SURFACE RENOVATION DEVICE

The invention relates to the field of devices for renovating surfaces, in particular for renovating large surfaces such as floors, using renovation tools using brushes or rotary rollers.

The invention does not relate to devices using rotary disc tools of the grinder disc, sander type.

It is known to use portable surface renovation tools to strip, brush, renovate small wooden surfaces, such as wooden furniture surfaces, or small metal surfaces, using a rotating cylindrical element. such as a brush or a rotating roller.

In the remainder of the description, the term “roller surface renovation” means the function of rubbing, pickling with the aid of means in the form of a rotary cylindrical element of the roller or brush type, the active friction surface of which is suitable for the type of surface to be renovated. For example, the active surface of the roller may be made of felt, or of abrasive paper (with continuous surface or in the form of strips), or even provided with plastic or metallic brush bristles, etc.

More particularly, a roller surface renovation tool comprises, in known manner, a slender body housing electrical drive means of the electric motor type, and the distal end of which forms gripping means, at least one rotary cylindrical renovation element. , such as a brush or a roller, capable of rotating in rotation via the electric drive means transversely to the elongate body, and a casing partially open and partially covering the cylindrical element.

Generally, such a tool implements a roller of about ten centimeters. Therefore, it is not suitable for medium and large areas. Increasing the length of the roller therefore proves to be a solution for renovating a larger area. However, on the one hand the more bulky roller increases the weight of the tool, and on the other hand, it requires a more efficient motor to ensure its rotation efficiently, generating a heavier motor. Consequently, providing rollers with a larger treatment surface ultimately increases the weight of the tool. The tool becomes more difficult to handle, and its weight quickly becomes a nuisance for the user.

The invention therefore aims to overcome the aforementioned drawbacks by providing a roller renovation device, used to renovate large areas, including a floor, the device being easily manipulated, easy to use, and allows the user adopt an ergonomic posture while standing.

According to the invention, the surface renovation device, in particular the roller surface renovation, comprises a roller surface renovation tool comprising a slender body housing electrical means for rotary drive, and at least one cylindrical element of the roller type able to rotate via said drive means, and having an active renovation surface, and is characterized in that it comprises a movable support on which is adapted to be disposed the renovation tool, in particular the tool being removably attached to the support, and a gripping means, in particular in the form of a handle, preferably telescopic, associated with the mobile support and / or the renovation tool.

The device with renovation function 1 illustrated by way of nonlimiting example in FIGS. 1 to 4 is intended to renovate surfaces, more particularly floors.

The renovation device 1 is a roller renovation device. It comprises a tool with renovation function 2 with a roller, a mobile support 3 on which is intended to be arranged the tool 2 for the use of the device, and a gripping means 4 of the handle type, associated with the support 3 and / or with tool 2 to operate the mobile support and consequently the tool on the surface to be renovated.

The renovation tool 2 is provided with means suitable for surface renovation in the form of at least one rotary cylindrical element with active renovation surface.

The renovation tool 2 comprises a slender body 20 housing electrical means for rotary drive such as an electric motor, a cylindrical element 21 of the roller type (visible in FIG. 4) capable of turning via the electric drive means. rotary, a partially open casing 22 partially enveloping said cylindrical element 21. The elongated body 20 is of the usual type for portable electric tools; it has a distal end 20A serving as a handle, comprising an on / off switch for the tool, and from which an electrical cable 20C exits, an opposite distal end 20B from which, from the so-called internal face of the body, projecting laterally and transversely to the elongate body a rotary shaft 20C on which the roller 21 is mounted. The roller 21 is fixed to the shaft in a removable and known manner. It has an active renovation surface over the entire periphery of its cylindrical body, this surface being made of a material suitable for the type of surface to be renovated.

The casing 22 partially envelops the roller 21. It is not in direct contact with the roller so as not to hinder the rotary movement of the roller.

According to the invention, the casing 22 constitutes a half-shell; it has a hollow semicylindrical shape. In the variant shown, which is in no way limitative, the section of the demohull is polygonal, a purely aesthetic characteristic. The casing, possibly combined with the lateral face of the elongate body 20, covers the upper part of the roller

21, as well as the two lateral faces of the roller transverse to the cylindrical axis of the roller.

In the position of use of the device (Figures 1 and 3), the roller 21 is hidden from the user. Thus, the dust from the pickling during the operation of the roller remains confined inside the casing to fall on the ground or preferably be sucked, in particular at the rear of the casing, by suction means not illustrated and intended to be connected to the housing.

The casing 22 and the elongated body 20 are preferably in one piece, at least without being easily dissociable from one another by the user.

The housing 22 comprises a body 22A of longitudinal axis extending along the rotary shaft of the tool, at each end of the two lateral faces of the half-shell, faces transverse to the longitudinal axis of the housing, a cheek of 22B said inner closure while facing the elongate body 20, and an opposite 22C cheek said outer, located on the side outside the tool.

The outer closing cheek 22C is removable so as to be able to mount / dismount the roller 21 of the rotary shaft. It is fixed by removable fixing means 22D such as by bolting.

Preferably, the gripping means (the handle) 4 is associated not only with the support 3, as described below, but also with the casing 22.

To this end, in one embodiment, the casing 22 comprises on the external face of the longitudinal body 22A and parallel to said body, a pivoting bar 23 (Figures 1 and 3). The pivoting bar 23 is mounted on a longitudinal axis or two end axes connected to two opposite and parallel flanges 23A and 23B which are fixed to the casing. The pivoting bar 23 has in its central part removable fixing means 24 for cooperating with the lower distal end 40 of the handle 4.

