Abstract
For drilling fixing holes in the edge of a spectacle lens 3 the latter is clamped between projections 5 and 15 on a body 1 which can be gripped in zone 17. Clamping is effected by a screw 2 which has a drill guide 4 extending along its axis. An opening 6 receives the end of the drill after passage through the lens. In an alternative construction a drill bush takes the place of the opening 6 to allow drilling from both sides. <IMAGE>
Description
SPECIFICATION
Drilling gauge
The invention relates to a drilling gauge for producing fixing holes in the rims of spectacle lenses.
Rimless spectacles which are provided with the so-called four-hole or eight-hole metal fittings to fit the bridge-piece for the nose and the side pieces to the lenses are well known. Hitherto the necessary holes in the rims of the lenses have usually been made without the help of drill guides which in practice placed high standards on the skill and accuracy of workmanship of personnel carrying out the work and did not always lead to reliable and satisfactory results.
The invention therefore has as basis the problem of devising an easy-to-operate drill gauge for the optical workshop which enables holes to be placed precisely in the rims of spectacle lenses.
In accordance with the invention this problem is solved by means of a drilling gauge containing a reception zone with abutments for locating the edge of the lens and has projections overlapping the spectacle lens edges in a U-formation, the projection nearest the drill having a clamping device with a drill guide.
Advantageous further developments of the drilling gauge in accordance with the invention are described in the subsidiary claims.
In the projection which engages the surface of the lens an additional drilling bush can be arranged in such a way that the glass can be drilled from both sides in order to achieve perfect edges to the holes.
The projections which grip round the rim of the lens can have on an outer face markings aligned with the drill guide in order to achieve an exact alignment of the drilling gauge relative to the marking on the glass and the direction of the drilling axis.
The main body can have discontinuities in the supporting surface and so guarantee a precise support.
In the drawing two embodiments of the invention are shown.
In the drawing
Figure 7 is a side view of a drilling gauge
Figure 2 is a further example of an embodiment of a drilling gauge in side elevation and
Figure 3 is a plan view of Figure 2 along section
A-B.
Figure 1 shows a partially cut-away side view of a first embodiment of a drilling gauge in accordance with the invention. The drilling gauge has a main
body 1 with two projections 5 and 15 which overlap the edge of a spectacle lens 3 to be drilled in a
U-formation. A clamping screw 2 is screwed into the projection 15 and a drill guide 4 is provided which extends along the axis of the clamping screw 2.
In the projection 5, aligned with the axis of the drill guide 4, there is a through opening 6 which prevents damage to the drilling gauge by a drill which has
passed through the lens 3.
At the sides of the main body 1 there are gripping
recesses 17 (see also Figure 3) with a surface configuration which facilitates gripping.
Figure 2 shows a further embodiment of the drilling gauge in accordance with the invention. This gauge also has a main body 7 within two projections 11 and 21. As in the embodiment of Figure 1 a clamping screw 8 is screwed into the projection 21 and clamps a spectacle lens 10 which is to be drilled.
Along the axis of the clamping screw 8 there is a drill guide 9 for a drill which is not shown. Aligned with the drill guide 9 a drill bush 12 is provided in the projection 11. By this means it is possible to drill the lens from both sides, so that satisfactory edges can be produced on the drill holes.
In contrast to the embodiment shown in Figure 1, in the embodiment shown in Figure 2 the working surfaces of the rectangular main body 7 are not flat but have a recess or through opening 18. This recess 18 makes it possible, if for example there are cuttings on the table of a drilling machine (not shown), to set the drilling gauge up without damge by these cuttings, since the cuttings can find a place in the recess. Furthermore material is saved by means of the recess 18 when, for example, the drilling gauge is produced as an injection moulded part.
Figure 3 shows a section on the line A-B of the drilling gauge shown in Figure 2. The gripping depressions 17 provided at the sides of the main body 7 are clearly seen. It is further shown that the spectacle lens clamped by the screw 8 lies with its edge against abutment 13 and 14 on the main body 7.
The projection 21 has a marking 22 which facilitates positioning of the drill holes with respect to markers provided on the spectacle lens.
1. A drilling gauge for producing fixing holes in the edge zones of spectacle lens characterized in that the gauge has a reception zone with abutments for locating the edge of the lens and has projections overlapping the spectacle lens edges in a Uformation, the projection nearest the drill having a clamping device with a drill guide.
2. A drilling gauge as claimed in claim 1 in which the clamping device is a clamping screw and the drill guide extends along the axis of the screw.
3. A drilling gauge as claimed in claim 2 in which the clamping screw is made of plastics material and the drill guide is a metallic drilling bush.
4. A drilling gauge as claimed in any of the preceding claims in which the projection which engages the lens surface has a hole aligned with the axis of the drill guide.
5. A drilling gauge as claimed in any of claims 1 to 3 in which in the projection which engages the lens surface a drilling bush is arranged in alignment with the axis of the drill guide.
6. A drilling gauge as claimed in any of the preceding claims in which on at least one of the projections a surface marking is provided in alignment with the drill guide.
7. A drilling gauge as claimed in any of the preceding claims in which the reception zoneforthe lens is attached to a gripping part.
**WARNING** end of DESC field may overlap start of CLMS **.
