The hinge main body 1 is attached to one member, and the hinge blade 2 is attached to the other member. Each member has a special structure that can be attached with one touch.

As shown in FIG. 2, the flange body 1 is convex so as to be fitted into a pair of mounting holes formed on both ends of the fixed surface 101 facing the side of one member and on both ends of the side of one member. A pair of mounting flanges 16 formed in a shape and having concave grooves 160 at edges close to both ends of at least the fixed surface 101 of the convex shape, and one end thereof are locked to one of the concave grooves 160 of the pair of mounting flanges 16. The other mounting flange 16 is circumscribed around one mounting flange 16 and has a substantially U-shape, and the other end is locked to the other concave groove 160 of the pair of mounting flanges 16 in the direction reversed from one end. It is circumscribed and has a substantially U-shape around the flange, and is provided with a clip 17 (see FIG. 1) that is hung between the mounting flanges 16.

In this case, as shown in FIG. 3, the hinge body 1 is integrally formed of zinc die cast or other metal material, and the horizontal cross section is substantially U-shaped and long vertically (this hinge body 1). One side portion arranged on the front side when attached to the member is formed longer than the other side portion, and hinge pin insertion portions 11 (11U, 11D) are shafts at the upper part and the lower part of the tip edge portion thereof, respectively. It is formed in a cylindrical shape having a predetermined length with the direction facing up and down, and each of the upper and lower hinge pin insertion portions 11 is a groove-shaped intermittent portion 12 so as to be able to communicate with the hinge pin insertion portion 221 of the hinge blade 2 described later. .. Further, the hinge main body 1 has a predetermined position on the outer side surface of one side portion, one end of which is an axial intermediate portion (slightly closer to the intermittent portion 12 than the axial center) of the outer peripheral surface of the pin insertion portion 11U above. The other end is taken at a predetermined position on the axial middle portion (slightly closer to the intermittent portion 12 than the axial center) on the outer peripheral surface of the lower pin insertion portion 11D, and the groove 13 is formed in a substantially U shape. To. The groove 13 is narrow and relatively deep except for a part, and is opened by cutting out from the outer peripheral surface to the inner peripheral surface at the position of each hinge pin insertion portion 11. Further, in the groove 13, a part of each groove 131 on both sides extending at right angles to the axial direction of each hinge pin insertion portion 11 and near both ends of the intermediate groove 132 extending in parallel with the axial direction of each hinge pin insertion portion 11. A portion is formed to be slightly wider, and a pair of projecting pieces 14 are formed so as to rise along the extension of each of the narrow grooves 131 on both sides in this wide portion, and each of the narrow sections on both sides is formed between the projecting pieces 14. A groove 131 communicating with the groove 131 is also formed. A hinge pin stopper 15 is attached to the substantially U-shaped groove 13. As shown in FIG. 4, the hinge pin stopper 15 is for engaging with the hinge pin 3 described later in the hinge pin insertion portion 11 to hold the hinge pin 3, and is made of a metal wire rod, in this case, a stainless steel wire rod. The hinge body 1 is bent into a substantially U-shape so as to be fitted into a substantially U-shaped groove 13 (including a groove 131 between each pair of projecting pieces 14). As shown in FIG. 6, such a hinge pin stopper 15 is fitted into a substantially U-shaped groove 13 (including a groove 131 between each pair of projecting pieces 14) of the hinge body 1, and each pair of projecting pieces 14 is fitted. It is crimped and fixed, and a part of both sides of the hinge pin stopper 15 is passed in a string shape in the inner peripheral surface of each hinge pin insertion portion 11 at the position of each hinge pin insertion portion 11.
In the hinge main body 1, the fixed surface 101 facing the side portion of one member is an outer surface of the intermediate portion between both side portions of the hinge main body 1, and a pair in the center in the left-right direction near both upper and lower ends of the fixed surface 101. The mounting flange 16 is projected. In this case, each mounting flange 16 is formed on the fixed surface 101 in a square shape, here protruding in the shape of a rectangular plate slightly long in the vertical direction, and is intermediate in the thickness direction of the entire peripheral edge of each mounting flange 16 (in this case, in this case). A concave groove 160 is formed in a square cross section (center in the thickness direction).

