Technical Field

The present invention relates to a binding tool for binding objects.

Background

A binding tool is known in the past, which includes a belt having flexibility and a head having a through hole through which the belt wound around an object is inserted. Such a binding tool is generally disposable because the belt inserted into the through hole is not pulled out.

With the recent increasing awareness of environmental protection and effective use of resources, a reusable harness has been developed (see, for example, patent document 1). The binding tool described in patent document 1 can remove the belt from the head portion through a slit provided in a side surface of the head portion.

Detailed Description

Hereinafter, the binding tool 1 according to the embodiment will be described based on the drawings. The embodiments of the present invention described below are examples for embodying the present invention, and the scope of the present invention is not limited to the embodiments described below. Therefore, the present invention can be implemented with various modifications to the embodiments.

Fig. 1 is a front upper perspective view of a binding tool 1 according to the present embodiment. Fig. 2 is a front lower perspective view of the binding tool 1 of the present embodiment. Fig. 3 is a cross-sectional view of III-III of fig. 1. As shown in fig. 1 to 3, the harness 1 is composed of a strap 10 and a head 20. The binding tool 1 is made of, for example, a resin material. The binding tool 1 may be integrally formed, or the strap 10 and the head 20 may be separately formed and assembled.

In the present embodiment, the extending direction of the belt 10 is defined as the "front-rear direction", the thickness direction of the belt 10 is defined as the "up-down direction", and the width direction of the belt 10 orthogonal to the extending direction and the thickness direction of the belt 10 is defined as the "left-right direction". In fig. 1 to 3, the leading end side (downstream side in the extending direction) of the belt 10 is referred to as "front", and the base end side (upstream side in the extending direction) of the belt 10 is referred to as "rear". In fig. 1 to 3, the front side of the belt 10 is referred to as "upper" and the back side of the belt 10 is referred to as "lower". However, the combination of the above-described directions is merely an example, and is not limited thereto.

The belt 10 is a flexible belt-like member. The base end of the belt 10 is connected to the front face of the head 20, and the leading end is a free end. The belt 10 is wound around the outer peripheral surface of the object. The object may be, for example, a bundle of cables or hoses, or may be a support column and a cable or hose fixed to the support column. The cross section of the object is not limited to a circle, and may be a rectangle (angle member or the like). In the belt 10 wound around an object, the side contacting the object is referred to as the "back surface", and the opposite side is referred to as the "front surface".

The belt 10 mainly includes: a plurality of ratchet teeth 11; a plurality of ribs 12, 14, 15; and a protruding piece (mounting portion) 13. Fig. 1 to 3 are schematic views for easy description of the present embodiment, and the protruding amounts and intervals of the ratchet 11 and the protrusions 12, 14, and 15 may be different from the actual state.

A plurality of ratchet teeth 11 are provided on the surface of the belt 10 at positions spaced apart in the front-rear direction. A plurality of ratchet teeth 11 protrude upward from the surface of the belt 10 and are arranged to extend along the surface of the belt 10. A plurality of ratchet teeth 11 extend parallel to each other. The extending direction of the plurality of ratchet teeth 11 is inclined with respect to the front-rear direction and the left-right direction. More specifically, the extending direction of the plurality of ratchet teeth 11 is inclined so that the right end is located forward from the left end. The extending direction of the plurality of ratchet teeth 11 is inclined by, for example, about 45 ° with respect to the front-rear direction.

A plurality of ribs 12 are provided on the back surface of the belt 10 at spaced positions in the front-rear direction. A plurality of ribs 12 project downward from the back surface of the belt 10 and extend along the back surface of the belt 10. A plurality of ribs 12 extend parallel to the plurality of ratchet teeth 11. As shown in fig. 3, the plurality of ratchet teeth 11 and the plurality of ribs 12 are preferably arranged at positions staggered with each other in the front-rear direction.

The protruding piece 13 is provided at the front end of the belt 10. The tab 13 protrudes in the left direction from the front end of the belt 10. The thickness of the tab 13 is set to be, for example, the same as that of the belt 10. The protruding piece 13 has a plurality of protruding strips 14 formed on the front surface and a plurality of protruding strips 15 formed on the rear surface. The portions of the ridges 14 and 15 correspond to convexities of concavities and convexities, and the portions between the adjacent ridges 14 and 15 correspond to concavities of concavities and convexities. It should be noted that there may be one each of the ribs 14 and 15.

The pitch, projection amount, width, and extending direction of the ridge 14 are, for example, the same as those of the ratchet 11 provided on the surface of the belt 10. The pitch, projection amount, width, and extending direction of the ribs 15 are the same as those of the ribs 12 provided on the back surface of the belt 10, for example. However, the shape of the ribs 14 and 15 is not limited to the illustrated example.

The head 20 has a role of locking the belt 10 wound around the object, thereby maintaining the binding tool 1 in a state of binding the object. The head portion 20 is configured to be able to release the locked state of the belt 10. Thus, the binding tool 1 can be reused. The head 20 mainly includes: a top wall 21, a bottom wall 22, and side walls 23.

