Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention can be used in various vehicles and can be used in various road conditions (normal roads, snowy roads, icy roads). All tires have a part of the tire contact surface that can be changed to accommodate This invention relates to seasonal tires.

0002

[Conventional technology]

In general, standard tires installed on vehicles such as cars and trucks do not match the road surface condition. Safely drive on roads with reduced friction, such as snowy roads or frozen roads. In such cases, you may be unable to use the touch screen whenever necessary. Install ear chains or use spiked tires (regular tires) during the winter. If you attach a spike made of metal or other material to the head with the head protruding, A similar method was adopted. Among these, the method of installing tire chains is They tend to be avoided because they are troublesome to put on and take off, and on the other hand, those with spiked tires In some cases, spikes should not be used as the vehicle will be driving on general paved roads, excluding snowy and icy roads. It scrapes the road surface with its protruding head.

0003 As a result, in recent years, road surface damage caused by spiked tires installed on vehicles has become noticeable. Furthermore, the dust generated when the spikes scrape the road surface is harmful to the human body. There is a move toward a complete ban on the use of spiked tires due to the impact There is. Therefore, many solutions have been disclosed to date, such as , described in Utility Model Application Publication No. 1983-34004, Publication No. 174906-1980, Publication No. 63-69605, etc. There is something like that.

0004 To briefly explain these, The one described in Utility Model Publication No. 60-34004 is a spike head and a spa embedded in the tire. The spike legs are removable, allowing you to replace worn spike heads with new ones. It was made so that it could be done. The device described in Japanese Utility Model Application Publication No. 174906/1986 has a locking mechanism provided on the protrusion of the spike support plate. Spikes can be attached by combining them and engaging protrusions provided in the mounting holes formed in the tire. The spike support plate is removable across the width of the tire. The one described in Utility Model Application Publication No. 63-69605 has bolts and spike pins buried in the tire. The spike pin is connected with a screw, and by rotating this spike pin, the tire can be removed. It protrudes and fits in.

[0005]

[Problem that the idea aims to solve]

However, the above-mentioned conventional type uses spiked tires as regular tires. When using the spike pin, the tip of which protrudes from the ground surface, should be attached to the tire base. It is either removed from the body or pushed inside the tire body. Therefore, A new hole has been formed in the ground area where the spike pin was previously protruding. , and the area of the effective ground plane decreases. This reduction in contact area is due to This impairs the performance of the tire, and may cause damage when driving in the rain, at high speeds, or when making sharp turns. There were problems such as a decrease in safety.

[0006] Furthermore, conventional tires have two types of tires: regular tires and spiked tires. Since it is possible to change only the type, various tire contact surfaces (for mud, (e.g. sand use) could not be changed.

[0007] The applicant has proposed Utility Application No. 2-38772 as a solution to these problems. By making it possible to selectively replace part of the tire contact patch, it is possible to adapt to the various road conditions mentioned above. We have disclosed a tire that can be used in all seasons. However, this all-sea With tires for commercial vehicles, each part that needs to be replaced has a small proportion of the total contact area of the tire. Because of the small size, it is difficult to secure sufficient ground contact area depending on the road conditions, and Each grounding member requires a large number of grounding members, and the installation work is time-consuming. I discovered that there was a problem.

[0008] Therefore, in this invention, the entire concave area of approximately the width of the ground formed in the tire contact area is made to reflect the road surface condition. By selectively installing ground contacting materials according to the The purpose is to provide an all-season tire that can be used in the following situations.

[0009]

[Means to solve the problem]

The all-season tire of the present invention has a concave portion approximately in contact width formed on the tire contact surface. A mounting member is provided on each of the tires, with its base fixed to the tire. The mounting material is a grounding material selected according to various road conditions, such as screw connection. By attaching it in a removable state, it is possible to close the recess with the grounding member. In addition, this ground contact member is used as part of the tire contact surface. Furthermore, one of the bottom surface of the recess and the back surface of the grounding member is provided with a recessed portion, and the other is provided with a convex portion. A shaped part is formed, and the concave part and the convex part are attached in an engaged state. It is something.

