Description

  The present invention provides an emergency repair of a punctured tire itself without replacing the punctured tire with a spare tire mounted on a vehicle when a tire used for a wheel of a passenger car, a truck, a bus, or the like is punctured due to an unexpected factor. The present invention relates to an emergency repair device that can be used continuously.

  Pneumatic tires used in vehicles, that is, when the tires get over a foreign object having a sharp shape such as broken glass or nails on the road surface, or are damaged artificially by a sharp shape such as a knife. In various unintended situations, such as the case, a pointed shape is pierced into the rubber constituting the tread portion, shoulder portion, sidewall portion, etc. of the tire to form a hole, and the air of the designated air pressure in the tire leaks, There may be a problem that the air pressure in the tire cannot keep the specified air pressure.

  When such a malfunction occurs, the tire is filled with air by sealing the above-mentioned hole with a sealing agent, that is, repair liquid, without replacing the tire itself and the rim on which the tire is mounted. It has been proposed to perform emergency repair to restore the air pressure to the specified air pressure. As an emergency repair device for simply executing such emergency repair, for example, the one described in Patent Document 1 is used. Has been proposed.

  The emergency repair device described in Patent Document 1 includes a sealing agent bottle containing a sealing agent, and pressurized air is injected into the bottle from the bottle to the tire. After injecting the sealing agent, a compressor for supplying pressurized air into the tire and a hose for injection are provided.

  In the event of tire punctures, the driver or operator performs connection processing by connecting the power cable of the emergency treatment device to the vehicle cigar socket to secure power and connecting the hose to the rim valve. After that, the compressor is electrically operated based on a manual switch-on operation to inject the sealing agent into the tire, and then pressurized air is also injected into the tire based on the operation of the compressor. Perform the injection process.

  In this way, after injecting the sealing agent and air into the tire, remove the power cable from the vehicle's cigar socket, execute the removal process to remove the hose from the rim valve, start the vehicle and run it to run the wheels Preliminary running to rotate is executed, and the sealing agent is uniformly diffused in the tire to close the hole causing the puncture, that is, the closing process is executed. After executing the closing process, the connecting process and the injecting process are performed again. After the air pressure in the tire becomes the designated air pressure, the removal process is finally performed, and the series of operations is completed. .

JP 2008-126579 A

  However, in the emergency repair device shown in Patent Document 1, among the processes described above, the closing process is performed by removing the power cable of the emergency treatment device from the cigar socket and removing the hose from the rim valve. The injection process can only be performed later, and the injection process can only be performed after connecting the power cable to the cigar socket and connecting the hose to the valve on the rim. Can not do it. For this reason, the problem that the working time and burden of a driver | operator or a worker are caused arises.

  Furthermore, the processing time of the injection process due to air leakage is unavoidable because the process of injecting compressed air into the tire before the reliable blockage process is performed is particularly unavoidable. However, this increases the work time.

  Moreover, in the emergency repair apparatus as shown in Patent Document 1, the compressor requires a power source, and a motor for operating the compressor, a power cable connected to the cigar socket, a switch for selecting on / off of the compressor, etc. It is necessary to have the electrical system parts of the system, which increases the complexity and weight of the structure, and it is indispensable to repeatedly connect and disconnect the power cable in the series of work in emergency repair. However, there arises a problem that the working time is increased.

  For this reason, it can not be said that the prior art emergency repair device can always realize a more appropriate emergency repair device for performing more reliable and quick emergency repair, without causing a complicated structure and an increase in weight. However, there has been a problem that it is not always possible to satisfy the recent request that it is preferable to suppress the increase in working time and burden as much as possible.

  In view of the above problems, an object of the present invention is to provide a more appropriate emergency repair device for preventing an increase in working time and burden without causing a complicated structure and an increase in weight.

In order to solve the above problem, the emergency repair device according to the present invention is:
Storage means for storing repair fluid;
Injection for injecting the repair liquid stored in the storage means with compressed air into a space defined between a tire and a rim and then injecting the air into the space Means,
Holding means for holding the storage means and the injection means;
Locking means for locking the holding means to the rim;
Support means for supporting the holding means relative to a vehicle body of a vehicle so as to be relatively rotatable;
Power transmission means for causing the injection means to execute the injection processing based on relative rotation of the holding means with respect to the vehicle body.

  The emergency repair device includes a connecting pipe serving as a communication means for communicating the space defined between the tire and the rim, the storage means, and the storage means and the injection means.

