Description

Technical Field

[0001] The present invention relates to a fitting including a shoji door that opens and closes on the indoor side or the outdoor side with respect to a frame body, and a regulating mechanism that regulates the opening angle of the shoji door.

Background Art

[0002] There is known a fitting including a shoji door that is provided on a frame body and opens and closes by rotating, and a regulating mechanism that regulates the opening angle of the shoji door (see, for example, Patent Document 1). The regulating mechanism of Patent Document 1 includes a slide member that is slidably provided via a base member on the outer peripheral surface of the door end frame of the shoji door, an arm that is swingably supported at one end on the slide member, and a base member fixed to the inner peripheral surface of the frame body. A pin member provided on the tip side of the swinging arm is configured to be slidably engaged with a guide groove provided in the base member. The slide member has a slide member flat surface portion facing the base member fixed to the outer peripheral surface of the door end frame, an operation arm portion that is connected from the slide member flat surface portion to the indoor side and is provided at a substantially right angle to the slide member flat surface portion, and an operation grip portion that is fitted to the tip side of the operation arm portion so as to protrude indoors. In the regulating mechanism of this fitting, a base member, a slide member flat surface portion of the slide member, an arm, and a base member are arranged between the outer peripheral surface (prospective surface) of the door end frame and the inner peripheral surface (prospective surface) of the frame body. By extending the operation arm portion of the slide member from the outer peripheral surface of the door end frame to the indoor surface, the operation grip portion is arranged on the indoor side of the door end frame, and the operation grip portion can be operated from the indoor side with the shoji door closed. Thus, by sliding the slide member to the upper end or the lower end within the movable range, it is possible to switch between a regulated state in which the opening angle of the shoji door is regulated and a regulated release state in which the opening angle of the shoji door is not regulated.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-mentioned fitting, the operating arm portion of the slide member extends from the outer peripheral surface of the door end frame to the indoor surface. For this reason, the operating arm portion is disposed across the airtight material that is attached to the frame body and abuts against the indoor surface of the door end frame. In the portion where the operating arm portion is disposed, the airtight material is separated from the door end frame, so there is a problem that the airtightness is reduced. In addition, since a space for arranging the main part of the regulating mechanism is required between the outer peripheral surface of the door end frame and the inner peripheral surface of the frame body, there is a problem that it cannot be used for fittings with a small distance dimension between the expected surfaces of the frame body and the shoji.

[0005] An object of the present invention is to provide a fitting that can regulate the opening angle of a shoji, can be applied to fittings with a small distance dimension between the expected surfaces of the frame body and the shoji, and can prevent a decrease in airtightness.

Means for Solving the Problems

[0006] The furniture of the present invention includes a frame body, a shoji door rotatably provided with respect to the frame body so as to be openable and closable, and an opening restriction member that restricts the opening angle when the shoji door is rotated to the open side. The frame body has a frame body side indoor exposed surface that is exposed to the indoor space when the shoji door is closed, and the shoji door has a shoji door side indoor exposed surface that is exposed to the indoor space when the shoji door is closed. The opening restriction member includes a stopper body attached to either the frame body side indoor exposed surface or the shoji door side indoor exposed surface, and a receiving member attached to the other of the frame body side indoor exposed surface and the shoji door side indoor exposed surface. The stopper body is provided so as to be movable and swingable between a restriction position and a restriction release position, and includes an arm member having an engaging portion that engages with the receiving member, and an operating member that moves the arm member to the restriction position and the restriction release position. The receiving member includes an engaging groove having an open end side and a closed end side. When the shoji door is rotated to the open side with the arm member positioned at the restriction position when the shoji door is closed, as the shoji door rotates, the engaging portion is engaged with the engaging groove while the arm member swings, and the opening angle is restricted. When the shoji door is rotated to the open side with the arm member positioned at the restriction release position when the shoji door is closed, the engaging portion is positioned outside the engaging groove, and the restriction of the opening angle is released.

Advantages of the Invention

[0007] According to the present invention, it is possible to provide furniture that can restrict the opening angle of a shoji door, can be applied to furniture with a small distance dimension between each expected surface between the frame body and the shoji door, and can prevent a decrease in airtightness.

Mode for Carrying Out the Invention

[0009] [First Embodiment] Hereinafter, the fitting 1 of the first embodiment of the present invention will be described with reference to the drawings. As shown in the internal view diagram of FIG. 1, the fitting 1 of the first embodiment includes a frame body 10 attached to a wall or the like of a building, a shoji 20 that opens and closes by rotating with respect to the frame body 10, and an opening restriction member 3 that is a restriction mechanism for restricting the opening angle of the shoji 20. The fitting 1 of the present embodiment is a two-action (kip-down) window that can open and close the shoji 20 with respect to the frame body 10 in two ways: inward opening and inward tilting.

