Device for tying an elongate object, for example a cable trunk

Claim 3

The device of claim 1 wherein said second catch edge extends annularly about said pin.

Claim 4

The device of claim 1 wherein said lock body has a side adapted to be disposed toward the object to be tied and said side is reinforced by fins oriented laterally of the passage orifice.

Claim 5

The device of claim 3 wherein one band end is connected integrally to said lock body with said fins merging into said band.

Claim 6

The device of claim 1 wherein said band passageway has a longitudinal axis extending inwardly from said entrance opening and said lock body has an outer surface adapted to be disposed adjacent the surface of the object to the tied, said outer surface having a band directing portion forming an angle of more than 90° with the longitudinal axis of the band passageway.

Claim 7

In combination, an elongated object to be tied, and a tying device comprising a band having opposite ends and wrapped around said object so as to be under tension, and a lock assembly connecting the band ends comprising a lock body positioned adjacent said object having a band-receiving passageway, a borehole with upper and lower portions extending transversely through said passageway so that said upper portion is above said passageway and said lower portion is below said passageway, and a first step surface adjacent said lower portion of said borehole and disposed toward said object, said first step surface facing upwardly toward said upper portion of said borehole, one of said band ends extending through said passageway, and a driving pin having upper and lower ends mounted within the upper and lower portions respectively of said borehole with said upper end engaging said one band end to form a deep-drawn pot-shaped configuration of said one band end about said upper end of said pin, with the tension of said one band end exerting a force on said pin downwardly and toward said object, said pin having a second step surface disposed toward said object and facing downwardly, said second step surface directly engaging said first step surface of said lock body to retain said pin in said borehole, said force on said pin from said one band end urging said pin toward said object so as to tend to increase the amount of mutual engagement between said first and second step surfaces and to press said second step surface directly against said first step surface.

Claim 8

In combination, an elongated object to be tied, and a tying device comprising a band having opposite ends and wrapped around said object so as to be under tension, and a lock assembly connecting the band ends comprising a lock body positioned adjacent said object having a band-receiving passageway, a borehole with upper and lower portions extending transversely through said passageway so that said upper portion is above said passageway and said lower portion is below said passageway, and a first step surface adjacent said lower portion of said borehole and disposed toward said object, said first step surface facing upwardly toward said upper portion of said borehole, one of said band ends extending through said passageway, and a driving pin having upper and lower ends mounted within the upper and lower portions respectively of said borehole with said upper end engaging said one band end to form a deep-drawn pot-shaped configuration of said one band end about said upper end of said pin, with the tension of said one band end exerting a force on said pin downwardly and toward said object, said pin having a second step surface disposed toward said object and facing downwardly, said second step surface directly engaging said first step surface of said lock body to retain said pin in said borehole, said force on said pin from said one band end urging said pin toward said object so as to tend to increase the amount of mutual engagement between said first and second step surfaces and to press said second step surface directly against said first step surface.

Claim 9

The combination of claim 6 wherein said upper end of said pin has an offset portion offset toward said object so as to form said second step surface, said second step surface facing downwardly toward said lower end.

Claim 10

The combination of claim 6 wherein said pin is generally cylindrical with an outer surface and an annular projection extending outwardly from said outer surface, said annular projection having a lower surface forming said second step surface.

Claim 11

The combination of claim 8 wherein said said second step surface is perpendicular to said outer surface of said pin.

Claim 12

The combination of claim 6 wherein said object is a cable bundle.

Claim 13

The combination of claim 6 wherein said lock body has first and second sides with said first side being disposed toward said object and said band-receiving passagway extending from said first side outwardly away from said object to said second side, said first side having reinforcing fins dispersed laterally from said passageway.

Claim 14

The combination of claim 11 wherein the other of said band ends is integrally connected to the lock body and said fins comprise elongated fins integrally merging longitudinally into said band.

Claim 15

The combination of claim 6 wherein the other of said band ends is integrally connected to said lock body.

Claim 16

The combination of claim 6 wherein said lock body has a side surface disposed toward said object and having an abutment portion abutting said band so that said band extends into said passageway at an angle less than 90°.
