For the purpose of illustrating the invention, the drawings show aspects of one or more embodiments of the invention. However, it should be understood that the present invention is not limited to the precise arrangements and instrumentalities shown in the drawings, wherein:
A wheelchair accessible home addition system is provided that includes a trailer, a prefabricated dwelling unit, and a connector, which together allow for the rapid installation of a wheelchair accessible bedroom and bathroom with an optional kitchenette that can be temporarily or permanently attached to an existing home. A more temporary installation may be accomplished using the trailer assembly, which includes four integral crank-down support jacks that can be engaged and secured for hurricane winds with cable tie downs. In this way, the dwelling remains on the trailer during use. A more permanent installation may be accomplished by using a metal support frame under the dwelling that allows the dwelling to be placed on a site built pile foundation, in which case the trailer can be towed away for reuse.
The dwelling unit, is suitable for individuals requiring care and/or having mobility issues, is portable and can be removably connected to an existing structure, such as a residence, to allow direct access to the existing structure while remaining on the trailer or on the pile foundation. In this way, the home addition may serve as an alternative to making construction modifications to a residence to accommodate another individual, especially one requiring care and/or having mobility issues, since many existing residences are not designed to accommodate those requiring care and/or having mobility issues.
The dwelling unit can be made directly accessible through a connection to the existing structure thereby allowing occupants of the existing structure, or host house, to easily and conveniently get to the dwelling unit while affording the patient a sense of privacy and independence. The home addition also allows the occupants of the host house to minimize any disruption and inconvenience associated with adapting the existing house to meet the needs of the patient and having a patient in the home while maintaining the peace of mind that having the patient on premises provides.
The home addition may include electrical connections to the existing structure as well as a plumbing system. Additional features may include an integral hoist system, unibody construction, portable ramp and decking, and a weather-tight, adjustable connector between the living facility and the host house.
Alternatively, as shown in
The wheel assembly as well as stabilization jacks of trailer 104 are continuously welded to the chassis. Optionally, trailer 104 may include a removable trailer hitch tongue that can be secured to either side of trailer 104 to facilitate easier installation near the host house.
Unit 102 may be constructed to be practically squeak free by using a unibody construction that allows the chassis, floor, walls, and roof to effectively act as one piece. The integral bond between these elements is achieved with a redundant application of mechanical fasteners and a continuous application of structural adhesives. In particular, with reference now to
Wall plates 116 are secured to wall panels 120 (e.g., 120a-120d), which may preferably be structurally insulated panels, with structural adhesive and continuous panel overlap on both the interior and exterior faces of the wall, which is twice the overlap found in typical construction of manufactured housing where panel overlap only occurs on the outside of the plate. This Structural Insulated Panel construction is also known as a “SIP” construction and structurally insulated panels in accordance with such construction may be manufactured as an engineered assembly of insulating foam with two panels of Oriented Strand Board (OSB), structurally laminated to both broad surfaces. SIP panels can be obtained from a number of vendors such as, Foard Panel, Inc. of Chesterfield, N.H. The continuous panel overlap on both the interior and exterior allows wall panels 120 to be secured continuously to wall plates 116 on both sides of wall panels 120. Wall panels 120 are also mechanically fastened one to the other and adhered with joint cavities that are foamed in place with a high strength insulating adhesive foam.
The unitized wall panel 120 and one piece floor panel 108 assembly is further solidified by attaching a single continuous roof panel 124 to the tops of wall panels 120. This provides a rigid structural diaphragm at both the top and bottom of unit 102. This utilization of a continuous structural skin on the interior and exterior strengthens the unibody construction. All construction corners and seams are secured with separate interior and exterior mending plates that eliminate thermal bridging.
A back vented siding may be applied to continuous wood members that surround all sides of unit 102. As shown in

A second area 156 serves as a bath area and may include privacy glass panels 158 to separate the bath area from the bedroom, although it will be understood that other materials may be used to provide this separation. Glass panels 158 may be frosted from the floor up to the top of an interior door 160, which may preferably be a standard height of eighty inches or run from floor to ceiling to accommodate a hoist track (discussed below). Above standard, door height, the glass may be transparent to visually extend the ceiling lines from both areas and maximize the apparent size of each area.
The bath area includes a roll in shower area 164 that uses an integral floor drain 168. The drainage area may be created with a shower drain pan that tapers on four sides. A continuous non-slip floor finish covers the entire shower area 164 and slopes down seamlessly to drain 168. The same flooring flashes up the walls surrounding shower area 164 with a gentle 1.5″ radius curve known as a “cove stick” for hygienic purposes The bath area may also include amenities such as a glass grab rail 172 to enhance the interior environment to provide a welcome distinction to the institutional look and feel of hospitals and rehabilitation centers. It will be understood that any suitable grab rail may used, including clear acrylic, for example. Glass grab rail 172 may use laboratory glass billet rods held in place with finished metal hardware and can be finished with custom polished ends and miters where they meet at the corners. In addition, a glass and zinc basin 176 may enhance the interior environment to provide a welcome distinction to the institutional look and feel of hospitals and rehabilitation centers. It will be understood that other materials may be used for basin 176, such as porcelain.
