This invention relates to a support bracket that may be attached to a ladder for supporting an object holding accessory adjacent and to one side of the ladder. The accessory may be a holder for a paint can, or a holder for a paint roller pan, or the like. This invention also relates to paint can and paint roller pan holders themselves.
It is difficult when working on a ladder to carry and hold tools, brushes, and/or materials. For example, when a person stands upon one of the rungs of a ladder to paint the side of a structure, it is necessary to hold the paint can in one hand and the brush in the other, all the while maintaining one's balance on the ladder. This is tiring and difficult to do especially over long periods of time. It would not be unusual for a person so situated to drop the brush or spill paint from the can. This leads to unwanted and messy stains which must be cleaned up.
Various devices have been proposed for attachment to a ladder to assist the user in supporting a paint can or in holding tools. Many of these devices are designed to fit or clamp around central portions of one or more of the ladder rungs. When in place, these devices cover at least a portion of a rung that is located above the rung on which the user is standing. If the user wishes to ascend further up the ladder, such passage may be blocked, or at least made more difficult, by the installed device. The device might first have to be removed from the ladder to allow the user to proceed further up the ladder.
Other object holding accessories for a ladder are installed by inserting at least a portion of the accessory into one end of one of the rungs of a hollow rung ladder. For example, U.S. Pat. No. 5,259,525 to Wion shows a paint can holder having a handle or support arm that fits inside a hollow ladder rung. A wedge can be pounded in to wedge or lock the support arm in place.
Some ladder accessory devices are supported on brackets that fit around a side rail of the ladder. One such device is disclosed in U.S. Pat. No. 5,826,844 to Purdy. In the Purdy device, a U-shaped bracket fits around a ladder side rail with an outer wall of the bracket having two slots through which a strap may be threaded. The strap can be tightened around a paint can to support the paint can.
The Purdy device has various disadvantages. If the bracket is installed on the side rail before the strap is inserted, it would be difficult to thread the strap through the slots as these slots would be very close to, if not covered by, the side rail itself. If one attempts to thread the strap and install the paint can before the bracket is installed on the side rail, then it would be awkward and difficult to install the bracket without spilling paint from the paint can. Moreover, the strap is useful only for supporting a tubular type container, such as a paint can, and is not adaptable for holding other things on the side rail of the ladder. Thus, the Purdy bracket and strap system is quite limited in what can be attached to the ladder and would be difficult to install.
U.S. Pat. No. 2,895,700 to Johnson discloses a support bracket that is attached to the side rail of a ladder. The bracket includes outwardly turned flanges having two pairs of aligned vertical holes. A paint can holder in the form of a circular ring has a pair of downwardly extending feet that slip into the pairs of holes on the flanges to support the ring to one side of the ladder in a cantilever fashion. Paint cans of various sizes are then dropped into and supported by the ring. Thus, the Johnson support bracket is able to support the paint can holder without using a flexible strap that has to be threaded through slots in the bracket.
While the brackets shown in the Johnson and Purdy patents are useful in holding paint cans and the like to one side of a ladder, they have various disadvantages. Ladders have differently sized and shaped side rail and rung configurations. Thus, a particular bracket might work well with one ladder but not another. And, even when a bracket purports to be somewhat adjustable, like the bracket of Johnson, the adjustment is somewhat clumsy and time consuming to do. Thus, it will take some time for the user to properly adjust the bracket and install it on the ladder side rail. There is a need in the art for a support bracket that is truly universal in the sense of fitting almost every ladder on the market, but yet is quick and easy to install and uninstall.
In addition, most known brackets are used for supporting a particular object holding accessory that is designed for the particular bracket. As an example, the Johnson patent shows a circular ring for holding a paint can. The paint can is specifically designed with the downwardly extending feet that are necessary to drop the ring down onto the Johnson support bracket. This same structure is not disclosed as being useful for holding other things, such as a paint roller pan.
