Description

  The present invention relates to a high branch cutting shear suitable for pruning branches at high places and picking fruits.

  As a tool suitable for pruning branches at high places and picking fruits, a pipe member fitted in a stretchable manner is provided, and a tool having a movable blade and a fixed blade is provided at the tip of the pipe member, and a pipe is provided. Various types of high branch cutting rods have been proposed in which an operating lever is provided at the base end of the member, and an operating means capable of opening and closing the movable blade by operating the operating lever is incorporated in the pipe member.

  However, as in the inventions described in Patent Documents 1 and 2, the high branch cutting rod configured to grip the movable lever toward the fixed lever side or the pipe member side and rotate the movable blade to the closed position is movable with the gripping force. In relation to operating the blade, a relatively thin branch can be easily cut. However, when a relatively thick branch having a diameter exceeding 5 mm is cut, a large force is required. In addition, since the movable lever is constantly urged to the open side by the return spring, it is necessary to grip the movable lever against the urging force of the return spring when operating to the closed posture. For this reason, there was a problem that women and elderly people with weak grip cannot smoothly cut branches. In addition, if a large number of branches are cut, there is a problem that even an adult male cannot get power in his hand.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a high branch cutter that can be easily operated by a woman with weak grip and the elderly, and that can reduce the fatigue of an operator.

  A high branch cutting rod according to the present invention is a high branch cutting rod comprising a pipe member, a jig provided at a tip side portion of the pipe member, and an operation means for opening and closing a blade of the jig. The operation means includes a handle support member provided at a proximal end portion of the pipe member, a handle member rotatably supported by the handle support member, and a transmission for transmitting an operation force of the handle member to a fixture. The handle member includes a grip portion that can be gripped by hand, a pivot portion with respect to the handle support member, and a connecting portion with respect to the transmission means in order from the distal end side. The handle member is rotatably supported by the support member over a closed position extending along the pipe member toward the distal end side of the pipe member and an open position extending laterally or obliquely toward the pipe member. By gripping the grip part with one hand, grasping the pipe member with the other hand, and operating the handle member to a closed position along the pipe member, the blade of the fixture can be operated in a closed state. It has been done.

  In this high branch cutting bar, the handle member is rotated between the open position and the closed position, whereby the cutting tool of the bar tool is opened / closed via the transmission means to cut the branch. At this time, in the closed position, the handle member is disposed so as to extend toward the tip end side of the pipe member along the pipe member, and in the open position, the handle member is disposed so as to extend toward the side or the oblique side of the pipe member. When cutting a branch, hold the grip part of the handle member with one hand, hold the pipe member with the other hand, insert the branch into the open blade, and use the other hand to apply the operating force acting on the pipe member. While receiving, the handle member is pushed to the pipe member side with one hand, and the handle member is turned from the open position to the closed position, thereby cutting the branch. If necessary, the pipe member is brought into contact with the waist or flank, and the handle member is operated to the closed position with one hand while receiving the operating force acting on the pipe member with the waist or flank, and the branch is cut. Will do. In this way, the branch can be cut by operating the handle member with the entire arm, so that it is easier for women and elderly people with weak grip strength to cut branches compared to the case of cutting branches with grip strength as in the past. Moreover, the operator's fatigue can be reduced. Compared to conventional movable levers, the distance from the pivot center of the handle member to the grip part can be increased, so that it is possible to apply a large force to the fixture without difficulty due to the lever principle. Even relatively thick branches of 15 to 20 mm can be easily cut.

  Here, in the open position, an angle θ formed by a straight line passing through the rotation center of the handle member and the tip of the handle member and the center line of the pipe member is preferably 60 ° to 120 °. It is a form. If the angle θ is less than 60 °, the angle range in which the handle member can be operated becomes small, the opening / closing angle of the tool blade is reduced, and the amplification effect of the operating force is reduced. If the angle exceeds 60 °, the angle between the forearm portion and the upper arm portion of the arm of the operator who operates the handle member becomes large, making it difficult to apply force to the handle member, so the angle θ is 60 ° to 120 °. It is preferable to set to.

