Abstract

PROBLEM TO BE SOLVED: To provide a heat insulating frame and a heat insulating sash capable of promoting dew proofing efficiency and preventing deflection of a heat insulating cover. SOLUTION: A sill 12 and jams 13 as a heat insulating frame of a window frame 10, mounting pieces 120A and 130A of frame main bodies 120 and 130 are formed in notch sections 136 (illustrated only for the jambs 13). Accordingly, the contact area of heat insulating covers 32 and 33 with the mounting pieces 120A and 130A can be narrowed, and the transfer of heat can be reduced by its factor to prevent the occurrence of condensation. Since the heat insulating covers 32 and 33 can be reinforced by reinforcing sections 137 (illustrated only for the jambs 13) other than the notch sections 136, the deflection of the heat insulating covers 32 and 33 can be prevented, and the strength can be ensured.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a heat insulating frame and a heat insulating sash, and more particularly, to a heat insulating frame and a heat insulating sash used for a sliding window and a sliding window.

[0002]

2. Description of the Related Art A window frame in a general sash is constituted by an upper frame, a lower frame, and a vertical frame made of metal such as aluminum having high thermal conductivity. Since such a window frame is made of metal, heat is easily transmitted between the inside and outside of the room, and when the temperature difference between the inside and outside is large, dew condensation occurs on the indoor surface of the window frame.

[0003] For this reason, the indoor exposed surface, which is exposed to the indoor side when the shoji is closed in the window frame, is covered with a heat-insulating cover having low thermal conductivity, such as resin, so that the metal window frame is directly connected to the indoor side. Insulation frames have been developed that prevent exposure to the air and thereby reduce the occurrence of condensation.

[0004]

However, in a portion of the heat insulating cover that is in close contact with the metal window frame, for example, in a portion of the heat insulating cover that is in close contact with the mounting piece portion of the window frame, the temperature in the winter night or indoor and outdoor conditions is low. When the difference is large, the heat insulating cover is cooled by the metal window frame, and the cooled heat insulating cover may come into contact with the warm air in the room, resulting in dew condensation. On the other hand, if the mounting piece that is in close contact with the heat-insulating cover is eliminated in the window frame, the heat-insulating cover cannot be reinforced with the mounting piece, and the heat-insulating cover bends and cannot be accurately arranged. was there.

An object of the present invention is to provide a heat insulating frame and a heat insulating sash which can improve the dew-proof performance and prevent the heat insulating cover from bending.

[0006]

According to the present invention, there is provided a frame body having at least a portion formed of metal, and a heat-insulating cover mounting piece of the frame body to cover an indoor-side exposed surface of the frame body. A heat insulating frame comprising a heat insulating cover, wherein a cutout portion is formed in the heat insulating cover mounting piece.

In such a heat-insulating frame, the notch is formed in the heat-insulating cover mounting piece of the frame main body, so that the contact area between the heat-insulating cover and the mounting piece, that is, the frame main body can be reduced. Conduction is reduced, and the occurrence of dew condensation can be suppressed. Further, since the heat insulating cover can be reinforced at a portion other than the cutout portion of the heat insulating cover mounting piece, it is possible to prevent the heat insulating cover from bending and secure the strength.

Further, the frame main body is composed of a non-ferrous metal indoor member and an outdoor member, and a heat insulating member connecting the indoor and outdoor members, and the heat insulating cover mounting piece is formed on the indoor member. Is preferred.

When such a window frame is used, since the heat insulating member is interposed between the indoor and outdoor members, heat conduction between the indoor and the outdoor can be reduced, and the heat insulating performance and the dew-proof performance can be improved. Also,
If the heat insulating cover mounting piece is formed on the indoor member,
Since the heat transmitted from the outdoor to the heat-insulating cover mounting piece is small, the heat conduction to the heat-insulating cover in contact with the heat-insulating cover mounting piece can also be reduced. For this reason, the dew-proof performance in the heat insulating cover portion can be further improved.

