Description of symbols is omitted.

Next, the present invention will be described with respect to two embodiments. A rotation support mechanism (hereinafter referred to as "rotation support mechanism") 10 for the splash prevention plate of the first embodiment is, for example, as shown in FIG. When the splash prevention plate S is attached to the spectacles G and used, it is used by being interposed between the spectacles G and the splash prevention plate S. In the form shown in FIG. 1, a rotation support mechanism 10 is incorporated in an attachment for attaching a splash prevention plate (hereinafter referred to as "attachment") 1 attached to eyeglasses G. As shown in FIG. The attachment 1 is positioned in front of the user's ears during use (see FIGS. 8 and 9). This attachment 1 can be marketed alone.

A single attachment 1 is shown in FIG. The attachment 1 of the present embodiment is attachable to and detachable from the eyeglasses G, more specifically, the temple G1 of the eyeglasses as a rod-shaped member of the hook member. Since it is detachable, it is possible to easily support the splash prevention plate S using a hooking member such as eyeglasses G. For this attachment and detachment, the attachment 1 is provided with an insertion groove 111 having a space for passing the temple G1 of the spectacles. Usually, one eyeglass G has two temples G1 on the left and right sides. For this reason, as shown in FIG. 1, two attachments 1 are used for general spectacles G. FIG.

The attachment 1 has an inner portion 11 positioned on the side of the user's head when in use, and an outer portion 12 positioned on the side opposite to the head. Regarding the attachment 1, the vertical direction shown in FIG. 2 will be described below, and the inside and outside will be described with the user's head side as the inside and the side opposite to the head as the outside. The attachment 1 has a vertically elongated shape. The inner part 11 and the outer part 12 are made of resin. The inner portion 11 and the outer portion 12 are connected by a hinged opening/closing portion 13 . This hinge-type opening/closing part 13 facilitates attachment and detachment to and from the rod-shaped member (eyeglass temple G1). The closed state of the inner portion 11 and the outer portion 12 is fixed by a fixing screw 14 .

The insertion groove 111 is provided in the inner portion 11 so as to extend in the width direction of the attachment 1 . As shown in FIG. 2 , the insertion groove 111 is covered with the outer portion 12 to form a through hole in which both ends in the width direction of the attachment 1 are open. The opening/closing part 13 is provided at the upper end of the attachment 1, and has a rotation axis parallel to the extending direction of the temple G1 of the spectacles (the front-rear direction on the user's basis). By opening the opening/closing part 13 and moving the outer part 12 so as to flip up with respect to the inner part 11, the insertion groove 111 is opened, so that it can be attached to the temple G1 of the spectacles. At this time, the attachment 1 can be easily attached to the spectacles G, which is a hook member, by passing the temple G1 of the spectacles, which is a rod-shaped member, through the insertion groove 111. - 特許庁

In the inner portion 11, the surface (inner surface) facing the user's head during use is flat or gently curved as shown in FIG. For this reason, the user's head is less likely to feel uncomfortable when this surface hits the user's head. It is desirable that this inner surface be a smooth surface without irregularities.

The fixing screw 14 is configured to be screwed into the lower portion of the attachment 1 from the outer portion 12 toward the inner portion 11 . As can be seen in FIG. 1, the inner part 11 is provided with a nut into which a fixing screw 14 is screwed. A flat knurling is formed on the outer peripheral surface of the head of the fixing screw 14, so that it is difficult to slip even with bare hands, and the fixing screw 14 can be easily opened and closed by twisting.

Next, the rotation support mechanism 10 incorporated in the attachment 1 in the first embodiment will be described. The rotation support mechanism 10 has a support portion 15 that rotates and supports the splash prevention plate S on the upper side so as to open and close the splash prevention plate S by moving it toward and away from the user's face. The support portion 15 holds the splash prevention plate S at a predetermined opening degree by means of concave-convex fitting. Since the opening is maintained by fitting the projections and recesses, the splash prevention plate S may deviate from the predetermined opening due to the weight of the splash prevention plate S and the force applied to the splash prevention plate S when the user shakes his or her head. is unlikely to occur, and the opening degree of the splash prevention plate S can be reliably maintained.

The support portion 15 includes a main body 151, a rotating portion 152, and a cover 153, as partially shown in cross section in FIG. The rotating portion 152 is positioned to coincide with the center of rotation C of the splash prevention plate S, is axially supported by the outer portion 12 , and is rotatable with respect to the main body 151 . The extension direction (axial direction) of the rotation center C is along the lateral direction of the user during use. In the form shown in FIG. 4 , a substantially disk-shaped rotating portion 152 is provided inside a main body 151 . As such, the rotating portion 152 is partially surrounded by the main body 151 .

The rotating portion 152 has a plurality of fitted portions 1521 arranged in the circumferential direction of rotation. In the present embodiment, five concave portions formed to be concave in the radially inner direction are provided as the fitted portions 1521 at even intervals in the circumferential direction (every 20° angle). A convex portion 1522 is formed between the fitted portions 1521 adjacent in the circumferential direction. In this embodiment, five concave portions (to-be-engaged portions 1521) and four convex portions 1522 are repeatedly formed in the circumferential direction to form a gear shape. Between the fitted portions 1521, the projections 1522 are substantially sine-curved projections formed along the circumferential direction. Therefore, as shown in FIGS. 8 and 9, the opening degree of the splash prevention plate S can be adjusted in five steps. Since the supporting portion 15 configured in this manner holds the splash prevention plate S at a predetermined opening degree by means of concave-convex fitting, it is possible to reliably set the opening degree close to the user's request. Therefore, the splash prevention plate S can be lifted up a little and held stably, which is convenient. Also, as shown in FIGS. 9(a) and 9(b), it is possible to lift the splash prevention plate S far above the line of sight of the user.

