Description

The present invention relates to a support structure that supports a screen door on a frame.

Some fixtures are equipped with what are known as fixed screen doors. Fixed screen doors have a screen installed inside a screen frame that is roughly the same size as the frame. A structure for supporting a fixed screen on a frame is described, for example, in Patent Document 1. That is, in Patent Document 1, an axis rod is provided on the frame, and a cylinder is provided on the screen, and the screen is supported on the frame by fitting the cylinder onto the axis rod from above.

JP 2001-193372 A

The shaft rods and cylinders used in the support structure described above have their axes extending vertically. For this reason, when supporting a screen on the frame, it is necessary to slide the screen downward while bringing it close to a part that is above the frame. However, there are often protrusions such as eaves around the frame when outdoors, and often a protruding frame when indoors, making it difficult to attach and remove the screen.

In view of the above, the present invention aims to provide a support structure for a screen door that allows the screen door to be attached and detached regardless of the installation condition of the frame body to which it is attached.

In order to achieve the above-mentioned object, the support structure for a screen door according to the present invention is a structure for supporting a screen door on a frame body, wherein a hook member having a hook portion extending along a projection direction is attached to either one of the frame material constituting the frame body or the screen door frame material constituting the screen door, and a curved end portion is provided at a tip portion of the hook portion, and the other of the frame material or the screen door frame material is provided with a hook receiving portion which is capable of abutting the curved end portion of the hook portion when the screen door is placed on the frame body , and which limits the screen door from moving downward and out-of-plane relative to the frame body when it abuts against the curved end portion of the hook portion, wherein the hook receiving portion is constructed by attaching a separately molded hook receiving member to the other of the frame material or the screen door frame material, and wherein the hook receiving member has a hook receiving surface which is inclined so that the height gradually varies toward the projection direction, and wherein the hook receiving portion is constructed by providing a notch in the hook receiving surface into which the hook portion can be inserted .

According to the present invention, by moving the screen along the extension direction of the hook portion, the curved end portion can come into contact with the hook receiving portion of the frame body, so it is possible to attach and detach the screen to and from the frame body even in situations where there are protrusions such as eaves or frames around the frame body.

(Embodiment 1)
1 to 5 show a fitting in which a screen door 20 is supported on a frame body 10 by applying a support structure according to the first embodiment of the present invention. The fitting exemplified here is called a horizontal sliding window, and opens so that a shoji screen 30 protrudes outward toward the outside of the room relative to the frame body 10. The frame body 10 is constructed by framing an upper frame 11, a lower frame 12, and left and right vertical frames 13 on all four sides. The shoji screen 30 is constructed by attaching an upper frame 32, a lower frame 33, and left and right vertical frames 34 to the four sides of a rectangular surface material 31 such as double-glazed glass, and is formed to a size that can close the frame body 10. The upper frame 11, the lower frame 12, and the left and right vertical frames 13 (hereinafter, these are collectively referred to as frame materials) that constitute the frame body 10 are each constructed with an outer frame component 10A arranged on the outside of the room and an inner frame component 10B arranged on the inside of the room. The outer frame component 10A is an extrusion made of a metal such as an aluminum alloy, and the inner frame component 10B is an extrusion made of a resin. The outer frame component 10A and the inner frame component 10B are each configured to have a substantially uniform cross-sectional shape over their entire length along the longitudinal direction. The frame members 11, 12, and 13 are integrally configured by engaging the outer frame component 10A and the inner frame component 10B with each other, and are attached to the frame B via each of the outer frame components 10A.

Similarly, the upper frame 32, lower frame 33, and left and right vertical frames 34 (hereinafter collectively referred to as frame materials) that make up the shoji screen 30 are each composed of an outer frame component 30A arranged on the outside of the room and an inner frame component 30B arranged on the inside of the room. The outer frame component 30A is an extruded material molded from a metal such as an aluminum alloy, and the inner frame component 30B is an extruded material molded from a resin. These outer frame component 30A and inner frame component 30B are each configured to have a substantially uniform cross-sectional shape along their entire length. The frame components 32, 33, and 34 are integrally constructed by engaging the outer frame component 30A and inner frame component 30B with each other, and accommodate the edge of the surface material 31 between them.

The inner frame component 10B constituting the upper frame 11 and the left and right vertical frames 13 has a hollow portion 10c on the inner periphery of each, and a frame support piece portion 10d is provided on the outer periphery of the hollow portion 10c toward the room. The hollow portion 10c is the portion that protrudes most inwardly in the upper frame 11 and the left and right vertical frames 13, and forms an inner visible surface 10e at each protruding end, and an outer visible surface 10f on the part that faces the outside of the room. The inner visible surface 10e is a flat surface that extends along the visible direction. The outer visible surface 10f is a flat surface that extends along the visible direction and is configured to face the outer periphery of the shoji screen 30 when the shoji screen 30 is closed. The frame support piece portion 10d is a thin plate-like member that extends along the visible direction. As is clear from the figure, the inner frame component 10B is attached to the frame B via the frame G by screwing the frame support piece 10d into the frame G. The frame G is provided around the four perimeters of the inner surface of the opening in the frame B that faces the interior, and is arranged to protrude further into the interior than the frame body 10.

