Description

  The present invention relates to a joinery, and more particularly, to a joinery including a shoji supported by a window frame so as to be openable and an opening angle regulating means for regulating an opening angle of the shoji.

Conventionally, in a fitting such as an opening window, a vertical (horizontal) window, a protruding window, an outside window, etc., a regulating device has been proposed that regulates the opening angle of the shoji at a position opened by a predetermined angle for ventilation ( For example, see Patent Document 1).
The stay as a regulating device described in Patent Document 1 is connected to a window frame (lower frame) so that one end side thereof is freely rotatable and slidable, and the other end side is connected to a shoji (lower arm) so as to be freely disengaged. A regulating arm provided on the window frame and slidably supporting one end of the regulating arm, an operating member provided on the guide member for sliding the regulating arm, and a sliding arm provided on the shoji. An engaging frame that can be engaged with and disengaged from the pin at the other end and that can guide the pin is configured. In this stay, by operating the operating member in a state where the shoji is closed and sliding one end of the restricting arm to the half-open (ventilation) position, the pin on the other end of the restricting arm is engaged with the engagement frame, If the shoji is opened in this state, the opening angle of the shoji is regulated by the regulating arm. On the other hand, by sliding one end of the restricting arm to the fully open position with the shoji closed, the other end of the pin is removed from the engagement frame, and if the shoji is opened in this state, the restricting arm is restricted. The shoji can be fully opened. Further, the stay described in Patent Document 1 includes a lock pin that moves in conjunction with the slide of the restriction arm, and a lock frame that is fixed to the shoji so as to be engageable with the lock pin. By sliding the restricting arm to the lock position, the lock pin and the lock frame engage with each other so that the shoji can be locked so that it cannot be opened.

  However, in the conventional restriction device, it is difficult for the user to determine whether the operation member is in the half-open position, the full-open position, or the lock position, and an erroneous operation may be caused. That is, if the shoji is opened assuming that the operating member is in the half-open position even though the operating member is in the fully open position, the shoji may be opened too far against the user's intention, or the operating member is in the restricted position. If you open the shoji screen as if it is in the fully open position, there will be inconveniences in use due to inconveniences such as the restricting arm restricting the opening of the shoji and applying a strong impact to the regulating device. Met. In particular, in the conventional regulating device, since the fully open position is provided between the lock position and the half open position, when the lock is released and the operation member is operated to the half open position, the fully open position is passed. Thus, an erroneous operation is likely to occur in the fully open position before moving to the half open position.

  An object of the present invention is to provide a joinery having an opening angle regulating means that can prevent erroneous operation and improve convenience.

  The joinery of the present invention is a joinery comprising a window frame, a shoji supported by the window frame so as to be openable, and an opening angle regulating means for regulating the shoji to a predetermined opening angle, wherein the opening angle regulation is performed. The means includes a sliding member provided slidably on one of the window frame and the shoji, an engaging portion provided on the other of the window frame and the shoji, and one end of the engaging portion being engaged and disengaged. An angle-regulating arm that is connected to the slide member so that the other end of the slide member is rotatably connected to the slide member, an operation member that is exposed to the indoor side to slide the slide member, and the slide In a state where the movement restricting means is provided so as to be movable between a restriction position for restricting the sliding movement of the member and a release position for releasing the restriction, and the movement restricting means is moved to the release position. , Said operation By sliding the slide member by operating a member, an open angle restricted state in which the angle restricting arm is connected to the engaging portion, and an open angle unrestricted state in which the connection between the angle restricting arm and the engaging portion is released Is configured to be switchable, and in a state where the movement restricting unit is moved to the restricting position, the sliding movement of the slide member is restricted, so that the angle restricting arm is connected to the engaging portion. Is maintained.

  Here, as the joinery of the present invention, it is only necessary that the shoji is supported so as to be able to open and close, and any opening type such as an open window, a vertical (horizontal) shed window, a protruding window, an outside window, etc. Applicable to windows. Further, the slide member and the operation member to which one end of the angle restricting arm in the opening angle restricting means is connected may be provided on the window frame side or may be provided on the shoji side.

  According to the present invention described above, the sliding movement of the sliding member is restricted by moving the movement restricting means to the restricting position, and the open angle restricting state is maintained, so that the shoji is fully opened in an attempt to be half open. Can be prevented. Therefore, when there is a possibility that a user unfamiliar with the opening / closing operation (for example, a child or an elderly person) may operate the operating member by operating the operating member by placing the movement restricting means at the restricting position. The sliding member is not slid to a position where it can be fully opened, and the shoji can be prevented from opening more than half-opened, so that the situation where the shoji opens too much unintentionally can be prevented. On the other hand, by moving the movement restricting means to the release position at the user's discretion, the opening angle restricted state and the opening angle non-restricted state can be switched by operating the operation member. Or open the door fully to clean the outdoor surface of the shoji.

