Description

本発明は、ショベルに関するものである。   The present invention relates to shovels.

従来から、例えば土や雪などの被掘削物を掘削するためのショベルとして実用新案登録第３００５６１１号に開示されるようなショベル（以下、従来例）が提案されている。   BACKGROUND ART Conventionally, as a shovel for excavating an object to be excavated, such as soil and snow, a shovel (hereinafter referred to as a conventional example) disclosed in Utility Model Registration No. 3005611 has been proposed.

この従来例は、図13に図示したように柄部51の先端部に掬い部52、基端部に握持部55が設けられ、更に、柄部51の先端側には先端側握持部53が固着された構造であり、この先端側握持部53は、柄部51に設けられる支承部材53ａと、この支承部材53ａの先端部に架設されたグリップ部材53ｂとを有するものである。   In this conventional example, as shown in FIG. 13, a scooping part 52 is provided at the tip end of a handle 51, and a gripping part 55 is provided at the base end, and the tip side gripping part is provided at the tip side of the handle 51. 53 has a fixed structure, and the tip-side grip portion 53 has a support member 53a provided on the handle 51 and a grip member 53b installed on the tip of the support member 53a.

従って、被掘削物Ｓに掬い部52を刺し込んだ状態から掬い上げる際、片方の手で先端側握持部53のグリップ部材53ｂを握持し、もう片方の手で握持部55を握持し、この状態でグリップ部材53ｂを支点に握持部55を下方に押し込むことで、梃子の原理を利用して被掘削物Ｓに刺し込んだ掬い部52を上げることができ、よって、柄部51の先端側を握持した状態で掬い上げる場合に比して被掘削物Ｓを楽に掬い上げることができる。   Therefore, when scooping up the scooping part 52 from the excavated object S, the gripping member 53b of the tip-side gripping part 53 is grasped by one hand and the gripping part 55 is grasped by the other hand. By holding and holding the grip member 53b as a fulcrum and pushing the gripping portion 55 downward, the scooping portion 52 pierced into the excavation object S can be raised by utilizing the principle of leverage, and thus the handle The object S to be excavated can be easily picked up as compared with the case where the tip end side of the portion 51 is held and gripped.

実用新案登録第３００５６１１号公報Utility Model Registration No. 3005611

ところで、掬い部52で被掘削物Ｓを掬い上げた後に搬送する際など、左右の手を伸ばして同じ高さの位置で持つ姿勢が楽であるが、従来例は、その構造上、左右の手を伸ばして同じ高さ位置にして楽な姿勢をとろうとすると、掬い部52が傾斜状態となり掬った被掘削物Ｓがこぼれ易い状態になる（図13の状態）。よって、掬い部52を水平状態とすべく先端側握持部53を握持する側の手を余分に上方へ位置させなければならず（先端側握持部53を握持する側の手を多少縮めなければならないから）、非常に大変である。   By the way, when the object S to be excavated by the scooping section 52 is picked up and conveyed, it is easy to hold the left and right hands and hold them at the same height position. When the user reaches out to the same height position and tries to take a comfortable posture, the scooping part 52 is inclined and the scooped object S is spilled easily (state of FIG. 13). Therefore, in order to make the scooping part 52 horizontal, the hand on the side holding the tip-side grip 53 must be located above the hand (the hand on the side gripping the tip-side grip 53). It must be shortened a little), so it is very difficult.

The height (distance) from the handle 1 to the grip member 4b of the gripping part 4 can be made substantially the same, and when carrying work in this state, the scooping part 2 is in a horizontal state, so that the scooping part 2 The excavated object S can be transported in a comfortable posture without spilling.

また、本実施例は、基端側握持部４は、支承部材４ａを柄部１の先端方向へ倒伏させた折り畳み状態と、柄部１の基端方向へ倒伏させた展開状態とに切り替え可能に設けられており、例えば基端側握持部４を折り畳んだコンパクトな状態にすることができる。   Further, in this embodiment, the base-side grip portion 4 is switched between a folded state in which the support member 4a is laid down in the distal direction of the handle 1 and a deployed state in which the support member 4a is laid down in the proximal direction of the handle 1. It is provided so that, for example, the proximal-side grip portion 4 can be folded into a compact state.

また、本実施例は、支承部材４ａを柄部１の基端方向へ倒伏させた展開状態とした際、グリップ部材４ｂが柄部１の基端よりも外側に位置するように設けられているから、基端側握持部４を通常のショベルの握柄部と同様の機能を発揮させることができる。   In the present embodiment, the grip member 4b is provided so as to be located outside the base end of the handle portion 1 when the support member 4a is laid down in the base end direction of the handle portion 1 in a deployed state. Therefore, the proximal-side grip portion 4 can exhibit the same function as that of the grip handle portion of a normal shovel.

また、本実施例は、掬い部２は、柄部１の先端部に回動自在に設けられ、掬い部２には柄部１に対し該掬い部２を所定の角度で保持する掬い部角度保持機構７が設けられているから、掬い部２を使用者の使用し易い最適な状態が得られることになる。   Further, in this embodiment, the scooping part 2 is rotatably provided at the tip of the handle part 1, and the scooping part 2 holds the scooping part 2 at a predetermined angle with respect to the handle part 1. Since the holding mechanism 7 is provided, the scooping portion 2 can be in an optimal state in which the user can easily use it.

また、本実施例は、柄部１の基端にはハンマーなどの殴打作業部材８，ツルハシなどの破砕作業部材が着脱自在に設けられているから、多機能で非常に使い勝手の良いものとなる。   Further, in the present embodiment, since the striking work member 8 such as a hammer and the crushing work member such as a pickaxe are detachably provided at the base end of the handle portion 1, it is multi-functional and extremely convenient. .
