  Also, the cartridge container 26 is integrally formed with a flow path forming portion 74 having the same shape as that of the base container 24 at the upper end thereof, and a bypass flow having a semicircular cross section is formed in the flow path forming portion 74. A path 76 is formed. Each of the bypass channels 72 and 76 has a cross-sectional area along the radial direction equal to or slightly larger than the cross-sectional area of the joint hose 40.

  In the puncture repair device 10, the container unit 22 can be in either a base state (see FIG. 1) consisting only of the base container 24 or an increased state where the cartridge container 26 is connected to the base container 24. Yes. Further, when the container unit 22 is in an increased state, one of the two types of cartridge containers 26S and 26L can be selected according to the type of the tire 44 and the selected cartridge container 26 can be connected to the base container 24. . That is, when the container unit 22 is in the base state, the capacity of the sealing agent 36 in the container unit 22 is about 400 cc, and when the container unit 22 is in the increased state, the cartridge container 26S is connected to the base container 24. The capacity of the sealing agent 36 in the unit 22 is about 550 cc. When the cartridge container 26L is connected to the base container 24, the capacity of the sealing agent 36 in the container unit 22 is about 700cc.

  In the puncture repair device 10, when compressed air is supplied into the air chamber portion 30 of the base container 24 by the air compressor 20 when the container unit 22 is in the base state, as shown in FIG. As the air pressure in the portion 30 rises, the plunger member 32 receiving the air pressure gradually moves upward (in the injection direction) against the static pressure of the sealing agent 36. As a result, the internal volume of the air chamber portion 30 gradually expands, the internal volume of the liquid chamber portion 28 is reduced by an amount equal to the expansion amount of the air chamber portion 30, and the sealing agent 36 in the liquid chamber portion 28 is It is pushed into the joint hose 40 through the space in 38. The sealing agent 36 is injected into the tire 44 through the joint hose 40.

  In the puncture repair device 10, as shown in FIG. 1B, the plunger member 32 in the base container 24 minimizes the internal volume of the liquid chamber portion 28 by the pressure of the compressed air, and the internal volume of the air chamber portion 30. When the plunger member 32 reaches the inner peripheral side of the bypass flow path 72, the portion of the outer peripheral surface of the plunger member 32 facing the bypass flow path 72 extends from the inner peripheral surface of the base container 24. Separate. As a result, the air chamber 30 communicates with the liquid chamber 28 through the bypass channel 72, and compressed air generated by the air compressor 20 can be supplied from the air chamber 30 into the liquid chamber 28 through the bypass channel 72. become. At this time, most of the sealing agent 36 filled in the liquid chamber portion 28 is injected into the tire 44 through the joint hose 40.

  Therefore, in the puncture repair device 10, when the plunger member 32 moves to the upper limit position, the compressed air generated by the air compressor 20 passes through the pressure pipe 54, the air chamber portion 30, the bypass passage 72, the liquid chamber portion 28, and the joint hose 40. The tire 44 is filled through. Further, when the plunger member 32 moves to the upper limit position, a part of a small amount of the sealing agent 36 remaining in the liquid chamber 28 is pumped into the tire 44 together with the compressed air.

  In the puncture repair device 10, as shown in FIG. 2A or FIG. 2B, when the container unit 22 is in an increased state, the air compressor 20 compresses the air into the air chamber 30 of the base container 24. When air is supplied, the air pressure in the air chamber portion 30 rises, and the plunger member 32 receiving this air pressure gradually moves upward (in the injection direction) against the static pressure of the sealing agent 36, and the liquid chamber portion The sealing agent 36 in 28 is pushed through the neck 38 and into the lower liquid chamber 58 of the cartridge container 26. Thereby, after the sealing agent 36 is filled in the lower liquid chamber portion 58, the liquid pressure in the lower liquid chamber portion 58 gradually increases. In the cartridge container 26, the plunger member 78 that has received the liquid pressure from the sealing agent 36 in the lower liquid chamber portion 58 gradually rises in the cartridge container 26, and the internal volume of the lower liquid chamber portion 58 gradually expands. At the same time, the internal volume of the upper liquid chamber portion 56 is reduced by an amount equal to the expansion amount of the lower liquid chamber portion 58, and the sealing agent 36 in the upper liquid chamber portion 56 passes through the space in the neck portion 62 and the joint hose 40. Pushed out. The sealing agent 36 is injected into the tire 44 through the joint hose 40.

  Thereafter, when the plunger member 78 in the cartridge container 26 reaches the upper limit position, all of the sealing agent 36 accommodated in the upper liquid chamber portion 56 in the cartridge container 26 is pushed out into the joint hose 40. Since the lower liquid chamber portion 58 communicates with the upper liquid chamber portion 56 through 76, the sealing agent 36 moves from the lower liquid chamber portion 58 to the upper liquid chamber portion 56 as the plunger member 32 rises in the base container 24. The sealing agent 36 continues to be pushed out from the upper liquid chamber portion 56 into the joint hose 40.

