WATER NOZZLE WITH TRIGGER LOCK AND FLOW CONTROL
[0001] CROSS-REFERENCE TO RELATED APPLCIATIONS
[0002] This application claims priority to and the benefit of U.S. Provisional Application No. 63 / 587, 482, filed on October 3, 2023, which is hereby incorporated by reference in its entirety.BACKGROUND
[0003] Various water and spray nozzles are known which incorporate means for varying the pattern taken by the water ejected from the nozzle means at the front end of the barrel. Usually, this variation is achieved by adjustment of said nozzle means or valve means associated therewith at the front end of the barrel.
[0004] These nozzles have activation triggers to turn on and off the water as well as trigger locks to make the nozzles easier to use. What is needed is an improved nozzle with increased flow, improved flow control, and an improved locking mechanism for the nozzle.SUMMARY
[0005] In one aspect, a water nozzle having a trigger lock and a flow control is provided. The water nozzle may also include a body defining a fluid inlet and a spray outlet on opposing ends of the body, a fluid channel extending between the fluid inlet and the spray outlet internal to the body, and a trigger attachable to the body and configured to control a flow of fluid through the fluid channel. In some aspects, the opening is configured to be connected to a water source, such as a garden hose. The trigger lock may be rotatable from a first unlocked position to a second locked position, where when the trigger lock is in the second locked position the trigger is locked in a depressed position, and the flow control may be co-axial with the trigger lock and rotatable between a first position and a second position to adjust the flow of fluid through the fluid channel. The water nozzle may also include a valve positioned in the fluid channel, where the valve is movable between a closed position and an open position to control the flow of fluid out of the spray outlet. The trigger may be operably connected to the valve, such that depression of the trigger is effective to move the valve between the closed position and the open position, and release of the trigger is effective to move the valve from the open position to the closed position.
[0006] In some aspects, the flow control includes a flow control valve for adjusting the flow of fluid through the fluid channel. In some aspects, the flow control valve is a ball valve. In some aspects, the flow control also includes an outer operable member having a flow control knob integrally attached thereto. Forward movement of the flow control knob may be effective to rotate the flow control between the first position and the second position. Backward movement of the flow control knob may be effective to rotate the flow control between the second position and the first position. In the first position, flow of fluid through the fluid channel may be unrestricted, and in the second position, flow of fluid through the fluid channel may be fully restricted. In some aspects, the flow control know is configured for freedom of motion between the first position and the second position to control the flow of fluid through the fluid channel.
[0007] In some aspects, the trigger lock comprises an outer operable member having a locking knob integrally attached thereto. Forward movement of the locking knob may be effective to lock the trigger in the depressed position. Backward movement of the locking knob may be effective to release the trigger from the depressed position. In some aspects, the trigger lock also includes an elastic member configured to bias the trigger in the depressed position when locked, and where release of the elastic member is effective to release the trigger from the depressed position. In some aspects, the trigger lock also includes at least one locking protrusion configured to contact a reciprocal protrusion extending from an internal surface of the trigger when the trigger lock is in the locked position, such that the mechanical engagement between the at least one locking protrusion and the reciprocal protrusion is effective to bias the trigger in the locked position.
[0008] In another aspect, a water nozzle is provided, the water nozzle having a body defining a fluid inlet and a spray outlet on opposing ends of the body, a fluid channel extending between the fluid inlet and the spray outlet internal to the body, a trigger attachable to the body and configured to control a flow of fluid through the fluid channel, a valve positioned in the fluid channel, wherein the valve is movable between a closed position and an open position to control the flow of fluid out of the spray outlet, and a flow control system comprising a flow control valve for adjusting the flow of fluid in the fluid channel, and a flow control switch rotatable between a first position and a second position to adjust the flow control valve. The trigger may be operably connected to the valve, such that depression of the trigger is effective to move the valve between the closed position and the open position, and release of the trigger is effective to move the valve from the open position to the closed position.
[0009] In some aspects, the flow control valve is a ball valve. In some aspects, the flow control switch comprises an outer operable member having a flow control knob integrally attached thereto, wherein movement of the flow control switch is effectuated via the flow control knob. Forward movement of the flow control knob may be effective to rotate the flow control between the first position and the second position. Backward movement of the flow control knob is effective to rotate the flow control between the second position and the first position. In some aspects, flow of fluid through the fluid channel is unrestricted when the flow switch is in the first position, and flow of fluid through the fluid channel is fully restricted when the flow switch is in the second position. In some aspects, the flow control knob is configured for freedom of motion between the first position and the second position to control the flow of fluid through the fluid channel.
