United States Patent 3,229,943 PAINT BUCKET HOLDER FOR EXTENSION LADDERS Lawrence H. Olson, Silver Lake, Kans. Filed Nov. 9, 1964, Ser. No. 409,665 8 Claims. (Cl. 248-210) This invention relates to bucket retaining and supporting structure, and more particularly, to a holder for a paint bucket for use with a generally upright, inclined extension ladder.

It is the primary object of the present invention to provide a paint bucket holder for use with an extension ladder wherein the holder is rugged in construction, economical to produce, can be positioned on a ladder at a location convenient to the user without interfering with the stance of the user on the ladder, and which is capable of being readily moved into any one of a number of operative positions along the ladder, all to the end that the bucket holder provides an improved structure for eliminating the cumbersome means which have heretofore been used to accomplish this purpose.

Another object of this invention is the provision of a bucket holder of the type described which utilizes the weight of a bucket thereon to hold the same in place on a ladder, whereby the construction of the holder is simplified inasmuch as additional fastening devices are not required to maintain the same in place on a ladder.

A further object of the instant invention is the provision of a bucket holder of the aforesaid character having a bucket-supporting platform which can be pivoted through a relatively wide range of angles, whereby the platform can be adjusted as the inclination of a ladder associated therewith is changed so as to prevent the tipping of a bucket on the platform.

In the drawing:

FIGURE 1 is a front elevational view of the bucket holder in an operative position on an extension ladder;

FIG. 2 is a side elevational view of the bucket holder on the ladder;

FIG. 3 is a view similar to FIG. 2 but looking in the opposite direction, parts of the holder being broken away to illustrate details of construction; and

FIG.'4 is a top plan view of the holder removed from the ladder.

The present invention provides a paint bucket holder for an extension ladder and includes a rigid panel secured at the normally uppermost edge thereof by a pair of hinges to the underside of a bucket-supporting platform to permit movement of the ladder about a generally horizontal axis when the panel is in an operative position on the side of an extension ladder. A link pivotally secured at one end thereof to the underside of the platform in spaced relationship to the hinges extends downwardly from the platform and is disposed adjacent to the proximal face of the panel. A screw carried by the panel extends through an elongated slot in the lower end of the link and a nut releasably secures the link to the screw, and thereby the panel to maintain the platform horizontal.

A channel at one side of the panel is normally fitted over a side rail of an extension ladder, and a strap hav ing projections at the ends thereof is secured to and extends along the outer longitudinal edge of the channel. The lower projection on the strap cooperates with a lower, inclined edge of the channel to present a rungreceiving notch. The upper projection merely engages a rung when the adjacent lower rung is received within the notch. The platform is disposed'with respect-to the notch such that the weight of the bucket on the plat- 3,229,943 Patented Jan. 18, .1966

rung and maintains the bucket holder in place. This feature of the bucket holder eliminates the need for additional fastening structure.

Bucket holder 10 includes a generally rigid support member or panel 12 having a normally uppermost edge 14 to which a pair of spaced hinges 16 are secured. The underside of a bucket-supporting platform 18 is also secured to hinges 16 to permit pivotal movement of platform 18 about a generally horizontal axis when panel 12 is in an inclined, operative position described hereinafter.

The configuration of platform 18 is shown in FIG. 4; however, it is to be understood that platform 18 may be of any configuration. However, it is to be preferred that hinges 16 engage the underside of platform 18 within the periphery thereof so that the major portion of platform 18 overlies at least the central area of panel 12 when the latter is in the inclined, operative position thereof shown in FIG. 3. A continuous rim 20 is secured to and extends upwardly from the periphery of platform 18 to prevent the lateral movement of a bucket 22 off platform 18. v

A link 24 is pivotally secured by a hinge 26 to the underside of platform 18 in spaced relationship to hinges 16. Link 24 extends downwardly and has a section 28 angularly disposed relative to the major portion thereof which extends downwardly from platform 18. Section 28 is normally in juxtaposition with the proximal face of panel 12 and has a longitudinally extending slot 30 therein which receives a screw 32 carried by and extending outwardly from panel 12. A wing nut 34 carried on the outer end of screw 32 is engageable with section 28 to clamp the latter against panel 12 to releasably maintain platform 18 in a fixed disposition relative to panel 12. a An elongated, transversely C-shaped' channel 36 is rigid to and extends along one side of panel 12 as shown in FIGS. 1 and 4. For purposes of illustration, channel 36 is shown as being integral with panel 12, but it is to be understood that these two components could initially be separate and subsequently rigidly interconnected in any suitable manner. Channel 36 is substantially equal to the length of the corresponding side of panel 12 and has anouter, longitudinally extending side wall 38 provided with a lower, outer edge segment 40 which is inclined with respect to the major portion of the outer, longitudinal edge of side wall 38.

