Abstract
A scraper device for attachment to a broom of the type having a head and a handle, the handle having a lower end for mounting to the head and an upper end. The scraper device is comprised of a handle mounting member for connecting the scraper device to the handle, the handle mounting member defining an aperture which is sized to permit the handle to be accepted therein. A blade carrying member depends from the handle mounting member so that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the blade carrying member extends downwards and forwards over the head. The scraper device is further comprised of an anchoring system so that upward movement of the scraper device relative to the handle is restricted when it is attached to the broom.
Finally, a scraper blade is located along the edge of the blade carrying member opposite the handle mounting member, so that debris may be scraped from a surface by the scraping device when the orientation of the broom is reversed from that normally used for sweeping. The scraper device may also comprise one or more bracing members for bracing the handle when the scraper device is attached to the broom.
Finally, a scraper blade is located along the edge of the blade carrying member opposite the handle mounting member, so that debris may be scraped from a surface by the scraping device when the orientation of the broom is reversed from that normally used for sweeping.

Description
-SCRAPER AND BRACE ATTACHMENT FOR A BROOM
TECHNICAL FIELD
The present invention relates to a scraper device for attachment to a broom having a head and a handle, the handle having a lower end for mounting to the head. The scraper device may include means for bracing the handle when the 10 scraper device is attached to the broom.
BACKGROUND ART
Conventional push brooms are used for sweeping shop floors, public buildings, garden patios, roads, sidewalks, etc. Often the push broom encounters materials such as mud, snow, ice, chewing gum, and other debris which stick to the surface being swept. In such circumstances, the sweeping action of the push broom alone is insufficient to free the sticking materials. As a result, the user of the push broom may reverse the broom head by turning it upside down and using the broom 20 head to scrape the materials off the surface being cleaned. However, the head alone may not be sufficient to scrape the surface and it is subjected to unnecessary wear and tear. Alternatively, a separate cleaning tool such as a scraper may be used.
However, the use of a separate cleaning tool may be inconvenient.
-As a result, scraper attachments for push brooms have been developed.
United States Patent No. 5,123,138 issued June 23, 1992 to Flamm describes a combined push broom and scraping apparatus comprised of a number of parts welded together to form a relatively complex structural arrangement. Further, the apparatus is mounted to the push broom by a series of wood screws screwed directly into the head of the broom. This manner of mounting renders attachment and detachment of the apparatus a relatively time-consuming and difficult task, likely requiring the use of tools to do so. Further, the manner of mounting the apparatus damages the broom head and may weaken it structurally.
Similarly, United Kingdom Patent Application No. 2,150,015A filed November 16, 1983 by Dymott et. al. and published June 26, 1985 describes a combined brushing and scraping tool. The scraping tool is attached to the broom by fasteners which mount directly into both the broom handle and the broom head.
Thus, again, attachment and detachment of the tool to the broom are relatively time-consuming and difficult, likely requiring the use of tools, and both the handle and the head are damaged and may be weakened structurally.
Other prior combination tools such as those described in United States Patent No. 2,163,979 issued June 27, 1939 to Judson and United States Patent No. 2,742,658 issued April 24, 1956 to Sproston have been developed which are mounted to the push broom without damaging it or weakening it structurally. The 212729~
Sproston patent describes a scraper for attachment to a broom which is comprised of a relatively complex structural arrangement made up of a number of pieces. In the preferred embodiment, the scraper is directly mounted to the broom head by a bolt that passes through the broom head. However, an alternate embodiment is also described for use with a broom head having two sockets in it which merge and form an opening in the bottom of the broom head, thus forming a V-shaped passage.
Conventionally, the broom handle is capable of being mounted in either of these sockets. When using the alternate embodiment, the broom handle cannot be mounted to the head conventionally as both sockets are used to mount the scraper to 10 the broom head. This manner of mounting utilizes a U-bolt placed within the sockets and held in place by wing nuts. This manner of mounting also renders attachment and detachment of the scraper relatively time-consuming and difficult to perform.
Although the structure of the actual scraper attachment in the Judson patent is less complex than in the Sproston patent, the manner of mounting the scraper attachment to the push broom in the Judson patent renders attachment and detachment of the scraper attachment relatively time-consuming and difficult to perform. The scraper attachment is only for use with a push broom of the type having two sockets in the head which merge and form an opening in the bottom of 20 the broom head. The scraper attachment is mounted to the handle by a split collar clamp which is held in place by a bolt and a nut. The scraper attachment is mounted to the broom head by one of the sockets in the broom head. A bolt extends from the scraper into one of the sockets and is threaded into a bracket, also located within the socket. The bracket includes a curved arm which extends out the other end of the socket and contacts the outer surface of the head of the broom. Tools may be required to mount the scraper attachment and to tighten it in place on the push broom.
Finally, when using a push broom, the broom handle is subjected to stress which may cause the broom handle to break. This is most likely to occur at the point where the handle is mounted to the broom head. Further, this problem may 10 be compounded when a force is applied through the handle for using the scraper attachment. However, with the exception of the Dymott patent, none of the prior art described herein addresses this difficulty. With respect to the Dymott patent, although the scraping tool includes a brace member, the brace member is mounted into the broom handle, as well as the head, which structurally weakens the portion of the broom which the brace is designed to support.
There is therefore a need in the industry for a scraper device for attachment to a broom which has a relatively simple structure and which may be attached and detached to the broom in a relatively quick and easy manner as 20 compared to known scraper devices, without damaging the broom such that its structure is weakened. Further, there is a need in the industry for means for bracing the handle of the broom when the scraper device is attached to the broom, without damaging the handle such that the structure of it is weakened.
DISCLOSURE OF INVENTION
The present invention relates to a scraper device for attachment to a broom of the type having a head and a handle, the handle having a lower end for mounting to the head. The scraper device is attachable to and detachable from the broom in a relatively quick and simple manner without causing any damage to the 10 broom that may weaken the broom structurally. Further, the present invention relates to means for bracing the handle when the scraper device is attached to the broom.
In one aspect of the invention, the invention comprises a scraper device for attachment to a broom of the type having a head and a handle, the handle having a lower end for mounting to the head and an upper end. The scraper device comprises: a handle mounting member for connecting the scraper device to the handle, the handle mounting member defining an aperture which is sized to permit the handle to be accepted therein; a blade carrying member depending from the handle mounting member so that when the handle is mounted to the head and the 20 upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the blade carrying member extends downwards and forwards over the head; means for anchoring the scraper device when it is attached to the broom so that upward movement of the scraper device relative to the handle is restricted; and a scraper blade located along the edge of the blade carrying member opposite the handle mounting member, so that debris may be scraped from the surface by the scraper device when the orientation of the broom is reversed from that normally used for sweeping.
In this aspect of the invention, the scraper device may further comprise means, associated with the blade carrying member, for bracing the handle when the scraper device is attached to the broom. These bracing means preferably comprise 10 at least one bracing member depending from the lower surface of the blade carrying member which contacts the head of the broom in order to support the handle from the stresses which tend to break the handle at the point where it is mounted to the broom head. Suitable bracing means may be comprised of a pair of bracing members depending from the lower surface of the blade carrying member which abut against the head when the scraper device is attached to the broom. However, other arrangements including one or more bracing members are possible, so long as the handle is supported thereby.
