Abstract

PROBLEM TO BE SOLVED: To provide a bidirectional insertion-type binding band that enables a binding operation to be performed in a dark place or a place where work can hardly be performed due to an obstacle.SOLUTION: In a binding band, two fastening teeth different from each other in an engagement direction are arranged within an insertion hole of a head; the outlet-side fastening teeth of the insertion hole are formed to be engaged in a direction in which a band part is pulled back; and additionally, a function of the inlet-side fastening teeth is suppressed by a rail provided in the band part.

Description

  The present invention relates to an improvement of a synthetic resin binding band, and in a binding band composed of a band portion and a head, the front end of the band portion can be inserted and secured before or after the insertion hole opened in the head. The present invention relates to a synthetic resin binding band.

  There are two types of synthetic resin binding bands: a fixed type that cannot be opened unless the band part is cut, and an open type that can arbitrarily remove the meshing state of the band part and the pawl provided on the head.

  The fixed mold will be described. For example, as shown in FIG. 13, generally, a head 52 is disposed at the rear end of the band portion 51 of the binding band 50. The band portion 52 has a thin tip portion for easy insertion, and the main body portion is formed with a constant width. Rails 53 are formed on both sides of the surface of the band portion 51, and meshing teeth 54 having a sawtooth cross section are continuously formed between the rails 53 (see Patent Documents 1 and 2).

  In the normal binding band 50, the entrance side of the insertion hole 55 provided in the head portion 52 and the surface of the band portion 51 are substantially flat, and the head portion 52 has a shape projecting to the back side of the band portion 51 in a side view. ing. An insertion hole 55 is opened in the head 52 perpendicularly to the band portion 51, and a stop tooth 56 is planted in the insertion hole 55 so as to be swingable with the entrance side as a fulcrum. In the pulling operation in which tension is applied to the band portion 51, a large fastening force (binding force) is generated by the engagement of the stop teeth 56.

  For tying the binding band 50, for example, when tying an object to be secured K such as an electric wire, the head 52 of the binding band 50 is held with one hand and the band part 51 is held with the other hand. The band portion 51 extending from the back side of the insertion hole 55 is gripped by a grip portion of a binding machine (not shown), and the band portion 51 is pulled into the binding machine by grasping the lever, with a predetermined tension. It is automatically cut in the vicinity of the head 52 and the lashing operation is completed.

  Now, the tying operation of the binding band 50 is usually a series of operations performed while confirming the fine work by visual inspection. Therefore, this inspection work and tying work are rarely carried out by groping, for example, the work place is not visible like a dim place such as under the floor or the backside of obstacles such as telephone poles, and it can only be done by groping. The lashing work is virtually impossible.

  The object of the present invention is a bi-directional insertion type composite having a special stop tooth that can easily look through and secure even in a place obstructed by an obstacle or in a dark place where the state of the passing work cannot be confirmed. A resin binding band is provided.

The binding band of the present invention for achieving the above object is configured as follows.
1) A head portion and a band portion extended from the central portion of the outer surface of the head portion, and an insertion hole through which the band portion can be inserted from both directions is opened in the head portion. When inserted into the band part, a pair of stop teeth that engage with the engaging teeth provided in the band part is provided, and the stop teeth mesh so that only one stop tooth is engaged according to the insertion direction of the band part. It is characterized by having different directions.
2) A head portion and a band portion extended from the center of the outer surface of the head portion, an insertion hole through which the band portion can be inserted from both directions is opened in the head portion, and the band is inserted into the insertion hole. A pair of pawls are arranged in series in the insertion direction of the band part, the band part has meshing teeth on both sides, and one snapping tooth located on the side from which the band part is pulled out is a meshing tooth of the band part (Series type).
3) A head portion and a band portion extended from the central portion of the outer surface of the head portion, and an insertion hole through which the band portion can be inserted from both directions is opened in the head portion. A pair of set teeth that engage with the meshing teeth provided on the band unit are provided above and below the insertion direction of the band unit, and only one set of upper or lower set teeth is provided depending on the insertion direction of the band unit. It is characterized by being formed to mesh (upper and lower molds).
4) The two stop teeth are arranged in a back-to-back state through slits in the insertion hole, and the width of the stop teeth is smaller than the lateral width of the insertion hole, and approaches the wall surfaces on different sides. It is characterized by being arranged (series type).
5) The member which suppresses the function of the stop tooth at the entrance side of the insertion hole among the two stop teeth is arranged on the upper and lower surfaces of the band part (series type).
6) A guide rail for holding the band portion in a predetermined position is provided on the wall surface of the insertion hole opened in the head (series type).

