     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring specifically to FIG. 1, a tray 10 is illustrated in supported relation on the transmission and/or drive shaft tunnel or hump 12 in an automotive vehicle 14 in which the tunnel or hump extends longitudinally in the central area of the floorboard 16 and includes inclined side surfaces 18 which may be covered with a rubber floormat, carpeting or the like. The tray 10 includes a top surface 20 with compartments 22 therein for supporting various items such as beverages in containers, cigarettes, coins and the like. Also, the tray 10 includes a generally vertically disposed peripheral wall 24 having a lower edge 26 engaged with the tunnel or hump 12 in a conventional and well-known manner. The wall 24 usually defines a rectangular or square structure and the number of compartments as well as the shape and size of the compartments may vary. Each corner of the peripheral wall at the front and rear portions of the tray has an adjustable cleat 30 of the present invention mounted thereon with the cleats 30 engaging the inclined surfaces 18 to provide a stable support for the tray 10 in a manner set forth in more detail hereinafter. 
     As illustrated in FIG. 4, each cleat 30 includes an elongated arm 32 that tapers from a generally cylindrical mounting end 34 to a rounded outer end 36 with the side surfaces of the arm 32 tapering from a larger diameter end 34 towards a smaller radius outer end 36. One elongated side surface of the arm 32 is provided with a plurality of pointed projections 38 which form stabilizing points for gripping and adhering to various surfaces such as the rubber mat or carpet covering the inclined surface 18. The projections or points 38 are substantially conical in configuration and may vary in shape, size and spacing to provide adherence to the shape or texture of the supporting surface 18. The elongated central portion of the arm 32 is of reduced thickness as at 40 whereas the edge portion of the arm is of greater thickness for rigidity. 
     The cylindrical mounting end 34 of the arm 32 includes a serrated face 42 in which the serrations extend radially from a central aperture 44 with the ridges and valleys of the serrations extending radially so that the peripheral distance between the points on the ridges are circumferentially spaced a greater distance at their outer ends as compared to their inner ends. The arm 32 is preferably constructed of plastic material that can be moulded or otherwise constructed in a relatively inexpensive manner. 
     Each cleat 30 also includes a cylindrical mounting member 46 having a central aperture 48 therein with the diameter of the cylindrical mounting member 46 being substantially the same as the diameter of the cylindrical mounting end 34 on the arm 32 as illustrated in the drawings. The cylindrical mounting member 46 includes radial serrations 50 in which the ridges and valleys extend radially from the periphery of the central aperture 48 and are constructed to engage and interlock with the serrations 42 on the cylindridal end 34 on the arm 32. As illustrated in FIGS. 2 and 4, the central apertures 44 and 48 include a projecting cylindrical boss 52 on the cylindrical end 34 and a similar boss 54 on the cylindrical mounting member 46 with the ridged forming the serrations tapering radially from the outer edge of the respective bosses 52 and 54 for effective interlocking engagement when the mounting member 46 and the cylindrical mounting end 34 of the arm 32 are assembled and clamped together by a bolt 56 having a head 58 and a threaded portion 60 which receives a wing nut 62. The face of the cylindrical mounting member 46 opposite the surface having the boss 54 thereon is provided with a recess 64 shaped and sized to closely receive the polygonal head 58 of the bolt 56 to prevent the bolt 56 from rotating when the wing nut 62 is tightened and loosened. By tightening and loosening the wing nut 62, the angular position of the arm 32 in relation to the cylindrical mounting member 46 may be varied about the axis defined by the bolt 56 with the serrations serving to securely lock the arm in adjusted position when the wing nut 62 is tightened. 
     In order to mount the mounting member 46 on the end corner surfaces of the wall 28, an adhesive coating 66 is provided on the face of the cylindrical mounting member opposite the face having the serrations 50 thereon so that the adhesive coating 66 will adhere to the surface of the wall 24 in a secure manner as illustrated in FIG. 2. The adhesive surface is provided with a peel-off protective sheet 68 which protects the adhesive coating 66 in a well-known manner prior to the mounting member or attachment head 46 being mounted on the surface of the tray. 
     The structure of the adjustable cleats 30 enables them to be quickly and easily attached to the exterior surface of a hump mounted tray or any other tray or object desired to be supported in a stable and secure manner. By simply peeling off the protective cover for the adhesive, the mounting member or attachment head 46 may be securely and adhesively mounted on the surface of the tray or other object. This mounting procedure may be carried out with the cleat completely assembled with it only then being necessary to loosen the wing nut to enable the arm 32 to be adjusted to the desired position so that the projections or points 38 are engaged with the supporting surface after which the wing nut can be tightened. The projecting points 38 will effectively grip, adhere to and in some instances partially penetrate the supporting surface and will be effective to support a tray or other object on various surfaces including a rubber mat covering the floorboard area including the tunnel or hump, carpeted surfaces in an automotive vehicle, other carpeted surfaces such as floor surfaces and the like and also upholstered surfaces thereby enabling the adjustable cleats to be utilized effectively for many purposes in supporting various objects from various surfaces. The mounting member or attachment head may also be constructed of plastic material with the bolt and wing nut being of metal or also constructed of plastic material which will retain the costs of the adjustable cleats to a desired minimum. 
     The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and, accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
