DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire cover to be mounted on a tire of a vehicle when the vehicle travels on a floor such as a warehouse or a factory floor.

[0002]

2. Description of the Related Art Conventionally, when a work vehicle or the like travels on a floor that does not want to be stained, such as a floor in a warehouse or a factory, or a floor of an indoor stadium, the vehicle travels at as low a speed as possible. This avoids tire marks and scratches on the floor. However, in practice, at the time of starting, stopping, turning, etc., it is inevitable that the floor surface will have some traces of tire slip or scratches due to pebbles etc. entering the tire groove. . The work vehicle described above is, for example, a vehicle for working at heights, a large RV vehicle, or the like. In particular, a tire for a vehicle for working at heights is a solid tire having a large weight, and a groove of a tire pattern recessed on an outer peripheral surface of the tire becomes deeper and wider.

[0003]

Conventionally, in consideration of the circumstances described above, tires dedicated to traveling on premises have been developed as disclosed in Japanese Patent Application No. 61-234473. The above-mentioned tires for indoor vehicles are intended to avoid the occurrence of tire slip marks during running by removing carbon black from the rubber composition constituting the tire.

[0004] However, if the work vehicle is used exclusively for the premises, the above-mentioned tires dedicated to the premises may be kept mounted. However, normally, a work vehicle working on an outdoor road or the like is temporarily used in the premises. In such a case, it is necessary to enter the premises with the normal tires as it is, or to spread a rubber mat or the like on the movement route, or to change from the normal tires to the tires dedicated to the premises, which is very troublesome.
Also, if it is necessary to go out on an outdoor road from the state where the tire dedicated to the campus is installed, it is necessary to change from the tire dedicated to the campus to the normal tire,
This was also troublesome.

In view of the circumstances described above, the applicant of the present application mounts a tire cover that does not cause slip marks on the outer peripheral surface of a normal tire, so that the tire can be easily mounted, and the tire can be mounted while traveling. Proposed a tire cover for floor running that protects the floor surface from slip marks and abrasions (Japanese Patent Application Nos. 9-224917 and 10-36316).
No., Japanese Patent Application No. 10-36317). In addition, when it is necessary to run on an outdoor road once from the state where the tire dedicated to the premises is mounted, the tire cover is attached to the tire dedicated to the premises, so that the tire dedicated to the premises is grounded. It is very convenient because you can run without contact.

As shown in FIG. 11, the above-described floor traveling tire cover 100 has a tire cover body 1 having a substantially band-like outer shape formed by assembling a wire 101 'made of rubber in a mesh pattern.
01 is molded. The rubber material constituting the tire cover body 101 is formed from a rubber material colored in an inconspicuous color such as light gray by removing carbon black that causes slip marks, and even if a slip mark is attached, Care has been taken to make the marks less noticeable.

At the inner and outer side edges of the tire cover main body 101, hook portions 102 and 103 formed in a substantially U-shape are formed at regular intervals in the longitudinal direction of the main body 101 so as to protrude. The fastening ropes 10 along each hook 102
4 and fixing portions 103 on the outer side of the tire.
Is fixed by caulking a latch 105 for latching the rubber band d.

When the floor traveling tire cover 100 configured as described above is mounted on the tire C, the tire cover body 101 is wound around the outer periphery of the tire C, and then is mounted on the tire C.
Rope 1 provided along each hooking portion 102 on the inner edge of the
By connecting the connecting tools 104a and 104b at both ends of the tire cover 04, the inner portions of both ends of the tire cover main body 101 are connected and tightened. A connection hook 1 attached and fixed to an outer hooking portion 103 'at one end of the tire cover main body 101.
06 to the hook 10 at the other end of the tire cover body 101.
The outer portions of both ends of the tire cover main body 1 are connected by being hooked on 3 '. Next, the tire cover main body 101 is attached to the tire C by stretching the annular rubber band d to each of the hooks 105 attached and fixed to each of the hooks 103 provided along the outer edge of the tire cover main body 101 while extending.
And attached as shown in FIG.

