CROSS REFERENCE TO RELATED APPLICATIONS  
       [0001]    This application claims priority to provisional patent application Serial No. 60/198,984, filed Apr. 21, 2000. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    The invention is related generally to buckets or pails and, more specifically, an improved handle design for use with a bucket, particularly a bucket used by window cleaners on high rise buildings.  
           [0003]    Buckets or pails with handles are known to the art. However, those persons employed as window cleaners or window washers on high rise buildings use buckets containing cleaning liquid or water that must meet certain requirements of the trade. That is, the window washer generally is seated in what is known in the art as a “boatswain chair”. The high-rise window washer accesses windows by swing stage or boatswain chair. The two systems that use the boatswain chair are the Manual Boatswain Chair and the Control Descent System. The Manual Boatswain Chair system uses block and tackle to raise or lower the window washer to the windows. The Control Descent System uses gravity by starting at the roof and repelling over the side. The rate of descent is controlled using a descent device. The descent device regulates the movement down the rope by way of friction. The window washer can descend down to the window and then lock the device until ready to descend to the next window.  
           [0004]    In most cases, the window washer hangs his bucket from on the side of the boatswain chair so that the bucket is accessible. Prior art buckets typically used for hanging on a boatswain chair have several drawbacks. First, to keep the weight down, the buckets usually are plastic with thin, wire handles. The bucket is attached to the boatswain chair by fastening the wire handle onto a snap hook on the boatswain chair. A conventional wire handle can shift or slide along the snap hook and tip or spill. Furthermore, the weight of the liquid in the bucket can cause the handle to pull out or deform the handle or cause the plastic to crack and fail around the handle. Since conventional handles are mounted on the outside of the bucket, weight can cause the bucket to collapse inwardly from the sides where the handle is mounted. Also, since the bucket handle is mounted near the rim and has a substantial curve, the bucket itself is suspended somewhat low relative to the washer seated on the boatswain chair and thus can be inconvenient to use.  
           [0005]    It would be advantageous, therefore, to have a bucket handle for a window washer&#39;s bucket that resists sliding and tipping, resists breaking and bending of the bucket, while allowing convenient access to the bucket by the window washer on the boatswain chair.  
         SUMMARY OF THE INVENTION  
         [0006]    It is among the several objects of the invention to provide bucket or pail with a handle for that resists sliding or tipping when the handle is secured by a clip attached to the center of the bucket handle.  
           [0007]    Another object of the invention is to provide such a bucket and handle which resists damage or distortion of the bucket under load.  
           [0008]    Still another object of the invention is to provide a bucket handle that can be mounted to a conventional bucket or pail.  
           [0009]    Yet another object of the invention is to provide a bucket and handle that provides more convenient access to the bucket by a user seated on a boatswain chair.  
           [0010]    In accordance with the invention, generally stated bucket with a handle that resists sliding or tipping when attached to a hook, that resists distortion and damage when under load, and places the bucket in a convenient proximity to a user in a seated position. In the preferred embodiment, the bucket is a conventionally designed bucket or pail including a replaceable handle on the bucket made from ⅜ inch aluminum rod. The handle has one relatively sharp bend, configured like an inverted V, in the middle of the handle resulting in an apex for attachment to a hook. The handle includes laterally extending, externally threaded mounting extensions at the terminal end of each arm of the V. The handle is mounted inside the bucket and positioned below the rim of the bucket. Each end of the handle is mounted to the bucket wall using an inner and an outer reinforcing plate, each having a central hole formed therein. The reinforcing plates are positioned on each side the bucket wall over a predrilled hole and fastened together with screws, with the bucket wall sandwiched in between the reinforcing plates. The externally threaded lateral mounting extension is inserted through holes in the reinforcing plates and bucket wall and secured with stainless steel lock nuts on the threaded extensions protruding through the bucket wall. A guard can be attached to cover the lock nut to prevent scratching or snagging the structure being accessed.  
           [0011]    The handle can rotate at the mounts, much like a conventional handle. The sharp bend or apex resists sliding when the handled is attached to a hook. The handle is mounted inside the bucket and functions like a brace to prevent the bucket from compressing or collapsing under weight when filled. Because the handle is mounted below the rim, the bucket effectively is raised for easier access, relative to a window washer seated on a boatswain chair when the handle is attached to a snap hook on the boatswain chair.  
           [0012]    These and other objects of the invention will be apparent from a review of the specification and drawings.

