Description

The present invention relates to a device in the building sector and more particularly to a device for joining two plasterboards and even more particularly to a device for humidifying, depositing and cutting a strip of paper in order to finish the joining of two plasterboards located on a wall or ceiling, working on the floor.

Several types of devices for depositing a strip of paper are known from the prior art.

The first is a device for coating the tape before applying it. However, this device has many drawbacks. Indeed, this device becomes dirty very quickly, thus requiring frequent cleaning of the device.

In addition, the device of this type is generally short, preventing the application of the tape at the top of walls and on ceilings when a user does not have a ladder, stilt or stepladder available.

The user is therefore obliged to bring a ladder, stilt or stepladder to join the top of the walls and the ceilings, increasing the risk of accident for the user.

Finally, this device does not include means making it possible to cut the strip when it has been applied, for example on a wall, the user is therefore obliged to cut the strip himself when it has finished being used. applied and manually remove it again to start a new application.

Another type of device, more elaborate than the first presented above, is also known. In addition to coating the tape to be applied, this device comprises means for cutting the tape when the application of the tape is completed. However, this device is imposing. Indeed, it has a high weight and is difficult to maneuver for a single user.

In addition, when this device cuts the strip, it is not certain that the remaining length of the strip makes it possible to complete the joint of the two plasterboards in its entirety, causing an additional gesture on the part of the user, in order to to engage the next strip on the means for applying the strip.

Finally, these devices do not allow the strip to be humidified before it comes into contact with the coating. In fact, humidification appreciably improves the adhesion of the strip and of the coating, in particular in hot weather.

A deployment cable 52 is configured to connect the actuating trigger 78 to the caster 16 (shown in FIG. figure 3 ) to one of the arms 17 of the caster 16, passing through the pulley 51 so that, when the trigger is actuated, the arms 17 are configured to drive the caster 16 from an inactive position to an active position. On this figure 9 , the wheel 16 is in the inactive position, that is to say that the wheel is substantially in the direction of the trigger. Conversely, in the active position of the wheel 16, the latter is in a direction substantially opposite to the direction in its inactive position.

A torsion spring (not shown) allows caster 16 to be returned to its inactive position.

Deployment of the roller 16 from the active position to the inactive position is achieved by manual release.

The figure 10 partially illustrates the depositing means 13 and the cutting means 19. The toothed wheel 14B is inserted in a groove 53B arranged in the blade support 46 so as not to block the movement of the toothed wheel 14B.

In addition, the sheet 32, the end of which comprises the return 45, is connected to the blade support 46 by two fingers 54 (only one is visible). This finger 54 is inserted into an oblong hole 55 of the blade holder 46 and is configured to slide in this oblong hole 55.

The connecting means 34, here a pin, connecting the blade support 46 to the movable guide 36, is L-shaped. The right angle forming the L is configured to receive a cylindrical support 56, fixed on an inner face 37 and side 38 of the casing 29 and projecting towards the inside of the casing 29, making it possible to consolidate the movements effected by the connecting means 34.

The figure 11 shows a first embodiment of the cutting means 19.

In this first embodiment, the cutting means 19 comprise a blade support 46. This blade support 46 comprises two grooves 53A and 53B configured. to receive the corresponding toothed wheels 14A and 14B, thus breaking down the blade support 46 into three parts 57A, 57B and 57C.

The first part 57A, corresponding to the central part of the blade support 46, comprises a first recess 58 disposed on one end and configured to fix the connecting means 34 configured to connect the movable guide 36 to the blade support 46. This first part 57A of the blade support 46 also comprises two oblong holes 55 configured to receive the corresponding finger 54 connecting the sheet 32 to the blade support 46.

Finally, the first part 57A of the blade support 46 comprises two other recesses 59 configured to fix a central blade 60 by a screw-nut system 61, the two recesses 59 being arranged on an end opposite the end receiving the first recess 58 .

This central blade 60 comprises sharp teeth, the arrangement of which forms a V.

The second and third parts 57B and 57C, corresponding to the lateral parts of the blade support 46, each comprise two adjacent orifices 62A and 62B and arranged at the same end as the end of the first part 57A receiving the central blade 60. These orifices 62A and 62B are configured to receive a corresponding screw 63A and 63B, fixing two side blades 64A and 64B.

The figure 12 shows a second embodiment of the cutting means 19.

The only difference with the first embodiment illustrated on figure 11 , the blade support 46 does not include side blades 64A and 64B attached to the second and third parts 57B and 57C of the blade support 46.

Indeed, each of the second and third parts 57B and 57C have undergone a notch 65 thus sharpening the end of the second and third parts of the corresponding blade support 46.

The figures 13 to 15 illustrate a variant of the invention relating to the actuation of the cutting means 19 of the device 1. As illustrated in FIG. figure 15 , the device 1 comprises a sliding handle 110, slidably mounted on a section 111 extending along the extension axis A of the device 1 between an initial position and a final position. A sliding trigger 112 provided for actuation by a user is provided on the sliding handle 110 so as to allow it to slide on the profile 111.

