[Technical field to which the invention belongs]

 This invention is intended, for example, in a general residential house such as a condominium or a detached house, so that a blindfold plate that cannot see through the inside from outside can be attached from the indoor side to a screen door having a net frame attached to a door frame. Related to a blindfold device.

[0002]

[Prior art]

 Conventionally, as a blindfolding device for this type of screen door, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 54-119249, a screen door having a screen surface attached to a door frame has a left and right side. There is a configuration in which a plurality of strip-shaped opaque bodies are inserted between the vertical stiles so as to be vertically stacked so as to cover the entire mesh surface.

Further, as disclosed in Japanese Utility Model Laid-Open Publication No. 56-148500, a groove frame portion having a substantially inverted F-shaped cross section is continuously provided on the inner peripheral portion of a door frame having a net body stretched on the outer surface. An end of a blind body is interposed on the inner side of the groove frame portion, and a blind edge holder with a receiving edge is attached to the outer surface of the end of the blind body so as to be fitted into the groove frame portion, and the door frame is blinded. Some are designed to hold the body.

In addition, a plurality of strip-shaped opaque bodies are simply inserted between the left and right vertical stiles so as to be stacked in the vertical direction, and there is no support for the opaque body on the mesh side. Because of this, the opaque body itself comes into direct contact with the mesh surface, which may be deformed or damaged. Further, when the opaque body itself has an opening with a hood, the hood itself generally protrudes laterally from the upper edge of the opening and curves downward to protrude toward the net surface. Since the depth length is generally large, there is a problem that the hood of the opaque body directly hits the net surface in a small space between the opaque body and the screen door.

On the other hand, in the blind screen door disclosed in Japanese Utility Model Laid-Open Publication No. 56-148500, a groove frame portion having a substantially inverted F-shaped cross section is continuously connected to the inner peripheral edge of the door frame, or the end of the blind body is closed. The structure, such as attaching a blind edge holder with a receiving edge to the outer surface, is very complicated, which makes the screen expensive.In addition, such a blind body is not used for commonly used screen doors. There was a problem that versatility to screen doors was poor, for example, it was impossible to provide a structure for attachment.

In view of the above, the present invention has been devised in view of the above-described circumstances, and is a non-transparent body provided with an opening with a hood in a screen door having a screen surface attached to a door frame. Its simple deformation configuration protects privacy while allowing ventilation, ventilation, lighting, etc., as well as the conventional installation of a blind frame for attaching a blind body, and Easy adjustment between commonly used screen doors between the left and right vertical frames on the indoor side of the door frame, without the need for complicated structures such as attachment. A blindfolding device that can be attached to a blindfold plate that cannot be seen through, and that the hood of the opaque body can be securely held on the door frame without directly hitting the net surface as in the past. The purpose is to provide.

They are firmly fixed without rattling.

When the vertical frame on the indoor side of the door frame is wide, only the holding frame 3 may be used without using the spacer frame 4. Further, when the vertical frame on the indoor side of the door frame is wider than the width of the U-shaped frame of the vertical frame side holding arm 31, the spacer frame 4 is fitted to the vertical frame side holding arm 31. The back side of the U-shaped frame of the joint side surface portion 41 may be fitted to the outside and fixed to the vertical frame by the double-sided adhesive tape material 5 adhered to the back side of the U-shaped frame or the applied adhesive. That is, by attaching the double-sided adhesive tape material 5 to the back of the spacer frame portion 4, when the width of the protrusion of the vertical frame of the door frame is large, the holding frame portion 3 having a large inner width is similarly used. When the width of the projecting portion of the vertical frame of the door frame is small, the spacer frame portion 4 fitted with the holding frame portion 3 with the double-sided adhesive tape material 5 interposed therebetween so as to reduce the width of the inner frame is further reduced. When there is no protrusion in the vertical frame, it can be mounted in each mode by the double-sided adhesive tape material 5 on the back surface of the spacer frame portion 4 fitted in the holding frame portion 3 in the opposite direction. The type can be selected and installed.

Although not shown in the drawings, as another example of the holding frame 3, a strip-shaped mounting base having a horizontally elongated guide hole formed in the center, and one side end of the mounting base are provided. It is formed from a substantially U-shaped holding arm portion which is integrally formed as a fork and bites the inner peripheral edge of the vertical frame, and the total of the upper and lower portions of the blindfold plate 1 at, for example, the left and right edge portions. A screw hole is formed in four places, a slot for guiding the mounting base is applied to the screw hole, a screw body is inserted into the screw hole, and then the screw is screwed into the screw hole. You may make it attach.

