Description

Spectacle frame with adjustable nose piece

technical field

The present invention relates to eyeglasses, and more particularly, to eyeglass frames with adjustable nosepieces.

Background technique

Glasses are worn for a variety of purposes, including vision correction and eye protection. To function properly, the spectacle frames may be sized to fit the wearer's face. For example, in order for corrective eyewear to correct the wearer's vision without causing eye fatigue, the lenses may be located at designated positions relative to the wearer's eyes. The exact amount (bias) required for positioning may depend on the type and magnitude of the correction. Since wearers' heads and faces vary in shape and contour, eyewear is available in individual sizes and styles to fit the specific wearer's face. Further, many eyeglasses are considered a fashion accessory, and thus eyeglass frames are found in a variety of designs.

A common method of fitting spectacle frames to the wearer's face is to choose spectacle frames that roughly fit that face. In order to adjust the glasses to better fit the face, a spectacle fitter (such as an optician or optometrist) may bend one or more components of the spectacle frame. For many spectacle frame materials, there is a limit to the angle of bending the frame can withstand without breaking or damaging the frame. Therefore, such adaptations are usually limited to relatively small adjustments. Therefore, adaptation is limited by the availability of a particular type of frame at a particular size.

Spectacle frames having one or more adjustable members such that the frame can accommodate a wider range of wearer's face sizes have thus been described. For example, test frames for testing eyesight include adjustable elements with numerical scales for fitting to and measuring distances on the face. These adjustable elements typically include easily visible and manually operable retractable elements and set screws. These frames are often heavy and generally do not have the practicality and aesthetics of everyday eyewear.

Adjustable eyeglass frames worn as everyday eyeglasses have also been described. For example, Hale describes a continuously adjustable spectacle frame in DE 4307661, the length of its nose bridge is regulated by passing a screw rod into and out of a threaded sleeve. Dudeko in US 2,856,713 describes a spectacle frame with a similar adjustable nose bridge, also including similar adjustable temples. Rati in GB 252,008 describes a spectacle bridge formed of plates that can slide relative to each other to adjust the width of the frame, and which is secured by teeth engaging one of the recesses of one of the plates. Hiroshi Fujiwara et al. describe a kind of spectacles in JP 4141620, and its frame or lens has a plurality of drilling holes to make it possible to choose the width of the frame and replace the nose pad. Van Nesty in US 4,826,309 describes a spectacle frame that uses (accordion-like) hollow elastic slotted joint members to adjust the length of the frame arms.

The object of the present invention is to provide a spectacle frame whose width can be adjusted stably and aesthetically.

Other objects and advantages of the present invention will appear after reading the present disclosure and examining the accompanying drawings.

Detailed ways

In the following detailed description, a full understanding of the invention will be provided by setting forth specific details. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, descriptions of well-known methods, procedures, components, modules and/or units are omitted so as not to obscure the description of the present invention with unnecessary detail.

An adjustable spectacle frame according to one embodiment of the present invention includes an adjustable nose bridge connecting two lens holders. The adjustable nosepiece includes removable angled inserts. The angled insert comprises two arms separated from each other.

The angled nosepiece insert is curved to approximate the shape of a V-shaped element. The arms diverging from each other are characterized, for example, by an open angle (eg V-shape) between the two arms. Optionally, the arms may be continuously curved (eg U-shaped or C-shaped). The arms of the angled insert may generally have a circular cross-section. However, the arm may have a rectangular, elliptical, polygonal or any other shaped cross-section.

The adjustable spectacle frame generally includes two lens holders for placement on either side of the wearer's nose. The proximal end of each lens holder (the end of each lens holder closest to the other when the lens holder is assembled into a spectacle frame) includes angled channels into which the arms of the angled nosepiece inserts may be inserted. When both arms of the angled nose bridge insert are inserted into the angled channel of the lens holder, the angled nose bridge insert forms at least part of a nose bridge connecting two lens holders. The lens holder together with the angled nose piece forms the front of the spectacle frame.

The distance between the two lens holders can be varied by varying the length of the arms of the angled nosepiece inserts inserted into the corresponding inclined channels of the lens holders. Each angled channel may be positioned (relative to the lens holder) such that the lens holders are oriented to a predetermined angular position relative to each other when the arms of the angled nose bridge insert are inserted into the angled channel. The positioning may be such that the lens holder is positioned at a predetermined angle relative to the vertical when it is worn vertically on the wearer's face. For example, each angled channel may form an angle with respect to the vertical equal to half the opening angle between the arms of the angled nose bridge insert.

