Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking device for marking on a ceiling, a wall surface or the like.

[0002]

2. Description of the Related Art As a conventional device of this type, a marking tool, which is one of carpentry tools, is known. This marking-out tool has a marking jar and a drawing-out free drawing thread, and the drawing-out is carried out by repelling the drawing-out thread of an arbitrary length to draw a line on the work surface. This marking tool can be easily used if the work surface is the floor surface, but the work surface is, for example, a ceiling surface (specifically, a pseudo ceiling surface called a "discard tension board").
However, it takes a lot of time and effort to provide a marking surface for attaching the cooler. In this case, first draw a quadrangle corresponding to the size of the cooler on the floor with a marking tool, and use the quadrangle marked on this floor as a reference to match the necessary intersection points (four corners) on the line of the quadrangle. Either "hang" from the ceiling side and mark the corresponding position on the ceiling side and draw a line between the two points with a marking tool, or reverse from the above intersection points (four corners) on the floor surface. The work of irradiating a beam called a beam on the ceiling to give a mark called a "beam point" to the ceiling and drawing a line between the two points with a marking tool.

For this reason, in the subsequent work in which the ceiling surface is marked with "pitch" or "beam point", the height between the marked two points is increased by using a marking tool and a stepladder or the like. Since the work is to draw a wire in a place, the work against the gravity must be continued for a considerable time, which is a troublesome work.

[0004]

Therefore, it has been desired to develop an apparatus that can easily perform the work for marking high places after marking the ceiling, wall surface, etc.

[0005]

According to the present invention, there is provided a support rod having a black ink pot and a black ink reel so that the black yarn can be drawn out from the front end, and a plurality of support rods which are combined with the front end of the support rod at arbitrary positions on a plane. No. 4 needles can be positioned, and the ink thread extending from the support rod side is stretched between the point needles to form a marking surface having a desired size and shape, and the stretched ink thread The marking means for the ceiling, the wall surface, etc. is constituted by the means for flipping.

As the ink thread overhanging means, there is provided a scale plate having a point needle locking hole at the intersection of a plurality of vertical and horizontal scale lines formed on a transparent / translucent material, and this point needle engaging member. It is provided with a point needle that is detachably locked in the stop hole.

Further, as the ink thread overhanging means, instead of the above-mentioned combination of the scale plate and the point needle, a scale plate formed of a transparent / translucent material and provided with an angle adjusting scale, and movable and positionable. It may be formed by two folding arms having slider-shaped point needles with adjustable crossing angles.

[0008]

By using the ink thread overhanging means, a plurality of point needles are arranged at desired positions on a flat surface, assuming an ink drawing surface to be applied to a ceiling, a wall surface or the like in advance. Then, the ink thread is fed from the support rod side combined with the ink thread projecting means. The black thread reeled out from the black thread reel is inked with a black ink pot and stretched between the point needles to prepare a blackened surface of a desired size and shape. Using the marking-out device for the ceiling, wall surface, etc. prepared in this way, the central position for marking-out is given to the ceiling, wall surface, etc., for example, at the "beam point", and the tip of the support rod is positioned at this mark position. In the combined state, the ink thread overhanging means faces the ceiling, wall surface and the like. Therefore, if the black thread stretched around the point needle is flipped by an appropriate flipping means, a preset blacking surface can be applied to the ceiling, wall surface, etc. at once.

As the ink thread overhanging means, a scale plate having a point needle locking hole at the intersection of a plurality of vertical and horizontal scale lines formed of a transparent / translucent material on the upper surface, and this point needle locking When using a point needle that can be detachably locked in the hole, the point needle is locked at the intersection selected on the assumption of the marking surface to be applied to the ceiling, wall surface, etc. If it is stretched between the point needles, it can be easily prepared so as to form a marking surface of a desired size and shape. Then, only by flipping the black thread stretched between the point needles, the predetermined blacking operation can be performed as a floor operation instead of an aerial work.

Further, in place of the combination of the scale plate and the point needle as the ink thread overhanging means, a scale plate formed of a transparent / translucent material and provided with an angle adjusting scale, and a slider which can be moved and positioned freely. When using the one formed with two folding arms having cross-shaped point needles with adjustable crossing angles, the crossing angle of the two folding arms can be adjusted by utilizing the angle adjustment scale of the scale plate. Open the arm in a state similar to opening an umbrella, define the plane of the folding arm, then move and position the slider-shaped point needle, and stretch the ink thread between the point needles to obtain the desired size. It can be easily prepared so that the squeezed surface of the shape can be formed. Then, only by flipping the black thread stretched between the point needles, the predetermined blacking operation can be performed by the floor work instead of the high place work.
