Embodiment 1

Figure 2 is a plan view of a guide tool used to determine the attachment position of an adhesive flag according to the first embodiment of the present invention. Hereinafter, a guide tool used to determine the attachment position of an adhesive flag according to an embodiment of the present invention will be described.

The guide tool 100 of the present invention includes a base sheet 110 in which an upper and lower alignment part 120, a left and right alignment part 130, and a page insertion sheet 150 are located on the same plane, as shown in FIG. 2. As such, the left and right alignment portions 130 protrude from a predetermined position in the longitudinal direction of the upper and lower alignment portions 120, for example, in the left and right directions from the center of the longitudinal direction, so that the base sheet 110 may adopt a structure having an overall T-shape. You can.

The upper and lower alignment portions 120 extend in the vertical direction and have graduations displayed on their surfaces. As shown in the drawing, the scale is based on the center of the upper and lower alignment portions 120, and the scales are formed symmetrically upward and downward, respectively. The scale facing upward is displayed so that its reference origin (0) coincides with the upper side 141 of the opening 140 of the left and right alignment part 130, which will be described later, and the scale facing downward has its reference origin point at the left and right alignment part 130. ) is displayed to match the lower side 142 of the opening 140.

The left and right alignment portions 130 protrude from the upper and lower alignment portions 120 in one left and right direction, and the left and right alignment portions 130 are formed integrally with the upper and lower alignment portions 120 to form one base sheet 110. You can. Figure 2 is an example showing an embodiment of the present invention. In the drawing, the left and right alignment unit 130 shows a configuration extending in the left direction from the left end of the upper and lower alignment unit 120. However, this is not limited to this, and the left and right alignment unit 130 It is also possible to adopt a structure in which the alignment unit 130 extends in the right direction from the right end of the upper and lower alignment unit 120. For reference, the guide tool 100 according to the present invention is generally used by inserting it into the right end of a specific page of a book or scheduler. In the present invention, the up and down direction refers to the up and down direction of the page, and the left and right direction refers to the left and right direction of the page. it means. However, when used at the top or bottom of the page, the top and bottom direction refers to the left and right directions of the page, and the left and right directions refer to the top and bottom directions of the page.

Meanwhile, an opening 140 is formed inside the left and right alignment parts 130. As will be explained in detail later, when the guide tool 100 is inserted into a specific page, the left and right alignment portions 130 cover the upper surface of the page, and the page insertion sheet 150, which will be described later, goes under the page, so that the left and right The opening 140 of the alignment unit 130 surrounds a certain area of the top surface of the page. After inserting the guide tool 100 into the page, the user aligns the flag within the area of the opening 140 and attaches it to the page. That is, the flag is aligned on the upper side 141 or the lower side 142 of the opening 140, and then the flag is attached to the area of the page exposed through the opening 140. That is, the opening 140 becomes a flag attachment area.

In addition, the upper side 141 and the lower side 142 of the opening 140 extend in a straight line in a direction perpendicular to the direction of the graduations of the upper and lower alignment portions 120. The scale of the top and bottom alignment part 120 forms a straight line along the top and bottom direction, and when the user inserts the guide tool 100 into a specific page, the scale direction of the top and bottom alignment part 120 is parallel to the edge of the page, for example, the right side. Sort it so that The upper side 141 and the lower side 142 of the opening 140 extend along a straight line perpendicular to the direction of the scale of the upper and lower alignment portion 120, so the upper side 141 and the lower side 142 of the opening 140 ) is perpendicular to one side of the page, for example, the right side.

The left and right alignment parts 130 protrude in one left and right direction from the upper and lower alignment parts 120, and the protruding part above the opening 140 is called an upper horizontal bar 131, and the protruding part below the opening 140 is called a lower horizontal bar. It is referred to as (132), and as shown, the upper horizontal bar 131 and the lower horizontal bar 132 of the left and right alignment portion 130 include the upper side 141 and the lower side 142 of the opening 140. A tick mark is displayed along at least one. The direction of the scales engraved on the upper horizontal bar 131 or the lower horizontal bar 132 is perpendicular to the direction of the scales of the upper and lower alignment parts 120.

Meanwhile, the opening 140 includes at least one side side 143 connecting the upper side 141 and the lower side 142. In the embodiment shown in the figure, the side side 143 is located on the upper and lower alignment portion 120. This is placed. On the side 143 toward the upper and lower alignment portion, the page insertion sheet 150 extends further from the upper and lower alignment portion 120 into the opening 140.

