Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a window opening adjuster used for a vertical axis rotating window or the like in which a shoji rotates along a horizontal direction around a vertical (vertical) axis. In this specification, the swing system opening / closing window is referred to as an opening window, and typically includes an outer opening window, an inner opening window, a vertical axis rotation window, and the like, and the opening angle of the shoji in the opening window is referred to as an opening. Shall.
[0002]
[Prior art]
In general, the opening window uses an opening setting device that fixes the opening at intervals of several tens of degrees below the shoji to ensure the ventilation rate and safety. By the way, if the shoji is damaged by a gust of wind during the operation of the opening setting device or is exposed to a strong wind during fixing, the shoji may suddenly rotate and deform suddenly and impair safety.
[0003]
For this reason, the opening window may be used in combination with an opening degree adjuster that prevents inadvertent rotation and deformation of the shoji together with the opening degree setting device. Among such opening degree adjusters, the arm type and sheath type adjusters do not have a function of preventing tilt due to gusts.
Some hydraulic dampers are interposed between the window frame and the shoji. However, such hydraulic dampers have a problem that the cost is high and the force required to open and close the shoji is excessive.
[0004]
[Problems to be Solved by the Invention]
An object of the present invention is to solve the problems in the conventional techniques described above, and to provide a window opening adjuster that can be used stably over a long period of time and can be manufactured at low cost.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention was conceived with the aim of making the pressing mechanism simple and stable in a brake system in which a sliding arm is pressed against the surface of a brake pad. is there.
That is, the window opening degree adjuster of the present invention (Claim 1) includes a cylindrical main body having a hollow portion rotatably attached to a window frame of a case window or a shoji, and a brake disposed in the hollow portion of the main body. A pin, a pinch roller that faces the brake pad and can be contacted and separated from the brake pad, and is rotatably arranged in the hollow portion of the main body, and the brake pad and the pinch in the hollow portion of the main body an arm rotatably mounted on the sash or window frame of penetrating and open at one end the window between the rollers, only including, the pinch roller is arcuate or V-shaped provided on opposite side walls in the body It is pivotally supported by a pair of opening part including the bottom of this so that rolling is possible .
[0006]
According to this, in the operation of the opening setting device attached to the opening window, if the opening window shoji is covered by gusts or strong winds, the arm slides by the rotational movement of this shoji, and according to the slide While the pinch roller rotates , the rotation shaft of the pinch roller rolls on the arcuate or V-shaped bottom of the pair of openings provided in the main body and moves in the sliding direction of the arm and approaches the brake pad. As a result, the arm that has started to slide is firmly sandwiched between the brake pad and the pinch roller and is brought into a brake state, so that it immediately stops. Thereby, careless rotation and deformation | transformation of a shoji can be prevented, and a user's safety can be aimed at.
Moreover, since the pinch roller can be separated from the brake pad by slightly rotating the shoji in the opposite direction, the brake state can be released quickly and easily. That is, when the shoji is pushed in the opposite direction to the direction struck by the gust or strong wind and the arm is slid in the opposite direction, the rotation shaft of the pinch roller rolls in the opposite direction by the sliding of the arm, and the circle Move to the lowest part of the base of the arc or V shape. As a result, the arm can be easily separated from the brake pad, and the brake state can be quickly released .
[0007]
Therefore, the mechanism is simple, can be used stably over a long period of time, and can be manufactured at low cost. One of the main body and one end of the arm is always attached to the shoji and the other is attached to the window frame .
The bottom of the arc or V-shape is a cam surface and includes shapes such as an ellipse, a cycloid curve, and a combination of an inclined line and a curve in addition to various shapes described later.
[0008]
Furthermore, the present invention includes a window opening degree adjuster (Claim 2 ) in which a bearing portion that receives the rotation shaft of the pinch roller is provided at the center of the bottom of the arc shape or V shape in the opening. It is. According to this, since the rotating shaft of the pinch roller is normally received by the bearing portion, the opening / closing operation of the shoji and the operation of the opening setting device are not hindered. Moreover, when the shoji is struck by a gust or strong wind, the rotation shaft of the pinch roller rises from the bearing and rolls on the bottom of the arc or V shape. As a result, when hit by a gust or strong wind, the arm can be pinched between the pinch roller and the brake pad to reliably stop the shoji.
