Description

  The present invention relates to a scribing device suitable for drawing a scribing line at a constant distance from a wall surface on a high surface such as a ceiling.

  Insulation material is laid on the ceiling during the interior work of apartments such as condominiums. At that time, a marking line is often drawn to perform the positioning. Since the ceiling cannot be reached by the height of a person, two workers have conventionally climbed on a stepladder and repeatedly applied a scribing line by hitting a thread soaked in an inkwell on the ceiling. It is not preferable from the viewpoint of work efficiency to repeat the stepping up and down of the stepladder and the drawing of the marking line in the inkwell, and it is not preferable from the viewpoint of the safety of the worker. In addition, there is a problem in that the marking line drawn by the ink jar has to be repeatedly performed by dividing the section, and the accuracy, that is, the marking line may not be drawn as a straight line when viewed as a whole. It was

  As a work for drawing a marking line on the ceiling, there is known a scribe device for attaching a lighting fixture and simply drawing a mounting hole of the lighting fixture (Patent Document 1).

  However, with the scribe device described in Patent Document 1, only a scribe line can be drawn in a narrow range centering on a point on the ceiling, and a scribe line that is continuous at a certain distance from the wall surface. Can not be drawn.

  Therefore, in the present invention, it is possible to accurately and easily draw a marking line at a position apart from a fixed reference surface such as a wall surface by a fixed distance with respect to a surface existing at a high place such as a floor surface or a ground surface. An object is to provide a scribing device.

  The above-mentioned problem is that the supporting rod, the marking material supporting member mounted on the end portion of the supporting rod and capable of fixing the marking material, and the length mounted on the supporting rod and longer than the width of the supporting rod. It is possible to solve the problem by the scribing device having at least both ends in the longitudinal direction thereof and at least support rod supporting members that can be made to exist outside the width of the support rod.

  The present invention also provides various improved aspects.

  According to the present invention, even if the surface is located at a high place such as a floor or a ceiling away from the ground surface, a marking line can be accurately and easily located at a position apart from a certain reference plane such as a wall surface. Can be delineated.

It is a figure which shows the other aspect different from FIG. 1 of the scribe device which concerns on this invention. It is a figure which shows the aspect of the scribe device which concerns on the invention of this invention with which the scale was added.

  The present invention will be described in detail with reference to the drawings. However, the present invention should not be construed as being limited to the embodiments shown in the drawings.

  FIG. 1 shows one embodiment of the scribing device of the present invention. The scribing device of the present invention includes a support rod 1, a marking material support member 2 mounted on an end portion of the support rod and capable of fixing a marking material 3, and a width of the support rod mounted on the support rod. It has a longer length, and both ends in the longitudinal direction thereof have a support rod support member 4 which can be present outside the width of the support rod.

  In the invention of the present invention, the material constituting each part such as the support rod 1, the marking material support member 2 and the support rod support member 4 is not particularly limited as long as it has practical strength. it can. Examples thereof include metallic materials such as aluminum, magnesium and iron and alloys of these with other metals, wood, and hard plastics. Among them, it is preferable to use an aluminum alloy or magnesium alloy, which has a small specific gravity and is resistant to rust, and stainless steel is preferably used in terms of cost. Further, as long as the function as a scribing device is not impaired, a hollow one may be used for weight reduction.

  The support rod 1 plays a role of supporting the marking material support member 2 and also a role of supplementing a height to a surface to be drawn such as a ceiling. By having the end of the support rod 1 on the side opposite to the side where the marking material support member 2 is provided, the operator can perform drawing work even on the surface such as the floor or the ceiling away from the ground surface. it can. An anti-slip tool or the like for making the grip easy and reliable can be appropriately attached to the location. Although the support rod 1 may be in a monolithic form, it may be in a stretchable form by inserting another support rod member 1b into the hollow member 1a as shown in FIG. With such a configuration, the support rod 1 can be housed compactly, which is advantageous in carrying, and the length of the support rod 1 can be easily adjusted. A fixing member for fixing or releasing the hollow support rod member 1a and the other support rod member 1b is not shown, but any screw or lever may be used as long as it has a fixing and releasing action. It can be used without particular limitation, such as fixing with a lever-type fixing tool that presses a fixing member using the principle.

