The amount of precision (tolerances) required for the positioning may depend on the type and magnitude of the correction. Since wearers differ from one another in the shapes and configurations of their heads and faces there are available eyeglasses of various sizes and shapes, so as to fit to the specific wearer's face. Furthermore, for many eyeglasses are considered to be a fashion accessory, and thus eyeglass frames are found in a variety of designs.
  • One common method of fitting an eyeglass frame to a wearer's face is to select an eyeglass frame that approximately fits the face.

  • the amount of bending to which the frames may be subjected without breaking or damaging the frame is limited.
  • fit adjustments are typically limited to relatively small adjustments.
  • a fit may be limited by the availability of a particular style of frame in a particular size.
  • Frames have therefore been described in which one or more components are adjustable so as to accommodate the frame to a greater range of dimensions of the face of a wearer.
  • trial frames that are employed in testing vision include several such adjustable elements with numerical scales for accommodating and measuring distances on the face.

In order to function properly, the dimensions of the spectacle frame may be compatible with those of the face of the wearer. For example, in order for corrective eyeglasses to correct a wearer's vision properly and without causing eyestrain, the lenses may be positioned at a prescribed position relative to the wearer's eyes. The amount of precision (tolerances) required for the positioning may depend on the type and magnitude of the correction. Since wearers differ from one another in the shapes and configurations of their heads and faces there are available eyeglasses of various sizes and shapes, so as to fit to the specific wearer's face. Furthermore, for many eyeglasses are considered to be a fashion accessory, and thus eyeglass frames are found in a variety of designs.
[0003] One common method of fitting an eyeglass frame to a wearer's face is to select an eyeglass frame that approximately fits the face. In order to adjust the fit more exactly to the face, a spectacle fitter (e.g. an optician or optometrist) may then bend one or more components of the frame. For many spectacle frame materials, the amount of bending to which the frames may be subjected without breaking or damaging the frame is limited. Thus, such fit adjustments are typically limited to relatively small adjustments. Thus, a fit may be limited by the availability of a particular style of frame in a particular size.
[0004] Frames have therefore been described in which one or more components are adjustable so as to accommodate the frame to a greater range of dimensions of the face of a wearer. For example, trial frames that are employed in testing vision include several such adjustable elements with numerical scales for accommodating and measuring distances on the face. The adjustable elements typically include telescoping elements and sets screws that are easily visible and manually accessible. Such frames are generally very heavy, and are typically not considered to be practical or esthetically pleasing for everyday eyeglass wear.
[0005] Adjustable eyeglass frames for everyday eyeglass wear have also been described. For example, Heel (DE 4307661) has described a continuously adjustable spectacle frame in which the length of the nose bridge is adjustable by threading threaded rods into or out of threaded sleeves. Dudelko (US 2,856,713) describes a spectacle frame with a similarly adjustable bridge, also including similarly adjustable temples. Ratti (GB 252,008) describes a bridge formed by plates that may slide relative to one another in order to adjust the width of the frame, and which may fixed by means of a tooth that engages one of multiple recesses in one of the plates. Hiroshi et al. (JP 4141620) describe spectacles in which the frame or lenses are provided with multiple bored holes enabling selection of the width of the frame and the placement of nose pads. Van Neste (US 4,826,309) describes an eyeglass frame in which the lengths of the arms of the frame may be adjusted using (accordion-like) hollow resilient fluted coupling members.
[0006] It is an object of the present invention to provide a spectacle frame in which the width of the frame may be adjusted in a stable and esthetically appealing manner.
[0007] Other aims and advantages of the present invention will become apparent after reading the present invention and reviewing the accompanying drawings. SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF EMBODIMENTS
[0037] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, modules, and/or units have not been described in detail so as not to obscure the invention.
[0038] An adjustable spectacle frame in accordance with an embodiment of the present invention includes an adjustable nose bridge that connects two lens holders. The adjustable nose bridge includes a removable angled insert. The angled insert includes two arms that diverge from one another.
[0039] The angled nose bridge insert is bent into the approximate form of a V-shaped element. The divergence of the arms from one another may be characterized by, for example, an opening angle between the arms (e.g. V-shaped). Alternatively, the arms may be continuously curved (e.g. U-shaped or C-shaped). The arms of the angled insert may typically have circular cross sections. However, the arms may have rectangular, elliptic, polygonal, or any other shaped cross sections.
