DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 3 are views showing a first embodiment of a binding band according to the present invention, and this embodiment corresponds to the invention described in claims 1 to 3. First, the configuration will be described.

In FIGS. 1 and 2, reference numeral 11 denotes a binding band, and the binding band 11 is continuous with a band portion 13 having saw-toothed teeth 12 continuous in one side in an extension direction and a base end portion of the band portion 13. And a plate-shaped portion (locking portion) 14 integrally formed so as to extend in a flat plate shape on the side opposite to the extension direction, and the band portion 13 is covered by the flexibility of the molding material. The plate-shaped portion 14 is formed thin so as to be deformed along the outer surface of the binding member 15, and conversely is formed thick so as to limit the deformation. The plate-shaped portion 13 has insertion holes 16 through which the bent band portion 13 can be inserted at a plurality of positions in the extending direction.
They are arranged side by side so that the insertion position (spacing) from the base end can be changed.
Locking claws 17 that mesh with and lock to the serrated teeth 12 of 13 are provided. The teeth 12 and the locking claws 17 are formed so that the tooth surface shapes that mesh with each other are different from each other in the insertion direction of the band part 12, and when the band part 13 is inserted, the locking claws do not mesh. 17 swings to allow the movement of the tooth 12, and in the opposite direction, the tooth 12 and the locking claw 17 mesh with each other to restrict the movement of the band portion 13 and lock (lock) it.

Next, the binding by the binding band 11 will be described together with the action with reference to FIG. In the present embodiment, a case will be described in which, as the member to be bound 15, a plurality of electric wires 15a that are connected in parallel are bound together to bind the FFC. First, the binding band 11 is placed in a state where the tooth 12 side is the back surface, and the FFC 15 is aligned and placed at a position where one side is substantially aligned with the end of the plate-shaped portion 14. Next, the band portion 13 is bent and inserted into the insertion portion 16 at a position corresponding to the width of the FFC 15. Next, the band portion 13 is further pulled out (inserted) from the insertion portion 16 so that the teeth 12 are engaged with the locking claws 17 and locked to bind the FFC 15 together. After this, the FF of the plate-shaped portion 14
The excess band portion 13 protruding from the back side of C15 is cut, and this binding work is completed. When the band portion 13 is pulled out from the insertion portion 16, it is sufficient that the plate portion 14 is not deformed. At this time, the FFC 15 has the plate-shaped portion 14 with the one surface side as it is.
While being in contact with the flat surface, the band portion 13 is tightened and bound by an appropriate force.

As described above, in this embodiment, the FFC is used.
The FFC 15 can be bundled by being clamped between the band portion 13 and the plate-shaped portion 14 while keeping the flat plate shape without the 15 being rolled up. At this time, the band portion 13 can be inserted into the insertion hole 16 at a position corresponding to the width of the FFC 15 to engage and lock the teeth 12 and the locking claws 17, so that various widths, thicknesses, number of sheets, etc. The FFC 15 can be bound, and the binding band 11 can be commonly used for other FFCs.

Further, since the FFC 15 can be bound without being deformed, it is possible to control the binding position and the binding dimension. In addition, the flat member of the FFC15 to be bound
Instead of the wire harness 15, when a wire harness or the like whose cross-sectional shape is deformed is bound, a part thereof can be bound along the plate-shaped portion 14. Further, as another aspect of the present embodiment, as shown in FIG. 4, the plate-shaped portion 14 may be a plate-shaped portion 24 having a thicker wall. With such a configuration, the strength of the plate-shaped portion 14 can be increased, and as shown in FIG. 5, the band portion 13 is pulled out too much from the insertion portion 16 and the plate-shaped portion 14 bends to deform the FFC 15. It is possible to prevent the binding from becoming incomplete.

Further, on the back surface side of the binding member 15 of the plate-like portion 14,
As shown in FIG. 6, by forming at least one rib 25 (two in the figure) extending in the longitudinal direction, the plate-shaped portion 14 can be formed without increasing the thickness of the plate-shaped portion 14. Strength can be increased. Further, although not shown in the drawing, a plurality of band portions 13 are provided and the insertion holes are correspondingly provided.
By arranging 16 in parallel, it is possible to restrict the FFC 15 from being displaced and oblique to the binding band 11, which is effective when fixing the binding band 11. Further, at this time, the banding width can be made finer by shifting the positions of the insertion holes 16 in the extending direction and arranging them side by side for each band portion 13.

When binding a wire harness whose cross-sectional shape is deformed in place of the bound member 15 of the FFC 15 having a flat plate shape, the plate-shaped portion 14 has an irregular shape on the bound member 15 side. It can also be bound in a cross-sectional shape. Next, FIG. 7 is a view showing a second embodiment of the binding band according to the present invention, and this embodiment corresponds to the inventions described in claims 1 to 3. Since the present embodiment is applied to the above-described first embodiment, the same components will be denoted by the same reference numerals, and the description thereof will be omitted to describe the characteristic portions.

In FIG. 7, reference numeral 26 is a flexible wall.
Is formed by extending one end surface of the plate-shaped portion 14 on the base end side of the band portion 13 toward the back surface of the tooth 12, and bending the band portion 13 by the flexibility of the molding material like the band portion 13. In this case, it is formed thin so as to be deformed along the outer surface of the bound member 15. In this embodiment, in addition to the effects of the above-described embodiment, one side of the FFC 15 can be easily aligned with the end of the plate-like portion 14 by the wall 26 during bundling work and can be dropped (displaced). It is possible to prevent the FFC 15 from slipping and tilting with respect to the binding band 11 due to the holding property that the wall 26 wraps after binding, which is effective when fixing the binding band 11 or the like. Is.

Next, FIG. 8 is a view showing a third embodiment of the binding band according to the present invention.
Corresponds to the invention described in (1). It should be noted that the present embodiment can be applied to both the first and second embodiments described above, and the same reference numerals are given to the same configurations, and the description thereof will be omitted to describe the characteristic portions. In FIG. 8, 34 is a plate-shaped part,
34 is formed so as to be curved in the direction of the back surface with respect to the teeth 12 of the band portion 13, and due to the flexibility of the molding material, the band portion during binding is formed.
The flat surface can be maintained by pulling out 13 from the insertion portion 16.

In this embodiment, in addition to the effects of the above-described embodiment, the plate-shaped portion 34 can be deformed from a curved shape to a planar shape so that the members to be bound 15 can be bound.
Due to the force of the plate portion 34 to return to the curved shape, that is, the force to bend in the direction of the bound member 15, the bound member 15 can be tightened and tightly bound to the band portion 13.

[0021]

According to the first aspect of the present invention, a rigid locking portion formed so as to follow a desired outer surface shape when binding the members to be bound is bound with the members to be bound in contact with the outer surface. Therefore, the cross-sectional shape of the member to be bound remains as it is,
Alternatively, they can be bound in a desired shape. Therefore, the flat plate or the deformed bound member can be bound as it is, and the deformed bound member (for example, a bundle of filaments) can be transformed into the shape of the rigid locking portion for binding.

According to the second aspect of the present invention, since the members to be bound are bound in the state of being in contact with the flat surface of the rigid locking portion, at least a part of the binding cross-section can be linearly bound. A flat plate-like member to be bound such as an FFC or an FPC (Flexible Print Circuit) can be bound without being deformed. According to the third aspect of the present invention, since the binding can be performed with the binding width according to the size (for example, the width) of the bound members, they can be commonly used regardless of the size of the bound members.

According to the fourth aspect of the present invention, the rigid locking portion can be deformed from the curved shape to a planar shape to bind the members to be bound together. The binding member can be bound more firmly.
