Next, another embodiment shown in FIGS. 8 to 16 will be described. In the description of the other embodiments, the same portions as those of the first embodiment are denoted by the same or similar reference numerals, and duplicate description will be omitted.

FIGS. 8 and 9 show a second embodiment of the present invention. The second embodiment differs from the first embodiment mainly in that the upper surface 12 of the left (one) sickle receiving sliding piece 3A is provided.
And a horizontal support plate-shaped spring end support arm 41 for receiving the upper surface of the right (other) sickle receiving slide piece 3. The spring end support arm 41 extends from the center of the upper surface 12 of the left sickle receiving sliding piece 3A to the upper surface 12 of the other sickle receiving sliding piece 3. Therefore, in this embodiment, there is one spring member 8A. The spring end support arm 41 of this embodiment is formed integrally on the upper surface 12 of one of the sickle receiving sliding pieces 3A.
Unity is not a specific requirement of the invention. The spring end support arm 41 may be a separate rectangular support plate, and may be placed on each of the upper surfaces 12 of the left and right sickle receiving sliding pieces 3A, 3.

In the above configuration, the tip 4a of the sickle piece 4
However, for example, as shown in FIG. 9, when the stepped intermediate engaging portion 9b of the left sickle receiving sliding piece 3A and the stepped upper engaging portion 9a of the right sickle receiving sliding piece 3 are respectively engaged, Only the one sickle receiving sliding piece 3A is lifted against the spring force of the spring member 8A.

However, when the operating member 23 is raised by operating the operating piece 21 shown in FIG. 2 and the sickle piece 4 is brought into a non-engaged state, the other sickle receiving sliding piece 3 is moved by its own weight or The sickle receiving sliding piece 3A returned downward by the spring member 8A descends.

FIGS. 10 and 11 show a third embodiment of the present invention. The third embodiment is different from the first embodiment mainly in that the left and right scythe receiving slides 3B, 3B have upper surfaces 1B.
Opposite cutouts 42, 42 into which the tip 4a of the sickle piece 4 enters are formed at one end of 2B, 12B. The right and left symmetric inverted step receiving portions 9 for locking the intermediate portion 4c of the sickle piece 4 on one side wall 36B of the left and right sickle receiving sliding pieces 3B, 3B.

The inner wall surface of 8B is usually a general wall surface shape, and is different in that it does not have a stepped shape. The opposed notch 4
The total width of 2, 42 is set wider than the width of the tip 4a of the sickle piece 4. Also, two spring members 8B are used as in the first embodiment.

In the above configuration, one side wall 36B of the left and right sickle receiving sliding pieces 3B, 3B faces the inner wall surface of the vertical plate 2a of the outer frame 2. Therefore, when the operating member 23 is lowered by the operation of the operation piece 21 of FIG. 2 and the sickle piece 4 is engaged as a result, unlike the first embodiment, as shown in FIG. Of the left and right sickle receiving sliding pieces 3B, 3
B penetrates into the opposed notches 42, 42 of B, and at the same time, the middle part 4c of the sickle piece 4 engages the left and right symmetric inverted step receiving part 9B.

FIGS. 12 and 13 show a fourth embodiment of the present invention. The fourth embodiment is different from the second embodiment described above in the third embodiment.
This is a type in which the embodiment is combined. Therefore, in order to avoid redundant description, the differences from the first embodiment will be listed using the same reference numerals as those used in these embodiments. First, a spring end support arm 4 that receives the upper end edge 12C of the right sickle receiving sliding piece 3C on the upper end edge 12C of the vertical opposing side wall 38C that intersects the one side wall 36C of the left sickle receiving sliding piece 3C.
1C is provided. The spring end support arm 41C is a wide horizontal plate as in the second embodiment. This wide horizontal plate 4
Although 1C is formed integrally with the upper end edge 12C in the present embodiment, it is sufficient if it has a function of receiving the spring member 8C, and thus may be separate from the upper end edge 12C. In this case (separate body), it is desirable that both ends of the support plate be placed on the upper edge 12C of the vertical opposing side wall 38C or on the upper surface appropriately extended to the upper edge. There is one spring member 8C. The upper edges 12C of the left and right sickle receiving sliding pieces 3C, 3C are L-shaped and do not have an upper surface. Therefore, the tip of the sickle piece 4 enters the rectangular opening 45 formed by both the left and right sickle receiving sliding pieces 3C, 3C. The inner wall surface of the vertical opposing side wall 38C has a general wall surface shape and does not have a stepped shape. Left and right symmetric inverted step receiving portions 9C for locking the intermediate portion 4c of the sickle piece 4 are formed on one side wall 36C of the left and right sickle receiving sliding pieces 3C.

