Description

  The present invention relates to a spectacle band that is attached to various spectacles such as eyesight correction glasses, reading glasses, protective glasses, and sunglasses, and is fixed so that the spectacles are not displaced from the wearing position of the face when the spectacles are worn.

  Conventionally, various techniques have been proposed to prevent glasses worn due to intense exercise or work from being displaced or detached from the wearing position.

  As such a technique, first, as shown in FIG. 4, it has a main body (1a) made of a band-shaped elastic fabric, and both ends of the main body (1a) are formed in a substantially cylindrical shape to form a mounting portion (1b). Each of the attachment parts (1b) is inserted and attached from the tip side of the vine part (5) of the glasses (3), and when wearing the glasses (3), the band-shaped main body (1a) is attached to the user. A spectacle band (1) is known that is locked to the back of the head and fixes the spectacles (3) so that they do not deviate from the wearing position of the face (see, for example, Patent Document 1).

  The eyeglass band (1) obtained with this technology can be easily attached to all kinds of eyeglasses, and the eyeglasses (3) are pressed against the face by the elastic recovery force of the main body (1a) locked to the back of the user when wearing eyeglasses. Therefore, even if intense exercise or work is performed, it is possible to prevent the glasses (3) from being displaced or detached from the wearing position.

  However, when the spectacle band (1) is attached to the spectacles (3), the entire attachment portion (1b) is once inserted into the horizontal portion (5a) of the vine portion (5) (see FIG. 4). ), In order to adjust the crimping force on the face of the glasses (3), pull the attachment part (1b) toward the tip of the vine part (5), and adjust the insertion length of the attachment part (1b) in the vine part (5). It needs to be adjusted. Here, in this spectacle band (1), the opening direction of the mounting portion (1b) and the moving direction of the mounting portion (1b) in the vine portion (5) are substantially the same. For this reason, even if the user adjusts the insertion length of the mounting part (1b) to the most suitable position, the opening part in the mounting part (1b) [particularly the vine part (5) attached to the main body of the glasses (3) If the stress in the rear end direction] is applied, the insertion length is easily changed. Therefore, for example, when the user removes the spectacles (3) wearing the spectacle band (1) from the face and wears it again, the insertion length of the wearing part (1b) shifts, and the pressing force on the user's face Often changes from a preferred state. In such a case, the insertion length of the mounting portion (1b) has to be adjusted again, which is troublesome.

  On the other hand, although not shown, a technique is known in which an attachment portion is provided in the vine portion of the glasses and a band portion made of an elastic body is attached to the attachment portion (see, for example, Patent Document 2). An embodiment provided with an adjustment tool for adjusting the length of the band portion is also disclosed. In the case of such a technique, if the length of the band portion is adjusted with an adjusting tool, unlike the above-described technique, it is possible to prevent the once-determined crimping force of the spectacle band from easily changing.

  However, the adjustment tool for adjusting the length of the band part is generally made of a member having hardness and strength different from those of the band part made of an elastic body. This means that hard parts are pressure-bonded to the head of the user, which causes the user's wearing feeling to deteriorate. Further, in order to attach this spectacle band to spectacles, it is necessary to provide a separate attachment portion at the vine portion of the spectacles, so that it is clear that it is not a form that can be easily attached and used to any spectacles.

Thus, the present condition is that the spectacles band which can be mounted | worn with all kinds of spectacles, has a good feeling of wear, and is easy to adjust the contact condition during wearing and to be easily attached or detached has not yet been disclosed.
U.S. Pat. No. 4,133,604 (page 1-4, FIG. 1) JP-A-8-166564 (page 2-5, FIG. 1)

  Therefore, a main object of the present invention is to provide a spectacle band that can be attached to all kinds of spectacles, has a good wearing feeling, and can be easily adjusted and attached / detached while wearing.

  According to the first aspect of the present invention, “when wearing the spectacles (12) by connecting the vine portions (14) of the glasses (12) to each other, when wearing the glasses (12), A spectacle band (10) for fixing the spectacles (12) so that it does not deviate from the wearing position of the face, and at least both ends (10a) to be attached to the vine portion (14) of the spectacles (12) are made of elastic yarn. The yarn (16) is knitted so as to be provided with a stitch (18) ".

  In the spectacle band (10) of the present invention, the vine portion (14) of the spectacles (12) is simply inserted through the plurality of stitches (18) provided at both ends (10a) of the spectacle band (10). The spectacle band (10) can be easily attached to the spectacles (21).

  The stitches (18) provided at both ends (10a) are constituted by yarns (16) made of elastic yarns, and the size of the stitches (18) can be easily expanded or reduced. Therefore, the vine portion (14) having various thicknesses and shapes can be inserted into the stitch (18), and thus the spectacle band (10) can be attached to all kinds of spectacles (3).

