SUPPORT APPARATUS FOR A BODY MOUNTABLE CAMERA AND METHOD OF STABILISING SUCH A CAMERA
Field of the Invention
5 This invention relates to a camera support apparatus, in particular to an apparatus for mounting the constituent parts of a body-mounted portable movie or video camera system.
10 Background to the Invention
In the film industry there is a need for portable camera systems which can be body-mounted to a camera operator and carried round a film set by the operator.
Known body-mounted movie camera systems generally employ a harness which is worn by a camera operator, and to which is mounted the movie camera system. The movie camera system typically comprises a spring-loaded arm, attached
20 to the harness and on which, at it's free end, is mounted a pole on which the movie camera is mounted. Generally, other components of the system are also mounted on the pole by way of brackets, including battery packs, monitors and distribution boxes. Instead of mounting the camera
25 system to a harness for a camera operator, body-mounted cameras may also be mounted on a suitable vehicle such as a trolley, automobile or aircraft.
Known body-mounted camera systems generally also employ 30 stabilising apparatus, in order to maintain the camera in a prescribed orientation as the operator or vehicle moves around. Stabilising apparatus can include gyroscopes and stabilising springs. Body-mounted camera systems such as those described above have a number of disadvantages.
Prior art systems rely on mounting poles which have fixed battery holders or battery packs. The fixed battery holders and battery packs generally employ only one type of battery which has specific dimensions and weight. Many types of battery are only available in certain countries, and if a camera operator wishes to use prior art systems in countries other than that in which the system was designed, he or she must carry enough spare batteries to finish the work as it is unlikely that batteries of the same dimensions or weight will be available in other countries .
Furthermore, as each type of prior art system relies on batteries of a fixed type, if a different camera of larger or smaller size and weight is fitted to the system, the balance of the system will be compromised. The counterbalancing effect of the fixed battery may not be as effective if a larger or smaller camera is fitted, and the system may even become unstable.
It is therefore an aim of preferred embodiments of the present invention to overcome or mitigate at least some of the above-mentioned disadvantages or other disadvantages, of the prior art, whether mentioned herein or otherwise.
Summary of the Invention
According to the present invention there is provided a support apparatus for a body-mountable camera, comprising a camera mounting means comprising a battery mounting means for mounting at least one battery, and wherein the battery mounting means and the camera mounting means are movable relative to each other.

Description of the Preferred Embodiment
Referring firstly to Figure 1A, IB and 1C, a preferred embodiment of a support apparatus for a body-mounted camera comprises a camera mounting means 2 which includes a support frame 4. The support frame 4 comprises a plurality of elongate frame members 6, which are connected together by means of connection brackets 8, to form a substantially rectangular three-dimensional framework.
The connection brackets 8 include screws 10 which can be unscrewed to allow the support frame 4 to be dismantled, and reassembled, in a different shape if desired.
Each elongate frame member 6 comprises a plurality of apertures 12 which extend through the elongate members in a direction substantially perpendicular to the primary axis of the elongate member.
The support frame 4 also comprises a bracket 18 which in use is arranged to slidably receive a battery mounting means to the support frame .
The support apparatus also comprises a battery mounting means. The battery mounting means comprises a battery mounting member 16 as illustrated in Figures 3A and 3B. A mounting bracket 18 is secured to the support frame 4, in order to receive the battery mounting member 16. The mounting bracket 18 includes two clamp portions 20 which in use are clamped around adjacent and parallel elongate frame members 6, as illustrated in Figures 3A and 3B. The mounting bracket 18 also includes four elongate hollow cylinders 22 for receiving the battery mounting member 16.
The battery mounting member 16 comprises a first battery mounting portion 24 and a second portion 26 for attaching the battery mounting member 16 to the support frame 4, by way of the mounting bracket 18. The second portion 26 comprises four elongate member 28 which are arranged to be received by the four elongate hollow cylinders 22 of the mounting bracket 18.
The first portion 24 comprises a battery mounting surface 30 which includes a number of means for mounting at least one battery. The means for mounting the or each battery may include apertures 32 to receive screws or bolts, mounting surfaces 34 and the like.
Alternatively a battery retaining member 36 may be attached to the battery mounting surface 30 as shown in Figures 2A, 2B and 2C. The or each battery can be then be attached to the battery retaining member 36, as shown in Figure 5.
Use of the preferred embodiment of a support apparatus of the present invention will now be described.
Referring now to figures 4A, 4B and 5, in use a camera 38, is mounted to the support frame 4 via a camera mounting member 40, which can be clamped to the support frame in any orientation by way of a suitable clamp 42. As shown in Figure 5, the camera may be mounted on a mounting pole 39 which is connected to the camera mounting member 40. The mounting pole 39 includes an attachment member 46 for attaching the mounting pole 39 to a spring- loaded arm (not shown) which can then be attached to a harness, for attaching the camera system to the body of an operator. Alternatively, the attachment member 46 may be attached to a spring-loaded arm which is connected to a suitable vehicle. The mounting pole 39 also includes a camera monitor 48, attached via a mounting bracket 50.
A battery can then be mounted on the support frame 4 as follows. The battery is mounted on the battery mounting member 16, either by directly attaching the battery to the battery mounting portion 24 or by first attaching a battery retaining member 36 to the battery mounting portion 24, then attaching a battery to the battery retaining member 36 as shown in Figure 5.
The mounting bracket 18 is connected to the support frame 4 by clamping the two clamp portions 20 onto two parallel elongate frame members 6 of the support frame 4, as shown in Figures 1A, IB, 1C, 2A, 2B, 2C, 4A and 4B.
The battery mounting member 16 is then mounted on the mounting bracket 18. The four elongate members 28 of the battery 'mounting member 16 are inserted into the four hollow cylinders 22 of the mounting bracket 18.
Depending on the weight and orientation of the camera mounted to the support apparatus, the battery may be used as a stabilising counter-balance by adjusting the distance of the battery from the support f ame 4. Thus the battery may be moved towards or away from the support frame 4 by sliding the elongate member 28 of the battery mounting member 16 in the hollow cylinders 22 of the mounting bracket 18, to adjust the distance of the battery mounting portion 24, and hence the attached battery, from the support frame 4.
It will be appreciated by the skilled reader, that more than one battery mounting means 14 may be attached to the support frame 4 such that batteries may be mounted in multiple orientations about the support frame 4. This is especially useful if a camera is mounted which has multiple projections, or to which is attached a stabilising arm, as the weight distribution and orientation of such a camera may require more than one counterbalance, or additional weighting of the support apparatus. Also, if a camera of differing size is attached to the mounting pole 39, the battery mounting means 16 may be adjusted such that the attached batteries 52 provide a stabilising counter-balance to the new camera on the apparatus.
The support frame 4 may also include one or more additional mounted batteries which are mounted directly to the support frame 4 without the need to use a battery mounting means 18, to provide additional weighting and battery power.
The support frame 4 may also have subsidiary modules connected to it, such as a monitor, a distribution box, stabilising gyroscopes or a stabilising arm, for attachment to a vehicle or a body harness on a camera operator.