A sink 180 is designed and attached to the plumbing wall such that sink 180 cantilevers over the floor and thus provides wheelchair access from the two open sides, as can be seen in
Sink 180 drains into a stainless steel drain trap that may be concealed under a grate 184, which may be made of teak wood or other suitable material. A chase wall 188 to which sink 180 is attached conceals the mechanical, electrical, and plumbing lines while at the same time facilitating via removable panels easy access to the plumbing, as well as a bath fan.
An integral hoist track system may be included within unit 102 to assist with the mobility of the patient. With the above described unibody construction of unit 102, supplemental bracing may not be necessary to support the hoist track system. This allows for an economical alternative to costly track systems that require special structural bracing before they are installed. The purpose of the hoist track system is to assist in the conveyance of an occupant from the bed to the shower, for example. It is noted that the hoist system may be used by a patient to transport them to any area of a wheelchair accessible home addition. The hoist track system, an exemplary path 192 for which is outlined in
When portable dwelling unit 102 can be placed near a host house, connector 140 may allow direct access between dwelling unit 102 and the host house. Connector 140 is weather-tight and insulated and, in additional to allowing people to go directly between the host house and dwelling unit 102, can carry the mechanical, electrical, and plumbing services to/from the host house to/from the home addition.
When home addition 100 is connected to a host house, connector 140 may include an exterior door 132 (shown in
When a door of the host house is not available or practical, a window opening may be modified such that a portion of the wall below the window sill is removed temporarily to create direct access through connector 140 while home addition 100 is in place.
Unit 102 is energy efficient due to the continuous insulation available through the use of Structural Insulated Panel construction, as well as preferably in some embodiments through the use of insulation in the floor and ceiling.
Other features of home addition 100 may include the use of corrugated metal as a special lightweight finish in the bathroom and to hide the hot water heater. Fasteners securing these finishes are easily released to provide easy access to the plumbing walls. Latex reinforced tile adhesive may be used as a lightweight wall finish applied as a finish stucco directly over the wall sheathing. Fire treated wood finish thin veneer plywood may be used as a wainscoting. In addition, fire treated rough sawn wood ceiling panels may be used to conceal wiring and provide a unique natural material finish.
In another exemplary embodiment, as shown in
At a location where dwelling unit 304 is to be installed, which is typically near an existing building or residence 342 as shown in
As shown in
Connector 302 is installed (as shown in
Thus, in an exemplary embodiment, a connector may be quickly and inexpensively installed across a variable distance using telescoping metal scaffolding support members to make up a telescoping connector floor, sides, and roof having gaps not less than two inches to allow for a wire or plumbing chase. The inside finish will provide a clear five foot width throughout the connector. The interior length can be telescopically adjusted from, for example, 5 to 9 feet. A layer of ¼ inch thick birch veneer plywood wainscot wall panels can be used to repeat a similar scallop design that can be used in the bedroom area. The ceiling can be finished with a continuous layer of fire treated black burlap wrapped over the exposed face of one inch mineral wool boards that are mechanically fastened with wall washers to strapping between the gaps of the telescoping scaffolding assemblies. The exterior finish may have exterior continuously applied insulation, such as three inch thick fire resistant foam insulation polyisocyanurate boards with taped joints on all four exterior faces of the connector. The roof can include an additional curved one inch thick foam board bent over a one inch centered 5/4×2 blocking top to create a slight barrel vaulted one inch height in the center. This will be topped with a single ply fully adhered membrane roof applied over the foam and wrapped over the top wall fascia with a metal drip. The exterior wall and bottom plane will be faced with a horizontally applied wood 1×3 finished applied over rain-screen strapping. Alternatively, the connector may be supported on a plurality of posts.
If access is desired to the existing building through the opening enclosed by the connector without the need to go through the dwelling unit, the connector may include an exterior door on one or both of the sidewalls. An entry ramp, stoop, or steps may be added in front of such a door as needed.

One or more blocks 432 (e.g., 432a-432c) may be disposed between track framing 424 to further stabilize the system. Hoist system 392 includes a rail track 436 that is disposed between track framing 424 and may be further secured by a screw 426 or similar engaged through blocks 432, and preferably screw 426 does not extend past block 432a. Rail track 436 supports a hoist engagement member, such as a nylon wheel truck assembly 440, that conveys along rail track 436. Truck assembly 440 is connected to a lift 444 via any suitable component such as a carabiner 448. Preferably, track framing 424, rail track 436, and truck assembly 440 are substantially located above ceiling 388 to provide a less industrial appearance. In addition, hoist system 392 may include a rope (not shown) or similar mechanism that allows an occupant of lift 444 to move between the bedroom area and the bathroom area simply by pulling on the rope. In this way, a built-in hoist track system is provided for a fraction of the cost of conventional systems.
