Description

Detachable auxiliary lens structure with magnets

  The present invention relates generally to

  neat and auxiliary lenses that can be detachably coupled

  chable to glasses. More particularly, the present invention relates to the means by which the auxiliary lenses are attached to the glasses. More particularly still, the present invention proposes a structure allowing the auxiliary lenses to form a solid connection when it is fixed to the glasses, without risk of separating from the glasses because of a slight change in shape of the frame of the glasses when the glasses are fitted on the head of a

user.

  In the past, several means have been used to fix

  auxiliary lenses on glasses. One of them is a disposi-

  clamping wire, which is permanently attached to the auxiliary glasses

  liaries. The clamping device adjusts to the frame of the glasses to hold the auxiliary lenses on the glasses. However, the

  tightening devices do not give the glasses a nice appearance.

  Another way to attach auxiliary lenses to glasses

  your is to use magnetic material. This is currently a popular way of attaching auxiliary lenses to glasses, and several devices have been proposed and patented, among which are

  found in the document "Detachable Sunglasses With Magnets" (lu-

  detachable sunglasses with magnets) filed on behalf of Sunreeve Company Limited on May 18, 1995 and published by the R.O.C. Intellectual Property Office

  China) under publication number 274588, a device

felt in figure 6.

  According to the document mentioned above, with reference to FIGS. 6 and 7, magnets 101 are fixed to two end parts of the frame 10 of the glasses while magnets 201 are fixed to two end parts of the frame. frame 20 of the sunglasses

  liars without branches; so the auxiliary sunglasses without bran-

  can be fixed to glasses by means of magnets 201, 101

  attracting each other to form a bond.

  However, with experience, we have noticed that the branches

  These glasses widen when adjusted over a user's head, which rotates the end portions of the frame by an angle. The rotation of the end parts of the frame changes the position of the magnets which are mounted thereon, which causes the close contact of the magnets of the sunglasses without temples and the magnets of the glasses, and consequently the glasses, to be lost.

  sun glasses fall under extreme conditions.

  As with the deck-mounted sunglasses, the link turns out to be too weak and the sunglasses can easily

  take a certain angle to the desired position.

  To overcome the disadvantages of the means mentioned above

  above, other means have been proposed, including glasses

  auxiliary for glasses described in the document filed on the 1st

  vember 1995 under the Republic of China publication number 308308 and a means for attaching auxiliary lenses to

  glasses described in the document filed on July 21, 1997 under the number

  Republic of China Publication No. 326924.

  According to the document published in the Republic of China under the number

  mero 308308, with reference to FIG. 8, magnets 303 are mounted on the end pieces 302 of the frame 30 of the glasses, the end pieces 302 being provided to connect to the arms 301. Second magnets 402 are mounted on end portions forming a support 401 for sunglasses without temples 40 so that the sunglasses without temples 40 can be fixed to the glasses by means of the

  bond between the magnets 303 and 402, the end parts forming sup-

  port 401 resting on the ends 302 of the frame 30 to provide

  stable support for sunglasses without temples 40, as my-

very in figure 9.

  Furthermore, according to the document from the Republic of China pu-

  coded under No. 326924, with reference to FIG. 10, magnets 501 are mounted on end pieces 502 of spectacles 50 in such a way that recesses 503 are formed on the end pieces 502. Spectacles without arms 60 are provided, which have protrusions 602 at two ends and magnets 601 mounted on the protrusions 602 in such a way that the magnets 601 each form a protrusion; thus, the sunglasses without temples 60 can be coupled to the glasses by means of the link between the magnets 501 and 601 attracting each other, the recesses 503 retaining the

  magnets 601 to strengthen the bond, as shown in Figure 11.

  The three means mentioned above provide a more stable and safer connection between the glasses and the sunglasses without temples, however the user must put the sunglasses without branches by the top of the glasses which are adjusted on his head to because of the presence of the projecting parts 401 of FIG. 10 and the end parts forming a support 401 of FIGS. 8 and 9. This is different from the way in which the user is used to laying

  sunglasses without temples, i.e. by the front of the glasses

  sharp. Fastening means of this type are therefore not very practical.

  ques. Detachable auxiliary sunglasses with magnets

  the present invention are designed to be adjustable

  detachable on primary glasses. Auxiliary sunglasses

  binders are branchless and magnets are mounted on elements

  rotating sunglasses on two end parts of the

  ture, the rotating elements being able to pivot on the end parts.