Figure 3 is a conceptual diagram explaining the process of inserting and fixing the guide tool of Figure 2 to the right side of the page. When the guide tool 100 of the present invention is inserted into a page, as shown in FIG. 3, the left and right alignment parts 130 cover the top of the page and the page insertion sheet 150 goes into the bottom of the page. That is, the page is fixed between the left and right alignment parts 130 and the page insertion sheet 150. The left and right alignment units 130 and the page insertion sheet 150 are sheet structures formed in the upper and lower alignment units 120, respectively. The left and right alignment units 130 are located upward with respect to the upper and lower alignment units 120, and the page insertion sheets ( 150) may be elastically bent downward with respect to the upper and lower alignment portions 120.

In this way, when the left and right alignment part 130 and the page insertion sheet 150 are spread apart and the guide tool 100 is inserted into a page of a book such that a specific page is placed between them, the page is aligned with the left and right alignment part 130 and the page. It enters between the fitting sheets 150, and the entry stops when the end of the page reaches the side 143 on the upper and lower alignment part 120 of the opening 140. At this time, the side 143 of the opening 140 may enter and be positioned inside the upper and lower alignment portion 120 in the width direction. If the position of the side edge 143 is designed like this, when the page stops entering, the right end of the page is placed on the left end of the upper and lower alignment part 120, as shown in FIG. 3.

Here, a portion of the upper and lower alignment portions 120 may be formed of a transparent material. Figure 4a is a conceptual diagram illustrating the process of inserting and fixing the guide tool 100 used to determine the attachment position of the adhesive flag according to a modification of the first embodiment of the present invention to the right side of the page. Referring to FIG. 4A, the left and right portions (T) of the upper and lower alignment portion 120 may be implemented with a transparent material. According to these conditions, the right end of the page passes through the transparent (T) left part of the top and bottom alignment unit 120 and is reflected to the user's eyes, and the user places the right end of the page on the grid of the top and bottom alignment unit 120. Since they can be arranged more closely, it is easier for the user to adjust one side of the page to be aligned at regular intervals with respect to the width direction line of the upper and lower alignment portion 120. Additionally, as shown, the longitudinal center of the upper and lower alignment portion 120, that is, the area T on the right side of the page insertion sheet 150, may also be implemented with a transparent material. This makes it easy to recognize how much the flag protrudes from the right edge of the page when attaching it. In addition, as shown in FIG. 2, a scale can be formed in the vertical direction in the right area (T) of the upper and lower alignment portion 120 to be used as a general ruler.

Meanwhile, the side side 143 of the opening 140 may be positioned to coincide with the width direction line of the upper and lower alignment portion 120, that is, the left side or right side of the upper and lower alignment portion 120. If the position of the side edge 143 is designed in this way, when the page stops entering, it is easy for the user to align one side of the page so that it coincides with the width direction line of the top and bottom alignment portion 120. At this time, at least one position adjustment protrusion may be provided along the width direction line of the upper and lower alignment portions 120 to protrude upward from the upper and lower alignment portions 120 . For example, on the left line in the width direction of the upper and lower alignment portion 120, one or more position adjustment protrusions may be disposed above the center in the longitudinal direction and one or more position adjustment protrusions may be disposed below the center in the longitudinal direction.

Meanwhile, Figure 8 is a photograph for explaining the process of determining the attachment position of the adhesive flag using the guide tool 100 according to the present invention. Referring to the drawing, the user inserts the guide tool 100 on the right side of a specific page of a book and adjusts the right end of the page to match the scale of the upper and lower alignment unit 120 to align the page and the guide tool 100 with each other. At this time, the alignment between the right edge of the page and the guide tool 100 can be checked by covering the book (left side of Figure 8), and the vertical distance from the previously attached flag can be checked by changing the page. At this time, if the vertical separation distance from the previously attached flag is different from the preset vertical separation distance, grasp the right side (T) of the upper and lower alignment part 120 of the guide tool 100 and then move the guide tool 100 up and down in parallel. Align the upper and lower spacing at the preset interval. Afterwards, the page with the flag attached is opened and attached to the exposed area through the opening 100. At this time, the scale of the upper side 141 of the opening 140 is checked so that the flag uniformly protrudes out of the right end of the page, and the left end of the flag is aligned to match the set scale. At the same time, the upper horizontal bar 132 of the opening 140 is aligned. ) and make sure that the flag is not distorted (center of Figure 8). By attaching the flag in this way, as shown on the right side of Figure 8, it can be accurately spaced up and down at the desired distance from the previously attached flags. Additionally, the flag can be attached so that it protrudes toward the right side of the page by the desired length, giving the flag a neat appearance. It can be attached easily.

