Modes for Carrying Out the Invention

[0007] (Example) The following will be described with reference to the drawings. The following drawings are created for the purpose of explanation, and for the sake of clarity, there may be cases where members unnecessary for the explanation are not intentionally illustrated. Also, there may be cases where members are intentionally illustrated larger or smaller for the purpose of explanation, and the drawings do not show the exact scale. In the following explanation, the same reference numerals in different figures indicate parts with the same function, and duplicate explanations in each figure are omitted as appropriate.

[0008] The building having the fitting 1 can be any building. In the embodiment, the fitting 1 as a sliding window to be installed in the opening of a concrete building will be described.

[0009] (Structure of the entire fitting) Fig. 1(o) is an internal view (appearance view) of the fitting 1 as a sliding window seen from inside the concrete building. In the present embodiment, in the fitting 1, a total of 10 sets of the fixing members 12 of the present invention, each set consisting of a frame-side fixing member 3 and a housing-side fixing member 2, are provided in three sets each on the upper and lower frames and two sets each on the left and right vertical frames with respect to the aluminum frame 11 provided in the opening of the concrete building. Also, two self-weight receiving bolts 5 as a structure for receiving the self-weight of the fitting 1 are provided. Note that the number of the fixing members 12 can be appropriately set according to the size of the fitting 1. Also, it is not necessary to provide the fixing members 12 of the present invention for all the frames 11. For example, construction such as using the fixing members 12 of the present invention only for the upper frame and providing other known fixing means for the lower frame can also be carried out.

[0010] Fig. 1(a) is a cross-sectional view taken between A - A' of Fig. 1(o), and for each of the upper and lower frames, a housing-side fixing member 2 and a frame-side fixing member 3 are provided. In the present embodiment, the housing-side fixing member 2 is a male locking member and the frame-side fixing member 3 is a female locking member, but this relationship may be reversed, and it is also possible to make the housing-side fixing member 2 a female locking member and the frame-side fixing member 3 a male locking member.

[0011] Figure 1(b) is a cross-sectional view taken along line B-B' of Figure 1(o), and a self-weight receiving bolt 5 for receiving the self-weight of the frame 11 is provided in the lower frame portion. Figure 1(c) is a cross-sectional view taken along line C-C' of Figure 1(o), and a body-side fixing member 2 and a frame-side fixing member 3 are provided for each of the left and right vertical frames. In the present embodiment, the body-side fixing member 2 is a male locking member, and the frame-side fixing member 3 is a female locking member. However, this relationship may be reversed, and it is also possible to make the body-side fixing member 2 a female locking member and the frame-side fixing member 3 a male locking member.

[0012] (Structure of fixing members for upper and lower frames) Figure 2 is an enlarged view of Figure 1(a) and corresponds to a longitudinal sectional view of the fitting 1 for the upper and lower frames to which the fixing member 12 of the present invention is applied. On the other hand, Figure 3 is an enlarged view of a part of the perspective view of the fitting 1. Figure 3(a) is a front view of the upper frame portion, and Figure 3(b) is a front view of the lower frame portion. The body-side fixing member 2, which is a fixing member 12 provided on the inner peripheral side of the body, is configured as a male locking member in the present embodiment. The body-side fixing member 2 as a male locking member is an integrally molded product in which a protrusion 22 extends from the main body portion 21. The body-side fixing member 2 is fixed to the body by screwing in the concrete nail 4 from the obliquely downward direction in the front of the building interior at a position corresponding to the frame-side fixing member 3 at a position corresponding to a predetermined entrance / exit position of the window. As can be understood from Figures 2 and 3, the main body portion 21 has a rectangular shape in which the length in the finding direction is slightly longer than the length in the prospecting direction, while the protrusion 22 has a strip-like form in which the dimension in the finding direction is overwhelmingly longer than the prospecting dimension.

[0013] The frame-side fixing member 3, which is a fixing member 12 provided on the outer peripheral side of the frame 11, is configured as a female locking member in the present embodiment. The frame-side fixing member 3 is attached to the outer peripheral end of the frame by an appropriate means such as a screw 32 at a position corresponding to the body-side fixing member 2. The frame-side fixing member 3 as a female locking member has a groove 31 that engulfs the protrusion 22 of the body-side fixing member 2 over the longitudinal direction of the frame.