[0040] The adjustable spectacle frame typically includes two lens holders that are configured for placement on either side of the nose of a wearer. A proximal side (a side of each lens holder that is nearest to the other lens holder when the lens holders are assembled into a spectacle frame) of each lens holder includes a sloped channel into which an arm of the angled nose bridge insert may be inserted. When both arms of the angled nose bridge insert are inserted into the sloped channels of the lens holders, the angled nose bridge insert forms at least part of a nose bridge that connects the two lens holders. The lens holders together with the angled nose bridge form a front section of the spectacle frame.
[0041] A distance between the two lens holders may be changed by changing the length of each arm of the angled nose bridge insert that is inserted into the sloped channel of its corresponding lens holder. Each sloped channel may be oriented (with respect to the lens holder) such that when the arms of the angled nose bridge insert are inserted into the sloped channel, the lens holders are oriented at a desired angle with respect to one another. (The orientation may be such that the lens holders are oriented at a desired angle to the vertical when worn upright on the face of the wearer. For example, each sloped channel may form an angle with respect to the vertical that is equal to half of the opening angle between the arms of the angled nose bridge insert.
[0042] Typically, each lens holder also includes an approximately horizontal (when the spectacle frame is being worn by a wearer that is standing erect with head held erect) channel. Each horizontal channel has an opening at its proximal end. The ends of a substantially straight bridge bar may be inserted into the openings of the horizontal channels, thus forming an additional connection between the lens holders. The bridge bar may typically have a circular cross section. However, the bridge bar may have a circular, rectangular, elliptical, polygonal, or any other shape of cross section. The bridge bar may be slightly curved in order to achieve a desired esthetic or stylistic effect. In this case, the lens holders may be designed to cooperate with the curved bridge bar in order to achieve a desired overall appearance or structure of the adjustable spectacle frame.
[0043] The channels, as well as the other parts of the lens holder, such as a rim, may be constructed of materials that are typically used in constructing spectacle frames. Such materials include, for example, materials containing polymers (e.g. based on cellulose acetate or nylon), metals (e.g. metals such as, or alloys based on, titanium, steel, beryllium, aluminum, silver, or gold), carbon fiber, evlar, other organic materials (e.g. wood or horn), or composites of the above.
[0044] At the points where the angled nose bridge insert crosses the horizontal bar, the angled nose bridge insert and the horizontal bar may be attached to one another. For example, each arm of the angled nose bridge insert may include a series of indentations or notches. The horizontal bar may be engaged by a pair of the notches (one notch on each arm of the angled nose bridge insert). Thus, the horizontal bar may additionally fix a vertical position of the angled nose bridge insert relative to the horizontal bar and the lens holders. Fixing the vertical position of the angled nose bridge insert may thus fix a distance between the lens holders. The combination of the angled nose bridge insert and the horizontal bar, forming an A-shaped nose bridge structure, may provide additional rigidity to the spectacle frame. In some designs, connecting the angled nose bridge insert and the horizontal bar may also serve to close a rim of the lens holder.
[0045] The sloped channels, the horizontal channels, or both may be provided with structure for fixing or maintaining the length of the bars that are inserted into the channels (e.g. thus fixing relative distance or orientation between the lens holders). For example, a sloped channel, a horizontal channel, or both may be provide with one or more set screws or similar structure and/or means for fixing a length of an arm or bar that is inserted into the channel.
[0046] Each lens holder, in addition to its sloped and the horizontal channels, includes a lens holding structure. The lens holding structure may include a full or partial rim, or any form that is capable of supporting a suitably shaped lens, and that is compatible with the provision of the sloped and horizontal channels. Details of the lens holding structure may be determined by esthetic, stylistic, or other design or functional considerations. For example, the lens holding structure may be designed so as to disguise or minimize the visibility of the sloped and horizontal channels, or to prevent injury from contact with a protruding end of an inserted arm or bar.
