Description

The present invention relates to a temporary holding holder for a hose clamp that temporarily holds the hose clamp to the hose.

Conventionally, when connecting automobile pipes with a hose, a flexible hose is placed on the outer circumference of the end of the pipe-shaped pipe, and the hose outer circumference is further tightened with a hose clamp to form a pipe. The method of fixing the hose is widely used. Since it is necessary to increase the diameter of the hose clamp when covering the outer circumference of the hose, a hose clamp equipped with a holder for holding the hose in the expanded state in advance may be used. Then, after positioning the hose clamp in the expanded diameter state at a predetermined position in the axial direction of the hose, the pipe is inserted, but the hose clamp is misaligned during the work process or during the hose installation before the work. There were many cases where it was lost. Therefore, a structure is used in which the hose clamp is temporarily held by the hose.

As the above structure, for example, in Patent Document 1 below, a clip body having a first standing piece and a second standing piece at both ends in the circumferential direction, and a substantially U-shaped frame-shaped holder for holding the clip body in an enlarged diameter state are used. A hose clip (hose clamp), a clip holding part that holds the clip body from the outer peripheral side, a detent part that bites into the outer peripheral surface of the hose, and a detent part that locks on the hose end face in the axial direction. A hose clip with a positioning tool is described, which comprises a positioning tool integrally provided with a hook portion for preventing slippage. The clip holding portion has a substantially semicircular frame shape, and a hook-shaped locking protrusion is provided on the inner circumference thereof. Further, the detent portion has a substantially annular shape and is continuously provided with a clip holding portion, and a plurality of biting protrusions are provided on the inner circumference thereof.

Then, with the clip body expanded in diameter, the holders are attached to the first and second standing pieces, and then the clip body is arranged from the radial direction with respect to the clip holding portion having a substantially semicircular frame shape. Then, the hose clip is positioned and fixed to the positioning tool by locking the locking protrusion of the clip holding portion to the triangular window formed in the clip body. After that, the positioning tool is arranged on the outer circumference of the hose, and the biting portion of the detent portion is made to bite into the outer circumference of the hose, so that the positioning tool is restricted in rotation via the detent portion, and the pipe is inserted into the hose in that state. Then, by removing the holder from the first standing piece and the second standing piece of the clip body, the diameter of the clip body is reduced, and the hose and the pipe are tightened and fixed.

Japanese Unexamined Patent Publication No. 2000-249274

In the invention of Patent Document 1, as described above, the clip main body is arranged from the radial direction of the clip holding portion having a substantially semicircular frame shape, and the clip main body is held by the clip holding portion. Therefore, the circumference of the clip holding part cannot be lengthened (if it is longer than a half circle, it is difficult to arrange the clip body from the radial direction of the clip holding part).

Engagement portions 34, 34 having ridges are provided, respectively. As shown in FIG. 4B, these pair of engaging portions 34, 34 face each other with the bottom surface 71b of the tab main body 71 in a state where the tab main body 71 is accommodated in the accommodation space 31 of the accommodation portion 20. It is designed to be placed. Therefore, when the accommodating portion 20 is directly pinched without pinching the knob portion 75 of the tab 70 and pulled toward the outer diameter direction of the hose 1 as shown by the arrow A in FIG. 4A, or the tab When the accommodating portion 20 is picked and pulled toward the outer diameter direction of the hose 1 when the knob portion does not exist in the first place, the engaging portions 34 and 34 have diameters with respect to the bottom surface 71b of the tab body 71. They are engaged in each direction (here, the outer diameter direction) (see FIG. 4B). That is, in this case, the engaging portion 34 is engaged with the tab 70 in the outer diameter direction of the hose 1. If the bottom wall 29 is not provided with the engaging portion 34, the outer surface of the bottom wall 29 engages with the bottom surface 71b of the tab body 71 when the accommodating portion 20 is picked and pulled in the hose outer diameter direction. The bottom wall 29 itself becomes an "engagement portion".

Further, the "engaging portion" may have the following configuration. For example, a convex portion is provided on either one of a predetermined location on the inner surface of the side wall of the accommodating portion or the outer surface of the tab body of the tab, and a concave portion into which the convex portion enters is formed on either one. .. Then, when the tab or the accommodating portion is picked and pulled in the outer diameter direction of the hose, the convex portion engages with the inner surface of the concave portion. That is, the convex portion or the concave portion on the inner surface of the accommodating portion forms the "engaging portion" in the present invention.

When the tab body 71 of the tab 70 is housed in the housing portion 20 of the temporary holding holder 10 and the tab 70 moves in the inner diameter direction of the hose 1, the bottom surface 71b of the tab body 71 is engaged.