[0010] In a further aspect, a water nozzle is provided, the water nozzle having a body defining a fluid inlet and a spray outlet on opposing ends of the body, a fluid channel extending between the fluid inlet and the spray outlet internal to the body, a trigger attachable to the body and configured to control a flow of fluid through the channel, a trigger lock system comprising a trigger lock rotatable about the trigger for locking the trigger in a depressed position. The trigger lock may have an outer operable member rotatable between a first unlocked position and a second locked position for locking the trigger in the depressed position. In some aspects, the trigger lock also includes an elastic member configured to bias the trigger in the depressed position when locked, and where release of the elastic member is effective to release the trigger from the depressed position. In some aspects, the trigger lock also includes at least one locking protrusion configured to contact a reciprocal member of the trigger when the trigger lock is in the locked position, such that the mechanical engagement between the at least one locking protrusion and the reciprocal member is effective to bias the trigger in the locked position.

[0035] The disclosure will be described in more fully hereinafter with reference to the accompanying drawings, in which example embodiments are shown. This disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.
[0036] A water nozzle for a garden hose and, more specifically, a water nozzle having a combined trigger lock and flow control system is provided. FIGS. 1A-1C depict a water nozzle having a combined trigger lock and flow control system attached thereto. In embodiments, the water nozzle 100 has a body portion 102 and a head portion 104. The body portion 102 may include a handle 106 and a trigger 108 defining a trigger gap 110 therebetween. In use, the trigger 108 may be depressed, moving the trigger 108 in a direction towards the handle 106. In depressing the trigger 108, the trigger gap 110 between the trigger 108 and the handle 106 may be closed. Depressing the trigger 108 may also permit fluid (e.g., water) flow through the nozzle 100. For example, the nozzle 100 may be attached to an external water source (e.g., a hose, such as a garden hose) via the inlet opening 112 positioned on a distal end 107 of the handle 106. When the trigger 108 is depressed, water may be permitted to flow from the water source (not shown) into the opening 112, through the nozzle 100, and be expelled through a spray outlet 114 defined within a distal end 105 of the head portion 104 of the nozzle. In some embodiments, the trigger 108 is rotatable about a trigger axis 116, which enables movement of the trigger 108 towards and away from the handle 106 to control fluid flow through the nozzle 100.
[0037] As shown in FIGS. 1A-1C, the water nozzle 100 may also include a combined trigger lock and flow control system 120 positioned on the body portion 102 of the nozzle 100 adjacent to a proximal end 109 of the trigger 108. In embodiments, the system 120 includes a trigger lock 130 and a flow control 140. The trigger lock 130 and the flow control 140 may be disposed concentrically on both sides of the body portion 102 of the nozzle 100, as shown in FIG. 1C. For example, the trigger lock 130 may be positioned concentrically around the flow control 140, or vice versa. Placement of the trigger lock and flow control system 120 may enable ambidextrous use. The trigger lock 130 and the flow control 140 may also be arranged so that neither component interferes with the other, as shown in greater detail in FIG. 2. For example, the flow control 140 may be disposed adjacent to the trigger lock 130 such that the flow control 140 can move (e.g., rotate) in a plane that is parallel to a plane in which the trigger lock 130 rotates.
[0038] The position of the combined trigger lock and flow control system 120 may enable users to conveniently engage the trigger 108 to produce flow through the nozzle 100, lock the trigger 108 to sustain the fluid flow, and further control flow of fluid suing the flow control 140, all with one hand. That is, while holding the nozzle 100, a user may depress the trigger 108 while also controlling the trigger lock 130 and / or flow control 140 with their thumb. The position of the combined trigger lock and flow control system is not only ergonomic, but the dual-side placement of the trigger lock 130 and flow control 140 components also permits users to operate the nozzle 100 in either hand.
[0039] Referring now to FIGS. 2-3, the combined trigger lock and flow control system 120 is shown in greater detail. In embodiments, the trigger lock 130, also shown in greater detail in FIG. 4, includes external mounting portions 132 positioned on each side of the body portion 102 of the nozzle. Each mounting portion 132 may have a locking knob 134 integrally formed thereon. The locking knobs 134 may extend outward from the nozzle 100, so that a user may use said locking knobs 134 to control rotation of the trigger lock 130 with respect to the nozzle 100. The trigger lock 130 may also include a bridging member 136 connecting the external locking members 132. When assembled, the bridging member 136 may be covered by the upper portion 118 of the trigger 108, such that the bridging member 136 is not externally visible or accessible.
