Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raising / lowering window.

[0002]

2. Description of the Related Art In a raising / lowering window, for example, as described in Japanese Utility Model Laid-Open No. 3-108182, a spiral spring type balancer is used to assist in opening / closing a shoji screen and maintain the open position. There is.

[0003]

The raising / lowering window to which the spiral spring type balancer is applied has some practicality, but the friction resistance of the balancer itself is large and the opening / closing operation is heavy, and the spring provided for the balancer If one of the pieces breaks, the shoji will fall, which is dangerous.

[0004]

[Means for Solving the Problems] A vertical groove is provided in opposed vertical frames, and a lower end of a spring piece of a constant force spring installed at a proper position of the vertical frame is connected to a slider slidably fitted in the vertical groove, A lower support cylinder is projected from the lower part of the shoji which has an upper support piece detachably engaged with the vertical groove in the upper part, the lower support cylinder is connected to the slider, and the tip end is urged by a coil spring. A locking rod for projecting from the slider through the lower support cylinder is attached to the shoji, and a through hole for properly locking the tip of the locking rod is provided in a row in the back wall of the vertical groove of the vertical frame. The configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a raising / lowering window according to the present invention. FIG. 1 is a sectional view taken along the line AA of FIG. 8 and FIG.
B sectional view taken along line B, FIG. 3 is a sectional view taken along line EE of FIG. 2, and FIG.
6 is a sectional view taken along line CC of FIG. 5, FIG. 5 is a sectional view taken along line FF of FIG.
8 is a sectional view taken along the line DD of FIG. 8, FIG. 7 is a sectional view taken along the line GG of FIG. 6, FIG. 8 is a schematic front view showing the positional relationship of each part, and FIG. is there.

The raising and lowering window of the embodiment is provided with a fitting and killing portion 2B on the upper portion of the window frame 1A, and the lower opening is closed by the shoji 2A.
The vertical groove 4 is provided on the vertical frames 3 and 3 of the window frame 1A facing each other.
The upper support piece 5 on the shoji 2A side and the lower support tube 6 are engaged with each other, and the lower support tube 6 is a spring piece 8 of a constant force spring 7 mounted on the vertical frame 3.
The slider 9 connected to the vertical groove 4
The opening / closing operation is carried out by moving along.

Therefore, the upper support piece 5 is attached to the guide frame 10 fixed to the upper frame of the shoji 2A as shown in FIGS. The pressing spring 11 urges the vertical groove 4 to move laterally to engage the tip with the vertical groove 4, and the projecting piece 5a provided on the upper surface causes the pressing spring 11 to move laterally against the urging force. The engagement with the vertical 4 is disengaged.

That is, at the upper part of the shoji screen 2A, the upper support piece 5 is engaged with the vertical groove 4 so that the vertical frame 3 of the window frame 1A.
The upper supporting piece 5 is disengaged from the vertical groove 4 to be disengaged from the vertical frame 4, and the shoji 2A as a whole is rotated about the lower supporting cylinder 6 as a supporting shaft so as to be in a so-called inclining state. is there.

This inclining state is maintained by supporting the upper side of the shoji 2A with an arm 26 made of synthetic resin as shown in FIG. One end of the arm 26 is rotatably assembled by engaging a protrusion with a through hole provided in the vertical frame of the shoji 2A, and the other end is provided with the opening of the vertical groove 4 when the shoji is in a vertically movable state. The collar piece 27 wider than the width is provided, and the collar piece 27 is locked in the vertical groove 4 to maintain the inward falling state.

As shown in FIGS. 2 and 3, the base of the lower support cylinder 6 is fixed to the lower frame of the shoji 2A with a screw 12, and is slidably fitted in the vertical groove 4 in a vertically movable manner. The slider 9 is engaged with the slider 9 and is combined with the slider 9. The lower support cylinder 6 has a locking rod 13 projecting from the slider 9 toward the inner wall portion 4a of the vertical groove 4. The locking rod 13 is designed to be retracted into the lower support cylinder 6 against the urging force of the coil spring 15 by operating the operating piece 14 by inserting the locking rod 13.

The operating piece 14 is assembled to the shoji screen 2A by vertically movable engagement with a guide gap 17 composed of a support frame 16 and a frame part fixed to the center of the lower side of the shoji screen 2A. A pin 18 provided on the outdoor side of the operation piece 14 is inserted into the frame portion through a vertically long hole 19 provided in the frame portion, and between the pair of drive portion pieces 20 and 20 provided in the frame portion. Intervened.

Each drive part 20 has a corresponding locking rod 13.
The guide frame 2 installed on the frame part, which is installed upright on the base part of
1, and the coil spring 15 is provided between the guide frame 21 and the guide frame 21 so as to overlap each other (as a result, the locking rod 13 is urged in a direction projecting from the slider 9). ), The pin 18 is arranged between the upper sloping edges 22 and 22 provided in opposite directions, and when the pin 18 is pressed through the operation piece 14, the pin 18 descends while being pressed against the sloping edge 22. Then, each drive part piece 20 pressed at the inclined edge 22 part
Moves laterally against the bias of the coil spring 15, and as described above, the tip of the locking rod 13 retracts into the lower support cylinder 6.

The tip end of the locking rod 13 projecting from the lower support cylinder 6, that is, the slider 9 by the bias of the coil spring 15 has a through hole 2 vertically arranged in the inner wall portion 4a of the vertical groove 4.
, 23, ..., as appropriate. That is, when raising the shoji 2A, the tip of the locking rod is disengaged from the lowest through hole by operating the operating piece, and when the operating piece is released at an appropriate position, it is locked in the through hole by the bias of the coil spring 15. The tip of the rod is locked to obtain a half-opened state of the shoji.

The shoji screen 2A is smoothly moved vertically by the constant force spring 7. That is, the constant force spring 7 is constructed by fixing the upper end of the spring piece 8 to a winding drum 25 that is rotatably assembled to the base body 24 fixed to the vertical frame 3, and is drawn out from the winding drum 25. By connecting the lower end of the piece 8 to the slider 9 and removing the locking rod 13 from the through hole 23 or by the restoring force of the spring piece 8 depending on the relative relationship with the weight of the screen 2A, Ascend along the vertical groove 4 (in the case of a constant force spring whose restoring force is strong due to the weight of the shoji 2A) or hold the position (in the case of a constant force spring in which the weight and the restoring force are balanced), In any case, the shoji 2A can be freely positioned in the height direction by operating the operation piece 14 with the fingers.

[0015]

Since the present invention has the above-mentioned constitution,
It is possible to smoothly open and close the shoji screen, and further, even if the spring piece is damaged, the locking rod automatically stops in the through hole to prevent the shoji screen from falling, and a highly safe window can be provided.
