Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention includes a slide rail assembly in which an outer rail and an inner rail are engaged via a number of balls, and the outer rail is mounted on a ceiling side. While fixing the inner rail to the sliding door side,
The present invention relates to a suspension structure of a slide rail type overhanging sliding door that slidably suspends a sliding door via a slide rail assembly. 2. Description of the Related Art Among various sliding doors, an upper hanging sliding door is
Since there is no need to install guide members such as sills and rails below the sliding door opening to guide the sliding door, there is no step on the floor surface, and as a sliding door that can sufficiently respond to recent barrier-free requirements, Demand is growing. [0003] Therefore, as an example of a conventional case of suspending this type of an upper sliding door, there is a slide rail type structure as shown in FIG. In this conventional hanging structure of an upper hanging sliding door, a pair of hanging fittings 2 is erected on the upper frame surface 1a of the sliding door 1, while a rail base 4 is erected on the ceiling side of the support frame 3. The channel member 5 is attached to the rail base 4, and the slide rail assembly 6 is fitted in the channel member 5. The slide rail assembly 6 has a large number of balls 6b with respect to the outer rail 6a.
The outer rail 6a is fixed to the channel member 5 while the inner rail 6c is attached to the hanging fitting 2 by slidably engaging the inner rail 6c via the inner rail 6c. The sliding door 1 is slidably suspended via the slide rail assembly 6, and the sliding door 1 slides to open and close the sliding door opening. Reference numeral 7 in the drawing is an openable and closable curtain plate that covers the front side of the suspension structure. [0005] Generally, sliding doors, particularly wooden sliding doors, are not limited to those of a specified size,
There are relatively many cases where it is required to produce ones having greatly different width sizes in accordance with the sizes of various sliding door openings and to assemble them in the sliding door openings. However, in the conventional hanging structure of the upper hanging sliding door, inner rails 6c each having a length dimension capable of obtaining a predetermined sliding distance with respect to the outer rail 6a are individually manufactured in accordance with the width size of the different sliding doors 1, and these inner rails are formed. There has been a problem that various types of slide rail assemblies 6 having the rails 6c must be prepared in advance and used. [0006] Further, in the conventional hanging structure of the upper hanging sliding door,
Since the outer rail 6a and the inner rail 6c are vertically stacked on the upper frame surface 1a of the sliding door 1, and the slide rail assembly 6 is erected, a large installation space is required in the vertical direction. However, there is a problem that the structure is not so good in aesthetic appearance that it needs to be blindfolded by the curtain plate 7 from the front side. [0007] Further, the conventional hanging structure of the upper hanging sliding door is as follows.
A relatively complex mounting configuration with numerous mounting parts,
Therefore, there is also a problem that the work of hanging the sliding door 1 via the hanging metal fitting 2 while lifting the sliding door 1 is troublesome and extremely troublesome. Accordingly, an object of the present invention is to enhance the aesthetics around the sliding door, facilitate the work of hanging the sliding door, and always maintain the same slide rail assembly without changing the inner rail for each sliding door having a different width. It is an object of the present invention to provide a suspension structure of a slide rail type overhanging sliding door which can be used. [0009] Therefore, claim 1
