Description

STRUCTURE FOR ROUNDING A CORNER OF WALLS

TECHNICAL FIELD

The present invention relates to a structure for rounding a corner of wall; more particularly, a structure for rounding a corner in the interior wall of building, which can close easily the space of contact regions in between a wall and a wall, a wall and a ceiling, a wall and a floor and the like.

BACKGROUND ART

Corners are made necessarily in contact regions of 2 faces or 3 faces on interior walls of most buildings. That is to say, a building has at least twelve recti-linear corners (equivalent to sides of hexahedron) and eight apex corners (equivalent to apexes of hexahedron) even in the simplest constructure since its inner space usually corresponds to a hexahedron .

Generally, the corners are liable to be contaminated with alien substances such as dust and the like and become a habitat for every kind of insects, bacteria and fungi frequently. In detail, the corners have a spatial feature of contact points that is formed while a wall and a wall, one or two walls and a floor or a ceiling are met and is difficult to be approached, which has been called as " corner effect ". Thus, the corners cause inconvenience to be cleaned on account of their angles. In addition to family houses, some places requiring the special sanitary management, such as pharmaceutical companies, food factories, restaurants and the like, have tried to maintain corners of the building hygienically and spent much time, money and man power for the sanitariness . However, the corners are not clean enough practically and not managed efficiently, compared with the expenses.

On the other hand, some structures have also internal corners to be treated hygienically besides the corners of buildings illustrated above. Concretely, the structure, such as wall closet, drawer and so on, also needs to prevent the contamination of corners on the interior side by dust, pollutant or insects.

Presently, the method for decorating a corner has disclosed that a construction material such as molding was attached onto the corner (Korean Laid-open Patent No. 96-4686; Japanese Laid-open Utility Model No. Sho. 49-118715) . However, the above method does not consider a sanitary problem even if it creates beauty apparently and thus only become an extended interior work. In addition, this construction material can make an angle again in between a molding and a wall and may include decorations by itself. Therefore, alien substance such as dust can adhere onto this angles and decorations easily and possibly provides habitats for various kinds of microorganism, insects or the like. In order to solve this problem, corners have been treated with rounding before buildings are constructed or after they are completed. Besides, the special cleaner has been suggested to make the angular corner site clean immaculately. However, these trials have not been exploited widely since the rounding process is not easy and the use of cleaner cannot settle the problem fundamentally.

In the meantime, the construction material with a triangular projection has been illustrated to close the crevice of the corner at the apex of wall (Japanese Laid-open Utility Model No. Sho. 48-28625 and Sho. 48- 8923) . Unfortunately, it was a simple device to fill up the corner space and did not regard as to the hygienic disadvantage for controlling microorganisms or insects. Furthermore, most of construction material existed previously was composed of inelastic substance such as hardened plastic, styrofoam, wood and the like. Thus, if the corner did not have exact 90°, the above material was inconvenient to apply for the interior side of the building.

Therefore, the inventors of the present invention have tried to αevelop novel structure for rounding a corner in order to close the inner corner of building conveniently even if in various forms. In addition to the physical improvement, the structure of present invention has given more economical benefits. Concretely, it can be - manufactured to prevent notorious bacteria, insects and so on from the inhabitation, to remove offensive ordors, to emit proper fragrance and to facilitate the cleaning of corners .

DISCLOSURE OF INVENTION

The object of the present invention is to provide a structure for rounding a corner of the structural body physically.

Another object of the present invention is to provide a structure for rounding a corner physically which has an anti-bacterial activity.

Another object of the present invention is to provide a structure for rounding a corner physically which has an insecticidal activity.

The other object of the present invention is to provide a structure for rcunding a corner physically which can remove malordor and/or emit fragrance.

In order to accomplish the objects, the present invention provides- a structure which sticks to, attaches to and/or is fixed onto corners so as to close the empty space of the corners appearing in the interior sides of building onto contact regions formed in between a wall and a wall and between one or two walls and a ceiling or a floor. Particularly, the present invention provides a structure for rounding a corner made of elastic material.

Generally, the corners in the interior of constructure like a building is formed in the contact regions that a wall, a ceiling and a floor meet at an angle of about 90^° respectively. The structure of the present invention has a shape identical to the resulting space. That is to say, the structure mentioned above fulfills the function of closing the empty space formed in the corners. Concretely, the structural body attaches, adheres and is fixed onto the empty space (hereinafter referred to as " apex corner ") which is formed when three faces (for example, two walls and a ceiling or a floor) meet at an angle of about 90° respectively. In addition, the structural body attaches, adheres and is fixed onto the space (hereinafter referred to as " linear corner ") when two faces (for example, a wall and a wall, two faces among a wall and a ceiling or a floor) are adjoined. In this case, the structures for rounding corners have different kinds of forms respectively since the apex corner and the linear corner make disparable spatial shapes.

