Abstract
Two segments (1a and 1b) of a circle with an opening supporting a spectacle lens (9) are assembled and fastened by screws (2) screwed in the segments (1 a). The screw (2) has a helical spring (5) accommodated in the cavity (3) of the segment (1b), and the spring is supported on the one hand on the bottom (1d) of the cavity (3) and on the other hand on the head (2b) of the screw (2). The screw is locked to the segment (1a) by means of a circlip (8) constrained in an annular neck (7) machined near the end of the screw (2). The thickness of the snap spring (8) is related to the longitudinal position of the screw (2) relative to the segment (1a) of the ring-shaped lens frame when a predetermined pressure of the spring (5) is reached.
Description
The objective of the invention is to have the assembling of two segment of spectacle-frame circle of opening and fastening device.
Ring shape has the assembling of two segment of spectacle-frame of opening and fastening, no matter is when eyeglass is installed, or afterwards in the use of glasses, all has various problems.
In fact, for the ease of eyeglass is installed, assembling and fastening device preferably are arranged to such an extent that guarantee that ring shape lens frame two segment in the assembling that does not have under the fastening situation, makes eyeglass be put in the circle easily.In a single day eyeglass is accommodated in the circle, and at this moment the manufacturing optician just can hold this circle and eyeglass with a hand and fix with the another hand.
A kind of danger is arranged fixedly the time: if excessive pressure acts on the eyeglass, eyeglass can be out of shape, even can split.Therefore, be desirable according to avoiding eyeglass the mode under the excessive pressure of being placed in that stationary installation is met the requirements.
In addition, for example, when temperature variation is big, particularly when the circle of support lenses is the situation of metal, also can produce a kind of like this stress, it causes the expansion that is harmful to and the effect of contraction.
The object of the present invention is to provide a kind of assembling of the ring shape spectacle-frame sections that meets all these requirements and fastening device.
Reach this purpose by determined equipment in claim 1.
As an example, a kind of embodiment and a kind of modification of figure expression object of the present invention.
Fig. 1 is the front elevation of the part of glasses.
Fig. 2 is the axial section of first kind of embodiment of the assembling at the ring shape spectacle-frame two ends represented in Fig. 1 and fastener.
Fig. 3 is the axial section of a kind of modification of this assembling device similar to the sectional view of Fig. 2.
Fig. 4 is an enlarged detail view of this modification.
Generally comprise two ring shape lens frame that opening is arranged by the face of the glasses of the expression of 1 mark on Fig. 1, its two segment is appointed as 1a and 1b respectively.These two ring shape lens frame are coupled by a nose bridge 1c.
The lens frame two ends 1a of each ring shape and the assembling of 1b and fasteningly guaranteed by screw 2 have only being made 2a by mark, be tightened in the processed screw thread of part in the sections 1a end of circle of front of this screw.
The sections 1b of circle has the cave 3 of a circle, and its end with the 1d mark is got out a hole 4, and this hole is passed by the bar of screw 2.The volute spring 5 that is accommodated in the cave 3 that is partly with that does not have screw thread of this screw, this spring supports on the one hand on the end in this cave 1d, and lean against on the other hand by mark do 2b screw the head on.At last, the part of the processed screw thread of screw 2 is stretched out from sections 1a end, and screw is tightened therein, and its part of stretching out has a recessed neck 7 of annular at the place of flushing of the exterior face 6 of sections 1a, put a pincerlike pad 8 that is called jump ring therein into.The width of this recessed neck 7 or highly make the part of recessed neck be in the inside of the sections 1a of lens frame circle.
Because such arrangement wants to install the manufacturing optician as the eyeglass of eyeglass 9, from being put into ring shape lens frame sections 1b, the screw 2 that is equipped with spring 5 begins, set about carrying out tightening of screw then.Ring shape lens frame two segment have slightly each other apart from the time, spring 5 also is not compressed, and can put into circle to eyeglass 9 at an easy rate like this.
Hand of manufacturing optician is held this circle, applies slight pressure on two segment 1a and 1b, and uses the another hand, tightens screw 2 by means of a screwdriver.When the suitable pressure of representing spring 5 to him at the resistance of tightening has reached, his interrupt operation.
The manufacturing optician selects its thickness and screw in a cover jump ring 8 of different-thickness that he has annular recessed neck 7 is from consistent that of the width of surperficial 6 exposed portions serve of ring shape lens frame.He is placed on the jump ring 8 of firm selection in the recessed neck 7, and this jump ring is guaranteed the fixing of screw when stoping screw released out of turn like this.
Some jump rings 8 that can have different-thickness are necessary, because screw 2 lengthwise position final with respect to the ring shape lens frame changes with various factors, as the permissible error of the manufacturing of spectacle-frame and eyeglass, the manufacturing optician wants the pressure that acts on eyeglass seen, or the like.
By means of this device, the installation of eyeglass is very easy, and can carry out under the situation of the harm that does not damage eyeglass.In addition, the pressure variation that produces owing to temperature contrast does not all have injurious effects to eyeglass, because the variation of these pressure has all been absorbed by spring 5.
Experiment shows that spring 5 plays a part a vibroshock, can protect eyeglass when glasses fall accidentally.
Replace owing to recover the arc packing ring 10 that spring 5 is placed in the cave 3 of ring shape lens frame 1b end, the modification of Fig. 3 and Fig. 4 is different from first kind of embodiment.Be constrained on this packing ring on the bar of screw 2 is placed at the end in a 2b of screw and this cave 3.Volute spring with respect to first kind of embodiment, the benefit of this packing ring is not only axially to make screw 2 stands under load, stop screw self to rotate by on attached to the screw thread of the screw among the sections 1a of ring shape lens frame, producing friction, and because the following fact.Producing a kind of direct contact between screw and the sections 1b by friction: when packing ring was compressed a little by the head of screw, it just vised the bar of screw by its center pit, and was pressed on the sidewall in cave 3 by its periphery.Therefore cause stoping the double effects of the released out of turn friction of screw.
