Description

TECHNICAL FIELD The present invention relates to a rope operation device (wire rope winding machine) used when opening and closing a window.

(Prior Art) Conventionally, the rope operating device in the opening / closing device of the smoke exhaust window is required to be installed within a reach of human operation by law. Most of the conventional techniques are to wind the wire rope with a handle manually when the window is closed, and to unwind it with a stay-damping open damper when the window is opened, which inevitably repeats starting and stopping with a ratchet mechanism. However, the bounce noise of the nails becomes annoying, and when it shifts to the open window with the handle attached, there is a danger that the rotation range of the handle will become sharp due to the sudden generation of acceleration torque, so in order to eliminate these drawbacks. Japanese Patent Application No. 58-152141 (a guide device for opening and closing a window), which was previously filed by the same person as the inventor of the present application, was provided, but regrettable that it cannot be stopped at any place when the window is opened. Heaven If the window is opened slightly for ventilation under other conditions, it will be fully opened, so the handle must be rotated to move the window to the desired location, which is labor-saving and labor-intensive, which is inconvenient to use. .

(Problems to be solved by the invention) Since the smoke exhaust window opening / closing device is in principle manually operated as described above, the ratchet mechanism is inevitable as long as it is incorporated in the structure, so the bounce noise of the claw is completely removed. With the feature of the prior art by the same person as the inventor of the present application that the impact by the mounting handle does not occur at all, it also has a step forward function that safely and surely stops at any position at any position even in the window opening process. The early realization of such a rope operation device has become a much-needed problem in the domestic and overseas demand layers.

(Purpose of the invention) Completely eliminates rattling claw bouncing noise that is forcedly generated in the wire rope winder to maintain the silence around the room, no recoil of the operation handle occurs, and it can be turned up and down freely. With a safety structure that can be folded and stored with, and a button device that allows any person to easily operate arbitrary stop and open / close switching in the window opening process, which has been regarded as a problem in the past, is a labor saving rope operation. The purpose is to provide the device to the market at low cost.

(Means for Solving Problems) A rope operating device for opening and closing a window according to the present invention is provided on a peripheral wall of a stage shaft in which a large gear at the end of a reduction gear train interlocking with a well-known handle shaft capable of 180-degree reversal is inserted. When each knob that bulges toward the relative side slides on the slope in the arcuate groove that is carved on the relative side on one side of the collar and abuts the small wall, the kick spring exerts an urging force on the base side. The saw teeth formed at the end of the slidable clutch body straddling the band on the intermediate body that moves forward in the same direction as the step shaft and rotates in the same direction as the saw teeth that rotate in the same direction when engaged Claw that engages / disengages with a ratchet wheel with a one-way clutch that is interlocked with the drum only when it rotates counterclockwise inside the drum gear in the speed increasing gear train that is lined up from another clutch gear in the section to the governor. Below the reset body with the member pivotally attached to the tip, it can be pivoted to a link pivotally attached by another bullet A window-opening push button in which the L-shaped link connected to is tilted on the inclined surface of the slider, and a stop button for closing the window that tilts the reset body with a hook-shaped lever rod are also included. It is characterized in that it is arranged in a more protruding shape.

(Operation) [Opening window] In Fig. 5, among the plurality of buttons protruding from the cover of the box, when the push button with a "push" mark and protruding further higher is pushed by hand, the L-shaped button shaft is , The lower part of the slider is loosely inserted in the groove of the box body and the upper part is loosely fitted in the hole of the table, so that the inclined surface below the slider abuts L
The foot of the L-shaped link is tilted (approximately 45 degrees), so that the L-shaped link and another reset body are pivotally connected in advance by the link, so that the extension spring is extended and one side of the L-shaped link is extended. Since the link floats in a mountain shape, the link pulls the reset body from the vertical side in the direction of the L-shaped link, so that the reset body tilts (rotates right) about the upper pivot as a fulcrum. In such a case, the claw member engaged with the tooth portion of the ratchet wheel is separated by the tilting of the reset body, and the claw engagement is completely disengaged, so that the wire winding drum can be rotated (right). The opening of the window starts due to the extension of the stay damper (ammo) that constantly biases the window toward the open side.
Therefore, the wire, which is suspended from the window to the drum and wound in multiple layers, is pulled out from the drum while the speed is controlled until the window stops fully opening, and the window opening is performed smoothly and without noise.

