Description

Swivel magnifier

The invention relates to a swivel magnifying glass with the features of the preamble of claim 1.

The lens part of the magnifier body of such a swivel magnifier is usually convex on both sides. These bulges show the insides of the both U-legs of the case have a concave bulge. The inner walls of the U-legs facing the magnifier body of the sheath are lined with a soft material, preferably flocked like a velvet, in order to swivel in the Magnifying glass body to avoid scratching the lens part through the inner walls of the U-legs of the case.

Injection molded plastic magnifier bodies are known to be particularly sensitive to scratches. It has been found that such Magnifying glass body after being swiveled in and out of the case multiple times, despite the velvety surface coating the inner walls of the U-legs can be scratched.

The invention is based on the object of designing a swivel magnifying glass of the type mentioned at the outset in such a way that the

the risk of scratching the surface of the lens part of the magnifier body is significantly reduced. The solution to this problem is based on the knowledge that the attachment of the Magnifying glass body on the case is usually made by riveting, the rivet at the same time being the pivot axis forms for the swiveling in and out of the magnifier body. This riveting creates the inner walls of the U-legs due to their dimensionally stable training or lining outside of the fastening area in the direction of the Lens part of the loupe body pulled. This has the effect that when the magnifying glass body is swiveled in, the U-legs with their insides apply a relatively strong pressure to the surface of the lens part of the magnifier body, which despite the dimensionally stable, the contour shape of the magnifier body adapted training of the U-legs and despite their velvety coating on the inside of which leads to the scratching of the surface of the lens part of the magnifier body.

The solution to the aforementioned problem is the subject of the label of claim 1. The U-legs of the case are spread apart somewhat in the fastening area by the spacer parts. Because of the dimensionally stable design of their insides, the inner surfaces of the U-legs come from here out of contact with the surface of at least the lens portion of the magnifier body. In any case, however, the contact pressure

the inside of the U-legs of the case against the lens part the magnifying glass body is significantly reduced by this spreading apart. If the lens part is only one-sided Has convex design, it may be sufficient if the spacer is arranged only on the convex side.

In a particularly simple way, the invention can be Realize the effect through the feature of claim 2. For the production of the spacer parts are then no separate Components required. Only the magnifying glass body or its boom need to be designed accordingly, which is the case with one Molded part poses no difficulties.

The subject matter of the invention is described in more detail with reference to the figures. Show it:

Sheath 2 has approximately the dimensions of the magnifying glass body 1, so that in the swiveled-in position the top surfaces of the magnifying glass body 1 are covered by the top surfaces of the case 2. The sheath 2 has an essentially U-shaped cross section on. The two top surfaces of the case 2 are formed by the U-legs 3, 4. Between the free U-leg ends 5, 6 in the area of the corner edge 7 of the case 2, the magnifying glass body 1 is eccentric in its side area 8 attached. For this purpose, the magnifying glass body 1 is provided with a through-bearing hole running perpendicular to its central longitudinal plane 9 10 provided. A tubular rivet 11 engages with its shaft through the bearing hole 10. The longitudinal axis 12 of the The tubular rivet runs perpendicular to the central longitudinal plane 9 of the magnifying glass body 1 or the case 2 or its U-legs 3, 4.

The U-legs 3, 4 of the case 2 are made of a dimensionally stable material, e.g. an impregnated cardboard or a Plastic injection molded part. As a rule, the U-legs 3, 4 are made in one piece from these materials by they are connected to one another by the yoke 13. Through the rivet heads 14,15, the leg ends are 5,6 on both sides pressed against the top surfaces of the side area 8 of the magnifier body 1. The inner surfaces 16,17 of the U-legs 3,4 are provided with a velvet cover 18, which e.g. Flocking is made. The inner surfaces 16,17 of the U-legs 3, 4 have a cross-sectional shape corresponding to the surface shape of the magnifying glass body 1.

The magnifying glass body 1 is injection-molded in one piece from plastic. Its lens part 19 has a convex curvature on both sides on. The lens part 19 has a circular outline shape. It is surrounded in its central longitudinal plane by an approximately square edge part 20 with approximately plane-parallel surfaces 21 and a substantially reduced cross-sectional thickness 23 compared to the maximum cross-sectional thickness 22 of the magnifying glass body 1. The bearing hole 10 is located in the side area 8 of the edge part 20.

The two-sided mouths of the bearing hole 10 are circularly surrounded by spacers 24,25, which are integral to the Edge part 20 is integrally formed. The spacers are in the direction of the longitudinal axis 20 on both sides over the surfaces 21 of the Edge part 20 and rest with their front ends on the leg ends 5, 6 of the case 2. You spread the U-legs 3, 4 of the sheath 2 slightly apart against the pressure of the rivet heads 14, 15 and thus generate the intended invention Effect.

The sheath 2 can be covered with a cover 26, for example made of leather be concealed. Between the cover 26 and the Ü-thighs 3, 4 or their yoke 13 can be sandwiched by a soft foam layer 28 laminated onto cardboard 27.

When it is said that the U-legs 3.4 from a

consist of dimensionally stable material, it need not be called that the thighs are inherently stiff. Rather, the U-legs have a certain elastic deformability permissible.

The idea on which the invention is based can also be implemented in the same way with double swiveling loupes, in which, for example, two magnifying glass bodies 1 can be pivoted in the direction of the longitudinal axis 12 one above the other around the same longitudinal axis 12 are arranged. Here it would be important that the spacer parts 24, 25 each on the sides facing away from one another the magnifier body 1 are arranged.