  In the puncture repair device 10, when the plunger member 32 in the base container 24 reaches the upper limit position, the air chamber portion 30 communicates with the liquid chamber portion 28 through the bypass flow passage 72, and the compressed air is supplied to the air chamber portion 30 and the bypass flow passage. 72 and the liquid chamber part 28 are supplied into the lower liquid chamber part 58 of the cartridge container 26. At this time, since the sealing agent 36 remains in the lower liquid chamber 58 in the cartridge container 26, the remaining sealing agent 36 is injected into the tire 44 in a state of being mixed with air.

  Here, as one method for injecting the sealing agent 36 more efficiently, an operator who performs puncture repair sends out the sealing agent 36 remaining in the lower liquid chamber 58 into the joint hose 40. Therefore, the puncture repair device 10 may be turned over so that the bypass flow path 76 is located on the lower side in the gravity direction, and the device itself is used in a state where it is inverted upside down from the direction shown in FIGS. It may be designed to be As a result, the sealing agent 36 remaining in the lower liquid chamber portion 58 is pushed out into the joint hose 40 through the bypass flow path 76 and the upper liquid chamber portion 56 by the pressure of the compressed air, and from the cartridge container 26. When all the sealing agent 36 is discharged, the compressed air generated by the air compressor 20 is filled into the tire 44 through the base container 24, the cartridge container 26 and the joint hose 40.

After the injection, the tire 44 is filled with compressed air to pump up the internal pressure of the tire 44 to a predetermined specified pressure, and the adapter 48 is disconnected from the tire valve 46.

  The operator travels preliminarily for a certain distance using the tire 44 injected with the sealing agent 36 within a certain time after the pumping up of the tire 44 is completed. As a result, the sealing agent 36 is uniformly diffused into the tire 44, and the sealing agent 36 is filled in the puncture hole to close the puncture hole. After completion of the preliminary traveling, the operator re-measures the internal pressure of the tire 44 with a pressure gauge or the like, screwes the adapter 48 of the joint hose 40 to the tire valve 46 again if necessary, operates the air compressor 20 and tires. 44 is pressurized to a specified internal pressure. Thereby, the puncture repair of the tire 44 is completed, and the tire 44 can be used to travel at a certain speed or less within a certain distance range.

If the container unit 22 is connected to the base container 24 and the container unit 22 is in an increased state, the amount of the sealing agent 36 in the container unit 22 can be increased as compared with the case where the container unit 22 is in the base state. The amount of sealing agent supplied into the tire 44 during puncture repair can be easily increased. Further, if the container unit 22 is in the base state in which the cartridge container 26 is removed from the base container 24, the amount of the sealing agent 36 in the container unit 22 can be reduced as compared with the case where the container unit 22 is in the increased state. The amount of the sealing agent 36 supplied into the tire 44 at the time of puncture repair can be easily reduced.

  In the puncture repair device 10, the cartridge container 26 can be connected to the base container 24 even when the pressure pipe 54 is connected to the base container 24 or when the pressure pipe 54 is not connected to the base container 24. . Accordingly, the cartridge container 26 is connected to the base container 24 at any time after the base container 24 (container unit 22) is loaded into the apparatus main body or before the container unit 22 is loaded into the apparatus main body.

  On the other hand, as shown in FIG. 6, the cartridge container 100 is formed in a substantially cylindrical shape in which an upper end portion and a lower end portion are closed by a top plate portion 118 and a bottom plate portion 120, respectively. The cylindrical neck 122 is integrally formed so as to protrude downward. On the outer peripheral surface of the neck portion 122, a screw thread corresponding to the screw groove formed in the joint portion 110 of the base container 98 is formed. Further, as shown in FIG. 7, a sealing material 124 made of aluminum foil or the like is fixed to the front end surface of the neck portion 122, and the sealing material 124 is in a state where the opening end on the lower side of the neck portion 122 is in a sealed state. It is sealed so that

  As shown in FIG. 6, when the cap 116 is removed from the joint part 110 of the base container 98 and the neck part 122 of the cartridge container 100 is screwed into the inner peripheral side of the joint part 110, the cartridge container 100 is moved to the upper side of the base container 98. In addition, the sealing member 124 of the cartridge container 100 is pierced by the piercing portion 114 of the base container 98, so that the cartridge container 100 communicates with the base container 98. As a result, the container unit 94 enters an increased state in which the cartridge container 100 is connected to the base container 98.