By mounting the above-mentioned floor traveling tire cover 100 as described above, the outer peripheral surface of the tire C and the floor surface B are maintained in a non-contact state during traveling of the vehicle. In addition, the tire slip mark does not reach the floor surface, and functions without any problem in most use situations. However, when the above-mentioned tire cover 100 is mounted on an aerial work vehicle mounted with a heavy solid tire, there is no problem within a normal traveling range. A particularly excessive load is applied to the grounding surface of the main body 101 and the edges on both the inside and outside.

As described above, when an excessive load is applied to the ground contact surface and the inside and outside sides of the tire cover body 101, the contact surface portion, the edges of the inside and outside both sides, the hooks 102,
103 may be greatly deformed so as to be greatly twisted or displaced, and the mesh pattern forming this portion is deformed, and the shoulder portion on the outer peripheral surface of the tire C protrudes from the deformed mesh and contacts the floor B. However, slip marks due to the tire C may adhere to the floor surface B (FIG. 13).

Also, as described above, the tire cover body 1
When a large load is locally applied to the tire cover 01, the tire cover main body 101 may be deformed so as to widen the connection portion between both ends, and a gap may be generated. There was also a possibility that the outer peripheral surface of the metal was exposed to come into contact with the floor surface B (FIG. 14). In addition, the phenomenon described above is caused by insufficient rigidity of the inner and outer sides of the tire cover main body 101,
And insufficient adhesion of the tire cover body 101 to the outer peripheral surface of the tire c.

An object of the present invention relates to a floor running tire cover as described above, in which the tire cover body is twisted or displaced and the tire protrudes from a mesh or a connection portion of the tire cover body and comes into contact with the floor surface. The reason is to prevent this reasonably.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 5 show a floor traveling tire cover. The floor traveling tire cover A is, for example, wound around the outer periphery of an outdoor tire C mounted on a work vehicle when traveling on a floor surface B in a warehouse or a factory, for example, so that the tire is mounted. This prevents the C from directly contacting the floor B and prevents the tires C from slip marks or the like from adhering to the floor B (FIG. 7).

The floor traveling tire cover A is provided with a tire C
The tire cover body A ′ has a substantially belt-like outer shape and a mesh pattern so as to be wound around the outer periphery of the tire cover body A ′. The tire cover main body A ′ is configured by dividing the main body a into five main units a by dividing at predetermined intervals in the length direction, and connecting the divided portions of each main unit a. I have. That is, the tire cover main body A ′ is configured to have the above-described substantially band-shaped outer shape by sequentially connecting the five main body units a. The tire cover main body A 'has a fastening rope 2 attached along the inside thereof, and connection buckles 4a and 4b are attached to both ends of the fastening rope 2 (FIG. 1).
Note that the tire cover main body A ′ shown in FIG. 1 does not show an intermediate portion.

As described above, each of the body units a constituting the tire cover body A 'is a wire a' having a high-tensile core material 1a such as a synthetic fiber, a wire, or a glass fiber provided inside a rubber material. Is formed into a mesh-shaped pattern as shown in the figure and integrally molded to form a substantially rectangular outer shape having a length of about 1/5 of the above-described tire cover main body A '(FIG. 2A). . That is, the main unit a
Are molded in the same shape, so that all five sheets have the same shape. Further, the main unit a has an inner edge portion and an outer edge portion formed in a substantially zigzag shape corresponding to the outer shape of the mesh pattern, so that a hook portion protruding substantially in a mountain shape along these inner and outer sides. Projections 1b and 1c are formed at regular intervals. Further, at one end edge and the other end edge of the main unit a, joining edges a1 and a2, which are sufficiently thicker than the wire a 'constituting the mesh, are formed in a slightly curved shape.

