  • Patent number: 11104224
    Abstract: A closure cap for an operating medium tank is provided with a closure device projecting into a fill socket of the operating medium tank. The closure device has a first cap element, a second cap element, and a sealing ring arranged between the first and second cap elements. A lifting assembly axially moves by an axial travel the first and second cap elements relative to each other for opening and closing the fill socket. The lifting assembly has a pressure member acting axially on one of the first and second cap elements. A grip member is provided that is rotatable about a hub and actuates the lifting assembly. A cover disk covering at least partially the fill socket relative to an exterior is connected fixedly to the pressure member of the lifting assembly. The cover disk rotates, together with the pressure member, about the hub.

  • Patent number: 10814518
    Abstract: A chainsaw having a drive motor. The chainsaw has a fixed part and a movable part. The guide bar is retained on the fixed part in a manner braced between the fixed part and a tensioning element. The movable part is shiftable in a longitudinal direction with respect to the fixed part in order to tension the saw chain with the tensioning element released. The chainsaw has a stop face and a tensioning face. At least one additional contact face that is firmly connected to the fixed part in the longitudinal direction and at least one additional contact face that is firmly connected to the movable part in the longitudinal direction are arranged between the stop face and the tensioning face. All the contact faces lie one after another in the flux of force from the tensioning element to the fixed part.

  • Patent number: 10307930
    Abstract: A guide bar for a saw chain includes an elongate, flat base body made of a basic material. The base body extends along a longitudinal center axis and, in order to guide a saw chain, has a running surface formed on an outer periphery thereof and a guide groove formed in the outer periphery of the base body. The guide groove has a groove base. A direction-reversing section for the saw chain is provided at one end of the base body. The direction-reversing section includes at least one add-on component having a running surface made of more wear-resistant material than the basic material of the base body. The add-on component is secured to the base body of the guide bar by at least one weld seam. The weld seam extends between the add-on component and the base body and is located spatially beneath the groove base.

  • Patent number: 10293445
    Abstract: A handheld work apparatus has an electric motor and a voltage source for operating the motor. A manual actuation element provided on a handle of the apparatus is operated by a user and is provided for activating the motor. The actuation element is connected to a control unit which controls the energy supply from the source to the motor as a function of an operating signal of the actuation element. If the control unit is in a blocking state, the energy supply to the motor is blocked independently of the operating signal of the actuation element. After receiving a control signal, the control unit switches from the blocking state to a standby state to release an energy supply to the motor. The control signal is derived from a combination of an actuation stroke and an actuation time (?TB) of the actuation element. A method for activating the apparatus is also disclosed.

  • Patent number: 9732795
    Abstract: A cutting assembly of a chainsaw includes a saw chain and a guide bar (4) for guiding the saw chain (3) along a peripheral edge (5) of the guide bar. The saw chain (3) has drive links (6) having drive bases (7) which with their side surfaces (8, 8?) are slidingly guided between the side walls (9) of a guide groove (10) of the guide bar (4) with the formation of a friction pairing. Lubricant pockets (11) are formed in the side surface (8). The lubricant pockets (11) are only open toward the corresponding side wall (9) of the guide groove (10) and are otherwise closed. Offside the lubricant pockets (11), the side surface (8) has a flat sliding surface (12) which slides on the side wall (9) of the guide groove (10). The lubricant pocket (11) has a mean diameter and a maximum depth. The ratio of the mean diameter to the maximum depth lies in a range of 5.0 up to and including 25.0.

  • Patent number: 9573294
    Abstract: A chain for a work implement has lateral connecting members connected to central driving members via studs. The stud has two lateral portions spaced apart from one another by a collar. A driving member is mounted pivotably on the collar. At the collar the stud has a surface layer harder than the base material. For a high chain service life, the stud has a diffusion layer above a surface layer above the base material. To produce the stud, the stud is provided with a diffusion layer at least at the collar, and a surface region of the collar is hardened, such that a surface layer is formed between the diffusion layer and the base material of the stud. For a method for producing a driving member, the driving member is provided with a diffusion layer at least at a circumferential surface of a hole and the driving member is hardened.

  • Publication number: 20150183124
    Abstract: A cutter tooth has a base member with rivet openings spaced at a rivet spacing. A cutting element is attached by brazing to the base member at the upper edge of the base member. A depth limiter is provided on the base member in front of the cutting element. A chip recess is formed between depth limiter and cutting element. The depth limiter has an upright edge delimiting the chip recess. A forward contour of the lateral section of the cutting element and an inner contour of the chip recess define a corner point within the chip recess. The corner point is positioned at a first spacing relative to the upright edge of the depth limiter. The rivet spacing is divided by a perpendicular center plane positioned at a second spacing relative to the upright edge of the depth limiter. The first spacing is smaller than the second spacing.
