JP 2007-177599 A

Scoops are used for power work, and when scooping up dirt, sand, gravel, etc., the load must be able to withstand, so the angle can be changed between the handle part and the part ahead. As a structure for this, it is necessary to firmly fix the angle so that the angle after the change does not shift.
Such a structure that enables firm angle fixing tends to be costly because it is structurally robust and complicated, and also tends to increase in terms of load. Furthermore, the operability for changing the angle is not good because the number of actions increases.

For these reasons, it has been awaited to develop an angle-changing structure that can withstand practical use for scooping tools such as jolens and grooved wipers used in civil engineering, agriculture, kitchen gardening, and cleaning.
The present invention has been made in view of the above circumstances, and is a structurally simple and lightweight rake tool that can be used in various works such as civil engineering, agriculture, kitchen gardening, and cleaning. It is an object of the present invention to provide a scooping tool that can withstand practical use as it can be easily and quickly performed, and can be surely fixed in angle after operation.

That is, the scooping tool according to the present invention has a handle portion and a work implement portion provided at the tip of the handle portion, and the work implement portion includes a bottom plate provided with water-permeable holes and left and right ends of the bottom plate. It has a pair of side walls that rise and a rear wall that rises at the rear end of the bottom plate, and the handle portion and the work implement portion are flexibly connected in a direction in which the tip of the bottom plate swings up and down, and can be bent at this connecting portion. And an angle setting unit capable of switching between a fixed angle state at a plurality of fixed angles by a one-touch operation.
As described above, the angle setting unit can be used to switch between the handle portion and the work implement portion between a bendable state and an angle fixed state (fixed state at each of a plurality of fixed angles) by a one-touch operation. Thus, the use degree of the scooping tool has a high degree of freedom and is easy to use.

  In addition, the angle fixed state by the angle setting unit assumes that the bending angle between the handle portion and the work implement portion does not deviate unexpectedly during various operations. The switching operation by the angle setting unit is simple and quick that can be performed with one touch. The meaning of “one-touch” here is an operation that is troublesome and difficult (for example, an operation of tightening or loosening a screw, etc.) such as performing a plurality of operations in order, repeating, or requiring a strong operating force. ), But something that can be completed by a simple operation (for example, an operation of swinging a lever or pressing a button).

In the angle setting unit, a plurality of angles including an angle at which the handle portion and the upper surface of the bottom plate of the work implement portion are substantially orthogonal, and an acute angle (less than 90 °) and an obtuse angle (over 90 °) with respect to this angle are set. Good.
The angle setting unit has a bent support shaft provided with a shaft center substantially parallel to the upper surface of the bottom plate and the rear surface of the rear wall at the rear wall rear portion of the work implement portion, and supports the bent support shaft on the rear wall rear portion of the work implement portion.

It will be. In addition, the push operation unit can be easily operated (a state in which an operation force is easily applied).

The rear wall of the work implement part was formed with a notch that opened upward so that the handle could be stowed when bent until the upper surface of the bottom plate of the work implement and the handle were brought close to each other and made parallel. In contrast to this, the gear set member of the angle setting section enables the stopper piece to be locked when the upper surface of the bottom plate of the work implement section and the handle section are bent close to a parallel state. It is preferable that a locking groove is provided.
By doing in this way, the bottom plate top surface of the work implement part and the handle can be bent close to each other to be in a parallel state, so that the entire tool has a compact storage state in which the side overhang of the work implement part is folded.

Nine locking grooves 20 are provided at equal intervals in a range of 180 °. That is, the locking grooves 20 are arranged at 22.5 ° intervals.
The shaft support portion 17 is a portion in which a shaft hole 21 is formed so as to penetrate the tip of the handle portion 2, and the bending support shaft 15 is rotatably inserted into the shaft hole 21. The left and right gear cutting members 16 are arranged so as to sandwich the opening peripheral portions on both sides of the shaft hole 21 with respect to the shaft support portion 17. Therefore, when the cross-sectional shape of the handle 2 is circular, it is preferable to chamfer 22 on the outer peripheral surface of the handle 2 so that stable relative swinging with the gear cutting member 16 can be obtained. (See FIG. 6 and FIG. 8).

The operation lever 18 is provided so as to be swingable about a swing shaft 26 as a fulcrum with respect to a lever holding portion (bracket) 25 attached to the tip of the handle portion 2. In the operating lever 18, a stopper piece 27 bent in a hook shape is provided at one end portion on the swinging side so as to be freely engaged with and disengaged from each locking groove 20 of the gear cutting member 16. Further, a push operation unit 28 is provided at the other end on the swing side.
