DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-shaped member mounting device for mounting another plate-shaped member to a plate-shaped member for closing a window or an entrance, for example, and a plate-shaped member mounting structure.

[0002]

2. Description of the Related Art Conventionally, the mainstream is to attach a window glass to a window frame in a single layer. However, in order to improve the heat insulating property and the soundproofing property, as shown in the vertical sectional view of FIG.
The window panes 1 and 2 may be doubled and attached to the window frame 3. In the window glass mounting structure shown in FIG. 3, the first window glass 1 is mounted on the window frame 3 via the glazing channel 4. The second window glass 2 is attached to the glazing channel 4 via a fixing clip 5 and an attachment 6.

The fixed clip 5 has an upper end 5a shown in the figure sandwiched between the first window glass 1 and the glazing channel 4, and has an engaging portion 5b at the lower end. The attachment 6 includes a holding portion 6a for holding a peripheral portion of the second window glass 2, and an engaged portion 6b. By engaging the engaged portion 6b with the engaging portion 5b, the second
Window glass 2 can be mounted with a predetermined distance from the first window glass 1. 7 shown in FIG. 3 is a spacer. The spacer 7 is for forming a predetermined gap 8 between the first and second window glasses 1 and 2. The spacer 7 is made of butyl rubber in which a desiccant is dispersed and mixed, and absorbs moisture existing in the gap 8 formed between the first and second window glasses 1 and 2. Then, the air in the gap 8 is dried. When the spacer 7 is bonded to the engaged portion 6b or the second window glass 2 with an adhesive,
The engaged portion 6b to which the window glass 2 is attached is engaged with the engaging portion 5b.

However, in the conventional window glass mounting structure shown in FIG. 3, the spacer 7 bonded to the engaged portion 6b or the second window glass 2 with an adhesive is used.
However, dropping from the engaged portion 6b or the second window glass 2 due to, for example, aging of the spacer 7 and the adhesive or opening and closing operations of the glass doors provided with the window glasses 1 and 2. There is a problem that the appearance is poor. Then, the first window glass 1 and the second window glass 2
Since the gap 8 between the first and second window glasses 1 and 2 cannot be absorbed when the moisture absorbing power of the desiccant decreases, the moisture flowing into the gap 8 cannot be absorbed. Condensation may occur on the inner surface on the side of the gap 8.

[0005] The present invention is to prevent the desiccant, which is disposed between, for example, a double-plate member for closing a window and an entrance, from dropping off, and that the first and second plate members face each other. It is an object of the present invention to provide a plate-shaped member mounting tool and a plate-shaped member mounting structure capable of preventing the occurrence of dew condensation on the inner surface.

A second window glass 10 is attached to the left side (indoor side) of the left glass door 12 shown in FIG. 1A, and the second window glass 10 is attached to the right side (outside side) of the right glass door 12. Window glass 1
0 is attached. Thus, both glass doors 1
The second window glass 10,
10 are attached, so that both second windowpanes 1
0 and 10 are prevented from contacting each other. Since the left and right plate-like member mounting structures are the same,
The same parts are indicated by the same reference numerals in the drawings, and the right plate-shaped member mounting structure is described, and the description of the left plate-shaped member mounting structure is omitted.

The right glass door 12 has a vertically long rectangular transparent first window glass 9. The first window glass 9 has a corresponding recess provided on the upper window frame 18a, the lower window frame 18b, the left window frame 18c, and the right window frame 18d (window frame 18), each of which has a bar-shaped periphery. In this state, the upper window frame 18a, the lower window frame 18b, the left window frame 18c, and the right window frame 18d adjacent to each other are connected to each other. The second window glass 10 is a vertically long rectangular transparent glass plate smaller than the first window glass 9. The second windowpane 10 has corresponding concave grooves provided on the upper frame 11a, the lower frame 11b, the left frame 11c, and the right frame 11d (frame 11), each of which has a bar-shaped periphery. The upper frame 11a, the lower frame 11b, the left frame 11c, and the right frame 11d adjacent to each other in this state are connected to each other.