In contrast, the inner frame component 10B that constitutes the lower frame 12 is provided with an inner frame body 10g, a frame support piece 10h, and an engagement piece 10j. The inner frame body 10g is a flat plate extending in the front direction. This inner frame body 10g is the part where the operating handle H for opening and closing the shoji 30 is attached to the front surface facing the room. The frame support piece 10h, like that provided on the inner frame component 10B of the upper frame 11, is a thin plate and extends from the edge on the outer periphery of the inner frame body 10g into the room along the front direction. The engagement piece 10j is provided so as to extend from the part on the inner periphery of the inner frame body 10g to the inner periphery, and is configured to have a plate thickness greater than that of the inner frame body 10g.

The screen door 20 attached to the frame 10 described above is constructed by attaching the upper screen door frame 22, the lower screen door frame 23, and the left and right screen door vertical frames 24 (hereinafter collectively referred to as screen door frame materials) to the four periphery of the rectangular screen 21. The screen door frame materials 22, 23, and 24 are each extruded shapes formed from metals such as aluminum alloys, and are configured to have a substantially uniform cross-sectional shape along their entire length. In the screen door 20 of this embodiment 1, the screen door frame materials 22, 23, and 24 are each hollow cylindrical. The external dimensions of the screen door 20 are set to a size that allows the outer peripheral edge to simultaneously abut the visible surfaces of the four inner frame components 10B that make up the four periphery of the frame 10.

Corner blocks 25 made of resin are provided at the four corners of the screen door 20. The corner blocks 25 are L-shaped with fitting protrusions 25b on two adjacent sides of a rectangular block body 25a, as shown in FIG. 6, and are arranged at the four corners of the screen door 20 by fitting the ends of the upper screen frame 22, the lower screen frame 23, and the left and right screen vertical frames 24 into the respective fitting protrusions 25b. The block body 25a of the corner blocks 25 is provided with engaging members 25c. The engaging members 25c move between a state in which they protrude from the side of the block body 25a as shown in FIG. 6(a) and a state in which they retract into the inside of the block body 25a as shown in FIG. 6(b) by operating an operating portion 25d provided on the surface of the block body 25a. Although not shown in the figure, a latch mechanism capable of maintaining the engaging member 25c in a protruding state is provided inside the block body 25a. This corner block 25 is provided on all four sides of the screen door 20 so that the engaging member 25c can protrude upward from the screen door upper frame 22 of the screen door 20 and protrude downward from the screen door lower frame 23. As shown in Figure 5, a gap 25e equivalent to the plate thickness of the engaging piece 10j provided on the inner frame component 10B of the bottom frame 12 is provided between the engaging member 25c and the block body 25a.

These corner blocks 25 can maintain the screen 20 attached to the frame body 10 by placing the screen 20 on the indoor side of the frame body 10 and protruding the respective engagement members 25c to the outer periphery. That is, in the two corner blocks 25 provided at the lower corners of the screen 20, when the engagement members (lower engagement portions) 25c are protruded, they can be engaged with the engagement piece portions 10j of the lower frame 12, making it possible to restrict the downward movement of the screen bottom frame 23 relative to the lower frame 12 of the frame body 10 and the movement in the out-of-plane direction along the projection direction. Meanwhile, the upper frame 11 of the frame body 10 has engagement holes 10k in the hollow portions 10c of the inner frame components 10B corresponding to the engagement members 25c. As a result, when the engaging member 25c is protruded upward with the screen door upper frame 22 in contact with the visible surface of the upper frame 11, the engaging member 25c fits into the engaging hole 10k, making it possible to restrict the out-of-plane movement of the screen door upper frame 22 in the visible direction relative to the upper frame 11 of the frame body 10.

Furthermore, a hook member 40 is attached to each of the left and right screen frame stiles 24 of the screen 20, and a hook receiving member 50 is attached to each of the left and right vertical frames 13 of the frame 10. These hook members 40 and hook receiving members 50 are formed from metal plates separate from the screen frame stiles 24 and vertical frames 13, and are disposed in the upper part of the frame 10 and screen 20, particularly in this embodiment 1, at a portion that is approximately 1/6 of the top of the overall height of the frame 10 and screen 20, as shown in Figure 4.

