GARDENING FLUID CONNECTION DEVICE
TECHNICAL FIELD
100011 The present disclosure relates to a gardening fluid connection device
which is
employed to connect with a water spray gun, a sprinkler or a water hose.
BACKGROUND
[0002] A conventional gardening fluid connection device, such as disclosed in
TW
Patent Nos. 260238, 532442, 1319072 and US Patent No. 7021669, is employed to
connect with
a water supply device (e.g., a water spray gun, a sprinkler, or a water hose).
The conventional
gardening fluid connection device contains a fitting sleeve reciprocatingly
rotated leftward or
rightward so as to open or close the conventional gardening fluid connection
device. When the
fitting sleeve is stopped after being rotated, the user knows the conventional
gardening fluid
connection device is located on an opening position or a closing position.
Alternatively, the user
knows the conventional gardening fluid connection device is located on the
opening position or
the closing position after pressing the fitting sleeve. Furthermore, a
conventional gardening
fluid connection device such as disclosed in US Patent No. 7021669 contains an
L-shaped
depression defined in the fitting sleeve so that the stop rib of the fitting
sleeve slides in a
stopping face of the depression when being rotated to the closing position or
the opening
position, hence the conventional gardening fluid connection device is not
positioned.
SUMMARY
[0003] A primary aspect of the present invention is to provide a gardening
fluid
coupling device which is opened or closed easily by way of the stop rib and
each locking
element of the body, each spaced engagement tooth of the fitting sleeve, and
the resilient
element.
[0004] Another aspect of the present invention is to provide a gardening fluid
coupling
device in which each locking element rotates from a first side of each spaced
engagement
tooth toward the second side of each spaced engagement tooth, wherein each
spaced
engagement tooth is pushed by the resilient element to contact with the stop
rib and each
locking element of the body and to rotate toward the second side of each
spaced
1

engagement tooth, and each locking element rotates to the second side of each
spaced
engagement tooth, such that it is easy to distinguish whether the gardening
fluid coupling
device is opened or closed.
[0005] In an aspect, a gardening fluid connection device comprises a body on
which multiple retainers are retained, a resilient element, and a fitting
sleeve which are fitted
on a first end of the body. The fitting sleeve includes multiple spaced
engagement teeth and
the resilient element abuts against the body and the fitting sleeve. Also, the
fitting sleeve
rotates along the body reciprocatingly and pushes the resilient element so as
to open or close
the gardening fluid coupling device, hence the multiple retainers of the body
are removed or
retained when the fitting sleeve presses the resilient element or is pushed by
the resilient
element so that the multiple retainers of the body connect with or remove from
a water spray
gun or a sprinkler. The body includes a stop rib arranged thereon so that the
multiple spaced
engagement teeth of the fitting sleeve are pushed by the resilient element to
abut against the
stop rib of the body. The body also includes at least one locking element
formed inside the
stop rib, wherein each locking element is located on a first side of each
spaced engagement
tooth, and wherein a width of each spaced engagement tooth is equal to a
rotation distance
of the fitting sleeve, such that the fitting sleeve is rotated reciprocatingly
so as to open or
close the gardening fluid coupling device by way of the stop rib and each
locking element of
the body, each spaced engagement tooth of the fitting sleeve, and the
resilient element.
Further, each locking element is stopped when moving to a second side of each
spaced
engagement tooth.
[0006] In another aspect, a gardening fluid connection device comprises a body
on which multiple retainers are retained, a resilient element, and a fitting
sleeve which are
fitted on a first end of the body. The fitting sleeve includes multiple spaced
engagement
teeth and the resilient element abuts against the body and the fitting sleeve.
