Mounting bracket assembly
BACKGROUND OF THE INVENTION 
     This invention relates in general to mounting bracket assemblies and, in particular, to an assembly adapted to be secured either to a flat planar surface or to an arcuate surface and to support an appliance such as a radio, for example. 
     DESCRIPTION OF THE PRIOR ART 
     There are a number of mounting brackets known in the prior art and specifically adapted to mount radios or similar appliances to various surfaces. 
     Some of these such as, for example, Van Ordt U.S. Pat. No. 3,658,219, are capable of adjustment in one direction, but none known to applicant are capable of adjustment in a plurality of directions as is the case with the invention herein. Such adjustment is considered desirable to enable the user of the radio to enjoy the most efficient and comfortable use thereof. 
     Furthermore, these devices are normally designed to be mounted in a vehicle, and many have a built-in curved or arcuate base suitable for mounting on the hump caused by the drive shaft of the vehicle. An example of this type device may be seen in Hanley, U.S. Pat. No. 3,550,001. However, because of this feature, they are not flexible in that considerable difficulty would be encountered in mounting such a device on a flat planar surface such as the wall of a camper or other vehicle, for example. 
     BRIEF SUMMARY OF THE INVENTION 
     It has been found that the above-noted disadvantages can be overcome by providing a mounting bracket assembly capable of being mounted on either flat planar or arcuate surfaces and capable of being adjusted in a variety of directions. 
     It has been found that this can be accomplished by providing a base member which can be readily deformed to conform to the support surface, regardless of its configuration, and by providing a U-shaped first support member which can be releasably and movably secured to the base so that the U-shaped member can rotate about its point of attachment for adjustment and access purposes. It has further been found that a pair of opposed L-shaped second support members can be provided and secured to the projecting legs of the first support member so that adjustment can be achieved in a vertical direction and also again about the point of support so that true three-direction adjustment can be achieved. 
     Accordingly, production of an improved bracket assembly of the character above described becomes the principal object of this invention with other objects thereof becoming more apparent upon a reading of the following brief specification, considered and interpreted in view of the accompanying drawings.

     BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring first to FIG. 1, it will be noted that the improved bracket assembly, generally indicated by the numeral 10, includes a base 11, a first support member 20, and a pair of second support members 30, 30. 
     The base 11 includes a central support portion 12 and depending leg members each of which may be divided into two sections 13 and 14. The outermost leg sections 14, 14 each have through apertures 14a, 14a for mounting purposes, as will be described. 
     As noted above and shown in FIG. 1, the leg members of the base are actually formed into two sections 13 and 14 with a score or bend-line 15 interconnecting them. This enables the outboard end members 14, 14 to be deformed or bent about this line to conform to the surface on which the base is to be mounted. Thus, for example, if the mounting were to be on a flat planar surface, the end members 14, 14 would be bent to the condition shown in broken lines in FIG. 1. On the other hand, if the mounting were to be on an arcuate surface such as, for example, the hump formed by the drive shaft of a vehicle, they would be in the full line position of FIG. 1 so that maximum flexibility and adaptability, as far as the mounting surface, is achieved. 
     The first support member 20 is a U-shaped member having a base 21 and opposed upstanding legs 22, 22. These upstanding legs have at least two through apertures 23a and 23b disposed along the longitudinal axis of the leg to provide for a range of adjustment, as will be described. The base 21 of the first support member 20 may be releasably and adjustably secured to the central support portion 12 of the base 11 by the wing nut 24. This permits disassembly, if desired; but also permits adjustment of the device about the axis of the wing nut or, in other words, in the direction of the arrow 50 (see FIG. 3). 
     This has particular utility, for example, when the device is mounted over the drive shaft hump of an automobile or other vehicle, since the entire assembly can be swung to face either the driver or passenger, as desired. 
     The second support members 30, 30 are L-shaped in configuration with the long legs 31, 31 thereof, each having an elongate slot 31a disposed along the longitudinal axis thereof. This permits attachment to the legs 22, 22 of the first support member W by nut and bolt means 33, 33, and also permits adjustment in the direction of the arrow 60 or vertically or pivotally in the direction of the arrow 40 so that the device may be raised or lowered and also swung at an angle with regard to the horizontal to facilitate reading of the face of radio R. 
     The short legs of each of the second support members 30, 30 designated by the numerals 32, 32, each have a first slot 32a extending along the longitudinal axis of the leg, and a second slot 32b extending at right angles thereto. These are attached to the usual radio engaging bracket of the radio or other appliance. Utilization of the slots 32a and 32b, of course, makes it possible to accommodate varying sizes of radios or other appliances. The radio R and the one form of conventional support bracket have been illustrated in phantom in FIGS. 1 and 4 to show their relationship to the mounting bracket assembly of this invention. 
     Accordingly, it will be seen how the improved mounting bracket assembly, which is the subject of this application, is adaptable to mounting on either planar or arcuate surfaces by virtue of the flexibility and adjustability of the legs 14, 14 of the base 11. 
     In use of the improved mounting bracket assembly, the legs of the base 12 will first be deformed to conform to the support surface, as described above. Following this, the base may be secured to the supporting surface by screws or bolts (not shown). 
     First support member 20 is then attached to base 11 by wing nut 24. In this fashion, member 20 and base 11 may be securely interconnected, but movement of member 20 about a vertical axis in the direction of arrow 50 is possible. 
     Second support members 30, 30 may then be secured to the legs 22, 22 of first support member 11 by nut and bolt assemblies 33, 33. A number of adjustments are possible with this interconnection. 
     First, support members 30, 30 are adjustable about a horizontal axis or in the direction of arrow 40 (see FIG. 2). Second, members 30, 30 are adjustable in a vertical plane in the direction of the arrow 60 (see FIG. 1) by virtue of slots 31a, 31a. Third, a still further range of adjustment in the direction of arrow 60 is made possible by selecting between the apertures 23a, 23b in the legs of the first support member 11. 
     Furthermore, the bracket structure permits adjustment and movement of the assembly and the device carried by the assembly in a plurality of directions while retaining a secure mounting for the appliance. Thus, the adjustment features above described permit movement about a vertical axis in the direction of arrow, about a horizontal axis in the direction of arrow 40, and in a vertical plane in the direction of aarow 60 so that access to radio R is greatly facilitated. 
     While a full and complete description of the invention has been set forth in accordance with the dictates of the Patent Statutes, it should be understood that modifications can be resorted to without department from the spirit hereof or the scope of the appended claims. 
     For example, it will be noted that the invention has been primarily described as being used with a radio R, but it is believed apparent that other appliances or other articles such as radio-telephones, compasses, stereos or depth finders could be mounted thereon.
