DETAILED DESCRIPTION

[0030] The invention is described as a small camper suitable for attachment to a hitch receiver on a vehicle. A characteristic of the present invention is that it employs a support bar that is inserted in the hitch receiver, the bar extends rearward of the hitch receiver, the small camper has a receiver means underneath the camper floor for straddling or surrounding the support bar. The small camper is attached to the bar and held in a horizontal transport position having substantial ground clearance above the road surface.

[0031] In a preferred embodiment of the present invention, a vehicle attached camper includes a rigid rectangular floor supporting a collapsible/expandable portion. The camper walls and roof are not constructed of canvas but are constructed of a rigid material. The camper when erected into its sleeping position creates an enclosure of a size and shape suitable for sleeping at least one adult. The collapsible/expandable portion includes two pivotally mounted half shells located near the opposite ends of the central rectangular floor. Each half shell includes a sidewall and an angled roof portion. The two half shells are pivotally attached to the floor and can be quickly erected into a sleeping position from a collapsed travel position. The erected camper half shells together form a triangular arch roof and two vertical sidewalk. A base wall extends vertically upward from the rear edge of the floor. A front entrance is located on the opposite side of the rear wall. The entrance is defined in part by two symmetric front base walls extending vertical upward from the floor. The rear gable wall and front wall panels are hingedly interconnected with their respective base wall sections and arranged to be folded into a short collapsed position. Referring to FIG. 1, reference number 10 is a vehicle, a pick-up truck. The present invention camper is fastened to the vehicle. Numeral 20 designates the camper of the present invention in its erected sleeping position. Camper 20 includes a rigid rectangular floor 22 for supporting a collapsible/expandable portion. The collapsible/expandable portion includes two pivotally mounted half shells 24, 26, as best shown in FIG. 3, attached at opposite far ends of the rectangular floor 22. Each half shell 24, 26 includes a sidewall 23, 25 and an angled roof portion 27, 28. The two half shells 24, 26 can be pivoted between a sleeping position as shown in FIG. 1 and a compact collapsed position as shown in FIG. 2. The sidewall 23 and roof 28 of the half shell 24 are slightly wider than the width of the sidewall 25 and roof 27 of half shell 26, so that half shell 24 may substantially envelope half shell 26 when the camper is in the compact collapsed position.

[0032] From the collapsed position the two half shells 24, 26 can be quickly erected into a sleeping position, as shown in FIG. 1, by pivoting the two half shells outward from the central vertical axis of the camper. To facilitate the pivoting of the half shells as aforesaid, any satisfactory handle means may be secured to the sidewalls 23, 28 for assisting in lowering and raising the half shells between their sleeping and travel positions. In the sleeping position, as shown in FIG. 1, the camper half shells together form a substantially triangular arch roof, two vertical sidewalls 23, 25, and bottom surfaces 37, 38. The bottom surfaces 37, 38 in the erected sleeping position cooperate with the central floor 22 to form a substantially even horizontal surface from one sidewall 23 to the other sidewall 25. The half shells further comprise of rear wall 33, 34 sections and front wall sections 31, 32.

[0033] The camper half shells are positioned at opposite ends of the floor and when the camper is in the sleeping position both half shells roof portions extend to near the central vertical axis of the camper. As illustrated in FIG. 1 the far end roof portion of half shell 24 extends across the central vertical axis so as to slightly overlap the roof portion of half shell 26. Conventional abutment surfaces are employed to properly locate and position the two half-shells 27, 28 in the erected position. A roof top portion 29 of the triangular arch roof forms an uppermost flat horizontal surface.

[0034] Suitable connection means such as hooks, sliding bolts, latches or other well-known means in the art may be employed at the uppermost roof top to fix the two half shells 24, 26, together when in the sleeping position. See U.S. Pat. No. 2,626,832 (Guthoerl) which is incorporated herein by reference in its entirety. Also see U.S. Pat. No. 4,027,912 (Pacca) which is incorporated herein by reference in its entirety. Similarly, other well-known connection means maybe employed to fix the two half shells 24, 26 together when the camper is in the compact collapsed position of FIG. 2 so that the camper does not become unfolded as it travels down the roadway.

