BACKGROUND OF THE INVENTION

This invention relates to a stabilizing platform support for a camcorder which rests on the shoulder of a camera operator to video subjects thereby eliminating up and down motion normally incurred while filming. The platform has a handle which includes a locking pin for locking the handle into position on the platform.

It is common knowledge that camcorders on the market today due to their small size have an inherent problem of producing a poor quality picture due to hand movement of the user which is not stable thus producing a shaky, unsteady and jittery picture. Even with the stabilizing chip that is present in the camcorder body today does not remedy the jittery movements since a user will video for long periods of time and tire while doing so or walk or run while videoing thus magnifying the problem. Another problem with video camcorders is that the remote control that is typically provided with the purchase of a camcorder, for use with the camera, only operates while the user is directly in front of the camcorder. Operating the camcorder from in front with the remote control is not always practical as the user may be to the side of the camcorder or behind the camera videoing an event without wanting to interject his own presence into the subject. Secondly, if you wish to use a tripod, again, you must be in front of the camcorder to send remote infrared control signals.

Prior attempts have been made to eliminate the unwanted up and down motions typical in amateur videoing or photography through a stabilization mechanism which is either supported by the user's shoulder or by a body harness. None of the prior stabilization mechanisms has a provision for instant, infrared signal control for smooth transition of on and off, power and other functions through a handle that holds the infrared remote control unit. The current camcorder controls require manual manipulation to operate which will create a jittery motion to the image that is being videotaped. The current infrared remote control units that are provided as an accessory to the camcorders on the market today operate only when in front of the camcorder.

U.S. Pat. No. 2,370,611 to Du Mais is a bulky and complicated apparatus with interlocking members which hold a still camera and requires a strap around the arm. This is not practical or helpful for use with the camcorders of today.

U.S. Pat. No. 4,542,966 to Knaudt is a shoulder and hand support for photographic equipment which is supported by an arm connection for rapid picture sequence for a still camera. This support uncomfortably hangs over the shoulder like an arch and comes down to the rib cage and includes many locking mechanisms.

U.S. Pat. No. 4,984,090 to Sasaki et al is a grip that can be mounted underneath a camera. Once mounted and electronically connected there is a power switch of a trigger type that will video only when the trigger is depressed. This is not suitable for long-term video taping. The user must hold this camera with one or both hands and there is no stabilizing attachment reaching to the shoulder which can provide stabilization and comfort and ease in the use of the camera especially for long-term video taping.

U.S. Pat. No. 5,038,160 to Schumacher et al is a camera support apparatus which slides into a compact position. The bar is wider at the front and narrows at the back where it rests on the shoulder. This presents a heavier load in the front causing imbalance and discomfort and is not practical in use. The use of slider plates introduces a potential for pinching or injury to the user.

U.S. Pat. No. 5,073,788 to Lingwall is a cumbersome camera apparatus which requires the use of hinges, straps, fasteners and a body harness to attach to the user for still photography.

U.S. Pat. No. 5,081,478 to Hayashida et al is a tool which attaches to the camera for holding or for carrying purposes which tucks under the camera for compact storage or use as a tripod. In certain instances this device cannot be stored compactly or thinly in the camera bottom portion and it cannot be used as a carrying handle.

U.S. Pat. No. 5,098,182 to Brown is a complicated and cumbersome support system used to stabilize camera equipment for unwanted motions. There are two "struts" which extend from the base support making the device difficult to hold or balance, especially due to the counterbalancing by a secondary view finding device and batteries at the bottom of the first strut.

U.S. Pat. No. 5,128,701 to Hampton is a device having a platform to hold a small video camcorder which provides stabilization for photography by extending the platform to the shoulder. There is no handle to steady the device, only finger grips on each side with which to hold the device causing the user's fingers to be cramped in a bent position to support and steady the camera.

U.S. Pat. No. 5,742,859 to Acker is a support device for stabilizing a camera, particularly a video camera. It has many attachments, struts, pivoting joints with upper yoke, lower yoke, straps for use which make it cumbersome and complicated, especially when the extension pole is introduced for lifting and tilting the camera over and above the user's shoulders or as use of a monopod.

U.S. Pat. No. 5,749,011 to Nicolaci is a stabilizing rod to attach to the bottom of a video camera to steady the picture image. This device would be uncomfortable for use especially for long periods of video taping as well as having inherent personal protection flaws for designing and suggesting this device can be placed against the face and neck.

UK Pat. No. 2,103,379 is a device designed for use of two cameras which are of the still type for simultaneous use. The advantage would be that the user could use two types of film, e.g., black and white for one with color for the other, or slow film for one and fast for the other. The other advantage of this device is that twice the number of exposures can be made per second in an action sequence thus describing the still, 35 mm type camera and is not practical for video cameras.

Japan Pat No. JP403132632 is a device which attaches itself to a video camera serving as a handle with an electronically connected remote control at the bottom of the handle which can also be attached to a tripod. This device will do nothing for stabilization of the picture as one would not have differing results by holding the camera with his hand. The hand is still doing the holding for the only support with the resulting jitter and unwanted movements of the hand.

Consequently a need exists for a camcorder stabilizing platform and camcorder design which addresses the problems of previous designs.