[0010] The frame body 10 is configured by joining an upper frame 11, a lower frame 12, and left and right vertical frames 13, 14 in a rectangular shape. The upper frame 11, the lower frame 12, and the vertical frames 13, 14 are made of a synthetic resin material having the same cross-sectional shape, and are framed by welding the respective ends cut at an angle of 45° with respect to the longitudinal direction.

[0011] The shoji 20 is formed by joining an upper frame 21, a lower frame 22, and left and right vertical frames 23, 24 in a rectangular shape, and holding a glass 25 disposed on the inner peripheral side thereof with the upper frame 21, the lower frame 22, the vertical frames 23, 24, and a pressing edge 26 attached thereto. The glass 25 of the present embodiment is triple glass, but may also be multilayer glass or single-pane glass. A handle 27 for operating the shoji 20 when opening and closing is provided on the vertical frame 24.

[0012] Between the frame body 10 and the shoji 20, airtightness and watertightness are ensured by airtight materials 17, 18 attached to the frame body 10 and an airtight material 28 attached to the shoji 20. The airtight material 17 is attached to a holding groove formed on the opposing surface of the frame body 10 that faces the outdoor surface of the shoji 20. The airtight material 18 is attached to a holding groove formed on the inner peripheral surface at the middle part in the expected direction of the frame body 10. The airtight material 28 is attached to a holding groove formed on the opposing surface of the outer peripheral part of the shoji 20 that faces the indoor-side finding surface of the frame body 10.

[0013] As shown in Fig. 1, when the handle 27 of the fitting 1 is directed downward (0° direction), the shoji 20 is in the fully closed state with the lock engaged. Further, as shown in Fig. 4, when the handle 27 of the fitting 1 is rotated and directed horizontally (90° direction), the lower frame 22, which is the lower end of the shoji 20, is rotatably supported with respect to the lower frame 12, and the shoji 20 is in the inwardly pivoted state where it is pivoted inward toward the interior of the room. In the inwardly pivoted state, the opening and closing angle at full open is regulated by a stay arm (not shown) provided between the upper frame 11 and the upper frame 21. Furthermore, as shown in Fig. 5, when the handle 27 of the fitting 1 is rotated and directed upward (180° direction), the vertical frame 23 is rotatably supported by the hinge 4 with respect to the left vertical frame 13 as viewed from the interior of the room, and the shoji 20 is in the inwardly opening state where it opens inward toward the interior of the room. In the inwardly opening state, the opening and closing angle of the shoji 20 at full open is regulated to approximately 90° by an arm stopper (not shown) provided between the lower frame 12 and the lower frame 22.

[0014] [Release Regulation Member] As shown in Fig. 6, the release regulation member 3 includes a receiving member 40 attached to the vertical frame 14 of the frame body 10 and a stopper main body 30 attached to the vertical frame 24 of the shoji 20. Specifically, as shown in Fig. 3, the receiving member 40 is attached to the indoor finding surface 141 on the outer peripheral side of the vertical frame 14 at a position more outward than the position where the airtight material 28 on the indoor side abuts. Further, as shown in Fig. 3, the stopper main body 30 is provided on the indoor side of the airtight material 28 on the indoor side of the vertical frame 24 and is attached to the outer peripheral surface 241 along the prospective direction. Therefore, the indoor finding surface 141 is the indoor exposed surface on the frame body side that is exposed to the indoor space when the shoji 20 is closed, and the outer peripheral surface 241 is the indoor exposed surface on the shoji side that is exposed to the indoor space when the shoji 20 is closed. Since the indoor finding surface 141 is a surface along the finding direction of the vertical frame 14 and the outer peripheral surface 241 is a surface along the prospective direction of the vertical frame 24, they are formed to be substantially orthogonal to each other when the shoji is closed.

[0015] As also shown in Fig. 7, the stopper main body 30 includes a case 31, a slide member 33, an arm member 35, a coil spring 37 which is a biasing member, and an operation button 38. The case 31 has a front surface 311 provided opposite to the receiving member 40, a back surface 312 provided parallel to the front surface 311, left and right side surfaces 313, 314 provided between the front surface 311 and the back surface 312, and a bottom surface 315, and is formed in a bottomed rectangular tube shape. An opening 316 is formed at the upper end of the case 31. An opening 317 is formed in the front surface 311 except for the upper end portion. A protrusion 318 for locking the upper end of the coil spring 37 is formed on the back surface 312. The protrusion 318 is formed above the opening 317. An arm restricting portion 321, an arm guiding portion 322, and an arm abutting portion 323 are formed on the side surfaces 313, 314. As will be described later, the arm restricting portion 321 abuts when the arm member 35 swings and restricts the swing angle. The arm guiding portion 322 guides the arm member 35 when the arm member 35 is housed in the case 31 and guides the left and right positions of the arm member 35 to predetermined positions. The arm abutting portion 323 abuts on the arm member 35 when the arm member 35 is housed in the case 31 and houses the arm member 35 along the vertical direction. Screw insertion holes 325, 326 are formed near the upper ends and lower ends of the side surfaces 313, 314. As shown in FIG. 6, the case 31 is fixed to the vertical frame 24 by screwing screws 39 inserted through the screw insertion holes 325, 326 into the outer peripheral surface 241 of the vertical frame 24.

