Summary of the Invention

Problems to be Solved by the Invention

[0004] The stud fitting is slidable with respect to the fixing rail. For this reason, each part dimension of the part of the stud fitting inserted into the fixing rail is such that a gap is generated between the part and the fixing rail.

[0005] For this reason, when vibration is input to the stud fitting in a state where the stud fitting is attached to the fixing rail, the stud fitting vibrates with respect to the fixing rail, so that abnormal noise accompanied by a periodic collision sound is generated.

[0006] In view of the above, this disclosure provides an example of a stud fitting that can suppress the generation of abnormal noise in a stud fitting that is detachably used on a fixed rail such as an airline rail (registered trademark). [Means for solving the problem]

[0007] The stud fitting used in the fixing rail (1) preferably has the following constituent requirements, for example. The fixing rail (1) has an opening (2) extending in the longitudinal direction, and the cross-sectional shape perpendicular to the longitudinal direction is formed in a substantially C shape, with a wide section (3) with a large opening width and a narrow section (4) with an opening width smaller than the wide section (3) alternately provided in the opening (2).

[0008] In other words, the constituent element is a first locking portion (11A~11C) of a size that can pass through the wide portion (3) and be inserted into the fixing rail (1), but cannot pass through the narrow portion (4), the first locking portion (11A~11C) being displaceable in the longitudinal direction within the fixing rail (1) when inserted into the fixing rail (1), and a second locking portion (12A~12D) being displaceable relative to the first locking portion (11A~11C), and being able to fit into the wide portion (3). The second locking portion (12A~12D) is sized to be able to fit into the narrow portion (4), and the clamping portion (12E) is displaceable relative to the first locking portion (11A~11C), and is provided on the opposite side of the first locking portion (11A~11C) with the second locking portion (12A~12D) in between, and when the second locking portion (12A~12D) is fitted into the wide portion (3), the clamping portion (12E) cooperates with the first locking portion (11A~11C) to clamp the narrow portion (4).

[0009] As a result, in this stud fitting, when the second locking portion (12A~12D) is fitted into the wide portion (3), the narrow portion (4) is sandwiched between the first locking portion (11A~11C) and the clamping portion (12E). Therefore, even if vibration is input to the stud fitting, vibration of the stud fitting relative to the fixing rail is suppressed, and thus the generation of abnormal noise can be suppressed.

Mode for carrying out the invention

[0012] The following "Embodiment of the Invention" shows an example of an embodiment belonging to the technical scope of the present disclosure. That is, the invention specific matters etc. described in the claims are not limited to the specific configurations, structures, etc. shown in the following embodiments.

[0013] This embodiment is an example in which the stud fitting according to the present disclosure is applied to an attachment used for a fixing rail mounted on a vehicle such as a car. The fixing rail is, for example, an airline rail (registered trademark) as shown in FIG. 1.

[0014] Specifically, the fixing rail 1 has an opening 2 extending in the longitudinal direction, and is a long member having a substantially C-shaped cross-sectional shape orthogonal to the longitudinal direction. In the opening 2, a wide portion 3 and a narrow portion 4 are alternately provided along the extending direction of the opening 2.

[0015] The opening width W2 of the narrow portion 4 is smaller than the opening width W1 of the wide portion 3. The wide portion 3 is configured in a round hole shape. Therefore, the opening width W2 has the maximum dimension at the intermediate portion with the adjacent narrow portion 4. The opening width W2 of the narrow portion 4 is the same dimension along the extending direction of the opening 2.

[0016] In addition, the arrows, slashes, etc. indicating the directions attached to the following respective figures are described for the purpose of facilitating the understanding of the relationship between the respective figures and the shape etc. of the member or part. Therefore, the stud fitting is not limited to the directions attached to the respective figures.

[0017] At least one of the components or parts described with reference numerals is provided, unless otherwise specified, such as "one". The stud fittings shown in this disclosure comprise at least one of the components, such as the components or parts described with reference numerals, and at least one of the illustrated structural parts.

[0018] (First Embodiment) <1. Overview of Stud Fitting> As shown in Figure 2, the stud fitting 10 is used by being attached to the fixing rail 1. In this embodiment, the stud fitting 10 is used to detachably fix the member 5 to a vehicle or the like, as shown in Figure 3.

[0019] The fixing rail 1 is directly or indirectly fixed to the vehicle body (not shown). In Figure 3, a hexahedron-shaped object is depicted as component 5, but component 5 can be any object that is mounted on the vehicle.

[0020] <1.2 Stud Fitting Configuration> As shown in Figure 4, the stud fitting 10 includes at least a first locking plate 11, a second locking plate 12, and a wire portion 13, etc.