Further, the blade carrying member may comprise at least one rib 20 positioned adjacent the scraper blade for increasing the rigidity of the scraper blade.
Further, the blade carrying member preferably depends from the handle mounting member at a depending angle measured between the upper surfaces of the handle mounting member and the blade carrying member. The handle mounting member may be resiliently rotated relative to the blade carrying member so as to alter the depending angle. The depending angle at rest may be less than the depending angle when the scraper device is attached to the broom and the blade carrying member is contacting the head, so that when the scraper device is attached to the broom, the handle mounting member is urged to rotate relative to the blade carrying member to reduce the depending angle, thus causing a gripping effect of the 10 handle mounting member against the handle. The aperture in the handle mounting member may be sized so that the handle fits snugly within the aperture in order to assist in the gripping effect. Further, the aperture may be defined by a sharp edge, in order to assist further in the gripping effect.
The handle mounting member and the blade carrying member may be formed from one piece of material. The scraper blade may be formed by the edge of the blade carrying member opposite the handle mounting member.
The anchoring means of the scraper device comprise a fastening 20 system associated with the blade carrying member which serves to secure the blade carrying member either to the head or the handle, and preferably includes one or more bolts, plugs, cables or other fasteners which couple the blade carrying member -to the head or handle without requiring modification of the broom by drilling or screwing.
Suitable anchoring means may be comprised of: the head including a first socket for mounting the handle to the head and a second socket, the sockets convergingly extending from the upper surface of the head to the lower surface of the head so that they intersect near the lower surface of the head; the blade carrying member defining a hole therein so that when the handle is mounted to the head using the first socket and the upper end of the handle is passed through the aperture and 10 the handle mounting member is positioned adjacent the lower end of the handle, the hole corresponds with the second socket; and a plug having a first end which is sized to fit within the second socket and having a second end which is larger than the hole, in order that the first end of the plug may be passed through the hole and secured within the second socket, and so that the second end of the plug will not pass through the hole and will secure the blade carrying member to the head. The second socket may be threaded and the plug may be sized and threaded so that it may be secured into the second socket and thereby secured to the head. The plug may be long enough to abut against the handle at the point of convergence of the sockets when the lower end of the handle is in the first socket and the plug is in the second 20 socket, so as to restrict the movement of the handle in the first socket. The first end of the plug may include means for restraining the handle when the lower end of the handle is in the first socket and the plug is in the second socket. The restraining means may comprise a point at the first end of the plug. Further, the restraining means may comprise a rubber pad at the first end of the plug.
Other suitable anchoring means are comprised of: a U-shaped bolt with two ends for accepting tighteners; a pair of tighteners for attaching to the ends of the U-shaped bolt; and the blade carrying member defining two openings which are sized and spaced apart from one another in order to accept the ends of the U-shaped bolt, and which are positioned next to each other along an axis which is substantially perpendicular to the axis defined by the aperture in the handle mounting member; so 10 that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the U-shaped bolt can be positioned around the handle and the ends of the U-shaped bolt can be passed through the openings in the blade carrying member and the tighteners can be attached to the ends of the U-shaped bolt and tightened in order to secure the U-shaped bolt to the handle and restrict the upward movement of the scraper device relative to the handle. The surface of the U-shaped bolt may be textured so that it may be more positively secured to the handle.
Further, the surface of the U-shaped bolt may be textured by threads that extend over substantially the entire length of the U-shaped bolt and the tighteners may be 20 threaded for attaching to the ends of the U-shaped bolt.
Still other suitable anchoring means are comprised of: a flexible cable having two ends for accepting tighteners; a pair of tighteners for attaching to the ends of the cable; and the blade carrying member defining two openings spaced apart from one another for accepting the cable therethrough and which are positioned next to each other along an axis which is substantially perpendicular to the longitudinal axis of the head when the scraper device is attached to the broom; so that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the cable can be successively passed through the openings and about the 10 head and the tighteners can be attached to the ends of the cable and tightened in order to secure the cable about the head and restrict the upward movement of the scraper device relative to the handle. The blade carrying member may define two pairs of openings spaced apart from one another and positioned such that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, one pair of openings is located adjacent to the head on either side of the handle. The ends of the cable may be threaded for accepting the tighteners and the tighteners may be threaded for attaching to the ends of the cable.
The scraper device may be further comprised of a cleaning flange depending from the lower surface of the blade carrying member substantially parallel with the scraper blade such that when the scraper device is attached to the broom, -the cleaning flange is directed towards the head for limiting debris from being trapped between the head and the scraper device. The cleaning flange may be welded to the lower surface of the blade carrying member.

BEST MODE OF CARRYING OUT INVENTION
Referring to Figures 1 through 3, the invention is comprised of a scraper device (20) for attachment to a broom (22). The broom (22) is of a type 20 conventionally known as a push broom or brush broom and having an elongated head (24) and a handle (26). The head (24) is comprised of an upper surface (28) and a lower surface (30) having attached bristles (32) for sweeping. The handle (26) -is conventionally a pole having an upper end (34) for gripping by the user of the broom (22) and a lower end (36) for mounting to the upper surface (28) of the head (24). The handle (26) typically extends from the upper surface (28) of the head (24) at an angle from vertical orientation in order to allow the user of the broom (22) to grip the upper end (34) of the handle (26) while maintaining the contact of the bristles (32) with the surface to be cleaned.
The scraper device (20) is comprised of a handle mounting member (38), a blade carrying member (40), a scraper blade (42) and means for anchoring 10 the scraper device. The handle mounting member (38) has an upper surface (44) and a lower surface (46) and defines an aperture (48). The aperture (48) is sized to permit the handle (26) to be accepted therein.
Preferably, the blade carrying member (40) has an upper edge (50), a lower edge (52) and a first and second side edge (54, 56). Further, the blade carrying member (40) has an upper surface (58) and a lower surface (60). In the preferred embodiment, the upper edge (50) of the blade carrying member (40) is connected to the handle mounting member (38) such that the blade carrying member (40) depends from the handle mounting member (38).
When the handle (26) is mounted to the head (24), the upper end (34) of the handle (26) may be passed through the aperture (48) in the handle mounting member (38) from the lower surface (46) of the handle mounting member (38) to the upper surface (44) of the handle mounting member (38) and the handle mounting member (38) may be positioned adjacent the lower end (36) of the handle (26).
When the handle mounting member (38) is so positioned, the blade carrying member (40) depends from the handle mounting member (38) in a manner so that the blade carrying member (40) extends downward, towards the bristles (32), and forwards over the head (24) of the broom (22). The blade carrying member (40) is positioned so that when the handle (26) of the broom (22) is gripped by the user in a manner for sweeping, with the bristles (32) in contact with the surface to be cleaned, the blade 10 carrying member (40) extends forwards, away from the user on the side of the handle (26) and the head (24) opposite, or not facing, the user.
