Description

The present invention relates to fittings that are installed in openings in buildings.

Conventionally, when fitting a fixture to an opening in a building, insert bars and forms are formed to match the finished shape of the structure and fixture frame that will form the opening, concrete is poured, and then the insert bars embedded in the structure to attach the fixture frame are welded to connecting members such as sash anchors to secure the fixture to the opening.

However, this type of construction method, which is based on the conventional connection structure of fittings, requires work involving other trades such as welding and plastering in addition to the fitting work, and construction work tends to be lengthy.
The present invention aims to provide a fitting having a structure that allows a fitting frame material to be attached to an opening in a building using a simple construction method without relying on conventional construction methods.

The present invention has solved the above-mentioned problem by providing a fixture comprising a frame and a fixing member, the fixing member being attached to at least one of the upper and lower frames or left and right vertical frames of the frame, a frame-side fixing member attached to the inner periphery of the frame, and a frame-side fixing member attached to the outer periphery of the frame, one of the frame-side fixing member and the frame-side fixing member being a male locking member and the other being a female locking member, the male locking member having a main body and a protrusion which has a bulge at its tip and is formed separately from the main body , the protrusion being formed so as to be fitted into the main body from the longitudinal direction of the frame, the female locking member having a groove extending along the longitudinal direction of the frame, the protrusion being fitted into the groove from the opening side of the frame in the longitudinal direction, with the bulge abutting the groove .

It is possible to provide fittings with a structure that allows fitting frames to be attached to openings in buildings using simple construction methods.

(Example)
The following description will be given using drawings, but the drawings are created for explanatory purposes, and in order to make the description easier to understand, some components not necessary for the description may not be shown intentionally. In addition, some components may be shown intentionally large or small for the purpose of explanation, and the drawings are not drawn to an accurate scale. In the following description, the same reference numerals in different drawings indicate parts with the same function, and duplicate descriptions in each drawing will be omitted as appropriate.

Any building may be used as long as it has the fitting 1. In the embodiment, the fitting 1 is described as a sliding window that is fitted into an opening in a concrete building.

(Overall structure of the fixture)
Fig. 1(o) is an interior view (appearance view) of a fitting 1 as a sliding window seen from inside a concrete building. In this embodiment, the fitting 1 is provided with a total of ten sets of fixing members 12 of the present invention, each of which is a pair of a frame side fixing member 3 and a body side fixing member 2, for an aluminum frame 11 provided at an opening of a concrete building, with three sets on each of the upper and lower frames and two sets on each of the left and right vertical frames. In addition, two weight-bearing bolts 4 are provided as a structure for bearing the weight of the fitting 1.
The number of fixing members 12 can be set appropriately depending on the size of the fitting 1. Also, it is not necessary to provide the fixing members 12 of the present invention to all of the frames 11, and for example, it is also possible to use the fixing members 12 of the present invention only for the upper frame and provide other known fixing means for the lower frame.

Figure 1(a) is a cross-sectional view taken along line A-A' in Figure 1(o), and a body-side fixing member 2 and a frame-side fixing member 3 are provided for each of the upper and lower frames. In this embodiment, the body-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 the body-side fixing member 2 may be a female locking member, and the frame-side fixing member 3 may be a female locking member.

Figure 1(b) is a cross-sectional view taken along line B-B' in Figure 1(o), in which a weight-bearing bolt 4 that bears the 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' in Figure 1(o), in which 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 this embodiment, the body-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 the body-side fixing member 2 may be a female locking member, and the frame-side fixing member 3 may be a female locking member.

(Structure of fixing members for upper and lower frames)
Fig. 2 is an enlarged view of Fig. 1(a) and corresponds to a vertical cross-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, Fig. 3 is an enlarged view of a part of the appearance of the fitting 1, Fig. 3(a) is a front view of the upper frame portion, and Fig. 3(b) is a front view of the lower frame portion.
In this embodiment, the frame-side fixing member 2, which is the fixing member 12 provided on the inner periphery of the frame, is configured as a male locking member. The frame-side fixing member 2 as a male locking member is configured by assembling a protrusion 22 to a main body 21. The main body 21 is fixed to the frame by two concrete rivets 23 arranged in the front direction with the protrusion 22 between them, at a position according to a predetermined entry/exit position of the window and corresponding to the frame-side fixing member 3. The main body 21 is provided with a key groove and a screw hole for a screw 24 so that the protrusion 22 can be fixed after being fitted into the main body 21 from the front direction (longitudinal direction of the frame).
As can be seen from Figures 2 and 3, the main body 21 has a rectangular shape with the length in the front direction being slightly longer than the length in the front direction, whereas the protrusion 22 literally has a strip shape with the front dimension being overwhelmingly longer than the front dimension.

