    Collet casing. Technical area
    The present invention relates to a casing for a so-called "truss", i.e. a support structure used for temporary building structures on stages on which various light and sound equipment and the like can be hung.
    The invention further relates to the combination of a truss with a truss casing and a method for building a temporary structure for suspending various light and sound equipment above a stage, using the truss casing of the invention. RV ...
    State of the art technology
    Temporary 'structures around various lighting' and sound equipment 'on' té hängen bbvén and a stage of, for example, 'a rock festival' are simply raised by means of trusses, of which two general "types1 irreplective view are shown in figures 1 and 2 and in cross-section in figures 3 and 4. These trusses are really made from metals such as aluminum or alloys thereof with the eye on light balance, maneuverability and practicability. From this it follows that "the trusses usually have a silvery, shiny gray structure! V. Many artists or musicians hate it when these trusses are visible anyway of the structure: eiyan and. Wish they were covered. , become, for example, black "Weave," so that "the! . . visibility during the performance has been reduced. "This is, however, one" difficult and time-consuming work. "
    Explanation of the invention
    It is. an object of the present invention to provide a truss cover that can be quickly applied.
    This object is achieved according to the invention with a truss cover which has the technical characteristics of the first claim.
    The truss casing of the invention is characterized in that: it comprises a tubular piece of elastic fabric with a predetermined stretch-stretched circumference and a predetermined degree of elasticity so that it fits snugly around at least one conventional truss type.
    As used herein, non-stretched circumference is intended to mean the length of the interior of the tubular piece of cloth in the non-stretched state. . . ". "-"
    As used herein, it is not meant that the degree of gradation is the niatè in which the canvas can be subjected to an objection of disruption. or damage. This 'property' is expressed as. a "percentage equal to the achievable extra length relative to the original length, e.g. an" elasticity degree of "100% means that the fabric can be stretched to twice its original length, an e asticity rate of h 150% means that the canvas can be up to two-and-a-half times the original length. Edited, erz. "1". <; Jn. advantageous delivery methods are pre-established. prhtrek and the predetermined degree of elasticity of, the. selected such that the truss casing can be used on at least two common truss types with different circumferences. Preferably, the predetermined line-stretched circumference and the predetermined degree of elasticity of the cloth are so selected that the stress envelope can be used on trusses within a predetermined range of circumferences, meaning that the unstretched circumference below the lower limit of the range is and the degree of elasticity is chosen such that the fabric can be "omirèk" above the upper limits of the range. ""
    In a first advantageous embodiment, the properties of the truss casing are chosen such that they can be used on trusses with circumferences in the range of about 90 cm to about 120 cm. Suitable properties are, for example, a non-stretched circumference of 5 to 60 cm and a degree of elasticity of 100-160%. An example of such an embodiment is a truss casing with a non-stretched circumference of approximately 56 cm that can be stretched to 130 cm and thus has an elasticity of approximately 132%.
    In a second advantageous embodiment, the properties of. the truss casing selected so that they can be used on trusses with a circumference in the range of about 120 cm to about "160 cm." Appropriately suitable features are, for example, one and the same elongated circumference of 100% and an elasticity of 100%. 160% An example of such an embodiment is a truss casing with a "stretched-out" shape of about 76 cm which can be stretched up to 17 cm and thus has an elasticity of about 124%. Moreover, in all embodiments, the covers of the doctrine are preferably chosen in such a way that, during use, a frame for a frame for which it is intended, can be stretched a little further to clamp lighthouse sound equipment on the coated frame of the frame. It is thus possible to prevent the user from having to cut off pieces from the truss casing in order to be able to secure these or clamps. et. collet casing will be damaged by attaching these clamps. With the döék, jh "": the previous state of Van.'dé technique would use this inevitably ..
    zlJn · - -. ·. .
    ; In the preferred embodiment, the tubular piece of cloth is preferably made by knitting because it can be easily ensured that the predetermined degree of elasticity is achieved. The technique of circular knitting is used to produce the: spéhtómhulserv of the invention, whereby a so-called VyÓrdf "io.ivermedèn; Knitting and knitting are techniques which are well known in the textile industry and therefore require no further explanation here." use of these techniques also has the advantage that the tubular piece of cloth can be produced practically unlimited lengths and delivered on rolls, the user of which simply cuts off the desired length.
    The truss casing is preferably made from fire-retardant material, such as, for example, yarn composed of polystyrene fibers or containing at least these fibers. The use of this material also has the advantage that the truss cover is washable and reusable. Alternatively, other materials such as, for example, cotton could be used "with a permanent flame retarding cóëting" "also". "- fiét1 spantblmhuisél. Van 'de'uMnding.

    With the truss casing 3 of the invention, temporary structures with trusses 1, 2 can be erected as usual, but the truss casing is arranged around each truss to be coated (ie these trusses for which coating is desired, which in all cases will be all trusses) ) before it is connected to other parts of the temporary structure. For this purpose, the truss casing, which is supplied, for example, on a roll, is cut to the desired length of the respective truss; After the temporary structure has been erected, the clamps 4 for additional equipment (light, sound or other equipment) can be attached to the cladding 'trusses' without cutting away the portion of the truss cover at the place of attachment, what is possible 'as a result of' the elasticity of the truss casing. As a result, damage to the truss cover can be avoided and can be used again afterwards.