  When the distance between the rotation center of the handle member and the tip of the handle member is L1 (mm), and the distance between the connection portion of the handle member and the rotation center of the handle member is L2 (mm), 3 It is preferable that the relationship of ≦ L1 / L2 ≦ 10 is satisfied. When L1 / L2 is less than 3, the operation force amplification effect at the time of branch cutting cannot be sufficiently obtained. When L1 / L2 exceeds 10, the operation force amplification effect becomes too great, and the transmission means and Since the tool may be damaged, it is preferable to set 3 ≦ L1 / L2 ≦ 10.

  It is also a preferred embodiment that the handle member is configured to be adjustable in length. Such a configuration is preferable because the length of the handle member can be adjusted according to the thickness of the branch to be cut and the branch can be cut with an appropriate force.

  In a preferred embodiment, the handle support member is provided so as to be rotatable about the central axis of the pipe member and immovable in the central axis direction of the pipe member with respect to the pipe member. With this configuration, the position of the tool blade and the position of the handle member can be adjusted with respect to the circumferential direction of the pipe member. It can be adjusted to a suitable circumferential position.

  In the closed position, it is preferable to provide a gap between the handle member and the pipe member that can prevent a hand holding the grip portion of the handle member from coming into contact with the pipe member. By comprising in this way, the malfunction of pinching a finger | toe between a grip part and a pipe member and being damaged can be prevented reliably.

  As the pipe member, it is also preferable to provide a plurality of pipe members that can be extended and contracted. This is preferable because the length of the pipe member can be adjusted according to the height of the branch to be cut.

  According to the high branch cutting device according to the present invention, the handle member can be operated with the entire arm to cut the branch. Therefore, compared to the case where the branch is cut with a grip force as in the conventional case, a woman or an elderly person who has a weak grip force. However, it can be easily debranched and the operator's fatigue can be reduced. Compared to conventional movable levers, the distance from the pivot center of the handle member to the grip part can be increased, so that it is possible to apply a large force to the fixture without difficulty due to the lever principle. Even relatively thick branches of 15 to 20 mm can be easily cut.

In the present embodiment, the case where the present invention is applied to a high branch cutting rod 1 having two pipe members 2 and 3 that can be expanded and contracted will be described. However, the number of pipe members other than two, for example, one pipe member is used. The present invention can be similarly applied to a high branch cutting rod having three or more pipe members connected in a stretchable manner.

  The length adjusting means 10 will be described. As shown in FIGS. 2 and 4, both the pipe members 2 and 3 are constituted by hollow pipe members having a length, and the top surface of the distal end side pipe member 2 has a length direction. Adjustment holes 11 are formed at regular intervals, and one insertion hole 12 is formed in the vicinity of the distal end of the proximal end side pipe member 3 so as to correspond to the adjustment holes 11. A substantially cylindrical fixture 13 is fixed to the distal end portion of the base end side pipe member 3, and an adjustment lever 14 is pivotally supported around the support shaft 17 at the upper portion of the fixture 13.

Thus, the engagement of the locking pin 15 with respect to the adjustment hole 11 can be released, and the extension amount of the distal end side pipe member 2 with respect to the proximal end side pipe member 3 can be adjusted, and the locking pin 15 is engaged with the adjustment hole 11. In this manner, the pipe members 2 and 3 can be connected to a desired length in a non-stretchable manner in a stepwise manner between the contracted position shown by the solid line in FIG. 1 and the extended position shown by the phantom line. Yes.

  As shown in FIGS. 2, 3, 5, and 6, the operation means 20 includes a handle support member 21 provided at a proximal end portion of the proximal end side pipe member 3, and substantially orthogonal to the proximal end side pipe member 3. A handle member 22 rotatably supported by the handle support member 21 around the shaft center, and a transmission means 40 for transmitting the operating force of the handle member 22 to the fitting 50. The grip portion 22a of the handle member 22 is 2, and grip the handle 4 covered with the other hand in the middle of the lengthwise direction of the proximal end side pipe member 3 with the other hand, and the handle member 22 is shown in the open position shown in phantom lines in FIG. In addition, the movable blade 53 of the fixture 50 is opened and closed between an open state and a closed state by performing a rotation operation over the closed position shown in the solid line.

