In particular, the present invention relates to an activity system that includes a supply unit or station and an activity unit that can be used with the supply unit. The supply unit is configured to supply a fluid to the activity unit station when a user engages the activity unit with the supply unit.
The present invention relates to an activity system that can be used with a supply of fluid, such as water. In particular, the present invention relates to an activity system that includes a supply unit or station and an activity unit that can be used with the supply unit. The supply unit is configured to supply a fluid to the activity unit when a user engages the activity unit with the supply unit.
BACKGROUND OF THE INVENTIONChildren often enjoy playing with a fluid, such as water. Most children do not share their parents' concerns over wasting water or controlling the use of water. Parents try to balance these concerns with their desire to allow children to play as independently as possible. On a warm or hot day, water games can provide a fun and soothing outdoor activity. Typically, water games often include or utilize water toys, such as water fillable toys (e.g., buckets, squirt guns, etc.) or water dispensing toys (e.g., water slides, sprinklers, etc.). The process of supplying water to such toys can be difficult for small children and can lead to significant spillage.
Typically, parents provide a supply of water, such as a hose connected to a water supply from a house, to a specified play area in a yard where children can enjoy various activities. The hose generally extends between the specified play area and a faucet with a shut-off valve. Excited and distracted children typically consider it inconvenient to travel back and forth between the valve and the play area to turn off the supply of water. This reduces the likelihood that a child will turn off the flow of water at the valve as required to minimize waste.
Even if a valve is provided at the downstream end of a hose, waste and spillage of water is still likely to occur, especially by very young children. Usually, children must hold the hose and direct the water toward a particular container (e.g., filling a squirt gun with a garden hose spray nozzle), which can be very difficult.
Thus, there is a need to develop an activity system that can be conveniently and easily used with a water supply. In addition, there is a need to provide an easy way for young children to provide water to and use water with an activity unit or mechanism. Finally, there is a need for a water supply system that easily supplies water to an activity unit without excessive water waste.
SUMMARY OF THE INVENTIONThe present invention relates to an activity system that can be used with a supply of fluid, such as water. In one embodiment, the activity system includes a supply unit that is configured to function as a source of water. The supply unit can be coupled to an external source of water, such as via a hose. The activity system also includes an activity unit that can be used by a child during play. The activity unit is configured so that it is engageable with the supply unit so that water from the supply unit can be provided to the activity unit. In one embodiment, the activity unit can be a container, such as a bucket or a squirt gun storage compartment. In another embodiment, the activity unit can be a more interactive unit, such as a spray-type activity unit like a sprinkler or a sprayer. The container is configured to contain water and the spray-type activity unit is configured to receive and disperse water continuously.
In one embodiment, the supply unit includes a housing with a passageway passing through the housing. Water enters the passageway through an inlet port or opening and is discharged from the passageway through an outlet port or opening. Proximate to the inlet port of the supply unit is a connector or coupler that is configured to be connected to a water supply, such as a hose or tubing.
In one embodiment, the supply unit housing includes a valve at the outlet port of the supply unit. The valve controls the flow of water through the passageway and through the outlet port. The valve includes a seat and a valve body that is movable relative to the seat between an opened position in which water flows through the valve and a closed position in which water is prevented from flowing through the valve. The seat can be configured to limit movement of the valve body in a particular direction. In one alternative embodiment, the valve may include a biasing mechanism, such as a spring, that is disposed to bias or force the valve body into engagement with the seat of the valve. Accordingly, in that embodiment, the valve of the supply unit is initially in its closed position.
When an external force is applied to the valve body, the valve body moves from its closed position in contact with the seat to its opened position spaced apart from the seat, provided that the external force is sufficient to overcome the pressure of the fluid on the other side of the valve body. Thus, when sufficient external force is applied by an external object, the valve body moves to its opened position and water can flow through the valve of the supply unit.
In one embodiment, the activity unit includes a body defining a receptacle. The body includes an inlet port that is in fluidic communication with the receptacle. In other words, the activity unit can be filled with a fluid, such as water, that passes through the inlet port of the body and into the receptacle where the water can be retained. In one embodiment, the activity unit includes a valve at the inlet port. The valve controls the flow of water through the inlet port. The valve includes a seat and a valve body that is movable relative to the seat between an opened position in which water can flow through the valve out of the activity unit and a closed position in which water is prevented from flowing through the valve and out of the activity unit. The valve also includes a biasing mechanism, such as a spring, that is disposed to bias or force the valve body into engagement with the seat of the valve. The valve of the activity unit is initially in its closed position and is configured to retain water in the activity unit.
