Description

This disclosure relates to a screen door attachment and a screen door.

Conventionally, frameless screen doors are known in which the edges of the screen are fixed to the frame by means of a resin attachment (see, for example, Patent Document 1). In this screen door, the attachment placed on the edge of the screen is fitted into a fitting groove provided in the frame of the fixture, thereby attaching the screen to the frame.

JP 2010-281098 A

The attachment that is fitted into the fitting groove is removed by inserting a removal tool such as a flat-head screwdriver into the gap between the attachment and the fitting groove and lifting the attachment out of the fitting groove. However, because the surface of the attachment is flat, there is a problem that it is difficult for users who are replacing a screen door for the first time to understand how to remove the attachment. In addition, it is necessary to prepare a removal tool such as a flat-head screwdriver when replacing the screen door.

Therefore, the inventors have come up with a problem of how to make it possible to easily remove a screen attachment that fits into a fitting groove in a frame body from the fitting groove without the need for a jig.

The attachment for a screen door disclosed herein comprises an attachment body that is placed on the edge of the screen of the screen door and removably engages with a fitting groove provided on the frame body to fix the edge to the frame body, and a removal member that is a hard part that protrudes from the surface of the attachment body.

(Overall composition of fittings)
1, 2 and 3 show a screen door-equipped fitting 1 (hereinafter simply referred to as "fitting 1") equipped with a screen door of this embodiment. The fitting 1 comprises a frame 2 attached to an opening (not shown) formed in a building framework, a shoji screen 3 that is housed in the frame 2 so as to be able to open and close, and a screen door 4 that is stretched on the indoor side of the shoji screen 3. X1 shown in the figures indicates the outdoor side of the fitting 1, and X2 indicates the indoor side of the fitting 1.

The fitting 1 is a composite fitting having a frame 2 made of metal such as aluminum and resin such as polyvinyl chloride, and has excellent heat insulation properties. That is, the frame 2 is formed into a rectangular frame by an upper horizontal frame 21, a lower horizontal frame 22, and left and right vertical frames 23, 24. As shown in Figures 2 and 3, the upper horizontal frame 21, the lower horizontal frame 22, and the vertical frames 23, 24 are respectively composed of a metal upper horizontal frame 211, a metal lower horizontal frame 221, and a metal vertical frame 231, 241 to which the shoji screen 3 is attached so that it can be opened and closed, and a resin upper horizontal frame 212, a resin lower horizontal frame 222, and a resin vertical frame 232, 242 to which the screen door 4 is stretched. The resin upper horizontal frame 212 and the resin lower horizontal frame 222 are attached to the inside and indoor side of the metal upper horizontal frame 211 and the metal lower horizontal frame 221, respectively, and the resin vertical frames 232, 242 are attached to the inside and indoor side of the metal vertical frames 231, 241, respectively.

The shoji screen 3 is arranged inside the metal upper horizontal frame 211, the metal lower horizontal frame 221, and the metal vertical frames 231, 241, and on the exterior side of the resin upper horizontal frame 212, the resin lower horizontal frame 222, and the resin vertical frames 232, 242. The shoji screen 3 is constructed by fitting two pieces of glass 35, 35 with a spacer 36 between them inside the upper frame 31, the lower frame 32, and the vertical frames 33, 34, which are assembled into a rectangular frame. The shoji screen 3 in this embodiment is a vertical sliding window that is attached to the frame body 2 so as to be rotatable around a rotation axis (not shown) provided at one end of the upper frame 31 and the lower frame 32. The shoji screen 3 is opened by rotating around the rotation axis toward the exterior side, and stored by rotating toward the interior side.

(Configuration of the screen door)
The screen door 4 is disposed on the interior side of the shoji screen 3, and is stretched across the upper resin horizontal frame 212, the lower resin horizontal frame 222, and the resin vertical frames 232, 242 of the frame body 2. More specifically, the visible surfaces 232a, 242a of the left and right resin vertical frames 232, 242 are each provided with an engagement groove 25 extending in the up-down direction. The visible surfaces 212a, 222a of the upper resin horizontal frame 212 and the lower resin horizontal frame 222 are each provided with an engagement groove 26 extending in the left-right direction. The edges of the screen door 4 are detachably attached to the engagement grooves 25, 26 via attachments described below. The engagement grooves 25, 26 are continuous around the four periphery of the frame body 2.

