Abstract
Description
本発明は、自動車の車軸に設けられたタイヤ取付け部のボルトと、タイヤホイールのボルト穴の位置を合わせ、タイヤ取り付け部にタイヤを取り付けるタイヤ交換ジャッキに関するものである。 The present invention relates to a tire replacement jack in which a bolt of a tire mounting portion provided on an axle of an automobile and a bolt hole of a tire wheel are aligned to attach a tire to the tire mounting portion.
家庭で自動車のタイヤを交換するときは、ホイールからナットをはずした後タイヤを手で持って取り外していた。取り外すときは特に補助道具を用いなくてもそれほどの苦労もなく出来るが、取り付けには重いタイヤを手で持って作業をするため、相当な労力を要した。これを手で持たずに出来る補助道具は無いかと、量販店等を探したが家庭用としての製品は無かった。勿論、今までに市中に出回っているのを見かけたこともない。 When changing car tires at home, the nuts were removed from the wheels and the tires were removed by hand. When removing it, it can be done without much effort even without using auxiliary tools, but it took a lot of effort to carry it out with heavy tires in hand. I looked for a mass retailer to find out if there was an auxiliary tool that I could do without holding it by hand, but there was no product for household use. Of course, I have never seen it in the city.
そのために、次のような問題点があった。
(イ)特に積雪地では、普通タイヤと冬用タイヤは季節に応じて年2回交換しなければならない。そのためタイヤの交換には、相当な労力または費用を要した。
(ロ)タイヤを取り外すときはともかく、取り付けるときは重いタイヤを手で持ち上げ、タイヤ取付け部のボルトにホイールのボルト穴を合わせて嵌め込まなければならない。一度で合致すればまだ良いが、なかなか合致しないときなどは重いタイヤを長い間持ち、しかも中腰で作業しているため腰への負担が大きく腰を痛める人も多い。特に力の弱い高齢者や女性には、仮に出来ても大変な重労働であり作業時間も長時間を要す。
(ハ)RV車、キャンピングカーなど更に重いタイヤでは、若い男性でも一人で作業を行うことは困難である。
本発明は、これらの問題点を解決するためになされたものである。Therefore, there are the following problems.
(B) Especially in snowy areas, normal tires and winter tires must be changed twice a year depending on the season. Therefore, considerable effort or cost was required for tire replacement.
(B) Regardless of when removing the tire, when attaching it, the heavy tire must be lifted by hand and fitted with the wheel bolt holes aligned with the bolts on the tire mounting part. Although it is still good to match at once, there are many people who have heavy tires for a long time when they do not match well and work on the middle waist, which places a heavy burden on the waist and hurts the waist. In particular, elderly people and women who are weak have a lot of hard work and long working hours.
(C) With heavier tires such as RV cars and campers, it is difficult for even a young man to work alone.
The present invention has been made to solve these problems.
ローラ支持板の両端にローラを取り付け、中心にはローラに平行にスケール収納溝を設ける。その奥に蝶番等で固定し立てたり倒したりでき、また伸縮も可能なスケールを取り付ける。
更に、パンタグラフ型ジャッキのリンクを左右に分離したかたちで、それぞれをローラ支持板の底面と台座に固定し取り付けたことを特徴とするタイヤ交換ジャッキ。A roller is attached to both ends of the roller support plate, and a scale storage groove is provided in the center in parallel with the roller. At the back of the scale, attach a scale that can be fixed with a hinge, etc.
Furthermore, the tire replacement jack is characterized in that the links of the pantograph type jack are separated into left and right, and each is fixed and attached to the bottom surface of the roller support plate and the base.
本発明を使用することにより、高齢者や女性など力の弱い人でも、腰を痛めることなく家庭で容易に、しかも短時間でタイヤ交換が可能となる。
また、RV車やキャンピングカーなどの重いタイヤでも年齢性別を問わず交換が可能である。更に本発明は、構造が簡単で小型なため消費者に安価で提供できる。By using the present invention, even a weak person such as an elderly person or a woman can easily change tires at home without hurting the waist.
Even heavy tires such as RV cars and campers can be replaced regardless of age and gender. Furthermore, the present invention can be provided to consumers at low cost because of its simple structure and small size.
