Technical Field
-
The present invention relates to a hose reel for winding
up a hose.
Background Art
-
Conventionally, a hose reel is used for winding up a hose
for sprinkling use (see for instance Japanese Patent
Laid-Open No. 2001-206637 (FIG. 1) and Japanese Patent
Laid-Open No. 2001-206638 (FIG. 1)).
-
This hose reel would be composed of a frame and a drum
rotatably supported by the frame. The frame consists of
triangular side plates disposed opposite each other, and the
two side plates are linked with a space between them. A
connecting plug for connecting the faucet side hose protrudes
from one of these side plates, and a handle for turning the
drum protrudes from the other.
-
It is so configured as to wind up and keep the hose around
the drum by turning this handle.
-
However, as the side plates constituting the frame are
disposed with a space between them in this hose reel, the hose
winding side is open. As a result, the hose wound around the
drum is apt to become disorderly in the wound state.
-
Also, there is another type of hose reel consisting of
a frame and a drum rotatably supported by the frame, and the
frame consists of right and left side plates and pipe members
linking the two side plates.
-
Further, the drum is formed of a barrel around which the
hose is to be wound and collars disposed at the two ends of
the barrel.
-
However, as the hose winding side is open in this hose
reel, the hose is apt to be wound into the gap between the
drum and the frame.
-
A hose can be neatly wound by neither of these
conventional hose reels. An object of the present invention,
attempted in view of these problems with the conventional
reels, is to provide a hose reel that can neatly wind up a
hose.
Disclosure of the Invention
-
In order to solve the problem noted above, a hose reel
according to Claim 1 of the present invention is a hose reel for
winding a hose by turning a drum, wherein a guide part for guiding
the hose is provided on the moving path of the hose to be wound
around the drum and the width of the guide part is so set as to
decrease toward its upper portion.
-
Thus, when the hose is wound by turning the drum, the hose
may sometimes concentrate on one end of the drum. However, the
guide part for guiding the hose is provided on the moving path
of the hose, and the width of the guide part is so set as to decrease
toward its upper portion.
-
As a result, the hose wound concentrating on an end of the
drum is guided along the guide part toward the central part when
a prescribed quantity has been wound up.
-
A hose reel according to Claim 2 of the invention is a hose
reel for winding a hose by turning a drum, wherein a guide part
for guiding the hose is provided on the moving path of the hose
to be wound around the drum, a restrictive part for preventing
the hose from escaping is extended on the guide part in a direction
crossing the moving direction of the hose, an inclined part
inclined toward the central part along its upper direction is set
on the restrictive part, and the angle of inclination in the
inclined part is set to be not less than 45 degrees and less than
90 degrees.
-
Thus, when the hose is wound by turning the drum, the hose
may sometimes concentrate on one end of the drum. However, the
guide part for guiding the hose is provided on the moving path
of the hose, and an inclined part inclined toward the central part
along its upper direction is set on the restrictive part set on
the guide part.
-
As a result, the hose wound concentrating on an end of the
drum is guided by the inclined part toward the central part when
a prescribed quantity has been wound up.
-
Then, a downward component of force and a horizontal
component of force arise in the hose that has come into contact
with this inclined part, and the angle of inclination of the
inclined part is set to be not less than 45 degrees and less than
90 degrees. For this reason, the horizontal component of force
is not less than the downward component of force, and the force
guiding the hose stacked to a prescribed quantity toward the
central part is not less than the force pressing the hose downward.
-
Further, a hose reel according to Claim 3 of the invention
is a hose reel for winding a hose by turning a drum, wherein a
guide part for guiding the hose is provided on the moving path
of the hose to be wound around the drum, a restrictive part for
preventing the hose from escaping is extended on the guide part
in a direction crossing the moving direction of the hose, and the
restrictive part is formed in an arc shape whose central part
protrudes.
-
Thus, when the hose is wound by turning the drum, the hose
may sometimes concentrate on one end of the drum. However, the
guide part for guiding the hose is provided on the moving path
of the hose, and the restrictive part set on the guide part is
formed in an arc shape whose central part protrudes.
-
As a result, the hose wound concentrating on an end of the
drum is guided along the guide part in an arc shape toward the
central part when a prescribed quantity has been wound up.
-
Further, in a hose reel according to Claim 4 of the invention,
an opening through which the hose is inserted is provided in the
guide part, the restrictive part is set in the upper opening edge
of the opening, and the lower opening edge of the opening is
linearly formed.
-
Thus, of starting winding of the hose around an empty drum,
the hose to be moved is guided along the lower opening edge of
the opening in the guide part. In this arrangement this lower
opening edge is linearly formed. As a result, the hose is wound
around the whole area of the drum in a distributed way.
-
And when a prescribed quantity of the hose has been wound
up around the drum, it is guided along the restrictive part formed
by the upper opening edge of the opening in the guide part.
-
Further in a hose reel according to Claim 5 of the invention,
the drum is supported by a frame, and the guide part is composed
of a bar disposed on the frame.
-
This contributes to simplification of the configuration.
-
Further in a hose reel according to Claim 6 of the invention
is a hose reel for winding a hose by turning a drum, wherein a
guide part having an opening through which the hose is inserted
is provided on the moving path of the hose to be wound around the
drum, and a thick part thicker than a general part is disposed
on the opening edge of the opening.
-
Thus, the hose to be wound up by the drum is guided to its
prescribed position by being inserted through the opening disposed
in the guide part and brought into sliding contact with the opening
edge of the opening.
-
Herein, a thick part thicker than a general part is disposed
on the opening edge of the opening. As a result, inadvertent
bending of the hose can be more securely prevented than in a case
in which the opening edge is composed of a thin part.
-
Further, a hose reel according to Claim 7 of the invention
is a hose reel for winding a hose by turning a drum, wherein a
guide part having an opening through which the hose is inserted
is provided on the moving path of the hose to be wound around the
drum, and the sectional shape of the opening edge of the opening
is formed in an arc protruding toward the center of the opening.
-
Thus, the hose to be wound up by the drum is guided to its
prescribed position by being inserted through the opening disposed
in the guide part and brought into sliding contact with the opening
edge of the opening.
-
Herein, the opening edge of the opening is formed in an arc
having a sectional shape protruding toward the center of the
opening. As a result, the area of contact with the hose in sliding
contact is reduced.
-
In addition, a hose reel according to Claim 8 of the invention
is a hose reel for winding a hose by turning a drum, wherein a
rotational member in contact with the hose and rotating in the
direction of urging the movement of the hose is disposed on the
moving path of the hose to be wound up by the drum.
-
Thus, the hose to be wound up by the drum comes into contact
with the rotational member disposed on the moving path of the hose.
This rotational member is in contact with the hose and rotates
in the direction of urging the movement of the hose. In this way,
the hose is guided by the rotational member to the drum.
-
And in a hose reel according to Claim 8 of the invention the
outer circumferential face of the hose is made rugged.
-
Thus, when the hose is wound up, the outer circumferential
face of the hose comes into sliding contact with the inner face
of the drum or that of the frame and gives rise to friction.
However, as the outer circumferential face of this hose is rugged,
the frictional resistance to the area of sliding contact is reduced.
The winding of the hose around the drum is further smoothened,
and disorderly winding is prevented.
-
Further in a hose reel according to Claim 10 of the invention
wherein a drum having collars at the two ends of its barrel is
turnably supported by a frame, the frame is formed in a shape
allowing accommodation of the drum, an inlet/outlet for the hose
is disposed in a position in the frame opposite the winding
position between the two collars of the drum, and the width of
the inlet/outlet is set to be not greater than the distance from
one collar of the drum to the other.