The screen door 4 is shown in Figure 7. The top, bottom, left and right of the screen door 4 shown in Figure 7 correspond to the top, bottom, left and right of the fitting 1 shown in Figure 1. The screen door 4 comprises a rectangular screen portion 41, a pair of vertical attachments 42, 42 arranged on the left and right edges of the screen portion 41, and a pair of horizontal attachments 43, 43 arranged on the top and bottom edges of the screen portion 41. The vertical attachments 42 fit into the fitting grooves 25 of the resin vertical frames 232, 242, respectively. The horizontal attachments 43 fit into the fitting grooves 26 of the resin upper horizontal frame 212 and the resin lower horizontal frame 222, respectively.

The mesh section 41 is formed by sewing or gluing a tape section 412 having numerous teeth 412a to the four peripheral edges of the mesh section main body 411, with the teeth 412a facing outward. The teeth 412a of the tape section 412 on the vertical side of the mesh section 41 are formed over the entire vertical length of the mesh section 41. The teeth 412a of the tape section 412 on the horizontal side of the mesh section 41 do not extend over the entire horizontal length of the mesh section 41, and a predetermined gap is provided between the teeth 412a of the vertical tape section 412 to allow the vertical tape section 412 to be inserted into the vertical attachment 42, as described below.

When the screen door 4 is not attached to the frame 2 of the fitting 1, the vertical attachment 42 is attached by engaging with the tape portion 412 on the vertical side of the mesh portion 41. However, the horizontal attachment 43 is not engaged with the mesh portion 41 and is separate from the mesh portion 41. Because the horizontal attachment 43 is separate from the mesh portion 41, the mesh portion 41 can be easily rolled up around one of the vertical attachments 42 before being attached to the frame 2 and after being removed from the frame 2, thereby reducing packaging. This allows space to be saved when storing and transporting the mesh portion 41. The detailed configurations of the vertical attachment 42 and the horizontal attachment 43 will be described later.

(Configuration of fitting groove)
The configuration of the fitting groove 25 will be described with reference to Fig. 4 and Fig. 8. Fig. 4 shows a state in which the vertical attachment 42 is attached to the fitting groove 25 of the vertical resin frame 232. Fig. 8 shows a state in which the vertical attachment 42 is attached to the fitting groove 25 of the vertical resin frame 232.

The fitting groove 25 is a recessed groove capable of accommodating the vertical attachment 42. The inner surfaces 251a, 251b located on the indoor and outdoor sides of the fitting groove 25 have ridges 252a, 252b extending along the length direction that protrude toward each other, narrowing the entrance of the fitting groove 25. The tip surfaces 253a, 253b of the ridges 252a, 252b are tapered and widen toward the outside of the fitting groove 25. The ridges 252a, 252b are positioned so that they are at the same position in the depth direction of the fitting groove 25 (the left-right direction in Figures 4 and 8).

The bottom surface 254 in the fitting groove 25 is formed as a substantially flat surface. However, from the bottom surface 254 to the inner surfaces 251a and 251b, inclined surfaces 255a and 255b are formed continuously on the indoor and outdoor sides, respectively. The indoor side inclined surface 255a continues to the base of the indoor side protrusion 252a. In contrast, the outdoor side inclined surface 255b does not continue to the base of the outdoor side protrusion 252b, and has a predetermined gap S between the protrusion 252b. Of the inclined surfaces 255a and 255b, the outdoor side inclined surface 255b mainly functions as a guide surface that guides the rotation of the vertical attachment 42 when the vertical attachment 42 is rotated and removed from the fitting groove 25. The fitting groove 26 arranged in the resin vertical frame 242 also has the same structure as the fitting groove 26 shown in Figures 4 and 8.

The configuration of the fitting groove 26 will be described with reference to Figures 5, 6, and 9. Figures 5 and 6 show the vertical attachment 42 attached to the fitting grooves 26 of the upper resin horizontal frame 212 and the lower resin horizontal frame 222, respectively. Figure 9 shows the vertical attachment 42 being attached to the fitting groove 26 of the lower resin horizontal frame 222.

