Abstract

Abstract A container for plants is rotated as water is evaporated and respirated therefrom due to the interaction between a compression spring and linear-to-rotary motion mechanism. The compression spring is disposed between the container and a stop on a support shaft suspended from above wherein the support shaft has a spiral portion thereon and the container has a slot for receiving the spiral portion. As water evaporates, weight on the compression spring is reduced and the container rises upwardly on the shaft in relation to the stop on the shaft. As the container rises, it rotates slowly. In an alternative embodiment, the shaft is rigidly fixed to a base upon which the container rests and the container includes a soil containing pot which may move relative to the base. The compression spring is disposed between a stop on the shaft and the soil containing pot to bias the pot upwardly when there is no water therein so as to raise and rotate the pot with the linear-to-rotary motion mechanism as the water evaporates.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 122 words
A horticulture device for rotating a plant, comprising; a container means for holding the plant and water for the plant; means for supporting the container; motion converting means disposed between the container means and the support means for converting linear motion to rotary motion; compression spring means disposed between the container means and support means for compression when gravitational force is applied to the container means by adding water to the container means, whereby as the water is lost from the container means the compression spring means moves the container means upward relative to the support means, said motion converting means being connected to rotate the container means as the spring means expands due to loss of water from said container means.
Claim 2
Dependent Claim 122 words
A horticulture device for rotating a plant, comprising; a container means for holding the plant and water for the plant; means for supporting the container; motion converting means disposed between the container means and the support means for converting linear motion to rotary motion; compression spring means disposed between the container means and support means for compression when gravitational force is applied to the container means by adding water to the container means, whereby as the water is lost from the container means the compression spring means moves the container means upward relative to the support means, said motion converting means being connected to rotate the container means as the spring means expands due to loss of water from said container means.
Claim 3
Dependent Claim 31 words
The horticulture device of claim 1 wherein the motion converting means comprises a spiral portion on the support means and a slot within the container means for receiving the spiral portion.
Claim 4
Dependent Claim 17 words
The horticulture device of claim 2 wherein the support means includes a hook for hanging the device.
Claim 5
Dependent Claim 43 words
The horticulture device of claim 2 wherein the support means includes a base upon which the device rests and wherein the compression spring means urges the container means away from the base to rotate the container means as water evaporates and transpirates therefrom.
Claim 6
Dependent Claim 62 words
The horticulture device of claim 1, 2, 3, or 4 wherein the container includes a hollow pylon extending upwardly therein and having a hortizontal top surface, wherein the horizontal top surface is abutted by one end of the compression spring and wherein the support means includes a horizontal surface fixed thereon which is abutted by the other end of the compression spring.
