[Gate configuration]
As shown in FIG. 1, the gate A has two gates 1 and 2 pivoted between left and right pillars b and c in a double door configuration.
Door (hereinafter referred to as the "left door") 1 is rotatably supported on a pillar (hereinafter referred to as the "left pillar") b via a hinge b1 having an upper and lower axis, and door (hereinafter referred to as the "right door") 2 is rotatably supported on a pillar (hereinafter referred to as the "right pillar") c via a hinge c1 having an upper and lower axis.
The right door 2 is provided with a drop rod b2 at its lower end side that can move up and down freely. By lowering this drop rod b2 and inserting it into a rod holder b3 provided on the ground g, the right door 2 is fixed so that it cannot be opened, and by raising the drop rod b2 and removing it from the rod holder b3, the right door 2 can be opened or closed.

The left door 1 and the right door 2 are provided with handles 3 and 4, as shown in FIGS.
As shown in Figure 2, the handle (hereinafter referred to as the "rotating handle") 3 of the left door 1 is arranged on the front facing surface 10a (hereinafter referred to as the "front side") of the right vertical frame 1a of the left door 1 facing the road, and on the rear facing surface 11a (hereinafter referred to as the "rear side") of the house facing the front facing surface 10a.
The rotating handles 3 are coaxial and rotatably supported on an axis parallel to the thickness direction of the left door 1, and are used to engage and disengage the hanging device 5 for engaging the left door 1 with the right door 2 and to open and close the left door 1.
The handle 4 of the right door 2 (hereinafter referred to as the "fixed handle") is disposed on a front surface 20a and a rear surface 21a of the left vertical frame 2a of the right door 2, as shown in FIG.
The fixed handles 4 are fixed immovably at positions symmetrical in the front-rear direction with respect to the right door 2 and at the same height position, and are used to open and close the right door 2.

A hanging device 5 is provided on the left door 1 so as to be freely movable from the right projecting surface 12a of the right vertical frame 1a of the left door 1 by rotating the rotating handle 3, and a receiving device 6 to which the hanging device 5 can be engaged and disengaged is provided on the left projecting surface 22a of the left vertical frame 2a of the right door 2.
In addition, the right vertical frame 1a of the left door 1 incorporates a metal front plate (hereinafter referred to as the "left metal front plate") 7 on which the hanging device 5 is supported, and a case 8 incorporating a rotation transmission mechanism e that transmits the rotation of the rotating handle 3 as rotation of the hanging device 5.
An insertion opening 10b is provided on the right projecting surface 12a of the right vertical frame 1a of the left door 1 for inserting the left metal front panel 7 and case 8 into the right vertical frame 1a, and with the left metal front panel 7 and case 8 inserted, they are screwed to the right projecting surface 12a of the right vertical frame 1a of the left door 1.

[Hanging device configuration]
The hanger 5 is made of metal, and as shown in Figures 4(a) and 5(a), has a plate-shaped main body 5a, protrusions 5b protruding in the front-to-rear direction from both the front and rear sides of the tip side (right end side) of the main body 5a, and a hanger gear e1 which is part of the rotation transmission mechanism e and is provided on the left end side of the main body 5a, and the main body 5a is rotatably supported on the left metal front panel 7 via a support shaft 5c having an axis parallel to the thickness direction of the left door 1.
As shown in Figures 3 and 5, the main body 5a of the hanging device 5 is rotatably supported on the left metal front panel 7 within the right vertical frame 1a of the left door 1, and rotates in response to the rotation of the rotating handle 3. This rotation causes the protrusion 5b to appear and disappear from the right visible surface 12a of the right vertical frame 1a of the left door 1 and to move forward and backward relative to the receiving device 6.
In addition, the protrusion 5b may be provided protruding from only one of the front or rear side surfaces of the main body portion, and the protrusion 5b protrudes in a direction to engage with the receiving device 6 from at least one of the front or rear side surfaces of the main body portion 5a.

