Description

 Foldable board

 Technical field

 [0001] The present invention relates to a foldable cold protection board.

 Background art

 [0002] A window in a residence is one of indoor and outdoor heat transfer paths. For example, in winter, air that has been cooled in the window glass or in the vicinity thereof, or outdoor that enters through a gap between the window glass and the sash There was a problem that the interior of the room was cold due to the cold air (steamed air) and the heating effect was reduced. For this reason, conventionally, a stagnant space for cold air is formed between the window and these curtains using curtains and shoji screens to improve heating efficiency.

 [0003] However, in the case of a Western-style room, the force that mainly uses curtains has a gap between the peripheral edge of the curtain and the inner wall surface or floor surface of the building and immediately and efficiently reduces the heating effect. It could not be suppressed. In addition, closing the shoji and curtains in the daytime causes problems such as reducing the amount of light collected by the outdoor force, making the room dim, and blocking outdoor scenery, whether in Japanese or Western style. Conventionally, there is one in which a cold protection plate is attached to a window (see, for example, Patent Document 1). However, in the thing of this patent document 1, it is necessary to attach a cold protection board to a window, and it is inferior to wearing property, and an outdoor landscape is obstructed.

 Therefore, as shown in FIG. 15 (A), a shielding plate 2 for shielding cool air is installed near the window on the floor surface 4, and the shielding plate 2 connects the window 1 and the shielding plate 2. It may be possible to form a cool air stagnation space 5 between them. Thereby, the intrusion of cold air into the room can be reduced. In this case, the height of the shielding plate 2 should be set to a predetermined position of the window 1 (for example, a height of 50 to about OOcm) in order to eliminate the problem of the amount of light collected from the outdoor landscape. .

 Disclosure of the invention

 Problems to be solved by the invention

[0005] The shield plate 2 is unstable when it is erected, so it needs to lean against the window side. However, especially when the floor 4 is flooring, the grounding part of the shielding plate 2 There is a risk of slipping and falling, and there is a problem of improving stability during use. On the other hand, when the shielding plate 2 is not stood against the window side, it is necessary to bring the both end edges into contact with the wall surface 3 at the window to maintain the standing state. In addition, since there are multiple types of standards for window 1, there is a problem if it is possible to handle windows with different widths.

[0006] Further, considering the storage property when not in use such as a warm season, it is desirable that the shielding plate 2 be configured to be foldable by making cuts 7 alternately on both sides as shown in the figure. However, as described above, even if the cut 7 is made only in the vertical direction so that it can be folded, it is necessary to lean the shielding plate against the window R. However, if it is leaned against the window 1 while being bent at the notch 7, a gap 6 is formed between the shielding plate 2 and the floor surface 4 at the portion bent at the notch 7, as shown in FIG. There is a risk of cold air leaking from the room.

 Means for solving the problem

[0007] The foldable cold protection board of the present invention includes a plate-like seat portion, a plate-like upright portion, a first hinge portion connected to the seat portion and the upright portion, the seat portion and the upright portion. It has a second hinge that can be folded.

[0008] A plate-like width adjusting portion having a lower end extending below the lower end portion of the upright portion by the thickness of the seat portion may be provided at both ends of the upright portion with a third hinge portion. Oh ,.

[0009] At least one of the slip stoppers may be attached to the back side of the upright part, the bottom side of the seat part, the back side of the width adjustment part, or the bottom part of the width adjustment part.

[0010] In the state of use in which the upright portion and the seat portion are bent at the first hinge portion and the upright portion is raised from the seat portion, the upright portion is bent at the upper portion of the seat portion and receives the lower side of the upright portion. Provide a fall prevention part to prevent the fall.

 [0011] In the usage state, the fall prevention portion may be bent so that the portion facing the upright portion bends the seat portion force upward to receive a position higher than the lowermost portion of the upright portion!

