[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 591,911, filed on October 20, 2023, the disclosure of which is incorporated herein by reference. Background Art

[0002] The fixture is used to attach one or more components (e.g., an elongated article, a bundle of elongated articles) to a workpiece (e.g., a support beam, a housing). The mounting section is configured to attach the component to the workpiece by: a mounting hole defined in the workpiece (e.g., a slot, a channel, a bore); an elongated fastener (e.g., a stud, a bolt) extending from the workpiece; clamping onto an edge of the workpiece; and other means.

[0003] The fixture may include an object support configured to be attached to the component. Examples of object supports include, but are not limited to, grippers, clamps, mounts, etc. For example, the fixture may include a bracket-mounted object support including a bracket portion configured to receive, secure, and / or support one or more components. The object support may include one or more cable ties for bundling the components and / or retaining a bundle of one or more components to the object support.

[0004] Fixtures are often used in mechanical installations to position components in fixed positions relative to other components and / or equipment. For example, a user (e.g., installer, operator) can use a fixture to attach a component to a machine frame at a desired position.

[0005] A modular rail mounting system (e.g., an aluminum T-slot frame system) is one example of a workpiece. The modular rail mounting system includes a support beam (e.g., an aluminum extrusion, a plastic extrusion, an extruded channel rail) having a pair of spaced-apart side rails defining a channel (e.g., an open-top channel) therebetween. The channel can be a longitudinally extending T-shaped slot (e.g., a "T-slot") defined in the support beam. In other aspects, the channel can be a hole (e.g., an oblong hole, a slot-shaped hole), etc., defined in the workpiece.

[0006] A fixture for a modular rail mounting system includes a mounting section configured to mount the fixture to a workpiece. The mounting section may include a connector (e.g., a fastener, a fastening device). The connector may be a twist-lock connector utilizing a "twist-lock" mechanism. The twist-lock mechanism is a releasable connector that is configured to be positioned within a T-slot and locked by rotating therein. For example, the twist-lock connector may be positioned within a T-slot, and once positioned at a desired position along the length of the T-slot, the twist-lock connector may be rotated relative to the T-slot (e.g., a quarter turn, i.e., ninety degrees (90°)), causing the twist-lock mechanism to engage a support beam and lock the connector into place within the T-slot. In one example, the twist-lock connector has a slight taper, which enables a spring-lock engagement between the twist-lock connector and the side rail, and the side rail locks the fixture into place on the T-slot.

[0007] Existing modular track mounting systems with twist-lock connectors may be susceptible to shaking due to vibration and / or migration from an initial placement along the T-slot to another position. To address such shaking and / or migration issues, users may need to replace worn twist-lock connectors, add shims, and / or periodically check the installation position of the twist-lock connector on the modular track mounting system and reposition it as needed. Ultimately, taking such remedial measures may take time and labor. Summary of the invention

[0030] Twist-lock fixtures are described herein. In various aspects, the twist-lock fixture is configured to attach a component to a workpiece having a locking channel. The twist-lock fixture includes a connector configured to be received in a locking channel (e.g., a T-slot channel). The twist-lock fixture also includes a body section configured to contact a first side of the workpiece to limit longitudinal insertion of the connector into the locking channel. The body section defines a recess configured to receive a portion of a locking tab of the connector. The locking tab includes a free end configured to extend (e.g., deflect) into the recess of the body section during installation of the twist-lock fixture on the workpiece. After completing installation of the twist-lock fixture on the workpiece, the locking tab returns to a normal configuration and limits rotation of the twist-lock fixture in the locking channel in a second direction opposite to the first direction (e.g., a first rotational direction). In various aspects, further rotation in the first direction is also limited.

[0031] In this way, the twist-lock fixture can have a lower twist-in force than the twist-out force, which makes the product less likely to be inadvertently removed by others after initial installation. By limiting the rotation of the twist-lock fixture in the locking channel in a second direction opposite to the first direction, the installed twist-lock fixture can resist one or more of shaking, migration along the locking channel from the original installation position, and / or sliding out of the original installation position. Further, by limiting the rotation of the twist-lock fixture in the locking channel in a second direction opposite to the first direction, the installed twist-lock fixture can resist rotation away from the engaged position, thereby providing a more secure connection. Further, the described twist-lock fixture simplifies component installation and rework. For example, when the described twist-lock fixture is used to guide the component, the component remains in place, which allows installation verification before the component is secured to the twist-lock fixture in a bundle (e.g., using a cable tie).

[0032] First reference Figure 1 , a schematic diagram of a system 100 including a twist-lock fixture 102 is provided. The system 100 (e.g., a modular track mounting system) also includes a workpiece 170 (e.g., a support beam, a housing) and a component 150. The twist-lock fixture 102 includes a body section 110, a mounting section 120, and an object support 130. The object support 130 is configured to mount, support, and / or attach one or more components 150 (e.g., an elongated article, a bundle of elongated articles) to the workpiece 170. One or more of the body section 110, the mounting section 120, or the object support 130 can be integrally formed by an injection molding process or another suitable process and have a suitably resilient material.

[0033] The workpiece 170 may be a support beam of the system 100 that includes a pair of spaced-apart side rails defining a passage (e.g., a mounting hole 172) therebetween (e.g., a longitudinally extending T-slot). The twist-lock fixture 102 is used to attach the component 150 to the workpiece 170 via the mounting hole 172 (e.g., a T-slot) defined in the workpiece 170.

