Description:
FIELD OF INVENTION  
         [0001]    The present invention relates generally to portable video camera filming directional control equipment, and more particularly to battery powered wirelessly remote control weather resistance personal hand-held video camera accessory. This invention requires the user&#39;s interaction to determine the correctives of the direction via a generic video camera during the filming process. This present invention is rain resistance and suitable for outdoor application.  
         BACKGROUND OF THE INVENTION  
         [0002]    Personal handheld video camera has been very popular for many years. People use them in filming of indoor and outdoor event everyday. However, the camera operators are usually not in the film themselves. Sometimes tripods are used but still require someone to keep moving the filming direction in order to capture the whole occasions momentarily. It is a shame when reviewing the memory of the filmed video and the head of household is always not in the film.  
           [0003]    It is always a possibility for the video camera to get wet when it is mounted on a tripod when filming home events in a cloudy day where rain is unpredictable especially in tropical climate. Sometimes video camera can be damaged by rain.  
           [0004]    Thus there is a need for a video camera stand to provide the operator to control the filming direction from a remote distance. This camera stand should simulate a person&#39;s hand such that it can rotate back and forth horizontally and tilt up and down vertically. This will allow the operator to capture his/her own image in the video record.  
           [0005]    Further, there is also a need for a video camera rain protector such that light rain or sudden rain will not damage the video camera. In addition, this device has to be low cost, portable, easy to operate, light weight, battery powered and rugged.  
           [0006]    The present invention provides such a video camera mounting system.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0030]    [0030]FIG. 1 is the front view of the overall system of the remote-control self-video capturing weather resistance portable video camera mounting system, which includes a handheld device controller  3 , a main system  2 , a rain jacket  4  covering the main system  2  and a camera rain shield subassembly  5 , according to the present invention. As seen in the figure, a generic handheld video camera  6  with the LCD screen  7  is facing the front direction is mounted onto the main system  2  inside the camera rain shield  5 .  
         [0031]    The stator base  8  is the stationary reference of the main system  2 . The rotor subassembly  9  rotates relatively to stator base  8  through the rotational axis. The horizontal rotational motion is driven by the horizontal motion motor-driver-subassembly  31  and has the capability to rotate in either clockwise or counterclockwise direction infinitely which is defined as without any angular limitation.  
         [0032]    The vertical rotational tilt motion is driven by the vertical motion motor-driver-subassembly  26 . The video camera is mounted to the video camera mounting subassembly  14  by the thumbscrew  16 . The video camera mounting subassembly is mounted to the vertical motion worm gear  12  by the thumbscrew  18 . The vertical motion worm gear  12  is assembled to the rotor subassembly by the pivot shaft  11 . The vertical motion worm gear  12  is precisely mated to the vertical motion motor-driver subassembly  26 . As a result the video camera mounting subassembly  14  rotates relatively to the rotor subassembly  9  by pivoting through the centerline axis of the pivot shaft  11 .  
         [0033]    Both the vertical motion motor-driver-subassembly  26  and the horizontal motion motor-driver-subassembly  31  are connected electrically to the main PCBA  30  and are all mounted to the rotor subassembly  9 . Power switch  101  controls the power supply to the PCBA  30  and is also mounted to the rotor subassembly  9 .  
         [0034]    In practice, the operator  118  turns on the power of the video camera  6  and rotates the LCD screen  7  of the video camera towards the video camera focusing direction as in the FIG. 1. Then the operator  118  will switch the video camera  6  to camera mode, which allows the view to be shown on the LCD screen  7 . The operator then turns on the power switch of the handheld controller device  3  and the power switch  101  of the main system  2 . The operator  118  uses the handheld controller  3  to control the main system  2  to rotate and tilt the video camera  6 . Switch  89  and switch  95  are spring return 3 position switches with normally set at center neutral position. When the switch  95  is activated to either left or right direction, the PCBA  97 , which consists of electronic components and programmable components, of the device controller  3  will detect the input and generate a signal  98 . This signal  98  can be a radio frequency signal or an infrared (IR) signal and is then emitted out wirelessly. The main PCBA  30  is equipped with signal receiver for either radio frequency signal or infrared (IR) signal matching with PCBA  97 . This main PCBA  30  which consists of electronic components and programmable components, will detect the signal  98  and then generate the electronic driving functions to drive the horizontal motion motor-driver-subassembly  31 . In results the rotor subassembly will rotate in either clockwise or counterclockwise direction accordingly.  
