JP 2007-176181 A

  An object of the present invention is to provide a sealing pump-up device capable of operating a compressed air supply means when an opening member is inserted into a repair liquid bottle in consideration of the above facts.

  According to the first aspect of the present invention, the repair liquid is stored in the repair liquid bottle, and the repair liquid bottle has a sealing member that closes the outlet of the repair liquid. An opening member that opens the outlet, compressed air supply means that supplies compressed air from the opened outlet to the repair liquid bottle, and flows out the repair liquid and compressed air from the outlet, and flows out from the outlet. Fluid supply means for guiding the repaired liquid and compressed air to the pneumatic tire, a pressing portion provided on one of the repair liquid bottle and the opening member, and one of the repair liquid bottle and the opening member A switch that is provided and pressed by the pressing portion to start the supply of compressed air by the compressed air supply means.

  According to said structure, if an opening member is inserted in the outflow port of the repair liquid bottle in which the repair liquid was accommodated, the sealing member which plugs up the outflow port will be broken, and the said outflow port will be open | released. Compressed air is supplied from the opened outlet into the repair liquid bottle by the compressed air supply means, and the repair liquid and compressed air flow out from the outlet. The repair liquid and compressed air that have flowed out are guided to the fluid supply means and supplied to the pneumatic tire.

  Here, either one of the repair liquid bottle and the opening member is provided with a pressing portion, and one of the repair liquid bottle and the opening member is provided with a switch. When this switch is pressed by the pressing portion, supply of compressed air by the compressed air supply means is started. That is, when the opening member is inserted into the repair liquid bottle, the supply of compressed air by the compressed air supply means is started. Therefore, since it is not necessary to operate the compressed air supply means by the operator's operation, labor is reduced. In addition, since the compressed air supply means is operated by an operator's operation in the related art, for example, when the repair liquid bottle is detachable, the compressed air is mounted before the repair liquid bottle is attached to the ceiling pump-up device. Although there is a fear that the supply means is operated, in the present invention, such an erroneous operation can be prevented.

  According to a second aspect of the present invention, the repair liquid bottle includes a neck portion that has a through-hole that is raised from the outer periphery of the outlet and through which the opening member passes, and the opening member is penetrated through the through-hole. Then, after opening the outlet, the switch is pressed by the pressing portion.

  According to said structure, the repair liquid bottle is equipped with the neck part. This neck is raised from the outer periphery of the outlet of the repair liquid bottle. Further, the neck portion has a through hole, and when the opening member is passed through the through hole, the sealing member for closing the outflow port is broken and the outflow port is opened.

  Here, after the outlet is opened by the opening member, the switch is pushed by the pushing portion. That is, after the outlet is opened, the supply of compressed air by the compressed air supply means is started. Therefore, the supply of compressed air is not started before the outlet is opened, and the compressed air can be supplied into the repair liquid bottle.

  According to a third aspect of the present invention, there is provided a locking portion provided in one of the repair liquid bottle and the opening member, and provided in either one of the repair liquid bottle and the opening member. The locked portion to which the locking portion is locked after being opened and the switch is pushed by the pressing portion after the locking portion is locked to the locked portion.

  According to said structure, the latching | locking part is provided in any one of a repair liquid bottle and an opening member, and the to-be-latched part is provided in any one of a repair liquid bottle and an opening member. The locking portion is locked to the locked portion after the outlet of the repair liquid bottle is opened by the opening member. As a result, the opening member is fixed to the repair liquid bottle, and the opening member is prevented from coming off.

  Further, after the locking portion is locked to the locked portion, the switch is pressed by the pressing portion. That is, after the outlet of the repair liquid bottle is opened by the opening member and the opening member is fixed to the repair liquid bottle, the supply of compressed air by the compressed air supply means is started. Therefore, compressed air can be reliably supplied into the repair liquid bottle.

  According to a fourth aspect of the present invention, the opening member includes: a base portion provided with the switch; and an insertion portion protruding from the base portion and penetrating through the through hole and inserted into the outlet. The pressing portion is provided on the periphery of the through hole facing the switch when the insertion portion is penetrated through the through hole.

