Description

The invention disclosed in this application relates to a locking device that can be applied to a window sash in which a shoji installed in a window frame is opened and closed toward the outdoors. More specifically, the present invention relates to a window opening/closing locking device equipped with a mechanism that automatically locks when a shoji is closed, and a window sash and wall structure equipped with the window opening/closing locking device.

There are wall structures that are equipped with window sashes, such as casement windows, sliding windows, projection windows, louver windows, and awning windows, which open and close a shoji screen set into a window frame to the outside. For this type of window sash, a locking device is known that engages a shoji-side engagement member attached to the shoji screen's door frame with a frame-side engagement member attached to the window frame material on the door edge side to hold the shoji screen in a closed position. For example, Patent Documents 1, 2, 3, etc. disclose a window opening/closing locking device (locking device) equipped with a mechanism in which a shoji-side receiving device (engagement frame) with a groove hole bent into an approximately J shape is attached to multiple locations on the projecting part of the door end frame as a shoji-side engaging member for a vertical sliding window, while multiple lock pins (engagement pins) that can be engaged and disengaged with the shoji-side receiving device and a thin interlocking member (lock pin connecting bar) that connects them along the vertical frame on the door end side are attached so that they can move up and down, and when the shoji is closed, a locking/unlocking lever installed on the indoor side of the window frame is operated to move the lock pin up and down to engage with the shoji-side receiving device.

However, the window opening/closing locking device described above is provided separately from the opening/closing mechanism, such as the operator that opens and closes the screen, so when locking the window, a two-step procedure is required: first, the operator must operate the screen to close it, and then the lock/unlock lever of the window opening/closing locking device must be operated to lock it. With this configuration, there is room for improvement in terms of crime prevention, as it is possible that the user may forget to operate the window opening/closing locking device after closing the screen. Therefore, the applicant has invented a window opening/closing locking device that automatically locks when the screen is closed, and has disclosed it in Patent Document 4. The outline of this device will be explained with reference to Figures 1 to 4.

The window opening/closing lock device 1 is incorporated into the window sash of a vertical sliding window, for example, as shown in Figure 1. In this window sash, the window frame 10 and the shoji screen 20 set into the frame are connected via an opening/closing mechanism 30 that includes a friction stay 301, an operator 302, a handle 303, etc.

The window opening/closing lock device 1 is composed of a receiving device 2 attached to the projecting portion of the leading edge frame 201 of the shoji screen 20, a locking pin 3 attached via an interlocking member 4 to the projecting portion of the vertical frame 101 of the window frame 10 that overlaps the leading edge frame 201, and an unlocking mechanism 5 that moves the locking pin 3 and the interlocking member 4 along the material length direction (up-down direction) of the vertical frame 101 to the unlocking side (unlocked position) and a locking mechanism 6 that moves them to the locking side (locked position).

As shown in FIG. 2, the receiving device 2 attached to the shoji screen 20 side has a slot 21 into which the lock pin 3 attached to the vertical frame 101 side engages and disengages. The slot 21 extends linearly along the length of the door end frame 201, and at its lower end is a lock pin delivery opening 22 that opens to the closed side (indoor side) of the shoji screen 20.

The interlocking member 4 is a long, thin material of equal width that is attached to the projected portion of the vertical frame 101 on the door end side via a guide bracket 7 and is held so that it can move up and down in a linear, reciprocating manner along the projected portion of the vertical frame 101. The guide bracket 7 is a short member with an approximately groove-shaped cross section that is attached in a position that overlaps with the receiver 2 when the shoji screen 20 is closed, and a vertically long lock pin guide hole 71 is formed in its front portion to accommodate the lock pin 3 fixed to the interlocking member 4 and move it up and down. In the following explanation, the viewpoint in Figure 2, where the window opening/closing lock device 1 is viewed from inside the window opening, is defined as the "front," and the relative positions of the parts and members and the direction of operation are specified.