[0021] <First locking plate> The first locking plate 11 has a plurality of first locking portions 11A to 11C, and is a strip-shaped member in which these first locking portions 11A to 11C are arranged in series and integrated. The direction in which the first locking portions 11A to 11C are arranged coincides with the direction of extension of the opening 2 when the stud fitting 10 is attached to the fixing rail 1.

[0022] Each of the first locking portions 11A to 11C is a roughly disc-shaped portion that is large enough to pass through the wide portion 3 and be inserted into the fixing rail 1, but is not large enough to pass through the narrow portion 4. Furthermore, each of the first locking portions 11A to 11C can slide and displace longitudinally within the fixing rail 1 when inserted into the fixing rail 1 (see Figure 5).

[0023] The first locking plate 11 is a single piece integrally molded with each of the first locking parts 11A to 11C from metal or resin. In this embodiment, the first locking plate 11 is made of a ferromagnetic metal such as an iron-based metal.

[0024] <Second locking plate> As shown in Figure 6, the second locking plate 12 has a plurality of second locking portions 12A to 12D and a clamping portion 12E, and is a strip-shaped member in which the second locking portions 12A to 12D are arranged in series and integrated with the clamping portion 12E.

[0025] The alignment direction of the second locking parts 12A to 12D is parallel to the alignment direction of the first locking parts 11A to 11C. Furthermore, each of the second locking parts 12A to 12D is offset from each of the first locking parts 11A to 11C in the alignment direction, that is, in the longitudinal direction of the fixing rail 1 (see Figure 7).

[0026] The amount of misalignment between each second locking portion 12A to 12D and each first locking portion 11A to 11C in the alignment direction is equal to the amount of misalignment between the wide portion 3 and the narrow portion 4 in the longitudinal direction. Specifically, for example, if the positions of each second locking portion 12A to 12D coincide with the positions of the wide portion 3, then the positions of each first locking portion 11A to 11C coincide with the positions of the narrow portion 4.

[0027] The clamping portion 12E is a canopy-like or flange-like portion that extends from each of the second locking portions 12A to 12D, as shown in Figure 5. The width dimension W3 of the clamping portion 12E (see Figure 4) is greater than the opening width W1 of the wide portion 3.

[0028] Therefore, as shown in Figure 2, the clamping portion 12E (in this embodiment, the second locking plate 12) functions as a cover that covers the wide portion 3 and the narrow portion 4, that is, a part of the opening 2, from the outside of the fixing rail 1.

[0029] As shown in Figure 5, the clamping portion 12E is provided on the opposite side of the first locking portions 11A to 11C, sandwiching the second locking portions 12A to 12D. Therefore, when the second locking portions 12A to 12D are fitted into the wide portion 3, the clamping portion 12E works in cooperation with the first locking portions 11A to 11C to clamp the narrow portion 4.

[0030] In other words, the second locking plate 12, including the clamping portion 12E, is displaceable in the vertical direction relative to the first locking portions 11A to 11C, i.e., the first locking plate 11. The vertical direction of the paper is the direction perpendicular to the plate surface 11D of the first locking plate 11 (see Figure 4).

[0031] In other words, the first locking parts 11A to 11C, the second locking parts 12A to 12D, and the clamping part 12E are arranged in series in the order of first locking parts 11A to 11C, second locking parts 12A to 12D, and clamping part 12E, along the displacement direction of the second locking parts 12A to 12D and the clamping part 12E.

[0032] A magnet 12F is fixed to the second locking plate 12, as shown in Figure 6. The magnet 12F generates a magnetic force that presses the clamping portion 12E and the first locking portions 11A to 11C against the narrow portion 4.

[0033] In other words, the magnetic force of the magnet 12F generates an attractive force between the first locking plate 11 and the second locking plate 12, causing them to attract each other. For this reason, each of the first locking parts 11A to 11C presses against the narrow part 4 from the opposite side of the clamping part 12E (the bottom side of the paper in Figure 5), with the narrow part 4 in between.

[0034] On the other hand, the clamping portion 12E presses against the narrow portion 4 from the opposite side (the upper side of the paper in Figure 5) from each of the first locking portions 11A to 11C, sandwiching the narrow portion 4. Therefore, the narrow portion 4 is sandwiched between the first locking portions 11A to 11C and the second locking portions 12A to 12D.

[0035] In this embodiment, the second locking plate 12 is a single piece molded together with the first locking portions 11A to 11C and the clamping portion 12E from metal or resin. The magnet 12F is fixed to the first locking plate 11 with countersunk screws.

