Description

The present invention relates to fittings, and more particularly to fittings in which a damper is provided between a frame and a fitting.

Some fittings include a damper called a stay damper between the vertical frame of the frame and the vertical stile of the shoji in order to stabilize the opening/closing operation of the shoji with respect to the frame. Generally, two dampers are provided, one on each side of the frame and the shoji (for example, see Patent Document 1).

Publication No. 4-14632

By the way, the designs of modern buildings are diversifying, and there is also a demand for fittings with large opening areas. However, the damper that supports the shoji has a maximum allowable weight that guarantees its operation. For this reason, even when a frame with a large opening area is set, it is difficult to arrange a shoji that exceeds the maximum allowable weight of the two dampers inside the frame. For this reason, conventionally, the only way to deal with this is to place a medium aggregate inside the frame and divide the shoji into multiple parts, which imposes major restrictions on the design.

In view of the above-mentioned circumstances, an object of the present invention is to provide a fitting that allows a damper to be placed between a frame and a shoji screen without imposing any major restrictions on the design.

In order to achieve the above object, the fittings according to the present invention include a frame body provided with a frame on each of its four circumferences, and a shoji in which a frame is provided on each of the four circumferences of a rectangular facing material, and the shoji includes: The tip stile on the distal side is supported so as to be opened with the tip stile on the distal side protruding out of one surface of the frame body with the center of the axis along the length of the proximal stile serving as the proximal end, and the proximal stile and the tip A fitting is provided with a damper that operates as the shoji opens and closes between a side stile provided between both ends of the stile and a side frame of the frame provided corresponding to the side stile. The shoji is connected by an intermediate stile disposed along the side stile at a portion where the base end stile and the tip stile are on one side of the face material, and when closed. The face material is supported by the frame in a state facing out of one surface of the frame, and the frame has a base end frame provided corresponding to the base end stile and a base end frame provided corresponding to the base end stile, and a base end frame provided corresponding to the base end stile, The end frames provided correspondingly are connected to each other by an intermediate frame disposed along the side frame at a portion of the shoji that is on one side of the face material, and the intermediate frame and the intermediate frame are It is characterized in that an intermediate damper is provided in between, which operates as the shoji opens and closes.

According to the present invention, an intermediate stile is added to the stile without dividing the face material of the shoji, and an intermediate damper is provided between the intermediate stile and the intermediate frame of the frame body. Therefore, the weight of the shoji can be supported by the dampers on both sides and the intermediate damper, and the size (weight) of the shoji can be increased by the maximum allowable weight set for the dampers. Moreover, when looking at the fittings from the outside of one side where the shoji protrudes, the intermediate stile and frame are covered by the placement of the facing material, so there is no risk of deteriorating the appearance quality. It also becomes possible to eliminate design constraints.

On the other hand, the shoji 20 of the fittings 1 has an upper stile (tip stile) 22, a lower stile (base end stile) 23, and left and right vertical stile (side stile) 24 attached to the four circumferences of a rectangular face material 21. The upper stile 22 and the lower stile 23 are connected to each other by an intermediate stile 26 extending vertically. In this embodiment, a horizontally long rectangular double-glazed glass having a substantially similar shape to the frame 10 is used as the face material 21. Furthermore, the upper stile 22, the lower stile 23, and the left and right vertical stile 24 have the same cross-sectional shape, and are mitered between their ends. The upper stile 22, the lower stile 23, the vertical stile 24, and the middle stile 26 are extruded shapes made of metal such as aluminum alloy or resin, and each is configured to have a uniform cross-sectional shape over the entire longitudinal length. There is. Note that the longitudinal direction of the frames 22, 23, 24, and 26 also corresponds to the extrusion direction when extrusion molding each of them.

In the illustrated example, the upper stile 22, the lower stile 23, and the left and right vertical stile 24 are composed of a stile base wall 25a, an outer stile wall 25b, an inner stile wall 25c, and a stile side mounting wall 25d.

