Description

  The present invention is an operation handle for operating various work tools attached to the end of a long handle used as a work tool for high places in fruit gardening, landscaping, forestry, construction / painting sites, overhead wire repair work sites, etc. It is about.

  As an operating device for operating various work tools attached to the long pattern tip, in particular, the distance between the tip portion and the operation portion can be adjusted and the tip portion can be bent. There are methods such as 3116430 and 3117218.

  However, even if the structure of the above device is suitable for a work tool that requires an operating force greater than the operating distance of the driving force transmitted to the long handle tip, such as a pruning shear, it can be held by a high branch saw (utility model registration No. 3120695). Equipment and fruit remover (utility model registration No. 3119046), fruit harvesting tool (utility model application number: actual application 2006-1522), drug sprayer, spray gun for painting, etc. The required working tool was not always satisfactory because of its short operating distance.

  In view of such a situation, the present invention has been made in order to embody an operation handle capable of sending a linear driving force having a relatively long operating distance to various working tools at the long handle tip.

Means to solve the problem

Constitution

  The handle (3) of the present invention is mounted near the rear end of the long handle (1), and a work tool corresponding to various operations is mounted on the front end of the long handle, and both are engaged by the cable wire (2). .

  The long handle (1) is a straight pipe having a length suitable for work, but depending on the structure of the work tool attached to the tip, the outlet (1a) for leading the cable wire to the middle part of the long handle Is dawned.

  The cable wire (2) is generally called a Bowden cable, and an inner cable (2a) made by twisting many thin steel wires is covered with an outer tube (2b, 2e) in which the steel wires are wound spirally. It is in a wrapped structure and can be bent relatively flexibly. The cable wire may be supported by an appropriate support member provided outside the long handle depending on the work tool at the end of the long handle, but in many cases, the inside of the pipe-like long handle is near the tip of the long handle (1). And is led out of the long handle from the outlet (1a) opened in the middle portion of the long handle and engaged with the handle (3). Further, the outer tube is divided into two near the outlet, the front fixed outer tube (2e) is fixed near the work tool attached to the long handle tip, and the rear movable outer tube (2b) is rear The end is in contact with the terminal locking member (2c) of the inner cable. That is, the inner cable (2a) is encapsulated in the fixed outer tube (2e) from the front end to the vicinity of the outlet (1a), and is encapsulated in the movable outer tube (2b) from the vicinity of the outlet to the rear end. .

  The handle (3) is mounted on the rear side of the long handle with the long handle inserted into the upper handle cylindrical portion (3a), and its movement is restricted by the grip bolt (4). That is, when the handle bolt is loosened, the handle has a structure capable of adjusting the distance from the leading end and the angle of the long handle as the central axis between the outlet (1a) and the rear end of the long handle.

  A lever pin (5) is provided at the lower end of the handle (3), and a lever (7) is pivotally attached to the lever pin. Further, at the upper end portion of the lever, a lower holding piece (a rectangular parallelepiped integrated with the lever) 7a), the lower holding piece has a holding body pin (8), and the upper holding piece (7b) is pivotally attached to the holding body pin. In other words, the upper end of the lever is divided into a lower holding piece (7a) and an upper holding piece (7b) at the holding pin part, and constitutes a holding body.

  A roller (9) is pivotally mounted near the upper left and right of the upper clamping piece, and the roller is in contact with guide rails (10) provided on the lower left and right sides of the handle cylindrical portion (3a).

  Most of the guide rail (10), that is, the rearward arcuate portion (10a) has an arc centered on the lever pin (5), and only the front portion, that is, the hook-like portion (10b) has a round hook shape. ing.

  The lever (7) is biased forward by the spring (6) within a range in which the roller (9) is regulated by the hook-shaped portion (10b) of the guide rail. In this state, the hook-shaped portion Guides the roller upward to open the upper clamping piece (7b).

  The cable wire (2) is inserted between the lower holding piece and the upper holding piece, but the lever is pushed forward, that is, the roller (9) is in the hook-like portion (10b) of the guide rail. When there is no, there is no engagement relationship and it is free. However, when the lever is gripped, the roller (9) is pushed downward under the restriction of the arc portion (10a) of the guide rail. Along with this, the upper holding piece closes and the movable outer tube (2b) of the cable wire inserted between the holding pieces is pinched and pulled backward.

