Hereinafter, embodiments of the present invention will be described in detail.
As shown in FIG. 1, the puncture repair kit 1 of the present embodiment includes a compressor device 2 and a bottle unit 3, and the bottle unit 3 includes a bottle container 4 containing a puncture sealing agent and its mouth. It is comprised from the cap 6 which attaches to the part 5 (shown in FIG. 11).

  Here, in the puncture repair kit 1, a feeding hose 29 is connected in advance to the sealing agent / compressed air take-out nozzle portion 7 provided in the bottle unit 3. As shown in FIG. 14, the hose 29 is wound around the cap 6 and stored in the connected state. As shown in FIGS. 2 and 6, the compressor device 2 is stored in a state where the discharge port 8 a of the compressed air discharge cylinder portion 8 is closed by the dust cap 16. At the puncture repair site, the feeding hose 29 is rewound and the dust cap 16 is removed from the discharge port 8a. Then, by inserting the air intake nozzle portion 27 (shown in FIGS. 7 and 8) of the bottle unit 3 into the discharge port 8a, the bottle unit 3 and the compressor device 2 can be directly connected without interposing hoses. Connected.

  As shown in FIG. 3, the compressor device 2 includes, in a storage case 9, a compressor main body 13 having a cylinder 12 that forms a pump chamber 11 between a motor M and a piston 10 connected to the motor M. At least it is stored.

  As shown in FIGS. 1 and 2, the storage case 9 has a small, flat, substantially rectangular parallelepiped shape in which the upper and lower ends of the peripheral wall portion surrounding the four sides with the side plate portion 14a are closed by the upper plate portion 14U and the lower plate portion 14L, respectively. It is formed as a box. The storage case 9 is formed to be disassembled into upper and lower case portions 9U and 9L.

  As the motor M, various commercially available DC motors that operate with a 12V DC power source of an automobile can be used. A power cord provided with a power plug 15 that can be connected to a cigarette lighter socket of an automobile is connected to the motor M via a power switch SW that is attached to the upper plate portion 14U of the storage case 9. The power plug 15 is removably accommodated in a recess (not shown) provided in the lower plate portion 14L.

  Next, as shown in FIGS. 4 and 5, the compressor body 13 includes a piston 10 connected to the motor M via a crank mechanism 17, and accommodates the piston 10 so as to be capable of reciprocating. And a cylinder 12 forming a pump chamber 11 for compressing air therebetween. The piston 10 has an intake hole 19A extending through the piston 10 in the axial direction, and the intake hole 19A is closed from the pump chamber side with a spring property, such as an elastic material such as rubber, synthetic resin, or metal. An intake valve 19 using a valve 19B such as a body is formed.

  In the present example, the cylinder 12 is a surge tank that stores compressed air from the pump chamber 11 at the rear end side of the cylindrical cylinder body 20 forming the pump chamber 11 and suppresses pressure pulsation by the piston 10. A cylinder sub-portion 21 for forming the chamber 21A is integrally provided. In this example, the surge tank chamber 21A is electrically connected to the pump chamber 11 through a small hole 20A1 formed in the partition wall 20A that closes the rear end of the cylinder body 20.

  A compressed air discharge cylinder portion 8 that discharges compressed air protrudes from the peripheral wall of the cylinder sub-portion 21. In this example, a first connecting portion 24A for attaching the pressure gauge 22 and a second connecting portion 24B for attaching the relief valve 23 are provided on the peripheral wall of the cylinder sub-portion 21 in different directions. The

  As shown in FIG. 7, the compressed air discharge cylinder 8 protrudes outwardly through one side plate 14 a 1 of the storage case 9, and opens a discharge port 8 a that discharges compressed air at the tip. ing. The central hole 8H of the compressed air discharge cylinder 8 forms a discharge passage 26 extending from the surge tank chamber 21A to the discharge port 8a, and the bottle unit is formed on the open end side of the center hole 8H. 3 is formed with a nozzle receiving portion 28 that fits into the air intake nozzle portion 27 provided in the third step. In the present example, the nozzle receiving portion 28 has front and rear tapered surface portions 28B and 28C formed in a tapered cone shape toward the cylinder sub-portion 21 before and after the parallel hole portion 28A having a constant inner diameter.

