Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ruler for drafting, and particularly to a right-angle ruler that can be suitably used for drawing parallel lines in floor plans and the like.

Conventional technology and its problems Conventionally, a right-angle ruler consisting of a pair of long rulers is well known as a ruler used for floor plans, etc., which is placed on the top surface of a drawing board and moved in the X-axis direction or Y-axis direction. However, in drawings such as floor plans, it is necessary to draw many parallel lines of the same width, such as wall thickness or tatami width. I have a request.

However, with the conventional general-purpose square ruler mentioned above, it is necessary to match the thickness and width to the scale marked on the ruler each time and draw parallel lines of equal width while checking, which is very time-consuming and difficult to work with, and takes a long time to complete the drawing. It takes time and tends to lead to incorrect line drawings.

Purpose of the invention The present invention was made to solve the above problems, and it is possible to set the wall thickness and the interval between the tatami widths in advance in each of the X-axis and Y-axis directions on the paper, and to change the set interval on the same X-axis. It is an object of the present invention to provide a right angle ruler that can be used repeatedly to draw parallel lines at equal intervals in the direction or the Y-axis direction.

Structure of the Device As a means for achieving the above object, the present invention provides the right angle ruler with a child ruler extending parallel to the inner ruler edge of each parent ruler constituting the right angle ruler, with each child ruler attached to both ends of the ruler. A master ruler that is capable of sliding independently and stably against the master ruler through the guidance of a slide ruler that is perpendicular to the master ruler and child ruler provided, and that is affixed in accordance with the scale provided on the slide ruler and a certain agreement set forth below. The parallel distance between the inner ruler edge of the child ruler and the inner ruler edge of the parent ruler in the same X-axis and Y-axis directions can be freely set by matching with the indicated line of By moving the ruler together in the X-axis or Y-axis direction, it is possible to draw parallel lines at equal intervals at predetermined positions on the paper surface for wall thickness, tatami width, structural members, etc.

Embodiments of the invention Examples of the invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 and 1' indicate a master ruler, 2 and 2' indicate a child ruler, and 3 and 3' indicate a sliding ruler.

As shown in FIG. 1, the master rulers 1 and 1' are arranged at right angles by a forked arm or the like, and the child ruler 2 is placed parallel to the inner edge 4 of the master ruler 1 on the inner side of the master ruler 1'. A guide ruler 2' is placed on each ruler edge 4'.

A pair of slide rulers 3 are attached to both ends of the child ruler 2.
, and attach one end of each slide ruler 3 to the child ruler 2.
At the same time, the other end is extended perpendicularly to the upper surface of the master ruler 1 and inserted into the slide guide 6 provided on the upper surface of the master ruler 1, using the slide guide 6 as a guide. The child ruler 2 can be moved in parallel to the ruler 1 in the directions of approaching and moving away from it.

A set screw 7 is provided on both or one free end of the slide ruler 3, and the set screw 7 can be moved forward and backward toward the master ruler 1, and by screwing it toward the master ruler 1, the screw tip is brought into contact with the master ruler 1. The parallel movement position of the child ruler 2 is fixed, and the set screw 7 is loosened to allow the child ruler 2 to move in parallel.

The child ruler 2 and the slide ruler 3 can be fixed to the master ruler 1 by, for example, increasing the frictional resistance of the sliding surfaces of the slide guide 6 and the slide ruler 3 appropriately.

The set screw 7 also serves to prevent the slide ruler 3 from coming off. Furthermore, by removing the set screw 7, the child ruler 2 can be removed or attached together with the slide ruler 3.

Similarly, the other child ruler 2' is equipped with a pair of slide rulers 3', one end of each slide ruler 3' is fixed to the end of the child ruler 2' with a screw 8', and the other end is attached to the main ruler 1'. The child ruler 2' extends perpendicularly to the upper surface, and is movable parallel to the parent ruler 1' in a direction toward and away from the parent ruler 1' via a slide guide 6' provided on the upper surface of the parent ruler 1'.

Further, the structure is such that the position of the child ruler 2' is fixed in parallel with respect to the parent ruler 1' by a locking screw 7' provided on both or one free end of the slide ruler 3', and the translational movement of the child ruler 2' is permitted.

The mutually adjacent end faces of each sub-ruler 2, 2' are inclined surfaces 11, 11' of 45 degrees, and are constructed so as to come into contact with each other when the sub-ruler 2, 2' is moved beyond the final point.