An unlocking mechanism 5 that manually moves the interlocking member 4 to an unlocked position is connected near the lower end of the interlocking member 4. The unlocking mechanism 5 comprises a retractable operating lever 51 attached to the interior side of the vertical frame 101 and a crank arm 52 connected to the operating lever 51, and a roughly L-shaped cam groove 53 formed at the tip of the crank arm 52 engages with an operating pin 43 attached to the interlocking member 4. When the operating lever 51 is lifted upward in the illustrated embodiment, the crank arm 52 rotates downward and pushes down the operating pin 43, causing the interlocking member 4 and lock pin 3 to move downward.

The interlocking member 4 is further fitted with a locking mechanism 6 which automatically moves the interlocking member 4 to the locked position when the screen 20 is closed, and is attached to the interlocking member 4 at a distance from the position where the lock pin 3 and the receiver 2 are engaged and disengaged. The locking mechanism 6 is made up of a cam mounting plate 61 as a "cam mounting member" connected to the lower end of the interlocking member 4, a locking/unlocking cam 62 attached to the cam mounting plate 61, a cam receiving bracket 63 as a "cam receiving member" fixed to the vertical frame 101, a tension coil spring 64 as a "biasing member" attached between the cam mounting plate 61 and the cam receiving bracket 63, a trigger mounting plate 81 and a trigger 82 attached to the door frame 201 of the screen 20, etc.

The cam mounting plate 61 is a thin plate-like member that extends vertically with approximately the same width as the interlocking member 4 and has a wider width in the middle. It moves up and down. A lock/unlock cam 62 is attached to the middle portion of the cam attachment plate 61.

As shown in an enlarged view in FIG. 3, the lock/unlock cam 62 includes a pivot base 621 that is approximately circular in front view, a narrow neck 622 that extends downward from the pivot base 621, and an outdoor side from the bottom of the neck 622. and a passive piece 624 that is bent and projects from the indoor side edge of the neck portion 622 toward the inside of the opening surface of the window frame 10. The pivot base 621 is pivotally attached to the cam mounting plate 61 via a rivet 626 or the like, so that the entire locking/unlocking cam 62 is held so as to be able to swing in the indoor/outdoor direction.

The cam receiving bracket 63 has a generally groove-shaped cross section and is screwed to the vertical frame 101 so as to surround the cam mounting plate 61. To avoid interference with these screws, the cam mounting plate 61 is formed with three vertical movement guide holes 611, 612, and 613 extending in the vertical direction. In addition, a tension coil spring 64 is hung near the lower edge of the cam receiving bracket 63 as a biasing member, and the other end of the tension coil spring 64 is hung near the lower end of the cam mounting plate 61. This tension coil spring 64, which is hung on the vertical frame 101 side via the cam receiving bracket 63, applies a biasing force to the cam mounting plate 61 and the interlocking member 4 connected thereto to move them upward.

A window-shaped cam guide 631 is provided on the front of the cam receiver bracket 63, which houses the locking/unlocking cam 62 and moves it up and down from the locked position to the unlocked position. An engaged portion 634 is formed on the outdoor side edge of the lower half of the cam guide 631 for engaging the engaging hook 623 of the locking/unlocking cam 62. The "unlocked position" is when the locking/unlocking cam 62 moves to the lower half of the cam guide 631 and engages the engaging hook 623 with the engaged portion 634, and the "locked position" is when the engaging hook 623 is disengaged from the engaged portion 634 and the locking/unlocking cam 62 moves to the upper half of the cam guide 631.

On the other hand, the trigger attachment plate 81 attached to the shoji 20 side is bent such that its middle portion is perpendicular to the expected portion of the door frame 201, and serves as a trigger holding piece 812. A trigger 82 is pivotally mounted near the top of the trigger mounting plate 81 via a pin 83. The trigger 82 is held such that its outdoor side edge is in contact with the trigger holding piece 812 of the trigger mounting plate 81 so that it can only swing indoors from that position. A pushing piece ("response piece" in Patent Document 1) 821 is formed on the indoor side edge of the trigger 82 and extends perpendicularly to the expected portion of the door frame 201. The trigger mounting plate 81 is positioned such that the pushing piece 821 comes into contact with the passive piece 624 of the locking/unlocking cam 62 that is engaged in the unlocked position when the shoji 20 is closed.

