Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a sash operator having a fully automatic opening/closing function controlled by hydraulic pressure.

(Prior art) Conventionally, the prior art provided as an opening/closing device for consecutive windows includes:
Japanese Utility Model Publication No. 56-2783, filed earlier by the same inventor as this invention, discloses a window opening/closing system in which a window is opened and closed by the forward and backward movement of an irreversible chain retracted from a window opener equipped with a DC motor near each window. An electric window opening/closing device disclosed in Japanese Utility Model Publication No. 13155/1983 discloses an electric window opening/closing device disclosed in Japanese Utility Model Publication No. 52-13155, and a device for returning a smoke exhaust window by operating a wire using a double pulley in which both ends of a damper bar are pivotally connected to both edges of a window and an opening frame. However, in the former case, when the window is closed too much, it causes troublesome adjustment of the filtering power applied to the DC motor, and the individual windows
Expensive equipment such as reduction gears and electric motors in the D-opening device is difficult to implement due to smoke pollution, and the latter requires manual rotation of the handle on the operating box each time the window is closed.
Unnecessary wasted time and wasted effort have become problems.

Furthermore, apart from the domestic technology mentioned above, a pneumatic multiple window opening/closing device (German Patent No. 705039, 1941) has been disclosed as foreign prior art, but this device uses compressed air as an energy source. Equipment for this purpose, that is, an air compressor, is required, and if this equipment is not installed in a place where it cannot be seen by the public (in a separate room), it becomes an aesthetic problem, and the exposure of the opening/closing mechanism around windows has become a problem in recent years, as interior decoration in rooms has become more aesthetically pleasing. Coupled with the soaring cost of equipment, such as the reversal of the course, it is rarely seen on the market.

(Problem to be solved by the invention) In a high window opening/closing device, a stay damper or a gas spring or other spring is used to lock another window closing member or a wire winch. Most methods open the window by disassociating it by pushing a button, but on the other hand, the method of closing the window requires manually rotating the handle of the winding device, which wastes time, wastes effort, and cuts the wire. Decrease in function due to natural relaxation (window flapping) is an annoying and constant problem.

(Purpose of the Invention) In recent years, the interior and exterior decoration of buildings has made remarkable progress. In particular, windows and their surroundings become the focus of attention as they are particularly conspicuous parts of interior walls. Therefore, this invention not only promotes the above-mentioned beautification, but also
The main objective is to eliminate wasted time and effort in winding a wire rope between a window and a winch when closing a window, and to provide a fully automatic satsushi operator that can be safely and easily operated even by women and men.

(Means for Solving the Problems) The fully automatic satsushi operator using hydraulic pressure control according to the present invention is composed of a second power source, and in an emergency, it operates with top priority given to reception by disaster prevention centers and smoke detectors, etc. Connect the piping of the hydraulic unit, which is operated by commands from the internal control panel, to the cylinder on the window lock device side, and connect the hydraulic unit on the ceiling side, which is connected to the operation box at hand and the hydraulic unit on the ceiling side, respectively, with a secondary power source.
It is characterized by being connected to separate left and right sills for opening and closing windows.

(Function) [Fenture] Normally, the fenestration angle is 15 degrees 30 displayed near the fenestration angle switch located on a hand-held operation box fixed to a wall pillar or wall surface.
When you select an opening angle by turning the knob to any one of the 45 degree opening angles and pressing the operation button, the window will receive power from the primary power supply installed inside the ceiling and A control panel connected to the operation box and a secondary power source sends commands to another hydraulic unit installed on the same ceiling side, but first, the accumulator inside the hydraulic unit accumulates pressure without rotating the motor. Due to the movement of the hydraulic pressure, the rods of each hydraulic cylinder on the window locking device side (one installed on each window) are retracted, and at the same time, the connecting rod extending from the Rondo end and parallel to the hydraulic cylinder is also moved. , the plurality of hooks protruding from the connecting rod will separate from the contact with the protrusions, the same number of which are hung from the edge of the window, but this is the first condition for opening the window. Regardless of the selection of the opening angle of the selector switch with a knob that is operated first, when the upper part of the operating chain (open) mark is pressed, the switch that is integrated with the connecting rod starts operating immediately. This is the separation action from the window side projecting piece due to the movement of the hook, and only through this action the closing window is released from the hook and becomes ready to be opened. When the agreed locks are released all at once in this way, the piston rods of the left and right hydraulic cylinders for opening and closing the windows extend due to hydraulic action and the window opens, but this two-step action is carried out by the side of the window locking device. Hydraulic cylinders and left and right hydraulic cylinders for window opening/closing are attached to the left and right hydraulic cylinders, respectively.
This provides various functions that operate in stages, such as stopping at an arbitrary set fenestration angle.

When the window opening is stopped, the operation button (close) mark display 2 is pressed to increase the hydraulic pressure of the left and right hydraulic cylinders for opening and closing the window. The piston rods of the left and right hydraulic cylinders keep it safe and strong.

