Reusable nut configured to be fixed within hole in component and to become part of assembly with the component

Abstract

A nut is configured to be secured within a hole in a component. The nut includes an inner polygonal body, an outer polygonal body, and a pair of arms connecting the inner and outer polygonal bodies to one another. The arms allow the inner polygonal body to move relative to the outer polygonal body from a first position, in which a majority of the inner polygonal body is disposed outside of the outer polygonal body, to a second position, in which a majority of the inner polygonal body is disposed within the outer polygonal body. When the inner polygonal body is moved from the first position to the second position after the arms are inserted through the hole in the component, the arms deform radially outward such that a portion of the component surrounding the hole is captured between an annular flange on the outer polygonal body and the arms.

Description

Attorney Docket No.0275-001776-WO-POA REUSABLE NUT CONFIGURED TO BE FIXED WITHIN HOLE IN COMPONENT AND TO BECOME PART OF ASSEMBLY WITH THE COMPONENT CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a PCT International Application which claims the benefit of U.S. Provisional Application No. 63 / 527,270, filed on July 17, 2023. The entire disclosure of the above application is incorporated herein by reference. FIELD

[0002] The present disclosure relates to a reusable nut configured to be fixed within a hole in a component and to become part of assembly with the component. BACKGROUND

[0003] The background description provided here is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

[0004] A reusable nut is secured within a hole in the mating component so that a threaded stud attached to another component may be threaded into the nut to secure the other component to the mating component. To disassemble the other component from the mating component, the nut is rotated, which causes the threaded stud to back out of the nut. The nut may then be reused to secure a different component to the mating component by inserting a stud attached to the different component into the nut.

[0005] A reusable nut may be formed as two pieces or a single piece. A two-piece nut has one part that receives the threaded stud and another part, and the two parts are positioned on opposite sides of the hole in the mating component and secured to one another. In a one-piece nut, these two parts are formed together as a single body. A two-piece nut is shipped separately from the mating component. A one-piece nut may be part-of-assembly with the mating component, and the assembly may be shipped as one part, which may be a benefit to the entity receiving the mating component.Attorney Docket No.0275-001776-WO-POA SUMMARY

[0006] A reusable nut according to the present disclosure is configured to be secured within a hole in a component. In one example, the nut includes an inner polygonal body, an outer polygonal body, and a pair of arms connecting the inner and outer polygonal bodies to one another. The arms allow the inner polygonal body to move relative to the outer polygonal body from a first position, in which a majority of the inner polygonal body is disposed outside of the outer polygonal body, to a second position, in which a majority of the inner polygonal body is disposed within the outer polygonal body. When the inner polygonal body is moved from the first position to the second position after the arms are inserted through the hole in the component, the arms deform radially outward such that a portion of the component surrounding the hole is captured between an annular flange on the outer polygonal body and the arms.

[0007] In one aspect, the entire nut is formed as a single piece.

[0008] In one aspect, one end of each arm is attached to the lower end of the outer polygonal body, and the other end of each arm is attached to the outer surface of the inner polygonal body.

[0009] In one aspect, the nut further includes stud guides projecting radially inward from the inner surface of the inner polygonal body. When the stud is inserted into the central aperture in the inner polygonal body, the stud guides engage the stud and thereby coaxially align the stud with the inner polygonal body.

[0010] In one aspect, the perimeters of the inner and outer polygonal bodies have a non-circular shape.

[0011] In one aspect, the inner polygonal body includes locking tabs that engage locking apertures in the outer polygonal body, and thereby lock the inner polygonal body within the outer polygonal body, when the inner polygonal body is in the second position.

[0012] In one aspect, the inner polygonal body has windows extending through the inner and outer surfaces thereof, and the locking tabs are disposed within the windows.

[0013] In one aspect, the locking tabs on the inner polygonal body flex radially inward as the inner polygonal body initially moves into the outer polygonal body, and the locking tabs return to their relaxed state when ramped protrusions thereon are aligned with and extend into the locking apertures in the outer polygonal body.Attorney Docket No.0275-001776-WO-POA

[0014] In one aspect, the locking tabs and the stud engagement tabs are connected to the rest of the inner polygonal body independent of one another.

[0015] In one aspect, each arm includes a lever connected between a first reduced thickness section and a second reduced thickness section.

