Definitions

  • Example embodiments generally relate to watering equipment and, more particularly, relate to a water applicator that employs an operable member that can easily be transitioned between locked and unlocked states.
  • Watering equipment includes such devices as hoses, hose reels, spray guns, spray nozzles, spray lances, water taps (or spigots) and the like. These devices are often used to apply water from the water tap to a garden, plant or other target using the hose along with some form of water application device (e.g., an applicator such as a spray gun, spray nozzle or spray lance).
  • an applicator such as a spray gun, spray nozzle or spray lance
  • gardeners often perceive the need to have different tools for different specific situations. Thus, gardeners desire applicators with different characteristics.
  • Some example embodiments may therefore provide a water application device design that provides an improved locking assembly.
  • some embodiments may provide a locking member in an ergonomically advantageous location that may enable the user (i.e., the gardener) to operate the operable member and also lock the operable member in a desired position with one hand.
  • Some embodiments may also or alternatively enable the arrest function (i.e., locking and unlocking) of the operable member to be easily engaged and disengaged by simple compression of the operable member.
  • the ergonomics and function of water application devices can therefore be improved and the operator experience may be more enjoyable.
  • a water application device according to the invention is defined in the appended claims.
  • example embodiments described herein provide an improved design for a water application device.
  • example embodiments may enable an operator or user to lock a flow control assembly in the on state, often with the same hand that supports the device.
  • the flow control assembly may be controlled using a locking member that is placed at a convenient and ergonomically advantageous location on the trigger (or operable member) of the device.
  • the locking member may be activated and deactivated by movement in the horizontal direction, which is quite convenient and natural using the index finger of the hand holding the device.
  • the locking member may be provided to interact with a locking head via a unique structure that alternately allows the trigger to be switched between locked and unlocked states with each compression when the locking member is in the locked position.
  • FIG. 1 illustrates a block diagram of a modular water application device 10 in accordance with an example embodiment.
  • the modular water application device 10 includes a main body 20, an operable member 30 and an applicator head 40.
  • the main body 20 is graspable along a portion thereof by an operator.
  • the graspable portion defines a handle portion 22 of the main body 20, and the handle portion 22 may be provided between an outlet portion 24 and an inlet potion 26.
  • the main body 20 houses a flow control assembly 50 configured to enable the device 10 to execute a control function relative to flow of water through the device 10 (e.g., from the inlet portion 26 to the outlet portion 24).
  • the flow control assembly 50 may include an on/off control assembly 52 and a volume control assembly 54.
  • the operable member 30 is attached to the main body 20 to interface with the flow control assembly 50 to alternately start and stop flow through the device 10 based on a position of the operable member 30.
  • the operable member 30 may act as an operator to open or close (partially or fully) a valve or other flow control device in the flow control assembly 50.
  • the operable member 30 may interface with the on/off control assembly 52 of the flow control assembly 50.
  • the flow control assembly 50 may further enable a volume control function to be performed so that the flow can not only be turned on and off, but also modulated to at least some degree based on operator control.
  • the volume control assembly 54 may be an example of a structure to perform such a function. However, the volume control assembly 54 may be omitted in some examples.
  • the applicator head 40 may be attachable to an outlet portion 24 of the main body 20 to apply water passing through the applicator head 40 based on an application characteristic of the applicator head 40.
  • the applicator head 40 may be a selected one of a number of different applicator heads and each of the different applicator heads may have a different structure and/or configuration to support different flow application needs or desires.
  • example embodiments may provide an improved ergonomic design that enables the operator to control the application of water via operation of the operable member 30 and also lock the operable member 30 in an on position with the same hand (i.e., so that two-handed volume control can be avoided).
  • a locking assembly 70 may be provided, and the locking assembly 70 may selectively interact between the operable member 30 and the main body 20 to lock or unlock the operable member 30 in position relative to the main body 20.
  • the locking assembly 70 may provide this service via the inclusion of a locking member on the operable member 30 itself, with the locking member being oriented so that it moves in a direction perpendicular to the direction of extension of the locking member and is provided at a portion of the locking member at which the index finger is normally located.
  • the index finger may easily push the locking member in a desired position without sacrificing the grip on the device.
  • the locking assembly 70 itself is provided to lock and unlock with each subsequent compression of the operable member.
  • the operable member 30 is pivotally attached to the main body 20 to interface with the flow control assembly 50 to alternately provide flow when pivoted to a compressed position and stop flow when pivoted to an extended position.