As shown in FIG. 6, a plurality of folded plate surface portions 2 can be vertically connected by matching an appropriate number of openings 24 of the folded plate surface portion 2 and a suitable number of hood portions 25 with each other. By expanding the entire size of the plate 1 for use, it can be adjusted corresponding to the size of the vertical width of the door frame. Further, a holding member 51 formed in the shape of a two-folded fold plate for connecting the substantially edge portions of the plurality of fold plate surface portions 2 is provided. That is, as shown in FIG. 8 (a), the holding member 51 bends the band plate into a substantially U-shape via the folded portion 52, and also folds one end of the band plate through the bent portion 53 into a substantially rectangular shape. It is formed. Then, as shown in FIGS. 7 and 9, the plurality of first inclined surface portions 22 and the plurality of second inclined surface portions 23 of the plurality of folding plate surface portions 2 are joined to make the openings 24 and the hood portions 25 coincide with each other. After that, the holding member 51 is inserted from the edge side of the matched first inclined surface portion 22 to the hood portion 25 to bite the first inclined surface portions 22 through the folded portion 52 and to form the bent portion 53. The edges of the plurality of folded plate surface portions 2 can be joined together by being pressed against the folded portions 21 of the folded plate surface portion 2.

Note that the holding member 51 is used in reverse, and the holding member 51 is inserted from the front end of the matched hood portion 25 to the first inclined surface portion 22 so as to bite the hood portions 25 via the folded portion 52. Further, the bent portion 53 may be pressed against and held by the folded portion 21 of the folded plate surface portion 2.

As a specific combination for connecting the plurality of folding plate surface portions 2 in the vertical direction, for example, three folding plate surface portions 2 each having 15 folding portions 21 and seven folding portion portions 21 are provided. The folded plate surface portion 2 forms one surface with one sheet. For example, when used on both surfaces, the folded plate surface portion 2 having 15 folded portions 21 has a total of six folded portions and the folded portion having seven folded portions 21. The plate surface portion 2 is two in total. At this time, the number of vertical bindings is six on one side and four on the upper and lower sides. For example, if used on both sides, the total becomes 18 including two folds 21 as spares. In addition, the number of laterally bound stitches is three on one side and six on the left and right sides. For example, when used on both sides, the total is eight including two folding portions 21 as spare. The size of the fold plate surface 2 is a large size of 30 mm × 15 + 15 mm = 465 mm in the case of 15 folds 21 and a small size of 30 mm × 7 + 15 mm = 225 mm in the case of 7 folds 21. And size are formed. The size of the folding plate surface portion 2 is 15 mm in the case of the folding portion 21, a large size of 26 mm × 15 + 13 mm = 403 mm, and in the case of the seven folding portions 21, it is 26 mm × 7 + 13 mm = 195 mm. Small size is formed. Thus, for example, the assembly size of the folded plate surface portion 2 becomes 26 mm × 14 × 3 + 195 mm = 1287 mm.

Next, an example of assembling and using the embodiment configured as described above will be described. In order to correspond to the size of the left and right width of the door frame, the right and left sides of the entire blind plate 1 are described. In order to expand the size in the direction, as shown in FIGS. 1 and 5, for example, the two left and right folding plate surface portions 2 are arranged upside down and upside down, and the first inclination The surface portions 22 and the second inclined surface portions 23 are arranged so as to be slidable in the lateral direction with each other in a state of being matched. After adjusting the width of the door frame to the right and left dimensions, the front and rear hood portions 25 are formed in a two-fold band shape from the hood portion 25 to the joint portion of the folding plate surface portion 2. The holding member 61 is fitted. At this time, the hood portions 25 are located on the opposite sides with the matching opening portion 24 as the center, and are arranged so as to face each other in an upside down state, so that the left and right blindfold plate bodies 1 are located inside each other. The hood portions 25 do not interfere with each other even if they slide to the side.

A plurality of holding frames 3 are mounted on the outer edge portions of the left and right folding plate surface portions 2 arranged at an appropriate interval. At this time, the first inclined surface portion 22 and the second inclined surface portion 23 of the folding plate surface portion 2 formed in a mountain shape via the folding portion 21 are inserted into the U-shaped frame of the folding plate surface portion side holding arm portion 32 from the lateral direction. The first inclined surface portion 22 and the second inclined surface portion 23 themselves are pressed and held by being inserted into the engagement engagement portion 33 having a mountain shape. At this time, the outer wall surface of the hood portion 25 is arranged substantially flush with the outer wall surface of the folding plate surface portion side holding arm portion 32, and does not protrude outward from the folding plate surface portion 2. In the U-shaped frame of the vertical frame side holding arm portion 31 of the holding frame portion 3, the vertical frame side fitting side surface portion 41 of the spacer frame portion 4 is fixedly arranged by, for example, a double-sided adhesive tape material 5, adhesive or the like. The vertical frame on the indoor side of the door frame is fitted and bitten into the U-shaped frame of the fitting side surface portion 41 without any gap, so that the vertical frame side holding arm portion 31 is firmly fixed without rattling.

