Description

[Detailed Description of the Invention] The present invention relates to an improvement of a plastic hanging device for hanging clothes and other articles, such as a coat hanger installed in a vehicle interior.

Considering a coat hanger as a typical example of an article hanging device, this type of coat hanger is of course a functional device with a hook for hanging clothes, but at the same time, it also has an excellent appearance that does not spoil the atmosphere of the interior of a car, etc. It must also be a decorative part with a

However, in conventional coat hangers of this kind, tapping screws have been used exclusively because the coat hanger itself must be firmly fixed. For this reason, not only is the installation workability poor, but the head of the screw is often visible, spoiling the appearance of the screw, and in other cases, separate parts or complicated configurations are required to hide the head of the screw.
Of course, this problem can be avoided if the hook is attached directly to the wall using double-sided tape, but then the adhesion is too weak to be of any practical use.

This proposal was developed from this perspective, and aims to provide a plastic item hanging tool that is easy to install, has a good appearance, and has strong adhesion as a coat hanger etc. that can be attached to the wall surface of a vehicle interior. It is.

Hereinafter, a preferred embodiment of the present invention will be described in detail as a coat hanger in a vehicle interior with reference to the accompanying drawings.

This coat hanger, as shown in Figures 1 and 2,
It consists of a hook member 10 having a hook 2 for hanging clothes or the like on a part of the outer surface of the main body 1, and a rivet or fastener member 20 for attaching the hook member 10 to a wall surface, as shown in FIGS. 3 and 4. All are integrally molded plastic products.

The hook member 10 is a so-called external appearance component that must have a good appearance, and the shape of the main body 1 and the hook 2, the hook installation position, etc. are determined exclusively according to design requirements, but in this embodiment, the hook 2 is literally It has a hook shape, and its base flows from the top surface of the main body 1 to the other side, and the main body 1 itself has a thick block shape. Alternatively, the hook 2 may be seen as growing on one side of the block-shaped main body 1 whose bottom surface 3 is approximately rectangular.

The main body 1 is provided with a drive pin 4 having a rectangular cross section that extends beyond the bottom surface 3, and the interior of the main body 1 is a hollow portion 5 that opens to the bottom surface 3. 5 It is shaped like a pillar sticking out from inside. Further, a check piece 6 protruding radially inward is provided on the peripheral edge of the hollow portion 5 near the opening, in this case, the peripheral edge located below the hook 2.
is provided, and its axial inner surface 7 (FIG. 5) serves as a non-return surface for the fastener member. The functions of these pins, hollow portions, and non-return surfaces will be described later in connection with the fastener member 20.

The fastener member 20 consists of a head 11 and a shank 12 extending from the lower surface of the head, and in this embodiment, both the head and the shank have a rectangular cross-section.
From the head 11 to the shank 12, a pin insertion hole 13 is bored in the interior thereof into which a drive pin 4 of the hook member is inserted in the axial direction. In addition, the shank 12 has a plurality of incisions made from the tip (lower end), and in this case, four expandable diameter portions 14 each having a rectangular shape with each side being an outer surface due to diagonal cuts and having a substantially triangular shape when viewed from the bottom. ...is being formed.

The inner surface of the pin insertion hole 13 in which this diameter-expandable portion 14 is located is reduced in diameter in the radial direction, and as described later, when the pin 4 is inserted, this diameter-reduced portion 1
3' is forcibly expanded and the diameter expandable portion 14
... expands outward in the radial direction.

Furthermore, the head 11 is provided with a non-return surface 15 which engages complementarily with the non-return surface 7 of the hook member mentioned above; in this embodiment, in order to create this surface 15, the head 11 is axially into two parts 11a, 1
1b, the end portion 11a has a large diameter, and a radial step is provided between the two portions 11a and 11b.

The process of attaching this coat hanger to the wall P will be explained below, but the wall P in this example is assumed to be the interior wall of a vehicle, and a foam material P _f is placed on the innermost steel plate P _i . It has a three-layer structure, on which a decorative sheet P _d is placed and a decorative sheet P d is attached.

The shank 12 of the fastener member 20 is attached to the wall surface P.
A mounting hole H is drilled into which the fastener member 20,
Furthermore, it also functions to prevent hook 2 from rotating.

First, the shank 12 of the fastener member 20 is inserted into the mounting hole H drilled in the wall P, and the lower surface of the head 11 is placed on the wall surface. Next, the hook member 10
facing this fastener member, and inserting the drive pin 4 into the pin insertion hole 13 of the fastener member.

This work naturally involves the worker pressing the hook member 10 toward the wall surface, but at the beginning of the work, the drive pin 4 has not yet reached the reduced diameter portion 13' of the pin insertion hole 13. The pin 4 can be pushed in smoothly with relatively light resistance, but when the pin 4 begins to penetrate into the reduced diameter portion 13', it will encounter relatively strong resistance. If the force is continued to be pushed in against this resistance, the expandable diameter portion 14 of the shank 12 will begin to expand radially outward, and eventually the bottom surface 3 of the hook member 10 will come into contact with the wall surface P, and the fastener When the pressing of the hook member is completed until it is substantially flush with the lower surface of the member head 11, as shown in FIG. is sufficiently expanded in diameter on the back side of the iron plate P _i and is secured to the back edge of the mounting hole.

