FIELD OF INVENTION

The present invention is directed to improvements relating to tool boxes and mounting thereof on a workers cage carried by an extendible and retractable boom and to a tool box for such purpose having a modified lid.

BACKGROUND OF INVENTION

Securing and storing tools and miscellaneous pieces of hardware where they are conveniently available to a worker on the job can often times present a problem as well as present a safety hazard. This can be a particularly serious problem when the worker is in a confined space such as when working in the work cage on an aerial lift boom. Aerial lift booms are conventionally carried on a truck, tractor or the like motorized vehicle and are widely used in the construction trades, utility repair, tree surgery and other similar areas that require access to carry out work in places that may or may not be reached by a ladder. Aerial lift booms are more convenient and more efficient than ladders for use in locations to which the chassis can be moved.
The workers cage is restricted in size and provides only a limited floor area on which to store parts and hand tools that may be required. In addition, the cage, being at the end of the boom, can be unsteady and the presence of items on its floor may present a hazard to the worker. On occasion the worker may wear a tool belt but they can be an impediment for the worker.
Several U.S. patents describe methods and apparatus for holding large tools in the bucket of a boom lift. For example, U.S. Pat. No. 4,194,713 by Johnson describes a tool holder that is secured to a boom lift bucket. The tool holder consists of a bent flexible plate and a tool holding strap extending between opposite edges of the plate. The tool holder is designed to hold elongated tools such as poles and remote mount saws and the like. U.S. Pat. No. 5,878,837 by Kistner, also relates to a tool holder for securing elongated tools on the boom lift bucket. The tool holder is clamped to the upper side edge of the bucket and includes pivotal clamping apparatus for holding the tools. In this manner, the elongated tool can be clamped to the bucket when it is lowered and the tool is lying on the ground. As the bucket lifts the tool, it gradually pivots so that it is safely hanging vertically on the exterior of the bucket.
U.S. Pat. No. 5,261,556 by Gatto relates to a modular tool and hard goods organizer and storage unit for converting the interior of a pail or 5 gallon bucket into a storage unit for such items. This device is unsuited for use in a boom lift bucket since a pail on the floor of the boom lift bucket can interfere with the footing of a worker in the boom lift bucket and thus constitute a hazard.
Containers for boom lift buckets have been used in the field; however, these containers are essentially boxes that are open at the top. Tools and other items are held in the box in a random, unorganized manner. A worker is forced to sort through the items in the box to find the tool or other needed items.
Similar problems are presented in underwater construction and repair projects where a diver requires an assortment of tools to be ready at hand when needed.
Applicants above mentioned U.S. Pat. No. 7,275,641 discloses an organizer for securely retaining hand tools and other miscellaneous small items particularly in environments where space for working is limited and the tools must be organized and conveniently available.
The tool organizer disclosed in applicants above mentioned patent comprises top, front, rear and side faces closed by panels to define top, front, rear and side walls respectively and a bottom wall. The top, front, rear and side walls each define transverse edges and side edges. The bottom wall cooperates with the top, front, rear and side walls to define a container having an interior and a support plate defining an upper and a lower face is disposed in the interior of the container in spaced relationship to the bottom wall for supporting tools and hard goods in an organized and secure manner. At least one of the top or front walls are adapted for movement between a closed position over the top and front face of the container and an open position thereby to expose either the top face or the front face for access into the interior of the container.
In another aspect of the invention the support plate is adapted for hinged attachment in the container for pivotal movement into an essentially vertical position to provide access to the bottom wall of the container for storage of tools and the like when not being used.

