GRIPPER FOR A HANDLE OF A SUCTION BRUSH

The present application relates to a gripper for a handle of a suction brush. After a machining step, it is necessary to clean certain parts using a suction brush to remove waste such as chips and / or cutting lubricant residues. For this, an operator grasps the handle of the suction brush with one of his hands and moves the brush, exerting an effort to press it onto the surface to be cleaned in order to promote the suction of the waste. In the case of a part comprising numerous reliefs, such as for example a stiffened isogrid type panel of a central box of blades, it is necessary to modify the orientation of the handle of the suction brush so that it is always well plated on the surface to be cleaned, which can be in a vertical position or in a horizontal position.

Conventionally, the handle of the brush is positioned between the fingers of the hand. According to this grip, it is very difficult to exert sufficient effort to correctly press the suction brush on the surface to be cleaned.

The present invention aims to remedy the drawbacks of the prior art.

To this end, the invention relates to a gripper for a handle of a suction brush, characterized in that it comprises a first part configured to be grasped by a hand as well as a second part which comprises at least a couple branches which form a tubular portion with a diameter substantially equal to or very slightly less than the diameter of the handle and which have free ends separated by a distance less than the diameter of the handle and determined so that after elastic deformation, the ends are separated by a distance greater than the diameter of the handle to allow the second part to be clipped onto the handle.

The gripper allows the operator to firmly hold the handle of the suction brush thanks to the ergonomic shape of the first part. The gripper allows an operator to be able to orient the handle differently from his hand, without having to modify the inclination of his wrist.

According to another characteristic, the tubular portion has a diameter very slightly less than the diameter of the handle.

According to a first embodiment, the gripper comprises an articulation connecting the first and second parts and which is configured to arrange the first and second parts relative to one another in at least two different positions.

According to another characteristic, the first part comprises a body of approximately spherical shape, with a diameter configured to allow an operator to position it in the hollow of one of his hands and to grip it with his fingers.

According to another characteristic, the joint comprises:

a yoke integral with one of the first and second parts, comprising two branches parallel to each other, an extension integral with the other of the first and second parts, configured to be inserted between the two branches, a cylinder configured to be housed in through holes provided in the two branches of the yoke and the extension in order to form a pivoting connection with a pivot axis, the extension and the yoke having shapes which cooperate and which are configured to hold the second part relative to the first part according to at least two different positions.

According to one configuration, the pivot axis is perpendicular to the axis of the tubular portion of the second part.

According to another configuration, each branch of the yoke comprises a first edge and a second edge parallel to the pivot axis, the distance between the first edge and the pivot axis being substantially equal to the distance between the second edge and the pivot axis and the articulation comprises a substantially planar contact face, positioned at the base of the extension, on either side of the extension and parallel to the pivot axis, the contact face being configured to cooperate alternately with the first edges or the second edges of the legs of the yoke, the contact face being separated from the pivot axis by a distance substantially equal to the distance between the first edge and the pivot axis.

According to another characteristic, the first edge and the second edge are connected by a junction edge parallel to the pivot axis and separated from the pivot axis by a distance greater than that separating the first edge and the axis of pivoting.

According to one configuration, for each branch, the second edge and the first edge form an angle between 110 ° and 150 °.

According to a second embodiment, the first and second parts are in one piece. According to one characteristic, the second part comprises a body, a first pair of branches and a second pair of branches, the first and second pairs of branches being offset in a direction parallel to the axis and connected by the body.

According to another characteristic, the first part comprises a handle and the body and the handle have a U-shape, the body forming a first branch of the U and the handle forming a base and a second branch of the U.

According to another characteristic, the base of the U is positioned in the extension of a first pair of branches and the second part comprises a boss positioned on the body on a face opposite to the second pair of branches, the boss having a palmar ergonomics, adapted in the palm of an operator's hand.

Other characteristics and advantages will emerge from the description of the invention which follows, description given by way of example only, with reference to the appended drawings in which:

FIG. 1A is a perspective view of a gripper which illustrates a first embodiment of the invention in a so-called horizontal position,

FIG. 1B is a perspective view of the gripper visible in FIG. 1A in a so-called vertical position,

FIG. 2 is a perspective view of the different parts of the gripper visible in FIG. IA in the disassembled state,

FIGS. 3 and 4 are perspective views of the gripper visible in FIG. 1A which illustrate different orientations of a handle,

FIG. 5 is a side view of a gripper which illustrates a second embodiment of the invention, and

FIG. 6 is a front view of the gripper visible in FIG. 6.

As illustrated in FIGS. 1A and 1B, a gripper 14 comprises a first part 16 configured to be gripped in a palm 18 of an operator (visible in FIGS. 3 and 4) and a second part 20 configured to be clipped onto a handle 10 (a section 12 of which is shown in dotted lines in the figures) of a tool such as a suction brush.

