Abstract

PURPOSE:To reduce the thickness of spectacles when they are folded, by supporting pads, which are formed on insides of a pair of lens frames, with elastic bodies and making it possible that these pads are projected outward from planes of lens frames by elasticity. CONSTITUTION:Pads 9 and 9 provided on faces facing each other of a pair of lens frames 1 and 1 are supported with supporting pieces 90 and 90 consisting of elastic bodies. When spectacles are folded, pads 9 and 9 are moved from positions indicated by dotted lines in the figure to positions indicated by solid lines on planes of lens frames 1 by elasticity, and the thickness is reduced. When temples are opened, pads 9 and 9 are returned to positions indicated by dotted lines by elasticity of supporting pieces 90 and 90, and a user can put on glasses. Thus, thin glasses convenient for portability are produced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to eyeglasses having a pair of left and right lens frames protruding from nose pads.

[Conventional technology]

The applicant previously proposed a pair of eyeglasses that can be folded into a plane with approximately the same thickness as the lens frame (Jitsukai Sho E).
;7-178220).

The above-mentioned folding glasses have a pair of lens frames (
1) Rectangular cylindrical receiving pieces (2) (2+) are provided on the upper edge of tl), and both ends of the bridge piece (8) are slidably fitted across both receiving pieces f2) (2). One end of the bridge piece (8) passes through one receiving piece (2), and a screw (5) for preventing removal is screwed onto the tip, and the other end is fitted into the other receiving piece (2). It is clamped using the fixing screw C.

The vine (3) has an auxiliary vine (3υ) and a vine main body (support) pivoted to the outer edge of the upper side of the lens frame (1) as shown in Figure 4, and the auxiliary vine (3υ is attached to the lens frame (11tl)). It is rotatable in a plane perpendicular to the plane, and the vine main body is rotatable in a plane perpendicular to the rotation plane of the auxiliary vine (311).

Further, a torsion spring (43) is interposed at the pivot portion of the auxiliary vine (31) relative to the lens frame (1), and biases the auxiliary vine in the expanding direction.

The above-mentioned folding tomb mirror not only allows the distance between both lens frames to be expanded or contracted to correspond to the interpupillary distance of the wearer, but also has a pair of auxiliary vines o1) + 31) and a vine body as shown in Figure 2. (Support) It is possible to fold both lens frames into a plane with approximately the same thickness as the '11 fi+, and it can be stored in an extremely thin eyeglass case.

[Problem that the invention seeks to solve]

The above glasses are excellent in that they can be made thin, but the nose piece (■) is fixed to the lens frame by a rigid support piece.
In order to make the folded state as thin as possible, the nose piece (9) had to be fixed at a position as close as possible to the lens frame (1). As a result, as shown by the two-dot chain line in FIG. 8, the lenses (11) come too close to the eyes when wearing glasses, which is particularly unsuitable for near-sightedness.

[Means for solving problems]

In order to solve the above problems, the present invention provides a pair of lens frames fl.
) Inside each of the +11, an elastic support piece (nose pad (9)) which is configured to be freely bendable in a direction perpendicular to the lens 01) is placed via a thread, and the nose pad is held by the elasticity of the elastic support piece. It is made to protrude outward from the plane of the lens frame.

[Action of the invention]

The elastic support piece (90) is hardly deformed by a slight load when wearing glasses, and the nose pad pieces (91+91) hold the lens frame (1) ridges at a predetermined position in front of both eyes and hold the lens. Maintain an appropriate distance between the eyes and the eyes.

Even if an impact or a large load is applied to the nose piece (9) in a direction perpendicular to the lens (111), the elastic support piece (90) elastically deforms and absorbs the force. Frame (1
) is small, and there is no risk of damage to the joint.

When the load on the nose piece (9) is released, the elastic support piece (■) elastically returns to return the nose piece (9) to its original position.

〔Effect of the invention〕

The eyeglasses according to the present invention have nose pads (
Even when the lens frame (9) is supported at a position protruding from the lens frame (1> by an appropriate distance), the nose pad (9) can be pressed in a direction perpendicular to the lens to bring it closer to the lens frame U+ #-. Therefore, it can be stored in an extremely thin case.

〔Example〕

A pair of nose pads (91 (91 is a lens frame Fi +
+1) held at an appropriate distance from the mosquito.

The elastic support piece (■) is a torsion coil spring with legs (□□□) extending in the same direction from both ends of the coil portion (91), as shown in FIGS. 5A and 5B, with the coil portion (111) facing upward. One leg M is soldered to the lens frame (1), and the other leg locks the nose piece (9), so that the nose piece (9) protrudes from the plane of the lens frame toward the face. .This nose piece is
As shown by the imaginary line in FIG. 5B, it is possible to resist the elasticity of the elastic support piece and retreat into the plane of the lens frame.

An elastic support piece (OA is as shown in FIGS. 6A and 6B,
It is also possible to use a cylindrical coil spring or an elastic resin body in which the coil center coincides with the protruding direction of the nose piece (9) and adjacent coils are in close contact with each other.

It is also possible to fix it upside down.

When a pressing force in a direction perpendicular to the plane of the paper is applied to the nose pad piece (9) shown in FIG. 5A or FIG. 7A, the elastic support piece ( ) bends in the closing direction, and the nose pad piece (9) shown in FIG. 5B respectively And as shown by the two-dot chain line in FIG. 7B, it is displaced toward the space between both lens frames (1) (1).

Further, by applying a pressing force to the nose pad piece (9) shown in FIG. 6A, the elastic support piece (9A is shown in FIG. 6B)
By bending, the nose piece (9) is displaced toward the space between both lens frames (1) (11).

When the above-mentioned folding glasses are worn as shown in FIG. 8, the elastic support pieces (A) hardly deform, so the distance T between the lenses (111 and the eyes) can be maintained at an appropriate value.

A thin eyeglass case (7) showing the above folding glasses as shown in Figure 3.
When storing the lenses in the
1 (1) is brought close to the pair of receiving pieces (21) until they touch each other to reduce the total width of the lens frame. At this time, the pair of nose pad pieces (91 (9) first butt against each other, but the elastic support Piece (9III) (Since the sieve can be elastically deformed also in the direction along the lens surface, even after the pair of nose pad pieces (91+91 have come into contact with each other, both lens frames 11) tl) can approach each other.

Next, the vine main body is folded and placed in an open eyeglass case (7) as shown by the two-dot chain line in FIG. When pressing the lid ■ to close it, the vine (3) is attached to the lens frame t1) (1) by the lid surface.
is confined within the same plane as Further, the nose pad piece (9) is also simultaneously pushed toward the space between both lens frames tl) (1) by the lid surface. As a result, the glasses are folded into a super flat shape within the case (7). Since the case (7) is thin, it is convenient to carry.

Furthermore, when the lid is opened, the vines (3) will rise in a crossed state due to the action of the torsion springs, and the elastic support pieces (9) will elastically return to their original positions. It's easy to take out your glasses because they go back.

It goes without saying that the glasses according to the present invention can be applied not only to the above-mentioned folding glasses but also to general glasses, and even if an impact or an unreasonable force is applied to the nose pad piece (9), the elastic support piece There is no risk of the joint being damaged due to the elastic deformation of (90), and when worn, the pair of nose pads (9) (9) exerts a restoring force in the direction along the lens surface of the elastic support piece (!l[1). According to
It has excellent effects such as holding the nose with appropriate surface pressure.
