I need to replace the chainrings because the chain slipped several times while riding due to heavy wear. However, I have not been able to find similar ones. Perhaps someone of you knows where to find them.

You have vintage chainrings. Probably easier to find a replacement crankset. Those bolts are not the standard size.

That can help you identify the BCD, but you probably won’t be able to find new parts.
Were those chainrings riveted to the crank spider?
looks like a [Silstar](https://velobase.com/ViewComponent.aspx?ID=79B805C9-EE79-47B1-A8CD-5CB669CE950B&Enum=115&AbsPos=2) design.
