  As shown in FIGS. 1 and 2, the shutter 23 having the locking / unlocking device 21 according to the present embodiment has a pair of rails opposed to each other with an opening 45 of a building such as a house window sandwiched between both edges. The shutter curtain 27 that moves by engaging the portion 25 and opens and closes the opening 45 is provided. At the lowermost end, which is the front end portion of the shutter curtain 27 in the moving direction, a baseboard 29, which is a long, substantially strip-shaped member that is long in the left-right width direction (the arrow X direction in FIG. 2), which is the direction on both sides of the shutter curtain 27 Is provided. Door end members 31 are screwed to both ends in the longitudinal direction of the skirting board 29 on the outdoor side.
[0016]
  An operation bar 33 as an operation unit is provided on the indoor side surface of the skirting board 29. The operation bar 33 is formed in an approximately L-shaped cross section and is a long member that is long in the direction of the arrow X in the drawing along the longitudinal direction of the skirting board 29. As shown in FIG. 3, the skirting board 29 has at least two long holes 35 that are long in the vertical direction (the arrow Y direction in FIG. 3) that is the opening and closing direction of the shutter curtain 27, and are spaced apart in the longitudinal direction of the skirting board 29. It is drilled apart. As shown in FIG. 4, the operation bar 33 is formed with a pair of through holes 37 at the same pitch as the long holes 35. Screws 39 are inserted into the through holes 37 of the operation bar 33. The screw 39 is inserted into the long hole 35 of the skirting board 29, and a plate nut 41 is screwed to the tip. That is, the operation bar 33 is slidable in the vertical direction in the same direction as the opening / closing direction of the shutter curtain 27 (the arrow Y direction in the figure) and is attached to the skirting board 29.
[0017]
  Each of the pair of rails 43 is provided with a locking portion 47 that protrudes toward the opening 45 inside the groove bottom portion corresponding to the lower end of the window portion as shown in FIG. The locking portion 47 is formed in a substantially triangular shape in a front view in which the upper surface is an inclined surface 47a that is inclined downward toward the opening 45 and the lower surface is a horizontal surface 47b. A latch member, which will be described later, provided on the skirting board 29 is locked to the locking portion 47.
[0018]
  A strip-shaped key bar 49, which is a latch member, is provided on the edge 25 that moves in the rail 43 on both sides in the longitudinal direction of the skirting board 29, and the longitudinal direction of the key bar 49 is the longitudinal direction of the skirting board 29 (the arrow in the figure). (X direction). A long hole 51 that is long in the longitudinal direction of the key bar 49 is formed in the base end 49 b of the key bar 49. A support shaft 53 such as a rivet is inserted into the long hole 51, and the support shaft 53 is fixed to the base plate 29. Accordingly, the key bar 49 slides in the direction of the arrow X in the figure, which is the longitudinal direction of the base plate 29, within the range in which the long hole 51 moves relative to the support shaft 53. Thereby, the front end 49a of the key bar 49 can be moved forward and backward from the edge 25.
[0019]
  Note that the amount of movement M by which the key bar 49 advances and retreats is set to be at least greater than the locking height h of the locking portion 47.
[0020]
  The skirting board 29 is provided with a torsion coil spring 55 as an urging means in the vicinity of the base end 49b of the key bar 49. The torsion coil spring 55 always urges the key bar 49 in the protruding direction. ing. Accordingly, when the key bar 49 urged by the torsion coil spring 55 comes into contact with the locking portion 47 by lowering the shutter curtain 27, the key bar 49 receives a reaction force from the locking portion 47 and receives the torsion coil spring 55. After being moved in the retracting direction against the urging force and passing through the locking portion 47, it is again urged by the torsion coil spring 55 and protrudes to be locked to the locking portion 47.
[0021]
  As shown in FIG. 3, one end of a wire 57 that is a flexible wire is stretched around the base end 49 b of the key bar 49. The other end of the wire 57 is connected and fixed to the key bar 49 on the opposite side, for example. Note that the wire 57 may have the other end fixed to the skirting board 29. In this case, a total of two wires 57 are stretched around each key bar 49.
