Description

TECHNICAL FIELD The present invention relates to a foldable and self-supporting tabletop screen that is installed and used on a tabletop such as a desk, table, counter, stand, etc.

Due to the spread of the new coronavirus, it is necessary to take sanitary measures in environments where many people stay and come into contact with each other. For example, when multiple people have a face-to-face conversation, the risk of infection due to droplets such as saliva increases. For this reason, measures are being taken to prevent the spread of droplets by hanging transparent vinyl sheets from the ceiling and installing transparent acrylic boards on desks and other surfaces. However, these types of vinyl sheets and acrylic boards are basically permanently installed and are inconvenient to carry.

On the other hand, tabletop screens that are foldable for portability and freestanding so that they can be installed on a tabletop such as a desk have been known. This type of tabletop screen is made of, for example, corrugated cardboard, and has a structure in which a plurality of wall portions are connected in the left-right direction with bent portions in between. When in use, the space in front of and to the side of the user on the tabletop can be partitioned off from the surrounding space by expanding the adjacent walls to form a V-shape in plan view and making the tabletop screen independent. When not in use, the tabletop screen can be easily carried by stacking the plurality of walls on top of each other and folding the tabletop screen (for example, see Patent Documents 1 to 3).

Further, the first plate member 2 is bendable relative to the second plate member 3. The first plate-like member 2, the second plate-like member 3, and the third plate-like member 4 are brought into a flat state in which both side parts 21, 31, and 41 are flush with the front parts 20, 30, and 40, and the first plate-like member By folding back the member 2 and stacking it on the surface of the second plate member 3 opposite to the surface on which the third plate member 4 is stacked, the tabletop screen 1 can be used when not in use as shown in FIG. It can be folded to make it compact.

Among the constituent members of the tabletop screen 1, the first plate-like member 2, the second plate-like member 3, and the third plate-like member 4 are composed of one base material 10 shown in FIGS. 4 and 5. Note that the shape of the base material 10 is not limited to the shapes shown in FIGS. 4 and 5. The base material 10 has enough strength and thickness to maintain the shape of the tabletop screen 1 installed on the tabletop, and can be formed using a sheet material made of various known paper materials such as cardboard and cardboard, for example. can. The base material 10 can also be formed using a sheet material or a plate material made of a plastic material such as plastic cardboard, a plastic board, a foamed plastic sheet, etc., and the material of the base material 10 is not particularly limited. In this embodiment, the base material 10, that is, the first plate member 2, the second plate member 3, and the third plate member 4 are made of corrugated cardboard.

In the base material 10 shown in FIGS. 4 and 5, the first plate member 2, the second plate member 3, and the third plate member 4 have a horizontally long rectangular shape, and are connected linearly in this order. It is set up. Although the widths of the first plate member 2 and the second plate member 3 are longer than the width of the third plate member 4, they may be equal. The second plate member 3 and the third plate member 4 have openings 6 and 7 formed in their centers. In this embodiment, the two openings 6 and 7 have a horizontally long substantially rectangular shape and have the same size, and are in a line-symmetrical positional relationship with the fold line L2 as the axis of symmetry. Note that the two openings 6 and 7 do not necessarily have to be substantially rectangular, and may have other shapes as long as the user's face can be seen through the openings 6 and 7. Further, the two openings 6 and 7 do not necessarily have to have the same size and shape, and if they face each other when the second plate-like member 3 and the third plate-like member 4 are overlapped, they will have different sizes and shapes. You can leave it there.

Folds L1 and L2 are provided at the boundary between the first plate member 2 and the second plate member 3, and at the boundary between the second plate member 3 and the third plate member 4. The first plate-like member 2 can be bent toward one side of the second plate-like member 3 along the fold line L1 (can be folded in a valley in FIG. 4), and the third plate-like member 4 can be bent toward one side of the second plate-like member 3 along the fold line L2. It can be folded toward the other side (mountain folding is possible in FIG. 4).

