Technical Field

The present invention relates to a structure (hereinafter referred to as a "hook structure for hanging things") capable of hooking a shopping bag or the like to an interior part for an automobile, and particularly to a hook structure for hanging things which is compact and excellent in rigidity and which is suitable for achieving weight reduction, reduction in the number of parts, and cost reduction of the entire interior part for an automobile.

Background

Conventionally, such an interior part for an automobile has a hook structure for hooking an article on a side trim constituting an inner side surface of a trunk (for example, refer to a hook (4) in an interior part (1) for an automobile disclosed in patent document 1).

Fig. 6 (a) is an explanatory view of a conventional hook structure for hanging articles, and fig. 6 (b) is a cross-sectional view taken along line D of fig. a.

Referring to (a) and (b) of fig. 6, the conventional hook structure 30 for hanging articles includes: an opening 4 opened in the interior trim part 1 for an automobile, and a hook 5 provided at a position slightly protruding outward from the opening, wherein the hook 5 is composed of a hook portion 50 extending in the width direction of the opening 4, and a support piece 54 connected from the hook portion 50 to the inner lower edge portion of the opening 4.

However, in the conventional hook structure 30 for hanging articles as described above, for example, as shown in fig. 7, when the straight distance L1 from the tip end of the support piece 54 to the base thereof is long, and when a shopping bag or the like is hung on the hook portion 50, stress concentrates in the vicinity of the base of the support piece 54, and the support piece 54 is easily bent in the vicinity of the base.

In order to solve the above-described problem (bending of the support piece 54), conventionally, as shown in fig. 8 (a) and (b), the rigidity of the support piece 54 is improved by adopting a structure in which the entire support piece 54 is formed in a crank shape (hereinafter referred to as "conventional first structure"), and in addition, as shown in fig. 9 (a) and (b), a structure in which the vicinity of the root of the support piece 54 is formed into a large R-shaped arc portion (hereinafter referred to as "conventional second structure") is adopted, so that the stress concentrated in the vicinity of the root of the support piece 54 is dispersed.

However, as is clear from comparison between fig. 7 and fig. 8 or fig. 9, when the above-described first and second conventional structures are employed, the linear distance dimension in the vertical (up-down) direction from the vicinity of the base of the support piece 54 to the tip of the hook 50 is H1+ H2 length in (a) and (b) of fig. 9 due to the above-described crank shape and R shape. Further, when the support piece 54 and the hook portion 50 are molded by a die, the length of the opening 4 in the vertical (up-down) direction must be set long in accordance with the linear distance of the opening in the vertical (up-down) direction, and the width of the support piece 54 near the root portion is enlarged by the R-shape, so that the length of the opening 4 in the lateral (width) direction must be set long in accordance with the linear distance. Therefore, in the conventional hook structure for hanging articles 30, when the above-described conventional first and second structures are employed, the entire hook structure for hanging articles 30 must be a large-sized structure.

In the conventional hook structure 30 for hanging articles, as a means for improving the rigidity of the entire hook 5, a structure in which another member such as a bracket is disposed on the back surface of the hook 5 (hereinafter referred to as "another member installation method") is considered (for example, see the "back hook 13" disclosed in patent document 1). However, in this other component installation method, since this other component or another other component necessary for the installation of the other component is necessary, there is a problem that the weight of the entire automobile interior part and the number of components increase, and a problem that the cost of the automobile interior part increases.

Disclosure of Invention

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a hook structure for hanging an article, which is compact and excellent in rigidity, and which is suitable for achieving weight reduction of the entire interior part for an automobile, reduction in the number of parts, and cost reduction.

To achieve the above object, the present invention is characterized in that: the vehicle interior part comprises an opening formed in the vehicle interior part, and a hook provided at a position slightly protruding outward from the opening, wherein the hook comprises: a hook portion extending in a width direction of the opening; a first support part connected to the inner upper edge part of the opening from the hook part; and a second support portion connected to the inner lower edge portion of the opening from the hook portion, and supporting the hook portion from the inner upper and lower edge portions of the opening by the first and second support portions.

In the present invention, a flange portion may be formed on a back surface edge portion in the vertical direction of the hook portion.

In the present invention, a longitudinal rib may be provided on the back surface of the hook.

In the present invention, the vertical rib may be formed in a shape that vertically cuts the hooking portion, the first support portion, and the second support portion to reach an inner upper edge portion and an inner lower edge portion of the opening.

