BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a binding band according to the present invention. FIGS. 1, 2 and 3 show that a band 1 made of iron is formed at one end with a head 2 wider than the band 1 and at the other end with a tapered tail 4. It is an example of the binding band according to the present invention.

A through hole 5 through which the band 1 is inserted is formed in the head 2 on an extension of the band 1, and the through hole 5 is formed as shown in FIG.
As shown in FIG. 3, an approach portion 6 slightly wider than the width of the band portion 1 and located on the base end side of the head portion 2 and a holding portion 7 narrower than the width of the band portion 1 and located on the distal end side of the head portion 2 are provided. It has a trapezoidal shape sandwiched between left and right holding edges 8, 8, which are communicated with each other and are symmetrical in shape. When a dedicated binding device is used, a small hole 25 is formed in the center of the tail portion 4 as the hooking portion 3, or a symmetrical constriction 26 is provided at the tip of the tail portion 4 as shown in FIG.

The holding portion 7 is a part of the entire through-hole 5 and is located on the tip side of the head 2 with respect to the entry portion 6. The sandwiching edge 8 is a side edge of the sandwiching portion 7, and a force for sandwiching the side edge of the band portion 1 increases with a return force of the band portion 1 inserted through the through hole 5. That is, a side edge inclined approximately symmetrically with respect to the longitudinal direction of the band portion 1 so that the interval between the left and right side edges becomes narrower toward the distal end direction of the head portion 2, and a portion where the side edge of the band portion 1 is applied Means a unit side edge. Therefore, when a large number of inclined unit side edges are present intermittently (stepwise) as described above, it refers only to the unit side edge on which the band portion 1 hangs, and has a linear or gentle curved shape (for example, as shown in FIG. 15). When they exist continuously (in the shape of an arc shown), the whole is called a holding edge 8, and a portion sandwiched between the holding edges 8 is called a holding portion 7.

The entry portion 6 refers to a portion formed to be relatively wide so that the band portion 1 can be easily inserted. When the through hole 5 has a trapezoidal shape as in the present embodiment, the holding portion 7
It can be said that the entry portion 6 is provided as a part of the entry portion, and that the holding portion 7 is provided as a part of the entry portion 6.

The left and right side edges of the band portion 1 are formed in a wavy shape in which concave portions and convex portions are alternately provided in a constant shape at intervals substantially equal to the thickness of the band portion 1 as shown in FIG. The portion is formed with a receiving edge 27 cut perpendicularly to the longitudinal direction of the band portion 1, and at the tail portion 4 side of the receiving edge 27, diagonally from the head 2 toward the tail portion 4 toward the center of the band portion 1. And the cut edge is a cut edge, and the concave portion is nothing but a gap existing between the adjacent convex portions. The dimension of the receiving edge 27 is desirably set to be equal to or greater than the thickness of the band portion 1, and the interval between adjacent convex portions is desirably set to be equal to or greater than the thickness of the band portion. In addition, receiving edge 2
7 from the head 2 to the tail 4 as shown in FIGS.
If it is formed in a state where it is cut obliquely toward the center of the band 1 in the direction, the detachment prevention effect may be improved.

The binding band is constructed as described above, and surrounds the binding point of the object to be bound with the band portion 1 and is inserted into the through hole 5 from the tail portion 4 of the band portion 1 to form a loop of the binding band. By pulling the tail portion 4 to contract the loop of the binding band, the object to be bound inside the loop is tightened. The restoring force of the band 1 acts in the direction of expanding the ring, that is, in the direction of loosening the tightening, but at the same time, the restoring force acts on the inside of the through hole 5 toward the holding portion 7, and As a result, the clamping edges 8, 8 of the through holes 5 are pressed against each other (hereinafter referred to as a first operation). Further, since the both side edges of the band 1 are provided with the concavities and convexities continuously as described above, the holding edge 8 of the through hole 5 is guided by the feed edge 28 of the band 1 and hooks on the receiving edge 27 for fastening. The state is reliably maintained (hereinafter referred to as a second operation).

