[0053] Way(s) of Embodying the Invention
[0054] Exemplary embodiments (slightly differing from one another to some extent) of a smartphone stereoscope of the invention are depicted in the figures, in part in an arrangement on the underside of a baseball cap visor. The illustrations shown are not in any way high precision design drawings, but rather schematic sketches depicting the essential components and elements The elements that are the same from figure to figure are designated with the same reference numerals.
[0055] A first exemplary embodiment of a smartphone stereoscope of the invention is depicted and generally designated with the reference numeral 1 in FIGS. 1 through 7. The smartphone stereoscope 1 has a base 2, on which a support bar 3 is formed. This support bar 3 serves as a support for a longitudinal edge of a smartphone intended to be secured to the smartphone stereoscope 1 In particular it can be integrally formed with the base 2, which in particular is made of a plastic material. A bridge 4 that also serves as a support for a longitudinal edge of a smartphone is formed parallel to the support bar 3 and likewise integrally with the base.
[0056] In the unfolded state of the smartphone stereoscope 1 depicted in FIG. 1, a partition 5 is in an essentially 90 degree orientation to the plate-like base 2 and to the longitudinal direction of the support bar 3. The partition 5 is pivotally mounted on the base 2 and can be pivoted about a pivot axis that runs in the plane of the base 2 and essentially perpendicular to the longitudinal direction of the support bar 3 so that in the folded state, the plane of the plate-like partition 5 coincides with the plane of the base 2. This will be described in more detail further below.
[0057] A lens holder 6 is also pivotally mounted on the base 2. This lens holder 6 is also essentially plate-like in configuration and, in the unfolded state shown in FIG. 1, is oriented with its extension plane running at a right angle to the extension plane of the base 2 as well as to the extension plane of the partition 5. Accordingly, the respective planar orientations of the three plate-like elements base 2, partition 5, and lens holder 6 run in three linearly independent, mutually perpendicular spatial directions.
[0058] In the design shown, two lens receptacles 7 are arranged on the lens holder 6 in such a way that they can pivot relative to the latter for adjustment to the eye separation distance of a user. However, the lens receptacles 7 can just as easily be rigidly fixed, in particular also integrally formed, on the lens holder 6 with no possibility of adjusting their distance. A magnifying lens 8 is mounted in each lens receptacle 7. As FIG. 1 clearly shows, in their portions depicted in the figure in the lower area in each case, the lens receptacles 7 are open, encompass the circumference of a circular lens receptacle opening with channel-like holders having only partially circular segments with an aperture angle somewhat greater than 180° in each case, here ca. 190°. The magnifying lenses 8 may thus be easily introduced and mounted in the lens receptacles 7, specifically by inserting them from the open side until they lock or click into place in the lens receptacles 7. Like the other elements of the smartphone stereoscope 1, the lens receptacles 7 are also preferably made of a plastic material. In particular, the magnifying lenses 8 are likewise made of plastic and preferably implemented as Fresnel lenses.
[0059] Starting from lateral portions of the retaining bar 3, a rubber strap 9 extends triangularly toward the end of the partition 5 opposite the support bar 3 in the unfolded state according to FIG. 1, where the rubber strap 9 comes together and is secured. This rubber strap 9 serves to hold a smartphone, which is intended to abut the support bar 3 and a front edge 15 of the partition 5.
[0060] As can be discerned in, for example, FIGS. 2 and 3, the lens receptacles 7 have meshing teeth 10 in the portions by which they are pivotally connected to the lens holder 6. In this manner the pivot position of the lens receptacles 7, and hence the distance of the magnifying lenses 8 to each other, can be adjusted by moving one of the lens receptacles 7, wherein the other lens receptacle 7 follows the adjustment in corresponding mirror-inverted fashion owing to the gear coupling thus formed.
[0061] A rear edge 11 of the partition 5 is formed with a diagonal cutout, which during use serves as an opening through which the bridge of a user's nose protrudes between the lens receptacles 7.
