Description

  The present invention relates to a heat insulating frame member and joinery, and more particularly, to a heat insulating frame member in which metal members are connected to each other through a heat insulating member, and a joiner configured to include the heat insulating frame member.

Conventionally, it has a pair of metal members (aluminum profile) and a resin heat insulation member (heat insulation bridge) that connects them, and by engaging a part of the metal member with the heat insulation member The heat insulating shape material (heat insulating frame material) integrated is known, and is used for fittings such as sash windows (see, for example, Patent Document 1).
In the heat insulating shape described in Patent Document 1, a pair of receiving pieces and caulking pieces are formed at both ends of each of the metal one side member and the other side member, and heat insulation is performed between the receiving piece and the caulking piece. In a state where the member is positioned, the crimping roller is used to receive the crimping piece and deform toward the piece (caulking), thereby sandwiching the heat insulating member and integrating the one side member, the other side member, and the heat insulating member. It is a thing.

  However, in the conventional heat insulating shape as described in Patent Document 1, a mandrel that receives a reaction force by contacting the back side of the receiving piece so that the one side member and the other side member are not deformed when caulking. Needs to be installed between the one side member and the other side member, and there is a problem that the cross-sectional form of the heat insulating shape member is restricted. In addition, in the conventional heat insulating shape, the crimping piece is formed at both ends of the main body of the one side member or the other side member and is crimped from the outside, but the main body is cantilevered beyond the crimping piece position. In the case of a member having a cross-sectional shape extended in a shape, there is a possibility that the tip end side of the cantilever is inclined inward by caulking, and this also restricts the cross-sectional shape of the heat insulating shape. .

  An object of the present invention is to provide a heat insulating frame material and a fitting capable of increasing the degree of freedom of the cross-sectional shape while suppressing deformation due to caulking.

  The heat insulation frame material of this invention is a heat insulation frame material provided with the 1st and 2nd metal member, and the heat insulation member which connects these metal members, Comprising: Opposition of the said 1st and 2nd metal member A pair of caulking pieces and a receiving piece each projecting from one facing surface to the other facing surface are formed on the surface, and the end of the heat insulating member is positioned between the caulking pieces and the receiving piece. In this state, the end of the heat insulating member is clamped by deforming the caulking piece toward the receiving piece, and the caulking piece and the receiving piece are respectively caulked to positions facing each other with the heat insulating member interposed therebetween. A piece engaging protrusion and a receiving piece engaging protrusion are formed, and on the back side of the caulking piece engaging protrusion in the caulking piece, a pressing surface portion that is pressed for deformation is provided, and the caulking piece The tip side is continuous with the pressing surface. A front end surface portion extending toward the caulking piece engaging protrusion is provided, and on the end portion side of the heat insulating member, a contact surface portion that contacts the opposing surfaces of the first and second metal members, An engagement end formed by a first engaged surface portion engaged with the caulking piece engaging protrusion and a second engaged surface portion engaged with the receiving piece engaging protrusion is provided. An inclined surface portion that intersects the first engaged surface portion and extends in a direction away from the engagement end portion and that is inclined with respect to the caulking direction of the caulking piece, and deforming the caulking piece, The caulking piece engaging protrusion and the receiving piece engaging protrusion engage with the first engaged surface portion and the second engaged surface portion of the heat insulating member, respectively, and the front end surface portion of the caulking piece is the inclined surface portion. And the first and second metal members and the heat insulating member are joined. It is characterized in.