  As shown in FIG. 5, the injection unit 96 has a unit main body 128 formed in a substantially bottomed cylindrical shape and a plate-like leg portion 129 extending from the lower end portion of the unit main body 128 to the outer peripheral side. Provided. In the unit main body 128, a substantially cylindrical pressurized liquid supply chamber 134 that is connected to the base container 98 and communicates with the inside of the container through the discharge port 132 is provided.

  In the puncture repair device 90, as shown in FIG. 5, when the base container 98 is set upright above the injection unit 96, the sealing agent 36 in the base container 98 is injected by its own weight and the action of air pressure described later. It flows into the pressurized liquid supply chamber 134 of the unit 96. At this time, the orifice part 136 adjusts the inflow amount of the sealing agent 36 flowing into the pressurized liquid supply chamber 134 from the base container 98 and the outflow amount of the compressed air rising from the pressurized liquid supply chamber 134 into the liquid agent container, respectively. It has a function to do.

  As shown in FIG. 4, the puncture repair device 90 is provided with a pressure hose 138 extending from the compressor unit 92, and as shown in FIG. 5, the puncture repairing device 90 extends from the injection unit 96 and includes a plug and a socket. A pressure pipe 142 detachably connected to the pressure resistant hose 138 via the coupler joint 140 is provided. The base end of the pressure hose 138 is connected to an air pump in the compressor unit 92, and supplies compressed air generated by the air pump to the pressure pipe 142 side when the compressor unit 92 operates. Further, the pressure pipe 142 has a distal end side penetrating the peripheral wall portion of the unit main body 128, and an opening on the distal end side projects into the pressurized liquid supply chamber 134.

  Here, the pressure hose 138 and the pressure pipe 142 constitute an air supply path for supplying compressed air into the pressurized liquid supply chamber 134. When the compressor unit 92 (air pump) is operated, the pressure hose 138 passes through the pressure hose 138. The compressed air supplied from the air pump is blown into the pressurized liquid supply chamber 134. The pressure pipe 142 is provided with a check valve 144 between the coupler joint 140 and the unit main body 128. The check valve 144 is compressed air from the air pump into the pressurized liquid supply chamber 134. However, the flow of the compressed air and the sealing agent from the pressurized liquid supply chamber 134 to the compressor unit 92 is prevented. Thereby, when the operation of the air pump is stopped, the sealing agent in the base container 98 is prevented from flowing back into the air pump due to the air pressure from the tire 44, thereby causing a failure of the compressor unit 92.

  The puncture repair device 90 is provided with a joint hose 40 having a base end connected to the unit main body 128 via a nipple 146. As shown in FIG. 5, the joint hose 40 communicates with the pressurized liquid supply chamber 134 via a nipple 146, and the open end of the nipple 146 and the open end of the pressure pipe 142 are connected to the pressurized liquid supply. It arrange | positions so that it may mutually oppose in the chamber 134. FIG. As shown in FIG. 4, an adapter 48 that is detachably connected to the tire valve 46 of the tire 44 is provided at the distal end portion of the joint hose 40. Here, the joint hose 40 is configured as a gas-liquid supply path for supplying the sealing agent 36 and the compressed air into the tire 44.

  In the puncture repair device 90, as shown in FIG. 4, the container unit 94 can be brought into the base state by attaching a cap 116 to the joint portion 110 of the base container 98 and sealing it, and FIG. As shown, by removing the cap 116 from the joint part 110 of the base container 98 and screwing the neck part 122 of the cartridge container 100 into the joint part 110, the container unit 94 can be in an increased state. In the puncture repair device 90, the cartridge container 100 is connected to the base container 98 to increase the container unit 94 after the base container 98 is connected to the unit main body 128 and before the base container 98 is connected to the unit main body 128. Can be in a state.

  Next, an operation procedure for repairing the punctured tire 44 using the puncture repair device 90 according to the present embodiment will be described.

  First, the case where the container unit 94 is in the base state will be described. When puncture occurs in the tire 44, the operator puts the sealing cap screwed on the neck portion 106 of the base container 98 with the neck portion 106 of the container unit 94 (base container 98) facing upward. (Not shown) is removed, the male screw part 130 of the injection unit 96 is screwed into the female screw part 108 of the base container 98, the container unit 94 is connected to the injection unit 96, and then the adapter 48 of the joint hose 40 is connected to the tire valve of the tire 44. 46 and screwed into the base container 98 through the joint hose 40.

  Next, as shown in FIG. 4, the operator installs the puncture repair device 90 so that the base container 98 is positioned above the injection unit 96, then operates the compressor unit 92, and the pressure hose 138 and the pressure piping. Compressed air generated by the compressor unit 92 through 142 is blown into the pressurized liquid supply chamber 134 of the unit main body 128.

