TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the technical field of a band-type holder for binding and holding electric wires and pipes.
[0002]
[Prior art]
A band-type holder for binding electric wires, pipes, and the like, comprising a base portion fixed to a wall or the like, and a band portion inserted into the base portion, wherein the band portion has a through hole and a fitting hole. A head having claws, and a plurality of band holes are provided in a band in a row in the insertion direction of the band portion.The band portion is passed through the through hole, and the band hole is formed in the band hole. There is a closed annular band-type holding tool that is configured by fitting a fitting claw. This type of band-type holder has a base unit and a band unit which are integrated with each other and are separate from each other (for example, disclosed in US Pat. No. 3,632,071 and Japanese Utility Model Publication No. 58-26556).
[0003]
[Problems to be solved by the invention]
When the base portion and the band portion are integrated, there is an advantage that the relative position between the base portion and the band portion, that is, the relative position with the bound electric wire or the like does not change, but on the other hand, a head having a through hole and a fitting claw. Since the position is almost fixed, there is a disadvantage that workability in a narrow place is not good. On the other hand, if the base portion and the band portion are separate bodies, the position of the head can be freely changed, so workability in a narrow place is good, but the band portion may slip during binding and it may be difficult to tighten. . In other words, it was pros and cons.
[0004]
Means for Solving the Problems and Effects of the Invention
The band-type holder according to claim 1, which is a band-type holder for binding electric wires and pipes, and includes a base fixed to a wall surface and the like, and a band inserted through the base. The band portion includes a head portion having a through hole and a fitting claw, and a band portion in which a plurality of band holes are provided in a row in the insertion direction of the band portion. In a closed annular band-type holding tool constituted by inserting the fitting claw into the band hole by penetrating the band portion, the band portion is provided with an insertion hole provided in the base portion and the insertion hole of the insertion hole. A recess is provided between the distal end of the band portion and the band hole on the distal end side so as to slide through the engaging projection formed on the inner surface, and the concave portion is engaged with the engaging projection between the band holes on the other end side of the distal end. A mating engagement portion is provided.
[0005]
Since the concave portion is provided between the distal end of the band portion and the band hole on the distal end side, the band portion can be slidably inserted into the through hole provided in the base portion and the engaging projection formed on the inner surface of the through hole. it can.
In addition, since the engaging portion engageable with the engaging protrusion is provided between the band holes at the other end of the tip, the base portion and the band portion can be integrated by engaging the engaging portion with the engaging protrusion. Thus, the position of the band can be fixed, and if the band is not engaged, the relative position can be changed by sliding the band in the insertion hole. That is, it is possible to adopt the advantage in the case where the base portion and the band portion are integrated with each other, and the advantage in the case where the base portion and the band portion are separate from each other, as described for the band-type holding device of the related art. You can also.
[0006]
Since the base portion is fixed to a wall surface, a floor surface, a housing of the device, or the like, it is preferable to provide a hole or the like for using a fixing means such as a screw or a rivet. Alternatively, an adhesive or adhesive means such as a double-sided tape, or a fastener integrally molded, or a method of fixing the magnet to a base portion by using a double-sided adhesive tape to adhere to the base may be adopted.
[0007]
From the viewpoint of use and role, it is desirable to use a rigid material for the base portion and a material having flexibility and tensile strength for the band portion. Both are suitable for mass production because they can be manufactured by injection molding if made of synthetic resin. In this case, it is preferable to use an elastomer (urethane-based, ester-based, olefin-based, polyamide-based, etc.), polyethylene, or the like for the band portion.
[0008]
The band-type holder according to claim 2 is the band-type holder according to claim 1, wherein the inserted band is guided to the insertion hole along a direction parallel to the base. A parallel guide hole, and an inclined guide hole for guiding the inserted band portion to the insertion hole along a direction inclined with respect to the base portion.
[0009]
The parallel guide hole guides the inserted band portion into the insertion hole along a direction parallel to the base portion (a direction parallel to a wall surface to which the base portion is fixed), and the inclined guide hole is used to guide the inserted band portion. Is guided to the insertion hole along the direction inclined with respect to the base portion (the direction inclined with respect to the wall surface to which the base portion is fixed), so that the bundle diameter of the wires and the like to be bound is, for example, the base portion. By using the parallel guide holes when they are large enough to protrude, and by using the inclined guide holes when they are smaller than them, good binding can be achieved.