At this time, in the joinery of the present invention, the slide member is slidably supported by a base member fixed to one of the window frame and the shoji, and the movement restricting means includes the slide member and the base member. The restriction position that is in contact with the other of the slide member and the base member is changed by changing the screwing state of the screwing restriction member. A configuration in which the release position can be switched can be adopted.

The restriction position, which is composed of a slide restriction member that is slidably supported on one side so as to cross the slide direction of the slide member, and that contacts the other of the slide member and the base member by sliding the slide restriction member; The release position from which the contact is released may be switchable.

  According to each configuration described above, the slide member slides with respect to the base member fixed to one of the window frame and the shoji by the movement restricting means constituted by any one of the screw restricting member, the rotation restricting member, and the slide restricting member. By restricting the movement, the slide member can be surely positioned at the restriction position and the open angle restriction state can be maintained. That is, by providing a base member that slides and supports the slide member, for example, compared to the case where the slide member is supported by a frame material of a window frame or a shoji collar, the processing accuracy of parts such as the slide member and the base member is improved. Assembly accuracy can be improved, and rattling between components can be prevented, and position accuracy in an open angle restricted state or an open angle unrestricted state can be improved.

In the joinery of the present invention, it is preferable that the movement restricting means is provided at a position hidden from the indoor side by the shoji when the shoji is closed.
According to such a configuration, an operation that erroneously moves the movement restricting means to the release position can be prevented, and an erroneous operation can be prevented more reliably and convenience can be further improved.

As described above, in the joinery of the present invention, an engagement pin projecting toward the other of the window frame and the shoji is provided at one end portion of the angle regulating arm, and the engagement portion is engaged with the engagement pin. And a guide groove capable of slidingly guiding the engaging pin and a groove opening having an opening at one end of the guide groove are formed, and the engaging pin is separated from the guide groove through the groove opening. It is possible to adopt a configuration in which the open angle non-regulated state is configured by deviating.

An operation knob 26 serving as an operation member is fixed. The base member 23 is screwed with a screw 27 as a screwing restricting member for restricting the sliding movement of the slide member 24. The screw 27 may be operable with a tool such as a screwdriver, or may have a head having a head that can be operated by a user's hand or a knob.

  The receiving member 22 is formed by bending a metal plate material, and includes a guide groove 221 that extends vertically and a groove opening 222 in which a lower end portion of the guide groove 221 is opened. An engagement pin 252 at the tip (one end) of an angle regulating arm 25 described later is inserted into the guide groove 221, and the engagement pin 252 is guided by the guide groove 221 as shown in FIG. 5. At the same time, the guide groove 221 and the engagement pin 252 engage with each other, so that the opening angle of the shoji 6 is restricted by the angle restricting arm 25 (opening angle restricting state). On the other hand, as shown in FIG. 6, the engagement pin 252 is removed from the guide groove 221 through the groove opening 222, so that the shoji 6 can be fully opened without restricting the opening angle (open angle non-opening). Regulated state).

  As shown in FIG. 7, the base member 23 of the apparatus main body 21 is formed from a metal plate by bending, and a support surface portion 231 that slides and supports the base end piece portion 241 of the slide member 24, and more than the support surface portion 231. An arm receiving portion 232 that protrudes and receives the angle regulating arm 25 is configured. The support surface portion 231 has two linear slide long holes 233 for sliding and guiding the slide member 24 and a bent shape for guiding a guide pin 253 provided on the base end (other end) side of the angle regulating arm 25. At least a guide elongated hole 234 and a screw hole 235 into which the screw 27 is screwed are formed. Then, pins 241A are inserted into the slide long holes 233 from the side opposite to the slide member 24, and the tips of these pins 241A are coupled to the slide members 24, so that the slide members 24 are moved along the slide long holes 233. The slide is guided. The guide slot 234 is formed to have an arcuate half-open guide portion 234A that guides the guide pin 253 when the shoji 6 is half-opened, and a fully-open guide portion 234B that guides the guide pin 253 to the fully-open position. The angle restricting arm 25 is guided according to the slide position of the member 24.

