  The present invention relates to a window device with a screen door self-propelled prevention device provided with a self-propelled device for preventing the screen door built in such a manner that it can move horizontally with respect to the window frame when the wind is strong. Regarding improvements.

  Conventionally, as a window device for opening and closing the window opening of various buildings, a sliding door type window device that horizontally moves a sliding door shoji built in a window frame in the width direction of the window frame is widely known. Yes. In addition, for the purpose of ensuring ventilation while preventing insects from entering, it is also common to build a screen door on the outdoor side of a sliding door shoji built in a window frame.

  A conventionally used screen door is a lightweight door made by attaching a synthetic resin or metal screen to an aluminum alloy screen door frame. For this reason, a large force is not required for movement in the opening and closing direction. In recent years, the screen door can be moved with a smaller force, for example, by providing a door cart that can run on the lower guide rail for the screen door formed on the lower frame of the window frame on the lower arm that forms the lower side of the screen door. Various structures are also used to make it.

  However, as described above, since the screen door does not require a large force to move, the burden on the person who opens and closes the screen door can be reduced. However, when a force in the opening and closing direction acts on the screen door in a strong wind, the screen door There is a possibility of moving (self-propelled) without permission. For example, when a typhoon approaches or a high-rise building such as a high-rise apartment, such a problem is likely to occur.

  In view of such circumstances, for example, Patent Document 1 proposes to provide a self-propelling device for a screen door between the window frame and the screen door in order to prevent the screen door from self-running. 16-17 has shown the window apparatus 1 with the screen door self-propelled prevention apparatus of the conventional structure substantially the same as what was described in patent document 1. FIG. This window device 1 includes a window frame 2, a pair of sliding door shojis 3 and inner shojis 4, a screen door 5, and a self-running prevention device 6.

  Of these, the outer shoji 3 and the inner shoji 4 are built in the window frame 2 so as to be horizontally movable in the width direction of the window frame 2 (left and right direction in FIG. 16). The screen door 5 is built in the window frame 2 so that it can move horizontally in the width direction of the window frame 2 in the outdoor side portion of the window frame 2 in which the outer shoji 3 and the inner shoji 4 are built. It is included. The self-running prevention device 6 includes a locking tool 7 and a receiving tool 8. Among these, the locking tool 7 is fixed to one vertical rod 9b among the pair of vertical rods 9a, 9b constituting the screen door 5. On the other hand, among the pair of vertical frames 10a and 10b constituting the window frame 2, the receiver 8 is provided on the same side as the one vertical rod 9b in the width direction of the window frame 2. Are fixed to the vertical frame 10b.

  The locking device 7 includes an operation unit 11 and a locking piece 12. Among these, the operation part 11 is provided in the state exposed to the outdoor side surface of said one vertical shaft 9b. The locking piece 12 is formed by bending a metal plate into a substantially L shape. And it is comprised so that this locking piece 12 can be slid to an up-down direction by operating the operation part 11 among these to an up-down direction.

  The receiver 8 is composed of a mounting seat 13 and a receiving piece 14 bent in a substantially U shape. The mounting seat 13 includes a pair of mounting holes 15 and 15 which are through holes. Is formed. The receiving device 8 having such a configuration is screwed and fixed to one vertical frame 10b constituting the window frame 2 by using a mounting screw (not shown) inserted through the mounting holes 15 and 15. Yes.

  In the case of the conventional window device 1 having the above-described configuration, in order to prevent the screen door 5 from self-propelling, the screen door 5 is connected to one vertical rod 9b of the screen door 5 and to the one of the window frame 2. After moving to the closed position where it abuts the vertical frame 10b, the operation unit 11 is operated in the vertical direction. Thereby, the locking piece 12 is moved in the vertical direction, and the locking piece 12 and the receiving piece 14 are engaged with each other in the width direction of the window frame 2. Therefore, according to the window device 1, the screen door 5 is moved (self-propelled) from the closed position to the opening direction by the engagement of the locking piece 12 and the receiving piece 14 even in a strong wind. You can prevent things.

