Description

  The present invention relates to a joinery having a configuration in which a shoji is suspended so as to be slidable with respect to an upper frame.

  As a joinery that partitions indoors and outdoors and indoors and outdoors, there is a joinery having a suspended structure. In this joinery, the shoji is slidably slidable via a suspension door to a rail provided on the upper frame of the frame attached to the opening of the building frame. Thereby, even if it is a heavy shoji, the opening and closing becomes smooth.

  For example, Patent Literature 1 discloses a joinery that supports a folding door, in which a shoji is connected in a foldable manner, inside a frame. This joinery has a suspension door wheel in which a pair of rollers are juxtaposed in the prospective direction at the upper end of the shoji, and the shoji is slidably supported so as to be slid by being hung on the rail of the upper frame.

JP 2006-188910 A

  In the joinery of the above-mentioned patent document 1, a tight material that comes in contact with the finding surface of the shoji is provided on the finding surface of the lower frame attached to the opening of the frame. When the folding door is closed, the tight material is in close contact with the shoji, so that the air tightness and water tightness inside and outside the room are maintained.

  By the way, in this joinery, the shoji as a whole is disposed at a position opposite to the tight material in the prospective direction with respect to the suspension fulcrum of the shoji by the suspension door, specifically the intermediate position between the pair of rollers. Further, a glass plate which is generally the largest weight among the constituent members of the shoji is also disposed at a position close to the side opposite to the tight material with respect to the suspension fulcrum. For this reason, it can be estimated that the position of the center of gravity of the entire shoji is set on the opposite side of the tight material with respect to the suspension fulcrum of the shoji in the prospective direction.

  Therefore, in the fitting of Patent Document 1, when the shoji is slid when the folding door is opened and closed, a force is generated that the shoji swings in a pendulum shape toward the tight material side with the hanging fulcrum of the shoji as a fulcrum. If it does so, the finding surface of a shoji will be strongly pressed by a tight material, the sliding resistance between a shoji and a tight material will become large, and smooth opening and closing operation will be prevented. In particular, in the case of a large joinery in which a plurality of large shojis weighing 90 kg or more are connected, an increase in sliding resistance between the shoji and the tight material ensures smooth opening and closing operability. It becomes a big problem above. And such a problem is a problem which generate | occur | produces similarly in the fittings generally provided with the shoji which slides in the state by which the upper part was suspended including not only a folding door but a sliding door.

  The present invention has been made in consideration of the above-described problems of the prior art, and an object of the present invention is to provide a fitting that can smoothly open and close a shoji whose upper part is suspended and supported.

  In the joinery according to the present invention, a rail is provided along the longitudinal direction of the upper frame, and a tight material is disposed on at least a surface of the upper frame or the lower frame, and a shoji is suspended from the rail, thereby suspending the upper frame. The shoji is slidably disposed along the longitudinal direction of the sliding door, and the tight material is brought into contact with the finding surface of the shoji, and the position of the center of gravity of the shoji is in the prospective direction. It was set so that it might be located between the hanging fulcrum of the said and the said tight material.

  According to such a configuration, the position of the center of gravity of the shoji is set so as to be located between the hanging fulcrum of the shoji and the tight material in the prospective direction. For this reason, the shoji that is suspended by the rail and slides generates a force that swings in a pendulum-like manner with its hanging fulcrum as a fulcrum, and the upper end and lower end of the shoji slide from the tight material. It is slid in a state of swinging in the separating direction. Therefore, it is avoided that a large pressing force is applied from the shoji to the tight material, and the sliding resistance of both is reduced. Thereby, the operation force required to slide the shoji is lightened, and the opening / closing operation is smooth.

  In the joinery according to the present invention, the shoji has a saddle member and a glass plate provided inside the saddle member, and the glass plate is offset to the tight member side in a prospective direction with respect to the saddle member. By installing, it is good to set the gravity center position of the said shoji between the suspension fulcrum of the said shoji and the said tight material in a prospective direction. That is, in a general shoji, the glass plate is often the largest heavy object among the constituent members. Therefore, it is possible to easily set the center of gravity of the shoji as a whole between the suspension fulcrum and the tight material by arranging the glass plate at a position offset to the tight material side in the prospective direction with respect to the saddle material. it can.

  In the joinery according to the present invention, the shoji is suspended from the rail via a suspension door pulley in which a pair of rollers are arranged side by side, and an intermediate position of the pair of rollers is a suspension fulcrum of the shoji. Also good. If it does so, even if it is a large-sized shoji with a heavy weight, it can be stably suspended and supported by the rail of an upper frame with a pair of roller arranged in parallel. In addition, since the middle position of the pair of rollers serves as a suspension fulcrum of the shoji, even when a suspended door pulley having rollers arranged in parallel is used, the force to swing the shoji to the side away from the tight material Can be reliably generated.