[0016] As shown in FIG. 7, the slide member 33 includes a pair of slide plate portions 331 arranged in parallel and a connecting plate portion 332 connecting the slide plate portions 331. The connecting plate portion 332 connects the slide plate portions 331 on the lower side of the slide plate portions 331, and its lower end extends downward from the slide plate portions 331 and is further bent toward the opening 317 side of the front surface 311. This bent portion constitutes a locking portion 333 for locking the lower end of the coil spring 37. A pair of slide plate portions 331 are formed with an engagement hole 335, a long hole 336, and a shaft hole 337. The engagement hole 335 is used for engaging and fixing the operation button 38. That is, the operation button 38 is formed with a holding groove (not shown) into which the upper end of the slide plate portion 331 is inserted and a protrusion (not shown) that engages with the engagement hole 335. When the slide plate portion 331 is inserted into the holding groove, the protrusion engages with the engagement hole 335, and the operation button 38 can be fixed to the slide member 33. The long hole 336 is inserted with a screw 39 that passes through the screw insertion hole 325 of the case 31. Thereby, the slide member 33 is slidable in the vertical direction with respect to the case 31 within a range where the screw 39 abuts against the upper end and the lower end of the long hole 336. The position where the slide member 33 moves to the uppermost position is the regulated position, and the position where the slide member 33 moves to the lowermost position is the regulation release position. The shaft hole 337 is rotatably inserted with a rotation pin 352 described later.

[0017] The arm member 35 includes a pair of arms 351 arranged in parallel, a rotation pin 352 fixed to the base end portion which is one end portion of the arm 351, and an engagement pin 353 which is an engagement portion fixed to the tip end portion which is the other end portion of the arm 351. Fixing holes 354 and 355 are formed at each end portion of the arm 351. Further, a contact portion 356 that contacts the upper surface of the arm regulating portion 321 of the case 31 is formed at the base end portion of the arm 351 when the tip end portion of the arm 351 rotates toward the receiving member 40 side. The base end portion of the arm 351 is disposed outside each slide plate portion 331 of the slide member 33. A rotation pin 352 is inserted through the shaft hole 337, and the end portion of the rotation pin 352 is fixed to the fixing hole 354. Thereby, the slide member 33 is disposed between the pair of arms 351. As the rotation pin 352 rotates within the shaft hole 337, the arm member 35 is slid up and down together with the slide member 33 and is swingably attached to the slide member 33. For this reason, when the slide member 33 is in the upper position, i.e., the regulation position, the arm member 35 is also in the regulation position, and when the slide member 33 is in the lower position, i.e., the regulation release position, the arm member 35 is also in the regulation release position. The end portion of the engagement pin 353 is fixed to the fixing hole 355 at the tip end portion of the arm 351.

[0018] The coil spring 37 is a tension coil spring. The hook portion 371 on the upper end side is locked to the protrusion 318 of the case 31, and the hook portion 372 on the lower end side is locked to the locking portion 333 of the slide member 33. Thereby, the slide member 33 is biased upward by the coil spring 37, and the operation button 38 protrudes from the opening 316. Therefore, the coil spring 37 is a biasing member that biases the slide member 33 and the arm member 35 upward. Further, the coil spring 37 as this biasing member and the operation button 38 constitute an operation member that moves the slide member 33 and the arm member 35 to the regulation position and the regulation release position.

