Description

  The present invention relates to a tire puncture repair device capable of closing a puncture hole of a tire by injecting a sealing agent into the punctured tire.

  Conventionally, when a tire is punctured, there is known a tire puncture repair device that repairs a punctured tire with a sealing agent to increase the air pressure in the tire to a predetermined pressure without performing a tire and wheel replacement operation. Yes. This tire puncture repair device is incorporated in a vehicle together with a compressor, for example, as a puncture repair set instead of a spare tire.

  As this type of puncture repair device, for example, Patent Document 1 discloses that a sealing agent containing natural rubber latex filled in a pressure-resistant container is injected into a punctured tire by an air pressing action of an air compressor to form a puncture hole. A tire sealing and pumping device is disclosed.

In the tire sealing / pump-up device disclosed in Patent Document 1, a plug valve for closing a gas introduction part connected to an air compressor and an outlet valve for taking out a sealing agent contained in a pressure-resistant container are provided. , Each is provided in a pressure vessel.
Japanese Patent Laid-Open No. 9-18779 (paragraphs 0038 to 0042, FIG. 1)

  However, in the tire sealing / pump-up device disclosed in Patent Document 1, for example, during air transportation of a product (finished product) by an airplane or the like, a sealing agent that is pre-pressurized and filled in a pressure-resistant container is used. There is a risk of leakage due to a pressure difference between the external pressure in the air transportation environment and the internal pressure of the pressure-resistant container. That is, there is a possibility that the sealing agent filled in the pressure vessel leaks from the outlet valve provided in the pressure vessel due to the pressure difference between the external pressure in the air transportation environment of the product and the internal pressure of the pressure vessel.

  Further, when performing tire repair work using the tire sealing / pump-up device disclosed in Patent Document 1, the operator may change the tire for some reason (after stopping the operation of the air compressor). When the tip of the hose connected to the valve is detached, there is a concern that the pressurized sealing agent remaining in the pressure resistant container is discharged from the tip of the hose to the outside.

  The present invention has been made in view of the above points, and when a pressure difference occurs between the inside and the outside of the container in the product transport environment, or when the joint mechanism connected to the tire valve is disconnected for some reason. Even so, an object of the present invention is to provide a tire puncture repair device capable of reliably preventing the sealing agent filled in the container from leaking out or discharging to the outside.

  In order to achieve the above object, the present invention provides a tire puncture repair device for injecting a sealing agent into a punctured tire to close a puncture hole of the tire, and a container for accommodating the sealing agent; An inlet port provided with a pressure fluid provided in the storage container and pressurizing the sealing agent; an outlet port provided in the storage container and led out of the sealing agent pressurized by the pressure fluid; and the storage container A joint mechanism that communicates with the outlet port of the tire and is connected to a valve of the tire, and the joint mechanism is seated on the seat portion when not connected to the valve of the tire and performs a sealing function, A valve element is provided that allows the sealing agent to be fed to the tire side apart from the seating portion when connected to the valve of the tire. To.

  According to the present invention, when puncture occurs in a tire, for example, an operator first connects a joint mechanism to a tire valve. When the tire valve is mounted on the joint mechanism, the valve body provided on the joint mechanism is turned on and separated from the seating portion. Next, the operator energizes the pressure fluid supply source to introduce the pressure fluid from the inlet port, and pressurizes the sealing agent accommodated in the container. The pressurized sealing agent is fed to the joint mechanism through the outlet port. The order may be reversed and the joint mechanism may be connected to the tire valve after the pressure fluid is introduced from the inlet port.

  In this case, in the joint mechanism, the valve body is separated from the seating portion by being attached to the tire valve from the off state where the valve body is seated on the seating portion, and a gap is formed between the valve body and the seating portion. Switched to the formed on state. Therefore, the sealing agent introduced into the joint mechanism is allowed to be fed to the tire side through the gap between the valve body and the seating portion, and is sent to the inside of the tire through the tire valve to close the puncture hole.

  Thus, according to the present invention, when the joint mechanism is not connected to the tire valve, the valve body of the joint mechanism is seated on the seating portion and is in the off state, so that the sealing function is exhibited. When air transported by airplane or the like, the sealing agent that has been pre-pressurized and filled in the container can prevent leakage and leakage due to the pressure difference between the external pressure in the air transport environment and the internal pressure of the container. it can.