Figures 4 and 5 show the operation of each part when the shoji screen 20 is opened and closed. When the shoji screen 20 is open, as shown in Figure 4(a), the locking/unlocking cam 62 moves to the lower half of the cam guide portion 631, and the engaging hook 623 engages with the engaged portion 634. Therefore, the cam mounting plate 61 to which the locking/unlocking cam 62 is attached, and the interlocking member 4 and lock pin 3 connected thereto are also temporarily fixed at this height (unlocked position).

When the shoji 20 is closed in this state, the pushing piece 821 of the trigger 82 attached to the shoji 20 comes into contact with the passive piece 624 of the locking/unlocking cam 62, as shown in FIG. 4(b). At this time, the receiver 2 attached above the shoji 20 is in a position to receive the lock pin 3 into its lock pin delivery opening 22, as shown in FIG. 2(b). When the shoji 20 is closed a little more, the trigger 82 pushes the locking/unlocking cam 62 indoors, and the engaging hook 623 of the locking/unlocking cam 62 is engaged with the cam guide part 631, as shown in FIG. 4(c). It comes off from the section 634.

Then, as shown in Figures 4(d)-(e), the cam mounting plate 61 is instantly pulled up by the biasing force of the tension coil spring 64. As a result, the interlocking member 4 and lock pin 3 also move upward, and as a result, as shown in Figure 2(a), the lock pin 3 enters the back of the groove hole 21 of the receiver 2, making it impossible to open or close the screen 20. In this way, simply by closing the screen 20, the lock pin 3 engages with the receiver 2 in response to contact between the trigger 82 and the locking/unlocking cam 62, and the screen is automatically locked.

When opening the closed shoji screen 20, the operating lever 51 of the unlocking mechanism 5 is manually operated from the locked state shown in Figure 5 (a) to push down the interlocking member 4. Then, as shown in Figures 3 and 5 (b) to (c), the cam mounting plate 61 connected to the interlocking member 4 also descends, and the locking/unlocking cam 62 moves to the lower half of the cam guide portion 631, engaging the engaging hook 623 with the engaged portion 634. When the interlocking member 4 is temporarily fixed in the unlocked position in this way, the lock pin 3 also comes to the same height as the lock pin delivery port 22 of the receiver 2, so the shoji screen 20 can be opened as is.

In the state shown in FIG. 5(c), the pushing piece 821 of the trigger 82 is located inside the door relative to the passive piece 624 of the locking/unlocking cam 62, but by opening the shoji screen 20, the pushing piece 821 of the trigger 82 comes into contact with the passive piece 624 of the locking/unlocking cam 62 from inside the door. The reaction force lifts the trigger 82, as shown in FIG. 5(d), and moves outside while rotating so as to overcome the passive piece 624.

After the screen 20 is opened as shown in FIG. 5(e), the interlocking member 4 and the lock pin 3 remain temporarily locked in the unlocked position by the lock/unlock cam 62 until the screen 20 is closed again.

According to the window opening/closing lock device 1 configured as described above, the interlocking member 4 attached to the window frame 10 side and temporarily fixed at the "unlock position" can be operated by an operator or the like to close the shoji 20. The lock pin 3 fixed to the interlocking member 4 instantly engages with the receiver 2 attached to the shoji 20, thereby locking the shoji 20. held in state. Therefore, it is possible to prevent a situation where the user forgets to lock the shoji 20 after closing it.

Japanese Patent Application Publication No. 2002-188336 Japanese Patent Application Publication No. 2006-022515 JP 2018-104947 A Patent No. 6977976

Regarding the window opening/closing locking device 1 disclosed in Patent Document 4, the present applicant has focused on the mounting accuracy and engagement state of the locking/unlocking cam in the cam receiving bracket 63, and the interposition at the contact point between the window frame 10 and the shoji 20. Due to factors such as the elasticity of the airtight member, the precision of the construction of the trigger mounting plate 81, and other factors, the degree of closing of the shoji 20 may change or become uneven, which may cause the trigger to push in the lock/unlock cam when the shoji 20 is closed. It has been discovered that the accuracy is reduced and the locking mechanism may not respond reliably. However, the conventional mechanism is not equipped with a means for appropriately adjusting the contact state between the trigger and the lock/unlock cam.

