Abstract
The patent discloses a crimp sleeve for the fixation of two or more sections of wire, line, or similar material to each other. The crimp sleeve consists of an outer compressible and permanently deformable layer which is hard and resistant, and an inner cushion layer, which is softer and which conforms to the sections of material to be attached to each other. The multi-layered structure of the crimp sleeve allows for secure fixation without the risk of breakage or slippage of the connection. The invention applies primarily to fishing leaders that have looped ends, but can be applied to other areas where two or more sections of wire or line need to be secured to each other by crimping.

DETAILED DESCRIPTION OF THE INVENTION
[0060] FIG. 1A shows a standard fishing leader loop end 10, the loop being secured by compressed conventional crimp single-barrel sleeve 16, compressed. Shown is bite-mark 12, the indentation of crimp sleeve 16 caused by the crimping plyers during the compression process.
[0061] FIG. 1B shows an orthogonal cross sectional view of the crimped area. As can be seen, compressed leader material 20 has been deformed out of its originally round shape. Further, there are multiple spaces 18 of un-apposed support wall 22 of the crimp sleeve, indicating that in that space compressed leader material 20 is not secured against slippage.
[0062] FIG. 1C shows once again the crimped area. Support wall 22 of the crimp sleeve is indented owing to the crimping tool, however, the pressure exerted on compressed leader 20 is uneven, leading not only to areas 18 of un-opposed support wall 22 (shown in FIG. 1B), but also areas of injury 24 to compressed leader 20. Such areas of injury 24 create focal weakness and a potential starting point for leader rupture.
[0063] FIG. 1D shows a standard fishing leader loop end 10, the loop being compressed with a conventional double-barrel crimp sleeve 26. Bite mark 12 is again depicted.
[0064] FIG. 1E shows that, similar to a single-barrel type standard crimp sleeve, the double-barrel model leads to deformation of the compressed leader material 20, and there are spaces of un-apposed support wall 22, setting the loop up for failure due to slippage.
[0065] FIG. 1F shows a longitudinal cross sectional view of the crimped area, using a conventional double-barrel type crimp sleeve 26. Similar to a conventional single-barrel crimp sleeve, there are both areas 18 of un-apposed support wall 22 and areas of injury 24 to compressed leader material 20, potentially causing slippage or breakage, respectively.
[0066] FIG. 2A shows a perspective view of an uncompressed first embodiment 30 of a novel type crimp sleeve. The crimp sleeve has an outer layer 32 of hard, compressible material (e.g. steel, aluminum, copper), and an inner cushioning layer 34, made out of material such as comparatively soft metal (e.g. tin, lead), or plastic, or another deformable solid material.
[0067] FIG. 2B shows layers 32 and 34 of the uncompressed first embodiment 30 in a longitudinal cross sectional view.
[0068] FIG. 2C shows a perspective view of an uncompressed second embodiment 40 of the novel type crimp sleeve. This crimp sleeve embodiment 40 is divided, for purposed of illustration, into proximal end 72, distal end 74, and mid-section 76. Crimp sleeve embodiment 40 features an outer layer 42 of hard, compressible material. However, this outer layer 42 does not extend along the entire length of crimp sleeve 42. Inner cushioning layer 44 does extend along the entire length of sleeve embodiment 40, broadening at the proximal 72 and distal 74 ends, thereby surrounding and enveloping outer layer 42 on three sides.
[0069] FIG. 2D shows the relationship of support layer 42 and cushioning layer 44 of uncompressed second embodiment 40, using a longitudinal cross sectional view.
[0070] FIG. 2E shows a perspective view of a first embodiment 50 of an uncompressed novel type double-barrel crimp sleeve. Similar to the novel single-barrel crimp sleeve 30, novel double-barrel crimp sleeve 50 has an outer layer 52 of hard, compressible material, and an inner cushioning layer 54. Also shown is hatched reference line 80, which refers to the subsequent illustration.
[0071] FIG. 2F shows layers 52 and 54 in a longitudinal cross sectional view in this uncompressed double-barrel model 50. Note that the cross sectional view is obtained at a point corresponding to hatched reference line 80 of FIG. 2E.
[0072] FIG. 2G shows a perspective view of a second embodiment 60 of the novel type crimp sleeve, as applied to an uncompressed double-barrel model. Again, for purposed of illustration, it is divided into proximal end 72, distal end 74, and mid-section 76. Crimp sleeve embodiment 60 has an outer layer 62 of hard, compressible and permanently deformable material, extending only along mid-section 76. Cushioning layer 64 does extend the entire length of sleeve embodiment 60, broadening at the proximal 72 and distal 74 ends, thereby surrounding and enveloping outer layer 62 on three sides. Also shown is hatched reference line 90, which refers to the subsequent illustration.
[0073] FIG. 2H shows the relationship of support layer 62 and cushioning layer 64 of second embodiment 60, uncompressed double barrel type, using a longitudinal cross sectional view. Note that the cross sectional view is obtained at a point corresponding to hatched reference line 90 of FIG. 2G.
[0074] FIG. 3A shows the first embodiment of the new crimp sleeve, compressed and as applied to a single-barrel crimp model. Support wall 32, following the crimping process, shows rugged deformations and jagged edges both on the outside 92 and on the inside 94. Such jagged edges on the inside 94 are liable to introduce areas of injury to compressed leader material 20 in conventional crimp sleeves. Owing to cushioning layer 34, however, such injury cannot be imparted on leader material 20 in this new crimp sleeve 30.
[0075] FIG. 3B shows the special relation of support wall 32, cushioning layer 34, and compressed leader material 20 in this first embodiment of the novel crimp sleeve 30, as applied to a single barrel crimp sleeve model. Compressed leader material 20 undergoes some deformation (as evidenced by the fact that its usual round cross-sectional shape is lost), however, there are no areas of injury 24 to leader material 20, since compressed material 20 is spatially separated from the hard material of support wall 32. Further, as also seen in this orthogonal cross-sectional view, cushioning layer 34 completely surrounds both strands of compressed leader material 20, without un-apposed areas 18. It is plainly evident that this significantly reduces the chance of breakage of the leader loop due to weakening of compressed leader material 20 or slippage of the same.
[0076] FIG. 3C shows the second embodiment of the new crimp sleeve, as applied to a single-barrel crimp model. Support wall 42 extends only along mid-section 76. Cushioning layer 44 broadens at proximal end 72 and at distal end 74, surrounding support wall 42 on three sides. This modification, avoiding any hard crimping material at the proximal or distal edges of the crimp, further reduces the chance of injury to the compressed leader material 20 due to uneven crimping.
[0077] The foregoing embodiments are presented by way of example only; the scope of the present invention is to be limited only by the following claims.