  As shown in FIG. 7, the angle regulating arm 25 slides on an arm body 251 formed of an overall long metal plate and a base end (other end) on the side of the apparatus body 21 of the arm body 251. The shaft support pin 254 is rotatably connected to the member 24, and the biasing spring 255 is interposed between the head of the shaft support pin 254 and the arm main body 251. The guide pin 253 is fixed at a position eccentric from the pivot pin 254 on the base end side of the arm main body 251, and the engagement portion 22 is connected to the distal end portion (one end portion) on the receiving member 22 side of the arm main body 251. The coupling pin 252 is fixed. Such an angle restricting arm 25 is located with respect to the slide member 24 around the shaft support pin 254 in a state where the guide pin 253 is positioned at the half-open guide portion 234A in the guide long hole 234 of the base member 23 (open angle restricting state). In this state, the engagement pin 252 can be engaged with the guide groove 221 of the receiving member 22. On the other hand, the angle restricting arm 25 is locked so as not to rotate in a state where the guide pin 253 is positioned at the fully open guide portion 234B (open angle non-restricted state), and in this state, the engagement pin 252 is received by the receiving member. It is configured to be separated from the guide groove 221 through the 22 groove openings 222.

  As described above, the slide member 24 is formed to have the base end piece portion 241 and the extended piece portion 242, and as shown in FIGS. 4 and 8, the base end piece portion 241 includes the base member 23. An arcuate guide hole 243 that overlaps the half-open guide portion 234A and a notch portion 244 that is notched so as to surround the head of the screw 27 are formed. This notch 244 is a position that can be engaged with the head of the screw 27 in a state where the slide member 24 is slid upward (open angle restricted state), as indicated by a virtual line (dashed line) in FIG. In this state, the screw 27 is fastened to the base member 23, that is, the screw 27 is moved to the restriction position, so that the notch 244 is locked to the screw 27 so that the sliding movement of the slide member 24 is restricted. It has become. On the other hand, as shown by a solid line in FIG. 8, by loosening the screw 27, that is, by moving the screw 27 to the release position, the locking of the notch 244 by the screw 27 is released and the slide member 24 slides downward. It can be done.

  That is, the position where the screw 27 is tightened until the gap between the head of the screw 27 and the support surface 231 of the base member 23 becomes smaller than the thickness of the base end piece 241 of the slide member 24 is the restricted position. Yes, by moving the screw 27 to this restriction position, the head of the screw 27 and the notch 244 of the slide member 24 are in contact with each other. On the other hand, the position where the screw 27 is loosened to the position where the gap dimension between the head of the screw 27 and the support surface portion 231 of the base member 23 becomes larger than the thickness dimension of the base end piece 241 of the slide member 24 is the release position. Yes, by moving the screw 27 to this release position, the notch portion 244 of the slide member 24 can pass through the gap between the head of the screw 27 and the support surface portion 231. As described above, the movement restricting means of the present embodiment is configured by the screw 27 that abuts the notch 244 and restricts the slide movement of the slide member 24 or releases the restriction.

  In the above opening angle restricting device 20, the sliding pin 24 is restricted from sliding downward while the screw 27 is in the restricting position, whereby the engaging pin 252 of the angle restricting arm 25 guides the receiving member 22. The open angle restriction state engaged with the groove 221 is maintained, and the shoji 6 can be opened only to the half-open state. Further, when the screw 27 is moved to the release position, the guide pin 253 of the angle restricting arm 25 is positioned at the fully open guide portion 234B in the guide long hole 234 of the base member 23 by sliding the slide member 24 downward. The engagement pin 252 of the angle restricting arm 25 is configured to be detached from the guide groove 221 of the receiving member 22. Since the sliding movement of the slide member 24 is not restricted in the state where the screw 27 is in the release position as described above, the opening angle restricted state and the opening angle non-restricted state are switched.

The movement restricting means in the present embodiment is not limited to the screw 27 as the screwing restricting member described above, but may be a rotation restricting member having a form as shown in FIG.
In FIG. 9, the base piece 241 of the slide member 24 is formed with a rising piece 245 that rises in a direction away from the support surface 231 of the base member 23. A locking piece 28 is attached to the rising piece 245 as a rotation restricting member that is pivotally supported by a rotary shaft 281 on a rotary shaft along the sliding direction of the slide member 24. As shown by a solid line in FIG. 9, the locking piece 28 locks the end edge of the support surface portion 231 by rotating its tip toward the base member 23 side (regulatory position), and FIG. As indicated by a two-dot chain line), it is configured to release the lock (release position) by rotating it away from the base member 23. Accordingly, when the locking piece 28 is in the restricted position, the sliding movement of the slide member 24 is restricted and the open angle restricted state is maintained, and when the locking piece 28 is in the released position, the slide member 24 is slid. It becomes possible to switch between the open angle restricted state and the open angle unrestricted state.

