Definitions

  • the invention relates to a time switch in which a rotary knob driven by a small electric motor via a reduction gear is set up for manual setting to the correct time and contains a ring of dimensionally identical programming elements which can be moved to two alternative latching positions at their outer end and with their inner end Depending on the latching position, are located inside or outside the detection range of a swivel-mounted scanning lever, and between the spring-loaded nipple of a microswitch suitable for mains current and the scanning lever, a changeover mechanism for the three timer states, program operation or permanent on or permanent off, is inserted, via a on the front of the Timer housing arranged actuator is accessible.
  • timers are used for time-dependent switching the power supply of mains-operated electrical devices.
  • different time switch housings can be provided with an otherwise uniform design.
  • the external appearance of the time switch is mainly characterized by a terminal strip in the variant intended for installation in a power distributor, in the variant intended for installation in a flush-mounted box by a cover surface, in the variant which can be plugged into a mains socket by a further socket and in which Device installation certain variant due to the smallness of the time switch housing itself.
  • space heating can be switched from program operation to the permanently on state or the permanently off state without the switching cycle programmed into the time switch being deleted.
  • the rotary knob of the time switch can be provided with a round scale for a weekly program or a daily program or a short-term program with appropriate adaptation of the reduction gear.
  • a time switch of the type mentioned at the beginning is already known from the market due to its own manufacture.
  • the changeover mechanism of this time switch requires a separate housing opening for the actuating member of the changeover mechanism arranged on the front of the time switch housing, which increases the lateral space requirement of the time switch and accordingly limits the installation options of the time switch.
  • On the pivotally mounted scanning lever an angularly deflecting lever with a lever arm is loosely supported in the middle region, whereas the other lever arm of the deflecting lever is set up to depress the resilient nipple of the microswitch.
  • the nipple is pressed down by the Preload of a spring acting on the bell crank as long as the cam curve formed by the programming elements offers the scanning lever an immersion possibility.
  • the nipple can be continuously depressed by a slide which can be engaged between the force of the additional spring and the deflection lever.
  • the opposite permanent timer state is achieved when the slide holds the bellcrank in an intermediate position close to the nipple.
  • the bellcrank has a run-up slope opposite the slide and the slide has a run-up slope opposite the nipple.
  • the actuating member of the changeover mechanism arranged on the front of the time switch housing is connected to the slide, which is longitudinally guided on the narrow side of the cuboid-shaped encapsulated microswitch, by a plug-in coupling and, in turn, has a slide-shaped design.
  • the associated broad-sided alignment of the microswitch to the front of the time switch housing wastes space in the radial direction of the rotary knob.
  • a disadvantage of keeping the front of the time switch housing small and keeping the production costs of the time switch small is, in particular, the large number of components required for the changeover mechanism.
  • the invention has for its object to reduce the manufacturing costs for a time switch of the type mentioned with the aid of a simplified switch mechanism for the three time switch states program operation or permanent on or permanent off on the one hand and on the other hand via a Lateral reduction of the time switch housing to create more installation options.
  • the sliding body is assigned to the other end of the angular groove of the sliding body resting next to the nipple and the central region of the angular groove of the sliding body allowing the scanning movement of the scanning lever on the nipple.
  • the slotted disc forms a physical unit that can be produced cost-effectively with the actuating element of the switching mechanism.
  • the sliding body which is mounted on the scanning lever so as to be longitudinally displaceable, represents a structural design of the scanning lever.
  • the cuboid-encapsulated microswitch can now be aligned towards the front of the time switch housing, which includes an additional gain in space in the radial direction towards the rotary knob and serves to change the direction towards the rear Makes soldering tag attachments of the microswitch unnecessary.
  • a switching tongue protruding from the link plate as the actuating member is close to in a circular cylindrical shape from the time switch housing led out through a local extension of the opening in the timer housing for the rotary knob. This ultimately leads to the fact that the time switch housing partially extends beyond the rim of the programming elements in the radial direction only in a width sufficient for fastening holes.
  • the time switch shown in the drawing has a time switch housing 12 which is divided into a somewhat lower front part 10 and a less deep rear part 11.
  • the connecting screws provided for holding the time switch housing 12 together are omitted in the drawing for the sake of clarity, as is the one between the small electric motor 13 and the reduction gear having an internal toothing knob 14 required.
  • Most of the small electric motor 13 is accommodated in the rear part 11 of the time switch housing 12.
  • the cuboid-encapsulated microswitch 15 extends with one end face up to the rear wall 16 of the time switch housing 12.
  • the two solder lugs 17 and 18 of the microswitch 15 are passed vertically through this rear wall 16.
  • the programming elements 19, which are displaceable at their outer end with a fingernail or a fine pen in two alternative locking positions and are located with their inner end depending on the locking position inside or outside the detection range of the pivotably mounted scanning lever 20, together form the front edge of the rotary knob 14 and are assigned to the individual markings of a self-contained time scale 21 of the rotary knob 14.
  • a scanning lug 28 protrudes from the scanning lever 20 in one pivoting direction thereof and a switching lug 30 provided with a ramp 29 in the opposite pivoting direction.
  • An additional saving of space results from the fact that at the free end of the scanning lever 20 there is a taper 31 with a rectangular cross-section extending up to the scanning nose 28 for the longitudinally displaceable mounting of the sliding body 22.
  • the switching lug 30 rests against it Next the then sprung-out nipple 32.
  • the shape and position of the angular groove 25 are also selected so that the scanning movement of the scanning lug 28 is transmitted via the switching lug 30 to the nipple 32 of the microswitch 15 in the central position of the link plate 27.
  • An additional advance in the increase in the installation options of the time switch by a lateral reduction of the time switch housing 12 means the fact that a switching tongue rising from the link plate 27 as the actuating member 26 is located close to the rotary knob 14, which is guided in a circular cylindrical shape out of the time switch housing 12, by a local expansion 33 in the time switch housing 12 for the knob 14 opening 34 runs.
  • the second housing opening that is otherwise required on the front side 35 of the time switch housing 12 has been eliminated.
  • the actuating element 26 of the switchover mechanism has been considerably simplified, especially since it ends in the form of a switchover tongue in front of the outer end of the inwardly latched programming elements 19 in a radial bend 36.
  • the switching tongue 26 forms with the link plate 27 a physical unit that is easy to manufacture by punching and bending, is relatively inconspicuous due to its flat lateral approach to the rotary knob 14 and nevertheless allows convenient and safe operation with the fingertip at its radial angle 36. Since the link plate 27 can be pivoted about the rotary knob axis 23, it does not require a separate bearing. In its radial extent, the link plate 27 remains below that of the rotary knob 14. A part of its circumference acts through a curved incision 37 as a locking element 38, to which three alternative locking recesses 39 are assigned on the inside of the timer housing 12.
  • the time switch housing 12 projects only partially over the rim of the programming elements 19 in the radial direction to an extent sufficient for fastening holes 40. This opens up further possibilities for individual installation for the time switch and, on the other hand, also achieves improvements in terms of space-saving group installation.
