Description

Eyeglass hinge mechanism Technical field

The present invention relates to a hinge mechanism for eyeglasses having a novel structure. Background art

The end of the front that connects to the temple is called Ji. Especially metal objects

It is called Loy Lo or Yo Loychi. The temple has an opening and closing function (hinge function) so that it can be opened when used by the ear and closed when closed. In general, there are various types of _D hinges where hinges are used as hinge mechanisms. For example, one side of the putty (the joint between the front and the temple, also known as a horseshoe) is integrated with a sinking hinge or rim lock mounted so that the front and temple mounting surfaces are flush with each other. Hinges, Tomo hinges where the ends of the blocks and the ends of the blocks are directly combined. FIG. 1 is a perspective view of a tomo hinge. Align the screw hole 1 1 1 of the top 1 10 at the top of the temple 1 with the screw hole 21 1 of the top 210 at the front (H 2 in the figure), insert a screw into the screw hole, and fix the temple. Along with the abutment 1 12, 2 12, it is possible to perform a sliding movement (rotation) simultaneously with a sliding movement. Fig. 1 (a) shows a form in which a temple piece is inserted into a temple piece, and (b) shows a form in which a temple piece is inserted into a temple piece. The abutment not only serves as a guide for the sliding movement, but also controls the degree of opening of the temple. The part connected to the rim 3 is a rim lock 220, and the rim is attached to the rim by brazing (for bonding metal), adhesive (for plastic, synthetic resin, or the like), or screwing.

As a pair of eyeglasses that provide a rotation mechanism that can always maintain the resistance to the rotation of the temple against the hitch and can also be adjusted without a hinge, “Temporary rotation mechanism of the temple with respect to the bracket and its glasses” (JP-A-2000-206467) is there. FIG. 2 is a basic view of the turning mechanism (hinge mechanism) shown in the present invention. "T" and "B" added before the symbol in the figure are added to the symbol shown in the original figure, and represent the temple and bracket. Braquet A unit is equivalent to a unit. Although the configuration is close to that of FIG. 1 (a), the expansion member B3 is pressed without using a screw to generate a moderate resistance to rotation. A bearing portion B1 is provided at the end of the bracket B, and a hollow hole (hole) B1H and a cutout portion B11 are formed in the bearing portion. On the other hand, at the tip of the temple T, a shaft 部 having a hollow hole (hole) T2H is provided. Insert the shaft part T2 from the notch part B11 and push it into the guide groove B12, align the hollow holes T2H and B1H, press the expansion member B3 from above the hollow hole B1H, insert it, and connect the bracket and temple. The expansion member generates an appropriate resistance force when the temple is opened and closed, and enables rotational movement without rattling. FIG. 2 (B) shows an example in which a cutting groove T22 is cut in the shaft portion. With this cut groove, even if the notch portion B11 is slightly smaller (even if the notch length is short), the shaft portion T2 can be narrowed. It can be pushed into B1. The reason for reducing the length of the notch is to narrow the rotation range of the temple (normally, the opening of the temple is 90 degrees, but when the angle is 60 degrees, the length of the notch should be shortened. Adjust).

The most common hinge mechanism seen in the prior art is a hinge. In the case of a hinge, a screw connects the temple to the front (usually via a tie). It is preferable that some force is applied to open and close the temple. In the case of hinges using screws, resistance can be created by screw tightening and sliding (friction) at the abutment. However, in the case of screws, there are problems such as loosening of screws and increase in the number of parts. For this reason, various structures that do not use screws have been devised. In the above-mentioned "Turning mechanism of the temple with respect to the bracket and its glasses", the bearing portion of the bracket (H) and the shaft portion of the temple are connected by the extension member, thereby generating resistance and preventing rattling. . However, the screws are replaced with expansion members, and the number of parts is the same as that of the hinge. In addition, the opening and closing angle of the temple is adjusted at the notch, and the bracket is provided with a groove, so the structure is not simple and it is difficult to machine parts.

Eyeglasses made of precious metals (eg 18K gold) are very popular. However, glasses using metal have disadvantages such as an increase in weight. Therefore, the weight of the frame has been reduced by making the frame thinner or rimless. For this reason, hinges that use screws to reduce the number of parts tend to be avoided. Also hinges extra „

Adding extra parts complicates the structure and hinders the thinning of the frame.