[Configuration of the receiver]
As shown in FIGS. 3 to 5, the receiving device 6 is opened in a right metal front panel 6a fixed to the left projecting surface 22a of the left vertical frame 2a of the right door 2.
The receiving device 6 is opened on the surface facing the right projecting surface 12a of the right vertical frame 1a of the left door 1, and is formed so as to embrace the protruding portion 5b of the hanging device 5.
The receiving device 6 is made of metal and is bent so that the entire circumference of the back side (right side) of the inner edge protrudes to the right, and the front and rear ends of the bent part on the inner edge side serve as engagement portions 60a with which the protrusion 5b of the hanging device 5 engages, and the upper end serves as an abutment portion 61a with which the main body of the hanging device 5 abuts.

As shown in FIG. 3B, the receiver 6 has an engagement/disengagement opening 62a on the lower side and a holding opening 63a on the upper side.
The engagement/disengagement opening 62a is for the rotating hanging device 5 to be engaged and disengaged, and also serves as the starting end side when engaging.
The holding opening 63a holds the engaged hanger 5 and is the terminal end side when engaged.
As shown in FIG. 3B, the engagement/disengagement opening 62a is formed in a substantially rectangular shape with a width that allows at least the hanging tool 5 together with the protruding portion 5b to pass therethrough.
As shown in FIG. 3B, the holding opening 63a is narrower than the front-rear width of the engaging/disengaging opening 62a, and is formed in a substantially rectangular shape so that the protrusion 5b cannot be removed but the main body 5a can pass through.
In this type of receiving device 6, the engagement/disengagement opening 62a and the holding opening 63a are connected in the vertical direction, and the holding opening 63a is formed in an approximately convex shape in which the engagement/disengagement opening 62a is connected to the center of the upper end of the engagement/disengagement opening 62a via a narrowed portion 64a that narrows toward the upward direction.
The inner peripheral edge of the receiver 6 is provided with a cushioning material 65 a made of a hard synthetic resin material so as to conform to the approximate convex shape of the receiver 6 .
The cushioning material 65a has the function of reducing the impact and reducing the contact noise when the hanger 5 comes into contact with the engagement portion 60a or the abutment portion 61a of the receiving device 6 when engaging or disengaging the hanger 5, and when the left door 1 and right door 2 in the engaged state move in the opening/closing direction due to a gust of wind.
Furthermore, the cushioning material 65a abuts against the front and rear side surfaces of the main body portion 5a that engage with the holding opening 63a, thereby holding the hanging tool 5 without rattling.

[Configuration for Engaging and Disengaging the Hanger with the Receiver]
As shown in Figs. 3 to 5(a), when the hanger 5 is engaged with the receiver 6, it locks the left door 1 and the right door 2 together to keep them closed (locked state).
In the locked state, as shown in Figures 3(a) and 5(a), the main body 5a including the protrusion 5b of the hanger 5 penetrates the receiver 6, a portion of the upper side of the main body 5a is engaged and held by being clamped between the abutment portion 61a, and the protrusion 5b is located in a position spaced away to the right from the engagement portion 60a of the receiver 6.
In addition, in this locked state, as shown in FIG. 4(b), when a gust of wind causes the left door 1 and the right door 2 to move in the opening direction and the left door 1 and the right door 2 are bent at an angle between them, causing the hanger 5 to come off the receiver 6, the protrusion 5b comes into contact with the engagement portion 60a, thereby preventing the hanger 5 from coming off and also stopping the opening movement of the left door 1 and the right door 2.

When the left door 1 and the right door 2 are to be changed from a locked state to an unlocked state in which they can be opened, the rotating handle 3 is rotated in the opening direction (counterclockwise in the drawing) as shown in FIG. 5(b).
At this time, the rotation of the rotating handle 3 in the unlocking direction is transmitted from the rotation transmission mechanism e to the hanging device 5, and the hanging device 5 rotates in the unlocking direction (clockwise in the drawing).
When the hanger 5 rotates in the unlocking direction (counterclockwise in the drawing), the main body 5a passes downward through the holding opening 63a and moves to the engagement/release opening 62a, and the protrusion 5b also passes through the engagement/release opening 62a and is stored inside the left door 1, thereby entering the unlocked state.

