Description

尤其用于摄像的单脚架支承件流体阻尼
技术领域
本发明涉及一种设计成尤其用于摄像的单脚架支承件，从而基本上减少通常手动摄像的摇晃。
背景技术
当用手持式摄像机和类似机器实施摄像时，不可避免的是，它会经受沿着三维空间的三根轴线的摇晃。为此，强烈推荐使用支承件，该支承件用来通过减少这种摇晃以提高摄像质量。在这些支承件中，具有三脚架结构的支承件最佳地保证了图像稳定性。然而，三脚架支承件有着体积庞大且笨重的不可避免的缺点，而在所谓的单脚架中，体积庞大且笨重会大大缓和，在单脚架中，摄像装置安装在杆的顶部，该杆通常是可伸缩调整的且其相对端搁置在地面上。可减小在包含杆的轴线的垂直平面中且围绕目标光学轴线的摆动角度，因为这些摆动角度与摆动支点有关，在这种情况下该摆动支点远离该装置而在单脚架所搁置在地面(底面)上的点处。这能够显著减少绕相应轴线的摆动。
另一方面，沿着所谓全景轴线、绕单脚架的杆的轴线的摆动保持基本不变。上述令人讨厌的摇晃因此持续这种运动。为此，单脚架支承件迄今已经在一定程度上用在静态摄影领域，但是它们还没有在摄像领域获得一样的成功。
发明内容
本发明的目的是提供一种单脚架支承件，该单脚架支承件在结构和功能上设计成可避免关于提及的现有技术所述的所有缺点。
该目的通过本发明借助根据下面的权利要求书所生产的单脚架支承件来实现。
附图说明
从参照附图借助非限制性例子来说明的一较佳但非排它性实施例的详细描述中，本发明的特征和优点将会更加清楚地显现出来，在附图中：
-图1是根据本发明的单脚架支承件的立体图；
-图2是图1的支承件的细节的纵剖面图；
-图3是前面附图的支承件的细节的放大比例的示意剖视图。
具体实施方式
在图1中，附图标记1总的表示尤其用于摄像的单脚架支承件，该单脚架支承件包括由多个杆元件2a、b、c、d形成的伸缩杆2，这些杆元件可彼此内外地伸缩滑动且可以本身已知的方式相对于彼此锁定，从而根据需要改变杆2的延伸长度。用于摄像装置5的基座3和附连件4设置在杆2的相应纵向相对端。基座3用作地面上用于支承的承座，且包括横向构件6，至少一个且较佳地三个附件7延伸自该横向构件6，这些附件7铰接至横向构件，从而它们可以绕相应的销8枢转，借助弹性突舌9以可释放的方式临时碰锁到基本沿着径向相对于横向构件延伸以形成三脚架支座的工作位置，或者碰锁到靠近杆2的闲置位置，这些弹性突舌9从附件7的茎杆上局部地切割出来，并且在其端部具有销10，该销10咬合在横向构件6的对应凹处11a、b中。甚至设置单个附件就能通过用脚压在附件7上而使单脚架支承件锁定在地面上，从而获得比简单地搁置在地面上的单脚架支承件明显更加稳定的固定。
基座3还包括具有球窝接头13的铰接件12，该铰接件介于横向构件6和杆2之间，杆2可借助该铰接件相对于基座3定向。接头13借助其柄部连接至杯状构件14，杆2的下端通过插入套管15而配合在该杯状构件14中。间隙15a形成在杯状构件14和与杯状构件14共轴的套管15之间，且由O形圈密封件15b以气密的方式封闭且充填有粘性流体，从而形成具有粘性联接的减震元件，诸如Cartoni的美国专利US 4,899,854中所述。由于保持在间隙15a中的粘性流体，这种减震元件可确保：套管15相对于杯状构件14的转动涉及粘性流体的输送，因此可阻尼相关振动现象。尽管这种减震元件被认为是较佳的，但是应该理解，可以用摩擦减震器或其它类型的减震器来替换它。
可以设想，所有的杆元件2a-d应该是刚性的，但是也可假设，第一杆元件2a应该通过插入铰接件而铰接在两个部分16、17中，该铰接件包括第一叉状元件18，该第一叉状元件18以可绕横向于杆2的轴线枢转的方式铰接至第二铰接元件19。在叉的一侧上，平衡弹簧20插在铰接元件18、19之间，该平衡弹簧20趋于将两个铰接元件保持在相对位置中，从而杆元件2a的两个部分16、17基本彼此对准，在叉的另一侧上，粘性联接21用作对于在铰接元件的相对枢转中的任何摇晃和/或振动的阻尼器。这种本身已知的粘性联接是在美国专利US 4,899,854中描述的类型。
在使用中，单脚架支承件延伸至所想要的长度，摄像机配装至附连件5，且基座打开从而所有三个附件7相对于横向构件6径向延伸。
由于球窝接头铰接件的作用，可允许杆相对于基座的向下倾斜和向上倾斜的定位和运动以及侧向的摆动。如上所述，由于摆动中心和摄像机的距离，这些运动不会引起任何明显的振动现象，当单脚架搁置在倾斜的地面上而寻找垂直位置时，这些运动是不可避免的。
然而，绕与杆2的轴线基本重合的所谓全景轴线的转动可由具有粘性联接的减震元件来阻尼，该元件插在杆和基座之间，但该元件的摩擦力小于由球窝接头铰接件提供的阻力。结果，即使支承件是单脚架型，摄像机沿所述三个轴线的运动也不会产生明显的振动作用。
本发明的另外优点包括体积小、重量适度、容易定位且稳定性好，这是通过在单脚架的基座上的附件来进一步改进的。