The types of folds L1 and L2 are not particularly limited, but the fold L1 requires that the first plate member 2 be folded over the second plate member 3 when the tabletop screen 1 is not in use (see FIG. 3). In order to suppress the first plate member 2 from returning to its original position and fold the first plate member 2 back, half-cut lines are used instead of normal ruled lines (reverse fold lines). It is preferable. Note that the first plate-like member 2 and the second plate-like member 3 are connected not only at the front parts 20 and 30 but also at the pair of side parts 21 and 31.

The fold line L2 is a fold line formed by the third plate-like member 4 folded over the second plate-like member 3 when the tabletop screen 1 is in use (see FIGS. 1 and 2) and when the tabletop screen 1 is not in use (see FIG. 3). Therefore, in order to neatly fold back the third plate-like member 4, it is preferable to use a plurality of score lines spaced apart from each other at regular intervals rather than regular ruled lines. A normal ruled line may be provided between adjacent score lines. In addition, in the second plate-like member 3 and the third plate-like member 4, the front parts 30 and 40 are joined together at a part without a cut line, but the pair of side parts 31 and 41 are independent from each other. .

The first plate member 2 and the second plate member 3 are provided with a pair of left and right fold lines L3 that are orthogonal to the fold line L1. The pair of folds L3 are located on the left and right sides of the opening 6 of the second plate member 3, and the pair of folds L3 allow the first plate member 2 and the second plate member 3 to , 30, and a pair of side surfaces 21, 31. The opening 6 is arranged in the front part 30 of the second plate member 3. The pair of side parts 21, 31 can be folded (mountain foldable in FIG. 4) with respect to the front parts 20, 30 along a crease L3, and the side faces of the second plate member 3 on which the third plate member 4 is overlapped. (See Figure 6). In the present embodiment, the upper ends of the pair of folds L3 extend to the upper edge of the front part 30 of the second plate-like member 3, but the lower ends extend below the front part 20 of the first plate-like member 2. It does not extend to the side edge and is connected to a cutting line C, which will be described later. The positions of the pair of fold lines L3 and the pair of cutting lines C correspond to the inner edges of the pair of side surfaces 21 and 31 of the first plate member 2 and the second plate member 3.

The third plate member 4 is provided with a pair of left and right fold lines L4 that are perpendicular to the fold line L2. The pair of folds L4 are located on the left and right sides of the opening 7 of the third plate-like member 4, and the pair of folds L4 allow the third plate-like member 4 to have a front part 40 and a pair of side parts 41. It is divided into. The opening 7 is arranged in the front part 40 of the third plate member 4. The pair of side parts 41 can be folded (valley foldable in FIG. 4) with respect to the front part 40 along the fold line L4, and the pair of side parts 21 and 31 of the first plate-like member 2 and the second plate-like member 3 are foldable. The bendable direction means that the base material 10 shown in FIG. 4 can be bent in the opposite direction, and the tabletop screen 1 shown in FIG. 1 can be bent in the same direction. The positions of the pair of folds L4 correspond to the inner edges of the pair of side surfaces 41 of the third plate member 4.

The position of the pair of folds L4 that allows the pair of side surfaces 41 of the third plate member 4 to be bent is such that the pair of side surfaces 21 and 31 of the first plate member 2 and the second plate member 3 can be bent. The position of the pair of fold lines L3 is shifted in the left-right direction. In this embodiment, the position of the pair of folds L4 is such that the width of the front part 40 of the third plate member 4 is shorter than the width of the front parts 20 and 30 of the first plate part 2 and the second plate member 3. is shifted inward from the position of the pair of folds L3, and the pair of side surface portions 41 is displaced inward from the pair of side surface portions 21, 31, so that the width of the third plate member 4 is smaller than that of the first plate. It is shorter than the width of the shaped portion 2 and the second plate-shaped member 3.