-
Thus, the inlet/outlet for the hose is disposed in the
position in the frame opposite the winding position between the
two collars of the drum, and the hose to be wound up by the drum
moves via this inlet/outlet.
-
And the width of this inlet/outlet is set to be not greater
than the distance from one collar of the drum to the other. As
a result, the hose to be accommodated into the frame via the
inlet/outlet is guided to the position between the two collars
of the drum.
-
Further in a hose reel according to Claim 11 of the invention,
the frame is formed in a case shape for accommodating the drum.
-
Thus, the frame turnably supporting the drum is formed in
the case shape allowing accommodation of the drum, the
inlet/outlet for the hose is disposed in the position in the frame
opposite the winding position between the two collars of the drum,
and the hose to be wound up by the drummoves via this inlet/outlet.
-
And the width of the inlet/outlet is set to be not greater
than the distance from one collar of the drum to the other. As
a result, the hose accommodated into the frame via the inlet/outlet
is guided to the position between the two collars of the drum.
-
Further in a hose reel according to Claim 12 of the invention,
the width of the inlet/outlet is set to decrease toward the upper
part.
-
Preferably, as stated in Claim 13 of the invention, the
opening edge of the inlet/outlet on the upper side should be formed
in an arc shape whose central part protrudes upward.
-
Thus, when the hose is wound by turning the drum, the hose
may sometimes concentrate on the collar at one end of the drum.
However, as the width of the inlet/outlet through which the hose
moves is set to decrease toward the upper part, and preferably
the opening edge of the inlet/outlet on the upper side is formed
in an arc shape whose central part protrudes upward.
-
As a result, the hose wound concentrating on the end of the
drum is guided along the opening edge of the inlet/outlet,
preferably along an opening edge in the arc shape, toward the
central part when a prescribed quantity has been wound up.
-
In addition, in a hose reel according to Claim 14 of the
invention, the starting point of the arc shape of the opening edge
is set between the center of rotation of the drum and the highest
position of the collars.
-
As a result, the hose to be wound concentrating on the collars
side of the end of the drum, before reaching the highest position
of the collars, is guided toward the central part along the opening
edge of the arc shape.
-
Further in a hose reel according to Claim 15 of the invention,
a drum having collars at the two ends of its barrel is turnably
supported by a frame, the distance between the two collars is set
between 40% and 60% of the diameter of the collars.
-
Thus, the distance between the two collars provided at the
two ends of the barrel of the drum around which the hose is to
be wound is set between 40% and 60% of the diameter of the collars.
When the hose is wound around such a drum, even if the hose is
wound concentrating on one of the collars, a collapse will arise
within. For this reason, the hose is guided to a position between
the two collars by being wound around this drum.
-
Herein, though the winding ease of the hose can be improved
by reducing the distance between the collars of the drum, but if
the distance between the collars is made too small, the drum will
become thin and apt to fall down. In view of this factor, repeated
experiments have led to a discovery that the two requirements can
be made consistent with each other by setting the distance between
the collars of the drum to between 40% and 60% of the diameter
of the collars.
-
As a result, the invention according to which the distance
between the collars of the drum is set to between 40% and 60% of
the diameter of the collars enables the winding ease to be improved
without sacrificing the resistance of the drum to falling down.

Best Modes for Carrying Out the Invention
-
The present invention will be described in more detail
with reference to the accompanying drawings.
(First Embodiment)
-
A first mode for implementing the invention will be
described below with reference to drawings. FIG. 1 shows a
hose reel 1 in this embodiment, the hose reel 1 being intended
for use in winding up a hose for the sprinkling purpose.
-
This hose reel 1 is provided with a rectangular body case
11 constituting a frame, and the body case 11 as shown in FIG.
2, formed by coupling a lower vessel 12 of a container shape
opening upward and an upper vessel 13 of a container shape
opening downward. This body case 11, as shown in FIG. 3,
accommodates a drum 15 for winding up a hose 14, and the drum
15 comprises a cylindrical barrel 17 around which the hose
14 having penetrated a hose inserting hole 16 is wound and
collars 18 and 18 disposed at the two ends of the barrel 17.
-
The top plate 21 of the upper vessel 13, as shown in FIG.
1 and FIG. 4, is formed in a rectangular flat shape. The top
plate 21, set to be large enough to permit the mounting of
another hose reel on the body case 11, constitutes a load
carrier.
-
A C-shaped concave 22 is formed in this top plate 21,
and a C-shaped handle 23 is arranged in the concave 22. The
handle 23 is composed of a grip 24 constituting a free end
and extension parts 25 and 25 extending from the two ends of
the grip 24 into the C shape, and turnably supported by the
upper vessel 13 via rotation shafts 26 and 26 disposed at the
tips of the extension parts 25 and 25 as shown in FIG. 5. In
this way, the handle 23 is so configured as to be turnable
between an inclined state 27 in which it is accommodated in
the concave 22 and an erect state 28 in which it is erect.
-
These extension parts 25 and 25 of the handle 23 are so
configured that its turning is restricted as it comes into
contact, in its erect state 28, with a contact part 29
consisting of the upper edge of the concave 22, and the contact
part 29 is composed of an inclined face which inclined forward.
The handle 23 is so configured that, in this erect state 28,
its turning is restricted at a prescribed angle α beyond 90
degrees, more specifically 109 degrees from the inclined
state 27. By virtue of this arrangement, when the handle 23
in the inclined state 27 is to be shifted to the erect state
28, after the grip 24 constituting the free end of the handle
23 passes above the center of turning consisting of the
rotation shafts 26, the extension parts 25 and 25 stop in a
forward incline state in contact with the contact part 29.
-
On the moving path of the hose 14 wound up by the drum
15, the path being the front face 31 of the upper vessel 13,
a guide part 32 for guiding the hose 14 is disposed as shown
in FIG. 6. The guide part 32 is provided with an inlet/outlet
33 as an opening through which the hose 14 is inserted, and
the upper opening edge of the inlet/outlet 33 constitutes an
upper restrictive part 34 to prevent the hose 14 from escaping
upward. The upper restrictive part 34 extends in a direction
crossing the moving direction I of the hose 14 that is wound
up (see FIG. 1), and the upper restrictive part 34 is formed
in an arch shape, protruding upward in its central part.
-
Incidentally, although the guide part according to the
invention is configured by forming the inlet/outlet 33 in the
front face 31 in this embodiment, this guide part can as well
be formed by cutting a notch downward in the lower edge of
a plate-shaped member or configured of a pipe formed in an
angle or trapezoidal shape.
-
The upper restrictive part 34 is so set that the width
W of the lower side hose passage formed by the upper
restrictive part 34 is thereby set to become smaller toward
the upper part.
-
To add, though the example described above is a case in
which the upper restrictive part 34 is formed of the upper
opening edge of the inlet/outlet 33, this is not the only
possibility, but it may configured of a long member curbed
in an arch shape.
-
Also, the lower opening edge of the inlet/outlet 33 may
as well be open.
-
A bottom 35 is formed throughout the area of this upper
restrictive part 34 as shown in FIG. 5, and the bottom 35
protrudes outward from the body case 11. The position of the
upper restrictive part 34 in its highest area is set to be
lower than the highest area in the collars 18 of the drum 15
supported by the body case 11, and an allowance Y for hose
winding is set between the highest area in the upper
restrictive part 34 and the highest area in the collars 18.
