Definitions
- the invention relates to a template for a spectacle lens with at least one hole or a marking.
- Templates for spectacle lenses are used, among other things, to determine the locations at which the spectacle lens is to be drilled, or to determine the position at which a fitting or frame part on the spectacle lens, e.g. to be attached by gluing. With a template, however, markings can also be made on a lens. Templates are also particularly necessary when it is necessary to attach eyeglass temples (cheeks) or nose bridges for rimless glasses to the glasses lenses.
- German Offenlegungsschrift 44 38 634 is a template by which the location at which a hole is to be drilled in an eyeglass lens can be determined.
- This template can be a transparent film that can be placed on the lens via an adhesive surface.
- the adhesive effect is designed in such a way that on the one hand slipping of the film relative to the glass during the processing operations is impossible, but on the other hand the film can be easily detached from the glass even after processing.
- This type of stencil is difficult to handle, since the application of a flat adhesive film on a curved lens surface usually does not work straight away. Since the film adheres, it cannot be moved or rotated in relation to the glass. Rather, it must be completely removed from the glass.
- a film is not very suitable as a drilling template: On the one hand, it is difficult to drill holes that are to be exactly spaced from one another. On the other hand, it is problematic to drill a hole in the glass so that the axis of the hole forms a desired angle with the surrounding glass surface.
- German utility model 93 04 045 it is known to also use a shaped disc for grinding in spectacle lenses as a drilling jig. turn. For this there are holes in the shaped disc. A form disk is placed on the lens for drilling. The holes in the form disc are used as a guide for a drill.
- the shaped disc is a rigid, flat disc. In order to be able to drill properly, it is necessary to use a plate with pins to hold a shaped washer and with additional eccentric stops. As a result, the spectacle lens and the shaped lens can be adjusted one above the other, but the handling of this template is very complex. Glass and molded disc are connected to each other with an adhesive pad.
- the invention has for its object to provide a template of the type mentioned, which is easy to use and which still allows markings to be quickly and economically attached to spectacle lenses or to determine locations for the fastening of frame and fitting parts or for bores .
- the template with a blocker placed on the lens is non-displaceable and non-rotatably connected relative to it, so that the position of the hole or the marking is fixed relative to the lens.
- the invention is based on the finding that a blocker is extremely suitable for interacting with a suitable template and for achieving the object according to the invention:
- One of the tasks of an optician is to adapt the lens blanks, which are usually supplied by the manufacturer with a circular peripheral contour, to the shape specified by an eyeglass frame or - in the case of rimless glasses - to the desired shape. Molding can be done in a glass edge processing machine.
- a so-called blocker (also known as a mounting block) and a coaxial counter bearing, both of which hold the blank in its central area, are used to attach the lens blanks to a rotating shaft of the machine.
- Blockers can be designed as suction blockers or as adhesive blockers. The purpose and function of a blocker are explained for example in DE 43 00 673 AI.
- the template provided is connected to a blocker placed on the spectacle lens in such a way that the template is rotationally fixed relative to the blocker. Since the blocker is in turn fixed and non-rotatably attached to the lens (see DE 43 00 673 AI, column 1, lines 13 and 14), the template is also non-rotatable relative to the lens.
- connection can be designed so that it is easily detachable.
- the marking or the hole of the template is located over the position of the lens that has to be marked or where a hole is to be drilled or a fitting part is to be positioned.
- Such a template is easy to use. It can be quickly placed on the lens and removed. Because of these properties and the possibility of being able to reuse the template frequently, the proposed template is very economical.
- edge of the blank supplied by the eyeglass lens manufacturer must in any case be brought into the specified or desired shape of an eyeglass lens, it is also necessary to place a blocker on the eyeglass lens blank.
- this means that the placement of a blocker is not an additional work process. It is not necessary to first process the edge of the lens blank and then to apply the markings or to determine the location of a hole or a fitting part to be fastened. Rather, it is also possible to carry out this activity before the edge processing.
- bore also includes openings in the spectacle lens other than only rotationally symmetrical openings. According to the invention, this term also includes slit-shaped openings or, for example, millings or bores in the edge region of an edge-processed spectacle lens.
- the proposed template is particularly advantageous when two holes are to be drilled in a spectacle lens, which holes must be at a fixed distance from one another. This is necessary, for example, when a bracket or a bridge is attached to the lenses of rimless glasses in a rotationally fixed manner.
- the proposed template can also be used without a blocker connected to the spectacle lens. This is necessary if, for example, a customer wants an individual lens shape.
- the glass can first be blocked and the outer shape of the glass can be ground individually. The blocker is then removed, the template is positioned using markings and the glass is held together with the template in the drilling area. Now you can drill the glass and then assemble it.
- a preferred embodiment of the invention is given according to subclaim 2 if the drilling template has a shape associated with the shape of the blocker for a spectacle lens in a partial area.
- the template has a shape in a partial area, due to which it surrounds the blocker in such a way that its constant contact is ensured. Since almost all blocker heads have the same shape, it is not necessary to stock a large number of templates that are adapted to different blocker head shapes.
