Sliding door, meant especially to be used in fire protection or insulation

Sliding door, meant especially to be used in fire protection or insulation, whereby the sliding door comprises a framework consisting of a number of profiles on which framework panels are attached.

Sliding door, meant especially to be used in fire protection or insulation. 
The invention relates to a sliding door, meant especially to be used in 
fire-proof, sound-proof or thermal insulation. Such sliding doors must be 
mounted hermetically against a doorcase construction. For this purpose, 
the sliding door must have a rigid contruction, which usually consists of 
a beam- and lath-construction which is put together unshrinkably by means 
of glue or screws and which as a front and a rear panel between which 
insulation material is provided in dependence on the use of the sliding 
door. Particularly with large sliding doors, this presents the 
disadvantage that these constructions are difficult to handle and 
transport, among other reasons because of their weight. Especially when 
long distance transportation is required, as in the case of export, these 
disadvantages become unacceptable. 
The purpose of the present invention is to provide a sliding door, meant 
espcially to be used in fire-proof, sound-proof or thermal insulation, 
which can be prefabricated as a construction set in a workshop and which 
can be put together easily at the building-site. 
For that purpose, the sliding door according to the invention is 
characterized in that the sliding door comprises a framework consisting of 
a number of profiles, on which framework panels are attached. 
Such a construction offers the advantage that the entire construction can 
be prefabricated in th right dimensions at the factory, whereafter 
transportation as a construction set is simple, whereas the assembly at 
the building-site is possible in a simple manner, and yet a sliding door 
is obtained with sufficient rigidity to guarantee an hermetic sealing 
against the doorcase of the sliding door. 
A favourable embodiment of the sliding door according to the invention is 
characterized in that the profiles are metal profiles, which at the top 
side of the door are connected to one another by corner pieces, whereas at 
the underside the profiles are connected to one another by a under guiding 
profile. 
A further favourable embodiment of the sliding door according to the 
invention is characterized in that the panels are clamped against the 
profiles by means of corner profiles. 
Another favourable embodiment of the sliding door according to the 
invention is characterized in that a rubber sealing profile is clamped 
between the panels and the corner profiles.

In the drawing the profiles are indicated by the reference numbers 1, 2 and 
3, whereas the under guiding profile 4,5 at the under side is attached to 
the profiles 1 and 3 by means of screws. At the top side the profiles 1 
and 2 are connected to one another by means of a corner piece 6 and the 
profiles 2 and 3 by means of a corner piece 7. On the thus obtained 
framework, panels 8,9,10 are attached, which panels are sealed against one 
another in a simple, known way. The panels are clamped on the framework by 
means of corner profiles 11, 12 and 13. Between the corner profiles and 
the door panel, a sealing profile 14, consisting e.g. of rubber, is 
clamped. At the top side of the thus assembled sliding door, a wheel 
bracket 15 is attached at each corner to the profile, with guiding wheels 
16 and 17. 
It will be obvious that the invention is not restricted to the above-given 
example of an embodiment, but that numerous modifications are possible, 
all within the scope of the invention.