         [0035]    When the switch  89  is activated to either up or down direction, the PCBA  97  of the device controller  3  will detect the input and generate a signal  98 . This main PCBA  30  will detect the signal  98  and then generate the electronic driving functions to drive the vertical motion motor-driver-subassembly  26 . In results the video camera mount subassembly will tilt up or down accordingly.  
         [0036]    As the video camera moves to the preferred direction, the operator  118  can see himself/herself on the LCD screen and use the video camera remote controller  119  to zoom and record his/her own image.  
         [0037]    The rain jacket  4  covers and seals off rain from the top and the upper portion of the side of the rotor subassembly  9 . This rain jacket  4  is made of soft and elastic material such as polyester, nylon, rubber, and silicon rubber and may be transparent. This soft and elastic material permits the rain jacket  4  will stretch and fold as the vertical worm gear  12  tilts up and down. It also protects the power switch  101  from rain but permit the operator to turn the power switch  101  on or off from outside of the rain jacket  4 .  
         [0038]    The video camera rain shield subassembly  5  is mounted to the worm gear  12  by thumbscrew  110 . The shield  107  is made of transparent material such as polycarbonate, acrylic or glass. It covers the top and all sides of the video camera  6  and the LCD screen  7 . It protects the video camera  6  from rain by let the LCD screen to be viewed from outside. The video camera rain shield subassembly  5  should be large enough to facilitate a generic handheld video camera with the LCD screen flipped out to the side.  
         [0039]    [0039]FIG. 2 is the front view of the main system  2 , according to present invention. The stator base  8  is the base support of the complete system. As also seen in FIG. 2-FIG. 13, the rotor cover  117  protects the inside components from rain. The pivot shaft  11  passes through the pivot support arm  10 , then the worm gear  12  and another pivot support arm  10 . Then it is locked in place by the washer  19  and the OD retainer  20 . As shown at least one pivot support arm  10  is used to facilitate the supporting structure. This allows the worm gear  12  to be able to pivot through the axis of the pivot shaft  11  relatively to the pivot support arm  10 . The rain jacket  4  with an opening smaller than the neck  13  of the worm gear  12  slips over the neck  13  of the worm gear  12 . The elastic property of the materal used of this rain jacket  4  provides a tight wrap around the neck  13  and forms a rain seal around the neck  13 . The rest of the rain jacket  4  flare out and cover over the top and the upper portion of the vertical wall of the rotor cover  117 . It results that all components covered by the rain jacket in the outside chamber  40  will be protected from rain.  
         [0040]    The camera mount  14  is assembled to the worm gear by the thumbscrew  18  mounting at the threaded hole  28  of FIG. 3. As shown a least one thumbscrew will facilitate the assembly. The pad  15  provide a soft mounting surface for the video camera  6  which is assembled to the camera mount  14  by the thumb screw  16 . The knurl head  17  of the screw  16  provides easy assembly processes for mounting and dismounting the video camera.  
         [0041]    This present invention is a portable system. The traction foot  21  is made of rubber or silicon rubber type material and designed to have high coefficient of friction on the bottom surface. It is adhered to the bottom flare  120  of the stator base  8  by means of pressfitting, double sided adhesive tape or adhesive alike. At least 3 traction feet are used to facilitate the support of the main system. As shown, 6 feet are used for better balance. The traction feet provide friction against sliding along the surface where the main system  2  is resting on. This allows the system to function and be save to operate on some slightly unleveled surfaces such as shelves, tables, car roofs and hoods etc.  
         [0042]    The bottom flare  120  extends out from the edge of the stator base  8 . It provides better roll and tilt ratio that the center of gravity of the complete system with video camera  6  mounted will not be easily knock down accidentally.  