  Next, the bottle unit 3 is composed of a bottle container 4 containing a puncture sealing agent and a cap 6 attached to the mouth portion 5 thereof, and the cap unit 6 is placed in the inverted state with the cap 6 directed downward. Connected directly.

As shown in FIG. 11, the bottle container 4 protrudes from the lower end of the bottle body 30 with a small-diameter cylindrical mouth portion 5 through which a puncture sealing agent can be taken in and out. As shown in FIG. 12, the bottle body portion 30 is formed in a substantially rectangular shape with a cross section perpendicular to the height direction surrounded by a pair of long side portions 30A and a pair of short side portions 30B. In this example, the case where the long side portion 30A and the short side portion 30B are formed in a convex arc shape toward the outside of the bottle is shown. At this time, when the length of the long side portion 30A is W, the radius of curvature of the long side portion 30A is RW, the length of the short side portion 30B is D, and the radius of curvature of the short side portion 30B is RD, the following formula ( It is preferable to set so as to satisfy 1) to (3).
1.3 ≦ W / D ≦ 1.7 (1)
0.5 ≦ RW / W ≦ 3.0 (2)
0.5 ≦ RD / D ≦ 20.0 −−− (3)

  Here, when considering the storability of the puncture repair kit 1 in the vehicle, for example, in the trunk, the compressor device 2 has a substantially rectangular parallelepiped shape. Therefore, the bottle body 30 of the bottle container 4 is also formed in a substantially rectangular parallelepiped shape. Is preferred. However, at the time of puncture repair, a high internal pressure, for example, close to 350 kPa acts on the bottle container 4. At this time, when the bottle body 30 has a circular cross section, the bottle body 30 expands evenly in the radial direction due to internal pressure, so that deformation at the time of filling with compressed air is not recognized so much and anxiety to the user. The feeling is low. However, when the bottle body portion 30 has a rectangular cross section, the swelling due to the internal pressure is not uniform, and the deformation amount is felt to be larger than actual, for example, the bottle body 30 expands so as to approach the circular cross section. For this reason, there is a possibility of giving the user anxiety such as a rupture even though the pressure resistance is within the range.

  Therefore, in this example, the long side portion 30A and the short side portion 30B are each formed in a convex arc shape, and are formed in a shape close to the deformed shape at the time of expansion. Therefore, while improving the storage property, the deformation at the time of filling with compressed air is not recognized so much, and the user's anxiety can be kept low.

  As a result of the inventor's experiment, in order to suppress the feeling of anxiety, it is important to suppress the amount of expansion on the long side, and for that purpose, the length W on the long side is increased and the radius of curvature RW is increased. It is preferable to set a small value. If the ratio W / D is less than 1.3 or the ratio RW / W is more than 3.0, the length W is relatively small or the radius of curvature RW is large and the expansion amount on the long side is increased. Increase. On the contrary, when the ratio W / D exceeds 1.7 or the ratio RW / W is less than 0.5, the storage property is disadvantageous. If the ratio RD / D exceeds 20.0, the amount of expansion on the short side increases, and the deformation at the time of filling with compressed air increases. Conversely, if the ratio RD / D is less than 0.5, This causes a disadvantage in storage.

  The corner portion where the long side portion 30A and the short side portion 30B intersect is preferably formed by an arc 30C having a radius of curvature of 15 mm ± 5 mm in order to ease stress concentration and improve pressure resistance.

