Description

[Detailed description of the invention] When manufacturing a heat insulating sash bar, the present invention uses a sheet-like heat insulating closing member placed between one side member and the other side member to form a groove between both side members. This relates to a device for fixing the

When manufacturing a heat insulating sash bar, as shown in FIG. A groove f is formed by the side members a and c and the sheet material e, and this groove f is filled with a heat insulating material.

Here, since the sheet material e is injected and filled with a heat insulating material, it is necessary to fix both ends of the sheet material e to both side members a and c. Curve e′ downward, and both side members a,
Adhesive tape g is pasted across end faces a' and c' of c to fix it.

However, fixing with the adhesive tape g is insufficient to fix the sheet material e, and as shown by the phantom lines in FIG. As a result, the heat insulating material could not be properly injected and filled into the groove f formed by the side members a and c and the sheet material e, resulting in a poor appearance and the connection strength of the heat insulating material between the both side members a and c was reduced. It ends up.

In addition, the adhesive tape g closes the openings at both ends of the groove f to prevent the injected insulation material from spilling out, but if the adhesive tape g alone is used, it easily peels off, causing an accident in which the injected insulation material spills out. It tends to occur depending on the situation.

The present invention was developed in view of the above circumstances, and its purpose is to firmly fix both ends of a heat insulating closure member placed between both side members to both side members, and to prevent the injection-filled insulation material from spilling out. It is an object of the present invention to provide a device for fixing both ends of a heat insulating cold-closing member placed between both side members, which can reliably prevent this.

Embodiments of the present invention will be described below with reference to FIG. 4 and subsequent figures.

FIG. 4 is an overall perspective view, in which one side member 10 and the other side member 20 are connected by a connecting wall 1, and protrusions 11 and 21 are opposed to each other on both side members 10 and 20 in the longitudinal direction. , and the protrusions 11, 2
On the side opposite to the connecting wall 1, locking pieces 12 and 22 bent into hook shapes are formed facing each other in the longitudinal direction.

2 is a sheet-like heat insulating closure member (hereinafter referred to as a sheet material) placed between the opposing protrusions 11 and 21;
Both side members 10 and 2 are closed by closing the gap 3 between them.
0 to form a groove portion 4.

In FIG. 4, 30, 30 are a pair of caps, which connect both ends of the sheet material 2 to both side members 10, 2.
Fix it to both ends of 0.

The cap 30 is connected to the vertical wall 3 as shown in FIG.
1, a pair of locking claws 32, 32 are integrally formed, and a horizontal wall 33 is integrally formed between the pair of locking claws 32, 32, and the width _H1 of the vertical wall 31 is the width H1 between the both side members 10, 20. is approximately the same as the distance L ₁ , and the height H ₂ is the distance L 2 between the protrusions 11, 21 and the locking pieces 12, _22.
is substantially the same as that, and its upper end surface 31a
The portion facing between the opposing locking pieces 12 and 22 forms a slope 34.

The pair of locking claws 32, 32 are connected to the protrusions 11, 21.
and the locking pieces 12, 22 at a height _H3 that fits between the locking pieces 12 and 22,
and the outer surfaces 32a, 3 of the pair of locking claws 32, 32.
The distance H ₄ between 2a is the inner surface 1 of both side members 10 and 20.
0a, _20a , and the distance _H5 between the inner surfaces 32b, 32b is the same as the width of the slope 34. The strips 11, 21 and the locking piece 12,
22.

Note that the distal ends of the pair of locking claws 32, 32 are chamfered to have a tapered shape.

The horizontal wall 33 is shorter than the locking claw 32, its lower surface 33a is the same as the lower surface 32c of the locking claw 32, and its upper surface 33b is the same as the upper surface 32 of the locking claw 32.
It is lower than d by H ₆ .

When the cap 30 is fitted between the both side members 10 and 20 with both ends of the sheet material 2 curved downward, the pair of locking claws 32 and 32 are inserted into the inner surfaces of the both side members as shown in FIG. 10a, 20a, each protrusion 11, 21, and each locking piece 12, 22, the cap 30 is firmly fixed to both side members 10, 20 by abutting fit thereon.

On the other hand, the lower surface 33a of the horizontal wall 33 presses the sheet material 2 onto the pair of protrusions 11, 21, and the inner surface 31b of the vertical wall 31 below the horizontal wall lower surface 33a presses the sheet material 2 onto the end surface 11a of each of the protrusions 11, 21. 21a to firmly fix both ends of the sheet material 2 to both side members 10 and 20.

In other words, the lower surface 33a of the side wall extends from the sheet material 2 to the protrusion 1.
1 and 21, and the inner surface 31b holds the sheet material 2 against the protruding end surfaces 11a and 21a.
It is a fixed wall part that is bent at right angles to and crimped.

Further, the remaining inner surface 31c of the vertical wall 31 comes into contact with the end surfaces 10b and 20b of both side members to prevent the heat insulating material injected into the groove 4 from spilling out.

In other words, the inner surface 31c serves as a wall to prevent the heat insulating material from falling out.

In this way, both ends of the sheet material 2 can be firmly fixed to the side members 10, 20 by the pair of caps 30, 30, so the caps 30, 30 can be fitted while the sheet material 2 is stretched and tensioned. The sheet material 2 does not flop around, become wavy, or float up on both ends, unlike conventional methods, and the heat insulating material can be injected and filled into the groove 4 correctly, improving the appearance. , the strength of the connection between the side members 10 and 20 by the heat insulating material can be increased.

Further, spilling of the injected and filled insulation material on the inner surface 31c of the vertical wall of the cap 30 can be reliably prevented.

Further, the expansion of the sheet material 2 due to preheating of both side members before injection of the heat insulating material and heat generated during hardening of the heat insulating material can be absorbed by tensioning the sheet material 2 before fitting the cap.

In addition, since the vertical wall 31 is formed with a slope 34, a plurality of both side members are arranged continuously in a straight line,
When moving the insulating material injection nozzle to continuously inject the insulating material into each groove, the insulating material is smoothly injected into the groove 4 along the slope 34 when the insulating material injection nozzle moves between adjacent side members. It does not spill outside.

The present invention is as described above, and both ends of the heat insulating closure member 2 can be firmly fixed to prevent the heat insulating closure member 2 from becoming loose, wavy, or floating.
The heat insulating material can be properly injected and filled to improve the appearance, and the strength of the connection between the side members 10 and 20 by the heat insulating material can be increased.

Further, it is possible to reliably prevent the heat insulating material injected into the groove portion 4 from spilling out.
