Description

Technical field of the invention

The invention relates to a brush for a motor vehicle.

It relates to the technical field of brushes which can be fitted on a motor vehicle in order to ensure the cleaning or treatment of large surfaces. The invention relates more particularly, but not exclusively, to brushes which could be called "static", i.e. the bristles of which are not driven by any own movement other than that derived from their contact with the surface to be brushed during the displacement of the vehicle .

Prior art

Document US 2003/177596 (STEWART) describes a brush for a motor vehicle, the body of which comprises on a lower face a set of horizontal and longitudinal rows of rubber scrapers which extend in a direction substantially normal to the lower face. This set of scrapers is combined with lateral brushes in the form of triangles which are configured to sweep the corners situated between a vertical wall and a horizontal floor. These lateral brushes are straight, parallel to the longitudinal axis of the body, and situated at the same level as the scrapers.

Document EP 0.103.471 (TENNANT) describes a "dynamic" brush where lateral deflectors make it possible to gather waste towards rotary brushes. These deflectors are situated at the front of the brush, in front of the rotary brushes.

Document WO 2010/052384 (SANEF) describes a device for gathering objects where lateral deflectors make it possible to gather waste towards a gathering plate. These deflectors are situated at the front of the brush, in front of the plate.

There is known more particularly from patent document EP 2.269.484 (ACTIWORK) a brush for a motor vehicle comprising an elongate body which is equipped with means for fitting on the vehicle, and which comprises on a lower face a set of longitudinal rows of bristles which extend in a direction substantially normal to the lower face. The rows of this set are parallel to one another, and each have, seen from the lower face of the body, a shape which is curved or in the form of a "C" or a "V" . A set of rows of this type which is thus curved or in the form of a "C" or a "V" makes it possible to obtain a sweeping quality which is far better than that obtained with a brush which comprises only straight rows of bristles. In fact, when the concavity of the rows of this set is oriented towards the front of the body of the brush, the said set forms a collecting region which makes it possible to concentrate a larger quantity of sweepings. Thus, the occurrence of deposit lines or accumulations of waste or dust along the trajectory of displacement of the brush is reduced, or occurs after a displacement distance which is far greater than in the case of use of a brush comprising only straight rows of bristles.

This brush is satisfactory as a whole. However, it has been found that in certain conditions of use, the brushing carried out is not completely satisfactory. In particular, it is generally very difficult to gather the sweepings (e.g. dust or waste) which have accumulated against walls or other vertical obstacles (e.g. posts or pillars), since the body of the brush forms an obstacle and prevents the bristles from reaching these parts. In addition, when the surface to be swept is relatively large, the collecting region can be saturated, and lead to discarding of some of the sweepings recuperated at the edges of the region of passage of the brush.

In view of this situation, the objective of the invention is to improve the quality of the sweeping of a brush which can be fitted on a motor vehicle, and more particularly, but not exclusively, the sweeping of a brush of the type described in the aforementioned patent document EP 2.269.484.

The objective of the invention is also to increase the capacity for recuperation of the sweepings.

The objective of the invention is also to improve the recuperation of the sweepings at walls or other vertical obstacles .

Disclosure of the invention

The solution proposed by the invention is a brush for a motor vehicle, the said brush comprising an elongate body which is equipped with means for fitting on the vehicle, and comprises on a lower face a first set of longitudinal rows of bristles extending in a direction which is substantially normal to the lower face. The rows of this first set each have, seen from the lower face of the body, a shape which is curved or in the form of a "C" or a "V". This brush is distinguished in that: the elongate body additionally comprises on the said lower face at least a second set of longitudinal rows of bristles extending in a direction substantially normal to the lower face, the said second set being arranged behind the said first set, and offset from the latter such as to define a collecting region for the sweepings; the said second set is paired with deflectors which are oriented towards the front of the body, such as to gather towards the collecting region the sweepings obtained from the first set, or which have escaped from the region of passage of the said first set; and seen from the lower face of the body, the said deflectors extend from the lateral edges of the said body.

