[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. The following preferred embodiments are merely examples, and the present invention is not limited to the preferred embodiments.

[0010] <Embodiment 1> Fig. 1 is an exploded perspective view showing the structure of the ceiling side for mounting an in-vehicle device. Fig. 1 shows a reinforcing member 1, such as a so-called reinforcement, that is placed inside the ceiling of an automobile, and two brackets 2. Note that the interior of the ceiling is omitted, but the portion of the reinforcing member 1 where the in-vehicle device is mounted is exposed inside the vehicle cabin. In addition, the reinforcing member 1 is provided with four female threads 11 for fastening the brackets 2.

[0011] Bracket 2 is a mounting member formed by bending a metal plate made of a predetermined material and drilling holes at predetermined positions. Bracket 2 has first, second, and third surfaces 21, 22, and 23 that are U-bent so that the cross section is, for example, U-shaped, and fourth surface 24 that is formed by L-bending third surface 24 so that the cross section is L-shaped. Two through holes 25 are formed in second surface 22 at positions corresponding to female thread portion 11 of reinforcing member 1, for inserting bolts 41 that thread into female thread portion 11. Two through holes 26 are formed in fourth surface 24, for inserting bolts 42 for mounting an in-vehicle device. Furthermore, hook portions 27 are formed in fourth surface 24 by Z-bending a tongue portion that has been laser-cut into, for example, a U-shape.

[0012] With the bolt 42 inserted into the through hole 26, the bracket 2 is fastened to the reinforcing member 1 by threading the bolt 41 inserted into the through hole 25 into the female thread portion 11 of the reinforcing member 1. At this time, the heads of the bolts 41 and 42 fit within the space defined by the sizes of the first surface 21 and the third surface 23. Note that at least some of the bolts 41 and 42 may be stud bolts. In this case, the bracket 2 has a female thread portion, and does not need to be bent to form a space to accommodate the head of the bolt 41 or bolt 42. Furthermore, a male thread portion may be connected to the bracket 2 by welding or the like. As described above, the bracket 2 is configured to have a male thread portion.

[0013] FIG. 2 is a perspective view showing a state before the in-vehicle device is installed. The top and bottom directions are shown with the ceiling side facing up. In the example of FIG. 2, bracket 2 is connected to reinforcing member 1 by bolt 41. Bolt 42 is inserted into through-hole 26 with the male thread portion facing downward. Hook portion 27 includes hanging portion 271 extending downward, and support portion 272 bending from the lower end of hanging portion 271 and extending in a substantially horizontal direction. Support portion 272 of hook portion 27 extends in a direction connecting two through-holes 26.

[0014] The in-vehicle device 3 is a device mounted on the ceiling of the vehicle interior, such as an RSE (Rear Seat Entertainment) system. The in-vehicle device 3 is a device to be installed in a vehicle. Note that in this embodiment, a panel portion including a mounting portion connected to the ceiling side is shown, and a flip-down monitor and the like are omitted. The mounting portion of the in-vehicle device 3 includes a first oblong hole 31 into which the hook portion 27 can be inserted and a second oblong hole 32 into which the male thread portion of the bolt 42 can be inserted. Note that the in-vehicle device 3 includes two second oblong holes 32 on each of the left and right sides. The first oblong holes 31 and the second oblong holes 32 are formed so that their longitudinal directions are aligned in a straight line. Although reference numerals are omitted in FIG. 2 , the in-vehicle device 3 includes the first oblong holes 31 and the second oblong holes 32 symmetrically on the left and right sides, and the left and right mounting portions are connected to the bracket 2, respectively.

[0015] Fig. 3 is a schematic cross-sectional view showing an example of a method for installing an in-vehicle device. Fig. 3(A) shows a state before the in-vehicle device 3 is installed. At the stage of Fig. 3(A), an operator supports the in-vehicle device 3 by aligning the first elongated hole 31 and the second elongated hole 32 of the in-vehicle device 3 with the hook portion 27 and the male thread portion of the bolt 42, respectively, as shown in Fig. 2.

[0016] 3B shows the process of inserting the hook portion 27 and the male thread portion of the bolt 42 into the first oblong hole 31 and the second oblong hole 32 of the in-vehicle device 3, respectively. FIG. 4 is a perspective view showing the state in which the hook portion and the bolt have been inserted into the mounting portion of the in-vehicle device. In FIG. 3B, the state is as shown in FIG. 4. The support portion 272 of the hook portion 27 extends in the direction connecting the two bolts 42, and the support portion 272 of the hook portion 27 and the male thread portion of the bolt 42 pass through the first oblong hole 31 and the second oblong hole 32, respectively.

