Primary Examiner-David Schonberg Assistant ExaminerTerrance L. Siemens Attorney, Agent, or Firm-G. A. Ellestad 5 7 ABSTRACT A mobile building adapted to provide shelter for such items as autos and boats has a U-shaped sill frame formed of steel tubing. Secured respectively to the middle of the two sides of the sill frame are two vertical supports which are connected at their tops by a cross bar. Sheet metal walls and a roof are carried by the sill frame with a door provided at the open end of the sill frame. Movement of the building is effected by a pair of wheels each of which is rotatable in a bracket which is pivotally mounted at the lower inner end portion of the respective vertical supports. The wheels may be moved into and out of operative position by means of an elongate lever which is secured to each bracket and adapted to be held by latching means along the adjacent support when the wheels are in operative position. Inclined tubular members secured to the inner sides of the sill frame are adapted to receive pins which are driven into the ground for anchoring the building. Detachably secured to an endof the building is a hitch having side arms which telescope into the exposed open ends of the sides of .the sill frame.

5 Claims, 3 Drawing Figures MOBILE BUILDING BACKGROUND OF THE INVENTION This invention relates to mobile buildings and more particularly it has reference to such types of buildings which are used to provide storage space or shelter for various items such as autos, boats and snowmobiles, for example. While parking spaces for autos are usually provided adjacent to mobile homes which are more or less permanently located in so-called trailer parks, there is generally no provision for garages to protect autos from the weather. Sportsmen and vacationers often need a mobile building to provide shelter for an auto, boat or snowmobile.

SUMMARY OF THE INVENTION Objects of the invention are to provide a mobile building of the type described which will be simple in structure, economical to manufacture, efficient and convenient in operation and especially adapted for the uses above mentioned.

According to the invention, a mobile building has a U-shaped sill frame formed of steel tubing. A pair of vertical supports are secured, respectively, to the two sides of the sill frame opposite each other and about midway between the ends of the sides and are connected at their tops by a cross bar. Sheet metal walls and a roof are supported by the sill frame with a door opening formed in the end wall adjacent to the open end of the sill frame and with the roof resting on the cross bar. Pivoted at the lower inner end portion of each support is a bracket on which a wheel is rotatably mounted. Secured to each bracket isa long lever by means of which the brackets may be turned to bring the wheels into position so that they support the building for movement and with the levers held in position by latching means carried by each support.

The building may be moved by attaching it to a vehicle by hitching means having two side arms which are telescoped into the open exposed ends of the sides of the sill frame and detachably held by pins. When the wheels are retracted the building rests on the ground and may be anchored thereto by inclined tubular members which are secured to the inner faces of the sill frame and adapted to receive pins which are driven into the ground.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the mobile building embodying the invention with parts broken away to show interior construction and with the wheels in operative position and the hitching means disassembled.

FIG. 2 is a fragmentary view in perspective showing the wheel mounting.

FIG. 3 is a perspective view of the means for anchoring the building to the ground.

DESCRIPTION OF PREFERRED EMBODIMENTS A preferred embodiment of the invention is shown in the drawings wherein indicates, generally,.the mobile building comprising a U-shaped sill frame 11 having the parallel sides 12 connected by an end portion 13. Secured to the respective sides 12, and midway between their ends and opposite each other, are the two vertical supports 14, which are connected at their tops by a cross bar 15. The parts of the sill frame and the vertical supports and cross bar are preferably formed of square steel tubing with the open ends of the sides 12 exposed for a purpose to be hereinafter described. In order to disassemble the sill frame 11 for convenience in handling and shipping, each side 12 may be formed of two separate pieces 16 and 17 which are detachably connected to the central piece 18 by telescoping them onto stubs 19 carried by. 18 and securing them by locking pins 20. The end portion 13 may be detachably connected to the sides 12 by similar structure.

Sheet metal walls 21 and a roof 22 are connected to and carried by the sill frame 11 with the roof 22 resting on the cross bar 15. The end wall which is at the open end of the U-shaped sill frame is provided with a door opening 23 which may be closed by a conventional overhead sliding door 24. For added convenience, a smaller door 25 and a window 26 may be provided in a side wall.

To facilitate moving of the building by towing it behind a vehicle, there are provided two wheels 27 each of which is rotatably mounted on a bracket 28 which is pivotally mounted as at 29 on the inner lowerside of each vertical support 14, as shown in FIG. 2. Secured to each bracket and extending away therefrom in a ver tical plane between the bracket and vertical support 14 is the elongate lever 30. With the wheels 27 in building supporting position, as shown in full lines in FIG. 2, the levers 30 extend upwardly along the inner faces of the vertical supports 14 and are held in such position by the latching means comprising a pivoted latch 31 which may be lowered over the end of the lever 30 and held securely by a pin 32 which passes through aligned apertures in support 14. When the building is to be located on the ground, the latch 31 is raised and the lever 30 and wheel 27 are moved to the retracted position shown in broken lines in FIG. 2 so that the sill frame 11 rests on the ground. A handle 33 attached to the upper end portion of each lever 30 facilitates the operation and the length of the lever provides a mechanical advantage so that raising or lowering of the wheels 27 may be accomplished with a minimum of effort.

With the wheels 27 in building supporting position as shown in FIGS. 1 and 2, the building may be towed by hitching it to a vehicle with hitching means indicated generally at 34 in FIG. 1. The hitching means comprises a cross bar 35 having the two side arms 36 which may detachably secured to the building by telescoping the side arms 36 into the open exposed ends 37 of the sill frame sides 12 and locking them in place by pins 38 which pass through aligned aperatures in the sides 12 and arms 36.

Since the building is relatively light in weight in order to facilitate its movement, it is desirable that provision be made for holding it in place when it is on location with the sill frame resting on the ground or on a low foundation. This is accomplished by anchoring means comprising a plurality of tubular members 39 which are secured; as by welding, at spaced intervals along the inner faces of the sides 12 and end portion 13 of the sill frame. The tubular members 39 have their axes inclined to the vertical and are adapted to receive the anchoring pins 40 which are driven into the ground.

From the foregoing, it will be apparent that the objects of the invention have been attained by providing a mobile building which is simple in structure, economical to manufacture and convenient and efficient in use. When the building is in use as a shelter, the hitching means 34 is, of course, removed so that vehicles such as an auto may be driven freely into the door opening 23 without passing over an obstructing member of the sill frame. The open ends of tubular sides 12 are exposed at both ends of the building so that the hitching means may be attached to either end of the building. Various modifications may be made without departing from the spirit of the invention as pointed out in the appended claims.
