(First embodiment)
1. Outline of Smoke Exhaust Window Device In this embodiment, a window lock device according to the present invention is applied to a smoke exhaust window device. 1 includes at least a window frame 3, a shoji 5 and the like. The window frame 3 is a frame body that borders the outer edge of the window opening provided in the building. The window frame 3 according to the present embodiment is configured in a rectangular shape.

  The shoji 5 is connected to the window frame 3 so as to be displaceable. The shoji 5 can be displaced between a closing position for closing the window opening and an opening position for opening the window opening. Note that the shoji 5 is swingably connected to the window frame 3 via one or a plurality of hinges 7. The two hinges 7 connect the lower end frame 3 </ b> A of the window frame 3 and the lower end crosspiece 5 </ b> A of the shoji 5.

2. 2. Window Lock Device 2.1 Outline of Window Lock Device The window lock device 10 is a device for disabling the shoji 5 in a state where the shoji 5 is held in the closed position. The window locking device 10 engages with a striker 9 provided on the shoji 5 so as to be hooked, thereby disabling the shoji 5 (see FIG. 2).

2.2 Details of window locking device <Structure of window locking device>
As shown in FIG. 3, the window locking device 10 includes at least a latch 11 and an unlocking member 12. The latch 11 is a fastener that swings and displaces between an engagement position (see FIG. 4) that can be engaged with the striker 9 and a non-engagement position (see FIG. 6) that is separated from the engagement position.

  The latch 11 is rotatably supported by a support shaft 14 that passes through the latch 11. The support shaft 14 is attached to the main body bracket 15. The main body bracket 15 is provided with support portions 15A and 15B that support one end side in the axial direction and the other end side in the axial direction of the support shaft 14.

  The main body bracket 15 is fixed to the mounting bracket 16 with at least two fasteners (in this embodiment, P screws 16A and 16B). The mounting bracket 16 is a mounting bracket for fixing the main body bracket 15, that is, the window locking device 10 to the window frame 3.

  The P screw 16A is attached to one end side of the main body bracket 15 in the direction of displacement of the unlocking member 12 (left and right direction in FIG. 4). The P screw 16 </ b> B is attached to the other end side of the unlocking member 12 in the displacement direction of the main body bracket 15.

  As shown in FIG. 5, the latch 11 always receives an elastic force from the first spring 17A. The first spring 17A exerts an elastic force that holds the latch 11 in the engaged position. For this reason, when the latch 11 is displaced to the non-engagement position, the amount of elastic deformation of the first spring 17A increases as compared with the case where the latch 11 is in the engagement position (see FIG. 7).

  The first spring 17A according to this embodiment is a torsion coil spring. The support shaft 14 passes through the coil portion of the first spring 17A. One end of the first spring 17A is locked to the latch 11. The other end of the first spring 17A is locked to one of the support portions 15A and 15B.

  The unlocking member 12 is a member for displacing the latch 11 from the engagement position to the non-engagement position. The unlocking member 12 can be displaced in a direction parallel to the direction from the engagement position side to the non-engagement position side (hereinafter referred to as a displacement direction). The “displacement direction” is, for example, a direction parallel to the direction from the right side to the left side on the paper surface of FIG.

  That is, the unlocking member 12 is provided with an engaging portion 12A (see FIG. 3) with which the latch 11 can be engaged. When the unlocking member 12 is displaced to the non-engagement position side in the displacement direction, the engaging portion 12A engages with the engaged portion 11A of the latch 11 as shown in FIG.

  For this reason, when the unlocking member 12 is displaced toward the non-engagement position in the displacement direction, the latch 11 swings and displaces from the engagement position to the non-engagement position in conjunction with the displacement. When the unlocking member 12 is displaced toward the engagement position in the displacement direction, the latch 11 is returned to the engagement position by the elastic force of the first spring 17A (see FIG. 5).

  The two long holes 12B shown in FIG. 3 constitute a guide portion that guides the displacement of the unlocking member 12 in cooperation with the two guide pins 12C. The major axis direction of each elongated hole 12B is parallel to the displacement direction. Each guide pin 12C is in sliding contact with the inner peripheral surface of each elongated hole 12B. Each guide pin 12C is fixed to the main body bracket 15.

  As shown in FIG. 6, the unlocking member 12 always receives an elastic force from the second spring 17B. The second spring 17B exhibits an elastic force that displaces the unlocking member 12 from the non-engagement position side to the engagement position side.