The top wall 21 and the bottom wall 22 are disposed opposite to each other with a predetermined gap therebetween in the vertical direction. The side wall 23 connects left ends of the top wall 21 and the bottom wall 22 to each other. As a result, the head 20 is formed with a through hole 24 surrounded by the top wall 21, the bottom wall 22, and the side wall 23. The through hole 24 is open on the front, rear, and right sides (the sides opposite to the side walls 23) of the head 20.

Further, the base end of the belt 10 is connected to the front face of the head 20 where the through hole 24 is opened. In other words, as shown in fig. 1 to 3, when the belt 10 extends straight in the front-rear direction, the extending direction of the through-holes 24 is parallel to the belt 10. The belt 10 wound around the object is inserted through the through hole 24.

On the other hand, the right side of the head 20 is not closed by the side wall. In other words, the right surface of the head 20 is opened by the slit 25. The slit 25 communicates the through hole 24 with the outside of the head 20. More specifically, the slit 25 allows the belt 10 to be inserted into and removed from the through hole 24. In the binding tool 1, the protruding direction of the protruding piece 13 and the position of the slit 25 are opposite to each other in the right-left direction. However, the projecting piece 13 may be projected in the right direction, and the slit 25 may be formed on the left side of the head portion 20.

Further, the head 20 includes: a pawl support 26, and a plurality of pawls 27. The pawl support 26 is provided below the top wall 21. The claw support 26 is inclined downward toward the front of the head 20. That is, the distance between the bottom wall 22 and the claw support 26 (in other words, the height of the through hole 24) gradually decreases toward the front of the head 20. The claw support 26 is configured to be elastically deformable in the vertical direction.

The plurality of pawls 27 are formed on the lower surface (i.e., the surface facing the through hole 24) of the pawl supporting portion 26. The pawls 27 lock the ratchet teeth 11 of the belt 10 inserted through the through-hole 24 to prevent the belt 10 from being pulled out of the through-hole 24. The number of the pawls 27 is not limited to a plurality, and may be one.

A plurality of pawls 27 project downward from the lower face of the pawl support portion 26 at positions spaced apart in the front-rear direction, and are provided extending along the lower face of the pawl support portion 26. A plurality of pawls 27 extend parallel to each other. The extending direction of the plurality of pawls 27 is inclined so that the right end is located forward of the left end.

The extending direction of the plurality of pawls 27 is parallel to the extending direction of the ratchet teeth 11 of the belt 10 inserted through the through-hole 24. Typically, the pitch, projection amount, width, and extending direction of the plurality of pawls 27 are the same as those of the ratchet teeth 11 provided on the surface of the belt 10. The extending direction of the ratchet 11 and the pawl 27 is not limited to the above example. That is, the ratchet 11 and the pawl 27 may be inclined so that the side provided with the slit 25 is located forward from the opposite side.

As shown in fig. 1, the width W1 in the left-right direction of the through-hole 24 (in other words, the distance from the right surface of the side wall 23 to the slit 25) is set to be larger than the width W2 in the left-right direction of the belt 10. More specifically, the width W1 of the through-hole 24 is set to be twice or more of the width W2 of the belt 10.

Next, a procedure of fixing the binding tool 1 to the object 2 will be described with reference to fig. 4 to 6. Fig. 4 is a perspective view showing a state where the belt 10 is wound around the object 2. Fig. 5 is a perspective view showing a state where the belt 10 is wound twice around the object 2. Fig. 6 is a diagram showing the relationship between the ratchet 11 and the pawl 27.

First, as shown in fig. 4, the user brings the lower surface of the head 20 (more specifically, the lower surface of the bottom wall 22) into contact with the outer peripheral surface of the object 2. Next, the user winds the belt 10 around the outer peripheral surface of the object 2. Next, the user inserts the belt 10 wound around the object 2 once into the through hole 24 (more specifically, between the bottom wall 22 and the claw support 26) through the slit 25. The belt 10 inserted into the through hole 24 elastically deforms the claw support 26 upward. Then, the ratchet 11 is locked to the pawl 27 by the force elastically restoring the pawl support portion 26 downward.

Here, as shown in fig. 6 (a), when the hand is released from the belt 10 inserted through the through hole 24, a force in the direction of arrow a acts on the belt 10 which is about to be elastically restored. Thus, the rear surface of the ratchet 11 is engaged with the front surface of the pawl 27, and the belt 10 moves in the arrow X direction along the pawl 27. As a result, the belt 10 is pressed against the side wall 23 and prevented from being pulled out naturally from the head 20.

Next, as shown in fig. 5, the user winds the belt 10, which has been wound around the object 2 once and passed through the through-hole 24, further around the object 2. Then, the user inserts the belt 10 wound twice around the object 2 into the through-hole 24 through the slit 25. The relationship between the ratchet 11 of the belt 10 wound for the second time and the pawl 27 of the head 20 is common to the description using fig. 6 (a). Further, inside the through-hole 24, the belt 10 wound for the first time and the belt 10 wound for the second time are disposed adjacent to each other in the left-right direction.

Then, the user repeats a series of operations of winding the belt 10 around the object and inserting the belt through the slit 25 and the through hole 24 a plurality of times (W1/W2). As shown in fig. 5, the user inserts the protruding piece 13 provided at the leading end of the belt 10 between the belts 10 wound around the object 2 (or between the object 2 and the belts 10).