[0014] As shown in FIG. 2, the depth of the groove 31 has a depth allowance that can be adjusted according to the appropriate vertical installation position at the opening of the fitting 1, and the fitting dimension of the protrusion 22 is absorbed by the existence of this groove depth. On the other hand, the cross-sectional shape of the tip of the protrusion 22 is a substantially elliptical shape like a crushed circle, which is for appropriately coping with the unevenness that inevitably occurs on the inner peripheral surface of the housing opening. With this shape, even when the housing-side fixing member 2 is fixed at an angle slightly deviated from the horizontal, the contact of the tip of the protrusion 22 with the groove 31 is made appropriate.

[0015] (Structure of lower frame self-weight receiving part) FIG. 4 is an enlarged view of only the lower frame portion of FIG. 1(b), showing the periphery of the self-weight receiving bolt 5 as a structure for receiving the self-weight of the fitting 1. In the present embodiment, the number of the self-weight receiving bolts 5 is two, but this number is set appropriately according to the weight of the fitting 1. The self-weight receiving bolt 5 is installed on the housing in a state where it is rotationally adjusted so that the height position with respect to the opening of the entire fitting 1 is appropriate. In the case of welding while adjusting the installation height as in the prior art, work by a skilled worker is required and it is also accompanied by danger. However, in the embodiment of the present invention, the height adjustment only requires rotating the self-weight receiving bolt 5, so the work is extremely easy. Nevertheless, the height positioning of the fitting 1 can be made highly accurate.

[0016] (Structure of fixing member for left and right vertical frames) FIG. 5 is an enlarged view of only the right vertical frame portion of FIG. 1(c), corresponding to a part of the cross-sectional view of the fitting 1 for the right vertical frame to which the fixing member 12 of the present invention is applied. On the other hand, FIG. 6 is an enlarged view of a part of the perspective view of the fitting 1, which is a front view of the right vertical frame portion. The body-side fixing member 2, which is a fixing member 12 provided on the inner peripheral side of the body, is configured as a male locking member in this embodiment. The body-side fixing member 2 as a male locking member is an integrally formed object with a ridge 22 extending from the main body portion 21. The body-side fixing member 2 is fixed to the body by screwing a concrete nail 4 from the obliquely left direction in the front of the building interior at a position corresponding to the frame-side fixing member 3 at a position corresponding to a predetermined entry / exit position of the window. As can be understood from FIGS. 5 and 6, the main body portion 21 has a rectangular shape with a length in the frame longitudinal direction slightly longer than the length in the prospective direction, while the ridge 22 has a bar-like form with a finding dimension overwhelmingly longer than the prospective dimension.

[0017] The frame-side fixing member 3, which is a fixing member 12 provided on the outer peripheral side of the frame 11, is configured as a female locking member in this embodiment. The frame-side fixing member 3 is attached to the outer peripheral end of the frame by an appropriate means such as a screw 32 at a position corresponding to the body-side fixing member 2. The frame-side fixing member 3 as a female locking member has a groove 31 that engages the ridge 22 of the body-side fixing member 2 extending in the frame longitudinal direction.

[0018] As shown in FIG. 5, the depth of the groove 31 has a receiving depth margin that can be adjusted according to the appropriate left-right installation position at the opening of the fitting 1, and the fitting dimension of the ridge 22 is absorbed by the existence of this groove depth. On the other hand, the cross-sectional shape of the tip of the ridge 22 is a substantially elliptical shape like a crushed circle, which is for appropriately coping with the unevenness that inevitably occurs on the inner peripheral surface of the body opening. With this shape, even if the body-side fixing member 2 is fixed at an angle slightly deviated from the vertical, the contact of the tip of the ridge 22 with the groove 31 is made appropriate.

