In this way, a plate-shaped sickle operating member (drive link) that is directly connected to the conventional sickle member and is movably arranged in the direction in which the sickle lock body extends is generally a sickle operating member. The distance between the supporting front point (connecting point with the sickle member) and the rear point (locking point with the operating member) is long. Further, in the sickle operating member, the connection point between the sickle member and the operating member is not on the center in the width direction in the plan view of the sickle operating member, but is slightly deviated in the width direction. This is because these connecting points are the locking of the through hole formed in the sickle operating member and the short axis protruding in the lateral direction of the sickle member or the operating member. In this case, the thin sickle operating member tends to bend in the width direction due to the acting force applied to the sickle operating member during locking and unlocking (see FIG. 9). In fact, in the sickle-shaped main body 100 of FIG. 7C, the bending of the sickle operating member 102 has been confirmed in a pushing test in which the sickle member 101 is strongly pressed from the outside to the inside.

The sickle lock 10A has a sickle lock body 10 that extends inward from the tip surface of the sliding door facing the receiver 7 provided on the doorway configuration frame that is opened and closed by the sliding door. The sickle lock main body 10 has a plate-shaped sickle operating member 2, a sickle member 1, a connecting member 3 interposed between the sickle operating member 2 and the sickle member 1, and an operating member 4 for operating the sickle operating member 2. ..

The sickle operating member 2 is movably arranged on the rear side of the sickle lock body 10 in the direction in which the sickle lock body 10 extends, and is rotatably connected to the rear connecting point 31 of the connecting member 3 on the front side. A notch 22 for locking the first connecting point 21 to the operating member 4 is provided on the rear side. The rear connection point 31 means a rear connection position in the connection member 3. Although the sickle operating member 2 is a plate-shaped body, the length in the extending direction of the sickle lock body 10 can be shortened as compared with the conventional sickle operating member 2, so that the problem of bending in the indentation test does not occur. The first connecting point 21 is a first shaft hole which is a through hole, and a first short shaft which is a rear connecting point 31 of the connecting member 3 is rotatably fitted. Further, the cutout portion 22 is cut out from the lower end to the upper side in the lower part on the rear side of the plate-shaped body. The notch shape corresponds to the shape of the tip locking portion 42 of the operating member 4, and is a mountain shape and the top of the mountain is a quadrangle.

The sickle actuating member 2 has a front guide groove 24 extending rearward from the front end and a rear guide groove 23 extending forward from the rear end slightly below the front guide groove 24. The front guide groove 24 and the rear guide groove 23 are guided by the short shafts 62 and 63 attached to the left case member 6a of the sickle lock body 10, respectively, and the sickle lock body 10 of the sickle actuating member 2 extends.

A concave portion 251 is formed at the upper end of the rear side of the sickle operating member 2, and a convex portion 252 is formed on the front side adjacent to the concave portion 251. As a result, concave portions are formed before and after the convex portion 252, respectively. A small protrusion 54 at the front end of the return prevention member 5 is locked in this recess, whereby the movement of the sickle actuating member 2 at the time of locking and unlocking is restricted.

The sickle member 1 has a predetermined length pivotally supported on the front side of the sickle lock body 10 so as to swing between the locking position and the unlocking position, and has a predetermined length and a front connecting point 32 of the connecting member 10. It has a second connecting point 11 that is rotatably connected. The second connecting point 11 is a second shaft hole which is a through hole, and a second short shaft which is a front connecting point 32 of the connecting member 3 is rotatably fitted. The pivot point where the sickle member 1 is pivotally supported by the left and right side case members 6a and 6b of the sickle lock body 10 is located at the end of the sickle member 1 in the direction opposite to the sickle neck 13, and the short axis 12 extending outward. Is. That is, in this example, since the second connecting point 11 of the sickle member 1 is located above the short axis 12 which is the pivot point, the sickle neck 13 is a movement that rotates downward at the time of locking and at the time of unlocking. , It becomes a movement to rotate upward. The thickness of the sickle neck 13 of the sickle member 1 and the thickness of the base to which the short shaft 12 is attached are both dimensional so as to form a very slight gap between the case members 6a and 6b on both sides.

