Description

  The present invention relates to a marking cover and a marking device that can perform maintenance for recovering the display state of various signs in a marking device such as a railway track in a short time without using a maintenance tool or the like.

  On railway tracks and highways, for example, alongside the tracks, signage devices that display track features such as numbers and symbols are installed. Symbols are, for example, distance markers, curve markers, gradient markers, etc., which are necessary for safe driving and maintenance, and are provided at various points on the track. In addition, it is possible to check the operating conditions of the local points.

  The marking device is attached to a wall such as a protective wall on the side of the track, such as in a tunnel or an elevated track. The marking device attached to the wall is a boundary between the first display surface seen from the upside and the second display surface seen from the downside so that the signs of the signs can be seen by both the up and down train drivers. There is known a vertical flat display substrate that is bent vertically at both ends fixed to a wall surface (see, for example, Patent Document 1).

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a sign cover according to the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1 to FIG. 5, the sign cover 1 of the present embodiment has a sign part 3 on which the marks 7 are displayed on the front surface, and is folded back at the upper end of the sign part 3 to the back surface of the sign part 3. The overlapping back surface portion 4, in the example shown in the figure, a part of the lower end of the back surface portion 4 is folded back toward the marking portion 3 side and extends upward, and a slit 6 provided below the marking portion 3. I have. Although not shown, the engaging piece 5 may be provided at the lower end of the marking portion 3 and the slit 6 may be provided below the back surface portion 4 instead of the above-described form.

  The marking part 3 is formed in a flat plate shape, for example, a rectangular flat plate shape. The length in the vertical direction (height direction) of the marking portion 3 is longer than the length of the longest vertical substrate in the existing vertical flat plate-like display substrate 11 (see FIGS. 4 and 5). It is preferable that the length is slightly longer. The length of the marking portion 3 in the horizontal direction (width direction) is shorter than the length of the shortest substrate in the horizontal direction among the existing display substrates 11, and is formed to have a slightly shorter dimension, for example. Note that a plurality of marking covers 1 may be formed for each type of the existing display substrate 11. On the surface of the marking part 3, various marks 7 such as a distance mark, a curve mark, and a gradient mark are displayed. The means for displaying the symbols 7 is not particularly limited, and the symbols 7 are displayed using well-known means such as handwriting or a transfer sheet.

  The back surface portion 4 is formed in a flat plate shape that is folded back at the upper end of the marking portion 3 and overlaps the back surface of the marking portion 3, for example, a rectangular flat plate shape. The length in the vertical direction (height direction) of the back surface portion 4 is preferably formed with the same dimensions as the marking portion 3. As long as the length of the rectangle of the back surface portion 4 is the same as that of the marking portion 3 in the vertical direction, the width may be different from that of the marking portion 3, but the rectangular shape is substantially the same as that of the marking portion 3. It is preferable that The same marks 7 displayed on the surface of the marking unit 3 may be displayed on the outer surface of the back surface 4 (the surface opposite to the surface facing the back surface of the marking unit 3). Good. If it carries out like this, since the same marks 7 are displayed on the surface of the marking part 3 and the back surface part 4, both marks 7 can be used. As a result, if the visibility of the marking 7 on the marking portion 3 side is reduced and the display of the marking 7 becomes invisible to the driver even after cleaning, the marking 7 on the back surface portion 4 side is displayed. Therefore, maintenance can be performed without having to provide another marking cover 1.

  A part of the lower end of the back surface portion 4 is formed as an engagement piece 5 that is folded back toward the marking portion 3 and extends upward. For example, one engagement piece 5 is formed at an arbitrary width at the center of the lower end of the back surface portion 4. In addition, although the engagement piece 5 is formed in the center part of the lower end of the back surface part 4, it is not limited to this, Two or more may be sufficient. Further, the engaging piece 5 may be formed on a part of the lower end of the marking portion 3 instead of being provided on the back surface portion 4.

