A damage-free mountable and removable arresting device for a foil or a similar thin covering material for making temporary or permanent coverings, encasings, spacial partitions and the like, comprising a plurality of self-supporting longitudinal clamping bars, each formed with at least one groove extending in a direction of a longitudinal axis thereof. An elastic band is pressed into the grooves of the clamping bars and one or more connection clamping elements are inserted into the ends of the grooves for operatively connecting the plurality of clamping bars.

The subject invention relates to a damage free mountable or removable arresting for a foil or a similar thin covering material for making temporary or permanent coverings, encasings, space partitions and the like, essentially consisting of a self-supporting clamping bar with one or a plurality of grooves formed at its surface, a band impressed into the grooves made of an elastic material, and one or a plurality of insertible clamping connection elements which are inserted into the ends of the grooves of the clamping bar for providing a linear or angular fixed, rigid or flexible connection between a plurality of clamping bars, or for stiffening and/or spacially fixing the entire system.
For the production of provisional or permanent coverings, encasings, space partitions and the like, it is known to use covering materials made, for example, of paper, foils or cloth, which are mounted onto frames or simple framework structures and with longitudinal and lateral connections made of frames or boards which are arrested in desired position by nails or screws. This, however, requires a lot of material and is rather time consuming for making fixedly mountable coverings, encasings, spacial partitions, etc. This may still be acceptable despite the fact that a lot of material is needed and a lot of time is required. However, this way of making the covering is completely unacceptable for such structures which are very often required for provisional coverings, encasings or spacial partitions, etc., which are mounted at one place and may be dismantled to be erected at another place. It has been shown that the base material for making these structures as well as the frame or framework structures cannot be used for a different structure or cannot be used at a different place, so that new base material has to be employed. This does not mean that an increased amount of time has to be spent for cutting the new frame or framework parts as well as the new covering material, so that the desired size is obtained, but it also increases the cost of manufacturing. The increased costs are specifically noticeable when provisional structures are made which have to be mounted at different places, dismantled and again mounted at another location.
The prior known covering systems are also disadvantageous in that the construction is relatively complicated, so that it has to be made by experts, requiring a lot of time and material expense. Since the covering material cannot be used again after once being mounted at one place and then being dismantled (e.g., a temporary encasing or material) so as to be placed on another site, however, because the thereby damaged material must be disposed of, there also occurs the problems of waste removal apart from the cost of the materials.
In the drawings, wherein similar reference characters denote similar elements throughout the several views:
FIG. 1 is a perspective view of a damage-free mountable and removable arresting system for a foil or a similar thin covering material in an "overlap connection" in accordance with the invention;
FIGS. 2a to 2e are perspective views of various embodiments of the clamping bar of the invention, partly broken away;
Referring now to FIG. 1, there is shown one embodiment of the invention of a damage-free mountable and removable arrest for a foil or a similar thin covering material comprising two clamping bars 1 and 1' having a square cross section (of edge lengths A). A longitudinal groove 2 with dove tail cross section, is always formed in the center of each of the four edges, and a rounded deformable band 3 which is wrapped with a foil 4 is pressed into the groove. The two clamping bars 1 and 1' form a rectangular connection and are fixedly connected with each other by means of a connection clamping element, whereby only one inserted end 5 is shown in cross section.
FIGS. 2a to 2e show a preferred embodiment of the clamping bar of the invention having a square cross section which is solid; having four centrally located grooves 2 with a T-shaped cross section (FIG. 2a) which is solid within; and with four centrally provided grooves 2 with U-shaped cross sections (FIG. 2b); and the grooves having a dove-tailed cross section in the oblique side walls which are formed with an additional recess 2' (FIG. 2c). The clamping bar 1 is provided with an opening 6 passing therethrough in the axial direction with open ends, as well as centrally provided grooves 2 having rectangular or square cross sections of which the side walls of the grooves 2 are provided with layers 2" which are made of an elastic material becoming thicker toward the upper surface of the clamping bar 1 (FIG. 2d), or with axially extending hollow spaces 6 and 6', having open ends, as well as four centrally arranged grooves 2 with dove-tailed cross sections (see FIG. 2e).
FIG. 3 shows the self-supporting clamping device 1 of the invention having a rectangular cross section with the edge lengths A and B, and grooves 2 with dove-tail like cross sections, whereby the device can be covered on both sides with a foil in such a way that the foil upper faces have the distance B and/or A from each other.
