Description

  The present invention relates to a dustproof device for spectacles which is detachably attached to spectacles, and in particular, a dustproof function such as protecting eyes from pollen while wearing spectacles (prescription glasses) which are always used. The present invention relates to a dustproof device for spectacles that can be effectively and inexpensively performed.

  2. Description of the Related Art Conventionally, various dustproof glasses have been proposed to protect eyes from dust, flying, wind pressure, and the like, in addition to pollen (see, for example, Patent Documents 1 and 2).

  As shown in FIG. 3, for example, the conventionally proposed and practically used dust-proof glasses 2 are fitted as eyeglasses by themselves, and have curved ear hooks for engaging with the ears so that they can be fixed to the face. This is a configuration including a temple 21 having Here, for those who use spectacles (particularly a problem with prescription spectacles), in order to wear the dust-proof spectacles 2 to protect the eyes from pollen and the like, the prescription spectacles used It is necessary to further attach the dust-proof glasses 2 from above, or to remove the prescription glasses being used before attaching the dust-proof glasses 2.

  However, when the dust-proof glasses 2 are further worn over the prescription glasses, the temple of the prescription glasses and the temple 21 of the dust-proof glasses 2 overlap with each other. There is a problem that the dust-proof function is impaired because the dust-proof function is likely to come off or to be displaced without being closely attached. In addition, since the prescription glasses and the dust-proof glasses 2 are separate bodies and are not interlocked with each other, it is difficult to adjust the mounting position of each other, so that a wide gap is easily generated between the dust-proof glasses 2 and the face. As a result, there is a problem that the dustproof function is impaired. If the front frame 22 of the dust-proof glasses 2 is excessively pressed against the face in order to suppress such deterioration of the dust-proof function as much as possible, the prescription glasses are also excessively pressed against the face, resulting in an increased feeling of oppression. There is also a problem of giving discomfort to the person.

  On the other hand, when the dustproof glasses 2 are attached after removing the prescription glasses used, although the above problem does not occur, it is not practical because it naturally causes a problem of a decrease in visual acuity. A configuration in which the dust-proof glasses 2 themselves are prescription glasses can be considered, but there is a problem that the cost is increased.

  Therefore, it is desired to propose a spectacle dust protector which can be detachably attached to spectacles (prescription spectacles) which are always used.

  Here, so-called hanging glasses have been conventionally proposed as having a configuration that can be detachably attached to the glasses (for example, see Patent Document 3).

However, such a pair of eyeglasses is proposed for the purpose of obtaining a state of wearing sunglasses, or for the purpose of correcting vision of prescription glasses, and can be detachably attached to the eyeglasses. However, it does not exert any dustproof function on the glasses.

  The present invention has been made in order to solve the problems of the related art, and it has been proposed to protect eyes from pollen while wearing spectacles (particularly, prescription glasses) which are always used. It is an object of the present invention to provide a spectacle dust protector capable of effectively and inexpensively performing a dustproof function.

  In order to solve the problem, the present invention is a spectacle dust remover that is detachably attached to the spectacles, in a state attached to the spectacles, respectively positioned behind the left and right lenses of the spectacles, A pair of left and right cylindrical members at least a rear peripheral portion of which is formed of an elastic body, a telescopic connecting member that connects the pair of left and right cylindrical members to each other, and attached to each of the pair of left and right cylindrical members, And a holding member for holding a pair of left and right pads of the eyeglasses.