As a result of their configuration, the deflectors increase the capacity for storage of the sweepings at the set of rows of bristles, with the assembly forming a consistent collecting region. They also make it possible to gather easily the sweepings which have accumulated at the walls or vertical obstacles, towards the second set. In addition, the presence of an additional collecting region increases the capacity for recuperation of the sweepings. This collecting region is delimited longitudinally by the first, front set of bristles and the second, rear set of bristles (and more particularly by the offsetting between these two sets) , and is delimited laterally by the deflectors. In addition, the deflectors have a triple function: firstly they make it possible to gather the sweepings initially recuperated by the first set, and which have escaped from the edges of the region of passage of the brush because of the saturation of the said first set; they also make it possible to return easily the sweepings which have accumulated at walls or vertical obstacles, towards the new collecting region; finally, they make it possible to increase the volume of the new collecting region, since they to limit this region laterally.

Other characteristics of the brush which is the subject of the invention are listed hereinafter, each of these characteristics being able to be considered alone or in combination, independently of the distinguishing characteristics previously defined: the rows of the second set can each have, seen from the front face of the body, a shape which is curved or in the form of a "C" or a "V", and the concavity of which is oriented towards the front of the body, such as to define the collecting region for the sweepings. According to a variant embodiment, the rows of the second set are straight and parallel to a longitudinal axis of the body; the deflectors are advantageously situated at each of the lateral ends of the row of the second set which is closest to the rows of the first set; when the brush is seen from the front, the deflectors advantageously extend from the lateral ends of the rows of the first set; seen from the lower face of the body, the deflectors preferably extend from the lateral edges of the said body; the deflectors are advantageously in the form of bristles, which are preferably all attached to the body of the brush; according to a variant embodiment, the deflectors can be in the form of solid blades or lamellae; the deflectors can be oriented in a direction substantially normal to the lower face of the said body; the rows of the first set preferably have concavity which is oriented towards the front of the body, such as to define a collecting region for the sweepings; the rows of the first set and the rows of the second set do not necessarily have the same concavity; according to a variant embodiment, the rows of the first set have concavity which is oriented towards the rear of the body; according to a preferred embodiment, on the lower face, the body additionally comprises a third set of longitudinal rows of bristles extending in a direction substantially normal to the lower face, the rows of the said third set being curved or straight, and parallel to a longitudinal axis of the said body, the said third set being arranged behind the said second set; this third set can be paired with deflectors, which are situated at each of the lateral ends of the row of the said third set which is closest to the rows of the second set; on its lower face, the body can additionally comprise another set of longitudinal rows of bristles extending in a direction substantially normal to the said lower face, the rows of the said other set each having, seen from the lower face of the body, a shape which is curved or in the form of a "C" or a "V", and the concavity of which is oriented towards the front of the said body, such as to define another collecting region for the sweepings, the said other set being arranged behind the said second set. This other set is also paired with deflectors which are configured to gather the sweepings obtained from the second set, or which escape from its area of passage, towards the other collecting region.

Description of the figures

Other advantages and characteristics of the invention will become more apparent from reading the description of a preferred embodiment which will follow, with reference to the accompanying drawings, provided by way of indicative and nonlimiting examples, and in which: figure 1 is a schematic perspective in three-quarter view from the lower face of the body of the brush which is the subject of the invention; figure 2 is a schematic view from below of the brush in figure 1; figure 3 is a schematic front view of the brush in figures 1 and 2; figures 4 to 8 are schematic views from below of other embodiments of the brush which is the subject of the invention; figures 9 and 10 are schematic views from below of other embodiments of a brush for a motor vehicle.

Embodiments of the invention A brush B which is the subject of the invention is designed to be fitted on a motor vehicle, for example a forklift truck. Thus, with reference to figure 3, and as described in the aforementioned patent document EP 2.269.484, the brush B comprises an elongate body 1 which is equipped with means 2 for fitting on the vehicle. The means 2 can be produced in any appropriate manner according to the nature of the vehicle. Within the context of the example illustrated, the means 2 are designed to permit fitting of the brush B on the forks of a forklift truck, and comprise two sleeves which are arranged on the upper surface of the body 1. Blocking means, of the pin type, make it possible to block the movement of the brush B relative to the forks of the truck.

In order to ensure its sweeping function, on the lower face of the body 1, the brush B comprises rows 10, the bristles of which extend according to a direction substantially normal to the lower face of the body 1 (figure 1).

