EXPANDABLE HABITATION UNIT WITH SLEEPING
COMPARTMENT
TECHNICAL FIELD
The present relates to recreational vehicles having temporary habitation units, and more particularly to an expandable temporary habitation unit with an enlarged usable living space including a separate sleeping compartment.
BACKGROUND
Recreational vehicles (RVs) including motor homes, travel trailers and caravans are now commonplace. They provide families with an opportunity to drive to locations of interest and have immediate access to living quarters upon arrival. The flexibility provided by such temporary living spaces are such that the users do not pay hotel fees, they are close to nature, and leave little in way of carbon footprint. While this seemingly simple way of living has many advantages, RVs and caravans have a number of signifcant drawbacks, which can hamper the full enjoyment of their use. The most common problem is providing a living space that is both functional and sufficiently large so that the users do not feel cramped whilst inside. When RVs are increased in size for more living space, then they become large, cumbersome and more difficult to handle. Also fuel costs increase due to additional weight and poor areodymanics.
To address these problems, a number of RVs have been designed, which provide extensible slide-out units for increasing the vehicle's living space. This slide-out unit may be extended for use when the vehicle is parked and is retracted in a telescoping mariner when the vehicle is to be moved. Examples of such designs are given below.
US Patent No. 7,802,834 for "Multiple slide-out room for a recreational vehicle" to Cadena et al on September 28, 2010 discloses multiple slide-out system for a recreational vehicle or the like includes a first slide-out section having a first floor, a first carriage abutting and affixed to the first floor, a first driven track affixed to the underside of the first carriage, and a first drive motor anchored to the floor of the vehicle to drive the first slide-out section relative to the vehicle. A second slide-out section which slides within the first slide-out section includes a second floor, a second carriage abutting and affixed to the second floor, a second driven track affixed to the underside of the second carriage, Docket# 133-P02.WO

and a second drive motor anchored to top side of the first carriage to drive the second slide-out section relative to the first slide-out section. The driven tracks do not extend underneath the portions of the slide-out section floors that will be visible from the outside of the vehicle when the system is in its extended position, thereby presenting a clean and generally smooth appearance when viewed from the outside.
US Patent No. 7,226,116 for "Recreational vehicle full wall slide-out" to Jones on June 5, 2007 discloses a mobile recreational vehicle, which includes a body enclosing a living area designed to serve as self-contained living quarters during recreational travel. The body is supported on at least one pair of wheels (and often two or more pairs). The vehicle includes a ceiling assembly, a floor assembly; and an elongated and adjustable ceiling support extending between the ceiling assembly and the floor assembly wherein the height of the support can be adjusted during installation. In some instances, the vehicle has a shortened full length slide-out to allow for additional sidewall ceiling support, and in some instances has a slide-out opening that has cambered upper edges to minimize sagging the opening.
US Patent No. 6,527,324 for "Adjustable slide-out room for mobile living quarters" to McManus et el on March 4, 2003 discloses a recreational vehicle, which includes structure defining side walls of a main living unit mounted on a frame and a slide-out room which extends and retracts through an aperture in one of the side walls.
Adjustments are provided to adjust the angular orientation of the slide-out room without respect to the side wall of the main living unit, to adjust the vertical position of the slide-out room in the extended position and to adjust the tilt of the slide-out room. Further adjustments are also provided to adjust the position of the back wall of the slide-out room in the retracted position to assure that trim and decals applied to the side wall of the unit and extending over the back wall of the slide-out room are properly aligned.
US Patent No. 5,491,933 for "Flat floor slide out apparatus for expandable rooms" to Miller et al on February 20, 1996 discloses an expandable room structure, which has relatively movable room portions supported by telescopically sliding tubes, at least one of those tubes being movable also laterally to pivot as the room portion floors slide into the same horizontal plane when the room structure is moving into expanded positions. In retracted positions the room portion floors are vertically spaced to permit one room