-
The lower opening edge of the inlet/outlet 33, as shown
in FIG. 6, is linearly formed to constitute a lower
restrictive part 36 to allow the hose 14 to move in the lateral
direction. The inlet/outlet 33 is thereby formed in a
semicircular shape whose arch-shaped part is positioned at
the top.
-
The lower restrictive part 36 constituting the opening
edge of the inlet/outlet 33 is formed thicker than the general
part 37 as shown in FIG. 5 to constitute a thick part 38. This
thick part 38 is arch-shaped in sectional shape, protruding
toward the center of the inlet/outlet 33, and is so configured
that the hose 14 moving within the inlet/outlet 33 come into
line contact with it.
-
At the joints between the lower ends of the left and right
sides 41 and 42 of this upper vessel 13 and the upper ends
of the left and right sides 43 and 44 of the lower vessel 12,
there are formed bulgy parts 45 and 45 bulging sideways, which
constitute a circular form when joined together, as shown in
FIG. 1 and FIG. 6, and end parts of the barrel 17, protruding
from the collars 18 and 18 of the drum 15, are rotatably
supported between the bulgy parts 45 and 45 as shown in FIG.
3. Round holes 46 and 46 are provided at the centers of these
bulgy parts 45 and 45, and the shaft 48 of a crank-shaped handle
47 for turning the drum 15 is inserted into the round hole
46 of the bulgy part 45 arranged on the left side.
-
Also, a connecting plug 51 for connecting the faucet side
hose is inserted into the round hole 46 of the bulgy part 45
arranged on the right side, and one end of a pipe member 52
to be connected to the hose 14 wound around the drum 15 is
connected to the connecting plug 51. This configuration
enables running water from the faucet to be supplied to the
pipe member 52 via the connecting plug 51 and to the hose 14
on the sprinkling side, wound around the drum 15, via the pipe
member 52.
-
A rectangular bottom opening 62 is cut in the bottom 61
of the lower vessel 12 as shown in FIG. 7, and the body case
11 communicates with outside via this bottom opening 62.
-
Laterally long leg-fixing members 65 and 65 are screwed
on along the edges of the front and rear face sides of the
bottom 61. Cross-shaped shafts 66 and 66 protrude in mutually
opposite direction at the two ends of the leg fixing members
65 and 65 as shown in FIG. 8, and legs 67 and 67 formed in
the same shape are rotatably supported by the opposite shafts
66 and 66.
-
At both ends of these legs 67, cylindrical parts 71 and
71 to externally fit onto the shafts 66 and 66 are formed in
base ends 72, and top face parts 73 extending toward the tips
are integrally formed with these cylindrical parts 71. The
legs 67 and 67 are so configured as to be able to form as desired
by turning around the cylindrical parts 71 and 71 a folded
state 74 in which, as shown in FIG. 9, the tips of both legs
67 and 67 are arranged underneath the body case 11 and both
legs 67 and 67 are arranged underneath the bottom opening 62
or a developed state 75 in which, as shown in FIG. 1, the tips
of both legs 67 and 67 extend sideways from the body case 11
and are in contact with the bottom 61 of the body case 11 (see
FIG. 8) to be restricted in turning.
-
The configuration is such that the erect state of the
body case 11 can be thereby stabilized in the developed state
75 and, in the folded state 74, the bottom opening 62 cut in
the bottom 61 can be closed by the legs 67 and 67.
-
The top face parts 73 are formed in such lengths that,
when one leg 67 is folded ahead of the other leg 67 to
constitute the folded state 74 shown in FIG. 9, the parts of
the two legs 67 and 67 farther out than the base ends 72 and
72 overlap each other, and on their rear faces a plurality
of the ribs 81, ... and flanges 82 and 82 extending from their
two side edges are integrally formed. The heights of these
flanges 82 and 82 and the ribs 81, ... are set to become lower
from the base ends 72 toward the tips as shown in FIG. 8, and
the thickness of each leg 67 is set to become thinner from
the base ends 72 pivoting on the body case 11 toward the tip.
-
Further, the thickness of the legs 67 and 67 in their
overlapping parts 83, as shown in FIG. 9, is so set that the
sum of their thickness counts overlapping each other in the
folded state 74 be not greater than the greatest thickness
of the legs 67 and 67, i.e. at the base ends 72, resulting
in a configuration in which the legs 67 and 67 are positioned
above the under faces of the leg fixing members 65 in the folded
state 74.
-
And as shown in FIG. 5, two ribs 92 and 92 extend from
the bottom 61 toward the upper opening on an inner side face
91 of he lower vessel 12 of the body case 11, and two ribs
94 and 94 also extend from the top plate 21 toward the lower
opening on an inner side face 93 of the upper vessel 13 of
the body case 11. Thus, these ribs 92, 92, 94 and 94 extend
in the direction of mold drawing when the vessels 12 and 13
are molded of resin.
-
The heights H of the ribs 92, 92, 94 and 94, as shown
in FIG. 3, are set to be not less than the separation distance
R from each of the inner side faces 91 and 93 to the collars
18 of the drum 15, the lengths of the ribs 92, 92, 94 and 94,
as shown in FIG. 5, are so set as to bring their tips close
to the collars 18.
-
In this embodiment using the configuration described
above, when the hose 14 is to be wound up by turning the drum
15 with the handle 47, the hose 14 may sometimes concentrate
on one end of the drum 15, i. e. on the side of one of the collars
18. However, the guide part 32 for guiding the hose 14 is
disposed on the moving path of the hose 14, and the central
part of the upper restrictive part 34 set on the guide part
32 has an arch-shaped bulging upward. In other words, the
width W of the passage for the hose 14 formed underneath the
upper restrictive part 34 is so set as to decrease upward.
-
For this reason, when the hose 14 wound concentrating
around an end of the drum 15 reaches a prescribed height, the
hose 14 can be guided toward the central part along the upper
restrictive part 34 in the arch-shaped whose the width W
decreases upward.
-
Therefore, it is possible to prevent disorderly winding
of the hose 14, its concentration around one end of the drum
15 and to wind up the hose 14 neatly. This also contributes
to improve the appearance of the wound state of the hose and
to prevent deviation of the center of gravity.
-
On the other hand, at the time of starting winding of
the hose 14 around an empty drum 15, around which no hose 14
is wound yet, it is possible to guide this hose 14 along the
lower restrictive part 36 formed by the lower opening edge
of the inlet/outlet 33 in the guide part 32.
-
This lower restrictive part 36 here is linearly formed,
and allows the hose 14, guided in sliding contact with the
lower restrictive part 36, to move in the lateral direction
and the hose 14 to be wound around the whole area of the drum
15 in a distributed way. This enables disorderly winding at
the start of winding to be prevented.
-
And from the time a prescribed quantity of the hose 14
has been wound around the drum 15, the hose 14 can be guided
along the upper restrictive part 34 formed by the upper
opening edge of the inlet/outlet 33 in the guide part 32. The
above-described effect can be thereby achieved.
-
In this way, by bringing the hose 14 penetrating the
inlet/outlet 33 in sliding contact with opening edge of the
inlet/outlet 33, it can be guided to its prescribed position.
Therefore, compared with a case in which the hose 14 to be
wound around the drum 15 is not guided, disorderly winding
of the hose 14 can be prevented, with the result that the
appearance of the wound state of the hose can be improved and
deviation of the center of gravity due to disorderly winding
can be prevented.
-
In this configuration, the thick part 38 thicker than
the general part 37 is set for the lower restrictive part 36
constituting the opening edge of the inlet/outlet 33. For
this reason, inadvertent bending of the hose 14 can be more
securely prevented than in a case in which the opening edge
is composed of a thin part, resulting in improved ease of
winding.