       DETAILED DESCRIPTION OF THE INVENTION  
       [0018]    The novel bucket handle is indicated in the drawings by reference numeral  10 . As seen in FIG. 1, handle  10  is attached to a conventional pail or bucket, indicated generally as B. Bucket B can be any type of bucket or pail, but in many applications, bucket B is a 5 gallon plastic pail. In any case, bucket B includes a circumferential side wall W, which can be round, as shown, or rectangular, with a rim R or top edge. The circumferential wall W and the bottom of the bucket define the useful container portion of the bucket, which will be referred to as the inner volume V. As will be appreciated, handle  10  has a generally inverted V configuration, having an body  12  with a centrally positioned apex  14 . The body has a first arm  16  and a second arm  18 . The arms  16  and  18  slope downwardly and are outwardly angled from apex  14 . Arm  16  terminates in laterally extending mounting extensions  20  and arm  18  terminates in laterally extending mounting extension  22 . The extreme ends of the mounting extensions  20  and  22  have external threaded sections  24  and  26 , respectively. In the preferred embodiment, handle  10  is an integral piece formed from metal, for example from ⅜ inch aluminum rod bent into the desired configuration. The apex can be an angle ranging from approximately 90° to approximately 110°, preferably about 100°. However, any appropriate angle formed from any appropriate stock would be acceptable.  
         [0019]    As best seen in FIGS. 1 and 3, handle  10  is mounted with the bucket below the rim R of bucket B. In one preferred embodiment the handle is mounted about 1 inch below the rim, but the handle can be mounted more or less than one inch, depending upon how far below a hook the user desires the bucket to be suspended, as will be explained below. It is preferred that the apex  14  protrude above rim R. A hole H 1  is drilled through the wall of bucket B at a predetermined position. A second hole H 2  is drill through the bucket wall directly across from the first hole. Each end of handle  10  includes the same mounting hardware, as follows. A pair of reinforcing plates  30  and  32 , having holes  34  and  36 , respectively, are positioned over the holes in the bucket wall. As shown, plate  30  is positioned on the inner surface of the bucket wall and plate  32  is positioned on the outer surface of the bucket wall. The threaded ends  20 ,  22  of the handle are inserted through the holes in the plates and the holes in bucket wall, a washer  40  is placed over the ends and a stainless steel nut  42  is tightened on the threads. A U shaped guard  44  with screw holes  46  is positioned over nut  42 . The guard  44  is optional and used to prevent scratching, snagging or catching of the nuts on objects or damage to the mounting apparatus. The plates  30 ,  32  and guard  44  are held tightly in place with and held together with stainless steel screws  48  or the like, with the bucket wall sandwiched in between plates  30  and  32 . It will be appreciated that the holes in the bucket wall and plates are slightly greater in diameter than the diameter of the threaded ends of the extensions so that the handle  10  can rotate in the holes, like a conventional bucket handle. Moreover, the plate prevent the handle from pulling through the plastic and can prevent handle failure, which is an important safety consideration if the bucket is suspended high overhead.  
         [0020]    As can be appreciated by review of FIG. 4, the bucket and handle can be attached to a boatswain chair C. Handle  10 , when secured on a snap hook SH at apex  14 , the hook rests in the apex and will not easily slide or move. If it is displaced, the handle will slide down the arm and come to rest at the angle. Because handle  10  is mounted inside the bucket B, the handle functions as a brace against to prevent collapse of the bucket walls when used with a plastic or thin walled bucket. Also, as seen in FIG. 4, by mounting handle  10  below rim R of the bucket, the bucket itself is effectively is raised relative to the boatswain chair to provide easier access by a user seated on the boatswain chair. As stated above, the bucket can be raised.  
         [0021]    Since handle  10  is fashioned from metal stock and virtually indestructible, when a bucket wears out, the handle and mounting hardware can be removed and installed on a new bucket. Also, for convenient and comfortable hand carrying, the original bucket handle OH can be retained on the bucket and simply rotated out of the way when the bucket is mounted on a boatswain chair, as shown in the drawings.  
         [0022]    It will be apparent to those skilled in the art that various changes and modifications can be made in the novel bucket handle without departing from the scope of the invention. For example, although the novel handle and bucket are described as being used with or suspended from a boatswain chair, it will be understood that the handle allows the bucket to be safely and conveniently suspended from other devices, for example a hook on a ladder or scaffolding. Painters or plasterers may employ such a combination to benefit from the fact that the handle and mounting hardware prevent collapsing of the bucket, damage to the bucket or handle failure. Therefore, the foregoing description and accompanying drawing are intended to be illustrative only and should not be construed in a limiting sense.
