Abstract

A gardening trimmer may include: a first blade; a facing member overlapping with the first blade in a second direction perpendicular to a first direction; and a suppressing structure. Grease may be applied to at least a part of a conversion mechanism. The first blade may include: a plurality of first slots; and a plurality of pairs of first connecting portions, wherein each pair of the first connecting portions is disposed at opposite ends of corresponding one of the first slots in a third direction perpendicular to the first and second directions. The suppressing structure may be configured to suppress the grease from moving toward a front end of the first blade in the first direction. The suppressing structure may be disposed on the facing member at a position facing at least one pair of in the second direction when the first blade reciprocates relative to the facing member.

First claim

What is claimed is:

1 . A gardening trimmer comprising:
a prime mover; a conversion mechanism comprising a center shaft and configured to convert a rotational movement of the prime mover to a reciprocating movement along a first direction; a first blade connected to the conversion mechanism; and a facing member overlapping with the first blade in a second direction perpendicular to the first direction, wherein the first blade is configured to reciprocate relative to the facing member along the first direction in conjunction with operation of the conversion mechanism, grease is applied to at least a part of the conversion mechanism, the first blade includes:
a plurality of first slots disposed along the first direction; and
a plurality of pairs of first connecting portions, wherein each pair of the first connecting portions is disposed at opposite ends of corresponding one of the first slots in a third direction perpendicular to both the first direction and the second direction,
the gardening trimmer further comprises a suppressing structure configured to suppress the grease from moving toward a front end of the first blade in the first direction, and the suppressing structure comprises a cutout defined inward from an outer edge of the facing member in the third direction and penetrating the facing member in the second direction from a surface located on one side of the facing member in the second direction to a surface located on another side of the facing member in the second direction, and a portion of the cutout penetrating in the second direction on the facing member is at a position facing at least one pair of the first connecting portions in the second direction when the first blade reciprocates relative to the facing member.

2 . The gardening trimmer according to claim 1 , wherein the suppressing structure is disposed on the facing member at a position facing, in the second direction, one pair of the plurality of first connecting portions closest to a rear end of the first blade in the first direction when the first blade reciprocates relative to the facing member.

3 . The gardening trimmer according to claim 1 , wherein the suppressing structure is further disposed on a surface of the first blade facing the facing member.

4 . The gardening trimmer according to claim 3 , wherein the suppressing structure is disposed on a portion of the first blade other than the first connecting portions.

5 . The gardening trimmer according to claim 1 , wherein the facing member comprises a plate member configured to reduce sliding resistance applied by reciprocating movement of the first blade.

6 . The gardening trimmer according to claim 1 , further comprising a plate member overlapping with the first blade in the second direction,
wherein the facing member comprises a second blade, and the first blade and the second blade are configured to reciprocate relative to the plate member along the first direction in conjunction with the operation of the conversion mechanism.

7 . The gardening trimmer according to claim 1 , wherein the first blade includes a plurality of first blade edges disposed on opposite outer edges in the third direction.

8 . The gardening trimmer according to claim 1 , wherein the prime mover comprises an electric motor.

9 . The gardening trimmer according to claim 1 , wherein the suppressing structure is further disposed on a surface of the first blade facing the facing member,
the suppressing structure is disposed on a portion of the first blade other than the first connecting portions, the facing member comprises a plate member configured to reduce sliding resistance applied by reciprocating movement of the first blade, the first blade includes a plurality of first blade edges disposed on opposite outer edges in the third direction, and the prime mover comprises an electric motor.