  A slit 6 extending in the lateral direction (width direction) is provided below the marking portion 3. The slit 6 is for engaging and holding the engagement piece 5 by inserting the engagement piece 5. The slit 6 is arbitrarily set to a position and a width where it is difficult to release the engagement state in which the engagement piece 5 is inserted.

  The marking portion 3, the back surface portion 4, and the engagement piece 5 are integrally formed as a plate-like cover body 2 by an elastically deformable plate material, for example, a flat plate material such as synthetic resin. That is, for example, the plate-like cover body 2 is formed by punching out a forming portion of the unfolded marking portion 3, a forming portion of the back surface portion 4, and a forming portion of the engagement piece 5 from an elastically deformable synthetic resin plate material. A plate-like cover sheet body is formed, and this sheet body is bent and formed. The unfolded plate-like cover body 2 is bent at the upper ends of the marking portion 3 and the back surface portion 4 so that the marking portion 3 faces the front surface side of the display substrate 11 and the back surface portion 4 faces the back surface side of the display substrate 11. Then, the cover 5 is placed on the display substrate 11 by inserting the engagement piece 5 bent toward the marking portion 3 side into the slit 6 of the marking portion 3 after being put on the display substrate 11.

  As shown in FIG. 2, it is preferable to provide convex pieces 8 projecting left and right at the distal end sides on both the left and right sides of the distal end. Although the dimension which protrudes from the both sides of the engagement piece 5 of the convex piece 8 is not specifically limited, The length (width) between the front-end | tips which the two convex pieces 8 protrude is formed in a dimension a little larger than the left-right width of the slit 6. It is preferable. The shape of the convex piece 8 may be a rectangular shape or other shapes, but is preferably formed in a rectangular shape, a triangular shape, or the like in which the side portion 8a on the distal end side of the engaging piece 5 of the convex piece 8 is inclined. In the present invention, when the engaging piece 5 is provided with the convex piece 8, the left and right ends of the slit 6 are inclined upward or downward with respect to the horizontal slit 6 which is equivalent to the horizontal width of the convex piece 8. You may make it form the extended slit part. When the slit extension portion inserts the engagement piece 5 into the slit 6, when the left and right convex pieces 8 are inclined according to the inclination of the slit extension portion and inserted into the slit extension portion, the inclination of the convex piece 8 is returned. The convex piece 8 cannot be removed from the slit extension portion.

  Moreover, as shown in FIG. 3, it is preferable to integrally provide two tongue pieces 9 that are folded back on the back surface portion 4 side on both sides of the lower end of the marking portion 3 that are not covered with the engagement piece 5. The length of the tongue piece 9 is formed such that when the plate-like cover body 2 is attached to the display substrate 11, the tongue piece 9 can be positioned on the front surface side of the back surface portion 4 beyond the lower end of the substrate 11. Accordingly, when the engagement piece 5 is inserted into the slit 6 after the plate-shaped cover body 2 is put on the display substrate 11, the two tongue pieces 9 are placed between the display substrate 11 and the back surface portion 4 or between the back surface portion 4. It can be located on the outer surface.

  Next, the case where the display cover 1 of the present embodiment configured as described above is attached to the display substrate 11 will be described. As shown in FIG. 5A, the display substrate 11 is already attached to a wall (not shown) and has a vertical flat plate shape bent at the boundary line ab between the first display surface A and the second display surface B. Both ends of the display substrate 11 are fixed to the wall surface with bolts b or the like, and in the example of FIG. 5, both the first and second display surfaces A and B require maintenance of the indicators 7. And

  As shown in FIG. 5B, the plate-like cover body 2 is placed on the display substrate 11 on the first surface A side from the top, for example, with the engagement piece 5 positioned on the back surface side of the marking portion 3. 3 is placed so as to face the front surface side of the display substrate 11 and the back surface portion 4 faces the back surface side of the display substrate 11. After the covering, as shown in FIG. 5C, the engaging piece 5 at the lower end of the back surface portion 4 is brought in front of the indicating portion 3 beyond the lower ends of the display substrate 11 and the indicating portion 3. In other words, the portion of the engagement piece 5 that is folded back from the lower end of the back surface portion 4 that is the base portion of the engagement piece 5 is bent against the elastic force.

