Cross-Reference to Related Application
This application is related to copending commonly-assigned U.S. Pat. No. De. 282,465 for a communications Handset.
Background of the Invention
The present invention relates to telephones and, more particularly, to improved means for mounting a mobile telephone in an automobile or the like.
Mobile telephones are becoming increasingly popular, although the basic design of the handset (i.e., the receiver portion) is becoming somewhat standardized (namely, a one piece unit with integral speaker, microphone and controls). The vehicle in which the handset is mounted is not. The purchaser or user of a mobile telephone is likely to find that the portion of his automobile dashboard or console upon which he would like to mount the handset for convenience of use is angled or sloped in a manner that makes use and/or storage of the handset, considering the usual mounting arrangement, awkward or difficult. Thus, a simple handset mounting arrangement is needed which is universally adaptable to the variety of surfaces found in today's automobile so as to facilitate the use and or storage of the handset.
Summary of the Invention
Accordingly, it is the primary object of the present invention to provide a universal mount which permits the mounting of a telephone handset in a plurality of orientations.
It is a further object of the present invention to provide an improved handset mount which is adaptable to a variety of sloping mounting surfaces.
It is yet another object of the present invention to provide a universal handset mounting arrangement which is simple to install and inexpensive to manufacture.
Briefly stated, the above objectives are accomplished in one embodiment of the present invention which provides an arrangement for mounting the handset in five different orientations. A wedge-shaped mounting plate for mounting on a dashboard, console or the like is provided with four counterbores or sockets arranged in a generally square pattern on each of its major surfaces, the sockets of each surface being back-to-back with common axes and interconnecting bolt holes. A handset hanger for receiving the telephone handset has a pair of rearward projecting bosses sized to fit in the sockets of either side of the wedge-shaped mounting plate. Depending on which sockets are selected, the handset hanger will assume one of five different orientations with respect to the mounting plate and the surface upon which the mounting plate is mounted. Means are provided for securing the handset hanger to the mounting plate and the mounting plate to the mounting support surface, such as the dashboard.

Brief Description of the Preferred Embodiment
Referring to the drawings wherein like numerals correspond to like elements throughout, attention is first directed to FIG. 1 wherein in a mobile telephone handset 10 is depicted mounted on an improved universal mount 12. The telephone handset 10 is of the usual cradle type, having a microphone in end 16 which is placed near the users mouth, a speaker at end 18 which is placed against the users ear, a control pad 20 containing touchpads for each of the various numbers and other features built into the telephone and which do not comprise the subject matter of the present invention, and an electrical cord 22 connecting the handset to the transceiver which is usually located in the trunk of the automobile.
Mount 12 is shown to comprise two portions, a wedge-shaped mounting plate 24 and a handset hanger 26. Referring also to FIG. 3, mounting plate 24 is shown to be generally square in plan form with a base 28 and an opposed inclined face 30. Base surface 28 is provided with four cylindrical counterbores or sockets 32 arranged in a square pattern, the axes of the sockets being perpendicular to base surface 28. In a similar manner, face 30 is provided with four counterbores or sockets 34 in back-to-back relationship with sockets 32 and having common axes. Thus, sockets 34 are perpendicular to base surface 28 and angled with respect to face 30. Back-to-back pairs of sockets 32, 34 are connected by holes 36, 38, holes 38 being longer because of the increased thickness at the bottom of the wedge-shaped plate 24.
Referring now to FIGS. 1 and 2, the handset hanger 26 is shown to comprise a generally L-shaped hollow shell 40 defining an interior cavity 42. The base leg of hanger 26 is provided with a hook member 44, which is adapted to engage a mating slot 46 formed within handset 10, and a magnet 48 which cooperates with a metal strip 50 on handset 10 to retain the handset on its hook member 44. Magnet 48 is preferrably of the snap-in type taught in U.S. Pat. Nos. 3,425,729 and 3,451,707, the magnet being necessary because the housing of handset 10 and hanger 26 are preferrably made of a plastic material, Lexan.TM. polycarbonate resin being the preferred choice for hanger 26. Handset 10 and handset 26 are further depicted in copending commonly-assigned U.S. design patent application Ser. No. 06/562,200 filed Dec. 16, 1983.
