Technical Field

[0003] The present invention relates to cleaning devices, and in particular to a cleaning device having a tooth member for improved cleaning. Background Art

[0004] There are many types of cleaning devices used for different purposes. Some examples include brooms, which are commonly used to sweep hard surfaces; mops, which are used to wipe hard surfaces; vacuum cleaners, which are used to clean different types of surfaces by using suction; and lint removers, which are used to remove lint and hair from surfaces using an adhesive.

[0005] While each of the above cleaning devices is generally useful for its intended purpose, it is difficult to find a cleaning device that can remove small fiber debris, such as pet hair, human hair, and lint that is lodged in fibrous surfaces. For example, the surfaces of clothing, carpets, furniture, car seats, car mats, and door mats include a depth in which these lightweight fiber debris can become entangled and lodged. Even with a vacuum cleaner, this fiber debris is difficult to remove because the debris is lodged deeply in the surface and in the fibers of the surface. Prior art vacuum cleaners and vacuum cleaner attachments for cleaning fibrous surfaces include only bristles that help remove debris from the surface, but they are ineffective.

[0006] Additionally, shedding pets, such as cats and dogs, tend to shed hair in the house, requiring the homeowner to continually clean the shed pet hair. While brushes can collect hair directly from the pet, this requires cleaning the brush after use and cleaning the removed hair around the pet, which is messy and time consuming.

[0007] Therefore, there is a need for a simple and affordable cleaning device that can effectively remove light fiber debris from fiber surfaces as a stand-alone device or attachment for a vacuum cleaner.

[0008] Rapid urbanization and growing industrialization have also led to a significant increase in construction activities. Dust and debris generated by these construction activities accumulate in living spaces and are a major cause of health problems, prompting frequent cleaning of living and working spaces. In such a scenario, the use of vacuum cleaning machines in homes has become very common almost everywhere.

[0009] Typically, a vacuum cleaner is an electrically driven device that creates suction to remove dust and debris from surfaces such as floors, upholstery, fabrics, and other surfaces or different materials. Vacuum cleaners used in homes and industries come in a variety of sizes and shapes, from battery-powered handheld devices to larger wheel-driven types. Vacuum cleaners create negative pressure to create a partial vacuum, thereby collecting dust and dirt from floors and other surfaces, as well as fiber debris such as lint, hair, etc.

[0010] However, when cleaning fibrous materials such as carpets and tapestries, conventional vacuum cleaners are unable to remove debris of fibrous materials that are lodged deep below the top surface of the area or object intended to be cleaned. For example, clothing, carpets, furniture, car seats, car mats, and door mats include a depth in which such lightweight fibrous debris may become entangled and lodged below the top surface. Even with the use of a vacuum cleaner, such fibrous debris is difficult to remove because the debris is lodged deep within the material and within the fibers of the material to be cleaned.

[0011] Therefore, various attachments are provided for attaching to vacuum cleaners to not only clean smaller areas or hard to reach areas (such as under furniture or in a car), but also to help remove and dislodge debris from deep in the fiber material and within the fibers of the material. However, conventional attachments for cleaning fiber surfaces only include bristles to help remove debris from the material, but they are ineffective.

[0012] Some conventional techniques also provide lint traps attached to the suction head of a vacuum cleaner to remove lint and hair from the fiber material. These lint traps have an adhesive effect that captures lint and hair only from the top surface of the fiber material. Therefore, debris accumulated below the top surface remains accumulated therein.

[0013] With the vacuum attachments described above, debris also tends to accumulate at the entry point of the attachment, thus not only limiting suction but also requiring the user to remove the debris from the entry point.

[0014] In addition to fibrous materials, similar problems exist for cleaning pets with hair. Shedding pets, such as cats and dogs, tend to shed hair in the house, requiring the homeowner to constantly clean the shed pet hair. While brushes can be used to collect hair directly from the pet, this requires cleaning the brush after use and cleaning the removed hair around the pet, which is messy and time consuming. The same problem exists for cleaning materials with very long fibers, such as fur coats and fur carpets.

