[0033] While various embodiments are amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the claimed inventions to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter as defined by the claims.
DETAILED DESCRIPTION OF THE DRAWINGS
[0034] Attached are drawings of an embodiment of the deep ladder tray of the present invention incorporated into a stepladder in an in-use orientation (
[0035] The following detailed description should be read with reference to the drawings in which similar elements in different drawings are numbered the same. The accompanying figures depict embodiments of the electro-mechanical brake system of the present invention, and features and components thereof. Any references to front and back, right and left, top and bottom, upper and lower, and horizontal and vertical are intended for convenience of description, not to limit the present invention or its components to any one positional or spatial orientation. The drawings, which are not necessarily to scale, depict illustrative embodiments and are also not intended to limit the scope of the invention. Any reference in the claims to a “stepladder” is not intended to limit the scope of the invention to a specific type of climbing device and includes ladders, step stools, etc.
[0036] A stepladder according to an embodiment of the invention is depicted in
[0037] Stepladder 100 may also have one or more platforms 140 to provide a more secure standing area when stepladder 100 is in use. Platforms 140 for stepladders 100 are typically folding and rely upon links to move the platform 140 from a stored configuration to an in-use configuration. Stepladders 100 also commonly have a foot 170 on the end of the front rails 110 and rear rails 120 to protect surfaces onto which the stepladder 100 is placed and to provide a wider footprint and better traction for the stepladder 100.
[0038] In one embodiment, a folding tray 200 is attached to the stepladder 100. In the embodiment depicted in
[0039] Tray 200 has a height dimension 290 that represents the outermost dimension of the tray 200 between the exterior of the front wall 220 and exterior of the rear wall 230 in a front-to-back direction, a width dimension 280 that represents the outermost dimension of the tray 200 between exterior of the shoulders 245, and a depth dimension 270 that represents the outermost dimension of the tray 200 in a direction between the top surface 205 and exterior of the bottom surface 215. The combination of these dimensions 270, 280, 290 define the outer boundary of the tray 200. Tray 200 also has a tray width boundary 285, which represents the outermost dimension of the tray 200 between the exterior of the side walls 240. The stepladder 100 also includes a platform gap dimension 115, which represents the distance between the upper edge of the platform 140 and the bottom edge of the top cap 145 when the stepladder 100 is in the stored orientation (
[0040] In the embodiment depicted in
[0041] To facilitate storage of the tray 200 when not in use and to increase the amount of storage space provided an embodiment of the tray 200 fits within the boundaries of the stepladder 100 when the stepladder 100 is in the closed or stored orientation. In this embodiment, the tray height dimension 270 is less than the step gap dimension 115, the tray width dimension 280 is less than the stepladder rail interior width dimension 135 at the location where the tray 200 is in its stored orientation (
[0042] Various embodiments of systems, devices, and methods have been described herein. These embodiments are given only by way of example and are not intended to limit the scope of the claimed inventions.