For adjusting the degree of opening, the main body 151 has a fitting portion 1511 that applies an elastic force to each of the plurality of fitted portions 1521 and performs uneven fitting. The elastic force is exerted by the elastic deformation portion 1512 provided adjacent to the fitting portion 1511 in the circumferential direction. The main body 151 includes a fitting portion 1511 and an elastic deformation portion 1512 and is integrally formed in the circumferential direction. This integrally formed portion is made of resin. Since the elastic deformation portion 1512 is integrally formed, the structure is such that the elastic deformation portion 1512 is reliably supported by the adjacent portions in the circumferential direction. 1512 can reliably impart elastic force. The rotating portion 152 is located at a radially inner position of this integrally formed portion.

The fitting portion 1511 is formed to have a convex portion that protrudes inward from the inner peripheral surface of the elastic deformation portion 1512 . This convex portion has a curved shape, and the curvature thereof is smaller than that of the fitted portion 1521 as shown in FIG. For this reason, the fitting portion 1511 is not fitted to the far side (inner diameter position) of the fitted portion 1521, which is a concave portion, but is partially fitted to the front side (outer diameter position). Due to such a fitted state, the convex portion 1522 can get over the fitting portion 1511 with a moderate external force as the rotating portion 152 rotates. Therefore, although the splash prevention plate S can be stably held at an opening degree close to the user's desire, the opening degree can be changed without requiring a large force. In addition, since the curved surfaces of the fitting portion 1511 and the fitted portion 1521 abut against each other, looseness is less likely to occur between the main body 151 and the rotating portion 152, and the splash prevention plate S is less likely to wobble.

As shown in FIG. 4 , the fitting portion 1511 and the elastic deformation portion 1512 are positioned apart from the outer surface of the outer portion 12 . The fitting portion 1511 and the elastic deformation portion 1512 are made of resin, and are pushed by the convex portion 1522 as the rotating portion 152 rotates when the user holds the splash prevention plate S to open and close the fitting portion. 1511 and elastic deformation portion 1512 move radially outward to allow rotation of rotating portion 152 . At this time, since the convex portion 1522 of the rotating rotating portion 152 climbs over the fitting portion 1511, it is possible to give the user a click feeling, which is a tactile sensation of "clicking", and the opening degree can be changed in five stages. It is made to realize that it does.

In the stopped state of the rotating portion 152 , the fitting portion 1511 , which is a convex portion, is engaged with the fitting portion 1521 , which is a concave portion, while receiving the elastic force of the elastically deforming portion 1512 . A plurality of fitted portions 1521 of the rotating portion 152 and a fitting portion 1511 of the main body 151 are combined, and uneven fitting is performed under elastic force, so that each of the plurality of fitted portions 1521 The support portion 15 can hold the splash prevention plate S with a corresponding opening.

The concave-convex fitting is performed on the outer peripheral surface of the rotating portion 152 with the center of rotation C as a reference. Since the concave-convex fitting is performed in the circumferential direction of the rotating portion 152, the dimension in the direction of the rotating shaft is not increased due to the concave-convex fitting, so that the support portion 15 can be configured compactly especially in the inner and outer directions.

Two protrusions 1523 are formed on the outer end surface of the rotating portion 152 so as to face each other in the radial direction. As shown in FIG. 3, two holes S1 provided in the splash prevention plate S are fitted to the projections 1523. As shown in FIG.

The cover 153 is attached to the outside of the rotating portion 152 with the splash prevention plate S interposed therebetween. As shown in FIG. 1, the cover 153 is attached so as to cover both ends of the splash prevention plate S. As shown in FIG. The cover 153 is fitted and attached to the rotating portion 152 . As shown in FIG. 3 , claw portions 1524 are provided at the tips of the projections 1523 on the outside in the facing direction of the projections 1523 . Further, as shown in FIG. 5, a cover fitting portion 1531 is formed on the rear surface of the cover 153 . The cover 153 is attached by fitting the cover fitting portion 1531 to the claw portion 1524 . Since the cover 153 is fitted and attached to the rotating portion 152, attachment of the splash prevention plate S is easy.

Next, FIG. 6 shows a second embodiment. In the second embodiment, the neck hanging portion 2 is provided as a hooking member for hooking on the head of the user, and the rotation support mechanism 10 is attached to the splash prevention plate support portions 3 provided at both ends of the neck hanging portion 2. It has been incorporated. Therefore, the rotation support mechanism 10 is integrally formed with the neck hanging portion 2 . In the second embodiment, since the hooking member (neck hanging portion 2) and the rotation support mechanism 10 are integrated, a unified design can be realized. Therefore, it is possible to form a support for the splash prevention plate S with excellent design. The neck hanging part 2 abuts on the rear part of the user's neck during use. The neck hanging portion 2 can be made of various materials such as resin and metal. The rotary support mechanism 10 has a slightly different appearance, but has the same configuration as that of the first embodiment. Therefore, detailed description is omitted. It should be noted that, unlike the first embodiment, in the second embodiment, it is not necessary to divide the portion where the rotation support mechanism 10 is formed into the inner portion 11 and the outer portion 12 .
