  However, the twist-absorbing device for the window opening / closing link disclosed in Patent Document 1 exposes a wide range of the structure in which the link is folded or opened when the window is opened / closed. There was a problem that the user could accidentally pinch a finger or the like during the operation. Further, when opening and closing the window, as many as six rotating shafts must be provided in order to control the movement of each rod, and the structure is very complicated. Furthermore, since the opening angle of the window is limited, there is no risk that a small child will accidentally fall from the window, and it is inconvenient that the outside surface of the window cannot be cleaned indoors. There was a face.

  On the other hand, the switch such as a door of Patent Document 2 has a relatively simple structure because the movement of the outer cylinder and the insertion member is controlled by a small number of rotating shafts. However, for example, in the case of a vertical axis rotating window in which a door or the like is pivotally attached to the vertical frame portion of the window frame, this door switch is attached between the lower frame portion of the window frame and the lower frame portion of the door or the like. Therefore, it is easy to accidentally pinch fingers during the opening / closing operation. Furthermore, like patent document 1, there existed the inconvenient surface that the surface outside a window could not be cleaned indoors.

  The present invention has been made in view of the above-mentioned background art, and provides a safe and easy-to-use window opening / closing controller capable of realizing a function of limiting and holding the opening angle of the shoji with a simple structure. For the purpose.

Accordingly, as shown in FIG. 6, the shoji bracket 22 is movable freely swingable and rotatable with respect to the arm 20 by a so-called ball joint structure which is a universal joint.

  As shown in FIGS. 2 and 3, the case 18 is attached to the window frame 14 via a frame bracket 24. The frame bracket 24 is made of a plate material having two flat surfaces bent in an L shape, and one of the flat surfaces is a fixing portion 24a fixed to the window frame 14 in a contact state. In the other plane, a shaft 24b that is inserted into the shaft hole 18c of the case 18 and supports the case 18 is erected at the center portion, and the case 18 can be rotated in parallel with the inward side surface of the window frame 14, and The case support 24c is supported to be swingable with respect to the side surface of the window frame within a range of a predetermined inclination angle or less. Here, the swingable tilt angle is set to 0 to 10 degrees.

  Next, the configuration of the arm positioning mechanism 26 will be described with reference to FIGS. As shown in FIG. 7, the arm positioning mechanism 26 includes a guide 28, a stopper substrate 30, a stopper pin 32, a spring 34, and a stopper release button 36. FIG. 7 shows a state where the arm positioning mechanism 26 is not operating and the arm 20 is slidable.

  As shown in FIG. 8, the guide 28 is provided with a front wall 38 and a rear wall 40 that close the front opening end 18 a of the case 18 at a predetermined interval, and lower ends thereof are connected by a bottom plate 42. The arm 20 is inserted in a slightly upper part of the front wall 38 and the rear wall 40 to form an arm hole 44 that slidably supports the arm 20, and further slightly below the arm hole 44 of the front wall 38. In this portion, a pair of left and right insertion ports 48 into which a stopper release member 46 described later is inserted are formed. A spring holding groove 42 a that holds the lower end portion of the spring 34 is provided on the upper surface of the bottom plate 42.

  The stopper substrate 30 is a rectangular plate having an outer shape that fits in a space between the front wall 38 and the rear wall 40 of the guide 28 with a slight clearance, and as shown in FIG. 9, a pair of side walls 30a standing from the left and right ends. have. The distance between the pair of side walls 30 a is wider than the width of the arm 20. Further, a stopper pin 32 is integrally provided at the center of the upper surface 30b of the stopper substrate 30 so as to protrude in a direction in which the side wall 30a stands. When the arm 20 slides and protrudes from the case 18 by a predetermined length, the stopper pin 32 functions as a stopper member that fits the head portion 32a into the arm positioning hole 18c and stops the sliding operation. Further, the head 32 a of the stopper pin 32 is provided with an inclined surface 32 b that is inclined in one direction.

  The spring 34 is a coil spring having an isosceles trapezoidal shape when viewed from the side. The spring 34 has a large diameter that fits in the spring holding groove 42 of the guide 28, and the upper end is small enough to fit with the lower end of the stopper pin 32. It has a diameter. The spring 34 functions as a biasing means that biases the stopper pin 32 toward the arm 20 in the assembled state.

  As shown in FIG. 10, the stopper release button 36 has a rectangular substrate 36a similar to the stopper substrate, a pressing portion 36b projecting hollow at the center thereof, and a direction opposite to the pressing portion 36b from the left and right end portions of the substrate 36a. A pair of leg portions 36c.

  The guide 28, the stopper substrate 30, the stopper pin 32, the spring 34, and the stopper release button 36 are assembled as shown in FIG. First, the lower end portion of the spring 34 is accommodated in the spring holding groove 42a of the bottom plate 42 of the guide 28, and the stopper substrate 30 and the stopper pin 32 are attached to the upper end portion. At this time, it arrange | positions so that the low side of the inclined surface 32b of the stopper pin 32 may face the front side opening end 18a. The stopper pin 32 is biased upward by a compressed spring 34, and the head portion 32 a is locked to the lower surface of the arm 20.

  The stopper release button 36 is disposed so as to straddle the upper surface side of the arm 20 between the substrate 36 a and the pair of legs 36 c, and the lower surface of the substrate 36 a is supported by the pair of side walls 30 a of the stopper substrate 30. Further, the pressing portion 36b of the stopper release button 36 is housed in a button hole 50 having a tip portion opened in the side surface of the case 18, and the upper surface is exposed to the outside.