[Window closing] In Fig. 6, when the stop button with the "stop" mark protruding from the cover of the box body is pressed and pressed, the lower end of the stop button presses the diagonal piece of the lever rod. Therefore, the lever rod is tilted and displaced in the left rotation direction (arrow direction) about the pivot as a fulcrum. Therefore, the guide pin of the reset body tilted by the interlocking of the L-shaped link and the link by the push button operation at the time of opening the slider side. The foot piece of the lever rod that was pulled to is tilted in a substantially vertical direction, and the reset body is also tilted counterclockwise by using the upper pivot as a fulcrum and displaced in a substantially vertical direction. Since the claw member pivotally attached to the side meshes with the claw wheel, the drum gear fitted with the known one-way clutch that is adapted to interlock only when the claw wheel rotates to the left cannot rotate to the right at all. Inevitably it will be impossible to open the window, and When the dollar is rotated to the clockwise (positive) rotation side, the spur gear of the handle shaft interlocks with the right rotation of the large gear via the intermediate gear, and on the relative side of the stage shaft peripheral wall where the large gear is inserted. As the large gear rotates to the right, the protruding knob rides on the slope from the valley in the arcuate groove of the clutch body and contacts the small wall at the end of the slope, and the step shaft integrated with the knob advances the clutch body. When the gear teeth rotate to the right, the sawteeth at the end of the clutch body mesh with the sawteeth of another clutch gear that is rotatably fitted to the stage shaft to rotate the adjacent drum gear counterclockwise and to the speed governor. Interlock all speed increasing gear trains. Therefore, since the penetrating wall side of the box is previously provided with an insertion hole so that the rope moves on the left side of the drum, the rope (wire) is successively wound from the left side of the drum as the drum gear rotates counterclockwise. It is turned and the window is closed smoothly. If the handle slightly swings in the opposite direction when the clockwise rotation of the handle is stopped when the window is closed, the above meshing is caused by the restoring action of the kick spring that abuts on the collar including the band spanned by the clutch body. Even if is released, the drum side is in a state in which it can only rotate counterclockwise until it gets tired (claw engagement), so that it does not open the window, so the button operation is reliable.

[Stop on the way] In FIG. 7, when the stop button is arbitrarily pressed by the push button during the window opening, as described in detail in the section of the window closing, the resetting body is tilted and displaced along with the tilting of the lever rod. Further, since the right rotation of the drum gear is stopped by the meshing of the claw member and the claw wheel, the forward movement of the wire in the window direction, that is, the rewinding motion is stopped, so that the opening window is stopped at this point. After that, the window can be closed by rotating the handle to the right or the window can be opened arbitrarily by operating another push button.

(Embodiment) FIG. 1 is a front view of a handle operation box using an embodiment of the present invention as a rope operation device for opening and closing windows. A plurality of buttons protruding in parallel on one side of the cover 2 that covers the box 1 are engraved with push and stop marks, respectively, and the protruding states (high and low) of both are obvious, and the other side is wound. The handle 3 for taking is the same as the folding handle for operating the well-known tape measure.
It can be inverted at 0 degrees and can be stored along the side wall 4 of the body 1.

Next, the internal structure is shown in FIG. 2 to FIG. 9. Specifically, the base 5 is fitted to both side walls 4 and 4 standing on the box 1, and the pedestal 6 is arranged at a constant interval. The spur gear 7 for the handle 3 and the pivot 3 is attached at approximately the center of the base 5, which is attached.
Is spun between the small base 6 and the spur gear 7 and the split groove 9 at the shaft end.
A T-shaped piece 8 is pivotally attached to the
A root side of the handle 3 is pivotally attached to the handle 10, and a handle H is rotatably provided on the opposite side of the handle 10 so that the handle can be inverted and bent so as not to be bulky on the upper surface of the box 1 when not in use.

Further, the spur gear 7 for the handle pivot shaft decelerates and rotates the large gear 12 in the same direction through the intermediate gear 11, and when the large gear is tightly interlocked, the step shaft 13 has a peripheral wall as shown in FIG. The knobs 14, 14 are integrally bulged on the relative side of the stepped shaft 13, and the troughs in arcuate grooves 17, 17 formed in the collar 16 of another clutch body 15 slidably fitted on the stage shaft 13 When riding on the slope 19 from the side 18 and abutting on the small wall 20 at the end of the slope, the clutch body 15 moves to the large gear 12
, And the saw teeth 21 at the end mesh with the saw teeth 22A of another clutch gear 22 on the stage shaft 13, and as a result, the rotation of the large gear and the clutch gear is the same due to the right rotation of the handle. I will follow the direction.

The clutch gear 22 is a small gear of the speed governor 25 at the end of the gear train while the drum gear 23 that meshes with the adjacent gear is rotated in the reverse direction (left).
26 is rotated at an increased speed through the intermediate gear 24, and the rope 27 suspended from the window W is inserted through the small hole 28 formed on the side wall 4 of the box 1 on the left side when viewed from the base 5 side. The rope 27 is wound around the body portion 29 of the drum gear 23, and the rope 27 is wound from the left side of the body portion 29 at the time of closing the window in which the drum gear rotates left by the clockwise rotation of the handle.

