Description

  The present invention relates to a tube clip that is assembled to two pipe members that are piped adjacent to each other.

  In automobiles (vehicles), two parallel or non-parallel (non-parallel) piping members that form a pair (pair) along the panel surface of the vehicle body are used. A typical example is a brake pipe that passes under the floor of the vehicle body.

  Such a pair of piping members is required to prevent interference with the vehicle body member.

  As a countermeasure, conventionally, a single C-shaped clip member is held at a predetermined position of each pipe member, and the base side of the clip member is interposed between the pipe member and the vehicle body member (floor panel, etc.). Thus, the piping member is held so as not to interfere with the vehicle body member.

  By the way, in a factory for assembling a car body, an operator who does not have sufficient skills may be engaged in work.

  The operation of assembling the clip member as described above to two adjacent piping members is often performed by such an operator.

  However, in a structure in which separate clip members are individually attached to the piping members, forgetting to attach the clip members may occur. In many cases, a tube clip is attached to one piping member, but forgetting to attach the tube clip to the other piping member.

  Moreover, since the tube clip attached to the piping member only fits to the outer periphery of the piping member, when the vibration is received from the vehicle body, the entire tube clip rotates around the piping member or the axis of the piping member. Or shift in the direction. For this reason, the tube clip receives the behavior at this time, and may accidentally come out of the piping member, which may impair the original function.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a tube clip in which the clip portion attached to two piping members is prevented from moving in the rotational direction and the axial displacement of the piping member while preventing forgetting to attach the clip portion. There is.

In order to achieve the above object, the invention according to claim 1 is a pair of clip portions formed in a prismatic shape having pipe holding portions that can be held by two pipe members, and these clip portions. A tube clip constituted by a flexible connecting part that connects the clip part before the other pipe member mounting so as to hang down by its own weight when one clip part is attached to the piping member between them.

  With this tube clip, when the operator only attaches one clip part to one piping member, it is visually confirmed that the other clip part has not yet been attached from the state of the other clip part hanging down. Recognized. As a result, the worker is prompted to attach the other clip portion, and the prevention of forgetting to attach the clip portion is urged. Moreover, when the tube clip is attached to two piping members, even if one of the clip portions rotates around the piping member or shifts in the axial direction of the piping member, the movement of the tube clip does not occur. Since it is restrained by the clip portion held by the remaining piping member, unnecessary removal of the clip portion can be prevented.

In addition to the above-mentioned object, the invention according to claim 2 further includes a pair of clip portions so that the two pipe members arranged in various arrangements can be held while suppressing generation of reaction force as much as possible. For this, a configuration is adopted in which one side portion in the grip direction of each clip portion is connected by a substantially single string-like flexible member.

In addition to the above object, the invention described in claim 3 has a structure in which the clip portion is made of a soft member so that generation of a hitting sound when the clip portion is used as a spacer is suppressed.

  According to the first aspect of the present invention, it is possible that the other clip portion is not yet attached at a glance due to the drooping of the other clip portion that occurs when only one clip portion is attached to one piping member. I understand, and I can prevent forgetting to attach the clip part.

  Moreover, after holding the two piping members with the tube clip, even if one clip portion rotates around the piping member or shifts in the axial direction of the piping member due to vibration applied from the outside, etc. Since the clip part currently hold | maintained at the remaining piping member suppresses the movement, useless extraction of a clip part can be prevented.

According to the second aspect of the present invention, in addition to the above-described effect, the holding force required in many arrangement forms can be achieved while suppressing the generation of a reaction force that causes removal of the clip portion using a pair of clip portions. Two piping members adapted to the way can be held.

According to invention of Claim 3 , in addition to the said effect, generation | occurrence | production of the hitting sound when using it using a clip part as a spacer can be prevented.

[First Embodiment]
Hereinafter, the present invention will be described based on a first embodiment shown in FIGS.

  FIG. 1 shows a tube clip 10 that holds, for example, a pair (two) of small-diameter brake piping members 2 and 3 (corresponding to the two piping members of the present application) passing under a floor panel 1 of an automobile (vehicle). FIG. 2 shows a structure viewed from the different direction (arrow A), and FIG. 3 shows a side sectional view taken along the line BB in FIG.

