  By the way, in assembling the pipe protector to the bent portion of the pipe material, first, the first clamp of the pipe protector is moved along the longitudinal direction of the pipe on the other side, and then the second clamp is moved. It is required to move along the longitudinal direction of the one side pipe. That is, since the pipe protector needs to move in two different directions, the assembly work tends to be complicated accordingly.

  Further, in the assembling work, in addition to the first working area radially outward of the one side pipe of the bent portion, the second working area radially outward of the other side pipe is required as the working space. Therefore, a large work space is required for the assembly work. However, for example, in the vehicle interior space of the vehicle, since the vehicle component parts are arranged compactly and are extremely narrow, the assembly work inside such a vehicle body may become more complicated.

  The present invention has been made paying attention to the above situation, and an object of the present invention is to assemble a pipe protector to the bent portion in order to protect the L-shaped bent portion of the pipe material. This is to make this assembling work easy.

According to the first aspect of the present invention, the bent portion 7 is engaged with each of the pipes 10 and 11 so as to straddle the one side pipe 10 and the other side pipe 11 of the L-shaped bent portion 7 of the pipe material 4. A pipe protector 14 to protect,
The pipe protector 14 has an L-shaped base 17 extending along the outermost surface 15 on the side far from the bending center 8 among the outer surfaces of the bent portions 7 in the longitudinal direction, and one end side portion of the base 17 A first clamp 22 that is integrally formed with 17a, extends along the one side pipe 10 and has a C-shaped cross section and can be elastically engaged with the one side pipe 10 through its opening 23. And formed integrally with the other end portion 17b of the base body 17, extends along the other side pipe 11 and has a C-shaped cross section, and passes through the opening 26. A pipe protector having a second clamp 25 elastically engageable with
The pipe protector is characterized in that a guide surface 28 is formed by chamfering a corner of an opening edge at an end of the opening 26 of the second clamp 25 on the side far from the first clamp 22.

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

The invention of claim 1 is a pipe protector that protects the bent portion by engaging with each of the pipes so as to straddle the one side pipe and the other side pipe of the L-shaped bent portion of the pipe material,
The pipe protector is formed integrally with an L-shaped base body extending along an outermost surface far from the center of bending, and one end side portion of the base body, of the outer surfaces of the bent portions in the longitudinal direction. The first clamp extends along the one side pipe and has a C-shaped cross section, and can be elastically engaged with the one side pipe through the opening. The first clamp is integrated with the other end portion of the base body. And a second clamp that extends along the other side pipe and has a C-shaped cross section and is elastically engageable with the other side pipe through the opening. In the protector,
A guide surface is formed by chamfering the corner of the opening edge at the end of the opening of the second clamp on the side far from the first clamp.

  For this reason, the said pipe protector can be assembled | attached with the following assembling operations with respect to the bending part in the said pipe material.

  That is, first, the first clamp of the pipe protector is positioned in the outer area of the outermost surface of the bent portion and in the work area radially outward of the one side pipe of the bent portion. At this time, in the work area, the longitudinal direction of the second clamp of the pipe protector is made to coincide with the virtual extension line in the longitudinal direction of the pipe on the other side of the bent portion. Then, the pipe protector is moved from the work area along the virtual extension line toward the bent portion, and the guide surface at the end of the second clamp is abutted against the convex bent outer surface of the bent portion. Make contact.

  Then, compared with the pipe protector in which the guide surface is not formed, in the above-described pipe protector, the convex bent outer surface of the bent portion enters more into the end portion of the second clamp. Therefore, after that, if the second clamp is moved in the longitudinal direction of the other side pipe so as to be pushed toward the other side pipe, the guide surface smoothly moves the convex bent outer surface of the bent portion. The second clamp is smoothly elastically deformed so that its opening is opened. Therefore, the second clamp is easily engaged with the other side pipe from the end side.

  Next, the first clamp of the pipe protector is moved from the working area side toward the one side pipe. At this time, the second clamp is slid in the longitudinal direction with respect to the other side pipe while the engagement state of the second clamp to the other side pipe is maintained. And if the said 1st clamp is engaged with the said one side pipe through the opening, the said assembly | attachment operation | work will be complete | finished.

  Therefore, in the assembly work of the pipe protector to the bent portion of the pipe material described above, the pipe protector is achieved by moving the pipe protector from the working area toward the bent portion in the longitudinal direction of the other side pipe. In other words, since the pipe protector needs only to move in one direction, the assembling work can be easily performed.

  Further, in the above assembling work, since one work area is sufficient as described above, the assembling work can be easily performed even in a place where the surplus space is narrow, for example, in the interior space of the vehicle body.