The upper frame member 11a, the lower frame member 11b, the left frame member 11c, and the right frame member 11d are made of, for example, aluminum, and have the same sectional shape as shown in FIG. Needless to say, the material may be, for example, made of synthetic resin instead of aluminum. Upper frame 11a and lower frame 11
b have the same length, and the left frame 11c and the right frame 11
The length of d is the same. FIG. 2 is a diagram showing a cross section of the upper frame 11a. On the left side of the lower surface of the upper frame 11a, a second
A concave groove 20 for fitting the upper edge of the window glass 10 is provided along the length direction of the upper frame 11a. The upper edge of the second window glass 10 is fitted into the concave groove 20,
The fitting portion is hermetically sealed with, for example, a caulking material or the like (not shown). Similarly, the lower frame 11b,
The corresponding edges of the second window glass 10 are fitted in the respective concave grooves 20 of the left frame 11c and the right frame 11d, and the fittings are hermetically sealed with a caulking material or the like. is there. A desiccant storage chamber 22 for storing the desiccant 21 is provided inside the right side of the lower surface of the upper frame 11a along the length direction of the upper frame 11a. The desiccant storage chamber 23 forms the desiccant storage chamber 22. The cross-sectional shape of the desiccant storage chamber 22 is substantially elliptical as shown in FIG. 2, and opens toward the lower space 24. This opening is the communication hole 25. The space 24 is a space formed between the first and second window glasses 9 and 10. Similarly, each of the desiccant storage chambers 22 provided in the lower frame 11b, the left frame 11c, and the right frame 11d is also provided with a communication hole 25 that opens toward the space 24. As the desiccant 21, for example, solid silica gel, synthetic crystalline zeolite, anhydrous calcium sulfate, or the like can be used.

As shown in FIG. 2, each communication hole 25 has a width A perpendicular to the length direction of the frame 11 of about 3.8 mm, and is accommodated in the desiccant accommodating chamber 22. The diameter is smaller than the diameter B (≒ 5 mm) of the substantially spherical desiccant 21. Thereby, the desiccant holding unit 23 can hold the desiccant 21 stored in the desiccant storage chamber 22 so as not to be separated outside (inside the space 24) through the communication hole 25. Also, as shown in FIG. 2, the first frame 11a of the upper frame 11a, the lower frame 11b, the left frame 11c, and the right frame 11d.
Each side surface 26 that is in close contact with the window glass 9 is parallel to the second window glass 10 fitted into the groove 20. Each side surface 26 and the surface of the first window glass 9 are adhered by, for example, an adhesive, and the contact surfaces are hermetically sealed by, for example, a caulking material. Furthermore, the first window glass 9, the second window glass 10, the upper frame 11a, the lower frame 11b, the left frame 1
The inside space 24 formed by 1c and the right frame 11d is almost evacuated of air and has a pressure lower than the atmospheric pressure. As a method of bleeding the air in the space portion 24, for example, when the frame 11 to which the second window glass 10 and the desiccant 21 are attached is bonded to the first window glass 9, The air in the space 24 is heated from the outside of the window glasses 9 and 10, and heated and dried, and the expanded air is supplied into the space 24. When the temperature of the air in the space 24 reaches a predetermined temperature of, for example, about 90 ° C., the frame 11 is bonded to the first window glass 9 to seal the space 24. As a result, when the temperature of the air in the space 24 decreases to room temperature, the pressure of the air in the space 24 decreases to a predetermined pressure, and the air in the space 24 is reduced.

According to the plate-like member mounting structure configured as described above, the glass door 12 has a double structure with the first window glass 9 and the second window glass 10 provided in parallel with each other at a predetermined interval. Since the space portion 24 is provided between the first window glass 9 and the second window glass 10, the heat insulating effect and the soundproofing of the glass door 12 are reduced by the second window glass 1.
This can be improved over the case where only the first window glass 9 having no 0 is provided. Then, the second window glass 10 can be attached to the first window glass 9 by attaching the frame 11 to which the second window glass 10 has been attached to the first window glass 9. There is no need to change the structure, the construction is simple, and the cost is low. Further, the space 24 formed between the first and second window glasses 9 and 10 is hermetically sealed, and the pressure is lower than the atmospheric pressure, so that the amount of moisture in the space 24 is reduced. Can be reduced. As a result, the first and second
Dew condensation can be prevented from occurring on the inner surface of the window glasses 9 and 10 facing the space portion 24 side. Furthermore, even if moisture remains in the hermetically sealed low-pressure space 24, the moisture can be absorbed by the desiccant 21 and the space 24 can be almost completely dried. It can be maintained in a state. Therefore, the first and second
The formation of dew condensation and mold due to the attachment of water droplets to the inner surface of the window glasses 9 and 10 facing the space 24 can be reliably prevented.

