Description

  The present invention relates to a door device having a sliding door that is preferably used as a so-called wall panel or the like.

  2. Description of the Related Art Conventionally, as this type of door device, there is known a door device in which a door having a door wheel is slidably supported on rails arranged above and below (see, for example, Patent Document 1). As such a door device, various types of rail devices have been developed that include a rail base that is attached to a floor, a ceiling, or the like, and a rail body that is provided on the rail base and supports the door wheel of the door. In an apparatus that is required to have at least a good appearance from the front side of the door, a decorative surface is often formed on the wall of the rail base.

  Further, in such a door device, when it is required to improve the sound insulation performance in the closed state or to improve the external appearance, the door device is extended so as to conceal part of the decorative surface of the rail base. An extending edge portion may be provided.

  However, in such a configuration, in order to pursue high sealing performance, it is necessary to make the clearance between the decorative surface of the rail base and the inner surface of the extended edge of the door as small as possible. For this reason, with such a specification, when the door is slid, the inner surface of the extended edge portion may be rubbed against the decorative surface of the rail base, and the coating of the decorative surface is peeled off and the scratches are easily left. . Such scratches are visible from the front side of the door when the door is opened, and there is a risk that the value of the product will be significantly reduced. If such a flaw is found during delivery inspection, it may be necessary to repair the product before delivery. Therefore, some countermeasure is desired.

  For such a problem, it is not conceivable to take countermeasures such as configuring the entire inner surface of the extended edge of the door with a soft material, but there are various types such as a bottom joint cover on the extended edge of the door. It may be necessary to attach the constituent members. In such a case, there is a problem in that it is not easy to configure so as to be protected by a material that hardly scratches the entire inner surface of the extended edge without causing a complicated structure and an increase in the number of parts. was there.

Japanese Patent No. 3459843

  The present invention has been made paying attention to such a situation, and an object thereof is to solve the above-described conventional problems without causing a complicated structure and an increase in the number of parts.

  The present invention takes the following means in order to solve the above-described problems.

  That is, the door device according to the present invention is configured such that a door having a door is slidably supported on rails arranged on the upper and lower sides, and at least one of the rails is visible from the front side of the door. A rail base having a decorative surface formed on a wall, and a rail main body provided on the rail base and supporting the door roller of the door by rolling contact, and the door of the decorative surface of the rail base are provided. The rail body is provided with an extended edge portion that extends so as to hide a part thereof, and is interposed between the decorative surface of the rail base and the extended edge portion of the door. In addition, a protective piece that is less susceptible to scratches than the decorative surface is integrally provided.

  Here, the door cart is not limited to the one that receives gravity acting on the door, but includes one provided to prevent the door from falling down.

  In addition, the phrase “less susceptible to scratches than a decorative surface” means that the surface of the protective piece has a characteristic that the surface of the protective piece is less likely to be scratched than the decorative surface, or even if the surface is scratched. Means that it is inconspicuous. Various characteristics such as a higher hardness than the decorative surface or a slippery surface can be considered as the characteristics that are difficult to scratch. On the other hand, those that are not noticeable even if they are scratched may be those whose surface has a pattern or processing similar to that of the scratch, and specifically, a hairline pattern is applied to the surface by printing or machining. Can be mentioned.

  In particular, the protective piece preferably has an uncoated surface, but may be coated with a scratch-resistant coating.

  With such a configuration, even if the clearance formed between the rail and the extended edge of the door is set to a very small value, the conventional problem does not occur. That is, even when the inner surface of the extended edge portion is displaced toward the rail when the door is slid, the extended edge portion rubs against the protective piece, not the decorative surface of the rail base. For this reason, it is possible to solve the problem that scratches remain on the decorative surface. Further, as described above, since the surface of the protective piece is less susceptible to scratches than the decorative surface, the conventional problem that the appearance is impaired when the door is opened can be solved. it can. In addition, since the protective piece is provided integrally with the rail body, the structure is not complicated and the number of parts is not increased.

  As a suitable aspect of the rail base, one made of a color steel plate having a coating film for forming the decorative surface can be mentioned.

  The rail body is preferably an integral product made by bending a stainless steel plate including the protective piece, or an integral product made by extruding an aluminum alloy including the protective piece. .

  As a specific embodiment, there may be mentioned one in which the upper rail is attached to the ceiling and the lower rail is attached to the floor.

  The concealing process by the extended edge of the door may be performed on either the upper or lower rail, but when the appearance is important, it is preferable to perform the process on at least the lower rail. In this case, the protective piece is provided on the rail body of the lower rail.

  In particular, if a bottom joint cover for forming a joint bottom is provided when emphasizing the appearance of the joint formed at the butt portion of the doors, the extended edge of the door has a lower end of the bottom joint cover. Will be included.

  In addition, when high sound insulation performance is required, the extended edge portion covers a part of the rail through a particularly narrow sound-insulating minute clearance.

  Since the present invention is configured as described above, when the door is slid, the inner surface of the extended edge portion is rubbed against the decorative surface of the rail base, the decorative surface paint is peeled off, and the scratch remains. The problem can be solved without causing a complicated structure and an increase in the number of parts.

Since the structure of the door frame 51, the front panel 52, and the back panel 53 conforms to the slide inspection door 4, the description thereof is omitted.

  Next, the operation of the door device 1 will be described.

  As shown by a solid line in FIG. 2, the door device 1 according to the present embodiment has the front space in the state where both the hinged door inspection doors 5 are held at the closed position flush with the three slide inspection doors 4. 71 and the back space 72 are completely partitioned. That is, in this state, since there are only minute clearances C3 and C4 between the ceiling rail 2 or the floor rail 3 and the doors 4 and 5, they are generated from various facilities arranged in the back space 72. It is possible to suppress noise from leaking into the surface space 71.

