Description

15 20 25 30 CO U! 40 512 687 2 days and each rider has position-holding latches for two positions.

When reprogramming, several control riders must be moved or switched to their second locking position, which is time consuming and cumbersome, especially if the program varies from day to day but is repeated week by week. If fl the movement or adjustment of the maneuvering riders and the adjustment of the slides is not only time consuming, but must also be done with care and accuracy to prevent incorrect programming.

The purpose of the invention is fulfilled with the invention specified in claim 1. Preferred embodiments are set out in the dependent claims. According to the invention, at least one connecting element and a disconnecting element, which form a pair of operating elements, are fixedly connected to each other by means of a common operating element carrier with an angular distance corresponding to a certain switching time, each operating element pair being able to be attached or attached to the program carrier. as a unit according to the desired program and can be adjusted manually in relation to the clock time scale.

With this design of the control element carriers, each of which has a pair of control elements, it becomes significantly easier than before to program a certain, for example often desired switching time for an electrical consumer, for example a heater, at any time of the day. The basic idea of the invention can be varied in many different ways and used with both annular and disc-shaped program carriers.

Embodiments of the invention will now be explained in more detail with reference to the drawing.

The switching clock shown in Figures 1 to 3 for use in a wall socket has a first embodiment of an annular program carrier 9.

The timer has a square housing 1 seen from above. A socket part 2 with contact pin 3 is arranged on the underside of the housing 1. A short pillar 4 with a triangular cross-sectional shape is arranged in each corner of the substantially box-shaped housing 1 on its upper side. 10 15 20 25 30 35 40 512 687 3 An operating star wheel 15 is rotatably arranged in one of the four cut-off columns 4 (fi g 2). When operated, it alternately opens and closes an invisible electrical switch in the timer.

A substantially cylindrical wall socket 5, in which the plug of a connection cable to an electrical device to be controlled can be inserted, is centered on the upper side of the housing. It is immovable but removably attached to the housing 1. Furthermore, a zero marker 6 directed towards the axis of the control star wheel 15 is arranged on the upper edge of the wall socket shell 5 to serve as a reference when the program carrier 9 is set to the clock time.

From fi g 2 it appears that the housing 1 with the socket part 2 and the four short pillars 4 in its upper wall 16 'has two holes 16 for the contact pins on a socket and contact spring brackets 17 for the earth connection. A circular guide rib 18 for the program carrier 9 is arranged on the upper side of the housing 1 concentrically with the central axis 1 'of the housing. A gear 20, which is driven by a time drive means arranged in the housing, preferably a synchronous motor, projects through a hole 16 'arranged between the guide rib 18 and one of the short pillars 4 and drives the program carrier 9. The control star wheel 15 is arranged in the mantle region of a of the cut pillars 4 and is operated by the operating elements of the program carrier 9.

One of your parts built program carrier 9 has a one-piece annular basic body 19 of plastic. The base body 19 is provided with a gear ring 21 on the end of the cylinder 1 facing a housing 1. An annular ring wall 30. The gear ring 21 cooperates with the gear gear 20.

The inner ring wall 30 is provided with an outwardly directed radial shoulder 32 at its opposite end. The shoulder 32 connects a radially further outwardly located second ring wall 33 to the inner ring wall 30. An outer support ring 35 having a radial support surface 39 is connected to the second ring wall 33 via a radial ring bridge 34. Between the inner ring wall 30 and the second ring wall 33, a downwardly open annular groove 36 is formed. An upwardly open guide groove 37 is located between the second annular wall 33 and the support ring 35. Several axial holes for inserting connecting pins 40 on a shell ring 7 are provided in the radial shoulder 32. By means of the connecting pins 40, which is fastened in the radial shoulder 32 with a rivet head 41 produced by thermoforming, the scaling ring 7 is fixedly connected to the base body 19.