Also, the fitting
sleeve rotates along the body reciprocatingly and pushes the resilient element
so as to open
or close the gardening fluid coupling device, hence the multiple retainers of
the body are
removed or retained when the fitting sleeve presses the resilient element or
is pushed by the
resilient element so that the multiple retainers of the body connect with or
remove from a
water spray gun or a sprinkler. The body further includes at least one
retaining element, and
the fitting sleeve further includes at least one shoulder respectively located
above and
contacting with the retaining element so as to maintain the fitting sleeve on
a closing

position and not press downward when the fitting sleeve rotates to an opening
position. The
shoulder removes from the retaining element of the body so that the fitting
sleeve presses the
resilient element to release the multiple retainers, and the multiple
retainers connect with or
remove from the water spray gun or the sprinkler.
[0007] In yet another aspect, a gardening fluid connection device comprises a
body on which multiple retainers are retained, a resilient element, and a
fitting sleeve which
are fitted on a first end of the body. The fitting sleeve includes multiple
spaced engagement
teeth and the resilient element abuts against the body and the fitting sleeve.
Also, the fitting
sleeve rotates along the body reciprocatingly and pushes the resilient element
so as to open
or close the gardening fluid coupling device, hence the multiple retainers of
the body are
removed or retained when the fitting sleeve presses the resilient element or
is pushed by the
resilient element so that the multiple retainers of the body connect with or
remove from a
water spray gun or a sprinkler. The body includes a stop rib arranged thereon
so that the
multiple spaced engagement teeth of the fitting sleeve are pushed by the
resilient element to
abut against the stop rib of the body. The body also includes at least one
locking element
formed inside the stop rib, wherein each locking element is located on a first
side of each
spaced engagement tooth, and wherein a width of each spaced engagement tooth
is equal to
a rotation distance of the fitting sleeve, such that the fitting sleeve is
rotated reciprocatingly,
and each locking element rotates from a first side of each spaced engagement
tooth toward
the second side of each spaced engagement tooth. The body further includes at
least one
retaining element, and the fitting sleeve further includes at least one
shoulder respectively
located above and contacting with the one or more than one retaining element
so as to
maintain the fitting sleeve on a closing position and not press downward when
the fitting
sleeve rotates to an opening position. The shoulder removes from the one or
more than one
retaining element of the body so that the fitting sleeve presses the resilient
element to release
the multiple retainers, and the multiple retainers connect with or remove from
the water
spray gun or the sprinkler.

DETAILED DESCRIPTION
[0020] With reference to FIGS. 1 to 3, a gardening fluid connection device
according to a preferred embodiment of the present invention comprises: a body
10 on
which multiple retainers 101 are retained, a screwing sleeve 20 mounted on a
first end of the
body 10 and configured to connect with a water hose, a resilient element 30,
and a fitting
sleeve 40, which are fitted with a second end of the body 10 The resilient
element 30 and the
fitting sleeve 40 abut against each other so that the fitting sleeve 40
rotates along the body
reciprocatingly and pushes the resilient element 30 so as to open or close of
the
gardening fluid coupling device, hence the multiple retainers 101 of the body
10 are
4
CA 2998145 2018-03-15
removed or retained when the fitting sleeve 40 presses the resilient element
30 or is pushed
by the resilient element 30 so that the multiple retainers 101 of the body 10
connect with or
remove from a water supply device, such as a water spray gun or a sprinkler.
The body 10
includes multiple flexible teeth 11 arranged on the first end thereof, a
threaded section 12
formed inside the multiple flexible teeth 11 and configured to screw with the
screwing
sleeve 20, a stop rib 13 arranged on the second end of the body 10, one or
more than one
locking element 14 (i.e., each locking element 14 is a boss) formed inside the
stop rib 13,
multiple limitation elements 15 arranged inside the one or more than one
locking element 14
and away from the stop rib 13, and multiple spaced orifices 16 configured to
accommodate
the multiple retainers 101 respectively and located adjacent to the stop rib
13. In this
embodiment, each of the multiple limitation elements 15 is defined between any
two of the
multiple spaced orifices 16 and is an extending rib.
