Description

本発明は、一対のレール上を通過する列車の建築限界を測定し得る建築限界測定器に関するものである。   The present invention relates to a building limit measuring instrument capable of measuring the building limit of a train passing on a pair of rails.

列車がレール上を通過する際に周囲と干渉することなく安全に走行させるべく、通常、当該レールよりも外側において、列車の幅寸法に相当の余裕寸法を加えた空間が必要とされる。かかる空間を「建築限界」といい、当該建築限界内にホーム等の建築物が入り込まないよう設計する必要がある。然るに、従来より、一対のレールに跨って載置されるとともに、当該載置状態で建築限界位置まで延設した延設部を有した建築限界測定器が提案されるに至っている。   In order to travel safely without interfering with the surroundings when the train passes on the rail, a space obtained by adding a considerable margin to the width of the train is usually required outside the rail. Such a space is called “architectural limit”, and it is necessary to design such that a building such as a home does not enter the limit. However, conventionally, a building limit measuring instrument has been proposed which is placed across a pair of rails and has an extending portion extending to the building limit position in the mounted state.

従来の建築限界測定器は、特許文献1にて開示されているように、アルミ又はアルミ合金から成り、一対のレールに跨って載置されるとともに、その載置された状態で建築限界位置まで延設した延設部を有する測定器本体と、該測定器本体の一部に形成されるとともに、一方のレールの縁部と当接可能とされ、当該当接箇所が建築限界を測定する際の基準点を成す基準部材とを具備し、基準部材は、当該基準部材を挟んで両側に位置する測定器本体を互いに絶縁し得る樹脂材から成るものとされていた。   As disclosed in Patent Document 1, the conventional building limit measuring instrument is made of aluminum or an aluminum alloy, and is placed across a pair of rails. A measuring instrument main body having an extended extension part, and formed on a part of the measuring instrument main body and capable of coming into contact with an edge of one rail, and when the contact point measures a building limit The reference member is made of a resin material that can insulate the measuring instrument bodies located on both sides of the reference member.

特開2010−261864号公報JP 2010-261864 A

しかしながら、上記従来の建築限界測定器においては、基準部材は、当該基準部材を挟んで両側に位置する測定器本体を互いに絶縁し得る樹脂材から成るものとされていたので、建築限界測定時、測定器本体を一対のレールに跨って載置させたときに電気的に短絡してしまうのを抑制することができるものの、以下の如き問題がある。すなわち、測定器本体を一対のレールに跨って載置する際、常に基準部材をレールに当接させ得るとは限らず、建築限界測定作業において測定器本体がレールに触れてしまう可能性があり、その場合、一対のレールが電気的に短絡して導通してしまい、信号線等に不具合を生じさせてしまう虞があった。   However, in the above-mentioned conventional building limit measuring instrument, the reference member is made of a resin material that can insulate the measuring instrument bodies located on both sides of the reference member. Although it is possible to suppress an electrical short circuit when the measuring instrument body is placed across a pair of rails, there are the following problems. That is, when placing the measuring instrument main body across a pair of rails, the reference member cannot always be brought into contact with the rail, and there is a possibility that the measuring instrument main body touches the rail in the construction limit measurement work. In this case, the pair of rails are electrically short-circuited to cause conduction, which may cause a problem in the signal line or the like.

本発明は、このような事情に鑑みてなされたもので、強度を維持しつつ軽量化を図るとともに一対のレールに跨って載置させた際に電気的に短絡して導通してしまうのを確実に回避することができる建築限界測定器を提供することにある。   The present invention has been made in view of such circumstances, and it is possible to reduce the weight while maintaining the strength and to electrically conduct by short-circuiting when placed across a pair of rails. An object of the present invention is to provide a building limit measuring device that can be avoided reliably.