And a housing support portion 24 for housing and supporting the housing. Reference numeral 33 denotes a sliding sleeve provided between the base end side pipe member 3 and the base portion 23 in order to improve the sliding of the base portion 23.

  A slit 23a extending in the circumferential direction is formed in the middle portion in the length direction of the base portion 23 so as to penetrate therethrough, and a head portion 25a is disposed in the slit 23a in the vicinity of the proximal end of the proximal end side pipe member 3. As shown in FIGS. 3 and 6, the handle screw 21 is fixed to the base end pipe member 3 by the slit 23 a and the restriction screw 25, as shown in FIGS. 3 and 6. In the range of the angle α that contacts the end of the slit 23a, it is relatively rotatable and attached so as not to move relative to the axial direction.

  As shown in FIGS. 2, 3, and 5, the handle member 22 includes a grip portion 22 a that can be gripped by hand, a pivot portion 22 b with respect to the handle support member 21, and transmission from the distal end side in the length direction. And a connecting portion 22c for the means 40.

  The handle member 22 is formed in a gently curved shape having a center on the pipe member side, and a support shaft 26 is inserted into the pivotal support portion 22b of the handle member 22 so as to be substantially orthogonal to the proximal end side pipe member 3. Both end portions of 26 are supported by the handle support member 21 in a erected manner, and the handle member 22 has a grip portion 22a that is substantially parallel to the proximal end side pipe member 3 via the support shaft 26, and the proximal end side pipe member. 2 extending toward the distal end side of FIG. 3, and a handle that is pivotable between a closed position illustrated by a solid line in FIG. 2 and an open position illustrated by a virtual line in FIG. 2 extending to the side of the proximal end side pipe member 3. It is supported by the support member 21.

  A spring member 27 made of a torsion coil spring is externally mounted on the pivot portion 22b, and the handle member 22 is constantly urged toward the open position by the spring member 27. A hook portion 28 is provided at the lower end of the base end of the grip portion 22a, and a regulating member 29 made of a rubber member or the like that can contact the hook portion 28 is provided at the upper portion of the base portion 23 of the handle support member 21. 22, when the hook portion 28 abuts on the regulating member 29, the rotation of the proximal end side pipe member 3 from the closed position is restricted, and between the grip portion 22 a and the proximal end side pipe member 3 in the closed position. A gap 30 in which a finger can be inserted with play is formed, so that when the handle member 22 is closed, the finger gripping the grip portion 22a does not come into contact with the proximal pipe member 3. Yes. A U-shaped stop member 31 is rotatably provided at the base of the restricting member 29, and the handle member 22 can be held in the closed position by hooking the stop member 31 on the hook portion 28. .

  A pair of left and right connecting portions 22c are provided substantially parallel to each other, and a connecting pin 32 is rotatably provided across the pair of connecting portions 22c so as to be substantially orthogonal to the proximal end side pipe member 3. An insertion hole 32a is formed in the middle of the connection pin 32 so as to be orthogonal to the length direction of the connection pin 32, and the base end of the operation rod 41 of the transmission means 40 is inserted into the insertion hole 32a. The operation rod 41 of the transmission means 40 is pulled by operating the handle member 22 to the closed position.

  In the open position indicated by the phantom line in FIG. 2, the angle θ formed by the straight line HL passing through the rotation center of the handle member 22 and the tip of the handle member 22 and the center line PL of the pipe member is 60 ° to 120 °. The angle is preferably set to 70 ° to 110 °, more preferably 80 ° to 100 °. When the angle θ is less than 60 °, the angle range in which the handle member 22 can be operated becomes small, the opening / closing angle of the movable blade 53 of the fixture 50 becomes small, and the amplification effect of the operating force becomes small. If the angle exceeds 120 °, the angle formed by the forearm portion and the upper arm portion of the arm of the operator who operates the handle member 22 becomes large, and it becomes difficult for force to be applied to the handle member 22. Is preferably set to 60 ° to 120 °.

