屋内、屋外を問わず、建築現場では建築の基準となる鉛直線や水平線を描く墨 出し作業が必須である。近年、レ−ザ−ビ−ムを用いた墨出し装置が採用されて いる。図１３は、本考案の基礎となる構成のレ−ザ−ビ−ム式墨出し装置（以下 、墨出し装置と略す）３の正面図であり、従来技術の項で参照されると共に、後 述される実施例の項でも参照される。墨出し装置３は、横断面が多角形状の頭部 ハウジング４を有し、頭部ハウジング４の下面周上に三脚６が１２０度の間隔で 配置される。この頭部ハウジング４の上面および下面には、それぞれ円形開口が 設けられており、下面開口の周囲にジャイロ８が固定されている。そして、レ− ザ−管１０が内部に同軸に固定された例えばアルミニウム製の保護菅１２が、頭 部ハウジング４の下面開口を通して下方に突出する。ジャイロ８は、この保護管 １２の外周面を部分的に支持し、レ−ザ−管１０の中心軸が常に鉛直方向を向く ようにレ−ザ−管１０を内蔵した保護管１２の姿勢を制御する。 Whether it is indoors or outdoors, it is essential for construction sites to perform marking work that draws the vertical and horizontal lines that are the standard of construction. In recent years, a marking-out device using a laser beam has been adopted. FIG. 13 is a front view of a laser beam type marking-out device (hereinafter abbreviated as marking-out device) 3 which is the basis of the present invention. Reference is also made to the Examples section mentioned. The marking-out device 3 has a head housing 4 having a polygonal cross section, and tripods 6 are arranged on the lower surface of the head housing 4 at intervals of 120 degrees. Circular openings are provided on the upper surface and the lower surface of the head housing 4, and a gyro 8 is fixed around the lower surface opening. Then, a protective tube 12 made of, for example, aluminum, in which the laser tube 10 is coaxially fixed, projects downward through an opening on the lower surface of the head housing 4. The gyro 8 partially supports the outer peripheral surface of the protective tube 12, and the posture of the protective tube 12 with the built-in laser tube 10 is set so that the central axis of the laser tube 10 always faces the vertical direction. Control.
【０００３】 レ−ザ−管１０は、例えば１ｍＷ直進偏向形のヘリウムネオンガスレ−ザ−管 であって、上下両端から中心軸に沿ってそれぞれレ−ザ−ビ−ムを放射する。保 護管１２の上端にはこれと同軸に円筒形の鏡胴１５が回動自在に取り付けられて おり、鏡胴１５が頭部ハウジング４の上面開口を通して上方に突出する。鏡胴１ ５のカバ−１６内には、中心軸に対して４５度の角度で図示しない円形ハ−フミ ラ−が配置されており、レ−ザ−管１０から鉛直上向きに放射されたレ−ザ−ビ −ムが鉛直方向と水平方向とに分けられて、鏡胴カバ−１６の上面および周囲に それぞれ設けられた放射窓１８，２０を通して投射される。鉛直上向き方向のレ −ザ−ビ−ムは、天井面に十字線を描くように変換され、水平方向のレーザ−ビ −ムは鉛直扇面状に変換される。保護管１２の下端２２は先細状に形成され、レ −ザ−ビ−ムが保護管１２の下端開口から投射される。The laser tube 10 is, for example, a 1 mW straight deflection type helium neon gas laser tube, and radiates laser beams from both upper and lower ends along the central axis. A cylindrical lens barrel 15 is rotatably attached to the upper end of the protective tube 12 coaxially therewith, and the lens barrel 15 projects upward through an upper opening of the head housing 4. In the cover 16 of the lens barrel 15, a circular half mirror (not shown) is arranged at an angle of 45 degrees with respect to the central axis, and the laser beam emitted from the laser tube 10 is radiated vertically upward. The beam is divided into a vertical direction and a horizontal direction and is projected through radiation windows 18 and 20 provided on the upper surface and the periphery of the lens barrel cover 16, respectively. The laser beam in the vertical upward direction is converted so as to draw a cross line on the ceiling surface, and the laser beam in the horizontal direction is converted into a vertical fan surface. The lower end 22 of the protective tube 12 is formed in a tapered shape, and the laser beam is projected from the lower end opening of the protective tube 12.