[0047] A spectacle frame in accordance with embodiments of the present invention may include additional structure so as to enable the spectacle frame to sit in a desired manner on the face of a wearer. Such additional structure may include, for example, nose pads or other structure to enable the wearers nose to properly support and hold in place the spectacle frame. Typically, the spectacle frame is provided with temple arms for enabling the wearer's ears, or the sides of the wearer's head, to hold the spectacle frame in place.
[0048] Reference is now made to the accompanying Figures.
[0049] Fig. 1 shows a frontal view of a spectacle frame with an adjustable nose bridge in accordance with an embodiment of the present invention. Fig. 2 shows a front section of another spectacle frame with an adjustable nose bridge in accordance with another embodiment of the present invention. Adjustable spectacle frame 10 includes two lens holders 11 that are connected by adjustable nose bridge 13.
[0050] Adjustable nose bridge 13 may be adjusted so as to determine a distance or relative orientation between lens holders 11. For example, the distance may be adjusted such that temple arms 24 may fit comfortable or firmly about a wearer's head. In the case where lens holders are holding corrective lenses, a distance or relative orientation of lens holders 11 may be adjusted so as to properly position the corrective lenses in front of the wearer's eyes. If the purpose of lenses held by lens holders 11 is protective or decorative (e.g. sunglasses), a distance may be adjusted in order to achieve a desired functional, esthetic, or stylistic effect. (In the case of corrective lenses also, adjustable spectacle frame 10 may be adjusted to achieve a decorative effect. However, in this case the corrective lenses may require proper design and shaping so as to achieve the required correction in the selected configuration of adjustable spectacle frame 10).
[0051] Adjustable nose bridge 13 includes angled insert bar 12 and horizontal bar 18. Angled insert bar 12 may be constructed out of a material that provides sufficient mechanical strength or stiffness to connect lens holders 11 to form adjustable spectacle frame 10. For example, angled insert bar 12 may typically be constructed out of a metallic wire, rod, or bar. For example, the metallic material may include a metallic material that is typically included in spectacle frames. Such metallic materials may include, for example, alloys of steel, titanium, aluminum, or beryllium. In accordance with such considerations as endurance, esthetics, comfort, or safety, a metal wire or rod of angled insert bar 12 may be coated, anodized, insulated, or covered with a suitable coating or covering material or sleeve. Alternatively, angled insert bar 12 may be constructed of a polymer, wood, or any other organic or not organic material that is capable of being appropriately shaped and that has appropriate mechanical properties to function as angled insert bar 12.
[0052] Angled insert bar 12 may include two arms 14, Each arm 14 may be inserted into a sloped channel 16 of a lens holder 11. The length of each arm 14 that is inserted into a sloped channel 16 is selectable. For example, the inserted length may be continuously variable or may be limited to one of a set of predetermined lengths. For example, a set of discrete lengths may be determined by the locations of structure such as stops, teeth, grooves, ridges, notches, bosses, or indentations along arm 14 or sloped channel 16 (or both). The structure on either of arm 14 or sloped channel 16 may then be configured to engage cooperating structure on the other. A set of predetermined lengths may be determined by locations of notches on arms 14 that are configured to engage horizontal bar 18 of adjustable nose bridge 13.
[0053] An arm 14 of angled insert bar 12 that is inserted into a sloped channel 16 may be held in place by structure of sloped channel 16. Such structure may include, for example, set screws, clamps, or clips.
[0054] Horizontal bar 18 is typically in the form of an approximately straight rod, bar, or wire. The construction of horizontal bar 18 may be similar in its composition to that of angle insert bar 12 (e.g. a coated or bare metal, or a polymer or other material that is capable of being appropriately shaped and having suitable mechanical properties). Each end of horizontal bar 18 may be inserted into horizontal channel 20 of a lens holder 11. Each inserted end may be held in place by structure of horizontal channel 20, such as a set screw.
[0055] Changing a separation between lens holders 11 typically requires concurrently changing both the length of each arm 14 of angled insert bar 12 that is inserted into sloped channel 16 of each lens holder 11, and the length of horizontal bar 18 that is inserted into horizontal channel 20 of each lens holder 11. Thus, typically, adjustment of insertion of angled insert bar 12 and of horizontal bar 18 entails changing both in coordination with one another. Also typically, the lengths of arms 14 that are inserted into sloped channels 16 of two lens holders 1 1 of a single adjustable spectacle frame 10 are equal to one another. Concurrent adjustment of the inserted lengths of arms 14 and of the ends of horizontal bar 18 enables modifying the distance separating the two lens holders 11 of adjustable spectacle frame 10.
