By the way, as the material of the above-mentioned heat insulating cover, a resin such as black, bronze or white is used according to the color of the metal part of the window frame or the shoji. For this reason, in order to improve the design of the sash as a whole, the screen frame is also unified with the same color, mainly in the screen frame. Then, the window frame or the heat insulating cover of the shoji and the frame of the screen door are viewed from the indoor side.
In this case, since the frame of the screen door is made of metal, it is necessary to paint the frame to unify the colors. However, in the part of the sash window that can be viewed from the inside of the room, the resin insulation cover that makes use of the color of the material itself and the screen frame of metal door painted, the surface when viewed from the indoor side There is a great sense of discomfort in terms of texture, such as a slight difference in gloss and the like, and a different feel when touched.

Some recent heat-insulating covers have a wood grain pattern formed on the surface by mixing wood powder in a synthetic resin. In order to match the shade of the screen with such a heat-insulating cover, it is difficult to apply woodgrain to the screen, so a resin sheet printed with woodgrain is attached. However, even in this case, on the one hand, the grain is formed by a resin mixed with wood flour, while on the other hand, the grain is printed on a resin sheet. There is.

In order to solve the above problems, it is conceivable to form the screen frame of the door with synthetic resin.
In this case, there is a problem that the strength of the frame is insufficient, the net cannot be stretched properly, and the frame is distorted when the screen door is opened and closed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a vertical sliding window 1 as a fitting using the screen door 30 of the present invention, and FIG. 2 is a transverse sectional view thereof. The vertical sliding window 1 includes a window frame 10 fixed to the skeleton at the opening of the building, a shoji 20 arranged in the window frame 10, and a screen door arranged in the window frame 10 on the indoor side of the shoji 20. 30.

The window frame 10 has a structure in which an upper frame 11, a lower frame 12, and left and right vertical frames 13 are framed four times, and is a semi-external type. The upper frame 11 and the vertical frame 13 are formed by extruded aluminum members. On the other hand, the lower frame 12 is formed of an insulating member formed of an outdoor member 121 and an indoor member 122 each formed of an extruded aluminum member and a heat insulating member 123 connecting the indoor members 121 and 122 to each other. Although the heat insulating member 123 in the present embodiment is formed by injecting a synthetic resin such as urethane, the heat insulating member may be formed of one or more plate-shaped members. Such a heat insulating member is caulked at both ends in the indoor / outdoor direction by the indoor / outdoor members, thereby connecting the indoor / outdoor members to each other.

On the indoor side of the upper frame 11, a heat insulating cover 41 along the longitudinal direction is fitted and attached. Lower frame 1
The second indoor member 122 is also provided with a heat insulating cover 42, and the metal plate 14 lined with the heat insulating cover 42
An operator handle 15 that opens and closes 0 is fixed. The vertical frame 13 is also provided with a heat insulating cover 43, and the heat insulating cover 43 is configured to include an attachment 44 that engages with the latch 30 </ b> A of the screen door 30. These heat insulating covers 41, 42, and 43 form the indoor side surface of the window frame 10 by covering the indoor side of each of the frames 11, 12, and 13, and serve as a dew condensation preventing member made of synthetic resin according to the present invention. Equivalent to. Therefore, in the window frame 10, only the heat insulating covers 41 to 43 are exposed to the indoor side and are viewed inside.

The heat-insulating covers 41 to 43 are, for example, a mixture of 100 parts by weight of a thermoplastic resin, for example, polypropylene, and 100 parts by weight of wood powder of 100 mesh or more selected by crushing wood and sieving. (The mixing ratio of wood flour to resin is 50% by weight.) Further, as a compatibilizer, 1 part by weight of maleic anhydride-modified polypropylene is mixed, melt-mixed, and formed by extrusion molding. It has a color close to wood.

If wood powder having a large particle diameter of 10 mesh or less is used, it becomes difficult to uniformly mix the resin and the wood powder.
Variations in wood texture and performance are likely to occur. If the mixing ratio of the wood flour is less than 30% by weight, the wood texture becomes poor,
On the other hand, if the mixing ratio of the wood powder exceeds 70% by weight, the resin content is too small, the moldability is reduced, and the strength of the engaging portion may not be secured. In addition, since such an engaging portion is hard to touch the eyes and does not require much woody feeling, only the engaging portion is formed with extremely low mixing ratio of wood flour or without mixing at all. The strength may be improved.
For such molding, two-color molding that is common in molding of a synthetic resin can be used.
