Technical Field

The present invention relates generally to hose clamps, and more particularly, to a locator system and method for a hose clamp.

Background

Typically, the hose is clamped to the tube to secure the hose to the tube. During assembly, the clamp may be positioned over the end of the hose prior to coupling the hose to the fitting. The clamp and hose end can then be positioned over the tube, and the clamp can be tightened (e.g., run-down) to secure the hose to the tube. This assembly can be time consuming as it requires an additional step of positioning the clamp on the hose end. To speed up assembly, some hoses are provided to the end user with a clamp pre-fitted on the hose end. Thus, it is desirable to position and hold the clamp on the hose end (e.g., during transport of the hose/clamp assembly to the end user).

Detailed Description

While the concepts of the present invention are susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit the concepts of the present disclosure to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives consistent with the present disclosure and the appended claims.

References in the specification to "one embodiment," "an illustrative embodiment," etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may or may not include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that: it is within the knowledge of one skilled in the art to effect such a feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

In the drawings, some structural or method features may be shown in a particular arrangement and/or ordering. It should be understood, however, that such specific arrangement and/or ordering may not be required. Rather, in some embodiments, such features may be arranged in a manner and/or order different from that shown in the illustrative figures. Additionally, the inclusion of a structural or methodical feature in a particular figure is not intended to imply that such feature is required in all embodiments, and in some embodiments, this feature may not be included or may be combined with other features.

Referring to fig. 1-3, the locator tab 10 includes a body 12 and a gripping end 14 extending from the body 12. The body 12 includes a top rail 20, legs 22 extending from an end 24 of the rail 20, and legs 26 extending from an opposite end 28 of the rail 20. A foot 40 extends from an end 42 of the leg 22. The clamping end 14 extends from the end 44 of the leg 26.

The crossbar 20 includes an angled section 50 coupled to an angled section 52 by a rounded section 54. The rounded section 54 is located at the center of the crossbar 20 and thus acts as a central beam for the crossbar 20. The angled section 52 extends from the end 24 to a rounded section 54. Angled section 54 extends from end 28 to rounded section 54. The angled, and rounded sections 50, 52, 54 collectively form a crossbar 20 that is not parallel to the hose clamp's strap at least when the strap of the hose clamp (see, e.g., fig. 8, 16, and 18) is held by the locator tab 10. As can be seen in fig. 3, by way of example, the crossbar 20, angled section 50, and angled section 52 collectively form the M-shape of the body 12 of the locator tab 10.

The pawl 60 extends downwardly from a bottom surface 62 of the rounded section 54. The detent 60 is configured to be received in a recess (e.g., groove, ridge, hole, opening, etc.) formed in the band of the hose clamp when the band of the hose clamp is retained by the locator tab 10. As such, the detent 60 retains the locator tab 10 in a predetermined circumferential position on the hose clamp (prior to tightening the band of the hose clamp).

In some embodiments illustrated in fig. 38-41, the detents 60 may be formed as strain tabs 64 that pass through the crossbar 20. The tabs 64 provide a relief window 66 through the crossbar 20 through which the hose clamp can be seen. The tab 64 can be received in a recess formed in the band of the hose clamp to retain the locator tab 10 in a predetermined circumferential position on the hose clamp (prior to tightening the band of the hose clamp). When the band of the hose clamp is tightened onto the hose, the recess formed in the band of the hose clamp disengages from the pawl 60 (or tab 64).

The body 12 of the locator tab 10 includes an opening 70. An opening 70 extends through the leg 22 and a portion of the angled member 50. The opening 70 is positioned at the end 24 of the crossbar 20. A flange 72 extends through the opening 70. The flange 72 includes a crossbar section 74 extending along the angled member 50 and a leg section 76 extending along the leg 22. The body 12 includes another opening 80. An opening 80 extends through the leg 26 and a portion of the angled member 52. The opening 80 is positioned at the end 28 of the crossbar 20. A flange 82 extends through the opening 80. The flange 82 includes a crossbar section 84 extending along the angled member 52 and a leg section 86 extending along the leg 26.

