When the sliding doors 1 and 6 are closed with each other, the center of a vertical plate 2a facing the inner frame 5 is closed. A sickle piece window 7 is formed in the portion from the part or the center. The opening width of the sickle piece window 7 is formed slightly wider in consideration of the engagement width of the sickle catcher 3. In addition, outer frame 2 here
Also includes a case-like support frame fixedly installed in the frame.

In the outer frame 2, a single sickle catcher 3 is provided so as to be able to swing against the spring force of the spring member, facing the sickle piece window 7.

Referring to FIG. 3, first, the sickle catcher 3 is a rectangular block piece as a whole, and has two fixed shaft holes 8 described below in a horizontal direction at a lower portion. More precisely, these shaft holes 8, 8 are formed in extended lower end portions 9a, 9a connected to the left and right side wall portions 9 facing the inner wall surface of the outer frame 2. A notch 11 for assembling the spring member 10 communicating with the horizontal shaft holes 8, 8 is formed at the center of the extended lower ends 9a, 9a. In the present embodiment, the extended lower ends 9a, 9a have a function as bearings.

Next, when the sickle catcher 3 moves in the direction A for closing the inside and outside or the left and right sliding doors 6 and 1, respectively, the engagement position with the sickle piece 4 changes the ratchet tooth-shaped engaging portion 12.
And a fixed shaft 13 laid horizontally on the frame 2 so as to be able to swing against the spring force of the spring member 10.
It is pivoted on.

By the way, generally, "ratchet teeth"
Means a circumferential engaging tooth formed on a gear rotating with respect to the shaft. However, here, the meaning of "ratchet teeth" is moved together with the sliding door when the sliding door is horizontally moved in the closing direction A, but the movement of the sliding door (return of the sliding door) is prevented in the opening direction of the sliding door. Used as a parallel engagement tooth with function.

Accordingly, the ratchet tooth-shaped engaging portion 12 has a diagonal slide engaging surface 12a which slides and engages with the distal end portion 4a of the sickle piece 4, and the slide engaging surface 12a.
a is separated from a parallel locking surface 12b formed so as to lock the tip 4a of the sickle piece 4 with respect to the sickle piece 4, and the horizontally moving sickle piece 4 can be moved in one direction, but in the opposite direction. Will have a function that cannot be moved.

In the present embodiment, the sickle piece 4 is composed of a total of five engaging claw pieces combined in a stepped manner, and at least two engaging claw pieces projecting outwardly are formed as ratchet teeth of the sickle catcher 3 as shown in the figure. And simultaneously engage with the engagement member 12. In addition, sickle piece 4
Selectively engages with the ratchet teeth-shaped engaging portion 12 corresponding to the closed position.

As shown in FIG. 4, the sickle catcher 3
It is supported by a fixed shaft 13 that is horizontally mounted on the outer frame 2.
The sickle catcher 3 is individually urged by spring members 10 mounted on the fixed shafts 13 respectively. The spring member 10 is incorporated in the notch 11 as described above,
One end 10a is pressed against the lower surface of the outer wall of the sickle catcher 3, while the other end 10b is pressed against a support plate, a fixed frame and the like in the frame 2.

Therefore, the sickle catcher 3 is pivotally supported by the fixed shaft 13 so as to be able to swing against the spring force of the spring member 10.

FIG. 2 shows an environmental member related to the sickle piece 4. Each environmental member will be described briefly.
Reference numeral 15 denotes a sickle doorway 1 capable of facing the sickle window 7 of the outer frame 2.
Reference numeral 17 denotes a case-shaped fixed frame incorporated in the opening 18 of the inner frame 5, and 19 denotes an inner cover (commonly referred to as an inner escation) fixed to the inner frame 5 via a plurality of fasteners 20. ), 21 are operation pieces having a cross-shaped cross section incorporated in cutouts 22 formed in the inner wall surface of the inner cover, and 23 is mounted on the case-shaped fixed frame 17 so as to be vertically movable (meaning that it can slide freely). It is a frame-shaped operating member. This frame-shaped operating member 23
And the operation piece 21 are integrally provided and function as a driving member.