[0019] [Receiving member] As shown in FIG. 8, the receiving member 40 includes a metal base 41 and a synthetic resin guide component 45 detachably attached to the base 41. The base 41 includes a mounting portion 42 and a hook portion 43. The mounting portion 42 is formed in a substantially rectangular plate shape, and a dish hole 421, an inclined guide 422, an engagement hole 423, and a ridge portion 424 are formed therein. The dish holes 421 are formed near the upper and lower ends of the mounting portion 42. As shown in FIG. 6, screws 49 are inserted into the dish holes 421, and the base 41 is fixed to the indoor finding surface 141 of the vertical frame 14 by these screws 49. The inclined guide 422 has an inclined surface that is continuous from the surface of the mounting portion 42 and protrudes upward, and a flat surface that is continuous with the inclined surface. The engaging hole 423 is formed above the inclined guide 422. The protruding strip portion 424 is formed from above the engaging hole 423 to the base end portion of the hook portion 43, has an inclined surface that is continuous from the surface of the mounting portion 42 and protrudes upward, and a flat surface that is continuous with the inclined surface. The hook portion 43 includes a protruding portion 431 that protrudes from the surface of the mounting portion 42, and an extending portion 432 that extends downward from the tip of the protruding portion 431, and is formed in a substantially L shape in side view. An engaging piece 433 and a locking piece 434 are formed on the hook portion 43. The engaging piece 433 protrudes downward from the lower surface of the protruding portion 431. The locking piece 434 extends downward from the lower end, that is, the tip of the extending portion 432, and an engaging protrusion 435 is formed on its side surface.

[0020] The guide component 45 includes an engaging recess 451 that engages with the engaging piece 433, an extending piece portion 452 that is arranged along the extending portion 432, a guide portion 453 that is formed at the lower end of the extending piece portion 452, a holding portion 454 that is arranged along the protruding strip portion 424, and a locking piece 455 that engages with the engaging hole 423. An opening 4531 into which the engaging protrusion 435 is engaged is formed in the guide portion 453. Further, the outer surface of the guide portion 453, that is, the surface facing the stopper body 30, is an inclined surface that faces the base 41 side as it goes downward. The guide component 45 is inserted from below between the mounting portion 42 and the hook portion 43 of the base 41, engages the engaging recess 451 with the engaging piece 433, engages the engaging protrusion 435 of the locking piece 434 with the opening 4531, and engages the locking piece 455 with the engaging hole 423, thereby being attached to the base 41. In the receiving member 40, an engaging groove 456 is formed on the inner peripheral side of the guide component 45. That is, the engaging groove 456 is formed between the extending piece portion 452 and the guide portion 453 of the guide component 45, and the holding portion 454 of the guide component 45, the inclined guide 422 and the mounting portion 42 of the base 41, is a groove that is open at the lower end side (one end side) and closed at the upper end side (the other end side). Therefore, the lower end of the engaging groove 456 is continuous with the lower end of the inclined surface of the guide portion 453. The holding portion 454 is a curved plate-like portion in the guide component 45 and normally protrudes toward the extension piece portion 452 as shown in FIG. 8. Further, the lower end of the holding portion 454 is located on a substantially extended line of the flat surface of the inclined guide 422, and the holding portion 454 is inclined in a direction approaching the extension piece portion 452 as it goes upward from this lower end, and the holding portion 454 is inclined in a direction away from the extension piece portion 452 as it goes further upward. Thus, when the engagement pin 353 is inserted into the engagement groove 456 from the opened lower end side, the holding portion 454 is pushed by the engagement pin 353 and deformed. At this time, the locking piece 455 moves downward within the engagement hole 423 to allow the deformation of the holding portion 454. Then, when the engagement pin 353 gets over the holding portion 454 and is located on the closing end portion side which is the upper end of the engagement groove 456, the engagement pin 353 can be held by the holding portion 454.

[0021] [Operation of the opening restriction member] Next, the operation of the opening restriction member 3 in the fitting 1 will be described. FIG. 9 is an operation explanatory diagram for explaining the operation and movement of the opening restriction member 3. FIG. 9(A) shows a state where the shoji 20 of the fitting 1 is closed. When the shoji 20 is opened with the handle 27 rotated in the 90° direction or 180° direction from the state of FIG. 9(A), as shown in FIG. 9(B), the arm member 35 of the stopper main body 30 engages with the receiving member 40 fixed to the frame body 10, and the opening angle of the shoji 20 is restricted, resulting in a so-called semi-open state. Next, to fully open the shoji 20, as shown in FIG. 9(C), after closing the shoji 20, the operation button 38 is pressed. Then, as shown in FIG. 9(D), when the shoji 20 is opened while pressing the operation button 38, the arm member 35 is disengaged from the receiving member 40. Therefore, as shown in FIG. 9(E), the shoji 20 can be fully opened with the pressing operation of the operation button 38 released.

[0022] Figures 10 and 11 are operation explanatory diagrams for explaining the operation of the stopper body 30 of the opening restriction member 3. Figure 10(A) shows the state where the shoji 20 in Figure 9(A) is closed. The slide member 33 is pulled upward by the coil spring 37, and the operation button 38 also protrudes upward. In this state, the arm 351 of the arm member 35 abuts against the arm contact portion 323, and the engagement pin 353 is disposed in the engagement groove 456 of the receiving member 40. Figure 10(B) shows the state where the shoji 20 in Figure 9(B) is half-opened. That is, as the shoji 20 is opened, the engagement pin 353 of the arm member 35 moves upward within the engagement groove 456. At this time, the engagement pin 353 elastically deforms the holding portion 454 and gets over it and is disposed at the upper end of the engagement groove 456 and is held by the holding portion 454. Also, the contact portion 356 of the arm 351 abuts against the arm restricting portion 321, and the rotation angle of the arm 351 with respect to the case 31 and the slide member 33 is restricted. Thereby, the opening angle of the shoji 20 is restricted by the opening restriction member 3, and the shoji 20 is in a half-opened state with a smaller opening angle than the fully opened state.