 [0012] The fall prevention unit may be configured to include a joining part that joins the upright part and the fall prevention part so as to be able to come in contact with each other while receiving the upright part.

[0013] It is also possible to provide a configuration that includes a joining portion that joins the seat portion and the fall prevention portion so as to be able to come into contact with each other while the fall prevention portion receives the upright portion. The invention's effect

 [0014] In the folding cold protection board of the present invention, the upright portion is leaned against the window in a state where the seat portion is installed on the floor surface by bending the seat portion and the upright portion via the first hinge portion. A stagnation space for cool air can be formed between the upright portion and the window without creating a gap with the floor surface 4. For this reason, the air cooled by the window and the gap force between the window glass and the sash can be reduced to prevent the outdoor cool air from flowing into the room, and the heating efficiency can be improved. In addition, when not in use, each upright portion can be folded up via the second hinge portion, and can be stored compactly.

 [0015] In addition, the device provided with the width adjusting portion is configured such that the bottom portion is at the same level as the bottom surface of the seat portion when in use, and thus can be installed more stably. Since the width of the folding cold protection board can be changed by adjusting the bending angle of the width adjusting portion with respect to the upright portion, the width of the window can be accommodated.

 [0016] At least one of the back side of the upright part, the bottom side of the seat part, the back side of the width adjustment part, or the bottom part of the width adjustment part is provided with a non-slip part. Even if it is used in a slippery place, it can be prevented from slipping and falling.

 [0017] A device provided with a fall prevention portion can reliably prevent the upright portion from falling to the front side. In addition, the fall prevention part has a structure that has a joint part that allows the upright part and the fall prevention part to be connected to and separated from each other while receiving the upright part. This can be prevented more reliably.

BEST MODE FOR CARRYING OUT THE INVENTION [0020] Hereinafter, a folding cold protection board according to an embodiment of the present invention will be described.

 [0021] As shown in FIGS. 1 (A) and 3 (A), the foldable cold protection board 11 includes a plate-like seat portion 13, a plate-like upright portion 12, and a seat portion 13 and an upright portion 12. And a second hinge portion 15 that allows the seat portion 13 and the upright portion 12 to be folded.

 Specifically, the folding cold protection board 11 is placed near a window on the indoor side, and reduces intrusion of cold into the room. In this embodiment, the foldable cold protection board 11 connects a rectangular flat plate-like upright portion 12 and a rectangular flat plate-like seat portion 13 having the same thickness as the upright portion 12 via a first hinge portion 14. ing. Further, the second hinge portion 15 is provided with 15 at a predetermined interval alternately in the direction different from the first hinge portion 14 (for example, the orthogonal direction), and alternately on the front and back surfaces of the upright portion 12 and the seat portion 13. Here, the window in this case is a discharge window in which the lowermost part of the window opens to the position of the floor surface. As shown in FIG. 8, this window is composed of a window frame la and a glass plate lb fitted to the window frame la.

 [0023] Further, the folding cold protection board 11 can be composed of a synthetic resin board 17 (for example, a heat insulating board such as foamed polyethylene) as shown in FIG. 2A or a wooden board 18 as shown in FIG. 2B. . In the former case, for example, as shown in FIG. 5A, the synthetic resin plate 17 is covered with a synthetic resin woven fabric or sheet 19, and the first hinge portion 14 and the second hinge portion 15 are formed by cutting. . As other forms of the hinge portion 20, a so-called plastic hinge using the flexibility of the seat 19 shown in FIG. 2 (A) and a known hinge such as a hinge shown in FIG. 2 (B) are adopted. be able to. In FIG. 2B, a hinge is fitted into a notch 21 formed at the edge of the upright portion 12 or the seat portion 13 and fixed with a screw 22. This prevents bulkiness during storage.