The above describes the operation when windows are opened in normal times using only manual operation (pressing the operation button and operating the changeover switch knob), but in the event of an emergency due to a man-made disaster, the operation of the disaster prevention center and smoke detectors etc. is explained. The control panel is configured to operate the hydraulic unit with top priority given to reception.

[Closed window]

When you press the operation button with the (closed) mark located approximately in the center of the operation box, the secondary power source rotates the pump motor in the hydraulic unit via the control panel to increase the oil pressure, allowing the left and right windows to open and close. The piston rod of the hydraulic cylinder retracts and gently closes the open window when it becomes parallel to the window opening frame, that is, when the window becomes vertical, the limit switches of the left and right hydraulic cylinders issue a command and the piston rod In order to stop the contraction of the window, the solenoid valve is closed and the hydraulic pressure is stopped, and the window is instantly stopped together with the rod.The rod in the hydraulic cylinder on the side of the window locking device extends, and a hook protrudes integrally with the connecting rod. The window can be completely locked by being hooked onto a protrusion hanging from the edge of the window.

Note that the (stop) button located at the bottom of the operation box stops the switch function in the control panel connected to the operation box and stops the control of the hydraulic unit, and the window opening/closing function is completely disabled. It is provided to help maintain safety during maintenance and adjustment work.

(Example) A fully automatic sash operator (hereinafter referred to as a fully automatic window opening/closing device) using hydraulic pressure control according to the present invention is installed in a series of windows.
The embodiment will be explained as follows based on the drawings.

The first illustration is an overall schematic installation diagram showing an example of a case where the fully automatic window opening/closing device according to the present invention is installed in a row of windows.

1 is a control panel installed on the ceiling side, connected to the 2nd rW, source 1C (alternating current), and equipped with a switchboard (not shown) for controlling the hydraulic unit. DC-2 is used for circuits that connect to emergency signals (highest priority), smoke detectors, operation buttons for opening windows, etc.
A small current of 4VC (24 volts DC) is distributed.

3 is a hydraulic unit, which, like the control panel 1, is installed internally on the ceiling side and connected to the control panel 1 by a secondary power source 2C. Both are not shown] and serve as a source of hydraulic motion for opening and closing the window and locking the window when it is closed.

The hydraulic piping P extending from the pump in the hydraulic unit 3 is connected to a window opening/closing cylinder 3A and another window closing/locking cylinder 3B attached on both sides of the continuous window W, respectively, and the oil supply switching operation is performed. The solenoid valve and control valve are responsible for this role.

A changeover switch 5 with a knob is rotatably pivoted on the outer surface of an operation box 4 provided near the hand below the continuous window window W, and the display position is 15 degrees, 30 degrees, and 45 degrees. A relay (not shown) is arranged in such a way that once the extension of the rod of the window opening/closing cylinder 3A is stopped, the extension of the rod of the window opening/closing cylinder 3A is changed in three stages using a limit switch (not shown).

Next, when the push button 6 with the (open) mark displayed above the chain on the surface of the operation box 4 is pressed, the hydraulic unit 3 is activated by a minute current.
The oil is stored under pressure without operating the motor inside.
After retracting the rod of the window closing/locking cylinder 3B by pressure, it serves as a command to extend the rod of the window opening/closing cylinder to open the window.

In addition, when the push button 7 with the (close) mark in the center is pressed, the motor of the pump in the hydraulic unit 3 is rotated to raise the hydraulic pressure, and the rod of the window opening/closing cylinder 3A is first retracted. As soon as the continuous window W is closed in the vertical direction, a limit switch (not shown) is activated to close the window R.
In this case, the rod of the window closing lock cylinder 3B is extended, and the connecting rod extending from the rod is attached to the protruding piece W1 hanging down from the edge of the continuous window W. The integrally protruding hook 3D can be engaged in an abutting manner to completely lock the window in the closed state.

Reference numeral 8 denotes a push button with a (stop) mark displayed, which is used to stop the operation of the control panel 1 and the hydraulic unit 3 by pressing it.

The form of the hook 3D may be either an inverted-shaped or inverted-U-shaped rod integrally connected to the connecting rod 3C, or a plate-like body, and is hung vertically from the edge of the continuous window W. It is only necessary that the protruding piece W1 can be abutted and latched, and the feeding condition is that it should not be easily bent.

(Effects of the Invention) According to the present invention, if the hydraulic system is installed to sufficiently deal with leakage, as outlined in the (Objective of the Invention) section, it will be possible to improve the aesthetic appearance of the area around the window and to close the window. In some cases, the wire rope winding operation does not require full heat, which eliminates wasted time and effort, and eliminates the need to install an air compressor such as a live-powered air compressor in a conspicuous location. To easily and labor-savingly open, close, and stop work of consecutive windows.