  However, in the case of the window device 1 having a conventional structure, in order to prevent the screen door 5 from self-propelling, it is necessary to operate the operation unit 11 from the outdoor side after moving the screen door 5 to the closed position. is there. For this reason, the operator who operates this operation part 11 needs to go outdoors, such as a veranda. For example, when it is necessary to move the screen door 5 in the opening direction for cleaning work, the operation unit 11 is operated to temporarily engage the locking piece 12 and the receiving piece 14. It is necessary to cancel. After the cleaning work is completed, it is necessary to operate the operation unit 11 again. Therefore, there is a possibility that the operation unit 11 may be forgotten (forgotten to be locked). As described above, in the case of the window device 1 having a conventional structure, there is a problem that workability for preventing the screen door 5 from being self-propelled is poor and that it is easy to forget to lock. Furthermore, when the self-propelled prevention device 6 is installed on an existing window, it is necessary to attach the receiver 8 to the window frame 2 fixed to the opening of the building. For this reason, there also exists a problem that the burden to the resident at the time of construction tends to become large.

  The rotating locking piece 41 is formed by punching a metal plate such as a stainless steel plate into a predetermined shape and bending it, and as shown in FIG. 11, the whole is configured in a substantially L shape (saddle shape). When the screen door side locking device 38 is attached, an operation from the indoor side (inside the room) is possible, and the screen is rotated based on this operation. The rotating locking piece 41 includes a flat base half 50 and a tip half 51 bent into a substantially U shape, and the tip (a part of the tip half 51) has the above-mentioned part. A locking plate portion 52 that is bent in a direction substantially perpendicular to the base half portion 50 is provided. The locking plate 52 is formed on both sides in the width direction of the rotating locking piece 41 (front and back directions in FIGS. 11A and 11F, FIGS. 11B and 11C). ) In the left-right direction} is curved in a direction away from the base half 50. Further, the base half portion 50 is formed with a through hole 53 for inserting a pivot 54 described later.

  The rotating locking piece 41 having the above-described configuration is supported by the case portion 40 so as to be rotatable (swingable) using a pivot 54 as shown in FIG. Specifically, a small-diameter columnar tip of the pivot 54 is inserted in a through hole 53 formed in the base half portion 50 of the pivot locking piece 41 in a state where the axial intermediate portion of the pivot 54 is loosely inserted. The portion 55 is fitted in the support hole 45a formed in the one side plate portion 42a, and the partially conical columnar base end portion 56 of the pivot 54 is connected to the support hole formed in the other side plate portion 42b. 45b is fitted internally. Further, in order to prevent the pivot 54 from coming out of the case portion 40, caulking is applied. Further, in the case of this example, around the intermediate portion in the axial direction of the pivot shaft 54, between the both side surfaces of the base half portion 50 of the rotating locking piece 41 and the inner side surfaces of the both side plate portions 42a and 42b, Ring-shaped washers 57 and 57 are provided, respectively.

  Therefore, the rotation locking piece 41 is supported in the case portion 40 so as to be rotatable around the pivot 54. In the case of this example, the rotation range of the rotation locking piece 41 is restricted from the unlock position shown in FIG. 14A to the range of the lock position shown in FIG. Yes. First, in order to prevent the rotation locking piece 41 from rotating counterclockwise from the unlock position, a rotation stopper (not shown) is provided on the rotation locking piece 41 or a part of the case portion 40. Provided. As a result, the rotation locking piece 41 is in a direction in which it is retracted from the opening 46 from the unlocked position arranged substantially parallel to the both side plate portions 42a, 42b (vertically in the attached state). Prevents clockwise rotation. Further, in order to prevent the rotation locking piece 41 from rotating clockwise from the lock position, one end portion in the width direction of the base half portion 50 constituting the rotation locking piece 41 is formed on the notch 48. It is engaged with the groove bottom. Thereby, the rotation locking piece 41 is prevented from rotating clockwise from a lock position arranged in a substantially right angle direction (horizontal direction in the attached state) with respect to the both side plate portions 42a and 42b. . Therefore, in the case of this example, the rotation locking piece 41 can rotate approximately 90 degrees.