  Furthermore, according to the present invention, when performing a puncture repair work on a tire, if the operator disengages the joint mechanism from the tire valve for some reason, the valve body instantaneously changes from the on state to the off state. The valve body is switched to be seated on the seat and the sealing function is exhibited. Therefore, in the present invention, even when the joint mechanism is detached from the tire valve for some reason, the pressurized sealing agent remaining in the container is prevented from being discharged from the joint mechanism to the outside. Can do.

  In addition, the valve body of the joint mechanism is provided with a stem that is pressed in a direction away from the seating portion by the convex portion of the valve of the tire, so that the valve body is in an off state where the valve body is seated on the seating portion. It can be smoothly switched to the ON state spaced from the seating portion.

  Even if there is a pressure difference between the inside and outside of the container in the product transport environment, or when the joint mechanism connected to the tire valve is disconnected for some reason, the sealing agent filled in the container is not It is possible to reliably prevent leakage or discharge.

A seal ring 30 that retains airtightness is attached to the opening of the pressure-resistant container 14 that contacts the inner wall of the cap portion 16.

  Further, the outer peripheral surface of the cap portion 16 is connected to a small air compressor 32 (see FIG. 5) described later, and an inlet port 34 into which compressed air (pressure fluid) fed from the air compressor 32 is introduced. Is provided (see FIGS. 1 and 3). The inlet port 34 is provided so as to communicate with a first passage 36 extending in the radial direction of the cap portion 16, and the end portion of the first passage 36 is separated from the seat portion by being separated from the seat portion. A first shutter valve 38 a that opens the one passage 36 is provided.

  That is, as shown in FIG. 3, the first passage 36 is opened (opened) when the first shutter valve 38a is separated (separated) from the seat by the compressed air supplied from the inlet port 34, and the first passage 36 is opened (opened). The inlet port 34 and the chamber 40 in the pressure vessel 14 are in communication with each other. The first shutter valve 38a is locked at a predetermined position by a stopper (not shown).

  Further, an outlet port 42 for feeding the sealing liquid 12 toward the tire side, which will be described later, is provided on the outer peripheral surface of the cap portion 16 that is separated from the inlet port 34 by approximately 90 degrees along the circumferential direction (FIG. 2). reference). One end portion of the tube 18 is connected to the outlet port 42 via a ring-shaped clip 44a, and the other end portion of the tube 18 is connected to the joint mechanism 22 via a ring-shaped clip 44b.

  Further, the cap portion 16 is connected to a tubular body 48 extending from the top to the bottom of the pressure vessel 14 and having a hollow second passage 46 therein. One end portion of the tube body 48 is provided so as to communicate with the outlet port 42 through a communication path, and the other end portion of the tube body 48 is formed as an open end 50 facing the bottom portion of the pressure resistant container 14. . The open end 50 is formed with a plurality of arc-shaped projections spaced apart by a predetermined angle along the circumferential direction, and a gap is provided between adjacent arc-shaped projections.

  In this case, a second shutter valve 38 b that opens (opens) the second passage 46 by being separated from the seating portion is provided in the vicinity of the opening end 50 of the tubular body 48 facing the bottom of the pressure vessel 14. That is, the sealing agent 12 is pressurized by the compressed air supplied from the inlet port 34, and the second shutter valve 38 b is separated (separated) from the seating portion by the pressing action of the sealing agent 12 introduced from the opening end 50 of the tube body 48. ), The sealing agent 12 is fed to the tire side through the outlet port 42 that is opened and communicated with the second passage 46. The second shutter valve 38b separated from the seating portion is locked at a predetermined position by a plurality of ribs shown in FIGS. 2 and 3, a stopper (not shown), and the like.

  As shown in FIG. 4A, the joint mechanism 22 includes a first joint body 52a formed in a substantially cylindrical shape, and a cylindrical portion 56 fitted in the first joint body 52a via a snap ring 54. And a second joint body 52b. A space 58 is formed in the joint mechanism 22 by the cylindrical portion 56 of the second joint body 52b and the first joint body 52a.

