前記柱部は前記ベース部と一体成形されて形成されており、
前記柱部の外側面と前記ベース部の外側上面とが接続する外側接続部と、前記柱部の内側面と前記ベース部の内側上面とが接続する内側接続部とが、前記柱部の全周に亘ってそれぞれ形成され、
前記外側接続部は上方から下方へ至るほど浅い傾斜となされて外側へ向かう曲面状の傾斜面に形成されると共に、
前記内側接続部は上方から下方へ至るほど浅い傾斜となされて内側へ向かう曲面状の傾斜面に形成されていることを特徴とするものである。 In order to achieve the above object, the present invention is configured as follows.
That is, the marker column according to the present invention is a marker column including a base portion and a cylindrical column portion protruding upward from the base portion,
The column portion has flexibility to bend and restore elastically by contact with a vehicle,
The column part is formed integrally with the base part,
An outer connection portion that connects the outer surface of the column portion and the outer upper surface of the base portion, and an inner connection portion that connects the inner surface of the column portion and the inner upper surface of the base portion are all of the column portion. Formed over the circumference,
The outer connecting portion is formed as a curved inclined surface that is shallower from the upper side to the lower side and goes outward,
The inner connection portion is formed in a curved inclined surface that is shallower from the upper side to the lower side and is curved inward.

本発明に係る標識柱によれば、ベース部と、このベース部から上方へ突出させる円筒状の柱部とを備え、車両の接触などによって弾性的に曲がり復元する可撓性を前記柱部が備えるので、車両の接触による破損が抑制される
また、前記柱部を前記ベース部と一体成形して形成するので、前記柱部が前記ベース部から外れるような破損が生じにくくなされる。
また、前記柱部の外側面と前記ベース部の外側上面とを接続させる外側接続部と、前記柱部の内側面と前記ベース部の内側上面とを接続させる内側接続部とをそれぞれ形成させ、上方から下方へ至るほど浅い傾斜となって外側へ向かう曲面状の傾斜面に前記外側接続部を形成させると共に、上方から下方へ至るほど浅い傾斜となって内側へ向かう曲面状の傾斜面に前記内側接続部を形成させるので、前記柱部が弾性的に曲がる変形が生じたときに、前記外側接続部や前記内側接続部への力の集中が抑制され、破損しにくくなされる。
また、曲面状の傾斜面に形成された前記外側接続部と、内側接続部とを、前記柱部の全周に亘ってそれぞれ形成させるので、前記柱部が弾性的に曲がる変形が生じたときに、前記外側接続部や内側接続部へ加わる力が一箇所へ集中しにくくなされ、破損しにくくなされる。 According to the marker pillar according to the present invention, the pillar part includes a base part and a cylindrical pillar part protruding upward from the base part, and the pillar part has flexibility to bend and restore elastically by contact with a vehicle or the like. Since it is provided, damage due to contact with the vehicle is suppressed, and the pillar part is formed integrally with the base part, so that damage such that the pillar part is detached from the base part is less likely to occur.
In addition, an outer connection portion that connects the outer side surface of the column portion and the outer upper surface of the base portion, and an inner connection portion that connects the inner side surface of the column portion and the inner upper surface of the base portion are formed, respectively. The outer connecting portion is formed on a curved inclined surface that becomes shallower from the upper side to the lower side and goes outward, and the curved inclined surface that goes to the inner side becomes shallower from the upper side to the lower side. Since the inner connection portion is formed, the concentration of force on the outer connection portion and the inner connection portion is suppressed and the breakage is less likely to occur when the column portion is deformed to bend elastically.

