Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a locking device for a sliding door that can be locked with both sides of the sliding door open.

[Conventional technology]

The common method for locking sliding doors made of aluminum or other metal is to use a crescent lock installed between the vertical frames of the opposing sliding door frames with the window closed.

[The problem that the idea aims to solve]

Therefore, the door cannot be locked unless both sliding door frames are completely tightened, and the only way to ventilate the room with the windows locked during the summer is to use forced ventilation using a ventilation fan.

It was also used as a locking device for shutters that allowed ventilation in the summer with the shutters closed.
There is one disclosed in Publication No. -7073. According to this, it is possible to lock the shutters at night in the summer or when going out without having to completely close the shutters, that is, with the shutters slightly open for ventilation. However, in this conventional design, the central part of the sliding shutter (the gap between the two shutters) is opened slightly, and the sliding shutter does not open on both sides. A lock is attached to each storm door, and the lock is dropped into a lock hole provided in the rail of the storm door, but this operation must be performed by identifying the lock hole.

The object of the present invention is to provide a locking device for a sliding door that can be easily locked at any position, in addition to when the sliding door is left slightly open on both sides.

[Means for solving problems]

In order to achieve the above object, the present invention includes a locking piece having a large number of locking holes drilled in the longitudinal direction on the inner surface of one sliding door frame of a sliding door so as to protrude so as to overlap with the other sliding door frame, The other sliding door frame is provided with a locking piece with one locking hole, a number of locking grooves are formed in the longitudinal direction on the bottom piece of the window frame, and any locking hole in the locking piece of both sliding door frames is provided. and a shallow groove in which a locking member passes through and locks in an arbitrary locking groove on the bottom piece of the window frame, and a wheel provided on the sliding door frame fits into a running rail of the sliding door frame that projects from the bottom piece of the window frame. The gist is that the locking hole of the locking piece of the sliding door frame and the locking groove of the bottom piece of the window frame match when the wheel is inserted into the shallow groove.

〔Example〕

The sliding door frame of the present invention will be explained below based on the illustrated embodiment.

In the figure, reference numeral 1 denotes a window frame fixed to pillars or other parts of the building body, and the shape of this window frame 1 is constructed in the same manner as a conventional sash. In the present invention, the sliding door frame 2, 3 is attached to the bottom piece 11 between the two parallel running rails 12, 12 of the sliding door frame provided on the bottom piece 11 of the window frame 1.
A large number of locking grooves or locking holes (simply referred to as "locking holes") at regular or arbitrary intervals in the moving direction (sliding direction).
That's what it means. )13,13... are formed. The V-shaped locking groove 13 can be formed over the entire length of the bottom piece 11, but it can also be formed only on both sides of the window frame except for the center. Reference numerals 14 and 15 indicate water sections that are bent and connected to the inside and outside of the bottom piece 11 of the window frame 1.

Reference numeral 2 indicates one sliding door frame of the sliding door, and a wheel (not shown) is provided at the bottom and is supported on the rail 12 to enable the sliding door frame 2 to move along the rail 12. A locking piece is provided on the vertical frame 21 and the lower frame 22 of the sliding door frame 2 or only on the lower frame 22 so as to protrude toward the other side of the sliding door frame 3 and inserted into the lower part of the lower frame 32 of the sliding door frame. 23
is installed almost horizontally. This locking piece 23 is attached to the sliding door frame 2.
The locking piece 23 is provided over the entire length of the lower frame 22, or its length is determined according to the permissible opening range of the sliding door frame, and a large number of locking holes 24 are bored at predetermined intervals in the longitudinal direction of the locking piece 23. Note that this locking piece 23 protrudes from the lower frame 22 in the horizontal direction;
When moving, avoid contact with the sliding door frame 3 on the other side, the bottom piece 11 of the window frame, the rail 12, etc.

The sliding door frame 3 on the other side is usually provided with a locking rod 4 as a locking member in the vertical frame 31 on the side where a crescent lock or the like is provided, or vertically along the vertical frame 31. By operating the provided operating lever 41, the lower end of the locking rod 4 is made to protrude and retract from the locking hole 34 of the locking piece 33 provided at the lower part of the vertical frame 31. At this time, the locking rod 4 is positioned such that it can be inserted into any one of the locking holes 24 arranged in a straight line.

Moreover, this locking rod can also be made to protrude both above and below the sliding door frame 3.

Further, a shallow groove 12a is formed in the rail 12 so that the position of the locking groove 13 can be easily and reliably confirmed.
When the wheels provided at the lower part of the sliding door frames 2 and 3 fit into the shallow groove 12a, the locking groove 12a
3 and the locking holes 24, 34 are aligned vertically,
In addition, the locking rod 4 is positioned above the locking groove and the locking holes 13, 24, and 34, and the shallow groove 12a allows the wheels to move smoothly on the rail 12. Shape it into a gentle V-shape. When the wheel falls into this shallow groove, if the locking rod is lowered, it can easily penetrate into the locking groove and the locking holes 13, 24, and 34.
As a result, the sliding door frames 2 and 3 are locked to the window frame 1, and the sliding door frames 2 and 3 are locked.

Furthermore, the vertical frames 25, 35 on the outside of the sliding door frames 2, 3
Insect net devices 5 and 6 can also be provided respectively.
The insect screen devices 5, 6 are of a folding type or a roll-up type, and the housings 51, 61 for storing the insect screens 50, 60 are attached to the vertical frames 25, 35 of the sliding door frames 2, 3.
It may be integrally formed within the vertical frame 25, 35.
These housings 51 and 61
The insect nets 50, 60 are pulled out so that they can be pulled out and stored, and the frames 52, 62 provided at the tips of the insect nets 50, 60 are locked to the vertical frames 16, 17 of the window frame 1.

Therefore, in order to open the window frame on both sides of the sliding door frame configured as described above and install an insect screen, first move the reciprocating sliding door frames 2 and 3, respectively, as shown in Fig. 1. Then, only the required size is opened in the window frame. At this time, move the sliding door frames 2 and 3,
When the wheel R is stopped in a state where it is fitted into the shallow groove 12a closest to an arbitrary position, one of the locking holes 24, 34 and the locking groove 13 of the window frame bottom piece naturally match. Next, when the locking rod 4 is lowered from above and fitted into the locking hole 24 and the locking groove 13 which are vertically aligned, both sliding door frames 2 and 3 are locked to the window frame 1 and locked.

In addition, if the frames 52 and 62 of the insect screen main body are locked to the vertical frames 16 and 17 of the sliding door frame, they will follow the opening and closing operations of the sliding door frame, and the insect screen will always be stretched over the window opening position. .

In addition, in the above embodiment, the explanation was given as a sliding door, but
There is no limit to the size or use of this window, and it can be applied to high windows, bay windows, sweeping windows, general windows, and sliding doors for entrances and exits.

[Effect of idea]

According to the present invention, it is possible to lock the sliding door at any position in addition to the open state on both sides of the window frame, and when locking, it is possible to easily connect the locking member to the locking hole and the locking groove. It can be easily locked. Therefore, the locking device has advantages such as being able to safely ventilate the room even at night or when going out, and having a simple structure so that the locking device can be provided at a low cost.