The width of the child ruler is the unit dimension of the floor plan design (1 room =
1.8m) scale width. It is manufactured to a width of 1.8cm corresponding to 1/100th scale or 0.9cm corresponding to 3rd scale.

The inner ruler edges 5, 5' of the child rulers 2, 2' and the inner ruler edges 4, 4 of the master rulers 1, 1' correspond to the amount of parallel movement of each child ruler 2, 2' to the slide rulers 3, 3'. Attach scales 9 and 9' to read the distance between the two.

The main ruler 1 along the other slide ruler 3, 3',
Inner ruler edges 4, 4' of parent ruler 1, 1' on the surface of 1'
from the inner ruler edges 4, 4' of the parent rulers 1, 1'.
The intervals P and P' of 0 and 10' are made equal to the scale intervals S and S' of the scale starting points 12 and 12' from the inner ruler edges 5 and 5' of the child rulers 2 and 2'.

That is, as shown in Figure 2A, the master rulers 1, 1'
When the inner ruler edges 4, 4' of the child rulers 2, 2' are aligned with the inner ruler edges 5, 5' of the child rulers 2, 2', the indicated line interval P,
P' matches the scale intervals S and S'.

Place the square ruler configured as above on the top of the drawing board.
It is provided movably in the axial and Y-axis directions.

As shown in FIG. 2B, first, the slide ruler 3 moves the inner ruler edge 5 of the child ruler 2 from the inner ruler edge 4 of the parent ruler 1 in the state shown in FIG. 2A, and both The parallel spacing between the ruler edges 4 and 5 is set by matching the indicator line 10 with the scale 9. In this setting state, a line is drawn using the inner ruler edge 4 of the master ruler 1 and a line is drawn using the inner ruler edge 5 of the child ruler 2, thereby completing writing of a set of parallel lines A and B.

Next, as shown in Figure C, while keeping the slide ruler 3 fixed, that is, the set interval Z between the master ruler 1 and the child ruler 2
While holding , move it on the rail in the X-axis direction, and draw parallel lines C and D in the same manner as above.

In this way, by repeating the above operation to create parallel lines at the same interval as the set interval Z, a large number of sets of parallel lines can be easily and quickly drawn.

Effects of the Device As explained above, the present invention includes a pair of parent rulers arranged at right angles, with child rulers extending parallel to each other along each inner edge of the ruler. The slide ruler can be moved parallel to the ruler, and the distance between the parent ruler and the child ruler can be freely set using the guide action and ruler action of the sliding ruler. The interval between a set of parallel lines to be drawn with the ruler edge can be set accurately in advance, and multiple sets of parallel lines can be quickly and easily set by simply moving the set interval in the X-axis direction or Y-axis direction. It is possible to pull it freely.

In particular, according to the present invention, the parallel spacing between one master ruler and the child ruler and the parallel spacing between the other master ruler and the child ruler are set in advance, respectively, and parallel lines in the X direction are drawn at the parallel spacing of the former. By immediately drawing parallel lines in the Y direction at the latter parallel intervals, it is possible to draw a line that intersects the parallel line in the X direction and the parallel line in the Y direction at right angles very easily and quickly. For example, the drawing lines for wall thickness in floor plan design are of equal thickness and intersect at right angles in the X and Y directions, and the same is true for the drawing lines for tatami mats, etc., but according to the above-mentioned right angle ruler of the present invention, a pair of child rulers are used. By working together with the slide ruler and master ruler, it is possible to easily draw the above-mentioned cross-parallel lines in the X and Y directions of the wall thickness and tatami mats, significantly improving the workability of floor plan design, and also making it possible to draw lines at pre-set intervals. This has the advantage that the work can be carried out without fear of drawing mistakes or design mistakes by simply repeating the drawing process.

Furthermore, according to the present invention, when setting the interval using the scale attached to the slide ruler, "indication lines are attached to the surface of the master ruler along the slide ruler at a constant interval from the inner ruler edge of the master ruler, and The interval between the indication line from the inner ruler edge of the parent ruler and the interval between the starting point of the slide ruler's scale from the inner ruler edge of the child ruler are made equal widths. It is possible to accurately set the parallel spacing between the rulers, and it is also easy to read, allowing the above-mentioned XY parallel line drawing to be performed without any erroneous operation.
