Embodiments of the present disclosure generally relate to fastener assemblies, and more particularly to compensation nut fastener assemblies that are configured to accommodate gaps between components, such as panels.
In various industrial applications, components are connected together through the use of fasteners. In some applications, a gap may exist between the components. For example, two panels may be separated by a clearance area or gap in which portions of other components may reside. When connecting the panels together, a fastener assembly may rattle or slip within the gap, thereby generating undesired noise and providing a loose connection.
Additionally, fasteners may be welded to components in order to provide a secure connection between the components. However, welding may be labor and time intensive, thereby adding time and cost to a manufacturing process.
Some fastener assemblies employ a torque clip, which may include a body configured to be inserted into a fastener-receiving channel of a nut. The main body may be tubular, having one or more longitudinal recesses formed therein. The torque clip is configured to center and hold a fastener, such as a bolt or screw, as the fastener is inserted into the fastener-receiving channel. The torque clip ensures that the fastener remains in place and does not dislodge from the nut. The torque clip may be a plastic sleeve used to grip a fastener during an installation process. A known torque clip is described in U.S. Pat. No. 5,395,194, entitled “Convoluted Bolt Retainer,” which is hereby incorporated by reference in its entirety.
In known assemblies, a torque clip is susceptible to slipping within a top nut when a bolt (or other such fastener) threadably engages the fastener assembly. Further, when the bolt is removed from the fastener assembly, the torque clip is susceptible to being removed along with the bolt. For example, as the bolt is pulled out of a nut, the torque clip may remain connected to the bolt and may be pulled out of the nut along with the bolt. Also, known compensation nut fastener assemblies typically include a separate and distinct O-ring that is used to prevent the top nut from jamming with a bottom nut.
Accordingly, a need exists for a reliable and robust torque clip that is configured to be used with a compensation nut fastener assembly.
Certain embodiments of the present disclosure provide a compensation nut fastener assembly that may include a first nut including a first channel, a second nut including a second channel configured to receive a portion of the first nut, and a torque clip including at least one securing member radially extending from the shaft. The shaft is securely fixed within the first channel. The securing member(s) may include a fixing clip that securely fixes the torque clip to the first nut, and an offset tab that defines a minimum offset distance between the first nut and the second nut.
The fixing clip prevents the torque clip from rotating in relation to the first nut. Also, the fixing clip prevents the torque clip from dislodging from the first nut when a fastener is removed from the compensation nut fastener assembly.
The securing member(s) may also include an extension beam connected to the fixing clip and the offset tab. In at least one embodiment, the fixing clip includes a ramped surface connected to a ledge. The ledge is configured to securely hook onto a portion of the first nut. The offset tab may be configured to abut into an edge of the second nut. In at least one embodiment, a first securing member is linearly aligned with a second securing member.
The first nut may include a collar having a recessed track formed therein. The securing member(s) may be retained within at least a portion of the recessed track. At least one opening may be formed through the recessed track. The fixing clip and the offset tab may extend through the opening(s).
In at least one embodiment, the second nut may include a panel-engaging member. For example, the panel-engaging member may be resilient tabs, stanchions, posts, studs, clips, and/or the like.
Certain embodiments of the present disclosure provide a torque clip configured to be securely fixed to a first nut of a compensation nut fastener assembly. The torque clip may include a shaft, and at least one securing member radially extending from the shaft. The main body may be securely fixed within the first channel. The securing member(s) may include a fixing clip configured to securely fix the torque clip to the first nut, and an offset tab that defines a minimum offset distance between the first nut and the second nut.
Before the embodiments of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use of “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
Embodiments of the present disclosure provide a compensation nut fastener assembly that may include a torque clip having one or more securing members configured to securely connect the torque clip to a nut. Each securing member may include a fixing clip that is configured to securely fix the torque clip to the nut, and an offset tab that is configured to maintain a minimum offset between the nut and another nut. The fixing clip securely and reliably fixes the torque clip to the nut in order to prevent the torque clip from spinning or otherwise rotating within the nut, and prevent the torque clip from being removed from the nut when a fastener (such as a bolt) is removed from the compensation nut fastener assembly. The offset tab provides a feature that is configured to prevent connected components from jamming. For example, an anti-jam feature may prevent first and second nuts from being over-threaded with respect to one another. The anti-jam feature eliminates, minimizes, or otherwise reduces a need for a separate and distinct O-ring.
