Description

The present invention provides a display plate with information such as an identification number and application, in particular, a marking pile for displaying a land or road boundary or a buried position of a cable, a water pipe, a gas pipe or the like, or a boundary point display. The present invention relates to a display plate that can be easily and reliably attached to the surface of a product.

Conventionally, a plastic marking pile is used as a position display member when conducting a land ownership survey or the like. The marking pile has a colored cap attached to the head of a long and narrow bar-shaped pile body, and is driven into the ground so that the cap is exposed from the ground. Recently, in order to conduct a cadastral survey smoothly, a sign pile with an aluminum display plate attached with information such as identification number and usage is attached to the cap of the head of the sign pile that has been driven into the ground. Is attracting attention. As a method of fixing the display cap to this marking pile, place the display plate in the recess provided on the top surface of the marking pile cap driven into the ground, and (1) Insert the nail into the center of the display cap with a hammer. A method of fixing by driving into the head of the marking pile from the hole. (2) A method of fixing the display plate by matching the insertion hole of the display plate with the insertion hole of the cap, and manually pushing a fastening member having a screw-like locking portion into the insertion hole. Etc. have been proposed.

Also, in urban areas where the marking piles cannot be driven, a rectangular metal boundary point display product with a recess on the surface is affixed to concrete or asphalt, or fixed with anchor bolts, and a display plate is placed in the recess Then, a method of fixing the display plate by inserting a pin into the insertion hole of the display plate and striking it with a hammer and caulking the pin to a metal plate has been proposed.

The method of fixing the display plate with the nail has an advantage that the display plate can be securely fixed to the cap. However, it is necessary to always carry a heavy hammer, and when the nail is driven, the hammer is accidentally hit against the display plate, and information attached thereto may be damaged, or the hand on the side supporting the nail may be hit. The method of using a hammer to squeeze the pin and fix the pin tip to the metal plate is uneasy about staking the pin tip into a solid plate. is there.

On the other hand, the method of fixing the display plate by pushing the fixing member by hand has the advantage of not using a hammer, but in order to securely fix the display plate, locking that prevents the fixing member from being detached from the insertion hole of the cap. It is necessary to provide the portion on the inner wall of the insertion hole or the outer wall of the fastening member. However, providing a locking portion on the outer wall of the fastening member or the inner wall of the cap insertion hole complicates the mold, which increases the cost of the fastening member and the cap, which is not preferable.

As a result of a thorough examination of the problems of the conventional display plate and its fixing method, the present inventors have found that both of the conventional methods include two parts: a display plate and display plate fixing means (nails, fastening members, etc.). It is absolutely necessary to reach the conclusion that the above-mentioned problems will occur naturally, and the two parts of the display plate and the display plate fixing means are integrated into one part, and it can be easily pushed by hand. As a result of intensive studies to propose a display plate with a display plate fixing means that can be fixed, the present invention has been achieved.

That is, the display plate of the present invention is a cap that is crowned on the head of the marking pile, or a display plate that is fixed to a boundary point display product, and the display plate includes a flat head and the head A plurality of plate-like bodies that are bent vertically from the outer periphery and provided with a hook-like locking portion at the tip, and a recess or an opening is provided at the center of the head, The body is pushed into an insertion hole provided in a cap or a boundary point display product, and the locking portion is locked to the inner wall of the insertion hole.

Another display plate according to the present invention is a cap that is crowned on the head of the marking pile, or a display plate that fixes the display plate to a boundary point display product, the display plate including a flat head, Consists of a cone provided in the center of the head and a plurality of locking parts provided in the cone. The cone is inserted into an insertion hole provided in a cap or a boundary point display product, The stop portion is locked to the inner wall of the insertion hole.

Furthermore, another display plate of the present invention is a display plate fixed to a cap crowned on the head of the marking pile or a boundary point display product, the display plate including a flat head and the head A plurality of plate-like bodies bent vertically from the outer periphery and having a hook-like locking portion at the tip, a cone provided at the center of the head, and provided on the cone A plurality of locking portions, and the plate-like body and the cone are pushed into each insertion hole provided in the cap or the boundary point display product, and each locking portion is locked to the inner wall of the insertion hole. It is a feature.

When attaching the display plate of the present invention to a cap crowned on the head of a marking pile or a recess provided in a boundary point display product, first, a plate-like body and / or a cone provided on the display plate Is put into the insertion hole of the cap, and the head of the display plate is pressed with the thumb and pushed into the insertion hole. Finally, when the bent portion and / or the conical portion of the plate-like body are pressed, the locking portion biased outward in this state is engaged with the inner wall of the insertion hole. The body is securely locked in the insertion hole, and the separation from the insertion hole is prevented. Thus, the display plate can be easily and reliably fixed to the cap crowned on the head of the marking pile.

The display plate of the present invention can be easily manufactured by a conventional metal processing technique. For example, the display part plate described in claim 1 is formed by integrating the head of the display plate (a concave part provided at the center or an opening at the same time) and an elongated plate-like body from a metal plate having excellent corrosion resistance such as stainless steel. It can be easily manufactured by pressing and then bending the plate. The display plate described in claim 2 is formed by pressing a head and a cone after the metal plate is cut to form a locking portion in a cone provided at the center of the head of the display plate. . Finally, the cut portion provided in the cone is bent outward to form a locking portion.

According to the display plate of the present invention, the two parts of the display plate and the display plate fixing means are integrated into one part, and can be simply fixed by simply pushing the display plate or the boundary point display product by hand. The locking portion provided in the plate-like body and / or the conical body pushed into the insertion hole is biased outward and bites into the inner wall of the insertion hole, so that the display plate does not come off.

Hereinafter, an embodiment of a display plate according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the entire display plate A of the present invention. This display plate is composed of two elongated plate-like bodies 2 extending in the left-right symmetrical direction from the center of a flat plate-like head 1. It is bent vertically inward at the outer periphery a. Usually, the number of the plate-like body is two, but it may be increased in accordance with the size of the display plate (for example, three to four may be added. In order to push the plate-like body perpendicularly into the insertion hole, it is preferable that the tip end b is tapered to reduce the contact area with the inner wall of the insertion hole.
