Angulation drawing instruments and the set square, the ruler that utilize the angulation drawing instruments to make

The invention belongs to the stationery manufacture technology field.

Present protractor, set square, the ruler of producing, owing to will not be used for the scale of angulation or the edge line that coincides with utensil of scale mark system on the utensil traditionally, also be not marked with the scale of gauge length at such edge line, thereby for angulation, particularly for picture, very inconvenient part is arranged, as draw an angle and the length of side thereof, often to pass through several procedures, even to use protractor, set square or ruler simultaneously, sometimes use a set square not enough, be with two set squares, not only time-consuming but also take material.In recent years, though some comrade has worked out some innovation and creation about protractor, set square or ruler, 87102127), utility model as invention: a kind of protractor (application number:: general-purpose set square (application number: 86206443), in fact all not too easy to addressing this problem.

The purpose of this invention is to provide a kind of utensil of not only being convenient to angulation but also being convenient to draw, and on this basis, some further are provided set square, the ruler of making of the angulation drawing instruments or are referred to as multi-functional triangular ruler, ruler with angulation drawing instruments function.

The angulation drawing instruments that the present invention is designed, its shape can be similar to (comprising thickness) shape (comprising shape that is similar to 0 degree～180 degree semicircular protractors and the shape that is similar to 0 degree～90 degree quadrant protractors) of protractor, the shape (shape and non-isoceles triangle chi and other the leg-of-mutton shape that comprise the isoceles triangle chi) of set square, the shape of ruler, also can be designed to trapezoidal, fan-shaped, arc, rectangle or other polygon-shaped (thickness can be similar to the thickness of set square, protractor or ruler).These are called on the utensil of angulation drawing instruments, the amount of having the scale or the scale mark at (or metering, as follows) angle.Its scale or scale mark can be similar on the common protractor.What of scale or scale mark, can resemble on the common protractor have many, also can have only seldom several (bars), as have only several angles commonly used, as 0 degree, 30 degree, 45 degree, 60 degree, the scale or the scale mark of 90 degree, these that have on the angulation drawing instruments can be used for angulation scale or scale mark, one (bar) or two (bar) or a plurality of (bar) scale or scale mark wherein will be arranged, have (bar) scale or scale mark in other words at least, for example the scale of 0 degree or 90 degree or 120 degree or 180 degree or scale mark (also comprise 0 degree and 90 degree, 0 degree and 120 degree scale or scale mark by that analogy), coincide with on the edge line of utensil or and overlap (this kind coincidence with the edge line of utensil, be with regard to its essential meaning, need not on the utensil edge line, can find described scale or scale mark).

The scale or the scale mark that are used for angulation, (comprise that 0 degree and 90 degree, 0 degree and 120 spend as its 0 degree or 90 degree or 120 degree or 180 degree, on the edge line of the utensil that scale or scale mark overlapped by that analogy), should the amount of having (or measure, as follows) scale or the scale mark of length, for example scale on the number axis of being said in the scale of the amount length on the ruler, the mathematics.On the described angulation drawing instruments these are positioned at a series of scales of the amount length on the utensil edge, can be initial point with the scale that is used for angulation on the utensil or the summit of scale mark institute angle, are marked.The summit of scale of talking about in the utility model that is used for angulation or scale mark institute angle, its scale mark is very short, even only is a point, and the utensil surface does not have angle, when can not find angle, the angle in can meaning by scale.

The summit that is used for the scale or the scale mark institute angle of angulation on the angulation drawing instruments utensil, can (comprise some angles or certain two angle at certain angle of utensil, when having two groups of angle measuring calibrations on the utensil, just can be respectively at two angles) the summit on, thereby make the summit at certain angle of the summit of the scale that is used to measure the angle on the utensil or scale mark institute angle and utensil, be in together on the point.

Can utilize angulation drawing instruments recited above to make multiple set square, ruler, for example with angulation drawing instruments and common set square combination, just can make the function of existing common set square, the set square that angulation drawing instruments function is arranged again, for another example, make up with angulation drawing instruments and multipurpose set square combination, ratio set square, also can make multipurpose set square, ratio set square have the function of angulation drawing instruments.In like manner, if make up and common ruler combination, also can make ruler have the function of angulation drawing instruments with the transparent substance making with angulation drawing instruments and common ruler.

