Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
189 words
A camper trailer having a wheel-mounted rigid box, a rigid top for closing said box and for serving as a roof for said camper trailer when raised above said box, the improvement therewith comprising: pairs of toggle levers, each at one corner of said box and formed of two hingedly interconnected levers of which the other ends are pivotally connected to said top and to said box, respectively, in a manner such that the levers are displaceable in planes extending in the direction of travel of said trailer; manually slidable drawers at each end of said box and carried thereby for guided horizontal translation movement between a retracted stowaway position within said box and an extended useful position protruding from said box; link means interconnecting said drawers and said pairs of toggle levers so that movement of said drawers cause actuation of said levers and displacement of said top relative to said box and operating means interconnecting said two drawers for simultaneous movement thereof between said positions upon one only of said drawers being moved whereby said top may be raised above said box while being kept substantially horizontal.
Claim 2
Dependent Claim
189 words
A camper trailer having a wheel-mounted rigid box, a rigid top for closing said box and for serving as a roof for said camper trailer when raised above said box, the improvement therewith comprising: pairs of toggle levers, each at one corner of said box and formed of two hingedly interconnected levers of which the other ends are pivotally connected to said top and to said box, respectively, in a manner such that the levers are displaceable in planes extending in the direction of travel of said trailer; manually slidable drawers at each end of said box and carried thereby for guided horizontal translation movement between a retracted stowaway position within said box and an extended useful position protruding from said box; link means interconnecting said drawers and said pairs of toggle levers so that movement of said drawers cause actuation of said levers and displacement of said top relative to said box and operating means interconnecting said two drawers for simultaneous movement thereof between said positions upon one only of said drawers being moved whereby said top may be raised above said box while being kept substantially horizontal.
Claim 3
Dependent Claim
86 words
A camper trailer as claimed in claim 1, wherein said box is four sided and further including pivotally interconnected rigid wall sections hinged to said top and to two sides of said box so as to be foldable within said box in closed position thereof and extendable in the raised position of said top, and further including side panels hinged to the sides of said drawer and openable to upstand from said drawer and to engage said wall sections to lock said drawer in extended position.
Claim 4
Dependent Claim
48 words
A camper trailer as claimed in claim 2, further including pivotally interconnected drawer enclosing rigid end wall and roof sections hinged to said top and pivotable between a stowaway folded position under said top and a useful position forming a roof and an end wall for said drawer.
Claim 5
Dependent Claim
79 words
A camper trailer as claimed in claim 1, wherein said drawer operating means comprises pulleys mounted for rotation inside said box and including outer pulleys located outwardly with respect to the inner ends of said drawers and inner pulleys; cables each connected to the inner end of one drawer, successively winding around outer and inner pulleys and connected at the other end thereof to the other drawer, whereby pulling on one drawer causes automatic withdrawal of the other drawer.
Claim 6
Dependent Claim
96 words
A camper trailer as claimed in claim 2, further including a door for said caMper trailer located on one side of said box, said door consisting of a bottom door panel and of as many additional door panels as there are rigid wall sections on said last named side of said box, said bottom door panel laterally hinged in a door opening in said side of said box and said additional door panels laterally hinged in door openings in said rigid wall sections, and latch means releasably to latch said door panels together in coplanar condition.
Claim 7
Dependent Claim
50 words
A camper trailer as claimed in claim 1, wherein said box is of rectangular shape and has a floor and end walls, said drawer mounted for movement longitudinally of said box in a plane substantially parallel to said floor just above the top edge of one of said end walls.
Claim 8
Dependent Claim
66 words
A camper trailer as claimed in claim 1, wherein said box is of rectangular shape and has a floor and end walls there being two drawers each located at one of said box and further including operating means interconnecting said two drawers for simultaneous movement of said two drawers between extended and retracted positions respectively upon an operating force exerted on only one of said drawers.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
43 words
A camper trailer as claimed in claim 1, further including coil spring means surrounding the hinge interconnection of said toggle levers and having ends engaging said toggle levers so as to be stressed when said toggle levers are folded about their hinge interconnection.
Claim 11
Dependent Claim
71 words
A camper trailer as claimed in claim 1, wherein said link means consist of rigid bars pivotally connected at one end to said drawers and having a lost motion pivotal connection with the pivotal interconnection of said toggle levers to permit a greater movement of said drawer between retracted and extended position than permissible with the movement of only said hinge interconnection between folded and straightened positions of said toggle levers.
Claim 12
Dependent Claim
89 words
A camper trailer as claimed in claim 10, wherein said box is four sided and has a floor, there being two drawers located at two opposite sides of said box, each mounted for guided translation movement in a plane substantially parallel to said floor just above the top edge of an associated box side, the pivoting attachment of said rigid bars to said drawers being disposed, in the closed position of said top, between the pivotal connections of the respective toggle levers to said box and to said top.
