Description

BACKGROUND OF THE INVENTION

This invention relates to hand-held tools which a homeowner might use for washing his car having two or three foot long rods or poles for handles connected to one or another of a variety of mop heads. More particularly, it relates to a hand-held washing or waxing tool with a handle which may be fixed in a plurality of positions angularly disposed to a relatively flat plate to which a uniquely removable mitt is fastened.

Various mop heads with handles have been used in the past for floor mopping or waxing, wall cleaning or polishing, window washing, and vehicle cleaning and polishing. Each of these applications requires that the user manipulate the tool from a variety of positions using various features built into the pads at the ends of the handles and operating the tools as dictated by the various joints between the handles and the heads. Devices were proposed with hemispherically shaped sponge materials tied or clamped to the ends of the handles. Some sponges were mounted with screws or bolts to handle ends having plates on them so that the sponges could be rolled about on the surfaces to be cleaned. Some devices with pad-holding plates had handles fixed onto the plates at an angle by a shoe bolted to the plate. Others made use of knuckles or hinge joints affixed to the pad-holding plates, and the plates and pads wobbled constantly as they moved across a surface to be washed or polished. Still others had handles fastened to pad-holding plates by spring-loaded pins engaged in sockets which also allowed the plates and pads to wobble over the surface being washed.

Such washing, waxing or cleaning plates, pads and handles may be found in the following United States patents:

In U.S. Pat. No. 1,989,921, for example, a tool is illustrated containing a pole type handle for a waxing and polishing head and includes a rod attached to the head end of the handle. An eye formed at the outer end of the rod is curled around the stem of a bolt. That bolt joins two lugs fixed on a shaft in the waxing and polishing head. The eye of the rod allows the bolt to rotate in an up and down pivoting manner, and the head accordingly flops up and down and assumes a variety of planes as it is pushed over the surface which is being polished or washed.

In another U.S. Pat. No. 4,475,262, the inventor illustrates a curling broom which is intended to keep its wiping surface fully engaged at all times on an icy surface ahead of an advancing curling stone. The inventor posits a device which includes a swiveling joint allowing a handle to automatically adjust to the height of a user while leaving the sweeping surface of the broom parallel to the surface of the ice. Somewhat like the arrangement shown in the '921 patent just described, in the '262 patent a rod extends outwardly from the end of a pole-shaped handle. At the outer end of the rod a flattened strip portion of the rod is rolled into a tubular section, and that tube encloses the cylindrical body of a pin on the sweeping head of the broom to form a swivel joint. The inventor advises that this joint is preferably free enough to allow gravity, i.e., the distribution of weight in the head, to keep the sweeping surface always oriented to be parallel to the surface of the ice, regardless of the elevation of the handle.

Still another form of swivel joint connecting a handle to a washing head is shown in U.S. Pat. No. 5,596,787. In that patent, a pair of spaced apart pivot posts hold the ends of a pivot pin, and a lug which is joined at one end to the center portion of the pivot pin between the posts rotates with the pin about the pin's longitudinal axis. Adjacent the outer end of the lug, arms of a yoke grasp the ends of a second pin that extends through the lug. The longitudinal axis of the second pin is approximately normal to the longitudinal axis of the first pin. The bight portion of the yoke also carries a socket into which the end of a pole-shaped handle may be inserted. When the handle is moved about the second pin, i.e., from side to side, it always describes planes which include the longitudinal axis of the first pin. When the handle moves the lug attached to the first pin, i.e., up and down, it always describes a plane which intersects with the longitudinal axis of the first pin. The plane of the washing head is changed with respect to the handle whenever the handle is moved in any direction.

These tool constructions illustrate that artisans have been interested in establishing a constantly flexible angular relationship between a mop-type head, which is usually relatively flat, and the handle which manipulates the head. They have also emphasized maintaining the washing surface of the head fully in contact with the surface to be washed (or polished). Notably, the joint between the implement head and the handle remains very mobile.

