[0008] Hereinafter, an embodiment of the casement window 1 according to the present invention will be described with reference to the drawings. In the following explanation, the same symbols in different figures indicate parts with the same function, and redundant explanations in each figure will be omitted where appropriate.

[0009] In this embodiment, as shown in Figure 1, the casement window 1 is a sliding window in which the vertical frame on one side (left side in the illustration) of the framed frame body 30 is designated as the hinge vertical frame (door end frame) 3a, and this hinge vertical frame (door end frame) 3a is supported by the frame 2. The casement window 1 in the present invention is not limited to a sliding window, but may have any structure in which a sash 3 is supported by a frame 30 and a panel 31.

[0010] (Basic structure of a casement window) The basic structure of the casement window 1 installed in the structural opening a1 of the structural frame a will be explained. As shown in Figure 1, the casement window 1 comprises a frame 2 and a sash 3 that is rotatably supported within the frame 2. Frame 2 is formed by surrounding it on all four sides with left and right vertical frames 2a and 2b, an upper horizontal frame 2c, and a lower horizontal frame 2d, and the shoji screen 3 is supported on the inner circumference of frame 2.

[0011] As shown in Figures 1 to 4, the shoji screen 3 is framed by a frame body 30 which has a hinge-end vertical frame (door-end frame) 3a, a door-end vertical frame (door-end frame) 3b, an upper horizontal frame (upper frame) 3c, and a lower horizontal frame (lower frame) 3d, with the panel 31 supported via setting blocks 4 and spacers 5. It is designed to open and close by rotating around pivot shafts 30a provided above and below the hinge-end vertical frame (door-end frame) 3a.

[0012] As shown in Figures 2 to 4, the frame 30 has trim pieces 3e attached to the inner circumference of the interior-facing visible surface 301 of the upper horizontal frame (upper frame) 3c, the hinge vertical frame (end frame) 3a, and the door edge vertical frame (door edge frame) 3b, which hold down the panel 31. Reference numeral 30f denotes a pre-attached bead, which is attached to the exterior surface 302 of each frame. Reference numeral 31f denotes a retrofit bead, which is attached to the inside of the trim strip 3e attached to the interior surface 301 of the hinge vertical frame (door end frame) 3a, door edge vertical frame (door edge frame) 3b, and upper horizontal frame (upper frame) 3c, and to the interior surface 303 of the lower horizontal frame (lower frame) 3d. Before the installation of the trim piece 3e, as shown in Figure 7, a clearance s is secured between the lower end of the interior-facing surface 301 of the upper horizontal frame (upper frame) 3c and the upper end of the fitted panel 31, allowing the insertion block 51 of the spacer 5 to be inserted. In other words, since clearance s is secured on the indoor side, the insertion of the insertion block 51 can be performed from the indoor side.

[0013] As shown in FIGS. 1, 2, and 4, the setting block 4 is attached to the inner peripheral side surfaces 320 of the lower horizontal frame (lower frame) 3d, the hanging-end vertical frame (door-end frame) 3a, and the door-tip vertical frame (door-tip frame) 3b. The attached setting block 4 is positioned between the outer peripheral side surface 310 of the panel 31 and abuts against the inner peripheral side surface 320 and the outer peripheral side surface 310 without any gap. As shown in FIG. 3, the spacer 5 is disposed in a gap s1 formed between the inner peripheral side surface 321 of the upper horizontal frame (upper frame) 3c and the outer peripheral side surface 311 at the upper end of the panel 31. The upper and lower surfaces of the disposed spacer 5 abut against the inner peripheral side surface 321 and the outer peripheral side surface 311 without any gap, respectively. That is, the panel 31 fitted into the frame body 30 is supported in a stationary state within the frame body 30 by the setting block 4 and the spacer 5. Thus, the movement of the panel 31 due to its own weight or the opening and closing of the shoji 3 is prevented, and the rattling of the panel 31 is also prevented.

