BACKGROUND OF THE INVENTION
The present invention relates to devices for supporting a camera such as a video camera or a CCD (charge coupled device) camera and, more particularly, to a kinematically reconfigurable camera supporting device which mounts or rests on different objects of various shapes under gravity without clamping to the object.
Video cameras for computers have become increasingly common. For a CRT monitor having a sufficiently wide, generally planar surface on the top, a camera may be placed on the top surface using a flat support, a tripod structure, or the like. For a laptop computer, the display screen is relatively thin so that conventional structures typically do not provide stable support of the camera on the laptop screen or a flat panel screen and do not allow adequate adjustments to be made to position the camera easily and quickly. Some mounting devices are designed to support the camera on a CRT monitor and a flat panel LCD screen in different modes of operation. There remains a need for a camera mount that is easy to use and sufficiently versatile to stably support a camera on various surfaces including a flat surface and edge surfaces of flat screens or the like having a range of different thicknesses.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 and 2, a camera supporting device 10 includes a front support member 12, a right flexible leg 14, a left flexible leg 16, and a tail end 18. The right flexible leg 14 is coupled between the right end of the front support member 12 and the tail end 18. The left flexible leg 16 is coupled between the left end of the front support member 12 and the tail end 18. The front support member 12 includes an upper surface having a camera support location 20 between the left end and the right end on which to support a camera 22. For instance, a ball-in-socket connection can be made between a ball provided at the bottom of the camera 22 and a socket provided at the camera support location 20. Such a connection will allow the camera 22 to rotate in various directions (tilting, panning, etc.) with respect to the camera supporting device 10 to point the camera 22 in a desirable direction. The camera support location 20 is typically disposed in the middle between the right end and the left end of the front support member 12. The camera supporting device 10 may be symmetrical with respect to a mid-plane MP, which intersects the camera support location 20 and tail end 18.
The front support member 12 is typically a longitudinal support member. As best seen in FIG. 2, the front support member 12 includes a lower inwardly arched or cornered surface 30, and a bottom support surface 32 disposed below the lower inwardly arched surface 30. The inwardly arched surface 30 may include an L-shaped arch or corner as shown or a more curved arch. In the specific embodiment shown, the lower inwardly arched surface 30 includes a horizontal support surface 34 facing downward and a vertical support surface 36 facing rearward.
The right flexible leg 14 and the left flexible leg 16 are deformable to adjust the position of the tail end 18 with respect to the front support member 12. The flexible legs 14, 16 may be made of flexible coils which are overmolded to provide a smooth exterior surface. An elastic overmold enhances product stiffness and stability. To form the overmold, the flexible coils are desirably pre-lined with a thin MYLAR, PVC, or the like to prevent the mold material from entering the grooves of the flexible coils and degrading the flexibility of the legs 14, 16. Injection molding may then be used to form the elastic overmold. The flexible legs 14, 16 preferably have shape memory under deformation, so that they retain their shapes until the user adjusts the deformation to different shapes. Such flexible coils are available, for instance, from Uniprise International Inc. of Terryville, Conn.
The tail end 18 desirably includes a tail weight which provides a more stable mounting of the camera supporting device to an object by gravity. The tail weight may be about 30-60 grams. The density of the tail weight is desirably higher than the density of the flexible legs 14, 16, and may be the same or higher than the density of the front support member 12.
FIG. 2 shows the camera supporting device 10 disposed on an object having a generally horizontal surface 40 such as a CRT monitor. The bottom support surface 32 of the front support member 12 and the tail end 18 make contact with the generally horizontal surface 40. The bottom support surface 32 may contact the generally horizontal surface 40 across the length of the front support member 12 between the left end or the right end. Alternatively, the bottom support surface 32 may contact the generally horizontal surface 40 at a surface portion near the left end and another surface portion near the right end if the middle portion of the bottom support surface 32 curves upward. The camera supporting device 10 rests on the generally horizontal surface 40 under gravity without clamping to the object. The tail end 18 is disposed at or below the front support member 12 in elevation, or at or below the rest of the camera supporting device 10 in elevation. The cable 44 of the camera 22 maybe inserted through a space near the tail end 18 between the right flexible leg 14 and the left flexible leg 16. A groove 46 may be provided at the tail end 18 to receive the cable. The intersection of the flexible legs 14, 16 at the tail end 18 allows incorporation of this integrated cable management feature.
In FIGS. 3-5, the camera supporting device 10 is disposed on a top edge of an object 50 such as a flat panel screen. The lower inwardly arched surface 30 engages a vertical front surface 52 and a horizontal top surface 54 forming an edge of the object 50. More specifically, the horizontal support surface 34 of the front support member 12 engages the horizontal top surface 54 and the vertical support surface 36 of the front support member 12 engages the vertical front surface 52. The flexible legs 14, 16 are deformable to adjust the position of the tail end 18 to contact a rear surface 56 of the object 50 to mount the camera support device 10 on the object 50 by gravity without clamping to the object. The tail end 18 is disposed below the front support member 12 in elevation, or at or below the rest of the camera supporting device 10 in elevation. As seen in FIG. 3, the front support member 12 may have a length larger than a maximum horizontal dimension of the camera 22 to provide a more stable support for the camera 22. FIG. 4 shows the integrated cable management feature for the cable 44 of the camera 22 as described above.
The flexible legs 14, 16 of the camera supporting device 10 is user hand-configurable, and have shape memory to hold their positions upon release. The camera supporting device 10 is self-stabilizing under gravity, and provides independent adjustment in six degrees of freedom (three translation and three rotational) to place the camera on flat or uneven surfaces. The kinematically reconfigurable device 10 is easy to use and adjust with no clamping.
The above-described arrangements of apparatus and methods are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims. For example, the shapes and sizes of the components that form the camera supporting device may be changed. The scope of the invention should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the appended claims along with their full scope of equivalents.
