[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In addition, the same reference numerals denote the same components or elements throughout the drawings.

[0022] The hanging window according to the present invention is shown in Fig. 1 to Fig. 5, and this hanging window 1 is specifically a small opening and closing window installed in a bathroom or the like, and as shown in Fig. 1, a single window body 2 is in the form of a single sliding window that slides left and right along a wall 50 of the bathroom to open and close an opening 51. In Fig. 1, Fig. 1(a) shows the opening 51 in a closed state, and Fig. 1(b) shows the opening 51 in an open state.

[0023] The hanging window 1 in the illustrated embodiment has a window frame 3 framed in a rectangular shape spanning the wall 50 and the opening 51, and the window body 2 is attached to this window frame 3 in a suspended manner so that it can be opened and closed, and a partition lock 4 is provided on the window body 2 as a locking structure when the window is closed.

[0024] Specifically, the window frame 3 is formed by a rectangular frame of an upper frame rail 3a, a lower frame 3b, a left vertical frame 3b and a right vertical frame 3d, and a pair of running rollers 5, 5 are mounted on the upper frame rail 3a of the window frame 3 so as to be able to roll in the left and right direction, and the left and right upper end portions of the glass frame 6 of the window body 2 are supported in a suspended manner by this pair of running rollers 5, 5.

[0025] The glass frame 6 is formed in a rectangular shape by an upper frame 6a, a lower frame 6b, a left frame 6c, and a right frame 6d, and glass 7 is fitted into this glass frame 6 to form the window body 2. The left and right ends of the upper frame 6a are supported in a suspended manner by the pair of running rollers 5, 5 via support brackets 8, 8, allowing the window body 2 to open and close in the left and right direction.

[0026] Although not specifically shown, the suspended window 1 is appropriately provided with a vibration prevention structure for preventing the window body 2 from shaking depending on the purpose.

[0027] The partition lock 4 is for locking the opening and closing window 1, and as shown in FIG. 1, is provided integrally with the window body 2 and extends in the vertical direction.

[0028] Specifically, as shown in Figures 2 and 3, the partition lock 4 has a lock body 11 housed within an elongated lock case 10 so that it can be moved in the vertical direction, and the lock case 10 is disposed so as to extend linearly in the vertical direction in a portion of the glass 7 adjacent to the left frame 6c of the window body 2.

[0029] The lock case 10 is made up of an interior case member 12 and an exterior case member 13, both of which are made from metal square pipes with a rectangular cross section. In the illustrated embodiment, aluminum square pipes are used to reduce weight.

[0030] As shown in Figure 2, the lock case 10 is arranged in close contact with both surfaces of the glass 7 of the window body 2, with the indoor case member 12 and the outdoor case member 13 sandwiched between them from the indoor side and the indoor side, and extends vertically along both surfaces of the glass 7, and its upper and lower ends are fixed to the upper and lower frames 6a and 6b of the glass frame 6 by appropriate fixing means, respectively, as shown in Figure 1.

[0031] The lock body 11 moves up and down within the lock case 10 to lock and unlock the door, and is specifically built into the interior lock case member 13 of the lock case 10, as shown in Figures 2 and 3.

[0032] As shown in Figures 4 and 5, the lock body 11 is in the form of a rod-shaped body consisting of a lock pin 17, a connecting portion 18 and an operating portion 19 connected together in a linear manner, and has a shape and dimensions that allow it to be slidably incorporated into the indoor lock case member 13.

[0033] The lock pin 17 is provided at the upper end of the lock body 11 and is made of metal to lock and engage with the window frame 3, and is formed integrally with its base, the lock pin holding part 20, which is also made of metal. Correspondingly, when the window body 2 moves to the left and is in the state of Fig. 1(a) in which the opening 51 is closed, a locking hole 21 into which the lock pin 17 enters and engages is provided at the corresponding position of the lock pin 17 in the upper frame rail 3a of the window frame 3.

[0034] The lock pin retaining portion 20 is slidably held within the interior case member 12 and is the portion to which the connecting portion 18 is integrally connected, and for this purpose, a connection step portion 22 to which the connecting portion 18 is connected and connection pins 22a, 22a are provided.

[0035] In addition, the connecting portion 18 is connected to the connecting step portion 22 of the lock pin holding portion 20, and the outer peripheral contour shape when the lock pin holding portion 20 and the connecting portion 18 are joined together is set to have a rectangular cross-section that corresponds to the inner peripheral contour shape of the indoor side case member 12, thereby giving the lock pin holding portion 20 the function of being held slidably within the indoor side case member 12.