In many applications, however, while it might be desirable occasionally to change the angular relationship between the head of the tool and the handle, due to varying contours in the surface to be washed, or the accessibility of the surface, it is also desirable to be able to maintain the head in a fixed position for washing and wiping one area and in a different fixed position for another area. Reaching upward from ground level to wash a window outside a building as compared to standing on the floor next to the window while inside the building is an example. In another context, flexibility of the head on the handle can be undesirable when a hard-to-reach area needs to be rubbed forcefully.

The present invention addresses both the desirability of quickly changing an angular relationship between a washing tool handle and the plane of the tool head and also the desirability of fixing that angular relationship at one angle or another, depending upon the type of job being addressed.

The present invention may also include a mitt which can be fastened over the face of the tool head in a secure manner to remain in place while at the same time accommodating any rigid position of the head on the handle as the tool is moved.

SUMMARY OF THE INVENTION

The present invention is embodied in a washing apparatus which includes a plate that has a substantially planar front face and a back face. There is a shank attached to the back face which extends outwardly from the plate in a direction away from the front face of the plate. A linking member joins a handle to the plate. The linking member has a tongue end with a tongue on it which extends between and connects the tongue end of the linking member and the shank. A hub, which may be on the tongue or on the shank, hinges the shank and the tongue together. In addition, there is a pin disposed in the shank and the tongue at a point spaced apart from the hub to fix the positions of the plate and the linking member in relation to each other on the hub.

From the foregoing, and from what follows, it will be apparent that the present invention solves the problems which users have had manipulating the kinds of washing or polishing tools that incorporate joints between the handle and the head which allow the head to move quite freely, and, on the other hand, manipulating the kinds of washing or polishing tools that do not provide for ready changes in the angular fixation of the head and handle to accommodate a variety of attitudes in a surface being washed or polished.

Accordingly, it is one of the objects of this invention to provide a washing or polishing apparatus with a handle which may be joined to a plate-like head of the tool at a variety of angles to the to the head.

It is another object of this invention to provide, in a washing or polishing apparatus, a connection between the handle and the head of the apparatus which includes a readily accessible locking pin and a variety of sockets to receive the pin so that the angle of the handle and the washing head in relation to each other may be easily and quickly changed.

It is a further object of this invention to provide a washing or polishing apparatus with a connection between the handle and the head of the apparatus which includes a mechanism that is simple and quick to operate for changing the angle of the handle to the head and still provides a secure connection which will stand up under repeated and sustained pressure during the time the apparatus is in use.

It is a further object of this invention to provide a washing or polishing apparatus in which the angle of the head may be varied with respect to the handle with a washing or polishing mitt which fits firmly about the head and remains securely in place notwithstanding changing the head through a variety of positions and forcefully applying it repeatedly to a surface to be washed or polished.

Other objects and features of this invention will be apparent to those skilled in the art of designing, constructing and using hand-held handle-operated washing or polishing tools from an examination of the following detailed description of a preferred embodiment of this invention and an examination of the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The preferred embodiment of this invention shown in the accompanying drawings will now be described, it being understood that the preferred form is illustrative and that the invention described herein is embodied in the claims appended to this description.

The washing apparatus 10 shown in FIG. 1 includes a handle 12 which may be a rod or a tube and may also include a grip element 14 located at a convenient point along the handle. When the apparatus is made in a size to be a tool for a do-it-yourselfer to wash a car, the handle 12 may be approximately eighteen to twenty-four inches long. The handle 12 may also be fixed in a variety of positions, in a manner which will shortly be explained, as shown in the phantom positions 12a and 12b.

The washing apparatus 10 also includes a washing head assembly 16 which comprises a plate 18 having a back face 20 and a substantially planar front face 22 (see FIG. 5). A shank 24 is attached to the back face of the plate, or it may be formed there if the plate 18 is manufactured in one piece by a molding or similar process. The shank extends outwardly from the back side of plate 18 in a direction leading away from front face 22. That direction is approximately normal to the plane of front face 22.

