Description

  The present invention relates to a tire puncture repair device capable of selectively performing tire puncture repair and filling only air to be filled with compressed air with a changeover switch.

  As a puncture repair device for repairing a punctured tire as an emergency, for example, as shown in FIG. 9, a tire b and a compressor c are connected to a sealing agent container a using a hose d, and the compressor c The puncture sealant in the sealant container a is pumped into the tire b by feeding the compressed air into the sealant container a, and then the tire b is automatically pumped up by the subsequently flowing compressed air Has been proposed. However, this type of apparatus has a problem in that it is inferior in handling because of many man-hours such as assembly of the apparatus and attachment (piping) of a hose at a puncture repair site.

  Therefore, for example, Patent Document 1 proposes an integrated puncture repair device in which a sealing agent storage container, a compressor, and a hose are connected in advance in a case.

Japanese Patent Laid-Open No. 2001-212883

  However, it is said that the frequency of recent punctures is once every 70,000 km, or once every 6 to 7 years, and the frequency of actually using puncture repair devices is extremely low. Therefore, in recent years, a function for filling only the compressed air is added to the puncture repair device, and for example, it is used to increase the pressure of a non-punctured tire whose air pressure has decreased to a standard internal pressure, or to inflate, for example, a rubber boat or a float It is hoped that.

  Accordingly, the present invention accommodates a sealing agent container, a compressor, and a hose in a pre-connected state in a case, and compresses to an air-filled material while ensuring the convenience of the above-described integrated puncture repair device. An object of the present invention is to provide a tire puncture repair device that can selectively fill only air with a changeover switch and has improved versatility.

In order to achieve the object, the invention of claim 1 of the present application provides a storage case,
A compressor that generates compressed air,
A container body that contains a sealing agent that seals a punctured tire, an air intake port that is attached to the mouth of the container body and feeds compressed air from the compressor to the container body, and the container body by feeding the compressed air A sealing agent container having a cap body provided with a sealing agent and a compressed air outlet port for sequentially taking out a puncture sealing agent and compressed air from
And storing a changeover switch interposed between the compressor and the air intake port,
The changeover switch has an inflow port into which compressed air from the compressor flows, and first and second outflow ports that are selectively switched to the inflow port and are conducted.
And while connecting the said 1st outflow port and the said air intake port part by a connection hose,
The sealant / compressed air outlet port is connected to the other end of a puncture repair hose provided at one end with a connection port that can be connected to the punctured tire, and the punctured tire is connected to the second outflow port. The other end of the hose for exclusive use of compressed air which provided the connection port part which can be connected to other air-filled things at one end is connected.

  According to a second aspect of the present invention, the changeover switch is characterized in that the changeover operation is manual.

According to a third aspect of the present invention, the change-over switch has a tubular shape in which a cone-shaped first and second valve seat portions are provided in a center hole, and is between the first and second valve seat portions. A valve case comprising: the inflow port that opens; and first and second outflow ports that open on both outer sides of the first and second valve seat portions;
A valve shaft that is slidable in one direction and the other in the axial direction in the center hole is brought into contact with the first valve seat by sliding to one side to close the first valve seat. A valve shaft provided with a valve body, and a second valve body that abuts on the second valve seat portion and closes the valve seat portion by sliding movement to the other side;
Spring means for urging the valve shaft to one side to close the first valve seat;
And a control lever,
The operation lever includes a push shaft portion that pushes the valve shaft to the other side by manual pushing and closes the second valve seat portion, and a rotation of 90 ° around the shaft center at the push position. It is characterized by comprising stopper means capable of stopping the push shaft portion at the pushing position.

  Since the present invention is configured as described above, the puncture sealant and compressed air are sequentially applied to the punctured tire by connecting the connection port of the puncture repair hose to the punctured tire and driving the compressor. Can be sent in and puncture repair can be done conveniently. In addition, the compressed air hose connection port is connected to a non-punctured tire with reduced air pressure, or an air-filled item such as a rubber boat or a floating bag, and the compressor is driven by switching the changeover switch and driving the compressor. Only air can be fed into the air filling, and the pressure and expansion of the air filling can be conveniently performed.

  Further, a passage for the sealing agent / compressed air related to the puncture repair and a passage for only the compressed air related to the pressure increase and expansion of the air filling material are branched from the changeover switch and formed independently. Therefore, the changeover switch and the compressed air hose are not fouled by the sealing agent by the puncture repair, so that the failure of the changeover switch due to the sealing agent can be prevented and only the compressed air can be filled cleanly. Further, members that are damaged by puncture repair are limited to the sealant container and the puncture repair hose, and an expensive changeover switch is not included. Therefore, the puncture repair can be repeatedly performed only by exchanging the sealant container and the puncture repair dedicated hose, and cost saving can be achieved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view showing a tire puncture repair apparatus according to the present invention, FIG. 2 is an exploded perspective view with a front case part removed, FIG. 3 is a front view with the front case part removed, and FIG. 8 is a puncture repair apparatus. It is a conceptual diagram which shows a piping state.