Disadvantageously, some of the designs described above include an extension/retraction system that relies on screws or a pinion for provide telescoping movement of the slide-out unit relative to the vehicle. If screws are used, they must be short for practical reasons because longer screws deform so that the axis of the screw is not linear. If pinions are used, they too must be short. Since the amplitude of movement of the slide-out room or compartment can be no greater than the length of the screw or pinion, the amplitude of sliding movement, and hence the amount of additional space gained by the slide-out compartment, is limited.
Other types of slide-out units use an endless cable which passes over a pair of pulleys which is supported by a main part of the mobile home and another pair of pulleys mounted on side walls of an extension part of the mobile home cause the extension part to reciprocate. Another slide-out installation shows an expanding unit which includes a rotatable shaft and two types of cables wound around the shaft. Rotation of the shaft in one direction causes one type of cable to wind as the other type unwinds, causing a second module to reciprocate in one direction relative to first module.
Rotation of the shaft in the opposite direction causes the second module to move in the opposite direction.
A major problem that hampers the use of slide-out units is that of cantilevering as the unit extends. The outer end of the extended slide-out unit tends to tip downwardly, which places weight on the slide-out unit's operating mechanism. The cantilevered slide-out unit also tends to cause looseness at the top, which in turn causes tightness at the bottom. This puts weight on the slide-out mechanism, which in impairs slideability and causes leakage around the joints.
Common to all previous designs is the limited amount of exterior envelope that is possible to expand for additional living space. The structural intergrity of the envelope is comprised as more holes for pop-out sections or moveable roofs is made.
Thus, there is a need for an improved temporary habitation unit, which provides a larger living space yet maintains structural intergrity.

BRIEF SUMMARY
Generally speaking, a Recreational Vehicle (RV) provides limited space for comfortable temporary living. Typically, RVs comfortably sleep from two to four people, depending on the size of the RV. I have a designed a temporary, expandable living unit that substantially reduces, or improves upon, the problems described above in the previous designs. My unit addresses the problems by using a novel and non-obvious structural frame with a piston and guide arrangement which when in operation provide a user with a living space that is substantially larger than those described above because a roof module, a rear module and two side modules are all fully deployed so that the total habitation area and volume are significantly increased. In other words, the entire exterior shell of the habitation unit is deployed to create additional living space, contrary to other designs in which only partial sections of the exterior shell are displaced for additional living space.
The piston, guide and frame arrangement allows the floors of the three individual living modules to slide over the main floor in three opposing directions and the roof module to move vertically in such a fashion as to considerably increase the interior volume and accessible floor area. This is possible due to the rear module exterior walls partially overlapping the two side modules exterior walls in the default closed position, which are partially overlapped again by the roof module (double overlapping), thus allowing considerable compression of space from the larger opened position to the closed position.
When the living modules are locked in place in the open configuration by the roof module and supporting structural frame, the problems of cantilevering which plagued many of the known designs are addressed. Advantageously, my unit can be retrofitted onto an existing motorised vehicle subframe or it can be used as a stand alone unit that can be hitched to the back of another vehicle. I have also designed a novel and unobvious expandable habitation unit for use with an RV in which I have also converted the unused space above the driver's cabin into a sleeping berth for an additional person. To achieve this, I have designed a roof in which the front part of the roof sidewall flares out so as to be flush with the driver's windshield to preserve the aerodynamic qualities of the RV
when the roof is in the closed configuration. I have included an accordian-like seal at the junction between the front sidewall and the top of the cabin above the windshield and doors.
When the roof is moved upwardly, the seal expands to allow a person to then have access to the sleeping berth.