[0010]
The band-type holder according to claim 3 is the band-type holder according to claim 1 or 2, wherein the head portion of the band portion can be inserted through the band portion, but a part of the extra length is in an open state. A processing hole is provided.
When the bundle diameter of the wires and the like is small, the band is passed through the through-hole, and the fitting claw is fitted into the band hole, thereby preventing the band from falling out of the through-hole with the fitting claw as a bar. When bound as a closed loop, the tip side of the band protruding from the through hole may be long. If this extra length is left as it is, it gets in the way. Further, if the extra length is obstructed and cut off, it is not possible to cope with an increase in the bundle diameter due to an increase in the number of electric wires, for example.
[0011]
However, in the band-type holding device of the third aspect, such an excess length portion is formed in a U-turn shape and is passed through the excess length processing hole, so that this portion can be prevented from obstructing. Also, the excess length processing hole is partially open, for example, in the form of a slit, and can be expanded using this, so it is easy to extract the excess length portion from the excess length processing hole, for example, an electric wire It is possible to cope with an increase in the bundle diameter due to an increase in the number of bundles.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to examples of the present invention.
[0013]
【Example】
The band-type holder 100 (see FIG. 3) of the present embodiment includes the band portion 10 shown in FIG. 1 and the base portion 50 shown in FIG.
As shown in FIG. 1, the band portion 10 is a TPU (urethane-based elastomer) injection-molded product including a head portion 12 and a band portion 14.
[0014]
The head 12 is provided with a through hole 13 for binding. The hole shape of the through-hole 13 is substantially rectangular corresponding to the cross-sectional shape of the band portion 14, but the size is slightly larger than the cross-sectional size of the band portion 14, and the through-hole 13 passes through the band portion 14 in the longitudinal direction of the band portion 14. Can be moved relatively.
[0015]
The edge 16 of the through-hole 13 has a concave portion at the center of one long side (a non-recessed portion has a C-shape), and a fitting claw 15 stands upright in the concave portion. The upper half portion of the fitting claw 15 is curved as shown in FIG. 1B, and protrudes from the erected side to the opposite side. Since the band portion 10 is made of TPU and has a gap 17 between the edge portion 16 and the fitting claw 15, the fitting claw 15 is provided with its base as a fulcrum in a direction indicated by an arrow in FIG. It is elastically deformable along (clockwise, counterclockwise).
[0016]
Further, the head 12 is provided with an extra length processing hole 19 in line with the through hole 13. The hole shape and size of the extra length processing hole 19 are almost the same as the through hole 13, but a slit 21 is provided at the center of a portion opposite to the through hole 13, and a part thereof is opened. This is different from the through hole 13 in that Accordingly, the arm-shaped portion 23 sandwiching the slit 21 can be freely elastically deformed.
[0017]
A plurality of (21 in this example) band holes 25 are provided in a band along the longitudinal direction of the band portion 14 formed in series with the head portion 12, and most of them are provided. The band hole 25a near the head 12 is an engagement hole 25a, and an engagement portion 27 is provided between the band hole 25a and the adjacent band hole 25.
[0018]
The opening size of the band hole 25 and the engagement hole 25a is the same, but on the back surface 14a of the band portion 14, the portion between the band holes 25 and the portion from the terminal band hole 25 to the tip 14b of the band portion 14. Are concave portions 29, and the rail portions 31 located above and below the band holes 25 in FIG. 1C are relatively high (thick).
[0019]
The base portion 50 has a shape as shown in FIG. 2 and is a polyamide injection molded product.
The rear surface 51a of the substantially rectangular substrate 51 is flat to allow close contact with a flat surface such as a wall surface, and is provided with a circular mounting hole 53 for passing a fixing means such as a bolt or a screw. Further, a rectangular die hole 55 is provided, which is a hole formed by a die during injection molding.
[0020]
Two projections 57 and 59 are provided on the substrate 51, and a central opening 60 is provided between them.
The convex portion 57 is provided with an inclined guide hole 61 opening upward and a parallel guide hole 63 opening laterally. Both the inclined guide hole 61 and the parallel guide hole 63 communicate with an insertion hole 65 formed between the protrusion 57 and the substrate 51. The bottom surface 65a of the insertion hole 65 is a plane parallel to the back surface 51a of the substrate 51.