The openings of all the meshes of the mesh pattern constituting the main unit a are covered with a covering plate a3 so as to be covered. The covering plate a3 has an appropriate thickness,
For example, it is a thin plate member having a thickness of about 2 mm, and is integrally formed so as to cover the openings of each mesh when forming the main unit a. The cover plate a3 is flush with the back surface of the main unit a (FIG. 2B). still,
In the case of the present embodiment, the thickness of the wire a 'constituting the mesh pattern of the main unit a is set to about 10 mm. Further, the thickness of the wire or the cover plate may be arbitrarily changed (FIGS. 3 to 5).

The covering plate a3 has a function of covering the inside of the mesh of the mesh pattern, thereby effectively improving the rigidity of the mesh and preventing the mesh from being twisted or displaced during traveling. Further, since the cover plate a3 is flush with the rear surface of the main unit a, the contact area of the rear surface of the tire cover main body A ′ with the outer peripheral surface of the tire C increases, and the outer peripheral surface of the tire C is By increasing the frictional force generated between the main body A 'and the main body A', it is possible to effectively prevent the displacement generated between the two. In order to increase the frictional force generated between the back surface of each of the main units a and the outer surface of the covering plate a3, a fine uneven pattern for preventing slippage may be formed. .

A circular opening 5 is formed at the center of each covering plate a3 formed so as to cover each mesh opening of the main unit a as described above. As described above, the openings 5 formed in the respective cover plates a3 are used because the cover plate a3 and the mesh are appropriately deformed by an external force generated when the tire cover body A ′ is wound around the tire C and the like. And is formed as a perfect circular hole in the center of each covering plate a3 (FIG. 2).

By the way, in the state where the inside of each mesh of the mesh pattern is covered with the covering plate a3 as described above, the rigidity of the main unit a is increased to a slightly excessive degree. By opening the opening 5, the rigidity of the mesh of each part can be maintained as necessary, and a suitable deformability can be provided. As a result, the tire cover body A 'is wound around the outer periphery of the tire C. In this case, it is possible to maintain good mounting properties. The size and shape of the opening may be arbitrarily changed according to the required deformability. In addition, the size and shape of the opening to be opened as described above may be changed in accordance with the location of the mesh of the main unit a, and the main unit a is formed by partially connecting the mesh without the covering plate a3 as described above. You may make it exist. That is, the cover plate a3 may be provided on part or all of the mesh of the tire cover body A '.

Further, depending on the work place, the user may temporarily go outdoors during the movement, but if it is raining at this time, a gap between the outer peripheral surface of the tire C and the tire cover body A 'may occur. Rainwater may enter the area. However, in such a case, the opening 5 also has a function of quickly draining rainwater that has entered between the outer peripheral surface of the tire C and the tire cover body A ′.

The left and right side edges of the main unit a formed in a substantially zigzag shape corresponding to the outer shape of the mesh pattern as described above are formed inside the recesses a6 formed in the substantially zigzag side edges at the substantially zigzag side edges. A thin plate-shaped adherend plate a4 is formed integrally along (FIG. 2). The attachment plate a4 enhances the shape-retaining property of the side edge of the main unit a formed substantially in a zigzag shape, and, when the main unit a is wound around the outer periphery of the tire C, the vicinity of the shoulder portion of the tire C This prevents the shoulder portion of the tire C from being exposed from the concave portion a6 of the zigzag side edge and coming into contact with the floor surface as described above. In the case of the present embodiment, the concave portion a6 is used. (See FIG. 2). Further, the thickness of the adherend plate a4 in this embodiment is set to about 2 mm, but the thickness and the outer shape may be arbitrarily changed as long as the functions described above can be exhibited. In the present embodiment, the adherend plate a4 is provided along the left and right side edges of the main unit a. However, the adherend plate a4 extends along one of the inner and outer side edges of the main unit a. May be provided.

