Description

Detailed Description of the Invention: Industrial Field of Application The present invention relates to an outward folding window in which the lower edge of a window plate is hinged to a window frame and folded toward the outdoors, or a window in which the upper edge of a window plate is attached to a window frame. In swing-opening windows such as projecting windows that are hinged to the frame and protrude outward to open, a wire is passed through pulleys that are pivoted on the window frame and the window board, respectively, and by pulling the wire, the window board is moved in the direction of the window opening. The opening/closing wire, which closes the window against the force of the window and opens the window by drawing it out, may fit into the groove of the pulley from an oblique direction when opening the window, causing the support shaft of the pulley to be pried. The present invention relates to an opening/closing wire guide device that prevents the wire from rubbing against the outer periphery of a pulley, the edge of a window plate or window frame, or from coming off the pulley.

Problems to be Solved by the Prior Art and the Invention Swinging windows such as outward folding windows or projecting windows are made by hinged one edge of the window board to one edge of the window frame and opening with a telescopic stay or torsion bar. The wire is biased toward the window, and wires are stretched between a pair of grooved sliding rivers that are rotatably supported on the other edge of the window panel and the corresponding other edge of the window frame, and the window panel is pulled in and out. The wire is swung in the direction of closing and opening the window, but as the opening of the window plate increases, the wire is tensioned diagonally to the window frame and window plate, so the pulley If the wire is supported against the window frame or window plate so that it cannot tilt, the part of the wire that is tensioned away from each pulley and toward the corresponding pulley will fit into the groove of the pulley from an oblique direction. . Therefore, if the support shaft of the pulley is pried, the wire rubs against the outer periphery of the pulley, the edge of the window board or window frame, or the angle is large, the wire may come off the pulley. To prevent this, conventionally, a support supporting both pulleys is supported with an axis perpendicular to the support axis of the pulleys so that it can tilt freely relative to the window frame or window plate, so that the pulleys always follow the wire. It was designed to change its posture by pointing in the direction of the tension, but it required a large space to mount the pulleys on both the window frame and the window plate so that they could swing freely, especially on the side where the window plate was thinner. This is difficult, and the protruding direction of the wire changes depending on the opening degree of the window plate, so it is necessary to form a large wire insertion groove in the window frame and window plate.
There was a drawback that the waterproof performance decreased when the window was closed.

Means for Solving the Problems The present invention, as a means for solving the above-mentioned problems, biases a window plate whose one end edge is hinged to one end edge of the window frame in the window opening direction,
The window plate is swung in the window closing direction and the window opening direction by pulling in and letting out a wire that is stretched over a grooved pulley pivotally supported on the other edge of the window frame and the other edge of the window plate. In the swinging opening/closing window, a pulley of the window plate is supported on the window plate so as not to tilt, and a wire is attached near the pulley to move away from the pulley when the window plate is open. The structure is such that a guide roller is pivotally supported so as to touch and roll a portion to be tensioned obliquely to gradually change the direction of tension toward the corresponding pulley.

Functions and Effects The wire guiding device for opening and closing a swinging opening/closing window of the present invention has the above-mentioned configuration, and the wire that is tensioned diagonally with respect to the pulley fixed to the window frame in a manner that it cannot be tilted is brought into contact with the guide roller. Because it can be inserted straight into the groove of the pulley, there is no possibility that the support shaft of the pulley will be pried, the wire will rub against the outer periphery of the pulley, the edge of the window plate or window frame, or the wire will come off the pulley. Moreover, since the tension direction of the part of the wire that comes into contact with the guide roller is gradually changed, there is no risk of large bending stress being generated in that part, and the guide roller is able to prevent the wire from being drawn in. In addition, since the wire contacts and rolls during feeding, the wire is prevented from being worn out due to contact with the guide roller, which has the effect of preventing the wire from breaking.

EXAMPLE Hereinafter, an example in which the present invention is applied to an outward folding window will be described based on the accompanying drawings.

