Description

  The present invention relates to a joinery for mounting a shoji screen on an opening frame in a so-called kendo type.

  Some joinery made of shojis such as an opening frame and a screen door are equipped with a shoji with a so-called kendo on the opening frame. For example, in the open frame, insertion grooves are formed in the upper and lower frames facing each other in the opening frame, and the upper edge of the shoji is inserted into the insertion groove of the upper frame first, and then the shoji The lower armpit is dropped into the insertion slot of the lower frame. In addition, in fittings in which fin-shaped rails are provided on the upper frame and the lower frame that face each other in the opening frame, insertion grooves are formed on the upper and lower folds of the shoji, respectively. The upper frame rail is first inserted into the insertion groove, and then the lower frame rail is inserted into the insertion groove of the lower rod.

  In this type of joinery, when the shoji moves upward with respect to the opening frame, the lower eyelid may deviate from the lower frame, and the shoji may fall out of the opening frame. For this reason, as for the conventional joinery, what is provided with the means for preventing the situation where a shoji falls carelessly from an opening frame is already provided.

  For example, in Patent Document 1, a slip-off preventing unit is slidably disposed in such a manner as to advance and retreat from the outer edge surface of the upper collar, and the slip-preventing unit is always directed upward between the slip-preventing unit and the upper collar. A leaf spring to be pressed is interposed. In such a joinery, the slip-off preventing unit can be pushed into the upper arm against the elastic force of the leaf spring, so that the work for supporting the shoji with the opening frame in a quick manner does not become complicated. Moreover, after the shoji is supported with respect to the opening frame, the detachment prevention unit moves forward from the outer edge surface of the upper collar by the elastic force of the leaf spring, so the distance that the shoji can move above the opening frame is limited. Will be. Therefore, even if an external force is applied to the shoji to move it upward, it is possible to prevent the shoji from being accidentally dropped from the opening frame.

JP 2001-31371 A

  By the way, in order to surely prevent the shoji from falling off the opening frame in the joinery described above, a leaf spring having a spring constant as large as possible is applied so that the comet prevention unit is not easily pushed in by an external force applied to the shoji. It is preferable to make it. However, when a leaf spring having a large spring constant is applied, naturally, a large operating force is required to support the shoji on the opening frame, which may significantly impair the workability.

  In view of the above circumstances, the present invention provides a fitting that can more reliably prevent inadvertent dropping of the shoji from the opening frame without hindering the operation of supporting the shoji to the opening frame. With the goal.

  In order to achieve the above object, a joinery according to the present invention includes an opening frame and a shoji framed by four rounds, and the above-described opening frame is attached to the opening frame by attaching the shoji to the opening frame in a jerky manner. In the fitting that supports the shoji, the base member attached to the surface located on the indoor side or the outdoor side in the prospective direction of the saddle, and the shaft centered along the longitudinal direction of the saddle to which the base member is attached. An anti-slip member that is disposed on the base member in a movable manner and rotates between a protruding state protruding from an outer edge surface serving as an outer periphery of the shoji and a non-projecting state retracted from the outer edge surface; And a retaining unit for maintaining the retaining member in the projecting state when the retaining member is disposed in the projecting state with respect to the base member. .

  In the joinery according to the present invention, in the joinery described above, the maintaining means is formed at portions corresponding to each other of the base member and the slip-off preventing member, and the slip-off preventing member protrudes from the base member. A pair of hook-shaped members for restricting rotation of the locking member in a direction of shifting to the non-projecting state with respect to the base member by engaging the hook-shaped portions with each other when arranged in a state; It is characterized by that.

  In the joinery according to the present invention, in the joinery described above, when the stopper member is arranged in the non-projecting state, the inner edge surface of the heel to which the base member is attached is directed inward in the in-plane direction of the shoji. It is characterized by protruding.

  Further, in the joinery according to the present invention, in the joinery described above, a spring member that constantly urges the slip-off preventing member in the non-projecting direction is interposed between the base member and the slip-off preventing member. It is characterized by that.

  In the joinery according to the present invention, in the joinery described above, the base member is attached to the heel by fastening a screw through a screw insertion hole formed in the base member, and the comet prevention member Has a cover portion that covers the head of the screw when arranged in the protruding state.

  In the joinery according to the present invention, in the joinery described above, the anti-slip member has a facing portion that faces the outer edge surface of the ridge when arranged in the protruding state. .