[0021]
The guide surface 61a of the inclined guide hole 61 is inclined as shown in FIG. 2B (45 degrees with respect to the bottom surface 65a in the present embodiment), and the band portion 14 is inserted from the tip end 14b along this. Then, the band portion 14 enters the insertion hole 65 from an oblique direction. On the other hand, since the portion serving as the bottom surface of the parallel guide hole 63 is continuous with the bottom surface 65a of the insertion hole 65, when the band portion 14 is inserted from here, the band portion 14 enters the insertion hole 65 in parallel with the bottom surface 65a. go.
[0022]
In a portion of the convex portion 57 adjacent to the central opening 60, a lower surface (a surface serving as a ceiling of the insertion hole 65) protrudes toward the bottom surface 65a to form an engagement protrusion 67. For this reason, the cross-sectional shape of the insertion hole 65 is formed in a concave shape by the engagement protrusion 67 (a concave portion 71). As shown in FIGS. 2B and 2D, in the sliding portion 69 on the side of the parallel guide hole 63 of the engaging projection 67, the ceiling facing the bottom surface 65a is flat, and FIG. As shown in FIG. 7, the cross-sectional shape of the insertion hole 65 at this portion is substantially rectangular.
[0023]
The dimensions of the sliding portion 69 substantially match the cross-sectional dimensions of the band portion 14 (portion where the concave portion 29 is not provided, see FIG. 1D). On the other hand, the position and the projecting shape of the engaging projection 67 are substantially aligned with the concave portion 29 of the band portion 14, and the size of the concave portion 71 from which the engaging projecting portion 67 protrudes is provided by the concave portion 29 of the band portion 14. 1 (see FIG. 1 (f)).
[0024]
Therefore, the band portion 14 can be inserted from the inclined guide hole 61 or the parallel guide hole 63 from the tip end 14b and inserted into the insertion hole 65, and at this time, the band portion 14 slides on the sliding portion 69. In the concave portion 71, the concave portion 29 slides on the engagement protrusion 67, and the rail portion 31 slides on both sides of the engagement protrusion 67.
[0025]
The bottom surface 65 a extends substantially all over the central opening 60 and reaches the die-cut hole 55. A lower surface 73 of the convex portion 59 is disposed above the mold release hole 55. The lower surface 73 is a plane parallel to the bottom surface 65a, and the interval between the lower surface 73 and the extension surface of the bottom surface 65a is substantially equal to the height of the sliding portion 69. equal.
[0026]
At a position adjacent to the protrusion 59 (on the side opposite to the central opening 60), an outlet passage 75 is provided so as to communicate with the die-cut hole 55. The outlet passage 75 is open upward on the upper surface of the substrate 51, and the outlet guide surface 75a is an inclined surface on which the side of the die hole 55 becomes lower. The outlet passage 75 has such a size that the band portion 14 can be inserted.
[0027]
Since the inclined guide hole 61 and the parallel guide hole 63 communicate with the insertion hole 65, and the insertion hole 65 communicates with the outlet passage 75 via the central opening 60 and the mold release hole 55, it is shown in FIG. As described above, a series of spaces extending from the inclined guide holes 61 and the parallel guide holes 63 to the exit passage 75 are formed, and the band portion 14 can pass through these spaces.
[0028]
Next, a method of using the band-type holder 100 will be described with reference to FIGS.
In use, the band portion 14 of the band portion 10 is inserted into the inclined guide hole 61 or the parallel guide hole 63 from the tip end 14b of the band portion 10 to be inserted into the insertion hole 65, and the tip end 14b side is drawn out from the outlet passage 75. At this time, the base unit 50 may be fixed to a wall surface or the like as an installation location, or may be fixed at an appropriate timing thereafter.
[0029]
Even when the band portion 14 is inserted through the insertion hole 65, when the engaging portion 27 is closer to the inclined guide hole 61 or the parallel guide hole 63 than the engagement protrusion 67 (see FIG. 3A), the concave portion 29 is formed. Pass under the engagement protrusion 67, the band portion 14 does not interfere with the engagement protrusion 67. Therefore, it is possible to freely move the band portion 14 forward and backward in the insertion hole 65, that is, freely adjust the protruding length on the head 12 side and the drawing length on the distal end 14b side.
