Description

[Detailed description of the invention] In Japanese Utility Model Publication No. 57-55494, the present applicant attached a bracket to the vertical stile of the upper window arranged above the lower fitted window, and fixed one end to the bracket. The rope is laid over a guide pulley disposed at the top of the opening frame, a counterweight is fixed to the tip of the cable, and a vertical guide section is extended to the lower end of the upper inclined guide section that slopes downward toward the outdoor side. A guide rail formed by the above-mentioned guide rail is disposed in a vertical frame of the opening, and a roller that rolls within the guide rail is mounted on the bracket, and
We have proposed a projecting window/single raising/lowering window characterized by a stopper for the rotating wheels being disposed on the guide rail so that it can freely appear and retract, but a counterweight is attached to the upper vertical stile. Since the mounting position of the counterweight is restricted, it may be difficult or impossible to install the above-mentioned projecting window and single-side up/down window in some cases.

The present invention is an improvement on these points, and includes guide pulleys 2 disposed on the vertical stile 1 of the upper window B disposed above the lower closing window A and the upper sill of the opening frame C, respectively. , 3, and one end of the lifting cable 4 is connected to the top of the opening frame C or the building frame, and the other end is attached to the lower part of the window A or the opening frame C or the building frame. The guide rail 6 is wound around the winding drum of a known speed regulator 5 attached to the winding drum, and has a vertical guide section 6B extending from the lower end of the upper inclined guide section 6A which is inclined downward toward the outdoor side. A guide pulley mounting bracket 2 disposed on the vertical frame 7 of the opening frame and for attaching the guide pulley to the vertical frame 1.
A is equipped with a roller 8 that rolls within a guide rail 6, and a stopper 9 for the roller 8 is arranged so as to be able to appear and retract from the guide rail 6. When closed, the upper window is located on the same plane as the lower closing window, and when opened, the upper window is lowered in front of the lower window, and if necessary, the upper window is stopped in the middle of the lifting process. The object of the present invention is to provide a projecting window and a single-side-up/down window which can be used as a projecting window, and a window elevation control device can be attached to a bottom fitting window, an opening frame, or any part of a building frame.

Note that the opposing surfaces of the lower stile 10 and the blind 11 of the lower window B are:
It has the same slope as the upper inclined guide part 6A of the guide rail 6, and the lower stile 10 is equipped with a rolling wheel 12 that rolls on the slope of the blind 11, and when the upper window B is lowered. , the upper and lower ends thereof are configured to descend in parallel while being pushed out to the outside of the room.

The guide pulley 3 is attached to the upper frame 13 of the opening frame C, and an airtight sealing material 14 is attached to the opening frame C, which is pressed to the frames around the four sides of the upper window B when the upper window B is closed. There is.

In the figure, 17 is a support rod that holds the upper window B in the protruding position.

10 to 12 show the guide rail 6 of the stopper 9.
A disc-shaped stopper 9 is disposed so as to be freely retractable and extend over a side piece of the guide rail 6 and a through hole bored in the vertical frame 7 to which the guide rail 6 is attached. The operating rod 18 attached to the vertical frame 7 is loosely inserted into the slot 20 provided on the back side of the box 19 attached to the vertical frame 7.
A bullet 21 is interposed between the box 19 and the stopper 9, and its urging force always presses the stopper 9 so as to enter the guide rail 7.

On the other hand, a rectangular flange piece 22 is disposed on the operating rod 18, and when the longitudinal direction of the flange piece 22 coincides with the longitudinal direction of the slot 20, the flange piece 22 penetrates through the slot 20 and the operating rod 18 The collar piece 22 is configured so as not to penetrate through the slot 20 when the collar piece 22 is rotated by 90 degrees.

Therefore, as shown in FIG. 10, normally, the operating rod 18 is moved back against the force of the bullet 21 so that the stopper 9 retracts into the box 19, and the collar piece 22 is inserted into the slot 20.
It is fixed to the back of the box 20 so as to be perpendicular to the
When operating the stopper 9, the operating rod 18 is
When rotated by degrees, the collar piece 22 passes through the groove 7L 20, and the operating rod 18 is automatically advanced by the force of the ammunition 21.
A stopper 9 projects into the guide rail 6.

(See FIG. 11) The pulley 2 is hinged to a bracket 2H, and the pulley 3 is also hinged to a bracket 3a attached to the upper leg of the opening frame C.

A bracket 23 is attached to the frame or building frame, and the end of the lifting cable 4 is fixed thereto.

Reference numerals 24 and 25 denote guide pulleys for guiding the lifting cable 4 to the speed regulator 5, which are arranged in the vertical frame 7 and the blind 11 at the corners of the opening frame and the lower closing window, respectively. may be installed in a nearby building so that it can be controlled remotely.