[0056] Due to the divergence of arms 14 from one another, inserting a greater length of arm 14 into sloped channel 16 shortens the distance between lens holders 1 1. The length of horizontal bar 18 that is inserted into one or both of horizontal channels 20 may be changed accordingly.
[0057] Alternatively, to coordinated and concurrent adjustment of the inserted lengths of arms 14 of angled insert bar 12, and of the inserted lengths of the ends of horizontal bar 18, so as to adjust a separation distance between lens holders 11, an adjustment may alter the relative orientations of lens holders 11. For example, the lengths of the ends of horizontal bar 18 that are inserted into horizontal channels 20 may be fixed. In this case, a change in the lengths of arms 14 that are inserted into sloped channels 16 of lens holders 1 1 may apply a force that tends to change the separation distance between lower ends (when worn) of lens holders 11. However, the separation distance between the upper ends of lens holders may remain approximately constant since the lengths of the inserted ends of horizontal bar 18 do not change. The result is adjustment of a force that tends to rotate the lower ends of lens holders 11 toward or away from one another (depending on whether arms 14 are inserted into, or removed from, respectively, sloped channels 16). The force also applies a bending stress to horizontal bar 18. An actual change in relative orientations between lens holders 11, and thus the shape of adjustable spectacle frame 10, may depend, therefore, on mechanical properties of angled insert bar 12, of horizontal bar 18, and of sloped channels 16 and horizontal channels 20. Such mechanical properties may include various elastic moduli of the various elements. For example, the relative orientation of lens holders 11 may be modified in order to attain a particular esthetic or stylistic effect.
[0058] Alternatively, if the insert bar has curved arms, rather than straight diverging arms as does angled insert bar 12, changing the length of the curved arm that is inserted into a sloped channel 16 may concurrently change a distance between lens holders 11, and an relative orientation between lens holders 11.
[0059] Changing a separation distance or relative orientation between lens holders 1 1 may entail making other adjustments to adjustable spectacle frame 10. Such adjustments may be made, for example, to ensure that adjustable spectacle frame 10 fits comfortably and securely on the face of the wearer. Such adjustments may include, for example, shaping or otherwise modifying temple arms 24, adjusting or shaping temple connection 26 (which may be in the form of, for example, a hinge, spring, or flexible connector), or adjusting a position of nose pads 34.
[0060] Angled insert bar 12 and horizontal bar 18 may be configured so as to engage one another to form an A-shaped structure.
[0061] Fig. 3 shows a rear view of the adjustable nose bridge of the spectacle frame shown in Fig. 1. Fig. 4 shows an adjustable nose bridge of another spectacle frame in accordance with an embodiment of the present invention. [0062] As shown in Fig. 3 and Fig. 4, each arm 14 of angled insert bar 12 is provided with a series of notches 28. Typically, notches 28 on arms 14 are arranged in a symmetric manner such that there is a one-to-one correspondence between each notch 28 on one arm 14 and a corresponding notch 28 on the other. Thus, corresponding notches 28 on each of arms 14 are at approximately equal positions along arms 14 (e.g. at approximately equal distances from an end of arm 14 or from a vertex of angled insert bar 12).
[0063] Each notch 28 is of such size and shape so as to enable horizontal bar 18 to fit within the notch 28. A symmetric arrangement of notches 28 enables two notches 28, one on each arm 14, to engage horizontal bar 18. For example, horizontal bar 18 is shown as engaged by a pair of symmetrically arranged notches 28a. When horizontal bar 18 is engaged by notches 28a on arms 14, horizontal bar 18 and angled insert bar 12 are interlocked to form adjustable nose bridge 13 that includes an A-shaped structure. The A- shaped structure that is included in adjustable nose bridge 13 may enhance the strength and stability of adjustable nose bridge 13 and of adjustable spectacle frame 10.