  • the operable member 30 is provided to have a length extending substantially parallel to a longitudinal centerline of the handle portion 22.
  • the operable member 30 interfaces with a locking member of the locking assembly 70, such that the locking member is disposed at a surface of the operable member 30 that faces away from the main body 20.
  • the locking member may be configured to enable the operator to lock the operable member in a flow provision state (i.e., an "on" state) based on positioning the locking member in a locked state.
  • the locking member is configured to move between the locked state and an unlocked state via movement along the first surface in a direction substantially perpendicular to the longitudinal centerline of the handle portion (and the direction of extension of the operable member or longitudinal centerline of the operable member).
  • FIG. 2 illustrates an exploded view of a device 100 that forms one example of the device 10 shown in FIG. 1 .
  • the device 100 includes a main body 110 that is provided as an example of the main body 20 of FIG. 1 .
  • the main body 110 has an outlet portion 112 and inlet portion 114 that serve as examples of the outlet portion 24 and the inlet potion 26, respectively, of FIG. 1 .
  • the inlet portion 114 may have a threaded engagement to a quick coupling adaptor 116 that may couple to a hose connector.
  • the outlet portion 112 may be configured to mate with a selected on of a plurality of different applicators.
  • Applicator 120 is a specific example of the applicator 40 of FIG. 1 and of one of the different applicators that may mate with the outlet portion 112.
  • the main body 110 may be molded plastic, composite material, metal, or any other suitable material that has sufficient rigidity and can be formed to house chambers, components and/or devices to define a flow channel for water flow from inlet portion 114 to the outlet portion 112.
  • the flow channel may extend along an axis 118 of a handle portion 119 of the main body 110.
  • the outlet portion 112 may be formed along an outlet portion axis 113 that forms an angle relative to the axis 118 in some embodiments.
  • different main body structures may be selected to define corresponding different angles between the axes 118 and 113.
  • An attachment portion 132 may be provided at a rear part of the handle portion 119 to receive a cover assembly 150.
  • a volume control lever 162 may be provided at a receiver 160 of the cover assembly 150.
  • the cover assembly 150 may be provided without the receiver 160 and therefore also without the volume control lever 162 (or any volume control assembly 54).
  • trigger 140 may be provided as an example of the operable member 30 of FIG. 1 .
  • the trigger 140 may be pivotally mounted to the main body 110 between the inlet portion 114 and the intersection between the axes 118 and 113.
  • the pivot point of the trigger 140 is at an end of the trigger 140 corresponding or proximate to the inlet portion 114. It should be appreciated, however, that the pivot point could alternatively be placed at the other end of the trigger (i.e., such that the pivot point is located proximate to the intersection of the axis 118 and 113.
  • the end of the trigger 140 opposite the pivot point may alternatively be compressed toward the main body 110 and extended away from the main body 110 to adjust the on/off control assembly 52 to turn the device 100 on and off, respectively.
  • the trigger 140 includes a locking member 144 that may be configured to mate with a locking head 146 disposed on the main body 110.
  • the locking member 144 and locking head 146 may be examples of components that could make up the locking assembly 70 of FIG. 1 .
  • the locking member 144 could alternatively be provided on the main body 110 and the locking head 146 could be provided on the trigger 140.
  • FIG. 3 illustrates a cross section view of the device 100 of FIG. 2 .
  • a button or other operator of the on/off control assembly 52 may be actuated to provide flow through the device 100.
  • the on/off control assembly 52 may stop flow through the device 100.
  • the locking member 144 and locking head 146 may engage and disengage each other while the locking member 144 is provided in a locked state (or locking position). Meanwhile, when the locking member 144 is in an unlocked state (or unlock position), the locking member 144 and the locking head 146 may not engage each other regardless of the compression of the trigger 140.
  • the trigger 140 When the trigger 140 is compressed from the extended state while the locking member 144 is in the locked state, the trigger 140 may be held proximate to the main body 110 and the on/off control assembly 52 may continuously pass water through the device 100 at a volume determined by the volume control assembly 54.
  • the locking member 144 may be released from the locking head 146 so that the flow control is turned off and flow through the device 100 is stopped.
  • FIG. 4 illustrates a front view of the device 100 of FIGS. 2 and 3 in accordance with an example embodiment.
  • the longitudinal axis 118 (or centerline) of the handle portion is aligned with the direction of extension (and longitudinal axis) of the trigger 140.
