Equipment of a wristwatch, especially for children

The innovation relates to the equipment for an electronic clock, primarily for children, with the combination an electronic clock module with a digital display and operational clock mechanism itself, i. with the crystal oscillator, the electronic circuit and also the clock battery together with several of them exchangeable outer housings.

Typically, electronic wristwatches also come complete with a watch module, case and strap. It is also known to provide individual complete children's watches with a housing or a watch face plate that the Has the shape of an animal or the like. However, it is up to the innovation to satisfy the children's desire for electronic Promote wristwatches.

The innovation is therefore characterized in that the equipment comprises a single electronic watch module and a plurality of watchbands and housing for the module, each G casing _e and the associated strap are made as a whole of flexible synthetic resin, each unit consisting of housing and ribbons an appearance possesses, which differs from the one or the other and each case has an identical cut in its back, in which the clock module can be inserted interchangeably.

According to a preferred embodiment of the innovation, the clock module is in a cup-shaped housing with externally protruding annular projections used around the bottom of the housing. Such a case

can be made of rigid plastic and provides good mechanical protection for the watch module. In addition, the bottom of the case, including the protruding protrusions, can form the back of the watch ", when the clock module is in the plastic housing ". This gives a neat lock for the clock and mechanical protection for the sensitive parts of the module.

A setting device for the time display is required for the clock module. The module often includes switches corresponding push buttons or the like Step out of the watch case. Such an arrangement is possible with watches according to the innovation. However, this will not "preferred because such pushbutton switches or the like Hinder interchangeability of the watch module from one watch case to another.

According to a preferred embodiment of the innovation, the clock module has a conductive contact plate which contains a disc which covers the capsule and is cut out so that the time can be read and is also provided with a plurality of curved metal studs that curve downward around the module are una of which one touches the battery pole of the watch case. Touch at least two others when pressing Parts of the electronic circuit, e.g. a metal strip on the side of the watch case, which makes a switch, with which the clock can be set. Other curved metal strips are used to attach the contact plate to the Module or on the capsule. The module is preferably provided with a rib that fits into a corresponding groove can be inserted in the edge of the incision in the back of the watch case. The module snaps firmly into the

housing or is pressed into it and the rib on the module and the corresponding recess in the housing facilitates the correct insertion of the module. The housing is provided with a cutout part so that the Time can be read.

The edge of the cutout in the back of the watch case can also be cut with one or more Parts, preferably with inclined surfaces, be provided in order to facilitate the removal of the module from the cutout.

The tape "fastening mechanism includes, for example at one end a row of spaced, punched holes and at the other end a protruding one Pin that can be put in one of the holes and a raised loop through which the other end of the strap can pass through and through which the other end of the strap is held close to the body of the strap when the watch is worn, will.

For example, if the watch band and case are to be used by children, they can be in the shape of an animal, of an animal head, cartoon or television symbol. There can be several watch straps with cases in the form of different Representations, e.g. several different animals can be bought together with a single clock module, see above that the child choose a special band with a housing in the shape of a corresponding animal and insert the module into the Install the tape and then place the tape in one with a housing in the shape of another animal by removing the module from the first housing and inserting it into the second.

An example of equipment according to the innovation is with Using the drawings. In these is:

FIG. 1 shows the front of a combination of watch strap and case;

FIG. 2 shows the back of the watch strap and the housing according to FIG. 1;

FIG. 3 shows an enlarged perspective view of a clock module which can be removed in the summary can be used from tape and housing according to Figures 1 and 2; and

Figure 4 is a section of the module which is inserted in the case and the way in which the clock display is set.

Figures 1 and 2 show the combination of volume 1 and housing 2. The housing has the shape of a lion's head. On the back of the housing there is a round cutout 3 into which a clock module 10 is inserted can be (Figure 3).

The module itself contains an outer, cup-shaped Plastic housing 11, in which the electronic watch parts 12, a display 20, a battery for operation 24 dei electronic circuit, the crytal oscillator and the like. are located. These electronic components are common and are therefore not shown or described. the more sensitive electronic parts and the display are housed in the cup-shaped plastic housing 11 for protection. As FIG. 4 shows, the housing fits well into the cutout 3.

The housing 11 "has a back around its bottom outwardly protruding projection 11a, which abuts the back of the housing 2 when the clock module 10 is in Housing is located. In addition, the bottom of the housing 11 and the projection 11a close the cutout 3 in FIG Back of the clock and form the back of the clock when the module is in cutout 3.

In the edge of the cutout 3 there are small cutout parts 9 (Figure 2). When removing the clock module 10 from the respective watch case 2, these cutout parts make it easier to remove the module. Consequently a user can use a pointed object or the like. insert into these cutouts 9 and the module 10 out of the cut by levering against the underside remove the projection 11a.

The top of the clock module 10 is covered by a copper contact plate 13. This is practical around and around its edge there are several pegs 14 to 18. These are bent downwards and some of them, e.g. the peg 18, are printed in small cutouts 18a located in the outside of the housing 11 thus keeping the electronic parts of the module and the contact plate in place.

Another pin 14 leads in the cutout 14a of the housing wall downwards and its end is downwards and under the Clock module bent, which is in, -contact with one pole of the Battery 24 for operating the module is located. The whole plate 13 is thereby at the potential of this battery pole held.

Other tenons such as 15 "through 17 are bent downward and work as a switch. Therefore, under normal circumstances, these pins do not touch any electronic parts Circuit in the module, but can come into contact with these parts for example by means of a resilient pointed object such as a ballpoint pen when making settings such as the time indicators should be. This arrangement is very convenient for setting the clock display, since there are no protruding ones Push buttons and the like are necessary, which influence the easy interchangeability of the module 10 and the housing 2 would.

The contact plate 13 is also with a cutout 19 through which the time display 20 of the module can be viewed.

An opening 4 extends through the watch case 2 for viewing the display 20 from the front of the case so that when the module 10 is inserted into a housing, the display 20 is correctly aligned with the opening 4, there is a groove 8 in the edge of the cutout 3 around a small rib, not shown To include module 10.

The housing 3 and the band 1 consist of one piece of elastic plastic. Around the band around the wrist To fasten around the carrier, the tape 1 is provided with a plurality of holes 5 at one end 21. At the other End 22 of tape 1 is a loop 6 and a raised pin 7. One around the wearer's wrist bound tape can be pulled the end 21 through the loop 6 and one of the holes 5 can be at Pin 7 to secure the band to your wrist.

Typically, an equipment according to the innovation contains a single clock module 10 and several, e.g. six combined watch straps 1 and case 2, which differ in appearance. Then a carrier, e.g. a customer, choose, and swap the clock module from the case into another and so the equipment results a significant increase in the length of time a child finds this watch interesting. So you can access this Way with a single module, which is the most expensive part of a watch, a wide interesting and different one Areas of relatively cheap casing to increase the attraction of the watch to a Kini,
