Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the swinging of outward-folding windows, etc., in which the lower edge of a shoji that opens and closes an opening in a window frame is pivotally supported on the window frame, and the window is opened by tilting it toward the outdoors. This invention relates to an opening/closing device for an opening/closing window, in which a rope is passed around a pulley supported by a window frame and a shoji, respectively, and by pulling the rope, the shoji closes the window against the bias in the direction of opening the window, and by letting it out, opens the window.

In particular, the present invention relates to a swinging window opening/closing device in which both the pulleys of the shoji and the window frame are hidden in the space between the shoji and the window frame when the window is closed.

Problems to be Solved by the Prior Art and the Invention In such a swinging window, one end edge of the shoji is pivotally supported on one end edge of the window frame, and is biased in the direction of opening the window by a telescopic stay or a torsion bar. , a pulley is arranged inside the other edge of the window frame and on the other edge of the shoji corresponding to the other edge at a distance from the other edge when the window is closed;
These pulleys are pivotally supported by shafts parallel to the support shafts of the shoji on supports that are freely swingably supported on the shoji and the window frame, respectively.
A rope is passed through these pair of pulleys, and by pulling in and letting out the rope, the shoji is swung in the direction of closing the window and opening the window. By tilting each pulley, each pulley always corresponds parallel to the rope that is tensioned at an oblique angle between the window frame and the shoji, allowing the rope to be pulled in and out smoothly, and to prevent the window from closing. Sometimes both pulleys are hidden by fitting within the space formed between the inside of the window frame and the outside of the shoji, but as the swing angle of the shoji increases, the shoji and the window frame The oblique angle of the rope to the window frame becomes large, especially when the shoji swings nearly 90'' to the window frame, the rope tensioned between the shoji and the window frame becomes Approximately 45
By forming an oblique angle of 45°, the pulley of the shoji is inclined at approximately 45° with respect to the edge of the shoji that supported it, and the Wli between the edge of the shoji and the center of swing of the pulley is If the distance is small, there is a risk that the rope tensioned between the shoji and the window frame will rub against the edge of the shoji that supports 31 tons on the closed window side. The center of swing of the pulley must be sufficiently spaced from the edge of the shoji, and to do this, the space between the edge of the shoji and the corresponding edge of the window frame when the window is closed must be had to be made larger, which had the disadvantage that the opening area of the window frame would become smaller.

Means for Solving the Problems As a means for solving the above-mentioned problems, the present invention provides a means for solving the above-mentioned problems by changing the position of the pivot point of the support that pivots the pulley of the shoji to the shoji on the fenestration side of the rope hanging groove of the pulley. The structure is such that the window is closer to the closed window than the center of the window.

Functions and Effects of the Invention The swinging opening/closing window opening/closing device of the present invention has the above configuration, and the distance from the swinging center of the pulley to the edge of the shoji on the window closing side is shortened, so even if the swinging angle is the same, the pulley The swing range of the edge on the closing side of the shoji becomes smaller, and even if the height of the pivot point of the support relative to the edge of the shoji is low, the shoji swings greatly and the slide 11 of the shoji moves toward the window. This prevents the rope tensioned between the shoji and the window frame from rubbing against the corner of the edge of the shoji on the closed window side when the shoji is tilted significantly against the edge of the frame. Because the height of the pivot point of the support that pivots the pulley relative to the edge of the shoji is low, the edge of the shoji that supported the pulley and the edge of the window frame that corresponds to this edge when the window is closed This has the effect of increasing the opening area of the window frame.

Embodiments Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings.