以下、本発明の実施形態について図面を参照しながら具体的に説明する。
第1の実施形態に係る建築限界測定器は、一対のレール上を通過する列車の建築限界を測定し得るものであり、図1〜3に示すように、列車が通過し得る一対のレールRに跨って載置可能とされた長尺部材から成る測定器本体1と、該測定器本体1の端部から延設された延設部(第1延設部2及び第2延設部3)と、取手(とって)4と、ハンドル部材5と、車輪6と、固定手段8と、本体用固定手段9とから主に構成されている。ここで、建築限界とは、一対のレールRよりも外側において、列車の幅寸法に相当の余裕寸法を加えた空間のことをいい、本明細書においては符号G(図1参照)で示すこととする。
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The building limit measuring instrument according to the first embodiment can measure the building limit of a train passing on a pair of rails, and as shown in FIGS. 1 to 3, a pair of rails R through which the train can pass. Measuring device main body 1 made of a long member that can be placed across the extension, and extending portions (first extending portion 2 and second extending portion 3) extending from the end of measuring device main body 1 ), A handle 4, a handle member 5, a wheel 6, a fixing means 8, and a main body fixing means 9. Here, the construction limit means a space obtained by adding a considerable margin dimension to the width dimension of the train outside the pair of rails R. In this specification, it is indicated by a symbol G (see FIG. 1). And

測定器本体1は、第1測定器本体1a及び第2測定器本体1bで構成されており、建築限界の測定時に一対のレールRに跨って載置されるものである。具体的には、第1測定器本体1a及び第2測定器本体1bは、揺動軸L3にて連結されるとともに当該揺動軸L3を中心として互いに揺動可能とされており、建築限界の測定時には、左右方向(第1測定器本体1a及び第2測定器本体1bの長手方向)に広がって略直線状に連結された状態(図1、2参照)となるものである。   The measuring device main body 1 is composed of a first measuring device main body 1a and a second measuring device main body 1b, and is placed across a pair of rails R at the time of measuring the building limit. Specifically, the first measuring device main body 1a and the second measuring device main body 1b are connected by a swing shaft L3 and swingable with respect to the swing shaft L3. At the time of measurement, it extends in the left-right direction (longitudinal direction of the first measuring device main body 1a and the second measuring device main body 1b) and is connected in a substantially linear shape (see FIGS. 1 and 2).

また、本実施形態に係る測定器本体1(第1測定器本体1a及び第2測定器本体1b)は、絶縁性の樹脂材から成るもので、具体的にはモノマーキャスティングナイロンにて構成されている。このモノマーキャスティングナイロンは、比重:1.15〜1.17(g/cc)、硬度:R95〜120、引張強さ:770〜980(kgf/cm)、伸び:30〜320(%)、弾性係数:24〜31(10kgf/cm)、摩擦係数:0.35、衝撃強度:2〜3(アイゾットノッチ)なる機械的性質を有するとともに、体積固有抵抗:1012〜1015(Ω・cm)、絶縁破壊強さ:30〜40(KV/mm)、誘電率:3.7、誘電体力率:200(10−4)なる電気的性質を有している。このように、モノマーキャスティングナイロンを材質とすることにより、軽量且つ高強度であるとともに高い絶縁特性を有した測定器本体1を得ることができる。 Further, the measuring instrument main body 1 (the first measuring instrument main body 1a and the second measuring instrument main body 1b) according to the present embodiment is made of an insulating resin material, and is specifically composed of monomer casting nylon. Yes. This monomer casting nylon has a specific gravity of 1.15 to 1.17 (g / cc), hardness: R95 to 120, tensile strength: 770 to 980 (kgf / cm 2 ), elongation: 30 to 320 (%), Elasticity coefficient: 24 to 31 (10 3 kgf / cm 2 ), friction coefficient: 0.35, impact strength: 2 to 3 (Izod notch) and volume resistivity: 10 12 to 10 15 ( Ω · cm), dielectric breakdown strength: 30 to 40 (KV / mm), dielectric constant: 3.7, dielectric power factor: 200 (10 −4 ). Thus, by using monomer-casting nylon as a material, it is possible to obtain a measuring instrument body 1 that is lightweight and has high strength and has high insulating properties.

