Abstract
A trowel for cleaning wall and floor tiles of grout, having a handle affixed to a base place to which is adhered a soft pad, wherein the lower surface of the base plate and the upper surface of the pad have complimentary engaging-engaging strips engageable and disengageable one strip with another. Disengagement of the strips allows for the pad to be discarded when required and replaced with another pad. This negates the need to discard the full trowel with a significant saving in monetary cost and inconvenience.
Description
GROUTING TROWEL
FIELD OF THE INVENTION
This invention relates to a grouting trowel, particularly for manual use, and having a foam pad, in the cleaning of freshly laid floor or wall tiles, particularly, ceramic tiles.
BACKGROUND OF THE INVENTION
The process of laying tiles, particularly ceramic tiles on a flat wall or floor surface typically involves the spreading of an adhesive cement, known as a "thin set"
on the surface with a trowel.
One form of trowel has a handle affixed to a rectangular thin metal plate having indentations on each of the two longitudinal edges for spreading out the "thin set", to a desired thickness intermittent of the area covered to leave a roughened uneven surface.
An alternative trowel has a handle and rectangular metal plate of similar dimensions affixed to a rectangular non-abrasive, rubber foam pad of the same surface area as the metal plate and a thickness of about lcm. This pad trowel may be used in the same manner as the metal trowel in spreading thin set adhesive on the surface.
Further, once the tiles are laid out on the surface, grout is spread on and between the tiles by the trowel and the excess subsequently removed. Since the grout contains rough particulate filler, although the pad trowel is more gentle and minimize abrasion of the tile surface than the metal trowel surface, the soft pad suffers from being worn down by the grout particles. Such a prior art grout trowel with a pad, generally, only last for between 30-40 hrs.
of utilization, before a replacement trowel is needed and the current trowel discarded.
Further, uneven wear of the pad particularly at its edges and corners can cause damage to a tile by a metal plate corner or edge.
Although there is a need for a more suitable soft pad material with a more longer acting life, until one is available, such full grout trowels will continue to be "prematurally"
discarded.
SUMMARY OF THE INVENTION
The invention provides a trowel for cleaning wall and floor tiles of grout, having a handle affixed to a base place to which is adhered a soft pad, wherein the lower surface of the base plate and the upper surface of the pad have complimentary fiber-engaging strips engageable and disengageable one strip with another. Disengagement of the strips allows for the pad to be discarded when required and replaced with another pad. This negates the need to discard the full trowel with a significant saving in monetary cost and inconvenience.
Thus, it is an object of the present invention to provide a grout pad trowel that does not require the disposal of the handles and metal plate members once the pad is no longer satisfactory.
Accordingly, the invention provides in one aspect a trowel comprising (a) a handle means;
(b) a planar base plate having an upper face and a lower face, and affixed to said handle at said upper face;
(c) a soft pad member having a pad top surface and a pad bottom surface;
(d) retaining means affixing said pad top surface to said base plate lower face;
characterized in that said retaining means comprises engageable and dis-engageable adhering member means.
Preferably, the adhering means comprises fiber-engaging member means, which are repeatably engageable and disengageable one member to another member.
In one aspect, the invention provides a trowel as hereinabove defined wherein said adhering means comprises (i) a first retainer member having a first surface and a second surface, wherein (a) said first surface is adhered to and covers in whole or in part said lower face of said base plate, and (b) said second surface comprises a fiber-engageable face; and (ii) a second retainer member having (a) a first surface adhered to said pad top surface, and (b) a fiber-covered second surface, whereby said fiber-engageable surface of said first retainer member and said fiber-covered second surface of said second retainer member are each adherably engageable with and disengageable from the other.

Fig. I is a perspective view of a grouting pad trowel according to the prior art;
Figs. 2 and 3 are perspective views of a grouting pad trowel, in an engaged and disengaged assembly combination, respectively, according to the invention; and wherein the same numerals denote like parts.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
4 Fig. I shows generally as 10, a trowel having a metal planar base place 12 having an upper face 14 and a lower face 16 affixed to a handle 18 at upper face 14 by screws (not shown). Lower face 16 is permanently affixed by an adhesive layer (not shown) to the upper face 20 of a soft pad member 22.
Figs. 2 and 3 show generally as 30 and 40, respectively, a grout trowel assembly in an engaged and a disengaged combination, respectively.
Lower face 16 of base place 12 has a plurality of planar, rectangular fiber-engaging fiber strips 32 suitably located at peripheral portions of face 16. A
preferred strip 32 is formed of VELCRO fiber-engaging material, permanently affixed to face 16 by a suitable bonding adhesive.
Upper face 20 of pad 22 also has a similar plurality of planar, rectangular strips 42 of VELCRO material suitably located on and bonded to face 20 as to be operably engageable and disengageable with strips 32.
The shapes, thicknesses, sizes, numbers and locations of strips 32 and cooperable opposing strips 42 may be suitably varied, if desired. The shapes, sizes and numbers of fibers per unit area of strips 32, 42 are such as to effect sufficient engagement with opposing fibers of the opposing strip as to permit manual use of the assembly for its rubbing and cleaning duty on and between the tiles to be cleaned. However, the engagement between strips 32, 42 should not be too strong as to prevent disengagement of strips 32, 42 by vertically manually pressing base plate 12 from pad member 22. Aforesaid VELCRO fiber material of strips 32, 42 is most satisfactory in providing the desired and required engagement-disengagement physical properties.
In operation, when pad 22 has been sufficiently worn as to be replaced, disengagement from base plate 12 is effected and a new pad 22 engaged.
Although this disclosure has described and illustrated certain preferred embodiments of the invention, it is to be understood that the invention is not restricted to those particular embodiments. Rather, the invention includes all embodiments, which are functional or mechanical equivalence of the specific embodiments and features that have been described and illustrated.
