DETAILED DESCRIPTION OF INVENTION
The present invention, together with a standard domestic pickup truck into which the present invention is installed, form a fully functional recreational vehicle. When the present invention is placed in the compacted (that is, closed) position, the height does not extend more than six inches above the roof of the truck cab, the width does not extend beyond the sidewalls of the truck, the rear portion does not extend beyond the rear bumper of the truck, and the front portion does not extend over the cab of the truck. This very compact configuration minimizes wind drag and wind noise when traveling and provides excellent aesthetics. When the present invention is in the expanded (that is, open) position, a tented shelter extends in the forward direction over the truck bed, and the rearward portion extends over and beyond the truck tailgate. The sides of the tented shelter extend laterally to the width of the truck bed sidewalls. The present invention is comprised of an upper unit, which includes the components installed above the truck bed, and a lower unit, which includes the components installed within the truck bed. The upper and lower units are modular and separable.
FIG. 1 is an elevation view of the right side of the present invention, shown in the compacted position, and mounted onto a standard-size pickup truck 1 having a bed length of 6-½ feet. The present invention comprises a rigid aluminum lid 2, which, with the present invention in the compacted position, is attached to the right side panel 3 of the upper unit 4 by two cam latches 5 and is also attached to the left side panel by to two additional cam latches, as shown in FIG. 3. The lid 2 is rotatably attached to the rear side panel 6 of the upper unit 4 by a lid hinge 7 that is attached to the top edge of the rear side panel 6 and by an additional lid hinge that is attached to the left side panel of the upper unit, as shown in FIG. 3. A pneumatic gas spring 8 has one end rotatably mounted to the lower rear corner of the right side panel 3 and the other end rotatably mounted to the right edge of the lid 2. A sink drain outlet 9, a furnace exhaust vent 10, a 115 volt alternating current (VAC) inlet plug 11, a first freshwater tank inlet connector 12, a second freshwater tank inlet connector 13, and a blackwater tank vent 14 are mounted on the right side panel 3 at the locations shown. A jack attachment fitting 15 is positioned near the lower rear edge of the right side panel 3. An upward-facing solar panel 16 is rotatably mounted to the upper surface of the lid 2 with solar panel hinges 17 (see also FIG. 3). A right strut upper receiver 18 is mounted to the right edge of the lid 2.
FIG. 2 is an elevation view of the right side of the present invention, shown in the expanded position, and mounted onto a standard-size pickup truck 1. As shown, the lid 2 has been rotated approximately 180 degrees about the lid hinges 7, and is supported by the pneumatic gas spring 8 in combination with a right strut 19, whose ball-shaped upper end is removably and rotatably attached to the right strut upper receiver 18 and whose lower end is attached to a right strut lower receiver (shown on FIG. 11) on the rear side panel 6. A foldable tent 20 is positioned over the right side panel 3. the left side panel shown in FIG. 3, and the opened lid 2. The right side of the tent 20 comprises two screened windows 21 with zippered storm flaps, which are positioned as shown. The tent 20 is supported by an internal frame system that is described in reference to FIG. 7. As shown in FIG. 2, the solar panel 16 has been repositioned by rotating it about the solar panel hinges 17 so that it faces upward when the lid is open. An extendable solar panel support member 22 is removably pinned to each side of the solar panel 16 to provide structural support to the solar panel 16.
