Description

本発明は、道路反射鏡や交通標識等の道路用表示板を支柱などの支持体に固定させる取付構造に関するものである。   The present invention relates to a mounting structure for fixing a road display board such as a road reflector or a traffic sign to a support such as a support column.

従来、道路脇に設置される道路反射鏡や交通標識等の道路用表示板は、取付金具を介して支柱等に固定される構造が一般的であるが、大型車両などがこれに接触したときに、道路用表示板が破壊されたり、表示面の向きがずれるなどしてその機能が失われる場合があり、その対策について種々の提案がなされている。   Conventionally, road display boards such as road reflectors and traffic signs installed on the side of roads are generally fixed to support posts via mounting brackets, but when large vehicles come into contact with this In addition, the function may be lost due to the destruction of the road display board or the orientation of the display surface, and various proposals have been made for countermeasures.

例えば特許文献１には、運転席から直接見えない情景を反射させて運転の安定性を高める鏡２を交差点・曲がり部分等の道路傍に立設した支柱１に取り付ける如く構成した鏡２の支柱１への取付部材４であって、鏡２に結合する第一の結合部材４ａと支柱１に結合する第二の結合部材４ｂとを鉛直の硬質ゴム４ｃを介して結合してなる鏡２の支柱への取付部材を備えた道路用鏡支持装置、が開示されている。   For example, in Patent Document 1, a mirror 2 that is configured to attach a mirror 2 that reflects a scene that cannot be directly seen from a driver's seat and improves driving stability to a column 1 that stands up near a road such as an intersection or a curved portion. 1 is a mounting member 4 for connecting the mirror 2 with a first coupling member 4a coupled to the mirror 2 and a second coupling member 4b coupled to the support column 1 via a vertical hard rubber 4c. A mirror support device for a road provided with a member attached to a support is disclosed.

実開平２−０６６８１１号公報Japanese Utility Model Publication No. 2-066811

特許文献１に示される道路用鏡支持装置は、図面において第一の結合部材４ａ及び第二の結合部材４ｂと硬質ゴム４ｃとの結合をボルトで行うように示されているが、このような構成においては硬質ゴム４ｃの変形によってボルトの締結が緩みやすくなり、その支持力が失われて道路用鏡が外れてしまう恐れがあるという問題があった。   Although the mirror support device for roads shown by patent document 1 is shown in the drawing so that the 1st connecting member 4a and the 2nd connecting member 4b, and hard rubber 4c may be combined with a bolt, such a thing is shown. In the configuration, there is a problem that the fastening of the bolt is easily loosened due to the deformation of the hard rubber 4c, the supporting force is lost, and the road mirror may be detached.

そこで本発明は、車両などが接触しても表示板が破壊されにくく、継続的に支持可能な道路用表示板の取付構造を提供するものである。   Therefore, the present invention provides an attachment structure for a road display board that can be continuously supported, and the display board is not easily destroyed even when a vehicle or the like comes into contact.

上記目的を達成するため、本発明は以下のような構成としている。
すなわち本発明に係る道路用表示板の取付構造は、弾性材料からなる固定具を介して、表示板を備えた表示部材が支持体に固定される道路用表示板の取付構造であって、
前記固定具には少なくとも前記支持体又は前記表示部材のいずれかとの固定に用いられる締結部材が挿通する貫通穴が設けられ、
該貫通穴の内部には前記締結部材が締結される際の前記貫通穴の周縁部の変形を抑制させるスペーサーが内装されていることを特徴としている。 In order to achieve the above object, the present invention is configured as follows.
That is, the road display board mounting structure according to the present invention is a road display board mounting structure in which a display member provided with a display board is fixed to a support via a fixture made of an elastic material.
The fixing tool is provided with a through hole through which a fastening member used for fixing to at least the support or the display member is inserted,
A spacer that suppresses deformation of the peripheral portion of the through hole when the fastening member is fastened is provided inside the through hole.

本発明に係る道路用表示板の取付構造によれば、弾性材料からなる固定具を介して、表示板を備えた表示部材を支持体に固定させ、少なくとも前記支持体又は前記表示部材のいずれかとの固定に用いられる締結部材を挿通させる貫通穴を前記固定具に設け、この貫通穴の内部に前記締結部材を締結させる際の前記貫通穴の周縁部の変形を抑制させるスペーサーを内装させるので、前記締結部材を締結させたときに、前記スペーサーによって前記固定具の貫通穴周縁の変形が抑制され、適正な大きさの力で前記締結部材が締結されるので、道路用表示板に車両などが接触してもその締結が緩みにくくなされ、前記道路用表示板が継続的に支持される。   According to the road display board mounting structure according to the present invention, the display member provided with the display board is fixed to the support through the fixture made of an elastic material, and at least either of the support or the display member. Since a through hole through which a fastening member used for fixing is inserted is provided in the fixture, and a spacer that suppresses deformation of the peripheral portion of the through hole when the fastening member is fastened inside the through hole, When the fastening member is fastened, deformation of the peripheral edge of the through hole of the fixture is suppressed by the spacer, and the fastening member is fastened with an appropriate magnitude of force. Even if it contacts, the fastening is made difficult to loosen and the road display board is continuously supported.

