Description

The The invention relates to an insulating tube sleeve containing a flexible, flat carrier and one with the carrier connected flexible, flat insulating part, whose thickness is a multiple of the thickness of the carrier.

in the Area of hot water supply it is common to container and thermally isolate pipelines. The containers are for this purpose, for example, clothed with a foam layer, which in turn is enclosed by a cover layer. Latter has mainly aesthetic tasks. The pipelines are usually made by means of half-shells made of hard foam insulated, which are adapted to the diameter of the pipe in question and enclose them completely. Here are the Connections of pipelines to containers problem areas, because on the one hand the isolation of the container for the pipe connections must be left out and on the other hand the pipe insulation mostly not in the area of Connection points usually existing fittings such as sleeves, screw caps, Stopcocks and the like fits. Therefore, the concerned Areas often inadequate or not isolated at all.

In the Austrian utility model AT000403U1 is described a closure device for openings, which are particularly in the range of pipe connections in insulating caps of containers. The closure device consists of a preferably open-celled and / or flame-retardant plastic flexible foam and a cylindrical or tubular core part which is provided in an end region with an annular flange formed thereon, wherein the flange has a multiple of the density of the core part. Although a tight closure of the container insulation in the region of a pipe connection is achieved by this closure device, but it does not solve the above-described problem of different diameters of pipes and fittings.

Therefore the invention is based on the object, a Isolierrohrmanschette to suggest that easy and inexpensive to manufacture as well as easy and quick to assemble without this assembly due to differences in diameter between pipes and fittings is hampered.

These The object is achieved according to the invention that the carrier on its side facing away from the insulating part Side wearing a side of a velcro and that the carrier on one side over the insulating part protrudes and in this projecting area on the insulating part bearing side the complementary side of the velcro wearing.

Of the achieved by these features of the invention The advantage is in particular that this Isolierrohrschelle extremely Easy to install and remove, and due to its flexibility through fittings such as fittings, shut-off devices and the like bridged conditional diameter differences. By the above range, it is possible to stick the two To connect surfaces of the Velcro in a position in which the insulating part to a closed tubular Body is rolled up.

To an embodiment carries on the carrier its side facing away from the insulating part, the fleece side of the hook and loop fastener and in the above area on the side carrying the insulating member Hook side of the Velcro. With fleece side is in this Meaning a material containing fiber loops, in which the fine hooks of the hook side hang.

To another embodiment carries the carrier on its side facing away from the insulating part, the hook side of the Velcro and in the above area on the insulating part supporting side the fleece side of the Velcro.

A further embodiment provides that the hook side the Velcro at least approximately the whole the Insulating part facing side of the carrier covered. This has the advantage of a particularly simple production of Isolierrohrmanschette.

If according to another embodiment of the insulating part A nonwoven is used in combination with the previously mentioned Implementation achieved that the insulating part through the Hook side is connected to the carrier and thus no separate measures for the connection between Carrier and insulating part must be provided. This fleece of the insulating part is preferably a polyester fiber fleece.

A further embodiment provides that the carrier contains a textile material. This is a good flexibility ensured at high tensile strength of the carrier.

The Invention will be described below with reference to the drawings Embodiments explained in more detail.

It demonstrate:

1 a side view of a first embodiment;

2 a side view of a second embodiment;

3 an embodiment in a rolled-up state and

4 an insulating pipe boot mounted on a pipe connection of a tank.

introductory It should be noted that the same in the differently described embodiments Parts with the same reference numerals or the same component designations provided throughout the description Revelations mutatis mutandis to the same parts with the same reference numerals or the same component designations transmitted can be. Also, those chosen in the description Location information, such. B. top, bottom, side, etc. on the immediate described and illustrated figure and are at a Change of position mutatis mutandis to the new situation transferred to. Next can also be individual features or combinations of features from the different ones shown and described Exemplary embodiments for themselves, inventive or inventive solutions represent.

All Details of value ranges in objective description are to be understood that these arbitrary and all subregions from this include, for. For example, the information 1 to 10 should be understood as meaning that all sub-areas, starting from the bottom Limit 1 and the upper limit 10 are included, d. H. all Subarea begin with a lower limit of 1 or greater and ends at an upper limit of 10 or less, e.g. B. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.

1 shows a first embodiment of a erfindungegemäßen Isolierrohrschelle 1 in a side view. A preferably consisting of a textile material band 2 is provided on its upper side with a fleece or fleece layer. On the lower side of the band 2 this one on the left carries a velcro backing on part of its length 3 with down-facing Velcro hook 4 , On the remaining, larger part of its length is the band 2 on its underside with an insulating fleece 5 busy. The insulating fleece consists for example of polyester fibers and is with the tape 2 for example, connected by gluing, welding or sewing,

As 2 shows, also an embodiment is possible in which the Velcro carrier 3 is omitted and instead the band 2 on its entire length with Velcro hooks 4 is provided. In the area of the insulating fleece 5 serve the Velcro hooks 4 for its attachment to the band 2 ,

3 shows how the Isolierrohrschraschette 1 to 1 or 2 is rolled up for use. The Velcro hooks engage in the fleece or fleece layer at the top of the band 2 and thus hold the insulating tube sleeve 1 closed. Thanks to the elasticity of the insulating fleece 5 this will be at the joint 6 slightly radially compressed, so that the insulating ear cuff is completely closed.

Of course, the described principle of the hook and loop fastener can also be reversed by the Velcro hooks 4 in the embodiments after 1 and 2 upwards or in the illustration after 3 facing outward and the fleece or fleece layer according to down or inside.

4 shows in a partial section an application example of the invention Isolierrohrmanschette 1 , On a container 7 is a pipe socket 9 arranged, for example, welded. The container 7 is with a tank insulation 8th provided, which in the area of the pipe socket 9 is excluded to make room for the connection of a pipeline 11 to accomplish. The latter is in this example with the pipe socket 9 by means of a pipe fitting 10 connected. The pipeline 11 is with a line isolation 12 , For example, provided from rigid plastic foam, which at a distance in front of the pipe fitting 10 ends, so that the adjacent union nut of the pipe fitting 10 can be solved if necessary. As the 4 makes clear, the connection point is through the Isolierrohrmanschette invention 1 completely enclosed. Due to the elasticity of the Isoliervlieses the different diameters and shapes, in this example due to the pipe fitting 10 , optimally balanced.

An example of a Isolierrohrmanschette invention 1 , which is suitable for connection sizes from ½ '' to 2 '', has approximately the following dimensions. The total length of the band 2 is 350 mm, its width 120 mm. The insulating fleece 5 has a length of 300 mm and a thickness of 20 to 30 mm. The Isolierrohrmanschette can of course be made in any dimension. It can also be cut to size as needed. For example, to adjust the length, the insulating tube boot becomes 1 just on the in the 1 and 2 cut off right side.

Testing The Applicant have found that by attaching inventive Isolierrohrschetten an energy savings of about 0.1 kWh / 24h per water-bearing connection is achieved. At average 5 connections of a hot water tank gives this a Savings of approx. 0.5 kWh / 24h.

For the sake of order, let me conclude indicated that for better understanding of the structure of the Isolierrohrmanschette these or their components were shown partially uneven and / or enlarged and / or reduced.