[0064] Due to esthetic and stylistic considerations, notches 28 are typically located on an inward-facing side of angled insert bar 12. However, notches 28 may be located on either side, or both sides, of angled insert bar 12. Notches 28 may be appropriately sloped or angled so as to inhibit horizontal bar 18 from working free of notches 28a. Similarly, notches 28 may be shaped (e.g. in the form of approximately horizontal grooves if the width of each arm 14 of angled insert bar 12 is sufficiently large) so as to inhibit relative rotation between horizontal bar 18 and an arm 14 of angled insert bar 12.
[0065] Adjustable spectacle frame 10 may be configured so as to retain a particular adjusted configuration of adjustable nose bridge 13. For example, each sloped channel 16 may be provided with sloped channel set screw 30 to fix a length of an arm 14 of angled insert bar 12 that is inserted into sloped channel 16. Alternatively, slope channel 16 may be provided with a pin, clamp, or other arrangement for holding or fixing a length of arm 14 within sloped channel 16. Similarly, horizontal channel 20 may be provided with a horizontal channel set screw 32 for fixing an inserted length of horizontal bar 18 within horizontal channel 20.
[0066] An adjustable nose bridge in accordance with embodiments of the present invention may be adapted to a variety of spectacle frames and styles. Some examples of such spectacle frames are illustrated in Figs. 5A-5D. A spectacle frame with adjustable nose bridge in accordance with embodiments of the present invention may be made of various spectacle frame materials known in the art (e.g. metals and alloys, plastics and polymers, or other organic materials), and with a variety of rim styles.
[0067] Fig. 5A illustrates a spectacle frame with adjustable nose bridge having a substantially trapezoidal rim in accordance with an embodiment of the present invention.
[0068] In exemplary spectacle frame 34a, each sloped channel 16 and horizontal channel 20 is incorporated into a lens holder with full trapezoidal rims 36a. Each full trapezoidal rim 36a is in the approximate shape of a trapezoid with rounded corners. A full rim, such as full trapezoidal rim 36a, may be designed to hold a lens independently of adjustment or assembly of exemplary spectacle frame 34a. Full trapezoidal rim 36a is of such dimensions that sloped channel 16 and horizontal channel 20 are completely incorporated into full trapezoidal rim 36a. Thus, sloped channels 16 and horizontal channels 20 may not be readily discernable as separate structure. For example, full trapezoidal rims 36a may be made of a plastic polymer material.
[0069] Fig. 5B illustrates a spectacle frame with adjustable nose bridge having a substantially quadrilateral rim in accordance with an embodiment of the present invention.
[0070] In exemplary spectacle frame 34b, each sloped channel 16 and horizontal channel 20 is incorporated into a lens holder with a partially quadrilateral rim 36b. Each partially quadrilateral rim 36b is in a form that resembles a quadrilateral with rounded comers.
Partially quadrilateral rim 36b is of such dimensions that sloped channels 16 and horizontal channels 20 are completely incorporated into partially quadrilateral rim 36b.
Thus, sloped channels 16 and horizontal channels 20 may not be readily discernable as separate structure. For example, partially quadrilateral rim 36b may be made of a plastic polymer material.
[0071] Partially quadrilateral rim 36b is open at section 38. Thus, in this case, adjustable nose bridge 13 may serve to close partially quadrilateral rim 36b in order to hold a lens in place. For example, as described above and shown in Fig. 3 and Fig. 4, a pair of notches 28 on arms 14 of angled insert bar 12 may engage and hold horizontal bar 18. Thus, by engaging horizontal bar 18, angled insert bar 12 and horizontal bar 18 may cooperate so as to close partially quadrilateral rim 36b. Alternatively, section 38 may be closed by a thin continuation of partially quadrilateral rim 36b. For example, the continuation may be made thin (e.g. of a metallic material) so as not to be readily visible when viewed from a typical viewing distance (e.g. a typical separation distance between two people that are conversing with one another).
[0072] Fig. 5C illustrates a spectacle frame with adjustable nose bridge having a substantially circular rim in accordance with an embodiment of the present invention.
[0073] In exemplary spectacle frame 34c, each sloped channel 16 and horizontal channel 20 is incorporated into a lens holder with partially circular rim 36c. Each partially circular rim 36c is in a form that resembles a partially opened circle. Partially circular rim 36c is of such dimensions that sloped channels 16 and horizontal channels 20 are completely incorporated into partially circular rim 36c. Thus, sloped channels 16 and horizontal channels 20 may not be readily discemable as separate structure. For example, partially circular rim 36c may be made of a plastic polymer material.