A longitudinally extending flange 42 is integral with the aforesaid major portion of the outer, longitudinal edge of side wall 38 to which a strap 44 is securedby bolt means 46. Strap 44 extends longitudinally with flange 42 and has a normally upper, arcuate projection 48 extending outwardly from the proximal extremity of channel 36 as shown in FIGS. 1 and 2. Strap 44 also has a lower, straight projection 50 which is disposed at an angle with'respect to the longitudinal axis of strap 44 and is adjacent to segment 40. Projection 50 converges with respect to segment 40 as flange 42 is approached to present, with segment 40, a notch 52 at the lower extremity of channel 36. It is to be noted that the distance between projection 48 and notch 52 is substantially equal to the distance between a pair of adl a size and configuration to be disposed over one of the form biases the upper projection against the proximal rails 58 and is movable therealong when channel 36 is tilted slightly so that flange 42 does not engage a rung 54 so as to prevent movement of channel 36 with respect to, ladder 56. l

- In use, ladder 56 is initially placed in its operative, nor- 3 mally inclined disposition such that rungs 54 are vertically spaced and rails 58 are inclined with respect to the vertical. Holder is mounted on ladder 56 by first carrying holder 10 to the proper height on ladder 56 and lowering holder '10 so that the proximal runk 54 is received within notch 52, and the lower portion of channel 36 is disposed over the proximal rail 58.

The rung 54 in notch 52 engages segment 40 and, projection 50 to permit forward pivotal movement of channel 36 and thereby panel 12, until projection 48 engages rungs 54. For purposes of illustration, projection 48 complementally engages the proximal rung 54, although it is understood that this construction of projection 48 is unnecessary. As projection 48 moves toward the proximal rung 54 the remaining portion of channel 36 moves onto rail 58 so that, when projection 48 engages the proximal rung 54, channel 36 is disposed on rail 58 in the manner illustrated in FIGS. 2 and 3.

Thus, platform 18 can be adjusted so that it is horizontal. To accomplish this, wing nut 34 is moved away from section 28 to permit the latter to move with respect to panel 12 until platform 18 has assumed a horizontal disposition. Thereupon, Wing nut 34 is moved toward and in frictional engagement with section 28 to clamp the latter to panel 12 thus releasably mantaining platform 18 in a fixed position with respect thereto. Holder 10 is then ready to support bucket 22.

The angular disposition of platform 18 with respect to panel 12 can be changed by manipulating wing nut 34 and moving section 28 until platform 18 is once again horizontal. is on platform 18 if the change in the inclination of ladder 56 is small and there would be no tipping of the contents of bucket 22 as a result.

When bucket 22 is on platform 18, the line of action of the weight of the bucket and its contents will, by virtue of the specific placement of platform 18 on panel 12, extend downwardly at least between the pair of adjacent This can be accomplished while a bucket 22 rungs 54 to which holder 10 is coupled. The weight of A bucket 22 and its contents will, therefore, bias holder 10 in a counterclockwise direction when viewing FIG. 2 so that projection 48 will be biased toward the proximal rung 54. This feature of holder 10 obviates additional structure for fastening holder 10 to ladder 56. Moreover, holder 10 is constructed so that the weight of a bucket and its contents on platform 18 will always be forwardly of the lower rung 54 for all normal operative positions of ladder 56.

' Holder 10 can be used to support any kind of object which can be placed on platform 18 and is not to be limited to the use of paint buckets alone. Platform 18 could conceivably be used to support tools, cleaning materials, brushes, and other articles which are presently carried on the person or which must be supported by conventional methods on an extension ladder.

Channel 36 mounts panel 12 so that the latter projects to the side of the corresponding rail 58. In this location, panel 12 supports platform 18 so that a workman on ladder 56 may conveniently use bucket 22 or other articles on platform 18 without having to move his body in order to have access to the materials on platform 18.

As illustrated, holder 10 is constructedfor use by a righthanded workman; however, it is understood that holder 10 could also be constructed sothat thesame is disposed on the left-hand side of ladder 56. In this respect, channel 36 would be secured to the oppositeside of panel 12 and the outer side wall of channel 36 would have flange 42 and strap 44 thereon. Means could be provided to change channel 36 from one side of the panel to the other, and strap 44 could be constructed to provide securing means for holder 10 regardless of which side channel 36 was on.

The width of channel 36 can be different from that shown to accommodate holder 10 for ladders having rails of another thickness, such as aluminum ladders now available.