[0034] The body section 110 may include a base, a spring section, etc., and define a recess 112 therein. The mounting section 120 is configured for mounting the twist-lock fixture 102 to the workpiece 170. The mounting section 120 includes a connector 122 configured to facilitate mounting the twist-lock fixture 102 to the workpiece 170. Examples of connectors for the twist-lock fixture 102. Locking fixtures include, but are not limited to, fasteners, fir tree fasteners, blind fasteners, grip fasteners, arrowhead fasteners, mechanical fasteners, twist-lock connectors, and edge clamps. In one example, the connector 122 is a twist-lock connector configured to twist-lock engagement with a mounting hole 172 of the workpiece 170. The connector 122 is configured to be positioned within the mounting hole 172, positioned at a desired location along the length of the mounting hole 172, and then rotated relative to the mounting hole 172 (e.g., a quarter turn, i.e., ninety (90°) degrees) to allow the twist-lock fixture 102 to engage the workpiece 170 (e.g., at a support beam of the workpiece 170), thereby locking the connector 122 in place within the mounting hole 172. In this manner, the position of the connector 122 is configured to move from an unengaged position to a transitional position to a locked position. The connector may be unlocked and repositioned through a repositioning process.

[0035] The mounting section 120 also includes a locking tab 124 (e.g., a twist tab). The locking tab 124 may be a resilient locking tab. The locking tab 124 includes a free end that is configured to extend (e.g., deflect, bend) into a recess 112 defined in the body section 110 (e.g., in a flange of the body section 110) during installation of the twist-lock fixture 102 on the workpiece 170. The recess 112 is configured to receive a portion (e.g., a free end) of the locking tab 124 of the connector 122. After the installation of the twist-lock fixture 102 on the workpiece 170 is completed, the portion of the locking tab 124 is withdrawn (e.g., straightened) from the recess, and the locking tab 124 returns to a normal configuration and restricts rotation of the twist-lock fixture 102 in the mounting hole 172 in a second direction opposite to the first direction. In various aspects, further rotation in the first direction is also restricted. In other words, as the twist-lock fixture 102 is further rotated from the transition position to the locked position, the locking tab 124 straightens and the free end of the locking tab 124 does not extend from the recess 112 of the flange of the body section 110 (eg, retracts).

[0036] The object support 130 can be used to attach the component(s) 150 to the twist-lock fixture 102. Examples of object supports include, but are not limited to, grips (e.g., mounting grips, ratchet P-shaped grips), clamps and other self-securing clamp fasteners (e.g., connector clamps, tying clamps), mounts (e.g., saddle mounts, bracket mounts, cable tie mounts), and the like. The object support 130 can also include a moment arm or other structure configured to space the attachment component 150 from the body section 110. In various aspects, the twist-lock fixture 102 can include no object support. The object support 130 can include a cable tie mount that includes a hole (e.g., a slot) configured to receive a tying material (e.g., a cable tie, a plastic strap, a flexible strap, a metal strap, a string, twine, a silk thread, and the like, collectively referred to herein as a "cable tie") that is used to connect the twist-lock fixture 102 to the component 150. In various aspects, the cable tie is a fastener that is integrally formed with the object support 130 .

[0037] One example of an object support 130 is a bracket mount. The bracket mount is configured to temporarily hold (e.g., secure by a bracket) one or more components (collectively, a "string") near a desired mounting location (e.g., on a workpiece) while the installer is guiding the components (e.g., when the components are being wired). Once the components are guided, the installer can bundle the components together into one or more bundles. In various aspects, the components are bundled using cable ties. In this way, the installer does not need to use temporary bundling materials to create temporary bundles. Instead, the installer can guide all of the components and then apply cable ties to create (one or more) bundles. Doing so avoids the need for the installer to remove temporary bundling materials (e.g., by cutting the cable tie) and add new bundling materials (e.g., adding a new cable tie) for each new component added to the string. This saves time and labor costs.

[0038] Component 150 may include one or more of a channel, a panel, a fixture, an elongated article (eg, a wire, a cable, a hose, a tube, a conduit, a fiber optic cable, a pipe, a harness assembly), etc. Two or more components may be bundled together to form a bundle.

[0039] Reference now Figure 2-10 , a system 200 is shown including a twist-lock fixture 202 and a workpiece 270. Except as described in detail below, the system 200 is similar to Figure 1Thus, the system 200 includes the twist-lock fixture 202, the body section 210, the recess 716, the mounting section 220, the connector 222, the locking tab 410, the object support 330, the workpiece 270, the mounting hole (e.g., the locking channel 272), and the component 390. In various aspects, the twist-lock fixture 202 is configured to be Figure 2 - The unengaged position shown in Figure 4 is rotated ninety degrees (90°) to Fig. 9 and 10 One or more of the body section 210, the mounting section 220, or the object support 330 may be integrally formed by an injection molding process or another suitable process and have a suitably resilient material.