[0019] (Construction procedure of the fitting) The construction procedure of the fitting 1 of the present invention will be described. First, install the window frame at a predetermined position (height, level, entry / exit) together with the frame-side fixing member 3 pre-embedded around the window frame. After installing the window frame, turn the self-weight bearing bolt 5 provided in advance on the lower side of the lower frame to determine the rotational position that gives an appropriate height position, and then ground the entire window frame to the building body so as to entrust the self-weight of the window frame to the building body. Slide and move the body-side fixing member 2 so that the tip of the protrusion 22 fits into the opening side of the groove 31 of the frame-side fixing member 3 from the position where the frame-side fixing member 3 is replaced. After arranging the body-side fixing member 2 at a predetermined entry / exit position of the window, obliquely drive the concrete bolt 4 into the body-side fixing member 2 to fix the body-side fixing member 2 to the opening building body. Since the concrete bolt 4 can be driven from the inside of the living room, it is convenient. The state at this point is the perspective view of Fig. 1(o). Finally, store the outer shutter and the inner shutter (not shown) in the window frame, fill the gap between the building body opening and the frame 11 with an appropriate filler such as a heat insulating material, and then cover it with a decorative board to complete the fitting 1.

[0020] In this way, the installation process of the frame 11 in the fitting 1 of the present invention does not require welding work on site, so it does not involve work-related risks and does not require skill either. The construction period can be shortened and the construction can be facilitated, and it can be evaluated as construction saving. All of this is derived from the structural features of the fitting 1 of the present invention. In the current construction site situation where labor saving and efficiency improvement of various operations are required, especially in the scenario where various infectious diseases such as COVID-19 are spreading, the contribution of the present invention is great. Furthermore, in this embodiment, almost all operations can be performed from inside the building, so it is also suitable for work at high floors.

[0021] Note that, as shown in FIG. 7, it is also possible to install the window frame by fitting the protrusion 22 into the groove 31 of the frame-side fixing member 3 in advance. When constructing in this way, after installing the window frame, pull out the protrusion 22 from the groove 31, confirm that the body-side fixing member 2 is arranged at the predetermined entry / exit position of the window, and fix the body-side fixing member 2 to the body with the concrete nail 4. Since the groove 31 and the protrusion 22 have a finding dimension of a certain length, the body-side fixing member 2 will not easily fall off from the groove 31 of the upper frame, but for the lower frame and the left and right vertical frames, it will easily fall off. Therefore, it is advisable to temporarily fix the body-side fixing member 2 with a curing tape T or the like. By doing so, further labor and efficiency savings of the work can be achieved.

[0022] (Alternative Embodiment) In the first embodiment of the present invention, the main body portion 21 was fixed to the body by screwing the concrete nail 4 from the front inside the building at a position corresponding to the frame-side fixing member 3 at a position corresponding to the predetermined entry / exit position of the window, but the fixing mode is not limited to this. Depending on the working environment, if work from the outside of the building is acceptable, as shown in FIG. 8, it is also possible to fix the body-side fixing member 2 to the body by screwing the concrete nail 4 from the front outside the building. The concrete holding of the body opening often has more margin on the outer surface side. As can be easily understood by comparing FIG. 2 and FIG. 8, by screwing the concrete nail 4 from the outside of the building, interference with the frame-side fixing member can be avoided with a margin, so there is an advantage that the work becomes easier compared to the case of screwing the concrete nail 4 from inside the building.

[0023] FIG. 9 is a view showing the state of the upper frame portion for yet another embodiment. In the first embodiment of the present invention, the body-side fixing member 2 is a male locking member and the frame-side fixing member 3 is a female locking member. However, in the modified example shown in FIG. 9, this relationship is reversed. That is, the body-side fixing member 2 is a female locking member and the frame-side fixing member 3 is a male locking member. Of course, it is also possible to apply this modified example to the mode of screwing the concrete bolt 4 from the front of the building exterior shown in FIG. 8.

[0024] FIG. 10 is a view showing the state of the upper frame portion for yet another embodiment. As shown in the cross-sectional view of (a), the body-side fixing member 2 is divided into two members, upper and lower, and these are fixed by rivets 23. The screwing of the concrete bolt into the body is performed from inside the room. Since it is screwed in straight instead of obliquely, the work becomes even easier. Also, as can be understood from the conceptual perspective view of (b), it is possible to flexibly cope with a situation where the fitting 1 has to be installed non-parallel to the body due to unevenness that inevitably occurs.