In addition, since the binding band has a band shape having a certain width, when a loop is formed, the extension amount between the vicinity of both side edges of the band portion 1 and the central portion sandwiched between the both side edges. Differences occur. That is, as a result of a larger amount of stretching in the vicinity of both side edges as compared with the central portion, in the surface facing the outside of the ring, FIG.
Near the 3 as opposite side edges are curved in the width direction while projecting, the clamping diene 8 of the through-hole 5, a more strongly be involved in that the accept edge 27 of the belt portion 1 (hereinafter third action Described). If the entrance 6 cannot be made large due to the size of the head 2, it is one of the desirable measures to expand the lower part of the entrance 6 as shown in FIG. 15 so as not to destroy the third effect. .

The shape of both side edges of the band portion 1 is one of preferred shapes for maintaining the fastening state, but is not limited to this shape. Even if the shape of the unevenness is not uniform, a corresponding bundling effect can be obtained. Under certain requirements, the first action and the third action are combined to provide unevenness on both side edges. Even if not provided, a sufficient fastening effect can be obtained. For example, when soft iron is used as the material and has a thickness of about 0.3 mm to 1.0 mm, the edges of the left and right side edges are crushed and are caught on the holding edges 8, 8 without providing irregularities on both side edges, and the first edge is formed. It is possible to use it according to the use in combination with the action and the third action. However, if the thickness is less than 0.3 mm, the band is too soft, so that it is difficult to obtain a practical binding effect unless the second action is used by providing irregularities on both side edges. Therefore, in giving the binding strength required for the binding band according to the present invention, it is necessary to appropriately combine the shape, material, wall thickness, width, and the like of the side edge of the band portion 1.

Therefore, another embodiment in which the shape, material, thickness, width, etc. of the side edge of the band 1 is appropriately combined is shown in FIG.
2 and FIG. The tie is made of a relatively thin resilient metal. The width of the band 1 is 5
Although it is slightly wider than the width of the entrance portion 6, the material is easily warped due to the characteristics of the material and the resilience is high. Therefore, as shown in FIG. Can be inserted. In the first place, the entrance portion 6 of the through hole 5 is determined by the width of the band portion 1.
, The binding is extremely good and it is unlikely that the binding will be released unless the side edges of the binding are broken. That is, the entry portion 6 having a width through which the band portion 1 can be inserted.
This means that the width of the entry portion 6 is not always wider than the band portion 1 and the entry portion is slightly narrower than the band portion 1 when the clamping edges 8 of the band portion 1 and the through holes 5 are elastic. This is a concept that also includes 6.

The binding band according to the present invention has a restoring force (a force acting to loosen the binding) which is present in the metal band.
Is used to obtain a strong binding force.
Therefore, if measures are taken to increase the restoring force, the binding force will be further increased. As a specific means, means for forming a large number of fine projections 52 by embossing or the like on at least one of the front and back surfaces of the band portion 1 to form irregularities,
There is a means for providing a longitudinal wavy spring portion 51 along the longitudinal direction of the band portion 1 at least near the head portion 2 of the band portion 1.

One of the sources of the restoring force of the binding band at the time of binding is a force acting to eliminate the curvature in the width direction which derives the third action. When the projections 52 are bound toward the binding object, the binding object and the binding band come into contact with the projection 52 at the center of the binding band protruding toward the binding object, and Pressure is applied. As a reaction, the force for eliminating the curvature in the width direction is concentrated at the center of the binding band, and the restoring force of the binding band is further increased because the pressing area is small, such as point contact. . Also, the projection 52
The coefficient of friction with the object to be bound is increased by
The effect of stabilizing the binding state is obtained by, for example, the portion 2 being hung on the edge of the through hole 5 on the band portion 1 side.

When the band 1 is provided with a means for providing a spring portion 51, elasticity that expands and contracts in the longitudinal direction of the binding band is given. When the band is stretched and bound by a predetermined force, a contraction force due to the elasticity is applied. The tightness improves. In addition, as a method of providing the spring portion 51, a large number of waves may be provided in a bellows shape by bending, or only one step may be provided near the head. Further, the planar shape of the wave may be V-shaped or linear in the longitudinal direction of the band portion 1. If the spring portion 51 is provided over substantially the entire area of the band portion 1 and one wave is formed over a predetermined dimension in the longitudinal direction like a V-shaped wave, a rib-like function is provided and the band portion 1 is restored. It also has the effect of increasing power.

