Abstract

The device has sections (T) that are composed of rhombuses, triangles and trapeziums which change their size to form an object section having a conical shape. The rhombuses, triangles and trapeziums are connected with each other by stops comprising connections. The volume of an object is reduced, when forces (8, 9) are exerted in one direction. The object is unfolded, when forces (10, 11) are exerted along opposite directions.

Description

2873353 1

  The present invention relates to a device for reducing volumes, cube, rectangular parallelepiped, right prism, regular pyramid, regular pyramid trunk, cylinder, cone and the like of plastics, cardboard and other types.

  These forms are used in everyday life. They serve most often container, water can, drink can, storage box, goblet and others, all these objects and many others not mentioned are made in the form of the aforementioned volumes. But these volumes are all of a constant form. The user can use and transport them only in the form predefined by the manufacturer. So when they have used or transported one of these empty objects like cans or goblets or the like of the same type, accidents can occur during the transport, as crush them because they are empty. The user must find a bag as big as the volume to carry them. These objects can be overwritten during transport and will not return to their original forms. They will also lose their rigidities for some. Some manufacturers have designed a technique on some volumes that can compact to be thrown in the trash for recycling, but these compact objects are no longer reusable. The objects build in the form of the aforementioned volumes, are most often without handle which imposes on the user a very strong grip by the action of a constant force at the end of the fingers. The action of a lesser force can drag the object from the tips of the fingers. That's why some manufacturers bring some reliefs to their objects, to increase the adhesion.

  The device according to the invention overcomes all these disadvantages.

  It comprises in fact according to a first characteristic, a pre-folding technique consisting of trapezes, diamonds and triangles. This technique can be adapted to all the aforementioned volumes, to reduce all these volumes empty, for better transport and storage.

  The pre-folding technique by its reliefs makes it possible to increase the grip of the hands on the objects in the hands.

  To study the reduction technique it will be applied to a cup and the study will be done on a section (T).

  All forms made with this technique will consist of sections, to form an object. The sections will consist of triangles of triangles and trapezoids, which will change in size in a section of conical object. A cup will consist of sections (T), a bottom and a lid for some. The section (T) to be studied in FIG. 1 will be cut by a plane (P) which will divide the section (T) into two equal parts (H) and (B) such that the upper part (H) is the image of the lower part (B). And (P) the plane of section is the symmetry (I) of the two parts. A small rhombus (90) is divided into two isosceles triangles (2) and (3) by the symmetry (I). The isosceles triangle (3) has two identical edges (4) and (5). Such as the triangle (12) has the same stop (4) with the triangle (3). Hence the triangle (13) has a stop (14) with the triangle (12) and a stop (5) with the triangle (3).

  The stop (14) tends towards the inside of the cup as shown by the arrow (70) as shown in FIG.

  The triangle (2) image of the triangle (3) relative to the symmetry (I) also has two edges (6) and (7) identical. Such as the triangle (80) on the part (H) has the same stop (7) with the triangle (2). Hence the triangle (81) also has the same stop (82) with the triangle (80) and a stop (6) with the triangle (2). Part (B) is also composed of two identical triangles (20) and (25) composed of the same stop (26) such that the small base of the triangle (20) is the stop (33) of the triangle (12). ) and the triangle (25) image of the triangle (20) with respect to the stop (26), is the same stop (32) with the triangle (13).

  The stop (26) tends towards the inside of the cup as shown by the arrow (71). The set of triangles on the part (B) are touching such that the edges (26), (33), (14), (32) tend to return towards the inside of the cup.

  The triangles of the part (B) have their images on the portion (H) of the section, such that the stop (36) of the triangle (81) is also the edge of the triangle (40). Hence the stop (37) is also the stop of the triangle (41) which has the same stop (42) with the triangle (40). Such as the stop (82) tends to exit in the direction of the arrow (72).

  The triangles (40) and (41) of the part (H) are the images of the triangles (20) and (25) of the part (B) with respect to the symmetry (I), hence the triangles (80) and (81) of the part (H) are the images of the triangles (13) and (12) of the part (B) and the triangle (2) of the part (H) is the image of the triangle (3) on part (B).

  The triangles (12) and (13) comprise a hinge on the stop (14) as represented by the arrows (H).

  The triangles (12) and (20) comprise a hinge on the stop (33) as represented by the arrows (I).

  The triangles (13) and (25) comprise a hinge on the stop (32) as represented by the arrows (K).