The scaling ring 7, which at the same time also surrounds the wall socket bowl 5, is provided with the clock scale 8. From fi g 2e and fi g 3 it can be seen in more detail that the scaling ring 7 protrudes outside the second ring wall 33 in radial direction with a radial projection 45, which is provided with a ring gear 46 on its underside. The radial projection 45 simultaneously serves as an axial abutment for a tire-shaped plastic rack 10. The adjusting ring 10 is provided with a radially inwardly projecting annular shoulder 47, which projects below the radial projection 45 and its ring gear, and which engages with the gear ring 46 with fls, such as axial elevations arranged coupling teeth 48 in such a way that the engagement is rotation-proof resilient, and thus releasable, at least in the direction of rotation of the drive. The ring gear 46 is preferably provided with a locking tooth path, which allows the adjusting ring 10 to be rotated relative to the scaling 7 and the base body 19 in the direction of travel of the program carrier 9.

Such rotation, which is normally done when other switching times are to be set, is facilitated by a sliding ring 50 being mounted on the annular support surface 39 of the support ring 35. The sliding ring 50 has an L-shaped cross-sectional profile. The radial leg rests on the support surface 39, while the JM «vi» | II uulm H i .. min i.

.- »LMÛUH i. __ i * 'I: Hl l fi zlill”. W: El 10 15 20 25 30 40 512 687 4 the axial leg is guided along the inside of the support ring 35. From fi g 3 it appears that the support ring 35 with the inserted sliding ring 50 is located radially below the ring shoulder 47 on the adjusting ring 10.

Several, preferably four, compression springs 51 are arranged between the sliding ring 50 and the ring shoulder 47 to keep the coupling teeth 48 of the adjusting ring 10 in axial engagement with the toothed ring 46 of the shell ring 7. The positions of the compression springs 51 are secured by the compression springs 51 mounted on guide pins 52 on the sliding ring 50 and projects into the bottom hole 53 in the underside of the annular shoulder 47.

Thanks to this arrangement, the scaffold 10 can be moved with axial suspension along the base body 19 when the toothed grip with the peeling ring 7 is to be released, so that the adjusting ring 10 can be rotated freely relative to the peeling ring 7 and the basic body 19 in both directions of rotation.

A coupling operating element 12 and a disengaging operating element 14 are formed, each having a tooth-shaped radial projection on the outer circumferential surface of the adjusting ring 10 in one piece therewith. They form a pair of control elements and have a mutual distance corresponding to a certain switching time in the circumferential direction. Furthermore, the operating elements 12 and 14 are azially displaced from each other in order to be able to engage with the various teeth of the control star wheel 15 and in consequence to effect the connection and disconnection processes. A connection marker 11 and a disconnection marker 13 are arranged on the edge surface at the upper edge of the adjusting ring 10. They are directed towards the clock time scale 8 and show on it the switching times that apply to the operating elements 12 and 14.

The time can be set by turning the entire program carrier 9 clockwise. The scaling ring 7 provided with the rotation is then set on the zero marker 6, and thus on the correct clock time.

A new switch-on time, and thus also a new switch-off time, is set by first pushing the adjusting ring 10 towards a stop, so that the gear engagement ceases, and then turns.

Because the switching element 12 is mechanically rigidly connected to the switch-off element 14, no individual control pins or control riders fl need to be replaced and inserted in new positions when the switching clock is to be reprogrammed.

If a different switching time is desired, the adjusting ring 10 with a switching time of, for example, 2 hours can be exchanged for another switching ring with the desired switching time, for example 2.5 hours. The only thing required here is that connecting elements with position locks are arranged on the scaling ring 7 instead of the riveted connecting pins 40.

It is also possible to use adjusting rings with several pairs of control elements.

A lighting element, for example a glow lamp 55, can be arranged in the base body 19 in diametrically opposite position to the gear 20 to illuminate the shell ring 7. In this case, the base body 19 and the shell ring 7 must consist of transparent material.

In order to be able to set different lengths of switching-on periods using a single adjusting ring, the pair of control elements can be arranged on a separate program ring, which is switched on the adjustable ring.