[0015] Therefore, a need exists for a vacuum cleaner or vacuum cleaner attachment that provides an effective and convenient means for cleaning debris from fibrous materials and for combing and collecting pet hair. Summary of the invention

[0056] Tooth components

[0057] Figure 1 A perspective view of an attachment or tooth member of an elongated member 10 for a cleaning device (such as a suction head of a vacuum cleaner or a head member of a cleaning device) according to an embodiment of the present invention is shown. The attachment or tooth member is an elongated member 10 having a plurality of teeth and adapted to be fixed to the suction head of a vacuum cleaner or a head member of a cleaning device. In an embodiment, the elongated member 10 has opposing surfaces that allow the member 10 to be attached to the suction head or the head member of the cleaning device from one side of the member 10 and to clean fiber debris from the other side of the member 10, as will be described in detail below. When referring to the attachment as a component of the suction head of a vacuum machine or the head member of a cleaning device that cleans a surface under working conditions, these surfaces are also referred to as attachment surfaces (received by the suction head or the head member of the cleaning device) and contact surfaces (contacting the surface to be cleaned), respectively.

[0058] In this embodiment, the elongated member 10 has a substantially circular cross-sectional area. However, the elongated member 10 may also have different cross-sections, such as square, rectangular and oval cross-sections. The elongated member 10 is made of a strong material such as metal, rigid plastic, polymer or reinforced material. The choice of material for the elongated member 10 depends on considerations such as weight and durability. In this embodiment, the elongated member 10 is constructed of aluminum.

[0059] In this embodiment, the elongated member 10 is processed so that the radially outer portion 12 of the elongated member 10 is equipped with a plurality of grooves 14 that continuously extend or surround the member 10, thereby forming a plurality of flanges 16 therebetween. The flanges 16 also continuously extend or surround the elongated member 10. In this embodiment, the flanges 16 have a substantially flat outer surface and are equally spaced. Therefore, potential contact with any sharp edge is avoided, providing safety for the user. In addition, based on testing, it has been found that the extremely small spacing between the flanges 16 produces the best results for collecting small fiber debris (such as hair and lint). However, without departing from the spirit and scope of the present invention, the spacing between the grooves 14 and the flanges 16 can be varied.

[0060] Still refer to Figure 1 , the flange 16 on the top and bottom sides of the member 10 includes a portion extending radially outward from the rest of the flange 16. Specifically, a pair of spaced flange extensions or protrusions 18 are provided on each side, forming relative channels 20, 22 between them. A pair of protrusions 18 on each opposite side of the elongated member 10 form a surface (i.e., an attachment surface) required for attachment to the head member of the suction head or cleaning device on one side of the member 10, and a surface (i.e., a contact surface) contacting the surface to be cleaned from the other side of the member 10. Specifically, as shown in the figure, the shape and size of the top channel 20 are determined to be used to receive the head member of the suction head or cleaning device, and the bottom channel 22 contacts the surface to be cleaned at a certain angle. It should be noted that, according to the size and shape of the engaging portion of the head member of the suction head or cleaning device, the top channel 20 can take other sizes and shapes. Moreover, in this embodiment, the top channel 20 and the bottom channel 22 are positioned directly opposite to each other. However, the top channel 20 and the bottom channel 22 may be positioned differently depending on the configuration and the angle of attack of the suction head or head member of the cleaning device.

[0061] In this embodiment, each protrusion 18 is substantially semicircular in shape to minimize unnecessary friction between the flange extension 18 and the cleaning surface when in use. That is, the semicircular shape provides a minimal but sufficient contact area to ensure that the member 10 can move smoothly along the cleaning surface while effectively cleaning. Figure 1The shape of the protrusion 18 shown also minimizes the risk of damaging the cleaning surface. However, the flange extension or protrusion 18 may take other shapes, such as triangular or square, for example. Fig.25 and Fig.26 As shown. In addition, since generally only the protrusions 18 will contact the cleaning surface, the rest of the flange 16 can be machined solid, rather than having flanges 16. In any case, it is preferred that the bottom channel 22 is parallel to the cleaning surface when in use to maximize the efficiency of the cleaning device. That is, cleaning is most effective when the protrusions 18 engage the cleaning surface at right angles. Depending on the application, for example, a thin tapestry compared to a thick carpet, the length of the protrusions 18 can vary, such as Fig.25 and Fig.26 shown.

[0062] In this embodiment, the overall cross-sectional dimensions of the elongate member 10 are 8mm x 8mm; the flanges 16 are spaced 0.52mm apart; the flange extensions 18 are spaced 1.33mm apart, and each flange extension 18 is 1.09mm wide. However, the dimensions may vary depending on the application.

