Description

  The present invention relates to a portable handheld power tool (e.g., a motor driven chain saw) having a receiving device.

  In general, a motor-driven chain saw has a main body portion in which a motor is mounted, and a saw bar located at the front end of the main body portion. A motor-driven chain saw with a handle on the top of the main body is generally called an upper handle chain saw. Its design is particularly suitable for advanced tree care performed by professional operators. Such advanced care of trees includes pruning and pruning of standing trees, so an operator often climbs the tree and uses an upper handle chain saw.

  The chain saw for use in such a situation is provided with a receiving device for connecting, for example, a rope or hook to the chain saw body so that the operator of the chain saw can easily perform the work. ing. One end of the rope can be connected to a safety belt worn by the operator. The rope can also be used to send a chain saw to an operator who has already climbed a tree to be pruned or otherwise processed. Such use of chain saws requires that the receiving device and the rope meet several conditions regarding wear resistance, weight and ease of use.

  U.S. Pat. No. 5,272,813 discloses an upper handle chain saw with a receiving device with a hole through which an operator can pass a rope. When a rope passes through a hole such as that described in U.S. Pat.No. 5,272,813, the rope will be very worn, and after a period of use, the wear may have a negative effect on the surface of the rope. is there.

The receiving device is easy to manufacture at low cost, requires minimal space when not in use, and minimizes wear and breakage of objects attached to the receiving device.

  It is also an object of the present invention to provide an upper handle chain saw having a receiving device that can simultaneously attach several external objects to the chain saw body.

  Thus, according to the first feature of the solution, at least one of these objects is achieved by the portable hand-held power tool of claim 1. This electric power tool has a receiving device arranged in the main body of the electric power tool. This receiving device is a handheld electric device that can carry a flexible elongate member (e.g. a rope) or a fixing device that is fixed to the elongate member or to an operator of a portable handheld power tool. It is configured to connect / disconnect with the tool. The receiving device has a receiving portion for receiving and guiding a flexible elongated member in a penetrating state. This receiving part extends substantially in a plane. Further, the receiving device has an attachment portion configured to connect the receiving device to a portable handheld power tool main body by a pivot device. Since the pivot device defines a pivot axis, the receiving part can move between a standby position in which the plane of the receiving part is substantially parallel to the pivot axis and an operating position. In the operating position, the receiving part can move about the pivot axis so that the plane of the receiving part is substantially perpendicular to the pivot axis.

  According to another embodiment of the invention, the second part of the attachment part extends in substantially the same plane as the receiving part. In this way, an optimal extension direction for the receiving part when in the operating position is realized.

  According to another embodiment of the invention, the pivot device comprises a clamping pin. The first part and the second part are separated by an intermediate part that defines a passage narrower than the diameter of the clamping pin for the purpose of holding the receiving device in the operating or standby position. Since the intermediate part is elastic, it is possible to move the receiving device into the pivot device between the operating position and the standby position of the receiving device.

  By providing such a narrow intermediate part, the receiving device is fixed in the operating or standby position and does not move unintentionally between the two positions. By providing elasticity in the middle part, the user can easily bring the receiving device between the two positions by a fitting movement.

FIG. 6 is a plan view of a hook receiving element according to an embodiment of the invention. FIG. 5 is a detailed view of the rear end of the main body of the upper handle chain saw shown in FIG. 1, showing a second embodiment of the receiving device.

  The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, since the invention can be implemented in many different forms, it should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this specification will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, like reference numbers indicate like elements.

  FIG. 1 shows a portion of a motor driven chain saw 1 having a body 2 to which a combustion engine (not shown) is attached. The main body 2 has a front end, a rear end 22, and a top surface, a bottom surface, and a side surface extending between the front end and the rear end 22. A chain guide bar 3 extends from the front end 21 of the main body 2 in the longitudinal direction of the chain saw 1. A saw chain (not shown) driven by the engine extends along a groove formed in the periphery of the chain guide bar 3.

  The chain saw shown in FIG. 1 is generally known as an upper handle type chain saw because the handle is attached to the top of the main body. The upper handle chain saw is such a design and is particularly suitable for the advanced care of trees performed by forest specialists. In general, an upper handle chain saw also has a handle on one side of the body.

  The rear end 22 of the main body 2 is configured to hold a receiving device 100 that can be used to connect a flexible elongated member such as a rope to the main body 2. The rope is typically attached to a safety belt worn by the chain saw operator. The receiving device 100 can also be used to connect the chain saw directly with a safety belt. In that case, for example, a snap hook attached to a safety belt is connected to the receiving device 100.

