Problems solved by technology

[0003] Although the added part can be reliably attached to a base surface with existing fastening devices, unless the melting conditions of the hot-melt adhesive are strictly observed, there is some risk: if the initial melting temperature is too low, Then the hot melt adhesive will not adequately bond to the planar outside surface and may crumble during, for example, shipping the fastening device as a bulk cargo; or if the initial temperature is too high, then Hot melt adhesives are activated here and there and the fixation achieved is not sufficient to create an adhesive bond between the fastening device and the substrate when they are joined

Embodiment Construction

[0015] figure 1 is a perspective sectional view of a first exemplary embodiment of an inventive fastening device, comprising a fastening element 1 for which an elongated shaft-like portion 2 and a flattened annular plate 3 of circular circumference are provided as fastening parts, The flattened annular plate 3 is connected to the shaft-shaped part 2 . The annular plate annular plate shaft portion 2 is configured as elongated and acts as a fastening additional part, not shown in figure 1 However, the annular plate 3 has an outer surface 4, which is planar in this exemplary embodiment, facing oppositely to the shaft-like portion 2, and from the edge region of this outer surface, a plurality of spacers 5 protrude from the surface 4 Protrude upward.

[0016] Arranged approximately in the center of the annular plate 3 is a receiving groove 6 which opens in the direction of the planar outer surface 4 . The receiving groove 6 has a flat inner bottom wall 7 and a circular periphera...

Abstract

A fixing device comprises a fixing part(1)consisting of a fixing section(3)provided with a planar outer-sided surface and a melt adhesive which can be melted in order to fix the fixing part(1)to a base plane. The fixing part(1)is provided with a receiving recess(6)which is open in the direction of the planar outer-sided surface(4). The melt adhesive is embodied as a pressed part(11)whose shape is adapted to the fixed structure(8, 9; 14; 15, 16, 18; 20, 21)such that the pressed part(11)can be joined to the fixing part(1). As a result it is possible to pre-manufacture the fixing device without melting the melt adhesive.

Description

technical field [0001] The invention relates to a fastening device according to the preamble of claim 1 . Background technique [0002] Such a fastening device is known from DE19645000A1. Known fastening devices include a fastening element with a fastening portion having a planar outer surface. The fastening device is also provided with a hot-melt adhesive that adheres to the planar outside surface as a sticky layer after partially melting at a relatively low temperature and melts at a relatively high temperature to a base surface, thereby fastening the fastening device thus prefabricated. [0003] Although the added part can be reliably attached to a base surface with existing fastening devices, unless the melting conditions of the hot melt adhesive are strictly observed, there is some risk: if the initial melting temperature is too low, Then the hot melt adhesive will not adequately bond to the planar outside surface and may crumble the fastening device during, for exam...
