Abstract

PROBLEM TO BE SOLVED: To prevent dew condensation by providing a sticking means on a base material composed of a foaming sheet body of resin, and setting a thickness of the base material including the sticking means not more than a specific value. SOLUTION: A pressure sensitive adhesive 3 is applied to one surface of a tape-like base material 2 composed of a foaming body sheet of resin to obtain a sheet insulating tape 1. When using a weak pressure sensitive adhesive of an acrylic resin as the pressure sensitive adhesive 3, there is practically no paste remainder on the frame surface side of a sash frame. A sucking tape forming innumerable microscopic bubbles in a soft resin base material may be separately stuck to the base material 2 instead of the pressure sensitive adhesive 3. Since these bubbles play a role of a sucker, sucking force is recovered by cleaning a sucking surface, so that the tape can be reused. While a width of the heat insulating tape 1 is set in the almost the same as a sash frame width, a thickness T of the heat insulating tape is set not more than 3 mm. Thus, when sliding one sash frame in the opening direction, the heat insulating tape 1 does not contact with a part (the inside) overlapping with the other slide frame, and does not peel off.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating tape for a sash frame which is attached to a sash frame fitted in a window of a house or an office building.

[0002]

2. Description of the Related Art Air conditioners (commonly known as air conditioners)
When the living space or office space is maintained at a predetermined temperature, from the viewpoint of energy saving, doors and windows are closed so as not to release the heat as much as possible, but the heat still escapes from the room. Although the heat loss due to the opening and closing of the doors to and from which people enter and exit can not be helped, the heat loss through the window portion is as large as otherwise. Therefore, conventionally, a window glass for shielding heat rays is used, or a heat insulating sheet is attached to the window glass.

[0003]

However, that is not enough. The present inventor measured the amount of heat conduction around the glass part of the window and the sash frame, although there is a slight difference depending on the material, of the total amount of heat exchanged between indoor and outdoor in the window part, The result was that the glass part was about 56%, and the sash frame etc. other than the glass part was about 44%. Therefore, about half of the amount of heat around the window is transmitted outside the glass part and is released to the outside.

Accordingly, the applicant has provided a heat insulating sheet for window glass. In this method, a transparent heat insulating sheet is adhered to the entire surface of the window glass to insulate the heat. However, as described above, a sufficient heat insulating effect is obtained because about half of the heat enters from outside the glass part. It turned out that it was not done.

This is due to the difference in the thermal conductivity λ between the glass and the sash frame. The thermal conductivity of _glass λ _glass is λ
_{While glass} = 0.78 W / m · K, the thermal conductivity λ of aluminum, which is a general sash constituent material,
_Aluminum has λ _aluminum = 210 W / m · K, and conducts heat approximately 270 times better than glass. It can be said that the above result was obtained from this value.

Also, the thermal conductivity of water contained in air λ _water
Is λ _water = 0.6 W / m · K, and the thermal conductivity λ of air is
_Air is about 30 times larger than 0.02 W / m · K. Therefore, the moisture in the air is attracted to a material having a higher thermal conductivity, that is, a glass window or a sash frame in the room. The result is condensation.

[0007] When dew condensation occurs indoors, there have been problems such as the growth of fungi such as molds and the permeation of wood and tatami mats around the sash frame attached to the sash frame, causing them to rot.

One method of solving this problem is to double the sash frame. The sash frame is formed of a metal frame on the outside (outdoor side) and a resin frame on the inside (indoor side) of the sash frame, and the sash frame is formed by combining them. That is.

[0009] However, this method must be exchanged from the sash frame and the base frame holding the sash frame, and is an effective method for newly constructing or remodeling a house. Replacing and using is expensive and impractical.

[0010]

SUMMARY OF THE INVENTION Therefore, the present invention has been made as another method for preventing dew condensation based on the above experimental results, and its object is to provide a contact between a sash frame and air, that is, An object of the present invention is to provide a heat insulating tape for a sash frame in which the surface is covered with a heat insulating material so that heat conduction is less likely to occur, thereby improving the indoor heat insulating effect and, as a result, preventing condensation.

