Description

  The present invention relates to a manual binding tool for a binding band.

  As a conventional manual binding tool, there is one disclosed in Patent Document 1. This consists of a receiving lever and an operating lever that are pivotally connected to each other in the middle part from the tip in the longitudinal direction, and a cut lever that is pivotally supported by the receiving lever. It is a manual type tool that acts on a binding band that is present and tightens the band for good binding.

  The manual binding tool described above is provided with a mechanism capable of locking the band portion of the binding band at the distal end portion of the operating lever, and is configured to be able to receive the head portion of the binding band at the distal end portion of the receiving lever. The band portion can be forcibly pulled and tightened with respect to the head portion using the fact that the receiving lever and the tip end portion of the action lever move apart by the grip operation of the lever and the action lever. And after tightening, the band part can be cut | disconnected by the base part of a head part with the cutting blade which protrudes and moves by holding | griping a cut lever.

  In that case, it is necessary to insert the band portion through the band insertion hole formed in the tip portion of each lever from the tip portion in advance, which is troublesome. That is, when bundling with a manual bundling tool, the tool is moved closer to the bundling band temporarily fixed to the bundling target, so a relatively heavy tool made of metal is moved to move the tip of the bundling band. Although it is necessary to pass the band part through the small hole, it is difficult to move the tool having a much larger inertial mass than the band part and pass it through the hole, and it takes a relatively long time. For this reason, when the number of bundling operations is performed, the wrist and the like tend to be fatigued.

As described above, the binding work of the binding band by the current manual binding tool is troublesome and relatively time-consuming to set the band on the tip of the tool for binding, and it is easy to get tired if the binding work is continued. It was something that left room for improvement.

  According to the present invention, since the band portion can be placed on the tool main body only by moving the tool main body laterally in order to tighten the band portion, it can be inserted into the insertion hole formed at the tip of the tool main body. Compared to conventional tools that allow the band part to be inserted through the band part from the open end and moved along the longitudinal direction of the band part, the tightening and cutting arrangement operation of the band part, that is, the setting operation is simple. Can be done quickly. As a result, it is possible to realize and provide an improved manual bundling tool which is easy and easy to set the tool tip to the band portion of the bundling band, and is less likely to get tired even if the number is increased. In addition, the above-mentioned conventional tool cannot be used for a binding band having a structure in which the head portion and the band portion are separated from each other and cut into an appropriate length from the super-long band portion wound in a coil shape. However, the manual bundling tool of the present invention that can be moved and moved laterally has an advantage that it is possible to bind the bundling band having such a structure.

If the structure is such that the tightening mechanism is activated by grasping the first lever and the second lever and the cutting mechanism is activated by grasping the first lever and the cutting lever, the operation with fingers is It is possible to provide a convenient manual bundling tool that is easy to perform and that allows the setting operation by lateral movement of the tool body to be performed by a simple operation of inserting the band portion into each groove formed at the tip of each of the first and second levers.

If the structure in which the cutting blade moves across the lateral groove by grasping the cutting lever as in claim 2 is adopted, the surplus band portion is formed in a state where the uncut residue does not protrude from the head portion as much as possible while making the structure simple. It becomes possible to cut.

If the return spring for returning the cutting blade to the retracted position also serves as a spring for returning and urging the first lever and the second lever to the closed state as in claim 3 , the return spring is provided for each. Compared to the above, the number of springs can be reduced, and it is possible to provide a rational manual bundling tool capable of reducing the cost and simplifying the structure.

The band holding portion configured by the self-locking structure of the locking piece supported to be swingable as in claim 4 makes the band portion strong against the tensile force by using the tensile force of the tightening mechanism. A reasonable structure that can be held is obtained, and the holding of the band of the locking piece is released when the first lever and the second lever are released, and the holding of the band starts by holding the first lever and the second lever. Therefore, a special operation for holding the band is unnecessary, and it is easy to handle and operate manually that can hold and tighten the band part and hold and cut the band part simply by grasping and releasing the lever. A binding tool has been obtained.

If a tightening force adjusting device capable of adjusting the tightening force is provided as in claim 5 , the tightening force varies for each binding band, or even if a single type of binding band has different operators, there is a difference in tightening force. It is possible to provide a useful manual bundling tool that has never been performed and can bind a plurality of bundling bands with a uniform tightening force regardless of who is working. There is also the convenience that the tightening force can be adjusted and set appropriately depending on the type of binding object and the type of binding band.