SUMMARY OF THE INVENTION

To address the problems of prior stabilizing mechanisms, the present invention includes a stabilizing platform which attaches to the bottom of a small hand held digital or DVD camcorder with still camera capabilities to steady the filming of subjects. The platform includes a two piece bar that is held together with a locking bolt and includes a mounting screw which attaches the camera to the top of the platform. A handle is attached below the platform. The handle has a locking pin to firmly lock the handle in position on the platform. Fiber optics are incorporated into the body of the platform which are used to send infrared remote control signals to the infrared receiving port in the front of the camcorder. Alternatively a fiber optic tape is applied to the camcorder to direct the infrared signal from the handle to the infrared receiving port on the front of the camera. Further alternatively a secondary infrared port is positioned on the bottom, side or the back of the camera so that the user may be behind or to the side of the camera and able to operate the on, off, stop, zoom in, zoom out, record, pause as well as other functions of the camera. Fiber optic control allows for smooth transitions of the operations of the camera eliminating the jittery motions when manually performing these functions.

It is an objective of this invention to provide a steady and stable support for a camcorder, hand held camcorder, digital hand held camcorder with still camera features or DVD digital hand held camcorder with still camera features. The support facilitates steady recording and then viewing from either the viewfinder or the liquid crystal display screen of the subject thus eliminating the up and down or jittery motion commonly encountered during video recording.

It is also an objective of this invention to provide steady operation and control of the functions of the camcorder with the use of fiber optics. The invention includes fiber optics either imbedded in the platform or in a tape applied directly to a surface of the camcorder for sending signals from the handle to the receiving port in front of camcorder, thereby allowing the use of the infrared remote control from below the camcorder when the user is videoing from behind the camera. The infrared remote control operations eliminates the manual operations such as on, off, zooming in and out, record, pause operations which cause the unsteadiness and up and down motion by manual use. The remote control device is an accessory to all camcorders on the market today, however, the user must be in front of the camera in order to use the infrared remote control which means the user must interject himself into the picture when using the infrared remote control. Consequently the present invention eliminates this problem.

The objectives of the present invention are accomplished by a stabilizing platform which attaches to the underside of the camcorder body and extends to the shoulder of the user for support. The platform includes a two piece bar that is held together with a locking bolt and includes a mounting screw which attaches the camera to the top of the platform and also attaches the handle below the platform. The handle extends from the bottom of the platform and allows the user to hold the handle keeping the unit steady. Within the handle there is a location to attach an infrared remote control device with a double sided Velcro strip. The handle can accommodate all remote control units. The handle also has a locking pin which allows the handle to be firmly locked into position on the platform. Firmly locking the handle in place prevents the handle from moving and assuring that the remote control can direct the infrared signal into the fiber optics through the fiber optic port on the platform.

It is a further objective of this invention to incorporate the infrared remote control unit into the interior of the handle. Another feature of this invention is the elimination of camera operation delay caused by manual operation of the control buttons.

It is a further objective of this invention to provide fiber optics imbedded in the stabilizing platform to send infrared remote control signals from the handle directly into the body of the camera situated above through a secondary infrared receiving port which would be located on the bottom of the camera, just below the handle.

It is a further objective of this invention to provide a fiber optic tape to be applied directly on a surface of the camcorder to direct the infrared signals from the remote control to the infrared signals from the remote control to the infrared receiving port located on the front of the camcorder.

It is another objective of the stabilizing platform to be flexible as it may be adjusted to the user's close up vision as needed. After use, it may be folded into a compact position by loosening the locking knob, removing the handle (with attached remote control) and placing both items into a camera carrying case.

It is further an objective of this invention to provide a lightweight support, easily manufactured with minimal cost to be produced on a mass production basis.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 1 through 4, a stabilizer platform 10 of the present invention is shown. The stabilizer platform 10 is for use with a handheld camcorder and comprises a bar 12 and a handle 14. The bar 12 preferably comprises a first section 16 and a second section 18 rotatably connected together by a locking screw 20, which passes through holes 22 and 24 extending through first section 16 and second section 18, respectively. As shown in FIG. 3, hole 24 can be one of a number of holes positioned in second section 18 so that the overall length of bar 12 in the extended position can vary, depending upon the specific user utilizing the invention. A foam pad 26 is positioned on an end 28 of second section 18 opposite from holes 24. Preferably end 28 is bent slightly downwardly and includes pad 26 to rest comfortably on the shoulder of the camera user.

Preferably hole 22 has a square geometry extending at least part way through the width of first section 16 to accommodate the square section 30 on locking screw 20 beneath head 32. Locking screw 20, as previously indicated, passes through holes 22 and 24 and into locking knob 34, which threads onto locking screw 20 and rigidly locks first and second section in its fully extended position. Locking knob 34 is shown as having three flanges 36a, 36b and 36c, which facilitate tightening the locking knob onto locking screw 20 by rotation with the fingers of the user. Although shown with three flanges, locking knob 34 can be other types of knobs commercially available, such circular knobs or any other type of fastening means. As will be discussed in more detail herein, locking screw 20 and locking knob 34 also secure first section 16 and second section of the stabilizer bar 12 in a stowed position.

Positioned on the upper surface of the first section 16 of the stabilizer bar are camera pads 38a and 38b, which preferably are made of foam rubber and include a pressure-sensitive adhesive to keep the camera pads in position on the upper surface of the first section. Camera pads 38a and 38b provide a cushion and friction attachment point for the video camera on the upper surface of the first section. First section 16 further includes a fiber optics port 40, which essentially is a hole extending through the first section. First section 16 also includes a camera hole 42 extending through the section for receipt of a camera screw 44, which is used to attach the handle 14 below the first section, as well as the video camera 46 to the upper surf