[0036] <Wire section> As shown in Figure 4, the wire section 13 has two vertical sections 13A and 13B and one horizontal bar section 13C, and is configured in a roughly U-shape or C-shape. Each of the vertical sections 13A and 13B is connected to the first locking plate 11.

[0037] Specifically, as shown in Figure 7, the rising portion 13A is connected to one longitudinal end of the first locking plate 11 (in this embodiment, the first locking portion 11A). The rising portion 13B is connected to the other longitudinal end of the first locking plate 11 (in this embodiment, the first locking portion 11C).

[0038] Each of the rising sections 13A and 13B extends through the opening 2 to the outside of the fixing rail 1 when the first locking plate 11 is inserted into the fixing rail 1 (see Figure 5). Each of the rising sections 13A and 13B is connected to the first locking plate 11 by press-fitting or welding.

[0039] The second locking plate 12 is provided with through holes 12G and 12H (see Figure 4) through which the rising portions 13A and 13B pass. The inner diameter of the through holes 12G and 12H is larger than the outer diameter of the rising portions 13A and 13B. Therefore, the second locking plate 12 can be displaced relative to the first locking plate 11.

[0040] In this embodiment, the through holes 12G and 12H are oval or elliptical through holes. Specifically, among the inner diameter dimensions of the through holes 12G and 12H, the inner diameter dimension parallel to the longitudinal direction of the second locking plate 12 is larger than the inner diameter dimension perpendicular to the longitudinal direction.

[0041] The horizontal bar portion 13C is provided on the leading end side in the extension direction of the vertical portions 13A and 13B, and protrudes in a direction intersecting (in this embodiment, perpendicular to) the vertical portions 13A and 13B, connecting the two vertical portions 13A and 13B.

[0042] Furthermore, as shown in Figure 2, the horizontal bar portion 13C faces the clamping portion 12E, that is, the second locking plate 12, across the space 13D. For this reason, the wire portion 13 is configured in a roughly U-shape or a roughly C-shape.

[0043] <1.3 Other Configurations> In addition to the first locking plate 11, the second locking plate 12, and the wire portion 13, the stud fitting 10 according to this embodiment includes wedge members 14, 15, and engaging member 16, as shown in Figure 3.

[0044] <Wedge member> As shown in Figure 8, the wedge members 14 and 15 are members that are detachably inserted into the space 13D and generate a force that separates the clamping portion 12E and the horizontal bar portion 13C when inserted into the space 13D.

[0045] In other words, tapered portions 14A and 15A are provided on the insertion-direction tip side of each wedge member 14 and 15. Each tapered portion 14A and 15A is a part where the height dimension H decreases towards the tip.

[0046] The height dimension H refers to the external dimensions of the wedge members 14 and 15 in the direction parallel to the direction from the clamping portion 12E toward the horizontal bar portion 13C. In this embodiment, the height dimension H is the dimension of the portion of each tapered portion 14A and 15A that is parallel to the extension direction of the rising portions 13A and 13B.

[0047] In this embodiment, the wedge members 14 and 15 are fixed to member 5 (see Figure 3). As shown in Figure 9, the wedge members 14 and 15 are constructed with metal frames 14B and 15B and resin covers 14C and 15C, etc.

[0048] Frames 14B and 15B are structural members that constitute the framework of the wedge members 14 and 15. The frames 14B and 15B are provided with mounting portions 14D and 15D for attaching the wedge members 14 and 15 to member 5.

[0049] Each cover 14C and 15C covers at least a portion of each frame 14B and 15B and constitutes each tapered portion 14A and 15A. Therefore, when the wedge members 14 and 15 are fitted into the space 13D, each cover 14C and 15C deforms slightly, causing the covers 14C and 15C to press against the clamping portion 12E and the horizontal bar portion 13C.

[0050] At this time, the restoring force generated by the deformation of each cover 14C and 15C becomes a force that separates the clamping portion 12E and the horizontal bar portion 13C. Therefore, the clamping portion 12E is pressed against the narrow portion 4 from the opposite side of the first locking plate 11 by this restoring force, sandwiching the narrow portion 4.

[0051] On the other hand, as the horizontal bar portion 13C moves away from the clamping portion 12E, the first locking plate 11 connected to the wire portion 13, that is, each first locking portion 11A to 11C, is pressed against the narrow portion 4 from the opposite side of the clamping portion 12E, with the narrow portion 4 in between.

[0052] <Engaging member> As shown in Figure 3, the engaging member 16 is a member indirectly connected to the wedge members 14 and 15 via member 5, and a portion of it fits into the opening 2 and engages with the fixing rail 1.