[0040] In some embodiments, the trigger lock 130 also includes at least one locking protrusion 137. In a preferred embodiment, the trigger lock 130 includes two locking protrusions. The locking protrusions 137 may be positioned on the bridging member 136 of the trigger lock 130, and may be configured to engage with reciprocal protrusions 119 (as shown in FIG. 6) extending from the upper portion 118 of the trigger 108.
[0041] In some embodiments, the trigger lock 130 also includes a resilient member 138. The resilient member 138 may be effective to bias the trigger 108 in the locked (depressed) position. The resilient member 138 may also facilitate quick release of the trigger 108 from the locked position, as described in greater detail with respect to FIGS. 5A-5B. In some embodiments, as shown in FIG. 3, the resilient member 138 has a U-shape and is configured to pass through the nozzle 100 between the body 104 and the trigger 108. However, it would be understood that any suitable resilient member effective to bias the trigger 108 in the locked position may be used.
[0042] Referring now to FIGS. 5A-5B, the trigger lock 130 is shown in the unlocked position 200 (FIG. 5A) and the locked position 202 (FIG. 5B) . In the unlocked position 200, the trigger 108 may project outward from the handle 106, defining the trigger gap 110 therebetween. Water flow through the nozzle may not be permitted. When the trigger 108 is fully depressed, as shown in FIG. 5B, the trigger lock 130 may be moved to the locked position 202. For example, when the trigger 108 is fully depressed, the upper portion 118 of the trigger 108 extends away from the body 102 of the nozzle 100, thereby permitting the locking knob 134 to be rotated forward from the unlocked position 200 to the locked position 202.
[0043] In the locked position 200, as shown in greater detail in FIG. 6, the locking protrusions 137 of the trigger lock 130 may be rotated forward, via user engagement with the locking knob 134, so that the locking protrusions 137 are engaged with the reciprocal protrusions 119 extending from within the upper portion 118 of the trigger 108. The frictional engagement between the locking protrusions 137 and the reciprocal protrusions 119 is effective to maintain the locked position 202 of the trigger lock 130. Maintaining the trigger 108 in this depressed (i.e., locked) position advantageously permits water flow through the nozzle 100 at a maximum flow rate without requiring the user to apply sustained pressure to the trigger 108.
[0044] To release the locking protrusions and revert back to the unlocked position, or to reduce water flow, the user may manually move the knob back to rotate the lock and disengage the protrusions. Alternatively, the user may depress the trigger further to engage the resilient member and activate the spring loaded release. Release of tension in the resilient member will automatically rotate the lock back to the unlocked position.
[0045] For example, the resilient member 138 may spring load the trigger lock 130 when the trigger 108 is in the locked position. To release the trigger 108, a user may further depress the trigger 108 to release the tension stored in the resilient member 138 and unlock the trigger 108. Unlocking of the trigger 108 will rotate the trigger lock 130 back to its resting, unlocked position. In other embodiments, the trigger 108 may be manually unlocked by further depressing the trigger 108 to disengage the locking protrusions 137 from the reciprocal protrusions 119 of the trigger 108, and manually rotating, via the locking knob 134, the trigger lock 130 to the unlocked position.
[0046] Referring back to FIG. 3, passage 122 may be defined within the body 102 of the nozzle 100, adjacent to the handle 106 and the upper portion 118 of the trigger 108, for containing at least a portion of the flow control 140. Any external components of the flow control 140 may be arranged concentrically within the external mounting members 132 of the trigger lock 130.
[0047] In embodiments, the flow control 140, as shown in greater detail in FIG. 7, includes external members 142 positioned on either side of the body 102 of the nozzle 100. Preferably, the external members 142 are sized and arranged to be positioned within the external mounting members 132 of the trigger lock 130. Each external member 142 may also have a flow control knob 144 integrally attached thereto. The flow control knob 144 may be configured to be contacted by a user to control the flow of water through the nozzle 100 while water is already flowing therethrough (i.e., when the trigger 108 is depressed to permit flow) .
[0048] In embodiments, the flow control 140 also includes a flow control valve 146 attachable to the external members 142. The valve 146 may be rotatably disposed within the channel 122 of the body portion 102, such that the valve 146 is in fluid communication with the fluid flow path 150 (described further with reference to FIG. 10) . In a preferred embodiment, the flow control valve 146 is barrel-shaped to fit within the channel and operates similar to a ball valve. However, any other suitable valve may be used. In some embodiments, the flow control 140 also includes a mounting conduit 148 on one or both sides of the flow control 140. The mounting conduit 148 may be positioned between the valve 146 and the external member (s) 142 to facilitate the connection therebetween. In other embodiments (not shown) , the flow control 140 only includes the external members 142, the flow control knobs 144, and the valve 146.
