A spreader bar is provided to engage the upper portion of the stiles or the underside of the top step of the ladder, and apply pressure via first and second threaded members to the upper portion of the surface mounted about the ladder, the threaded members having foot pads formed to apply downward pressure so as to anchor and stabilize the support surface.
Description
- None.
- No funds were provided by the Federal Government for research or development of the present invention.
- The present invention relates to horizontally situated, planar support surfaces, and in particular to a portable tray, table or shelf support surface formed to readily engage the upper portion of a stepladder or the like.
- A stepladder is generally formed of front and rear sets of stiles hingedly attached to a top step so as to, when opened, form a generally inverted “V” configuration, with the front set of stiles having a series of evenly spaced rungs or steps mounted thereto for use as steps by the user. Pivotal stays are provided generally medially between the front and rear stiles to retain the opened ladder in an open position.
- Stepladders are a necessary tool for many craftsman such as painters, carpenters or the like. During such operations, there often exists a need to have on hand, while on the ladder, a variety of materials, tools, and or implements. The prior art has contemplated various brackets and support surfaces which may engage the ladder to provide to the user a means of readily supporting, mounting, or holding the necessary item(s).
- However, these types of devices are believed to suffer from various shortcomings. Many of the devices fail to provide a truly stable support surface, while others are very specialized in the type of items being supported. Still other devices are only made for certain types of operations, or require a custom configured ladder in order to work.
- It is therefore believed that the prior art has failed to contemplate a table or shelf-type horizontal support system which readily mounts to a standard step ladder and provides a stable and generally reliable support.
- The preferred embodiment of the present invention contemplates a support surface which is generally rectilinear in configuration, and has an opening formed generally medially therethrough for receiving the upper portion of the stepladder. A receiver is formed generally through the support surface at the opening, the receiver having walls emanating from the underside of the support surface, the walls having an interior surface formed at an angle commensurate with the angle of the exterior edges of the front and rear stiles forming the open stepladder, so that the inner sidewalls of the receiver directly engage and are supported by said stiles.
- To stabilize the support surface, an expansion clamp, spreader bar, or the like is provided to engage the underside of the upper portion of the stiles and/or the underside of the top step of the latter, said spreader bar having first and second ends having laterally emanating therefrom first and second threaded members formed to have an adjustable length to engage the upper portion of the surface mounted about the ladder, the threaded members having foot pads formed to apply pressure upon the support surface, so as to anchor and stabilize same.
- The present invention thereby provides a table or shelf-type horizontal support system which readily mounts to a standard step ladder, while and providing a more stable and reliable support than prior art systems.
- For a further understanding of the nature and objects of the present invention, reference should be had to the following detailed description, taken in conjunction with the accompanying drawings, in which like parts are given like reference numerals, and wherein:
-

FIG. 7 is a side, close-up view of the spreader bar situated between the stiles in the vicinity to the top step of the ladder, or the underside of the top step, and the upper surface of the support surface. - The planar support S of the present invention is particularly suitable for such activities as painting, including detailed painting procedures such as faux painting or the like, and has been referred to as a “faux caddy”.
- Referring to
FIGS. 1-6 The planar support S is installed upon a standard, off-the-shelf step ladder L (such as that illustrated inFIG. 3 ), the ladder having front 1, 1′ and rear 3, 3′ sets of stiles, each of the stiles having top 2 and bottom 2′ ends, the front 1, 1′ stiles situated in parallel arrangement relative each other (having a uniform width 4 therebetween), as are the rear 3, 3′ stiles, the front stiles having evenly spaced stairs or rungs 5, 5′ situated therebetween. The top 2 of each of the sets 1, 1′ and 3, 3′ of stiles are hingedly 7, 7′ affixed to opposing ends of atop step 6 having anunderside 6′ so that the stiles can be selectively pivotally opened 8 for use, or closed for storage. When fully pivoted to the open position, the opposing front and rear stiles are held in position via pivotable stays 9 situated therebetween. - The
support surface 10 which forms a table or shelf-like support surface has first 11 and second 11′ edges andfront 12 and rear 12′ ends (which may be raised as shown to prevent spillage), atopside 13 and anunderside 13′, shown in an exemplary rectilinear configuration. Generally medially situated from a lengthwise perspective (and near thefront 12 end depthwise) is an opening 15 formed therethrough having awidth 13 anddepth 14′ for receiving the upper portion of the step ladder. - Emanating from the
underside 13′ of thesupport surface 10, about the opening 15, are front 16 and rear 16′ angled receiverwalls having angles side receiver walls front receiver wall 16 and rear 16′ receiver walls are situated adjacent to and engage at theirinner sides - For example, if the stiles of the ladder, when opened, extend at an 11 degree angle with regard to the vertical, ideally the
angled receiver walls top step 6 protrudes through opening 15 and saidwalls FIG. 1 . As shown, the unit is installed upon the ladder such that thefront end 12 is associated with the front stiles 1, 1′, so as to provide the most maneuverability and safety during use, with the main planar support areas to the side and opposing end of the ladder from the steps. The opening is shown as having a rectilinear configuration, but may vary with the configuration of the ladder used therewith. - Continuing with
FIGS. 1 , 3, and 4-7, aspreader bar 21 is utilized to anchor the unit in place. Once the tray unit or planar support S is in place upon the ladder, aspreader bar 21 having first 22 and second 22′ ends, each end having anaperture underside 6′ of thetop step 6 of the stepladder, and thetop 13 of thesupport surface 10. Thespreader bar 21 has first 24 and second 24′ bolts formed to engage threaded nuts 45, 45′ aligned withapertures support surface 10. It is noted that the footers may include rubber grommets, or be rubberized, to prevent marring of the support surface. It is also noted that, in lieu ofbolts apertures - In use, once placed between the top step of the stepladder and the support surface of the planar support as shown, the bolt head is rotated 27 so that the treads 28 in each bolt engage their
respective bolt support surface 10, the spreader bar engaging the upper portion of the stiles (or the underside of the top step of the step ladder, depending upon the ladder design, applying pressure 30 to the spreader bar and anchoring the receiver of the planar support firmly against the stiles of the ladder, so as to stabilize the support system S upon the ladder. - The present system thereby provides a horizontally situated planar support, which can be in the form of a caddy, table, tray, or shelf-like support system for an off-the-shelf stepladder which is easy to install, relatively inexpensive to fabricate, and stable in operation.