[0010] It is preferable that the notch is formed except at least an end of the heat insulating cover mounting piece. According to such a configuration, in the window frame, the upper and lower frames and the vertical frame are butted and joined to each other. For this reason, if the end of the heat insulating cover mounting piece is notched, a gap is formed in the cutout when the frame is joined to another frame, and the sealing performance and the like of the joint surface deteriorate. On the other hand, if the notch is formed except for the end of the heat-insulating cover mounting piece, no gap is formed in the joint portion of the frame, and the sealing performance can be improved.

It is preferable that the notch is formed except at least a portion where a fixing member for fixing the heat insulating cover to the frame body is provided. If a notch is formed in the part where the fixing member such as a screw is provided,
Screws and the like cannot be screwed and fixed to the heat insulating cover mounting piece, and a bracket or the like must be separately used. On the other hand, if the notch portion is formed except for the portion where the fixing member is provided as in the present invention, the fixing member such as a screw is directly screwed into the mounting piece portion, and the heat insulating cover is made to have a heat insulating property. It can be fixed to the cover mounting piece, the fixing structure can be simplified, and the assembling workability can be improved.

It is preferable that the notch is formed except for at least a portion to which the frame attachment member is attached. With this configuration, the operator handle,
A frame attachment member, such as a cam latch handle receiving member, attached to the window frame can be directly attached to the heat insulating cover attachment piece, so that the attachment structure can be simplified and the assembling workability can be improved.

Further, the notches may be formed at regular intervals along the longitudinal direction of the frame. If the cutouts are formed at regular intervals, the reinforcing portions of the heat-insulating cover are also provided at regular intervals, so that bending of the heat-insulating cover and the like can be effectively prevented, and dew-proofing performance and heat-insulating performance can be improved.

A heat insulating sash according to the present invention comprises a window frame in which an upper frame, a lower frame and left and right vertical frames are framed four times, an upper frame, a lower frame and left and right vertical frames are framed into a four-frame frame, and a screen is incorporated. Wherein at least one of the frames of the window frame is the heat insulating frame according to any one of claims 1 to 6. .

Also in such a sash, since the heat insulating frame in which the notch is formed in the heat insulating cover mounting piece is used, the contact area between the heat insulating cover and the mounting piece, that is, the frame body can be reduced. In addition, heat conduction is reduced, and the occurrence of dew condensation can be suppressed. In addition, since the heat insulating cover can be reinforced at a portion other than the cutout portion of the heat insulating cover mounting piece,
Bending of the heat insulating cover can be prevented, and strength can be secured.

It is preferable that the lower frame of the window frame is the heat insulating frame. Furthermore, if the upper and lower frames and the vertical frame are heat insulating frames each having the cutout, the dew-proof performance can be further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a partial cross section showing a window frame 10 of a vertical sliding window (insulating sash) 1 according to the present embodiment, FIG. 2 is a vertical sectional view of the vertical sliding window 1, and FIG.
It is a cross-sectional view showing the main part. In addition, in each drawing, hatching showing a cross section is omitted in the main constituent members in order to make the drawing easy to see.

The vertical sliding window 1 is composed of the window frame 10 attached to the opening of the building, and a sliding door 20 which is openably and closably disposed in the window frame 10 via upper and lower hinges 2. .

The window frame 10 has a configuration in which an upper frame 11, a lower frame 12, and left and right vertical frames 13 are framed four times. Each frame 1
1, 12, 13 are heat insulating cover mounting pieces 11 on the indoor side.
Frame bodies 110, 12 provided with 0A, 120A, 130A
0, 130, and mounting pieces 110A, 120A, 130A
And heat-insulating covers 31, 32, 33 made of resin having low thermal conductivity and covering the indoor-side exposed surfaces of the frame main bodies 110, 120, 130, each of which forms a heat insulating frame. ing.