[0040] Figure 2-9 The workpiece 270 shown is of a type that can be used with a modular rail mounting system (e.g., an aluminum T-slot frame system). The modular rail mounting system may include a support beam 274 (e.g., an aluminum extrusion) having a pair of spaced-apart side rails (a first side rail 276, a second side rail 278). The first side rail 276 includes a first arm 277 having a top surface 281 opposite to a bottom surface 285. The second side rail 278 includes a second arm 279 having a top surface 283 opposite to the bottom surface 287. The first arm 277 includes an end 273 and the second arm 279 includes an end 275, the end 273 and the end 275 facing each other. The first side rail 276 and the second side rail 278 define a mounting hole (e.g., a locking channel 272) therebetween. The locking channel 272 can be defined between the end 273 of the first arm 277 and the end 275 of the second arm 279.

[0041] The locking channel 272 defines a longitudinally extending "T-slot" in the support beam 274. In this context, a "T-slot" may include a locking channel 272 having a narrow slot 280 leading to a wide slot 282, wherein the wide slot 282 is wider than the narrow slot 280. The wide slot 282 may be rectangular, circular, half-moon, dovetail, or other shapes. This configuration allows the connector 222 of the twist-lock fixture 202 to pass through the narrow slot 280 into the locking channel 272, wherein the head 240 of the connector 222 freely enters the wide slot 282. In various aspects, the support beam 274 may have an open end (not shown), and the connector 222 may enter the T-slot through the open end rather than through the locking channel 272. In this manner in various aspects, the position of the connector 222 is configured to be from an unengaged position (from Figure 2 -4) Move to the transition position ( Figure 5-8 ), and then to the engaged (eg, locked) position ( Fig. 9 and 10 ).

[0042] The twist-lock fastener 202 includes a mounting section 220 configured to mount the twist-lock fastener 202 on a workpiece 270. Figure 2-10 In the aspect shown in FIG. 2 , the mounting section 220 includes a connector 222 configured to be received in the locking channel 272. The connector 222 may include a rod 224 having a first end 226 opposite a second end 228. The connector 222 may be T-shaped. The connector 222 is configured to be inserted into the locking channel 272 from the end of the support beam 274 and / or through the narrow slot 280 and is used to attach the component (in Figure 3 280) is attached to the support beam 274. In a first example, the connector 222 includes a rod 224 and a head 240, wherein the rod 224 has a width narrower than the narrow slot 280, and the head 240 has a width narrower than the narrow slot 280 in a first dimension and a width wider than the narrow slot 280 in a second dimension. In this configuration, the head 240 can be inserted into the locking channel 272, through the narrow slot 280, and into the wide slot 282. When the head 240 is located in the wide slot 282, the twist-lock fixture 202 can be rotated in a first direction (D1) (e.g., a first rotational direction) to redirect the head 240 from a parallel alignment with the locking channel 272 to a cross alignment that prevents withdrawal of the head 240 from the locking channel 272. The first direction (D1) can be a clockwise direction.

[0043] The head 240 can include at least one shoulder (shoulder 342, shoulder 710) spaced from the flange 212. The shoulder is configured to support the bottom surface (bottom surface 285, bottom surface 287) of the arm (first arm 277, second arm 279) with the flange 212 contacting the top surface (top surface 281, top surface 283) of the arm and a portion of the arm sandwiched therebetween. In this manner, the twist-lock fixture 202 is engaged within the locking channel 272. In various aspects, the shoulder (shoulder 342, shoulder 710) defines a shoulder plane (PS) of the head 240, which can be generally parallel to a flange plane (PF) of the flange 212. In various aspects, the shoulder (shoulder 342, shoulder 710) is orthogonal to the longitudinal axis (L) of the twist-lock fixture 202. For example, the shoulder plane can be orthogonal to the length of the rod 224.

[0044] The head 240 may include at least one ramp (ramp 346, ramp 510) configured to guide the arms (first arm 277, second arm 279) onto the shoulders (shoulder 342, shoulder 710). Through this process, the ramps (ramp 346, ramp 510) may force the head 240 downwardly into the locking channel 272 and create tension in the rod 224, which compresses the twist-lock fixture 202 and the support beam 274 together during installation.

[0045] The connector 222 includes a locking tab 410 (e.g., a twist tab) extending from a first side 436 of the rod 224. The locking tab 410 can be adjacent to only the first side 436 of the rod 224. The locking tab 410 is configured to limit rotation of the twist-lock fixture 202 in the locking channel 272 in a second direction (D2) (e.g., a second rotational direction) when the twist-lock fixture 202 is in the installed position, for example, as Fig. 9 and 10 As shown. The second direction (D2) is opposite to the first direction (D1). The second direction (D2) can be counterclockwise. The locking tab 410 can be flexible and resilient. As used herein, the following terms have the following meanings unless the context clearly indicates otherwise. The term "flexible" refers to an object or material that can be bent, stretched, or compressed without cracking or breaking. The term "elastic" is used to define the flexible characteristic as generally returning to an initial general shape after bending, stretching and / or compression without permanent deformation.

