Abstract

A barrel for an implement adapted to be gripped by user'"'"'s fingers in use, comprises a substantially cylindrical body having a finger gripping area and an outer circumferential recess portion provided around the finger gripping area, an elastic finger gripping member mounted within the circumferential recess portion of the cylindrical body, the finger gripping member having a body of a substantially tubular shape, and a cooperating device for facilitating secure fitting of the finger gripping member within the recess portion of the cylindrical body.

Claims

1. A barrel for an implement adapted to be gripped by user'"'"'s fingers in use, said barrel comprising:

a substantially cylindrical body having a finger gripping area and an outer circumferential recess portion provided around at least said finger gripping area;

finger gripping means mounted within said circumferential recess portion of said cylindrical body, said finger gripping means having an inner surface contacting with a surface of the circumferential recess portion;

said finger gripping means made of elastic material and having a solid body of a substantially tubular shape and first and second ends, said finger gripping means having a same outer circumference over the finger gripping area; and

cooperating means on said cylindrical body and finger gripping means for securely fitting said finger gripping means within said circumferential recess portion of said cylindrical body in order to prevent movement of the gripping means;

said cooperating means comprising;

at least one projection projecting radially inwardly from the inner surface of said finger gripping means;

at least one dent portion formed in a bottom surface of said circumferential recess portion of said cylindrical body; and

said finger gripping means mounted within said circumferential recess portion with said at least one projection being fitted in said at least one dent portion of said cylindrical body.

2. A barrel as defined in claim 1, wherein said cylindrical body comprises:

a first barrel member having first and second ends,

a second barrel member connected at one end of said first end of said first barrel member, and

a head member connected to said second end of said first barrel member.

3. A barrel as defined in claim 2, wherein said cylindrical body is formed as a one-piece member having said first and second barrel members and said head member.

4. A barrel as defined in claim 1, wherein said circumferential recess portion is provided around an entire length of said cylindrical body including said finger gripping area of said cylindrical body, and said finger gripping means has a length substantially corresponding to the length of said recess portion.

5. A barrel for an implement adapted to be gripped by user'"'"'s fingers in use, said barrel comprising:

a substantially cylindrical body having a finger gripping area and an outer circumferential recess portion provided around at least said finger gripping area;

finger gripping means mounted within said circumferential recess portion of said cylindrical body, said finger gripping means having an inner surface contacting with a surface of the circumferential recess portion;

said finger gripping means made of elastic material and having a solid body of a substantially tubular shape, and first and second ends, said finger gripping means having a same outer circumference over the finger gripping area; and

cooperating means on said cylindrical body and finger gripping means for securely fitting of said finger gripping means within said recess portion of said cylindrical body in order to prevent movement of the gripping means;

cooperating means comprising;

at least one projection projecting radially from a region of a bottom surface of said recess portion;

at least one dent portion formed in a region of an inner surface of said finger gripping means;

said finger gripping means mounted within said recess portion of said cylindrical body with said at least one dent portion being engaged with said at least one projection.

6. A barrel as defined in claim 5, wherein said cylindrical body comprises:

a first barrel member having first and second ends,

a second barrel member connected at one end thereof to said first end of said first barrel member, and

a head member connected to said second end of said first barrel member.

7. A barrel as defined in claim 6, wherein said cylindrical body is formed as a one-piece member having said first and second barrel members and said head member.

8. A barrel as defined in claim 6, wherein said circumferential recess portion is provided around a total length of said cylindrical body including said finger gripping area of said cylindrical body, and said finger gripping means has a length substantially corresponding to the length of said circumferential recess portion.