  According to the present invention, the caulking piece engaging protrusion and the receiving piece engaging protrusion are engaged with the first engaged surface portion and the second engaged surface portion of the heat insulating member by caulking the caulking piece, Occurs at the end (base end) on the facing surface side of the crimping piece by holding the engagement end part between the crimping piece and the receiving piece and bringing the tip surface part of the crimping piece into contact with the inclined surface part of the heat insulating member Stress to be suppressed. That is, by bringing the tip surface portion into contact with the inclined surface portion, a compressive force from the tip end of the caulking piece toward the base end acts, and the caulking piece engaging protrusion is pressed against the first engaged surface portion by this compressive force. Therefore, this pressing force is applied to the engaging force of the caulking piece engaging protrusion. As a result, even if the caulking piece is not greatly deformed with a high pressing force by the caulking device, the engagement force necessary to exert the predetermined connection strength can be obtained, so that the stress generated at the base end portion of the caulking piece is suppressed. The deformation of the first and second metal members can be suppressed, and a device for suppressing the deformation (a conventional mandrel or the like) or a form of the metal member (a caulking piece is provided at the end portion or made hollow) Etc.) can be made unnecessary. Accordingly, a metal member having an arbitrary cross-sectional shape can be used, and the degree of freedom of the heat insulating frame material can be increased, and the structure and work process of the caulking device can be simplified, and the manufacturing cost can be suppressed.

At this time, in the heat insulating frame material of the present invention, a concave portion that is recessed toward the proximal end side of the caulking piece between the distal end surface portion and the caulking piece engaging protrusion on the distal end side of the caulking piece. Is preferably formed.
According to such a configuration, the contact position between the tip surface portion and the inclined surface portion of the heat insulating member is formed by forming a recessed portion between the tip surface portion and the crimping piece engaging protrusion on the tip side of the crimping piece, The engagement position between the caulking piece engaging projection and the first engaged surface portion can be separated by the dimension of the recessed portion, and the tip surface portion can be reliably brought into contact with the inclined surface portion. Therefore, the effect of increasing the engagement force due to the compressive force of the distal end surface portion as described above can be reliably exhibited, and the stress generated at the proximal end portion of the crimping piece can be more reliably suppressed.

Furthermore, in the heat insulating frame material according to the present invention, the heat insulating member includes a second inclination that extends in a direction crossing the second engaged surface portion and away from the engagement end portion and is inclined with respect to the caulking direction. It is preferable that a surface portion is provided and the second inclined surface portion and the tip end portion of the receiving piece are configured to contact each other.
According to such a configuration, the tip end portion of the receiving piece is brought into contact with the second inclined surface portion formed on the heat insulating member, so that the tip surface portion of the crimping piece is brought into contact with the inclined surface portion of the heat insulating member. The action can be exerted also on the receiving piece, and the engaging force of the receiving piece engaging protrusion can be increased. Therefore, the stress generated at the base end portion of the receiving piece can be suppressed and deformation of the first and second metal members can be suppressed.

In the heat insulating frame material of the present invention, the heat insulating member includes a first intermediate surface portion that connects the inclined surface portions formed on both ends, a second intermediate surface portion that connects the second inclined surface portions, and the second intermediate surface portion. A hollow portion provided between the first and second intermediate surface portions, and in a state where the caulking piece is deformed, the pressing surface portion is provided at a position protruding from the first intermediate surface portion. Preferably it is.
According to such a configuration, by using a heat insulating member having a hollow portion, the cross-sectional area of the heat insulating member can be reduced while ensuring predetermined strength and rigidity, and the amount of raw materials used can be saved. Furthermore, since the pressing surface portion of the crimping piece is provided at a position protruding from the first intermediate surface portion, the crimping device does not come into contact with the first intermediate surface portion (heat insulating member), and when the crimping piece is crimped Damage to the heat insulating member can be prevented. In addition, by setting the protruding dimension of the pressing surface portion from the first intermediate surface portion as small as possible, it is possible to reduce the unevenness of the surface of the manufactured heat insulating frame material while preventing damage to the heat insulating member, and to improve the appearance design. Can be improved.

Thus, the first metal member 21, the second metal member 22 and the heat insulating member 23 are coupled to each other by the crimping piece 22B and the receiving piece 22C.