In the figure, l is a window frame fitted into the wall surface, the lower edge of the window plate 2 is supported by a hinge 3, and there is elasticity between the left and right edges of the window plate 2 and the window frame 1, respectively. A torsion bar 5, which is a bent steel rod having Horizontal shafts 8 are supported by brackets 7 near both ends of the lower surface, and pulleys 12 are supported perpendicularly to the horizontal shafts 8 by supports 10 supported by the horizontal shafts 8 so as to be able to swing freely in the vertical direction. It is rotatably supported by a shaft 14, and on the other hand, supports 15 are fixed to the upper surface of the upper edge of the window plate 2 at positions facing inside of both pulleys 12 and 12 of the window frame 1. Pulleys 17 are rotatably supported by support shafts 16 fixed to the fixtures 15, and a wire 19 is routed below the upper edge of the window frame 1 along this. The wire 1 is stretched between a pair of pulleys 12 and 17 near both ends, and one end is fixed to the window frame 1 while the other end is connected to a winding drum of an operation box (not shown).
7 on the winding drum and pulling it in, the window plate 2
is swung indoors against the biasing force of the torsion bar 5, the window is closed as shown by the solid line in FIGS. 1 and 2, and the wire 17 is opened by unlocking the winding drum. The window board 2 is unwound from the take-up drum and swung toward the outdoors by the urging force of the torsion bar 5 to open the window.
The swinging angle of the window plate 2 at this time is regulated by a stopper 18 installed between the side edge of the temporary window 2 and the window frame 1, and as shown by the chain line in FIG. Although the plate 2 is designed to stop at a predetermined swing angle, in this embodiment, on both sides of the pulleys 17 and 17 of the window plate 2,
A support shaft 20 parallel to the upper edge of the window plate 2 is supported by a bracket 21 on the indoor side of each pulley 17, and each of these support shafts 2o has a tapered surface 23 formed on both sides of a large diameter portion 22. A guide roller 25 and a collar 26 having a smaller diameter than the large diameter portion 22 are fitted so as to rotate freely, and the large diameter portion 22 of each guide roller 25 has a fenestration as shown by the chain line in FIG. In this state, the wire 19 is fed out between the pulleys 12 and 17 and is tensioned. It corresponds to

Next, the operation of this embodiment will be explained.

When the window is opened, the wire 19 let out between the pulleys 12 and 17 of the window frame 1 and the window plate 2 is tensioned in an oblique position, and the pulley 12 of the window frame 1 is supported so that it can tilt freely.
The groove 1 on the outer periphery of the pulley 12 is tilted along the tension direction of the pulley 12.
Whereas the wire 19 is inserted straight into 2a,
Since the pulley 17 of the window plate 2 cannot be tilted, its groove 1
The wire 19 takes an oblique position with respect to the guide roller 25 when the window plate 2 swings a little from the closed state. The wire 19 slides on the tapered surface 23 and rests on the upper surface of the large-diameter portion 22, so that the wire 19 is separated from the pulley 17 of the window frame 1, as shown by chain lines in FIGS. 1 and 2. The wire 19 is inserted straight into the groove 17a of the pulley 17 by curving the upper surface of the large diameter portion 22 of the guide roller 25 in the same way as the portion facing the pulley 12. Since the inclination angle is gradually changed on the upper surface of the diameter portion 22, there is no risk of large bending stress being generated, and since the guide roller 25 comes into contact with the wire 19 when the window plate 2 swings, the outer periphery of the wire 19 In addition to avoiding damage to the window, there is no risk of loss of operating force for opening and closing the window.

Note that when the window plate 2, which swings in the window opening direction as the wire 19 is fed out, is held in the fully open position with its swing being restricted by the stopper 18, as shown by the chain line in FIG. The tension may be lost and the wire 1 may loosen from the large diameter portion 22 of the guide roller 25.
9 comes off and rests on the collar 23, but in this state, when the wire 19 is pulled in by the winding drum to open the window, the wire 19 becomes tense and the wire 19 rests on the collar 23. The hanging portion slides on the tapered surface 23 of the guide roller 25 and rides on the upper surface of the large diameter portion 22.