The hook member 40 has a common configuration on the left and right sides, and as shown in FIG. 7, is integrally formed with a hook mounting plate portion 41 having a substantially rectangular flat plate shape, a hook portion 42 that extends from one end of the hook mounting plate portion 41, bending or curving in a direction substantially perpendicular to the hook, and a hook abutment portion (curved end portion) 43 that extends from the extending end portion of the hook portion 42, bending or curving in a direction substantially perpendicular to the hook. In the illustrated example, the hook mounting plate portion 41, hook portion 42, and hook abutment portion 43 are all configured to have the same width. The extension direction of the hook abutment portion 43 is opposite to the extension direction of the hook mounting plate portion 41 with respect to the hook portion 42.

As shown in Figures 2 to 5, the hook member 40 is fixed to the exterior-facing surface 24a of the screen stile 24 via the hook mounting plate 41 with the hook portion 42 positioned below the hook mounting plate 41 and extending approximately horizontally along the projection direction. The hook member 40 can be fixed to the screen stile 24, for example, by screwing a mounting screw into the screen stile 24 via the hook mounting plate 41. A metal plate 44 is provided as a back plate at the portion inside the screen stile 24 where the mounting screw is screwed.

The hook receiving member 50 is symmetrical on the left and right, and is formed integrally with a flat receiving attachment plate portion 51 and a receiving surface plate portion (hook receiving surface) 52 that extends from one end of the receiving attachment plate portion 51 and bends or curves in a direction approximately perpendicular to the receiving surface plate portion 52, as shown in FIG. 7. The receiving surface plate portion 52 has a square hole (notch) 52a formed therein, which is large enough to allow the hook portion 42 and the hook abutment portion 43 of the hook member 40 to pass through. The square hole 52a is a through hole that is a horizontally long rectangle, and is formed at a position that is approximately the center of the receiving surface plate portion 52. More specifically, the dimension of the square hole 52a along the long side is larger than the width of the hook portion 42 along the left and right sides. The dimension of the square hole 52a along the short side is formed to be approximately the same as the extension length of the hook abutment portion 43.

2 to 5, this hook receiving member 50 is fixed to the inner visible surface 10e of the vertical frame 13 via the receiving mounting plate 51 with the receiving surface plate 52 inclined gradually upward toward the outside, and the hook receiving portion 52A is formed below the square hole 52a, while the upward movement restricting portion 52B is formed above the square hole 52a. The hook receiving member 50 can be fixed to the vertical frame 13, for example, by screwing a mounting screw into the vertical frame 13 via the hook mounting plate 41. A metal plate 53 is provided as a back plate in the hollow portion 10c of the vertical frame 13 where the mounting screw is screwed. The position for fixing the hook receiving member 50 is set so that when the screen door 20 is placed in a substantially vertical direction with the lower engaging member 25c engaged with the engaging piece 10j of the lower frame 12 (hereinafter, this state will be referred to as "when the screen door 20 is placed in the mounting position"), the hook receiving portion 52A located below the square hole 52a on the receiving surface plate 52 will be in a position facing the hook abutment portion 43 of the hook member 40.

Here, the rectangular hole 52a formed in the receiving surface plate 52 of the hook receiving member 50 is formed so that the distance from the upward movement restricting portion 52B to the hook receiving portion 52A is approximately the same as the vertical dimension of the hook abutment portion 43. However, the hook receiving member 50 is fixed to the vertical frame 13 with the receiving surface plate 52 tilted. Therefore, when fixed to the vertical frame 13, the vertical dimension between the upward movement restricting portion 52B and the hook receiving portion 52A is slightly shorter than the dimension of the hook abutment portion 43. In this embodiment 1, when the screen door 20 is placed in the mounting position, the fixing positions of the hook member 40 and the hook receiving member 50 are adjusted in advance so that the upward movement restricting portion 52B is located slightly above the upper surface of the hook portion 42, and the hook receiving portion 52A is located slightly above the lower end of the hook abutment portion 43, and the hook portion 42 penetrates the receiving surface plate 52, as shown in FIG. 7(b).

To pass the hook portion 42 through the rectangular hole 52a of the hook receiving member 50, first, as shown on the right side of Fig. 5, the engaging members 25c of the two corner blocks 25 provided at the lower corners of the screen door 20 are protruded, while the engaging members (upper engaging members) 25c of the two corner blocks 25 provided at the upper corners of the screen door 20 are retracted. From this state, for example, the screen door 20 is placed in an oblique position, and the engaging members 25c at the lower corners are first engaged with the engaging pieces 10j of the bottom frame 12, as shown on the left side of Fig. 5. As described above, when the engaging members 25c at the lower corners are engaged with the engaging pieces 10j of the bottom frame 12, downward movement of the screen bottom sill 23 relative to the bottom frame 12 and movement in the out-of-plane direction along the projection direction are restricted, so if the position of the upper part of the screen 20 is changed so as to be closer to the frame body 10, the hook portion 42 of the hook member 40 provided on the screen 20 will move in the projection direction relative to the hook receiving member 50 of the frame body 10, and the hook portion 42 will be inserted into the square hole 52a of the hook receiving member 50. At that time, because the receiving surface plate portion 52 with the square hole 52a is inclined, even if there is some misalignment in height between the hook portion 42 and the square hole 52a, the receiving surface plate portion 52 can act as a guide and allow the hook portion 42 to be inserted into the square hole 52a. After the hook portion 42 passes through the corner hole 52a of the hook receiving member 50, the engaging members 25c of the two corner blocks 25 provided at the upper corners of the screen door 20 are moved upward so that they engage with the engaging holes 10k of the upper frame 11, and the screen door 20 is supported by the frame body 10.