At the outer end of shank 24 there is a yoke 26 which includes first and second arms 28 and 30, respectively. Those arms, which are spaced apart from one another, form a slot 32 between them. A linking member 34 joins handle 12 to the back face 20 of plate 18 in the following manner. Handle 12 may be provided with threads 36 at one end and connected to the linking member 34 in the threaded socket end 38 of the linking member. Opposite the socket end 38, the linking member is provided with a tongue end 40 for engaging the shank 24. Tongue 42, which may be integral with linking member 34, is arranged to extend from tongue end 40 of the linking member into slot 32 between the first and second arms 28 and 30 of yoke 26. A hub 44 is held in lower apertures 46 formed in arms 28 and 30, and a central aperture 48 in the tongue 42 having approximately the same diameter as hub 44 is engaged on the hub between the arms 28 and 30, thus hinging the shank 34 and the tongue 42 together on the hub.

There are also several outlying apertures 50 in tongue 42 arranged around the central aperture 48 in the tongue. In the arms 28 and 30, at locations spaced apart from the hub 44, a complementary pair of pin-holding apertures 52 are arranged to receive a locking pin 54. The outlying apertures 50 are formed in tongue 42 in a path which brings the outlying apertures into registry with the pin-holding apertures 52 as the tongue 42 is rotated around hub 44. When one of the outlying apertures 50, such as 50a, is registered with the pin-holding apertures 52, pin 54 may be inserted into the aligned apertures 52 and 50a to fix the positions of plate 18 and the linking member 34 on hub 44 at a fixed angle to each other, such as the angle alpha (see FIG. 3). Similarly, when another outlying aperture, such as 50b, is registered with the pin-holding apertures 52, pin 54 may be inserted in the aligned apertures 52 and 50b to fix the positions of plate 18 and the linking member 34 on the hub 44 at another fixed angle to each other, such as the angle beta (see FIG. 3). As shown, the outlying apertures 50 in the tongue 42 are arcuately arranged in the tongue in a path which coincides with the apertures 52 in arms 28 and 30 so that the pin 54, when engaged in one or another of the apertures 50, will engage the tongue at a variety of locations in the tongue.

The washing apparatus 10 may also include a fluid absorbing mitt 56 which is releaseably attached to plate 18 overlying the front face 22 of the plate. Mitt 56 includes a base web element 58 and a washing fabric element 60. The fabric element 60 has an outwardly facing surface 62, which is preferably a roughly textured polyurethane surface for contacting a surface to be washed, and it is fastened at its perimeter 72 by stitching 64 to the base web 58. A fluid absorbing member such as sponge 66 is enclosed between the fabric element 60 and the base web 58 for lengthening the fluid retention of the mitt while it is in use or dispensing a fluid or compound during use if the sponge has been treated beforehand to contain such a fluid or compound.

At least a pair of straps 68 are attached to washing fabric 60 at their first ends 70. Those ends are located along the perimeter 72 of the washing fabric 60. Second ends 74 of straps 68 are extendable across and over the back face 20 of plate 18 for engagement upon portions of the washing fabric adjacent a substantially opposite edge of the plate spaced from each strap's first end (See FIG. 1). The second ends 74 may include hook and loop sections for easy engagement and fastening. When so fastened, the straps 68 pull the perimeter 72 of the washing fabric element 60 over the edge of plate 18 (See FIG. 4), and the edge of the base web 58 as well, to fasten the mitt 56 securely against the front face 22 of plate 18. When the mitt is secured this way, the tool 10 may be rubbed affirmatively over a surface to be washed, and the mitt will not be loosened or dislodged.

With respect to the diameters of the base web 58 and the washing fabric 60 in relation to each other, as well as in relation to the diameter of plate 18, it has been found particularly useful to make the diameter D (See FIG. 5) of plate 18 approximately six inches, the diameter D′ of the base web 58 about nine inches, and the diameter D′″ of the washing fabric element 60 about ten inches. A sponge, such as the sponge 66, may be incorporated in this construction, too. Such a sponge may be about three quarters of an inch thick and have about a five and seven-eighths inches diameter D″. The sponge 66 is enclosed in the envelope formed by the washing fabric and the base web as their perimeters are closed together, and the resulting mitt is strapped over the plate 18 in the manner described above with the base web 58 fastened securely against the front face 22 of the plate.

It is evident from the preceding disclosure that even though particular forms of the invention have been illustrated and described, still, various modifications can be made without departing from the true spirit and scope of the invention. No limitations on the invention are intended, and its true scope is set forth in the following claims.