  The auxiliary sunglasses provide protection to the user against elements of sunlight which can damage the view when they are fitted on primary glasses worn by the user; primary glasses have magnets in them

  positions corresponding to the positions of the magnets of the sunglasses

  auxiliary leil so that the sunglasses can be

  fixed on the primary glasses thanks to the link between the magnets

rant each other.

  The magnets of the auxiliary sunglasses, being able to pivot on the end parts at the same time as the rotating elements, can maintain a stable and close contact with the ai-

  primary glasses even if the position of the magnets

  primary net changes by a certain angle because of a change in

  forms primary glasses during use.

  The present invention provides a pair of glasses comprising

  both detachable auxiliary glasses. This pair of glasses

  take a first pair of glasses including a first frame

  with two opposite ends, a pair of first immobile glasses

  stalled in the first mount and supported by it, a pair of connecting parts, each fixedly fixed at a respective end of the two opposite ends of the first mount, a pair of first magnets, each of them being housed inside

  a respective connecting part, and a pair of branches, each

  not being hinged to a respective connection part.

  This pair of glasses also includes a pair of glasses.

  auxiliary net that can be detachably attached to the first

  re pair of glasses, the pair of auxiliary glasses including a second-

  frame having two opposite ends, a pair of

  lens caps installed in the second frame and supported by it

  ci, a pair of end caps respectively fixed at the two op-

  of the second mount, a pair of rotating elements, each of them being pivotally coupled to a respective end piece, and a pair of second magnets, each of them being housed inside

  a respective rotating element, each of second magnets being dis-

  placed in aligned relationship with a first respective magnet of said pre-

  first magnets of the first pair of glasses and so as to create an attraction between them in order to detachably attach the pair of

  auxiliary glasses to the first pair of glasses, the pivotal coupling

  so many rotating elements now substantially aligning

  between the first and second magnets during the distortion of the first

  better frame when the first pair of glasses is worn by a user. The present invention will be better understood on reading the

  following detailed description, with reference to the accompanying drawings

  Detachable auxiliary glasses with magnets of the present

  The invention, with reference to FIG. 1, comprises a frame 2, sunglasses 21 mounted in the frame 2, end caps 221 in two end portions of the frame 2, which end caps 221 are formed so that they can each be pivotally connected with a respective rotating member 222 to form a hinge (designated by

  as a whole by reference 22). A magnet 23 is mounted inside

  laughter of a respective rotating element 222.

  A pair of glasses is provided, comprising a frame 1, lenses 11 mounted in frame 1, connection parts 12 in two end parts of frame 1, magnets 13 each mounted on a respective connection part 12 , and branches 14 pivotally connected to the connection parts 12; the magnets 23

  sunglasses without temples are placed in correct positions

  corresponding to the positions of the magnets 13 of the glasses. So the

  auxiliary sunglasses without temples can be attached to the lights

  sharp thanks to the link between magnets 13 and 23 attracting each other

  very. In addition, the hinges 22 in two end parts of the sunglasses allow the rotating elements 222, inside which the magnets 23 are mounted, to rotate as a function of the position of the magnets 13 connected to the magnets 23. Thus, when a user puts on the glasses with the auxiliary sunglasses fitted thereon, the

  auxiliary sunglasses can be securely attached to glasses

  even if the magnets 13 rotate at an angle due to

  the enlargement of the distance between the branches 14 when the glasses

  tes are adjusted on the head of a user.

  From the above description, it can be understood that the

  23 magnets pivotally connected to auxiliary sunglasses

  can still be in close contact with the magnets 13 of the glasses

  regardless of the change in position of the magnets 13 during use. In addition, the auxiliary sunglasses can be placed on the glasses from the front of the sunglasses worn on the head of the user, which preserves a very practical way of

wear the glasses.

  It is understood that the description of embodiments

  The foregoing has been given for illustrative purposes only and is not limited to

  tif and that variants or modifications may be made to it

  in the context of the present invention.
