Abstract

A garden sprinkler hose generally triangular in transverse cross section, comprising two firm relatively thick walls joined at one of their longitudinal edges, and a third relatively thin and flexible wall joined at its longitudinal edges to the two thicker walls, the third wall being provided with sprinkler holes. The hose is designed to rest on one of its thick walls. Water pressure in the hose causes the thin flexible wall to curve outwardly, the degree of curvature depending on the pressure in the hose, thereby to control and vary the area which receives water through the aperture in the flexible wall.

INVENTOR. HEINO BOHLMAN BY mi.

ATTORN E Y GARDEN SPRINKLER HOSE This invention relates to a garden sprinkler hose designed to deliver water to restricted areas and in selected directions. The extent of the area to which water is delivered by the hose is controlled by the water pressure.

The objects of the invention are achieved by providing a hose construction which is generally triangular in transverse cross section, two of its three wall sections being relatively firm and thicker than its third wall section which is relatively thin and flexible. Only the flexible wall is provided with apertures for passage of water out of the hose. This arrangement permits either of the imperforate, firm relatively thick walls to serve as a base on which the hose may rest, while the flexible wall responds to water pressure in the hose by curving outwardly, causing the water streams to flow in predetermined directions and to cover lawn and garden areas to a selected extent.

The hose may be placed adjacent a wall or sidewalk edge, with its flexible wall facing away from the wall or walk edge, to deliver water without waste to cover an area of selected width.

In the drawings:

FIG. 1 is an isometric view of a portion of a garden sprinkler hose embodying the invention.

FIG. 2 is a transverse sectional view showing the hose as it appears when delivering water streams in response to limited water pressure in the hose.

FIG. 3 is a view similar to FIG. 2 showing the hose as it appears when delivering water streams in response to increased water pressure in the hose as compared to FIG. 2.

In the embodiment of the invention shown in the drawings, the hose comprises two imperforate, relatively firm and thick wall sections 11 and 12, either of which may provide a base on which the hose rests in use. The walls 11 and 12 are joined together at one of their longitudinal edges to extend at divergent angles. The other longitudinal edges of the walls 11 and 12 are joined to a relatively thin and flexible wall 13 provided with apertures l4 for passage of water out of the hose.

The junctions between each of the walls 1 l and 12 and the flexible wall 13 are curved continuations of the flexible wall which merge into the thicker walls 1 l and 12 as indicated at 15.

The flexible wall 13 responds to the water pressure in the hose by curving outwardly to varying degrees, as illustrated in FIG. 2 where the water pressure is less than maximum, and in FIG. 3 where the water pressure has been increased as compared to FIG. 2. Thus the width of the area covered by the water is less in FIG. 2 than in FIG. 3, due to the degree of curvature of the wall 13.

By placing the hose on either of its walls, 11 or 12, adjacent a wall or walk or patio edge, the water is directed away from the not-to-be watered area, and the extent of the area to be watered can be controlled as to direction and width.

The hose may be made of rubber or any other suitable material which permits automatic curvature of the apertured wall in response to water pressure. The walls preferably are molded or formed integrally.

I claim:

l. A garden sprinkler hose which is triangular in transverse cross section com rising I a. two relatively firm thlc lmperforate walls oined together at one of their longitudinal edges and extending in divergent directions, and

b. a relatively thin and flexible wall provided with apertures and joined at its longitudinal edges to said relatively thick walls, said flexible wall curving outwardly in response to water pressure in the hose and delivering water streams through said apertures to cover areas of selected width controlled by said water pressure, said flexible wall being joined to the relatively firm and thicker walls by curved joints thinner than the firm walls and integral with said other walls, either of the two relatively firm and thick walls constituting the base on which the hose rests in use and both being imperforate, whereby water streams flow only from the flexible perforated wall to only a selected one of two sides of the hose, the degree of flexing of the flexible wall and width of the area sprinkled being controlled by water pressure in the hose.

Claims

1. A garden sprinkler hose which is triangular in transverse cross section comprising a. two relatively firm thick imperforate walls joined together at one of their longitudinal edges and extending in divergent directions, and b. a relatively thin and flexible wall provided with apertures and joined at its longitudinal edges to said relatively thick walls, said flexible wall curving outwardly in response to water pressure in the hose and delivering water streams through said apertures to cover areas of selected width controlled by said water pressure, said flexible wall being joined to the relatively firm and thicker walls by curved joints thinner than the firm walls and integral with said other walls, either of the two relatively firm and thick walls constituting the base on which the hose rests in use and both being imperforate, whereby water streams flow only from the flexible perforated wall to only a selected one of two sides of the hose, the degree of flexing of the flexible wall and width of the area sprinkled being controlled by water pressure in the hose.