In the above configuration, one side wall 36C of the left and right sickle receiving sliding pieces 3C, 3C faces the inner wall surface of the vertical plate 2a of the outer frame 2. Therefore, when the operating member 23 is lowered by the operation of the operation piece 21 of FIG. 2 and the sickle piece 4 is engaged as a result, unlike the first embodiment, as shown in FIG. Of the left and right sickle receiving sliding pieces 3C, 3
The middle part 4c of the sickle piece 4 engages with the right and left symmetrical inverted step receiving part 9C at the same time. Therefore, the operation of this embodiment is the same as that of the third embodiment.

FIGS. 14 to 16 show a fifth embodiment of the present invention. The fifth embodiment is different from the first embodiment mainly in a sickle receiving turning piece 3D. The term “sickle receiving rotating piece 3D” is suitable for the sickle receiving sliding piece of this embodiment, so that the term is used.

First, the left and right sickle receiving sliding pieces 3 and 3 of the first embodiment are mounted inside the outer frame 2 so as to be able to move up and down against the spring force of the spring member 8. Is different in that the sickle receiving turning piece 3D is composed of a large number of turning plates 47 rotatably supported by a fixed shaft 46 horizontally mounted on the outer frame 2. The rotating plates 47 are all fan-shaped, and a total of 12 rotating plates are used in this embodiment. It is desirable that the number of the rotating plates 47 be 4 or more and 19 or less.

Next, the left and right sickle receiving sliding pieces 3, 3 of the first embodiment are mounted so as to be vertically movable against the spring force of the two spring members 8, respectively. Is different in that it rotates against the spring force of a large number of pressing finger portions 49 formed on a leaf spring member 8D which is an example of a spring member. The plurality of pressing fingers 49 selectively engage with the sickle piece 4 corresponding to the closed position of the sliding door.

The leaf spring member 8D has a small through-hole 51 for the fixing tool 50 at the base end thereof.
0, and is appropriately attached to the inner wall surface of the outer frame 2. At that time, a portion near the base end of the leaf spring member 8D is provided with a support rod 52 fixedly laterally mounted on the outer frame 2 in the same manner as the fixed shaft 46 described above.
Supported by

By the way, as shown in FIG. 16, each of the pressing finger portions 49 is disposed below each of the rotating plates 47 so as to correspond to each other. Thus, a total of twelve are provided. This is similar to "for example, a music box vibration valve having a slit".

Therefore, when the leaf spring member 8D is fixed to the inner wall surface of the outer frame 2, both sides of the pressing finger portion 49 have a meaning as a reference finger for positioning with respect to each rotating plate 47.

FIG. 14 shows a case in which the sickle piece 4 is in a non-engaged state in the above configuration. In this case, since all the rotating plates 47 are supported equally by the pressing finger portions 49, they are in a so-called aligned state. On the other hand, FIG. 15 shows a case where the sickle piece 4 is engaged. In this case, not the tip of the scythe piece 4 but the slightly curved outer wall surface 4d from the tip 4a of the scythe piece 4 to the intermediate portion 4c is in sliding contact with a part of the peripheral wall surface of each corresponding pressing finger portion 49.

As a result, as shown in FIGS. 15 and 16, several rotating plates 47 pressed by the curved outer wall surface 4 d of the sickle piece 4 move downward while resisting the spring force of each pressing finger 49. (Some clockwise rotation). At this time, the sickle piece 4 engaged is held in a locked state by the left and right rotating plates 47 that have not rotated.

When the operating member 23 is raised by the operation of the operating piece 21 shown in FIG. 2 and the sickle piece 4 is brought into a non-engaged state, each of the rotating plates 47 which has disturbed the alignment state has the spring member 8D. It returns to the initial position by the spring force.

[0041]

As is apparent from the above description, the present invention has the following operations and effects. (1) Even if there is a slight displacement of the sliding door when the sliding door is closed, the sickle piece can be locked or locked. Therefore, in the present invention, there is no need to attach the optional automatic closing device separately from the sickle lock device. A third object is to improve the efficiency of the attaching work of the sickle lock device. (2) The allowable range of the displacement of the sliding door can be expanded as much as possible. (3) Since the pair of left and right sickle receiving slides has a stepped receiving portion for receiving the sickle, so-called fine adjustment is not required even if the mounting position of the sickle is slightly shifted. In particular, when the step-shaped receiving portion is step-shaped, the efficiency of the operation of attaching the sickle lock device can be improved. (4) In the case of the fifth embodiment, it is possible to delicately cope with a displacement of the sliding door.
