A reusable nut configured to be fixed within a hole in a component and to form an assembly part with that component.

Abstract

A nut is configured to be fixed within a hole in the 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 each other. The arms allow the inner polygonal body to move relative to the outer polygonal body from a first position in which most of the inner polygonal body is located outside the outer polygonal body to a second position in which most of the inner polygonal body is located inside the outer polygonal body. When the inner polygonal body is moved from the first position to the second position after the arms have been inserted through the hole in the component, the arms deform radially outward so that a portion of the component surrounding the hole is captured between the annular flange on the outer polygonal body and the arms.

[0001] Cross - Reference to Related Applications This application is a PCT international application claiming 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.

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

Background Art

[0003] The description of the background art provided herein is for the purpose of generally presenting the background of the present disclosure. The research within the scope described in this background art section by the inventors named currently, as well as aspects of this description that may not be considered prior art in other forms at the time of filing, are not admitted as prior art to the present disclosure, either explicitly or implicitly.

[0004] When a reusable nut is fixed within a hole of a mating component, it thereby enables a threaded stud attached to another component to be screwed into the nut to fix the other component to the mating component. To remove the other component from the mating component, the nut is rotated, thereby causing the threaded stud to retreat and come out of the nut. Then, the nut can be reused to insert the stud attached to a different component into the nut to fix the different component to the mating component.

[0005] Reusable nuts can be formed as two-piece or single-piece nuts. A two-piece nut has one part that receives a threaded stud and another part, and these two parts are positioned on opposite sides of the hole in the mating component and are fastened together. In a one-piece nut, these two parts are formed together as a single body. Two-piece nuts are shipped separately from the mating component. A one-piece nut can be assembled with the mating component, and this assembly can be shipped as a single part, which may be beneficial to the entity receiving the mating component. [Overview of the project]

[0006] The reusable nuts provided in this disclosure are configured to be fixed into 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 each other. The arms allow the inner polygonal body to move relative to the outer polygonal body from a first position in which the majority of the inner polygonal body is located outside the outer polygonal body to a second position in which the majority of the inner polygonal body is located inside the outer polygonal body. When the inner polygonal body is moved from the first position to the second position after the arms have been inserted through the hole in the component, the arms deform radially outward so that a portion of the component surrounding the hole is captured between the annular flange on the outer polygonal body and the arms.

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

[0008] In one embodiment, 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 embodiment, the nut further includes a stud guide projecting radially inward from the inner surface of the inner polygonal body. When the stud is inserted into the central opening of the inner polygonal body, the stud guide engages with the stud, thereby aligning the stud coaxially with the inner polygonal body.

[0010] In one embodiment, the outer periphery of the inner polygonal body and the outer polygonal body has a non-circular shape.

[0011] In one embodiment, the inner polygonal body includes a locking tab that engages with a locking opening of the outer polygonal body when the inner polygonal body is in a second position, thereby locking the inner polygonal body within the outer polygonal body.

[0012] In one embodiment, the inner polygonal body has windows that penetrate its inner and outer surfaces, and locking tabs are disposed within these windows.

[0013] In one embodiment, the locking tab on the inner polygonal body bends radially inward when the inner polygonal body first moves into the outer polygonal body, and the locking tab returns to a relaxed state when the inclined projection on the locking tab aligns with the locking opening of the outer polygonal body and protrudes into the locking opening.

[0014] In one embodiment, the locking tab and the stud engaging tab are connected independently to the rest of the inner polygonal body.

[0015] In one embodiment, each arm includes a lever connected between a first thinning section and a second thinning section.

[0016] In one embodiment, when the nut is inserted into the hole of the component, the periphery of the hole engages with the lever, thereby causing the lever to pivot toward the inner polygonal body around the first and second thinning sections. When the lever is fully inserted through the hole, the lever pivots in the opposite direction and engages with the lower surface of the component, preventing the nut from being removed from the hole.