  In the case of this example, the screen door side locking device 38 having the above-described configuration is used to connect the screen door 17 with respect to the width direction of the window frame 16 of the pair of vertical rods 32a and 32b constituting the screen door 19. It is supported and fixed to one vertical rod 32a provided on the same side as the door rod 26a (the right side in FIG. 1, the left side in FIGS. 2 and 5). For this purpose, a screen door side opening 59 is formed in the vertical middle portion (central portion) of the indoor side wall 58 constituting this one vertical wall 32a. A pair of through holes 60a and 60b are formed. The vertical dimension of the screen door opening 59 is set to be equal to or slightly larger than the sum of the vertical dimensions of the opening 46 and the notch 48 formed in the case 40. The pitch between the two through holes 60 a and 60 b is equal to the pitch between the pair of mounting holes 49 a and 49 b formed in the connecting plate portion 43 constituting the case portion 40. In the case of this example, in the state where the screen door side locking device 38 is arranged inside the vertical intermediate portion of the one vertical rod 32a, mounting screws (flat screws) inserted through the through holes 60a, 60b. 61a and 61b are screwed into the mounting holes 49a and 49b and further tightened. Thereby, the said screen door side locking tool 38 is screwed and fixed with respect to the said one vertical rod 32a.

In the case of this example having the above-described configuration, the rotating locking piece 41 is inserted by inserting a finger from the indoor side through the screen door side opening 59 formed in the indoor side wall 58 of the one vertical wall 32a. It can be rotated. In addition, although illustration is abbreviate | omitted, an operation part may be provided adjacent to the up-down direction of the screen door side locking tool 38, and operation (for example, up-down slide) and rotation of the rotation locking piece 41 may be linked. . Then, by rotating the rotating locking piece 41 from the unlock position to the locking position, the leading half 51 constituting the rotating locking piece 41 is projected to the indoor side from the indoor side wall 58. I can do things.
In this example, the screen door side locking device 38 is screwed to the one vertical rod 32a using a pair of mounting holes 49a and 49b provided in the connecting plate portion 43 constituting the case portion 40. Although fixed, for example, the screen door side locking device 38 can be screwed and fixed using preliminary mounting holes 44 a and 44 b formed in the side plate portions 42 a and 42 b constituting the case portion 40. As in this example, in the case of fixing using the attachment holes 49a and 49b of the connecting plate portion 43, the preliminary attachment holes 44a and 44b may be omitted.

  On the other hand, the shoji-side support 39 is formed by punching a metal plate such as a stainless steel plate into a predetermined shape and bending it, and as shown in FIG. It comprises a receiving piece 63 which is bent at a substantially right angle from one end of the mounting seat 62 (outdoor side end in the mounted state). The mounting seat 62 is formed with a pair of mounting holes 64a and 64b spaced apart in the length direction (vertical direction in the mounted state). The receiving piece 63 includes a receiving piece main body 65 provided in a state of being continuous with one end of the mounting seat 62, and both longitudinal ends of the receiving piece main body 65 (upper and lower ends in the attached state). ) To the mounting seat portion 62, and a pair of guide portions 66a and 66b bent substantially at right angles. Further, the distance between the inner surfaces of the guide portions 66a and 66b is set to be slightly larger than the width dimension of the front half portion 51 (locking plate portion 52) constituting the rotary locking piece 41.

