2. Description of the Related Art A folding door as shown in FIG. 1 is sometimes used between a bathroom and a dressing room. This folding door accommodates a folding door D formed by connecting the left and right doors d1 and d2 via a connecting member 5 in a foldable and deployable manner in a frame F attached to an entrance, and when pushing the connecting portion h toward the bathroom. Is the vertical frame 8 on the hanging side
The slide hinges 102 provided at the upper and lower ends of 2 are folded and opened by moving along the rails formed on the upper frame 1 and the lower frame 2, and the slides are pulled by pulling the connecting part toward the changing room. The hinge can be deployed and closed by moving it in the opposite direction along the rail, and a latch lock L is used to hold it closed.

The old-type latch locking device was one in which the latch head was simply biased so as to project downward from the lower rail. However, when the bathroom floor, dressing room floor, and lower rail are designed to be on the same plane, and the barrier is free, the tip of the latch head contacts the floor when the folding door is opened. There is a risk of damage to the latch head or scratches on the floor.
Only when the folding door is closed, the latch head protrudes below the lower rail, and when the folding door starts to open, the latch head is retracted above the lower rail to prevent the latch head from being damaged and to prevent the bathroom floor surface. A latch lock device for a folding door that does not damage
It was disclosed in the publication.

In this prior art, a mounting member fixed to the first door, a movable body which is always urged upward by the first urging member with respect to the mounting member, and a movable body which can be lifted and lowered to the lower end portion thereof. A latch unit, which is housed in the second head and is always urged downward by the second urging member, and a driven cam which is attached to the lower end of the movable body and has an obliquely upward cam surface at one end, Drive having an oblique downward cam surface corresponding to the upward oblique cam surface of the driven cam of the latch unit

The vertical frame of the door is mounted so that the cam surfaces of the two cams face and contact each other when the folding door is closed. Thus, when the folding door is closed, the cam surface of the drive cam pushes down the cam surface of the driven cam of the movable body of the latch unit to lower the movable body,
Therefore, the latch head, which has been located above the lower rail until then, is moved to a position lower than the lower rail.

[0005]

However, in the above-mentioned prior art, the driven cam is attached to the door- side vertical frame of the first door , and the drive cam is attached to the door- side vertical frame of the second door. Therefore, in order for the cam surfaces of both cams to reliably contact and act when the folding door is closed, both the driven cam and the drive cam must be formed in a cantilever shape. Then, driven mosquitoes at the time of closure of the Orito
The cam always receives pressure from the drive cam on only one side. Therefore, the driven cam and the drive cam may be deteriorated by mechanical fatigue and damaged during long-term use. Driven cam and drive
In order to reduce the deterioration by using a cam that is as short as possible, it is necessary to make the cross-sectional area of the connecting material as small as possible. This leads to a decrease in connection strength. Also, subordinate
If there is an error in the mounting position of either the moving cam or the drive cam , the cam surfaces of both cams cannot work together, and there is a possibility that the door may not be locked when the folding door is closed. Further, in the case of the above-mentioned prior art, it is necessary to perform machining on the door-end vertical frame of the first door and the door-vertical frame of the second door having different shapes and sizes for attaching the latch unit and for attaching the drive cam. Therefore, the processing and management of the frame material is complicated.

The present invention has been made in view of the above points, and its object is to constantly urge the latch head downward.

As shown in FIGS. 3 and 10, the actuating member AM, which is another component of the latch lock device of the present invention, abuts on the lower end faces of the vertical frames 91 and 92 on the connecting member side of the doors d1 and d2. Thus, as an example, the shaft portions 91a, 92 of the vertical frames 91, 92 are
fixing part 25 fixed by a screw 24 screwed into a
And a drive cam 26 standing upright from the upper surface of the fixed portion and having an obliquely downward cam surface. The fixed part 25 is a vertical frame 91
, 9 2 shaft portions 91 a, 92 a corresponding to the ring portion 27.
Has a shaft 24 that penetrates the screw 24 through the ring
It is designed to be screwed into a and 92a. 28 is a stopper integrally formed with the actuating member AM.
When M is attached to the vertical frames 91 and 92, it projects from the bathroom side of the vertical frame, and when the folding door D is fully opened (that is, when folded), it hits the inner wall of the bathroom and the vertical frame 91
, 92 to prevent a collision with the inner wall surface of the bathroom.
29 in FIG. 10 is a fin for ensuring watertightness,
One end is continuous with one end of a similar fin mounted on the lower frame of each door.

