Definitions

• the subject of the present invention is a squeegee equipped with an easy-to-change cleaning blade.
• the squeegees referred to in the present invention are those manual tools equipped with a handle that, at one end, supports a structure perpendicular to the handle that supports a scraper blade, where such manual tools are skilfully operated by the user across a flat and smooth glass surface, rendering said surface clean and dry after it has been wet or washed, without requiring any additional steps.
• Squeegees are cleaning devices that take on particular characteristics in the field of professional cleaning.
• the front blade of the tool should have a sharp overhanging edge that rests against the glass surface.
• This replacement may also be necessary in the middle of a job that does not allow long breaks in comfortable situations, but instead may occur during a job with tight and limited time constraints times to finish and in very uncomfortable situations.
• the replacement of the accessory involved the assembly of the front part clamped into a supporting metal profile.
• the scraper blade generally consists of a polymeric, resinous or rubbery material, or other materials that do not abrade the glass surface, and which, therefore, do not have a high elastic modulus and due to the length they have, usually a few decimetres, require a supporting structure, often a metal profile.
• the front blade is now a separate and distinct accessory, or in any case one that can be detached from the metal profile, and one that can therefore be removed from the longitudinal slot of the metal profile, as it is not permanently clamped in place anymore.
• the task of this metal profile is not only to impart a straight configuration to the scraper blade, but also to retain it transversally to the direction of insertion within the profile.
• These retaining blocks can be released to allow the blade to be removed longitudinally from the metal profile and replaced with a new one.
• a different configuration of the squeegee that allows for the easy replacement of the blade provides a kinematic handle for the release and retention of the metal profile together with the blade that it supports.
• Said mechanism therefore has two stable positions, namely a first position for retaining the assembly consisting of the metal profile and the scraper blade supported by it, and a second position for releasing said metal profile and the blade that it supports.
• the change between the two stable positions of said mechanism is carried out by means of a control located on the handle, which is operated by the operator as needed.
• the operator after making sure the profile has been correctly positioned within the profile clamp, uses said mechanism control again to close the clamp's jaws to secure the support, along with the new blade, to the handle and also the scraper blade to the handle. Only at this point can the operator resume cleaning the glass surface with an efficient squeegee.
• the object of the present invention is to provide a squeegee that has an easier system for changing the cleaning blade that overcomes one or more of the previously mentioned drawbacks.
• a further object of the present invention is to provide a squeegee that allows the cleaning blade to be easily changed even with one hand.
• Another object of the present invention is to provide a squeegee that allows for a versatile retention of the different accessory components.
• Yet another object of the present invention is to provide a squeegee that does not require, for the retention of the cleaning blade, any element placed at the ends of the profile that retains said cleaning blade.
• An equally important object of the present invention is to provide a squeegee that makes it possible to replace the scraper blade even with only one hand.
• said first position where the mouth is closed and locked corresponds to the minimum opening of the mouth.
• said second widening position of the mouth of the clamp corresponds to a stable position of the control of the opening mechanism, allowing the operator to remove the scraper blade from the retaining profile, where said profile is in turn held within the clamp, holding the squeegee firmly through its handle.
• said second widening position of the mouth of the clamp corresponds to a slight opening of the jaws of the clamp that retains the retaining profile and that leaves the scraper blade free to slide within the groove of said profile.
• said third widening position of the mouth of the clamp corresponds to a position of the control even more beyond the stable positions and under the effect of elastic devices that tend to return the control back to one of the two stable positions and ideally to said second stable position.
• the third widening position of the mouth of the clamp is configured as a rotation of a jaw around its own pivot point moved directly by said control lever.
• said control lever of the mechanism is positioned on the handle, making it easier for the operator to use.
• said lever of the mechanism is enclosed within the perimeter profile of the handle and/or clamp in the first closed position.
• said lever of the mechanism extends beyond the perimeter profile of the handle and/or the clamp by at least the third closing position.
• said three different positions of the control of the mechanism correspond to three positions rotated around a hinge pin of a jaw of the clamp mouth.
• the fixed and stably retained position of the retaining profile within the mouth of the clamp is ensured, and is achieved by overcoming an initial interference involving a toggle mechanism, with which the mechanism is equipped, with respect to a fixed part of the clamp or handle.
• the squeegee 1 of the invention which comprises a handle 2, a clamp 3 and a scraper blade held by a retaining profile.
• Said clamp 3 comprises an upper jaw 4 and a lower jaw 5.
• the lower jaw 5 is movable, attached to a hinge pin 6 with a groove in common with the upper jaw 4.
• the rotation of the lower jaw 5 is controlled by a mechanism 7 equipped with a manually operated control lever 8.
• said control lever 8 is located on the handle 2 or on the clamp 3.
• Said control lever 8 can take on three positions, of which at least two are stable, which have an effect on said mechanism 7 to which three increasing situations of separation of the clamp 3 correspond. To the different degrees of opening of the mouth of the clamp 3 correspond different situations for the retention and/or release of the retaining profile assembly and the scraper blade.
• the squeegee 1 keeps the retaining profile 9 securely attached to the end of the handle 2, by means of the clamp 3, in whose groove 10 the scraper blade 11 is.
• Said normal configuration corresponds to a first position of the control lever 8, integrated and not protruding, but within the perimeter profile of the handle 2.
• Said varied and protruding position of the control lever 8 corresponds to the second stable position of the control lever that, by acting on the locking/fixing - opening mechanism 7 of the clamp 3 configures the jaws 4, 5 in a divergent spaced situation between said jaws.
• the lever resting on the movable lower jaw 5 of the clamp 3 pushes it to rotate, around the hinge axis 6 in common with the fixed upper jaw 4, leading them to an opening of the mouth that allows the retaining profile 9 to move away from the clamp 3 itself.
• control lever corresponds to the third possible position of the lever 8, which is not stable, and is returned to the second stable position by means of elastic devices 13 connected with or included in the mechanism 7 for opening the mouth of the clamp.