  According to the present invention, after the shoji is supported by the opening frame, when the slip-off preventing member is rotated and arranged in the protruding state with respect to the base member, the slip-off preventing member faces outward from the outer edge surface of the bag. Since it protrudes, the movement of the shoji with respect to the opening frame is restricted, and the falling off from the opening frame is prevented. In addition, since the locking member rotates about the axis along the longitudinal direction of the collar with respect to the base member, the locking member that is in the protruding state even when a large force is applied to the shoji is in a non-projecting state. There is no fear of shifting, and it is possible to reliably prevent inadvertent dropping of the shoji from the opening frame. Furthermore, since the slip-off preventing member is disposed at a position retracted from the outer edge surface of the bag when in the non-projecting state, there is no possibility that the operation for supporting the shoji with respect to the opening frame becomes complicated.

  Hereinafter, preferred embodiments of a joinery according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows a joinery that is an embodiment of the present invention. The joinery illustrated here is configured by supporting the fixed screen 20 and the movable screen 30 on the opening frame 10 and further supporting the fixed screen door (screen screen) 40 on the outdoor side of the movable screen 30.

  The opening frame 10 has a rectangular frame shape in which the ends of the upper and lower upper frames 11 and 12 are connected by vertical frames 13 and 13 respectively. The opening frame 10 corresponds to the opening WO formed in the wall W of the house. It is arranged along the edge. The upper frame 11, the lower frame 12, and the pair of vertical frames 13 and 13 are each provided with a partition wall portion 14 on the prospective surface. The partition wall portion 14 is located in the plane of the opening frame 10 from the portion that is substantially in the center in the prospective direction on the lower surface of the upper frame 11, the upper surface of the lower frame 12, and the inner surfaces of the pair of vertical frames 13 and 13 that face each other It is a thin plate-like portion protruding toward the inside in the direction.

  Although not shown in the drawing, the fixed shoddle 20 and the movable shoddle 30 are face materials each holding a glass plate inside a saddle constructed by assembling four saddles. The fixed shoddle 20 and the movable shoddle 30 have a vertical dimension that is almost ½ of the opening frame 10 and a prospective dimension that is smaller than ½ of the upper frames 11, 12, and 13 that constitute the opening frame 10. It is comprised so that it may become.

  The fixed shoji 20 is disposed in a portion located on the outdoor side of the above-described partition wall portion 14 in the upper half portion of the opening frame 10. More specifically, the fixed shoji 20 is in a state of being fixed to the opening frame 10 by attaching the upper collar 21 to the upper frame 11 of the opening frame 10. The lower arm 22 of the fixed shoji 20 also functions as an upper frame of a lower opening frame (opening frame) 10 ′ constituted by the lower frame 12 of the opening frame 10 and the lower half of the pair of vertical frames 13 and 13. The engagement fins 22a are provided on the lower surface that is the prospective surface. The engagement fins 22 a are thin plate-like portions projecting from the lower surface of the lower collar 22 toward the inner side in the in-plane direction of the lower opening frame 10 ′, and extend along the longitudinal direction of the lower collar 22.

  The movable shoji 30 is disposed in a portion of the opening frame 10 that is closer to the indoor side than the partition wall portion 14, and is supported in such a manner that it can move in the vertical direction with respect to the opening frame 10. When the movable shoji 30 is disposed at the lowermost position with respect to the opening frame 10, the movable shoji 30 has a size for closing the entire opening of the opening frame 10 together with the fixed shoji 20. On the other hand, when the movable shoji 30 is moved upward, the opening frame 10 can be opened according to the amount of movement. Moreover, the movable shoji 30 can function as an inward-turning window when it is arranged at a position slightly raised from the bottom relative to the opening frame 10, as shown by a two-dot chain line on the right side in FIG. is there. That is, when the movable shoji 30 is operated to release the locking means (not shown) provided between the movable shoji 30 and the vertical frames 13 and 13 of the opening frame 10 from this state, the movable shoji 30 and the vertical frames 13 and 13 The engaged state is released, and the upper end portion of the lower collar 32 can be opened to the indoor side with the lower rod 32 as an axis.

  On the other hand, as shown in FIG. 2, the fixed screen door 40 is a surface material in which a mesh 44 is stretched inside a cage constructed by assembling an upper cage 41, a lower cage 42, and a pair of left and right vertical rods 43, 43. Yes, the opening frame 10 has a width that can be fitted between the pair of vertical frames 13 and 13. As shown in FIG. 1, the dimension of the fixed screen 40 along the vertical direction is smaller than the distance between the upper surface of the lower frame 12 in the opening frame 10 and the lower surface of the lower rod 22 in the fixed screen 20, and the fixed screen 20 is configured to be larger than the distance between the lower end of the engagement fin 22a projecting from the lower collar 22 and the upper surface of the engagement base member 12a provided on the upper surface of the lower frame 12 in the opening frame 10. .

