Definitions

  • a timer of the type mentioned which has a one-piece switching disk with two guide disks, which are firmly connected to each other via a hub.
  • This time switch proves disadvantageous in that the two guide disks cannot be fixed in any position relative to one another, so that an adjustment in the direction of rotation is necessary. This complicates automated manufacturing.
  • the present invention is based on the problem of creating a program carrier for an electrical time switch, in which an adjustment in the direction of rotation is not necessary and which enables automated production.
  • Fig.1 is shown on an enlarged scale, as the switching elements - from the base - as a rod-shaped flat edge piece 1 with a leg in the thickness given by the division of the selectable time steps 2 with an L-neck 3 in its plane and each a cantilever 4 parallel to the flat edge piece 1 as a second leg of reduced thickness 5 is constructed flush with an outer wall of the flat edge piece and are united by means of an arcuate connecting piece 6 to form a U-shaped switching element 7.
  • the switching elements 7 can be displaced in one of their selectable positions in the longitudinal direction of their legs in the program carrier, as explained in more detail below, adapting to the particular characteristics of the variant in question according to the construction principle common to them.
  • Fig.1 are a side view of a normal version (a), a first alternative thereof (a ') and a second alternative (a ⁇ ), in the front view, on the one hand (b) in section AA (see a) and uncut (b ⁇ ), in the bottom view on the cam 12 with certain differences in (c 'and c) or (c ⁇ ) and finally in the top view of the L-neck 3 in (d ⁇ in section and d) in normal - And alternative execution shown.
  • the L-neck 3 is used in all versions as an actuating means of the switching element 7 and as a stop for limiting the displacement path in the outward direction.
  • the flat edge piece 1 has on the outside (top view) a longitudinal groove 8 with widening 9 at the connector-side end, also there in connection with special features of the respective alternative details, a taper 10, and a taper 11 of the connector 6, all for better insertion of the switching element in the associated groove of the ring body (21 in Fig. 3 and 73 in Fig.7).
  • the boom 4 has at its free end or between the L-neck 3 and the curve for the connector 6 a cam 12 with two opposite on the outside of the boom 4 there Inclination sections 13, 14 for latching the switching element 7 by snap action of an associated counter-cam ring (44 in Fig. 6 or 65 in Fig. 8) in the adapter ( 41 in Fig. 6 or 62 in Fig. 8).
  • the normal version (a) of the switching element 7 is in an alternative 7 '(a') with a nozzle 15 in the extension of the boom 4 beyond the cam 12 or in another alternative 7 ⁇ (a ⁇ ) with an extension 16 of the connecting piece 6 executed.
  • the individual views, the side view a), the front view b), the bottom view c) and the top view d) are in all cases, ie. the axial displacement in Fig.2a and 2b, or for radial displacement in Fig.2c and 2d with mutually matching letters.
  • some switching elements are shown in plan view d) as they are packed together in the grooves of the annular profile carrier 40 to be described later (when compared at right angles to the plane of the drawing of Figure 5a) or in the case of radial displacement of Fig.2c (b) inserted the corresponding arrangement in the grooves 73 of the annular profile carrier.
  • FIG. 1 As has already been done in part, other corresponding reference numerals from FIG. 1 can also be adopted analogously to FIG. 2.
  • mirror-image switching element halves are intended for combination in pairs in a common groove (22 in FIG. 3a or 73 in FIG. 7a), so that for the same number of switching elements only half the number of grooves 8 for guidance in the associated groove ring of the ring body 21 is required.
  • the longitudinal grooves 8 in the offset outer surface (outer surface) 17 (top view) of the flat edge piece 1 for the longitudinal grooves 8 in the offset outer surface (outer surface) 17 (top view) of the flat edge piece 1, however, the full number of assigned webs 31 in a concentric section of the program carrier is required.
  • FIG. 1 can easily be transferred from the examples there to the examples of FIG. 2 that are specially designed in detail.
  • the different peculiarities of the cases of these detailed examples in FIGS. 2a to d, as can be readily recognized, can be adapted in other respects without influencing the actual essence of the inventive features.
  • FIG. 3 shows, as such, the lower part 20 of the program carrier in a first variant for the axial displacement direction of the switching elements a) in the front view and b) in section.
  • the structure of the annular body 21 serving as the lower part 20 with the annular groove 22 can be seen. It is a pair of two cylinder connectors 23, 24 and a disk ring 25 as a connecting element with a molded ring of equidistant webs 30 on the outer wall 27 of the inner cylinder connector 24 and a likewise integrally molded ring of small bars 31 on the inside 29 of the outer cylinder connector 23 composed.
