Technical field

The utility model relates to a kind of mirror leg configuration and corresponding frame, and especially, the utility model relates to a kind of frame with hinge temple of bistable characteristic.

Background technology

As is known, typical frame comprises preceding frame that eyeglass is installed and a pair of for the mirror leg on the ear that preceding frame is supported on the user thereon.

Typically, the mirror leg must provide the chance of side direction rotation, in order to be suitable for the width of user's face at least, but preferably is closed in order to can be folded on the preceding frame in order to reduce the overall volume of glasses.

Therefore, before the mirror leg of integral type type may be securely fixed on the frame time, must utilize the elasticity of the material of formation mirror leg or structure to guarantee specific lateral flexibility.The example of this structural model is shown in US5367344, US7264348 and the DM/053079.Although these schemes are light and have aesthetic originality, they have various shortcomings, and for example expensive and refrative mirror leg is in order to put glasses in the spectacle case complicacy.

On the contrary, most glasses provide hinged hinge between each mirror leg and preceding frame.Two joint elements that are hinged by pin or screw are provided traditionally, and the former is installed on the mirror leg, the latter is installed on the village head of frame before the glasses.There are a large amount of variations of this scheme.

Now, above-mentioned glasses need to increase the side direction rotation of the mirror leg with the gratifying elasticity folding between open position and make-position urgently; And preferably, mirror leg rubber-like is excessively opened motion, that is, except stably limit by hinge arrangement open the chance of opening, it may overcome elastic reactance and take place; At last, in use may become flexible although it should be understood that hinge attachment screw or pin, this result (being reacted in the use demand of glasses) is permanent to be kept.

Embodiment

Figure 1A-1D illustrates according to frame part of the present utility model.Although the part of the village head (endpiece) 1 of frame before frame before the not shown glasses, accompanying drawing show, the village 1 end at the hinge axis 3(that is connected with mirror leg 2 right hand side mirror leg in reference to the accompanying drawings, left hand side mirror leg is identical).Limit constraint between the village 1 and the mirror leg 2 by fixing hinge axis 3 traditionally, hinge axis 3 for example is the form of the screw 3a in the through hole among the terminal forked portion 2a that inserts with the mirror leg 2 of terminal nose the 1a connection in the village 1.

Two different parts that two different functions are divided into framework according to Frame Design of the present utility model.In other words, according to the utility model, folding (snap) spinfunction with stable open and close position is entrusted to the head part of the mirror leg adjacent with hinge axis 3, and excessively opening function is entrusted to the main part of mirror leg.

Therefore, according to first modification of the present utility model, near the head of mirror leg hinge axis 3 partly is rigid solid, in order to can hold the seat (referring to Fig. 1 C) of elastic mechanism, perhaps can be supported near the acting force that (especially excessively the opening under the condition) of hinge axis presents at least.On the contrary, the main part of mirror leg body is enough carefully to have the cross section that reduces and made by enough flexible structure and material: this part is guaranteed the elasticity of mirror leg during excessively opening.Suppose that the relative size in xsect is suitably limited, the suitable material that is used for this purpose is bronze, stainless steel and synthetic material, as carbon fibre fabric.

Preferably, the village head part 1 that mirror leg 2 is hinged to also is rigidity, hard, firm, is for example made by nickeline, in order to guarantee good behavior and the durability of elastic mechanism.

In more detail, with reference to figure 3A and 3C, the proximal part of mirror leg head is increased and has a container cavity 21 for flexible member 22.Local longitudinal axis along the mirror leg obtains container cavity 21, makes them between two forked portion of hinge fork 2a.Two forked portion of hinge fork 2a end at the circular section concentric with pan 31 separately, and pan 31 is used for engaging with screw 3a, and preferably, one in two holes is internal thread hole.The circular section of two hinge forked portion extends across about 180 ° circular arc, and with respect to seat 21 the axis a-a ' symmetry at the center of passing hole 31.

The lateral surface of mirror leg 2 is namely at the most visible surface, outside of the framework (S among Fig. 1 D ₁) the end do not flush with the circular section of forked portion of fork 2a, and provide recessed step 23, the use of recessed step 23 will be described below.

Village head part 1 has end portion, has two relative flat surfaces with nose 1a in two forked portion that are connected fork 2a in described end portion.The outmost surface in two relative flat surfaces 1a ' and the village 1 is in a ratio of depression: in fact, shown in Fig. 2 C, the width d ' of nose 1a is than the width D of village head ' little.This configuration makes in case pitch 2a and is combined with nose 1a by screw 3a, and the basic outside surface with the village 1 in the end of two forked portion of fork 2a flushes.

Have through hole 11 perpendicular to flat surfaces 1a ' at nose 1a, through hole 11 is used for holding screw 3a to limit hinge axis 3.Therefore, when the mirror leg when village head is combined, through hole 11 with the fork 2a forked portion on two holes align.

