Priority is claimed of German Patent Application No. DE102020113533.5, filed May 19, 2020, and entitled “Light Dot Sight”, the disclosure of which is incorporated by reference herein in its entirety as if set forth at length.
The invention relates to a light dot sight which can be affixed to the surface of a breech of a firearm with a partially transparent reflector element that reflects the parallel light of a light source attached to the firearm and focused on the retina of a shooter into the eye of the shooter.
Light dot sights of the type mentioned above are used in the prior art as target devices, in particular for handguns. The known light dot sights, however, have the disadvantage that the reflector element is inserted into a usually metallic socket, by means of which the reflector element is anchored at least indirectly in the surface of the breech.
The metallic socket has the disadvantage that important areas in the field of view of a shooter are obscured by the socket in such a mounting, so that the shooter cannot fully perceive an event taking place around him.
The object of the invention is therefore to create a light dot sight which never restricts the field of view of a shooter directed to a particular event.
For a light dot sight of the above mentioned type, this object is achieved according to the invention in that the undersurface of the partially transparent reflector element has a width which is dimensioned for anchoring the reflector element directly and robustly in the region of the surface of the breech by means of a fastener.
Preferred embodiments of the invention are the subject matter of the subordinate claims, the elements of which act in the sense of a further improvement of the approach to achieving the object underlying the invention.
With the light dot sight according to the invention, by means of the combination of features that the undersurface of the partially transparent reflector element has a width which is dimensioned for anchoring the reflector element robustly in the region of the surface of the breech by means of a fastener, a device is created by means of which a completely unobstructed view of an observed event is enabled for a shooter with his weapon aimed.
According to a first preferred embodiment of the light dot sight according to the invention, it is provided that the width of the partially transparent reflector element in the region of the undersurface close to the breech is larger than the width of the optically effective area of the partially transparent reflector element remote from the breech.
As an alternative to the above embodiment, the width of the partially transparent reflector element in the region of the undersurface close to the breech may have the same dimensions as the optically effective area of the partially transparent reflector element remote from the breech, wherein due to the total thickness of the reflector element the undersurface of the partially transparent reflector element then has a width which is sufficiently dimensioned for anchoring the reflector element robustly by means of a fastener.
The reflector element is traditionally formed by a plane parallel plate provided with a partially reflective surface or by a concave/convex lens provided with a partially reflective rear surface. In the latter case, the concave rear surface of the concave/convex lens acts like a hollow mirror as a collimator for the divergent light of the light source.
Preferably, an adhesive is provided as a fastener. Alternatively, the fastener may be formed by one or more screws that are guided at a predetermined angle through the reflector element and anchored in the region of the surface of the breech.
Between the light source and the reflector element, a collimator in the form of a collection lens, which transfers the light of the light source usually formed by an LED into a parallel beam of light, may preferably be arranged in the immediate vicinity of the light source, wherein the light source and the collimator are combined into a robust unit, which is anchored in the surface of the breech in front of the reflector element by means of one or more screws as anchoring elements or by means of an adhesive.
According to an important preferred embodiment of the light dot sight according to the invention, the light source, the collimator in the form of a lens and the reflector element are combined into a robust unit, which is anchored by means of one or more anchoring elements such as screws or adhesive in the region of the surface of the breech.
The light dot sight according to the invention is explained below on the basis of a preferred embodiment, which is shown in the figures of the drawing. In the figures:
The light dot sights 100 according to the invention shown in
The undersurface 111 of the partially transparent reflector element 110 has a width which is dimensioned for anchoring the reflector element 110 robustly in the region of the surface of the breech 200 by means of a fastener.
The width of the undersurface 111 of the partially transparent reflector element 110 is dimensioned for anchoring the socketless reflector element 110 robustly in the region of the surface of the breech 200 by means of a fastener acting directly on the reflector element 110.
According to the embodiment of the present invention shown in
The reflector element 110 is formed by a concave/convex lens provided with a partially reflective rear surface, wherein the concave rear surface of the concave/convex lens acts similarly to a collecting lens as a collimator 130 for the divergent light of the light source 120.
According to the embodiment of the present invention shown in
The embodiment of the invention explained above is used only for the purpose of a better understanding of the teaching according to the invention specified by the claims, which as such is not restricted by the exemplary embodiment.
