Abstract

The invention provides a folding method of a triangular insert single sheet; the method comprises the steps: with solid lines as shearing lines and dotted lines as folding lines, taking a piece of paperboard, and drawing an isosceles trapezoid l1l3b1b5 with solid lines, wherein the ratio of an upper bottom edge l1l3 to the lower bottom edge b1b5 is 1 to 2, and the included angle of waists and the bottom edges is 45 degrees; then, respectively drawing three equal diversion points b2, b3 and b4 in the b1b5 line segment, drawing a center point l2 in the l1l3 line segment, connecting the l1 and the b2 with a dotted line, connecting the l2 and b3 with a dotted line, and connecting l3 and b4 with a dotted line, to form folding lines l1b2, l2b3 and l3b4; and finally, symmetrically drawing a graph having the completely same size and dimension as a drawn graph according to the folding line l1l3, labeling points a1, a2, a3, a4 and a5, and forming a folding plane graph of the triangular insert sheet. Three faces of the triangular insert single sheet each have an insertable opening, a folding method is simple, and artware with rich and diverse models can be prepared.

Description

A kind of triangle inserts the method for folding of monolithic

Technical field

The present invention relates toA kind of triangle inserts the method for folding of monolithic, particularly relate to a kind of three faces and all have and can be inserted into the triangle of opening and insert the method for folding of monolithic.

Background technology

Life neutral body paper folding works have brought unlimited convenience and enjoyment, and inserting penguin etc. such as triangle vase, triangle is all the most significant ornament.Insert the plane works done with triangle and mount house ornamentation, do some small-sized cell phone ornamental regards especially numerous.Although traditional triangle inserts the method for folding of monolithic disclosure on books or website, but, the handicraft model change that the open delta being available for inserting on only one of which direction is inserted produced by monolithic is simple.In order to improve above-mentioned deficiency, excite the creativity of client, imaginative power simultaneously, triangle assembling parts is utilized to become the more interesting works of any shape, the present invention is on the basis of traditional triangle inserts monolithic, do further improvement, provide that a kind of manufacture method is simple, it is more rich to produce handicraft model, change more various, the most all have and can be inserted into the triangle of opening and insert the method for folding of monolithic.

Summary of the invention

In order to overcome above-mentioned existing deficiency in prior art, the invention provides that a kind of manufacture method is simple, it is more rich to produce handicraft model, change more various, the most all have and can be inserted into the triangle of opening and insert the method for folding of monolithic.

The technical solution adopted for the present invention to solve the technical problems is:A kind of triangle inserts the method for folding of monolithic, solid line is for shearing line, and dotted line is fold line, it is characterized in that: first, takes a piece of paper plate, draws isosceles trapezoid l with solid line₁l₃b₁b₅, upper base l₁l₃With bottom b₁b₅Ratio be 1:2, the angle on waist and base is 45 °, secondly, at b₁b₅B is drawn respectively on line segment₂、b₃、b₄Three Along ents, at l₁l₃Midpoint l is drawn on line segment₂, with dotted line junction point l₁And b₂,l₂And b₃,l₃And b₄, constitute fold line l₁b_{2 ,}l₂b_{3 ,}l₃b₄, finally, with regard to fold line l₁l₃One, symmetrical picture and the identical figure of picture shape size dimension, a mark point a₁、a₂、a₃、a₄、a₅, constitute the folding plane of triangle inserted sheetFigure。

According to claim 1A kind of triangle inserts the method for folding of monolithic, it is characterized in that: step 1), by △ a₁a₂l_{1 ,}△b₁b₂l₁Along a₂b₂Axle fold inward 180 °, △ a₄a₅l_{3 ,}△b₄b₅l₃Along along a₄b₄Axle fold inward 180 °, respectively with △ a₁a₃l₁, △ b₂b₃l₁,△a₄a₅l₃,△b₄b₅l₃Overlap, form a foursquare plane；Step 2), by intersection respectively along line segment a₃l₁, l₁b_{3 ,}a₃l₃,b₃l₃Inwardly fold toward center, form the rhombus of isosceles；Step 3), by △ l₁b₃l₃Along line segment l₁l₃Turned-out turnover 180 °, puts a₃With a b₃Overlap, form an isosceles right triangle；Step 4), isosceles right triangle, along folding substantially symmetrical about its central axis, symmetric part coincidence of a folding, defines one three triangles all having socket and inserts.

The beneficial effect of the technical program is by above-mentioned measure, create and have the advantages that: the triangle of improvement is inserted monolithic and the most all had insertable open design, its method for folding is simple, it is more rich to produce handicraft model, change more various, as can be seen here, the present invention compared with prior art, has substantive distinguishing features and technological progress, and its beneficial effect implemented also is apparent from.

Detailed description of the invention

Below in conjunction withAccompanying drawingThe method for folding that triangle of the present invention is inserted monolithic further illustrates.

Embodiment:A kind of triangle inserts the method for folding of monolithic, it is characterized in that: first, take a piece of paper plate, draw isosceles trapezoid l with solid line₁l₃b₁b₅, upper base l₁l₃With bottom b₁b₅Ratio be 1:2, the angle on waist and base is 45 °, secondly, at b₁b₅B is drawn respectively on line segment₂、b₃、b₄Three Along ents, at l₁l₃Midpoint l is drawn on line segment₂, with dotted line junction point l₁And b₂,l₂And b₃,l₃And b₄, constitute line segment l₁b_{2 ,}l₂b_{3 ,}l₃b₄, finally, with regard to straight line l₁l₃One, symmetrical picture and the identical figure of picture shape size dimension, a mark point a₁、a₂、a₃、a₄、a₅, constitute the folding plane of triangle inserted sheetFigure。

According to claim 1A kind of triangle inserts the method for folding of monolithic, it is characterized in that: step 1) and by △ a₁a₂l_{1 ,}△b₁b₂l₁Along a₂b₂Axle fold inward 180 °, △ a₄a₅l_{3 ,}△b₄b₅l₃Along along a₄b₄Axle fold inward 180 °, respectively with △ a₁a₃l₁, △ b₂b₃l₁,△a₄a₅l₃,△b₄b₅l₃Overlap, form a foursquare plane；Step 2), by intersection respectively along line segment a₃l₁, l₁b_{3 ,}a₃l₃,b₃l₃Inwardly fold toward center, form the rhombus of isosceles；Step 3), by △ l₁b₃l₃Along line segment l₁l₃Turned-out turnover 180 °, puts a₃With a b₃Overlap, form an isosceles right triangle；Step 4), isosceles right triangle, along folding substantially symmetrical about its central axis, symmetric part coincidence of a folding, defines one three triangles all having socket and inserts.

The above, the triangle of improvement is inserted monolithic and is the most all had insertable open design, and its method for folding is simple, it is more rich to produce handicraft model, changes more various, and the above is not to thisInventionMake any pro forma restriction, on the premise of without departing from the technical scheme described in claim, also have other variant and remodeling.
