[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-046902 Summary of the Invention [Problem to be solved by the invention]

[0004] As shown in Patent Document 1, a mounting body can be attached to an opening in a ceiling material body by inserting and locking a spacer between the back surface of the ceiling material body and a protrusion. However, when attaching the same mounting body to a ceiling material body with a different thickness on the front and back, a separate spacer that matches the dimension between the protrusion and the back surface of the ceiling material body is required. As such, a structure that uses spacers increases the number of spacer parts, increasing material costs and making the assembly work of placing the spacers complicated.

[0005] An object of the present invention is to provide a mounting structure that is versatile enough to accommodate different thicknesses of mounting portions. [Means for solving the problem]

[0006] In order to achieve the above object, one embodiment of the mounting structure of the present invention has a first member and a second member that are attached to the mounting portion by sandwiching the mounting portion in the thickness direction, the first member is provided with a fixing portion that fixes the second member, and the second member is provided with a plurality of engaging portions that engage with the fixing portion of the first member at different heights in the thickness direction of the mounting portion. [Effects of the Invention]

[0007] According to the present invention, attachment can be made according to differences in the thickness of the attachment portion. [Brief explanation of the drawings]

[0009] Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the components disclosed in the following embodiments can be combined as appropriate.

[0010] 1 to 3, the mounting structure of the embodiment is applied, for example, to mount a drive recorder 100, which is an attachment, to a ceiling interior material 10 of a vehicle, which is an attachment portion. The mounting structure is not limited to application to the above-mentioned attachment portion and attachment portion.

[0011] The ceiling interior material 10 has a predetermined thickness T, and an opening 10A is provided penetrating in the direction of thickness T to apply the mounting structure of the embodiment.

[0012] The mounting structure has a first member 1 and a second member 2. A drive recorder 100, which is an attachment body, is connected to the first member 1. The mounting structure is attached to the ceiling interior material 10 by sandwiching the ceiling interior material 10 between the first member 1 and the second member 2 in the thickness T direction, thereby mounting the drive recorder 100 connected to the first member 1 to the ceiling interior material 10.

[0013] The base portion of the first member 1 is formed in a substantially rectangular plate shape. The first member 1 has an outer shape larger than the opening dimensions of the opening 10A of the ceiling interior material 10, and its outer peripheral edge 1A can abut against the opening edge of the opening 10A. The first member 1 has an annular fitting protrusion 1B formed along its outer peripheral edge 1A. The fitting protrusion 1B is inserted into and fitted into the opening 10A. The first member 1 is positioned relative to the opening 10A by inserting and fitting the fitting protrusion 1B into the opening 10A. The first member 1 also includes a fixing portion 1C and a guide protrusion 1D.

[0014] The fixing portion 1C is formed on the same plate surface 1a of the first member 1 as the fitting protrusion 1B. The fixing portion 1C is formed in a cylindrical shape protruding from the plate surface 1a of the first member 1 within the annular shape of the fitting protrusion 1B. The fixing portion 1C has a through hole 1Cb formed from the protruding tip surface 1Ca through the plate thickness of the plate-shaped first member 1. The fixing portion 1C is formed at multiple locations (two locations in this embodiment) on the plate surface 1a of the first member 1. As shown in FIGS. 5 and 6, the fixing portion 1C is arranged on a diagonal of the rectangular shape of the first member 1, which is formed in a substantially rectangular shape.

[0015] The guide protrusion 1D is formed on the same plate surface 1a as the fitting protrusion 1B and the fixing portion 1C. The guide protrusion 1D is formed in the shape of a plate protruding from the plate surface 1a of the first member 1. The guide protrusion 1D is provided in a position within the annular shape of the fitting protrusion 1B where the fixing portion 1C is not provided. In this embodiment, the guide protrusion 1D is provided between the two fixing portions 1C and parallel to the long side of the substantially rectangular shape of the first member 1.