This connection of the handle 4 to the housing 22 according to a pivoting connection facilitates the handling of the renovation device 1 for the user, in particular allowing the user to exert if necessary easily a force of pressure on the tool to further compress the roller 21 against the surface to be renovated, and / or tilting the support 3 and therefore tilting the roller 21 further on the front of the device, providing a larger attack surface with the surface to be renovated.

The pressure exerted on the roller 21 is obtained directly by the user by means of the handle 4 connected to the tool.

In addition, the casing 22 may comprise a fixed longitudinal handle 29, parallel to the swivel bar 23, as illustrated in the variant of FIG. 2b, to more easily grasp the tool when it comes to installing it or remove it from the support 3.

Furthermore, the casing 22 can be connected to suction means of which the suction pipe 5 is illustrated in FIG. 5. The body 22A of the casing comprises (FIG. 4) on its rear face, in a vertical plane, at least one discharge outlet, which here cooperates with connection means 25 integral with the support 3, the suction means being intended to connect to the connection means 25. The discharge outlet of the casing and / or the means 25 for connection of the support are preferably closable, for example by a removable plug, when the user does not wish to connect the pipe 5.

The mobile support 3 is designed to carry the renovation tool 2 so that the roller 21 projects below the support 3. The support can have different shapes.

A preferred example is shown in FIGS. 1 to 4. The support 3 comprises a plate 30 provided with a hole 31, here in the shape of an L to accommodate the lower part of the distal end 20B of the elongated body 20 of the tool , and the roller 21, the body 22A of the casing and the rest of the body 20 resting on the plate.

The tool 2 is removably attached to the support 3, via the casing 22, by means of removable securing means 2A, for example by bolting or quick-fixing systems such as latches (FIG. 7). The support 3 and the casing 22 advantageously comprise mutual cooperation members in order to associate therewith the removable securing means. For example, for fastening by bolting, the support 3 comprises fixing lugs each provided with an orifice cooperating with an orifice opposite the casing.

Preferably, the housing 22 is fixed at its lateral cheeks 22C and 22B. The support 3 is made mobile via preferably two rollers 32 and 33 which are integral with the underside of the plate 30 and arranged opposite the roller 21, at the rear of the plate. The rollers arranged only at the rear of the support 3 provide a cantilever position of the support, allowing the inclination of the tool and therefore of the roller towards the front of the device.

Furthermore, in this embodiment, the gripping means (the handle) 4 is associated with the support 3, advantageously removably, via an interface piece 6 fixed on the plate 30 and at the rear of the support. This interface piece 6 extends in height to support a proximal part of the handle 4, at a distance from the distal end 40 of the handle which is associated with the casing 22. This piece 6 is also pivotable about an axis parallel to the rear side of the support, parallel to the swivel bar 23, and to the roller 21.

Finally, the handle 4 is preferably telescopic. In addition, it has at its upper distal end 41, a handle 42, and preferably a second handle 43 extending transversely to the longitudinal body of the handle and adjustable in height along the handle. Advantageously, the handle 4 comprises hooking and / or winding means 44 making it possible to carry the electric cable 20C of the renovation tool 2. For the electrical operation of the renovation device 1, an electric extension cord connected to the mains will be used to connect the electrical outlet of cable 20C of the renovation tool 2 to said extension cable, and therefore to the mains.

FIGS. 6 to 8 illustrate variants as to different constituent elements of the renovation device of the invention.

FIG. 6 illustrates a variant of the gripping means 4. The gripping means 4 comprises on the one hand at its distal end 41 and its handle 42, an electric cable 45 intended to be connected to the mains, and d 'other hand, an electrical outlet 46 integrated into said handle, and on which is intended to connect the electrical cable 20C of the tool 1. In yet another variant, the electrical supply could be done by passing inside the handle 4 advantageously hollow.

In addition, the lower distal end 40 of the handle 4 is removably associated in another way on the casing 22 (Figures 7 and 8). Said end 40 comprises a jaw 40A engaged astride a longitudinal bar 27 of the casing, the bar 27 here being non-pivoting. The bar Y1 advantageously also constitutes a handle for the tool. The bar 27 is cylindrical with a circular circular section, while the jaw has on its internal face a complementary geometric shape so as to allow the pivoting of the handle 4 around the cylindrical axis of the bar. A locking system 28 is provided for holding the jaw 40A in position on the bar 27. In this embodiment, the connection between the handle 4 and the casing 22 is also pivotable so that the user can more easily handle the device and exert the appropriate pressure forces on the roller directly from the handle.

In this variant also (FIGS. 6 and 7), the removable securing means 2A connecting the casing 22 to the support 3 to fix the tool 2, are latches.

Finally, in the variant of Figure 9, the support 3 is not in the form of a substantially horizontal plate but in the form of a frame comprising two opposite flanges connected together by support bars for a part support the tool 2 in an inclined manner so that the roller 21 is in contact with the ground, and secondly, to fix the handle 4.

Also in this variant, the renovation device comprises an interface pipe 50 for connection between the connection means 25 of the support 3 and suction means (here not shown) which are intended to connect to said interface pipe 50 whose connection outlet is arranged at the level of the handle 4. Again in this variant, the handle 42 of the end of the handle 4 can be adjustable in position. The handle 4 may include the connection and the electrical supply to the tool 2. The handle 4 may include an actuating member 47 connected to a speed controller to control the speed of rotation of the roller 21 of the tool .

The different variants illustrated with regard to certain elements of the device can be used independently of the type of mobile support envisaged. Finally, the mobile support could be distinct from the versions illustrated here.
