  The present invention relates to a chair leg cover used on a chair leg, and more particularly to a chair leg cover excellent in versatility that can be attached to chair legs of various shapes and sizes.

  If a chair with legs is installed directly on the floor, the floor may be damaged by the friction between the chair legs and the floor when the chair moves while standing up or sitting on the chair. In order to prevent such inconvenience, a chair leg cover made of rubber or the like is often attached to the leg of the chair.

A conventional chair leg cover is formed in a bottomed cylindrical shape that matches the shape and size of a chair leg (see, for example, Patent Document 1 below).
However, such a conventional chair leg cover has a problem that if the shape and size of the conventional chair leg cover do not match the shape and size of the chair leg, the chair leg cover can easily come off the chair leg.
Therefore, if the user owns a chair having legs of various shapes and sizes, the user must select a chair leg cover having a shape and size suitable for each chair leg, which is very troublesome. It is.
In addition, there is a possibility that a chair leg cover with a desired shape and size cannot be found in a store with a small assortment of goods, especially when the leg shape is a special shape other than a general circle or square. There is a high probability that a chair leg cover that matches the shape of the chair will not be found.
Also, if a wrong size product is purchased, it cannot be attached to the leg, or even if it is attached, it may come off easily.

  Furthermore, the conventional bottomed cylindrical chair leg cover is bulky when stored in a warehouse or transported to a store, and therefore requires a large space in a warehouse for storage or a container for transportation, etc. There was also a problem that the transportation cost was high.