[0017] FIG. 3C illustrates a process of inserting hook portion 27 and bolt 42 into the mounting portion of in-vehicle device 3, and then sliding in-vehicle device 3 in a second direction opposite to the first direction in which support portion 272 of hook portion 27 extends. In FIG. 3, the right side corresponds to the first direction, and the left side corresponds to the second direction. FIG. 5 is a perspective view illustrating the in-vehicle device in a slid state. Since in-vehicle device 3 is slid with hanging portion 271 of hook portion 27 and the male thread portion of bolt 42 inserted into first elongated hole 31 and second elongated hole 32, respectively, the movement direction is guided by hanging portion 271 of hook portion 27 and the male thread portion of bolt 42. Furthermore, these components are provided at a position and with a size such that the male thread portion of bolt 42 abuts against the edge of second elongated hole 32 in the first direction before hanging portion 271 of hook portion 27 abuts against the edge of first elongated hole 31 in the first direction. That is, the first-direction end of the hanging portion 271 relative to the first-direction end of the male thread portion of the bolt 42 is located closer to the second direction than the first-direction edge of the first oblong hole 31 relative to the first-direction edge of the second oblong hole 32. When the first-direction end of the second oblong hole 32 is brought into contact with the male thread portion, the hanging portion 271 of the hook portion 27 is spaced apart from the end of the first oblong hole. Furthermore, in this state, the tip of the support portion 272 is located closer to the first direction than the first-direction end of the first oblong hole. Therefore, even if the worker does not support the in-vehicle device 3, the edge of the first oblong hole 31 of the in-vehicle device 3 engages with the support portion 272, and the in-vehicle device 3 is supported by the support portion 272.

[0018] FIG. 3D shows a process of fastening the in-vehicle device 3 to the bracket 2. FIG. 6 is a perspective view showing the state in which the in-vehicle device and the bracket are fastened. In the examples of FIG. 3D and FIG. 6, the nut 43 is screwed onto the male thread of the bolt 42, connecting the bracket 2 to the in-vehicle device 3. At this time, the engagement between the support portion 272 and the first elongated hole 31 is released. Since there are combinations of bolts 42 and nuts 43 at two locations per bracket 2, for a total of four locations, sufficient strength can be ensured.

[0019] As described above, the worker does not need to support the in-vehicle device 3, and the task of fixing the in-vehicle device 3 to the ceiling is facilitated. Furthermore, since the mounting position of the in-vehicle device 3 is aligned using the male thread portion of the bolt 42 and the end of the second elongated hole 32, the dimensional accuracy required for the bending of the hanging portion 271 and the support portion 272 of the hook portion 27 is not very high. Furthermore, since the final connection between the in-vehicle device 3 and the bracket 2 is performed using bolts and nuts, the strength required for the hook portion 27, which is used temporarily, is not very high. Therefore, the mounting structure between the bracket 2 and the in-vehicle device 3 shown in this embodiment can be said to be a simple one that allows for temporary fixing.

[0020] <Variation 1> FIG. 7 is a schematic cross-sectional view showing a method for mounting an in-vehicle device according to a modified example. FIG. 7 shows the process from step (C) onward in FIG. 3. In this modified example, the configuration of the mounting portion of the bracket 2 and the in-vehicle device 3 is the same as described above, so a description thereof will be omitted. In this modified example, the position at which the in-vehicle device 3 and the bracket 2 are fastened is different. In addition, in FIG. 7(C), In this case, as long as the edge of the first elongated hole 31 and the support portion 272 are positioned to engage with each other, the end of the second elongated hole 32 in the first direction and the male thread portion do not necessarily have to abut against each other.

[0021] 7(E) shows a process of partially threading the nut 43 into the male thread portion of the bolt 42 after the in-vehicle device 3 is supported by the support portion 272 of the hook portion 27. In this process, the in-vehicle device 3 is supported by the nut 43, and the engagement between the support portion 272 and the first elongated hole 31 is released. This process can also be performed by an operator without supporting the in-vehicle device 3. In particular, because there are combinations of bolts 42 and nuts 43 at two locations per bracket 2, for a total of four locations, the posture of the in-vehicle device 3 is stable even in the temporarily fixed state, and sufficient strength can be ensured.

