[Problem that the idea aims to solve]

With the conventional hinges mentioned above, positioning can be done properly, and you can use both hands to fasten the screws. There are advantages to using it. However, with this hinge, there is no attachment piece to the box body and door. A protruding pin is provided in each plane. This protruding pin is installed on the metal plate. It is installed upright by welding to the attachment piece. Therefore, a pin shaft is required in addition to the mounting piece. However, this welding work is time-consuming. Also, when welding, the protrusion of the pin If the installation position shifts even slightly, the temporary fixing hole on the door or box body will not match up. There is a disadvantage that proper positioning (temporary fixing) cannot be performed. Also, complete the temporary fixing state. Even if the worker can use both hands to completely fix the screws, it is difficult to attach screws to a simple through-hole. The work of inserting the screw into the door plate (box body plate) and securing it properly is to Requires skill. In particular, when screwing in a screw, it is necessary to make one or two turns when the screw is first screwed in. It is determined whether proper screwing is performed or not, and if the screwing is initially done at an angle, If the screws are inserted, there is a risk that the door will not close properly with respect to the box body.

0004 In addition, in recent years, the door is usually kept in a closed state with respect to the box body. A magnetic catch is provided on the box body side, and the door side is compatible with a magnetic catch. Install a magnetic adsorption plate (flat metal plate) to prevent the door from opening against your will. It has become. Therefore, in addition to the hinge that connects the door and the box body, there is a A magnetic catch and a magnetic adsorption plate are required to hold the magnet. There are disadvantages such as the time-consuming work of positioning and installing the cut catch and magnetic adsorption plate. It was.

[0005] This idea solves the above problems and allows for proper positioning of the door and box body. A hinge that can be easily and accurately determined and installed, and that can keep the door closed. The purpose is to provide.

【Example】

FIG. 1 is a perspective view showing a specific embodiment of the hinge according to this invention.

[0011] The hinge has two mounting pieces, one for the box body 4 and one for the door 5. It consists of a pin shaft 3 that rotatably connects the pieces 2 and 1. The attachment piece 2 to the box body 4 has its tip wound around the pin shaft 3 so that it can rotate freely. The flat pin shaft mounting portion 22 and the base end of the pin shaft mounting portion 22 are arranged upward at right angles. A flat vertical piece 23 is formed by bending, and the upper end of this vertical piece 23 is horizontally It consists of a substantially disk-shaped attachment portion 21 that is bent at right angles to the direction. Also, the door The attachment piece 1 to 5 is a flat pin whose tip is wound freely around the pin shaft 3. Bend the shaft attachment part 12 and the base end of this pin shaft attachment part 12 downward at right angles. It consists of a substantially disk-shaped mounting portion 11 formed therein.

0012 The feature of the hinge described in claim 1 (claim 1) of the utility model registration is that the above-mentioned mounting The parts 21 and 11 are inserted into the temporary fixing holes 41 formed in the box body 4 and the door 5, respectively. , 51, and is formed to a size that allows a tight fit. In the example, The mounting parts 21 and 11 are both formed into a substantially disk shape having a constant thickness. Temporary fixing holes 41, 5 with approximately the same diameter, size, and depth as the mounting portions 21, 11 of 1 are formed on the door 5 and the box body 4. Therefore, these attachment parts 21, 11 are fitted into the temporary fixing holes 41 and 51, respectively, and the upper parts of the mounting parts 21 and 11 The surfaces are substantially flush with the upper surfaces of the openings of the temporary fixing holes 41 and 51. In addition, in the plane of both the mounting parts 21 and 11, there are holes 41 for temporary fixing, that is, holes 41 for temporary fixing. , 51 with the mounting parts 21 and 11 tightly fitted, respectively, with the screws 25 and 14. To ensure complete attachment, screw holes (female threads) 24 and 13 for screwing are opened. be. Screws 25 and 14 are screwed into the screw holes 24 and 13 in advance.