FIG. 3 is an elevation view of the left side of the present invention, shown in the expanded position, and mounted onto a standard-size pickup truck 1. The left side of the tent 20 comprises a zippered door flap 23, a covered access port 24, and a screened window 21 with zippered storm flap. The left side panel 25 comprises a hinged human access door 26 for ingress and egress to and from the interior of the present invention when it is in the expanded position. The human access door 26 is attached to the left side panel 25 with two human access door hinges 27 positioned along the lower edge of the human access door 26. The two human access door hinges 27 are constructed so that they are able to come apart when the human access door 26 is open, thereby enabling the human access door 26 to be optionally removed from the left side panel 25. The human access door 26 comprises two key locks 28 that enable it to be locked when closed. A handhold 29 is mounted on the left side panel 25 on each side of the human access door 26. The left side panel 25 further comprises a hinged propane tank access door 30, which covers a propane tank storage compartment. The two cam latches 5 located along the upper edge of the left side panel 25 are used to secure the lid to the left side panel 25 when the present invention is in the compacted position. There are two jack attachment fittings 15 located near the bottom edge of the left side panel 25. The opened lid 2 is supported by a pneumatic gas spring 8 in combination with a left strut 31, as well as a lid hinge 7. The pneumatic gas spring 8 has one end rotatably mounted to the lower rear corner of the left side panel 25 and the other end rotatably mounted to the left edge of the lid 2. The left strut 31 is a part of a combination device that is used as a tent erector tool as well as a support strut, as described in reference to FIGS. 4 through 6.
FIG. 4 is a right side elevation view of the present invention mounted onto a pickup truck 1 showing a person 32 in the process of raising the tent 20 from the compacted to the expanded position, with the tent 20 shown partially expanded. The tent 20 is expanded by pushing on the tent erector tool 33, which causes the lid 2 to rotate about the lid hinges 7. The upper end of the tent erector tool 33 is removably and rotatably inserted into a left strut upper receiver 34 mounted on the left side of the lid 2. The weight of the lid 2 is partially offset by the lifting force produced by the pneumatic gas spring 8, thereby reducing the pushing force required on the tent erector tool 33.
FIG. 5 is a side view of the tent erector tool 33 shown in a partially extended position, with an upper section rotatably connected to a lower section via a hinge 35. The upper section of the tent erector tool 33 is the left strut 31 shown in FIG. 3, and the lower section is an extension handle 36.
FIG. 6 is a perspective view of the upper end of the left strut 31 being inserted into the left strut upper receiver 34. As shown, the upper end of the left strut 31 terminates in a disc-shaped appendage, which can be rotatably and removably inserted into a mating cavity in the left strut upper receiver 34. When the hinge 35 of the tent erector tool 33 is rotated so that the left strut 31 and the extension handle 36 form a linear pole, the tent erector tool 33 can be used as an extension lifting tool to raise the tent 20 from the compacted to the expanded position, as shown in FIG. 4. When the hinge 35 of the tent erector tool 33 is adjusted so that the left strut 31 and the extension handle 36 are positioned side-by-side, the left strut 31 can be installed as a support between the left side panel 25 and the lid 2, as shown in FIG. 3.
FIG. 7 is a first perspective view of the present invention shown in the expanded position, showing portions of the upper unit 4 and the lower unit 37, with the tent and solar panel removed for clarity. The tent is supported by a collapsible frame, which is comprised of three U-shaped sections, including a front frame section 38, a center frame section 39 and a rear frame section 40. The two bottom ends of the center frame section 39 are connected to the left and right rear corners of the floorspace with rotatable bottom connectors. One of these rotatable bottom connectors is shown in FIG. 7. Two frame side connectors 41 connect the ends of the front frame section 38 and the rear frame section 40 to the two sides of the center frame section 39 as shown. The frame side connectors 41 allow the front and rear frame sections 38, 40 to independently rotate about the center frame section 39, and they also allow the front and rear frame sections 38, 40 to slide up and down along the center frame section 39. The frame side connectors 41 each incorporates a slide stop 42 to enable the front and rear frame sections 38, 40 to be locked into position on the center frame section 39 when they are raised into their fully upright positions, thereby forming a rigid frame support for the tent fabric. A rear cable-and-pully assembly 43 has one end attached to the top middle of the center frame section 39 and the other end attached to the rear end of the lid 2. When the lid 2 is being opened, the rear cable-and-pully assembly 43 pulls the three frame pieces 38, 39 and 40 into their upright positions. A pair of forward cable-and-pully assemblies 44 each has one end attached to a side frame connector 41 and the other end attached to a front inside corner of the interior floorspace. These forward cable-and-pully assemblies 44 prevent the frame sections 38, 39 and 40 from over-rotating when they are pulled into their fully upright positions.