  • the locking member 144 is provided to move substantially perpendicular to the longitudinal axis 118 as shown by the arrow 220. Movement of the locking member 144 to one side may place the locking member 144 in an unlock state or position, and movement of the locking member 144 to the other side may place the locking member 144 in a locked state or position.
  • the position of the locking member 144 may impact the interaction between the locking member 144 and the locking head 146 when the trigger 140 is compressed (i.e., into the page in reference to FIG. 4 ).
  • the locked state and unlocked state could be provided on either side in alternative embodiments.
  • the index finger when the operator grasps the device 100, the index finger would tend normally to sit at the top portion of the trigger 140.
  • the location of the locking member 144 may be strategically positioned so that the locking member 144 is in registration with the location upon which the index finger would normally fall when the device 100 is grasped in a comfortable and ergonomically advantageous grip.
  • the operator when the operator determines to change the state of the locking member 144, the operator need only move the index finger from left to right (or vice versa) to apply a force to move the locking member 144 horizontally (i.e., in the direction of arrow 220) to change the state of the locking member 144.
  • the operator's grip is therefore easily maintained throughout the process.
  • the front portion of the trigger 140 may define a first surface 230 (which may be flat or curved).
  • the first surface 230 may face away from the main body 110 and may extend along the longitudinal length of the trigger 140 from an area proximate to the pivot point (e.g., at the bottom of the trigger 140) to a protrusion 235 disposed at a distal end of the trigger 140 relative to the pivot point.
  • the protrusion 235 may serve as a guide to fit the index finger of the operator over the locking member 144 naturally when the operator takes a comfortable grip of the device 100.
  • the locking member 144 may be provided into a receiving slot 240 formed in the first surface 230.
  • the receiving slot 240 (or at least a portion thereof) may pass entirely through the trigger 140 to enable the locking member 144 to be reachable by the operator at the first surface 230, but also engage with the locking head 146.
  • the locking member 144 may define a second surface 244 that may define the visible and accessible portion of the locking member 144.
  • the second surface 244 may have embossing, texture grooves, protrusions, and/or other features thereon to make the second surface 244 distinct from the first surface 230.
  • the second surface 244 may otherwise extend substantially parallel to the first surface 230.
  • the second surface 244 may also be curved or flat to match or at least be somewhat similar to the contours of the first surface 230.
  • the second surface 244 may form the surface that the index finger of the operator actually contacts.
  • FIG. 5 illustrates a closer exploded view of the locking member 144 and the locking head 146 in accordance with an example embodiment.
  • a side of the locking member 144 that is opposite the second surface 244 may include an engagement portion 300 that may be configured to engage the locking head 146.
  • the engagement portion 300 may include a pincer assembly formed from a first member 310 and a second member 312.
  • the first and second members 310 and 312 may extend inwardly toward the main body 110 and toward the locking head 146.
  • the locking head 146 may be rigidly mounted to the main body 110 or internal components of the device 100, such as components forming the flow channel through the device 100.
  • the first and second members 310 and 312 may have a substantially L shape (or J shape) with the short leg of the L (or J) shape forming the distal ends of the first and second members 310 and 312.
  • the short legs of the L (or J) shape may be oriented toward each other to form the pincer assembly.
  • the short legs may form protrusions extending toward each other to define a locking gap 314 bounded by the first and second members 310 and 312, the protrusions (that form the distal ends of the first and second members 310 and 312, and a portion of the locking member 144 that is contacted by the operator to move the locking member 144 between the locked position and the unlocked position.
  • the first and second members 310 and 312 may extend from opposite sides of the back face of the locking member 144 (i.e., a surface opposite the second surface 244) with the first member 310 extending from the top and the second member 312 extending from the bottom of the locking member 144.
  • the first and second members 310 and 312 may extend from positions that are aligned with each other in a line substantially parallel with the longitudinal centerline of the handle portion 119 and axis 118.
  • the locking member 144 may also include guide bars 320 that may enable the locking member 144 to snap fit into the receiving slot 240.
  • the guide bars 320 may also allow the locking member 144 to slide horizontally between the locked and unlocked positions.
  • the receiving slot 240 and/or the locking member 144 may have features (e.g., matching protrusions and grooves) to define distinct locked and unlocked positions when such features align. The features may also or alternatively create sufficient friction to keep the locking member 144 in a given position until the operator uses a finger to put sufficient force to overcome the friction and move the locking member 144 to a different position.