[0030]
On the other hand, when the leading end 14b is pulled out and the band hole 25 adjacent to the engaging hole 25a passes below the engaging protrusion 67, the engaging portion 27 between the band hole 25 and the engaging hole 25a is engaged. It contacts the mating projection 67. If the distal end 14b side is further pulled out, the engaging portion 27 passes below the engaging protrusion 67 while being elastically deformed, and the engaging protrusion 67 fits into the engaging hole 25a and engages with the engaging portion 67. Are engaged (see FIG. 3B). In this case, the head 12 cannot be pulled out because the engagement protrusion 67 prevents the head 12 from being pulled out. Even if the tip 14b is further pulled, the member 27b on the head 12 side of the engagement hole 25a must be inserted under the engagement projection 67, so that movement in that direction is also prevented. Although it is not impossible to move the band 14 by pulling it, the band 14 is normally prevented from moving forward and backward.
[0031]
Whether the band portion 14 can be moved forward and backward or cannot be moved by the engagement projection 67 may be determined according to the installation location (environment) of the band-type holder 100 and use conditions.
Whether the band section 14 is inserted from the inclined guide hole 61 or the parallel guide hole 63 depends on the bundle diameter of the wires and tubes to be bound. If used, the parallel guide hole 63 may be used. Further, for example, the inclined guide hole 61 and the parallel guide hole 63 may be selectively used depending on the position of the head 12 selected in relation to the wall surface on which the band-type holder 100 is attached. In other words, the inclined guide hole 61 and the parallel guide hole 63 may be selected and used depending on the situation.
[0032]
The binding of the wires and the pipes is performed by passing the leading end 14b through the through hole 13 to make the band portion 10 annular and passing the wires or the like therein, or by winding the band portion 14 around the wires or the like. The distal end 14b is formed into an annular shape by passing through the through hole 13, and in any case, when the wires and the like are passed through the annular shape, and the distal end 14b is pulled, the fitting claw 15 is elastically deformed. Through the band 14.
[0033]
When the band portion 10 is pulled, it is stretched by 3 to 30% according to the pulling force, and the band portion 10 is made of an elastic material that tends to return to the original length when the pulling force is released. Is fitted into any one of the band holes 25, the leading end thereof comes into contact with the edge 16 to form a bar shape, so that the binding is not loosened. At this time, the tensile force is released, but a stress in the contraction direction remains in the band portion 10, and this acts as a tightening force to improve the binding. To release the binding, the band portion 10 may be stretched to loosen the fitting between the fitting claw 15 and the band hole 25, and then the fitting claw 15 may be removed from the band hole 25.
[0034]
When the bundle diameter is small and the extra length of the band portion 14 is too long, this portion may be folded and inserted into the extra length processing hole 19. Then the extra length will not be in the way.
As described above, in the band-type holder 100 of this embodiment, if the engagement protrusion 67 and the engagement portion 27 are engaged, the base portion 50 and the band portion 10 are integrated, and the position of the band portion 10 is changed. The band portion 10 can be slid in the insertion hole 65 if the engagement is not performed, and the relative position can be changed. That is, the advantage when the base portion 50 and the band portion 10 are integrated can be adopted, and the advantage when the base portion 50 and the band portion 10 are separate bodies can be adopted.
[0035]
The band-type holder 100 uses the parallel guide hole 63 when the bundle diameter of the wires and the like to be bundled is large enough to protrude from the base 50, for example, and uses the inclined guide hole 61 when the bundle diameter is smaller than that. By doing so, a good binding state can be obtained. Further, the inclined guide hole 61 and the parallel guide hole 63 can be selectively used depending on the position of the head 12 or the like.
[0036]
When the bundle diameter of the wires and the like is small and an excess length is formed on the end 14b side of the band portion 14, the excess length portion is formed into a U-turn and passed through the excess length processing hole 19. Long processing can be performed, and the extra length can be avoided. Further, since the excess length processing hole 19 is partially opened as a slit 21, the excess length processing hole 19 can be widened by using this, so that the excess length portion is separated from the excess length processing hole 19. It is easy to pull out, and it can cope with, for example, an increase in the number of electric wires and an increase in bundle diameter.
[0037]
As described above, the embodiments of the present invention have been described according to the examples. However, it is needless to say that the present invention is not limited to such examples, and can be variously implemented without departing from the gist of the present invention.