[0046] The locking tab 410 includes a free end 412 spaced apart from the rod 224. The locking tab 410 is configured to bend and extend (e.g., deflect) upward (e.g., in an upward direction) to position the free end 412 in a recess 716 (e.g., a gap) defined in the flange 212, such as Figure 6-8 As used herein, the terms "upward" and "upward direction" refer to a direction toward the flange 212 and away from the head 240. The recess 716 is configured to receive the locking tab 410 or a portion thereof (e.g., a portion of the free end 412). The recess 716 faces the head 240. The recess 716 can define a top 702 and the locking tab 410 (e.g., a portion of the free end 412) can contact the top 702 of the recess 716. The locking tab 410 can be spaced apart from the shoulder (shoulder 342, shoulder 710) and can extend axially from the rod 224 generally parallel to the shoulder plane (PS). The locking tab 410 can extend from the rod 224 orthogonal to the longitudinal axis (L) of the twist-lock fixture 202.

[0047] The body section 210 can be attached to the connector 222 at the first end 226 of the rod 224. The body section 210 includes a flange 212 configured to contact a first side of the workpiece 270 to limit the longitudinal insertion of the connector 222 into the locking channel 272. The flange 212 includes an underside 214 facing the head 240. The underside 214 of the flange 212 includes a recess 716 defined therein.

[0048] Figure 2-4A and Figure 5-9 The installation sequence of the twist-lock fixture 202 in the locking channel 272 of the support beam 274 is shown. Figure 2 2 is an exploded side view showing the system 200 including the twist-lock fixture 202 and the support beam 274 . Figure 3 and 4A The twist-lock fastener 202 is shown positioned in the locking channel 272 in an inserted but unengaged position. In the unengaged position, the locking tab 410 extends from the first side 436 of the rod 224. In this position, the locking tab 410 can extend generally parallel to the longitudinal axis of the side rails (first side rail 276, second side rail 278). The twist-lock fastener 202 is configured to rotate in a first direction (D1) relative to the longitudinal axis (L) of the twist-lock fastener 202, such as Figure 4A As shown. Figure 3 and Figure 4A , the twist-lock fixture 202 is configured to rotate in a first direction ( D1 ) relative to a longitudinal axis (L) of the twist-lock fixture 202 . Figure 4B A bottom view of the twist-lock fixture 202 is shown.

[0049] exist Figure 3 , twist-lock fixture 202 is shown as including an object support 330 (e.g., object support 130 described above) configured to support a component 390 (e.g., component 150 described above). For example, object support 330 can be configured to attach component 390 to workpiece 270. Object support 330 and component 390 are shown in phantom.

[0050] exist Figure 4A 2, the locking tab 410 is in a normal configuration. In the normal configuration, the locking tab 410 has an initial overall shape and can extend orthogonally from the rod 224. In various aspects, the side of the locking tab 410 can include a cutout (e.g., a recessed portion 414) that is configured to be spaced apart from the end 275 of the second arm 279. The recessed portion 414 provides a gap between the locking tab 410 and the end 275 and / or the second arm 279, which enables an initial unrestricted initial rotation.

[0051] like Figure 4A and 6 As shown, the rod 224 may include at least one cam surface (e.g., cam surface 302) configured to rotate against the ends (ends 273, 275) of the corresponding arms (first arm 277, second arm 279) during the rotation of the twist-lock fixture 202 in the locking channel 272. The rod 224 may include a first stop 230 configured to limit the rotation of the connector 222 in the locking channel 272 along the first direction (D1). The first stop 230 may be configured to stop against the end 273 of the first arm 277 of the support beam 274 (e.g., as shown in FIG. 2A ). Fig. 9 and 10). In this manner, the first stop 230 can limit further rotation of the twist-lock fixture 202 in the first direction (D1) within the locking channel 272. The first stop 230 can be a slight acute angle that interferes with the locking channel 272, which extends along the entire length of the rod 224 adjacent the second side 234 of the rod 224.

[0052] Figure 5 is in the first rotation position Figure 2 A partial side view of the system 200, and Figure 6 is in the first rotation position Figure 5 A top view of the system 200 taken along line 6-6 is shown. Figure 5 and 6 , the twist-lock fixture 202 has been rotated in a first direction (D1) relative to the longitudinal axis (L) of the twist-lock fixture 202 (e.g., sixty degrees (60°)). The end 412 has contacted the end 275 of the second arm 279. In the illustrated aspect, the end 275 is rounded, and the free end 412 tangentially contacts the rounded end 275 and slides upward when the locking tab 410 is dragged along the rounded end. When the twist-lock fixture 202 is rotated in the first direction, the friction between the locking tab 410 and the surface of the second arm 279 provides resistance (e.g., a drag force). In this way, the locking tab 410 flexes in an upward direction, bending toward the flange 212, thereby causing the locking tab 410 to be in a bent configuration. In the bent configuration, the free end 412 of the locking tab 410 can extend (e.g., bend) out of the mounting hole (e.g., the locking channel 272) and can extend (e.g., bend) into the recess 716. The bottom surface 287 of the second arm 279 contacts and moves the inclined surface 346 upward. Similarly, the bottom surface 285 of the first arm 277 contacts and moves the inclined surface 510 upward. As a result, the first arm 277 and the second arm 279 are compressed between the lower side 214 of the flange 212 and the inclined surface 346 and the inclined surface 510, respectively.

