| PROBLEM TO BE SOLVED: To hold a bar in the state of applying tension to chains during the work of clamping the bar against a chain saw housing. SOLUTION: A guide bar mounted on the studs 22, 24 of a chain saw has a slender bar main body having an axially extending cavity. The rear end portion 50 of a shaft 42 slidable within the cavity is engaged with the studs and has backwardly projecting fingers 56 having an inner edge and an outer edge 59. When the shaft having a crack 52 in its longitudinal direction is moved backward in such a way as to be pressed against the studs, the inner edge is engaged with the studs to open the crack and to widen the fingers and the bar main body is moved relatively forward to apply tension to chains therearound. When the fingers are widened, the outer edge tapered is engaged with the edge 36t of the tapered cavity whereby the relative positions of the studs, shaft, and bar main body are fixed.

| PROBLEM TO BE SOLVED: To provide a saw chain stretching device for a chain saw which is low-priced and can be easily operated without a hindrance by a chain guide plate and can be simply adjusted to the change in an operating position for an operator through his adjustment procedures. SOLUTION: This saw chain stretching device 1 is held between a side case 2 and a body case 22 and adjusts the position of a chain guide plate 4 projecting from a gap between both cases 2, 22. In addition, the device 1 is equipped with a threaded bar member 9 with a head part 10 formed on one of the ends and a pin member 16 which moves the position of the chain guide plate 4 with the body case 22 through moving in the axial direction of the pin member 16 by rotation of the threaded member 9. On the threaded bar member 9, a driven bevel gear 23 is fixed to the end part opposite to the head part 10, in the axial direction O-0, and a drive bevel gear 23 with a shaft part 24 supported pivotally, in a freely rotating manner, on the side case 2, is engaged with the driven bevel gear 23. In addition, the rotary operating part 24b of the shaft part 24a is exposed to the outside of the side case 2. COPYRIGHT: (C)1998,JPO | ||||||

| PROBLEM TO BE SOLVED: To realize the proper adjustment of the tension of a chain at all times by a method wherein a guide bar is biased in the tensioning direction of the chain by mounting a plate spring on a main body. SOLUTION: A plate spring 13 consists of a bottom plate part 13b, at both the sides of which squarely projecting engaging projecting piece parts are provided, a vertical plate part 13c, which nearly vertically rises from the bottom plate part by being bent, and a curved plate part 13d, which bends from the upper part of the vertical plate part in a U-like fashion to the bottom plate part 13b. On the rear surface side of a gear housing 2, an engaging recessed part 2d, which locates lower than its rear surface by one step, is formed so as to serve as the locking of the plate spring 13. Further, a pressing projecting part 3a, which is fitted to an engaging recessed part 2d so as to fix the plate spring 13 to a chain saw main body 4. The bottom plate part 13b side in the vertical plate part 13c of the plate spring 13 abuts against the side surface of a sprocket 7 side, resulting in projecting its curved plate part 13d to a guide bar 8 side. The outer peripheral surface of the curved plate part 13d abuts against the near central portion of the rear end of the guide bar 8 so as to biase the guide bar 8 in the tensioning direction of a chain 9 by means of the elastic force of the plate spring 13 at all times.

| PURPOSE: To provide an easier, quicker and more effective procedure for producing openings in concrete walls without corners by constituting a carriage having an elongated chain bar positioned perpendicular to a wall and being within a plane defined by a cutting line, a cutting chain being movable along the chain bar, and means for driving the cutting chain along the chain bar, a track and the carriage extending to only one side of the plane in a first operative condition of a chain saw assembly. CONSTITUTION: A chain saw comprises a carriage 18, an elongated chain bar 16 having means for driving a cutting chain around the bar and a chain around the bar. The carriage 18 contains means for driving the cutting chain around the chain bar and means for driving the carriage 18 along a track structure 6. The chain saw 12 is positioned along the track structure 6 in the same manner as a circular saw 2 is positioned along the track structure 6. The elongated chain bar 16 of the chain saw 12 is inserted into a kerf 8. By driving the chain saw upward, the kerf extends to a cutting line 11 at all points through the thickness of the wall but does not extend beyond the cutting line 11, thereby forming a square corner cut.

| The invention relates to a work device with a guide rail (4) on which a chain (5) is driven in a circulating manner. The work device has a clamping device (15) for the chain (5). The clamping device (15) has a clamping element (16) which acts on en the guide rail (4) in the direction (19) of the longitudinal central axis (18) of the guide rail (4). The clamping device (15) has a rotatably mounted adjusting element (17) which is connected to the clamping element (16) via a threaded connection (20). A rotation of the adjusting element (17) about its rotational axis (21) causes a movement of the clamping element (16) in the direction (19) of the longitudinal central axis (18) of the guide rail (4). The outer circumference of the adjusting element (17) has a threaded portion (22) with at least one turn (23), said threaded portion being provided for engaging with at least one threaded portion (24) of the clamping element (16). The adjusting element (17) has an actuating contour (39) so that a user can rotate the adjusting element (17), said actuating contour comprising at least one depression. The largest spacing (b) between the threaded portion (22) of the adjusting element (17) and the rotational axis (21) is at least as large as the largest spacing (a) between the actuating contour (39) and the rotational axis (21). | ||||||

| The present disclosure relates to a chain saw of a wood handling device and to controlling the guide bar in it. The guide bar is attached to a turning frame rotatably arranged to a frame of the chain saw through a fastening arrangement. The fastening arrangement of the guide bar and the turning frame are joined by at least one guide for controlling the guide bar during movement along its longitudinal axis. The guide includes opposite slide guides with opposite sliding and mating surfaces that form a form-locking joint joining the fastening arrangement and turning frame together. This type of separate slide guide arranged in the chain saw is movable in at least one direction differing from the direction of travel allowed by the guide, which makes it possible to modify clearance between the sliding surface and mating surface. | ||||||

| A quick tensioning system applicable to handheld chainsaws is provided wherein, during chain re-tensioning, the chain guiding bar remains firmly anchored to the bar holder and guiding means are provided to retract the motorized driving sprocket versus said guiding bar. The system includes a guide interposed between a stationary bar holding body and a motor body. This allows a linear or a rotation relative movement between the sliding driving sprocket and the stationary guiding bar. A drive is provided by means of a screw that an operator can easily operate via a knob conveniently mounted nearby the chainsaw handle. | ||||||

| A chain saw includes a housing, a sprocket wheel which is provided in the housing for driving a saw chain, and a chain guide for guiding the movement of the saw chain. The chain guide extends out longitudinally from the housing and is movable longitudinally relative to the housing. The chain saw includes a chain tensioning device. The chain tensioning device comprises a driven member arranged on the chain guide and a driving member which drives the driven member to move the chain guide longitudinally and a rotating device rotating the driving member. A stepless clutch device is arranged between the rotating device and the driving member. The chain tensioning device presses the chain guide while it tensioning the saw chain. Thus it prevents effectively the chain guide from loosing after the saw chain is tensioned. The operation of the chain tensioning device is labor-saving. The chain tensioning device has a stable structure and it is hard to be worn. | ||||||