【０００４】 保護管１２の下向き突出部分は、下端の先細状の先細部２２を除き、保護管１ ２と同軸に頭部ハウジング４の下面に固定された例えばアルミニウムからなる円 筒形の風防２４で覆われている。この風防２４の下端部外周面には、２本のＯリ ング２６を介して透明プラスチックからなるストッパ−管２８が昇降自在に嵌合 装着されている。また、ストッパ−管２８の内部には、保護管２の先細部２２が 遊嵌可能な孔３０を有するストッパ−プレ−ト３２が横向きに設けられている。 風防２４の周面上にはストッパ−管２８の上方位置につまみ３４が１２０度等間 隔に螺入されており、各つまみ３４の先端を保護管１２の外周面に当接させてこ れを固定することができる。なお、ジャイロ８およびレ−ザ−管１０は、電源コ −ド３６を通して電気の供給を受けて作動する。The downward projecting portion of the protective tube 12 is a cylindrical windshield 24 made of, for example, aluminum, which is fixed to the lower surface of the head housing 4 coaxially with the protective tube 12 except for the tapered taper 22 at the lower end. Is covered with. On the outer peripheral surface of the lower end portion of the windshield 24, a stopper tube 28 made of transparent plastic is fitted and mounted via two O-rings 26 so as to be movable up and down. Further, inside the stopper tube 28, a stopper plate 32 having a hole 30 into which the tapered portion 22 of the protection tube 2 can be loosely fitted is provided sideways. On the peripheral surface of the windshield 24, knobs 34 are screwed into the upper position of the stopper tube 28 at equal intervals of 120 degrees, and the tips of the knobs 34 are brought into contact with the outer peripheral surface of the protective tube 12. Can be fixed. The gyro 8 and the laser tube 10 are operated by being supplied with electricity through the power cord 36.
【０００５】 次に、以上に説明したレ−ザ−式墨出し装置３の使用法法について説明する。 まず、床面に印した地墨上に三脚６を用いて墨出し装置３を立てる。そして、つ まみ３４を緩め、ストッパ−管２８を下げた状態で、電源コ−ド３６を通してジ ャイロ８およびレ−ザ−管１０に電気を供給する。この際、床面が多少傾斜して いても、ジャイロ８の作用によりレ−ザ−管１０の中心軸が鉛直姿勢に調整され る。ただし、レ−ザ−管１０と一体の保護管１２の振れが大きい場合には、スト ッパ−管２８を上げて保護管１２の先細部２２をストッパ−プレ−ト３２の孔３ ０に遊嵌させれば、保護管１２の振れを制限することができる。そして各つまみ ３４をねじ込んで先端を保護管１２の外周面に当接させることにより、保護管１ ２の停止姿勢すなわちレ−ザ−管１０の中心軸の鉛直姿勢を保持させる。この際 、レ−ザ−管１０から上下方向に放射されるレ−ザ−ビ−ムが鉛直線上を通る。Next, a method of using the laser type marking device 3 described above will be described. First, the marking-out device 3 is set up on the ground marking marked on the floor using the tripod 6. Then, with the knob 34 loosened and the stopper tube 28 lowered, electricity is supplied to the gyro 8 and the laser tube 10 through the power cord 36. At this time, even if the floor surface is slightly inclined, the central axis of the laser tube 10 is adjusted to the vertical posture by the action of the gyro 8. However, when the deflection of the protection tube 12 integrated with the laser tube 10 is large, the stopper tube 28 is raised and the tapered portion 22 of the protection tube 12 is inserted into the hole 30 of the stopper plate 32. By loosely fitting, the deflection of the protection tube 12 can be limited. Then, the knobs 34 are screwed into each other to bring the tips into contact with the outer peripheral surface of the protective tube 12, thereby maintaining the protective tube 12 in a stopped posture, that is, the vertical posture of the central axis of the laser tube 10. At this time, the laser beam emitted from the laser tube 10 in the vertical direction passes along the vertical line.