延設部(第1延設部2及び第2延設部3)は、測定器本体1(第1測定器本体1a及び第2測定器本体1b)の両端部にそれぞれ取り付けられ、測定器本体1が一対のレールRに跨って載置された状態で建築限界位置まで延設されるものである。具体的には、延設部は、第1延設部2及び第2延設部3を連結して構成されており、これら第1延設部2及び第2延設部3は、揺動軸L2にて連結されるとともに当該揺動軸L2を中心として互いに揺動可能とされている。   The extending portions (the first extending portion 2 and the second extending portion 3) are attached to both ends of the measuring device main body 1 (the first measuring device main body 1a and the second measuring device main body 1b), respectively. 1 is extended to a construction limit position in a state where it is placed across a pair of rails R. Specifically, the extension part is configured by connecting the first extension part 2 and the second extension part 3, and the first extension part 2 and the second extension part 3 are swung. The shafts L2 are connected to each other and can swing around the swinging shaft L2.

すなわち、第1延設部2は、その基端が測定器本体1の両端に連結されるとともに、先端が第2延設部3の基端と連結されており、第1延設部2と測定器本体1とが揺動軸L1にて揺動可能とされ、且つ、第1延設部2と第2延設部3とが揺動軸L2にて揺動可能とされている。そして、建築限界の測定時には、第1延設部2を測定器本体1に対して略直線状に広げるとともに、第2延設部3を第1延設部2に対して所定角度傾斜させた状態まで広げるものとされ、この状態(一対のレールR上に車輪6が乗った状態)において、第2延設部3の先端部3aの位置が建築限界Gに合致するものとされている。   That is, the first extending portion 2 has a base end connected to both ends of the measuring device main body 1 and a tip connected to the base end of the second extending portion 3. The measuring device main body 1 can be swung by a swinging shaft L1, and the first extending portion 2 and the second extending portion 3 can be swung by a swinging shaft L2. And at the time of the measurement of a construction limit, while extending the 1st extension part 2 to the measuring device main body 1 substantially linearly, the 2nd extension part 3 was made to incline the predetermined angle with respect to the 1st extension part 2. In this state (a state in which the wheels 6 are on the pair of rails R), the position of the tip 3a of the second extending portion 3 matches the building limit G.

また、本実施形態に係る延設部は、測定器本体1が一対のレールRに跨って載置された状態(建築限界の測定時)で建築限界位置まで延設した延設状態(図1〜3参照)と、搬送時等において当該測定器本体1に対して折り畳まれた折り畳み状態(図7参照)との間で移動(揺動)可能とされている。すなわち、延設状態から、揺動軸L2を中心として第2延設部3を揺動させて第1延設部2に対して前後方向に重ねた状態とした後、揺動軸L1を中心として第1延設部2を揺動させ、測定器本体1に対して前後方向に重ねた状態とすれば折り畳み状態とされるのである。   Moreover, the extended part which concerns on this embodiment is the extended state extended to the building limit position in the state (at the time of measurement of a building limit) in which the measuring device main body 1 was laid over a pair of rails R (FIG. 1). -3) and a folded state (see FIG. 7) that is folded with respect to the measuring instrument main body 1 during transportation or the like. That is, from the extended state, the second extending portion 3 is swung around the swinging shaft L2 and overlapped in the front-rear direction with respect to the first extending portion 2, and then the swinging shaft L1 is centered. If the first extending portion 2 is swung and overlapped with the measuring instrument main body 1 in the front-rear direction, the folded state is obtained.

しかるに、本実施形態においては、延設部(第1延設部2及び第2延設部3)が延設状態及び折り畳み状態のとき、それぞれ測定器本体1に対して当該延設部を位置決めしつつ固定する固定手段8が形成されている。この固定手段8は、図5に示すように、第1延設部2の所定部位に取り付けられた所謂インデックスプランジャから成り、操作部Pと、係止部Lと、ナットnとから主に構成されている。   However, in this embodiment, when the extended portions (the first extended portion 2 and the second extended portion 3) are in the extended state and the folded state, the extended portion is positioned with respect to the measuring instrument main body 1, respectively. However, fixing means 8 for fixing is formed. As shown in FIG. 5, the fixing means 8 includes a so-called index plunger attached to a predetermined portion of the first extending portion 2, and mainly includes an operation portion P, a locking portion L, and a nut n. Has been.