To lock the left door 1 and the right door 2 again, the rotating handle 3 is rotated in the locking direction (clockwise in the drawing).
At this time, the rotation of the rotating handle 3 in the locking direction is transmitted from the rotation transmission mechanism e to the hanging device 5, and the hanging device 5 rotates in the locking direction (counterclockwise in the drawing).
When the hanging device 5 rotates in the unlocking direction (counterclockwise in the drawing), the main body 5a together with the protrusion 5b comes out from the right projecting surface 12a of the right vertical frame 1a of the left door 1, and the protrusion 5b and then the main body 5a are inserted into the receiving device 6 through the engagement/disengagement opening 62a, and the main body 5a engages with the retention opening 63a, thereby entering the locked state.
When the hanging device 5 is rotated and inserted into the receiving device 6, as shown in FIG. 3(b), even if the left door 1 and the right door 2 are slightly misaligned in the opening/closing direction, the upper end of the main body 5a abuts against the narrowed portion 64a and is guided by the inclined surface of the narrowed portion 64a to the retaining portion 63a, thereby enabling the door to be locked.

[Configuration of the left metal front panel]
The left metal front panel 7 is attached to a right end portion 8a of a case 8 built into the right vertical frame 1a of the left door 1, as shown in FIGS. 2(b), 3, 4(a) and 5.
The left metal front panel 7 has a projection panel portion 7a which is fixed to the right projection surface 12a of the right vertical frame 1a of the left door 1, a front panel portion 7b which continues from the projection panel portion 7a to the front side, and a rear panel portion 7c which continues from the projection panel portion 7a to the rear side.
The projection plate portion 7a is sized to cover the insertion opening 10b provided on the right projection surface 12a of the right vertical frame 1a of the left door 1, and is screwed to the right projection surface 12a.
The projection plate portion 7a has an opening 7d through which the hanging device 5 appears and disappears.
A support shaft 5c is suspended across the front plate portion 7b and the rear plate portion 7c, and the hanging device 5 is supported on this support shaft 5c so as to rotate integrally therewith, and the hanging device 5 is adapted to rotate freely in and out of the opening 7d in the left metal front plate 7.
As shown in FIG. 4, the support shaft 5c passes through the case 8, and the left metal front panel 7 and the case 8 are integrated by this support shaft 5c.

[Case configuration]
The case 8 includes a case body 80 and a cover portion 81, which are molded from a synthetic resin material.
As shown in Figure 5, the case body 80 is provided with a fixing plate 8b for fixing it to the right projecting surface 12a of the right vertical frame 1a of the left door 1, and is held within the right vertical frame 1a by screwing this fixing plate 8b to the right projecting surface 12a of the right vertical frame 1a.
The fixing plate 8b is arranged so as to overlap the projection plate portion 7a of the left metal front panel 7, and is screwed together with the projection plate portion 7a.
The case 8 has a left metal front panel 7 integral with the outside of the case main body 80, and the case main body 80 houses a part of the main body 5a, the rotating shaft 10 of the rotating handle 3, and a rotation transmission mechanism e including a hanger gear e1, and the case main body 80 is covered with a cover part 81 to form a single unit.
Since the case 8 is a unit that integrates the left metal front panel 7 and the various components mentioned above, the installation work for the right vertical frame 1a of the left door 1 can be easily performed.