  The second joint body 52b is provided with a cylindrical projection (hose port) 60 to which the tube 18 is connected via a ring-shaped clip 44b. The cylindrical projection 60 is fed from an outlet port 42. An input port 62 into which the sealant 12 to be fed is introduced and a third passage 64 through which the input port 62 and the space 58 are passed are provided. The first joint body 52a is formed with an annular portion 68 connected to a tire valve 66, which will be described later, and the sealing agent 12 supplied from the input port 62 is directed to the annular portion 68 toward the tire side. Output port 70 is provided.

  Further, in the space portion 58 of the joint mechanism 22, the communication between the input port 62 and the output port 70 is blocked by being seated on the sealing pad 72, and by separating from the sealing pad 72, A valve body 20 that makes the input port 62 and the output port 70 communicate with each other, and a return spring 74 that presses the valve body 20 toward the sealing pad 72 in the seating direction are disposed.

  The valve body 20 is a poppet type, and includes a disc portion 20a seated on a sealing pad 72, a spring receiving portion 20b provided on one of the disc portions 20a to which the return spring 74 is engaged, and the circular portion. A cylindrical stem 20c provided on the other side of the plate portion 20a and projecting toward the output port 70 is integrally formed. In this case, one end portion of the stem 20c penetrates the hole portion of the sealing pad 72 in the seated state of the valve body 20, and outputs from the hole portion of the seal ring 76 attached to the annular recess of the first joint body 52a. It is provided in a state protruding by a predetermined length toward the port 70 side.

  The tire repair device 10 according to the embodiment of the present invention is basically configured as described above. Next, a work procedure for repairing a punctured tire using the tire repair device 10 is appropriately illustrated. This will be described with reference to FIG. In FIG. 5, the inlet port 34 and the outlet port 42 are illustrated so as to be spaced apart in the opposite direction by 180 degrees for convenience of explanation.

  When the tire T is punctured, the operator first connects the output port 70 of the joint mechanism 22 to the tire valve 66. When the tire valve 66 is mounted on the output port 70 of the joint mechanism 22, the stem 20 c of the valve body 20 is pressed by the convex portion 78 provided on the tire valve 66, and the valve body 20 is returned to the return spring 74. The spring force is overcome and held in an on state spaced from the sealing pad 72 (see FIG. 4B).

  Therefore, the input port 62 and the output port 70 of the joint mechanism 22 are connected through the third passage 64, the space 58, the gap between the valve body 20 and the sealing pad 72, the hole of the sealing pad 72, and the hole of the seal ring 76. It becomes a communication state. At this time, the air compressor 32 is not yet connected to the tire repair device 10.

  Next, the operator inserts the plug 80 of the air compressor 32 into a cigarette socket (not shown) of the vehicle to electrically connect the air compressor 32, and connects the piping tube 82 to the inlet port 34 of the cap portion 16. After the pipe connection work of the tire repair device 10 is thus completed (see FIG. 5), the rectangular first button 84 of the air compressor 32 is pressed to drive the air compressor 32.

  Under the driving action of the air compressor 32, the first shutter valve 38a is separated (separated) from the seating portion by the compressed air supplied from the inlet port 34 of the cap portion 16, and the first passage 36 is opened. The port 34 and the chamber 40 in the pressure vessel 14 are in communication with each other. Therefore, the sealing agent 12 filled in the pressure vessel 14 is pressurized by the compressed air supplied from the inlet port 34.

  The sealing agent 12 is pressurized by the compressed air supplied from the inlet port 34, and the second shutter valve 38b is separated (separated) from the seating portion by the pressing action of the sealing agent 12 introduced from the opening end 48, and the second The passage 46 is opened, and the sealing agent 12 is fed to the joint mechanism 22 through the outlet port 42 and the passage in the tube 18.

  In this case, in the joint mechanism 22, the stem 20 c of the valve body 20 is mounted by attaching the output port 70 to the tire valve 66 from the off state (see FIG. 4A) where the valve body 20 is seated on the sealing pad 72. Is pressed by the convex portion 78 to switch to an ON state (see FIG. 4B) in which a gap is formed between the valve body 20 and the sealing pad 72. Therefore, the sealing agent 12 supplied from the input port 62 of the joint mechanism 22 is supplied to the third passage 64, the space 58, the gap between the valve body 20 and the sealing pad 72, the hole of the sealing pad 72, and the hole of the seal ring 76. Part, the output port 70 and the tire valve 66 are pumped into the inside of the tire T.