The connecting member 3 is interposed between the sickle operating member 2 and the sickle member 1, and has a front connecting point 32 that rotatably connects to the second connecting point 11 of the sickle member 1 and a first connecting point 21 of the sickle operating member 2. It has a rear connecting point 31 that is rotatably connected to the sickle. The front connection point refers to the front connection position, and the first connection point refers to the first connection position. The second connecting point 11 of the sickle member 1 is the second shaft hole, and the front connecting point 32 of the connecting member 3 is the second short shaft that fits into the second shaft hole. Further, the first connecting point 21 of the sickle operating member 2 is the first shaft hole, and the rear connecting point 31 of the connecting member 3 is the first short shaft that fits into the first shaft hole. That is, the connecting member 3 has a second minor axis formed at the front end and the first minor axis formed at the rear end, and the protruding direction of the first minor axis and the protruding direction of the second minor axis are the sickle lock main body. In the thickness direction of 10, they project in opposite directions. Further, as shown in FIG. 4, the connecting member 3 includes a first member 33 having a corner portion having a thickness (t1) in a plan view, an intermediate base portion 35 bent at a right angle from one end of the first member 33, and an intermediate base portion. The plan view including the second member 34 having a corner portion having a thickness (t2) in a plan view extending in the direction opposite to that of the first member 33 from the bent tip of the 35 is the crank road shape, and the plan view of the intermediate base 35. The thickness (t3) ≦ ((t1) + (t2)). Of these, it is preferable that the thickness (t3) of the intermediate base portion 35 in a plan view is substantially the same as ((t1) + (t2)). As a result, the connecting member 3 can be made thick and highly rigid, and the connection with other members in the width direction can be stabilized.

The operating member 4 is interlocked with an operating lever (not shown) inherent in the first side plate on the back side of the sliding door, and by operating the operating lever, it rotates counterclockwise or clockwise in the side view. The operating member 4 is rotatably arranged on the rear side of the sickle lock body 10 in the same direction as the sickle member 1 rotates, and the tip protrusion 42 is locked to the notch 22 of the sickle operating member 2. It is a thing. The operation member 4 is composed of a horizontal columnar base 41 and a tip protrusion 42 extending upward from the peripheral surface of the base, and a shaft hole 43 into which an operation shaft (not shown) is fitted is formed in the center of the base 41. ing. The operating shaft extends from the operating lever. Therefore, if the operating lever is turned to the left, the operating member 4 also rotates to the left, and if the operating lever is turned to the right, the operating member 4 also rotates to the right. The tip protrusion 42 has a shape corresponding to the square shape of the tip of the notch 22 of the sickle actuating member 2. As a result, the tip protrusion 42 fits into the notch 22, and the sickle operating member 2 can be reliably operated.

The return prevention member 5 is an arbitrary component and holds the movement of the sickle actuating member 2 at the time of locking or unlocking. The return prevention member 5 is a vertically long plate-shaped body, and an upper locking piece 51 that bends in the width direction of the sickle lock body 10 is formed at the upper end, and a lower portion that bends in the width direction of the sickle lock body 10 at the lower end. The locking piece 52 is formed. The upper locking piece 51 is in contact with one end of the spring member 7 fixed to the upper part of the sickle lock body 10, and the lower locking piece 52 is in contact with the tip projection 42 of the operating member 4. Further, a minute protrusion 54 is formed at the front end slightly above in the vertical direction. The microprojection 54 is locked to the unevenness 25 on the upper portion of the sickle operating member 2 to regulate the movement of the sickle operating member 2 at the time of locking or unlocking. Further, a long vertical hole 53 is formed slightly below in the vertical direction. The elongated hole 53 is fitted with a side projection 62 of the left side case member 6a, and guides the return prevention member 5 to move in the vertical direction without shifting in the left-right direction.

