The conventional one gallon paint can with a wire bail handle has been in use for more than 150 years, and for more than 150 years users have been frustrated with its design.
A bail handle, often called simply a bail, is a handle made of a wire or the like that rotates about two mounts on the sides of an object that is to be carried. The bail handle is often made of a metal wire but is sometimes plastic or other material. The bail handle is most often associated with a one gallon paint can and other sized paint cans, but is also used for other items, such as buckets, pots, lanterns, and numerous other items or objects.
The first problem with a bail handle, particularly when it comes to bail handles on paint cans, is that it can be uncomfortable to carry. The bail handle can dig into the fingers of a user carrying the paint can. Because of the thinness of the wire of the bail handle, the load is concentrated to a thin strip across one or more fingers. This can lead to achy fingers, especially when the user is carrying the paint can for a long period of time. The discomfort is increased when the paint can is full of paint and/or when a user carries more than one can. Extended carrying and/or repetitive carrying can lead to more severe discomfort or disorders, such as numb fingers and decreased circulation.
A second problem with the conventional paint can is that the can is very difficult to open without the proper tool. A conventional paint can has a friction fit plug type of closure that must be pried off in order to be opened. The prying process requires applying a radially inward force on a lip of the closure and also a lifting force. Often a flat head screw driver, butter knife, keys, pocket knife, or the like is used, but those are not always available to the user of the paint can. Specific paint can pry tools have been developed, but they are hard to keep up with or keep track of and are easily misplaced and/or forgotten.
Therefore, there is a need for a wire handle accessory that reduces the discomfort of using a wire handle to carry an item or object such as a paint can. There is a further need for a wire handle accessory that reduces the discomfort of using a wire handle and is easy to use from any orientation or angle. There is a further need for a wire handle accessory that serves as a paint can opener and that is conveniently locatable and/or storable.

As shown in
The wire handle accessory 100 reduces the discomfort associated with lifting an object 162 with a wire handle 160. The width, w, of the wire portion 161 of the wire handle 160 is often so small that the carrying of the object 162 by lifting the wire portion is uncomfortable for the user. The lower surface 155 of the wire handle accessory 100 has a width in its transverse cross-section that is wider than the width, w, of the wire portion 161. When the wire portion 161 is received within the channel 130 of the wire handle accessory, a user may grasp the lower surface 155 or grasping surface of the wire handle accessory 100 to lift the object 162 rather than directly grasp the wire portion 161. When the user lifts up on the lower surface 155, the bottom surface 140 of the channel 130 lifts up on the wire portion 161 and causes the object 162 to lift when sufficient lifting force is applied. The lower surface 155 thus distributes the weight of the object 162 across a wider surface when the wire portion 161 is contacted directly in the absence of the wire handle accessory 100, thus making the lifting process more comfortable for the user. The wider surface of the lower surface 155 distributes the load over a larger portion of the fingers of the user rather than digging into the fingers and causing discomfort for the user. This improved comfort is even more pronounced when the object 162 is heavy, when the object 162 needs to be carried for a long period of time, and/or when multiple objects 162 are being carried at the same time. The lower surface 155 of the wire handle accessory 100 can have any suitable shape or contour. For example, as shown in
A bail handle 170 is often used with a paint can 180, such as the one-gallon paint can shown in
In one version, such as shown in
In one version, the retention mechanism 190 of the wire handle accessory 100 is designed so that the wire handle accessory 100 is removably attachable to the wire portion 161. In this version, the one or more projections 195 are designed so that they may be deformed under a predetermined about of force so that the wire portion 161 which has a larger width, w, than the undeformed protrusion clearance, p, may pass through the deformed clearance. By making the predetermined amount of force to be greater than the weight of the wire handle accessory 100, the wire handle accessory 100 will be held onto the wire portion 161 by the protrusions 195. When it is desired to remove the wire handle accessory 100 from the wire portion 161, sufficient force is applied to pull the wire portion 161 through the clearance of the protrusions 195 and thereby pull the wire handle accessory off of the wire portion 161. In this manner the wire handle accessory 100 can be used to lift multiple objects 162.