  After the injection of a predetermined amount of the sealing agent 12 previously stored in the pressure vessel 14 into the tire T is completed, the compressed air supplied from the air compressor 32 is continuously pumped into the tire T. The internal pressure of the tire T is increased to a predetermined pressure. At that time, the operator confirms that the internal pressure of the tire T has reached the specified pressure by the pressure gauge 86 provided in the air compressor 32, and then presses the second button 88 to deactivate the air compressor 34. Stop supplying compressed air. After the injection of the sealing liquid 12 is completed, the piping tube 82 of the air compressor 32 is removed from the inlet port 34, and then the distal end portion of the piping tube 82 is directly connected to the tire valve 66 so that the air compressor 32 is connected. The compressed air may be directly supplied into the tire T.

  Subsequently, immediately after the internal pressure of the tire T is increased to the specified pressure, the worker performs preliminary traveling of the vehicle for a certain distance using the tire T into which the sealing agent 12 is injected. By this preliminary traveling, the sealing agent 12 injected into the tire T is uniformly diffused along a tire inner wall surface (not shown) and is filled in the puncture hole to close the puncture hole. As a result, puncture repair is completed. After completion of the preliminary travel, the operator connects the joint mechanism 22 or the piping tube 82 to the tire valve 66 again and activates the air compressor 32 to increase the internal pressure of the tire T as necessary. It may be.

  From the above, in the present embodiment, when the joint mechanism 22 is not connected to the tire valve 66, the valve body 20 of the joint mechanism 22 is seated on the seat portion and is in the off state, and the sealing function is exhibited. Therefore, when the tire repair device 10 (product) according to the present embodiment is air-transported by an airplane or the like, the sealing agent 12 that has been pre-pressurized and filled in the pressure-resistant container 14 has an external pressure in the air-transporting environment and an internal pressure of the pressure-resistant container 14. It is possible to prevent leakage and leakage of liquid due to the pressure difference.

  That is, the second shutter valve 38b is opened by the pressure difference between the external pressure in the air transportation environment of the product and the internal pressure of the pressure resistant container 14, and the sealing agent 12 filled in the pressure resistant container 14 leaks from the outlet port 42 of the pressure resistant container 14. Even in this case, since the valve body 20 of the joint mechanism 22 communicating with the outlet port 42 is seated on the seat portion and the sealing function is exhibited, the sealing agent 12 is reliably prevented from leaking to the outside. be able to.

  Note that when the external pressure due to the surrounding environment is lower than the internal pressure of the pressure-resistant container 14 or when the internal pressure of the pressure-resistant container 14 is higher than the external pressure due to the surrounding environment, the valve body 20 is seated on the seat portion and securely closes. Therefore, the second shutter valve 38b is essentially prevented from opening. On the other hand, the first shutter valve 38a acts in the closing direction regardless of whether the external pressure is reduced or the internal pressure is increased. Therefore, the sealing agent 12 is exposed to the outside through the first shutter valve 38a. There is no leakage.

  In the present embodiment, when the puncture repair work for the tire T is being performed, when the operator stops the operation of the air compressor 32 for some reason and then removes the joint mechanism 22 from the tire valve 66. The valve body 20 is seated on the seat portion by the spring force of the return spring 74, and the sealing function is exhibited. Therefore, in the present embodiment, even when the joint mechanism 22 is detached from the tire valve 66 for some reason, the pressurized sealing agent 12 remaining in the pressure-resistant container 14 remains in the output port 70 of the joint mechanism 22. Can be prevented from being discharged to the outside.

  Thus, in this embodiment, even when a pressure difference occurs inside and outside the pressure vessel 14 in the product transport environment, or even when the joint mechanism 22 connected to the tire valve 66 is disconnected for some reason, The sealing agent 12 filled in the pressure vessel 14 can be reliably prevented from leaking or discharging to the outside by the sealing action of the valve body 20 of the joint mechanism 22.

  Furthermore, in this embodiment, for example, the operator mistakes the piping work procedure, and before connecting the output port 70 of the joint mechanism 22 to the tire valve 66, the piping tube 82 of the air compressor 32 is first connected to the inlet. Even when the air compressor 32 is operated by pressing the first button 84 connected to the port 34, the valve body 20 of the joint mechanism 22 that is seated on the seating portion in the off state exhibits a sealing action. By doing so, it is possible to prevent the sealing agent 12 pressurized in the pressure resistant container 14 from being discharged from the output port 70 of the joint mechanism 22 to the outside.