  In the case of this example, the said shoji side support 39 which has the above structures is fixed to the outdoor side part of an up-down direction intermediate part (center part) among the door-end fences 26a which comprise the said shoji 17. Yes. For this purpose, a pair of screw holes 68 are formed in the prospective wall 67 constituting the outdoor side wall of the door toe 26a. The pitch of both the screw holes 68 is equal to the pitch of the pair of mounting holes 64a and 64b provided in the shoji side support 39. In the case of this example, both the mounting holes 64a and 64b were inserted in a state where the shoji-side support 39 was placed on the outdoor side portion of the door toe 26a and the receiving piece 63 was placed on the outdoor side. Mounting screws (flat screws) 69a and 69b are screwed into the screw holes 68 and further tightened. Thereby, the said shoji side receiving tool 39 is screwed and fixed to the expectation wall 67 of the door-end rod 26a which comprises the said outer shoji 17. Further, in the case of this example, the fixing position of the shoji-side support 39 is determined in consideration of the mounting position of the screen door-side locking tool 38 in the vertical direction and the protruding amount of the rotating locking piece 41 from the indoor side wall 58. Has been decided. In addition, although illustration is abbreviate | omitted, you may enable it to adjust finely the installation position regarding the up-down direction of a shoji side support by making a pair of attachment hole formed in the attachment seat part 62 into a long hole. Similarly, although the illustration is omitted, the shoji side support 39 can be covered with a resin cover.

In the case of the window device 1a of the present example having the above-described configuration, the operation of switching the self-propelling prevention device 37 between the unlocked state and the locked state is performed as follows.
First, the operation for switching from the unlocked state to the locked state will be described.
First, the outer shoji 17 is moved from the closed position as shown in FIG. 2 in the opening direction, and the screen door 19 is moved to the closed position. When the screen door 19 is originally present at the closed position, such a moving operation of the screen door 19 is not necessary, and it is sufficient to slightly open the outer shoji 17 from the closed position.

  Next, the rotary locking piece 41 constituting the screen door side locking device 38 is operated by fingers through the opening (gap) between the vertical frame 22a of the window frame 16 and the door rod 26a of the outer shoji 17. Then, the rotation locking piece 41 is rotated from the unlock position arranged in the vertical direction in the case portion 40 toward the indoor side (front side) and downward with the pivot shaft 54 as the rotation center. Thereby, the protrusion amount from the indoor side wall 58 of the front half 51 constituting the rotating locking piece 41 is increased, and finally the base half 50 of the rotating locking piece 41 is notched 48. Engage with the bottom of the groove. Thereby, this rotation locking piece 41 is moved to a lock position.

  Then, the said shoji 17 is moved to a closed position so that this shoji 17 and the said screen door 19 may overlap an indoor / outdoor direction. In other words, the door toe 26a that constitutes the shoji 17 and the vertical frame 22a that constitutes the window frame 16 are abutted.

  As a result, the receiving piece 63 of the shoji side receiving tool 39 fixed to the door rod 26a of the outer shoji 17 is placed on the front half 51 of the rotary locking piece 41 with respect to the outer shoji 17. The locked state is realized by engaging the window frame 16 in the width direction from the rear side (the right side in FIGS. 5 and 6) in the closing direction. More specifically, the width direction one end edge of the receiving piece 63 (the receiving piece main body portion 65 and the guide portions 66a and 66b) facing the width direction of the window frame 16 and the first half of the rotating locking piece 41 are arranged. The inner side surface of the receiving piece main body portion 65 and the outdoor side of the locking plate portion 52 are engaged with the side surface in the width direction of the portion 51 (portion other than the locking plate portion 52) and opposed to the indoor / outdoor direction. Engage the sides. As a result, in this example, it is possible to prevent the screen door 19 from traveling in the horizontal direction (moving from the closed position to the opening direction) even in a strong wind, and the screen door 19 falls off toward the outdoor side. It can also be effectively prevented. Although illustration is omitted, when the screen door 19 is dropped due to a strong wind, the vertical middle portion of the screen door 19 moves (curves) toward the outdoor side, so the locking plate portion 52 is also on the outdoor side {FIG. 14 to the left of (B)}. Therefore, the screen door 19 can be more firmly engaged by engaging the upper and lower end portions of the locking plate portion 52 with the guide portions 66a and 66b in the vertical direction.