  The synthetic resin binding band according to the present invention has a band portion extending from the center of the surface of the head, and is formed in a T shape as a whole. Therefore, hold the band part so that the head is facing sideways, and prepare the bundling work, that is, keep away from it by inserting the band part through the insertion hole from any "left or right direction" of this head Is easy to do.

  In this way, the band part can be inserted from either side of the insertion hole on the head and the meshing teeth of the band part and the locking teeth can be engaged, so the binding work is a dark place or a place where the insertion work is difficult However, the band portion can be inserted into the insertion hole and bound and secured.

  The binding band according to the present invention does not need to confirm the state of the tip of the band part and the insertion hole of the head at all, so that it can be bound and secured in a groping state, and work efficiency can be further improved. it can.

The merit of the manufacturing process of the serial type binding band and the function as the binding band are as follows.
A. Since a pair of stop teeth with different meshing directions are arranged back to back inside the insertion hole of the head, a pair of stop teeth can be accurately formed, and a binding band excellent in lashing force can be efficiently manufactured. be able to.
B. Since one of the pair of pawls is not automatically engaged, the binding function can be exhibited even if the band portion is inserted from any side of the insertion hole.
C. With the guide rail, the band portion can be accurately passed through the insertion hole, and the meshing state between the meshing teeth and the stop teeth of the band portion can be stably exhibited.
D. In the member that suppresses the function of the pawl, a pair of pawls are arranged along the walls on both sides of the insertion hole, so that a gap is formed between the pawls. Therefore, by using this gap, a member that accurately suppresses the function of the stop tooth on the inlet side, that is, a rail provided on the side portion of the band portion or a member that exhibits the same effect is used to push down the stop tooth on the inlet side. The meshing can be prevented, and the function of the pawl on the outlet side can be sufficiently exerted.

  Hereinafter, the binding band of the embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the binding band 1 includes a band part 2 and a head part 3, and the band part 2 is extended from the center part of the outer surface of the head part 3. As shown in FIGS. 3 to 6, two sawtooth set teeth 7 a and 7 b are provided inside an insertion hole 4 opened in the head 3. These set teeth 7 a and 7 b are respectively Sawtooth-shaped teeth that exert a securing action toward the inlet side (engaged when tension is applied to the band portion 2) are formed. Therefore, the stop teeth 7a and 7b are opposite to each other, and a narrow slit 9 is provided between them.

  Two sawtooth teeth are provided, and the size thereof is determined according to the tension acting on the band portion 2 when tying. The slit 9 serves to divide the set teeth 7a and 7b back to back at the time of molding and divide the set teeth into two, but when the band portion 2 is inserted through the insertion hole 4, the set teeth 7b positioned on the outlet side or 7 a is slightly retracted by the tension of the band portion 2. At this time, it is preferable that the back stopper teeth 7a or 7b have a width that can press the back of the outlet stopper teeth 7a or 7b to assist the meshing action of the outlet stopper teeth.

