Each sickle receiving slide piece 3, 3 is preferably guided by a guide portion (for example, a guide groove) provided or formed on the inner wall surface of the outer casing 2. Further, the sickle piece 4 rotates following the vertical movement of the actuating member 23, but the actuating member 23 may be of a type that moves back and forth in the horizontal direction depending on the design.
[0024]
Next, another embodiment shown in FIGS. 8 to 16 will be described. In the description of the other embodiments, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant description is omitted.
[0025]
8 and 9 show a second embodiment of the present invention. In the second embodiment, the main difference from the first embodiment is that the upper surface 12 of the left (one) sickle receiver sliding piece 3A receives the upper surface of the right (other) sickle receiver sliding piece 3. This is because a horizontal support plate-like spring end support arm 41 is provided. The spring end support arm portion 41 extends from the center portion of the upper surface 12 of the left sickle receiving sliding piece 3 </ b> A to the upper surface 12 of the other sickle receiving sliding piece 3. Therefore, in this embodiment, there is one spring member 8A. In addition, although the spring end support arm 41 of this embodiment is integrally formed on the upper surface 12 of one sickle receiving sliding piece 3A, it is not a specific requirement of the invention to be integrated. The spring end support arm 41 may be a separate rectangular support plate and placed on each upper surface 12 of the left and right sickle receiver sliding pieces 3A, 3.
[0026]
In the above configuration, the tip portion 4a of the sickle piece 4 has a stepped intermediate engagement portion 9b of the left sickle receiver sliding piece 3A and a stepped upper engagement of the right sickle receiver sliding piece 3 as shown in FIG. When engaged with the joint portions 9a, only the one sickle support sliding piece 3A is lifted against the spring force of the spring member 8A.
[0027]
Therefore, when the operating member 23 is lifted by the operation of the operating piece 21 of FIG. 2 to be used and, as a result, the sickle piece 4 is brought into the non-engagement state, the other sickle receiving slide piece 3 is caused by its own weight or the spring member 8A. It descends through one sickle receiving sliding piece 3A returned downward.
[0028]
10 and 11 show a third embodiment of the present invention. In the third embodiment, the main difference from the first embodiment is that the tip 4a of the sickle piece 4 enters the one end of the upper surfaces 12B, 12B of the left and right sickle receiving sliding pieces 3B, 3B. That is, the notches 42 are formed. Further, the left and right inverted inverted step receiving portions 9B for locking the intermediate portion 4c of the sickle piece 4 are formed on one side wall 36B of the left and right sickle receiving sliding pieces 3B, 3B. Further, in the third embodiment, the inner wall surface of the vertical opposing side wall 38B intersecting with the one side wall 36B is usually a general wall surface shape, and is different in that it is not stepped. The total width of the opposed notches 42 and 42 is set wider than the width of the tip portion 4 a of the sickle piece 4. Further, two spring members 8B are used as in the first embodiment.
[0029]
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 casing 2. Therefore, when the operating member 23 is lowered by the operation of the operating piece 21 of FIG. 2 to be used and, as a result, the sickle piece 4 is engaged, the sickle piece 4 is different from the first embodiment as shown in FIG. The front end 4a of the right and left sickle receiving slide pieces 3B and 3B penetrates into the opposite notches 42 and 42, and at the same time, the intermediate part 4c of the sickle piece 4 is engaged with the left and right target inverted step receiving part 9B. Match.
[0030]
12 and 13 show a fourth embodiment of the present invention. The fourth embodiment is a type in which the second embodiment and the third embodiment described above are combined. Therefore, in order to avoid duplication, different points from the first embodiment are listed using the same symbols as those used in these embodiments.
(1) First, a spring end support arm 41C for receiving the upper edge 12C of the right sickle receiving sliding piece 3C on the upper end edge 12C of the vertical opposing side wall 38C intersecting the one side wall 36C of the left sickle receiving sliding piece 3C. Is provided. The spring end support arm 41C is a wide horizontal plate as in the second embodiment. The wide horizontal plate 41C is integrally formed with the upper end edge 12C in this embodiment, but it is sufficient if it has a function of receiving the spring member 8C. Therefore, even if it is separate from the upper end edge 12C. good. In this (separate body), it is desirable to place both ends of the support plate on the upper end edge 12C of the vertically opposed side wall 38C or on the upper surface appropriately extended to the upper end edge.
(2) There is one spring member 8C.
(3) The upper edge 12C of the left and right sickle receiver sliding pieces 3C, 3C is L-shaped and has no upper surface.
Therefore, the tip of the sickle piece 4 enters the rectangular opening 45 formed by both the left and right sickle receiver sliding pieces 3C and 3C.
{Circle around (4)} The inner wall surface of the vertical opposing side wall 38 </ b> C is generally a general wall surface shape and is not stepped.
{Circle around (5)} Left and right inverted 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 slide pieces 3C, 3C.
