(10) FIG. 1 shows the schematic illustration of a segment 1 according to the invention, having strips 2 according to the invention, said strips 2 being disposed along a front end side 3 and a rear end side 4 of the segment. Ribs 6 which in the conveying direction 7 run so as to be mutually parallel are disposed on an upper side 5 of the segment 1 and the strips 2. In operation, the end sides 3, 4 face the neighboring segments, or the end sides of the neighboring segments, respectively (neighboring segments not illustrated).

(11) The strip 2 which, when viewed in the conveying direction 7, is disposed on the front has a convexly curved end side 3 which is directed away from the segment 1, and a concavely curved rear side 10 which is directed toward the segment 1. The strip 2 which, when viewed in the conveying direction 7, is disposed on the rear has a concavely curved end side 4 which is directed away from the segment 1, and a convexly curved rear side 10 which is directed toward the segment 1. The end sides 3, 4 of the strips terminate so as to be planar with the end sides 3, 4 of the segment.

(12) The ribs 6 of the strips 2 in terms of shape, alignment, and position, preferably match exactly the ribs 6 of the segment 1 such that each rib 6 runs so as to be substantially continuous and without a step or shoulder from the front end side 3 to the rear end side 4.

(13) A conveying installation which has a conveyor belt and which substantially consists of a line-up of successive segments 1, wherein the segments 1 are connected to one another and can pass curves having radii of dissimilar sizes is described and illustrated in WO 2012/097390 A1, for example. According to the invention, these segments are embodied as described in the present application.

(14) The segments 1 of the conveying installation can be connected to one another as described in Austrian patent application A 720/2015, for example, and the conveying installation, or the segments 1 of the conveying installation, respectively, can be driven as described in Austrian patent application A 396/2015, for example.

(15) FIG. 2 shows a detail of the front end side 3 from FIG. 1, having an end region 8 of the ribs 6 in the region of the front end side 3. The ribs 6, in a manner adjoining the end region 8, preferably but not mandatorily have a rectangular cross section 9.

(16) FIGS. 3 to 6 show in detail dissimilar embodiments of the end region 8 of a rib 6, wherein all ribs 6 are preferably but not mandatorily embodied in an identical manner.

(17) The illustrated rib 6 of the segment 1 according to the invention, or of the strip 2 according to the invention, has an upwardly directed cover face 11 on which people or goods to be transported can stand or lie, respectively, two lateral faces 12 that face the neighboring ribs 6, and optionally an end face 13 on the end side 3, 4.

(18) The rib 6 in the embodiment of FIGS. 3 to 6 furthermore has two lateral oblique faces 14, an upper oblique face 15 in FIGS. 5 and 6, and a front oblique face 16 in FIG. 6.

(19) The cover face 11 is disposed in an upper plane 17, and the lateral faces 12 are disposed in lateral planes 18. An end plane 19 is disposed on the end side 3, 4, said end plane 19 lying so as to be orthogonal to the upper plane 17 and, depending on the curvature of the end sides 3, 4, so as to be substantially orthogonal to the lateral planes 18. When an end face 13 is present, said end face 13 lies in the end plane 19. The rib 6 projects from a base plane 21 upward, wherein base faces 22 are disposed between the ribs 6 in the base plane 21.

(20) A lateral upper edge 23 is formed between the cover face 11 and the respective lateral face 12, and a lateral lower edge 24 is formed between the lateral face 12 and the base face 22.

(29) FIG. 4 shows another embodiment according to the invention of the end region 8 of a rib 6 having an end face 13 and a contact edge 27.

(30) The end face 13 and the cover face 11 taper up to the contact edge 27 which is disposed on the virtual end straight 35 so as to be centric between the lateral planes 18. The lateral oblique faces 14 abut the ends of the contact edge 27 by way of in each case one corner.

(31) Both the upper inclination angle as well as the lower inclination angle in this embodiment are approx. 135.

(32) FIG. 5 shows a further embodiment according to the invention of the end region 8 of a rib 6 having an end face 13, a contact point 26, and an upper oblique face 15.

The contact point 26 lies on the end plane 19, or the end face 13, respectively, so as to be centric between the lateral planes 18, and is spaced apart from the upper plane 17.

(35) In this embodiment, the upper inclination angle is approx. 150, and the lower inclination angle is approx. 120.

(36) FIG. 6 shows yet a further embodiment according to the invention of the end region 8 of a rib 6, having an upper oblique face 15, a front oblique face 16, and a contact edge 27 between said faces 15, 16.

(37) The virtual end plane 19 intersects the base plane 21 along a base straight 37, and the rib 6 in the end region 8 up to the end plane 19 becomes ever lower toward a front lower edge 38 which lies on the base straight 37.

(38) The upper oblique face 15 tapers from the rear upper edge 36 up to the contact edge 27 and is inclined from the upper plane 17 downward at an upper oblique angle . The front oblique face 16 tapers from the front lower edge 38 up to the contact edge 27 and is inclined away from the virtual end plane 19 at a lower oblique angle .

(39) The contact edge 27 lies so as to be centric between the lateral planes 18, is spaced apart from the upper plane 17 and from the end plane 19, and lies so as to be parallel with the virtual end straight 35.

(40) In this embodiment, the upper inclination angle is approx. 140, and the lower inclination angle is approx. 130.

(41) FIG. 7 shows portions of two mutually opposite strips 2 according to the invention of two neighboring segments 1. The illustrated design embodiment of the end region 8 of the ribs 6 corresponds to the particularly preferred embodiment illustrated in detail in FIG. 3.

(42) The front end side 3 of the strip 2 depicted on the left in FIG. 7 is convexly curved, and the rear end side 4 of the strip 2 depicted on the right in FIG. 7 is concavely curved in a manner corresponding to the former.

(43) In one particularly preferred embodiment of the invention, each rib 6 has a half width B of, for example, 4 mm, this corresponding to half the distance between the two lateral planes 18 of a rib 6 and being pre-defined by already existing statutory specifications, for example.

(44) A height Z of the lateral front edges 25 is preferably smaller than 2 mm, and an end height H which corresponds to the rib height minus the height Z is preferably smaller than 1.5 times the half width B, thus preferably smaller than 5 mm, for example.

(45) For production-related reasons, or by virtue of mechanical play in the connection of the neighboring segments, there is gap having a gap width D between the end sides 3, 4 of neighboring strips 2 or segments 1, respectively. The gap width D is preferably as minor as possible, for example 2 mm.

(46) A length L of the end region 8 and thus also of the lateral oblique faces 14 is preferably 2.5 to 5 times the length of the half width B, for example 11 to 16 mm.

(47) FIG. 8 shows three further embodiments according to the invention of the end region 8 of a rib 6.

(48) The embodiment illustrated in the center of FIG. 8 has two lateral oblique faces 14 which are inclined away from the respective lateral plane 18 in the direction of the other lateral plane 18 of the same rib 6, but not inclined away from the end side 3, 4 in the direction of the rib 6.

(49) The embodiments illustrated on the right and the left in FIG. 8 have curved oblique faces 14, 15 and end faces 13 in the form of circle segments.

(50) Since the curved oblique faces 14, 15 can also be considered to be a number of lateral and upper oblique faces 14, 15 which are disposed beside one another and embodied so as to be narrow, these embodiments likewise represent a bevel of the end region 8 of a rib 6 in the context of the invention.