  The brake piping members 2 and 3 are installed immediately below the floor panel 1 while adjoining in a non-parallel state, for example. Specifically, for example, one brake piping member 2 is arranged below the floor so as to extend linearly along the longitudinal direction of the vehicle body 4, and the other brake piping member 3 is inclined, for example, against the brake piping member 2. The vehicle is placed under the floor in an inclined posture so as to approach the vehicle rearward. 1 and 2 indicate the inclination of the brake piping member 3 arranged in parallel.

  Here, the brake piping members 2 and 3 are thin and long (cross over the front and rear wheels of the vehicle body), and also have bent portions (not shown) to follow each part of the vehicle body, so that when installing Due to this work (assembly work), large and small variations occur in each part of the brake piping members 2 and 3. For this reason, the dimension (interval) of each part between brake piping members 2 and 3 varies.

  On the other hand, the tube clip 10 is made of, for example, a soft member shown in FIG. The structure of the tube clip 10 will be described. Reference numerals 11 and 12 in FIG. 4 denote clip portions. Each of the clip portions 11 and 12 is formed of, for example, a short prismatic clip body 14 having a pipe holding portion 13. Specifically, the pipe holding portion 13 includes a piping storage space portion 16 formed so as to penetrate along the axial center portion of the clip body 14, and an entrance / exit formed on one surface of the rectangular surface of the clip body 14. 17, a relay passage 18 (shown only in FIGS. 3 and 4) that relays from the doorway 17 to the space 16, and a pair of holding hook portions 19 formed on both wall surfaces of the passage 18. And is configured. That is, as shown in FIG. 1 to FIG. 3, when the brake piping member 2 or 3 is pushed into the space portion 16 from the doorway 17 as shown in FIGS. The brake piping member 2 or 3 in the space portion 16 is gripped by the tip end portion of the hook portion 19 so as not to escape to the doorway 17.

  Moreover, the end wall part 14a formed in the clip main body 14 on the opposite side to the entrance / exit 17 is a part utilized as a spacer part. Specifically, the clip portions 11 and 12 are provided between the brake piping members 2 and 3 that are required to prevent interference and other members disposed around the brake piping members 2 and 3, in this case, between the brake piping members 2 and 3 and the floor panel 1. When the end wall portion 14a is interposed, the clip portions 11 and 12 can be used as spacers for separating the brake piping members 2 and 3 from the floor panel 1.

  The clip portions 11 and 12 have the same structure, and have a pair structure suitable for holding the brake piping members 2 and 3.

  Further, the clip portion 11 and the clip portion 12 are connected to each other by a single string-like flexible resin member 21 as a flexible connecting portion. Specifically, the string-like resin member 21 is formed by injection molding performed integrally with the clip portions 11 and 12, between the side surface center on one side of the clip portion 11 and the side surface center on one side of the clip portion 12. A single flexible string-like resin portion (small diameter) is formed between them. With this flexible resin member 21, when the tube clip 10 is attached with one of the clip portions 11 and 12 to one of the brake piping members 2 and 3, as shown in FIG. The clip part before mounting | wearing sags by the dead weight of the part 12, and is attached. That is, when only one of the clip portions 11 and 12 is attached to the brake piping member by the flexible resin member 21, the clip portion before the attachment is suspended by its own weight. This behavior can be obtained even with a string structure in which a plurality of extremely thin resin materials are brought together, as long as the resin member is substantially flexible.

  The length dimension of the flexible resin member 21 is set to a dimension necessary to absorb the dimensional variation generated between the brake pipe members 2 and 3, and the distance between the piped brake pipe members 2 and 3 is determined. Even if it fluctuates like this, it is structured so that it can be mounted between both brake piping members 2 and 3. In other words, the resin member 21 holds the two brake pipe members 2 and 3 and brakes the two (a pair of) clip portions 11 and 12 while following the variation occurring between the brake pipe members 2 and 3. The interval between the piping members 2 and 3 can be regulated.

  Using the tube clip 10 configured in this way, for example, in the assembly line of the vehicle body 1, for example, two brake piping members 2 and 3 arranged in parallel as shown in FIGS. Suppose that it is held under the floor so as not to interfere with the floor panel 1.