As in claim 6 , if the second lever is a hip folding lever and the hand lever part is bent with respect to the tip lever part when the tightening force reaches a set value, the tightening force is maintained at the set value, By the bending, the operator can be informed that the tightening force has reached the set value. Then, the set tightening force can be adjusted by adjusting the difficulty of bending. As a result, it is possible to provide a manual bundling tool that is excellent in usability because it can detect the set tightening force, hold the set value, and report it to the operator all at once by simply performing a gripping operation with fingers.

The invention according to claim 7 is the embodiment of the tightening force adjusting device according to claim 6 , wherein the engagement state by pressing and fitting the concave portion and the convex portion with the coil spring is the first lever and the second lever. The second lever breaks when it is released when the gripping force exceeds a predetermined value, and the second lever is equipped with all components such as coil springs, screw shafts, and knobs. A device can be configured.

As in claim 8 , the pivotal connection point between the tip lever part and the hand lever part in the second lever and the pivotal connection point of the first and second levers are the same, simplifying the configuration and reducing costs. It is possible to provide a preferred manual bundling tool that facilitates a possible streamlined configuration.

It is pivotally supported by a heart p2 so that it can swing. The action arm 24 is connected to the tip end portion of the slide member 26 via an intermediate link 25 made of a pair of steel plates. The intermediate link 25 is connected to the action arm 24 via a stepped pin 24b and to a pin shaft 31. Are respectively pivotally connected to the slide member 26. A cylindrical roller (an example of a convex portion) 34 that can be fitted into and engaged with the engaging concave portion 12 c of the regulating member 12 is loosely fitted to the stepped pin 24 b of the action arm 24. With such a configuration, the compression coil spring 32 presses and biases the action arm 24 around the second axis p <b> 2 via the slide member 26 and the intermediate link 25, and the roller 34 engages with the engagement recess 12 c. Therefore, the second base end portion 2A and the second tip end portion 2B are usually integrated with each other. Accordingly, if the first base end portion 1A and the second base end portion 2A are gripped so as to approach each other, the first tip end portion 1B and the second tip end portion 2B move away from each other.

  Even if the tightening force of the band portion a reaches the set value due to the separation movement between the first tip portion 1B and the second tip portion 2B, if the second lever portion 2a is still gripped, the engagement with the roller 34 by the compression coil spring 32 is engaged. The roller 34 is moved up and moved on the escape movement surface 12d against the engaging force with the fitting recess 12c, and the second base end 2A rises and swings around the main axis P with respect to the second tip 2B, that is, hips break. It swings and functions so that the tightening force does not increase any more (see FIG. 10). Since the set tightening force depends on the engaging force between the roller 34 and the engaging recess 12c, that is, the elastic force of the compression coil spring 32, the receiving plate member 28 is operated by the turning operation of the knob 27a exposed to the outside. If the compression coil spring 32 is compressed by moving the position forward (to the main axis P side), the set value can be increased and the tightening force can be increased, and the position of the backing plate member 28 can be moved backward (knob 27a). If the compression coil spring 32 is extended by moving the compression coil spring 32, the set value becomes lower and the tightening force can be reduced.

  FIG. 7 shows, as an example, a state in which the receiving plate member 28 is closest to the knob 27a side and the compression coil spring 32 is most extended to be adjusted to a loose tightening force. At this time, the mark portion 28a is located on the most proximal end side of the long notch 21, as indicated by a virtual line in FIG. 5A shows an intermediate tightening force setting state in which the knob 27a is turned so that the mark portion 28a of the receiving plate member 28 is located at the center of the long notch 21, and FIG. 5B shows the mark portion 28a. Is the strongest tightening force setting state in which the knob 27a is turned so that it is positioned on the most distal side of the long notch 21.

  Next, a series of bundling operations using the manual bundling tool according to the first embodiment will be described. First, as shown in FIG. 6, the manual binding tool A is moved laterally, the band part a of the binding band B temporarily fixed to the binding target K is taken into the insertion groove m1 and the lateral groove m2, and then the manual binding tool A is lowered slightly to move it closer to the head part b, and the tightening start state shown in FIG. In the tightening start state shown in FIG. 7, it is desirable that the head portion b is in contact with the lower surface of the second tip portion 2B, but this is not necessary. In FIG. 7, the second lever 2 indicated by the solid line is the opening position R with respect to the first lever 1, and the second lever 2 indicated by the phantom line is the first lever in which the stopper portion 22 is in contact with the first lever 1. The limit closing position T for the lever 1 is shown respectively. In FIG. 7, hy, ny, ky, and cy are the index finger, middle finger, ring finger, and little finger of the fingers that hold the second lever, respectively.