Of the frame main bodies 110, 120 and 130, the upper frame main body 110 and the vertical frame main body 130 having high thermal conductivity are:
The lower frame body 120 is made of a normal aluminum extruded shape.
Is an insulating member formed of an indoor member 121 made of a metal having a high thermal conductivity, that is, an extruded member made of aluminum, an outdoor member 122, and a heat insulating member 123 made of a resin having a low thermal conductivity connecting these members. The heat insulating performance is further enhanced by attaching the heat insulating cover 32 to the mounting piece 120A provided on the interior member 121 of the housing.

In this embodiment, the heat insulating member 123 of the lower frame main body 120 is formed by injection of urethane resin or the like. As the heat insulating member, for example, caulking is performed between a metal indoor member and an outdoor member. A plate member made of a synthetic resin fixed by, for example, may be used. Further, as the upper frame main body 110 and the vertical frame main body 130, a heat-insulated profile like the lower frame main body 120 may be adopted, and further, the lower frame main body 120 may be a normal aluminum extruded profile. Frame body 110, 1
The structure of 20, 130 is arbitrary.

The shoji screen 20 is formed by assembling an upper frame 21, a lower frame 22, and left and right vertical frames 23 into a four-frame frame.
It is a configuration incorporating. Each of the frames 21, 22, 23 covers a frame body 210, 220, 230 made of a metal, ie, an extruded member made of aluminum having a high thermal conductivity, and an indoor exposed surface of the frame bodies 210, 220, 230. Heat-insulating cover 4 made of resin having low thermal conductivity
1, 42, and 43, each of which is an insulating frame. A cam latch handle (not shown) that is operated to open and close the shoji 20 is attached to one indoor side of the vertical frame 23. Note that the heat insulating cover of the window frame 10 and the shoji 20 may be any material having low thermal conductivity, such as wood or hard rubber.

The most characteristic configuration in this embodiment will be described below. As shown in FIG.
In the lower frame main body 120, a screw for attaching and fixing the mounting piece 120A to the window stand (not shown) integrally with the heat insulating cover 32 is provided on the mounting piece 120A on the indoor side of the indoor member 121. A plurality of pilot holes 125 for the 124 (fixing member) are formed along the longitudinal direction, and the periphery of the pilot hole 125 is a mounting portion for the heat insulating cover 32. In addition, cutouts 126 are provided at a plurality of locations at regular intervals so as to exclude a mounting portion where each pilot hole 125 is formed. That is, in the mounting piece portion 120A, the mounting portion in which the pilot hole 125 is formed has the reinforcing portion 1 for reinforcing the heat insulating cover 32.
27, and only the reinforcing portion 127 is in contact with the heat insulating cover 32, so that the contact area between them is reduced. In addition, the heat insulation performance may be further improved by making the mounting piece portion 120A on the outdoor side the same configuration.

Here, the portion shown in FIG. 4 is a part of the lower frame 12 and is not shown, but both ends of the lower frame 12 are not cut-out portions 126 but reinforcing portions 12 which are mounting portions.
It is 7. Therefore, the entire end surface of the lower frame 12 including the reinforcing portion 127 abuts on the vertical frame 13, and the lower frame 12 is joined to the vertical frame 13 in a vertically winning state. In the lower frame body 120 of the lower frame 12, both end portions of the mounting piece 120A may be cutouts 126.

On the other hand, returning to FIGS. 1 and 2, in the vertical frame 13, the notch 1
36 are provided at a plurality of locations along the longitudinal direction. The mounting portion, which is a remaining portion where the notch portion 136 is not provided, is a reinforcing portion 1 for reinforcing the heat insulating cover 33.
37, and only the reinforcing portion 137 comes into contact with the heat-insulating cover 33, so that the mutual contact area is reduced.