  A part of the rear end 22 of the chain saw body 2 is shown in FIG. 2a. The receiving device 100 according to one embodiment of the present invention is attached to the rear end 22. As can be seen from FIG. 2 a, a recess 23 is formed in the surface 22 a of the rear end 22. The shape of the recess 23 is preferably complementary to the shape of the receiving device 100 so that the operator of the chain saw can retract the receiving device 100 into the recess 23 when they do not wish to use it.

  The receiving device 100 of the present invention has one or several elements. According to the first embodiment of the invention, the receiving device 100 is a flexible member connecting element 115. This will be referred to as the rope loop 115 in the future. One embodiment of the rope loop 115 is shown in FIGS. 3a-3c.

  The rope loop 115 is preferably composed of a single piece of material 15 (eg, a member 15 made of spring wire) and is formed by bending the piece of material 15 into a receiving portion 110 and a mounting portion 120. The

  3a to 3c are views of the rope loop 115 as seen from different directions, in which the X-Y-Z axes are incorporated.

  The receiving part 110 is configured to receive a flexible elongated member such as a rope, whereas the purpose of the attachment part 120 is to connect the rope loop 115 to the chain saw body 2. . As will be described later, the mounting portion 120 has a standby position hole 121 and an operating position hole 122.

  An unbent spring wire member 15 is shown in FIG. 3d. This member 15 is suitable for bending into the shape of a rope loop 115 according to the invention. The spring wire member 15 includes a first outer leg section 15a, a first inner leg section 15b, a central section 15c, a second inner leg section 15d, and a second outer leg section. 15e.

  To form the receiving portion 110 of the rope loop 115, the central section 15c of the spring wire member 15 is bent into a substantially circular loop. According to one embodiment of the receiving part 110, the diameter of this loop is about 20-30 mm. Since the two outer end portions of the central section 15c intersect with each other at the first connection point 124, the receiving portion 110 is spirally wound once. The receiving part 110 is substantially in the XY plane P as shown in FIGS. 3a to 3c.

  The two outer ends of the central section 15c of the spring wire member 15 continue to the inner leg sections 15b and 15d adjacent to the first connection point. The inner leg sections 15b, 15d and the outer leg sections 15a, 15e are bent to form the attachment 120 for the rope loop 115.

  As can best be seen from FIG. 3c, the first part 121 of the mounting part 120 bends the inner leg sections 15b and 15d of the spring wire member 15 into two opposing C-shaped sections 121a and 121b. Formed by. As a result, a hole extending in the YZ plane is formed. The outer ends of the inner leg sections 15b and 15d approach each other in a transition region 123 that defines the boundary between the first portion 121 of the mounting portion 120 and the second portion 122 of the mounting portion 120.

  The second portion 122 of the mounting portion 120 is formed by bending the outer leg sections 15a, 15e of the spring wire member 15 into holes that extend in substantially the same plane P as the receiving portion 110. . The outer leg sections 15a, 15e are bent so that both have substantially the same radius of curvature as that of the C-shaped sections 121a and 121b.

  In order to ensure that the second portion 122 has a reasonable tensile strength, the outer leg sections 15a, 15e of the spring wire member 15 are formed with the second portion 122 as shown in FIG. Overlapping when forming.

  The receiving device 100 is connected to the chain saw body 2 using a pivot device 4 with a clamping pin 41. In the embodiment shown in the accompanying drawings, the pin 41 is inserted into a substantially horizontal groove 24 provided at the rear end 22 of the chain saw body 2. Since the groove 24 is positioned adjacent to and in front of the rear end surface 22a, the extending direction of the groove 24 is substantially parallel to a plane in which the rear end surface 22a actually extends. As can be seen from FIG. 2 b, the groove 24 has an inlet 24 a for inserting the clamping pin 41. Since the groove 24 is at least partially covered by the rear end face 22a, a tube-shaped tunnel is defined and the clamping pin 41 is captured therein. One or several openings through which the inside of the groove 24 can be seen are formed at positions where the receiving device 100 will be connected to the pin 41 at the rear end face 22a.

  In the embodiment shown in the accompanying drawings, the clamping pin 41 is a tapping screw 41 having a hexagonal head or a tapping bolt 41 having a hexagonal head. The screw or bolt 41 has a non-tapered shaft having a threaded portion at the end near the head. Preferably, the remainder of the shaft is not threaded. The screw thread cut on the wall surface of the groove 24 like a screw is turned into the groove. The operator can turn the screw 41 into the groove 24 using, for example, a hexagonal tool.

  The position of the groove is preferably selected so that the chain saw bar extends in a direction convenient for the operator when the chain saw is suspended from the receiving device.

  The pivot device defines a pivot axis PA, and the rope loop 115 is adapted to rotate about the pivot axis PA.