[0013] A hinge with this type of configuration is used for knocks on record racks, color boxes, etc. Down products (box body and door are separate, sold separately, hinges included) It is considered a component and is used for products in which the purchaser assembles unit products at home. To attach (assemble) the door to the box body 4 using this hinge, see Figure 2. As shown, fit the mounting part 21 into the temporary fixing hole 41 of the box body 4, and then install it. By fitting the part 11 into the temporary fixing hole 51 of the door 5, it can be attached to the door 5 and the box body 4. The hinge is temporarily fixed firmly. This ensures proper positioning between the door 5 and the box body 4. The positioning can be done, and the proper positioning state can be firmly and temporarily fixed. Therefore, completely fixed When performing work (screw fastening work), not only the door and box body but also the hinge (both sides are attached) There is no need to hold pieces 1 and 2). The worker uses both free hands to complete the Can perform all fixing work (screw fixing work). In addition, both mounting parts 21 and 11 have There are screw holes 13 and 24 for screwing in screws, and screws 14 and 25 are screwed in, respectively. It has been deployed. Therefore, even if the worker is inexperienced with screw-inserting work, The screws 14 and 25 are guided by the female screws 13 and 24, and the screws are screwed in the correct state. It can be fixed accurately to the door 5 and the box body 4. In this way, both the mounting parts 21 and 11 themselves are tightly fitted into the temporary fixing holes 41 and 51. Because of this, there is no need for separate protruding pins and pin welding work as in the past. It is not a tool, but a precise alignment between a minute protruding pin and a small temporary hole, and the shape The construction work can be eliminated. In addition, both mounting parts 21 and 11 have in-plane screw screws. Since the holes (female threads) 13 and 24 are provided, when temporarily fixing with screws, it is difficult to tighten the screws. Just screw it into the screw hole, even an amateur can avoid the disadvantages of screwing in the screw diagonally. This enables proper fixing work to be carried out.

[0014] Furthermore, the hinge described in claim 2 of the utility model registration claim (claim 2) is substantially the same configuration as that of the embodiment described in claim 1 (claim 1) It is something that you have. Therefore, a detailed explanation of the overall configuration will be omitted. The feature of this hinge is that the pin of the mounting piece 2 to the box body 4 is fixed as shown in Figure 1. The upper surface of the shaft attachment part 22 is the magnet surface 22a, and the pin shaft of the attachment piece 1 is attached to the door 5. The point is that the part 12 is a magnetic adsorption plate (metal plate part). In other words, the pin shaft mounting portion 22 and the pin shaft attachment part 12 are those that come into contact with each other when the door 5 is closed. (See Figure 2). In the embodiment, when the door is closed, the magnet surface 22a becomes a magnetic adsorption plate. 12 is set to magnetically attract.

[0015] With a hinge having such a configuration, as shown in FIG. , the magnet surface 22a is in contact with the pin shaft mounting part (made of metal) 12, and the shaft mounting part 1 2 is magnetically attracted by the magnet surface 22a, and the closed state of the door 5 is maintained by attraction. Therefore, The hinge itself can maintain the closed state of the door 5, and unlike conventional Not only does it eliminate the need for a suction plate, but it also eliminates the troublesome positioning of magnetic catches, etc. And installation work can be completely eliminated. In addition, in the embodiment, an example was shown in which the pin shaft attachment part 22 was the magnet surface 22a, but In this case, the entire mounting piece 1 to the door 5 should be a magnetic surface, and the mounting piece 1 to the box body should be If 2 is made of metal, the pin shaft mounting part 12 and the pin shaft mounting part 2 will be connected as shown in FIG. 3, as well as the vertical piece 23 and the door attachment part 11 are magnetically attracted to each other, increasing the attraction area. Furthermore, the force for holding the door closed can be further strengthened.

[0016]

[Effect of the idea]

The hinge described in claim 1 (Claim 1) of the utility model registration of this invention has two sides. When the attachment part itself is tightly fitted into the temporary fixing hole provided on the door and box body, In both cases, we decided to open a female screw hole in the plane of both mounting parts to insert the screw. , the proper positioning state can be temporarily fixed, and screw fixing work can be performed properly and easily. . Therefore, protruding pins and pin welding work are not required as in the past; Precise positioning work between protruding minute protruding pins and temporary fixing holes becomes unnecessary. In addition, in the hinge described in the second claim of utility model registration (Claim 2), the box The pin shaft mounting part of the mounting piece to the main body is a magnetic surface, and the pin shaft mounting part of the door mounting piece Since it is made into a magnetic adsorption plate part, both pin shaft mounting parts that come into contact when the door is closed are magnetically adsorbed. and keep the door closed. Therefore, in addition to the conventional hinge, the magnetic Instead of eliminating the need for catch and magnetic adsorption plate, Macnet catch and magnetic adsorption plate are used. It is an excellent product that achieves the purpose of the invention, such as eliminating all disadvantages such as proper positioning work. have an effect.
