An anchor device is provided which makes it possible to fasten various members or instruments to the wall to the back of which hands cannot reach with a bolt. The anchor device includes an inserting member molded of a synthetic resin, a nut mounted to the tip of the inserting member, and a tubular seating member mounted on the inserting member. The inserting member has a baglike portion integrally formed at the tip of an elongated trough-like trunk portion having a semicircular section through a bendable portion. The nut, which has a semicircular section, is received in the bag-like portion. The anchor device further includes an engaging means which comprises a plurality of serrations formed on both edges of the outer periphery of the trough-like trunk portion continuously in the longitudinal direction and a protrusion provided on the inner periphery of the seating member at its portion contacting both edges of the trough-like trunk portion. By inserting it into a hole formed in a wall member, it fixes an article to be fastened by use of a bolt.
An anchor device comprising an inserting member having a trough-like trunk portion and a bag-like portion provided at the tip of said trough-like trunk portion through a bendable portion, said bag-like portion extending in a direction perpendicular to the axis of said trough-like trunk portion, a nut inserted in said baglike portion and having a threaded hole in a portion protruding from said bag-like portion, a ring-shaped seating member fitted on said trough-like trunk portion, and retaining means for retaining said seating member so as not to come out of said trough-like trunk portion, said retaining means comprising a plurality of serrations formed on said trough-like trunk portion continuously in the longitudinal direction on both edges of the outer periphery of said trough-like trunk portion and a protrusion formed on the inner periphery of said seating member so as to contact with both edges of said trough-like trunk portion.
An anchor device comprising an inserting member having a trough-like trunk portion and a bag-like portion provided at the tip of said trough-like trunk portion through a bendable portion, a nut inserted in said baglike portion and having a threaded hole in a portion protruding from said bag-like portion, a seating member fitted on said trough-like trunk portion, and retaining means for retaining said seating member so as not to come out of said trough-like trunk portion, characterized in that said seating member comprises a cylindrical portion and a thin disk portion provided at one end thereof, said disk portion having a long side elongated in a direction perpendicular to the direction in which said nut protrudes.
