A latch to secure folding implements in a transport configuration. The latch is constructed so as to permit selective disengaging of the latch to allow the folding implement to be configured for operation. A latching mechanism with a pivoting portion engages a crossbar in latching. One of the latching mechanism or pivoting portion is suspended on an extension bar which is cantilevered and suspended from either a main frame or a folding arm. The latching system tolerates misalignment of the main frame and folding arms through the suspension system.

1. A towable implement comprising: (a) a cart comprising a plurality of wheels and a towing bar;(b) at least one folding arm pivotally supported by the cart, each folding arm being configured to widen into an operative working position and narrow into an implement transport position, each folding arm having a free arm end, the free arm end having a folding arm latch location associated therewith;(c) at least one respective implement unit operatively mounted to each folding arm;(d) at least one extension arm, the at least one extension arm being independently and pivotably mounted on the cart, the at least one extension arm comprising at least one extension arm end;(e) at least one latch mechanism carried by a corresponding said extension arm and thereby operatively, independently, and movably mounted relative to the cart, the at least one latch mechanism being selectably, releasably connected to a corresponding folding arm at a corresponding folding arm latch location of a given folding arm; and(f) a given biasing suspension system for each said extension arm, the given biasing suspension system being attached to the cart and the corresponding said extension arm, the biasing suspension system being configured to the extension arm in a manner so as to favor alignment relative to a corresponding folding arm latch location. 2. The towable implement of claim 1, wherein the at least one latch mechanism comprises a latch element, operatively, pivotally attached to an extension bar end, the latch element being configured for operatively engaging a corresponding folding arm at a given folding arm latch location. 3. The towable implement of claim 2, wherein each folding arm latch location includes a crossbar configured for being operatively, releasably engaged by the at least one latch mechanism. 4. The towable implement of claim 3, further comprising a respective biasing mechanism operatively attached to the at least one latch mechanism, the respective biasing mechanism operates to bias the given latch mechanism toward the corresponding crossbar when the at least one latch mechanism and the corresponding crossbar are in a latch engagement position. 5. The towable implement of claim 2, additionally comprising a corresponding latch release associated with a respective latch mechanism, the corresponding latch release being configured for being selectively moving the corresponding latch element away from the corresponding folding arm latch location of the corresponding folding arm and out of engagement therewith. 6. The towable implement of claim 5, wherein the corresponding latch release comprises a pull cord, the pull cord being operatively attached to the respective latch element. 7. The towable implement of claim 5, wherein the corresponding latch release is actuated by at least one actuating device selected from a group consisting of a mechanical actuator, an electric actuator, a pneumatic actuator, an electromagnetic actuator, and a hydraulic actuator. 8. The towable implement of claim 1, wherein the towable implement unit comprises a hay rake. 9. The towable implement of claim 1, wherein a given said latch mechanism comprises a stationary V-shaped receiver member configured to facilitate receiving of a corresponding folding arm latch location therein. 10. A towable implement, comprising: (a) a cart provided with a plurality of wheels and a towing bar;(b) at least one folding arm pivotally supported by the cart, the at least one folding arm being configured for being widened into an operative working position and narrowed into an implement transport position, the at least one folding arm having a corresponding free arm end, the corresponding free arm end defining a corresponding latch location;(c) at least one respective implement unit operatively mounted to the at least one folding arm;(d) at least one extension arm, the at least one extension arm being independently and pivotably mounted on the cart, the at least one extension arm comprising at least one extension arm end;(e) at least one folding arm latch mechanism carried by a corresponding said extension arm and thereby operatively attached to the cart, the at least one latch mechanism being selectively, releasably attached to the at least one folding arm latch mechanism and thereby holding the at least one folding arm in the implement transport position thereof; and(f) a given biasing suspension system for each said extension arm, the given biasing suspension system being attached to the cart and the corresponding said extension arm, the biasing suspension system being configured to bias the extension arm in a manner so as to favor alignment relative to a corresponding folding arm latch location. 11. The towable implement of claim 10, wherein the at least one latch mechanism comprises a latch element pivotally attached to the cart, the latch element being configured for operatively engaging a corresponding latch location of a given free arm end of a corresponding folding arm. 12. The towable implement of claim 11, wherein a given latch location includes a crossbar configured for being operatively, releasably engaged by the at least one latch mechanism of the cart. 13. The towable implement of claim 12, further comprising a respective biasing mechanism operatively attached to the at least one latch mechanism and the corresponding crossbar, the respective biasing mechanism operates to bias the given latch mechanism toward the corresponding crossbar when the at least one latch mechanism and the corresponding crossbar are in a latch engagement position. 14. The towable implement of claim 11, additionally comprising a corresponding latch release associated with the at least one latch mechanism, the corresponding latch release being configured for selectively moving the corresponding latch element away from the corresponding folding arm latch location of one of the said corresponding folding arms and out of engagement therewith. 15. The towable implement of claim 14, wherein the corresponding latch release comprises a pull cord, the pull cord being operatively attached to the respective latch element. 16. The towable implement of claim 14, additionally comprising at least one actuating device for the latch release selected from a group consisting of a mechanical actuator, an electric actuator, a pneumatic actuator, an electromagnetic actuator, and a hydraulic actuator. 17. The towable implement of claim 10, wherein the towable implement unit comprises a hay rake. 18. A towable implement comprising: (a) a cart comprising a plurality of wheels and a towing bar;(b) a folding arm pivotally supported by the cart, the folding arm being configured to widen into an operative working position and narrow into an implement transport position, the folding arm having a free arm end, the free arm end having a folding arm latch portion associated therewith;(c) at least one respective implement unit operatively mounted to the folding arm;(d) an extension arm independently and pivotably mounted on the cart, the extension arm comprising a first extension arm end, the first extension arm end carrying an extension arm latch portion, one of the folding arm latch portion and the extension arm latch portion comprising a latch mechanism being selectably, releasably connected to a corresponding other of the folding arm latch portion and the extension arm latch portion; and(e) a given biasing suspension system for each said extension arm, the given biasing suspension system being attached to the cart and the corresponding said extension arm, the biasing suspension system being configured to bias the extension arm in a manner so as to favor alignment relative to a corresponding folding arm latch location. 19. The towable implement of claim 18, wherein the latch mechanism comprises a stationary V-shaped receiver member configured to facilitate receiving of the other of the folding arm latch portion and the extension arm latch portion therein, the latch mechanism further comprising a pivoting latch element rotatably attached to the V-shaped receiver member. 20. The towable implement of claim 18, wherein the given biasing suspension system comprises a spring member.
