Description

Detailed Description of the Invention (Field of Application of the Invention) The present invention is directed to a sash in which glass is fitted to at least one of the front and rear sides of a frame including the upper and lower frames and left and right side frames, and horizontally spaced apart from each other in the vertical direction. This invention relates to a blind interior sash equipped with a horizontal blind consisting of a plurality of supported rows of slats.

(Background of the Invention) Conventionally, various types of double sashes with built-in blinds of the above type have been proposed for the purpose of energy saving effect.
Alternatively, the rotating mechanism is complicated, and the operating cord hangs outside the sash, which is undesirable in terms of design. In addition, since the operating distance required for raising and lowering is at least the height of the blind, there is a problem that the operation becomes complicated.

(Objective of the Invention) The object of the present invention is to solve the above-mentioned problems in conventional sashes with built-in blinds, to enable raising and lowering of the slats with a simple operation mechanism, and to prevent the operating cord from hanging outside the sash. Therefore, it is an object of the present invention to provide a blind interior sash which is excellent in appearance and in particular has a short operating distance for raising and lowering.

(Summary of the Invention) The blind interior sash according to the present invention includes a plurality of horizontally supported sashes spaced apart from each other vertically in a sash in which glass is fitted to at least one of the front and rear sides of a frame including the upper and lower frames and left and right side frames. In a blind interior sash equipped with a horizontal blind consisting of a row of slats, a lift operation knob is provided on one side frame of the sash and can be slid in the vertical direction and fixed at a desired position. The lifting cord connected to the lower plate provided at the lower end of the slat row is extended vertically upwards to the upper end of the slat row, guided horizontally within the sash upper frame, and extended to near one end of the sash upper frame. , guide this vertically downward within one of the side frames, pass it around the guide that moves up and down within the side frame using the lift control knob, guide it vertically upward, and raise the upper end of the guide. It is characterized by being fixed within the sash frame.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the blind interior sash according to the present invention. In the figure, 1 indicates a sash frame, which includes an upper frame 1A, a lower frame 1B, and left and right side frames 1C and 1D. This frame includes two front and rear glasses.
(See Figure 3) is fitted. A horizontal blind consisting of a plurality of rows of slats 3 supported horizontally at intervals above and below is housed within this sash frame. Inside the upper frame 1A, an upper box 4 of the blind is attached by a mounting bracket 5 (see Fig. 2), and a pair of ladder-shaped blinds are secured to a rotating drum 6 rotatably supported within the upper box. The slats 3 are horizontally supported by support cords 7 at intervals vertically, and a lower plate 8 is disposed at the lower end of this row of slats, and the support cords 7
The lower end of is connected to the lower plate 8. Reference numeral 9 denotes a rotating shaft, and by rotating this rotating shaft 9, the ladder-like support cord 7 is raised and lowered via the rotating drum 6, and the slat 3 is tilted. Such a mechanism itself is well known; for example, the side frame 1C
The slat may be tilted by rotating the rotary shaft 9 via the transmission shaft 11 using a rotary operation knob 10 provided on the slat, or a well-known mechanism may be used to tilt the slat in relation to the raising and lowering operation of the slat. The slat may also be tilted.

The side frame 1D of the sash is provided with a sliding part 13 having a substantially square cross section and having grooves 12 in the vertical direction, and a lift operation knob 14 is slidably mounted in the sliding part 13 in the vertical direction. engaged. As shown in FIG. 4, the lifting/lowering operation knob 14 consists of a knob 15 and a sliding member 16. The knob 15 has a female screw, and the sliding member 16 has a male screw that is screwed into the female screw. A guide 18 for pulling the screw 17 and the folded portion of the lifting cord 5 is provided.

Lifting cord 1 connected to lower plate 8 at the lower end
9 extends vertically upward to the upper end of the slat row through an insertion hole (not shown) provided in each slat 3 within the sash frame, is introduced into the upper box 4, and is inserted horizontally within the upper box 4. , is guided from the edge of the upper box 4, and is guided vertically downward along the sliding portion 13 within the side frame 1D. Next, the lift cord 19 is connected to the guide 18 of the lift operation knob 14.
The upper end is fixed to the cap 20 of the upper box 4.

In the above-described sash, the slats 7 from the lower plate 8 of the blind are sequentially folded up by operating the lifting cord 19 led out from the upper box, and the rotating drum 6 is folded up by rotating the rotating shaft 9. A ladder-like support cord 7 moves up and down through the support cord 7 to tilt the slat. The lifting cord 19 is guided to the sliding part 13 of the sash side frame 1D, passed over the guide 18 of the lifting operation knob 14, folded back, guided upward, and the end is fixed to the upper box cap 20 of the blind. Therefore, in order to fold up the blind, move the lift operation knob 14 that protrudes from the sash side frame 1D downward, and the sliding member 16 will pull the folded part of the lift cord 19 and move downward. To do this, the blinds are folded up sequentially starting from the bottom board. At this time, since the lifting cord 19 is folded back by the guide 18 and the end is fixed at the upper part, the lifting cord 19 is twice the moving distance H/2 of the knob, that is, the distance H
It will only be folded up. (Fig. 5, 6
(See figure) Turn the knob to turn the knob 15.
Since the protruding part of the sash is fixed between the sliding member 16 and the sliding member 16, the blind does not fall down due to its own weight. On the other hand, the rotation operation can be performed by rotating the rotating shaft 9 using the rotation operation knob 10 or the like as described above.

Although the illustrated example has been described as a blind having an upper box 4, the upper box 4 may be omitted, and a blind rotation mechanism etc. may be provided directly on the sash upper frame 1A. In this case, the end of the lifting cord 19 may be fixed to the sash frame, and may be at a position higher than the position of the knob 15 when the slat is lowered to the bottom. Furthermore, the lifting cord 19 does not need to be passed through the insertion hole of each slat, and if other means to prevent each slat from moving left and right (for example, by restricting it with the frames on both sides of the sash) are provided, the slat It may be guided directly upward without passing through the insertion hole. With this blind, the lifting and lowering operations are heavier than normal mechanisms, but the balance weight
It is also possible to add a spring or the like as an auxiliary operating means.

In addition, the sash of the present invention is a sash in which a blind is fitted, or a movable shoji inside a sash frame framed in a rectangular shape, etc., and the glass of the sash or movable sash does not necessarily need to be double-sided inside and outside. Instead, it may be either the inside or the outside.

(Effects of the Invention) As described above, the blind interior sash of the present invention allows the blind to be operated from outside the sash, and in addition, the operation code can be placed outside the sash without requiring a complicated mechanism as in the past. It doesn't even sag. In addition, the operating distance is only half of the height of the blind, that is, approximately half of the height of the satsushi.
There are no drawbacks such as not being able to reach the knobs.