Although not shown in the figure, it is also possible to pass the hook portion 42 through the rectangular hole 52a of the hook receiving member 50 by moving the screen door 20 in the forward direction while keeping all the upper and lower engaging members 25c in a retracted state and maintaining the screen door 20 in a vertical position. After the hook portion 42 passes through the rectangular hole 52a of the hook receiving member 50, the engaging members 25c can be operated to protrude, allowing the screen door 20 to be supported by the frame 10.

In either case, in the above-mentioned fittings, if the screen door 20 is moved relative to the frame body 10 along the extension direction of the hook portion 42, in other words, if the screen door 20 is moved in the forward direction, the hook abutment portion 43 will penetrate the square hole 52a and be able to abut against the hook receiving portion 52A. Therefore, even in a situation where the frame G is positioned protruding from the indoor side of the frame body 10, the screen door 20 can be easily attached and detached from the frame body 10 by operating it from the indoor side.

As described above, when the hook portion 42 penetrates the rectangular hole 52a of the hook receiving member 50, the hook receiving portion 52A is positioned slightly above the lower end of the hook abutment portion 43. Therefore, even if the operation of moving the upper engaging member 25c upward is forgotten when supporting the screen door 20 on the frame body 10, or even if the engaging member 25c protruding upward moves downward due to impact or vibration, the hook abutment portion 43 of the hook portion 42 abuts against the hook receiving portion 52A, so that the screen door 20 does not move downward relative to the frame body 10 or move in the outward direction toward the interior side, and it is possible to prevent the screen door 20 from falling off. Furthermore, since the upward movement restricting portion 52B is positioned slightly above the upper surface of the hook portion 42, the upward movement of the screen door 20 relative to the frame body 10 is restricted. This makes it possible to prevent, for example, the upper engaging member 25c from being pushed downward by the screen door 20 moving upward relative to the frame body 10.

(Embodiment 2)
In the above-mentioned embodiment 1, the screen door 20 is provided with the hook member 40, while the frame body 10 is provided with the hook receiving member 50, but as in embodiment 2 shown in Figures 8 to 10, it is also possible to configure the screen door 20 to have the hook receiving member 150, while the frame body 10 is provided with the hook member 140. Below, embodiment 2 will be described in detail, mainly focusing on the parts that differ from embodiment 1, and the same components as embodiment 1 will be described with the same reference numerals.

The hook member 140 provided on the frame body 10 has a symmetrical shape on the left and right, and is formed by integrally molding the hook mounting plate portion 141, the connecting plate portion 142, the hook portion 143, and the hook abutment portion (curved end portion) 144. The hook mounting plate portion 141 is a flat plate having a substantially rectangular shape. The connecting plate portion 142 is a flat plate extending from one side edge portion of the hook mounting plate portion 141, bending or curving in a substantially perpendicular direction. The extension length of the connecting plate portion 142 is greater than that of the hook mounting plate portion 141, and protrudes from one end portion of the hook mounting plate portion 141. The hook portion 143 is a flat plate extending from the edge portion of the connecting plate portion 142 protruding from the hook mounting plate portion 141, bending or curving in a substantially perpendicular direction. As is clear from the figure, hook portion 143 has a width approximately half that of connecting plate portion 142, and is provided at a position on the protruding edge of connecting plate portion 142 at a distance from hook mounting plate portion 141. The extension direction of hook portion 143 is the same direction as hook mounting plate portion 141 relative to connecting plate portion 142. Hook abutment portion 144 is a flat plate that extends from the extending edge of hook portion 143, bending or curving at an approximately right angle, and is configured to have the same width as hook portion 143. The extension direction of hook abutment portion 144 is the same direction as connecting plate portion 142 relative to hook portion 143.

The hook member 140 is fixed to the vertical frame 13 by screwing a mounting screw into the inner visible surface 10e of the vertical frame 13 via the hook mounting plate portion 141, with the hook portion 143 extending in the visible direction below the connecting plate portion 142 and the hook abutment portion 144 facing the interior side of the room. A metal plate 145 is provided as a back plate in the hollow portion 10c of the vertical frame 13 where the mounting screw is screwed.

