Description of the Related Art Generally, a sliding sash provided on an outer wall of a building is known in which a four-sided frame is provided with a sliding door so as to be freely opened and closed. In this type, a vertical frame of a four-sided frame, an upper frame, a lower frame, and the like are configured by an aluminum outdoor frame member and an aluminum indoor frame member disposed inside the room,
The outdoor frame member and the indoor frame member are joined by a bridge material made of a low heat conductive material. This bridge material suppresses heat conduction between the outside and the room, and is caulked to each frame member, and this caulking presses a pair of rollers (“caulking tool”) from both sides against the bridge material caulking portion, This is performed by deforming the caulking piece from both sides.

[0003]

However, according to the conventional structure, it is impossible to integrally form the protrusion on the bridge material caulking portion for pressing the roller ("caulking tool").

For example, in a sliding sash or the like in which a sliding door is provided so as to be able to slide freely on a four-sided frame, an inner sliding door is provided near a bridging member on the side of the sliding door of the outdoor side frame member and the indoor side frame member in the vertical frame of the four-sided frame. In some cases, it is convenient to provide a protruding portion to be swallowed by the frame. In such a case, if it is not possible to integrally form the protrusion near the crimping head of the bridge material in relation to pressing the roller, the protrusion must be shifted from the rotational locus of the roller.
There is a problem of being restricted by design.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to form an aluminum mold having a heat insulating structure in which a protrusion can be integrally provided near a bridge material caulking head of each frame member. To provide lumber and sliding sashes.

When the inner sash 13 is moved to the right end in the figure and the inner sash 13 is completely closed, the airtight member 41 attached to the vertical frame 29 of the inner sash 13 is moved from the vertical frame 9 side of the four-sided frame 1. The airtightness is improved by closely adhering to the side surface of the protruding portion 43 made of aluminum.

As shown in FIG. 3, the projecting portion 43 is integrally provided on a surface (caulking head) 45b of the indoor side frame member 9b facing the inner sash 13 and the projecting portion 43 is provided.
Is, as shown in FIG. 4, a second roller 55 to be described later.
It is provided so as to extend substantially parallel to the insertion direction (the direction of the arrow C) of the (“receptor”).

The surface 45b provided with the protrusion 43 and the surface (caulking head) 45a of the outdoor frame member 9a facing the inner sash 13 are both formed flat.

FIG. 4 shows a structure of caulking a bridge member 21 for connecting the outdoor frame member 9a and the indoor frame member 9b. As shown in FIG. 4, the outdoor frame member 9a
A caulking hole 51 is formed in each of the portions to be joined to the indoor side frame member 9b, and an elongated bridge material 21 made of a low heat conductive material is inserted into the caulking hole 51 along a direction orthogonal to the paper surface. When the bridge member 21 is swaged, the first roller 53 is pressed in the direction of arrow B.
("Caulking device"), insert the second roller 55 ("Receiving device") from the direction of arrow C, and rotate each roller 53, 55 while applying pressure to the caulking portion with each roller 53, 55. By rolling around the axis L in the longitudinal direction of the frame member, two caulking pieces 57 located on the side opposite to the bridge material caulking portion 45 are pressed against the bridge material 21 side.

In this embodiment, the bridge material caulking heads 45a and 45b on the side where the protruding portion 43 is present are formed without crimping, that is, formed in advance in a flat shape, and the bridge material caulking heads 45a and 45b on the side opposite to the bridge material caulking heads 45a and 45b. Two caulking pieces 57 are provided on the portion, and the two caulking pieces 57 are caulked by a roller, so that each frame member has a bridge material 2.
1 is joined, so that the caulking operation is facilitated even if the protrusion 43 is present.

As shown in FIG. 4, there are no obstacles in the direction in which the first roller 53 enters, but there are obstacles formed by the protrusions 43 in the direction in which the second roller 55 enters.

In this embodiment, the second roller 55 is swaged with the bridge member caulking heads 45a and 45b while avoiding the protrusion 43.
The second roller 55 has a concave groove 55a capable of swallowing the protrusion 43 so that the second roller 55 can be brought into contact with the second roller 55b.
Are formed. In order to caulk the bridge member 21 to each frame member by deforming the caulking piece 57 on the opposite side to the protruding portion 43 by entering a receiving member (for example, a roller) while avoiding the protruding portion 43, the roller In addition to the provision of the concave groove 55a, it is also possible to divide the rollers into two, for example, so that each roller enters while avoiding the protrusion 43.

As described above, in the present embodiment, even if the above-mentioned protrusion 43 exists on the bridge material caulking heads 45a and 45b, the bridge material 21 is framed by using the second roller 55, for example. It can be easily crimped to the member.

Assuming that the second roller 55 has no means such as a concave groove, the protrusion 43 cannot be provided on the bridge material caulking head 45b as in the related art because the roller enters. For example, as shown in FIG. 4, the projection 43 must be moved to, for example, a position D indicated by a dotted line.

The inner sash 13 has a vertical frame 29 composed of an outdoor member 29a and an indoor member 29b, and the members are connected by a bridge member 31. Therefore, when there is a temperature difference between the indoor and the outdoor, the inner and outer members are connected. There is a difference in elongation between the members 29a and 29b, and the difference in elongation may cause the vertical frame 29 to bend. When the vertical frame 29 is curved and, for example, referring to FIG. 2, the protrusion 29 c of the vertical frame 29 contacts the protrusion 43, the opening and closing of the inner sash 13 cannot be performed smoothly. Therefore, in the window sash having the heat insulating structure, the protrusion 29c and the protrusion 4
Although the distance L between the three is designed to be large, as described above, if the protrusion 43 must be moved to, for example, a position D indicated by a dotted line as shown in FIG. L runs short.

In this embodiment, the protrusion 43 can be provided on the bridge material caulking head 45b, so that the distance L can be sufficiently set, and as a result, the shape of the indoor side frame member 9b of the vertical frame 9 can be improved. Each protrusion 29c, protrusion 43
Can be stored in a cohesive manner, and the degree of freedom can be given to the design of the window sash.

In this embodiment, the bridge material caulking portion 4
Since the portion corresponding to the protruding portion 43 can be freely formed in 5, an effect such that the degree of freedom in designing a window sash or the like can be greatly increased can be achieved.

Although the present invention has been described with reference to one embodiment, it is apparent that the present invention is not limited to the above embodiment.

For example, in the above embodiment, the present invention has been described in which the present invention is applied to the vertical frame, the upper frame, and the upper rail of the inner sash, but the present invention can be applied to any frame such as the lower frame. Further, the present invention can be applied to a lower rail or a vertical frame of a shoji. In addition, as long as a bridge member made of a low thermal conductive material for connecting the aluminum outdoor frame member and the aluminum indoor frame member is provided, all of the aluminum profiles having such a heat insulating structure can be used. It goes without saying that the invention is applicable.

[0028]

According to the first aspect of the present invention, the projecting portion can be arbitrarily formed with respect to the crimping head of the bridge member of the member, so that the degree of freedom in design of the aluminum material having the heat insulating structure is improved. Can be increased.

According to the second aspect of the present invention, since the protruding portion swallowed by the vertical frame of the sash can be arbitrarily formed on the crimping head of the bridge member of the frame member, the pulling sash having a heat insulating structure can be designed. The above degree of freedom can be increased.