【０００６】 鉛直下向きに放射されるレ−ザ−ビ−ムは、保護管１２の先細部開口を通して 下方に直進し、床面にスポットとして投影される。このスポットが前記の地墨に 正確に合致するように墨出し装置３全体の位置を微調整する。一方、レ−ザ−管 １０から鉛直上向きに放射されるレ−ザ−ビ−ムは、一部が鏡胴１５内のハ−フ ミラ−を透過して十字線に変換されて直進し、放射窓１８を通して天井面に投射 される。したがって、地墨に対して鉛直真上の位置の天井面に十字線が投影され る。残余のレ−ザ−ビ−ムは、ハ−フミラ−で反射して放射窓２０を通して水平 方向に鉛直扇面状に投射される。The laser beam emitted vertically downward goes straight through the tapered opening of the protective tube 12 and is projected as a spot on the floor. The position of the entire marking-out device 3 is finely adjusted so that this spot exactly matches the above-mentioned ground marking. On the other hand, a part of the laser beam radiated vertically upward from the laser tube 10 is transmitted through the half mirror in the lens barrel 15 to be converted into a cross hair and goes straight. It is projected on the ceiling surface through the radiation window 18. Therefore, the crosshairs are projected on the ceiling surface which is directly above the ground ink. The remaining laser beam is reflected by the half mirror and projected horizontally through the radiation window 20 in the form of a vertical fan surface.
【０００７】 したがって、このレ−ザ−式墨出し装置３を使用すれば、床面上の地墨を基準 として天井面への鉛直墨出しができるばかりでなく、壁面上に鉛直線を描くこと ができる。Therefore, by using this laser type marking-out device 3, not only the marking on the ceiling can be performed vertically on the basis of the ground marking on the floor, but also a vertical line can be drawn on the wall surface. You can

このような従来の墨出し装置３では、天井面に十字線を描くことができるが、 壁面には鉛直線を描くのみであり、壁面に十字線を描く必要がある場合に対応で きないという不具合がある。また、本件出願人は、壁面にスポットを描き、前記 保護管を回動させて壁面に水平方向の２点を設定できる墨出し装置を提案したが 、この提案になる墨出し装置では、壁面に水平線を描くことができず、この点で 不具合がある。本件出願人は、さらに壁面に十字線を描き、天井面にスポットを 描く墨出し装置を提案しているが、天井面および壁面のいずれにも十字線を描く 必要がある場合には、天井面に十字線を描く墨出し装置とこの壁面に十字線を描 く墨出し装置とを併用しなければならず、両装置の位置決めに多大な手間を要し 、かつ墨出しに必要な構成が大型化するという不具合を生じる。 With such a conventional marking device 3, it is possible to draw a crosshair on the ceiling surface, but only a vertical line is drawn on the wall surface, and it is not possible to cope with the case where a crosshair line needs to be drawn on the wall surface. There is a defect. Further, the applicant of the present application proposed a marking-out device capable of drawing a spot on the wall surface and rotating the protection tube to set two points in the horizontal direction on the wall surface. There is a problem in this point because the horizon cannot be drawn. The applicant of the present application has further proposed a marking device that draws a crosshair on the wall surface to draw a spot on the ceiling surface. However, if a crosshair wire needs to be drawn on both the ceiling surface and the wall surface, the ceiling surface It is necessary to use both the marking device that draws a crosshair and the marking device that draws a crosshair on this wall surface, which requires a great deal of time and labor for positioning both devices, and the configuration required for marking is large. It causes a problem that it becomes.