  In addition, the length of the eyeglass band (10) that connects the vines (14) can be adjusted simply by adjusting the position of the stitches (18) that penetrate the vines (14) without using an adjustment tool. It is possible to adjust the pressing force of the glasses (12) to the face to the most suitable state without impairing the wearing feeling.

  And since the length of the spectacle band (10) connecting the vine parts (14) is uniquely determined by the position of the stitch (18) penetrating the vine part (14), the vine part (14) The length once determined does not change unless the position of the stitch (18) penetrating the wire is changed, and readjustment is unnecessary.

  The invention described in claim 2 is the eyeglass band (10) according to claim 1, wherein the elastic yarn includes at least one of polyurethane elastic yarn, natural rubber yarn and synthetic rubber yarn. By using these elastic yarns having a high friction coefficient, high friction occurs between the stitch (18) and the vine portion (14) of the glasses (12) inserted through the stitch (18), and the spectacle band (10). It is possible to prevent the both end portions (10a) of the lens from coming off from the vine portion (14) of the glasses (12).

  This friction is also exerted when water intervenes, so for example, when the user sweats due to intense luck or work, the spectacle band (10) gets wet, or it is used in an environment where it gets wet such as marine sports. Even in this case, it is possible to prevent the spectacle band (10) from being detached from the vine portion (14) of the spectacles (12).

  According to the present invention, since at least both ends of the spectacle band are formed by weaving yarns made of elastic yarn so that the stitches are provided, the vine portions of the spectacles are alternately inserted into a plurality of stitches. The eyeglass band can be easily attached to the eyeglasses.

  In addition, stitches made of elastic yarn can be easily expanded or reduced in size, so that vines of various thicknesses and shapes can be inserted into this stitch, and the spectacle band can be attached to all types of glasses. Can be installed.

  The length of the spectacle band that connects the vines is uniquely determined by the position of the stitch that penetrates the vines, so that the most suitable force for pressing the glasses on the face without impairing the feeling of wearing. And the length once determined does not change, and readjustment is unnecessary.

  Therefore, it is possible to provide a spectacle band that can be attached to all kinds of spectacles, has a good feeling of wear, and can be easily adjusted and attached / detached while wearing.

  The spectacle band (10) of one embodiment of the present invention shown in FIG. 1 is used when the spectacles (12) are worn by attaching the vines (14) of the spectacles (12) to each other. Locked to the back of the person, and the glasses (12) are fixed by crimping so that they do not deviate from the wearing position of the face, and the entire band including both ends (10a) is made of elastic yarn (16) Is knitted in a braid shape so that a stitch (18) is provided.

  Here, the yarn (16) may be composed only of elastic yarn, natural fiber such as cotton and silk, regenerated fiber such as rayon, cupra, polynosic and lyocell, half of acetate and the like. It may be configured by combining at least one of non-elastic yarns made of synthetic fibers, synthetic fibers such as polyester, nylon, acrylic and polypropylene, and elastic yarns. In other words, if the yarn (16) contains elastic yarn and the stitch (18) formed by knitting it can sufficiently expand and contract, yarn other than elastic yarn can be mixed in the yarn (16). Good. In addition, by combining the elastic yarn and a yarn other than the elastic yarn, for example, by constituting the yarn (16) with the elastic yarn and the cotton yarn, the spectacle band (10) is given water absorbency, and the wearing feeling is given. It is also possible to give the eyeglass band (10) the function of a thread other than the elastic thread to be combined so that it can be improved.

  The elastic yarn constituting the yarn (16) includes polyurethane elastic yarn, natural rubber yarn, synthetic rubber yarn, woolly yarn, etc., and at least one of these yarns constitutes the yarn (16). ing. As will be described later, from the viewpoint of engagement between the spectacle band (10) and the vine portion (14), among these elastic yarns, rubber elasticity such as polyurethane elastic yarn, natural rubber yarn and synthetic rubber yarn is used. It is particularly preferable to use an elastic yarn having a large frictional resistance.

  The thickness (fineness) of the elastic yarn constituting the yarn (16) is determined in consideration of the physical properties of the spectacle band (10) and the wearing feeling during use, and may be approximately 10,000 dtex or less. Preferably, it is 4,000 dtex or less. When the fineness of the elastic yarn is greater than 10,000 dtex, the yarn (16) made of elastic yarn has a rough surface and the spectacle band (10) is locked to the back of the head and used. This is because the feeling of wearing becomes worse. Note that the physical properties (thickness, strength, etc.) of the obtained yarn (16) are suitable for the spectacle band (10) by freely combining the thickness and number of elastic yarns constituting the yarn (16). Can be a thing.

  Further, the elastic yarn constituting the yarn (16) may contain an additive such as titanium oxide or zinc oxide, and the form thereof is a yarn that can be produced by a stringing machine described later ( As long as it can constitute 16), it may be any of spun yarn or filament yarn. When the elastic yarn is a filament yarn, it may be either a single yarn or a twisted yarn obtained by twisting a plurality of single yarns.