Nose 1a goes out to limit curved surface from village head process, and the radius R 5 of curved surface is 11 radius and not concentric with it much larger than the hole.Radius R 5 advantageously equates with the milling radius of the instrument that is used for evening up sunk surface 1a ', wherein by remove material acquisition sunk surface 1a ' from hard village head.

Nose 1a needn't form with the first body in the village of preceding frame, and it can be a part that is soldered on the head of the framework village or is integrated into by embedding (under the situation that preceding frame is made by plastic material) the independent hinge components on the head of the framework village.

Nose 1a further has the suitably edge contour of cam face, the edge contour of cam face has first composition plane 12 and second composition plane 13, first composition plane 12 is parallel with the outside surface in the village 1 substantially, second composition surface 13 is arranged to become about 80 °-90 ° (perhaps different angles with respect to first composition plane, depend on the closing angle that imposes on the mirror leg with respect to the preceding frame of glasses), and form fillet 14 mutually.

The end sections in the village 1 does not flush with second composition surface 1, extends tooth 15 but extend a little to be connected and to form with the lateral surface with the village 1, and the height that extends tooth 15 part height and the village 1 is identical, and part highly equates with the height of nose 1a.

Finish linkage by little opposite piston 24.Under installment state, piston 24 is arranged between the

cam surface

12,13,14 of the spring 22 that holds in present 21 and nose 1a (referring to Figure 1B and 2C).

Under installment state, screw 3a will pitch 2a and nose 1a combines.Fork 2a is set to intersect with nose 1a, and two forked portion connect with smooth sunk surface 1a ', guide by described surface and rotate.The end circular contour of two forked portion rotates freely in the curved surface that with the radius is R5 is the sunk area of village head of profile.

According to the utility model, as mentioned above, the middle body C (Fig. 3 D) of the mirror leg in the back to back downstream of present 21 housing region A by attenuate widely and be made into flexible, preferably by for example bronze or stainless metal or for example the synthetic material of carbon fiber make.For example, the middle body C of mirror leg has the length of about 60mm and has the square-section (height is determined by the required aesthetics of specific glasses) that thickness is approximately 0.5mm.At last, end sections F (being used for being supported on user's ear) at the mirror leg, thin rectangular profile can be folded to form firm free terminal, is for example covered by plastic material, and it is long and have an end sections of the circular section of about 1.35-1.5mm diameter for example to form 60mm at least.

Fig. 4 A illustrates the mirror leg 2 (that is, mirror leg 2 in use) that is hinged to the village 1 at open position according to of the present utility model.In this case, the extension tooth 15 in the village 1 engages with the step 23 that arranges by fork 2a, in order to determine lateral surface continuous of the lateral surface of mirror leg and village head, as detecting from the bottom solid line of Fig. 4 A.Piston 24 is biased on second cam surface 13: the position is stable, because owing to angle 14 will produce thrust at spring 22 to the unwilled rotation that the approaching motion of axle a-a ' causes, thereby will produce stable opposite elastic reactance.

If automatically apply revolving force (Fig. 4 B) at the mirror leg, may overcome the elastic reactance of spring 22 (temporarily compression), be supported on (Fig. 4 C) on first cam surface 12 until piston 24.Because that sets forth above is identical, this make-position of mirror leg also is stable.

Except compare with the accidental closure of mirror leg stable, the open position shown in Fig. 4 A has been determined the end of travel of elastic mechanism, because the extension tooth 15 in the village 1 engages with the adjacent end portion step 23 partly of mirror leg 2.Do not utilize elastic mechanism or do not exert pressure to elastic construction according to the generation of excessively opening of the mirror leg 2 in the mechanism of the present utility model, but entrust to the elastic central section of the folding mirror leg that allows suitable X ° (for example nearly 20 °, in Fig. 3 D, be clearly shown that).

In a word, guarantee elasticity folding function during the opened/closed of mirror leg by the elastic mechanism that is arranged on " ball spring " type in the hinge area; Therefore, the head of mirror leg or close end zone A constitute in firm mode, obtain to be used for the housing of spring 22 and piston (or tumbler or spherula) 24, and the cam surface that piston 24 is used on nose is operated; Extend the closed any slit of the connection that takes place between tooth 15 and the step 23 and guarantee the continuity of the aesthstic essence of gratifying continuity, especially outside surface, determine the end of travel of rotation simultaneously and prevent being further rotated of elastic hinge mechanism thus.What the elasticity of the middle section C by utilizing the mirror leg obtained the mirror leg individually excessively opens motion, and wherein the middle section C of mirror leg is suitably made by bronze, stainless steel, carbon fiber or other materials that can guarantee the sufficient elasticity deformation behaviour.Therefore the inherent elasticity by the mirror leg rather than guarantee that by the elastic mechanism that inserts mirror leg inside it excessively opens motion.