また、前記突出部の上端を前記外側接続部の下端よりも下方に位置させるように形成すれば、前記柱部が車両の車輪に踏みつぶされる等して変形したときに、前記柱部の筒壁が前記突出部の上端と前記車輪との間に挟み込まれて破断するような破損が抑制されるので、好ましい。 In addition, if the inner connecting portion is formed below the outer connecting portion, when the column portion is deformed to bend elastically, the force concentrated on the base of the column portion is reduced to the inner portion of the column portion. And the outer portion are distributed at different height positions, which is preferable because breakage in the inner connection portion and the outer connection portion is suppressed.
In addition, when a protruding portion that protrudes upward from the inner upper surface of the base portion is formed inside the inner connecting portion, and the upper end of the protruding portion is positioned above the lower end of the inner connecting portion, When the column part is deformed to bend elastically, the inner side surface of the column part is brought into contact with the upper end of the projecting part and the deformation of the inner connection part is suppressed, so that the damage in the inner connection part is suppressed. And preferred.
In addition, if the upper end of the protruding portion is formed to be positioned below the lower end of the outer connecting portion, the cylinder of the column portion can be formed when the column portion is deformed by being crushed by a vehicle wheel. It is preferable because the wall can be prevented from being broken by being sandwiched between the upper end of the protruding portion and the wheel.

また、前記突出部を円形に突出させて形成させ、前記突出部と前記内側接続部との間隔を前記突出部の全周に亘って同じ大きさに設ければ、前記柱部が弾性的に曲がり柱部の内側面が前記突出部に当接したときに、前記柱部の前記突出部へ接触する部位が偏りにくくなされるので、前記突出部への接触による前記柱部の破損が抑制され、好ましい。 Further, if the projecting portion is formed to project in a circular shape, and the spacing between the projecting portion and the inner connecting portion is set to the same size over the entire circumference of the projecting portion, the column portion is elastically formed. When the inner side surface of the bent column portion abuts against the protruding portion, the portion of the column portion that contacts the protruding portion is less likely to be biased, so that damage to the column portion due to contact with the protruding portion is suppressed. ,preferable.

本発明に係る標識柱によれば、変形による柱部の根本への力の集中が抑制されて、破損しにくくなされ、耐久性が向上する。 According to the marker column according to the present invention, the concentration of force on the base of the column part due to deformation is suppressed, and it is difficult to break, and durability is improved.

Similarly to the step portion 46b, the step portion 46a includes a protrusion portion 47a protruding outward and an inclined surface portion 48a extending inward and downward from the outer edge of the protrusion portion 47a. The protrusion 47a constituting the upper surface of 46a has its surface direction directed vertically upward.
The protruding portion 47a of the stepped portion 46a is formed in the same shape as the protruding portion 47b of the stepped portion 46b, and is formed so as to protrude to the outside in the same size. The outer diameters of the projecting portion 47a and the projecting portion 47b are formed to a size corresponding to the inner diameter of the column portion 2, and project when the cylindrical portion 45 of the cap 4 is inserted into the column portion 2. The outer edges of the portions 47 a and 47 b are provided so as to be in pressure contact with the inner surface of the column portion 2.

また、前記段部４６ａの傾斜面部４８ａは、段部４６ｂの傾斜面部４８ｂと比較して、より下方向へ向かう傾斜面状に形成させている。即ち、前記段部４６ａの上下方向の大きさを前記段部４６ｂよりも大きく形成させている。
このように前記段部４６ａを形成することで、柱部２へキャップ４の筒部４５を挿入させるときに、前記各段部４６ａを形成させたキャップ４の筒部４５の下部を、柱部２の内側へより挿入しやすくなるように設けている。
また、上下方向の大きさをより小さく設けた前記段部４６ｂを筒部４５の上部へ形成させることで、筒部４５の上端まで柱部２の内側へ挿入させた状態で、キャップ４が柱部２へより強固に取り付けられるように設けている。
尚、本実施形態のキャップ４は、各段部４６ａ、４６ｂが形成された筒部４５の外側面に接着剤を塗布させ、柱部２へ接着固定させている。 Further, the inclined surface portion 48a of the stepped portion 46a is formed in a shape of an inclined surface that extends further downward as compared with the inclined surface portion 48b of the stepped portion 46b. That is, the size of the step 46a in the vertical direction is made larger than that of the step 46b.
By forming the step portion 46a in this way, when the cylindrical portion 45 of the cap 4 is inserted into the column portion 2, the lower portion of the cylindrical portion 45 of the cap 4 in which each step portion 46a is formed is replaced with the column portion. 2 is provided so that it can be easily inserted into the inside of 2.
Further, the stepped portion 46b having a smaller vertical size is formed on the upper portion of the cylindrical portion 45, so that the cap 4 is inserted into the column portion 2 up to the upper end of the cylindrical portion 45. It is provided so as to be attached to the part 2 more firmly.
In the cap 4 of this embodiment, an adhesive is applied to the outer surface of the cylindrical portion 45 in which the step portions 46a and 46b are formed, and is fixed to the column portion 2 by adhesion.

