Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention enables easy and reliable pattern matching without making mistakes in the vertical direction when pasting pieces of wallpaper onto walls as part of interior construction work for buildings. Regarding the structure of wallpaper that can be made.

[Conventional technology]

In recent years, construction of large buildings, hotels, public halls, new towns, etc. has been active, and wallpapering of walls as part of interior construction work is required to be carried out and completed in a short period of time.

What is wallpaper as a commodity commonly offered for trade?
Width with a fixed length on one side - 90~ which can usually be handled with both hands
In the industry, a pattern planned by the trader is regularly repeated in a fixed area vertically and horizontally on a rectangular rectangle, often around 120 cm long, with the other sides of irregular lengths, usually around 50 meters. This is called a repeat (unit).The weave is a printed sheet backed with a different type of paper and made into a roll.

Both edges of the indefinite length are called selvages (portions); in other words, the total width of a certain length of the wallpaper can be expressed as consisting of the effective width of the pattern and the selvage widths on both sides.

The current method of pasting wallpaper is to first roll out a roll of wallpaper, cut it to match the length of the wall from the ceiling to the floor, and at the same time glue the back side manually or by machine, and then A method is used in which the scrolls are successively pasted at intervals of a fixed length, that is, 90 to 120 cm, and when the scroll is used up midway through, a so-called body joint is sometimes performed in which the scrolls are joined between the top and bottom.

When pasting this wallpaper together, overlap the edges of the left and right wallpapers so that the designs on both sides are aligned vertically.
The left and right sides are connected accurately without any deviation - this is called pattern matching in the industry - and the layered ears are cut off using a cutter and a ruler, but the recent trend in patterns is that at first glance, it is difficult to see where they start and end. One repeat unit, or even one in which it is unclear which direction is the top direction, is preferred, and it is not so easy to match this pattern accurately, even for highly skilled craftsmen. Ta.

In other words, in wallpapering, which requires repeated work to cover a large amount of wall surfaces within a set time, pattern matching requires the most nerve and fatigue of the craftsmen, which naturally leads to a decrease in efficiency. In addition, it is known that mistakes in the top and bottom of wallpaper can easily occur due to changes in craftsmen, and it is not uncommon for orders to be re-installed due to this, so it is important to establish this countermeasure. was a common request in the industry.

[Means for solving problems]

The present invention has been proposed in response to the above-mentioned industry needs.

To explain the configuration of the present invention shown in FIG. 1 with reference to the accompanying drawings, the total width a of the wallpaper 1 of the present invention is the same as the conventional wallpaper, the effective width b of the pattern and the edge width 2 on both sides thereof. It consists of

Therefore, at arbitrary intervals along the undefined long sides, the upper and lower direction indicating symbols (hereinafter referred to as the upper and lower marks) in the form of arbitrary shapes indicating the upward direction, such as arrows, are placed on the both ear portions 2. A pattern matching instruction symbol 4 (hereinafter referred to as a joint mark) in any form that should serve as a guide when each wallpaper piece is horizontally matched and pasted according to the effective width of the design;
For example, a triangle, a horizontal arrow, a straight line, a broken line, etc. are displayed.

In this case, the top and bottom marks and joint marks on the left and right ears do not necessarily need to be displayed in symmetrical positions, but may be displayed in different positions on the left and right as long as they fulfill the instruction function described below. There is no problem.

Here, while explaining how to use wallpaper 1 of the present invention, the function of the joint mark will be described as follows.
Assuming that you are pasting the wallpaper pieces from left to right on the wall, first paste the left edge part 2 of the first wallpaper piece.
Cut it out with a cutter and a ruler and paste it on the wall. Next, the boundary line 6 between the effective part of the pattern and the right edge part 2 (indicated by the two-dot chain line in Figure 1) is changed to the boundary line 6 between the left edge part of the second piece of wallpaper and the effective part of the pattern.
The layered edges 2 are cut off with a cutter along the border line 6, but in this case, the joint mark 4 (in the drawing) on the right edge of the first wallpaper piece is cut off. By overlapping both pieces of wallpaper using the joint mark 4 on the left edge of the second wallpaper piece as a guide, pattern matching can be easily, quickly and accurately achieved.

In other words, the joint mark of the present invention is a mark that directly or indirectly indicates the position of the boundary line between one of the edges 2 and the effective part of the pattern on the inside of the edge of the wallpaper piece, and also indicates the position of one repeat unit. The key point of the present invention is to install the device so as to directly or indirectly indicate the vertical position of a specific point in the pattern.

As mentioned above, this joint mark has been defined in this specification as something that can be used as a "guide" for pattern matching, but its meaning is that it directly indicates the position of the border line and a specific point in the pattern of one repeat unit. This means that the location is not necessarily indicated, and may indirectly indicate the location. For example, in Fig. 1, the tip of the joint mark 4 is located a certain short distance c from the boundary line 6, but this is because when cutting off the ear part along the inner boundary line 6, This has the advantage of avoiding unsightly stains on the wallpaper surface due to joint marks left behind. However, in the case of this indirect display, it is necessary to separately state on the product that ``cutting is done by overlapping the inside part by a distance c from the edge of the joint mark''.

Note that this joint mark can be used as a guide for matching patterns even if it is on a piece of wallpaper cut from any part of a scroll-shaped wallpaper of indefinite length.

Furthermore, when overlapping and cutting the boundary lines on the first and second wallpaper pieces using the joint marks as a guide, it is possible to use a non-adhesive vinyl board or joint tape as an underlay in advance so that the wall surface can be avoided.

In this way, the third and subsequent wallpaper pieces are successively pasted on.

〔Effect of the invention〕

The method of pasting wallpaper pieces together using the top and bottom marks and joint marks of the present invention as a guide allows craftsmen to work reliably, skillfully, and smoothly without having to pay extra attention to the top and bottom directions and pattern alignment, which makes it easier to use the conventional method. This makes it possible to significantly improve work efficiency.