  Next, as shown in FIG. 11, the cap 6 includes a disc-shaped bottom plate portion 31 forming a bottom surface 6S, a bottle mounting portion 32 for attaching the mouth portion 5 of the bottle container 4, and a constricted shape disposed therebetween. The body portion 33 is integrally provided. The body 33 has an air intake nozzle portion 27 having an intake port 27a through which compressed air from the compressed air discharge tube portion 8 is fed into the bottle container 4, and the bottle container 4 is fed by the compressed air. A sealing agent / compressed air take-out nozzle portion 7 having a take-out port 7a for sequentially taking out the puncture sealant and the compressed air is provided.

  In the cap 6, an air flow path 35 extending from the intake port 27 a into the mouth portion 5 of the bottle container 4, and a sealing agent / compressed air extending from the take-out port 7 a into the mouth portion 5 of the bottle container 4. An extraction flow path 36 is formed.

  The bottle attachment portion 32 has an attachment recess 32A for fixing the mouth portion 5 and a boss portion 32B protruding from the bottom surface of the attachment recess 32A. The mounting recess 32A can be screwed into the mouth portion 5 by an internal screw provided on the inner wall surface thereof. Further, on the upper surface of the boss portion 32B, an air channel upper opening 37 in which the upper end of the air channel 35 is opened, and a sealing agent / compressed air extraction channel in which the upper end of the sealing agent / compressed air take-out channel 36 is opened. An opening 38 is provided.

  The air flow path 35 includes a vertical air flow path portion 35a extending downward from the air flow path upper opening 37, and intersects the vertical air flow path portion 35a at a right angle at an intersection P and from the intersection P to the intake port. And a horizontal air flow path portion 35b extending to 27a. In addition, a sealing agent storage portion 39 for storing a backflow puncture sealing agent when the puncture sealing agent flows backward from the air flow path upper opening 37 is provided at a lower end portion of the vertical air flow passage portion 35a that extends downward from the intersection P. It is formed. In addition, the sealing agent accommodating part 39 is formed in a larger diameter than the said vertical air flow path part 35a.

  Here, in the puncture repair, first, using the puncture repair kit 1, the puncture sealing agent and the compressed air are sequentially injected into the punctured tire T and pumped up. Thereafter, the user once loads the puncture repair kit 1 removed from the tire T with the compressor device 2 and the bottle unit 3 connected, and travels about 10 minutes to seal the puncture hole. Thereafter, the puncture repair work is completed by reconnecting the puncture repair kit 1 to the tire T again and checking and refilling the air pressure. In these operations, the bottle unit 3 after being filled with the sealant is inclined in various directions and is subjected to vibration. For this reason, the puncture sealing agent remaining in the bottle unit 3 flows backward from the air flow path upper opening 37 to the compressor device 2 side, and the compressor device 2 may be damaged. Therefore, in order to prevent the backflowed puncture sealing agent from flowing into the compressor device 2, the sealing agent accommodating portion 39 is formed. Therefore, the capacity of the sealing agent container 39 may be about the capacity of the sealing agent remaining in the bottle unit 3, and is set in a range of 5 to 15 cc in this example. If the capacity is less than 5 cc, the back-flowing sealing agent may not be accommodated, and if it exceeds 15 cc, the cap 6 is useless, leading to an unnecessary increase in the size of the cap 6, that is, a decrease in storage performance.

  Further, in order to suppress the back flow from the air flow path upper opening 37, a throttle part 35a1 for reducing the inner diameter is provided on the upper end side of the vertical air flow path part 35a, and the inner diameter Da1 of the air flow path upper opening 37 is set to 1.0 to. It is preferable to reduce to the range of 2.0 mm. In addition, by making the inner diameter Da of the vertical air flow path portion 35a larger than the inner diameter Db of the horizontal air flow path portion 35b at the position of the intersection point P, The effect of suppressing the outflow into the air channel portion 35b can be enhanced. In this example, the inner diameter Db of the horizontal air flow path portion 35b is about 3.0 to 5.0 mm. In order to suppress the back flow from the air flow path opening 37, it is also preferable to open the air flow path opening 37 above the sealing agent / compressed air take-off flow path opening 38, and in particular, the air flow path opening 37. It is preferable that the height h from the upper opening 38 of the sealing agent / compressed air take-out flow path is 5.0 to 7.0 mm.