Therefore, the invention disclosed in the present application is an improved window opening/closing method that can suitably maintain the response accuracy of the locking mechanism by adjusting the position (timing) at which the trigger contacts the locking/unlocking cam during the operation of closing the shoji. A locking device is provided. In addition, the present invention provides a window sash that can be opened and closed by the window opening/closing lock device, and a wall structure equipped with the window sash.

In order to achieve the above-mentioned object, the window opening/closing lock device of the invention disclosed in this application has a receiving device attached to the projected portion of the door frame of a shoji screen that is built into a window frame and opened and closed to the outside, and a lock pin that engages and disengages with the receiving device is attached to the projected portion of the window frame that overlaps with the door frame via an interlocking member that moves along the material length direction of the window frame. When the shoji screen is closed, the interlocking member moves to a "locked position" where the lock pin engages with the receiving device to lock the shoji screen, and when the interlocking member moves to an "unlocked position" where the lock pin is removed from the receiving device, the shoji screen can be opened and closed. In this window opening/closing lock device, a biasing force is applied to the interlocking member in a direction that moves it toward the locked position, and when the shoji screen is closed, a pushing force from a trigger attached to the door frame of the shoji screen is applied to the interlocking member. The locking mechanism moves the interlocking member from the unlocked position to the locked position by operating an unlocking operation member attached to the inside of the door from the closed position of the door screen, and the trigger is pivotally attached to a trigger mounting plate attached to the front of the door frame of the door screen via a pin joint so that it can swing to the indoor side. A push piece is provided at the bottom of the trigger to come into contact with a locking/unlocking cam provided on the locking mechanism and push the locking/unlocking cam to the indoor side. An adjustment means is provided at the joint between the trigger and the trigger mounting plate to change the contact position of the push piece against the locking/unlocking cam in the indoor/outdoor direction so that it can be operated from the indoor side.

The adjustment means further includes an adjustment base piece that is located above the pin joint on the trigger mounting plate and protrudes toward the window frame, an adjustment member that is held by the adjustment base piece and moves in the indoor/outdoor direction when operated from the indoor side, and a receiving piece that protrudes from the top of the trigger toward the window frame and faces the adjustment base piece. The adjustment member comes into contact with the receiving piece to restrict the swing range of the pushing piece toward the outdoor side, and the contact position between the pushing piece and the locking/unlocking cam changes according to the movement of the adjustment member in the indoor/outdoor direction.

Furthermore, the adjustment member is configured as a male screw with a head on the indoor side that is screwed into a female screw hole formed in the adjustment base piece.

The window sash of the invention disclosed in this application is characterized as having a window frame and a sliding screen that are locked and unlocked by the window opening and closing locking device described above. The wall structure of the invention disclosed in this application is also characterized as having the window sash described above.

With the window opening/closing lock device configured as described above, the timing at which the trigger's push piece contacts the locking/unlocking cam during the action of closing the door can be adjusted by operating the adjustment means provided at the joint between the trigger and the trigger mounting plate. This adjustment can be easily performed from inside the house, so it is possible to always maintain optimal response accuracy of the locking mechanism, and the window opening/closing lock device can be used safely for a long period of time.

The following describes an embodiment of the invention disclosed in this application with reference to the drawings. Note that in the embodiment described below, components and parts that have substantially the same functions or actions as the conventional window opening/closing lock device 1 (FIGS. 1 to 5) described in the Background Art section are given the same reference numerals, and their description will be simplified.

The window opening/closing locking device 11 according to the invention disclosed in this application is assembled, for example, in a portion A enclosed by a chain double-dashed line in a vertical sliding window shown in FIG. 1, in place of the conventional unlocking mechanism 5 and locking mechanism 6. The opening/closing mechanism 30 for opening and closing the shoji 20 built into the frame of the window frame 10 can be configured by appropriately selecting or combining conventionally known mechanisms, and in the invention disclosed in this application, the detailed configuration thereof is not particularly limited.