[0014] (Configuration of the setting block) The setting block 4 is formed in a rectangular parallelepiped shape from a hard synthetic resin material such as EPDM-S (ethylene propylene rubber) or CR (chloroprene rubber), for example. As shown in FIG. 1, it is disposed near the lower horizontal frame (lower frame) 3d at the lower part of the hanging-end vertical frame (door-end frame) 3a, near the hanging-end vertical frame (door-end frame) 3a of the lower horizontal frame (lower frame) 3d, and near the upper horizontal frame (upper frame) 3c at the upper part of the door-tip vertical frame (door-tip frame) 3b, respectively. The panel 31 is placed on the setting block 4 disposed on the lower horizontal frame (lower frame) 3d. The setting blocks 4 disposed on the hanging-end vertical frame (door-end frame) 3a and the door-tip vertical frame (door-tip frame) 3b support the panel 31 from the left and right and from below by abutting against the left and right outer peripheral side surfaces 310 of the panel 3;

[0015] (Configuration of the spacer) As shown in FIGS. 1 to 3, the spacer As shown in FIG. 3, the spacer 5 includes a base block 50 attached to the inner peripheral side surface 321 of the upper horizontal frame (upper frame) 3c at the factory, and an insertion block 51 inserted in the expected direction into the gap s2 between the inner peripheral side surface 501 of the base block 50 and the outer peripheral side surface 311 of the panel 31.

[0016] The base block 50 and the insertion block 51 may be formed to have substantially the same width and substantially the same length in the insertion direction, or may have different widths and lengths from each other. The thicknesses of the base block 50 and the insertion block 51 are such that when the two are stacked vertically, the thickness is substantially the same as or slightly smaller than the vertical width of the gap s1. Also, the thickness of the insertion block 51 is substantially the same as or slightly smaller than the vertical width of the gap s2, so that it can be easily inserted into the gap s2.

[0017] The base block 50 is, for example, formed into a substantially rectangular parallelepiped shape from the same material as the setting block 4 and is attached to the inner peripheral side surface 321 of the upper horizontal frame (upper frame) 3c. The insertion block 51 is, for example, formed from a hard synthetic resin material such as ABS resin. As shown in FIGS. 3 and FIG. 5, the end on the insertion direction side (outdoor side) is formed as a wedge portion 510 that is substantially wedge-shaped in side view, and the portion other than the wedge portion 510 is formed as an insertion portion 511.

[0018] As shown in FIGS. 3 and FIGS. 5(a)(c), the wedge portion 510 is formed such that in side view, the upper and lower surfaces narrow at the same angle from the insertion portion 511 toward the tip in the insertion direction. Also, as shown in FIG. 5(c), in plan view, the wedge portion 510 is formed such that both ends in the width direction narrow at the same angle from the insertion portion 511 toward the tip.

[0019] The insertion portion 511 has contact portions 5110 formed above and below it, which come into contact with the inner circumferential surface 501 of the base block 50 and the outer circumferential surface 311 of the panel 31 when the insertion block 51 is inserted into the gap s2. As shown in Figures 5(a) and 5(d), the contact portion 5110 consists of multiple (four in the illustration) protrusions with rounded tips, arranged in parallel at regular intervals along the width direction of the insertion portion 511, and extending over its entire length along the insertion direction of the insertion portion 511. The contact portion 5110 is the same shape and arrangement as the upper and lower surfaces of the insertion portion 511.

[0020] Such a spacer 5 is composed of two members: a base block 50 and an insertion block 51. The insertion block 51 is inserted into the gap s2 between the inner circumferential surface 501 of the base block 50 and the outer circumferential surface 311 of the panel 31 from the interior side in the direction of depth, thereby being positioned in the gap s1. Since the insertion block 51 has a thickness smaller than the vertical width of the clearance s (see Figure 7), it is easy to insert the insertion block 51 into the gap s2. Furthermore, the thickness of the base block 50 and the insertion block 51 is the same as or slightly less than the vertical width of the gap s1 when they are stacked on top of each other. Therefore, the spacer 5 is inserted into the gap s1 with almost no gap, and the inserted spacer 5 does not press the panel 31 with excessive force.

[0021] The insertion block 51 has a wedge portion 510 at its tip, making it easy to insert into the gap s2. Furthermore, since the contact portion 5110 of the insertion portion 511 consists of multiple protrusions with rounded tips, the area of ​​the contact portion 5110 that contacts the inner circumferential surface 501 of the base block 50 and the outer circumferential surface 311 of the panel 31 can be reduced. Moreover, since the longitudinal direction of the protrusions is aligned with the insertion direction, the insertion resistance when inserting the insertion block 51 into the gap s2 can be reduced. Furthermore, the insertion block 51 has a wedge portion 510 that tapers at the same angle from the insertion portion 511 toward the tip in the insertion direction on both its upper and lower surfaces, and the contact portion 5110 has the same shape and arrangement on the upper and lower surfaces of the insertion portion 511, so it can be inserted into the gap s2 in the same way even if it is turned upside down.

