Abstract

PURPOSE: To smoothly draw out a band body in a diameter contracting direction by forming the projection of a harness binding clip which unitedly has a band body having a plurality of projections formed in the longitudinal direction of its inside, a lock body being inserted with the band body, and a leg body being engagingly attached to a panel side, into a triangular shape being acute-angled toward the free end side of the band body. CONSTITUTION: In the case of forming a plurality of projections 3 on the inside of a band body 1 to hold a harness, each projection 3 is formed into a right angled triangle-shape being acute-angled toward the side of a free end 1b within a domain from a perpendicularly provided leg body 7 toward the free end 1b. In the case of drawing out the free end 1b of the band body 1 from the inserting through hole 5 of a lock body 4, each acute-angled tapered face 3a of the projection 3 comes into contact with the harness side. Since the acute-angled tapered face 3a of each projection 3 comes into contact with the side of the harness H during the process of drawing out the free end 1b from the inserting through hole 5 in order to contract the diameter of the band body 1 having held the harness H, the smooth drawing-out of the band body 1 in a diameter contracting direction is assured.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a binding clip capable of binding and holding a harness wired inside an automobile and fixing it to a predetermined panel side.

[0002]

2. Description of the Related Art As a conventional binding clip of this type, there is one disclosed in Japanese Utility Model Laid-Open No. 59-13609. Although not specifically shown, the conventional binding clip is a synthetic resin integrally molded product, and has a flexible elongated band body,
A lock body that defines an insertion hole for inserting the band body therein and an elastically deformable leg body that engages with a mounting hole formed in the panel are integrally provided. Particularly, for a band body, The locking row teeth are continuously formed on the outer surface side of the harness, and a plurality of protrusions are formed at regular intervals at the central portion in the longitudinal direction on the inner surface side that holds the harness.

In actual use, after obtaining a state of holding the harness on the inner surface side of the elongated band body,
Insert the free end of the band into the insertion hole of the lock,
When the free end of the band body is pulled out from the insertion hole of the lock body, the locking claws provided in the insertion hole are engaged with the locking row teeth formed on the outer surface of the band body, and the harness is pulled out. Since the harness can be held in a bound state, the elastically deformable legs are then engaged with the mounting holes of the panel, and the harness is fixed to the panel side in the bound state. Further, under the above-mentioned harness binding state, a plurality of protrusions formed on the inner surface of the band body bite into the harness side, and when carrying or handling the harness in the bound state, the binding clip on the harness is not damaged. Therefore, it is possible to prevent the horizontal displacement and rotation.

[0004]

However, in the conventional binding clip, when a protrusion for preventing lateral displacement or rotation of the harness is formed on the inner surface of the band body, the protrusion is formed into a simple pin shape. Since it is only formed by projecting, the presence of such a pin-shaped projection is convenient for preventing lateral displacement and rotation of the binding clip,
When pulling out the free end of the band body from the insertion hole of the lock body in order to reduce the diameter of the band body holding the harness, the pin-shaped projections are connected to the harness side, especially as the band body is reduced in diameter. There is a big problem that the work of pulling out the band body is hindered by the problem of being caught by the band.

[0005]

The present invention was developed in order to effectively solve the problems of the conventional binding clip, and a plurality of projections are formed in the longitudinal direction of the inner surface holding the harness. Assuming a harness binding clip that integrally includes a band body, a lock body that defines an insertion hole for inserting the band body inside, and a leg body that is engaged with the panel side,
A configuration is adopted in which each of the above-mentioned protrusions has a triangular shape with an acute angle toward the free end side of the band body.

[0006]

Therefore, according to the present invention, since each protrusion formed on the inner surface of the band body that holds the harness has a triangular shape with an acute angle toward the free end side of the band body. , For example, in the process of pulling out the free end of the band body from the insertion hole of the lock body, even if the protrusions contact the harness side, their respective acute-angle taper surfaces contact the harness side as guide surfaces and the band body Since it is possible to ensure the smooth withdrawal of the band in the direction of reducing the diameter, it is possible to eliminate the situation in which each protrusion is caught on the harness side and the work of withdrawing the band body becomes difficult as in the conventional case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an illustrated embodiment. The binding clip according to this embodiment is also an integrally molded product of synthetic resin and is flexible as shown in FIGS. A long band body 1 having elasticity, and a lock body 4 which is continuously provided on the base end 1a side of the band body 1 and defines an insertion hole 5 with a lock claw 6 for inserting the band body 1 therein. The band body 1 is integrally provided with an elastically deformable leg body 7 hung from the outer surface of the band body 1 near the base end portion 1a, and the locking row teeth 2 are continuous to the band body 1 in the longitudinal direction of the outer surface. The plurality of protrusions 3 are formed in the central portion in the longitudinal direction of the inner surface that holds the harness at regular intervals.
The point is that the following configuration is adopted.