Moreover, paint roller pans have different characteristics from paint cans and must be supported more carefully than paint cans since the paint in an open paint roller pan is more prone to being spilled than the paint in a paint can. It is more important that a paint roller pan be kept extremely level despite any sideward tilt or inclination of the ladder itself or of the holder. This is not as much of a problem with a paint can since a paint can is deeper than a paint roller pan and the paint can be kept at a lower level in the paint can. But, with a paint roller pan, since the pan is shallow and the paint must be kept closer to the top of the pan to provide a sufficient supply of paint in the pan, leveling of the pan while the pan is supported on the ladder is far more important.
Yet, known attachments or accessories for supporting paint roller pans on ladders do not take this into account or provide for easy leveling of the paint roller pan. They further do not do so on a bracket that is also designed and equally useful for holding paint cans. Thus, there is also a need in the art for a support bracket that may be quickly and easily attached to a ladder and that is equally useful for supporting either a paint can holder or a paint roller pan holder to one side of the ladder. Such a bracket and/or the paint roller pan holder ideally should be able to level the paint roller pan in a quick and easy manner.
One aspect of this invention relates to a support bracket for attachment to a side rail of a ladder and an object holding accessory for use with the support bracket. A U-shaped bracket has a pair of spaced side walls that include overlapping end walls at right angles to the side walls. The bracket is telescopically inserted around a side rail with the side walls of the bracket overlying inside and outside faces of the side rail and with the end walls overlying a front face of the side rail when the bracket is installed thereon. The end walls are adjustable relative to one another to vary the distance between the side walls to adjust the width of the bracket to accommodate ladder side rails having different widths. The side walls of the bracket are long enough to have extended wall portions thereon that extend past a rear face of the side rail of the ladder when the U-shaped bracket is telescopically installed around the side rail of the ladder with the side walls overlying the inside and outside faces of the side rail. At least one set of aligned holes is provided in the extended wall portions of the side walls. At least one object holding accessory is releasably coupled to the bracket for holding an object laterally outwardly of the outer face of the side rail. The object holding accessory includes a handle that is shaped to be received within the one set of aligned holes with the handle being longer than the distance between the side walls such that the handle extends completely through the bracket with a first end of the handle being located inwardly of an innermost side wall of the bracket.
Another aspect of this invention relates to a support bracket and a paint can holder and a paint roller pan holder for use therewith, the support bracket being attachable to a side rail of a ladder. The support bracket comprises a U-shaped bracket having an open end and an adjustable width. The bracket is telescopically inserted around a side rail of the ladder by pushing the bracket onto the side rail with the open end of the bracket receiving the side rail as the bracket is pushed onto the side rail. The side walls of the bracket having extended wall portions that stick out past the rear of the side rail. A paint can holder can be telescopically inserted through a set of aligned holes in the extended wall portions of the bracket to couple the paint can holder to the side rail of the ladder. A paint roller pan holder can also be telescopically inserted through a set of aligned holes in the extended wall portion to couple the paint roller pan holder to the side rail of the ladder. The paint roller pan holder includes a substantially horizontal pivot connection to allow a portion of the holder that supports a paint roller pan to be leveled relative to the horizontal.
Yet another aspect of this invention relates to a paint roller pan holder for use with a bracket carried on a side rail of a ladder. The paint roller pan holder comprises a handle adapted to be inserted through at least one hole in the bracket to couple the paint roller pan holder to the ladder. A support member is attached to the handle for supporting a paint roller pan. A substantially horizontal pivot connection is provided between the handle and the support member for allowing the support member to be leveled relative to the horizontal.
An additional aspect of this invention relates to a paint can holder for use with a bracket carried on a side rail of a ladder. The paint can holder comprises a handle adapted to be inserted through at least one hole in the bracket to couple the paint can holder to the ladder. A support member is attached to the handle for supporting a paint can. The handle is removably attached to the support member to be disposed in either an assembled, operative position or a non-operative, shipping or storage position. The handle in the operative position thereof extends outwardly away from the support member to be received within the hole in the bracket. The handle in the non-operative position thereof extends inwardly from the support member to be received within an open central area of the support member to reduce the size of the paint can holder for shipping or storage.
This invention will be described hereafter in the Detailed Description, taken in conjunction with the following drawings, in which like reference numerals refer to like elements or parts throughout.
