Description

  The present invention relates to an opening device suitably used for building openings such as houses and public facilities and a manufacturing method thereof, and more particularly, to an opening device capable of improving heat insulation performance and excellent in appearance and a manufacturing method thereof. .

  A so-called sash window provided at the opening of the building can be freely opened and closed to open and close the room, and allows people and objects to enter and exit and to ventilate. Moreover, the shoji which opens and closes has a panel which has translucency, such as a glass panel. Thereby, even in the closed posture, light can be taken into the room, and the indoor environment can be improved, such as brightening the room and warming it up.

  On the other hand, in the sash window, metal is used for many parts other than the glass panel, and therefore, the heat insulation tends to be lower than that of a normal wall or the like. Thermal insulation is one of the important performances required for buildings, and its importance is particularly high in cold regions.

  In contrast, Patent Document 1 discloses a sash with improved heat insulation. In this opening device, each of the frame and the shoji fold is divided into an indoor member and an outdoor member, which are connected by a resin material. According to this, the movement of heat inside and outside the room is blocked by the resin material, and the heat insulation of the opening device can be improved.

  Further, Patent Document 2 discloses a structure in which a protrusion is provided on the inner bottom surface of a glazing channel and is attached so as to be embedded in a sealing material filled between panels of a multilayer glass panel.

  Here, the spacers 44, 44,... Have a main function of setting a gap between the plate glass 42 and the plate glass 43 to a predetermined size, but a desiccant can also be included therein. According to this, it becomes possible to maintain the inside of this space at an appropriate humidity.

  On the other hand, the sealing materials 45, 45,... Have a main function of maintaining water tightness while bonding the plate glass 42 and the plate glass 43. Further, as described later, since the protruding portions 64 of the glazing channel 60 are inserted into the sealing materials 45, 45,..., The sealing materials 45, 45,. From this point of view, a silicon-based or polysulfide-based adhesive is preferable.

  The outer peripheral tape 48 is a strip-shaped tape material wound along the circumferential direction of the outer periphery of the multilayer glass panel 41 so as to cover the end surface of the multilayer glass panel 41 from above the sealing material 45. Thus, as will be described later, when the glazing channel 60 is attached to the fluid sealing material 45, the glazing channel 60 can be prevented from being contaminated by the sealing material 45.

  As will be described later, the outer peripheral tape 48 is provided with a slit 48a through which the protrusion 64 of the glazing channel 60 passes.

  The material of the outer peripheral tape 48 is preferably an adhesive tape having polyester, polypropylene, vinyl chloride, cellophane tape or aluminum as a base material and an adhesive on one side.

  In the present embodiment, as described above, the outer peripheral tape 48 does not necessarily have to be disposed over the entire end surface of the multilayer glass panel 41, and includes at least two corners among the four corners existing in the circumferential direction. It suffices if they are arranged. This is because the corner portion is most likely to cause contamination of the glazing channel by the sealing material. In the present embodiment, the outer peripheral tape is arranged over the entire circumference from the viewpoint of preventing the contamination more reliably.

  The glazing channel 60 is a long member formed so as to cover the end portion of the multilayer glass panel 41, and a cross section perpendicular to the longitudinal direction appears well in FIG. 5B, for example. As can be seen, the glazing channel 60 has a substantially U-shaped cross section, and includes a piece 61 and two pieces 62 and 63 erected so as to face each other from both ends of the piece 61. Accordingly, an opening is formed in the gap between the one end side of the piece 62 and the piece 63. Here, the “end portion of the glass panel” is a concept including an end surface, and further including an indoor side surface of the glass panel and an outer peripheral end portion of the indoor side surface.

  In addition, seal pieces 62a and 63a are provided on one end side of the pieces 62 and 63 so as to face each other so as to narrow the opening. Further, fin-shaped portions 62 b and 63 b are formed on the surfaces of the pieces 62 and 63 facing each other.

  Further, of the surface of the piece 61 that forms the bottom of the glazing channel 61, a protrusion that stands on the same side as the side on which the pieces 62 and 63 are erected is located approximately at the center in the width direction (up and down direction in FIG. 5). A portion 64 is arranged. The protruding portion 64 is provided with a retaining portion 64a at the tip thereof so as to swell.

  Such a protrusion 64 may be formed over the entire length of the glazing channel 60 in the longitudinal direction, but is not necessarily limited to this, and may be partly or intermittently formed. .

  Examples of the material for the glazing channel 60 include vinyl chloride and silicon materials. In addition, it is possible to combine hard and soft materials for these materials, or to use only soft materials.

  Further, the glazing channel 60 may be provided with a drain hole. As a result, water that has entered the glazing channel 60 can be discharged. The site | part which provides a hole is not specifically limited, You may provide in any one or any of the piece 61, the pieces 62, and 63. FIG.

  The above-mentioned door-toe fence 50, the outside summoning fence 51, the horizontal fences 52 and 53, the multi-layer glass panel 41, the outer peripheral tape 48 and the glazing channels 60, 60,... Have the following attachment structure. This will be described with reference to FIG. Here, the door toe fence 50 will be described as an example. Since the attachment structure with the other coffins (51, 52, 53) is substantially the same as that of the door-end coffin 50, description thereof is omitted.