By way of example, fig. 1-3 illustrate the flanges 72, 82 in an open configuration. In the open configuration, the locator tab 10 can be positioned on a hose clamp. The hose clamp is configured to be positioned below the crossbar 20 and between the legs 22 and 26. When the band of the hose clamp is positioned between the legs 22 and 26, the flanges 72, 82 flex inwardly to a closed configuration, as illustrated in fig. 4-6 (by way of example). In this configuration, the band of the hose clamp is held between the crossbar 20 and the flanges 72, 82. When the band of the hose clamp is tightened, pressure from the hose clamp flexes the flanges 72, 82 back to the open configuration so that the hose clamp can be tightened around the hose (e.g., to secure the hose to the pipe).

Referring back to fig. 1-3, the gripping end 14 includes an expanded mouth 100 having a first segment 102 extending from the end 44 of the leg 26. A second segment 104 of the expanded port 100 extends from the first segment 102, and a third segment 106 of the expanded port 100 extends from the second segment 104. The curved shape of the expansion 100 (see, in particular, fig. 3) provides clearance to allow the band and/or liner of the hose clamp to travel relative to the locator tab 10.

A hose retainer 120 extends from the flared port 100. The hose retainer 120 includes an upper end 122 and a side 124 extending from the upper end 122. A pair of teeth 126 extend from the side 124. Collectively, upper end 122, sides 124, and teeth 126 define a cavity 128 configured to receive a hose end. The teeth 126 include points 130 configured to bite into the inner hose wall of the hose end. That is, the teeth 126 are bent inward toward the inner hose wall to tighten the point 130 into the inner hose wall and secure the locator tab 10 to the hose. Those skilled in the art will appreciate that this design allows the hose retainer 120 to be secured to hoses of various sizes and wall thicknesses.

Thus, the locator tab 10 is secured to both the hose clamp and the hose to locate the hose clamp on the hose for assembly. In this configuration, the hose can be shipped to the end user with the hose clamp secured to the hose. This enables the end user to save time by positioning the hose and hose clamp on the tube simultaneously. Fig. 7 illustrates three locator tabs 10 positioned at different circumferential locations on the hose clamp 140. Fig. 8 illustrates a hose clamp 140 positioned between the crossbar 20 and the flanges 72, 82. Fig. 15 and 16 illustrate three locator tabs 10 positioned on the hose 170 in an undamped position. Fig. 17 and 18 illustrate three locator tabs 10 positioned on a hose 170 in a clamped position. In some embodiments, such as the embodiment shown in fig. 19 and 20, only two locator tabs 10 are utilized to locate the hose clamp 140 on the hose 170.

When coupling the hose 170 to the end of the tube, the clamp 140 is tightened onto the hose 170 and the tube to secure the hose to the tube. Fig. 21-23 illustrate a clamp 140 secured to a hose 170 using three locator tabs 10. Fig. 24 and 25 illustrate a clamp 140 secured to a hose 170 utilizing two locator tabs 10.

Fig. 9 and 10 illustrate another embodiment of a locator tab 200. The locator tab 200 includes a body 202 and a gripping end 204 extending from the body 202. The body 202 includes a top crossbar 220, legs 222 extending from the crossbar 220 at ends 224, and legs 226 extending from opposite ends 228 of the crossbar 220. A foot 240 extends from an end 242 of the leg 222. As illustrated in fig. 9 and 10, the feet 240 may extend inward. Optionally, the foot 240 may extend outward. The clip end 204 extends from an end 244 of the leg 226.

The body 202 includes an opening 270. An opening 270 extends through a portion of the leg 222 and the crossbar 220. The opening 270 is positioned at the end 224 of the crossbar 220. The flange 272 extends through the opening 270. The flange 272 is flexible and includes a curved section 274. The body 202 includes another opening 280. An opening 280 extends through a portion of the leg 226 and the crossbar 220. The opening 280 is positioned at the end 228 of the crossbar 220. The flange 282 extends through the opening 280. The flange 282 is flexible and includes a curved section 284. The flanges 272 and 282 are configured to flex outwardly in order to receive a hose clamp. Once the hose clamp is positioned adjacent the crossbar 220, the flanges 272, 282 snap back into the position shown in fig. 9 and 10, and the hose clamp is held between the crossbar 220 and the flanges 272, 282.

The clamping end 204 includes a hose retainer 320. Hose retainer 320 includes an upper end 322 and a side 324 extending from upper end 322. A pair of teeth 326 extend from the side 324. Collectively, upper end 322, sides 324, and teeth 326 define a cavity 328 configured to receive a hose end. The teeth 326 include points 330 configured to bite into the inner hose wall of the hose end. That is, the tines 326 are bent inward toward the inner hose wall to tighten the points 330 into the inner hose wall and secure the locator tabs 200 to the hose. Those skilled in the art will appreciate that this design allows hose retainer 320 to be secured to hoses of various sizes and wall thicknesses.

