Description
Background of the Invention
1. Field Of The Invention
This invention relates to portable containers, and more specifically concerns portable containers which may be attached to a ladder for holding work tools, such as hammers, screwdrivers, caulking guns, and the like.
2. Description Of The Prior Art
In the prior art, attempts have been made to allow a worker who works on a ladder, such as a painter or a siding mechanic, to have his tools and equipment in a convenient place at the top of a ladder so that he does not have to carry his tools with him each time he goes up and down the ladder.
One solution to this problem has been for workers to wear a specially designed leather belt to hold their tools. The leather belt typically includes pockets for holding a hammer, screwdrivers, nails, tape measures, and the like. Such leather belts are usually thick and wide, and weigh the worker down when he moves up and down the ladder with all of his tools in his belt. The leather belt is dangerous, because if the worker falls from the ladder he may be severely injured by falling upon sharp objects such as screwdrivers and knives and heavy objects such as hammers that are in his belt.
Another problem with a leather belt is it usually has no place to hold a caulking gun, which makes the caulking gun one of the most difficult tools to use while on a ladder because there is no convenient place at the top of a ladder to put it when it is not in use. If it is attempted in some way to attach the caulking gun to the worker's leather belt, the size of the caulking gun restricts his movement and can also leak caulking from the tip of the gun onto the worker's clothing.
A particularly dangerous tool to use at the top of a ladder is a blow torch. Painters often use blow torches to remove old layers of paint. When a blow torch is not in use, it is dangerous because it is heavy and may fall and injure someone, and because after use it is hot at the tip, and may easily burn the user.
In recent years, attempts have been made to provide support trays for attachment to a ladder, such as is shown in U.S. Pat. No. 4,222,541, which discloses a tray secured to the side of a step ladder by a series of brackets that are held together by nuts and bolts.
A problem with these types of containers is that they difficult and time-consuming to install. The installation of the tray shown in U.S. Pat. No. 4,222,541 requires that the worker position a first bracket having two studs against the side of the ladder with one hand, and then place a second bracket, which is attached to the tray, through the studs of the first bracket. While holding the assembly in place with one hand, the worker's free hand threads wing nuts onto the bolts. The bolts are then tightened to secure the tray to the ladder. If the worker moves to a different position on the ladder to work, the bracket assembly must be taken apart and reassembled at the new position on the ladder.
Workers in the construction industry, and particularly the painting and siding industries, are often paid by the job, and not by the hour. Therefore, it is of utmost importance that the worker be able to move quickly up and down a ladder as he performs his work, because in that way he makes more money. A worker does not have the time required to constantly disassemble and reassemble a set of brackets held together by nuts and bolts each time he must move to a different position on the ladder.
Summary of the Invention
It is an object of this invention to provide a container for holding a worker's tools that is quickly and easily attached to and detached from a stationary support such as a ladder.
Another object of the invention is to provide a container that holds tools that are awkward for a worker to use on a ladder, such as caulking guns, screwdrivers, hammers and the like.
Still another object of the invention is to provide a container which may be attached to a variety of stationary objects, including an extension ladder, a step ladder, scaffolding, and a worker's leg.
A further object of this invention is to provide a container that allows for greater safety in use of tools on top of a ladder, including heavy and dangerous items like blow torches.
In accordance with these and other objects of the invention, there is shown a container that is quickly and easily attached to a ladder and quickly and easily detached and moved to another position on the ladder while providing a stable and secure attachment to the ladder.
The invention includes a container having a square base and four side walls with a bungee cord having hooks at both ends wrapped around the outside walls of the top of the container and hooked around the ladder or other structure it is desired to hold the container against. To strengthen the attachment to the adjoining structure and to stabilize that attachment, a second bungee cord having hooks may be wrapped around the bottom side walls of the container and around the structure the container is to be held against.
The bungee cords are held in the proper position against the container by belt loops that are formed in a side wall of the container. The belt loops are located at different heights on the side wall with one bungee cord passing through one belt loop. The belt loops form an opening that is approximately the same size as the thickness and width of the bungee cord so that the bungee cord snugly fits into the belt loop.

Detailed Description
Turning now to the drawings, there is shown a container 11 having a bottom wall 13 and four upwardly depending side walls 15. Container 11 may be constructed of any durable material, such as plastic, metal or wood.
Container 11 includes means located around the outside of side walls 15 for demountably attaching container 11 to a stationary support, such as ladder 17. The attaching means may include elastic cords such as bungee cords 19 which wrap around container 11. Bungee cords 19 have hooks 21 which are attached at both ends of each bungee cord 19 and provide a means for hooking the ends of bungee cords 19 together around container 11 and ladder 17 for securely holding container 11 in place.
One of said side walls 15 includes means formed therein for positioning and supporting the bungee cords 19 on the container 11. The supporting means includes a pair of belt loops 23 formed in side wall 15. In a preferred embodiment, belt loops 23 are C-shaped and form an opening wide enough for bungee cords 19 to easily pass therethrough, but at the same time provide a snug fit to prevent the bungee cords 19 from easily slipping out of belt loops 23. Belt loops 23 are preferably positioned at different heights along said side wall 15 to provide a secure and stable attachment of container 11 to ladder 17.
Bottom wall 13 may include drain hole 25 to allow for the drainage of water which may collect in container 11.
In operation, container 11 is filled with work tools and carried to a desired position on ladder 17 where bungee cords 19 are wrapped around the side of ladder 17 and hooks 21 are hooked together to securely attach container 11 to ladder 17. Bungee cords 19 are preferably positioned and hooked just above the rungs of ladder 17 to prevent container 11 from slipping down the side of ladder 17. Container 11 may be attached to either the right-hand side or left-hand side of ladder 17.
