Abstract

The present invention relates to a combination of a spectacles frame 10 and a supporting frame 40. The spectacles frame is provided with magnets 32,34, which are jioned with the corresponding supporting frame magnets 50,52 to fix the two frames together. The jioning surface of the magnet 32,34 are facing to each other, making the movement of the supporting framework is hold back by the internal function of the magnets through the structure of the supporting framework and the spectacles frame.

Description

Glasses

The present invention relates to a kind of glasses, specifically glasses that are provided with an auxiliary frame.

Known techniques once proposed a kind of glasses, and it has the correcting vision eyeglass (prism) that is installed in the frame, and had an auxiliary frame that also is equiped with eyeglass, so that additional function, for example function of sunglasses to be provided.This auxiliary frame is connected on this frame, makes this auxiliary lens be positioned in the place ahead of this correcting vision eyeglass.The problem of this auxiliary frame is that they often hinder eyesight and are connected on this frame in a unsafe mode.

At United States Patent (USP) 5,568, once provided an auxiliary frame in 207, it is connected on this frame by magnetic component.Yet the shortcoming of this auxiliary frame is that it still is easy to be moved because of a unexpected shake.

And one object of the present invention is that a kind of improved glasses configuration is provided, and it can slow down this problem.

According to a first aspect of the invention, the combination of one frame and an auxiliary frame is provided, each framework has first and second magnetic component, they can connect and, use this frame and this auxiliary frame are linked together, this configuration is to make the magnetic component of this auxiliary frame be maintained between the magnetic component of this frame, or is provided with in contrast.

According to a second aspect of the invention, the combination of one frame and an auxiliary frame is provided, each framework has first and second magnetic component, they can connect and, use that this frame and this auxiliary frame are linked together, this configuration makes that this auxiliary frame is to tend to first magnetic component is moved away from each other and force second magnetic component close to each other with respect to this frame mobile on a direction.

The magnetic component of frame preferably is connected in the branch that extend at a side place of an eyeglass fixed part of framework thus.

Best is, this auxiliary frame has and the measure-alike eyeglass fixed part of the eyeglass fixed part of frame, and the magnetic component of auxiliary frame is connected on the member on these branches that extend across frame.

According to the configuration at this specific embodiment that is described, moving of this auxiliary frame stoped by this frame in fact, therefore helps to maintain auxiliary frame with respect to frame.

Will and in detail a specific embodiment of the present invention be described in detail with reference to the accompanying drawings by example now, wherein:

Fig. 1 is the front elevation as a frame of the part of specific embodiments of the invention;

Fig. 2 is the front elevation as an auxiliary frame of the part of specific embodiments of the invention;

Fig. 3 is the view that as shown in Figure 2 auxiliary frame is connected to frame as shown in Figure 1, and it is specific embodiments of the invention;

Fig. 4 is the vertical view along the direction of the arrow A of Fig. 3;

Fig. 5 be between frame and the auxiliary frame the junction, be the zoomed-in view of the B part among Fig. 4, assembly is decomposed in this view;

Fig. 6 is along a view of arrow C direction among Fig. 5; And

Fig. 7 is along a view of arrow D direction among Fig. 5.

See also accompanying drawing, a specific embodiment of the present invention is shown, it has comprised two assemblies basically, and an assembly is called frame, represents with numeral 10 at this, as shown in Figure 1; Also have an assembly to be called auxiliary frame, represent with numeral 40 at this, shown in Figure 2.This frame 10 comprises eyeglass fixed part 12,14, and they are joined together by a bridge 16, is used for fixing correcting vision eyeglass 17,18.At the opposite side of this eyeglass fixed part 12,14, be provided with branch 20,22 (as shown in Figure 4).

Branch

20,22 is connected to a leg of spectacles that extends back 28,30 via hinge 24,26, and leg of spectacles is used for fixing on wearer's ear, mat frame 10 is fixed in its position.

Auxiliary frame 40 has eyeglass fixed

part

42,44, and they are connected by a bridge 46, and to support auxiliary lens 47,48, for example they can be coloured sunglasses eyeglasses.It is identical with the shape of the

corresponding part

12,14,16 of frame 10 that the size of eyeglass fixed

part

42,44 and bridge 46 is designed to, make when auxiliary frame 40 is connected to frame 10, a framework is hidden in after another, reduced the vision uncontinuity between these two frameworks by this, as shown in Figure 3.

Auxiliary frame 40 is connected to mechanism on the frame 10 then shown in Fig. 4 to 7, and this mechanism is by using two groups of magnet that auxiliary frame is fixed in its position basically.

One group of magnet 32,34 is connected to respectively in the

branch

20,22 of this frame, magnet 32,34 (label is that of 34 in Fig. 5) connect and the surface, generally toward each other.Second group additional magnet 50,52 is connected on the auxiliary frame 40 by a line components 54,56.This line components 54,56 is fixed to the front of these

members

42,44, as shown in Figure 2.

In use, this auxiliary frame 40 top of slipping over frame 10 up to the bonding surface of magnet 50,52 slidably with magnet 32,34 connect and the surface connects and.

Magnet 50,52 connect with the surface between distance be selected to basically with magnet 32,34 connect and the surface between distance identical, make when connect and the time, magnet with one slide fixedly connect and, the structure of fixing then by frame 10 and auxiliary frame 40 of this slip is supported.Because magnet 32,34 is configured such that it connects and the surface faces with each other and magnet 50,52 is fixed between the magnet 32,34, one tends to force magnet 50 will be stoped by frame from the strength that magnet 32 separates, and will tend to force

magnet

34,52 to combine.

The present invention will not be subject to specific embodiment described herein.For example, though magnet the 50, the 52nd is set between the magnet 32,34, such layout also can be inverted, and promptly makes magnet 32,34 between magnet 50,52.Further, though magnet connects and be adjacent to branch's 20,22 parts, they also can on the position of approaching bridge 16 places, connect and.