  As shown in FIGS. 1 to 3, the tire puncture repair device 1 according to this embodiment includes a storage case 2, a compressor 3 that generates compressed air, a container body 4 that contains a sealing agent, and a cap that is attached to the mouth 4 </ b> A. A sealing agent container 6 having a body 5 and an apparatus constituent member including at least a changeover switch 8 interposed between the compressor 3 and the air intake port 7 of the sealing agent container 6 are accommodated.

  The storage case 2 has a vertical flat rectangular box shape in which the front and rear of the peripheral frame 2a are closed by a front plate 2b and a rear plate 2c, and a leg portion having a height of about 1 mm on both sides in the width direction on the bottom surface. To stabilize the installation. In this example, the storage case 2 is detachably attached to the main case 10 having one side (right side in the drawing) of the bottom portion opened in the width direction and the opening 10A of the main case 10. It consists of a closed bottom case 12. The inside of the main case 10 is divided into a first accommodation space 15A that leads to the opening 10A and a second accommodation space 15B adjacent to the first accommodation space 15A by a partition wall 14 that extends vertically.

  The main case 10 can be divided into a front case portion 10F having the front plate 2b and a rear case portion 10R having a rear plate 2c, and both are provided on the side surface on the first housing space 15A side, for example. It is locked by two to three hook portions 16 (shown in FIG. 2) and fixed by, for example, 4 to 6 screw fittings from the rear plate 2c side. The bottom case 12 is guided so as to be slidable in the width direction by, for example, a guide groove (not shown), and in the closed state, it is easily fixed to the main case 10 by a hook portion 17 (shown in FIG. 4). Is done.

  Next, as the compressor 3, various commercially available small-sized compressors that are driven by using an automobile battery as a power source can be used. Since the compressor 3 is heavy, the stability of the puncture repair device 1 is enhanced by attaching the compressor 3 below the second accommodation space 15B and lowering the center of gravity. Above the compressor 3, a pressure gauge 18 for measuring the pressure of the compressed air generated by the compressor 3 and a power switch 19 of the compressor 3 are mounted side by side so as to be visible or operable from the front side. As shown in FIG. 3, the power switch 19 and the pressure gauge 18 and the compressor 3 are partitioned by a partition plate 20 and opened by a notch window 22 provided on the side surface of the main case 10. A storage space 21 is formed. Such an arrangement is useful for securing a wide display portion J (shown in FIGS. 1 and 2) for explaining handling on the front surface of the storage case 2. In the storage space 21, a power cord (not shown) extending from the power switch 19 and connectable to a car cigarette lighter socket, and a compressed air hose 23 to be described later are detachably stored.

  Next, the sealing agent container 6 includes a container body 4 and a cap body 5 attached to the mouth portion 4A. The cap body 5 is stored in the first storage space 15A in an inverted state with the cap body 5 facing downward. Is done. The sealant container 6 can be inserted into and removed from the opening 10A into the first storage space 15A up and down, and the bottom case 12 is slidably guided in the width direction perpendicular to the insertion / removal direction. It is possible to prevent the case 12 from coming off and the sealing agent container 6 from dropping from the opening 10A. In order to prevent the sealant container 6 from rattling in the first storage space 15A, the inner surface of the main case 10 is made of a sponge material, and a cushion 24 (contacted with the bottom surface of the container body 4 (upper surface in the inverted state)) ( Is attached). For the same purpose, the inner side surface of the main case 10 is formed by an arcuate curved surface along the outer side surface of the container body 4. The cushion 24 can absorb vibrations on the vehicle, and can also have an effect of preventing the rubber component in the sealing agent from aggregating and deteriorating due to the vibrations. A cutout window 25 for visually confirming whether the sealing agent container 6 is stored is formed on the side surface of the main case 10.

  Further, the puncture repair device 1 of the present invention can be normally used as a filling machine for compressed air to be filled with air. At this time, heat generated by the operation of the compressor 3 is transmitted to the sealing agent during storage, and sealing is performed. There is a risk of thermal degradation of the agent. However, in the puncture repair device 1 of this example, the partition body 14 separates the first storage space 15A for storing the sealing agent container 6 and the second storage space 15B for storing the compressor 3. Therefore, the partition wall 14 functions as a heat insulating plate, and can block heat from the compressor 3 to prevent thermal deterioration of the sealing agent.

  As shown in FIG. 5, the container body 4 is preferably a bottle-shaped pressure-resistant container having a pressure resistance of 300 kPa or more, and the opening 4A is opened at the tip of the neck 4B.