According to a first embodiment illustrated by Figures IA, IB, 2 to 4, a hinge 22 connects the first and second parts 16 and 20 and is configured to arrange the first and second parts 16, 20 relative to the other according to at least two different positions. The articulation 22 is also configured to maintain the second part 20 relative to the first part 16 in a first position, called the horizontal position (illustrated by FIGS. 1A and 3), or in a second position, called the vertical position (illustrated by Figures IB and 4).

The first part 16 comprises a body 24 which has palmar ergonomics, adapted to the palm of a hand 18 of the operator. The body 24 has a substantially spherical shape with a diameter allowing an operator to position it in the palm of his hand and to clamp it with his fingers.

The body 24 includes reliefs 26 on the surface to reinforce the adhesion between the body 24 and the hand 18.

The first part 16 includes an extension 28 configured to cooperate with the second part 20.

The second part 20 comprises a yoke 30 configured to cooperate with the extension 28 of the first part 16 and two branches 32, 34 configured to cooperate with the cylindrical section 12 of the handle 10.

According to one embodiment, the two branches 32 and 34 form a tubular portion 36 with a diameter substantially equal to or very slightly less than the diameter D0 of the cylindrical section 12 of the handle 10 to ensure a slight tightening between the tubular portion 36 and the handle. Each branch 32, 34 has a free end 32F, 34F substantially parallel to the axis A36 of the tubular portion 36.

The distance between the free ends 32F and 34F is:

less than the diameter D0 of the cylindrical section 12 of the handle 10, determined so that after an elastic deformation, the free ends 32F and 34F are separated by a distance greater than the diameter D0 of the cylindrical section 12 of the handle 10 to allow clip the second part 20 onto the handle 10.

Preferably, the tubular portion 36 has a height (dimension taken parallel to the axis A36) approximately equal to or greater than the diameter D0 of the cylindrical section 12 of the handle 10. These characteristics confer better retention of the second part 20 on the handle 10 .

The first and second parts 16 and 20 can be made of the same material. The first and second parts 16 and 20 are made of light material so as not to increase the mass held by the operator's hand 18 too much. The second part 20 is made of a material suitable for allowing sufficient elastic deformation to be able to clip it onto the handle 10.

According to another characteristic of the invention, the articulation 22 is a pivoting connection with a pivot axis A22 perpendicular to the axis A36 of the tubular portion 36 of the second part 20.

According to a first embodiment visible in Figure 2, the yoke 30 comprises two branches 40, 42 parallel, spaced apart by a distance allowing the insertion of the extension 28 of the first part 16. The two branches 40, 42 and the extension 28 each comprise a passage orifice 44 oriented perpendicular to the axis A36 of the tubular portion 36 and configured to house a cylinder 46 which forms the pivot axis A22.

According to another embodiment, the first part 16 comprises a yoke 30 and the second part 20 comprises an extension 28 configured to cooperate with the yoke 30 of the first part 16.

Whatever the embodiment, one of the first and second parts 16, 20 comprises a yoke 30 with two parallel branches 40, 42 between which is inserted an extension 28 provided on the other of the first and second parts 16, 20.

The cylinder 46 and the through orifices 44 have diameters substantially equal to form a pivoting connection.

According to one embodiment, the cylinder 46 comprises at least one bulge so that it can be mounted with a tight fit in at least one of the passage orifices 44. Thus, the cylinder 46 is held in the passage orifices 44.

According to another embodiment, at least one of the passage orifices 44 has a diameter slightly smaller than the other passage orifices 44 in order to be able to mount the cylinder 46 with a tight fit.

Whatever the embodiment, the cylinder 46, the branches 40, 42 and / or the extension 28 have shapes allowing the cylinder 46 to be held in the through orifices 44.

The branches 40, 42 of the yoke 30 comprise two faces 40F and 42F arranged opposite, approximately perpendicular to the pivot axis A22. The extension 28 comprises two lateral faces 28.1 and 28.2 parallel to each other and perpendicular to the pivot axis A22. The spacing between the lateral faces 28.1 and 28.2 is substantially equal to the spacing between the faces 40F and 42F of the branches 40, 42.

According to another characteristic, the extension 28 and the yoke 30 have shapes which cooperate and which are configured to maintain the second part 20 relative to the first part 16 according to the at least two different positions.

According to one embodiment, each branch 40, 42 of the yoke 30 comprises a first edge 48 and a second edge 50 parallel to the pivot axis A22. According to one configuration, the first edge 48 is parallel to the axis A36 of the tubular portion 36 configured to clip onto the handle 10, the second edge 50 and the first edge 48 forming an angle between 110 ° and 150 °.

The distance between the first edge 48 and the pivot axis A22 is substantially equal to the distance between the second edge 50 and the pivot axis A22.

The first edge 48 and the second edge 50 are connected by a joining edge 54 parallel to the pivot axis A22 and separated from the pivot axis A22 by a distance greater than that separating the first edge 48 and the axis pivot A22.