When an external force is applied to the valve body of the activity unit, the valve body moves to is opened position. To transfer water from the supply unit to the activity unit, the outlet port of the supply unit must be aligned with the inlet port of the activity unit and the valves of the supply unit and the activity unit must be open at the same time. Thus, the valve bodies of the supply unit and the activity unit must be moved from their unbiased, closed positions to their opened positions to permit the flow of water through the valves.
In one embodiment, the activity unit can be used to apply the external force to the valve of the supply unit to move the valve body of the supply unit to its opened position. The valve body of the activity unit is configured so that it can be used to contact the valve body of the supply unit. As a result, the force applied by each valve body on the other valve body results in the valve bodies moving from their closed positions to their opened positions. In one embodiment, such movement may occur substantially simultaneously. With both of the valves open, water can flow from the supply unit into the activity unit. In different embodiments, the opening of the valves is determined by the characteristics of the biasing mechanism.
In another embodiment, the sprayer-type activity unit can be coupled to the supply unit using a quick-release locking mechanism. When the sprayer-type activity unit is coupled to the supply unit, a portion of the activity unit engages the valve of the supply unit and opens the valve so water can flow therethrough. The quick-release locking mechanism can be manipulated by a user to couple and decouple the activity unit easily.
In one embodiment, the sprayer-type activity unit includes a base and a sprayer or spraying unit. Engaging the base to the supply unit causes the valve of the supply unit to be opened and water can flow through the outlet port of the supply unit to the activity unit. When the base is decoupled from the supply unit, the valve body returns to its closed position and water does not flow through the outlet port of the supply unit. In one implementation, the sprayer-type activity unit can be a foot pedal activated sprayer.

Each of the valves 28 and 36 must be in its opened position for water to be delivered from supply unit 20 to activity unit 30 through ports 26 and 34. In one embodiment, valve 28 requires a force in an upstream direction and valve 36 requires a force in a downstream direction. Each of the valves 28 and 36 can be used to apply the necessary force to the other of the valves 28 and 36. In other words, valve 28 can be pressed against valve 36 and the resulting force causes both of the valves 28 and 36 to open. When the valves 28 and 36 are opened, water can flow through the outlet port 26 and the inlet port 34.

In an alternative embodiment, the valve 600 does not include a biasing mechanism 660. In that embodiment, the valve body 601 has a sufficient weight so that the valve body 601 is moved to its normally closed position by gravity in lieu of biasing mechanism 660.
Referring to
When the externally applied force is removed from the valve 600, the biasing mechanism 660 forces the valve body 601 downwardly along the direction of arrow “F” in
Referring to
The operating structures of valve 240 and valve 600 provide a simple method of opening both valves at the same time. Valve 240 requires an opening force in the upstream direction and the valve 600 requires an opening force in an opposite downstream direction. Since valves 240 and 600 require opposing opening forces, the valves 240 and 600 can both be opened by bringing a portion of valve 240 (such as valve body 300) into engagement with a portion of valve 600 (such as valve body 601). Therefore, opening both valves 240 and 600 can be accomplished by forcing valve body 300 into engagement with valve body 601, thereby providing the external force needed to open the other corresponding valve.
As shown in
When the container 500 is placed onto the supply unit 200, the valve 600, including valve body 601, engages the upper end of the valve body 300. As valve body 601 engages the valve body 300, valve body 601 moves along the direction of arrow “K” toward its opened position 608. As container 500 is pressed against the supply unit 200, the movement of the flange 612 upwardly is limited by the seat 550 (see
When the valve 600 is in its opened position, fluid flows in along the spaces or voids 324 in the valve body 300. The voids 324 are recesses that allow fluid to flow between the valve body 300 and the inner surfaces or walls defining the inlet port for the container 500 when the valve body 300 is unseated. When container 500 is disengaged from supply unit 200, valve body 300 returns to its closed position and valve 600 returns to its closed position. When valve 600 is closed, fluid in the receptacle 522 of the container 500 cannot escape through the port. A child can transport or carry the container 500 and the fluid therein to participate in a fun activity.