When the present invention is in the compacted position, as shown in FIG. 1, the three frame sections 38, 39 and 40 fold together so as to fit within the interior of the upper unit 4 with no disassembly of the frame sections 38, 39 and 40 required. The floor 45 is positioned at a height just above the height of the side rails of the pickup truck. A commercially available kitchen unit 46 comprising a sink, faucet and two stovetop burners is positioned in the front left corner of the floorspace on top of a cabinet (not shown). Hoses (not shown) that are connected to the bottom side of the kitchen unit 46 supply propane, cold water, and hot water into the kitchen unit 46, and a sink drain hose (not shown) provides an outlet for sink water to flow to the sink drain outlet 9 on the right side panel shown in FIG. 1. Each of these hoses is fitted with a quick-disconnect fitting to allow the kitchen unit 46 to be easily removed from the cabinet top for stowage. An example of a typical quick-disconnect fitting is shown in FIG. 15. The quick-disconnect fittings are located in the cabinet beneath the kitchen unit 46. A portable refrigerator 47 is positioned in the front right corner of the interior floorspace, also on top of a cabinet (not shown). The kitchen unit 46 and the refrigerator 47 are removably mounted on cabinet tops when they are in use and are repositioned on the floor of the interior space when they are being stowed, as when present invention is in the compacted position.
A commercially available, propane-powered combination furnace/hot water heater (not shown) occupies the space in the front right corner cabinet below the refrigerator 47. An equipment cabinet 48 on the right side of the floorspace holds a lithium battery and an inverter and has a padded seat top. An electrical control panel 49 is mounted on the front of the equipment cabinet 48 and is shown in detail in FIG. 13. A first storage cabinet 50 with a hinged seat top is located in the right rear corner of the floorspace adjacent to the equipment cabinet 48. A rotatable and removable table 51 is mounted in front of the corner between the equipment cabinet 48 and the first storage cabinet 50. A second storage cabinet 52 with a hinged seat top is positioned in the rear center of the floorspace, and a toilet cabinet 53 with a hinged seat top is positioned in the left rear corner. The toilet within the toilet cabinet 53 is a commercially available, marine-type flush toilet. When the toilet is flushed, the contents of the toilet bowl are transferred to a blackwater tank in the lower unit 37, which is described in reference to FIG. 10. The lid 2 forms a bed platform when open. The bed is supported on the left side by a lid hinge 7, a pneumatic gas spring 8 and the left strut 31. The bed is supported on the right side by a lid hinge 7, a pneumatic gas spring 8, and the right strut 19, as shown in FIG. 2. The lid 2 is fitted with a custom mattress pad 54. The lid 2 comprises a rainwater catchment trough 55 that extends around the perimeter of the lid 2. The rainwater catchment trough 55 captures rainwater that falls down around the outside of the tent and enables the rainwater to be stored in a freshwater holding tank. This novel rainwater catchment feature is not disclosed in any examples of the prior art. Details of the rain catchment system are described in reference to FIGS. 8 and 9.
FIG. 8 is a second perspective view of the present invention shown in the expanded position, showing the right side panel 3, the front panel 56 and a portion of the interior, with the tent, the cable-and-pully assemblies, solar panel and the mattress pad removed for clarity. A rainwater drain connector 57 in the front right corner of the rain catchment trough 55 is shown. A removable hose (not shown) may be used to transport rainwater from the rainwater drain connector 57 to one of the two tank water inlet connectors 12, 13 located of the right side panel 3. The rotatable bottom connector 58 connected to the left bottom end of the center frame section 39 is shown attached to the inside of the left rear corner of the left interior wall 59.