  In other words, in the puncture repair device according to the related art in which the joint mechanism 22 including the valve body 20 that exhibits the sealing function as in the present embodiment is not provided, for example, an operator erroneously repairs the work procedure of piping. There is a concern that the sealing agent 12 accommodated in the pressure-resistant container 14 leaks out or discharges to the outside by performing the above, but in this embodiment, there is an advantage that such a concern is surely wiped out.

  Furthermore, in the present embodiment, even when the sealing agent 12 remains in the pressure vessel 14 after using the puncture repair device 10, the remaining sealing liquid 12 is caused by the valve body 20 of the joint mechanism 22. Since it is prevented from flowing out to the outside due to the sealing action, for example, the pressure-resistant container 14 is suitably stored in a predetermined part in the vehicle without using a plug member (not shown) and the sealing agent 12 remaining. Can do.

  Furthermore, in this embodiment, by providing the valve body 20 of the joint mechanism 22, it is possible to omit the second shutter valve 38 b disposed on the bottom side of the pressure-resistant container 14 and reduce the manufacturing cost. On the other hand, by providing the valve body 20 of the joint mechanism 22 and the second shutter valve 38b, the following advantages can be obtained.

  First, when both the valve body 20 of the joint mechanism 22 and the second shutter valve 38b are provided, the second shutter is provided after the product is manufactured until the product is actually used by the end user. The valve 38b blocks the flow of the sealing agent 12 accommodated in the pressure resistant container 14 to the joint mechanism 22 side. Therefore, the presence of the second shutter valve 38b prevents the valve body 20 of the joint mechanism 22 from coming into contact with the sealing agent 12, so that leakage of the sealing agent 12 and the like can be prevented more reliably.

  Secondly, until the product arrives at the end user's hand, or until the product arrives at the end user's hand and is actually used for the first time, for example, the end user's intention, negligence, other accidental Even when the stem 20c of the valve body 20 of the joint mechanism 22 is pushed inward for some reason such as an event, the sealing agent 12 in the pressure-resistant vessel 14 is closed by the closing action (sealing action) of the second shutter valve 38b. Leakage is prevented and outside air is prevented from entering the pressure-resistant container 14 and deteriorating the sealing agent 12. In other words, unlike the valve body 20 of the joint mechanism 22, the second shutter valve 38 b is provided at a portion that cannot be operated by the end user (a portion where an object cannot be accidentally touched). It is prevented from operating due to negligence or other incidental events.

  Third, when both the valve body 20 of the joint mechanism 22 and the second shutter valve 38b are provided, when the product is used for the first time after the tire T is punctured, the second shutter valve 38b causes the pressure-resistant vessel 14 to be used. Since the flow of the contained sealing agent 12 to the joint mechanism 22 side is blocked and the sealing agent 12 is not filled up to the valve body 20 of the joint mechanism 22, the joint mechanism 22 is mounted on the punctured tire valve 66. It is possible to prevent the sealing agent 12 from being discharged from the output port 70 of the joint mechanism 22 due to a problem in doing so.

  In other words, if the second shutter valve 38b is not provided, the sealing agent 12 may be filled up to the valve body 20 of the joint mechanism 22, and an operator who performs puncture repair work, for example, When trouble occurs in mounting the joint mechanism 22 to the tire valve 66, the stem 20c of the valve body 20 of the joint mechanism 22 may be pushed in and the sealing agent 12 may be suddenly discharged from the joint mechanism 22. On the other hand, in this embodiment, since there is a time lapse between the opening of the second shutter valve 38b and the arrival of the sealing agent 12 at the joint mechanism 22, an unskilled worker who uses the product for the first time is not allowed. Even when the connection of the joint mechanism 22 to the tire valve 66 is confused, it is possible to appropriately cope with the time margin.

  The puncture repair device 10 according to the present embodiment is not limited to a tire for a vehicle such as an automobile. For example, a bicycle tire, a motorcycle tire, a motorbike bicycle tire, an industrial vehicle tire, a wheelchair Of course, the present invention can be applied to various tires including tires for tires, tires for caravans, tires for agricultural and garden vehicles, tires for unicycles, and the like.