However, at this time, the intervals and lengths of the notches 136 in the vertical frame 13 are not the same. That is, the notch 136 of the vertical frame 13 is the reinforcing portion 1 that is left almost at the center in the vertical direction.
The spacing and length are determined so that 37A is longer than the other reinforcing portions 137 and the strength of the central portion of the vertical frame 13 is greater. A receiving member 138 (frame attachment member) to which the above-described cam latch handle is locked is fixed to the center reinforcing portion 137A by screws 139 so as to sandwich the heat insulating cover 33 from the indoor side. By attaching the receiving member 138 to the stronger reinforcing portion 137A, even if the cam latch handle is locked to the receiving member 138, the vertical frame 13 does not bend. Further, both ends of the vertical frame 13 may be cutout portions 136 or reinforcing portions 137.

In this embodiment, the heat insulating covers 31 and 3 are previously attached to the frame main bodies 110, 120 and 130.
2 and 33 are engaged or partially screwed (the lower frame 12 is screwed to the mounting piece 120A on the indoor side) to form the frames 11, 1
2 and 13 are formed, and these are framed four times to assemble the window frame 10. On the other hand, the upper frame body 210 and the lower frame body 220
And the vertical frame 23 formed by screwing the heat-insulating cover 43 to the vertical frame main body 230, and then assembling the frame around the frame, incorporating the glass surface material 24 into the frame, further setting the upper frame main body 210 and the lower frame main body. The heat insulating covers 41 and 42 are engaged with the respective 220, and the shoji 20 is assembled. Then, at a construction site or the like, after disposing the window frame 10 in the opening of the building, the shoji screen 20 is incorporated into the window frame 10 via the hinge 2. At this time, when the window frame 10 is fixed to the opening, especially in the lower frame 12, each heat insulating cover 3
2 is also permanently fixed to the mounting piece 120A (reinforcing section 127) on the indoor side, and at the same time, this mounting piece 120A is fixed to the window stand.

According to such an embodiment, the following effects can be obtained. 1) In the lower frame 12 and the vertical frame 13 which are the heat insulating frames of the window frame 10, the cutouts 126 and 136 are formed in the heat insulating cover mounting pieces 120A and 130A of the frame main bodies 120 and 130, so that the heat insulating property is obtained. The contact area between the covers 32, 33 and the mounting pieces 120A, 130A (reinforcement sections 127, 137), that is, the frame main bodies 120, 130 can be reduced, and accordingly, heat conduction can be reduced and the occurrence of dew condensation can be suppressed.

2) Remaining portions of the mounting pieces 120A and 130A other than the cutouts 126 and 136 are reinforcing portions 127 and 137.
Since the heat insulating covers 32 and 33 can be reinforced by the reinforcing portions 127 and 137, the heat insulating covers 32 and 3 can be reinforced.
3 can be prevented, and the strength can be secured.

3) In particular, in the lower frame 12, since the frame main body 120 is a heat-insulated member including the heat insulating member 123,
The heat conduction inside and outside the room can be reduced, and the heat insulation performance and the dew-proof performance can be improved. In addition, since the mounting piece 120A is formed on the indoor member 121 made of a heat-insulating profile, heat transmitted from the outside to the mounting piece 120A can be reduced, and the heat insulating cover 32 that contacts the reinforcing portion 127 of the mounting piece 120A. Heat conduction to the body can be reduced. For this reason, the dew-proof performance in the heat insulating cover 32 can be further improved.

4) In the lower frame 12, the notch 1
Since 26 is formed excluding the end of the mounting piece 120A, even if the end of the lower frame 12 is joined to the vertical frame 13 by abutment, there is no fear that a gap is generated at this joint.
Good sealing performance and the like at the joint surface can be maintained. In the mounting piece 130A of the vertical frame 13, a notch 136 is formed at an end thereof.
A is formed, but the vertical frame 13 is composed of the upper frame 11 and the lower frame 12.
Are on the side where the upper frame 11 and the lower frame 12 are present on the indoor side of the notch 136A.
The sealing performance at the end of the mounting piece 130A can be favorably maintained.