Further, in order to increase the vertical size of the entire blind plate 1 so as to correspond to the size of the vertical width of the door frame, a plurality of folding plate surface portions 2 are vertically connected to each other. In this case, as shown in FIG. 7, an appropriate number of the first inclined surface portions 22 and the second inclined surface portions 23 of the plurality of folding plate surface portions 2 are joined to make the openings 24 and the hood portions 25 coincide with each other. Keep it. Then, a plurality of the first inclined surface portions 22 are engaged with each other by, for example, inserting the holding member 51 formed in the shape of a two-folded folding plate from the left and right edge end sides of the matched first inclined surface portions 22 to bite the first inclined surface portions 22 together. The edges of the folded plate surface 2 are connected to each other. In addition, if necessary, the holding member 51 is turned upside down and fitted from the tip end of the matched hood portion 25 to the first inclined surface portion 22 so that the hood portions 25 are bitten via the folded portion 52 and bent. 53 is pressed and held in the folded portion 21 of the folded plate surface portion 2.

In this way, by mounting the blindfold plate 1 on the screen door, the indoor is concealed, and the privacy is maintained because the indoor cannot be seen through the screen from outside. Moreover, if the glass door is always opened while the blindfold plate 1 is attached to the door frame of the screen door, the indoor hood portion is formed by the plurality of hooded openings P of the blindfold plate 1. While concealed by 25, ventilation inside the room and ventilation with the outside can be easily performed through the opening 24.

[0026]

[Effect of the invention]

 Since the present invention is configured as described above, privacy is improved by a simple deformation configuration of the opaque body itself having the hooded opening P in a screen door having a screen surface attached to a door frame. While protecting, it allows ventilation, ventilation, lighting, etc., and it has complicated features such as the continuous installation of a groove frame for attaching a blind body, and the attachment of a blind edge holder as in the past. A blindfold plate that is easy to adjust between the left and right vertical frames on the indoor side of the door frame and that cannot be seen through by adjusting to the vertical and horizontal size of the door frame, even if it is not used for a commonly used screen door 1 can be attached. Further, unlike the conventional case, the hood portion 25 of the opaque body can be securely held on the door frame without directly hitting the net surface.

That is, the present invention is based on the idea that the first inclined surface portion 22 and the second inclined surface portion 23 are alternately and continuously formed by alternately folding the plurality of folded portions 21 arranged in parallel on the plate piece in the opposite direction. This is because the bellows-shaped folded plate surface portion 2 and the hooded opening portion P that is cut and raised and protruded in either the first inclined surface portion 22 or the second inclined surface portion 23 of the folded plate surface portion 2 are formed. With this, it is possible to easily perform indoor ventilation, ventilation with the outdoors, and lighting of light from the outdoors to the interior while hiding the interior. Moreover, since the hooded opening P itself of the blindfold plate 1 has a simple structure, an inexpensive blindfolding device can be provided.

The opening P with a hood extends from the bent edge formed in the folding portion 21 of the folding plate surface portion 2 in either the first inclined surface portion 22 or the second inclined surface portion 23 to the folding plate surface portion 2 itself. The hood portion 25 is formed by cutting and raising the hood portion so that the hood portion 25 is parallel to the hood portion. The plate 1 can be attached, and the contact of the hood portion 25 with the mesh surface can be prevented.

At both left and right edge portions of the folding plate surface portion 2, there are provided slide detachable holding frame portions 3 mounted on both left and right vertical frames on the indoor side of the door frame. A substantially U-shaped vertical frame-side holding arm 31 for holding the vertical frame on the indoor side of the frame, and a mountain-shaped bent shape for elastically pressing and holding the first inclined surface 22 and the second inclined surface 23. And a substantially U-shaped frame having a substantially U-shaped frame-shaped folding plate surface-side holding arm 32 integrally formed with a plurality of mounting engagement portions 33 of the blindfold plate 1. It can be easily attached to the indoor vertical frame of the door frame. Moreover, the folding plate surface portion 2 can be easily attached to and detached from the holding arm portion 32 of the holding frame portion 3 on the folding plate surface portion side.

The two folded plate portions 2 are arranged upside down and upside down, and the first inclined portions 22 and the second inclined portions 23 are aligned with each other so as to be slidable in the horizontal direction. Since they are joined and arranged, the blindfold plate 1 itself can be installed so as to correspond to the size of the left and right width of the door frame.

The first inclined surface portions 22 and the second inclined surface portions 23 are fitted and arranged from the front end portion or the front end portion of the hood portion 25 at the joint position of the folding plate surface portions 2 to the matched first inclined surface portions 22. Since the two-folded band plate-shaped holding member 61 for fixing the two or the second inclined surface portions 23 to each other by pressing is provided, it is possible to prevent the folded plate surface portions 2 from fluttering at the joining position.

Since the plurality of folding plate surface portions 2 can be connected in the vertical direction by matching an appropriate number of the openings 24 and the number of the hood portions 25 with each other, the blindfold plate 1 itself has a vertical dimension of the door frame. It can be installed by adjusting to the size.

The first inclined surface 22 or the hood 25 is engaged with the edge of the first inclined surface 22 or the front end of the hood 25 so as to hold the first inclined surface 22 or the hood 25 together. Since the holding member 51 in the form of a two-folded folding plate is provided, the edge portions of the plurality of folding plate surface portions 2 can be firmly held and fixed.