[0023] Figure 10(C) shows the state where the shoji 20 in Figure 9(C) is closed and the operation button 38 is pressed. When the operation button 38 is pressed, a force greater than the biasing force of the coil spring 37 is applied to the slide member 33, and the slide member 33 moves downward to a position (restriction release position) where the screw 39 abuts against the upper end of the long hole 336. For this reason, the engagement pin 353 moves downward from the guide portion 453 and is disengaged from the engagement groove 456. Figure 11(D) shows the state where the shoji 20 is opened by pressing the operation button 38 in Figure 9(D). When the operation button 38 is pressed, since the engagement pin 353 is disengaged from the engagement groove 456, the shoji 20 can be opened with the engagement pin 353 disengaged from the receiving member 40. Figure 11(E) shows the state where the shoji 20 is opened by releasing the state of pressing the operation button 38 in Figure 9(E). When the pressing operation of the operation button 38 is released, the slide member 33 is pulled upward by the coil spring 37, and the arm member 35 also moves upward to a position (restriction position) where the screw 39 abuts against the lower end of the long hole 336.

[0024] FIG. 11(F) shows a state in which the shoji 20 is being closed. In FIG. 11(F), similar to FIG. 11(E), since the slide member 33 and the arm member 35 are moved upward by the coil spring 37, the engagement pin 353 abuts against the outer slope of the guide portion 453. When the shoji 20 is closed in this state, the engagement pin 353 moves downward along the slope of the guide portion 453. When it gets over the lower end of the guide portion 453, the engagement pin 353 is arranged in the engagement groove 456, and the arm member 35 moves upward by the coil spring 37 and returns to the state of FIG. 10(A).

[0025] The opening amount (opening angle) of the semi-open state of the shoji 20 is set by the length dimension of the arm member 35 of the opening restriction member 3 and the swing angle by abutting against the arm restriction portion 321. As shown in FIG. 12(A), when the shoji 20 is laid inward in the semi-open state, the expected dimension L1 from the indoor finding surface of the upper frame 11 to the upper edge of the indoor finding surface of the upper frame 21 is, for example, 70 mm. As shown in FIG. 12(B), when the shoji 20 is opened inward in the semi-open state, the expected dimension L2 from the indoor finding surface 141 of the vertical frame 14 to the indoor-side edge of the outer peripheral surface 241 of the vertical frame 24 is, for example, 70 mm. Although not shown, the expected dimension L1 when the shoji 20 is laid inward in the fully open state varies depending on the size of the fitting 1 and the stay arm, and is, for example, 100 mm or 167 mm. Further, when the shoji 20 is opened inward in the fully open state, as described above, the shoji 20 can be opened at an angle of 90° with respect to the frame body 10.

[0026] [Effects of the First Embodiment] According to the fitting 1 of the first embodiment, the opening angle of the shoji 20 can be restricted by the opening restriction member 3, and it can be set to a semi-open state where the opening angle is smaller than the fully open state. Then, the stopper main body 30 and the receiving member 40 of the opening restriction member 3 are attached to the indoor finding surface 141 which is the indoor exposed surface on the frame side and the outer peripheral surface 241 which is the indoor exposed surface on the shoji side. Since there is no need to arrange the opening restriction member 3 between the prospective surfaces of the vertical stile 24 and the vertical frame 14 facing each other, it can also be applied to fittings with a small distance dimension between the prospective surfaces of the frame body 10 and the shoji 20. Furthermore, since the opening restriction member 3 does not need to be arranged across the airtight material 28 on the indoor side, a decrease in airtightness can be prevented.

[0027] Since the stopper main body 30 and the receiving member 40 of the opening restriction member 3 are attached to the indoor finding surface 141 and the outer peripheral surface 241, there is a degree of freedom in the mounting height, and as in the above embodiment, it can be attached to the upper end of the vertical stile 24. Also, in the state where the shoji 20 is closed, the slide member 33 and the arm member 35 can be biased upward, that is, toward the restriction position side, by the coil spring 37 which is a biasing member, and can be set to the restricted state. For this reason, the opening restriction member 3 can be automatically set to the restricted state by closing the shoji 20, and since the restricted state cannot be released unless the operation button 38 at a high position is operated, it is possible to prevent children from inadvertently opening the shoji 20 to the fully open state.