  As can be seen from FIG. 5, the end surface of the multilayer glass panel 41 is covered with an outer peripheral tape 48. In addition, the end portion of the multi-layer glass panel 41 is inserted into the U-shaped inner side of the glazing channel 60 including the outer peripheral tape 48 and arranged so as to be surrounded. At this time, the protrusion 64 of the glazing channel 60 is provided so as to pass through the slit 48 a of the outer peripheral tape 48 and be included inside the sealing material 45. Thereby, the multilayer glass panel 41 and the glazing channel 60 are fixed. In addition, the retaining portion 64a provided at the tip of the protruding portion 64 makes the fixing more reliable and strong.

  On the other hand, the seal portions 62a and 63a and the fin-like portions 62b and 63b provided on the pieces 62 and 63 are in contact with the surfaces of the plate glasses 42 and 43 to ensure watertight and airtightness.

  It arrange | positions so that the edge part of the glazing channel 60 and the multilayer glass panel 41 may be included in the clearance gap between the piece 50b and the piece 50c.

  In this way, the structure in which the double-glazed glass panel 41 and the glazing channel 60 are fixed and fitted to the ridge (50, 51, 52, 53) can be formed thinner than the conventional one. It becomes possible. If the glazing channel and the double-glazed glass panel are not fixed, and the heel is thinned, the strength of the heel is low, so the heel is deformed when the shoji is forced by opening / closing or a pressure difference between the inside and outside. There may be a problem with water tightness and airtightness with the multilayer glass panel. Since the opening device of the present embodiment can solve such a problem, the ridge can be formed thinner than before, and the multilayer glass panel portion can be enlarged. That is, it is possible to provide an opening device that is excellent in daylighting performance and excellent in appearance. Moreover, since the multilayer glass panel part is excellent in heat insulation compared with a ridge, it becomes possible to improve the thermal insulation by making the ridge thin and increasing the multilayer glass panel section. Specifically, the size in the direction in which the wrinkles are found is preferably 36 mm or less. Thereby, an impression can be strongly given from the viewpoint of appearance, and the effect is remarkable in improving heat insulation.

  The description of the opening device 10 will be continued. As shown in FIG. 1 to FIG. 3, the inner shoji 70 is provided with a door toe wall 80, an in-house summoning pot 81, reeds 82 and 83, a multi-layer glass panel 71, and a glazing channel 90. As for the internal shingles 70, the other parts of the inner shingles 70 that are different in shape due to the external shingles and the inner shingles are the same as those of the inner shingles 40 described above, and thus the description thereof is omitted here.

The opening device 1 described above further includes the following features. This will be described with reference to FIGS.
The position indicated by B in FIGS. 2 and 4 is compared with the position indicated by A in the closed posture of the opening device 1. The position indicated by B is a position where the end portions in the direction of finding the door-end fences 50 and 80 are arranged in a posture in which the shojis 40 and 70 are closed. On the other hand, the position indicated by A is the position at which the inner ends of the cover members 18 and 22 in the direction of finding are arranged in the vertical frames 15 and 20.

  In the opening device 1, the position indicated by B is arranged on the outer side in the finding direction than the position indicated by A. Thereby, the door-end fences 50 and 80 are concealed from the indoor front view in the closed posture of the opening device 1. Here, the position of B is located outside the position of A in the direction of finding, but this is flush (the same position), or the position of B is slightly located in the direction of finding than the position of A if slightly. You may arrange | position inside. Specifically, it is preferable that 90% or more of the size in the direction in which the door toe is found is concealed.

  In the opening device 1, as described above, the wrinkles are formed thin. Therefore, heat transfer through the ridge can be suppressed. In addition to this, the eaves 50 and 80 in which the heat transfer is thus suppressed are concealed from the room view by the cover member. Thereby, heat transfer between the bag and the room can be suppressed, and the heat insulation performance can be further improved.

By adopting such a structure, both the frame and the ridge are of a bridge material method like a conventional heat insulating sash (a method of dividing the frame and ridge into an indoor side member and an outdoor side member and connecting them with a resin or the like). Even without using, it is possible to improve the heat insulation performance. That is, the heat insulation performance can be improved with a simple configuration. However, this does not prevent the application of the bridge method, and a bridge structure may be used. This is because further improvement in heat insulation can be expected.
With such a configuration, when a conventional opening device is installed in an opening of a certain size, H-3 grade (JIS A 4706, JIS A 4702, thermal flow resistance 0.287 m ² · K / W or more) Even if the heat insulation performance cannot be obtained, according to the opening device 1, the heat insulation performance of H-3 grade can be obtained.

  In addition, since the wrinkles are formed thin as described above and the wrinkles are concealed when viewed indoors, the appearance is excellent. Here, since the cover members 18 and 22 may be formed so as to hide the thin ridges, the dimensions of the cover members 17 and 18 indicated by E in FIG.

