Description

  The present invention relates to an improvement in a glasses case that houses and protects the glasses when the glasses are not used.

  As a glasses case for storing and protecting the glasses when the glasses are not used, a hard case type (for example, connecting a housing (lower lid) and a lid (upper lid) made of metal or synthetic resin with a hinge (for example, Patent Documents 1 to 3) and a bag-shaped or ring-shaped soft case type made of a flexible material such as leather, vinyl, or cloth (for example, refer to Patent Documents 4 and 5).

Japanese Patent Laying-Open No. 2004-202125 (FIG. 1) Registered Utility Model No. 3104058 (FIGS. 1 and 4) Japanese Utility Model Publication No. 4-74029 (FIGS. 1, 2, and 4) JP 2004-129901 A (FIGS. 2-4 and 11) JP 2004-733338 A (FIGS. 1-3)

  The hard case type has high protection performance for the contained glasses. However, since the case is large and bulky with respect to the size of the glasses, there is a problem in that it becomes an obstacle when carrying. Further, there is a problem that the glasses cannot be stably held in the case unless a thick cushioning material or the like is accommodated in the case. Furthermore, there is a problem that the cost is increased because the structure is relatively complicated. Furthermore, since it is necessary to open the lid (upper lid) when putting in and out the glasses, there is a problem that the glasses cannot be easily put in and out.

  In addition, the soft case type is not bulky and is convenient to carry, has a relatively simple structure, can reduce costs, and is relatively easy to put in and out of glasses. However, there is a problem that the protection performance of the glasses, which is the basic performance of the glasses case, is low.

  The present invention has been made to solve the above-described problems, and achieves ease of carrying, ease of putting in and out of glasses, and cost reduction while maintaining high protection performance of glasses. It is an object to obtain a highly practical glasses case that can be used.

  In order to solve the above problems, the glasses case according to the present invention comprises a top plate and a bottom plate that are spaced apart from each other and are substantially opposed to each other, and a connecting plate that connects the rear ends of the top plate and the bottom plate. It is provided between the opened case body that is substantially U-shaped in the left and right side view, and the top plate and the bottom plate, and the gap between the top plate and the bottom plate can be switched between a narrow interval state and a wide interval state where the interval is wide. Switching means, holding the glasses in the case body in the narrow interval state, and putting in and out the glasses from the left and right side openings of the case body in the wide interval state.

  Here, in the narrow space state, it is preferable that the switching means is interposed between the top plate and the bottom plate so as to suppress the space from being narrowed.

  Moreover, it is preferable that the main elastic deformation part of the said case main body for setting it as the said narrow space state or a wide space state is the said connection board.

  Further, it is preferable that the top plate is inclined so as to descend from the center in the left-right direction to the left and right.

  Furthermore, the front portion of the top plate is inclined so as to descend as it goes forward, and the case body is formed so that the amount of elastic deformation increases as it approaches the wide gap state from the narrow gap state. The switching means is a swinging member provided with a contact part that contacts the lower surface of the top plate at the upper part, and a lower part supported on the front part of the bottom plate so as to be swingable about a left-right axis, The narrow spacing state occurs when the swinging member swings rearward, and the wide spacing state occurs when the swinging member swings forward and the contact portion contacts the lower surface of the top plate. This is preferable.

  In addition, the front portion of the top plate is inclined so as to descend as it goes forward, and the case body is formed so that the amount of elastic deformation increases as it approaches the wide interval state from the narrow interval state. The switching means is provided with a contact portion that contacts the lower surface of the top plate at the upper portion, and the lower portion is a slide member supported by the front portion of the bottom plate so as to be slidable back and forth, and the slide member slides backward. In this state, it is preferable that the narrow interval state is established, the slide member slides forward, and the contact portion contacts the lower surface of the top plate to enter the wide interval state.

  Further, it is preferable that a front side portion of the top plate in the left-right direction is cut out in the front-rear direction, and the upper portion of the swing member or the slide member is protruded outward from the cut-out portion to form an operation portion.