[0028] Since the opening angle of the shoji 20 can be restricted by the opening restriction member 3, the opening amount can be set so that the semi-open shoji 20 does not protrude beyond the indoor surface of the window header. It is also possible to eliminate interference with curtains and roller screens during inward tilting or inward opening, and it is also possible to close the curtain and ventilate. Also, since the opening angle of the shoji 20 can be restricted, ventilation can be performed while suppressing rain from blowing in. Furthermore, since the opening angle of the shoji 20 can be restricted, it can be set so that children etc. cannot enter or exit during inward opening, and safety such as fall prevention can be improved.

[0029] Since the arm member 35 is provided with two arms 351, a rotation pin 352 and an engagement pin 353 installed between these arms 351, when the engagement pin 353 gets over the guide part 453 of the guide component 45 of the receiving member 40, the torsion of the arm 351 can be prevented. Therefore, the engagement pin 353 can smoothly get over the guide part 453 and can smoothly guide the engagement pin 353 into the engagement groove 456.

[0030] When the receiving member 40 is made of only a metal material, when the shoji 20 is repeatedly opened and closed, the metal engagement pin 353 and the receiving member 40 repeatedly collide with each other, resulting in scratches on the surface, increasing the sliding resistance, and increasing the shoji opening and closing force. On the contrary, in the present embodiment, since the receiving member 40 is provided with a guide component 45 made of synthetic resin, it is possible to prevent the sliding resistance between the metal engagement pin 353 and the guide component 45 from increasing, and the shoji opening and closing force can be suppressed over a long period. Since the holding part 454 for holding the engagement pin 353 is provided on the guide component 45 made of synthetic resin, even when a force to close the shoji 20 due to wind is applied at the half - open time, the arm member 35 can maintain the half - open state of the shoji 20. Further, since the guide component 45 is provided with an elastically deformable holding part 454, the function of maintaining the shoji 20 in the half - open state can be set without adding new parts, and the cost can be suppressed.

[0031] The stopper main body 30 of the opening restriction member 3 and the receiving member 40 have no left - right randomness, and since the opening restriction member 3 of the present embodiment can also be attached to the vertical frame 13 and the vertical stile 23, the price can be suppressed. Further, for the stopper main body 30 constituting the opening restriction member 3, the case 31 in which each component is arranged may be screwed to the outer peripheral surface 241 of the vertical stile 24, and for the receiving member 40, it may be screwed to the indoor finding surface 141 of the vertical frame 14. Therefore, it can be easily retrofitted to existing fixtures.

[0032] [Second Embodiment] As shown in FIGS. 13 and 14, the fitting 1B of the second embodiment includes a frame body 50, a shoji 60 that opens and closes by rotating with respect to the frame body 50, and an opening restriction member 3 that restricts the opening angle of the shoji 60. The fitting 1B of the present embodiment is an outward-opening window that can open and close the shoji 60 with respect to the frame body 50 by an outward-falling method.

[0033] The frame body 50 is configured by joining an upper frame 51, a lower frame 52, and left and right vertical frames 53, 54 in a rectangular shape. The upper frame 51, the lower frame 52, and the vertical frames 53, 54 are made of aluminum extrusion profiles. The upper frame 51 and the lower frame 52 are arranged between the upper ends and the lower ends of the vertical frames 53, 54, and are framed by screwing screws into the screw holes of the upper frame 51 and the lower frame 52 from the vertical frames 53, 54. A top latch receiver 55 is fixed to the upper frame 51.

[0034] The shoji 60 is formed by joining an upper frame 61, a lower frame 62, and left and right vertical frames 63, 64 in a rectangular shape, and holding a glass 65 arranged on the inner peripheral side thereof with the upper frame 61, the lower frame 62, the vertical frames 63, 64, and a pressing edge 66 attached thereto. The glass 65 is a multilayer glass, but it may also be triple glass or single-pane glass. A top latch 67 that is operated when opening and closing the shoji 60 is fixed to the upper frame 61. The top latch 67 includes a latch 671 that engages with the top latch receiver 55 and an operation knob 672 that projects and retracts the latch 671. A hinge 68 is attached between the lower frame 52 and the lower frame 62, and the lower frame 62 is rotatably connected to the lower frame 52. In addition, an outward-falling arm (not shown) is attached between the vertical frames 53, 54 and the vertical frames 63, 64, and the outward-falling angle in the fully open state is set by the outward-falling arm.