[0036] As described above, the connecting portion 18 connects the lock pin 17 and the operating portion 19, and is made of a flat metal plate having the same width dimension as the lock pin holding portion 20 and the operating portion 19, as shown in Figures 4(a) and 4(c).

[0037] In addition, the upper end of the connecting portion 18 is provided with connection holes 18a, 18a into which the connection pins 22a, 22a of the lock pin holding portion 20 are inserted and connected, and the lower end is provided with insertion holes 18b, 18b into which the connecting pins 25a, 25a of the operating portion 19 are inserted.

[0038] The length of the connecting portion 18 is set in accordance with the height of the window body 2 to which it is to be applied. In other words, by appropriately adjusting and setting the length of the connecting portion 18, it can be widely applied to a plurality of types of window bodies 2 having different shapes and dimensions, and even to opening / closing windows 1.

[0039] Furthermore, in relation to this configuration, the lock pin 17 and the operating portion 19, which are components other than the connecting portion 18, can be common parts that can be used for a plurality of types of window bodies 2 and even opening / closing windows 1 having different shapes and dimensions.

[0040] The operating unit 19 is in the form of a metal block and is used to lock and unlock the partition lock 4. This operating unit 19 is provided facing both the indoor and outdoor sides of the lock case 10, and specifically, has a two-part structure consisting of an operating unit main body 24 facing the indoor side and an emergency unlocking operating unit 25 facing the outdoor side.

[0041] The operation unit main body 24 and the emergency unlocking operation unit 25 are structured to be integrally connected by sandwiching the lower end of the connecting portion 18 between them, and for this purpose, connecting holes 24a, 24a are provided in the operation unit main body 24, and connecting pins 25a, 25a are provided on the connecting surface of the emergency unlocking operation unit 25, which are inserted and connected to the connecting holes 24a, 24a.

[0042] Then, the connection pins 22a, 22a of the lock pin holding portion 20 are inserted and joined into the connection holes 18a, 18a at the upper end of the connecting portion 18, so that the lock pin 17 and the connecting portion 18 are integrally connected.

[0043] On the other hand, the lower end of the connecting portion 18 is sandwiched between the operating unit main body 24 and the emergency unlocking operating unit 25, and the connecting pins 25a, 25a of the emergency unlocking operating unit 25 are inserted and connected into the connecting holes 24a, 24a of the operating body 24 while being passed through the insertion holes 18b, 18b of the lower end, thereby integrally connecting the three parts 24, 18, 25 and integrally connecting the connecting portion 18 and the operating unit 19 (24, 25).

[0044] As a result, as shown in FIG. 4, the lock pin 17, the connecting portion 18 and the operating portion 19 are integrally connected in a straight line to form the lock body 11 in the form of a rod-shaped body.

[0045] As mentioned above, the operating unit 19 is arranged facing both the indoor and outdoor sides of the lock case 10, with the lock body 11 in the form of a rod-shaped body being slidably incorporated into the indoor lock case member 13 of the lock case 10, as shown in Figures 2 and 3.

[0046] For this purpose, a long hole-shaped through opening (opening) 30 is provided in the glass 7 of the window body 2, which allows the operating unit 19 to pass from the inside to the outside of the room, guides the vertical movement of the operating unit 19, and determines the range of its vertical movement.

[0047] In addition, corresponding to this through opening 30, the inner walls 12a, 13a of the indoor case member 12 and the outdoor case member 13, which are arranged in contact with both surfaces of the glass 7, are provided with elongated through openings (openings) 31, 32 having the same contour shape as the through opening 30, and the outer walls 12b, 13b of the indoor case member 12 and the outdoor case member 13 facing the inner walls 12a, 13a are provided with operation openings 33, 34 facing the operation surfaces 19a, 19b of the operating unit 19.

[0048] An operation knob 35 is provided integrally with the operation unit body 24 on the operation surface 19a thereof, and this operation knob 35 protrudes from the operation opening 33 into the room so as to be operable up and down with the fingers.

[0049] Meanwhile, an emergency unlocking hole 36 in the form of a small diameter recess is provided on the operation surface 19b of the emergency unlocking operation unit 25. This emergency unlocking hole 36 faces the outside of the room from the operation opening 34, and in the event that an emergency occurs in a room such as the bathroom and unlocking operation cannot be performed from inside the room, an emergency unlocking operation can be performed from outside the room by inserting a thin rod-shaped object such as a pen into this emergency unlocking operation hole 36.

