B60p 3/34; B62b 19/00 U.S. Cl. 29623 13 Claims ABSTRACT OF THE DISCLOSURE A vehicle, preferably on ski-runners, comprising a body having upstanding side and end walls surrounding a floor, with a hinged leaf at each side of the body, said leaves being respectively swingable about separate longitudinal axes, between in-folded and laterally extended, substantially horizontal positions, removable brace means for supporting said leaves in their extended positions, a hip-type tent having the lower edges of its side panels secured to the free edges of said leaves, respectively, two major U-shaped frames removably associated with the vehicle for supporting the apex of the tent and two minor U-shaped frames removably associated with the vehicle for supporting the respective hips of the tent to retain the tent in extended, use condition; all four frames being collapsible for storage in the body of the vehicle and the tent being foldable about the leaves, when collapsed, and when the leaves are in-turned, to establish a travel condition, a removable tarpaulin preferably being provided for securement to the vehicle to overlie and protect the folded tent. In the preferred form, the runners are provided with readily-removable wear bars and improved support means mounts the vehicle body on the runners and a draft tongue is connected in a novel manner to the runners.

BACKGROUND OF THE INVENTION Field of the invention The present invention relates to camper trailers, preferably for use behind a snowmobile, and more particularly to the provision of an improved form of trailer specially adapted for carrying a novel hip-type tent, collapsible supporting frame elements therefor and novel means for readily operatively associating the support frames with the tent and dismantling and storing the tent structure for travel.

Description of the prior art The present invention is an improvement over prior art campers primarily in the leaf structure and arrangement, the disclosed brace means for the leaves when extended, and the novel frame structure and arrangement, as well as the manner of association of the tent with the leaves whereby erection, collapse and storage of the tent structure are facilitated.

SUMMARY OF THE INVENTION The present invention relates to novel trailer body structure, novel tent and support means therefor, a novel association of the tent structure with the vehicle structure, novel runner structure and means for supporting the vehicle thereon and novel draft structure for the vehicle. Thus, the primary object of the present invention is to provide an improved camper trailer, particularly adapted for use in snow and to be drawn by a snowmobile, the structure being compact both vertically and transversely when arranged for travel and yet being quite commodious and comfortable when opened and with the tent structure erected for stationary camping.

Further objects of the invention will appear as the description proceeds.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring, now, particularly to FIGS. 1 to 6, it will be seen that I have illustrated an elongated body indicated generally by the reference numeral 20 and formed to provide a floor 21, side walls 22 and 23, a front wall 24- and a rear wall 25 which is preferably provided with a hinged door 26, the body being supported, in a manner to be described hereinafter, from a pair of longitudinally-extended, laterally-spaced, wide ski-runners 27. Each of said runners is formed with a forward up-turned toe 28 and a rearward up-turned toe 29. Since the two runners are preferably of identical construction, only one will be described in detail.

Each runner is provided with a plurality of pairs of upstanding brackets 30 arranged in a longitudinallyspaced series medially of the runner, each such bracket pair being provided, near the top thereof, with aligned perforations 31. Depending from the body 20 adjacent each lateral side thereof is a plurality of pairs of laterally spaced supports 32 disposed in a longitudinally-spaced series so arranged that the lower ends of each support pair will straddle a corresponding bracket pair on a runner. The support pairs are provided, near their lower ends, with aligned perforations for registry with the perforations 31 whereby each such support pair may be joined to, and supported from, its corresponding bracket pair by means of a bearing pin 33 penetrating the aligned perforations. The pins 33 may be secured in place in any well-known fashion.

An upstanding fillet plate 34 is arranged at each end of the runner in such a fashion as to brace and strengthen the up-turned toe; and at least the plates 34 at the forward ends of the runners will be provided, near their upper ends, with perforations 35. It will be clear that the perforations 35 on the two runners will be coaxial.