A stile tight material 25f is attached along the length of the stile 22, 23, 24 at the outer peripheral edge of the interior facing surface 25c1 of the stile inner wall 25c. These stile outer wall portion 25b and stile inner wall portion 25c have a larger protrusion dimension toward the inner circumference than a protrusion dimension toward the outer circumference from the stile base wall 25a, and their protrusion dimensions toward the outer circumference are mutually larger. Almost equal. The protrusion dimension of the stile inner wall 25c from the stile base wall 25a toward the inner peripheral side is set larger than that of the stile outer wall 25b. The stile-side mounting wall 25d extends toward the interior of the room from the inner circumferential edge of the interior-facing surface 25c1 of the stile inner wall 25c along the direction of view, and has a dimension along the direction of view. It has a hollow rectangular shape that is larger than the dimension along the finding direction. To explain in more detail, the stile-side mounting wall 25d has almost the same dimension along the finding direction as the frame-side mounting wall 14b, and extends from the inner circumferential surface 25d1 to the outer periphery of the stile inner wall 25c. The dimension up to the side end surface 25c2 is configured to be approximately the same as the dimension along the finding direction of the frame base 14a. Moreover, when the frame tight material 14e is brought into contact with the surface 25d2 of the frame-side mounting wall 14b facing the room, the frame tight material 25f can come into contact with the surface 14b2 of the frame-side mounting wall 14b facing the outdoors. It is structured as follows. The above-mentioned upper stile 22, lower stile 23, and left and right vertical stile 24 are arranged between the ends with the edges of the facing material 21 accommodated in the respective facing material receiving grooves 25e via the glazing channel 27a and the sealing material 27b. By mitering these, they will be attached to the four circumferences of the face material 21. When the frames 22, 23, 24 are attached to the edges of the face material 21, when housed in the frame 10, the frame tight members 25f of the frames 22, 23, 24 are attached to the corresponding frames 11, 12, 24 on the four circumferences. 13, and the frame tight members 14e of the frames 11, 12, 13 come into contact with the frame-side mounting walls 25d of the corresponding frames 22, 23, 24.

The intermediate stile 26 includes an intermediate stile base wall 26a and two stile intermediate mounting walls 26b. The intermediate stile base wall portion 26a has a flat plate shape along the finding direction. On the surface 26a1 of the intermediate stile base wall portion 26a facing the interior of the room, two intermediate stile tight members 26c are attached to the center portion along the length thereof. The two intermediate stile tight members 26c are spaced apart from each other so that they can simultaneously contact the exterior facing surface 15b2 of the frame intermediate mounting wall 15b provided on the intermediate frame 15. The stile intermediate mounting wall portion 26b has a hollow rectangular shape that extends toward the interior of the room along the prospective direction from both longitudinal edges of the surface 26a1 of the intermediate stile base wall portion 26a facing the interior of the room. be. The dimension from the outer peripheral surface 26b1 of one stile intermediate mounting wall 26b to the outer peripheral surface 26b1 of the other stile intermediate mounting wall 26b is approximately the same as the dimension along the finding direction of the intermediate frame base 15a. The dimensions of the stile intermediate mounting wall portion 26b along the prospective direction and the dimension along the facing direction are approximately the same as the dimensions of the stile side mounting wall portion 25d along the prospective direction and the dimension along the facing direction, respectively. A space is ensured between the frame intermediate mounting wall portions 26b to allow the frame intermediate mounting wall portions 15b of the intermediate frame 15 to be placed. When the intermediate stile 26 is opposed to the intermediate frame 15 and the intermediate frame tight material 15c is brought into contact with the surface 26b2 of the stile intermediate mounting wall portion 26b facing the interior of the room, the intermediate stile tight material 26c is connected to the frame intermediate mounting wall. It comes into contact with the surface 15b2 of the portion 15b facing outdoors. This intermediate stile 26 extends vertically at equal intervals from the left and right vertical stile 24, and the surface 26a2 of the intermediate stile base wall 26a facing the outdoors is connected to the interior wall 25c of the vertical stile 24. It is connected to the upper stile 22 and the lower stile 23 in a state that coincides with the facing surface 25c3. As is clear from FIG. 5, cutouts 22a and 23a are formed in the upper stile 22 and the lower stile 23 at portions located between the stile intermediate mounting wall portions 26b. Further, the intermediate frame 26 and the face material 21 are bonded to each other by a sealing material (buffering material) 28 and a backup material (buffering material) 29 interposed between them.