[0053] Figure 5 and 6 The head 240 of the twist-lock fixture 202 is shown positioned in the wide slot 282 in a first rotational position. In the first rotational position, the twist-lock fixture 202 has been partially rotated in a first direction (D1) relative to the longitudinal axis (L) of the twist-lock fixture 202. During the rotation, as shown in FIG. Figure 6 As shown, the free end 412 of the locking tab 410 contacts the second arm 279 of the second side rail 278 and flexes upward. In this way, the locking tab 410 rides on the upper surface of the second arm 279. When the fixing member 202 is fixed in the locking channel 272, the cam surface 302 can be rotated against the end 273 of the first arm 277.

[0054] During rotation of the twist-lock fixture 202 in the first direction (e.g., from the unengaged position and through the transition position), the bottom surface 285 of the first arm 277 can ride on the ramp 346. Figure 5 and 6 As shown, the bottom surface 287 of the second arm 279 can ride on the ramp 510. When the arm (first arm 277, second arm 279) rides on the ramp (ramp 346, ramp 510), the arm (first arm 277, second arm 279) can be compressively fitted between the head 240 (e.g., the ramp 346 of the head 240, the ramp 510 of the head 240) and the lower side 214 of the flange 212. This may cause significant resistance while rotating. The space between the shoulder (shoulder 342, shoulder 710) and the flange 212 can be narrower than the thickness of the arm (first arm 277, second arm 279), and the ramp (ramp 346, ramp 510) can be configured to allow the thicker arm (first arm 277, second arm 279) to rotate between the shoulder (shoulder 342, shoulder 740) and the flange 212. The narrower space (e.g., gap) can (a) provide a mechanical advantage, resulting in less hand force required to fully rotate and install the twist-lock fixture 202, (b) wedge the arms (first arm 277, second arm 279) between the shoulders (shoulder 342, shoulder 740) and the flange 212, (c) secure the connector 222 tightly to the locking channel 272 and / or workpiece 270 without shaking, and / or (d) prevent the connector 222 from rotating and migrating along the locking channel 272 and / or workpiece 270. When the connector 222 is in compression, (e) the rod 224 can be in tension. When the connector 222 is in compression, (f) the body segment 210 can be as shown. Fig. 12A The bending is shown as deflection (D) relative to the twist-lock fixture 1202. Natural deflection / bending of the body segment 210 may occur when the twist-lock fixture 202 is installed in the locking channel 272. Features (e) and (f) may help provide features (b), (c), and / or (d) listed above.

[0055] When the arms (first arm 277, second arm 279) ride on the ramps (ramp 346, ramp 510), the arms can compressively fit between the ramps (ramp 346, ramp 510) and the underside 214 of the flange 212. This can cause significant resistance while rotating. In the transition position and / or in the locked position, the arms (first arm 277, second arm 279) of the workpiece 270 can be compressively received between the head 240 (e.g., the shoulder 342 of the head 240, the shoulder 710 of the head 240) and the flange 212. The compression fit can resist at least one of rotational movement of the twist-lock fixture 202 in the locking channel 272 in a first direction; rotational movement of the twist-lock fixture 202 in the locking channel 272 in a second direction opposite to the first direction; or movement of the twist-lock fixture 202 along the locking channel 272. The compression fit can also cause the body segment 210 (e.g., the outer portion of the flange 212, which is opposite the rod 224) to flex and the rod 224 to remain in tension, which can cause the connector 222 to be tightly held on and / or within the locking channel 272, thereby limiting the migration of the connector 222 in the locking channel 272. The twist-lock fixture 202 can also be configured to rotate from the locked position back to the transition position by applying a rotational force in a second direction opposite to the first direction. Rotating from the locked position back to the transition position can cause the locking tab 410 to bend and can cause the free end of the locking tab 410 to extend into the recess 716 of the flange 212.

[0056] Figure 7 is in the second rotation position Figure 2 A partial side view of the system 200. Figure 5 and Figure 6 Compared with the aspects shown in Figure 7 , the twist-lock fixture 202 has been rotated a plurality of additional angles (e.g., fifteen degrees (15°)) in the first direction (D1) relative to the longitudinal axis (L) of the twist-lock fixture 6. In this view, the free end 412 continues to traverse the second arm 279 and bends further into the recess 716. In various aspects, the locking tab 410 (e.g., the free end 412) can be compressed between the top 702 of the recess 716 and the surface of the arm (e.g., the second arm 279).

[0057] The rod 224 may include a second stop 630 configured to limit rotation of the connector 222 in the locking channel 272 in at least one of the first direction (D1) or the second direction (D2). The second stop 630 may be configured to stop against the end 275 of the second arm 279 of the support beam 274 (e.g., as shown in FIG. Fig. 9 and 10). In this manner, the second stop 630 can limit further rotation of the twist-lock fixture 202 in the locking channel 272 in the first direction (D1). The locking tab 410 can be positioned between the first stop 230 and the second stop 630. The locking tab 410 and the second stop 630 can be similar in size and position.

[0058] As rotation continues, the free end 412 extends (eg, extends, deflects, bends, is deflected) into the recess 716, as shown in FIG. Figure 7 shown. Figure 7 The head 240 of the twist-lock fixture 202 is shown positioned in the wide slot 282 in a second rotational position. In the second rotational position, the twist-lock fixture 202 has been further rotated in the first direction (D1) relative to the longitudinal axis (L) of the twist-lock fixture 202.

