Movement fastening for alarm clocks

The innovation relates to alarm clocks and concerns a clockwork fastening of the type with which dial and watch glass by means of a movement ring or the like that fits into the case, held in contact with the glass edge of the case and the work ring is fixed on the housing by arranging the fit for the alarm stop button. The conventional one Fastening is friction-locked, whereby the force required for this is generated via a screw connection. Manufacture and assembly of the parts in question is comparative expensive and also cumbersome because the mostly painted housings are easily scratched during assembly can.

The innovation provides a remedy in that the parking button socket is positively locked in its seat on the housing is attached by crushing the fit., while the movement carrier is resilient in the direction of the plane of the dial, for example by raising the edge of the hole on the case created seat for the stop button holder. The button frame is preferably made of elastic Plastic, is beveled at its insertion end and has a snap-in groove following this bevel, in which the raised edge of the hole of the housing fits. For resilient support of the work ring on the button socket can cut a pair of springy pingers perpendicular to the work ring perpendicular to its main plane be that on the seat for the parking button socket like pliers attacks with the mouth opening to the bottom of the case. As a result, a force component comes perpendicular to the plane of the dial comes about, which causes the watch glass and dial to fit snugly against the edge of the case. Instead of pincer-like The fingers surrounding the raised edge of the hole can also cut a resilient tongue out of the work ring and be folded into the plane of the housing wall, the tongue in this position at an angle to the main plane of the work ring runs and preferably arranged in such an angular position with respect to the mounting holes of the work carrier is that when screwing the work ring into its fastening

position is clamped under wedge effect.

The new type of fastening has the advantage that there are no threads on the work carrier and on the parking button socket and the interacting parts can be produced by drawing , punching and pressing or casting.

Other features and advantages of the. The innovation results from the following description of an exemplary embodiment , from the drawing and the protection claims. Show it:

Fig. 1 is a front view of an alarm clock case with an inserted work ring., But without a work,

Pig. FIG. 2 shows, in an enlarged illustration, a section along AA through the alarm clock holder arrangement ₃

Fig. 3 is a section along B-B through Fig. 1 with the representation of a first embodiment for the work carrier attachment to the Stop button holder,

Fig. 4 shows a detail of the stop button socket, Fig.5 > 6 and 7 in the same representation

Fig. 3 further training for the attachment of the work carrier on the stop button holder.

The ζ. B. drawn from sheet metal round housing of the alarm clock is denoted by 10, with 11 a work carrier ring, with 12 the dial provided with an edge 12a, at 13 the clock glass., which against the formed by beading Glass edge 10a rests on the inside of housing 10. As usual, the work carrier 11 is at the bottom by means of the feet 14 on the housing

10 screwed tight. For further fastening of the work carrier

11, the following precaution is taken: A push button 16, which is guided in a fit, so-called clasp I7, is used to operate the alarm clock holder 15. This button bevel I7 consists of an elastic plastic and is seated on the housing 10 by being pressed in; See Fig. 4. For this purpose, the button socket is beveled at its insertion end at 17a to a smaller diameter and this bevel is followed by the snap-in groove 17b, which is followed upwards by the broad collar 17c visible on the outside of the housing. ^{The raised edge 10a l of} the seat opening 10a for the button guide 17, which has been raised by deep drawing, fits into the snap-in groove 17b, so that the two parts are firmly connected to one another by a form fit.

Frictionally engaged around watch glass I3 and dial 12 to be pressed against the glass edge 10a on the housing 10 are on the work carrier 11 different types of resilient fastening means

(Fig. 3, 5j 6 and 7) attached.

In the embodiment according to Pig. J resilient pingers are cut on the work carrier 11 and bent perpendicular to the main plane of the ring 11, in such a way that they ^{encompass the raised edge 10a f} like pliers, but in such a way that the attack surfaces 11b form a mouth that opens up to the case bottom and thereby one perpendicular to the plane of the dial directed pressure force component arises.

The connection between the edge of the hole 10a ¹ and the work carrier ring 11 is created in a similar manner in the embodiment according to FIG. the parts of the work carrier 11 encompassing the edge of the hole 10a ^{1 like pliers are denoted by 21b.}

In the embodiment according to Pig. 6 are on the pincer-like parts J1b of the work carrier 11 barbs 51c attached.

In the embodiment according to Pig. 7, a spring tongue 41 is cut into the work carrier 11 and bent ^{1 out of its main plane into the plane of the housing wall 10.} The tongue 41 runs in an oblique direction

to the principal plane of the workpiece support 11 and in such angular position (not shown on the drawing) to the mounting holes on the mechanism carrier for screwing in the feet 14, that during the screwing of the work support 11 in. .. its fastening position the tongue 41 with its incline, tangential to the edge of the hole 10a ^! starts up (dashed position) and is then clamped by wedge effect. As a result, the dial and glass come into close contact with the glass edge 10a of the case.
