Description

[Technical Field]

[0001] The present invention relates to a screen device for stretching a screen such as an insect net or a privacy sheet over a frame attached to an opening in a building, and to an attachment structure for the same. [Background technology]

[0002] It has been common practice to stretch screens such as insect nets and privacy sheets over frames attached to building openings. When stretching a screen over the frame in this way, a conventional method has been to fasten the peripheral edge of the screen together with a retaining member by pushing it into an engaging groove formed on the visible surface of the frame, as shown in Patent Document 1 and Figures 8 and 9, for example.

[0003] However, in this method, the screen and the pressing member are formed separately, and therefore, during the tensioning work, the screen and the pressing member may become misaligned, causing wrinkles or slack in the tensioned screen. Therefore, it is not necessarily easy to tension the screen in a taut state without causing wrinkles or slack within the frame, and a certain degree of skill is required.

[0004] Furthermore, as shown in Figures 8 and 9, in a building opening 100, a gap 130 is formed between a first frame body 110 for stretching a screen 105 and a second frame body (such as a sash frame or a glass shoji frame) 120 arranged adjacent to the first frame body 110 in the indoor / outdoor direction (forward direction).In order to prevent foreign objects such as insects from entering through this gap from the outside, it is necessary to provide a sealing member 115 such as mohair on the first frame body 110 that abuts against the second frame body 120.

[0005] As such, in the past, when installing a screen in an opening in a building, in addition to the screen and its frame, it was necessary to prepare the pressing member and sealing member separately, which tended to increase the number of parts and increase costs.

[0009] In the screen device, preferably, the holding frame is formed from an elastic material, and the connecting portion has a fixed portion fixed to the peripheral edge of the screen, and a tension generating portion connected to the outer end of the fixed portion, bent toward the second surface side relative to the fixed portion and extending outward, for applying elastic tension to the screen stretched on the first frame body, and the engaging holding portion is connected to the outer end of the tension generating portion.

[0010] Preferably, the engaging and holding portion has a base portion connected to the outer end of the tension generating portion, and the sealing portion has a spring portion protruding from the second surface side of the base portion and a sealing member connected to the tip of the spring portion. In this case, more preferably, the sealing member extends along the peripheral edge of the screen to which the holding frame is fixed and is formed in a strip shape convex in the direction of the protrusion of the spring portion. Even more preferably, a portion of the sealing member inward from a connection portion with the tip of the spring portion is connected to the base portion, and an outer end of the sealing member outward from the connection portion with the tip of the spring portion is a free end. More preferably, the engaging protrusion has a pillar portion whose base end is connected to the base portion and an engaging portion connected to the tip of the pillar portion for engaging with the engaging groove, and the engaging portion is formed by a pair of flanges protruding inward and outward from the tip of the pillar portion.

[0011] In addition, in order to solve the above-mentioned problems, the present invention provides a mounting structure for a screen device to an opening in a building, wherein a first frame body and a second frame body adjacent to each other along a front direction are attached to the opening in the building, and an engagement groove is recessed in the front surface of the first frame body facing the second frame body, and the screen device has a flexible rectangular screen and a retaining frame extending along the peripheral edge of the screen, and has a first surface and a second surface opposite thereto, and the retaining frame has a strip-shaped connecting portion whose inner portion is fixed to the peripheral edge of the screen and an engagement retaining portion connected to the outer end of the connecting portion, and the engagement retaining portion has an engagement protrusion erected on the first surface side and a seal portion formed on the second surface side, and the engagement protrusion of the engagement retaining portion engages with the engagement groove of the first frame body, causing the seal portion of the engagement retaining portion to abut against the second frame body.

[0012] In the mounting structure of the screen device, preferably, the holding frame is formed from an elastic material, and the connecting portion has a fixed portion fixed to the peripheral edge of the screen and a tension generating portion connected to the outer end of the fixed portion and bent toward the second surface side relative to the fixed portion and extending outward, the engaging holding portion is connected to the outer end of the tension generating portion, and the tension generating portion applies elastic tension to the screen stretched on the first frame body.

[0013] Preferably, the engaging and holding portion has a base portion connected to the outer end of the tension generating portion, and the sealing portion has a spring portion protruding from the second surface side of the base portion and a sealing member connected to the tip of the spring portion. In this case, more preferably, the sealing member extends along the peripheral edge of the screen to which the holding frame is fixed and is formed in a strip shape convex in the direction of the protrusion of the spring portion, and the surface of the sealing member facing the second frame abuts against the inside surface of the second frame. Even more preferably, a portion of the sealing member inward from the connecting portion with the spring portion is connected to the base portion, and an outer end of the sealing member outward from the connecting portion with the spring portion is a free end, so that the engagement between the engaging protrusion and the engaging groove can be released by gripping the sealing member from the free end side.

