In the embodiment shown, in which the flange 22b is-manufactured in one piece as a monoblock with the part 22a, the flange is positioned on the first cylindrical part 37 and more particularly near the wall 39.
The first cylindrical part 37, inside, forms a bearing for the outer surface of the shaft 10, which passes through the piece 22.
The wall 39 is intended to abut against or substantially against the second wing 26 in the space 36.
As for the second cylindrical part 38, housed partly in the space 36, partly above, its outside forms a bearing for the cylindrical internal face of the drum 12.
Additionally, the second cylindrical part 38 also forms, this time inside, a housing for the ring 20.
It is understood that the term « bearing » and the corresponding tolerances must be considered relatively depending on the type of application considered.
The structure described is such that the axial dimensions of the mechanism are limited, since the latter does not protrude outside the door 2.
Positioning operations are carried out as follows:
The support pieces 21 of the two assemblies are intended to be suitably fixed to the doorframe by means of the folded back return wing 27 which forms a fixing plate, and the appropriate screws or bolts.
Besides, the pieces 22, on each side of the shaft 10, are positioned and supported by the cradle 29 of the two support pieces 21.
~ rig a iil zlll Immobilisation is achieved by means of the flanges 22b and the fixation means 23.
The first extreme part 16 of the spring 15 is immobilised by being interposed between the support piece 21 and the piece 22 in the notch 34.
The notch 34 is therefore of a size and shape adapted to, more pazticularly complementary to, the size and shape of the extreme part 16.
In the embodiment considered the extreme part 16 is bent back into a hook manufactured in one piece, the hook coming behind the second wing 26.
Consequently, it is not necessary to provide, as was conventionally the case, for an added piece in the form of an immobilising ring specifically - intended for the immobilisation of the first extreme part 16.
Thanks to the mounting structure described, the balancing mechanism can thus be pre-assembled and pre-adjusted, in particular in the factory or as part of after-sales service.
Furthermore the balancing mechanism can be assembled and disassembled from the front in the embodiments described, using the fixing devices 23 of the flange 22b to the support piece 21, which makes for great ease of use.
In addition, the fixation of the mounting 9 to the doorframe of the construction which is to house the door allows this mounting to be pre-mounted, as against fixing directly to the masonry which calls for a lengthy installation time and adjustments, especially of alignment.
The first cylindrical part 37, inside, forms a bearing for the outer surface of the shaft 10, which passes through the piece 22.
The wall 39 is intended to abut against or substantially against the second wing 26 in the space 36.
As for the second cylindrical part 38, housed partly in the space 36, partly above, its outside forms a bearing for the cylindrical internal face of the drum 12.
Additionally, the second cylindrical part 38 also forms, this time inside, a housing for the ring 20.
It is understood that the term « bearing » and the corresponding tolerances must be considered relatively depending on the type of application considered.
The structure described is such that the axial dimensions of the mechanism are limited, since the latter does not protrude outside the door 2.
Positioning operations are carried out as follows:
The support pieces 21 of the two assemblies are intended to be suitably fixed to the doorframe by means of the folded back return wing 27 which forms a fixing plate, and the appropriate screws or bolts.
Besides, the pieces 22, on each side of the shaft 10, are positioned and supported by the cradle 29 of the two support pieces 21.
~ rig a iil zlll Immobilisation is achieved by means of the flanges 22b and the fixation means 23.
The first extreme part 16 of the spring 15 is immobilised by being interposed between the support piece 21 and the piece 22 in the notch 34.
The notch 34 is therefore of a size and shape adapted to, more pazticularly complementary to, the size and shape of the extreme part 16.
In the embodiment considered the extreme part 16 is bent back into a hook manufactured in one piece, the hook coming behind the second wing 26.
Consequently, it is not necessary to provide, as was conventionally the case, for an added piece in the form of an immobilising ring specifically - intended for the immobilisation of the first extreme part 16.
Thanks to the mounting structure described, the balancing mechanism can thus be pre-assembled and pre-adjusted, in particular in the factory or as part of after-sales service.
Furthermore the balancing mechanism can be assembled and disassembled from the front in the embodiments described, using the fixing devices 23 of the flange 22b to the support piece 21, which makes for great ease of use.
In addition, the fixation of the mounting 9 to the doorframe of the construction which is to house the door allows this mounting to be pre-mounted, as against fixing directly to the masonry which calls for a lengthy installation time and adjustments, especially of alignment.
