Definitions

• the invention relates to a door and a method for manufacturing a door comprising a first outer layer, a second outer layer and an insulating layer therebetween and also a decor unit.
• Door compositions comprising a decor unit in the shape of a unit of glass are previously known.
• the unit of glass is mounted in one in the door existing through-and-through opening.
• a number of layers are mounted together to a door where after the opening is made, for instance through milling.
• layers of which the door comprises have already been processed in such a way that openings are made in the material, which leads to that the through-and- through opening is formed during the assembly of the door as the different openings are fitted against each other.
• the unit of glass can have different geometrical designs, for instance round, oval, triangular, square or polygonal. This leads to that the through-and-through opening in the door has to be designed with the same geometrical cross section.
• a common problem with the previously known techniques is that the unit of glass is attached with a strip which is in contact with the outside of the door and the outside of the unit of glass.
• the strip has to be adjusted in such a way that water and wind does not penetrate the unit of glass and the door.
• the strip has to anchor the unit of glass in such a way that the unit of glass is not easily removed from its attachment by an unwanted visitor wanting to break in.
• it is furthermore difficult to simply manufacture a strip that follows the contour of the geometry and at the same time fulfils the demands for impenetrability, security and aesthetics.
• the invention intends to eliminate the above mentioned problems through an improved method for arranging a decor unit of a door.
• the invention relates to a door comprising a first outer layer, a second outer layer and an insulation layer therebetween and also a decor unit.
• the invention is characterized by that the decor unit is arranged between the first outer layer and the second outer layer, whereupon the decor unit is exposed in a first opening of the first layer, where the decor unit has a larger area than the first opening.
• An advantage of the invention is that the previously used strips holding the unit of glass/decor unit in place are made redundant as the decor unit is firmly arranged between the first and the second outer layers.
• a decor unit with a geometrical shape can be used for several different geometrical designs of the first opening.
• a rectangular decor unit can be used despite that the first opening is oval, triangular, round or consists of several openings, as long as the first opening does not extend beyond the decor unit.
• the door comprises a first inner layer between the first outer layer and the decor unit, where the first inner layer is in contact with the decor unit.
• the first inner layer constitutes a sealing unit between the decor unit and the first outer layer.
• the first outer layer comprises the first opening before the door's different layers are assembled and according to another embodiment the first opening is made after that the constituting layers of the door are assembled forming the door.
• Both embodiments admits the advantage of that the previously known strips can be eliminated.
• the first opening can be designed independently of the decor unit. As an example can be mentioned that the decor unit is square and the first opening is desired to be oval, then the only limitation is that the first opening is not larger than the decor unit and that the first opening shall be placed within the decor unit's perimeter/delimitation boundary.
• the first opening shall according to the invention be formed through that the corresponding part of the first outer layer is removed before and separately from the removal of the first inner layer.
• the decor unit is exposed in a second opening of the second outer layer, where the decor unit has a larger area than the second opening.
• the second opening can be arranged in the same way as the first opening.
• the door comprises a second inner layer between the second outer layer and the decor unit, where the second inner layer is in contact with the decor unit.
• the second inner layer can have some or all of the functions mentioned with regard to the first layer.
• An advantage of the invention is that a decor unit with a geometric shape can be used for several different geometric designs of the first opening or the second opening.
• a rectangular decor unit can be used despite that the first and second opening is oval, triangular, round or consists of several openings, as long as the first opening or the second opening does not extend beyond the decor unit.
• the decor unit can thus be mass produced in an uncomplicated and inexpensive geometry and the first opening and/or the second opening can then be chosen to have a similar uncomplicated design or to have a complicated pattern.
• Then invention also relates to a method for manufacturing a door according to the description above.
• the method has the advantage of that strips are not required in order to keep the decor unit in place and that one size of the decor unit can be used for different designs of the first and/or second opening.
