DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(12) The preferred embodiment of the adaptor device in FIG. 1 having a main body 10, and a plurality of protrusions 18. The optical device 13 shown is binoculars, wherein the adaptor device is aligned with the binoculars' first optical axis, or if in the case of a monocular, the sole optical axis. The device is depicted in a coupled state to an electronic device comprising a camera 12. In this example shown, the electronic device having a camera 12 is a smartphone attached via physical, mechanical, magnetic, or a combination thereof means to the adaptor device. For example, the main body could include an array of magnets that mates with a matching set of magnets that are part of the electronic device. However, the adaptor device may also be coupleable to the electronic device indirectly by utilizing additional components, such as a holder or case for the electronic device. In the embodiment shown in FIG. 2, the holder is a plastic sleeve 14 maintaining a grip around a rubber case 15 that encases the electronic device.

(13) In another preferred embodiment of the adaptor device, the adaptor device also having a main body 10 and a plurality of protrusions 18 is shown with different instance of optical device 13 and electronic device comprising a camera 12 in FIG. 3. In this embodiment, the optical device is a microscope, specifically a biological microscope with a binocular eyepiece, wherein the adaptor is aligned with the first optical axis. This example can also apply to a monocular eyepiece microscope, where the first optical axis would be the sole optical axis. In this case, the electronic device comprising a camera 12 is a tablet. For this specific application, the diameter of the adaptor device can be adjusted for the smaller eyepieces typical of microscopes. Also, for a heavier electronic devices such as a large tablet, reinforcing members or additional supports can be added to balance the weight of device while keeping the electronic device stable and secured. Once again, the electronic device can be coupleable directly as in FIG. 3 or indirectly as in FIG. 4 by use of additional components, such as a holder 14 and case 12.

(14) The adaptor device is shown without an optical or electronic device in FIG. 5a, which depicts the preferred embodiment with a main body 10 with an opening 20 in the bottom surface and a plurality of protrusions. In FIG. 5a, each protrusion 18 has only a first member, such as a solid resilient plastic, which is ideally a thin walled structure so that the protrusions may act as a flexure to conform to a range of diameters. The protrusions must be placed around a common center to ensure the device is self-centering with a range of diameters of optical devices. Also, the thickness and stiffness of the material must be balanced so as to provide a secure hold on the optical device yet able to bend to accommodate a range of diameters. Ideal thicknesses range from 0.75 mm to 1.75 mm for a typical ABS plastic material, depending on requirement for the range of diameters.

(15) Another preferred embodiment shown in FIG. 5b depicts the protrusions can also include a frictional segment 11, which can serve several purposes. First, the frictional segments can provide additional hold with the housing of the optical device, especially when the optical housing is made of a smooth material, such as metal or plastic. Second, the frictional segments can also be of a flexible material that provides an additional conforming effect around different contours of the optical housing. Third, it can help extend the range of diameters the device is capable of coupling with, as these frictional segments if made from a flexible material, could compress radially to accept larger diameter optical devices, while still maintaining enough hold to grip onto smaller diameter optical devices. The frictional segments may be a portion of rubber paint, a rough foam, rough fabric or rubber portions, which may be permanently affixed or removeably connected to the first member. One benefit of having removable frictional segments is that it may be advantageous for the user to use both the first member independently and with the frictional segments, to even more substantially extend the range of diameters of the optical device that are coupleable to the adaptor.

(16) In another preferred embodiment in FIG. 6, the frictional segments 11 of the plurality of protrusions can form a single ring of frictional segments. Furthermore, this single ring is flexible so as to not constrict the radial conforming of the adaptor device to fit around multiple diameters of optical devices. The flexible ring is ideally made from an elastomeric material, such as silicone rubber, that can conform and stretch to meet a range of sizes and shapes. This ring is also a more convenient form of the frictional segments as the user can removeably connect a single frictional element to the adaptor device, so that for a very large range of diameters of optical devices, the user may utilize a few differently sized rings and switch out the ring for the specific device. In this case, only approximately three to five rings would be necessary to account for all existing optical products. The frictional segments can also be combined into a series of nested rings as shown in FIG. 8, for storage of the various sized rings, or for direct use. For example, with three nested rings, with use on a small diameter, all three rings can be left in place and used to connect to the optical device, while on a larger diameter, one or more rings can be removed and then the remaining rings in combination with the adaptor device can be used to connect to the optical device.

(17) The flexible ring can also be externally shaped to conform to the protrusions as shown in FIG. 7, where for example there are additional ridges 17 extending outward in a radial direction. The benefit of these additional ridges is that when twisting the adaptor device around the optical device during the coupling, de-coupling or adjustment of orientation steps, the frictional segments 11 will stay in place relative to the main body 10. This is helpful if the user wishes to place their electronic device at a certain angle relative to the optical device, such as a horizontal or vertical orientation. Another additional feature shown in FIG. 7 is a flange 19 on the plurality of protrusions with a mating cutout 16 on the flexible ring. The benefit of these additional features is that during removal of the adaptor device from the optical device, the frictional segment may stay gripped onto the optical device, such that only part of the device is removed, thereby requiring two removal steps. These mating portions eliminate any possibility of having two removal steps, since these features retain the flexible ring within the flanges, so that the two components will always be removed together as a single unit. The flange 19 may also be use independently in the embodiment with only the first member, as it could help to snap onto a rim of an eyepiece. Additionally, all of the aforementioned features, namely the additional ridges 17 and the flange 19 with mating cutouts 16, can also eliminate the need for adhesive or other fasteners to join the frictional segments 11 to the other parts of the adaptor device. As a result, this also allows the user to easily switch out differently sized rings, in thickness and diameter, for their specific range of optical devices.

(18) Also, the bottom surface of the main body 10 is ideally shaped to connect the adaptor device to the electronic device, such as in the case of a snap-fit connection between the adaptor device and a holder for the electronic device. For example, an cylindrical protrusion can be designed to snap-fit into a cylindrical cutout in the bottom surface of the main body. In one preferred embodiment as shown in FIG. 9, the cutout in the bottom surface of the main body is a cylindrical cutout 20 that mates to a cylindrical protrusion 21 in a case or holder for the electronic device. The use of a snap-fit connection could be advantageous to the user with multiple devices, who has a holder for each type of device with the same cylindrical protrusions. Then the user can mix and match the electronic devices with the optical devices with use of this adaptor device.

(19) It can thus be seen that the present invention is advantageous and overcomes the perceived deficiencies in the prior art.

(20) It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above constructions without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
