Description

[Detailed description of the invention] (Industrial application field) This invention uses a non-reversible chain to allow for opening by protruding from below (hinge axis is on the top side) and pushing down from above (hinge axis is on the bottom side). This invention relates to an opening/closing tuning device for multiple windows.

(Prior technology) The fire regulations, which were established to prevent death by suffocation due to smoke, which is the most dangerous cause of fire, have been revised to require the installation of manual opening/closing devices. We have made a change in the early implementation of possible devices. In other words, the return device for smoke exhaust windows that used a double pulley device (Japanese Utility Model Publication No. 13155/1983), which was provided in the early days, was designed to prevent the adjacent window from opening or closing unless the end window completes opening or closing. Because the structure does not shift to operation, the time required to open and close is directly proportional to the number of windows.
It was impossible to open the window quickly, and the time required to wind the wire to close the window was extended, resulting in an immeasurable waste of effort.

Next, a US patent that allows for simultaneous opening and closing.
In the window opening/closing device disclosed in Publication No. 610499 (1898), a sub-cable branched from one main cable and connected to each window works in conjunction with the main cable, allowing all windows to be opened all at once in synchronization. However, since the excessive torque (over-turning) caused by handle operation, which tends to occur at the end of the window closing, cannot be controlled by hand, the branch cables tend to stretch in a tangled manner, so each window is completely blocked when fully closed. As a result of imperfections, incompletely closed windows are a problem due to wind and rain infiltration.

(Problem that the invention aims to solve) When using a multiple window opening/closing device, if the individual windows do not fully close all at once, gaps will be created between the windows and the opening frame, allowing wind and rain to enter. This can be a problem when it comes to air conditioning and heating, and since most of the windows are located at high places, adjusting them can be a nuisance. Furthermore, if we do not provide a simple and robust device that has the ability to quickly manually open windows in order to comply with laws and regulations, and that opens and closes each window evenly while synchronizing each window, we will not be able to comply with the law and meet the demands of the customer base. There is an unresolved problem that it cannot be answered.

(Purpose of the invention) In order to solve all the unresolved problems mentioned above, it has a unique combination configuration, and it is possible to easily install the existing multiple windows and various parts, and it is a labor-saving construction that meets the regulations. The main purpose of the present invention is to provide the market with a multi-window opening/closing tuning device that is robust and suitable for various conditions, and that provides appropriate usage effects through simple operation at a low price.

(Means for solving the problem) The multiple window opening/closing synchronization device according to this invention protrudes from and retracts from the window opener disposed on the horizontal frame of each window opening in the multiple window, and the tip is pivoted to the window edge. The caterpillar gear is fixed to the shaft of the chain wheel that engages the irreversible chain, and the energy storage is connected to the extreme end of a polygonal horizontal shaft that connects each caterpillar that meshes with the caterpillar gear via a universal joint. The end of the constant force spring is not fixed on the first reel in the container, but is tightly wound in its original shape, and the other end is pulled out and fixed on another second reel inside out, and the S is wound between both reels.
It is characterized by having a cable stretched between a cable reel which is arranged in a shape of a letter, and which is integrated with a second reel, and an operating device which has opening and stopping functions by pressing a separate button. be.

(Function) [Window Window] To explain the function in detail while giving an auxiliary overview of the combination structure of this invention, each window has a buffer bomb (known as a stay damper) connected to the left and right opening frames. A non-reversible chain connects the window switch installed between the center of the window edge on the opposite side of the hinge axis and the center of the window opening horizontal frame, and the window switch and the window switch installed on the wall pillar side. The installed energy storage devices are connected by a polygonal horizontal axis,
Furthermore, a rope is suspended between the power accumulator and an operating device disposed at a location where it can be easily operated at hand. Therefore, the fenestration is the same operating device ( (The internal structure is not shown) When the release button that protrudes from the operating device is pressed, the rope that has been wound on the rope reel in the power storage device located above the operating device is automatically unwound. We will start the return, but
This unwinding action is achieved by winding the rope in an S-shape between a second reel that is fitted onto the cable reel shaft and integrated with the second reel, and another first reel that is fitted onto the end of the horizontal shaft. This is due to the restoring force (described later) of a known constant force spring. When the first reel rotates via the second reel due to the restoring force of the constant force spring, the horizontal shafts connected by universal joints simultaneously rotate the caterpillars in each window opener and decelerate the caterpillar gears. In order to do this, another chain wheel, which is integrally fitted to the shaft of the caterpillar gear, is rotated. Therefore, the irreversible chain that engages with the chain wheel is pushed forward from within each window opener, becomes a rigid rod-like body according to its characteristics, and protrudes the window edge, making it possible to open the window. In order to cope with unforeseen situations such as the weight difference due to the size of the window and wind pressure, this invention also uses an extension-biased shock absorber between both edges of each window and the vertical frame of the window opening to support the constant force spring. A well-known stay damper, which is a component, is attached to the system to ensure that the fenestration operates smoothly even in the unlikely event that the fenestration operation is disturbed (wind pressure, weight increase due to increased number of windows, frictional resistance of rotating parts). It's on.

