Description

  The present invention relates to a protective sheet for a hanging shaft that allows the mounting and dismounting of the protective sheet while the hanging shaft is hung between floors or in a display case of a museum.

  The conventional method of protecting the hanging shaft is to seal the coating surface with a transparent film sheet on both the front and back sides of the hanging shaft to protect the shaft from deformation caused by repeated weathering, dust, wetting and drying, and damage caused by insect bites. To do. (For example, refer to Patent Document 1). Alternatively, the entire surface, including hanging shafts and documented works, is impregnated with resin such as fluororesin to form a resin film to prevent the hanging shaft from being damaged by dust, dust, water droplets, oil droplets, and tobacco dust. There is a dirty shaft. (For example, refer to Patent Document 2). There is also a pinching type hanging shaft similar in shape to the present invention. The sandwich-type hanging shaft is intended for replacement of a printed work, and in order to enable replacement, a simple hanging shaft that can be removed by turning the transparent sheet is a structure that sandwiches the printed work between a base sheet and a transparent sheet. Yes (see, for example, Patent Document 3).

  Hereinafter, the structure of the hanging shaft (see the dotted line in FIG. 1) will be described. Looking at the cross-sectional shape of the hanging shaft (see FIG. 3), the left and right ends of the hanging shaft are about 3 mm, and the folded portion is called an inner fold, which is a treatment method that prevents fraying of the cut surface of the crack. When the hanging shaft is rolled up by this ear fold, a space is formed between the printed work surface and the back surface of the hanging work shaft, so that it serves as a spacer that holds the printed work in a hollow space and also serves as a packing material that prevents the inflow of air. . Due to the characteristic structure of the hanging shaft, it has been recently reviewed that it has a storage form excellent in storage and storage.

  The feature of holding the print work hollow by the thickness of the folded back of the ear fold is an advantage of the hanging shaft, and also a drawback. This advantage is maximized when the hanging shaft is new and flat without any uneven deformation immediately after repair.

  However, as the exhibition and appreciation is repeated, it is deformed under the influence of wetness and dryness. In addition, due to improper handling, such as holding the hanging shaft strongly or tightly tying the winding, a dent will be formed, causing creases and wrinkles. By repeatedly unwinding under deformed conditions, the surface of the work and the back of the hanging shaft come into contact with each other, rubbing and damaging the work.

  As a direct protective measure currently used for hanging scrolls, it is safe to use for many years such as wheat starch paste, laver paste, glue etc. First-aid treatment is performed using traditional materials that have been verified for sex. A protective sheet is sometimes sandwiched as a measure of minor damage to a printed work or as a measure to wait for full-scale repairs.

Japanese Patent Laid-Open No. 2002-417 JP-A-10-75859 JP-A-8-33545

  The conventional treatment method for protecting the hanging shaft described above is a seal coating treatment with a transparent film sheet, and the texture of the hanging shaft and the printed work surface becomes unclear over the transparent film sheet, This is not preferable for viewing because the glossiness changes. In addition, it is expected that the use of water impregnated with a resin such as a fluorine-based resin to add a water repellent function to a hanging shaft or a printed work will make it difficult to use water at the time of repair. In addition, since there are concerns over the aging and alteration of the resin, it is not suitable for prints and works that have value as cultural assets.

  Therefore, at present, a protective sheet is sandwiched at any time as a protective measure in accordance with the damage situation such as a hanging shaft, folding of a printed work, wrinkles, rubbing. There is also a protective measure called a thick winding shaft, which is attached so that the thick winding shaft is sandwiched between the shafts of the hanging shaft, and the shaft of the hanging shaft is apparently thickened so that it is difficult to be wound up.

  To attach or remove the protective sheet, it is essential to make the hanging shaft horizontal. Many hanging shafts that are affected by wetness or drying are deformed into irregular shapes. In order to attach the protective sheet to the hanging shaft deformed into an uneven shape, the protective sheet is easily crushed and wrinkled by the weight of the hanging shaft, even if both ends are rolled up by two people. Since wrinkles themselves are protrusions and cause rubbing, the protective sheet must be installed flat without wrinkles, but installation is difficult.

  In order to attach, remove, and detach the protective sheet in a horizontal state, a space is required for the operator to safely move the hanging shaft on the work table. In order to safely attach and detach the protective sheet, it is necessary for two persons to hold the both ends of the protective sheet, and it is necessary to arrange a plurality of workers. There are many problems to be solved, such as installation of work tables and securing of work space, and the difficulty increases as the size of the hanging shaft increases.

  In addition, when extending the hanging shaft on the tatami mat or on the floor, the working environment such as dirt, wetness and drying must be taken into consideration in advance, and the attachment and detachment of the protective sheet in a horizontal state has many problems.

  The present invention solves such a conventional problem and solves the problem of attaching and detaching the protective sheet in a horizontal state that is generally performed at present, in the vertical state at the place where the hanging shaft is hung. It is intended to be removable and removable.

