Description

Description: BACKGROUND OF THE INVENTION (Field of Industrial Application) The present invention relates to a fully automatic window opening / closing device by hydraulic (hydraulic) control, and more specifically, can hold and release a window opening / closing damper and the other window closing. The window control damper was connected with an oil supply pipe from a hydraulic unit linked to the control panel in the ceiling, and the concealment type indication that the window could be opened and closed and the window locked automatically by the button operation on the operation box was provided. Device.

(Prior Art) Conventionally, a window opening / closing device disclosed in JP-A-53-19660 as a prior art uses a hydraulic unit. However, a window opening / closing damper is provided on one side for each window. Therefore, a horizontal window tends to damage the hinge due to a significant uneven load, and the operation box that combines the pump, oil tank, handle, etc. is bulky and must be installed at the window that is extremely easy to see. It is a drawback.

Further, the trunk lid opening / closing device disclosed in Japanese Utility Model Laid-Open No. 2-9267 is a device mainly composed of a pneumatic unit, and requires a large space for an air supply tank and a lock mechanism. In this case, the equipment could not be installed at all and was limited to a large bus with a trunk room.

Furthermore, Japanese Utility Model Laid-Open Publication No. 52-3138 (Emergency door opening / closing device)
And Japanese Utility Model Application Laid-Open No. 2-89187 (window opening / closing device) are also disclosed, but the former is a damper for opening and closing a door with multiple conduits for gas supply and discharge. Also, since the locking claw suction on the wall side when closing the door is also used, the cost of arranging the necessary members for the opening and closing device of the continuous window increases, and failures and troubles easily occur, and in addition to the troublesome inspection, Each of the linking members is complicated and bulky to conceal in a room together with the gas cylinder, so that the members are easily noticeable, and this is not practical in the room due to aesthetic problems.

In addition, the latter is a device that opens and closes the window using a well-known double pulley device that is a combination of a wire and a pulley, making full use of electric power, but the constraint of the window at the time of closing the window is one side pressure contact by the rocking body, If a gust or storm hits hard, it cannot be pressed and has the disadvantage of being the worst fenestration, and is not seen at all in the market.

(Problems to be Solved by the Invention) In the window opening / closing device, the window opening means requires a labor by the release direction urging spring such as the stay damper or the gas spring for the window unlocked by the push button operation. On the other hand, the window closing means, on the other hand, is mostly a primitive method of manually winding a rope around a drum until the window is closed, and in recent years the size of the window and the number of windows for smoke exhaustion have increased. Among them, wasted time and labor required for closing the windows and functional deterioration due to natural relaxation of the ropes (fluttering of windows and infiltration of rainwater under strong winds) are serious problems as well as cooling and heating effects in building management. ing.

(Object of the Invention) In recent years, the appearance of indoor and outdoor buildings has been remarkably improved, and especially when installing a switchgear in windows and the surrounding area that are easily visible, it is necessary to promote concealment and maintain the aesthetic appearance. A window opening / closing device that completely eliminates the problem of inefficiency and labor in the window closing means, and at the same time, completely and completely retains the window by safe and simple operation, because it cannot be implemented. Try.

(Means for Solving the Problems) A fully automatic sash operator by hydraulic control according to the present invention provides a window opening / closing device using a hydraulic damper, the window opening / closing damper, and the edge of the window to hold the other window closed. The pipe that feeds oil to both the window control damper, which is connected to the connecting rod that integrally connects the stopper that comes into contact with the projection provided on the wall and the ceiling side, is connected to the hydraulic unit in the ceiling In addition, the wiring for the secondary power supply from the control panel in the ceiling connected with the wiring for the primary power supply (AC circuit) to the hydraulic unit, the operation box and the emergency dispatch command room installed elsewhere, respectively (DC circuit).

(Function) [Opening window] Turn the knob in the direction showing the three opening window angles of 15 ° 30 ° 45 ° displayed near the changeover switch on the operation box installed on the wall post or the wall under the window. When the window angle is selected and the operation button is pressed, power is supplied from the primary power supply wiring (AC circuit) installed inside the ceiling, and the secondary power supply wiring (DC circuit) is supplied from the operation box. The control panel connected by
A command is sent to another hydraulic unit installed on the same ceiling side by wiring (DC circuit) for supplying secondary power,
First, without moving the motor by the action of the accumulator in the hydraulic unit, the stored hydraulic pressure is moved to retract the rod of the window-stopping damper (one per window). Since the connecting rod integrally connecting at least two stoppers also moves, it is separated from the same number of protrusions as the above-mentioned stoppers hanging from the edge of the window, so that all the stoppers and the protrusions do not come into contact with each other, Thereafter, the window is smoothly opened along the first window opening angle by the operation of the window opening / closing damper.