The window opening/closing lock device 11 is composed of a receiving device 2 attached to the projected portion of the door end frame 201 of the shoji screen 20, an interlocking member 4 attached via a guide bracket 7 to the projected portion of the vertical frame 101 of the window frame 10 that overlaps the door end frame 201 so as to be movable up and down, a locking pin 3 fixed at a predetermined position of the interlocking member 4, and an unlocking mechanism that moves the locking pin 3 and interlocking member 4 to the unlocking side (unlocked position) along the material length direction (up and down direction) of the vertical frame 101 and a locking mechanism that moves them to the locking side (locked position). The configurations of the receiving device 2, locking pin 3, interlocking member 4, and guide bracket 7 are not significantly different from those described in the Background Art section, but in the invention disclosed in this application, the engagement and disengagement form between the receiving device 2 and the locking pin 3 is not particularly limited.

6 to 10 show the schematic configuration of the unlocking mechanism 50 and the locking mechanism 60, which constitute the main parts of the window opening/closing locking device 11, and their operating states. 6 is a front view of the unlocking mechanism 50 and locking mechanism 60 assembled in the boxed area A of FIG. 1, and FIG. 7 is a cross-sectional view taken along the line BB in FIG. 6. 8 is a perspective view of the main part showing the normal locked state (the state in which the shoji 20 is closed and locked), and FIG. 9 is the main part showing the normal unlocked state (the state in which the shoji 20 can be opened and closed). FIG. 10 is an exploded perspective view showing the assembly structure of the operation box and the operation slider.

The unlocking mechanism 50, which manually moves the interlocking member 4 to the unlocked position, is connected near the lower end of the interlocking member 4. The example unlocking mechanism 50 includes an operation box 54 attached to the vertical frame 101 on the indoor side of the closed position of the shoji screen 20, and an operation slider 55 assembled in the operation box 54 as an "unlocking operation member" that slides up and down.

The operation box 54 is a vertically long box with an opening on the front side, and its main body except for the periphery of the front side is embedded in an opening formed in the projection of the vertical frame 101. The operation box 54 is fixed to the back of the vertical frame 101 by two male screws 541, 542 that penetrate from the front side to the back side at two points on the top and bottom. The operation slider 55 has an operation knob 551 protruding from the middle part in the vertical direction on the front side, and a small block-shaped magnet 56 is fitted on the upper side (lock position side) of the operation knob 551. This magnet 56 is a neodymium magnet or other permanent magnet, and serves as the detection body of the magnetic proximity sensor described below.

Guide plates 57, 57 that facilitate smooth vertical movement are placed on the front side of the operation slider 55 at the top and bottom of the operation slider 55. Approximately half of these guide plates 57 appear and disappear above and below the operation box 54 from the back side of the projection of the vertical frame 101 as the operation slider 55 moves up and down. The upper guide plate 57 also acts to hide the magnet 56 attached to the operation slider 55 so that it is not visible from the outside. The surface of the lower guide plate 57 has an inverted triangular graphic symbol indicating the direction of the unlocking operation. Each guide plate 57 has a screw insertion hole 571 with a larger diameter than the head of the male screws 541, 542 to allow the male screws 541, 542 that secure the operation box 54 to the vertical frame 101 to be attached and detached. After the operation box 54 is fixed to the vertical frame 101, these screw insertion holes 571 are hidden by removable screw covers 58 that are placed on the top and bottom of the operation box 54 from the front side.

A mechanical portion of the operation slider 55 protrudes from the back side of the operation box 54, and an unlocking operation arm 59 is attached to the mechanical portion. This unlocking operation arm 59 is connected to a mechanical part of the operation slider 55 and does not rotate. The unlocking operation arm 59 is a thin plate-like member that extends to the outside through a slit 103 formed in the center portion of the vertical frame 101, and its end is screwed to the lower end of the interlocking member 4. There is. The operation slider 55 and the interlocking member 4 are integrally connected via the unlocking operation arm 59, so that when the operation slider 55 is manually pushed down, the interlocking member 4 and the lock pin 3 are also lowered in conjunction with this. can be done.