Set square (or claiming set square), ruler with the making of angulation drawing instruments, its the most basic requirement is, on set square or ruler, scale or scale mark with angulation, scale that wherein has or scale mark, or have (bar) scale or scale mark at least, for example 0 degree or 90 degree or 120 degree or 180 are spent (comprising that also 0 degree and 90 degree, 0 degree and 120 degree are by that analogy) scale or scale mark, coincide with on the edge line of set square or ruler, or overlap with the edge line of set square or ruler.

Set square, ruler with the making of angulation drawing instruments, the scale or the scale mark that are used for angulation, for example on the edge line of the set square that scale or scale mark overlapped of its 0 degree or 90 degree or 120 degree or 180 degree (comprise 0 degree and 90 degree, 0 degree and 120 spend by that analogy) or ruler, scale or scale mark that should the amount of having length.Described these are positioned at a series of scales of the amount length on set square or the ruler edge line, can be initial point with the scale that is used for angulation on set square or the ruler or the summit of scale mark institute angle.

With set square, the ruler that the angulation drawing instruments are made, be used for the summit of the scale or the scale mark institute angle of angulation on its set square, the ruler, can be at certain angle (comprising some angles or certain two angle) of set square or ruler, for example on the summit at right angle.

The materials of angulation drawing instruments recited above, set square, ruler can be transparent substances, as transparent plastic, organic glass, also can be non-transparent substances, as wood, metal.On the angulation drawing instruments or set square or ruler made of transparent substance, the edge line that can have expression and certain bar straight flange of this utensil is apart from different a series of scales (comprising point, line), or has perpendicular to the edge line of this utensil bar straight flange and indicate the straight line of length scale.

Edge line with expression and certain bar straight flange of this utensil is apart from different a series of scales or have edge line perpendicular to certain bar straight flange, and indicate the straight line of length scale, on same utensil, scale preferably has more than two groups, straight line (comprises available edge line perpendicular to certain bar straight flange, and indicate the other edge line of the utensil of length scale, and also as straight line like this) preferably have more than two.In addition, making is similar to the angulation drawing instruments of 0 degree～180 degree semicircular protractor shapes, scale or the scale mark that also can not emphasize its 0 degree and 180 degree overlap with the edge line of utensil, as long as make the straight flange of the utensil at 0 degree of angulation on the utensil and the 180 scale mark places of spending, on its edge, the scale of the amount of having length also can.

In order to make angulation drawing instruments of the present invention, set square or ruler more practical, also can consciously a certain straight flange of these utensils be made similar standard rule (as 30 centimetres of chis) or pass student length or appearance with chi (as 15 centimetres or 20 centimetres of chis).

Angulation drawing instruments of the present invention not only angulation convenient (for example common protractor can not be measured the length of side at angle and angle simultaneously, this product can be measured simultaneously, and it is also convenient when the short or long angle of the spirogram shape length of side, because this product both can make full use of angle measuring calibration, also can make full use of the side length lines of the ruler that overlaps with angle measuring calibration.), draw convenient (seeing embodiment), and, the angulation drawing instruments ask to join one long broadside greatly with protractor diameter or radius because can lacking one than present protractor, maybe can be that not enough hemicycle is big, littler than semicircular protractor, or angulation drawing instruments can have the function of two set squares of present composition one cover simultaneously, or can have the function that two set squares add a protractor in addition simultaneously, or can have ruler simultaneously, set square, the function of protractor, other adds the function that can utilize the polar coordinates principle to draw, this facilitates the work of saving when drawing and is country, enterprise saves a large amount of making rulers, set square, the raw material of protractor wherein particularly can be saved expensive plastics, organic glass.