  As a result, in the pressurized liquid supply chamber 134, a part of the compressed air flows out into the base container 98 through the orifice portion 136. The compressed air flowing out into the base container 98 floats in the sealing agent 36, and forms an air layer G on the upper side of the sealing agent 36 in the base container 98. In the pressurized liquid supply chamber 134, the compressed air that has not flowed into the base container 98 flows as bubbles into the nipple 146 together with the sealing agent 36, and then flows through the joint hose 40 to the tire 44 side.

  At this time, the air pressure of the air layer G formed in the container unit 94 acts on the sealing agent 36 in the pressurized liquid supply chamber 134. This air pressure acts as a pressure for pushing the sealing agent 36 in the pressurized liquid supply chamber 134 into the joint hose 40. The compressed air injected from the tip of the pressure pipe 142 into the pressurized liquid supply chamber 134 forms a high-speed air flow and entrains the sealing agent, that is, becomes a carrier gas and pressurizes and supplies the sealing agent 36. The liquid is transferred from the liquid chamber 134 into the joint hose 40.

  In the puncture repair device 90, the sealing agent 36 that has flowed into the joint hose 40 from the pressurized liquid supply chamber 134 is pumped to the tire 44 side by the pressure of the compressed air and is injected into the tire 44. Thereafter, substantially the entire amount of the sealing agent 36 is discharged from the inside of the base container 98, and when the prescribed amount of the sealing agent 36 is completely injected into the tire 44 through the joint hose 40, the pressure hose 138 and the pressure pipe 142 are connected to the pressurized liquid supply chamber. The compressed air generated by the compressor unit 92 is communicated with the joint hose 40 via the inner space 134 and the internal space of the base container 98, and supply into the tire 44 is started.

  Thereafter, when the operator confirms that the internal pressure of the tire 44 has become the specified pressure by the pressure gauge 93 provided in the compressor unit 92, the operator stops the compressor unit 92 and removes the adapter 48 from the tire valve 46. .

  Further, in the puncture repair device 90, when the container unit 94 is in an increased state, the base container 98 and the cartridge container 100 are in communication with each other. At the initial stage when air is started to be blown, the compressed air forms an air layer G in the cartridge container 100, and the container expands from the inside of the cartridge container 100 into the base container 98, except that In the same operation as when the unit 94 is in the base state, the sealing agent 36 is injected from the container unit 94 into the tire 44, and then the compressed air is filled into the tire 44 to pump up the tire 44.

  An operator travels preliminarily for a certain distance using the tire 44 into which the sealing agent 36 has been injected within a certain time after the completion of pumping up the tire 44. As a result, the sealing agent 36 is uniformly diffused into the tire 44, and the sealing agent 36 is filled in the puncture hole to close the puncture hole. After completion of the preliminary travel, the operator re-measures the internal pressure of the tire 44, screwes the adapter 48 of the joint hose 40 to the tire valve 46 again if necessary, and restarts the compressor unit 92 to define the tire 44. Pressurize to the internal pressure of. Thereby, the puncture repair of the tire 44 is completed, and the tire 44 can be used to travel at a certain speed or less within a certain distance.

  Even in the puncture repair device 90 according to the present embodiment described above, similarly to the puncture repair device 10 according to the first embodiment, if the cartridge container 100 is connected to the base container 98 and the container unit 94 is in an increased state, Compared with the case where the container unit 94 is in the base state, the capacity of the sealing agent 36 in the container unit 94 can be increased, so that the amount of sealing agent supplied into the tire 44 at the time of puncture repair can be increased easily.

  Further, in the puncture repair device 90, the cartridge container 100 can be connected to the base container 98 regardless of whether the base container 98 is connected to the unit main body 128 or the base container 98 is not connected to the unit main body 128. Thus, even after the base container 98 (container unit 94) is loaded into the apparatus main body or before the container unit 94 is loaded into the apparatus main body, the cartridge container 100 is connected to the base container 98 to increase the container unit 94. it can.

  In the puncture repairing apparatus 10 and 90 according to the present invention described above, one cartridge container 26 and 100 is connected to one base container 24 and 98 in order to increase the container units 22 and 94. Although only the case has been described, the container units 22 and 94 may be increased by connecting a plurality of cartridge containers 26 and 100 to one base container 24 and 98.

  In the puncture repair devices 10 and 90, two types of cartridge containers 26S and 26L or cartridge containers 100S and 100L are used. However, the container units 22 and 94 are increased by using one type or three or more types of cartridge containers. You may make it be in a state. Further, the amount of the sealing agent 36 in the cartridge containers 26 and 100 is not limited to the set amount in the present embodiment, and can be set to any amount according to the type of the tire 44 to be repaired. is there.