The articulation 22 comprises a substantially planar contact face 56, coincident with a base of the extension 28. The contact face 56 extends on either side of the extension 28 and is parallel to the pivot axis A22. This contact face 56 is configured to cooperate alternately with the first edges 48 or the second edges 50 of the branches of the yoke 30. The contact face 56 is separated from the pivot axis A22 by a distance substantially equal to the distance between the first edge 48 and the pivot axis A22.

According to the invention, the second part 20 is positioned relative to the first part 16 in the horizontal position (visible in FIGS. 1A and 3) when the second edges 50 of the branches 40, 42 of the yoke 30 are in contact or parallel with the contact face 56.

The second part 20 is positioned relative to the first part 16 in the vertical position (visible in FIGS. 1B and 4) when the first edges 48 of the branches 40, 42 of the yoke 30 are in contact or parallel with the contact face 56.

According to one configuration, in the second position illustrated by FIG. 4, the contact face 56 is parallel to the axis A36 of the tubular portion 36 configured to be clipped onto the sleeve 10.

The junction edge 54 being separated from the pivot axis A22 by a distance greater than that separating the pivot axis A22 and the first or second edge 48, 50, the gripper 14 remains in one or the Another position as long as the operator does not voluntarily force the first position to move to the second position or vice versa.

According to another embodiment, at least one of the faces 40F or 42F of the forms 40, 42 of the yoke 30 comprises hollow or raised shapes distributed around the passage orifice 44 which cooperate with complementary shapes provided on one of the lateral faces 28.1, 28.2 of the extension 28.

The gripper 14 allows the operator to firmly hold the handle 10 of the suction brush thanks to the ergonomic shape of the first part 16 which fits in the palm of his hand. The operator can orient the handle 10 differently from his hand 18, without needing to modify the inclination of his wrist, by modifying the position of the second part 20 relative to the first part 16 thanks to the articulation 22 Thus, the gripper 14 allows the operator to easily orient the handle 10 to follow the reliefs of the surface to be cleaned while exerting sufficient force to press the suction brush onto this surface.

According to a second embodiment visible in FIGS. 5 and 6, the gripper 14 comprises a first part 16 configured to be grasped by a hand 18 and a second part 20 configured to be clipped onto the handle 10.

According to this second embodiment, the first and second parts 16 and 20 are in one piece.

The second part 20 comprises a body 58 and at least a pair of branches 32, 34 which extend on either side of the body 58 and which are configured to cooperate with the cylindrical section 12 of the handle 10. As for the first embodiment, for each pair, the two branches 32 and 34 form a tubular portion 36 with a diameter substantially equal to or very slightly less than the diameter DO of the cylindrical section 12 of the handle 10, in order to ensure a slight tightening between the tubular portion 36 and the handle. Each branch 32, 34 has a free end 32F, 34F.

The distance between the free ends 32F and 34F is:

less than the diameter D0 of the cylindrical section 12 of the handle 10, determined so that after an elastic deformation, the free ends 32F and 34F are separated by a distance greater than the diameter D0 of the cylindrical section 12 of the handle 10 to allow clip the second part 20 onto the handle 10.

According to a configuration visible in FIGS. 5 and 6, the second part 20 comprises a first pair of branches 32, 34 and a second pair of branches 32 ', 34', the first and second couples being offset in a direction parallel to the axis A36 and connected by the body 58 which is parallel to the axis A36.

The first part 16 comprises a handle 60 which extends in a plane containing the axis A36, in a direction approximately perpendicular to the axis A36.

According to one configuration, the body 58 and the handle 60 have a U-shape, the body 58 forming a first branch 62 of the U and the handle 60 forming a base 64 and a second branch 66 of the U.

The base 64 and the second branch 66 of the U form approximately a stick and have an ergonomics adapted to be grasped by a hand of an operator. The base 64 is substantially perpendicular to the axis A36 and the second branch 66 is substantially parallel to the axis A36.

The base 64 is arranged in the extension of a first pair of branches 32, 34.

The second part 20 includes a boss 68 positioned on the body 58 on a face opposite to the second pair of branches 32 ', 34'. This boss 68 has approximately a half-sphere shape and a palmar ergonomics, adapted to the palm of a hand 18 of an operator.

Advantageously, the boss 68 and the handle 60 are hollowed out to reduce the mass of the gripper 14.

According to this second embodiment, the handle 10 of the tool can be positioned horizontally when the operator grasps the gripper 14 by tightening the handle 60 with his hand. In this position, the knuckles of the operator's hand can bear against the boss 68. The handle 10 of the tool can be positioned vertically when the operator grasps the gripper 14 by positioning the boss 68 in the hollow of its hand and tightening the body 58 of the gripper 14 and the handle 10.

The gripper 14 allows the operator to firmly hold the handle 10 of the suction brush thanks to its ergonomic shape. The operator can orient the handle 10 differently from his hand 18, without needing to modify the inclination of his wrist, by modifying the grip of the gripper. Thus, the gripper 14 allows the operator to easily orient the handle 10 to follow the reliefs of the surface to be cleaned while exerting sufficient force to press the suction brush on this surface.