  And the unlocking member 12 is extended in the direction parallel to the said displacement direction, as shown in FIG. Of the unlocking member 12, the wire connecting portion 13 is provided on one end side (left side in the drawing) in the extending direction. A connecting portion 12D with the second spring 17B is provided on the other end side (right side in the drawing) of the unlocking member 12 in the extending direction.

  The wire connection part 13 is a site | part to which the wire 18 for unlocking is connected, as shown in FIG. The wire connecting portion 13 is located at a position shifted from the latch 11 in a direction parallel to the displacement direction. The unlocking wire 18 is operated via a manual or electric operating device (not shown).

<Activation of window locking device>
A force (hereinafter referred to as an opening force) for displacing the shoji 5 toward the opening position is always acting on the shoji 5. Note that the opening force is exhibited by an opening device such as a sty damper (not shown). When the shoji 5 is in the closed position, as shown in FIG. 4, since the striker 9 and the latch 11 are in the engaged state, the closed state is maintained.

  When the unlocking wire 18 is operated and the unlocking member 12 is displaced to the non-engagement position side, the engagement between the striker 9 and the latch 11 is released as shown in FIG. For this reason, the striker 9 is separated from the latch 11 together with the shoji 5 by the opening force exerted by the stay damper (see FIG. 7).

  When the unlocking wire 18 is operated, the amount of elastic deformation of the first spring 17A and the second spring 17B increases due to the operating force (tension) of the unlocking wire 18. When the operation force of the unlocking wire 18 disappears, as shown in FIG. 5, the unlocking member 12 returns to the engagement position side by the elastic force of the second spring 17B, and the elasticity of the first spring 17A. The latch 11 is returned to the engaged position by the force.

3. Features of the Window Lock Device According to the Present Embodiment When the window lock device 10 according to the present embodiment is mounted on the smoke evacuation window device 1, the displacement direction of the unlocking member 12 intersects or is orthogonal to the depth direction. Direction (in this embodiment, the left-right direction in FIG. 4). For this reason, as shown in FIG. 4, the wire connecting portion 13 is located at a position shifted in the left-right direction with respect to the latch 11.

  Therefore, as compared with the window locking device provided at a position where the wire connecting portion 13 is shifted in the depth direction (the vertical direction in FIG. 4) with respect to the latch 11, the depth dimension can be reduced. The locking device 10 can be obtained.

  The window locking device 10 has a first spring 17A that exerts an elastic force that holds the latch 11 in the engaged position, and an elastic force that displaces the unlocking member 12 from the non-engaged position side toward the engaged position side. And a second spring 17B to be exerted.

  Thereby, compared with the case where the one spring which combines the function of the 1st spring 17A and the function of the 2nd spring 17B is employ | adopted, the locking device 10 for windows which can reduce the depth dimension can be obtained.

  That is, when the unlocking wire 18 is displaced, a resistance force that prevents the operation (displacement) of the unlocking wire 18 is generated. For this reason, the elastic force which the 2nd spring 17B exhibits becomes larger than the said resistance force.

  Therefore, in this embodiment, the elastic coefficient of the second spring 17B is larger than the elastic coefficient of the first spring 17A. For this reason, if the first spring 17A is a spring having both the function of the first spring 17A and the function of the second spring 17B, the first spring 17A has to be enlarged.

  When the first spring 17A increases in size, the depth dimension increases in response to the increase in size. On the other hand, in the present embodiment, the second spring 17B that opposes the resistance force is a different spring from the first spring 17A that swings the latch 11.

  Therefore, in this embodiment, since the enlargement of the first spring 17A is suppressed, it is possible to obtain the window lock device 10 capable of reducing the depth dimension. In addition, since the 2nd spring 17B is a coil spring which has a central axis parallel to the displacement direction of the unlocking member 12, the influence which enlargement of the 2nd spring 17B has to enlargement of a depth dimension is small.

In the window locking device 10 according to the present embodiment, the mounting position of the main body bracket 15 with respect to the mounting bracket 16 can be reversed left and right (see FIG. 8).
For this reason, the window locking device 10 according to this embodiment can be applied to the window locking device 10 in which the mounting position of the main body bracket 15 with respect to the mounting bracket 16 is reversed left and right. That is, the window locking device 10 according to the present embodiment can be used for both a left-handed window locking device and a right-handed window locking device.