[0053] Specifically, the engaging member 16 is a lever-shaped member, as shown in Figure 10. One longitudinal end of the engaging member 16 is pivotably connected to the lower surface of member 5 via a bracket 16A.

[0054] An engaging projection 16B is provided on the other end of the engaging member 16 in the longitudinal direction, which can be fitted into the opening 2. Therefore, when the engaging projection 16B is positioned above the opening 2, the engaging member 16 swings downward due to gravity acting on it. As a result, the engaging projection 16B fits into the opening 2, and the engaging member 16 engages with the fixing rail 1.

[0055] Furthermore, a knob portion 16C is provided on the other end of the engaging member 16 in the longitudinal direction. The knob portion 16C is a part used, for example, by a user of the stud fitting 10 when displacing the engaging projection 16B that is fitted into the opening 2 upward, that is, when swinging the engaging member 16.

[0056] <3. Features of the stud fitting according to this embodiment> <3.1 Attaching stud fittings to the fixing rail> As shown in Figure 11A, before being attached to the fixing rail 1, the stud fitting 10 is in contact with the first locking plate 11 and the second locking plate 12 due to the attractive force of the magnet 12F.

[0057] Next, the user aligns each of the first locking parts 11A to 11C with the wide part 3 and inserts the first locking plate 11 into the fixing rail 1 (see Figure 11B). In this state, each of the second locking parts 12A to 12D is located in the narrow part 4, so the first locking plate 11 and the second locking plate 12 are spaced apart by an amount equivalent to the thickness h of the narrow part 4 (see Figure 1).

[0058] Next, the user slides the stud fitting 10. When each of the second locking parts 12A to 12D aligns with the wide part 3, the second locking parts 12A to 12D are fitted into the wide part 3 (see Figure 11C).

[0059] As a result, the magnetic force of the magnet 12F causes each of the first locking portions 11A to 11C to press against the narrow portion 4 from the opposite side of the clamping portion 12E, with the narrow portion 4 in between. On the other hand, the clamping portion 12E presses against the narrow portion 4 from the opposite side of the first locking portions 11A to 11C, with the narrow portion 4 in between.

[0060] Therefore, the narrow portion 4 is sandwiched between the first locking portions 11A to 11C and the clamping portion 12E. Consequently, even if vibration is input to the stud fitting 10, vibration of the stud fitting 10 relative to the fixing rail 1 is suppressed, thus suppressing the generation of abnormal noise.

[0061] As the second locking parts 12A to 12D are fitted into the wide part 3 and locked in place, the stud fitting 10 is prevented from sliding relative to the fixing rail 1. Furthermore, as the first locking parts 11A to 11C are locked into the narrow part 4, the stud fitting 10 is prevented from coming off the fixing rail 1.

[0062] <3.2 Installation of wedge members and engaging members> For example, as shown in Figures 12A to 12C, when the user moves member 5 in the order of Figure 12A → Figure 12B → Figure 12C, the wedge members 14 and 15 fit into the space 13D between the horizontal bar portion 13C and the first locking plate 11, and the engaging projection 16B fits into the opening 2.

[0063] Then, as the wedge members 14 and 15 fit into the space 13D, the clamping portion 12E is pressed against the narrow portion 4 from the side opposite to the first locking plate 11, and each of the first locking portions 11A to 11C is pressed against the narrow portion 4 from the side opposite to the clamping portion 12E, with the narrow portion 4 in between.

[0064] Therefore, since the narrow portion 4 is firmly clamped by the clamping portion 12E and each of the first locking portions 11A to 11C, even if a large vibration is input to the stud fitting 10, it is possible to reliably suppress the stud fitting 10 from vibrating relative to the fixing rail 1.

[0065] Furthermore, the engaging projection 16B fits into the opening 2, which can prevent the wedge members 14 and 15 from coming out of the space 13D via member 5. Thus, the stud fitting 10 remains engaged with the fixing rail 1.

[0066] (Second Embodiment) In the above-described embodiment, the wedge members 14 and 15 were inserted into the space 13D from a direction parallel to the plate surface 11D of the first locking plate 11 (see Figure 4). In contrast, in this embodiment, as shown in Figure 13, the wedge members 14 and 15 are inserted into the space 13D from a direction inclined with respect to the plate surface 11D of the first locking plate 11.

[0067] Therefore, the plate surface 11D of the first locking plate 11 is provided with an inclined guide portion 11E that guides the insertion of the wedge members 14 and 15. Note that components identical to those in the above-described embodiment are denoted by the same reference numerals. Therefore, redundant explanations are omitted in this embodiment.