Thus, the locator tab 200 is secured to both the hose clamp and the hose to locate the hose clamp on the hose for assembly. In this configuration, the hose can be shipped to the end user with the hose clamp secured to the hose. This enables the end user to save time by positioning the hose and hose clamp on the tube simultaneously. Fig. 11 and 12 illustrate the hose clamp 140 positioned between the crossbar 220 and the flanges 272, 282. Fig. 13 and 14 illustrate an alternative embodiment of the locator tab 200, wherein the leg 222 includes a projection 246. Additionally, as shown in fig. 13 and 14, the leg 226 may include a protruding portion 248.

Fig. 25-29 illustrate an embodiment of a locator tab 400 having a leg 402 with a protruding feature 404. Fig. 26 and 27 illustrate the flanges 406 and 408 of the locator tab 400 in an open configuration that enables the locator tab 400 to be positioned on the hose clamp 140. Fig. 28 and 29 illustrate flanges 406 and 408 in a closed configuration securing the locator tab 400 to the hose clamp 140. Figures 30 and 31 show the hose clamp 140 secured to the hose 170 with the locator tab 400.

Fig. 32-37 illustrate another embodiment of a locator tab 450 without a protruding feature in the leg 452. Fig. 32 and 33 illustrate the locator tab 450 having flanges 454 and 456 in an open configuration to enable the locator tab 450 to be coupled to the hose clamp 140. Fig. 35-37 illustrate locator tabs 450 used to couple the hose clamp 140 to the hose 170.

As shown in fig. 36 (and fig. 18, 22, 23, 25, 30, 31, 37, and 45), the teeth 126, 326, 552 of the locator tab can be configured such that, when engaged with the inner surface of the hose 170, the inner surface of each tooth is flush with the inner surface of the hose. It is also contemplated that, in some embodiments, the engagement of the teeth 126, 326, 552 of the locator tabs with the inner surface of the hose may compress the hose to some extent. For example, in some embodiments, the engagement of the teeth 126, 326, 552 of the locator tabs with the inner surface of the hose can compress the hose such that the outer surface of each tooth is flush with (or even recessed below) the inner surface of the uncompressed portion of the hose. Such a configuration may reduce interference between the locator tabs and the tube when the hose is installed on the tube.

Referring now to fig. 42-44, the locator tab 500 includes a body 502 having a crossbar 504. Crossbar 504 includes a central beam 506 that is rounded about a radius. The central beam 506 includes a detent 508 configured to be positioned in a recess formed in a strap of the hose clamp, as described in more detail below. The pawl 508 is positioned at the center 510 of the central beam 506, extending downward from the central beam 506. In some embodiments, the pawl 508 may extend any length of the central beam 506.

The crossbar segments 520 extend from the central beam 506 at a non-orthogonal angle relative to the central beam 506. Another crossbar segment 522 extends from the central beam 506 at a non-orthogonal angle relative to the central beam 506. The rail segment 522 extends from the central beam 506 in a direction opposite the rail segment 520. In the illustrated embodiment, the crossbar segment 520 and the crossbar segment 522 extend at substantially the same non-orthogonal angle. In some embodiments, the crossbar segments 520 and 522 may extend at different angles.

The legs 530 of the body 502 extend from the crossbar segment 520. The crossbar segment 520 is at a first angle relative to the legs 530. Legs 530 extend downwardly from crossbar 504. An arm 532 extends outwardly from the leg 530, configured to be positioned on an outer surface of the hose, as described in more detail below. A flange 534 is formed in the leg 530. The flange 534 is initially planar with the leg 530. When the locator tab 500 is secured to the hose, the flange 534 is bent inward so that the hose is positioned between the flange 534 and the crossbar 504.

The legs 540 of the body 502 extend from the crossbar segments 522. The crossbar segment 522 is at a second angle relative to the leg 540. In the illustrative embodiment, the first angle between the crossbar segment 520 and the leg 530 is the same as the second angle between the crossbar segment 522 and the leg 540. In some embodiments, a first angle between crossbar segment 520 and leg 530 is different than a second angle between crossbar segment 522 and leg 540. A flange 544 is formed in the leg 540. Flange 544 is initially planar with leg 540. When the locator tab 500 is secured to the hose, the flange 544 flexes inward so that the hose is positioned between the flange 544 and the crossbar 504.