  When the rope loop 115 is in the standby position, the first portion 121 of the attachment 120 tightens the pin 41 of the pivot device 4. Henceforth, the first portion 121 will be referred to as a standby position mounting hole 121.

  When the rope loop 115 is in the operating position, the second part 122 of the mounting part 120 clamps the pin 41 of the pivot device 4. Henceforth, the second portion 122 will be referred to as an operating position mounting hole 122. The radius of curvature of the two mounting holes 121, 122 is selected such that the shape of each mounting hole 121, 122 is substantially complementary to the diameter of the mounting pin 41.

  The transition region 123 defines a passage that is narrower than the diameter of the clamping pin 41.

  When the operator of the chain saw does not want to use the rope loop 115, the rope loop 115 is set to the standby position. At that time, the rope loop is retracted into the recess 23. The mounting hole 121 for the standby position tightens the clamping pin 41, and the plane P on which the receiving portion 110 is widened is substantially the same as the plane on which the surface 22a of the rear end 22 in which the concave portion 23 is formed using a part is widened. Parallel. The Y axis of the rope loop extends in the vertical direction of the chain saw body 2, and the X axis of the rope loop 115 extends in the same direction as the pivot axis PA of the pivot device 4. The rope loop 115 in the standby position is shown in FIG. 2b.

  To move the rope loop to the operating position, the operator grasps the receiving part 110 and rotates the rope loop 115 around the Y axis while rotating around the pivot axis PA defined by the clamping pin 41. . The shape of the recess 23 provided in the chain saw body 2 is preferably suitable for guiding the movement of the rope loop when the rope loop is moved from the standby position to the operating position. When the receiving part 110 moves rearward with respect to the chain saw main body part, that is, away from the main body part 2, the operating position mounting hole 122 hits the bottom surface of the recess 23. The movement of the rope loop 115 is guided by the operator's pulling force, the shape of the recess 23 and the shape of the mounting portion 120. As a result, the mounting hole 121 for the standby position stops tightening the tightening pin, and the rope The loop enters the position where the operating position mounting hole 122 tightens the clamping pin 41 instead. This is possible even if the distance between the two leg sections defining the mounting part 120 in the transition region 123 is smaller than the diameter of the clamping pin 41. This is because the transition region 123 has elasticity. When the fitting movement occurs and the clamping pin 41 passes through the transition region 123, the transition region 123 is elastic and returns to its original shape, so that the clamping pin 41 is captured in the operating position mounting hole 122.

  The rope loop 115 is in the operating position when the operating position mounting hole 122 of the mounting portion 120 is tightening the tightening pin 41. When the rope loop 115 is in the operating position, the plane P formed by the receiving part 110 is substantially vertical and perpendicular to the pivot axis PA. The rope loop in the operating position is shown in Figure 2a. Since the operating position mounting hole 122 fastens the fastening pin 41, when the rope loop in the operating position is rotated around the pivot axis PA, no part of the rope loop 115 hits the bottom surface of the recess 23. As a result, the position of the receiving part 110 relative to the chain saw body 2 is flexible when the rope loop 115 is in the operating position. The rope loop can be rotated up and down around the pivot axis PA until the receiving part 110 hits the chain saw body part 2.

  To move the rope loop 115 from the operating position to the standby position, the operator rotates the receiving part 110 upward around the pivot axis PA until a part of the receiving part 110 hits the main body part 2. Next, the operator presses a portion of the receiving unit 110 that is away from the main body 2 so that this portion approaches the main body 2. Then, the rope loop 115 rotates around the Y axis. Further, the rope loop 115 is moved downward to force the clamping pin 41 into the elastic transition region 123 and further into the standby position mounting hole 121. When the clamping pin 41 enters the standby position mounting hole 121, the transition region 123 returns to its original shape, and the clamping pin 41 is captured in the standby position mounting hole 121.

  As described above, it is possible to adjust the tensile strength of the operation position mounting hole 122 by selecting the length of the overlapping portion. The amount of overlap is selected to withstand the weight of hanging the chain saw 1, for example to maintain its shape when the operating position mounting hole 122 is subjected to several kg of pulling force, and more The operating position mounting hole 122 can be selected to break when subjected to a fairly large pulling force (for example, the force generated when an operator connected to a lifeline attached to the rope loop 115 falls).

  According to one embodiment of the invention, the receiving device 100 comprises a hook receiving element 130 for connecting the chain saw 1 to a safety belt worn by the operator of the chain saw. A hook (eg, a snap hook) connected to the operator's safety belt can be attached to the hook receiving element 130. From now on, the hook receiving element 130 will be referred to as a hook loop 130. When a chain saw operator needs to move from one position to another on a tree, he or she attaches the chain saw to the safety belt with snap hooks and hook loops 130. It can be hung from the safety belt in a free state. The operator can then freely use both hands to climb the tree.