[0016] 1 to 6, the second member 2 has a base portion formed in a substantially rectangular plate shape, the base portion having a first plate surface 2a and a second plate surface 2b. The second member 2 has an outer shape larger than the opening dimensions of the opening 10A in the ceiling interior material 10, and the first plate surface 2a or the second plate surface 2b can abut against the opening edge of the opening 10A. The second member 2 includes multiple types of engaging portions (2A, 2B, 2C) and a guide hole 2D.

[0017] In this embodiment, the engaging portion has three types: a first engaging portion 2A, a second engaging portion 2B, and a third engaging portion 2C.

[0018] The first engagement portion 2A has first screw holes 2Aa that penetrate the second member 2 by the thickness thereof and appear on the first plate surface 2a and the second plate surface 2b. As shown in FIGS. 1 to 3 and 5 , the first screw holes 2Aa are provided at a plurality of locations (two locations in this embodiment) at positions that coincide with the through holes 1Cb of the fixing portion 1C with the second plate surface 2b of the second member 2 facing the tip surface 1Ca of the fixing portion 1C of the first member 1. As shown in FIG. 4 , each of the first screw holes 2Aa is disposed obliquely with respect to the rectangular second member 2. When the first screw holes 2Aa of the first engagement portion 2A coincide with the through holes 1Cb of the fixing portion 1C and engage, the second plate surface 2b of the second member 2, which is the opening edge of the first screw hole 2Aa, abuts against the tip surface 1Ca of the fixing portion 1C. Then, with the first screw hole 2Aa engaged with the through hole 1Cb of the fixing portion 1C, the screw 3 is inserted into the through hole 1Cb and screwed into the first screw hole 2Aa, thereby fixing the second member 2 to the first member 1 with the ceiling interior material 10 sandwiched between them. In this way, the drive recorder 100, which is the mounting body, is attached to the ceiling interior material 10, which is the mounting portion.

[0019] The second engagement portion 2B has a second engagement surface 2Ba that protrudes from the first plate surface 2a in the plate thickness direction by a height H1 (see FIG. 3). The second engagement surface 2Ba can be formed by drawing the second member 2 made of sheet metal. The second engagement portion 2B also has second screw holes 2Bb that penetrate the second member 2 from the second engagement surface 2Ba. As shown in FIG. 6, the second screw holes 2Bb are provided at multiple locations (two locations in this embodiment) at positions that coincide with the through holes 1Cb of the fixing portion 1C, with the first plate surface 2a of the second member 2 facing the tip surface 1Ca of the fixing portion 1C of the first member 1. As shown in FIG. 4, each second screw hole 2Bb and second engagement surface 2Ba is arranged obliquely with respect to the rectangular-shaped second member 2. That is, the second engagement portion 2B inverts the plate surfaces 2a, 2b of the second member 2 relative to the first engagement portion 2A and slides the second member 2 in the longitudinal direction of the rectangular shape, thereby positioning the second screw hole 2Bb in the same position as the first screw hole 2Aa. When the second screw hole 2Bb is aligned with and engaged with the through hole 1Cb of the fixing portion 1C, the second engagement surface 2Ba, which is the opening edge of the second screw hole 2Bb, abuts against the tip surface 1Ca of the fixing portion 1C. As shown in FIG. 6, this second engagement portion 2B is applied to a ceiling interior material 10 having a thickness Ta that is greater by a height H1 than the thickness T of the ceiling interior material 10 shown in FIGS. 1 to 3 and 5. With the second screw hole 2Bb engaged with the through hole 1Cb of the fixing portion 1C, a screw 3 is inserted into the through hole 1Cb and screwed into the second screw hole 2Bb, thereby fixing the second member 2 to the first member 1 with the ceiling interior material 10 sandwiched therebetween. As a result, the drive recorder 100, which is the mounting body, is attached to the ceiling interior material 10 having a thickness Ta, which is the mounting portion.

