Abstract

A wheel cover including a first cover attachable to a body of a power tool and a second cover removably attachable to the first cover reduces rattling of the second cover. The wheel cover includes a first cover attachable to a body of the power tool to cover at least a portion of a first surface of the tip tool adjacent to the body of the power tool, a second cover removably attachable to the first cover to cover at least a portion of a second surface of the tip tool opposite to the body of the power tool, and a rattle restrainer that reduces, while the second cover is attached to the first cover, rattling of the second cover relative to the first cover.

First claim

The invention claimed is:

1. A wheel cover for covering a disk-shaped tip tool attached to an output shaft of a power tool, the wheel cover comprising:
a first cover attachable to a body of the power tool to cover at least a portion of a first surface of the tip tool, the first surface being adjacent to the body of the power tool;
a second cover removably attachable to the first cover to cover at least a portion of a second surface of the tip tool, the second surface being opposite to the body of the power tool; and
a rattle restrainer configured to reduce, while the second cover is attached to the first cover, rattling of the second cover relative to the first cover,
wherein:
the rattle restrainer is configured to reduce rattling of the second cover at least in a radial direction of the tip tool intersecting with the output shaft or in an axial direction parallel to the output shaft,
the first cover includes:
a first plate face protector facing the first surface of the tip tool to protect a first plate face of the tip tool, and
a first periphery protector facing a peripheral edge of the tip tool about the output shaft to protect a periphery of the tip tool,

the second cover includes:
a second plate face protector facing the second surface of the tip tool to protect a second plate face of the tip tool, and
a second periphery protector facing the peripheral edge of the tip tool about the output shaft to protect the periphery of the tip tool,

the second cover is attachable to the first cover to have the second periphery protector overlapping the first periphery protector, and
the rattle restrainer includes at least one first elastic strip to urge the first periphery protector and the second periphery protector away from each other.

2. The wheel cover according to claim 1 , wherein
the at least one first elastic strip includes an elastic strip in the first periphery protector or the second periphery protector, and the elastic strip in the first periphery protector or the second periphery protector is movable in the radial direction.

3. The wheel cover according to claim 2 , wherein
the first elastic strip is integral with the first periphery protector or the second periphery protector across a cutout.

4. The wheel cover according to claim 2 , wherein
the first elastic strip is a member separate from the first cover and separate from the second cover, and is fixed to the first periphery protector or the second periphery protector.

5. The wheel cover according to claim 1 , wherein
the at least one first elastic strip is located between the first periphery protector and the second periphery protector in a deformable manner.

6. The wheel cover according to claim 5 , wherein
the at least one first elastic strip comprises elastic rubber, a sponge, or an elastomer.

7. The wheel cover according to claim 1 , wherein
the at least one first elastic strip includes a plurality of first elastic strips along the first periphery protector or the second periphery protector in a circumferential direction.

8. The wheel cover according to claim 1 , wherein
the second cover has a second curved portion on an end of the second periphery protector opposite to an end adjacent to the second plate face protector to hold the first periphery protector between the second curved portion and the second plate face protector,
the second cover is attachable to the first cover to have the second periphery protector overlapping the first periphery protector and the first periphery protector held between the second plate face protector and the second curved portion, and
the rattle restrainer includes at least one second elastic strip to urge the second curved portion away from the first plate face protector.

9. The wheel cover according to claim 8 , wherein
the at least one second elastic strip includes an elastic strip in the second curved portion, and the elastic strip in the second curved portion is movable in the axial direction.

10. The wheel cover according to claim 9 , wherein
the elastic strip in the second curved portion is integral with the second curved portion across a cutout.

11. The wheel cover according to claim 8 , wherein
the at least one second elastic strip is located between the second curved portion and the first cover in a deformable manner.

12. The wheel cover according to claim 8 , wherein
the at least one second elastic strip includes a plurality of second elastic strips in the second curved portion along the second periphery protector in a circumferential direction.

13. The wheel cover according to claim 1 , wherein
the second cover is attachable to the first cover to have the second periphery protector overlapping the first periphery protector, and
the rattle restrainer includes a spring to urge the first periphery protector and the second periphery protector to be in direct contact with each other.

14. The wheel cover according to claim 13 , wherein
the second periphery protector covers the first periphery protector,
the second cover includes
a bend located on a first circumferential end of the second periphery protector and engageable with a first circumferential end of the first periphery protector, and
a clip located on a second circumferential end of the second periphery protector and deformable in a circumferential direction of the second periphery protector, and the clip is manually engageable with a second circumferential end of the first periphery protector when the second cover is attached to the first cover, and

the spring is located on the second circumferential end of the second periphery protector to urge the clip from the second circumferential end toward a middle of the second periphery protector.

15. The wheel cover according to claim 14 , wherein
the clip includes a push tab operable to displace the clip toward the second circumferential end of the second periphery protector against an urging force from the spring.

16. The wheel cover according to claim 15 , wherein
the second periphery protector holds a support shaft orthogonal to the circumferential direction of the second periphery protector on an outer peripheral surface on the second circumferential end of the second periphery protector, and
the clip is axially supported on the support shaft in a manner swingable between an engagement position at which the clip is engageable with the second circumferential end of the first periphery protector and a retracted position at which the clip is retracted from the engagement position.

17. The wheel cover according to claim 16 , wherein
the second periphery protector includes, on the outer peripheral surface on the second circumferential end of the second periphery protector, a retainer engageable with the clip to retain the clip at the retracted position when the clip is displaced toward the second circumferential end of the second periphery protector against the urging force from the spring.

18. A wheel cover for covering a disk-shaped tip tool attached to an output shaft of a power tool, the wheel cover comprising:
a first cover attachable to a body of the power tool to cover at least a portion of a first surface of the tip tool, the first surface being adjacent to the body of the power tool, the first cover including
a first plate face protector facing the first surface of the tip tool to protect a first plate face of the tip tool, and
a first periphery protector facing a peripheral edge of the tip tool about the output shaft to protect a periphery of the tip tool; and

a second cov