A portion of a typical ladder 2 is shown in
Rungs 6 of ladder 2 can be solid as shown in
One embodiment of this invention comprises, in part, a support bracket 8 that can be easily installed around one ladder side rail 4. Bracket 8 can be used to support an object holding accessory from ladder 2. The object holding accessory can be a paint can holder 10 or a paint roller pan holder 11. A special paint roller pan to be described later is designed for use with paint roller pan holder 11.
Referring more particularly to
The lower edge of side wall 12 adjacent the inside face of side rail 4 is adapted to rest on top of or abut against a rung 6 of ladder 2, as shown in
Side wall 12 of bracket 8 is longer than side rail 4 so that side wall 12 has an extended wall portion 16 that sticks out beyond side rail 4 into free space behind side rail 4. Extended wall portion 16 of side wall 12 is simply whatever portion of side wall 12 that sticks out beyond side rail 4 when bracket 8 is installed on side rail 4. The length of extended wall portion 16 can vary, but typically comprises anywhere from 25% to 50% of the total length of side wall 12.
Overlapping end walls 14 of bracket 8 have horizontal slots 18 through which the threaded shank 19 of a fastener 20 extends. A wing nut 22 on the end of the threaded shank 19 can be tightened to clamp end walls 14 together in a horizontally adjusted position. Slots 18, fasteners 20, and wing nuts 22 allow the width of bracket 8, i.e. the distance between side walls 12, to be varied to accommodate side rails 4 having different widths. The width of bracket 8 will be set to slightly greater than the thickness of side rails 4. Once the width of bracket 8 is set for a particular ladder, it will not have to be readjusted. However, having a width adjustable bracket 8 allows the bracket 8 to be universal and to be used on a wide array of ladders with side rails 4 of different widths.
Extended wall portion 16 of side wall 12 is provided with three spaced attachment holes 24, 25 and 26. Each attachment hole 24, 25 and 26 preferably has a different shape. For example, as shown in
Referring now to
Handle 34 is long enough to extend all the way through bracket 8 with some room to spare. Thus, handle 34 extends between and is supported by both side walls 12. Handle 34 has threads or ridges 36 along an outer portion of its length and includes an enlarged head 38 at the outer end thereof. The enlarged head 38 is, however, smaller in diameter than the diameter of round holes 26 to allow handle 34 to pass through holes 36. The upward torque on the outer end of handle 34 arising from the weight of the paint can being supported on the opposite end will cause the outer end of handle 34 to slightly incline upwardly thereby causing ridges 36 to engage against the top of hole 26 on the inner side wall 12. In this orientation, the top of the enlarged head 38 will actually be raised higher than the top of hole 26 on the inner side wall 12. See
In the case of paint can holder 10, the holding cradle 32 is generally semi-circular or U-shaped having a base 40 and a pair of forwardly extending arms 42. Arms 42 have outer ends with notches 44 that are designed to fit up under the lugs 46 on either side of a paint can 48 that journal the bail 50. Lugs 46 on paint can 48 can carry enlarged washers 52 that overlie the outside of portions of notches 44. Washers 52 prevent lugs 46 from slipping out of notches 44.
Referring further to
Desirably, handle 34 attaches to base 40 of cradle 32 above the horizontal centerline of cradle 32. In other words, handle 34 is not symmetrically located on base 40, but is asymmetrically located towards the top of cradle 32. See
Turning now to
Paint roller pan holder 11 is able to level shelf 58 regardless of any side to side inclination of ladder 2 or handle 56. As shown in
The inner end of handle 56 has a U-shaped yoke 66 that includes circular end walls 68. Yoke 66 is designed to fit or nest around hub 62 with each end wall 68 of yoke 66 having an inner face adjacent one face of hub 62. The inner faces of end walls 68 carry a plurality of radial teeth or serrations 70 that mate with the teeth or serrations 64 on hub 62. A bolt 72 having a threaded outer end 73 and a wing nut 74 carried on outer end 73 adjustably lock the yoke 66 and hub 62 together.
