Ladder tray

Abstract

A ladder tray has a tubular frame, a tray member and an adjustment bracket. The frame has an upper horizontal arm, a lower horizontal arm portion, a bridge portion connecting said upper and lower horizontal arms, and a support arm extending away from the bridge portion. A central portion of the tray is pivotally mounted to the upper horizontal arm portion. An adjustment bracket provides support and allows the tray to be secured to the ladder at different angled positions. The horizontal arms are received by adjacent hollow ladder rungs and a safety strap secures the tray to a side rail of the ladder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the figures, the ladder tray 10 of the present invention includes a tubular frame 20, a tray member 40, and adjustment bracket 60 and a safety strap 80. The tubular frame 20 is fabricated from the ¾ inch PVC piping components which are glued together in a manner well known in the art. The frame 20 includes an upper horizontal arm portion 22 which includes a first and 21 in the second end 23. The tubular frame and 20 also includes a lower horizontal arm portion 26 which includes a first and 25 and a second end 27.

A bridge portion 28 interconnects end 23 of horizontal arm 22 with end 27 of horizontal arm a 26. The bridge portion 28 includes a 90° elbow 29, straight pipe 30, 45° elbow 31, straight pipe 32, TEE 33, straight pipe 34 and a 45° elbow 35. The tubular frame 20 also includes a support arm a 36 which is formed by components TEE 33, straight pipe 37, and 45° elbow 38. Elbow 38 includes a threaded insert 39′ (such as a McMASTER.COM 93365A760) which is centered in an end cap for said elbow. A separate threaded knob 39 which has a flute head (such as a McMASTER.COM 93005A551) is provided. The threaded knob 39 passes through the groove 66 and, when fully tightened in to threaded insert 39′ secures the support arm 36 to the adjustment bracket 60 that a desired location along the length of the adjustment bracket 60. It will be obvious that my changing the location of the attachment will result in securing the tray 40 in any desired angled position. Users will often choose to secure the tray 40 in a horizontal position but the adjustment bracket 60 allows the tray to be secured at any desired angle. When the threaded knob 39 is fully tightened, the tray 40 will be securely held in a rigid position relative to the tubular frame 20.

The tray member 40 includes an upper surface 42, a lower surface 44, a first end 46, a second end 48 and a central portion 50. As shown in FIGS. 1-3, central portion 50 of tray member 40 is pivotally mounted the upper horizontal arm 22. As shown in FIG. 1 and FIG. 7, a pair of spaced apart frame support members 52 are mounted on the lower surface 44 of the tray 40. The support members 52 are provided with a generally U-shaped opening 53 (FIG. 7) sized to receive upper horizontal arm member 22. The tray member 40 preferably includes a plurality of openings 54 of various sizes and shapes adapted to receive and secure various objects onto the tray 40. For example, a variety of tools 130 such as screwdrivers, hammers and the like may be supported by said tray openings 54. This feature of the invention is best shown in FIGS. 3 and 4. Preferably, the tray member also includes a notch 56 which is adapted to receive a side rail 105 of ladder 100.

The adjustment bracket 60, as best shown in FIGS. 1, 5 and 8, includes a first end 62 which is pivotally mounted to second and 48 of tray member 40. The adjustment bracket 60 includes a second end 64 which extends longitudinally downward away from the tray 40. Adjustment bracket 60 includes a central groove 66 which is adapted to receive threaded knob 39.

A safety strap 80 consisting of two strips of Velcro material is utilized to secure the ladder tray 10 onto a side rail 105 of ladder 100. It will be obvious that various other types of belts or buckles or other strap, rope, chain or wire members could be utilized in place of Velcro straps. When in use, as shown in FIG. 4, end 21 of horizontal arm member 22 is inserted into the upper hollow rung 110 of ladder 100. Similarly, end 25 of horizontal arm member 26 is inserted in to the adjacent lower hollow rung 120 of ladder 100. The central portion 50 of tray 40 is pivotally supported by the upper horizontal arm member 22. The user may loosen the threaded knob 39 and tip the tray to any desired angled position and retighten the knob 39. The safety strap 80 is then securely tightened around side rail 105 of ladder 100.

The present invention provides an extremely economical and simple solution to a long-standing problem of providing a safe and secure location for necessary tools and supplies on a ladder. Because the present invention mounts a central portion 50 of the tray 40 over the upper horizontal or member 22, the tray 40 does not extend in to great a distance in front of or behind the ladder on which it is mounted. Such arrangement also keeps the center of mass of the tray 40 to the greatest extent possible supported directly over a ladder rail 105 so that little weight need be carried by the adjustment bracket 60. Because the fray member is fabricated from PVC piping components, the device is strong, light weight and may be easily and economically manufactured.

It is to be understood that while certain forms of the present invention have been illustrated and described herein, the present invention is not to be limited to the specific forms or arrangements of parts described and shown.
