摘要： A chainsaw comprises a main body (1), a motor housed within the main body, the motor being drivably connected to a sprocket drive shaft (6), and a guide bar/saw chain assembly (4). The assembly (4) comprises a guide bar (7, 8), a saw chain (12) and a sprocket drive wheel (5). The guide bar has first and second guide bar portions (7, 8) telescopically connected together, and the sprocket drive wheel (5) is associated with the second guide bar portion (8). The saw chain (12) is in drivable engagement with the sprocket drive wheel (5) and passes around the peripheries of the first and second guide bar portions (7, 8). The sprocket drive wheel (5) is in drivable engagement with the sprocket drive shaft (6). The assembly (4) is movable between a first, non-operative position in which the first and second guide bar portions (7, 8) are positioned so that the saw chain (12) is not tensioned, and a second, operative position in which the first and second guide bar portions are positioned so as to tension the saw chain.

摘要： A guide bar (1) for chain saws (50) includes a first guide plate (10), a second guide plate (30) and a spacer plate (20) which is sandwiched between the first (10) and second guide plates (30). Each of the first (10) and second guide plates (30) has a plurality of protrusions (11,31) extending from an outer side thereof and recesses (111,311) defined in an inner side thereof, A groove (21) is defined along an outer periphery of the spacer plate (20) and located between the first (10) and second guide plates (30) so as to receive the chain (40). The protrusions (11,31) and recesses (111,311) reinforce the structural strength of the guide bar (1) and reduce the friction between the guide bar (1) and the object to be cut.

摘要： The claimed invention relates to a device in a guide bar (10) for a chain saw. The guide bar (10) comprises at least two layers (11, 12, 13) that are bounded by an adhesive material. To ensure that the layer of adhesive material gets the optimal thickness is one of the surfaces of the layers that will be bounded to each other provided with several protruding parts (17). The protruding parts (17) will generate a slot, with the same width as the height of the protruding parts, for the adhesive material when the layers are put together. This is important to ensure maximum strength in the bounding as well as a constant width of a groove (14) for the saw chain.

摘要： This disclosure relates to a guide bar (1) for a chain saw, wherein easily formed multiple through-holes (2) are provided in a guide bar (1) for the purpose of reducing the weight of the guide bar (1). A synthetic resin material (7) fills the through-holes (2) and is prevented from falling out of the guide bar (1) by locking parts (5) at the margins of the holes. In the process of making the guide bar (1), after multiple through-holes 2 are provided in a guide bar (1), the areas around the through-holes 2 are compressed so that they undergo plastic deformation and form the locking parts 5. Then the synthetic resin material 7 is injected into these through-holes 2 and allowed to harden so that it becomes an integrated construction with the guide bar 1, and the synthetic resin material 7 is securely locked in place by the locking parts.

摘要： A chain saw bar (34, 16) has an elongated shape, a saw chain guideway around substantially the length of the perimeter thereof and a matching saw chain sprocket (18) in the nose (16) thereof. There is a region (52, 54) of calculated variation in strength in the interior of the bar at a location removed from the sprocket (18), so that if the bar is subjected to an excessive bending force in use, the bar will tend to become bent at about the region of variation in strength.

摘要： A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around 5 which a chain (210) is rotatable. The guide bar (120) includes first and second side plates (400, 410), a core (420) and a tension indicator (240). The first and second side plates (400, 410) each face other and extend away from a housing (110) to a nose. The core (420) is disposed between the first side plate (400) and the second side plate (410). The tension indicator (240) is provided at the core (420) and is visible at at least one of the first side plate 10 (400) or the second side plate (410). The tension indicator (240) is configured to indicate a chain tension based on a position of the guide bar (120).
