[Technical field to which the invention belongs]

 The present invention relates to a window sash, and more particularly to a window sash of a type using double glazing having a high soundproofing and heat insulating effect.

[0002]

[Prior art]

 Window sashes, such as aluminum sashes, have become indispensable components for modern residential building materials, and various measures have been taken to improve sound insulation and heat insulation. The most effective way to improve sound insulation and heat insulation is to use double glazing. If two pieces of glass are arranged at a predetermined interval in the frame, the gap between the two pieces of glass functions as an intermediate layer that separates the outside and the room, and the soundproofing effect and the heat insulating effect can be expected. become. Window sashes of this type using double glazing are used in houses that require special noise control, or in cold regions.

[0003]

[Problems to be solved by the invention]

 As described above, the window sash of the type using double glazing has improved soundproofing and heat insulating properties due to the buffering effect of the intermediate layer sandwiched between the two glasses. Therefore, it is preferable that the thickness of the intermediate layer be as large as possible. However, with the general structure of a conventional window sash, it is necessary to increase the distance between the two glasses in order to increase the thickness of the intermediate layer, and it is necessary to increase the thickness of the entire sash. However, space efficiency is reduced.

[0004] Therefore, an object of the present invention is to provide a novel structure of a window sash capable of improving soundproofing and heat insulating properties without increasing the overall thickness.

[Embodiment of the invention]

 Hereinafter, the present invention will be described based on the illustrated embodiments. FIG. 1 is a plan view showing a conventional general structure of a window sash of the type using double glazing. FIG. 1 (a) shows a state in which the sash is closed, and FIG. The open state, FIG. 1 (c), shows the sash fully opened. The window sash includes a first sliding door 10 arranged on the left side and a second sliding door 20 arranged on the right side, and is mounted in the window frame 30. A first outer glass 11 and a first inner glass 12 are fitted in the first sliding door 10 so as to be parallel to each other at a predetermined interval, and the second sliding door 20 has a second outer glass 11. The glass 21 and the second inner glass 22 are fitted so as to be parallel to each other at a predetermined interval. As described above, each of the sliding doors 10 and 20 is fitted with two pieces of glass. When the sliding doors 10 and 20 are closed as shown in FIG. 1 (a), they are sandwiched between the two pieces of glass. The void portion functions as an intermediate layer that separates the outside from the room, thereby improving the soundproofing effect and the heat insulating effect.

As described above, when the double glass is used, the soundproofing property and the heat insulating property can be improved by the cushioning effect of the intermediate layer sandwiched between the two glass sheets. The greater the thickness, the greater the increase. However, in the general structure of the conventional window sash as shown in FIG. 1, in order to increase the thickness of the intermediate layer, it is necessary to increase the distance between the two glasses, and the thickness of the entire sash is increased. As already mentioned, there is a problem that space efficiency must be reduced.

FIG. 2 is a plan view showing the basic structure of the window sash according to the present invention. FIG. 2A shows a state in which the sash is closed, and FIG. 2B shows a state in which the sash is partially opened. FIG. 2 (c) shows the sash fully opened. This window sash is also constituted by a first sliding door 100 arranged on the left side and a second sliding door 200 arranged on the right side, and is mounted in the window frame 300. Both the conventional window sash shown in FIG. 1 and the window sash of the present invention shown in FIG. 2 are common in that double glazing is fitted into each sliding door, but there is a fundamental difference in the structure. is there. That is, in the conventional window sash, as shown in FIG. 1A, two outer glass sheets are fitted into one sliding door (in this example, the first sliding door 10), and the inner glass sheet is fitted into the inner sliding door. While two sheets are fitted in the other sliding door (in this example, the second sliding door 20), in the window sash of the present invention, as shown in FIG. The third glass is fitted into one sliding door (in this example, the first sliding door 100), and the second and fourth glass from the outside are fitted into the other sliding door (in this example, the second sliding door 200). It is fitted. Thus, the structure in which the four glasses are alternated is an important feature of the present invention.

