Abstract:
In combination, a pair of binoculars having a pivot and a tripod attachment for attaching to the pivot of the pair of binoculars, the tripod attachment comprising:an attachment body which is attached to the tripod, the attachment body having a hole; a shaft member which is rotatably inserted through the hole of the attachment body; an end of the shaft member being fastened to the pivot of the pair of binoculars; and a friction force producing member which is adjacent to the attachment body, the friction force producing member producing a friction force when fastening the shaft member to the pivot, the friction force holding the pair of binoculars at any desired position with respect to the attachment body, the friction force allowing the pair of binoculars to rotate around the shaft member only when certain external force is applied to the pair of binoculars, wherein the friction force producing member further includes a sleeve which is inserted in the hole of the attachment body, the shaft member being inserted through the sleeve, the sleeve further including an extending part which is extended when the shaft member is inserted in the sleeve; and an engaging part engaging the pivot of the pair of binoculars so that the sleeve is rotated when the pivot rotates, wherein the friction force is produced between the extending part being extended and the hole of the attachment body.