Generally speaking, in original mode, the mirror leg is made up of three different zones (specific function of carrying out according to them has different shapes):

Head part A (length is about 10-20mm), harder, than rigid solid, be used for cooperate with elastic mechanism, especially (under situation about having illustrated) be contained in for spring 22 inside;

End sections F preferably has round section, and is made into to be folded (plastic deformation) to generate the end of the mirror leg on the ear that cosily is contained in the user;

Middle body C has the cross section that reduces that is suitable for guaranteeing enough resilient property, to allow the elastic deformation towards the outside of mirror leg.

Allow advantageously to realize the purpose set forth above according to scheme of the present utility model.

Two functions are separated into the scheme that two elastic movements in the zones of different of mirror leg allow to realize stronger, more cheap and easier enforcement.In fact, the use of ball spring device is simpler and more cheap than traditional load bearing component, allows to realize identical functions but connect mutually with the pliability of the difference of mirror leg.And under the situation that elastic mechanism lost efficacy, hinge loses the elasticity folding during the opened/closed, but continues as simple hinge work, and owing to excessively open the on commission zones of different of giving the mirror leg of rotation, it is not compromised.Therefore, even under the situation that elastic mechanism lost efficacy, glasses still keep the most important characteristic of the open and close of mirror leg and advantages of good abrasion and excessively open the cooperation that motion provides by elasticity.

As long as relate to the elastic part of mirror leg, described part mould and shear step during made very simply, therefore also obtain excessively to open in dog-cheap mode.

Than traditional elastic ball spring device, more attractive and less be limited by the restriction (for example, hinge axis needn't align with the longitudinal axis of mirror leg) that prior art is undertaken aesthetically according to scheme of the present utility model.

What however, it should be understood that is that the customized configuration that above-described novel protection is not limited to illustrate changes but extend to any other structure of realizing identical use.

For example, although in description with reference to the mirror leg of integral type, namely, single core body is made of or is comprised to three main parts of mirror leg discrete component, but can suppose that housing with elastic mechanism is not prepared into is integral with the mirror leg, but is attached to the mirror leg by associated methods known to those skilled in the art (gummed, fix, weld by the mode of screw, pin or rivet).

As example, Fig. 5-6B illustrates possible modification.Modification shown in Figure 5 is suitable for providing the leg of the plastic lens with metallic core especially: in this case, the metallic core of mirror leg satisfies the inventive principle that the utility model is set forth.In fact, metallic core shown in Fig. 6 A and the 6B has the head part A, the head part A has bigger thickness, and owing to two essence reasons are rigid solid: on the one hand, for can be soldered (perhaps otherwise in conjunction with) to the hinge components of the seat that comprises flexible member, on the other hand, because during the fitting operation in the plastic sheath that core body is coupled to the mirror leg, it is to firmly grasp and induction element.And it has the middle body (C) of thin flexibility and has the end sections F of the section on the ear that is suitable for cosily being supported on the user.

Be under the situation about being made by plastic material at the mirror leg, metallic core (must satisfy strict aesthetic requirement) can have the middle body C that the mode of the mode (Fig. 7 B) of through hole or other holes (Fig. 7 A) by reducing its section (being moment of inertia) further alleviates, and increases flexible thus.

Similarly, it is contemplated that and overturn shown configuration, the element of the elastic mechanism between exchange village head and the mirror leg.That is to say that elastic mechanism (spring+piston) can be arranged in the end sections of village head rather than on the mirror leg; And, in this case, the mirror leg will be divided into three different perform regions and two motions (opened/closed and excessively open), and independent element is entrusted in two motions, and belong to two opposite hinge components: especially, the opened/closed folding will be moved into the village head of preceding frame.In fact, the ball spring device has the advantage littler than the volume of traditional load carrier, so it also can be installed on the head of the village and does not damage the aesthetic property of glasses.The example of this variation is shown in Fig. 8 A and the 8B, wherein can notice, the village 100 has the elastic hinge structure, and the mirror leg still has for head part, the flexible portion C of first rigid solid that cooperates with village head and is used for cosily being supported on end portion F (Fig. 8 C) on user's the ear.

In the modification shown in Fig. 8 A-8C, can notice that near the soldered tooth nose (nose portion on the leg of spectacles and do not obtain at village head) does not extend beyond cam surface, so that the composition plane between two hinge fractions falls into corresponding hinge axis substantially.

In the modification shown in Fig. 9 A-9B, can notice that the type of configuration remains in the village head of flexible member former frame.In this case, the nose portion of hinge is not integral with mirror leg core body, but obtains as independent part, is attached on the mirror leg by technology more known in the art (for example by welding) then.

Figure 10 A-10B illustrates further modification, has the design similar to Fig. 8 A.In this case, two hinge components 100 ' being made by the strong metal material and 102 are by screw pin 103 combinations.Concave portions 102 is incorporated into the flex temple element of being made by synthetic material such as carbon fiber 104.According to unshowned another kind of modification herein, for example under the wide especially situation of mirror leg, it is contemplated that also each mechanism is configured to one abreast above another for each mirror leg provides two (perhaps more generally, a plurality of) elastic ball spring devices.In this case, the identical method that also will relate to the separation of two elastic movements as previously described is applied to the part of the framework of visibly different glasses.
