| CLAIMS CONCAVE SUPPORTS FOR HUMAN BEINGS 1 . Elements or supports (P) for seating, characterized, as indicated in the section of the Fig.( l ) of the Table (1/1 ) of the drawings, otherwise from the background art, for having a concave internal angle (Y) in the people's pelvis contact or supporting area (D). to have two parts or half-planes of constant or variable thickness (R), (S), reciprocally inclined, rigid, non-deformable and both able to bear the human weight by themselves. These two half-planes are placed between the surface concave area of the support (P) and people's pelvis (D), which at their contact point, the centre (E) of the support (P), create, in their superficial side, a convex angle (X) with a range varying from (0°+l o) to ( 180°-1 °). This convex angle (X) added to the underlying concave angle (Y), with a range varying from ( 180°+1 °) to (360°-l°) of the supports (P), create a perigon (360°), in order to form, according the entity of the convex angle (X), a triangle limited by the points (A). (B). (E), with a base coinciding with the distance between the two ischia (A), (B) and with vertex in (E). (E) is given by the joint between the two inclined parts or half-planes (R). (S) which in turn create the convex angle (X) too. Thus, being constant for human beings" anatomical characteristics, the measure of the base (A). (B) of the triangle (A). (B). (E), varying the angle (X), both the height of the base (A), (B) and the distance between (E) and (G) vary, as measure of the straight line segment given by the extension of the height of the triangle with base (A), (B). Thus, as in a mathematics function, it is possible to plan the measure of the distance from the centre (E) or from the bearing supports to the genitals (G), and consequently it is possible to obtain the measure of the convex angle (X) to create and incline the parts or half-planes (R). (S), avoiding suffering to users' genitals usually caused by traditional supports or stands (P). 2. The convex angle (X) of the parts or half-planes (R), (S), as claimed in claim ( 1 ). is measured at the joint points between the two ischia (A) and (B) and the semi-planes (R). (S). even when the same (R) and (S) are separated in the centre (E) of the supporting elements (P). 3. The parts of the elements or supports (P), under the inclined parts or half-planes (R) and (S) can have any shape or measure, both transversally and longitudinally, as creating a single element and mingling with parts (R) and (S). 4. The two parts or half-planes (R), (S) can be joined or detached in the centres (E) of the supports (P). In addition they can be superficially covered by soft amortizing materials, and can be varied at will, through an additional mechanic device, in order to modify the convex angle (X). |
CONCAVE SUPPORTS FOR HUMAN BEINGS
TECHNICAL FIELD. People usually stand, sit or lie in supine or prone positions. This invention is focused on the seated position. When in "seated" position, the users' pelvis is in contact with other elements and supporting stands which usually constrict, especially in certain positions, the lower part of the pelvis, creating suffering.
BACKGROUND ART. The cross section of the real supporting elements (P) on which people sit. have several shapes but are substantially flat or with geometrical shapes with a central flat part and with wings or external parts in order to retain laterally the pelvis (D), or are not linear in order to follow the anatomic curved line of the pelvis, wrapping it with a sort of "U" shape with the external wings directed upright - or with the external wings directed downright with a sort of "Π" shape (e.g., horse-riding saddles). A section of a traditional ' * U"-shaped support of seat does not have any half-line nor half-planes which meet at the centre of the seat to measure the angles of plane where pelvis lays. According to geometrical and mathematics principles, an angle is composed of two half-lines or two half-planes with a common vertex. No supporting or bearing element apart from this invention, is based on ang!t measures creating triangles with the two ischia (A) and (B) and the upportin,. centre (E).
DISCLOSURE OF THE INVENTION. The supports of the invention (P). as given in Fig.( l of Table ( 1 /1 ) of the drawings, are characterized by the mathematics concepts of the triangle. shaped by and hav ing as base the distance between the two ischia (A) and (B) of the pelvis ( D) and as vertex the point (E) or centre of the supports (P). The distance between the point (G) and (E) is the extension of the perpendicular segment or height of the base (A), (B) from the vertex (E) of the triangle given by the points (A), (B), (E). Varying the angle (X), the internal angles, the sides measures, the height of the base (A), (B) of the triangle (A), (B). (E) and therefore the distance (G) - (E) vary. It is possible to space out (G) and (E) because the distance or base of the triangle (A). (B) is an almost invariable measure, with slight variations between men and women. For the wellness of people, the range of the concave angle (Y) goes from ( 180°+1 °) to (360°-l °) and the range of the convex angle (X) goes from (0°+P) to ( 1 80°- 1 °). In practice, the concave angles (Y) and the convex ones (X) of the invention are measured in order to create a triangle (A), (B). (E). For the wellness of users, the supports of the invention, e.g. the seat, are characterized by and include that the two ischia (A) and (B) can lay or can be supported by elements or supports (P) with a concave shape (Y). In addition, the invention is characterized by and includes that, as illustrated in Fig. l of the Table ( 1/1 ) of the drawings, on the concave angle and hence on the elements (P), two parts or structural semi- planes (R) and (S), load-bearing, rigid, non-deformable, are put; they are able to bear the human weight by themselves and in their union point at the centre (E) of the support (P) create convex angles (X). With this shape and according to this geometrical and mathematics concept, varying the angle (X), in compliance with the necessities, the perineum area, limited by the two ischia (A) and (B) and the genitals (G), is spaced out from the centre (E) of the supports (P) and (R), (S). The semi-planes or bearing elements (R) and (S) are rigid and non- deformable, able to bear the human weight by themselves, and can be joined or detached on the centres (E) of the supports (P), in order to create a single element joining with (P). and in uuuitiLm they can be superficially cuvereu by Si-fi material, having any shape or e tern?.! ornamental pattern.
BRIEF DESCRIPTION OF DRAWINGS. Fig. 1 of the Table (1/1) of the drawings shows a cross section of the supports of the invention, characterized by a convex-shaped structural bearing element (P) in contact with the users' body following a precise angle (Y). The vertex of the concave angle (Y) coincides with the centre (E) of the supports (P). On the half-lines creating the concave angle (Y) there are two half-planes (R) and (S), rigid, weight-bearing. with a certain thickness and able to bear the human weight by themselves. The half-planes (R) and (S) are reciprocally inclined and in their centre, the meeting point (E) of the supports (P) they create a convex angle (X). The half-planes (R) and (S) support the two ischia (A) and (B) of the pelvis (D) and can be upholstered with soft material.
THE BEST MODE FOR CARRYING OUT THE INVENTION. In order to avoid the complete replacement of machinery and equipment dedicated to working and producing the current supports (P), it would be easier for the production industrial system to add inclined supporting elements (R) and (S) on the supporting structures of the current supports (P).
INDUSTRIAL APPLICABILITY. The new kind of supports proposed by the invention, including seats, chairs, armchairs and any other kind of support can be easily mass-produced and built with any kind of material, with any desired shape and measure as required by customers.