また、前記固定具に、前記貫通穴を形成させた固定部と、表示部材に外力がかかったときに弾性変形する変形部とを形成させ、この変形部を前記固定部より薄肉に形成させれば、前記固定部よりも前記変形部がより変形しやすくなされるので、道路用表示板に車両などが接触したときに前記変形部が変形して受けた外力を緩和させ、前記固定部における変形を抑制させるので、前記締結部材の締結が緩みにくくなされ、前記道路用表示板が継続的に支持されるので、好ましい。   In addition, a fixing portion in which the through hole is formed and a deforming portion that is elastically deformed when an external force is applied to the display member are formed in the fixing tool, and the deforming portion is formed thinner than the fixing portion. For example, since the deformable portion is more easily deformed than the fixed portion, the external force received by deformation of the deformable portion when a vehicle or the like comes into contact with the road display board is reduced, and the deformable portion is deformed. Therefore, it is preferable that the fastening member is not easily loosened and the road display board is continuously supported.

また、前記固定具において、前記固定部側から前記変形部側へ至る程に肉厚が緩やかに薄くなる変厚部を、前記固定部と前記変形部との間に形成させれば、道路用表示板に車両などが接触して前記変形部が変形するときに、薄肉の変形部と前記固定部との肉厚が変化する境界部分への力の集中が前記変圧部で分散されて緩和されるので、前記固定具が破壊されにくくなされ、前記道路用表示板が継続的に支持されるので、好ましい。   Further, in the fixing device, if a thickness changing portion whose thickness gradually decreases from the fixing portion side to the deforming portion side is formed between the fixing portion and the deforming portion, When the vehicle or the like comes into contact with the display plate and the deformed portion is deformed, the concentration of force on the boundary portion where the thickness of the thin deformed portion and the fixed portion changes is dispersed and relaxed by the transformer portion. Therefore, the fixing tool is not easily broken, and the road display board is continuously supported, which is preferable.

また、前記固定具に、前記表示部材の後面側に当接させる当接面を全体に備えた板状の表示当接部と、この表示当接部から後方へ垂直に突出する板状の支持部を備えさせ、前記固定部と前記変形部とを前記支持部に形成させれば、道路用表示板に車両などが接触したときに、前記表示当接部における変形が当接面に当接された前記表示部材によって抑制され、前記表示当接部と前記表示部材との固定が外れにくくなされるので、好ましい。また、固定具の変形が前記支持部の前記変形部においてなされるので、前記固定部における変形が抑制され、前記締結部材と、好ましい。   In addition, a plate-like display abutting portion provided with an abutting surface to be brought into contact with the rear surface side of the display member on the fixture, and a plate-like support projecting vertically from the display abutting portion to the rear If the vehicle is in contact with the road display board, the deformation in the display contact portion contacts the contact surface. This is preferable because the display member is suppressed and the display contact portion and the display member are hardly fixed. Moreover, since the deformation | transformation of a fixing tool is made in the said deformation | transformation part of the said support part, the deformation | transformation in the said fixation part is suppressed and it is preferable with the said fastening member.

本発明に係る道路用表示板の取付構造によれば、車両などが接触しても表示板が破壊されにくく、継続的に表示板を支持できる。   According to the mounting structure of a road display board according to the present invention, the display board is not easily broken even when a vehicle or the like comes into contact, and the display board can be supported continuously.

Since the inner surface of the part and the inner surface of the nut 8b are in contact with the edge of the spacer 4, respectively, the deformation of the fixing part 36 to a thickness less than the length of the spacer 4 is suppressed. The bolts and nuts 8a and 8b are fastened with an appropriate torque so that they are not loosened, and the fixing is stably continued.

