Definitions

  • the invention relates to a program carrier for switching timepieces with a motor-driven drum, which has a plurality of switching elements which can be adjusted between an effective and an ineffective position, and which cooperate in their effective position with a scanner for controlling a switch.
  • an electrical switch of the type mentioned above (DE-PS 28 13 069) consists of the program carrier in at least two mutually mounted and fixed parts, a motor-driven drum and fitted onto the drum a and in engagement with standing, switching disc.
  • the jacket of the drum is provided with guide slots which are open on one side and extend in the direction of the drum axis and into which radially extending, movable arms of switching elements extend. These switching elements are connected there via the movable arms to form a one-piece switching disk.
  • This device is associated with the considerable disadvantage that, in particular, the manufacturing tolerances of the individual movable arms and the switching elements arranged there and engaging with the casing of the drum must be extremely precise with respect to the outer diameter of the casing of the drum in order to achieve the desired effect there. ensure the two secured switching positions of the individual switching elements on the jacket of the drum.
  • the invention has for its object to provide a program carrier of the type mentioned which does not have these disadvantages and which can be produced, assembled and assembled simply, efficiently and economically and whose switching elements not only work independently of one another but also enable reproducibly secured switching positions.
  • the program carrier according to the invention is made of a plastic.
  • Fig. 1 shows a program carrier from a one-piece plastic part, which consists essentially of a drum 1 with a bottom 2 and a jacket 3, where there, at the free end of the jacket 3, in particular at right angles to the jacket 3, radially outwards extending movable arms 4 are arranged, which are integrally connected via a hinge 5 to the jacket 3 and thus the drum 1.
  • the arms 4 are provided at their free end with switching elements 6, i.e. the movable arms 4 can act directly as switching elements 6.
  • the arms are 4 Functional by 90 0 , pivotable upwards in the direction of arrow 7.
  • 8 shows locking pawls on each arm 4 or switching element 6.
  • These locking pawls 8 are provided with a locking lug 9 as well as with a locking cam 10 for the functionally appropriate engagement with corresponding counter-locking elements 11, which are arranged in the area of the base 2, such as the following figures show in more detail.
  • FIG. 2 shows a sectional view of the special design of the injection molded part, in particular in the area of the joints 5 and in the area of the latches 8 and the corresponding counter-latching elements 11.
  • the present example of the injection molded part shows the relatively simple tool manufacture of such a program carrier.
  • the cohesive connection of the arms 4 / switching elements 6 with the jacket 3 of the drum 1 in the area of the joints 5 ensures a connection which has been tried and tested in plastics technology, especially since this joint 5 is not subjected to any significant load in the function of the arms 4 engaging in function.
  • Fig. 3 shows the functionally assembled program carrier by there the movable arms 4 with the switching elements 6 were manually or mechanically pivoted upwards such that the latches 8, in particular the locking lug 9 on each arm 4 behind the latching edge 14 in the area of upper jacket sector snaps.
  • the jacket 3 is provided with openings for the entry of the latches 8 there.
  • annular locking grooves 15 are provided, into which the locking cams 10 of the arms 4 can be locked in accordance with the program.
  • the locking grooves 15, together with the locking cams 10 ensure the two possible, radially different switching positions of the arms 4 and thus the switching elements 6.
  • the switching elements 6 can be scanned on the outer circumference, as one of the following figures shows. However, it is also provided that the scanning of the respective switching position of a switching element 6 can also take place directly on the latches 8, in the interior of the switch 1, as the switch 16 arranged there shows with a scanner 17.
  • FIG. 4 clearly shows the possible programmability of the switching elements 6, which can be pivoted out or in individually there, or that a so-called switching path can be formed from a plurality of switching elements 6 pivoted out or in.
  • a switching path 18 can be scanned by an external scanner or a scanner 17 arranged in the interior of the drum 1, for controlling a switch, in particular an electrical switch, which is not shown in detail.
  • 19 means an adjustment scale on the upper side of the bottom 2 of the drum 1.
  • Such a program carrier due to its closely spaced, spatially relatively narrow switching elements 6, enables a high resolution of a switching program with relatively small switching time intervals of two switching elements programmed with different switching programs 6.
  • Such a program carrier can be inserted in a timer. 20 shows such a housing in a top view.
  • the program carrier described above is mounted horizontally, as is often required in so-called distributor time switches. There, the programmed switching elements 6 can again be scanned inside the drum 1. This ensures that with a certain viewing position, in particular on a setting scale 19, the scanning can be placed immediately behind it, so that it is not necessary to provide a special setting scale and a reading scale, as required by the execution of the known time switch described at the outset.
  • annular adjusting scale part 21 which in particular has a U-shaped cross section, and which, from the open side of the drum 1, on the inner circumference of the jacket 3 adjacent, assembled ie is pushed onto the drum.
  • An adjustment scale can be arranged on the outer lateral surface 22 of the part 21.
  • the present program support can also have a different design. Especially the length the arms 4 or the switching elements 6 can be relatively short, so that ultimately in the broadest sense there is no longer a drum, but only a disk as a carrier of the switching elements 6.
  • the effective or ineffective position mentioned at the outset should be understood here to mean that in one position of a switching element a certain effect caused by the scanner occurs, while this does not occur in the other position of the switching element; However, this does not exclude that a different effect occurs in the inactive position, as is the case, for example, when controlling an electrical changeover switch.
  • such a program carrier according to the invention instead of plastic, can also be punched and drawn from a metal sheet with the same manufacturing and assembly technology advantages.
  • the economy of the present program carrier is obvious compared to the statements of the prior art.
  • the program carrier according to the invention can be used in the known switching timepieces without restriction.
