Title:
CLAMP DEVICE FOR CONNECTION
Document Type and Number:
WIPO Patent Application WO/2005/100841
Kind Code:
A1
Abstract:
A clamp device (1) for connection, comprising a terminated annular strap band (3) installed so as to wind around a connection part (2) by displacing to reduce the diameter thereof. An auxiliary strap part (4) is so formed that one end part is fixedly connected to the inner surface part of the one end part of the strap band (3) and insert ports (5) for inserting the other end part of the strap band (3) therethrough are opened at the other end part. The strap band (3) is displaced to reduce the diameter thereof by the rotating operation of a screw member (6) to tighten it on the connection part (2) with a specified tightening force. Also, the thickness dimension (T) of the portion of the strap band (3) fitted to a guide start end part (3A) is set larger than the thickness dimension (t) of the other portion. Thus, even if a torsional rigidity is increased and a large tightening force is required, material cost can be saved, and the auxiliary strap part (4) and the strap band (3) can be protected against torsional deformation at an advantageous cost.