  Then, the base end portion 1A of the first lever 1 and the base end portion 2A of the second lever 2 are gripped with fingers, and as shown in FIG. 8, the stopper portion 22 of the second lever portion 2a is moved to the first lever. The first lever 1 and the second lever 2 are swung around the main shaft center P until they come into contact with the back surface of 1, the first tip portion 1B and the second tip portion 2B are moved away from each other, and the band portion a is pulled. To tighten the binding object k. At this time, as will be described in detail in the subsequent cutting step, the band holding portion g is activated by a slight grasp from the tightening start state shown in FIG. 7 (open position R → hold start position V: see FIG. 12). The locking piece 4 can project and move to be firmly locked and held by a self-locking action by sandwiching the band portion a between the anti-slip portion 4A and the laterally facing portion 6, and the two ends thereafter. The state which enables the tightening by the separation movement of the parts 1B and 2B is obtained.

  Now, in the tightening end state shown in FIG. 8, the grip is released and the tightening start state shown in FIG. 7 is restored. Then, the first base end portion 1A and the second base end portion 2A are gripped again, and the second tightening is started. Then, as shown in FIG. 9, when the set tightening force is reached at the intermediate position Q during the second or third gripping, the second base end portion 2A around the main shaft center P as shown in FIG. Sway and swing relative to the second tip 2B, the second tip 2B does not move and the set tightening force is maintained, and the operator has reached the set tightening force because the grip is suddenly lightened. It will be understood. In this waist-folding state, the second tip portion 2B does not move even if the gripping operation is further performed, so that the tightening action by the tightening mechanism c becomes impossible. The set tightening force is set in advance by the tightening force adjusting device C described above.

  When the band part a is tightened, the fingers hy, ny, ky, cy hung on the second lever 2 are re-hanged on the cutting lever 3 and straddle the first lever 1 as shown in FIG. The state is changed to the gripping cutting start state, and the band portion a after being tightened is again taken into the taking-in groove m1 and the lateral groove m2 to be in a hand-held state. When the band part a once separates from the grooves m1 and m2 with the completion of tightening, the manual binding tool A is again moved laterally and the band part a is taken into the grooves m1 and m2. In the free state of the manual binding tool A shown in FIG. 11, the cutting lever 3 is in the standby position t that is fully opened with respect to the second lever 2.

  When the cutting lever 3 at the standby position t is grasped to the action starting position v so that the second lever 2 swinging slightly from the cutting start state is located at the holding start position V from the open position R, FIG. As shown in FIG. 12, the first tip portion 1B and the second tip portion 2B are slightly separated from each other, the interlocking mechanism r is actuated, and the locking piece 4 swings and moves in a direction protruding into the intake groove m1, thereby preventing slippage. The band holding state in which the portion 4A is in contact with the band portion a is envisaged. Strictly speaking, the non-slip portion 4A comes into contact with the band portion a, and the second tip portion 2B relatively moves away from the first tip portion 1B from the state to pull the band portion a, thereby A self-locking operation occurs when the locking piece 4 tries to swing in the direction of arrow B, and the band portion a can be firmly locked and held by the laterally directed portion 6 and the locking piece 4. The cutting lever 3 swings from the standby position t to the action start position v with respect to the first lever 1, but does not swing in a direction that is relatively gripped by the second lever 2 that swings together. The cutting blade 33 is still in the retracted position i.

  When the cutting lever 3 is still grasped from the state shown in FIG. 12 and moved upward and swinging from the standby position t to the grasping position s with respect to the second lever 2, it acts against the urging force of the return spring 5. The bar 3a pushes the vertical wall portion 33B to move the cutting blade 33 to the protruding position q with respect to the second tip portion 2B. As shown in FIG. 13, the lower end position of the lateral groove m2, that is, the upper surface of the head portion b is passed. The band part a is cut at the position. In this band cutting process, the second lever 2 tries to move along with the grasping of the cutting lever 3, whereby the band holding mechanism g is actuated and the band portion a is pulled and tensioned, and the sliding blade The band portion a can be cut smoothly and satisfactorily by 33a. The band part a that has been cut and remains in the intake groove m1 and the lateral groove m2 can be easily removed from each of the grooves m1 and m by moving the band part a and the manual binding tool A relative to each other. It is possible to prepare for the next bundling operation.
