Description
Background of the Invention
Various forms of trailer tongue stands heretofore have been provided. However, most trailer tongue stands are vertically adjustable and are used primarily in conjunction with trailers which may experienced heavy tongue loadings. While these adjustable tongue stands function as desired and with high reliability, they are expensive and not required on trailers which do not experience high tongue loadings. Therefore, a need exists for a lightweight inexpensive trailer tongue stand which may be used, when desired, to support the tongue of a trailer in an elevated position above the ground.
Examples of various different forms of trailer tongue stands including some of the general structural and operational features of the instant invention are disclosed in U.S. Pat. Nos. 2,571,390, 2,631,862, 2,865,658, 2,969,885, 3,643,975, 3,791,676, 3,989,276, and 4,294,088.
Brief Description of the Invention
The trailer tongue stand of the instant invention is of lightweight construction and its major components may be readily constructed of channel members of different sizes and lengths. The trailer tongue stand incorporates a leg assembly swingable between a rearwardly projecting and horizontally disposed retracted position and a downwardly extended and slightly forwardly inclined extended position. The tongue stand may be readily operatively associated with trailer tongues of different cross sectional dimensionals and further includes structure defining a spare tire carrier as well as means by which the stand may be locked in either the downwardly extended or upwardly retracted positions and associated spare tire may be locked against unauthorized removal.
The main object of this invention is to provide a trailer tongue stand for lightweight trailers and which may be readily mounted upon trailer tongues of different cross sectional sizes.
Another object of this invention is to provide a lightweight trailer tongue stand for trailers which are not subject to heavy tongue loading.
A further object of this invention provide a trailer tongue stand also incorporating a spare tire mount.
Yet another important object of this invention is to provide a trailer tongue stand which may be constructed from readily available and inexpensive components.
A final object of this invention to be specifically enumerated herein is to provide a trailer tongue stand in accordance with the preceding objects and which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

Detailed Description of the Invention
Referring now more specifically to the drawings, the numeral 10 generally designates a boat trailer of conventional design including a forwardly projecting tongue 12 having a socket hitch assembly 14 mounted on its forward end.
The combined trailer tongue stand and spare tire mount assembly of the instant invention referred to in general by the reference numeral 16 and is mounted on the tongue 12 intermediate the socket hitch assembly 14 and the tongue mounted bow stop 18 of the trailer 10.
The assembly 16 includes a channel member 20 having depending first and second opposite side flanges 22 and 24 interconnected at their upper marginal edges by an upper bight portion 26. The bight portion 26 includes opposite side pairs of front and rear slots 28 and 30 formed therein and inverted carriage bolts 32 have their shank portions passed upwardly through the slots 28 and 30 and passed through similar pairs of opposite side front and rear slots 34 and 36 formed in the bight portion 38 of an upper upwardly opening channel member 40. The upper ends of the carriage bolts 32 are secured through the slots 34 and 36 by threaded nuts 42. The slots 28, 30, 34 and 36 extend transversely of the corresponding bight portions 26 and 38 and therefore enable the carriage bolts 32 to be spaced different distances apart in order to accommodate trailer tongues 12 of different widths therebetween.
A generally U-shaped leg assembly is provided and referred to in general by the reference numeral 44. The leg assembly 44 comprises an elongated channel member 46 which is bent into generally U-shaped configuration defining opposite side legs 48 and 50 interconnected at their lower ends by an integral horizontal cross piece or bight portion 52. The upper end portions 54 of the legs 48 and 50 are generally parallel and slightly angulated relative to the remaining downwardly divergent lower portions of the legs 48 and 50. A first pivot fastener 56 secures the upper end portion 54 of the leg 48 to an upper portion of the flange 24 and a second longer pivot fastener 58 pivotally secures the upper end portion 54 of the leg 50 to the upper portion of the flange 22. The pivot fastener 58 includes a compression spring 60 which serves to yieldingly bias the inner side of the upper end portion 54 toward the outer opposing surface of the flange 22 for a purpose to be hereinafter more fully set forth.
