Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component of a heat insulating sash, and can be used for a frame or a frame constituting a window frame or a shoji.

[0002]

2. Description of the Related Art Conventionally, upper and lower left and right frame members or frames forming a window frame or a shoji are made of a metal indoor member such as aluminum disposed on the indoor side and a metal outdoor member disposed on the outdoor side. A heat insulating sash including a heat insulating member made of a synthetic resin such as urethane for connecting these indoor and outdoor members is known. In such a heat-insulating sash, for example, in a shoji screen, a lower door or a vertical frame is provided with a door puller and a digging pull. The heat insulating members of each frame are provided continuously over the entire length of the indoor and outdoor members in the longitudinal direction. For this reason,
Doors and engraving pullers do not interfere with the insulation
It is provided at a position shifted in the indoor and outdoor directions with respect to the heat insulating member. Furthermore, in the lower frame, the vertical width of the indoor / outdoor member is large due to the provision of the door roller, and in the vertical frame, the horizontal width is large due to the provision of the engraving puller. Is formed. In these lower frames and vertical frames, the indoor and outdoor members are securely connected to each other by two heat insulating members due to the large width of the indoor and outdoor members.

[0003]

However, in the lower frame and the vertical frame, since the door wheel, the digging pull and the heat insulating member are provided so as to be shifted in the indoor and outdoor directions, the indoor and outdoor members are compared with the ordinary sash. In this case, the width in the indoor and outdoor directions becomes large, and a large amount of material must be used to extrude these indoor and outdoor members, resulting in high cost. In addition, as much as a door wheel and an engraving puller are provided,
Since the width of the indoor and outdoor members in the vertical and horizontal directions is also large, it has been more difficult to reduce the cost.

[0004] Therefore, by setting the position of the door puller and the engraving puller in the indoor and outdoor directions to be the same as the position of the heat insulating member, the width of the indoor and outdoor members in the indoor and outdoor directions is reduced, and the door pulley and the engraving puller are also reduced. In order to avoid interference with the heat insulating member, the number of connecting portions between the indoor and outdoor members by the heat insulating member is reduced, so that the width dimension of the indoor and outdoor members in the vertical and horizontal directions is also reduced, thereby reducing costs. However, in such a case, the connection strength between the indoor and outdoor members is reduced, and the rigidity of each frame cannot be secured.

An object of the present invention is to secure rigidity and
It is an object of the present invention to provide a component of a heat insulating sash capable of reducing costs.

[0006]

The constituent members of the heat insulating sash according to the present invention reduce the number of connecting portions between the indoor and outdoor members by the heat insulating member, and connect the indoor and outdoor members using a reinforcing member. The object is achieved by devising the shape and arrangement position of the members.
Specifically, the constituent members of the heat insulating sash of the present invention are configured to include an indoor member disposed on the indoor side, an outdoor member disposed on the outdoor side, and a heat insulating member connecting the indoor member and the outdoor member. A plurality of piece-shaped reinforcing members having heat insulating properties are provided so as to straddle an indoor member and an outdoor member.

According to the present invention, even if the number of connecting portions between the indoor and outdoor members by the heat insulating member is reduced, the connection strength between the indoor and outdoor members is increased by providing the reinforcing member between the indoor and outdoor members. Thus, the rigidity of the components is ensured. At this time, by making the reinforcing member into a piece shape, it is possible to arrange the reinforcing member at a predetermined interval except for the position where the door puller or the engraving puller is provided. The hand and the reinforcing member are arranged in a straight line, increasing the vertical width and the horizontal width of the indoor and outdoor members, and increasing the indoor and outdoor width of the indoor and outdoor members. Therefore, it is not necessary to shift the door puller and the digging pull from the heat insulating member in the indoor and outdoor directions. For this reason, including that the number of connection points in the heat insulating member is reduced,
Since the indoor and outdoor members and the heat insulating member are formed with a small amount of material, the cost of the constituent members can be reduced. Here, the constituent members refer to, for example, a frame member, a frame, or the like that forms a window frame or a shoji of a heat insulating sash. Further, the piece-shaped reinforcing member has a length dimension smaller than the entire length of the indoor / outdoor member, and from the viewpoint of increasing the connection strength of the indoor / outdoor member, a heat insulating member for connecting the indoor / outdoor member. Means something different.

The constituent member of the heat insulating sash according to the present invention has a protruding side portion which is continuous with the longitudinal direction of the indoor member and the outdoor member and protrudes in a direction approaching to each other on the facing surface of the indoor member and the outdoor member. Preferably, the reinforcing member is provided so as to straddle between the protruding portions, and the reinforcing member is provided with engaging means for engaging with the protruding portions to prevent the reinforcing member from being detached from the indoor member and the outdoor member. . In such a case, for example, the reinforcing member can be easily and reliably attached by being fitted between the protruding sides.

