[0003] [Patent Document 1] China Utility Model Publication No. 215204687 Summary of the Invention [Problem to be solved by the invention]

[0004] In the mounting structure of the hook member described in the above Patent Document 1, although the hook member can be easily mounted, its load capacity is small, and there is a risk that the hook will come off from the mounted member when a relatively heavy object is hung. On the other hand, in order to increase the load capacity of the hook, a structure may be used in which the interior material is attached to the body and then the hook is fixed to the body. In this case, it is necessary to align the mounting position of the interior material with the mounting position of the body. Also, in order to hide the fasteners used for fixing from the interior material side, a new member is required or the hook member needs to be divided. In other words, in the case of a structure in which the hook is fixed to the body, there is a problem that the workability is deteriorated, such as an increase in the number of work steps and parts in the process of assembling the body and the interior material.

[0005] The present invention has been made in consideration of such circumstances, and has an object to provide a hook member mounting structure that ensures sufficient load resistance while allowing easy mounting work. [Means for solving the problem]

[0006] In order to solve the above problems, the mounting structure of a hook member disclosed in the present application has the following configuration. (1) A mounting structure for a hook member for attaching a hook member for hanging an object to an interior material for a vehicle, comprising: The vehicle interior material covers the inside of a vehicle compartment on a side of an opening formed in a body of the vehicle, and has a mounting hole for mounting the hook member, A covering member is attached to the edge of the opening in a longitudinal direction along the edge and sandwiches and covers the edge from both sides in a thickness direction, the hook member is connected to a backing member disposed on a back surface side of the vehicle interior material through the mounting hole, and thereby the vehicle interior material is attached in a manner that the vehicle interior material is sandwiched between the hook member and the backing member, The backing member has an extension portion that extends toward the opening and has a tip that overlaps with the rim portion, The hook member mounting structure, wherein the covering member, together with the rim portion, sandwiches the extending portion of the backing member.

[0007] The hook member mounting structure disclosed in the present application has a configuration in which the hook member is fixed to the vehicle interior material, but the covering member holds the extension portion, which is one end of the backing member connected to the hook member, so that the load-bearing capacity of the hook member can be increased. For example, there is a structure in which the hook member is fixed to the body to ensure the load-bearing capacity of the hook member, but in such a structure, the hook member is attached after the vehicle interior material is assembled to the body, so that it takes time to align the mounting hole of the vehicle interior material with the mounting portion of the body, and since the fixing is performed from the inside of the vehicle, parts and structures are required to hide the fixing tool used for the fixing. In the hook member mounting structure disclosed in the present application, the hook member is fixed to the vehicle interior material, and then the vehicle interior material to which the hook member is fixed is assembled to the body, and the installation of the hook member is completed simply by attaching the covering member in the same manner as in the past. In other words, the hook member mounting structure disclosed in the present application does not increase the number of work steps and parts in the assembly work of the vehicle interior material to the body. Therefore, the hook member mounting structure disclosed in the present application makes the installation work easy while ensuring sufficient load resistance. In addition, the hook member mounting structure disclosed in the present application can easily accommodate changes in the design of the vehicle interior material even if they occur during the process.

[0008] Furthermore, the above-described hook member mounting structure can be modified in various ways as described below.

[0009] (2) The mounting structure for a hook member described in (1), wherein the extension portion of the backing member is bifurcated at the tip side and has an upper overlapping portion that extends upward from the mounting hole and overlaps with the rim portion, and a lower overlapping portion that extends downward from the mounting hole and overlaps with the rim portion.

[0010] In the mounting structure of the hook member of this configuration, the backing member is held on both the upper and lower sides of the fixed point of the hook member, so that the moment acting on the backing member when an article is hooked on the hook member can be firmly supported.

[0011] (3) The vehicle interior material has a first mounting hole and a second mounting hole as the mounting holes, the backing member has a first through hole and a second through hole formed therethrough corresponding to the first mounting hole and the second mounting hole, the hook member has a hook body and a protrusion protruding from the hook body, and is fastened to the backing member and the vehicle interior material by a fastener inserted into the first mounting hole and the first through hole from the back surface side of the backing member so as to sandwich the backing member and the vehicle interior material; The hook member mounting structure according to item (1) or (2), wherein the protrusion is fitted into the second mounting hole and the second through hole.