[0068] (Third embodiment) In the above-described embodiment, the wedge members 14 and 15 were not displaced after being inserted into the space 13D. In contrast, the wedge members 14 and 15 in this embodiment are bent into a hook shape, as shown in Figure 14. Therefore, the wedge members 14 and 15 in this embodiment can rotate around the horizontal bar portion 13C even after being inserted into the space 13D.

[0069] Note that components identical to those in the above-described embodiments are denoted by the same reference numerals. Therefore, redundant explanations are omitted in this embodiment. (Fourth Embodiment) In the above-described embodiment, the second locking plate 12 had a configuration in which the clamping portion 12E and a plurality of second locking portions 12A to 12D were integrated. In contrast, in the present embodiment, as shown in Figure 15, the second locking plate 12 is composed only of the second locking portions 12A to 12D.

[0070] Then, the wedge members 14 and 15 (covers 14C and 15C in this embodiment) function as the clamping portion 12E. In other words, when the wedge members 14 and 15 are inserted into the space 13D, the covers 14C and 15C press against the narrow portion 4 from the side opposite the first locking plate 11, as shown in Figure 16.

[0071] Therefore, the narrow portion 4 is sandwiched between the first locking portions 11A to 11C and the covers 14C and 15C, and the pressing force from the wedge members 14 and 15 causes the first locking portions 11A to 11C and the covers 14C and 15C to be pressed against the narrow portion 4, so that, as in the first embodiment, the generation of abnormal noise can be suppressed.

[0072] Note that components identical to those in the above-described embodiments are denoted by the same reference numerals. Therefore, redundant explanations are omitted in this embodiment. (Other embodiments) In the embodiment described above, the magnet 12F was provided on the second locking plate 12. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which the magnet 12F is provided on at least one of the first locking plate 11 and the second locking plate 12, or a configuration in which either plate is entirely a magnet.

[0073] In the above-described embodiment, a magnet 12F and wedge members 14 and 15 were used as sources of pressing force to press the clamping portion 12E and the first locking portions 11A to 11C against the narrow portion 4. However, the disclosure is not limited thereto.

[0074] In other words, the disclosure may include, for example, a configuration that utilizes elastic force such as a spring as the source of pressing force, a configuration that eliminates the magnet 12F and uses only the wedge members 14 and 15 as the source of pressing force, or a configuration that eliminates the wedge members 14 and 15 and uses only the magnet 12F as the source of pressing force.

[0075] Furthermore, the source of the pressing force is eliminated, and the fit between the rising parts 13A and 13B and the through holes 12G and 12H may be an intermediate fit with a gap of 0 or less. This can suppress the generation of abnormal noise due to the frictional force generated between the rising parts 13A and 13B and the through holes 12G and 12H.

[0076] In the first to fourth embodiments described above, the second locking plate 12 was formed by integrating the second locking portions 12A to 12D and the clamping portion 12E. However, the disclosure is not limited thereto. That is, in this disclosure, for example, the second locking portions 12A to 12D and the clamping portion 12E may each be composed of separate plates.

[0077] In this configuration, it is preferable that the magnet 12F is provided on at least one of the clamping portion 12E and the first locking plate 11, that the magnet 12F is eliminated and the clamping portion 12E is pressed against the wedge members 14, 15, and 17, or that the above-mentioned frictional force is utilized.

[0078] In the first to fourth embodiments described above, the clamping portion 12E was formed in a strip-like shape to constitute a cover. However, the disclosure is not limited thereto. That is, the disclosure may, for example, be a shape that extends in a protruding manner from each of the second locking portions 12A to 12D.

[0079] The wire portion 13 according to the above embodiment was configured in a roughly U-shape or C-shape. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a roughly L-shaped wire portion 13 with a single rising portion.

[0080] The wedge members 14 and 15 in the above-described embodiment were constructed having frames 14B and 15B and covers 14C and 15C, etc. However, this disclosure is not limited thereto. That is, the disclosure may also include, for example, wedge members in which the covers 14C and 15C have been eliminated, or wedge members made entirely of resin.

[0081] In the embodiments described above, a plurality of substantially disc-shaped first and second locking portions were provided. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which one substantially disc-shaped first locking portion and one substantially disc-shaped second locking portion are provided, or a configuration in which substantially rectangular disc-shaped first and second locking portions are provided.

[0082] In the above-described embodiment, the engaging member 16 was indirectly connected to the wedge members 14 and 15 via member 5. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which the engaging member 16 is directly connected to the wedge members 14 and 15.