以下、本発明の実施の形態について説明する。
(イ)ローラ支持板(1)の両端にローラ(2)を取り付ける。支持板(1)の中央にはローラ(2)に平行にスケール収納溝(3)を設け、その奥に立てたり倒したり出来るスケールa(4)を蝶番等で取り付ける。スケールa(4)は中空とし、その中にスケールb(5)を伸縮可能な状態で収納する。
(ロ)ローラ支持板(1)の底面と台座(9)の上にパンタグラフ型ジャッキのリンク(6)を左右に分離したかたちでそれぞれ取り付ける。これはジャッキを最低位置まで下ろしたとき、ねじの頭(8)が支持板(1)の下にならないためと、使用中の安定性を確保するためである。
(ハ)左右のリンク(6)は一本のねじ(7)で連結され、ねじの頭(8)はナット型とする。
(ニ)使用中に本発明が滑って移動しないように、台座(9)の底面周囲に、板ゴム等で滑り止め(10)を付ける。
本発明は以上のような構成で、タイヤを取り付けるときは「図3」のように本発明のスケールaの基部(4’)がタイヤ取付け部(11)の中心点の直下になるように置き、スケールbの頭(5’)を指でつまみ、スケールa(4)を垂直に立てる。
ここでスケールbの頭(5’)とタイヤ取付け部(11)の中心点が一致していなければ本発明の位置を移動して一致したところに設置する。スケールbの頭(5’)がタイヤ取付け部(11)の中心点より低いときは必要に応じてスケールbの頭(5’)を引き上げて、中空のスケールa(4)に収容されているスケールb(5)を伸ばす。本発明の設置位置が確定したら逆の手順でスケールa(4)を収納溝(3)に収める。
次に、「図4」のようにローラ(2)の上にタイヤ(13)を片手で押さえながら立てて乗せ、ねじの頭(8)をスパナ又はトルクレンチ等で回しながら上下させ、タイヤ取付け部のボルト(12)「図3」とホイールのボルト穴(15)の高さを合わせる。
あとは両手でタイヤ(13)を右又は左に若干回転させ、ボルト(12)とボルト穴(15)が合致するように微調整する。このときローラ(2)も同時に回転するので位置合わせは容易に出来る。
最後にタイヤの下部を手で押してローラ(2)の上を滑らせホイールのボルト穴(15)をボルト(12)に嵌め込み、ナットで固定して取付けを完了する。
なお、ジャッキはタイヤを上下させるためのもので、それに耐える力があればよく、ストローク(ジャッキの上げ幅)も車両のジャッキアップの高さにもよるが、通常であれば10cm前後あれば十分なので極めて小型なもので足りる。Hereinafter, embodiments of the present invention will be described.
(A) The roller (2) is attached to both ends of the roller support plate (1). A scale housing groove (3) is provided in the center of the support plate (1) in parallel with the roller (2), and a scale a (4) that can be stood or tilted is attached by a hinge or the like. The scale a (4) is hollow, and the scale b (5) is accommodated in the state in which the scale b (5) can be expanded and contracted.
(B) Attach the link (6) of the pantograph jack on the bottom surface of the roller support plate (1) and the pedestal (9) in a manner separated into left and right. This is because when the jack is lowered to the lowest position, the screw head (8) does not fall under the support plate (1), and stability during use is ensured.
(C) The left and right links (6) are connected by a single screw (7), and the screw head (8) is a nut type.
(D) A slip stopper (10) is attached around the bottom surface of the pedestal (9) with a rubber plate or the like so that the present invention does not slip and move during use.
The present invention is configured as described above, and when the tire is mounted, the base (4 ′) of the scale a of the present invention is placed immediately below the center point of the tire mounting portion (11) as shown in FIG. Then, the head (5 ') of the scale b is pinched with a finger, and the scale a (4) is set up vertically.
Here, if the head (5 ') of the scale b and the center point of the tire mounting portion (11) do not coincide, the position of the present invention is moved and installed at the coincident place. When the head (5 ′) of the scale b is lower than the center point of the tire mounting portion (11), the head (5 ′) of the scale b is pulled up as necessary, and is accommodated in the hollow scale a (4). Increase scale b (5). When the installation position of the present invention is determined, the scale a (4) is stored in the storage groove (3) in the reverse procedure.
Next, as shown in FIG. 4, the tire (13) is placed on the roller (2) while being held down with one hand, and the screw head (8) is moved up and down with a spanner or torque wrench to attach the tire. Align the height of the bolts (12) in Fig. 3 with "Fig. 3" and the bolt holes (15) in the wheel.
After that, the tire (13) is slightly rotated to the right or left with both hands and finely adjusted so that the bolt (12) and the bolt hole (15) are aligned. At this time, the roller (2) also rotates at the same time, so that the alignment can be easily performed.
Finally, the lower part of the tire is pushed by hand to slide on the roller (2), and the bolt hole (15) of the wheel is fitted into the bolt (12) and fixed with a nut to complete the installation.
The jack is used to raise and lower the tire, and it only needs to be able to withstand it. The stroke (raising width of the jack) also depends on the height of the jack-up of the vehicle, but usually around 10 cm is sufficient. A very small one is enough.