[Means for Solving the Problems]
[0014]
In order to achieve the above-mentioned object, the present invention provides a beam that covers the front surface of the hanging shaft and that has a structure in which a plurality of sheets are stacked and is opposed to the hanging shaft on one side of the upper side of the protective sheet. It is a protective sheet characterized in that the sheet can be easily attached and detached, placed on the front surface of a hanging scroll in a vertical state, and unwound while sandwiching the protective sheet.

Further, the second solving means is characterized by having a conductive material.

  The operation of the first problem solving means is as follows. By attaching a bar to the protection sheet and attaching a hook, the structure can be hung the same as that of the hanging shaft. By hanging the hook of the protective sheet on the same bracket as that of the hanging shaft, it is horizontal. The protective sheet can be attached and detached in the vertical state. When a protective sheet is attached, the protective sheet and the hanging shaft in the vertical state are naturally lowered because they are pulled downward with a uniform force due to gravity, and the alignment of the protective sheet is protected from the center of the hanging shaft by the suspension structure. The center of the seat can be easily aligned, and it is difficult to wrinkle when it is rolled up.

  In addition, since the hanging shaft in the vertical state is pulled downward with a uniform force due to gravity, the hanging shaft of the hanging shaft that has been deformed due to the influence of wetness and drying is compared with the operation in which the uneven state of the wave is in the horizontal state. , In a direction to be relaxed. First of all, hold the head of the hanging shaft and start rolling up, then it is always pulled downward by a uniform force due to gravity, and the hanging shaft is naturally lowered.When you wind up while holding the protective sheet, the protective sheet is caught and the ears at both ends of the hanging shaft It is fixed in the space formed by the folded portion. Then, it is wrapped around the hanging shaft and stored in a storage box.

  Unwinding is repeated at every exhibition and appreciation, and even if the surface of the work and the back of the hanging shaft come into contact, it can be protected from damage such as rubbing by a protective sheet.

  When removing the protective sheet, after hanging the hook of the hanging shaft and the hook of the protective sheet on the same hanging metal fitting and unfolding them together, the hanging shaft and the protective sheet are naturally lowered by gravity. Next, after winding up on a paper tube attached to the protective sheet, it is stored in a storage box.

Further, operation of the above first means for solving problems is as follows. Even if there are a plurality of protective sheets, all the protective sheets are attached to the same crosspiece, so that the same protective sheet can be handled as a single sheet. Rather than using a single protective sheet, a plurality of protective sheets of different thicknesses are sandwiched to match the thickness of the folded back of the ear fold, thereby eliminating the space formed by the ear fold.

  By eliminating the space for the ear folds, it is possible to relieve and prevent dents caused by improper handling, such as firmly grasping the hanging shaft in the wound state and tightly tying the winding. Further, as another effect obtained by stacking a plurality of protective sheets, cushioning properties are improved because air is sandwiched between the protective sheets. Further, the friction between the protective sheets is reduced, which is more effective in preventing damage such as rubbing.

Further, operation of the above second problem solving means is as follows. When unwinding the hanging shaft, static electricity may be generated depending on the dry condition of the work environment. In particular, if static electricity is charged on the worker or the unwinding hanging shaft, there are concerns about unexpected situations such as adsorption of surrounding dust, fragile fragile print pieces, floating of paint fragments, sticking of protective sheets, etc. . In preparation for unforeseen circumstances, the protective sheet is made of a conductive material, so that the static electricity charged on the protective sheet, the hanging shaft, and the operator can be discharged by hanging the protective sheet.

  As described above, the attaching / detaching protective sheet for the hanging shaft according to the present invention attaches the crosspiece and the hook to the protecting sheet, which has been indispensable until the hanging shaft is horizontal in order to attach / detach the protecting sheet. As a result, the structure can be suspended. The hanging shaft can be unwound while sandwiching the protective sheet while being in a vertical state, and can be easily attached and detached. Installation of the protective sheet in the vertical state is evenly pulled down by gravity, so it is difficult to wrinkle, and the suspension structure makes it easy to align the center of the hanging shaft and the center of the protective sheet, and installation is easy. Features that can be accurately. Provided is a removable protection sheet for a hanging shaft that can be protected from damage such as rubbing caused by contact between the surface of a document work and the back surface of the hanging shaft.

  In addition, by overlapping multiple protective sheets, the space formed by the folded back of the ear fold is eliminated, and it is effective in mitigating and preventing dents caused by improper handling, such as holding the hanging shaft strongly and tightly tying the winding. It is. In the case where a plurality of protective sheets are stacked, the cushioning property is improved because air is sandwiched between the protective sheets. In addition, the air layer between the protective sheets can reduce the friction and provide an effective removable protective sheet for the hanging shaft by preventing damage such as rubbing.

  In preparation for unforeseen circumstances due to static electricity, the hook is made of a conductive material, so that the static electricity charged on the hanging shaft, the protective sheet, and the operator can be discharged by hanging it on the hanging bracket.

  The detachable protective sheet for the hanging shaft according to the present invention is not only applicable to the hanging shaft that has been damaged, but can also be used for a hanging shaft in a flat state without any new deformation of the cover. It can prevent damage due to improper handling, such as grasping firmly and tightly tying the cord.