As shown, the assembly 100 includes a first nut 110 and a second nut 112. A torque clip 300, such as described below, may be secured to the first nut 110. The second nut 112 may include panel-engaging members, such as stanchions 114, which may be configured to be securely retained within reciprocal features of the panel 104. In general, the first nut 110 may threadably secure to the second nut 112. The second nut 112 may directly connect to the panel 104 through the stanchions 114. Alternatively, the second nut 112 may include various other types of panel-engaging members.
A fastener 106 is urged in the direction of arrow 107 into a fastener-receiving channel 108 of the torque clip 300, which is retained within a channel of the first nut 110. The torque clip 300 may be securely locked or otherwise fixed in position with respect to the first nut 110, such as through one or more securing members, as described below. The torque clip 300 may be configured to threadably receive and retain the fastener 106. As the fastener 106 is torqued or rotated into a securing engagement with the first nut 110, the first nut 110 is drawn toward a head 120 of the fastener 106.
A fastener 214 may include a shaft 216 inserted through a hole 218 of the panel 202. The fastener 214 threadably engages the torque clip 300 securely fixed to the first nut 206. As the fastener 214 is torqued in relation to the first nut 206 in the direction of arc 220, the fastener 214 moves into the assembly 200 in the direction of arrow 222. At the same time, the first nut 206 extends or otherwise moves toward the panel 202 in the direction of arrow 224, which is opposite from the direction of arrow 222. As such, the first nut 206 extends into a bracing position with the panel 202, so that the compensation nut fastener assembly 200 is securely braced within a gap 226 between the panels 202 and 204. As such, the bracing relationship of the compensation nut fastener assembly 200 within the gap 226 prevents the assembly 200 from shifting or rattling.
The main body 302 may include a shaft 306 that extends from a first end 308 (such as a top end) to an opposite second end 310 (such as a bottom end). A fastener channel 312 is formed through the shaft 306 from the first end 308 to the second end 310. The fastener channel 312 is configured to receive a fastener, such as a bolt. In at least one embodiment, at least portions of internal surfaces 314 of the shaft 306 that define the fastener channel 312 may be threaded in order to threadably engage threaded portions of the fastener.
As shown, the shaft 306 may include regularly-spaced outwardly bowed walls 316 that are configured to abut into internal walls of a nut. The bowed walls 316 may be separated by inwardly-recessed walls 318. Alternatively, the shaft 306 may be formed as various other shapes. For example, the shaft 306 may be formed as a cylindrical tube.
Each securing member 304 may be or include an arm, wing, beam, strap, panel, or the like radially and outwardly extending from the first end 308 of the shaft 306. Top surfaces of the securing members 304 may be flush with an upper edge of the first end 308. Each securing member 304 may include an extension beam 320 radially extending from the first end 308. A fixing clip 322 may downwardly extend from a distal end 324 of the extension beam 320. A supporting or offset tab 326 may downwardly extend from the extension beam 320 inboard from the fixing clip 322. For example, the supporting or offset tab 326 may be closer to the shaft 306 than the fixing clip 322.
The torque clip 300 may include two linearly aligned securing members 304. For example, the securing members 304 may be linearly aligned along a central axis 328 of the torque clip 300. Alternatively, the torque clip 300 may include more or less securing members 304 than shown. For example, the torque clip 300 may include three or more securing members 304. In at least one other embodiment, the torque clip 300 may include only one securing member 304.
Each fixing clip 322 may include a beam 330 that downwardly extends from the extension beam 320 at a right angle. A distal end 332 of each fixing clip 322 may include a ramped outer surface 334 that connects to a ledge 336 that may be parallel with the extension beam 320.