[0022] 7(F) shows a process of sliding the in-vehicle device 3 in the first direction after the nut 43 has been partially threaded onto the male thread portion of the bolt 42. In FIG. 7 as well, the right side corresponds to the first direction and the left side corresponds to the second direction. In this process as well, the in-vehicle device 3 is slid with the hanging portion 271 of the hook portion 27 and the male thread portion of the bolt 42 inserted into the first oblong hole 31 and the second oblong hole 32, respectively, and therefore the movement direction is guided by the hanging portion 271 of the hook portion 27 and the male thread portion of the bolt 42. Furthermore, these components are provided at a position and with a size such that the male thread portion of the bolt 42 abuts against the edge of the second direction of the second oblong hole 32 before the hanging portion 271 of the hook portion 27 abuts against the edge of the first oblong hole 31 in the second direction. In other words, the second-direction end of the hanging portion 271 relative to the second-direction end of the male thread portion of the bolt 42 is located closer to the first direction than the position of the second-direction edge of the first long hole 31 relative to the second-direction edge of the second long hole 32.

[0023] Fig. 7(G) shows the process of fastening the in-vehicle device and the bracket. In the example of Fig. 7(G), the nut 43, which was threaded partway into the male thread of the bolt 42, is threaded all the way in, connecting the bracket 2 and the in-vehicle device 3.

[0024] In this modified example, the mounting position of the in-vehicle device 3 is aligned by the male thread portion of the bolt 42 and the end of the second elongated hole 32, so the dimensional accuracy required for the bending of the hanging portion 271 and the support portion 272 of the hook portion 27 is not very high. Furthermore, the final connection between the in-vehicle device 3 and the bracket 2 is performed with bolts and nuts, so the strength required for the hook portion 27 is not very high. Therefore, the mounting structure between the bracket 2 and the in-vehicle device 3 shown in this embodiment can be said to be a simple one that can be temporarily fixed.

[0025] Whether to align the male thread portion of the bolt 42 with the end of the second elongated hole 32 in the first direction as in the embodiment described above, or to align the male thread portion of the bolt 42 with the end of the second elongated hole 32 in the second direction as in the modified example, can be selected appropriately at the time of design. Note that if, as in the modified example, the bracket 2 and the on-vehicle device 3 are fastened together at a position where the hook portion 27 does not interfere with the mounting portion of the on-vehicle device 3, it becomes easier to verify at the time of design whether the clearance between the hook portion 27 and surrounding members is sufficient.

[0026] <Variation 2> Fig. 8 is a diagram showing an example of a bracket with an indication to show whether alignment is complete or not. The bracket 2 shown in Fig. 8 is a bottom view seen from inside the vehicle cabin when connected to the reinforcing member 1. In Fig. 8, the first oblong hole 31 and the second oblong hole 32 are indicated by dashed lines. Fig. 8(A) shows a state in which the male thread portion of the bolt 42 is in contact with the edge of the second oblong hole 32 in the second direction. Fig. 8(B) shows a state in which the male thread portion of the bolt 42 is in contact with the edge of the second oblong hole 32 in the first direction.

[0027] The bracket 2 shown in FIG. 8 is provided with a marking 28, which is, for example, a marking. 8 includes a first indicator 281 provided at a position visible from the first elongated hole 31 of the vehicle-mounted device 3 when the male threaded portion of the bolt 42 is abutted against the edge of the second elongated hole 32 in the second direction, and a second indicator 282 provided at a position visible from the first elongated hole 31 of the vehicle-mounted device 3 when the male threaded portion of the bolt 42 is abutted against the edge of the second elongated hole 32 in the first direction.

[0028] Only one of the first marking and the second marking may be provided. In the case where only one of them is provided, the marking 28 may be visible when the alignment for fastening the in-vehicle device 3 and the bracket 2 is completed, or may be invisible when the alignment is completed, depending on the design such as the above-described embodiment or variant 1. The shape of the marking 28 is not limited to an arrow, and may be any character, figure, symbol, color, etc. Furthermore, the marking 28 may be visible from the second elongated hole 32 in any of the above-described states.

[0029] According to the display 28 of this modified example, the worker can visually recognize whether or not the alignment is complete, and attachment in an incorrect position can be prevented.

[0030] Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these. Various modifications based on the knowledge of those skilled in the art are possible without departing from the spirit of the claims. For example, the number and arrangement of the bolt slots, their relative positions to the hook portion 27, etc. can be modified as appropriate. [Explanation of symbols]