  ADVANTAGE OF THE INVENTION According to the spectacles protective device for eyeglasses which concerns on this invention, in the state attached to the spectacles (especially suitable for prescription spectacles), a pair of left and right positioned respectively behind the left and right lenses of the spectacles Therefore, when the spectacles to which the spectacles for spectacles are attached are worn, the surroundings of the eyes are covered by the lens of the spectacles and the cylindrical member, and a dustproof function is achieved. Here, since at least the rear peripheral portion (the portion that comes into contact with the face portion) of the tubular member is formed of an elastic body, the adhesion to the face portion is enhanced, and the dustproof function can be improved, and the use of the tubular member can be improved. Has the advantage that the user is less likely to feel uncomfortable. Further, an elastic connecting member for connecting the pair of left and right cylindrical members to each other, and a holding member attached to each of the pair of left and right cylindrical members to hold the pair of left and right pads of the glasses. Therefore, the dustproof device for spectacles is attached to the spectacles by expanding and contracting the connecting member, adjusting the position of the tubular member and thus the holding member, and holding the pad with the holding member. Therefore, the spectacles and the attached dustproof device for eyeglasses are linked to each other, so that the mounting position can be easily adjusted (just to adjust the mounting position of the spectacles), and the eyeglass dustproof device itself is fixed to the face. Since there is no need for a temple for performing the operation, there is an advantage that the dustproof function is not impaired. In addition, since it is sufficient to keep the glasses on, there is no need to attach a prescription lens to the cylindrical member, and there is an advantage that the cost is low. Furthermore, since the position of the cylindrical member and the holding member can be adjusted by expanding and contracting the connecting member, the shape of the front frame of the glasses (Wellington, Boston, Square, Oval, Lloyd, etc.) is not necessarily independent. There is also the advantage that there is no need to prepare eyeglass dust protectors and the degree of freedom is high. In other words, the cylindrical member is formed so as to have a smaller cross-sectional dimension than the eyeglasses having the smallest lens size among the various eyeglasses to be attached, and the expansion and contraction range of the connecting member is set between the left and right lenses of the various eyeglasses. If it is set so as to be compatible with the variation range of the distance, it suffices to prepare only one kind of spectacles for spectacles for all spectacles to be attached. Therefore, it is economical for the spectacle user, especially when having a plurality of spectacles, without having to purchase a plurality of spectacle dust protectors for each spectacle. Has the advantage that there is no need to stock a plurality of types of spectacles for eyeglasses, and the time and effort for inventory management can be reduced. In addition, according to the spectacles dust protector according to the present invention, since the circumference of the eye is covered by the lens and the cylindrical member of the spectacle, it is easy to hold the humidity in the covered space, and to prevent the eye from drying in winter. It is also possible to aim.

Therefore, the spectacles and the attached spectacle dust protector are linked to each other, so that the mounting position can be easily adjusted. In addition, since the spectacle spectacle itself does not require a temple for fixing to the face, a dustproof function is provided. Is not impaired. In addition, since it is sufficient to keep the glasses on, there is no need to attach a prescription lens to the cylindrical member, and there is an advantage that the cost is low. Furthermore, since the positions of the cylindrical member and the holding member can be adjusted by expanding and contracting the connecting member, it is not necessary to prepare a separate dustproofing device for the glasses for each shape of the front frame of the glasses. Is also high. In other words, the cylindrical member is formed so as to have a smaller cross-sectional dimension than the eyeglasses having the smallest lens size among the various eyeglasses to be attached, and the expansion and contraction range of the connecting member is set between the left and right lenses of the various eyeglasses. If it is set so as to be compatible with the variation range of the distance, it suffices to prepare only one kind of spectacles for spectacles for all spectacles to be attached. Therefore, it is economical for the spectacle user, especially when having a plurality of spectacles, without having to purchase a plurality of spectacle dust protectors for each spectacle. Has the advantage that there is no need to stock a plurality of types of spectacles for eyeglasses, and the time and effort for inventory management can be reduced. In addition, according to the spectacles dust protector according to the present invention, since the circumference of the eye is covered by the lens and the cylindrical member of the spectacle, it is easy to hold the humidity in the covered space, and to prevent the eye from drying in winter. It is also possible to aim.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a diagram showing a schematic configuration of a spectacle dust protector according to an embodiment of the present invention, wherein (a) is a front view, (b) is a plan view, and (c) is a spectacle dust protector. The enlarged view of the connection member provided is each shown. FIG. 2 is a rear view schematically showing a state in which the spectacles for eyeglasses according to the present embodiment is attached to the eyeglasses. As shown in FIGS. 1 and 2, the spectacles dust protector 1 according to the present embodiment is attached to the spectacles (prescription glasses) 3 (the state shown in FIG. 2). A pair of left and right cylindrical members 11 and 12 which are located behind the lenses 31 and 32 (on the front side of the paper surface of FIG. 2) and at least the rear edge of which is formed of an elastic body, and a pair of left and right cylindrical members 11 and 12 are formed. A telescopic connecting member 13 connected to each other, and holding members 14 and 15 attached to each of the pair of left and right cylindrical members 11 and 12 for holding the pair of left and right pads 33 and 34 of the glasses 3. Have.