In order to achieve the above object, the present invention provides a base material which is made of a resin foam sheet and has a width substantially equal to the width of a sash frame for holding a glass window or the like; And a sticking means provided, wherein the thickness of the base material including the sticking means is set to 3 mm or less.

With this arrangement, the heat insulating tape is adhered to the sash frame of the sliding door, and when one of the sash frames is slid in the opening direction, a portion (inside) overlapping the other slide frame is insulated. The tape does not touch and does not peel off.

As the above-mentioned sticking means, first, an adhesive can be used. In this case, it is more preferable to use, for example, a weak adhesive such as an acrylic adhesive, and according to this, there is almost no residue on the sash frame.

Further, as the above-mentioned attaching means, it is possible to use a suction tape having a large number of micro suction cups made of micro foam. According to this, the adhesive force can be recovered by cleaning the suction surface of the suction tape, and the tape can be reused.

[0015] In the present invention, it is preferable that a heat reflecting sheet made of a metal foil such as aluminum is provided between the base material and the bonding surface of the base material. By reflecting light, the heat insulating effect can be enhanced.

[0016] At least one along the longitudinal direction of the substrate.
It is one of the features of the present invention to provide a cut in the book,
According to this, when the frame width of the sash frame is narrow, it can be cut to an arbitrary width for use.

[0017]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a heat insulating tape for a sash frame according to an embodiment of the present invention, and FIG. 2 is a partial sectional view thereof. The heat insulating tape 1 has a tape-shaped substrate 2 made of a resin foam sheet, and an adhesive 3 provided on one surface of the substrate 2, and a roll core such that the adhesive 3 is on the inside. A plurality of predetermined lengths are wound around R.

The substrate 2 is a heat-insulating resin sheet made of, for example, foamed polyethylene or the like. Inside the substrate 2 are formed numerous bubbles (not shown). The base material 2 is generally white, which is the ground color of the resin. However, considering the basicity of the resin with the sash frame, the base material 2 may be mixed with a pigment and colored in an arbitrary color.

In this embodiment, an auxiliary film 2a made of a thin and flexible polyethylene film is integrally attached to one surface of the substrate 2 by, for example, heat sealing. The pressure-sensitive adhesive 3 is a pressure-sensitive adhesive made of, for example, an acrylic resin, and is uniformly applied on the auxiliary film substrate 2a. The pressure-sensitive adhesive 3 is preferably an acrylic pressure-sensitive adhesive as described above, and particularly preferably has a low tackiness. According to this pressure-sensitive adhesive, even if the pressure-sensitive adhesive is adhered to the sash frame, it remains on the sash frame surface side. rare. In this embodiment, the auxiliary film 2a is bonded to the base material 2. However, the auxiliary film 2a may be omitted and the adhesive may be applied directly on the base material 2.

As a means for attaching the base material 2 instead of the adhesive 3, a suction tape made of an acrylic resin or the like may be separately attached to the base material 2. In the suction tape, countless micro-bubbles are formed on a soft resin base material, and these bubbles serve as a suction cup. When this suction tape is used, the suction force is recovered by flushing the suction surface with water or the like, and the tape can be reused.

In this embodiment, when the tape width is W and the tape thickness is T, the tape width W = 40 mm and the tape thickness T are set to 3 mm or less. The tape width W is preferably about 40 mm because the width of a typical sash frame (per section: 90 cm wide × 180 cm high (3 × 6)) is about 40 mm. The tape width W can be arbitrarily selected according to the frame width of the sash frame.

By setting the tape thickness T to 3 mm or less, when the heat insulating tape 1 is mounted on the sash frame of the sliding door, when one sash frame is slid, the door stop side of the other sash frame and In order to enter the gap (inside) on the opposite door stop side, it is preferable to set in this way. Here, the tape thickness T is a thickness including the sticking means such as the above-mentioned pressure-sensitive adhesive or suction sheet.

Next, FIG. 3 shows a partial cross-sectional view of another embodiment of the heat insulating tape for a sash frame of the present invention. This insulation tape 1
a has substantially the same configuration as that of the first embodiment, and a heat reflection sheet 4 made of a thin film of a metal material is provided between the base material 2 and the adhesive 3 or the suction tape.

