[0008] [Example] In this embodiment, the opening device is a vertical sliding window 1. (Interior view) Figure 1 is an interior view of a vertical sliding window 1 (opening device). The vertical sliding window 1 (opening device) has a frame 2 into which a shoji screen 3 is fitted so that it can be opened and closed freely. A cam latch handle 4 is attached to a hanging frame 31. When the cam latch handle 4 is opened or closed, the hanging frame 31 engages with the hanging vertical frame 21 and is locked by a locking mechanism described below.

[0009] (Hanging frame) FIG. 2 is an explanatory diagram of the hanging frame 31 and the hanging vertical frame 21 when the cam latch handle 4 is in the open state. Figure 2(A) is a reference diagram showing the cross-sectional direction. Figures 2(B) and 2(C) are both cross-sectional views between D and D, with Figure 2(B) being a cross-sectional view of the hanging frame 31 and Figure 2(C) being a cross-sectional view of the hanging vertical frame 21. The cam latch handle 4 is in an unlocked, open state. As shown in Figure 2(B), a rotation shaft 42 is provided on the hanging frame mounting surface 311 of the hanging frame 31, and the cam latch handle 4 is rotatably supported. One end of the cam latch handle 4 serves as a grip, and the other end serves as a latch 41. The cam latch handle 4 rotates around the rotation shaft 42, and as it rotates, the latch 41 pops out toward the hanging frame vertical frame 21 shown in Figure 2(C). In addition, the fixing plate 35 is attached to the hanging frame visible surface 312 with fixing plate fastening screws 352. The fixing plate 35 is a member to which the lock pin 36 is attached.

[0010] (lock pin and fixing plate) 2(D) is an enlarged view of the inside of the frame A in FIG. 2(B), and shows the fixing plate 35. FIG. 2(D) is a plan view of the fixing plate 35. The fixing plate 35 is a member with a lock pin 36 erected thereon, and has fastening holes 351 on both sides of the lock pin 36 for fixing it to the hanging frame projected surface 312. The fastening holes 351 are formed in an oval shape so that the position of the lock pin 36 can be finely adjusted. The fixing plate fastening screws 352 are driven into the hanging frame projected surface 312 through the fastening holes 351. The tip of the lock pin 36 is an expanded diameter portion 361, the function of which will be described later.

[0011] (Vertical hanging frame) Figure 2(C) is a cross-sectional view of the hanging vertical frame 21. The hanging vertical frame 21 in Figure 2(C) and the hanging frame 31 in Figure 2(B) are closed so that they overlap each other, and the shoji screen 3 of the vertical sliding window 1 (opening device) is in a closed state. A long interlocking rod 6 is attached to the inner peripheral surface 212 of the hanging vertical frame so as to be able to move up and down freely. The lock pin receiver 8 is attached to the surface of the upper end side of the interlocking rod 6 and moves up and down in accordance with the up and down movement of the interlocking rod 6.

[0012] The mechanism for moving the interlocking rod 6 up and down will be described in detail below using other figures.

[0013] (latch) The mechanism for moving the interlocking rod 6 up and down will be described in detail below. Figure 3 is an explanatory diagram of a state in which the shoji screen 3 of a vertical sliding window 1 (opening device) is closed but the cam latch handle 4 is unlocked. Figure 3(A) is a reference diagram showing the direction of the cross-sectional views of Figures 3(B), 3(C), 3(E), and 3(F). As shown in FIG. 3(B), the latch 41 of the cam latch handle 4 is not fitted into the latch receiver 5, and the sliding door 3 is closed but unlocked. As will be described later, the cam latch handle 4 is positioned so that when it rotates around the rotation shaft 42, the latch 41 protrudes toward the latch receiver 5 and fits into it, moving the latch receiver 5 upward.