5) Since the notches 126 in the lower frame 12 are formed at regular intervals along the longitudinal direction of the lower frame 12, reinforcing portions 127 for reinforcing the heat insulating cover 32 should also be provided at regular intervals. This can effectively prevent the heat-insulating cover 32 from flexing and the like, and can prevent the cooling heat from being concentrated on the specific reinforcing portion 127, thereby improving the dew-proofing performance and the heat-insulating performance.

6) Since each notch 126 of the lower frame 12 is formed except for a portion where the lower hole 125 for the screw 124 for fixing the heat insulating cover 32 is formed, a bracket or the like is separately used. At least, the heat insulating cover 32 is attached to the mounting piece 12.
0A can be reliably fixed, the fixing structure can be simplified, and the assembling workability can be improved.

7) In the vertical frame 13, the notch 136 is
Since the receiving portion 138 for the cam latch handle is formed so as to exclude a portion to which the receiving portion 138 is attached, such a receiving portion 138 can be directly attached to the attaching piece portion 130A, so that the attaching structure can be simplified and the assembly workability can be improved. Can also be improved.

8) At this time, since the attachment piece 130A to which the receiving member 138 is attached, that is, the reinforcing portion 137A is provided longer than the other reinforcing portions 137, the strength of the reinforcing portion 137A can be increased. Even when the cam latch handle is locked to the receiving member 138, the vertical frame 13 can be prevented from bending.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the window frame 10
Although the cutouts 126 and 136 are provided only in the heat insulating cover mounting pieces 120A and 130A of the lower frame 12 and the vertical frame 13 constituting the same, a plurality of similar cutouts are provided in the mounting piece 110A of the upper frame 11 as well. It may be provided at a location to reduce the contact area with the heat insulating cover 31. However, since the upper frame 11 is not required to have as high a dew-proof performance as the lower frame 12 and the vertical frame 13, it is possible to sufficiently prevent dew condensation by merely covering the mounting piece 110 </ b> A with the heat insulating cover 31 without providing a cutout. . In such an upper frame 11, the cost can be reduced as much as the notch is not provided by machining or the like.

In the above-described embodiment, only the lower frame 12 is a heat-insulated member including the heat insulating member 123, but the upper frame 11 and the vertical frame 13 may be heat-insulated members. However, by providing only the lower frame 12, which requires the highest dew-proof performance, with a heat-insulating profile, there is an advantage that the cost of the entire window frame 10 can be prevented from significantly increasing while the dew-proof performance can be reliably improved. is there.

Of course, all the frames 11, 12, and 13 may be formed of a normal extruded metal material such as aluminum, or the present invention may be applied to the case where the cutout 126 is provided only in the lower frame 12. include. That is, which frame is to be formed with the cutout portion and which heat insulating material is to be applied may be arbitrarily determined in consideration of the required dew-proofing performance and cost.

The present invention can be applied to the vertical sliding window 1 as described in the above embodiment, as well as the horizontal sliding window,
It can be applied to any sash, such as a casement window, bay window, sliding window, or entrance door.

FIGS. 5 and 6 show examples in which the present invention is applied to a vertical frame 13 of a window frame constituting a sliding window. The vertical frame body 130 of the vertical frame 13 also has a heat insulating cover 33 on the indoor side.
Is provided with a heat insulating cover mounting piece 130A for mounting. The mounting piece 130A is provided with a plurality of holes 135 for screws 134 for fixing the mounting piece 130A to the vertical frame 3 integrally with the heat insulating cover 33, and each of the holes 135 is provided. The cutout portion 136 is provided so as to remove the cut portion. The portion where the pilot hole 135 is formed, that is, the remaining portion where the notch portion 136 is not provided is a reinforcing portion 137 for reinforcing the heat insulating cover 33, and only the reinforcing portion 137 is the heat insulating cover 33.
By contacting with, the contact area of each other is reduced. Even in such a sliding window, the notch 136 provided in the vertical frame 13 can improve the dew-proofing performance of the vertical frame 13 and can reliably maintain its strength, thereby achieving the object of the present invention. As described above, the notch may be provided in the lower frame or the upper frame of the sliding window.