  According to said structure, the open | release member is provided with the base part in which a switch is provided, and the insertion part protruded from this base part. If this insertion part is penetrated by the through-hole of a neck part and inserted in an outflow port, the sealing member which plugs up an outflow port will be broken, and the said outflow port will be open | released. On the other hand, a pressing portion is provided on the periphery of the through hole in the neck. The pressing portion is provided at a position facing the switch provided on the base portion when the insertion portion is passed through the neck through hole.

  Here, by providing the switch on the base portion, even if the repair liquid leaks into the through hole of the neck, the switch is difficult to get wet with the repair liquid. Accordingly, it is possible to suppress contact failure of the switch. Moreover, since the repair liquid which leaks to a base part can be suppressed by sealing the clearance gap between a through-hole and an open member, wetting of a switch can be suppressed with a simple structure.

  According to a fifth aspect of the present invention, the switch covers a pair of electrodes connected to a motor drive circuit that generates compressed air supplied by the compressed air supply means, and covers the electrodes and is in contact with the electrodes. A cover body that is detachably supported; and a conductive body that is provided on the cover body and that makes contact between the electrodes when the cover body is pressed by the pressing portion. .

  According to the above configuration, when the cover body covering the pair of electrodes connected to the drive circuit of the motor is pressed by the pressing portion, the conductive body provided on the cover body is in contact with the pair of electrodes, and between the electrodes Is conducted and the motor is driven. Compressed air is generated by the driven motor, and compressed air is supplied from the air supply means into the repair liquid bottle.

  Here, by covering the pair of electrodes with the cover body, fouling and corrosion of the electrodes are suppressed, and poor contact between the pair of electrodes and the conductive body is suppressed. In addition, when the pair of electrodes and conductors are arranged separately in the opening member and the repair liquid bottle, not only the wiring of the electrode is complicated, but also the wiring spans the opening member and the repair liquid bottle. Liquid bottles cannot be stored separately. Therefore, restrictions arise in these storage locations. Further, when replacing the repair liquid bottle, the wiring of the electrode and the like must be taken into account, and the structure of the repair liquid bottle becomes complicated. On the other hand, in the present invention, the provision of the pair of electrodes and the conductive member on the opening member facilitates the wiring of the electrodes and the like, thereby simplifying the structure and freeing the storage space for the opening member and the repair liquid bottle. The degree is improved, and the replacement of the repair liquid bottle is facilitated.

  By adopting the above configuration, the present invention can operate the compressed air supply means when the opening member is inserted into the repair liquid bottle.

The guide rib 128 suppresses the tilt of the repair liquid bottle 18 and suppresses breakage and damage of the insertion portion 84 inserted into the neck portion 26 of the repair liquid bottle 18. The radius of curvature of the outer surface of the guide rib 128 may be substantially the same as the inner diameter of the neck portion 26 of the repair liquid bottle 18 so that the repair liquid bottle 18 is press-fitted into the guide rib 128.

  A substantially rectangular notch 130 (see FIG. 3) is formed at the edge of the through-hole 126 between the pair of guide ribs 128. The notch 130 is penetrated (passed) by a locking rib 148 of a jig 82 described later. Further, a rectangular hole 132 that penetrates the bottom plate 11 </ b> A of the casing 11 is provided on the outer side of the notch 130 so as to be positioned on the outer side of the outer diameter of the neck portion 26 of the repair liquid bottle 18. An auxiliary locking rib 146 of a jig 82 to be described later is passed through the rectangular hole 132.

(Jig)
Next, the jig 82 will be described.
As shown in FIGS. 3 and 6, the jig 82 includes a substantially rectangular parallelepiped base portion 86 and a rod-like insertion portion 84 protruding from the upper surface of the base portion 86. The base portion 86 can be housed in the housing recess 112 of the casing 11. A flow path 136 (see FIG. 6) is provided inside the base portion 86, and an inlet 138 communicating with the flow path 136 is provided on the side wall of the base portion 86. A pressure-resistant hose 50 can be connected to the inflow port 138.

  On the other hand, the insertion portion 84 passes through the through hole 126 of the casing 11 and can be inserted into the through hole 118 </ b> A of the neck portion 26. The length of the insertion portion 84 is longer than the dimension from the upper surface of the bottom plate 11 </ b> A of the casing 11 to the aluminum seal 30. Further, the distal end portion of the insertion portion 84 is tapered, and when the base portion 86 to which the pressure-resistant hose 50 is connected is accommodated in the accommodation recess 112, the aluminum seal 30 is broken by the distal end portion of the insertion portion 84. It is configured to be. A hollow portion 140 that communicates with the flow path 136 is provided inside the insertion portion 84.