  In the fitting according to the present invention, a plurality of the shojis are provided, and a pair of adjacent shojis are foldably connected to each other by a connecting part, and when the sliding part is slid along the rail, the connecting part moves in a prospective direction and opens and closes. The folding door may be configured.

  According to the present invention, it is avoided that a large pressing force is applied to the tight material from the surface where the shoji is found, and the sliding resistance of both is reduced. For this reason, the operation force required to slide the shoji is lightened, and the opening / closing operation is smooth.

The tight material 28 is formed of an elastic member such as rubber or sponge, and is intended to ensure airtightness and watertightness between the inside and outside of the room partitioned by the folding door 16.

  As shown in FIG. 3 and FIG. 4, among the shojis 14 and 15 that constitute the folding door 16, the shoji 15 on the hanging side is rotatably connected to the prospective surface of the vertical frame 12 c by a hinge 32. 3 and 4, only one vertical frame 12 c is illustrated, but the left and right vertical frames 12 c have the same cross-sectional shape, and the other vertical frame 12 c is a shoji that serves as a suspension side on the opposite side. 15 is rotatably connected. A vertical tight material 34 is disposed on the finding surface of the vertical frame 12c to come into contact with the finding surface of the shoji 15 when the folding door 16 is closed. The vertical tight material 34 has the same structure as the above-described tight material 28.

  As shown in FIGS. 1, 3 and 4, the folding door 16 is connected to the left vertical frame 12 c, and the four shojis 15, 14, 14, and 14 are connected to each other so as to be folded in two. The four shojis 15, 14, 14, and 14 are connected to the right vertical frame 12 c and are connected to each other so that they can be folded in two. In the folding door 16, the shojis 15 at both ends are pivotally connected to the vertical frame 12c by hinges 32, respectively, so that the folding door 16 is on the hanging side. Accordingly, the two central shojis 14 and 14 are on the door-end side, and face each other when the folding door 16 is closed.

  As shown in FIG. 4, in the four shojis on the left vertical frame 12 c side, a set in which the shojis 14 and 15 are connected to each other by a connecting hinge (connecting portion) 36 and the shojis 14 and 14 are connected to the connecting hinge 36. Are connected to each other through a longitudinal bone 38. Since the four shojis on the right vertical frame 12c side have the same configuration as that on the left side, detailed description thereof is omitted.

  The shoji 14 has a configuration in which an upper rod 14a, a lower rod 14b, a vertical rod 14c, and a vertical rod 14d, which are four-round rods, and a glass plate 40 disposed inside are combined. The shoji 15 has a configuration in which an upper gutter 15a, a lower gutter 15b, a vertical gutter 15c and a vertical gutter 15d, which are four-round gutters, and a glass plate 40 arranged inside are assembled. Although the details will be described later, the glass plate 40 is disposed at a position close to the indoor side (tight material 25, 28 side) in the shojis 14, 15.

  The longitudinal bone 38 is disposed between the pair of shojis 14 and 15 and the pair of shojis 14 and 14 that are connected to each other by the connecting hinge 36 so as to be foldable in two, and rotatably connects the two sets.

The vertical bone 38 is supported between the upper frame 12 a and the lower frame 12 b and is slidable along the rail 20 and the guide rail 24. As shown in FIG. 4, the vertical rod 14 c of the adjacent shoji 14 is connected to the left and right prospective surfaces of the vertical bone 38 by a hinge 42. The vertical bones 38 are also provided at the abutting portions of the vertical saddles (door tips) 14c of the two shojis 14 at the center of the folding door 16 (see FIGS. 1 and 4). On the prospective surface of the vertical bone 38 of this abutting portion, when the vertical bones 38 and 38 are abutted with each other, an abutting tight material 44 is provided to abut against each other to ensure airtightness (see FIG. 4).

  As shown in FIG. 2, the suspension door wheel 22 is a door wheel device that supports the upper end portion of the folding door 16 by suspending it on the upper frame 12 a of the frame body 12 and guides the sliding of the shoji 14 and 15 along the rail 20.