5a is a handle of the speed regulator 5, and 26 is a bracket and a bar for mounting the speed regulator.

Since the present invention is designed as described above, when the upper window B is used as a raising/lowering window, after the stopper 9 is moved out of the guide rail 6, the winding drum and the same drum in the speed regulator 5 are When the locking device was released, the lifting cable 4 that had been wrapped around the drum was unwound and attached to the mounting bracket 2a of the guide pulley 2 arranged on the vertical stile 1 of the upper window B. An upper inclined guide portion 6A in which the rollers 8 are inclined downward toward the outdoor side of the guide rail 6;
As a result, the upper window B is moved diagonally forward in parallel as shown by the chain line in FIG. As the upper window B moves, the upper window B vertically lowers and lowers in front of the lower window A as shown by the chain line in FIG.

At this time, the speed regulator 5 controls the rotational speed of the winding drum around which the lifting cable 4 is wound, thereby preventing the upper window B from descending rapidly and allowing the upper window B to descend smoothly.

Next, when the upper window B is to be raised, the intended purpose can be achieved by operating the handle 5a of the speed regulator 5 and winding up the lifting cable 4 with the winding drum.

At this time, even if the operation of the handle 5a is interrupted while the upper window B is rising, the winding drum is locked by the locking device and there is no risk of it being reversed, so the upper window B is stopped at the position during the rise. .

Thus, when the upward movement of the upper window B has been completed, the upper window B has its wheels 8 and the upper inclined guide section 6 on the guide rail 6.
In cooperation with A, it moves in parallel toward the indoor side, and the four inner side surfaces of the stile are pressed against the airtight material 14 attached to the opening frame C, thereby maintaining airtightness.

Next, when the upper window B is used as a projecting window, the stopper 9 is advanced into the guide rail 6, and when the upper window B is lowered as described above, the rolling wheels 8 that roll down within the guide rail 6 impinges on said stop 9 and prevents further downward movement of the upper window.

When the upper window B is pushed toward the outdoor side in this state, the upper window B is projected toward the outdoor side using the roller 8 supported by the stopper 9 as a fulcrum as shown by the dotted line in FIG. 2 and the chain line in FIG. , which functions as a projecting window.

In this way, according to the present invention, with a simple structure, the upper window located on the same plane as the fitted lower window or the upper part of the frame is used as a single-side up/down window, and as needed. Yes. The upper window can be used as a projecting window.

In addition, in the projecting window/single-up/down window proposed by the present applicant in Japanese Utility Model Publication No. 57-55494, a counterweight was attached to the upper window, whereas in this proposal, a counterweight was attached to the upper window. A lifting cable spanned over guide pulleys 2 and 3 respectively arranged on the vertical stile 1 and the upper part of the opening frame C, and one end of which is connected to the upper part of the opening frame C or the building frame. The other end of the winding drum of the speed regulator 5 is wound around the winding drum of the speed regulator 5, and the speed regulator 5 controls the raising and lowering of the upper window B. Therefore, the operation is simple. The present invention has many advantages, such as being very convenient because the lower window A, the opening frame C, and the opening frame C can be installed at any position on the building frame.

Note that FIGS. 14 and 15 show an embodiment of the speed regulator 5, in which a winding drum 28 is rotatably mounted in a housing 27, and a stopper gear 29 is concentrically mounted on the drum 28. A funnel-shaped speed control section 30 is further attached, and the rotational speed of the winding drum is adjusted according to the viscosity of the liquid contained in the funnel-shaped speed control section 30.

In the figure, numeral 31 is a hoisting handle attached to the drum 28.

A stopper pawl 32 that meshes with the gear ring 29 is pivotally supported on the housing 27, and an operating knob 34 is raised from the pivot 33 and the pawl 32 and slidably inserted into the housing 27.
A tension spring 35 is tensioned between them, and the urging force of the spring 35 causes the stopper pawl 32 to mesh with the gear ring 29.

Therefore, when the winding handle 31 is rotated in the winding direction, the winding drum 28 rotates while its tooth ring 29 and stopper pawl 32 engage and disengage, and the lifting cable 4 is wound around the winding drum 28 to raise the upper window B. It is something that forces you to do something.

At this time, even if the hand is released from the winding handle 31 midway, the stopper pawl 32 engages with the gear ring 29 to prevent the winding drum 28 from being reversed.

Further, when the operating knob 34 is operated to rotate the stopper pawl 32 to the position shown in FIG.
rotates in the unwinding direction of the lifting cable 4, and the upper window B automatically drops.