  A pair of annular grooves 142 (see FIG. 6) are formed on the outer peripheral surface of the insertion portion 84, and O-rings 144 are fitted into the annular grooves 142, respectively. The O-ring 144 is brought into pressure contact over the entire circumference of the inner peripheral surface of the annular rib 118 forming the through hole 118A when the insertion portion 84 is passed through the through hole 118A in the neck portion 26. As a result, the pressurized liquid supply chamber 40 is sealed and sealed (sealed) so that the repair liquid 16 and the compressed air do not leak from the gap between the through hole 118A and the neck portion 26.

As shown in FIG. 5, a switch 182 is provided on the upper surface of the base portion 86. The switch 182 is provided at a position facing the pressing portion 180 provided at the periphery of the through hole 118A when the insertion portion 84 is passed through the through hole 118A of the neck portion 26.
As shown in FIGS. 7A and 7B, the switch 182 is a so-called push-type switch, and includes a case 184 and a pair of electrodes 186A accommodated in the case 184. 186B. The case 184 is a rectangular cylindrical member, and its lower end is attached to a recess 188 formed on the upper surface of the base 86. A protrusion protruding outward is formed at the lower end of the case 184. The case 184 is fixed to the base portion 86 by this protrusion engaging with a notch groove formed on the inner wall of the recess 188.

  A wiring path 190 is formed on the bottom wall of the recess 188. Through the wiring path 190, wiring connected to a pair of electrodes 186A and 186B housed in the case 184 is passed. This wiring is connected to a drive circuit S (see FIG. 5) of the compressor unit 12 described later. A cover body 192 is disposed above the electrodes 186A and 186B. The cover body 192 is housed in the case 184 and is urged upward by the restoring force of the coil spring 195 disposed between the pair of electrodes 186A and 186B. On the other hand, a flange portion that protrudes outward is formed at the lower end portion of the cover body 192, and the cover body 192 is brought into the case 184 when the collar portion is hooked on a protrusion formed on the inner peripheral wall of the case 184. In addition to being held, the electrode 186A and 186B are housed in a freely detachable manner. Although not shown, the gap between the case 184 and the cover body 192 is sealed with a sealing material.

  A conductive body 193 having electrical conductivity is provided on the lower surface of the cover body 192. When the cover body 192 is pressed by the pressing portion 180 provided on the neck portion 26 of the repair liquid bottle 18, the cover body 192 moves downward against the restoring force of the coil spring 195, and the conductive body 193 is moved to the electrode 186A, The electrodes 186A and 186B are brought into conduction in contact with 186B. When the electrodes 186A and 186B are electrically connected, a motor M (see FIG. 5) of the compressor unit 12 described later is driven.

  The conductive body 193 may be made of any conventionally known material as long as it has conductivity. The cover body 192 is buried in the case 184 so that the cover body 192 is not pushed by the operator's hand. Furthermore, the shape and mechanism of the switch 182 are not limited to those described above, and can be changed as appropriate. For example, the electrode 186A extends upward from the electrode 186B and is bent toward the electrode 186B so as not to contact the electrode 186B. Then, the electrode 186A may be further bent to the electrode 186B side by the cover body 192 moved downward, and the electrode 186A may be brought into contact with the electrode 186B so that the electrodes 186A and 186B are electrically connected. Furthermore, according to the shape and mechanism of the switch 182, the shape of the pressing portion 180 can be changed as appropriate to a cylindrical shape, a needle shape, or the like.

  Next, as shown in FIG. 3, a pair of auxiliary locking ribs 146 are provided on the upper surface of the base portion 86 so as to rise vertically from the upper surface of the base portion 86 and face the insertion portion 84 therebetween. . These auxiliary locking ribs 146 can be elastically deformed, and a triangular claw portion 146A is projected from the side surface of each distal end side and the insertion portion 84 side in a side view.

  Between the auxiliary locking rib 146 and the insertion portion 84, a pair of locking ribs 148 is provided that rises vertically from the upper surface of the base portion 86 and faces the insertion portion 84. These locking ribs 148 are lower in height than the auxiliary locking ribs 146. The locking ribs 148 can be elastically deformed, and triangular claw portions (locking portions) 148A project from the side surfaces of the respective leading ends and auxiliary locking ribs 146 in a side view. . Note that the claw portion 146A and the claw portion 148A have flat surfaces whose bottom surfaces are parallel to the base portion 86 in a side view.

