Abstract

A watering device for plants which comprises horizontal parallel pivot rods and a plant container which is balanced on one of the horizontal pivot rods by an adjusting weight member slidably disposed at the other horizontal pivot rod, and a water reservoir tank is operatively associated with the plant container so that as the plant container becomes lighter as to a loss of water. The adjusting weight member operatively associated with the plant container actuates a valve in the water reservoir tank through a transfer member mounted to third one of horizontal parallel pivot rods and transfer water from the water reservoir tank to the plant container until a balance is again achieved, and when the balance is reached, the valve in the water tank is again closed.

Claims

1. An automatic watering device for plants adapted to suspended from a wall or ceiling which comprises:

horizontal pivot rods composed of a first horizontal pivot rod having a plurality of apertures disposed at the right end portion thereof, a second horizontal pivot rod, and a third horizontal pivot rod having a plurality of slots disposed at the end portion thereof, said horizontal pivot rods being pivotably provided at one portion thereof with supporting members for supporting the horizontal pivot rods, said supporting members being provided with a fixed supporting plate for limiting the pivotal action of the horizontal pivot rods,

an adjusting weight member hanging from one of said slots disposed at the other end portion of the third horizontal pivot rod, said adjusting weight member and a plant container hanging said first horizontal pivot rod being positioned in said slots to balance each other through said second horizontal pivot rod,

a water reservoir tank adapted to contain a supply of water, said water reservoir tank being attached to said fixed supporting plate for mounting said supporting members to said fixed supporting plate, said water reservoir tank containing transfer means for conveying water from said water reservoir tank to said plant container, and

valve means operatively associated with said transfer means for controlling the conveyance of water from said water reservoir tank to said plant container, said valve means being connected to said second horizontal pivot rod through connecting means, said connecting means including a connecting member connected to the end of the second horizontal pivot rod and an adjusting connector operatively connected to a wire which passes through a roller disposed at the top portion of said water reservoir tank and contents to said valve means whereby, upon the loss of water from the plan container, the horizontal pivot rods are caused to pivot, respectively, which opens the valve means permitting water to flow through the transfer means to the plant container until the balance is re-established causing the valve to close.

2. The automatic watering device of claim 1, wherein the transfer means is a drain hole disposed in the side bottom of the water reservoir tank and a drain pipe disposed in a drain hole gasket which is fixed within said drain hole for extending from said drain hole to the plant container, and the valve means being adapted to open and close said drain pipe depending on the balance portion of the horizontal pivot rods.

3. The automatic watering device of claim 1, wherein the valve means pivotably connected to said drain hole gasket includes a rod which is provided with a valve attached to one end portion and a weight member attached to the other end portion for closing said drain hole of the water reservoir tank, utilizing the valve means, by gravity of the weight member.

4. The automatic watering device of claim 1, wherein the connecting member has a U-shaped configuration and is provided with a pair of apertures disposed in the end portions thereof.

5. The automatic watering device of claim 1, wherein the adjusting connector includes a plurality of light slots for operatively engaging said connecting member.
