Retractable, space-saving trailer tongue
View Patent ↗The tongue is triangular and comprises four elements, the first three elements comprise the triangle previously discussed, and the fourth element is a rectangular center pole that bisects the triangle. The first element, referred to as the base element, is permanently attached to the chassis of the trailer much as the base element of prior art tongues are also attached to the chassis of the trailer. The second and third elements comprise the legs of the triangle and they are mirror images of each other. The fourth element is the center pole. The center pole bisects the triangle and is composed of two segments. The proximal segment, being rectangular and tubular, is permanently attached to the base element. Within the proximal segment's hollow tubular part, the distal segment linearly moves inwardly and outwardly. At the far end of the center pole's distal segment is a coupler, the coupler is configured to receive the towing vehicle's trailer ball. The coupler is also configured to releasably receive first and second element's second segment as second segment may be swung towards the coupler and attached to the coupler by a pin or by a latch. As the center pole's distal segment traverses within the center pole's first part, its position may be fixed by using a pin or latch. This novelty allows the conservation of garageability without sacrificing cabin space to accomplish the maximum length. Instead, the tongue retracts to save that length in a more creative and effective manner. The information provided and listed above solely provides embodiments and does not limit the extent of this novelty.
1 . A tongue assembly used for towing a trailer, said tongue assembly having a collapsed configuration and an extended configuration, wherein said trailer comprises a chassis, and wherein said tongue assembly comprises:
three rectangular tubular frame elements forming a triangle having:
a first frame element being the base of said triangle, attached to said chassis, and having a first end and a second end;
a second frame element being a leg of said triangle further comprising
a first segment joined to said first frame element's first end,
a second segment hingedly joined at one end to said second frame element's first segment; and
a third frame element being the other leg of said triangle further comprising
a first segment joined to said first frame element's second end,
a second segment hingedly joined at one end to said third frame element's first segment; and
a center pole element being primarily rectangular and bisecting said triangle, the center pole element comprising:
a proximal segment attached to said first frame element and
a distal segment configured to be slidable within said proximal segment, comprising a coupler at its distal end configured to receive said second frame element's second segment and said third frame element's second segment;
wherein said tongue assembly is in its collapsed configuration when
said distal segment is retracted within said proximal segment;
said second frame element's second segment is folded against its first segment; and
said third frame element's second segment is folded against its first segment;
wherein said tongue assembly is in its extended configuration when
said distal segment is drawn out from said proximal segment;
said second frame element's second segment is folded against said coupler; and
said third frame element's second segment is folded against said coupler;
wherein said tongue can be retracted from its extended configuration to its collapsed configuration to reduce storage space; and
wherein said second and third frame element's second segment is releasably secured to said coupler by pins or latches when said tongue assembly is in its extended configuration.
2 . The tongue assembly of claim 1 , wherein said center pole's proximal segment further comprises a flange containing one or more openings to allow one or more rectangular tubular support elements to pass through with one end of said support element being attached to said second frame element while the opposing end of said support element being attached to said third frame element.
3 . The tongue assembly of claim 1 , further comprising a rectangular tubular structure atop of said frame elements being
the width of said first frame element,
the length of said second frame element and said third frame element first segments,
to support a platform suitable for securing cargo.
4 . The tongue assembly of claim 1 , wherein the triangle formed by said three rectangular tubular frame elements is one of an equilateral triangle and an isosceles triangle.
5 . The tongue assembly of claim 1 , wherein the tongue assembly being retractable from its extended configuration to its collapsed configuration to reduce storage space further enables said trailer to have increased interior cabin space while maintaining storability of the trailer in a garage.
6 . The tongue assembly of claim 1 , wherein the tongue assembly being retractable from its extended configuration to its collapsed configuration to reduce storage space further enables more space saving as compared to a foldable tongue, wherein said retractable tongue saves storage space more than a foldable tongue due to the thickness of the tongue.
7 . The tongue assembly of claim 1 , wherein said coupler is configured to be hitched to a towing vehicle.
8 . The tongue assembly of claim 1 , wherein said second and third frame element's second segment is releasably secured to its respective first segment by pins or latches when said tongue assembly is in its collapsed configuration.
9 . The tongue assembly of claim 1 , wherein the position of said distal segment within said proximal segment is fixed by pins or latches.
