Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a normal device for opening and closing a window (operating box for winding up a wire rope).

Conventionally, when operating the opening/closing device of a high smoke evacuation window using a wire rope using an external force, regulations have required a roadway device that can be operated manually and within easy reach.

However, the noise of the ratchet mechanism's pawls bouncing back and forth when the operating handle is rotated is annoying, and if you accidentally attempt fenestration while the handle is in place, the handle may come in contact with an object. However, it was extremely dangerous as it caused a shock due to the considerable torque.

This invention completely eliminates the above deficiencies and drawbacks,
In either case, when the drum is rotated by the handle operation to wind or unwind the wire rope, the ratchet mechanism does not generate any noise due to the claws bouncing back and forth, and the attachment axis may unexpectedly reverse while the handle is attached. The aim is to provide a noiseless and highly safe emergency device configured so that the handle does not operate under full heat even when the handle is heated.

Embodiments of the present invention will be described below with reference to illustrative drawings.

Winding up the wire rope for opening and closing windows (hereinafter referred to as rope W),
The normal device for unwinding consists of a box B and a lid C.
It is mainly installed on the side of the stile so that it can be easily operated manually within easy reach.

The operating shaft 1 has a polygonal columnar hole in its front end, and has a lid C and a case B.
A pin 4, which is fixed by a push screw 5 from the polygonal column hole side, is inserted into the middle part and protrudes beyond the operating shaft 1, and a protrusion having an inclined surface is provided on the rear side. The piece 6 is erected and is configured so that the vertical rod (to be described later) of the link mechanism is press-fitted to fully close and then raised to release the claw grip.

The slider 2 is a bowl-shaped cylindrical body that is slidably fitted on the outside via the operating shaft IK bullet 7, and a clutch 2C with a concave-convex shape equally divided on one outer peripheral edge and a concave-convex clutch 2C on the other inner peripheral wall. A serrated engaging portion 2 B f is formed with one side upright and the other side inclined, and is constantly pressed against the side wall of the lid body C by a bullet 7 .

A spur gear 3G is engraved on the outer periphery of the left and right flanges 3A protruding from the drum 3, and a corrugated bottom layer 3B is formed so that the cable W can be wound in an orderly manner. It is rotatably fitted onto each circular boss of the lid C and the box B and hung horizontally.

Further, at the first end on the bottom layer portion 3B side, another clutch 3C that can engage with the uneven clutch 2C on the slider 2 side is formed on the back wall thereof.

The spur gear 3G on the collar 3A of the drum 3 having such a configuration rotates at an increased speed via the intermediate gear 8 to control the force for opening the window. At the same time, a well-known roller clutch 11 that operates only when rotating in one direction is fitted onto the claw axle 12 which is pivotally supported below.
The cutter and replaceable teeth are always meshed with the wheel 10.

Further, the pawl axle 12 has a pawl 1 on the opposite side of the switching gear 10.
3 (commonly referred to as a ratchet wheel) is fixed, and the pawl rod 14 is the main part of the link mechanism IT (described later), which can perform multiple functions such as pawl engagement by the action of the protrusion 6 at the rear end of the operating shaft 1 and pawl release by opening. Nail 15? It is constructed so that the function of a non-return mechanism or ratchet engagement can be achieved as a relative part.

The link mechanism 1t is assembled around the operating shaft 1 and the ratchet wheel 13 near the bottom of the box B, and its operating system has the following complex functions.

That is, in detail, if the opening 16 protruding from the lid C is pushed forward in order to open the window, the opening 16 will be pushed into the step 24 of the case.
The pawl rod 14 is inserted into the shaft and is completely prevented from descending, and the pawl rod 14 is also tilted upward about the pivot 14A by the upward distance of the vertical rod 21, and the pawl rod 14 and the ratchet wheel 13 are disengaged from each other. .

Therefore, the gear transmission with the spur gear 3G carved on the collar 3A side of the drum 3 that meshes with the switching gear 10 via the roller clutch 11 fitted onto the pawl axle 12 of the ratchet wheel 13 is non-negative. As a result, the cable W that had been wound around the corrugated bottom layer 3B until then is reversed by the repulsive force of another energy (i.e., a stay damper or other spring) that is biased in the fenestration direction. (Left) In this case, the torque generated in the drum 3 increases in proportion to the degree of fenestration, so a well-known speed adjustment device is used. In this invention, a spur gear 3G disposed around the collar 3A of the drum 3 interlocks an intermediate gear 8 disposed above and a pinion shaft 9, and is attached by a braking device G (usually a circular center governor device) at the end of the shaft. Configured to control forces.

Next, regarding the operation of the link mechanism II- when closing the window, when the operating shaft 1 rotates once in the positive (right) direction by the rotation of the handle ■ fitted into the operating shaft 1, the shaft The protruding piece 6 erected at the rear is connected to the horizontal rod 22 and the support rod 2 of the link mechanism R.
5, the horizontal rods 22,
In order to move the support rod 25 to the right, the stepped portion 24 of the vertical rod 21
The horizontal rod 22, which had been inserted into the vertical rod to prevent its descent, separates (therefore, due to the pressure of the torsion spring 28 that presses the upper part of the vertical rod 21, the kick spring 29 that presses the claw rod 14 from above, etc. Because the rod 21 descends rapidly,
The pawl 15 of the pawl rod 14 strongly engages the pawl wheel 13 fixed on the small axle 12 to maintain a non-return mode (also referred to as ratchet engagement or pawl engagement).