[0062] On the end of the partition 5 opposite the support bar 3 in the unfolded position, notches 12 can be discerned on the rear edge 11. These notches 12 are for the variable fixing of the portion of the rubber strap 9 arranged thereon, which forms the vertex of the triangle depicted in FIG. 1 described by the rubber strap 9. A means of adjusting the size for accommodating smartphones of different dimensions is thus provided. This will become clearer in the following explanations. For additionally securing the rubber strap 9, the latter is connected to a pushbutton 13, which can also be fixed in the area of the notches 12. This pushbutton 13 serves as an additional anti-drop device and prevents a smartphone inserted behind the rubber strap 9 from slipping out of the holder and falling in the event that the rubber strap 9 accidentally detaches from the partition 5. It can also be discerned here that a portion 14 of the partition 5 bears on the lens holder 6 in order to stabilize the shape thus assumed in the unfolded state This portion actually interlocks with the lens holder 6, as will be described further below, and thus forms a solid and secure connection such that the smartphone stereoscope 1 is fixed and stable in this position.
[0063] The unique feature of the smartphone stereoscope 1 of the invention is the simple construction, which is stable in the unfolded state shown in FIGS. 1 and 2 and is the reason why the smartphone stereoscope 1 of the invention can be very easily collapsed to a compact size. This is shown in FIGS. 3 through 5. In a view comparable to that of FIG. 1, FIG. 3 shows an intermediate state, for example during the collapsing of the smartphone stereoscope 1. As shown therein, the partition 5 can be pivoted and folded down in relation to the base 2. As can be discerned in FIG. 3, in this process the portion 9a of the rubber strap is stretched and tensioned. The portion 9b of the rubber strap on the other hand becomes slack. The portion 9a of the rubber strap thus forms a reset means that forces the partition 5 into the position shown in FIG. 1, in the unfolded state of the smartphone stereoscope 1.
[0064] FIG. 4 shows a state in which the partition 5 is fully folded down. Again the portion 9a of the rubber strap can be discerned, which in this position is stretched tight and thus forces the partition 5 into the position assumed in the unfolded state according to FIG. 1. In FIG. 4 it is furthermore possible to discern the portion 14 of the partition 15 [sic] again, which in the unfolded state bears on and interlocks with and is thus releasably connected to the lens holder 6. Also discernible is a backdrop 18, which is formed on the lens holder 6 and via which the portion 14 is guided into a locking position.
[0065] In FIG. 6 it can furthermore be discerned how the support bar 3 and the bridge 4 run parallel to one another and between them form a channel 16, into which a side edge of a smartphone can be inserted. The smartphone, which is pressed into the channel 16 by the rubber strap 9, is securely held in position by the support bar 3 and the bridge 4.
[0066] Lastly, a latching hook 19 formed on the lens holder 6 can be discerned. Even when the lens holder 6 is pivoted and folded onto the base 2 for collapsing, this latching hook engages behind a latching edge 20 and thus holds not only the lens holder 6 but also the partition 5 in the position assumed in the collapsed state of the smartphone stereoscope 1. This position or rather the folded state is then depicted in FIG. 5. In this position, the plate-like elements base 2, partition 5, and lens holder 6 with the lens receptacles 7 and the magnifying lenses 8 arranged thereon lie in a plane or in planes parallel to one another and stacked upon one another, thus giving rise to a flat and compact form that enables the smartphone stereoscope 1 to be carried easily and conveniently in, for example, a pocket or handbag.
[0067] The backdrop 18, which is formed on the lens holder 6, is again discernible in FIG. 5. An indexing notch 21 can furthermore be discerned thereon, in which the portion 14 of the partition 5 with the hook-like extension formed thereon engages when the lens holder 6 and the partition 5 are each brought into their positions assumed in the unfolded position of the smartphone telescope [sic] 1. This indexing notch 21 thus serves to lock the smartphone stereoscope 1 in the fully unfolded state.