The hook receiving member 150 has a common configuration on the left and right sides, and is integrally formed with a flat receiving attachment plate portion 151, a connecting plate portion 152 that extends from one end of the receiving attachment plate portion 151 at a substantially right angle and bent or curved, and a receiving surface plate portion (hook receiving surface) 153 that extends from one end of the connecting plate portion 152 at an angle and bent or curved. The receiving attachment plate portion 151 and the connecting plate portion 152 have substantially the same width, and the receiving surface plate portion 153 is configured to have a width larger than the receiving attachment plate portion 151 and the connecting plate portion 152. The receiving surface plate portion 153 has a square hole (notch) 153a formed in a size that allows the hook portion 143 and the hook abutment portion 144 of the hook member 140 to be inserted therethrough. The square hole 153a is a through hole that forms a horizontally elongated rectangular shape, and the dimension along the length is configured to be larger than the width along the left and right sides of the hook portion 143. The dimension along the short side of the rectangular hole 153a is formed to be approximately the same as the extension length of the hook abutment portion 144.

The hook receiving member 150 is fixed to the screen door vertical frame 24 by screwing a mounting screw into the facing surface 24a of the screen door vertical frame 24 facing the outside through the receiving mounting plate portion 151 with the receiving surface plate portion 153 inclined gradually upward toward the outside. The hook receiving member 150 in the state where it is fixed to the screen door vertical frame 24 forms a hook receiving portion 153A at the portion above the square hole 153a, and forms an upward movement restricting portion 153B at the portion below the square hole 153a. A metal plate 154 is disposed as a back plate at the portion inside the screen door vertical frame 24 where the mounting screw is screwed. The position where the hook receiving member 150 is fixed is set so that when the screen door 20 is placed in the above-mentioned mounting position, the hook receiving portion 153A located above the square hole 153a of the receiving surface plate portion 153 faces the hook abutment portion 144 of the hook member 140.

The rectangular hole 153a formed in the receiving plate 153 of the hook receiving member 150 is formed so that the distance from the hook receiving portion 153A to the upward movement restricting portion 153B is approximately the same as the vertical dimension of the hook abutment portion 144. However, the hook receiving member 150 is fixed to the vertical screen frame 24 with the receiving plate 153 tilted. Therefore, when fixed to the vertical screen frame 24, the vertical dimension between the upward movement restricting portion 153B and the hook receiving portion 153A is slightly shorter than the dimension of the hook abutment portion 144.

In this second embodiment, when the screen door 20 is placed in the mounting position, the fixed positions of the hook member 140 and the hook receiving member 150 are pre-adjusted so that the hook receiving portion 153A is positioned slightly below the upper edge of the hook abutment portion 144, and the upward movement restricting portion 153B is positioned slightly below the lower surface of the hook portion 143, and the hook portion 143 penetrates the receiving surface plate portion 153, as shown in the enlarged portion of FIG. 8.

When the hook portion 143 is to be inserted through the square hole 153a of the hook receiving member 150, the same operation as in the first embodiment may be performed. That is, if the screen door 20 is moved along the extension direction of the hook portion 143 relative to the frame body 10, in other words, if the screen door 20 is moved in the forward direction, the hook abutment portion 144 will penetrate the square hole 153a and be able to abut against the hook receiving portion 153A. Therefore, even if the frame G is arranged in a protruding state on the indoor side of the frame body 10, the screen door 20 can be easily attached and detached from the frame body 10 by operating it from the indoor side. When the hook portion 143 is inserted through the square hole 153a of the hook receiving member 150, the engaging members 25c of the corner blocks 25 provided at the four corners of the screen door 20 are moved outward, and the screen door 20 is supported by the frame body 10.

As described above, when the hook portion 143 penetrates the rectangular hole 153a of the hook receiving member 150, the hook receiving portion 153A is located slightly below the upper end of the hook abutment portion 144. Therefore, even if the upper engaging member 25c is forgotten to be moved upward when supporting the screen door 20 on the frame body 10, or even if the engaging member 25c protruding upward moves downward due to impact or vibration, the hook abutment portion 144 of the hook member 140 abuts against the hook receiving portion 153A, so that the screen door 20 does not move downward relative to the frame body 10 or move outward toward the interior side, and it is possible to prevent the screen door 20 from falling off. Furthermore, since the upward movement restricting portion 153B is located slightly below the bottom surface of the hook portion 143, the upward movement of the screen door 20 relative to the frame body 10 is restricted. This makes it possible to prevent a situation in which the upper engagement member 25c is pushed downward, for example, when the screen door 20 moves upward relative to the frame body 10.