  The triangles (25) and (20) comprise a hinge on the stop (26) as represented by the arrows (M).

  The image of the edges of the part (B) on the part (H) also comprise joints As the stop (31) which passes through the diamond (90) is the articulation of the triangle (2) and the triangle (3) represented by the arrows (J). The triangles (81) and (40) comprise a hinge on the edge (36) as represented by the arrows (N).

  The triangles (80) and (41) comprise a hinge on the stop (37) as represented by the arrows (0).

  The rhombus (90) consists of triangles (2) and (3) very flexible which include a bend on the edge (1).

  The small diamond (90) very flexible has a slope (P). The slope (P) of the rhombus (90) causes the stop (14) to incline the triangles (12) and (13) downwards as shown by the arrows (Q) and (R).

  This slope (P) of the rhombus (90), also inclines the stop (82) and the triangles (80) and (81) upwards as shown by the arrows (S) and (T).

  On the section (T) there are also two rings of trapezoids connected to each other at the end of the straight lines of the large bases and by the same small bass on the symmetry (I) as shown in FIG.

  Two of these trapeziums (75) and (76) of the same small base (77), such that the trapezium (75) of the part (H) and the trapezium (76) of the part (B) comprise an inclination inside the cup as shown by the arrows (U) and (V).

  The ring of trapezes such as the trapeziums (75) and (76) of the same stop (77) on the plane (P) has a space (W), to accommodate all the triangles and rhombs forming one and the same object as shown in Fig.2 where the stop (78) of the trapezium (75) is the largest side of the triangle (41) and the stop (95) of the trapezium (76) is the largest side of the triangle (25).

  The largest side of the triangle (40) is the end (89) of the trapezium (79) such that the stop (55) of the trapezium (88) is the largest side of the triangle (20).

  The largest side of the triangle (40) has a slope identical to the trapezium (75) of its same stop (89) and the trapezoidal slopes will be taken up by the longer sides of the triangles throughout the ring. trapeze on both sides.

  The trapezoid rings of the parts (H) and (B) connected to one another at the ends of the lines of the large bases and of the same small bases which comprise a hinge (X) as shown in FIG. enter the small bases towards the inside of the object and the big bases towards the outside.

  Trapeze rings composed of diamond-shaped spaces (W) all have a hinge such that the trapezium (76) and the triangle (25) have a hinge (Y) on their same edge (95).

  The trapezium (75) and the triangle (41) have a same articulation (Z) on the stop (78) and the trapezium (79) also comprise a hinge (D) with the triangle 2873353 (40) on the stops (89) where the trapezium (88) and the triangle (20) have a hinge (E) on their same edge (55).

  The set of spaces (W) on a section (T) will be occupied by the assembly of the triangles, (20), (25), (12), (13), (81), (80), (41) , (40), the rhombus (90) and all have a hinge on their edges.

  By superimposing several sections (T) as shown in FIG. 1, the large trapezoidal bases include a hinge (F) which tends to protrude from the outside of the cup.

  By superimposing a set of sections composed of a bottom, a cup is obtained as shown in FIG.

  Then when the user exerts a pressure (8) upwards and a pressure (9) towards the bottom of the cup he bends the soft diamonds (90) on the axes of the planes (P), folds the edges (77), ( 95), (55), (78), (89), (25), (33), (14), (32), (36), (82) and (37) in the direction of the arrows ( X), (F), (Y), (E), (Z), (D), (M), (I), (K), (H), (J) (O), (G), (N / A).

  So that the trapezium (75) only forms one with the (76). Such as the trapezium (79) forms only one with the (88). Where the triangle (20) and (25) form one. Where the triangle (12) and (13) form one.

  Where the triangle (81) and (80) form only one. And the triangle (2) and (3) form one.

  All these triangles fold over each other and cause certain edges to touch each other such that the stop (14) and the stop (82) forming only one, so that the stop (32) and the stop (33) touch each other. The stops (95), (55), (89) and (78) all touch when the cup is bent.

  The inclination of the trapeziums in the direction of the arrows (U) and (V) makes that in the course of the folding the large bases of the trapeziums leave towards the outside of the object and the small bases return inside the object.

  This folding technique occurs on the entire object. And this process adapts to many geometric shapes.

  The user can fold and unfold his cup as many times as he wants.

  The compound objects of the volume reduction technique increases the grip in the hands.