[0009]
Further, the present invention includes a window opening degree adjuster (Claim 3 ) in which the brake pad is attached to the hollow portion of the main body so as to be able to contact and separate from the pinch roller. According to this, together with the pinch roller approaching and separating from the brake pad, the brake pad itself is preliminarily approached or separated from the pinch roller, thereby adjusting the gap between them and sandwiching them between them. It is possible to reliably obtain the brake state of the arm.
The position of the brake pad is adjusted even when the surface of the brake pad is worn or deteriorated due to aging and use over time. Also, the brake pad contacting / separating operation is performed, for example, by changing the position of the brake support that supports the brake pad with a support bolt that passes through the long hole drilled in the main body.
[0010]
In addition, according to the present invention, the main body includes a pair of openings including an upper half body having a substantially channel shape in section to which the brake pad is attached, and the bottom side that accommodates the pinch roller and pivotally supports the rotation shaft. A window opening degree adjuster (Claim 4 ) is also included, which is formed by connecting a pair of side walls and a lower half body having a substantially channel shape provided upward.
According to this, the brake pad is attached to the upper half body so that the position can be adjusted, and the lower half body is pivotally supported by a pair of openings including an arcuate bottom that opens the rotation shaft of the pinch roller upward. In the state, the cylindrical main body can be easily assembled by connecting the side walls of the upper half and the lower half. In addition, the window opening degree adjuster can be assembled at low cost by passing the arm through the gap between the brake pad and the pinch roller facing each other in the hollow portion of the main body.

Moreover, the shoji 4 consists of the upper eaves 4a, the lower eaves 4b, and a pair of left and right vertical eaves 4c, 4d, and the glass G is fitted inside the enclosure. The pair of upper and lower pivot hinges 3 and 3 are arranged in the middle between the upper frame 2a and the upper collar 4a and in the middle between the lower frame 2b and the lower collar 4b.
[0012]
A rotary handle 5 used for opening / closing the shoji 4 is attached to the left vertical shaft 4c of the shoji 4 and a known tightening mechanism is operated by the handle 5.
As shown in FIG. 1A, between the lower frame 2b and the lower heel 4b, an opening setting device 6 that can set the opening of the shoji 4 in any of three stages of, for example, 30, 45, and 90 degrees. Is attached. The setting device 6 includes a metal fitting 7 on the lower collar 4b side, a metal fitting 8 on the lower frame 2b side, a slide plate 9 positioned between the metal fittings 7 and 8, and the like.
Further, as shown in FIGS. 1A and 1B, a window opening degree adjuster 10 of the present invention is attached between the upper frame 2a of the window frame 2 and the upper collar 4a of the shoji 4. .
[0013]
As shown in FIGS. 1 (B) and 1 (C), the window opening adjuster 10 has an L-shaped metal fitting 15 screwed to the upper frame 2a of the window frame 2 and a pin 17 below the metal fitting 15. A rectangular tube-shaped main body 16 that is rotatably supported, a long arm 12 that slidably penetrates the hollow portion S of the main body 16, and one end of the arm 12 that is rotatably connected by a pin 13; And an L-shaped bracket 14 screwed to the upper collar 4a of the shoji 4. A brake pad and a pinch roller, which will be described later, are attached to the hollow portion S of the main body 16 at positions facing each other across the front surface and the back surface of the arm 12.
Note that upper and lower half bodies, which will be described later, forming the metal fittings L and 14, the arm 12, and the main body 16 are made of a stainless steel plate or a bent material thereof.