Therefore, even in the case of a single window or a multi-window, as the first stage of the window opening, the window stop damper is first started to release the maintenance of the window closing by the contact between the projecting piece and the stopper. It is a mechanism that operates in two stages.

When the window is stopped, the window is held by the pistol rod of the window opening damper unless the operation button (close) mark for rotating the pump motor in the hydraulic unit is pressed to increase the oil pressure of the window opening / closing damper. Be maintained in cooperation.

Next, in the event of an emergency such as a fire or earthquake,
The control panel is designed so that the hydraulic unit can give priority to the reception from other places away from the window opening / closing device, such as the disaster prevention center (emergency dispatch command room) and smoke detectors, which are installed elsewhere, so that the window can be opened. It is configured.

(Closed window)

If you press the operation button of the display mark (closed) on the operation box,
The pump motor in the hydraulic unit rotates through the control panel by the wiring (DC circuit) for the secondary power supply, raises the hydraulic pressure, and gradually retracts the piston rod of the window opening / closing damper to open the window. Pulling in the closing direction and when it is parallel to the window opening frame, the limit switch of the window opening / closing damper issues a command and closes the solenoid valve to stop the piston rod from retracting and stops the oil pressure. Both windows stop instantly.

Then, the rod of the window-stopping damper extends, and the lateral movement of the connecting rod with the stopper connected to the rod abuts on the same number of protrusions as the stoppers vertically provided from the edge of the window. Since the rod stops when the widths overlap, the projecting piece on the window side is blocked by the stopper and the window cannot be opened.

Therefore, in recent large windows and horizontally long windows, unless the number of the stoppers and the protruding pieces is increased, the closing of the window cannot withstand a strong moment (gust, strong wind).

(Function stopped)

When the (stop) button at the bottom of the operation box is pressed, the switch function in the control panel connected from the operation box stops and the control function of the hydraulic unit is interrupted. It is provided to stop temporarily and to help maintain safety during maintenance and adjustment work.

A changeover switch 5 with a knob is provided on the outer surface of the operation box 4 fixed to the window to temporarily stop the window angle at a three-stage display position of 15 degrees, 30 degrees, and 45 degrees. A relay (not shown) is provided to temporarily stop the rod extension in three stages by a limit switch (not shown).

The push button 6 with an (open) mark on the outer surface of the operation box 4 depresses the rod of the window blocking damper 3B by the pressurized hydraulic pressure stored in the hydraulic circuit 3 through the DC circuit through a minute current without operating the motor in the hydraulic unit 3. Then, after releasing the restraint, the rod of the window opening / closing damper 3A is extended to perform a window opening command.

Further, the push button 7 with the (closed) mark rotates the motor of the pump in the hydraulic unit 3 by pressing to raise the hydraulic power, and first, as a first step, retracts the rod of the window opening / closing damper 3A to open the window W. As soon as the rod is stopped by the action of a limit switch (not shown) as soon as it is closed in the vertical direction, the rod of the damper 3B for window control is extended as the second stage, and is suspended from the edge of the window W. The stopper 3D integrally protruded from the connecting rod 3C connected to the rod abuts on the protruding piece W1 in a contact state (a state in which both widths overlap), so that the window is completely fixed. , It will be in a state of stopping against accidents (gusts, strong winds, vibrations, etc.).

Reference numeral 8 denotes a push button for displaying a (stop) mark, which stops the operation of the control unit 1 and the hydraulic unit 3 entirely, and is used for repair and inspection.

The form of the stopper 3D may be any of an inverted L-shaped or inverted U-shaped rod or a plate-like body integrally connected to the connecting rod 3C, and a protruding piece W1 suspended from an end of the continuous window W. Is required to have sufficient rigidity to withstand the wind pressure such as strong winds and earthquakes.

Furthermore, together with the damper 3B for stopping the window and the connecting rod 3C, it is concealed in the space between the window edge and the window opening frame.