FIG. 9 is a detail view of a portion of the water-catchment system. A fabric tab 60 comprising a loop at one end is sewn to the tent fabric parallel to the bottom of the tent around the inside perimeter of the tent 20. The loop of the tab 60 is inserted within a circular channel 61 in which a segment of the circle has been cut out. A rigid rod 62 is passed through the loop, thereby preventing the loop from pulling out of the circular channel 61. The bottom edge of the tent 20 extends into the rain catchment trough 55. Rainwater that strikes the outer surface of the tent fabric travels down the fabric until it falls into the rainwater catchment trough 55. The bottom edge of the tent 20 is constrained within the rainwater catchment trough 55, thereby preventing the tent bottom from blowing into the bed area, even in a strong wind.
FIG. 10 is a perspective view of the lower unit 37 showing the underside, with the bottom plate and hoses removed for clarity. Three water tanks mounted within the lower unit 37 include a first freshwater tank 63, a second freshwater tank 64, and a blackwater tank 65. In a preferred setup configuration, the first freshwater tank 63 is used to store rainwater, the second freshwater tank 64 is used to store potable water, and the blackwater tank 65 is used to store toilet refuse. The three tanks 63, 54 and 65 are supported on their bottom edges with aluminum angles 66 and covered on their lower sides with a bottom plate (shown in FIG. 11), which extends across the entire bottom area. The blackwater tank outlet is equipped with a macerator pump 67, which facilitates dumping of the blackwater tank. The lower unit 37 comprises a rear door 68 that provides access to drain hoses for the three tanks 63, 64 and 65. The lower unit 37 is designed as a self-contained modular system that may be removably attached to the underside of the upper unit 3. Hoses and wires that connect the upper unit 3 and the lower unit 37 are fitted with quick-disconnect fittings so that the two units may be quickly and easily detached.
FIG. 11 is a rear view of the present invention mounted onto a pickup truck 1, shown with the truck tailgate 69 in the open position. As shown, the bottom plate 70 of the lower unit 37 terminates approximately one foot above the bottom of the truck bed 71, thereby providing significant storage space in the bed below the lower unit 37 for cargo such as a commercial gun safe 72. The solar panel 16 is attached to the inverted top of the lid 2 and supported by two solar panel support members 22. A shower port 74 provides access to a hot and cold water shower spigot (not shown). A person 32 is shown on a stowable ladder 75 in the process of entering the interior of the upper unit 4. The lower end of the right strut 19 is attached to a right strut lower receiver 76 that is mounted on the lower right edge of the rear face 6. The left strut 31 is attached to the left strut lower receiver 77, which is mounted on the lower left edge of the left panel 25 and shown in detail in FIG. 12.
FIG. 12 is a detail perspective view of a portion of the left strut 31, the extension handle 36, and left strut lower receiver 77, which is mounted on the bottom rear corner of the left side panel 25, as shown in FIG. 11. As shown in FIG. 12, the lower end of the left strut 31 is fitted with a left strut lower connector 78 that comprises two holes, which accept a pin 79 that passes through the left strut lower connector 78 and through a hole in the left strut lower receiver 77, thereby rotatably and removably attaching the left strut 31 to the left side panel 25. The left strut lower connector 78 attaches around the shaft of the left strut 31 with a friction fitting, which may be loosened or tightened, thereby providing a length adjustment to the left strut 31.
FIG. 13 is a cross-section detail view of the components that attach the present invention to a pickup truck. Components for the left side attachment are shown, and there are similar components for the right side attachment. The vertical leg of an aluminum angle 80 is attached to the left side of the lower unit 37 with a plurality of riveted nut and bolt assemblies 81 (one shown). The horizontal leg of the aluminum channel 80 is attached to the bottom of the left side panel 25 with a plurality of stake pocket bolts 82 (one shown) that pass through holes in the left side panel 25 and screw into stake pockets 83 that are installed into the top of the pickup truck bed sidewall 84. With this assembly technique, the weight of the upper unit 4 and the lower unit 37 are distributed along the truck bed sidewalls 83.