また、固定具３の支持部３５において、支柱バンド２１との固定に用いられるボルト８ａを挿通させる貫通穴３９を固定部３６に形成させ、この固定部３６と表示部材１を固定させた表示当接部３１との間に、固定部３６より若干薄肉の変形部３７を形成させることで、図２に示すように表示部材１が外力を受けて固定具３が変形するときに、主に変形部３７で変形がなされて固定部３６における変形が抑制されるので、ボルト・ナット８ａ、８ｂの締結が緩みにくいものとなされる。   Further, in the support portion 35 of the fixture 3, a through hole 39 through which the bolt 8 a used for fixing to the support band 21 is inserted is formed in the fixing portion 36, and the fixing portion 36 and the display member 1 are fixed. By forming a deformed portion 37 that is slightly thinner than the fixed portion 36 between the contact portion 31 and the display member 1 is subjected to an external force as shown in FIG. Since the deformation is performed at the portion 37 and the deformation at the fixing portion 36 is suppressed, the fastening of the bolts and nuts 8a and 8b is hardly loosened.

また、前記固定部３６と変形部３７との間に、前記固定部３６から前記変形部３７へ至る程に肉厚が緩やかに薄くなる変厚部３８を設けることで、図２に示すように表示部材１が外力を受けて固定具３が変形するときに、薄肉の変形部３７と前記固定部３６との肉厚が変化する境界部分へ力の集中せずに前記変圧部３８で分散されて緩和されるので、この部分における固定具３の破壊が抑制される。   Further, by providing a thickness changing portion 38 between the fixing portion 36 and the deforming portion 37, the thickness of which gradually decreases from the fixing portion 36 to the deforming portion 37, as shown in FIG. When the display member 1 receives an external force and the fixture 3 is deformed, the force is not concentrated on the boundary portion where the thickness of the thin deformed portion 37 and the fixed portion 36 changes, and is distributed by the transformer 38. Therefore, the breakage of the fixture 3 in this portion is suppressed.

また、前記固定具３の表示当接部３１に、全体的に平面な表示当接面３２を形成させて、表示部材１の突条１３ａ、１３ｂの縁に当接させるので、外力を受けて固定具３が変形するときに、表示当接部３１の変形が当接される突条１３ａ、１３ｂによって抑制されるので、ボルト・ナット８ａ、８ｂの締結が緩みにくくなされる。   Further, the display contact portion 31 of the fixture 3 is formed with a generally flat display contact surface 32 and is brought into contact with the edges of the protrusions 13a and 13b of the display member 1, so that an external force is received. When the fixture 3 is deformed, the deformation of the display contact portion 31 is suppressed by the projecting ridges 13a and 13b, so that the bolts and nuts 8a and 8b are not easily tightened.

本実施形態の道路用表示板の取付構造は、固定具３の形状が異なっていることが図６に示す実施形態との相違点である。
具体的には、本実施形態の固定具３は、断面がＬの字形状に形成されて設けられており、より詳細には板面を前方及び後方へ向けた長方形の板状の表示当接部３１と、この表示当接部３１の後面の水平方向端部分から後方へ突出する板形状の支持部３５とを備えるように形成させている。
そして、表示当接部３１の前面から後面に至る貫通穴３３を、表示当接部３１の中央付近に１個のみ形成させている点が、図６に示される実施形態の固定具３と異なる主な事項である。 FIG. 8 shows another embodiment of a fixture used in the mounting structure for a road display board according to the present invention, (A) is a plan view, (B) is a rear view, and (C) is a rear view. FIG. 9 is a side view, and FIG. 9 is a plan view showing an example of a state in which the fixture of FIG. 7 is attached to the display member.

And a plate-shaped support portion 35 that protrudes rearward from the horizontal end portion of the rear surface of the display contact portion 31.
6 differs from the fixture 3 of the embodiment shown in FIG. 6 in that only one through hole 33 extending from the front surface to the rear surface of the display contact portion 31 is formed near the center of the display contact portion 31. It is the main matter.

一方、本実施形態の固定具３の支持部３５の形状は、図６の形状と同様であり、即ち、表示当接部３１側に近い根本側に変形部３７を設け、突出する先側に変形部３７より若干厚肉の固定部３６を設け、変形部３７と固定部３６との間に変形部３７に至る程緩やかに薄肉となる変厚部３８を設けると共に、固定部３６に円形の貫通穴３９を上下方向に２個並設させて形成させている。   On the other hand, the shape of the support portion 35 of the fixture 3 of the present embodiment is the same as the shape of FIG. 6, that is, the deformable portion 37 is provided on the base side close to the display contact portion 31 side, and the protruding tip side is provided. A fixed portion 36 that is slightly thicker than the deformable portion 37 is provided, and a variable thickness portion 38 that gradually becomes thinner toward the deformable portion 37 is provided between the deformable portion 37 and the fixed portion 36, and the fixed portion 36 has a circular shape. Two through holes 39 are formed side by side in the vertical direction.