That is, in the present embodiment, as shown in the drawing, when forming a plurality of protrusions 3 on the inner surface of the band body 1 for holding the harness, the free end portion 1b is shifted from the vertically extending leg body 7. In order to reduce the diameter of the harness-carrying band body 1, the protrusions 3 are formed in a right-angled triangle shape having an acute angle toward the free end portion 1b side of the band body 1 within the range. When the free end portion 1b of No. 1 is pulled out from the insertion hole 5 of the lock body 4, each acute angle taper surface 3a of the projection 3 having the shape of the right triangle is used as a guide surface to contact the harness side.

In addition, in this embodiment, in addition to this, on both sides of the inner surface near the base end portion 1a of the band body 1 in which the lock body 4 is continuously provided, the protrusions 3 are in the opposite direction, that is, in the opposite direction. A configuration is also adopted in which a plurality of auxiliary protrusions 8 having a right-angled triangle shape having an acute angle toward the lock body 4 side are formed in a pair relationship. In the figure, reference numeral 9 denotes a gripping projection formed on the outer surface of the free end 1b of the band body 1 for facilitating the pulling out work, and 10 denotes a mounting hole for the panel in cooperation with the leg body 7. A pair of flange pieces for holding the hole edge of the harness body, 11 is a seat for a harness having an arc shape formed on the inner surface of the band body 1, and 12 is a housing for inserting the lock body 4 in order to allow the protrusion 3 to pass therethrough. It is a guide groove formed on the corresponding inner wall surface of the hole 5.

Therefore, also when using such a binding clip, basically, as in the conventional case, the state in which the harness H is held on the inner surface side of the long band body 1 is obtained, and the band body 1 is held. When the free end portion 1b is inserted into the insertion hole 5 of the lock body 4 and the free end portion 1b of the band body 1 is pulled out from the insertion hole 5 of the lock body 4, as shown in FIG. Since the locking claws 6 in the insertion holes 5 are locked to the locking row teeth 2 formed on the outer surface and the harness H can be held in a bound state, the legs 7 are subsequently drilled in the panel 13. When the harness H is elastically engaged with the mounting hole 14, the panel 1
Can be easily fixed to the 3 side.

However, under the present embodiment, as described above, each projection 3 formed on the inner surface of the band body 1 is formed into a right-angled triangle having an acute angle toward the free end 1b side of the band body 1. In the process of pulling out the free end portion 1b of the band body 1 from the insertion hole 5 of the lock body 4 in order to reduce the diameter of the band body 1 holding the harness H, the respective protrusions 3
Even if the cords contact the harness H side, their respective acute-angle taper surfaces 3a contact the harness H side, and it is possible to positively guarantee the smooth withdrawal of the band body 1 in the diameter reducing direction. As described above, it is possible to effectively eliminate the concern that the protrusions 3 are inadvertently caught on the harness H side and the work of pulling out the band body 1 becomes difficult.

Moreover, each protrusion 3 itself is, as shown in the drawing,
After all, it is possible to prevent the binding clip from laterally shifting or rotating with respect to the harness H by making the tip edge of the harness bite into the harness H side individually. When the surface 3a is to be rotated in one direction with the guide surface as the guide surface, the rotation of the harness H in the same direction is effectively made by the biting of the tip edge of each of the auxiliary protrusions 8 in the opposite direction described above. In any case, there is no need to worry about the careless shifting or rotation of the binding clip when carrying or handling the harness in the bound state. In addition, in order to prevent lateral displacement of the binding clip with respect to the harness H, in addition to the triangular protrusions 3 and 8, the receiving seat 11 having an arc shape is also involved.

Further, in the above-mentioned embodiment, the leg body 7 is fixed to the lock body 4.
Although the leg body 7 is provided on the side of the band body 1 separately from the above, the basic form of the binding clip itself is not limited to this. For example, the bottom surface side of the lock body 4 shown in FIG. It can be practically applied to any type of binding clip as long as it integrally includes the band body 1, the lock body 4, and the leg body 7, including the one in which the flange piece 10 and the leg body 7 are provided. Needless to say, and in the structure shown in FIG. 4, it is preferable to form the auxiliary protrusion 8 on the upper surface side of the lock body 4.

[0014]

As described above, according to the present invention, by adopting the above configuration, even when each protrusion comes into contact with the harness side when the free end of the band body is pulled out from the insertion hole of the lock body,
Since each acute-angled taper surface contacts the harness side as a guide surface, it becomes possible to positively ensure smooth withdrawal of the band body in the diameter reducing direction. You can eliminate the concern that the protrusions will be inadvertently caught on the harness and the work of pulling out the band will be difficult. Even if the protrusion is formed in a triangular shape, the tip edge of the protrusion can bite into the harness side, so that there is almost no fear that the function of preventing the lateral displacement or rotation of the binding clip with respect to the harness is impaired.
