Description

バーベル用ダンベル取付け金具、及びダンベル取付け金具を具備するバーベルシャフトDumbbell mounting bracket for barbell and barbell shaft provided with dumbbell mounting bracket
　本発明は、バーベル用ダンベル取付け金具、及びダンベル取付け金具を具備するバーベルシャフトに関する。 The present invention relates to dumbbell fittings for barbells and barbell shafts equipped with dumbbell fittings.
　従来、シャフトの両端にダンベルを取り付けてバーベルとして使用できるものが知られている（例えば特許文献１、２、３に記載の技術）。 Conventionally, it is known that dumbbells can be attached to both ends of a shaft and used as a barbell (for example, the techniques described in Patent Documents 1, 2, and 3).
　上述のバーベルの従来技術では、中央のシャフトとダンベルのシャフトとを同軸上で一直線となるように、中央のシャフトの両端にダンベルを連結している。その連結方法としては、中央のシャフトの両端に切った雌ネジ穴にダンベルの少なくとも一方のウエイト部分から伸びる雄ネジシャフトをねじ込む方法又はその逆（例えば特許文献１、３参照）、或いは、中央のシャフトの両端に取り付けたボルト付き雌穴にダンベルの少なくとも一方のウエイト部分から伸びるシャフトを差し込んでボルトで固定する方法（例えば特許文献２参照）などが採用されている。 In the conventional barbell technology described above, the dumbbells are connected to both ends of the central shaft so that the central shaft and the dumbbell shaft are coaxially aligned. As a connection method, a male screw shaft extending from at least one weight portion of the dumbbell is screwed into female screw holes cut at both ends of the central shaft, or vice versa (see, for example, Patent Documents 1 and 3), or A method of inserting a shaft extending from at least one weight portion of a dumbbell into a female hole with a bolt attached to both ends of the shaft and fixing it with a bolt is adopted (for example, see Patent Document 2).

　上述のバーベルの従来技術では、ダンベルの少なくとも一方のウエイト部分からシャフトを伸ばす、又はウエイト部分に雌ネジの穴を切る必要があった。従って、バーベルシャフトとダンベルは互いに連結できる構造を有したセットとして提供する必要があった。 With the conventional barbell technology described above, it was necessary to extend the shaft from at least one weight portion of the dumbbell, or to cut a female screw hole in the weight portion. Therefore, it is necessary to provide the barbell shaft and the dumbbell as a set having a structure that allows them to be connected to each other.
　ここで、個人の運動愛好家は、一般的にはまず手軽なダンベルを購入し、その後にバーベルなどの本格的な運動器具の購入に進む場合が多い。しかしながら、一般的なダンベルを先に購入してしまった場合に、上述の従来技術に見られるようなバーベルを購入しようとした場合に、先に購入したダンベルは連結することができないため、結局専用のダンベルを購入し直さねばならないか、或いは、大きな円形ウエイトを備えた一般的なバーベルを購入しなければならなかった。 Here, individual exercise enthusiasts generally purchase simple dumbbells first, and then proceed to purchase full-fledged exercise equipment such as barbells. However, if you purchase general dumbbells first and try to purchase the barbells seen in the above-mentioned prior art, the previously purchased dumbbells cannot be connected, so after all I had to buy new dumbbells, or buy regular barbells with large circular weights.
　このため、金銭的に無駄が生じるほか、増えたダンベルや円形ウエイトの置き場所又は保管場所が必要となり、一般の家庭ではそのスペースの確保が難しい場合があるという課題があった。 As a result, in addition to being financially wasteful, additional dumbbells and circular weights need to be placed or stored, and there is a problem that it may be difficult for ordinary households to secure such space.
　そこで、本発明は、一般的なダンベルを連結することができるバーベル用ダンベル取付け金具、及びダンベル取付け金具を具備するバーベルシャフトを提供することを目的とする。 Accordingly, an object of the present invention is to provide a dumbbell mounting bracket for a barbell to which a general dumbbell can be connected, and a barbell shaft equipped with the dumbbell mounting bracket.
　態様の一例のバーベル用ダンベル取付け金具は、バーベルシャフトの端部に取り付けるバーベルシャフト取付部と、バーベルシャフトに対して直交する形態でダンベルのシャフトを固定するダンベルシャフト取付部と、を備える。 A dumbbell mounting bracket for a barbell according to one embodiment includes a barbell shaft mounting portion that is mounted on the end of the barbell shaft, and a dumbbell shaft mounting portion that fixes the shaft of the dumbbell in a manner orthogonal to the barbell shaft.
　本発明によれば、一般的なダンベルを連結することができるバーベル用ダンベル取付け金具、及びダンベル取付け金具を具備するバーベルシャフトを提供することが可能となる。 According to the present invention, it is possible to provide a dumbbell mounting bracket for a barbell to which general dumbbells can be connected, and a barbell shaft equipped with the dumbbell mounting bracket.