[0014] (Latch receiver and latch receiver guide) The latch receiver 5 is a component located on the visible surface 211 of the hanging vertical frame, and is housed inside the latch receiver guide 9 attached to the visible surface 212 of the inner periphery of the hanging vertical frame, but is not fixed and moves freely. The latch receiver guide 9 is a component fixed to the visible surface 212 of the inner periphery of the hanging vertical frame in Figure 3(C). The visible surface of the latch receiver guide 9 is provided with a guide groove 92, as shown in Figure 3(B). The guide pin 51 protruding from the latch receiver 5 sticks out of the guide groove 92 and guides the movement of the latch receiver 5. As mentioned above, the latch receiver 5 on the visible surface 211 of the hanging vertical frame is housed in the latch receiver guide 9. In order for the latch 41 to fit freely into the latch receiver 5, the latch receiver guide 9 has a latch receiving opening 93 as shown in Figure 3(C), so that the latch 41 fits into the latch receiver 5 inside the latch receiver guide 9. The latch receiver 5 also has a slider 52 that extends downward. The slider 52 moves in conjunction with the movement of the latch receiver 5. The slider 52 has an engagement pin 53 at its lower end.

[0015] (Main components of the interlocking part) Interlocking portion 7 at the lower end of slider 52 is equipped with a receiving plate 71, which has a U-shaped groove 711 and a bent portion 712. Interlocking portion 7 (receiving plate 71) plays a role in transmitting the movement of slider 52 to interlocking rod 6. The movement of cam latch handle 4 attached to hanging frame facing surface 311 is transmitted to latch receiver 5 on hanging frame facing surface 211, and the movement of latch receiver 5 moves slider 52 on hanging frame inner facing surface 212. The interlocking portion 7 transmits the movement of the slider 52 to the interlocking rod 6 located on the inner peripheral side visible surface 212 of the hanging vertical frame.

[0016] (U-groove and engagement pin) The engagement pin 53 engages with a U-shaped groove 711 of the receiving plate 71. The base of the receiving plate 71 on the opposite side of the U-shaped groove 711 is connected to the interlocking rod 6. The receiving plate 71 is a member having the U-shaped groove 711 that engages with the engagement pin 53 of the slider 52, and the base side is fixed to the interlocking rod 6.

[0017] (Step between the interlocking rod and the slider) As shown in Figure 3(C), the interlocking rod 6 is mounted on the hanging vertical frame 21 together with the slider 52. However, its position is stepped as shown in Figures 3(E) and 3(F). The bent portion 712 in the center of the support plate 71 is provided to accommodate this step, and the bent portion 712 is provided on the support plate 71 along the step.

[0018] (Interlocking part and receiving plate) The receiving plate 71 shown in FIGS. 3(B) and 3(C) that forms part of the interlocking portion 7 is a member that connects the slider 52 provided on the hanging vertical frame 21 and the interlocking rod 6. When the cam latch handle 4 is rotated and the receiving plate 71 moves in accordance with the movement of the engaging pin 53 of the slider 52, the receiving plate 71 faithfully transmits this movement to the interlocking rod 6, causing the interlocking rod 6 to move up and down.

[0019] (Interlocking rod) As shown in FIG. 3(C), the interlocking rod 6 is a member slidably attached to the inner peripheral side visible surface 212 of the hanging vertical frame. As shown in Figures 3(B) and 3(C), the interlocking rod 6 passes through interlocking rod guides 22 attached to the surface of the inner peripheral visible surface 212 of the hanging vertical frame, allowing it to move in the vertical direction. A receiving plate 71 of the interlocking portion 7 is fixed to the lower end of the interlocking rod 6. A lock pin receiver 8 is attached to the upper end of the interlocking rod 6.

[0020] (lock pin) As shown in FIG. 2 and explained above, the lock pin 36 is a member located on the shoji screen 3 (hanging frame 31) side. As shown in Figure 2(D) and Figure 3(B), the lock pin 36 is firmly fixed to the hanging vertical frame visible surface 211 together with the fixing plate 35 by the fixing plate fastening screw 352, and will not move in the vertical direction.