  The auxiliary locking rib 146 can be inserted into a rectangular hole 132 formed in the bottom plate 11A. Here, as shown in FIG. 4, after fitting the neck portion 26 of the repair liquid bottle 18 into the guide rib 128 and then receiving the jig 82 in the receiving recess 112 of the casing 11 as shown in FIG. 6, the rectangular hole 132. The auxiliary locking rib 146 inserted into the fixing liquid is hooked into the locked groove 124 provided on the outer peripheral surface of the neck portion 26 of the repair liquid bottle 18. That is, when the claw portion 146A comes into contact with the outer peripheral surface of the neck portion 26 of the repair liquid bottle 18, the auxiliary locking rib 146 is elastically deformed, and the interval between the opposing claw portions 146A is widened. When the claw portion 146A reaches the locked groove 124 of the neck portion 26, the auxiliary locking rib 146 is restored, the claw portion 146A is dropped into the locked groove 124, and the flat surface of the claw portion 146A is covered. It is adapted to be caught on the flat surface of the locking groove 124. This prevents the jig 82 from coming out before a locking rib 148 described later is locked in the locked groove 122.

  On the other hand, the locking rib 148 can penetrate the notch 130. Here, as shown in FIG. 6, when the jig 82 is accommodated in the accommodating recess 112 of the casing 11, the claw portion 148 </ b> A that has passed through the notch portion 130 is formed on the inner peripheral surface of the neck portion 26 of the repair liquid bottle 18. It is locked in the provided groove 122 provided. That is, when the claw portion 148A passes (penetrates) through the notch portion 130, the claw portion 148A comes into contact with the inner peripheral surface of the neck portion 26 of the repair liquid bottle 18, and the locking rib 148 is elastically deformed, so that the opposing claw portion The interval between 148A becomes wider. When the claw portion 148A reaches the locked groove 122 of the neck portion 26, the locking rib 148 is restored, and the flat surface of the claw portion 148A is caught on the flat surface of the locked groove 122, and The claw portion 148A is locked. Thereby, the jig 82 is fixed to the repair liquid bottle 18, and the jig 82 is prevented from coming off.

  When the claw portion 148 </ b> A is locked in the locked groove 122, the aluminum seal 30 is pierced by the insertion portion 84 of the jig 82, and the cover body 192 of the switch 182 is pushed by the pressing portion 180. As a result, the cover body 192 moves downward against the restoring force of the coil spring 195, the conductive body 193 is in contact with the electrodes 186A and 186B, and the electrodes 186A and 186B are electrically connected, and the motor M ( Is driven). Strictly speaking, after the aluminum seal 30 is pierced by the insertion portion 84 (or at the same time), the claw portion 148A is locked to the locked groove 122, and the claw portion 148A is further locked to the locked groove. After being locked to 122 (or simultaneously), the conductor 193 contacts the electrodes 186A, 186B.

  As described above, when the aluminum seal 30 of the repair liquid bottle 18 is pierced by the insertion portion 84, it is stored in the storage portion 17 from the hole 31 (see FIG. 6) opened in the aluminum seal 30 to the pressurized liquid supply chamber 40. Repaired liquid 16 flows out. In this state, the compressor unit 12 is operated by a switch 182 to be described later, and the compressed air generated by the compressor unit 12 flows from the inlet 138 into the channel 136 via the air supply path 60 of the pressure hose 50. The compressed air that has flowed into the flow path 136 passes through the hollow portion 140 and flows (supplied) into the accommodating portion 17. As a result, the pressure inside the container 17 of the repair liquid bottle 18 is increased, and the repair liquid 16 in the container 17 is pushed out from the outlet 116A to the pressurized liquid supply chamber 40. The repair liquid 16 pushed out to the pressurized liquid supply chamber 40 flows out from the discharge port 120 to the joint hose 78.

  In addition, although the taper part is provided in the front-end | tip part of the insertion part 84, and the aluminum seal 30 is penetrated by this taper part, the said front-end | tip part is the neck part 26 of the repair liquid bottle 18 at the front-end | tip part of the insertion part 84, for example. You may provide the blade part which the outer peripheral surface slides when it inserts in, and is exposed outside. Further, a blade portion that is pushed up by the distal end portion of the insertion portion 84 inserted into the neck portion 26 may be provided in the neck portion 26 of the repair liquid bottle 18, and the aluminum seal 30 may be pierced by the blade portion. .

