Abstract
Abstract A device for threading strings or the like through bores of an anchoring part consisting of a tube detachably secured to a handle with a stylus extending from the handle and being received within the tube. The free tip of the stylus projects beyond the forward end of the tube. The device is inserted within the bore, the handle and stylus are subsequently withdrawn, and the tube remains in the bore. A thread is then inserted in the tube. This is followed by removal of the tube leaving the string threaded within the bore.

Claim 1
Independent Claim
93 words
Device for threading strings or the like in a through bore of an anchoring part, frame, or the like, characterized by a handle (10, 80, 82), a tube (14) connected to the handle, the inside diameter of said tube matching the outside diameter of the string (50) to be threaded with play, and by a stylet (12, 56) with a tapered rounded tip (29,58), said stylet being insertable in the tube (14) in such manner that it partially fills the tube and partially projects beyond the forward end (34, 64) of the tube.
Claim 2
Dependent Claim
93 words
Device for threading strings or the like in a through bore of an anchoring part, frame, or the like, characterized by a handle (10, 80, 82), a tube (14) connected to the handle, the inside diameter of said tube matching the outside diameter of the string (50) to be threaded with play, and by a stylet (12, 56) with a tapered rounded tip (29,58), said stylet being insertable in the tube (14) in such manner that it partially fills the tube and partially projects beyond the forward end (34, 64) of the tube.
Claim 3
Dependent Claim
38 words
Device according to claim 1, characterized by the fact that tube (14) is firmly connected to handle (80) and by the fact that stylet (56) is insertable into the tube from the free end (64) of said tube.

Dependent Claim
62 words
Device according to claim 1, characterized by the fact that tube (14) is mounted in a through axial bore (30) of an inserting part (16, 90) and projects from the forward end of said part, and by the fact that the inserting part (16, 90) is extractable with handle (10, 82), but is nonrotatably connected thereto with respect to the withdrawal direction.
Claim 5
Dependent Claim
42 words
Device according to claim 3, characterized by the fact that stylet (12) is firmly connected to handle (10, 82) and passes through the entire axial bore (30) of the inserting part when said inserting part (16, 90) is in the nonretracted state.
Claim 6
Dependent Claim
19 words