  In the present invention, the term “end” does not mean the end in a strict sense, but means an area of several centimeters from the end and about 10 to 30 centimeters for the grip.

  The cross-sectional shape (outer shape) of the support rod 1 is not particularly limited, and may be circular, elliptical, or polygonal. From the standpoint of operability and workability, the support rod portion where the support rod support member and sliding member to be described later are mounted is parallel to a certain reference plane such as a wall surface along which the scribing device is swept. It is preferable that the support rod has a large surface, and that the portion of the support rod gripped by the operator is formed in a thickness or shape that is easy to hold. The portion of the support rod 1 to be gripped by the operator may have a structure such that it can be gripped with both hands like a handle.

  The marking material support member 2 is attached to the end portion of the support rod 1 so that the marking material can be fixed. There is no particular limitation on the means for mounting the support rod 1 on the end portion as long as the marking material support member 2 can be fixed to the extent that the marking line does not fluctuate when the marking line is drawn. For example, there are a mode in which the support bar 1 is fitted, a mode in which a fixing member is used for fixing, a mode in which a fixing member 5 as shown in FIG. Among them, as shown in FIG. 1, it can be bent so as to be overlapped with the support rod, and the aspect of fixing with the fixing member 5 is advantageous in accommodation when not in use, which is preferable. In the embodiment shown in FIG. 1, both ends of the fixing member 5 are connected to the supporting rod 1 and the marking material supporting member 2 with fixing members each having a rotation axis, and can be bent at the central portion thereof. Then, the expanded state can be fixed to fix the positional relationship between the support rod 1 and the marking material support member 2. In addition, the fixing member 5 may be prepared as a separate member, and when used, both ends of the fixing member 5 may be fixed by a fixing method such as fitting the supporting rod 1 and the marking material supporting member 2 at respective fixing positions. .

  The marking material fixing method / means is not particularly limited as long as the marking material can be fixed to the extent that the marking material does not move when the scribe line is drawn. For example, an aspect in which a surface of the marking material support member 2 opposite to a surface to be drawn, such as the ceiling, is perforated and the marking material is fitted into the hole (see FIG. 5), and as shown in FIGS. 1 and 4. In addition, the marking material holder base 2b having a groove formed on the surface facing the surface to be drawn, such as the ceiling, is configured to be slidable in the groove provided in the marking holder base 2b, and the marking material 3 is As an example of a configuration including the gripping marking material holder (marking material holder 2a), there is an aspect in which the marking holder 2a is fixed and used by a fixing material (not shown). This mode is preferable because the marking material 3 can be positioned at any position.

  Although FIG. 1 shows a mode in which the support rod 1 and the marking support member 2 are fixed in a positional relationship such that they are orthogonal to each other, the present invention is not limited to this mode, and a line such as a ceiling should be drawn. The angle formed by the support rod 1 and the marking support member 2 can be an obtuse angle depending on the circumstances such as the surface being inclined. For this purpose, the fixing member 6 connecting the supporting rod 1 and the marking material supporting member 2 shown in FIG. 1 is configured so that its length or the fixing position of the supporting rod 1 or the marking material supporting member 2 can be adjusted. It is desirable that The present invention does not exclude a mode in which the angle formed by the support rod 1 and the marking support member 2 is an acute angle.

  The marking material 3 that can be used in the present invention is not particularly limited in its form and means as long as it can be drawn on a surface to be drawn such as a ceiling, and pencils, chalks, felt pens, ballpoint pens, nozzles, and ink from nozzles. Means for discharging, a laser marking machine and the like can be mentioned. If the surface to be drawn, such as the ceiling, may be damaged, it may be engraved with a needle and drawn. Among them, it is convenient to use a pencil, chalk, or felt pen.

  The scribe device according to the present invention is preferably provided with scales on the support rod 1 and / or the marking material support member 2 (see FIG. 6). The operator can easily draw a marking line by using the scale.