  At this time, the operator first holds one of the clip portions 11 and 12 of the tube clip 10, for example, the clip portion 11, and connects the entrance / exit 17 of the clip portion 11 to one of the brake piping members 2 and 3, for example, the brake piping member. 2 is inserted into a pipe portion at a predetermined position to be a held portion. When the pipe part is accommodated in the space part 16, the hook part 19 prevents the pipe part and the clip part 11 is held (gripped) by the pipe part. Similarly, the remaining clip portion 12 is also attached to the remaining brake piping member 3. Next, for example, the brake pipe members 2 and 3 are fixed below the floor while the end wall portions 14a of the clip portions 11 and 12 are interposed between the brake pipe member 2 and the lower surface of the floor panel 1 (pipe holding to prevent interference). ). As a result, the brake piping members 2 and 3 are held as shown in FIGS.

  It is assumed that the clip portion 12 (one side) is forgotten to be attached due to some factor during the operation at this time.

  At this time, the tube clip 10 is in a state where only one clip portion 11 is attached to the brake piping member 2 as shown in FIG. The resin member 21 that is bent by its own weight 12 hangs downward from the brake pipe member 2. The state of the clip portion 12 is conspicuous because it is significantly different from the state of the attached clip portion 11 and the surrounding brake piping members 2 and 3 (a state not seen elsewhere). Therefore, it can be discovered (recognized) at a glance that the clip portion 12 is not yet attached.

  Therefore, in the subsequent work, if the remaining clip portion 12 is assembled to the brake piping member 3 that has not been mounted, the holding state of the regular brake piping members 2 and 3 as shown in FIG. Forgetting to attach the clip portion 12 can be prevented.

  Moreover, since the clip portions 11 and 12 are connected to each other by the resin member 21, after the two brake piping members 2 and 3 are held by the tube clip 10, one of them is caused by vibration accompanying traveling. The clip portion 11 (or 12) rotates around the brake piping member 2 (or 3) as indicated by the arrow X in FIG. 1, or the brake piping member 2 ( Alternatively, even if there is a deviation in the axial direction of 3), the clip portion 12 (or 11) held by the remaining brake piping members 2 and 3 suppresses (regulates) the movement of the clip portions 11 and 12. Unnecessary removal (disconnection) can be prevented. In particular, in the case of the piping in which the brake piping members 2 and 3 are arranged in parallel as in the present embodiment, the progression of the axial displacement of the clip portions 11 and 12 uses the tension of the resin member 21 (regulation by the resin member 21). Can be prevented.

  In addition, since the resin member 21 has a structure having a length dimension necessary to absorb the dimensional variation between the brake pipe members 2 and 3, the distance between the two brake pipe members 2 and 3 arranged in parallel is the brake member. Even if the pipe members 2 and 3 may vary in the assembling work, the variation can be allowed and the brake pipe members 2 and 3 can be held within a desired allowable interval. Therefore, within the allowable interval, there is an advantage that one type of tube clip 10 can be used in many places with variations.

  Further, since the resin member 21 has a structure that is connected by a single flexible string-like resin portion, the resin member 21 acts on the clip portions 11 and 12 holding the brake piping members 2 and 3. The generation of reaction force that is a factor is suppressed, and a highly reliable retention can be promised. In particular, the string-like resin member 21 has a structure for connecting the side portions in the gripping direction of the clip portions 11 and 12 to each other, so that the brake piping member arranged in a state where one side is inclined as in the present embodiment. In addition to being easily applicable to the second and third embodiments, it is possible to adapt to the holding methods required in many arrangement forms as described in other embodiments described later.

  Of course, since the clip parts 11 and 12 are formed of a soft member, when the clip parts 11 and 12 are used as spacers, the generation of hitting sound with the floor panel 1 (other members) can be suppressed.

  In this embodiment, an example in which two piping members are held under the floor with a tube clip has been described. However, the present invention is not limited to this, and a tube clip having the same structure is used, for example, as described below, as shown in FIG. Other embodiments such as the second embodiment, the third embodiment shown in FIG. 7, the fourth embodiment shown in FIG. 8, the fifth embodiment shown in FIG. 9, and the sixth embodiment shown in FIG.

That is, an example is shown in which the tube clip 10 is gripped from different directions between the piping members 32 and 33 having variations.

  Even in such a usage pattern, the reaction force that causes the clip portions 11 and 12 to be removed from the piping members 32 and 33 does not act on the clip portions 11 and 12 by the string-like resin member 21.
