Sheet storage device

Abstract

To provide a sheet storage device capable of storing sheets without wrinkles or creases.SOLUTION: A sheet storage device 1 includes: a cylindrical bar 10 around which sheets 100 are wrapped: an axle 20 protruding from both the left and right ends of the bar in the axial direction; a holding portion 30 that holds the mandrel so that the bar can rotate freely around its axis; a semi-cylindrical fixing member 40 for fixing the starting end of a sheet to the bar; two disk-shaped operation plates 50 that a user operates when rotating the bar around the axis; and a box body 60. The operation plate is fixed to the axle, and includes a retracting space 70 between the left and right ends of the bar and the operation plate to position the folded-back portions of the seat side edge. Since the sheet is wrapped around the cylindrical bar, the sheet can be stored without creases. Since the folded parts on the side edges of the seat, the eyelets for threading strings, and the eyelet strings are located in the evacuation space, the sheet can be neatly wound up without causing wrinkles.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a sheet storage device that can store sheets without wrinkles or creases. [Background technology]

[0002] When sheet-like objects such as flags, banners, rolls of fabric, maps, and posters (hereinafter simply referred to as "sheets") are folded and stored in a cloud chamber, there is a problem that they may become wrinkled or creased when taken out. For example, Patent Document 1 discloses a technology that includes a flagpole with a groove and a flag that can be stored in the flagpole, where the flag is unfolded by pulling out the tip of the flagpole when in use, and the flag is stored inside the flagpole by rotating the tip of the flagpole when not in use. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-250166 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the technology of Patent Document 1 has a problem in that the end of the flag is fixed to a flagpole, and therefore the flag cannot be used by hanging it like a banner. In addition, flags and banners usually have a folded section where the side edge is folded in two and sewn, as well as grommets for threading a string through. However, when the flag is rolled up on a flagpole as in Patent Document 1, the folded section and grommets swell, which causes wrinkles in the flag.

[0005] In consideration of the above problems, an object of the present invention is to provide a sheet storage device that can store sheets without wrinkles or creases. [Means for solving the problem]

[0006] The sheet storage device of the present invention comprises a cylindrical bar around which the sheet is wrapped, a mandrel protruding axially from both left and right ends of the bar, a holding portion that holds the mandrel so that the bar can rotate freely around its axis, a semi-cylindrical fixing member for fixing the starting end of the sheet to the bar, an operating plate that the user operates when rotating the bar around its axis, and a box body, wherein the operating plate is fixed to the mandrel and has a retraction space between the left and right ends of the bar and the operating plate for positioning the folded portion of the side edge of the sheet. The mandrel is also characterized in being detachable from the bar. The bar is also characterized by having a through hole for discharging air from inside the bar to the outside. [Effects of the Invention]

[0007] In this invention, the sheet is wrapped around a cylindrical bar, so it can be stored without creases. In particular, the folded-over portions on the side edges of the sheet, the eyelets for threading the string, and the eyelet strings are located in the evacuation space, so the sheet can be stored without wrinkles or creases. By making the mandrel detachable from the bar, the internal space of the bar can be used effectively. By providing a through hole for discharging the air inside the bar to the outside, for example, an insect repellent or desiccant can be placed inside the bar, and the insect repellent ingredients or dry air can be discharged to the outside of the bar through the through hole. [Brief explanation of the drawings]

[0009] An embodiment of the sheet storage device of the present invention will be described below. The sheet storage device is used for storing rolled up sheets such as flags, banners, and rolls of fabric. As shown in FIGS. 1 and 2, the sheet storage device 1 includes a bar 10, a spindle 20, a holding portion 30, a fixing member 40, an operating plate 50, and a box body 60. The bar 10 is a cylindrical member around which the sheet 100 (FIG. 4) is wound. The longitudinal dimension of the bar 10 needs to be shorter than the width of the sheet 100 in the left-right direction.

[0010] As shown in Figure 3, the mandrel 20 is a member that protrudes in the axial direction from both the left and right ends of the bar 10. In this embodiment, the mandrel 20 is attached to a lid 12 that closes the end opening 11 of the bar 10. As shown in Figure 3(b), the lid 12 is designed to be removable from the bar 10, so that the mandrel 20 can be freely attached and detached to the bar 10. It is also possible to make the lid 12 fixed to the bar 10. 3(c), a configuration may be adopted in which the air inside the bar 10 can be discharged to the outside by providing a through-hole 13 in the lid 12. By placing an insect repellent or a desiccant inside the bar 10, the insect repellent ingredients and dry air can be discharged to the outside of the bar 10 through the through-hole 13.

[0011] The holding part 30 is a member for holding the mandrel 20 so that the bar 10 can rotate freely around its axis. Specifically, as shown in Figure 1(c), the holding part 30 has a recess 31, and by accommodating the mandrel 20 in this recess 31, the mandrel 20 and the bar 10 are held so that they can rotate freely around their axis. As shown in Figure 2, the fixing member 40 is semi-cylindrical and is a member for fixing the starting end 104 (Figure 4) of the sheet 100 to the bar 10. The radius of the fixing member 40 is the same as or slightly smaller than the radius of the bar 10. How to use the fixing member 40 will be described later. The operating plates 50 are two disk-shaped members that are operated by the user when rotating the bar 10 around its axis, and are fixed to the mandrel 20 as shown in FIGS. 3(a) and (b).

[0012] As shown in FIGS. 1(a) and 1(b), there are provided retraction spaces 70 between the left and right ends of the bar 10 and the operation plate 50 for positioning folded-back portions 101 (FIG. 5) of the seat side edges, etc. The box body 60 is a box with a lid 61 for storing the sheet 100, the bar 10, the mandrel 20, the holder 30, the fixing member 40 and the operation plate 50. The lid 61 is not shown in FIG.

[0013] Next, how to use the sheet storage device 1 will be described. First, as shown in Figures 4(a) and (b), the user places the starting end 104 of the sheet 100 on the surface of the bar 10, and then, while elastically expanding the diameter of the fixing member 40, fits the fixing member 40 onto the bar 10 so that it covers the starting end 104 of the sheet 100, as shown in Figures 4(c) and (d). This fixes the starting end 104 of the sheet 100 to the bar 10.

[0014] 5(a) and 5(b), the user rotates the operation plate 50 in one direction (the direction of the arrow) to rotate the bar 10 about its axis and wind the sheet 100 onto the bar 10. The side edges of the sheet have a folded portion 101, an eyelet portion 102 for threading a string, an eyelet string 103, etc., but as shown in FIG. 5(c), these folded portion 101, eyelet portion 102, and eyelet string 103 are located in the evacuation space 70, so the sheet 100 can be wound up neatly without wrinkles. Once the sheet 100 has been wound up to the end, the end 105 of the sheet 100 is secured by an arc-shaped stopper 80 as shown in FIG. 5(d), allowing the sheet 101 to be stored in the box 60 in a neatly wound state. To remove the sheet 100, remove the stopper 80 and pull the end 105 of the sheet 100 in one direction. By pulling the end 105 of the sheet 100, the bar 10 rotates around its axis while the sheet 100 is pulled out. [Industrial Applicability]

[0015] INDUSTRIAL APPLICABILITY The present invention is a sheet storage device that can store sheets without wrinkles or creases, and has industrial applicability. [Explanation of symbols]