The rows 10 of bristles are preferably distributed in at least two sets of rows SI and S2. Preferably, a third row S3 with a different configuration is provided. In figures 9 and 10, the rows of bristles 110 are however distributed on a single set SO .

According to the preferred embodiment illustrated in figures 1 to 7, a first set SI is formed of longitudinal rows 101 of bristles extending in a direction substantially normal to the lower face of the body 1. The rows 101 of this first set SI are advantageously parallel to one another, and extend substantially over the entire length of the body 1, such as to reach, or at least be very close to, its lateral edges 11. In the accompanying figures, the first set SI comprises two rows 101, but a larger or smaller number of rows can be provided. The rows 101 are spaced from one another (accompanying figures) or on the contrary they are attached to one another.

The rows 101 of the first set SI advantageously each have, seen from the lower face of the body 1, a form which is curved (for example an arched form, without a break, a form of a portion of elliptical curve, etc.), or the form of a "C" or a "V". In the accompanying figures, the rows 101 all have a form in the shape of a "V" or a chevron, and are parallel to one another. The two branches of the "V" are preferably straight, but a configuration in which the branches are not straight (for example curved or in the form of a zigzag) can be envisaged. In addition, the rows 101 are all arranged such as to be generally symmetrical relative to a median transverse plane, known as the sagittal plane S, which passes via the tip of each of the said rows. An asymmetrical configuration of the rows 101 relative to the plane S can be envisaged.

According to the example illustrated in figures 1, 2, 4, 5 and 7, the rows 101 which constitute the first set SI are arranged such that their concavity is oriented towards the front of the body 1, or their tip faces towards the rear of the said body. The front and the rear of the body 1 are defined relative to the direction and normal sense of advance D of the vehicle which is displacing the brush B. With reference more particularly to figure 2, this configuration of the rows 101, the concavity of which is oriented towards the front, forms a first recuperation region Z1 where the sweepings 30 are received and retained when the operator commands the advance of the vehicle, and the brush B pushes in front of it the said sweepings (waste, dust, etc.) which are present on the surface 3 to be cleaned. The inclination of the rows 101 and the depth of the set SI define in particular the capacity for storage of the sweepings 3. Thus, the first set SI prevents rapid occurrence of lines of accumulation of sweepings 30 at the lateral edges 11 of the brush B.

In the variant embodiment in figure 8. It is envisaged to eliminate the concavity of the first set SI. More particularly, the rows 101 of the first set SI have a straight form, seen from the lower face of the body 1. The rows 101 can be parallel or non-parallel to the longitudinal axis L of the body 1.

In the variant embodiment in figure 6, it can be envisaged to orient the concavity of the first set SI towards the rear of the body 1, or for the tip of the rows 101 to face towards the front of the said body. This configuration makes it possible to discard the sweepings at the sides 11 of the brush B, which can be useful in certain applications, in particular in order for them to be recuperated by the second set S2 which will now be described in greater detail.

According to the invention, the body 1 additionally comprises on its lower face at least a second set S2 of longitudinal rows 102 of bristles. The latter extend in a direction which is substantially normal to the lower face of the body 1. The second set S2 is arranged behind the first set SI, and offset from the latter such as to define a collecting region Z2 for the sweepings 30. The rows 102 are spaced from one another (accompanying figures), or on the contrary they are attached to one another.

The rows 102 of the second set S2 are advantageously parallel to one another, and, as for the first set SI, extend substantially over the entire length of the body 1, such as to reach, or at least be very close to, the lateral edges 11. In the accompanying figures, the second set S2 comprises two rows 102, but a larger or smaller number of rows can be provided.

In figures 1 to 7, the rows 102 of the second set S2 each have, seen from the lower face of the body 1, a form which is curved (for example an arched form, without a break, a form of a portion of elliptical curve, etc.) or a form of a "C" or a "V". In figures 1 to 5, the rows 102 of the second set S2 have the same form, and are parallel to the rows 101 of the first set SI. The sets SI and S2 can however have different concavities, with the rows 101 and 102 not necessarily having the same form, and/or not necessarily being parallel.