Hub 62 and yoke 66 obviously form a horizontal pivotal adjustment that allows the angle between handle 56 and shelf 58 relative to the horizontal to be adjusted. For example, after handle 56 is inserted through holes 24, if handle 56 tilts or inclines relative to the horizontal as it extends to the side, this would mean that shelf 58 would be similarly tilted or inclined, giving rise to the possibility of spilling paint from paint roller pan 59 supported on shelf 58. To prevent this from happening, wing nut 74 can be loosened to free up the pivotal connection formed by bolt 72, and then shelf 58 can be pivoted upwardly as needed to reach a level orientation. Once shelf 58 has been leveled, wing nut 74 can be retightened to lock shelf 58 in place on handle 56 in its leveled orientation. Serrations 64 and 70 help serve as detents in this leveling orientation and further help to securely hold or lock shelf 58 in an adjusted position on handle 56. Serrations 64 and 70 could be deleted if desired.
Shelf 58 of paint roller pan holder 11 can have many forms for supporting and holding a paint roller pan thereon. However, preferably, shelf 58 is designed for use with a particular paint roller pan 59 so that the two positively mate and coact with one another to securely hold the paint roller pan 59 atop shelf 58. In this regard, shelf 58 is provided with a vertical, upwardly extending, tapered flange 76 having an L-shaped upper end 78. Flange 76 is set atop shelf 58 close to but to one side of wall 60. Each side of paint roller pan 59 is provided with an enlarged boss 79 that includes a downwardly facing pocket 80 that receives and fits down onto flange 76. The L-shaped upper end 78 of flange 76 is received relatively snugly within pocket 80 to help secure paint roller pan 59 to shelf 58. With this type of connection, shelf 58 need not be as large as the paint roller pan 59 itself and only partially underlies the bottom of paint roller pan 59.
The purpose of having two bosses 78 and two pockets 80, one of each on either side of paint roller pan 59, is to allow paint roller pan 59 to be installed atop shelf 58 in reversed orientations if so desired by the user. Thus, the paint containing well of paint roller pan 59 can be set either forwardly or rearwardly of side rail 4 depending upon the user's preference.
While preferred, the use of flange 76, bosses 79 and pockets 80 could be deleted. Shelf 58 could be enlarged and simply used as a base to underlie most if not all of a conventional paint roller pan. However, in this event, it would still be desirable to have some type of stop or latch to prevent the paint roller pan from being knocked or bumped off shelf 58. For example, shelf 58 could be a tray with raised sides into which a paint roller pan would be dropped in a nested configuration.
Bracket 8 is very easy to install on a side rail of a ladder simply by adjusting the width of bracket 8 to conform to the width of the side rail and then simply sliding bracket 8 around side rail 4. Bracket 8 will naturally assume an orientation in which serrations 13 on inner side wall 12 engage on a rung 6 of ladder 2 as shown in
Once bracket 8 is so installed, either paint can holder 10 or paint roller pan holder 11 can be inserted through appropriate sets of the aligned holes 24, 25 or 26. This can be simply and quickly done just by telescopic insertion of the handles 34 or 56 of holders 10 and 11, respectively. Handle 34 is designed to physically engage the top edge of the inner hole 26 to help keep paint can holder 10 in place. Similarly, handle 56 is inwardly tapered from its inner end to its outer free end to wedge itself into place in holes 24 to help keep paint roller pan holder 11 in place. If need be, the inclination of shelf 58 relative to handle 56 can be quickly and easily adjusted to allow shelf 58, and thus any paint roller pan 59 supported thereby, to be level. All in all, bracket 8 and holders 10 and 11 provide a versatile and adaptable system for allowing a user to support various paint receptacles and utensils adjacent a ladder.
Semi-circular holes 25 and round holes 26 are also desirably large enough to receive other accessories made by other manufacturers that normally slip into the interior of the rungs of ladders with hollow rungs. Most existing ladders with hollow rungs have either circular openings or semi-circular openings. Holes 25 and 26 are designed to mimic the shape of such openings to adapt bracket 8 for use with third party object holding accessories.
Various modifications of this invention will be apparent to those skilled in the art. For example, other accessory devices could be installed in holes 24, 25, and 26. For example, rather than supporting a paint roller pan 59, shelf 58 of holder 11 could be used to support a compartmentalized pan that holds various tools, such as wrenches, screwdrivers and the like. Thus, the scope of this invention is to be limited only by the appended claims.