[0063] See now Figure 2 and Figure 3 , a second embodiment of an attachment or tooth member 30 of the present invention is shown. Similar to the first embodiment described above, the tooth member 30 is made of a solid material such as metal and has a substantially circular cross-section. Also in this embodiment, the tooth member 30 (hereinafter interchangeably referred to as the elongated member) is made of aluminum because it is durable and lightweight. However, other materials such as steel and plastics may be used. Moreover, without departing from the spirit and scope of the present invention, the cross-section of the elongated member 30 may take other sizes and shapes, such as square, rectangular or oval. The elongated member 30 is processed so that the radially outer portion 32 of the elongated member 30 is provided with a plurality of grooves 34, thereby forming a plurality of flanges 36 therebetween. In this embodiment, these flanges 36 are substantially triangular in cross-section and have substantially pointed outer edges and are equidistantly spaced apart.

[0064] Based on testing, it has been found that very small spacing between the flanges 36 produces the best results in collecting small fiber debris (such as hair and lint). However, the spacing between the grooves 34 and the flanges 36 may be varied without departing from the spirit and scope of the present invention. Figure 3 As shown, the height of the flange 36 in this embodiment is less than the height of the flange 16 in the first embodiment 10. This is to ensure that the cleaning surface is not damaged when the cleaning device is in use.

[0065] Still reference Figure 2 and Figure 3In this embodiment, the groove 34 and the flange 36 are interrupted on the top and bottom sides of the tooth member 30. Figure 2 As shown, the top side includes a substantially flat top channel 38 having a bottom surface or attachment surface, and the bottom side directly opposite the top side includes a substantially flat bottom channel 40 having a bottom surface or contact surface. As will be described in more detail below, the shape and size of the top channel 38 are determined to receive the body of the suction head or any other cleaning device. Therefore, depending on the size and shape of the engaging portion of the body of the suction head or any other cleaning device, the top channel 38 can adopt other sizes and shapes. Moreover, in this embodiment, the top channel 38 and the bottom channel 40 are positioned directly opposite each other; however, the top channel 38 and the bottom channel 40 can be positioned differently depending on the configuration of the head component.

[0066] In this embodiment, the bottom channel 40 is sized so that its bottom surface 42 is positioned below the lowermost portion 44 of the groove 34. Moreover, the width of the bottom channel 40 is minimal to ensure user safety. Therefore, the outer edge of the flange 36 extending from the bottom channel 40 forms a flange extension or protrusion 48, which engages the cleaning surface at a preferred angle. Preferably, the bottom channel 40 is perpendicular to the cleaning surface when in use to maximize the efficiency of the cleaning device. That is, cleaning is most effective when the protrusion 48 engages the cleaning surface at a right angle. Depending on the application, for example, a thin tapestry compared to a thick carpet, the length of the flange extension 48 may vary.

[0067] Reference Figure 3 , a valley 49 is formed adjacent to each flange extension 48 and extends along the tooth member 30. In this embodiment, each valley 49 is substantially narrow and triangular in shape. The valley 49 also helps to loosen debris and collect fiber debris from the material being cleaned. As will be described below, the size and size of each valley can vary depending on the application.

[0068] In this embodiment, tooth member 30 has a cross-sectional radius of 3.57 mm; the top channel is 3 mm wide; the bottom channel is 1.8 mm wide; the valley is 1.09 mm×0.8 mm; the flanges 36 are spaced 1.02 mm apart; the flanges have a height of 0.75 mm; and each flange 36 has a pitch angle of 0.87.

[0069] Reference Figure 4In another embodiment, the tooth member or elongated member 50 is substantially similar to the tooth member or elongated member 30 described above, but with some exceptions. First, the ends of the elongated member 50 are inclined so as to eliminate any sharp edges. Second, the width of the valley 49 is wider than the valley 49 of the elongated member 30. The elongated member 50 includes a top channel 40 having a contact surface and a relative channel having an attachment surface. A plurality of radial protrusions or flanges 58 extend from the contact surface (i.e., the surface that contacts the cleaning surface). The radial protrusions 58 are formed in a linear orientation along the length of the elongated member 50 and have a triangular groove or valley 59 that runs through the length of the member 50.

