Description

Technical Field

[0001] The present invention relates to a shielding device, and is suitable for application to, for example, a shielding device that can prevent scattering and change transparency.

Background Art

[0002] Conventionally, in shielding devices, as a countermeasure against scattering, there are generally those that use a transparent plate such as acrylic, a ground glass-like plate, or a so-called plastic corrugated cardboard made of polypropylene, etc. for shielding.

[0003] In addition, as a shielding device capable of changing transparency, there are a dimming type roll screen, a perforated type roll screen, etc. Further, there are generally shielding devices (for example, a partition with a design) for improving the design property.

[0004] There are also scenes where a transparent plate that combines scattering prevention and face recognition is required, but as a partition, there are also concerns such as the line of sight of the person facing being a concern. As something that softens the line of sight of the person facing, there is a ground glass-like plate. However, although the ground glass-like plate can satisfy the function of softening the line of sight of the person facing, it results in a monotonous design.

[0005] As a countermeasure, for example, it is conceivable to attach a film or fabric with a design property to the ground glass-like plate. In addition, it is possible to assemble one or two flat glass substrates to two or three wooden pedestals erected in the horizontal direction, and in a shielding tool for preventing droplet scattering that enables adjustment of the partition interval, those with a decorative pattern printed on the surface of the glass substrate and a character label display are known (for example, refer to Patent Document 1).

Patent Document 1

[0007] In the splash-proof shield described in Patent Document 1, while the design can be improved by printing on the surface of the glass substrate, if printing is done on only one side, the designs on both sides will be different. Even if the design is improved, the different designs on both sides may impair visibility and create a feeling of confinement. Furthermore, because the design is printed directly onto the glass substrate, it is not possible to change the design pattern or adjust the brightness.

[0008] Therefore, the present invention has been made in view of the above problems, and one of its objectives is to provide a shielding device that is aesthetically pleasing, dimmable, and prevents scattering. [Means for solving the problem]

[0009] The above objective is achieved by the present invention as described below. Specifically, the shielding device of the present invention comprises two transparent plates arranged on the front and back sides, and a sheet-like member placed between the two transparent plates, having a predetermined transparency and a predetermined design.

[0010] In the present invention, it is preferable that the shielding device comprises a fastener for fixing the sheet-like member in a sandwiched state between the two transparent plates.

[0011] In the present invention, it is preferable that the sheet-like member has a die-cut pattern formed on it.

[0012] In the present invention, the cut-out pattern is preferably a predetermined picture, stripe pattern, or border pattern.

[0013] In the present invention, the fastener is preferably a bolt and nut or screw that fastens together the two transparent plates and the sheet-like member as a single unit.

[0014] In the present invention, the fastener is preferably a fastener that secures the two transparent plates and the sheet-like member while sandwiching them together.

[0015] In the present invention, it is preferable that the two transparent plates have a bag structure for housing the sheet-like member on the surfaces facing each other.

[0016] In the present invention, when the sheet-like member is sandwiched between the two transparent plates, it is preferable that a non-slip sheet, which serves as a fixing device capable of holding the sheet-like member, is provided on the transparent plates or the sheet-like member.

[0017] In the present invention, it is preferable that the sheet-like members are sandwiched between the two transparent plates in a stacked state.

[0018] In the present invention, it is preferable that the sheet-like member comprises a first sheet having a stripe pattern in which transparent and opaque portions are alternately formed, and a second sheet having the stripe pattern and a grippable tab.

[0019] In the present invention, it is preferable that a slip-promoting sheet is placed between the front sheet-like member and the back sheet-like member to improve slippage. [Effects of the Invention]

Embodiments for Carrying Out the Invention

[0022] 〔Outline of Embodiment〕 First, an outline of typical embodiments of the invention disclosed in the present application will be described. In the following description, as an example, reference numerals on the drawings corresponding to the components of the invention are described with parentheses.

[0023] 〔1〕In a shielding device (1, 20, 30) according to a typical embodiment of the present invention, two transparent plates (2, 4) arranged on the front side and the back side, and a sheet-like member (6, 43, 44, 43s, 44s) arranged between the two transparent plates (2, 4), having a predetermined transparency and a predetermined design, are provided.

