Adjustable Slide-on shelf for railings or other vertical surfaces for setting things on or attaching things to

Abstract

An adjustable Slide-On Shelf for railings or other vertical surfaces for setting things on or attaching things to. The shelf has adjustable vertical boards attached lengthwise to it. The vertical boards attached to the bottom of the shelf can be slid closer together and further apart so they can be slid over a railing and slid together and tightened to make the shelf stable. It has removable foam strips that attach easily with no tools to the inside of the adjustable vertical boards. This allows it to fit snugly against railings such as wrought iron railings with rails different in size from the slats. This makes the unit universally fit different sized and shaped railings or other narrow vertical surfaces. Attachments such as storage boxes can be added to the top of the shelf.

         14 . I claim a detachable shelf to be slid onto narrow vertical surfaces, creating a flat surface to sit things on, on top of the narrow vertical surface it is slid onto; the shelf being comprised of a flat surface with enough width, length and thickness to form a horizontal flat surface on the narrow vertical surface it is slid onto, with 2 flat surfaces with some length, width and thickness attached vertically and lengthwise to the bottom of it using a bracket system that is adjustable to allow the vertical flat surfaces to be slid apart and closer together thus forming an adjustable sized gap between the flat portions of the vertical surfaces, with a strip made of a pliable material that can be attached and removed quickly and easily to and from the insides of the 2 vertical boards, thus allowing the shelf to be slid onto different sized and shaped narrow vertical surfaces and secured to them. 
     
     
         15 . The horizontal surface on the shelf of  claim 14  can have surfaces with some width, length, and thickness attached to it's sides to form a lip around the edges of the horizontal surface. 
     
     
         16 . The horizontal surface on the shelf of  claim 14  can have items such as a storage box attached to the top of it. 
     
     
         17 . The adjustable bracket system on the device in  claim 14  consists of 4 bolts that extend from the bottom of the horizontal surface and a narrow block with holes that slide over the bolts and are secured by screwing nuts onto the bolts. 
     
     
         18 . The vertical boards set forth in  claim 14  have extensions on the bottom edge of them that are placed under the block defined in  claim 17  above, which attaches the vertical surfaces to the flat horizontal surface when the nuts are put in place onto the bolts and over the blocks, with the nuts being left loose to allow the vertical boards to be adjusted either closer together or further apart, and tightened to secure the vertical boards into place, therefore securing the shelf in  claim 14  to the narrow vertical surface they have been slid onto. 
     
     
         19 . The flat vertical surfaces that are attached to the horizontal flat surface as set forth in  claim 14  have a quick attaching and removing system such as Velcro attached to the inside flat portions of each of the vertical surfaces. 
     
     
         20 . Strips can be attached to the quick attaching and removing system on the insides of the vertical boards as set forth in  claim 19 , the strips having the same quick attaching and removing system as the vertical boards. 
     
     
         21 . The strips set forth in  claim 20  are made of a pliable material such as rubber foam that have enough flexibility to compress when pressed against the vertical sides of the narrow vertical surface it is being slid onto, and to form indents in the pliable material if the pliable material is pressed against an uneven or inconsistent surface such as a surface with slats, with the pliable material being thick enough to press against an indented area if the narrow vertical surface the shelf is being slid onto has a wider top section with a narrower indented area below the wider top section. 
     
     
         22 . An alternative bracket system such as a channel system that allows the flat vertical surfaces to be attached to the horizontal flat surface and where the vertical boards can be slid closer together and further apart forming a variable sized gap between the vertical surfaces can be used instead of the bracket system set forth in  claim 17 , therefore eliminating the need for the extensions at the bottom of the vertical surfaces as set out in  claim 18  if this alternative bracket system is used.
