Abstract

A loupe support system includes a frame (12) which can be mounted at the head of a user and at which a holding device (18) is mounted, an elongated support element (30, 31, 68) which, at its central region, is supported at the holding device (18) such that it can rotate about its longitudinal central axis, wherein a respective loupe ocular (34) is mounted at the support element (30, 31, 68) on each of both sides of the holding device, and a light mounting element (22) supported at the holding device (18) such that it can rotate about a rotary axis being coaxial with respect to the longitudinal central axis of the support element (30, 31, 68).

Claims

1. A loupe support system comprising

a frame on which a holding device is mounted;

an elongated support element having a longitudinal central axis and a central region, said elongated support element being supported at said central region on said holding device such that it can rotate about a first rotary axis being coaxial to said longitudinal central axis, wherein a respective loupe ocular is mounted at the support element on each of both sides of said holding device; and

a light mounting element supported at said holding device such that it can rotate about a second rotary axis being coaxial to said longitudinal central axis of said support element, wherein

at said holding device a sleeve portion is provided, at both sides of which a corresponding cylindrical space being coaxial with respect to said longitudinal central axis of the support element is formed, each cylindrical space opening in an respective end side of said sleeve portion and being limited within said sleeve portion by a cylinder bottom, wherein said cylinder bottoms are spaced apart from one another, whereby a clearance is formed in said sleeve portion;

a circumferential slot is formed over a partial area of the outer circumference of said sleeve portion, said circumferential slot opening into said clearance;

in said clearance a disk element is arranged such that it can rotate, wherein at an outer circumference of said disk element a projection is formed extending through said circumferential slot outwardly, wherein at said projection a fastening device for fastening a light is provided outside of said sleeve portion;

in said cylinder bottoms and said disk element coaxial through holes are provided, through which an axis having a first and a second end extends;

said first and second ends of said axis are each connected to one corresponding end of a support portion of said support element such that they are fixed against rotation;

in each of said cylindrical spaces a respective pressure disk surrounding said axis is arranged adjacent a corresponding cylinder bottom, at least one pressure projection being provided on the pressure disk such that it extends in an axial direction parallel to said longitudinal central axis through a corresponding through hole in a corresponding cylinder bottom and engages said disk element; and

a resilient device is provided in each cylindrical space, one end of said resilient device engaging an end side of a corresponding support portion facing said resilient device, wherein the other end engages said pressure disk.

2. The loupe support system according to claim 1, wherein a clamping device is provided which is formed and arranged such that said elongated support element and said light mounting element each remain in a respective rotary position after having been rotated.

3. The loupe support system according to claim 1, wherein said resilient device is formed by a disk spring package through which said axis extends.

4. The loupe support system according to claim 1, wherein an end of each of said support portions extending into a corresponding one of said cylindrical spaces is formed by a cylindrical portion which is adjoined by a cylindrical collar, the outer diameter of said cylindrical collar is larger than the outer diameter of said cylindrical portion and corresponds to the inner diameter of said cylindrical space, and wherein at said cylindrical portion a ring seal is arranged which engages said cylindrical portion and the inner wall of said cylindrical space.

5. The loupe support system according to claim 1, wherein said loupe oculars are mounted such that they can slide in the longitudinal direction of said support element.

6. The loupe support system according to claim 1, wherein a light is mounted at said light mounting element such that the optical axis of said light lies in the plane of the optical axes of said loupe oculars.

7. The loupe support system according to claim 1, wherein said holding device comprises a pivoting bracket, one end of which is articulated at said frame, and a connecting arm, one end of which is articulated at the other end of the pivoting bracket.

8. The loupe support system according to claim 1, wherein said frame is an eyeglass frame having a bridge, wherein said holding device is mounted at said bridge.