 [0024] Further, the front and back surfaces of the upright portion 12 or the seat portion 13 are not necessarily flat, for example, by forming an arbitrary concave shape from the parting line P as shown in FIG. A predetermined decoration (for example, picture, character, character, etc.) may be applied. As a result, the design as an interior can be improved. In the folding cold protection board 11 shown in FIGS. 2A, 2B, and 2C, the upright portion 12 and the seat portion 13 have the same structure.

[0025] And, in this foldable cold protection board 11, as shown by the lattice pattern in Fig. 1 (B), the upright portion 1 Anti-slip portions 16 are attached to the back side of 2 and the bottom side of the seat portion 13. Such a non-slip portion 16 may be attached to either the back side of the upright portion 12 or the bottom surface side of the seat portion 13.

 [0026] The anti-slip portion 16 can be formed of a sheet-like material such as a double-sided tape, a rubber sheet (including a surface processed into a predetermined shape), and a hook-and-loop fastener. That is, the non-slip portion 16 may be appropriately changed according to the material of the contact object (such as the wall surface 3 and the floor surface 4) of the upright portion 12 and the seat portion 13, for example, in the case of flooring, a double-sided tape or a rubber sheet. For carpets, hook-and-loop fasteners should be used. When double-sided tape is used, it is recommended to use one that can be repeatedly peeled at least on one side, and protect the adhesive surface with a release sheet (not shown) when not in use. In addition, the non-slip portion 16 does not need to be made of the same material for the upright portion 12 and the seat portion 13, for example, a double-sided tape is used for the upright portion 12 and a rubber sheet is used for the seat portion 13. You may make it. Further, the mounting position of the anti-slip portion 16 need not be limited to the illustrated one, and can be changed as appropriate.

 The foldable cold protection board 11 configured as described above is installed as shown in FIG. That is, the seat 13 is bent so as to be substantially orthogonal to the upright portion 12 and placed on the indoor window. As a result, a stagnant space 5 is formed between the window 1 and the upright portion 12. In this case, the upright portion 12 stands up to the center position in the vertical direction of the window or the vicinity thereof.

 [0028] As described above, the folding cold protection board 11 is formed with the stagnant space 5 between the window 1 and the upright portion 12, so that the air cooled by the window 1, the window glass, and the sash It is possible to reduce the cool air outside the room from flowing into the room through the gap and improve the heating efficiency. Further, the upright portion 12 and the seat portion 13 can be prevented from being bent at the second hinge portion 15 by being bent through the first hinge portion 14. Thereby, stability can be improved. Further, it becomes possible to bring the both end edges of the upright portion 12 and the entire seating surface of the seat portion 13 into contact with the wall surface 3 and the floor surface 4 on the indoor side, so that the upright portion 12 can be maintained in a stable state and the stagnant space 5 Can be reliably formed.

 [0029] Further, when not in use, the folding cold protection board 11 can be folded into a state where the upright portions are overlapped via the second hinge portion 15 as shown in FIG. ing.

[0030] Note that the upright portion 12 and the seat portion 13 may have a shape other than a rectangular shape. The upper side and the lower side of the seat portion 13 may be arbitrarily curved, and the shape when the upright portion 12 and the seat portion 13 are developed on a plane may be circular, trapezoidal, or polygonal. In addition, the size and the like of each of the upright portions 12 and the corresponding seat portions 13 can be changed according to the parts to be placed.

 [0031] Next, a folding cold protection board according to another embodiment will be described. As shown in FIGS. 5 (A) and 5 (B), the folding cold protection board 11 has a lower end at the both ends of the upright portion 12 that is lower than the lower end portion of the upright portion 12 by the thickness of the seat portion 13. An extended plate-like width adjusting portion 23 is continuously provided by a third hinge portion 24. Further, in this embodiment, the width adjusting part 23 is provided at both ends of the upright part 12, and the suction cup 50 that can be adsorbed on the indoor side of the window 1 is employed as a non-slip part of the upright part 12. The members or portions that are mainly different from the above embodiment and have the same action as the above embodiment are denoted by the same reference numerals.