Typically, each lens holder also includes channels that are approximately horizontal (when the spectacle frame is worn on the face of a wearer who stands upright and holds his head upright). Each horizontal channel is open at its proximal end. A generally straight bridging rod can be inserted into the opening of the horizontal channel, thereby forming an additional connection between the lens holders. The bridging bars generally have a circular cross-section. However, the bridging bar may have a circular, rectangular, elliptical, polygonal or any other cross-section. The bridging bars may be slightly bent for desired aesthetic or style effects. In this case, the lens holder is designed to cooperate with the curved bridging rods to achieve the desired overall appearance or configuration of the adjustable spectacle frame.

The channels, as well as other parts of the lens holder, such as the frame, may be constructed of materials commonly used to construct spectacle frames. Such materials include, for example, polymer-containing materials (e.g., based on cellulose acetate or nylon), metals (e.g., metals such as titanium, steel, beryllium, aluminum, silver, or gold, or alloys based on these metals), carbon fiber , Kevlar, other organic materials such as wood or horn, or combinations of the above.

The angled nose bridge insert and the horizontal bar may be connected to each other where the angled nose bridge insert passes through the horizontal bar. For example, each arm of the angled bridge insert may include a series of notches or notches. The horizontal bar can be engaged by a pair of notches, one for each arm of the angled nosepiece insert. Thus, the horizontal bar also secures the angled nose bridge insert in a vertical position relative to the horizontal bar and lens holder. The horizontal position of the angled nose bridge insert is fixed so that a distance can be defined between the lens holders. The combination of angled bridge inserts and horizontal rods that form an A-shaped bridge structure can provide additional rigidity to the spectacle frame. In some designs, connecting the angled bridge insert and the horizontal bar may also be used to close the frame of the lens holder.

The inclined channel, the horizontal channel, or both have structures that fix or maintain the length of the rod inserted into the channel (eg, thereby fixing the relative distance or orientation between the lens holders). For example, said inclined channel, said horizontal channel or both have one or more set screws or similar structures and/or means for fixing the length of an arm or rod inserted into the channel.

In addition to its inclined channel and horizontal channel, each lens holder also includes a lens fixing structure. The lens holding structure may include full or partial rims, or any form capable of supporting lenses of appropriate shape and compatible with inclined and horizontal channels. The details of the lens attachment structure may be dictated by aesthetic, stylistic, or other design or functional considerations. For example, the lens securing structure may be designed to hide or minimize visibility of the inclined and horizontal channels, or to avoid damage from contact with the protruding end of an inserted arm or rod.

Spectacle frames according to embodiments of the present invention may include additional structures that enable the spectacle frame to fit on the wearer's face in a desired manner. Such additional structures may include, for example, nose pads or other structures that enable the wearer to properly support and secure the spectacle frames. Typically, the spectacle frame has temples so that the spectacle frame can be properly secured on the wearer's ears or on either side of the head.

Description will now be made with reference to the accompanying drawings.

Figure 1 is a front view of a spectacle frame with an adjustable nose bridge in one embodiment of the present invention. Fig. 2 is a front view of another spectacle frame with an adjustable nose bridge according to another embodiment of the present invention. The adjustable spectacle frame 10 includes two lens holders 11 connected by an adjustable nose piece 13 .

The adjustable nose piece 13 can be adjusted to determine the distance or relative orientation between the lens holders 11 . For example, adjusting the distance allows the temples 24 to fit comfortably or securely on the wearer's head. Where the lens holder holds the vision corrective lens, the distance and relative orientation of the lens holder may be adjusted to properly place the vision corrective lens in front of the wearer's eye. If the purpose of the lens fixed by the lens holder 11 is to play a protective or decorative role (such as sunglasses), the distance can be adjusted to achieve the desired functional, aesthetic or style effect. (For vision corrective lenses, adjustable spectacle frame 10 can also be adjusted to achieve decorative effects. However, in this case, corrective vision lenses may need to be properly designed and shaped to achieve the desired corrective effect after the spectacle frame 10 configuration is selected ).

The adjustable nose piece 13 includes an angled insertion rod 12 and a horizontal rod 18 . The angled insertion rod 12 may be constructed of a material having sufficient mechanical strength or rigidity to connect the lens holder 11 to form the adjustable spectacle frame 10 . For example, the angled insertion rod 12 may generally be formed from a wire, rod or rod. For example, metallic materials may include metallic materials commonly included in eyeglass frames. Such metallic materials may include, for example, alloys of steel, titanium, aluminum or beryllium. Depending on considerations such as durability, aesthetics, comfort, or safety, the wires or rods angled into the rod 12 may be plated, anodized, insulated, or covered with a suitable coating, covering material, or sheath. Tube. Alternatively, the angled insertion rod 12 may be constructed of polymer, wood, or any other organic or inorganic material that can be shaped appropriately and has suitable mechanical properties to function as the angled insertion rod 12 .

