Description
Die Neuerung betrifft dreibeinige Stative für die Halterung von Kameras und anderen Geräten, z.B. optischen Meßgeräten, die einen festen, schwingungsfreien Stand erfordern.The innovation concerns tripods for holding cameras and other devices, e.g. optical measuring devices, which require a firm, vibration-free stand.
Stative herkömmlicher Bauart nehmen Kameras oder andere Geräte, z.B. optische Meßgeräte auf Schwenkköpfen oder Kugelköpfen auf. Jede Auslösung oder äußere Anregung versetzt das elastische System GERÄT-STATIV in Schwingungen, die z.B. bei Kameras zu Bewegungsunschärfen im Ergebnis führen.Conventional tripods hold cameras or other devices, e.g. optical measuring devices, on swivel heads or ball heads. Every triggering or external stimulation causes the elastic DEVICE-TRIPOD system to vibrate, which, for example, leads to motion blur in the result of cameras.
Dieses unangenehme Verhalten macht sich besonders bei Freilandaufnahmen mit Kameras mit langbrennweitigen Objektiven bemerkbar, wo z.B. der Wind Schwingungen induziert, die zu nicht zufriedenstellenden Ergebnissen führen.This unpleasant behavior is particularly noticeable when taking photos outdoors with cameras with long focal length lenses, where, for example, the wind induces vibrations that lead to unsatisfactory results.
Man hat durch Entwicklung besonders massiver und sehr teurer Stative versucht, diese Wirkung zu beseitigen. Letzten Endes bleibt jedoch das System KAMERA-STATIV ein elastisches Schwingungsgebilde, das durch aufwendige Konstruktion nur bis zu einem gewissen Grade gedämpft werden kann.Attempts have been made to eliminate this effect by developing particularly solid and very expensive tripods. Ultimately, however, the CAMERA-TRIPOD system remains an elastic vibration structure that can only be dampened to a certain extent by complex construction.
Es werden bereits zusätzliche feste Stützen zwischen Stativfuß und Kamera von Stativherstellern angeboten. Sie schränken jedoch die Bewegungsfreiheit z.B. bei der Einstellung einer Kamera ein und wirken nicht als Schwingungstilger, sondern blockieren die Kamera nur in einer Schwingrichtung, ohne wirksame Dämpfungskräfte in allen Bewegungsrichtungen zu erzeugen. Tripod manufacturers already offer additional fixed supports between the tripod base and the camera. However, they limit freedom of movement, e.g. when adjusting a camera, and do not act as vibration dampers, but rather block the camera in only one direction of vibration without generating effective damping forces in all directions of movement.
Aufgabe der Neuerung ist es, auch bei weniger aufwendigen Stativen Schwingungen z.B. der Kamera bei Auslösung und bei äußerer Schwingungsanregung zu vermeiden.The aim of the innovation is to avoid vibrations, e.g. of the camera when triggered and when subjected to external vibrations, even with less complex tripods.
Diese Aufgabe wird in der Weise gelöst, wie sie in den Schutzansprüchen 1 bis 5 angegeben ist.This problem is solved in the manner set out in claims 1 to 5.
Die schwingungsdämpfenden Elemente stellen eine zusätzliche unmittelbare Verbindung zwischen Stativfuß und der Kamera oder dem Gerät, z.B. optischem Meßgerät, dar und vermeiden durch Reibungsdämpfung deren Schwingung. Solche schwingungsdämpfenden Elemente haben sich bereits in der Praxis bewährt. Selbst bei stürmischem Wetter und schlechten Lichtverhältnissen wurden bei Einsatz langbrennweitiger Objektive einwandfreie fotografische Ergebnisse erzielt.The vibration-damping elements represent an additional direct connection between the tripod base and the camera or device, e.g. optical measuring device, and prevent vibration by dampening the friction. Such vibration-damping elements have already proven their worth in practice. Even in stormy weather and poor lighting conditions, flawless photographic results have been achieved when using long focal length lenses.
Bei den schwingungsdämpfenden Elementen kann es sich z.B. um Teleskopbeine mit gegeneinander reibenden Zylindern oder um andere Schwingungsenergie vernichtende Dämpferelemente handeln.(z.B. Gestänge mit unterschiedlichen Querschnitten, die gegeneinander reiben.)The vibration-damping elements can be, for example, telescopic legs with cylinders rubbing against each other or other damping elements that dissipate vibration energy (e.g. rods with different cross-sections that rub against each other).
Anhand FIG.1 bis FIG.5Based on FIG.1 to FIG.5
soll die neuerungsgemäße Einrichtung am Beispiel eines handelsüblichen Kamerastatives beschrieben werden.The new setup will be described using the example of a commercially available camera tripod.
FiG. 1: An zwei der drei Beine eines Statives (3) sind die schwingungsdämpfenden Elemente in Form von Teleskopbeinen (5) unten allseits beweglich spielfrei angebrachte). Die Zylinder dieser Teleskopbeine (5) sind so ausgeführt, daß sie gegeneinander reiben und somit wie Reibungsdämpfer wirken. Die beiden Teleskopbeine (5) sind oben miteinander verbunden und besitzen dort eine ebenso frei bewegliche Verbindung z.B. Kugelkopf (6) zur Kamerad ),deren Objektiv (2) auf dem Schwenkkopf oder Kugelkopf des Stativs(3) befestigt ist.Fig. 1: On two of the three legs of a tripod (3), the vibration-damping elements in the form of telescopic legs (5) are attached to the bottom so that they can move freely on all sides without play. The cylinders of these telescopic legs (5) are designed so that they rub against each other and thus act as friction dampers. The two telescopic legs (5) are connected to each other at the top and have a connection there that is also freely movable, e.g. ball head (6) to the camera, whose lens (2) is attached to the swivel head or ball head of the tripod (3).
Die Befestigung der unteren Teleskopbeingeienke (4) am Stativ {3) geschieht über örtlich fest montierte Klemm-oder Schraubverbindungen.(7)The lower telescopic leg joints (4) are attached to the tripod {3) using locally mounted clamp or screw connections.(7)
FIG.2 und 3: Die nach allen Seiten bewegliche Anbringung (4) und die Reibungszylinder der Teleskopbeine (5) gewährleisten eine problemlose Bewegung der Kamera (1) nach oben, nach unten und in seitlicher Richtung.FIG.2 and 3: The omnidirectional mounting (4) and the friction cylinders of the telescopic legs (5) ensure smooth movement of the camera (1) up, down and sideways.
Da jedoch die Reibungskräfte der Teleskopbeine (5) größer sind als die durch zugeführte Schwingungsenergie erzeugten Schwingkräfte, werden Schwingbewegungen unterdrückt.However, since the friction forces of the telescopic legs (5) are greater than the oscillation forces generated by the supplied oscillation energy, oscillation movements are suppressed.
FIG.4 Es können auch Schwingungen an nicht überkragenden z.b. optischen Geräten (1) unterdrückt werden, wenn sie auf Schienen (9) montiert werden, die ihrerseits mit der Schwingungsdämpfungseinrichtung (4 bis 6) verbunden werden.FIG.4 Vibrations on non-overhanging devices (e.g. optical devices) (1) can also be suppressed if they are mounted on rails (9) which in turn are connected to the vibration damping device (4 to 6).
FlG.5: Bei Nichtbenutzung und beim Transport können die Teleskopbeine (5) am Stativ (3) mittels Klemm- oder Schraubverbindung befestigt werden (8)FlG.5: When not in use and during transport, the telescopic legs (5) can be attached to the tripod (3) using a clamp or screw connection (8)
