  Therefore, in view of the above-described situation, the present invention intends to solve a thin-film screen sheet in a simple screen using a thin-film screen sheet made of paper or synthetic resin without requiring a separate storage container. A simple screen that can withstand repeated use by preventing tears, wrinkles, and dirt, and can be easily incinerated by the user, making it easy to use, lightweight, convenient to carry, and inexpensive to manufacture Is to provide

  In order to solve the above-mentioned problems, the present invention is provided with a thin film screen sheet made of paper or synthetic resin, a core member connected to a lower end side of the thin film screen sheet, and an upper end side of the thin film screen sheet. A simple type screen comprising a protective cover sheet made of paper or synthetic resin having a thickness larger than that of the thin film screen sheet is formed.

  Here, it is preferable that the protective cover sheet has a vertical dimension capable of covering at least the circumference of the thin film screen sheet wound around the core member over the entire circumference (Claim 2).

  The protective cover sheet preferably includes a screen suspension.

  Further, the protective cover sheet is configured to be folded in two so that the upper end side is folded back to the front side and the upper end side covers the upper end side of the thin-film screen sheet. It is preferable that a suspension hole is provided at each distance, and the suspension holes overlap each other in the two-fold state to function as a double suspension hole.

  Further, the core member is a paper or synthetic resin core material sheet having a thickness larger than that of the thin film screen sheet, and is continuously provided at the lower end side of the thin film screen sheet. It is preferable that the thin film screen sheet is wound on the sheet for use.

  Alternatively, the core member is a hollow cylindrical member made of paper or synthetic resin or a solid rod-like member connected to the lower end side of the thin-film screen sheet, and the cylindrical member or rod-like shape is stored when the screen is stored. It is preferable that the thin film screen sheet is wound on the member.

  Further, it is preferable that the core member and the protective cover sheet are made of cardboard or corrugated cardboard (Claim 7).

  Furthermore, it is preferable to provide a holding band for holding the protective cover sheet covering the thin film screen sheet wound around the core member in this state (Claim 8).

  According to the simplified screen of the first aspect, the thin film screen sheet is unfolded when the screen is used, and the core member connected to the lower end side is weighted to stretch the thin film screen sheet in a stable unfolded state. The entire screen can be installed on a wall or the like while maintaining the state and holding the protective cover sheet continuously provided on the other upper end side. Further, when storing, a thin film screen sheet is wound around the lower core member, and a protective cover sheet having a thickness larger than that of the thin film screen sheet is wound around the thin film screen sheet. The sheet functions as a protective member for the thin film screen sheet. Thereby, without using a separate storage container, the thin film screen sheet can be repeatedly used while preventing tearing, wrinkles and dirt.

  Furthermore, since the at least thin film screen sheet and the protective cover sheet are made of paper or synthetic resin, the simplified screen according to claim 1 is easily incinerated as a flammable material when it becomes unnecessary. Manufacturers and the like do not need to collect, manage, maintain, etc., and can be easily disseminated in one way that can be easily disposed of after use by the user. In addition, since it is also made of paper or synthetic resin, the material cost is low, the workability and assemblability are good, the manufacturing cost can be reduced, the overall weight is light, and no separate storage container is required as described above. Therefore, it is very convenient to carry.

  According to the simplified screen of the second aspect, the protective cover sheet completely covers the thin film screen sheet, and the thin film screen sheet can be reliably protected from external force and dirt.

  According to the simplified screen of the third aspect, since the protective cover sheet includes the screen hanging portion, the protective cover sheet is used in addition to the function of protecting the thin film screen sheet in addition to the function of hanging the entire screen. Without attaching the lowering means, the entire screen can be easily suspended and installed on the wall, ceiling, or other location, and the cost can be reduced by increasing the efficiency of the structure.

  According to the simplified screen of claim 4, the protective cover sheet is configured to be folded in two so that the upper end side is folded back to the front side and the upper end side covers the upper end side of the thin film screen sheet. It can hide the border with the sheet and improve the appearance design when using the screen. In addition, hanging holes are provided at equal distances from the folded position of the protective cover sheet folded in this way up and down, and these hanging holes overlap in the front and back in a double-folded state as double hanging holes. Since it functions, the burden concerning the hanging hole formed in the protective cover sheet made of paper or synthetic resin can be divided into two parts in the front and rear, and the durability of the screen hanging part can be improved.

  According to the simplified screen according to claim 5, the core member is a paper or synthetic resin core material sheet having a thickness larger than that of the thin film screen sheet, which is continuously provided on the lower end side of the thin film screen sheet. Since the thin film screen sheet is wound around the core sheet when the screen is stored, the entire screen can be made of paper or synthetic resin. It can be easily incinerated as a combustible material as it is, and can further reduce manufacturing costs and weight.

