     SUMMARY OF THE INVENTION 
     Although there are many devices currently available for supporting and restraining construction and roofing materials on a pitched roof, the present invention offers a lighter and more portable device for forefilling these objectives. The support of this invention is so constructed such that its contact surface is non-slidable with the surface of an inclined roof. The support is a solid body having a wedge-shaped structure with one of its surfaces adaptable for providing a non-skid contact with the surface of a sloping roof and at the same time providing another of its surfaces as a level support for a utility tray which may contain construction and roofing tools and/or materials. The support and tray are separable such that the support can be used independently from the tray or in conjunction therewith. The support is a solid body made from a non-skid material such as an elastomeric material and the tray can be made from various materials such as a light metal, plastic or hard rubber. The tray itself can have a handle for easier portability. 
     Each of the support and tray can be easily carried onto a pitched roof by a construction worker or roofer. The support is then positioned at a desired location on the inclined roof During the shingling of an inclined roof of a house or building, the support can be used as a restrainer for roof shingles or a bundle of roof shingles by coming in contact with one of its inclined surfaces. By such an arrangement, the shingles or bundle of shingles are restrained by the support from sliding down the inclined surface of the roof The support can also be used to restrain other construction materials such as lumber and small building units. If desired, the tray can be placed on the level surface of the support to contain construction tools and/or materials while the construction worker or roofer is working on the inclined or pitched roof 
     Thus, it is an object of this invention to provide a lightweight and portable support on a pitched or inclined roof for holding or restraining construction materials and prevent them from sliding down or off the pitched or inclined roof of a house or building. 
     It is another object of this invention to provide a tray which can be used in conjunction with the support for holding or containing construction or roofing tools and/or materials therein. 
     Other objects and advantages of the use of the support and tray of this invention will become apparent upon reading the following description, of which the attached drawing form a part.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to FIG. 1, there is shown one example of the use of the support of this invention. The support 10 is located on the inclined surface 35 of a roof 30. The support 10 is holding or restraining a bundle 40 of roofing shingles by a leading edge of the support 10. Although the bundle 40 of roofing shingles is shown being restrained on its broad side, it may also be restrained on its end side. On a top level surface of the support 10 is positioned a tray 20 which is secured to the support 10 by overlapping side extensions on the underside of the tray 20. When the tray 20 is not used, a number or a bundle of shingles may be supported in whole or in part on the level surface of the support 10. Alternatively, the support 10 can also be used to restrain or hold other construction articles such as lumber, building units, etc. 
     In FIGS. 2 and 3, there are shown two different perspective views of the support 10. The support 10 is a solid body having a wedge shape. The solid body forms a polyhedron. The support 10 has a flat bottom contact surface 11, a pair of parallel identical surfaces 12 (only one of which is visible) extending perpendicularly from opposite sides of the contact surface 11, and three flat, inclined surfaces 13, 14, and 15 extending between the pair of parallel surfaces 12. The three flat surfaces 13, 14, and 15 together with the bottom contact surface 11 and the pair of parallel surfaces 12 form the outer boundaries of the support 10. Flat surface 14 of the support 10 is the surface where the tray 20 is positioned and secured when it is desired to use it. The flat surface 14 can also support construction and roofing tools or materials when the tray is not used. The support 10 is constructed from an elastomeric material which is non-skid with most roof surfaces. An elastomeric material which has been found to be quite effective is foam rubber. Foam rubber is also a lightweight material making the support 10 easily portable by a construction worker or roofer. The dimensions for the support 10 may vary depending on the application required. However, the following dimensions for the support 10 of this invention have been found to be quite practical for many of the applications performed by a construction worker or roofer working on an inclined or pitched roof The contact surface 11 is approximately 34&#34;×12&#34;, the inclined surface 13 is approximately 4 and 1/2&#34;×12&#34;, the inclined surface 14 is approximately 23&#34;×12&#34;, and the inclined surface 15 is approximately 24 and 1/2&#34;×12&#34;. The perpendicular height from the base 11 to the crest 16 is approximately 19&#34;. The angle between the base 11 and the inclined surface 15 is approximately 50 degrees, the angle between the inclined surface 14 and the inclined surface 15 is approximately 90 degrees, the angle between the inclined surface 14 and the inclined surface 13 is approximately 135 degrees and the angle between the base 11 and the inclined surface 13 is approximately 85 degrees. The latter angle between the base 11 and the inclined surface 13 is maintained large so that there is less likelihood for the edge 17 to break off with continued use of the support 10 and so that the surface area 13 can better support or restrain various construction articles of different shapes and sizes. The support 10 which is fabricated from foam rubber may be computerized laser cut or molded. Alternatively, the support 10 may be fabricated from other non-skid elastomeric materials. 
     Referring now to FIGS. 4 and 5, the tray 20 has a base 22 with a handle 21 attached at the center of the base 22. The tray is approximately 12&#34; wide and 22&#34; long. The tray 20 has four sides 23, 24, 25, and 26. Each of the sides 23, 24, and 25 is approximately 4&#34; in height with the base 22 being set therein about 2 and 1/2&#34; thus providing about 1 and 1/2&#34; overhang to extend over three sides of the support 10. The side 26 of the tray 10 is 2 and 1/2&#34; in height with no overhang or extension. The dimensions of the tray 20 given here are adaptable to the support 10 with the dimensions of the support 10 given in the example above but may have different dimensions to accommodate a different sized support 10. When the tray 20 is used on an inclined or pitched roof, it is set over the flat surface 14 with the overhang extensions providing a fit contact with the parallel sides 12 and the inclined surface 15 of the support 10 to adequately hold or secure the tray 20 to the support 10. The tray 10 may be constructed from lightweight sheet metal, hard rubber or heavy gauge plastic. If the tray 10 is made from sheet metal, the sections thereof may be soldered together. If the tray 10 is made from hard rubber or plastic, the hard rubber or plastic may be molded into the desired shape of the tray 10. 
     Another use of the wedge-shaped support 10 of this invention is to use two of the supports in a scaffold on an inclined roof. For example, two of the supports 10, 10 are set on an inclined roof at a laterally spaced position from each other and a board or boards are placed onto the level surfaces 14, 14 of the respective supports 10, 10 such that they straddle the space between the two supports 10, 10. The scaffold thus produced is capable of supporting various construction or roofing articles. 
     Modifications of this invention will be readily apparent to those skilled in the art and it is intended that the invention be not limited by the embodiments disclosed herein but that the scope of the invention be defined by the appended claims.
A support for holding or restraining construction or roofing articles on an inclined or pitched roof. The support prevents construction or roofing articles from sliding down or off the inclined or pitched roof of a house or building and allows the construction worker or roofer to position the articles in the immediate area where the construction worker or roofer is working. The support may also have a tray attached to a level surface of the support so that construction tools and/or materials may be located therein for ready accessibility to the construction worker or roofer.
