SOLUTION: This entrance mat is characterized by laminating and integrating a reinforcing cloth on at least a part or the whole of an edge rubber part so as to be nipped. The repairing method comprises putting a repairing lining rubber sheet having a reinforcing cloth nipped on the reverse side over the damaged part of the edge rubber part of the existing mat so that the reinforcing cloth is laminated on the edge rubber part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents cracks that occur in a rubber portion of a mat edge, and prevents the rubbers from coming off due to the cracks even if a crack occurs. The present invention relates to a door mat that can be used as a door mat, and a repair method that exhibits the same effect as the door mat when a crack or a defect occurs in an edge rubber portion of an existing mat.

[0002]

2. Description of the Related Art Conventionally, rubber mats (mostly integral type but partially including a separate type) used as entrance mats are mainly used as rental products which are regularly replaced by rental companies. Yes, the rental agent prepares and transports a new mat that has been cleaned,
Used mats are collected one by one and new mats are laid, and the old mats brought back are sent to their own cleaning factory or a specialized cleaning company to make new mats that have been cleaned and used repeatedly. I am trying to do it. In such a cycle, the rubber sheet part deteriorates to a considerable extent due to the influence of ozone.However, the method of storage during transportation and storage by the rental contractor is in a state where the mat is folded, and cleaning is performed. Due to large physical effects such as twisting of the mat in the washing machine and collision of the mats at the time, the peripheral portion of the folded rubber sheet (edge rubber portion), for example, in the case of a mat folded in two at the time of storage, the longitudinal direction of the mat In the center, in the case of three folds, cracks occur at one-third and two-thirds positions, and slight cracks crack and result in a mat with no commercial value. Since the period is much shorter than the original useful life, it is a very big problem for the trader and it has a commercial value as much as possible. Has been desired is possible to extend the period as that mat.

[0003]

As a countermeasure against ozone, a method of protecting a rubber sheet by forming a film by putting waxes and a plasticizer (POP or the like) in rubber and causing it to bloom has been adopted. However, if the wax or the like for blooming disappears, the protective film naturally disappears, so that it cannot be said to be a countermeasure thereafter. or,
The method of attaching an ozone-resistant film (such as a PVC film) to the bottom of a rubber sheet loses its inherent properties, such as slipperiness and reduced flexibility.
There was a disadvantage that it was not suitable as a door mat. Similarly, there is a method in which an ozone-resistant substance is mixed into rubber, but it is not suitable for a door mat, such as being too hard in cold weather, lacking flexibility, and being hard to return to its original state. Further, it is conceivable to simply prevent the cracking phenomenon by using a rubber mat having good elongation and excellent flexibility, but this does not fundamentally solve the problem. In any case, in rubber mats used as entrance mats, the best countermeasures to prevent the above-mentioned cracks have not been devised.

The present invention has been made in view of the above points, and it is possible to prevent cracks or cracks generated by factors of ozone and external pressure in a peripheral portion of a mat, that is, a rubber edge portion, and even if cracks are generated. It can be used as a completely normal state by preventing the rubbers from separating from each other, and it does not impair the original function of the rubber mat, and it is easy to fold etc. so that it is convenient for transportation etc. The primary purpose is to provide a doormat that has sufficient flexibility, and in the case of a conventional doormat that has already been damaged, it prevents damage again and looks beautiful even if cracks occur It is a second object of the present invention to provide a repair method that can further extend the commercial value of the entrance mat.

[0005]

According to the present invention, there is provided an entrance mat according to the present invention, comprising:
When the mat body is molded by the slightly larger back rubber sheet forming the back rubber portion and the peripheral rubber sheet forming the edge rubber portion, at least a part or the whole of the edge rubber portion is sandwiched by the reinforcing cloth. The reinforcing cloth is laminated so that the members are integrally adhered to each other. In addition, in the case of an existing entrance mat in which the edge rubber portion is cracked or partially missing, the cracked portion is bonded or missing portion. A rubber piece for repair is adhered to the backing, and a backing rubber sheet material for repairing with a reinforcing cloth sandwiched on the back side is layered, and the reinforcing cloth is repaired in a state in which the reinforcing cloth is laminated at the edge rubber portion. It is characterized by doing.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged sectional side view showing an embodiment of the present invention, and FIG. 2 is a perspective view showing an example of a laminated state of each member.