A window opening/closing detector 9 incorporating a detection element of a magnetic proximity sensor is attached to the projecting portion of the vertical frame 101 adjacent to the upper side of the operation box 54. This window opening/closing detector 9 detects the contact/separation state of the magnet 56 attached to the operation slider 55, thereby determining whether the interlocking member 4, which moves integrally with the operation slider 55, is in the locked or unlocked position. In this way, the open/closed state of the shoji screen 20 is automatically detected, and the detection signal is sent to a specified security device, etc., thereby improving crime prevention.

In the illustrated embodiment, the unlocking operation arm 59 is arranged at an angle when viewed from the front, but the extension direction of the unlocking operation arm 59 can be designed appropriately depending on the relative relationship between the mounting position of the operation box 54 and the screw fastening position to the interlocking member 4. In addition, the unlocking mechanism 5 (see Figure 2) that uses the operating lever 51 and crank arm 52 explained in the Background Art section can also be used as an unlocking mechanism that manually pushes down the interlocking member 4. In this unlocking mechanism 5, the operating lever 51 corresponds to the "unlocking operation member", and the crank arm 52 essentially functions as the unlocking operation arm 59.

A locking mechanism 60 is provided below the interlocking member 4 to automatically move the interlocking member 4 to the lock position when the shoji 20 is closed. The locking mechanism 60 includes a cam mounting plate 61 as a "cam mounting member" that is arranged below the interlocking member 4 and moves up and down along the vertical frame 101, a locking/unlocking cam 62 attached to the cam mounting plate 61, and a vertical frame 101. A cam receiving bracket 63 as a "cam receiving member" fixed to the cam receiving bracket 63, a tension coil spring 64 as a "biasing member" attached between the cam mounting plate 61 and the cam receiving bracket 63, and a tension coil spring 64 attached to the shoji 20 side. The trigger mounting plate 810, the trigger 820, and the like are included.

The cam mounting plate 61 is a member that is substantially the same as that described in the Background section with reference to Figures 2 and 3, and the shape and swinging form of the locking/unlocking cam 62 attached to its middle part are also the same as in the conventional case. However, in the invention disclosed in this application, the upper end of the cam mounting plate 61 is not connected to the lower end of the interlocking member 4, but is held so that it can be brought into and out of contact with the lower end of the interlocking member 4.

The cam receiving bracket 63 is also substantially the same as that described in the Background Art section with reference to Figures 2 and 3, and the shape of the cam guide 631 formed on its front portion, the engagement form of the locking/unlocking cam 62 with the cam guide 631, the action of the biasing member (tension coil spring 64) attached between the cam receiving bracket 63 and the cam mounting plate 61, etc. are the same as in the conventional case. However, in the invention disclosed in this application, the cam receiving bracket 63 is not directly screwed to the vertical frame 101. The cam receiving bracket 63 has an L-shaped cross section rather than a groove-shaped cross section, and its front portion is connected only to the cam mounting plate 61 via a rivet 65 that slidably engages with the up-down movement guide holes 612, 613 formed in the cam mounting plate 61.

The cam receiver bracket 63 has a support bracket 66 that extends toward the interior of the room and is connected to the indoor side edge of the front part of the bracket 63 by a fixing means such as a screw. The support bracket 66 extends to the rear side of the operation box 54 through a slit 103 formed in the front part of the vertical frame 101, and is fixed to the vertical frame 101 together with the operation box 54 by a lower male screw 542 that fixes the operation box 54 to the vertical frame 101. In other words, the single male screw 542 that fixes the operation box 54 to the vertical frame 101 constitutes a "cam receiver fixing means" for fixing the cam receiver bracket 63 to the vertical frame 101 via the support bracket 66. By adopting such a cam receiver fixing means, the base point for holding the cam receiver bracket 63 in a predetermined position can be moved indoors from the closed position of the shoji screen 20.