The fitting groove 26 is a recessed groove capable of accommodating the horizontal attachment 43. As shown in FIG. 9, the inner surfaces 261a, 261b arranged on the indoor and outdoor sides of the fitting groove 26 have ridges 262a, 262b extending along the length direction, which protrude and face each other, similar to the fitting groove 25, narrowing the entrance of the fitting groove 26. The tip surfaces 263a, 263b of the ridges 262a, 262b are tapered and widen toward the outside of the fitting groove 26. The ridges 262a, 262b are arranged so that they are positioned at the same position in the depth direction of the fitting groove 26 (the vertical direction in FIGS. 5, 6, and 9).

The bottom surface 264 in the fitting groove 26 is formed as a substantially flat surface. As shown in FIG. 9, the fitting groove 26 of the resin lower horizontal frame 222 has inclined surfaces 265a, 265b formed continuously from the bottom surface 264 to the inner surfaces 261a, 261b on the indoor and outdoor sides, respectively. Of the inclined surfaces 265a, 265b, the outdoor side inclined surface 265b mainly functions as a guide surface that guides the tooth 412a side of the tape portion 412 to be smoothly wound toward the indoor side when the tape portion 412 on the side of the mesh portion 41 inserted into the fitting groove 26 is wound and engaged by the horizontal attachment 43.

The fitting groove 26 of the upper resin horizontal frame 212 also has a pair of protrusions 262a, 262b on the inner surfaces 261a, 261b, similar to the fitting groove 26 shown in Figures 6 and 9. The fitting groove 26 of the upper resin horizontal frame 212 does not have inclined surfaces 265a, 265b, as shown in Figures 3 and 5. However, the fitting groove 26 of the upper resin horizontal frame 212 may also have the same structure as the fitting groove 26 shown in Figures 6 and 9.

(Vertical attachment configuration)
Next, the configuration of the vertical attachments 42 will be described with reference to Fig. 8. The left and right vertical attachments 42 have the same structure. Therefore, the following will describe the vertical attachments 42 that are attached to the fitting grooves 25 of the vertical resin frame 232.

The vertical attachment 42 has a pair of side plates 421a, 421b that are arranged on the indoor and outdoor sides of the screen door 4, respectively, and a bottom plate 422 that connects the ends of the side plates 421a, 421b, and is formed in a roughly U-shape when viewed from the side. The outer surfaces extending from the side plates 421a, 421b to the bottom plate 422 are smooth arc surfaces 423a, 423b, respectively.

The indoor side plate 421a extends further toward the mesh body 411 than the outdoor side plate 421b. This forms an integral push-in portion 424 that is used to push the vertical attachment 42 with a finger when removing it from the fitting groove 25. As shown in FIG. 4, this push-in portion 424 protrudes slightly toward the outside of the fitting groove 25 when the vertical attachment 42 is fitted into the fitting groove 25.

On the inner surface of the side plate portion 421a on the indoor side, a first protrusion portion 425 is formed along the length direction of the vertical attachment 42. The first protrusion portion 425 protrudes from the side plate portion 421a toward the side plate portion 421b on the outdoor side, leaving a small gap between them. On the inner surface of the bottom plate portion 422, a second protrusion portion 426 is formed along the length direction of the vertical attachment 42. The second protrusion portion 426 protrudes from the bottom plate portion 422 toward the first protrusion portion 425, leaving a small gap between them. As a result, a locking portion 427 consisting of a space surrounded by the side plate portion 421a, the bottom plate portion 422, the first protrusion portion 425, and the second protrusion portion 426 is formed on the inside of the vertical attachment 42.

The gap between the first protrusion 425 and the second protrusion 426 is large enough that the tape portion of the tape section 412 of the net section 41 can be inserted, but the teeth 412a cannot pass through. Therefore, when the teeth 412a of the tape section 412 on the vertical side of the net section 41 are accommodated in the locking section 427 from one end of the vertical attachment 42 in the length direction, and the tape section 412 is inserted so that the net section main body 411 side is pulled out from between the first protrusion 425 and the side plate section 421b on the outside of the vertical attachment 42, the teeth 412a are locked in the locking section 427. As a result, the vertical attachment 42 is attached in an engaged state to the vertical side edge of the net section 41.

