Abstract

The electrically regulated heating mat system for open areas comprises one or more interconnected heating mats which can be embodied in any dimension and which consist of weather- and salt-resistant rubber or plastic. The heating mats are laid on the areas and, by means of fixing devices (9, 10, 18, 19, 28), are temporarily fixed to the substrate. The heating mats are operated by the supply of an electric current which is, however, supplied to the heating conductors (23) only when the situation requires. A storage film (1d) and/or a storage fabric, preferably made of aluminum, is inlaid between the parallel connected heating conductor (23) and the covering mat (1a), in order to obtain protection for the conductor and better heat distribution. The current fed into the heating mats comes from the accumulator unit (4) which is supplied via solar panels (6) and/or a mains voltage (13) of, e.g., 220V (country-specific mains voltage). The mats are flattened off towards the edges and produced with yellow and black edge markings. An optional inscription on the mats can increase safety and/or be used as advertising space.

Description

Electrically controlled heating mat system for open spaces

Electrically controlled Heizmattensystem for open spaces comprising one or more heating mats (1, 2), which can be preferably carried out in any dimension, preferably made of sandwich-weathered and salt-resistant rubber or plastic, placed on the surfaces to be protected and by means of special (preferably galvanized ) Fastening devices (9) are fastened, characterized in that the Heizmattensystem by introducing a via a wet and temperature sensor (7) and a Luftfeuchtefuhler (8) temperature, humidity and wet-controlled electrical current in the preferably made of galvanized copper conductors PTC [22 ) and subsequently to the thermistor (23), with the / between the on the lower base mat (I c) located hot lines (23) and the upper deck mat (I a) arranged flexible storage film (I d) or a flexible storage fabric (I d) of preferably aluminum aufg is created or connected so that the generated heat to the storage sheet (1 d) or to the storage fabric (1 d) to give better heat conduction and heat storage within the heating mat (I) to ensure, and then from a power supply (13) or Accumulator (4) preferably combined with a solar unit (5,6,8) are fed, the individual heating mats are connected by connectors (3) over a large area

The invention relates to a temperature, humidity and wet-controlled electric Heizmattensystem, the mnenbefindlichen heating elements are fed by electric current (from a battery preferably with solar power and / or a power supply) via a Regelemheit and thereby keep the open spaces ice and snow Without losing the slip resistance, wherein an improved thermal conductivity between the thermistors and the surface of the heating mat is ensured by the storage film or the storage fabric, with a reduced energy consumption is necessary to keep the heating mat at operating temperature and in addition the hot and cold conductors through the better protect the resulting protective layer from damage and thus simpler parallel connections are possible

From DE 200 18 040 U 1, a weatherproof floor mat with electrical heating is known, wherein the mats are connected to each other with formschlussigen electrical and / or mechanical elements (tongue and groove Verbindungseinπchtungen or wedge or Keder rods) These can also by steel bands together connected to the bottom in order to bring stability into the invention For the supply of electrical energy is connected to a mains connection power cable via a compatible connection means, which is mainly frontally used, used for the staircase, the heating elements are horizontal and vertical on the stairs placed and connected by means of sealing lips

The disadvantage is that the well-known weatherproof floor mat with electrical heating does not provide any attachment devices that connect the mats with the ground and thus only by gravity and the connection to each other remain in the desired position For a permanent Fußgangerverkehr, such as z B at the hotel entrance, Fußgangerzonen or crossing areas is common, the position of the mats composite can not be guaranteed with certainty By formschlussige connection such as the dovetail connection or the electrical

Feed through the compatible connections on the mat edge, no flattened cross-sections can be made on the edges of the mats to avoid the risk of tripping

There are no visual marks on the mat edges attached to the passers on the

To indicate mat system and thus to be careful when crossing the edge

When multiple elements are used, they are connected by steel straps

Steel bands corrode if they are damaged by the salt passages of the passers-by or the snow service on the

Nachbarsteig or come through wet salt of the road service in contact

In the staircase insert, the heating mats are also only secured by their own stability against slipping and not secured to the ground. In addition, the attachment of vertically guided

Heating mats to an unnecessary energy consumption, because on the front of the stairs no snow sticks and no one on it occurs In a large mat composite, the mats at both ends of the composite with

Energy supplied, resulting in very long loose cable connections This type of external surface heating is not suitable for permanent safe passenger transport There is no metallic fabric or foil provided to protect the wiring or the wiring from damage

From US 6,180,929 Bl a weatherproof floor mat with electric heating is known, the mats are powered by electricity from the socket (1 10, 220V) The mats are fed to the front pages via a cable clip, which is protected by a cover The mats are cut to the required dimensions Due to their geometric shape at the bottom they are secured against slipping If it is necessary, still stakes (spikes) can be driven through the mats in the underground The invention is also intended for use on roofs

The disadvantage is that the system is tied exclusively to the power supply by sockets If there is no outlet on open spaces, then a cable extension to the next outlet must be accepted The use of the invention is therefore limited to those areas in the private sector and in the vicinity of the own power supply, since public electricity, for personal use, must not be used in open spaces, where no power from the socket can be used (due to the great distance to their own circuit), this system also can not be applied A mats composite can not be synonymous Since there is no connection between two or more mats, that is, one needs a power connection per mat to a socket. At the feed points at the beginning or the end of the mat, relatively high covers are provided to protect the connections from the wet, but a trip - and risk of injury The heating on and off times depend only on the ambient temperature, this has the major disadvantage that on cold days without precipitation or too low humidity, although there is no need, the mat is still powered and thus unnecessarily much power consumed Slipping hazard or need for a heating power exists only when the temperature is at or below the freezing point of water, the humidity is high (fog) or precipitation prevails The mats are protected only by their geometric shape on the ground against slipping Is this Haftbrucke by loose ground not possible, can be fixed with thorns, which are driven by the mats, the mat. However, if the substrate is made of natural, artificial stone or bitumen, no stable and secure attachment is possible because in the ground no thread or similar counter - or