  Opposite surfaces of both clamping pieces are engraved with a groove in the front-rear direction suitable for clamping the cable wire (2), and are further processed to suppress wear of the movable outer tube and to ensure grasping. .

  The rear end portion of the cable wire (2) inserted between the sandwiching bodies passes rearwardly from a through hole (3b) opened near the grip portion of the handle, and at the rear end portion, the end sleeve (2d) of the movable outer tube Is in contact with the terminal locking member (2c) of the inner cable, and the movement of the movable outer tube is transmitted to the inner cable (2a) at the rear end, and further to the work tool attached to the front end of the long handle. It is in the structure.

Functions and interrelationships of each part

  The long handle (1) is for facilitating the approach to an object above the head according to each work purpose.

  The cable wire (2) transmits the driving force when the rear handle (3) is operated to the work tool at the end of the long handle. At that time, the movable outer tube (2b) transmits the driving force received from the holding body of the lever (7) to the inner cable (2a) at the rear end, and further, the inner cable transmits the driving force to the work tool at the tip. To do. The fixed outer tube (2e) serves to guide the movement of the inner cable (2a) inside the bent portion or the long handle near the tip.

  The handle (3) holds the operating parts of the present invention and serves as a driving force source for operating various working tools. When the lever (7) of the handle is gripped, the roller (9) is pushed downward under the restriction of the guide rail (10), and accordingly, the upper clamping piece (7b) is closed, and between the clamping bodies. The movable outer tube (2b) of the inserted cable wire is pinched and pulled backward.

  It is the movable outer tube (2b) that the clamping body of the lever (7) clamps and pulls backward, and the terminal sleeve (2d) of the movable outer tube is the rear end portion of the terminal locking member (2c) of the inner cable. The driving force is transmitted to the inner cable in contact with the inner cable, and the working tool attached to the long pattern tip is operated in accordance with this movement.

  When the lever (7) is released, the lever is returned to the front by the urging force of the spring (6), and accordingly, the roller (9) is guided to the hook-shaped portion (10b) of the guide rail and the upper clamping piece is moved. Open and the engagement relationship between the handle (3) and the cable wire (2) is broken.

  The working part of the work tool is restored by the urging force of the spring provided in the work tool.

  The cable wire (2) is not clamped except when the lever (7) is gripped. By simply loosening the grip bolt (4), the handle position and posture angle can be adjusted according to the distance from the object and workability. Adjustment is possible.

how to use

  It is assumed that the operation handle of the present invention is mounted near the rear end of a long handle equipped with a work tool.

  When it is necessary to adjust the distance to the work object, the handle bolt and the posture angle are adjusted by loosening the grip bolt (4).

  When the leading end of the long pattern reaches the object, grasp the handle and grasp the lever (7). As a result, the driving force is transmitted to the distal end portion via the cable wire, and the operating portion of the working tool is operated.

  Release the lever when you have finished the desired action. The working part of the work tool is restored by the urging force of the spring provided in the work tool.

  If it is necessary to store the work tool equipped with the handle of the present invention after completion, the handle (3) is pulled toward the rearmost end, and the end sleeve (2d) of the cable wire is moved backward through the through hole (3b). Pull and tighten the grip bolt (4) in that position. As a result, it is possible to store the working tool in a state in which the operating portion is pulled.

Effect of device

  The operation handle of the present invention is used in combination with a high-edged saw gripping device mounted on a long handle, a fruit torsion harvester, a spray nozzle for control, a spray gun for painting, etc., so that a longer operating distance is secured and operability is improved. Improved.

Example of use

  FIG. 5 shows a usage example in which the handle of the present invention is used for a fruit harvesting tool (utility model application number: actual application 2006-1522).

Best mode for carrying out the invention

  In the present invention, it is assumed that a cable wire that can be flexibly bent is used as the linear driving force transmission member, considering that various work tools mounted on the tip of a long handle often have a bending structure. did. Here, it is possible to use only the inner cable made by twisting the steel wire, but if the inner cable is directly clamped while ensuring the movability of the operation position, can the grasping force be obtained sufficiently? If the measure for increasing the grasping force is taken, the inner cable may be worn out at an early stage, and the mobility of the operation position is also impaired. From the viewpoint of preventing this wear and securing the grasping force of the cable wire, avoid the direct clamping of the inner cable by the clamping body of the lever part, and sandwich and move the movable outer tube as a primary linear driving force transmission medium, It can be said that it is a good measure to transmit to the inner cable secondarily.