At the same time, as also shown in FIG. 6, the head 11 of the fastener member 20 is housed in the hollow part 5 of the hook member 10 and is hidden from the outside, and is provided on the periphery of the hollow part 5. During the above-mentioned installation work, the check piece 6 rides over the large diameter portion 11a on the end side of the fastener member head 11 and settles on the stepped surface with the small diameter portion 11b.

That is, since the non-return surface 7 on the hook member side and the complementary non-return surface 15 on the fastener member side come into contact with each other in the direction in which the hook member comes off and exhibit a non-return function, the hook member will easily fall off from now on. Without a problem,
It can withstand the weight of clothing well.

However, when renovating the wall itself or repairing some structure behind the wall, the wall P
There may be cases where it is necessary to remove the main coat hanger attached to the Therefore, in this proposal, in consideration of such a case, a window 8 is opened in the wall surface of the main body 1 of the hook member 10 at a position where the check piece 6 can be seen, as shown by the imaginary line in FIG. Insert a tool 30 such as a screwdriver through this window 8, pry up the non-return engaging piece 6, and release the engagement between the complementary non-return surfaces 7 and 15. The pin 4 can be pulled out by pulling the hook member 10.

In addition, the non-return surfaces 7 facing oppositely to each other in the axial direction,
15 may be formed in any form, for example, a protrusion and a groove, or may be formed in the shape of a check piece as shown in the figure, by providing this check piece on the head 11 of the fastener member. A recess (for example, when the window 8 is opened, the opening edge of the window 8 itself) may be formed on the side thereof.

Furthermore, as mentioned above, in this embodiment, the hook 2 of the hook member 10 is hook-shaped, so the hook member must be installed so that the hook 2 faces a predetermined direction (generally upward). That is, although the hook member itself has directionality, as in this embodiment, the wall mounting hole H and the fastener member shank 1
2. Fastener member head 11 and hook member hollow part 5
If they are rectangular shapes that fit exactly into each other, it will be extremely easy to attach the hook member with directionality.

On the other hand, if the hook 2 does not depend on the rotational position of the hook member, such as a button type, the mounting hole H, shank 12,
The head 11 and the hollow portion 5 do not need to have a non-circular cross-sectional shape, and may be circular.

Regarding the order of assembly, in the previous explanation, the fastener member was first inserted into the wall mounting hole, and then the pin 4 of the hook member was inserted into the insertion hole 13 of the fastener member. Temporarily assemble the hook member and fastener member in advance by inserting them until the pin 4 does not reach the reduced diameter portion 13' of the insertion hole 13, and then attach the shank of the fastener member to the wall. The pin 4 may be inserted into the hole and then pushed in by pressing the hook member.

In addition, as illustrated in this example, the wall surface P to which this coat hanger is attached is the foam material layer P.
If the layer has a property of elastic compression deformation, such as _f ,
During the above installation process, the main coat hanger part becomes recessed compared to its surroundings, that is, its thickness becomes thinner, so the expandable diameter part 14 of the fastener member expands in diameter and is at a position where it locks onto the back edge of the mounting hole. The distance between the fastener member and the lower surface of the head of the fastener member should be designed in accordance with the wall thickness when it becomes thinner.

However, if the expandable diameter portion 14 of the fastener member is configured to expand toward the tip, as in this embodiment, considerable plate thickness tolerance can be expected. The possibility of elastic compressive force on the wall surface P is also advantageous for this type of fastener function. After the installation is completed as shown in Figure 6, the layer P _f tries to return to its original thickness and generates a force that tries to push up the lower surface of the head of the fastener member, and this force ends up on the opposite side. This is because the force that presses the expandable portion 14 more strongly against the edge of the mounting hole transfers and closes, continuing to strengthen the fixing force.

Furthermore, in this proposal, the object of improvement is a hanging device for an article that faces a wall surface, has an up-down direction when in use, and receives loads in the earth's axis direction, like the hook member in this embodiment. The stopper piece 6 is located at the upper part of the periphery of the main body 1 along the earth's axis direction under use. In this way, when a load is applied to the hook 2 in the earth's axis direction, the non-return surface 7 of the non-return piece 6 comes into stronger contact with the complementary non-return surface 15 of the fastener member, and this load can best withstand.

Furthermore, if a window is provided on the wall surface of the hook member through which the check piece 6 can be accessed so that it can be removed, it is advantageous and rational to be able to reuse the fastener member 20. To this end, it is desirable that the diameter-expandable member 14 has good hinge characteristics that will not tear even if it is changed several times between the normal state and the diameter-expanded state. Therefore, in this embodiment as well, as shown in FIG.
Ribs 16 are provided that extend in the axial direction from the base toward the head opening and protrude radially inward to increase the rigidity of the parts other than the part that can be expanded in diameter, and to define the hinge part at the end of the ribs. ing.

In any case, as detailed above, according to the present invention, the two-part structure makes installation work convenient, and not only can sufficient adhesion force be expected, but it also allows for a good-looking article hanging without exposing the fastener members involved in adhesion. A fastener is obtained.