[0024] [[ID=�8]] [2] The shielding device (1, 20, 30) comprises fasteners (7, 9, 10, 11, 25, 48) that fix a sheet-like member (6, 43, 44, 43s, 44s) sandwiched between two transparent plates (2, 4).

[0025] [3] In the shielding device (1,20,30) described above, the sheet-like members (6,43,44,43s,44s) have cutouts (61,43w,44w,43sw,44sw) formed on them.

[0026] [4] In the shielding device (1, 20, 30) described above, the cutout pattern (61, 43w, 44w, 43sw, 44sw) is a predetermined pattern, stripe pattern, or border pattern.

[0027] [5] In the shielding device (1) described above, the fastener (7) is a bolt (7) and nut or screw that fastens together the two transparent plates (2,4) and the sheet-like member (6).

[0028] [6] In the shielding device (1) described above, the fastener (10) is a fastener (10) that secures the two transparent plates (2,4) and the sheet-like member (6) in a sandwiched state.

[0029] [7] In the shielding device (1) described above, the two transparent plates (2,4) have a bag structure (25) on each of the surfaces facing each other that accommodates a sheet-like member (6).

[0030] [8] In the shielding device (1) described above, when a sheet-like member (43, 44) is sandwiched between two transparent plates (2, 4), a non-slip sheet (48) is provided on the transparent plate (2, 4) or the sheet-like member (6) as a fixing device capable of holding the sheet-like member (43).

[0031] [9] In the shielding device (1) described above, multiple sheet-like members (43, 44, 43s, 44s) are stacked and sandwiched between two transparent plates (2, 4).

[0032]

[10] In the shielding device (1) described above, the sheet-like members (43, 44, 43s, 44s) consist of a first sheet (43, 43s) having a stripe pattern in which transparent portions (43w, 44w, 43sw, 44sw) and opaque portions (43b, 44b, 43sb, 44sb) are alternately formed, and a second sheet (44, 44s) having a stripe pattern and a grippable tab (44t, 44st).

[0033]

[11] In the shielding device (1) described above, a slip-promoting sheet (49) is placed between the front sheet-like member (44) and the back sheet-like member (43) to improve slippage.

[0034] [Embodiment] Hereinafter, embodiments of the present invention will be described in detail, divided into the first to third embodiments, with reference to the drawings.

[0035] [First Embodiment] Figure 1 is a perspective view (A) illustrating the concept of a shielding device according to the first embodiment of the present invention, and plan views (B) and (C) showing variations of the sheet-like member. Figure 2 is a perspective view showing the configuration when a hinge is used as a specific example of a fastener according to the first embodiment of the present invention. Figure 3 is a perspective view (A) and (B) showing the configuration in which an anti-slip sheet is attached to the shielding device according to the first embodiment of the present invention. Figure 4 is a plan view showing the configuration of a fastener that holds a sheet-like member sandwiched between two transparent plates in the first embodiment of the present invention.

[0036] In the following embodiments, "up and down" refers to the vertical direction in relation to gravity, and "horizontal" refers to the horizontal direction perpendicular to the direction of gravity. Also, "front" and "back" refer to the depth direction on the page. However, "horizontal" does not need to be exactly perpendicular to the direction of gravity; it is a concept that includes not only areas that can be considered approximately horizontal, but also inclinations that are at least sufficient to realize the present invention.

[0037] In the shielding device 1 according to the first embodiment, as shown in Figure 1(A), it is composed of one transparent plate 2 positioned on the front side (the side closest to the viewer in the figure), one transparent plate 4 positioned on the rear side (the side furthest from the viewer in the figure) relative to the transparent plate 2, and one sheet-like member 6 positioned between these two transparent plates 2 and 4.

[0038] Transparent plates 2 and 4 are transparent members that have complete transparency across their entire surface area, such as thin sheets of highly transparent acrylic or glass. Here, transparent plates 2 and 4 are intended to be transparent members with complete transparency, but are not limited to these, and the degree of transparency includes levels of transparency similar to frosted glass, and includes a degree of transparency that allows the presence of a person facing them to be recognized.