The sickle lock main body 10 is formed by incorporating a sickle member 1, a plate-shaped sickle operating member 2, a connecting member 3, and an operating member 4 between the plates 6a and 6b on both sides. That is, the position of the sickle member 1 is determined by fitting the short shaft 12 of the sickle member 1 into the locking hole formed in the left side plate 6a in the front portion of the sickle lock body 10. Next, the position is determined by aligning the front guide groove 24 of the sickle actuating member 2 with the fixed first short shaft 63 of the left plate 6a and aligning the rear guide groove 23 with the fixed second short shaft 62 of the left plate 6a. Next, the second short shaft 32 of the connecting member 23 is fitted into the second shaft hole 11 of the sickle member 1, and the first short shaft 31 of the connecting member 23 is fitted into the first shaft hole 21 of the sickle operating member 2. Next, the base 41 of the operating member 4 is aligned with the shaft penetration holes 61a and 61b of the side plates 6a and 6b. Next, the position is determined by aligning the elongated hole 53 of the return prevention member 5 with the fixed second minor axis 62 (side protrusion) of the left side plate 6a. At this time, the upper locking piece 51 of the return prevention member 5 is made to hit one end of the spring member 7, and the lower locking piece 52 is made to hit the tip protrusion 42 of the operating member 4. As a result, the return prevention member 5 is always spring-forced downward by the spring member 7.

Next, the operation direction of the sickle lock 10A will be described with reference to FIG. FIG. 5A shows a state in which the tip projection 42 of the operating member 4 faces in the forward oblique direction, that is, a state in which the sickle operating member 2 is moved in the forward direction, and is a locked position. That is, the tip protrusion 42 of the operating member 4 is locked to the notch 22 of the sickle operating member 2, and the micro protrusion 54 of the return prevention member 5 is locked to the recess 251 behind the sickle operating member 2. Unless the operating member 4 is operated, the sickle operating member 2 is locked so as not to move forward or backward from this state.

Next, in order to change from the locked state of FIG. 5 (A) to the unlocked state of FIGS. 5 (B) and 5 (C), the operating member 4 is rotated to the right in FIG. As a result, the sickle actuating member 2 moves backward. The sickle actuating member 2 makes a linear motion by the guides of the fixed first short shaft 63 and the fixed second short shaft 62. In conjunction with the backward movement of the sickle operating member 2, the connecting member 3 is also pulled backward, and the sickle neck 13 of the sickle member 1 is lifted (FIG. 5 (B)). When the operating member 4 is in the upright state as shown in FIG. 5B, the return preventing member 5 is lifted against the spring force of the spring member 7, and the return preventing member 5 is placed on the convex portion 252 of the sickle operating member 2. The microprojection 54 will be located. Further, the operating member 4 is rotated to the right in FIG. As a result, the sickle actuating member 2 moves further backward. In conjunction with the backward movement of the sickle operating member 2, the connecting member 3 is also pulled backward, and the sickle neck 13 of the sickle member 1 is completely lifted and unlocked (FIG. 5 (C)). In this state, the microprojection 54 of the return prevention member 5 is locked to the recess 253 in front of the sickle operating member 2, and the sickle operating member 2 moves forward from this state unless the operating member 4 is operated. There is no. This prevents the operation member 4 from changing from the unlocked state to the locked state unless the operating member 4 is operated. Next, in order to change from the unlocked state of FIG. 5 (C) to the locked state of FIGS. 5 (B) and 5 (A), the reverse operation from the locked state to the unlocked state, that is, the operation member 4 is shown in FIG. The operation of rotating the lock to the left may be performed, and the description thereof will be omitted.

In the sickle lock 10A, the connecting member 3 has a specific crank road shape, the thickness of the base is thick, and the first short shaft 31 and the second short shaft 32 at the front and rear ends extend in opposite directions to each other. Therefore, the moving force of the sickle operating member 2 can be transmitted to the sickle member 1 without loss. Further, since the thin sickle operating member 2 is shortened in the direction in which the sickle lock body 10 extends, there is almost no bending in the width direction in the indentation test. Therefore, when the sliding door is strongly closed with the sickle protruding, it is possible to improve the malfunction caused by the sickle colliding with the door pillar.

The sickle lock of the present invention is not limited to the above-described embodiment, and various modifications can be taken. The sickle member 1 is a downward hook that lowers the sickle neck, but is not limited to this, and may be an upward hook that raises the sickle neck. In this case, in the sickle member 1, the pivotal support position of the side plate and the connecting point connected to the connecting member 3 may be turned upside down. That is, the connecting point to be connected to the connecting member 3 may be set below the pivot position, and the sickle member may be installed upside down.

According to the present invention, the operating force can be reliably transmitted to the sickle member. In addition, when the sliding door is strongly closed with the sickle protruding, it is possible to improve the malfunction caused by the sickle colliding with the door pillar, which is convenient.