(Embodiment 3)
In both the above-mentioned first and second embodiments, the hook receiving portions 52A, 153A are formed by providing square holes 52a, 153a in the hook receiving members 50, 150, but the present invention does not necessarily require the provision of closed notches such as square holes 52a, 153a. For example, as in the third embodiment shown in Figures 11 to 13, the hook receiving portion 253A may be formed by providing a notched groove (notch) 253a in the hook receiving member 250 so as to open to the side surface. Hereinafter, the third embodiment will be described in detail, mainly focusing on the parts that differ from the first embodiment, and the same components as those in the first embodiment will be described with the same reference numerals.

The hook member 240 provided on the frame body 10 has a symmetrical shape on the left and right, and is formed by integrally molding the hook mounting plate portion 241, the hook portion 242, and the hook abutment portion (bent end portion) 243. The hook mounting plate portion 241 is a flat plate having a substantially rectangular shape. The hook portion 242 is a flat plate extending from one end of the hook mounting plate portion 241, bending or curving in a substantially perpendicular direction, with only one side edge of the extending edge portion protruding and becoming wider. The hook abutment portion 243 is a flat plate extending from the wider protruding edge portion of the hook portion 242, bending or curving in a substantially perpendicular direction. The extension direction of the hook abutment portion 243 is the same as the extension direction of the hook mounting plate portion 241 with respect to the hook portion 242.

The hook member 240 is fixed to the vertical frame 13 by screwing a mounting screw into the inner visible surface 10e of the vertical frame 13 via the hook mounting plate portion 241, with the hook portion 242 extending in the forward direction below the hook mounting plate portion 241 and the hook abutment portion 243 facing the interior side of the room. A metal plate 244 is provided as a back plate in the hollow portion 10c of the vertical frame 13 where the mounting screw is screwed.

The hook receiving member 250 has a common configuration on the left and right sides, and is integrally formed with a flat receiving attachment plate portion 251, a connecting plate portion 252 that extends from one end of the receiving attachment plate portion 251, bending or curving at a substantially right angle, and a receiving surface plate portion (hook receiving surface) 253 that extends from one end of the connecting plate portion 252, bending or curving. The receiving attachment plate portion 251 and the connecting plate portion 252 have substantially the same width, and the receiving surface plate portion 253 is configured to have a width greater than the receiving attachment plate portion 251 and the connecting plate portion 252. The receiving surface plate portion 253 is formed with a notch groove 253a that is large enough to allow the hook portion 242 and hook abutment portion 243 of the hook member 240 to be inserted therethrough. The notch groove 253a is a through hole that has a horizontally long rectangular shape and is open on one side, and its dimension along the long side is larger than the width along the left and right sides of the hook portion 242. The dimension along the short side of the notch groove 253a is formed to be approximately the same as the extension length of the hook abutment portion 243.

This hook receiving member 250 is fixed to the screen door vertical frame 24 by screwing a mounting screw into the facing surface 24a of the screen door vertical frame 24 facing the outside through the receiving mounting plate portion 251 with the receiving surface plate portion 253 inclined gradually upward toward the outside and the notch groove 253a open to the outer periphery. When fixed to the screen door vertical frame 24, the hook receiving member 250 forms a hook receiving portion 253A at the portion above the notch groove 253a and forms an upward movement restricting portion 253B at the portion below the notch groove 253a. A metal plate 254 is provided as a back plate at the portion inside the screen door vertical frame 24 where the mounting screw is screwed.

The notch groove 253a formed in the receiving surface plate 253 of the hook receiving member 250 is formed so that the distance from the hook receiving portion 253A to the upward movement restricting portion 253B is approximately the same as the vertical dimension of the hook abutment portion 243. However, the hook receiving member 250 is fixed to the screen vertical frame 24 with the receiving surface plate 253 tilted. Therefore, when fixed to the screen vertical frame 24, the vertical dimension between the upward movement restricting portion 253B and the hook receiving portion 253A is slightly shorter than the dimension of the hook abutment portion 243.

In this third embodiment, when the screen door 20 is placed in the mounting position, the fixed positions of the hook member 240 and the hook receiving member 250 are pre-adjusted so that the hook receiving portion 253A is positioned slightly below the upper edge of the hook abutment portion 243, and the upward movement restricting portion 253B is positioned slightly below the lower surface of the hook portion 242, and the hook portion 242 penetrates the receiving surface plate portion 253, as shown in the enlarged portion of FIG. 11.

When the hook portion 242 is to be inserted through the notch groove 253a of the hook receiving member 250, the same operation as in the first embodiment may be performed. That is, if the screen door 20 is moved along the extension direction of the hook portion 242 relative to the frame body 10, in other words, if the screen door 20 is moved in the forward direction, the hook abutment portion 243 will penetrate the notch groove 253a and be able to abut against the hook receiving portion 253A. Therefore, even if the frame G is arranged in a protruding state on the indoor side of the frame body 10, the screen door 20 can be easily attached and detached from the frame body 10 by operating it from the indoor side. When the hook portion 242 is inserted through the notch groove 253a of the hook receiving member 250, the engaging members 25c of the corner blocks 25 provided at the four corners of the screen door 20 are moved outward, so that the screen door 20 is supported by the frame body 10.

