Description
【０００１】[0001]
本考案は自転車用固定装置に関する。 The present invention relates to a bicycle fixing device.
【０００２】[0002]
従来の自転車用固定装置としては図１に示されるように一般的なボルトおよび ナット、図２に示されるようにボルト頭部またはナット頭部に締め付け用ロッド 棒を備えたもの、図３に示されるようにクイックレリーズ方式のものがあり、こ れらは使用個所、使用目的により使い分けられている。 A conventional bicycle fixing device includes a general bolt and nut as shown in FIG. 1, a bolt or nut head having a tightening rod as shown in FIG. 2, and FIG. There are also quick release systems, which are used depending on the place of use and the purpose of use.
【０００３】 例えば、競技用自転車の車輪の固定装置は迅速に車輪交換できるよう、また本 格的なマウンテンバイクのシートピラー固定装置は走行路状況に応じたサドル高 さに迅速に調整できるよう、図３のようなクイックレリーズ方式の固定装置が採 用され、比較的調整頻度の高い一般軽快車のシートピラー固定装置には工具無し で軽く操作できるよう、図２のような締め付け用ロッド棒を備えた形式のものが 採用されているように、クイックレリーズ方式のものは迅速な作業に適している が使用方法を誤ると十分な固定力が得られないため熟練者用、ロッド棒形式を含 むボルトおよびナット形式は作業にやや時間がかかるが使用方法が分かりやすい ため一般用として使い分けされているのである。[0003] For example, the fixing device of the wheel of the racing bicycle can be changed quickly, and the seat pillar fixing device of the genuine mountain bike can be quickly adjusted to the saddle height according to the road conditions. A quick release type fixing device as shown in Fig. 3 is adopted. The seat pillar fixing device of a general light vehicle, which is relatively frequently adjusted, is equipped with a tightening rod as shown in Fig. 2 so that it can be operated lightly without tools. The quick release type is suitable for quick work, as in the case of a type equipped with a rod. Bolts and nuts take a little time to work, but they are used for general purposes because they are easy to understand.
【０００４】[0004]
しかしながら一般用に採用されているロッド棒形式のものは、固定するために は、ボルトまたはナットを数回転しなければならず、その際、ロッド棒がフレー ムなどに接触しスムーズな締め付けを困難にしているだけでなく、かなりの力で 締め付けないと完全に固定されないという問題点がある。 However, the rod rod type that is generally used requires several turns of the bolt or nut to fix it, and at that time, the rod rod comes into contact with the frame etc., making it difficult to tighten it smoothly. In addition to this, there is a problem that it cannot be completely fixed unless it is tightened with considerable force.
【０００５】 また逆に緩める場合も固定時と同様かなりの力を必要とし、さらに１回転以上 緩めないとシートポストを調整できないのであり、女性や子供にとっては非常に 困難な作業となるのである。On the other hand, when the seat post is loosened, a considerable force is required as in the case of fixing. Further, if the seat post is not loosened more than one turn, the seat post cannot be adjusted, which is a very difficult task for women and children.
【０００６】 本考案はこのような状況に着眼し、少ない回転でまた軽い操作力で固定でき、 緩める場合も少ない回転でまた軽い操作力で緩めることのできる自転車用固定装 置を提供することにより調整の容易化や着脱の容易化を図るものである。The present invention has been made in view of such a situation, and by providing a bicycle fixing device that can be fixed with a small amount of rotation and with a small operating force and that can be loosened with a small amount of rotation and with a small amount of operating force. This facilitates adjustment and detachment.