For each forward fillet plate 34 I provide a bell-crank lever 36 having a horizontal arm 37, perforated near its rear end to receive a pivot pin 38 received in the perforation 35 of the corresponding plate, the levers 36 preferably being disposed at the inner sides of the respective plates 34. Each such lever 36 further comprises a substantially vertical arm 39 provided with a perforation 40 at its upper end. A draft tongue, indicated generally by the reference numeral 41, is provided at its forward end with a link 42 pivoted about a horizontal axis and adapted to be connected to a hitch element carried by a draft vehicle such as, for instance, a snowmobile (not shown). At its rear end, the tongue 41 is formed to provide diverging forks 43 each of which is perforated near its rear end to receive a pivot pin (not shown) supported in the perforation 40 of one of the levers 36. This arrangement facilitates movement of the trailer, behind a draft vehicle, over relatively rough ground, in that it permits relatively free movement of the tongue 41, relative to the towed vehicle, in a vertical plane.

It will be seen that the runners 27, as illustrated, are quite broad to provide maximum area for supporting the trailer as it is drawn over snow; and I presently believe that it will be desirable to form the runners from aluminum or an aluminum alloy. Preferably, the spacing between the runners will be substantially equal to the spacing between the treads of a conventional snowmobile, so that the runners will follow closely in the packed-snow paths of the treads of the towing vehicle. In order to protect the relatively soft metal of the runner bodies against damage from logs, stones and other hard objects which may be encountered in transit, I prefer to thicken the medial region of the bottom surface of each runner and to form a longitudinal groove or channel 44 in such thickened portion, such channel extending substantially from end-to-end of the runner, and to mount a wear bar 45 in such channel in such a relationship that the wear body protrudes beyond the bottom surface of the thickened portion. As shown, and preferably, the channel will be substantially semi-cylindrical in form and the wear bar will be a steel rod of circular cross section and having a radius substantially equal to that of the channel, so that approximately one-half of the body of the rod 45' will protrude beyond the lowermost surface of the runner.

Preferably, each toe of the runner will be formed, near its distal extremity, with a perforation 46 therethrough adapted to receive and pass a turned-up end of the bar 45, the extremity 47 of said turned-up end being threaded and protruding beyond the upper surface of the runner toe for the reception of a cap nut 48 which can be turned down into bearing relation with the upper surface of the runner toe thus securely, but releasably, fastening the wear bar 45 to the runner. It will be obvious that, because of this detail of construction, a worn or damaged wear bar 45 may be readily removed and replaced simply by removing the two cap nuts 48, extracting the turnedup ends of the rod from the perforations 46 in which they are mounted, and mounting a new bar in the same way on the runner.

Referring, now, more particularly to FIGS. 5 and 6, it will be seen that I prefer to provide side boards 49 and 50 secured, respectively, to the side walls 23 and 22 of the body 20 and secured, as Well, to the front and rear end walls 24 and 25, each such side board extending a short distance inwardly over the open mouth of the body 20. A first leaf 51 is arranged to span the walls 24 and 25 and is hinged to the inner edge of the side board 49 to swing about an axis parallel to the side wall 23. Hinge means 53, which may preferably be of the piano hinge type, so supports the leaf 51 to swing between the extended position illustrated in FIG. 5 and the in-folded position illustrated in solid lines in FIG. 6, the width of the leaf 51 being just small enough so that its free edge will clear the inner edge of the side board 50. A second leaf 52, similar in all respects to the leaf 51, is similarly hinged at 54 to the inner edge of the side board 50.

For supporting the free edge of the leaf 51 in its infolded position, I provide one or more arms 56, each pivoted at its lower end, as at 57, to one of a plurality of braces 55 secured to the wall 22 and supporting the side board 50. When the leaves 51 and 52 are extended, the arms 56 will be disposed in vertical positions within the boundaries of their associated braces 55, as shown in FIG. 5. If desired, any conventional form of retaining means may be provided for holding the arms 56 in such vertical positions. When, however, the leaf 51 is to be moved to its solid line position of FIG. 6, the upper ends of the arms 56 will be swung away from the wall 22 to a limiting position, as shown in FIG. 6, which position may be determined by a chain 58 or other equivalent flexible strand means anchored at one end to the brace 55 and at its other end to the upper portion of the arm 56. As is clearly illustrated in FIG. 6, the arms 56, in their in-swung positions, will underlie the free edge of the leaf 51 when it is in its in-folded position, to support the same.

