Description
【０００１】[0001]
この考案は、１本または多段構造で使用する測量杆に関するものである。 The present invention relates to a surveying rod used in a single or multi-stage structure.
【０００２】[0002]
従来の測量杆の一般的な構造は、口径の異なる複数の杆部材が順次多段に嵌合 連結されてなり、これら各杆部材の表面に施された目盛が、測量杆の伸長時にお いて相互に連続するようにされている。そして、測量時には該杆部材を嵌合連結 し、測量杆を伸長状態として使用している。 The general structure of conventional surveying rods is that multiple rod members with different diameters are sequentially fitted in multiple stages. The scales that are connected and that are applied to the surface of each of these rod members are It is designed to be continuous with each other. And, at the time of surveying, fit and connect the rod member However, the surveying rod is used in an extended state.
【０００３】 ところで、電車の線路上や道路上、あるいは下水道の中等、昼間測量を行うた めには交通を遮断しなければならならず夜間しか測量を行えない場所や昼間でも 薄暗い場所で測量を行わなければならないことがしばしばあるが、上記のように 構成された測量杆では、そのような場所での測量にあっては、杆部材の表面に施 された目盛を読み取ることが困難となる。[0003] By the way, daytime surveys are conducted on railway tracks, on roads, in sewers, etc. In order to do this, you must cut off traffic, even in places where you can only measure at night or during the day. Often you have to take surveys in dim light, but as mentioned above With the constructed surveying rod, when performing surveying in such a place, It becomes difficult to read the graduated scale.
【０００４】 そこで、従来このような場所で測量を行う場合には、目盛の部分に懐中電灯等 でライトを当てる等、外部から目盛部分に光を当てた上で測量を行っていた。[0004] Therefore, when conducting surveying in such places, a flashlight or the like should be attached to the scale. For example, the measurement was performed after illuminating the scale part from the outside by illuminating it with.
【０００５】 また近頃では、上述のような測量杆を用いた測量方法に代わって、レーザー光 線等を利用した光波距離測定装置を用いた測量が行われることもある。[0005] Recently, instead of the surveying method using the surveying rod as described above, laser light is used. In some cases, a survey using a lightwave distance measuring device using a line or the like is performed.
【０００６】[0006]
しかしながら、このような方法では、以下に述べるような問題があり、その改 良が要望されていた。 However, such a method has the following problems, and the problem is solved. Good was requested.
【０００７】 すなわち、目盛の部分に外部から光を当てて測量を行うものでは、高い位置と なる測量杆の表面が十分明るくできず、しかも明るさにムラができ、見難い。[0007] That is, in the case of surveying by shining light on the scale part from the outside, The surface of the surveying rod is not bright enough and the brightness is uneven, making it difficult to see.
【０００８】 一方、レーザー光線等を利用する光波距離測定装置は、装置自身の構成が複雑 であり、製造単価が高い。したがって、これを比較的簡易な測量に使用すること は、測量にかかるコストの（従来の測量杆を用いる方法に比べて）上昇を招くこ とになる。[0008] On the other hand, the light-wave distance measuring device that uses a laser beam has a complicated configuration. Therefore, the manufacturing unit price is high. Therefore, use this for a relatively simple survey Can increase the cost of surveying (compared to conventional surveying rod methods). Becomes
【０００９】 本考案はかかる従来の問題点に鑑みてなされたものであって、多段構造を有す る測量杆において、測量杆を内側から発光させることによって、目盛を浮かび上 がらせ、夜間等においても使用することができ、しかも製造コストの安価な測量 杆を提供することを目的とする。[0009] The present invention has been made in view of such conventional problems and has a multi-stage structure. In the surveying rod, the scale is raised by illuminating the surveying rod from the inside. It can be used even at night and at night, and the manufacturing cost is low. The purpose is to provide a rod.

