REMOVABLE SURFACE COVERINGS Filed Aug. 21, 1964 INVENTQR AAFKO MARING BY W d gfgd ma ATTORNEYS United States Patent Ofitice 3,300,211 Patented Jan. 24, 1967 3,300,211 REMOVABLE SURFACE COVERINGS Aafko Maring, Konstanz, Germany, assignor to L. Stromeyer & Co. G.m.b.I-I., Konstanz, Germany Filed Aug. 21, 1964, Ser. No. 391,270 Claims priority, application Germany, Aug. 24, 1963, St 21,010 4 Claims. (Cl. 273-27) This invention relates to a removable surface covering consisting of one or more flexible webs which is intended-according to the size, material and quality of the samefor covering freshly prepared concrete road surfaces and mainly as a protection against drying out of more or less horizontal surfaces of buildings or as a protection against rain for covering for example cricket pitches and similar playing and sport areas.

For laying and also for removing the individual webs of such a surface covering, an elastic airtight member is provided according to this invention which is capable of being inflated to a cylindrical hollow body which can be used as a Wrapping drum.

The said member, in the inflated condition, has a cylindrical shape like a roller and according to a further fea ture of the invention may be applied to the surface covering Web at one end or near to one end of the same and may be made in one therewith to form a unitary whole. In this case the pneumatically inflatable member is advantageously made substantially of the same material or entirely of the same material as the respective web. Both may be made of plastics sheeting or for example coated and/or impregnated textile material. It is preferred to use materials and processing methods such as are conventional in inflatable tents. This is also true of the inflation valve and accessories. The web and/or the member inflatable into a wrapping drum may be provided with edging of flexible webbing or tubular material, and in the latter case the tubular material may also be inflatable, possibly with a higher pneumatic pressure than the interior of the wrapping drum. After the web has been completely rolled up onto its inflated wrapping drum, the free end of the web can be secured to the preceding winding of the same by means of buttoning means, buckles or the like. In this Way each web can be very conveniently conveyed to another place, namely by rolling it along.

The accompanying drawing shows in a purely diagrammatic way one embodiment of the invention, the drawing being limited to those features which explain the inventive idea.

FIGURE 1 is a perspective view of a single surface covering web prior to being inflated and rolled out;

FIGURE 2 is a perspective View of the same web after it has been inflated but again prior to being rolled out; and

FIGURE 3 is a perspective view of the same web as in FIGURES 1 and 2, inflated and having the free end secured, i.e. ready to be conveyed by rolling it away.

Referring to FIGURES 1, 2 and 3, a web 1 of a surface covering has at one end an end portion formed as an inflatable member 2 having an inflation valve 3. The inflated end portion, i.e. the wrapping drum 2, is a cylindrical member in the form of a roller, while when not inflated it lies flat as shown in FIGURE 1. The deflated condition is set up, if necessary by opening the valve 3 and releasing the pneumatic pressure, when the web 1 with its fully unrolled surface is to fulfill its function, for example as a protection against rain. If the web 1 is not required for a long period, it may be rolled in the condition shown in FIGURE 3, for example into a storage shed, and put away and stored, again by releasing the pneumatic internal pressure by opening the valve 3. A row of buttonholes is indicated at 4. The rearward stitching 5 of the buttons belonging to the buttonholes 4 is shown in FIGURE 2, in which the buttons themselves are obscored by the web 1, because they lie on the side of the web turned to the ground (building site). The distance between the buttons 5 and the buttonholes 4 is chosen so that after the web has been rolled onto the inflated wrapping drum the buttons lie beneath the buttonholes and can be inserted into them. The arrow A in FIGURE 2 indicates the direction in which the individual web 1 including its wrapping drum 2 must be rolled out so that the whole may fulfill its purpose, namely so that the web 1 with the full extent of its surfaceindicated by broken lines-may participate for example in the protection of a cricket pitch, in which case the pneumatic pressure must be released, as already described above.

I claim:

1. A surface covering comprising a flexible web having an elastic airtight member at one end thereof capable of being inflated to a cylindrical shape to serve as a wrapping drum when in inflated condition for rolling said web there- 2. A surface covering comprising a flexible web and an inflatable member adjacent one end of the web and integral therewith, said member being inflatable to a cylindrical shape to serve as a wrapping drum for rolling and unrolling said Web thereon.

3. A surface covering as set forth in claim 1 wherein saifl flexible web and said member are of the same materia 4. A surface covering as set forth in claim 1 wherein the free end of said web is provided with interengaging securing means for holding the web in wrapped position on said wrapping drum.
