Abstract

A nose pad having moderate cushioning in the front-rear direction and capable of being produced at low cost. In a nose pad which is supported by inserting a mounting leg protruding substantially at the center of the back side into a pad box attached to the tip of a pad arm extending from a spectacle frame. The elastic material is interposed between the base of the mounting foot and the periphery of the opening of the pad box. [Selection] Figure 1

Description

  The present invention relates to a nose pad that is one of the members of a spectacle frame, and more particularly to a nose pad that has excellent cushioning properties.

  The nose pad is a component of the eyeglass frame that touches the face of the eyeglass wearer and plays an important role in holding the eyeglass frame in the correct position. Etc. occur, the feeling of wearing is impaired, and the correction of visual acuity is also adversely affected.

In order for the nose pad to fully perform its function, it is ideal that it has moderate flexibility in itself and can swing freely in all directions, but also has cushioning properties in the front-rear direction. However, there were few nose pads that could meet this requirement. This was partly because the nose pad is a small part and not very expensive.
In addition, since it is a small part, if the number of parts is increased, the assembly becomes troublesome, there is a problem in durability, and the manufacturing cost is also increased.

  This device is intended to solve the above-mentioned conventional problems related to conventional nose pads, and has a simple structure, a nose pad that has moderate cushioning in the front-rear direction and can be produced at low cost. It is to be provided.

  In a nose pad that is supported by inserting a mounting foot protruding from the center of the back into a pad box attached to the tip of a pad arm that extends from the eyeglass frame, An elastic material such as an O-ring made of soft silicone rubber is interposed between the root and the periphery of the opening of the pad box to provide the cushioning property in the front-rear direction.

  An elastic silicone rubber O-ring is fitted at the base of the mounting foot, so if a rearward force is applied from the nose pad body surface side, the O-ring will contact the edge of the pad box opening and the nose. Cushioning is imparted to the nose pad main body by the elasticity of the O-ring. Therefore, when wearing the eyeglass frame with this nose pad attached, the nose pad comes in contact with the wearer's nose with cushioning properties, realizing excellent fit and comfort, and the eyeglass frame is normal It has the effect that it can be effectively held in position. In addition, the number of parts is small, the manufacture is easy, the appearance is not strange, and the durability is high.

The expanded longitudinal cross-sectional view of one Example of the nose pad which concerns on this device. Similarly, the enlarged cross-sectional view. Similarly, the expansion perspective view which decomposed | disassembled and drawn each of these component parts. Similarly, the expansion perspective view of the state where the O ring was inserted.

  An elastic body such as an O-ring made of silicone rubber is interposed at the base of the nose pad mounting foot, and the elastic body is sandwiched between the back surface of the nose pad and the edge of the opening of the pad box, thereby cushioning the nose pad. The biggest feature exists in the point which gave.

FIG. 1 is an enlarged longitudinal sectional view of an embodiment of a nose pad according to the present invention. FIG. 2 is an enlarged cross-sectional view thereof.

  In the figure, reference numeral 1 denotes a nose pad body, which has a substantially oval shape composed of long sides 2 and 2 that are substantially parallel and short sides 3 and 3 that are curved in an arc shape. A mounting leg 4 having a rectangular quadrangular prism shape is provided so as to project toward the side. A concave groove 5 is formed at the base of the mounting foot 4, and an O-ring 6 made of soft silicone rubber, which is an elastic body, is fitted into the concave groove 5. It is important that the diameter of the O-ring 6 is larger than the depth of the concave groove 5, and the outer portion of the O-ring 6 protrudes from the concave groove 5 as shown in FIG. Further, between the both side surfaces of the mounting foot 4, a long hole-like through hole 7 which is long in the front-rear direction is formed, and bolts 9 whose both ends are pivotally supported on the side surface 10 of the pad box 8 are inserted into the through hole. 7, the attachment foot 4 is attached to the pad box 8 in a state of being movable in the front-rear direction. In the figure, reference numeral 11 denotes a pad arm extending from the eyeglass frame, and the pad box 8 is attached to the tip of the pad arm 11.

  The nose pad according to the present invention has the configuration as described above, and an O-ring 6 made of soft silicone rubber, which is an elastic body, is fitted at the base of the mounting foot 4, and a long hole-like through hole 7 is formed. Since the pad box 8 is attached so as to be movable in the front-rear direction via the pad, when a rearward force is applied from the surface side of the nose pad main body 1, the O-ring 6 becomes the edge of the opening of the pad box 8. 12 and the back surface 13 of the nose pad body 1, and the elasticity of the O-ring 6 gives the nose pad body 1 a cushioning property. Therefore, when wearing the eyeglass frame with this nose pad attached, the nose pad comes in contact with the wearer's nose with cushioning properties, realizing excellent fit and comfort, and the eyeglass frame is normal It has the effect that it can be effectively held in position. In addition, the number of parts is small, the manufacture is easy, the appearance is not strange, and the durability is high.

  Of course, it can be used not only for glasses for correcting vision but also for sunglasses.