係止部Lは、操作部Pと連結されるとともに、第1延設部2の表面から出没可能とされており、内蔵された付勢手段(図示せず)により突出方向に向かって付勢されている。そして、延設状態において、係止部Lは、測定器本体1(第1測定器本体1a及び第2測定器本体1b)の所定位置に形成された係止穴H1に挿入することにより第1延設部2を係止可能とされており、かかる係止により測定器本体1に対して延設部(第1延設部2)を位置決めしつつ固定可能とされている。   The locking portion L is connected to the operation portion P and can be projected and retracted from the surface of the first extending portion 2, and is biased toward the protruding direction by a built-in biasing means (not shown). Has been. In the extended state, the locking portion L is inserted into a locking hole H1 formed at a predetermined position of the measuring device main body 1 (the first measuring device main body 1a and the second measuring device main body 1b). The extending portion 2 can be locked, and the locking can be fixed while positioning the extending portion (first extending portion 2) with respect to the measuring instrument main body 1 by such locking.

一方、操作部Pを引っ張り操作して係止部Lを付勢力に抗して没入方向に移動させることにより、当該係止部Lの係止穴H1に対する係止を解くことが可能とされている。この係止を解いた状態で延設部(第1延設部2及び第2延設部3)を折り畳み状態とすることができる。かかる折り畳み状態としたとき、固定手段8の係止部Lと対応した所定位置には、係止穴H1と同様の係止穴H1’(図2参照)が形成されており、当該係止部Lを当該係止穴H1’に挿入することにより第1延設部2を折り畳み状態で係止可能とされている。かかる係止により測定器本体1に対して延設部(第1延設部2)を位置決めしつつ固定可能とされている。   On the other hand, by pulling the operating portion P and moving the locking portion L in the immersion direction against the urging force, the locking portion L can be unlocked with respect to the locking hole H1. Yes. The extended portions (the first extended portion 2 and the second extended portion 3) can be folded in a state where this locking is released. When in such a folded state, a locking hole H1 ′ (see FIG. 2) similar to the locking hole H1 is formed at a predetermined position corresponding to the locking portion L of the fixing means 8, and the locking portion The first extending portion 2 can be locked in a folded state by inserting L into the locking hole H1 ′. By such locking, the extension portion (first extension portion 2) can be fixed with respect to the measuring instrument main body 1 while being positioned.

また、本実施形態においては、延設部(第1延設部2及び第2延設部3)を折り畳み状態とした後、さらに測定器本体1を折り畳み可能とされている。すなわち、折り畳み状態(図7参照)において、揺動軸L3を中心として第1測定器本体1a及び第2測定器本体1bを互いに揺動させ(図8参照)、これら第1測定器本体1a及び第2測定器本体1bを前後方向に重ね合わせることで、図9、10に示すように、測定器本体1を折り畳んだ収納状態とすることができる。   Moreover, in this embodiment, after making the extension part (the 1st extension part 2 and the 2nd extension part 3) into a folding state, the measuring device main body 1 can be further folded. That is, in the folded state (see FIG. 7), the first measuring device main body 1a and the second measuring device main body 1b are swung with respect to each other about the rocking axis L3 (see FIG. 8). By overlapping the second measuring device main body 1b in the front-rear direction, the measuring device main body 1 can be folded and stored as shown in FIGS.

またさらに、本実施形態においては、第1測定器本体1a及び第2測定器本体1bを位置決めしつつ固定する本体用固定手段9が形成されている。この本体用固定手段9は、既述した固定手段8と同様の部品から成るものであり、図6に示すように、第1測定器本体1aの所定部位に取り付けられた所謂インデックスプランジャから成り、操作部Pと、係止部Lと、ナットnとから主に構成されている。   Furthermore, in the present embodiment, main body fixing means 9 for fixing the first measuring device main body 1a and the second measuring device main body 1b while positioning them is formed. The main body fixing means 9 is composed of the same parts as the fixing means 8 described above, and as shown in FIG. 6, is composed of a so-called index plunger attached to a predetermined part of the first measuring device main body 1a. It is mainly composed of an operation part P, a locking part L, and a nut n.