[0039] Through holes 2h and 4h are provided at the four corners of the transparent plates 2 and 4 for fastening together with the sheet-like member 6. The sheet-like member 6 is, for example, a sheet-like member made of a thin fabric. In other words, because the sheet-like member 6 is made of fabric, it is opaque rather than transparent. However, it is not limited to this, and other opaque sheet-like members such as plastic or film may also be used.

[0040] The surface of the sheet-like member 6 has a pattern 61 formed by through-holes of any shape. As a result, the sheet-like member 6 is given an aesthetic appearance by the pattern 61 and also has partial transparency due to the pattern 61. Here, "opaque" includes cases where it is colored or has a frosted glass-like pattern.

[0041] In addition, the sheet-like member 6 also has through holes 6h at its four corners for fastening together with the two transparent plates 2 and 4. That is, the four through holes 2h and 4h in the transparent plates 2 and 4 and the four through holes 6h in the sheet-like member 6 are formed in corresponding positions.

[0042] The transparent plates 2 and 4 are generally larger than the sheet-like member 6, and are sized such that when the sheet-like member 6 is sandwiched between them, it can be completely covered without protruding from the transparent plates 2 and 4.

[0043] As shown in Figure 1(B), the sheet-like member 6 has cut-out patterns 61 made up of various designs. Here, the cut-out patterns 61 are through-holes that have a shape with an arbitrary design applied to the sheet-like member 6, which is the fabric.

[0044] Therefore, the sheet-like member 6 has a cutout pattern 61, for example, a cutout pattern 61 of a plant design, or a cutout pattern 61 that is created by combining geometric patterns made up of polygons such as triangles, squares, and hexagons, or simple shapes such as circles, ellipses, and straight lines, while applying operations such as translation, inversion, rotation, color change, scaling, and division to them in a continuous sequence and developing the arrangement.

[0045] Furthermore, as shown in Figure 1(C), the sheet-like member 6d may have, for example, a cutout pattern 61 with a stripe design, the sheet-like member 6e may have a cutout pattern 61 with a border design, or the sheet-like member 6f may have a cutout pattern 61 with multiple rectangular holes arranged in a regular pattern. Regarding the various patterns constituting the cutout pattern 61, it is possible to select a variety of placement locations, such as placing them only on the upper part of the sheet-like member 6 or only on the lower part.

[0046] In particular, the cutout pattern 61 should preferably be a design of plants or animals, or a symmetrical figure, that looks natural whether viewed from the front or the back. In this case, the design will be natural for both the user viewing the sheet-like member 6 from the front and the user viewing it from the back.

[0047] With the sheet-like member 6, which has such a cutout pattern 61, sandwiched between the front transparent plate 2 and the back transparent plate 4, the three transparent plates 2, 4 and the sheet-like member 6 are fastened together using bolts 7 and nuts or screws or bolts, etc., through the through holes 2h, 4h, and 6h which are arranged opposite each other, thereby forming a shielding device 1 in which the three transparent plates 2, 4 and the sheet-like member 6 are integrated.

[0048] In the above configuration, the shielding device 1 can block the scattering of droplets from users on the front side and users on the back side by the transparent plate 2 positioned on the front side and the transparent plate 4 positioned on the back side. Therefore, droplets adhere only to the transparent plates 2 and 4, and the sheet-like member 6 can be kept clean.

[0049] Furthermore, in the shielding device 1, a predetermined cutout pattern 61 is formed on a sheet-like member 6 sandwiched between two transparent plates 2 and 4. As a result, the user can sense the presence of the person opposite them through the through-holes in the cutout pattern 61, while not having to worry about the person's gaze. In this case, since the sheet-like member 6 is sandwiched between the two transparent plates 2 and 4, it is possible to prevent the user's droplets from scattering through the through-holes in the cutout pattern 61.

[0050] Furthermore, the shielding device 1 allows users on the front and back sides to appreciate the design through the cutout pattern 61 of the sheet-like member 6, and by replacing the sheet-like member 6, users can enjoy different designs.

