Description

Surface material for elevator doors{An Elevator Door Protector}

The present invention relates to a reinforcing material that protects the elevator door surface, and more specifically, attaches a rubber magnet that is easy to attach and detach to a design surface (also called a door surface or a design surface) of an elevator door made of metal. By forming a glossy coating on one or both sides of the rubber magnet and providing a tape to support the rubber magnet on the elevator rim, the design surface of the door is prevented from being contaminated or damaged by external impact or physical force. It relates to an elevator door surface retaining material that can protect the original intact.

In general, the decorative panel products used (applied) for elevator doors and cages are coated with decorative patterns by various methods such as painting and printing on the surface of steel materials.

Elevators are largely divided into cages and doors inside, and elevator design materials are used for cages and doors by processing metal materials such as stainless steel or galvanized steel. Recently, a variety of decorative patterns are coated and printed on the surface of the design material for the purpose of doubling the design effect of the design material and improving the boarding environment.

From the manufacture of the elevator to the use of the elevator, the elevator goes through processes such as "bending processing of metal materials-design of the surface of the material-attachment of the protective film on the surface of the design-assembly of the accessories-on-site installation-attachment of the surface of the design-removal of the material after completion of the move-in".

The elevator door is installed on the site before the construction work is completed, and a lot of opening and closing operations (use) are performed until the occupant completes the occupancy until completion of construction and construction. For this reason, the protective film and aphrodisiac material used in elevator doors are excellent in adhesion, so they should not fall during use, and the thickness is so thin that they should not get caught in or interfere with the door frame when the door is opened and closed.

Therefore, these products have a plastic resin protective film coated with adhesive for the purpose of protecting the surface of the design from contamination, scratches, etc. that occur during subsequent processes such as assembly, transportation, and installation until the product is installed in the building after the coating is completed. ).

In addition, after the elevator door is installed in the building, it is possible to protect the surface of the door under various elevator usage conditions until the completion of the construction of buildings, moving, etc., and the occupancy of the residents on the door surface where the protective film is attached. For the purpose, it is used by additionally sticking a thickening pad (secondary) that has a better retention effect than a protective film.

Subsequently, when the occupancy is finally completed, the primary protective film and the secondary auxiliaries are removed from the door design (table) surface and used. Therefore, the protective film and the reinforcing material are used as consumable products that temporarily protect the design surface of the door.

In more detail, the primary protective film is PE coated with an adhesive of an organic solvent in a thickness of several tens of microns for the purpose of protecting from relatively light external impacts during subsequent assembly, transportation, and field installation processes after the surface treatment process of the design material is completed. Films of (POLYETHYLENE), PET (POLYETHYLENE TEREPHTHALATE), and PVC (POLYVINYL ALCOHOL) are used.

In addition, after the on-site installation of the elevator door is completed, an adhesive is applied to the door surface with the primary protective film attached for the purpose of protecting the design surface for a long period of time from severe external impacts that may occur during various construction work processes until the occupancy is completed. Plastic protective pads, such as foamed PE and PVC, with a thickness of 0.1 to 2.0 mm are attached as a secondary and used as a reinforcing material.

However, these conventional primary protective films and secondary auxiliaries are adhered to the surface of the design material by a strong adhesive, making it difficult to remove the protection material after completion of occupancy. There is a discomfort that needs to be cleaned, and a serious problem in which the design surface is damaged by the removal of the adhesive using a strong organic solvent frequently occurs.

In addition, the primary and secondary auxiliaries cannot be reused. As a result, the use of auxiliaries produces large amounts of environmentally hazardous waste, and the cost of installing auxiliaries by manufacturers is very high, causing a cost increase.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described to be easily carried out by those of ordinary skill in the art.

Elevator door surface reinforcing material 100 according to the present invention, as shown in Figures 1 to 5,

In the elevator 110 is installed in an apartment or high-rise buildings, etc. to lift and move with people or cargo,

The elevator 110 is installed in the cage 111 for loading a person or cargo therein, and is installed in the cage 111 to allow access to the inside of the cage 111. And a door 112 made of an outer opening and closing part 112b that is opened and closed simultaneously with the inner opening and closing part 112a while being fixedly installed on each floor of the building,

On the exposed surface of the door 112 (hereinafter referred to as a design surface or design surface), a rubber magnet 120 that prevents damage to the design surface by external impact or physical force is in surface contact with the door 112 by magnetic force. Attached,

Indentations of the rubber magnets 120 on the inner surface of the rubber magnets 120 attached to the doors 112 or on both sides of the inner and outer surfaces of the door 112 due to external impact or physical force are applied. It is equipped with a glossy coating unit 130 UV-treated to prevent formation.