Although not shown, a similar roller system is located between the main floor 84 and the other module floors, i.e. rollers 148 are located between the rear module floor 92, the second side module floor 124 and the main floor 84 to permit rolling movement of the module floors over the main floor. Thus, the module floors 92, 108, 124 overlap the main floor 84 when the habitation unit 10 is in the closed configuration, and move over the main floor 84 to achieve the open configuration. The roof module 24 overlaps the modules 18, 20, 22 in the open configuration and also overlaps the modules 18, 20, 22 in the closed configuration.
Referring now to FIGs 9, 10, and 11, the roof module 24 is connected to the main frame 28 to permit movement along a fourth restricted path of travel. The roof module 24 is sized and shaped to cover and partially overlap the rear module 18, the first side module 20, the second side module 22 and the main floor 84. In the example illustrated, the roof 24 is generally flat with a peripheral sidewall 140 which depends downwardly therefrom such that in the default configuration, the roof module 24 is coplanar with the RV cabin 14. It is desirable to have the habitation unit 12 with a habitation volume that is sufficiently large to permit an enjoyable, non-cramped environment in which to, for example, cook, sleep, eat and bathe. To this end, the habitation volume of the habitation unit 12 is defined by how far apart the roof module 24, the rear module 18, the first side module 20 and the second side module 22 are displaced. The novel and unobvious design of the habitation unit 12 permits the user to vary the size of the habitation volume from the overllapped closed default configuration to the open configuration.
Typically, as seen in FIG. 7, the first open configuration is for use during the day in a stationary position, where maximum available space is required. As best illustrated in FIG. 8, a second open configuration of the habitation unit 12 is typically for use during the night when the first and second side module can be converted into sleeping areas using pull-out beds.

In FIG. 15, the first and second side modules 20, 22 are shown in the open and closed overlapping configuration relative to the main frame 28, and the roof module 24 shown in the open and closed overlapping configuration relative to the main frame 28. Furthermore, in FIG. 15, a dual gasket system 142 and permits water drainage and reduced or prevented water penetration.
As illustrated above, the habitation unit 12 is designed for use with the RV
10. Referring now to FIGs. 16, 17 and 18, for users who merely wish to attach a habitation unit to an existing vehicle an alternative, free-standing habitation unit is illustrated generally at 200.
The free-standing unit 200 can be hitched to a vehicle using a hitch extension 202 of a main frame 204. The habitation unit 200 is essentially identical to the habitation unit 12 described above, but now includes a front module 205. The salient differences between the two units will now be described. The hitch extension 202 extends away from the main frame 204 and is generally triangular. A central stabilizing connecting shaft 206 is connected to a front cross bar 208 of the main frame 204. The unit 200 includes a front outer wall 210, which includes two curved corners 212, 214. This outer wall provides an additional habitation area 216 over the hitch extension 202. The habitation unit 200 is operated using a remote control panel (not shown).
Referring now to FIGs 20A and 20B, as an additional stabilizer, each of the side modules 20, 22 includes a stepped stabilizing member 300, 302, which are extensions of the stepped first and second side module roof 118, 134. The stepped stabilizing members 300, 302 run substantially the entire length of each side module 20, 22. As best illustrated in FIG. 20B, in the open configuration, the stepped stabilizing members 300,
- 23 -Docket# 133-P02.WO

302 are disposed generally orthogonal to the ground, to abuttingly engage the main frame 28. The peripheral sidewall 140 of the roof 24 rests on the stepped first side module roof 118, and the stepped second side module roof 134. This provides lateral stability to the side modules 20, 22, and significantly reduces, outward rotation of the side modules 20, 22. In the closed configuration, as best illustrated in FIG. 20A, the stepped stabilizing members 300, 302 are in the default position.
Additional sleeping berth Turning now to the problem of sleeping room for passengers. For the RV 10, as illustrated throughout, the side modules 20, 22 typically provide comfortable sleeping room for about two to four adults, depending on their size. Referring now to FIG. 21A, FIG. 21B, FIG. 21C, FIG. 22 and FIG. 23, to take full advantage of every available space, I have now designed a sleeping compartment 400 by modifying the area above a cabin 402 of the RV 10. The RV 10 includes the cabin 402 with a ceiling 404, two doors 408, seats 410, a windshield 412, and the expandable habitation unit 12 located behind the cabin 402.
Referring specifically to FIGs 22 and 23, a roof module 414 is sized and shaped to cover both the expandable habitation unit 12 and the cabin 402. As with the roof module 24 described above, the roof module 414 includes a peripheral sidewall 140, which depends downwardly therefrom. The peripheral sidewall 140 of the roof module 414 includes a front roof portion 416 and a rear roof portion 418. The roof module 414 is actuatable between a closed configuration and an open configuration. When the roof module 414 is fully extended to achieve the open configuration, the sleeping compartment 400 is sufficiently large to accommodate one person. The sleeping compartment 400 includes a sleeping berth 420, which is separate from and independent to the expandable habitation unit 12. The sleeping berth 420 has a sleeping surface 422 located on top of the ceiling 404. The front roof portion 416 is moveably connected to the cabin 402 above the windshield 412 and the doors 408 to permit movement of the roof module 414 between the open and closed configuration. The front roof portion 416 is sealingly connected to the cabin 402 using an expandable connector 424. In the example shown, the expandable connector 424 is an accordion-like connector, which is typically made of rubber or silicone. The expandable connector 424 can be any type of expandable connector known