Brace means is provided for effectively retaining the leaves 51 and 52 in their extended positions. At spaced points along each side wall 22 and 23, I mount hasps 59, the configuration of which is illustrated in 'FIG. 6A. Each such hasp thus provides an upwardly-opening socket 60. At correspondingly spaced points along the outer surface of each leaf and adjacent the free edge thereof, I mount similar hasps which provide sockets opening inwardly when the leaves are in extended positions. Strut members 61, which may comprise tubular sections, are provided at their opposite ends with flattened tab extensions 62 proportioned and designed to be received with a slip fit in such sockets. Such tab extensions are turned, from a. common side of the strut, at angles of substantially 45. Thus, one tab extension of each strut may be entered in the socket 60 of a hasp 59 on a side wall of the body, While the opposite tab extension of the same strut may be entered in the socket provided by the correspondinglylocated hasp on one of the leaves, thereby providing a support against downward movement of the free edge of that leaf. Several such struts will be arranged along each side of the assembly to provide adequate support for each leaf.

The brace means for the leaves in their extended position includes, as well, hold-down means to restrain the free edges of the leaves against upward movement. As shown, connector means suggested at 63 in FIG. 5 will be arranged at suitably spaced points along each side wall and at corresponding points along the outer surface of each leaf near the free edge thereof; and suitable resiliently extensible means, as suggested at 64, will be connected between each pair of such connector means. Each such resiliently extensible means 64 may assume any one of several known forms such as, for instance, a continuous, rubberoid strap with a medial metal guard sheath; or a metal strip with coiled springs arranged to extend beyond one or both ends thereof.

As an element of the camper, I prefer to provide a hip type tent, indicated generally by the reference numeral 65 and comprising roof panels 66 and 67 meeting to define the apex of the tent, side panels 68 and 69, a front panel 70 and a rear panel 71, all joined in the conventiona1 fashion and the rear panel preferably being provided with a slide fastener 72 substantially registering with the distal edge of the door 26. As is perhaps most clearly illustrated in FIGS. 12 and 13, the lower edge region 132 of the side panel 69 is turned under the free edge of the leaf 51 and secured thereto by any suitable fastening means which, in the present drawings, is shown as nails or screws 133 providing a semi-permanent securement. Similarly, the lower edge region 134 of the side panel 68 is turned under the free edge of the lead 52 and is secured thereto by suitable means indicated at 135. If desired, the lower edge regions of the front and rear panels 70 and 71 may be secured to the ends of the leaves 51 and 52, but preferably by readily-separable fastening means (not shown).

A first major U-shaped frame is indicated generally by the reference numeral 73 and, in the preferred form of my invention (comprises a base 74 and two legs 75 and 76 hingedly connected, respectively, to opposite ends of the base 74. As is most clearly illustrated in FIGS. 7 and 16, each member of the frame 73 may preferably be a hollow tube. One end portion of the base member 74 is flattened, and may be curved, as indicated at 77 in FIG. 16 and said flattened portion is perforated near its distal end. Similarly, one end of the leg member 75 is flattened as at 7 8 and may be correspondingly curved and is formed with a perforation near its extremity. Thus, the leg 75 is hingedly connected to one end of the base member 74 by a pivot member 79.

Similarly, the opposite end of the base member 74 is formed with a flattened, and preferably curved, extension 80 which mates with a flattened portion 81 at one end of the leg 76, whereby the leg 76 is hinged to the base member 74 by means of a pivot 82.

