DE102008051497A1 - Shutter releasing device for e.g. movie camera, has releasing bolts compressed on releaser of camera by flexible connection between electrical drive and releasing mechanism by mechanical force transfer to release shutter - Google Patents

Abstract

The device has release bolts compressed on a releaser of a camera by a flexible connection between an electrical drive e.g. electric motor (M1) and electromagnet, and a releasing mechanism by mechanical force transfer. The release bolts release a shutter, and the flexible connection between the electrical drive and the releasing mechanism is made by a flexible band. An electronic circuit of the device permits the motor to control the release bolts per radio remote control. Electrical connections of the device connect peripheral equipments.

Description

 Universal release device for photo and film cameras

The The invention relates to a device according to the preamble of the claim.

Herewith it should be made possible, even with cheaper cameras a remote or interval controlled shutter release to allow and almost every camera and camera type to operate via radio remote control.

Various Photo and film cameras have a built-in or connectable option to remotely or to trigger interval-controlled. The great majority However, the cameras on the market is for such Usage not provided and therefore also have no connection possibility of a corresponding remote control unit.

There the ability to remotely control a camera a distance up to 100 meters to trigger, many new Motives and applications opens up, this device also for the non-professional amateur photographer very much Interesting.

The Robust and technically simple construction contributes to this At that, this device is also priced for many hobbyists will be interesting.

State of the art

remote controls are available for different camera types, condition is however, each one that these camera types for a remote release are prepared and installed an appropriate electronics or have a wired remote connection. This only applies to the high-quality SLR and bridge cameras to, the vast majority of digital consumer cameras however, does not have this option.

To compensate for this deficiency, various devices have already been invented, which exert a mechanical pressure on the camera release by means of a linkage and thus enable an indirect release of the shutter. See also the following applications. JP 10166001 . JP 63183517 . US 687297-91 . US 418307-82 . US 980261-92 . DE 9105750 . DE 8907395

in this connection These are devices that work with the camera mechanically be connected and by means of a linkage either by Cable release or rack the camera trigger actuate.

To the disadvantages of these devices is the relative rigid and inflexible connection between camera and triggering device, because of a specific design and size of the camera is required and the camera also has a tripod socket to attach the mounting linkage.

Therefore The triggering device is not variable to any Camera mount, but only supports a specific Camera type or a specific camera brand.

novelty

task The invention is one of each type of camera as possible and triggering device adaptable to any size camera to create a variable and from the position of the camera shutter button independent remote release of the camera shutter allows. Here, emphasis is placed on that as well Cameras that do not have a tripod thread can be attached. It should also be the possibility be created, any camera radio-controlled, interval-controlled or by connecting other actuators, such. B. a steering wheel switch or a foot or mouth switch for physically handicapped persons, even if the camera is not for a remote release is provided.

An embodiment of the invention is shown in the drawing as I and will be described in more detail below. at II you can see the detailed view of an exemplary release mechanism.

The great advantage of this invention is the use of a cable or a flexible band for the transmission of power from the electric motor to the Shutter release button that operates the camera shutter release button. This makes it easy to rotate or move the boom arms (A1 / A2 / A3) in multiple axes to reach each trigger position of the camera as possible, as the cable automatically lengthens or shortens to compensate for differences in length dynamically.

If a trip pulse is generated either by the radio remote control, the internal interval timer or an externally connected device, the electric motor (M1) is started for a certain time. Due to the rotation of the electric motor, a cable pull (S1) is wound onto the motor shaft and thereby pulls over two deflection rollers on the trigger mechanism ( II ). This is thereby set in rotation and thus presses on a mounted on the circumference slope an internally guided bolt out of the housing and thus on the underlying release button of a camera. If the tripping time has expired, the power supply to the electric motor is interrupted, this relaxes the cable, whereby the trigger mechanism is rotated back by means of a spring and thus exerts no pressure on the release bolt. By turning back the trigger mechanism only as much of the cable is rolled up again, that is tightened again at the next release.

The to be triggered camera is either by means of a thumbscrew on a tripod socket in the camera, over a clamping device (E1 / E2) or by means of a Velcro strip with the Attached mounting rail (D1). The clamping device fixed the camera slipping and vibration free between two Foam rubber pad and is adjustable in the clamping height.

in the Housing (C1) is located next to the battery and the control electronics an electric motor (M1), either by means of a transmission, a plurality of pulleys in the form of a pulley or directly wound on the motor shaft Moves a cable (S1) or a flexible band that moves through Deflection pulleys guided by the release arm rubber-buffered release bolt (B1) shifts by approx. 5 mm and presses it on the camera shutter. Since the length of the cable automatically by more or less windings regulated on the motor shaft is one in the Frame of the design conditions stepless position adjustment of the release bolt (B1) in horizontal, vertical and radial direction possible.

The Use of a directly rolled up cable allows it that the cantilever arms are free to move and rotate and thus every position of the camera release button can be reached can, even if this at the front or the back of the Camera is located or arranged obliquely to the camera axis is.

application areas

To the fields of application of this invention include the Radio remote control of the camera shutter primarily Intervalaufnahmen in variably adjustable intervals, so z. B. the progress document the flowering of a plant. By the However, connection of other peripherals is also the camera release by foot switch possible if z. B. the hands can not be used or this for others Purposes are needed.

• • die Tierfotografie, wenn die Anwesenheit des Fotografen eine direkte Beobachtung verhindern würde (Kamera auf einem Stativ, Fotograf bis zu 100 m entfernt)
• • die unbeaufsichtigte fotografische Beobachtung von biologischen und technischen Abläufen in wiederkehrenden Zeitabständen
• • die computergestützte Zeitrafferdokumentation durch Aneinanderreihung von vielen Einzelaufnahmen
• • Gruppenaufnahmen mit Selbstbeteiligung, da nicht wie bei einem üblichen Infrarotauslöser der Sender direkt auf den Empfänger gerichtet werden muss, sondern sich diskret in der Faust befinden kann
• • diskrete erotische Fotografie (Kamera befindet sich auf einem Stativ und wird per Funkfernsteuerung ausgelöst, womit sich die Anwesenheit einer weiteren Person erübrigt)
• • Studiofotografie, der Fotograf befindet sich entfernt von der Kamera beim Motiv

Application areas would be z. B.

• • wildlife photography if the photographer's presence would prevent direct observation (camera on a tripod, photographer up to 100 m away)
• • the unattended photographic observation of biological and technical processes at recurring intervals
• • the computer-aided time-lapse documentation by stringing together many individual shots
• • Self-participation group photography, as it is not necessary to aim the transmitter directly at the receiver, as with a standard infrared trigger, but rather discreetly in the fist
• • discrete erotic photography (the camera is on a tripod and is triggered by radio remote control, which eliminates the need for another person)
• • Studio photography, the photographer is away from the camera at the subject

To the Part of the actions within these application areas are unattended Condition, partly in the wild, instead of what the use excludes high quality equipment and thus the connectivity Priced by reasonably priced cameras, what through this universally usable triggering device allows becomes.
