2. Description of the Related Art Conventionally, in a double pulley device for opening and closing a window, one fixed pulley is disposed on each of the left and right sides on the window opening frame side, and at the upper side of the window side, substantially at the center position between the left and right fixed pulleys. The former provided with a single moving pulley and the latter provided with a plurality of moving pulleys and provided near the left and right constant pulleys were provided, but in the former case, the rope was substantially V-shaped along the groove of the moving pulley. To be connected to each fixed pulley on the frame side, so that the rope does not abut the ridge on the upper side of the window when opening the window, for example, use a cylindrical surface that is not merely a curved guide member but has a significant anti-friction effect. 62-180179 in which two rollers each having two independent rollers are disposed in front of and right and left of the moving pulley.
However, the pulley device disclosed in Japanese Patent Application Laid-Open Publication No. H10-209686 is provided, but after all, each roller externally fitted to one fixed shaft is pressed by the shaft as a result of the rollers being pressed by the V-shaped movement of the rope. Since the directions of the generated torques are different from each other, the smooth rotation of the roller is likely to be hindered by an unexpected load generation in the bearing portion or distortion of the shaft itself due to a strong torsional action applied to the shaft. On the other hand, in the latter case, the rope is hung from the fixed pulley to the moving pulley, so that the contact between the rope and the upper corner of the window side is avoided by a single antifriction member. Are completely different and have no relation to the present invention.

[0003]

[Problem to be Solved by the Invention] When the window is opened and closed by the double pulley device, the rope is hung from one fixed pulley (the window opening frame side) to the window-side movable pulley only when there is only one moving pulley on the window side. Since it is connected to the other constant pulley in a substantially V-shape, it is necessary to install rollers and pulleys as antifriction members so that the rope does not directly contact the horn on the upper side of the window at two places. ,
In the conventional technology, the pressure contact between the rope and the roller pressurizes the shaft, and torque is simultaneously generated in the forward and reverse directions with respect to the shaft. The narrow wing was impossible. Therefore, there is a need in the art for a new cable guiding means that can solve the above bad conditions and can be provided at low cost.

SUMMARY OF THE INVENTION A pulley device with a guide member for a window opening / closing cable according to the present invention is hung on a movable pulley pivotally attached to the upper side of a rotary window hinged to a window opening frame. A plurality of rotators slidingly contacting the rope are interlocked in a relative direction by meshing, and the reciprocating movement of the rope is smoothed.

[0005]

[Operation] The pulley device with a guide member used in the present invention works effectively only with a single moving pulley for one window when attached to the upper side of the window, but is not effective for use with a plurality of moving pulleys. It will be described in detail assuming that there is no such information. When the rope is moved by a winch or a handlebar with a handle for winding and unwinding the rope for opening and closing the window, the rope connected to both the fixed pulleys (window opening frame side) via the moving pulley (window side). Is divided into a side that enters the groove of the movable pulley and a side that exits from the groove of the movable pulley. In order to cope with the friction of different movements of the rope, a rotating body with a plurality of teeth is adopted, so that the rotating body is caused by frictional force generated by pressure contact between the rotating body and the rope entering the groove of the moving pulley. When rotating toward the moving pulley, the tooth portion at the end is forcibly linked with the tooth portion on the other rotating body in the opposite direction, that is, in the direction away from the moving pulley, so that the rope that advances from the moving pulley and the advancement Is guided by pressure contact with a rotating body that is forcibly linked in It is clear from experiments that the degree of contact between the moving rope and the rotating body is much smoother than the effect of the conventional technology in which the rotating body is simply pressed against the rope and slides on the shaft. It has become. Therefore,
Even if the direction of movement of the rope is opposite to the above, only the rotation direction is changed by the interlocking of the relative directions of the plurality of rotating bodies, and there is no slight effect on the smooth movement of the rope.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. The single moving pulley 1 according to the present invention is an essential member of the double pulley device for opening and closing the window, and its mounting location is the rotation window W hinged to the window opening frame F as shown in FIG. 3 and FIG. It is pivotally attached to an arbitrary position on the upper side so as to be tiltable. On the other hand, the fixed pulley is pivotally attached to the window opening frame F side to the left and right of the moving pulley 1 at substantially equal intervals so as to be tiltable, and a pulley (not shown) is opened from an operation box (not shown) for opening and closing the window. Rope 10 bridged through
From the first fixed pulley P ₁ through the moving pulley 1 to the next fixed pulley P
₂ is hung in a V-shape, but when the fenestration angle α increases, the V-shaped included angle β of the rope straddling the moving pulley 1 on the other hand decreases. Then the movable pulley 1 is tiltably hinged together embracing member 2 to the upper side W ₁ side mount plate 3 erected on the window W. The holding member 2 is formed in a clip shape on the side surface as shown in the second illustration, and the upper side has a lateral width close to the diameter of the pulley 1, but the lower side has a lateral width substantially equal to the lateral width of the mounting base plate 3. The left and right portions are extended to the same position, and both ends are bent downward to form left-right symmetrical vertical pieces 2A. A rotating body 4 having a tooth portion 5 engraved on another end is rotatably fitted to the plurality of stop shafts 6 and 6 fixed to the hanging piece 2A. Since the rotating bodies 4 and 4 have different rotation directions in the relative direction depending on the meshing, the ropes 10 moving in different directions with the moving pulley 1 as a boundary can be smoothly guided. The dripping piece 2
The interval between the stop shafts 6 and 6 fixed to A is slightly longer than the pitch circle of the tooth portion 5 in the rotating body 4, and it is important to set an appropriate clearance so that play of meshing is small. In addition, if the lateral movement of the rotating body 4 is not prevented, if the tip side of the other tooth part 5 rides on the curved surface from the bottom surface of the one tooth part 5 to the outer peripheral surface, a brake is generated between the rotating bodies 4 to rotate. For this reason, for example, as shown in FIG. 1, the stopper 7 is made to protrude from the lower side end of the holding member 2, and the stopper pipe 8 is loosely fitted to the stop shaft on the other rotating body side.
Both lateral movements of the rotating body can be prevented. If it is not desired to use the stopper, the pipe, or the like, the swelling piece is formed by hitting the stop shaft 6 side in advance at a position near the tip of the rotating body tooth portion, so that the lateral movement of the rotating body 4 is prevented. It is possible, but these means are practical design items until they get tired, and their adoption is free.

[0007]

According to the present invention, when a single movable pulley is provided on the window side in the double pulley device for opening and closing a window, the ropes on the side entering the movable pulley and the one exiting from the other movable pulley are one cable. Although it is a book, the moving direction will be different, but since the plurality of rotating bodies that press against the rope rotate in the relative direction due to meshing, the movement of the rope will be guided very smoothly, and labor saving of opening and closing the window will be achieved. Can be achieved.
