Abstract

A hydraulic excavator is a work vehicle equipped with a work implement, including a cab and a rotating light. The rotating light is removably disposed on a roof of the cab. The rotating light has a rotating light main body, an attachment component, and a handle. The attachment component is provided on the lower side of the rotating light main body and is used to attach the rotating light main body to the roof. The handle is portal-shaped and fixed to the attachment component, and has a first rod-shaped part, a second rod-shaped part, and a third rod-shaped part. The first rod-shaped part and the second rod-shaped part are formed facing upward from the attachment component. The third rod-shaped part connects the first rod-shaped part and the second rod-shaped part together. The third rod-shaped part is disposed above the rotating light main body when viewed from the side and perpendicular to the lengthwise direction.

First claim

The invention claimed is:

1. A work vehicle equipped with a work implement, comprising:
a cab having a roof provided to the upper part, the cab having a first lateral side face and a second lateral side face; and
a base component fixed to an upper face of the roof;
a rotating light removably attached to the base component,
the rotating light including
a rotating light main body,
an attachment component on which the rotating light main body is arranged, the attachment component being disposed underneath the rotating light main body and configured to be attached to the base component, the attachment component and the base component being configured to engage with each other such that the rotating light assumes a prescribed attachment position when the rotating light is attached to the base component, and
a portal-shaped handle non-movably fixed to the attachment component,

the handle having a first rod-shaped part and a second rod-shaped part that extend upward from the attachment component, and a third rod-shaped part that connects the first rod-shaped part and the second rod-shaped part together,
the first rod-shaped part being disposed forward of the second rod-shaped part in a lengthwise direction of the work vehicle, the first rod-shaped part being disposed more to the second lateral side face side than the rotating light main body, and the first rod-shaped part being superposed with the rotating light main body when the rotating light is viewed from the second lateral side face of the cab while the rotating light is in the prescribed attachment position with respect to the base component,
the second rod-shaped part being disposed to the rear of the rotating light main body, and disposed more to the first lateral side face side than the first rod-shaped part, and
the third rod-shaped part being disposed at a position higher than a height of the rotating light main body in a vertical direction of the work vehicle such that an upper surface of the third rod-shaped member forms an uppermost surface of the entire rotating light.

2. The work vehicle according to claim 1 , wherein
part of the third rod-shaped part is superposed with the rotating light main body in a plan view of the work vehicle.

3. The work vehicle according to claim 2 , wherein
the rotating light main body has
a base member fixed to the attachment component;
a light source disposed on the inside of the base member; and
a cover member that covers the light source from above and is removably attached to the base member,

wherein a gap is formed between the third rod-shaped part and the cover member to allow the cover member to pass through when the cover member is removed from the base member.

4. The work vehicle according to claim 1 , wherein
the work implement is disposed to the side of the first side lateral face of the cab,
the base component is disposed at an end of the roof on the second lateral side face side.

5. The work vehicle according to claim 1 ,
wherein
the base component has
an engagement component capable of engaging with the attachment component; and
a guide component that guides the attachment component to a position where it can be engaged by the engagement component, the guide component having a restrictor that restricts movement of the attachment component in a state of having been engaged with the engagement component after being guided,

the attachment component has:
an engaged component that is engaged to the engagement component; and
a restricted component that is provided on the opposite side of the engaged component, flanking the rotating light main body, and

in a state in which the engagement component has engaged the engaged component, the engaged component is biased downward and the restricted component is biased upward to hit the restrictor to fix the attachment component to the base component.

6. The work vehicle according to claim 5 , wherein
the work implement is disposed to the side of the first side lateral face of the cab,
the base component is disposed at the end of the roof on the second lateral side face side, and
the engagement component and the engaged component are provided on the second lateral side face side of the rotating light main body.

7. The work vehicle according to claim 6 , wherein
the attachment component further has on its lower face a fixing member that magnetically fixes to the base component,
a part of the third rod-shaped part is superposed with the rotating light main body when viewed from above,
the engagement component and the engaged component are disposed in the approximate center of the rotating light main body in the front-back direction when viewed from the side on the opposite side from the work implement, and
the first rod-shaped part is disposed forward of the engagement component and to the outside of the rotating light main body.

8. The work vehicle according to claim 1 , wherein
a bottommost end of at least one of the first and second rod-shaped parts being disposed lower than a bottommost part of the rotating light main body when the attachment component is attached to the roof.

9. A work vehicle equipped with a work implement, comprising:
a cab having a roof provided on an upper portion of the cab, the cab having a first lateral side face and a second lateral side face; and
a base component fixed to an upper face of the roof;
a rotating light removably unattached to the base component,
wherein the rotating light includes
an attachment component configured to be detachably attached to the base component, the attachment component and the base component being configured to engage with each other such that the rotating light assumes a prescribed attachment position when the rotating light is attached to the base component,
a rotating light main body arranged on the attachment component, and
a portal-shaped handle fixed to the attachment component independently from the rotating light main body,

the portal-shaped handle and the rotating light main body both extending upward from the attachment component in a vertical direction of the work vehicle when the attachment component is attached to the roof, an upper portion of the portal-shaped handle being oriented in a diagonal direction with respect to a lengthwise direction of the work vehicle when the rotating light is in the prescribed attachment position with respect to the base component.

10. The work vehicle according to claim 9 , wherein
a bottom surface of the attachment component includes at least one positioning part,
an upper surface of the base component includes at least one receiving part configured to mate with the at least one positioning part when the rotating light is in the prescribed attachment position with respect to the base component, and
the attachment component is arranged in a prescribed orientation with respect to the roof when the at least one positioning part is mated with the at least one receiving part.

11. The work vehicle according to claim 9 , wherein
the attachment component is configured to protrude beyond the rotating light main body in at least one of a lengthwise direction and a widthwise direction of the work vehicle, and
the portal-shaped handle is fixed to a portion of the attachment component that protrudes beyond the rotating light main body.

12. The work vehicle according to claim 9 , wherein
the portal-shaped handle includes a first rod-shaped part, a second rod-shaped part, and a third rod-shaped part, the first and second rod-shaped parts extending upward from the attachment component and the third rod-shaped part connecting upper ends of the first rod-shaped part and the