[0051] Furthermore, the shielding device 1 can take in ambient light through the cutouts 61 (through holes) of the sheet-like member 6, thus maintaining an appropriate level of brightness. In addition, the amount of ambient light incident on the shielding device 1 can be changed by replacing the current sheet-like member 6 with another sheet-like member 6 that has a different design and size of cutouts 61.

[0052] Since this shielding device 1 does not have a stand, it can be used as a tabletop partition by being installed between two desks. Of course, the shielding device 1 can also be used as a floor-standing partition when supported by a stand (not shown).

[0053] Furthermore, as shown in Figure 2, in the first embodiment, instead of using bolts 7 as fasteners, the shielding device 1 can be configured to fix the rear transparent plate 4 to the two frames 8 and to use hinges 9 as fasteners. In this case, the common feature is that a sheet-like member 6 is sandwiched between the front transparent plate 2 and the rear transparent plate 4.

[0054] However, this shielding device 1 has hinges 9 at two locations on the left and right of the lower end that hold the transparent plates 2 and 4 and the sheet-like member 6 in a state where they can be opened and closed. The hinges 9 may be provided at two locations on the left and right of the upper end of the transparent plates 2 and 4, or at two locations on the left and right.

[0055] In this case, the shielding device 1 allows the transparent plate 2 to be opened towards the front relative to the transparent plate 4 via the hinge 9, making it possible to freely and easily replace the sheet-like members 6 (6a to 6f) (not shown).

[0056] Furthermore, in the shielding device 1, as shown in Figure 3(A), a non-slip sheet 11, which serves as a fixing device consisting of a rectangular frame for maintaining the sheet-like member 6 sandwiched between the two transparent plates 2 and 4, can be attached to the surface of the transparent plates 2 and 4 facing the sheet-like member 6, or as shown in Figure 3(B), to the front and / or back surface of the sheet-like member 6.

[0057] The anti-slip sheet 11 is made of a material that can be held in place by the frictional force generated between it and the sheet-like member 6, and rubber is used as an example. However, it is not limited to this, and any other material such as resin, cloth, or paper may be used as long as the position of the sheet-like member 6 can be held in place without shifting due to the frictional force.

[0058] Furthermore, the anti-slip sheet 11 does not necessarily have to form a frame; it may be attached with just two strips at the top and bottom, or with just two strips at the left and right. It may also be attached in a scattered manner at several predetermined locations.

[0059] Furthermore, as shown in Figure 4, in the shielding device 1, instead of using bolts 7 or hinges 9 as fasteners, U-shaped fasteners 10 are used at the upper left and right ends or in the center, and the three components can be fixed together with the sheet-like member 6 sandwiched between the two transparent plates 2 and 4.

[0060] The U-shaped fastener 10 has a leaf spring structure and maintains the sheet-like member 6 firmly sandwiched between the two transparent plates 2 and 4. The U-shaped fastener 10 may also be provided at the lower left and right ends or the lower center, or at two locations on the left and right. In this case as well, the shielding device 1 can also be used in combination with the anti-slip sheet 11.

[0061] [Second Embodiment] Figure 5 is a perspective view (A) and a plan view (B) showing the configuration of a bag structure provided between two transparent plates in a second embodiment of the present invention.

[0062] In the second embodiment, as shown in Figures 5(A) and (B), the shielding device 20 has a bag structure 25 as a fastener with a predetermined thickness that is U-shaped in plan view and capable of housing and fixing a sheet-like member 6 between two transparent plates 2 and 4.

[0063] Therefore, the shielding device 20 has a bag structure 25 interposed between two transparent plates 2 and 4, and the sheet-like member 6 housed in the bag structure 25 is fixed integrally to the two transparent plates 2 and 4.

[0064] The bag structure 25 has two side wall portions 25s that are positioned opposite each other, and a bottom wall portion 25b that is provided horizontally to connect the lower ends of the two side wall portions 25s. Therefore, in the shielding device 20, the bag structure 25 has a space formed between the two side wall portions 25s, the bottom wall portion 25b, and the transparent plates 2 and 4 in which the sheet-like member 6 can be accommodated. The sheet-like member 6 can be accommodated in this space and held in place by the bottom wall portion 25b without falling downwards.