[0050] As described above, the oblong through opening (opening) 30 provided in the glass 7 of the window body 2 and the oblong through openings (openings) 31, 32 provided in the lock case 10 guide the vertical movement of the operating unit 19 and define the range of vertical movement.

[0051] Specifically, the lock body 11 moves up and down within the lock case 10, causing the lock pin 17 to lock and unlock, and this vertical movement of the lock body 11 is achieved by operating the operating portion 19 up and down using the operating knob 35.

[0052] In this case, the vertical movement of the operating portion 19 is guided linearly and smoothly by the left and right side portions of the through openings 30, 31, 32, and the range of the vertical movement is defined by the upper and lower ends of the through openings 30, 31, 32.

[0053] That is, as shown in Figure 1(a), when the window body 2 has moved to the left end and the opening 51 is closed, when the operating part 19 is moved upward by the operating knob 35, the operating part 19 abuts against the upper end of the through openings 30, 31, 32, the lock body 11 reaches the stop position (upper end of movement) of its upward movement shown in Figures 2(b) and 3(b), and when the lock body 11 is at the upper end of movement, the lock pin 17 protrudes upward from the window body 2 and enters and engages with the engagement hole 21 of the window frame 3, entering a locked state.

[0054] On the other hand, for example, when the operating part 19 is moved downward by the operating knob 35 from the locked state so that the operating part 19 abuts against the lower end of the through openings 30, 31, 32, the lock body 11 reaches the stop position (lower end of movement) of its downward movement shown in Figures 2(a) and 3(a), and when the lock body 11 is at the lower end of movement, the lock pin 17 retracts into the window body 2 and the lock is in an unlocked state.

[0055] The operation unit 19 also has a function of maintaining the locked state of the lock body 11. Specifically, the operation unit 19 has a magnetic attraction portion made of a magnetic material.

[0056] In the operating unit 19 of the illustrated embodiment, the emergency unlocking operating unit 25 is a magnetically attracted unit made of magnetic metal, and correspondingly, a permanent magnet (magnet) 37 is attached and fixed at a position in contact with the upper end of the through opening 32 in the outdoor case member 13.

[0057] When the operating part 19 is at the upper end of the movement, the emergency unlocking operating part 25, which is the magnetically attracted part, is simultaneously magnetically attracted to the permanent magnet 37 (see FIG. 2(b)), whereby the lock body 11 resists a falling action due to its own weight and is attracted and maintained in a locked state in which the lock pin 17 is inserted and engaged in the engagement hole 21 of the window frame 3. This locked state is maintained as long as no downward force is applied to the operating part 19.

[0058] On the other hand, when a downward force is applied to the operating unit 19 from the locked state, the magnetic adsorption state by the permanent magnet 37 is released, and the operating unit 19 descends due to its own weight (and the downward force), and the locked state is released (the unlocked state is reached).

[0059] Therefore, when the opening and closing window 1 constructed as described above is, for example, a small hanging type single sliding window installed in a bathroom, a person taking a bath normally closes and locks the window body 2 from the inside of the room once entering the bathroom.

[0060] The locking operation at this time is performed by pulling the window body 2 of the sliding window 1 to the left end to close the opening 51, as shown in Figure 1(a), and then, with the opening 51 closed, moving the operating knob 35 of the partition lock 4 upward from inside the room. As a result, as described above, the lock body 11 of the partition lock 4 moves to the upper end of its range shown in Figures 2(b) and 3(b), and the lock pin 17 enters and engages with the locking hole 21 of the window frame 3, thereby entering the locked state.

[0061] When the person taking a bath finishes, in order to ventilate the bathroom, they unlock the window body 2 from inside the room and pull the window body 2 to the right end to open the opening 51, as shown in FIG. 1(b).

[0062] The unlocking operation at this time is performed by pushing down the operating knob 35 of the partition lock 4 from inside the room to move it downwards when the opening / closing window 1 is in the locked state as shown in Fig. 1(a). As a result, as described above, the lock body 11 of the partition lock 4 moves to the lower end of its range as shown in Fig. 2(a) and Fig. 3(a), and the lock pin 17 is released from its inserted engagement with the engagement hole 21 of the window frame 3 and retracts into the window body 2, thus entering the unlocked state.

[0063] In addition, there may be cases where an emergency occurs to a person taking a bath in the bathroom, such as injury or sudden illness, and the person taking a bath is unable to open the opening / closing window 1, which is locked from the inside of the room, and call for help from outside.

[0064] In the event of such an emergency, a family member or the like can emergency unlock the opening / closing window 1 from outside the room.