In figures 1 to 7, the rows 102 all have a form in the shape of a "V" or a chevron, and are parallel to one another. The two branches of the "V" are preferably straight, but a configuration in which the branches are not straight (for example curved or in the form of a zigzag) can be envisaged. In addition, the rows 102 are all arranged such as to be generally symmetrical relative to the plane S. An asymmetrical configuration of the rows 102 relative to the plane S can however be envisaged.

The rows 102 which constitute the second set S2 are arranged such that their concavity is oriented towards the front of the body 1, or their tip is facing towards the rear of the said body. This configuration makes it possible to form a second recuperation region Z2 where the sweepings 30 can be received and retained. The inclination of the rows 102 and the depth of the set S2 define in particular the capacity for storage of the sweepings 30 in the collecting region Z2. In the case when the rows 101 and 102 which constitute respectively the first set SI and the second set S2 have their concavity oriented towards the front of the body 1, the brush B provides two collecting regions Z1 and Z2. The capacity for storage of the sweepings 30 is thus doubled in comparison with that of the

brush described in the aforementioned patent document EP 2.269.484. In the example in figure 6 in which the two sets SI and S2 have opposite concavities, it is found that the recuperation region Z2 has a storage capacity which is distinctly increased.

In the variant embodiment in figure 8, the rows 102 of the second set S2 are straight and parallel to the longitudinal axis L of the body 1. The second set S2 is arranged behind the first set SI, and offset from the latter such as to define a recuperation region Z2. In this particular configuration of the second set S2, the rows 101 of the first set SI can be straight (figure 8) or can have a shape which is curved or in the form of a "C" or a "V" (as in figures 1, 2, 4, 5, 6 and 7) .

With reference to the example illustrated in the accompanying figures 1 to 8, the second set S2, whether it has a straight or curved form, is paired with deflectors 120 which are oriented towards the front of the body 1, such as to gather the sweepings 30 obtained from the first set SI, or which have escaped from the region of passage of the said first set, towards the second collecting region Z2. In practice, the deflectors 120 are situated at each of the lateral ends of the row 102 of the second set S2 which is closest to the rows 101 of the first set Si. By this means, the sweepings 30 are driven directly into the collecting region Z2, and not inside the rows 102.

The new collecting region Z2 has a volume which can be consistent in that, as shown in the accompanying figures, it is delimited longitudinally by the first row 102 (which is the one closest to the front edge of the body 1) of the second set S2, and by the last row 101 (which is the one closest to the rear edge of the body 1) of the first set SI. The collecting region Z2 is also delimited laterally by the deflectors 120. The volume of the collecting region Z2 can be adjusted by regulating the distance which separates the two sets SI and S2, and/or by regulating the dimensions of the deflectors 120.

With reference to figure 3, when the brush B is seen from the front, the deflectors 120 extend by a distance "d" from the lateral ends 1010 of the rows 101 of the first set SI. In practice, the distance "d" is between 5 cm and 50 cm. Thus, when the sweepings 30 exit from the first storage region Zl, or are discarded to the sides 11 of the brush B (figure 6) , the said sweepings are trapped directly by the deflectors 120, and directed to the second storage region Z2. The same applies to the sweepings which escape from the region of passage of the first set SI.

With reference to figure 2, seen from the lower face of the body 1, the deflectors 120 also extend from the lateral edges 11 of the said body. By this means, the deflectors 120 can efficiently gather the sweepings which have accumulated at walls M or vertical obstacles, towards the storage area Z2, without any risk of the body 1 scraping the said walls or the said obstacles.

The deflectors 120 are advantageously in the form of bristles, although they can be in the form of solid blades or lamellae, for example made of flexible or rigid plastic material. In practice, the bristles are all attached to the body 1, and more particularly to the lateral edges 11 of the body 1, between the first row 102 of the second set S2 and the last row 101 of the first set SI. As shown clearly in figure 1, the deflectors 120 thus have curvature which improves the guiding of the sweepings 30 towards the second storage region Z2, whilst preventing them from exiting from the said region. Very good results are however obtained with deflectors 120 which are straight, and/or do not have any curvature.