Further, the constituent members of the heat insulating sash of the present invention are used for fixing the positions of the reinforcing members in the longitudinal direction of the reinforcing members at positions corresponding to both ends of the reinforcing members in the longitudinal direction of the respective projecting sides. It is desirable to provide fixing means (to prevent displacement). Although it is possible to fix the reinforcing member only by the frictional force between the reinforcing member and each protruding edge portion, the provision of the fixing means more reliably prevents the displacement of the reinforcing member in the longitudinal direction of the indoor and outdoor members. It becomes possible.

The fixing means may be a sponge which is in contact with at least one of the indoor member and the outdoor member to fix the position of each of the protruding portions of the reinforcing member in the longitudinal direction by the frictional force. May be provided.

According to the present embodiment, the following effects can be obtained. That is, the lower frame 42 and the vertical frame 43B
In this case, the indoor and outdoor members 46 to 49 are
Since they are connected not only by OC and 50D but also by the reinforcing member 60, the connection strength of the indoor and outdoor members 46 to 49 can be increased, and the rigidity of each of the frames 42 and 43B can be secured.

Further, since the lower frame 42 and the vertical frame 43B are connected by one heat insulating member 50C, 50D, the heat insulating member 5 is compared with the conventional frame which is connected by two heat insulating members.
0 can be reduced, and the cost of each frame 42, 43B can be reduced.

Since the engraving puller 51 and the door roller 52 are arranged on the same straight line as the reinforcing member 60, the lower frame 4
2 and the width of the vertical frame 43B in the horizontal direction (vertical direction in FIG. 1) can be reduced, and the width of the frames 42 and 43B in the indoor and outdoor directions can also be reduced. It is possible to reduce the amount of the material when the members 46 to 49 are extruded, and the cost of the frames 42 and 43B can be reduced from this point as well.

Further, since the lower frame 42 and the vertical frame 43B are connected by a single heat insulating member 50C, 50D, the urethane resin needs to be injected into each frame 42, 43B only once. 43B can be greatly reduced in assembling time.

At the time of the assembling work, the reinforcing member 60
Is easily provided between the protruding portions 70 by utilizing the elastic force of the vertical portion 64, so that the arranging operation of the reinforcing member 60 can be performed easily and quickly, and the assembling operation can be further easily performed.

With the cost reduction of the frames 42 and 43B and the improvement of workability and productivity, the entire sliding window 10 can be provided at a low cost.

Further, since the reinforcing member 60 is a short piece member, by changing the number of the reinforcing members 60 to be arranged, the reinforcing members 60 can be used for other lower frames and vertical frames having different length dimensions and required rigidity. And can be excellent in versatility.

Further, since the reinforcing member 60 is provided with the engaging portion 66, the reinforcing member 60 is connected to the indoor and outdoor members 46 to 49.
It can be easily and reliably mounted simply by fitting it in the middle.

Since the caulking portion 72 is provided on each of the protruding portions 70 of the indoor and outdoor members 46 to 49, the reinforcing member 60 is compared with a case where the reinforcing member 60 is simply fixed by the frictional force with the protruding portion 70. In addition, the displacement of the indoor and outdoor members 46 to 49 in the longitudinal direction can be more reliably prevented.

Further, since the width of the lower frame 42 and the vertical frame 43B is reduced, the glass opening for the entire shoji 40 is increased, so that a large amount of light can be collected and the design can be improved.

It should be noted that the present invention is not limited to the above-described embodiment, but includes the following modifications and the like. For example, the reinforcing member is not limited to the above-described embodiment, and a reinforcing member 100 as shown in FIG. 5 may be used.

The reinforcing member 100 is made of a synthetic resin such as polyamide, and has protruding sides 101 formed at both end edges of the indoor and outdoor members 48 and 49, and inside the protruding sides 101 along the protruding side 101. Engaging portion 1 formed and bulged outward
02A having an engagement side 102A. And
Pushing and engaging the reinforcing member 100 until the engaging portion 102A is located on the outer peripheral side of the protruding portion 70 of the indoor / outdoor member 48, 49, and sandwiching the protruding portion 70 between the protruding edge 101 and the engaging side 102. As a result, the reinforcing member 100 is
It does not come off from 49.