[0014] More preferably, the engaging protrusion has a pillar portion whose base end is connected to the base portion, and an engaging portion connected to the tip of the pillar portion for engaging with the engaging groove, the engaging groove being wider than the pillar portion of the engaging protrusion and narrower than the engaging portion, and having an introduction portion whose one end opens to the visible surface of the first frame body, and a storage portion whose other end opens and is wider than the introduction portion and the engaging portion, the engaging portion being formed by a pair of flange portions protruding inward and outward from the tip of the pillar portion, and these pair of flange portions are engaged around the opening of the introduction portion in the storage portion in a non-slip state.

[0015] Furthermore, in the mounting structure of the screen device, preferably, the first frame body is fixedly provided with respect to the building opening, the engagement grooves extend to the visible surfaces of a pair of vertical frames and a pair of horizontal frames in the first frame body, the holding frames extend to the four sides of the screen in the screen device, a rotating shaft extending in the vertical direction is provided in the building opening, and either the left or right end of the second frame body is supported on the rotating shaft so as to be freely rotatable. [Effects of the Invention]

[0016] Thus, according to the present invention, in a screen device, the retaining frame fixed to the peripheral portion of the screen is formed by integrally arranging a connecting portion fixed to the peripheral portion and an engaging retaining portion having the engaging protrusion and the sealing portion, so that the screen can be more easily stretched under tension on a frame body attached to a building opening, and further, a screen device and its mounting structure can be provided that can reduce the number of parts and keep costs down.

[0018] 1 to 4 show, as one embodiment of the present invention, a sash frame 1 fixedly attached to a building opening E, such as a window or doorway, that connects a room R to an outside room O, and a screen device 2 according to the present invention attached to the sash frame 1. Arranged in this building opening E, in the viewing direction (front-rear direction from the outside O), are the screen device 2 and a glass shoji screen 3 attached to the sash frame 1 with a predetermined gap S between them. The sash frame 1 is formed into a rectangular shape by right and left vertical sash frame portions 1a, 1b and upper and lower horizontal sash frame portions 1c, 1d. Here, the sash frame 1 constitutes a first frame in a broad sense in the present invention.

[0019] The glass shoji screen 3 is formed by a shoji frame (second frame body) 4 formed into a rectangular shape by right and left vertical shoji frame portions 4a, 4b and upper and lower horizontal shoji frame portions 4c, 4d, and windowpanes 5, 5 attached by double-fitting inside the shoji frame 4. One of the pair of vertical shoji frame portions 4a, 4b (in this embodiment, the left vertical shoji frame portion 4b) is rotatably connected to one of the pair of vertical sash frame portions 1a, 1b (in this embodiment, the left vertical sash frame portion 1b) by a hinge 6. That is, a rotation shaft extending in the up-down direction is formed by the hinge 6 in one of the vertical sash frame portions (left vertical sash frame portion 1b), and the one of the vertical shoji frame portions of the shoji frame 4 (left vertical shoji frame portion 4b) is rotatably supported on the rotation shaft. The hinge 6 may be provided on any vertical frame of the building opening E, and does not necessarily have to be provided on the sash frame 1 as in this embodiment.

[0020] On the other hand, a handle 7 is attached to the other of the pair of vertical shoji frame parts 4a, 4b (in this embodiment, the right vertical shoji frame part 4a). By doing so, the glass shoji 3 can be opened by holding the handle 7 and rotating it toward the room R as shown by the chain line in Figure 3.

[0021] Specifically, the sash frame 1 is fixed to a position biased toward the outside O on the visible surface (the inner peripheral surface extending along the indoor-outdoor direction) of the building opening E, and a mounting frame portion 10 for mounting the screen unit 2 is provided in a flange-like protrusion facing inward on a position biased toward the outside O on the visible surface of this sash frame 1. The mounting frame portion 10 is formed into a quadrangle by a pair of left and right vertical frame portions 11, 11 and a pair of upper and lower horizontal frame portions 12, 12. Here, the mounting frame portion 10 constitutes a first frame body in the narrow sense of the present invention.

[0022] The glass shoji screen 3 is rotatably supported by the hinge 6 on an interior end surface 8a (visible surface) of the sash frame 1 facing the room R. A seal material 8 is attached to a first seal surface 8b of each of the shoji frame sections 4a-4d, which faces the outside O and faces the interior end surface 8a of each of the sash frame sections 1a-1d, and which moves in contact with and away from the interior end surface 8a as the glass shoji screen 3 is opened or closed. When the glass shoji screen 3 is closed, the gap between the first seal surface 8b of the glass shoji screen 3 and the interior end surface 8a of the sash frame 1 is airtightly sealed. The seal material 8 may also be provided on the interior end surface 8a.