[0070] The elongated member 10, 30, 50 is fixed to a support member 122 of a suction head or a head member of a cleaning device, such as in Figure 4 , Fig.11 , Fig.13 and Fig.18 Specifically, the support member 122 extending from the periphery of the inlet of the suction head is fixed to the channels 20, 38 of the elongated members 10, 30, 50 by snap fit. Additionally or alternatively, the channels 20, 38 can be fixed to the support member 122 by an adhesive. Similarly, the distal end 258 ( Fig.18 ), proximal ends 260, 262 ( Fig.11 , Fig.13 and Fig.18 ) or the joint member 190 ( Fig.16 ) is secured to the channel 20, 38 of the elongate member 10, 30, 50 by a snap fit. Additionally or alternatively, the channel 20, 38 may be secured by an adhesive.

[0071] Suction heads / vacuum attachments

[0072] In another aspect, the present invention relates to an attachment or suction head for a vacuum cleaning machine for collecting debris, including fiber debris, from fibrous materials without using any special means. In addition, the disclosed invention facilitates complete removal of debris in a time-effective and efficient manner.

[0073] Figures 4 to 6An embodiment of a cleaning device of a suction head 101 used as a vacuum cleaner according to the present invention is shown, wherein a tooth member or an elongated member 50 is used as an attachment. In this embodiment, the suction head 101 includes a body 112 and a head component 118, and the body 112 has a hollow tube 120, and the head component 118 has a top wall 118a and a relative bottom wall 118b formed integrally together. The head component 118 is attached to the tube 120 substantially at a right angle to achieve maximum efficiency. The body 112 includes an outlet 114 at the open end of the hollow tube 120 and an inlet 116 at the mouth of the head component 118. The outlet 114 is configured to be attached to the inlet of a hose or an extension nozzle of a vacuum cleaner. The mouth of the head component 118 is constructed to be wide enough to receive the elongated member 50 longitudinally. The tube 120 is formed integrally with the head component 118.

[0074] The suction head 101 also includes a receiving portion including a support member 122 adapted to receive a corresponding attachment surface of the elongated member 50 (ie, Figure 2 and 3 38) for fixing the elongated member 50 at the mouth of the head part 118 of the suction head 101 to the bottom wall 118b. In this embodiment, the support member 122 (such as Figure 4 As shown in FIG. 1 , the bottom wall 118b of the head member 118 extends from the lower edge of the bottom wall 118b of the head member 118. Figure 4 As shown, the bottom surface of the bottom wall 118b of the head member 118 includes a cutout 123 extending along the length of the bottom wall 118b to accommodate a bottom portion of the length of the tooth member 50. Thus, the elongated member 50 is exposed to the surface to be cleaned to the greatest extent possible.

[0075] The shape and size of the support member 122 are determined to receive the attachment surface (i.e., channel) of the elongated member 50. However, the support member 122 can be shaped differently to receive the elongated members of different configurations as described in the present disclosure. For example, in an alternative embodiment, the support member 122 can be U-shaped to receive the corresponding U-shaped channel of the elongated member. In another alternative, another support member can extend along the length of the edge of the head component top wall 118a and have an elongated member attached thereto. As a result, multiple elongated members can scrape the cleaning surface to further increase cleaning efficiency.

[0076] The suction head 101 can be constructed as an integral structure by injection molding technology using materials including plastics. Alternatively, other materials, such as metals and composite materials, can also be used.

[0077] In operation, the user holds the suction head 101 at the tube 120 and engages the inlet 116 on the cleaning surface. The user pulls the suction head 101 toward the user so that the flange 58 of the elongated member 50 scrapes the cleaning surface and the material therein. During this motion, debris is removed from the material being cleaned and travels through the inlet 116 and into the vacuum machine. The user can also push the suction head 101 during use, but optimal results may not be achieved.

[0078] Reference Figures 7 to 9 , shows a perspective view of another embodiment of a cleaning device according to another embodiment of the present invention, which is used as a suction head 105 of a vacuum cleaner. The suction head 105 is adapted to receive another embodiment of the elongated member or tooth member 70. The suction head 105 includes a hollow body 130 having an outlet 114 and an inlet 116, similar to the previous suction head embodiment 101. However, the body 130 is linear in shape, rather than being as in the embodiment of the present invention. Figures 4 to 6 The suction head embodiment 101 shown in FIG. 1 has an angle between the hollow tube 120 and the head component 118. The outlet 114 is adapted to be attached to the inlet of a hose or an extension nozzle of a vacuum cleaner, while the inlet 116 is configured to have a mouth wide enough to receive the elongated member 70 longitudinally.