In this embodiment, the frame-side fixing member 3, which is the fixing member 12 provided on the outer periphery of the frame 11, is configured as a female locking member. The frame-side fixing member 3 is attached to the outer periphery of the frame at a position corresponding to the frame-side fixing member 2 by an appropriate means such as a screw 32. The frame-side fixing member 3 as a female locking member has a groove 31 that fits over the protrusion 22 of the frame-side fixing member 2 along the longitudinal direction of the frame.

As shown in Figure 2, the depth of the groove 31 has a sufficient insertion depth to allow for adjustment according to the appropriate vertical installation position in the opening of the fitting 1, and the presence of this groove depth absorbs the fitting dimensions of the protrusion 22. Meanwhile, the cross-sectional shape of the tip of the protrusion 22 is a roughly elliptical shape resembling a squashed circle, which is intended to appropriately deal with the unevenness that inevitably occurs on the inner periphery of the opening in the building structure, and this shape ensures that the tip of the protrusion 22 will properly contact the groove 31 even if the main body 21 is fixed at an angle slightly off horizontal. Due to the characteristics of this shape, the appropriate position in terms of vertical position and elevation angle is adjusted, and the protrusion 22 and groove 31 are fixed with screws 33 to prevent misalignment.

(Structure of the lower frame weight support part)
1(b) and shows the vicinity of the weight-bearing bolts 4 as a structure for bearing the weight of the fitting 1. In this embodiment, the number of weight-bearing bolts 4 is two, but this number is set appropriately depending on the weight of the fitting 1.
The weight-supporting bolt 4 is installed on the framework after being rotated and adjusted so that the height position of the entire fitting 1 relative to the opening is appropriate.
As in the past, welding while adjusting the installation height required the work to be done by a skilled craftsman and was also dangerous, but in the embodiment of the present invention, the height is adjusted by rotating the weight-receiving bolt 4, so that the work is significantly easier and the height of the fitting 1 can be positioned with high precision.

(Structure of fixing members of left and right vertical frames)
Fig. 5 is an enlarged view of only the right vertical frame portion of Fig. 1(c), and corresponds 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 appearance of the fitting 1, and is a front view of the right vertical frame portion.
In this embodiment, the frame-side fixing member 2, which is the fixing member 12 provided on the inner periphery of the frame, is configured as a male locking member. The frame-side fixing member 2 as a male locking member is configured by assembling a protrusion 22 to a main body 21. The main body 21 is fixed to the frame by two concrete rivets 23 arranged in the projection direction with the protrusion 22 between them, at a position corresponding to the predetermined entry and exit position of the window and corresponding to the frame-side fixing member 3. The main body 21 is provided with a key groove and a screw hole for a screw 24 so that the protrusion 22 can be fixed after being fitted into the main body 21 from the longitudinal direction of the frame.
As can be seen from Figures 5 and 6, the main body 21 has a rectangular shape with its length in the frame longitudinal direction being slightly longer than its length in the projection direction, whereas the protrusion 22 literally has a strip shape with its projection dimension being overwhelmingly longer than its projection dimension.

In this embodiment, the frame-side fixing member 3, which is the fixing member 12 provided on the outer periphery of the frame 11, is configured as a female locking member. The frame-side fixing member 3 is attached to the outer periphery of the frame at a position corresponding to the frame-side fixing member 2 by an appropriate means such as a screw 32. The frame-side fixing member 3 as a female locking member has a groove 31 that fits over the protrusion 22 of the frame-side fixing member 2 along the longitudinal direction of the frame.

As shown in Figure 5, the depth of the groove 31 has a sufficient insertion depth to be adjusted according to the appropriate left and right installation position in the opening of the fitting 1, and the existence of this groove depth absorbs the fitting dimensions of the protrusion 22. Meanwhile, the cross-sectional shape of the tip of the protrusion 22 is a roughly elliptical shape like a squashed circle, which is designed to appropriately deal with the unevenness that inevitably occurs on the inner surface of the opening of the building structure, and this shape ensures that the tip of the protrusion 22 will properly contact the groove 31 even if the main body 21 is fixed at an angle slightly off the vertical. Due to the characteristics of this shape, the appropriate position for the left and right position and left and right angle is adjusted, and the protrusion 22 and groove 31 are fixed with screws 33 to prevent misalignment.