 Specifically, in this embodiment, the width adjusting portion 23 is connected to both ends of the upright portion 12 so as to be swingable via the third hinge portion 24. The width adjusting portion 23 has a bottom portion 23a that is lower than the lower end portion of the upright portion 12 by the thickness of the seat portion 13 so that the bottom portion 23a is at the same level as the bottom surface of the seat portion 13 in use. It is a rectangular flat plate that extends. Further, in this embodiment, the upper portion of the width adjusting portion 23 is set to the same height as the upper portion of the upright portion 12. In this embodiment, the third hinge portion 24 is formed in parallel with the second hinge portion 15, and the width adjusting portion 23 can be folded in the same manner as the upright portion 12 and the seat portion 13.

 [0033] Further, the width adjusting portion 23 may be provided with a non-slip portion such as a rubber sheet on the bottom portion 23a. The width adjusting portion 23 may be a flat plate whose lower end extends downward from the lower end portion of the upright portion 12 by the thickness of the seat portion 13 .For example, the upper portion is at the same level as the upright portion 12. It does not have to be.

 FIG. 6 is a cross-sectional view taken along the line BB in FIG. 5 (B). The suction cup 50 serving as the anti-slip portion 16 includes a suction portion 50a and a shaft portion 50b extending from the non-suction surface. It is composed of a flexible thin plate-like locking portion 50c. The locking part 50c is a disk having a slightly larger diameter than the shaft part 50b. A mounting hole 25 having substantially the same diameter as the shaft portion 50b is formed in the upright portion 12, and the shaft portion 50b is screwed into the mounting hole 25 from the side of the locking portion 50c.

Further, the suction cup 50 as the anti-slip portion 16 has the locking portion 50c on the front side as shown in FIGS. 7 (A) and 7 (B). You may comprise so that it may not expose. In this case, the suction cup 50 uses a spherical locking portion 50c having a diameter larger than that of the shaft portion 50b provided at the tip of the shaft portion 50b. Further, a storage fitting portion 28 for the suction cup 50 is formed on the back surface side of the upright portion 12, and a mounting hole 25 is provided on the bottom of the storage fitting portion 28. A pair of insertion members 26, 27 in the form of a half-pipe with the shaft portion 50b and the locking portion 50c sandwiched in the mounting hole 25 are fitted. The insertion members 26 and 27 may be joined to the mounting hole 25 by appropriate means such as screwing or bonding.

[0036] The foldable cold protection board 11 according to another embodiment is configured such that the width dimension of the foldable cold protection board 11 can be adjusted by adjusting the bending angle of the width adjusting portion 23 with respect to the upright portion 12. ing.

 [0037] FIGS. 8 (A) and 8 (B) are cross-sectional views taken along line AA in FIG. 5 (B) when the folding cold protection board 11 is used. In this second embodiment, the width adjustment for the upright portion 12 is performed. By adjusting the bending angle of the section 23, the width dimension of the folding cold protection board 11 can be changed. For this reason, it can respond to the width dimension of the window 1. That is, as shown in FIGS. 8 (A) and 8 (B), when the window 1 is a bay window type or when the window 1 is provided over substantially the entire width of one wall surface in the room, the illustration is omitted. Corresponds to the width dimension of the window 1 and the width dimension of the installation place of the folding cold protection board 11 is different. Therefore, in the folding cold protection board 11 of the second embodiment, the folding cold protection board 11 is adjusted to the width dimension of the installation location by adjusting the bending angle of the width adjusting portion 23 provided at both ends of the upright portion 12. It can be easily handled. The folding cold protection board 11 itself may be configured to be extendable in the width direction in accordance with the width of the window.

 [0038] In the folding cold protection board 11 of another embodiment, the suction cup 50 is used as an anti-slip portion as shown in FIGS. This has the advantage that the upright portion 12 can be stabilized more easily and reliably.