[0017] In one embodiment, as the inner polygonal body is moved from a first position to a second position while the nut is inserted into the hole of the component, the lower surface of the component engages with one end of the lever, thereby causing the lever to pivot around the first and second thinning sections. As the lever pivots, the arm pulls the outer polygonal body into the hole of the component and pushes the inner polygonal body into the outer polygonal body.

[0018] In one embodiment, when the nut is inserted into the hole of the component, the lever rotates in a direction generally parallel to the longitudinal axis of the nut, and when the inner polygonal body is moved from a first position to a second position, the lever rotates in a direction generally perpendicular to the longitudinal axis of the nut.

[0019] In one embodiment, the inner polygonal body includes a pair of flanges projecting in opposite directions from the outer surface of the inner polygonal body, and an inclined projection disposed on the flanges. When the inner polygonal body is moved from a first position to a second position, the inclined projection engages with the inner surface of the outer polygonal body at the lower end of the outer polygonal body, thereby aligning the inner and outer polygonal bodies coaxially.

[0020] In another example, a nut includes an inner body, an outer body, and a pair of arms. The inner body has an inner and an outer surface. The inner surface defines a central opening configured to receive a stud. The inner surface has a stud engaging tab projecting inward from the inner surface for engaging with the threads on the stud. The inner body and the stud engaging tab are part of a one-piece structure. The outer body has an upper end, a lower end, and flanges projecting outward from the lower end of the outer body. The arms connect the inner and outer bodies to each other and allow the inner body to move relative to the outer body from a first position where most of the inner body is located outside the outer body to a second position where most of the inner body is located inside the outer body. The inner body and arms are insertable into a 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 have been inserted through the hole in the component, the arms deform outward so that a portion of the component surrounding the hole is captured between the flange on the outer body and the arms.

[0021] In one embodiment, the outer body and arm are part of a single-piece structure.

[0022] In one embodiment, the inner body and the outer body are shaped to transmit a load from the outer body to the inner body when the outer body is rotated.

[0023] In one embodiment, when the inner body is in a second position and the stud is inserted into the central opening of the inner body, the outer body is rotatable so as to rotate the inner body, thereby unthreading the stud from the stud engagement tab and thereby removing the stud from the nut.

[0024] In one embodiment, the inner body includes a locking tab that engages with a locking opening of the outer body when the inner body is in a second position, thereby locking the inner body into the outer body.

[0025] In one aspect, the locking tab is connected to the remainder of the inner body independently of the stud engaging tab, and the stud engaging tab is connected to the remainder of the inner body independently of the locking tab.

[0026] Further scope of the present disclosure will become apparent from the embodiments, claims, and drawings for carrying out the invention. The embodiments and specific examples are merely intended for illustration purposes and are not intended to limit the scope of the present disclosure.

[0027] The present disclosure will become more fully understood from the embodiments for carrying out the invention and the accompanying drawings.

[Figure 14-19]This is a cross-sectional perspective view of the nut shown in Figure 1, which is inserted into a hole in the mating component shown in Figure 1 and fixed within the hole. [Modes for carrying out the invention]

[0029] In drawings, reference numbers may be reused to identify similar and / or identical elements.

[0030] Referring to Figures 1 and 2, the nut 10 is assembled to a mating component 12, such as a flange or bracket, and the nut 10 forms a point of assembly (POA) with the mating component 12 to facilitate assembly into a final product such as a vehicle. The nut 10 is fixed in a hole 14 of 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 with its threads 18. The stud 16 forms a POA with another component, such as a thin metal sheet, thereby allowing the nut 10 and stud 16 to join the other component to the mating component 12.