  The cap body 5 includes, for example, a cylindrical body 32 and a mounting recess 33 that is integrally formed with the body 32 and that inserts and fixes the neck 4 </ b> B of the container body 4. In this example, the body portion 32 has a stepped column shape having a large diameter on one end side (the upper end side in FIG. 5), and the mounting recess 33 is recessed on the end surface on the large diameter side (the upper end surface in FIG. 5). Has been established. The mounting recess 33 is configured to screw the neck portion 4B of the container body 4 with an internal screw provided on the inner wall surface thereof. Further, a packing material 34 is interposed between the bottom surface of the mounting recess 33 and the neck portion 4B, and the mouth portion 4A is hermetically closed.

  Further, in this example, the mounting recess 33 protrudes from the bottom surface thereof into the mouth portion 4A of the container body 4 and protrudes, for example, into a cylindrical boss portion 35, and is stored on the outer peripheral surface of the boss portion 35. In some cases, an inner lid 30 (indicated by a one-dot chain line) that prevents the puncture sealing agent in the container body 4 from flowing out is elastically fitted. The inner lid 30 is automatically detached from the boss portion 35 by the pressure of the compressed air from the compressor 3.

  Further, the barrel portion 32 has a nipple-shaped air intake port portion 7 for sending the compressed air from the compressor 3 into the container body 4, and a puncture sealing agent and compressed air from the container body 4 by feeding the compressed air. A nipple-like sealing agent / compressed air take-out port 41 is provided so as to sequentially feed out the. The air inlet 7 and the sealing agent / compressed air outlet 41 are connected to the inside of the container body 4 via first and second flow paths 42 and 43 passing through the body 32, respectively. Conducted.

In this example, the first flow path 42 is
A lateral flow path portion 42A provided with an open / close port 45 that extends linearly from the air intake port portion 7 in the lateral direction and can be opened and closed by attaching and detaching the open / close cap 44 at the tip;
The vertical flow path portion 42B intersects with the horizontal flow path portion 42A at the conduction port 46 and extends linearly upward from the conduction port 46.

The lateral flow path portion 42A has an upstream main flow path portion 42A2 reaching the air intake port 7 and a downstream main flow path reaching the opening / closing port 45 on both sides of the venturi portion 42A1 having a reduced diameter (flow path diameter). It is formed as a linear venturi flow path provided with the portion 42A3. The longitudinal channel portion 42B extends upward from the conduction port 46 through the trunk portion 32, and the upper end thereof is opened at the mouth portion 47 at the upper end of the boss portion 35. In addition, although the said conduction port 46 can be formed in the said venturi part 42A1, in this example, the case where it forms in the venturi part 42A1 vicinity position of the said main flow path part 42A3 of the downstream is illustrated. Specifically, the distance from the venturi portion 42A1 at the center of the conduction port 46 is set to 3.0 mm or less. The first flow path 42 sends compressed air from the compressor 3 into the container body 4 when the opening / closing port 45 is closed. In the open state of the opening / closing port 45,
Compressed air from the compressor 3 is discharged from the opening / closing port 45. At this time, a negative pressure can be generated in the longitudinal channel portion 42B by the Venturi effect. Therefore, when the puncture sealing agent in the tire is extracted and collected at a tire repair location such as an automobile maintenance shop, the puncture sealing agent in the tire is sucked from the hose 77 dedicated to puncture repair and returned to the container body 4. It can also be used for collection work.

  The second flow path 43 extends linearly upward from the sealing agent / compressed air outlet 41 and its upper end is opened at a mouth 48 at the upper end of the boss 35. In the present example, the mouth portion 48 is illustrated as being formed as a center mouth at the tip of the cylindrical portion 35A that rises along the center axis of the boss portion 35.

The operating lever 64 includes a push shaft portion 65 that pushes the valve shaft 53 to the other side (the front side in this example) by manual push and closes the second valve seat portion 55, and a push position Q. And the stopper means 40 that can stop the push shaft portion 65 at the push-in position Q by rotating the operation lever 64 around the axis 90 °.

  Specifically, the push shaft portion 65 is formed of a straight shaft-shaped base shaft portion 65A and a disk-shaped knob portion 65B bulging at the rear end. The first large diameter portion 56 in the valve case 51 is formed with a wall plate 56A having a hole portion 56A1 concentric with the center hole 52 on the rear end side. The push shaft portion 65 is held so that the base shaft portion 65A is loosely inserted into the central hole 52 and the hole portion 56A1 of the valve case 51, and is concentric with the valve shaft 53 and rotatable about the axis. The

  Further, the stopper means 40 is formed from the side surface of the base shaft portion 65A as shown in FIGS. 7A and 7B in the AA cross-sectional view and the BB cross-sectional view of FIGS. 6A and 6B.