Hearinafter, the shapes of the structure in the present invention will be illustrated in detail.

(1) The shape of the structure for rounding an apex corner formed by three faces

In the present invention, one of the structures has a shape which can be applied to close the empty space formed at the contact point of three faces (for example, a wall-a wall-a ceiling or a wall-a wall-a floor) (See FIG. 1) .

The structural body mentioned above has the shape of a triangular pyramid (tetrahedron) , which is similar to the region obtained by cutting the corner of a hexahedron. At that time, each angle made by adjacent three faces forming the apex of the horn corresponding to the end of the corner is about 90° .

The corner does not always make an angle of a constant value, depending upon the features of the constructure since the corner of building is not usually completed at an exact angle. This situation should be considered. Concretely, the angle of the corner formed in between three faces of vertex can be changed properly at the range of 85 ~ 95° . On the other hand, the angle formed from two walls can be more or less than 90° , depending on the shape of land and the peculiarity of building. Therefore, in the present invention the angle formed in between the previous three faces is not limited to a specific value. Hence, the structural body of the present invention is required to consist of elastic material essentially in order to be applied to various kinds of corners with different angles and morphologies in practice.

Besides, the corner may not be completed at an exact angle in accordance with the feature of the structure since the end of the corner is rarely found to be finished at an exact angle in conventional cases. Preferably, the apex of the structural body in the present invention should be cut off partly. Namely, the triangular pyramid of which the top has been cut off is an ideal shape when considered in the conceptual basis.

Meanwhile, in the case that the structural body mentioned above makes a precise tetrahedron, the face opposite to the apex of the tetrahedron (hereinafter referred to as " opposite face ") and the face of the structure (for example, a wall and a ceiling or a floor) are adjoined at a proper angle and thus another " corner " can also appear. In order to escape this situation, preferably the opposite face should head for the apex, that is, forms a smooth concave internally curved.

(2) The shape of the structure for rounding a corner space formed by two faces

In the present invention, one of the structures has a shape which can be applied to close the empty space formed at the contact point of two faces (linear corner) , for example, a wall and a wall, a wall and a ceiling or a floor. (See FIG. 3)

In this case, the structural body has a similar shape to a triangular prism and its longitudinal section is shaped in a triangle, a trapezoid and the like basically.

Generally, the angle between two faces

(hereinafter referred as to " face angle " ) which are made in the contact region of the side formed by the two faces in between a wall and a wall, a wall and a ceiling or a wall and a floor has an angle of about 90° in the structural body of the present invention. However, the corner of the structure like a building happens to be completed at an exact angle and the face angle mentioned above can be changed properly at the range of 85 ~ 95° , providing against contingencies. On the other hand, the face angle can be more or less than 90° depending on the shape of land and the peculiarity of building. Therefore, in the present invention the face angle is certainly not limited to a specific value. In addition, the structural body of the present invention is required to consist of elastic material essentially in order to be applied to various kinds of corners with different angles and morphologies practically.

Besides, the corner happens to be finished not at an exact angle, depending upon the feature of the structure since the end of the corner is rarely found to be finished at an exact angle in conventional cases. Preferably, the structural body of the present invention mentioned above forms the shape of which the base side is cut off partly. That is to say, if considered in the conceptual basis, the shape should be a trapezoid which can be made when the apex of a triangle opposite to the base side is cut off toward the longitudinal section of the structural body.

Meanwhile, in the case that the longitudinal section of the structural body mentioned above has the precise shape of triangle, trapezoid and the like, another " corner effect " can appear since the face towards the base side mentioned above (hereinafter referred as to " opposite face ") and a wall, a ceiling or a floor are adjoined at a designated angle. In order to escape this situation, the opposite face mentioned above is required to head for the base side, that is, forms a smooth concave internally curved.

In the structural body prepared in (1) and (2) process illustrated above, the apex, the base side and the end of other sides are possible to be separated when they are elaborate and thin. Thus, the structure of the present invention is difficult to be manufactured and furthermore inconvenient to be constructed, maintained and repaired. Hence, the corner or the side in the previous structural body, which is not touched with the apex mentioned above, can be treated properly by chamfering or rounding.

In addition, the structure of the present invention can be made of any material, if the material is processed and mold easily, keeps the original shape after manufactured and is conserved stably not to be decomposed naturally or by germs, insects and the like. Preferably, the structural body can be constructed by using elastic material in order to be attached flexibly onto the corner of building not finished at an exact angle .