  • the switching elements 7 are inserted with their flat edge pieces 1 in a snug sliding fit, the longitudinal grooves 8 of which on the outer surface 16 of the flat edge piece 1 also receive the small webs 31 on the inside 29 of the outer cylinder connection piece 23 in a sliding manner.
  • the arrangement of the webs 30 as a ring on the outside 27 of the cylinder neck 24 on the one hand and the small bars 31 as a ring on the inside 29 of the outer cylinder neck 23 on the other hand are shown in their circular distribution on the circumference in FIG. 3a of the circular surface.
  • the lower part 20 of the program carrier thus has for the switching elements 7 the receiving function of an annular bed, in which the switching elements are grouped as a closed form and arranged into a ring - can be effortlessly inserted into the annular groove 22 from one side (from above onto the plane of the drawing) .
  • the directions of displacement of the switching elements 7 are indicated by the arrow 32.
  • the lower part 20 is drawn in with a toothed ring 33 for driving the program carrier about a shaft (not shown) with the axis 34.
  • a drive also not shown, with a conventional gear, this can be accommodated in the central recess 35.
  • FIG. 4 shows in front a) and top view c) and in section b) as another section the upper part 39 of the program carrier, which as a fitting 41 with a concentric tube wall 42 with an axial outer profile compatible with the ring body 21 of FIG Fastening elements distributed over the circumference with snap lug 43 are clamped to the lower part (FIG. 3) and thus secure the switching elements 7 in the annular groove 22 after being fitted against falling out.
  • One of the snap elements 43 can be seen in section and in the front view.
  • the tube wall is equipped with an integrally formed flange 45 and has a cam ring 44 which, with a counterpart (each switching element) as a locking means known per se, is shifted in the axial direction (parallel to the longitudinal direction of the flat edge piece 1 in FIG. 1) by snapping one of the two inclination surfaces of the cam ring 44 cooperates in the sense of locking one of the two displacement positions.
  • the adapter 41 is inserted into the interior of the annular body 21 serving as the lower part 20, the annular groove 22 is covered by the flange 45 after it has been completely equipped with the ring of switching elements 7 and the switching elements 7 are secured against falling out, but the L-lugs 3 remain accessible and visible for adjusting the switching element 7.
  • FIG. 2a a left (FIG. 2a) and a right switching element 7 (FIG. 2a) are alternately accommodated in grooves 22 between the two webs 30; the webs 30 serve as a sliding guide for the switching elements.
  • the flat edge pieces 1 slide mutually and take up the small webs 31 in their longitudinal groove 8.
  • the outside of the L-lugs 3 of the switching elements 7 form a cylinder jacket. The direction of displacement has to be imagined at right angles on the drawing plane.
  • FIG. 5b shows this exemplary embodiment with the parts of the program carrier with the annular body 21 of FIG. 3 serving as lower part 20 and the fitting piece 41 (FIG. 4), equipped with (all) - left and right - switching elements 7 corresponding to the number the selectable time levels, partially inserted, e.g. 46, or pulled out, e.g. 47, which can be seen from the position of the L-neck 3.
  • the inserted switching elements 47 give a clear view of the outer tube flange 45 of the fitting 41 serving as the upper part 39 of the program carrier.
  • the gear rim 33 for the drive and the remaining outer surface 49 of the outer cylinder socket 23 of the program carrier are visible on the opposite edge surface in the operational program carrier of this exemplary embodiment.
  • This peripheral surface is expediently usable for the application of a time scale. Outside of this time scale (housing part 37 indicated broken), one has to imagine a fixed marking arrow 38 at a suitable point.
  • FIG. 7a shows a second variant of the program carrier with radial shifting of the switching elements.
  • the structural principle is basically the same as that of FIG. 5 with an axial displacement of the switching elements and corresponds to that of the ring body of FIG. 3 serving as lower part 20, which has the function of a bed for the switching elements in a formally closed grouping and order to form a combined ring and the fitting 41 of Fig.4.
  • cam ring 65 in the form of a disk with rising and falling inclination surfaces 66, 67, with which the cam 12 of the switching elements 63, which are otherwise appropriately designed, cooperates - in accordance with the basic principle of FIG. 1.
  • the direction of displacement of the switching elements is indicated by arrow 64.
  • the principle of the adapter 62 and its shape also agree Except geometrical details (see Fig. 4) match those.
  • FIG. 7b The phantom-like drawing of FIG. 7b, where the underside of the counter profiles of the ring body 61 are arranged vis-à-vis the underside profile of the cam ring 65 (or 12) for the arm 4 of the switching elements, also makes it easier to read these special features in connection with the ring body 61, the radial grooves 72 and the radial webs 73.
  • Switching elements 63 are also visible in weak lines - in pairs and after removal of the fitting 62 used as the upper part 48. Switching elements are inserted 74 or pulled out 75 in the layers in FIG .
