Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は、プラスチック中空パネルにより構成された電子楽器用のスタンドに 関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a stand for an electronic musical instrument, which is composed of a plastic hollow panel.
（従来の技術） 従来、使用されている電子楽器用スタンドは木工品、或いは鉄パイプ等が広く 用いられており、これらでは重いという問題点があり、これらの代替品として、 ブロー成形や射出成形等によるプラスチック化は容易に考え得るところであるが 、プラスチック単体で用いる場合には、荷重強度の不足や、中空体による楽器音 との共振、共鳴など従来品に劣る欠点を有しており、これを解決する手段は容易 でないのが実状である。(Prior Art) Conventionally, the stands for electronic musical instruments that have been widely used are wood products, iron pipes, etc., and they have the problem of being heavy. As alternatives to these, blow molding and injection molding are used. Although it can easily be considered to be made plastic by such as, etc., when it is used alone, it has drawbacks that are inferior to conventional products such as insufficient load strength, resonance with the instrument sound due to the hollow body, and resonance. The reality is that the means to solve the problem is not easy.
一般的に平板中空パネルの補強方法は、リブの施設や補強材のインサート、ア ウトサート方法などが知られているが、成形方法や設備が複雑になり、外観を損 なう場合も多く、限定的に使用されるのが通例であった。 Generally, as a method of reinforcing flat plate hollow panels, rib facilities, reinforcement inserts, and outsert methods are known.However, the molding method and equipment are complicated and the appearance is often impaired. It was customarily used.
（考案が解決しようとする課題） 本考案は、上記問題点を解決するためになされたものであり、その目的とする ところは、パイプフレームと成形品の特性を利用した構造との組合せによって、 より剛性の高い、かつ共振、共鳴を起さない電子楽器用スタンドを提供しようと するものである。(Problems to be Solved by the Invention) The present invention has been made to solve the above-mentioned problems, and an object thereof is to combine a pipe frame and a structure utilizing the characteristics of a molded product with each other. The present invention aims to provide a stand for electronic musical instruments that has higher rigidity and does not cause resonance or resonance.
（課題を解決するための手段） 上記目的を達成するために、本考案の電子楽器用スタンドにおいては、プラス チックのブロー成形により構成された中空スタンドで、それぞれの平板面に２条 の帯状リブを施し、一方の平板面帯状リブの中間部に分散、独立した少なくとも １つの凹突起を設け、該凹突起と相対向する平板面とによって画成された中空部 にパイプフレームを挿入すると共に、該凹突起先端の形状を該パイプフレーム平 断面形状と相似形とにすることにより、該パイプフレームを所定の位置に確実に 装着したものである。(Means for Solving the Problem) In order to achieve the above object, in the electronic musical instrument stand of the present invention, a hollow stand formed by plastic blow molding is used, and two strip-shaped ribs are provided on each flat plate surface. At least one concave protrusion dispersed and independent is provided in the middle portion of one flat plate-shaped rib, and the pipe frame is inserted into the hollow portion defined by the concave protrusion and the flat plate surface facing each other. By making the shape of the tip of the concave projection similar to the plane cross-sectional shape of the pipe frame, the pipe frame is securely mounted at a predetermined position.
（作 用） 上記のような構成により、パイプフレームの有する剛性をプラスチックの中空 体に付与してスタンドの横揺れに対する減衰効果を生じさせるので中空体として の性質である共振、共鳴の発生を減少させることができる。(Operation) With the above configuration, the rigidity of the pipe frame is added to the plastic hollow body to produce the damping effect against the roll of the stand, so the occurrence of resonance and resonance, which are the properties of the hollow body, is reduced. Can be made.
（実施例） 以下、図面によって本考案の一実施例を説明する。Embodiment An embodiment of the present invention will be described below with reference to the drawings.