In the window opening/closing locking device 11 configured as described above, even if the locking mechanism 60 malfunctions while the shoji 20 is closed, the locked state can be released by the following procedure.

Step 1: In the locked state, the operation slider 55 is in the raised position. Furthermore, the cam mounting plate 61 and the locking/unlocking cam 62 are also held in the raised position by the biasing force of the tension coil spring 64 with respect to the cam receiving bracket 63, which is fixed in a fixed position regardless of the locked/unlocked state. In this state, first remove the screw cover 58 on the lower side of the operation box 54 as shown in FIG. 11. Then, the head of the lower male screw 542 can be seen in the screw insertion hole 571 of the lower guide plate 57, so loosen and remove the male screw 542.

Step 2: When the lower male screw 542 constituting the cam receiver fixing means is removed, as shown in FIG. Along with 63, it slipped down several centimeters due to its own weight. At this time, the cam mounting plate 61 and the locking/unlocking cam 62, which are held in the raised position with respect to the cam receiving bracket 63, also descend together with the cam receiving bracket 63. As a result, the upper end of the cam mounting plate 61 separates from the lower end of the interlocking member 4.

Step 3: When the cam mounting plate 61 moves away from the interlocking member 4, the upward biasing force applied to the interlocking member 4 in the locked state disappears, and the unlocking mechanism 50 can be operated freely. Therefore, as shown in FIG. 13, when the operation slider 55 is manually pushed down, the interlocking member 4 is also lowered and moved to the unlocked position. This makes it possible to push open the shoji 20 from the indoor side. In other words, the lower male screw 542 fixing the operation box 54 to the vertical frame 101 functions as a member for forcibly releasing the cam receiver fixing means in an emergency due to its ease of attachment and detachment. Note that, instead of the exemplified male screw, it is also possible to employ mechanical means that can be easily attached and detached by, for example, an appropriate engagement/disengagement mechanism or clamping mechanism as the cam receiver fixing means.

When the shoji 20 is opened, the entire locking mechanism 60 on the window frame 10 side can be easily removed by pulling it out to the outside, so the components of the removed locking mechanism 60 are repaired or replaced as appropriate. Insert the ejecting bracket 66 of the locking mechanism 60 whose function has been restored into the slit 103 of the vertical frame 101 from the outdoor side, align the cam receiving bracket 63 appropriately, and fix the ejecting bracket 66 to the operation box 54 and the vertical frame 101. If it becomes available again. In this way, the window opening/closing lock device 11 can be used safely for a long period of time.

Further, as a member on the shoji 20 side constituting the locking mechanism 60, a trigger 820 is attached to the door frame 201 of the shoji 20 via a trigger attachment plate 810. The locking mechanism 60 described above is activated by the trigger 820 pushing the locking/unlocking cam 62 when the shoji 20 is closed. FIG. 14 shows the configuration of a trigger mounting plate 810 and a trigger 820 employed in the window opening/closing lock device 11 of the invention disclosed in this application. The main part of the invention described in the claims of the present application is that a means for adjusting the contact position between the trigger 820 and the locking/unlocking cam 62 is provided at the connecting portion between the trigger 820 and the trigger mounting plate 810. It is in.

The trigger mounting plate 810 is a thin plate-like member that is approximately U-shaped when viewed from the front, and includes a fixing piece 811 that extends outdoors from two locations above and below the side edge on the outdoor side, and a fixing piece 811 that extends from the top and bottom of the side edge on the indoor side to the door frame 201. The adjusting base piece 814 is bent so as to be perpendicular to the expected portion of the vertical frame 101 and protrudes toward the vertical frame 101 side. Each fixing piece 811 is formed with an elongated fixing hole 813 extending in the indoor/outdoor direction, and the trigger attachment plate 810 is screwed to the expected part of the door frame 201 using this fixing hole 813. By making the fixing hole 813 a long hole, the fixing position of the trigger mounting plate 810 can be roughly adjusted in the indoor/outdoor direction according to the position of the cam receiving bracket 63 attached to the vertical frame 101 side and the closing condition of the shoji 20. I can do it.