In such a case, the support rod 2 with the horizontal rod 22 and the claw body 26
5 is interlocked and brought into contact with the upper part of the vertical rod 21, and when the operating shaft 1 is rotated frequently in the positive (right) direction, the claw engagement is held at a constant value and does not move even slightly. No noise from the nails bouncing occurs at all.

This means that when the operating shaft 1 rotates forward (rightward), the drum rotates in the same direction due to clutch engagement with the slider 2, but the mold that fixes the aforementioned mold wheel 13 that meshes with the spur gear 3G of the drum 3. Roller clutch 11 on axle 12
Since the switching gear 10, which is fitted externally through the
Since the type axle 12, which is the rotating body of the switching gear 10 that engages, is not driven to rotate by the unilateral action of the roller clutch 11,
Since the mold wheel fixed to the mold axle 12 is in a stationary state, it does not have any effect on the claw engagement, so when the rope is wound up by the rotation of the drum 3 (right), that is, when the window is closed. No claw noise will occur at all.

Next, a pin 4 penetrating through the center of the operating shaft 1 moves the slider 2, which is slidably fitted into the positive (right) rotation line of the operating shaft 1 via the bullet 7, backward, and the drum In detail, the clutch 3C on the inner surface of the clutch 3C and the clutch 2c2 of the slider 2 are configured to rotate the drum 3 in the same direction by engaging them, or to prevent the slider 2 from retreating when the drum 3 is turned in the opposite direction (left). A bowl-shaped cylindrical slider 2, which is slidably fitted onto the operating shaft 1 via a bullet 7, has an upright hanging wall on one side and a sawtooth-shaped engaging portion 2B on the other side. The pins 4, which are formed in an appropriate number and are divided into protrusions from the operating shaft 1, are normally located between the hanging wall and the slope of the engaging portion 2B, that is, on the valley side. When the operating shaft 1 is rotated forward (rightward), the pin 4 begins to slide on the slope of the engaging portion 2B, and the slider 2 is sequentially retreated, and when the pin 4 is located near the top of the slope, The slider 2 removes the pressure of the bullet 7 and retreats to the maximum, and at the same time, the clutch 2C formed on the outer peripheral edge side of the slider 2 engages with the clutch 3C formed on the back wall on the drum 3 side, rotating the drum 3. When the rotation stops, the clutch engaged by the restoring force of the bullet 7 is disengaged, and at the same time the pin 4 returns to the valley side.

If the operating shaft is rotated in the opposite direction (to the left) in such a state, the pin 4 will come into contact with the hanging wall of the engaging part 2B and the slider 2 will be rotated.
([-Even though they are interlocked in the same direction, the clutch engagement between the drum 3 and slider 2 has already been released, so the slider 2 only rotates idly.

Therefore, only when the operating shaft 1 rotates forward (rightward), the pin 4 moves the slider 2 backward and engages the clutch with the drum.
When the rotation is stopped, the slider 2 is separated from the clutch engagement, and when the rotation is reversed (to the left), the pin 4 interlocks the slider 2 but cannot interlock the drum.

This invention provides a great deal of convenience and safety to the consumer group due to the following features and effects obtained by the above-described configuration.

A. (When the window is closed) Even if the drum 3 for winding the cable W is rotated forward (rightward) by the handle operation, the claw mechanism is configured so that it does not operate in conjunction with the drum 3 for winding the cable W. No noise is generated.

・Therefore, the window can be closed by turning the handle quietly.

B. (When opening the window) The engagement of the pawl mechanism is released by the opening 16, and the pawl 15 of the pawl rod 14 and the model wheel 13 do not come into contact while the cable W is being fed out from the drum 3 while being controlled in speed. Because it is configured as follows, no noise is generated.

・Therefore, fenestration will be carried out quietly.

C0 (during operation) When rotating the handle fitted on the operating shaft 1, as soon as the forward (right) rotation is stopped, the clutch engagement between the slider 2 and the drum 3 on the operating shaft 1 is released and the clutch engages freely. Due to the configuration in which the nozzle is in the state of

・Therefore, in any case, including when opening a window, and when wearing shoes, there is no danger from the bounce 9 of the handle.

D. (When reversing) If the operating shaft 1 is rotated in the opposite direction (to the left) by operating the handle, the operating shaft 1 and slider 2 will simply rotate idly and will not move other members, so any unexpected accidents caused by the handle will be avoided. Does not occur.

・Therefore, closing the window is done by forward rotation using the handle, while opening the window is limited to button operation, so it is divided into individual independent functions, so there is no chance that visitors and shoes will confuse opening and closing windows. It doesn't happen.

E. (Button mechanism) The opening 16 press-fitted when the window is opened is automatically returned to its natural state by lowering the vertical rod 21 by moving the pawl 26 of the link mechanism 1t using the protruding piece 6 of the operation shaft l. Therefore, there is no need for a separate category for return.

- Therefore, it is convenient because the opening returns to its original position following the positive (rightward) rotation of the handle 1■.