杆部材内部全長の反射部材に間隔をもって発光体が多数配設されており、この 発光体が発する光が、反射部材によって反射され、または直接に透光性を有する 杆部材を通過して外部に現れる。 A large number of light emitters are arranged at intervals on the reflecting member of the entire length of the rod member. Light emitted by the light-emitting body is reflected by the reflecting member or has a direct light-transmitting property. It passes through the rod member and appears outside.
【００１２】 また、発光体と杆部材との間に透光性を有する光拡散部材を介在させることに より、杆部材を通過する光を拡散し、杆部材表面に施された目盛を浮かび上がら せる。[0012] In addition, a light diffusing member having a light transmitting property is interposed between the light emitting body and the rod member. Light that diffuses through the rod member and raises the scale on the surface of the rod member. Let

【００２９】[0029]
以上詳述したように、本考案によれば、以下に列挙するような種々の特有の効 果が得られる。 As described above in detail, according to the present invention, various unique effects as listed below are provided. The fruit is obtained.
【００３０】 (1) 測量杆を構成する杆部材が透光性を有し、該杆部材は、内部全長にわたって に反射板と発光体とを有することから、発光体を発光させることにより、杆部材 自身が発光する。[0030] (1) The rod member that constitutes the surveying rod has a light-transmitting property, and the rod member covers the entire internal length. Since the reflecting plate and the light emitting body are provided in the rod, the rod member It emits light by itself.
【００３１】 したがって、暗い場所で測量を行う場合、懐中電灯等のライトを必要とせず、 測量をすることができる。[0031] Therefore, when surveying in a dark place, you do not need a light such as a flashlight, You can take a survey.
【００３２】 (2) 測量杆を構成する杆部材が透光性を有し、多段に伸縮自在に連結可能とされ 、該杆部材は、反射部材と発光体と光拡散部材とを有し、反射部材は、杆部材の 内部全長に杆部材を軸方向に貫通して取り付けられ、発光体は、反射部材全長に 間隔をもって配設され、光拡散部材は、透光性を有すると共に、杆部材の内面と 発光体との間に介在させて設けられていることから、発光体を発光させた場合に おいて、その発光体の発する光が光拡散部材を通過することによって拡散され、 外部に放出する。[0032] (2) The rod members that make up the surveying rod are translucent and can be connected in a multi-step retractable manner. The rod member has a reflecting member, a light emitting body, and a light diffusing member, and the reflecting member is a rod member. The rod is attached axially through the entire length of the inside, and the luminous body is attached to the entire length of the reflecting member. The light diffusing member, which is arranged with a space, has a light-transmitting property, and at the same time as the inner surface of the rod member. Since it is provided so as to be interposed between the light-emitting body and At this point, the light emitted by the light emitter is diffused by passing through the light diffusing member, Release to the outside.
【００３２】 したがって、発光体が発光した状態において、外部から測量杆を見たときに、 杆部材の全体が明るく光って見える。つまり、杆部材の表面に付された目盛が発 光体の発する光によって、全体的に浮かび上がる。さらに、発光体と光拡散部材 内面との間に光遮蔽部材を介在させることにより、内部から発する光が杆部材上 に点として現れることなく、全体が均一に明るく見え、目盛を鮮明に読み取るこ とができる。さらには、反射部材に白色を用いることにより、発光体が発する光 が反射部材によって反射して外部に発せられ、目盛を読みやすくする。[0032] Therefore, when the surveying rod is viewed from the outside when the luminous body emits light, The entire rod member looks bright and shiny. In other words, the scale attached to the surface of the rod member is It emerges as a whole due to the light emitted by the light body. Furthermore, the light emitter and the light diffusion member By interposing a light shielding member between the inner surface and the inner surface, the light emitted from the inside It does not appear as dots on the screen, and the whole looks evenly bright and the scale is clearly read. You can Furthermore, by using white for the reflecting member, the light emitted by the light-emitting body Is reflected by the reflection member and emitted to the outside, making the scale easy to read.