         [0043]    [0043]FIG. 3 is the cross section view of FIG. 2 along  2 - 2 . It shows the relationship between the rotor subassembly  9 , rotor  22  and the stator base  8 . The worm gear  36  is mounted onto the stator base  8  by the screw  32 . As shown, at least one screw  32  is used to facilitate the assembly. The rotor  22  is mounted to the worm gear  36  by means of the pivot shaft  34  which is locked in place by the washer  33  and the OD retainer  35 . The pivot shaft  34  is part of the rotor  22  by assembly, casting, molding or welding. The material choice for the rotor  22  and the pivot shaft  34  can be hard plastic, graphite or metal. Phosphorus bronze and stainless steel are the best material choice for the pivot shaft  34 . The rotor  22  rotates through the center axis of the pivot shaft  34 . The ID of the center hole of the worm gear  36  is slightly larger than the OD of the pivot shaft  34  and serves as the bearing surface  24  mating to the OD of the pivot shaft  34 . The worm gear can be made of hard plastic, graphite or metal. Phosphorus bronze and stainless steel are the best material choice for this worm gear  36 . Gear lubricant, grease or Teflon coating is applied to the bearing surface  24  and the OD of the pivot shaft to minimize friction.  
         [0044]    The horizontal motion motor-driver subassembly  31  is mounted to the rotor  8  and provides the rotational direction to the rotor  8 . As a result the rotor  8  rotates relatively to the stator base  8 .  
         [0045]    The weather seal  23  is assembled onto the wall  37  of the stator base  8 . The weather seal is made of elastic material such as rubber and silicon rubber. The top surface of the seal  23  exerts a light pressure against the bottom surface of the rotor  22  and provides a seal against rain from entering into the inside chamber  39 . The rotor cover lip  121  of the rotor cover  117  covers edge of the top surface of the rotor  22  and prevents rain from entering into the upper chamber  41 .  
         [0046]    The main PCBA  30  is mounted onto the rotor by screw  42  in the upper chamber  41 . It is consisted of electronic components and firmware which will receive wireless signals  98  from the handheld device controller  3  and transfers them into electronic signal to drive the horizontal motion motor-driver subassembly  31  and the vertical motion motor-driver subassembly  26  respectively. The vertical motion motor-driver assembly  26  is mounted onto the rotor  22  inside the upper chamber  41 .  
         [0047]    The worm gear  12  rotates against the center axis of the pivot shaft  11 . The ID of the center hole of the worm gear  12  is slightly larger than the OD of the pivot shaft  11  and serves as the bearing surface  29  mating to the OD of the pivot shaft  11 . This pivot shaft  11  is made of metal and stainless steel is the best choice. The worm gear can be made of hard plastic like ABS or metal. Phosphorus bronze and stainless steel are the best material choice for this worm gear  12 . Gear lubricant, grease or Teflon coating is applied to the bearing surface  29  and the OD of the pivot shaft to minimize friction.  
         [0048]    The shoulder  38  of the worm gear  12  is the physical stop for the rain jacket  4  to slip any further downward. The center opening of the rain jacket  4  slips over the neck  13  of the worm gear  12 . The inside perimeter of this opening is shorter than the outside perimeter of the neck  13  section of the worm gear  12 . The elastic material property of the rain jacket  4  will exert a pressure along the contact area between the center opening of the rain jacket  4  and the surface of the neck  13  of the worm gear  12 . This forms a seal against rain from entering into the outside chamber  40  area.

The worm gear  36  is mounted to the stator base  8  at the mounting holes  77  by at least one fastener, which can be screw, rivet or other mounting mechanisms to facilitate the assembly. As the result, the worm gear  36  is the fixed or stationary base of the horizontal rotational movement.  
         [0070]    The worm  52  rotates at the same rate as the motor  78  and the worm gear  36  will pivot to the next tooth for every rotation of the worm  52 . In the assembly the worm  52  and the worm gear  36  with the same pitch value are precisely mated to each other. The rotor  22  and all the components assembled to the rotor  22  rotate around the worm gear referencing to the center axis of the pivot shaft  34  whenever the motor  78  rotates. In practice worm gear system provides two advantages to the invention. Firstly, it prevents gear slippage and in turn the electronic system does not have to provide motor holding current to keep the main system  2  to lock in position. This is a unique power saving feature of this invention. Secondly, it provides a very high gear ratio such that a very low output torque motor  78  will be able to rotate the main system  2 .  
         [0071]    As shown in FIG. 10, this system of rotor  22  with all the components assembled to it can rotate relatively to the stator base in either clockwise or counterclockwise direction without angular limitation.