[0035] An airtight material 56 on the outdoor side that abuts against the upper frame 61 is attached to the upper frame 51. Further, in the upper frame 51, lower frame 52, and vertical frames 53 and 54, airtight materials 57 on the indoor side that abut against the upper frame 61, lower frame 62, and vertical frames 63 and 64 are attached to the opposing pieces 511, 521, 531, and 541 that face the indoor-facing surface of the shoji 60. Outdoor airtight materials 69 that abut against the prospective surfaces of the vertical frames 53 and 54 are attached to the vertical frames 63 and 64. A spacer 70 is fixed to the indoor surface on the upper end side of the opposing pieces 531 and 541 with screws 71. A stopper main body 30 of the opening restriction member 3 is fixed to the inner peripheral surface 72 of the spacer 70 with screws 39. Therefore, in the second embodiment, the inner peripheral surface 72 of the spacer 70 is the indoor exposed surface on the frame body side. Further, in the vertical frames 63 and 64 that face the stopper main body 30, receiving members 40 of the opening restriction member 3 are fixed with screws 49 to the indoor-facing surfaces 631 and 641 that are exposed to the indoor space, that is, on the inner peripheral side from the position where the indoor airtight material 57 abuts. Therefore, in the second embodiment, the indoor-facing surfaces 631 and 641 are the indoor exposed surfaces on the shoji side. Note that since the configurations of the stopper main body 30 and the receiving member 40 of the opening restriction member 3 are the same as those in the first embodiment, the description thereof is omitted.

[0036] Also in the fitting 1B of the second embodiment, when the shoji 60 is opened without operating the operation button 38 when the shoji 60 is closed, as shown in FIG. 15, the shoji 60 is opened in a semi-open state by the opening restriction member 3. Further, when the operation button 38 is pressed to open the shoji 60 when the shoji 60 is closed, the shoji 60 can be fully opened.

[0037] [Effects of the Second Embodiment] Also in the fitting 1B of the second embodiment, the same operational effects as those of the fitting 1 of the first embodiment can be achieved. That is, in the fitting 1B which is an outward-opening window, by restricting the opening angle of the shoji 60 with the opening restriction member 3, the shoji 60 can be opened in a semi-open state where the opening angle is smaller than the fully open state, and the same operational effects as those of the first embodiment can be achieved.

[0038] [Modification Example] The operating member is not limited to being composed of a coil spring 37, which is a biasing member, and an operation button 38. It may also be an operating member that manually moves the slide member 33 and the arm member 35 to the restricted position and the restriction release position. However, if it is provided with a biasing member such as the coil spring 37, when the shoji 20 and 60 are closed, there is an advantage that the slide member 33 and the arm member 35 can be automatically moved to the restricted position, and the release restricting member 3 can be automatically shifted to the restricted state. The operation button is not limited to being attached to the upper end of the slide member 33. A long groove extending in the vertical direction may be formed on the inner surface of the case 31, and the operation button may be exposed to the inner side of the case 31 from this long groove.

[0039] The arm member 35 is not limited to having two arms 351. A rotation pin or an engagement pin may be provided on one arm. Further, the arm of the arm member is not limited to a plate shape, and may be an angle material having an L-shaped cross section or the like. The slide member 33 is not limited to the configuration of the above-described embodiment, as long as it can slide inside the case 31 and can rotatably support the arm member 35. Furthermore, without providing a slide member, the arm member 35 may be provided so as to be slidable and swingable with respect to the case 31. For example, a groove for holding the rotation pin 352 of the arm member 35 so as to be movable in the vertical direction may be formed on the inner peripheral surface of the case 31, and the arm 351 may be configured to swing with respect to the rotation pin 352. The receiving member 40 is not limited to being composed of two parts, a metal base 41 and a synthetic resin guide part 45, and may be composed of one part. Further, the holding part 454 of the receiving member 40 is not limited to being integrally formed with the guide part 45. For example, a separate part that protrudes and retracts into the engagement groove by a spring may be used to form the holding part.

[0040] The furniture provided with the opening restriction member 3 is not limited to the above embodiments, and any furniture that can open and close a shoji door, such as a vertical sliding window, a sliding window, an inward-opening window, or a protruding window, to the indoor or outdoor side may be used. In particular, in the present invention, it is not necessary to arrange the opening restriction member 3 between the frame body and the expected surface of the shoji door, and since it does not interfere with the locking hardware arranged between the respective expected surfaces, it can be easily attached to furniture using a cam lock.