The shoji 40 of the opening device 1 can be manufactured as follows, for example. That is, the spacers 44 are arranged so as to be sandwiched between the two glass plates 42 and 43 slightly inside the end surfaces of the glass plates 42 and 44. Then, a material that becomes the sealing material 45 is filled in the space outside the spacer 44 between the plate glasses 42 and 43. As described above, in the present embodiment, the two glass sheets are used. However, the present invention is not limited to this and may be more than two.
Next, the outer peripheral tape 48 is wound along the end surface of the multilayer glass panel 41 while the filled sealing material has fluidity. And while the filled sealing material has fluidity, the glazing channel 60 is disposed so as to cover the end of the multilayer glass panel 41. At this time, the protrusion 64 of the glazing channel 60 penetrates the outer peripheral tape 48 and enters the seal material 45.

  The outer peripheral part of the multilayer glass panel 41 to which the glazing channel 60 is attached is assembled so as to be inserted into vertical and horizontal ridges (50, 51, 52, 53).

  In the opening part apparatus 1 of this embodiment, it is necessary to take a glazing channel while the sealing material has fluidity. Therefore, the glazing channel may be soiled by the sealing material during installation. However, the contamination can be prevented by arranging the outer peripheral tape as in the present embodiment. Further, since the sealing material can be prevented from flowing out by the outer peripheral tape, the manufacturing process can be advanced without waiting for the sealing material to harden.

Here, as described above, the protruding portion 64 of the glazing channel 60 needs to finally penetrate the outer peripheral tape 48. That is, the slit 48a of the outer peripheral tape 48 is finally formed by any means. The means for this is not particularly limited. For example, before the outer peripheral tape 48 is wound along the outer peripheral end surface of the multilayer glass panel 41, slits are cut in advance on the outer peripheral tape 48 by a cutter or the like. It can be mentioned that a penetrating means such as a perforation or a perforation is provided.
Alternatively, after the outer peripheral tape 48 is wound along the outer peripheral end surface of the multilayer glass panel 41, a slitting cut is made on the outer peripheral tape 48 with a cutter or a perforation means such as a perforated cut is provided. Also good.
In addition, the outer peripheral tape may be made of a material that tears and penetrates the outer peripheral tape by pressing the protruding portion of the glazing channel against the outer peripheral tape.

Next, a modification regarding the form of the glazing channel will be described. The other parts are the same as those of the opening device 1 described above, and thus the description thereof is omitted.
FIG. 6A is a cross-sectional view of a glazing channel 160 used in an opening device according to one modification. The glazing channel 160 is different from the glazing channel 60 in that the protrusion 164 has two of the first protrusion 164a and the second protrusion 164b. This further strengthens the fixation between the sealing material and the glazing channel.

  FIG. 6B is a diagram showing a cross-sectional view of the glazing channel 260 used in the opening device of another modified example. The glazing channel 260 is characterized in that the protruding portion 264 is provided separately. A piece 161 that forms a U-shaped bottom of the glazing channel 260 is provided with a slit 161a, and the protruding portion 264 can protrude inside the U-shape so as to penetrate therethrough. According to this, it is possible to attach a necessary portion without excess or deficiency to a portion requiring strength.

  FIG. 7 is a view for explaining an opening device 201 according to a reference embodiment, and corresponds to FIG. The opening device 201 is different from the opening device 1 in the manner of the door guards 250 and 280 of the external shoji 240 and the inner shoji 270. Since the other configuration is the same as the description of the opening device 1, the reference numerals are also common and the description is omitted.

  The door toe fences 250 and 280 of the opening device 201 are not concealed in the room view even when the shoji 240 and 270 are closed. Specifically, the door toe fences 250 and 280 are not concealed by the cover members 18 and 22 by the size indicated by Y in FIG.

This is because, for example, since the heel is long in a large opening device, it is necessary to increase the thickness of the heel from the viewpoint of securing its strength (out-of-plane strength), or from the viewpoint of operability. For example, it is necessary to provide a handle (grip) on the tip.
Even in such a case, since the double-glazed glass panel and the glazing channel are fixed in the same manner as described above, the wrinkles can be formed thinner than in the prior art. Thereby, even if the portion indicated by Y in FIG. 7 is not concealed by the cover members 18 and 22, the heat insulation can be improved as compared with the conventional case.
However, if the size of Y is too large, the degree of improvement in the heat insulation performance will be reduced. Therefore, (X−Y) / X × 100% of the thickness of the ridge shown by X in FIG. It is preferable that it is 60% or more.
For example, when a conventional opening device is installed in an opening of a certain size, the heat insulation performance of H-3 grade (JIS A 4706, JIS A 4702, thermal flow resistance 0.287 m ² · K / W or more) Even if it cannot be obtained, according to the opening device 201, it may be possible to obtain H-3 grade heat insulation performance.

  While the invention has been described in connection with embodiments that are presently practical and preferred, the invention is not limited to the embodiments disclosed herein, The invention can be changed as appropriate without departing from the scope or spirit of the invention that can be read from the entire scope and specification, and an opening device with such a change must also be understood as being included in the technical scope of the present invention. Don't be.
