Description

ceiling application tool

[0001] The invention relates to an application tool for ceiling or wall or floor. Prior art

[0002] The invention relates to a tool for applying, spreading and smoothing a coating or paint for a ceiling.

[0003] Currently, the application of paint or coating to a ceiling is done using a tool comprising a handle at the end of which an application element is arranged. This tool is held by the operator via the handle with both hands. The operator makes a movement, for example back and forth, with the tool on the surface of the ceiling in order to coat or paint it. The handle can be adjustable depending on the operator's height.

[0004] However, the disadvantage of this tool is that it requires the operator to have their arms at a height as visible to the operator to carry the tool while moving them to spread the coating or paint. Such a position is uncomfortable and can ultimately lead to musculoskeletal disorders. Indeed, when using the tool, the entire weight of the tool rests on the operator's arms. In addition, the operator must constantly look at the ceiling to ensure contact between the tool and the ceiling and for guidance.

[0005] The present invention aims to provide a tool that solves the problems of the prior art by providing a more comfortable coating / paint application tool.

[0026] - represents a view of a support with receiving surface oriented for application on the ground; Detailed description of the invention

[0027] The invention shown on the shows an application tool 10 according to the invention. The application tool 10 comprises a handle 11 in the form of a rod or a tube. On a first end of the handle, an application element 12 is arranged. This application element 12 is an element allowing a coating or paint or the like to be applied, spread on a surface. For example, the application element 12 is in the form of a roller or a trowel or a scraper. The application tool makes it possible to apply, spread, smooth a coating or an adhesive or a paint or a sealant or any other spreadable material.

[0028] The handle 11 is arranged to be adjustable to adapt to the morphology, more precisely the size, of the operator as visible in the. For this, the handle 11 comprises two portions sliding one inside the other and associated with a locking means for locking the portion of the two portions 11a, 11b relative to each other.

[0029] According to the invention, the tool 10 is associated with a support 20 to form an application assembly 1. This application assembly 1 is in the form of a kit.

[0030] The support 20 comprises a receiving surface 22 as visible in the. This receiving surface 22 is arranged to cooperate with the second end of the handle. Indeed, the second end of the handle 11 comprises a support head 14. This support head 14 has a shape such that it cooperates with the receiving surface 22 of the support 20. This cooperation allows the handle 11 to bear on the support. The handle 11 thus supported by the support 20, the operator does not need to raise his arms to bring the support and the application head to the ceiling as visible in the.

[0031] In a first embodiment visible in the, the support head 14 is of circular, spherical shape. The receiving surface is also of substantially circular, spherical shape.

[0032] The support head 14 has a partially spherical shape and the receiving surface 22 has a concave shape, preferably inverse to this partial sphere. This first embodiment allows the partially spherical shape of the support head to cooperate perfectly with the inverse shape of the receiving surface. Thus, once the handle 11 is supported on the support, this allows the operator to move the handle. The movement zone of the handle is a cone, it is then understood that the support head is the apex of this cone-shaped movement zone. Furthermore, this embodiment allows the handle 11 to be moved without constraining the support 20.

[0033] The support head 14 is preferably semi-spherical, and even more preferably spherical as seen in the figure. In this case, the receiving surface 22 is partially spherical, semi-spherical or in the form of a cylinder provided with a partially spherical bottom. The receiving surface is thus in the form of a housing. In this case, the support head 14 is wedged in the receiving surface 22, thus preventing said support head from coming out.

[0034] In a second embodiment visible in the, the support head 14 has a triangular or parallelepiped shape. The support head is then, optionally, connected to the handle by a ball joint system 14' as visible in the. The support head 14 is capable of being inserted into the receiving surface 22 which is in the form of a housing, the shape of which allows the support head to be fitted into said housing. The combination of the triangular or parallelepiped shape with the ball joint system 14' makes it possible to prevent the support head from coming out of its housing while ensuring good maneuverability of the tool.

[0035] This second embodiment allows the support head 14 to be held in the housing while allowing the handle 11 to move in a cone thanks to the ball joint.

[0036] According to the invention, the support 20 is arranged to be worn by the operator as visible in the. The support is then associated with a fastening element 30. This fastening element 30 is in the form of a belt or a harness. Such a belt or harness is attached to the operator. In operation, the operator equips himself with the harness 30 or the belt 30 and attaches it. He then equips himself with the application tool. He adjusts the length of the handle, if possible, and makes the support head cooperate with the receiving surface as visible in the. This cooperation between the support head 14 and the receiving surface 22 makes it possible to block the application tool 10 with the receiving surface as visible in the. Since the receiving surface of the support is part of the fastening element (belt or harness), the application tool 10 is therefore carried by the operator's body, not his arms.The operator's arms are then used to move the application tool and apply the coating or paint.

[0037] In one variant, the handle 11 of the application tool 10 is arranged so that the application head 12 is angularly adjustable. This angular adjustment makes it possible to have an angle between the axis of the handle and the application head to improve the handling of the application head. For this, several solutions are possible.

[0038] The first and simplest solution consists of having an application head that is interchangeable. It is then understood that the application head is an added part as visible in the figure. This application head 12 is then fixed to the handle 11 by screwing or snapping or by bayonet fixing. In this solution, the application head is then associated with a fixing portion which consists of a tubular portion fixed to the handle.

[0039] This solution allows you to mount an application head that has a curved attachment portion or that has an angle relative to the axis of the handle.

[0040] A second solution consists of having an application head 12 mounted pivotally as seen in the figure. For this, a first assembly consists of having a pivoting interface between the handle 11 and the application head 12. This pivoting interface comprises a ball joint or a universal joint or a fork carrying an axle. This pivoting interface allows the application head to be pivoted through at least 180 degrees. This pivoting interface thus allows the application head to remain pressed against the surface to be coated during application by the operator and his movements of the tool.

[0041] Of course, the first solution and the second solution are not incompatible. Indeed, it is possible to have an application head mounted pivoting on a ball or gimbal but which is also an added part.

[0042] Of course, the present invention is not limited to the illustrated example but is susceptible to various variants and modifications which will appear to those skilled in the art.

[0043] Indeed, if the invention described can be used for the application of coating or paint on a ceiling, it can also be used for application on walls, particularly for very high walls.

[0044] The invention can also be used for coating floors. In this case, the receiving surface is positioned on the support accordingly as visible in the. More particularly, the receiving surface is oriented in a direction parallel to the ground unlike the position of the receiving surface which, for an action of coating a ceiling, will be oriented in a direction perpendicular to the ground plane.
