Description

[Detailed Description of the Invention] The present invention relates to a tire protection member that fits between bead portions, which are openings of an automobile tire, to close the openings.

Generally, before a tire is mounted on a rim, there are openings between the bead parts, so there is a risk that water and dust may enter the hollow part of the tire through these openings and adhere to the inner surface of the tire. At tire manufacturing factories and dealerships, tires are stacked and stored, so tires located at the bottom are at risk of being crushed by the weight of the tires as their bead parts approach each other, causing the tires to become deformed. This caused quality deterioration.

The present invention was developed in view of the above circumstances, and its purpose is to prevent water, dust, and deformation by fitting between the bead parts, which are the openings of the tire, and closing the openings. An object of the present invention is to provide a protective member for automobile tires that can prevent the above problems.

Hereinafter, the present invention will be explained in detail based on preferred embodiments shown in the drawings.

In the figure, reference numeral 1 denotes a thin plate-like base material formed into a band shape of a predetermined length. ing.

The upper surface of this base material 1 is formed into a rectangular parallelepiped shape as shown in FIG. A plurality of formed bulges 3 are integrally formed at intervals in the length direction of the base material 1, and each of these bulges 3 has a length corresponding to the base material 1 in the length direction. The gradient walls 2 are arranged so that the directions are perpendicular to each other and the gradient walls 2 are located near both sides of the base material 1 in the width direction.

This bulging portion 3 is intended to be press-fitted between the bead portions of an automobile tire, and by forming the sloped wall 2 so that the rising angle α from the base material 1 is a required acute angle. The fitting state between the bulging part 3 and the bead part is not easily disengaged and is securely maintained.

Also, FIG. 1 to FIG. 3 2 are the bulging portions 3 shown in FIG. 1 above.
This figure shows a modification example in which the shape of is modified in various ways.
The drawing opening is formed by curving the top wall part of the bulging part 3 into an arc shape. It is formed by

Even if the shape of the bulging portion 3 is modified in various ways in this way, the acute-angled slope walls 2 can be formed near both sides of the base material 1.

FIG. 2 shows an embodiment different from the above embodiment.
In this embodiment, a bulge 3a is integrally formed on the upper surface of the base material 1, and the rising angle α from the base material 1 is an acute angle on the lengthwise side of the bulge 3a. acute angle slope wall 2a
is formed, and an obtuse slope wall 2b whose rising angle β from the base material 1 is an obtuse angle is formed on the other side, and the bulges 3a adjacent to each other in the vicinity of both widthwise sides of the base material 1 are formed. The slope walls 2a on one side and the slope walls 2a on the other side are arranged so as to be alternately located.

By configuring as described above, in this embodiment as well, acute-angled slope walls 2a can be provided near both sides of the base material 1 in the width direction, similarly to the above embodiment.

FIG. 3 shows an embodiment different from each of the embodiments described above. In this embodiment, a bulge 31) is integrally formed on the upper surface of the base material 1, and this bulge 3b An acute sloped wall 2C is formed on the right side of the upper half of both lengthwise sides, and an obtuse sloped wall 2d parallel to the acute sloped wall 2C is formed on the left side of the upper half, and the lower half An obtuse slope wall 2d is formed on the right side, and on the left side of the lower half,
Acute-angle slope walls 2C are formed parallel to the obtuse-angle slope walls 2d, and the acute-angle slope walls 2C are formed near both sides of the base material 1 in the width direction.
are arranged alternately with the obtuse slope walls 2d.

By configuring as described above, in this embodiment as well, it is possible to provide acute slope walls 2C in the vicinity of both sides in the width direction of the base material 1, as well as in the case of the above-mentioned embodiments. To integrally mold a tire protection member using a male mold for molding.

That is, the mold E shown in FIG. 4 has a mold protrusion H rotatably attached to a band-shaped mold substrate F via an opening/closing member G, and the tire protection member is attached to the resin by contraction. Regardless, it can be easily released from the mold, making it possible to integrally mold even a molded product with a slope like the above-mentioned acute-angle slope wall Z.

FIG. 3A shows a sectional view taken along the line III--III in FIG. 3, and FIG. 3A to FIG.
Figure 3 shows a modification in which the shape of each obtuse slope wall 2d is modified in various ways, and the opening in Figure 3 is one in which a vertical wall 2e is formed in place of the obtuse slope wall 2d (1), and the one in Figure 3 An obtuse slope wall 2f is formed with a larger obtuse angle than the obtuse slope wall 2d, and the obtuse slope wall 2f in FIG. 3 is formed with an even larger obtuse angle than the obtuse slope wall 2f in FIG. It is something.

Next, usage conditions of the tire protection member according to the above embodiment will be explained.

Before being mounted on the rim, the tire P is in a state where the bead portions Q are open.

The bulging part 3 at one end in the length direction of the tire protection member R is press-fitted between the bead parts Q against the elastic force of the tire, and the bulge part 3 is fitted between the bead parts Q toward the other end in the length direction. While gradually bending it into an annular shape, each bulging portion 3 is press-fitted,
Finally, one end and the other end of the base material 1 are overlapped.

In the tire protection member mounted in this way, the bulging part 3 is pressed by the elastic force of the tire, so the hollow part of the tire can be closed watertight, and the acute slope wall 2 is attached to the bead part Q. They are fitted so that they bite into each other, so
The tire protection member is firmly fitted without being easily pulled out from the tire.

In addition, in this invention, the length of the protective member is formed to match the length of the inner circumference of the tire with a large diameter so that it can be installed on several types of tires with different diameters. When mounting on a tire with a small diameter, the excess length on the terminal end side is overlapped with the back side of the starting end side, and the bulging part 3 on the terminal end side is formed into a concave shape of the bulging part 3 on the starting end side. It is also possible to configure it so that it is fitted into the back and locked, and it is also possible to make various changes in the shape and arrangement of the bulging portion 3 without departing from the scope of the present invention. It is.

As described above, the present invention has a plurality of bulges that fit between the bead parts, which are the openings of an automobile tire, on the upper surface of the base material, which is formed into a band shape and has flexibility. are provided at intervals in the length direction of the base material, forming sloped walls with acute angles rising from the base material, and these slope walls are located near both sides of the base material in the width direction. .

Therefore, according to the present invention, since the bead parts that are the openings of an automobile tire can be fitted between each other to close the openings, water and dust will not enter the hollow part of the tire, and Even when tires are stacked, the bead portions are not crushed in the approaching direction, so deformation of the tires can be prevented and quality can be maintained.

In addition, since the tire protection member is formed into a band shape, it is possible to stack multiple layers on top of each other when not in use, making it convenient to handle when storing or transporting. be.

Furthermore, since it can be integrally molded by vacuum forming, it has practical effects such as low manufacturing cost and mass production.