【０００７】[0007]
本考案では固定ボルト先端部に右ネジであるオネジを備え、このオネジに螺合 する固定ナットを備えた自転車用固定装置において、固定ボルト基端部に概オネ ジとは逆の左ネジを設けこの左ネジに螺合する制御ナットを備えるか、あるいは 固定ナット基端部外周に概オネジとは逆の左ネジを設け、この左ネジに螺合する 制御ナットを備えることにより上記問題を解決している。 In the present invention, in the bicycle fixing device equipped with a male screw which is a right-hand screw at the tip of the fixing bolt and a fixing nut to be screwed to this male screw, a left-hand screw opposite to the general screw is provided at the base end of the fixing bolt. The above-mentioned problem is solved by providing a control nut to be screwed to the left screw, or providing a left screw opposite to the male screw on the outer periphery of the fixed nut base end and providing a control nut to be screwed to the left screw. ing.
【０００８】[0008]
本考案の第１の実施例は図４に示すように右ネジであるオネジを備えた固定ボ ルト１の頭部１ａには締め付け用ロッド棒３が設けられ、先端部には概オネジに 螺合する固定ナット２が備えられ、固定ボルト１の頭部基端部外周１ｂには概オ ネジより大径でかつ同じピッチの左ネジを設け、この左ネジに螺合し長さの若干 長い制御ナット４が備えられている。 In the first embodiment of the present invention, as shown in FIG. 4, a fastening rod 3 is provided on a head 1a of a fixed bolt 1 having a male screw as a right-hand screw, and a substantially male screw is provided at the tip. A fixing nut 2 is provided on the outer periphery 1b of the base end portion of the head of the fixing bolt 1. A left screw having a diameter larger than that of the male screw and having the same pitch is provided, and is screwed to the left screw to have a slightly longer length. A control nut 4 is provided.
【０００９】 本考案品でシートピラー５を固定する場合は図６のように制御ナットを組み込 んだ固定ボルト１をシートラグ６に挿入し回り止めプレート７を介して固定ナッ ト２をセットする。When fixing the seat pillar 5 with the product of the present invention, as shown in FIG. 6, a fixing bolt 1 incorporating a control nut is inserted into a seat lug 6, and a fixing nut 2 is set via a rotation preventing plate 7. .
【００１０】 シートピラー５を固定するために従来品と同様、ロッド棒３を時計方向に回転 していくと固定ナット２は回り止めプレート７により回転不能となっているので 制御ナット４は固定ボルト１と共に回転進行して、制御ナット４の固定ボルト頭 部１ａとは反対側の面４ａがシートラグ６の面６ａと接して、制御ナット４の固 定ボルト頭部１ａとは反対側の面４ａとシートラグ６の制御ナット４側の面６ａ との摩擦抵抗のため制御ナット４の回転が止まる。When the rod 3 is rotated clockwise to fix the seat pillar 5 in the same manner as in the conventional product, the fixing nut 2 cannot be rotated by the rotation preventing plate 7. 1, the surface 4a of the control nut 4 opposite to the fixing bolt head 1a comes into contact with the surface 6a of the seat lug 6, and the surface 4a of the control nut 4 opposite to the fixing bolt head 1a. The rotation of the control nut 4 stops due to frictional resistance between the control lug 6 and the surface 6a of the seat lug 6 on the control nut 4 side.
【００１１】 さらにロッド棒３を回転すると、当該摩擦抵抗より制御ナット４と固定ボルト １とのネジ抵抗の方が小さくまた左ネジであるため、制御ナット４は回転不能の ままで固定ボルト頭部１ａと制御ナット４は離反されていく事になり、シートポ スト５を固定していく事になる。When the rod 3 is further rotated, the screw resistance between the control nut 4 and the fixing bolt 1 is smaller than the frictional resistance and the screw is a left-handed screw. 1a and the control nut 4 are separated from each other, and the seat post 5 is fixed.