A pair of left and right pipe members 4 and 4 are provided. These pipe members 4 are made of metal having a circular cross section, have the same diameter, and are arranged side by side so as to extend substantially parallel to each other.

  Each of the pipe members 4 has L-shaped bent portions 7 at a plurality of locations in the middle in the longitudinal direction. The bent portion 7 includes a bent pipe 9 bent into an arc shape with a certain point as a bending center 8, a side pipe 10 linearly extending from one end of the bent pipe 9, and the other end of the bent pipe 9. And the other side pipe 11 linearly extending from the portion. The intersection angle between the one side pipe 10 and the other side pipe 11 is set to a value slightly larger than 90 °.

  A resin-made pipe protector 14 that engages with each of the pipes 10 and 11 to protect the bent portion 7 so as to straddle the one side pipe 10 and the other side pipe 11 of the bent portion 7 in each pipe material 4. Provided. The pipe protector 14 protects the bent portion 7 so as to prevent the bent portion 7 from being deformed by receiving some external force in the event of a vehicle collision. Since the pipe protectors 14 for the pipe members 4 are formed integrally with each other and have the same shape and the same size, one pipe protector 14 will be described below.

  The pipe protector 14 has an L-shaped base body 17 that extends along the outermost surface 15 on the side far from the bending center 8 among the outer surfaces of the bent portions 7 in the longitudinal direction. The base body 17 has a base body 18 that extends in an L shape along the outermost surface 15 by bending a belt-like plate, and a reinforcing rib 19 that is integrally formed on the inner surface of the base body 18. ing.

  A corner 28 of the opening edge at the end of the opening 26 of the second clamp 25 farther from the first clamp 22 is chamfered to form a guide surface 28. The guide surface 28 is formed only on one of the opening edges of the opening 26, but may be formed on both opening edges.

  1, 3, and 5, an assembling operation for assembling the pipe protector 14 with respect to the bent portion 7 of the pipe material 4 at the time of new assembly or repair of any device including the pipe material 4 will be described.

  That is, first, as indicated by a solid line in FIG. 1 and a two-dot chain line in FIG. 3, it is an outer region of the outermost surface 15 of the bent portion 7, and is the radial direction of the one side pipe 10 of the bent portion 7. The first clamp 22 of the pipe protector 14 is positioned in the outer work area. At this time, in the work area, the longitudinal direction of the second clamp 25 of the pipe protector 14 is matched with the virtual extension line in the longitudinal direction of the pipe 11 on the other side of the bent portion 7. Then, the pipe protector 14 is moved from the working area along the virtual extension line toward the bent portion 7, and the second clamp 25 has a convex bent outer surface of the bent pipe 9 of the bent portion 7. The guide surface 28 is brought into contact with the end portion (solid line in FIG. 5).

  Then, compared to the pipe protector 14 ′ in which the guide surface 28 is not formed as shown by the one-dot chain line in FIG. 5, in the pipe protector 14, the bent pipe of the bent portion 7 is located in the end of the second clamp 25. 9 convex bent outer surface enters more. Therefore, after that, if the second clamp 25 is moved A in the longitudinal direction of the other side pipe 11 so as to be pushed toward the other side pipe 11, the guide surface 28 is moved to the bent portion 7. The second clamp 25 is smoothly elastically deformed so that the opening 26 is opened by smoothly sliding on the convex bent outer surface of the bent pipe 9. Therefore, the second clamp 25 is easily engaged with the other side pipe 11 from the end side (two-dot chain line in FIG. 5).

  Next, the first clamp 22 of the pipe protector 14 is moved from the working area side toward the one side pipe 10. At this time, the second clamp 25 is slid in the longitudinal direction with respect to the other side pipe 11 while the engagement state of the second clamp 25 to the other side pipe 11 is maintained. When the first clamp 22 is engaged with the one side pipe 10 through the opening 23, the engaged state of the pipe protector 14 to the bent portion 7 as shown in FIGS. Thus, the above assembling work is completed.

In other words, since the pipe protector 14 needs only to move A in one direction, the assembling work can be easily performed.

  Further, in the above assembling work, since one work area is sufficient as described above, the assembling work can be easily performed even in a place where the surplus space is narrow, for example, in the interior space of the vehicle body.

  In addition, although the above is based on the example of illustration, the said pipe material 4 may be only one, and may be 3 or more. In addition, the extending direction of the one side pipe 10 and the other side pipe 11 of the bent portion 7 may be any of horizontal, vertical, and oblique directions, and the L-shape of the bent portion 7 may be inverted. It may be of an inclined posture. The intersection angle between the one side pipe 10 and the other side pipe 11 may be 90 °, and may be smaller or larger than this.