[0079] The body 130 is constructed with a front wall 138 and a rear wall 140 having similar structural dimensions, except that the front wall 138 extends lower than the rear wall 140, as shown in FIG. Figure 8 and Fig. 9 As shown. This is to contain fiber debris accumulated between the elongated member 70 and the rear wall 140 during the cleaning process. Specifically, in use, the user pulls the suction head 105 through the cleaning surface or material, wherein the front wall 138 faces upward. Therefore, fiber debris will accumulate between the elongated member 70 and the rear wall 140. In addition, the body 130 includes a support member in the form of a side flange 124, which extends from the opposite side wall of the mouth at the entrance 116. The side flange 124 has a hole 126 for receiving a fastener 128 therethrough to assemble the elongated member 70 on the mouth of the suction head. In this embodiment, the fastener 128 is a screw having a threaded end and a bolt attached to the threaded end.

[0080] refer to Figure 8 and Fig. 9 , the elongated member 70 includes a shaft 141 extending between the side flanges 124 and having a through hole along its length for receiving a fastener 128. The shaft 141 is fixed in a substantially fixed position, wherein a biasing member 143 is positioned at each end of the shaft 141 against the side flanges 124. In this way, the rotation of the shaft 141 is limited, but some leeway is given to avoid tangling when the suction head 105 is in use.

[0081] Further in Figures 7 to 9 1, a plurality of radial protrusions or flanges 134 extend from the shaft 141 along the length of the shaft 141. Each protrusion or flange 134 is similar to a claw-like structure for removing and extracting any fiber debris (such as lint and shed hair) from the fiber surface. In this embodiment, the claw-like structures are equally spaced along the length of the elongated member 70. In operation, the tips of the plurality of radial protrusions 134 of the suction head 105 form substantially right angles with the surface or material to be cleaned, thereby forming a suitable angle of attack, which results in effective displacement of fiber debris when it is pulled into the vacuum cleaner.

[0082] The suction head 105 of this embodiment is ideal for cleaning pet hair or collecting loose pet hair directly from a pet using the vacuum action of a vacuum cleaner. In addition, the suction head or cleaning device 105 is configured to comb pet hair. This further prevents hair from falling into the surrounding environment due to the suction force of the vacuum cleaner. The suction head 105 is also very suitable for cleaning fur materials, such as fur carpets and outerwear with longer fibers. The suction head 105 can be constructed as an integral structure using materials including plastics via injection molding technology. Alternatively, other materials, such as metals and composite materials, can also be used.

[0083] The cleaning devices 101, 105 shown in the drawings and described above can also be used manually. For example, an extension such as a handle or broomstick can be attached to the outlet 114 so that a user can manually use the cleaning device 101, 105 without suction from a vacuum cleaner. In this case, the user will manually remove the debris collected during use from the inlet area 116.

[0084] Head component

[0085] refer to Figures 10 to 12 , shows a first embodiment of a head member 250 of the present invention. Generally, the head member 250 includes a base member 252 at a lower portion thereof, wherein a support member 254 is integrally formed with and extends upwardly from the base member 252. An extension member 256 extends upwardly from an upper portion of the support member 254 and is integrally formed therewith.

[0086] The base member 252 is substantially planar and extends transversely substantially the length of the tooth members 10, 30. The base member 252 includes a free transverse distal end 258 and an opposite transverse proximal end 260 extending downwardly at an angle.

[0087] The support member 254 also extends transversely above the base member 252 at an acute angle substantially the length of the tooth member 10, 30. The support member 254 includes a transverse proximal end 262 that overlaps and is integrally formed with the transverse proximal end 260 of the angled base member. Depending on the angle of the overlapping proximal ends 260, 262, the support member 254 can be configured at any angle to the base member 252. The support member 254 is further supported to the base member 252 by a support flange 266 that is integrally formed between the support member 254 and the base member 252, as shown in FIG. Fig.12 As shown. The support member 254 also includes a lateral distal end 264 formed integrally with the extension member 256 to further strengthen the head member 250. In this embodiment, the angle of the overlapping proximal ends 260, 262 relative to the flat portion of the base member 252 is between 48 degrees and 78 degrees, and the extension member 256 is configured to be at a right angle relative to the flat portion of the base member 252. This allows the user to have enough leeway to manually adjust the cleaning device so that the flange extensions or lips 18, 48 of the corresponding tooth members 10, 30 are perpendicular or nearly perpendicular to the cleaning surface without discomfort during use. When using an extendable handle member as described below, this adjustment may be necessary depending on the height of the user.