According to this embodiment, there are the following effects.
(1) That is, the stress which generate | occur | produces in the base end side connection part 216,226 of the crimping piece 21B, 22B because the front end surface parts 214,224 of the crimping piece 21B, 22B contact | abut to the 1st inclined surface part 234 of the heat insulation member 23. Can be suppressed. That is, the caulking piece engaging protrusions 211 and 221 are pressed against the first engaged surface portion 232 by the reaction force with which the front end surface portions 214 and 224 abut, and the engaging force is increased. It is not necessary to press 223 excessively, and the stress which generate | occur | produces in the base end side connection part 216,226 of caulking piece 21B, 22B and the 1st and 2nd metal members 21 and 22 whole can be suppressed. Therefore, the first and second metal members 21 and 22 do not have to have a highly rigid shape such as a hollow (hollow) shape, and members having an arbitrary cross-sectional shape can be used. The degree of freedom in design can be increased, and the structure and work process of the caulking device can be simplified, and the manufacturing cost can be suppressed.

(2) Since the recessed portions 215 and 225 are formed on the distal end sides of the crimping pieces 21B and 22B, the contact position between the distal end surface portions 214 and 224 and the first inclined surface portion 234 of the heat insulating member 23, and the crimping pieces The engagement positions of the engaging protrusions 211 and 221 and the first engaged surface portion 232 are separated from each other, and the front end surface portions 214 and 224 can be reliably brought into contact with the first inclined surface portion 234. Accordingly, the action of increasing the engagement force of the caulking piece engaging protrusions 211 and 221 due to the reaction force with which the front end surface portions 214 and 224 abut can be surely exerted, and the proximal end side connecting portions 216 and 226 of the caulking pieces 21B and 22B The generated stress can be more reliably suppressed.

(3) Further, on the receiving pieces 21C and 22C side, the second tip end surface portions 217 and 227 of the receiving pieces 21C and 22C are brought into contact with the second inclined surface portion 235 of the heat insulating member 23, so that they are the same as the caulking pieces 21B and 22B. This can also be exerted on the receiving pieces 21C and 22C, and the engaging force of the receiving piece engaging projections 212 and 222 can be increased. Therefore, it is possible to suppress the stress generated at the base end portions of the receiving pieces 21C and 22C and suppress the deformation of the first and second metal members 21 and 22.

(4) Further, since the pressing surface portions 213 and 223 of the deformed crimping pieces 21B and 22B are located so as to protrude from the first intermediate surface portion 236 of the heat insulating member 23 toward the caulking disc D, the caulking disc D is insulated from the heat insulating member 23. The heat insulation member 23 can be prevented from being damaged when the crimping pieces 21B and 22B are crimped. In addition, by setting the projecting dimension of the pressing surface portions 213 and 223 from the first intermediate surface portion 236 as small as possible, the unevenness of the surface of the manufactured heat insulating frame member 20 can be reduced while preventing the heat insulating member 23 from being damaged. And appearance design can be improved.

Hereinafter, with respect to the heat insulating frame member 20 of the above embodiment, an example in which the stress during caulking is calculated by numerical analysis will be described with reference to FIG.

The projecting dimension is 0.2 mm larger than that. In addition, as analysis conditions in each embodiment, the crimping pieces 21B and 22B are deformed until the first and second metal members 21 and 22 and the heat insulating member 23 have a predetermined connection strength, and a predetermined connection strength is obtained.

It was confirmed that it was smaller.

  From the analysis results in the first and second embodiments described above, the first metal member 21 and the crimping pieces 21B and 22B are brought into contact with the first inclined surface portion 234 of the heat insulating member 23 by contacting the tip surface portions 214 and 224 of the crimping pieces 21B and 22B. It was confirmed that the stress and deformation of the second metal member 22 were suppressed. Then, it can be confirmed that the protrusion size of the tip surface portions 214 and 224 has a great influence on the stress and deformation suppressing action, that is, the deformation can be effectively suppressed by bringing the tip surface portions 214 and 224 into stronger contact. It was.
