FIELD OF THE INVENTION The present invention relates to binoculars for attaching to spectacles.

Such binoculars attached to eyeglasses 10 are intended to facilitate precision work such as the work of a dentist or a fine mechanic. The drawbacks of known binoculars are the complex structure and excess weight, and the visual field limitation caused by the magnifiers, so that they have to be turned aside every time they want to look at 15 without magnification.

It is an object of the invention to provide eyeglass binoculars which are simple in design, lightweight, inexpensive and, above all, obscure the field of vision, so that the gaze can easily be directed past the magnifying glass to the same object that has just been viewed through the magnifying glass.

This object is achieved by the features set forth in the appended claims 1 to 25. The dependent claims disclose preferred embodiments of the invention that serve the individual alignment of the magnifiers so that said minimal field of view coverage can be utilized.

30 Ί:: ·. In the following, the invention will be illustrated by means of an exemplary embodiment with reference to the accompanying drawings, in which Figure 1 is a top plan view of binocular lenses according to the invention attached to spectacles; 104656 2 Figure 2 is a front view of the binocular looms of Figure 1; Fig. 3 is a side view of the same binoculars; w 5 Figure 4 illustrates in more detail the mounting arms of the magnifiers with hinges and adjustment possibilities; and Figure 5 is a sectional view taken along line V-V of Figure 4.

The binocular lenses 2 are attached by a mounting body 1 to the nose cap 17 of the eyeglasses. The lens cap 2 'extending also extends at an external angle at a sector angle substantially equal to the sector angle drawn on the edge of the ocular lens. In this case, the visual field limitation caused by the magnifiers is minimal. The user can look through the magnifiers 20 or past at their own discretion with just a slight gaze and head rotation.

Loop sheaths 2 'may be tubes of thin wall thickness having a conical hex corresponding to said sector angle. The material of the loop sheath may be metal, fiber reinforced plastic, etc. The cross section of the loop sheath may be circular, oval or angular.

The lugs 2 are attached to flat transverse arms 3, which can be bent at the hinge points 4, which are metal I, which are deformed when bent. The hinge points 4 may be of a different material than the arms 3, e.g., metal rods embedded in the arm material, e.g. The axes 35 of the hinges 4 are selected so as to control the bending of the arms 3 so that, in different positions of the arms 2, their central axes intersect at substantially the same distance from the binocular arms 2. The focus of the arms is always maintained when adjusting the distance between the arms.

The transverse arms 3 are connected at their center between the hinges 4 to a longitudinal arm 9 which also has a hinged metal hinge 12 at its junction. . The arm portion 7 is connected by a bendable metal hinge 5 to a slot-like fastener 6 which can be inserted from above into a metal connector 15 having grooves 16 on its sides, correspondingly shaped by the inner surfaces of the slot 6. With this quick coupling 15, the binoculars are easily removable and reattachable. The small and discreet metal connector 15 may be permanently attached to the nose cap 17 of the eyeglasses. The connector 15 may be attached to a variety of eyeglasses using a soft metal clamp 14, 20 having a loop engaging the nasal cap 17 and having its ends the threads of the screw 13 intersect the clamping bracket 14 into the material. Such a connector is compact, discreet and sturdy and is suitable for many types of 25-goggles.

The essence of the invention is that the Lips have a low field of view, which is achieved primarily by designing a thin-walled lens case to correspond to the sector angle of the field of view covered by the small eyepiece lens. In addition, the flat shape and location of the mounting arms are selected so as to minimize interference with the field of vision. At the same time, however, * the hinged arms allow their hinging points to allow for individual alignment and adjustment of the crotch 35 so that the focus of the magnifiers remains constant.

The length of the lugs can be, for example, 25-30 mm. The eyepiece lens may have a diameter of less than 10 mm, preferably about 8 mm. The distance between the eyepiece lens and the eye is in the order of 20 mm when the lens comes very close to the eyepiece lens.
