DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to a manual scrubbing device.
BRIEF SUMMARY OF THE INVENTION
A scouring device for manual use has a support formed by folding a pair of substantially identical longitudinal parts about a central hinge to form a pad mounting portion and a handle portion and a pad adapted to be mounted on the support.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a top view of the scouring device of the instant invention where the two symmetrical longitudinal parts forming the support have not been folded about their axis of symmetry;
FIG. 2 is a side view of the support and pad of FIG. 1;
FIG. 3 is a side view similar to FIG. 2 where the support has been folded about its axis of symmetry and the two pieces forming the handle section have been snapped together;
FIG. 3a is a sectional view along the line 3a--3a of FIG. 3;
FIG. 4 is a perspective view of a sewn pad adapted to be mounted on the support illustrated in FIGS. 1 through 3;
FIG. 5 is a perspective view of a tubular pad adapted to be mounted on the support illustrated in FIGS. 1 through 3; and
FIG. 6 is a perspective view of a parallelepiped pad adapted to be mounted on the support illustrated in FIGS. 1 through 3.
DETAILED DESCRIPTION OF THE INVENTION
The scouring device of the instant invention is comprised of two elements. The first is a support and the second is a sliding pad. The support shown in FIGS. 1 and 2 consists of two symmetrical longitudinal parts (A) and (B), preferably identical which can be arranged to extend lengthwise from a central hinge which folds along the device's axis of symmetry (p). The hinge has a width (n).
Each of the longitudinal parts (A) and (B) has a first parallelepiped element (C) and (D) respectively which is bent at a fixed obtuse angle (.alpha.), with a second flat parallelepiped element (C') and (D'). The length of the second elements (C') and (D') may be different from or equal to that of the first elements In terms of their respective lengths, the length of (C) plus the length of (C') equals the length of (D) plus the length of (D'). The support further consists of a pair of third elements (M1) and (M2) where (M1) is formed of a longitudinal section extending in a straight line from previous section (C') and (M2) is formed of a longitudinal section which extends in a straight line from previous section (D'). The cross section of third elements (M1) and (M2) is generally semicircular in shape so that by rotation of 180.degree. about the center hinge defined at fold line (P), third elements (M1) and (M2) can be joined together. See FIGS. 3 and 3a. Elements (M1) and (M2) are snapped longitudinally in place by means of a center longitudinal rail (r) formed in and extending from element (M2) which through manual pressure, penetrates a central longitudinal cavity (c) which faces rail (r) and is formed within the volume defined by third element (M1). The length of cavity (c) is slightly greater than the length of rail (r). The depth of cavity (c) is slightly greater than the height of rail (r). The cross sections of rail (r) and cavity (c) are isosceles trapezoids of identical slope. The male rail section (r) is slightly sturdier than the female section cavity (c) to ensure good closure with only slight pressure.
Once third elements (1) and (2) have been joined, they form the handle of the scouring device. Whenever it is necessary to separate them, they can be spread apart through the application of two gentle radial forces in opposing directions acting on corresponding grips (k1) and (k2) respectively, preferably arranged in symmetric recesses at the ends of elements (M1) and (M2) illustrated in FIG. 3.
The above description relates only to the version of the device where parts (A) and (B) are identical, although it is obvious that other useful configurations of parts (A) and (B) exist with different respective values for first elements (C) and (D) and second elements (C') and (D') so long as angle (.alpha.) and angle (.beta.) remain within operative val