  According to the glasses case according to the present invention, the left and right side surfaces having a front surface opened, comprising a top plate and a bottom plate that are substantially spaced apart from each other, and a connecting plate that connects rear ends of the top plate and the bottom plate. A substantially U-shaped case body, and a switching means provided between the top plate and the bottom plate and capable of switching between a narrow interval state where the interval between the top plate and the bottom plate is narrow and a wide interval state where the interval is wide. The glasses are held in the case body in the narrow interval state, and the glasses are put in and out from the left and right side openings of the case body in the wide interval state, so the glasses are held by the substantially opposite top and bottom plates. Therefore, the protection performance of the glasses can be maintained at a high level, and it is not bulky so that it does not get in the way when carried. Further, the glasses can be easily put in and out from the left and right side openings of the case body. Furthermore, with a simple configuration, the cost can be reduced and the design can be improved.

  Further, in the narrow space state, when the switching means is interposed between the top plate and the bottom plate so as to suppress the narrowing of the space, the glasses stored between the top plate and the bottom plate The protection performance can be further improved.

  Further, when the main elastic deformation part of the case body for making the narrow interval state or the wide interval state is the connecting plate, for example, the longitudinal elastic modulus of the top plate and the bottom plate is increased or the sectional moment of inertia is increased. Since the rigidity and strength of the top plate and the bottom plate can be increased by increasing the size, the protection performance of the glasses accommodated between the top plate and the bottom plate can be further improved.

  Furthermore, when the top plate is tilted so as to descend from the center in the left-right direction to the left and right, the top plate follows the shape of the glasses and the left and right side openings in the narrow space state become smaller. Therefore, the glasses can be held more stably and reliably.

  In addition, the front portion of the top plate is inclined so as to descend as it goes forward, and the case body is formed so that the amount of elastic deformation increases as it approaches the wide interval state from the narrow interval state. The switching means is provided with a contact portion that contacts the lower surface of the top plate at the upper portion, and a lower portion is a swing member that is supported on the front portion of the bottom plate so as to be swingable about a left-right axis, When the swinging member swings backward, the narrow spacing state occurs, and when the swinging member swings forward and the contact portion contacts the lower surface of the top plate, the wide spacing state occurs. When the rocking member is swung forward, the abutment portion is in contact with the lower surface of the top plate, and a restoring force of elastic deformation of the case body acts on the corresponding contact portion, so that the contact The state is maintained and the wide interval state is established, and the eyeglasses can be taken in and out. Can. After the eyeglasses are put in and out, the swinging member easily swings backward by the restoring force, so that the narrow space can be easily set. With such a configuration, the configuration of the eyeglass case including the case main body and the swing member is further simplified, and thus the cost can be further reduced.

  Further, the front portion of the top plate is inclined so as to descend as it goes forward, and the case body is formed so that the amount of elastic deformation increases from the narrow interval state toward the wide interval state. The switching means is provided with a contact portion that contacts the lower surface of the top plate at the upper portion, and the lower portion is a slide member supported by the front portion of the bottom plate so as to be slidable back and forth, and the slide member slides backward. When the slide member is slid forward, the slide member is slid forward, and when the contact portion is in contact with the lower surface of the top plate, the slide member is slid forward. In a state where the contact portion is in contact with the lower surface of the top plate, a restoring force of the elastic deformation of the case body acts on the corresponding contact portion, and the contact state is maintained to be in the wide interval state. The value of the out put can be carried out. Then, after the eyeglasses are put in and out, the slide member easily slides back by the restoring force, so that the narrow space can be easily set. With such a configuration, the configuration of the eyeglass case including the case body and the slide member becomes simpler, and thus the cost can be further reduced.

  Furthermore, when the front part of the center part in the left-right direction of the top plate is notched in the front-rear direction, and the upper part of the swinging member or slide member is projected outward from the notch part, the operation part is moved forward. Since it can be easily set to the wide interval state by operating, the operability for putting in and out the glasses can be improved.

It is curved so as to descend. In addition, you may make it incline linearly so that the front side part of the top plate 3 may fall as it goes ahead. Accordingly, the case body 2 is formed so that the amount of elastic deformation increases as the narrow space state N approaches the wide space state W. As shown in FIGS. When the case body 2 is elastically deformed from the interval state N to the wide interval state W, the glasses G can be put in and out from the left and right side surface openings S and S.