  The side surface of the engagement base member 12a located on the indoor side in the prospective direction is the same position in the prospective direction as the side surface located on the indoor side in the prospective direction in the engagement fins 22a provided on the lower collar 22 of the fixed shoji 20. It is attached to the part, and constitutes an insertion groove 10 a that opens upward (inward in the in-plane direction of the opening frame 10) between the lower wall 12 and the partition wall portion 14. The protrusion height of the engagement base member 12a from the lower frame 12 is along the vertical direction of the fixed screen 40 from the distance between the upper surface of the lower frame 12 in the opening frame 10 and the lower surface of the lower collar 22 in the fixed shoji 20. It is set to be smaller than the value obtained by subtracting the dimension.

  As shown in FIGS. 1 and 2, the fixed screen door 40 is provided with a gripping member 45 on each of a pair of vertical rods 43, 43, and an inner surface 41 a located on the indoor side in the prospective direction on the upper rod 41. Is provided with a detachment prevention unit 50.

  The gripping member 45 is a part that becomes a handle when the fixed screen door 40 is handled. In the present embodiment, a gripping member 45 configured in a rectangular frame shape is fixed to the prospective surfaces of the vertical rods 43 and 43.

  As shown in FIGS. 3 to 8, the locking unit 50 includes a base member 150 and a locking member 250. The base member 150 is formed by integrally forming a substrate portion 151, a pair of bearing portions 152, and a pair of pressing operation portions 153 using a synthetic resin material. As shown in FIGS. 3 and 7, the substrate portion 151 has a horizontally long rectangular flat plate shape, has a screw insertion hole 151 a at the center thereof, and has a long side opposite to the bearing portion 152. One end is bent at a substantially right angle. In the following, for convenience, the long side bent in the substrate part 151 is referred to as the upper side 151A, the other long side on the bearing part 152 side is referred to as the lower side 151B, and the remaining two sides are referred to as the short side 151C. The surface located on the indoor side is called inner surface 151D, and the surface located on the outdoor side in the prospective direction is called outer surface 151E.

  Each of the pair of bearing portions 152 has a columnar shape, and is provided in a state where the axial centers along the longitudinal direction of the upper collar 41 are matched with each other at the end surface of the lower side 151B in the substrate portion 151. As is apparent from the drawing, the pair of bearing portions 152 ensure a gap between each other, and each end portion protrudes from the short side 151C of the substrate portion 151 to the outside in the longitudinal direction of the upper collar 41. Is provided on the substrate 151. Although not clearly shown in the drawing, each bearing portion 152 is formed with a bearing groove for receiving a shaft member from an opening located on the outer surface 151E side of the substrate portion 151 and rotatably supporting the shaft member. It is.

  The pair of pressing operation portions 153 are radially outward from the peripheral surface of the bearing portion 152 that protrudes outward in the longitudinal direction of the upper collar 41 from the short side 151C of the substrate portion 151 in a manner facing the short side 151C of the substrate portion 151. It is a part protruding in the direction. The respective pressing operation portions 153 are curved so that the portions that are outward in the longitudinal direction of the upper collar 41 are convex outward, and when the convex portions are pressed, the bearing portion 152 It is possible to elastically deform in the direction approaching the short side 151C of the substrate part 151 with the connecting part as a fulcrum. These pressing operation portions 153 are provided with base-side hook-shaped members 154 at portions that are inward of each other.

  The base side flange-shaped member 154 extends from the pressing operation portion 153 toward the inside in the longitudinal direction of the upper flange 41, and then bends at a substantially right angle in a direction away from the bearing portion 152. A base side flange 154A is provided at the end. As shown in FIGS. 3, 4, and 8, the base-side hook-shaped portion 154A includes a base-side inclined surface 154A1 and a base-side engaging surface 154A2, and projects in a direction away from each other. Yes. The base-side inclined surface 154A1 is a plane that is gradually inclined in a direction away from the short side 151C of the substrate portion 151 as it goes from the indoor side in the prospective direction toward the outdoor side. Each of the base-side inclined surfaces 154A1 has a function of elastically deforming the pressing operation portion 153 toward the direction close to the short side 151C of the substrate portion 151 when a pressing force is applied. The base side engagement surface 154A2 is a plane extending from the end located on the base side inclined surface 154A1 toward the short side 151C of the base plate part 151 from the end portion located outside the prospective direction. It is formed to be parallel to the inner surface 41a located on the indoor side.

