DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Since an aluminum profile, which is a main component of a sash, has a high thermal conductivity, it is combined with a resin material to form a heat insulating sash.

[0002] The present invention relates to an apparatus for joining an aluminum profile and a resin profile in a sash component, which is used to obtain such a heat insulating sash.

[0003]

2. Description of the Related Art A resin injection type and a hard resin material having an I-shaped cross section, in which a resin liquid is filled in a groove provided between indoor and outdoor members and cured, and a bottom wall piece of the groove is scraped off, There is a caulking type which is interposed between indoor and outdoor members made of an aluminum shape member and crushes and engages a locking piece having a claw-shaped cross section provided on a facing surface side of the member.

[0004]

The resin injection type in the conventional example is not only complicated in shaving work, but also requires waste material treatment, and the shaved surface lacks a protective film due to surface treatment. There is a disadvantage that corrosion is easily caused.

Also, the caulking type has a drawback that the aluminum member is caulked and fixed to the hard resin material, so that there is a tendency to play back due to processing accuracy.

The present invention has been made with the object of providing a joining apparatus having such a structure without such disadvantages.

[0007]

Means for Solving the Problems A pair of engaging grooves formed of pieces facing the opposing surface are provided on the surface of the aluminum member facing the resin member, and are slidably fitted into the engaging grooves. A pair of press-fitting pieces opposing each other through the engaging pieces are provided by providing an engaging piece that is in pressure contact with the piece on the resin shape member and inclining in a direction of gradually separating from each other as far as the tip. The press-fitting piece is provided at the tip thereof with a locking piece for locking to a receiving piece provided on the aluminum shape material.

A receiving portion 7A for locking the locking portion 12A is provided on the aluminum profile 2A portion via A and 5A.

When the engaging sections 9A, 9A are relatively slid into the engaging grooves 5A, 5A of the outdoor side aluminum section 2A, the resin section 3A and the aluminum section 2A are slid. The members 2A are slid onto each other, and in this state, the press-fitting piece 1
When the tilt angles are displaced in the horizontal direction by rotating the 1A, 11A about the hinges 10A, 10A, the press-fitting piece 1
1A and 11A are gaps 1 formed by indoor and outdoor profiles 2A and 3A.
3A, 13A are forcibly press-fitted, and the locking piece 12A of the press-fitting piece 13A is locked on the receiving piece 7A. It is pressed against the piece 2Aa of the section 2A and the sections 2A and 3A are temporarily joined. (Because the joining at the stage before assembling and constructing the sash frame assembly or the frame assembly, the sash components can be tapped. It does not necessarily have to be a fixed joining state as in the case of obtaining the framework by tightening with screws).

When an external force is applied in the compressing direction, the press-fitting piece 11A functions as anti-compression, and when an external force is applied in the pulling direction, the contact relationship between the piece 2Aa and the engaging piece 9A is determined to be tensile-resistant.
