DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement of or in a luminous dot sighting instrument suitable for use in connection with a telescopic attachment. More particularly, the invention comprises means for vertical and horizontal adjustment of a luminous dot sighting instrument in relation to a support for connecting the luminous dot sighting instrument with a firearm, means for detachably connecting said luminous dot sighting instrument with said telescopic attachment, and a device for accurately presetting and centering the position of the luminous dot in relation to the telescopic attachment, without interfering with the centered position thereof when the telescopic attachment is removed from and again mounted on the luminous dot sighting instrument.
The use of telescopic attachments with luminous dot sighting instruments is of recent occurrence. The manner in which the telescopic attachment is connected with the luminous dot sighting instrument may vary, but since telescopic attachments sometimes are a hindrance to rapid aiming and shooting, or on certain occasions perhaps even may be unnecessary, the connection should permit simple mounting and removal of the telescopic attachment.
An objective common to both luminous dot sights and telescopic sights which are to be used separately as a sighting instrument and therefore are mounted directly on a firearm, is that the sight, after it has been detached from the firearm, should be reattachable thereto in such an exact position that the firearm need not be test-fired again. Also, these separately used sights should permit simple and exact vertical and horizontal adjustment during test-firing.
A closely related objective in a luminous dot sighting instrument with telescopic attachment is to make the attachment readily adjustable in relation to the luminous dot sighting instrument, such that the luminous dot, i.e. the aiming point, will be correctly centered with respect to the telescopic attachment.
In luminous dot sighting instruments where the vertical and horizontal adjustments are carried out by moving an inner tube containing an optical system with a light source and at least one semitransparent mirror, and preferably also the main lens of the lens system, in relation to an outer tube of the luminous dot sighting instrument, certain problems are encountered which are both functional and economical. The functional problem is that the viewing field is changed in response to the angle of adjustment of the inner tube in relation to the outer tube, and this may limit the maximum adjustment that can be attained. The economic disadvantage is that one may have to use a lens system having an unnecessarily large diameter in relation to the diameter of the inner tube to bring about the required angular adjustability in the outer tube. The economically most favourable solution, which is to grind the outer circumferential edge of the main lens to form the surface of a cylinder coaxial with an axis extending through the centre of the lens and at right angles to the lens plane, could not be used when the lens plane was positioned obliquely in relation to the longitudinal centre axis of the inner tube.
It is an object of the present invention to obviate these problems.
Admittedly, the problems discussed above are independent of one another in so far as the solution to one problem is applicable independently of the solution to another of these problems, but when the solutions are used concurrently, they are to some extent interrelated, for example, because the telescopic attachment makes the sighting instrument much longer.
To sum up, the invention serves to provide a luminous dot sighting instrument with vertical and horizontal adjustment means which permit a less problematic adjustment and are of a lighter and more economic, compact construction than conventional vertical and horizontal adjustment means for luminous dot sighting instruments and which also widen the possibilities of positioning the luminous dot sighting instrument optionally in relation to a firearm,
