Definitions

  • the invention relates to a holding device of a photographic and / or cinematographic device, which has at least one support tube designed as a carbon fiber tube.
  • Such a holding device is known from practice. It can be, for example, a one- or three-legged tripod, each individual leg consisting of at least one tube forming a support tube and, as a rule, can be pulled out once or twice.
  • the stand can additionally or alternatively have a height-adjustable, vertically aligned center tube forming a support tube, at the upper end of which fastening means for a photographic and / or cinematographic device, e.g. for a camera or a headlight.
  • the holding device of the type mentioned in the introduction can also be, for example, a shoulder carrying device, a pedestal or a tripod which is provided with a support tube for camera accessories, such as a compendium or a filter.
  • a support tube can, for example, be clamped at one end under a plate on which a camera is attached and connected at the other end to the relevant accessory.
  • Support tubes of the aforementioned type are usually made either of metal, then mostly of aluminum, or of a carbon fiber material. Carbon fiber offers considerable weight advantages over aluminum.
  • DE 42 14 858 Cl describes a carrying device for a component which is made of fiber-reinforced plastic.
  • the carrying device can have a C-arm for carrying an X-ray emitter of an X-ray diagnostic device.
  • a molded body made of synthetic foam which determines the shape of the C-arm. This molded body is surrounded with fiber-reinforced plastic, which takes over the wearing properties.
  • the invention is based on the object of creating a holding device of the type mentioned in the introduction, which is lighter than known holding devices and which can be produced inexpensively.
  • a holding device of a photographic and / or cinematographic device which has at least one support tube designed as a carbon fiber tube, which is at least partially foamed with rigid foam.
  • the essence of the invention therefore lies in the fact that a carbon fiber tube serving as a support tube of a holding device of a photographic and / or cinematographic device is given such high stability by the foaming with rigid foam that a small wall thickness of the carbon fiber tube is sufficient and that a diagonal winding of the carbon fiber tube can be dispensed with.
  • the rigid foam can be introduced in a known manner, depending on the desired nature, without pressure or under pressure.
  • the person skilled in the art can optionally also use structure-forming material, such as e.g. Glass fiber in which hard foam is provided.
  • the holding device itself can also be given a sufficiently high stability.
  • rigid foam is an inexpensive and easy to process material with a low specific density.
  • a carbon fiber Pipe in the sense of the invention can therefore be produced in a simple manner and therefore also inexpensively. This in turn leads to an inexpensive holding device in the sense of the preamble of patent claim 1.
  • a holding device which is reduced in weight compared to the prior art can also be produced in this way.
  • the holding device according to the invention also offers significant weight advantages.
  • the support tube of the holding device according to the invention does not necessarily have to have a circular cross section. Rather, it can also be a hollow profile with a rectangular, square or any other cross section, the cavity of which is foamed with rigid foam. A structure such as a honeycomb profile can be provided in the cavity, which is foamed with hard foam.
  • the holding device in the sense of the invention can be a holding device e.g. for cameras, lighting devices or also for accessories, such as a compendium dealing with the photo / film sector, whereby it is particularly suitable for heavier film cameras.
  • holding device used here is to be understood in its broadest sense in any case. It extends, among other things, to tripods, pedestals, shoulder-carrying devices and dollys and spiders. If the holding device is a tripod, that is to say an adjustable holding device for optical devices, laboratory devices or the like, the support tube can, for example, either be part of an optionally extendable leg of the tripod or also a height-adjustable center column on which a ball joint or also a Panoramic head is arranged for fastening, for example, a camera or a headlight. It is also conceivable that a pivot lever of a tripod head represents the support tube.
  • the subject of the invention is also the support tube alone, i.e. a support tube for a photographic and / or cinematographic device, made of a carbon fiber tube, which is at least partially foamed with rigid foam.
  • Figure 1 is a tripod tripod for a photo or film camera.
  • Fig. 2 is a section along the line II-II in Fig. 1;
  • Fig. 4 shows the upper area of a pedestal with a television camera attached to it.
  • tripod 1 shows a tripod 1 in the erected state.
  • This tripod has three legs 2A, 2B and 2C, which are pivotally attached to a mounting shell 3 for receiving a tripod head, not shown here, to which, for example, a film or photo camera, also not shown here, can be attached.
  • the legs 2A, 2B and 20 of the stand 1 are each easily extendable and consist of two mutually displaceable tube pairs 5A and 6A and 5B and 6B as well as 50 and 60 which can be fixed by means of clamping devices 4A, 4B and 40.
  • the tube pairs 5A, 5B and 50 each end in a tripod base 8A, 8B and 80 provided with a mandrel, which respectively engages in a recess 9A, 9B and 90 of a leg 10A, 10B and IOC of a bottom spider 10.
  • the tripod leg 2B is shown in cross section in FIG. 2.
  • the individual tubes of the tube pairs 5B and 6B each consist of a carbon fiber tube 11, 12, 13 and 14, respectively.
  • the wall thickness of the individual carbon fiber tubes is approximately 1.5 mm in the present case.
  • the respective cavity of the carbon fiber tubes 11, 12, 13 and 14 is filled with a rigid foam core ILA, 12A, 13A and 14A.
  • the hard foam cores 11A, 12A, 13A and 14A consist for example of polyurethane. However, any other suitable rigid foam material can also be used.
  • the other legs 2A and 20 of the stand 1 shown in FIG. 1 are constructed like the leg 2B shown in FIG. 2.
  • the wall thickness of the carbon fiber tubes can be kept low. Nevertheless, the individual tubes and thus the stand 1 according to FIG. 1 have the stability appropriate to the respective operating conditions.
  • the legs 10A, 10B and IOC of the bottom spider 2 shown in FIG. 1 can also be constructed in accordance with the tubes shown in FIG. 2.
  • the legs 10A, 10B and IOC then consist, for example, of a carbon Hollow fiber-optic profile with a square cross-section, which is filled with a rigid foam core made of polyurethane.
  • FIG. 3 shows a dolly 15 which comprises three legs 17A, 17B and 170 connected by a connecting member 16. At the ends of the legs 17A, 17B and 170 there are rollers 18A, 18B and 180 on the underside and on the top hook eyes 19A, 19B and 190 for the legs of a tripod, e.g. of the tripod shown in Fig. 1.
  • the legs 17A, 17B and 17C each consist of a carbon fiber tube which is foamed with rigid polyurethane foam analogous to the tubes shown in FIG. 2.
  • rigid polyurethane foam By foaming with rigid polyurethane foam, the wall thickness of the carbon fiber tubes can be kept low, while the tubes and thus the Dolly 3 still have a high level of stability.
  • the upper area of a pedestal 20 is shown, on which a television camera 21 is fastened via a fastening plate 22.
  • the pedestal 20 has at its upper end a swivel head 23, which is provided with swivel levers 24, and below the swivel head 23 a control wheel 25, which serves to adjust the height of the pedestal 20.
  • the camera 21 comprises a camera body 26 and a lens head 27, which is provided with a compendium 28.
  • At least one support tube 29 is arranged between the mounting plate 22 and the compendium 28 holds the compendium 28 and the lens head 27 in position.
  • the support tube is clamped, for example, on the mounting plate 22 and on the compendium 28. But it is also conceivable that the support tube 29 is screwed on one or both sides.
  • the support tube 29 is constructed in accordance with the tubes shown in FIG. 2. It therefore consists of a carbon fiber tube, which has a hard foam core, preferably made of polyurethane.
  • the polyurethane core in turn gives the support tube 29 the stability required here, even with a thin wall of the carbon fiber tube.