  According to the simplified screen according to claim 6, the core member is a hollow cylindrical member made of paper or synthetic resin or a solid rod-like member continuously provided on the lower end side of the thin film screen sheet. Since the thin film screen sheet is wound around the cylindrical member or rod-like member during storage, the entire screen can be made of paper or synthetic resin, facilitating incineration, reducing manufacturing costs, and lightweight. At the same time, it is not necessary to roll the core sheet, and the operability is improved, compared to the method in which the core sheet is rolled and then the thin film screen sheet is wound. This eliminates the wrapping of the core sheet and improves the appearance.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing the overall configuration of a simplified screen 1 according to the present invention. FIGS. 1 to 4 show a first embodiment, FIGS. 5 to 8 show a second embodiment, and reference numeral 2 in FIG. Are thin film screen sheets, 3 is a core member, and 4 is a protective cover sheet.

  As shown in FIG. 1, the simplified screen 1 of the present invention includes a thin film screen sheet 2 made of paper or synthetic resin, a core member 3 connected to the lower end side 2 b of the thin film screen sheet 2, and a thin film screen sheet 2. Paper having a vertical dimension capable of covering the entire circumference of at least the thin film screen sheet 2 wound around the core member 3 and being thicker than the thin film screen sheet 2. And a protective cover sheet 4 made of synthetic resin or synthetic resin.

  When the screen is used, as shown in FIG. 4, the core member 3 at the lower end is weighted to maintain the thin film screen sheet 2 in a stable unfolded state while the thin film screen sheet 2 is unfolded. The entire screen can be installed on a wall or the like while holding the protective cover sheet 4 on the side. Further, at the time of storage, the thin film screen sheet 2 is wound around the lower core member 3 as shown in FIGS. 2 to 3, and the protective cover sheet 4 is wound around the outer side of the thin film screen sheet 2. The protective cover sheet 4 functions as a protective member for the thin film screen sheet 2. Thereby, it is possible to reliably prevent the thin film screen sheet 2 from being broken, wrinkled, and dirty without requiring a separate storage container.

  The simplified screen 1 of the present invention is not only configured as an image screen for projecting an image from a projector or the like, but is also used as an advertising sheet or the like by displaying a picture or the like on a awning screen provided in a window or a thin film screen sheet. It can also be configured as an advertising screen to be used.

  First, based on FIGS. 1-4, 1st Embodiment of this invention is described.

  In the screen 1 of the present embodiment, the thin film screen sheet 2, the sheet-like core member 3, and the protective cover sheet 4 are all made of paper, and of course can be recovered and reused as used paper. However, not all are made of paper, but for example, the thin film screen sheet 2 may be made of a synthetic resin film such as PET, or a sheet obtained by laminating and combining a paper sheet and a synthetic resin film. The protective cover sheet 4 may also be a synthetic resin sheet, or a combination of a paper sheet and a synthetic resin sheet stacked together. Moreover, you may comprise by synthetic rubber, metal, and a wooden sheet | seat. Further, the sheet-like core member 3 can be made of various materials such as a synthetic resin, a synthetic rubber, a metal, and a wooden sheet in addition to the paper.

  The thin film screen sheet 2 is made of a rectangular paper sheet as shown in FIG. 1, and the vertical and horizontal dimensions can be set as appropriate. The upper end portion of the core member 3 is bonded to the back surface side of the lower end side 2b of the thin film screen sheet 2 with an adhesive or a double-sided tape, and the protective cover sheet 4 is attached to the back surface side of the upper end side 2a of the thin film screen sheet 2. The lower end is also bonded with an adhesive or double-sided tape. Of course, it is also possible to join using a stapler or other connecting means.

  The core member 3 is composed of the same rectangular core sheet 30 having a thickness larger than that of the thin film screen sheet 2, and the thin film is formed such that left and right end portions protrude outward from the left and right end portions of the thin film screen sheet 2. The left and right dimensions are set wider than the screen sheet 2. At the time of storing the screen, as shown in FIG. 2, first, the core sheet 30 is wound, and then the thin film screen sheet 2 is continuously wound. In particular, in this example, the core material sheet 30 is a corrugated cardboard sheet, and when stored, the thin film screen sheet 2 is further wound after the core sheet 30 is rolled up so as to be annular in cross section. When the core material sheet 30 is a corrugated cardboard sheet as in this example, it is inevitably rounded into a polygonal shape instead of being rounded into a clean circle. ) Is preferable because it can be smoothly rounded.

  It is also preferable to select a cardboard such as a paperboard having a thickness larger than that of the thin film screen sheet 2 instead of the cardboard sheet. Since such cardboard is not a hollow three-dimensional structure like a cardboard sheet, it can be easily rolled into a clean circle when stored. Such a circular shape is preferable in that the thin film screen sheet 2 wound around the outer surface is less likely to be wrinkled. In this example, the core sheet 30 is rounded in a cross-sectional view when stored, but may be rounded into a substantially C shape in cross-section by setting a shorter vertical dimension. Even such a C-shape is thick and relatively strong, and therefore functions sufficiently as a core material around which the thin film screen sheet 2 is wound. Of course, it is preferable to have a vertical dimension that can be rounded like the present example because it is difficult to cause wrinkles when the thin film screen sheet 2 is wound. Such a core sheet 30 is thick but thick, and thus has a function of stretching the thin film screen sheet 2 as a weight when the screen is unfolded.