[0088] Still reference Figures 10 to 12 , the head member 250 is configured to receive two tooth members. Fig.10 and Fig.12 As shown, the tooth member 10 is attached to the overlapping proximal ends 260, 262 by a snap fit or friction fit. Specifically, the size and shape of the overlapping proximal ends 260, 262 are substantially the same as the top channel 20, so that a substantially permanent engagement is formed. Similarly, as shown in FIG. Fig.11 As shown, the tooth member 30 of the second embodiment can be snap-fit ​​or friction-fit by attaching the top channel 238 to the overlapping proximal ends 260, 262. In another embodiment, as shown in FIG. Fig.11 As shown, the tooth member 30 can be attached to the distal end 258 of the base member. Here, the size and shape of the distal end 258 are substantially the same as the top channel 38 to form a substantially permanent snap fit or friction fit. Similarly, the tooth member 10 of the first embodiment can be attached to the distal end 258 of the base member. Alternatively, the tooth members 10, 30 can be attached to the ends 258, 260, 262 of the head member 250 by other methods (such as adhesives, fasteners and welding).

[0089] like Figures 10 to 12As shown, preferably, head member 250 is configured so that head member distal end 258 is positioned closer to the user, and head member proximal end 260 comprises tooth member 10,30 and is positioned away from the user. In use, tooth member 10,30 engages with the cleaning surface and the user pulls head member 250 toward the user.

[0090] Reference Figures 18 to 26 , shows an alternative embodiment of the head member 250. The overall structure of the head member 250 is substantially similar to Fig.11 Therefore, each common component of the head member 250 is Figures 18 to 26 However, in this embodiment, the head member 250 includes tooth members 10a, 10b, which are slightly modified from those described above and in Figure 1 Specifically, the extensions or protrusions 18 of the tooth members 10a, 10b have sharper edges and have a height that is smaller than the height of the tooth member 10. In this embodiment, as shown in FIG. Fig.25 As shown, the transverse proximal end 260 of the head member 250 includes a tooth member 10a having a channel 22 aligned therewith. That is, the pair of extensions 18 extend substantially parallel thereto from the transverse proximal end 260. Similarly, as Fig.26 As shown, the transverse distal end 258 of the head member 250 includes a tooth member 10b having a channel 22 aligned therewith. That is, the pair of extensions 18 extend substantially parallel thereto from the transverse distal end 258. Although the tooth members 10a, 10b are similar in geometry, the diameter of the rear tooth member 10b is smaller and the flange 16 is closer together, that is, the groove 14 is narrower. The rear tooth member 10b has smaller teeth, which are sharper and more aggressive on the cleaning surface. In this way, the rear tooth member 10b is more suitable for deeper cleaning on harder fabrics. The front tooth member 10a is softer than the rear tooth member 10b and is more suitable for cleaning more fluffy or softer surfaces.

[0091] Still refer to Figures 18 to 26 , with this configuration, the user has two separate options on a single device. That is, in use, when cleaning harder surfaces, the user utilizes the rear tooth member 10b by engaging the end of the flange extension 18 with the cleaning surface and pulling the handle 256 toward the user to collect debris. When cleaning softer surfaces, the user utilizes the front tooth member 10a by engaging the end of the flange extension 18 with the cleaning surface and pulling the handle 256 toward the user to collect debris.

[0092] The head member 250 is constructed of plastic and is integrally formed via injection molding. However, other materials, such as metals and composite materials, may be used, and the base member 252, support member 254 and extension member 256 may also be manufactured separately and attached together by various methods, such as welding, adhesives or fasteners.

[0093] exist Figures 10 to 12 In the illustrated embodiment, the extension member 256 is tubular for receiving an extendable handle member 268. The extension member 256 includes opposing and aligned holes 270 for securing the handle member 268 to the extension member 256 via known methods, such as with fasteners 272 or spring-loaded pins. The handle member 268 includes a pair of telescoping tubes 274, 276 that are locked and unlocked with a threaded locking mechanism 278. The handle member 268 is constructed of metal for its durability, but other materials such as plastics and composites may be used.

