Abstract

A head magnifier is provided, comprising magnifying optics as well as a coupling mechanism for attaching the magnifying optics to a head mount which can be placed on a user'"'"'s head. The coupling mechanism has a swivel mechanism enabling swiveling of the magnifying optics relative to the head mount about a swivel axis, and an adjusting mechanism enabling adjustment of the distance between the magnifying optics and either the swivel axis or the head mount by moving the magnifying optics along a longitudinal axis. The swivel mechanism provides a swivel angle range for the magnifying optics and enables setting and fixing of different swivel angles of the magnifying optics, said angles falling within the swivel angle range. The swivel axis extends in front of the user'"'"'s head in the mounted condition of the head magnifier, and the adjusting mechanism telescopes with the magnifying optics mounted to the mechanism'"'"'s front end.

Claims

1. A head magnifier comprising magnifying optics as well as a coupling mechanism for attaching the magnifying optics to a head mount which can be placed on a user'"'"'s head;

wherein the coupling mechanism comprises a swivel mechanism enabling swiveling of the magnifying optics relative to the head mount about a swivel axis, and an adjusting mechanism enabling adjustment of the distance between the magnifying optics and one of the swivel axis and the head mount by moving the magnifying optics along a longitudinal axis,

wherein the swivel mechanism provides a swivel angle range for the magnifying optics and enables setting and fixing of different swivel angles of the magnifying optics, said angles falling within the swivel angle range,

wherein the swivel axis extends in front of the user'"'"'s head in the mounted condition of the head magnifier,

wherein the adjusting mechanism comprises a telescopic rod, with the magnifying optics being mounted to a front end of the telescopic rod, and

wherein the swivel mechanism enables swiveling of the magnifying optics about a further swivel axis and the adjusting mechanism enables adjustment of the distance between both swivel axes by moving the magnifying optics along the longitudinal axis.

2. The head magnifier as claimed in claim 1, wherein the further swivel axis extends in front of the user'"'"'s head in the mounted condition of the head magnifier.

3. The head magnifier as claimed in claim 1, wherein the telescopic rod enables continuous distance adjustment.

4. The head magnifier as claimed in claim 1, wherein the magnifying optics comprise two oculars, each of said oculars being assigned to one of the user'"'"'s eyes.

5. The head magnifier as claimed in claim 4, wherein the two oculars are attached to an ocular support which can be swiveled about the swivel axis (axes).

6. The head magnifier as claimed in claim 5, wherein the front end of the telescopic rod is connected to the ocular support in the middle between both oculars.

7. The head magnifier as claimed in claim 1, wherein the magnifying optics are hinge connected in a swivelable manner to the front end of the telescopic rod.

8. The head magnifier as claimed in claim 1, wherein the front end of the telescopic rod comprises an ergonomically shaped gripping region.

9. The head magnifier as claimed in claim 1, wherein the coupling mechanism is releasably connectable to the head mount.

10. The head magnifier as claimed in claim 1, wherein the head mount is part of the head magnifier.

11. The head magnifier as claimed in claim 1, wherein the swivel angles are continuously adjustable within the swivel angle range.

12. A head magnifier comprising magnifying optics as well as a coupling mechanism for attaching the magnifying optics to a head mount which can be placed on a user'"'"'s head,

wherein the coupling mechanism comprises a swivel mechanism enabling swiveling of the magnifying optics relative to the head mount about a swivel axis, and an adjusting mechanism enabling adjustment of the distance between the magnifying optics and either the swivel axis or the head mount by moving the magnifying optics along a longitudinal axis,

wherein the swivel mechanism provides a swivel angle range for the magnifying optics and enables setting and fixing of different swivel angles of the magnifying optics, said angles falling within the swivel angle range,

wherein the swivel axis extends in front of the user'"'"'s head in the mounted condition of the head magnifier,

wherein the adjusting mechanism comprises a telescopic rod, with the magnifying optics being mounted to a front end of the telescopic rod, and wherein the magnifying optics are hinge connected in a swivelable manner to the front end of the telescopic rod.

13. The head magnifier as claimed in claim 12, wherein the swivel mechanism enables swiveling of the magnifying optics about a further swivel axis and the adjusting mechanism enables adjustment of the distance between both swivel axes by moving the magnifying optics along the longitudinal axis.

14. The head magnifier as claimed in claim 13, wherein the further swivel axis extends in front of the user'"'"'s head in the mounted condition of the head magnifier.

15. The head magnifier as claimed in claim 12, wherein the front end of the telescopic rod comprises an ergonomically shaped gripping region.

16. A head magnifier comprising magnifying optics as well as a coupling mechanism for attaching the magnifying optics to a head mount which can be placed on a user'"'"'s head,

wherein the coupling mechanism comprises a swivel mechanism enabling swiveling of the magnifying optics relative to the head mount about a swivel axis, and an adjusting mechanism enabling adjustment of the distance between the magnifying optics and either the swivel axis or the head mount by moving the magnifying optics along a longitudinal axis,

wherein the swivel mechanism provides a swivel angle range for the magnifying optics and enables setting and fixing of different swivel angles of the magnifying optics, said angles falling within the swivel angle range,

wherein the swivel axis extends in front of the user'"'"'s head in the mounted condition of the head magnifier,

wherein the adjusting mechanism comprises a telescopic rod, with the magnifying optics being mounted to a front end of the telescopic rod, and

wherein the front end of the telescopic rod comprises an ergonomically shaped gripping region.

17. The head magnifier as claimed in claim 16, wherein the swivel mechanism enables swiveling of the magnifying optics about a further swivel axis and the adjusting mechanism enables adjustment of the distance between both swivel axes by moving the magnifying optics along the longitudinal axis.

18. The head magnifier as claimed in claim 17, wherein the further swivel axis extends in front of the user'"'"'s head in the mounted condition of the head magnifier.

19. The head magnifier as claimed in claim 16, wherein the telescopic rod enables continuous distance adjustment.

20. The head magnifier as claimed in claim 16, wherein the magnifying optics are hinge connected in a swivelable manner to the front end of the telescopic rod.
