Description

  The present invention relates to a measuring tape for inking that can be used to mark a mark by linearly marking allocation dimensions at predetermined intervals by carpenters, masons, tilers, and the like.

Conventionally, when performing various types of work such as carpentry, masonry, tiler, etc., it is possible to save time and effort by setting various types of work along the marked reference line, such as allocation dimensions. There has been proposed an ink thread in which a portion not marked with black is provided or a portion marked with black is provided, and marks at predetermined intervals are graduated at the same time as inking the reference line (see Patent Document 1).
JP-A-8-178656

  Marks with such ink threads are inaccurate due to the scattering of the ink, and further, the ink threads expand or contract over time, or the borders are shifted due to the untouched and untouched parts, resulting in dimensional errors. There was an easy defect.

  The present invention provides a tape measure that eliminates the problems of the ink thread and can accurately mark marks at predetermined intervals at the same time as inking.

  The present invention is a tape measure for inking, characterized in that only the cutout holes provided at predetermined intervals on the tape surface are inked.

  By inking with the tape measure of the present invention as the underlay, the edges of the ink lines that are linearly inscribed in the cutout holes can be used as marks for the scales at predetermined intervals.

  In addition, since the uncut portion is covered and only the cut hole portion is inked, there is no blurring of the edge due to the scattering of the ink, and it is possible to reliably mark the marks at predetermined intervals with high accuracy.

  Furthermore, since the tape has almost no expansion / contraction or aging deterioration as compared with the yarn and no dimensional error occurs, the tape measure according to the present invention can be used for many years without degrading accuracy.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a form of a measuring tape for inking according to the present invention. 1 is a tape made of steel or plastic which is difficult to expand and contract, 2 is a cut-out hole provided at a predetermined interval on the tape surface, 3 is a hook for hooking, 4 is a tape having a length adjusting function, and a hook for hooking The connecting member 5 is a pin hole for piercing a pin, 6 is a tape winding portion, 7 is a tape winding handle, and 8 is a winding portion fixing pin.

  FIG. 2 (a) shows an example of a state in which the inking is performed using the inking tape measure of the present invention as an underlay. First, the hook 3 is hooked at the start point, the tape 2 is extended to a predetermined position, and the fixing pin 8 is inserted to fix the winding portion 6. Next, the chalcone 9 at the tip of the ink thread 10 is stabbed into the pin hole 5 at the tip of the tape 1, and the ink brush 11 is moved to pull out the ink thread 10 while pulling out the ink thread 10, along the substantially center of the cutout hole 2. After tensioning to the position, pick it up with your finger and play ink. FIG. 2B shows a mark 12 that is a scale indicated by a broken line that is marked by the ink marking of FIG. 2A.

  If the thickness of the tape 1 used as the underlay of the ink mark exceeds 0.35 mm, the end of the cutout hole 2 is not marked during the ink mark, and the edges of the ink line are blurred and the scale 12 cannot be drawn correctly. On the other hand, when the thickness is less than 0.1 mm, the strength is weak and the tape 1 is easily damaged. Accordingly, the thickness of the tape 1 is desirably in the range of 0.1 mm to 0.35 mm, and is preferably about 0.2 mm.

  The shape of the cut-out hole 2 is a cause of ink dimensional error due to blurring of the ink line or deviation from the axis unless the line segment intersecting with the longitudinal direction of the tape is vertical. Therefore, the edge of the ink line used as a mark is formed. It is necessary to make the line segment at least perpendicular to the longitudinal axis (ink thread) of the tape. Usually, it is good to make it a rectangle (including a square) having two sides perpendicular to the axis.

  In addition, since the longitudinal dimension of the cutout hole 2 is short and the tape 1 becomes thick, the edge of the cutout hole 2 becomes difficult to be drawn when inking, so the longitudinal dimension becomes longer as the thickness increases. When the thickness is 0.1 mm, it is necessary to be 10 mm or more, and when the thickness is 0.35 mm, it is necessary to be 30 mm or more.