[0031]
In the above configuration, one side wall 36C of the left and right sickle receiver sliding pieces 3C, 3C faces the inner wall surface of the vertical plate 2a of the outer casing 2. Therefore, when the operating member 23 is lowered by the operation of the operating piece 21 of FIG. 2 and the sickle piece 4 is engaged, the sickle piece 4 is different from the first embodiment as shown in FIG. The front end portion 4a of the left and right sickle receiving slide pieces 3C and 3C enters the rectangular opening 45 so that the intermediate portion 4c of the sickle piece 4 engages with the inverted vertical step receiving portion 9C. Therefore, the operation of this embodiment is the same as that of the third embodiment.
[0032]
14 to 16 show a fifth embodiment of the present invention. In the fifth embodiment, the main difference from the first embodiment is a sickle receiving rotating piece 3D. The term “sickle receiver rotating piece 3D” is appropriate for the sickle receiver sliding piece of this embodiment, and this term will be used.
[0033]
First, the left and right sickle receiver sliding pieces 3 and 3 of the first embodiment are housed in the outer casing 2 so as to be movable up and down against the spring force of the spring member 8. The rotating piece 3D is different in that the rotating piece 3D includes a large number of rotating plates 47 that are pivotally supported by a fixed shaft 46 that is horizontally mounted on the outer casing 2. All the rotating plates 47 have a fan shape, and a total of 12 plates are used in this embodiment. The number of the rotating plates 47 is desirably 4 or more and 19 or less.
[0034]
Next, the left and right sickle receiver sliding pieces 3 and 3 of the first embodiment are mounted so as to be movable up and down against the spring force of the two spring members 8, respectively. The rotating piece 3D 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 that is an example of a spring member. The large number of pressing finger portions 49 selectively engage with the sickle piece 4 corresponding to the closed position of the sliding door.
[0035]
The leaf spring member 8 </ b> D has a through hole 51 for the fixing tool 50 at the base end portion, and is appropriately attached to the inner wall surface of the outer casing 2 through the through hole 51 and the fixing tool 50. At this time, a portion near the base end portion of the leaf spring member 8D is supported by a support bar 52 fixedly provided on the outer casing 2 in the same manner as the fixed shaft 46 described above.
[0036]
By the way, as shown in FIG. 16, the pressing finger portions 49 are disposed so as to correspond to the lower portions of the rotating plates 47, respectively. In this embodiment, the total number of the pressing fingers 49 corresponds to the number of the rotating plates 47. Twelve are provided. This is similar to “for example a music box vibration valve with a slit”.
[0037]
Therefore, when the leaf spring member 8D is fixed to the inner wall surface of the outer casing 2, both sides of the pressing finger portion 49 have meaning as alignment reference fingers with respect to the respective rotation plates 47.
[0038]
In the above configuration, FIG. 14 shows a case where the sickle piece 4 is not engaged. In this case, the rotating plates 47 are all supported by the pressing finger portions 49 in an equal state, so that they are in a so-called aligned state. On the other hand, FIG. 15 shows a case where the sickle piece 4 is in the engaged state. In this case, rather than the tip portion of the sickle piece 4, the slightly curved outer wall surface 4 d from the tip portion 4 a of the sickle piece 4 to the intermediate portion 4 c is in sliding contact with a part of the peripheral wall surface of each corresponding pressing finger portion 49.
[0039]
As a result, as shown in FIGS. 15 and 16, several rotating plates 47 pushed by the curved outer wall surface 4d of the sickle piece 4 are moved downward (half-clockwise) against the spring force of each pressing finger portion 49. ). The sickle piece 4 engaged at this time is sandwiched between the left and right rotating plates 47 which have not been rotated.
[0040]
When the operating member 23 is raised by the operation of the operating piece 21 of FIG. 2 to be used and as a result, the sickle piece 4 is in the non-engagement state, each rotating plate 47 disturbed in the aligned state is caused by the spring force of the spring member 8D. Return to the initial position.
[0041]
【The invention's effect】
As is clear from the above description, the present invention has the following actions and effects.
(1) When the sliding door is closed, the sickle piece can be locked or locked even if the sliding door is slightly misaligned. Therefore, in the present invention, there is no need to attach the optional automatic closing device separately from the sickle lock device.
The third object is to improve the efficiency of the attachment work of the sickle lock device.
(2) The allowable range of sliding door displacement can be expanded as much as possible.
(3) Since the pair of left and right sickle receiving slide pieces have stepped receiving parts for receiving the sickle pieces, there is no need for so-called fine adjustment even if the attachment positions of the sickle pieces are slightly shifted. In particular, when the stepped receiving portion is stepped, it is possible to improve the efficiency of attaching the sickle lock device.
(4) In the case of the fifth embodiment, it is possible to delicately cope with the displacement of the sliding door.