The deflectors 120 can also be fitted in a manner which is detachable or not detachable on the body 1, and they can be oriented according to a direction which is substantially normal to the lower face of the said body. For this purpose, each of the deflectors 120 can for example be fitted on a hinge, the axis of which is substantially normal to the lower face of the body 1, or on catches or a pin, thus making it possible to block the said deflectors in the required position. It is thus possible to regulate the angle of opening "a" of the deflectors 120, and incidentally their amplitude. The region of capture of the deflectors 120 can thus be modulated by the operator according to the configuration of the locations to be cleaned.

According to a preferred embodiment schematised in figures 1 and 2, the body 1 comprises on its lower face a third set S3 of longitudinal rows 103 of bristles extending in a direction substantially normal to the said lower face. The third set S3 is arranged behind the second set S2, and more generally at the rear of the body 1. The rows 103 are parallel to one another and straight, and parallel to a longitudinal axis L of the body 1. The rows 103 can however be curved. According to the example illustrated, the set S3 comprises four rows 103 of bristles, on the understanding that the bristles can comprise fewer rows, for example only two rows, or on the contrary more rows. The rows 103 are spaced from one another or on the contrary are attached to one another. The best results are obtained when this third set S3 is present on the brush B. However, this third set S3 is not essential in order to obtain efficient sweeping, and a brush B without this set can be envisaged as illustrated in figures 4 to 6.

In addition, as shown in figures 2, 7 and 8, the third set S3 can optionally be paired with deflectors 130. The latter make it possible in particular to recuperate the smallest sweepings which would have escaped or would have passed through the deflectors 120. The deflectors 130 are advantageously situated at each of the lateral ends of the row 103 of the third set S3 which is closest to the rows 102 of the second set S2.

According to the example illustrated in figures 1 to 4 and 8, the brush B additionally comprises at least one, and according to the example, two auxiliary lines 15 of bristles extending in a direction substantially normal to the lower face of the body 1. Each ine 15 advantageously has a straight form, parallel to the longitudinal axis L, and has a length which is smaller than the length of the body 1. The lines 15 are advantageously arranged in the concavity of the first row 101 of the first set SI, and are substantially centred relative to the latter and to the sagittal plane S, whilst being parallel to one another. The lines 15 prevent excessive accumulation of the sweepings in the tip of the "V" formed by the rows 101 of the first set S2. These lines 15 also absorb the dust of the swept materials which gradually accumulates in the concavity, thus preventing the bristles of the first set SI from curving too far rearwards, and thus allowing some of the sweepings to pass. However, very satisfactory results are obtained even when the brush B is without lines 15.

In the variant embodiment in figure 7, the body 1 comprises on its lower face another set S2' of longitudinal rows 102' of bristles. This set S2' has a form similar to the second set S2, its rows 102' each having, seen from the lower face of the body 1, a form which is curved (for example an arched form, without a break, a form of a portion of elliptical curve, etc.), or the form of a "C" or a "V, their concavity being oriented towards the front of the said body, such as to form another recuperation region Z2'. The other set S2' is arranged behind the second set S2, and optionally in front of the third set S3, if the latter is provided. In this configuration, the rows of the sets S2 and S2' do not have the same length, the rows 102 being shorter than the rows 102'. In the example illustrated, the length of the rows 102 of the second set S2 is shorter than the length of the body 1, and these rows do not reach the lateral edges 11. On the contrary, the rows 102' of the other set S2' extend substantially along the entire length of the body 1, such as to reach, or at least be very close to, the lateral edges 11.

It should be noted that the rows 102' of the other set S2' can be straight and parallel to the longitudinal axis L of the body 1, in a manner similar to the rows 102 schematised in figure 8. By being offset from the second set S2, the other set S2' defines another recuperation region.

Like the second set S2, the other set S2' is paired with deflectors 120' which are configured to gather the sweepings obtained from the said second set S2, or which escape from its region of passage, towards the other collecting region Z2'. The deflectors 120' are similar to the deflectors 120 previously described. In practice, the deflectors 120' are situated at each of the lateral ends of the row 102' of the other set S2' which is closest to the rows 102 of the second set S2' .