  A receiving device 100 having a rope loop 115 and a hook loop 130 is shown in FIG. As can be seen from this figure, the hook loop 130 is attached to the chain saw body 2 by the same pivot device 4 as the rope loop 115.

  FIG. 4 is a plan view of a hook and loop 130 according to one embodiment of the present invention.

  The hook loop 130 as shown in FIG. 4 is formed by bending a rod-shaped piece of material into the required shape. According to one embodiment of the present invention, the hook loop 130 is formed from an aluminum rod having a diameter of 6 mm.

  The ends 132 and 133 of the hook loop 130 are compressed and flattened, and through holes for passing the fastening pins 41 are provided in the respective ends 132 and 133. A curved portion 131 extends between the end portions 132 and 133.

  As can be seen from FIG. 4, the curved portion 131 of the hook and loop 130 may be asymmetric. A preferred embodiment of the curved portion 131 has a distorted U shape having a base portion 131a and two leg portions 131b and 131c.

  The longitudinal direction L of the hook and loop extends from the end portions 132 and 133 toward the base portion 131a of the central portion 131.

  The first leg 131b is substantially parallel to the longitudinal direction L of the hook loop 130, while the inclined leg 131c extends at an angle A with respect to the longitudinal direction L of the hook loop 130. .

  The hook loop 130 is connected to the chain saw body so that the plane in which the central portion 131 extends is substantially parallel to the horizontal plane of the chain saw 1. When the chain saw is attached to the operator's safety belt with a snap hook, the chain saw 1 is suspended in an appropriate direction because it extends in such a direction. It would be even better if the longitudinal direction of the hook and loop extends slightly upward relative to the horizontal surface of the chain saw, as shown in FIGS. In this way, the direction in which the chain saw hangs will be even more favorable for the operator.

  The hook loop 130 is preferably designed so as not to affect the mobility of the rope loop 115 as much as possible. In the embodiment shown in FIG. 5, the movement of the rope loop 115 is not affected by the hook loop 130 at all. Because these two loops are juxtaposed with each other. The rope loop 115 is attached to the clamping pin next to the hook loop first end 132.

  According to another embodiment of the invention, the receiving device is designed such that the rope loop is attached to the clamping pin at a position between the two ends 132 and 133 of the hook loop. In order to minimize the effect of the hook loop on the rope loop mobility, the hook loop according to such an embodiment spreads when the hook loop is attached to the chain saw body 2. It is preferable to bend so that the flat surface is located below the pivot axis PA.

  The distance between the two legs 131b and 131c at the widest point of the hook and loop 130 can be, for example, about 20-30 mm. In the longitudinal direction, the distance between the centers of the through holes of the end portions 132 and 133 and the base portion 131a of the curved portion 131 can be about 30 to 35 mm, for example. The distance between the ends can be, for example, about 15-25 mm.

  When hook-and-loop 130 is connected to the operator's safety belt using a spring clip-type hook with a spring-loaded gate that keeps the clip closed, an inclined leg as shown in Figure 4 A hook loop 130 having 131c is particularly advantageous. This is because the slanted leg 131c helps the operator open the spring-loaded gate of the spring clip when the operator wants to remove the chain saw from the safety belt. The operator holds the chain saw with one hand, rotates it slightly while lifting it upward, pushes the slanted leg 131c of the hook and loop toward the spring-loaded gate, opens the gate, and opens the chain saw. release. The operator does not need to use his free hand to open the spring clip. Instead, the hand can be used to grab the tree that the operator is climbing.

  The slanted leg 131c extends at an angle A with respect to the longitudinal direction L of the hook and loop 130, so that the chain saw operator can only rotate the chain saw away from the spring clip. Good. If this leg 131c was parallel to the longitudinal direction L of the hook and loop 130, the operator would have had to rotate the chain saw more. As a result, the operation of moving the chain saw away from the spring clip is more comfortable for the chain saw operator, thanks to the inclined extension direction of the inclined leg 131c.

  According to the embodiment shown in FIG. 4, the magnitude of the angle A is about 30 °, but other angles are possible.

  Hook loops can be supplied as optional equipment. Therefore, if the operator wants to use the hook and loop, it can be attached to the pivot device and removed when the operator uses the chain saw in situations where the hook and loop are not needed.

  In the drawings and specification, preferred embodiments and examples of the invention have been disclosed. Although special terminology is used, these terms are general and illustrative only and are not intended to limit the invention. The scope of the invention is set forth in the following claims.