There are two types of clips 17. As shown in FIG. 5A, one clip 17A is made of a metal wire, in this case a stainless steel wire, is formed in a substantially S shape as a whole, and one end of the pair of mounting flanges 16. It is locked to the concave groove 160 so that it can be externally attached to the periphery of one mounting flange 16 in a substantially U shape, and the other end is locked to the other concave groove 160 of the pair of mounting flanges 16 in the direction reversed from one end. The other mounting flange 16 is formed in a substantially U-shape so as to be externally external to each other. As shown in FIG. 5B, the other clip 17B is also made of stainless steel wire, which is substantially S-shaped as a whole and has a corrugated composite shape in the middle portion, and one end is attached to a pair. Locked to one concave groove 160 of the flange 16 so that it can be externally attached to the periphery of one mounting flange 16 in a substantially U shape, with the other end inverted from one end and the other concave groove of the pair of mounting flanges 16. It is locked to 160 and is formed in a substantially U-shape so as to be externally accessible around the other mounting flange 160. In this case, both ends of the clips 17A and 17B are formed in a substantially U-shape, but they may be formed in a substantially U-shape instead of the substantially U-shape. Thus, as shown in FIG. 6, each clip 17 is formed so as to be able to be hung between the mounting flanges 16 of the hinge main body 1.

The hinge body 1 has such a configuration, and each mounting hole of one member is formed in a square shape on the side portion of one member in accordance with the shape of each mounting flange 16 of the hinge body 1.

In this way, in the hinge main body 1, each mounting flange 16 is fitted into each mounting hole formed on the side portion of one member from one surface side of the side portion toward the other surface side, and each of these mountings is performed. A clip 17 is hung on the other side between the mounting flanges 16 passed from the hole to the other side of the side of one member, and the hinge body 1 is fixed to the side of one member with one touch. It is supposed to be done.

As shown in FIG. 7, the hinge blade 2 has a mounting plate 21 having a plane larger than the mounting holes formed on the side of the other member corresponding to the pair of mounting holes of the one member, and the mounting plate 21. The entire peripheral edge of this plane is left as a flange portion 211 and is projected in a block shape so as to be fitted into the mounting hole of the other member. It includes a mounting block 22 having a 222 and a fixing pin 23 (see FIG. 9) that is inserted into the fixing pin insertion portion 212 and engaged with the peripheral edge of the mounting hole of the other member.

In this case, as shown in FIG. 8, the hinge blade 2 is formed integrally with a zinc die cast or other metal material, and is formed in the shape of two vertically long rectangular plates to which the mounting plates 21 are joined at right angles. The height of the mounting block 22 is substantially the same as the length (height) of the intermittent portion 12 of the hinge body 1 so that the flange portion 211 having a constant width is left on the entire peripheral edge of the two surfaces in the two right-angled surfaces of the mounting plate 21. It is formed in a substantially rectangular shape at a slightly lower position, and the fixing pin insertion portion 222 penetrates from the upper surface to the lower surface of the mounting block 22 along the corner portion close to the right-angled two-sided joint portion of the mounting plate 21 of the mounting block 22. The hinge pin insertion portion 221 is formed so as to penetrate from the upper surface to the lower surface of the mounting block 22 along the opposite corner portion, and the half portion of the mounting block 22 on the hinge pin insertion portion 221 side is an intermittent portion of the hinge body 1. The hinge pin insertion portion 221 of the mounting block 22 is formed so as to be able to be fitted to the 12 and to be communicable with the upper and lower hinge pin insertion portions 11 of the hinge main body 1. The corners of the mounting block 22 on the hinge pin insertion portion 221 side are rounded at a predetermined angle.
Further, as shown in FIG. 9, the fixing pin 23 is made of a substantially L-shaped metal rod that can penetrate the fixing pin insertion hole 222 of the hinge blade 2. In this case, the fixing pin 23 is made of stainless steel or other metal bar (round bar), and is formed into an L shape as a whole by bending, and has a length that allows it to penetrate the fixing pin insertion portion 222 of the mounting block 22. It has a long shaft portion 231 having a shaft portion 231 and a short shaft portion 232 bent in a direction perpendicular to the long shaft portion 231 and having a length shorter than that of the long shaft portion 231. In this case, the tip of the long shaft portion 231 is formed in a tapered shape whose diameter is gradually increased from the tip toward the short shaft 232 side.