  As shown in FIG. 3, the base member 150 having the above configuration has the outer surface 151 </ b> E of the substrate unit 151 in the state where the upper side 151 </ b> A of the substrate unit 151 is brought close to the outer edge surface 41 b which is the upper surface of the upper plate 41. 41, it is brought into contact with the inner surface 41a located on the indoor side in the prospective direction, and the mounting screw 160 is fastened to the upper rod 41 through the screw insertion hole 151a from this state, whereby the inner surface 41a of the upper rod 41 is fixed. It is attached. As is apparent from the drawing, in this state, the base member 150 has a size that allows the base plate portion 151, the pair of bearing portions 152, and the pair of pressing operation portions 153 to fit on the inner surface 41 a of the upper collar 41 (the upper collar 41 The size of the upper collar 41 is not protruded from either the outer edge surface 41b that is the upper surface of the upper collar 41 or the inner edge surface 41c that is the lower surface.

  On the other hand, as shown in FIGS. 2 to 8, the locking member 250 of the locking unit 50 is formed by integrally forming a cover portion 251, a shaft portion 252, and a regulating portion (opposing portion) 253 with a synthetic resin material. . The cover portion 251 is a horizontally long flat plate-like member having a size sufficient to cover the base side flange-like member 154 provided in the base plate portion 150 and the pressing operation portion 153 in the base member 150. The shaft portion 252 has a columnar shape and has shaft members 252a having small diameters on both end faces thereof, and the shaft center of the shaft member 252a is parallel to the long side of the cover portion 251 (the length of the upper collar 41). In the same direction as the direction), the cover portion 251 is disposed substantially at the center of one long side. The shaft portion 252 is configured such that the length along the axial direction can be disposed between the pair of bearing portions 152 in the base member 150 described above. The restricting portion 253 is a portion that bends and extends in a substantially right angle direction from the portion that is the other long side of the cover portion 251. In the restricting portion 253, the distance from the shaft member 252a of the shaft portion 252 to the extended end portion farthest from the shaft member 252a is sufficiently greater than the distance from the shaft center of the bearing portion 152 to the upper side 151A of the base plate portion 151 in the base member 150 described above. It is large.

  As shown in FIGS. 3 and 5 to 7, the locking member 250 having the above-described configuration has the shaft portion 252 disposed between the bearing portions 152 of the base member 150 and extends from both end surfaces of the shaft portion 252. The existing shaft members 252a are respectively accommodated in bearing grooves (not shown) of the base member 150, so that the shaft members 252a are connected to the base member 150 in such a manner that the shaft members 252a can rotate around the axis of the shaft member 252a. When the locking member 250 is rotated about the axis of the shaft member 252a with respect to the base member 150, the bent tip portion of the restricting portion 253 and the bent tip portion of the base plate portion 151 of the base member 150 protrude close to each other. It becomes a state.

  As is clear from FIG. 6, the restricting portion 253 of the stopper member 250 is configured such that the protruding length from the cover portion 251 is larger than the plate thickness direction dimension (dimension along the prospective direction) of the base member 150. Yes, when the cover portion 251 covers the substrate portion 151 of the base member 150 and enters the above-described protruding state, the tip portion thereof exceeds the outer surface 151E of the substrate portion 151 and is close to the outer edge surface 41b of the upper collar 41. It is possible to face each other.

  A spring member 350 is interposed between the detachment preventing member 250 and the base member 150, and the cover-side hook-like member 254 is disposed at a portion corresponding to the base-side hook-like member 154 of the base member 150 in the cover portion 251. Is provided. As shown in FIGS. 5 and 6, the spring member 350 is a torsion coil spring provided so as to be wound around the shaft member 252a, and the anti-separation member 250 with respect to the base member 150 is in a non-projecting state described later. It is always energized in the direction (FIGS. 3 and 5).