The guide small notch 2 for the knob 21a of the operation piece 21 is provided on the inner cover (commonly called inner escation) 19.
5 and the like are formed. Further, the case-shaped fixed frame 17 is also formed with a window-shaped opening 27 that matches the small guide cutout 26 of the operation piece 21 and the sickle piece entrance 16 of the front 15.

The rear end 4b of the sickle piece
Operating member 2 which is supported by a fixed support shaft 30 which is horizontally mounted on a shaft and which is engaged with a T-shaped engagement hole formed at a rear end portion.
3 is locked to the operating shaft 31.

FIGS. 5 and 6 show that the sickle catcher 3 is pressed by the spring member 10 and stops at the initial position, and
It shows that the sickle piece 4 is in a non-engaged state. In this non-engagement state, when the operating member 23 is lowered by operating the operation piece 21, the sickle piece 4 rotates about the fixed support shaft 30.

FIGS. 7 and 8 show a case where the sliding doors 1 and 6 are closed, and even if the sliding doors are slightly displaced, they are ignored and the sickle piece 4 is turned in the engaging (engaging) direction. The state of is shown. In this case, with reference to FIG. 7, a state is shown in which the tip 4a of the sickle piece 4 is engaged with the right side of the engaging portion 12a of the catcher 3.

Here, a case where the outer (right) side sliding door 1 is closed in the direction of arrow A will be described with reference to FIG. It is assumed that the scythe piece 4 has been hooked on the scythe catcher 3 even though a slight gap a has occurred between the scythe and the door frame 40. In this case, the two engaging claws protruding from the sickle piece are selectively inserted into the corresponding engaging grooves. Sickle piece 4 is operation piece 2
It does not rotate unless the actuating member 23 is pulled up at 1. On the other hand, the sickle catcher 3 can swing against the spring force of the spring member 10.

Therefore, when one of the sliding doors 1 and 6, for example, the outer sliding door 1 is pulled in the closing direction A, the two engaging claw pieces are added in the sliding contact direction of the sliding engaging surface 12a of the sickle catcher 3. Therefore, if the return force of the spring member 10 that prevents the sickle catcher 3 from swinging exceeds its limit,
The sickle catcher 3 swings backward against the spring force of the spring member 10. As a result, the engaging claw of the sickle piece 4 is
The sliding door 1 is completely closed with respect to the door frame 40 by passing through the one or more engaging grooves and engaging with the other engaging grooves.

In this embodiment, the sickle catcher 3 is upwardly directed with reference to FIG. 2 in consideration of the engagement with the sickle piece 4. Therefore, if the tip 4a of the sickle engages downward depending on how the sickle piece 4 is attached, the sickle catcher 3 is naturally pivotally supported downward. Further, the sickle piece 4 has two engaging claw pieces that simultaneously engage with the engaging teeth of the engaging portion 12 of the sickle catcher 3 when engaged, but in order to enhance the effect of the locking function of the sickle lock device, Two or more sheets may be used.

Further, in this embodiment, the ratchet tooth-shaped engaging portion is formed on the opposing surface of the sickle catcher 3 and both edges of the sickle engaging claw are straight. By adopting the technical principle, for example, as shown in FIG. 10, an engaging portion 12A having a rectangular (rectangular) cross section is formed on the opposing surface of the sickle piece 4A of the sickle catcher 3A. Even if one side of the portion is formed in a tapered shape, it is a matter within a so-called "uniform" range.

Therefore, in the case of this equivalent example, a tapered slide engagement surface which is in sliding contact with the engagement portion 12A of the sickle catcher 3A is formed on one side of the tip 4a of the sickle piece 4A. Even with such a configuration, the object of the present invention can be achieved.
