The electrostatic lock (ESL) relates to devices for fixing separate parts or elements of various mechanisms and devices and for keeping same in a fixed state relative to one another, with the possibility of subsequent converse disengagement thereof, and functions on the basis of an electrostatic (coulomb) attractive force between electrodes which are charged with opposite electrical charges and are separated by a sufficiently narrow layer of a dielectric. The device is intended for eliminating the vulnerability of the ESL from the smallest contaminant arising on the electrodes or on the dielectric in the electrode contact area during the operating process. To this end, the ESL is supplemented with a special blocking mechanism consisting of two main mechanically separable parts, one of which is a blockable part, and the other is a reciprocal part thereto. Furthermore, the ESL electrodes are arranged compactly on the reciprocal blocking part with the aid of a kinematic connection, which makes it possible to completely isolate the electrodes from a contaminant and from other harmful effects of the environment, which may make it impossible for the ESL to work. |
