Description

本発明は、自動車等のタイヤ交換作業を補助するタイヤ脱着補助具に係る。   The present invention relates to a tire attachment / detachment aid that assists in tire replacement work of an automobile or the like.

自動車のタイヤ交換を行う場合は、ボルトを外した後にタイヤを中腰の姿勢にて両手で取り外し、この中腰の姿勢からタイヤを持ち上げ、またタイヤを取り付けるときにも中腰で車軸のスタッドにホイールの穴を合わせる作業を行う必要がある。
従って、タイヤ交換作業により腰を痛めるケースも多い。
このタイヤ脱着作業は、雪国では冬用タイヤとノーマルタイヤとの交換を毎年定期的に行う必要があり、また、パンク等が発生することでも行う必要がある。
タイヤ交換補助器具として、実開平７−３３７０６号公報には、左右に分割した本体をボルト棒とナットで連結し、ボルト棒を手回しノブで回転させることで左右の本体の間隔を変え、左右の本体のローラー上にまたがらせるように載せたタイヤをローラー間隔を狭くすることで上昇させる技術を開示する。
しかしながら、この構造では取り付けるタイヤの高さを調整するためには、ボルトを回転させてローラー間隔を広狭することになるので、ボルトの一回転あたりのタイヤの上下移動量が非常に少なく却って作業が面倒なものとなる恐れがあった。 When changing the tire of a car, remove the bolt with both hands after removing the bolt, lift the tire from this middle waist position, and also when attaching the tire, the wheel hole in the axle stud at the middle waist It is necessary to work to match.
Therefore, there are many cases where the tiredness is injured by the tire replacement work.
In the snowy country, it is necessary to replace the tire for winter and the normal tire regularly every year, and it is also necessary to perform this tire demounting work due to occurrence of puncture or the like.
As a tire replacement aid, Japanese Utility Model Laid-Open No. 7-33706 discloses that the main body divided into left and right is connected with a bolt rod and a nut, and the bolt rod is manually rotated and rotated with a knob to change the interval between the left and right main bodies. Disclosed is a technique for raising a tire placed so as to straddle a roller of a main body by narrowing a roller interval.
However, in this structure, in order to adjust the height of the tire to be installed, the bolts are rotated to widen the gap between the rollers. Therefore, the amount of vertical movement of the tire per one rotation of the bolt is very small, and the work is not performed. There was a risk of troublesomeness.

実開平７−３３７０６号公報Japanese Utility Model Publication No. 7-33706

本発明は上記技術的課題に鑑みて、タイヤの上下位置の調整を手早く行えるタイヤ脱着補助具を提供することを目的とする。   In view of the above technical problem, an object of the present invention is to provide a tire attachment / detachment aid that can quickly adjust the vertical position of a tire.

図４（ロ）、図３（ロ）の状態のように一方の手５ｂでハンドル１３を握り、もう一方の手５ａでタイヤ３ｃの上部を支え、ハンドル１３を回し、カム１４を回転させてタイヤ支持ローラー部材１２ａ、１２ｂを持ち上げ、タイヤ３ｃを持ち上げる。
この時ラチェット機構部によりカム１４位置を固定すると両手作業を行える。
このようにタイヤ３ｃを持ち上げた上で、車軸２のスタッド２ａからタイヤ３ｃのホイールの穴を外すために矢印Ａ方向に引き出す。
引き出した後に、ラチェット機構部のラッチを解除しハンドル１３を戻してタイヤ支持ローラー部１２ａ、１２ｂを下降させ図４（ハ）、図３（ハ）のようにタイヤ３ｃを下げる。
そして、図３（ハ）の矢印Ｃ方向にタイヤ３ｃをスロープ１８を利用してタイヤ脱着補助具１０より転がして取り出す。
このように、タイヤの取り外しを、カム機構を利用して行うために手早く楽に取り外し作業が出来る。 A method for raising and lowering a tire using the tire attachment / detachment aid will be described with reference to FIGS. 3 and 4.
FIG. 3 is a main part view in which the handle, cover and the like on the front side of the tire attachment / detachment aid are omitted for the sake of clarity.
When the tire is taken down, the vehicle body is lifted with a jack (not shown) or the like, and the tire 5 is removed from the tire with the nut removed, as shown in FIGS. 4 (a) and 3 (a). The roller members 12a and 12b are inserted so as to be positioned below the tire tread surface 3e.
As shown in FIGS. 4B and 3B, the handle 13 is held by one hand 5b, the upper part of the tire 3c is supported by the other hand 5a, the handle 13 is turned, and the cam 14 is rotated. The tire support roller members 12a and 12b are lifted, and the tire 3c is lifted.
At this time, if the position of the cam 14 is fixed by the ratchet mechanism, two-hand operation can be performed.
After lifting the tire 3c in this way, the tire 3c is pulled out in the direction of arrow A in order to remove the wheel hole of the tire 3c from the stud 2a of the axle 2.
After being pulled out, the latch of the ratchet mechanism is released, the handle 13 is returned, the tire support roller portions 12a and 12b are lowered, and the tire 3c is lowered as shown in FIGS. 4 (c) and 3 (c).
Then, the tire 3c is rolled out from the tire attachment / detachment aid 10 using the slope 18 in the direction of arrow C in FIG.
As described above, since the tire is removed using the cam mechanism, the removal work can be performed quickly and easily.

一方タイヤ３ｃの取り付けは概ね逆の手順となる。
先ず図３（ニ）の矢印Ｄ方向にタイヤ３ｄを転がし、スロープ１８を利用してタイヤ３ｄをタイヤ脱着補助具１０のタイヤ支持ローラー部材１２ａ、１２ｂ上に載せ、図３（ハ）、図４（ハ）に示す状態とする。