[0025] FIG. 11 is a modified example of the embodiment shown in FIG. 2. In the embodiment shown in FIG. 2, since the height position is adjusted to an appropriate height by the self-weight bearing bolt 5, there is no particular means for fixing both after the tip of the protrusion 22 is engaged with the groove 31. However, FIG. 11 is provided with a screw 33 as a means for fixing the protrusion 22 and the groove 31. The following will be described with reference to the drawings. As shown in Fig. 11, the depth of the groove 31 has a depth allowance that can be adjusted according to the appropriate vertical installation position at the opening of the fitting 1, and the fitting dimension of the protrusion 22 is absorbed by the existence of this groove depth. On the other hand, the cross-sectional shape of the tip of the protrusion 22 is a substantially elliptical shape like a crushed circle, which is for appropriately coping with the unevenness that inevitably occurs on the inner peripheral surface of the housing opening. Due to this shape, even when the main body 21 is fixed at an angle slightly deviated from the horizontal, the contact of the tip of the protrusion 22 with the groove 31 of the fitting 1 is made appropriate. Due to the characteristics of such a shape, after adjusting the appropriate positions for the vertical position and elevation angle, the protrusion 22 and the groove 31 are fixed by the screw 33 so as not to be displaced.

[0026] (Construction procedure of the embodiment in Fig. 11) First, install the window frame at a predetermined position (height, orientation, entry / exit) together with the frame-side fixing member 3 pre-embedded around the window frame. After installing the window frame, turn the self-weight receiving bolt 5 provided in advance on the lower side of the lower frame to determine the rotational position for giving an appropriate height position, and then ground the entire window frame to the housing so that the self-weight of the window frame is entrusted to the housing. Slide and move the body-side fixing member 2 so that the tip of the protrusion 22 fits in from the opening side of the groove 31 of the frame-side fixing member 3 from the position where the frame-side fixing member 3 is removed. After arranging the body-side fixing member 2 at the predetermined entry / exit position of the window, twist the concrete nail 4 obliquely into the body-side fixing member 2 to fix the body-side fixing member 2 to the opening housing. Since the twisting of the concrete nail 4 can be performed from the inside of the living room, it is convenient. After that, confirm that the protrusion 22 is properly recessed in the groove 31, and fix both of them with the screw 33 so that the protrusion 22 and the groove 31 do not shift. Finally, store the outer and inner shutters (not shown) in the window frame, fill the gap between the housing opening and the frame 11 with an appropriate filler such as a heat insulating material, and then cover it with a decorative board to complete the fitting 1.

[0027] Figure 12 shows a modification of the embodiment shown in Figure 8. In the embodiment shown in Figure 8, since the height position is adjusted to the appropriate height by the self-weight bearing bolt 5, there is no particular means for fixing the two after the tip of the protrusion 22 is engaged with the groove 31. However, Figure 12 is provided with a screw 33 as a means for fixing the protrusion 22 and the groove 31. Since the structure and construction procedure are the same as those of the embodiment in Figure 11, the description will be omitted.

[0028] As described above, the fitting 1 according to the embodiment of the present invention has been described in detail with reference to the drawings, and its structure and construction procedure have been explained. However, the specific configuration is not limited to these embodiments, and design changes and the like within the scope not departing from the gist of the present invention are also included in the present invention. For example, the fitting 1 may be a single large panel window instead of a sliding window. Needless to say, the present invention can also be applied to an opening where the fitting 1 can be installed, not only to an opening of a concrete building but also to an opening of a wooden building. Regarding the relationship between the building body side fixing member 2 and the frame side fixing member 3 described above, it can be arbitrarily changed which of them bears the male locking member and the female locking member. Even in a modification where the building body side fixing member 2 is the male locking member and the frame side fixing member 3 is the female locking member for the upper and lower frames, and the building body side fixing member 2 is the female locking member and the frame side fixing member 3 is the male locking member for the left and right vertical frames, it is included in the scope of the present invention.

[0029] Also, as long as there are no particular contradictions or problems in the purpose and configuration of the above-described embodiments, it is possible to combine them by diverting each other's technologies.
