Abstract

The utility model relates to a multi-purpose tailor ruler collecting the functions of rapid calculation, measurement, drawing the straight lines as well as the large and small curvature arcs of clothes sheets, etc. The multi-purpose tailor ruler is characterized in that the rim on one side of the two sides of the ruler is straight, while the rim on the other side is provided with a large and a small two arc-shaped curve bodies; the small curve body can also be arranged on the top of the straight side. The large and the small two curve bodies are respectively used for drawing the large and small curvature arcs of the clothes sheets. The upper and lower two sides on the straight side of the ruler body are respectively marked with size scales as well as fractions, indication arrows, reading numbers and scales for the rapid calculation of clothes cutting; consequently, the multi-purpose tailor ruler also has the functions of rapid calculation, measurement and drawing the straight lines of clothes sheets and ensures that the whole ruler collects multiple functions into integration.

Description

Multi-purpose tailor ruler

The utility model is that a kind of collection calculates drawing quickly, measures, draws purposes such as clothing sheet straight line and big or small camber camber line is the tailoring all-purpose instrument of one.

Usually people are in tailoring, all will calculate according to the fraction scale formula at each position of clothes (be called for short " cutting formula ", down with), also will find out the yardstick of asking after calculating the result on ruler; When drawing cutting figure, not only to measure and draw straight line, also will draw the camber camber line of clothing sheet with curved chi with ruler.So just will use several instruments usually, both inconvenient, overslaugh is increased work efficiency again.

For addressing this problem, past attempts has the people to do to inquire on ruler." the tailoring engineer's scale " in " engineer's scale garment cutting method " telecourse of doing in July, 1991, introduced as Guangxi TV station (it is said gain the national patent), and the cutting cloth that produce in the Guangdong that sale is early arranged on the market is bent chi, the two all has versatility, but also there are many defectives: one, the former line purposes of making an arc, only be applicable to and draw big camber camber line on the clothing sheet, and be not suitable for the little camber camber line of the system of drawing; Calculating and measure purposes quickly though the latter also has, all is chi to be unit of account, uses the people of metric system long measure inapplicable to custom.Two, the two chi body length that is used to measure is all too short, can not reduce ruler measure and rule the drawing in mobile number of times.Three, calculating quickly on the purposes, what the former adopted is the percentage method, and traditional fraction scale method that the whole society is generally continued to use is not suitable for; Though the latter adopts traditional fraction scale method, but representative fraction and reading that its chi face institute target various places cutting cloth is generally used always are very few, therefore all there is significant limitation in the two calculating quickly on the purposes: the former only is applicable to that the inventor writes and with the percentage method cutting book of chi collocation, the latter only is applicable to its place of production.For solve blanket calculate quickly etc. many with cutting cloth instrument problems, I had once designed＜patent No. is 88204369.2〉has and calculates, measures, draws " the tailoring speed-calculating ruler " of straight line purposes quickly, but this chi does not have the purposes of the line of making an arc, and is therefore using yet existence deficiency more.

The purpose of this utility model will provide a kind of advanced, blanket in China, and collection is calculated quickly, measured, draws purposes such as clothing sheet straight line and large and small camber camber line is the tailoring all-purpose instrument of one.

The utility model is achieved in that will make the dual-side edge of the plate of chi body, and it is straight to be processed into a side, and a side is large and small two cambers and bends body.Little curved body also can be located at a straight side roof part, and opposite side becomes a big curved body separately.Big curved body is suitable for drawing big camber camber line on the clothing sheet, and little curved body is suitable for drawing little camber camber line on the clothing sheet.In the straight side of chi body upper and lower surface, engrave respectively with centimetre or cun be the yardstick of unit.End in two sides yardstick starting point, put on tailoring formula in all parts of the country 8 kinds of marks generally commonly used respectively, and the arrow that is used to calculate quickly, reading, scale, make it both have the purposes of measuring and drawing straight line, have the blanket purposes of calculating quickly again, calculate, measure, draw multiple uses such as clothing sheet straight line and large and small camber camber line quickly thereby guarantee to make whole chi to realize integrating.

Advantage of the present utility model is: one, generally be suitable for (centimetre to be that also generally being applicable to of unit is external) in China; Two, have the drawing calculated quickly, measure, draw multiple uses such as clothing sheet straight line and large and small camber camber line; Three, be used to calculate quickly drawing cutting cloth, can make and calculate and find out the yardstick of asking quickly and once finish, than all soon several times of common any algorithms; Four, a chi has replaced three chis (being ruler, curved chi, speed-calculating ruler), has reduced cutting with the many troubles of instrument.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Figure one, figure two are that figure three is amplification views of figure two " A-A " section according to the many same chi bodies with tailor ruler that the utility model proposes plane of each one side up and down.

The details of the many concrete structures with tailor ruler that the utility model proposes below in conjunction with description of drawings and uses thereof usage: (annotate: below the figure number and the numbering of accompanying drawing appear, remove dated, all are numberings of figure two):

One, concrete structure.

Many main body dual-side edges 1. with tailor ruler be a side directly 2., opposite side be a big curved body 5. with a little curved body 8..8. little curved body also can be located at straight side top 2., and opposite side is a big curved body (seeing shown in figure one, figure two dotted lines) separately.The big curved body 5. mid point camber of the following 30cm section in top is 1.2-1.8cm deeply, and 30cm is linearly with next section.Little curved body is 8. long to be 8-12cm, and the mid point camber is 1.2-1.8cm deeply.In the main body side that 1. upper and lower surface is straight 2., all being carved with centimetre (or a cun) is the yardstick of unit.At an end of every yardstick starting point, all indicate four marks, one side is 1/2,1/3,1/4,1/10(figure one), another side is 1/5,1/6,1.5/10,2/10(figure two).In every each divides number average to have an arrow 4. to point to one to arrange the reading that the type clothing is commonly used according to quantity the size order of measuring radix is arranged, each reading bottom or a side, a scale (scale that has does not mark reading, can calculate between following from it two readings) is all arranged.In the 1. one side in the upper and lower surface of main body, be printed on " this chi is calculated directions for use quickly " 3..On every big curved body edge 5., all be carved with " drawing upper garment side seam, collar, sleeve sheet, trousers sheet shank both sides camber line " 6. printed words, 8. on the edge, all be carved with " drawing upper garment neckline, muffs, trousers sheet front and back cage door camber line " 7. printed words at little curved body.