  Furthermore, the holding means has a center axis that is the same as the center axis of the tire and the rim, for example, and is configured by a bottomed cylindrical casing that is positioned on the outer side in the vehicle width direction of the vehicle. The injection means is disposed at an arbitrary position of the casing and is held by the casing. Moreover, the said latching means is comprised by the nail | claw part extended radially from the vehicle width direction inner side end of the said casing to the vehicle width direction inner side and radial direction outer side, and latched to the outer periphery of the said rim | limb.

  In addition, the support means is constituted by a combination of a link mechanism having one or more links and a bearing. One end of the link mechanism is fixed to the vehicle body side of the vehicle by appropriate fixing means such as a magnet, a suction cup, a clip, etc., and the other end of the link mechanism passes through the bottom of the casing in the vehicle width direction, It is connected to the input side of the power transmission means and is rotatably supported by a bearing provided around the central axis at the bottom of the casing in the vehicle width direction.

  The power transmission means is constituted by a gear mechanism having an appropriate gear ratio, and when the injection means is a reciprocating compressor, the input side of a crank mechanism that converts the relative rotation included in the compressor into a reciprocating motion And the other end of the support means. When the injection means is a scroll compressor, the input side of the compressor and the other end of the support means are connected.

  According to the emergency repair device of the present invention, the rotational force of the tire and the rim accompanying the driving force of the engine or motor that drives the vehicle is transmitted to the holding means by the locking means, and the supporting means When the holding means is rotated relative to the other end, a rotational force is transmitted from the other end of the support means to the input side of the power transmission means when viewed with respect to the holding means. It becomes.

  For this reason, in order to cause the injection means to execute the injection processing, it is possible to utilize the fact that the holding means is rotated relative to the vehicle body based on the transmission of the rotational force. The compressor does not require a power source, and does not require electrical system components such as a motor for operating the compressor, a power cable connected to a cigar socket, and a switch for selecting on / off of the compressor. It is possible to prevent the structure from becoming complicated and the weight from being increased. In addition, the connection process and the removal process of the power cable are unnecessary, and this can also prevent an increase in working time.

  Furthermore, according to the emergency repair device of the present invention, in performing the injection process of injecting the repair liquid and the pressurized air into the space in this order, by rotating the tire and the rim, Since the injection means is operated, the injection process of injecting the repair liquid into the space is executed, and the injected repair liquid is rotated in the space with the rotation of the tire and the rim. It is possible to uniformly spread and fill the hole causing the puncture with the repair liquid to close the hole, that is, to perform the closing process.

  In other words, since the first half of the injection process, in which the repair liquid is injected, and the closing process can be executed at the same time, the working time of the driver or the operator can be shortened and the burden can be reduced. Furthermore, in the prior art, the latter half of the injection process, in which pressurized air is injected into the space, is executed before the blocking process is reliably executed, and the air leakage causes the According to the emergency repair device of the present invention, it was not possible to prevent an increase in the processing time of the injection process, but the pressurized air was removed after the clogging process was reliably performed. Since the latter half of the process of injecting into the space can be performed, it is possible to prevent air leakage, prevent an increase in the processing time of the injection process, and prevent an increase in work time.

  Furthermore, in the prior art, among the processes described above, the closing process can be performed only after the removal process of removing the power cable of the emergency processing device from the cigar socket and removing the hose from the valve of the rim, Since the injection process can be performed only after the connection process of connecting the power cable to the cigar socket and connecting the hose to the valve of the rim is executed, the connection is continued until the air pressure in the space becomes the specified air pressure. However, according to the emergency repair device of the present invention, once the hose is connected to the valve of the rim, a series of operations required for the emergency repair are performed. This eliminates the need to carry out the removal process until the hose is removed, which also increases the work time and burden on the operator or operator. It is possible to prevent incurring.

  Thus, in the emergency repair device of the present invention, it is possible to reduce the work time and reduce the burden on the driver or the operator without incurring a complicated structure and an increase in weight, It is possible to provide a more appropriate emergency repair device when performing more reliable and quick emergency repair.

  According to the present invention, it is possible to provide a more appropriate emergency repair device for preventing an increase in working time and burden without causing a complicated structure and an increase in weight.

  As shown in FIG. 1, the link mechanism 10 is a link mechanism configured by connecting an arm 10a, a ball joint 10c, an arm 10b, and a ball joint 10d in this order. A ball joint 10d constituting one end of the link mechanism 10 is connected to a magnet 10e.

  The magnet 10e allows the link mechanism 10 to be fixed to an appropriate location on the vehicle body B. When the link mechanism 10 is fixed to the body B by the magnet 10e, the arm 10b The arm 10a extends outward in the width direction and is connected to an arm 10a extending downward from above via a ball joint 10c. The arm 10a is connected to the other end 10ae of the arm 10a constituting the other end of the link mechanism 10. The other end portion 10ae is bent in a direction perpendicular to the arm 10a so as to be directed from the vehicle width direction outer side to the vehicle width direction inner side.