[0022] (Comparison of conventional shoji screens and the shoji screens of this embodiment) In the casement window 1 with the configuration described above, the sliding door 3 is prone to deformation into a roughly parallelogram shape when viewed from the front, due to the weight of the panel 31 and the movement of the panel 31 when opening and closing, which causes the door edge vertical frame (door edge frame) 3b to sag downwards (door sag) (see Figure 6). Therefore, in the conventional casement window 1 with a shoji screen 3, the position of the setting block 4 was arranged as follows. Below the shoji screen 3, the setting block 4 was positioned near the lower horizontal frame (bottom frame) 3d of the hinge-side vertical frame (door-end frame) 3a, which is close to the support axis 30a, and near the hinge-side vertical frame (door-end frame) 3a of the lower horizontal frame (bottom frame) 3d. Furthermore, above the shoji screen 3, the setting block 4 was positioned near the upper horizontal frame (upper frame) 3c of the door edge vertical frame (door edge frame) 3b, spaced apart from the support axis 30a. Furthermore, the setting block 4 has a spacer (not shown) placed near the door edge vertical frame (door edge frame) 3b of the upper horizontal frame (upper frame) 3c, which is spaced apart from the support axis 30a. The setting block 4 and the spacer support the panel 31, in an attempt to prevent the sliding of the shoji screen 3. In other words, the lower setting block 4 supports the panel 31 near the corner of the panel 31 on the hinge side, where a load is acting downwards, while the upper setting block 4 and spacer support the panel 31 near the corner of the panel 31 on the door-side, spaced apart from the pivot axis 30a of the hinge vertical frame (door-end frame) 3a. By immobilizing the panel 31 within the frame body 30, the sliding door 3 can be prevented from sagging. However, conventionally, a spacer with the same height as the gap s1 was installed, which meant that when inserting the panel 31 into the frame 30, the panel 31 would come into contact with the interior side of the spacer, making insertion difficult and thus making the installation of the panel 31 difficult.

[0023] In the sliding door 3 of the casement window 1 of this embodiment, as described above, the spacer 5 consists of two components: a base block 50 and an insertion block 51. By inserting the panel 31 into the frame 30 and then inserting the insertion block 51 into the gap s2 from the clearance s (see Figure 7) to support the panel 31, the installation of the panel 31 is made easier, and the panel 31 can be supported in an immovable state by the setting block 4 and the spacer 5, thereby preventing the sliding door 3 from sagging.

[0024] (Modified versions of the spacer (not shown)) Modified versions of the spacer 5 include an insertion block 51 without a wedge portion 510, an insertion block 51 having a wedge portion 510 with either the upper or lower surface inclined, an insertion block 51 with a planar contact portion 5110 of the insertion portion 511, and an insertion block 51 having a protruding contact portion 5110 on either the upper or lower side of the insertion portion 511.

[0025] (Installation procedure for casement windows) Next, we will explain an example of the installation procedure for casement window 1. (Step 1) Install the casement window 1, which has been pre-assembled in the factory, into the structural opening a1 of the structural frame a. The casement window 1 incorporates a frame 2 and a shoji screen 3, and a trim strip 3e is attached to the interior facing surface 301 of the outer side of the frame body 30 of the shoji screen 3, specifically the outer side of the hinge vertical frame (end frame) 3a, the outer side vertical frame (end frame) 3b, and the upper horizontal frame (upper frame) 3c.

[0026] A pre-installed bead 30f is attached to the exterior facing surface 302 of the hinge-end vertical frame (door-end frame) 3a, door-end vertical frame (door-end frame) 3b, upper horizontal frame (upper frame) 3c, and lower horizontal frame (lower frame) 3d. Additionally, a base block 50 is attached to the upper horizontal frame (upper frame) 3c, and setting blocks 4 are attached to the lower horizontal frame (lower frame) 3d, the hinge vertical frame (door end frame) 3a, and the door edge vertical frame (door edge frame) 3b.

[0027] (Step 2) The worker removes the trim 3e and places the panel 31 on the setting block 4 attached to the lower horizontal frame (bottom frame) 3d of the frame body 30. With the panel 31 in place, the worker moves it to the outside and fits it between the setting block 4 attached to the hinge vertical frame (end frame) 3a and the door edge vertical frame (front frame) 3b. When the panel 31 is fitted into the frame 30, a clearance s (see Figure 7) is secured between the lower end of the interior-facing surface 301 of the upper horizontal frame (upper frame) 3c and the outer peripheral surface 311 of the upper end of the panel 31, and a gap s2 is secured between the inner peripheral surface 501 of the base block 50 and the outer peripheral surface 311 of the upper end of the panel 31.