Next, as shown in fig. 6 (B), when the tip of the belt 10 fixed to the object 2 is moved in the direction of arrow B, the front surface of the ratchet 11 engages with the rear surface of the pawl 27. Thereby, the belt 10 moves in the arrow Y direction along the pawl 27. As a result, the belt 10 is pulled out from the head portion 20 through the slit 25. That is, the binding tool 1 is released from binding the object 2.

According to the above embodiment, for example, the following operational effects will be effective.

According to the above embodiment, since the ratchet 11 and the pawl 27 are inclined with respect to the width direction of the belt 10, the belt 10 is prevented from being detached from the head portion 20 naturally, and the binding implement 1 can be easily detached from the object 2 by moving the tip end of the belt 10 along the pawl 27. As a result, the reusable harness 1 having a simple structure is realized.

Further, according to the above embodiment, the protrusion 12 parallel to the ratchet 11 is provided on the back surface of the belt 10, so that the ratchet 11 and the protrusion 12 are engaged (abutted) at a portion where the belt 10 is partially overlapped. As a result, the resistance of the surfaces of the belts 10 in contact with each other increases, and the binding tool 1 can be firmly attached to the object 2.

Further, according to the above embodiment, the ratchet 11 and the protrusion 12 are formed by being displaced in the front-rear direction, whereby the thickness of the belt 10 in the front-rear direction can be made uniform. As a result, in the case where the tying tool 1 is manufactured by blow molding, the occurrence of sink marks or warping of the belt 10 can be prevented. Further, the belt 10 does not have a portion with a small thickness, and therefore, the strength of the belt 10 can be prevented from being reduced.

Further, according to the above embodiment, the width W1 of the through-hole 24 is set to be twice or more of the width W2 of the belt 10, whereby the belt 10 can be wound around the object 2 as many times as possible. As a result, the objects 2 can be bound firmly.

Further, according to the above embodiment, the base end of the belt 10 is connected to the front face of the head portion 20 in which the through hole 24 is opened, whereby the belt 10 extending from the head portion 20 can be brought close in parallel to the belt 10 inserted to the through hole 24. As a result, the belt 10 can be easily made to follow the object 2, and the tip of the belt 10 can be prevented from protruding outward in the radial direction of the object 2. However, the attachment position of the base end of the belt 10 is not limited to the above example, and may be below the bottom wall 22. That is, the extending direction of the through-hole 24 may not be parallel to the belt 10.

Further, according to the above embodiment, the protruding piece 13 is inserted between the belts 10 wound around the object 2 (or between the object 2 and the belts 10), thereby making it easier to make the leading end of the belt 10 follow the object 2.

In the binding tool 1, which is assumed to be repeatedly used (in other words, the tip of the belt 10 passing through the through-hole 24 cannot be cut) with the tip of the belt 10 being made to follow the object 2, it is important to improve the aesthetic quality when binding the object 2.

[ modified examples ]

The specific configuration of the attaching portion is not limited to the protruding piece 13, and any configuration may be used as long as the leading end of the belt 10 passing through the through hole 24 can be attached to the intermediate portion of the belt 10 wound around the object 2. Fig. 7 is a front upper perspective view of a harness 1A according to a modification. The detailed description of the common points with the above embodiments is omitted, and the differences will be mainly described.

As shown in fig. 7, the harness 1A of the modification differs from the above-described embodiment in that a holding portion 16 is provided instead of the protruding piece 13. In the binding tool 1A of the modification, the protrusion 12 is omitted from the back surface of the belt 10, and the width of the through hole 24 and the width of the belt 10 are substantially the same.

The holding portion 16 is provided at the front end of the belt 10. The holding portion 16 is composed of a pair of protruding portions 16a and 16b protruding downward from both ends in the width direction of the belt 10, and a pair of holding portions 16c and 16d extending in a direction in which the leading ends of the pair of protruding portions 16a and 16b approach each other. The width of the belt 10 is smaller than the interval between the pair of protruding portions 16a and 16b and larger than the interval between the leading ends of the pair of holding portions 16c and 16 d.

The harness 1A of the modification is fixed to the object 2 by the steps described with reference to fig. 4 to 6. Then, the user elastically deforms the pair of protruding portions 16a and 16b in the expanding direction, and inserts the pair of holding portions 16c and 16d between the belt 10 wound around the object 2 and the object 2. Thereby, the intermediate portion of the belt 10 wound around the object 2 is held by the pair of protruding portions 16a and 16b and the pair of holding portions 16c and 16 d. Even with such a holding portion 16, the leading end of the belt 10 can be made to follow the object 2.

[ other modifications ]

The harnesses 1 and 1A of the present invention may have only some of the features described in the above embodiments and modifications. For example, the ratchet 11 and the pawl 27 may not be inclined (i.e., may be perpendicular) with respect to the extending direction of the belt 10. As another example, the belt 10 may not be provided with a mounting portion. As another example, the width W1 of the through-hole 24 may be smaller than twice the width W2 of the belt 10.
