SHEET 5 [IF 5 HTTOR/VEY HARD PANEL FOLDOUT BUNK SHELTER Camper trailers, of the expandable type having canvas or tarpaulin foldout bunk shelters, or the like, are quite uncomfortable to live and sleep in because the canvas or tarps of such foldout shelters become damp and clammy in rainy weather, are often too hot or too cold as they fluctuate with changes of outside temperatures, due to poor insulative properties, and present very little safeguard security. I-Iuntsmen, fishermen and vacationers have all experienced the hinterland insecurity, and the discomfort of living under wet, cold or hot canvas for days at a time.

The purpose of this invention is to lessen the above disadvantages and provide a foldout bunk shelter that is impervious to rain, provides a relatively high degree of temperature insulation, and offers reasonable protective security, thereby resulting in a foldout bunk shelter of greatly increased living comfort and suitable for habitation over vacation and hunting periods, whatever the weather.

An object of this invention is the provision of a foldout bunk, for a camper trailer, distinguished by stable, hard, or rigid sidewall and roof panels having good water-impervious and temperature insulation properties suitable for the intended purpose.

Another object is to provide a foldout bunk, for a camper trailer, that is pivotally movable from a position within to a position without the trailer.

Yet another object is to provide a foldout bunk, for a camper trailer, that is supported for slidable movement from a position within to a position without the trailer, and wherein such support means terminates outwardly in cantilever support means.

Still another object is the provision of a foldout bunk having a pitched roof mounted on hard foldable sidewalls, said sidewalls being foldable along their median lines.

Other specific features and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings in which like reference numerals designate like parts throughout the figures thereof and wherein:

Referring now to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views, there is shown in FIG. 8 a somewhat conventional collapsible or foldable vehicular camper trailer to which the present invention is applicable.

However, the invention is not limited to collapsible-type trailers, but is also adaptable to permanently erected wall trailers.

The vehicular trailer proper comprises a traylike body generally indicated at 20 supported on a wheeled chassis frame generally indicated at 21 and is provided with conventional bar hitch means such as generally indicated at 22 shown in FIG. 2. An open-ended shell structure, comprising a roof and sidewalls, provide a shelter or covering on the trailer as hereinafter described.

The traylike body 20 comprises a rectangular flat open-top box or base having a bottom 23, two

sidewalls

24 and 25, and two

end walls

26 and 27.

Inwardly foldable sidewall means generally indicated at 28 and 29, see FIGS. 8 and 12, pivotally interconnect the

box sidewalls

24 and 25 with the downwardly extending side flanges 30 of the roof generally indicated at 31 by means of longitudinally extending hinges such as at 32 and 33, respectively, thereby providing a shell or shelter structure over the trailer box.

The foldable sidewall assembly 28 comprises a lower section 34 which is pivotally connected to an upper section 35 by means of a longitudinally extending hinge 36. Sidewall 28 in cludes a foldable door 28'.

The foldable sidewall assembly 29 comprises a lower section 37 which is pivotally connected to an upper section 38 by means of a longitudinally extending hinge 39.

Conventional elevating means for raising said roof and foldable sidewalls from a collapsed position to an erected position, see FIG. 8, comprise post support means generally indicated at 41, a cable system generally indicated at 42 connected to said roof and with said post support means, and rotary crank means 43 journaled in said body box and operatively connected with said cable system, whereby as said crank means is actuated in one direction the roof is raised; and as said crank is actuated in the opposite direction the roof is lowered.

The post support means comprises four hollow posts mounted at each comer of the trailer box, respectively, such as post 44, which is pin connected to the trailer box by means of pin 45 and held erected by means of friction clip 46. Said posts are pivotally movable downwardly to a horizontal position and held by a bracket such as at 47 mounted on said box, in a collapsed position, when the camper trailer as a whole is collapsed for travel from place to place.

A pin or pulley 48 is mounted in the upper end of post 44, and a companion pin or corner pulley 49 is mounted on the trailer box beneath the lower end of said post 44.

An endless cable 51 has one end wound around the crank means 43, as at 52, and the other end threaded through hollow post 44 and looped around pulley 48 at the upper end of aid post 44. Intermediately, the endless cable passes over corner pulley 49.

An arm 53, secured to one run of the cable in said post, extends through a longitudinal slot 54 in said post, and engages a projecting bracket 55 mounted on said roof at the corner thereof. Said arm functions to carry said roof in up and down movement, as said crank is correspondingly actuated.

Similar elevating mechanism is provided at each other corner of the trailer box and roof, each operatively connected to said crank means, for raising the roof uniformly and level.