  The distance between the rotation center P of the handle member 22 and the tip of the handle member 22 is L1 (mm), and the distance between the connection portion 22c (the center of the connection pin 32) of the handle member 22 and the rotation center of the handle member 22 is set. Is set to satisfy L ≦ L1 / L2 ≦ 10, preferably 5 ≦ L1 / L2 ≦ 8. When L1 / L2 is less than 3, the effect of amplifying the operating force (branch cutting force) of the fitting 50 with respect to the operating force of the handle member 22 cannot be sufficiently obtained. Since the amplification effect becomes too great and the transmission means 40 and the fitting 50 may be damaged, it is preferable to set 3 ≦ L1 / L2 ≦ 10.

  The transmission means 40 will be described. As shown in FIGS. 2 to 4, an operating rod 41 that is pulled by the handle member 22 is provided in the proximal end pipe member 3, and the operating rod 41 is a proximal end pipe member. 3, the distal end portion thereof is disposed near the distal end portion of the proximal end side pipe member 3, and the holder member 43 is coupled to the distal end portion of the operation rod 41 at a position corresponding to the fixture 13. The holder member 43 is rotatably provided with a connecting member 44 that is elongated in the front-rear direction so as to always face the insertion hole 12, and the connecting member 44 is constantly urged upward by the spring member 45 to be connected to the connecting member 44. The engaging piece 46 is formed so as to protrude sideways. An operating rod 47 whose tip is connected to the lower end of the movable blade 53 is provided in the distal end side pipe member 2, and a notch 48 that can be engaged with the engaging piece 46 is provided on the upper portion of the operating rod 47. A plurality are provided at the same interval as 11. The biasing force of the spring member 45 that biases the connecting member 44 upward is set smaller than the biasing force that biases the connecting member 44 downward via the locking pin 15 by the spring member 16 of the length adjusting means 10. In the locked state of the length adjusting means 10, as shown in FIGS. 2 and 4, the connecting member 44 is disposed substantially parallel to the inner surface of the proximal end side pipe member 3, and the engaging piece 46 of the operation rod 47 is engaged. When the lock is released, the distal end portion of the connecting member 44 is rotated upward and comes into contact with the inner surface of the distal end side pipe member 2, so that the operation rod 47 is engaged. The joining piece 46 is configured to be detached from the notch 48 of the connecting member 44.

  For this reason, in this operating means 20, when the locking pin 15 protrudes into the distal end side pipe member 2, that is, when the adjustment lever 14 is not operated, the connecting member 44 is pushed downward by the locking pin 15. Then, when the engagement piece 46 is engaged with the notch 48 of the operation rod 47 and the handle member 22 is operated to the closed position side in this state, the operation rod 41 and the operation rod 47 are pulled to the proximal end side, and the movable blade When 53 is closed and the operation of the handle member 22 is loosened, the handle member 22 is returned to the open position side by the spring member 27, and the operation rod 41 and the operation rod 47 are moved to the distal end side. Opened. Further, when the handle member 22 is opened and closed, even if the operation rod 41 and the operation rod 47 move back and forth, the connecting member 44 is always pushed down by the locking pin 15, and the engagement piece 46 is always engaged with the notch 48. Since the combined state is maintained, the movable blade 53 can be opened and closed in conjunction with the operation of the handle member 22. On the other hand, when the base end side portion of the adjustment lever 14 is pushed and the locking pin 15 is moved above the adjustment hole 11, the connecting member 44 is rotated upward and the engagement piece 46 is notched 48. When the locking pin 15 is engaged with the adjustment hole 11 with the lengths of the pipe members 2 and 3 adjusted and the pipe members 2 and 3 are adjusted in length. Since it is provided corresponding to the adjustment hole 11, the engaging piece 46 of the connecting member 44 engages with the corresponding notch 48, and the movable blade 53 is interlocked with the operation of the handle member 22 as described above. It is comprised so that opening and closing operation can be carried out. It should be noted that the length adjusting means 10 and the transmitting means 40 can adopt configurations other than the above-described embodiment.