　具体的には、バーベル用ダンベル取付け金具１００は、バーベルシャフト取付部１０２の上側部分１０２ａとダンベルシャフト取付部１０１の上側部分１０１ａとが一体に成形された上側部品１０２ａ＋１０１ａを備える。また、バーベル用ダンベル取付け金具１００は、バーベルシャフト取付部１０２の下側部分１０２ｂとダンベルシャフト取付部１０１の下側部分１０１ｂとが一体に成形された下側部品１０２ｂ＋１０１ｂを備える。バーベル用ダンベル取付け金具１００は、バーベルシャフト１１０取付時、バーベルシャフト取付部１０２を形成する上側部分１０２ａと下側部分１０２ｂとは、円柱空洞部２０３を形成している。また、バーベルシャフト１１０取付時、ダンベルシャフト取付部１０１を形成する上側部分１０１ａと下側部分１０１ｂとは、一方の端部は開いて円柱空洞部２０３の端部を構成し、他方の端部は閉じて蟻継ぎ手を形成している。 Specifically, the dumbbell mounting bracket 100 for barbells includes an upper part 102a+101a in which the upper part 102a of the barbell shaft mounting part 102 and the upper part 101a of the dumbbell shaft mounting part 101 are integrally formed. The barbell dumbbell mounting bracket 100 also includes a lower part 102b+101b in which the lower portion 102b of the barbell shaft mounting portion 102 and the lower portion 101b of the dumbbell shaft mounting portion 101 are integrally formed. When the barbell shaft 110 is attached to the dumbbell mounting bracket 100 for a barbell, the upper portion 102 a and the lower portion 102 b forming the barbell shaft mounting portion 102 form a cylindrical hollow portion 203 . When the barbell shaft 110 is attached, the upper portion 101a and the lower portion 101b forming the dumbbell shaft attachment portion 101 are open at one end to constitute the end of the cylindrical hollow portion 203, and the other end is open. It closes to form a dovetail joint.
　第１の実施形態において、ユーザは、バーベルシャフト１１０にダンベル１２０を取り付ける場合には、上側部品１０２ａ＋１０１ａと下側部品１０２ｂ＋１０１ｂとによってバーベルシャフト１１０及びダンベルシャフト１２１を挟み込む。その後、ユーザは、上側部品１０２ａ＋１０１ａと下側部品１０２ｂ＋１０１ｂにそれぞれ空けられたネジ貫通穴１０３に例えば六角穴付きのボルトネジ１０４を通す。そして、ユーザは、図２Ｂに示すように、ボルトネジ１０４の一端にナット２０１をねじ込んでから、例えば六角レンチを用いて締め付けることにより、バーベルシャフト１１０とダンベルシャフト１２１を固定する。
　このため、バーベルシャフト１１０は、ボルトネジ１０４を貫通させるための不図示のネジ貫通穴を有する。これにより、バーベルシャフト１１０とダンベルシャフト１２１とを、バーベル用ダンベル取付け金具１００に同時かつ確実に取り付けることができる。 In the first embodiment, when attaching the dumbbell 120 to the barbell shaft 110, the user sandwiches the barbell shaft 110 and the dumbbell shaft 121 between the upper part 102a+101a and the lower part 102b+101b. After that, the user inserts, for example, a bolt screw 104 with a hexagonal hole into the through hole 103 provided in each of the upper part 102a+101a and the lower part 102b+101b. Then, as shown in FIG. 2B, the user fixes the barbell shaft 110 and the dumbbell shaft 121 by screwing the nut 201 into one end of the bolt screw 104 and tightening it with, for example, a hexagonal wrench.
For this reason, the barbell shaft 110 has a screw through hole (not shown) through which the bolt screw 104 is passed. Thereby, the barbell shaft 110 and the dumbbell shaft 121 can be simultaneously and reliably attached to the dumbbell mounting bracket 100 for barbells.
　図２Ｄにおいて、バーベルシャフト取付部１０２を形成する上側部分１０２ａと下側部分１０２ｂとで形成される円柱空洞部２０３に差し込まれるバーベルシャフト１１０の太さは、例えばレギュラーシャフトの２８ミリメートル（以下「ｍｍ」と記載）であってよい。これより太い、例えば５０ｍｍ用のバーベル用ダンベル取付け金具１００が用意されてもよい。 In FIG. 2D, the thickness of the barbell shaft 110 inserted into the cylindrical hollow portion 203 formed by the upper portion 102a and the lower portion 102b forming the barbell shaft attachment portion 102 is, for example, 28 millimeters (hereinafter "mm ”). A dumbbell mounting bracket 100 for barbells thicker than this, for example, 50 mm, may be prepared.
　図２Ｂにおいて、ダンベルシャフト取付部１０１を形成する上側部分１０１ａと下側部分１０１ｂとで形成される円柱空洞部２０２内に挟まれるダンベル１２０のシャフト１２１の太さも、例えば２８ｍｍであってよい。ダンベルシャフト取付部１０１によるダンベルシャフト１２１の保持は、挟み込みの形式のため、２８ｍｍを中心として前後１０ｍｍ程度の太さの変化にまで適合できる。更に、一般的なダンベルシャフト１２１の太さのバリエーションを考慮して、異なる太さに適合するバーベル用ダンベル取付け金具１００が用意されてもよい。 In FIG. 2B, the thickness of the shaft 121 of the dumbbell 120 sandwiched in the cylindrical hollow portion 202 formed by the upper portion 101a and the lower portion 101b forming the dumbbell shaft attachment portion 101 may also be 28 mm, for example. Since the dumbbell shaft 121 is held by the dumbbell shaft attachment portion 101 in a pinching manner, it can adapt to changes in thickness of about 10 mm forward and backward from 28 mm. Furthermore, in consideration of variations in the thickness of common dumbbell shafts 121, dumbbell mounting brackets 100 for barbells adapted to different thicknesses may be prepared.
　第１の実施形態におけるバーベル用ダンベル取付け金具１００は、２個セットで単品として販売することができるが、バーベルシャフト１１０とセットで販売することもできる。 The dumbbell mounting bracket 100 for barbells in the first embodiment can be sold as a set of two as a single item, but can also be sold as a set with the barbell shaft 110 .