That is, the window sash according to the embodiment shown in FIG. 2A is constituted by a first sliding door 100 arranged on the left side and a second sliding door 200 arranged on the right side. Built in. Here, a first outer glass 110 and a first inner glass 120 are fitted into the first sliding door 100 so as to be parallel to each other at a predetermined interval. The second outer glass 210 and the second inner glass 220 are fitted so as to be parallel to each other at a predetermined interval. The first sliding door 100 includes a first left outer frame 111 that supports a left edge of the first outer glass 110, a first right outer frame 112 that supports a right edge of the first outer glass 110, The first inner glass 120 includes a first left inner frame 121 that supports the left edge of the first inner glass 120, and a first right inner frame 122 that supports the right edge of the first inner glass 120. Similarly, the second sliding door 200 includes a second left outer frame 212 that supports the left edge of the second outer glass 210 and a second right outer frame 211 that supports the right edge of the second outer glass 210. And a second left inner frame 222 that supports the left edge of the second inner glass 220 and a second right inner frame 221 that supports the right edge of the second inner glass 220. Actually, in addition to these frames, there is a frame that supports the upper edge and a frame that supports the lower edge of each glass, but the description is omitted here because the diagram becomes complicated. (The same applies to the conventional example of FIG. 1).

In FIG. 2A, a first left outer frame 111 and a first left inner frame 121 are connected to each other so as to be integrally movable, and a second right outer frame 211 is provided. The second right inner frame 221 is also connected to the second right inner frame 221 so as to be movable as a unit. Therefore, the first sliding door 100 functions as one sliding door in which two glasses 110 and 120 are fitted, and the second sliding door 200 is as one sliding door in which two glasses 210 and 220 are fitted. Will work. In addition, a sufficient space is provided between the first right outer frame 112 and the first right inner frame 122 to insert and remove the second left outer frame 212, and similarly, the second left outer frame A sufficient space is secured between the frame 212 and the second left inner frame 222 for inserting and removing the first right inner frame 122. Therefore, as shown in FIGS. 2 (b) and 2 (c), if the window sash is opened by pulling the second sliding door 200 leftward (or, if the first sliding door 100 is A second outer glass 210 is accommodated between the first outer glass 110 and the first inner glass 120, and the second outer glass 210 and the second inner glass 220 And the first inner glass 120 is housed between them.

As described above, the window sash according to the present invention can be opened and closed by moving the first sliding door 100 or the second sliding door 200 left and right, similarly to the conventional window sash. Moreover, the thickness of the entire sash is not different from the conventional sash. However, the thickness of the intermediate layer sandwiched between the two glasses when closed is much larger than that of a conventional sash. That is, the interval between the two glasses 110 and 120 and the interval between the two glasses 210 and 220 in the structure shown in FIG. 2A are different from those of the two glasses 11 and 12 in the structure shown in FIG. And the distance between the two glasses 21 and 22 are considerably larger. As described above, as the thickness of the intermediate layer that achieves the buffering effect increases, the soundproofing and heat insulating properties can be improved accordingly.

In the example shown in FIG. 2, the first and third glasses from the outside are fitted in the first sliding door 100, and the second and fourth glasses from the outside are fitted in the second sliding door 200. However, conversely, a structure in which the second and fourth glasses from the outside are fitted to the first sliding door 100 and the first and third glasses from the outside are fitted to the second sliding door 200 may be adopted. I don't care. When the reverse structure is adopted in this manner, a sufficient space is secured between the first right outer frame 112 and the first right inner frame 122 for inserting and removing the second left inner frame 222. Then, the second inner glass 220 is accommodated, and the first right outer frame 112 is put in and out between the second left outer frame 212 and the second left inner frame 222. In this case, a sufficient space is secured, and the first outer glass 110 is accommodated.

FIG. 3A is a plan view showing only the first sliding door 100 shown in FIG. As described above, the first outer glass 110 is fitted between the first left outer frame 111 and the first right outer frame 112, and the first left inner frame 121 and the first right inner frame 122 are inserted. The first inner glass 120 is fitted between the first inner glass 120 and the second inner glass 120. The first left outer frame 111 and the first left inner frame 121 are connected to each other so as to be integrally movable. In addition, as described above, frames are actually arranged on the upper and lower edges of the first outer glass 110 and the first inner glass 120, respectively. For this reason, taking in and out of the intermediate layer sandwiched between the two glasses 110 and 120 can be performed only through the opening slit S formed on the right side of the drawing. Of course, considering only the opening and closing function of the window sash, it is sufficient that the second left outer frame 212 and the second outer glass 210 can be put in and out through the opening slit S. However, practically, it is necessary to consider the cleaning operation of the inner side surfaces (surfaces on the intermediate layer side) of the first outer glass 110 and the first inner glass 120. It is difficult to perform such a glass surface cleaning operation only through the opening slit S.