  The protective cover sheet 4 is made of a corrugated cardboard sheet that is rectangular and thicker than the thin-film screen sheet 2, as with the core member 3, and when the screen is stored, as shown in FIG. The corrugated cardboard sheet covers the periphery of the thin film screen sheet 2 wound thereon to protect the thin film screen sheet 2. For this reason, preferably, the upper and lower dimensions have a length that can cover at least the entire circumference of the thin film screen sheet 2 when the screen is stored, and the left and right end portions of the thin film screen sheet 2 are also left and right. It is set to be wide so as to protrude outward from the left and right end portions, and is configured so as to completely cover the easily tearable thin film screen sheet 2 during storage and to protect it from external force.

  In this example, the protective cover sheet 4 is preliminarily provided with four fold lines 41 so as to be rounded into a box shape having a quadrangular view when the screen is stored. Thus, the protective cover sheet 4 rolled into a box shape has a higher shape retaining property and a function of protecting the internal thin film screen sheet 2 against an external force. It is also preferable to provide a crease (such as a crease or a shallow fold groove) so as to be rounded into, for example, a pentagon in a cross-sectional view or other shapes in addition to a square in a cross-sectional view. In addition, instead of the corrugated cardboard sheet, it is also preferable to select cardboard such as paperboard having a thickness larger than that of the thin film screen sheet 2 as in the second embodiment described later.

  In this example, a holding band 5 is provided for holding the protective cover sheet 4 covering the thin film screen sheet 2 when the screen is stored in this state. The holding band 5 is made of a band-shaped member with a hook-and-loop fastener and is prepared separately from the protective cover sheet 4. However, the holding band 5 may be fixed to the protective cover sheet in advance. A string or the like may be used instead of the holding band. Further, an engaging portion such as a hook-and-loop fastener may be provided in advance on the protective cover sheet 4 itself, for example, on the upper and lower ends.

  Further, when the protective cover sheet 4 is used as a screen, as shown in FIG. 4, the upper end 4a side is folded back to the front side, and the upper end 4a side is used so as to cover the thin film screen sheet upper end side 2a from the front side. Here, the second fold 41 from the top among the folds 41 for rounding at the time of storage is folded back into two. By covering the thin film screen sheet upper end side 2a with the protective cover sheet 4 in this way, the boundary portion between the screen sheet and the protective cover sheet 4 can be hidden, and the appearance design when using the screen can be improved.

  The protective cover sheet 4 is provided with a hanging hole 42 as the screen hanging portion 10 used when the entire screen is suspended from a wall or the like. The left and right opening positions may be only the center or only the right and left target positions, but in this example, a pair of upper and lower suspension holes 42 are provided at positions symmetrical to the center portion. The suspension holes 42 are respectively provided at equal distances in the vertical direction from the folding position when the screen of the protective cover sheet 4 is used (in this example, the second fold line 41 from the top). In the two-fold state, the suspension holes 42 overlap in the front and rear directions and function as double suspension holes 42. The suspension holes 42 are supported by being suspended on a wall or ceiling using hooks, strings, or the like. can do. Thus, by using as the double suspension hole 42, durability of the screen suspension part 10 made of paper can be enhanced.

  In this embodiment, the protective cover sheet 4 is folded back during use to hide the boundary portion with the screen sheet. However, it is of course possible to use the protective cover sheet 4 without folding. In this case, it is not necessary to provide the hanging holes 42 in a pair. In addition, the screen of the present embodiment may be used by placing a stand for holding a protective cover sheet on a floor or a table. Further, instead of providing the screen hanging portion on the protective cover sheet itself, a screen hanging tool for hanging the screen may be separately attached to the upper end portion of the protective cover sheet.

  Next, a second embodiment of the present invention will be described based on FIGS.

  In the present embodiment, instead of using the core material sheet 30 as the core member 3, a hollow cylindrical member 31 or a solid rod-shaped member is continuously provided on the lower end side of the thin film screen sheet, and the screen storage Since the thin film screen sheet 2 is sometimes wound on the cylindrical member 31 or the rod-shaped member, the work of rolling the core material sheet is unnecessary as compared with the case where the thin film screen sheet 2 is wound after the core material sheet 30 is rolled. In addition, the smooth curved outer peripheral surface (cylindrical shape, columnar shape, etc.) has an advantage that the thin film screen sheet 2 wound thereon is less likely to be wrinkled.

  In this example, only the paper cylindrical member 31 is used, but a shaft or a tube made of other materials (synthetic resin, metal, wood, etc.) may be stacked inside and outside. It may be a metal tube (for example, aluminum) or an outer peripheral part of a core of a rod, and a paper tubular body detachably mounted. In this case, the core body may be reused, and the outer cylindrical body, the thin film screen sheet 2 and the protective cover sheet 4 connected thereto may be newly replaced. However, it is preferable to use synthetic resin or paper that can be easily discarded.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention.
