前記本発明は、次のように作用する。
標識装置(10)は、車両に積載して工事指示や交通指示等の指標を表示するものである。
The present invention operates as follows.
The sign device (10) is mounted on a vehicle and displays indicators such as construction instructions and traffic instructions.

起倒体(30)の基部(31)が、車両上に装着されるベース(20)に枢支されて起倒可能であり、起倒体(30)の先端で標識部(40)が指標を表示する。   The base part (31) of the raising body (30) is pivotally supported by the base (20) mounted on the vehicle and can be raised and lowered, and the marker part (40) is an indicator at the tip of the raising body (30). Is displayed.

起倒体(30)とベース(20)との間に介装された電動油圧シリンダー(50)が伸縮すると、起倒体(30)が起倒し、それに伴って標識部(40)が昇降する。   When the electrohydraulic cylinder (50) interposed between the raising and lowering body (30) and the base (20) expands and contracts, the raising and lowering body (30) rises and the sign part (40) moves up and down accordingly. .

保持部材(41)とベース(20)との間に架設されたリンク部材(25)により構成された平行リンク機構により、起倒体(30)に枢支された標識部(40)の保持部材(41)が略水平な姿勢を保持して昇降し、標識部(40)は、略水平な姿勢を保持して、いずれの位置でも視認可能である。
すなわち、電動油圧シリンダー(50)の伸縮によりベース(20)が起倒し、標識部(40)が略水平な姿勢を保持したまま昇降する。
The holding member of the marker part (40) pivotally supported by the raising and lowering body (30) by the parallel link mechanism constituted by the link member (25) installed between the holding member (41) and the base (20). (41) moves up and down while maintaining a substantially horizontal posture, and the sign section (40) can be visually recognized at any position while maintaining a substantially horizontal posture.
That is, the base (20) is raised and lowered by the expansion and contraction of the electric hydraulic cylinder (50), and the sign portion (40) moves up and down while maintaining a substantially horizontal posture.

ベース(20)と起倒体(30)との間に介装されたガススプリング(60)はバランサーとして機能する。起倒体(30)が起立を始めたとき、ガススプリング(60)の基部の起倒リンク部材(61)は倒れていて、ガススプリング(60)の反力がベース(20)と起倒体(30)を離すように作用し、電動油圧シリンダー(50)の動力を補助する。   The gas spring (60) interposed between the base (20) and the raising body (30) functions as a balancer. When the raising body (30) starts to stand up, the raising / lowering link member (61) at the base of the gas spring (60) has fallen, and the reaction force of the gas spring (60) is reduced between the base (20) and the raising body. Acts to release (30) and assists the power of the electric hydraulic cylinder (50).

起倒体(30)が所定角度まで起立すると、起倒リンク部材(61)が起立してガススプリング(60)は伸び切った状態になり、その反力は起倒体(30)に伝達することがなくなる。   When the upright body (30) stands up to a predetermined angle, the upright link member (61) stands up and the gas spring (60) is fully extended, and the reaction force is transmitted to the upright body (30). Nothing will happen.

ロック機構(70)は倒伏時に起倒体(30)を保持して抑える。ロック状態においては、起倒体(30)に固設されたストライカー(71)がベース(20)に設けられたロック部(72)に拘束され、起倒体(30)の倒伏時にロックする。   The locking mechanism (70) holds and suppresses the raising body (30) when lying down. In the locked state, the striker (71) fixed to the raising body (30) is restrained by the lock portion (72) provided on the base (20), and locks when the raising body (30) falls down.

起倒体(30)の起立動作開始時に、ロック部(72)と電動油圧シリンダー(50)との間に設けられたロック解除機構(75)によりロック解除がなされ、拘束が解除されて引き続き起倒体(30)は起立する。   When the standing body (30) starts to stand up, the lock is released by the lock release mechanism (75) provided between the lock portion (72) and the electrohydraulic cylinder (50). The collapsed body (30) stands up.

起倒体(30)が倒伏しているとき、起倒体(30)の基部(31)とベース(20)の前部との間に空力対応のために設けられたスラントノーズ機構(80)は伸びてベース(20)の前部を覆う。スラントノーズ機構(80)は、起倒体(30)の起立時には折れて起倒体(30)の起立を妨げることはない。   A slant nose mechanism (80) provided for aerodynamic response between the base (31) of the raising body (30) and the front part of the base (20) when the raising body (30) is lying down. Extends to cover the front of the base (20). The slant nose mechanism (80) does not break when the erected body (30) is raised and does not prevent the erected body (30) from being raised.

指標を表示する標識部(40)に加え、起倒体(30)の後面に表示部(35)を設けたものは、2つの表示手段を持って多様性のある表示をすることができる。   The display unit (35) provided on the rear surface of the raising and lowering body (30) in addition to the indicator unit (40) for displaying the index can have a variety of displays with two display means.

本発明に係る標識装置によれば、標識部を支持する起倒体をベースに枢支し、電動油圧シリンダーにより起倒させるようにしたので、構造として簡単であり、安定していてコストもかからない。平行リンク機構により標識部が略水平な姿勢を保つよう支持したので、いずれの位置でも同一姿勢で視認でき、視認性に汎用性がある。バランサーとしてガススプリングを使用したので、駆動力を小さくして省エネルギーとなり、所定角度まで起倒体が起立するとガススプリングの反力が伝達しないようにしたので、起倒体の起立完了時の衝撃が減殺され、安定した動作ができる。起倒体の倒伏時に起倒体を拘束するロック機構を設けたので、倒伏したときのがたつきが抑えられ、安定する。起倒体の起立開始時に、動作にしたがってロック解除するようにしたので安定して動作する。起倒体の倒伏時に前部を覆うようスラントノーズ機構を設けたので、塵埃を防ぎ、空力的に優れたものにすることができる。指標を表示する標識部に加え、起倒体の後面に表示部を設けたものは、2つの表示手段を持って多様性のある表示をすることができる。   According to the marking device of the present invention, the raising and lowering body that supports the marking portion is pivotally supported by the base and is raised and lowered by the electric hydraulic cylinder, so that the structure is simple, stable, and inexpensive. . Since the sign portion is supported by the parallel link mechanism so as to maintain a substantially horizontal posture, it can be visually recognized at the same posture at any position, and the visibility is versatile. Since the gas spring is used as a balancer, the driving force is reduced to save energy, and the reaction force of the gas spring is not transmitted when the erection body stands up to a predetermined angle. It is diminished and can operate stably. A lock mechanism is provided to restrain the tilting body when it falls down. Since the lock is released according to the operation when the standing body starts standing, it operates stably. Since the slant nose mechanism is provided so as to cover the front part when the erection body falls down, dust can be prevented and aerodynamically excellent can be achieved. In addition to the indicator portion for displaying the indicator, the display portion provided on the rear surface of the raising and lowering body can display variously with two display means.