[0049] Rotation of the external member (s) 142, via the flow control knob (s) 144, may be effective to rotate the valve 146 within the channel 122 to more precisely control water flowthrough the nozzle 100 while in use. For example, as shown in FIGS. 8A-8B, the flow control 140 may be rotatable between a first position 300 (FIG. 6A) and a second position 302 (FIG. 6B) . The first position 300, as shown in FIG. 6A, may be an “open” position, such that flow through the nozzle 100 is unrestricted by the valve 146 such that water may freely flow through a valve opening 147 defined therein. The unrestricted state, where the flow control 140 is in the first position 300, is also shown in greater detail in FIG. 9. The second position 302, as shown in FIG. 6B, may be a “closed” position, such that flow through the nozzle 100 is fully restricted by the valve 146. The first position 300 and the second position 302 may be separated by about 90°.
[0050] In some embodiments, the flow control 140 is freely movable between the first position 300 and the second position 302 to control fluid flow to any varying degree corresponding to the extent to which the flow control knob 144 has been rotated. Starting from the first position 300 where flow through the valve 146 is unrestricted, the flow control knob 144 may be rotated forward by a user to gradually restrict flow through the valve 146 until the flow control 140 is in the second position 302, where flow through the valve 146 is fully restricted. For example, rotation of the flow control knob 144 forward by 45° may result in a 50%reduction in flow through the valve 146. To increase flow through the valve 146, the flow control knob 144 may be rotated backward in a direction towards the first position 300.
[0051] Referring now to FIG. 10, a cross-sectional view of the water nozzle 100 is shown. In embodiments, the water nozzle 100 includes a fluid flow path 150 extending between the inlet opening 112 and the spray outlet 114. This fluid flow path 150 may include three portions: an inlet portion 152, a body portion 154, and an outlet portion 156. In use, water may enter the nozzle 100 through the inlet 112, and pass through the inlet portion 152 of the flow path 150. The valve 146 of the flow control 140 may be positioned between the inlet portion 152 and the chamber portion 154 of the flow path 150 to control the extent to which water may be permitted to pass from the inlet portion 152 to the chamber portion 154.
[0052] In embodiments, the flow path 150 also includes an outlet passage 158 positioned between the chamber portion 154 and the outlet portion 156 of the flow path 150. Expulsion of water through spray outlet 114 may be dependent upon the flow of water through the outlet passage 158 from the chamber portion 154 of the flow path.
[0053] For example, the nozzle 100 may also include a plunger valve 160 having a trigger end 162 and a plunger end 164. The trigger end 162 may be operably connected to the upper portion 118 of the trigger 108, and the plunger end 164 may be configured to seal the outlet passage 158 when the nozzle 100 is not in use. When flow through the nozzle 100 is desired, a user may depress the trigger 108, which draws the plunger end 164 of the plunger valve 160 away from the outlet passage 158, via the connection between the trigger end 162 of the valve 160 and the upper portion 118 of the trigger. Removal of the plunger end 164 of the valve 160 from the outlet passage 158 permits water to pass through the outlet passage 158 from the chamber portion 154 of the flow path 154 and into the outlet portion 156, to be expelled through the spray outlet 114.
[0054] A user may therefore roughly control water flow through the nozzle 100 by the extent to which the trigger 108 is depressed. That is, it would be understood that the extent to which the trigger 108 is depressed corresponds directly with the distance that the plunger end 164 of the valve 160 is pulled away from the outlet opening 158. When the distance between the plunger end 164 and the outlet opening 158 is small, a limited amount of water may be permitted to pass through the opening 158. In contrast, when the distance between the plunger end 164 and the outlet opening 158 is large, e.g., when the trigger 108 is fully depressed, a maximum amount of water may be permitted to pass through the opening 158. The user may also more precisely control flow through the nozzle 100 via the flow control 140, as previously described.
