A moveable circular collet is attached to a plunged and travels from a pre-driven position wherein the collet is substantially free from engagement with the internally threaded legs and allows for flexure of the internally threaded legs and a fully driven position wherein the collet engages the internally threaded legs in a locked position, inhibiting flexure and engaging the externally threaded stud.
Description
SOCKING CLIP WITH MOVEABLE COL ~' BACKGROUND OF THE INVENTION
Field of the Invention This invention pertains to a locking clip with a base with multiple internally threaded legs and a moveable collet to encircle the legs in an. engaged position.
Description of the Prior Art ' In the prior art, it is known to design a clip, such as a pipe clip, rod end clip or a similar clip. These prior art clips .
frequently require a rotational or screwing movement to engagerthe internal threads of the clip to an externally threaded structural member such as a threaded stud or bolt-like structure. This requires a relatively lengthy installation procedure including rotational movement which can ultimately be very costly in assembly-line production, such as automotive manufacturing:
Similarly, many prior art clips comprise a plurality of individual parts. This adds to the complexity to the manufacturing, packaging, shipping and installation of the clips:
Some examples of cl.ips'in the prior art include U.S. Patent No. 5,460,342 entitled "Retainer Element, Specifically for Motor Vehicle Bodies issued , on October 24, 1995 to Dore e~ al. : U.S.
Patent No. 5, 271,587 entitled "Clip for Pipes and Cables" issued on .
December 21, 1993 to Schaty et al.; U.S. Patent No. 4,541,602 entitled "Pipe Clip" issued on September 17, 1985 to Potzas et al.:
and U.S. Patent No. 4,518,297 entitled "Molded Plastic Socket with Easy-On Hard-Off Stud Engager" issued on May 21, 1985 to Kraus.
SUMMARY OF THE INVENTION
Accordingly, this invention seeks to provide a clip, such as a pipe clip, a rod end clip or a similar clip, which can be installed with a minimum of rotational movements, particularly when engaging an externally threaded structural element such as a stud or bolt-like structure.
Further, this invention seeks to provide a clip, such as a pipe clip, a rod end clip or a similar clip, which can be easily installed and is well-adapted for assembly line installation.
Still further, this invention seeks to provide a clip, such as a pipe clip, a rod end clip or a similar clip, which can be economically manufactured, packaged, shipped and installed as a single piece.
The invention in one broad aspect provides a clip including a plurality of internally threaded legs forming a base having an aperture therein with sidewalls rising from the base to an upper surface having an opening therein. A collet which passes through the opening can move from a pre-driven position to a fully driven position. The collet is substantially free of engagement with the plurality of internally threaded legs in the pre-driven position thereby allowing flexure of the plurality of internally threaded legs and wherein the collet encircles and engages the plurality of internally threaded legs in the fully driven position, thereby inhibiting flexure of the plurality of internally threaded legs.
More particularly there is provided a clip which includes multiple internally threaded legs on a base element and a move-able collet to encircle the legs in the installed position. Pref-erably, the collet is molded integrally with the base in the manu-facturing process. The collet is then pre-driven to a position that limits the deflection of the threaded legs when the clip is installed on the stud. Matching tapers on the outside of the legs and the inside of the collet allow this limited deflection.
Tabs and protrusions hold the collet in the desired position. The threaded legs are flexible and are designed to partially surround the stud. Upon installation, the internal taper of the legs center the clip on the stud. The limited travel of the legs provides audible and tactile feedback to the installer and ensures proper mating of the threaded stud to the threaded legs. Once the clip is fully against the panel, the installer drives the collet to a fully installed position.--The matching tapers substantially contact each other thereby preventing a further deflection of the legs, locking the clip to the stud. Tabs retain the collet in a fully driven or installed position. For serviceability, the collet can be pried back up with a screwdriver freeing ' the clip for a straight p»ll -removal. The clip can also be unscrewed in a conventional way.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in detail wherein like numerals refer to like elements throughout the several views, one sees that Figure 1 is a front plan view; partially in phantom of the stud retainer embodiment 1.0 of the present invention. Generally planar base 12 is formed with aperture 14 passing through a center thereof (also. ee_-Figure 3). Alternately opposed internally threaded legs 16, 18 rise from base 12 and~ form 90' of the internal circumference of aperture 14, with 90' separating alternately opposed internally threaded legs 16, 18 from each other: The internal threads of legs 16, 18 are designed to engage an externally. threaded structure such as.a stud or other bolt-like structure (not shown) In the pre-driven positions shown in Figures 4a and 4b and additionally in the as-manufactured or as-molded positions as shown in Figures 1 and 2, there s enough flexibility within alternately opposed internally threaded legs 16, 18 that the- stud or other bolt-like structure (not shown) can be inserted between threaded legs 16; 18 and threadedly engaged ,therebetween by a relatively linear motion, without the necessity for substantial rotational or screwing motion. External opposed .sidewalls 20, 22 rise perpendicularly from base 12 and support planar top 27. First detent notch 2~ is formed immediately downwardly adjacent from planar top ~7: Second detent notch 29 is formed with cross-member 31 spans external' opposed sidewalls 20, 22, above internally- tapered wall 24 but below planar top 27.