The adjustment base piece 814 has a female threaded hole penetrating in the indoor-outdoor direction, and a male screw 84 serving as an "adjustment member" is screwed into the female threaded hole from the indoor side. With the shoji 20 slightly open, the head of the male screw 84 located on the indoor side can be turned with a screwdriver or the like from the indoor side.

A pin node using a flat-headed pin 83 is provided slightly above the middle part of the trigger mounting plate 810, and a trigger 820 is pivotally attached to this pin 83 so as to swing in the indoor/outdoor direction. It is kept moist. The trigger 820 includes a swinging part 822 that is pivotally connected to a pin 83 and has a generally trapezoidal shape when viewed from the front, and a pushing part 823 that has a generally rectangular shape when viewed from the front and extends from the lower part of the swinging part 822 toward the indoor side. It is a thin plate-like member. A push piece 821 is formed on the indoor side edge of the push part 823 and is bent so as to be perpendicular to the projection of the door frame 201 and extends toward the vertical frame 101 side. When the shoji 20 is closed, this pushing piece 821 comes into contact with the passive piece 624 of the locking/unlocking cam 62 that is engaged in the unlocked position, pushes the locking/unlocking cam 62 indoors, and the locking/unlocking cam 62 is pushed into the room. Move to lock position.

A receiving piece 824 is formed at the upper part of the indoor side edge of the swinging part 822 and is bent so as to be perpendicular to the prospective part of the door frame 201 and projects toward the vertical frame 101 side. This receiving piece 824 is arranged on the outdoor side of the adjustment base piece 814 of the trigger mounting plate 810 so as to face the adjustment base piece 814. The tip of the male screw 84 screwed into the female screw hole of the adjustment base piece 814 comes into contact with the receiving piece 824, thereby restricting the swing range of the trigger 820 toward the indoor side. By turning this male screw 84 to move it indoors and outdoors and changing its extension to the outdoors, the position where the push piece 821 of the trigger 820 contacts the locking/unlocking cam 62 (during the operation of closing the shoji 20) The timing at which the trigger 820 pushes the locking/unlocking cam 62 can be adjusted steplessly.

As described above, the window opening/closing locking device 11 according to the invention disclosed in this application includes the adjustment base piece 814 provided on the trigger mounting plate 810 and the adjustment member ( It is equipped with an adjustment means including a male screw 84) and a receiving piece 824 provided on the trigger 820 side and abutting the adjustment member, so that when the shoji 20 is closed, the trigger 820 engages the locking/unlocking cam. The timing of pressing 62 can be finely adjusted by operating from the indoor side. Therefore, the response accuracy of the locking mechanism 60 during locking and unlocking and the sealing performance between the window frame 10 and the shoji 20 can be easily optimized.

Although the embodiment of the invention disclosed in this application has been illustrated above, the technical scope of this invention should not be interpreted as being limited by the illustrated embodiment, but should be interpreted conceptually based on the claims. When implementing the invention disclosed in this application, it is possible to appropriately modify the shape, material, arrangement, and connection of the members constituting each part of the device within the range in which substantially the same operation and effect as the illustrated embodiment can be obtained. (For example, in the illustrated embodiment, a male screw 84 is used for the "adjustment member", but instead of this male screw 84, an appropriate position adjustment mechanism using a stepped pin, eccentric cam, dial, etc. can be used. In addition, the direction in which the adjustment member is operated and moved is not limited to the strict perpendicular direction to the shoji screen, but is broadly included up to an inclination of 45 degrees up, down, left, right, and so on with respect to the perpendicular direction to the shoji screen, as long as it does not interfere with operation from the indoor side.)

For the sake of simplicity, in this specification and claims, the direction outside the opening of the window frame is described as the "indoor/outdoor direction," the side on which the shoji screen is opened is described as the "outdoor side," and the side on which it is locked is described as the "indoor side." However, if the window frame is installed in an indoor space, for example, outdoor/indoor should be interpreted as having the above meaning.

The invention disclosed in this application can be widely used not only for vertically sliding windows as illustrated, but also as a locking/unlocking device for windows that adopt other opening/closing modes.