  What is necessary is just to open at least one of the said hinged door inspection door 5 when checking the said various facilities. That is, when only one of the hinged door inspection doors 5 is opened, the slide inspection door 4 can be moved by the door width of one piece of the hinged door inspection door 5, and the door width is one sheet at a desired position. Can be formed. Further, when both of the hinged door inspection doors 5 are opened, the slide inspection door 4 can be moved by the width of the two hinged door inspection doors 5 and can be moved to a desired position for two door widths. An opening can be formed.

  In this way, when the inspection or the like is performed, the slide inspection door 4 can be slid along the ceiling rail 2 and the floor rail 3, but at that time, the extended edge of the slide inspection door 4 is extended. The problem that the part 472 scratches the decorative surface 371 of the floor rail 3 does not occur. That is, the inner surface of the extended edge 472 is formed by the sound insulating rubber R4 and the bottom joint cover 45, which are preferentially slid onto the protective piece 323 provided on the rail body 32 of the floor rail 3. By touching, the decorative surface 371 is not touched. Therefore, it is possible to prevent scratches from remaining on the decorative surface 371. Since the surface of the protective piece 323 has no coating and has a hairline pattern 323a, it does not stand out even if it is slightly scratched.

  When the slide inspection door 4 is assembled between the ceiling rail 2 and the floor rail 3, the slide inspection door 4 is moved between the rails 2 and 3 with the guide roller 48 removed. Installing. After that, when the screw B7 is attached to the back space 72 side of the slide inspection door 4, between the sound insulation rubber R3 and the ceiling rail 2, and between the sound insulation rubber R1 and the slide inspection door 4. A sound insulation seal is formed in each case. More specifically, a minute clearance C3 is formed between the front-side sound insulation rubber R3 and the ceiling rail 2, and the sound-insulation rubber R1 is between the back-side sound insulation rubber R1 and the slide inspection door 4 and the slide inspection is performed. It will lightly contact the back panel 44 of the door 4. Here, when the fine clearance C3 is to be adjusted, the contact of the seal portion is adjusted by inserting the liner L between the roller base 481 of the guide roller 48 and the back panel 44. . In this case, a plurality of liners L having a certain thickness may be prepared and the hit adjustment may be performed using the required number, or a plurality of types of liners L having different thicknesses may be prepared and used. The hit adjustment may be performed selectively. Since these liners L have a structure with a notch L1 on one side, they can be inserted / removed between the roller base 481 and the back panel 44 only by loosening the screw B7.

  By performing the hitting adjustment in this way, the fine clearance C3 for sound insulation becomes appropriate, and good sound insulation performance is exhibited. More specifically, in the case of this embodiment, the fine clearance on the front space 71 side is set to an appropriate value by the contact adjustment by the liner L, while the contact pressure of the sound insulating rubber R1 on the back space 72 side is set appropriately. It becomes possible to set to any value.

  Since the door device 1 according to the present embodiment is configured as described above, the inner surface of the extended edge portion 472 is rubbed against the decorative surface 371 of the rail base 31 when the slide inspection door 4 is slid. The conventional problem that the surface 371 is peeled off and scratches remain can be solved without causing a complicated structure or an increase in the number of parts.

  In particular, since the ceiling rail 2 is attached to the ceiling 91 and the floor rail 3 is attached to the floor 92, respectively, with all the slide inspection doors 4 and the hinged door inspection doors 5 being closed flush, It functions as a wall surface panel for partitioning the front space 71 and the back space 72.

  Moreover, since the concealing process by the extended edge part 472 of the said slide inspection door 4 is performed to the rail main body 32 of the said floor rail 3, an external appearance can be made preferable.

  Further, the joint 46 is provided with a bottom joint cover 45 for forming a joint bottom, and an extension edge portion 472 of the slide inspection door 4 is provided for concealing the rail body 32 of the floor rail 3. Since the lower end portion 452 of the bottom joint cover 45 is included, these extended edge portions 472 are preferentially brought into sliding contact with the protective pieces 323 provided on the rail body 32 of the floor rail 3, thereby making the decorative surface 371. There is no touch. Therefore, it is possible to prevent a scratch from remaining on the decorative surface 371.

  Further, the extended edge portion 472 covers a part of the floor rail 3 through a particularly narrow sound-insulating micro-clearance C4. Therefore, the extended edge portion 472 is generated from various facilities disposed in the back space 72. It is possible to suppress noise from leaking into the surface space 71.

  The present invention is not limited to the embodiment described above.

  The upper end portion of the bottom joint cover according to this embodiment is made to coincide with the upper end of the upper frame of the door frame, but is extended to a position where it matches the upper end of the front panel, and the upper end of the bottom joint cover The upper extending edge portion may be formed mainly with the upper portion, the upper end portion of the panel body, and the front bent portion of the upper frame. In this case, a protective piece may be provided on the ceiling rail so that the decorative surface provided on the ceiling rail is not scratched.

  Further, the rail body may be an integrated product made by extruding an aluminum alloy including a protective piece.

  Further, the slide inspection door and the hinged door inspection door may be provided with a locking mechanism using a round drop or a lock handle at an arbitrary place.

  In addition, the ceiling rail is not limited to the one that can be directly attached to the ceiling, but may be one that is attached to the ceiling via an upper plate material. Similarly, the floor rail is not limited to one that is directly attached to the floor. It may be attached via a lower plate material between the floor and the floor.
