Detachable goose-neck towing device

Claim 2

A towing device comprising: an elongated body having front and rear portions, said front portion being adapted to be connected to a towing vehicle, and means for detachably connecting said rear portion to a trailer frame, said means having a pocket including a recess and a surface facing the recess, and the rear portion including a projection receivable in said pocket between the recess and surface, said surface cooperating with said rear Portion for holding the projection in the pocket; and stabilizing means connectable between the body and the trailer frame serving to maintain the rear portion in cooperative relation with said surface.

Claim 3

The towing device of claim 1, wherein said surface faces downwardly and said rear portion has a member from which the projection depends, and said pocket has a mouth which opens forwardly, said projection being receivable in the pocket by insertion into said mouth with the member inclined rearwardly and thereafter swinging the member upwardly against said surface for holding the projection in the pocket.

Claim 4

The towing device of claim 1, wherein said body includes a pair of rearwardly diverging members terminating in parallel end portions, each end portion having a projection thereon, and said trailer frame has fixed thereto an upstanding structure having a pair of pockets, in which said projections are receivable, said rearwardly diverging members being interconnected by a transverse member disposed forwardly of said projections, and said stabilizing means includes a rigid bar connected to said transverse member, the lower end of said bar being connected to the trailer frame, said bar being inclined forwardly transversely of said structure, whereby movement imparted to the rearwardly diverging members is transmitted to the trailer frame.

Claim 5

A towing device comprising an elongated body having front and rear portions, said front portion being adapted to be connected to a towing vehicle, and means for detachably locking said rear portion to a trailer frame including a projection which depends from said rear portion, and said trailer frame having a structure with a pocket for receiving the projection, said structure having a surface cooperating with said rear portion for holding the projection in the pocket, said pocket having a recess in facing relation to said surface, said projection being insertable between the surface and the recess and having a part fitting into the latter; and stabilizing means connectable between the body and trailer frame, said stabilizing means serving to transmit towing force and to maintain said rear portion in cooperative relation with said surface for holding the body locked to the trailer frame.

Claim 6

A towing device comprising an elongated body having front and rear portions, said front portion being adapted to be connected to a towing vehicle, and means for detachably locking said rear portion to a trailer frame including a projection which depends from said rear portion, and said trailer frame having a structure with a pocket for receiving the projection, said structure having a surface cooperating with said rear portion for holding the projection in the pocket, said pocket having a recess in facing relation to said surface, said projection being insertable between the surface and the recess and having a part fitting into the latter; and stabilizing means connectable between the body and trailer frame, said stabilizing means serving to transmit towing force and to maintain said rear portion in cooperative relation with said surface for holding the body locked to the trailer frame.

Claim 7

The towing device of claim 4, wherein said recess is elongated along a direction transverse to the direction of towing, and said surface is inclined and faces the direction of towing.

Claim 8

The towing device of claim 5, wherein said recess is a semi-cylindrical concavity, and said part has a mating convexity.

Claim 9

A towing device comprising an elongated body having front and rear portions, said front portion being adapted to be connected to a towing vehicle and means for detachably locking said rear portion to a trailer frame, said body including a pair of rearwardly diverging members, said front portion depending from the forward ends of said members and terminating in a pivotal connector, said rear portion including a pair of depending projections on the rear ends of said members, said projections being receivable in a pair of pockets on the trailer frame, each of said pockets having a mouth opening forwardly and a concavity, said projections being inserted into the mouths of the pockets while the members are inclined rearwardly, after which the members are swung into substantially horizontal position for seating the projections in the concavities, the tops of said mouths of the pockets being defined by plates which are inclined forwardly, in facing relation to the concavities, and have undersurfaces engageable with sloping surfaces on the projections for retaining them seated in the concavities when the members are swung upwardly to substantially horizontal position; and stabilizing means connectable between the body and the trailer frame, said stabilizing means serving to transmit towing force and to maintain the body locked to the trailer frame.

Claim 10

A towing device comprising an elongated body having front and rear portions, said front portion being adapted to be connected to a towing vehicle and means for detachably locking said rear portion to a trailer frame, said body including a pair of rearwardly diverging members, said front portion depending from the forward ends of said members and terminating in a pivotal connector, said rear portion including a pair of depending projections on the rear ends of said members, said projections being receivable in a pair of pockets on the trailer frame, each of said pockets having a mouth opening forwardly and a concavity, said projections being inserted into the mouths of the pockets while the members are inclined rearwardly, after which the members are swung into substantially horizontal position for seating the projections in the concavities, the tops of said mouths of the pockets being defined by plates which are inclined forwardly, in facing relation to the concavities, and have undersurfaces engageable with sloping surfaces on the projections for retaining them seated in the concavities when the members are swung upwardly to substantially horizontal position; and stabilizing means connectable between the body and the trailer frame, said stabilizing means serving to transmit towing force and to maintain the body locked to the trailer frame.