The angled insertion rod 12 may include two arms 14 . Each arm 14 may be inserted into an inclined channel 16 of the lens holder 11 . The length of insertion of each arm 14 into the inclined channel 16 is optional. For example, the length of the insertion may vary continuously, or be limited by one of a set of predetermined lengths. For example, a set of discrete lengths may be determined by the position of stops, teeth, grooves, ridges, indentations, protrusions, indentations, etc., along the arm 14 or inclined channel 16 (or both). Either arm 14 or angled channel 16 may be configured to engage mating structure on the other. A predetermined set of lengths may be determined by the position of the notch on the arm 14 for engagement with the horizontal bar 18 of the adjustable nose piece 13 .

The arm 14 of the angled insertion rod 12 inserted into the inclined channel 16 may be fixed in position by the structure of the inclined channel. Such structures may include, for example, set screws, clamps or clips.

Horizontal rod 18 is generally in the form of a generally straight rod, rod or wire. The composition of the horizontal rod 18 may be similar to that of the angled insert rod 12 (eg, plated metal, bare metal, polymer, or other material that can be shaped appropriately and has suitable mechanical properties). Each end of the horizontal rod 18 may be inserted into the horizontal channel 20 of the lens holder 11 . Each insertion end may be fixed in position by the structure of the horizontal channel 20, such as a set screw.

Changing the distance between the lens holders 11 typically requires simultaneously changing the length of each arm 14 of the angled insertion rod 12 inserted into the inclined channel 16 of each lens holder 11, and the length of the horizontal rod 18 inserted into the horizontal channel 20 of each lens holder 11. length. Therefore, insertion adjustments of the angled insertion rod 12 and the horizontal rod 14 typically require a cooperative change of both. Likewise, the lengths of the two arms 14 inserted into the inclined channels 16 of the two lens holders 11 of the single adjustable spectacle frame 10 are equal to each other. The concurrent adjustment of the insertion length of the arm 14 and the insertion length of the end of the horizontal rod 18 makes it possible to vary the distance between the two lens supports 11 of the adjustable spectacle frame 10 .

Since the arms 14 are diverged from each other, increasing the length of the arms 14 inserted into the inclined channels 16 will shorten the distance between the lens holders 11 . The length of the horizontal rod 18 inserted into one or both horizontal channels 20 may vary accordingly.

Optionally, for the coordinated and concurrent adjustment of the insertion length of the arm 14 of the angled insertion rod 12 and the insertion length of the end of the horizontal rod 18 to adjust the distance between the lens holders 11, the adjustment may change the relative orientation of the lens holders 11. orientation. For example, it is possible to fix the length of the end of the horizontal rod 18 inserted into the horizontal channel 20 . In this case, the change in length of the arm 14 inserted into the inclined channel 16 of the lens holder 11 may exert a force which tends to change the distance between the lower ends of the lens holder 11 (when worn). However, since the length of the insertion end of the horizontal rod 18 does not change, the distance between the upper ends of the lens holder may remain substantially constant. The result is an adjustment of the force which tends to turn the lower ends of the lens holder 11 towards or away from each other (depending on whether the arm 14 is inserted or moved out of the inclined channel 16 respectively). This force also applies bending stress to the horizontal rod 18 . Thus, the actual change in relative orientation between lens holders 11, and thus adjustable spectacle frame 10, may depend on the mechanical properties of angled insert rod 12, horizontal rod 18, inclined channel 16 and horizontal channel 20. Such mechanical properties may include various elastic moduli of various elements. For example, it is possible to vary the relative orientation 11 of the lens holders to achieve a particular aesthetic or stylistic effect.

Alternatively, if the insertion rod has curved arms instead of the straight forked arms of the angled insertion rod 12, changing the length of the curved arm inserted into the inclined channel 16 may change both the distance between the lens holders 11 and the distance between the lens holders 11. relative orientation between them.

Changing the separation distance or relative orientation between the lens holders 11 may require other adjustments to the adjustable spectacle frame 10 . For example, such adjustments may be made to ensure that the adjustable spectacle frame 10 fits comfortably and securely on the wearer's face. Such adjustments may include, for example, shaping or modifying the temples 24 , adjusting or shaping the temple connections 26 in the form of, for example, hinges, springs, or elastic joints, or adjusting the position of the nose pads 34 .

Angled insert bar 12 and horizontal bar 18 may be configured to engage each other to form an A-shaped structure.