  The casing 6 has a bottomed cylindrical shape having a bottomed portion 6a on the outer side in the vehicle width direction that integrally holds the bottle 2 and the compressor 3 on the outer peripheral surface, and is radially extending from a plurality of locations in the circumferential direction at the inner end in the vehicle width direction. A radial portion 7 extending radially outward is provided, and a claw portion 8 that is engaged with a flange portion on the outer side in the vehicle width direction of the rim R that supports the tire T is provided at the outermost diameter portion of the radial portion 7. I have.

  The casing 6 can be locked to the flange portion of the rim R by the locking means including the radial portion 7 and the claw portion 8, and the bottom axis that the casing 6 includes and the center axis of the tire T and the rim R is configured. The cylindrical central axes are arranged at positions where they coincide.

  An outer race of the bearing 9 is fixed around the central axis of the rim R in the bottomed portion 6a on the outer side in the vehicle width direction of the casing 6, and the other end portion 10ae of the arm 10a is an inner race of the bearing 9. The other end portion 10ae is supported so that the bottomed portion 6a on the outer side in the vehicle width direction of the casing 6 is rotatable with respect to the other end portion 10ae and thus the body B.

  The inner end in the vehicle width direction of the other end portion 10ae is drivingly coupled to an input gear constituting the gear mechanism 11, and an output gear constituting the gear mechanism 11 is drivingly coupled to the input side of the crank mechanism 3a of the compressor 3. The crank mechanism 3a and the gear mechanism 11 are supported on the inner peripheral surface of the casing 6 by appropriate means.

  In the repair kit 1 which is the emergency repair device of the embodiment described above, the bottle 2 constitutes a storage means, the sealing agent S constitutes a repair liquid, the compressor 3 constitutes an injection means, and the hose 4 and the hose 5 are The casing 6 constitutes a holding means, the radial part 7 and the claw part 8 constitute a locking means, the bearing 9 constitutes a bearing, the bearing 9 and the link mechanism 10 constitute a connecting pipe constituting the connecting means. The gear mechanism 11 constitutes a power transmission means.

  In the repair kit 1 of the embodiment as described above, first, in a state where both the inlet valve 13 and the outlet valve 14 are in the closed position, the male screw portion of the connector 15 is screwed into the female screw portion of the valve 16 to be liquid-tight. The magnet 10e is fixed to the above-described appropriate portion of the body B, for example, directly above the tire T and the rim R, and the claw portion 8 is locked to the flange portion of the rim R. In this state, when both the inlet valve 13 and the outlet valve 14 are opened, and the vehicle is started to rotate the tire T and rim R, the rotational force of the tire T and rim R passes through the claw portion 8 and the radial portion 7. When the casing 6 is used as a reference, the other end portion 10ae rotates relative to the casing 6 to generate a rotational force, and the compressor 3 is activated to supply the compressed air to the hose 4. Supply and fill the hose 4 with air.

  When air is thus filled in the hose 4, the air in the hose 4 passes through the riser tube 12 and is formed in a gap formed between the liquid level of the sealing agent S in the bottle 2 and the bottle 2. Compressed air is sent in, and the liquid level of the sealing agent 2 is pushed in the direction approaching the bottom surface by the compressed air filled in the space. The sealing agent 2 has an outlet 2b, an outlet valve 14, a hose 5, and a connector. 15, and injected into a space defined by the tire T and the rim R via the valve 16.

  Generated by the compressor 3 when the liquid level of the sealing agent S in the bottle 2 reaches the bottom surface of the bottle 2 by the compressed air and all the necessary amount of the sealing agent S is sent from the bottle 2 to the hose 5. The compressed air is supplied to the hose 5 through the hose 4, the inlet valve 13, the riser tube 12, the bottle 2, and the outlet 2 b, and the sealing agent S in the hose 5 is reduced by the supplied compressed air. The hose 5, the connector 15, and the valve 16 are passed through and injected into the tire T, and all the necessary amount of the sealing agent S is injected into the tire T.

  In this case, since the tire T and the rim R are rotated by the rotational force accompanying the driving force of the vehicle, the injected sealing agent 2 enters the space defined by the tire T and the rim R from the valve 16. At the same time as the injection, it is uniformly diffused over the entire area of the space and filled into the hole causing the puncture to close the hole.