By arranging the hinge member 30 between the lower stile 23 and the lower frame 12, the shoji 20 having the above configuration can be rotated around the hinge axis 31 along the length of the lower stile 23. It is supported by the frame 10 as shown in FIG. Pulleys 41 and 42 are provided on the upper stile 22 and the upper frame 11, respectively, and operating wires (not shown) are wound around these pulleys 41 and 42. When the operation wire is wound and operated, the mutual distance between the pulleys 41 and 42 becomes shorter, the upper stile 22 and the upper frame 11 are placed close to each other, and the shoji 20 is maintained in a closed state with respect to the frame 10. be done. When the operating wire is loosened, the distance between the pulleys 41 and 42 increases, so that the shoji 20 can be opened with the upper stile 22 protruding outside. Even when the shoji 20 is in the open state, if the operation wire is wound up again, the upper stile 22 will be drawn to the upper frame 11, and the shoji 20 can be returned to the closed state. When the shoji 20 is closed with respect to the frame 10, the frame intermediate mounting wall 15b of the intermediate frame 15 is arranged between the frame intermediate mounting walls 26b of the intermediate stile 26, and the frame intermediate mounting wall 15b and the frame An accommodation space 2A surrounded by the intermediate stile base wall 26a and the intermediate frame base 15a is formed between the intermediate mounting wall 26b and the frame side mounting wall 14b of the vertical frame 13 and the stile side of the vertical stile 24. The mounting walls 25d are arranged to face each other, and an accommodation space 2B surrounded by the frame base 14a and the stile inner wall 25c is configured between the frame-side mounting wall 14b and the stile-side mounting wall 25d. It turns out.

Furthermore, in this fitting 1, dampers 3B are respectively arranged in the accommodation spaces 2B between the left and right vertical stile 24 and the vertical frame 13, and two dampers 3B are provided in the accommodation spaces 2B between the intermediate stile 26 and the intermediate frame 15. Intermediate dampers 3A are arranged in each space 2A. The damper 3B and the intermediate damper 3A are called stay dampers having the same configuration, and the maximum allowable weights are also set to the same value. The damper 3B has one end rotatably supported on the frame-side mounting wall 25d of the vertical stile 24, and the other end rotatably supported on the frame-side mounting wall 14b of the vertical frame 13. be. The intermediate damper 3A has one end rotatably supported on the frame intermediate mounting wall 26b of the intermediate stile 26, and the other end rotatably supported on the frame intermediate mounting wall 15b of the intermediate frame 15. It is. The support centers of the damper 3B and the intermediate damper 3A are both parallel to the hinge axis 31 of the hinge member 30, and are arranged so that the end supported on the shoji 20 is higher than the end supported on the frame 10. It has been set up. These dampers 3B and intermediate dampers 3A expand and contract as the shoji 20 is opened and closed, making it possible to stabilize the opening and closing operations of the shoji 20. Moreover, since one shoji 20 is supported by a total of four dampers 3B and 3A, even if dampers with the same maximum allowable weight are used, it will not be supported by two dampers on both sides as in the past. It becomes possible to support the shoji 20 which is heavier than the shoji 20. Furthermore, the intermediate stile 26 and the intermediate frame 15 are both disposed closer to the indoor side than the face material 21, and are not exposed to the outdoor side. Therefore, it becomes difficult to visually recognize the intermediate stile 26 and the intermediate frame 15 from the outside of the room, which is extremely advantageous in terms of appearance quality.

There's no need. For example, it may be a projecting window configured such that the lower stile protrudes out of the plane with the upper stile part of the shoji as the center, or it may be a projecting window in which one vertical stile is the center and the other vertical stile protrudes into the panel. It may be a casement window configured as follows. Further, the window is not necessarily limited to a hinge, and may be configured as a sliding window. Furthermore, although the frame constituting the frame body and the stile constituting the shoji screen each have the same cross-sectional shape on all four sides, the present invention is not limited to this. The facing material of the shoji does not need to be double-glazed glass, and the shoji may be constructed of a non-light-transmitting member such as an aluminum panel.

Further, in the above-described embodiment, one intermediate stile and one intermediate frame are provided, but it is also possible to configure a fitting by providing two or more intermediate stile and intermediate frames. Furthermore, although the intermediate dampers are arranged at two positions symmetrical to each other with respect to the virtual bisector plane along the length of the intermediate frame 26, the number of intermediate dampers does not need to be two. Instead, for example, one intermediate damper may be provided in each side stile and intermediate stile on both sides.

Furthermore, in the above-described embodiment, since the intermediate stile and the intermediate frame are each provided with an intermediate mounting wall, the intermediate damper is prevented from being exposed to the outside when the shoji is closed, and the appearance quality is improved. It becomes possible to aim for improvement. However, it is not always necessary to provide an intermediate mounting wall. In this case, the intermediate damper may be configured to be attached to the facing surface of the intermediate stile and the facing surface of the intermediate frame. In addition, in the embodiment described above, when providing intermediate mounting walls, they are provided on both sides of the intermediate stile and at the center of the intermediate frame. I don't mind.