Here, the design surface refers to an exposed surface, not the entire surface of the door 112, and enters the cage 111 or a sleeper (a three-dimensional frame, not shown) and the upper surface of the door to which exposure is excluded. , Part of the side, the bottom surface is excluded. More specifically, the inner opening and closing portion 112a is covered by the cage 111, and the outer opening and closing portion 112b is partially covered by sleep.

In general, the elevator should protect the design of the elevator door for a period of time from severe external shocks or arbitrary physical forces that may occur during various construction work processes until installation is completed after the installation is completed at the construction site of an apartment or high-rise building.

Therefore, conventionally, for the purpose of protecting the design surface of an elevator door for a long period of time, a protective film is first attached to the design surface (door surface) to protect it, and plastics such as foamed PE, PVC, etc. with a thickness of 0.1 to 2.0 mm coated with an adhesive on it It is used by attaching a pad and supplementing it secondaryly.

However, these conventional primary protective films and secondary auxiliaries are adhered to the surface of the design material by a strong adhesive, making it difficult to remove the protection material after completion of occupancy. There is a discomfort that needs to be cleaned, and a serious problem in which the design surface is damaged by the removal of the adhesive using a strong organic solvent frequently occurs.

In order to solve this conventional problem, the present invention attaches a thin plate-shaped rubber magnet 120 having a collective magnetism to the entire design surface of the elevator door 112, thereby providing an external shock or physical force through a cushioning force that is a characteristic of rubber. To protect the design surface from damage caused by the magnetic force to be easily attached to the elevator door 112 to increase the convenience of use.

The elevator door 112 is made of a metal material, and the rubber magnet 120 is easily surface-coupled.

In general, a rubber magnet is a magnet formed by mixing ferrite (iron oxide) powder with a soft rubber (chlorinated polyethylene) material, which is mainly formed into a plate, which is easy to deform and easy to process.

These rubber magnets are widely used because they are processed with educational characters and promotional stickers on the surface of iron household items such as blackboards and refrigerators.

A rubber magnet plate with a thickness of 0.3 to 1.0 mm is mainly used for sticker use.

Rubber magnets are classified into isotropic magnets with general magnetic force and anisotropic magnets with strong magnetic force. Anisotropic magnets show magnetic force 2 to 3 times stronger than that of isotropic magnets.

The rubber magnet of the present invention can be used both isotropic magnets or anisotropic magnets.

In addition, the rubber magnet 120 used in the present invention is a thin film, and it is coated with a glossy liquid coating on the surface of a general rubber magnet plate, and it is possible to apply dry glossy coating products mainly using an ultraviolet (UV) curing device. To make. This is to give the following characteristics to the surface of the elevator design.

Recently, decorative products such as elevator doors are mainly used for decorative products that have improved design performance by applying a variety of surface treatment (painting, printing, laminating) technologies, and the surface condition of these decorative products is also glossy (glazed, matte). Products with various surfaces ranging from roughness (solid, texture, embossing) are produced.

Among these surfaces, products with high gloss and high surface roughness are easily damaged by external impacts. When using a general rubber magnet without a glossy coating on the surface to protect the door surface of elevator products, the pressure of external impacts When the pressure of the rubber magnet is transmitted to the product design surface, a defect in which a black indentation of the rubber magnet surface is formed on the product design surface may frequently occur.

In order to prevent this, the rubber magnet 112 of the present invention is coated with a high-gloss liquid coating on the surfaces of both sides or inner wall surfaces of the rubber magnet to a thickness of several tens of microns, and then formed with a UV-coated glazed coating 130 to form a rubber. The high-gloss coated surface of the magnet can prevent the black indentation from transferring to the design surface of the product (elevator door) during external impact.

The heat resistance temperature of the rubber magnet is around 100℃, so when curing at high temperature after painting the liquid coating, the coating is cured using a UV curing device with a low curing temperature and a fast curing time to prevent dimensional deformation.

The elevator 110 door 112 of the present invention is installed in the cage 111 to allow access to the inside of the cage 111, the inside opening and closing part 112a opened and closed, and fixedly installed on each floor of the building While being composed of the outer opening and closing portion 112b that is opened and closed simultaneously with the inner opening and closing portion 112a, the rubber magnet 120 is the design of the inner opening and closing portion 112a and the outer opening and closing portion 112b of the door 112. It is applied to all surfaces.

Therefore, the inner surface of the inner opening/closing portion 112a and the outer surface of the outer opening/closing portion 112b are exposed to the outside, and the exposed surface of the door exposed inside the cage 111 and the outer surface of the cage 111 are exposed. There is an exposed surface of the door.

