Abstract: A cleaning wiper blade comprises a hand grip part and an elastic part. The elastic part comprises a polyurethane. The polyurethane comprises a reactant of a composition including an isocyanate compound which includes diisocyanate and polyfunctional isocyanate, and an alcohol which includes polyfunctional alcohol. The diisocyanate has an aromatic ring in a molecule. When a molecule of the polyurethane is ionized with a mass spectrometer of a direct sample injection system, then obtained M1, M2 and M3 satisfy the is 0.013 to 0.300, and a concentration of the polyfunctional alcohol in the polyurethane is 0.12 mmol/g to 0.65 mmol/g.

Abstract: Scrapers for removing adhered material from surfaces employ continuous and discontinuous material removal edges to remove different types of material. Continuous and sometimes discontinuous material removal edges are constructed and arranged to conform to the curvature of a surface from which material is to be removed, when a user forces the scraper against the surface. Some scrapers include multiple material removal edges designed to simultaneously contact the surface. The use of multiple points of contact combined with locations of handles provide stable designs that reduce hand and wrist strain.

Abstract: A pole section for temporary assembly with similar pole sections into an elongate pole assembly whereby a user can perform work on a remote worksite elevated by up to 20 m above the user. Each pole section includes a male end and a female end, having a complementary taper to slide into or around the other of a male or female end and form a fluid tight joint with a stiffness similar to or greater than the overall stiffness of the pole. The ends of each pole section include one of first and second complementary coupling parts. The coupling parts cooperate to prevent the pole sections moving relatively towards each other under the weight of overlying pole sections in use to prevent the pole sections jamming A resiliently deformable locking structure is provided in a coupling part by a ring spring.

Abstract: A much improved universal fitting squeegee holster where the optimal size of the void in an insertion point, the optimal distance between insertion points and a drop in height across the insertion points creates a comfortable and practical holster. A universal squeegee holster in which the angle of placement and the shape of retention mechanism makes the wearer comfortable and capable of faster insertion and retrieval of squeegees. When holstered the distance between handles 4 creates space for squeegees of varying sizes to be quickly extracted. The distance between the wearer and insertion point 11 of the squeegee is optimised for easy extraction.
A universal holster for squeegees comprising a holster body made of a substantially rigid or pliable material and configured for securely receiving a squeegee. Holster body comprising a holster cavity configured for securely accommodating and partially embracing portions of the squeegee 11. The front panel of holster has one or two insertion points. The insertion points are for holding and extracting the squeegee. The top of the back layer of the holster is configured for attachment 2 to be secured to a belt on the wearers waist.

Abstract: An ice scraper comprising a handle and a scraper head connected to the handle. The scraper head includes a proximal end, a distal end having a scraping edge, a scraping side, a chipping side, and at least three chipping teeth for chipping ice, hard snow, or frost from a curved surface. The chipping teeth extend outwardly from the chipping side. Each chipping tooth has a contact edge. At least one of the contact edges is offset forward or rearward of contact edges of two of the other chipping teeth so that at least one point of each contact edge can simultaneously contact the curved surface regardless of the scraper's position relative to the curved surface and regardless of a direction of the scraper.

Abstract: A portable electric heating ice scraper with an elongated housing, configured to remove ice from a windshield. The housing includes: a front housing portion including a front housing end and a scraper disposed at the front housing end, and a rear housing portion including a handle and a rear housing end. An electric-powered fan that generates an airflow in a direction of the scraper and at least one electric-powered heating element configured to heat the airflow are disposed in the housing. The front housing portion and the rear housing portion approximately extend on a plane in a longitudinal direction of the housing or the front housing portion is curved at an angle not greater than 35° relative to the rear housing portion in the longitudinal direction of the housing.

Abstract: A cleaning implement includes an elongated, arcuate shaft having a handle at a proximal end and a cleaning head at a distal end. The cleaning head includes a plurality of juxtaposed, removable attachments, such as a sponge, a scrubbing brush and one or more wiper blades. The shaft is constructed with a resilient but slightly pliable material so that a user can simultaneously force the sponge, brush and blades against a windshield by applying a predetermined amount of force to the handle.

Abstract: An ice scraper blade and/or brush mounted to a handle which has an anatomically designed grip. Attached to the handle is a cover to protect the user's hand from snow, ice, water, and cold. The cover has a sleeve with a first side made of waterproof fabric and a second side which is insulated with a suitable thermo-insulating fabric. In a first position of the cover, the first side of the sleeve is exposed to the outside for protecting the user's hand against the elements. In a second position of the cover, the sleeve is reversed so that the first side of the sleeve is on the inside, for enclosing ice, water and snow that may be adhered to the ice scraper blade and/or brush. The cover is also provided with a fastening arrangement that is placed at the second end of the sleeve, which prevents entering of snow and ice into the cover in the first position, and which contains the ice, water and snow inside the cover in the second position.

Abstract: A window wiper is substantially tee-shaped, having a wiper head and a wiper handle, the wiper head being bent with respect to the wiper handle and the wiper head and the wiper handle delimiting a bending angle. The wiper head and the wiper handle may be connected to each other by a flexible joint, the wiper head and the wiper handle being movable from an initial bending angle to a maximum final bending angle against the spring force of the flexible joint.
