Definitions

  • the invention relates to a mechanism that addresses the housing needs related to architecture, military, and civil society organizations, which can be used as emergency structures after disasters, exhibition stands, industrial tents, or roof shells.
  • This invention pertains to a cage system based on the Altmann mechanism, capable of transitioning from a closed cylindrical shape to a vault, then to a planar shape, and finally to a collapsible form.
  • the Altmann mechanism consists of structures formed by combining links with revolute joints. This mechanism has been utilized in the present invention's specification to obtain reconfigurable deployable frame structure system.
  • patent document number 2016/19595 describes a foldable frame structure.
  • the patent with number 2016/19595 has a double-layer network pattern, while the invention described in the specification forms a single-layer network structure.
  • the combination details of the networks and the way basic modules come together are also significantly different.
  • Patent 2016/19595 can remain in a single form (vault).
  • the new invention is a shape-changing frame system, allowing for multiple configurations.
  • flat, spherical, and cylindrical geometries are used to achieve the mechanism, whereas they are not required in the current invention.
  • patent document number 2014/10892 describes a reconfigurable deployable structure system. It consists of planar bar mechanisms called four-bar linkage.
  • the Altmann mechanism is used.
  • scissor systems used to assemble spatial Altmann basic modules result in a new network with improved static and movement angles.
  • the invention described in the specification can be modularly derived to cover areas of desired dimensions.
  • patent document number US10871007B1 describes a foldable frame structure.
  • the mentioned frame structure cannot take on a vaulted form and does not utilize the Altmann mechanism.
  • patent document number CN108916512A presents a structure for tent canopies. Although the structure combines links with revolute joints, it does not demonstrate a vaulted structure incorporating the Altmann mechanism.
  • the invention is a reconfigurable deployable frame system that surpasses the known prior art, addresses its disadvantages, and additionally includes extra advantages.
  • the purpose of the invention is to present a reconfigurable deployable frame system obtained by derived Altmann mechanism modules in the X and Y directions.
  • the frame system subject to the invention allows for easy portability and modular derivation, enabling design flexibility to achieve different configurations from a fully closed cylindrical form (Figure 7B) to various other forms (Figure 7A, vaulted form, Figure 8A parallel form) and adapting to desired dimensions. Additionally, due to its overconstrained mechanism, it exhibits greater resistance against static loads. The reason for having an overconstrained mechanism is the utilization of the Altmann mechanism, which consists of six revolute joints and is an overconstrained, single-loop bar mechanism.

  • the frame system subject to the invention utilizes square-sectioned links (10).
  • the links (10) used in the invention are shown in Figure 1.
  • the derivation of the structure obtained with the links (10) in the X direction is achieved using an L-shaped connecting element (11 ) and revolute joints (15).
  • the L-shaped connecting element (11 ) is shown in Figure 2A and Figure 2B.
  • the L-shaped connecting element (11 ) has connection element holes (14) on its two edges, allowing for the attachment of revolute joints (15) and the flexible connection of the links (10) and L-shaped connecting elements (11 ).
  • FIG 3 illustrates the main module of the invention, which is the scissor mechanism (60).
  • the mentioned scissor mechanism (60) is obtained by connecting the links (10) of two scissor structures (20) at their close ends with two L-shaped connecting elements (11 ) through revolute joints (15) with a 90° angle between their axes.
  • One scissor structure (20) is formed by connecting two links (10) through intermediate joint holes (13) located at their center points using revolute joints (15). Consequently, the main module of the invention, the scissor mechanism (60), is achieved by combining four links (10), two L-shaped connecting elements (11 ), and six revolute joints (15).
  • FIG. 4 illustrates the multiple scissor mechanism (50) obtained by combining two scissor mechanisms (60) in the X direction through L-shaped connecting elements (11 ) and revolute joints (15).
  • the multiple scissor mechanism (50) is formed by combining and derivating two scissor mechanisms (60) in the X direction, resulting in three large Altmann modules (30). The reason for this is that during the combination of two scissor mechanisms (60), adjacent links (10) are shared between them.
  • the multiple scissor mechanism (50) shown in Figure 4 is obtained by joining two scissor mechanisms (60) in the X direction, it can also be achieved by adding more than two scissor mechanisms (60) side by side, depending on the size of the area where the frame system will be used.
  • Figure 5 shows the structure obtained by derivating the multiple scissor mechanism (50) in the Y direction.
  • two multiple scissor mechanisms (50) are placed vertically and derivated. The number of derivations can be increased.
  • three multiple scissor mechanisms (50) are added vertically.
  • the replication of multiple scissor mechanisms (50) in the Y direction is achieved by connecting their links (10) through intermediate joint holes (13) with revolute joints (15).
  • the structure obtained by derivating two multiple scissor mechanisms (50) in the Y direction, as shown in Figure 5, consists of six large Altmann modules (30) and three small Altmann modules (40).
  • the multiple scissor mechanism (50) includes only the large Altmann modules (30), but when derivated in the Y direction with the design that utilizes shared adjacent links, it results in small Altmann modules (40).
  • the structure obtained by derivating three multiple scissor mechanisms (50) in the Y direction, as shown in Figure 6, comprises nine large Altmann modules (30) and six small Altmann modules (40).
  • the terms "small Altmann module” (40) and "large Altmann module” (30) encompass all structures that consist of four links (10), six revolute joints (15), and two L-shaped connecting elements (11 ), differentiated only by their size.
  • the scissor mechanism (60) when the scissor mechanism (60) is derivated in the X direction, it forms large Altmann modules (30), and when derivated in the Y direction, it forms small Altmann modules (40).
  • the small Altmann modules (40) limit the movement in conjunction with the large Altmann modules (30), providing a static appearance.
  • the reconfigurable deployable frame system described in the invention can transition from a closed cylindrical form (Figure 7B) to a vaulted form (V) as shown in Figure 7A, and it can maintain stability in these forms, including the planar form (P) transition from the vaulted form (V).

Abstract

L'invention concerne un système de cadre déployable reconfigurable basé sur le mécanisme d'Altmann, apte à passer d'une forme cylindrique fermée à une forme de voûte (V), puis à une forme plane (P), et enfin à une forme pliable.
