I. Field of the Present Invention
The present invention relates to a self watering legged sheet with a plurality of leg, more particularly to a self watering legged sheet with side walls, and further particularly to a self watering legged sheet with connection part on side of the sheet.
II. Description of the Prior Art
The European method for roof greening (
The present invention relates to a self watering legged sheet with a plurality of leg, more particularly to a self watering legged sheet with side walls, and further particularly to a self watering legged sheet with connection part on side of the sheet.
The present invention discloses a self watering legged sheet. The self watering legged sheet can be used in different area, such as roof, greenhouse, nursery field, concrete surface, and does not needs multiple layer, also having a much high water reserve capacity etc.
In one embodiment of the present invention, a self watering legged sheet includes a flat board, a plurality of leg connecting to the flat board at a first end of the leg, means they are in two pieces, or the legs extending downwardly from the flat board, means they are in one piece. The legs have a side wall and a fluid conduit between the first end and second end of the leg for fluid communication while it is in use.
Further in one embodiment, the legs have a bottom wall at second end, at least one hole disposed on the bottom wall or on the lower side wall for fluid communication to out side of the leg.
Still in one embodiment, a plurality of air vent hole disposed on the flat board.
Yet in one embodiment, the sheet includes connection parts on edges of the flat board.
Further in one embodiment, a side wall extending upwardly from or connectinig to the edge of the flat board.
Still in one embodiment, the connection parts disposed on the up edge of the side wall.
Yet in one embodiment, the connection part is movable. While the movable connection part be used on flat board, there are receive holes only on edge of the sheet. While the movable connection part be used on side walls of the flat board, it directly clipped two side walls of two sheet together. So that, no receive holes are needed.
Still in one embodiment, shape of the leg can be vary.
One advantage of the above inventions is that the root of the plant placed on the sheet is prevented/limited from extending to a fluid holding area. So that the root of the plant is not easily damaged by excessive fluid, the root fully contacts soil and absorbs nutrition completely, then the plant grows much healthy. Further advantage is that the sheet has a much large fluid holding space, the water holding space is created by the legs while it is in use. So that it is not necessary to nurse the plant very frequently, and huge rain water can be utilized. Furthermore, the sheet can be easily applied to flat roof, slope roof, concrete surface, greenhouse, nursery field, etc.
These and various other advantages and features of novelty which characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages and objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying descriptive matter, in which there is illustrated and described a preferred embodiment of the inventions.
A better understanding of the construction and operational characteristics of a preferred embodiments can be realized from a reading of the following detailed description, especially in light of the accompanying drawings in which like reference numerals in the several views generally refer to corresponding parts.
The present invention relates to a self watering legged sheet with a plurality of leg, more particularly to a self watering legged sheet with side walls, and furthermore particularly to a self watering legged sheet with connection parts.
In the following description of the exemplary embodiment, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration the specific embodiment in which the invention may be practiced. It is to be understood that other embodiments may be utilized as structural changes may be made without departing from the scope of the present invention.
Referring now to
Further in
Furthermore in
The present invention can also be applied on concrete surface such as wayside, or in greenhouse and nursery field to reduce water lose and environment problems.