[Configuration of rotation transmission mechanism]
As shown in Figure 5, the rotation transmission mechanism e comprises a hanger gear e1 provided on the hanger 5 and a handle gear e2 supported on the rotation shaft 10 of the rotating handle 3 so as to rotate coaxially and integrally with the hanger gear e1 and the handle gear e2 are arranged to mesh with each other and move in conjunction with each other.
The hanger gear e1 and the handle gear e2 are both arc-shaped with a number of teeth corresponding to the amount of rotation of the hanger 5, which allows the rotation transmission mechanism e to be miniaturized and the case 8 to be made compact.
The handle gear e2 has rotation-limiting recesses e4 and e5 provided around the rotating plate e3 surrounding the center of rotation, and as the rotating plate e3 rotates between the locked and unlocked states, a hemispherical fitting portion s1 is pressed against the periphery of the rotating plate e3 by a spring s, fitting into the recess e4 to maintain the locked state, and fitting into the recess e5 to maintain the unlocked state.
When the rotating handle 3 rotates, the fitting portion s1 escapes from the recesses e4 and e5 against the pressing force of the spring s, causing the rotating plate e3 to rotate and the handle gear e2 to rotate.
Such a rotation transmission mechanism e transmits the rotation of the rotating handle 3 from the rotating shaft 10 via the hanger gear e1 and the handle gear e2 as the rotation of the support shaft 5c, and the hanger 5 can be rotated by the rotation of this support shaft 5c.

[Modifications of the hanging tool and receiving part]
As shown in Figs. 6 and 7, the gate A of the present invention may also be provided with a hanging device 5' having a deadbolt lock structure.
A hanger 5' in this modified example includes a prismatic main body 5a and a protrusion 5b protruding from the front side surface on the right end side of the main body 5a.
The hanging device 5' is supported so as to move linearly to the left and right with respect to the left metal front panel 7.
The deadbolt lock structure is a well-known structure in which the rotation of the rotating handle 3 moves the hanging device 5' in a linear direction to the left and right to engage with the receiving device 6', and a well-known transmission mechanism (not shown) is built into the case 8 to transmit the rotation of the rotating handle 3 as a linear movement of the hanging device 5'.

As shown in Figures 6 and 7, the receiving device 6' is formed in a rectangular shape of a size that allows the hanging device 5', which moves in a straight line through the opening shape of the right metal front panel 6a, to be engaged and disengaged together with the protrusion 5b, and a box-shaped body 6b is provided on the inside of the left vertical frame 2a of the right door 2 in which the hanging device 5' is housed when engaged.
As shown in Figures 6 and 7, the front inner surface of the box-shaped body 6b has an arc-shaped engagement portion 60b formed so as to be concave toward the front, and the protrusion 5b abuts against this engagement portion 60b to prevent the hanging device 5' from coming loose.

Such a hanger 5 ′ and receiving portion 6 ′ can be used for normal locking and unlocking by rotating the rotary handle 3 .
In addition, when a gust of wind causes the left door 1 and the right door 2 to move in the opening direction and form an angle between the left door 1 and the right door 2 to bend and the hanger 5' tries to come off the right metal front plate 6a of the receiver 6', the protrusion 5b comes into contact with the engaging portion 60b with the arcuate surface, thereby preventing the hanger 5' from coming off and also stopping the opening movement of the left door 1 and the right door 2.

The gate A with the above configuration allows the left door 1 and the right door 2 to be tightly closed without rattling, and also has a good exterior design.

In the above-described embodiment, the gate A has a left door 1 and a right door 2 arranged in a double door configuration, but the gate A may also be a single door having either the left door 1 or the right door 2 (not shown).
In this case, by erecting a support pillar on the opposite side of the hinge b1 that supports the door so that it can be opened and closed freely, and providing receivers 6, 6' on this support pillar, it is possible to obtain the same effect as when a door has a left door 1 and a right door 2 that open like a double door.

The gate of the embodiment of the present invention has been described in detail above with reference to the drawings, but the specific configuration is not limited to these embodiments, and the present invention includes design changes that do not deviate from the gist of the present invention.

Furthermore, the above-mentioned embodiments can be combined by reusing each other's technologies, so long as there are no particular contradictions or problems in their purpose and configuration, etc.