In order to mount the above-mentioned actuating member AM on the vertical frames 91, 92, the notches 9 are formed on the surfaces of the lower ends of the vertical frames facing each other.
b is formed. Then, with the drive cam 26 of the actuating member AM fitted and inserted in the notch 9b from below and protruding from the notch 9b in the other vertical frame direction, as described above, the fixing portion 25 is provided with the vertical frame 91. Abutting on the lower end surface of
The screw 24 penetrates the ring portion 27 and further the shaft portion 9 of the vertical frame.
It is attached by screwing into 1a and 92a.

Next, the operation of the above configuration will be described. When the folding door D is in the non-closed state, as shown in FIGS. 12 and 13, the driven cam 1 of the movable body 12 of the latch unit LU is shown.
Since the pressing force from the drive cam 26 of the actuating member AM is not received by 23, as shown in FIGS.
The movable body 12 is moved upward by the first biasing member 16,
Therefore, the latch head 13 is held above the lower rail 2a provided on the lower frame 2. Further, the latch head 13 can be adjusted via the adjusting screw 19 and the adjusting case 14 so as to be able to move upward by 3 mm at the maximum with respect to the lower end surface of the latch unit LU.

Next, when the folding door D is in the closed state, the drive cam 26 of the actuating member AM is moved to the latch unit LU immediately before the closing of the folding door D.
As the movable body 12 comes into contact with the driven cam 123 and moves to the completely closed position, the movable body 12 is pressed downward against the first biasing member 16. Therefore, the latch head 13 is moved below the lower rail 2a, but since the latch head 13 is elastically urged downward by the second urging member 17, the latch head 13 is temporarily urged when it contacts the lower rail 2a. Since it is retracted upwards, the latch head 13 can cross the lower rail 2a, and when the folding door is moved to the fully closed position as shown in FIGS. 11 (b), 14 and 15, the second Since the latch head 13 is again urged downward by the urging member 17 and protrudes downward from the lower rail 2a and engages with it, the folding door is maintained in the closed state.

When opening the closed folding door,
The latch head 13 that is moved toward the bathroom has the lower rail 2a.
By the force received from the second urging member 17, the second urging member 17 is moved upward to be disengaged from the lower rail 2a. Also, as shown in FIG. 13, the vertical frame 91 on the connecting member side of each door d1, d2
, 92 are separated from the connecting member 5 to drive the actuating member AM.
The moving cam 26 is a follower of the movable body 12 of the latch unit LU.
In order to release the frame 123, the movable body 12 moves the first urging member 1
Since it is moved upward by 6, the latch head 13 which has passed over the lower rail 2a is moved downward by the second urging member 17 again, as shown in FIG. Maintained above. Therefore, when the folding door is opened, the latch head 13 does not damage the bathroom floor 30 and the latch head itself is not damaged.

In the case where the actuating members AM are provided on the left and right doors d1 and d2 as in the above embodiment, the driven member when the folding door is closed is closed.
Since the pressing force is applied from the drive cams 26 of both actuating members AM to both cam surfaces of the frame 123, the movable body 12 moves stably, smoothly and surely downward. Therefore, deterioration or damage due to mechanical fatigue such as when a force is applied to only one side is prevented, and the load received from the movable body 12 is also distributed to the operating member AM, so that deterioration or damage is similarly prevented. Further, since the notches 9b having the same shape are simply formed in the connecting portion side frames 91 and 92 of both doors, the processing and member management are easy.

However, the present invention can be carried out in a form in which the actuating member AM is attached to either one of the left and right doors. Moreover, in any case, the same latch unit can be commonly used. Since the latch unit LU is attached to the connecting member 5, the operating member A
The coupling member 5 can be processed regardless of whether M is attached to one or both doors.
Therefore, the latch lock device can be easily attached.
