Abstract

A grip for a backpack-type air blowing machine which performs a work by using air discharged from a distal end of an air blowing pipe that is coupled to a blower body driven by a power source while the air blowing pipe is manipulated by an operator with the power source and the blower body being carried on a back of the operator. The grip comprises a base section that constitutes an attachment section to the air blowing pipe, a vertical grip section that is provided with a proximal end portion provided continuously to the base section, and that extends in a direction away from the air blowing pipe, and a lateral grip section that extends backward along the air blowing pipe from a free end of the vertical grip section. The lateral grip section is located adjacent to a back of a hand of the operator holding the air blowing pipe.

First claim

What is claimed is:

1. A grip for a backpack-type air blowing machine which performs a work by using air discharged from a distal end of an air blowing pipe that is coupled to a blower body driven by a power source while the air blowing pipe is manipulated by an operator with the power source and the blower body being carried on a back of the operator, comprising:
a base section that constitutes an attachable section to an air blowing pipe of a backpack-type air blowing machine;
a vertical grip section that is provided with a proximal end portion provided continuously to the base section; and
a lateral grip section that is provided continuously to a free end of the vertical section and extends in a direction apart laterally from the vertical grip section,
wherein the proximal end portion of the vertical grip section has a shape with a thickness capable of being sandwiched between a thumb and a forefinger of the operator, and
the vertical grip section further includes an upper portion above and thicker than the proximal end portion and a step portion between the proximal end portion and the upper portion, wherein the step portion is configured to restrict a thumb, forefinger, and crotch between the thumb and the forefinger engaged with the proximal end portion from slipping out to the upper portion.

2. The grip for a backpack-type air blowing machine of claim 1 , wherein the step portion is formed into a rounded shape.

3. The grip for a backpack-type air blowing machine of claim 2 , wherein the lateral grip section is inclined outward when viewed in a top plan view of the grip.

4. The grip for a backpack-type air blowing machine of claim 3 , wherein a rear end portion of the lateral grip section has a downward curved or bent shape.

5. The grip for a backpack-type air blowing machine of claim 1 , wherein the lateral grip section is inclined outward when viewed in a top plan view of the grip.

6. The grip for a backpack-type air blowing machine of claim 5 , wherein a rear end portion of the lateral grip section has a downward curved or bent shape.

7. The grip for a backpack-type air blowing machine of claim 1 , wherein the vertical grip section has a shape gradually curved backward as is apart from the proximal end portion when viewed in a left or right side view of the grip.

8. The grip for a backpack-type air blowing machine of claim 7 , wherein a coupling portion between the vertical grip section and the lateral grip section has a rounded profile.

9. The grip for a backpack-type air blowing machine of claim 1 , wherein the lateral grip section has a rear end portion, a lower surface of the rear end portion is curved downward.

10. The grip for a backpack-type air blowing machine of claim 9 , wherein the rear end portion of the lateral grip section has a free end.