On the other hand, in order to switch the self-running prevention device 37 from the locked state as described above to the unlocked state, the following operation is performed.
First, the external shoji 17 is moved in the opening direction from the closed position.
In the case of this example, when the outer shingles 17 are moved from the closed position to the opening direction, the receiving piece 63 is not rotated from the locked position, but the receiving piece 63 is moved to the rotating locked piece 41. Therefore, the engagement between the receiving piece 63 and the rotating locking piece 41 is substantially released and the unlocked state is obtained. However, in this state, the screen door 19 is not allowed to move freely in the opening direction, and moves in the opening direction according to the amount of movement (opening range) from the closed position of the shoji 17. It only becomes possible to do. For this reason, it is not a complete unlocked state but an incomplete unlocked state (half-locked state). Therefore, in order to realize a completely unlocked state in which the screen door 19 can be moved regardless of whether or not the external shoji 17 is moved to the open position, the following operations are also performed. There is a need.

  In other words, the rotary locking piece 41 constituting the screen door side locking device 38 is operated by fingers through the opening of the vertical frame 22a of the window frame 16 and the door rod 26a of the external shoji 17. And this rotation locking piece 41 is rotated from the lock position arrange | positioned in the horizontal direction toward the outdoor side and the upper direction centering | focusing on the said pivot 54. As shown in FIG. Thereby, the rotation locking piece 41 is moved to the unlock position. And the protrusion amount from the said indoor side wall 58 of the front half part 51 of the said rotation locking piece 41 is made into zero.

  As a result, the receiving piece 63 of the shoji side receiving tool 39 and the front half 51 of the rotating locking piece 41 are disengaged with respect to the width direction of the window frame 16, and indoor and outdoor. The direction is also disengaged to achieve a completely unlocked state. As a result, it is possible to freely move the screen door 19 in the opening / closing direction without moving the outer screen 17 from the closed position.

According to the window device 1a of the present example having the above-described configuration, workability for preventing the screen door 19 from self-propelling can be improved, and the lock can be hardly forgotten.
That is, in the case of this example, as described above, it is only necessary to open the screen 17 (especially, when the screen door 19 is in the closed position), the circuit door side locking device 38 is configured. The movable locking piece 41 can be easily rotated from the room. In addition, if the rotation locking piece 41 is moved to the lock position where the engagement with the receiving piece 63 can be performed by such a rotation operation, the armature 17 is only moved to the closed position. Thus, the locking state can be realized by engaging the receiving piece 63 and the rotating locking piece 41 in the width direction of the window frame 16.

  In the case of this example, even if the rotary locking piece 41 is moved to the locked position, the screen door can be moved within the open range of the screen by moving the screen 17 in the opening direction. 19 can be moved in the opening direction (a half-locked state can be realized). For this reason, for example, even when the screen door 19 needs to be opened for cleaning work, the rotational locking piece 41 is not moved to the unlock position where the engagement with the receiving piece 63 is disabled. However, the screen door 19 can be opened to some extent. Then, after the cleaning work is completed, even if the special operation for preventing the screen door 19 from self-propelling is not performed, the outer screen 17 can be moved to the closed position together with the screen door 19 to obtain a complete locked state. realizable.

  As described above, according to the window device 1a of the present example, all the operations required to prevent the screen door 19 from self-propelling (the operation of the screen door side locking device 38 and the opening / closing operation of the screen door 17) are all performed indoors. Things are possible. Further, even when the screen door 19 needs to be temporarily opened, it can be performed without moving the rotating locking piece 41 from the lock position, and the operation of the rotating locking piece 41 can be made unnecessary. . Accordingly, in the case of this example, the workability for preventing the screen door 19 from self-propelling can be improved, and the lock can be hardly forgotten.

  Further, in the case of this example, the screen door side locking device 38 and the shoji side side receiving device 39 constituting the self-propelled prevention device 37 are removed from the window frame 16 instead of the window frame 16 fixed to the building. Since it is attached to the above-described shoji 17 (door-end fence 26a) and the screen door 19 (vertical fence 32a), this attachment work can be performed at a place away from the living room. Therefore, it is possible to reduce the burden on the resident during construction.
