Description




BACKGROUND OF THE INVENTION




This invention relates in general to trailers and, in particular, to a step for a trailer to facilitate access to the load being carried on the trailer.




More specifically, but without restriction to the particular embodiment and/or use which is shown and described herein for purposes of illustration, this invention relates to a trailer step which facilitates access to the load being carried on the trailer, and which includes a lamp which functions to backlight a cutout portion of the trailer step to thereby display, for example, a name, and which can be utilized as a utility lamp for providing a source of light when necessary, and functions as a sidelight to increase the visibility of the trailer when crossing through the path of a vehicle approaching from the side.




Trailers of various types are used to convey or store an almost endless variety of different loads. Certain of these trailers employ the use of steps to facilitate the trailer users getting up onto the trailer for more convenient access to the load being carried, or, for example with boat trailers, to facilitate launching or loading a boat onto the trailer. The present invention provides not only a convenient step for fulfilling this function, but utilizes a lamp to backlight a cutout portion of the step for displaying indicia such as a trademark of the trailer. The lamp which provides the backlighting provides a visual location of the step in the dark, and also functions as a utility lamp to provide light for such things as servicing the trailer or changing tires at night.




SUMMARY OF THE INVENTION




It is, therefore, an object of this invention to improve trailers by providing a lighted step on the trailer.




Another object of this invention is to provide a visual display of backlighted indicia on a trailer step.




A further object of this invention is to provide a visual location of a trailer step for location in the dark.




Still another object of this invention is to provide a built-in utility lamp for use in directing a light source as desired by the user.




Yet another object of this invention is to increase the visibility of a trailer when seen from a vehicle approaching from the side.




These and other objects are attained in accordance with the present invention wherein there is provided a backlighted trailer step to facilitate a trailer users getting up onto the trailer for more convenient access to the load being carried, and which includes a backlighted cutout portion of the step which displays indicia such as a trademark of the trailer. The lamp provides a visual locator for the step in the dark, and also functions as a utility lamp to provide light for such things as servicing the trailer or changing tires at night. The light emitted from the side also enhances the visibility of the trailer to vehicles approaching from the side.

DESCRIPTION OF A PREFERRED EMBODIMENT




Referring now to the drawings, there is illustrated a preferred embodiment of the invention utilized on a boat trailer


10


. However, it is to be understood that the use of the invention on a boat trailer is for purposes of illustration of a preferred embodiment, but the use of the invention is not intended to be limited to boat trailers. As is known to those skilled in the art, trailers include a pair of side frame members, or side booms,


15


which have a spaced parallel load-supporting portion


15




a


upon which an object is carried, and a forward converging or tongue-forming portion


15




b


through which the trailer is connected to a towing vehicle by means of a trailer hitch coupling


16


. As shown in

FIG. 1

, the trailer


10


generally will include a tongue jack


11


and winch


12


with a bow stop


13


.




A trailer step


20


is secured to a side frame member or side boom


15


, as by welding, and includes a reflector


21


. To secure the step to the trailer, a plurality of side or cross braces


22


, illustrated as four, are welded at one end to the side boom


15


and at the other end to a face plate


25


. The face plate


25


is also welded at a forward end


25




a


to the trailer side boom.




As shown in

FIGS. 1 and 3

, the face plate


25


is referably of a size or depth equal to the face of the side boom


15


which adds to the structural integrity of the step, and improves the appearance of the trailer. Preferably a diamond pattern non-slip surface


26


forms a cover for the step to close the open grid formed by the side braces


22


and face plate


25


, and is secured to the side or cross braces


22


by riveting. A rear end


25




b


of the face plate is curved to conform to the curvature of a fender


14


to which it is welded, for enhancing the appearance of the trailer. A fender brace


23


is welded between the rear end of the face plate


25




b


and the trailer side boom


15


to increase support for the step, and to attach the fender


14


to the trailer.




As best illustrated in

FIGS. 1

,


3


and


5


, the face plate


25


is formed with indicia


24


, such as a name or trademark, by cutting or removing a portion of the face plate in a desired indicia-forming configuration. A translucent or non-opaque piece of material


27


, preferably of a colored plastic, is secured to the interior side of the face plate


25


such that the colored material


27


can be seen through the portions of the face plate which have been removed, thereby prominently displaying the desired indicia.




To enable the indicia to be seen at night, and for facilitating locating the step in the dark and increasing the visibility of the trailer at night to traffic approaching from the side, the interior of the step is lighted to backlight the indicia


27


formed in the face plate


25


. To this end a light bar


28


is secured to the cross braces


22


and the face plate


25


, as by welding, for supporting a series of lamps


29


connected to the trailer lighting system. When illuminated, these lamps


29


provide a source of light which is visible through the material


27


and the cut-out portion of the face plate


25


. In the event it becomes necessary to service the trailer at night, such as when changing a flat tire, the lamps


29


can be used for illuminating the tire area to facilitate the changing of a flat tire.




While this invention has been described in the specification and illustrated in the drawings with reference to a preferred embodiment, the structure of which has been disclosed herein, it will be understood by those skilled in the art to which this invention pertains that various changes may be made and equivalents may be substituted for elements of the invention without departing from the scope of the claims such as, for example, changing the specific indicia illustrated herein, the shape of the step, or using the step on a different type of trailer. In addition many other modifications, such as changing the number of lights or cross bars illustrated in the preferred embodiment, eliminating the diamond pattern non-slip surface on the top of the step, or using a non-slip surface of a different pattern or type, could be done. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed in the specification and shown in the drawings as the best mode presently known by the inventor for carrying out this invention, nor confined to the details set forth, but that the invention will include all embodiments, modifications and changes as may come within the scope of the following claims:
