Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double door structure for improving the engagement between a door stop and a lock.

[0002]

2. Description of the Related Art Generally, a double-sided gate is provided with a lock and a drop lock of a handle portion on a vertical frame on the meeting side, and a door-stop member is attached to an expected surface of the vertical frame.

When the lock of the handle portion is a lock with a built-in frame such as a cylinder lock, the latch has a structure of protruding and retracting from the expected surface of the vertical frame. The operating part of the lock is provided below the projected surface of the vertical frame. Therefore, in a gate provided with this kind of lock, a latch or a latch receiving opening is formed in the upper part of the expected surface of the vertical frame, and a drop lock opening is formed in the lower part with different sizes. Correspondingly, an opening for exposing the latch or the latch receiver to the outside and an operating opening for vertically operating the operating portion of the lock are also provided on the door-stop member attached to the above-mentioned prospective surface. Has been formed.

However, in addition to inward opening and outward opening, there are right-handed and left-handed methods of opening the gate, and the direction of protrusion of the latch (whether it comes out from the right or the left) and the direction are different depending on the type. The location of the door is also different. Further, since the drop lock is usually attached only to the gate to which the latch receiver is attached, the position of the drop lock is different.

Therefore, in the gate, an opening for latch lock and an opening for drop lock are formed on the prospective surface of the vertical frame.
It is necessary to prepare two types of doors having only the opening for the latch lock formed, but manufacturing the two types of gates poses problems in terms of cost and construction. Therefore, normally, two openings are formed on the prospective surface of the gate regardless of the presence or absence of a drop lock, and the opening not attached to the drop lock is closed by a door stop member attached to the prospective surface. Has been adopted.

[0006]

However, in this method, although the gate can be simplified, in the door-stopping material, openings having different sizes are formed vertically and those having only the latch lock opening are formed. One set of two types is required. In addition, since the door contact material, which has two openings or only one opening, is not formed vertically symmetrically, it cannot be used by changing the top and bottom in correspondence with the opening of the gate. Also,
Since there are two types of door contact materials, it is not possible to simply switch the left and right sides and the front and back sides according to the left / right direction of the gate.

As described above, even if the gate is common, it is necessary to prepare various kinds of door contact materials corresponding to each opening method, which results in high manufacturing cost and
It was very troublesome because a predetermined material had to be selected from a large number of door stop materials at the time of construction.

It is an object of the present invention to solve the above problems and to provide a double-open gate structure capable of improving the versatility of the door contact material with respect to the method of opening the gate, reducing the cost, and improving the workability. It is an issue.

[0009]

In order to solve the above-mentioned problems, in a double-opening gate structure according to the present invention, a lock door provided with a latch and a receiving door provided with a latch receiver are provided so that they can be opened.
And it is characterized by having a lock on either one of the gates and having the following requirements. (B) The above latch and latch receiver shall be provided in the area other than the prospective surface of the vertical frame of the gate (b) Mounting to attach the lock to the prospective surface of the longitudinal frame of both gates in the vertical frame Only the opening for use is formed, and the mounting opening is formed at the longitudinal center of the prospective surface (C) A doorstop is attached to the prospective surface of the vertical frame of one of the gates. (D) The door stop member has an opening that is aligned with the mounting opening.

The opening of the vertical frame to which the lock is not attached is preferably closed with a closing material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1, 2 and 3 show a double-opening gate (inward-opening / right-handed type), in which a pair of gate posts 1 are suspended by hinge fittings 2 so that the respective gates 3 can be opened. Has been done. The gate 3 is formed by vertically assembling the upper and lower horizontal frames 4 and the left and right vertical frames 5 and arranging the horizontal rails 6 inside thereof. One of the gates 3 is a lock door 3a provided with a latch, The other is a receiving door 3b provided with a latch receiver. In addition, a lock 7 is placed on the vertical frame 5 on the side opposite to the hanging side of one gate 3.
Is attached. The reference numeral 21 designates a suspension cover, which covers the gap between the column 1 and the vertical frame 5.

The above-mentioned lock is a known push-pull lock. As shown in FIG. 4, inside the vertical frame 5 (on the site side) and on the outside (outside the site) on the lock door 3a side, the inside pedestal 8a and the outside pedestal are provided. 8b and the receiving door 3
Strike pedestal 9a from the site side and outside of the vertical frame 5 on the b side
And a fixed pedestal 9b are coupled to each other, and a latch 10 is provided on the inside pedestal 8a.
0 is operated to engage / disengage the latch receiver 11 of the strike pedestal 9a, thereby locking and unlocking.

The latch 10 is formed in a block shape, and a part of the latch 10 projects outward from the inside pedestal 8a and rotates laterally. The projecting portion has a right-angled triangular cross section. ing. And latch 1
0 is normally projected and locked to the latch receiver 11, and is formed so as to be laterally rotatable by pushing or pulling the handle portion 12 of the inside pedestal 8a or the outside pedestal 8b and to be released from the latch receiver 11. There is. Latch 1
0 is configured so that the direction of the protrusion can be changed by switching the top and bottom inside the pedestal 8a.

Next, only the mounting opening 14 for mounting the drop lock 7 in the vertical frame 5 is formed on the prospective surface 13 of the vertical frame 5 on the side opposite to the suspension base of the gates 3 on both sides. The opening 14 is formed in the longitudinal center of the prospective surface 13. The lock 7 is attached to one of the gates 3. Drop lock 7
As shown in FIG. 5, the lock body 7a is inserted into the vertical frame 5 through the opening 14, the lock body 7a is screwed to the periphery of the opening, and the drop rod operating portion 15 (see FIG. 4) is attached to the opening 14. )
Is located.

A door contact member 16 as shown in FIG. 6 (a) is attached on the prospective surface 13 of the vertical frame 5 of the lock door 3a or the receiving door 3b. The door contact member 16 is formed by bending one side edge of the elongated plate member and attaching an elastic body to the door contact member 16a.
The opening 17 is formed in the center of the longitudinal direction so as to be aligned with the mounting opening 14 of the prospective surface 13.

When the receiving door 3b is not provided with the door-stop member 16, the latch 10 slides on the prospective surface 13 of the vertical frame 5 of the receiving door 3b when the lock door 3a is opened and closed, thereby causing damage. Since there is a risk of attachment, it is preferable to attach a scratch prevention plate 18 (see FIG. 4) to the prospective surface 13.

When the door stop member 16 is attached to the entrance surface 13, the screw receiver 22 shown in FIG. 6 (a) is inserted into the central recessed groove (existing groove) 24 of the entrance surface 13, and the door contact member 16 is inserted. The screw 23 inserted from the outside is screwed into the screw receiver 22.
Since the screw receiver 22 rotates by being screwed, it is engaged with the groove 24 as shown in FIG. 12, and the door-stop member 16 is pulled by the screw receiver 22 and fixed by screwing.

By the way, the opening 17 of the vertical frame 5 of the gate 3 to which the lock 7 is not attached is closed by the closing member 19. The closing member 19 is made of a synthetic resin, and has a convex portion 20 that fits into the openings 14 and 17 of the vertical frame 5 or the door stop member 16. When the door stop member 16 is attached to the vertical frame 5, as shown in FIG. 6 (a), the opening 17 of the door stop member 16 is closed from the inside by the closing member 19, and the door stop member 16 is attached to the vertical frame 5. When it is not attached, the opening 17 of the vertical frame 5 may be directly closed by the closing member 19 as shown in FIG.

Next, an assembling mode of the double-opening gate having the double-opening gate structure will be described for each system of opening and closing.

(A) Inward-opening / Right-handed method This is the same as the example in FIG. 1 (see FIG. 3), and as shown in FIG. 7, the gate (lock door) on the right side when viewed from the outside (outside the site). 3a) opens inside (site side), and a lock 7 is arranged on the left gate (reception door 3b). An inside pedestal 8a and an outside pedestal 8b are arranged on the vertical frame 5 of the lock door 3a, and a strike pedestal 9a and a fixed pedestal 9b are arranged on the vertical frame 5 of the receiving door 3b. Then, the door stop member 16 is attached to the prospective surface 13 of the vertical frame 5 of the receiving door 3b. A closing member 19 is attached to the opening 17 of the door-stop member 16 of the lock door 3a as shown in FIG. 6 (b).

