FR2567176A1 - STRUCTURE CONSISTING OF ARTICULATED ELEMENTS FORMING A TYPICAL PANTOGRAPH SYSTEM, IN PARTICULAR TO SUPPORT A COVER. - Google Patents

Abstract

THE INVENTION RELATES TO A STRUCTURE1 FORMED BY A SUITABLE NUMBER OF ELEMENTS2 WHICH, ARTICULATED WITH RESPECT TO OTHERS BY MEANS OF ANCHORS3, FORM AN ARTICULATED SYSTEM OF THE PANTOGRAPH TYPE. THE ELEMENTS2 ARE ARTICULATED AT THE POINTS WHERE THEY CROSS AND AT THE ENDS. THEY HAVE A PERMANENT CURVATURE OR SUFFICIENT FLEXIBILITY TO ENSURE A CERTAIN BURN ON THE WHOLE AFTER ASSEMBLY. THE DIMENSION OF THE STRUCTURE DEPENDS ON THE LENGTH AND THE NUMBER OF ELEMENTS USED. MOUNTING IS DONE BY EXTENSION OF THE ARTICULATED SYSTEM UP TO A LIMIT ESTABLISHED IN ADVANCE. ON DISASSEMBLY, THE SYSTEM FOLDES UP AND TAKES A SMALL SPACE. THIS NEW STRUCTURE HAS ALL KINDS OF APPLICATIONS AND CAN BE USED IN PARTICULAR TO SUPPORT ANY TYPE OF COVER.

Description

The present invention relates to a structure formed by elements

  articulated with each other

  forming a pantograph type system.

  Structures of this kind have already been disclosed, some constituted by fixed elements, the others by articulated elements. However, a structure with articulated elements whose characteristics are those of the invention has not yet

been presented.

  Indeed, this new structure has characteristics such as assembly and disassembly by extension or extension of the articulated system, the possibility of curvature of the structure whenever it is mounted, the lightness, the stability of the whole at the course of its use and the versatility of its applications and characteristics distinguishing it from other structures

  known composed of articulated elements.

  This new structure is essentially constituted by a suitable number of elements which, articulated with respect to each other, by means of axes or dowels for example, form an articulated system type pantographo The elements that form the system are articulated one by one in relation to the points where they

cross and at the ends.

  The extremities of the external elements are the only ones which are free, that is to say, which are not articulated. The entire articulated system operates, therefore, in the same way as

of a pantograph type system.

  Thus, any action exerted on external elements is immediately transmitted to the whole system. This allows extremely fast assembly and disassembly of the structure that requires only one operator, which however does not need to exert any violent effort when it comes to structures

of appropriate dimensions.

  The aforementioned elements that make up the structure

  may be slightly curved or have sufficient flexibility

  health so that they bend themselves to the assembly. In these conditions we

  can obtain a structure in the form of an arc.

  For this purpose it will suffice to mount the structure while exercising

  making an adequate effort on one side of it while

  keeps the opposite end fixed.

  The structure is maintained in a service position, complete

  mounted and curved, by fixing the ends of the outer elements. For this purpose, it will be sufficient to ensure that the ends are immobile with respect to each other and, for this, it will be sufficient to maintain them attached appropriately, by

example, by means of tensioners.

  The size of the structure depends on the length of the

  its constituent elements and the number of elements used.

  In case the elements are sufficiently curved at the beginning and / or are sufficiently flexible, it is possible to obtain a

  structure which, when it is mounted, can

  vation, a semicircular configuration, which does not require

  in addition to those described in the above for the structure of

  itself, however, in general, the curvature and / or flexibility will be just sufficient to impart a camber to the structure.

  corresponding to an arc less than a semicircle.

  For a better understanding of the present invention will be found in the appendix a sheet of drawings, which have no limiting catactère, o is presented a model embodiment in which the elements themselves are curved at the start, in the state relaxed, and o: Figure 1 shows a view from above; Figure 2 shows a front elevational view; and

  Figure 3 shows a perspective view.

  As can be seen in the execution model represented

  the structure, designated generally by 1, is constituted by a suitable number of elements 2 which articulate with each other forming an articulated system of the pantograph type,

  as is evident from Figure 3.

  The aforesaid elements 2 are articulated with respect to each other at the points where they intersect 3 and at the ends 4 using a method considered suitable, particularly by means of

pegs or pins.

  As can be seen in any figure of the annexed drawing, each of the elements 2 has a curvature or the shape of an arc. Thus, when the system is elongated it has a curvature or camber more or less pronounced depending on the initial curvature or the flexibility of the material - depending on the material

  constitutive elements and dimensions - elements that make up the structure

  ture. Of course, the extent of the curve formed also depends on the

  number of elements used and the degree of extension of the system.

  The curvature may even extend over a semicircle, but in most cases it only forms smaller arcs. It is possible to make sure that the system is

  expandable to prefixed limits.

  When we disassemble the structure all the articulated system

  folds and occupies only a very small place.

  The invention is not limited to the embodiment described and represents and many modifications are possible

without leaving his frame.