Replacement Blade (RULE 26 * Anchoring piece is therefore provided. This lack of attachment possibility is therefore not suitable for permanent passenger traffic. No metallic fabric or foil is provided to protect the wiring or the cabling from damage

The invention is therefore the object of a free-form heating of the input type to be designed so that a secure passenger transport is guaranteed by the attachment to the ground, the free pools with the lowest possible power consumption and only if a need for elimination of ice and / or Snow board is free to hold, no matter which material is the background, with a uniform temperature distribution on the surface of the mat by the positioning of a storage fabric or a storage film should also be to protect the lines

The task is solved by aligning the mat composite on the (swept) surface to be protected so that the legally required snow cover surfaces can also be heated. The mats will now be fastened to the substrate using the fastening options adapted to the substrate and the eyelets incorporated in the mats Only by this fixation can the slipping of the mats be ensured The mats are made of (preferably two sandwich processed and vulcanized or glued together) rubber mats which can be made in any dimension in meter goods, between which the hot and cold conductor elements (preferably made of galvanized copper cables or fabricated metal strips and preferably in parallel) and the overlying preferably consisting of aluminum storage film or storage fabric located at the mats ports are, if they are not be needed with a wet and sure-footed plug-in connection but these needed for more mats connections, this connector serves as a wet and sure-footed connection between the individual mats The compounds are preferably performed under the mats to mask them in mat composite and against Wandalismus to protect

In contrast to the mat material, the storage fabric can store the heat better and therefore for longer, which results in a further distance between the thermistors and / or lower power consumption. By laying the storage fabric over the parallel connection, additional protection of the hot and cold conductors from damage is achieved. whereby the possibility for a parallel connection with only one thermistor results

The power supply to the mats can be done by a mains connection (preferably 220V-230V) and a battery unit If the heating cables located in the mats are not operated by mains voltage, the mains voltage is reduced by a transformer located in the control unit to the operating voltage of preferably 48V, 24V or 12V reduced, this voltage is described as accident-proof The control of the heating power, on and off times are determined by the parameters of the sensors described below

As a further variant of the power supply, an accumulator with 48V, 24V or 12V is used and that if no power supply available / st or a service provider offers the mat system as a winter service a z B caretaker or owner The battery variant can also, if it

SUBSTITUTE SHEET (CONE 26f Allow environmental conditions at the place to be set up, be supplied by a solar panel with sustainable energy This variant of the operation of the system is the most desirable, since sustainable energy is used and the accumulator serves as energy storage

Regardless of which version of the infeed is used, the heating power and the time of heating or deactivation must be controlled by a control unit. The parameters for the control are provided by the temperature, humidity and water sensors. Only these parameters ensure that the heating mat system In addition, the control unit should also have a timer and a manual on / off function to keep the open spaces at the legally prescribed times, snow and ice free, should the probes fail due to a defect The sensors and control units used for this purpose are already used for free-standing heating systems, which are, however, in screed or mastic asphalt and can therefore be adapted to our system. The control unit should be placed directly on one of the mat connections, since the feed point is thus protected against unauthorized access In addition, the control unit is attached either to the building wall or to the subsoil, in order to prevent the theft of the same. If larger mat composites make it necessary to supply further feed points, this is possible at any time

The one or more solar panels should be mounted so high on a trestle that, first of all, passers - by do not bump into it, and secondly, it is out of the reach of passers - by. The commercial panels should be oriented according to the manufacturer 's instructions to ensure optimum power efficiency generated solar energy for the case of need

Through the design of the connection elements and the different Matsausfuhrungen any kind of surfaces whichever flat shape can be heated by stair elements, corner areas, crossing areas, etc, also any surface composite can be heated, since the connection positions no matter what kind of mat dimensions or types of mats (crossing mat , Stair mat, etc) are always fit to each other By this fit accuracy superfluous wiring to feed device, which of course has the same matching connections, can be avoided

The fasteners listed here, are adapted to the different substrates Where, in the underground may and may be drilled, (preferably commercially available) internally threaded recesses sunk and screwed with the mounting screws through the eyelets in the mats Where can not or may not be drilled , For example, in stairs made of natural or artificial stone, a (preferably commercially available) internal thread sleeve is glued to the substrate (preferably with a Verbundmortel), then a fine-threading sleeve is connected through the eyelets with the female thread In the substrates, where it is not possible for drilling or gluing, eg for gravel paths, lawnstones, the fixing pin (28) is used, which is hammered into the ground through the eyelets in the mats. All mounting options and eyelets should preferably be made of galvanized steel or a comparatively weather-resistant material

The geometry of the mats used is designed so that the mats are flattening to the edges and marked with a preferably black and yellow striped band or paint order, firstly the Passers-by to point out that now the mat starts or ends and secondly to reduce the risk of tripping

The preparation of the mats should preferably be made by sandwiching, wherein the mat should consist of a base mat with bevelled sides, the heating elements are placed on it and then preferably the smaller marked at the edges deck mat is glued or vulcanized with the conductors and the base mat Preferably, the (preferably made of galvanized steel) eyelets are punched through the mat and the connectors are attached to the cable outlets A possible imprint can now be applied to the mats, for example, to increase security and / or to apply an advertising print