  After all the necessary amount of the sealing agent S has been injected into the tire T and the hole has been filled with the sealing agent S, the hose 5, the connector 15, and the valve 16 have no remaining sealing agent S, and the compressor 3 The compressed air generated is supplied into the tire T through the hose 4, the inlet valve 13, the riser tube 12, the bottle 2, the outlet 2 b, the outlet valve 14, the hose 5, the connector 15, and the valve 16. Along with this, the air pressure in the tire T is increased to the designated air pressure.

  According to the repair kit 1 of the present embodiment described above, the following operational effects can be obtained. That is, the rotational force of the tire T and the rim R accompanying the driving force of the engine or motor (not shown) that drives the vehicle is transmitted to the casing 6 by the claw portion 8 and the radial portion 7 to constitute the other end of the link mechanism 10. When the casing 6 is relatively rotated with respect to the other end portion 10ae of the arm 10a, when viewed from the casing 6, the rotational force is applied to the input gear of the gear mechanism 11 from the other end portion 10ae of the arm 10a. It can lead to being transmitted.

  Therefore, when the injection process for injecting the compressed air is performed after the sealing agent S is injected into the space defined by the tire T and the rim R in the compressor 3, based on the transmission of the rotational force of the tire T. Since it is possible to utilize the fact that the casing 6 is rotated relative to the body B, the compressor 3 can be configured to not require a power source, and is connected to a motor for operating the compressor 3 and a cigar socket of the vehicle. Electrical system parts such as a power cable and a switch for selecting on / off of the compressor 3 can be eliminated, the structure of the repair kit 1 can be simplified, and the weight can be reduced. Further, by eliminating the need for the power cable, it is possible to eliminate the power cable connection process and the removal process from the work required for the repair, thereby shortening the work time required for the repair.

  Furthermore, according to the repair kit 1 of the present invention, when performing the injection process of injecting the sealing agent S and the pressurized air into the space defined by the tire T and the rim R in this order, Since the compressor 3 is operated by rotating the tire T and the rim R as the vehicle travels, an injection process for injecting the sealing agent S into the space defined by the tire T and the rim R is executed. The sealing agent S injected in the space is uniformly diffused by the centrifugal force and the circumferential force generated by the rotation of the tire T and the rim R, and the sealing agent S is injected into the hole causing the puncture. At the same time, it is possible to fill quickly and to close the hole quickly with the sealing agent S.

  That is, the first half of the injection process for injecting the sealing agent S and the closing process for closing the hole with the sealing agent S can be performed at the same time. Can be reduced. In addition, in the prior art, the latter half of the injection process in which the pressurized air is injected into the space in the tire T before the blocking process is reliably executed is caused by air leakage. Thus, according to the repair kit 1 of the present embodiment, the increase in the processing time of the injection process is performed. After the blocking process is reliably executed, the pressurized air is put into the space in the tire T. Since the latter half of the injection process can be executed, air leakage can be prevented, an increase in the processing time of the injection process can be prevented, and an increase in work time required for repair can be prevented.

  Further, in the prior art, the closing process is not performed after the removal process of disconnecting the power cable of the emergency processing device from the cigar socket and disconnecting the connector 15 of the hose 5 from the valve 16 of the rim R after performing the injection process. The injection process can only be performed after connecting the power cable to the cigar socket and connecting the connector 15 of the hose 5 to the valve 16 of the rim R. It has been necessary to repeat the connection process and the removal process until the air pressure in the space in T becomes the specified air pressure. However, according to the repair kit 1 of the present embodiment, the connector 15 of the hose 5 is temporarily removed from the rim. After connecting to the T valve 16, it is not necessary to remove the hose 5 until a series of operations necessary for emergency repair is completed. It is possible to reduce the suppliers of work time and reduce the burden.

  As described above, in the repair kit 1 of the present embodiment, the work time required for repair can be shortened and the burden on the driver or operator can be reduced without complicating the structure and increasing the weight. Can be realized. For this reason, in the present embodiment, a more appropriate repair kit 1 can be provided in performing more reliable and quick emergency repair.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions are made to the above-described embodiments without departing from the scope of the present invention. be able to.

  For example, when the link mechanism 10 is fixed to the body B, appropriate alternative means such as a suction cup, a clip, and screwing can be used instead of using the magnet 10e. Further, when the casing 6 is locked to the tire T or the rim R, instead of the claw portion 8 and the radial portion 7, for example, a separate means for locking to the ventilation hole of the wheel cap can be substituted.

  The present invention relates to an emergency repair device that is applied when a tire puncture occurs in an automobile, and prevents an increase in work time and burden while avoiding a complicated structure and an increase in weight. Therefore, the present invention is useful when applied to various vehicles such as passenger cars, trucks, and buses.
