  • Patent number: 8522657
    Abstract: A slide-type cutting machine ensures safer operation of cutting wood or the like and can be housed in a compact state. A linear guide unit 3 includes a slide shaft 33 moving in a direction perpendicular to the moving direction of a cutting section 4, a first slide holder 31 for guiding the movement of the slide shaft 33, and a second slide holder 34 located at a lower end of the slide shaft 33 and for restricting the movement of the slide shaft 33 by abutting against the first slide holder 31. A linkage element 5 includes a first link 51 having one end connected to the cutting section 4 and the other end connected to the second slide holder 34, and a second link 52 having one end connected to the first slide holder 31 and the other end connected to the first link 51.

  • Publication number: 20100212467
    Abstract: A slide type cutting machine which conducts cutting work of a timber etc. more safely and can be stored compactly. A straight guide device (3) has a slide shaft (33) which moves in a direction orthogonal to the moving direction of a cutting part (4), a first slide holder (31) which guides movement of the slide shaft (33), and a second slide holder (34) which is provided at the lower end of the slide shaft (33) and abuts on the first slide holder (31) to control movement of the slide shaft (33). A linking means (5) has a first link (51) which has its one end connected with the cutting part (4) and the other end connected with the second slide holder (34), and a second link (52) which has its one end connected with the first slide holder (31) and the other end connected with the first link (51).

  • Patent number: 6735813
    Abstract: An air blower/vacuum includes a nozzle, a fan, and a main body. The main body is formed with a vacuum pathway and a blower pathway, located upstream and downstream, respectively, from the fan with respect to the flow of air. The main body is also formed with an attachment hole in fluid communication with both the vacuum pathway and the blower pathway. The attachment hole supports the nozzle rotatable between a vacuum mode orientation and a blower mode orientation. In the vacuum mode orientation, the pathway of the nozzle is in fluid communication with the vacuum pathway. In the blower mode orientation, the pathway of the nozzle is in fluid communication with the blower pathway.
