the cover 70 being configured to correspond to the features of the access door 30. For example, the cover 70 may further comprise front lids 76 that are positioned in the cover 70 to correspond to the access door 30, as depicted in FIG. 6. The front lids 76 may be configured to lift or rise up from the cover 70, in a pivoting manner, as depicted in FIG. 6, or in a completely releasable manner, or a combination of both, to expose the interior truck bed 20, even with the cover 70 coupled to the top of the truck bed 20 and the access door 30 being in the closed position. In this way, the user may lift the front lid 76, as needed, to reach down into the truck bed 20 to retrieve items and objects therein. Also, the access door 30 may be operated to open independently of the front lid 76, such that a user may access the interior space of the truck bed 20 without having to operate the front lid 76. Alternatively, as depicted in FIG. 6, the user may open the front lid 76 as well as open the access door 30 to gain easier and more convenient access into the interior of the truck bed 20. Each of the front lids 76 may be configured to be locked in the closed position, as depicted in FIG. 5, to prevent access into the interior space of the truck bed 20.
Referring still to FIGS. 5 and 6, embodiments of the truck 10 may further comprise a back lid 78 that may function in a similar manner to the front lid 76, except the back lid 78 may communicate with the rear end 23 of the truck bed 20, such as the tailgate 27. The back lid 78 may be configured to lift or rise up from the cover 70, in a pivoting manner, as depicted in FIG. 6, or in a completely releasable manner, or a combination of both, to expose the interior of the truck bed 20, even with the cover 70 coupled to the top of the truck bed 20 and the rear end 23 (e.g., the tailgate 27) in the closed position. In this way, the user may lift the back lid 78, as needed, to reach down into the truck bed 20 to retrieve items and objects therein. Also, the tailgate 27 may be operated to open independently of the back lid 78, such that a user may access the interior space of the truck bed 20 without having to operate the back lid 78. Alternatively, as depicted in FIG. 6, the user may open the back lid 78 as well as open the rear end 23, including the tailgate 27, to gain easier and more convenient access into the interior of the truck bed 20. The back lid 78 may be configured to be locked when in the closed position, as depicted in FIG. 5, to prevent access into the interior space of the truck bed 20.
With the cover 70 in the closed position, the user of the truck 10 may control the temperature of the interior space of the truck bed 20 via the vents 19 and the air conditioning and heating systems, 17 and 18, in communication therewith, as schematically depicted in FIG. 16.
Referring to FIGS. 7-9, embodiments of the truck 10 may further comprise an extension body 50 and a cap member 60. Embodiments of the extension body 50 may comprise the extension body 50 having a front end 52, a rear end 53, a top end 54, and a bottom end 55, as shown in FIG. 7. Embodiments of the extension body 50 may include the extension body 50 being a solid piece. Embodiments of the extension body 50 may include the extension body 50 being comprised of metals, plastics, fiberglass, or other like materials, the metals, plastics, fiberglass and materials being configured with the properties and characteristics to satisfy the safety and operational requirements of passenger vehicles.
Embodiments of the truck 10 include the extension body 50 having a central aperture 56 defined by and within the external border of the extension body 50, the external border being comprised of the front end 52, the rear end 53, the top end 54, and the bottom end 55. Embodiments of the truck 10 include the central aperture 56 being hollow, or otherwise open, such that line of sight is not obstructed through the central aperture 56 and objects may be passed through the central aperture 56, if needed.
However, alternative embodiments of the truck 10 may include, as shown, the central aperture 56 having inserted therein a transparent material, such as glass, plexiglass, or other like material, the transparent material functioning as a window. Embodiments of the truck 10 may include the transparent material being rigidly fixed within the central aperture 56. Embodiments of the truck 10 may include the transparent material being configured to open within the central aperture 56. For example, but not in a limiting way, the transparent material may be configured to pivot within the central aperture 56 to open the window. Embodiments of the truck 10 include the transparent material being configured to be detached and removed completely out of the central aperture 56. Embodiments of the truck 10 include the transparent material pivoting only a predetermined distance with respect to the central aperture 56, such that the transparent material can only create a predetermined-sized opening in the central aperture 56. Further in example, but not in a limiting sense, the transparent material within the central aperture 56 can retract out of the central aperture 56 so that the transparent material is completely removed from the central aperture 56. This can be accomplished, for example, by decoupling the transparent material from the extension body 50, so that the central aperture 56 is hollow, or otherwise open.
Embodiments of the truck 10 may include the extension body 50 being configured to releasably and repeatedly couple to the access door 30. For example, the bottom end 55 of the extension body 50 and the top edge 34 of the access door 30 can be configured with corresponding mating mechanisms that permit the bottom end 55 of the extension body 50 to releasably and repeatedly couple to the top edge 34 of the access door 30 to secure the extension body 50 to the access door 30, such that the extension body 50 moves with the pivoting movement of the access door 30. Accordingly, once properly coupled, the access door 30 and the extension body 50 function as a unitary body, with the extension body 50 pivoting with the access door 30 between its open and closed positions.