[0014]
In order to open the shoji 4 of the opening window 1, the handle 5 is turned to release the tightening mechanism, and the shoji 4 is pushed to the outdoor side while the handle 5 is held. As a result, as shown in FIG. 2 (A), the shoji 4 rotates so that the vertical gutter 4c moves to the outdoor side (the depth direction in the drawing). With this rotation, the arm 12 of the window opening degree adjuster 10 slides in the hollow portion S of the main body 16 toward the L-shaped bracket 14, and the main body 16 also depends on the slide and the rotation of the shoji 4. It rotates sequentially under the L-shaped bracket 15.
[0015]
When the shoji 4 is further pushed to the outdoor side, as shown in FIG. 2B, the shoji 4 is maximized when the opening degree is 90 degrees perpendicular to the window frame 2 and the upper frame 2a in plan view. While being opened, the opening setting device 6 fixes the opening. As a result, it is possible to ensure the amount of ventilation into the room.
However, the shoji 4 may be covered by a gust or strong wind during the above rotation operation and before fixing by the setting device 6. In such a case, in order to avoid the situation where the shoji 4 swings and the safety of the user is deteriorated or the shoji 4 is deformed, the window opening degree adjuster 10 of the present invention is used to stop the shoji 4 quickly. Is effectively utilized.
[0016]
3A to 3C show the main body 16 in the window opening degree adjuster 10, the pinch roller 20, the brake pad 31, and the like attached thereto. The main body 16 is composed of an upper half 18 and a lower half 19 having a substantially channel shape in cross section, and these are connected to face each other to form a rectangular tube shape. As shown in FIG. 3A, the upper half 18 includes a ceiling piece 22 and a pair of left and right side walls 23, and a rectangular opening 24 that opens downward is formed at the center of each side wall 23. Yes. In addition, female screw holes 25 for connecting to the lower half body 19 are drilled on both sides of the opening 24 in each side wall 23, and vertically long slots 26 are symmetrically formed on both sides above each side wall 23. Perforated. Further, a through hole 27 for supporting the L-shaped bracket 15 is formed in the center of the ceiling piece 22.
[0017]
On the other hand, as shown in FIG. 3 (A), the lower half 19 includes a bottom piece 32 and a pair of left and right side walls 33, and an opening that opens upward at the center of each side wall 33 and includes an arcuate bottom 35. 34 is formed symmetrically. In addition, through holes 36 for connecting to the upper half 18 are formed in the side walls 33 on both sides of the opening 34 symmetrically.
As shown in FIGS. 3B and 3C, in order to attach a brake support 30 made of metal or hard resin and a brake pad 31 integrally fixed to the bottom surface of the upper half 18, the brake Support bolts 28 are screwed into the female screw holes (not shown) drilled in the side surface of the support 30 from the outside through the long holes 36 of the upper half 18.
The brake pad 31 is made of a synthetic rubber such as chloroprene rubber having a large friction coefficient. Further, the height of the brake pad 31 is adjusted by changing the position where the support bolt 28 penetrates the long hole 36.
[0018]
On the other hand, as shown in FIG. 3 (A), the rotating shafts 21 and 21 of the pinch roller 20 are rotatably mounted on the bottom sides 35 and 35 of the left and right openings 34 and 34 in the lower half body 19. The pinch roller 20 is accommodated inside the lower half 19. The roller 20 has at least a roll peripheral surface formed of, for example, silicon rubber.
Next, as shown in FIGS. 3 (B) and 3 (C), with the side walls 23, 23 of the upper half adjacent to the inner side of the side walls 33, 33 of the lower half 19, the females are passed through the through holes 36. Screws (not shown) are screwed into the screw holes 25. As a result, the main body 10 having a rectangular tube shape and having the brake pad 31 and the pinch roller 20 attached to the hollow portion S facing each other is formed. At this time, since the upper and lower openings 24 and 34 overlap each other, one irregular hole is formed in a side view.
[0019]
Further, by inserting a pin 17 penetrating the horizontal piece 15b of the L-shaped bracket 15 through a washer 39 into the through hole 27 of the ceiling piece 22 of the upper half 18 in the main body 10, the bottom of the L-shaped bracket 15 is inserted. The main body 16 can be rotatably supported on the side.