When the brush B is seen from the front, the deflectors 120' extend from the lateral ends of the deflectors 120 which are paired with the second set S2, by a distance of between 5 cm and 50 cm. Thus, when the sweepings exit from the second storage region Z2, or are discarded at the sides 11 of the brush B, the said sweepings are trapped directly by the deflectors 120', and directed towards the other storage region Z2' . The same applies to the sweepings which escape from the region of passage of the sets SI and S2.

Seen from the lower face of the body 1, the deflectors 120' also extend from the lateral edges 11 of the said body, whereas the deflectors 120 do not necessarily extend from them. It is thus now the deflectors 120' which can efficiently gather the sweepings which have accumulated at walls or vertical obstacles, towards the storage region Z2', without any risk of the body 1 scraping the said walls or the said obstacles .

According to the example in figure 7, the brush B thus now provides three collecting regions Zl, Z2 and Z2', the capacity for storage of the sweepings being reduced relative to that of the brush described in the aforementioned patent document EP 2.269.484. It will be understood that other sets can thus be arranged behind one another such as to increase the number of collecting regions.

The bristles of each of the rows 10, 101, 102, 102', 103 and of the lines 15 preferably all have substantially the same length, but do not necessarily have the same diameter, as explained in the patent document EP 2.269.484 to which persons skilled in the art can refer. Each line or row of bristles is constituted by a segment of a strip of bristles, an end of which is retained by a longitudinal head made of plastic material or the like, which is designed to be engaged in a groove in the form of a "C". An embodiment of this type of the row or line permits replacement of the rows or lines of bristles independently from one another. An embodiment of this type of the rows of bristles is described in particular within the context of patent US 5 621 940, and therefore does not need to be described in further detail.

The brush B according to the invention thus constituted is implemented as follows. Firstly, the brush is fitted on the forks of the motor vehicle, such that the concavity of the second set S2 is oriented towards the front of the body 1 in the direction of normal travel D of the vehicle. Fitting means 2 are provided for this purpose. It will be appreciated that another orientation of the second set S2 can be envisaged, for example towards the rear, and the means for adaptation 2 can then be designed to be removable, such as to permit a change of their relative orientation. Once this fitting has been carried out, a driver of the vehicle regulates the height of the forks, such as to apply the bristles against the surface 3 to be brushed or cleaned. It should be noted that, since all the bristles have substantially the same height, they are all supported on the surface to be cleaned if the latter is flat. This height can be selected to be approximately 10 to 35 cm for example, and preferably approximately 30 cm for autonomy (wear) of several hundred kilometres on tarred surfacing. The driver of the vehicle can also regulate the forks such as to exert slight pressure on the brushes, in order to bend them very slightly and thus allow them to adapt well to the slight irregularities of the surface to be swept. Then, the operator commands the advance of the vehicle, such that the brush B pushes in front of it the sweepings 30 present on the surface 3 to be cleaned. The presence of the sets SI, S2 (and optionally S2')/ the concavity of which is oriented forwards, thus makes it possible to receive a large quantity of sweepings 30 in the different collecting regions Zl, Z2 (and optionally Z2') . It has been found that the brush B according to the invention makes it possible to obtain a sweeping quality which is distinctly better than that obtained with a brush of the type described in patent document EP 2.269.484.

Figures 9 and 10 illustrate a configuration in which a brush B, which does not come within the scope of the brush presently claimed, comprises a set SO of longitudinal rows 100 of bristles extending in a direction substantially normal to the lower face. The brush B can comprise other sets of rows, for example of the type previously described. The rows 100 each have, seen from the lower face of the body 1, a straight form (figure 10) or a form which is curved or in the shape of a "C" or a "V" (figure 9). This set SO is paired with deflectors 120 which are oriented towards the front of the body 1. These deflectors 120 are similar to those previously described. Seen from the lower face of the body 1, the deflectors 120 extend from the lateral edges 11 of the said body. In this configuration, they can efficiently gather the sweepings which have accumulated at walls M or vertical obstacles towards the set SO, without any risk of the body 1 scraping the said walls or the said obstacles. In addition, the deflectors 120 increase the capacity for storage of the sweepings of the set SO, with the rows 110 and the said deflectors defining a consistent collecting region Z.

It will be appreciated that various other modifications can be made to the invention within the context of the accompanying claims .
