Filed:

May 27, 2011

Appl. No.:

13/117999

Inventors:

Raul Castro - Oceanside CA, US

International Classification:

F16L 11/00

US Classification:

138121, 138122, 138129, 138118

Abstract:

An expandable hose is provided which will expand to an extended length from a collapsed length and back again. The hose has a sidewall formed of a spirally wound flexible member which defines an axial passageway surrounding a center axis of said hose. Both side edges of the flexible member in the spirally wound position are engaged to a cap member which provides a skeletal structure to maintain the axial passageway open and to bias the hose back to a collapsed length from the extended length. A fold formed in the spirally wound flexible member allows for increased distance between the two side edges and an increased maximum extended length.

Abstract:

An expandable hose is provided formed of a sidewall formed of a spirally wound flexible member which defines an axial passageway surrounding a center axis of the formed hose.

Abstract:

A triple articulating security device for use with a door, such as a house door having a hinged side and a latch (opening) side device holds a door in a closed (security) position or in a partially open (viewing) position. The security device generally comprises a pair of mounting brackets and a bar. The mounting brackets mount, preferably on opposite sides of the door. The bar comprises a viewing portion pivotally mounted to the latch-side bracket, an elongated telescoping portion pivotally mounted to the hinge-side bracket, a pivot pivotally joining their inner ends, a locking mechanism for selectively locking the pivot. The bar is reconfigurable from a securing position, wherein the door is closed and the bar extends substantially linearly between the brackets and the bar prevents the door from opening inward to a viewing position, wherein the viewing portion and the telescoping portion pivot about the pivot such that their inner ends may be swung away from the door such that the door may be partially opened for viewing between the latch edge of the door and the latch side of the frame. A door restraining spacer of adjustable length attached to the viewing portion of the bar spans between the bar and the inner side of the closed door.
