Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to the structure of sliding doors such as windows and doors in buildings and doors in furniture.

[0002]

[Prior art]

 For example, the windows of buildings in cold regions are double-glazed and have a highly airtight structure. By the way, the window is detachable from the door frame in preparation for cleaning or repair replacement.If the sliding door can be lifted off the door frame, the window between the sliding door and the upper rail section There is a defect that the airtightness is impaired because the gap of the play allowance acts as a flow passage for air. This problem of airtightness is also related to heat insulation, and ventilation is performed by the flow of air. Therefore, especially in cold regions, the heat loss of heating is large, and resource energy is consumed more than necessary.

[0003]

[Problems to be solved by the invention]

 The problem to be solved is, first, the structure of a sliding door which is highly airtight while being capable of being opened and closed and detachable from the door frame for cleaning and repair replacement. Another object is to provide a sliding door structure in which the sliding door is a sliding type.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a sliding door in which a sliding door is guided by a groove-shaped upper rail portion and a lower rail portion of a door frame so that the sliding door can be opened and closed and lifted up and removed from the door frame. In the structure, an inner rail body including an upper sponge-like elastic member and a lower rail member is provided along the upper rail portion, and the sliding door is guided to the upper rail portion via the inner rail body. Features. Further, in the present invention, the upper rail portion, the lower rail portion, and the sliding door are sliding doors, and the sponge-like elastic member is a pair of parallel inner and outer members, and the rail member is located at the center of the lower surface of the member. It has inner and outer parallel inner rail surfaces and outer rail surfaces formed with a hanging partition as a boundary, and the inner and outer rail surfaces guide inner and outer sliding doors.

[0005] The inner rail body in the present invention may be either integrally mounted on the upper rail portion or removably mounted on the upper rail portion. In this configuration, the sponge-like elastic member is integrally disposed on the groove surface of the upper rail section by gluing or the like, so that the inner rail body does not fall off the upper rail section even when the sliding door is removed. The sponge-like elastic member is made of spongy rubber or synthetic resin, and its elastic force is to force the rail member into contact with the sliding door to maintain airtightness between the upper rail portion and the sliding door, while maintaining the airtightness between the sliding door and the sliding door. The sliding door does not hinder the lifting work, and the sliding door can be smoothly opened and closed with respect to the rail members.

[0006]

[Embodiment of the invention]

 FIGS. 1 to 3 show a sliding door structure as an embodiment of the sliding door structure according to the present invention, in which a sliding door is a sliding door, and a door frame 1 mounted on a frame has a downwardly grooved upper rail. The upper and lower rails 2, 3 are provided between the upper and lower rails 2, 3 so as to be openable and closable. The upper rail portion 2 has a groove width slightly larger than the combined width of the inner and outer sliding doors 4 and 5 and the total width of the partition portion 9 described later. An inner rail body 6 is arranged from the other end to the other end. The inner rail body 6 includes an upper sponge-like elastic member 7 and a lower rail member 8, and the sponge-like elastic member 7 is a pair of inward and outward parallel members. An inner / outer parallel inner rail surface 10 and an outer rail surface 11 are formed with the hanging partition 9 as a boundary, and the inner rail surface 10 and the outer rail surface 11 form upper and lower sliding doors 4 and 5, respectively. The doors are guided so that they can be opened and closed, and the upper edges of the sliding doors 4 and 5 are airtight. Further, the inner rail body 6 is provided integrally with the inner and outer sponge-like elastic members 7 glued to the groove surface of the upper rail portion 2.

The lower rail 3 guides the lower edges of the inner and outer sliding doors 4, 5 so that they can be opened and closed by parallel grooves inside and outside. The lower rail portion 3 has a rail surface reinforced with a thin aluminum base piece 12 so that the sliding doors 13 in the sliding doors 4 and 5 can run on the base piece 12 respectively.

The inner and outer sliding doors 4, 5 are provided with a raised portion 14 on the lower surface except for the location of the door roller 13, and the raised portion 14 rubs the base piece 12, thereby sliding the sliding doors 4, 5. Some airtightness is also provided at the lower edge. A belt-shaped packing 15 is formed on the outer left side edge of the inner sliding door 4, and an inwardly inclined slope portion 16 is formed on the inner right side edge of the outer sliding door 5. When the belts 4 and 5 are closed, the band-shaped packing 15 comes into contact with the slope 16 so that airtightness can be obtained even between the inner and outer sliding doors 4 and 5.

Further, a band-shaped packing 17 is provided on each of the right inner side surface portion 1a of the door frame 1 with which the inner sliding door 4 right side abuts and the left inner side surface portion 1b of the door frame 1 with which the outer sliding door 5 left side abuts. When the inner and outer sliding doors 4 and 5 are closed, they come into contact with the band-shaped packing 15 so that airtightness can be obtained between the inner and outer sliding doors 4 and 5 and the door frame 1. In this way, good airtightness is required for the entire sliding doors 4 inside and outside the door frame 1.

In the above-described embodiment, the type of the sliding door has been exemplified. However, the present invention is not limited to this. For example, as shown in FIG. 4, the outer sliding door 5 in FIG. By using the window 18, a structure including a single sliding door 4 can be provided.

[0011]

[Effects of the invention] A. According to the first aspect, airtightness can be obtained at the same time while being able to be opened and closed and detachable from the door frame for cleaning and repair / replacement. Moreover, it can be manufactured structurally at low cost and has a great economic effect. B. According to the first aspect, the airtightness and the economical effect can be simultaneously obtained even if the sliding door is of the sliding type.