As suggested in FIG. 7, the pivot members 79 and 82 may be headed bolts with each of which cooperates a securing device such as a wing nut 131; and, if desired, the cooperating faces of the flattened extensions may be serrated, in a known manner, whereby the legs may be locked aflirmatively in a multiplicity of desired relationships to the base member 74.

Because of this hinged construction, it will be apparent, the frame 73 is collapsible to a storage condition as illustrated in FIG. 16, or erectable to a tent-supporting condition as illustrated in FIG. 5. When in storage condition, the frame parts may be secured against rattling, if desired, by means of a flexible strap 83 which may be passed around the adjacent portions of the base and the two legs and secured in embracing relation thereto by any suitable fastening means such as, for instance, snap fasteners 84.

Means 89 is provided for releasably anchoring the distal end of each frame leg to an element of the vehicle; and in FIGS. 9 and I have illustrated one preferred form of such anchoring means.

Fixed to the outer surface of the rear wall 25 of the body, near the upper righthand corner thereof, is a fitting 90 comprising a base 91, an outstanding pin 92 and an enlarged head 93 carried at the distal end of said pin. A similar fitting is similarly mounted on the front wall 24 with its pin portion coaxial with the pin 92 of the fitting 90. At the distal end of each leg 75 and 76 there is pr0- vided an open-ended fork 94 proportioned and designed to straddle the pin portion of one of the fittings between the base 91 and the head 93 thereof. Thus, the frame 73 is supported upon the body 20 for oscillatory adjustment about the common axis of the pins 92.

A second major U-shaped frame indicated generally by the reference numeral 85 comprises a base 86 similar to the base 74 and legs 87 and 88. The frame 85 will be similar in construction to the frame 74 and will be similarly collapsible. As illustrated, the legs 87 and 88 are somewhat longer than the legs 75 and 76 of the frame 73, for a reason which will appear.

Anchoring means for the frame 85 may be similar to that above described, but preferably will be of the form illustrated in FIG. 11. As there illustrated, such anchoring means comprises a fitting indicated generally by the reference numeral 95 and formed to provide a base 96 which may be secured to the inner surface of the leaf 52. Such a fitting will be provided, of course, at each end of said leaf. The base 96 carries a pair of spaced, upstanding ears 97 spanned, near their upper ends, by a pivot pin 98. Each of the legs 87 and 88 is provided at its distal end with a fork 94, which may be identical with the forks on the legs 75 and 76, each such fork straddling a pin 98 and being retained between the cars 97 of its associated fitting. Thus, the frame 85 is supported from the vehicle for oscillatory adjustment about the common axis of the pins 98 of the fittings 95 at opposite ends of the leaf 52.

When the tent 65 is to be erected, the leaves 51 and 52 are extended and braced and thereupon the frames 73 and 85 are mounted upon their respective anchoring means and their bases 74 and 86 are moved into side-byside contiguous relation as suggested in FIG. 8, whereby the apex of the tent will be elevated. One or more flexible flaps 99 are associated with the interior surface of the tent adjacent its apex. As shown, one end 100 of the flap 99 is sewn to the tent material. The free end 101 of the flap 99 carries elements 102 of one or more readilysepara-ble fastening devices such as, for instance, snap fasteners, for cooperation with mating elements 103 of such fastening devices, sewn or otherwise secured to the tent surface. As shown, the first-mentioned end of the flap 99 is sewn to the roof panel 66 of the tent, while the fatsener elements 103 are secured to the opposite roof panel 67. The flap 99 is so proportioned and designed that, when it is passed beneath the frame bases 86 and 74 and its free end 101 is secured to the roof panel 67, it will act to secure the frame bases against separation and in supporting relation to the apex portion of the tent. One means of facilitating the securement of the flap end 101 in such relation is illustarted in FIG, 8 and comprises a loop or tunnel 104 secured to the roof panel 67 and so arranged that the flap end 101 may be threaded downwardly through such tunnel before bringing the elements 102 into securing relation with the elements 103.