[0021] Referring further to FIGS. 1 to 3, the body 10 includes one or more
than
one retaining element 17 (which is a protrusion). Each retaining element 17 is
defined
between each limitation element 15 and each spaced orifice 16. The body 10
further includes
a surround seat 18 arranged on a middle section thereof and abutting against
the resilient
element 30. In an embodiment, the resilient element 30 is a spring. The
fitting sleeve 40 (as
shown in FIG. 4) includes a fixing seat 41 formed on a middle section of an
inner wall of the
fitting sleeve 40 and abutting against the resilient element 30. Multiple
guide zones 42 are
defined by elongated ribs and correspond to the multiple spaced orifices 16
respectively,
wherein the multiple guide zones 42 abut against the multiple retainers 101
individually.
Multiple spaced engagement teeth 43 are defined between any two adjacent of
the multiple
guide zones 42 so as to be pushed by the resilient element 30 and contacts
with the stop rib
13 of the body 10. And the one or more than one locking element 14 is located
beside each
of the multiple spaced engagement teeth 43 so that the resilient element 30
pushes the fixing
seat 41 of the fitting sleeve 40 and the surround seat 18 of the body 10.
[0022] The fitting sleeve 40 further includes one or more than one elongated
shoulder 44 respectively corresponding to and located above the one or more
than one
retaining element 17 so that the one or more than one elongated shoulder 44
moves across
the one or more than one retaining element 17 when the fitting sleeve 40 is
rotated. Each
elongated shoulder 44 has a stopping face 45 defined on one side thereon so as
to form a
defining space 46, such that each limitation element 15 is located in the
defining space 46
CA 2998145 2018-03-15
and is limited by each elongated shoulder 44 and the stopping face 45 when the
fitting
sleeve 40 rotates reciprocatingly. A width of each of the multiple spaced
engagement teeth
43 is equal to a rotation distance of the fitting sleeve 40 in an embodiment.
100231 Referring to FIG. 5, when the fitting sleeve 40 is located on a closing
position, each elongated shoulder 44 is located above each retaining element
17 of the body
so that the fitting sleeve 40 does not press each retaining element 17 while
the fitting
sleeve 40 is pushed by the resilient element 30 so that each spaced engagement
tooth 43 is
biased against the stop rib 13 of the body 10, and each locking element 14 is
located on a
first side of each spaced engagement tooth 43 (as illustrated in FIG. 6). In
this arrangement,
each limitation element 15 of the body 10 contacts with the stopping face 45
of the fitting
sleeve 40 and each of the multiple retainers 101 is pushed by each of the
multiple guide
zones 42 so as to connect with a coupling opening of the water supply device.
When the
fitting sleeve 40 is rotated to an opening position (as shown in FIGS. 7 and
8), each
elongated shoulder 44 moves away from each retaining element 17 so that the
fitting sleeve
40 presses the resilient element 30, and each locking element 14 and each
spaced
engagement tooth 43 are pushed by the fitting sleeve 40 to press the resilient
element 30 so
that each spaced engagement tooth 43 removes from the stop rib 13 and moves
along each
locking element 14. When each locking element 14 moves to a second side of
each spaced
engagement tooth 43 (as illustrated in FIG. 9), each spaced engagement tooth
43 is not
forced by each locking element 14 and is pushed by the resilient element 30 so
as to urge the
stop rib 13 and each locking element 14 to rotate toward the second side of
each spaced
engagement tooth 43. Preferably, each limitation element 15 contacts with each
elongated
shoulder 44 so as to maintain the fitting sleeve 40 on the opening position,
and the fitting
sleeve 40 (as shown in FIG. 10) and the resilient element 30 are pressed until
each retainer
101 of the body 10 removes from each guide zone 42, thus removing or fixing
each retainer
101 from or into the coupling opening of the water spray gun or the sprinkle.
Thereby, the
gardening fluid coupling device is opened or closed easily by way of the stop
rib 13 and
each locking element 14 of the body 10, each spaced engagement tooth 43 of the
fitting
sleeve 40, and the resilient element 30.