本実施形態の表示部材１、支柱２、支柱バンド２１の形状は、図１に示す実施形態と同一であり、支柱２に巻回させた支柱バンド２１の各バンド固定部２４ａ、２４ｂの各バンド貫通穴２５ａ、２５ｂにボルト８ａの雄ねじ部分を挿通させ、更に固定具３の支持部３５の各貫通穴３９に挿通させて、それぞれナット８ｂに螺結させることによって、前記支柱バンド２１が支柱２に固定されると共に、前記固定具３が前記支柱バンド２１に固定される。   The shape of the display member 1, the support 2, and the support band 21 of the present embodiment is the same as that of the embodiment shown in FIG. 1, and the bands of the band fixing portions 24 a and 24 b of the support band 21 wound around the support 2. The male screw portion of the bolt 8a is inserted into the through holes 25a and 25b, and further inserted into the through holes 39 of the support portion 35 of the fixture 3 and screwed into the nuts 8b. And the fixture 3 is fixed to the support band 21.

また、前記表示部材１の胴縁１２の各突条１３ａ、１３ｂ間に取り付けられたボルト９ａの雄ねじ部分を前記表示当接部３１の貫通穴３３に挿通させてナット９ｂを螺結させることによって、前記各突条１３ａ、１３ｂの突出縁部分に前記表示当接部３１の前面である表示当接面３２を当接させて、固定具３が表示部材１に固定される。   Further, by inserting the male screw portion of the bolt 9a attached between the protrusions 13a, 13b of the body edge 12 of the display member 1 into the through hole 33 of the display contact portion 31, and screwing the nut 9b. The fixing tool 3 is fixed to the display member 1 by bringing the display contact surface 32 which is the front surface of the display contact portion 31 into contact with the protruding edge portions of the protrusions 13a and 13b.

尚、本実施形態の固定具３の各貫通穴３３、３９には、図１の実施形態と同様に、あらかじめ図６に示される形態と同様のスペーサー４が内装されており、ボルト・ナット８ａ、８ｂ、及びボルトナット９ａ、９ｂの締結の際に、各貫通穴３３、３９の周縁部における固定具３の変形を抑制させて、これらの締結を緩みにくいものとしている。   The through holes 33 and 39 of the fixture 3 of the present embodiment are preliminarily provided with the same spacers 4 as those shown in FIG. 6 in the same manner as in the embodiment of FIG. 8b and the bolts and nuts 9a and 9b are fastened by suppressing deformation of the fixture 3 at the peripheral portions of the through holes 33 and 39 so that the fastening is difficult to loosen.

また、図１〜７の実施形態と同様に、固定具３の支持部３５において、支柱バンド２１との固定に用いられるボルト８ａを挿通させる貫通穴３９を固定部３６に形成させ、この固定部３６と表示部材１を固定させた表示当接部３１との間に、固定部３６より若干薄肉の変形部３７を形成させることで、表示部材１が外力を受けて固定具３が変形するときに、主に変形部３７で変形がなされて固定部３６における変形が抑制されるので、ボルト・ナット８ａ、８ｂの締結が緩みにくいものとなされる。   As in the embodiment of FIGS. 1 to 7, in the support portion 35 of the fixture 3, a through hole 39 through which a bolt 8 a used for fixing to the support band 21 is inserted is formed in the fixing portion 36. When the display member 1 is subjected to an external force and the fixture 3 is deformed by forming a deformed portion 37 that is slightly thinner than the fixed portion 36 between the display contact portion 31 that fixes the display member 1 and 36. In addition, since deformation is mainly performed at the deformation portion 37 and deformation at the fixing portion 36 is suppressed, the fastening of the bolts and nuts 8a and 8b is hardly loosened.

また、図１〜７の実施形態と同様に、前記固定部３６と変形部３７との間に、前記固定部３６から前記変形部３７へ至る程に肉厚が緩やかに薄くなる変厚部３８を設けることで、表示部材１が外力を受けて固定具３が変形するときに、薄肉の変形部３７と前記固定部３６との肉厚が変化する境界部分へ力の集中せずに前記変圧部３８で分散されて緩和されるので、この部分における固定具３の破壊が抑制される。   1-7, between the fixed portion 36 and the deformable portion 37, the variable thickness portion 38 whose thickness gradually decreases from the fixed portion 36 to the deformable portion 37. When the display member 1 receives an external force and the fixture 3 is deformed, the transformation is performed without concentrating the force on the boundary portion where the thickness of the thin deformed portion 37 and the fixed portion 36 changes. Since it is disperse | distributed and eased by the part 38, destruction of the fixing tool 3 in this part is suppressed.

