DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water droplet removing device used for removing water droplets attached to an automobile body or the like.

[0002]

2. Description of the Related Art A water drop remover of this type generally has an elongated blade holder made of rubber or the like having a resilient blade made of rubber or the like held on a synthetic resin elongated blade holder having a handle. Configuration. In this water drop remover, for example, a handle provided on the blade holder is held by hand, and the tip of the blade gently rubs the car body after car washing to remove water drops remaining on the body surface. Done.

Conventionally, as such a water droplet removing device, one described in, for example, Japanese Utility Model Application Laid-Open No. 60-47452 has been known. In this device, one end of a handle is slidably attached to an elongated blade holder in a cantilevered state.

[0004] According to such a water drop removing device, the handle is slid with respect to the blade holder and the blade holder is protruded forward from the handle or pulled in toward the front, so that water drops at a distant place or a close place are removed. When removing the water droplet removing device, there is the advantage that the whole of the water droplet removing device can be lengthened or shortened and used properly.

[0005]

However, in the conventional water drop removing tool proposed in the above publication, the handle is attached to the blade holder at one end thereof as described above, and the blade is removed. Since a synthetic resin molded body having a not so large bending rigidity is used as the holding body or the handle, the handle easily fluctuates even when the whole body is lengthened or shortened.

The present invention has been made under the above circumstances. By devising the structure of the connecting portion between the blade holder and the handle and the state of support of the handle by the blade holder, the overall length is improved. To provide a water drop remover such that both the one end and the other end of the handle are firmly and stably supported by the blade holder when the handle is shortened. With the goal.

[0007]

According to a first aspect of the present invention, there is provided a water droplet removing device having a handle attached to an elongated blade holder for holding a blade. One of a seat provided at a position deviated to the left or right and a pedestal provided at one end of the handle opposite to the seat, and the other is rotatable with the above-mentioned tube. The shaft portions fitted slidably in the axial direction are provided, respectively, and a spring body is provided for urging the pedestal and the pedestal in a direction in which the pedestal and the pedestal are always drawn. A groove that can be fitted to each other at a position rotated by 180 degrees to prevent relative rotation between the seat and the pedestal by the fitting, and a protrusion that can be fitted into and removed from the groove, the seat surface of the seat and the seat of the pedestal. provided distributed on the surface to each other, Put the other end and the blade holder of the hand

[0009]

In the water drop remover according to the first aspect of the present invention, the state in which the groove and the projection are fitted to prevent relative rotation between the seat of the blade holder and the seat of the handle is determined. Are secured at two positions that are relatively rotated by 180 degrees.
From the state where the relative rotation between the seat of the blade holder and the pedestal of the handle is prevented, when the seat of the blade holder and the pedestal of the handle are pulled apart against the force of the spring body, the groove, the protrusion, Is released, and the seat of the blade holder and the pedestal of the handle can be rotated. When this rotation is performed and the seat and the pedestal are pulled by the force of the spring body at a position different by 180 degrees to fit the groove and the projection, the relative rotation between the seat of the blade holder and the pedestal of the handle is performed. Is blocked. In these cases, since the receiving seat is provided at a position deviated in the left or right direction from the longitudinal center portion of the blade holder, in the above two states, the entire length of the water droplet removing device is reduced. It can be switched between long and short. Also, when the entire water drop remover is shortened,

In the water drop removing device according to the second aspect of the present invention, the bulging portion of the plate piece housed in the groove is locked by the locking portion, and the relative rotation between the seat of the blade holding body and the pedestal of the handle is performed. The blocked state is ensured at two positions where the receiving seat and the pedestal are rotated by 180 degrees relative to the shaft portion rotatably fitted to the cylindrical portion. Since the seat is provided at a position deviated in the left or right direction from the central portion in the longitudinal direction of the blade holder, in the above two states, the entire length of the water droplet removing tool is two types of short and long. Is switched to. Also, when the entire water drop remover is shortened,
The engaged portion of the ridge is fitted to the engaging portion of the ridge, and the receiving surface is seated.
Overlap on the surface. This allows the handle to move between one end and the other end.