本実施形態の柱部２は、その下部における筒壁の厚さを上部より大きく形成させて、柱部２が折れ曲がった後に、元の状態へ復元しやすくなるように設けている。
具体的には、前記柱部２はその外側面の外径を一定の大きさに形成させ、その上下方向の中程に内径変化部２８を設けている。
この内径変化部２８より上方の柱上部２６においては、その内径を一定の大きさに設けて、筒壁の厚さを一定の大きさに形成させている。
また、前記内径変化部２８より下方の柱下部２７においては、その内径を下方に至るほど小径に設け、上方から下方へ至るほど筒壁の厚さが大きくなるように形成させている。
尚、前記柱下部２７の上端における筒壁の厚さは、前記柱上部２６の筒壁と同じ大きさである。 The column part 2 of the present embodiment is formed so that the thickness of the cylindrical wall at the lower part is formed larger than the upper part so that it can be easily restored to the original state after the column part 2 is bent.
Specifically, the column part 2 has an outer diameter of the outer side formed in a constant size, and an inner diameter changing part 28 is provided in the middle in the vertical direction.
In the column upper portion 26 above the inner diameter changing portion 28, the inner diameter thereof is provided with a constant size, and the thickness of the cylindrical wall is formed with a constant size.
Further, in the column lower portion 27 below the inner diameter changing portion 28, the inner diameter is formed so as to be smaller as it goes downward, and the thickness of the cylinder wall is increased as it goes from upper to lower.
Note that the thickness of the cylindrical wall at the upper end of the column lower portion 27 is the same as that of the cylindrical wall of the column upper portion 26.

上方から下方へ至るほど筒壁の厚さが大きくなるように前記柱下部２７を設けることで、前記柱部２が折れ曲がるように変形した後、元の状態へ復元しやすくなる。
また、内径を一定の大きさに設けた前記柱上部２６を柱部２の上部に形成することで、柱部２を切断したときでも、前記キャップ４を容易に取り付けできるように設けている。即ち、標識柱１の高さを調整するために前記柱部２の上端を切断する場合に、前記キャップ４の筒部４５が挿入可能な大きさの柱上部２６を残して柱部２を切断することで、内径が一定となされた柱上部２６へ前記筒部４５を容易に挿入することができるので、柱部２の長さを容易に調整できる。 By providing the column lower portion 27 so that the thickness of the cylindrical wall increases from the upper side to the lower side, the column portion 2 is easily deformed so as to be bent and then restored to the original state.
In addition, by forming the column upper portion 26 having an inner diameter of a certain size on the upper portion of the column portion 2, the cap 4 can be easily attached even when the column portion 2 is cut. That is, when the upper end of the column part 2 is cut in order to adjust the height of the marker column 1, the column part 2 is cut while leaving the column upper part 26 of a size that allows the cylindrical part 45 of the cap 4 to be inserted. By doing so, since the said cylinder part 45 can be easily inserted in the pillar upper part 26 by which the internal diameter was made constant, the length of the pillar part 2 can be adjusted easily.

尚、本実施形態の柱部２は、その上端からベース部３の下面までの大きさを８０ｃｍに形成させ、前記内径変化部２８からベース部３の下面までの大きさを５０ｃｍに形成させており、内径変化部２８から柱部２の上端までの前記柱上部２６を３０ｃｍの大きさに形成させている。
また、前記キャップ４は、筒部２５の上下方向の大きさを１０ｃｍに形成させており、前記柱上部２６を２０ｃｍ切断させた場合でも、前記キャップ４を前記柱部２へ容易に取り付けることができるように設けている。
本実施形態の柱部２及びベース部３は射出成形により一体に形成させているので、筒壁を一定の大きさに設ける前記柱上部２６や、下方に至るほど厚壁に設ける前記柱下部２７を柱部２に容易に形成させることができる。 The column part 2 of this embodiment is formed such that the size from the upper end to the lower surface of the base part 3 is 80 cm, and the size from the inner diameter changing part 28 to the lower surface of the base part 3 is 50 cm. The column upper portion 26 from the inner diameter changing portion 28 to the upper end of the column portion 2 is formed in a size of 30 cm.
In addition, the cap 4 is formed so that the vertical size of the cylindrical portion 25 is 10 cm, and the cap 4 can be easily attached to the column portion 2 even when the column upper portion 26 is cut by 20 cm. It is provided as possible.
Since the column portion 2 and the base portion 3 of this embodiment are integrally formed by injection molding, the column upper portion 26 provided with a cylindrical wall with a certain size, and the column lower portion 27 provided with a thick wall toward the bottom. Can be easily formed on the pillar portion 2.