-
Furthermore, the section of the thick part 38 of the lower
restrictive part 36 is formed in an arc shape, protruding
toward the center of the inlet/outlet 33. As a result, its
area of sliding contact with the hose 14 can be reduced, making
it possible to restrain the frictional resistance that arises
at the time of winding. Therefore, the winding of the hose
14 can be facilitated.
(Second Embodiment)
-
FIG. 10 shows a second embodiment, wherein parts having
exact or equivalent counterparts in the above-described
embodiment are denoted by respectively the same signs, their
description being dispensed with.
-
Thus, a roller 101 as a columnar rotational member is
disposed on the lower opening edge of the linearly formed
inlet/outlet 33. The shaft 102 extending from the two ends
of this roller 101 is rotatably supported by the bottom 35,
with its ends inserted into the two lower ends of the bottom,
and is so configured as to rotate in the direction of urging
the movement of the hose 14 when it comes into contact with
the hose 14 moving through the inlet/outlet 33.
-
This enables the hose 14 wound up by the drum 15 to come
into contact with the roller 101 disposed on the moving path
of the hose 14. This roller 101 then comes into contact with
the hose 14 and rotates in the direction of urging the movement
of the hose 14. The roller 101 is thereby enabled to guide
the hose 14 to the drum 15.
-
Therefore, compared with a case in which the hose 14 to
be wound up by the drum 15 is not guided, disorderly winding
of the hose 14 can be better prevented and the hose 14 can
be wound more neatly. Also, the appearance of the wound state
of the hose can be improved, and deviation of the center of
gravity due to disorderly winding can be prevented.
-
In this configuration, the roller 101 rotates in the
direction of urging the movement of the hose 14. The
resistance of the hose 14 to frictional contact with the
roller 101 can be thereby restrained, and the winding of the
hose 14 can be facilitated.
-
Incidentally, though this embodiment has been described
with reference to a case in which the roller 101 is disposed
on the lower opening edge of the inlet/outlet 33, the choice
is not limited to this, but some other rolling members such
as another type of roller could give the same effect as
described above.
(Third Embodiment)
-
A third embodiment of the invention will be described
below with reference to drawings. FIG. 11 is a drawing
showing a hose reel 201 in this embodiment, and the hose reel
201 is used for winding up a hose 202 for sprinkling use.
-
The frame 212 of this hose reel 201 is provided with
disk-shaped sides 213 and legs 214 and 214 disposed between
the two sides 213. Between the two sides 213, a drum 215 for
winding up the hose 202 is rotatably supported. The base ends
of a handle 216 formed by bending a pipe in an angular C shape
is fixed to the two sides 213, and the hose reel 201 is so
configured that it can be carried by this handle 216.
-
The ends of a guide bar 221 as the guide part for the
hose 202 to be wound up by the drum 215 is fixed to the two
sides 213, and the guide bar 221 is formed by bending a pipe
in a U shape. This guide bar 221 and the handle 216 are linked
by a linking bar 222 to maintain the angle of inclination of
the guide bar 221 relative to the handle 216.
-
The tip of this guide bar 221 is disposed on the moving
path of the hose 202 to be wound up by the drum 215, extends
in a direction crossing the moving direction of the hose 202
to be wound up, and constitutes a restrictive part 231 to
prevent the hose 202 from escaping. And this restrictive part
231 is formed in an arc shape whose central part protrudes.
-
The drum 215 is configured of a cylindrical barrel 241
around which the hose 202 is wound and collars 242 disposed
at the two ends of the barrel 241, and its ends are rotatably
supported in a state of being held between the two sides 213
of the frame 212.
-
On the other hand, the hose 202 is configured of an inner
annular member 251 disposed inside and an outer annular member
252 disposed outside the inner annular member 251 as shown
in FIG. 12, and a braid 255 consisting of a net portion 253
knit of threads crossing each other diagonally and warps
254, ... extending in the lengthwise direction are disposed
on the outer circumferential face of the inner annular member
251. The net portion 253 is configured of first bias threads
256, ... and second bias threads 257, ... crossing each other.
-
On the outer circumferential face 261 of the outer
annular member 252, convex stripes 262, ... and concave
grooves 263, ..., both extending in the lengthwise direction,
are alternately formed to constitute striped convexes and
concaves extending in the lengthwise direction.
-
Incidentally, the method of forming convexes and
concaves in the outer circumferential face 261 is not limited
to this, but the configuration may as well consist of
point-shaped convexes for instance.
-
Further, this hose 202 is supposed to be used in all the
modes for implementation including the foregoing and those
to be described afterwards.
-
In this embodiment pertaining to the above-described
configuration, when the hose 202 is wound up by turning the
drum 215 with the handle 47, the hose 202 may sometimes
concentrate on one end of the drum 215, i.e. on the side of
one of the collars 242. However, the guide bar 221 for guiding
the hose 202 is disposed on the moving path of the hose 202,
and the central part of the restrictive part 231 disposed on
the guide bar 221 has an arch-shaped protruding upward.
-
For this reason, when the hose 202 wound concentrating
around an end of the drum 215 reaches a prescribed height,
the hose 202 can be guided along the restrictive part 231 in
the arch-shaped toward the center.
-
Therefore, disorderly winding of the hose 202
concentrating on one end of the drum 215 can be prevented,
and the hose 202 can be wound up neatly. Also, the appearance
of the wound state of the hose can be improved, and deviation
of the center of gravity can be prevented.
-
And when the hose is wound, the outer circumferential
face 261 comes into contact with the inner face of the drum
215 or that of the frame 212 and may give rise to friction.
However, as the outer circumferential face 261 of this hose
202 is made rugged in a striped shape by the convex stripes
262, ... and the concave grooves 263, ... both extending in
the lengthwise direction, the frictional resistance to the
area of sliding contact can be reduced.
-
Disorderly winding of the hose 202 around the drum 215
can be thereby better prevented than in a case in which high
frictional resistance occurs to the area of sliding contact
with the hose 202.
-
Also, the hose 202 can be smoothly wound round the drum
215, the operational power required for turning the drum 215
can be reduced, and at the same time the winding work can be
facilitated.
-
Incidentally, though this embodiment has been described
with reference to a case in which the guide bar 221 bridging
the sides 213 of the frame 212 is configured of a pipe formed
in a U shape, the configuration is not limited to this, but
the guide part for guiding the hose 202 to be wound up by the
drum 215 may instead be formed of, for instance, a wire rod,
wire, pipe or plastic.
-
Further, though this embodiment has been described with
reference to a case in which the guide bar 221 and the handle
216 are linked by the linking bar 222, the configuration is
not limited to this, but the linking bar 222 can be dispensed
with.
(Fourth Embodiment)
-
FIG. 13 shows a fourth embodiment, wherein parts having
exact or equivalent counterparts in the third embodiment are
denoted by respectively the same signs, their description
being dispensed with.
-
Thus, this hose reel 301 also is of a type in which the
drum 215 is exposed, and the frame 212 of the hose reel 301
is formed by bending a single pipe member. A C-shaped leg
214 is formed in the lower part of the frame 212, and erect
portions 302 and 302 stand at the two ends of the leg 214.
Turned-up portions 303 and 303, turned upward over the leg
214, are formed continuing from the erect portions 302 and
302, and supporting portions 304 and 304 rotatably supporting
the drum 215 are disposed in the middle parts of the turned-up
portions 303 and 303.