Each supporting or offset tab 326 may be a flat, planar beam that downwardly extends from the extension beam 320 at a right angle. As shown, the offset tab 326 may be inboard (that is, closer to the shaft 306) from the fixing clip 322. In operation, the offset tabs 326 provide a bracing support between first and second nuts that prevents jamming of the nuts and components secured thereto. Alternatively, the torque clip 300 may not include the offset tabs 326. In at least one another embodiment, the offset tabs may be configured as additional fixing clips (such as the fixing clips) to provide increased retaining strength with respect to a nut.
The compensation nut fastener assembly 400 may include a first nut 402 and a second nut (hidden from view in
The tube 410 of the first nut 402 is configured to be received and retained within a channel 412 of a second nut 414. The channel 412 is defined by an outer circumferential wall 416 having an upper edge 418.
The collar 404 of the first nut 402 may include openings 419 formed therethrough. The openings 419 are configured to allow the fixing clip 322 and the offset tab 326 of the securing members 304 to pass therethrough. In at least one embodiment, each openings 419 may be slightly wider than the fixing clips 322 and the offset tabs 326 in order to allow the fixing clips 322 and the offset tabs 326 to pass into the openings 419 (such as through an interference fit), and prevent rotation of the torque clip 300 in relation to the first nut 402. As the fixing clips 322 pass through the openings 419, the ramped over surfaces 334 slide over outboard internal edges 420 that partially define the openings 419 and deflect inwardly until the ledges 336 engage lower surfaces of the collar 404, thereby allowing the securing members 304 to flex back to their at rest positions, and snapably secure the securing members 304 (and therefore the torque clip 300) into a secure fixed position in relation to the first nut 402.
The offset tabs 326 extend through the openings 419 and abut into the upper edges 418 of the second nut 414, thereby defining a minimum offset distance between the first nut 402 and the second nut 414. For example, the offset tabs 326 bottom out on the upper edges 418, thereby defining a minimum offset distance between the collar 404 of the first nut 402 and the upper edges 418 of the second nut 414. In this manner, the offset tabs 326 provide bracing offsets that prevent or otherwise reduce the possibility of the first and second nuts 402 and 414 jamming. The offset tabs 326 are configured to bottom out on the upper edges 418 of the second nut 414 to prevent the first nut 402 from over-threading onto the second nut 414.
The offset tabs 326 abut into the upper edges 418 of the second nut 414, which bracingly offsets the first nut 402 from the second nut 414. As such, the offset tabs 326 provide anti jam features that prevent the first nut 402 from being over-torqued in relation to the second nut 414. That is, the offset tabs 326 engage the upper edges 418 to provide a minimum offset between the first and second nuts 402 and 414.
The offset tabs 326 may be shorter or longer than shown. In general, the offset tabs 326 may be sized based on a desired minimum separation between the collar 404 of the first nut 402 and the upper edge 418 of the second nut 414.
The upper surfaces of the extension beams 320 may be flush with an upper surface of the collar 404. The recessed track (shown in
The torque clip 300 applies torque to the first nut 402. When the torque clip 300 is locked in place with respect to the nut 402, such as through the fixing clips 322, the torque clip 300 is prevented from rotating or otherwise spinning within the first nut 402. Further, the fixing clips 322, for example, ensure that the torque clip 300 remains within the first nut 402 when a bolt or other such fastener is removed from the compensation nut fastener assembly 400.
The offset tabs 326, which provide an anti jam feature, ensures a minimum offset distance between the first nut 402 and the second nut 414, thereby preventing any jamming/locking of parts when the first nut 402 is secured to the second nut 414. The offset tabs 326 eliminate the need for a separate and distinct O-ring, such as found in known compensation nut fastener assemblies, which were previously used to prevent jamming.

The panel-engaging member 506 may also include a downwardly-extending stud 514 that is configured to be received within a reciprocal hole of a component. The stud 514 may define a threaded internal passage that is configured to threadably engage a threaded portion of a shaft of a bolt, for example.