[0041] [Summary] The present invention is a furniture comprising a frame body, a shoji door provided rotatably with respect to the frame body so as to be openable and closable, and an opening restriction member for restricting an opening angle when the shoji door is rotated to the open side. The frame body has a frame-side indoor exposed surface that is exposed to the indoor space when the shoji door is closed. The shoji door has a shoji-side indoor exposed surface that is exposed to the indoor space when the shoji door is closed. The opening restriction member includes a stopper main body attached to either one of the frame-side indoor exposed surface and the shoji-side indoor exposed surface, and a receiving member attached to the other of the frame-side indoor exposed surface and the shoji-side indoor exposed surface. The stopper main body is provided so as to be movable and swingable between a restriction position and a restriction release position, and includes an arm member having an engaging portion that engages with the receiving member, and an operating member for moving the arm member between the restriction position and the restriction release position. The receiving member has an engaging groove with an open end side and a closed end side. When the shoji door is rotated to the open side with the arm member positioned at the restriction position when the shoji door is closed, as the shoji door rotates, the arm member swings and the engaging portion engages with the engaging groove to restrict the opening angle. When the shoji door is rotated to the open side with the arm member positioned at the restriction release position when the shoji door is closed, the engaging portion is positioned outside the engaging groove to release the restriction of the opening angle. According to the fitting of the present invention, the opening angle of the shoji can be restricted by the opening restriction member, and it can be set to a semi-open state where the opening angle is smaller than the fully open state. Further, the stopper body and the receiving member of the opening restriction member are attached to the indoor exposed surfaces of the frame body and the shoji, and since it is not necessary to arrange the opening restriction member between the prospective surfaces between the frame body and the shoji, it can also be applied to fittings with a small distance dimension between the prospective surfaces between the frame body and the shoji. Furthermore, since it is not necessary to arrange the opening restriction member across the airtight material, a decrease in airtightness can be prevented.

[0042] In the fitting of the present invention, the operation member includes a biasing member that biases the arm member toward the restriction position side, and an operation button that moves the arm member toward the restriction release position side. When the arm member is positioned at the restriction position by the biasing member when the shoji is closed, the engaging portion is located within the engaging groove, and when the arm member is positioned at the restriction release position by the operation of the operation button when the shoji is closed, it is preferable that the engaging portion is located outside the engaging groove. According to the fitting of the present invention, the arm member can be automatically moved toward the restriction position side by the biasing member, and the arm member can be moved toward the restriction release position side against the biasing force of the biasing member by the operation button. Therefore, when the shoji is closed, the arm member can be automatically moved to the restriction position to automatically shift the opening restriction member to the restricted state, and the restricted state cannot be released unless the operation button is operated, so it is possible to prevent children or the like from unintentionally releasing the restricted state.

[0043] In the fitting of the present invention, it is preferable that the stopper body includes a case fixed to the indoor exposed surface on the frame body side or the indoor exposed surface on the shoji side, a slide member provided slidably with respect to the case by the operation member at the restriction position and the restriction release position, and the arm member swingably attached to the slide member. According to the fitting of the present invention, since the slide member, the arm member, and the operation member can be arranged in the case of the stopper body, the stopper body can be easily attached to the existing fitting.

[0044] In the fitting of the present invention, the arm member includes two arms, a rotation pin fixed between the base end portions of the respective arms, and an engagement pin fixed between the tip end portions of the respective arms. It is preferable that the arm is swingably attached to the slide member by the rotation pin, and the engagement portion is constituted by the engagement pin. According to the fitting of the present invention, since the arm member is constituted by including two arms, a rotation pin and an engagement pin fixed between the arms, it is possible to prevent the arm member from being twisted, and the engagement pin can be smoothly guided and held in the engagement groove of the receiving member.

[0045] In the fitting of the present invention, it is preferable that the receiving member has a guide portion that guides the engagement portion into the engagement groove when the shoji is closed in a state where the arm member is located other than the regulation release position. According to the fitting of the present invention, when the shoji is closed and the arm member is located other than the regulation release position, the engagement portion can be guided into the engagement groove by the guide portion provided on the receiving member. Therefore, by closing the shoji, the engagement portion can be automatically arranged in the engagement groove, and when the shoji is opened, it can be automatically shifted to a regulated state where it is half-open.

[0046] In the fitting of the present invention, the receiving member preferably includes a metal base attached to either the indoor exposed surface on the frame side or the indoor exposed surface on the shoji side, and a synthetic resin guide component detachably attached to the base and forming the engagement groove. According to the fitting of the present invention, since the receiving member is constituted by two members, namely the base and the guide component, and the guide component forming the engagement groove is made of synthetic resin, it is possible to prevent the engagement portion of the arm member disposed in the engagement groove from being damaged, reduce the sliding resistance during shoji opening and closing, and smoothly open and close the shoji.

[0047] In the fitting of the present invention, it is preferable that the guide component has a holding portion that can hold the engagement portion on the closed other end side of the engagement groove. According to the fitting of the present invention, since the engaging portion of the arm member can be held on the closing end side of the engaging groove by the holding portion provided on the guide member, it is possible to prevent the shoji from closing due to wind when it is half-opened, and the shoji can be held in a half-opened state.
