The present invention relates to a hinge for a swing door that can swing-fasten a swing door.

Conventionally, hinges used for swing doors have upper pin means (A) and lower pin means (B) as shown in Figs. It is formed so as to form a small angle opened upwards with one edge of C), the upper pin means (A) has a pair of support elements (D), (D) at symmetrical positions on both sides of the pin (P), In addition, the upper pin means A extends through the opening in the supporting plate E, and the supporting plate E receives a pair of supporting elements D and D, respectively, at symmetrical positions on both sides of the opening. Grooves F are provided, and the door C is always arranged to be forced to a position where the pair of supporting elements D and D are accurately disposed in the grooves F by gravity.

The hinge used in the conventional swing door needs to be fixed at the correct position, and the upper and lower pin means are fixed at the upper and lower positions near the angled portions of the opening. There were many defects.

In addition, when the swing door is opened more than 90 degrees back and forth, it is difficult to configure the swing door to automatically return to its original closed state, and there is a drawback that the swing angle is small.

The present invention is a hinge for a swing door that can be easily and not easily fixed in view of the above-mentioned conventional drawbacks, and can be reliably returned to its original closed state even when the swing door is rotated 90 degrees back and forth. The purpose is to provide.

In order to achieve the above object, the present invention corresponds to a first hinge member having a substantially rectangular-shaped protruding piece in the upper and lower portions of an insertion groove fixed to one of a wall member or a swing door, and corresponding to the first hinge member. A second U-shaped hinge member body having a U-shape attached to one of the swing doors or wall members of the site, and the first protrusion protruding in a substantially U shape from the back surface of the half-opening side of the second hinge member body. A second hinge member having an insertion piece rotatably inserted into the insertion groove of the hinge member and a guide hole formed in the second hinge member body to open into the insertion piece, and in the guide hole of the second hinge member. On both sides of the protruding piece, a fibrous pin secured to be slidably attached, and a rectangular-shaped protruding piece of the first hinge member which pivotally supports the pivoting pin. A shaft is fixed to a portion where the dimension to the front end becomes smaller than the number, and a force is applied so that the pivot pin is always stored in the second hinge member, and the protruding piece of the first hinge member and the second hinge The hinge for a swing door is comprised by the spring which makes the back surface of a member main body contact with a predetermined added force.

The swing door hinge configured as described above has a rectangular shape of the rectangular shape of the first hinge member in which the pivot supporting the pivot pin fixed to the first hinge member and the second hinge member in a state where a force is applied with a spring. Since the protruding piece is fixed to the part where the dimension up to the front end becomes smaller than the dimension up to both sides of the protruding piece, the swing door swings back and forth in a rotation range of less than 90 degrees.

Moreover, since the pivot pin which slides in the guide hole in a 2nd hinge part is used, the 2nd hinge member slides and swings in the axial center direction of a pivot pin at the time of a swing of a swing door.

The hinge member main body 10 and the protruding piece 13 which the front end which protruded on the upper surface of this 1st hinge member main body 10 are flat, and both corner parts 12 and 12 protrude on both sides, The insertion piece 11, 11 formed in this projection piece 13, and this projection piece 13 whose dimension Y from the front end part becomes smaller than the width dimension X of the said projection piece 13 is made. And a fixing fixing hole 14 for fixing and fixing the shaft 5 formed so as to penetrate the insertion grooves 11 and 11 at a portion near the center front end portion of the uppermost portion.

As shown in FIG. 3, the pivot pin 6 is formed of a metal material, one end of which is formed with a through hole 15 through which the shaft 5 penetrates, and the other end has a threaded portion 16 formed therein. It is.

The threaded portion 16 of the pivot pin 6 is screwed into a screw 18 having a spring receiving portion 17 supporting the end of the spring 8.

