distancing or spacing elements 8 are seated between the adjacent latching elements the height of these distancing elements 8 which extend between the inside base surface 200a of the part 2a and the glide plate 9 should be slightly greater than the height of the latching element comprising carrier 3 and rider 4 as can be seen in fig1 b the glide plate 9 and the distancing elements 8 can also be configured as a one piece component as shown in fig2 d fig3 and 4 show embodiments of the second variation of the invention which relate to an emergency or panic locking system and can readily be combined with the above described first invention variation correspondingly the riders 4 39 have extensions 4a which extend in the direction of the side b where an opening closing bar 90 integrated into the locking system is disposed the carrier 3 39 and the rider 4 39 are again in form fitting engagement with each other by way of their toothing 30 40 as long as the relative position of the two parts 3 4 was not locked they can be displaced toward each other in order to transfer the code of the key to the locking core in the process the latching recess 41 of one of each of the riders 4 assumes its specific position so that when a key that fits is inserted the latching recesses 41 of all of the riders 4 of the locking core create an alignment into which the latch of a latching element can drop the rider 4 39 shown in fig3 has an inside recess 430 for seating a stop element that.
