Abstract

A push mower comprises a mower main body, at least one arm extending upward toward a rear side from the mower main body, and a grip located at a tip end of the at least one arm. Each end of the grip is located on one plane side of an arm plane, a center of the grip is located on an opposite plane side of the arm plane, and therefore the grip extends so as to intersect with the arm plane. Here, the arm plane means a virtual plane on which the at least one arm is located and that is parallel to a left-to-right direction of the mower main body.

Claims

1. A push mower comprising:

two arms, comprising a first arm and a second arm, extending upward toward a rear side from the mower main body, each of the two arms comprising a base end and tip end, the mower main body being located at and configured to be attached to the base end of each arm of the two arms; and

a first connecting portion and a second connecting portion that respectively extend from the first arm and the second arm toward the respective first grip and second grip, wherein

each of the two arms has a straight section that linearly extends between the base end and the tip end, and each straight section of the two arms having a longitudinal axis that linearly extends along a center of the straight section,

the straight sections of the two arms define an arm plane, wherein the arm plane is a virtual plane containing each longitudinal axis of the straight sections of the two arms,

the first and the second curved portions extend along a common plane that intersects with the arm plane,

the first connecting portion and the second connecting portion each extend out of the arm plane in a direction toward one side of the arm plane,

the first grip extends from a part of the first connecting portion that is located on the one side of the arm plane, and the second grip extends from a part of the second connecting portion that is located on the one side of the arm plane, and

the first and the second curved portions extend from the one side of the arm plane to the other side of the arm plane and pass through the arm plane.

2. The push mower as in claim 1, wherein

the first and second connecting portions extend to a lower side of the arm plane,

the first grip extends from the part of the first connecting portion to an upper side of the arm plane, and

the second grip extends from the part of the second connecting portion to the upper side of the arm plane.

3. The push mower as in claim 1, wherein

the first and second grips each intersect grip intersects with a virtual line that is coaxial with the first arm, and

the second grip intersects with a virtual line that is coaxial with the second arm.

4. The push mower as in claim 1, wherein the first grip and the second grip are connected with each other.

5. The push mower as in claim 1, wherein the common plane along which the first and the second curved portions extend is perpendicular to the arm plane.

6. The push mower as in claim 1, wherein the first and the second grips are separated from each other.

7. The push mower as in claim 1, wherein the base end of each of the two arms is directly connected to the mower main body so as to be connected rotatably about a common rotation axis with respect to the mower main body, and the common rotation axis is parallel to the arm plane.

8. The push mower as in claim 1, each of the first and the second curved portions has an arc-like shape.

9. The push mower as in claim 1, wherein

the first and second curved portions are positioned to pass through the arm plane such that, when a user grips the first and second grips, the user'"'"'s hands are positioned at the arm plane so that the user can exert force in the arm plane.

10. The push mower as in claim 1, wherein

the first and second connecting portions extend from the tip ends of the first and second arms, respectively.

11. The push mower as in claim 1, wherein each of the first and second connecting portions has a columnar shape.

12. The push mower as in claim 1, wherein

the first connecting portion connects to a first end of the first grip, and

the second connecting portion connects to a first end of the second grip.

13. The push mower as in claim 1, wherein

the first and second connecting portions extend rearwardly, with respect to the mower main body, from the first and second arms towards the first and second grips, respectively.

14. A push mower comprising:

a mower main body;

a first grip configured to be gripped by one hand of a user, the first grip having a first curved portion, the first curved portion having a center axis extending coaxially with the first curved portion;

a second grip configured to be gripped by another hand of the user, the second grip having a second curved portion, the second curved portion having a center axis extending coaxially with the second curved portion;

two arms, comprising a first arm and a second arm, extending upward toward a rear side from the mower main body, each of the two arms comprising a base end and tip end, the mower main body being located at and configured to be attached to the base end of each of the two arms; and

a first connecting portion and a second connecting portion that respectively extend from the first arm and the second arm toward the respective first grip and second grip, wherein

each of the two arms has a straight section that linearly extends between the base end and the tip end, and each straight section of the two arms having a longitudinal axis that linearly extends along a center of the straight section,

the straight sections of the two arms define an arm plane, wherein the arm plane is a virtual plane containing each longitudinal axis of the straight sections of the two arms,

the center axis of the first curved portion and the center axis of the second curved portion extend along a common plane that intersects with the arm plane,

the first connecting portion and the second connecting portion each extend out of the arm plane in a direction toward one side of the arm plane,
