DESCRIPTION:
In order to explain the invention, it is necessary to describe the basic module with which grouping in an ordered manner as indicated below, allows the construction of a folding system of articulated dome-type straight bars.
2 PATENT: SYSTEM OF DEPLOYABLE STRUCTURES WITH STRAIGHT BARS FOR DOMES
The module or minimum unit is a hexagonal geometry form /. Made up of six pairs of asymmetric simple scissors 2 on the surface of the hexagon. And six more pairs of simple scissors 3 grouped radially and concentric to the base hexagon. The simple scissors are formed by two straight bars with equal dimension. And they are articulated in an asymmetric center 4 to allow simple curvature in the plane.
If the articulation is in the center of each bar, the movement will be linear and not curved, making it impossible to generate synclastic surfaces. The asymmetry of the center for the straight bars will depend on the calculation made for each case. If the single scissors unit is more widespread when the dome or system is fully deployed or open, it will need a short asymmetry. If you want a unit of simple scissors less extended when the dome or system is fully deployed or open, you will need a long asymmetry.
In each joint node between the ends of the straight bars there will be a hexagonal connection that will allow the movement or pivot of each bar, making possible the fluid movement of the module. Unfolding or open when the hexagonal module is occupying more space. And folded or closed when the module is occupying the least space. The foldable or collapsible dome of the present invention is formed by the grouping of the hexagonal modules described above.
The selected geometry is the icosahedron. Its transformation or partial displacement results in a truncated icosahedron. From the truncated icosahedron we take a section 6 less than half cut by a plane intercepting five pentagons at its base. The geodesic section of the resulting truncated icosahedron is made up of six pentagons 7 and five hexagons 8. From a central pentagon five hexagons are grouped by their edges. The hexagons are joined together by the edges of the contiguous hexagon. And the five missing pentagons 9 join the concave edges between the hexagons radially. To complete the dome we join five half hexagons that connect to the perimeter pentagons. All the edges formed by the section of the truncated icosahedron are dimensionally equal.
The last step in the geometric construction of the deployable dome which is the object of the present invention, is to replace all the hexagonal polygons with hexagonal unfolding modules of articulated straight bars 2. And the half hexagonal polygons are replaced by half hexagonal modules with pairs of articulated scissors 2, thus completing the geodesic section. The circular perimeter of the base is completed by joining the half hexagons with a simple scissor 3 closing the pentagonal holes.
In summary, the collapsible or foldable dome consists of five hexagonal modules 8 or deployable units with five half hexagonal modules or deployable units. And six pentagonal spaces Z.
The core geometry is the one described above. It is possible to change the size of the system without changing the dimensions of the bars. This is possible if the frequency of the geometry or section in the truncated icosahedron is increased. As a consequence we will have a larger system with the same dimension of bars but more number of them.
The process of folding and unfolding are defined in three phases or stages Fig.3. The first stage is when the system is at its maximum opening or deployed point. This stage is the

This is possible if the frequency of the geometry or section in the truncated icosahedron is increased.

The process of folding and unfolding are defined in three phases or stages Fig.3. The first stage is when the system is at its maximum opening or deployed point. This stage is the

