Description

CARPET CLEANING DEVICE
This invention relates to a device suitable for cleaning carpets having a pile, the device having a brush which is optionally replaceable, and to the replaceable brushes themselves.
The problem of cleaning carpets is well-known. Many devices have been devised which seek to provide improved carpet cleaning, one of the most successful of which has been the vacuum cleaner. However, a difficulty with these prior art devices is that debris such as human hair, pet hair and other foreign bodies more securely embedded into the pile of the carpet are difficult to remove.
A way of ameliorating these problems has been sought.
According to the present invention there is provided a device suitable for cleaning carpets having a pile, the device having a brush head comprising a brush which has bristles which in use penetrate the pile of the carpet to remove debris.
Advantages of the present invention include that human hair, pet hair and other foreign bodies may be more effectively removed from a carpet than
has been possible with prior art devices.
It is preferred that the brush head comprises a replaceable brush receptacle and a replaceable brush. Preferably the replaceable brush receptacle and the replaceable brush are connected by coupling means.
More preferably the coupling means comprise a receiving portion and a projecting portion. Most preferably the receiving portion is a groove and the projecting portion is a tongue.
It is preferred that the coupling means comprise an interference fit, i.e. the fastening between the two parts is achieved by friction after the parts are pushed together. Such a fitting is a'so known as a press fit. The coupling means may comprise a lock. The lock may be in the form of a bead and a notch or in the form of one or more hinged panels which close to prevent the replaceable brush from being removed from the replaceable brush receptacle.
It is preferred that the bristles have a pile such that they abrasively contacts a carpet surface when moved across the carpet surface in a first direction relative to the pile of the bristles and non-abrasively contact the carpet surface when moved across the carpet surface in a second direction relative to the pile of the bristles.
The material VelcroTM normally comprises a surface covered in hooks and a surface covered in loops. It is preferred that at least some of the bristles have hooked ends, for example such as those used for the hooked surface of VelcroTM. The hooked end of such bristles are particularly useful in lifting embedded debris from the pile of a carpet. Preferably the bristles form a fish scale pattern.
It is preferred that the cleaning device comprises an elongate handle connected to the brush head. The handle may be connected to the brush head by a fixed joint, e.g. one that is screwed on, or by a rotatable joint.
Preferably, the rotatable joint is a ball and socket joint.
The brush may be used wet or dry.
The present invention will be further described in greater detail by reference to the following Figures of the accompanying drawings which are not intended to limit the scope of the invention claimed, in which: Figure 1 shows an overview of a carpet cleaning device according to one embodiment of the invention; Figure 2 shows a coupling portion of a replaceable brush head and a receiving portion of a brush head receptacle according to one embodiment of the invention; and Figure 3 shows a side view of part of the replaceable brush head and the receiving portion of the brush head receptacle of Figure 2 when connected.
Figure 4 shows a coupling portion of a replaceable brush head and a receiving portion of a brush head receptacle according to an alternative embodiment of the invention.
Figure 5 shows a side view of part of the replaceable brush head and the receiving portion of the brush head receptacle of Figure 4 when connected.
Figure 6 shows an embodiment of the invention where a ball and socket joint connects the brush head to the elongate handle.
Figure 7 shows a carpet being cleaned by a brush according to an embodiment of the invention where the bristles have hooked ends.
Figure 1 shows a device (5) suitable for cleaning carpets having a pile.
The device (5) has an elongate handle (10), a brush head (15) and a brush (20) formed of bristles. In this embodiment, and those shown in Figures 2 to 5, the elongate handle is connected to the brush head by a fixed joint.
Figures 2 and 3 depict an embodiment of the invention having a replaceable brush. The close-up views of brush head (15) show how the replaceable brush (30) is replaced. The brush head (15) comprises a replaceable brush receptacle (25) and a replaceable brush (30). Figure 2 shows the replaceable brush head (30) removed from the replaceable brush receptacle (25) in order to show the coupling means (26) by which these two parts of the brush head (15) are connected. Replaceable brush (30) comprises bristles (20) on its lower surface and coupling means (35A) and (35B) running along its length. In this embodiment the coupling means (35A) and (35B) on the replaceable brush (30) are projecting portions in the form of tongues. Replaceable brush receptacle (25) comprises internal recess (40) and coupling means (45A) and (45B) that run along the length of the internal recess (40). In this embodiment the coupling means (45A) and (45B) are receiving portions in the form of grooves. When connecting the replaceable brush (30) to the replaceable brush receptacle (25), the tongues (35A) and (35B) slidably cooperate with the grooves (45A) and (45B).
