The invention provides space saving, locking and support features for most single pole trailer tongue, having: a support leg, which has the coupler hitch on the opposite end, pivots on the tongue into a vertical position where it acts as a support for the tongue. This leg is secured vertically, using aligned brackets on both sections, by a hitch pin or locking device, so that it can be locked in place as a deterrent to theft. When in the horizontal position, the support leg is secured to the tongue by a hitch pin and may be connected to a towing vehicle. A flip-down leg, pivotally mounted on the tongue, which drops down when the securing hitch pin is removed part way, to provide temporary support for the tongue while the support leg is being moved to the vertical position.

1. A tongue for hitching a trailer to a vehicle and for supporting the trailer when it is unhitched from the vehicle, comprising: a. a first, fixed tongue member securely engageable with the trailer;b. a second, pivotable tongue member having a first, front end section, a second, rear end section, a
1. A tongue for hitching a trailer to a vehicle and for supporting the trailer when it is unhitched from the vehicle, comprising: a. a first, fixed tongue member securely engageable with the trailer;b. a second, pivotable tongue member having a first, front end section, a second, rear end section, and an intermediate section between the first end section and the second end section;c. hitching means in secure engagement with the first end section of the second tongue member to securely and temporarily hitch the second tongue member to the vehicle;d. pivot means connecting the intermediate section of the second tongue member to the first tongue member to allow pivoting of the second tongue member in relation to the first tongue member between a first position in which the second tongue member is generally aligned with the first tongue member, and a second position generally perpendicular to the first position;e. means for temporarily securing the second tongue member to the first tongue member in the first and second positions;f. a flip-down leg also mounted on said pivoting means for movement between a first position, in which it extends rearwardly beside said first tongue member, and a second, lowered position in which it extends downwardly from said pivot means and can support the trailer; andg. wherein the flip down leg is of channel form, having a first channel side portion provided with an aperture and an opposing second channel side portion being recessed, said means for temporarily securing the second tongue member to the first tongue member includes a hitch pin, and said hitch pin passes through said aperture in the flip-down leg for supporting the flip-down leg in said first position;the arrangement being such that said hitch pin is movable to a partially withdrawn position where it releases the flip-down leg while the hitch pin still secures the second tongue member to the first tongue member in said first position of the second tongue member, thus allowing said flip-down leg to move to its second, lowered position and to support the trailer while the hitch pin is fully removed and while the second tongue member is moved from its first position to its second position. 2. A tongue according to claim 1, wherein, in the second position of the second tongue member, the securing means secures the latter member in its second position in which the second, rear end thereof extends downwardly along the flip-down leg, and in which a hitch pin can secure the flip-down leg to the second end section of the second tongue member. 3. A tongue according to claim 1, wherein a ground engaging foot plate is securely attached to the flip-down leg and is engageable with the ground when the flip-down leg is secured in the second position. 4. A tongue for hitching a trailer to a vehicle and for supporting the trailer when it is unhitched from the vehicle, comprising: a. a first, fixed, tongue member securely engageable with the trailer;b. a second, pivotable, tongue member having a first, front end section, a second, rear end section, and an intermediate section between the first end section and the second end section;c. hitching means in secure engagement with the first end section of the second tongue member to securely and temporarily hitch the second tongue member to the vehicle;d. pivot means connecting the intermediate section of the second tongue member to the first tongue member to allow pivoting of the second tongue member in relation to the first tongue member between a first position in which the second tongue member is generally aligned with the first tongue member, and a second position generally perpendicular to the first position;e. means for temporarily securing the second tongue member to the first tongue member in the first and second positions;f. a flip-down leg also mounted on said pivoting means for movement between a first position, in which it extends rearwardly beside said first tongue member, and a second, lowered position in which it extends downwardly from said pivot means and can support the trailer;g. wherein said means for temporarily securing the second tongue member to the first tongue member includes a hitch pin, said hitch pin passes through an aperture in the flip-down leg for supporting the flip-down leg in said first position, and the flip-down leg has a side portion extending rearwardly of said pivot means on one side of the first tongue member, and wherein the said hitch pin is removable from the side of the first tongue member opposite to said one side;the arrangement being such that said hitch pin is movable to a partially withdrawn position where it releases the flip-down leg while the hitch pin still secures the second tongue member to the first tongue member in said first position of the second tongue member, thus allowing said flip-down leg to move to its second, lowered position and to support the trailer while the hitch pin is fully removed and while the second tongue member is moved from its first position to its second position. 5. A method for converting a trailer tongue from a transportation mode into a storage/locking mode, wherein the trailer tongue has a first, tongue member fixed to the trailer, and a second, pivotable, tongue member having a first, front end section with hitching means connectable to the vehicle, a second, rear end section, and an intermediate section between the first end section and the second end section, with pivot means connecting the intermediate section of the second tongue member to the first tongue member for movement of the second tongue member between first and second positions; and means for temporarily securing the second tongue member to the first tongue member in the first and second positions, the trailer tongue also having a flip- down leg also mounted on said pivoting means, a hitch pin for temporarily connecting the flip-down leg and the first tongue member, and a hitch pin for securing the flip-down leg in a vertical position, the method comprising the steps of: a. disconnecting the hitching means on the first section of the second tongue member from the tow vehicle;b. withdrawing said hitch pin from the first tongue member to a partial first position thereby releasing the flip-down leg;c. pivoting the flip-down leg into a substantially vertical position, thereby contacting the ground and supporting the trailer, while the first and second tongue members remain secured together by the partially withdrawn hitch pin;d. withdrawing the hitch pin to a fully detached second position thereby releasing the second end of the second tongue member;e. pivoting the first end section of the second tongue member upward to a vertical position about the pivot means and the second, rear end section of the second tongue member to contact the ground and additionally support the trailer;f. securing the second tongue member in the vertical position by insertion of a locking device connecting the first tongue member and the second tongue member; andg. inserting a hitch pin through both the flip-down leg and the second, rear end section of the second tongue member, thereby further securing the second tongue member in a vertical position.
