[Embodiment of the invention]

 In FIG. 1, (A) is a perspective view showing an adhesive molded body 4 according to the present invention, and a back surface side of a hook body adhered to an adherend using the adhesive molded body 4, () Is an explanatory view of a method of manufacturing an adhesive molded article, and (C) is an explanatory view of another method of manufacturing an adhesive molded article. FIG. 2 is a perspective view showing the front side of the hook body.

In FIG. 1 or FIG. 2, reference numeral 1 denotes a hook, and the hook 1 includes a hook body 2, a hook body 3, and a hot melt type adhesive molded body 4.

The main body 2 of the hook is formed of a synthetic resin in the shape of a rectangular flat plate, and its back surface is formed as a mating surface 2B for an adherend such as a wall surface, a pillar, a ceiling, and the like. A rectangular uneven surface area 2A having fine unevenness as a bonding area of the adhesive molded body 4 is provided. The fine unevenness of the uneven surface area 2A is formed at the same time as the processing of the molding die of the hook body 2 and the molding of the hook body 2. Reference numeral 2C denotes a decorative surface formed on the surface of the hook body 2, having a curved surface continuously formed in both sides, and a fitting for fitting the hook body 3 from the upper end to the lower end of the center part in the both sides. A mating groove 2D is formed.

[0013] The hook body 3 is formed of a long metal flat plate, and is formed by bending a front end portion in a U-shape in one direction in the thickness direction and bending a rear end in an L-shape in the other direction in the thickness direction. Is formed in a substantially hook shape. The hook body 3 is formed such that the base of the U-shaped curved portion of the hook body 3 is fitted to the upper end of the fitting groove 2D, and the L-shaped portion at the rear end is the upper end of the hook body 2. The hook body 3 is fitted to the hook body 2 while sliding the hook body 3 downward until the hook body 3 is hooked. A notch 2E is provided at the upper end of the hook body 2 so that the surfaces of the hook body 3 and the hook body 2 are flush with each other.

The adhesive molded body 4 shown in FIG. 1A is formed by molding a hot melt adhesive into a circular plate piece smaller than the size of the mating surface 2 B of the latch body 2. . Various hot melt adhesives such as polyamide-based, polyester-based, and synthetic rubber-based adhesives can be used as the hot-melt adhesive that forms the adhesive molded body 4. Among them, polyolefin-based EVA (ethylene / vinyl acetate copolymer) is used. It has excellent adhesive strength, which is mainly used in the manufacturing process of bookbinding and electric equipment cars, and is not used so much in the field of fasteners. In this embodiment, a polyolefin-based EVA having excellent adhesive strength is used as a hot melt adhesive, which melts at a temperature of 120 to 160 degrees Celsius.

As shown in FIG. 1 (B), the above-mentioned circular plate-shaped adhesive molded body 4 is punched out from a sheet S of hot melt adhesive formed into a sheet using a punching die. Many can be manufactured at a low cost at one time. For the punching die, it is possible to suitably use a cylinder having a size that fits in the palm of the hand. As shown in FIG. 1 (C), a hot melt adhesive in a molten state is poured into the recess 12 of a mold 13 having a circular recess 12 having a shallow bottom to form a circular shape. 4 can be easily and inexpensively manufactured by releasing the mold.

The adhesive molded body 4 is heated and melted on one side by using a lighter, a match, or a special heating tool, and then the melted surface is pressed against the mating surface 2 B of the hook body 2. Since the adhesive molded body 4 can be joined to the hook body 2 by simply attaching it, and the adhesive molded body 4 is in the form of a plate, the molten surface is pressed against the mating surface 2B of the hook body 2 in a short time. It hardens and is firmly joined to the mating surface. In this case, since the adhesive molded body 4 is formed in a plate-like shape smaller than the size of the mating surface 2B of the hook body 2, no skill is required, and anyone can set a predetermined position on the mating surface 2B. Can be easily and quickly joined. Then, as shown in the example of the drawing, the uneven surface area 2A is formed on the mating surface 2B, and the molten surface of the adhesive molded body 4 is pressed against the uneven surface area 2A to be cured. Since a large bonding area with the mating surface 2B is ensured, the adhesive molded body 4 can be firmly joined to the mating surface 2B. The operation of joining the adhesive molded body 4 to the mating surface 2B may be performed by a factory worker before shipment, or may be performed by a user at the time of use.

Next, a description will be given of a method of attaching the hook 1 formed by bonding the adhesive molded body 4 to the mating surface 2B of the hook body 2.

First, as shown in FIG. 3, a flame such as a lighter 5 or a match is applied to the adhesive molded body 4 and the adhesive molded body 4 is heated and melted. Etc. to the adherend 6 (see FIG. 4). In this way, the adhesive molded body 4 spreads thinly between the uneven surface area 2A of the joining surface 2B and the adherend 6, the molten portion thereof is rapidly cooled and hardened, and the hook 1 is covered. Affixed to the body 6. A frame or the like may be directly hooked on the hook body 3 of the hook 1 attached and attached to the adherend 6 in this manner, or the shelf 8 may be attached to the hook 1 as shown in FIG. The shelf 8 may be used by placing an object on it.

The adhesive molded body 4 that has been heated and melted is almost in a liquid state in a slime state. However, since the adhesive molded product 4 is a hot melt adhesive and the hot melt adhesive has a viscosity, the adhesive molded product 4 does not fall from the uneven surface area 2A. In addition, it is desirable to strongly press the adhesive molded body 4 when bonding is required in a short time because the temperature decreases more quickly when the adhesive molded body 4 is strongly pressed and spread thinly.

When the hook 1 stuck to the adherend 6 has been peeled off in some way, or when it is desired to change the position of the hook 1, the hook body 2 and the hook When a flathead screwdriver is inserted into the gap with the adherend 6 and moved so as to separate them, the adhesive molded body 4 is peeled from the adherend 6. Therefore, by repeating the above procedure again, the hook 1 can be attached to the adherend 6.

In the hook 1 of the present invention, an adhesive molded body 4 is joined to the back surface of a hook body 2 having a hook body for hooking an object, and the adhesive molded body 4 is melted to be covered. Since it is to be adhered to the body 6, the hook 1 can be firmly attached to the body 6 even if there is some unevenness on the body 6 side. In other words, since the adhesive molded body 4 in a molten state is adhered to the adherend 6, the molten portion of the adhesive molded body 4 enters the irregularities of the adherend 6 to reliably capture the irregularities of the adherend 6. It can be said that it is more desirable that the adherend 6 has many concaves and convexes.
