本発明は、テンプルの芯金が離脱し難くい合成
樹脂製の眼鏡用耳掛パツドを工業的に量産できる
新方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a new method for industrially mass-producing eyeglass ear hook pads made of synthetic resin in which the core metal of the temple is difficult to separate.

Since the ear hooks of glasses come into direct contact with the skin, there are restrictions on the materials that can be used. For example, with metal frame glasses, if the metal temples are in direct contact with the skin, they will slip easily and will not feel stable when worn, and the metal will react with sweat, causing skin irritation. There are problems if you wake up or have allergies. For this reason, synthetic resin ear pads called "Modern" are usually attached to the ear pads of the eyeglass temples, which are in close contact with the skin for a long period of time.

た。 However, the ear pads made of synthetic resin tend to slip on metal, and if the core diameter of the temple and the core hole of the ear pads do not match, there is a risk that they may fall off during use. Therefore, in the past, while devising the shape and material of the temple, it was necessary to match the core diameter of the temple part to be inserted into the ear pad and the core hole of the ear pad, so the temple core diameter and pad core were The specifications of the holes have become too diverse, leading to an increase in the inventory burden on the companies concerned.

を提供することを技術的課題とするものである。 The present invention has been made in view of the above-mentioned problems with conventional eyeglasses, and has core holes of different diameters that are stably fixed to the temples and do not come off inadvertently, regardless of the material of the temples. The technical objective is to provide a new method that can efficiently mass-produce synthetic resin ear pads.

にした点に要旨がある。 That is, the present invention provides a synthetic resin molded article 1 which is injected into the cavity of a mold C and is in a heated semi-fluid state.
has a large diameter part I 1 , I 2 and a small diameter part I 3 , and the large diameter part I 1 , I 2
A tapered insert fitting I of different diameter is inserted between the and narrow diameter portion I3 , and when the synthetic resin molded article 1 enters a thermally flexible state in the process of curing,
By adopting the processing means of pulling out and removing the insert metal fitting I, the large diameter hollow portion 2
1 and 22, and the boundary area between the large diameter cavities 21, 22 and the small diameter cavity 23 is a synthetic resin having a temple core hole 2 that can form tapers 24, 24. The main point is that it is possible to obtain ear pads of the molded body 1'.
以下、本発明を添附図面に示す実施例に基いて
説明する。
Hereinafter, the present invention will be explained based on embodiments shown in the accompanying drawings.

いる。 First, the temperature inside the cavity of mold C is about 200℃.
A synthetic resin molded article 1 is obtained by injecting a molten pyropionic acid fiber resin heated to a temperature of . While this synthetic resin molded body 1 is still in a semi-fluid state heated to about 180°C, a small diameter portion I is formed between the large diameter portions I 1 and I 2 from the small end of the synthetic resin molded body 1. 3. Insert the different diameter insert fitting I by driving it in the axial direction. Note that the different diameter insert fitting I is tapered between the large diameter portions I 1 , I 2 and the narrow diameter portion I 3 .

孔２が形成される。 The synthetic resin molded body 1 into which the different diameter insert fitting I is inserted progresses in hardening as the temperature decreases, but when the temperature drops to about 110° C., the molded body 1 becomes thermoplastic. Therefore, when the insert metal fitting I of different diameter is pulled out, the synthetic heavy molded body 1, which is in a heated and flexible state, is temporarily deformed elastically by the banded rubber elasticity, and the insert metal fitting I can be pulled out easily. The molded body 1' has a small diameter cavity 23 between the large diameter cavities 21 and 22, and the boundary area between the large diameter cavities 21, 22 and the small diameter cavity 23 has a taper 24, A temple core hole 2 having a diameter of 24 is formed.

テンプル３と耳掛パツドとは安定に定着して一体
化されることになる。 Thus, when the ear pad molded as described above is cooled to room temperature and hardened, when the core part of the temple 3 is inserted into the core hole 2, the temple 3 and the ear pad are stably fixed. and will be integrated.
この場合において、テンプルの金属材質が合成

当該耳掛パツドの細径空洞部２３は芯孔全長に比

スツポリと挿入することができる。 In this case, even if the metal material of the temple is difficult to slip due to the synthetic resin material,
Since the narrow diameter hollow portion 23 of the ear hook pad is shorter than the entire length of the core hole, it can be inserted smoothly and completely by pushing in a little forcefully.
逆に、テンプルの金属が耳掛パツドを構成する

耳掛パツドにおける細径空洞部２３が芯金を締め

耳掛パツドに安定に定着することになる。 On the other hand, if the metal of the temple is slippery against the synthetic resin that makes up the ear pad, the small diameter cavity 23 of the ear pad will tighten the core metal, so in this case as well, the temple will be stably fixed on the ear pad.

As explained above with the embodiments, according to the method of the present invention, a small diameter cavity is provided between the large diameter cavity and the large diameter cavity, and the large diameter cavity and the small diameter cavity are connected to each other. It becomes possible to efficiently mass-produce ear pads having a temple core hole whose boundary region can be tapered. Therefore, the ear pad manufactured by the method of the present invention has a property of not slipping easily even if the metal material forming the temple has a slippery property with respect to the synthetic resin material forming the ear patch. However, if the core diameter of the temple is even slightly thicker than the small diameter cavity, it can be stably fixed, and there is no need to prepare and stock many types of ear hook pads for each temple.
