Abstract: The method begins with a metal strip deformed to form a tube, which outer face has been previously cleaned and conditioned to facilitate the adhesion of a first layer of adhesive material, on which a second layer of plastic material is applied and which is finally covered with a third layer, also of plastic material. The method used ensures the correct attachment of the different elements of the handle while providing a handle with a pleasant touch for the hands of the user. The handle obtained is more durable because it is perfectly protected against corrosion thanks to the three layers, each one of which is approximately 90 microns thick.

Abstract: A box includes, in principle, a plastic structure with a rectangular base, two ends, and two sides which are pivotably coupled to said base. The ends include centered parts combined with latches, which in one position anchor the sides and ends, while in another position said connection between the ends and the sides is released in order to collapse said elements and thus achieve a collapsed position. The box includes an anchor device consisting of a series of rotary bodies (5) that connect the bolts of the lock (4) to the centered part (1) via two pairs of resilient parts (6) and (7) which, in the inoperative position thereof, hold the bolts of the lock (4) outwards, attaching the ends (2) and the sides (9), and when the central part (1) is moved upward, the latches thus release the ends and the sides.

Abstract: A wringer for mops and the like comprising a united structure made of plastic material with two rocking bodies 1 separated by “V”-shaped channeling 2 and which are joined at the bottom by middle fins 3, the rocking bodies 1 having elastic hinge elements 14 and end portions 9 of elastic structure through which the wringer is anchored to the mouth of the mop bucket 10, the end portions 9 having spring elements 15 for recovering the rocking bodies 1. In addition the wringer 4 can have middle indentations 22 for allowing placement of a device for filtering cleaning water, which comprises a tray support 5. This device for filtering cleaning water is placed under the wringer 4. When water passes through the filtering device that is under the wringer 4, reaches the bucket already filtered with fewer dirt particles.

Abstract: A fastening device for folding boxes, the folding boxes including a bottom and four lateral walls coupled in jointed fashion to the edges of that bottom, two opposite walls having each fastening devices for ensuring the unfolding of the box, the device in general including a vertically displaceable central piece and some lateral bolts with horizontal displacement for fastening the lateral walls via their adjacent edges. The folding device includes elastic spring elements which link the central control piece with the pairs of bolts, at the same time, the spring elements, in the rest position, maintain the bolts in the engagement and fastening position of the bolts, while for the release position of the bolts the spring elements pull the bolts towards the release position against the resistance of the elastic elements.

Abstract: The inventive wringer for scrubbing buckets basically consists of two independent tilting parts of a wringer (4) which are pivotally coupled inside the space of a support (1) fixed to the bucket mouthpiece. Said independent parts (4) are pivotally coupled with parallel axes communicating with the end spaces (3) of the support (1) and are tiltable oppositely to the resistance of spring elements (5).

Abstract: A bucket is equipped with a rinsing basket in its open end and wheels in its bottom part. The bucket incorporates a pair of wheels going in the same direction placed before a cross-sectional plane that contains the center of gravity. The bottom part contains an ample posterior portion behind the pair of wheels and a narrow frontal portion that extends upwards and outwards and located before the wheels, configured in such a manner that when the bucket is in the at-rest or stationary position it is only supported by the posterior portion, while during the rinsing of the mop, when we press down the frontal part of the bucket with the mop, the bucket will oscillate slightly and will be able to travel if it is set to rest on the wheels by elevating the rear part that will leave the floor during this travelling stage.