[0031] Referring further to Figures 3 to 13, the nut 10 is formed as a single piece from plastic (e.g., nylon) (e.g., by injection molding). The nut 10 includes an inner polygonal body 20, an outer polygonal body 22, and a pair of arms 24 connecting the inner polygonal body 20 and the outer polygonal body 22 to each other. 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 arcuate flanges 34 project in opposite directions from the outer surface 32, and a plurality of inclined projections 36 are disposed on the flanges 34. Three stud guides 38 project radially inward from the inner surface 30, and three stud engaging tabs 40 project upward and radially inward from the inner surface 30. A pair of openings or windows 42 penetrate the inner surface 30 and the outer surface 32, and a pair of locking tabs 44 project downward into the windows 42. Each locking tab 44 has an inclined projection 45 that protrudes radially outward from it.

[0032] 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 openings 52 penetrate the outer polygonal body 22 radially 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 of the inner polygonal body 20. Each arm 24 includes a lever 54 connected between the first thinning section 56 and the second thinning section 58.

[0033] Figures 3 to 10 show the nut 10 before it is assembled to the mating component 12. In this state, most (for example, all) of the inner polygonal body 20 is located outside the outer polygonal body 22, and the outermost diameter of the arm 24 is less than the diameter of the annular flange 50. Figures 14 to 19 show the assembly of the nut 10 to the mating component 12. Figures 14 to 19 are cross-sectional perspective views of the nut 10 and the mating component 12, with some parts of the nut 10 and the mating component 12 omitted for illustrative purposes.

[0034] In Figures 14 to 16, the tool 60 is used to push the nut 10 downward into the hole 14 of the mating component 12. As the nut 10 is inserted into the hole 14, the periphery of the hole 14 engages with the lever 54 of each arm 24. As a result, each lever 54 pivots generally perpendicular (for example, generally parallel to the longitudinal axis AA of the nut 10) around the first thinning section 56 and the second thinning section 58, and moves radially inward toward the inner polygonal body 20. When the lever 54 is fully inserted through the hole 14, the lever 54 moves radially outward, returning to its relaxed state.

[0035] In particular, when the lever 54 is fully inserted through the hole 14, the nut 10 is temporarily fixed to the mating component 12 because the engagement between the upper end of the lever 54 and the mating component 12 prevents the nut 10 from being pulled out of the hole 14. This feature provides greater flexibility in the assembly process. For example, the nut 10 can be temporarily set on the mating component 12 at one station and then permanently fixed to the mating component 12 at another station.

[0036] In Figures 17-19, a tool 62 is used to push the inner polygonal body 20 upward into the outer polygonal body 22, thereby permanently securing the nut 10 in the hole 14 of the mating component 12. Although not shown, another tool or object may be placed on 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, the lower surface 64 of the mating component 12 engages with one end of each lever 54, thereby rotating the lever 54 in a generally horizontal orientation (for example, generally perpendicular to the longitudinal axis AA of the nut 10) around the first thinning section 56 and the second thinning section 58. As a result, a portion of the mating component 12 surrounding the hole 14 is captured between the annular flange 50 and the arm 24 of the outer polygonal body 22, as shown in Figures 2 and 12, thereby securing the nut 10 to the mating component 12. When the lever 54 rotates, the arm 24 pulls the outer polygonal body 22 downwards into the hole 14 of the mating component 12, and pushes the inner polygonal body 20 upwards into the outer polygonal body 22. The inclined projection 36 on the inner polygonal body 20 engages with the inner surface 66 of the outer polygonal body 22 at the lower end 48 of the outer polygonal body 22, thereby aligning the inner polygonal body 20 and the outer polygonal body 22 coaxially.

[0037] The locking tab 44 on the inner polygonal body 20 bends radially inward when the inner polygonal body 20 first moves into the outer polygonal body 22. The locking tab 44 returns to its relaxed state when the inclined projection 45 on the locking tab 44 aligns with the locking opening 52 of the outer polygonal body 22 and protrudes into the locking opening 52. The engagement between the locking tab 44 and the locking opening 52 prevents the inner polygonal body 20 from retracting out of the outer polygonal body 22.