Second embodiment

Figure 5 is a conceptual diagram of a guide tool 100 used to determine the attachment position of an adhesive flag according to a second embodiment of the present invention, and Figure 6 is a conceptual diagram showing the bottom of Figure 5. In addition, Figure 7 is a cross-sectional view for explaining the slide coupling structure of the extension member and the left and right alignment parts. The guide tool 100 according to the second embodiment of the present invention has a structure that further includes a U-shaped extension member 190 compared to the first embodiment. Accordingly, the second embodiment includes all the components according to the first embodiment, and the above description will be used for the same components as the first embodiment. Hereinafter, the description will focus on components additionally provided in the guide tool 100 according to the second embodiment.

In the guide tool 100 according to the second embodiment of the present invention, the U-shaped extension member 190 is fastened to be slidably movable with respect to the left and right alignment portions 130, and is overlapped with the left and right alignment portions 130 or the left and right alignment portions ( 130) and is configured to be separated by a preset distance.

In order to implement this drive, the guide tool 100 of the present invention first has a rail cover 170 formed on the bottom of the upper horizontal bar 131 and the lower horizontal bar 132 of the left and right alignment portions 130, respectively. . The rail cover 170 may be provided in the form of a sheet, and as shown in FIG. 6, the rail cover 170 formed on the upper horizontal bar 131 has a shape corresponding to the upper horizontal bar 131, and the lower The rail cover 170 formed on the horizontal bar 132 may have a size corresponding to the lower horizontal bar 132.

Meanwhile, a slide space 180 is provided between the rail cover 170 and the upper horizontal bar 131 and between the rail cover 170 and the lower horizontal bar 132, respectively. To this end, each rail cover 170 may be designed so that the inner thickness of the upper surface facing the horizontal bar is thinner than the outer thickness. A slide space 180 is formed between the bottom surface of the horizontal bar as the thickness of the rail cover 170 is lowered, and the leg 191 of the U-shaped extension member 190, which will be described later, can move in this space. It can be placed like this. Meanwhile, the rail cover 170 can also be fixed to the horizontal bar so that its upper surface remains spaced upward by a preset distance from the bottom of the horizontal bar. The space between the rail cover 170 and the horizontal bar forms a slide space 180, and the leg 191 of the U-shaped extension member 190 can be movably disposed in this space.

Meanwhile, the U-shaped extension member 190 includes a pair of legs 191. Each leg 191 is disposed in the above-described slide space 180, respectively. As the leg 191 is inserted and placed in the slide space 180, it is fastened to be able to slide with respect to the left and right alignment portion 130, and as the U-shaped connecting member moves toward the left and right alignment portion 130, for example, to the right, the left and right It is overlapped with the alignment unit 130 (left drawing of FIGS. 5 and 6), and on the contrary, as the U-shaped connecting member moves to the left, for example, away from the left and right alignment units 130, a preset distance is set from the left and right alignment units 130. (right drawing of Figures 5 and 6).

In this way, the U-shaped connecting member functions to extend the length of the left and right alignment portions 130 in the left and right directions. Specifically, graduations are formed on each leg 191 of the U-shaped connecting member. When the U-shaped connecting member extends furthest from the left and right alignment portions 130, the scales engraved on each leg 191 of the U-shaped connecting member are the upper horizontal bar 131 and the lower horizontal bar ( 132) is an extension of the scale. For example, if the upper horizontal bar 131 and the lower horizontal bar 132 are engraved with a scale of 1 cm to 9 cm, each leg 191 of the U-shaped connecting member may be engraved with a scale of 10 cm to 17 cm.

According to this configuration, the user fixes a specific page between the left and right alignment units 130 and the page insertion sheet 150 and moves the U-shaped connecting member in the slide space 180 in a direction away from the left and right alignment units 130. By pulling out, the predetermined size opening 140 of the left and right alignment portion 130 can be expanded larger by the length of the leg 191 of the U-shaped connecting member. Additionally, a flag can be attached within the expanded area, allowing the attachment location of the flag to be more freely selected in the left and right directions.

Meanwhile, a slit 171 is formed on the inside of each rail cover 170, and a stopper 192 protrudes from the end of each leg 191. When the leg 191 is placed in the slide space 180, the stopper 192 is placed in the slit 171 of the rail cover 170. As the stopper 192 is positioned within a certain range within the slit 171 of the rail cover 170, the U-shaped extension member 190 can be prevented from being separated from the slide space 180 in the left and right directions.
