Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to the improvement of lane marking devices used as road markings, and relates to a stud-type lane marking device that shows its shadow on the road surface.

(B) Conventional technology Conventional lane dividers used as road markings have a structure in which a marking part, such as a flat pyramid or a truncated pyramid, is installed protruding from the road surface by filling a buried protrusion drilled into the underside of the marking part. Therefore, the sign part always protrudes from the road surface.

(c) Problems that the invention aims to solve However, since the above structure has a structure that constantly protrudes from the road surface, it not only gets in the way during snow removal work, especially in snowy areas, but also interferes with the shovel of a snow removal vehicle. There is a problem in that both parts are damaged due to collision, and generally cannot be installed and used in snowy areas.

This invention was made in view of the above problems,
The purpose is to provide a stud-type lane divider that can be used even in snowy areas, and the marker part can be buried under the road surface during the snowy season, and can be exposed above the road surface during the non-snowy season. The purpose is to provide a sorter. A further object of the present invention is to provide a stud-type lane divider which is configured to reversibly store a stud-type lane divider buried in the roadbed, and which can easily and robustly perform the reversing operation.

(d) Means for solving the problem In order to achieve the above object, the stud-type lane divider of the present invention reversibly stores the stud-type lane division display block 7 in the buried tube 1 buried in the roadbed b. In the stud type lane divider, a support plate 5 having a similar shape to the cylinder hole 4 is placed inside the cylinder hole 4 at the upper end of the buried cylinder 1 buried in the roadbed b so as to be substantially flush with the road surface. It is semi-rotatably mounted via a center shaft 6 installed horizontally in the hole 4, and a stud-shaped lane division display block 7 in the shape of a flat cone or truncated cone is provided on one side of the support plate 5. A pair of locking members 1 extend from the buried cylinder 1 toward the lower surface of the support plate 5 so as to be firmly formed and to lock and fix the support plate 5 in the half-rotated position.
1 and 12 are elastically protruded, and one of the locking members 11 is made retractable from a position above the buried cylinder 1.

(E) Function In the stud-type lane divider mentioned above, since the support plate is rotatably pivoted to the buried cylinder, the position where the stud-type marking part is exposed relative to the upper end surface of the buried cylinder, and the corresponding It is possible to selectively lock the stud-shaped marker portion in the reversed and housed position.

That is, in the buried area where the stud-shaped sign part is exposed, the stud-shaped sign part forms a sign protruding from the road surface, and
When it is inverted and housed, the end surface of the buried cylinder is closed by the support plate, so there is no protruding structure from the road surface, and the road surface level is maintained.

When reversing the support plate, use a handy tool such as a crowbar from above to move the locking member backward in the outer diameter direction of the buried cylinder against its elasticity, and remove it from the lower surface of the support plate, so that it can be freely reversed, and Due to the elastic return of the locking member, the support plate is fixed again in the reversed position.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 indicates a cylindrical buried tube;
A bottom plate 2 having a diameter larger than the outer diameter of the buried cylinder 1 is welded and fixed to the lower end surface of the embedding cylinder 1, and a flange 2a for preventing removal is formed, and a plurality of drainage holes 3 are bored.

At the upper end of the buried cylinder 1, a disk-shaped support plate 5 which can be freely reversed in the cylinder hole 4 is pivotally installed via a center shaft 6 installed in the wall of the cylinder hole 4, and when in the inverted position. The wall surface is configured to be substantially flush with the cylinder end surface.

Further, a truncated flat cone-shaped stud-shaped lane marking block 7 is fixed and protruded from the upper surface of the support plate 5.

Reference numerals 8 and 9 denote protective members having a groove-like cross section and fixed in the vertical direction, facing each other at a position perpendicular to the center shaft 6 on the outer periphery of the buried cylinder 1; is equipped with locking members 11 and 12 made of elastic wire whose lower ends are fixed to the lower part of the buried cylinder 1 via bolts 10 and 10, respectively,
Locking ends 11a and 12a formed at the upper ends thereof respectively protrude into the cylinder through small holes 13 and 13 formed in the buried cylinder 1, and abut against both ends of the lower surface of the support plate 5. One of the locking members 11 has an engaging protrusion 11b projecting upwardly at its upper end, and
By inserting a handy device such as a crowbar a between the engagement protrusion 11b and the buried cylinder 1 (arrow A), the engagement protrusion 11b is moved in the outer radial direction (arrow B) against the elasticity of the engagement member 11. ) and can be removed from the bottom surface of the support plate 5.

Further, the locking end 12a of the other locking member 12 is formed with a tapered surface 12b on the lower surface, and the locking end 12a
The locking end 12a is moved in the external direction (arrow C) against the elasticity of the locking member 12 by the end of the support plate 5 that rotates in from the lower surface direction, and is caused to pass through the edge of the support plate 5. , after passing through, it will be located on the lower surface of the support plate 5 again due to elastic recovery.

The stud-type lane divider having the above configuration is used by being buried in the roadbed so that the upper end of the buried tube 1 is flush with the road surface b, and the collar portion 2a prevents extraction. Both protection members 8 and 9 serve as resistance plates to prevent rotation of the buried cylinder 1.

When used as a lane divider under normal conditions, the support plate 5 is placed so that the side with the stud-shaped lane divider block 7 is located on the top surface.
is the center shaft 6 and the two locking ends 11a, 1
2a, and even if a vehicle or the like runs onto the stud-shaped lane block 7, it will not be reversed.

In addition, when storing the stud-shaped lane block 7 during snowy conditions, etc., insert a handy tool such as a crowbar a between the engagement protrusion 11b and the buried tube 1 (arrow A), as shown in Fig. 3.
Then, by removing the locking end 11a from the lower edge of the support plate 5 and rotating it in the direction of arrow D, the locking end 11a is locked and fixed again in the inverted position (see FIG. 4).
At the upper end of the buried cylinder 1, a lower surface 5a of the support plate 5, which is flush with the road surface b, is exposed.

Therefore, during operations such as snow removal, the shovel of a snowplow vehicle will not come into contact with the sign, and it can be used inverted as a normal road marking during non-snowy seasons.

Incidentally, in the above embodiment, the buried cylinder 1 was explained as having a cylindrical shape, but depending on the planar shape of the stud-shaped lane block 7, it is possible to construct a cylindrical body with a cross section of various shapes such as square, rectangular, or elliptical. Needless to say.

(g) Effects of the invention As stated above, the stud-type lane divider of the present invention has the following effects:
Since the stud-shaped lane blocks can be housed under the road surface, there is no collision with snow removal vehicles during the snowy season, and the practical effects of implementing the present invention are extremely large.

In addition, in the present invention, the support plate of the stud-shaped lane block is semi-rotatably pivoted via the center shaft, so that the stud-shaped lane block can be stored under the road surface, and the supporting means after storage is simple and robust. Therefore, the reversing operation does not take much time and has good durability over time.