[0023] Each of the vertical frame portions 11 and horizontal frame portions 12 of the mounting frame portion 10 of the sash frame 1 has a second sealing surface 13 on its facing surface facing the room R. The screen device 2 is fixedly attached to the second sealing surface 13, and a screen 20 made of, for example, an insect net is stretched inside the mounting frame portion 10. The mounting frame portion (first frame body) 10 and the shoji frame 4 (second frame body) are adjacent to each other in the projection direction, with the mounting frame portion 10 facing the outside O. The facing surface of the shoji frame 4 of the glass shoji 3, i.e., the outside end surface 9, faces the second sealing surface 13 of the mounting frame portion 10 with a predetermined gap S interposed therebetween. As will be described in detail later, the second sealing surface 13 is recessed with an engagement groove 14 for engaging the peripheral edge of the screen 20.

[0024] 5 and 6, the screen unit 2 is formed by a flexible screen 20 having a rectangular outer periphery and a holding frame 21 extending along the peripheral edge of the screen 20, and has a first surface 2a facing the outside O and a second surface 2b facing the opposite side, toward the inside R. The holding frame 21 is formed by vertical holding frames 21a, 21a fixed along a pair of left and right vertical edges of the screen 20, and horizontal holding frames 21b, 21b fixed along a pair of upper and lower horizontal edges, and the holding frame 21 is thereby arranged to surround the entire peripheral edge of the screen 20.

[0025] The holding frame 21, i.e., the pair of vertical holding frames 21a, 21a and the pair of horizontal holding frames 21b, 21b, are formed from a resin material having rubber elasticity, and have a band-shaped connecting portion 22 whose inner portion is fixed along the peripheral edge of the screen 20, and an engaging holding portion 25 connected to the outer end of the connecting portion 22. The connecting portion 22 has a flat fixing portion 23 fixed to the peripheral edge of the screen 20, and a tension generating portion 24 connected to the outer end of the fixing portion 23 for applying elastic tension to the screen 20 stretched on the mounting frame portion 10.

[0026] The tension generating portion 24 is bent toward the second surface 2b and connected to the fixed portion 23, and extends outward at a constant inclination. The engaging and holding portion 25 is connected to the outer end of the tension generating portion 24. Note that the tension generating portion 24 does not necessarily have to be inclined at a constant inclination relative to the fixed portion 23, and may be curved so as to be convex toward the second surface 2b, for example.

[0027] The engagement holding portion 25 has a flat base plate portion 26 connected to the outer end of the tension generating portion 24 so as to be parallel to the fixing portion 23, an engagement protrusion 27 erected on the first surface 2a side of the base plate portion 26, and a seal portion 28 formed on the second surface 2b side of the base plate portion 26. As shown in Figures 2 and 4, the engagement protrusion 27 is engaged with an engagement groove 14 recessed in the second seal surface 13 of the mounting frame portion 10. When the glass shoji screen 3 is closed, the seal portion 28 is disposed in the gap S and abuts against the exterior end surface 9 of the shoji frame 4, and the base plate portion 26 abuts against the second seal surface 13 so as to close the opening of the engagement groove 14, thereby airtightly sealing between the exterior end surface 9 of the shoji frame 4 and the second seal surface 13 of the mounting frame portion 10.

[0028] More specifically, the engaging protrusion 27 has a column portion 27a whose base end is connected to the second surface 2b of the base plate portion 26 and which gradually narrows toward its tip, and an engaging portion 27b connected to the tip of the column portion 27a. The engaging portion 27b is formed by a pair of flange portions 27c, 27c that protrude inward and outward from the tip of the column portion 27a, and is formed wider than the tip of the column portion 27a. The engaging portion 27b is formed into an umbrella shape that gradually widens from the tip toward the base end by the pair of flange portions 27c, 27c.

[0029] On the other hand, the engagement groove 14 recessed in the second seal surface 13 is formed by an introduction portion 14a extending along the length of the pair of vertical frame portions 11, 11 and the pair of horizontal frame portions 12, 12, and one end of which opens to the second seal surface 13, and a storage portion 14b connected to the introduction portion 14a. In this case, the introduction portion 14a is formed wider than the column portion 27a of the engagement protrusion 27 and narrower than the engagement portion 27b, and the other end of which opens to the storage portion 14b. The storage portion 14b is also formed wider than the introduction portion 14a and the engagement portion 27b.

