Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire cover that also serves as an air jack.

[0002]

2. Description of the Related Art A publicly known Japanese Utility Model Laid-Open No. 4-60785 discloses a tire cover which surrounds the outer circumference of a tire.

[0003]

The above-mentioned known example has no added value because it is merely a decorative tire cover that surrounds the tire.

[0004]

It is an object of the present invention to provide a tire cover that also serves as an air jack, expand the range of use of the tire cover, and add added value.

[0005]

SUMMARY OF THE INVENTION The present invention forms a bag body 11 which is foldable into a cup shape and expands when a gas is injected by a flexible and airtight member. Reference numeral 11 denotes a cup shape having a size for accommodating the tire 4 when folded, and has a size capable of forming a folded-back portion 20 surrounding the tire back side 9 of the tire 4, and the bag body 11 has an exhaust gas of the vehicle body 1. This is a tire cover that also serves as an air jack, to which the base of a connection hose 12 provided with an exhaust connection 14 that connects to a pipe 13 is attached. The present invention provides a tire cover that also serves as an air jack, in which a plurality of small piece members 21 through which a tightening member 22 can be inserted are fixed to the folded-back portion 20 at predetermined intervals.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Is a vehicle body, and 2 is a tire mounting portion provided on the vehicle body 1. The wheel 5 of the tire 4 is applied to the tire mounting portion 2 and is detachably mounted with a bolt. 7 is a tread portion of the tire 4, 8 is a front side surface of the tire 4, and 9 is a back side surface.

Then, the tire cover 10 also serving as an air jack is put on the outside of the tire 4. The tire cover 10 also serving as an air jack has a base portion of the connection hose 12 fixed to a bag body 11 which is inflated by injecting gas, and an exhaust connection portion 14 connected to an exhaust pipe 13 of the vehicle body 1 is provided at a tip of the connection hose 12. An opening / closing cock 15 and a check valve 16 are provided between the exhaust connection portion 14 and the base portion. The bag body 11 is formed in an arbitrary shape, but when it is inflated, it preferably has a so-called rice-bale shape, and is stable when positioned between the ground and the vehicle body 1. Reference numeral 17 is an outer peripheral tubular portion, 18 is one of upper and lower side surfaces, and 19 is the other side surface.

Therefore, the bag body 11 is formed of a flexible and airtight member, and the diameter of the bag body 11 is made larger than the diameter of the tire 4 to form the cup-shaped bag body 11. When the tire 4 is covered, the outer peripheral cylinder portion 17 is left over the tread portion 7 of the tire 4, and the folded-back portion 20 is formed so that it can be folded back to the tire rear side 9 side. Although not shown, a small piece member 21 is attached and fixed to the outer peripheral cylindrical portion 17 of the portion corresponding to the folded-back portion 20 so as to form a clearance for an insertion hole with the outer surface of the bag body 11. Small piece 2
1 is provided in plural at a predetermined interval in the circumferential direction of the bag body 11,
A tightening member 22 formed of a wire, a string or the like is inserted into each small piece member 21. Locking members 23 are attached and locked to the ends of the tightening members 22, respectively.

The bag body 11 is folded inward from a substantially central portion so that one side surface 18 and the other side surface 19 are overlapped with each other to form a cup shape, and in this state, the tire 4 is covered with the folded-back portion 20 on the tire back side surface of the tire 4. Fold it to the 9 side,
Next, the fastening member 22 passed through each small piece member 21 is pulled to fix the bag body 11 to the tire 4.

[0010]

Next, the operation will be described. The present invention has the above-described configuration, and the tire cover 10 also serving as the air jack is a bag body 11 formed of a flexible and airtight member.
Since it is composed of one side surface 18 and the other side surface 19
When it is folded inward so as to polymerize, it can be made into a cup shape.

The bag 11 is attached to the tire mounting portion 2 of the vehicle body 1.
The tire 4 is attached to the outer circumference of the tread portion 7 of the tire 4. When the bag body 11 is put on the tire 4, the doubled outer peripheral cylinder portion 17 portion of the bag body 11 protrudes beyond the tread portion 7 of the tire 4, and the protruding outer peripheral cylinder portion 17 portion is the side surface 9 on the back side of the tire. Since the folded-back portion 20 is formed so that it can be folded back, the folded-back portion 20 is folded toward the tire back side 9 side surface of the tire 4 to cover the tire back side 9 side surface.

A small piece member 21 is formed in the folded portion 20 so as to form a clearance for an insertion hole with the outer surface of the bag body 11.
Are attached and fixed at predetermined intervals, and the tightening member 22 formed of a wire, a string or the like is inserted into each small piece member 21, so that the folded back portion 20 is fixed to the tightening member 22.
The lock member 23 at the end of the tightening member 22.
When the ends of the tightening member 22 are connected by, the mounting on the tire 4 is completed and the tire cover 10 is obtained.

When the lock member 23 is removed and the tightening member 22 is loosened, the bag body 11 can be removed from the tire 4, the bag body 11 is sandwiched between the ground and the vehicle body 1, and the connection hose 12 is inserted. When the exhaust connection portion 14 of the vehicle body 1 is connected to the exhaust pipe 13 of the vehicle body 1 and the opening / closing cock 15 is opened, the bag body 11 is inflated by the exhaust gas from the exhaust pipe 13 and lifts the vehicle body 1 so that it can be used as a so-called air jack. Become. In this case, since the small piece member 21 is simply attached to the outer periphery of the bag body 11, no problem occurs in the expansion of the bag body 11.

[0014]

The present invention forms a bag body 11 which is foldable in a cup shape by a flexible and airtight member and expands when gas is injected, and when the bag body 11 is folded, the tire 4 is formed. Is formed in a cup shape having a size for accommodating the exhaust gas and has a size capable of forming a folded-back portion 20 surrounding the tire rear side surface 9 of the tire 4, and the bag body 11 is connected to an exhaust pipe 13 of the vehicle body 1. Since the tire cover is also used as the air jack to which the base portion of the connection hose 12 provided with the connection portion 14 is attached, the bag body 11 is sandwiched between the ground and the vehicle body 1, and the exhaust connection portion 14 of the connection hose 12 is attached to the vehicle body. When the open / close cock 15 is opened by connecting to the exhaust pipe 13 of No. 1, the bag body 11 is inflated by the exhaust gas from the exhaust pipe 13 to lift the vehicle body 1 and can be used as a so-called air jack.
When 1 is folded inward, it becomes a cup shape, and when this is covered on the outer circumference of the tread portion 7 of the tire 4, it can be used as a tire cover. The present invention provides a tire cover that also serves as an air jack, in which a plurality of small piece members 21 through which the tightening member 22 can be inserted are fixed to the folded-back portion 20 at predetermined intervals. Therefore, the tightening member is used as a tire cover. Not only can it be firmly attached by 22 to prevent it from coming off, but since the small piece member 21 is only attached to the outer periphery of the bag body 11, it does not affect the expansion of the bag body 11 when used as an air jack. Play.