Further, the main body 16 is rotatably attached to the window frame 2 by screwing the L-shaped metal fitting 15 to the upper frame 2a of the window frame 2 from the through hole 15a.
As shown in FIGS. 1B and 1C, the arm 12 having one end rotatably connected to the L-shaped metal fitting 14 previously screwed to the upper collar 4a of the shoji 4 via the pin 13 is also provided. The end is passed between the brake pad 31 and the pinch roller 20 facing each other in the main body 16. Thereby, the window opening degree adjuster 10 mentioned above is assembled. A stopper for retaining the arm 12 may be provided at the other end of the arm 12 through which the main body 16 has passed.
[0020]
Here, the operation of the window opening adjuster 10 will be described with reference to FIGS.
FIG. 4 (A) shows a state in which the shoji 4 of the casement window 1 is shifted from the closed state shown in FIGS. 1 (B) and (C) or from the closed state to the open state shown in FIGS. 2 (A) and 2 (B). Fig. 5 shows a state in the vicinity of the hollow portion S of the main body 16 in the window opening degree adjuster 10. The heights of the brake pad 31 and the brake support 30 are adjusted in advance by the support bolt 28.
As the shoji 4 is opened, the arm 12 whose one end is pivotally supported by the L-shaped bracket 14 of the shoji 4 slides in the right direction as indicated by the arrow in FIG. The pinch roller 20 whose roll surface is in contact with the sliding arm 12 also rotates about the vicinity of the lowest portion of the arc-shaped bottom 35 of the opening 34 of the rotating shaft 21.
[0021]
By the way, a gust of wind that is the same as or opposite to the opening direction during the opening operation of the shoji 4 may be received. For example, when a gust of wind opposite to the opening direction hits the shoji 4, the arm 12 strongly pressed by the metal fitting 14 starts to slide rapidly in the left direction as indicated by the arrow in FIG. As the arm 12 slides, the pinch roller 20 rotates while being strongly pressed on its roll surface as shown in FIG. 4 (B), and the rotation shaft 21 is also left on the arcuate base 35 in the opening 34. Pressed.
As a result, the position of the rotary shaft 21 rises and the pinch roller 20 also rises, so that a brake state is reached in which the arm 12 is instantaneously sandwiched between the brake pad 31 and the brake pad 31. Therefore, since the arm 12 is stopped and the opening degree of the shoji 4 can be kept against the gust at the stop position, the safety of the user can be achieved.
[0022]
When the shoji 4 is pushed again in the opening direction after the gust of wind has settled, the pinch roller 20 simply returns from the brake state of FIG. 4 (B) to the state of FIG. 4 (A).
If a gust of wind in the same direction as the opening direction hits the shoji 4, the pinch roller 20 moves in the right direction on the bottom 35 of the opening 34 in FIG. The arm 20 is sandwiched between the roller 20 and the brake pad 31 and stopped. Further, after the gust of wind, by pushing the shoji 4 in the closing direction, it is possible to quickly and easily return to the state of FIG.
[0023]
According to the window opening adjuster 10 as described above, the shoji 4 can be reliably and safely stopped immediately even if a gust of wind is generated during the opening or closing operation of the opening window 1, and the stopped state can be easily released. Can do. In addition, since it consists of a simple mechanism in the arm 12 and the main body 16, it can be used safely over a long period of time without being prone to failure.
The opening setting device 6 may be omitted and only the window opening adjuster 10 may be attached to the opening window 1. In this case, the window opening degree adjuster 10 may be attached between the lower frame 2b and the lower rod 4b.
[0024]
The present invention is not limited to the embodiment described above.
In place of the opening 34 of the main body 16, as shown in FIG. 4C, an opening 34 a having a bearing portion 37 that is shallowly recessed in a round shape at the center of the arc-shaped base 35 is formed on the lower half 19. You may form in the side wall 33. FIG. That is, the rotating shaft 21 of the pinch roller 20 is normally received in the bearing portion 37 and does not hinder the operation of opening or closing the shoji 4 and when the shoji 4 is hit by a gust of wind, the pinch roller 20 The rotating shaft 21 rises from the bearing portion 37 and rolls on the arcuate base 35. As a result, a brake state is reached in which the arm 12 is sandwiched and stopped between the pinch roller 20 and the brake pad 31.