The blade carrying member (40) depends from the handle mounting member (38) at a depending angle. The depending angle is measured between the upper surface (44) of the handle mounting member (38) and the upper surface (58) of the blade carrying member (40). The point of connection between the handle mounting member (38) and the blade carrying member (40) allows the handle mounting member (38) to be resiliently rotated relative to the blade carrying member (40) so that the depending angle may be altered. In the preferred embodiment, the 20 handle mounting member (38) and the blade carrying member (40) are integral.
They are formed from one piece of a resilient material which allows for the resilient rotation of the handle mounting member (38) relative to the blade carrying member -(40). In the preferred embodiment, the handle mounting member (38) and the blade carrying member (40) are constructed out of a single piece of sheet metal which is bent to form the depending angle. Alternatively, the handle mounting member (38) and the blade carrying member (40) may be molded from a resilient plastic into a single piece defining the depending angle.
When the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26) and the means for anchoring the scraper device (20) are not employed, the blade carrying member (40) is at rest. When at rest, the 10 depending angle is such that the blade carrying member (40) is held a spaced distance from the head (24). When the means for anchoring the scraper device (20) are employed, the handle mounting member (38) is resiliently rotated relative to the blade carrying member (40), increasing the depending angle, and the lower surface (60) of the blade carrying member (40) is brought into contact with the head (24).
Thus the depending angle at rest is less than the depending angle when the blade carrying member (40) is contacting the head (24). The depending angle at rest may vary depending upon, amongst other factors, the type and size of the head (24) of the broom (22), the type of material from which the handle mounting member (38) and the blade carrying member (40) are constructed, and the manner of connection 20 between the handle mounting member (38) and the blade carrying member (40).
However, in the preferred embodiment, the depending angle at rest is approximately 40 degrees.
As a result of the varying depending angle and the resilient connection between the handle mounting member (38) and the blade carrying member (40), when the scraper device (20) is attached to the broom (22) by the anchoring means, the handle mounting member (38) is urged to rotate relative to the blade carrying member (40) to reduce the depending angle. This causes a gripping effect of the handle mounting member (38) against the handle (26). The gripping effect assists in minimizing unwanted movement or rotation of the handle (26) relative to the head (24). For example, the head (24) may include a threaded socket for accepting a threaded lower end (36) of the handle (26). During use, the handle (26) may tend to 10 loosen up and unscrew from the socket in the head (24). The gripping effect aids in minimizing the rotation of the handle (26) relative to the head (24), thus assisting in maintaining a tight fit or connection between the head (24) and the handle (26).
Preferably, to assist in the gripping effect, the aperture (48) is sized such that the handle (26) fits snugly within the aperture (48) yet still allowing for the handle (26) to pass through the aperture (48) substantially unimpeded. To further assist in the gripping effect, the aperture (48) is defined by a sharp edge.
A scraper blade (42) is located along the lower edge (52) of the blade 20 carrying member (40) opposite to the handle mounting member (38). In the preferred embodiment, the scraper blade (42) is integral with the blade carrying member (40) and is formed by the lower edge (52) of the blade carrying member (40). Thus, the scraper blade (42) is also constructed of sheet metal in the preferred embodiment.
Where the blade carrying member (40) is made of another material such as plastic, it is preferred to mount a scraper blade (42) constructed of metal along the lower edge (52) of the blade carrying member (40) to improve the wear of the scraper device (20). Further, the blade carrying member includes a rib (62) for increasing the rigidity of the scraper blade (42). The rib (62) is located at the lower edge (52) of the blade carrying member (40) such that it is positioned adjacent the scraper blade (42) and has a longitudinal axis which is substantially parallel with the longitudinal axis of the scraper blade (42). A greater number of ribs (62) may be used as required to 10 increase the rigidity of the scraper blade (42).
When the scraper device (20) is attached to the broom (22) and the anchoring means are employed, the scraper blade (42) is out of contact with the suRace to be cleaned during normal use of the broom (22). The scraper blade (42) does not inteRere with the normal use of the broom (22). The scraper device (20) is utilized by reversing the orientation of the broom (22) from that normally used for sweeping. The upper suRace (58) of the blade carrying member (40) faces and is adjacent to the suRace to be cleaned by the scraper device (20) and the bristles (32) are out of contact with the suRace to be cleaned.
During use of the scraper device (20), debris scraped from the suRace being cleaned may become trapped between the bristles (32) or the head (24) and the scraper device (20). Further, debris may become similarly trapped when usingthe broom (22) for sweeping. As a result, in the preferred embodiment, the scraper device (20) includes a cleaning flange (64). The cleaning flange (64) depends from the lower surface (60) of the blade carrying member (40) at its lower edge (52).Further, the longitudinal axis of the cleaning flange (64) is substantially parallel with the scraper blade (42). As a result, when the scraper device (20) is attached to the broom (22), the cleaning flange (64) is directed towards the head (24). Thus, the cleaning flange (64) blocks the space between the scraper device (20) and the head (24) and limits any debris being trapped therebetween. In the preferred embodiment, the cleaning flange (64) is constructed of metal similar to the blade carrying member (40) and is welded to the lower surface (60) of the blade carrying member (40).
Further, the scraper device (20) includes means for bracing the handle (26) when the scraper device (20) is attached to the broom (22). In the preferred embodiment, the bracing means are a pair of bracing members (66, 68) which depend from the lower surface (60) of the blade carrying member (40). The bracing members (66, 68) are flanges or protrusions from the blade carrying member (40). A
first bracing member (66) is located adjacent the first side edge (54) of the blade carrying member (40). A second bracing member (68) is located adjacent the second side edge (56) of the blade carrying member (40). Both bracing members (66, 68) extend from the upper edge (50) of the blade carrying member (40), where the blade carrying member (40) is connected to the handle mounting member (38), and along 2l27294 the side edges (54, 56) of the blade carrying member (40). When the scraper device (20) is attached to the broom (22), and the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the bracing members (66, 68) abut against the upper surface (28) of the head (24) so that the bracing members (66, 68) brace the handle (26). Further, the abutment of the bracing members (66, 68) against the head (24) restricts the downward movement, or movement away from the upper end (34) of the handle (26), of the scraper device (20) relative to the handle (26).
In the preferred embodiment, the bracing members (66, 68) are integral with the blade carrying member (40). The blade carrying member (40), including the bracing members (66, 68) are cut from sheet metal. The bracing members (66, 68) are then bent or folded towards the lower surface (60) of the blade carrying member (40) to depend therefrom. Although the bracing means are preferably comprised of two bracing members (66, 68) as described above, other arrangements including one or more bracing members are possible as long as the bracing member depends from the lower surface (60) of the blade carrying member (40) and contacts the head (24) in order to support the handle (26) from the stresses which tend to break the handle (26) at the point where it is mounted to the head (24).
