MOUNT BAR FOR VIDEO RECORDING AND DISPLAY DEVICES TECHNICAL FIELD
- BACKGROUND OF THE INVENTION
The present invention relates to mount bars for video recording and display devices. More particularly, the present invention relates to a mount bar that attaches to seats in motor vehicles for supporting video recording and display devices for use therein.
Movie cameras, and most recently, video tape cameras and recorders, have facilitated the recording and display of action through movies and television. In order to record action scenes, cameras have been mounted on a variety of devices. These devices include stationery mounts for recording movement of objects passing before the camera, as well as mounts which are positioned in moving objects. The ability to position a camera in a variety of locations permits a film director to record a number of different view points from which to observe the action. My United States Patent No. 5,833,101 discloses a mount bar for supporting a video camera from a motor vehicle for recording images from the motor vehicle. However, storage and handling of the disclosed mount bar may be impractical for some motor vehicles, and may be bulky to carry.
For recording images received by the video camera, a video tape recorder is held in the motor vehicle. Video tape recorders typically mount in the trunks of motor vehicles. Trunk mounting may be satisfactory in some instances, but generally this is impractical. The recording device requires remote control devices for operation of the recorder. Tapes can not be readily checked or replaced. The recorder occupies space that may be required for other goods. However, merely placing the recorder on the floorboard of the motor vehicle is not practical either. The recorder blocks the floor space for the comfortably positioning of feet, and can readily slide around. This may damage tapes being used in the recorder or cause other problems for persons in the motor vehicle.
Also, the use of motor vehicles, particularly automobiles, is a common way for families to make long distance travel trips. Entertaining children, and even adults, during such trips often requires special efforts. Often the travelers read, listen to music or the radio, talk, sightsee, in order to pass the time. Watching video recordings during trips however is becoming more prevalent, particularly with the development of small televisions with video recording players that are operable on 12 volt supply provided by the automobile. Devices have been lacking for adequately securing these televisions for safe travel. Custom vans for instance provide special housings that attach to the floor of the van. Others mount video screens in the backs of seats. For conventional automobiles, these are not entirely satisfactory. Permanent special housings are not practical and further do not permit selective installation for long trips and removal for in-town travels.
- SUMMARY OF THE INVENTION
Accordingly, there is a need in the art for an improved mount bar which rigidly secures to seats of motor vehicles for use in supporting video equipment for receiving, displaying, and recording images of objects from the motor vehicle. It is to such that the present invention is directed.
The present invention meets the needs in the art by providing improved mount bars which rigidly secure to seats of motor vehicles for use in supporting video equipment for receiving, displaying, and recording images of objects from the motor vehicle. The mount bar comprises an elongate member for being attached to a seatback of a motor vehicle. The mount bar defines a support surface to which an image receiving device is pivotally mounted, whereby the image receiving device can be selectively tilted for adjusting the angle of the view for receiving images. The opposing end portions of the elongate member are adapted for connecting to respective seatbacks of the motor vehicle in which the mount bar is installed. A frame for supporting an image display device is detachably connected to the elongate member. The frame comprises a pair of side supports adapted for attaching at respective first ends to the elongate member. A shelf attaches to respective second ends of the side supports for receiving the image display device that is secured to the shelf. A pair of opposing arms extend laterally from the pair of side supports for bearing against a back surface of a respective seat in a motor vehicle, for preventing sway of the frame during operation of the motor vehicle. Means are provided for securing a distal end of the frame to the seat of the motor vehicle.
Alternate embodiments of the mount bar are disclosed, including a mount bar for supporting a video camera laterally of a headrest, a mount bar that comprises a pair of elongate members rigidly connected together, a mount bar with telescopically received members, and a mount bar with members that pivot from first positions for storage and handling to second positions for use in supporting video equipment in motor vehicles.