  The engagement piece 5 returns to its original shape due to the elastic force, but as shown in FIG. 5 (d), it is generally shallow so that the middle of the marking portion 3 is slightly lifted from the display surface A against the elastic force. A state of being bent in a letter shape is created, and the engagement piece 5 is inserted into the slit 6. When inserted, the force that bends the marking portion 3 is released. In addition, you may bend in order to insert the engagement piece 5 in the slit 6 simultaneously with the curve of the marking part 3. FIG. When the bending force applied to the marking portion 3 is released, the marking portion 3 returns to the original substantially flat plate shape due to the elastic force, and the engagement piece 5 is inserted deeply into the slit 6 to be engaged (see FIG. 4). Thereby, the plate-like cover body 2 is attached to the display substrate 11 on the first display surface A side. When maintenance is also necessary for the display substrate 11 on the second display surface B side, another plate cover body 2 is put on the display substrate 11 on the second display surface B side and engaged in the same manner as described above. By inserting the piece 5 into the slit 6, as shown in FIG. 4, the marking cover 1 can be attached to the display substrate 11 on the second display surface B side. FIG. 4 shows a state in which both the first and second display surfaces A and B are maintained by the marking cover 1 of the present embodiment.

  As described above, the sign cover 1 of the present embodiment is attached to the display substrate 11 simply by covering the plate cover 2 with the display substrate 11 and inserting the engagement piece 5 into the slit 6. Maintenance can be performed in a short time without using a maintenance tool such as a dedicated tool. Further, when changing the display contents of the symbols 7 displayed on the display board 11, it is possible to change the symbols 7 only by attaching the display cover 1 displaying the symbols 7 to be changed to the display board 11. Thus, in the case of changing the marking, the symbols 7 can be easily changed in a short time using the original display substrate 11 as in the case of maintenance. In particular, when installing in a dark place such as in a tunnel or where the foot of the ballast is unintentional, a mounting part such as a screw may be required in addition to the marking body. There were many fears of dropping and losing. However, the marking cover 1 of the present embodiment does not require any attachment parts because it does not require any attachment parts. In addition, the marking portion 3 and the back surface portion 4 have a length in the height direction that is longer than the length of the longest substrate among the existing display substrates 11, and a horizontal length that is one of the existing display substrates 11. Since it is formed shorter than the length of the shortest substrate, the marking cover 1 of this embodiment can be attached to all display substrates 11 having different sizes.

  In addition, when the engagement piece 5 is provided in the back surface part 4 and the slit 6 is provided in the marking part 3, it is easier to insert the engagement piece 5 into the slit 6 than when the engagement piece 5 is provided in the marking part 3. Further, when the protruding pieces 8 protruding from the width of the slit 6 are provided at both ends of the engaging piece 5, the protruding piece 8 acts as a stopper and the engaging piece 5 is difficult to be removed from the slit 6. The engagement state of the engagement piece 5 can be maintained for a long time. Further, two tongue pieces 9 are provided on both sides of the lower end of the marking portion 3, and the tongue piece 9 is displayed when the engagement piece 5 is inserted into the slit 6 after the plate-like cover body 2 is put on the display substrate 11. By being positioned between the substrate 11 and the back surface portion 4 or on the outer surface of the back surface portion 4, the marking portion 3 is lifted from the display substrate 11 by the wind pressure, particularly when the train passes, and the engagement piece 5 is slit 6. As a result, the engagement state between the slit 6 and the engagement piece 5 can be maintained for a long time.