[0030] The pair of flanges 27c, 27c of the engaging portion 27b are engaged around the opening of the introduction portion 14a in the accommodation portion 14b in a non-detachable state, whereby the holding frame 21 is locked to the second seal surface 13 of the mounting frame portion 10, and as a result, the screen unit 2 is attached to the mounting frame portion 10 with the screen 20 stretched. At this time, the pillar portion 27a of the engaging protrusion 27 is housed in the introduction portion 14a of the engaging groove 14. Note that, when attaching the screen unit 2 to the mounting frame portion 10, the engaging portion 27b of the engaging protrusion 27 is formed by the umbrella-shaped flange 27c, so that the engaging protrusion 27 can be easily inserted into the engaging groove 14 and engaged therewith.

[0031] 7(a)-(c) show a mechanism by which the tension generating unit 24 of the holding frame 21 applies elastic tension to the screen 20 of the screen unit 2 mounted on the mounting frame 10. (a) shows a state close to the original state (initial state under no load) of the tension generating unit 24. As the state progresses from (a) to (c), the interior angles θ1 and θ2 formed between the fixing unit 23 and the base unit 26 and the tension generating unit 24 gradually increase, and the elastic tension acting on the screen 20 also increases. For example, when the state shown in (b) is taken as a reference, expansion and contraction of the screen 20 due to temperature or aging, or manufacturing errors, can be absorbed by the tension generating unit 24, and the screen 20 can be maintained in a taut state with respect to the mounting frame 10. It is desirable that both of the interior angles θ1 and θ2 change within a range of 90 degrees or greater.

[0032] The seal portion 28 of the engaging and holding portion 25 has a spring portion 29 that protrudes with its base end connected to the second surface 2b of the base portion 26, and a seal member 30 connected to the tip of the spring portion 29. The spring portion 29 is formed by folding a strip-shaped material from the base end toward the tip end alternately inward and outward in cross section. The seal member 30 extends along the peripheral edge of the screen 20 to which the holding frame 21 is fixed, and is disposed so as to surround the entire outer periphery of the screen 20. The seal member 30 is formed in a strip-like shape that protrudes in the direction in which the spring portion 29 protrudes, i.e., toward the room R and the shoji frame 4.

[0033] Furthermore, a portion of the sealing member 30 that is inward from the connecting portion with the tip of the spring portion 29 (in this embodiment, the inner end of the sealing member 30) is connected to the inner portion of the base plate portion 26 by a connecting piece 31. Meanwhile, an outer end of the sealing member 30 that is outward from the connecting portion with the tip of the spring portion 29 is formed as a free end. When the glass shoji 3 is closed, the surface of the sealing member 30 that faces the shoji frame 4 (in this embodiment, the surface that faces the room R) is in contact with the exterior end surface 9 of the shoji frame 4 with the biasing force caused by the compression of the spring portion 29, as shown in FIGS. 2 and 4 . As a result, the gap S formed between the shoji frame 4 and the exterior end surface 9 is airtightly sealed by the base plate portion 26 that is in contact with the second sealing surface (i.e., the facing surface) 13 of the mounting frame portion 10 and the sealing portion 28 that is in contact with the exterior end surface 9.

[0034] Furthermore, when the screen unit 2 is attached to the mounting frame portion 10, the sealing member 28 can be grasped from the free end side and pulled in a direction to remove the engagement protrusion 27 of the engagement holding portion 25 from the engagement groove 14 of the mounting frame portion 10, thereby releasing the engagement between the engagement protrusion 27 and the engagement groove 14 and allowing the screen unit 2 to be removed from the mounting frame portion 10.

[0035] As described above, according to the present embodiment, in the screen unit 2, the holding frames 21 (i.e., the pair of vertical holding frames 21a, 21a and the pair of horizontal holding frames 21b, 21b) fixed to the peripheral portion of the screen 20 are formed by integrally providing the connecting portions 22 fixed to the peripheral portion of the screen 20 and the engaging holding portions 25 having the engaging protrusions 27 and the sealing portions 28. This makes it easier to tension the screen 20 to the mounting frame portion 10 of the sash frame 1 attached to the building opening E, and also reduces the number of parts and reduces costs. Furthermore, by providing the tension generating portions 24 to the holding frames 21, manufacturing errors and thermal expansion and contraction of the screen 20 can be absorbed by the tension generating portions 24, making it possible to maintain the tensioned state of the screen 20.

[0036] Although one embodiment of the present invention has been described in detail above, the present invention is not limited thereto. The sealing portion 28 may be formed of a material that is not airtight but prevents small animals such as insects from entering through the gap S from the outside O, such as mohair, and does not necessarily have to be airtight. Furthermore, the mounting frame 10 as the first frame and the shoji frame 4 as the second frame may be relatively movable in the left-right direction perpendicular to the front-to-back projection direction (indoor-outdoor direction). Furthermore, the holding frame 21 having the structure of this embodiment does not need to be disposed around the periphery of all four sides of the screen 20; it may be disposed around the periphery of some sides depending on the structure of the frame and screen to which it is attached.