  The skirting board 29 is provided with a pair of support rollers 59 and 59 with the plate nut 41 interposed therebetween. The wire 57 is stretched around the support rollers 59, 59, and the both are stretched around a sleeve 61 that is externally inserted into the screw 39. In addition, the wire 57 is changed in a predetermined direction by stretching an appropriate portion on the guide roller 63.
[0022]
  Therefore, when the operation bar 33 is slid in the upward direction in FIG. 4, tension is generated and the wire 57 moves backward in the direction in which the key bar 49 is pulled into the edge 25.
[0023]
  Next, the operation of the locking / unlocking device 21 thus configured will be described.
  When the shutter curtain 27 is lowered and lowered, and the key bar 49 comes into contact with the inclined surface 47 a of the locking portion 47, the key bar 49 receives the reaction force from the locking portion 47 and the torsion coil spring 55. It moves in the retracting and retracting direction against the urging force. After passing through the locking portion 47, the key bar 49 is again moved in the protruding direction by the urging force of the torsion coil spring 55 and locked to the locking portion 47. Thereby, the shutter curtain 27 will be in the locked state shown in FIG. In this state, even if an external force in the opening direction (upward in FIG. 6) is applied to the shutter curtain 27, the key bar 49 comes into contact with the horizontal surface 47b of the locking portion 47, and the shutter curtain 27 is prevented from opening. The
[0024]
  On the other hand, to release the unlocked state of the shutter curtain 27, that is, to unlock the shutter curtain 27, the operation bar 33 is slid in the opening direction of the shutter curtain 27, that is, upward as shown in FIG. For example, as shown in the figure, the slide of the operation bar 33 is carried out by placing the thumb on the horizontal protruding plate 65 protruding from the upper edge of the skirting board 29 and the other finger on the operation bar 33 and holding it. This can be easily performed by an operation of narrowing the interval. At this time, the operation bar 33 is formed long in the direction of the arrow X in FIG. 2, so that the operation bar 33 can be gripped at an arbitrary position in both the lateral directions of the shutter curtain 27.
[0025]
  When the operation bar 33 is slid upward, as shown in FIG. 7, the sleeve 61 is moved upward along the long hole 35, and the wire 57 stretched between the support rollers 59, 59 is moved upward. Pulled in the direction. Accordingly, tension is applied to the wire 57, and the key bar 49 is moved in the retracting direction against the urging force of the torsion coil spring 55. As a result, the distal end 49a of the key bar 49 is released from the locked state with the locking portion 47, is released from the locking portion 47 and unlocked, and the shutter curtain 27 can be opened.
[0026]
  The shutter curtain 27 that can be opened is opened with a force in the same direction as the unlocking direction of the operation bar 33 by being further lifted upward while the operation bar 33 is slid upward. Become.
[0027]
  That is, in this locking / unlocking device 21, the long material operation bar 33 is provided so that the longitudinal direction thereof is the width direction of the shutter curtain 27, and the operation bar 33 is at an arbitrary position in the left-right width direction of the shutter curtain 27. It becomes possible to release the locked state. Therefore, the unlocking operation can be performed without fully opening the sliding sash window on one side as in the conventional structure in which the swing lever is provided at the longitudinal center of the base plate 29. Further, since the operation bar 33 is configured to be slidable in the same direction as the opening / closing direction of the shutter curtain 27 (the arrow Y direction in the figure), a series of operations for opening the shutter curtain 27 without changing hands. The unlocking and opening of the shutter curtain 27 can be performed by operation.
[0028]
  Further, since the key bar 49 is connected by the wire 57, the device can be configured without using the long key bar 49, and the locking device can be reduced in weight.
[0029]
  Note that the key bar 49 does not necessarily have to be a pair of left and right, as long as the key bar 49 protrudes from at least one edge 25 of the skirting board 29 and the tip 49 a is locked to the locking portion 47 on the rail 43. .