係止部Lは、操作部Pと連結されるとともに、第1測定器本体1aの表面から出没可能とされており、内蔵された付勢手段(図示せず)により突出方向に向かって付勢されている。そして、延設状態及び折り畳み状態において、係止部Lは、第2測定器本体1bの所定位置に形成された係止穴H2に挿入することにより第2測定器本体1bを係止可能とされており、かかる係止により第1測定器本体1a及び第2測定器本体1bを互いに位置決めしつつ固定可能とされている。   The locking portion L is connected to the operation portion P and can be projected and retracted from the surface of the first measuring device main body 1a, and is biased toward the protruding direction by a built-in biasing means (not shown). Has been. In the extended state and the folded state, the locking portion L can be locked to the second measuring device main body 1b by being inserted into a locking hole H2 formed at a predetermined position of the second measuring device main body 1b. Thus, the first measuring device main body 1a and the second measuring device main body 1b can be fixed while being positioned with respect to each other.

一方、操作部Pを引っ張り操作して係止部Lを付勢力に抗して没入方向に移動させることにより、当該係止部Lの係止穴H2に対する係止を解くことが可能とされている。この係止を解いた状態で第1測定器本体1a及び第2測定器本体1bを収納状態とすることができる。かかる収納状態において、予め取り外されていたハンドル部材5と共にバンド等で結束させれば、一括して搬送することができる。   On the other hand, it is possible to unlock the locking portion L with respect to the locking hole H2 by pulling the operation portion P and moving the locking portion L in the immersion direction against the urging force. Yes. The first measuring device main body 1a and the second measuring device main body 1b can be placed in the stored state in a state in which this locking is released. In such a storage state, if the handle member 5 that has been removed in advance is bundled with a band or the like, it can be transported collectively.

ここで、本実施形態においては、図9、10に示すように、測定器本体1が折り畳まれた状態(収納状態)において、左右両端の車輪6が当該測定器本体1の延設方向(図10中a方向)に対してずれた位置とされている。すなわち、収納状態においては、左右の車輪6が互いにオフセットした状態とされており、各車輪6に形成されたフランジ部6aが図9におけるb方向に重ならないようになっている。   Here, in the present embodiment, as shown in FIGS. 9 and 10, in the state where the measuring instrument main body 1 is folded (stored state), the right and left wheels 6 extend in the extending direction of the measuring instrument main body 1 (see FIG. 10 in the a direction). That is, in the housed state, the left and right wheels 6 are offset from each other, and the flange portions 6a formed on the wheels 6 do not overlap in the direction b in FIG.

さらに、測定器本体1の左右両端(第1測定器本体1a及び第2測定器本体1bの各先端)には、それぞれ支持部材7が取り付けられており、当該支持部材7に車輪6が回転可能に支持されている。かかる車輪6は、一対のレールR上をそれぞれ転動可能とされ、各レールRからの脱落を抑制するためのフランジ部6aが形成されたものである。なお、本実施形態に係る車輪6は、樹脂材を成形して成るものとされているが、他の材料であってもよい。しかして、車輪6を一対のレールR上に載置することにより、当該車輪6を介して測定器本体1が一対のレールRに跨って載置されることとなる。   Furthermore, a support member 7 is attached to each of the left and right ends of the measuring instrument main body 1 (the respective leading ends of the first measuring instrument main body 1a and the second measuring instrument main body 1b), and the wheel 6 can rotate on the support member 7. It is supported by. The wheels 6 can roll on a pair of rails R, and are formed with flange portions 6a for preventing the rails R from dropping off. In addition, although the wheel 6 which concerns on this embodiment shall be formed by shape | molding a resin material, another material may be sufficient. Thus, by placing the wheel 6 on the pair of rails R, the measuring device main body 1 is placed across the pair of rails R via the wheels 6.