The forward lower corner portions of the flanges 22 and 24 have an abutment member 62 extending therebetween and secured therethrough and the opposite ends of the abutment member 62, which project outwardly of the flanges 22 and 24, are abuttable by the upper end portions 54 of the legs 48 and 50 to limit pivotal movement of the leg assembly 44 toward the downwardly projected and slightly forwarded inclined extended position thereof illustrated in FIG. 1. In addition, the flange 22 includes a pair of outwardly projecting integral detents 64 and one of the detents 64 is disposed immediately behind the upper end portion 54 when the leg assembly 44 is in the downwardly extended position thereof illustrated in FIG. 1 and the other detent is disposed immediately beneath the upper end portion 54 of the leg 50 when the leg assembly 44 is swung rearwardly and upwardly toward an upwardly retracted rearwardly projecting horizontal position. Thus, the detents 64 yieldingly retain the leg assembly 44 either in the downwardly projected position thereof illustrated in FIG. 1 or an upwardly retracted horizontal and rearwardly projected position closely underlying the tongue 12.
The flange 24 includes first and second bores 68 and 70 formed therethrough and it will be noted that the bore 70 is disposed immediately behind the upper end portion 54 of the leg 48 when the leg assembly 44 is downwardly extending position, see FIG. 2. Also, from the phantom line position of the leg assembly shown in FIG. 2, when the leg assembly is in the upwardly retracted position the bore 68 is disposed immediately beneath the upper end portion 54 of the leg 48.
The hasp 72 of a padlock 74 may be passed through the bore 68 in order to lock the leg assembly 44 in the raised position or through the bore 70 in order to lock the leg assembly 44 in the downwardly extended position. It is to be noted that the bores 68 and 70 are formed in the flange 24 while the spring biased pivot connection 50, 60 is operatively associated with the flange 22, the pivot fastener 56 not allowing lateral outward displacement of the upper end portion 54 of the leg 48 relative to the flange 24.
The central portion of the bight portion 38 includes a center longitudinally extending slot 76 formed therein and the lower end of an inverted carriage bolt 78 projects upwardly through the center slot 76. The head of the carriage bolt 78 is, of course, held captive between the bight portion 38 of the channel member 40 and the upper surface of the tongue 12, see FIG. 3.
A centrally apertured downwardly opening channel member or bar 80 is provided and upwardly receives the upper end of the carriage bolt 78 therethrough. The channel member 80 may be disposed across the centrally apertured hub portion 82 of a spare tire wheel 84 and channel member 80 may be tightly secured in position by a nut 86 threadedly engaged with the carriage bolt 78. In addition, one end of a link chain section 88 is anchored relative to the channel member 80 and the other end of the link chain section 88 is passed downwardly through the center of the wheel 84 and has the hasp 72 of the padlock 74 engaged therethrough. Even though a wrench may be engaged with the nut 86 to remove the same, the length of the link chain section 88, when one end thereof is anchored to the padlock hasp 72 in the manner illustrated in FIG. 3 of the drawings, is not sufficient to enable the channel member 80 to be passed upwardly off the upper end of the carriage bolt 78. Further, the nuts 42 which secure the carriage bolts 32 in position are maintained in a unaccessible position by the spare wheel 84. Accordingly, the padlock 74 not only serves to lock the leg assembly 44 in the downwardly extended position in the manner illustrated in FIG. 2 of the drawings but also to lock the spare wheel 54 against removal from the trailer tongue 12.
Of course, the hasp 72 of the padlock 74 may be passed through the bore 68 in order to lock the leg assembly 44 in the upper rearwardly projecting position. Here again, when the hasp 72 of the lock 74 is passed through the bore 68, the length of the link chain section 88 is not sufficient to enable the channel member 80 to be upwardly displaced from the upper end of the carriage bolt 78.
The leg assembly 44 is stiff and substantially rigid but may be flexed at least somewhat against the biasing action of the spring 66 in order to allow the upper end portion 54 of the leg 50 to pass over both of the detents 64 when the leg assembly 44 is swung either from the raised position to the fully downwardly extended position or from the fully donwardly extended position to the raised position. The detents 64 are formed in the flange 22 merely by outwardly deforming portions of the flange 22.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