[0065] The bag structure 25 is made of various materials such as plastic, resin, or cloth, and as shown in Figure 5(B), it has an open space at the top, so the sheet-like member 6 only needs to be inserted from the top and does not need to be held in place. Incidentally, the shielding device 20 can also be used in an upright position using the stand 8 (Figure 2).

[0066] [Third Embodiment] Figure 6 shows a perspective view (A), a partially enlarged view (B), and a plan view (C) illustrating the concept of a shielding device according to a third embodiment of the present invention.

[0067] As shown in Figure 6, in the third embodiment, the shielding device 30 has a frame 41 at its lower end and includes two transparent plates 2, 4 and two sheet-like members 43, 44 that are held in a sandwiched state between the two transparent plates 2, 4.

[0068] In this case, the shielding device 30 has spacers 45 and 46 attached to the upper and lower ends of the two transparent plates 2 and 4, respectively, to form a space that allows two sheet-like members 43 and 44 to be held between the two transparent plates 2 and 4.

[0069] The spacers 45 and 46 are made of rod-shaped members of resin or the like that extend horizontally, and are attached parallel to the upper and lower sides of the opposing surfaces of the transparent plates 2 and 4. In other words, the transparent plates 2 and 4 of the shielding device 40 are integrated via the spacers 45 and 46 and are held in place by being inserted between the arms 41a and 41b of the frame 41.

[0070] The sheet-like members 43 and 44 have a vertical height that allows them to be inserted from both the left and right sides into the space between the upper spacer 45 and the lower spacer 46, and their horizontal length is approximately the same as or slightly shorter than the two transparent plates 2 and 4.

[0071] A non-slip sheet 48 of a predetermined size is attached to one or both of the opposing surfaces of the two transparent plates 2 and 4, serving as a fastener to prevent the sheet-like members 43 and 44 from shifting position.

[0072] The anti-slip sheets 48 are attached to the transparent plates 2 and 4 at positions corresponding to the four corners of the sheet-like member 43. However, this is not the only option; the anti-slip sheets 48 may be attached to any location as long as they do not cause the sheet-like member 43 to shift position.

[0073] In this case, the anti-slip sheet 48 is attached to the transparent plate 4, but the anti-slip sheet 48 may also be attached to the transparent plate 2. Alternatively, the anti-slip sheet 48 may be attached to the sheet-like member 43.

[0074] In this case, the sheet-like members 43 and 44 are made of striped fabric having a vertical stripe pattern, with nearly transparent lace fabric portions 43w and 44w as cutouts and opaque light-blocking fabric portions 43b and 44b arranged alternately. In this case, the back side, or the rear side, is the sheet-like member 43, and the front side, or the front side, is the sheet-like member 44.

[0075] The sheet-like member 43 is arranged alternately from the left end as an opaque light-blocking fabric portion 43b, a nearly transparent lace fabric portion 43w, and so on, with the nearly transparent lace fabric portion 43w positioned at the right end.

[0076] Incidentally, although the lace fabric portion 43w is described as nearly transparent, it is actually a lace fabric, so even though it is nearly transparent, it is not as transparent as glass, but rather transparent enough to recognize the presence of the person facing it. Furthermore, a highly opaque fabric can be used for the light-blocking fabric portion 43b, but it is not limited to this; a medium light-blocking fabric may also be used. In other words, it is sufficient if it is opaque enough that the presence of the person facing it cannot be recognized compared to the lace fabric portion 43w.

[0077] On the other hand, the sheet-like member 44 is arranged alternately from the left end as an opaque light-blocking fabric portion 44b, a nearly transparent lace fabric portion 44w, and so on, with an opaque light-blocking fabric portion 44b also arranged at the right end.

[0078] In other words, the sheet-like member 44 has one less opaque light-blocking fabric portion 44w at its right end compared to the sheet-like member 43. However, the sheet-like member 44 has a tab 44t of a predetermined length attached to the opaque light-blocking fabric portion 44b at its right end, which can be grasped by the user. The horizontal length 44td of the tab 44t is slightly longer than the horizontal length 44bt of the opaque light-blocking fabric portion 44b.

