Abstract
TRAY ATTACHMENT FOR ALADDER
ABSTRACT OF THE DISCLOSURE
There is provided an auxiliary tray for ladders which have hollow rungs opening through both runners. The auxiliary tray includes a flat pan, a shaft projecting from one end of the pan and rigidly affixed thereto, a tubular member into which the shaft can be inserted, means to fix the relative angular position of the shaft with respect to the tubular member, and a bracing member extending away from the tubular member and having an elongated portion parallel with the tubular member. The elongated portion is adapted to enter one of the hollow rungs as the tubular member enters another.
ABSTRACT OF THE DISCLOSURE
There is provided an auxiliary tray for ladders which have hollow rungs opening through both runners. The auxiliary tray includes a flat pan, a shaft projecting from one end of the pan and rigidly affixed thereto, a tubular member into which the shaft can be inserted, means to fix the relative angular position of the shaft with respect to the tubular member, and a bracing member extending away from the tubular member and having an elongated portion parallel with the tubular member. The elongated portion is adapted to enter one of the hollow rungs as the tubular member enters another.
Description
~Z~399~3 This invention relates to an auxiliary item for use with ladders of the kind having hollow transverse rungs between the longitudinal runner members. The hollow transverse rungs open through both of the runner mel~ers, sùch that it is possible to pass an elongated rod or the like directly through the rung of the ladder from one side to the other. The auxiliary item to which this invention particularly relates is a tray adapted to be affixed to the ladder, and to permit the user to place thereon such things as paint cans, roller trays, and the like.
It is an aspect of this invention to provide an auxiliary tray for ladders, which is simple to utilize and to place in position, adjustable in order to accommodate different ladder angles, and of inexpensive construction.
Accordingly, this invention provides, for use with a ladder having spaced longitudinal members and hollow transverse rungs opening through both longitudinal members, an auxiliary tray which comprises:
a flat pan, a shaft rigidly affixed with respect to the pan and projecting from one edge of the pan, a tubular member into one end of which the shaft is insertable, the tubular member being adapted to extend through a hollow rung of the ladder, means on said one end of the tubular member for restraining relative rotation between the shaft and the tubular mer~er, and a bracing member affixed to the tubular member adjacent said one end and including an elongated portion which is parallel with the tubular member and spaced there-1289~23 from, the elongated portion being adapted to enter one hollow run~ of the ladder as the tubular member enters another hollow rung.
One embodiment of this invention is illustrated in the accompanying drawings, in which like numerals denote like parts throughout the several views, and in which:
Figure 1 is a perspective view of a tray embody-ing this invention, showing in broken lines a ladder with whlch the tray is utilized;
Figure 2 is a further perspective view of the tray of Figure 1, seen from underneath; and Figure 3 is a sectional view taken on the line 3-3 in Figure 1.
In Figure 1 a tray 10 is seen to include a flat pan `12 which is generally of rectangular configuration and has upstanding marginal edges 14. A shaft 16 has a portion 18 extending along the underside of the pan 12 as can be seen in Figure 2, the portion 18 being aligned along the right bisector of two of the opposed parallel edges of the pan 12. Thus, the pan 12 extends to either side of the shaft 16. The shaft also includes a projecting portion extending away from the pan 12, and adapted to be received within one end of a tubular member 22, the ladder being long enough to extend through a hollow rung 23 of the ladder 25 shown in broken lines in Figure 1. As can be seen in Figure 1, the ladder is of the well-known type, usually of aluminum alloy, in which the transverse rungs 23, 23', etc., are hollow and open out through the longitudinal runner members 28.
The projecting portion 20 of the shaft 16 is adapted to be received within one end of the tubular member 22, as f~>~
`` 1'~89''3;~
can be seen in all of the figures, and particularly in Figure 3. Means are provided on the end of the tubular member into which the projecting portion 20 of the shaft 16 is inserted, for locking the shaft 16 and the tubular member together against relative rotation and against relative longitudinal movement. As can be seen in the figures, this means includes a threaded locking screw 30 which engages an internally threaded upward projection 32 on the tubular member 22.
A bràcing member shown generally by the numeral 34 in Figure 2 is affixed to the tubular member 22 adja-cent the end into which the shaft 16 is inserted. As can be seen in the figures, the bracing member includes a briding member 36 extending substantially perpendicularly away from the tubular member 22, and affixed thereto closely adjacent the end into which the shaft 16 is inserted, andan elongated portion 38 which is disposed parallel with the tubular member 22 and is arranged so that it can enter another one of the hollow rungs of the ladder. In the embodiment shown, the distance between the elongated portion 38 and the tubular member 22 is the same as the distance separating two adjacent rungs 23 and 23' of the ladder, such that these two members are insertable into adjacent rungs as shown.
As can be seen in Figure 1, the tubular member 22 has, at its end opposite the end into which the shaft 16 is inserted, means for selectively preventing withdrawal of the tubular member through the hollow ladder rung 23.
Specifically, the means inGludes a plurality of perforations 41 at longitudinally spaced positions, the perforations 41 ``` i~8!~3 being adapted to receive a cotter pin 42. Several of the perforations 41 are provided, in order to accommodate ladders of differing widths.
The shaft 16 is illustrated as bein~ affixed to the pan 12 by fastening members 44, although it will be appreciated that other means of affixing the shaft with respect to the pan could be utilized. The important aspect of the structure is the fact that the shaft extends out-wardly from the pan and is rigidly affixed with respect thereto.
It will also be understood that it would be con-ceivable to make the spacing between the elongated portion 38 and the tubular member 22 the equivalent of two or more rung spacings, although this would make the size of the auxiiiary tray more unwieldy than necessary.