  As shown in FIGS. 3 and 4, the cover-side hook-like member 254 is provided so as to protrude from the surface covering the base member 150 in the cover portion 251 of the locking member 250 toward the same direction as the restricting portion 253. The projecting end portion has a cover side flange portion 254A. As shown in FIGS. 3, 4, and 8, the cover-side hook-like portion 254A includes a cover-side inclined surface 254A1 and a cover-side engagement surface 254A2, and protrudes in directions close to each other. Yes. The cover-side inclined surface 254A1 is a flat surface that is inclined in a direction in which the distance from each other gradually increases as the distance from the cover portion 251 increases. These cover-side inclined surfaces 254A1 change from the non-projecting state (FIGS. 3 and 5) to the projecting state (FIG. 6) when the external force is not applied to the pressing operation portion 153 of the base member 150. When rotated in the direction, each is provided at a position where it abuts against the base-side inclined surface 154A1 of the base-side saddle-shaped member 154. The cover-side engagement surface 254A2 is a flat surface that extends in a manner parallel to the base-side engagement surface 154A2 of the base member 150 in the protruding state.

  In the locking unit 50 configured as described above, as shown in FIGS. 3 and 5, when the locking member 250 is in a non-projecting state not covering the base member 150, On the other hand, there is no structure which protrudes from the outer edge surface 41b. That is, there is no configuration that protrudes outward in the in-plane direction from the outer edge surface 41 b that is the outer periphery of the fixed screen 40, and there is no change in the dimension along the vertical direction of the fixed screen 40.

  Therefore, as shown on the left side in FIG. 1 from this state, the upper arm 41 of the fixed screen door 40 is inserted into a portion that is on the indoor side of the engagement fin 22a provided on the lower arm 22 of the stationary shoji 20, Thereafter, if the lower arm 42 of the fixed screen door 40 is pushed into the room side, the engagement base member 12a can be easily climbed without requiring any great operating force. Thereby, the lower fin 42 of the fixed screen 40 is dropped into the insertion groove 10 a formed in the lower frame 12 of the opening frame 10, so that the engagement fin 22 a, the engagement base member 12 a, and the partition wall portion 14 of the lower frame 12 The fixed screen 40 is supported by the lower opening frame 10 '.

  From this state, for example, if the movable shoji 30 functions as an inward window, and the upper end portion is tilted and opened to the indoor side with the lower eyelid 32 as an axis as shown on the right side in FIG. The unit 50 can be operated, and the detachment preventing member 250 and the base member 150 can be operated in a protruding state facing each other.

  That is, as shown in the arrow R in the figure, the anti-separation members 250 are rotated with respect to the base member 150 in a direction opposite to each other and are pressed against the base member 150 as they are. The pressing operation portion 153 of the base member 150 is elastically deformed in a direction approaching each other by the tilting action of the base side inclined surface 154A1 of the base side flange portion 154A and the cover side inclined surface 254A1 of the cover side flange portion 254A. Thereafter, when the sliding contact state between the base side inclined surface 154A1 and the cover side inclined surface 254A1 is finished and the cover side engaging surface 254A2 enters beyond the base side engaging surface 154A2, the pressing operation portion 153 of the base member 150 is operated. Is restored to its original state by its own elastic restoring force. As a result, as shown in the left half of FIG. 7 and the left half of FIG. 8, the cover side engagement surface 254A2 protrudes opposite to the base side engagement surface 154A2. It becomes a state.

  When the locking member 250 is in the protruding state, when the locking member 250 is rotated in a direction to move away from the base member 150 without operating the pressing operation portion 153, the locking member 250 extends in a direction substantially perpendicular to the direction. Since the existing cover-side engagement surface 254A2 and base-side engagement surface 154A2 are in contact with each other, the rotation of the anti-separation member 250 with respect to the base member 150 is prevented.

  In this protruding state, as shown on the right side in FIG. 1, the restricting portion 253 protrudes upward from the upper arm 41 of the fixed screen 40, and substantially the lower screen 22 of the fixed screen 40 and the fixed shoji 20. The distance to the lower surface is shortened, and the movable distance of the fixed screen door 40 upward relative to the lower opening frame 10 'is limited.

  Therefore, even if an external force is applied to the fixed screen 40 to move it upward, it is possible to prevent the fixed screen 40 from being inadvertently dropped from the lower opening frame 10 '. Moreover, since the anti-separation member 250 rotates about the axis along the longitudinal direction of the upper collar 41 with respect to the base member 150, a part of the restricting portion 253 faces the outer edge surface 41b of the upper collar 41. Therefore, even when a large force is applied to the fixed screen door 40, the blocking member 250 in the closed state is not rotated in the direction away from the base member 150, and the restricting portion 253 continues. It will be maintained in the state which protruded from the outer edge surface 41b of the upper collar 41, and it will become possible to prevent the fixed screen door 40 from dropping carelessly from the lower opening frame 10 '. Furthermore, the head of the mounting screw 160 for holding the base member 150 on the upper collar 41 is covered with the anti-separation member 250, and the appearance quality as a joinery is not impaired.