Next, of the plurality of buttons projecting to one side of the box 1, the push button 30 projecting one step higher and fitted with the stop ring 31 has a "push" mark on the upper surface of the end, and the base 5 has a T-shape. It is loosely inserted in a button stand 32 placed in a block shape, but a screw pin 34 projects from the side of the button stand 32 into a key groove 33 formed on the axial surface of the push button 30 and another stop button (described later) Similarly to the above, the character of the "push" mark of the push button is prevented from being displaced to the left and right, and the block 35 projects horizontally at the lower end of the push button, and the shape of the push button 30 is L-shaped.

Therefore, when the push button is pushed down, the end portion of the block pushes down the top side of the slider 36 projecting from another base 5 and lowers it, but the slider has a circular upper portion and is loosely inserted into the round hole of the base. , The other has a short cross section and is loosely fitted in the groove on the bottom of the box 1, and a slope 37 is formed below the leg 39 of the L-shaped link 38 pivotally attached to the bottom of the box as it descends. Since it has a function of tilting in the counterclockwise rotation direction by touching the
The lateral piece 40 of the shaped link tilts upward to extend the pulling spring 41 while simultaneously pulling up another link 42 pivotally attached to each other, so that both of them are abutted from the left and right to form a mountain shape in which the center is lifted.

In such a case, the reset body 43 pivotally attached to the link 42 tilts so as to be pulled in the right rotation direction with the upper pivot support portion 44 as a fulcrum, and the claw member 45 pivotally attached to the tip side of the reset body 43 is connected to the claw wheel 50. This claw member that disengages the teeth of and completely separates
The leg 46 of 45 is always elastically pressed against the stop pin 47 by a torsion spring 48 attached to the pivot 44, and even if the claw member tilts to the right, it immediately returns elastically until it contacts the stop pin 47. It is structured like this.

Therefore, when the pawl member 45 separates from the pawl wheel 50, the speed reduction gear train on the handle side does not rotate, and the rope 27 wound around the drum gear 23 extends the stay damper (not shown) attached to the window side. Along with this, the window is smoothly opened because it is pulled out from the body of the drum gear at a controlled speed until the window is fully opened. In such a case, the hanging piece 52 of the approximately two-step L-shaped lever rod 51 loosely fitted to the guide pin 49 provided upright on the lower end of the reset body 43.
Is tilted to the right in Fig. 7, and at the same time the upper slant piece 53 is also pressed.
32 Since the tip portion of the oblique piece 53 approaches the lower end of another stop button 55 because it tilts in the clockwise direction with the pivot portion 54 provided at the lower end as a fulcrum, pressing of the stop button is speeded up. Become.

Next, if the stop button 55 is manually operated, the spring 56 is compressed and lowered, and the inclined piece 53 of the lever rod 51 is pushed down near the lower surface of the button base 32, so that the hanging piece 52 tilts substantially vertically. At the same time, the reset body 43 is also vertically pivoted through the guide pin 49.
Since the claw member 45 pivotally mounted on the fulcrum 44 as a fulcrum and the claw member 45 pivotally provided at the tip of the reset body 43 meshes with the claw wheel 50, the claw wheel can only rotate counterclockwise. Therefore, the clockwise rotation of the handle causes the drum to rotate as described above. The gear rotates counterclockwise 27
The window is smoothly closed while winding the coil, but in such a case, the L-shaped link 38 and the link 42 are arranged so that they are substantially aligned with each other.
Towed by 41.

The claw wheel 50 inserted into the drum gear 23 is provided with a special clutch metal (commonly known as a one-way clutch) that can only rotate counterclockwise, so that the claw member 45 always rotates in the engagement releasing direction. ing.

Further, a band 57 for pressure contact is laid on the collar 16 of the clutch body 15 at an intermediate body portion with the saw teeth 21 and pulled downward by a tension spring 58, and the collar 16 has a long foot end portion of a kick spring 60. Are pressed against each other, and both are urged so that the clutch gear 22 and the saw teeth 22A and 21 of the clutch body 15 are constantly separated from each other.

(Effect of the Invention) According to the present invention, the rattling noise caused by the opening and closing operation of the window, the claw noise caused by the ratchet mechanism, the case where the door is stopped halfway as well as the opening and closing, the collision accident due to the handle attached does not occur at all, and the handle While there is a switching button for opening and closing near the turning range,
Since the buttons can be operated without any anxiety, special and troublesome operations are unnecessary, and it is possible to safely and swiftly achieve the operation of opening and closing windows, and the problems that have been a long-standing problem have been solved more safely and securely. It is something that has come to be.