As desired by the user, the extension body 50 may be configured to move from its upright state above the access door 30. For example, and not in any way limiting, embodiments of the truck 10 may include the extension body 50 being decoupled and completely removed from the access door 30. Embodiments of the truck 10 may include the extension body 50 being configured to pivot about the corresponding mating mechanisms, which hold the extension body 50 to the access door 30. Such pivoting allows the extension body 50 to be structurally configured to pivot down into the truck bed 20 and out of view. In this way, the extension body 50 remains coupled to the access door 30, but yet, at the same time, is stored away in the bed 20 of the truck 10 and thus concealed from view. In this pivoting configuration, the extension body 50 further comprises a locking mechanism that locks the extension body 50 in the stored position and in the upright position.
In embodiments of the truck 10 where the access door 30 contains the transparent material therein and the extension body 50 is coupled to the access door 30, as described in detail above, the extension body 50 has no need of its own separate transparent material in the central aperture 56. Indeed, when the access door 30 is configured to permit its transparent material to rise up out of the interior space of the access door 30 through the slot in the top edge 34, the transparent material may also rise up through a slot in the bottom end 55 of the extension body 50 and enter the central aperture 56. The slot in the top edge 34 and the slot in the bottom edge 55 are structured to correspond with one another and functionally communicate with one another to permit the transparent material to transition therethrough without undue resistance or hindrance. As the transparent material moves up through the slots and enters the central opening 56, the transparent material engages and slides within grooves on the interior surfaces of the front and rear ends 52 and 53, respectively, until the transparent material rises up to and abuts a groove on the interior surface of the top end 54 of the extension body 50. Once the transparent material engages the groove on the interior surface of the top end 54, the transparent material comes to a rest and is secured within the central opening 56 so as not to move. In this way, the transparent material in the access door 30 can rise up into the central aperture 56 of the extension body 50 and close the central aperture 56. The transparent material thus effectively seals the central aperture 56 from the ingress of air, wind, rain, and other elements. Thereafter, as desired by the user, the transparent material can be retracted out of the central aperture 56, in much the same way it was inserted, and can be stored within the interior space of the access door 30, until it is needed again. A mechanically- or electrically-driven rising mechanism, operated by the user, can control the lifting and lowering of the transparent material from within the access door 30.
With continued reference to FIGS. 7-9, embodiments of the truck 10 may further comprise a cap member 60. The cap member 60 may comprise a front end 62, a rear end 63, a top end 64, and a bottom end 65. The cap member 60 may have a sidewall aperture 68 defined in the sidewall of the cap member and within the external border of the cap member 60, the external border being comprised of the front end 62, the rear end 63, the top end 64, and the bottom end 65. The cap member 60 may have a back wall aperture 69 defined in the back wall of the cap member 60 and within the external border of the cap member 60. Embodiments of the truck 10 may include the central aperture 68 and/or the back wall aperture 69 being hollow, or otherwise open, such that line of sight is not obstructed through the central or back wall apertures 68 and 69 and objects may be passed through the apertures 68 and 69, if needed. The cap member 60 may be further comprised of metals, plastics, fiberglass, or other like materials, the metals, plastics, fiberglass and materials being configured with the properties and characteristics to satisfy the safety and operational requirements of passenger vehicles and truck caps. The cap member 60 may also have defined within the central aperture 68 a transparent material, such as glass, that functions as a window. The window may prop open or may be completely removed from the cap member 60, in much the same way the transparent material of the extension body 50 is secured within the central aperture 56 and operates with respect to the extension body 50. Alternatively, the transparent material in the cap member 60 may be fixed within the cap member 60.
Embodiments of the truck 10 may further comprise the cap member 60 being configured to be placed over the truck bed 20 and to secure to the truck bed 20, such as to secure to the top edges 24 of the truck bed 20, such that the cap member 60 may define a first space 91 under the cap member 60 and between bed surface 12 of the truck bed 20 under the cap member 60. The rear end 63 of the cap member 60 may be configured to correspond to and contact the rear end 23 of the truck bed 20. Likewise, the front end 62 of the cap member 60 may be configured to correspond to and contact the front end 22 of the truck bed 20. The front end 62 may also be configured to releasably and repeatedly couple to the front end 22, as desired by the user, whereas the rear end 63 may not necessarily couple to the rear end 23 to provide for the opening and closing of the tailgate 27 independently of the cap member 60. The vertical side walls of the cap member 60 may be configured to correspond to and contact the vertical side walls 21 of the truck bed 20. Moreover, the vertical side walls of the cap member 60 may be configured to releasably and repeatedly couple to the vertical side walls 21 of the truck bed 20, as desired by the user. In this way, the cap member 60 can be secured to the truck bed 20 so that the first space 91 is defined therebetween.