It is to be noted that the shelter shell of the basic camper trailer of FIG. 8 is shown without end closures. Said end closures of bunk openings of said shell are provided with extendable foldout bunk shelters to increase the living area beyond the box body 20 area, as hereinafter described and shown in FIGS. 1 through 6, 9, 10, 11 and 12.

In view of the fact that the foldout bunk structures at the front and rear ends of the trailer are identical, the following description of the bunk structure at the front end of the trailer will suffice for both bunk structures.

A rectangular movable platform or floor 56, such as shown in FIG. 7, is provided in the trailer having up-turned flanges around the edges thereof, such as

side flanges

57 and 58, and inner and outer flanges 59 and 61, respectively. Said movable floor 56 is disposed horizontally and inverted, and spaced above the box or trailer floor 23 and at the front end opening of the shell, for an initial position, as indicated by dotted lines 56, and pivotally hinged to the front wall of the trailer box as by hinge 60, see FIG. 7; or said floor may be disposed horizontally and upright as indicated by dotted lines 56", see FIG. 11, and be slidably supported on the trailer by guideway and slidable rail means, see FIGS. 9 and 10.

Said slidably supported movable floor is provided with a pair of longitudinally disposed

guide rails

62 and 63 mounted on the

floor side flanges

57 and 58, respectively, by any means, such as screws 64, see FIGS. 9, 10, 12 and 13.

Said guide rails are slidably supported in longitudinally disposed guideways or

channel iron members

65 and 66 mounted on

box sides

24 and 25, respectively, by any means, such as screws 67, see FIG. 13.

Said guide rails extend rearwardly of the movable floor 56, see FIGS. 9 and 10, to provide cantilever support in the guideways when the movable floor is slidably disposed outwardly of said front end or bunk opening with the inner floor edge 59 disposed externally of and adjacent the lower edge portion of said bunk opening, for a final position. At its outer final position the floor is cantilever supported on the rails extended from their guideways.

The side, end, and roof panels hereinafter to be described are of stable material characterized by being hard, strong, and impervious to water, such as of wood, metal, or fiber glass material, foam core material, hollow construction, or the like, suitable for intended purpose.

A pair of such similarly configured

stable side panels

68 and 69, oppositely disposed, are hingedly connected at their lower edge portions to the edges of said

side floor flanges

57 and 58, respectively, by means of longitudinal hinges 71 and 72, see FIGS. 9, l and 12, said stable side panels being movable from a collapsed position overlaying said floor 56 to a vertical erected position.

A stable end panel 73 is hingedly connected, at its lower edge portion, to the edge of the outer floor flange 61, by means of longitudinal hinge 74, said hard end panel being movable from a collapsed position overlaying the floor 56 to a vertical erected position.

It is understood that the

floor flanges

57, 58 and 61 vary slightly in height to accommodate and allow said side and end panels to fold over each other in a nested arrangement overlaying the floor.

Also, it is understood, that the stable side and end panels are of a size dimension to fall and collapse within the confines of the floor flanges.

Under normal conditions, a cushion mattress, or the like, not shown, on the bunk floor 56, may support the collapsed side and end panels in a substantially horizontal position; otherwise said panels may be supported directly on said floor.

A stable roof panel 75, dimensioned to suitably cover the zone defined by said erected stable side and end panels, is hingedly connected to said roof at the adjacent downwardly extended roof flange 30, by means of longitudinal hinge 76, see FIG. 7, operative to swing from an initial position under and adjacent the trailer roof 31 as indicated by dotted lines 77, through the end opening, and to a final position to overlay the upper edges of said erected side and end panels as indicated by arrow 78. Any suitable releaseable means can be provided for securing said roof panel in its initial position at the underside of the trailer roof 31, such as rotatable latch bar means generally indicated at 79, see FIG. 7. Also any suitable releaseable means can be provided for securing said roof panel in its final position to the erected end panel, such as slidable latch means generally indicated at 81, see FIGS. 9 and 10, said latch means being associated with latch receiving recesses in said end panel as indicated at 82, see FIG. 10.

Said roof panel means includes downwardly extending

flanges

83, 84 and 85 along the two side edges and end edge thereof respectively, see FIG. 9 and 7.

A pair of

elongated cleats

86 and 87 are mounted on the underside of roof panel 75, spaced inwardly from and disposed along the side edge flanges thereof, respectively, see FIG. 9. The slots or channels formed between said cleats and said roof side flanges are adapted to receive therein the upper edge portions of

side panels

68 and 69, respectively, for releaseable securement therein when said panels are functionally erected.

