Description

The present disclosure relates to a lumber fixing structure and fittings.

Conventionally, in fittings such as sliding windows, sliding windows, and FIX windows, shoji screens are widely used in a frame composed of an upper frame, a lower frame, and left and right vertical frames. The design of these frames is enhanced by attaching a resin profile as a decorative material to the indoor side of a metal profile such as an aluminum alloy. In a frame provided with such a resin profile, the resin profile is attached to the metal profile with screws or the like to prevent the resin profile from slipping, but it takes time and effort to fasten the screws. .. In addition, since the resin profile shrinks due to the influence of temperature during processing and transportation, there is a risk that if the resin profile is fixed with screws, the resin profile shrinks, for example, a gap is formed between the profiles.

On the other hand, a notch is formed in the metal profile, a notch is formed at a position corresponding to the notch in the resin profile, and the notch is fitted into the notch and crimped to crimp the resin profile. There is known a fitting that employs a shape member fixing structure for fixing a metal shape member (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2017-133253

In conventional fittings, when performing maintenance such as replacing the resin profile, the metal profile is first crushed by caulking, so the crimped part is destroyed and the resin profile is removed. .. When fitting a new resin profile into the metal profile, the metal profile is crushed by the previous caulking fixing, so that a space for fitting the new resin profile cannot be secured. Therefore, fitting becomes difficult, and for example, it is necessary to process a portion of a new resin profile that interferes with the caulking fixing portion before performing the fitting work, which is a laborious work and reduces work efficiency. There was room for improvement.

The present disclosure provides a shape material fixing structure and fittings that can secure a space for fitting a resin shape material and can reduce the labor and time required for maintenance work.
