Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for scooping up a soft object having a complicated shape.

[0002]

2. Description of the Related Art Conventionally, when a soft object having a complicated shape is to be picked up without using a dedicated box, a flat plate having a size on which the object to be scooped is placed is used, and one side or an object having a mechanism as shown in FIG. I was scooping up. The mechanism shown in FIG. 6 is one in which the first flat plate fixed to the first support rod and the second flat plate fixed to the second support rod scoop up the scooped object from both sides.

[0003]

However, when an object having a complicated shape is placed on the ground, only the convex portion comes into contact with the ground. However, when the object to be scooped is scooped up by the conventional scooping mechanism as shown in FIG. There is a disadvantage that the first flat plate 32 and the second flat plate 33 cannot abut against the portion which is grounded, or that an excessive force is locally exerted during scooping. Therefore, the present invention makes it possible to scoop up a scooped object without exerting a local excessive force on the convex part by utilizing the concave part that is lifted from the ground without being aware of the shape of the scooped object. It was done like this.

[0004]

SUMMARY OF THE INVENTION In the present invention, a support rod, a guide shaft spaced apart from the support rod and arranged substantially parallel to each other, and a longitudinal axis of the guide shaft serving as a rotation shaft. Left wheel and right wheel arranged near both ends of the front shaft, a front first connecting shaft having one end fixed rotatably to the end of the guide shaft in the right wheel direction, and the other end of the front first connecting shaft. A rear first connecting shaft whose both ends are rotatably fixed to the support rod, a front second connecting shaft whose one end is rotatably fixed to the left wheel direction end of the guide shaft, and the front The other end of the second connecting shaft and the rear second connecting shaft whose both ends are rotatably fixed to the supporting rod, the guide shaft, the first front connecting shaft, the first rear connecting shaft, the supporting rod, and the rear rear connecting shaft. The front first connecting shaft in the direction surrounded by the two connecting shafts and the front second connecting shaft,
A rear first connecting shaft, a second rear connecting shaft, and a flat plate-like projection protruding from the second front connecting shaft.

[0005]

In the scooping mechanism of the present invention having the above-mentioned structure, the concave portion raised from the ground is used without being aware of the complicated shape of the object to be scooped up, so that the convex portion is not locally exerted with an excessive force. It is possible to scoop up scooped objects.

The guide shaft 8 arranged substantially in parallel, the left wheel 7, the right wheel 6 arranged near both ends of the guide shaft 8 with the longitudinal direction of the guide shaft 8 as a rotation axis, and the end of the guide shaft 8 in the direction of the right wheel 6 A front first connecting shaft 1 whose one end is rotatably fixed to the other, and a rear first connecting shaft 2 whose other end is rotatably fixed to the other end of the front first connecting shaft 1 and the support rod 9. , The front second connecting shaft 3 having one end fixed rotatably to the end of the guide shaft 8 in the direction of the left wheel 7, and the other end of the front second connecting shaft 3 and the support rod 9 both ends rotatably. Rear second connecting shaft 4 fixed to
And in the direction surrounded by the guide shaft 8, the front first connecting shaft 1, the rear first connecting shaft 2, the support rod 9, the rear second connecting shaft 4, and the front second connecting shaft 3, the front first connecting shaft 1, A main protrusion 10 protruding from the rear first connecting shaft 2, the second rear connecting shaft 4, and the front second connecting shaft 3, and an intermediate protrusion 11 to be inserted after the inside of the main protrusion 10 is filled with a compressible gas or liquid. An intermediate groove stopper 15 for preventing the intermediate protrusion 11 from slipping out of the main protrusion 10, and an intermediate guide groove 13 for guiding the intermediate protrusion 11 in and out of the main protrusion 10 as shown in FIG. A tip projection 12 to be inserted after filling the inside of the intermediate projection 11 with a compressible gas or liquid, and a tip projection 12
And a tip guide groove 1 as shown in FIG. 3C that guides the tip projection 12 when it goes in and out of the intermediate projection 11.
4 are provided. The main projection 10, the intermediate projection 11, the tip projection 12, the intermediate guide groove 13, the tip guide groove 14, the intermediate groove stopper 15, and the tip groove stopper 16 form a flat plate-shaped projection 5.

The scooping mechanism thus constructed is surrounded by the front first connecting shaft 1, the rear first connecting shaft 2, the supporting rod 9, the rear second connecting shaft 4, the second front connecting shaft 3 and the guide shaft 8. When the support rod 9 is pulled in the direction opposite to the guide shaft 8 so that the part to be scooped up can enter the part to be scooped up and the support shaft 9 is pulled in the direction opposite to the guide shaft 8, as shown in FIG.
The edge of 0 touches. When the support rod 9 is further pulled, the front first connecting shaft 1 and the rear first connecting shaft 2 and the front second connecting shaft 3 and the rear second connecting shaft 4 rotate in a straight line. Along with this operation, the flat plate-like projection 5 moves toward the scooped object 20 and rotates. As a result, as for the flat plate-shaped projection 5 that abuts the convex portion of the object 20 to be scooped which is in contact with the ground 21, the intermediate projection 11 is retracted into the main projection 10 and the tip projection 12 is retracted into the intermediate projection 11. Picked up object 2
The flat plate-shaped projection 5 that has protruded from the ground surface 21 of 0 to the concave portion is inserted under the scooped object 20 as shown in FIG. 5A. Then, with the rotation operation, as shown in FIG. 5B, the scooped object 20 is scooped up to the convex portion of the scooped object 20 in contact with the ground 21.

[0008]

According to the present invention, as described above, the use of the concave portion lifted up from the ground without paying attention to the complicated shape of the object to be scooped allows a locally excessive force to be applied to the convex portion. It is possible to scoop up objects to be scooped without affecting.