The joining edge a1 at one end of the main unit a
The tongue piece a5 is extended along (FIG. 2). The tongue piece a5 connects the divided portions of each body unit a to face each other, and when forming the tire cover body A ′, creates a gap generated between the joining edges a1 and a2 of the adjacent body units a on the back surface. It covers from the side (FIG. 1). When the tongue piece a5 is wound around the outer circumference of the tire C and the tire cover main body A 'is wound and mounted, the tongue piece a5 is a joint edge a2 portion on the other end side of each main body unit a facing each connection portion of the tire cover main body A'. It is inserted between the back surface and the outer periphery of the tire C. The width dimension of the tongue piece a5 is set so as to substantially match the width of the ground contact surface of the tire C. In the present embodiment, the thickness of the tongue piece a5 is set to about 3 mm. However, the thickness of the tongue piece may be arbitrarily changed, and the thickness may be reduced gradually toward the leading edge.

The rubber material constituting the above-mentioned main unit a is a composition excluding carbon black which causes slip marks, and examples of the composition used in the present embodiment are shown below.

Can be increased to prevent displacement between the two.

As described above, a circular opening 5 is formed at the center of each covering plate a3 formed so as to cover the opening of each mesh. The opening 5 is for allowing the cover plate a3 and the mesh to be appropriately deformed by an external force generated when the tire cover body A2 'is wound around the tire C and the like. That is, the above-described floor traveling tire cover A2 is integrally formed without dividing the tire cover main body A2 ', but has the same effect as the above-described floor traveling tire cover A. Also, the above-described floor traveling tire cover A2 does not divide the tire cover main body unlike the above-mentioned floor traveling tire cover A, so the storage form is somewhat large, but there is no connecting portion, so that the strength is high. Is advantageous.

Since the tire cover bodies A 'and A2' are colored light gray as described above, the slip marks of the tire cover bodies A 'and A2' adhere to the floor B during the work. However, the tire C is not so noticeable as a black mark like the slip mark of the tire C, and is almost invisible. The floor traveling tire covers A and A2 are mounted on the tire C that travels on a normal road outdoors and used outside the premises. It can also be used when it is necessary to drive out of the road. In this case, by mounting the floor running tire covers A and A2 on the premises dedicated tire in the same manner as described above, it is possible to travel on an outdoor road without bringing the premises dedicated tire into contact with the ground. It is possible to prevent scratches and dirt from getting on the tire. After traveling on an outdoor road with the floor running tire covers A and A2 attached as described above, the floor running tire covers A and A2 should be cleaned thoroughly in preparation for the next indoor use. It is necessary to remove dirt and small gravel.

Incidentally, the tire cover bodies A 'and A2' in the above-described embodiment are formed of a substantially rhombic mesh in a continuous mesh pattern.
2 ′ may be any mesh pattern, as long as the outer peripheral surface of the tire C and the floor surface B can be kept in a non-contact state, and the shape, size and thickness of the wire rod may be used. , Wall thickness and the like may be arbitrarily changed.

The main unit a of the floor running tire cover A and the tire cover main body A2 'of the floor running tire cover A2 are provided with a high-tensile core 1a inside a rubber material and a wire a'. Reinforced. However, traveling with the floor traveling tire covers A and A2 attached is only to slowly move on the floor surface B, so that the strength of the main body unit a and the tire cover main body A2 'has room. Therefore, the number of the high tension cores 1a can be reduced or omitted. Further, the main unit a of the floor covering tire cover A and the tire cover body A2 'of the floor covering tire cover A2 are made of a rubber plate having short tensile fibers, such as aramid fibers, mixed therein to increase the tensile strength. It may be formed into a shape similar to the above-described tire cover body by punching and molding. The rubber material may be a rubber material that does not contain aramid fiber as it is,
It can be used without any problem in strength. Further, the main body unit may be made of a material that does not easily cause slip marks, such as a synthetic resin material such as urethane and PVC, in addition to the rubber material.