  Furthermore, the elastic yarn may be bare yarn, natural fiber such as cotton and silk, regenerated fiber such as rayon, cupra, polynosic and lyocell, semi-synthetic fiber such as acetate, polyester, nylon, acrylic and polypropylene, etc. It may be a covering yarn coated with other fibers such as synthetic fibers.

  Next, in order to manufacture the eyeglass band (10) of the present embodiment using the above-described yarn (16), a braided fabric may be knitted by hand, but a normal round punching (not shown) Mass production is possible by using a string machine.

  In order to manufacture the spectacle band (10) with a round punching string machine, after winding the above-described yarn (16) on a wooden pipe for a stringing machine using a pipe winding machine and creating the necessary number of pipes By supplying the wound yarn (16) to the round stringing machine, the eyeglass band (10) knitted into a braid can be manufactured.

  Here, it is preferable that the number of hits of the eyeglass band (10) knitted in a braided shape is such that the stitches (18) are rough, such as 8 or 16 shots. This is because, if the stitch (18) of the spectacle band (10) is rough, the vine portion (14) of the spectacles (12) can be easily inserted into the stitch (18).

  Further, when weaving the spectacle band (10) with a stringing machine, it is preferable to do the knitting without supplying the core yarn. This is because if the core yarn is in the eyeglass band (10) knitted in a braid shape, it becomes an obstacle when the vine portion (14) is inserted into the stitch (18).

  In order to wear the spectacle band (10) manufactured as described above, the vine portion (14) of the spectacles (12) is alternately arranged on a plurality of stitches (18) on both ends (10a) of the spectacle band (10). The spectacle band (10) can be easily attached to the spectacles (12) simply by inserting and connecting the vine portions (14) with the spectacle band (10).

  In this case, since the stitches (18) provided at both ends (10a) are constituted by the yarn (16) made of elastic yarn, the size thereof is easily expanded or reduced. Therefore, the vine portion (14) having various thicknesses and shapes can be inserted into the stitch (18), and thus the spectacle band (10) can be attached to all kinds of spectacles.

  Here, when an elastic yarn having a high elastic coefficient such as polyurethane elastic yarn, natural rubber yarn and synthetic rubber yarn is used as the elastic yarn constituting the yarn (16), the stitch (18) is inserted into the yarn. High friction is generated with the vine portion (14) of the spectacles (12), and the spectacle band (10) can be prevented from coming off from the vine portion (14) of the spectacles (12). This friction is also exerted when water intervenes.For example, when the user sweats due to intense luck or work, the spectacle band (10) gets wet, or it is used in an environment that gets wet such as marine sports. Even in this case, it is possible to prevent the spectacle band (10) from being detached from the vine portion (14) of the spectacles (12).

  In addition, the length of the eyeglass band (10) that connects the vines (14) can be adjusted simply by adjusting the position of the stitches (18) that penetrate the vines (14) without using an adjustment tool. It is possible to adjust the pressing force of the glasses (12) to the face to the most suitable state without impairing the wearing feeling.

  And since the length of the spectacle band (10) connecting the vine parts (14) is uniquely determined by the position of the stitch (18) penetrating the vine part (14), the vine part (14) The length once determined does not change unless the position of the stitch (18) through which the thread is inserted is changed. Therefore, for example, even when the spectacles (12) wearing the spectacle band (10) are removed from the face and worn again, the length of the spectacle band (10) connecting the vine parts (14) does not change, Since the crimping force does not change, readjustment is unnecessary.

  In the above-described embodiment, the spectacle band (10) has a structure in which the yarn (16) made of elastic yarn is knitted in a braided shape, but the stitches are formed at both ends (10a) of the spectacle band (10). As long as (18) is provided, the structure may be any structure. As shown in FIG. 2, a yarn (16) made of elastic yarn is knitted, garter knitting or chain knitting not shown. It may be a thing etc. Further, in order to facilitate the penetration of the vine portion (14) into the stitch (18), the yarn (16) made of elastic yarn is knitted in a mesh shape so that the stitch (18) becomes larger. May be.

  Further, the spectacle band (10) is shown by knitting the yarn (16) made of elastic yarn as a whole, but as shown in FIG. 3, only the both ends (10a) of the spectacle band (10) are shown. May be configured by knitting a yarn (16) made of elastic yarn, and the other part that is locked to the back of the user may be configured by a strip-like elastic or inelastic member (20). . However, as described above, if the spectacle band (10) has a structure in which the entire thread (16) made of elastic yarn is knitted, the spectacle band (10) is worn when wearing spectacles (12). The air permeability of the back of the user to which the spectacle band (10) is locked can be ensured, and the wearing feeling can be improved.

It is a perspective view which shows the spectacles band of one Example of this invention. It is a front view which shows the principal part of the spectacles band of the other Example of this invention. It is a perspective view which shows the spectacles band of the other Example of this invention. It is a perspective view which shows the conventional spectacles band.