The types of the fold line L3 and the fold line L4 are not particularly limited, but when the tabletop screen 1 shown in FIGS. Since the portions 21, 31, and 41 are bent toward the front side, in order to firmly bend the pair of side portions 21, 31, and 41, it is necessary to use the ruled line and the cut line or half-cut line (half-cut line) rather than the normal ruled line. ) are preferably constructed of lead ruled lines alternately placed at approximately equal intervals.

A support portion 22 protrudes from a portion of the inner edge of the pair of side surfaces 21 of the first plate member 2 on the side that contacts the tabletop (the lower side in FIG. 4). The support portion 22 is integrally provided with the side surface portion 21 by cutting the front surface portion 20 inward from the lower end of the fold line L3 to the lower edge of the base material 10. In the base material 10, the cutting line C for forming the support part 22 has a curved shape convex to the front part 20 side, in this embodiment, an arc shape, and the support part 22 has a quarter circle shape. By providing the support portions 22 on the pair of side surfaces 21 of the first plate member 2, in the tabletop screen 1 shown in FIGS. 1 and 2, the pair of side surfaces 21 of the first plate member 2 in contact with the tabletop are Since the front part 20 protrudes not only from the front side but also from the back side, the tabletop screen 1 installed on the table is prevented from easily falling down on either the front side or the back side. Moreover, since the cutting line C has a curved shape convex toward the front part 20 side, when the pair of side parts 21 of the first plate-shaped member 2 are bent with respect to the front part 20, the support part 22 can be It can be smoothly projected to the back side without being significantly interfered with by the front part 20. Note that the shape of the support portion 22 does not necessarily have to be a quadrant, and may be triangular, rectangular, trapezoidal, or the like.

A concave cutout 32 is provided on the outer edge of the pair of side surfaces 31 of the second plate-shaped member 3 . In the tabletop screen 1 shown in FIGS. 1 and 2, the recess 32 connects the side surfaces 31 and 41 of the second plate-like member 3 and the third plate-like member 4 that are bent toward the front and are located in the same direction. It constitutes a connecting means. Although the recess 32 has a vertically long rectangular shape in this embodiment, it may have various shapes such as a horizontally long rectangle, a triangle, a trapezoid, a semicircle, and a vertically long or horizontally long semiellipse.

A protrusion 42 that can be engaged with the recess 32 is provided on the outer edge of the pair of side surfaces 41 of the third plate member 4 . The convex part 42 constitutes the above-mentioned connecting means together with the concave part 32, and is located at the same height as the concave part 32 in the tabletop screen 1 shown in FIGS. 1 and 2. As shown in an enlarged view in FIG. 1, the convex portion 42 is formed by a portion 42A on the side surface portion 41 fitting into the concave portion 32 and a portion 42B on the tip side protruding from the concave portion 32 and being caught on the side surface portion 41. The shape is not particularly limited as long as it engages with 32 and is difficult to slip out of the recess 32. Note that in this embodiment, the convex portion 42 has a vertically long trapezoidal shape that becomes wider toward the tip. A crease L5 such as a ruled line is provided at the boundary between the convex portion 42 and the side surface portion 41. The convex portion 42 can be bent (mountain foldable in FIG. 4) relative to the side surface portion 41 at the fold line L5.

Among the constituent members of the tabletop screen 1, the window member 5 is composed of a single sheet material, film material, plate material, or the like. The material of the window member 5 is not particularly limited as long as it is transparent, that is, the user can see the back side of the tabletop screen 1 through the window member 5. The window member 5 is preferably colorless and transparent, but may be colored and transparent. The shape of the window member 5 is a horizontally long rectangle in the present embodiment, but it may be particularly large as long as it can cover at least the openings 6 and 7 of the second plate member 3 and the third plate member 4. Not limited.

In order to ensure that the window member 5 closes the openings 6 and 7 of the second plate member 3 and the third plate member 4 without being misaligned with respect to the openings 6 and 7 of the second plate member 3 and the third plate member 4, It is preferable to fix it to at least one of the third plate member 3 and the third plate member 4, for example, by pasting using an adhesive or the like. In this embodiment, the window member 5 is attached to the front side surface of the second plate member 3.