According to this embodiment, there are the following effects.
(1) If the screw 27 or the locking piece 28 is moved to the release position, the opening angle restricted state and the opening angle non-restricted state can be switched, and the opening angle desired by the user (half open or fully open) can be obtained. The shoji 6 can be opened, and convenience can be improved. On the other hand, if the screw 27 and the locking piece 28 are moved to the restricting position, the shoji 6 can be opened only to a half-open opening angle. Therefore, it is possible to prevent a misoperation such that the shoji 6 is unintentionally opened too much and the operation is performed by misunderstanding that the opening angle is restricted despite the opening angle non-restricting state. It is also possible to prevent the user from operating the operation knob 26 to the fully open side unexpectedly.

(2) Further, since the screw 27 and the locking piece 28 are provided at positions where the base member 23 and the slide member 24 are locked to each other, the screw 27 and the locking piece 28 are in a state where the shoji 6 is closed. Since they are concealed from both the indoor side and the outdoor side and cannot be operated, erroneous operations can be prevented more reliably. On the other hand, if the shoji 6 is opened, the screw 27 and the locking piece 28 can be operated. Therefore, the operation for switching between the restriction position and the release position is not complicated, and the convenience can be improved.

(3) Further, the screws 27 and the locking pieces 28 can be used as the movement restricting means for the slide member 24. Even when the structure of the movement restricting means is changed, it is necessary to greatly change the structures of the apparatus main body 21 and the receiving member 22. Therefore, the optimum movement restricting means can be selected according to the opening / closing type of the window, the mounting position of the opening angle restricting device 20, and the like. Accordingly, the movement restricting means is appropriately selected depending on the sliding direction (up and down, left and right) of the slide member 24, the mounting position of the apparatus main body 21 (the vertical frame 4, the lower frame 3, the vertical rod 9, the lower rod 8, etc.), and the like. It is possible to secure functions and improve convenience, such as making it difficult to automatically move from the restriction position to the release position due to vibration or the like, or making it easy to switch between the restriction position and the release position.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
FIG. 10 is an exploded perspective view showing the opening angle regulating device 30 according to the second embodiment. FIG. 11 is a side view showing the opening angle regulating device 30. 12 and 13 are diagrams for explaining the operation of the opening angle regulating device 30.
In the present embodiment, the opening angle restriction device 30 is attached to the same window as the vertical window 1 and has substantially the same basic configuration as the opening angle restriction device 20 of the first embodiment. The configurations of the angle restricting arm, the receiving member, and the movement restricting means are different from those of the first embodiment. Hereinafter, the differences will be described in detail.

  The opening angle regulating device 30 includes a device main body 31 provided in the vertical frame and a receiving member 32 as an engaging portion fixed to the vertical saddle of the shoji, and the device main body 31 is fixed to the prospective surface of the vertical frame. A base member 33, a slide member 34 supported by the base member 33 so as to be vertically slidable, and an angle regulating arm 35 pivotally supported by the slide member 34. As shown in FIG. 10, the slide member 34 includes a base end piece 341 that is slidably supported by the base member 33, and an extended piece 342 that extends from the base end piece 341 into the room. The base end piece portion 341 and the extended piece portion 342 are separately configured and coupled, and an operation knob 36 as an operation member is fixed to the extended piece portion 342. Further, the base member 33 is provided with an advance / retreat piece 37 as a slide restricting member for restricting the slide movement of the slide member 34.

  The receiving member 32 includes a fixed piece 321 fixed to the vertical hook and an engagement pin 322 fixed to the fixed piece 321 and protruding to the vertical frame side. The angle restricting arm 35 is pivoted to a slide member 34 by an arm body 351 made of a metal plate material that is bent in an overall long shape, and a base end portion (the other end portion) on the apparatus body 31 side of the arm body 351. The shaft support pin 354 is connected freely, and the biasing spring 355 is inserted between the arm main body 351 and the slide member 34 through which the shaft support pin 354 is inserted. A guide pin 353 is fixed at a position eccentric from the pivot pin 354 on the base end side of the arm main body 351. In addition, a guide groove 356 that extends and bends substantially vertically and a groove opening 357 in which an upper end portion of the guide groove 356 is opened are formed on the distal end side (the other end side) of the arm main body 351. The guide pin 322 of the receiving member 32 is inserted into the guide groove 356. As shown in FIG. 11, the guide pin 322 is guided by the guide groove 356 and is engaged with the guide groove 356. When the joint pin 322 is engaged, the opening angle of the shoji is restricted by the angle restricting arm 35 (opening angle restricting state). On the other hand, the engagement pin 322 is removed from the guide groove 356 via the groove opening 357, so that the shoji can be fully opened without restricting the opening angle (opening angle unregulated state).