In view of the above, the problem to be solved by the present invention is to develop a hinge mechanism having a simple structure in a metal frame eyeglass (a rimless one is also possible) with a thin temple and slimy. . Disclosure of the invention

In order to solve the problem to be solved by the invention, in the present invention, a hinge mechanism is constituted only by a wire-like metal member used for a metal alloy or a temple. As the structural form, a hinge mechanism that combines the frames described in the prior art will be used. The part corresponding to this top is made of a circular ring made of the same material as that of Choroy and Temple, and a hinge mechanism is formed by combining both rings. Specifically, it is as follows.

In the rotating mechanism of metal temples and metal alloys, which are eyeglass parts, a circular pivot shaft serving as a rotation axis and two circular wheels whose size is such that the outer periphery of the pivot shaft contacts the inner periphery To form a structure that connects the axle ring and the nipping wheel by sandwiching the axle ring into the nipping wheel, and that rotates the nipping wheel with respect to the axle wheel. Thereby, the hinge mechanism of the glasses is formed.

In the present invention, the expressions of the pivot wheel and the holding wheel are used, but they correspond to the top in FIG. The spectacles have a structure in which the temple opens and closes, so there is an image that the royal side is the pivot and the temple side rotates. On the other hand, there is an image that the Axis does not move at the part that becomes the mandrel, so the Axis ring has the image of the rotating wheel on the temple side, and the holding wheel has the image of the rotating wheel on the temple side. It is also possible to have a structure on the yoro side. In eyeglasses, the side to be pinched (pinching ring) and the side to be pinched (axis ring) are relative to each other. Therefore, as shown in (a) and (b) in Fig. 1, which side should be the temple side? Is not a problem. Words should be considered as a signature to distinguish the two. In short, the pivot ring is the side to be inserted by one ring (side to be sandwiched), and the holding ring is composed of two rings and is the side to be sandwiched. The hinge mechanism is constructed by connecting both. .

The axle is made of wire-like (linear) metal (one end of the material that becomes It is a structure that is rounded into a circular shape. The top and bottom of the wheel may be slightly flattened so that it can be inserted into the pinch wheel (of course, it can be used as is). On the other hand, the clamping wheel can be constructed in the following two ways.

One is to combine the two rings to be the holding ring, and to make the two rings together with the end of the eyeglass parts to form a holding ring, and the end of the brazed eyeglass part (oroy or template) is This is a method of forming a structure that will prevent the temple from opening. For this reason, the two rings are prepared in advance as independent parts.

The other method does not require brazing. In this method, one end of an eyeglass part (a metal or a temple) is spirally formed to make two rings, which are used as holding rings. In this method, brazing is not required, and it is not necessary to prepare a ring to be a clamping wheel in advance. The opening angle of the temple is adjusted by bending the end of the spirally wound structure to prevent it from opening. For convenience, the former is referred to as a two-wheeled holding wheel, and the latter is referred to as a helical holding wheel. BRIEF DESCRIPTION OF THE FIGURES

An embodiment of the present invention will be described with reference to the drawings. Fig. 3 is a top view and a cross-sectional view of a pivot ring, Fig. 4 is a two-wheeled holding ring, and Fig. 5 is a helical holding ring. The pivot portion 4 and the holding portion 5 correspond to a royal or a temple, and have a structure that can be either a temple or a royal.

First, in FIG. 3, the pivot portion 4 includes a support shaft 410 and a pivot wheel 420, and the support shaft and the pivot shaft are attached to each other. Of course, the tip of the support shaft may be thinned and the tip may be rounded. However, the outer diameter of the axle is as small as 3iran or less, but the supporting shaft needs to be about 3IM in diameter to maintain a certain level of strength, so brazing is superior in terms of processing smoothness. ing. The two circles with diagonal lines shown in the figure are cross-sectional views taken along the dashed line in the figure on the left, and are circular. The upper part of the axle may be slightly cut off (usually unnecessary) to make it easier to insert into the pinch ring.

FIG. 4 shows a two-wheeled holding wheel, in which a holding wheel A 521 and a holding wheel B 522 constitute a holding wheel 520. Further, the holding wheel 520 is in contact with the support shaft 510, and the contacting part is brazed. If the clamping ring A and the clamping ring B are joined in a slightly separated state, it becomes easier to insert the pivot ring. The holding ring may be a linear member having the same thickness as the support shaft, and the inside diameter of the ring is such that the pivot ring can be inscribed.