Referring now in more detail to the drawings in which like parts have like identifiers, FIG. 1 illustrates in perspective view a mount bar 10 attached to a seat 12 in an motor vehicle for supporting video recording and display devices according to the present invention. The seat 12 can be bench-style or spilt bucket-style as illustrated. In the illustrated embodiment, the mount bar 10 comprises an elongate tube 14 having a rectangular cross-section. The tube 14 has opposing sides 16, 18 and opposing upper and lower sides 20, 22. The side 16 bears against legs 24 for a headrest 26 that extend from a seatback 28 in a motor vehicle. In an alternate embodiment, the mount bar 10 is a rigid angle member that defines an L-shape in crosssectional view. The angle member has substantially perpendicular surfaces that correspond to the side 16 and the upper side 20 for connecting this embodiment to the legs 24 of the headrest 26 and to video recording and display devices, as discussed below.
The mount bar 10 supports a video display frame, generally 30. The frame 30 includes a pair of opposing side members 32 and opposing top and bottom members 34, 35. The top member 34 defines a plurality of openings 36. Fasteners 38 extend through openings 40 in the mount bar 10, and engage connectors 42 for attaching the support 30 to the mount bar 10. A shelf 44 attaches at distal ends of the side members 32 and to the bottom member 35 that provides support for the shelf 44. A video display device 46 mounts to the shelf 44. The video display device 46 can be a video monitor, conventional television, an LCD display screen, or other such image display device. In the illustrated embodiment, the device 46 includes threaded bores 48 in a lower surface which receive fasteners 50 through aligned openings 52 in the shelf 44. In an alternate embodiment, straps (not illustrated) secure the device 46 to the shelf 44 and the support 30.
In the illustrated embodiment, a video recorder 52 is suspended from a lower surface of the shelf 44. In a first embodiment, the casing or housing for the video recorder 52 includes laterally extending flanges 53 with openings 51 for receiving threaded fasteners that connect the casing to the shelf, as best illustrated in the enlarged partial detailed view. FIG. 1 also illustrates a second embodiment for suspending the video recorder. This embodiment has a brace 54 with a cross-section that conforms to the shape of the casing. Lateral distal ends 55 of the brace 54 define openings for receiving the fasteners to secure the video recorder 52 to the shelf 44. A pair of the braces may be required to support the recorder 52. A pair of opposing arms 60 extend latterly from the side members 32. Each arm 60 includes a plate 62 which bears against the seat back 28 in the illustrated embodiment, a pair of straps 64, 66 attach to the arms 62. The straps 64, 66 are preferably a strong woven fabric, such as a seat belt material. The straps 64, 66 terminate in mating the buckles 68, 70. A portion 72 of the strap 66 extends from the buckle 70 for tightening the strap when the buckle 68, 70 is connected. Preferably, the straps 64, 66 extend around a seat post that anchors the seat 28 to the floor of the motor vehicle.
The upper side 20 of the tube 14 supports a video recording device such as a video camera 70. The sides 20, 22 each define opposing elongated slots 72 which are aligned to each other and parallel to a longitudinal axis of the tube 14. The slots 72 are preferably positioned central between the distal ends 74, 76 of the tube 14. The sides 20, 22 further define the opposing aligned openings 40 which are spaced apart from the distal ends of the slots 30. The openings 40 receive the threaded fasteners 38 that engage the connectors 42, for attaching the frame 30 to the tube 14, as discussed below.
The tube 14 receives a camera mount, generally designated 80. The camera mount 80 comprises a support block 82 having at least one tapped bore 84 which receives a bolt 86 extending through the slots 72 of the tube 14 to secure the support block to the tube. A pair of flanges 88, 90 extend upwardly at a side portion of the support block 82. The flanges 88, 90 have a trapezoid shape in end view, with the wider base of the trapezoid integral with the support block 82. The flanges 88, 90 define coaxially aligned bores 92, 94 with the bore 92 being threaded for receiving a threaded fastener 96. A pivot plate 98 includes a depending trapezoid-shaped flange 100 that defines a bore 102. The flange 100 is disposed laterally inward of an edge of the pivot plate 98, whereby the flange can be disposed between the pair of flanges 88, 90. The pivot plate 98 defines a hole 104 for receiving a threaded fastener 106 for engaging the camera 70 to the pivot plate with a bolt. The supporting block 82 and the pivot plate 98 are readily manufactured, such as by extrusion or molding with minimal machining required.