  Further, in the present invention, as shown in FIG. 6, the boundary between the back surface parts 4 of the two plate-like cover bodies 2 or between the marking parts 3, for example, the two back face parts 4, 4 of the two plate-like cover bodies 2. The sign cover 10 may be configured by being integrally formed so that it can be bent. When the sign cover 10 in which the two plate-like cover bodies 2 are integrally formed as described above is configured, the vertical flat display substrate 11 bent at the boundary between the first display surface A and the second display surface B of the display substrate 11 is formed. When the plate-like cover body 2 is attached to both the display surfaces A and B, it can be easily attached in a shorter time than when the plate-like cover body 2 is individually attached.

  That is, the two plate-like cover bodies 2 and 2 of the marking cover 10 are bent at the boundary 10a between the back surface portions 4 and 4 at substantially the same angle as the bent angle between the first display surface A and the second display surface B of the display substrate 11. . The two plate-like cover bodies 2 and 2 that are bent face each of the display portions 3 and 3 facing the two display surfaces A and B of the display substrate 11, respectively, and the respective back surface portions 4 and 4 are the back surfaces of the display substrate 11. Cover to face side. The engaging pieces 5 and 5 are brought forward from the lower ends of the marking portions 3 and 3 and the display substrate 11, and the engaging pieces 5 and 5 are inserted into the slits 6 and 6 of the marking portions 3 and 3, respectively. Thereby, the sign cover 10 can be attached to both the first display surface A and the second display surface B of the display substrate 11 at a time, and when the plate-like cover body 2 is individually attached to each display surface. In comparison, it can be easily installed in a short time.

  The marking device according to the present embodiment includes the above-described marking cover 1 and a vertical flat-plate-shaped display substrate taking the display substrate 11 to which the marking cover 1 is attached as an example. The display substrate is formed in a vertical flat plate shape whose both side portions can be fixed to the wall with, for example, bolts and the sign cover 1 of the present embodiment can be mounted between the both side portions, such as an existing one made of aluminum or the like. Can be used. The number of display covers 1 attached to the display substrate is not particularly limited, and may be one or two or more. For example, assuming that the number of the sign covers 1 is two, the display substrate is formed in a vertical flat plate bent at the boundary between the first display surface and the second display surface, and both ends are fixed to the wall surface with bolts or the like. It is what is done.

  As described above, the marking device according to the present embodiment is configured by the marking cover 1 and the display substrate. First, both ends of the display substrate are fixed to the wall surface with bolts or the like, and then the display substrate on the first display surface side. In the same manner as described above, the indication cover 1 is put on and the engagement piece 5 is inserted into the slit 6 to attach the indication cover 1 to the display substrate on the first display surface side. After the mounting, the display board on the second display surface side is covered with another display cover 1 in the same manner as described above, and the engagement piece 5 is inserted into the slit 6, thereby the display cover 1 on the display board on the second display surface side. Is installed.

  In the marking device of the present embodiment, even if the display surface (the various marks 7) of the mounted sign cover 1 is cleaned, the display of the various marks 7 becomes difficult for the driver to visually recognize. When changing the display content of the mark 7, first, the engagement piece 5 is removed from the slit 6 of the attached sign cover 1, and the engagement piece 5 is positioned between the display substrate and the back surface portion 4. Later, the marking cover 1 is moved upward to remove the marking cover 1 from the display board. Next, the new marking cover 1 is put on the display board in the same manner as described above, and the engagement piece 5 is inserted into the slit 6. By doing so, the new marking cover 1 can be attached to the display substrate.

  By configuring the marking device of the present embodiment as described above, the marking device of the present embodiment has the same operational effects as the marking cover 1 of the present embodiment described above. For example, the marking device according to the present embodiment can perform maintenance of the marking device in a short time without using a maintenance tool such as a dedicated tool if the marking cover 1 is prepared. Easy to do. Other operational effects are the same as those of the above-described sign cover 1 of the present embodiment, and are therefore omitted.