(B) Inward-opening / left-handed system As shown in FIG. 8, the gate (lock door 3a) on the left side when viewed from the outside opens inward, and the lock 7 on the right gate (receiving door 3b) opens. Are placed. Inside pedestal 8a is attached to the vertical frame 5 of the lock door 3a.
The outside pedestal 8b and the strike pedestal 9a and the fixed pedestal 9b are arranged on the vertical frame 5 of the receiving door 3b. Then, the door stop member 16 is attached to the prospective surface 13 of the vertical frame 5 of the receiving door 3b. A closing member 19 is attached to the opening 17 of the vertical frame 5 of the lock door 3a as shown in FIG. 6 (b). In addition, the above-mentioned each pedestal is the same as above (a) upside down,
You can switch to the left and right gates 3. Further, the same door contact member 16 as in (a) above may be mounted upside down.

(C) In the case of the outside opening / right-handed method As shown in FIG. 9, the gate (lock door 3a) on the right side when viewed from the outside (outside the site) opens to the outside (gate 3b) on the left side. The lock 7 is arranged. An inside pedestal 8a and an outside pedestal 8b are arranged on the vertical frame 5 of the lock door 3a, and a strike pedestal 9a and a fixed pedestal 9b are arranged on the vertical frame 5 of the receiving door 3b. The door stop member 16 is attached to the prospective surface 13 of the vertical frame 5 of the lock door 3a. The opening 1 of the vertical frame 5 of the receiving door 3b
As shown in FIG. 6 (a), a blocking member 19 is attached to 7.
The same pedestals as those in (a) above may be attached, and the latch 10 may be replaced in the inside pedestal 8a to change the direction of the protrusion. In addition, the door contact material 16 is the above
The same thing as (a) can be installed upside down and the inside out.

(D) In the case of the outside opening / left-handed type, as shown in FIG. 10, the gate (lock door 3a) on the left side when viewed from the outside
Open outward, and lock 7 on the right gate (receiving door 3b).
Is arranged. Inside pedestal 8 is attached to the vertical frame 5 of the lock door 3a.
a and an outside pedestal 8b, and a strike pedestal 9a and a fixed pedestal 9b are arranged on the vertical frame 5 of the receiving door 3b. The door stop member 16 is attached to the prospective surface 13 of the vertical frame 5 of the lock door 3a. A closing member 19 is attached to the opening 17 of the vertical frame 5 of the receiving door 3b as shown in FIG. 6 (a). In addition, the above-mentioned each pedestal is the same as above (a) upside down,
It suffices to replace the right and left gates, and further replace the latch 10 inside the inside pedestal 8a to change the direction of the protruding portion.
Further, the same door contact member 16 as in (a) above may be attached by reversing the inside and outside.

As described above, the gate 3 is opened and is common regardless of the type of hand, and the base of one set of locks is turned upside down,
By simply replacing the latch 10, it becomes a lock door and also a receiving door.

Further, since the openings 14 and 17 are formed in the central portions of the frame prospective surface 13 and the door contact member 16, even if the door contact member 16 is turned upside down or upside down, the opening of the vertical frame 5 is opened. 14
Can be matched to. Therefore, since it is possible to open with a single door contact member 16 and cope with the difference in the hand, the material cost can be reduced and the workability of assembling the gate 3 can be improved.

When the inward opening method (see, for example, FIG. 3) is changed to the outward opening method, the hinge fitting 2 may be used upside down as shown in FIG.

Although the above-mentioned example is an example in which the gate 3 is provided with a push-pull lock, the present invention is not a system in which the latch 10 and the latch receiver 11 are built in the vertical frame 5 of the gate 3, but a vertical frame 5.
What is necessary is just to be what is provided in the site | part except the prospective surface 13. Therefore, for example, as shown in FIG. 11, when the handle type handle portion 12 of the lock door 3a is rotated, the latch = latch 10 is rotated and the latch receiver 11 of the receiving door 3b is rotated.
It may be a double-sided gate with an inner lock that engages with.
In the figure, the same reference numerals as those in the above-mentioned example indicate the same parts, and an opening (not shown) is formed at the center of the frame prospective surface 13 and the door contact member 16. Therefore, also in this example, since it is possible to open with a single door-stop member and cope with the difference in handiness, it is possible to obtain the effect that the material cost can be reduced and the workability of assembling the gate can be improved. it can.