A pair of protrusions 428a, 428b extending along the length direction are formed on the outer surfaces of the side plate portions 421a, 421b of the vertical attachment 42. The width dimension between the side plate portions 421a, 421b of the vertical attachment 42 is the same as or slightly smaller than the distance between the protrusions 252a, 252b in the fitting groove 25, and the width dimension between the protrusions 428a, 428b of the vertical attachment 42 is formed slightly larger than the distance between the protrusions 252a, 252b in the fitting groove 25. Therefore, when the vertical attachment 42 is inserted into the fitting groove 25, the protrusions 428a, 428b elastically overcome and engage the protrusions 252a, 252b in the fitting groove 25. As a result, the vertical attachment 42 is fitted and held in the fitting groove 25.

The distance from the bottom plate portion 422 to the indoor side protrusion 428a is formed to be slightly shorter than the distance from the bottom surface 254 in the fitting groove 25 to the indoor side protrusion 252a. In other words, when the vertical attachment 42 is inserted into the fitting groove 25, the indoor side protrusion 428a elastically overcomes the indoor side protrusion 252a in the fitting groove 25 and at almost the same time, the bottom plate portion 422 abuts against the bottom surface 254 in the fitting groove 25. As a result, the indoor side protrusion 428a is engaged with the indoor side protrusion 252a in the fitting groove 25.

In contrast, the distance from the bottom plate 422 to the protrusion 428b on the outdoor side is shorter than the distance from the bottom plate 422 to the protrusion 428a on the indoor side. That is, the position of the protrusion 428b on the outdoor side is shifted by a shift amount D toward the bottom plate 422 side of the vertical attachment 42 with respect to the position of the protrusion 428a on the indoor side. Therefore, when the vertical attachment 42 is inserted into the fitting groove 25, the protrusion 428b on the outdoor side elastically overcomes the protrusion 252b of the fitting groove 25 before the protrusion 428a on the indoor side. After that, when the vertical attachment 42 is inserted further, the bottom plate 422 abuts against the bottom surface 254. At this time, the protrusion 428b on the outdoor side is positioned away from the protrusion 252b on the outdoor side in the fitting groove 25 toward the bottom surface 254.

The entire vertical attachment 42 in this embodiment is formed from a material that is harder than the horizontal attachment 43, specifically the attachment body 44 described below. Therefore, it can be firmly attached to the fitting groove 25. There is no particular restriction on the specific material from which the vertical attachment 42 is formed, and it may be a resin such as polyvinyl chloride or a metal such as aluminum.

(Horizontal attachment configuration)
Next, the configuration of the horizontal attachment 43 will be described with reference to Figures 9 to 14. The horizontal attachments 43, 43 arranged above and below the screen door 4 have the same structure. Therefore, the following describes the horizontal attachment 43 arranged on the resin lower horizontal frame 222. The horizontal attachment 43 has an attachment main body 44 and a removal member 45 that is attached to the attachment main body 44.

The attachment body 44 is a part that fixes the upper and lower edges of the mesh part 41 to the frame body 2 by fitting into the fitting groove 26. The attachment body 44 has a top plate part 441 and an engagement part 442 that protrudes from the back side of the top plate part 441.

The top plate portion 441 is made of a horizontally long rectangular flat plate having the same shape and size as the opening shape of the fitting groove 26. The top plate portion 441 is arranged on the surface side of the attachment body 44, that is, on the side facing the outside of the fitting groove 26 when the attachment body 44 is fitted into the fitting groove 26. The top plate portion 441 is formed of, for example, a resin such as hard polyvinyl chloride or a metal such as aluminum, and maintains the overall shape of the horizontal attachment 43. As shown in FIG. 10, an attachment hole 44a for attaching a removal member 45 described later is formed in the approximate center of the top plate portion 441. The attachment hole 44a is formed in a long slit shape along the length direction of the top plate portion 441. The attachment hole 44a penetrates the engagement portion 442 and opens between a pair of legs 442a, 442a of the engagement portion 442.

