An open portion 37 is formed so as to allow the head to be removed.

  The operation of the locking device A having the above configuration will be described below with reference to FIGS.

(A) Shoji locked state (Fig. 3 (a))
When the shoji W is closed and the lock handle R is in the locked state, the lock pin P is a space 11 in the base piece 10, a long hole 23 in the first link piece 20, and a long hole in the second link piece 30. 33 is engaged near the upper end of 33. In this state, since the lock pin P is located in the narrow portion 25 of the first link piece 20 (and the narrow portion 35 of the second link piece 30), the shoji W is locked. The process in which the lock pin P changes from the unlocked state to the locked state will be described with reference to FIG.

(B) Shoji lock release (Fig. 3 (b))
When unlocking the shoji W, the lock pin P is moved downward together with the interlocking bar B by the unlocking operation of the lock handle R (see the arrow in FIG. 3B). By this movement, the lock pin P is positioned near the lower end of the space 11 of the base piece 10, the long hole 23 of the first link piece 20, and the long hole 33 of the second link piece 30, and the first pin is moved by moving to the lower end. In the link piece 20, the lock pin P is located in the wide portion 24 of the long hole 23 of the first link piece 20. As a result, the first link piece 20 is placed in a state of being released from the lock pin P.

(C) Shoji small opening start (Fig. 3 (c))
When the operator handle H is rotated and the opening of the shoji W is started with the first link piece 20 released from the lock pin P (see the arrow in FIG. 3C), the second link piece 30 is locked. The pin P starts to rotate about the support shaft 31 and the first link piece 20 starts to rotate about the support shaft 21 as the second link piece 30 rotates. Moreover, the 1st link piece 20 and the base piece 10 are comprised so that the lock pin P may be extracted from the opening formed in the long hole, respectively.

(D) Shoji small opening half-open state (Fig. 3 (d))
When the operator handle H is further rotated in a state where the first link piece 20 is released from the lock pin P, the opening of the shoji W is further expanded (see the arrow in FIG. 3D). The first link piece 20 and the second link piece 30 are also rotated in accordance with the opening of the shoji W.

(E) Shoji small opening stop state (Fig. 3 (e))
When the rotation of the operator handle H is further advanced and the opening of the shoji W reaches the specified shoji small opening position (see the arrow in FIG. 3 (e)), the lock pin P is the tip of the narrow portion 35 of the second link piece 30. The position (the position farthest from the support shaft 31) is reached and further movement is prevented. At this time, the first link piece 20 and the second link piece 30 extend linearly, and further rotation by the operator handle H is prevented. Thereby, the small opening state of the shoji W is hold | maintained at the regulation opening degree. Since the restraining force of the shoji in this small opening state is performed between the door tip of the shoji W and the vertical frame F2, even if a strong force acts on the shoji W due to strong wind or the like, the small opening state is stably maintained. The

(F) Shoji small opening lock release (Fig. 3 (f))
When it is necessary to further open the shoji W from the small opening state of the shoji W, the second link piece 30 (the guide piece 36) is held in the hand and provided at the tip position of the narrow portion 35 of the second link piece 30. When the head of the lock pin P is moved to the opening 37 (see the arrow in FIG. 3 (f)), and then the guide piece 36 is moved to the front side (the front side in FIG. 3 (f)), the opening portion 37, the head of the lock pin P is removed. When the hand is released from the second link piece 30 (guide piece 36) with the lock pin P (head thereof) removed from the opening 37, the first link piece 20 is acted upon by the coil spring 22 and the coil spring 32. The second link piece 30 is stacked so as to be folded on the base piece 10. Thereby, since the shoji W becomes the state released from the lock pin P, rotation of the operator handle H can be further advanced, and the shoji W can be expanded to a required opening degree.

(G) Shoji small opening storage (Fig. 3 (g))
In the state where the shoji W is released from the lock pin P, the base piece 10, the first link piece 20 and the second link piece 30 are in a laminated state. , The shoji W is moved in the closing direction (see the arrow in FIG. 3G). By the movement, the head of the lock pin P is guided in contact with the guide piece 36 of the second link piece 30, and the head of the lock pin P is the space 11 of the base piece 10 and the long hole 23 of the first link piece 20. And inserted into the elongated hole 33 of the second link piece 30. The position of the lock pin P at this time is in the state shown in FIG. Therefore, when the lock pin P is moved together with the interlocking bar B by the operation of the lock handle R in the direction opposite to the arrow direction shown in FIG. 3B, that is, when the lock pin P is moved upward, W is in the locked state shown in FIG.

  In the locking device A of the present embodiment, the locking member 1 includes a base piece 10, a first link piece 20, and a second link piece 30, and these base piece 10, first link piece 20, and second link piece 30. Are folded so that they can be folded and connected so as to extend in a straight line, so that the lock device A having a small opening function can be realized by a simple mechanism.

  Moreover, a small opening function can be easily added to the existing joinery T only by replacing with the lock member 1 of this embodiment after removing the existing lock member at the time of reform. At this time, the lock pin P is not only used for locking and unlocking the shoji W, but also used as a pin for maintaining a small opening state. That is, the interlocking bar B can be used without exchanging the existing one.

  Moreover, since the lock member 1 is arranged so as to connect between the door tip of the shoji W and the vertical frame F2, even if a strong force acts on the shoji W due to a strong wind or the like, the small opening state is stably provided. Can be held.

  The lock member 1 is configured so that the link pieces 20 and 30 can be folded and stacked. That is, since the total length of the lock member 1 can be made substantially the same as the total length of the base piece 10, even when the shoji W is small and the length of the heel is short, the small opening limiting mechanism can be easily attached. .