In addition, the known constant force spring used in this invention is
Also called a constant force spring, it is tightly wound around the first reel in its original shape without fixing the end, and as per the regular usage, the other end is pulled out and fixed inside out to the body of the second reel (screwed). ), the cable is wound in an S-shape between the two reels and is wound as the cable reel rotates, but the torque to rotate the second reel in such a case depends on the characteristics of the constant force spring. Since the handle is always kept constant even when the handle is moved, manual rotation of the handle on the operating device does not result in overload, which is extremely labor-saving. Energy is stored to restore the length of the rope that has been pulled out from the first reel, so when the rope is released by pressing the release button,
Due to the restoring action of the constant force spring, the length wound on the second reel is returned to the first reel, so the first reel and the horizontal shaft are also rotated to push the irreversible chain forward and perform fenestration. .

[Closed window]

When the handle on the operator side is rotated in one direction, the rope that has been wound on the rope reel is wound around the winding drum (not shown) inside the operator, and the rope is restored to tight winding on the first reel. In order to wind up the constant force spring that was previously held on the second reel, the first reel reverses itself and pulls back the irreversible chain via the horizontal shaft and the caterpillar, thus closing the window. become.

In addition, when installing the device of this invention, if the opening angles of each window are all aligned, the irreversible chain will not naturally stretch like a cable, so there will be no gap between the window and the opening frame when the window is closed. It has been confirmed through careful experiments that this does not occur at all.

[Stopped midway]

When the stop button at the bottom of the operator is operated, a check mechanism acts to stop the take-up drum even when the window is open, thereby stopping the movement of the cable and at the same time stopping each reel in the power storage device and the linkage. The horizontal shaft, caterpillar, chain wheel, and other parts for opening and closing the window are all stopped, so the window stops halfway in an instant, and safety measures have been adopted in the operating device to prevent rapid reversal of the handle.

(Embodiment) An embodiment of this invention will be described based on the drawings. 1 is a window opener, in which a caterpillar 2 A chain wheel 4 with which an irreversible chain C engages is integrally fixed to the shaft of a caterpillar gear 3 that meshes with the caterpillar 2. A polygonal horizontal shaft 7 is connected to both ends of the shaft of the caterpillar 2 via a universal joint 6, and the end thereof is connected to the shaft of a cable reel 9 in a power storage device 8 disposed on a wall side column. The second integrally fitted
Near the upper part of the reel 10, the end of the constant force spring 12 is connected via a universal joint to the shaft end of the first reel 11 which is not fixed to the body but is tightly wound naturally. The end of the constant force spring 12 is pulled out from the first reel and fixed (screwed) upside down to the body of the second reel 10 that is integrated on the axis with the rope reel 9.
It is wound in an S-shape between both reels.

Therefore, when the constant force spring is tightly wound on the first reel, in addition to the distance that it is wound on the second reel (the distance required for fully opening the window), it must be wound once or twice. It is necessary to prevent it from coming off from the first reel.

A constant force spring 12 opens the window W of the cable 20 that is stretched between the cable reel 9 and a take-up drum (not shown) in another operating device 13 disposed below the wall side column. Since a sufficient restoring distance is required for this, the distance to be wound onto the second reel is measured and set in advance.

Reference numeral 5 in the figure indicates a known stay damper, which is attached to both side edges of the window and the edge of the opening frame, respectively, and buffers the restoring force of the constant force spring 12 in the force storage device 8. This serves to prevent frictional resistance from rotating parts. Reference numeral 14 represents an open button at the bottom of the operating device, 15 represents a stop button, and 16 represents a handle for manual operation.

(Effects of the invention) According to this invention, window opening and mid-stop can be performed safely and accurately by push button operation, and the distance between the window edge and window opening frame when fully closed is independent of the number of windows. This prevents wind and rain from entering the window, thereby maintaining the cooling and heating effect, and the caterpillar gear mechanism completely blocks pushback caused by gusts of wind or wind pressure during window opening, ensuring safe window opening. In addition, it can be easily installed on existing multiple windows, meets fire regulations, and is safe, quick, and easy to operate, which customers will appreciate.
This is an extremely practical idea that solves all of the previously unresolved problems such as low cost.