取手4は、測定器本体1の略中央に形成された例えば金属製部品から成り、建築限界測定器の搬送時に作業者が把持可能な形状(上方に逆U字状に突出した形状)とされている。この取手4は、測定器本体1の上面又は側面から突出して作業者が搬送時に把持可能なものであれば足り、その形状や材質等については種々のものが任意選択され得る。かかる取手4の所定部位には、上方に突出形成された係止ボス部Nが取り付けられており、この係止ボス部Nにハンドル部材5が係止可能とされている。   The handle 4 is made of, for example, a metal part formed substantially at the center of the measuring instrument main body 1 and has a shape that can be gripped by an operator when the construction limit measuring instrument is conveyed (a shape protruding upward in an inverted U shape). ing. The handle 4 is sufficient if it protrudes from the upper surface or side surface of the measuring instrument main body 1 and can be gripped by an operator during transportation, and various shapes, materials, and the like can be arbitrarily selected. A locking boss N that protrudes upward is attached to a predetermined portion of the handle 4, and the handle member 5 can be locked to the locking boss N.

ハンドル部材5は、取手4に対して脱着可能とされた棒状部材から成り、建築限界の測定時に当該取手4に取り付けられて測定者が把持可能なものである。具体的には、ハンドル部材5は、図3に示すように、長手方向に延びて測定者が把持可能な把持部5aと、該把持部5aの先端に形成され、測定器本体1の取手4に係止可能な係止部5bとから主に構成されており、係止部5bには、図4に示すように、左右の縁部に係止ボス部Nと係止可能な切欠き5ba、5bbが形成されている。   The handle member 5 is composed of a rod-like member that can be attached to and detached from the handle 4, and is attached to the handle 4 and can be gripped by the measurer when measuring the building limit. Specifically, as shown in FIG. 3, the handle member 5 extends in the longitudinal direction and is formed at a gripper 5 a that can be gripped by a measurer, and a handle 4 of the measuring instrument body 1. The locking portion 5b is mainly composed of a locking portion 5b, and as shown in FIG. 4, the locking portion 5b has a notch 5ba that can be locked to the locking boss portion N on the left and right edges. 5bb is formed.

しかして、図4(a)で示す如く、切欠き5baに係止ボス部Nを係止させるようにすれば、ハンドル部材5を測定器本体1の前方から取り付けることができるとともに、同図(b)で示す如く、切欠き5bbに係止ボス部Nを係止させるようにすれば、ハンドル部材5を測定器本体1の後方から取り付けることができるようになっている。すなわち、本実施形態に係るハンドル部材5は、測定器本体1に対して前後何れの方向からも取り付け可能とされているのである。   Thus, as shown in FIG. 4A, the handle member 5 can be attached from the front of the measuring instrument body 1 by locking the locking boss portion N in the notch 5ba. As shown in b), the handle member 5 can be attached from the rear side of the measuring instrument body 1 by locking the locking boss portion N in the notch 5bb. That is, the handle member 5 according to this embodiment can be attached to the measuring instrument main body 1 from either the front or rear direction.

なお、ハンドル部材5を測定器本体1の前方から取り付けた状態においては、把持部5aが所定角度傾斜しつつ前方に延設されるので、測定者は当該把持部5aを把持しつつ測定器本体1を後方に向かって移動させるものとされ、ハンドル部材5を測定器本体1の後方から取り付けた状態においては、把持部5aが所定角度傾斜しつつ後方に延設されるので、測定者は当該把持部5aを把持しつつ測定器本体1を前方に向かって移動させるものとされる。   In the state in which the handle member 5 is attached from the front of the measuring instrument main body 1, the gripper 5a extends forward while being inclined at a predetermined angle, so that the measurer holds the gripping part 5a and the measuring instrument main body. 1 is moved rearward, and in a state where the handle member 5 is attached from the rear of the measuring instrument main body 1, the gripper 5a extends rearward while being inclined at a predetermined angle. The measuring instrument main body 1 is moved forward while gripping the grip portion 5a.