As described above, when the hook portion 242 penetrates the notch groove 253a of the hook receiving member 250, the hook receiving portion 253A is located slightly below the upper end of the hook abutment portion 243. Therefore, even if the upper engaging member 25c is forgotten to be moved upward when supporting the screen door 20 on the frame body 10, or even if the engaging member 25c protruding upward moves downward due to impact or vibration, the hook abutment portion 243 of the hook member 240 abuts against the hook receiving portion 253A, so that the screen door 20 does not move downward relative to the frame body 10 or move outward toward the interior side, and it is possible to prevent the screen door 20 from falling off. Furthermore, since the upward movement restricting portion 253B is located slightly below the bottom surface of the hook portion 242, the upward movement of the screen door 20 relative to the frame body 10 is restricted. This makes it possible to prevent a situation in which the upper engagement member 25c is pushed downward, for example, when the screen door 20 moves upward relative to the frame body 10.

(Embodiment 4)
In the above-mentioned first to third embodiments, the hook receiving parts 52A, 153A, 253A are formed by attaching separate hook receiving members 50, 150, 250 to the frame material 13 or the screen door frame material 24, but this is not necessarily limited to this, and it is also possible to form the hook receiving parts by directly forming notches in the frame materials 11, 12, 13 or the screen door frame material 22, 23, 24. Figures 14 to 16 show a fourth embodiment of the present invention in which the hook receiving parts 24A are formed by directly forming square holes (notches) 24b in the left and right screen door vertical frames 24, respectively. Below, the fourth embodiment will be described in detail mainly in terms of the parts that differ from the first embodiment, and the same components as the first embodiment will be described by using the same reference numerals.

The hook member 340 provided on the frame body 10 has a symmetrical shape on the left and right, and is formed by integrally molding the hook mounting plate portion 341, the hook portion 342, and the hook abutment portion (curved end portion) 343. The hook mounting plate portion 341 is a flat plate having a substantially rectangular shape. The hook portion 342 is a flat plate extending from one end of the hook mounting plate portion 341 by bending or curving in a substantially perpendicular direction, and only one side edge of the extended edge portion protrudes and becomes wide. As is clear from the figure, the hook portion 342 of the fourth embodiment has a length approximately twice the width of the hook mounting plate portion 341. The hook abutment portion 343 is a flat plate extending from the wide protruding edge portion of the hook portion 342 by bending or curving in a substantially perpendicular direction. The extension direction of the hook abutment portion 343 is the same as the extension direction of the hook mounting plate portion 341 with respect to the hook portion 342.

The hook member 340 is fixed to the vertical frame 13 by screwing a mounting screw into the inner visible surface 10e of the vertical frame 13 via the hook mounting plate portion 341, with the hook portion 342 extending in the visible direction below the hook mounting plate portion 341 and the hook abutment portion 343 facing the interior side of the room. A metal plate 344 is provided as a back plate in the hollow portion 10c of the vertical frame 13 where the mounting screw is screwed.

The screen door vertical frame 24 arranged on the left and right of the screen door 20 has a square hole 24b on the visible surface 24a facing the outside of the room, and a hook receiving portion 24A is formed above the square hole 24b, and an upward movement restricting portion 24B is formed below the square hole 24b. The square hole 24b is rectangular in shape, and is formed so that the dimension along the left and right is larger than the width along the left and right of the hook portion 342, and the dimension along the top and bottom is slightly larger than the extension length of the hook abutment portion 343. The position of the square hole 24b is set so that when the screen door 20 is placed in the above-mentioned installation position, the hook receiving portion 24A located above the square hole 24b faces the hook abutment portion 343 of the hook member 340. More specifically, when the screen door 20 is placed in the mounting position, as shown in the enlarged portion of Figure 14, the fixed position of the hook member 340 and the formation position of the square hole 24b are adjusted in advance so that the hook receiving portion 24A is located slightly below the upper edge of the hook abutment portion 343, and the upward movement restricting portion 24B is located slightly below the lower surface of the hook portion 342, and the hook portion 342 is in a position penetrating the square hole 24b. Note that this square hole 24b does not penetrate the visible surface of the screen door vertical frame 24 that faces the room.

