[Conventional technology]

Traditionally, it has been used to remove dust adhering to the soles of shoes, etc., and prevent it from entering the room. It is a common practice to place shoe-wiping mats at entrances to rooms, entrances, etc. As shown in FIG. 4, this shoe cleaning mat has a base fabric 11 and pile cord threads 12 is tufted, an elastomer backing 13 is applied to the back of the base fabric, and the tip of the pile yarn is 14 cut or left in a loop shape are used. Also, flooring Floors that are commonly used as soft floors (generally carpets) or similar) and hard floors (vinyl chloride tiles, P-tiles, (terrazzo marble, etc.), but mats that move a lot, especially shoe-wiping mats, are In this case, when the pile cord thread is stepped on and laid down, it Since there is a certain direction in which you sleep, when walking on the mat, the pile yarn The problem is that the mat moves on the floor while the person repeatedly sleeps and wakes up. cause problems.

0003 To prevent this, various fixing devices have been proposed for fixing the mat to the floor. ing. Fixing tools for mats can be roughly divided into flat-shaped ones and three-dimensional ones with uneven surfaces. The shape is known. An example of the former is an adhesive film such as double-sided tape. Examples of the latter include plastic molded into various uneven shapes. It will be done.

0004

[Problem that the idea aims to solve]

The former adhesive film is an effective means of adhesively fixing flat surfaces together. However, it is not necessarily effective for fixing non-flat items such as mats, If lint or dust adheres to the adhesive, the adhesive strength will decrease significantly and the adhesive strength will not recover. There is a problem that the usable life is short. In addition, in the case of an uneven shaped molded object, the locking surface This is intended to prevent the mat from moving by increasing the frictional resistance between the mat and the mat. However, if the floor is a hard floor such as vinyl tile or concrete, Not only is the fixation not performed effectively, but also dust may adhere to the locking surface. However, there is a problem in that the frictional engagement force is significantly reduced.

[0005] In addition, shoe-wiping mats are loaned to customers for a limited period of time, and the mats are removed after use. It is operated using a rental system that collects, washes and regenerates it, and then rents it out to users again. However, when installing rental mats, the working time per It is important to reduce costs by shortening the mat and fixing it to the floor surface. It is desirable to be able to easily set the equipment is required.

[0006] Therefore, the purpose of the present invention is to use mats, especially shoe-wiping mats, to clean floors, especially hard floors. It is possible to firmly adhesively fix it to the lower part, and this adhesive strength also prevents thread waste. Even if the adhesive strength decreases due to adhesion of dirt or dust, it is easy to recover and can be used repeatedly. To provide a fixing device for the mat that can be used for various purposes.

[0007]

[Means to solve the problem]