[0035] Roof sections 27, 28 have weatherstrips 35 on both their forward and rearward border edges. The upper ends of front wall panels 52, 53 and upper end of rear gable wall 51 substantially abut against weatherstrips 35 when the camper is in its sleeping position. The inside surfaces of the weatherstrips 35 may include resilient seals to help maintain a more comfortable environment inside the camper. In the collapsed position half shell 24, is arranged on top of half shell 26, the weatherstrips 35 assist in aligning and maintaining shells 24, 26 together.

[0036] All joints and/or abutment surfaces between half shells and wall portions, or wall portions with other wall portions and/or weatherstrips may be provided with suitable seals means well-known in the art. In a preferred embodiment, an inner flange or groove may be provided adjacent the outer extremity of top portion 29 for cooperation with a liquid tight resilient seal near the extremity of roof section 27. In a preferred embodiment a rainproof camper may be achieved by adopting thin sealing strips of foam rubber or foamed plastic material cemented along appropriate edges or surfaces about the entire camper.

[0037] Base walls 41, 42, 43 extend vertically upward from floor 22. A front entrance (not numbered) is centrally located on the opposite side of the rear base wall 41. The entrance is partially defined by two symmetric front base walls 42, 43 extending vertically upward from the floor 22.

[0038] A rear gable wall 51 is pivotally connected to the upper extremity of the rear base wall 41 by hinge means (not numbered), and front wall panels 52, 53 are pivotally connected to the upper extremity the front base walls 42, 43 respectively. The gable wall portion 51 and two front wall panels 52, 53 can be manually folded inward into a short collapsed position,

[0039] The rear gable wall may not have windows or may have windows (not numbered) as illustrated in FIGS. 1 and 3, the window may be formed from a transparent plastic material. The front entrance may be provided with a swinging gate (not shown) between the front base wall sections 42, 43 for limiting access into the camper.

[0040] Once the aforesaid half shells are rotated and fixed into the sleeping position, the folded over rear gable wall 51 can be simply erected by pivoting it about its hinges into a vertical position. Next the front panels 52, 53 can be manually rotated up into their vertical positions. After each of the structure parts 24, 26, 51, 52, 53 is rotated into its sleeping position they may be provided with manual connecting means to secure these structure parts of the camper in place.

[0041] As seen in FIG. 1, the camper has support legs 44 for supporting for the camper on the ground. The support legs are pivotally connected to the underside of the floor. Preferably there are four adjustable support legs attached near the four corners of the central rigid floor to provide for better stability of the camper. Each support leg has an upper receiving member which in a preferred embodiment may be made from two-inch square rectangular steel tubing having two juxtaposed drilled through holes along its entire length, the support legs have lower telescoping members sized to be telescopically received in their respective upper members. The lower members of the supporting leis likewise have a series of vertically disposed drilled through holes along their entire length. Each leg has a height adjustment pin that is insertable into cooperating aligned holes of the upper and lower member. Whereby the level of the foot 45 on a leg can be raised or lowered to conform to ground level. Each support leg 44 is pivotally attached to the underside of the floor 22 so that they may be rotated from a vertical support position, as shown in FIG. 1, to a horizontal travel position as shown in FIG. 2.

[0042] In FIG. 4 a floor receiver means 54 attached to the underside of the floor is illustrated. In the illustrated embodiment of FIG. 4 the floor receiver means is an open saddle 54 that is adapted to straddle bar 55. The floor receiver means in the preferred embodiment bisects the floor extending straight across the width of the floor from a forward side edge, adjacent the vehicle, to the opposite rear side edge. However, it should be appreciated that the floor receiver means may not necessarily extend across the entire width of the camper floor. The bar 55 has two sets of juxtaposed drilled through holes 58, one set adjacent each end of the coupler bar 55. A hitch receiver 56 is fixed onto the undercarriage of the vehicle in the present invention. The bar 55 is inserted into the hitch receiver 56 and the camper is straddled over the coupler bar 55. The coupler bar is fastened to the hitch receiver at one end by an insertion pin that is passed through aligned openings 58 and 59 and the camper is fastened onto the bar at its other end by a pin inserted through aligned holes 57 and 58. Whereby the camper is now securely coupled onto the vehicle so that a person may embark on a camping hip.