上記実施形態によれば、測定器本体1(第1測定器本体1a及び第2測定器本体1b)は、絶縁性の樹脂材から成るので、強度を維持しつつ軽量化を図るとともに一対のレールRに跨って載置させた際に誤って電気的に短絡させてしまい導通してしまうのを確実に回避することができる。特に、本実施形態に係る測定器本体1は、モノマーキャスティングナイロンから成るので、より高強度とすることができるとともに一層の軽量化を図ることができる。   According to the above embodiment, the measuring instrument main body 1 (the first measuring instrument main body 1a and the second measuring instrument main body 1b) is made of an insulating resin material. When placed across R, it is possible to reliably avoid electrical short-circuiting and conduction. In particular, the measuring instrument main body 1 according to the present embodiment is made of monomer casting nylon, so that it can have higher strength and can be further reduced in weight.

また、測定器本体1の略中央には、搬送時に把持可能な取手4が形成されたので、より確実かつ円滑に測定器本体1を持つことができる。さらに、取手4に対して脱着可能とされた棒状部材から成り、建築限界の測定時に当該取手4に取り付けられて測定者が把持可能なハンドル部材5を具備したので、建築限界の測定をより円滑に行わせることができる。特に、ハンドル部材5が取手4に取り付け可能とされているので、取手4の突出寸法だけハンドル部材5の延設寸法を小さくすることができる。またさらに、ハンドル部材5は、測定器本体1に対して前後何れの方向からも取り付け可能とされたので、建築限界の測定作業をより円滑に行わせることができる。   In addition, since the handle 4 that can be gripped at the time of conveyance is formed in the approximate center of the measuring instrument main body 1, the measuring instrument main body 1 can be held more reliably and smoothly. Furthermore, it is composed of a rod-like member that can be attached to and detached from the handle 4, and has a handle member 5 that is attached to the handle 4 and can be gripped by the measurer when measuring the building limit, so that the building limit can be measured more smoothly. Can be done. In particular, since the handle member 5 can be attached to the handle 4, the extension dimension of the handle member 5 can be reduced by the protruding dimension of the handle 4. Furthermore, since the handle member 5 can be attached to the measuring instrument main body 1 from either the front or rear direction, the construction limit measurement work can be performed more smoothly.

なお、上記実施形態によれば、延設部(第1延設部2及び第2延設部3)が延設状態及び折り畳み状態のとき、それぞれ測定器本体1に対して当該延設部を位置決めしつつ固定する固定手段8を具備したので、延設状態における建築限界の測定を精度よく行わせることができるとともに、折り畳み状態における搬送作業を円滑かつ良好に行わせることができる。   In addition, according to the said embodiment, when the extension part (the 1st extension part 2 and the 2nd extension part 3) is an extended state and a folding state, the said extension part is each with respect to the measuring device main body 1. Since the fixing means 8 for fixing while positioning is provided, it is possible to accurately measure the building limit in the extended state, and to smoothly and satisfactorily carry the conveying work in the folded state.

また、測定器本体1は、折り畳み可能とされたので、建築限界測定器の搬送時、より小型なものとすることができ、より一層、円滑かつ容易な搬送作業とすることができる。さらに、測定器本体1の左右両端には、一対のレールR上をそれぞれ転動可能とされ、各レールRからの脱落を抑制するためのフランジ部6aが形成された車輪6が取り付けられるとともに、測定器本体1が折り畳まれた状態において、左右両端の車輪6が当該測定器本体1の延設方向に対してずれた位置とされるので、建築限界測定器の搬送時、より一層小型なものとすることができる。   Moreover, since the measuring device main body 1 can be folded, it can be made smaller when the construction limit measuring device is transported, and the transporting operation can be made smoother and easier. Furthermore, wheels 6 are attached to the left and right ends of the measuring instrument main body 1 so as to be able to roll on the pair of rails R, respectively, and formed with flange portions 6a for preventing the rails R from falling off. In the state in which the measuring instrument main body 1 is folded, the wheels 6 at the left and right ends are shifted from the extending direction of the measuring instrument main body 1, so that it is even smaller when transporting the building limit measuring instrument. It can be.
