Abstract
In an eyepiece cup for binoculars, which fits substantially tightly in particular around a user's eyes, provision is made for air admission holes.
Description
- 1. Field of the Invention
- The invention relates to an in particular ergonomically shaped eyepiece cup for binoculars.
- 2. Background Art
- Eyepiece cups of the generic type have a human face contact area matched to the shape of the head in the vicinity of the eyes so that as close as possible a contact is attained, preventing scattered or extraneous light that might interfere with observation from entering. A close contact of this type, advantageous per se, is accompanied with the undesired side effect that the space between the eyepiece cup, the eye and the eyepiece is closed outwardly almost hermetically, there being the risk of fogging of the eyepiece lens.
- It is an object of the invention to embody an ergonomically shaped eyepiece cup such that this fogging is largely prevented.
- According to the invention this object is attained by air admission holes being formed on the eyepiece cup for ventilation of the interior.
- Preferably it is provided that the air admission holes are distributed around the eyepiece cup at a distance from each other in the area above the eyepiece, the air current that enters through the air admission holes being deviated. In this way it is attained that no light can penetrate through the air admission holes and that the admitted air does not hit the eye of the user.
- By advantage it can be provided that the admitted air current is deviated onto the inside of the eyepiece lens so that the lens is reliably kept non-fogging and the air current is guided away from the user's eye.
- For optimal contact of the eyepiece cup with the user's face to be ensured in spite of adjustment of the eyepiece, the eyepiece cup may be pivotal relative to the eyepiece.
- If binoculars with eyepiece cups according to the invention are used in the open air, the available blast will as a rule be sufficient to produce a satisfactory air current.
- As compared to this, controlled ventilation may be provided in order to meet the requirements in very humid regions or in closed rooms as for example in watchtowers.
- Such a controlled ventilation can be put into practice by a sort of a fan or by pumping action caused by the intrinsic elasticity of the eyepiece cups.
- Details of the invention will become apparent from the ensuing description of a preferred embodiment, taken in conjunction with the drawing.
- FIG. 1 is a side view of an eyepiece cup according to the invention; and
- FIG. 2 is a sectional view, broken open, of the eyepiece cup of FIG. 1.
- An eyepiece cup 1 seen in the drawing consists of a comparatively soft rubber material, the
contact area 2 having a configuration which matches with the shape around the human eye. Eyepiece cups 1 of this type are conventionally provided on each of the twoeyepieces 3 of binoculars. - The way in which the eyepiece cup 1 is mounted on the
eyepiece 3 can be seen in particular in FIG. 2. A clamping ring 4 adjoins the eyepiece cup 1 with acatch 5 and a threadedring 6 being provided within this clamping ring 4. Aneyepiece lens 9 is disposed on an eyepiece mounting 7 by way of an O-ring 8. - A plurality of
air admission holes 10 are disposed at a distance from each other at the foot of the clamping ring 4 above theeyepiece 3. - Air is admitted from outside through the
air admission holes 10, then deviated via achannel 11 vertically upwards in the drawing, moving from thischannel 11 into an area below an inwardannular collar 12 of the eyepiece cup 1 and from there in the direction of the arrow 13 onto theeyepiece lens 9 so that the lens is kept non-fogging. This deviation prevents the air current from directly hitting the eye, there being no draught that might negatively affect the eye. - In order for the
contact area 2 of the eyepiece cup 1 always to fit correctly on the user's face regardless of the adjustment of theeyepiece 3, the eyepiece cup 1 is pivotal relative to theeyepiece 3.