FIG. 5 shows a helical holding wheel, in which a tip of a support shaft 510 is spirally wound to form a plurality of wheels A521 and B522, thereby forming a holding wheel 520. In this example, there are two rings, but three or more rings „

A structure in which the layers are overlapped may be used. Due to the spiral made of one wire-like member, the ring A521 and the ring B522 are not on a parallel plane. These rings may be in contact during assembly. The spirally wound structure is more resilient than the case where the wheel is brazed, so even if it is a little tight, the Axis wheel can be pressed into the pinching wheel and inserted. Since the spiral shape is difficult to understand in Fig. 5, a perspective view is shown in Fig. 6.

In addition, the support shaft tip 411 of the pivot portion and the support shaft tip 511 of the holding portion are prevented from opening when the temple is opened (maximum opening is approximately 90 degrees or more, preventing opening). Specifically, Fig. 7 shows how to insert the pivot wheel into the two-wheeled holding wheel, and Fig. 8 shows how it opens and closes (both are views from the side of the wheel, and the dotted lines are cross-sections). It is an invisible part to show that it is a circle.)

When the pivot wheel 420 is inserted between the holding wheel A521 and the holding wheel B 522 in (a) of FIG. 7, the state shown in (b) is obtained. That is, when the Axis wheel is pushed in, the outer ring of the Axis wheel comes into contact with the inner ring of the holding wheel, and each wheel can rotate while sliding. When the supporting shaft 410 of the pivot portion uses a member that is slightly thicker than the pivot wheel 420, even if the lip 413 is narrowed, the distance between the clamping wheel A and the clamping wheel B is equal to that of the pivot shaft. May open slightly before insertion. However, there is no problem with the function as the hinge mechanism.

FIG. 8 shows the open / closed state when the pivot 4 is a temple and the holding portion 5 is a metal. (A) is a state in which the temple (axis 4) is closed, and (b) is a state in which the temple is open. When closed, the tumble end hits the eyeglass frame and further movement is restricted. On the other hand, when it is opened, the support shaft tip 411 of the temple (the pivot 4) hits the support shaft tip 511 of the holoy (holding portion 5), and further movement is restricted. Therefore, the position of the support shaft tip 511 on the holding wheel 520 determines the range of the rotation angle. Since the rotation is relative, the pivot portion in the above description may be a hollow and the holding portion may be a temple.

In the case of a helical clamping wheel, the end of the structure wound spirally is bent to form an open stopper 514 as shown in FIG. 9 because the tip of the support shaft cannot be used to adjust the rotation angle. FIG. 10 is an explanatory view of a case where a hinge with an opening is assembled.

FIG. 11 shows a holding section in which the end of the spirally wound structure is bent to form an opening stopper 514, It is an example of the hinge which consists of the pivot part to which the pivot ring was brazed. FIG. 12 is an explanatory diagram of the combined state.

FIG. 13 shows an example in which the stopper 414 is provided on the pivot. FIG. 14 is an explanatory diagram of the combined state.

FIG. 15 shows rimless glasses using the hinge mechanism of the present invention. In the figure, the holding part 5 is a hollow and the pivot part 4 is a temple. In this example, one end of the holding portion support shaft 5 10 is directly fixed to the lens 6 with a screw 9. The holding wheel 520 is a two-wheeled holding wheel. Since the pivot shaft 420 is sandwiched between the holding wheel 520 and the shaft 520, the finish is finished in a simple and attractive structure. Industrial applicability

The hinge mechanism of the present invention has a simple structure, and is suitable for a frame using a single metal material. For example, it can be processed with only 18K of gold, making it look luxurious. Also, because it does not use screws, it is easy to remove, and you can attach temples of different designs to suit your mood. Simplicity also leads to a lighter frame.

The axle is held by the elastic force of the pinch ring (panel force), and it is not held down by any other parts, so if an excessive force is applied to the glasses (especially temples), the axle ring will be pinched. The main eyeglass parts are not damaged because they come off. In the case of a spirally wound structure, it is possible to increase the coupling force of the hinge by winding the structure three or more times.