The preferred embodiment further includes a hanging hole (72). The hanging hole (72) is defined by the blade carrying member (40) and is located adjacent the lower edge (52) of the blade carrying member (40). Further, the hanging hole (72) is located approximately midway between the first side edge (54) and the second side edge (56) of the blade carrying member (40). When the scraper device (20) is attached to the broom (22) and the anchoring means are employed, the hanging hole (72) is used for storing the broom (22) by placing the hanging hole (72) over a hook, nail or similar protrusion located on a wall. In this manner, the broom (22) with the attached scraper device (20) may be safely and conveniently stored.
As stated above, the scraper device (20) includes means for anchoring 10 the scraper device (20) when it is attached to the broom (22). The anchoring means act to restrict the upward movement of the scraper device (20) relative to the handle (26), or in other words, the movement of the scraper device (20) towards the upper end (34) of the handle (26). Further, the anchoring means assist in the gripping effect described above. The anchoring means are comprised of a fastening system associated with the blade carrying member (40) for securing the blade carrying member (40) to either the head (24) or the handle (26) of the broom (22). Further, the anchoring means include one or more bolts, plugs, cables or other fasteners which couple the blade carrying member (40) to the broom (22) without requiring modification of the broom (22) by drilling or screwing.
In the preferred embodiment, as shown in Figures 1 through 3, the anchoring means are comprised of a fastener, being a U-shaped bolt (74), a pair of tighteners (76, 78) and the blade carrying member (40) defining a first opening (80) and a second opening (82). The first and second openings (80, 82) in the blade carrying member (40) are sized and spaced apart from one another in order to accept the ends of the U-shaped bolt (74) therein. Further, the first and second openings (80, 82) are positioned next to each other along an axis which is substantially perpendicular to the axis defined by the aperture (48) in the handle mounting member (38). Finally, when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the first and second openings (80, 82) are located between the handle mounting member (38) and the head (24) of the broom (22).
As a result of the placement of the first and second openings (80, 82), when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the U-shaped bolt (74) can be positioned around the handle (26) and the ends of the U-shaped bolt (74) can be passed from the lower surface (60) of the blade carrying member (40), through the first and second openings (80, 82) to the upper surface (58) of the blade carrying member (40). The ends of the U-shaped bolt (74) are threaded for accepting the tighteners (76, 78). The tighteners (76, 78) are compatibly threaded for attaching to the ends of the U-shaped bolt (74). Thus, when the U-shaped bolt (74) is in position around the handle (26), the tighteners (76, 20 78) can be attached to the ends of the U-shaped bolt (74) and tightened against the upper surface (58) of the blade carrying member (40) in order to secure the U-shaped bolt (74) to the handle (26) and restrict the upward movement of the scraper device (20) relative to the handle (26). To more positively secure the U-shaped bolt (74) to the handle (26), the surface of the U-shaped bolt (74) is textured by threads that extend over substantially the entire length of the U-shaped bolt (74).
In a second embodiment of the scraper device (20), as shown in Figures 4 through 6, the anchoring means are comprised of a fastener, being a flexible cable (84), a pair of tighteners (86, 88) and the blade carrying member (40) defining a first and second pair of openings (90, 92). More or fewer openings may be used as required to anchor the scraper device (20). With respect to each pair of 10 openings in the preferred form of the second embodiment, the two openings are spaced apart from one another and are positioned next to each other along an axis which is substantially perpendicular to the longitudinal axis of the head (24) when the scraper device (20) is attached to the broom (22). Further, the first and second pairs of openings (90, 92) are spaced apart from one another and positioned such that when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), one pair of openings is located adjacent to the head (24) on either side of the handle (26). Thus, the first pair of openings (90) is located between the handle (26) and the first side edge (54) of the blade carrying member (40) and the second pair of openings (92) is located between the handle (26) and the second side 20 edge (56).
As a result of the placement of the pairs of openings (90, 92), when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the ends of the cable (84) can be successively passed through the openings(90, 92) and about the head (24). For example, the cable (84) may pass from the upper surface (58) of the blade carrying member (40), through the opening in the first pair of openings (90) nearest to the upper edge (50) of the blade carrying member (40), around the head (24), through the opening in the first pair of openings (90) nearest to the lower edge (52) of the blade carrying member (40). The cable (84)then passes across the upper surface (58) of the blade carrying member (40), through the opening in the second pair of openings (92) nearest to the lower edge (52) of the blade carrying member (40), around the head (24), and through the opening in the second pair of openings (92) nearest to the upper edge (50) of the blade carrying member (40) to the upper surface (58) of the blade carrying member (40). The specific passing of the cable (84) may vary as long as the cable (84) loops around the head (24) and the ends of the cable (84) are located on the upper surface (58) of the blade carrying member (40) for ease of access to them.
The ends of the cable (84) are threaded for accepting the tighteners (86, 88). The tighteners (86, 88) are compatibly threaded for attaching to the ends of the cable (84). Thus, when the cable (84) is in position around the head (24), the tighteners (86, 88) can be attached to the ends of the cable (84) and tightened against the upper surface (58) of the blade carrying member (40) in order to secure 212729~
the cable (84) about the head (24) and restrict the upward movement of the scraper device (20) relative to the handle (26).
In a third embodiment of the scraper device (20), as shown in Figures 7 through 9, the anchoring means are comprised of the head (24) including a first socket (94) and a second socket (96), a hole (98) in the blade carrying member (40) and a fastener, being a plug (100). As shown in Figure 8, the sockets (94, 96) convergingly extend from the upper surface (28) of the head (24) to the lower surface (30) of the head (24) so that they intersect near the lower surface (30). In a conventional broom, the two sockets (94, 96) are substantially identical and at approximately right angles to each other. Thus, a V-shaped passage is formed in the broom (22). Both sockets (94, 96) are threaded such that a threaded lower end (36) of the handle (26) may be mounted in either socket (94, 96) as desired. In the preferred form of the third embodiment, the lower end (36) of the handle (26) ismounted in the first socket (94).
As stated, the blade carrying member (40) defines a hole (98). When the handle (26) is mounted to the head (24) using the first socket (94), and the upper end (34) of the handle (26) is passed through the aperture (48) and the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the hole (98) corresponds with the second socket (96). The second socket (96) is 212729~
-threaded for receiving the plug (100) and the plug (100) is sized and threaded so that it may be secured into the second socket (96) and thereby secured to the head (24).
The plug (100) has a first end (102) which is sized to fit within the second socket (96) and a second end (104) which is larger than the hole (98). Thus, in use, the first end (102) of the plug (100) is passed through the hole (98) and secured within the second socket (96) by tightening the plug (100). The second end (104) of the plug (100) will not pass through the hole (98) and therefore secures the blade carrying member (40) to the head (24).
Further, the plug (100) is long enough for the first end (102) to abut against the handle (26) at the point of convergence of the first and second sockets (94, 96) when the lower end (36) of the handle (26) is in the first socket (94) and the plug (100) is in the second socket (96). The abutment of the plug (100) against the handle (26) restricts the movement of the handle (26) in the first socket (94) thus inhibiting the loosening of the handle (26) during use of the broom (22) or scraper device (20). To further restrict movement, the first end (102) of the plug (100)includes means for restraining the handle (26). The restraining means are comprised of a point (106) at the first end (102) of the plug (100). The point (106) engages the handle (26) when the lower end (36) of the handle (26) is in the first socket (94) and the plug (100) is in the second socket (96), and thereby restricts its movement.