Next, a procedure for assembling the tabletop screen 1 shown in FIG. 1 using the base material 10 shown in FIGS. 4 and 5 will be described. First, as shown in FIG. 5, the third plate member 4 is folded toward the front at the fold line L2 and overlapped with the second plate member 3. The third plate member 4 superimposed on the second plate member 3 is attached to the second plate member 3 using, for example, an adhesive to prevent it from separating from the second plate member 3. It is preferable to fix it by.

Then, as shown in FIG. 6, the pair of side surfaces 21, 31, 41 of the first plate member 2, second plate member 3, and third plate member 4 are bent toward the front at fold lines L3, L4. By forming a V-shape with the front parts 20, 30, and 40, the shape can stand on a tabletop.

Finally, as shown in FIG. 7, the pair of protrusions 42 of the third plate member 4 are bent toward the back at the fold line L5 and engaged with the pair of recesses 32 of the second plate member 3. The side surfaces 31 and 41 on the direction sides are connected to each other. As a result, the tabletop screen 1 is assembled.

As described above, according to the tabletop screen 1 of this embodiment, as shown in FIG. 1, the openings 6 and 7 are formed facing the second plate member 3 and the third plate member 4 which are stacked on top of each other. The openings 6 and 7 are closed by a transparent window member 5. Therefore, as shown in Figure 2, when a user has a face-to-face conversation with multiple people, by setting up a tabletop screen 1 in front of the user, the user can prevent the droplets from spreading toward the other person due to the tabletop screen 1. It is possible to have a conversation while checking the other person's face through the openings 6 and 7 while preventing the other party from being exposed to the other person's face.

In addition, according to the tabletop screen 1 of the present embodiment, the second plate-like member 3 and the third plate-like member 4 have a bendable position (fold line L3, L4 position) is shifted in the left-right direction, and the side portions 31 and 41 on the same direction side bent toward the front side of the second plate-like member 3 and the third plate-like member 4 are connected to each other by a connecting means (a recessed portion). 32 and a convex portion 42). As a result, the pair of side surfaces 31 of the second plate-like member 3 and the pair of side surfaces 21 of the first plate-like member 2 connected thereto are prevented from spreading toward the back in an attempt to return to their original state. As a result, the pair of side surfaces 21 of the first plate member 2 in contact with the tabletop are maintained in a V-shape with the front surface 20. Therefore, the tabletop screen 1 can be satisfactorily made to stand on its own during use, and it is possible to prevent the tabletop screen 1 from becoming unable to stand on its own and falling down during use.

In addition, according to the tabletop screen 1 of this embodiment, after use, the engagement between the recess 32 and the projection 42 is released, and all the side surfaces 21, 31, 41 are opened, and the first plate member 2 and the first plate member 2 are separated. After making the second plate-like member 3 and the third plate-like member 4 flat, the first plate-like member 2 is folded back to the back and overlapped with the second plate-like member 3, as shown in FIG. The tabletop screen 1 can be folded into a flat state to make it compact. Therefore, it is possible to save the storage space of the tabletop screen 1 when not in use, and it can be easily carried to, for example, a company conference room or a free space, as needed.

Although one embodiment of the present invention has been described above, the specific aspect of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit thereof.

For example, as a modified example, in the embodiment described above, the recess 32 constituting the connecting means is provided on the side surface 31 of the second plate member 3, and the convex portion 42 is provided on the side surface 41 of the third plate member 4. However, the recessed portion may be provided on the side surface portion 41 of the third plate-like member 4, and the convex portion may be provided on the side surface portion 31 of the second plate-like member 3.

As another modification, in the embodiment described above, the third plate member 4 is overlapped with the front side surface of the second plate member 3, but as shown in FIG. It may be superimposed on the back side of the . The tabletop screen 1 shown in FIG. 8 can be assembled using the base material 10 shown in FIG. 9.

