Description

The present invention relates to, for example, a clamping device for attaching a glass panel to a panel holder or a support structure, and a panel tilt adjusting system using the clamping device.

More and more handrails these days use glass panels. The glass panel becomes self-supporting by inserting the lower end into the panel holder. When a person leans against the panel, the force acting on the panel holder is greater than that of the lever, and the panel itself is quite heavy, so the panel must be firmly fixed to the panel holder.

As a conventional panel support structure, a panel support structure is known in which a wedge is driven into a gap between a panel surface and a support surface of a panel holder to firmly fix the panel to the panel holder (see Patent Document 1).