Alternately opposed internally threaded legs l6, 18 have externally tapered walls 24, 26, respectively. Downwardly tapered partially toroidal channel 28 is formed between externally tapered walls 24, 26 of alternately opposed internally threaded legs 16, 18 and external opposed sidewalls 20, 22.
Plunger 30 includes head 32 and shaft 34. Collet -36 is fonaed at the bottom of shaft 34 and is initially molded as adjoining planar top 27. The connection between collet 36 and planar top 27 is subsequently broken in order to reach the pre-driven or fully driven position. Shaft 34 further is formed from horizontal elements 38, 40. Outwardly extending pre-drive positioning tabs .
42, 44 are formed on collet 36 and hori2ontal :element '38, respectively. Internal inclined wall 46 is formed withiWshaft 34 by the internal inclined surfaces of 48, 50, 52 of collet 36 and horizontal elements 38, 40, respectively. Internal inclined wall 46, as formed by internal inclined surfaces 48, 50, 52, has an angle of inclination complementary to that of externally. tapered walls 24, 26. Cylindrical portion 54 is formed. immediately below head 32 as part of shaft 34 and includes radially extending alignment element 56 and full drive-retention tab 58.
In the pre-driven position shown in Figures 4a and 4b, outwardly extending pre-drive positioning tabs 42, 44 engage second detent notch 29 and first detent notch 25, respectively.: After the pre-driven position is achieved and the stud (not shown) is engaged' between alternately opposed internally threaded legs 16, 18, the installer typically drives plunger 30 downwardly to the fully driven position shown in Figures 4c and 4d so that full drive retention tab 58 engages first detent notch 25 and horizontal element 40 engages second detent notch 29. Most importantly, collet 36 extends through downwardly tapered partially toroidal channel 28 and internal inclined wall 46 engages externally tapered walls 24, 26 of internally threaded legs 16, 18, thereby locking the internal threads of legs 16, 18 against the externally threaded stud or other bolt-like- element -(not shown) . - ---.-- -. - --Figures 5, 6 and 7 disclose a pipe clip embodiment 60 of the present invention. Pipe clip embodiment 60 includes all of the elements of the stud retainer embodiment 10 and further includes pipe clip retaining elements 62, 64 integrally formed with ~tnd extending from sidewalls 20, 22, respectively.
Figure 8-14 disclose a locking clip embodiment- 70 of the present invention. Docking clip embodiment 70 is similar to stud retainer embodiment l0. However, plunger 30 includes cylindrical wall 72 with collet retention tabs 74, 76 at a lower end thereof:
Collet retention tabs 74, 76 are formed integrally with planar top 27 in the as-molded or as-manufactured position shown in Figures 9 and 10. This connection between the collet retention tabs 74, 76 and .planar top 27 -is subsequently broken to reach the pre-driven -or fully driven position. Collet retention tabs 74, 7f engage edge 78 formed underneath planar top 27 in the pre-driven position shown in Figures il and 12 and abut base 12 in the fully driven position ' shown in Figures 13 and 14.
Full drive retention tab 80: is formed at a relatively upward portion of plunger 30 and pre-drive positioning tabs 82, 84 are formed at somewhat lower positions along plunger 30. As can be seen- from Figure 12, in the pre-driven position, pre-drive positioning tab 82 abuts planar top 27 while pre-drive positioning tab 84 engages detent notch 86 formed within planar top 27. As can be seen from Figure 14, in the fully driven position; full drive retention tab 80 engages detent notch 86.
Figure 15-19 disclose the rod end clip e~abodiment 90 of the present invention. Alternately opposed internally threaded legs 16, 18 are integrally molded on end 92 of cylindrical support 94 and shares a, common longitudinal axis therewith. Cylindrical support 94 likewise integral with generally cubic body 96 which,' in turn, is integral with panel clip 98: Panel clip,98 is oriented at a right angle with respect to cylindrical support 94 and legs 16,;
18. Panel clip 98 is generally cylindrical for being inserted through an aperture of a panel (not shown), and further includes radially extending wings 100, 102 so that a panel can be .engaged within gap 104 formed between wings 100, 102 and cubic body 96.