[0021] (Lock pin holder) As mentioned above, the lock pin receiver 8 is attached to the upper end of the interlocking rod 6, which is slidably attached to the inner peripheral visible surface 212 of the hanging vertical frame, and is a member that receives the lock pin 36 as shown in Figures 3(B) and 3(C). FIG. 3(D) is an enlarged view of the lock pin receiver 8 in FIG. 3(C), with the fixed plate 35 that holds the lock pin 36 omitted for clarity. The lock pin receiver 8 can be removed from an opening 82 on the top surface 84 of the lock pin receiver by the action of the lock pin 36 opening the sliding screen 3. The underside of the lock pin receiver 8 forms a restraining portion 83. As shown in FIG. 2(D), the tip of the lock pin 36 forms an expanded diameter portion 361. The width of the restraining portion 83 is such that the expanded diameter portion 361 cannot be removed, and when the lock pin 36 enters the restraining portion 83, the expanded diameter portion 361 catches on the back surface of the lock pin receiver 8, thereby preventing the lock pin 36 from being removed and retaining the lock pin 36 in the restraining portion 83. As will be described later, when the lock pin 36 is positioned in the restraint portion 83, the shoji screen 3 cannot be opened. The user of the vertical sliding window 1 (opening device) can move the lock pin receiver 8 to the open part 82 by rotating the cam latch handle 4 in the direction that disengages the latch 41 from the latch receiver 5, and can also leave the shoji screen 3 closed without locking it by removing the lock pin 36 from the lock pin receiver 8. This leaves it up to the user to decide whether or not to lock the shoji screen 3 when it is closed.

[0022] (Lock pin holder and lock pin) In the explanation so far, the lock pin receiver 8 is located on the hanging vertical frame 21 side, and the lock pin 36 is located on the hanging stile 31 side. The lock pin receiver 8 and the lock pin 36 are components that only need to be engaged with each other, and the attachment relationship can be reversed. In other words, the lock pin receiver 8 may be configured to be located on the hanging stile 31 side, and the lock pin 36 on the hanging vertical frame 21 side. To summarize the above explanations, the hanging vertical frame 21 has a latch receiver 5 that is movable in the longitudinal direction. The hanging vertical frame 21 also has an interlocking rod 6 that moves in the longitudinal direction of the hanging vertical frame 21 in conjunction with the movement of the latch receiver 5. This interlocking rod 6 is provided with either a lock pin 36 or a lock pin receiver 8, and embodiments also include those in which the shoji screen 3 is provided with a cam latch handle 4 and the other of the lock pin 36 or the lock pin receiver 8.

[0023] (Vertical sliding window (opening device) when locked) Figure 4 is an explanatory diagram showing the sliding screen 3 of the vertical sliding window 1 (opening device) closed and the cam latch handle 4 locked. Figure 4(A) is a reference diagram showing the direction of the cross-sectional views of Figures 4(B), 4(C), 4(E), and 4(F). Figure 4(B) is a cross-sectional view taken along the line G-G in Figure 4(A).

[0024] (Latch and latch receiver movement) Comparing the cam latch handle 4 in FIG. 4(B) with that in FIG. 3(B), it can be seen that the cam latch handle 4 is rotated around the rotation axis 42, and the latch 41 is inserted into the latch receiver 5 accordingly. FIG. 4(B) shows the state at the end of the locking operation when the cam latch handle 4 has completely rotated. The process by which the latch 41 and latch receiver 5 move from the state shown in FIG. 3(B) to the state shown in FIG. 4(B) will be described. The cam latch handle 4 rotates around the rotation axis 42 when operated by the user, and the latch 41 begins to enter the latch receiver 5. The latch 41 then continues to enter the latch receiver 5 while pushing the latch receiver 5 upward. The range of movement of the latch receiver 5 is determined by the latch receiver guide 9 shown in FIG. 4(B). The latch 41 fits into the latch receiver 5 through the latch receiving opening 93 of the latch receiver guide 9, and when the latch receiver 5 reaches the end of the latch receiver guide 9, it is blocked by the latch receiver guide 9 and cannot move any further. This represents the end point at which the cam latch handle 4 can rotate during the closing operation.

