この考案はピアノの下部に取付けられるキャスターに関
する。[Detailed description of the invention] This invention relates to casters attached to the lower part of a piano.
例えば、従来のアップライトピアノにお・いては、第１
図および第２図に示すようにキャスターが取付けられて
いる。For example, in a conventional upright piano, the first
Casters are attached as shown in the figure and FIG.
すなわち、キャスター１は、ねじ取付孔を有する取付板
２と、その下面に支持体を介して回転自在に取付けられ
た車輪３とから構成されており、アップライトピアノの
腕木４お・よび前土台５の下端に、取付板２を当てて下
方から木ねじ６を締付けることにより取付けられている
。That is, the caster 1 is composed of a mounting plate 2 having a screw mounting hole and a wheel 3 rotatably mounted on the lower surface of the mounting plate 2 via a support, and the caster 1 is composed of a mounting plate 2 having a screw mounting hole and a wheel 3 rotatably mounted on the lower surface of the mounting plate 2 via a support. It is attached by applying the mounting plate 2 to the lower end of the frame 5 and tightening the wood screws 6 from below.
ところがこの場合、木ねじ６をねじ込む相手部分は腕木
４の方が木口であり、また前土台５の方が木端部である
ため、取付は強度が弱いという問題がある。However, in this case, the arm 4 has a wood end and the front base 5 has a wood end to which the wood screw 6 is screwed, so there is a problem that the mounting strength is weak.
このため、腕木４の木口部分に端嵌（図示せず）を取付
けたり、腕木４の内側に何本７を取付けたりし、また前
土台５の芯を７トア等の硬い木材にして補強し、木ねじ
６の締付は強度のアップを図っている。For this purpose, end fittings (not shown) are attached to the ends of the arms 4, several pieces 7 are attached to the inside of the arms 4, and the core of the front base 5 is reinforced with hard wood such as 7-tore. , the tightening strength of the wood screws 6 is increased.
しかしながら、このようにして取付けられたキャスター
にあっては、キャスター取付部に余分な部材を取付けな
ければならず、その外業が面倒であるとともに部品点数
が増加し強度的にも不充分であるという欠点があった。However, with casters installed in this way, extra members must be attached to the caster attachment part, which is troublesome for outside work, increases the number of parts, and is insufficient in terms of strength. There was a drawback.
この考案は上記事情に鑑みてなされたもので、例えばア
ップライトピアノの下部のように、取付対象箇所が平面
視した場合り字状をなす二つの起立板部（腕木お・よび
前土台に相当）の下端である場合、その起立板部の下面
すなわち腕木の木口や前土台の木端部ではなく、それら
の内側面部に木ねじで取付けることができ、しかもその
取付部分の角部を補強することができ、充分強固な取付
は強度を保てるようにしたピアノ用キャスターを提供す
ることを目的とする。This idea was made in view of the above circumstances.For example, in the lower part of an upright piano, the installation target part has two upright plate parts (corresponding to the arms and front base) that form a dovetail shape when viewed from above. ), the lower end of the upright board, i.e., the end of the arm or the wood end of the front base, can be attached with wood screws to the inside surface of the board, and the corner of the mounting part must be reinforced. The purpose of the present invention is to provide a caster for a piano that can be mounted with sufficient strength and maintain strength.
この考案はその目的を遠戚するため、取付金具を、起立
板部の内側面に当接させられて取付ねじによってその内
側面に固定されるＬ字状の側板部ど、この側板部下端に
設けられた底板部と、側板部の外側方向に突出するよう
底板部と一体に固定的に形成され上面に前記起立板部下
面が当接せしめられる延出片とから構成し、この延出片
の下面に車輪を取付けた点に特徴を有する。This invention is distantly related to that purpose, so the mounting bracket is attached to the lower end of the side plate, such as an L-shaped side plate that is brought into contact with the inner surface of the upright plate and fixed to the inner surface with a mounting screw. It is composed of a bottom plate provided and an extending piece fixedly formed integrally with the bottom plate so as to protrude outwardly from the side plate, and the lower surface of the upright plate is brought into contact with the upper surface of the extending piece. It is distinctive in that wheels are attached to the underside of the machine.
以下、この考案を図面を参照して説明する。This invention will be explained below with reference to the drawings.
第３図はこの考案の一実施例を示し、１０は取付金具で
あって、底板部１１お・よびそれに垂直に立設され互い
に直交しＬ字状をなす二つの側板部１２゜１３とからな
り、一枚の板状部材により折曲形成されている。FIG. 3 shows an embodiment of this invention, and 10 is a mounting bracket, which is comprised of a bottom plate part 11 and two side plate parts 12 and 13, which are vertically erected thereto and are orthogonal to each other and form an L-shape. It is formed by bending a single plate-like member.
すなわち、底板部１１に対して垂直上方に折曲されて第
１の側板部１２が形成され、この第１の側板部１２に対
して水平方向に直角に折曲されて第２の側板部１３が形
成されている。That is, the first side plate part 12 is formed by bending vertically upward with respect to the bottom plate part 11, and the second side plate part 13 is formed by bending the first side plate part 12 at right angles in the horizontal direction. is formed.
第７図にこの取付金具１０を展開したブランクの形状を
示す。FIG. 7 shows the shape of a blank in which this mounting bracket 10 is developed.