In the exemplary embodiment shown in Fig. 4, the switching clock intended for insertion into a wall socket is provided with a program carrier 9/1, which is formed by a ring body in one piece. The clock scale 8 is arranged on the upper side of the program carrier 9/1, as well as plug holes 58, 59 for control pins 60 and 61. The plug holes 58, 59 are arranged along a concentric connection circuit and a concentric disconnection circle. with equal distances.

However, the operating pins 60, 61 cannot be inserted individually but only in pairs by being rigidly connected to each other to actuating element pairs 62 by means of an operating element carrier in the form of a stirrup 63 or a grip part 65, so that an operating pin 60 is inserted in an insert hole 59 on the engagement circle and the second control pin 61 is simultaneously inserted into a longer or shorter distance insert hole 58 on the engagement circle. In this way, a predetermined switch-on time is programmed with fixed switch-on and switch-off times.

In addition to the two control pins 60, 61, there may be a centering pin 64, which can facilitate correct insertion. In this embodiment, it is simple and also from a cost point of view acceptable without problems to have several control element carriers with equal and! or different coupling distances.

The program carrier 9/2, also shown in fi g 5 for a timer which can be inserted into a wall socket, also has a clock time scale 8 on its upper side. It is provided along its circumference with axial insertion grooves 67, to which belong a square insertion hole 6 arranged on a concentric inner circle. Program carriers 9/2 of this kind are known per se and are normally used together with operating riders 70, 71, each of which one has a longer insert leg 72 for the axial insert groove 67 and a shorter insert pin 73 with a suitable cross-sectional shape for the insert hole 68. The coupling riders 70 differ from the coupling riders 71 only in that their radially outwardly projecting heavy actuating elements 74 and 75 are arranged at different axial heights of the insert legs 72.

The control riders 70, 71 used in this case are rigidly connected in pairs by means of a control element carrier in the form of a bridge 77 so that they form a pair of control riders 76, in which the two individual riders have a fixed coupling distance and can only be knitted in common. Even in this embodiment, it is possible without problems to have fl your control rider pairs 76 with the same or different coupling distances for replacement purposes.

The program carrier 9/3 shown in fi g 6 differs from the program carrier 9/2 only in that a concentric guide groove 54 is arranged instead of the insertion holes 68 arranged along a circle. Correspondingly, the actuator pair 80 is instead of the insertion rider pair 80. pins 73 provided with an arcuate going guide strip 81, which is inserted into the guide groove 54 when the insertion legs 72 are guided in the axial insertion grooves 67.

Otherwise, the insertion rider pairs 80 are designed in the same way as the insertion rider pairs 76. Different long engagement times are achieved by means of control rider pairs 80 with different length guide strips 81 and bridges 77.

Fig. 7 shows a program carrier 9/3 with two control rider pairs 80 and 80/1, which are rigidly connected to each other by means of a ring bridge 82.

In this design, two equal or different length switching cycles can be programmed with a predetermined time interval on the program carrier. It can include two or fl your maneuvering pairs 80 and 80/1, which are rigidly connected to each other via the connecting bridge 82 and can be optionally spaced apart.

The operating rider pair 76/1 shown in Fig. 8 substantially corresponds to the operating rider pair 76 in fi g 5. The only difference is that a gripping element 78 is provided to facilitate strapping.

In the exemplary embodiment shown in fi g 9 to 12, an annular program carrier 9/4 is used, which is constructed in substantially the same way as the program carrier 9 in fi g 1 to 3. However, in addition to the shell ring 7 with the clock scale 8, the basic body 19/1 has a coupling element in in the form of a toothed ring 97 formed by ratchet teeth on the outside of the support ring 35. A control element carrier 90 engages the ring gear 97. In this case, the scaling ring 7 need not be provided with a tooth path.

