Raschig ring

Raschig Ring has serpentine connecting portions between parallel plates on which a plurality of protuberances are formed on the inner surfaces of the plates. The ring promotes the circulation of blood by accupressuring a finger by means of protuberances. 1. A ring having an inner circumference to be worn on a finger, said ring comprising

plate means having radially inward facing surface means and a plurality of radially inward directed protuberances extending from said surface means and spaced apart from each other, and

serpentine connecting means connected to said plate means and together with said plate means forming said ring.

2. A ring as in claim 1 wherein said plate means comprises a pair of substantially parallel plates and said serpentine connecting means comprises a pair of serpentine connecting members connecting said plates to form said ring.

3. A raschig ring as in claim 1 wherein said plate means are made of metal.

4. Ring as in claim 3 wherein said connecting means are joined to said plate means by welding.

5. Ring as in claim 2 wherein said serpentine connecting means provide sufficient elasticity to provide the ring with an adjustable diameter.

Referring to drawings, reference mark A designates a ring. Said ring A comprises the connecting portions, 10 10' preferably being made of serpentine elastic members and the plates 12, 12' which secures to both sides of the connecting portions by welding, etc. In said plates a plurality of protuberances 12a, 12a ' are formed in the inner surfaces thereof which come into substantial contact with the circumference of the finger 20. The plates 12, 12' and the plurality of protuberances 12a, 12a' are of metal, preferably of silver or aluminum.

To summarize the advantages obtained by the invention, the raschig ring A of this invention has the serpentine connecting portions 10, 10' being superior in elasticity, as shown in FIG. 1 and FIG. 2, so that it can be applied without regard to the thickness of fingers. Further, a plurality of protuberances 12a, 12a' are formed in the inner surfaces of the plates, so that where the ring is put on the finger 20, the circulation of blood of the finger can be promoted by accupressuring by means of protuberances.

As mentioned above, the raschig ring of this invention is a very useful invention in promoting the circulation of blood by putting pressure upon a finger as well having ornamental value.

The present invention relates to a ring, and more particularly it relates to a ring which can meet the various desires of a user by adding a functional element to the basic object of a ring as ornaments or accessories.

Conventional rings have heretofore been used to show the beauty in the shape of only ornaments or accessories. But, at present, they tend to be contained not only the ornamental element, but the functional element.
