FIELD OF THE INVENTION
The present invention relates generally to a hose winder, and more particularly to a hose guiding device which is used to facilitate the winding of the hose on a reel of the hose winder and the unwinding of the hose from the reel of the hose winder.
BACKGROUND OF THE INVENTION
As shown in
FIG. 5
, a hose winder of the prior art is provided with a guide hole
40
in communication with a chamber
41
in which a first roller
43
is mounted on a shaft
42
and a second roller
44
is mounted on another shaft
42
. The two rollers
43
and
44
are opposite to each other and are separated from each other by a gap equal to the thickness of a flattened hose
45
of the hose winder. The hose
45
runs through the gap between the two rollers
43
and
44
when the hose
45
is reeled out or reeled in via the guide hole
40
. When the hose
45
is reeled in after use, the hose
45
is flattened by the two rollers
43
and
44
so as to eject the residual fluid of the hose
45
. The two rollers
43
and
44
are susceptible to being jammed by a foreign object that is attached to the hose
45
at the time when the hose
45
is being reeled in. The gap between the two rollers
43
and
44
is fixed. As a result, the prior art hose winder is not compatible with hoses of various specifications.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a hose winder with a hose guiding device which is free of the deficiencies of the prior art hose winder described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a hose guiding device comprising a housing in which two rollers are mounted respectively on a shaft slidable along an inclined track of a predetermined length. The hose guiding device is prefabricated for fast assembly with a hose winder frame and is compatible with hoses of various specifications.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