[0016] In one aspect, as the nut is inserted into the hole in the component, the perimeter of the hole engages the lever and thereby causes the lever to pivot about the first and second reduced thickness sections toward the inner polygonal body. When the lever is inserted completely through the hole, the lever pivots in the opposite direction and engages an underside surface of the component to inhibit withdrawal of the nut from the hole.

[0017] In one aspect, as the inner polygonal body is moved from the first position to the second position while the nut is inserted into the hole in the component, an underside surface of the component engages one end of the lever and thereby causes the lever to pivot about the first and second reduced thickness sections. As the lever pivots, the arms pull the outer polygonal body into the hole in the component while pushing the inner polygonal body into the outer polygonal body.

[0018] In one aspect, the lever pivots to an orientation generally parallel to a longitudinal axis of the nut as the nut is inserted into the hole in the component, and the lever pivots to an orientation generally perpendicular to the longitudinal axis of the nut as the inner polygonal body is moved from the first position to the second position.

[0019] In one aspect, the inner polygonal body includes a pair of flanges projecting in opposite directions from the outer surface of the inner polygonal body and ramped protrusions disposed on the flanges. When the inner polygonal body is moved from the first position to the second position, the ramped protrusions engage an inner surface of the outer polygonal body at the lower end thereof and thereby coaxially align the inner and outer polygonal bodies with one another.

[0020] In another example, the nut includes an inner body, an outer body, and a pair of arms. The inner body has an inner surface and an outer surface. The inner surface defines a central aperture configured to receive a stud. The inner surface has stud engagement tabs projecting inward therefrom for engaging threads on the stud. The inner body and the stud engagement tabs are part of a one-piece structure. The outer body has an upper end, a lower end, and a flange projecting outward from the lower end of the outer body. The arms connect the inner and outer bodies to one anotherAttorney Docket No.0275-001776-WO-POA while allowing the inner body to move relative to the outer body from a first position, in which a majority of the inner body is disposed outside of the outer body, to a second position, in which a majority of the inner body is disposed within the outer body. The inner body and the arms are insertable into the hole in the component when the inner body is in the first position. When the inner body is moved from the first position to the second position after the arms are inserted through the hole in the component, the arms deform outward such that a portion of the component surrounding the hole is captured between the flange on the outer body and the arms.

[0021] In one aspect, the outer body and the arms are also part of the one-piece structure.

[0022] In one aspect, the inner and outer bodies are shaped to transfer load from the outer body to the inner body when the outer body is rotated.

[0023] In one aspect, when the inner body is in the second position and the stud is inserted into the central aperture of the inner body, the outer body is rotatable to cause the inner body to rotate, which unthreads the stud from the stud engagement tabs and thereby removes the stud from the nut.

[0024] In one aspect, the inner body includes locking tabs that engage locking apertures in the outer body and thereby lock the inner body within the outer body when the inner body is in the second position.

[0025] In one aspect, the locking tabs are connected to the rest of the inner body independent of the stud engagement tabs, and the stud engagement tabs are connected to the rest of the inner body independent of the locking tabs.

The detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Referring now to FIGS.1 and 2, a nut 10 is assembled to a mating component 12, such as a flange or bracket, and is part of assembly (POA) with the mating component 12 for ease of installation into a final product such as a vehicle. The nut 10 is secured within a hole 14 in the mating component 12. The nut 10 is configured to receive a bolt or stud 16, such as a T5, T6, or M6 bolt or stud, and to engage threads 18 thereof. The stud 16 may be POA with another component, such as a piece of sheet metal, so that the nut 10 and the stud 16 join the other component to the mating component 12.Attorney Docket No.0275-001776-WO-POA

[0043] With additional reference to FIGS. 3 through 13, the nut 10 is formed (e.g., injection molded) from plastic (e.g., nylon) as a single piece. The nut 10 includes an inner polygonal body 20, an outer polygonal body 22, and a pair of arms 24 connecting the inner and outer polygonal bodies 20 and 22 to one another. The inner polygonal body 20 has an upper end 26, a lower end 28, an inner surface 30, and an outer surface 32. A pair of arc-shaped flanges 34 project in opposite directions from the outer surface 32, and a plurality of ramped protrusions 36 are disposed on the flanges 34. Three stud guides 38 project radially inward from the inner surface 30, and three stud engagement tabs 40 project upward and radially inward from the inner surface 30. A pair of openings or windows 42 extend through the inner and outer surfaces 30 and 32, and a pair of locking tabs 44 extend downward into the windows 42. Each locking tab 44 has a ramped protrusion 45 that projects radially outward therefrom.