また、図１〜７の実施形態と同様に、前記固定具３の表示当接部３１に、全体的に平面な表示当接面３２を形成させて、表示部材１の突条１３ａ、１３ｂの縁に当接させるので、外力を受けて固定具３が変形するときに、表示当接部３１の変形が当接される突条１３ａ、１３ｂによって抑制されるので、ボルト・ナット８ａ、８ｂの締結が緩みにくくなされる。   Moreover, like the embodiment of FIGS. 1 to 7, the display contact portion 31 of the fixture 3 is formed with a generally flat display contact surface 32, and the protrusions 13 a and 13 b of the display member 1 are formed. Since it is made to contact | abut to an edge, when the fixing tool 3 deform | transforms in response to an external force, since the deformation | transformation of the display contact part 31 is suppressed by the protrusion 13a, 13b to which it contact | abuts, Fastening is made difficult to loosen.

図１０は本発明にかかる道路用表示板の取付構造に用いる固定具の他の実施の一形態を示す、（イ）は平面図であり、（ロ）は背面図であり、（ハ）は側面図であり、図１１は図９の固定具を表示部材に取り付けた状態の一例を示す平面図である。
本実施形態の道路用表示板の取付構造は、固定具３の形状が異なることが図６、及び図８に示す実施形態との相違点である。
具体的には、本実施形態の固定具３は、中空部分を有し長手方向を上下へ向けて開口する筒体に形成されており、その形状は、前面が全体的に平面に形成され、その左右の両縁から後方へ側面が延設されると共に、各側面は後方へ至る程に中央方向へアールを描いて収束して後面に至り、更に後面の中央において筒壁の一部が前記筒体の内側方向へ突出して窪み長手方向に沿う溝を後面に形成させている。 FIG. 10 shows another embodiment of a fixture used in the mounting structure of a road display board according to the present invention. (A) is a plan view, (B) is a rear view, and (C) is a rear view. 11 is a side view, and FIG. 11 is a plan view showing an example of a state in which the fixture of FIG. 9 is attached to the display member.
The road display board mounting structure of this embodiment is different from the embodiment shown in FIGS. 6 and 8 in that the shape of the fixture 3 is different.
Specifically, the fixture 3 of the present embodiment is formed in a cylindrical body that has a hollow portion and opens in the longitudinal direction upward and downward, and the shape of the fixture 3 is formed entirely on a flat surface, Sides extend from the left and right edges to the rear, and each side draws a round toward the center as it reaches the rear, converges to the rear surface, and further, a part of the cylinder wall is at the center of the rear surface. A groove that protrudes inward of the cylindrical body and extends along the longitudinal direction of the depression is formed on the rear surface.

本実施形態の固定具３の形状をより詳細に説明すると、固定具３の前面は全体的に平面に形成されて表示当接面３２を構成し、その筒壁部分が表示当接部３１を構成している。
また前記筒壁は表示当接部３１の両側の縁から後方へ延設されて側面部分を形成させ、この側面部分が後方中央方向へ収束して後面部分を形成させているが、前記側面部分の表示当接部３１付近と前記後面中央付近とにおける筒壁の厚さに対して、その間の部分の筒壁を若干薄肉に形成させて変形部３７を形成するように設けている。
また、前記変形部３７と前記の各厚肉部分との間には、前記の厚肉部分の側から変形部３７の方へ至る程に緩やかに薄肉となる変厚部３８をそれぞれ形成させている。 The shape of the fixture 3 according to the present embodiment will be described in more detail. The front surface of the fixture 3 is entirely formed as a plane to form a display contact surface 32, and the cylindrical wall portion of the fixture 3 serves as the display contact portion 31. It is composed.
The cylindrical wall extends rearward from the edges on both sides of the display contact portion 31 to form a side surface portion, and the side surface portion converges toward the rear center to form a rear surface portion. With respect to the thickness of the cylindrical wall in the vicinity of the display abutting portion 31 and the vicinity of the center of the rear surface, the deformed portion 37 is formed by forming the cylindrical wall in a portion between them slightly thin.
Further, between the deformable portion 37 and each thick portion, a thickened portion 38 that gradually becomes thinner from the thick portion side toward the deformable portion 37 is formed. Yes.