The desiccant storage chamber 22 formed by the desiccant storage section 23 has a structure in which the desiccant 21 is stored and held therein. The communication hole 25 connects the desiccant storage chamber 22 and the space 24. Is smaller in size than the desiccant 21, so that the first and second
The opening and closing operation of the glass door 12 provided with the window glasses 9 and 10 can surely prevent the desiccant 21 from detaching from the desiccant holding part 23. in this way,
The desiccant 21 drops off from the desiccant holding part 23 and the space 24
Since the glass door 12 does not move inside, the appearance of the glass door 12 can be prevented from being deteriorated by the desiccant 21 that has fallen off.

Further, the second window glass 10 is fitted in the concave groove 20 of each frame 11, and the desiccant 21 is held by the desiccant holding portion 23 of each frame 11, Can be attached to the first window glass 9 by bonding, so that the second window glass 10 and the desiccant 21 can be relatively easily attached to the first window glass 9 via the frame 11. . Therefore, the work for attaching the second window glass 10, the desiccant 21, and the frame 11 to the first window glass 9 can be reliably performed in a short time.

However, in the above embodiment, the first and second
Although the window glasses 9 and 10 are made of transparent plate glass, other than this, an anti-transparent or opaque plate glass may be used. In addition to the plate glass, for example, a plastic or metal plate may be used. And in the said embodiment, although the plate-shaped member mounting structure was shown in the example applied to the glass door 12 of the glass window, it is not shown in the figure, but it may be applied to the door or door provided at the entrance. Good. In the above embodiment, the communication hole 25 is made smaller than the desiccant 21 so that the desiccant 21
Is prevented from moving into the space 24 through the communication hole 25. Instead, the communication hole is formed in a shape larger than the desiccant 21, and the communication hole is closed by a lid having a ventilation hole. Is also good. This vent is smaller in size than the desiccant 21.

[0024]

According to the plate-like member mounting device and the plate-like member mounting structure of the present invention, the first plate-like member and the second plate-like member, for example, a door or a door for closing a window or an entrance are provided. Since the space formed between them can be sealed, moisture existing in the sealed space can be absorbed by the solid desiccant, thereby maintaining the space in a dry state. Can be done. Accordingly, it is possible to prevent the occurrence of dew condensation and mold due to the attachment of water droplets to the inner surface of the first and second plate members facing the space.
Since the solid desiccant is held by the desiccant holding part, the solid desiccant is detached from the frame due to aging of the desiccant or the opening and closing operation of the first and second plate members. It does not look good.

According to the plate-like member mounting device of the third invention, the desiccant is stored and held inside the desiccant holding portion, and the inside of the desiccant holding portion communicates with the space. Since the communication hole is smaller in size than the desiccant, the desiccant is stored in the desiccant holding unit by the secular change of the desiccant or by the opening and closing operation of the door provided with the first and second plate members. Can be reliably prevented from falling off.

According to the plate-like member mounting device of the fourth invention, the second plate-like member is fitted in the concave portion of the frame, and the desiccant is held in the desiccant holding portion of the frame. Since the frame can be attached to the first plate-shaped member, the second plate-shaped member and the desiccant can be easily attached to the first plate-shaped member via the frame. Therefore, the work for attaching the second plate-shaped member, the desiccant, and the frame to the first plate-shaped member can be performed in a short time and reliably.

According to the plate-like member mounting structure of the fifth invention, the same effects as those of the plate-like member mounting tools of the first to fourth inventions can be obtained. Then, the space formed between the first and second plate-shaped members is set at a pressure lower than the atmospheric pressure to reduce the amount of moisture in the space. It is possible to prevent dew condensation from occurring on the inner surface of the plate-shaped member facing the space.