[0055] In some embodiments, as shown in FIG. 11, a water nozzle 400 may have only a flow control 440. The flow control 440 may be the same as flow control 140, as described with respect to FIGS. 1-10. For example, the water nozzle 400 may have a body portion 402, a head portion 104, and a handle 106 with a trigger 108 pivotably attached thereto. A trigger gap 410 may be defined between the handle 406 and the trigger 408, such that when the trigger 408 is depressed, the trigger gap 410 may be closed. The nozzle 400 may also include an inlet opening 412 positioned on the distal end 407 of the handle 406, and a spray outlet 414 positioned on the distal end 405 of the head portion 404 of the nozzle 400. In embodiments, the flow control 440 is positioned adjacent to an upper portion 418 of the trigger 408. As shown in FIG. 11, the flow control 440 may include one or more external member 442 each integrally attached to a flow control knob 444. The flow control 440, like flow control 140, may be described in additional detail with reference to FIGS. 1-10.
[0056] In embodiments, a water nozzle may have only a trigger lock. In some embodiments, the water nozzle 500, as shown in FIG. 12, may have a trigger lock 530 that is the same as trigger lock 130, as described with respect to FIGS. 1-10. For example, the nozzle 500 may have a body portion 502, a head portion 504, and a handle 106 with a trigger 108 pivotably attached thereto. A trigger gap 510 may be defined between the handle 506 and the trigger 508, such that when the trigger 508 is depressed, the trigger gap 510 may be closed. The nozzle 500 may also include an inlet opening 512 positioned on the distal end 507 of the handle 506, and a spray outlet 514 positioned on the distal end 505 of the head portion 504 of the nozzle 500. In embodiments, the trigger lock 530 is positioned adjacent to an upper portion 518 of the trigger 508. As shown in FIG. 12, the trigger lock 530 may include one or more external mounting members 532, each having a locking knob 534 integrally attached thereto. The trigger lock 530, like trigger lock 130, may be described in additional detail with reference to FIGS. 1-10.
[0057] In other embodiments, as shown in FIGS. 13A-14B, the water nozzle 600 may have a trigger lock 620 configured for pivotal rotation about an axis. For example, referring to FIGS. 13A-13B in greater detail, the water nozzle 600 has a body portion 602, a head portion 604, and a handle 606 with a trigger 608 pivotably attached thereto via a trigger pivot 616. A trigger gap 610 may be defined between the handle 606 and the trigger 608. When the trigger 608 is depressed, the trigger gap 610 may be closed.
[0058] In embodiments, the nozzle 600 includes an inlet opening 612 positioned on the distal end 607 of the handle 606, and a spray outlet 614 positioned on the distal end 605 of the head portion 604 of the nozzle 600. When the trigger 608 is depressed, water may therefore flow from a water source (e.g., a garden hose) into the inlet opening 612, through the nozzle 100, and out through the spray outlet 614.
[0059] In embodiments, a trigger lock 620 is attached to an upper portion 618 of the trigger 108, as shown in greater detail in FIG. 13B. The trigger lock 620 may include an outer locking surface 622 configured to pivot about a locking pivot 624 between an unlocked position and a locked position, as described in greater detail with respect to FIGS. 14A-14D. The trigger lock 620 may also include a spring 626 configured to bias the trigger lock 620 in the locked position.
[0060] Referring now to FIGS. 14A-14D, the trigger lock 620 may be pivotable between an unlocked position 700 (FIGS. 14A-14B) and a locked position 702 (FIGS. 14C-14D) . In the unlocked position 700, the trigger 608 may extend outward from the handle 608. A locking protrusion 628 and a locking gap 630, as shown in FIG. 14B, may not be in contact with any portion of the nozzle 100 when the trigger lock 620 is in the locked position 700.
[0061] When the trigger 608 is fully depressed, as shown in FIGS. 14C-14D, the trigger lock 620 may be pivoted into the locked position 702. In the locked position 702, the locking protrusion 628 may be secured within a reciprocal slot 632 within the upper portion 618 of the trigger 608. The locking gap 630 may also be in contact with a reciprocal protrusion 634 extending from the body 102 of the nozzle 100 to further secure the trigger lock 620 in the locked position 702 so that the trigger 608 remains depressed.
[0062] In some embodiments, the trigger lock 620 may be manually release from the locked position 702 by pivoting the locking surface 622 backward (i.e., in the direction away from the body 602 and head 604 of the nozzle 600) to release the locking protrusion 628 from the reciprocal slot 632. The outward pivoting of the locking surface 622 may also release frictional attachment between the locking gap 630 and the reciprocal protrusion 634. The trigger 608 may then be released and the trigger lock 620 reverted to the unlocked position 700. In other embodiments, the spring 626 may enable a quick release of the trigger lock 620. For example, the trigger 608 may be further depressed to engage the spring 626, where release of the tension stored in the spring 626 may be effective to disengage the trigger lock 620 and revert the trigger 608 to an extended, released position where the trigger lock 620 is in the unlocked state 700.