In the first embodiment shown in FIGS. 1 to 3, l is a window frame fitted into the wall of a building, and the lower edge of the shoji 2 that opens and closes the opening of this window frame is the lower edge of the window frame l. The shoji 2 is pivotably supported by the shoji 2 so as to be able to swing freely toward the outdoors, and is urged toward the outdoors, which is the window opening direction, by a biasing device (not shown) such as a telescopic stay installed between the shoji 2 and the window frame 1. At both left and right ends of the inner surface of the upper edge of the window frame l, slides 3.3 with rope hanging grooves 21 formed on the outer periphery are attached to the window frame by pins 4 parallel to the hinge axis of the shoji 2. Support 5 attached to 1 so as to be able to swing freely
On the other hand, on the upper end surface of the shoji 2 corresponding to the inner surface of the upper edge of the window frame 1, there are pulleys 6.6 corresponding to each of the 61 ton 3 of the shoji 2. The support 7a is supported between upper and lower support plates 8.8 which correspond to each other in parallel with an interval between them.
A pulley 6 with a rope hanging groove 20 formed on its outer periphery is supported by a shaft 9, and as shown in FIG. A guide surface 19 is formed, and support pieces 10 and 10 are provided on both left and right edges of the lower support plate 8 and protrude downward at approximately the center corresponding to the shaft 9. .10 are supported by pins 12 on brackets 11 fixed to the upper end surface of the shoji 2, respectively, so that the pulley 6 swings around the pins 12 and 12. J+ A wire rope 14 which is freely supported and whose one end is connected to the window frame l is stretched between the rope hanging grooves 21 and 20 of the frame wheels 3 and 6 of the - pair of the window frame 1 and the shoji 2. : The cable is routed along the upper edge of the frame 1, is turned downward by a turning pulley (not shown), and the other end is connected to a winding device 1'l installed at a nearby position on the wall. By winding the wire rope 14 with the winding device, the shoji 2 swings in the window closing direction against the biasing force in the window opening direction by the biasing device, and the window is closed. 14, the shoji 2 is swung toward the outdoors by the biasing force of the biasing device, and the window is opened.

The swing center of the support 7a that pivotally supports the pulley 6 of the obstacle T-2 is
As shown in FIG. 1, when the pulley 6 is in a horizontal position with the window closed, the rope hanging groove 2 on the outdoor side (opening side)
As the shoji 2 swings toward the outdoors, the pulley 6 moves its outdoor side away from the upper end surface of the shoji 2. Moreover, the indoor side of the shoji 2 is tilted closer to the upper end surface of the shoji 2, and as a result, the shoji 2 is tilted closer to the upper end surface of the shoji 2 than the A-A line, compared to the conventional case where the swing center is on the outdoor side. The approach distance of the pulley 6 to the upper edge of the indoor shoji 2 when swung by the same angle is small, and as a result, the support 7a
Even if the height of the middle + 1 + support position relative to the upper edge of the shoji 2 is small, as shown in Figure 2, the shoji 2 will move 90 degrees to the outdoor side.
By swinging, the wire rope 14 tensioned between the shoji 2 and the window frame 1 at an oblique angle of approximately 45° is prevented from hitting the indoor side edge of the upper end surface of the shoji 2, As shown in FIG. 1, it is possible to reduce the corresponding distance X between the upper end surface of the shoji 2 and the inner surface of the upper edge of the window frame 1, and therefore, the opening area of the window frame 1 can be increased.

Note that a clockwise moment about the pin 12 acts on the support 7a due to the tension of the wire rope 14 stretched between the shoji 2 and the window frame 1, and the support 7a tries to rotate clockwise. , as shown in FIGS. 2 and 3, the guide surface 19 at the edge of the upper support plate 8 of the support 7a engages with the wire rope 14 tensioned between the window frame l and the shoji 2. This prevents the wire rope 14 from being tilted more than a predetermined amount. However, by making the rope hanging groove 20 of the pulley 6 sufficiently deep, the side surface of the rope hanging groove 20 hits the wire rope 14 and the support 7
In this case, it is not necessary to form the guide surface 19 on the support plate 8 of the support 7a.