Effects of the invention

In the present invention, as described above, the hook having the structure in which the hook receiving portion is supported from the upper and lower sides of the inner side of the opening by the first and second support portions is adopted as the specific hook structure for hanging articles in the interior trim part for an automobile, and therefore, the following operational effects 1 to 3 can be obtained.

Effect 1

According to the present invention, since the hook is supported by the first and second support portions, the rigidity of the entire hook with respect to the load can be sufficiently ensured even when the entire hook structure for hanging articles is downsized, and the hook structure for hanging articles of automotive interior parts having excellent rigidity can be provided, as compared with the conventional hook in which the hook portion is supported by one support portion.

Effect of action 2

In the present invention, since the stress generated in the hook (the hooking portion and the supporting portion thereof) by the load is not concentrated at one point but is relaxed by being dispersed in the vicinity of the root portions of the first and second supporting portions, that is, the inner upper and lower side portions of the opening (the vertical direction of the hook), it is not necessary to take a conventional countermeasure against such stress (for example, making the entire supporting portion in a crank shape, or forming the vicinity of the both side portions of the opening in a large R shape, or the like), and the width and height of the opening can be set smaller than those of the conventional art.

Effect of action 3

According to the present invention, as described above, even when the entire hook structure for hanging articles is downsized, it is possible to sufficiently secure the rigidity of the entire hook with respect to the load, and therefore, it is not necessary to adopt a conventional measure (addition of another member) for securing the rigidity thereof, and by this, it is possible to provide a hook structure for hanging articles suitable for achieving weight reduction, reduction in the number of components, and cost reduction of the entire interior member for automobile.

Detailed Description

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic view of the entire interior part for an automobile to which a hook structure for hanging articles according to the present invention is applied, fig. 2 is an enlarged view of the vicinity of a portion a of fig. 1, fig. 3 is a sectional view taken along the direction B of fig. 2, fig. 4 is a sectional view taken along the direction C of fig. 2, and fig. 5 is an enlarged perspective view of the vicinity of a portion a of fig. 1.

The automotive interior part 1 shown in fig. 1 is a side trim of a trunk, which is molded from a resin into a desired shape and is attached to a body panel (not shown) located on a side surface of the trunk, thereby forming an inner side surface of the trunk.

The interior part 1 for an automobile shown in fig. 1 is provided with a pedestal portion 2 as a mechanism for stably disposing a known luggage cover, not shown, which is deployed in a luggage compartment, without rattling. The pedestal portion 2 is formed in a shape extending long in a rail shape along the front-rear direction of the automobile, and in a shape protruding a predetermined amount into the trunk from the decorative surface (specifically, a surface facing the inside of the trunk; hereinafter referred to as "interior decorative surface") of the automobile interior member 1, and the edge portion of the luggage cover developed in the trunk is placed on the upper surface 2A of the pedestal portion, whereby the luggage cover is stably disposed without rattling, and can cover the entire trunk.

In the interior part 1 for an automobile shown in fig. 1, a hook structure 3 for hooking articles (a structure capable of hooking shopping bags and the like) shown in fig. 2 is used.

As an example of assembling the hook structure 3 for hanging things to the interior trim part 1 for an automobile, in the interior trim part 1 for an automobile of fig. 1, the hook structure 3 for hanging things is assembled to the pedestal portion 2 described above. That is, in the automobile interior part 1 of fig. 1, the recessed portion 21 is formed by providing the two steps 2B, 2C on the side surface of the base portion 2 (the recessed portion 21 also constitutes the interior surface of the automobile interior part 1), the opening 4 is opened in the flat surface portion 21A which is the bottom of the recessed portion 21, and the hook 5 is configured to have a shape extending from the inner edge portion of the opening 4, but the configuration is not limited to this. The hook structure 3 for hanging articles in fig. 2 may be assembled to a portion other than the pedestal portion 2 in the entire interior member 1 for vehicle in fig. 1, or the hook structure 3 for hanging articles in fig. 2 may be assembled to an interior member for vehicle other than a side trim of a trunk shown in fig. 1.

Referring to fig. 2 and 5, the hook structure 3 for hanging articles in fig. 2 includes: an opening 4 opened in the interior part 1 for the automobile, and a hook 5 provided at a position slightly protruding outward (specifically, in the direction of the vehicle interior) from the opening 4. The hook 5 is provided at the above position to facilitate hooking of a shopping bag or the like.