[0020] The third engagement portion 2C has a third engagement surface 2Ca that protrudes from the second plate surface 2b in the plate thickness direction by a height H2 (see FIG. 3). The height H2 is shorter than the height H1 of the second engagement portion 2B. The third engagement surface 2Ca can be formed by drawing the second member 2 made of sheet metal. The third engagement portion 2C also has third screw holes 2Cb that penetrate the second member 2 from the third engagement surface 2Ca. As shown in FIG. 7, the third screw holes 2Cb are provided at multiple locations (two locations in this embodiment) at positions that coincide with the through holes 1Cb of the fixing portion 1C, with the second plate surface 2b side of the second member 2 facing the tip surface 1Ca of the fixing portion 1C of the first member 1. As shown in FIG. 4, each of the third screw holes 2Cb and the third engagement surface 2Ca is disposed obliquely with respect to the rectangular-shaped second member 2. That is, by sliding the second member 2 in the longitudinal direction of the rectangular shape relative to the first engagement portion 2A, the third screw hole 2Cb of the third engagement portion 2C is positioned in the same position as the first screw hole 2Aa. When the third screw hole 2Cb of the third engagement portion 2C is aligned with and engaged with the through hole 1Cb of the fixing portion 1C, the third engagement surface 2Ca, which is the opening edge of the third screw hole 2Cb, abuts against the tip surface 1Ca of the fixing portion 1C. As shown in FIG. 7, this third engagement portion 2C is applied to a ceiling interior material 10 having a thickness Tb that is thicker by a height H2 than the thickness T of the ceiling interior material 10 shown in FIGS. 1 to 3 and 5. Then, with the third screw hole 2Cb engaged with the through hole 1Cb of the fixing portion 1C, a screw 3 is inserted into the through hole 1Cb and screwed into the third screw hole 2Cb, thereby fixing the second member 2 to the first member 1 with the ceiling interior material 10 sandwiched therebetween. As a result, the drive recorder 100, which is the mounting body, is attached to the ceiling interior material 10 having a thickness Tb, which is the mounting portion. Note that the thickness Tb of the ceiling interior material 10 is smaller than the thickness Ta, and the protruding height H2 of the third engagement portion 2C is smaller than the protruding height H1 of the second engagement portion 2B.

[0021] As shown in FIGS. 1, 2, and 4 to 7, the guide hole 2D is formed as a slit hole extending along the longitudinal direction of the rectangular shape of the second member 2 at a position where it does not interfere with the respective engaging portions 2A, 2B, and 2C. The guide protrusion 1D of the first member 1 is inserted into the guide hole 2D. The guide hole 2D is formed to have a length greater than that of the guide protrusion 1D. As shown in FIGS. 1 to 3 and 5, the guide protrusion 1D is inserted into this guide hole 2D when the second plate surface 2b side of the second member 2 faces the tip surface 1Ca of the fixing portion 1C of the first member 1 and the first screw hole 2Aa of the first engaging portion 2A is aligned with and engaged with the through hole 1Cb of the fixing portion 1C. 6, the guide protrusion 1D is also inserted through the guide hole 2D when the first plate surface 2a side of the second member 2 faces the tip surface 1Ca of the fixing portion 1C of the first member 1 and the second screw hole 2Bb of the second engaging portion 2B is aligned with and engaged with the through hole 1Cb of the fixing portion 1C. The guide protrusion 1D is also inserted through the guide hole 2D when the second plate surface 2b side of the second member 2 faces the tip surface 1Ca of the fixing portion 1C of the first member 1 and the third screw hole 2Cb of the third engaging portion 2C is aligned with and engaged with the through hole 1Cb of the fixing portion 1C. That is, the guide hole 2D and the guide protrusion 1D constitute a guide portion that guides the engagement positions of the engaging portions 2A, 2B, and 2C with the fixing portion 1C in accordance with a change in the position of the second member 2 relative to the first member 1.