[0028] (Step 3) As shown in Figure 7, the insertion block 51 is inserted into the gap s2 from the clearance s, the wedge portion 510 is pushed outwards toward the gap s2, and the insertion portion 511 is overlapped vertically with respect to the base block 50, thereby forming and positioning the spacer 5 within the gap s1.

[0029] In other words, the spacer 5 can be formed within the gap s1 by inserting the insertion block 51 into the gap s2 secured between the inner circumferential surface 501 of the base block 50 and the outer circumferential surface 311 of the upper end of the panel 31, and can also be easily placed in the gap s1. When the insertion portion 511 is in a state where it overlaps with the base block 50 within the gap s2, the upper and lower contact portions 5110 are in contact with the inner circumferential surface 501 of the base block 50 and the outer circumferential surface 311 of the upper end of the panel 31, respectively. Therefore, the spacer 5 is positioned without any gap between the inner circumferential surface 321 of the upper horizontal frame (upper frame) 3c and the upper outer circumferential surface 311 of the panel 31 within the gap s1. As a result, the panel 31 fitted into the frame 30 is supported in an immovable state within the frame 30 by the setting block 4 and spacer 5, preventing movement of the panel 31 due to its own weight or the opening and closing of the sliding door 3, and also preventing the panel 31 from rattling.

[0030] (Step 4) After positioning the spacer 5, attach the trim 3e to the interior surface 301 of the upper horizontal frame (upper frame) 3c, the interior surface 301 of the hinge vertical frame (end frame) 3a, and the interior surface 301 of the door edge vertical frame (door edge frame) 3b (see Figures 2 to 4). After the trim molding 3e is installed, the retrofit bead 31f is attached to the trim molding 3e and the interior-facing surface 303 of the lower horizontal frame (lower frame) 3d, so that the retrofit bead 31f comes into contact with both sides of the panel 31, allowing the panel 31 to be held in place from both the interior and exterior sides.

[0031] The casement window 1 of this embodiment can be installed by steps 1 to 4. In this way, the opening window 1 eliminates any gaps between the outer perimeter of the panel 31 and the setting block 4 and spacer 5, particularly in the sash 3. As a result, the panel 31, the setting block 4, and the spacer 5 become integrated, and the panel 31 can be immobilized within the frame 30. Therefore, it is possible to prevent the panel 31 from moving or rattling due to its own weight or when the sash 3 is opened and closed, and to prevent the sash 3 from sagging due to these factors.

[0032] Furthermore, in the spacer 5 placement process in step 4, the spacer 5 can be placed in the gap s1 by inserting the insertion block 51 into the gap s2. Therefore, even with a narrow clearance s, the spacer 5 can be easily placed in the gap s1.

[0033] Therefore, the casement window 1 of this embodiment prevents the sliding of the sash 3 and facilitates the installation of the panel onto the frame 30.

[0034] (The relationship between the placement of setting blocks and spacers for shoji screens in various types of casement windows) Next, we will explain the arrangement relationship between the setting block 4 and the spacer 5 relative to the shoji screen 3 in various types of casement windows 1. Note that in this explanation, only shoji screen 3 is illustrated. As shown in Figures 8 and 9, shoji screens 3 come in various forms, including vertical sliding windows, outward-opening windows (single-pane) (double-pane), inward-opening windows, vertical-axis rotating windows (eccentric axis), framed doors (single-pane) (double-pane), framed doors with a middle frame (single-pane) (double-pane), ventilation doors, etc. In all configurations of the shoji screen 3, the lower setting block 4 is positioned closer to the rotation center of the shoji screen 3, while the upper setting block 4 and spacer 5 are positioned further away from the rotation center of the shoji screen 3. In the case of a door with a middle frame, the upper and lower panels 31 are supported by setting blocks 4 and spacers 5, respectively, with the middle frame 3j as the boundary. With the setting blocks 4 and spacers 5 arranged in this manner, the panels 31 of the shoji screen 3 in various forms can be supported in an immovable state, and the shoji screen 3 can be prevented from sagging due to the weight of the panels 31 or movement. Furthermore, the panel can be easily attached to the frame 30.

[0035] While embodiments of the present invention have been described in detail with reference to the drawings and various modifiable forms have been explained, the specific configuration is not limited to these embodiments, and design changes and the like that do not depart from the spirit of the present invention are also included.

[0036] Furthermore, the aforementioned embodiments and various forms can be combined by utilizing each other's technologies, as long as there are no particular contradictions or problems in their purpose, structure, etc. [Explanation of Symbols]