In the drawings, reference numeral 1 denotes a base cloth, which is a conventional base cloth in which pile yarns are implanted, and a rubber mat which can be used as a door mat or the like by integrating a back rubber sheet 20 on the back surface side. It is a member for making. Back rubber part 2
Is formed by a back rubber sheet 20 which is slightly larger than the base cloth 1, and at a portion protruding from the base cloth 1, that is, at a peripheral portion of the back rubber sheet 20, the peripheral rubber sheet 30 is laminated and edge rubber The part 3 is formed. The backing rubber portion 2 and the edge rubber portion 3 are mixed with an ozone-resistant substance in consideration of the fact that the essential function of the entrance mat, which is a major point of the present invention, is not reduced, that is, the property of the rubber is not changed. Instead, it is designed to be as flexible and stretchable as possible, and by adding wax and the like, it is devised to provide an optimal rubber sheet for door mats.

Reference numeral 4 denotes a reinforcing cloth for preventing cracks and cracks from being generated at the peripheral portion of the entrance mat, and even when cracks are generated, the cracks are not conspicuous when the mat is laid, and are used as ordinary products without impairing the appearance. It is a member for making it possible. The material of the reinforcing cloth 4 is not particularly limited, but the rubber sheet is clogged with the reinforcing cloth 4 in a state where the reinforcing cloth 4 is sandwiched by vulcanization molding, so that a reliable reinforcement can be achieved. It is considered that a thin woven fabric having an appropriate coarseness is preferable in consideration of the fact that folding and the like can be freely performed with flexibility along the line. The range of the reinforcing cloth 4 is at least a portion where cracks and cracks are likely to occur (only a central rubber portion in the longitudinal direction of the mat in the case of a mat that is folded in two at the time of storage) or a rubber portion in the longitudinal direction of the mat (FIG. 2) Or, it is conceivable to sandwich the entire area of the edge rubber portion of the mat, and further, the entire area of the back rubber portion 2 of the mat. It should be considered depending on the material and the like, and it should not be specified to any one.

Therefore, in the case of the existing entrance mat 10, as shown in FIG. 4, the cracked state in the edge rubber portion 13 can be visually recognized as it is, and it has no value as a rental product. Of course, in the case of the entrance mat,
Cracks and cracks are unlikely to occur, but even if cracks occur, the rubber can be laid out as a clean mat by the reinforcing cloth 4 in a state where the rubbers are in contact with each other without detaching (Fig. 3). Thus, the value as a product can be maintained or prolonged.

Next, a repair method according to the present invention when the edge rubber portion 13 is cracked in the existing entrance mat 10 will be described. First, the cracked portion may be adhered with an adhesive, and then the backing rubber sheet material 5 for repair may be overlaid on the backing rubber portion side of the back surface (FIG. 5). , That is, a state in which the reinforcing cloth is laminated on the edge rubber portion, and an effective mat is provided as a countermeasure against cracks thereafter. In addition, when repairing was performed only by bonding a cracked portion or using only a rubber material, cracking and the like often occurred again, and it was hard to say that the treatment was excellent. The repairing backing rubber sheet material 5 is a material in which the reinforcing cloth 6 is placed in a sandwiched state to further enhance the adhesion of the reinforcing cloth 6, that is, the upper layer of the backing rubber sheet material 5 through the eyes of the reinforcing cloth 6. And the majority of the lower layer are connected to each other, and the reinforcing cloth 6 itself is positioned as a part of the rubber sheet material. It can be part of a part. The edge rubber portion 13 as shown in FIG.
In the case where a partially missing portion 13a is formed, a clean notched portion 13b is formed by appropriately cutting as shown in FIG. 6B, and a repairing rubber piece 7 having the same shape as shown in FIG. The back rubber sheet material 5 for repair is adhered to the back side as shown in FIG.
And the reinforcing cloth 6 may be reinforced and repaired in a state in which the reinforcing cloth 6 is laminated on the edge rubber portion 13.

[0012]

As described above, according to the present invention, a two-stage preparation which is completely unthinkable in a conventional entrance mat is provided, that is, cracks and cracks are minimized. Even if cracks and cracks occur next, it is devised so that it is not apparent that it is occurring on the appearance, and the main entrance mat impairs the function of the mat itself Therefore, it can be said that the product of the present invention has a very excellent commercial value as a rental product, and the repair of existing mats is exactly the same as the product of the present invention described above. By making the structure, tough reinforcement is achieved, it can be used for a longer period than before, and the effect is extremely high for mat rental companies. It can be said that.