This provides lateral stability to the side modules 20, 22, and significantly reduces, outward rotation of the side modules 20, 22. In the closed configuration, as best illustrated in FIG. 20A, the stepped stabilizing members 300, 302 are in the default position.
Additional sleeping berth Turning now to the problem of sleeping room for passengers. For the RV 10, as illustrated throughout, the side modules 20, 22 typically provide comfortable sleeping room for about two to four adults, depending on their size. Referring now to FIG. 21A, FIG. 21B, FIG. 21C, FIG. 22 and FIG. 23, to take full advantage of every available space, I have now designed a sleeping compartment 400 by modifying the area above a cabin 402 of the RV 10. The RV 10 includes the cabin 402 with a ceiling 404, two doors 408, seats 410, a windshield 412, and the expandable habitation unit 12 located behind the cabin 402.
Referring specifically to FIGs 22 and 23, a roof module 414 is sized and shaped to cover both the expandable habitation unit 12 and the cabin 402. As with the roof module 24 described above, the roof module 414 includes a peripheral sidewall 140, which depends downwardly therefrom. The peripheral sidewall 140 of the roof module 414 includes a front roof portion 416 and a rear roof portion 418. The roof module 414 is actuatable between a closed configuration and an open configuration. When the roof module 414 is fully extended to achieve the open configuration, the sleeping compartment 400 is sufficiently large to accommodate one person. The sleeping compartment 400 includes a sleeping berth 420, which is separate from and independent to the expandable habitation unit 12. The sleeping berth 420 has a sleeping surface 422 located on top of the ceiling 404. The front roof portion 416 is moveably connected to the cabin 402 above the windshield 412 and the doors 408 to permit movement of the roof module 414 between the open and closed configuration. The front roof portion 416 is sealingly connected to the cabin 402 using an expandable connector 424. In the example shown, the expandable connector 424 is an accordion-like connector, which is typically made of rubber or silicone. The expandable connector 424 can be any type of expandable connector known

to those skilled in the art. In the open configuration, the expandable connector 424 is disposed generally orthogonal to the sleeping surface 422. In the open configuration, an access opening 426 is located rearwardly of the sleeping berth 420. The access opening 426 is sized to permit a user to move into and out of the sleeping berth 420.
To maintain a level of privacy for the occupant, the access opening 426 separates the expandable habitation unit 12 from the sleeping berth 420.
Referring now to FIGs 21A and 22, in the closed configuration, the front roof portion 416 is disposed coplanar with the windshield 412 to create an aerodynamic surface so as to reduce drag on the RV when it is moving.
Referring again to FIGs 22 and 23, the spaced apart roof actuators 68, 70, 72, 74 are essentially identical to those described in FIGs. 9, 10 and 11 above. The two front actuators 72, 74 when extended fully in this design are longer than the actuators described above, to account for the height of the sleeping compartment 400, and to provide the sleeping compartment with sufficient volume so that the occupant does not feel claustrophobic. In the examples illustrated, the actuators 64, 66, 68, 70, 72, 74, 76, 78, 80, 82 are, without limitation, hydraulic pistons which are operably connected to the control panel so that they can received commands therefrom. A person skilled in the art will recognize that different types of actuators can be used, for example, worm gears, sprocket and gear and the like.
The habitation unit 12 in this design is essentially identical to that described above, and as such will not be described in detail here other than to say that the two side modules 20, 22, the rear module 18, and the roof module 414 are moveable along respective restrictive paths of travel and that the roof module 414 is connected to the main structural frame by actuators to permit movement along a restricted path of travel such that in the closed configuration, the roof module 414, the modules 18, 20, 22 and the sleeping berth 420 define a first habitation volume. The roof module 414 is moveable along the roof restricted path of travel orthogonally relative to the respective restricted paths of travel of the modules so as to vary the size of the first habitation volume. In response to a first user command, the actuators move the modules away from each other in sequence along their respective restricted paths of travel from a default overlapped closed habitation configuration to an open configuration.