[0025]
Further, instead of the opening 34 of the main body 16 (side wall 33), as shown in FIG. 4 (D), as an opening 34b including a V-shaped bottom side 38 composed of inclined sides 38a, 38a symmetrically, as shown in FIG. It is possible to obtain the same operation and effect as the opening 34.
Furthermore, as shown in FIG. 4 (E), an opening 34c having a bottom side 38 made up of symmetrically inclined sides 38a, 38a and a bearing portion 39 that is shallowly recessed in a round shape at the center thereof may be used. Thereby, the rotating shaft 21 is received by the bearing part 39 in the normal state of the pinch roller 20, and the shoji 4 can be stopped in the same manner as described above in the case of a gust of wind.
Contrary to the window opening adjuster 10, the L-shaped bracket 14 is fixed to the window frame 2, the shoji 4 is fixed to the L-shaped bracket 15, and a main body 16 is attached thereto. Even if they are attached in the same manner, similar actions and effects can be obtained.
[0026]
Further, two pinch rollers 20 and openings 34 may be provided in series in the main body 16 along the longitudinal direction of the hollow portion S. At this time, the rotation shafts 21 of the two pinch rollers 20 are individually supported by the two openings separated from the left and right halves of the bottom 35 of the opening 34, or the two openings separated for each of the inclined sides 38a. The rotary shaft 21 of the roller 20 may be supported in the same manner as described above. These forms are also included in the arc-shaped or V-shaped bottom of the opening 34 or the like.
The main body 16 may be an integral square steel pipe having a hollow portion S on the inside or a hollow extruded shape of an aluminum alloy.
In addition, the opening window to which the present invention is applied includes a configuration in which a hinge is arranged between one vertical fence of the shoji and the vertical frame of the window frame as long as it rotates in the vertical axis.
[0027]
【The invention's effect】
According to the window opening adjuster of the present invention described above (Claim 1), the arm slides when the shoji is obstructed by a gust of wind, and the pinch roller rotates in accordance with this and moves in the arm sliding direction. At the same time, it is moved closer to the brake pad. Specifically, the pinch roller that rotates by the sliding of the arm rolls on the bottom of the arc shape or V shape in the opening provided in the main body and reliably approaches the brake pad side . As a result, the arm that has started to slide enters a braking state in which the arm is firmly sandwiched between the brake pad and the pinch roller, and immediately stops.
[0028]
Moreover, since the pinch roller can be separated from the brake pad by slightly rotating the shoji in the opposite direction, the brake state can be quickly and easily released. Specifically, when the shoji is pushed in the direction opposite to the direction struck by the gust of wind, the arm's slide causes the pinch roller's rotation shaft to roll in the opposite direction to the bottom of the arc-shaped or V-shaped bottom. Moving. As a result, the brake state can be easily released and the brake state can be quickly released.
Therefore, careless rotation of the shoji can be prevented and user safety can be achieved .
[0029]
Further, according to the window opening adjuster of the second aspect , since the rotation shaft of the pinch roller is normally received by the bearing portion, it does not hinder the operation of opening / closing the shoji and the opening setting device. Moreover, when the shoji is hit by a gust of wind, it can be stopped immediately.
According to the window opening degree adjuster of the third aspect , together with the pinch roller approaching and separating from the brake pad, the brake pad itself is previously approached or separated from the pinch roller to adjust the gap between the two. Thus, the arm sandwiched between them can be surely brought into a brake state.
[0030]
In addition, according to the window opening degree adjuster of claim 4 , the cylindrical body can be easily assembled by connecting the side walls of the upper half and the lower half, and the hollow portion of the body The adjuster can be assembled at low cost by passing the arm through the gap between the brake pad and the pinch roller facing each other.