-
The tips of the two turned-up portions 303 and 303 are
linked to the guide part 311, and the restrictive part 231
disposed on the moving path of the hose to be wound up by the
drum 215 and extending in a direction crossing the moving
direction of the hose to be wound up to prevent the hose from
escaping is set on the guide part 311. And this restrictive
part 231 is formed in an arc shape whose central part
protrudes.
-
This embodiment can give the same effect as the third
embodiment.
-
In addition, since the frame 212 can be configured of
a single pipe member, the configuration can be simplified and
the cost reduced.
-
Incidentally, though the third and fourth modes for
implementation has been described with reference to cases in
which the restrictive part 231 is formed in a U shape, the
configuration is not limited to this.
(Fifth Embodiment)
-
Thus, as shown in FIG. 14A, this configuration may be
formed of vertical portions 401 and 401 linearly extending
upward from the tips of the two turned-up portions 303 and
303, linear inclined portions 402 and 402 extending inward
with an inclination from the tips of the vertical portions
401 and 401, and a linear linking portion 403 linking the two
inclined portions 402 and 402.
(Sixth Embodiment)
-
Also, as shown in FIG. 14B, the base ends of the two
vertical portions 401 and 401 may be linked by a linear lateral
portion 411 to constitute a lower restrictive part.
(Seventh Embodiment)
-
Further, as shown in FIG. 14C, with the vertical portions
401 and 401 being abolished, the inclined portions 402 and
402 may be directly linked to the turned-up portions 303 and
303 to configure a trapezoidal restrictive part 231.
(Eighth Embodiment)
-
FIG. 15 shows an eighth embodiment, wherein parts having
exact or equivalent counterparts in the first embodiment
described above are denoted by respectively the same signs,
their description being dispensed with.
-
Thus, on the moving path of the hose 14 to be wound up
by the drum 15, which is the front face 31 of the upper vessel
13 constituting part of the body case 11, the guide part 32
for guiding the hose 14 is set. The guide part 32 is provided
with the inlet/outlet 33 as the opening through which the hose
14 is to be inserted, and the upper opening edge of the
inlet/outlet 33 constitutes the upper restrictive part 34
which obstructs upward escaping of the hose 14. The upper
restrictive part 34 extends in a direction crossing the moving
direction I of the hose 14 to be wound up (see FIG. 1), and
the upper restrictive part 34 is formed in an angle or
trapezoidal shape whose central part protrudes upward.
-
This upper restrictive part 34 is linked to the two ends
of the lower restrictive part 36 which the lower edge of the
inlet/outlet 33 constitutes, and is configured of inclined
parts 501 and 501 inclined toward the central part of the
inlet/outlet 33 as they extend upward and a horizontal portion
502 linking the upper ends of the two inclined parts 501; the
inclination angle β between the horizontally extending lower
restrictive part 36 and the inclined parts 501 and 501 is set
in a range of not less than 45 degrees and less than 90 degrees.
-
When the hose 14 is wound by turning the drum 15 in the
configuration described above, the hose 14 may sometimes
concentrate on one end of the drum 15. However, the guide
part 32 for guiding the hose 14 is provided on the moving path
of the hose 14, and the inclined parts 501 and 501 inclined
toward the central part as they extend upward are set on the
upper restrictive part 34 set on the guide part 32.
-
As a result, the hose 14 wound concentrating on the end
of the drum 15 can be guided toward the center of the
inlet/outlet 33 by the inclined parts 501 and 501 when a
prescribed quantity has been wound up.
-
Therefore, disorderly winding of the hose 14
concentrating on one end of the drum 15 can be prevented, and
the hose 14 can be wound up neatly. Also, the appearance of
the wound state of the hose can be improved, and deviation
of the center of gravity due to disorderly winding can be
prevented.
-
Although a vertical component of force F1 and a
horizontal component of force F2 then work on the hose 14 in
contact with these inclined parts 501 and 501, but the
inclination angle β of the inclined parts 501 is set to be
not less than 45 degrees and less than 90 degrees. As a result,
the horizontal component of force F2 is not less than the
vertical component of force F1, and the force of guiding the
hose 14 wound up in the prescribed quantity toward the central
part can be kept not less than the force pressing the hose
14 downward.
-
For this reason, it is possible to prevent the hose 14
wound up in the prescribed quantity from being squeezed in
a state of being pressed down from above.
(Ninth Embodiment)
-
FIG. 16 shows a hose reel 601 in the ninth embodiment;
the hose reel 601 is used for winding up a hose for sprinkling
use.
-
This hose reel 601 is provided with a rectangular body
case 611 constituting a frame, and the width C1 of the body
case 611 is set to 220 mm. The length C2 of the body case
611 is set to 375 mm and its height C3, to 394.8 mm.
-
This body case 611, as shown in FIG. 17, is formed by
a lower vessel 612 as the upward open lower constituent member
of an rectangular container and an upper vessel 613, which
is the downward open upper constituent member of the
rectangular container, coupled with tapping screws not shown.
The internal space K of this body case 611 accommodates a drum
615 around which a hose 614 of 16.4 mm in diameter HD is to
be wound as shown in FIG. 18.
-
The hose 614 is set to be 2.2 mm in thickness HT and to
12 mm in inner diameter HI. Further, a plurality of convex
stripes 620, ... extending in the lengthwise direction are
formed over the whole length of the outer circumferential
face.
-
The drum 615 is configured of a cylindrical barrel 617
around which the hose 614 having penetrated a hose insertion
hole 616 is wound and collars 618 and 618 disposed at the two
ends of the barrel 617, and the winding position 619 of the
hose 614 is set between the two collars 618 and 618.
-
This drum 615 is set to a capacity sufficient for winding
the hose 614 of 25 m. The length of the hose 614 to be wound
up by this drum 615 is set to 80% of it, i.e. 20 m. It is
thus designed to be able to wind up the hose 614 at a lower
material cost than where a drum of a larger diameter is used.
Further by keeping the height C3 lower, the body case 611 which
would not easily fall down is realized.
-
To add, it is desirable for the length of the hose 614
to be wound around the drum 615 to be not greater than 80%
of what the drum 615 can accommodate.
-
More specifically, the diameter DD of the collars 618
and 618 is set to 280 mm and the distance H2 between the two
collars 618 and 618, to 144 mm (see FIG. 22). Thus, the
distance H2 between the two collars 618 and 618 is set to be
40% to 60% of the diameter DD of the collars 618 and 618, i.e.
between 112 mm and 168 mm.
-
While the winding ease of the hose 614 can be enhanced
by reducing the distance H2 between the collars 618 and 618
of the drum 615 herein, too short a distance H2 between the
collars 618 and 618 would make the drum 615 thin and apt to
easily fall down. In view of this factor, repeated
experiments have led to a discovery that the two requirements
can be made consistent with each other by setting the distance
H2 between the collars 618 and 618 of the drum 615 to between
40% and 60% of the diameter DD of the collars 618 and 618.
For this reason, in this embodiment, the distance H2 between
the collars 618 and 618 of the drum 615 is set to 144 mm, which
lies between 40% and 60% of the diameter DD of the collars
618 and 618.
-
Incidentally as another variation, there is made
available a configuration in which the distance H2 between
the collars 618 and 618 of this drum 615 is set to 171 mm and
the diameter DD of the collars 618 and 618, to 340 mm, i.e.
the distance H2 between the collars 618 and 618 is set between
40% and 60% of the diameter DD of the collars 618 and 618.
In this drum 615, the accommodable length of the hose 614 is
38 m, and the length of the hose 614 to be wound around the
drum 615 is set to be 30 m, not more than 80% of that
accommodable length.