Other restraining means may also be used such as a rubber pad (not shown) at thefirst end (102) of the plug (100).
TECHNICAL FIELD
The present invention relates to a scraper device for attachment to a broom having a head and a handle, the handle having a lower end for mounting to the head. The scraper device may include means for bracing the handle when the 10 scraper device is attached to the broom.
BACKGROUND ART
Conventional push brooms are used for sweeping shop floors, public buildings, garden patios, roads, sidewalks, etc. Often the push broom encounters materials such as mud, snow, ice, chewing gum, and other debris which stick to the surface being swept. In such circumstances, the sweeping action of the push broom alone is insufficient to free the sticking materials. As a result, the user of the push broom may reverse the broom head by turning it upside down and using the broom 20 head to scrape the materials off the surface being cleaned. However, the head alone may not be sufficient to scrape the surface and it is subjected to unnecessary wear and tear. Alternatively, a separate cleaning tool such as a scraper may be used.
However, the use of a separate cleaning tool may be inconvenient.
-As a result, scraper attachments for push brooms have been developed.
United States Patent No. 5,123,138 issued June 23, 1992 to Flamm describes a combined push broom and scraping apparatus comprised of a number of parts welded together to form a relatively complex structural arrangement. Further, the apparatus is mounted to the push broom by a series of wood screws screwed directly into the head of the broom. This manner of mounting renders attachment and detachment of the apparatus a relatively time-consuming and difficult task, likely requiring the use of tools to do so. Further, the manner of mounting the apparatus damages the broom head and may weaken it structurally.
Similarly, United Kingdom Patent Application No. 2,150,015A filed November 16, 1983 by Dymott et. al. and published June 26, 1985 describes a combined brushing and scraping tool. The scraping tool is attached to the broom by fasteners which mount directly into both the broom handle and the broom head.
Thus, again, attachment and detachment of the tool to the broom are relatively time-consuming and difficult, likely requiring the use of tools, and both the handle and the head are damaged and may be weakened structurally.
Other prior combination tools such as those described in United States Patent No. 2,163,979 issued June 27, 1939 to Judson and United States Patent No. 2,742,658 issued April 24, 1956 to Sproston have been developed which are mounted to the push broom without damaging it or weakening it structurally. The 212729~
Sproston patent describes a scraper for attachment to a broom which is comprised of a relatively complex structural arrangement made up of a number of pieces. In the preferred embodiment, the scraper is directly mounted to the broom head by a bolt that passes through the broom head. However, an alternate embodiment is also described for use with a broom head having two sockets in it which merge and form an opening in the bottom of the broom head, thus forming a V-shaped passage.
Conventionally, the broom handle is capable of being mounted in either of these sockets. When using the alternate embodiment, the broom handle cannot be mounted to the head conventionally as both sockets are used to mount the scraper to 10 the broom head. This manner of mounting utilizes a U-bolt placed within the sockets and held in place by wing nuts. This manner of mounting also renders attachment and detachment of the scraper relatively time-consuming and difficult to perform.
Although the structure of the actual scraper attachment in the Judson patent is less complex than in the Sproston patent, the manner of mounting the scraper attachment to the push broom in the Judson patent renders attachment and detachment of the scraper attachment relatively time-consuming and difficult to perform. The scraper attachment is only for use with a push broom of the type having two sockets in the head which merge and form an opening in the bottom of 20 the broom head. The scraper attachment is mounted to the handle by a split collar clamp which is held in place by a bolt and a nut. The scraper attachment is mounted to the broom head by one of the sockets in the broom head. A bolt extends from the scraper into one of the sockets and is threaded into a bracket, also located within the socket. The bracket includes a curved arm which extends out the other end of the socket and contacts the outer surface of the head of the broom. Tools may be required to mount the scraper attachment and to tighten it in place on the push broom.
Finally, when using a push broom, the broom handle is subjected to stress which may cause the broom handle to break. This is most likely to occur at the point where the handle is mounted to the broom head. Further, this problem may 10 be compounded when a force is applied through the handle for using the scraper attachment. However, with the exception of the Dymott patent, none of the prior art described herein addresses this difficulty. With respect to the Dymott patent, although the scraping tool includes a brace member, the brace member is mounted into the broom handle, as well as the head, which structurally weakens the portion of the broom which the brace is designed to support.
There is therefore a need in the industry for a scraper device for attachment to a broom which has a relatively simple structure and which may be attached and detached to the broom in a relatively quick and easy manner as 20 compared to known scraper devices, without damaging the broom such that its structure is weakened. Further, there is a need in the industry for means for bracing the handle of the broom when the scraper device is attached to the broom, without damaging the handle such that the structure of it is weakened.
DISCLOSURE OF INVENTION
The present invention relates to a scraper device for attachment to a broom of the type having a head and a handle, the handle having a lower end for mounting to the head. The scraper device is attachable to and detachable from the broom in a relatively quick and simple manner without causing any damage to the 10 broom that may weaken the broom structurally. Further, the present invention relates to means for bracing the handle when the scraper device is attached to the broom.
In one aspect of the invention, the invention comprises a scraper device for attachment to a broom of the type having a head and a handle, the handle having a lower end for mounting to the head and an upper end. The scraper device comprises: a handle mounting member for connecting the scraper device to the handle, the handle mounting member defining an aperture which is sized to permit the handle to be accepted therein; a blade carrying member depending from the handle mounting member so that when the handle is mounted to the head and the 20 upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the blade carrying member extends downwards and forwards over the head; means for anchoring the scraper device when it is attached to the broom so that upward movement of the scraper device relative to the handle is restricted; and a scraper blade located along the edge of the blade carrying member opposite the handle mounting member, so that debris may be scraped from the surface by the scraper device when the orientation of the broom is reversed from that normally used for sweeping.
In this aspect of the invention, the scraper device may further comprise means, associated with the blade carrying member, for bracing the handle when the scraper device is attached to the broom. These bracing means preferably comprise 10 at least one bracing member depending from the lower surface of the blade carrying member which contacts the head of the broom in order to support the handle from the stresses which tend to break the handle at the point where it is mounted to the broom head. Suitable bracing means may be comprised of a pair of bracing members depending from the lower surface of the blade carrying member which abut against the head when the scraper device is attached to the broom. However, other arrangements including one or more bracing members are possible, so long as the handle is supported thereby.
Further, the blade carrying member may comprise at least one rib 20 positioned adjacent the scraper blade for increasing the rigidity of the scraper blade.