  The scribing device according to the present invention is mounted on the support rod 1 and has a length longer than the width of the support rod, and both ends in the longitudinal direction thereof may be outside the width of the support rod. The supporting rod supporting member 4 is provided. As shown in FIG. 1, the support rod support member 4 is unfolded at the time of use and is swept along the scribe device along a plane parallel to a certain reference plane such as a wall surface, and when drawing, The support bar 1 rotates to prevent the wire drawing from deviating from a certain distance from a certain reference plane such as the wall surface. That is, with the support rod 1 alone, a portion contacting a constant reference surface such as a wall surface of a scribing device may be a point contact or a contact with an extremely narrow surface so that stable drawing can be achieved. However, by using the support rod support member 4, it is possible to realize a wide surface contact or a point contact with a wider width in the sweep direction than three-point support, and it is possible to draw a stable marking line. And

  From this point of view, it is preferable that the length of the support rod support member 4 is longer, that is, the end portion of the support rod support member 4 can be present at a position farther outside than the width of the support rod. On the other hand, if the length is too long, the workability may be impaired. Therefore, it is preferable that the length of the support rod support member 4 be 1/3 or less of the length of the support rod.

  In the present invention, the support rod support member 4 is preferably rotatable about a support rod-shaped point as shown in FIGS. 1 and 3. By being rotatable, the housing can be made compact by rotating and fixing it to a position along the support rod 1 when not in use. In addition, the scribing device of the present invention can be used by attaching the support rod support member as a separate body and mounting it at the time of use, or by fixing the support rod support member on the support rod in advance. I don't mind. Further, it is preferable that the support rod support member 4 can be fixed when the support rod support member 4 is rotatable around a support rod-shaped point. The fixing means is not particularly limited as long as the support rod supporting member 4 can be fixed, and means such as screws and fitting fixtures can be used. Further, the fixed position after being rotated is not necessarily limited to the position where the support rod support member 4 and the support rod 1 are orthogonal to each other, and an arbitrary angle may be given depending on workability and operability. It can be fixed.

  The place on the support rod 1 where the support rod support member 4 is mounted can be arbitrarily set according to workability and operability. In order to facilitate storage when not in use, a region between the center of the support rod 1 and the marking material support member 2 is about 1/2 of the length of the support rod 1, preferably about 1/3. It is preferable that

  In addition, when the support rod support member 4 is rotatable about a support rod-shaped point as shown in FIGS. 1 and 3, the thickness of the support rod 1 (1b) is set to be smaller than that of the support rod support member 4. It is advantageous to make the support rod support member 4 thin in the rotation range by the thickness of the support rod support member 4 because it can be accommodated in the support rod 1 (1a) at the time of accommodation.

  Further, in the present invention, when the scribe device is swept along a constant reference surface such as a wall surface to draw a line smoothly, a smooth drawing can be performed. Therefore, as shown in FIG. And a sliding member (6a to 6d in FIG. 1) which is mounted at least at both ends of the support rod supporting member 4 and is slidably arranged at the same time in contact with a constant reference surface such as a wall surface. It is desirable to have 4 locations). The sliding member is not particularly limited as long as it can reduce the frictional force from a constant reference surface such as a wall surface, and static frictional force reduction such as fluororesin film, fluororesin fiber felt, ceramic chip, etc. Means may be mentioned, but it is preferable to use a dynamic friction force reducing means, for example, a caster, particularly a ball caster as shown in FIG. The farther the mounting positions of the sliding members are, the larger the width and length of the polygon obtained by connecting the points that are in point contact with each other are preferable. The distance between the individual sliding members is preferably 10 cm or more, more preferably 20 cm or more, and if possible, 30 cm or more. The upper limit is not particularly limited as long as operability is not hindered, but it is obvious that the upper limit is restricted by the length of the support rod 1 and the length of the support rod support member 4.

  Further, as shown in FIG. 1, two or more sliding members are mounted on the support rod 1 and two or more on the support rod support member 4, and a line connecting the sliding members on the support rod 1 is used. It is preferable to mount the support rod so that the lines connecting the sliding members on the support member 4 intersect with each other. By mounting the sliding member in this way, it is possible to obstruct the rotation of the support rod 1 in the horizontal direction and the rotation in the vertical direction at the time of sweeping, and to realize stable marking line drawing.

  Although not shown, a sliding member can be attached to the top of the supporting rod 1 so as to face the surface to be drawn such as the ceiling. By doing so, more stable drawing can be performed. Becomes At this time, it is preferable that the tip of the sliding member is aligned with the tip position of the marking material with reference to the horizontal plane, or the position does not exceed the tip.
