Abstract
A clip includes a clip body having a flange formed with an insertion hole for receiving a pin; and a substantially cylindrical leg which projects from the bottom surface of the flange, has a hollow interior communicating with the pin insertion hole, and is divided by a plurality of slits formed in the axial direction of the wall thereof into a plurality of segments each formed on the inner side of the tip thereof with a catch projection. The pin has a head and a shaft projecting from the bottom surface of the head, and is formed with a catch for engaging with the catch projections. Each split of the clip body leg is formed wide at the end near the flange and narrow near the tip and the surface of the pin is provided with a plurality of ribs extending in the axial direction of the leg for insertion into at least the wide portions of the slits of the leg.
Claims24
A clip, comprising:
- a clip body having a longitudinal axis;
- and
- a pin, having a longitudinal axis substantially coaxial with said longitudinal axis of said clip body, for insertion into said clip body;
- said clip body having a flange formed with an insertion hole for receiving said pin;
- and a substantially cylindrical leg, disposed about said longitudinal axis of said clip body, projecting from a bottom surface portion of said flange, wherein said leg has a hollow interior communicating with said pin insertion hole defined within said flange and is divided, by means of a plurality of axially extending slits formed within peripheral wall portions thereof, into a plurality of segments wherein each segment is formed on the inner side of a tip portion thereof, remote from said flange, with a catch projection, and wherein each one of said plurality of slits is formed relatively wide at the end disposed near said flange and relatively narrow at the end disposed near said tip portion;
- and
- said pin has a head, and a shaft projecting from a bottom surface portion of said head and adapted for insertion into said hollow interior of said leg of said clip body;
- said shaft being formed with a catch for engaging said catch projections of said leg segments of said clip body and thereby expanding said leg segments of said clip body radially outwardly, and a plurality of axially extending ribs having wide portions extending from said bottom surface portion of said head of said pin toward said catch of said pin, said ribs having width dimensions substantially similar to the width dimensions of said relatively wide portions of said slits of said leg of said clip body for insertion into said relatively wide portions of said slits of said leg of said clip body so as to provide said clip with increased resistance to shearing forces.
In combination, a clip for securing two plates together, comprising:
- a first plate having a first hole defined therethrough;
- a second plate having a second hole defined therethrough;
- a clip body having a longitudinal axis, a flange for engaging one surface of said first plate and formed with an axially extending through-hole, and a substantially cylindrical leg portion, disposed about said longitudinal axis of said clip body, projecting from a bottom surface portion of said flange, wherein said leg portion has a hollow through-bore in communication with said through-hole of said flange and is divided, by means of a plurality of axially extending slits formed within peripheral wall portions thereof, into a plurality of segments wherein each segment is formed, upon a radially inner side of a tip portion thereof remote from said flange, with a catch projection, and wherein each one of said plurality of slits is formed relatively wide at the end disposed adjacent to said flange and relatively narrow at the end disposed adjacent to said tip portion;
- and
- a pin having a longitudinal axis substantially coaxial with said longitudinal axis of said clip body, a head, and a shaft projecting from a bottom surface portion of said head for insertion through said through-hole of said flange of said clip body and into said through-bore of said leg portion of said clip body;
- said shaft being formed with a catch for engaging said catch projections of said leg segments of said clip body and thereby expanding said leg segments of said clip body radially outwardly into engagement with said second plate whereby said first and second plates are secured together between said flange of said clip body and said expanded leg segments of said clip body, and a plurality of axially extending ribs having wide portions extending from said bottom surface portion of said head of said pin toward said catch of said pin, said ribs having width dimensions substantially similar to the width dimensions of said relatively wide portions of said slits of said leg portion of said clip body for insertion into said relatively wide portions of said slits of said leg portion of said clip body so as to provide said clip with increased resistance to shearing forces.