  More specifically, the tubular member 11 according to the present embodiment includes an annular member 111 formed of a material having rigidity, and an elastic member 112 extending rearward from a peripheral edge of the annular member 111. ing. Similarly, the tubular member 12 also includes an annular member 121 formed of a material having rigidity, and an elastic member 122 extending rearward from a peripheral edge of the annular member 121. Both ends of the connecting member 13 are attached to the upper edges of the annular members 111 and 121, respectively. For example, when the connecting member 13 is made of metal and the annular members 111 and 121 are made of resin, both ends of the connecting member 13 are hooked. It is possible to adopt a method in which both ends of the hook shape are fitted into holes (not shown) provided on the upper edges of the annular members 111 and 121 and caulked. The holding members 14 and 15 are attached to inner edges of the annular members 111 and 121, respectively. As a method of attaching the holding members 14, 15 and the annular members 111, 121, for example, a method of bonding them with an adhesive can be adopted. The annular members 111 and 121 can be formed from various materials having rigidity, but are preferably formed from a polycarbonate resin, an acrylic resin, or the like because they are preferably easy to mold. Further, the elastic members 112 and 122 can be formed from various elastic materials such as hard rubber, sponge rubber, and silicone rubber. The annular members 111 and 121 and the elastic members 112 and 122 are joined to each other using an adhesive, or a groove is formed at a position facing the peripheral edge of the annular members 111 and 121 of the elastic members 112 and 122. Then, the annular members 111 and 121 may be connected to each other by fitting them into the grooves.

  The connecting member 13 according to the present embodiment is made of metal, and has a base end fixed to the upper edge of the annular member 111 and extends toward the annular member 121 as shown in FIG. An arm member 131, a substantially rectangular support frame 132 extending in the axial direction of the arm member 131, a shaft 133 whose base end is fixed to the upper edge of the annular member 121 and extends toward the annular member 111, A coil spring 134 is provided between the shaft 132 and the shaft 133.

  The substantially rectangular support frame 132 includes guide rods 132a and 132b arranged in parallel in front and rear, and connecting pieces 132c and 132d for connecting the base ends and the distal ends of the guide rods 132a and 132b to each other. The tip of the arm member 131 is connected to the connecting piece 132c.

  A shaft 133 is inserted into the connecting piece 132d through an insertion hole (not shown) provided at a substantially central portion thereof. Further, a sliding piece 135 that is guided by the guide rods 132a and 132b and slides is attached to the distal end of the shaft rod 133. More specifically, the sliding piece 135 is provided with guide holes (not shown) at both ends thereof, and the guide rods 132a and 132b are inserted into the guide holes.

  The coil spring 134 is interposed between the sliding piece 135 and the connecting piece 132d with the shaft 133 inserted.

  According to the connecting member 3 having the above configuration, the coil spring 134 is compressed between the sliding piece 135 and the connecting piece 132d by pulling the pair of left and right tubular members 11 and 12 away from each other. Thus, an urging force acts in a direction in which the pair of left and right cylindrical members 11 and 12 approach each other. Therefore, if the pads 33 and 34 are positioned between the holding members 14 and 15 after the tubular members 11 and 12 are pulled so that the holding members 14 and 15 are separated from each other by more than the separation distance between the pads 33 and 34, It is possible to reliably hold the pads 33 and 34 by the urging force.

  As described above, the pair of left and right cylindrical members 11, which are located behind the left and right lenses 31, 32 of the spectacles 3, respectively, when the spectacles dust protector 1 according to the present embodiment is attached to the spectacles 3, Since the eyeglasses 12 are provided, when the eyeglasses 3 to which the eyeglass dustproof device 1 is attached are worn, the surroundings of the eyes are covered by the lenses 31 and 32 of the eyeglasses and the tubular members 11 and 12, and a dustproof function is achieved. Here, since at least the rear peripheral portions (elastic members 112 and 113 in the present embodiment) of the tubular members 11 and 12 are formed of an elastic body, the adhesion to the face is enhanced and the dustproof function is improved. And the user is less likely to feel uncomfortable. The pair of left and right tubular members 11 and 12 are attached to each of the pair of left and right tubular members 11 and 12 so that the pair of left and right tubular members 11 and 12 are connected to each other. In order to provide the holding members 14 and 15 for holding, the connecting members 13 are expanded and contracted to adjust the positions of the tubular members 11 and 12 and thus the holding members 14 and 15, and the pads 33 and 34 are held by the holding members. By nipping at 14 and 15, the spectacles dust protector 1 is attached to the spectacles 3. Therefore, the spectacles 3 and the attached dustproof device 1 for eyeglasses work together, so that the mounting position can be easily adjusted (just adjust the mounting position of the spectacles 3). Since a temple for fixing to the face is unnecessary, there is an advantage that the dustproof function is not impaired. In addition, since the eyeglasses 3 can be left as they are, there is no need to attach a prescription lens to the cylindrical members 11 and 12, which is advantageous in that it is inexpensive.