Arms 546 extend outwardly from the legs 540. The clip end 550 extends from the arm 546. The clamp end 550 includes a pair of teeth 552 configured to flex inwardly for securing to the inner surface of a hose, as described in more detail below. In some embodiments, the gripping end 550 may include any number of teeth 552.

Fig. 45 illustrates a locator tab 500 for positioning the hose clamp 570 relative to the hose 580. As illustrated in fig. 45, a hose clamp 570 is secured between the crossbar 504 and the flanges 534, 544 such that the crossbar 504 is in a non-parallel position with respect to the hose clamp 570. That is, the crossbar segment 520 and the crossbar segment 522 are angled such that the crossbar 504 is not parallel to the hose clamp 570. The detent 508 is located with a recess 572 formed in the strap of the hose clamp 570.

The locator tab 500 is also secured to the hose 580. Each arm 532 and 546 is secured against the outer surface 582 of the hose 580. The gripping end 550 of the locator tab 500 is bent inward so that the teeth 552 engage the inner surface 584 of the hose 580. In this configuration, the locator tabs 500 secure the hose clamp 570 to the hose 580 in an unstrained position. When hose clamp 570 is tightened to hose 580, flanges 534, 544 flex outwardly such that hose clamp 570 is pulled inwardly against outer surface 582 of the hose and secured to the hose. In some embodiments, the locator tabs 500 are removed once the hose clamp 570 is tightened around the hose 580. In other embodiments, the locator tabs 500 remain on the hose clamp 570 once the hose clamp 570 is tightened around the hose 580.

The locator tab 600 shown in fig. 46-49 includes all of the features of the locator tab 500; however, the arms 532 are angled inwardly. In this embodiment, the arm 532 is still configured to abut the outer surface of the hose. The locator tab 600 of fig. 46-49 also differs from the locator tab 500 in that each of the legs 530, 540 includes an expansion port 602, 604 at its end opposite the crossbar 504. Each of the expansion ports 602, 604 is angled outwardly to provide increased spacing between the legs 530, 540 at the ends of the legs opposite the crossbar 504. This increased spacing provides clearance to allow the belt and/or liner of the hose clamp to travel relative to the locator tab 600 (similar to the expanded port 100 of the locator tab 10 discussed above).

The embodiments described above provide systems and methods for pre-positioning hose clamps, such as those used in the automotive industry, in the correct orientation and position for installation. Embodiments provide a positioning system that will not interfere with the installation method or reduce the effectiveness of the clamp in sealing for coolant and air management applications. Previous designs have utilized a combination of two or three different retaining clips, some of which are permanently attached or welded to the clip assembly, which may interfere with the sealing efficiency of the clip when installed. Embodiments described herein include locator tabs that are crimped to a hose clamp and hose in as few as two locations and that will fully release the hose clamp during the installation process.

Several metrics have been used to evaluate the effectiveness of the embodiments described herein. The first metric used is a "flex test" that evaluates the radial orientation and lateral stability of the clamp, which reflects the effort that must be used by the production line operator to position and maintain engagement with the screw head of the hose clamp during the torque down process used during installation. OEM specifications for lateral stability evaluation criteria currently use the maximum deflection of a screw when the screw is subjected to a predetermined force along a normal axis formed between the hose and the interface. Earlier tests showed that the embodiments described above are consistent with the specification. Notably, the test results also indicate "when shipped"Decreasing below nominal will help minimize the deflection value.

The second metric used is a measure of the amount of radial load transmitted from the screw torque input into the hose inner diameter and measured at the seal indication. While no OEM specifications exist, this measurement method is typically released to the OEM as a means of evaluating seal efficiency. For the embodiments described herein, there is an increase in radial load and/or a decrease in variation as compared to other previous attachment methods. This performance improvement is due to the elimination of sliding friction and the elimination of welded tab features that can limit hose conformance.

The third metric used is to evaluate the "push" (ergonomic) force required to insert the assembly over the interface. Data from this test shows that the embodiments described above produce readings well below the accepted specification limits. In contrast, previous designs may easily exceed this limit due to hose twisting due to different locating tab features permanently fixed to the clamp assembly. In summary, the embodiments described herein provide a robust, but "temporary" fixation that will guide, but not limit, the tightening procedure.
