DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention concerns sectional framing and sectional insert, whereby one contact surface on the insert rests against the framing, the insert has a flange with a foot-shaped cross-section that extends into a channel with a C-shaped cross-section, the flange has an impact surface that extends perpendicular to the contact surface and rests against the wall of the channel, and the flange has a snap-in edge that engages below and can be released from the head of another wall that has a T-shaped cross-section and is positioned opposite the first wall.
Known sectional framing of this type is described in German Patent 1 509 900. A resilient two-flanged positioner has a base that fits into an accommodation for a pane of glass in the framing. A lateral extension of the base slopes up and is tensioned into a longitudinal groove in the insert. The description implies that the base supports the pane and prevents it from coming into contact with metal.
Experience with the aforesaid resilient positioner, however, reveals that its upward sloping lateral extension complicates glazing to the extent that the extension cannot as intended be inserted into the C-section channel in the framing before the glass is positioned but only afterward. The known positioner is accordingly unable to support the pane as intended and must even be unwieldily forced in under the pane in order to secure it in the framing. In the case of already assembled frames, again, all the positioners must initially be removed from the framing again at the beginning of the glazing process, which entails additional assembly expenditure even if they do not become mislaid at the site.
SUMMARY OF THE INVENTION
Given these drawbacks, it is the object of the invention to provide framing wherein, in order to eliminate glazing problems, the resilient positioners are associated with the insert instead of with the framing and can accordingly easily be fitted already secured to the insert into the framing or removed therefrom when necessary. Another advantage of this approach is that the correct number and type of positioners as dictated at the factory will always be available, ensuring that they will fit tight into the framing. Finally, considerably less material will be needed for the resilient positioners.
The particular design that attains this object is characterized in the claims. In accordance with the major feature of the new framing, accordingly, the positioners at least partly enclose the inserted area of the snap-in edge of the foot-section flange, are inserted into a longitudinal snap-in groove, and have resilient tongues above the snap-in edge that rest subject to tension against the head of the T-section wall. Advanced versions of the invention represent perfections with respect to how the invention is mounted and functions.
Some embodiments of the invention will now be described by way of example with reference to the cross-sections illustrated in the figures.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a partial sectional view of the frame and insert, in accordance with the present invention;
FIG. 2 is a partial sectional view of another embodiment of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
As will be evident from the figures, each length of sectional framing 1 is associated with a length of sectional insert 2. Insert 2 secures a pane 3 of insulating glass in framing 1 by means of a sealing strip 6 between the free side 4 of the insert and pane 3 and by means of another sealing strip 7 between the free side 5 of framing 1 and the pane.
One contact surface 9 on insert 2 rests against the undercut wall 10 of a channel 11 with a C-shaped cross-section. Insert 2 also has a flange 12 with a foot-shaped cross-section that extends into channel 11. Flange 12 has an impact surface 13 that extends perpendicular to contact surface 9 and rests against the wall 10 of channel 11. Flange 12 also has a snap-in edge 14 that engages below the head 15 of another wall 16 that has a T-shaped cross-section and is positioned