-
The top plate 621 of the upper vessel 613 is formed
rectangular and flat as shown in FIG. 16 and FIG. 20. The
top plate 621, set to be large enough to permit the mounting
of the body case 611 of another hose reel, constitutes a load
carrier.
-
A C-shaped concave 622 is formed in this top plate 621,
and a C-shaped handle 623 is arranged in the concave 622. The
handle 623 is composed of a grip 624 constituting a free end
and extension parts 625 and 625 extending from the two ends
of the grip 264 into the C shape, and turnably supported by
the upper vessel 613 via rotation shafts 626 and 626 disposed
at the tips of the extension parts 625 and 625 as shown in
FIG. 21. In this way, the handle 623 is so configured as to
be turnable between an inclined state 627 in which it is
accommodated in the concave 622 and an erect state 628 in which
it is erect.
-
These extension parts 625 and 625 of the handle 623 are
so configured that its turning is restricted as it comes into
contact, in its erect state 628, with a contact part 629
consisting of the upper edge of the concave 622, and the
contact part 629 is composed of an inclined face which is
inclined forward. The handle 623 is so configured that, in
this erect state 628, its turning is restricted at a
prescribed angle 6α beyond 90 degrees, more specifically 109
degrees from the inclined state 627. By virtue of this
arrangement, when the handle 623 in the inclined state 627
is to be shifted to the erect state 628, after the grip 624
constituting the free end of the handle 623 passes above the
center of turning consisting of the rotation shafts 626, the
extension parts 625 and 625 stop in a forward inclined state
in contact with the contact part 629.
-
On the moving path of the hose 614 wound up by the drum
615, the path being the front face 631 of the upper vessel
613, a guide part 632 for guiding the hose 614 is disposed
as shown in FIG. 22. The guide part 632 is provided with an
inlet/outlet 633 as an opening through which the hose 614 is
inserted, and the inlet/outlet 633 is disposed in the position
opposite the winding position 619 set between the two collars
618 and 618 of the drum 615.
-
The width H1 of the inlet/outlet 633 is set to be not
greater than the distance H2 from one of the collars 618 of
the drum 615 to the other collar 618. More specifically, the
width H1 at the lower end of the inlet/outlet 633, its greatest
width, is set between 134 mm and 154 mm, preferably should
be set not greater than 144 mm, the distance H2 between the
two collars 618 and 618 of the drum 615, and in this embodiment
it is set to be less than 144 mm. The height H3 of the
inlet/outlet 633 in the central part, its greatest height is
set to be 100 mm.
-
Incidentally, though the width H1 of the inlet/outlet
633 is set to be less than the distance H2 between the two
collars 618 and 618 of the drum 615 in this embodiment, the
two dimensions may as well be the same.
-
To add, the relationship between the width H1 of the
inlet/outlet 633 and the distance H2 between the two collars
618 and 618 is not limited to this, but the width H1 may as
well be not greater than the distance H2, preferably not less
than 2/3 of the distance H2.
-
The upper opening edge of this inlet/outlet 633
constitutes an upper restrictive part 634 for obstructing the
hose 614 from escaping upward. The upper restrictive part
634 extends in a direction crossing the moving direction 6I
of the hose 614 that is wound up (see FIG. 1), and the upper
restrictive part 634 is formed in an arc shape whose central
part protrudes upward.
-
The starting point S of the arc shape of the opening edge
of the inlet/outlet 633 is set in the position of the height
of the lower edge of the inlet/outlet 633 and between the
center of rotation DC of the drum 615 and the highest position
DS of the collars 618 and 618. As a result, the width H1 of
the inlet/outlet 633 decreases from the lower edge upward.
-
Incidentally, though the foregoing description referred
to a case in which the upper restrictive part 634 is formed
by the upper opening edge of the inlet/outlet 633, but the
configuration is not limited to this, but it may as well
consist of a long member curved in an arc shape for instance.
-
Also the lower opening edge of the inlet/outlet 633 may
be open.
-
A lean-to cover 635 is formed over the whole area of this
upper restrictive part 634 as shown in FIG. 21, and the lean-to
cover 635 protrudes toward outside the body case 611. The
height of the upper restrictive part 634 in its highest
position is set to be lower than the highest positions of the
collars 618 of the drum 615 supported by the body case 611,
and an allowance 6Y for winding up the hose is provided between
the highest position of the upper restrictive part 634 and
the highest positions of the collars 618.
-
The lower opening edge of the inlet/outlet 633 is
linearly formed as shown in FIG. 22, and a lower restrictive
part 636 to allow the hose 614 to move in the horizontal
direction is formed on the moving path of the hose 614. This
causes the inlet/outlet 633 to be formed in a semicircular
shape whose arch-shaped part is positioned at the top.
-
The lower restrictive part 636 constituting the opening
edge of the inlet/outlet 633 is formed thicker than the
general part 637 and constitutes a thick part 638 as shown
in FIG. 21. The sectional shape of this thick part 638 is
formed in an arc shape protruding toward the center of the
inlet/outlet 633, and the configuration is such that the hose
614 moving through the inlet/outlet 633 comes into line
contact.
-
At the joints between the lower ends of the left and right
sides 641 and 642 of this upper vessel 613 and the upper ends
of the left and right sides 643 and 644 of the lower vessel
612, there are formed bulgy parts 645 and 645 bulging sideways,
which constitute a circular form when joined together, as
shown in FIG. 16 and FIG. 22, and end parts of the barrel 617,
protruding from the collars 618 and 618 of the drum 615, are
rotatably supported between the bulgy parts 645 and 645 as
shown in FIG. 18. Round holes 646 and 646 are provided at
the centers of these bulgy parts 645 and 645, and the shaft
648 of a crank-shaped handle 647 for turning the drum 615 is
inserted into the round hole 646 of the bulgy part 645 arranged
on the left side.
-
Also, a connecting plug 651 for connecting the faucet
side hose is inserted into the round hole 646 of the bulgy
part 645 arranged on the right side, and one end of a pipe
member 652 to be connected to the hose 614 wound around the
drum 615 is connected to the connecting plug 651. This
configuration enables running water from the faucet to the
pipe member 652 via the connecting plug 651 and to the hose
614 on the sprinkling side, wound around the drum 615, via
the pipe member 652.
-
On the left and right sides 641, 642, 643 and 644 of the
upper and lower vessels 612 and 613 on which the bulgy parts
645 and 645 are formed, hoop- like parts 655 and 655 extending
upward and downward are disposed in the upper and lower
positions of the bulgy parts 645 and 645, which are the
positions of supporting the drum 615, as shown in FIG. 16.
These hoop- like parts 655 and 655 are formed in a corrugated
shape by alternately arranged a plurality of convex stripes
656, ... and concave grooves 657, ..., both extending upward
and downward. These hoop- like parts 655 and 655 are thereby
configured to reinforce the planar left and right sides 641,
642, 643 and 644 and to function as props to support the drum
615.
-
A rectangular bottom opening 662 is cut in the bottom
661 of the lower vessel 612 as shown in FIG. 23, and the body
case 611 communicates with outside via this bottom opening
662.
-
Laterally long leg-fixing members 665 and 665 are screwed
on along the edges of the front face side 631 and the rear
face side 668 of the bottom 661. Cross-shaped shafts 666 and
666 protrude in mutually opposite directions at the two ends
of the leg fixing members 665 and 665 as shown in FIG. 24,
and legs 667 and 667 formed in the same shape are rotatably
supported by the opposite shafts 666 and 666.