The sides 16, 18 define at least one pair of elongated slots 106. In the illustrated embodiment, the sides 16, 18 define two pairs of slots 106, 108 which are spaced apart and coaxially aligned and substantially parallel to the longitudinal axis of the tube 14. Brackets 110 secure the tube 14 to the legs or supports 24 of the headrest 26. The bracket 110 comprises a block having a first face 112 and a second face 114 which is recessed relative to the first face. A land 116 projects from the face and is sized to extend through the slots 106, 108 in the tube 14. The bracket 110 also defines a bore 116 for receiving and securing a threaded fastener 118 which extends through the respective slots 106, 108. The first face 112 accordingly provides a planer surface for abutting against the face 16 of the tube 14. The second face 114 abuts against a face of the headrest support 24.
FIG. 2 is a perspective view of a camera mount bar 130 for attaching to the legs 24 of the headrest 26 extending from the seat back 28 of a seat in a motor vehicle. The camera mount 130 is preferably a tube having opposing sides 132, 134 and opposing top and bottom sides 136, 138. The sides 132, 134 define elongated slots 142, 144 which are coaxially aligned and substantially parallel to the longitudinal axis of the tube. Two opposing slots 146 are defined in upper and lower sides 136, 138 of the tube 130. Fasteners 96 extend through the slots 146 to rigidly connect the camera mount 80, discussed above, to the tube 140, for pivotally supporting a camera on the mount bar 130. The brackets 110 cooperate with the fasteners 118 to connect the tube 130 to the legs 24 of the headrest 26.

FIG. 4 is a perspective view of an alternate embodiment 170 of a mount bar of the present invention for attaching to the headrest supports 24 extending from a seat 28 in a motor vehicle. The mount bar 170 is an elongated member formed from a pair of side members 177 and a central member 174. In the illustrated embodiment, the side members 172 and the central member 174 are elongated openended tubes. However, the present invention is readily embodied in L-shaped angle members. The central member 174 has opposing distal ends which telescopically receive one of the pair of members 172. The central member 174 has an equipment support or mounting surface 176 that defines an elongated slot extending parallel to a longitudinal axis. The opposing surface in the tube also defines an opposing slot. A mounting surface 180 transverse to the support surface 176 defines a pair of longitudinal second slots 182, 184. The second slots 182, 184 are spaced apart and defined at respective distal ends of the central member 176. The opposing surface of the tube defines an opposing slot.
The camera mount 80 discussed above connects with fasteners 96 that extend through the opposing slot 178 for selectively positioning the camera mount on the mount bar 170. As discussed above, the camera mount 80 pivotally connects the video camera 70 at a selected angle relative to the support surface, whereby the video apparatus can be selectively tilted for adjusting the angle of the view.
The pair of side members 172 each define an elongated slot 186 in a side face 188. In the illustrated embodiment, the tubular side members define slots in the opposing face. The slot 186 aligns with a respective slot 182, 184 in the mounting surface 176 of the central member 174 upon telescopically sliding the side members 172 with the central member. The slots 186 receive the brackets 110 and fasteners 118 for securing the elongate member 170 to the legs 24 of the headrest 26 of a seatback 28. The 118 fasteners extend through the aligned slots 186, 182 and 186, 184, so that the side members 172 are also secured to the central member 174.
FIG. 5 is a perspective view of an alternate embodiment 190 of a mount bar of the present invention for attaching to the headrest support 24 of a seat 28 in a motor vehicle. The mount 190 has a pair of members 192 that are hingedly connected together by a connector 194. The connector 194 is generally U-shaped in cross-sectional view with an open side 196 for pivotal movement of the members 192. Each member 192 defines at least one elongated slot 198 in a side face for bearing against the headrest support 24 extending from the seat in a motor vehicle. The distal end of each member 192 also defines an opening 200 which receives a pivot pin 202. One of the members further has an equipment support or mounting surface 204 that defines an elongated slot 206 extending along a longitudinal axis.