[0068] Like the other designs in the illustrations that will be described in the following, the smartphone stereoscope 1 can in principle be used alone and as a hand-held device. But it is also particularly suited for connection to a baseball cap or visor cap in order to give rise to a head mounted display. In the following description and in the figures, reference is always made to a baseball cap. However, use can just as easily be made of a visor cap or other headgear with a visor (another style of peaked cap). The term “baseball cap” as used here should therefore include all comparable styles of peaked caps and headgear with visors.
[0069] FIG. 6 shows how the smartphone stereoscope 1 according to the preceding illustrations is arranged on the underside of a visor 23 [sic] of a baseball cap 23. To this end, the base 2 of the smartphone stereoscope 1 has a T-slot 24 on a top side. As can be discerned in FIG. 7, this T-slot 24 is guided over a T-track 25 and set thereon, the T-track 25 being fastened, for example screwed, onto the underside of the visor 22 of the baseball cap 23. With this constructive design, the smartphone stereoscope 1 can be releasably mounted in an expedient manner on the underside of the visor 22 of the baseball cap 23. By sliding it longitudinally along the T-track 25, the smartphone stereoscope 1 can be displaced in terms of a position on the underside of the visor 22 of the baseball cap 23, which is equivalent to being able to adjust the distance of the magnifying lenses 8 from the eyes of a user who is using the baseball cap 23 with the smartphone stereoscope 1 arranged thereon. This can be advantageous for persons who wear eyeglasses, for example, who need the magnifying lenses to be at an appropriate distance from their eyes so that they can also use the corrective eyeglasses while they are using the smartphone stereoscope 1, in other words so that the corrective eyeglasses will still fit between the eyes and the magnifying lenses 8 of the smartphone stereoscope 1.
[0070] Also discernible in FIG. 7 is a terry cloth band 30 applied to a headband of the baseball cap 23, which can absorb sweat and other moisture and which in particular also improves the wearing comfort of the baseball cap 23, specifically when the smartphone stereoscope 1 and a smartphone mounted thereon are fastened to the visor 22 of said baseball cap and exert pressure on the headband of the baseball cap with the force of their weight.
[0071] FIG. 8 schematically depicts how the smartphone stereoscope 1 is used in conjunction with the baseball cap 23 for viewing stereoscopic images that are reproduced on the display of a smartphone 26. It is shown here how the smartphone 26 is secured on the smartphone stereoscope 1 by means of the rubber straps 9. The smartphone stereoscope 1 bears with an upper longitudinal edge on the support bar 3 and is held by the bridge 4. By a lower longitudinal edge, it bears on the front edge 15 of the partition 5, in the area where the rubber strap 9 comes together. Due to the fact that the front edge 15 of the partition 5 is formed with a recess or kink oriented towards the rear edge 11 (as is particularly clear in FIG. 4), the smartphone 26 does bear fully with its delicate display side on the front edge 15, but only on two contact points on the upper and lower longitudinal edges in each case in the position shown in FIG. 8, regardless of the width of the smartphone. The smartphone 26 is positioned in front of or is arranged on the smartphone stereoscope 1 in a wide screen orientation
[0072] A side view of the situation shown in FIG. 8 is shown in FIG. 9, wherein a somewhat modified design of the smartphone stereoscope is depicted, which is designated with the reference numeral 1′. A somewhat differently designed partition 5′ can be discerned here, which is more simply shaped but functions in the same manner per se, is pivotal with respect to the base and is interlocked with the lens holder 6 in the unfolded state (cf. FIG. 9).
[0073] FIG. 10 shows the same arrangement in a frontal view, in other words from the side from which the viewer wearing the baseball cap 23 is looking at the arrangement. The magnifying lenses 8 are in front of the smartphone 26 accommodated in the smartphone stereoscope 1′, hence the viewer looks at the display of the smartphone 26 through the magnifying lenses 8. The partition 5′ is oriented parallel to the short edge side of the smartphone 26 and runs approximately in the center of the screen. The partition 5′ thus divides two individual images displayed on the left and the right of the screen, respectively, which together give rise to a stereoscopic image pair. Through the magnifying lenses 8, the viewer views the left image with the left eye and the right image with the right eye, wherein the images shown differ slightly in perspective and thus give rise to the three dimensional visual impression by being superimposed in the brain during viewing. The magnifying lenses 8 are chosen with respect to their focal lengths and their diameters so as to enable a view of the respective partial image of the screen (of the stereoscopic individual image) in which it is perceived in wide screen and magnified format. The focal lengths of the lenses can be in the range of 5-150 mm, particularly in the range of 40-60 mm. The diameters can be of the same order of magnitude; in particular use can be made of lenses with essentially identical focal lengths and diameters.