-
At both ends of these legs 667, cylindrical parts 671
and 671 to externally fit onto the shafts 666 and 666 to
constitute base ends 672, and top plate parts 673 extending
toward the tips are integrally formed with these cylindrical
parts 671. The legs 667 and 667 are so configured as to be
able to form as desired by turning around the cylindrical
parts 671 and 671 a folded state 674 in which, as shown in
FIG. 25, the tips of both legs 667 and 667 are arranged
underneath the body case 611 and both legs 667 and 667 are
arranged underneath the bottom opening 662 or a developed
state 675 in which, as shown in FIG. 16, the tips of both legs
667 and 667 extend sideways from the body case 611 and are
in contact with the bottom 661 of the body case 611 (see FIG.
24) to be restricted in turning.
-
The configuration is such that the erect state of the
body case 611 can be thereby stabilized in the developed state
675 and, in the folded state 674, the bottom opening 662 cut
in the bottom 661 can be closed by the legs 667 and 667.
-
The top plate parts 673 are formed in such lengths that,
when one leg 667 is folded ahead of the other leg 667 to
constitute the folded state 674 shown in FIG. 26, the parts
of the two legs 667 and 667 farther out than the base ends
672 and 672 overlap each other on their tip side, and on their
rear faces a plurality of the ribs 681, ... and flanges 682
and 682 extending from their two side edges are integrally
formed. The heights of these flanges 682 and 682 and the ribs
681, ... are set to become lower from the base ends 672 toward
the tips as shown in FIG. 24, and the thickness of each leg
667 is set to become thinner from the base ends 672 pivoting
on the body case 611 toward the tip.
-
Further, the thickness of the legs 667 and 667 in their
overlapping parts 683, as shown in FIG. 25, is so set that
the sum of their thickness counts overlapping each other in
the folded state 674 be not greater than the greatest
thickness of the legs 667 and 667, i.e. at the base ends 672,
resulting in a configuration in which the legs 667 and 667
are positioned above the under faces of the leg fixing members
665 in the folded state 674.
-
And as shown in FIG. 21, two ribs 692 and 692 extend from
the bottom 661 toward the upper opening on an inner side face
691 of the lower vessel 612 of the body case 611, and two ribs
694 and 694 also extend from the top plate 621 toward the lower
opening on an inner side face 693 of the upper vessel 613 of
the body case 611. Thus, these ribs 692, 692, 694 and 694
extend in the direction of mold drawing when the vessels 612
and 613 are molded of resin.
-
The height 6H of the ribs 692, 962, 694 and 694, as shown
in FIG. 18, is set to be not less than the separation distance
6R from each of the inner side faces 691 and 693 to the collars
618 of the drum 615, the lengths of the ribs 692, 692, 694
and 694, as shown in FIG. 21, are so set as to bring their
tips close to the collars 618.
-
In this embodiment pertaining to the configuration
described above, the body case 611 as a frame for rotatably
supporting the drum 615 of the hose reel 601 is formed in a
case shape allowing accommodation of the drum 615, the
inlet/outlet 633 for the hose 614 is disposed in the position
in the body case 611 opposite the winding position 619 between
the two collars 618 and 618 of the drum 615, and the hose 614
wound up by the drum 615 moves via this inlet/outlet 633.
-
And the width H1 of this inlet/outlet 633 is set to be
not greater than the distance H2 from one collar 618 of the
drum 615 to the other collar 618. As a result, the hose 614
accommodated into the body case 611 via the inlet/outlet 633
can be guided to the position between the two collars 618 and
618 of the drum 615.
-
Therefore, compared with the conventional case in which
the winding direction of the hose 614 is open and the hose
614 is apt to be wound into the gap between the drum 615 and
the frame, the winding of the hose 614 into the gap between
the drum 615 and the inner face of the body case 611 can be
prevented, and the hose 614 can be wound up neatly.
-
Especially, where the body case 611 is formed in a case
shape and the hose 614, if wound into the gap between the drum
615 and the body case 611, will be difficult to take out as
in this embodiment, any problem due to the winding-in can be
prevented from arising.
-
Further, the distance H2 between the two collars 618 and
618 provided at the two ends of the barrel 617 of the drum
615 around which the hose 614 is to be wound is set between
40% and 60% of the diameter DD of the collars 618 and 618;
when the hose 614 is wound around such a drum 615, even if
the hose 614 is wound concentrating on one of the collars 618,
a collapse will arise within. For this reason, the hose 614
is guided to a position between the two collars 618 and 618
by being wound around this drum 615. This can prevent the
hose 614 from inadvertently coming off the drum 615.
-
Therefore, compared with the conventional case in which
the hose is apt to be wound into the gap between the drum and
the frame, the winding of the hose 614 into the gap between
the drum 615 and the inner face of the body case 611 can be
prevented, and the hose 614 can be wound up neatly. Further,
as the hose 614 wound concentrating on one of the collars 618
can be collapsed inward, it can be stabilized at the time of
winding.
-
And the setting of the distance H2 between the collars
618 and 618 of the drum 615 between 40% and 60% of the diameter
DD of the collars 618 and 618 facilitates winding of the hose
614 and can make the hose reel 601 difficult to fall down.
-
And when the hose 614 is wound up by the drum 615, the
hose 614 may sometimes concentrate on the collar 618 at one
end of the drum 615. However, the upper opening edge of the
inlet/outlet 633 through which the hose 614 moves is set to
have a width H which becomes narrower upward, and is formed
in an arc shape whose central part protrudes upward.
-
For this reason, the hose 614 wound concentrating on one
end of the drum 615, when wound up to a prescribed quantity,
is guided toward the center along the arch-shaped opening
edge.
-
Thus, even when the hose 614 is concentrating on the
collar 618 at one end of the drum 615, the hose can be guided
toward the center along the arch-shaped opening edge at the
time it has been wound up to the prescribed quantity. This
can prevent disorderly winding, i.e. winding of the hose 614
concentrating on one end of the drum 615, and the wound state
of the hose 614 can be evened up. Therefore, deviation of
the center of gravity due to disorderly winding can be
prevented.
-
Furthermore, the starting point S of the arc shape of
the opening edge of the inlet/outlet 633 is set between the
center of rotation DC of the drum 615 and the highest position
DS of the collars 618 and 618. As a result, the hose 614 wound
concentrating on the collar 618 at one end of the drum 615
can be guided toward the center along the arch-shaped opening
edge before it reaches the highest position DS of the collars
618 and 618.
-
Incidentally, though the foregoing description referred
to a case in which the starting point S of the arc shape of
the opening edge is set on the lower edge of the inlet/outlet
633, but the configuration is not limited to this, but a linear
portion 6101 rising from the lower edge of the inlet/outlet
633 may be disposed and an arch portion 6102 in an arch shape
formed from its upper end as shown in FIG. 26.
-
In this case, the starting point S on the border between
the linear portion 6101 and the arch portion 6102 is set
between the center of rotation DC of the drum 615 and the
highest position DS of the collars 618 and 618.
-
Nor is the inlet/outlet 633 is limited to the above-described
shape, but may as well be semicircular as shown in
FIG. 27A or triangular as in FIG. 27B.
-
Further, where the inlet/outlet 633 is to be triangularly
shaped, its two upper sides 6111 and 6111 may be rounded, bent
toward the center of the opening, as shown in FIG. 28A, and
the range of rounding could be set between 100R and 300R for
example.
-
In addition, where the inlet/outlet 633 is to be
triangularly shaped, its two upper sides 6121, 6121 may be
rounded, bent outward from the center of the opening, as shown
in FIG. 28B, and the range of rounding could be set between
100R and 300R for example.