Further, the blade carrying member preferably depends from the handle mounting member at a depending angle measured between the upper surfaces of the handle mounting member and the blade carrying member. The handle mounting member may be resiliently rotated relative to the blade carrying member so as to alter the depending angle. The depending angle at rest may be less than the depending angle when the scraper device is attached to the broom and the blade carrying member is contacting the head, so that when the scraper device is attached to the broom, the handle mounting member is urged to rotate relative to the blade carrying member to reduce the depending angle, thus causing a gripping effect of the 10 handle mounting member against the handle. The aperture in the handle mounting member may be sized so that the handle fits snugly within the aperture in order to assist in the gripping effect. Further, the aperture may be defined by a sharp edge, in order to assist further in the gripping effect.
The handle mounting member and the blade carrying member may be formed from one piece of material. The scraper blade may be formed by the edge of the blade carrying member opposite the handle mounting member.
The anchoring means of the scraper device comprise a fastening 20 system associated with the blade carrying member which serves to secure the blade carrying member either to the head or the handle, and preferably includes one or more bolts, plugs, cables or other fasteners which couple the blade carrying member -to the head or handle without requiring modification of the broom by drilling or screwing.
Suitable anchoring means may be comprised of: the head including a first socket for mounting the handle to the head and a second socket, the sockets convergingly extending from the upper surface of the head to the lower surface of the head so that they intersect near the lower surface of the head; the blade carrying member defining a hole therein so that when the handle is mounted to the head using the first socket and the upper end of the handle is passed through the aperture and 10 the handle mounting member is positioned adjacent the lower end of the handle, the hole corresponds with the second socket; and a plug having a first end which is sized to fit within the second socket and having a second end which is larger than the hole, in order that the first end of the plug may be passed through the hole and secured within the second socket, and so that the second end of the plug will not pass through the hole and will secure the blade carrying member to the head. The second socket may be threaded and the plug may be sized and threaded so that it may be secured into the second socket and thereby secured to the head. The plug may be long enough to abut against the handle at the point of convergence of the sockets when the lower end of the handle is in the first socket and the plug is in the second 20 socket, so as to restrict the movement of the handle in the first socket. The first end of the plug may include means for restraining the handle when the lower end of the handle is in the first socket and the plug is in the second socket. The restraining means may comprise a point at the first end of the plug. Further, the restraining means may comprise a rubber pad at the first end of the plug.
Other suitable anchoring means are comprised of: a U-shaped bolt with two ends for accepting tighteners; a pair of tighteners for attaching to the ends of the U-shaped bolt; and the blade carrying member defining two openings which are sized and spaced apart from one another in order to accept the ends of the U-shaped bolt, and which are positioned next to each other along an axis which is substantially perpendicular to the axis defined by the aperture in the handle mounting member; so 10 that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the U-shaped bolt can be positioned around the handle and the ends of the U-shaped bolt can be passed through the openings in the blade carrying member and the tighteners can be attached to the ends of the U-shaped bolt and tightened in order to secure the U-shaped bolt to the handle and restrict the upward movement of the scraper device relative to the handle. The surface of the U-shaped bolt may be textured so that it may be more positively secured to the handle.
Further, the surface of the U-shaped bolt may be textured by threads that extend over substantially the entire length of the U-shaped bolt and the tighteners may be 20 threaded for attaching to the ends of the U-shaped bolt.
Still other suitable anchoring means are comprised of: a flexible cable having two ends for accepting tighteners; a pair of tighteners for attaching to the ends of the cable; and the blade carrying member defining two openings spaced apart from one another for accepting the cable therethrough and which are positioned next to each other along an axis which is substantially perpendicular to the longitudinal axis of the head when the scraper device is attached to the broom; so that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, the cable can be successively passed through the openings and about the 10 head and the tighteners can be attached to the ends of the cable and tightened in order to secure the cable about the head and restrict the upward movement of the scraper device relative to the handle. The blade carrying member may define two pairs of openings spaced apart from one another and positioned such that when the handle is mounted to the head and the upper end of the handle is passed through the aperture and the handle mounting member is positioned adjacent the lower end of the handle, one pair of openings is located adjacent to the head on either side of the handle. The ends of the cable may be threaded for accepting the tighteners and the tighteners may be threaded for attaching to the ends of the cable.
The scraper device may be further comprised of a cleaning flange depending from the lower surface of the blade carrying member substantially parallel with the scraper blade such that when the scraper device is attached to the broom, -the cleaning flange is directed towards the head for limiting debris from being trapped between the head and the scraper device. The cleaning flange may be welded to the lower surface of the blade carrying member.

BEST MODE OF CARRYING OUT INVENTION
Referring to Figures 1 through 3, the invention is comprised of a scraper device (20) for attachment to a broom (22). The broom (22) is of a type 20 conventionally known as a push broom or brush broom and having an elongated head (24) and a handle (26). The head (24) is comprised of an upper surface (28) and a lower surface (30) having attached bristles (32) for sweeping. The handle (26) -is conventionally a pole having an upper end (34) for gripping by the user of the broom (22) and a lower end (36) for mounting to the upper surface (28) of the head (24). The handle (26) typically extends from the upper surface (28) of the head (24) at an angle from vertical orientation in order to allow the user of the broom (22) to grip the upper end (34) of the handle (26) while maintaining the contact of the bristles (32) with the surface to be cleaned.
The scraper device (20) is comprised of a handle mounting member (38), a blade carrying member (40), a scraper blade (42) and means for anchoring 10 the scraper device. The handle mounting member (38) has an upper surface (44) and a lower surface (46) and defines an aperture (48). The aperture (48) is sized to permit the handle (26) to be accepted therein.
Preferably, the blade carrying member (40) has an upper edge (50), a lower edge (52) and a first and second side edge (54, 56). Further, the blade carrying member (40) has an upper surface (58) and a lower surface (60). In the preferred embodiment, the upper edge (50) of the blade carrying member (40) is connected to the handle mounting member (38) such that the blade carrying member (40) depends from the handle mounting member (38).
When the handle (26) is mounted to the head (24), the upper end (34) of the handle (26) may be passed through the aperture (48) in the handle mounting member (38) from the lower surface (46) of the handle mounting member (38) to the upper surface (44) of the handle mounting member (38) and the handle mounting member (38) may be positioned adjacent the lower end (36) of the handle (26).
When the handle mounting member (38) is so positioned, the blade carrying member (40) depends from the handle mounting member (38) in a manner so that the blade carrying member (40) extends downward, towards the bristles (32), and forwards over the head (24) of the broom (22). The blade carrying member (40) is positioned so that when the handle (26) of the broom (22) is gripped by the user in a manner for sweeping, with the bristles (32) in contact with the surface to be cleaned, the blade 10 carrying member (40) extends forwards, away from the user on the side of the handle (26) and the head (24) opposite, or not facing, the user.
The blade carrying member (40) depends from the handle mounting member (38) at a depending angle. The depending angle is measured between the upper surface (44) of the handle mounting member (38) and the upper surface (58) of the blade carrying member (40). The point of connection between the handle mounting member (38) and the blade carrying member (40) allows the handle mounting member (38) to be resiliently rotated relative to the blade carrying member (40) so that the depending angle may be altered. In the preferred embodiment, the 20 handle mounting member (38) and the blade carrying member (40) are integral.
