Abstract

PURPOSE:To assemble a frame without employing brazing by separating the frame into an upper groove part and a lower groove part and coupling the joining parts of the upper and lower groove parts by a mechanical coupling method. CONSTITUTION:The spectacles frame consists of the upper groove part 1 and a couple of the lower groove part 2, and the upper groove part 1 is constituted by connecting top rim parts 4 and 4 to both ends of a bridge 3, and forming one of members 5 of a hinge at one end part of each top rim part 4. When the lower groove parts 2 are coupled with the upper groove part 1, tubes 9 and 10 at both ends of each lower groove part 2 are fitted to the reverse surface of the bridge 3 and one member 5 of the hinge, the overlap parts are fixed by clamping with screws 12, and a lens 6 is held between the top rim part 4 and lower groove part 2. Consequently, brazing is unnecessary when the frame is assembled, and the frame is assembled efficiently and easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eyeglass frame, and more particularly to a metal eyeglass frame that can be assembled without the need for brazing.

The basic structure of the m-mirror frame is that a pair of lens frames on both sides are connected at the peaks, and temples are attached to the outer edges of both lens frames with hinges.
In the 'Jh case, a blower is installed to assemble the lens frame.

By the way, in the case of a metal frame, the lens frame, crest,
Connection with a mating part 44 such as a hinge or blow tip is performed by brazing.

However, if the brazed parts are close to each other, for example, when a blow tip is attached to the lens frame and a hinge endpiece is brazed to the blow tip, heat will spread to the part that was brazed first. In addition, due to differences in temperature characteristics depending on the material of the silver solder, separation of the solders may occur, making it extremely difficult to assemble the frame. This kind of brazing separation is not limited to blowing and end fittings, but applies to all brazing processes.

In addition, titanium is the most suitable material for metal frames because it is lightweight and has excellent corrosion resistance, elasticity, and strength, but titanium is expensive because it cannot be brazed to the front car in the atmosphere. There is a problem in that equipment investment is required and the manufacturing cost of the frame is high.

Furthermore, it is well known that the strength of brazed parts made of titanium decreases over time, and from this point of view, it has become necessary to reconsider the Loey J structure.

This invention was made in view of the above points, and it is possible to assemble a frame with excellent strength without the need for brazing, and the use of titanium can be used for special equipment.
The first objective is to provide an eyeglass frame that can be realized without the need for.

The structure of the present invention is such that the frame is separated into an upper groove part and a lower groove part, and the connecting part of the lower part and the lower groove part is connected by a mechanical connecting means, thereby eliminating the need for a rowi J in assembling the frame. be.

Hereinafter, the present invention will be explained based on embodiments shown in the accompanying drawings.

As shown in FIG. 1, the eyeglass frame of the present invention is composed of an upper groove part 1 and a pair of lower groove parts 2. It is constructed by connecting one side part 5 of a hinge to the end of .4.

The above-mentioned upper groove part 1 is made by using a continuous metal deformed wire, round wire, plate material, or square material, and by pressurizing, cutting, and drilling, the peak part 3, the eyebrows 4.4, and one side of the hinge are removed. The eyebrows 4, 4 and 5 have a fitting groove 7 for the lens 6 on the inner periphery, and a concave-convex pattern 8 on the rear surface of the rm and the second surface as shown in FIG. You may also apply

The pair of lower grooves 2.2 are formed in a half-frame body circumscribing the outer periphery of the lower half of the lens, and opposing blow holes 9.10 protruding outward are provided at both ends thereof either integrally or by welding. .

This lower groove part 2.2 is also formed by pressing, cutting, or drilling using a single metal wire, plate, or square material, and a lens fitting groove 11 is provided on its inner peripheral surface. In addition,
Both the second groove part 1 and the lower groove part 2 may be manufactured by casting.

The connection of the lower groove part 2.2 to the upper groove part 1 is done mechanically, eliminating the need for brazing. 5, and the 1415-minute overlap is fixed by tightening screws 12, so that the shield part 3 and the lower groove part 2 hold the lens 6.

In order to improve the bonding strength between the upper groove part 1 and the lower groove part 2 and to stably hold the lens, in the case shown in the figure, a blow tip 9 is attached to the lower surface of the crest 3 and the lower surface of one side part 44' of the hinge 44'5. and 10 are provided with four fitting parts 13, and the peak part 3 and the blow tip 9 are provided.
As shown in FIG. 3, the tip of the screw 9 that connects the two is caulked with a punch or the like to prevent loosening.

Further, at the fitting portion between the four parts 13 and the blow tip 9 or 10, a pin 14 is provided on one side and a hole 15 into which the pin 14 is fitted is provided on the other side.

In addition, when installing the temple 16 that is aligned with the upper groove part 1, the hinge part 4# of the hinge provided in the iA part of the temple 16 is
17 can be connected to one member 5 with a screw 18, and one side v
IS 5 forms the armour.

The frame of this invention has a t14 structure as described in 1.
For example, the upper groove part 1 and the lower groove part 2 are manufactured using titanium, aluminum, or other metal wire, and they are joined by tightening and caulking the screws 12, and the temple 16 is attached with a hinge, and the frame is assembled and the lens is attached. Install on one side of the hinge 4
All you have to do is loosen screw 12 of 45 and blow 10.

As described above, according to the present invention, since it has the configuration as described in item 1, it has the following effects.

(1) Since the frame is separated into an upper groove portion and a lower groove portion, and the two are connected by mechanical connection means, there is no need for brazing at all in assembling the frame, and frame assembly can be performed extremely efficiently and easily.

(2) No brazing is required when assembling the frame, so
By using titanium, which is difficult to braze, as a filler material, a simple O-frame can be constructed without requiring special equipment, and the manufacturing cost of a frame using titanium can be significantly reduced.

(3) Separate the frame into upper and lower grooves)ill: Therefore, by changing the lower groove, you can create various models, and even if you have a specific upper groove, you can add color, plating, cloisonné, etc. to the lower groove. Many variations can be made by applying surface treatment.

(4) No brazing is required when assembling the frame, so
The assembly strength is greatly improved.
