2. Description of the Prior Art Mobile homes are generally transported to a site for remaining at the site for a fairly lengthy period of time. The wheels beneath the mobile home as well as plumbing, and ducts provide for an unattractive appearance. It is therefore desirable to provide a skirt or other covering for concealing the various items beneath the mobile home. Disclosed herein is such a skirt which is permanently mounted to the mobile home therefore not requiring installation at the time of positioning the mobile home on the site. The U. S. Pat. No. 2,755,517 issued to Sickel and the U. S. Pat. No. 3,407,548 issued to Russell disclose construction of interest.

In the prior art mobile building's, it has been the custom to mount the floor atop a frame, therefore requiring two different assemblies. Disclosed herein is a building having a unified floor-frame assembly providing for a much stronger and relatively lower cost construction. The U. S. Pat. No. 3,564,786 issued to Baker discloses a floor-frame assembly; however, the Baker patent does not disclose a floor-frame assembly which is constructed in the manner disclosed herein. The Baker patent discloses construction designed for modular segments and not a mobile building.

SUMMARY OF THE INVENTION One embodiment of the present invention is a mobile building positionable on a surface comprising a unified floor-frame assembly having a top wall and a bottom end, side walls mounted to the assembly, a wheeled carriage removably mounted to the assembly, means mounted to the bottom end operable to support the mobile home on the surface when the wheeled carriage is removed and, a skirt mounted externally to the side walls and extending to the bottom end, the skirt extending to the surface when the means supports the mobile home on the surface. v

It is an object of the present invention to provide a new and improved mobile building having a unified floor-frame assembly.

In addition to the above object, it is an object of the present invention to provide a mobile building having a skirt which conceals the means for supporting the building as well as the plumbing and the heating ducts beneath the building.

Related objects and advantages of the present invention will be apparent from the following description.

' BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of a mobile building incorporating the present invention.

FIG. 2 is an enlarged fragmentary cross sectional view taken along the line 2--2 of FIG. 1 and viewed in the direction of the arrows.

FIG. 3 is a fragmentary side view of the mobile building of FIG. 1.

FIG. 4 is a bottom plan view looking in the direction of arrows 4-4 of FIG. 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alternations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.

Referring now more particularly to the drawings, there is shown a mobile building 10 having a roof 11 and side walls 12 and 13 (FIG. 2) and end wall 14. Building 10 has a conventional hitch 15 for attachment to a vehicle for pulling the building to a site. A wheeled carriage 16 depends from the building to allow for the transportation of the building.

Building 10 is provided with a unified floor frame assembly 17 which has a plurality of lower parallel beams 18 extending across the width of the building. In one embodiment, beams 18 were produced from wood and had a rectangular cross section two inches by four inches. After beams 18 are arranged in a parallel configuration, a sheet of plastic 19 is then positioned atop beams 18 so as to extend the length and width of the building. Sheet 19 should have a minimum thickness of 0.004 inches and is provided to insulate the interior of the building from weather, mice, insects, etc. A plurality of staples 20 secure sheet 19 to beams 18. Next, a pair of parallel junior I-beams 21 and 22 are mounted atop beams 18 and are secured thereto by conventional fastening devices 23. Beams 21 and 22 extend the length of the building and are metal as compared to the remaining wooden components of the floor-frame assembly. A plurality of inverted U-shaped joists are then mounted to each lower beam 18. Each joist has a horizontally extending member 24 and a pair of downwardly extending legs 25 and 26 mounted to the opposite ends of members 24. Legs 25 and 26 extend downwardly from member 24 and are secured to beam 18 inwardly of ends 37 and 38 of beam 18. Each leg 25 and 26 extend from the lower surfaces of members 24 to the upper surfaces of beams 18. The legs are secured to members 24 and beams 18 by plywood strips 27 which are secured to the members, legs and beams by adhesives. The plywood strips extend from the upper surfaces of members 24 to the lower surfaces of beams 18 with one strip being fragmented in FIG. 2 to illustrate the positioning of leg 26. Standard fastening devices 23 secure beams 21 and 22 to members 24. Recesses 28 are provided in members 24 for receiving ribs 29, 30 and 31 which extend the length of the building. Glue is then spread on the top surfaces of members 24 and the top surfaces of ribs 29, 30 and 33. A plurality of panels 33, 34 and 35 are then layed in rows atop the members and ribs. The panels are then secured to members 24 by staples 36. In addition, screws are used to secure the ends of the panels to members 24. Spacing 32 between beams 18 and members 24 receives the necessary plumbing, heating ducts and other similar hardware.

Side walls 12 and 13 each have a plurality of parallel upstanding posts 41 and 42 which rest atop beams 51 and 51' which are secured atop ledges 40 and 39 formed by ends 37 and 38 of beams 18. Inner walls 45 and 46 are mounted respectively to posts 41 and 42 as are outer walls 43 and 44. The outer walls extend from the roof of the building down to a position adjacent to the panels 33, 34 and 35. Skirts 49 and 50 extend from the lower edge of outer walls 43 and 44 to a position immediately adjacent the lower ends of beams 18. The skirts are also mounted to posts 41 and 42. The skirts are thereby permanently mounted externally to the side walls and extend to the bottom end thereof. Sheet 19 extends upwardly between leg 26 and post 41 and between leg 25 and post 42. Ribs 47 and 48 are seated in recesses formed in posts 41 and 42 and extend the length of the building being secured respectively to legs 26 and 25.

Two wheel wells 52 and 53 are provided in the floorframe assembly for receiving the wheels of wheel carriage 16. Each wheel well is identical having an upper wall 54 secured to members 24 and end walls 56 secured to members 18. The side walls 55 and 57 of each wheel well extend through members 18. Wheel axles 59 extend from one wheel well to the other wheel well rotatably mounting the wheels to leaf springs 58. The leaf springs are mounted to metal beams 90 which in turn are pinned by standard fasteners 81 to tubing 91 secured to the bottom of I-beams 21 and 22. Additional tubing 9297 is mounted to l-beams 21 and 22 being parallel therewith and extending beneath beams 18. Tubing 9197 supports the building above a surface when the wheel carriage is removed. The tubing is welded to the l-beams.

Hitch 15 has a metal beam 101 with a conventional trailer hitch ball coupling (not shown) thereon for connecting to the towing vehicle. Beam 101 is welded to and beneath metal channels 100 which fit onto metal beams 98 and 99 secured to the bottom of l-beams 21 and 22. Channels 100 and beams 101 are not shown in FIG. 4 for sake of clarity.

By pinning the wheeled carriage to the tubing, the carriage may be quickly and easily removed and returned to the manufacturer for the transportation of another mobile building. The tubing secured to the lbeams alleviate the necessity for mounting the mobile building atop cement blocks since the building may be set immediately atop a slab being supported by the tubes. When the wheeled carriage is removed from the mobile home, the skirts extend down to the slab concealing the plumbing, etc., beneath the building.

While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
