Description
~2~03~9 This invention relates to an overhead swinging door, particularly to a garage door or the like.
It is typical for many doors of t'nis type that, on opening, the bottom edge of the door panel does not, in effect, swing from the plane defined by the closed door panel. This feature is a standrdized requirement in many countries. The problem occurring here is in that conventional door panels are not sufficiently rigid for their purpose, so that w'nen operating the panels difficulties ariseO To make such a door panel more rigid, a type of swinging door is known from our West German Utility Model 72 38 251, published February 15, 1973, wherein guiding rollers or pulleys are installed at the ends of a common shaft extending across the entire width of the door panel. The door panel has consequently an increased resistance to twisting forces. These known door panels may be satisfactory if the door panel is held and manipulated approximately at the center of its width.
However, when a user takes hoLd of this door panel at a point away from the center, the panel immediately tends to go out of alignment and consequently jams because the parallel run of the guiding pulleys is not sufficiently secured to the guiding surfaces.
It is an object of the present invention to provide an overhead swinging door, particularly for garages, which would be of a simple structure and would be reliable in operation when the panel is being closed or opened, without misalignment and the consequent jamming.
In general terms, the present invention provides an overhead swinging door comprising, in combination: a door panel; spring-loaded lever means adapted to support said door panel; guide roller means disposed at each side of the door panel near a normally lower edge thereof;
generally straight, normally generally vertical guide surface means adapted to guide the guide roller means as the panel is moved from a closed to an open state; said ~2~;~3~
lever means having a first end pivotably secured to said panel at a generally central portion thereof, the other end of the lever means being pivotably secured to said guide surface means near a normally upper end thereof;
first cable means, a second cable means generally coincident with a first and a second one of the guide roller means, respectively, and a cable pulley system for guiding said first cable means and said second cable means; said cable means including cable securement means for securing respective ends of each of the cable means to the panel near the respective guide roller means thereof;
said cable pulley system including a plurality of pulleys adapted to become so arranged and disposed that they are capable of guiding the first cable means in a direction generally vertically downwardly from a first one of the cable securement means, then generally vertically upwardly towards a first upper corner of an associated door opening, then towards a second upper corner o-f an associated door opening and then generally vertically downwardly towards a second one of the cable securement means, while the second cable means is guided in a direction generally vertically downwardly from the second one of the cable securement means, then generally vertically upwardly to the second upper corner, then to the first upper corner and then generally vertically downwardly to the first one of said first cable securement means.
The invention will now be described by way of a preferred embodiment with reference to the accompanying simplified, diagrammatic drawings, wherein:
Fig. 1 is a diagrammatic cross-section of a swinging door of the present invention in an assembled state;
Fig. 2 is a rear view in the direction II-II of Fig. l;
Fig. 3 is detail III of Fig. 2 shown in a cut-off fashion and on an enlarged scale; and ~'~
3~
Fig. 4 shows the part of the cables shown in Fig. 2.
When fully assembled, the overhead swing door, referred to in general ~ith reference number 5, is S disposed in the area of a door opening in a building 6 and is provided with a door frame 7 consisting of two vertical sections 8 installed at a distance from each other and of a horizontal portion or ~section 9, which connects both of sections 8. A door panel or leaf ll is held by a spring-loaded ]ever and is shown here in a partly opened state. One end of each of levers lO holdsj the respective side of the panel ll at approximately the mid-height thereof; the other end of each lever 10 is pivotably secured, near the upper end of the respective vertical section 8 of the door frame.
Furthermore, the door panel 11 is provided with guide rollers 12 laterally protruding over the panel. The shafts 13 (Fig. 3) of these rollers are coaxial and are guided on guide surfaces 14 formed in the vertical sections 8 of the door frame 7, and facing the interior of the garage. In an open state, the rollers 12 are simply supported each on its respective guide surface, the open position being shown in broken lines of Fig. l.