The control element carrier 90, which like all other ones is made in one piece of plastic, is essentially designed as a two-legged circular ring segment with h-shaped cross-sectional profile and two mutually concentric, arcuate moving wall elements 92, 93, which are rigidly connected to each other by a radial bridge 94. A grip strip 94 'adapted to the outer curvature of the shell ring 7 is formed on the radial bridge 94. It is provided with a connection marker 11 and a disconnection marker 13 on its upper edge surface. The switching marker directed towards the clock time scale 8 includes an operating element 95, which is designed as an operating finger and is formed on the outside of the wall element 92 so that it protrudes radially. In an analogous manner, a control element 96 belongs to the disconnection marker 13. It is arranged on the outside of the wall element 92 in the same way as and at a fixed, unchanging coupling distance from the control element 95. Between the two wall elements 92 and 93 there is a cross section rectangular groove 99, which is wider than the support ring 35, so that a U-shaped profiled sliding strip 98 can be inserted fittingly into the groove 99 and abut against the upper support surface 39 of the support ring 35.

In order for the sliding strip 98 to be carried safely when a moving element carrier 90 is moved along the support ring, end strips 101 and 102 are arranged at each of the two ends of the groove 99.

They abut radially against the support ring 35 and enclose the slide strip 98 therebetween. Similar to the sliding ring 50, the sliding strip 98 is provided on its upper side with two guide pins 52, on which compression springs 51 are arranged. The compression spring shafts 51 press the radial bridge 94 against the underside of the excess annular radial projection 45 on the scaling 7, which in this case is not provided with a coupling tooth path but is smooth on the underside.

The gear ring 97 serving as a coupling tooth path is arranged in the lower part of the support ring 35. The cooperating tooth path 103 on the control element carrier 90 is located at the lower end of the inside of the wall element 92. The tooth path 103 can, in the manner shown in fi g 14, be arranged as sp your locking teeth on both ends of the wall element 92. In the normal position shown in Figs. 10 and 11, the two tooth paths 97 and 103, which each consist of ratchet teeth, are in engagement with each other, so that the control element carrier 90 is safely carried by the program carrier 9/4 driven clockwise with the correct time, respectively. / 1.

By depressing the control element carrier 90 axially, the gear engagement 97/103 can be suspended briefly, so that the control element carrier 90 can be moved to an operating position along the support ring located at another time.

The coupling element carrier 91 shown in Figs. 13 to 15, which also fits on the program carrier 9/4, differs from the control element carrier 90 only in that it has a thicker and slightly longer inner wall element 93/1, which abuts guided towards the inside of the support ring 35 and supports against the ring strip 34. The control element carrier 91 cannot be moved axially along

Claims (19)

10 15 20 25 30 35 40 512 687 7 the support ring 35. The outer wall element 92/1 is therefore thinner, and thereby more elastic, so that the cooperating tooth path 103 can slide over the ratchet teeth in the ring gear 97 when the control element carrier 91 is moved forward along the support ring 35. It can be seen from Fig. 13 that in this case it may be appropriate to extend the support ring 35 axially up to the radial bridge 93 of the operating element carrier 91 in order to make the control more efficient. In fi g 16 to 18 a program carrier 9/5 is used, the structure of which is similar to the program carrier 9/4. However, its base body 19/5 has only an inner ring wall 30 and a support ring 35/5, which are directly connected to the inner ring wall 30 via a radially wider ring bridge 34. Furthermore, the support ring 35/5 has at its upper edge an inner ring gear 97/5. , with which a cooperating gear track 103/5 on a control element carrier 106 is in radially resilient engagement. The cooperating toothed path 103/5 is arranged on the gripping strip 94 'against the support surface 39/5 of the supporting surface located on the end side. The two operating elements 95 and 96 are arranged on the outside of the grip strip 94 '. The grip strip 94 'is connected via a radial connecting bridge 107 to a radially resilient ring strip 108, which in turn is attached to a guide ring 109. This surrounds the inner ring wall 30 and guides it. The connection makes it possible to cancel the gear engagement between the ring gear 97/5 and the cooperating gear track 103/5 by pushing the control element carrier 106 radially inwards. When the gear engagement is released, the control element carrier 106, which is connected to the guide ring 109 and is controlled by it, can be moved along the support ring 35/5 to an operating position at another time. When the grip strip 94 'is released, the resilient ring strip 108 resets the gear grip. Other spring elements with the same or similar function can be used instead of the spring strip 108. Arrows 43 and 44 show the direction of rotation of the different program carriers 9 to 9/5.