[0044] The outer polygonal body 22 has an upper end 46, a lower end 48, and an annular flange 50 projecting radially outward from the lower end 48. A pair of locking apertures 52 extend radially through the outer polygonal body 22 adjacent to the lower end 48. One end of each arm 24 is attached to the lower end 48 of the outer polygonal body 22, and the other end of each arm 24 is attached to the outer surface 32 of the inner polygonal body 20 adjacent to the lower end 28 thereof. Each arm 24 includes a lever 54 connected between a first reduced thickness section 56 and a second reduced thickness section 58.

[0045] FIGS. 3 through 10 show the nut 10 before the nut 10 is assembled to the mating component 12. In this state, a majority (e.g., all) of the inner polygonal body 20 is disposed outside of the outer polygonal body 22, and the outermost diameter of the arms 24 is less than the diameter of the annular flange 50. FIGS. 14 through 19 illustrate assembly of the nut 10 to the mating component 12. FIGS.14 through 19 are sectioned perspective views of the nut 10 and the mating component 12, as portions of the nut 10 and the mating component 12 have been omitted for illustration purposes.

[0046] In FIGS.14 through 16, a tool 60 is used to push the nut 10 downward into the hole 14 in the mating component 12. As the nut 10 is inserted into the hole 14, the perimeter of the hole 14 engages the lever 54 of each arm 24. In turn, each lever 54 pivots about the first and second reduced thickness sections 56 and 58 to a generally vertical orientation (e.g., generally parallel to a longitudinal axis A-A of the nut 10) and moves radially inward toward the inner polygonal body 20. When the levers 54 areAttorney Docket No.0275-001776-WO-POA inserted completely through the hole 14, the levers 54 moves radially outward and return to their relaxed state.

[0047] Notably, when the levers 54 is inserted completely through the hole 14, the nut 10 is temporarily secured to the mating component 12 since the nut 10 cannot be pulled out of the hole 14 due to engagement between the upper ends of the levers 54 and the mating component 12. This feature provides more flexibility in the assembly process. For example, the nut 10 may be temporarily set to the mating component 12 in one station, and then permanently secured to the mating component 12 in another station.

[0048] In FIGS.17 through 19, a tool 62 is used to push the inner polygonal body 20 upward into the outer polygonal body 22 and thereby permanently secure the nut 10 within the hole 14 in the mating component 12. Although not shown, another tool or object may be positioned above the nut 10 so that the nut 10 is compressed between the tool 62 and the other object or tool. As the inner polygonal body 20 is pushed upward, an underside surface 64 of the mating component 12 engages one end of each lever 54 and thereby causes the lever 54 to pivot about the first and second reduced thickness sections 56 and 58 to a generally horizontal orientation (e.g., generally perpendicular to the longitudinal axis A-A of the nut 10). In turn, the portion of the mating component 12 surrounding the hole 14 is captured between the annular flange 50 of the outer polygonal body 22 and the arms 24 as shown in FIGS. 2 and 12, thereby securing the nut 10 to the mating component 12. As the lever 54 pivots, the arms 24 pull the outer polygonal body 22 downward to the hole 14 in the mating component 12 while pushing the inner polygonal body 20 upward into the outer polygonal body 22. The ramped protrusions 36 on the inner polygonal body 20 engage an inner surface 66 of the outer polygonal body 22 at the lower end 48 thereof and thereby coaxially align the inner and outer polygonal bodies 20 and 22.

[0049] The locking tabs 44 on the inner polygonal body 20 flex radially inward as the inner polygonal body 20 initially moves into the outer polygonal body 22. The locking tabs 44 return to their relaxed state when the ramped protrusions 45 thereon are aligned with and extend into the locking apertures 52 in the outer polygonal body 22. The engagement between the locking tabs 44 and the locking apertures 52 inhibits the inner polygonal body 20 from moving back out of the outer polygonal body 22.

