Abstract

A profiled hinge joint comprises joint wings designed in the form of profiled frame members. One joint wing is provided with a bead member (6) extending longitudinally with the frame member, the other joint wing has a partially open, cap-shaped flange (11) engaging the bead member; said joint wing likewise extends longitudinally with the frame member. The bead member (6) on the side remote from the frame member has been provided with a partially restricted part (18) and the cap-shaped flange (11) possesses a slot of a width such, that the bead member (6) is to be laterally inserted into the cap-shaped flange (11) with an angle outside the hinging field of both frame members.

Description

The invention relates to a profiled hinge joint having joint wings in the form of first and second U-shaped and profiled frame members, said first U-shaped frame member being provided with a flange carrying a bead member of partly circular cross-section and having a restricted portion in its cross-section extending longitudinally of the frame member, said second U-shaped frame member having a channel-shaped curved part extending longitudinally of this frame member, which channel-shaped curved part embraces said bead member.
These profiled hinge joints, mostly made of extruded aluminium, are used for sectional door structures and the like and are so designed that the panels can hinge with respect to each other when the door structure is opened and closed, both ends of the panels being guided in guide tracks which are laterally positioned of the door opening.
To facilitate the installation of a door structure, the profiled hinge joint is so designed that the panels can be hooked into each other when the panel to be hooked in, is in a position outside of the range of hinging when the door structure is used.
Such a hinge joint is known from the DE-A-1 509 191. In this known profiled hinge joint U-shaped frame members are used with the open side directed towards each other. The bead member and the channel-shaped curved part are positioned at the free ends of the lateral flanges of the frame members with the result that the parts hooked together are positioned at the weakest place of the hinge joint. This means that no long panels can be used as parts of the hinge joint come apart when the door is subjected to the wind pressure during opening or closing of the door. Further the parts of the hinge joint come apart during opening of the door as a result of bending of the panels when they reach the horizontal part of the guide tracks above the door opening. Further the upright flanges of the frame member form a space in which rain water and snow can accumulate, which snow can melt for instance by warming up of the door by the sun and during the night the melted snow will become a frozen block preventing the door from opening.
It is an object of the present invention to so improve the construction of a profiled hinge joint that relatively large panels are easily capable of engaging each other and which will withstand wind pressure and bending of the panels without the possibility of the frame members coming apart. Another drawback of this known hinge joint is that no sandwich filling panels made of two plates spaced apart by foam material, can be used in connection with the hinge joint without any auxiliary profiles for fastening the hinge joint to such panels.
It is a further object of the present invention to so improve the construction of a similar profiled hinge joint that sandwich panels can be easily fixed to the frame members and that the frame members will withstand bending forces without coming apart of the frame members. According to the present invention this object is obtained by utilizing a profiled hinge joint of the type as described hereinbefore and is characterized in that the flange is located at the corner of the first U-shaped frame member between a web or central part and a lateral flange of this U-shaped frame member, which flange is inclined away from the plane of said lateral flange towards said web and the bead member has its restricted portion in its outer wall at the junction between the bead member and the outer inclined surface of the inclined flange and that the channel-shaped curved part is situated at a corner of the second U-shaped frame member between a lateral flange and a web or central part of the second U-shaped frame member, which web abuts on the adjacent web of the first U-shaped frame member when the lateral flanges of both U-shaped frame members are in alignment with each other. This presents the advantage that when the frame members are in alignment with each other the webs or central parts of the frame members are adjacent and abut each other and no sand or snow can enter the hinge joint. Further, sandwich panels can be easily inserted between the flanges of the U-shaped frame members and the hinge joint has a large resistance to bending either by wind forces or by bending of the panels when they enter a horizontal part of the guide tracks.
From US-A-2,880,796 a profiled hinge joint is known in which the frame members have parallel flanges extending in the direction of the panels of a door and a sandwich panel comprising two plates and foam material therebetween can be inserted into the space defined by the parallel flanges. However, the bead member and the channel-shaped curved part extends in a space between the webs of central parts of the frame members. Additional flanges are provided on the webs in order to close the space between the webs. However as soon as the panels hinge with respect to each other snow can enter in the space between the webs and additional flanges. Further the channel-shaped curved part extends from the web of the frame member and as a result of which it does not have sufficient resistance against the forces which occur when the panels of a door are pivoted to enter the horizontal part of the guiding tracks and the frame members can come apart. For this reason the width of the door is limited and no large panels can be obtained with such a hinge joint.
According to the invention a practical embodiment of the profiled hinge joint is characterized in that a retracted curved wall is formed as a connection between the web and a lateral flange of a U-shaped frame member.
The invention relates also to a door divided transversally into panels capable of relative pivotal movements about axes along the lines of division and the adjoining panels are connected to each other by a profiled hinge joint according to the invention, which door is characterized in that the adjoining webs of the U-shaped frame members abut against each other and the bead member and the channel-shaped part are positioned in a space between the adjoining webs and the adjacent lateral flanges of the U-shaped frame members when the panels of the door are in alignment with each other. Further a door according to the invention may be adapted for mounting between guiding tracks of inwardly faced channel sections and each panel has been provided with a guide roller for each track. Such a door is characterized in that the guide roller has its shaft mounted within a hole in the bead member of the hinge joint and cooperates with a first flange of the guiding track spaced from a second flange, the flange cooperating with the guide roller being shorter than the second flange to permit a lateral insertion of the panels with a guide roller.
The invention will now be illustrated by way of example with reference to the accompanying drawings, in which:

Figure 1 is a perspective view of a lifting door provided with profiled hinge joint members in accordance with the invention;
Figure 2 is a cross-sectional view of a profiled hinge joint as disposed between two panels of the lifting door shown in Figure 1;
Figure 3 is a strongly enlarged, cross-sectional view of a detail in Figure 2;
Figure 4 is a plan view of a profiled hinge joint member mounted in a lifting door, having a roller in a guide rail;
Figures 5-8 are sectional views, as shown in Figure 3, wherein the joint wings are in different positions with respect to one another, and
Figure 9 is a section, identical to the one in Figure 2, wherein a roller has been mounted in the hinge joint member.

In the case of lifting doors, which do not have enough space above the door opening, guide rails are used which are curved above the door, in the door then being composed of panels 1 being hingedly attached to each other. At the location of the hinge joints there are mounted on the side edges of the doors, rollers 2 which are adapted to fit into the guide rails 3a and 3b.
As is clearly visible in Figure 1, the guide rails 3a and 3b change into a curved portion mounted to the ceiling or other holding means. On lifting the door, the panels 1, while moving, assume different positions with respect to one another until they have arrived in the curved portion when the door has been opened completely.
To this end the panels 1 are provided with profiled hinge joints in the form of a profiled lower frame 4 and a profiled upper frame 5.
The manner in which the door is elevated, for example by means of a drive mechanism, will not be described as this does not form part of the subject matter of the present invention.
The lower frame 4 is provided with a hollow bead member 6, being connected with a side flange 7 of the frame 4.
The bead member 6 is disposed stepped relative to the flange 7 by being formed integral with an inclined flange having a slanted area 17 (Fig. 3). A portion of the outer wall of the bead member 6 has a restricted area for a purpose to be described hereinafter. This restricted portion or recess is referenced 18 in Figure 3. The radius of said recess 18 runs from a centre differing from that of the radius of the remaining portion of the bead member 6. In addition, the bead member 6 is in longitudinal direction provided with a bore 19 for receiving a pin 20 of a roller 2 (Fig. 4).
The bead member 6 is surrounded by a shell 8 forming the connection between the flange 7 and the flange 9 of the frame 4. A chamber being open at the location of the flange 9, vide in particular Figure 3, is thus formed around the bead member 6.
A channel-shaped flange 11 of the profiled frame member 5 is adapted to fit around the bead member 6 and in the chamber 10. Said channel-shaped flange 11 is located between two flanges 12 and 13 of the frame member 5 which are disposed at an angle with respect to each other.
The channel-shaped flange 11 has a relatively large, open portion so as to enable the frame member 5 to engage the frame member 4 while still ensuring an adequate supporting function of the channel-shaped frame 11, since the latter fits with its inner wall 14 around the bead member 6 and rests with its outer wall 15 against a wall 16 of said chamber 10.
When positioning a panel 1 between the rails, its channel-shaped flange 11 is disposed upon the bead member 6 and slid inwards, the pin 20 being pushed tightly with its roller against the frame 5, so that the panel can be pressed between the rails 3a and 3b. Thereupon, the roller with the pin is slid outwards to beyond a flange 21 of the rails 3. The pin 20 is subsequently secured in the opening 19 of the bead member 6 by means of a tension pin or a locking screw.
Figure 5 shows the profiled hinge joint in the situation occurring at the moment when a panel 1 is brought into position above another panel. Firstly the hinge joint is snapped in, whereby the area connecting the channel-shaped flange 11 to the flange 13 will fit in the recess 18 with the slanted section 17, as shown in Figure 6. The channel-shaped flange 11 thus penetrates into the chamber 10 of the profiled frame 4, also because of the chamber 10 having a widened section in the vicinity of the flange 9.
Figure 7, shows that on continuing the swinging movement, the inner wall of the channel-shaped flange 11 comes into a closer position around the bead member, thus detaching the recess 18 from the wall of said channel-shaped flange 11. Thus, the frame members 4 and 5 are positioned with respect to one another, so that they can move in an articulated manner in relation to each other, for example from a square position as shown in Figure 8, to a closed position as shown in Figure 9. The frame member 4 has a shoulder 22 for abutment of the frame member 5. As a result, draught strips 23 can be arranged between the flanges 12 and 9 so that a door comprising panels 1 provides a good, wind-proof seal in a closed position. The roller 2 is then resting against the flange 21 of a guide rail 3a or 3b.
