A clamping device of a static umbrella (e.g. the frame of a garden or beach umbrella) has a segment which is flexibly connected to a bush which surrounds an umbrella stick. A handle rotatably mounted in a boss attached to the bush is able to overcome the natural springiness of the segment to move it towards the umbrella stick so that a clamping cheek of the segment holds the umbrella stick in position relative to a base tube. With this construction, the device need have no longitudinal split, which would expose the mechanism to the effects of the weather, and the mechanism is enclosed, thereby preventing the umbrella stick or users from being hurt on the sharp corners and edges of the mechanism. |
