Specific embodiment

Now in conjunction with attached drawing, the utility model is further described.

Referring first to Fig. 1, a pair of temple bar cam 100 in use is illustrated.The wearer of one glasses (makes User) 102 just adorning oneself with glasses 110.Although showing that glasses 110 are the running in order to show temple bar cam 100, glasses 110 be representative, and the glasses that temple bar cam can be similar with other structures are used together, such as 3D Mirror, goggles, color correction mirror, plain glass spectacles and other similar instruments.Glasses 110 include nose frame 112, nose frame 112 1 As support by the nose of user 102, be pressed in the most of weight of glasses 110 on the nose 104 of user 102.But it is left The temple bar 114 on side and the temple bar 116 on the right all respectively have a temple bar cam 110.Each temple bar is convex Wheel 100 is support by the face of user 102, holds up glasses 110, not have weight to increase on nose 104.Due to a pair There are two temple bar, two sun for glasses

Cave bar cam 100 uses simultaneously, and a temple bar is normal with a cam.

In preferred case, temple bar cam 100 is made of silicon rubber, has very high elasticity, so as to temple bar Cam 100 in use can be as described below generation deformation, and be restored to original shape after use.In case first In, the silicon rubber used is medical grade silicone, can not will cause user 102 in use in this way and contact temple bar cam There is uncomfortable or adverse reaction in 100 skin.

Referring now to Figure 2, describing to have used is a temple bar 100.Temple bar cam 100 has been attached to glasses In the temple bar 114 on 110 left sides (as shown in Figure 1).In broad terms, temple bar cam 100, which is one, has temple The deformable body of bar receiver 124, size can receive the temple bar 114 of a pair of glasses 110.When the temple on the left side Bar 114 passes through temple bar receiver 124, and main body generates deformation to form the cam valve 142 for adjoining temple bar receiver 124 With 144 (as described in Figure 4).116 temple bar cam 100 rises along the right side of 102 face of user in the temple bar of right side To similar effect, so without individually describing.Once deform in this way, relative to temple bar receiver 124, main body other The shape of cam valve 120 will be presented in part.

When glasses 110 are placed on user on the face, because glasses 110 are ear and the relative usage person for being connected to user Nose it is lower so that the temple bar cam 100 of slightly above nose 104 is toward 118 rotational deformation of direction.Glasses 110 are to user The rotation of nose cause the cam valve 120 of temple bar cam 100 to contact the face on user one side, and toward direction of rotation 118 compressions make glasses 110 be safe on the temple of user until temple bar cam 100.Temple bar cam Conical bore 122 in 100 can make temple bar cam 100 be fully deformed, and such temple bar cam 100 can be cosily Lean against the centre of left side temple bar 114 and the face of user 102.

Referring to Fig. 3, the face of the temple bar 114 in left side and user 102 are constantly on temple bar cam 100 Pressure is generated, temple bar cam 100 is fixed, then keeps glasses 110 on the nose 104 of user 102, such as arrow Shown in 130.Make to generate a small gap 132 between nose frame 112 and the nose 104 of user 102 in this way.Therefore, nose frame 112 Will not nose 104 to user 102 generate pressure, irritation, rubescent or recess will not be generated on nose.

Referring to fig. 4, when putting on 110 pair of glasses, between left side temple bar 114 and the face of user 102, cam The place that valve 120 is drawn, temple bar cam 100 carry out the movement of the direction as shown in arrow 140.Therefore, glasses 110 are fixed on They originally should be on position.It can also be seen that cam valve 142 and 144, they are by the dry cam of temple in Fig. 4 100 part protrusion composition.When temple bar passes through temple bar receiver 124, cam valve 142 and 144 is produced.

Now as shown in Figure 5A, when a temple bar is connect as shown in left side temple bar 114 by temple bar Device 124 is received, temple bar cam 100 assumes that the circular appearance of a transverse shape has in the place that temple bar 114 passes through One tail.Tail corresponds to cam valve 142 and 144 shown in Fig. 4.Remaining rounded portions of temple bar cam 100 are decomposed Released cam valve 120 act on stopped secondary 110 glasses move downward (as shown in Figure 1).

As shown in Figure 5 B, once glasses 110 (such as Fig. 1) are placed on user 102 on the face and glasses 110 start to drop Cam valve 120 as low as their resting position, the temple 102 and temple bar that contact user makes cam lobe 120 to face Direction, rotate inward deformation.The elasticity of temple bar cam 100 facilitates interior rotary motion, this makes it with temple Bar 114 continues to move downward, and shape can produce deformation.As shown in Figure 5 C, due to the deformation of temple bar cam face, cause Temple bar 114 is eventually positioned at the side of cam valve 120, opposite with the face of user 102.The shape of cam valve 120 is From original circular shape deformation, it is by the elasticity of temple bar cam 100 and the presence of conical bore 122 come real Existing, discomfort is brought to avoid to user 102.At this point, the rotary motion of cam valve 120 and deformation stopping and temple Bar 114 does not continue to move downward, but it is fixed in situ by temple bar cam 100.

Now as shown in fig. 6, being less than pedestal lower part or " bottom on pedestal top or " top " 150 (as shown in Figure 8) diameter Portion " 152 (as shown in Figure 7), the preferred case of temple bar cam 100 have a funnel shape and a circular cross-section A rather than temple bar.This conical funnel shape ensures the whole length along temple bar cam 100, the sun Contact between cave bar cam 100 and the temple of user 102.Conical bore 122 and temple bar receiver 124 are from top 150 extend to bottom 152, and in some cases, form the one of the injection molding process of the manufacture of temple bar cam 100 Part, and in other cases, after the initial production of funnel shape, they are cut into temple bar cam 100.Cone Except shape hole 122 and temple bar receiver 124, in preferred case, aperture 154 extends to temple bar from side surface 156 Receiver 124.In a preferred case, there is a rectangular shape in aperture 154, but without departing substantially from the utility model the case where Under, other shapes can be used.The presence in aperture 154 forms two bands (as shown in figure 11) of 154A and 154B, the two Band has elasticity and can be placed in temple bar.It is convex that the aperture makes temple bar more easily enter temple In the temple bar receiver 124 of wheel 100.
