DESCRIPTION OF THE PREFERRED EMBODIMENT
Shown in F.ig. 1 i.s a guide bar 1 utilized in the aligning of sliding elevator doors. The guide bar 1 includes an elongated, generally L-shaped cross section beam 2 attached to a guiding means in the form of a sliding guide 3, the beam 2 and the sliding guide 3 each extending longitudinally :in the direction of travel of an elevator 2~3~~~
door. The beam 2 can be manufactured from a commercial cold-rolled quality steel and formed with a first generally horizonta'l1y extending web 4 attached to a second generally vertically extending web 5 in a right-angled configuration.
The surfaces of the beam 2 can be protected against corrosion by means of a cadmium layer or coating. For the attachment of the beam 2 to an elevator door (not shown), a plurality of fastener receiving mounting apertures 6 are formed in the second web 5. Two groups of attachment apertures 7 are formed in the first web 4 to accept suitable fastening means such as bolts 8 and nuts 9, which fastening means connect the sliding guide 3 with the first web 4. The sliding guide can be molded of a durable nylon material and extends downwardly into a groove (not shown) mortised into the elevator door sill, whereby the elevator door is guided in a predetermined sliding track defined by the groove. In an alternate embodiment, roller guiding means (not shown) could I be provided in place of the sliding guide 3.
In the embodiment shown in Fig. 1, six apertures 7 are provided in each of the two groups on the first web ~ for the accommodation of any structural deviations in the elevator door structure. Each opening 7 is formed from three intersecting circular recesses 10 as shown in Figs.
2 through 5. The fastening means axe inserted, depending on the necessary correction for any structural deviation, into the corresponding opening 7 and one of the associated recesses 10. Center points A, B and C of the three circular recesses 10 define the intersections of the three sides of an - isosceles triangle, wherein a straight dashed line drawn fram ,, the point C is perpendicular to a straight dashed line drawn between the points A and B. The distance between the pois~t C
and the straight line between the points A and point B is one half of the distance between the points A and B as shown in Fig. 2. This relationship assures that a head 8.1 of the bolt 8 is supported on at least two thirds of its circumference by the first web 4 as shown in Figs. 3 and b.

The surfaces of the beam 2 can be protected against corrosion by means of a cadmium layer or coating. For the attachment of the beam 2 to an elevator door (not shown), a plurality of fastener receiving mounting apertures 6 are formed in the second web 5. Two groups of attachment apertures 7 are formed in the first web 4 to accept suitable fastening means such as bolts 8 and nuts 9, which fastening means connect the sliding guide 3 with the first web 4. The sliding guide can be molded of a durable nylon material and extends downwardly into a groove (not shown) mortised into the elevator door sill, whereby the elevator door is guided in a predetermined sliding track defined by the groove. In an alternate embodiment, roller guiding means (not shown) could I be provided in place of the sliding guide 3.
In the embodiment shown in Fig. 1, six apertures 7 are provided in each of the two groups on the first web ~ for the accommodation of any structural deviations in the elevator door structure. Each opening 7 is formed from three intersecting circular recesses 10 as shown in Figs.
2 through 5. The fastening means axe inserted, depending on the necessary correction for any structural deviation, into the corresponding opening 7 and one of the associated recesses 10. Center points A, B and C of the three circular recesses 10 define the intersections of the three sides of an - isosceles triangle, wherein a straight dashed line drawn fram ,, the point C is perpendicular to a straight dashed line drawn between the points A and B. The distance between the pois~t C
and the straight line between the points A and point B is one half of the distance between the points A and B as shown in Fig. 2. This relationship assures that a head 8.1 of the bolt 8 is supported on at least two thirds of its circumference by the first web 4 as shown in Figs. 3 and b.
~~~~~~
Designated with D in Fig. 5 is the smallest step width possible for accommodating a deviation in a direction transvexse to the sliding axis of the first web ~., The step width D corresponds to one quarter of the distance between the points A and g. The openings 7, as shown in Fig. 5, are arranged in a pattern such that the central points A, B and C
of the recesses 10 are displaced alternatingly by the step width D whereby eighteen possible points of attachment are - provided in comparison to the possibility of six points of attachment provided by six conventional circular apertures.
Teeth 11 are formed on each end of the first web 4.
Depending on the attached position of the sliding guide 3 on I
the beam 2, one of the teeth 11 is selected and bent downwardly to extend into but not touch the walls of the i 15 guiding groove (not shown) for the sliding guide 3. For example, in case the sliding guide 3 is destroyed by fire, the elevator door can be kept blocked since the bent teeth 11 will engage the groove.
In summary, a guide bar for an elevator door includes a beam adapted to be attached to an elevator sliding door, a guiding means for engaging a groove and fastener means for attaching the guiding means to the beam. The beam has a generally horizontally extending web and a plurality of attachment apertures formed in the web, the attachment apertures being arranged in a staggered pattern providing at least as many possible points of attachment of the guiding means to the beam as the number of attachment apertures. The attachment apertures are each formed from three generally circular recesses having center points defining the intersections of the sides of an isosceles triangle and one of the center points being located along a straight line extending perpendicular to a straight line between the other two center points a distance one half of the distance between the other two center points.
In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced S otherwise than as specifically illustrated and described without departing from its spirit or scope.