Operation Referring now to FIGs. 19A through 19D, there will now be described an operation of the habitation unit 12. The operation of the alternative habitation unit 200 is identical to that of the unit 12, and will not be described. In the example illustrated, the control panel is located in the cabin 14. The controller can be an on-board computer, a remote control device operable using WiFi, BluetoothIm and the like. In the free-standing design 200, the controller can be a hand-held electronic device such as a smartphone, a tablet, and the like, which the user uses to control the habitation unit 12. For the stand alone design 200, the central control panel could be fixed to the hitch extension 202 or integrated into one of the modules.
Broadly speaking, the main frame 28, the rear module 18, the first side module 20, the second side module 22 and the roof module 24 are each interconnected to at least two of the actuators described above such that in response to a first user command given at, for example the control panel, the actuators moves the modules away from each other in sequence (roof module moves first followed by the rear module then followed by both side modules) along their respective restricted paths of travel from the overlapped default closed habitation configuration to an open configuration. When desired, the controller issues a second user command so that the main frame, the rear module, the first side module, the second side module and the roof module are each interconnected to at least two actuators such that in response to a second user command, the actuators move the modules towards each other in sequence (both side modules move first followed by the rear module then the roof module) along their respective restricted paths of travel from the open configuration to the overlapped closed configuration coplanar to the cabin 14.

second side modules closed and locked. An interlock with the engine/transmission prevents the opening sequences when driving the vehicle.
Once stopped and parked, the vehicle is leveled with four jacks, one in each corner. The leveling is carried out automatically from the control panel. The jacks are operated by actuators, which can be hydraulic or mechanical. The modules are then unlocked. The opening sequence is as follows with reference to FIGs. 19A through 19D.
Firstly in FIG. 19A, the roof module 24 is first opened to a maximum height position by the four actuators, one in each corner of the main structural frame in the direction of the arrows shown.
Second in FIG. 19B, the rear kitchen module 18 is opened to maximum position in the direction of the arrows. It is supported and guided by the two guide rails below the floor level. The two actuators push the lower frame of the rear module outward. The floor of the module is also supported by rollers on the edge of the main rigid RV floor 84.
Third in FIG. 19C, the two dining/bath and living side modules open simultaneously outward to maximum position in the direction of the arrows until the roof upright 302 stops at frame 28. They are each supported and guided by the two guide rails below the floor level. The two actuators per side module push the lower frame of the modules outward. The rollers 148 on the edge of the rigid RV floor 84 also support the floor of each side module.
Fourth in FIG. 19D, the roof module 24 is lowered in the direction of the arrows to overlap and sealingly rest on the three lower module roofs.
Finally, the modules are then locked together to secure the unit and prevent movement between modules and reduce the effects of cantilevered modules.
To close the RV and get ready for driving, the sequence is reversed by raising the roof module 24, then moving the side modules 20, 22 towards each other to be coplanar with the cabin 14, then moving the rear module 18 towards the side modules with partial overlapping of the side walls and then finally lowering the roof module 24 to partially overlap the three lower modules 18, 20, 22. At the junction of the modules 18, 20, 24 and 18, 22, 24 there is double overlapping of the exterior envelope walls.