[0039] The suction cup may be provided with a clip (not shown) instead of the locking portion 50c of the suction cup 50 and attached to the upper edge of the upright portion 12 with the clip. Further, the suction cup may be one in which the back surface of the suction portion 50a is adhered to the back side of the upright portion 12 with a double-sided tape or the like, or the base portion of the shaft portion 50b is pivotally attached to the upright portion 12. When the shaft portion 50b is pivotably attached, the storage fitting portion (not shown) having a cross-sectional shape including the shaft center of the suction portion 50a and the shaft portion 50b is engraved on the back side of the upright portion 12. Well ... As described above, the embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, as shown in FIG. 1 A sliding member 29 for limiting the bending angle of the hinge portion 14 from 90 degrees to 180 degrees may be attached to at least one side surface portion 30 of the folding cold protection board 11. In addition, as shown in FIG. 9B, a plurality of foldable cold protection boards 11 and 11 may be arranged in a horizontal row and connected via a connection structure 31. As the connection structure 31, as shown in the figure, a ridge 33 whose tip is enlarged in diameter is slidably fitted into the guide groove 34, or a clip (not shown) is integrated with one side surface 30 of the folding cold protection board 11. What was formed can be considered. As shown in FIG. 9 (C), instead of the connection structure 31, a connection tool 32 (eg, a clip) may be used. As the coupling tool 32, for example, an H-shaped clip 32 having substantially the same length as the coupling portion of the upright portion 12 and the seat portion 13 may be used so that no gap is generated at the coupling portion of the folding cold protection boards 11 and 11. ! /

 [0041] Next, another embodiment of the folding cold protection board will be described.

 [0042] As shown in FIGS. 10 and 13, this folding-type cold protection board is constructed such that the upright portion 12 and the seat portion 13 are bent at the first hinge portion 14, and the upright portion 12 is raised with respect to the seat portion 13. In the state of use, it is provided with a fall prevention part 40 that is bent to the upper part of the seat part 13 and receives the lower side of the upright part 12 to prevent the upright part 12 from falling down.

 [0043] Specifically, as shown in FIGS. 10 and 11, the foldable cold protection board 11 falls over the lower end portion of the foldable cold protection board 11 of the first embodiment via the fourth hinge portion 35. The prevention part 40 is connected. In addition, a fifth hinge portion 36 is provided on the fall prevention portion 40 on an extension line of the second hinge portion 15.

 In this embodiment, as shown in FIG. 13, the seat portion 13 and the fall prevention portion 40 are folded and used.

 That is, from the state shown in FIG. 11, the seat portion 13 is first bent so as to be substantially orthogonal to the upright portion 12 via the first hinge portion 14 as shown in FIG. Next, as shown in FIG. 13, the fall prevention portion 40 is bent to the upper side of the seat portion 13 through the fourth hinge portion 35.

[0045] The foldable cold protection board 11 can be installed near the indoor window as shown in FIG. When installed in this way, the fall prevention part 40 faces the upright part 12, and when the upright part 12 tries to fall down indoors, it receives the lower side of the surface of the upright part 12 and prevents the upright part 12 from falling down. Can. For this reason, the upright portion 12 is brought close to the window and leaned on the window substantially vertically. Can be effectively prevented from falling to the indoor side.

 [0046] Even in the state of Fig. 13, the fall prevention unit 40 receives the lower side of the surface of the upright part 12 and has a function of preventing the upright part 12 from falling down. In this state, the portion 40a facing the upright portion 12 may be provided in a swingable manner via the sixth hinge portion 39. That is, as indicated by the phantom line, a sixth hinge part 39 parallel to the fourth hinge part 35 is provided. The state force shown in FIG. 13 can also be brought into the state shown in FIG. 14 by swinging the portion 40a facing the upright part 12 through the sixth hinge 39 in the operating state by 90 ° upward. Even in the state of FIG. 14, the lower side of the surface of the upright portion 12 can be supported, and the upright portion 12 can be prevented from falling to the surface side. In particular, in the state of FIG. 14, the fall prevention part 40a is higher than in the state of FIG.