そして、後面中央の筒壁の一部が筒体の内側へ突出し、上下方向に沿う溝を形成するように設けられた部分において、前記の内側へ突出する部分の側方の筒壁に、水平方向へ貫通する貫通穴３９を上下方向に並設させて２個形成させている。   Then, a part of the cylindrical wall at the center of the rear surface protrudes inward of the cylindrical body, and in a portion provided so as to form a groove along the vertical direction, the horizontal cylindrical wall on the side of the portion protruding inwardly is horizontal. Two through holes 39 penetrating in the direction are formed side by side in the vertical direction.

本実施形態の表示部材１、支柱２、支柱バンド２１の形状は、図１及び図９に示す実施形態と同一である。
支柱２に巻回させた支柱バンド２１の各バンド固定部２４ａ、２４ｂは、前記固定具３の後面に形成された前方に突出する溝部分に挿入される。
前記固定具３に形成された貫通穴３９は、支柱バンド２１のバンド貫通穴２５ａ、２５ｂに対応した大きさと配置に形成されており、ボルト８ａの雄ねじ部分を固定具３の中空部分から一方の貫通穴３９へ挿通させ、更に前記支柱バンド２１の各バンド固定部２４ａ、２４ｂに形成させた各バンド貫通穴２５ａ、２５ｂへそれぞれ貫通させ、最後に他方の貫通穴３９へ挿通させた後、ナット８ｂを螺結させ、固定具３を支柱バンド２１に固定させる。 The shapes of the display member 1, the support column 2, and the support band 21 of the present embodiment are the same as those of the embodiment shown in FIGS.
The band fixing portions 24 a and 24 b of the support band 21 wound around the support 2 are inserted into groove portions protruding forward and formed on the rear surface of the fixture 3.
The through hole 39 formed in the fixture 3 is formed in a size and an arrangement corresponding to the band through holes 25a and 25b of the support band 21, and the male screw portion of the bolt 8a is moved from the hollow portion of the fixture 3 to one side. After passing through the through hole 39 and further through the band through holes 25a and 25b formed in the band fixing portions 24a and 24b of the support band 21 and finally through the other through hole 39, the nut 8b is screwed to fix the fixture 3 to the support band 21.

また、固定具３の前方の表示当接部３１の筒壁部分には、筒壁の外側面から内側面に至る貫通穴３３を水平方向へ２個並設させて形成させており、前記表示部材１の胴縁１２の各突条１３ａ、１３ｂ間に取り付けられたボルト９ａの雄ねじ部分を前記表示当接部３１の貫通穴３３に挿通させてナットを螺結させることによって、前記各突条１３ａ、１３ｂの突出縁部分に前記表示当接部３１の前面である表示当接面３２を当接させて、固定具３が表示部材１に固定される。   Further, two through holes 33 extending from the outer side surface to the inner side surface of the cylindrical wall are formed side by side in the horizontal direction in the cylindrical wall portion of the display abutting portion 31 in front of the fixture 3. By inserting the male thread portion of the bolt 9a attached between the protrusions 13a, 13b of the body edge 12 of the member 1 into the through hole 33 of the display contact portion 31 and screwing the nut, The fixture 3 is fixed to the display member 1 by bringing the display contact surface 32, which is the front surface of the display contact portion 31, into contact with the protruding edge portions of 13 a and 13 b.

前記側面と後面の端付近の筒壁に対して、これより若干薄肉に形成された変形部３７を設けることで、表示部材１に外力を受けて固定具３が変形するときには、変形部３７においてより容易に変形がなされて他の部分での変形が抑制され、貫通穴３９に挿通されて固定されているボルト・ナット８ａ、８ｂの締結が緩みにくいものとなされる。   By providing a deformed portion 37 formed slightly thinner than the cylindrical wall near the end of the side surface and the rear surface, when the fixture 3 is deformed by receiving external force on the display member 1, The deformation is more easily performed, the deformation at other portions is suppressed, and the bolts and nuts 8a and 8b inserted and fixed through the through holes 39 are not easily loosened.

また、前記変形部３７と、これより厚肉に形成された筒壁部分との間に、前記の厚肉部分の側から変形部３７の方へ至る程に緩やかに薄肉となる変厚部３８が形成されることで、表示部材１が外力を受けて固定具３が変形するときに、薄肉の変形部３７と前記厚肉部分との境界部分へ力の集中せずに前記変厚部３８で分散されて緩和されるので、この部分における固定具３の破壊が抑制される。   In addition, a thickness change portion 38 that gradually becomes thinner between the deformation portion 37 and the cylindrical wall portion formed thicker from the thick portion side toward the deformation portion 37. Thus, when the display member 1 receives an external force and the fixture 3 is deformed, the thickness changing portion 38 is not concentrated on the boundary portion between the thin deformation portion 37 and the thick portion. Therefore, the breakage of the fixture 3 in this portion is suppressed.

