Device for optional coupling of a stretcher with different implements

摘要: This invention concerns a device for optionally coupling stretcher with different implements permitting the releasing of from one implement and another implement, to which it is be transferred, performed simultaneously without passing an intermediate position in disconnected both implements. For this purpose characterized that has two transverse cylinders, mounted eccentric rotation so as permit vary space between cylinders by cylinder. One member cylindrical recesses its end edge portions engaged their closest position. The other fork-shaped support sides fork legs most spaced-apart position, eccentricity cylinder spacing being such when transferring engagement other, said at least partially before first entirely released.