  • the engagement portion 300 When the locking member 144 is provided in the unlocked position (or state), the engagement portion 300 may be misaligned horizontally relative to the locking head 146 and may not contact the locking head 146. Instead, the engagement portion 300 may move alongside the locking head 146 without contacting the locking head 146. In this regard, for example, when the locking member 144 is slid in the direction of arrow 330 and the trigger 140 is compressed, the first and second members 310 and 312 may move alongside the locking head 146 but miss contact with the locking head 146 being spaced apart therefrom in the same direction shown by arrow 330.
  • the engagement portion 300 may be aligned horizontally relative to the locking head 146 so that each compression of the trigger 140 causes the locking member 144 to move with at least some contact between the engagement portion 300 and the locking head 146.
  • the first and second members 310 and 312 may engage an engagement surface 340 of the locking head 146 such that the first member 310 slides over a top surface of the engagement surface 340 and the second member 312 slides over a bottom surface of the engagement surface 340 to lock the engagement portion 300 to the locking head 146 (as described in greater detail below).
  • the trigger 140 will still be held proximate to the main body 110 and flow will be maintained while the trigger 140 is locked in the compressed state. However, if the trigger 140 is compressed again, the engagement portion 300 will be forced out of engagement with the locking head 146 and the trigger 140 will be unlocked and allowed to move to the extended state.
  • FIGS. 6 and 7 show an isolated view of the locking member 144 just prior to a trigger 140 compression while the locking member 144 is in the locked state (or position) from different perspectives.
  • FIG. 6 shows a view from above the locking member 144 and locking head 146
  • FIG. 7 shows a view from the side of the locking member 144 and locking head 146.
  • Distal ends of the first and second members 310 and 312 split to engage opposite sides of the engagement surface 340 and also get deflected in the direction of arrow 344 slightly as they advance along the side of ramp member 345.
  • the ramp member 345 may have a width in the direction of axis 118 that is similar to the combined width of the first and second members 310 and 312 in the same direction.
  • the engagement surface may have a smaller width, but a width that increases long the direction shown by arrow 342.
  • the distal ends of the first and second members 310 and 312 may move in the direction of arrow 354 (straightening out after the slight deformation caused by the interaction with the ramp member 345) to move to the rest surface 360 where the distal ends of the first and second members 310 and 312 are held to keep the trigger 140 at the locked position.
  • the ramp member 345 may be held within the locking gap 314.
  • the rest surface 360 may have a width in the direction of axis 118 (which extends substantially into and out of the page of FIG. 6 ) that is less than the width of the platform 350.
  • the width of the platform 350 may also be less than the width of the ramp member and the widest point of the engagement surface 340. Due to the fact that the platform 350 is wider than the rest surface 360, an ejection ramp 362 may be formed at the intersection of the platform 350 and the rest surface 360. In the locked position, the catch member 352, the ramp member 345 and the ejection ramp 362 may work together hold the distal ends of the first and second members 310 and 312 stationary at the rest surface 360 and locked in place relative to the main body 110 (or other anchoring structure for the locking head 146).
  • the distal ends of the first and second members 310 and 312 may sit on rest surface 360 and be prevented from moving in the direction of arrow 364. This maintains the trigger 140 locked proximate to the main body 110 so that the flow control assembly 50 continues to supply flow through the device 100.
  • the distal ends of the first and second members 310 and 312 may again be urged in the direction of arrow 342. Responsive to this urging, the distal ends of the first and second members 310 and 312 may ride along the ejection ramp 362 to be deflected in the direction of arrow 354 until the distal ends of the first and second members 310 and 312 exit the ejection ramp 362 and compress toward each other to sit alongside ramp member base 365.
  • first and second members 310 and 312 may then be allowed to ride along the ramp member base 365 and the side of the ramp member 345 that is farthest along in the direction of arrow 354 to return to the state shown in FIG. 6 as the trigger 140 goes to the extended position when the compression is released.
  • the first and second members 310 traverse each side of the ramp member 345 when transitioning from the trigger unlocked position to the trigger locked position and back to the trigger unlocked position.
  • Compression of the trigger 140 then causes the distal ends of the first and second members 310 and 312 to move in the directions shown by arrows 342 and 364, but due to the displacement of the locking member 144 in the direction of arrow 354, the first and second members 310 and 312 do not contact the locking head 146 and no locking of the trigger 140 relative to the main body 110 is accomplished by compression of the trigger 140.