(Compressor unit)
Hereinafter, the compressor unit 12 will be described.
As shown in FIGS. 1 and 5, the compressor unit 12 includes an air compressor P that generates compressed air, a motor M as a drive source of the air compressor P, and a drive circuit S of the motor M. The compressor unit 12 includes a power cable extending to the outside of the casing 11, and a plug 15 that can be inserted into a socket of a cigarette lighter installed in the vehicle is provided at the tip of the power cable. By inserting the plug 15 into the socket of the cigarette lighter, power can be supplied to the drive circuit S from a battery (DC 12 V in the present embodiment) mounted on the vehicle. The above-described switch 182 is connected to the drive circuit S, and when the conductive body 193 is in contact with the pair of electrodes 186A and 186B (on state), electric power (current) is supplied to the motor M to drive the motor M. Is done. On the other hand, in a state where the conductor 193 is not in contact with the pair of electrodes 186A and 186B (off state), electric power (current) is not supplied to the motor M, and the motor M is not driven. The compressor unit 12 is set so as to be able to generate compressed air having a pressure (for example, 300 kPa or more) higher than a specified pressure defined for each type of tire 100 to be repaired (see FIG. 1). FIG. 5 is a conceptual diagram of the wiring of the electrodes 186A and 186B, the drive circuit S, etc., and these configurations are not limited at all.

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

  First, when the tire 100 shown in FIG. 1 is punctured, the user takes out the sealing device 10 from the storage space of the vehicle, opens the lid 114 of the casing 11 and joints the hose together with the valve adapter 80 from the storage space 13. 78 is taken out and the valve adapter 80 is connected to the tire valve 102 of the tire 100 (see FIG. 1).

  Next, as shown in FIG. 4, the neck portion 26 of the repair liquid bottle 18 is fitted into the guide rib 128 provided on the bottom plate 11 </ b> A of the casing 11 and attached to the casing 11, and the adapter 79 of the joint hose 78 is attached to the discharge port 120. Connecting. Thereby, the pressurized liquid supply chamber 40 and the inside of the tire 100 communicate with each other through the joint hose 78.

  Next, the plug 15 (see FIG. 5) is inserted into a socket (not shown) of a cigarette lighter installed in the vehicle, and the vehicle engine is started. Thereby, electric power can be supplied from the vehicle battery (DC 12 V in the present embodiment) to the drive circuit S of the compressor unit 12.

  Next, a seal (not shown) attached to the bottom surface of the housing recess 112 is peeled off to expose the through hole 126. Then, the jig 82 and the pressure hose 50 are taken out from the storage space 13 of the casing 11, one of the pressure hose 50 is connected to the compressor unit 12 side, and the other of the pressure hose 50 is connected to the inlet 138 of the jig 82. . Note that these may be stored in the casing 11 in a state where the pressure hose 50 is connected to the compressor unit 12 and the jig 82 in advance.

  Next, the pressure-resistant hose 50 and the jig 82 are housed in the housing recesses 110 and 112 provided on the back side of the casing 11, respectively, and the insertion portion 84 of the jig 82 is passed through the through hole 118 </ b> A of the repair liquid bottle 18. Then, the distal end portion of the insertion portion 84 is inserted into the outlet 116A to break through the aluminum seal 30. At this time, the gap between the insertion portion 84 and the through hole 118A (the inner peripheral surface of the annular rib 118) is sealed by the O-ring 144 fitted to the outer peripheral surface of the insertion portion 84, and the pressurized liquid supply chamber 40 is sealed. .

  When the jig 82 is stored in the storage recess 112, the claw portion 146 </ b> A of the auxiliary locking rib 146 penetrating the rectangular hole 132 is locked in the locked groove provided on the outer peripheral surface of the neck portion 26 of the repair liquid bottle 18. 124. Further, the claw portion 148 </ b> A of the locking rib 148 that has passed through the notch 130 is locked to the locked groove 122 provided on the inner peripheral surface of the neck portion 26 of the repair liquid bottle 18. The jig 82 is locked (fixed) to the repair liquid bottle 18 by the locking rib 148 and the locked groove 122, and the aluminum seal 30 is pierced by the insertion portion 84 in this state.