FIG. 4.5 shows a second embodiment, in which the support 7b includes a support piece 15.1 for pivotally supporting the bracket 11 of the shoji 2.
A support hole 16 is formed in each support piece 15 at a height corresponding to the center of the pulley 6 in the thickness direction. As shown in FIG. 5, it is supported on the bracket 11 by a pin 17 fitted into the support hole 16, and in this support 7b, the pulley 6 swings around an axis passing through its center line. , wire rope 1 tensioned between shoji 2 and window frame l
The clockwise moment acting on the support 7b due to the tension of 4 is smaller than that of the support 7a, and therefore the inclination of the support 7b with respect to the wire rope 14 can be suppressed to a small angle.

In this embodiment, the positions of the pivot points of the supports 7a and 7b are set to correspond to the center of the pulley 6 in the horizontal direction, as shown in FIGS. 1 and 5. However, it is not necessary to do so, and it is sufficient that the position is on the indoor side (closed window side) of the line A-A passing through the center of the rope hanging groove 20 on the outdoor side (closed window side) of the pulley 6.

A third embodiment of the present invention shown in FIGS. 6 to 8 is a shoji 2
A protrusion 32 is formed at the center of the upper surface of the bracket 31 on the inside of J4 (closed window side), which is fixed to the front edge of the upper edge of the window frame l side (closed window side) with a screw 30.

The bearing portions 37 and 37 of the support 36 are fitted to the protrusions on both sides of the spring pin 34, which are press-fitted into the attachment holes 33 transparently provided in the protrusion 32, through the bushings 35.
is supported to freely swing vertically around a spring pin 34. This support 36 has a pair of upper and lower support plates 38.38 that are parallel to each other formed integrally with the rear part of a bearing part 37.37, and a rivet 39 that is crimped through the center of the upper and lower support plates 38.38. As a result, the pulley 6 having a rope hanging groove 20 formed on its outer periphery is rotatably supported, and upper and lower support plates 3 are provided on both sides of the bearing portion 37.
Upper and lower guide pieces 42.42 connected to 8.38 are formed with a gap 43 in between, and the upper support tl! Five claw pieces 45 protruding from the outer periphery of the presser plate 44 collinear with the rivets 39 on the upper surface of 238 are bent downward to connect the upper and lower rear half portions between the upper and lower support plates 38 and 38. It spans the diagonally rear part between the guide pieces 42 and 420.

Further, a protrusion 46 is formed on the outer periphery of the front end of the bearing portion 37.
The swing angle with respect to the bracket 31 is restricted to 40°.

Furthermore, the front sides of the guide pieces 42, 42 on both sides of the support 36 are shaved off a little more than the rear sides to form relief parts 48. In this embodiment, the rope hanging grooves 21 and 20 of the pulley 3 attached to the window frame 1 side and the pulley 6 attached to the shoji 2 side are
As shown in FIG.
The wire is routed through the gap 43 between the lower guide pieces 42 and 42 on both sides of the wire lobes 14, and is surrounded by claw pieces 45 so as not to come off. When the shoji 2 is tilted toward the outdoors and the window is opened,
Wire lobes 14 with guide pieces 42 and 42 tensioned diagonally
By engaging with the spring pin 34, the support 36
oscillates around.

The shoji 2 is maintained in a position substantially parallel to the wire lobe 14 so as not to tilt more than a predetermined level, and the shoji 2 is fitted into the window frame l to close the window, as shown by the solid line in FIGS. 7 and 8. When this happens, there is a relief part 4 on the front side of the guide piece 42 of the support 36.
8 is formed so that it does not interfere with the pulley 3 on the window frame l side. In this embodiment, the spring pin 34, which is the center of swing of the support 36 of the pulley 6 on the shoji 2 side, is located at the end of the support 36 on the window frame 1 side (closed window side). Since the shoji 2 is located on the side of the window frame 1 (closed window side) at the position X★, the corresponding interval It has the advantage that it can be made smaller and the glass area of the shoji 2 can be maximized.