 [0047] At this time, the upright portion 12 and the fall-preventing portion 40 (40a are prevented so that the portion 40a facing the upright portion 12 does not swing forward through the sixth hinge portion 39 in the use state. ) May be joined via the joint 41. For example, the joining portion 41 can be configured to join the upright portion 12 and the fall prevention portion 40 (40a) with a hook-and-loop fastener or a magnet. As described above, the upright portion 12 and the fall prevention portion 40 (40a) are joined to each other via the joining member so as to be able to come into contact with and away from each other, so that the upright portion 12 can be further prevented from falling.

[0048] In addition, in a state in which the fall prevention unit 40 receives the upright part 12, the seat part 13 and the fall prevention part 40 can be brought into and out of contact with each other via a joint 41A (see FIGS. 12B and 12C). You may make it join. In this case, as the joint 41A, a surface fastener magnet or the like can be used as in the joint 41A. That is, as shown in FIGS. 12 (B) and 12 (C), the joining portion 41A includes a pair of flat plate bodies 51 and 52, and one flat plate body 51 is attached to the surface 53 of the seat portion 13, and The other flat plate 52 is attached to the seat-corresponding surface 54 of the fall prevention unit 40. Then, as shown in FIG. 13, the first flat plate body 51 and the second flat plate body 52 face each other in a state where the fall prevention portion 40 is superimposed on the seat portion 13, and these are joined together. Then, the fall prevention part 40 is joined on the seat part 13. When the joint 41A is a hook-and-loop fastener, a tape body (sheet body) in which one of the first flat plate body 51 and the second flat plate body 52 is formed with a fine force and a large number of loops are densely formed. And the other is fine, and a tape body (sheet body) in which a large number of hooks are densely formed, and in the case of a magnet, either the first flat plate body 51 or the second flat plate body 52 is connected to the positive side. And the other is the negative side. Therefore, the joint portion 41A can be separated by pulling the fall prevention portion 40 away from the seat portion 13 from the state where the first flat plate body 51 and the second flat plate body 52 are joined.

 [0049] Further, as the first flat plate body 51 and the second flat plate body 52, even if the first flat plate body 51 and the second flat plate body 52 are discontinuous as shown in FIG. As shown in FIG. 12C, the first flat plate body 51 and the second flat plate body 52 may be continuously arranged. When arranged in this manner, they can be arranged on the entire surface 53 of the seat portion 13 or on the entire seat-corresponding surface 54 of the fall preventing portion 40. In the case of a continuous form, as shown in FIG. 4, if the first flat plate body 51 and the second flat plate body 52 are each composed of one sheet, this foldable cold protection board is used. It is necessary to have flexibility so that it can be folded when folded. In addition, the continuous form includes a plurality of small pieces that are not composed of a single sheet, and adjacent pieces are continuously arranged. At this time, the first flat plate body 51 and the second flat plate body 52 may be flexible if the abutting portions of the adjacent small pieces correspond to the bent portions.

 [0050] Thus, by providing the joint portion 41A, the fall prevention portion 40 can be prevented from being lifted, and the upright portion 12 can be maintained in a stable standing state. In addition, since the fall prevention unit 40 is prevented from being lifted, it is not necessary to increase the longitudinal length L of the seat unit 13 and the fall prevention unit 40 to improve the stability of the fall prevention unit 40. Therefore, the length L in the front-rear direction can be shortened, and material costs can be saved and compactness can be achieved.

 Industrial applicability

 [0051] The window may be other than the sweep window. In addition, even if the fall prevention part 40 (40a) is provided over the entire length in the width direction of the foldable cold protection board 11, an appropriate number of the fall prevention parts 40 (40a) are provided at any position, for example, at both ends in the width direction and at both ends and the width direction intermediate part. Moho.