Container 11 is not limited to being attached only to ladder 17, but may be attached to any object that will make it convenient for a worker to reach his tools, such as scaffolding or a railing. Container 11 may also be attached to a worker's leg.
The preferred attaching means is bungee cord 19, but any other type of mounting cord can be used, such as a piece of rope as long as it provides a secure attachment of container 11 to ladder 17.
The bungee cords 19 shown in FIGS. 1 and 2 are long enough to wrap around container 11 and ladder 17, but this length is for illustrative purposes only. The length of bungee cords 19 may be varied depending upon the type of support against which container 11 is to be mounted. For example, mounting container 11 against a thick support column (not shown) requires longer bungee cords 19.
Container 11 may include only one belt loop 23 and one bungee cord 19, but it is preferred to have two belt loops 23 and two bungee cords 19 to provide stability to container 11 when it is attached to ladder 17.
Bottom wall 13 is shown to be square, but it may have a shape other than flat and square, without departing from the spririt of the invention.
Turning to FIGS. 3-6, there is shown another embodiment of the invention, container 11a.
Container 11a has a bottom wall 13a, front wall 31, side walls 33, 35 and rear wall 37.
Bungee cords 19a (FIG. 6) are wrapped around outside walls 31, 33, 35, 37 for demountably attaching container 11a to a stationary support, such as ladder 17a. Bungee cords 19a have hooks 21a which are attached at both ends of each bungee cord 19a and provide a means for hooking the ends of bungee cords 19a together around container 11a and ladder 17a for securely holding container 11a in place.
A pair of belt loops 23a are formed in front wall 31 at different heights thereon. Belt loops 23a include openings which allow bungee cords 19a inserted therethrough for attaching it to a ladder 17a.
Container 11a further includes a U-shaped channel 39 formed at the top of side wall 33, front wall 31, and side wall 35. Channel 39 is wide enough to hold a variety of small items, such as wing nuts, bolts, nuts, screws and the like, and still allow a workman to grasp the items with his fingers and remove the items therefrom. Channel 39 allows easy access to small items which otherwise would be stored on bottom wall 13a of container 11a, where their retrieval would be difficult.
Channel 39 is formed on the outside of walls 31, 33 and 35, so as not to take away from the size of the opening in container 11a. There is n U-shaped channel formed at the top of rear wall 37 because wall 37 must be flush against a ladder 17a.
A removable divider or partition 41 (FIG. 4) is disposed in container 11a between front wall 31 and rear wall 37, and divides container 11a in half to form two separate interior chambers. Divider 41 is held in place by a slot 43 formed in front wall 31 and a slot 45 formed in rear wall 37.
Removable divider 41 is particularly useful when it is desired to separate certain tools from each other. For example, on one side of divider 41 a workman may keep paint brushes, stirrers and other work instruments which may be coated from time to time with paint. On the other side of divider 41, the workman may keep his screwdrives, pliers and the like so as not to get paint on his tools. When it is desired to utilize the full volume of container 11a, divider 41 is removed.
An outwardly extending handle 47 is formed in side wall 35 of container 11a with the top part of handle 47 located below channel 39 and the bottom part of handle 47 located between bungee cords 19a. It is important that handle 47 be positioned on side wall 35 such that it does not interfere with bungee cords 19a when they are attached to a ladder 17a.
Handle 47 allows a worker to carry container 11a easily from place to place when it is not in use. Also, handle 47 allows a worker to safely carry a container 11a up a ladder 17a when container 11a is filled with heavy tools.
Roller brush holder means, comprising a pair of L-shaped flanges 49, are formed in front wall 31 below bungee cords 19a and belt loops 23a. Flanges 49 permit a worker to safely store a roller brush on the outside of container 11a. Roller brushes are usually T-shaped and have handle portion formed at the bottom of the "T", and a rotatable cylinder and brush formed at the top of the "T". A roller brush, because of its unusual shape, does not fit easily inside container 11a and is clumsy and awkward to carry to the top of a ladder. L-shaped flanges 49 eliminate the problem of carrying roller brushes and allow them to be easily and safely stored.
Sanding pole holder means, comprising a second pair of L-shaped flanges 51, project outwardly from side wall 33. Flanges 51 are sized to hold a work instrument, such as a sanding pole holder. A sanding pole holder is a common work instrument in the painting industry, and comprises a handle such as a broom stick and a square flat surface top which holds a piece of sandpaper attached at the top of the handle. A painter grasps the handle and uses the sandpaper to sand places that are hard to reach. Such a work instrument is conveniently held outside container 11a on L-shaped flanges 51.
A drain hole 25a (FIG. 4) may be formed in bottom wall 13a of container 11a to drain liquids, such as rain water from the container. A plug 53 (FIG. 3) is provided which, when placed in drain hole 25a, prevents the passage of liquid therethrough. It may be desired to use container 11a as a paint can, in which case plug 53 is placed in drain hole 25a and container 11a is filled with paint or another liquid. Container 11a is an excellent paint can because it may be attached securely to a side of a ladder 17a while in use. When the worker is finished painting, plug 53 is removed from drain hole 25a, and container 11a is drained and cleaned for further use as a container for holding work instruments and the like.
A shelf 55 is formed inside container 11a on the inside of side wall 33, and a shelf 57 if formed inside container 11a on the inside portion of side wall 35. Shelves 55, 57 are positioned near the top of side walls 33, 35 and extend inwardly towards the center of container 11a. Shelves 55, 57 are useful when container 11a is used as a paint can, because they provide a surface against which a paintbrush that has been dipped in paint may be wiped against to remove excess paint from the brush.
FIG. 6 shows that in a preferred embodiment of the invention, the bungee cord 23a and hooks 21a nearer to the top of container 11a rest on top of a rung of a ladder 17a.