0010

[Effect]

By attaching the grounding member to the mounting member whose base is fixed to the tire, The grounding member is integrated with the tire via the mounting member, and when this tire is used, When the surface of the grounding member is in contact with the road surface, the selected grounding member is functional. ing. Furthermore, the bottom surface of the concave portion and the back surface of the grounding member are individually formed with a concave portion and a convex portion. By engaging with the shaped part, the ground contact member will not touch the tire body while the tire is in use. Prevents it from shifting.

[0011]

【Example】

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. In the figure, Reference numeral 1 denotes a tire body, and its contact surface has a recess 1a having a bottom surface 1b having a width approximately equal to the width of the tire. A plurality of grooves are formed at intervals equal to, for example, the circumferential length of the tire contact surface divided into eight equal parts. Reference numeral 2 denotes a mounting member, and a base portion 2a is fixed to the tire body 1. 3 is a grounding member, which is fitted into the recess 1a with the back surface 3b in contact with the bottom surface 1b. It has a plurality of holes 3a. 4 is a member to be mounted, which is provided at the lower part of the hole 3a and is screwed to the mounting member 2; It can be attached and detached depending on the situation. 5 is a spike pin embedded so as to protrude from the surface of the grounding member 3.

0012 Here, the grounding member 3 is fitted into the recess 1a of the tire body 1, as shown in FIG. and operate the attached member 4 from the hole 3a with a hex wrench etc. to remove each attached part. By attaching the material 4 to the mounting member 2, it becomes integrated with the tire body 1. That's what I do.

[0013] At this time, as shown in FIG. 2, the bottom surface 1b of the tire body 1 is formed into a corrugated shape, and The back surface 3b of the ground contact member 3 is formed into a waveform that matches the waveform of the bottom surface 1b, and the tire body is Even if the ground contact member 3 is prevented from shifting relative to the tire body 1 when using the tire body 1, good. This locking means includes recesses in each of the bottom surface 1b and the back surface 3b, in addition to those shown in the drawings. , one that provides a convex part and locks by engaging these parts, and one that has a convex part and locks the bottom surface 1b and the back surface 3b. A separable adhesive is inserted between the two to lock them together using adhesive force. .

[0014] Next, the grounding member 3 is installed in the recess by removing the attached member 4 from the mounting member 2. 1a, and has the same tread as the contact surface of the tire body 1 shown in Figure 1. Instead of the grounding member 3 having a dotted pattern, for example, the surface can function as a snow tire. A grounding member with a Grounding members of various shapes, such as a compact grounding member 3, can be attached.

[0015] In addition, in the illustrated one, the mounting member 2 and the mounted member 4 are screwed together. However, it is not limited to this, and various methods such as engagement between a convex part and a concave part can be used. can be used.

[0016] Further, the recess 1a formed in the tire body 1 is formed in the tire body 1 as shown in FIG. , and is long in the circumferential direction of the tire body 1, and both ends of the recessed portion 1a are approximately the width of the tire. They may be formed so as to converge to one point. At this time, the recess 1a has the above-mentioned housing. Attachment members 2 are provided at two locations on the part to be bundled. Therefore, the grounding member 3 is concave. It is formed to correspond to the shape of the portion 1a, and is mounted so as to correspond to the mounting member 2. A hole 3a having an attaching member 4 is provided.

[0017]

[Effect of the idea]

This invention has various ground contact areas in each of the recesses of approximately ground contact width formed on the tire contact surface. Since the materials are installed selectively, each Change to a tire contact surface (for mud, sand, etc.) with sufficient area according to the road conditions of the species. Furthermore, since the parts to be replaced are large, the cost of each tire is There are fewer parts to replace, especially when large vehicles such as trucks have a large number of tires. Also, when the tire itself is large, the time required to replace the ground contacting parts can be shortened. be able to.

[0018] In addition, since the back side of the grounding member is locked to the bottom of the recess, the grounding member is attached to the tire. It prevents it from shifting against the main body and ensures that the ground contact member and the tire main body are integrated. I can.