When the hook portion 342 is to be inserted through the square hole 24b of the screen frame 24, the same operation as in the first embodiment may be performed. That is, if the screen 20 is moved along the extension direction of the hook portion 342 relative to the frame body 10, in other words, if the screen 20 is moved in the forward direction, the hook abutment portion 343 will penetrate the square hole 24b and be able to abut against the hook receiving portion 24A. Therefore, even if the frame G is arranged in a protruding state on the indoor side of the frame body 10, the screen 20 can be easily attached and detached from the frame body 10 by operating it from the indoor side. When the hook portion 342 is inserted through the square hole 24b of the screen frame 24, the engaging members 25c of the corner blocks 25 provided at the four corners of the screen 20 are moved outward, so that the screen 20 is supported by the frame body 10.

As described above, when the hook portion 342 penetrates the square hole 24b of the screen door vertical frame 24, the hook receiving portion 24A located above the square hole 24b is located slightly below the upper end of the hook abutment portion 343. Therefore, even if the operation of moving the upper engaging member 25c upward is forgotten when supporting the screen door 20 on the frame body 10, or even if the engaging member 25c protruding upward moves downward due to impact or vibration, the hook abutment portion 343 of the hook member 340 abuts the hook receiving portion 24A, so that the screen door 20 does not move downward relative to the frame body 10 or move in the outward direction toward the inside of the room, and it is possible to prevent the screen door 20 from falling off. Furthermore, since the upward movement restriction portion 24B located below the square hole 24b is located slightly below the lower surface of the hook portion 342, the upward movement of the screen door 20 relative to the frame body 10 is restricted. This makes it possible to prevent a situation in which the upper engagement member 25c is pushed downward, for example, when the screen door 20 moves upward relative to the frame body 10.

Incidentally, when forming a hook receiving portion by providing a square hole, it does not necessarily have to be the screen door frame material 22, 23, 24, but it may be provided on the frame material 11, 12, 13. In this case, it is sufficient to provide a hook member with a curved end of the hook portion extending downward on the screen door frame material 22, 23, 24.

In the above-mentioned first to fourth embodiments, a horizontal sliding window is used as an example of a fixture that supports a screen door, but it can of course be applied to cases where other fixtures support a screen door as long as the fixture has a shoji screen attached to the frame so that it can be opened and closed. Also, although an example is given of a fixture that supports a screen door on the indoor side of the shoji screen, it can also be applied to a case where the screen door is supported on the outdoor side of the shoji screen. Furthermore, although an example is given of a frame material and a stile material that each have a metal part and a resin part, this is not necessarily limited to this. Furthermore, although the hook member and hook receiving part are provided on the vertical frame and vertical screen door stile that extend in the vertical direction, they may also be provided on the upper frame, the upper or lower screen door stile, or the lower screen door stile.

In addition, in the above-mentioned embodiments 1 to 4, the lower engagement portion is exemplified as one that protrudes below the screen door and engages with the lower frame, but the lower engagement portion may be provided so as to engage with the vertical frame at the lower part of the screen door. Note that the lower engagement portion that protrudes downward does not necessarily have to be in a retracted state. In addition, the upper engagement member is exemplified as one that protrudes above the screen door and engages with the upper frame, but the upper engagement member may be provided so as to engage with the vertical frame at the upper part of the screen door. Furthermore, the lower engagement portion and upper engagement member do not necessarily have to be provided on the screen door, but may be provided on the frame body.

Furthermore, in the above-mentioned embodiments 1 to 4, an upward movement regulating portion is provided, but it is not necessary to provide an upward movement regulating portion. Note that, when an upward movement regulating portion is provided, in the above-mentioned embodiments 1 to 3, it is provided integrally with the hook receiving member, but it is also possible to provide the upward movement regulating portion as a member separate from the hook receiving member.

As described above, the support structure for a screen door according to the present invention is a structure for supporting a screen door relative to a frame body, and is characterized in that a hook member having a hook portion extending along a projection direction is attached to either one of the frame material that constitutes the frame body or the screen door frame material that constitutes the screen door, and the hook portion has a curved end portion at its tip, and the other of the frame material or the screen door frame material is provided with a hook receiving portion that is capable of abutting the curved end portion of the hook portion when the screen door is placed on the frame body, and that when abutting the curved end portion of the hook portion, limits the screen door from moving downward and out-of-plane relative to the frame body.
According to this invention, when the screen is moved along the extension direction of the hook portion, the curved end portion is able to come into contact with the hook receiving portion of the frame body, so even in a situation where there are protrusions such as eaves or frames around the frame body, these do not become an obstacle and the screen can be attached and detached from the frame body. Moreover, when the operation to place the screen is performed from one surface side of the frame body, the curved end portion of the hook portion can come into contact with the hook receiving portion, so that the movement of the screen in the downward and out-of-plane directions relative to the frame body can be restricted. Therefore, since there is no need to perform the operation from the other surface side of the frame body, the operation of attaching and detaching the screen can be facilitated.

The present invention is further characterized in that, in the above-mentioned support structure for a screen door, the hook member is attached to either a frame material extending in the vertical direction on the frame body or a screen door frame material extending in the vertical direction on the screen door.
