Description




FIELD OF THE INVENTION




Suspendible device for holding items, particularly for suspension on a ladder.




BACKGROUND OF THE INVENTION




Suspendible containers are often helpful to users of ladders, scaffolding, ledges and the like. These users often require the containers to hold their tools and other work items. Examples of such tools and items include paintbrushes, cans of paint, and tools used by window washers and builders. The number of possible uses for ladders and elevating apparatus, and the tools required for such uses, is unlimited. The prior art teaches a number of suspendible containers that can be elevated from building surfaces such as ladders, scaffolding and ledges. However, the prior art primarily is limited to containers that clamp to the edges of the top caps or rungs of a ladder or other elevating building surfaces. One such device is described in U.S. Pat. No. 4,480,810 (the “'810 patent”) entitled “Tool and Parts Tray.” The '810 patent discloses a suspendible ladder pan that is attachable to the top cap or rungs of a ladder through the use of an adjustable clamping member.




Many ladders today are manufactured with holes in their top caps. However, none of the prior art teaches a removable suspendible device that can be suspended exclusively from these holes on the top caps of ladders.




SUMMARY OF INVENTION




The present invention relates to a suspendible container for holding items, such as tools and paint cans, that is capable of being attached to a horizontal surface containing holes. At least one prong is attached to a container at one end, and at the other end is removably insertable into the hole on the horizontal surface. Preferably, the container has two prongs, which are adjustable along three dimensions, thereby enabling the container to be attached to a horizontal surface having holes of numerous configurations.




The present invention is particularly adaptable to be suspended from the top cap of a ladder. Top caps of ladders, typically are constructed with holes of various configurations. The adjustable nature of the prongs of the invention enable the container to be suspended from a variety of ladders containing a variety of configurations of holes. In addition, the adjustability of the prongs enables the bottom surface of the container to lay flat even as the ladder is positioned at various levels of inclination. In a preferred embodiment, the dimensions of the container are sufficient for holding tools, paint cans, and other items often needed by the users of ladders. The suspension of the container from the top cap of a ladder enables the user to have access to items inside the container while standing on the ladder.




Because the prongs of the device are removably insertable into a number of ladders, the device is both easy to use, efficient, and economical. The device, however, is not limited to use only with ladders, it may be used on scaffolding or other ledges that contain horizontal surfaces containing holes. In addition, the container could include a removable and/or rotatable lid for protecting items in the container.




In the preferred embodiment, the adjustable prongs are comprised of a horizontal member that is perpendicularly attached to a vertical member. The horizontal member is attached to a flange which is perpendicularly attached to the top edge of one of the sidewalls of the container. The horizontal member is adjustably attached to the flange and the vertical is adjustably attached to the horizontal member.

24


may be attached to flange


52


at a 90 degree angle, thereby creating a perpendicular orientation between the horizontal member


24


and the flange


52


, as seen in FIG.


6


. Alternatively, the horizontal member


24


may be attached to flange


52


at an angle that is greater than or less than 90 degrees, thereby creating a diagonal orientation between the horizontal member


24


and the flange


52


, as illustrated in FIG.

. The horizontal member


24


can be attached to the elongated slot


46


by any adjustable fastener


48


currently known in the art or later developed. Adjustable fasteners that could be used include, pins, screws, bolts, rivets and the like.





FIGS. 6-8

also particularly show the adjustable nature of the vertical member


26


in relation to the horizontal member


24


. In this preferred embodiment, the vertical member


26


is shown in the form of a stove bolt


32


. Each horizontal member


24


contains a channel


50


through which the stove bolt


32


may be inserted. The stove bolt


32


contains a head


54


which is wider than the channel


50


. Accordingly, as the stove bolt


32


is inserted through the channel


50


, the head


54


cannot pass through the channel


50


. A hex-nut


34


is then threadable onto the bottom of the stove bolt


32


to rest against the underside of the horizontal member


24


, thereby holding the stove bolt


32


in place along the channel


50


. As illustrated in

FIGS. 6-8

, the stove bolt


32


can be attached to the horizontal member


24


at any point along the channel


50


, thereby creating a range of adjustability for the stove bolt anywhere along the length of the horizontal member


24


. As a result of the adjustability of both the horizontal member


24


and the vertical member


26


, which in this preferred embodiment is a stove bolt


32


, the device


10


can be suspended from any member of configurations of holes


14


in a horizontal surface


12


.




As discussed above, the flange


52


and the container


16


can be one piece made of the same material. For example, the flange


52


and container


16


can be molded together or can be made from one piece of sheet metal. In another embodiment, the flange


52


and container


16


are separate pieces that are attached to each other.





FIG. 9

illustrates a preferred embodiment of the flange


52


where the flange


52


is comprised of a projecting arm


28


and an attachment arm


30


. Device

is shown in FIG.


10


. In this embodiment, the flange


52


is attached to the container


16


. Preferably, the attachment arm


30


of the flange


52


is attached to the container


16


by welding. However, the manner by which the flange


52


is attached to the container


16


is discretionary. As a result, the flange


52


could be attached to the container


16


by an adhesive, rivets, and the like. In this embodiment, the attachment arm


30


is generally perpendicularly oriented to the projecting arm


28


. Preferably, the projecting arm


28


has a length that is shorter than the attachment arm, and the projecting arm


28


is centrally located along the attachment arm


30


. The horizontal member


24


is attached to the projecting arm


28


, in the manners previously described in relation to

FIGS. 1-8

.




Reference is now made to

FIG. 11

which is another embodiment of the device


58


. In this embodiment, the horizontal member


24


is attached to the top edge of one of the sidewalls


18


directly. In this embodiment, the horizontal member may be adjustably attached to the sidewall


18


by any number of adjustable fasteners currently known in the art or later developed. Alternatively, the horizontal member


24


could be fixedly attached to sidewall


18


. This embodiment also shows an optional lid


42


which may be removably attached to one of the sidewalls


18


.




In an alternative embodiment, the container


16


could be made of two pieces so as to be adjustable in size. As illustrated in

FIGS. 12-14

, this is accomplished by allowing an inner piece


100


to fit inside an outer piece


102


. A folded or formed channel


104


is located on a top edge


106


of the outer piece


102


to hold a top edge


108


of the inner piece


100


allowing them to slide together. Holes


100


are formed through the top edges of both pieces to permit the pieces to be locked together, with a clip


112


, at the desired size. Instead of one flange


52


on the side of the container


16


, there are two shorter brackets


114


, one on the inner piece


100


and one on the outer piece


102


. Each bracket


114


would be designed to allow the same adjustability as the flange


52


. The clip


112


is made to insert through two of the holes


110


on the top edge. The clip


112


has a groove


116


cut in a pin part


118


to allow an “E” ring


120


to snap onto it, thus securing the pin


118


in place. The pins


118


could also be made with a knob


122


on the end causing it to snap in place. Each half of the container


16


would be similar in shape to the original design, but would be 10 ¼″ long, allowing adjust from approximate 14″ to 19″ in length.




Although this invention has been illustrated by reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made which clearly fall within the scope of the invention. The invention is intended to be protected broadly within the spirit and scope of the appended claims.