The engagement portion 442 is formed from a resin such as polyvinyl chloride that is softer than the top plate portion 441, and has a pair of legs 442a, 442a. This gives the engagement portion 442 an approximately C-shaped cross section that opens toward the side opposite the top plate portion 441. The pair of legs 442a, 442a are disposed on the outdoor side and indoor side of the attachment body 44, respectively, and extend along the length of the horizontal attachment 43. The mounting hole 44a penetrates from the top plate portion 441 to the engagement portion 442.

The legs 442a each have a protrusion 442b formed integrally therewith and facing outward. The width dimension of the pair of protrusions 442b, 442b is slightly larger than the distance between the pair of ridges 262a, 262b in the fitting groove 26. Therefore, when the horizontal attachment 43 is inserted into the fitting groove 26, the protrusions 442b, 442b elastically overcome and engage the ridges 262a, 262b in the fitting groove 26. As a result, the horizontal attachment 43 fitted into the fitting groove 26 is held within the fitting groove 26.

The removal member 45 is a hard part attached to the top plate portion 441 so as to protrude from the surface of the top plate portion 441 of the attachment body 44. More specifically, the removal member 45 is composed of a base member 451 and a cover member 452. The removal member 45 is attached to the attachment body 44 by clamping the attachment body 44 between the base member 451 and the cover member 452. More specifically, the base member 451 is inserted into the mounting hole 44a from the back side of the attachment body 44, specifically, between the pair of legs 442a, 442a, and protrudes from the mounting hole 44a to the surface of the top plate portion 441. The cover member 452 is attached to the base member 451 protruding from the mounting hole 44a so as to surround the surface side of the top plate portion 441.

As shown in Figures 11, 13, and 14, the base member 451 integrally includes a base 451a, a protruding plate portion 451b protruding from the base 451a, and a pair of engaging claw portions 451d, 451d. The base 451a, the protruding plate portion 451b, and the engaging claw portions 451d are formed of a resin that is harder than the engaging portion 442 of the horizontal attachment 43.

The base 451a is a rectangular parallelepiped that is long along the extension direction of the horizontal attachment 43. The base 451a can be positioned between the pair of legs 442a, 442a, but has a length and width that is such that it cannot be inserted through the mounting hole 44a.

The protruding plate portion 451b rises in a plate shape from approximately the center of the base portion 451a. The protruding plate portion 451b is formed so that it can be inserted through the mounting hole 44a. A number of ribs 451c extending in the height direction are provided on both side surfaces of the protruding plate portion 451b facing the indoor/outdoor direction. The protruding plate portion 451b constitutes a penetration portion in the base member 451 that is inserted into the mounting hole 44a.

The pair of engaging claws 451d, 451d rise from the base 451a so as to sandwich the protruding plate portion 451b in the longitudinal direction of the base 451a. The claws 451e, 451e of the engaging claws 451d, 451d are provided facing the side opposite to the side on which the protruding plate portion 451b is arranged. The engaging claws 451d, like the protruding plate portion 451b, are formed so as to be able to pass through the mounting hole 44a. The engaging claws 451d, 451d also constitute insertion portions in the base member 451 that are inserted into the mounting hole 44a.

As shown in Figures 12, 13 and 14, the cover member 452 is a block-shaped knob part made of the same hard resin as the base member 451. The bottom surface 452b of the cover member 452 is large enough to completely cover the mounting hole 44a of the attachment body 44. The thickness of the cover member 452 in the indoor/outdoor direction is approximately equal to the width of the attachment body 44 in the indoor/outdoor direction.

The cover member 452 has a storage groove 452a that accommodates the protruding plate portion 451b and the engaging claw portions 451d, 451d, which are the insertion portions of the base member 451. The storage groove 452a opens to the bottom surface 452b of the cover member 452. As shown in FIG. 14, the opening length of the storage groove 452a along the extension direction of the horizontal attachment 43 is slightly shorter than the distance between the claw portions 451e, 451e of the pair of engaging claw portions 451d, 451d of the base member 451. The groove width of the storage groove 452a along the indoor/outdoor direction is approximately equal to the thickness of the protruding plate portion 451b of the base member 451.