Fig. 2, on the other hand, shows the swinging door 5 with the closed door panel 11 as viewed from the interior of the building S; here the lever 10, for si~plicity, is not completely dLawn but is shown as if broken-off, Furthermore, the lock 15 is shown with a pair of locking rods 16 and bolts I7.
The greater detail presented in Fig. 3 shows the guiding roller 12 mounted at a lower part of the door panel 11. The shaft 13 is mounted in the guiding pulley bearing 18 and protrudes laterally over the side contour of panel ll. It is evident that the shaft 13 of the guiding roller 12 is horizonthl and coincides with the plane of the door panel ll. On the shaft 13 are shown 3~9 loop-shaped ends 19, 20 of the two cables 21, 22, the part of whic'n will now be described in greater detail with reference to Fig. 4.
The first cable 22 is ln its first part or first component portion _ parallel to a guiding surface 14 and extends vertically upwards, then is deflected 90 by an upper guide pulley 28 mounted in the area of one upper corner 27 of the door frame 7. From there on, the cable 22 continues in a second section parallel to the horizontal section 9 of the door panel 7 generally horizontally to the second upoer guide pulley 29 arranged in the area of the second upper corner 27 of th~ door frame 7. At the latter it is again deflected 90 so that in the third section or third component portion 25 it is generally parallel to the first section 23 and parallel to the plane of the guide surface 14. The third section extends to the bottom or lower guide pulley 30 and is there deflected at about 180. This pulley is rotatably mounted in the bottom end portion of the second guide surface 14 of the vertical section 8 of the door frame 7.
From this pulley 30 the cable 22 extends in a fourth section or fourth component portion 26 up to the area of the second guide roller 12 and is attached to the axle 13 of the guiding rol~er 12, preferably by way of an end loop (see Fig. 3). In any case, the end 20 of the cable 22 and the other end of the same cable must be attached approximately at the same level of the door panel 11, preferably on the level of the axis of shaft 13 of the guiding roller 120 Fig. 3 shows that one end 19 of the second cable 21 extends downwards, i.e. in opposite direction of the cable 22, but parallel to the latter in a fourth direction 26 to a lower guide pulley 31; at this pulley it is deflected at a double-right-angle and in a third section _ extends to the one upper guide pulley 28, there deflected at approximately a right angle and extending, in a second section or second component portion 24, to the second upper guide pulley 29, then deflected by 90 downwards in the first section 21 to the second guiding roller 12 (the right hand rolLer 12 of Fig. 2), where it is likewise attached.
The axes 32 (Fig. 3) of all the pulleys 28-31 are parallel to each other and are perpendicular to the plane of the guiding surface 14. In this manner both cables 21, 22 may be moved without problems; both of the upper guide pulleys 28, 29 are designed as double-pulleys with a common shaft.
By this design and geometry, the guiding of the sections of each cable is secured so that the ends 19, 20 of the two cables 20, 21 are maintained on the straight line 33 (Figs. 3 and 4) so that each guiding roller 12 is subject to a forced guiding in such a manner that it runs continually in a parallel relationship with respect to the line 33 when the door panel is opened or closed. Twisting and jamming of the doors cannot occur or is at least very substantially limited.
It is typical for many doors of t'nis type that, on opening, the bottom edge of the door panel does not, in effect, swing from the plane defined by the closed door panel.

At the latter it is again deflected 90 so that in the third section or third component portion 25 it is generally parallel to the first section 23 and parallel to the plane of the guide surface 14. The third section extends to the bottom or lower guide pulley 30 and is there deflected at about 180. This pulley is rotatably mounted in the bottom end portion of the second guide surface 14 of the vertical section 8 of the door frame 7.
From this pulley 30 the cable 22 extends in a fourth section or fourth component portion 26 up to the area of the second guide roller 12 and is attached to the axle 13 of the guiding rol~er 12, preferably by way of an end loop (see Fig. 3).
