BRIEF SUMMARY
DESCRIPTION
The present invention relates to a floor-mounted door closer device of the type specified in the preamble of claim 1. Such a floor-mounted door closer device is of customary design as described in DE 3937262 A1, for example.
In the floor-mounted door closer devices which have been used hitherto, the cover plate for covering the floor cavity receiving the floor-mounted door closer device bears on the flooring material surrounding the cavity, i.e. the cover plate constitutes a projection from the flooring material. This makes the floor difficult to clean in the vicinity of the floor-mounted door closer device. The cover plate is made of a metal, such as aluminium, steel or brass, and although attempts have been made to give the surface of the cover plate a visually attractive design, e.g. of anodised aluminium, the cover plate nevertheless always constitutes a visual interruption of the surface formed by the flooring material. In addition, wear or environmental influence, for instance abrasion and oxidation, often cause changes in color, mainly affecting the edges of the cover plate.
This can impair the visual overall appearance of the door provided with the floor-mounted door closer device, if for example the door is made entirely of glass and substantially no materials other than the door glass and flooring material are supposed to be visible.
The object of the invention is to design the cover means of a floor-mounted door closer device of the abovementioned type such that the visual overall appearance provided by the flooring material in the area of the floor-mounted door closer device is only interrupted and impaired to the smallest extent possible.
According to the invention, the object is achieved by the features of claim 1. The dependent claims concern further advantageous embodiments of the invention.
The cover of the floor-mounted door closer device according to the invention has an upper surface consisting of the same material as the surrounding flooring material and is substantially flush therewith. This arrangement accomplishes the visual appearance of a jointless flooring material which is continuous even in the area of the floor-mounted door closer device. Cleaning of this floor area is facilitated, and subsequent color changes will not occur or will occur only to the same degree as in the adjacent flooring material.
According to a preferred embodiment of the invention, the cover plate comprises reinforcing means, in particular if the cover plate is arranged as a flat rectangular box open on its top side. As an alternative, the cover plate can be borne by a stable supporting plate arranged beneath the cover plate and supporting substantially the entire surface of the latter, this feature being known as such from DE 3937262 A1 already referenced above. According to the invention, however, this supporting plate is designed as a flat box open on its top side, in which the cover plate is detachably inserted.
In order to allow the cover plate and, as the case may be, the supporting plate to be inserted and taken out without having to detach the door from the pivot pin of the floor-mounted door closer device, the cover plate and, as the case may be, the supporting plate are divided, i.e. assembled from two pieces, in the region of the through-hole for the pivot pin, various ways of implementation being possible for the type of this division within the scope of the invention.
