Wall or table clock with a fixed on the clock plate

Bezel

The invention "relates to wall or table clocks. There are two types of bezel in such clocks known. One type is firmly attached to the housing ;, the other type is with a hinge on the clock— shield attached so that it can be opened together with the glass cover. The first type is the pointer adjustment made by specially provided actuators on the rear of the housing or on a side surface.

In the second type, the adjustment can be carried out directly on the pointers. It is also known on glass lids, preferably made of synthetic glass at the edge, protruding locking noses are to be formed directly, which in Locking grooves, which are molded into the watch plate, can be inserted in the manner of a bayonet, so that the glass cover is detachable from the clock plate and thus the hands are accessible.

For aesthetic reasons, however, it is often used as a limitation for the glass cover on the clock plate a bezel desired. It is therefore the object of the invention to create a wall or table clock that is based on Your watchshiid has a fixed bezel to which the glass cover is detachably attached, which simply designed and thus inexpensive to manufacture and assemble from their individual parts in a simple manner is.

This object is achieved in that the bezel is arranged with at least two distributed around the circumference Plug-in pin-socket connections in the seat of the bezel and the watch face is one element of the spigot socket members

is elastically flexible and can be connected to the counterpart with an adhesive fit, and that on the edge of the glass cover itself known VersehluBnasen are formed, which in corresponding = Engage the corresponding locking grooves in the steady rest.

Such a plug-in pin-socket connection can be produced particularly easily, especially if in an advantageous embodiment of the invention, the Bezel is an injection-molded plastic part. Once the bezel has been pressed on, it can no longer be pulled off easily, because the frictional force is pushed into one another with an adhesive fit Pins and bushings prevent this.

According to a preferred embodiment of the Erg are located on the bezel plug-in pins that

inserted into corresponding holes on the clock child, elastically deformable sockets are inserted, the inner diameter of which is slightly smaller than the tenon diameter. The plug-in pins are preferably molded onto the steady rest. However, it is also possible to use plug-in pins made of metal, which are then firmly connected to the bezel, preferably during the injection molding process in these are injected.

The invention will now become more apparent from the description of exemplary embodiments that follows with reference to the drawing

8 shows a section along VIII-VIII in FIG. 7.

The drawing shows a watch plate 10, on which one made of plastic is concentric to the pointer shaft bore 11 Bezel 12 made by injection molding is attached. The pointer space is closed off by a glass cover 13. From the steady rest on its seating surface 14 three plug-in pins 15 protrude, which in the present case around each other Are offset by 120 °. The clock plate is provided with holes 16 which are on the same diameter as the plug-in pin and are also offset from one another by 120 °. The diameter of these holes is larger than the journal diameter. However, so that the bezel 12 can be fastened with a tight fit on the watch plate, are in the holes Made of an elastic material sockets 17 are used, the inner diameter of which is slightly smaller than the diameter of the pin 15 * so that the indented The pegs get a firm hold here and the bezel cannot be detached from the watch plate after being attached can.

To when inserting the pin 15 into the sockets 17 to avoid these being pushed through the clock face are, the sockets are provided with an outwardly protruding collar edge l8, which is on a corresponding Edge 19 of the stepped hole l6 plant finds.

So that the glass cover I3 can be detachably connected to the bezel 12, it carries two known locking lugs 20 on its circumference, with which it is inserted into angled slots 21 for the purpose of a bayonet-like locking, which are formed in the inner surface of the bezel. The height of the locking part of the angled slot 21 is preferably chosen so and its upper boundary surface is inclined at an angle that the glass cover is pulled firmly onto the watch plate during locking and is thus held in a self-locking manner.

7 and 8, another embodiment example of the invention is shown, the watch plate is here unchanged. It has the same stepped hole 16, but this is not like the one described above In the case of an elastic bushing, an insert part 22 with a pin 23 protruding beyond the shield surface is used. The bezel 24 consequently points to the pin

Corresponding bores 25, the diameter of which is slightly smaller than the pin diameter. Because in general the bezel is made of a hard plastic, the insert part 22 with pin 23 is made of an elastic Resilient material made, which is when the bezel 24 is placed on the watch plate under Danish deformation press firmly into the bore 25.

This bezel 24 is also provided with a locking groove 21 for the bayonet locking of the glass cover 13 equipped with its molded locking lugs.

The bezel can be electroplated with a metal coating to achieve special aesthetic effects will. It can also be coated with a metal paint or some other color.