  Further, after the locking rib 148 is locked in the locked groove 122 (or simultaneously), the cover body 192 of the switch 182 is pushed by the pressing portion 180. As a result, the cover body 192 moves downward against the restoring force of the coil spring 195, the conductive body 193 is in contact with the electrodes 186A and 186B, and the electrodes 186A and 186B are electrically connected. As a result, a current flows through the drive circuit S, the motor M is driven, and compressed air is generated by the air compressor P.

  The compressed air generated by the air compressor P is supplied into the accommodating portion 17 of the repair liquid bottle 18 through the air supply path 60 in the pressure hose 50, the flow path 136 of the jig 82, and the hollow portion 140 ( (See FIG. 6). When the compressed air is supplied into the storage portion 17, the compressed air floats above the repair liquid 16 and forms a space (air layer G) above the storage portion 17. The repair liquid 16 pressurized by the air layer G is pushed out to the pressurized liquid supply chamber 40 through the hole 31 (opened outlet 116A) opened in the aluminum seal 30. The repair liquid 16 pushed out to the pressurized liquid supply chamber 40 flows out from the discharge port 120 and is injected (supplied) into the tire 100 through the joint hose 78. When all the repair liquid 16 in the storage portion 17 is discharged, the compressed air flows out from the discharge port 120 and is injected (supplied) into the tire 100 through the joint hose 78.

  Next, when the operator confirms that the internal pressure of the tire 100 has become the specified pressure using a pressure gauge (not shown), the operator turns off the power switch (not shown) to stop the compressor unit 12 and the valve adapter. 80 is removed from the tire valve 102. Instead of providing a power switch separately, the jig 82 is removed from the housing recess 112 of the casing 11, and the contact between the pair of electrodes 186 </ b> A and 186 </ b> B and the conductive body 193 is released by the restoring force of the coil spring 195. 12 may be stopped. In this case, since the power switch can be omitted, the number of parts can be reduced.

  Next, the worker travels preliminarily for a certain distance (for example, 10 km) using the tire 100 into which the repair liquid 16 is injected within a certain time after the completion of the inflation of the tire 100. Thereby, the repair liquid 16 is uniformly diffused inside the tire 100, the repair liquid 16 is filled in the puncture hole, and the puncture hole is closed.

  After completing the preliminary travel, the operator remeasures the internal pressure of the tire 100, connects the valve adapter 80 of the joint hose 78 to the tire valve 102 again as necessary, and reactivates the compressor unit 12 to define the tire 100. Pressurize to the internal pressure of. 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.

  Here, in the sealing device 10 of the present embodiment, the switch 182 provided on the jig 82 is pressed by the pressing portion 180 provided on the neck portion 26 of the repair liquid bottle 18, thereby driving the motor M of the compressor unit 12. Then, the compressed air is supplied into the accommodating portion 17 of the repair liquid bottle 18. That is, when the repair liquid bottle 18 is mounted on the casing 11 and the jig 82 is stored in the receiving recess 112 of the casing 11, supply of compressed air by the compressor unit 12 is started. Therefore, since it is not necessary to operate the compressor unit 12 by an operator's operation, labor can be reduced. Further, in the conventional configuration in which the compressor unit 12 is operated by an operator's operation, the compressor unit 12 is mounted before the repair liquid bottle 18 is mounted on the casing 11 or before the jig 82 is stored in the storage recess 112. Although it may be actuated, in this embodiment, such an erroneous operation of the compressor unit 12 can be prevented.

  Further, the pressing portion 180 and the switch 182 are provided so that the switch 182 is pressed by the pressing portion 180 after the claw portion 148A of the locking rib 148 is locked in the locked groove 122 (or simultaneously). ing. That is, the supply of compressed air by the compressor unit 12 is started after the aluminum seal 30 is pierced by the insertion portion 84 of the jig 82 and the outlet 116A of the housing portion 17 is opened (or simultaneously). Accordingly, since the supply of compressed air is not started before the outlet 116A is opened, the compressed air can be reliably supplied into the housing portion 17.

  When the claw portion 148A of the locking rib 148 is locked to the locked groove 122, the gap between the insertion portion 84 and the through hole 118A (the inner peripheral surface of the annular rib 118) is sealed by the O-ring 144. . Thereby, since the pressurized liquid supply chamber 40 is sealed, leakage of compressed air to the outside can be suppressed.