[0094] Alternatively, the handle member 268 can be constructed as more than two tubes and coupled together with internal threads and further secured to each other with fasteners extending through a plurality of holes machined through adjacent tubes. In this way, the handle member is further strengthened so that the handle member can withstand forces during use. Although in Figures 18 to 26 Although not specifically shown in the drawings, the head member 250 in this embodiment may also be constructed with similar extension members 256 and handle members as described above.

[0095] In an alternative embodiment, the extension member 256 may be formed as or include a handle, or simply function as a handle, so that the cleaning device may be used without the extension handle member 268. This may be particularly useful for cleaning in smaller spaces, such as the interior of an automobile, where the use of an extended handle is not feasible due to limited space.

[0096] refer to Figures 13 to 17, shows a second embodiment of the head member 280 of the present invention. The head member 280 extends longitudinally and includes a curved base member 282 having an upwardly extending distal end 284 and a laterally extending opposite substantially flat proximal end 285. The head member 280 is integrally formed with a support member 286, which extends laterally from a proximal end 287 to a distal free end 288 opposite the base member distal end 284. The support member distal end 288 includes a downwardly extending engagement member 290 that extends longitudinally along the support member 286. The engagement member 290 is sized and shaped to receive the top channel 20, 38 of the tooth member 10, 30 via a snap fit or form fit. Alternatively, the tooth member 10, 30 can be attached to the engagement member 290 by other methods such as adhesives, fasteners, and welding. The shell member 292 is integrally formed on the base member 282 between the distal end 285 and the proximal end 287 of the base member. The shell member 292 includes opposing shell holes 294 for receiving a plastic rotating shaft 296, which is rotatably coupled therein. In the alternative, the rotating shaft 296 can be constructed of other materials, including metal. The extension member 298 is fixedly coupled to the rotating shaft 296 so that the extension member 298 can pivot about the shaft 296 based on the rotation of the shaft 296. The shell member 292 includes a locking mechanism (not shown) for limiting the rotation of the shaft 296. The extension member 298 includes a lower member 300 extending upward from the shaft 296 and a tubular receiving member 302 integrally formed and extending upward from the lower member 300. The receiving member 302 includes opposing and aligned holes 304 for being engaged and disengaged via known methods (such as using fasteners 272, such as Fig.16 and Fig.17 ) or a spring loaded pin to secure the handle member 268.

[0097] Reference Fig.14 and Fig.15 As shown by the arrow, the extension member 298 is configured to extend from Fig.14 Preferably, the shaft 296 is configured so that the extension member 298 can be rotated to a position parallel to the base member 282 away from the tooth component 10, to a position 30 degrees from the vertical or upright position toward the tooth component 10. However, those skilled in the art will recognize that the rotatable position can be adjusted without departing from the spirit and scope of the present invention.

[0098] like Figures 13 to 17As shown, preferably, the head member 280 is configured so that the tooth member 10 is positioned away from the user. In use, the tooth member 10 engages with the cleaning surface and the user pulls the head member 280 toward the user. This embodiment is particularly advantageous because the user does not need to adjust the angle of attack because the flange extension or lip 18 of the tooth member 10 will always be perpendicular to the cleaning surface due to the pivoting extension member 298.

[0099] The base member 282, the support member 286 and the housing member 292 are constructed of plastic and are integrally formed via injection molding. Similarly, the rotational shaft 296 and the extension member 298 are constructed of plastic and are formed separately via injection molding. However, other materials, such as metals and composite materials, may be used, and the components of the head member 280 may also be manufactured separately and attached together by various methods (e.g., welding, adhesives, or fasteners).

[0100] Reference Figures 13 to 16 Optionally, the head member 280 is provided with a reinforcement hole 306 extending longitudinally along the length of the head member 280. A metal rod (not shown) may be inserted into the reinforcement hole 306 for further stability and to prevent deformation of the head member 280.

[0101] The above advantages and those that are apparent from the above description can all be effectively achieved. Because certain changes can be made to the above construction without departing from the scope of the invention, it is intended that all content contained in the foregoing description or shown in the accompanying drawings should be interpreted as illustrative rather than restrictive.
