It should be noted that while the battery pack 10 is illustrated as being of the pack type, the present invention is not limited to this type of power source and a case type arrangement into which cell type batteries can be loaded, can be used as desired.
The carrying handle 20 which characterizes the present invention is shown in FIGS. 1-3. In this instance the handle is essentially C-shaped and comprises a horizontal base portion 20a, a vertically extending portion 20b and a grip portion 20c. The base portion 20a is formed with a centrally located recess 20d in which an elongate slot 20e is defined. A slide plate 21 is disposed in the recess 20d and arranged to be reciprocally movable back and forth therealong. A screw 22 of the type provided on a camera mounting tripod is disposed through the slide plate 21 and arranged to be threadedly received in a threaded tripod connection bore 8. The slide plate is further formed with a pin 23 which extends up from the upper surface of the plate and which is receivable in a positioning bore 9 formed in the bottom of the camera body 2 proximate the threaded bore 8.
The vertically extending portion 20b is formed with an elongate opening 20f in which a battery connection plate 24 is reciprocally received. As indicated in FIG. 1 this connection plate 24 is arranged so that it can be moved up and down along the slot 20f. The front or inner face of the connection plate 24 is formed with L-shaped recesses 24a, 24a and 24b, 24b which are adapted to engagingly receive the projections 6a, 6a and 6b, 6b formed on the mounting flanges 2a, 2b. The front face is further formed with spring plate type contacts 26, 26 which are engageable with the pin type contacts 7, 7 which extend from the battery mounting site 6 formed on the rear of the camera 1.
The rear or outer face of the connection plate 24 is formed with a battery mounting site 25 which is constructed and arranged in exactly the same manner as the battery mounting site 6 formed on the camera body 2. That is to say, the mounting plate 24 includes mounting flanges 24c, 24d which are provided with L shaped projections 25a, 25a and 25b, 25b, and pin type contacts 27, 27.
When the battery pack 10 is mounted on the mounting site 25, the projections 25a, 25a and 25b, 25i b engage in the recesses 11a, 11a and 11b, 11b in the same manner as when the battery pack 10 is mounted on the camera body 2. In order for electrical connection between the battery and the camera to be established, the pin type contacts 27, 27 formed on the mounting site 25 and which engage with the spring plate type contacts 12, 12 of the battery, are electrically connected with the spring plate type contacts 26, 26 formed on the connection plate 24.

With this arrangement electrical power from the battery pack 10 can be supplied to both the camera and the accessory hot shoes 28, 29 (see FIG. 6).
In this embodiment the accessory hot shoe 28 is illustrated as being used to mount a video light 30. The accessory hot shoe 29 can be used to mount a microphone or the like. A switch 32 provided on the lamp body enables the light to be switched on and off as desired.
With the above described embodiment, when it is desired to use the carrying handle, first the battery pack 10 is detected from the mounting site 6 formed in the camera body 2 in the manner indicated in FIG. 4. Following this, the carrying handle 20 is placed in position on the camera with the connection plate 24 in a raised position and so that the projections 6a, 6a and 6b, 6b are engaged in the recesses 24a, 24a and 24b, 24b and so that a suitable clearance is provided between the bottom of the camera 1 and the horizontally extending base portion 20a.
Next, the slide plate 21 is moved to a position wherein the guide pin 23 is aligned with the guide bore 9. The handle 20 is then moved upwardly with respect to the camera body 2 so that the horizontally extending base portion approaches the bottom edge of the camera and the pin 23 enters the bore 9. After this the screw 22 is threaded into the bore 8 in a manner which secures the handle 20 and the camera body 2 together. The battery 10 is subsequently mounted on the mounting site 25 in a manner wherein the projections 25a, 25a and 25b, 25b are engaged in the recesses 11a, 11a and 11b, 11b formed at the corners of the battery unit 10.
Under these conditions the pin type contacts 27, 27 are in electrical contact with the spring plate type contacts 12, 12 of the battery, and the pin type contacts 7, 7 on the mounting site 6 are in electrical contact with the spring plate type contacts 26, 25 on the mounting plate 24. Accordingly, electrical connection between the battery pack 10 and the camera 1 and between the battery pack 10 and the accessory shoes 28 and 29, are respectively established.
Thus, as will be appreciated, with the present invention it is possible to connect a carrying handle to video cameras of the type wherein a battery pack mounting site is provided at the rear of the camera body 2 without the need for the special provision of carrying handle connections per se.
Further, as the carrying handle is provided with a battery mounting site 25 and is arranged so that horizontally extending base portion is adapted so that is can make use of the tripod connection arrangement, it can be connected easily and subsequently used to carry the battery pack 10. In addition, the design is such that the grip portion 20c of the handle extends above the camera, does not get in the way during use and additionally serves the mount accessories such as lights, microphones, etc.
Further, the carrying handle according to the present invention can be connected in a manner wherein it compactly fits about the camera in a manner which appears to be integral therewith, which does not require special connections to be provided and which does not detract from the design/appearance of the camera.
While the above embodiment has been disclosed in a manner wherein the battery pack 10 is connectable to the battery mounting site 25, it is within the scope of the present invention to form the battery pack/case in a manner so that it is integral with the carrying handle.
