Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flooring material for renovation that can be easily pasted on a floor of a building such as a house without peeling old carpets and carpets and without using an adhesive.
[0002]
[Prior art]
Conventionally, when remodeling the floor of a building such as a house, when replacing the floor from a carpet or carpet to a wooden floor, the old carpet or carpet is removed by stripping it once, and the floor base material below it is adjusted smoothly. After repairing, a new flooring was pasted on top of it. In general, the floor material is attached to the floor base material by using an adhesive or, in some cases, using a nail or a staple. Further, as a simple construction method that does not use adhesives, nails, staples, etc., a conventional surface fastener using a hook-like engagement element and a loop-like engagement element (JP-A-4-194167, JP-A-3-202551). No. 1) and brushed fasteners (Japanese Patent Laid-Open No. 10-102730) are disclosed.
[0003]
[Problems to be solved by the invention]
However, the work of replacing the floors from carpets and carpets to wooden floors as described above is not only laborious and labor-intensive to remove old carpets and carpets, but the floor base material after peeling is old. If the adhesive remains without being removed, or if the carpet or carpet is forcibly removed, the smoothness of the surface of the floor base material may be lost or, in severe cases, the surface of the floor base material may be damaged.
[0004]
Also, after removing the old carpet, re-attaching the new flooring is not only a time-consuming and labor-intensive work, but if the floor base material surface is damaged, it should be applied smoothly without unevenness. Was a difficult technique.
[0005]
Further, the hook-and-loop fastener disclosed in JP-A-4-194167 and JP-A-3-202551 has a fixing force only after combining two types of engaging elements, a hook-shaped engaging element and a loop-shaped engaging element. 2 types of engagement elements, that is, a hook-like engagement element attached on the floor base material and a loop-like engagement element attached on the back surface of the floor material are attached. When the position interval is the same and parallel to each other, and the flooring is pasted on the floor base material, it is necessary to match the positional relationship between the two. Therefore, the fixing force is halved unless the engagement element is attached with very high accuracy. Moreover, it took a lot of time and labor to improve the accuracy of sticking, and the construction cost was high. Moreover, in order to give the flooring soundproofing performance, it is necessary to attach a sound insulating cushioning member between adjacent surface fasteners, which is also very disadvantageous in terms of cost. The same applies to the other raised fastener disclosed in JP-A-10-102730.
[0006]
An object of the present invention is to provide a flooring material for renovation that can be applied to a flooring very easily without peeling off an old carpet or carpet when the floor is replaced from a carpet or carpet to a wooden floor. is there.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a flooring material for reforming according to the present invention is a flooring material for reforming provided with fitting protrusions and fitting grooves that can be fitted to each other on opposite sides of a plate-like substrate. In addition, there is an inverted hook-shaped locking portion that is entangled with the pile at the tip of a projection portion having a predetermined length that is inserted into a pile such as a carpet or carpet all around the back surface of the plate-like substrate. The provided locking member is provided , and an inner space is formed on the back surface of the plate-like substrate by the lock members provided around the entire back surface of the plate-like substrate .
[0008]
From such a configuration, when the back surface of the plate-like substrate is pressed onto a carpet or carpet, the protrusion of the locking member provided on the back surface of the plate-like substrate is stabbed into a pile such as a carpet or carpet. An inverted hook-shaped locking portion provided at the tip is entangled with the pile such as the carpet or carpet, and the plate-like base material is crimped and fixed onto the carpet or carpet. Further, since the inner space is formed on the back surface of the plate-like base material by the locking members provided around the entire back surface of the plate-like base material, the inner space is formed with an insect repellent and an ant-proofing agent. It can be used as a place for installing a fungicide or a desiccant, or a place for applying a synthetic resin emulsion containing a tree essential oil component.
[0009]
Further, the locking member provided on the back surface of the plate-like base material has a length of the protrusion of 1.0 mm to 5.0 mm and a length of the reverse hook-shaped locking portion of 0.5 mm to 3.0 mm. Preferably there is.
[0010]
When the length of the protruding portion of the locking member is 1.0 mm to 5.0 mm, the protruding portion is placed in the pile of the carpet or carpet when the back surface of the plate-like substrate is pressed onto the carpet or carpet. If it is deeply and reliably inserted, and the length of the reverse hook-shaped locking portion is 0.5 mm to 3.0 mm, the reverse hook-shaped locking portion that is embedded in a pile such as a carpet or carpet is a carpet. The plate-like base material firmly entangled with a pile such as carpet or carpet is more securely fixed by pressure on the carpet or carpet.