  Here, the top plate 3, the bottom plate 4 and the connecting plate 5 constituting the case body 2 are formed by selecting materials, thicknesses and the like so as to have desired strength and rigidity. The top plate 3, the bottom plate 4 and the connecting plate 5 are made of, for example, a plastic material such as polyacetal, polypropylene, nylon or ABS, or a base material such as epoxy resin, polybutylene terephthalate or polyacetal, which is reinforced with carbon fiber, glass fiber or aramid fiber. However, the top plate 3, the bottom plate 4, and the connection plate may be used separately.

  In the present embodiment, as shown in FIGS. 1, 2, and 6, the thickness of the connecting plate 5 of the case body 2 is made thinner than the thickness of the top plate 3 and the bottom plate 4, and the case body 2 is made wider than the wide plate. The bending rigidity of the connecting plate 5 that resists the external force that causes the spacing state W is set to be smaller than the bending rigidity of the top plate 3 and the bottom plate 4 so that the main elastic deformation portion of the case body 2 is the connecting plate 5. It is composed. Therefore, for example, the longitudinal elastic modulus of the top plate 3 and the bottom plate 4 can be increased or the moment of section can be increased to increase the rigidity and strength of the top plate 3 and the bottom plate 4. The protection performance of the glasses G accommodated between the two can be further improved.

The upper part and the front part of the swinging member 7 protrude outward from a notch 3a in which the front side portion of the central portion 3 in the left-right direction is notched in the front-rear direction, and the upper part of the swinging member 7 serves as the operation part 16. Therefore, since the wide gap state W can be easily achieved by operating the operation unit 16 forward, the operability for putting in and out the glasses G can be improved.

  When the operating member 16 is operated forward from the narrow interval state N shown in FIG. 6A to swing the swing member 7 forward, the contact pin 10 is in contact with the lower surface of the top 3. , The restoring force of the elastic deformation of the case main body 2 acts on the abutment pin 10 to maintain the abutment state, so that the wide interval state W shown in FIG. G can be put in and out. Then, after the eyeglasses G are put in and out, the swinging member 7 easily swings backward by the restoring force, so that the narrow space state N shown in FIG. With such a configuration, the configuration of the glasses case 2 including the case main body 2 and the swing member 7 becomes simpler, and the cost can be further reduced.

  In the narrow space state N shown in FIG. 6 (a), the stopper 7c of the swing member 7 is stopped against the upper surface of the bottom plate 4, and the swing of the swing member 7 to the rear is restricted. In the wide interval state W shown in FIG. 5B, the stopper 7d of the swing member 7 is stopped against the upper surface of the bottom plate 4 and the swing of the swing member 7 forward is restricted. In the narrow interval state N, the contact pin 10 which is the contact portion 9 of the swinging member 7 whose rearward swing is restricted contacts the lower surface of the top plate 3. A swing member 7 is interposed between the top plate 3 and the bottom plate 4 so as to suppress the interval from becoming narrow. Therefore, the protection performance of the glasses G accommodated between the top plate 3 and the bottom plate 4 can be further improved.

Therefore, the protection performance of the glasses G is further improved. The cushioning material 15 may be affixed by separating a plurality of cushioning materials only on a part of the inner surface side of the case body 2. For example, the structure which affixes the buffer material 15 only on the inner surface side of the top plate 3 and the bottom plate 4 may be sufficient.

  As shown in FIG. 3, the top plate 3 has a shape that curves so as to descend from the center in the left-right direction to the left and right, and the glasses G that are formed to curve in accordance with the shape around the human eyes. The shape is matched. Therefore, the top plate 3 follows the shape of the glasses G and the left and right side openings S, S in the narrow gap state N become smaller, so that the glasses G can be held more stably and reliably. Further, as shown in FIG. 1, in the narrow gap state N, the swinging member 7 is inserted between the left and right nose pads of the glasses G, so that the glasses G are held more stably and reliably.