[0065] In other words, when the opening and closing window 1 is in the locked state as shown in Figure 1 (a), a family member or the like can insert a thin, rod-shaped object such as a pen into the emergency unlocking operation hole 36 of the emergency unlocking operation unit 25 from outside the room and press down the operation unit 19 to move it downward, thereby unlocking the partition lock 4 in the same way as the unlocking operation from inside the room described above.

[0066] As described above in detail, the partition lock 4 and the opening / closing window 1 of this embodiment provide the unique effects listed below.

[0067] (a) The partition lock 4 is configured so that a lock body 11 equipped with a lock pin 17 that locks and engages with the window frame 3 is built into an elongated lock case 10 that extends in a straight line in the vertical direction on the window body 2 and can be moved up and down. Therefore, the external shape of the lock case 10 is elongated and rod-like, so that it does not obstruct the light gathering area of ​​the window body 2 and has a clean appearance that harmonizes with the shape of the opening and closing window 1 and is also excellent in terms of design.

[0068] (b) The partition lock 4 has a lock body 11 equipped with a lock pin 17 that locks into the window frame 3 and is built into an elongated lock case 10 so that it can be moved up and down. As a result, the number of parts is reduced and the structure is simple and compact, making it particularly suitable for small windows that can be opened and closed, such as those in bathrooms.

[0069] (c) The partition lock 4 is configured such that the lock body 11, which is built into an elongated lock case 10 so as to be movable up and down, is in a locked state with the lock pin 17 protruding upward from the window body 2 when it is at the upper end of its range of movement, and is in an unlocked state with the lock pin 17 retracted into the window body when it is at the lower end of its range of movement, making locking and unlocking operations simple and easy.

[0070] (d) The partition lock 4 has a lock body 11 built into an elongated lock case 10 so that it can be moved up and down. The lock body 11 is in the form of a rod-shaped body consisting of a lock pin 17 provided at the upper end, a connecting portion 18 and an operating portion 19 which are connected together in a straight line. As a result, the lock has a simple structure. By simply setting the length dimension of the connecting portion 18 in accordance with the height dimension of the target window body 2, the lock can be applied regardless of the size of the window body 2, making it highly versatile.

[0071] (e) In addition to the effect of (d) above, of the components of the lock body 11, the lock pin 17 and the operating part 19, excluding the connecting part 18, can be used as common components for window bodies 2 of various shapes and dimensions and even partition locks 4. This, combined with the small number of parts and the simple structure, makes it possible to significantly reduce manufacturing costs and product costs.

[0072] (f) In the hanging window 1 of this embodiment, the partition lock 4 is integrally provided on the window body 2, extending in the vertical direction, so that the effects of the partition lock 4 described above in (a) to (e) are effectively exerted, and a hanging window 1 that is excellent in both structure and design can be provided.

[0073] The above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this embodiment, but various design modifications are possible within the scope of the present invention. For example, in the illustrated embodiment, the partition lock 4 is in the form of an individual device independent of the window body 2, with the lock case 10 being arranged parallel to the vertical frame at a portion of the glass 7 adjacent to the vertical frame of the glass frame 6 in the window body 2 (the left vertical frame 6c in the illustrated case), as shown in Figures 2 and 3, but a configuration in which the partition lock is in the form of a device integrated into the window body 2 can also be adopted. As an example, the lock case 10 is formed from a vertical frame (left vertical frame 6c or right vertical frame 6d) of the glass frame 6 of the window body 3, and the partition lock 4 is integrated into the glass frame 6 to form a device. In this case, for example, the lock case 10 of the partition lock 4 is configured to be formed from the left vertical frame 6a of the glass frame 6. Specifically, it is also possible to adopt a configuration in which the internal cross-sectional structure of the left vertical frame 6c of the glass frame 6 is modified to a structure that functions as the lock case 10, and the lock body 11 is built in there so as to perform locking and unlocking operations. In addition, in the embodiment shown, the means for maintaining the locked state of the partition lock 4 is such that the operating unit 19 is magnetically attracted by a permanent magnet 37 to prevent the lock body 11 from falling under its own weight, but other means that perform a similar function can also be used.One example, although not specifically shown, is the adoption of a structure that prevents the lock body 11 from falling under its own weight using a leaf spring, gasket, etc.

[0074] Furthermore, the partition lock of the present invention can be applied to opening and closing windows other than the suspended windows of the above-mentioned embodiments, and can be applied to opening and closing doors such as single-sliding windows and double-sliding windows, as well as sliding doors and hinged doors other than windows.