The handle 85 of a rachet strap is mounted to the floor 45 of the interior space of the upper unit. The strap 86 of the rachet strap passes through holes in the left side frame 25 and the aluminum channel 80, and the end of the strap 86 is connected to a factory-installed D-ring 87 within the truck bed. When the rachet is tightened, it supplies extra hold-down force to the present invention against the truck sidewalls, which reduces the load on the stake pocket bolts 82 in the event of wind loads, bumpy roads, or similar adverse conditions. The present invention may be removed from the truck by unbolting the stake pocket bolts 82 and unhooking the rachet strap 86, attaching three commercially available lift jacks (not shown) to the three jack attachment fittings 15 shown in FIGS. 1 and 3, lifting the present invention off of the truck bed sidewalls 84 with the three lift jacks, and driving the truck forward away from the present invention.
FIG. 14 is an elevation view of the control panel 49. Outlets, controls and status monitors mounted on the control panel 49 include a phone charger 88, a lithium battery charge manager 89, a light 90, a voltage inverter 91, a 115 VAC electrical outlet 92, a furnace hot air outlet 93, a thermostat 94 for the furnace and hot water heater and switch ba 95 of electrical switches. The switch bank contains on/off switches for a water pump, lights, a water tank heater and a macerator pump. The appliances operate on 12 VDC power, and this power may be optionally obtained from the truck battery or from the lithium battery. The lithium battery may be optionally charged from the solar panel 16 shown on FIG. 1 or from an external 115 VAC power source.
FIG. 15 is an elevation view of a typical quick-disconnect fitting of the type utilized in the present invention, with the quick-disconnect fitting shown in the disconnected position. This type of fitting is commercially available and is commonly described as a “cam-and-groove” hose coupling. The quick-disconnect fitting 96 is comprised of a male portion 97 and a female portion 98. A first hose 99 is connected to the male portion 97 and held in place with a first hose clamp 100. A second hose 101 is connected to the female portion 98 and held in place with a second hose clamp 102. The female portion 98 comprises an annular groove 103. The male portion comprises two cam arms 104 that are connected to internal protrusions (not shown). When the female portion 98 is inserted into the male portion 97 and the cam arms 104 are rotated inward (toward the hose), the internal protrusions of the male portion 97 grip the annular groove 103 of the female portion 98 and lock the male and female portions 97, 98 together. Rotating the cam arms 104 outward allows the female portion 98 to unlock and separate from the male portion 97.
FIG. 16 is a perspective view of the toilet cabinet 53 shown with the hinged seat top 105 in the open position. A toilet located within the toilet cabinet 53 comprises a hinged toilet lid 106 shown in the open position, a toilet seat 107 shown in the lowered position, and a toilet bowl 108.
Referring to FIGS. 1 through 14, in a preferred embodiment, the left side panel, the right side panel, the front panel, the rear panel, the rain catchment trough, the doors and ports are comprised of aluminum plate. The struts, hinges, connectors, nuts, bolts, pulleys and latches are manufactured from stainless steel. The tent is manufactured from conventional tent fabric such as canvas or polymer fiber. The interior cabinets and control panel are manufactured from wood. The cables are manufactured from polymer paracord. The tanks are manufactured from high density polyethylene or similar polymer.
The descriptions of the present invention in reference to FIGS. 1 through 14 refer to a preferred embodiment and of the invention; however, the invention may be constructed or deployed with any of the following variations:
- The lower unit may be disconnected and removed from the upper unit, and the upper unit may be used as a stand-alone “dry” camper without running water. This option provides more space in the truck bed for materials and supplies.
- The present invention may be installed on a tow-behind trailer rather than on a pickup truck.
- The present invention may be constructed with scaled-down dimensions in order to fit onto pickup trucks that have bed lengths less than 6-½ feet.
Although the preferred embodiment of the present invention has been shown and described, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from the invention in its broader aspects. The appended claims are therefore intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