図６は図１の標識柱１の柱部２が弾性的に曲がるように変形した状況を示すベース部３付近の断面図である。
図６は、柱部２の図中左側に位置する筒壁２ａをベース部３の中心方向、即ち図中右方向へ緩く曲げた状況を示している。
図６のように柱部２を曲げ変形させたとき、柱部２とベース部３には、それぞれを伸張させる力と圧縮させる力とが加えられる。
具体的には、柱部２の筒壁２ａをベース部３の中心方向へ曲げたとき、筒壁２ａの外側面２２と、この外側面２２に接続する外側接続部２４と、この外側接続部２４に接続する前記ベース部３の外側上面３２とには、これらを伸張させる方向へ力が加えられ、この力は主に柱部２の根本である外側接続部２４付近に集中する。 FIG. 6 is a cross-sectional view of the vicinity of the base portion 3 showing a state in which the column portion 2 of the marker column 1 in FIG. 1 is deformed so as to bend elastically.
FIG. 6 shows a situation where the cylindrical wall 2a located on the left side of the column part 2 in the drawing is loosely bent toward the center of the base 3, that is, to the right in the drawing.
When the column part 2 is bent and deformed as shown in FIG. 6, a force for expanding and compressing each of the column part 2 and the base part 3 are applied.
Specifically, when the cylindrical wall 2a of the column portion 2 is bent toward the center of the base portion 3, the outer surface 22 of the cylindrical wall 2a, the outer connecting portion 24 connected to the outer surface 22, and the outer connecting portion. A force is applied to the outer upper surface 32 of the base portion 3 connected to 24 in the direction in which they are extended, and this force is concentrated mainly in the vicinity of the outer connection portion 24 that is the root of the column portion 2.

また、柱部２の筒壁２ａをベース部３の中心方向へ曲げたとき、筒壁２ａの内側面２３と、この内側面２３に接続する内側接続部２５と、この内側接続部２５に接続する前記ベース部３の内側上面３３とには、これらを圧縮させる方向へ力が加えられる。本実施形態のベース部３は、前記内側接続部２５と内側上面３３とを、それぞれ外側接続部２４とベース部３の外側上面３２よりも下方に形成させることで、前記筒壁２ａの内側面２３を圧縮させる力を前記外側接続部２４付近の筒壁２ａの内側面２３ａへ集中させずに、前記外側接続部２４よりも下方の内側接続部２５や内側上面３３へ分散させている。即ち、前記伸張させる力が集中する位置と、前記圧縮させる力が集中する位置の高さを異ならせており、筒壁２ａの破損を抑制させている。 Further, when the cylindrical wall 2a of the column part 2 is bent toward the center of the base part 3, the inner side surface 23 of the cylindrical wall 2a, the inner connection part 25 connected to the inner side surface 23, and the inner connection part 25 are connected. A force is applied to the inner upper surface 33 of the base portion 3 to compress them. In the base portion 3 of the present embodiment, the inner connecting portion 25 and the inner upper surface 33 are formed below the outer connecting portion 24 and the outer upper surface 32 of the base portion 3, respectively, so that the inner surface of the cylindrical wall 2a is formed. The force for compressing 23 is not concentrated on the inner surface 23 a of the cylindrical wall 2 a in the vicinity of the outer connecting portion 24, but is distributed to the inner connecting portion 25 and the inner upper surface 33 below the outer connecting portion 24. That is, the height of the position where the expanding force is concentrated and the position where the compressing force is concentrated are made different from each other, and the breakage of the cylindrical wall 2a is suppressed.