Next, an embodiment of a binding device according to the present invention will be described with reference to the drawings. This bundling device is an apparatus main body 2 having an enclosing portion 9 surrounding three sides of an object to be bound provided at a tip end.
In order to fasten the binding band 10 curvedly loaded in a U-shape to the surrounding portion 9 along the edge of the surrounding portion 9 in an annular shape, the catching portion 3 of the binding band 10 is caught and moved on a predetermined track. The guide rod 16 is supported as described above.

As shown in FIG. 7, for example, as shown in FIG. 7, the apparatus main body 29 has opposed flat plates 30, 30 each having an arched or rectangular cutout similar to the binding band 10 at the time of loading. Aggregates 31 and 32 are interposed along both side edges of the screw and are screwed. As described above, the surrounding portion 9 is formed at the distal end portion of the device main body 29, and the aggregates 31, 3 are provided inside the surrounding portion 9.
A passage is formed in which the inner surface of the belt 2 is a sliding contact surface with which the head portion 2 and the tail portion 4 of the binding band 10 are in contact. The width of the aggregates 31 and 32 is adjusted to the width of the head 2, and the aggregate 3 with which the head 2 contacts
The sliding surface 33 of 1 is formed flat, and the aggregate 3 whose tail portion contacts
The groove 18 is formed on the second sliding contact surface 34 so as to match the width of the band 1. The flat plates 30, 30 sandwiching the sliding surfaces serve as side walls of the passage, and grooves 17, 18 are formed in which the movement of the binding band 10 during sliding is suppressed.

The hollow portion of the apparatus main body 29 also functions as a holder portion 24 capable of connecting a plurality of U-shaped curved binding bands 10 as shown in FIGS. 8 and 9, for example. If the urging means for feeding the material into the surrounding portion 9 is provided, the next banding band 10 is sequentially supplied to the front end portion of the surrounding portion 9 every time the binding is performed. The details of the biasing means are omitted because there are various known means such as a means for feeding a staple.

When the binding body 10 is connected to the holder portion 24, the binding body itself is relatively thin, so that there is a high possibility that a plurality of closely attached binding bodies are caught at once by the guide rod. Therefore, the head and the tail are provided with a gap means by a step 35 as shown in FIG. 8 so that an appropriate gap is formed between the straps loaded in the holder 24, or the middle of the strap 10 as shown in FIG. Provide a wedge-shaped cut in the part toward both ends,
The cuts are projected outward to form the claws 36, and hook holes 37 are formed on the head and tail sides of each of the claws 36, and the binding body located in front of the binding bands 10, 10 contacting back and forth. It is desirable to provide a polymerization preventing means in which the front and rear end surfaces of the binding body 10 located behind are brought into contact with the ten claws 36, 36.

A holding portion is formed at the end of the surrounding portion 9 to hold the binding band 10 fed into the surrounding portion 9. That is, a head holding unit 1 that holds the head 2 of the binding band 10 at one end facing the gap 11 surrounded by the surrounding unit 10.
2, and a tail holding portion 13 for holding the tail portion 4 of the binding band 10 is formed at the other end. The two holding portions 12 and 13 are configured such that the width of the remaining edge portions 38 and 38 existing across the notch formed in the flat plate 30 is wider than the thickness of the aggregates 31 and 32, so that the leading ends of the aggregates 31 and 32 are formed. Side walls are formed on the sides of the sliding surfaces 33 and 34 as described above, and the leading ends of the respective aggregates 31 and 32 are slid over the entire width toward the gap 11 surrounded by the surrounding portion 9. Front walls protruding from the surfaces 33 and 34 are provided as stoppers 19 and 20. In addition, in the stopper 20 of the tail holding portion 13, the tip of the catching claw 14 of the guide rod in the return state as shown in FIG. 14 is closed by the gap 11 surrounded by the surrounding portion 9 by the tip of the groove 18 of the tail holding portion 13. , And function as the tail stopper 20.

