Publication number: 20190029406Abstract: A system and method for manually cleaning an environment of a substance with an oil content. A hand tool includes a handle part and an attached brush element with fitted bristles. A cleaning tool includes a scraper with scraper elements to clean the hand tool brush element. Some of bristles of the hand tool are arranged in bristle bunches in one or more lines. The length of the bristle bunches is arranged to differ between the lines. In the brush element some of the lines of the bristle bunches are at a distance from each other. The scraper elements of the scraper of the cleaning tool and the lines of bristle bunches of the brush element of the hand tool are arranged relative to each other to scrape the substance with an oil content from between the lines of bristle bunches by the scraper elements.Type: ApplicationFiled: February 10, 2017Publication date: January 31, 2019Applicant: SAJAKORPI OYInventors: Kimmo SAJAKORPI, Timo HIRSIVUORI

Patent number: 7802339Abstract: Side brushes adapted to be mounted on a sweeping machine and operative as a brush about a rotation axis are disclose herein. The side brushes include a base element and a bristle segment. According to one embodiment, the base element has at least one outer edge and an elongate channel extending inwardly from a respective outer edge. The bristle segment has a plurality of bristles and a frame member. The frame member has a configuration complementary to a configuration of the elongate channel such that interaction between the frame member and the base element adjacent the elongate channel couples the bristle segment to the base element. Each bristle has a top end, and all of the bristle top ends are fused together to define the frame member.Type: GrantFiled: February 15, 2007Date of Patent: September 28, 2010Assignee: Sajakorpi OyInventors: Reijo Kuivikko, Kimmo Sajakorpi
