Next, the embodiments related to the present invention will be explained using drawings.

Fig. 1 shows a one-touch mounting hinge H (hereinafter, it may only be referred to as hinge H). The hinge H is a component that rotatably couples the second member D to the first member B among the two members B and D (refer to Figure 11, etc.) to be joined. The hinge H has a single-touch operation The hinge body 1 is mounted on the first member B, and the hinge plate 2 is mounted on the second member D with a special structure.

The hinge H includes a hinge main body 1, a hinge plate 2 and a hinge pin 3. The hinge body 1 is installed on the side B11 of the first member B of the two members B and D to be joined such as the cabinet and the door leaf, and has a cylindrical hinge pin penetration portion 11. The hinge plate 2 is mounted on the side portion D1 of the second member D of the two members B and D to be combined, and has a cylindrical hinge pin penetration portion 221. The hinge pin 3 penetrates through the respective hinge pin penetration portions 11 and 221 of the hinge body 1 and the hinge plate 2 to connect the hinge body 1 and the hinge plate 2.

The hinge body 1 is provided with: a pair of first and second mounting flanges 16 formed on the upper and lower ends of the fixing surface 101 facing the side portion B11 of the first member B; and fasteners 17 mounted on the Between a pair of first mounting flanges 16 and second mounting flanges 16 (refer to Figure 1). The first and second mounting flanges 16 can be embedded in a pair of first and second mounting holes 41, 41 (refer to Figures 11 and 12) formed on the side portion B11 of the first member B, and are formed separately It is a convex shape, and in the convex shape, at least the side edges close to the upper and lower ends of the fixing surface 101 respectively have concave grooves 160.

The fastener 17 has a first end and a second end. The first end is locked on one of the pair of mounting flanges 16, such as the groove 160 of the first mounting flange 16, and is capable of being circumscribed to the first mounting protrusion. The periphery of the rim 16 is slightly U-shaped, and the second end is locked to the other of the pair of mounting flanges 16, such as the recess of the second mounting flange 16, in a reverse direction compared to the first end. The groove 160 has a U-shape that can be circumscribed around the second mounting flange 16.

The hinge body 1 is integrally formed by zinc die-casting or other metal materials as a whole. As shown in Fig. 3, its horizontal section is a slightly angular U-shape, and is formed in an elongated manner in the vertical direction. When the hinge main body 1 is attached to the first member B, the front surface portion arranged on the front side of the first member B extends from the fixing surface 101 to be longer than the opposite back surface portion. A pair of upper and lower hinge pin penetration portions 11 (11U, 11D) are formed in a cylindrical shape with a predetermined length up and down in the axial direction at the upper and lower portions of the front end side edge portion of the elongated front portion. The space between the upper hinge pin penetration portion 11U and the lower hinge pin penetration portion 11D becomes a groove-shaped gap portion 12 for communicating with the hinge pin penetration portion 221 of the hinge plate 2 described later.

In addition, in the hinge body 1, a slightly angular U-shaped groove 13 is formed on the outer surface of the front part, and one end of the groove is positioned at the axial middle part of the outer peripheral surface of the upper hinge pin penetration portion 11U (more axially The direction center is slightly offset from the predetermined position of the gap 12), and the other end is located at the predetermined position of the axial middle portion (slightly offset from the gap 12) of the outer peripheral surface of the lower hinge pin penetration portion 11D. Except for a part of the groove 13, the remaining part is formed to be narrow and deep, and each hinge pin penetration portion 11 is recessed to form an opening from the outer peripheral surface to the inner peripheral surface. Furthermore, in the groove 13, a part of the upper and lower groove portions 131 extending at right angles to the axial direction of each hinge pin penetration portion 11, and a middle groove extending parallel to the axial direction of each hinge pin penetration portion 11 Each part near the upper and lower ends of the part 132 is formed slightly wider. In that width In the wide part, a pair of protruding pieces 14 are formed upright on the extension lines of each of the upper and lower groove parts 131 with a narrow width. Between the pair of protruding pieces 14, groove portions 131 communicating with the upper and lower groove portions 131 are collectively formed.

A hinge pin stopper 15 is installed in the slightly angular U-shaped groove 13. The hinge pin stopper 15 shown in FIG. 4 is an element for engaging and holding the hinge pin 3 described later in the hinge pin penetration portion 11. The hinge pin stopper 15 is composed of a metal wire.

(4) Since the fastener 17 is made of metal wire, its manufacture is easy.

(5) Because the fastener 17 is formed into a slightly S-shaped or a slightly S-shaped composite shape with a wave in the middle part as a whole, it can be made into a shape that is easy to install between a pair of mounting flanges 16 but not easy to fall off.

(6) Since the hinge plate 2 can be integrally formed by a metal material, it is easy to manufacture and easy to install on the second member D.

(7) The hinge plate 2 is formed by two plate bodies joined at right angles due to the mounting plate 21, and the mounting block 22 is formed in a substantially columnar shape in the two-sided mounting plate at right angles, and the fixing pin penetration portion 222 is formed by The two-sided joints of the mounting plate 21 at a right angle are formed in the mounting block 22 in such a way that the simple shape of the hinge plate 2 allows the mounting hole 42 to be made into a simple shape, so that the hinge plate 2 can be easily installed in the mounting hole 42.

(8) Since the mounting hole 42 of the second member D is formed in the corner of the side D1 of the second member D in accordance with the shape of the mounting block 22 of the hinge plate 2, the mounting hole 42 can be made into a simple shape , Making the processing of the mounting hole 42 in the second member D easy.

(9) Since the fixing pin 23 is made of a slightly L-shaped metal rod that can penetrate through the fixing pin penetration portion 222 of the hinge plate 2, it can be easily manufactured by its simple shape and can be easily installed on the hinge plate Piece 2.

In addition, in this embodiment, although each mounting flange 16 of the hinge body 1 is formed into a square shape, and each mounting hole 41 of the first member B is matched with the shape of each mounting flange 16 of the hinge body 1, The side portion B11 of the first member B is formed in a square shape, but the mounting flanges of the hinge body can also be rounded, and the mounting holes 41 of the first member B can be matched with the shape of the mounting flanges of the hinge body. The side B11 of the first member B is formed in a circular shape.