usage stage, forming inside a habitable shell. The geometry is shaped by five hexagonal modules or deployable units and five hexagonal media modules or deployable units. And six pentagonal spaces. The second phase or stage is the movement point or collapsing. To generate the collapse or closure of the system, the structure needs a small force or "whip-like blow" from the internal knots of the central pentagonal opening. The force applied is vertical to the support plane of the system. And from outside to inside the system. The system of articulated straight bars 2 and pivots or hexagonal knots 5 allow fluid movement of the system from the outside to the inside. The third and final stage is the maximum folding or closing of the system. This position is when the bars are totally closed occupying the smallest possible space. This stage is when the invention is portable.
The simple scissor unit 2 is formed by two pairs of straight bars articulated asymmetrically.
This joint is made with a simple pin that allows the rotation of the bars. The hexagonal piece or node is the one that allows the union of the simple scissors units that form the hexagonal base module. The union or node of six pivot points is displaced from its central axis keeping one of its faces on the axis. The piece has a hole 10 in the middle perpendicular to the central face. This hole is what allows the anchoring of the flexible or rigid enclosure of the system. As well as the fastening of the safety pin that maintains the structure without risk of collapse. This piece or hexagonal node is used in all connections between simple articulated scissors of the system. Except in the circular outer perimeter of the system.
The hexagonal part or node of four pivot points Fiq.5 is displaced from its central axis keeping one of its faces on the axis. The piece has a hole 11 in the middle perpendicular to the central face. This hole is what allows the anchoring of the flexible or rigid enclosure of the system. As well as the fastening of the safety pin that maintains the structure without risk of collapse. This piece or four pivot hexagonal node is used for the connections of pairs of scissors at the outer perimeter of the system.
The compatibility conditions of the system Fiq.6. The first condition of compatibility is the position and direction of the articulated straight bars. The simple scissors are formed by two straight bars with an asymmetric central joint. The shortest distance from the center to one of its ends will always be in the inner part of the system. And the longest distance from the center to the other side of its ends of the bar will always be towards the outside of the system.
The second compatibility condition is the union of the hexagonal node with the straight bars.
The correct position for the connection of one of the pivots of the node with the end of the bar is perpendicular to the ninety degree right angle of the hexagonal part or node. The bar can rotate with fluid movement with this connection. And the system will have a fluid movement. The third condition of compatibility is the position of the simple scissors wrch respect to the union of the hexagonal node. Each pivot point of the hexagonal piece must be between the two articulated bars of the simple scissors. If these three conditions of compatibility are not met, the system will be blocked from movement or will not be fluid.
The collapsible system or dome related to this invention includes tuning parts and anchoring elements to use in conjunction with the articulated bars and the flexible or rigid shell 14 for the whole system. Each joint between the articulated straight bars and the pivot of the hexagonal part is made by a pin 12 that allows the rotation of the bars. This pin will have at one end a blocking system that prevents its exit. As for example a self-blocking nut. The

The correct position for the connection of one of the pivots of the node with the end of the bar is perpendicular to the ninety degree right angle of the hexagonal part or node. The bar can rotate with fluid movement with this connection. And the system will have a fluid movement.

Each joint between the articulated straight bars and the pivot of the hexagonal part is made by a pin 12 that allows the rotation of the bars.

5 by a pin 13 which is going through a hole 10. Also, the pin allows to make the flexible or rigid shell 14 in the internal face of the system. Elements such as lighting or decoration can be supported using these points to hang it within the system. The maximum weight of the elements to be hung will depend on the calculation made of the system and the maximum limit of rupture allowed by the material and its section. The pin 13 that holds the enclosure will have a variable height according to the material selected to prevent the clash between the articulated bars and enclosure material.
The system is self-supporting and can stand without external elements. This condition is when the dome is in the use or maximum deployment stage. To guarantee the non-sudden collapse or closure of the system caused by some external factor, a safety pin 15 is required between the two hexagonal parallel pieces of the hexagonal modules. At least one in each hexagonal module center is required. This safety pin 15 will prevent the sudden collapse of the system.
The enclosure of the deployable dome or system can be flexible or rigid Fig.9.
The flexible system requires a sewing pattern of triangles shaped and joined by five hexagons and five half hexagons. It is formed by five pentagons as well which can be used as access doors to the interior of the deployable dome. These shapes can be attached to the hexagons and half hexagons or they can be independently. This sewing pattern allows the best movement of the enclosure within the system in its maximum folding. In the stage of use or maximum deployment, the flexible enclosure gives greater stability to the system or deployable dome.
The flexible or rigid shell can be located whether outside or inside of the dome frame. Also it can be on both internal and external sides to create a void in between that could produce a great weather isolation.
A Deployable Dome can be used in the greenhouse industry as a solution for small farms and users with the purpose to setup a quick farm production system.