The heat reflecting sheet 4 is made of a metal material such as aluminum, and is made of a material which reflects light due to metallic luster or a material which easily absorbs and emits heat due to high thermal conductivity. In addition, any material other than the metal material can be selected as long as it has the above-described effects.

Further, in this case, the heat reflection sheet 4 is provided on the adhesive surface side of the substrate 2, but the heat reflection sheet 4 is provided on both sides.
May be provided. By attaching the heat insulating tape thus formed to the outside (outdoor side) sash frame, heat insulation is performed while reflecting light, so that the heat insulating property can be further improved.

, The heat insulating tapes 1 and 1a are made of two sash frames S
It is attached to the sliding door D consisting of 1 and S2. Here, the heat insulating tapes 1 and 1a are basically attached only to the indoor side frame surface of the sliding door D.

The sash frames S1 and S2 are composed of four outer frame frames F1, F2, F3 and F4, and are assembled in a rectangular shape by connecting their ends. Outer frame F1,
Glass plates G whose outer peripheral edges are held are held at F2, F3, and F4.

First, the outer frames F1, F2, F
The heat insulating tapes 1 and 1a are cut to an arbitrary length according to the frame length of F3 and F4. Next, the outer frame F1, F

But the thickness T of the heat insulating tapes 1 and 1a is T ≦ T
Since it is 3 mm, it does not peel off from the frame frames F1 and F2 when the sliding door D is opened.

In this manner, the exposed portions of the sash frames S1 and S2 other than the glass plate G can be covered with the heat insulating tapes 1 and 1a. With this configuration, the contact portion between the air and the frame is sealed by the heat insulating material, so that the above-described heat conduction hardly occurs, that is, dew condensation does not occur.

In this embodiment, the heat insulating tapes 1 and 1a are attached to the sash frame for holding the glass window. However, the heat insulating tape of the present invention is attached to the base frame for holding the sash frame in a slidable manner. A tape may be attached, and in this way, heat entering from the base frame can be insulated.

The simplest form of the heat insulating tapes 1 and 1a is to attach them to the sash frames S1 and S2 using one tape as shown in FIG. As shown in FIG. 5, a cut 5 may be provided in advance along the longitudinal direction of the heat insulating tapes 1 and 1a.

In this way, the user can insulate the heat insulating tapes 1, 1 along the cuts 6 according to the width and shape of the sash frame.
a, the base material 2 becomes narrow base materials 2a, 2a.
a can be divided into, for example, half a half (about 90 cm × about 9
(0 cm).

Further, along the cut 5, the heat insulating tapes 1,
As shown in FIG. 6, the heat insulating tapes 1 and 1a are bent so as to cover the corners C of the sash frame S.
Can be attached, and the frame can be covered three-dimensionally. Such an embodiment is also included in the present invention.

Here, in this embodiment, the cut 5 is
Although one tape is formed for the heat insulating tapes 1 and 1a, a plurality of tapes may be provided, and such an embodiment is also included in the present invention. Further, the cuts 5 may be provided not only in the longitudinal direction but also in the width direction, or may be provided in a lattice shape in both the longitudinal direction and the width direction.

[0036]

As described above, the heat insulating tape for a sash frame of the present invention has the following effects. By the thickness of the heat insulating tape including the attaching means is 3 mm or less,
When one of the sash frames is slid in the opening direction, the heat insulating tape does not come into contact with a portion (inside) overlapping with the other slide frame and does not peel off.

As the first attaching means to the sash frame,
Since the weak adhesive of the acrylic resin is used, there is almost no residue on the frame surface side of the sash frame. By using a suction tape having a large number of micro suction cups as the second attaching means, the adhesive force can be recovered by cleaning the suction surface of the suction tape, and the tape can be reused. By providing the heat reflecting sheet between the base material (foam sheet) and the attaching means, the heat insulating effect can be further enhanced.

Further, by providing cuts along the longitudinal direction of the heat insulating tape, the user can cut or bend the sash frame to an arbitrary width depending on the frame width.