図７は図６の標識柱１の柱部２が更に曲がるように変形した状況を示す断面図である。
図７は、図６の筒壁２ａの内側面２３をベース部３の突出部３５へ当接するまで曲げた状況を示している。
本実施形態のベース部３は、内側上面３３から上方へ突出させて突出部３５を形成させることで、柱部２の筒壁２ａの折れ曲がる角度をより緩やかにして、筒壁２ａへの力の集中を緩和させ、その破損を抑制させている。
特に突出部３５を形成させることで、柱部２の内側における、筒壁２ａの内側面２３と、これに接続する内側接続部２５と、内側上面３３とが曲がる角度が緩和され、これらを圧縮させる力が低減される。 FIG. 7 is a cross-sectional view showing a state in which the column portion 2 of the marker column 1 of FIG. 6 is deformed so as to be further bent.
FIG. 7 shows a state where the inner side surface 23 of the cylindrical wall 2a of FIG. 6 is bent until it abuts against the protruding portion 35 of the base portion 3.
The base portion 3 of the present embodiment protrudes upward from the inner upper surface 33 to form a protruding portion 35, thereby making the bending angle of the cylindrical wall 2a of the column portion 2 more gentle, and the force to the cylindrical wall 2a. It eases concentration and suppresses breakage.
In particular, by forming the projecting portion 35, the angle at which the inner side surface 23 of the cylindrical wall 2a, the inner connecting portion 25 connected to the inner side surface 23, and the inner upper surface 33 are bent inside the column portion 2 is relaxed and compressed. The force to be reduced is reduced.

また、本実施形態のベース部３は、円柱状に形成させた突出部３５の上面と周側面とが接続される角部３５ａを全周に亘って角丸状に形成させているので、折れ曲がった筒壁２ａの内側面２３が前記角部３５ａへ接触したときに、内側面２３の損傷を抑制できる。
また、前記突出部３５をベース部３および柱部２と同心円状に配置させているので、突出部３５と柱部２との間隔が全周に亘って等しくなされる。このため、柱部２の筒壁２ａの内側面２３が前記突出部３５に接触するときに、前記突出部３５へ接触する部位が偏りにくくなされるので、前記突出部３５への接触による内側面２３の損傷の位置が周方向へ分散され、前記柱部２の破損が抑制される Moreover, since the base part 3 of this embodiment forms the corner | angular part 35a to which the upper surface and peripheral side surface of the protrusion part 35 formed in the column shape are connected rounded over the perimeter, it bends. When the inner side surface 23 of the cylindrical wall 2a contacts the corner portion 35a, damage to the inner side surface 23 can be suppressed.
Moreover, since the said protrusion part 35 is arrange | positioned concentrically with the base part 3 and the pillar part 2, the space | interval of the protrusion part 35 and the pillar part 2 is made equal over a perimeter. For this reason, when the inner side surface 23 of the cylindrical wall 2a of the column part 2 contacts the protruding portion 35, the portion that contacts the protruding portion 35 is less likely to be biased. The positions of the damage 23 are distributed in the circumferential direction, and the damage of the pillar portion 2 is suppressed.

また、本実施形態のベース部３は、前記突出部３５の上面の高さを前記外側上面３２よりも下方に位置させて形成させている。これは、柱部２が車両の車輪に踏みつぶされて図７のように曲げられたときに、前記突出部３５と前記車輪との間に前記筒壁２ａが挟み込まれるような状態となされるが、前記突出部３５と前記車輪から前記筒壁２ａへ加えられる力が、前記突出部３５の上面の高さを前記外側上面３２よりも上方に位置させた場合と比較して低減されるので、前記筒壁２ａの破損が抑制される。 Further, the base portion 3 of the present embodiment is formed such that the height of the upper surface of the protruding portion 35 is positioned below the outer upper surface 32. This is such that the cylindrical wall 2a is sandwiched between the protruding portion 35 and the wheel when the column portion 2 is crushed by a vehicle wheel and bent as shown in FIG. However, the force applied to the cylindrical wall 2a from the protrusion 35 and the wheel is reduced compared to the case where the height of the upper surface of the protrusion 35 is positioned above the outer upper surface 32. The damage to the cylindrical wall 2a is suppressed.