また、本実施形態の固定具３の各貫通穴３３、３９には、図１〜７の実施形態、及び図８〜９の実施形態と同様に、あらかじめ図６に示される形態と同様のスペーサー４が内装されており、ボルト・ナット８ａ、８ｂ、及びボルトナット９ａ、９ｂの締結の際に、各貫通穴３３、３９の周縁部における固定具３の変形を抑制させて、これらの締結を緩みにくいものとしている。   Also, in each of the through holes 33 and 39 of the fixture 3 of the present embodiment, the same spacer as that shown in FIG. 6 in advance, as in the embodiment of FIGS. 1 to 7 and the embodiment of FIGS. 4 is installed, and when fastening the bolts / nuts 8a, 8b and the bolts / nuts 9a, 9b, the deformation of the fixture 3 at the peripheral portions of the through holes 33, 39 is suppressed, and these fastenings are performed. It is difficult to loosen.

また、図１〜７の実施形態、及び図８〜９の実施形態と同様に、前記固定具３の表示当接部３１の前面を、全体的に平面な表示当接面３２に形成させて、表示部材１の突条１３ａ、１３ｂの縁に当接させるので、外力を受けて固定具３が変形するときに、表示当接部３１の変形が当接される突条１３ａ、１３ｂによって抑制されるので、ボルト・ナット８ａ、８ｂの締結が緩みにくくなされる。   In addition, as in the embodiment of FIGS. 1 to 7 and the embodiment of FIGS. 8 to 9, the front surface of the display contact portion 31 of the fixture 3 is formed as a generally flat display contact surface 32. Since the abutment is made to abut against the edges of the protrusions 13a and 13b of the display member 1, the deformation of the display contact portion 31 is suppressed by the protrusions 13a and 13b abutted when the fixture 3 is deformed by receiving an external force. Therefore, the bolts and nuts 8a and 8b are not easily loosened.

本実施形態の固定具３は筒体に形成され、その中空部分の内部にボルト・ナット８ａ、８ｂを収納させて支柱バンド２１に固定されるので、表示部材１に外力を受けて固定具３が変形するときに、表示部材１の後面部分がボルト・ナット８ａ、８ｂに直接接触しないため、表示部材１の損傷が抑制される。
また、本実施形態の固定具３は、後面側に形成させた溝部分に、支柱バンド２１の各バンド固定部２４ａ、２４ｂの略全体を収納させるように設けられており、表示部材１に外力を受けて固定具３が変形するときに、表示部材１の後面部分がバンド固定部２４ａ、２４ｂに直接接触しないようになされ、表示部材１の損傷が抑制される。 The fixture 3 of the present embodiment is formed in a cylindrical body, and the bolts and nuts 8a and 8b are accommodated in the hollow portions and fixed to the support band 21. Therefore, the fixture 3 receives external force from the display member 1. Since the rear surface portion of the display member 1 does not directly contact the bolts and nuts 8a and 8b when the deformation of the display member 1, damage to the display member 1 is suppressed.
Further, the fixture 3 of the present embodiment is provided so that substantially the entire band fixing portions 24a and 24b of the support band 21 are accommodated in the groove portion formed on the rear surface side, and an external force is applied to the display member 1. Accordingly, when the fixture 3 is deformed, the rear surface portion of the display member 1 is prevented from directly contacting the band fixing portions 24a and 24b, and damage to the display member 1 is suppressed.

図１〜１１に示す実施形態の表示部材１には、交通標識を表示させた表示板１を設けているが、これに限るものではなく、表示板１を道路反射鏡に形成させてもよく、他の表示板１に形成させてもよい。   Although the display board 1 which displayed the traffic sign is provided in the display member 1 of embodiment shown in FIGS. 1-11, it is not restricted to this, You may form the display board 1 in a road reflector. Alternatively, another display panel 1 may be formed.