[0038] As shown in Figure 12, after the nut 10 is fixed in the hole 14 of the mating component 12, the stud 16 can be inserted into the nut 10 by positioning the central opening 68 of the inner polygonal body 20 to cover the stud 16, bringing the mating component 12 closer to the stud 16, thereby allowing the central opening 68 to receive the stud 16. When the stud 16 is moved into the inner polygonal body 20, the stud guide 38 on the inner polygonal body 20 engages with the stud 16, thereby aligning the stud 16 coaxially with the inner polygonal body 20. This can be particularly beneficial during blind assembly of another component with a stud 16 into the mating component 12 with a nut 10, when the insertion of the stud 16 into the central opening 68 of the nut 10 is not visible to the assembler. In addition, the stud engaging tab 40 on the inner polygonal body 20 engages with the threads 18 on the stud 16, thereby preventing the stud 16 from being pulled out. Due to the location of the cross-sectional cut used to generate Figure 2, this engagement is not shown in Figure 2, but it is shown in Figure 13.

[0039] The stud 16 can be removed from the nut 10, and the nut 10 can be reused with the stud 16 (or another stud) to attach another component to the mating component 12, thereby improving the utility 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 outer peripheries of both the inner polygonal body 20 and the outer polygonal body 22 are polygons (e.g., closed planar figures enclosed by straight lines), the inner polygonal body 20 rotates together with the outer polygonal body 22 without exposing the arm 24 to great stress. When the inner polygonal body 20 rotates in a particular direction (e.g., counterclockwise), the stud 16 disengages from the stud engagement tab 40, thereby moving the stud 16 downwards outward from the inner polygonal body 20. In the illustrated example, the outer peripheries of both the inner polygonal body 20 and the outer polygonal body 22 are hexagonal. In various implementation configurations, the outer periphery of the inner body 20 and the outer body 22 can have non-circular shapes other than hexagons, such as squares, pentagons, or octagons. In addition, the outer periphery of the inner body 20 and the outer body 22 can have the same non-circular shape, or they can have different non-circular shapes.

[0040] The inner polygonal body 20 and the outer polygonal body 22 are shaped to transmit the load from the outer polygonal body 22 to the inner polygonal body 20 when the outer polygonal body 22 is rotated, thereby ensuring that the nut 10 does not fail when the nut 10 is rotated to retract the stud 16, and therefore the nut 10 is reusable. In contrast, some nuts or clips do not have an inner and outer body shaped to transmit the load from the outer body to the inner body. For example, KR102361302B1 describes a clip that includes an outer body and two elongated inner bodies that are not shaped to transmit the load from the outer body to the inner body when the outer body is rotated. Therefore, all the load is transmitted through the legs that connect the inner and outer bodies to each other. As a result, the legs may fail when the outer body is rotated to retract the stud out of the clip, and therefore the clip may not be reusable.

[0041] The locking tab 44 and stud engaging tab 40, which lock the inner polygonal body 20 into the outer polygonal body 22, are independently connected to the inner polygonal body 20 (rigid body) and therefore bend independently of each other. As a result, when the stud 16 is subjected to an extraction force, the locking tab 44 does not bend even if the stud engaging tab 40 bends. Therefore, the stud engaging tab 40 fails before the locking tab 44 is disengaged from the locking opening 52 of the outer polygonal body 22. Consequently, the nut 10 can withstand the large extraction force applied to the stud 16.

[0042] In contrast, in some nuts or clips, the locking feature and the stud engaging feature are located on the same flexible body. For example, KR102361302B1 describes a clip comprising two flexible inner bodies, each having a locking feature for locking the flexible inner body to an outer body and a stud engaging feature for engaging with a stud. Therefore, when a pull-out force is applied to the stud, if the stud engaging feature bends, the locking feature may also bend. As a result, the locking feature may disengage from the outer body before the stud engaging feature fails. Consequently, this clip cannot withstand a stud pull-out force of the same magnitude as that of a nut 10.
