Description
【考案の詳細な説明】 本考案は、トーンアームの軸受構造に関する。[Detailed explanation of the idea] The present invention relates to a bearing structure for a tone arm.
レコードプレーヤにおいて、トーンアームアセンブリを
取り付ける場合、アームスタンドと称されるのか゛一般
に用いられている。When attaching a tone arm assembly to a record player, an arm stand is generally used.
このアームスタンドがネジ等の固定手段によりパネルに
固定されて１〜−ンアームアセンブリを保持してトーン
アームの軸受構造を構成している。This arm stand is fixed to the panel by fixing means such as screws, holds the first arm assembly, and constitutes a bearing structure for the tone arm.
かかる軸受構造においては、アームスタンドをパネルに
固定する場合にアームスタンドの位置ずれが生じ易く、
又ネジで締付けることにより不要な外力が加わってパネ
ルの強度が低下するという欠点があった。In such a bearing structure, when the arm stand is fixed to a panel, the position of the arm stand is likely to shift.
Furthermore, tightening with screws has the disadvantage that unnecessary external force is applied and the strength of the panel is reduced.
本考案の目的は、上記した欠点を解消したトーンアーム
の軸受構造を提供することである。An object of the present invention is to provide a tone arm bearing structure that eliminates the above-mentioned drawbacks.
以下、本考案を添付図面を参照して詳細に説明する。Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
第１図は、本考案によるレコードプレーヤの軸受構造の
一実施例の断面図であり、第２図に第１図の平面図が示
されている。FIG. 1 is a sectional view of an embodiment of a bearing structure for a record player according to the present invention, and FIG. 2 is a plan view of FIG. 1.
図において、１は円筒状の軸受部材であり、パネル２の
両面において例えば樹脂成形されているために固定手段
を用いなくてもパネル２に確実に固定され、よって位置
ずれを生じない。In the figure, reference numeral 1 denotes a cylindrical bearing member, which is molded, for example, with resin on both sides of the panel 2, so that it is securely fixed to the panel 2 without using any fixing means, so that no displacement occurs.
この軸受部材１を樹脂成形する場合は、予め形成された
所望形状の型枠に樹脂を充填すべく溶融樹脂を流し込む
ためのいわゆるランナーか゛用いられるか゛、成形後は
このランナーにおいてもその形状が樹脂成形される。When molding the bearing member 1 with resin, a so-called runner is used to pour the molten resin into a preformed mold having a desired shape. molded.
本考案は、このランナーにおいて形成された樹脂部を軸
受部材１及び該軸受部材１が設けられた近傍のパネル２
の強度を増大するための脚部材３として用いたものであ
る。The present invention uses the resin portion formed in this runner as a bearing member 1 and a panel 2 in the vicinity where the bearing member 1 is provided.
This is used as a leg member 3 to increase the strength of.
従って、軸受部材１を成形する場合、例えば４本のラン
ナーを放射線状に配置し、更に該ランナーと対向するノ
々ネル２の任意の位置に複数の孔４を設けて溶融樹脂を
流し込んで成形することにより４本の脚部材３ａ、３ｂ
、３Ｃ，３ｄが軸受部材１と一体に成形され、又パネル
２の孔４に該脚部材の一部が嵌入して固定部５が形成さ
れる。Therefore, when molding the bearing member 1, for example, four runners are arranged in a radial pattern, and a plurality of holes 4 are provided at arbitrary positions of the nononel 2 facing the runners, and molten resin is poured into the holes 4 to form the bearing member 1. By doing so, the four leg members 3a, 3b
, 3C, and 3d are integrally molded with the bearing member 1, and a portion of the leg member is fitted into the hole 4 of the panel 2 to form the fixing portion 5.
この固定部５により脚部材３ａ、３ｂ、３Ｃ，３ｄがパ
ネル２に確実に固定されるためにパネル２の強度が増大
する。Since the leg members 3a, 3b, 3C, and 3d are reliably fixed to the panel 2 by the fixing portions 5, the strength of the panel 2 is increased.
また、軸受部材１及びパネル２の強度を更に増大するた
めに上記脚部材３ａ、 ３ｂ、 ３Ｃ，３ｄを例え
ば軸受部材１と同心円状に連結した例えば２本の補助部
材６ａ、６ｂが形成されている。Further, in order to further increase the strength of the bearing member 1 and the panel 2, for example, two auxiliary members 6a, 6b are formed by connecting the leg members 3a, 3b, 3C, 3d concentrically with the bearing member 1. There is.
この補助部材６ａ、６ｂは、軸受部材１を成形する時に
軸受部材１と同心円状のランナーを用いることにより容
易に成形される。The auxiliary members 6a, 6b are easily molded by using a runner concentric with the bearing member 1 when molding the bearing member 1.
また、ランナーと対向するパネル２の任意の位置に複数
の孔４を設けることにより前述と同様に固定部が形成さ
れて補助部材６ａ、６ｂがパネル２に確実に固定される
ためにパネル２の強度が増大する。Further, by providing a plurality of holes 4 at arbitrary positions of the panel 2 facing the runner, a fixing part is formed in the same manner as described above, and the auxiliary members 6a and 6b are reliably fixed to the panel 2. Strength increases.
以−Ｌ詳述した如く、本考案によるトーンアームの軸受
構造によれば、パネルへの取付部材の位置ずれが生じな
く、また軸受部材及びパネルの強度が増大する。As described in detail below, the tone arm bearing structure according to the present invention prevents displacement of the mounting member to the panel, and increases the strength of the bearing member and the panel.
