Description

Detailed Description of the Invention (Field of Application of the Invention) The present invention relates to a case in which glass is fitted in at least one of the front and rear sides of a frame including an upper and lower frame and left and right side frames, at intervals vertically. This invention relates to a blind interior droplet equipped with a horizontal blind consisting of a plurality of rows of horizontally supported slats.

(Background of the invention) Traditionally, the purpose was to save energy.

Various types of double sashes with built-in blinds of the above type have been proposed, but the mechanism for raising, lowering, or rotating the blinds added inside the sash is complicated, and the operating hood hangs outside the sash, which is undesirable in terms of design. Such shortcomings have grown. In addition, since the operating distance required for raising and lowering is at least the height of the blind, there is the problem that the operation becomes complicated.

(Object 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 operation cord from hanging outside the sash. Therefore, it has an excellent appearance, especially,
Blind interior frame with short operating distance for lifting and lowering.
It is possible to provide services.

(Summary of the invention) The blind interior sash according to the present invention is as follows.

A horizontal blind consisting of a row of horizontally supported slats separated by a distance of KM above and below is installed in a sash in which at least one of the front and rear sides of the frame including the upper and lower frames and the left and right side frames is fitted with glass. In the blind interior sash, an outer operating knob that can be slid vertically and fixed at a desired position is provided on one side frame of the droplet, and is provided at the lower end of the row of slats of the blind. Extend the lifting cord connected to the lower plate vertically upwards to the top of the slide row, guide it horizontally within the top frame of the top frame, extend it to near one end of the top frame of the top frame, and then connect it to one of the above 4 in the vertically downward direction within the side frame, and the guide that moves up and down within the side frame by the above-mentioned lift operation knob 4 is passed around and guided vertically upward, and its upper end is placed on the top of the sushi frame. It is characterized by being fixed.

(Embodiments of the invention) An embodiment of the invention will be described below with reference to one drawing.

Fig. 1 is a front view showing an embodiment of the blind interior according to the present invention. , ID, and the front and rear glasses 2 (see Fig. 3) are fitted into this frame, and consists of a plurality of rows of slats 3 supported horizontally at intervals above and below within this frame. Built-in horizontal blinds. The upper frame IAnKR and the upper box 4 of the blind are held by the hugging Zuragedato 5,
(See Fig. 2) A pair of ladder-shaped support cords 7 secured to a rotating drum 6 rotatably supported within the upper volks.
The slats 3 are supported horizontally at vertically spaced intervals, and a lower plate 8 is disposed at the lower end of this row of slats, and the lower end of the support hood 7 is connected to the lower plate 8. 9#
From K, rotate this rotating shaft 9 with one rotating shaft.

A ladder-like support hood 7 is raised and lowered via a rotating drum 6 to tilt the slats 3. Such a mechanism itself is well known, and for example, it is possible to rotate the rotary shaft 9 via the slow shaft 11 using the rotary operation knob 10 provided on the side frame ICK, or to tilt the slat. Alternatively, a well-known mechanism may be used to perform the tilting operation of the slat in conjunction with the raising and lowering operation of the slat.

A sliding part 13 having a C-shaped cross section and having grooves 12 in the vertical direction is provided on the side frame IDVC of the sushi board, and a lift operation knob 14 slides in the vertical direction on this sliding part 13. freely engaged.

As shown in FIG. 4, the lifting/lowering control knob 14 consists of a knob 15 and a sliding member 16. The knob 15 has a female thread, and the moving member 16 has a male thread that is screwed into the female thread. Guide 1 that pulls the screw 17 and the folded part of the lifting cord 5
8 is provided.

Lifting hood 19 connected to lower plate 8 at the lower end 9
Insertion holes (not shown) provided in each slur) 5 in the frame body
extending vertically upward through the slat row to the top of the slat row;
The zero-order lifting cord is introduced into the upper box 4, guided horizontally within the upper box 4, guided from the edge of the upper box 4, and vertically downward (guided) along the sliding part 13 within the side frame 1D. 19 is a guide 18 for the lift operation knob 14
4 vertically upwardly around the upper box 4, and its upper end is fixed to the cap 20 of the upper box 4.

In the above-mentioned sash, the slurry door is folded up one by one from the lower plate 8 by operating the lifting cord 19 led out from the upper box, and by rotating the one-rotation shaft 9, the blind is raised one by one through the one-rotation drum 6. The ladder-like support cord 7 moves up and down.

It is designed to tilt the slat.

The elevating hood 19 is guided to the sliding part 13 of the sash side frame 1D, passed through the guide 18 of the elevating/lowering knob 14, is turned back, guided upward, and has its end fixed to the upper polycrystalline scaffold 20 of the blind. Therefore, in order to fold up the blind, move the lift operation knob 14 that protrudes from the side cover 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, the lifting cord 19Fi and the guide 18 fold and shield the light.

Since the end is fixed at the top, it can be folded up twice as far as the knob moves. (See Figures 5 and 6) As the knob rotates, the knob 15 and the sliding member 16 engage the protrusion of the sash and are fixed.
The blind does not fall under its own weight, and the 0-rotation operation can be performed by rotating the rotary shaft 9 using the rotary operation knob 10 or the like as described above.

In the illustrated example, the explanation has been made as a blind that includes the upper box 4, but the upper box 4 may be omitted, and a rotating mechanism for the upper frame 1AK of the blind may be provided directly.

In this case, part of the elevating hood 19 may be fixed to the sash frame, and the elevating hood 19 does not have to be passed through the insertion hole of each slat, but other means can be used to prevent each slat from moving from side to side. (For example, when the slat is restricted by the side frames of the slat, etc.), it may be guided directly upward without passing through the insertion hole of the slat.

Although the lifting and lowering operation of this blind is heavier than a normal mechanism, it is also possible to add a balance weight 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. Not.

Only one of the inside and outside may be used.

(Effects of the Invention) As described above, the plastic/fnd interior sash of the present invention allows the blind to be operated outside the sash, and in addition, it does not require a complicated mechanism unlike the conventional one, and an operating code can be used. It doesn't droop outside, either.

Since the operating distance is only half the height of the blind, that is, approximately half the height of the sash, there are no drawbacks such as not being able to reach the knob.
