Description

The present invention relates to a sliding door rail and floor joints attached to the floor surface, joints between floor members and members constituting doors, windows, etc., partings provided to cover these joints and steps, etc. This relates to floor accessories such as wood.
About.

  2. Description of the Related Art Conventionally, a sliding door rail having a concave rail groove on which a door wheel installed on a lower surface of a sliding door travels is directly fixed to a floor surface. Unlike the sill type in which a groove is formed on the floor surface, the sliding door rail of the type that directly adheres to the floor surface is easy to construct because it does not require floor surface processing.

  By the way, in such a type of door roller rail that directly adheres to the floor surface, the rail protrudes from the floor surface, so that the height is limited and the entire surface is formed flat, and the level difference from the floor surface is reduced to increase the age. A structure that does not obstruct traffic, such as the disabled, disabled, and wheelchairs, is required.

  In order to meet the above requirements, conventionally, for example, a stainless steel material such as a stainless steel material that is hard and rust-resistant is known, but the stainless steel material is rigid, but on-site cutting is easy. Rather, it was necessary to check on the situation and dimensions of the installation location in advance and to install what was processed to fit. This complicates the manufacture and management of the product, and in particular, since cutting (cutting) processing cannot be performed on site, it is difficult to deal with adjustments on the spot.

  Therefore, it has been proposed to use a sliding door rail that can be cut on site, for example, by extrusion molding of aluminum. For example, Japanese Patent Laid-Open No. 9-67974 (Patent Document 1 (FIG. 7A)), No. 2002-30853 (Patent Document 2 (FIG. 7b)).

  However, these sliding door rails are inserted through a rail groove or a screw insertion hole formed in a side portion thereof as disclosed in, for example, Japanese Patent Application Laid-Open No. 2001-336342 (see Patent Document 3 (see FIG. 7C)). It was installed and fixed on the floor with a set screw.

  Therefore, there is an aesthetic problem because the set screw used for fixing is exposed on the surface of the rail, and in addition, if the fixed set screw is loosened or lifted, There will be a hindrance to the running of the door cart, and there is a concern that the sole may be damaged in the case of the top surface.

  Furthermore, in the conventional sliding door rail of this type, a rail groove must be installed according to the number of sliding doors to be used. For example, a single sliding door and a plurality of parallel sliding doors are arranged in parallel. Not only the number of rail grooves is different, but the overall width is also different and each is molded separately, and it is necessary to manufacture and store multiple types according to the number of sliding doors used, especially many What is used for this is a parallel arrangement of a plurality of rail grooves, which increases the width, and is not only inconvenient for storage and transportation but also difficult to handle during installation.

  In this regard, a sliding door rail that can be configured on-site to have a required number of rail grooves by appropriately combining a plurality of panel parts set in advance according to the number of sliding doors to be used is disclosed in, for example, Japanese Patent Laid-Open No. 11-200657. These sliding door rails form V-shaped rail grooves by members that are connected adjacent to each other in the width direction. It is not used and the strength of the rail groove is not sufficient. Also, the purpose of use is a sliding door lower rail, and the configuration is not thin, and it is not suitable for an application that is installed directly on the floor.

  Conventionally, floor coverings have been used as long building members to cover the edges of floor surface materials such as floor edges and carpet edges, and to cut edges from other floor materials. For example, utility model registration No. 3066230 ((Patent Document 5 (FIG. 8 (a)), Japanese Patent Laid-Open No. 2004-150111 (Patent Document 6 (FIG. 8 (b) )) Etc.

  However, the floor covering material presented in the above-mentioned conventional patent document 5 has a notch portion in which the upper and lower flanges of the lower rail are fitted on the upper surface of the right side end portion, a protrusion on the lower end of the right side end portion, and a bottom surface. Each of which is formed with a shallow recess for fitting a double-sided tape, is not sufficiently strong because it is fixed with an adhesive tape, and is difficult to reuse after removal. The material is easy to install and can be reused after being removed, but the whole is formed of a hard synthetic resin material as appropriate, and the texture is not beautiful and the strength is not perfect.

JP-A-9-67974 JP 2002-30853 A JP 2001-336342 A Japanese Patent Laid-Open No. 11-200697 Utility Model Registration No. 3066230 JP 2004-150111 A