The head holding portion 12 has a guide path 21 formed behind the stopper 19 so as to allow the guide rod 16 and the band portion 1 of the binding band 10 to advance and retreat through the bottom wall of the groove 17. The tail holding portion 13 is formed behind the stopper 20 with a guide passage 22 having a size that allows the guide rod 16 to advance and retreat through the bottom wall of the groove 18. Is formed to form a hole 23 through which the band portion 1 of the binding band, which has been bound and cut, can escape.

The guide rod 16 has a catching claw 14 at the tip,
A portion of the guide rod 16 extending from the leading catch 14 to at least about the length of the band portion 1 is formed into an arc shape having a constant radius, and is provided behind the guide rod 16 to provide a support point at the center of the arc. Is provided with a support arm 39 at the center of the arc, and a support hole is provided at a portion corresponding to the center of the arc. The catching claw 14 is slightly thinner than the other portion so that only the tip of the guide rod 16 fits into the small hole 25 of the binding band 10, and the end face 40 is an inclined surface facing the front outside of the guide rod 16. I have. As described above, in the case where the symmetrical constriction 26 is provided on the left and right side edges of the tail portion 4 and the locking portion 3 is used,
At both sides of the end surface of the guide rod 16, the constriction 2 at the hook 3
Protrusions that surround the sides of the six portions may be provided.

A shaft 41 is inserted through a support hole of the guide rod 16 so as to move the guide rod 16 in a circular orbit passing through the guide paths 21 and 22 of the head holding part 12 and the tail holding part 13.
Is fixed to the surface of the apparatus main body 29 at a distance equal to the radius of the arc formed by the guide rod 16 from the guide paths 21 and 22 of the head holding part 12 and the tail holding part 13, and the guide rod 16 is moved forward and backward by lever operation. A mechanism is attached to form a binding device.

For example, as shown in FIG. 5, the outer frame 42 is slid along the apparatus main body 29, and the guide rod 16 connected to the outer frame 42 is advanced at a stroke by lever operation. The rack is connected with the guide bar that is linked to it, and the feed claw for feeding the rack is attached so that it is linked with the lever and does not catch on the rack on the return path. There is a means provided with a retaining claw to be hooked and for advancing the guide bar in a stepwise manner with the reciprocation of the feed claw by lever operation. In the latter case, the rack is always urged toward the return direction, and the feed claw and the holding claw are always urged toward the rack. At the same time, it is necessary to take measures for the holding claws to release the hooks from the rack. Although only the configuration in which the guide rod advances and retreats in a circular orbit has been described, for example, a similar mechanism can be additionally provided by using a linear guide rod 15 as shown in FIG. At this time, the surrounding portion 9 is used to suppress the exposure of the guide rod 15.
It is considered that it is desirable that the guide rod 15 is always provided so that the guide rod 15 can be stored.

The tying device according to the present invention is constructed as described above, and the guide rod is advanced by a predetermined lever operation, and the hooking part 3 of the tying band 10 holding the head 2 and the tail 4 is held at the tip. It is caught by the claws 14 and fed into the through-holes 5 of the binding band 10 to bind the reinforcing bars or the like according to the magnitude and the number of times of the force applied to the lever. Among the mechanisms for moving the guide rod forward and backward by the lever operation, a mechanism for moving the guide rod at a stretch is provided with the outer frame 4 with respect to the apparatus main body 10.
2. In the mechanism that provides a stopper that keeps the sliding stroke constant and guides the guide rod step-by-step, if the number of lever operations is determined, it will be uniform even if any operator performs the binding work. Such unity is performed.

[0031]

As described above, if the binding band according to the present invention is used, the binding is completed by a simple operation of simply pulling the tail of the band into the through-hole, so that the time required for binding at one place is extremely short. In addition to shortening, the shear strength and the binding strength are guaranteed according to the specifications of the binding band, so that the reliability is high. Further, since the fastening state can be visually checked, the fastening force can be made uniform irrespective of the arm strength of the worker if the dimensions of the belt portion to be drawn into the through hole are determined. In addition, since the twisting does not occur in the binding operation, there is no possibility of local weakening.

The use of the tying device according to the present invention makes the tying work extremely easy and shortens the construction period. In addition, since the tightening force can be controlled mechanically, the uniformity of the tying force is extremely uniform. It is easy and contributes to increase the reliability of the building.