  In the case of the present embodiment, the suspended door pulley 22 is provided on each side of the left and right prospective surfaces of each vertical bone 38 (see FIG. 4). Specifically, as shown in FIG. 2, the suspension door pulley 22 is fixed to the longitudinal bone 38 via an attachment member 47 extending vertically downward from a bridge 46 that connects the pair of rollers 22 a and 22 a, and is illustrated in FIG. 4. In this way, the rollers 22a are arranged on the left and right of the vertical bone 38. In the suspension door wheel 22, two pairs of rollers 22a and 22a arranged in parallel in the prospective direction are arranged in the longitudinal direction of the rail 20, respectively, and a guide roller 22b is arranged in the center between the left and right rollers 22a and 22a. Has been. That is, one suspension door wheel 22 has a total of four rollers 22a and one guide roller 22b. The roller 22a is rotatable about a rotation axis along the prospective direction (horizontal direction). The guide roller 22b is rotatable about a rotation axis along the vertical direction. A similar suspension door pulley 22 may be provided for all the vertical bones 38 provided in the folding door 16 (four in this embodiment as shown in FIG. 1). The number of rollers 22a may be changed. Further, the suspended door pulley 22 may be provided only on a part of the vertical bones 38.

  The guide roller 26 supports the lower end portion of the folding door 16 that slides in a suspended manner by the suspension door wheel 22, and guides the sliding of the shoji 14 and 15 along the guide rail 24. The guide rollers 26 are provided for the left and right prospective surfaces of the longitudinal bone 38, respectively. Each guide roller 26 is rotatable about a rotation axis in the vertical direction.

  FIG. 5 is a schematic view for explaining the arrangement of the shoji 14 (15) in the joinery 10 shown in FIG. 1, and is a longitudinal section schematically showing a suspension structure for the upper frame 12a of the shoji 14 by the suspension door wheel 22. FIG. In FIG. 5, in order to clearly show the suspension structure of the shoji 14 by the suspension door pulley 22, the suspension door pulley 22 that actually supports the shoji 14 to be suspended via the vertical bone 38 is directly connected to the shoji 14. This is shown as a configuration.

  As shown in FIG. 5, the shoji 14 (15) is set so that the entire center-of-gravity position A is located between the suspension fulcrum B and the tight members 25 and 28 in the prospective direction.

  Specifically, for the suspension door wheel 22 that suspends and supports the upper end of the shoji 14 with respect to the upper frame 12a, a point where a load is applied from the roller 22a to the rail 20 is referred to as a load point C. The center position of 22a, that is, the center position between the load points C and C is the suspension fulcrum B of the shoji 14. Then, in the joinery 10, the center of gravity position A of the entire shoji 14 is set closer to the tight material 25, 28 side (inside the room) than the perpendicular D passing through the suspension fulcrum B in the prospective direction.

  Moreover, among the structural members of the shoji 14, the glass plate 40 is the largest heavy article. For this reason, the gravity center position A of the shoji 14 substantially coincides with the gravity center position of the glass plate 40 or depends on the gravity center position of the glass plate 40. Therefore, in the joinery 10, the glass plate 40 is offset in the prospective direction toward the tight members 25 and 28 with respect to the respective ridges 14a to 14d (15a to 15d) of the shoji 14 (15), and the center of gravity position thereof is the hanging fulcrum B. And the tight members 25, 28. Thereby, the gravity center position A of the whole shoji 14 (15) can be easily set between the suspension fulcrum B and the tight members 25 and 28 in the prospective direction.

  Next, the operation | movement and effect | action at the time of opening / closing operation of the folding door 16 in the fitting 10 comprised as mentioned above are demonstrated.

  When opening and closing the folding door 16 in the fitting 10, for example, the handle 48 (see FIG. 1) provided on the finding surface of the vertical rod 14 d is gripped to slide the shoji 14 and 15. Then, as shown in FIG. 3 and FIG. 4, the hinges 36 connected between the shojis 14 and 15, which are foldably connected to each other, and the connecting hinges 36 between the shojis 14 and 14 move in the prospective direction, and at the same time between the longitudinal bones 38. The hinge 42 rotates. As a result, the vertical bone 38 suspended from the rail 20 of the upper frame 12a slides while being guided by the rail 20. At the same time, the shoji 14 connected to the longitudinal bone 38 by the hinge 42 slides along the rail 20, and each shoji 14, 15 also moves in the expected direction by the rotation of the connecting hinge 36.

  When opening the closed folding door 16 as shown in FIG. 1, the folding door 16 is slid while being folded in order from the side of the shoji 15 on the suspension side (see arrow X1 in FIGS. 3 and 4). As a result, the shoji 14 on the door end side other than the shoji 14 that is directly connected to the suspension-side shoji 15 and the connecting hinge 36 remains on the rail 20 in the closed position as shown in FIG. Slide along. Eventually, all the shojis 14 and 15 are folded and pulled toward the vertical frames 12c at both ends, so that the folding door 16 is fully opened (see FIG. 4).