  The sealing agent accommodating portion 39 opens at the bottom surface 6S of the cap 6, and the opening is closed by an accommodating portion lid 40 that is flush with the bottom surface 6S.

  Next, the bottle unit 3 can be directly connected to the compressor device 2 and integrally coupled by fitting the air intake nozzle portion 27 to the nozzle receiving portion 28.

  As shown in FIGS. 7 and 8, the air intake nozzle portion 27 includes a tapered cone-shaped tapered surface portion 41B on the distal end side of the nozzle body 41A having a constant outer diameter. The tapered surface portion 41B has substantially the same inclination as the tapered surface portion 28C behind the nozzle receiving portion 28. Therefore, when the air intake nozzle portion 27 is inserted into the nozzle receiving portion 28, the rear tapered surface portion 28C forms a receiving surface 42 that contacts the tapered surface portion 41B and receives the tapered surface portion 41B. Thereby, the air intake nozzle part 27 and the nozzle receiving part 28 can be directly connected at a concentric and accurate position. The tapered surface portion 28B in front of the nozzle receiving portion 28 functions as a guide when the air intake nozzle portion 27 is inserted.

  The air intake nozzle portion 27 is provided with an O-ring 43 that seals between the inner surface of the nozzle receiving portion 28 (in this example, the inner surface of the parallel hole portion 28A) on the outer periphery of the nozzle body 41A. In this example, a case where two O-rings 43 for securing the seal are mounted is illustrated. By disposing the O-ring 43, which is a consumable item, on the bottle unit 3 side, the compressor device 2 can be used repeatedly without maintenance.

  Next, the cap 6 has locking claws 45 protruding above and below the air intake nozzle portion 27, and the compressor device 2 has the locking claws 45 at a position facing the locking claws 45. By engaging with 45, a claw engaging hole 46 is formed for fixing the compressor device 2 and the bottle unit 3 in the directly connected state.

  The locking claw 45 has a right-triangular hook portion 45B projecting outward at the tip of a main portion 45A extending in parallel with the air intake nozzle portion 27. And the said nail | claw engaging hole 46 is formed in the rectangular hole shape in this example engaged with the said hook part 45B.

  The cap 6 including the locking claws 45 is formed as an integrally molded body made of, for example, plastic such as nylon, polypropylene, or polyethylene, or reinforced plastic in which short fibers such as glass fiber are blended. In this example, the claw engagement hole 46 is formed by a frame frame 47 having a rectangular frame shape, for example, which is fixed to the outer periphery of the compressed air discharge cylinder portion 8 forming the nozzle receiving portion 28 as shown in FIGS. The The frame frame 47, the compressed air discharge cylinder portion 8, and the cylinder 12 are formed as an integrally formed body made of a lightweight alloy such as a zinc alloy or an aluminum alloy, thereby ensuring a necessary strength.

  In this example, as shown in FIGS. 2 and 13, the compressor device 2 is provided with a rod-shaped jig 48 such as a screwdriver in the storage case 9. A guide groove 49 is provided for guiding the engagement portion J to release the engagement. The guide groove 49 is an inclined groove having a groove bottom 49S inclined toward the engaging portion J as a guide surface, and the rod-shaped jig 48 is engaged between the groove bottom 49S and the groove wall surfaces on both sides thereof. You can guide to joint J. Further, since the locking claw 45 has the hook portion 45B outward, the engagement can be easily released by pushing the hook portion 45B inward by the rod-shaped jig 48. The side plate portion 14a1 of the compressor device 2 is formed with a substantially semicircular recess 53 that matches the outer surface shape of the bottle unit 3 and stabilizes the seating of the bottle unit 3.