SUMMARY OF THE INVENTION

The present invention provides for a tool box and tool organizer, and bracket means for mounting the tool box on a work cage like structure having a horizontal rail, the bracket having thereon a pair of laterally spaced apart downwardly facing hooks to engage and hang from the horizontally disposed rail, the bracket means having a lower portion thereof disposed below the hooks and engagable with the work cage to stabilize the bracket and inter-engagable first and second means respectively on the tool box and bracket detachably mounting the tool box on the bracket.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Illustrated in FIG. 1 is an open framework work cage 10 mounted on the free outer end of an extendible and retractable boom 11. Conventionally the boom is carried by a mobile vehicle (not shown) for movement from one work location to another. The cage has a floor 12, for example made of open mesh metal, and walls 13 extending upwardly from around the periphery thereof. The walls are an open framework comprising a weldment of elongate tubular members and include upper horizontal rails 14, vertical posts 15 and one or more intermediate horizontal rails 16 between the floor and upper rail. The upper and intermediate rails may or may not be in the same plane.
In accordance with the present invention there is provided a tool box (40, 60) and a mounting bracket 20 therefor that detachably mounts the tool box on a wall of the cage. The upper end of the bracket grasps a horizontal rail of the cage and a lower portion of the bracket abuts against other members of the cage wall resulting in the tool box effectively being cantilevered from that wall.
The bracket 20 has two parallel laterally spaced apart elongate posts 21 interconnected by at least one cross member 22. If desired the cross member can be adjustably variable in length to thereby accommodate tool boxes of different widths. Each post 21 is ‘U’ shaped in cross-section and has one or more slots 23 in the web portion thereof. A lug 24 projects outwardly from the upper end of the post 21 and terminates in a downwardly directed portion 25. There is a through hole 26 in the portion 25 for receiving a pin, bolt, lock shaft or the like. An ‘L’ shaped bracket 27 has the free end of one leg thereof pivotally attached as at 28 to the post at a position spaced downwardly from the lug 24. There is a hole 29 proximate the free outer end of the other leg of bracket 27 that can be moved to a position of alignment with the hole 26 for receiving a locking pin The lug 24 together with its downwardly turned end 25 effectively constitutes an inverted ‘J’ shaped hook and the jaw bite portion is opened and closed by pivotal movement of the ‘L’ shaped bracket 27. In the jaw closed position the bracket is securely anchored and lockable to the cage.
The mounting bracket 20 can be readily adapted for use on cages having various wall arrangements. For example not all of the elements that form a cage wall may be in the same plane and this is illustrated by way of example in FIG. 9. In such case the lower portion of the bracket is provide with spacers 95 to engage and abut against an intermediate rail 16 of the wall below the horizontal rail from which the bracket is suspended In FIGS. 4 and 5 the modification includes spacer lugs 96 pivotally attached as at 97 to the lower end of the posts 21.
FIGS. 2, 3, and 15 illustrate a tool box 40 that has a pair of spaced apart end walls 41, respective front and rear walls 42, 43, a bottom wall 44 and a lid 45. The lid 45 is pivotally attached to the rear wall 43 by a hinge means 46 and secured with a pair of latches 51. The tool box 40 has a pair of plates 47 secured to a respective one of end walls 41. Each plate has one or more downwardly facing hooks 48 projecting from an edge thereof beyond the tool box rear wall. In the case of there being two or more hooks on each plate 47 the spacing thereof one from the other corresponds to the spacing of slots 23 in a post 21 associated therewith. Optionally, a handle 39 can be formed as shown in FIG. 15, wherein the embodiment shows a handle formed by a depression in order to remain flush with the exterior surface of the side wall.
As best illustrated in FIGS. 3 and 15, there is a truck or trailer bed floor mounting bracket 99 defined by a longitudinal length of angle iron forming a crossbar 99 with a box end section 98 joining the bottom strip 93 and side strip 97 at its distal ends. Each one of the bottom hooks 48 extending from the rear of the box 40 are insertable in slots 49 formed in the vertical face of the side strip 97 near each of the opposite ends of the tool box that attaches in any convenient manner to the plate 47 associated therewith. Retaining means 91 comprising a tab, locking clip, or the like is removable fastened to the end section 98 of the crossbar 99 and lockably retained by extending a padlock through one or more holes formed through the retaining means and hook 48 or positioning the retaining means such as a tab to project over the top of the hook 48 and securely locking in place to removably secure the box 40 to the crossbar 99 bolted to the truck or trailer bed.