[0030]
  Next, a second embodiment of the shutter locking / unlocking device according to the present invention will be described.

In addition, the same code | symbol is attached | subjected to the member same as the member shown in FIGS. 1-7, and the overlapping description is abbreviate | omitted.
[0031]
  In the locking / unlocking device 71 according to this embodiment, a key claw 73 as a latch member is provided on the edge 25 that moves in the rail 43 of the skirting board 29, and the front / back direction of the skirting board 29 (arrow Z direction (see FIG. 4)). ) Is provided so as to be swingable about a swing shaft 75. The key claw 73 is substantially T-shaped by a strip-like base member 77 that is long in the vertical direction and a claw portion 79 as a tip that protrudes in the horizontal direction from the substantially central portion of the base member 77 in the vertical direction to the edge 25 side. Is formed.
[0032]
  The key claw 73 is disposed in the direction in which the longitudinal direction of the base member 77 is vertical (arrow Y direction in FIG. 8), and the claw portion 79 is in a horizontal direction (arrow X in the figure) from the edge 25 of the skirting board 29. Protruding in the direction). In the claw portion 79, the base member 77 is normally biased by the torsion coil spring 81 and protrudes from the edge portion 25.
[0033]
  A connection pin 83 is fixed to the lower portion of the base member 77. On the other hand, a support plate 85 is projected horizontally on the lower edge of the base plate 29, and a slide plate 87 is slidably mounted on the support plate 85 in the longitudinal direction of the base plate 29 (in the direction of arrow X in the figure). Is placed. A long hole 89 that is long in the vertical direction (arrow Y direction) is formed in the sliding plate 87, and a connecting pin 83 of the key claw 73 is engaged with the long hole 89. That is, the sliding plate 87 is moved along the longitudinal direction (arrow X direction) of the skirting board 29 in accordance with the swing of the key claw 73.
[0034]
  In the key claw 73, the claw portion 79 at the tip protrudes from the edge portion 25 at one oscillating end position which is the oscillating position shown in FIG. 8, and is rotated counterclockwise from the state shown in FIG. Thus, the claw portion 79 at the tip protruding at the other swing end position shown in FIG. 9 is drawn from the edge portion 25 and retracted.

  A long hole 35 is formed in the skirting board 29. The long hole 35 is disposed at a position corresponding to the rear end of the sliding plate 87 when the key claw 73 is disposed at one swing end position. The elongated hole 35 is elongated in a direction perpendicular to the longitudinal direction of the skirting board 29, that is, in the same direction as the moving direction of the shutter curtain 27, and a pin-shaped stopper 91 is inserted in place of the screw 39 described above. ing. The stopper 91 is also fixed to the operation bar 33 in the same manner as the screw 39 described above. That is, when the operation bar 33 is slid in the same direction as the movement direction of the shutter curtain 27 (the arrow Y direction in the figure), the stopper 91 is also moved along the long hole 35.
[0036]
  The stopper 91 is positioned below the long hole 89 so as to abut the rear end of the sliding plate 87 and restrict the sliding of the sliding plate 87 (see FIG. 8). Thereby, the key claw 73 is prevented from swinging in the direction of the other swing end position. Further, the stopper 91 is retracted from a position where the sliding of the sliding plate 87 is regulated by operating the operation bar 33 upward (see FIG. 9).
[0037]
  Note that the upper end 93a of the locking portion 93 in the rail 43 used in the present embodiment is rotatably attached via a shaft 94. Further, a biasing member 95 is disposed on the locking portion 93, and the biasing member 95 biases the locking portion 93 in the counterclockwise direction of FIG. However, the rotation of the locking portion 93 is restricted by the restricting means so as not to protrude beyond a predetermined height. That is, the locking portion 93 can be retracted by resisting the biasing force of the biasing member 95 from the protruding position.
[0038]
  Next, the operation of the locking / unlocking device 71 configured as described above will be described.