  Further, when the opened folding door 16 is closed, the folding door 16 is slid along the rail 20 while being in a closed posture in which the folded state is released via the connecting hinge 36 in order from the door-end side shoji 14 (FIG. 3). And the arrow X2 in FIG. 4). Eventually, the folding state of all the shojis 14 and 15 is released, and the folding doors 16 are fully closed when the shojis 14 and 15 are closed in a closed posture inside the frame 12 (FIGS. 1 and FIG. 1). 3).

  Here, in the joinery 10 according to the present embodiment, as shown in FIG. 5, the center of gravity A of the shoji 14 (15) has the suspension fulcrum B of the shoji 14 (15) and the tight members 25 and 28 in the prospective direction. It is set to be located between.

  For this reason, the shojis 14 and 15 that are suspended by the rail 20 through the suspension door pulley 22 and slide are pendulums to the side (outdoor in FIG. 5) that is separated from the tight materials 25 and 28 with the suspension fulcrum B as a fulcrum. A force θ that oscillates in a shape is generated. As a result, the shojis 14 and 15 slide in a state in which their lower end portions swing in a direction away from the tight materials 25 and 28 with the suspension fulcrum B as a fulcrum. Therefore, it is avoided that a large pressing force is applied to the tight members 25 and 28 from the surface where the shojis 14 and 15 are found, and the sliding resistance between them is reduced. As a result, the operation force required to slide the shojis 14 and 15 becomes lighter, and the opening and closing operation of the folding door 16 becomes smooth. When the folding door 16 is fully closed, the prospective direction position of each of the shojis 14 and 15 is restricted, so that the finding surface is placed in contact with the tight members 25 and 28 with an appropriate pressing force.

  In particular, the joinery 10 according to the present embodiment is composed of the large folding door 16 in which one shoji 14, 15 has a weight of about 90 kg as described above. For this reason, the reduction effect of the operation force at the time of reducing the sliding resistance between the tight materials 25 and 28 and the shoji 14 and 15 becomes more remarkable. In addition, since it is prevented that the shojis 14 and 15 are strongly pressed and dragged when the shoji 14 and 15 are slid, the tight materials 25 and 28 can be prevented from being twisted or damaged. In the present embodiment, the configuration in which the tight materials 25 and 28 are provided on the upper and lower sides of the shoji 14 and 15, respectively, is exemplified. However, the tight materials 25 and 28 are described above even in a configuration in which only one of them is provided. Needless to say, effects such as reduction of sliding resistance can be obtained. In this case, the tight material 28 that contacts the lower ends of the shojis 14 and 15 is farther from the suspension fulcrum B than the tight material 25 on the upper end side, and swings in a pendulum shape with the suspension fulcrum B as a fulcrum. Since it is easily affected by the pressing force from the shoji 14 and 15, the effect of reducing the sliding resistance described above becomes more remarkable.

  As shown in FIG. 2, in the joinery 10, the upper and lower sides of the shojis 14 and 15 are guided by the guide rollers 22 b and 26 and the guide rails 18 and 24, and rattling in the expected direction is suppressed. However, the guide rollers 22b and 26 and the guide rails 18 and 24 should be arranged in consideration of the accuracy in manufacturing and assembling the shojis 14 and 15 and the frame 12 and the assembling accuracy of the shojis 14 and 15 to the frame 12. There is a gap between them that provides some design tolerance. For this reason, even if the upper and lower sides of the shojis 14 and 15 are supported by the guide rollers 22b and 26, the above-described pendulum-like swinging of the shojis 14 and 15 is sufficiently secured, and the shojis 14 and 15 and the tight material 25 are secured. , 28 is sufficiently effective in reducing sliding resistance.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  For example, in the above-described embodiment, the suspension door wheel 22 that suspends and supports the shojis 14 and 15 from the upper frame 12a is exemplified as the configuration having the pair of rollers 22a and 22a arranged in parallel in the prospective direction. You may use the suspension door pulley which has only one roller. In the case of this configuration, the load point on the rail of this one roller becomes the hanging fulcrum of the shoji.

  In the said embodiment, although the single-layer glass of 1 sheet was illustrated as the glass plate 40, in the case of the multilayer glass which bonded together two or more glass plates, the gravity center position as this whole multilayer glass is in a prospective direction. It only has to be between the hanging fulcrum of the shoji and the tight material.
