Abstract

A nose pad that can swing in all directions and elastically displaces in the front and back directions is also provided. A leg portion 3 made of a soft synthetic resin and having a substantially inverted J shape is integrally formed from the vicinity of opposite ends of a back surface 2 of a nose pad body 1 made of a soft synthetic resin having a plate shape. The free ends of the leg portions opposed to each other are integrally connected by a horizontal arm member 8, and a box connecting block 11 for connecting the box 10 is integrally formed on the central upper surface of the horizontal arm member. .

Description

  The present invention relates to a north pad, which is one of the components of a spectacle frame, and more particularly to a nose pad with excellent fit.

  The nose pad is a component of the eyeglass frame that secures the eyeglass frame to the face of the eyeglass wearer. If the nose pad is inappropriate, the eyeglass frame may be displaced, resulting in a noticeable wearing feeling. It will also harm the vision correction.

  In order for the nose pad to perform its function, the nose pad itself has appropriate flexibility and elasticity and can swing freely in all directions with respect to the nose pad mounting foot implanted from the spectacle frame body. Although it is necessary to fit the nasal bridge of glasses wearers who are not the same, it is difficult to find a low-cost nose pad that can meet this demand.

  Therefore, the present inventor proposed a low-cost mass production nose pad that can swing freely in all directions with respect to the nose pad mounting foot as disclosed in Japanese Patent Laid-Open No. 10-170871, succeeded in commercialization, and has been well received. However, this nose pad still has a problem in the degree of freedom of displacement.

That is, the nose pad proposed in Japanese Patent Laid-Open No. 10-170871 can swing in all directions with respect to the nose pad mounting foot, but the elastic displacement in the front and back direction cannot be performed as smoothly as the swing. .
In other words, in this nose pad, a pair of projecting members are integrally connected by arm-shaped beam members. Therefore, when pressure is applied to the nose pad in the front and back direction, the arch-shaped beam members are structurally mechanical. Since the upper arch is constructed and the beam member is stretched to hold its position against the compressive force applied to it, the elastic displacement of the nose pad in the front and back direction could not be performed as smoothly as the swinging is there.

  The inventor not only can smoothly swing in all directions, but also can smoothly perform elastic displacement in the front and back direction, and as a result of conducting research to realize a nose pad with further improved fit, We succeeded in developing a new nose pad that can realize these in spite of low cost, and propose it as this invention here.

  From the vicinity of the opposite ends of the back of the nose pad body made of soft synthetic resin in the shape of a plate, legs that are made of soft synthetic resin and have a substantially inverted J shape are planted integrally, The free ends of the opposed leg portions are integrally connected by a horizontal arm material, and the above problem is achieved by a nose pad in which a box connecting block is integrally formed on the central upper surface of the horizontal arm material. Settled.

  As shown in FIG. 2, the box connecting block of the horizontal arm portion is inserted and connected to the box of the nose pad mounting foot for use, and the legs implanted from the back surface of the nose pad main body are substantially inverted J Because it is shaped like a letter, the nose pad body not only swings freely in all directions up, down, left and right, but one end of the leg is a free end, and the leg has an arch structure in structural mechanics. Because it is not elastically displaced in the front and back direction indicated by the arrow ×, the nose pad body fits moderately to the nose bridge of the spectacle wearer who is not the same as a different person, causing the glasses frame to slip off Without having an excellent effect of correctly holding the glasses frame. It also has a sophisticated appearance, is easy to manufacture, is highly durable, and has extremely high practicality.

The perspective view of one Example of the nose pad which concerns on this device. Similarly, the perspective view of the state attached to the box of the nose pad attachment leg of a spectacles frame. Similarly, the perspective view of another Example.

  From the vicinity of the opposite ends of the back of the nose pad body made of a soft synthetic resin having a plate shape, legs that are made of a soft synthetic resin and have a substantially inverted J shape are integrally planted and opposed to each other. The greatest feature is that the free ends of the legs are integrally connected with a horizontal arm member, and a box connecting block is integrally formed on the central upper surface of the horizontal arm member.

FIG. 1 is a perspective view of an embodiment of a nose pad according to the present invention. In FIG. 1, reference numeral 1 denotes a nose pad body made of a soft synthetic resin, which has a plate shape.
Then, legs 3 and 3 made of a soft synthetic resin and having a substantially inverted J shape are integrally planted from the vicinity of both ends opposed to the back surface 2 of the nose pad body 1 toward the inside.

  As shown in the figure, the leg portion 3 having a substantially inverted J shape has a base 4 and a folded portion 6 extending from the top portion 5 in a distributed manner, but the folded portion 6 is shorter than the base portion 4 and is substantially half the length thereof. That's it. And the free ends 7 and 7 of the folding | returning part 6 are connected by the horizontal arm material 8, and the nose pad attachment leg extended from the spectacles frame which abbreviate | omitted illustration on the center upper surface of this horizontal arm material 8. A box coupling block 11 coupled to a box 10 provided at the tip of 9 is integrally attached. In the figure, reference numerals 12 and 13 denote through holes used when the box 10 and the box coupling block 11 are coupled.

  There are various types of couplings between the box 10 and the tip of the nose pad mounting foot 9, and as shown in FIG. The slit 14 may be clamped by a clamping piece provided at the tip of the nose pad mounting foot.

  The nose pad body 1, the leg 3, the horizontal arm member 8, and the box coupling block 11 are all integrally formed of a soft synthetic resin, but a soft elastomer such as polyester or polyethylene is used in terms of elasticity and flexibility. Preferably used.

  This embodiment has the configuration as described above. As shown in FIG. 2, the box connecting block 11 of the horizontal arm 8 is inserted and connected to the box 10 of the nose pad mounting foot 9 for use. In addition, since the leg portion 3 implanted from the back surface of the nose pad main body 1 is formed in a substantially inverted J shape, the nose pad main body 1 not only swings freely in all directions, but also the leg portion. Since one end of 3 is a free end and the leg 3 is not an arch structure in terms of structural mechanics, it is also elastically displaced in the front and back direction indicated by the arrow x, and the same as a different person The nose pad main body 1 is appropriately fitted to the nose bridge of the eyeglass wearer who is not, and has an excellent effect of correctly holding the eyeglass frame without causing the eyeglass frame to slide down. It also has a sophisticated appearance, is easy to manufacture, is highly durable, and has extremely high practicality.

  It can be used not only for eyeglass frames for correcting vision but also for all glasses frames that are held on the nose bridge by a nose pad, such as sunglasses and protective eyewear for work.