  As for the width direction dimension of the cut-out hole 2, when the tape is stretched straight in indoor work, it is sufficient if it is 5 mm or more considering the deviation of the tape and the ink thread and the blurring of the ink thread. When the tape is distorted due to the influence of the above or the like, the cutout hole 2 may come off from the ink thread 10 and a broken line may not be drawn. On the other hand, if the remaining width of the cutout in the width direction of the tape becomes narrower, the strength is weak and breaks easily. For example, in the case of a generally used 25 mm tape width, the width of the cutout hole is set to about 10 mm, the width of the remaining cutout at both ends is set to about 7.5 mm, and when a wide tape of 30 mm is used, The width of the hole is preferably about 12 mm, and the width of the remaining cutout at both ends is preferably about 9 mm.

  When it is unavoidable that the tape width of the remaining cutout is 5 mm or less, it is desirable to take measures such as thickening both ends in the width direction of the tape 1 for reinforcement.

  When the tape 1 is distorted by wind or the like and it is difficult to work, the work is facilitated by inserting a pin into the intermediate pin hole 5 and temporarily fixing the tape.

  In addition, a plurality of rows of cutout holes 2 having different intervals are formed in parallel on the surface of the tape, and the interval between the hooks 3 and the cutout holes 2 can be adjusted by the connecting member 4 so that a plurality of marks can be accommodated at a predetermined interval. You can make a measuring tape for driving.

  Furthermore, when the predetermined interval is constant, by setting the longitudinal dimension of both the cutout hole and the non-cutout portion to the predetermined interval, both edges of the black line become marks and the number of cutout holes is halved. be able to.

Below, the rafter line indicating the position of the rafter 14 is shown as the position (the pedestrian line) where the pier is fixed to the roof surface on which the field surface 13 is formed using the ink measuring tape of the present invention as shown in FIG. An example of marking at the same time as inking will be described.
As for the form of the roof surface to be inked, (1) a state where nothing is attached to the field floor 13 (FIG. 3A), (2) a tile base 17 on which the roof tile is placed on the eaves 15 There are three states (Fig. 3 (b)) and (3) a state where the first row of plinths 19 for attaching the roof tiles (Fig. 3 (c)) is installed. Replace the one suitable for the form.

  In Fig.3 (a), the hook 16 for eaves hooks is used by hooking on the eaves edge 15 in the case of a roof surface form (1). In FIG.3 (b), the hook 18 for tiles is used by hooking on the tiles 17 in the case of the most general roof surface form (2). In FIG.3 (c), the hook 20 for hooks is hooked and used for the bridge 19 in the case of a roof surface form (3). These hooks 16, 18 and 20, when the distance from the first cut-out hole 2 of the tape is the roof surface form (1) and (2), are ascending foot dimensions (eave piers) according to the dimensions of the eaves tiles. In the case of the roof surface form (3), it is adjusted so as to have a climbing foot size (crosspiece size) according to the size of the roof tile, and is attached to the tape 1 by the connecting portion 4.

  The longitudinal dimension of the cutout hole 2 of the tape measure for the pier dimensions is larger than the generally used wide pier width of about 30 mm because the installation position of the pier is easy to be mistaken if the inked mark is hidden in the pier. It is desirable. Further, when the remaining cutout width in the longitudinal direction of the tape is shortened, the strength of the tape is weakened, and the broken portion of the broken line is hidden by the pier or becomes difficult to see when separated, so it is desirable to take 50 mm or more. In view of the above, since the crosspiece dimensions of the generally used roof tiles are about 225 mm to 280 mm, the longitudinal dimension of the cutout hole 2 is preferably in the range of 35 mm to 230 mm, and preferably about 100 mm.

  FIG. 4 shows a state in which the rafter line 21 is inked on the field ground using the inking tape measure of the present invention, and broken lines (rafter lines) are arranged in a mosaic pattern on the roof surface. Since the dotted line connecting the ridges in the direction parallel to the purlin becomes the virtual pier line 22 indicating the position where the pier is to be installed, the pedestal is laid out along the virtual pier line 22 without drawing the pedestal dimensions and drawing the pier line. be able to.

  Usually, the distance between the hook and the hole is taken with the reference of the hole 2 as the end on the hook 3 side. In this case, as shown in FIG. 4, the upper end of the broken line of the rafter line 21 (the purlin side) is the virtual pier. Used as a line. On the other hand, by setting the reference of the hole to the end opposite to the hook, the lower end of the broken line (eave side) can be used as a virtual pier line.

  The tape measure of the present invention is used as an underlay for inking for carpentry work, masonry work, tile work, etc., and at the same time, marks are made at predetermined intervals such as allocation dimensions. Used as a tool.