  As shown in FIGS. 2 and 4, the fixture 50 is pivotally pivotable to a fixed receiving member 51 attached to the distal end portion of the distal end side pipe member 2 and the fixed receiving member 51 via a pivot shaft 52. A movable blade 53 as a supported blade, a cover member 54 covering the movable blade 53, and a torsion spring 55 that constantly urges the movable blade 53 so as to be covered by the cover member 54 are provided.

  The blade portion 53a of the movable blade 53 is formed of an anvil blade, and an operation portion 53b extending downward is formed on the movable blade 53. The lower end portion of the operation portion 53b is rotatable to the tip portion of the operation rod 47 of the transmission means 40. It is connected to. The fixed receiving member 51 is formed with a receiving portion 51a capable of receiving the blade portion 53a. With the branch B inserted between the blade portion 53a and the receiving portion 51a, the movable blade 53 is rotated to the closed state. The blade portion 53a and the receiving portion 51a are configured so as to be cut with the branch B interposed therebetween. However, as the jig 50, one having a configuration other than those described above can be adopted, and for example, a tool having a fixed blade and a movable blade can be adopted. It is also possible to employ a fitting 50 that does not include a cover member.

  When cutting the branch B in the high branch cutting rod 1, after adjusting the length of the high branch cutting rod 1 by the length adjusting means 10, as shown in FIGS. 1, 2, and 4, the fixed receiving member 51. The branch B is inserted between the receiving portion 51a and the blade portion 53a of the movable blade 53, the handle member 22 is operated to the closed position, and the movable blade 53 is closed, so that a branch is formed between the blade portion 53a and the receiving portion 51a. B will be cut off. More specifically, the handle member 22 is disposed along the proximal side pipe member 3 with the distal end side directed toward the distal end side of the proximal end side pipe member 3 in the closed position illustrated by a solid line in FIG. In the open position shown by the phantom line in FIG. 2, it is arranged so as to extend to the side or the oblique side of the proximal end side pipe member 3, so when cutting the branch B, as shown in FIG. The branch B is inserted into the opened movable blade 53 in the state where the grip portion 22a of the handle member 22 is gripped and the grip 4 of the proximal end side pipe member 3 is gripped by the other hand, and acts on the proximal end side pipe member 3. The handle member 22 is pushed by one hand toward the proximal end side pipe member 3 while receiving the operation force to be performed with the other hand, and the handle member 22 is rotated from the open position to the closed position, thereby B will be cut off. Further, as shown in FIG. 7, the base end side pipe member 3 is brought into contact with the waist or the flank as required, and the handle member is received while the operation force acting on the base end side pipe member 3 is received by the waist or the flank. The branch B is cut by operating 22 to the closed position. In this way, the handle B can be cut by operating the handle member 22 with the whole arm, so that even a woman with weak grip strength or an elderly person can easily branch compared to the case where the branch B is cut with grip strength as in the prior art. The cutting operation can be performed, and the operator's fatigue can be reduced. In addition, since the distance from the rotation center of the handle member 22 to the grip portion 22a can be increased as compared with the conventional movable lever, a large force can be applied to the fitting 50 without difficulty due to the lever principle. Thus, it goes without saying that thin branches can be easily cut even with relatively thick branches having a diameter of 15 to 20 mm.

  In order to adjust the length of the handle member 22, as shown in FIG. 8, an extension handle 60 made of another member is detachably connected to the handle member 22, or as shown in FIG. An auxiliary handle 62 is provided at the distal end portion of the shaft 22 so as to be rotatable about the support shaft 61, and as shown in FIG. 10, the distal end portion of the handle member 22 is extendable and retractable along a pair of guide pins 63. An auxiliary handle 64 can also be provided.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and it goes without saying that the configuration can be changed without departing from the gist of the present invention.