The hook 5 includes: a hook portion 50 extending in the width direction of the opening 4; a first support part 51 connected from the hook part 50 to the shape of the inner upper side part 4A of the opening 4; and a second support portion 52 having a shape connected from the hook portion 50 to the inner lower edge portion 4B of the opening 4. In this configuration, the hook portion 50 is supported from the upper and lower side portions 4A and 4B inside the opening 4 by the first and second support portions 51 and 52.

Further, as a specific configuration example of the hook 5, in the automotive interior part 1 of fig. 1, since the rigidity of the entire hook 5 is improved by forming the flange portions 50A and 50B (see fig. 2 and 4) on the back surface edge portions in the vertical direction of the hook portion 50, it is not necessary to adopt, for example, a circular arc portion formed in a large R shape in the vicinity of both side portions in the width direction of the opening 4 or a rigidity reinforcing flange provided in the vicinity of the root portions of the support portions 51 and 52 in order to improve the rigidity of the entire hook 5 in comparison with the conventional measures against the stress generated in the entire hook 5 by the load.

As described above, according to the hook structure 3 for hanging articles in fig. 2, since the hook 5 is configured to support the hook receiving portion 50 by the first and second support portions 51 and 52 as a basic structure, the rigidity of the entire hook 5 against a load can be sufficiently ensured even if the entire hook structure 3 for hanging articles is downsized as compared with the conventional hook in which the hook receiving portion is supported by only one support piece 54 (see fig. 6).

Further, in the hook structure for hanging articles 3 of fig. 2, a longitudinal rib 53 (see fig. 3 and 4) is provided on the back surface of the hook as a means for further improving the rigidity of the entire hook. The vertical rib 53 is formed in a shape that cuts the hook portion 50 and the first and second support portions 51 and 52 in the vertical direction and reaches the vicinity of the inner upper side portion 4A and the inner lower side portion 4B of the opening 4.

Fig. 2 and 4 show an example in which two vertical ribs 53 are provided in parallel, but the present invention is not limited to this example. The number and arrangement intervals of the longitudinal ribs 53 can be appropriately increased or decreased as necessary.

In the hook structure 3 for hanging articles in fig. 2, the two support portions 51 and 52 are formed in a shape that protrudes by a predetermined amount from the interior surface of the automobile interior member 1 toward the inside of the trunk, and the hook portion 50 is configured to be disposed at a position slightly protruding in the direction of the inside of the trunk from the interior surface of the automobile interior member 1 (in the example of fig. 1, "the direction of the inside of the trunk"). This is for facilitating hooking of articles such as shopping bags as described above.

In the hook structure 3 for hanging articles in fig. 2, since the stress generated in the entire hook 5 (the hook portion 50 and the first and second support portions 51 and 52) due to the load is not concentrated at one point but dispersed in the vicinity of the root portions of the first and second support portions 51 and 52, that is, in the vicinity of the inner upper and lower side portions (the vertical direction of the hook 5) of the opening 4, in the structure of the hook 5, it is not necessary to take conventional measures against such stress (for example, forming the entire support portion in a crank shape, forming the vicinity of the both side portions in the width direction of the opening in a large R shape, or the like), and it is possible to set the width and height of the opening 4 to be smaller than the conventional ones, and by this point, it is possible to provide an advantage that the entire hook structure 3 for hanging articles is made compact, and the degree of freedom in design around the hook structure 3 for hanging articles is improved.

Further, in the hook structure 3 for hanging articles of fig. 2, even when the entire structure is downsized, the rigidity of the entire hook with respect to the load can be sufficiently ensured, and therefore, it is not necessary to adopt a conventional measure (addition of another member) for ensuring the rigidity, and by this, it is possible to suitably achieve weight reduction of the entire automobile interior part, reduction in the number of parts, and cost reduction.

In the hook structure 3 for hanging articles in fig. 2, the rigidity of the entire hook 5 is substantially determined by the sectional shape, size, material, and the like of the first and second support portions 50 and 51, and even if the inclination angle (hereinafter referred to as "surface angle") of the hook portion 50 with respect to the flat surface portion 21A on the peripheral edge of the opening 4 is changed, sufficient rigidity can be obtained in the entire hook 5, so that there is an advantage that such a surface angle can be set relatively freely.

The present invention is not limited to the embodiments described above, and a person having ordinary knowledge in the art can make many modifications within the technical idea of the present invention.