また、スペーサー４は、固定具３の貫通穴３３や貫通穴３９に内装されて、その両側の端部をそれぞれボルト・ナット８ａ、８ｂやボルトナット９ａ、９ｂ等の締結部材や、表示部材１の胴縁１２の各突条１３ａ、１３ｂや、支柱バンド２１のバンド固定部２４ａ、２４ｂ等に当接させ、前記締結部材の締結の際に各貫通穴３３、３９の内側からこれらを支持して、各貫通穴３３、３９周縁の固定具３の変形を抑制させるとともに、前記締結部材の締結が適正なトルクでなされるように形成されている。
このため、前記の実施形態のスペーサー４は図６に示すように円筒形状に形成されているが、貫通穴に内装されてその両端に当接する各部材を前記貫通穴の内側から支持できる形状であれば円筒形状に限るものではなく、一例としては円筒形状の筒壁の一部に切り欠きを有する断面形状がＣの字形状に形成された略筒形状に形成させてもよい。
また、断面が円形以外の筒形状や略筒形状に形成させてもよい。この場合には、固定具３に形成させる貫通穴３３や貫通穴３９の形状を、スペーサー４の外形に対応した形状に形成させることで、内装させたスペーサー４が外部からの振動や外力によって貫通穴３３、３９の内部で揺動することが抑制され、固定具３やスペーサー４が破壊されにくくなされる。
また、スペーサー４の一方又は両方の筒壁の端部から垂直に延設される鍔部を設けることで、固定具３の固定においてスペーサー４と接触するボルト・ナット８ａ、８ｂやボルト・ナット９ａ、９ｂ、支柱バンド２１の支柱固定部２４ａ、２４ｂ、や胴縁１２の胴縁１３ａ、１３ｂ等とスペーサー４との接触面積が増加し、より安定して貫通穴３３、３９の周縁の固定具３の変形を抑制させることができる。この場合においても、貫通穴３３、３９の内部に前記鍔部を収納できる形状に貫通穴３３、３９を形成させて、内装させたスペーサー４の貫通穴３３、３９内部での揺動を抑制させるのが、好ましい。
スペーサー４は、前記のような形状に形成させることができるが、図６に示すような円筒形状に形成させることで、円形に形成させた貫通穴に内装させることができるので、スペーサー４や各貫通穴の形成が容易にできると共に、固定具３が変形するような外力がかかった際に、スペーサー４と、その中空部分に挿通させたボルト８ａやボルト９ａとの間に力がかかっても、スペーサー４の筒壁に力が集中するような角部分が形成されていないので、スペーサー４の耐久性が良好なものとなされ、好ましい。 The spacer 4 is housed in the through hole 33 and the through hole 39 of the fixture 3, and the end portions on both sides thereof are fastening members such as bolts / nuts 8 a and 8 b and bolt nuts 9 a and 9 b, and the display member 1. Are brought into contact with the protrusions 13a and 13b of the body rim 12 and the band fixing portions 24a and 24b of the support band 21 and supported from the inside of the through holes 33 and 39 when the fastening member is fastened. In addition, the deformation of the fixing tool 3 around the through holes 33 and 39 is suppressed, and the fastening member is fastened with an appropriate torque.
For this reason, the spacer 4 of the above embodiment is formed in a cylindrical shape as shown in FIG. 6, but in a shape that can support each member that is housed in the through hole and contacts both ends from the inside of the through hole. If it exists, it will not be restricted to a cylindrical shape, For example, you may make it form in the substantially cylindrical shape by which the cross-sectional shape which has a notch in a part of cylindrical cylindrical wall was formed in the C-shape.
Further, the cross section may be formed in a cylindrical shape or a substantially cylindrical shape other than circular. In this case, the shape of the through hole 33 and the through hole 39 formed in the fixture 3 is formed in a shape corresponding to the outer shape of the spacer 4 so that the internally mounted spacer 4 is penetrated by external vibration or external force. Oscillation within the holes 33 and 39 is suppressed, and the fixture 3 and the spacer 4 are not easily broken.
Further, by providing a flange extending vertically from the end of one or both cylindrical walls of the spacer 4, bolts / nuts 8a, 8b and bolts / nuts 9a that come into contact with the spacer 4 when the fixture 3 is fixed. 9b, the column fixing parts 24a and 24b of the column band 21, the contact areas between the body edges 13a and 13b of the body edge 12 and the spacer 4 and the spacers 4 are more stably fixed to the periphery of the through holes 33 and 39. 3 deformation can be suppressed. Even in this case, the through holes 33 and 39 are formed in the through holes 33 and 39 in such a shape that the collar portion can be accommodated, and the swinging of the interior spacer 4 in the through holes 33 and 39 is suppressed. Is preferred.
The spacer 4 can be formed in the shape as described above, but by forming it in a cylindrical shape as shown in FIG. Even if a through hole can be easily formed and an external force that deforms the fixture 3 is applied, even if a force is applied between the spacer 4 and the bolt 8a or the bolt 9a inserted through the hollow portion. Since the corner portion where the force concentrates on the cylindrical wall of the spacer 4 is not formed, the durability of the spacer 4 is improved, which is preferable.
