Description

The The invention relates to a bottom edge termination for a heat-insulated vehicle floor in his door area, its bottom body consisting essentially of a wood-foam composite, on its tread Covered with a floor plate and stiffened, that to the bottom edge bent over is and at the bottom edge ends at a lower level as otherwise Ground level.

The DD 208 589 represents such a bottom edge termination. The disadvantage of the construction shown there is the thermal bridge over the assembled metal components, since the heat on the lower stiffening profile and the screw can get into the interior of the structure.

Furthermore, the shows DE 22 21 486 A a bottom edge termination for a heat-insulated vehicle floor, which is bent in the door area to the bottom edge and ends in the bottom edge at a lower level than the rest of the floor level, wherein a U-shaped, rigid sheet metal body engages over the outer edge of the bottom body at its upper edge, that of Upper leg of the sheet metal body overlaps the bottom in the region of the crank and runs out at the level of the rest of the soil (see. 2 and 6 mentioned font).

It the task is to specify a bottom edge termination, the on a bottom body of the mentioned type is to be connected in a simple manner, which has a high rigidity and gives a high edge protection and in the beyond Thermal bridges largely be avoided.

• – dass ein U-förmiger, steifer Blechkörper die Aussenkante des Bodenkörpers an dessen Ober- und Unterkante derart übergreift,
• – dass der obere U-Schenkel des Blechkörpers das Bodenblech im Bereich der Kröpfung unter Vermeidung einer metallischen Wärmebrücke überlappt und im wesentlichen auf dem Niveau des übrigen Bodenblechs ausläuft und
• – der untere U-Schenkel des Blechkörpers aus einem auf der Unterseite des Bodenkörpers befestigten Blechstreifen besteht, der über die Aussenkante des Bodenkörpers übersteht und dort mit einem U-Element verbunden ist.

This object is achieved by a bottom edge termination for a heat-insulated vehicle floor, which is characterized

• - That a U-shaped, rigid sheet metal body engages over the outer edge of the bottom body at its upper and lower edge,
• - That the upper U-leg of the sheet metal body overlaps the bottom plate in the region of the cranking while avoiding a metallic thermal bridge and substantially at the level of the remaining bottom plate leaking and
• - The lower U-leg of the sheet metal body consists of a fixed to the underside of the bottom body sheet metal strip, which projects beyond the outer edge of the bottom body and is connected there to a U-element.

The cranking of the floor panel is called a Z-turn made and ends, for example, on the surface of a Recess of the wood construction. As material comes in the first place Aluminum in question; however, other typical materials are also suitable, like steel, stainless steel or composite materials.

Therefore a cavity can remain between the U-web of the sheet metal body and the bottom edge; this cavity can also be foamed with a plastic foam, to increase the insulation effect.

Between the upper U-leg of the sheet metal body and the cranked Completion of the Floor panel can be arranged an insulating strip. The attachment of the upper U-thigh with the soil body can force fit by screws or rivets, whereby by appropriate Construction a thermal contact between bottom plate and the sheet metal body is largely avoidable.

Of the lower part of the sheet metal body is attached at the bottom to a on the bottom of the bottom body, over the Outer edge of the soil body protruding Metal strips connected, preferably screwed.

Around a thermal bridge-free, however, the heat movements absorbing transition from the floor panel to the edge of the upper U-leg, becomes a sealing, elastomeric between these two parts Strip inserted, for example, from a permanently elastic silicone mass or as a section of a durable rubber profile.

One embodiment The invention is shown in the figure.

The Figure shows a section through a bottom edge termination for a thermally insulated Vehicle floor.

In the figure is a bottom body 1 recognizable, which consists of a wood foam plastic structure of known type. Visible are two continuous plywood stands 2 . 2 '; those on their bottom on a floorboard 18 get up and on top with a deck board 4 are covered to the edge (edge area 4 ' ) is graduated. The free top of the soil body 1 is from a floor panel 5 , For example, an aluminum-Gestenkornblech covered. The bottom plate stiffens the ground and is bent to the bottom edge (crank 6 ) and lies partially on the top of the stepped edge portion 4 ' of the top board.

Below the floorboard is over an adhesive layer 20 a metal strip 16 glued over the outer edge of the bottom body 1 above stands. In the supernatant area 16 ' is the metal strip 16 At intervals provided with holes through which strong screws protrude. With the help of these screws 19 are two substantially superimposed parts, namely an inner U-part 13 and an outer U-part 14 , connected to the metal strip.

As can be seen, the outer U-part is running 14 up into an upper U-leg 15 off, the floor panel 5 in the area of the bend 6 while avoiding a metallic thermal bridge overlaps and substantially at the level of the rest of the floor panel 5 expires.

The parts 16 . 13 . 14 , and 15 together form a U-shaped, rigid sheet metal body 10 , which engages over the outer edge of the bottom body at its top and bottom. Between the upper U-thigh 15 and the edge area 4 ' of the cover board 4 remains a distance that is filled with an insulating strip, such as glass fiber reinforced plastic. With the help of thermal bridges rivets 22 becomes the upper U-leg 15 with the edge area 4 ' positively connected. The insulating strip 21 is inserted in a bedding of the end area 8th of the floor panel 5 that from a nose 7 is limited.

The sheet metal body 10 is with his U-element 11 so far from the outer edge of the soil body 1 spaced that a free space remains. This free space can either remain air-filled; Preferably, however, it is filled with a plastic foam. (Plastic foam filling 17 ). For this purpose, known polystyrene or polyurethane foams are suitable, as they already for the known foam areas 3 . 3 ' have been used.

Between the inner edge of the upper U-leg 15 and the craning area 6 of the sheet 5 is a sealing elastomeric strip 24 pressed in, which prevents the inflow of liquid and represents a compensating element for thermal movements.

Furthermore, before the threshold 25 a drainage pipe 9 placed, which is passed through the bottom body and ends below the bottom body. Further, the bottom body 1' still with a stiffening profile 30 provided, as is known. The stiffening profile 30 is with screws 19 held on the rest of the bottom edge termination. The bottom edge termination is used, for example, to consolidate the rear edge of the vehicle.

Above the bottom edge termination ends the rear wall door 26 that with two strong sealing lips 27 . 28 ends down. The inner sealing lip 27 presses on one of the inner edge of the upper U-leg 15 attached threshold 25 , which may for example be bent from a rubber profile and glued to the thigh.

The outer sealing lip 28 presses simultaneously against the U-element. The back door 26 is thus made air-tight and moisture-tight from the inside and outside, so that, for example, no dripping blood or condensation of interior or spray water from the outside reach the door area or penetrate the rear wall door.

Furthermore, vehicle lights, lashing elements 23 or similar elements easily with the sheet metal body 10 externally connected.

All in all thus provides the bottom edge termination a reliable and especially for thermally insulated vehicle floors constructively convincing solution the task at the beginning.