[0079] Therefore, the shielding device 30 is formed by inserting, for example, two sheet-like members 43 and 44 between the two transparent plates 2 and 4 from the right end to the left end. At this time, as shown in Figure 7(A), in the shielding device 30, the tab 44t of the front-side, i.e., near-front, sheet-like member 44 protrudes slightly outward from the right end of the transparent plates 2 and 4.

[0080] In this case, the stripe patterns of the front sheet-like member 44 and the back sheet-like member 43 completely overlap. That is, the opaque light-blocking fabric portion 44b of the sheet-like member 44 completely overlaps the opaque light-blocking fabric portion 43b of the sheet-like member 43, and the nearly transparent lace fabric portion 44w of the sheet-like member 44 completely overlaps the nearly transparent lace fabric portion 43w of the sheet-like member 43. This is the fully open state of the sheet-like members 43 and 44, and is a light-transmitting state in which the amount of incident light from outside is maximized through the nearly transparent lace fabric portions 43w and 44w.

[0081] As shown in Figure 7(B), when a user on the front side grasps the tab 44t of the sheet-like member 44 and pulls it to the right, the sheet-like member 43 on the back side does not move due to the anti-slip sheet 48, and only the sheet-like member 44 on the front side moves to the right.

[0082] As a result, the nearly transparent lace fabric portion 43w of the sheet-like member 43 on the back side and the opaque light-blocking fabric portion 44b of the sheet-like member 44 on the front side begin to overlap. At this point, the sheet-like members 43 and 44 are in an intermediate state between fully open and fully closed, and the amount of incident light can be adjusted by moving the sheet-like member 44, resulting in a semi-transparent state.

[0083] Furthermore, as shown in Figure 7(C), when the user on the front side grasps the tab 44t of the sheet-like member 44 and pulls it further to the right, the nearly transparent lace fabric portion 43w of the sheet-like member 43 on the back side and the opaque light-blocking fabric portion 44b of the sheet-like member 44 on the front side completely overlap.

[0084] In this case, the user will only be able to see the opaque light-blocking fabric portions 43w and 44w of the sheet-like members 43 and 44 through the transparent plates 2 and 4. This is a completely closed state by the sheet-like members 43 and 44, resulting in a light-blocking state with zero incident light, where no external light enters. However, if a medium-light-blocking fabric is used for the light-blocking fabric portions 43w and 44w, a low-transparency state will be achieved where a small amount of light from the outside can be felt.

[0085] Therefore, with the shielding device 30, the degree of overlap of the stripe patterns of the sheet-like members 43 and 44 can be adjusted according to the user's wishes by pulling the tab 44t, so that the light can be adjusted while considering the degree to which the presence of the person opposite is noticeable and the amount of incident light.

[0086] In the description of the shielding device 30, we have used sheet-like members 43 and 44 with vertical stripes. However, the present invention is not limited to this, and as shown in Figure 8, sheet-like members 43s and 44s arranged alternately with light-blocking fabric portions 43sb and 44sb with horizontal stripes, and lace fabric portions 43sw, 44sw, etc. as cutouts. In this case, the light can be adjusted by moving the front sheet-like member 44s vertically using the tab 44st.

[0087] Furthermore, although the shielding device 30 was described in the case where the sheet-like members 43 and 44 are arranged to directly overlap, the present invention is not limited to this, and as shown in Figure 9, a transparent sliding-promoting sheet 49 may be placed between the back-side sheet-like member 43 and the front-side sheet-like member 44 to improve sliding. This allows the front-side sheet-like member 44 to slide smoothly when the tab 44t is pulled in the shielding device 30.

[0088] [Other embodiments of the present invention] In the first to third embodiments described above, we have described cases in which one sheet-like member 6 or two sheet-like members 43, 44 are placed between two transparent plates 2, 4. However, the present invention is not limited to these cases, and any structure in which a sheet-like member is sandwiched between transparent plates may be used, and the number of transparent plates and sheet-like members is not limited.