[0043] As seen in FIG. 2, the all the rear lights on the pickup truck are legally visible. It is contemplated that in the alternative that well-known adaptor means, including but not limited to size, shape and/or raise/drop adaptors may be first connected to the hitch receiver and the coupler bar 55 is then coupled to the adaptor means. A raise/drop adaptor may be selected and employed so that the collapsed camper does not illegally obstruct the rear lights of a vehicle, including but not limited to tail lights, parking lights, turn signals, backup lights and braking lights. See U.S. Pat. No. 4,280,713 (Bruhn) which is incorporated herein by reference in its entirety. Other well-known methods for raising or lowering the vehicle hitching position as needed may also be employed, see both U.S. Pat. No. 5,649,656 (Davy) and U.S. Pat. No. 5,950,890 (Darby) which are both incorporated herein by reference in their entirety. However, a hitch “drop” adaptor may not be desirable as it would unduly impede on ground clearance or the vehicle aerodynamics during travel. Alternatively, if it is impractical or undesirable to raise or lower the camper as needed for legally visible rear lights, it is contemplated that in a preferred embodiment that the rear lights of a vehicle, including but not limited to tail lights, parking lights, turn signals, backup lights and braking lights could be integrated into the design of the small camper. For instance, lights could be positioned on the collapsed camper side facing traffic behind the pick-up truck, see FIG. 2, as it moves on down the highway. Such integrated camper lights can be connected to the vehicle electrical control system using a well-known adaptor as are commonly employed on trailers towed behind small private vehicles.

[0044] It is contemplated that the floor receiver means may alternatively be a hollow structural section instead of an open saddle as well-known in the art, see U.S. Pat. No. 8,505,932 (Piccirillo) which is herein incorporated by reference in its entirety.

[0045] The coupler support bar 55 holds the camper in a horizontal plane so that it will be substantially parallel to the road surface during travel. The floor 22 is fixed in this horizontal plane above the hitch receiver so as to provide for adequate ground clearance during travel. The support legs 44 in their retracted travel position, as shown in FIG. 2, are located adjacent the underside of the floor 22. As illustrated in FIGS. 2 and 4, with the camper in the travel position, the foot 45 of each support leg is located above the bottom edges of the saddle means 54. The bottom edges of the saddle 54 as shown in FIGS. 1 and 2 do not extend beyond the bottom surface of the support bar 55 or below the hitch receiver 56. The entire camper is located completely above the bottom of the hitch receiver. Consequently, the ground clearance of the attached camper does not compromise the original ground clearance of the vehicle.

[0046] FIG. 5 discloses a second preferred embodiment of the invention. FIG. 5 mostly discloses common elements with the first embodiment disclosed in FIGS. 1-4. The FIG. 5 embodiment employs the same reference numbers for identifying those common elements. Upon inspection of FIG. 5 it should be appreciated that the second camper embodiment is identical to the first embodiment but for a pair of rotating wheels 61 fixed at one end of the floor 22 (only one is shown in FIG. 5, the other wheel is hidden on the opposite side of camper).

[0047] The camper in its fully collapsed position may be removed from the coupler bar after removing an insertion pin. The camper may be next set on the ground where an operator may then grasp the opposite end of the camper and lift it onto the wheels 61 and maneuver the camper to a desired location. A person can either pull the fully collapsed camper or push it along while it rests on wheels 61 much like a wheel barrow is transported.

[0048] While certain novel features of this invention have been shown and described, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the illustrated invention and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
