[0005]

According to the straight ruler mounting means of the free parallel ruler according to the present invention, the scale mounting groove provided through the scale mounting plate along the longitudinal direction of the scale is provided over the entire length of the scale to be adjusted. By fitting the fixed member slidably, there is an effect that the scale can be fixed to the scale mounting plate in a length-adjustable manner.

According to the present invention, when the scale is mounted on the scale mounting plate, an arbitrary portion of the scale fixing member provided in the entire area where the length of the scale is to be adjusted is fixed to the scale fixing means of the scale mounting plate. Therefore, by selecting the fixing position, it is possible to freely adjust the length of the left, right, up and down projections with respect to the mounting plate of the scale.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. Reference numeral 1 denotes a scale according to the present invention, and a scale fixing member 2 is provided on the upper surface of the scale in the entire longitudinal direction of the scale. In the case of the embodiment, as shown in FIG. 3, the scale fixing member 2 is configured so that its cross section has an inverted trapezoidal shape. Reference numeral 3 denotes a fixing screw for attaching the fixing member 2 to the scales 1 provided at both ends of the scale fixing member 2.

Reference numeral 4 denotes a scale mounting plate. As scale fixing means for fixing the scale 1 on the drawing board 10 in a vertical direction and a horizontal direction so as to be orthogonal to each other, as shown in FIG. Are provided with an inverted trapezoidal scale mounting groove 5 which slidably fits. As shown in FIG. 2, the mounting groove 5 is provided through the scale mounting plate along the longitudinal direction of the scale 1, and in the case of the embodiment, the vertical and horizontal mounting grooves intersect. 6. The mounting groove 5 is rotated by the rotating operation.
A fixing screw means for fixing a scale fixing member 2 with a mounting groove 5 by press-fitting a conventionally known fixing member including an eccentric shaft or a cam member therein. The scale mounting groove 5 and the fixing screw means 6 constitute the scale fixing means of the present invention.

The scale fixing member 2 is not limited to the embodiment, but may be any member that is integrally provided along the longitudinal direction of the scale 1 for attaching the scale 1.
Similarly, the scale fixing means on the scale mounting member 4 side also
A configuration of a clamping type in which the scale fixing member 2 is movably clamped along the longitudinal direction of the scale 1 so as to be movable and fixed is also possible.

As shown in FIGS. 1 and 5, the scale mounting plate 4 is integrally fixed to a scale mounting base fixed to the lower end of a head shaft rotatably supported by the head support base 7, It is configured to rotate or move in parallel with the operation head 8 fixed to the upper end of the head shaft.

The head support base 7 is connected to a vertical cursor guided and moved by a vertical rail 9 on the drawing board 10 in FIG. 5, and the upper end of the vertical rail 9 extends along the upper side of the drawing board 10. Connected to a horizontal cursor that moves along the fixed horizontal rail 11.

Accordingly, the scale 1 can be freely translated and rotated on the drawing board 10 by holding the head portion 8 so as to be able to draw a line by measuring dimensions and angles along the scale 1. At this time, the fixing screw means 6 of the scale mounting plate 4 is loosened, and the scale 1 can be moved along the mounting groove 5 in the longitudinal direction as shown by a broken line in FIG. The drawing work can be advanced by setting the length and position.

[0013]

According to the straight ruler mounting means of the universal parallel ruler according to the present invention, the scale fixing means is attached to the scale mounting plate 4 to be rotated integrally with the operation head 8 of the universal parallel ruler.

The scale mounting plate 4 is provided so as to pass therethrough, and the scale

The length of the scale 1 passes through the scale mounting plate 4
By having the configuration provided on the scale 1, the scale 1 can penetrate through the scale mounting plate 4 and freely adjust the length of protrusion vertically and horizontally and can be fixed.
As shown in FIG. 1, the scale 1 projecting from the right side of the operation head 8 can be projected leftward without operating the operation head 8 by 180 ° rotation. The scale 1 can be made to protrude downward, which has the effect of making drafting work efficient. In addition, by changing the fixing position of the scale 1 with respect to the scale mounting plate 4 arbitrarily, it is possible to replace the scale with a scale having a different length. The length of projection of the scale 1 from the head portion can be variably set with one scale 1, and there is an effect that drawing work can be efficiently performed.

Further, since the scale 1 can penetrate through the scale mounting plate 4 and can be freely adjusted in length to protrude right and left and up and down and fixed, the operation head 8 does not need to be rotated by 180 ° and the operation head 8 can be rotated. There is an effect that the drafting operation can be efficiently performed with one scale 1 that simultaneously projects to the left and right sides or the upper and lower sides.