[0022] The first member 1 and the second member 2 are attached to the ceiling interior material 10 as follows. For example, the screw 3 inserted into the through hole 1Cb of the fixing portion 1C is loosely screwed into the screw holes 2Aa, 2Bb, and 2Cb of the engaging portions 2A, 2B, and 2C, leaving the gap between the first member 1 and the second member 2 wider than the thickness T of the ceiling interior material 10. Then, the second member 2 is passed through the opening 10A and the screw 3 is tightened, thereby sandwiching the ceiling interior material 10 between the first member 1 and the second member 2 in the thickness T direction. Alternatively, for example, the second member 2 can be passed through the opening 10A and the screw 3 tightened to sandwich the ceiling interior material 10 between the first member 1 and the second member 2 in the thickness T direction.

[0023] As such, the mounting structure of the embodiment has a first member 1 and a second member 2 that are attached to the ceiling interior material (mounting portion) 10 by sandwiching the ceiling interior material 10 in the thickness T direction, and the first member 1 is provided with a fixing portion 1C that fixes the second member 2, and the second member 2 is provided with multiple engaging portions 2A, 2B, 2C that engage with the fixing portion 1C of the first member 1 at different heights in the thickness T direction of the ceiling interior material 10.

[0024] According to this mounting structure, by selecting the engaging portions 2A, 2B, 2C according to the thickness T of the ceiling interior material 10 and engaging them with the fixing portion 1C, the first member 1 and the second member 2 can be sandwiched and mounted in accordance with differences in the thickness T of the ceiling interior material 10. Furthermore, compared to using multiple types of spacers in accordance with differences in the thickness T of the ceiling interior material 10, the mounting structure of the embodiment reduces the number of parts, reduces costs, and makes the mounting work easier.

[0025] In the mounting structure of the embodiment, the engagement portions 2A, 2B, 2C having different heights are provided at positions that allow them to engage with the fixing portion 1C in accordance with changes in the arrangement of the second member 2 relative to the first member 1.

[0026] According to this mounting structure, the engaging portions 2A, 2B, and 2C can be easily selected by changing the arrangement of the second member 2 relative to the first member 1, and the mounting work can be easily performed.

[0027] In addition, the mounting structure of the embodiment has guide portions (guide holes 2D and guide protrusions 1D) that guide the engagement positions of the engagement portions 2A, 2B, and 2C with the fixing portion 1C in accordance with changes in the arrangement of the second member 2 relative to the first member 1.

[0028] According to this mounting structure, the guide portions guide the engagement positions of the engaging portions 2A, 2B, and 2C to the fixed portion 1C, thereby facilitating the engagement and simplifying the mounting work.

[0029] In addition, in the mounting structure of the embodiment, the first member 1 and the second member 2 are engaged with each other through an opening 10A formed in the ceiling interior material 10, and the second member 2 is configured so that it can pass through the opening 10A and be positioned above the mounting portion 10 by changing its orientation when attached from the below of the mounting portion 10.

[0030] According to this mounting structure, the second member 2 is passed through the opening 10A, and the ceiling interior material 10 is sandwiched between the first member 1 and the second member 2 in the thickness T (Ta, Tb) direction and mounted, thereby facilitating the mounting work from the front side of the opening 10A even in conditions where it is difficult to access the back side of the opening 10A.

[0031] In addition, in the mounting structure of the embodiment, the fixing portion 1C forms a through hole 1Cb through which the screw 3 is inserted, and the engaging portions 2A, 2B, and 2C engage with the through hole 1Cb and form screw holes 2Aa, 2Bb, and 2Cb into which the screw 3 is screwed.

[0032] According to this mounting structure, the engagement between the fixing portion 1C and the engaging portions 2A, 2B, and 2C is positioned and engaged with the screws 3, so that the first member 1 and the second member 2 can be easily sandwiched and mounted according to differences in the thickness T (Ta, Tb) of the ceiling interior material 10.

[0033] In the above-described embodiment, it has been described that the ceiling interior material 10 can be adapted to three different thicknesses T (Ta, Tb), but it is also possible to further increase the number of thicknesses of the ceiling interior material 10 that can be adapted by providing additional engaging portions of different heights.