They are formed from one piece of a resilient material which allows for the resilient rotation of the handle mounting member (38) relative to the blade carrying member -(40). In the preferred embodiment, the handle mounting member (38) and the blade carrying member (40) are constructed out of a single piece of sheet metal which is bent to form the depending angle. Alternatively, the handle mounting member (38) and the blade carrying member (40) may be molded from a resilient plastic into a single piece defining the depending angle.
When the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26) and the means for anchoring the scraper device (20) are not employed, the blade carrying member (40) is at rest. When at rest, the 10 depending angle is such that the blade carrying member (40) is held a spaced distance from the head (24). When the means for anchoring the scraper device (20) are employed, the handle mounting member (38) is resiliently rotated relative to the blade carrying member (40), increasing the depending angle, and the lower surface (60) of the blade carrying member (40) is brought into contact with the head (24).
Thus the depending angle at rest is less than the depending angle when the blade carrying member (40) is contacting the head (24). The depending angle at rest may vary depending upon, amongst other factors, the type and size of the head (24) of the broom (22), the type of material from which the handle mounting member (38) and the blade carrying member (40) are constructed, and the manner of connection 20 between the handle mounting member (38) and the blade carrying member (40).
However, in the preferred embodiment, the depending angle at rest is approximately 40 degrees.
As a result of the varying depending angle and the resilient connection between the handle mounting member (38) and the blade carrying member (40), when the scraper device (20) is attached to the broom (22) by the anchoring means, the handle mounting member (38) is urged to rotate relative to the blade carrying member (40) to reduce the depending angle. This causes a gripping effect of the handle mounting member (38) against the handle (26). The gripping effect assists in minimizing unwanted movement or rotation of the handle (26) relative to the head (24). For example, the head (24) may include a threaded socket for accepting a threaded lower end (36) of the handle (26). During use, the handle (26) may tend to 10 loosen up and unscrew from the socket in the head (24). The gripping effect aids in minimizing the rotation of the handle (26) relative to the head (24), thus assisting in maintaining a tight fit or connection between the head (24) and the handle (26).
Preferably, to assist in the gripping effect, the aperture (48) is sized such that the handle (26) fits snugly within the aperture (48) yet still allowing for the handle (26) to pass through the aperture (48) substantially unimpeded. To further assist in the gripping effect, the aperture (48) is defined by a sharp edge.
A scraper blade (42) is located along the lower edge (52) of the blade 20 carrying member (40) opposite to the handle mounting member (38). In the preferred embodiment, the scraper blade (42) is integral with the blade carrying member (40) and is formed by the lower edge (52) of the blade carrying member (40). Thus, the scraper blade (42) is also constructed of sheet metal in the preferred embodiment.
Where the blade carrying member (40) is made of another material such as plastic, it is preferred to mount a scraper blade (42) constructed of metal along the lower edge (52) of the blade carrying member (40) to improve the wear of the scraper device (20). Further, the blade carrying member includes a rib (62) for increasing the rigidity of the scraper blade (42). The rib (62) is located at the lower edge (52) of the blade carrying member (40) such that it is positioned adjacent the scraper blade (42) and has a longitudinal axis which is substantially parallel with the longitudinal axis of the scraper blade (42). A greater number of ribs (62) may be used as required to 10 increase the rigidity of the scraper blade (42).
When the scraper device (20) is attached to the broom (22) and the anchoring means are employed, the scraper blade (42) is out of contact with the suRace to be cleaned during normal use of the broom (22). The scraper blade (42) does not inteRere with the normal use of the broom (22). The scraper device (20) is utilized by reversing the orientation of the broom (22) from that normally used for sweeping. The upper suRace (58) of the blade carrying member (40) faces and is adjacent to the suRace to be cleaned by the scraper device (20) and the bristles (32) are out of contact with the suRace to be cleaned.
During use of the scraper device (20), debris scraped from the suRace being cleaned may become trapped between the bristles (32) or the head (24) and the scraper device (20). Further, debris may become similarly trapped when usingthe broom (22) for sweeping. As a result, in the preferred embodiment, the scraper device (20) includes a cleaning flange (64). The cleaning flange (64) depends from the lower surface (60) of the blade carrying member (40) at its lower edge (52).Further, the longitudinal axis of the cleaning flange (64) is substantially parallel with the scraper blade (42). As a result, when the scraper device (20) is attached to the broom (22), the cleaning flange (64) is directed towards the head (24). Thus, the cleaning flange (64) blocks the space between the scraper device (20) and the head (24) and limits any debris being trapped therebetween. In the preferred embodiment, the cleaning flange (64) is constructed of metal similar to the blade carrying member (40) and is welded to the lower surface (60) of the blade carrying member (40).
Further, the scraper device (20) includes means for bracing the handle (26) when the scraper device (20) is attached to the broom (22). In the preferred embodiment, the bracing means are a pair of bracing members (66, 68) which depend from the lower surface (60) of the blade carrying member (40). The bracing members (66, 68) are flanges or protrusions from the blade carrying member (40). A
first bracing member (66) is located adjacent the first side edge (54) of the blade carrying member (40). A second bracing member (68) is located adjacent the second side edge (56) of the blade carrying member (40). Both bracing members (66, 68) extend from the upper edge (50) of the blade carrying member (40), where the blade carrying member (40) is connected to the handle mounting member (38), and along 2l27294 the side edges (54, 56) of the blade carrying member (40). When the scraper device (20) is attached to the broom (22), and the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the bracing members (66, 68) abut against the upper surface (28) of the head (24) so that the bracing members (66, 68) brace the handle (26). Further, the abutment of the bracing members (66, 68) against the head (24) restricts the downward movement, or movement away from the upper end (34) of the handle (26), of the scraper device (20) relative to the handle (26).
In the preferred embodiment, the bracing members (66, 68) are integral with the blade carrying member (40). The blade carrying member (40), including the bracing members (66, 68) are cut from sheet metal. The bracing members (66, 68) are then bent or folded towards the lower surface (60) of the blade carrying member (40) to depend therefrom. Although the bracing means are preferably comprised of two bracing members (66, 68) as described above, other arrangements including one or more bracing members are possible as long as the bracing member depends from the lower surface (60) of the blade carrying member (40) and contacts the head (24) in order to support the handle (26) from the stresses which tend to break the handle (26) at the point where it is mounted to the head (24).
The preferred embodiment further includes a hanging hole (72). The hanging hole (72) is defined by the blade carrying member (40) and is located adjacent the lower edge (52) of the blade carrying member (40). Further, the hanging hole (72) is located approximately midway between the first side edge (54) and the second side edge (56) of the blade carrying member (40). When the scraper device (20) is attached to the broom (22) and the anchoring means are employed, the hanging hole (72) is used for storing the broom (22) by placing the hanging hole (72) over a hook, nail or similar protrusion located on a wall. In this manner, the broom (22) with the attached scraper device (20) may be safely and conveniently stored.