[0059] exist Figure 7 , the second stopper 630 has rotated into view. At least one stopper (e.g., the first stopper 230, the second stopper 630) is configured to limit the rotation of the connector 222 in the locking channel 272 along the first direction (D1). For example, the stopper (the first stopper 230, the second stopper 630) may be configured to stop against the ends (end 273, end 275) of the arms (the first arm 277, the second arm 279) of the support beam 274, such as Fig. 9 and 10 In this manner, the first stop 230 and / or the second stop 630 can limit further rotation of the twist-lock fixture 202 in the locking channel 272 along the first direction (D1). Figure 4A shown.

[0060] As the rotation continues further, the free end 412 continues to extend into the recess 716, as shown in FIG. Figure 8 shown. Figure 8 The head 240 of the twist-lock fixture 202 is shown positioned in the wide slot 282 in a third rotational position. In the third rotational position, the twist-lock fixture 202 has been further rotated in the first direction (D1) relative to the longitudinal axis (L) of the twist-lock fixture 202. The locking tab 410 may contact the top 702 of the recess 716. Figure 7 and 8 In the embodiment of the present invention, the locking tab 410 can be compressed between the top 702 and the surface of the arm (e.g., the second arm 279).

[0061] The connector 222 includes a head 240 extending from the second end 228 of the rod 224. The head 240 is designed to be narrower than the narrow slot 280 in a first dimension so that the head 240 can pass through the narrow slot 280 and enter the wide slot 282. The head 240 is further designed to be wider than the narrow slot 280 in a second dimension so that the head 240 can resist the withdrawal of the connector 222 from the locking channel 272 when in the installed position. This configuration allows the connector 222 of the twist-lock fixture 202 to pass through the narrow slot 280 and enter the locking channel 272, wherein the head 240 of the connector 222 freely enters the wide slot 282. In various aspects, the support beam 274 can have an open end (not shown), and the connector 222 can enter the T-slot through the open end instead of through the locking channel 272. The rod 224 includes a second side 234 opposite the first side 436. The first stop 230 can extend from the second side 234 of the rod 224. The twist-lock fixture 202 can include a second stop 630 extending from the first side 436 of the rod 224. The second stop 630 can be spaced apart from the locking tab 410. The first stop 230 and / or the second stop 630 can be configured to limit rotation of the twist-lock fixture 202 in the locking channel 272 in the first direction (D1).

[0062] Figure 8 is in the third rotational position Figure 2 A partial side view of the system 200. Figure 7 Compared with the aspects shown in Figure 8 , the twist-lock fixture 202 has been rotated a plurality of additional angles (e.g., ten degrees (10°)) in the first direction (D1) relative to the longitudinal axis (L) of the twist-lock fixture 6. At this point, the distance between the end 275 and the rod 224 increases, allowing the locking tab 410 to partially straighten, while the amount of the free end 412 extending into the recess 716 decreases.

[0063] Fig. 9 is in the engaged position Figure 2 A partial side view of the system 200, and Fig.10 is in the engaged position Fig. 9 A top view of the system 200 taken along line 10-10. Figure 8 Compared with the aspects shown in Fig. 94, the twist-lock fixture 202 has been rotated in the first direction (D1) by a plurality of additional angles (e.g., five degrees (5°)) relative to the longitudinal axis (L) of the twist-lock fixture 202 (e.g., ninety degrees (90°) relative to the longitudinal axis (L) of the twist-lock fixture 202 in the first direction (D1) compared to the aspect shown in FIG. 4). At this point, the distance between the end 275 and the rod 224 is greater than the length of the locking tab 410, thereby providing a gap that allows the locking tab 410 to elastically straighten (e.g., straighten) and transition from the bent configuration to the normal configuration. In various aspects, the locking tab 410 can quickly return to the normal configuration. In the normal configuration, the locking tab 410 limits and / or prevents the twist-lock fixture 202 from rotating in the locking channel 272 in a second direction (D2) opposite to the first direction (D1). As a result, the locking tab 410 locks the angular position of the twist-lock fixture 202 relative to the support beam 274 in the locked position. Low hand force can be used to pull the connector out of the unengaged position ( Figure 2 and 3 ) rotates through the transition position ( Figure 4A-8 ), and into the locked position ( Fig. 9 and 10 ); Conversely, moderate hand force can be used to move the connector from the locked position (as shown in Fig. 9 and Fig.10 ) rotates back to the transition position (as shown) Figure 8 shown).

[0064] In the Fig. 9 and 10 After the locking position shown in which the locking tab 410 is straight, the locking tab 410 can be further configured to flex upward when sufficient rotational force (e.g., moderate hand force) is applied in the second direction (D2). The locking tab 430 can provide forced flexibility to attempt to bend back into the recess 716 (e.g., as from the recess 716) when a rotational force (e.g., moderate hand force, (e.g., moderate hand force, ninety degree (90°) rotation) is applied in the second direction (D2). Fig. 9 Back to Figure 8 ), the rotational force overcomes the vertical compressive contact of the free end 412 rotating against the inner width track (e.g., end 273, end 275) of the locking track 272. In other aspects, the second stop 630 can be abutted by two sides (e.g., the first side 436 of the rod 224 and the engaging surface of the T-shaped connector (e.g., shoulder 710)), which together can be considered "rigid" relative to flexibility.