The connector 194 receives the pair of spaced-apart pins 202. These extend through the respective openings in the end portions of the members 192. The members 192 pivot on the pins 202 from a first position with the members closely together and a second position with the members substantially coaxially aligned.
The slots 198 in the opposing sides of the members 192 receive the brackets 110 and the fasteners 118 for securing the elongate member 190 to the legs 24 of the headrest 26 of a seatback 28 (not illustrated). The camera mount 80 connects with fasteners 96 that extend through the slot 206 for selectively positioning the camera mount on the mount bar 190. The mount 80 pivotally connects the video camera 70 at a selected angle relative to the support surface 204, whereby the video apparatus can be selectively tilted for adjusting the angle of the view.
With reference to FIG. 1, the mount bar 10 and the video display frame 30 are used to support the video display device 46 in a motor vehicle. The connectors 110 and the fasteners 118 connect the mount bar 10 to the headrest supports 24. The video display device 46 connects with cabling (not illustrated) to a tape recorder. In the illustrated embodiment, the tape recorder 52 is suspended from the shelf 44 of the frame. The video camera mounts with the pivotable support 80 and fasteners 96 to the mount bar 10. The video camera 70 receives images which can be recorded on the recorder 52 and/or displayed on the video display device 46. It is to be appreciated that the frame 30 is likewise useful for supporting a video game apparatus as a substitute for the video recorder device, for playing electronic games during long trips.
The straps 64, 66 extend around a seat post to restrain the frame 30 from swaying during operation of the motor vehicle. The plates 62 likewise bear against the back of the seat 28, to restrain sway.
With reference to FIG. 2, the camera mount bar 130 provides a shorter length apparatus for supporting the video camera 70 laterally of the headrest 26. The bar 130 mounts to the supports 24 with the connectors 110 and fasteners 118. The video camera is selectively positioned along the slot 146, and connected with cables to a video display or recorder, for receiving, recording, and displaying images from the motor vehicle.
With reference to FIG. 3, the mount bar 150 is likewise readily stored and easily assembled for installation to the seats of a motor vehicle, as discussed above. The fasteners 164 secure the members 152, 154 rigidly together. Although not illustrated, the bar 150 readily receives the frame 30 discussed above, with the addition of openings 40 for the fasteners 38, 42.
With reference to FIG. 4, the mount bar 170 selectively attaches to the supports 24 by sliding the members 172 longitudinally in the connector member 174. The connectors 110 and fasteners 118 secure the members 172, 174 together and to the supports 24. The video camera 70 then connects with the mount 80 for selective angle of receiving images from the motor vehicle. Although not illustrated, the bar 150 readily receives the frame 30 discussed above, with the addition of openings 40 for the fasteners 38, 42.
With reference to FIG. 5, the mount bar 190 operates by pivoting the members 192 from the first position to the second position. The first position facilitates storage and handling of the elongate member. The members 192, being pivoted to the second position, define the elongated member 190 for connecting at opposing distal ends to the headrest supports 24 extending from the back of the seat in the motor vehicle. With the member 192 coaxially aligned, the mount 190 is connected with the brackets 110 and fasteners 118 to the headrest supports 24. The camera mount 80 is attached with the fasteners 96 and the video camera 70 is attached, for receiving images at a selected angle of view. The brackets 110 and the fasteners extend through the slots 198, for connecting to respective headrest columns 24 extending from the seatback of the motor vehicle in which the mount is installed. Although not illustrated, the bar 150 readily receives the frame 30 discussed above, with the addition of openings 40 for the fasteners 38, 42.
The principles, preferred embodiments, and modes of operation of the present invention have been described in the foregoing specification. The invention is not to be construed as limited to the particular forms disclosed because these are regarded as illustrative rather than restrictive. Moreover, variations and changes may be made by those skilled in the art without departure from the spirit of the invention as described by the claims.