(Installation procedure for fittings)
The installation procedure for the fitting 1 of the present invention will be described.
First, the frame-side fixing member 2 is attached with screws or rivets from the predetermined window entrance/exit position and the predetermined position of the frame-side fixing member 3 for mounting the window around the four inner sides of the frame opening.
Next, the window frame is installed in a specified position (height, offset, access) together with the frame side fixing members 3 that are pre-assembled around the four sides of the window frame.
After the window frame is installed, a weight-receiving bolt 4 previously provided on the lower side of the lower frame is turned to determine a rotation position that provides an appropriate height position, and then the entire window frame is grounded on the frame so that the weight of the window frame is placed on the frame.
Then, the base end of the protrusion 22 is inserted from the position past the frame side fixing member 3 so that it fits into the key groove from one small end of the main body 21 of the frame side fixing member 2, and the tip of the protrusion 22 is slid so that it fits into the opening side of the groove 31 of the frame side fixing member 3.
Thereafter, it is confirmed that the ribs 22 are properly inserted into the grooves 31, and the ribs 22 and the grooves 31 are fixed with screws 33 so that they do not shift from each other. The ribs 22 are sandwiched between the screws 24 by screwing the screws 24 into the screw holes located on both sides of the visible width of the ribs 22, so that they cannot move from the main body 21. The state at this point is shown in Fig. 1(o). In the embodiment of the present invention, the ribs 22 are fixed with the screws 33 and sandwiched between the screws 24 in combination, but it is also possible to use either one of these methods.
Finally, the outer and inner screens (not shown) are placed inside the window frame, the gap between the opening in the main structure and the frame 11 is filled with an appropriate filler such as an insulating material, and then the gap is covered with a decorative panel to complete the fitting 1.

In this way, the process of installing the frame 11 on the fitting 1 of the present invention does not require on-site welding, so there is no danger in the work, no skill is required, and the construction period is shortened and construction is simplified, making it truly a construction-saving process, all of which is derived from the structural features of the fitting 1 of the present invention. In the current situation at construction sites where various infectious diseases such as COVID-19 are spreading and there is a growing demand for labor-saving and efficient work, the contributions made by this invention are significant.

As shown in Figure 7, it is also possible to install the window frame by fitting the ridges 22 into the grooves 31 of the frame-side fixing member 3 in advance. The grooves 31 and the ridges 22 have a fixed length, so the ridges 22 will not easily fall out of the grooves 31 of the upper frame, but they will easily fall out of the lower frame and the left and right vertical frames, so it is a good idea to temporarily secure them in place with masking tape T or the like. Of course, the ridges 22 of the upper frame may also be temporarily secured in place. The method of attaching the main body 21 of the protrusion 22 when the protrusion 22 is fitted into the groove 31 is to first slide the protrusion 22 that was fitted into the groove 31 of the frame side fixing member 3 of the four-sided frame in the longitudinal direction of the frame, and from the position where it has cleared the frame side fixing member 3, insert the base end of the protrusion 22 so that it fits into the key groove from one small end of the main body 21 of the frame side fixing member 2, while sliding the tip of the protrusion 22 so that it fits into the opening side of the groove 31 of the frame side fixing member 3.
In this way, it is possible to further reduce the labor required and improve the efficiency of the work.

(Another embodiment)
In the first embodiment of the present invention, the main body 21 was fixed to the structure by two concrete rivets 23 arranged in the forward direction, sandwiching the protrusion 22, at a position corresponding to the specified entry and exit position of the window and at a position corresponding to the frame side fixing member 3, but the manner of fixing is not limited to this.
The main body 21 has a certain degree of expansion in the front and rear directions, and the contact area with the building structure is also of a certain size. As a result, if the front dimension of the main body 21 is made larger to further increase the contact area, as shown in Figure 8, it is possible to obtain sufficient support even in a configuration in which the concrete rivets 23 arranged on the inside of the building are eliminated and multiple concrete rivets 23 are arranged side by side on the outside of the building in the front direction.
Alternatively, if there is no support for the building frame, this can be actively utilized by making the main body 21 L-shaped and driving the concrete rivets 23 horizontally as shown in Figure 9. The L-shape can provide sufficient support. Also, this configuration makes it easier to work from inside the building.

Figure 10 shows the upper frame portion of 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, but the embodiment shown in Figure 10 reverses this relationship. In other words, the body-side fixing member 2 is a female locking member, and the frame-side fixing member 3 is a female locking member.

The above describes the fitting 1 according to the embodiment of the present invention in detail with reference to the drawings, and describes its structure and construction procedure. However, the specific configuration is not limited to these embodiments, and the present invention includes design changes within the scope of the present invention. For example, the fitting 1 may be a single large panel window instead of a sliding window. It goes without saying that the present invention can be applied to openings in wooden buildings, not just openings in concrete buildings, in which the fitting 1 is installed. As already mentioned, the relationship between the body side fixing member 2 and the frame side fixing member 3 can be arbitrarily changed as to which member serves as the male locking member and which as the female locking member. Although the 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, a modified example in which the 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 is also included in the scope of the present invention.

Furthermore, the above-mentioned embodiments can be combined by reusing each other's technologies, so long as there are no particular contradictions or problems in their purpose and configuration, etc.