Fig. 3 is a rear view of the adjustable nose bridge of the spectacle frame shown in Fig. 1 . Fig. 4 is an adjustable nose bridge of another spectacle frame according to an embodiment of the present invention.

As shown in FIGS. 3 and 4 , each arm 14 of the angled insertion rod 12 has a series of notches 28 . Typically the notches 28 on the arms 14 are arranged in a symmetrical manner such that each notch 28 on one arm 14 corresponds to a corresponding notch 28 on the other arm 14 . Accordingly, corresponding notches 28 on each arm 14 are located at approximately equal locations along the arms 14 (eg, at approximately equal distances from the ends of the arms 14 or the apexes of the angled insertion rods 12).

Each notch 28 has a size and shape that enables horizontal rod 18 to fit into notch 18 . The symmetrical arrangement of notches 28 enables the notches 28 respectively located on each arm 14 to engage with the horizontal bar 18 . For example, the horizontal bar 18 is shown engaging a pair of symmetrically arranged notches 28a. When the horizontal rod 18 is engaged by the notch 28a on the arm 14, the horizontal rod 18 and the angled insert rod 12 will snap together to form the adjustable nosepiece 13 comprising an A-shaped structure. The A-shaped structure included in the adjustable nose frame 13 can enhance the strength and stability of the adjustable nose frame 13 and the adjustable spectacle frame 10 .

The notch 28 is generally located on the inwardly facing side of the angled insertion rod 12 due to aesthetic and style considerations. However, the notches 28 may be located on either or both sides of the angled insertion rod 12 . The notches 28 may be suitably sloped or angled to prevent the horizontal bar 18 from being affected by the notches 28a. Similarly, the notch 28 may change shape (for example, if the width of each arm 14 of the angled insertion rod 12 is large enough, it may be shaped as a generally horizontal slot) to prevent the horizontal rod 18 and the angled insertion rod Relative rotation between the arms 14 of 12.

The adjustable spectacle frame 10 may be configured to hold a special adjustment configuration of the adjustable nosepiece 13 . For example, each angled channel 16 may have an angled channel set screw 30 for fixing the length of the arm 14 of the angled insertion rod 12 inserted into the angled channel 16 . Optionally, the inclined channel 16 may have pegs, clips or other arrangements for clamping or securing a length of arm 14 in the inclined channel 16 . Similarly, the horizontal channel 20 may have a horizontal channel set screw for fixing the insertion length of the horizontal rod 18 in the inclined channel 20 .

The adjustable nose bridge according to the present invention may be suitable for a wide variety of spectacle frames and styles. Figures 5A-5D illustrate some examples of such spectacle frames. Spectacle frames with adjustable nose bridges according to embodiments of the present invention can be made from various spectacle frame materials known in the art (e.g., metals and alloys, plastics and polymers, or other organic materials), and have various box type.

Figure 5A illustrates a spectacle frame including an adjustable nose bridge having a generally trapezoidal frame in one embodiment of the present invention.

In the exemplary spectacle frame 34a, each inclined channel 16 and horizontal channel 20 merge into a lens holder having a fully trapezoidal frame 36a. Each trapezoidal frame 36a is approximately trapezoidal with rounded corners. The purpose of designing a full frame, such as the full trapezoidal frame 36a, is to independently fix the lenses through the adjustment or assembly of the exemplary spectacle frame 34a. The full trapezoidal frame 36a has dimensions such that the inclined channel 16 and the horizontal channel 20 can completely fit into the full trapezoidal frame 36a. Accordingly, the inclined channel 16 and the horizontal channel 20 may not be as readily observable as separate structures. For example, the full trapezoidal frame 36a may be made of a plastic polymer material.

Figure 5B illustrates a spectacle frame having a generally quadrangular frame including an adjustable nosepiece in one embodiment of the present invention.

In the exemplary spectacle frame 34b, each oblique channel 16 and horizontal channel 20 merges into a lens holder having a partially quadrangular frame 36b. Each partial quadrilateral bracket 36b takes a quadrilateral-like form with rounded corners. The partial quadrangular frame 36b has dimensions such that the inclined channel 16 and the horizontal channel 20 can be completely integrated into the partial quadrangular frame 36b. Therefore, the inclined channel 16 and the horizontal channel 20 may not be as easily observed as separate structures. For example, part of the quadrangular frame 36b may be made of a plastic polymer material.