  Thus, in the puncture repair kit 1, the compressor device 2 and the bottle unit 3 are directly connected without interposing hoses, and in this example, in this connected state, They are fixed to each other by the claw engaging holes 46. Therefore, the bottle unit 3 can be integrated with the compressor device 2 to lower the position of the center of gravity, so that the installation stability can be improved and the bottle can be prevented from overturning. At this time, in the direct connection state, it is important that the bottom surface 6S of the cap 6 and the bottom surface 2S of the compressor device 2 are flush with each other, thereby increasing the ground contact area and increasing the frictional force with the road surface. Therefore, not only the installation stability but also the vibration stability during the compressor vibration can be improved.

  Next, as shown in FIGS. 6, 9, and 10, the compressor device 2 is provided with a dust-proof cap 16 that prevents foreign matter from entering the nozzle receiving portion 28 during storage.

  The dust cap 16 is attached to the discharge port 8a of the compressed air discharge tube portion 8 so as to be detachable and can be plugged to the discharge port 8a, and is externally attached to the compressed air discharge tube portion 8. The ring-shaped fixing part 55 to be attached and the bendable connecting part 56 for connecting the cap part 54 and the ring-shaped fixing part 55 are formed.

  In this example, the case where the cap part 54 is composed of a plug 57 that can be fitted into the discharge port 8a is exemplified. The cap portion 54 has a diameter larger than that of the discharge port 8a, and a stopper portion 58 that restricts the insertion depth of the plug 57 into the discharge port 8a, and the discharge port 8a can be easily detached from the discharge port 8a. And a tongue-shaped picking portion 59. The ring-shaped fixing part 55 is externally inserted into the compressed air discharge cylinder part 8 between the cylinder sub-part 21 and the frame frame 47. The ring-shaped fixing portion 55 has a C-shaped cross section with a slit 55a provided on the side thereof, and the compressed air discharge tube portion 8 can be detached from the slit 55a. The connecting portion 56 has a bendable belt shape. In this example, the dust cap 16 is integrally formed of a synthetic resin in which the cap portion 54, the ring-shaped fixing portion 55, and the connecting portion 56 are integrated. Formed as a body.

  A circumferential groove-like holding groove 55b is formed on the outer periphery of the ring-shaped fixing portion 55 to hold the inner peripheral edge of the through hole 9H of the storage case 9 through which the compressed air discharge cylinder portion 8 passes. The holding groove 55 b is formed on the inner side (cylinder sub-part 21 side) than the connecting part 56.

  As shown in FIG. 15, the cap portion 54 may be a cap body 60 having a fitting hole 60 a that fits to the outer periphery of the compressed air discharge tube portion 8 instead of the stopper 57.

  Thus, by providing the dustproof cap 16, it is possible to reliably prevent foreign matters such as dust and dirt from entering the nozzle receiving portion 28 during storage. As a result, troubles such as poor fitting between the air intake nozzle portion 27 and the nozzle receiving portion 28 due to the foreign matter and clogging of the air valve Tv due to the foreign matter entering the sealing agent during puncture repair can be prevented. The reliability of the puncture repair kit 1 can be improved.

  In the puncture repair kit 1, the bottle unit 3 is a consumable item and is replaced every time the puncture is repaired. However, the compressor device 2 is used repeatedly. Therefore, even after the puncture repair is completed and the used bottle unit 3 is removed from the compressor device 2, it is necessary for the compressor device 2 to prevent foreign matter from entering the nozzle receiving portion 28. In this example, Since the dust cap 16 is held by the compressor device 2, the compressor device 2 can be repeatedly stored cleanly without being lost.

  The feeding hose 29 is connected to the sealing agent / compressed air take-out nozzle section 7, and this feeding hose 29 is arranged around the body section 33 as shown in FIG. 14 when not in use. Wrapped and stored.

  Further, in order to prevent the puncture sealing agent in the bottle container 4 from flowing out when the bottle unit 3 is not used, as shown by the one-dot chain line in FIG. Inner plugs 52 for closing the sealing agent / compressed air extraction flow path upper openings 38 are fitted. The inner plug 52 can be detached from the boss portion 32 </ b> B by the pressure increase due to the compressed air from the compressor device 2.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