- a typical blocker head shape is shown, for example, in FIG. 2 of German utility model 92 00 513.
- at least the area of the template adjoining the partial area consists of elastically deformable material. In this way, the drilling template can be easily adapted to different shapes of the lens surface.
- the template can be used with spherical and aspherical lenses, with plus or minus lenses and with lenses with different radii of curvature
- Glass surfaces are used. By applying little pressure to the central area or the edge area of the template, it can be adapted to different surfaces.
- a template according to the invention is particularly simple and inexpensive to manufacture if, in the preferred embodiment according to subclaim 4, it is an injection molded part.
- the template is designed as a drilling template.
- a metal drill guide is attached to the template.
- the metal drill guide has a circular cylindrical opening into which a drill with a suitable diameter can be inserted. Thanks to the Bolner guide, the location of the hole can be precisely determined and the hole can be easily drilled.
- the drill guide can be attached to the template in a variety of ways.
- the drill guide is fastened in the template by gluing, pressing in, fitting in or by clip fastening.
- the longitudinal axis of the drill guide can enclose a defined, in particular a right angle, with the template surface surrounding it.
- the template is made of elastic material at least in its outer area, it can - as already explained - be deformed in such a way that it rests on the surface of the spectacle lens. In this way, it is possible to produce bores in which the axis of the borehole with the spectacle lens surface forms the same angle as the longitudinal axis of the drill guide with the template surface surrounding it.
- the template can advantageously be adapted to a given spectacle lens surface by simply pressing on the area in which it can be connected to the blocker.
- Fig.1 A section through a template according to the invention with drill guides.
- FIG. 2 An enlargement of that shown in dashed lines in Fig. 1
- Fig.3 A top view of the template according to Fig.1. characters
- 4a and 4b a front and a side view of a blocker.
- Fig. 5 One plus and one minus glass as well as a blocker glued onto a plus glass.
- Fig. 6 A template that is connected to a blocker, which in turn is attached to the lens.
- Fig. 7 A section perpendicular to the section shown in Fig. 6 through the area of the blocker.
- 8a and 8b top views of templates for right and left glasses.
- Fig. 11 A drill guide that is attached to the template by a clip attachment.
- the template 1 shown in the figures is an injection molded part.
- the template 1 has a shape assigned to the shape of a blocker 5 for a spectacle lens 4.
- a blocker 5 is shown in Figures 4a and 4b. 4a shows that there is a groove 7 in the blocker head 11.
- An adhesive pad 6 is glued to the underside of the lower part 10 of the blocker 5.
- the blocker head 11 has a screw head shape.
- the central portion 12 of the template 1 is designed as a negative receiving part for the blocker head 11.
- a web 8 in this part is used for correct insertion.
- the area 13 of the template 1 surrounding the receiving part 12 also consists of elastically deformable material.
- two metal drill guides 2 are fastened.
- the openings can have different diameters.
- the blocker 5 Before the edge processing of an eyeglass lens 4, the blocker 5 is placed on the eyeglass lens 4 in a centering device, in which the eyeglass lens blank 4 can be aligned according to the decentration values, the axis position and / or the position of a close-up part, and connected, for example by gluing.
- the blocker 5 glued onto the lens blank 4 can now be inserted in a corresponding negative receiving part on the shaft of the edge processing machine.
- the template according to the invention can be placed on the lens blank 4 with the blocker 5 glued on. It is irrelevant whether the edge of the blank is first machined and then the spectacle lens is drilled, or whether the blank is first drilled and then the edge is machined.
- the template 1 is connected to the blocker 5 in a rotationally fixed and immovable manner due to its shape assigned to the blocker 5.
- the blocker 5 is in turn non-rotatably and immovably connected to the spectacle lens (blank) 4.
- the position of the bolt guides 2 and the drill axes is precisely defined. It is now easily possible to drill the holes 9 provided in the spectacle lens 4 by inserting a suitable drill 3 into an opening 14 in the drill guide 2 and drilling the required hole.
- the area 13 of the template 1 surrounding the receiving part 12 can be flat. Due to the elastic properties, it is possible to apply the template to the lens surface by applying slight pressure either to the receiving part 12 or to the surrounding area 13.
- the area 13 surrounding the receiving part 12 is spherical. If the spherical radius of the spherical template area 13 is smaller than the radius of curvature of the surface of the spectacle lens 4, the template can be brought into contact with the spectacle lens surface by pressing the receiving part 12 onto the spectacle lens.
- the drill guides are fastened in the template 1, for example by gluing, pressing or fitting.
- the longitudinal axes of the openings 14 in the drill guide 2 form a defined angle with the surrounding surface, which is 90 ° in the exemplary embodiment. Of course, other angles can also be selected.
- the template 1 which consists of transparent material in the exemplary embodiment, bears a marking 15 which shows the shape of the peripheral contour of an edge-processed spectacle lens.
- FIG. 1 A variant of the bolir guide 2 is shown in FIG.
- the bolir guide 2 is made of metal.
