Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a support structure for a pressing lever in cutting melons.

(Problems to be solved by conventional techniques and ideas) Conventionally, in this type of support structure, support pins are usually provided on the lower blade body and the upper blade body, as shown in Japanese Utility Model Application Publication No. 55-146007. is rotatably penetrated through the support pin, and the head formed at the lower end of this support pin is locked to the lower surface of the lower blade body, and the head formed at the base end of the pressing operation lever on the upper blade body. The upper end of the support pin is inserted into the notched recess, and the support shaft is inserted into the insertion hole penetrated through the base end of the pressing lever and the upper end of the support pin. In this melon cutting,
After the pressing operation lever is molded, an insertion hole for inserting the support shaft must be formed at its base end, and a process for forming the hole is absolutely necessary.

In addition, in order to solve the above problem, it is possible to form the pressing operation lever from a plate material and provide a bent part at the base end of the lever to form an insertion hole for inserting the support shaft, but in this case, There was a problem in that when the pressing operating lever was pressed down, the load portion of the same lever made of plate material was bent, making it impossible to bring the cutting edges of the upper and lower blade bodies into contact with each other.

Therefore, by making it possible to form the insertion hole for inserting the support shaft at the same time as forming the pressing operation lever, it is possible to omit the process of machining the hole, and even if the pressing operation lever is formed of a plate material, the load part of the lever can be The present invention provides a way to cut melon without bending.

Structure of the invention (means for solving problems) That is, as shown in the drawings of the embodiments described later, the present invention has a support pin 5 that passes through the lower blade body 1 and the upper blade body 2, and this support pin In the melon cutting in which the base end of the pressing lever 8 on the upper blade body 2 is connected to the upper end of the pressing lever 8, the pressing lever 8 is connected to the base portion 9 made of a plate material.
and a folding plate part 1 which is bent at the tip of the substrate part 9.
0 and a bent part 11 formed by bending the base end of the base plate part 9, and the end part 14 of the folded plate part 10 is brought into contact with the inner surface of the end part 13 of the bent part 11. , these both end portions 13 and 14 form a force point F for the upper blade body 2, and the inside of the bent portion 11 is an insertion hole 12, and the upper end of the support pin 5 is inserted into the insertion hole 12. The attached support shaft 16 is inserted therethrough.

(Function) With the above structure, when the pressing operation lever 8 is formed by bending the plate material, the insertion hole 12 for inserting the support shaft is formed inside the bent part 11. and,
When the pressing operation lever 8 connected to the support pin 5 via the support shaft 16 is pushed down, the bending part 11 is prevented from bending at the force point F, so that the bending part 11
The upper blade body 2 is pressed, and the cutting edges 2a, 1a of the upper and lower blade bodies 2, 1 come into contact with each other.

(Example) An example embodying the present invention will be described below with reference to the drawings.

The lower blade body 1 and the upper blade body 2 are fixed to each other at their base ends 3, and have cutting edges 1a and 2 formed at their tips.
It has elasticity in the vertical direction on the a side. The upper and lower blade bodies 2, 1 have their cutting edges 2a, 1a.
A loose fitting hole 4 is provided slightly closer to the proximal end. A support pin 5 is rotatably passed through the loose fitting hole 4, and a head 6 formed at the lower end of the support pin 5 is latched to the lower surface of the lower blade body 1. The upper end of the support pin 5 protrudes above the upper blade body 1, and an insertion hole 7 is formed in the upper end.

The pressing lever 8 is formed by bending a plate material, and consists of a base plate part 9 and a folded plate part 10 formed by bending at the tip thereof, which are overlapped with each other. A U-shaped bent portion 1 is provided at the base end of the base plate portion 9.
1 is bent toward the folding plate portion 10 side, and an insertion hole 12 is formed inside this bent portion 11 . The end portion 14 of the folding plate portion 10 is in contact with the inner surface of the end portion 13 of the bent portion 11 . Further, the U-shaped bent portion 11 is formed with a long hole-shaped notch 15 that is bent in a U-shape from the end portion 13 to the base end of the base plate portion 9, and the support pin 5 is formed in this notch 15. The upper end of is inserted. A support shaft 16 is inserted through the insertion hole 12 of the pressing operation lever 8 into the insertion hole 7 at the upper end. Thereby, the pressing operation lever 8 can be rotated in the vertical direction on the upper blade body 2.

Now, in the usage conditions shown in Figures 1 to 3,
The end 13 side of the bent portion 11 of the pressing operation lever 8 is held between the upper blade body 2 and the support shaft 16 by the elastic force of the upper blade body 2. From this state, when the pressing operation lever 8 is pushed down as shown in FIGS. 4 and 5, the upper blade body 2 is pressed by the edge 13a of the bent part 11, and the cutting edges 2a, 1a of the upper and lower blade bodies 2, 1 are pressed down. touch each other. At this time, the end portion 14 of the folding plate portion 10 comes into contact with the inner surface of the end portion 13 of the bending portion 11 to prevent the bending portion 11 from being bent. Note that the end portion 13 of the bent portion 11 and the end portion 14 of the folded plate portion 10 constitute a point of effort F for the upper blade body 2.

On the other hand, if the pressing operation lever 8 is reversed from this used state and superimposed on the upper blade body 2, it can be brought into the unused state shown in FIGS. 6 to 8.

Effects of the Invention In short, according to the present invention, by molding the pressing operation lever 8, the insertion hole 12 for inserting the support shaft can be formed at the same time, so the process of forming the hole 12 can be omitted. Therefore, manufacturing costs can be reduced. Further, the end 13 of the bending part 11 and the end 14 of the folding plate part 10 form a force point F for the upper blade body 2, and the pressing operation lever 8
When pressed down, the bending part 11 is prevented from bending at the force point F, so the bending part 11 can press the upper blade body 2, and the cutting edges 2a,
1a can be brought into contact with each other.
