(Operation of sealing pump-up device)
Next, an operation procedure for repairing the punctured tire 100 using the sealing device 10 of the present embodiment will be described.

  As shown in FIG. 1, first, when a puncture occurs in the tire 100 (see FIG. 4), the user removes the housing 16 from the storage space of the vehicle, and the power switch 82 and the pressure gauge 84 are moved upward. The housing 16 is placed on the road surface or the like so as to face, the lid 78 is opened, and the storage chamber 76 is opened. At this time, since the manual is attached to the back surface of the lid 78 that is opened, the user can work while sequentially checking the manual.

  Next, the user takes out the liquid unit 70 stored separately from the housing 16 from the storage space of the vehicle. A joint hose 54 is connected in advance to the gas-liquid supply pipe 50 of the injection unit 20 of the liquid agent unit 70, and is wound around the surface of the liquid agent container 18. The joint hose 54 is removed from the surface of the liquid container 18, and the valve adapter 56 of the joint hose 54 is connected to a tire valve (not shown) of the tire 100.

  Further, the user takes out the power cable 14 stored in the storage chamber 76 from the storage chamber 76, inserts the plug 15 into a socket (not shown) of a cigarette lighter installed in the vehicle, and starts the engine of the vehicle. Thereby, electric power can be supplied from the vehicle battery (DC 12 V) to the drive circuit of the compressor unit 12.

  Next, as shown in FIG. 6, the injection unit 20 is attached to the opening device 60 with the injection unit 20 facing downward. As a result, as shown in FIG. 7, the entire insertion portion 62 is inserted into the piercing tool insertion hole 44, and the aluminum seal 26 is pierced (opened) by the distal end portion 64.

  Here, when the injection unit 20 is to be attached to the opening device 60, the first claw 94A is elastically deformed outward when it crosses the edge of the leg portion 36 in the short direction, and is widened by an interval between the first claw 94A. Thus, when the first claw 94A passes through the edge of the leg portion 36 in the short direction, both the first struts are restored. As a result, the first claw 96 </ b> A is caught on the edge of the leg 36 in the short direction.

  Further, the second claw 96A is inserted into the through hole 38 of the injection unit 20 and is caught by the edge of the through hole 38, the aluminum seal 26 is pierced by the distal end portion 64 of the insertion portion 62, and the distal end portion 64 becomes the liquid agent container. The state of intrusion into 18 is maintained. At this time, the O-ring 68 provided in the insertion portion 62 contacts the inner surface of the breaker tool insertion hole 44 and seals the breaker tool insertion hole 44. Thereby, it is suppressed that the fluid leaks outside from the breaker tool insertion hole 44.

  When the aluminum seal 26 is pierced, the sealing agent 32 in the liquid container 18 flows out to the pressurized liquid supply chamber 40 through the hole 28 opened in the aluminum seal 26. When the power switch 82 is turned on and the compressor unit 12 is operated, the compressed air generated by the compressor unit 12 is supplied into the liquid container 18 through the air passage 92. When the compressed air is supplied into the liquid agent container 18, the compressed air floats upward in the liquid agent container 18 to form a space (air layer G) on the sealing agent 32 in the liquid agent container 18.

  The sealing agent 32 pressurized by the air pressure from the air layer G is pushed out into the pressurized liquid supply chamber 40 through the hole 28 formed in the aluminum seal 26. Then, the sealing agent 32 in the pressurized liquid supply chamber 40 is supplied into the pneumatic tire 100 through the joint hose 54. Thereafter, when all the sealing agent 32 is supplied to the tire 100 from the pressurized liquid supply chamber 40 and the joint hose 54, the compressed air is supplied to the tire 100 via the liquid agent container 18, the pressurized liquid supply chamber 40, and the joint hose 54. Supplied in.

  Next, when it is confirmed by the pressure gauge 84 that the internal pressure of the tire 100 has reached the specified pressure, the user stops the compressor unit 12 and removes the valve adapter 56 from the tire valve (not shown).

  The user travels preliminarily for a certain distance (for example, 10 km) using the tire 100 into which the sealing agent 32 has been injected within a certain time after the completion of the inflation of the tire 100. As a result, the sealing agent 32 is uniformly diffused inside the tire 100, the sealing agent 32 is filled in the puncture hole, and the puncture hole is closed.