The hinge blade 2 has such a configuration, and a mounting hole for the other member is formed at a corner portion on the side of the other member in accordance with the shape of the mounting block 22 for the hinge blade 2.

In this way, the hinge blade 2 is fitted with the mounting block 22 in the mounting hole formed on the side of the other member from one side of the side toward the other side, and the other side. The fixing pin 23 is passed through the fixing pin insertion portion 222 of the mounting block 22 on the other surface side of the mounting block 22, and the flange portion 211 is brought into contact with the peripheral edge portion of the mounting hole on one surface side of the other member and fixed. The pin 23 is engaged with and fixed to the peripheral edge of the mounting hole on the other surface side of the other member.

The hinge pin 3 is composed of two pins 3A and 3B, each of which is made of stainless steel or other metal bar (round bar), and as shown in FIG. 10, substantially the entire hinge body 1 is connected to the hinge pin insertion portion 11. It is formed into a linear shape having a length substantially the same as or slightly longer than the length that can be inserted up to half of each hinge pin insertion portion 221 of the hinge blade 2. The tips of the pins 3A and 3B are formed in a tapered shape whose diameter is gradually increased from the tip to the rear end. Hinge on the outer peripheral surface of each pin 3A, 3B when the tip side of each pin 3A, 3B is inserted from one end of the insertion side of each hinge pin insertion portion 11 above and below the hinge body 1 to the other end of the intermittent portion 12 side. Predetermined positions on the tip side corresponding to the hinge pin stoppers 15 passed through the upper and lower hinge pin insertion portions 11 of the main body 1, and the pins 3A and 3B are from the upper and lower hinge pin insertion portions 11 of the hinge main body 1 to the hinge blades 3. When approximately half of the hinge pin insertion portion 221 is inserted, the intermediate portion corresponding to the hinge pin stopper 15 passed through each of the upper and lower hinge pin insertion portions 11 of the hinge body 1 can be engaged with the hinge pin stopper 15 at a predetermined position. Locking grooves 31 and 32 are provided together with the locking guides 311 and 321. In this case, the locking groove 31 at a predetermined position on the tip side is for making each pin 3A and 3B stand by in each of the upper and lower hinge pin insertion portions 11 of the hinge body 1, and is on the tip side of the outer peripheral surface of the pins 3A and 3B. A hinge pin stopper 15 is formed at a predetermined position with a small diameter so that it can be fitted, and a portion adjacent to the rear end side of the locking groove 31 is formed in a tapered shape in which the diameter is gradually increased from the locking groove 31. A locking guide 311 is provided adjacent to the rear end side of the locking groove 31. The locking groove 32 at a predetermined position in the intermediate portion is for locking the pins 3A and 3B passed between the hinge main body 1 and the hinge pin insertion portions 11 and 221 of the hinge blade 2, and the pins 3A and 3B. The hinge pin stopper 15 is provided with a small diameter formed at a predetermined position in the middle portion of the outer peripheral surface of the outer peripheral surface so that the hinge pin stopper 15 can be fitted, and the portion adjacent to the tip end side of the locking groove 32 is gradually expanded from the locking groove 32 in a tapered shape. A locking guide 321 is provided adjacent to the tip end side of the locking groove 32. The rear ends of the pins 3A and 3B are formed in a flange shape with a small diameter portion, that is, a groove 33, formed slightly ahead of the rear ends.

Thus, the pins 3A and 3B forming the hinge pin 3 are attached to the side portion of one member from the upper and lower hinge pin insertion portions 11 of the hinge body 1 to the hinge pin insertion portion 221 of the hinge blade 2 attached to the side portion of the other member. The hinge body 1 and the hinge blade 2 are connected to each other by being inserted so that the other member is rotatably connected to one member.
