Description

[Detailed description of the invention] This invention relates to a heat insulating device that connects the inner and outer frames of a double sash in a heat-insulating manner. To enable assembly and installation of double sashes without any trouble even if errors or assembly errors occur.

The present invention will be explained below with reference to a preferred embodiment shown in the drawings. In Fig. 1, 1 is an outer frame of a double sash, 2 is an inner frame, and these inner and outer frames 1 and 2 have inner and outer auxiliary frames 3 and 4. They are placed opposite each other. In the case of this example, as shown in FIG. The elongated hole in the direction allows fine vertical adjustment of the auxiliary frames 3 and 4 during screwing. In addition, regarding this fine adjustment, it is sufficient that either one of the long holes 6 and 7 is formed. On the other hand, it is screwed on so that it can be finely adjusted up and down. The auxiliary frames 3 and 4 may be provided by integrally molding one side with the frame, or by welding or riveting, if necessary, and may be finely adjusted as described above. Even if there is no configuration, the purpose of the present invention can be fully achieved as described later. In particular, when the outer auxiliary frame 3 is integrally molded with the outer frame 1 in advance, the screwing operation can be omitted and the sash assembly can be speeded up.

Locking portions 8 and 9 are formed on the outer auxiliary frame 3 and the inner auxiliary frame 4, respectively. In the case of this example, the parts 8 and 9 are composed of bent pieces. In addition to the bent pieces, the locking parts 8 and 9 may have any shape as long as they can be engaged with the heat insulating bonding material 11, which will be described later. Furthermore, locking protrusions 10 are integrally molded at appropriate locations on the outer auxiliary frame 3 to ensure engagement of the heat insulating bonding material 11.

The heat insulating bonding material 11 is made of hard synthetic resin, and has bulges formed at both ends 11a and 11b so as to be able to engage with the locking parts 8 and 9. Also, 12
is a heat insulating bead made of soft synthetic resin, which has appropriate elasticity considering the size of the double sash. In addition, when the heat insulation device of the present invention is applied to the left and right vertical frames (not shown) and is formed on the same plane as the upper and lower frames, the heat insulation bead 12 is made into an endless shape with an appropriate length. It is possible to avoid the generation of gaps at the sash corner portions of the bead, and therefore it is possible to achieve further heat-insulating, sound-proofing and air-tight effects.

Reference numeral 13 denotes a heat insulating material, which is disposed on the inner auxiliary frame 4 and acts as a heat insulator between the inner frame 2 and the inner frame 2. Therefore, the heat insulating bead 12 and the heat insulating material 13 can provide double heat insulation, improving efficiency.

Next, a preferred procedure for installing the heat insulating device of the present invention will be described. First, the outer frame 1 is fixed in a predetermined position, and then the inner frame 2 to which the inner auxiliary frame 4 is fixed is fixed. The outer auxiliary frame 3, in which the heat insulating binding material 11 is fitted and locked in the locking portion 8 in advance, is temporarily screwed onto the outer frame 1 with the screw 5, and the other end 11b of the binding material 11 is attached to the locking part 8 of the inner auxiliary frame 4. The inner and outer auxiliary frames 3 and 4 are temporarily fixed by engaging with the stop portion 9, and the heat insulating bead 12 is press-fitted between both the auxiliary frames 3 and 4. At the same time, the outer auxiliary frame 3 is fastened to the outer frame 1, and the fixation of the inner and outer auxiliary frames 3 and 4 is completed.

As explained above, the heat insulation device according to the present invention has the following features:
Inner and outer auxiliary frames each having a locking portion are provided opposite the inner and outer frames, and a heat insulating bonding material made of hard synthetic resin is engaged with the locking portion to temporarily fasten the two, and a Since the heat insulating bead is press-fitted between the inner and outer auxiliary frames, the installation accuracy of the inner and outer frames is not high due to manufacturing or assembly errors. Even if a positional shift occurs, such shift will be absorbed or corrected by the elastic deformation of the heat insulating bead as long as the heat insulating bonding material does not become disengaged, and the connection between both auxiliary frames will be sufficiently maintained. , heat insulation and soundproofing effects can be fully exhibited. The above-mentioned effects unique to the present invention can be even more pronounced if one or both of the inner and outer auxiliary frames are configured to be vertically adjustable with respect to the inner and outer frames. What you can do is what you get. Although the embodiment has been illustrated and described with respect to the lower frame portion of the double sash, it goes without saying that the present invention can also be applied to the inner and outer vertical frame portions.