  After the preliminary run is completed, the user re-measures the internal pressure of the tire 100, reconnects the valve adapter 56 of the joint hose 54 to the tire valve as necessary, and restarts the compressor unit 12 to bring the tire 100 into the specified internal pressure. Pressurize until. Thereby, the puncture repair of the tire 100 is completed, and the tire 100 can be used to travel at a certain speed or less (for example, 80 km / h or less) within a certain distance range.

  By the way, in this embodiment, as shown in FIG. 3 and FIG. 8A, the groove portions 102 and 104 are formed in the liquid agent container 18, and the joint hose 54 is fitted into the groove portions 102 and 104. The liquid agent container 18 is wound around the surface.

  That is, the joint hose 54 can be stored together with the liquid container 18, and when the joint hose 54 is used, the joint hose 54 wound around the surface of the liquid container 18 is simply removed from the grooves 102 and 104. Is simple.

  Further, since the joint hose 54 is connected to the gas / liquid supply pipe 50, it is not necessary for the user to attach the joint hose 54 to the gas / liquid supply pipe 50, and there is a problem such as leakage of the sealing agent 32 due to poor connection of the joint hose 54. Does not occur. Furthermore, since a separate member for winding the joint hose 54 around the liquid agent container 18 is not required, the liquid agent unit 70 can be obtained at a low cost.

  In the present embodiment, the grooves 102 and 104 are formed along the height direction (longitudinal direction) of the liquid agent container 18, and the joint hose 54 is wound along the height direction of the liquid agent container 18. For this reason, compared with the case where the joint hose 54 is wound along the width direction of the liquid agent container 18, the curvature of the joint hose 54 can be made small, and the kink (folding) which arises in the joint hose 54 is suppressed. Can do.

  Normally, although not shown, the gas / liquid supply pipe extends substantially horizontally toward the outside of the liquid agent container 18, so that the joint hose 54 is connected to the gas / liquid supply pipe. When 54 is wound around the surface of the liquid container 18, kinks are generated at the connection portion of the joint hose 54 with the gas-liquid supply pipe 50.

  For this reason, in this embodiment, as shown in FIG. 1, the gas-liquid supply pipe 50 is extended toward the groove 102 of the liquid agent container 18. Thereby, the kink which arises in the joint hose 54 can be suppressed.

  In this embodiment, as shown in FIG. 3, the joint hose 54 is fitted into the grooves 102 and 104 formed in the liquid container 18 so that the joint hose 54 is wound around the surface of the liquid container 18. Yes. Although this is sufficient, in order to prevent the joint hose 54 from coming off from the liquid agent container 18, as shown in FIG. 5 (B), the front surface 18D of the liquid agent container 18 or A protrusion 110 that protrudes toward the opening of the groove portions 102 and 104 may be provided along the back surface 18E to make it difficult for the joint hose 54 in the groove portions 102 and 104 to come off.

  As described above, the inner sides of the groove portions 102 and 104 serve as standing walls 107 to restrict the movement of the joint hose 54 to the inner side of the groove portions 102 and 104 (in the direction of the arrow A). The portion 108 is provided to restrict the movement of the joint hose 54 to the outside (in the direction of arrow B) of the groove portions 102 and 104. For this reason, the protrusion 110 protrudes toward the opening of the groove portions 102 and 104 so as to restrict the movement of the joint hose 54 in the direction in which the groove portions 102 and 104 come out (arrow C direction).

  In addition to this, in order to prevent the joint hose 54 from being detached from the solution container 18, the surface of the solution container 18 may be covered with a stretch film 112 as shown in FIG. Here, when the joint hose 54 is used, the valve adapter 56 side is removed from the groove portion 104, so that the cut line 112A of the stretch film 112 is in the vicinity of the groove portion 104A on the valve adapter 56 side of the joint hose 54 and in parallel with the groove portion 104A. To form.

  Here, since the surface of the liquid container 18 is covered with the stretch film 112, the joint hose 54 does not necessarily have to be fitted into the grooves 102 and 104 as shown in FIG.

  For example, as shown in FIG. 9B, the depth of the grooves 114 and 116 may be reduced so that the joint hose 54 is wound along the grooves 114 and 116. Even if the joint hose 54 protrudes from the outer shape (indicated by phantom lines in FIG. 9A) connecting the front surface 18D, the back surface 18E, and the side surface 18F of the liquid agent container 18 while being wound around the grooves 114, 116, the joint hose Since the outside of 54 is covered with the stretch film 112, the joint hose 54 does not get in the way.