Embodiments of the truck 10 may further comprise the cap member 60 further comprising a cavity 66, the cavity 66 being defined in a vertical side wall of the cap member 60 above the access door 30. Embodiments of the truck 10 include the cavity 66 being configured of a size and shape to correspond to the size and shape of the extension body 50 and to functionally engage the extension body 50. In this configuration, the cavity 66 and the extension body 50 can releasably and repeatedly functionally couple together, as desired by the user. Indeed, the cavity 66 and the extension body 50 may be configured to structurally correspond to one another to effectively seal the cavity 66 from the ingress of air, wind, water, rain, and other like elements into the cavity 66 under the condition that the extension body 50 and the access door 30 are in the closed position. Also in this configuration, under the condition that the cap member 60 is secured to the truck bed 20, the user may operate the handle 36 of the access door 30 to pivot the access door 30 from its closed position to its open position. In so doing, the extension body 50, which is coupled to the access door 30, as described herein, also pivots with the access door 30 from the closed position to the open position. Accordingly, in the open position, the access door 30 and the extension body 50 reveal an entrance, comprised of the opening 30a and the cavity 66, to the interior of the first space 91 defined by the cap member 60 and the truck bed 20 and through which the user may enter, or otherwise access, the first space 91.
Embodiments of the truck 10 may further comprise the cavity 66 being configured of a size and shape to correspond to the size and shape of the transparent material housed within the interior of the access door 30. In this configuration, the cavity 66 and the transparent member (i.e., window) stored in the interior of the access door 30 may be configured to structurally correspond to one another and to functionally engage one another. That is, the transparent member may be configured to deploy out of the access door 30 through the slot in the top edge 34 and engage the cavity 66 to effectively seal the cavity 66 from the ingress of air, wind, water, rain, and other like elements into the cavity when the transparent member is in the deployed position. The cavity 66 is likewise structurally configured with grooves on its inner surfaces to receive and engage the transparent material when the transparent material is deployed in the cavity 66. Additionally, a flexible material, like rubber, may be placed in, around, or near the grooves to engage the transparent material and function as a gasket to effectively seal the cavity 66. It follows that in this configuration, the extension body 50 may be the transparent material that is configured in the access door 30, because the transparent material in the access door 30 functionally engages and covers the cavity 66. Thus, similarly to that described above, when the cap member 60 is secured to the truck bed 20, the user may operate the handle 36 of the access door 30 to pivot the access door 30 from its closed position to its open position. In so doing, the transparent material that is deployed in the cavity 66 also pivots with the access door 30 from the closed position to the open position. Accordingly, in the open position, the access door 30 and the deployed transparent material reveal an entrance in the side wall 21 of the truck bed 20 and the cap member 60, respectively, that exposes a portion of the interior of the first space 91 defined by the cap member 60 and the truck bed 20 and through which the user may access the first space 91.
Embodiments of the truck 10 further comprise the removable seating 84 being configured on the truck bed 20 within the interior of the first space 91 defined between the cap member 60 and the bed surface 12. The removable seating 84 may be coupled to the truck bed 20 under the cap member 60, such that the cap member 60 encloses the removable seating 84 within the interior first space 91. In this way, with the cap member 60 covering the removable seating 84, the access door 30 and the extension member 50 may provide convenient entrance for any passengers into the first space 91 for the passengers to utilize the removable seating 84. Accordingly, the removable seating 84 may be coupled to the truck bed 20 to provide extra seating for passengers, as needed. The removable seating 84 may also be configured with safety restraints and other necessary safety features that satisfy the rules and regulations that govern the safety of passengers within vehicles. In addition to the foregoing, embodiments of the truck 10 may further comprise the cap member 60 being configured with the roll bar 80 that is integral to the cap member 60, such that under the condition the cap member 60 is functionally coupled to the truck bed 20, the roll bar 80 is also naturally positioned over the removable seating 84 to protect the passengers sitting in the removable seating 84 positioned within the first space 91. Alternatively, the removable seating 84 may be configured with the roll bar 80 integral to the removable seating 84, the roll bar 80 functioning to protect the passengers sitting in the removable seating 84 positioned within the first space 91. As further depicted in FIGS. 8 and 9, the rear end 63 of the cap member may have configured therein a lift gate 67 that may pivot between closed and open positions, the closed position being depicted in FIG. 8 and the open position being depicted in FIG. 9.
