Description
【考案の詳細な説明】 この考案はパンタグラフ型ジヤツキに関する。[Detailed explanation of the idea] This invention relates to a pantograph type jack.
この種パンタグラフ型手動ジヤツキは、自動車
毎に１台携行され、パンク修理その他でタイヤ交
換を行う際に用いられるものである。そこで、大
量に生産されるものであり、軽微な合理化にあつ
てもその経済効果は莫大なものがあり、したがつ
て、特に低コストが要請されるものである。 This type of pantograph-type manual jack is carried by each vehicle, and is used when changing tires for puncture repairs or other purposes. Therefore, since they are produced in large quantities, even slight rationalization can have a huge economic effect, and therefore low cost is particularly required.
また常時自動車に携行する点と、使用便宜から
軽量化が求められるものである。 Furthermore, it is required to be lightweight because it is always carried in a car and for convenience of use.
この考案は、前記の点に鑑みてなされたもので
あつて、特にこの種ジヤツキの主要部であるアー
ムを改良し、前記目的を達成するものである。 This invention was made in view of the above-mentioned points, and in particular improves the arm, which is the main part of this type of jack, to achieve the above-mentioned object.
以下、この考案を図面に示す実施例により説明
すると、１はパンタグラフ型ジヤツキであつて、
２はベース、３，４は下アーム、５，６は上アー

ル、１１はネジ棒、１２はハンドル接手である。 This invention will be explained below with reference to the embodiments shown in the drawings. 1 is a pantograph type jack;
2 is a base, 3 and 4 are lower arms, 5 and 6 are upper arms, 7 is a receiving frame, 8 is a receiving plate, 9 and 10 are metals, 11 is a threaded rod, and 12 is a handle joint.
次に、上記下アーム３，４および上アーム５，
６の構成を、下アーム４を、その製造工程を通し
て説明する。アーム用平鋼板素材１３は、第２図
および第３図に示すように両側縁の所要巾を厚肉
t1に、その中間を薄肉t2に形成している。 Next, the lower arms 3, 4 and the upper arm 5,
6 and the lower arm 4 will be explained through its manufacturing process. As shown in FIGS. 2 and 3, the flat steel plate material 13 for the arm is thickened to the required width of both side edges.
t 1 , and a thin wall t 2 is formed in the middle.
前記素材１３を第２図において２点鎖線にて示
すような展開形状に型抜きし、次に両側部を型押
成形によりコ字形に起立させ、第５図および第６
図に示すごとく、ギヤー部４ａおよびメタル接続
部４ｂを厚肉t1に、中間身部４ｃを薄肉t2に形成
し、もつて、下アーム４を設けるものである。 The raw material 13 is die-cut into a developed shape as shown by the two-dot chain line in FIG.
As shown in the figure, the gear part 4a and the metal connecting part 4b are formed to have a thick wall t1 , and the intermediate body part 4c is formed to have a thin wall t2 , and then the lower arm 4 is provided.
尚、アーム用平鋼板素材１３の横断面は第４図
のようになつてもよいものである。 Incidentally, the cross section of the flat steel plate material 13 for the arm may be as shown in FIG. 4.
この考案は、以上のように上下のアーム３，
４，５，６を前記のように設けるものであるか
ら、各ギヤー部は互に噛合するために十分な歯巾
をもち、またメタル接続部はメタルにカシメ着を
するに必要な厚みと強度をもち、中間の身部につ
いては薄肉に構成されるが、上下、左右の四要素
から構成されるため、座屈強度では要求される強
度を十分に具えるものである。 This idea is based on the upper and lower arms 3,
4, 5, and 6 are provided as described above, each gear part has sufficient tooth width to mesh with each other, and the metal connection part has the thickness and strength necessary for caulking to the metal. Although the middle body part is thin, it has sufficient buckling strength as it is made up of four elements: top, bottom, left and right.
従来、アームに薄鋼板を用いた場合は一方のギ
ヤー部には補強枠を内側に添設し、他方のメタル
接続部には特別な接続加工を施工しなければなら
ず、したがつて、コスト的には期待するほど低減
されなかつた。この考案によると、アーム用平鋼
板素材は、特殊形状に圧延されるが、一環大量製
造が行えるのでコストアツプにならず、ジヤツキ
のアームへの加工は従来の平板同様に行え、アー
ムの約2/3をしめる中間身部の軽量化と、材量節
約によるコストの低減に効果がある。 Conventionally, when thin steel plates were used for the arm, a reinforcing frame had to be attached inside one gear part, and a special connection process had to be performed on the other metal connection part, which resulted in lower costs. However, it was not reduced as much as expected. According to this invention, the flat steel plate material for the arm is rolled into a special shape, but since it can be mass-produced as a part, the cost does not increase, and the processing into the jack arm can be done in the same way as a conventional flat plate, and about 2/2 of the arm It is effective in reducing the weight of the mid-body part that closes the part 3 and reducing costs by saving material.