I provide a first minor U-shaped frame 105 comprising a base 106 and legs 107 and 108, the construction of such frame being similar to that described above in connection with the frame 73. The legs of the frame 105 may be anchored to the leaf 51 in the manner described in connection with the frame 85, and said frame 105 is proportioned and designed so that its base 106 will engage the interior of the tent at the hip 109, where the side panel 69 merges with the roof panel 67. In that region, one or more flaps 110 will be provided to embrace the frame base 106 and hold the same in such cooperative relation with the tent hip.

A second minor U-shaped frame 111, comprising a base 112 and legs 113 and 114 hinged to the opposite ends of said base, is similarly anchored to the leaf 52 and is proportioned and designed to cooperate: similarly with the hip 115 of the tent, where its base will be held in such cooperative position by means of one or more flaps 116.

As suggested by broken lines in FIG. 5, mattresses 117 and 118 may be supported upon the leaves 51 and 52, respectively, said mattresses being storable in the bed of the body 26 for travel.

Thus, it will be seen that, when the tent is erected by extending the leaves 51 and 52, opening the frames 73, 85, 105 and 111, mounting said frames on their respective anchoring means and securing them to the interior of the tent in the manner above described to support the tent, comfortable and reasonably commodious living space is provided.

When the camper is to be closed for travel, the mattresses 117 and 118 will be removed from the leaves 51 and 52 and placed in the bottom of the vehicle bed. Then the frames 105 and 111 will be disconnected from their respective anchoring means, folded, secured, if desired, by straps such as the strap 83, and placed in the vehicle bed. Thereafter, the frames 73 and 85 will be removed from their anchoring means, folded, secured, and placed in the vehicle bed. Now, the apex region of the collapsed tent will be grasped and the tent material will be moved to the right, as viewed in FIG. 5, and smoothly stretched generally in the manner illustrated in FIG. 13. The arms 56 having been moved to the position of FIG. 13, the leaf 51 will now be folded inwardly, carrying with it the attached side panel 69 and the overlying portion of the roof panel 66, to fold the roof panel 66 upon itself and to move the tent parts substantially into the positions suggested in the diagrammatic illustration of FIG. 14. Now, the leaf 52, carrying the side panel 68, will be folded inwardly to overlie the leaf 51 and the tent portions overlying its outer surface, and thereupon the remaining portions of the tent will be folded over the leaf 52, as suggested in FIG. 15. Thus, the tent will be relatively smoothly and compactly arranged within the boundaries of the body 20; and a suitable tarpaulin 119, provided at its corners with fastening means 120 cooperable with fastening means 121 secured to the body corners, can be arranged to overlie the whole tent package to protect the equipment and to give it a compact, neat appearance.

In FIG. 4, I have shown details of a preferred construction of the vehicle body 20. As shown, the side wall 22 comprises an external skin 122 of aluminum sheeting internally backed by a layer of suitable thickness of insulating material such as, for instance, polystyrene foam 123; and finish paneling 124, which may be plastic sheeting, plywood or, in some instances, veneer or even heavy paper provides a finished appearance for the internal surface of the wall. Preferably, the side wall 23, the front and rear walls 24 and 25 and the door 26 may be of similar construction.

The fioor 21 will preferably comprise an external skin 125 of aluminum sheeting, a layer 126 of insulation which may be similar in character to the insulation 123, and a layer of wood flooring 127 over which there may be applied a finish layer 128 of inlaid linoleum, composition tile, or the like.

Preferably, for the protection of the body 20 against damage from relatively light collisions, I provide a perimetral molding rail 129 which may be formed of any suitable metal, extruded plastic or the like and which, as shown, is externally channeled to receive a continuous bumper strip 130, preferably of rubberoid material.

It will be seen that I have provided a snowmobile camper embodying numerous features of structural novelty cooperating to provide an assembly having significant functional advantages over previously known devices intended for a comparable purpose. While the prinicples of this invention have been discussed above in connection with a specific form of apparatus, it is to be clearly understood that this description is made by way of example and not as a limitation to the scope of the invention.