  Further, the jig 82 is locked to the repair liquid bottle 18 by the locking rib 148 and the locked groove 122, so that the insertion portion 84 inserted into the storage portion 17 does not come out due to the pressure of compressed air or the like. Further, unlike the screw type, the fixing between the repair liquid bottle 18 and the jig 82 is not loosened due to mechanical vibration of the air compressor P or the like. Furthermore, the conductive body 193 can be brought into contact with the electrodes 186A and 186B with a predetermined contact pressure, and the power supply to the motor M is stabilized. Accordingly, it is possible to supply appropriate amounts of the repair liquid 16 and compressed air to the tire 100.

  Further, since the switch 182 is provided on the base 86, the switch 182 is not wetted by the repair liquid 16. Even if the repair liquid 16 leaks from the gap of the O-ring 144, the repair liquid 16 flows along the insertion portion 84, that is, the switch 182 is provided in the insertion portion 84 that can be a flow path of the repair liquid 16. Therefore, the switch 182 is difficult to get wet with the repair liquid 16. Furthermore, by covering the pair of electrodes 186A and 186B with the cover body 192, contamination and corrosion of the electrodes 186A and 186B are suppressed. Therefore, poor contact between the electrodes 186A and 186B and the conductor 193 is suppressed.

  Further, the provision of the pair of electrodes 186A and 186B and the conductive body 193 on the jig 82 facilitates the wiring and the like of the electrodes 186A and 186B, thereby simplifying the structure and improving the repair liquid bottle 18 and the jig 82. The degree of freedom of the storage location is improved, and the replacement of the repair liquid bottle 18 is facilitated. If the electrodes 186A and 186B and the conductor 193 are arranged separately in the repair liquid bottle 18 and the jig 82, not only the wiring of the electrodes 186A and 186B is complicated, but also the repair liquid bottle 18 and the jig 82. Therefore, the repair liquid bottle 18 and the jig 82 cannot be stored separately. Therefore, restrictions arise in these storage locations. Further, when the repair liquid bottle 18 is replaced, the wiring of the electrodes 186A and 186B must be taken into consideration, and the structure of the repair liquid bottle 18 becomes complicated and expensive.

[Second Embodiment]
Hereinafter, a second embodiment of the sealing pump-up device of the present invention will be described. In addition, the thing of the same structure as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits suitably and demonstrates.

  As shown in FIGS. 8A and 8B (FIG. 8 is an enlarged cross-sectional view corresponding to the BB cross-sectional view of FIG. 3), the second embodiment is the first embodiment. Instead, a pressing portion 202 is provided on the inner peripheral surface of the neck portion 26.

  The pressing portion 202 provided on the inner peripheral surface of the neck portion 26 is a triangular protrusion in a side view (side sectional view). The lower part of the pressing part 202 is provided with a gentle upward slope toward the upper part so that the end of a locking rib 204 described later is not caught. On the other hand, the upper surface of the pressing portion 202 is a flat surface parallel to the end surface of the neck portion 26, and the mounting hole 204A of the locking rib 204 is locked.

  On the upper surface of the base portion 86 of the jig 82, a locking rib 204 is provided that rises perpendicularly from the upper surface of the base portion 86 and faces the inner peripheral surface of the neck portion 26. The locking rib 204 can be elastically deformed, and a mounting hole 204A into which the cover body 208 of the switch 206 is fitted is formed at the tip (upper end) thereof. The cover body 208 is housed in the case 210 of the switch 206, and is held so as to be able to contact with and separate from a pair of electrodes 186A and 186B disposed in the case 210. Further, a conductive body 193 is provided on the lower surface of the cover body 208, and the motor M of the compressor unit 12 (see FIG. 5) is driven by the conductive body 193 being in contact with the pair of electrodes 186A and 186B.