[0065] Reference now Fig.11A , 11Band 11C , show a system 1100 including a twist-lock fixture 1102 , a workpiece 1170 , and a component 1190 , the twist-lock fixture 1102 being configured to be attached to the workpiece 1170 . Fig.11A is a front perspective view of the twist lock fixture 1102, Fig. 11B is a rear perspective view of the twist lock fixture 1102, Fig. 11C is a side view of a twist lock fixture 1102 mounted to a workpiece 1170. Except as described in detail below, the system 1100 is similar to Figure 1 and Figure 2 Thus, system 1100 includes twist-lock fixture 1102, body section 1110, recess 1112, mounting section 1120, connector 1122, locking tab 1124, rod 1126, object support 1130, head 1128, workpiece 1170, locking channel 1172, support beam 1174, narrow slot 1180 and wide slot 1182, and component 1190.

[0066] In twist-lock fixture 1102, object support 1130 is a bracket-mounted object support that includes a bracket portion 1132 configured to receive, secure, and / or support one or more components (e.g., component(s) 1190). System 1100 may also include one or more cable ties 1176 for bundling components 1190 and / or retaining a bundle of one or more components to object support 1130.

[0067] Bracket portion 1132 is shown as having a bracket geometry including a support member 1134 and at least one receiving arm (receiving arm 1136, receiving arm 1138). Support member 1134 is configured to space at least one receiving arm (receiving arm 1136, receiving arm 1138) from body section 1110 to define at least one bracket 1140 therebetween. Receiving arms (receiving arms 1136, receiving arms 1138) are configured to retain component 1190 (e.g., a bundle) in bracket 1140. In various aspects, the receiving arms can be hook-shaped and / or can include one or more retaining cleats extending from one end of the receiving arms and extending toward bracket 1140 for retaining component 1190 in bracket 1140.

[0068] Bundles of components can be tightly bound (compressed) with cable ties. For example, Fig.11A and 11BIn the illustrated aspect, the cable tie 1176 extends through a tie channel 1166 (e.g., a tie slot) that passes through the body segment 1110, around the seat member 1134, and is defined on a component 1190 held in the bracket 1140 of the bracket portion 1132. In such circumstances, it may be difficult to cut the cable tie 1176 without damaging (e.g., scoring) one or more components in the bundle. The twist-lock fixture 1102 may include at least one cutting guide 1160 configured to support the cable tie 1176 spaced apart from the twist-lock fixture 1102 and configured to receive a cutting tool (not shown) therein. The cutting guide 1160 includes features and / or geometries configured to protect the elongated article from damage when severing the cable tie 1176 attached to the bundle held in the bracket portion 1132 of the twist-lock fixture 1102. The cutting guide 1160 can be directed through a recess defined in the bracket portion 1132 of the twist-lock fixture 1102. Fig.11A and 11B In the illustrated aspect, the cutting guide 1160 includes a first flange 1162 spaced apart from a second flange 1164, the first flange 1162 defining a cutting region therebetween. The cutting region forms a guide for an installer using a cutting device (e.g., diagonal pliers tool, wire cutters, side cutters) to remove the cable tie from the bundle (e.g., to guide the sharp end of the installer's diagonal pliers against the cable tie while applying a cutting force to the handles of the diagonal pliers). In this manner, damage to a component (e.g., an elongated article) is prevented when the cable tie is removed (e.g., by cutting).

[0069] The mounting section 1120 is configured for mounting the twist-lock fixture 1102 on the workpiece 1170. The mounting section 1120 includes a connector 1122 configured to be received into a locking channel 1172 of the workpiece 1170. The connector 1122 may be T-shaped and include a stem 1126 and a head 1128. The connector 1122 is configured to be inserted into the locking channel 1172 through the narrow slot 1180 and used to attach the component 1190 to the support beam 1174. The connector 1122 includes a stem 1126 and a head 1128, wherein the stem 1126 has a narrower width than the narrow slot 1180, and the head 1128 has a narrower width than the narrow slot 1180 in a first dimension and a wider width than the narrow slot 1180 in a second dimension. In this configuration, the head 1128 can be inserted into the locking channel 1172, through the narrow slot 1180, and into the wide slot 1182. With the head 1128 positioned in the wide slot 1182, the twist-lock fixture 1102 can be rotated in a first direction to redirect the head 1128 from a parallel alignment with the locking channel 1172 to a cross alignment that prevents the head 240 from being withdrawn from the locking channel 1172, as shown. Fig. 11C shown.

[0070] The head 1128 may include a compressible portion 1148 configured to collapse (e.g., a void defined within the head 1128). The compressible portion 1148 may be configured to compress when the end of the head 1128 contacts the bottom 1186 of the locking channel 1172. The compressible portion 1148 may be elastic. By compression of the compressible portion 1148 of the head 1128, tension may be generated in the rod 1126, which compresses the twist-lock fixture 1102 and the support beam 274 together during installation. The head 1128 may also include a rotating pad 1154 configured to rotate in engagement with a surface (e.g., the bottom 1186) within the locking channel 1172. The rotating pad 1154 may serve as a reinforcement for the head 1128.