[0025] (Slider movement) When the cam latch handle 4 is used for locking, the latch receiver 5 moves upward, causing the slider 52, which moves in conjunction with the latch receiver 5, to start moving upward.

[0026] (Movement of interlocking rod) An engagement pin 53 is provided at the lower end of the slider 52, and the engagement pin 53 is connected to the interlocking portion 7. The upward movement of the slider 52 moves the interlocking rod 6 upward via the interlocking portion 7.

[0027] (Movement of lock pin receiver) As shown in FIG. 4(C), as the interlocking rod 6 moves upward, the lock pin receiver 8 provided at the upper end of the interlocking rod 6 moves upward. FIG. 4(D) is an enlarged view of the lock pin receiver 8 in FIG. 4(C), with the fixing plate 35 that holds the lock pin 36 omitted for ease of explanation. At this time, the lock pin 36 does not move at all because it is a member attached to the hanging frame 31. On the other hand, the lock pin receiver 8 moves upward because it is a member provided on the interlocking rod 6 attached to the hanging vertical frame 21. When unlocked, the position of the lock pin receiver 8 relative to the lock pin 36 was within the range of the open section 82, as shown in Figure 3(D), and the shoji screen 3 was able to be opened and closed freely. When locked, the position of the lock pin receiver 8 relative to the lock pin 36 was as shown in Figure 4(D), as the lock pin receiver 8 had moved upward to the position of the restraint section 83, and by engaging, the lock was applied (locked).

[0028] In the embodiment, the cam latch handle 4 is attached to the hanging frame 31. The position of the cam latch handle 4 is not limited to the hanging frame 31, but can be installed anywhere on the shoji screen 3. Similarly, the interlocking rod 6 is not limited to the hanging vertical frame 21, but can be installed anywhere on the frame 2.

[0029] (Summary of Cam Latch Handle Functions) The cam latch handle 4 has a latch 41. When the latch 41 begins to fit into the latch receiver 5, the latch receiver 5 and interlocking rod 6 begin to move. When the latch 41 fits into the latch receiver 5, the shoji screen 3 can be held in the closed position (locked position). At the same time, the latch 41 fits into the latch receiver 5 provided on the hanging vertical frame 21 side, moving the interlocking rod 6 provided on the hanging vertical frame 21 side, and the lock pin 36 and lock pin receiver 8 engage, allowing the vertical sliding window 1 (opening device) to be locked.

[0030] In the embodiment, the opening device is an example of a vertical sliding window 1. The opening device is not limited to the vertical sliding window 1, but can be applied to various windows such as horizontal sliding windows, projection windows, double-hung windows, single-hung windows, inward-opening windows, and outward-opening windows.

[0031] (Effects of the Example) In this embodiment, a simple mechanism consisting of the latch 41 of the cam latch handle 4 and the latch receiver 5 is used as the drive mechanism for locking, which is extremely unlikely to malfunction and is easy to use. In addition, the locking mechanism consisting of the lock pin 36 and the lock pin receiver 8 is located away from the cam latch handle 4 and is not concentrated in one place, so inspection and repair can be performed without any special disassembly, making it easy to use. In addition, the door can be opened, closed, and locked simply by operating the cam latch handle 4, making it easy to use. Furthermore, the mechanism used in this invention is mainly composed of sliding members, and its movement is simple, so it is easy to use and has few malfunctions. Also, the sliding mechanism of the interlocking rod 6 and slider 52 allows the user to understand the interlocking structure without referring to an instruction manual, and even if it does break, it is easy to repair, making it easy to use.

[0032] The above-described embodiments and various aspects can be combined by utilizing each other's techniques, as long as there are no particular contradictions or problems in the purpose, configuration, and the like. [Explanation of symbols]