  Here, as shown in FIG. 8B, when the jig 82 is housed in the housing recess 112 of the casing 11, the locking rib 204 that has passed through the notch 130 of the casing 11 is formed on the inner peripheral surface of the neck portion 26. The mounting hole 204 </ b> A provided at the tip of the locking rib 204 is locked to the pressing portion 202 provided on the inner peripheral surface of the neck 26. . That is, when the locking rib 204 is inserted into the neck portion 26 along the inner peripheral surface of the neck portion 26 and the distal end portion of the locking rib 204 comes into contact with the pressing portion 202, the pressing portion while the locking rib 204 is elastically deformed. Get on top of 202. When the mounting hole 204A reaches the upper surface of the pressing portion 202, the locking rib 204 is restored, the pressing portion 202 is inserted into the mounting hole 204A, and the mounting hole 204A is caught on the upper surface of the pressing portion 202. . This prevents the jig 82 from coming out. When the pressing portion 202 is inserted into the mounting hole 204A, the cover body 208 of the switch 206 is pushed by the pressing portion 202 and moves to the electrodes 186A and 186B side. As a result, the conducting body 193 provided on the lower surface of the cover body 208 comes into contact with the electrodes 186A and 186B to conduct between the electrodes 186A and 186B, and the motor M (see FIG. 5) of the compressor unit 12 is driven.

(Operation of Second Embodiment)
Next, the operation of the second embodiment of the sealing pump-up device of the present invention will be described.

  When the jig 82 is stored in the storage recess 112, the claw portion 146A of the auxiliary locking rib 146 that penetrates the rectangular hole 132 is inserted into the locked groove 124 provided on the outer peripheral surface of the neck portion 26 of the repair liquid bottle 18. Dropped. Further, the attachment hole 204 </ b> A of the locking rib 204 that passes through the notch 130 of the casing 11 and is inserted into the neck portion 26 is locked to the pressing portion 202 provided on the inner peripheral surface of the neck portion 26. Thereafter (or at the same time), the cover body 208 of the switch 206 fitted in the mounting hole 204A is pushed by the pressing portion 202, whereby the cover body 208 is moved to the electrodes 186A and 186B, and the conductive body 193 is moved to the electrode 186A, The electrodes 186A and 186B are brought into conduction in contact with 186B. Then, power (current) is supplied to the drive circuit S to drive the motor M, and compressed air is generated by the air compressor P.

  As described above, in the present embodiment, the supply of compressed air by the compressor unit 12 can be surely started after the attachment hole 204A is locked to the pressing portion 202 (or simultaneously). In other words, unless the pressing portion 202 is inserted into the mounting hole 204A, the mounting hole 204A is not locked to the pressing portion 202, and the cover body 208 of the switch 206 is not pushed by the pressing portion 202. Therefore, the compressor unit 12 does not operate before the aluminum seal 30 is pierced by the insertion portion 84 or before the mounting hole 204A is locked to the pressing portion 202. Accordingly, it is possible to supply appropriate amounts of the repair liquid 16 and compressed air to the tire 100. Moreover, since the press part 202 has a function as a to-be-latched part, the number of parts can be reduced.

  In the first and second embodiments, the switches 182 and 206 are provided on the base portion 86 of the jig 82.

That is, the switch 182 may be provided in one of the repair liquid bottle 18 and the jig 82, and the pressing portion 180 may be provided in either the repair liquid bottle 18 or the jig 82. Thereby, at least when the insertion portion 84 of the jig 82 is inserted into the neck portion 26 of the repair liquid bottle 18, supply of compressed air by the compressor unit 12 can be started.

  In the first and second embodiments, the jig 82 is inserted into the neck portion 26 of the repair liquid bottle 18 through the bottom plate 11A of the casing 11, but the neck portion 26 of the repair liquid bottle 18 is not inserted through the bottom plate 11A. You may insert the jig | tool 82 in this. Further, the locking rib 148 as the locking portion is locked in the locked groove 122 as the locked portion provided in the neck portion 26. However, the number and arrangement of the locking rib 148 and the locked groove 122 are not limited. Is not limited to this. For example, the locking groove 122 may be provided on the outer peripheral surface of the neck portion 26 and the locking rib 148 may be locked to the locking groove 122.

  Furthermore, the pressure hose 50 and the jig 82 are accommodated in the storage space 13 of the casing 11 when not in use, but the pressure hose 50 and the jig 82 are accommodated in the housing recesses 110 and 112 even when not in use. May be accommodated. In this configuration, when the repair liquid bottle 18 is attached to the casing 11, the neck portion 26 of the repair liquid bottle 18 is fitted into the guide rib 128, and the auxiliary locking rib 146 and the locking rib 148 are locked to the neck portion 26.