[0012] The hook member mounting structure having this configuration can fix the hook member to the vehicle interior material with the minimum number of parts required, and the presence of the protrusion can restrict rotation of the hook member around the fastener.

[0013] (4) The vehicle interior material has an opposing surface portion that forms a surface facing the body, and a standing wall portion that stands from a side edge of the opposing surface portion toward the rim portion, and the mounting hole is formed in the standing wall portion, and the hook member is attached through the mounting structure described in any one of (1) to (3).

[0014] In the hook member mounting structure of this configuration, the location where the mounting hole is formed is relatively close to the rim of the body, so the length of the extension can be relatively short, allowing the backing member to be made smaller.

[0015] (5) The hook member mounting structure according to any one of (1) to (4), wherein a cushioning material is provided on the surface of the extension of the backing member facing the rim portion.

[0016] This configuration of the hook member mounting structure prevents friction between the rim of the body and the extension of the backing member, and the force with which the covering member clamps between the rim and the extension is increased by the thickness of the cushioning material, allowing the backing member to be firmly held in place.

[0017] (6) The body has two openings for two side doors arranged in a row, and a pillar extending in the vertical direction is formed between the two openings. The mounting structure for a hook member according to any one of (1) to (5), wherein the vehicle interior material is a pillar garnish that covers the interior side of the vehicle compartment of the pillar.

[0018] (7) The mounting structure for a hook member described in (6), wherein the covering member is a weather strip that seals the gap between the edge portion and the pillar garnish and prevents water from entering between the edge portion and the side door. Effect of the Invention

[0019] According to the present invention, it is possible to provide a mounting structure for a hook member that ensures sufficient load resistance while allowing easy mounting work. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] A mounting structure for a hook member according to an embodiment of the present invention will be described in detail with reference to Figures 1 to 6. In some of the drawings, directions are indicated using the symbols Fr, Rr, IN, OUT, U, and D, which respectively indicate the front side, rear side, inside and outside of the passenger compartment (vehicle compartment) in the vehicle width direction, the upper side, and the lower side.

[0022] The mounting structure of the hook member of this embodiment is adopted in a vehicle (automobile) 10. The vehicle 10 has two side doors arranged side by side in the front-rear direction, and as shown in Figs. 1 and 2, the vehicle 10 is formed with openings 11, 12 for the side doors. The vehicle 10 has a pillar (so-called B pillar, center pillar) 14 formed between the two openings 11, 12, which extends downward from a ceiling 13. A hook member 16 is provided on the pillar 14, and this embodiment is characterized by the mounting structure of the hook member 16.

[0023] The pillar 14 includes a pillar panel 20 (see FIG. 3) that constitutes the body, and a pillar garnish 22 that covers the interior side of the vehicle interior of the pillar panel 20. In other words, the pillar garnish 22 is a vehicle interior material that covers the interior side of the vehicle interior (vehicle interior side) on the side of the opening 12 formed in the body of the vehicle 10.

[0024] The pillar panel 20 is made up of a plurality of metal panel members. As shown in Fig. 3, the pillar panel 20 is made up of an inner panel 24 arranged inside the vehicle cabin, an outer panel 25 arranged outside the vehicle cabin, and a reinforcement panel 26 arranged between them. The vehicle front and rear side end portions of the inner panel 24, the reinforcement panel 26, and the outer panel 25 are overlapped with each other, and between the both side end portions, the inner panel 24 bulges toward the vehicle cabin, and the outer panel 25 bulges toward the vehicle cabin outside. As a result, the pillar panel 20 as a whole is cylindrical.

[0025] The pillar garnish 22 extends vertically along the pillar panel 20. As shown in FIG. 3, the pillar garnish 22 is made of a base material 28 made of a synthetic resin material such as polypropylene, and a skin material 29 that covers the surface of the base material 28. The pillar garnish 22 has a shape including an opposing surface portion 30 that forms a surface facing the pillar panel 20 (specifically, the inner panel 24), and a pair of standing wall portions 32 that stand from both side edges (both edges in the vehicle front-rear direction) of the opposing surface portion 30 toward the pillar panel 20. As a result, the pillar garnish 22 is attached in a manner that covers the pillar panel 20 so that a space is formed between the opposing surface portion 30 and the pillar panel 20.

