Filed:

Jan 12, 2001

Appl. No.:

09/759065

Inventors:

Christopher Laux - Hamilton OH
David Hunt - Cincinnati OH
Robert Roth - Cincinnati OH

Assignee:

O-Cedar Brands, Inc. - Springfield OH

International Classification:

A47L 13142

US Classification:

151202, 151201

Abstract:

A mop including a mop handle and a mop head located at one end of the handle and including a plurality of flexible strands defining a mop body. A sleeve is positioned on the mop handle and is supported for slidable movement in an axial direction parallel to the handle, and is further supported for rotatable movement relative to the handle. A lower end of the sleeve is provided with engagement portions defined by slots for engaging and gripping the strands of the mop body to facilitate twisting of the mop body by the sleeve. In addition, a ratchet and pawl mechanism is provided by cooperating portions of the mop body and sleeve to limit rotation of the sleeve to a single direction during a wringing operation.

International Classification:

A47L 13142

US Classification:

151202, 151201, 151161, 151191

Abstract:

A self-wringing ratchet mop including an elongated handle, a mop head having mop strands supported on the handle, and a wringing mechanism for wringing the mop strands. The wringing mechanism includes a sleeve attached to the mop strands and supported for longitudinal and rotational movement relative to the handle. The handle includes a first ratchet portion formed by teeth and the sleeve includes a second ratchet portion formed by pawl members for engaging the first ratchet portion to permit the sleeve to rotate in a first direction and prevent rotation in a second, opposite direction. The pawl members are supported on a deformable resilient ring wherein deformation of the ring causes the pawl members to disengage from the first ratchet portion and permit rotation of the sleeve in the second direction.

G01B 11/24

US Classification:

3562411, 356601

Abstract:

The inner surface of an underground tunnel defining structure, such as a culvert or pipe, is measured by apparatus including a portable hand held battery powered laser unit releasably attached to a rotor disk supported within the tunnel by an adjustable stand or tripod for rotation on a generally horizontal axis. The disk has peripherally spaced notches which receive a spring-biased latch member for positioning the disk and laser unit at predetermined angular positions about the axis. The laser unit emits a laser beam to a target on the inner surface of the structure and displays on the unit a precision distance reading from the laser unit to the target. The distance reading for each target is entered in a chart for comparison with a prior measurement reading to indicate changes in the shape or profile of the inner surface.