The body 105 of the wire handle accessory 100 can be made of any suitable material sufficiently strong for the intended version. For example, in one version, the body may be composes of one or more thermoplastic, such as one or more of acrylic, acrylonitrile butadiene styrene, nylon, polycarbonate, polyether sulfone, polyoxymethylene, polyetherimide, polyethylenen, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, and the like; metal; alloy; and carbon fiber, and the like. In one particular version, the wire handle accessory 100 comprises acrylonitrile butadiene styrene. In another version, the wire handle accessory 100 comprises polycarbonate. In another version, the wire hand accessory 100 comprises polypropylene. The body 105 can be made of a single piece or multiple pieces that are integrally assembled together.
In one version of the wire handle accessory 100, the body 105 can be designed to make the use and operation of the wire handle accessory 100 more convenient and/or accessible. In one particular version, the body 105, wire handle accessory 100 and/or a portion of either can have one or more axes of symmetry. For example, the body 190 and/or the lower surface 155 of the body 190 can have symmetry with respect to the first end and the second end. In this regard, the lower surface 155 that is to be grasped can be symmetric about a transverse axis that extends from a front side to a back side of the body 190, such as at a midpoint of the body 190 between the first end portion 110 and the second end portion 115. By being symmetric in this manner, the lower surface 155 can be grasped by either the left hand or the right hand of a user without any differences to the feel of the lower surface 155 and/or the ergonomic contour 165. Additionally or alternatively, the body 190 and/or lower surface 155 can have symmetry from front to back about a longitudinal axis that extends from the first end portion 110 to the second end portion 115, such as at midpoint of the body between the front side and the back side. By being symmetric in this manner, the lower surface can be grasped by either reaching from the front of the paint can or other object or from the rear of the paint can or other object without any differences to the feel of the lower surface 155 and/or the ergonomic contour 165.
In one version, the wire handle accessory 100 can be designed to be retained on the wire handle 160 in a manner that does not interfere with the operation of the wire handle 160. For example, the wire handle accessory 100 can be designed to reside substantially within the frame of the wire handle, i.e. in the space between the wire handle 160 and the object 162. In this version, the wire handle accessory 100 can lack any extensions that extend substantially outside the frame of the wire handle 160. More specifically, the wire handle accessory can lack any essential components that extend more than about 1 inch above the frame of the wire handle 160, or more than 05 inches above the frame of the wire handle 160. In one particular version, as shown, the wire handle accessory lacks any portion or any essential portion that extend above the frame of the wire handle 160 by more than the depth of the channel 130.
The shape and dimensions of the body 105 of the wire handle accessory 100 can be selected to suit a desired application. For example, as discussed above, the wire handle accessory 100 can be designed to be attachable onto a conventional one-gallon paint can bail handle. Alternatively, the wire handle accessory 100 can be designed to fit onto any other bail handle or wire handle or any handle that would benefit from a distributed load. When being designed to be attachable to a wire portion 161 of a handle, the distance, c, between the side walls 135 of the channel 130 can be selected to be larger than the width, w, of the wire portion 161 to be received within the channel 130. In one version, for a conventional paint can wire portion 161, c can be chosen to be from about 0.03 inches to about 0.20 inches, more preferably from about 0.11 inches to about 0.14 inches. The one or more protrusions 195 can extend from the sidewall 135 from about 0.005 inches to about 0.06 inches, more preferably from about 0.007 inches to about 0.018 inches. Accordingly, the protrusion clearance, p, can be chosen to be from about 0.07 inches to about 0.13 inches, or can be otherwise selected to be snappable onto a desired wire portion 161. The depth of the channel 130 from the top of the upper portion 120 to the bottom surface 140 can be from about 0.03 inches to about 0.20 inches, more preferably from about 0.11 inches to about 0.14 inches.
The dimensions can be adjusted to fit any desired wire handle or other type of handle, and the above ranges include all included ranges within those ranges.
