Description

Technical field of the invention

The present invention relates to an orientation cup. In particular, the present invention relates to an orientation cup for receiving the tip of a spray paint.

State of the art

To draw lines on the ground, it is known to use a carriage equipped with a spray of paint.

So that a line on the ground has substantially the same color over its entire width, but also a regular width with a uniform distribution of paint over the entire width, it is known to use an aerosol whose tip is capable of projecting painting in a preferred direction, perpendicular to the direction of travel of the carriage. When placing the aerosol in the carriage, it is therefore necessary to properly orient the tip of the aerosol relative to the direction of travel of the carriage.

Even if the tip has a shape that helps this positioning, for example as in the document USOOD424662S this operation can be a source of delay and inaccuracy.

The document FR 2439723 discloses an orientation cup for aerosol nozzle, comprising a housing having a bottom wall and a side wall.

Summary of the invention

A problem that the present invention proposes to solve is to facilitate the positioning of the nozzle of an aerosol.

The solution proposed by the invention is an orientation cup for aerosol nozzle, characterized in that it comprises a housing having a bottom wall and a side wall, said side wall having a first frustoconical surface and a second frustoconical surface image of the first frustoconical surface by rotation of 180 ° about an axis A, the distance between said first frustoconical surface and the axis A being increasing as a function of the distance along the axis A from the wall of bottom, the distance between said first frustoconical surface and the axis A being variable as a function of an angle of rotation about the axis A.

Thanks to these characteristics, the first and second frustoconical surfaces define an opening of larger dimensions than the bottom wall. The insertion of a mouthpiece in the housing is therefore facilitated. In addition, during the progressive depression of the nozzle in the housing, the cooperation between the tip and said frustoconical surfaces allows to rotate the tip to give it a specific orientation.

Advantageously, the side wall has a third frustoconical surface adjacent to the first frustoconical surface, a first flat located between the third and second frustoconical surfaces, a fourth frustoconical surface adjacent to the second frustoconical surface and a second flat located between the fourth and first frustoconical surfaces.

Preferably, said bottom wall is traversed by an orifice.

According to one embodiment, the perimeter of said bottom wall has two semicircles and two parallel straight segments connecting said semicircles.

The invention also provides a paint carriage comprising an aerosol container and a cup according to the invention above arranged in said receptacle.

Detailed description of an embodiment of the invention

The Figures 1 to 5 represent a cup 1 intended to be installed in a paint carriage. More specifically, the cup 1 is intended to receive and orient the flat nozzle of a spray paint.

The document US00D424662S is an example of a flat jet nozzle. It comprises a first stage having a nozzle, a second cylindrical stage, whose section has two semicircles connected by two straight segments, and a third stage of larger dimensions.

The cup 1 comprises a disk 2 and a protrusion 4 projecting from a face of the disc 2. The protrusion 4 defines a housing 5 open in the center of the disc 2, and intended to receive the tip of an aerosol. The cup 1 also comprises a stud 9 connected to the edge of the disc 2. The disc 2, the protrusion 4 and the stud 9 can be made in one piece, for example by injection molding.

The disk 2 has a circular central zone 3 of reduced thickness, which surrounds the opening of the housing 5.

The housing 5 has a bottom wall 6 and a side wall 7. The edge of the bottom wall 6 comprises two semicircles connected by two straight segments. The bottom wall 6 is traversed by an orifice 8.

The side wall 7 has a shape represented in particular on the Figures 1, 3 and 5 . When we go figure 3 clockwise, the side wall 7 comprises successively a frustoconical surface 10, a frustoconical surface 13, a flat part 15, a frustoconical surface 11, a frustoconical surface 12 and a flat part 14.

The frustoconical surface 13, the flat 15, and the frustoconical surface 11 are respectively images of the frustoconical surface 12, the flat surface 14 and the frustoconical surface 10 by rotating 180 ° about an axis A passing through the center of the orifice 8. They will not be described in detail.

The frustoconical surface 12 extends from the edge of the bottom wall 6 to the disk 2. It has an open circular arc section of approximately 90 °, a larger radius of curvature at the disk 2 than at the level of the disk. bottom wall 6.

The flat 14 extends from the edge of the bottom wall 6 to the disk 2. It is slightly inclined so as to be further from the axis A at the disk 2 than at the level of the bottom wall 6. flat 14 is connected to the frustoconical surface 12 by an edge 18 and the frustoconical surface 10 by an edge 17. The ridges 17 and 18 are inclined towards one another and meet at the disc 2.

The frustoconical surface 10 extends from the edge of the bottom wall 6 to the disk 2. It has a section, taken in a plane perpendicular to the axis A, whose distance to the axis A varies according to an angle θ of rotation about the axis A. The frustoconical surface 10 has larger dimensions at the disk 2 than a level of the bottom wall 6.

In other words, the frustoconical surface 12, the flat 14 and the frustoconical surface 10 are inclined with respect to the axis A. The housing 5 thus has an opening, at the disc 2, of larger dimensions than the bottom wall 6 This facilitates the insertion of a tip of the type mentioned above, the second stage of which has dimensions corresponding to those of the bottom wall 6, in the housing 5.

Moreover, when inserting said tip in the housing 5, it is sufficient to ensure that the semicircular edges of said second stage come into contact with the frustoconical surfaces 10 and 11. As and when pushes the nozzle into the housing 5, the frustoconical surfaces 10 and 11 cooperate with the nozzle to rotate it. When the tip is fully inserted into the housing 5, with its first stage passing through the orifice 8, its second stage rests against the bottom wall 6.

In this state, the side wall 7 maintains the orientation of the tip. Indeed, the frustoconical surface 12, the flat 14 and the frustoconical surface 10 extend from the edge of the bottom wall 6. The side wall 7 thus has, in the vicinity of the bottom wall 6, a section corresponding to the section of said second floor. In particular, the flats 14 and 15 are slightly inclined relative to the axis A. For example, their inclination is less than 5 °. They keep the tip in place.

The cup 1 thus allows to orient the tip of a spray paint in a predetermined direction. This can be done easily because it suffices to ensure, when inserting the nozzle in the housing 5, that the tip comes into contact with the frustoconical surfaces 10 and 11. It is not necessary to give the tip a precise orientation before inserting it into slot 5.

Thanks to the stud 9 and holes 16 drilled in the stud 9 and the disc 2, the cup 1 can itself be arranged in a carriage in a predetermined orientation. The cup 1 thus makes it possible to orient the tip of an aerosol in a predetermined position with respect to a carriage.

Although the invention has been described in connection with a particular embodiment, it is obvious that it is not limited thereto.