Once the replaceable brush (30) is fully inserted into the replaceable brush receptacle (25) it is secured in position by the closing of hinged panels (46). These hinged panels (46) are shown in Figure 2 the open position prior to the insertion of the replaceable brush (30). When closed, projections (47A, 47B) engage depressions (48A, 48B) in order to retain the panel in the close position. Such hinged panels (46) are an optional feature and may be retained in the closed position in a variety of ways known in the art. Alternatively, they may be replaced by a notch and bead system such as that shown in Figure 5. Another alternative for securing the replaceable brush (30) in the brush receptacle (25) is that the replaceable brush (30) is formed from a resilient material such as rubber and has a width which is slightly greater than the width of the replaceable brush receptacle (25) such that there is a tight fit between the replaceable brush (30) and the replaceable brush receptacle (25). This tight fit is referred to herein as an interference fitting Figure 3 shows a close-up side view of the joint formed once the replaceable brush (30) and replaceable brush receptacle (25) of Figure 2 have been fitted together. Tongues (35A, 35B) engage grooves (45A, 45B) and the replaceable brush (30) is retained in this position in the replaceable brush receptacle (25) due to the tongues (35A, 35B) and the grooves (45A, 45B) forming an interference fitting as described above.
The replaceable brush (30) may additionally be secured by hinged panels (46), also as discussed above.
Figures 4 and 5 show close-up views of the brush head (15) according to an alternative embodiment of the invention having a replaceable brush head. The brush head (15) comprises a replaceable brush receptacle (25) and a replaceable brush (30). Figure 4 shows the replaceable brush (30) removed from the replaceable brush receptacle (25) in order to show the coupling means (26) by which these two parts of the brush head (15) are connected. Replaceable brush (30) has bristles (20). In this embodiment the coupling means are different to those shown in Figures 2 and 3. The projecting portions (35A) and (35B) in the form of tongues on the replaceable brush (30) shown in Figures 2 and 3 are substituted with receiving portions (50A) and (50B) in the form of grooves running along its length. In addition, the receiving portions (45A) and (45B) in the form of grooves on the replaceable brush receptacle (25) shown in Figures 2 and 3 are substituted with projecting portions (55A) and (55B) in the form of tongues running along the length of the internal recess (40). When connecting the replaceable brush (30) to the replaceable brush receptacle (25), the grooves (50A) and (50B) slidably cooperate with the tongues (55A) and (55B).
Figure 5 shows a close-up side view of the joint formed once the replaceable brush (30) and replaceable brush receptacle (25) of Figure 4 have been fitted together. Grooves (50A, 50B) engage tongues (55A, 55B) and the replaceable brush (30) is retained in this position in the replaceable brush receptacle (25) due to the grooves (50A, 50B) and the tongues (55A, 55B) forming an interference fitting as described above.
The replaceable brush (30) is additionally secured in position once it is fully inserted into the replaceable brush receptacle (25) by one or more beads (56) on the replaceable brush (30) that each engage a corresponding notch (57) on the replaceable brush receptacle (25). In an alternative configuration, the one or more beads (56) could be formed on the replaceable brush receptacle (25) and each corresponding notch (57) could be formed on the replaceable brush (30). A mixture of these two configurations is also possible. Such beads and notches are an optional feature, or they may be replaced by a hinged panel system such as that shown in Figure 2 or by an interference fitting.
Figure 6 shows an embodiment of the invention where a ball and socket joint is formed at the end of the elongate handle (10) that is connected to the top of the replaceable brush receptacle (25) of the brush head (15).
The ball and socket joint comprises ball (60) mounted on brush head (15) and socket (65) mounted on end of the elongate handle (10). An alternative arrangement would be to have the ball (60) mounted on end of the elongate handle (10) and the socket (65) mounted on the brush head (15). The rotational movement permitted by the movement of the ball (60) and the socket (65) relative to each other allows the elongate handle (10) to be placed at a variety of angles relative to the brush head (15).
The ball and socket joint means that when cleaning a carpet a user can manoeuvre the device (5) at difficult angles more easily using the elongate handle (10).
Figure 7 shows a close-up view of the brush (20) cleaning a pile (75) of a carpet (70). In this particular embodiment, the bristles (80) have hooked ends (85) in order to assist in the removal of debris during cleaning.