第１図乃至第３図中、１は全体をプラスチックにてブロー成形された中空構造 の電子楽器用スタンドであり、このスタンド１の両側平板面１ａ、１ｂに２条の 帯状のリブ２を設け、帯状リブ２は平板面１ａ、１ｂを分割してそれぞれの平板 面１ａ、１ｂの弾性強度の向上を計っている。帯状リブ２の間で形成された平板 面４ａの中央部に分散、独立した複数個の凹突起３を設け、凹突起３の先端部３ ａにはパイプフレーム５の半径弧の同心円弧を形成し、パイプフレーム５はスタ ンド１の上面部１ｃに設けた開口部７より挿入され、開口部７はキャップ６によ り密閉されている。 1 to 3, reference numeral 1 denotes a stand for an electronic musical instrument having a hollow structure which is entirely blow-molded with plastic, and two strip-shaped ribs 2 are provided on both flat plate surfaces 1a and 1b of the stand 1. The strip-shaped rib 2 divides the flat plate surfaces 1a and 1b to improve the elastic strength of the flat plate surfaces 1a and 1b. A plurality of dispersed and independent concave projections 3 are provided in the central portion of the flat plate surface 4a formed between the strip-shaped ribs 2, and concentric circular arcs of the radial arc of the pipe frame 5 are formed at the tip end 3a of the concave projections 3. The pipe frame 5 is inserted through the opening 7 provided in the upper surface 1c of the stand 1, and the opening 7 is sealed by the cap 6.
パイプフレーム５は平板面４ｂと凹突起３の先端部３ａとで画成されている中 空部に挿入され、かつブロー成形により圧入嵌合される。 The pipe frame 5 is inserted into the hollow portion defined by the flat plate surface 4b and the tip portion 3a of the concave projection 3 and is press-fitted by blow molding.
即ち、凹突起３が板面外側に変形し、嵌合状態が緊密になる。凹突起３の先端 部３ａの作用は挿入されたパイプフレーム５の位置を保持し、揺動などを防止し 、更に凹突起３を複数個（図では５個）に分散することにより、凹突起３間の平 板面４ａにより、それぞれの凹突起３は外側への変形量が自由となり、成形品肉 厚３ｔがバラついてもパイプフレーム５との嵌合の密着性を維持することができ る。 That is, the concave projection 3 is deformed to the outside of the plate surface, and the fitted state becomes tight. The action of the tip portion 3a of the concave projection 3 holds the position of the inserted pipe frame 5 to prevent rocking and the like, and further disperses the concave projection 3 into a plurality (five in the figure), Due to the flat plate surface 4a between the three, the amount of deformation of each concave projection 3 can be set freely, and even if the wall thickness 3t of the molded product varies, the fitting tightness with the pipe frame 5 can be maintained. .
（考案の効果） 本考案は前述のように全体をプラスチックの中空体で成形して、帯状リブとそ の中間部に複数個の凹突起を形成してなる電子楽器用スタンドで、中空部をパイ プフレームを挿入する空間とし、スタンド内面の平面部と対面側に設けた凹突起 内面との間で生じる弾性効果を利用し、パイプフレームと中空成形体との緊密な 密着性を得ることができる。即ち、パイプフレームの有する剛性をプラスチック の中空体に付与してスタンドの横揺れに対する減衰効果を生じさせるので中空体 としての性質である共振、共鳴の発生を減少させることができる。(Effect of the Invention) As described above, the present invention is an electronic musical instrument stand in which the whole is molded by a plastic hollow body, and a plurality of concave projections are formed in the intermediate portion of the band-shaped rib. A space for inserting the pipe frame is used, and by utilizing the elastic effect that occurs between the flat surface of the stand inner surface and the inner surface of the concave protrusion provided on the opposite side, it is possible to obtain close adhesion between the pipe frame and the hollow molded body. it can. That is, since the rigidity of the pipe frame is imparted to the hollow plastic body to produce a damping effect on the rolling of the stand, resonance and resonance, which are properties of the hollow body, can be reduced.