Further, the reinforcing member 100 includes a heat insulating member 5.
A sponge 103 made of urethane rubber or the like abutting across the indoor and outdoor members 48 and 49 connected at 0 is attached. The sponge 103 is used for the indoor and outdoor members 48,
The longitudinal displacement of the indoor and outdoor members 48 and 49 of the reinforcing member 100 is prevented by the frictional force caused by the contact with the sponge 49, and the sponge 103 forms a fixing unit. If the reinforcing member 100 having such a sponge 103 is used, it is not necessary to caulk the protruding side portion 70 as in the above-described embodiment, so that the mounting work of the reinforcing member 100 can be reduced.

It is to be noted that, for example, the reinforcing member 100 is
For example, as shown in FIG. 6, a sponge 103 is provided on the surface of the reinforcing member 100 opposite to the surface on which the protruding side 101, the engaging side 102, and the like are formed.
The sponge 103 may be brought into contact with the indoor / outdoor members 48 and 49 located above the 00. Further, the sponge 103 may be brought into contact with only one side of the indoor and outdoor members 48 and 49. In short, when the sponge 103 is used as the fixing means, the sponge 103 is reinforced by the frictional force between the indoor and outdoor members 48 and 49. What is necessary is just to be able to prevent the displacement of the member 100.

The means for fixing the reinforcing member 100 is not limited to the sponge 103 made of urethane rubber, but has a heat insulating property, a relatively large frictional force, and the indoor and outdoor members 48, 49.
Any material that can prevent the displacement of the reinforcing member 100 by abutting the contact member may be used.

Further, in the above embodiment, the reinforcing member 6
Although the shape of 0 is a U-shaped cross section, the overall shape of the reinforcing member may be arbitrarily determined in consideration of the shape of the protruding portions formed on the indoor and outdoor members. Also, the reinforcing member 6
Although the whole of 0 was made of synthetic resin, for example, a metal plate was buried inside by insert molding to improve the strength, or such a metal plate was exposed,
You may make it arrange | position between both indoor and outdoor members by covering the both ends with a synthetic resin. In the reinforcing member 60, the heat insulating property is ensured by using a synthetic resin as the material. However, the material is not limited to this. For example, the heat insulating property may be ensured by using a wooden material. In short, the reinforcing member may be any member that does not conduct heat between the indoor and outdoor members, and its shape, configuration, material, and the like may be appropriately determined in implementation.

Further, the interval between the plurality of such reinforcing members is not limited to 500 mm as in the above embodiment, but may be appropriately determined in consideration of the size of the heat insulating sash. May be.

In the above embodiment, the indoor and outdoor members 4
Although the caulking portions 72 of 6 to 49 are provided before the reinforcing member 60 is arranged, the caulking portion 72 may be provided when the procedure is reversed, that is, after the reinforcing member 60 is arranged.

In the above embodiment, the reinforcing member 6
0 is used for the lower frame 42 and the vertical frame 43B, but the present invention is not limited to this. A reinforcing member may be used for the frame, and the rigidity may be improved or the cost may be reduced by using the reinforcing member for each frame member constituting the window frame.

Furthermore, in the above-described embodiment, a single heat insulating member 50C, 50D is provided between the indoor and outdoor members 46 to 49 constituting the lower frame 42 and the vertical frame 43B. The indoor and outdoor members may be connected by a plurality of heat insulating members

At this time, the heat insulating member is not limited to a member into which a urethane resin is injected, but is a plate made of a synthetic resin, and is disposed between the indoor and outdoor members and caulked. It may connect indoor and outdoor members.

In the above embodiment, the reinforcing member 60
Although the engaging means including the engaging portion 66 is provided, for example, the reinforcing member is provided across the indoor and outdoor members, and the reinforcing member is separated from the indoor and outdoor members by a frictional force or the like at a contact portion with each indoor and outdoor member. If it does not come off easily, the engaging portion 66
It is not always necessary to provide such an engagement means. Similarly,
If the displacement of the reinforcing member is prevented by a frictional force or the like at a contact portion between the reinforcing member and each of the indoor and outdoor members, the fixing means may not be provided. In short, the reinforcing member may be provided with both the engaging means and the fixing means, may be provided with at least one, or may not be provided, and these may be appropriately set in practice.

Furthermore, although the sliding window 10 has been described in the above embodiment, the present invention is not limited to this.
It can be applied to various insulating sashes.

[0048]

As described above, according to the present invention, even if the number of connecting points of the heat insulating member between the indoor member and the outdoor member is reduced, the indoor and outdoor members are also connected by the reinforcing member. The rigidity of the constituent members can be ensured by increasing the connection strength of the outer members, and since the reinforcing member is in the form of a piece, interference with various members provided between the indoor and outdoor members can be avoided so that those indoor members can be prevented. Since the width of the outer member can be reduced and the number of connection points at the heat insulating member can be reduced, there is an effect that the cost can be reduced by reducing the materials of the indoor and outdoor members and the heat insulating member.
