Abstract

TOOTHED ANCHORING RAIL

ABSTRACT
The present invention relates to an anchoring rail consisting of a hollow section with a slot running in longitudinal direction and with each of the sides of said slot being provided with a row of holes. The holes on the anchoring rail are engaged by corresponding rail provided on a latching plate that is wider than slot and is part of a mounting element.

Description

The present invention relates to an anchoring rail for use with a mounting element.
Commercially available anchoring rails are known that consist of a hollow section of rectangular cross section and are provided with a longitudinal slot for inserting mounting elements.
The free ends of the arms forming the slot are bent inward into the hollow section and are parallel to each other. These ends face the bottom of the hollow section and their edges are provided with toothing open towards the bottom of the hollow section. The mounting element, being a bolt, is provided with corresponding toothing on its face facing the threaded shaft. The hammer head of the bolt is inserted through the slot into the hollow section, rotated by 90 into a position in which the teeth can engage, and tightened by means of a nut. The toothing provided on the hammer head engages the corresponding toothing at the ends of the arms bounding the slot, and the teeth are pressed together as the nut is tightened.
The load carrying flanks of the teeth are in contact with each other in longitudinal direction of the anchoring rail and lie in a plane that intersects at an acute angle the plane of the slot, with the result that forces acting on the bolt in longitudinal direction of the anchoring rail produce stresses in the screwed connection that act in axial direction of the bolt.
It has been found the such anchoring rails with mounting elements latched in this manner are capable of taking up large loads acting transversely or vertically on the anchoring rail, but that heavy loads in the longitudinal direction of the anchoring rail may .. , ~L

. .

cause the mounting element to slide in longitudinal direction of the slot. Accordingly, loads acting in longitudinal direction of the anchoring rail that can be taken up are smaller than loads acting transversely or vertically on the anchoring rail.
The object of the present invention is to provide a suitable design of the anchoring rail and mounting element such that essentially equal loads acting transversely, vertically, or longitudinally on the anchoring rail can be taken up without dislocating the mounting element.
The invention provides an anchoring rail for use with a mounting element and having a substantially rectangular hollow shape in cross section at right angles to a longitudinal axis of the anchoring rail and one side of the anchoring rail having arm edges defining a longitudinal slot of which a width is smaller than the width of the hollow shape cross section;
a fastening element inserted in an interior of the hollow anchoring rail and being shiftable in a longitudinal direction of the anchoring rail;
said fastening element including a threaded bolt having a widened head portion of which the width is greater than the width of the longitudinal slot;
a latching plate arranged and associated with the fastening element;
said latching plate having a width which is equally as large as the width of said longitudinal slot and on a side of said widened head toward a threaded shaft of said fastening element at oppositely located narrow sides of said widened head respectively lZ93713 said widened head portion having engagement surfaces in the form of recessed shoulders offset in level as to said latching plate and on opposite sides of said latching plate which engagement surfaces lie deeper than said latching plate;
said engagement surfaces being located in the same plane and lying in an engagement position of the fastening element on an inner surface of said anchoring rail arm edges;
said engagement surfaces having multiple pins arranged at right angles to each engagement surface and projecting in a same direction as said threaded shaft and located in the longitudinal direction of the anchoring rail and arranged respectively in two rows located opposite to each other;
a row of holes closed in a peripheral/circumferential direction in both said arm edges of said anchoring rail and in longitudinal spacing similar to that of said pins, each of said holes having axes at right angles to the arm edges;
said pins engaging positively in the holes in the engagement posltion of said fastening element; and said latching plate being located in said latter position in the longitudinal slot in such a manner that said latching plate bridges spacing between said arm edges of said anchoring rail.
Other characteristics of the present invention will appear from the claims, the explanation, and the drawings that show by way of example an embodiment of the present invention.
Fig.l: Shows a perspective view of an embodiment of an anchoring rail according to the present invention; and lZ93713 Fig.2: Is a perspective view of a bolt associated with the anchoring rall shown in Fig. 1.
Fig.1. is a perspective view of the anchoring rail 1 formed by the steel hollow section 2 of approximately rectangular cross section. A slot 3 running in the longitudinal direction of anchoring rail 1 is provided in one of the wider sides S, with the width B of said slot being smaller than the width of side S. Two arms 13,14 remain at both sides of slot 3 in the plane x,y of the side of the hollow section or in the plane 12 of slot 3 respectively.
Teeth in the form of holes 17 are machined in both arms 13,14, for example by pressing-in or by punching. The holes 17 are uniformly spaced in the longitudinal direction of the anchoring rail 1. The holes 17 in one arm are symmetrical to those in the other arm 27, with respect to the longitudinal centre line of slot 3. Holes 17 in the arms 13,14 are approximately oval in plan view, with their longer axes 33 (greatest width) oriented transversely with respect to the anchoring rail 1 and their bore axes 18 vertical to the plane of slot 3 defined by the two arms 13 and 14.
Fig.2 shows the mounting element to be inserted in anchoring rail 1: it consists of a threaded bolt 9 with a latching plate 8 integrated in its head. The hammer head 20 of the bolt 9 has an approximately rectangular shape with rounded narrow sides 29,30, with the length L of the narrow sides being smaller than width B of slot 3. The wide sides 31 of the hammer head 20 are longer than the width B of slot 3, but somewhat shorter than the ,,~

internal width C of the hollow section 2 forming the anchoring rail 1.
The latching plate 8 is machined in the bottom 22 of the hammerhead that faces the threaded shaft 21. A shoulder 32 is open towards each narrow side. Each shoulder 32 is provided with pins 19 whose axes are oriented parallel to the longitudinal centre line 35 of threaded bolt 9. The pins are preferably provided with tapered tips, and have a circular cross section whose external diameter is equal to or smaller than the smallest width of the oval-shaped holes 17 in the anchoring rail 1. The distance between the pins 19 measured in direction of the wider side of the hammerhead 20 corresponds to the distance between the holes 17 of the anchoring rail 1 measured in transverse direction of the anchoring rail 1.
This adaptation of the threaded bolt 9 to the dimensions of the anchoring rail 1 makes it possible to insert hammerhead 20 by its narrow side through slot 3 into the hollow section 2. When the bolt 9 is rotated by 90 its hammerhead 20 is positioned underneath arms 13 and 14. In this position the pins 19 in the hammerhead face the holes 17 in the anchoring rail, and interengage when bolt 9 is moved axially out of anchoring rail 1.
After insertion of the threaded bolt 9 in the manner described above, pins 19 sit with form-fit in holes 17 and hold bolt 9 which is secured in the engaged posi~ion by a nut or the like. The load carrying flanks of the teeth are vertical to plane 12 of slot 3, which ensures support of the threaded bolt 9 free from any axial forces that may loosen the screwed connection.

Also, latch plate 8 closes slot 3 in the transverse direction of anchoring rail 1, which ensures that equal loads can be taken up in all directions.
Accordingly forces acting on bolt 9 in longitudinal direction of the anchoring rall 1 are directly transferred to the anchoring rail 1 by the engaged pins 19 and holes 17 without applying any load to the screwed connection between bolt 9 and anchoring rail 1 that would tend to loosen the screwed connection.
Forces acting on the bolt 9 in transverse direction or vertical direction of the anchoring rail are directly transferred to the anchoring rail itself. The fact that, in the embodiment shown by way of example, the latched-in threaded bolt forms a common plane with the arms of the anchoring rail contributes to the high load carrying capacity in all directions. Accordingly the latching plate 8 lies fully within slot 3 and fills it is such a manner that, with the head of the bolt or a similar mounting element inserted, the longer side S of the anchoring rail is closed by a plane surface.