[0050] Once the nut 10 is secured within the hole 14 in the mating component 12 as shown in FIG.12, the stud 16 may be inserted into the nut 10 by positioning a centralAttorney Docket No.0275-001776-WO-POA aperture 68 in the inner polygonal body 20 over the stud 16 and moving the mating component 12 toward the stud 16 so that the central aperture 68 receives the stud 16. As the stud 16 moves into the inner polygonal body 20, the stud guides 38 on the inner polygonal body 20 engage the stud 16 and thereby coaxially align the stud 16 with the inner polygonal body 20. This may be particularly beneficial during blind assembly of the other component with the stud 16 to the mating component 12 with the nut 10, when the insertion of the stud 16 into the central aperture 68 in the nut 10 is not visible to the assembler. In addition, the stud engagement tabs 40 on the inner polygonal body 20 engage the threads 18 on the stud 16 and thereby inhibit withdrawal of the stud 16. While this engagement is not shown in FIG. 2 due to the location of the section cut used to generate FIG.2, this engagement is shown in FIG.13.

[0051] The stud 16 may be removed from the nut 10 and the nut 10 may be reused with the stud 16 (or another stud) to attach another component to the mating component 12, which improves the serviceability of the assembly. To remove the stud 16 from the nut 10, a tool (e.g., a socket) is placed on the outer polygonal body 22 and rotated. Since the perimeters of the inner and outer polygonal bodies 20 and 22 are both polygonal (e.g., a closed plane figure bounded by straight lines), the inner polygonal body 20 rotates with the outer polygonal body 22 without subjecting the arms 24 to high stress. Rotation of the inner polygonal body 20 in a certain direction (e.g., counterclockwise) causes the stud 16 to unthread from the stud engagement tabs 40 and thereby moves the stud 16 downward out of the inner polygonal body 20. In the example shown, the perimeters of the inner and outer polygonal bodies 20 and 22 are both hexagonal. In various implementations, the perimeters of the inner and outer bodies 20 and 22 may have a non-circular shape other than hexagonal, such as square, pentagonal, or octagonal. In addition, the perimeters of the inner and outer bodies 20 and 22 may have the same non-circular shape or different non-circular shapes.

[0052] The inner and outer polygonal bodies 20 and 22 are shaped to transfer load from the outer polygonal body 22 to the inner polygonal body 20 when the outer polygonal body 22 is rotated, which ensures that the nut 10 does not fail when rotated to back out the stud 16 such that nut 10 is reusable. In contrast, some nuts or clips do not have inner and outer bodies that are shaped to transfer load from the outer body to the inner body. For example, KR102361302B1 describes a clip including an outer body and two elongated inner bodies that are not shaped to transfer load from the outer bodyAttorney Docket No.0275-001776-WO-POA to the inner bodies when the outer body is rotated. Thus, all of the load is transferred through legs that connect the inner and outer bodies to one another. As a result, the legs may fail when rotating the outer body to back a stud out of the clip, and therefore the clip may not be reusable.

[0053] The locking tabs 44, which lock the inner polygonal body 20 within the outer polygonal body 22, and the stud engagement tabs 40 are independently connected to the inner polygonal body 20 (a rigid body) and therefore flex independently of one another. In turn, when the stud 16 is subjected to an extraction force, any flexure of the stud engagement tabs 40 does not cause the locking tabs 44 to flex. Thus, the stud engagement tabs 40 fail before the locking tabs 44 disengaged from the locking apertures 52 in the outer polygonal body 22. As a result, the nut 10 can withstand high extraction forces applied to the stud 16.

[0054] In contrast, in some nuts or clips, the locking features and the stud engagement features are on the same flexible body. For example, KR102361302B1 describes a clip including two flexible inner bodies that each have a locking feature locking the flexible inner bodies to an outer body and a stud engagement feature that engages a stud. Thus, when an extraction force is applied to the stud, any flexure of the stud engagement features may also cause the locking features to flex. In turn, the locking features may disengage from the outer body before the stud engagement features fail. As a result, the clip cannot withstand as high as stud extraction forces as the nut 10.

[0055] The foregoing description is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. The broad teachings of the disclosure can be implemented in a variety of forms. Therefore, while this disclosure includes particular examples, the true scope of the disclosure should not be so limited since other modifications will become apparent upon a study of the drawings, the specification, and the following claims. It should be understood that one or more steps within a method may be executed in different order (or concurrently) without altering the principles of the present disclosure.