With the extension member 50 and the cap member 60 in functional communication with the access door 30 and the truck bed 20, respectively, the user of the truck 10 may control the temperature of the interior space of the truck bed 20 under the cap member 60 via the vents 19 and the air conditioning and heating systems, 17 and 18, in communication therewith, as schematically depicted in FIG. 16. In addition, under the condition that the cap member 60 is coupled to the truck bed 20 to create the first space 91 in which passengers may be seated on the removable seating 84, the rear window of the truck 10 may be configured to slide open or be removed from its normal position, to allow passengers within the first space 91 to communicate with passengers within the cab of the truck 10.
As depicted in FIGS. 10-12, embodiments of the truck 10 further comprise the cap member 60 having a shorter length than the length of the truck bed 20, such that the rear end 63 of the cap member 60 terminates prior to reaching the rear end 23 of the truck bed 20. In this configuration, the rear end 63 of the cap member 60 may be configured to extend down into the truck bed 20 and contact the bed surface 12. Moreover, the rear end 63 of the cap member 60 may be further configured to functionally engage the bed surface 12 and the interior surfaces of the side walls 21. The bed surface 12 and the interior surfaces of the side walls 21 may be configured with engagement sections that are structured to functionally engage the rear end 63 of the cap member 60 that extends down into the truck bed 20 so that the rear end 63 and the corresponding engagement sections effectively seal the first space 91 from the ingress of air, wind, water, rain, and other like elements into the first space 91. Such a benefit is desirable, especially when the first space 91 is being utilized with the removable seating 84 to transport additional passengers, as desired.
In addition, embodiments of the truck 10 may further comprise a panel 86 that may be releasably and repeatedly coupled to the rear end 63 of the cap member 60 and the truck bed 20. In this way, the rear end 63 of the cap member 60 does not need to be configured to extend down into the interior space of the truck bed 20 to seal the first space 91. Instead, the panel 86 may be configured to functionally engage the rear end 63 of the cap member 60, the bed surface 12, and the interior surfaces of the side walls 21. As disclosed above, the bed surface 12 and the interior surfaces of the side walls 21 may be configured with engagement sections. The panel 86 may be configured to functionally engage these engagement sections so that the panel 86 and the corresponding engagement sections of the truck bed 20 effectively seal the first space 91 under the cap member 60 from the ingress of air, wind, water, rain, and other like elements into the first space 91. Such a benefit is desirable, especially when the first space 91 is being utilized with the removable seating 84 to transport additional passengers, as desired. A second space 92 is created behind the cap member 60 when used in this configuration. The second space 92 may be utilized as a storage space to haul, store, and place items. The second space 92 will be described in greater detail below.
Embodiments of the truck 10 further comprise the cover 70 that is configured to engage the cap member 60 that is shorter than the length of the truck bed 20. As depicted in FIGS. 10-12, the cover 70 may comprise a front end 72, a rear end 73, a top end 74, and a bottom end 75. The cover 70 may be configured to completely cover the remaining portions of the truck bed 20 to enclose the second space 92 behind the first space 91 created by the cap member 60 and the truck bed 20. The front end 72 of the cover 70 may abut or contact the exterior face of the rear end 63 of the cap member 60. Alternatively, the front end 72 of the cover 70 may approach, but not contact the cap member 60. The rear end 73 of the cover 70 may contact, or otherwise abut, the rear end 23 of the truck bed 20, but not necessarily functionally engage the rear end 23 so as to prevent the rear end 23, or the tailgate 27 positioned in the rear end 23, from releasing from the truck bed 20 and pivoting between a closed position and an open position. The side portions of the cover 70 may releasably and repeatedly couple to the top edges 24 of the truck bed 20 to secure the cover 70 to the truck bed 20. The cover 70 can be configured with a lifting mechanism to allow the cover 70 to lift off or pivot off of the truck bed 20 to provide easy and convenient access to the second space 92. Also, the cover 70 can be locked with a key, by the user, so as to prevent the cover 70 from opening and exposing the second space 92 without the user operating the key, or at least unlocking the cover 70 with the key. The second space 92 can provide a secure area wherein the user may transport objects and other items, as desired by the user.
With the extension member 50 and the cap member 60 in functional communication with the access door 30 and the truck bed 20, respectively, and the panel 86 and the cover 70 in functional communication with the truck bed 20 and the cap member 60, as depicted in FIG. 11, the user of the truck 10 may control the temperature of the first space 91 via the vents 19 and the air conditioning and heating systems, 17 and 18, in communication therewith, as schematically depicted in FIG. 16. In addition, under the condition that the cap member 60 is coupled to the truck bed 20 to create the first space 91 in which passengers may be seated on the removable seating 84, the rear window of the truck 10 may be configured to slide open or be removed from its normal position, to allow passengers within the first space 91 to communicate with passengers within the cab of the truck 10.