  Next, the operation of the window opening / closing adjuster 10 when the shoji 12 of the outer window 16 is opened and closed will be described with reference to FIGS. When the shoji 12 is closed, as shown in FIG. 11, in the window opening / closing adjuster 10, the case 18 and the arm 20 are arranged in a direction substantially perpendicular to the floor surface (depth direction in FIG. 11). . The arm 20 is housed deeply in the case 18 as shown in FIGS. 2 and 3, and the arm positioning mechanism 26 is in a state that does not hinder the sliding operation of the arm 20 as described in FIG. Further, the fixing portion 24a of the frame bracket 24 fixed to the window frame 14 and the shoji 12 are positioned in parallel.

  When the shoji 12 is opened to the outside, as shown in FIG. 12, the case 18 rotates about the shaft 24b of the case support 24c of the frame bracket 24, and the front opening end 18a faces the outside. Protruding. At the same time, the arm 20 slides in the case 18 and follows the movement of the opening / closing end of the shoji 12 so that the length of the arm 20 protruding from the case 18 is increased. In addition, the positional relationship between the fixing portion 24a of the frame bracket 24 fixed to the window frame 14 and the shoji 12 changes from an initial parallel state to an oblique state. The movement from the parallel state to the oblique state includes a ball joint structure in which the shoji bracket 22 is attached to the arm 20, and a holding structure in which the case support 24c of the frame bracket 24 holds the case 18 in a swingable manner. Therefore, it is smoothly performed without twisting.

  When the shoji 12 is opened to a predetermined opening angle, the arm positioning hole 20a approaches the portion of the arm positioning mechanism 26. When the arm positioning hole 20a reaches the position of the stopper pin 32, as shown in FIG. 13, the stopper pin 32 is biased by the spring 34, and the head portion 32a is inserted deeply into the arm positioning hole 20a. The stopper substrate 30 also moves in the direction of the arm 20 integrally with the stopper pin 32, and the pressing portion 36 b of the stopper release button 36 supported by the pair of side walls 30 a of the stopper substrate 32 extends from the button hole 50 of the case 18. Protruding.

  By this operation, the arm 20 is restricted in both a sliding operation in a direction protruding from the front opening end 18a of the case 18 and a sliding operation in a direction accommodated in the case 18, and is fixed at this position. Therefore, the maximum opening angle of the shoji 12 is limited by the arm positioning mechanism 26, and the shoji 12 can be held at the maximum opening angle.

  When the shoji 12 is closed, the operation of the arm positioning mechanism 26 is released by pushing the pressing portion 36b of the stopper release button 36 with a finger. When the stopper release button 36 is pressed and pushed back in the direction opposite to the bias of the spring 34, the stopper substrate 30 and the stopper pin 32 also move in the same direction, and as shown in FIG. A part is pushed out of the arm positioning hole 20a. Accordingly, in the state shown in FIG. 14, when a force is applied in such a direction that the arm 20 is accommodated in the case 18, the stopper pin 32 is pushed out by the force with which the inner peripheral edge of the arm positioning hole 20 a comes into contact with the inclined surface 32 b. As a result, the arm 20 becomes slidable and the shoji 12 can be closed. On the contrary, in the state shown in FIG. 14, even if a force is applied in a direction to further open the shoji 12, that is, a direction in which the arm 20 protrudes from the case 18, the outer peripheral side surface of the head 32 a of the stopper pin 32 is positioned in the arm position. The arm 20 is locked to the inner peripheral edge of the hole 20a, and the arm 20 cannot slide, and the holding state of the arm 20 is maintained. Therefore, even when the operation of the arm positioning mechanism 26 is released, there is no possibility that the shoji 12 is accidentally opened beyond the maximum opening angle, so that it is safe even if a small child misoperates.

  Next, in the maintenance of the shoji 12 and the like, the operation of releasing the restriction of the maximum opening angle of the shoji 12 regulated by the arm positioning mechanism 26 of the window opening / closing adjuster 10 using the stopper releasing member 46 will be described with reference to FIGS. This will be described with reference to FIG.

  As shown in FIG. 15, the stopper release member 46 includes a grip portion 52 that becomes a handle portion of the user, and an elongated rod-like portion that extends substantially in parallel from the grip portion 52. It comprises a pair of insertion pieces 54 formed so as to be insertable into two insertion openings 48 formed in the guide 28.

  As shown in FIG. 16, the stopper release member 46 is used in a state where the arm 20 is housed deep in the case 18 and is slidable. When the insertion piece 54 is inserted from the insertion port 48 of the guide 28, the insertion piece 54 reaches the space between the stopper substrate 30 and the arm 20, and the upper surface 30 b so that the stopper substrate 30 does not move in the direction of the arm 20. Lock. Therefore, even if the shoji 12 is opened from the state of FIG. 16 and the arm positioning hole 20a reaches the position of the stopper pin 32, the head 32a of the stopper pin 32 is fitted into the arm positioning hole 20a as shown in FIG. The sliding movement of the arm 20 is not limited. When the shoji 12 is further opened, as shown in FIG. 18, the arm 20 comes out of the case 18, and the shoji 12 can be opened widely without limitation. Further, when closing the shoji 12 from this state, the operations shown in FIGS.

  The window opening / closing controller 10 of this embodiment has few connecting members such as a rotating shaft for controlling the movement of the case 18 and the arm 20, has a simple structure, and is excellent in maintainability. Further, the structure of the arm positioning mechanism 26 that stops the arm 20 that slides in the case 18 and holds it in a predetermined position is simple, and it is difficult for the constituent members to be worn or deteriorated. Further, by using the stopper release member 46, the operation of the arm positioning mechanism 26 can be easily canceled. If the window is opened wide using the stopper release member 26, the outer surface of the outside opening window 16 can be opened indoors. It can also be cleaned, which is very convenient.

  The window opening / closing adjuster according to the present invention is not limited to the above-described embodiment.