  • no wear or stress is exerted on the first and second members 310 and 312 when the trigger 140 is compressed while the locking member 144 is in the unlocked state.
  • the locking member 144 is transitioned to the unlocked state from the locked state, while the trigger 140 is locked, then there is no wear or stress on the first and second members 310 and 312 when the locking member 144 is released and returned to a rest state.
  • the distal ends of the first and second members 310 and 312 are held at the rest surface 360 and are spread apart from each other by the rest surface 360 being disposed between them. Movement of the locking member 144 to the unlocked state will move the distal ends of the first and second members 310 and 312 off of the rest surface 360 in the direction of arrow 354 and allow them to collapse together.
  • the first and second members 310 and 312 may move in the direction of arrow 364 without contacting the ramp member 345.
  • the locking member 144 can be moved to the unlocked position from the locked state of the trigger 140 to release the trigger 140 and also immediately reduce the stress and avoid wear on the first and second members 310 and 312 of the locking member 144 as the trigger 140 returns to the unlocked and extended position.
  • the entire locking mechanism may therefore encounter less wear and stress, so that the mechanism lasts longer.
  • the ramp member 345 may act as a first guide surface configured to interface with the locking member when the trigger 140 transitions from the unlocked state to the locked state
  • the ejection ramp 362 may act as a second guide surface to interface with the locking member 144 when the trigger 140 transitions from the locked state to the unlocked state.
  • the first guide surface and the second guide surface may each bisected by a support member (i.e., the engagement surface 340 for the ramp member 345 and the ramp base member 365 for the ejection ramp 362) that extends in a plane substantially perpendicular to the axis (and therefore also the longitudinal centerline of the trigger 140 and/or the handle portion 119) of the handle portion 119.
  • a water application device may be provided in accordance with some example embodiments.
  • the water application device may include a main body graspable along a handle portion thereof by an operator and an operable member.
  • the main body may house a flow control assembly configured to enable the device to execute a control function relative to flow of water through the device.
  • the operable member may be pivotally attached to the main body to interface with the flow control assembly to alternately provide flow when pivoted to a compressed position and stop flow when pivoted to an extended position.
  • the operable member may have a length extending substantially parallel to an axis of the handle portion.
  • One of the operable member or the main body may include a locking member.
  • the locking member may be configured to interface with a locking head disposed at the other of the operable member or the main body.
  • the locking member may have a locked position and an unlocked position defined by movement of the locking member relative to the locking head. Compression of the operable member with the locking member in the locked position may transition the operable member alternately between a locked state and an unlocked state with each compression. The operable member may remain in the unlocked state when the locking member is in the unlocked position regardless of the compression of the operable member and the locking member may not contact the locking head when the locking member is in the unlocked position.
  • the device employing the features of some embodiments may include additional features that may be optionally added either alone or in combination with each other.
  • (1) (4) the locking member may be disposed in a receiving slot formed in the operable member.
  • the receiving slot may pass from the first surface entirely through the operable member to enable an engagement portion of the locking member to contact the locking head fixed relative to the main body based on a position of the locking member.

  • the first and second members may extend toward the main body and may be aligned with each other in a line substantially parallel with the axis of the handle portion.
  • the first and second members may each include protrusions extending toward each other to define a locking gap bounded by the first and second members, the protrusions, and a portion of the locking member that is contacted by the operator to move the locking member between the locked position and the unlocked position.
  • first and second members are configured to be deflected out of a rest state in which the first and second members extend substantially perpendicular to the axis of the handle portion during compression of the operable member based on contact with the locking head and are configured to return to the rest state after each compression such that the first and second members are returned to the rest state in both the locked state and the unlocked state of the operable member. Additionally or alternatively, the first and second members may be deflected to pass along a first side of the locking head when transitioning from the unlocked state to the locked state of the operable member, and pass along a second side of the locking head when transitioning from the locked state to the unlocked state of the operable member.
  • the locking member may be snap fit into slidable engagement with the receiving slot.
  • the locking head may include a first guide surface configured to interface with the locking member when transitioning from the unlocked state to the locked state of the operable member, and a second guide surface, different from the first guide surface, to interface with the locking member when transitioning from the locked state to the unlocked state of the operable member.
  • the first guide surface and the second guide surface may each be bisected by a support member that extends in a plane substantially perpendicular to the axis of the handle portion.