As stated above, the scraper device (20) includes means for anchoring 10 the scraper device (20) when it is attached to the broom (22). The anchoring means act to restrict the upward movement of the scraper device (20) relative to the handle (26), or in other words, the movement of the scraper device (20) towards the upper end (34) of the handle (26). Further, the anchoring means assist in the gripping effect described above. The anchoring means are comprised of a fastening system associated with the blade carrying member (40) for securing the blade carrying member (40) to either the head (24) or the handle (26) of the broom (22). Further, the anchoring means include one or more bolts, plugs, cables or other fasteners which couple the blade carrying member (40) to the broom (22) without requiring modification of the broom (22) by drilling or screwing.
In the preferred embodiment, as shown in Figures 1 through 3, the anchoring means are comprised of a fastener, being a U-shaped bolt (74), a pair of tighteners (76, 78) and the blade carrying member (40) defining a first opening (80) and a second opening (82). The first and second openings (80, 82) in the blade carrying member (40) are sized and spaced apart from one another in order to accept the ends of the U-shaped bolt (74) therein. Further, the first and second openings (80, 82) are positioned next to each other along an axis which is substantially perpendicular to the axis defined by the aperture (48) in the handle mounting member (38). Finally, when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the first and second openings (80, 82) are located between the handle mounting member (38) and the head (24) of the broom (22).
As a result of the placement of the first and second openings (80, 82), when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the U-shaped bolt (74) can be positioned around the handle (26) and the ends of the U-shaped bolt (74) can be passed from the lower surface (60) of the blade carrying member (40), through the first and second openings (80, 82) to the upper surface (58) of the blade carrying member (40). The ends of the U-shaped bolt (74) are threaded for accepting the tighteners (76, 78). The tighteners (76, 78) are compatibly threaded for attaching to the ends of the U-shaped bolt (74). Thus, when the U-shaped bolt (74) is in position around the handle (26), the tighteners (76, 20 78) can be attached to the ends of the U-shaped bolt (74) and tightened against the upper surface (58) of the blade carrying member (40) in order to secure the U-shaped bolt (74) to the handle (26) and restrict the upward movement of the scraper device (20) relative to the handle (26). To more positively secure the U-shaped bolt (74) to the handle (26), the surface of the U-shaped bolt (74) is textured by threads that extend over substantially the entire length of the U-shaped bolt (74).
In a second embodiment of the scraper device (20), as shown in Figures 4 through 6, the anchoring means are comprised of a fastener, being a flexible cable (84), a pair of tighteners (86, 88) and the blade carrying member (40) defining a first and second pair of openings (90, 92). More or fewer openings may be used as required to anchor the scraper device (20). With respect to each pair of 10 openings in the preferred form of the second embodiment, the two openings are spaced apart from one another and are positioned next to each other along an axis which is substantially perpendicular to the longitudinal axis of the head (24) when the scraper device (20) is attached to the broom (22). Further, the first and second pairs of openings (90, 92) are spaced apart from one another and positioned such that when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), one pair of openings is located adjacent to the head (24) on either side of the handle (26). Thus, the first pair of openings (90) is located between the handle (26) and the first side edge (54) of the blade carrying member (40) and the second pair of openings (92) is located between the handle (26) and the second side 20 edge (56).
As a result of the placement of the pairs of openings (90, 92), when the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the ends of the cable (84) can be successively passed through the openings(90, 92) and about the head (24). For example, the cable (84) may pass from the upper surface (58) of the blade carrying member (40), through the opening in the first pair of openings (90) nearest to the upper edge (50) of the blade carrying member (40), around the head (24), through the opening in the first pair of openings (90) nearest to the lower edge (52) of the blade carrying member (40). The cable (84)then passes across the upper surface (58) of the blade carrying member (40), through the opening in the second pair of openings (92) nearest to the lower edge (52) of the blade carrying member (40), around the head (24), and through the opening in the second pair of openings (92) nearest to the upper edge (50) of the blade carrying member (40) to the upper surface (58) of the blade carrying member (40). The specific passing of the cable (84) may vary as long as the cable (84) loops around the head (24) and the ends of the cable (84) are located on the upper surface (58) of the blade carrying member (40) for ease of access to them.
The ends of the cable (84) are threaded for accepting the tighteners (86, 88). The tighteners (86, 88) are compatibly threaded for attaching to the ends of the cable (84). Thus, when the cable (84) is in position around the head (24), the tighteners (86, 88) can be attached to the ends of the cable (84) and tightened against the upper surface (58) of the blade carrying member (40) in order to secure 212729~
the cable (84) about the head (24) and restrict the upward movement of the scraper device (20) relative to the handle (26).
In a third embodiment of the scraper device (20), as shown in Figures 7 through 9, the anchoring means are comprised of the head (24) including a first socket (94) and a second socket (96), a hole (98) in the blade carrying member (40) and a fastener, being a plug (100). As shown in Figure 8, the sockets (94, 96) convergingly extend from the upper surface (28) of the head (24) to the lower surface (30) of the head (24) so that they intersect near the lower surface (30). In a conventional broom, the two sockets (94, 96) are substantially identical and at approximately right angles to each other. Thus, a V-shaped passage is formed in the broom (22). Both sockets (94, 96) are threaded such that a threaded lower end (36) of the handle (26) may be mounted in either socket (94, 96) as desired. In the preferred form of the third embodiment, the lower end (36) of the handle (26) ismounted in the first socket (94).
As stated, the blade carrying member (40) defines a hole (98). When the handle (26) is mounted to the head (24) using the first socket (94), and the upper end (34) of the handle (26) is passed through the aperture (48) and the handle mounting member (38) is positioned adjacent the lower end (36) of the handle (26), the hole (98) corresponds with the second socket (96). The second socket (96) is 212729~
-threaded for receiving the plug (100) and the plug (100) is sized and threaded so that it may be secured into the second socket (96) and thereby secured to the head (24).
The plug (100) has a first end (102) which is sized to fit within the second socket (96) and a second end (104) which is larger than the hole (98). Thus, in use, the first end (102) of the plug (100) is passed through the hole (98) and secured within the second socket (96) by tightening the plug (100). The second end (104) of the plug (100) will not pass through the hole (98) and therefore secures the blade carrying member (40) to the head (24).
Further, the plug (100) is long enough for the first end (102) to abut against the handle (26) at the point of convergence of the first and second sockets (94, 96) when the lower end (36) of the handle (26) is in the first socket (94) and the plug (100) is in the second socket (96). The abutment of the plug (100) against the handle (26) restricts the movement of the handle (26) in the first socket (94) thus inhibiting the loosening of the handle (26) during use of the broom (22) or scraper device (20). To further restrict movement, the first end (102) of the plug (100)includes means for restraining the handle (26). The restraining means are comprised of a point (106) at the first end (102) of the plug (100). The point (106) engages the handle (26) when the lower end (36) of the handle (26) is in the first socket (94) and the plug (100) is in the second socket (96), and thereby restricts its movement.
Other restraining means may also be used such as a rubber pad (not shown) at thefirst end (102) of the plug (100).