As shown in FIGS. 8 to 10, the second hinge member 7 includes a second hinge member main body 19 formed in a U shape to sandwich the swing door 1, and the second hinge. Insertion pieces 20 and 20 inserted into the insertion grooves 11 and 11 of the first hinge member 4 integrally formed on the rear surface of the member main body 19 and the pivot pin 6 ), (6) guide holes (21), (21) and insertion holes (22), (22), (22) and (22) of bis etc. formed in the side surface of the second hinge member main body (19). )

In the above configuration, one end of the pivot pins 6 and 6 is inserted into the insertion grooves 11 and 11 of the first hinge member 4 so that the shaft 5 is attached to the fixing hole 14. After passing through the through-holes 15 and 15 of the pivot pins 6 and 6, both ends are caulked to prevent the shaft 5 from escaping from the fixing hole 14.

After such a connection, the fibber pins 6 and 6 are inserted into the guide holes 21 and 21 of the second hinge member 7 to protrude into the second hinge member 7. After inserting the springs (8) and (8) on the pins (6) and (6), the screws (18) and (18) are screwed into the threaded portions (16) and (16). The screws 18 and 18 are locked when any elastic force is applied to the.

The screw 18 or 18 may be locked by a double nut, or may be locked by fastening a set bolt to the screw 18 or 18 in advance.

Since the elastic force is relatively increased, when the swing door 1 is placed at a predetermined angle, the first and second hinge members 4 and 7 are moved on the flat surface by the elastic force of the springs 8 and 8. Return to the original position where it touched.

That is, the swing door 1 is returned to the closed position.

Next, when the swing door 1 is rotated 90 degrees or more forward and backward, as shown in FIG. 12, the elastic force applied to the springs 8 and 8 is applied to the direction in which the swing door 1 is opened. In this state, the swing door 1 is kept open.

Next, another embodiment of the present invention shown in FIGS. 13 to 15 will be described.

In the description of these embodiments, the same components as in the embodiment of the present invention are denoted by the same reference numerals, and redundant description thereof will be omitted.

In the embodiment of Fig. 13, the main difference from the embodiment of the present invention is that the pivot pins 6 and 6 protrude in the first hinge member 4A, and thus are used for the swing door. Even if the hinge 3A is configured, the same effect as that of the embodiment of the present invention can be obtained.

In the embodiment of Figs. 14 and 15, the main difference from the embodiment of the present invention is the three insertion grooves 11, 11 in the protruding pieces 13 of the first hinge member 4B. And inserting pieces 20, 20, 20 inserted into the insertion grooves 11, 11, and 11 of the first hinge member 4B while using the ones formed with the. The hinge hinge 3B is formed by using the second hinge member 7A and three pivot pins 6, 6, and 6 having a) and the hinge for a swing door configured as described above. Even if (3B) is used, the same effect as that of the embodiment of the present invention can be obtained.

Incidentally, in the above embodiment, the first and second hinge members 4 and 7 have been molded from a synthetic resin material. However, the present invention may be molded from any material.

As apparent from the above description, the following effects can be obtained in the present invention.

(One). On both sides of the protruding piece, a shaft for rotatably supporting the fixed pivot pin attached to the first hinge member and the second hinge member in a state of applying a force with a spring is formed on a rectangular protrusion of the first hinge member. Since it is fixed to the part where the dimension up to the front end becomes smaller than the dimension up to, the swing door can swing in a rotation range of less than 90 degrees back and forth.

Therefore, the swinging range of the swing door can be almost doubled than before.

(2). Since the second hinge member and the pivot pin that slides in the guide hole are used, the second hinge member slides and swings in the axial center direction of the pivot pin when the swing door swings.

For this reason, it is possible to reliably prevent dust from entering the first hinge member or the second hinge member.

(3). It is only necessary to fix the first and second hinge members to the wall member and the swing door by vis, etc., so that the first and second hinge members can be fixed by the same operation as when the conventional hinges are fixed and can be easily fixed.

(4). Since the first hinge member and the second hinge member are in contact with the plane in the closed state of the swing door, the swing door can be quickly returned to the closed state by the elastic force of the spring when opening and closing within 90 degrees back and forth.

(5). Since it is possible by adjusting the position of the spring bearing which affixes and fixes the strength of the spring elastic force to a pivot pin, it can be easily adjusted.

(6). Since it is a shape which can shape | mold the 1st, 2nd hinge member with a synthetic resin material, it can manufacture at low cost.

(7). Since the first hinge member, the second hinge member, the pivot pin, the shaft, and the spring are used, the number of parts is small and the structure is simple.