Partial quadrangular frame 36b opens in area 38 . Thus, in this case, the adjustable bridge 13 may be used to close part of the quadrangular frame 36b to secure the lens. For example, a pair of notches 28 on the arm 14 of the angled insertion rod 12 as described above and shown in FIGS. 3 and 4 may engage and grip the horizontal rod 18 . Thus, by engagement of the horizontal bar 18, it is possible for the angled insert bar 12 and the horizontal bar 18 to cooperate so as to close the partial quadrangular frame 36b. Alternatively, the area 38 may be closed by a thin extension of the partial quadrangular frame 36b. For example, the extension may be so small (eg, made of a metallic material) that it is not easily seen when viewed from a typical viewing distance (eg, the typical distance between two people chatting).

Figure 5C illustrates a spectacle frame with a generally circular frame including an adjustable nose bridge in one embodiment of the present invention

In the exemplary spectacle frame 34c, each inclined channel 16 and horizontal channel 20 merge into a lens holder having a partially circular frame 36c. Each partially circular frame 36a is approximately a partially open ring. The partially circular frame 36c has dimensions such that the inclined channel 16 and the horizontal channel 20 can completely fit into the partially circular frame 36c. Therefore, the inclined channel 16 and the horizontal channel 20 may not be as easily observed as separate structures. For example, the partially circular frame 36c may be made of a plastic polymer material.

Partial circular frame 36c opens in area 38 . Thus, in this case, the adjustable bridge 13 may be used to close the partially circular frame 36c to secure the lenses. For example, a pair of notches 28 on the arm 14 of the angled insertion rod 12 as described above and shown in FIGS. 3 and 4 may engage and grip the horizontal rod 18 . Thus, by engagement of the horizontal rod 18, it is possible for the angled insertion rod 12 and the horizontal rod 18 to cooperate so as to close the partially circular frame 36b. Alternatively, the area 38 may be closed by a thin continuation of the partially circular frame 36c. For example, the continuation may be so thin (eg, made of a metallic material) that it is not easily seen when viewed from a typical viewing distance (eg, the typical separation distance between two people chatting).

Figure 5D illustrates a spectacle frame with a partial frame including an adjustable nosepiece in one embodiment of the present invention.

In the exemplary spectacle frame 34d, each inclined channel 16 and horizontal channel 20 merge into a lens holder having a partial frame 36d. Partial frame 36d is designed to hold part of the edge of a suitably shaped lens. Part of the edge of the lens may be attached to part of the frame 36d (eg, mechanically secured by screws or bolts, or glued). In the exemplary spectacle frame 34d, depending on the strength or other characteristics of the partial frame 36d, the lenses secured by the partial frame 36d may provide or contribute to the mechanical strength (eg, resistance to bending or twisting) of the exemplary spectacle frame 34d.

Inclined channels 16 and horizontal channels 20 are generally readily visible as individual components of partial frame 36d. For example, the partial frame 36d may be made of a plastic polymer material, while the inclined channel 16 and the horizontal channel 20 may each be made of a plastic polymer material.

According to an embodiment of the present invention. Exemplary spectacle frames 34a-34d illustrate various features of spectacle frames with adjustable nose bridges. Features of the exemplary spectacle frames 34a-34d may be related to each other, or to other features of spectacle frames known in the art, to form variations of spectacle frames according to embodiments of the present invention. For example. A full frame may be of a form other than trapezoidal (such as a circle or quadrilateral), and a partial frame may have a trapezoidal or other form.

Spectacle frames with adjustable nose bridges according to embodiments of the present invention may be provided in kit form. Selected components of the kit may be used to assemble into adjustable spectacle frames. Such kits include, for example, lens holders. The lens holder may include a special type of lens holder. Optionally, the lens holders included in the kit may include variations of a particular type (eg, style) of lens holders. These variations may include various sizes, colors, finishes or materials. Optional lens holders included with the kit may include various styles of lens holders. Each lens holder of the kit may be attached to the temple. Optionally, the temples (and any screws or other components used to attach the temples to the lens holder) may be included in the kit as separate components. Similarly, nose pads may be provided as part of a lens holder or separately as part of a kit.

Other components of the kit may include angled insertion rods, horizontal rods, and set screws (or pegs or other elements for securing the length of the rod or arm inserted into the channel). The kit has angled insert bars and horizontal bars that are similar to each other, or different from each other. For example, the kit includes a variety of optional angled insert bars and horizontal bars. The set has angled insert bars and horizontal bars that may differ from each other in size, strength, color, section shape, or style.

Therefore, a spectacle frame with an adjustable nose bridge according to an embodiment of the present invention may be assembled from components of a kit. Depending on availability, supplier arrangements, or frame type, the frame may be assembled with the lenses alone, or with the lenses in place. For example, partial frames such as partial quadrilateral frame 36b and partial circular frame 36c may require lenses to be inserted into the frame prior to assembly.