A linkage system 113 comprising a rod 114 and a driving member 115, connects the sliding handle 110 to the cutting means 19 so that the sliding of the handle 110 between the initial position and the final position causes the displacement of the means of cut 19 between the rest position and the cut position. Indeed, the movement of the sliding handle 110 generates a translation of the rod 114 along the same axis of extension A, which in turn causes a translation of the drive member 115 along an axis parallel to the axis d 'extension A. The cutting means 19 fixed on the drive member 115 are then driven in translation between the rest position ( figure 13 ) and the cutting position ( figure 14 ).

Also shown on figures 13 and 14 , the device 1 comprises a tension cam 116 configured to cooperate with the strip 7 so as to place it in a tensioned position, favoring cutting by the cutting means 19, or a relaxed position when the cutting means 19 are in the position of rest.

The tension cam 116 is in fact configured to cooperate with the drive member 115 and to pivot between a relaxed position ( figure 13 ) and a tension position ( figure 14 ) when the drive member 115 is moved in translation between the initial state and the final state.

Thus the displacement of the drive member 115 allows the displacement of the cutting means 19 and the pivoting of the tension cam 116 concomitantly. Thus when the drive member 115 passes from the initial state to the final state, it causes the displacement of the cutting means 19 from the rest position and the cutting position, at the same time as the pivoting of the cam. tension 116 between the relaxed position and the tension position for tensioning the band 7. The figures 15 and 16 illustrate a longitudinal extension 120 of the device 1 according to the present invention. According to this arrangement, the device 1 comprises a section 111 extending along the extension axis A and configured for the gripping of the device 1 by a user.

The extension 120 is configured to fit in a reversible manner with an end portion 121 of the profile 111 allowing its elongation. In particular, the longitudinal extension 120 comprises a latching means 122 and the end portion of the profile 111 comprises a complementary latching means (not visible in the figures) configured for latching with the latching means 122 of extension 120.

Also shown on figures 15 and 16 , the longitudinal extension 120 also comprises a means for adjusting its length by the user. Indeed, the longitudinal extension 120 comprises a first tubular part 123 and a second complementary tubular part 124 and configured for sliding in the first tubular part 123 so as to reach the desired length of the longitudinal extension 120. A system of immobilizer 125 is also designed to immobilize the sliding of the second tubular part 124 in the first tubular part 123, so as to fix the length of the longitudinal extension 120.

In the following paragraphs, the operation of the present invention is explained. Before using the device 1, the areas of the plasterboard on which the strip 7 is to be applied are coated. A reel 6 of paper tape is inserted into the storage means 5 and the tape is unwound until it is placed on the sheet 32 so as to pass between the rollers 30 and the humidification means 24A and 24B and on the guides. 31 as well as the movable guide 36. The reservoir 18 is filled with water, via the stopper 72. Once filled with water, the reservoir is clipped onto the casing 29. The user also decides the position of the rollers 30 relative to the humidifying means 24A and 24B according to the humidification needs of the strip 7 to be applied. In fact, depending on the position of the rollers 30, the strip 7 will be more or less compressed against the humidification means 24A and 24B and therefore the strip will be more or less moistened. These humidification requirements of the band 7 can vary depending on the environmental conditions in which the room is located, for example the humidity level of the room or the temperature of the room.

A user takes over the device 1 by the first gripping element 2 and the second gripping element 4 in order to orient the depositing means 13, for example, in the direction of a wall 20 for which two plasterboards must be attached.

User can decide to apply tape 7 from bottom to top or top to bottom. Indeed, two humidification means 24A and 24B being present on each end of the reservoir 19, the strip 7 will be permanently moistened.

For example, when the user applies the strip 7 from bottom to top, the toothed wheels 14A and 14B will rotate around the axis of rotation corresponding to the pivot axis 15, in a counterclockwise direction until the wheels notched 14A and 14B are in abutments, both against the wall 20 and against the ceiling 21. When the notched discs 14A and 14B are in abutment against both the wall 20 and the ceiling 21, the entire length of the strip necessary at the joint of the two plasterboards is ensured.

The user can then actuate the trigger 26 making it possible to move, in a translatory movement, the cutting means 19 from the rest position to the cutting position.

When the trigger 26 is actuated, the traction cable 22 moves the cutting means 19 from the rest position to the cutting position by the pulley system 23. The movement of the cutting means 19 causes the movement of the means. link 34, for example a pin, connecting the blade support 46 to the movable guide 36 supporting the strip 7. The movable guide 36 will slide in the groove 39 and therefore no longer support the strip 7, thus making it possible to stretch the strip 7 so that the central blade 60 and the side blades 64A and 64B, or the sharp end of the second and third parts 58A and 58B of the blade holder 46, can easily cut the strip 7.

Once the strip 7 has been cut, the cutting means 19 are returned to their rest position by a tension spring 77, also returning the movable guide 36 to its initial position for supporting and guiding the strip 7.

In the event that the strip 7 is applied in a corner forming an angle, the user actuates the actuating trigger 76 of the caster 16 allowing the deployment cable 52 connecting the actuating trigger 76 to the arm 17 and passing a system. pulley 51 to move the caster 16 from a retracted position to an extended position allowing the caster 16 to press against the strip 7, which thus takes the shape of the wedge. Once the caster 16 is no longer needed, it can be returned to its retracted position by a tension spring.