[0074] In FIG. 11 it can be discerned how the arrangement of the smartphone stereoscope 1′ on the visor 22 of the baseball cap 23 depicted in FIGS. 9 and 10 can be compactly folded together. In this state, the user of the baseball cap 23 is thus able to look past the form of the collapsed smartphone stereoscope 1′ thus minimized in terms of height and in particular held flat, for example when he is having a conversation with other people while still wearing the baseball cap 23.
[0075] FIG. 12 shows a side view of the situation that is shown in a view from below in FIG. 11. In both figures it can be discerned that in this variant, the rubber strap 9 does not stay secured to the partition 5′ as said partition 5′ is folded over. Instead the rubber strap 9 is unhooked from a notch 12′, in which it would be hooked if a smartphone were to be attached to the smartphone stereoscope 1′. The curved arrow in FIG. 12 again shows how the lens holder 6 (indicated by dashed lines) is first pivoted outward by essentially 90° in order to move the smartphone stereoscope 1′ from the collapsed position into the unfolded position. The partition 5′ is then unfolded and interlocked with the lens holder 6, thus again producing the stable three dimensional structure.
[0076] Whereas FIG. 12 depicts a situation in which the smartphone stereoscope 1′ is in particular fixedly connected to the underside of the visor 23 [sic] of the baseball cap 23, FIGS. 13 and 14 show another variant. In this case the base 2′ is connected to a retaining clip 27, with which the smartphone stereoscope 1′ can be releasably fastened to the visor 22 of the baseball cap 23. This retaining clip 27 thus constitutes an alternative to the combination of a T-track 25 and a T-slot 24 in the exemplary embodiment described in the preceding for releasably fastening the smartphone stereoscope 1′ to the visor 22 of the baseball cap 23.
[0077] FIG. 13 also shows that the visor 22 can have crease lines 28 along which it can be folded over for compact storage of the baseball cap 23. These crease lines 28 run at an angle of ca. 20-60°, in particular 35°, to a forehead plane of a user who is wearing the baseball cap 23 with the visor in front and oriented forward. The arrangement according to FIG. 13 is shown again in FIG. 14, in a lateral view analogous to the depiction in FIG. 12.
[0078] Lastly, FIG. 15 shows another possible design of the invention, in which the baseball cap 23 is combined with a flexible hood 29, which in particular can be elastic, for example like a bathing cap, wherein this hood 29 can in particular be guided and pulled over the visor 22 and the smartphone stereoscope 1 and a smartphone 26 accommodated therein. To this end, the hood can in particular be fastened, for example hooked, on the bottom end of the partition 5. In this manner the user obtains a darkened area for especially good viewing of stereoscopic images displayed on his smartphone 26, without scattered light and other interfering incident light. Privacy is also better protected.
[0079] Alternatively, the hood 29 can also be used in a position other than the one shown in FIG. 15. It can be pulled back over the head portion of the baseball cap 23 and thus likewise guided over the viewer's head. An additional retaining force that secures the baseball cap 23 on the user's head is exerted by the elasticity of the hood 29, which in particular relieves and more effectively counteracts the weight force, and consequently the tilting moment, exerted on the baseball cap 23 by the smartphone stereoscope 1 and especially by the smartphone 26 accommodated therein.
[0080] The preceding description of exemplary embodiments is purely an illustrative one, wherein individual features of the exemplary embodiments can also be combined with one another, as persons skilled in the art would obviously do. Other design variants not described here likewise fall within the general breadth and scope of the invention, as it is described in the following claims.