[0026] A weather strip 34 is attached to the side end 20a of the pillar panel 20, which is the overlapping portion of the inner panel 24, the outer panel 25, and the reinforcement panel 26 on both sides (only the rear side end is shown in FIG. 3). The weather strip 34 is elongated and extends along the side end 20a of the pillar panel 20 and also along the edge of the roof panel of the ceiling 13. In other words, the weather strip 34 is elongated and extends along the rim of the opening 12 of the body, and corresponds to a covering member that covers the rim. The weather strip 34 is mainly made of an elastic material such as rubber, and is intended to prevent water from entering between the body (including the pillar panel 20) and the side door. The weather strip 34 has a strip main body portion 35, a clamping portion 36, and a lip portion 37. The clamping portion 36 has a generally U-shaped cross section, and the weatherstrip 34 is attached to the clamping portion 36 so as to clamp the side end portion 20a of the pillar panel 20 from both sides in the thickness direction (inside and outside the vehicle). When the weatherstrip 34 is attached to the pillar panel 20, the strip main body portion 35 is located on the outside of the vehicle compartment of the side end portion 20a and contacts the side door to prevent water from entering, and the lip portion 37 hangs on the vertical wall portion 32 of the pillar garnish 22 to prevent a gap between the pillar panel 20 and the pillar garnish 22.

[0027] The weatherstrip 34 is composed of a strip main body member 34a made of an elastic material such as rubber, and a core material 34b formed from a metal plate. A space 34a1 is formed along the longitudinal direction in the portion of the strip main body member 34a where the clamping portion 36 is formed, and the core material 34b is housed in the space 34a1. In other words, the clamping portion 36 clamps the side end portion 20a of the pillar panel 20 with the core material 34b open, and the weatherstrip 34 is attached to the pillar panel 20 by the elastic force of the core material 34b.

[0028] Next, the mounting structure of the hook member 16 will be described in detail with reference to Figs. 4 to 6. The hook member 16 is provided on the standing wall portion 32 on the rear side of the pillar garnish 22. The standing wall portion 32 is formed with two first and second mounting holes 40 and 42 aligned in the vertical direction, and the hook member 16 is mounted by using the first and second mounting holes 40 and 42. More specifically, the hook member 16 is fastened (connected) to a backing bracket (backing member) 44 arranged on the back side of the standing wall portion 32, so that the hook member 16 is mounted in a manner that the standing wall portion 32 is sandwiched between the backing bracket 44 and the hook member 16. The backing bracket 44 is formed with a first through hole 46 and a second through hole 48 so that their positions match those of both the first mounting hole 40 and the second mounting hole 42.

[0029] The hook member 16 has a hook body 50, a boss portion 51, and a protrusion portion 52. The hook body 50 is generally L-shaped and includes a base portion 50a that contacts the surface of the vertical wall portion 32 and a hooking portion 50b that extends upward from the tip of the base portion 50a. As shown in FIG. 6, the base portion 50a has a shape that opens toward the vertical wall portion 32, and the boss portion 51 and the protrusion portion 52 are formed inside the base portion 50a so as to protrude further from the tip of the base portion 50a. The boss portion 51 and the protrusion portion 52 are arranged in the vertical direction, with the boss portion 51 being arranged on the upper side and the protrusion portion 52 being arranged on the lower side.

[0030] The boss portion 51 is cylindrical and is fitted into the first mounting hole 40 of the vertical wall portion 32, passes through the first mounting hole 40, and has a tip abutting the backing bracket 44. More specifically, the tip of the boss portion 51 abuts against the hole edge of the first through hole 46 of the backing bracket 44, and a screw 54, which is a fastener, is inserted through the first through hole 46 and screwed into the boss portion 51. The protrusion portion 52 has a tapered shape and is fitted into the second mounting hole 42 of the vertical wall portion 32 and the second through hole 48 of the backing bracket 44, with the tip protruding from the back surface of the backing bracket 44. When attaching the hook member 16 to the pillar garnish 22, the boss portion 51 and the first through hole 46 of the backing bracket 44 can be aligned by inserting the protrusion portion 52 into the second mounting hole 42 and the second through hole 48, and the screw 54 can be easily screwed in. Furthermore, when the hook member 16 is attached to the pillar garnish 22, the presence of the protrusion 52 makes it possible to prevent the hook member 16 from rotating around the axis of the screw 54 relative to the pillar garnish 22.