In addition, a tape 140 is further provided on the rim of the rubber magnet 120 so that the rubber magnet 120 is not attached to the door 112 and is not randomly dropped by external force. That is, the tape 140 to which the outer surface of the rubber magnet 120 and the non-exposed surface of the door 112 are adhered is provided. The rubber magnet according to the present invention is coupled by magnetic force with the exposed surface 112-1 of the door 112, and the outer border of the rubber magnet and the door 112 are attached together so as not to be moved or dropped by external force. . At this time, since the exposed surface of the door (or exposed surface, 112-1) is covered by a rubber magnet, the tape 140 is attached to the non-exposed surface 112-2 of the door as shown in FIG. In addition, when the door is closed, the tape 140 is attached to the contact surfaces 112-3 which are in contact with the doors, and the attachment width is smaller than that of the non-exposed surfaces 112-2.

The door 112 is mostly made of a wide flat surface exposed, a side bent at the front, and a back bent at the side, and the double front is extended from the exposed surface 112-1 and the exposed surface. It is formed and is made of a non-exposed surface 112-2 inserted into the cage or inside the sleep even when the door is closed. At this time, the rubber magnet 120 is continuously and continuously attached to the exposed surface 112-1 of the front surface, and is not attached to the non-exposed surface 112-2.

In addition, the rubber magnets 120 are spaced apart by a predetermined width along the contact surfaces 112-3 that come into contact with each other when the doors are closed among the exposed surfaces 112-1 depending on the attachment environment.

Therefore, the rubber magnet 120 is continuously and continuously attached based on the front surface of the door, even when closed, the separation surface of the non-exposed surface 112-2 inserted into the cage or the inside of the sleep is spaced apart from the contact surface 112-3. It is not attached more widely than the cotton. That is, in the rubber magnet, a spaced surface that is not attached to the contact surface 112-3 based on the front surface of the door is formed narrower than the non-exposed surface 112-2.

In addition, the tape 140 is attached to the front of the door with a wider width than the contact surface 112-3 where the non-exposed surface 112-2 inserted into the cage or sleep inside upon closing is exposed when closed. When the rubber magnet 120 is continuously attached to the contact surface 112-3, the tape 140 is not attached to the front side of the door, but is attached only to the side.

The tape 140 may prevent the corner portion of the rubber magnet 120 from easily falling off the door, and at the same time, prevent the scratch of the corner portion of the rubber magnet 120 to further increase recyclability.

And the range of retaining the rubber magnet 120 on the design surface of the elevator door 112 is when the elevator door is opened and closed, leaving (approximately) about 5mm extra on the vertical surface of the door that comes into contact with each other, and restraining (attaching) the elevator. It is desirable to keep the direction only up to the vertical surface where the door protrudes to the outside. 3, the rubber magnet 120 is attached only to the exposed surface of the door 112 in the sectional view, and is excluded from a part of the edge. The excluded part enters the cage or sleep inside and is not exposed to the outside. . Accordingly, the rubber magnets 120 are different from each other on the side of the elevator door 120, and the areas of the excluded surfaces are different from each other.

When the rubber magnet 120 is attached to the door 112 with the area as described above, after the elevator door is installed, the design surface of the door protruding to the outside can be minimized, and at the same time, the occupancy of the door is completed and the occupancy is completed (rubber magnet) ) Can be easily removed, improving work convenience.

In addition, the present invention is a thin plate-shaped steel plate plate attached by the magnetic force of the rubber magnet 120 without the use of an adhesive so as to more securely protect the design surface of the door during a severe external impact on the outer surface of the rubber magnet 120 ( 150).

Thus, by providing the steel plate 150 on the outer surface of the rubber magnet 120, the strong external impact is preferentially relieved by the steel plate 150, the door by the rubber magnet 120 The design surface protection of 112 can be made more stable.

The rubber magnet 120 of the present invention can be attached to the surface of the cage 111 of the elevator as well as the door.

In addition, when the rubber magnet 120 is attached to the door, it may be attached to the entire door as a single sheet, or may be divided into several sheets to be installed.

As described above, the elevator door surface reinforcing material 100 of the present invention attaches a rubber magnet to the door surface so that the door of the elevator 110 can be prevented from being damaged by external force, and the inner surface of the rubber magnet (on the door The surface of the door can be safely maintained and protected by preventing the indentation of the rubber magnet due to external force from being formed on the design surface by placing a glossy coating on both sides or on both sides).

As described above, the elevator door surface reinforcing material according to the present invention is provided with an easy-to-detachable rubber magnet on the design surface of an elevator door made of metal and forms a glossy coating on one or both sides of the rubber magnet to form a rubber magnet on the elevator rim. By providing the supporting tape, it is possible to protect the design surface of the door, such as the door, by preventing the design (table) surface of the elevator door from being contaminated or damaged by external impact or physical force.