In addition, since the positions (separation distances) of the tubular members 11 and 12 and the holding members 14 and 15 can be adjusted by expanding and contracting the connecting member 13, the shape of the front frame of the glasses 3 (Wellington, Boston, Square) is not necessarily required. , Oval, Lloyd, etc.), it is not necessary to prepare a separate dustproofing device 1 for a spectacle. In other words, the cylindrical members 11 and 12 (the annular members 111 and 121) are formed so as to have a smaller cross-sectional dimension than the eyeglasses having the smallest lens size among the various eyeglasses 3 to be attached, and the connecting member 13 If the expansion and contraction range is set so as to match the fluctuation range of the distance between the left and right of the lenses 31 and 32 of the various eyeglasses 3, one kind of eyeglass dustproof device 1 can be used for all the eyeglasses 3 to be attached. You just need to prepare. Therefore, it is not necessary for the spectacle user to purchase a plurality of spectacle dust protectors 1 for each spectacle 3, especially when the user has a plurality of spectacles 3. For the seller, there is an advantage that it is not necessary to stock a plurality of types of dustproof equipment 1 for glasses, and the trouble of inventory management can be reduced. Furthermore, in the present embodiment, the tubular members 11 and 12 include the annular members 111 and 121 formed of a hard material, and the connecting member 13 is attached to the annular members 111 and 121. When the positions of the tubular members 11 and 12 are adjusted by the levers, there is also an advantage that the shapes of the tubular members 11 and 12 are easily held and the attachment is easy.

  In addition, the spectacle dustproof implement 1 according to the present embodiment is formed of a transparent material, and includes spectacle members 16 and 17 that close the front openings of the tubular members 11 and 12. The spectacle members 16 and 17 can be formed from various materials as long as they are transparent, and are formed from, for example, a polycarbonate resin or an acrylic resin. Since the spectacle dustproof device 1 according to the present embodiment includes the spectacle members 16 and 17 that close the front openings of the cylindrical members 11 and 12, for example, the lenses 31 and 32 of the spectacles 3 and the cylindrical members 11 and 12 Even if a gap is formed between the front ends (annular members 111 and 121), pollen and dust do not enter the inside of the tubular members 11 and 12 from the front openings of the tubular members 11 and 12. It is possible to further improve the dustproof function. Moreover, since the spectacle members 16 and 17 are formed from a transparent material, the visibility of the spectacles 3 is not impaired.

  Further, in the holding members 14 and 15 according to the present embodiment, the surfaces of the spectacles 3 facing the pair of left and right pads 33 and 34 are formed in an uneven shape. Therefore, when the pads 33, 34 are held, the frictional resistance between the pads 33, 34 and the holding members 14, 15 increases, and the positions of the holding members 14, 15 with respect to the pads 33, 34 are shifted. This makes it difficult for the eyeglass dustproof device 1 to be displaced from the eyeglasses 3, and it is possible to secure the attachment.

  Furthermore, the tubular members 11 and 12 according to the present embodiment are protruded outwardly or inwardly (inwardly in the present embodiment) from the rear peripheral edges 11a and 12a in a planar shape, and are elastic members. Are provided. In other words, the elastic members 112 and 122 include the flat flange portions 112a and 122a. Therefore, when the spectacles 3 to which the spectacles for spectacles 1 according to the present embodiment is attached are worn, the face portions come into contact with the flange portions 112a and 122a projecting in a planar shape. That is, since the spectacles 1 for eyeglasses and the face come into surface contact with the flanges 112a and 122a, the adhesion to the face is enhanced, and the dustproof function can be further improved. Is more difficult to feel.

  Note that it is preferable to adopt a configuration in which an adhesive is attached to the front peripheral portion of the tubular members 11 and 12 (annular members 111 and 121). According to such a configuration, if the adhesive is pressed against the rear surfaces of the lenses 31 and 32 of the eyeglasses 3 when the eyeglass dustproof device 1 is attached to the eyeglasses 3, the cylindrical members 11 and 12 are pressed by the adhesive force of the adhesive. Is firmly fixed to the rear surfaces of the lenses 31 and 32. As the adhesive, for example, a polyurethane resin having re-adhesiveness can be suitably used.