取付金具１０は、フラットな一枚の板状部材を第７図中
の二点鎖線に沿ってプレス加工により折曲しかつ第３図
に示すＷの箇所を溶接することによって形成されている
。The mounting bracket 10 is formed by bending a flat plate-like member by press working along the two-dot chain line in FIG. 7, and welding it at the point W shown in FIG. 3.
なお、この場合、底板部１１には切り込み部１４が設け
られており、両側板部１２゜１３の外側に底板部１１の
縁が延出片１１ａ、 ｌｌｂとして一体的に突出されて
いる。In this case, the bottom plate part 11 is provided with a notch part 14, and the edges of the bottom plate part 11 are integrally projected outside the side plate parts 12 and 13 as extension pieces 11a and llb.
そして、前記切り込み部１４のない側の延出片１１ｂの
下面に、支持体１５を介して回転自在に車輪１６が取付
けられている。A wheel 16 is rotatably attached to the lower surface of the extending piece 11b on the side where the notch 14 is not provided via a support 15.
この場合、もちろん支持体１５は取付金具１０に対して
水平方向に回転自在に取付けられており、車輪の向きは
自由に変わるようになっている。In this case, of course, the support body 15 is attached to the mounting bracket 10 so as to be freely rotatable in the horizontal direction, so that the direction of the wheels can be freely changed.
また、前記各側板部１２．１３にはねじ取付孔１７がそ
れぞれ４個ずつ設けられており、この両側板部１２．
ｉ３を取付対象箇所の隅部に当てて取付けるようになっ
ている。Further, each side plate portion 12.13 is provided with four screw mounting holes 17, respectively.
The i3 is installed by placing it against the corner of the target location.
ここで、このキャスターを例えばアップライトピアノの
下部に取付ける場合について述べると、第４図〜第６図
に示すように、前土台５と腕木４の交わる隅部に、取付
金具１０の側板部１２．１３を下から入れて前土台５と
腕木４の内側面に前記両側板部１２．１３を当て、そし
て底板部１１に形成した延出片１１ａ、 ｌｌｂを前土
台５と腕木４の下端面に当接させて、木ねじ１８を側板
部１２．１３のねじ取付孔１７から前土台５および腕木
４の内側面部にねじ込んでキャスターを固定する。Now, to describe the case where this caster is attached to the lower part of an upright piano, for example, as shown in FIGS. 4 to 6, the side plate part 12 of the mounting bracket 10 is 13 from below and apply the both side plate parts 12.13 to the inner surfaces of the front base 5 and the arm 4, and then insert the extending pieces 11a and llb formed on the bottom plate 11 into the lower end surfaces of the front base 5 and the arm 4. The casters are fixed by screwing the wooden screws 18 into the inner side surfaces of the front base 5 and the arms 4 through the screw attachment holes 17 of the side plate parts 12.13.
このように、この考案のキャスターは、取付金具を、取
付対象箇所のＬ字状をなす二つの起立板部の内側面に当
接させられて取付ねじによってその内側面に固定される
Ｌ字状の側板部と、この側板部下端に設けられた底板部
と、側板部の外側方向に突出するよう底板部と一体に固
定的に形成され上面に前記起立板部下面が当接せしめら
れる延出片とから構成し、この延出片の下面に車輪を取
付けたものであるから、例えばアップライトピアノの下
部に取付ける場合、腕木や前土台の下端面ではなく内側
面部にねじ止めすることができる。In this way, the caster of this invention has an L-shaped structure in which the mounting bracket is brought into contact with the inner surfaces of the two L-shaped upright plates at the mounting location and fixed to the inner surfaces with the mounting screws. a side plate part, a bottom plate part provided at the lower end of the side plate, and an extension fixedly formed integrally with the bottom plate part so as to protrude outwardly of the side plate part, the upper surface of which the lower surface of the upright plate abuts. Since the wheel is attached to the lower surface of this extending piece, for example, when installing it to the lower part of an upright piano, it can be screwed to the inner side surface of the arm or front base instead of the lower end surface. .
したがって、腕木に端嵌や材木を取付ける必要はなく、
また前土台をマトア芯にする必要もなく、強固に取付け
ることができる。Therefore, there is no need to attach end fittings or lumber to the arms,
Also, there is no need to make the front base a matoa core, and it can be installed firmly.
しかもこの場合、Ｌ字状の側板部を取付対象箇所の隅部
に挿入して固定するようにしているので、その隅部を補
強することができる。Moreover, in this case, since the L-shaped side plate portion is inserted and fixed into the corner of the attachment target location, the corner can be reinforced.
また、取付金具の延出片上面に腕木や前土台の下端面を
当接するようになっているので、アップライトピアノの
荷重を側板部だけでなく底板部でも受けることができ、
荷重が無理にかかるのを防止できる。In addition, since the upper surface of the extending piece of the mounting bracket contacts the lower end surface of the armrest and front base, the load of the upright piano can be received not only by the side panels but also by the bottom panel.
It can prevent the load from being applied too much.
しかも、この考案のキャスターは、車輪を、荷重を受け
る延出片の下面に取付けているので、荷重が無理なく車
輪にかかり、特に荷重の大きいピアノを支えるだけに、
安定した支持力を発揮することができる。Moreover, the casters of this invention have the wheels attached to the lower surface of the extended piece that receives the load, so the load is easily applied to the wheels, and it is especially useful for supporting pianos with heavy loads.
It can exhibit stable supporting force.