As shown in FIG. 13, the cover member 452 accommodates the protruding plate portion 451b and the engaging claw portions 451d, 451d of the base member 451 that protrude from the surface of the attachment body 44 from the surface side of the attachment body 44, i.e., the top plate portion 441 side, in the accommodation groove 452a. In this way, the cover member 452 clamps the base member 451 from the indoor/outdoor direction.

As shown in FIG. 14, a pair of protrusions 452d, 452d protruding downward from the ceiling portion 452c are provided inside the accommodation groove 452a of the cover member 452. The protrusions 452d, 452d sandwich the protruding plate portion 451b of the base member 451 accommodated in the accommodation groove 452a from the longitudinal direction of the protruding plate portion 451b. Furthermore, engagement holes 452e, 452e communicating with the accommodation groove 452a are provided on both end faces in the longitudinal direction of the cover member 452. The claw portions 451e, 451e of the engagement claw portions 451d, 451d elastically accommodated in the accommodation groove 452a are accommodated in the engagement holes 452e, 452e and engage with the step portions 452f, 452f of the engagement holes 452e, 452e. As a result, the cover member 452 is attached to the base member 451 by engaging the engagement claws 451d, 451d.

The cover member 452 is attached to the base member 451 to form a lateral attachment 43 having a detachment member 45. The detachment member 45 is attached to the attachment body 44 by clamping the attachment body 44 between the base 451a of the base member 451 and the bottom surface 452b of the cover member 452.

(How to install and remove screen doors)
Next, a method of attaching and detaching the screen door 4 to the frame body 2 will be described. When attaching the screen door 4 to the frame body 2, as shown in FIG. 7, the vertical attachment 42 attached to the screen part 41 in advance is fitted into the fitting groove 25, and then the horizontal attachment 43 is fitted into the fitting groove 26. In detail, as shown in FIG. 8, the vertical attachment 42 attached to the screen part 41 is inserted into the fitting grooves 25 of the resin vertical frames 232 and 242 with the side plate part 421a having the pushing part 424 positioned on the indoor side. Then, as shown in FIG. 9, the attachment body 44 is inserted into the fitting groove 26 into which the tape part 412 on the side of the screen part 41 is inserted, thereby attaching the horizontal attachment 43 to the fitting groove 26. The horizontal attachment 43 is inserted into the fitting groove 26 while the attachment body 44 wraps the tape part 412 inserted into the fitting groove 26. As a result, the four peripheral edges of the mesh portion 41 of the screen door 4 are fixed to the frame body 2, and the screen door 4 is stretched across the frame body 2.

When removing the screen door 4, the horizontal attachment 43 is removed from the fitting groove 26 in the reverse order to the above, and then the vertical attachment 42 is removed from the fitting groove 25. In detail, as shown in FIG. 15, the user presses the removal member 45 of the horizontal attachment 43 with a finger from the inside of the room toward the outside of the room, tilting the horizontal attachment 43 toward the outside of the room. This releases the engagement between the engagement portion 442 of the attachment body 44 and the pair of protrusions 262a, 262b in the fitting groove 26, and the horizontal attachment 43 is easily removed from the fitting groove 26.

When removing the lateral attachment 43 from the fitting groove 26, the user may either tilt the removal member 45 of the lateral attachment 43 toward the inside of the room, or pick up the removal member 45 of the lateral attachment 43 and pull it upward.

After the upper and lower horizontal attachments 43 are removed from the fitting groove 26, the vertical attachment 42 is removed from the fitting groove 25. In detail, first, the push-in portion 424 of the vertical attachment 42, which protrudes slightly from the fitting groove 25, is pushed with a finger in the X1 direction toward the outside of the room (FIG. 16A). This causes the vertical attachment 42 to start rotating in the X2 direction within the fitting groove 25 (FIG. 16B). At this time, the arc surface 423b on the outside of the room of the vertical attachment 42 abuts against the inclined surface 255b on the outside of the room in the fitting groove 25.

Then, the inclined surface 255b in the fitting groove 25 becomes a guide surface, and the vertical attachment 42 further rotates in the X2 direction while the arc surface 423b is guided by this inclined surface 255b. This allows the vertical attachment 42 to rotate smoothly without rattling in the fitting groove 25. Because the horizontal attachment 43 has already been removed, the horizontal attachment 43 does not interfere with the rotation of the vertical attachment 42 in the X2 direction.