[0074] Partially circular rim 36c is open at section 38. Thus, in this case, adjustable nose bridge 13 may serve to close partially circular rim 36c in order to hold a lens in place. For example, as described above and shown in Fig. 3 and Fig. 4, a pair of notches 28 on arms 14 of angled insert bar 12 may engage and hold horizontal bar 18. Thus, by engaging horizontal bar 18, angled insert bar 12 and horizontal bar 18 may cooperate so as to close partially circular rim 36c. Alternatively, section 38 may be closed by a thin continuation of partially circular rim 36c. For example, the continuation may be made thin (e.g. of a metallic material) so as not to be readily visible when viewed from a typical viewing distance (e.g. a typical separation distance between two people that are conversing with one another).
[0075] Fig. 5D illustrates a spectacle frame with adjustable nose bridge having a partial rim in accordance with an embodiment of the present invention.
[0076] In exemplary spectacle frame 34d, each sloped channel 16 and horizontal channel 20 is incorporated into a lens holder with partial rim 36d. Partial rim 36d is designed to hold part of the perimeter of a suitably shaped lens. A part of the perimeter of the lens may be bonded to (e.g. mechanically held by, screwed or bolted to, or adhesively held by) partial rim 36d. In exemplary spectacle frame 34d, depending on the strengths or other properties of partial rim 36d, a lens being held by partial rim 36d may provide or contribute to mechanical strength of (e.g. resistance to bending or twisting of) exemplary spectacle frame 34d.
[0077] Sloped channel 16 and horizontal channel 20 are typically readily discernable as a discrete structure of partial rim 36d. For example, partial rim 36d may be made of a metallic material, while sloped channel 16 and horizontal channel 20 may each be made of a plastic polymer material. Sloped channel 16 and horizontal channel 20 may be bonded or affixed to partial rim 36d using any bonding means known in the art.
[0078] Exemplary spectacle frames 34a-34d are illustrative of various features of spectacle frames with adjustable nose bridges, in accordance with embodiments of the present invention. Features of exemplary spectacle frames 34a-34d may be combined with one another, or with other features of spectacle frames known in the art, to form various variations of spectacle frames in accordance with embodiments of the present invention. For example, a full rim may be in a form other than a trapezoidal form (e.g. circular or quadrilateral), and a partial rim may have a trapezoidal or other form.
[0079] A spectacle frame with an adjustable nose bridge, in accordance with an embodiment of the present invention, may be provided in the form of a kit. Components of the kit may be selected for assembly into an adjustable spectacle frame. Such a kit may include, for example, lens holders. The lens holders may include lens holders of a particular type. Alternatively, the lens holders included in the kit may include a particular type (e.g. style) of lens holder in various variations. Such variations may include various sizes, colors or finishes, or materials. Alternatively, the lens holders included in the kit may include various styles of lens holders. Each lens holder of the kit may be attached to a temple arm. Alternatively, temple arms (and any screws or other component used to attach a teniple arm to a lens holder) may be included as separate components of the kit. Similarly, nose pads may be provided as part of a lens holder, or may be provided separately as part of the kit.
[0080] Other components of the kit may include angled insert bars, horizontal bars, and set screws (or pins or other elements for fixing an length of a bar or arm that is inserted into a channel). The angled insert bars and horizontal bars that are provided with the kit may all be similar to one another, or may vary from one another. For example, the kit may include a selection of various angled insert bars and horizontal bars. The angled insert bars and horizontal bars that are provided with the kit may vary from one another in size, strength, color, finish, cross-sectional shape, or style.
[0081] Thus, a spectacle frame with an adjustable nose bridge, in accordance with an embodiment of the present invention, may be assembled from components of the kit. Depending on availability, on arrangements with suppliers, or on the style of the spectacle frame, the spectacle frame may be assembled separately of a lens, or with a lens in place. For example, a partial rim such as partially quadrilateral rim 36b and partially circular rim 36c may require that a lens be inserted within the rim prior to assembly.