[0031] 3 to 5, the backing bracket 44 has a backing portion 60 formed along the vertical wall portion 32, an upper extension portion 62 extending from a portion of the backing portion 60 above the first through hole 46 toward the opening 12, and a lower extension portion 64 extending from a portion of the backing portion 60 below the first through hole 46 toward the opening 12. As shown in FIGS. 3 and 4, the upper extension portion 62 and the lower extension portion 64 are generally U-shaped in top view, and their tips extend along the side end portion 20a of the pillar panel 20. That is, the tips of the upper extension portion 62 and the lower extension portion 64 function as an upper overlap portion 62a and a lower overlap portion 64a that overlap the side end portion 20a of the pillar panel 20, respectively.

[0032] As shown in FIG. 3, the side overlapping portion 62a and the lower overlapping portion 64a are sandwiched by the clamping portion 36 of the weatherstrip 34 together with the side end portion 20a of the pillar panel 20. In other words, the weatherstrip 34 holds the upper overlapping portion 62a and the lower overlapping portion 64a, which are the ends of the backing bracket 44 connected to the hook member 16, and the load-bearing capacity of the hook member 16 can be increased. Incidentally, nonwoven fabrics 66, 67, which are cushioning materials, are wrapped around the upper overlapping portion 62a and the lower overlapping portion 64a. This makes it possible to prevent friction between the pillar panel 20 and the upper overlapping portion 62a and the lower overlapping portion 64a. In addition, the clamping force by the clamping portion 36 of the weatherstrip 34 is increased by the thickness of the nonwoven fabrics 66, 67, and the backing bracket 44 can be firmly held.

[0033] Moreover, when an object to be hung is hooked on hook member 16, a forward and downward force (clockwise moment in FIG. 6) acts on backing bracket 44 from the fastening point (screw 54) of hook member 16. In the mounting structure of hook member 16 of this embodiment, as shown in FIGS. 5 and 6, backing bracket 44 is held on both the upper and lower sides of the fastening point, so that the above-mentioned force (moment) can be firmly supported, further increasing the load resistance.

[0034] In addition, the manufacturing process of the vehicle 10 employing the mounting structure of the hook member 16 of this embodiment is performed in the following order. First, the hook member 16 is fastened to the pillar garnish 22 together with the backing bracket 44. Then, the pillar garnish 22 to which the hook member 16 is attached is assembled to the pillar panel 20. Next, the weather strip 34 is attached. For example, there is a structure in which the hook member is fixed to the pillar panel to ensure the load resistance of the hook member, but in such a structure, the hook member 16 is attached after the pillar garnish is assembled to the pillar panel. Therefore, it is time-consuming to align the mounting hole of the pillar garnish with the mounting part on the pillar panel side, and parts or structures are required to hide the fasteners used for the fastening in order to perform the fastening from the inside of the vehicle compartment. In other words, according to the mounting structure of the hook member 16 of this embodiment, the process of assembling the pillar garnish 22 to the pillar panel 20 does not increase the number of work steps and parts. Therefore, the mounting structure of the hook member 16 of this embodiment ensures sufficient load resistance while facilitating the mounting work. Furthermore, according to the mounting structure of the hook member 16 of this embodiment, even if a change occurs in the design of the pillar garnish 22 during the course of its design, it is possible to easily accommodate the change, for example, by simply changing the shape of the backing bracket 44 in accordance with the design change.

[0035] <Other embodiments> The present invention is not limited to the above-described embodiment, but can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art.

[0036] In the above embodiment, the hook member 16 and the backing bracket 44 are fastened together by the screw 54, but the structure for connecting the hook member 16 and the backing bracket 44 is not particularly limited.

[0037] In the above embodiment, a weather strip 34 was used as a covering member for covering the side end portion 20a of the pillar panel 20 which serves as the edge portion of the opening 12, but the covering member may simply be a molding member for covering the side end portion 20a.

[0038] In the above embodiment, the extension of the backing bracket 44 is bifurcated, but the shape is not limited to this. For example, the shape can be determined in consideration of the load capacity and the positional relationship between the hook member and the rim.

[0039] In the above embodiment, the mounting structure of the hook member 16 to the B-pillar 14 of an automobile has been exemplified, but the present invention can be applied to mounting structures of hook members to pillars of other vehicles, trains, airplanes, ships, etc. In addition, in those vehicles, when the opening of the body and the vehicle interior material are in the same positional relationship as in this embodiment, the mounting structure of the present invention can also be applied when attaching a hook member to the vehicle interior material.