【００１２】 すなわち固定ボルト１と固定ナット２による通常の締め付け力にさらに制御ナ ット４と固定ボルト頭部１ａが離反する力が加わる事になるため、通常のボルト とナットで締付けるものに比べ大きな力が働くと共に、固定ボルト１と固定ナッ ト２による通常のネジ推進量に制御ナット４と固定ボルト頭部１ａとの離反する 方向へのネジ推進量が加わる事になるため、通常のボルトとナットで締付けるも のに比べ２倍の推進量となる。That is, since a force for separating the control nut 4 and the fixing bolt head 1a is further applied to the normal tightening force of the fixing bolt 1 and the fixing nut 2, compared with a normal bolt and nut. Since a large force is applied and the amount of screw propulsion in the direction in which the control nut 4 and the fixing bolt head 1a are separated from each other is added to the normal amount of screw propulsion by the fixing bolt 1 and the fixing nut 2, the normal bolt The amount of propulsion is twice as much as that tightened with nuts and nuts.
【００１３】 図５は第２の実施例で右ネジであるメネジを備えた固定ナット８の頭部８ａに は締め付け用ロッド棒３が設けられ、当概メネジに螺合する固定ボルト９が備え られ、固定ナット８の頭部基端部外周８ｂには当概メネジより大径でかつ同じピ ッチの左ネジを設け、この左ネジに螺合し長さの若干長い制御ナット４が備えら れているもので、前述のものと同じ作用効果が得られるものである。FIG. 5 shows a second embodiment of the present invention, in which a fixing rod 8 is provided on a head 8a of a fixing nut 8 having a female screw which is a right-hand screw, and a fixing bolt 9 which is screwed into the female screw. The outer periphery 8b of the base end portion of the head of the fixing nut 8 is provided with a left screw having a diameter larger than that of the female screw and having the same pitch, and a control nut 4 having a slightly longer length screwed to the left screw. The same operation and effects as those described above can be obtained.
【００１４】 なお制御ナット４のシートラグ当接面４ａには図７に示すローレット面１０の ように、摩擦抵抗を増やすための処理を施すのが良い。The seat lug abutment surface 4a of the control nut 4 is preferably subjected to a process for increasing frictional resistance, like the knurl surface 10 shown in FIG.
【００１５】[0015]
本考案品を使用すると従来品に比べ大きな締め付け力が得られると共に、ネジ の推進量も２倍になるので軽い力でかつ少ない回転数で固定する事ができるので 、従来、女性や子供では十分な固定力が得られなかったシートピラーの締め付け も楽に作業できるし、締め付けのための回転数も従来品に比べ半分になるので、 ロッド棒がフレームに接触する頻度も減り迅速な作業が行えるのである。 By using the product of the present invention, a large tightening force can be obtained compared to the conventional product, and the amount of screw propulsion is doubled, so it can be fixed with a light force and with a small number of rotations. Fastening of the seat pillar, which did not provide a sufficient fixing force, can be performed easily, and the number of rotations for tightening is half that of the conventional product, so the frequency of rod rod contact with the frame is reduced and quick work can be performed. is there.
【００１６】 もちろん締付ける時だけでなく、ゆるめる時も同様の効果を発揮し、軽い力で 迅速に作業を行える。Of course, the same effect is exhibited not only when tightening but also when loosening, and the work can be performed quickly with a light force.
【００１７】 なお本考案はシートピラーの固定に限定されるものではなくハンドルステムの 固定にも利用でき、この場合ハンドルを約９０度回転させる事で車巾が狭くなる ため団地の玄関にも場所を取らずに保管できるし、輸送の場合、車巾が狭くなっ た分多くの台数を輸送できるので本考案品は非常に有効である。The present invention is not limited to fixing the seat pillar, but can also be used for fixing the steering wheel stem. In this case, turning the steering wheel by about 90 degrees narrows the vehicle width. The present invention is very effective because it can be transported without taking up a lot, and in the case of transportation, a large number of vehicles can be transported as the vehicle width is reduced.
【００１８】 そのほか締め付けおよび弛緩が必要な個所に使用する事ができるしまた、自転車 以外の他の分野にも応用できるのである。In addition, it can be used where tightening and relaxation are required, and can be applied to other fields besides bicycles.