  On the other hand, when the fixed screen door 40 is removed from the lower opening frame 10 ′, as shown in the right half of FIG. 7 and the right half of FIG. 8, the pressing operation portions 153 provided on the base member 150 in the detachment prevention unit 50 are mutually connected. When pressed toward the inner side (the approaching direction), the cover-side engagement surface 254A2 moves inward along the longitudinal direction of the upper collar 41 with respect to the base-side engagement surface 154A2, and from the state of facing each other It will deviate. Therefore, if the anti-separation member 250 is operated to rotate away from the base member 150 from this state, it can be easily released, and the restricting portion 253 is retracted from the outer edge surface 41b of the upper rod 41, that is, the fixed screen door. The outer peripheral surface 41b, which is the outer periphery of 40, can be arranged at a position that does not protrude outward in the in-plane direction (non-projecting state).

  Therefore, if the fixed screen door 40 is moved upward from the non-projecting state, the lower surface of the lower rod 42 is disposed above the upper surface of the engagement base member 12a, and the lower rod 42 is moved to the near side as it is. If it is pulled out, the fixed screen door 40 can be removed from the lower opening frame 10 '.

  In the above-described embodiment, the joinery constituted by fixing the fixed screen door 40 to the lower opening frame 10 'is exemplified. However, the shoji is not necessarily a screen door and is movable. The same applies to shoji screens (sliding windows, single sliding windows, etc.). For example, in the case of a sliding window or a sliding window that slides in the left-right direction, the upward movement of the shoji with respect to the opening frame is restricted by the slip-off preventing unit. Further, the shoji type is supported by the opening frame in the vertical direction along the vertical direction, but the present invention can also be applied to a type in which the shoji is supported by the opening frame in the vertical direction along the left and right direction. In the case of the quick-running type along the left-right direction, the detachment prevention unit may be attached to at least one of the hooks to be inserted, that is, the vertical hooks.

  Further, in the above-described embodiment, when the slip prevention member 250 is rotated in a direction away from the base member 150, the slip prevention member 250 from the upper collar 41 of the fixed screen door 40 as shown by a two-dot chain line in FIG. Protrudes to the screen 44 side (inside the upper ridge 41 in the in-plane direction of the screen door 40), and the appearance is unnatural, so that the fixed screen door 40 does not function to prevent the lock screen 40 from coming off. It can be confirmed visually. Therefore, there is no fear of forgetting to put on the detachment prevention unit 50. However, the configuration of the come-off prevention member 250 is not limited to this, and it is not always necessary to protrude to the inner side in the in-plane direction of the shoji from the kite in the opened state. Further, since the spring member 350 that urges the base member 150 in the direction to always open the slip-off preventing member 250 is interposed, the spring member when the pressing operation portions 153 are pressed inward from each other. The detachment preventing member 250 can be reliably arranged in the non-projecting state by the urging force of 350. Thereby, the detachment preventing member 250 does not stop at a halfway rotation position with respect to the base member 150, and the user can visually confirm the protruding state and the non-projecting state. However, the configuration of the locking unit 50 is not limited to this, and the spring member 350 is not necessarily provided.

  Furthermore, in the above-described embodiment, when the locking member 250 is disposed in a protruding state with respect to the base member 150, a part of the locking member 250 (the restricting portion 253) is opposed to the outer edge surface 41b of the flange 41. Therefore, the resistance against external force is increased, but is not necessarily limited thereto.

  In the above-described embodiment, the hook member is provided on each of the base member and the locking member, and these are engaged with each other so that the locking member is maintained in a protruding state with respect to the base member. However, the maintaining means is not necessarily limited to that engaging the hook-shaped portion. For example, a pin and a hole are formed between the base member and the locking member, and when the locking member is opposed to the base member, the locking member is maintained in a protruding state by press-fitting the pin into the hole. It is also possible.

  Furthermore, in the above-described embodiment, the base member 150 of the locking unit 50 is attached to the inner surface 41a located on the indoor side in the prospective direction on the upper arm 41 (the shoji screen) of the fixed screen door 40. In 41, you may attach to the surface located in the outdoor side of a prospective direction. In this case, the detachment prevention unit 50 is positioned on the outer side of the prospective direction on the upper collar 41, and the detachment prevention unit 50 is operated from the outdoor side.