Full drive retention wings 106, 108 extend radially outwardly from legs 16, 18 respectively. Pre-drive positioning.tabs i10, 112 are .
formed~radially outward proximate to end 92 of cylindrical support .
94 . - . , Collet 36 is formed as a narrowed neck 114 of externally sliding plunger 116. Sliding plunger 116 further includes enlarged' portion 118. Narrowed neck 114 is initially molded at the ends of legs l6, 18 as shown in Figure 19. The integral connection between narrowed neck 114 and legs 16, 18 is subsequently broken to reach the pre-driven or fully driven positions. In order to: reach the pre-driven position, -narrowed neck 114 is driven past legs 16, 18 to engage cylindrical support 94 in the position shown in Figures 15 and 16 and.is held in this position by cylindrical body 96 on one end and pre-drive positioning tabs 110, 112 on the other end:
In order to reach the fully driven position or installed position shown in Figure l8.from---the-pre-driven position of Figures l5 and 16, the sliding plunger 116 is withdrawn away from cubic body 96 so that narrowed neck 114 is positioned between full drive retention wings 106, 108 and pre-drive. positioning tabs 110, 112 and engaging legs l6, 18 thereby limitiwg deflection of legs 16, 18 and locking legs 16, 18 about an externally threaded stud or other bolt-like structural element.
In order.to install any of the embodiments 10, 60, 70, 90 of the present invention.,; the installer typically begins in the respective pre-driven position-wherein legs 16, i8 have~an ability to deflect. The user then inserts an externally threaded stud or other bolt-like structure between legs l6, l8 and urges collet 36 to the fully driven position thereby limiting the deflection of legs 16, 18 and locking legs 16,. 18. to the stud: Other connections,.such as to pipes or wires with pipe clip 60 or to a panel such as with rod end .clip 90; may be done before o~ after the locking of legs 16, 18 as described above.
Thus the several aforementioned objects and advantages are most effectively attained. Although preferred embodiments of the invention have been disclosed and described in detail herein, it should be understood that this invention is in no sense 1 invited thereby and its scope is to be determined by that of the appended claims.
Field of the Invention This invention pertains to a locking clip with a base with multiple internally threaded legs and a moveable collet to encircle the legs in an. engaged position.

Cylindrical support 94 likewise integral with generally cubic body 96 which,' in turn, is integral with panel clip 98: Panel clip,98 is oriented at a right angle with respect to cylindrical support 94 and legs 16,;
18. Panel clip 98 is generally cylindrical for being inserted through an aperture of a panel (not shown), and further includes radially extending wings 100, 102 so that a panel can be .engaged within gap 104 formed between wings 100, 102 and cubic body 96.
Full drive retention wings 106, 108 extend radially outwardly from legs 16, 18 respectively. Pre-drive positioning.tabs i10, 112 are .
formed~radially outward proximate to end 92 of cylindrical support .
94 . - . , Collet 36 is formed as a narrowed neck 114 of externally sliding plunger 116. Sliding plunger 116 further includes enlarged' portion 118. Narrowed neck 114 is initially molded at the ends of legs l6, 18 as shown in Figure 19. The integral connection between narrowed neck 114 and legs 16, 18 is subsequently broken to reach the pre-driven or fully driven positions. In order to: reach the pre-driven position, -narrowed neck 114 is driven past legs 16, 18 to engage cylindrical support 94 in the position shown in Figures 15 and 16 and.is held in this position by cylindrical body 96 on one end and pre-drive positioning tabs 110, 112 on the other end:
In order to reach the fully driven position or installed position shown in Figure l8.from---the-pre-driven position of Figures l5 and 16, the sliding plunger 116 is withdrawn away from cubic body 96 so that narrowed neck 114 is positioned between full drive retention wings 106, 108 and pre-drive. positioning tabs 110, 112 and engaging legs l6, 18 thereby limitiwg deflection of legs 16, 18 and locking legs 16, 18 about an externally threaded stud or other bolt-like structural element.
In order.to install any of the embodiments 10, 60, 70, 90 of the present invention.,; the installer typically begins in the respective pre-driven position-wherein legs 16, i8 have~an ability to deflect. The user then inserts an externally threaded stud or other bolt-like structure between legs l6, l8 and urges collet 36 to the fully driven position thereby limiting the deflection of legs 16, 18 and locking legs 16,. 18. to the stud: Other connections,.such as to pipes or wires with pipe clip 60 or to a panel such as with rod end .clip 90; may be done before o~ after the locking of legs 16, 18 as described above.
Thus the several aforementioned objects and advantages are most effectively attained. Although preferred embodiments of the invention have been disclosed and described in detail herein, it should be understood that this invention is in no sense 1 invited thereby and its scope is to be determined by that of the appended claims.
