Abstract

<P>PROBLEM TO BE SOLVED: To dissolve clogging of dust and to eliminate trouble factors when a user and wheels pass, to achieve a barrier-free state by removing projections such as a rail and a flashing at the upper part of a lower frame of fittings to eliminate a groove and step difference to thereby secure a smooth surface. <P>SOLUTION: In this flat frame sash with built-in sash rollers, the projections such as the rail and the flashing at the upper part of the lower frame of a double sliding window, a sliding door or a double sliding door are removed to form the upper part of the lower frame 1 as the smooth surface 2 provided with one or more fine grooves 3, and a plurality of sash rollers are fixedly arranged being built in a hollow part of the lower frame 2 of box-shaped cross section. A lower rail 5 of a sash constituting the fittings is rid of a sash roller and provided instead with a rail-like protrusion 6 at the lower part of the lower rail 5. The rail-like protrusion 6 of the sash lower rail 5 is fitted into the groove 3 of the lower frame 1 and installed on the plurality of sash rollers 4 fixedly arranged in the hollow part, to erect the sash. The smooth sliding operation of the sash can be performed by a combination of the sash rollers 4 fixedly built in the lower frame 1, and the rail-like protrusion 6 of the lower rail of the sash. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

The present invention is a structural technical innovation related to the construction of sliding doors, sliding doors, the lower frame of sliding doors, doors, and shoji for steel fittings installed in the openings of buildings. Conventionally, in order to maintain an opening / closing mechanism and watertightness and airtightness, a plurality of protrusions such as rails and water return, grooves, steps, and the like have been formed on the lower frame. However, these are causes of traffic obstacles such as walking obstacles for the user, wheel pinching, wheel slipping, etc., and there are also problems from the hygiene aspect due to clogging of dust and dirt.
This is a review of the structural defects of the sliding doors and sliding frames such as sliding windows and sliding doors.

Sliding windows, sliding doors, and sliding doors, ranging from wooden to steel fittings, are traditionally built with a shoji with a door or a shoji attached to the lower arm of a shoji on the outer frame with a rail attached to the lower frame. The basic structure has not changed since history.
In this structure, it is unavoidable that various protrusions and grooves such as rails, water return, etc. are formed on the upper part of the lower frame of the opening through which people, objects and wheels pass. And has been a cause of accidents.

Problems to be solved by the invention

In recent years, barrier-free construction that ensures safety, convenience and comfort in the buildings of physically disabled and elderly people has become a requirement of the times, and sliding windows, sliding doors, sliding doors The function and structure are also requested to be reviewed.
In particular, the conventional sliding doors installed at the entrances and exits of buildings and the complex structures formed by protrusions and grooves on the lower frame of sliding doors are the cause of traffic obstacles and accidents. This is one of the urgent issues of making it free.

Means for solving the problem

  In order to solve the above-mentioned problems, the present invention reexamines the structure of sliding doors, sliding doors, and traditional fittings of sliding doors, and removes the rails in the lower frame with the idea of reverse rotation. A basic main part of joinery that secures a smooth surface at the top, abolishes the door roller that should originally be under the shoji, replaces it with a rail-shaped protrusion, and installs and fixes the door wheel in the lower frame. It was solved by changing the structure.

In order to carry out the present invention, the sliding window, sliding door, and lower frame (1) of the sliding door according to the first aspect of the present invention have a box-like cross-sectional shape, and the conventional upper frame rail, water A smooth surface (2) is secured by removing protrusions such as barbs, grooves, steps and the like from the upper part of the lower frame (1).
The smooth surface (2) of the lower frame (1) is provided with one or a plurality of thin grooves (3) through which the rail-like projections (6) of the lower arm of the shoji (5) pass when the shoji is built.
A plurality of door wheels (4) on which rail-shaped protrusions (6) are placed are housed and fixed in a box-shaped hollow portion of the lower frame (1).
For shoji, traditionally, the door trolley attached to the lower part of the lower armpit (5) has been removed, and instead the rail-shaped protrusion (6) that originally serves as the rail attached to the upper part of the lower frame is lowered. It shall be attached to the lower part of 框 (5).
The sliding operation of the entire shoji can be facilitated by installing the rail-shaped protrusion (6) of the lower arm (5) of the shoji into the door cart (4) installed inside through the groove (3) of the lower frame (1). .
The sliding window, sliding door, sliding door lower frame (7) according to the invention of claim 2 has a box-like cross-sectional shape, a conventional upper frame rail, projections such as water return, grooves, and steps are these. A smooth surface (8) is formed by removing the protrusion from the upper part of the lower frame (7).
The smooth surface (8) of the lower frame (7) is provided with one or a plurality of narrow grooves (9) through which the rail-like projections (6) of the lower arm (5) of the shoji are passed when the shoji is installed. .
A plurality of rollers (10) on which the rail-shaped protrusions (6) of the shoji are placed are housed and fixed in the box-shaped hollow portion of the lower frame (7).

The invention's effect

The present invention is a joinery comprising a combination of an outer frame having a lower frame without a rail and a shoji without a door as described in claim 1 or claim 2.
Unlike conventional sliding windows, sliding doors, and sliding doors, the upper portion of the lower frame has a smooth surface without a plurality of protrusions such as rails, grooves, and steps.
As a result, physically disabled people, elderly people, infants, and general users may be injured or fall while walking or using the wheel, or the wheel may be derailed or pinched, which may hinder their behavior. In addition, various obstacles such as dirt and dust accumulating in the groove and becoming unsanitary can be eliminated, and a safe, convenient and comfortable opening of the opening can be realized.