When the vertical attachment 42 rotates in this manner, the projection 428a on the indoor side of the vertical attachment 42 easily and elastically overcomes the protruding stripe 252a on the indoor side within the fitting groove 25, disengaging it. The vertical attachment 42 is then removed from the fitting groove 25 by pulling it out in the X3 direction away from the fitting groove 25 (Figure 16C). This allows the screen door 4 to be removed from the frame 2.

(Effects of this embodiment)
Next, the effect of this embodiment will be described. The attachment body 44 of the horizontal attachment 43 of this embodiment has an attachment hole 44a for attaching the removal member 45. The removal member 45 is composed of a base member 451 that is inserted into the attachment hole 44a from the back side of the attachment body 44, and a cover member 452 that is attached to surround the base member 451 from the front side of the attachment body 44. The cover member 452 abuts against the front surface of the attachment body 44, thereby sandwiching the attachment body 44 between the base member 451. This allows the user to easily remove the horizontal attachment 43 from the fitting groove 26 without using a removal tool, for example by pressing the removal member 45 of the horizontal attachment 43 with a finger. The force applied to the removal member 45 when removing the horizontal attachment 43 is distributed over the entire bottom surface 452b of the cover member 452 that abuts against the front surface of the attachment body 44. Therefore, there is no risk of the force applied to the removal member 45 concentrating on the mounting hole 44a, causing whitening or damage to the periphery of the mounting hole 44a. As shown in Fig. 15, the force applied to the removal member 45 acts on the outermost part F of the attachment body 44. Therefore, the lateral attachment 43 can be easily tilted and removed from the fitting groove 26 with little force.

The base member 451 of this embodiment has a protruding plate portion 451b. The cover member 452 has an accommodation groove 452a that accommodates the protruding plate portion 451b and clamps it from the indoor/outdoor direction. This allows the base member 451, which clamps the attachment main body 44, and the cover member 452 to be firmly integrated.

In this embodiment, multiple ribs 451c extending in the height direction are provided on both sides of the protruding plate portion 451b facing the indoor/outdoor direction. This allows the protruding plate portion 451b to firmly withstand the force acting through the cover member 452 when removing the cover member.

The base member 451 of this embodiment has a pair of engaging claws 451d, 451d. The cover member 452 has a pair of engaging holes 452e, 452e that engage with the engaging claws 451d, 451d. This allows the base member 451 and the cover member 452 to be easily attached.

(Other embodiments of the removal member)
17 and 18 show a removal member 46 according to another embodiment. The removal member 46 is made of one part, which is different from the removal member 45 described above, which is made of two parts, a base member 451 and a cover member 452.

More specifically, the removal member 46 has a base 461 and a protruding plate portion 462 that protrudes from the base 461. The base 461 and the protruding plate portion 462 are formed from the same hard resin as the base 451a and the protruding plate portion 451b of the base member 451 of the removal member 45 described above, and have the same function as the base 451a and the protruding plate portion 451b.

On both sides of the protruding plate portion 462 facing the indoor/outdoor direction, protrusions 462a, 462a protrude. As shown in FIG. 18, when the protruding plate portion 462 is inserted into the mounting hole 44a from the back side of the attachment body 44, the pair of protruding portions 462a, 462a engage with the periphery of the mounting hole 44a from the front side of the attachment body 44. This allows the removal member 46 to be detachably attached to the attachment body 44. The protruding plate portion 462 protrudes from the mounting hole 44a to the front side of the attachment body 44. Therefore, when removing the horizontal attachment 43, the user can easily remove the protruding plate portion 462 from the fitting groove 26 by pressing it with a finger, as with the removal member 45.

In each of the above embodiments, the removal members 45, 46 are provided only on the horizontal attachment 43. However, the configuration of the horizontal attachment 43 having the removal members 45, 46 and the fitting groove 26 can also be applied to the vertical attachment. Furthermore, the configuration of the horizontal attachment 43 having the removal members 45, 46 and the fitting groove 26 can also be applied to both the vertical attachment and the horizontal attachment.