  Referring to the relationship between the set teeth 7a and 7b, as shown in FIG. 3, the set teeth 7a on the inlet side (arrow S) for pushing the band section 2 of the insertion hole 4 are engaged with the meshing teeth 6b of the band section 2. There is a great feature in that it is configured to mesh with the meshing teeth 7b on the outlet side (drawing side) without meshing with the meshing teeth. The relationship between the pair of set teeth 7a and 7b is as shown in FIGS. 6 and 4. As shown in FIGS. 6 and 4, the set teeth 7a are arranged close to the right wall (bottom in the drawing), and the remaining set teeth 7b are inserted through holes. 4, the space G is formed between the side surfaces of the locking teeth 7 a and 7 b and the wall surface of the insertion hole 4. In other words, the present invention is characterized in that a pair of stop teeth narrower than the stop teeth of a general binding band is arranged on the wall surface as described above.

  A cross section of the band portion 2 is shown in FIG. 5, and meshing teeth 6a and 6b are formed on both front and back surfaces, respectively, and a wide rail 5a is disposed on the space G side of these meshing teeth 6a and 6b. A rail 5b having a width narrower than that of the rail 5a is arranged.

  That is, the rail 5a is formed on one side of the insertion hole 4 so as to be aligned with the stop teeth 7a, 7b that are biased to the wall surface, but the stop on the entrance side in the insertion direction (arrow S in FIG. 5). The teeth 7a are configured to be pressed by the wide rail 5a so as not to mesh. Further, the rail 5b formed on the side portion of the band portion 2 on the stop tooth 7b on the side from which the band portion 2 of the insertion hole 4 is drawn (exit) is formed narrow so as not to press the stop tooth 7b. Yes. Since the wide rail 5a suppresses the meshing function of the stop teeth on the entrance side of the insertion hole 4, the wide rail 5a is not limited to the structure described above. For example, the narrow rail and the rail are parallel to the rail. It may be a protruding ridge, or even a small protrusion formed in a straight line.

  FIG. 7 shows a state in which the band portion 2 is inserted into the upper surface of the guide rails 8 and 8 provided on both walls in the insertion hole 4 of the head portion 3. The state is shown in which the outlet side (back side) stop teeth 7b are engaged with each other without being engaged by being pressed by the wide rail 5b of the portion 2.

  FIG. 8 shows a cross-sectional view of the state in which the band portion 2 is inserted through the insertion hole 4 of the head 3, and referring to FIGS. 8 and 7, the bidirectional insertion type binding band according to the present invention. It will be understood that only the locking teeth 7b on the outlet side in the insertion direction S exert the securing action.

[Second Embodiment]
9 to 12 show a second embodiment, and a bidirectional insertion type binding band according to the present invention will be described with reference to these drawings.

  This binding band 1A is provided with a pair of retaining teeth 7A and 7B on the upper and lower surfaces (left and right direction in FIG. 9) of an insertion hole 4A formed in the head 3A. As shown in FIG. 12, the band portion 2A is formed with meshing teeth 6A on one side, and on the back side, two groove portions 10A are provided in the longitudinal direction in order to provide the band portion 2A with a non-slip function.

  As shown in FIG. 9, the binding band 1A shows a case where the band portion 2A is inserted into the insertion hole 4A from the arrow D (lower side) or the arrow U (upper side). When the band portion 2A is bent and inserted in the lower D direction, it engages with the upper set teeth 7B. Further, when the band portion 2A is bent to the upper side U and inserted, it engages with the lower set teeth 7A. That is, the set teeth 7A and 7B are provided in the insertion hole 4A in opposite directions, and the band portion 2A is engaged with one set tooth even if the band portion 2A is inserted from any side of the insertion hole 4A.

  Since the binding band 1A of this type has a long head 3A as compared with a normal binding band, the head 3A is elongated and the operability can be seen because members inside the insertion hole 4A can be seen. There are good features.

  Since the binding band according to the present invention is excellent in operability, it can be used in various applications, for example, as a means for organizing household accessories or securing plants for agriculture, depending on the properties of the synthetic resin.