[0071] Now refer to Fig. 12A , Fig. 12B and Fig. 12C , illustrating additional aspects of a twist-lock fixture 1202 that may be used in a system including a workpiece (eg, workpiece 170 , workpiece 270 , workpiece 1170 , workpiece 1270 ) and a component (eg, component 190 , component 290 , component 1190 ). Fig. 12A is a partial side view of the twist lock fixture 1202, Fig. 12B is a partial perspective view of twist lock fixture 1202, and Fig. 12C 1 is a partial side view of a system 1200 having a twist-lock fixture 1202 and a workpiece 1270, wherein the twist-lock fixture 1202 is shown in a rotated position. The twist-lock fixture 1202 is configured to be attached to the workpiece 1270. Except as described in detail below, the system 1200 is similar to the systems described above and shown in the figures (system 100, system 200, system 1100). Thus, system 1200 includes a twist-lock fixture 1202, a body section 1210, a flange 1212, an underside 1214, a recess 1216, a mounting section 1220, a connector 1222, a locking tab 1224, a rod 1226, a head 1227, shoulders (shoulder 1228, shoulder 1229), an object support (not shown), ramps (ramp 1246, ramp 1248), a workpiece 1270, a locking channel 1272, arms (first arm 1277, second arm 1279) and components (not shown).

[0072] exist Figures 12A-12CIn the illustrated aspect, the space between the shoulders (shoulder 1228, shoulder 1229) and the flange 1212 can be narrower than the thickness of the arms (first arm 1277, second arm 1279), and the ramps (ramp 1246, ramp 1248) can be configured to allow the thicker arms (first arm 1277, second arm 1279) to rotate between the shoulders (shoulder 1228, shoulder 1229) and the flange 1212. The narrower space (e.g., gap) can (a) provide a mechanical advantage, resulting in less hand force required to fully rotate and install the twist-lock fastener 1202 (e.g., as described above with respect to Figure 2-10 (a) the arms (first arm 1277, second arm 1279) are wedged between the shoulders (shoulder 1228, shoulder 1229) and the flange 1212, (c) the connector 1222 is fixed tightly to the locking channel 1272 and / or the workpiece 1270 without shaking, and / or (d) the connector 1222 is prevented from rotating and migrating along the locking channel 1272 and / or the workpiece 1270. When the connector 1222 is in a compressed state, (e) the rod 1226 can be in a tensioned state. When the connector 1222 is in a compressed state, (f) the body section 1210 can be as Fig. 12A The bending shown is deflection (D). When the twist-lock fixture 1202 is installed in the locking channel 1272, natural deflection / bending of the body segment 1210 may occur. Features (e) and (f) may help provide features (b), (c), and / or (d) listed above. When the arms (first arm 1277, second arm 1279) ride on the ramps (ramp 1246, ramp 1248), the arms (first arm 1277, second arm 1279) may compressively fit between the head 1227 (e.g., ramp 1246 of the head 1227, ramp 1248 of the head 1227) and the underside 1212 of the flange 1214. This may cause significant resistance while rotating.

[0073] In the transition position and / or in the locked position, the arms (first arm 1277, second arm 1279) of the workpiece 1270 are compressibly received between the head 1227 (e.g., the shoulder 1228 of the head 1227, the shoulder 1229 of the head 1227) and the flange 1212. The compression fit can resist at least one of rotational movement of the twist-lock fixture 1202 in the locking channel 1272 in a first direction; rotational movement of the twist-lock fixture 1202 in the locking channel 1272 in a second direction opposite to the first direction; or movement of the twist-lock fixture 1202 along the locking channel 1272. The compression fit can also cause the body segment 1210 (e.g., the outer portion of the flange 1212, which is opposite the rod 1226) to flex and the rod 1226 to remain in tension, which can cause the connector 1222 to be tightly held on and / or within the locking channel 1272, thereby limiting migration of the connector 1222 in the locking channel 1272.

[0074] The twist-lock fixture 1202 can also be configured to rotate from the locked position back to the transition position by applying a rotational force in a second direction opposite to the first direction. Rotating from the locked position back to the transition position can cause the locking tab 1224 to bend and can cause the free end of the locking tab 1224 to extend into the recess 1216 of the flange 1212.

[0075] The amount of compression of the connector 1222 on the arms (arms 1277, 1279) can be controlled in part by including an adjacent rib 1215 positioned between the flange 1212 and the rod 1226. The size and length of the rib 1215 can affect the rigidity and reinforcement that the rib 1215 provides to the body segment 1210. The rib 1215 may not eliminate the deflection and / or bending of the body segment 1210, but the rib 1215 can change and / or redistribute the contact force that occurs between the twist-lock component and the arm that engages the locking channel 1272 (first arm 1277, second arm 1279). The addition of the rib 1215 can increase the compressive force on the arms (first arm 1277, second arm 1279) by a percentage amount that is proportional to the size and length of the rib 1215. The increased compressive force provides increased retention strength to prevent the connector 1222 from shaking, rotating, and / or moving along the locking channel 1272. Connecting ribs 1215 from flange 1212 to rod 1226 may enhance support for rod 1226 . Material

[0076] The components of the disclosed twist-lock fastener may be made of any suitable resilient material, including polymeric materials. Suitable polymeric materials may include one or more of polyamide, polyamide 6.6, nylon 6, nylon, polypropylene, polyphenylene sulfide (PPS), and the like, and polymers thereof. Additional Examples