  The base member 33 is formed to have a support surface portion 331 for slidingly supporting the base end piece portion 341 of the slide member 34, and the support surface portion 331 has two linear slide lengths for slidingly guiding the slide member 34. A hole 333 and a bent guide long hole 334 for guiding the guide pin 353 of the angle restricting arm 35 are formed. Then, pins 341A are inserted into the slide long hole 333 from the opposite side to the slide member 34, and the tip of these pins 341A is coupled to the slide member 34, so that the slide member 34 is moved along the slide long hole 333. The slide is guided. On the other hand, the base end piece portion 341 of the slide member 34 is formed with an arc-shaped guide long hole 343 that guides the guide pin 353 and an arm receiving portion 346 that protrudes toward the vertical shaft side and receives the angle restricting arm 35. Yes. Such a slide member 34 moves an advance / retreat piece 37 (described later) to a restriction position, whereby a guide pin 353 of the angle restriction arm 35 is locked to the advance / retreat piece 37 and the slide movement is restricted. Since the engagement between the guide groove 356 and the engagement pin 322 is maintained, the open angle restriction state is configured. On the other hand, by moving the advance / retreat piece 37 to the release position, the locking of the guide pin 353 is released, and the slide member 34 can be slid downward. Thus, by sliding the slide member 34 downward, the engagement pin 322 is disengaged from the guide groove 356 of the angle restriction arm 35, and the open angle non-restricted state is configured.

  The advance / retreat piece 37 is supported by the base member 33 so as to be movable back and forth between the restriction position shown in FIG. 12 and the release position shown in FIG. The advancing / retreating piece 37 includes a sliding surface portion 371 along the back surface of the support surface portion 331 of the base member 33, a bent curved surface portion 372 that is bent from the sliding surface portion 371 and extends away from the back surface of the supporting surface portion 331 by a predetermined distance. An operation surface portion 373 extending to the surface side of the support surface portion 331 is formed continuously with the portion 372. Long holes 374 and 375 extending perpendicularly to the sliding direction of the slide member 34 are formed in the sliding surface portion 371 and the folding surface portion 372, respectively, and pins 376 and 377 inserted through these long holes 374 and 375, respectively. Are coupled to the support surface portion 331. A long washer 377A through which the pin 377 is inserted is inserted between the bent surface portion 372 and the support surface portion 331, so that a separation distance between the bent surface portion 372 and the support surface portion 331 is secured. Yes.

  As shown in FIG. 12, such advancing / retreating piece 37 is slid in a direction in which the operation surface portion 373 is separated from the support surface portion 331, so that a part of the sliding surface portion 371 overlaps the back side of the guide long hole 334. It is moved to a restricting position where it can come into contact with the guide pin 353. When the advancement / retraction piece 37 is moved to this restriction position, the guide pin 353 comes into contact with the sliding surface portion 371 and the slide movement of the slide member 34 and the angle restriction arm 35 is restricted, thereby maintaining the open angle restriction state. It has become so. On the other hand, as shown in FIG. 13, when the operation surface portion 373 is slid in the direction approaching the support surface portion 331, the folding surface portion 372 overlaps with the back side of the guide long hole 334 and does not contact the guide pin 353. It is moved to the release position where the restriction by the contact of the sliding surface portion 371 is released. By moving the advancing / retreating piece 37 to this release position, the guide pin 353 can move along the guide long hole 334 without contacting the sliding surface portion 371, and the slide member 34 and the angle restricting arm 35 are restricted. Is released, thereby switching between the open angle restricted state and the open angle unrestricted state.

  Further, in the above-described embodiment, the screw 27 as the screwing restricting member, the locking piece 28 as the rotation restricting member, and the advance / retreat piece 37 as the slide restricting member have been described as the movement restricting means. Not limited to this, any configuration can be adopted as the movement restricting means. For example, instead of the screwing restriction member (screw 27), a push button type restriction member may be used. In this case, if the button provided on the base member protrudes to contact the slide member, the slide of the slide member can be regulated, and the slide member does not contact by pressing the button. If you do, you will be able to lift the regulations. Furthermore, the restriction member may be a simple pin, and in this case, the slide of the slide member can be restricted by passing the pin through both the slide member and the base member. The regulation can be lifted by removing.

In addition, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the invention has been illustrated and described with particular reference to certain specific embodiments, but without departing from the spirit and scope of the invention, Various modifications can be made by those skilled in the art in terms of material, quantity, and other detailed configurations.