The vertical end edges of the

side panels

68 and 69, erected, are also provided with inwardly extending

flanges

88 and 89, respectively, see FIGS. 9 and 10, to provide abutment stop means for end panel 73, when said end panel is disposed erected and cooperatively secured by the latch means 81. Roof end flange 85 also functions as abutment stop means for end panel 73.

Operation: When one desires to erect the trailer from its collapsed and compact position as shown in FIG. 1, one initially turns the rotary crank means 43, see FIG. 8, to start the raising of the trailer roof 31 and the associated

side panels

28 and 29, such as shown in FIGS. 2 and 8.

Continued turning of the crank 43 eventually raises the trailer roof and associated sides to the fully erected position shown in FIG. 3.

In the event one is dealing with the slidable bunk floor construction, one then grasps the floor means 56 and pulls said floor means and associated stable side and end panels thereon from a dotted position 56" in the trailer to a position outwardly of the trailer, as indicated by arrow 90, the floor means being slidably movable and supported on

guide rails

62 and 63 slidably mounted in

guideways

65 and 66, see FIGS. 4, 11 and 9.

To erect the foldout bunk shell, one merely turns the rotatable latch 79, see FIGS. 7 and 4, to release the stable roof panel 75 from its stored roof position, as shown by dotted lines 77, through the end opening of the trailer, and to an elevated position as shown by arrow 78, and holds same elevated while erecting the side panels as follows.

To erect the stable side panels of the foldout bunk shelter, one merely pivotally raises stable side panel 68 to a vertical position as shown in FIGS. 5, 7 and 9, engaging the top end portion of said side panel in the slot or channel formed between cleat 86 and roof flange 83.

To erect the other side panel, one pivotally raises such hard panel 69 to a vertical position as shown in FIGS. 6 and 9, engaging the top end portion of said side panel in the slot or channel formed between cleat 87 and roof flange 84.

Finally, the end stable panel 73 is pivotally raised, from within the trailer, to a vertical position abutting with side panel and

roof flanges

88, 89 and 85, respectively, and finally engaged in said erected position by means of slidable latch means 81, see FIGS. 6 and 10.

The corresponding foldout shelter means on the other end of the trailer is similarly unfolded, raised, and erected; and both foldout shelters are thus ready for occupation.

To fold, collapse, and store said foldout bunk shelters back into the trailer, one merely reverses the aforesaid erection operation.

One may provide a removable brace means 92 as shown in FIG. 11, to provide greater stability and security to the pulled out floor means.

In the event one is dealing with the pivotally hinged bunk floor construction, see FIGS. 3 and 7, wherein the floor is pivotally hinged as at 60, and supported on cleats 60 mounted on the trailer box sides 24 and 25, by any means, one reaches into the trailer and grasps the free inner edge of the floor and movably pivots the floor upwardly and outwardly, from its initial dotted line position 56 within the trailer to a final position outwardly of the trailer as indicated by arrow 102. A removable brace means 101 interconnecting the floor 56 and the trailer wall 27 is provided to hold the floor in a stabilized horizontal position.

In erecting this pivotal construction, the roof panel 75 is likewise first released from its stored position 77, swung outwardly, and manually held elevated while the side panels are being erected.

To provide pitch for the roof panel, it is preferred that said hard side panels have upper edges that decline from a high point at their inner ends adjacent said trailer to a relatively low point at their outer ends adjacent said stable end panel.

The modification shown in FIG. 14 illustrates a bunk shelter having stable foldable side panels generally indicated at 93 and 94, foldable at their geometrical median lines by means of

hinges

95 and 96.

Said foldable side panels, pivotally interconnect the movable floor 56 with the roof 75 by means of longitudinally extending hinges such as indicated at 97 and 98, respectively, in lieu of the roof being hingedly attached to the trailer roof as hereinbefore described. Thus, in this modified construction, the bunk shelter roof rides up and down with the attached foldable side panels.

The end panel 99 is hingedly mounted on the floor and is pivotally erectable to an upright position and secured as is end panel 73 hereinbefore described.

In this modification, the roof and connected foldable side panels are raised manually, and the end panel then erected and secured to hold the bunk shelter, erected and assembled, as hereinbefore provided.

This modification can have the floor thereof slidably supported on guideway and slidable rail means, or pivotally hinged, as hereinbefore described.

Some characteristic features of this invention are the provision of a foldout bunk shelter made of stable and impervious panels; the provision of a foldout bunk shelter having a pitched roof and foldable stable sidewalls foldable along median lines thereof; the provision of a foldout bunk shelter movable pivotally from a position within to a position without the trailer; and the provision of a foldout bunk shelter slidably supported for movement outwardly of the trailer, and wherein such support means terminates outwardly in cantilever support means.

Ovbiously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood, that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