The back leg of hanger 26 has attached thereto within cavity 42 a pair of spaced apart, rearwardly projecting cylindrical bosses 52 sized to be received within pairs of sockets 34 or 32. The outer dimensions of hanger 26 are such that mounting plate 24 is partially received within cavity 42 when bosses 52 are inserted into their mating sockets. Bosses 52 are each provided with a forward facing counterbore 54 with holes 56 extending through the shell at the base of the counterbores and in general alignment with holes 36. Screws 58 through holes 36, 56 secure the hanger to the mounting plate and the mounting plate to a support surface 60. As depicted in FIG. 1, support surface 60 is substantially vertical, so mounting plate 24 is positioned as shown with inclined face 30 within housing 26 such that bosses 52 engage the sockets on the inclined face. Thus, hanger 26 is mounted generally perpendicular to support surface 60 and handset 10 can hang generally vertically.
Consider now the configuration of FIG. 4 in which hanger 26 is mounted in a downward sloping direction with respect to support surface 60 either because support-surface 60 which represents an automobile dashboard, console or the like, is sloped back or, if surface 60 is vertical, the user prefers his handset to be mounted other than vertical. In FIG. 4, base surface 28 is received within hanger cavity 42 such that bosses 52 engage a pair of sockets 32. As with configuration of FIG. 1, bosses 52 are firmly seated within the sockets to preclude wobble, and the hanger and mounting plate are secured together and to support surface 60 by means of screws 62.
FIGS. 5, 6 and 7 depict alternative configurations in which the mounting plate is rotated 90.degree., 180.degree. and 270.degree., counterwise, respectively, when viewed from the front. This results in upward, left and right facing hangers, respectively, with respect to the support surface. Thus, four possible orientations of the housing with respect to the mounting plate and support surface are possible when the hanger is mounted against base surface 28 (FIGS. 4 through 7). Yet another orientation is possible (FIG. 1) when the hanger is mounted against inclined face 30. Whichever surface (28, 30) is not against hanger 26 abuts mounting surface 60. Accordingly, surfaces sloped in any direction, as well as unsloped surfaces, can be accommodated with this universal mounting arrangement.
In yet another embodiment of FIG. 8 a magnet 64 is secured to the base surface 28 of mounting plate 24 by means of a screw 66 threaded into hole 68 in the mounting plate. This would be accomplished after mounting plate 24 and hanger 26 had been secured together as through the use of bolts through cooperating holes 36, 56 (FIG. 1). Such a magnet provides a convenient means for removably attaching mounting plate 24 to a metallic surface.
The best mode for carrying out this invention has been set forth in the description above. In particular, this has been accomplished by setting forth preferred structral arrangements incident to successful practicing of the invention in the best way contemplated at the time of executing this patent application.
It should be obvious to one skilled in the art that certain changes can be made to the above-described invention without departing from the inventive concepts thereof. For example, instead of providing the mounting plate with four holes (36, 38) therethrough, arranged in a square, other patterns of spaced holes (greater than four) could be utilized as long as the hole pairs mated with the pair of bosses 52 at different orientations of the support plate. In addition, the hanger need not be hollow, and the bosses could assume any (equal) lengths depending upon how much, if any, of the mounting plate was desired to be covered by the hanger. Further, it is apparent that the mounting plate of FIG. 1 could be rotated 180.degree. such that holes 38 align with boss holes 56 to provide a greater stand-off distance for the hanger from support surface 60 which may be useful in allowing the handset 10 to clear a nearby obstacle. Furthermore, it is anticipated that the handset holder may be mounted together with the mounting plate using screws and nuts, then mounted to the dash board, etc. with double sided tape or other non-hardware methods to achieve the desired angle. And, the counterbores or sockets in the mounting plate can conveniently accommodate blind nut arrangements. It is intended that the appended claims cover these and all other variations in the present invention's broader inventive concepts.