Fig. 1 is the illustration of the angulation drawing instruments of 0 degree～120 degree polygonal shapes, on the scales of its 0 degree and 120 degree or the edge line that scale mark all coincides with utensil (also can only make wherein 0 spend the edge line that scale mark coincides with utensil, and spend the limit that does not have angle measuring calibration that the scale marks next door still keeps a similar common protractor 120), on the edge line of 0 straight flange that scale or scale mark overlapped of spending, the scale with gauge length.Three straight lines perpendicular to a certain straight flange of angulation drawing instruments are arranged among the figure, all indicate above length or expression and straight flange distance scale (as among the figure 1., 2. shown in).

Fig. 2 is the illustration that is similar to the angulation drawing instruments of set square shape, also can think the illustration with the set square of angulation drawing instruments making.Indicate the scale or the scale mark at metering angle at the position, right angle of utensil, emphasis has been marked the scale marks of angle commonly used 30 degree, 45 degree, 60 degree among Fig. 2, and its 0 degree and 90 is spent scales or scale mark and coincided with on the edge line on both sides, utensil right angle or with the edge line on both sides, utensil right angle and overlap.The scale of both sides, the utensil right angle amount of indicating length, its length scale from the utensil right angle, also be that the vertex that utensil is used for angle measuring calibration institute angle begins mark.On the hypotenuse of set square, have hypotenuse edge line perpendicular to set square, and indicate the length scale (as 1., 2. shown in) straight line.

Fig. 3 is the illustration that is similar to the angulation drawing instruments of ruler shape, also can think the illustration with the ruler of angulation drawing instruments making.A footmark that centers on the left end of figure has the scale of angulation, its 0 degree and 90 degree scales coincide with on the edge line of utensil, and be marked with the scale of gauge length at this edge line, on two straight lines perpendicular to two straight flange edge lines of ruler among the figure, indicate gauge length scale (as 1., 2. shown in).For the length scale of avoiding angle measuring calibration and both sides, utensil right angle too much occurs simultaneously together, angle measuring calibration is not signed in the summit of its angle among the figure.

This product uses comparatively convenient.If the present invention made have the ruler function, the multifunctional product of two set square functions and protractor function, use and just seem more convenient.Now with one have ruler function, two set square functions and a protractor function be similar to the set square shape, as the angulation drawing instruments of accompanying drawing 2, the angle of drawing one 100 degree is an example, is illustrated.Draw straight line earlier, the scale mark that is expressed as 80 degree angles on the angulation drawing instruments (there is not scale mark among the figure, can will be considered as a line between 80 degree scales and the summit, right angle, and look this line be 80 the degree scale marks), aim at the straight line of having drawn, from the vertex of angulation drawing instruments institute angle, be 80 degree along the folded angle of the 0 degree straight line that scale mark drew and the straight line that has drawn earlier at utensil straight flange edge, its supplementary angle is 100 degree.Draw an angle again and be 40 degree, the length of side is respectively 3 centimetres, 4 centimetres angle and is illustrated.Draw from left to right earlier one long be 4 centimetres straight line, when again the degree of 40 on angulation drawing instruments scale mark being aimed at the straight line of having drawn, the summit of the scale institute angle of angulation on the angulation drawing instruments is aimed at the left end point of straight line, 0 degree scale mark from end points along the straight flange edge, straight line to one 3 centimetres in upper right side picture, the scale that gauge length is arranged on the utensil edge need not change the length that ruler can be held line like this, the angle that will draw of just having drawn.Can also utilize on different a series of scales of the edge line distance of expression and certain bar straight flange of this utensil on the angulation drawing instruments or the utensil perpendicular to the edge line of a certain straight flange and have the length scale (as mark in the accompanying drawing for 1., 2. scale) straight line draw parallel lines, its technique of painting is: with scale or the scale mark of desired expression on the utensil of the much distances of straight flange, find and aim at the straight line of having drawn by transparent substance, along the drawn straight line of the straight flange edge line of utensil, be being parallel to of the picture that requires to draw PAR.In order to ensure the straight line that will draw and the straight line parallel of having drawn, make two rectilineal intervals from equating, when drawing long parallel lines, the expression on the adjusting to a line utensil that preferably will draw and utensil straight flange apart from identical two scale marks such as the accompanying drawing 1. and two points on two scale marks 2. going up.Draw parallel lines, regular meeting runs into often at picture, picture angle.