Therefore, in practical use, it is preferable that the first left outer frame 111 and the first left inner frame 121 be fixed by metal fittings that can be connected / separated. FIG. 3B is a plan view showing an example in which the first left outer frame 111 and the first left inner frame 121 can be connected and separated by the bracket 130. In order to perform the function as a normal window sash, the first left outer frame 111 and the first left inner frame 121 are connected by the metal fitting 130, and the first sliding door 100 as a whole has one sheet. It can be moved as a board. When the surface of the glass is to be cleaned, the metal fitting 130 is removed so that the first left outer frame 111 and the first left inner frame 121 can be separated from each other. As described above, the frame supporting the first outer glass 110 and the frame supporting the first inner glass 120 can be moved separately, so that the inner surfaces of the glasses 110 and 120 can be easily moved. Be able to clean. Of course, the same applies to the other second sliding door 200, and the second right outer frame 211 and the second right inner frame 221 may be fixed by a connectable / separable metal fitting.

Next, a more practical structure of each part of the window sash according to the present invention will be described. FIG. 4 is a horizontal sectional view showing a more practical structure of the left end portion of the window sash shown in FIG. The left edge of the first outer glass 110 is accommodated in the support groove of the first left outer frame 111 and is fixed by the caulking agent C, and the left edge of the first inner glass 120 is the first left glass. It is housed in the support groove of the inner frame 121 and is fixed by the caulking agent C. FIG. 5 is a horizontal sectional view showing a more practical structure near the center of the window sash shown in FIG. The right edge of the first outer glass 110 is accommodated in the support groove of the first right outer frame 112 and is fixed by the caulking agent C. The left edge of the second outer glass 210 is the second left glass. It is housed in the support groove of the outer frame 212 and is fixed by the caulking agent C. The right end of the first inner glass 120 is accommodated in the support groove of the first right inner frame 122 and is fixed by the caulking agent C, and the left end of the second inner glass 220 is , Is accommodated in the support groove of the second left inner frame 222 and is fixed by the caulking agent C. The key fitting K1 disposed on the left side of the second left inner frame 222 is rotatably mounted on the axis A, and the key fitting K2 mounted on the left side of the first right inner frame 122. The function of locking the window sash is achieved by engaging with.

FIG. 6 is a horizontal sectional view showing the state of the left end portion when the window sash having the structure shown in FIG. 5 is completely opened (in this figure, the state before the key fitting K1 is attached is shown). It is shown). The second left outer frame 212 and the second left inner frame 222 are in contact with the first left outer frame 111 and the first left inner frame 121, respectively. Reference numerals 120 and 220 are alternately overlapped.

A point to be noted in the structure shown in FIG. 5 is that the first right outer frame 112, the second left outer frame 212, the first right inner frame 122, and the second left inner frame 222 Is that a fitting structure is formed on each of the contact surfaces. For example, when looking at the contact portion between the first right outer frame 112 and the second left outer frame 212, a fin-shaped protrusion extends from both sides and is fitted. If such a fitting structure is formed, these contact surfaces are in a fitted state in a state where the window sash is closed, and the hermeticity with respect to the intermediate layer is further improved. After all, by forming such a fitting structure, sound insulation and heat insulation can be further improved.

FIG. 7 is a side view of a specific embodiment of the window sash according to the present invention. In this example, four frames 410, 420, 430, 440 are fitted between the floor frame 310 and the top frame 320 (both of which are shown in cross section). Here, each frame corresponds to a frame supporting the glass 110, 210, 120, 220 in the example shown in FIG. 2, respectively. On the upper surface of the floor frame 310, four rails 311, 312, 313, 314 are formed, and the wheels W1, W2, W3, W4 attached to the respective frame bodies 410, 420, 430, 440 are arranged. Slide on these rails. On the other hand, support plates 321, 322, 323 are formed on the lower surface of the top frame 320, and support the upper portions of the frame bodies 410, 420, 430, 440. In this way, if the wheels are provided on the bottom of the frame supporting each glass, rails are laid along the movement path of each frame, and the wheels can roll on these rails to open and close. This allows smoother opening and closing operations.