Industrial Applicability
-
As hitherto described, the hose reel according to Claim
1 of the present invention, even when the hose is wound
concentrating on one end of the drum, it can be guided along
the guide part, whose width decreases toward its upper portion,
toward the central part when a prescribed quantity has been
wound up.
-
Therefore, disorderly winding of the hose concentrating
on one end of the drum can be prevented, and the hose can be
wound neatly. Also, the appearance of the wound state of the
hose can be improved and deviation of the center of gravity
due to disorderly winding can be prevented.
-
Also the hose reel according to Claim 2 of the invention,
even when the hose is wound concentrating on one end of the
drum, it can be guided by an inclined part provided in the
restrictive part toward the central part when a prescribed
quantity has been wound up.
-
Therefore, disorderly winding of the hose concentrating
on one end of the drum can be prevented, and the hose can be
wound neatly. Also, the appearance of the wound state of the
hose can be improved and deviation of the center of gravity
due to disorderly winding can be prevented.
-
Then, a downward component of force and a horizontal
component of force arise in the hose that has come into contact
with this inclined part, and the angle of inclination of the
inclined part is set to be not less than 45 degrees and less
than 90 degrees. For this reason, the horizontal component
of force is not less than the downward component of force,
and the force guiding the hose stacked to a prescribed
quantity toward the central part is not less than the force
pressing the hose downward.
-
Therefore, it is possible to prevent the hose wound up
in the prescribed quantity from being squeezed in a state of
being pressed down from above.
-
Further, the hose reel according to Claim 3 of the
invention, even when the hose is wound concentrating on one
end of the drum, it can be guided along an arch-shaped
restrictive part toward the central part when a prescribed
quantity has been wound up.
-
Therefore, disorderly winding of the hose concentrating
on one end of the drum can be prevented, and the hose can be
wound neatly. Also, the appearance of the wound state of the
hose can be improved and deviation of the center of gravity
due to disorderly winding can be prevented.
-
Or in the hose reel according to Claim 4 of the invention,
when starting winding of the hose around an empty drum, the
hose to be moved can be guided along the lower opening edge
of the opening in the guide part. In this arrangement this
lower opening edge is linearly formed. As a result, the hose
guided by the guide part can be wound around the whole area
of the drum in a distributed way, and disorderly winding at
the time of starting the winding can be prevented.
-
And when a prescribed quantity of the hose has been wound
up around the drum, it is guided along the restrictive part
formed by the upper opening edge of the opening in the guide
part. This provides a similar effect to what was described
above.
-
Further in the hose reel according to Claim 5 of the
invention, the drum is supported by the frame, and the guide
part can be configured by providing this frame with a bar.
This contributes to simplifying the configuration.
-
In addition, in the hose reel according to Claim 6 of
the invention, by inserting the hose to be wound up by the
drum into the opening of the guide part, the hose can be brought
into sliding contact with the opening edge of the opening and
thereby guided to its prescribed position.
-
Therefore, compared with a case in which the hose to be
wound up by the drum is not guided, disorderly winding of the
hose can be better prevented and the hose can be wound more
neatly. Also, the appearance of the wound state of the hose
can be improved, and deviation of the center of gravity due
to disorderly winding can be prevented.
-
In this configuration, the thick part thicker than the
general part is set for the opening edge of the opening. For
this reason, inadvertent bending of the hose can be more
securely prevented than in a case in which the opening edge
is composed of a thin part, resulting in improved ease of
winding.
-
Moreover, in the hose reel according to Claim 7 of the
invention, by inserting the hose to be wound up by the drum
into the opening of the guide part, the hose can be brought
into sliding contact with the opening edge of the opening and
thereby guided to its prescribed position.
-
Therefore, compared with a case in which the hose to be
wound up by the drum is not guided, disorderly winding of the
hose can be better prevented and the hose can be wound more
neatly. Also, the appearance of the wound state of the hose
can be improved, and deviation of the center of gravity due
to disorderly winding can be prevented.
-
In this configuration, the opening edge of the opening
is formed in a sectional shape of an arc shape protruding
toward the center of the opening. As a result, the area of
contact with the hose in sliding contact can be reduced, and
the frictional resistance occurring at the time of winding
can be restrained. Therefore, the winding of the hose can
be facilitated.
-
Further in the hose reel according to Claim 8 of the
invention, the hose to be wound up by the drum can be guided
by the rotational member rotating in contact with the hose.
-
Therefore, compared with a case in which the hose to be
wound up by the drum is not guided, disorderly winding of the
hose can be better prevented and the hose can be wound more
neatly. Also, the appearance of the wound state of the hose
can be improved, and deviation of the center of gravity due
to disorderly winding can be prevented.
-
In this configuration, the roller rotates in the
direction of urging the movement of the hose. Accordingly,
the resistance of the hose to frictional contact with the
roller can be thereby restrained, and the winding of the hose
can be facilitated.
-
And in the hose reel according to Claim 9 of the invention,
the frictional resistance between the outer circumferential
face and the area of sliding contact can be reduced by making
the outer circumferential face of the hose rugged. Compared
with a case in which a high frictional resistance occurs in
the area of sliding contact with the hose, disorderly winding
of the hose around the drum can be better prevented.
-
The winding of the hose around the drum is further
smoothened, the operational power required for turning the
drum can be reduced, and at the same time the winding work
can be facilitated.
-
Moreover, in the hose reel according to Claim 10 of the
invention, the width of the inlet/outlet provided in the frame
is set to be not greater than the distance from one collar
of the drum to the other, and the hose accommodated into the
frame via the inlet/outlet can be guided to the position
between the two collars of the drum.
-
Therefore, compared with the conventional case in which
the winding direction of the hose is open and the hose is apt
to be wound into the gap between the drum and the frame, the
winding of the hose into the gap between the drum and the inner
face of the body case can be prevented, and the hose can be
wound up neatly.
-
Especially, where the frame is formed in a case shape
as in the hose reel according to Claim 11, if the hose is wound
into the gap between the drum and the frame and is difficult
to take out, any problem due to the winding-in can be prevented
from arising.
-
Moreover, in the hose reels according to Claims 12 and
13, even if the hose is wound concentrating on one end of the
drum, it can be guided along the opening edge of the
inlet/outlet or the arch-shaped opening edge toward the
center when a prescribed quantity has been wound up.
-
This can prevent disorderly winding, i. e. winding of the
hose concentrating on one end of the drum, and enable the wound
state of the hose to be evened up.
-
Therefore, deviation of the center of gravity due to
disorderly winding can be prevented, and the quantity of hose
set at the time of designing can be wound around the drum.
-
Further in the hose reel according to Claim 14, as the
starting point of the arc shape of the opening edge is set
between the center of rotation of the drum and the highest
position of the collars, the hose concentrating on the collar
at one end of the drum can be guided toward the center along
the arch-shaped opening edge before it reaches the highest
position of the collars.
-
Moreover, in the hose reel according to Claim 15, as the
distance between the collars of the drum is set between 40%
and 60% of the diameter of the collars, the hose wound around
this drum can be guided between the collars. Therefore any
trouble due to the going astray of the hose from the drum can
be prevented, resulting in neat winding of the hose.
-
Also, as the hose wound concentrating on one of the
collars can be collapsed inward, it can be stabilized at the
time of winding. And the setting of the distance between the
collars of the drum between 40% and 60% of the diameter of
the collars facilitates winding of the hose and can make the
hose reel difficult to fall down.