FIGS. 1, 6, 8, and 10-14 illustrate a tool box 60 having a specific lid arrangement particularly for use in confined areas such as is the case with a boom carried work cage 10. The tool box 60 has opposed end walls 61, respective front and rear walls 62, 63 and an open top wall that is selectively opened and closed by a lid 64. The lid comprises panels 65, 66 joined one to the other by first hinge means 70. A second hinge means 80 pivotally connects panel 66 to a flange projecting forwardly from the front wall 62 of the tool box. Each hinge means preferably includes a piano type hinge with hinge means 70 being mounted such that panels 65, 66, in a first partial opening of the tool box, the panels fold one upon the other in face-to-face relation as best illustrated in FIG. 11 and upon continued further opening hinge means 80 brings the panels in their folded state of one upon the other in face to face relation with the outer face of the front wall of the tool box. The tool box and lid in a tool box fully open state occupies minimum space making it suitable for use in confined areas.
The lid panels 65, 66 have respective end flanges 67, 68 at their opposites ends that overlap respectively the outer face of an upper edge of the end walls providing not only an enclosure resisting the entry of water when the tool box is closed but also a tool box with enhanced rigidity. In a lid fully open condition flanges 67 overlap the tool box side walls thereby stabilizing the lid in that position.
The upper edge of the end walls 61 have a first horizontally disposed portion and stepped down from that a second downwardly sloping portion. The rear wall is of greater height than the front wall thus increasing access area to tools in the tool box compared to that of the tool box shown in FIGS. 1 and 2 which has a single panel lid. In a lid closed state panel 65 abuts against the first portion and panel 66 against the second portion.
The interior of the tool box has a plate 100 pivotally attached by hinges 101 to the tool box interior face of the rear wall 63. The plate 100 is spaced a selected distance downwardly from the upper edge of the tool box and has a number of holes 103 of various shapes and sizes for receiving tools and/or parts and pieces useful to a job at hand. The plate 100 covers a selected portion of tool box open top wall and the remaining portion, i.e. the front portion as seen in FIG. 14, is divided into a plurality of variously sized pockets or compartments 104 for receiving tools and/or various parts and pieces. For instance, round apertures 203 are useful for spud wrenches, round apertures 205 for nut drivers, slots 207 for combination squares and/or tape measures, larger apertures 209 hold a battery powered hand drill or drink, smaller apertures 211 are provided for screw drivers, ratchets, circular apertures 213 provide a holder for hammers, rectangular apertures 215 provide holders for pliers, adjustable wrenches, channel locks, locking pliers, and wire cutters. Moreover, removable cups 220 utilizing a peripheral lip 222 may be inserted or dropped into these apertures providing a quick supply and versatile means of quickly providing a selected assortment of tools or parts necessary for a particular job prior to the user being lifted off the ground by the boom.
Hinge means 70 includes a hinge 71 having one plate thereof secured to an outer portion 72 of a ‘J’ shape flange 75 that extends along one longitudinal edge of the lid panel 66. The other hinge plate is secured to a flange 76 extending along a longitudinal edge of lid panel 65. The panel flanges 75, 76 are integral with the respective lid panels and position the hinge pivot axis such that the panels can assume the position seen in FIG. 11. This offset co-relates to the step down in the upper edge portion of the end walls.
Hinge means 80 pivotally connecting the lid to the front wall of tool box comprises a hinge 81 having one plate 82 thereof secured to a flange 83 projecting from the tool box front wall 62 and its other plate 84 secured to a flange 85 projecting from a longitudinal edge of lid panel 66.
The tool boxes 40 and 60 shown in FIGS. 2, 3 and 6-8 have the plate 48 on each of the end walls for detachably connecting the tool box to the bracket 20. In these Figures the plate 48 is shown having a length corresponding to the height of the tool box rear wall. A modified tool box bracket connector plate 110 is shown in FIGS. 10, 11 and 14. The plate is securely attached as by rivets 111 to the tool box end wall and has a pair of spaced apart downwardly facing hooks 49 that engage with correspondingly positioned slots 23 of a mounting bracket 20. The plate 110 has a trunk over-centre latch 112 secured thereto and includes a u-shaped member 113 that engages a catch 114 on the tool box lid panel 65. The pair of latches 51 located one on each of opposite ends of the tool box securely retains the tool box lid in a fully closed state.
The tool box shown in FIGS. 10, 11 and 14 includes a carrying hand grip handle 120 on each of opposite ends of the tool box.
The tool box and mounting bracket therefor has been described in the forgoing in connection with use thereof on the bucket of a boom lift. However, it will be understood that the tool boxes and mounting thereof disclosed will be useful in any situation where tools and other items must be secured and organized for convenient availability, particularly where the work area is somewhat confined.
The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom, for modification will become obvious to those skilled in the art upon reading this disclosure and may be made upon departing from the spirit of the invention and scope of the appended claims. Accordingly, this invention is not intended to be limited by the specific exemplification presented herein above. Rather, what is intended to be covered is within the spirit and scope of the appended claims.