This modification is different from the above-described embodiment in that the first plate member 2 can be folded toward one side of the second plate member 3 along the crease L1 (mountain foldable in FIG. 9), and the third plate The shaped member 4 can be folded toward the other side of the second plate-shaped member 3 along the crease L2 (can be folded in a valley in FIG. 9).

Further, the pair of side surfaces 21 and 31 of the first plate-like member 2 and the second plate-like member 3 can be folded (mountain foldable in FIG. 9) with respect to the front parts 20 and 30 along a crease L3, and The plate-like member 3 can be bent to the side opposite to the surface on which the third plate-like member 4 is overlapped. The pair of side parts 41 of the third plate-like member 4 can be folded (can be valley-folded in FIG. 9) with respect to the front part 40 along a fold line L4, and the pair of side parts 41 of the first plate-like member 2 and the second plate-like member 3 The side parts 21 and 31 can be bent in the opposite direction in the state of the base material 10 shown in FIG. 9, and in the same direction in the state of the tabletop screen 1 shown in FIG. 8.

Furthermore, since the widths of the front parts 20 and 30 of the first plate member 2 and the second plate member 3 are shorter than the width of the front part 40 of the third plate member 4, the positions of the pair of folds L3 are different from each other. It is shifted inward from the position of the fold line L4. Here, since the pair of side surfaces 31 are displaced inwardly than the pair of side surfaces 41, the width of the second plate member 3 is shorter than the width of the third plate portion 4. Note that the width of the second plate member 3 may be equal to the width of the third plate portion 4. On the other hand, in the first plate-like member 2, since the width of the front part 20 is short and the width of the pair of side parts 21 is long, the width is equal to the width of the third plate-like part 4.

Further, as a connecting means, a protrusion 33 is provided on the outer edge of the side surface 31 of the second plate-like member 3, and a recess 43 that can engage with the protrusion 33 is provided on the side surface 41 of the third plate-like member 4. provided on the outer edge of the The convex portion 33 can be folded (can be valley-folded in FIG. 9) relative to the side surface portion 31 at the fold line L5. Note that the convex portion may be provided on the side surface portion 41 of the third plate-like member 4, and the recessed portion may be provided on the side surface portion 31 of the second plate-like member 3.

Furthermore, the window member 5 is attached to the back side surface of the second plate member 3.

Also in the tabletop screen 1 shown in FIG. ) are shifted in the left-right direction, and the side portions 31 and 41 on the same direction sides of the second plate-like member 3 and the third plate-like member 4 are bent toward the front side, and the connecting means (the concave portion 43 and the convex portion 33). As a result, the pair of side surfaces 31 of the second plate-like member 3 and the pair of side surfaces 21 of the first plate-like member 2 connected thereto are prevented from spreading toward the back in an attempt to return to their original state. As a result, the pair of side surfaces 21 of the first plate member 2 in contact with the tabletop are maintained in a V-shape with the front surface 20. Therefore, the tabletop screen 1 can be satisfactorily made to stand on its own during use, and it is possible to prevent the tabletop screen 1 from becoming unable to stand on its own and falling down during use.

In addition, after use, the engagement of the concave portion 43 and the convex portion 44 is released, and all the side surfaces 21, 31, 41 are opened to remove the first plate member 2, second plate member 3, and third plate member. After the member 4 is in a flat state, the first plate-like member 2 is folded back toward the front side and overlapped with the second plate-like member 3, thereby folding the tabletop screen 1 into a flat state (not shown). Can be made compact. Therefore, it is possible to save the storage space of the tabletop screen 1 when not in use, and it can be easily carried to, for example, a company conference room or a free space, as needed.

As another modification, in the above-described embodiments and modifications, the connecting means is realized by the engagement of the recess and the projection, but the side surface portions 31 of the second plate member 3 and the third plate member 4, The means for connecting 41 to each other is not limited to engagement.
