Abstract

A watering and shading device for at least one plant is disclosed. The device comprises an elongated substantially hollow shaft. A top end of the shaft terminates in a preferably flared funnel-shaped opening for receiving water, and a bottom end terminates in a soil-penetrating spike for inserting into soil. The spike includes at least one aperture therein for allowing water to pass from the inside of the hollow shaft therethrough. The device also includes a shading umbrella that comprises at least one non-transparent panel attached at one portion thereof to a shaft attachment means. The umbrella may be selectively placed in a deployed position or a collapsed position at a selected height along the shaft. The shaft includes a valve mechanism therein proximate the bottom end controlled by a moisture detection means for regulating the position of the valve mechanism based upon the soil moisture level. At least one solar-powered lantern may be included, fixed to the shading structure, and activated upon a photovoltaic cell detecting darkening conditions.

Claims

1. A plant watering and shading device comprising:

an elongated substantially hollow shaft having a top end and a bottom end, the top end terminating in an opening for receiving water, the bottom end terminating in a soil-penetrating spike, the spike including at least one aperture therein for allowing water to pass from the inside of the hollow shaft therethrough;

a shading structure comprising at least one non-transparent panel attached at one portion thereof to a shaft attachment means;

whereby with the bottom end of the shaft inserted into soil proximate a plant, water may be introduced into the top end of the shaft for dispensing through the spike to wet the soil, and the shading structure may be positioned to provide shade to the plant.

2. The plant watering and shading device of claim 1 wherein the shading structure is in the form of an umbrella, the umbrella capable of being selectively placed in a deployed position or a collapsed position around the shaft, the shaft attachment means being a first annular collar having an aperture therethrough for receiving the shaft, the first collar being fixed to the shaft.

3. The plant watering and shading device of claim 2 wherein the first collar includes a shaft locking means for selectively fixing the position of the first collar on the shaft.

4. The plant watering and shading device of claim 3 wherein the umbrella additionally includes a second collar slidable on the shaft independently from the first collar, the second shaft attached to an umbrella deployment mechanism for selectively deploying or collapsing the umbrella, the second collar having a shaft locking means for fixing the position of the second collar on the shaft.

5. The plant watering and shading device of claim 1 further including a valve mechanism within the hollow shaft proximate the bottom end thereof, the valve mechanism in a closed position preventing water in the shaft from reaching the bottom end of the shaft, and the valve mechanism in an open position allow water to flow from the shaft to the bottom end of the shaft.

6. The plant watering and shading device of claim 5 wherein the valve mechanism is a ball valve having a buoyant ball captured within the bottom end of the shaft, and a seal within the shaft adapted to receive the ball against a lower side thereof to close the valve.

7. The plant watering and shading device of claim 5 further including a moisture detection means in electronic communication with a control circuit, the control circuit powered by a power source and regulating the position of the valve mechanism based upon electronic signals received from the moisture detection means.

8. The plant water and shading device of claim 7 wherein the moisture detection means is an elongated electric moisture probe adapted to be inserted into the soil, the probe having at least one flexible conductor for electrically connecting the probe to the control circuit.

9. The plant watering and shading device of claim 1 wherein the at least one panel further includes at least one solar cell, each solar cell for charging a battery of at least one lantern, each lantern being fixed to the shading structure and connected to a lamp circuit that supplies power from the battery to a light emitting means of the lantern when a photovoltaic sensor of the lamp circuit detects little ambient light.

10. The plant watering and shading device of claim 1 further including a cover adapted for attaching to the funnel-shaped opening at the top end of the shaft for preventing water from filling the shaft.

11. The plant watering and shading device of claim 1 further including a shaft clamping means fixed proximate the bottom end of the shaft, the shaft clamping means adapted for clamping and retaining the device onto the rim of a planting pot.

12. The plant watering and shading device of claim 1 wherein the shaft includes an upper shaft having the top end and a lower shaft having the bottom end, the lower shaft having an outside dimension of less than an inside dimension of the upper shaft, such that the lower shaft may be co-axially inserted into the upper shaft, an elastomeric gasket being further included to prevent water from leaking between the upper and lower shafts, whereby the overall height of the shaft may be selectively adjusted by sliding the lower shaft a desired distance into the upper shaft.

13. The plant watering and shading device of claim 12 wherein the lower shaft further includes a water-proof, flexible, collapsible portion fixed to the upper shaft whereby water is prevented from leaking from the lower shaft into the upper shaft.
